This invention relates to a hinge construction. One of the objects of this invention is to provide a hinge which is simple and inexpensive in construction, and which is sturdy and durable under conditions of rigorous use. Another object is to provide a hinge particularly adapted for mounting an automobile door, for example. Another object is to provide a hinge whose various parts may be secured to a door frame and door in such a manner that all portions of the hinge are concealed when the door is shut. Other objects will be in part apparent and in part pointed out hereinafter.

The invention accordingly consists in the features of construction combinations of elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described and the scope of the application of which will be indicated in the following claims.

With reference to the drawing, in which is shown one embodiment of my invention,

Figure 1 is a perspective view of my hinge attached to a door and door frame;

Figure 2 is a horizontal section of the hinge in open position;

Figure 3 is a horizontal section of the hinge in its closed position; and,

Figure 4 is a sectional elevation taken along the line 4--4 of Figure 3.

30 Similar reference characters refer to similar parts throughout the several views of the drawing.

In many instances it is desirable for a door or other closure, because of its construction, to be movable bodily from its frame, in addition to being swingable therefrom. Hinges which have been provided to effect this double movement operate indifferently because of complication ofparts and structural weakness, because of which 40 the hinges become sprung and thereafter fail to function properly. Still other of these hinges are so bulky that they cannot be concealed. A further disadvantage lies in the fact that some hinges of this type do not effectively safeguard 45 against bodily relative movement between the door and frame when the door is closed, and

butt plate generally indicated at E3. Anchor plate 12 is secured to frame H] as by screws l4, swinging plate it being secured to door H as by screws l5.

Anchor plate l2 is substantially channelshaped in cross section, thus comprising a bottom portion I6, wall portions ll and l8, and oppositely directed flange portions l9 and 20, which extend toward one another to leave a space or opening therebetween. Preferably anchor plate I2 is set into frame it so that the outer surfaces of flanges l9 and 20 are flush with the surface of the frame. A pin 22 is secured to anchor plate bottom I6 adjacent the left-hand end thereof, as viewed in Figure 1, this pin being provided for a 15 purpose described hereinbelow.

Still referring to Figure 1, a sliding plate 23 is slidably disposed within channel-shaped anchor plate l2, and has in its left-hand end a slot 24, into which pin 22 fits when the sliding plate is moved to the left, the plate thus abutting against the pin to limit leftward sliding movement of sliding plate 23 in anchor plate !2, as viewed in the drawing.

Swinging plate l3 has a pintle receiving ear 25 25 formed on its left-hand end, as viewed in Figure 1, which fits between a pair of pintle receiving ears 26 and 21 formed on the righthand end of sliding plate 23. A pintle pin 28 pivotally connects ears 25, 26 and 27, thus pivotal- 30 ly or swingably securing swinging plate l3 to sliding plate 23, and accordingly effecting a pivotal relation between anchor and swinging plates 12 and i3. A hole or.slot 29 is formed in the right hand end of swinging plate l3, and pin 22 fits into this slot when the swinging and anchor plates are folded together From the above it will appear that door ll may be moved bodily outward, i. e., to the right as viewed in Figure 1, by virtue of the sliding relationship between anchor plate l2 and sliding plate 23. Furthermore, door ll may be swung or pivoted in conventional manner through the provision of the pivotal connection between the swinging plate and sliding plate 23. d When the door is closed, however, and all of the plates are in folded or nested relationship wherein pin 22 extends through slot 29, relative bodily movement between frame Ill and door ll is prevented by reason of the pin and slot, thus preventing inad- 5 vertent outward sliding movement of the door, which would cause it to become unlatched. The door might become unlatohed because of the fact that it could slide outwardly along its hinged edge sufliciently to unlatch any bolt or looking mechanism with which the other edge of the door might be provided. As pointed out, this is prevented by pin 22 and slot 29.

As viewed in Figure 2, frame 10 is provided with a recess 30, which houses an arcuate bar or guide hook 3|, one end 32 of which is joined to the right hand end of anchor plate bottom I6 (as viewed in Figure 2) and the other end 33 of which extends to a point adjacent the outer surface lOa of door frame Ill. The outer surface lfla. of the door frame has a slot 34 (see also Figure 3) formed thereon adjacent sliding plate 23, and this slot (Figure 2) receives an operating bar 35 which preferably is integrally formed with swinging plate 13 and extends substantially at right angles thereto. The left-hand end of operating bar 35, as viewed in Figure 2, is slotted as at 36 and this slot preferably has a curved or beveled edge 31 (Figure 3), which bears against the right-hand surface of guide hook 3| (Figures 2 and 3) during opening movement of the door. as viewed in the drawing.

Preferably the free end 38 of the operating bar 35 is reduced and rests against bottom it of anchor plate [2, when the door is open, adjacent portions of operating bar 35 being disposed within a slot 39 (Figure 4) in anchor plate bottom H When the door is opened, as shown in Figures 2 and 3, pivotal movement of door In separates anchor and swinging plates l2 and I3, causing Withdrawal of pin 22 from slot 29, and causing curved edge 3'! of operating bar 35 to engage the right-hand surface of guide hook 3|, as viewed in the drawing. All points of engagement between the operating bar and the guide hook are fulcrums about which swinging plate [3, considered as a lever, pivot to withdraw sliding plate 23 to the right, as viewed in the drawing, from within anchor plate l2. When door H is completely open, as shown in Figure 2, operating bar 35 abuts against sliding plate 23 and anchor plate l2, thus checking further opening movement of the door.

When the door is closed, substantially a reversal of operations takes place, and the abovenoted fulcrum points are now on the left-hand surface of guide hook 3|, as viewed in the drawing. Thus operating bar 35 swings clockwise and its free end slides along guide hook 3|, forcing sliding plate 23 to the left (Figure 3) until the anchor, sliding and swinging plates are nested. When the plates are in this position, all portions of the hinge are effectively concealed because preferably door I I includes a flange Ha which covers frame slot 34. Likewise, when the door is open, as shown in Figure 2, substantially all portions of the hinge are concealed when viewed from the exterior, as door flange I la substantially conceals the exposed portion of operating bar 35.

It may now be seen that door H is not only swingable out of frame in in the conventional manner, but is also bodily movable therefrom, the bodily movement being automatically effected by the swinging or pivoting movement. Furthermore, because of pin 22 and slot 29 (Figure 3) bodily movement is precluded when the door is shut. Also by reason of the rigidity and relative position of operating bar 35 (Figure 2) an effective door check is provided, thus obviating the necessity of providing the usual straps or other supplemental door checks. Still further, when the door is closed, no portions of the hinge are visible.

Thus I have provided a hinge which attains the above noted objects in a thoroughly practical and efiicient manner.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbcfore set forth, or shown in the accompanying drawing, is to be interpreted as illustrative and not in a limiting sense.
