Definitions
- an embodiment of the present invention overcomes the disadvantages of the prior art spring hinges by having a unitary hinge and spring member all molded integrally as one piece without the necessity of a separate connecting arm.
- the result is a hinge that may be barely detectable in either an open or a closed position.
- a unitary spring hinge is produced which can be molded of plastic material integrally with the rest of the total device to form a product of high aesthetic value. It may thus advantageously be used in decorative containers or boxes without the necessity of such being lined or otherwise treated to conceal the spring elements. It is also suitable for use as a spring hinge for eyeglass frames and may indeed also be produced as a spring hinge for attachment by screws, cement or the like in cabinets, chests and similar articles of furniture.
- This invention relates to a design for a unitary hinge and spring device which may be molded of a plastic material such as polypropylene.
- the two hinge plates are formed integrally with the product, the plates themselves being connected to each other by a thin web of plastic material to form a first bending line.
- a resilient spring member having a cross-sectional shape of a C and having its ends joined to the plates and serving as an over-the-center" or toggle spring to provide the energy to retain the hinge in either of two alternate end positions of travel.
- a further object of this invention is to provide a unitary spring hinge structure which will be of high aesthetic value and suitable for use in decorative containers without the necessity of their being lined or otherwise covered to conceal the hinge and spring member and with a neat appearance when viewed from the outside.
- a further object of this invention is to provide a hinged product having a hinge and spring member that may be molded so as to be barely visible in the finished product.
- a further object of one embodiment of the invention is to provide a spring hinge which may be integrally molded as a part of a container without the necessity of utilizing cam operated moving parts in the molding equipment.
- FIG. I is an isometric view of the spring hinge of one embodiment of this invention.
- FIG. 2 is a fragmentary cross-sectional view of a modified form of a spring hinge in one rest position.
- FIG. 3 is a cross-sectional view of said hinge in a position of maximum stress.
- FIG. d is a cross-sectional view of said hinge in an opposite rest position from that of FIG. 2.
- FIG. 5 is a three-dimensional view of the spring hinge of this invention as applied to a box, such as a cigarette box, in a closed position.
- FIG. 6 is a view similar to FIG. 5 but showing said hinge in an open position.
- FIG. 7 is an enlarged fragmentary cross-sectional view of the spring hinge as found in FIGS. 5 and 6, showing said hinge in an open position.
- FIG. 8 is a view similar to FIG. 7 but showing said hinge in a closed position.
- FIG. 9 is a fragmentary cross-sectional view of another embodiment of the spring hinge of this invention in a rest position.
- FIG. 10 is a cross-sectional view similar to FIG. 9 but in a position of maximum stress.
- FIG. III is a cross-sectional view of the hinge similar to FIGS. 9 and Ill) but in an opposite rest position from that shown in FIG. 9.
- FIG. 12 is a cross-sectional view of another embodiment of this invention in a container or box.
- FIG. I3 is a cross-sectional view of still another embodiment of the invention.
- the hinge of this invention consists of two plate members I0 and Ill hingedly molded and held together by a thin layer of plastic material forming first bending line I2 sometimes called a living hinge. Formed partially in each plate member when said plate members abut is aperture 14. Molded integrally to each respective plate member at the edges of aperture ll4l parallel to first bending line 12 is an arcuate spring member I6, formed generally in the shape of a C. However, as is shown in FIGS.
- the shape of spring member 16 may be somewhat varied from the shape of a C and be within the scope of this invention.
- said plate members are integrally formed as part of the'wall of the product and reference to the plate members as such is done merely for ease in describing the present invention, since the plate members need not protrude from either the inside or outside wall of the product or container, as is best shown in FIGS. 5 and 6.
- said plate members are abruptly thinned or angled to form a thin layer of plastic material which operates to form first bending line 12 so that each plate member may pivot with respect to each other.
- the edges of plate members I0 and Il may be constructed so that end shoulders 10a and 11a contact each other and serve as a stopping means.
- Aperture 14 formed in plate members I0 and Il may be symmetrically oriented with respect to bending line I2.
- FIG. 13 an embodiment, shown in FIG. 13, is possible wherein said aperture is oriented more in one plate member than the other. In this case the length of aperture 14 from first bending line 12 would extend further into one plate than it would into the other plate 11, for example.
- the dimensions and requirements of the aperture are determined by the requirements of a particular product in which the spring hinge is to be employed.
- the orientation of the aperture influences the total distance travelled by said plate members from one rest position to another, since said spring member arcuately bridges said aperture.
- plate members 10 and 11 adjoin spring member 16, they are thinned or angled to form second and third bending lines 18 and 20, in each respective plate member. Bending lines 18 and 20 are formed in a similar manner to first bending line 12 and said bending lines provide the means for said spring member to pivot along with said plate members. Plate members 10 and II and spring member 16 may also be thinned or angled so as to serve as a stopping means as is best shown in FIG. 4.
- Resilient spring member 16 functions both as a spring means and a connecting link between each plate member and is designed so that it has a resistance to elongation.
- spring member 16 When in operation, as the plate members are pivoted form one rest position, such as in FIG. 2, to another, as shown in FIG. 4, spring member 16 will have to be stretched and since the plastic material employed in this in vention is elastic, said spring member tends to return to its original shape.
- the elastic property of said spring member has been found to be most pronounced when its intermediate portion is thicker than the end portions adjoining each plate member. However, embodiments are possible which employ a spring member of uniform thickness.
- FIG. 2 the plate members and hinge are in what can be arbitrarily referred to as a first rest position.
- a first distance between second bending line 18 and third bending line 20 is represented in FIG. 2 by the arrow lettered y. If plate member 10 is moved in a direction of arrow 22, the result would be an increase in the distance between second bending line I8 and third bending line 20.
- the resilient spring member 16 is so designed that a force will have to be exerted to overcome the elastic energy of tension within resilient member 16. As movement of plate member 10 is continued to the position indicated in FIG.
- the invention is not intended to be limited to such a design, since an embodiment is possible wherein the distances between said second and third bending lines and said first bending lines are not equal.
- said plate members cannot be molded in a straight line since said spring member would then resist any pivotal movement of said plate members.
- the spring hinge When positioned in the mold in the molding process the spring hinge must occupy the position that is to be one of the rest positions in the molded product. Further movement of plate member 10 in the direction of arrow 23 (FIG. 3) results in a decrease in the distance between second bending line 18 and third bending line 20.
- the energy of the spring member 16 tends to return said bending lines to a second distance represented in FIG. 4 by the arrow y. That is the shortest distance possible between said bending lines with the embodiment.
- the energy of spring member 16 is arrested by end shoulders l3, of said spring member coming in contact with plate members I0, II, respectively.
- FIGS. 5 and 6 show an embodiment of the spring hinge in a container or box such as a cigarette box indicated by numeral 24 having a body 26 and a cover 28. As is shown in the drawing, the entire unit forms a handsome and attractive container in which spring member 16 blends in with the rest of the total device producing a streamlined effect in either the open or closed position.
- FIGS. 7 and 8 illustrate the principle of operation of the embodiment asfound in FIGS. 5 and 6 to be identical to that previously explained with reference to FIGS. 2-4.
- the cigarette box as shown in FIG. 7 is in an open position.
- spring member 16 will have to be stretched and in its travel will pass through the theoretical unstable equilibrium position until it finally comes to an alternate position of rest.
- body 26 of box 24 serves as a stopping means by making contact with cover 28 and thereby arresting the motion of said hinge prior to its reaching the rest position.
- FIGS. 9-12 show another embodiment of this invention.
- This embodiment contains no undercut.
- the phrase undercut refers to a process in which a side action motion is required to remove the part from the mold in the ejection molding process.
- the reference point in determining the upper part of the mold is the direction of ejection represented by arrow 30 (FIGS. 9 and 12).
- the hinge is so designed to eliminate production costs and the necessity of cams within the ejection mold to remove interfering properties in the mold which would prevent removal of the product from the mold. Elimination of undercutting within the mold is achieved by a design wherein resilient spring member 16 is integrally joined to plate member 11 by offsetting said spring member from the planes of the walls of said plate member so that the total amount of plastic material forming said spring member only extends within the planes of the walls of said plate member by a distance equal to or less than the thickness of the thin web of plastic material forming the third bending line. It is to be understood that the above description applies to the formation of third bending line 20 but could apply also to the formation of second bending line 18. In the embodiment shown in FIG.
- FIG. 10 shows said spring member in a position of maximum elongation or theoretical unstable equilibrium.
- the distance between second bending line 18 and third bending line 20 is decreased from that shown in FIG. 10.
- the elastic energy of the spring member tends to bring the plate members together so that said second and third bending lines are as close as the construction of the hinge allows once past the theoretical unstable equilibrium position.
- the spring hinge in FIG. II is in a rest position, due to the stopping action of plate members 10 and 11 contacting each other.
- the spring hinge is generally molded of polypropylene, but any other material having the desired properties of moldability and flexibility in thin sections without breakdown are contemplated and within the scope of this invention.
- an embodiment may be employed as a spring hinge for eyeglass frames and any number of products which employ a spring hinge.
- an arcuate toggle spring formed of a relatively rigid but resilient substantial thickness of said molded material, said spring extending arcuately away from and over said main bending line spanning said aperture and having each of its opposite ends connected to a respective one of said plate portions by additional thin linelike flexible sections of said molded material which form second and third bending lines of said hinge at respective opposite ends of said aperture, said second and third bending lines being parallel to said main bending line but respectively offset therefrom in said extensions of said aperture whereby said arcuate spring serves to resiliently urge said plate portions in either of two permissible directions of bending along said main bending line away from an aligned relationship with each other and thereafter to resiliently retain said plate portions in one of said nonaligned relationships.
