Description
- The present application claims priority under 35 U.S.C. §119 to Japanese Patent Application No. 2007-6393 filed on Jan. 15, 2007. The content of the application is incorporated herein by reference in its entirety.
- The present invention relates to a holding mechanism for foldable side rails of a bed, especially for foldable side rails that have plural stanchion members pivotally rotatably connected between an upper horizontal rail member and a lower horizontal rail member, to form a parallel link mechanism, wherein said holding mechanism is provided for keeping the stanchion members erect.
- Various rails have been proposed as side rails of beds. Among them, a conventional technique of foldable side rails that have plural stanchion members pivotally rotatably connected between an upper horizontal rail member and a lower horizontal rail member, to form a parallel link mechanism, wherein a holding mechanism is provided for keeping the stanchion members erect is described, for example, in Japanese Patent No. 3029026.
- In the foldable side rails described in the patent document, the holding mechanism is provided at an end of the upper horizontal rail member and comprises a mechanism support member connected with the stanchion member provided at the end; the mechanism support member has a stopper pin set biased in the advancing direction by a spring; the stanchion member has a fitting hole capable of having the stopper pin set fitted in it when the stanchion member is kept erect; a release action site for allowing the stopper pin set to recede against the force of the spring is provided directly at the rear of the stopper pin set; and the bottom side of the release action site is exposed downward from the bottom of the mechanism support member. Further, the mechanism support member has a lock member capable of being moved between the release preventing position and the release allowing position for the release action site.
- In the above constitution, when the stanchion members are kept erect, with the tip of the stopper pin set fitted in the fitting hole, the side rails have the upper horizontal rail member kept at the highest position in the state of use. In this constitution, a slope face for allowing the stopper pin set to slide on it is formed near the fitting hole, so that when the horizontal rail members are raised to keep the stanchion members erect, the stopper pin set can be automatically fitted into the fitting hole.
- In the case where the lock member is set at the release preventing position with the stopper pin set fitted in the fitting hole, even if the release action site exposed downward from the bottom of the mechanism support member is accidentally touched to apply a force in the release allowing direction, the release action site is prevented from moving by the lock member and cannot move. Therefore, the tip of the stopper pin set remains fitted in the fitting hole, and the stanchion members and the horizontal rail members are kept in the state of use safely.
- The conventional foldable side rails as described above have the following disadvantages.
- 1. The release action site provided of the stopper pin set is exposed downward from the bottom of the mechanism support member. So, if a force in the release allowing direction is applied owing to an accidental touch in the case where the lock member is not set at the release preventing position, it can dangerously happen that the stopper pin set is disengaged from the fitting hole and that the stanchion members fall while the upper horizontal rail member drops.
- 2. In the stowed state where the stanchion members fall while the upper horizontal rail member is kept at the lowest position, if the lock member is moved to the release preventing position and the horizontal rail members are raised to keep the stanchion members erect, then the stopper pin set is kept projected to interfere with the stanchion member having the fitting hole. Therefore, the stopper pin set cannot be automatically fitted into the fitting hole.
- The object of this invention is to solve the above problems.
- To solve the above-mentioned problems, this invention proposes a holding mechanism for foldable side rails that have plural stanchion members pivotally rotatably connected between an upper horizontal rail member and a lower horizontal rail member, to form a parallel link mechanism, said holding mechanism being provided for keeping the stanchion members erect, characterized in that the holding mechanism is provided at an end of the upper horizontal rail member and comprises a mechanism support member connected with the stanchion member provided at said end; the mechanism support member has a stopper pin set capable of advancing and receding; the stopper pin set is biased in the advancing direction by a spring; the stanchion member provided at the end has a fitting hole for allowing the stopper pin set to be fitted in it when the stanchion member is kept erect; the mechanism support member further has a release lever engaged with a mechanically driven trigger site provided in connection with the stopper pin set, for making the stopper pin set recede against the force of the spring; a play mechanism is provided between the release lever and the mechanically driven trigger site; and the mechanism support member further has a release prevention mechanism for preventing the movement of the release lever in the release allowing direction.
- This invention proposes said constitution, wherein the play mechanism consists of a slot formed in the mechanically driven trigger site and a pin installed in the release lever and engaged with the slot.
- This invention proposes said composition, wherein the play mechanism consists of a recess formed in the mechanically driven trigger site and opening in the horizontal direction and a pin installed in the release lever and engaged with the recess.
- This invention proposes said composition, wherein as the release prevention mechanism, a lock member with a contact portion to be kept in contact with the upper face of the release lever is movably provided in the upper portion of the mechanism support member, while a recess designed to avoid contact with the contact portion is formed in the upper face of the release lever, in the case where the release lever is moved upward for release action. In this case, the recess can be formed as the lower horizontal one of two horizontal levels.
- This invention proposes said constitution, wherein as the release prevention mechanism, the lock member is biased by a spring in the direction in which the release prevention mechanism acts.
- This invention proposes said constitution, wherein the mechanism support member can function as a cover for covering mechanism components and has a pocket formed partially in the place where the release lever is pressed for release action.
- In the foldable side rails of this invention, the holding mechanism used to keep the stanchion members erect has a play mechanism formed between the release lever and the mechanically driven trigger site. So, even in the state where the release prevention mechanism for preventing the movement of the release lever in the release allowing direction is set at the release preventing position, when the horizontal rail members are raised to keep the stanchion members erect, the stopper pin set can be automatically fitted into the fitting hole.
- The release lever to be pressed for release action is exposed in the pocket of the mechanism support member, that is, the place in which the release lever is pressed for release action is contained in the pocket. So, an accidental action error can be prevented.
- The lock member as the release prevention mechanism can be manually moved in both the release preventing direction and the release allowing direction, or can also be biased in the release preventing direction by a spring and manually moved in the release allowing direction against the force of the spring.
- In the latter case, a failure to move the release prevention mechanism in the release preventing direction can be avoided highly safely.

The first embodiment of theholding mechanism 4 of this invention is explained below in detail in reference to these drawings. - As shown in the drawings, the
stanchion member 2, namely, thestanchion member 2 at the left end ofFIG. 1 in this case, is pivotally rotatably connected with themechanism support member 5 at apivot 8. Amember 9 attached to thestanchion member 2 has afitting hole 10 formed, and themember 9 has aslope portion 11 formed beside thefitting hole 10. - On the other hand, the
mechanism support member 5 supports a stopper pin set 12 at a position corresponding to the position of thefitting hole 10 when thestanchion member 2 is kept erect, in such a manner that the stopper pin set 12 can advance and recede, namely, can move vertically in the drawings. The stopper pin set 12 is biased in the advancing direction, namely, downward in the drawings, by aspring 13 such as a compression coil spring. Meanwhile, as shown in the drawings, the stopper pin set 12 has a small diameter portion projected at its tip, to be fitted in the fitting hole.Symbol 14 denotes a cylinder for supporting the stopper pin set 12 in such a manner that the stopper pin set 12 can advance and recede. At the rear of the stopper pin set 12, namely, above the stopper pin set 12 in the drawings, a mechanically driventrigger site 15 is formed, and the mechanically driventrigger site 15 has aslot 16 formed in the vertical direction. - On the other hand, in the
mechanism support member 5, therelease lever 6 is pivotally rotatably supported by apivot 17, and thelower side portion 6 d of therelease lever 6 is exposed as a hand trigger site in thepocket 7. - The upper side portion of the
release lever 6 protrudes above, and arecess 19 is formed on the left side of aprotrusion 18 on the right side. - Further, on the left side of the
release lever 6, apin 20 is installed. Thepin 20 is engaged with theslot 16 formed in the mechanically driventrigger site 15 at the rear of the stopper pin set 12. - Furthermore, at the top of the
mechanism support member 5, alock member 22 capable of moving in the horizontal direction in the drawings is provided in aslot 21 formed in the horizontal direction in the drawings. On the lower side of thelock member 22, aprotrusion 23 is formed in such a manner that it can contact theprotrusion 18 of therelease lever 6, and on the upper side of it, aprotrusion 24 is formed to be used for moving the lock member. Moreover, as shown inFIGS. 11 and 12 on the underside of the top plate of themechanism support member 5,projections 25 are formed on both sides to hold thelock member 22 moving in the horizontal direction in position, anddepressions 26 corresponding to them are formed in thelock member 22. - In the above constitution, in
FIG. 5 , thestanchion member 2 is kept erect, and the tip of the stopper pin set 12 is fitted in thefitting hole 10, being biased by thespring 13. Therefore, thestanchion member 2 is held in such a manner that it cannot be rotated around thepivot 8 relatively to themechanism support member 5, hence the upperhorizontal rail member 1 u. So, in the side rails, thestanchion member 2 is kept erect and the upperhorizontal rail member 1 u is kept at the highest position. Further, inFIG. 5 , thelock member 22 is kept in the state ofFIG. 11 , and therefore, therelease lever 6 can be pressed for release action. - In the case where the
lock member 22 is moved rightward as shown inFIG. 6 , to reach the state ofFIGS. 6 and 12 , even if thehand trigger site 6 d of therelease lever 6 is pressed upward, therelease lever 6 cannot be moved upward at all, since theprotrusion 18 of therelease lever 6 contacts theprotrusion 23 of thelock member 22. - In this embodiment as described above, since the
hand trigger site 6 d of therelease lever 6 is contained in thepocket 7 formed in themechanism support member 5 functioning as a cover, it is difficult to accidentally press thehand trigger site 6 d, and even if thehand trigger site 6 d is accidentally pressed, thelock member 22 prevents the accidental movement of therelease lever 6, to assure double safety. - In the case where the side rails are stowed, that is, in the case where the
stanchion members 2 are pivotally rotated to descend for lowering the upperhorizontal rail member 1 u, thelock member 22 is moved leftward in the drawings, to reach the released state ofFIGS. 5 and 11 , and subsequently thehand trigger site 6 d exposed in thepocket 7 is manually pressed upward. As a result, therelease lever 6 is rotated around thepivot 17 clockwise in the drawings. The pivotal rotation moves thepin 20 upward, and the pin moves the top end of theslot 16. So, the mechanically driventrigger site 15 moves the stopper pin set 12 upward against the force of thespring 13. Thus, as shown inFIG. 7 , the tip of the stopper pin set 12 recedes to be disengaged from thefitting hole 10. - In this state, the
stanchion member 2 can be pivotally rotated from the state ofFIG. 8 to the state ofFIG. 9 , and therefore, the upperhorizontal rail member 1 u can be lowered in parallel in the parallel link mechanism. - On the contrary, if the upper
horizontal rail member 1 u is raised from the state ofFIG. 9 to the state ofFIG. 8 , and further raised to pivotally rotate thestanchion member 2 relatively clockwise inFIG. 8 , theslope portion 11 of themember 9 makes the stopper pin set 12 recede as shown inFIG. 10 , and then when the stopper pin set 12 corresponds to thefitting hole 10, the force of thespring 13 causes the stopper pin set 12 to fit in thefitting hole 10. Thus, the fitting state shown inFIGS. 5 and 2 can be automatically achieved. - As can be seen also from
FIG. 10 , since a play mechanism, namely, a play mechanism consisting of theslot 16 formed in the mechanically driventrigger site 15 and thepin 20 installed in therelease lever 6 is provided between therelease lever 6 and the stopper pin set 12 in this invention, the stopper pin set 12 and the mechanically driventrigger site 15 can be moved without giving an external force to therelease lever 6, when the upperhorizontal rail member 1 u is raised. - So, in the state of
FIG. 8 , even if thelock member 22 is brought to the position ofFIGS. 6 and 12 , the stopper pin set 12 can be made to recede from thefitting hole 10 as in the state ofFIG. 10 . Therefore, as inFIG. 10 , theslope portion 11 of themember 9 makes the stopper pin set 12 recede, and then when the stopper pin set 12 corresponds to thefitting hole 10, the force of thespring 13 causes the stopper pin set 12 to fit in the fitting hole. Thus, the fitting state shown inFIG. 5 can be automatically achieved. - Thus in this invention, in other than the case where the
release lever 6 is pressed for inclining thestanchion member 2 from the state where thestanchion member 2 is kept erect, thelock member 22 can be kept in the lock state to enhance safety. - Meanwhile, in the first embodiment described above, the play mechanism consists of the
slot 16 formed in the mechanically driventrigger site 15 and thepin 20 installed in therelease lever 6. However, another appropriate play mechanism as shown in the following second embodiment can also be applied. -
FIGS. 13 through 15 show a second embodiment of the holding mechanism for foldable side rails of this invention. This embodiment is different from the first embodiment in the play mechanism and the release prevention mechanism only. So, the corresponding components are given the same symbols. - As shown in
FIGS. 13 through 15 , astanchion member 2 is connected with amechanism support member 5 in such a manner that it can be rotated around apivot 8. Further, amember 9 attached to thestanchion member 2 has afitting hole 10 formed and further has aslope portion 11 formed beside thefitting hole 10. - The
mechanism support member 5 supports a stopper pin set 12 at a position corresponding to the position of thefitting hole 10 when thestanchion member 2 is kept erect, in such a manner that the stopper pin set 12 can advance and recede, namely, can move vertically in the drawings. The stopper pin set 12 is biased in the advancing direction, namely, downward in the drawings, by aspring 13 such as a compression coil spring. Meanwhile, as in the first embodiment, the stopper pin set 12 has a small diameter portion projected at its tip and fitted in thefitting hole 10, as shown in the drawings.Symbol 14 denotes a cylinder for supporting the stopper pin set 12 in such a manner that the stopper pin set 12 can advance and recede. At the rear of the stopper pin set 12, namely, above the stopper pin set 12 in the drawings, a mechanically driventrigger site 15 is formed, and the mechanically driventrigger site 15 has arecess 27 formed to open in the horizontal direction. - In the
mechanism support member 5, therelease lever 6 is supported in such a manner that it can be rotated around apivot 17, and thelower side portion 6 d of therelease lever 6 is exposed as a hand trigger site in thepocket 7 formed in themechanism support member 5. - Further, the upper side portion of the
release lever 6 is formed to have two horizontal levels, with the upper horizontal level on the left side and the lowerhorizontal level 19 on the right side. - A
pin 20 is installed on the left side of therelease lever 6, and thepin 20 is engaged with therecess 27 of the mechanically driventrigger site 15 of the stopper pin set 12. Meanwhile,symbol 31 denotes a guide member. - Further, the
mechanism support member 5 supports alock member 22 above the upper side portion of therelease lever 6 in such a manner that the lock member can move horizontally in the drawings, and on thelock member 22, a lock member-movingprotrusion 29 is formed. The lock member-movingprotrusion 29 protrudes outside themechanism support member 5 through ahorizontal slot 21. Thus, the lock member can be moved in the horizontal direction, and the lock member-movingprotrusion 29 can be used to move the lock member. - In this embodiment, the
lock member 22 is biased leftward by a spring such as a compression coil spring. Further, thelock member 22 has aprotrusion 28 formed under its tip on the left side, which contacts the upper side portion of therelease lever 6. - In the above constitution, in
FIG. 13 , thestanchion member 2 is kept erect, and the tip of the stopper pin set 12 is fitted in thefitting hole 10, being biased by thespring 13. Therefore, thestanchion member 2 is held in such a manner that it cannot be rotated around thepivot 8 relatively to themechanism support member 5, hence the upperhorizontal rail member 1 u. So, in the side rails, thestanchion member 2 is kept erect and the upperhorizontal rail member 1 u is kept at the highest position. - In this case, the
lock member 22 is biased leftward by thespring 30, and contacts the upper horizontal level of the upper side portion of therelease lever 6. In this state, even if thehand trigger site 6 d of therelease lever 6 is pressed upward, therelease lever 6 cannot be moved upward at all, since the upper side portion of therelease lever 6 contacts theprotrusion 28 of thelock member 22. - In this embodiment as described above, since the
hand trigger site 6 d of therelease lever 6 is contained in thepocket 7 formed in themechanism support member 5 functioning as a cover, it is difficult to accidentally press thehand trigger site 6 d, and even if thehand trigger site 6 d is accidentally pressed, thelock member 22 prevents the accidental movement of therelease lever 6, to assure double safety. - Meanwhile, in the case where the lower
horizontal level 19 is formed as one of two horizontal levels as in this embodiment, thelock member 22 is not necessarily required to have theprotrusion 28. Further, if theprotrusion 28 is formed, the upper side portion of therelease lever 6 can have protrusions on both sides instead of forming the two horizontal levels including the lowerhorizontal level 19. - In the case where the side rails are stowed, that is, in the case where the
stanchion member 2 is pivotally rotated to decline for lowering the upperhorizontal rail member 1 u, at first, the lock member-movingprotrusion 29 is moved rightward in the drawings against the force of thespring 30 as shown inFIG. 14 . - Then in this state, if the
hand trigger site 6 d exposed in thepocket 7 is manually pressed upward, therelease lever 6 is rotated around apivot 17 clockwise in the drawings. This pivotal rotation moves thepin 20 upward, and thepin 20 moves the top end of therecess 27. So, the mechanically driventrigger site 15 moves the stopper pin set 12 upward against the force of thespring 13. Thus, as shown inFIG. 15 , the tip of the stopper pin set 12 recedes to be disengaged from thefitting hole 10, and in this state, thestanchion member 2 can be pivotally rotated as shown by the two-dot-dash line ofFIG. 15 . Therefore, the upperhorizontal rail member 1 u can be lowered in parallel as a parallel link mechanism. - Then, if the upper
horizontal rail member 1 u kept lowered is raised without pressing therelease lever 6, to pivotally rotate thestanchion member 2 clockwise relatively from the state of the two-dot-dash line to the state of the solid line, theslope portion 11 of themember 9 makes the stopper pin set 12 recede as in the first embodiment, and subsequently when the stopper pin set 12 corresponds to thefitting hole 10, the force of thespring 13 causes the stopper pin set 12 to be fitted in thefitting hole 10. Thus, the fitting state shown inFIG. 13 can be achieved automatically. - That is, since a play mechanism, namely, a play mechanism consisting of the
recess 27 formed in the mechanically driventrigger site 15 and thepin 20 installed in therelease lever 6 is provided between therelease lever 6 and the stopper pin set 12, the stopper pin set 12 and its mechanically driventrigger site 15 can be moved without giving an external force to therelease lever 6, when the upperhorizontal rail member 1 u is raised. So, even if thelock member 22 is moved to the release prevention side of the release prevention mechanism by the force of thespring 30, the state ofFIG. 13 can be achieved without any problem. - Thus in this invention, in other the case where the
release lever 6 is operated in the state where thestanchion member 2 is kept erect, the lock member can be automatically kept in the lock state by the force of thespring 30 to enhance safety. - In the above explanation, in the release prevention mechanism of the first embodiment, the lock member can be manually moved in both the release preventing direction and the release allowing direction, and the release prevention mechanism of the second embodiment is biased in the release preventing direction by a spring and manually moved in the release allowing direction against the force of the spring. Contrary to the above, the lock member in the release prevention mechanism of the first embodiment can be biased by a spring, or the lock member in the release prevention mechanism of the second embodiment can be moved manually without the force of a spring.
- The holding mechanism for foldable side rails of this invention as described above has the following features.
- 1. Even in the state where the release prevention mechanism for preventing the movement of the release lever in the release allowing direction is set at the release preventing position, when the horizontal rail members are raised to keep the stanchion members erect, the stopper pin set can be automatically fitted into the fitting hole.
- 2. The release lever is pressed for release action in the place exposed in the pocket of the mechanism support member, that is, the place in which the release lever is pressed for release action is contained in the pocket. So, an accidental action error can be prevented.
- 3. If the release prevention mechanism is biased automatically by a spring, safety can be further enhanced.
- The foldable side rails of this invention can be used to partially cover a lateral side of a bed or to entirely cover a lateral side of a bed. They can also be attached to a bed by any appropriate method.
