Application September 15, 1939, Serial No. 295,136 15 Claims (01. 16 86) I I L of resilient material such as rubber or rubber This, invention relatesgenerally to door checks,"

1. e., devices forjlimiting the swinging movement of doors, and refers more particularly to door checks of the concealed type.

One of the essential. objects} of the invention is to provide a door check wherein provision is made for effectively absorbing or cushioning shocks resulting from checking the swinging movements of the doors.

Another object is to provide a strong and du rable door check that is simple in construction, economical to manufacture, and easy to install.

Other objects,.advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein: t

Figure 1. is a fragmentaryhorizontal sectional view through a swinging door supporting, hinge pillar therefor, and door check embodyingrny invention, and showing the arrangement of parts when the door is in closed position;

Figure 2 is a view similar to Figure 1, but showing' the door in open position;

Figure 3 is an end vow of the door check shown in Figures 1 and'2;1 f I g I Figure 4 is a detail view of the Washer illustrated in Figure 3;

Figure 5 is a side elevation of form of door check; H

I Figure 6 is a fragmentary longitudinal sectional view through the door check illustrated in Figure 5;

Figure '7 is an end view of the door check illustratedin Figures 5 and 6;

Figure 8 is a side elevation of another modified form of door check;

Figure 9 is a longitudinal sectional view through the door check illustratedin Figure 7;

Figure '10 is an end view of thedoor checkillus- .trated in Figures 8 and 9.

Referring now to the drawing, A is the head, B is the shank, and C is the shock absorbing or cushioning element of a door check embodying my invention. As shown, the head A and shank B are formed from one piece of relatively heavy spring wire and cooperate to hold the cushioning element C. Preferably the head A comprises the laterally bent end portions l and 2 of the wire, while the shank B comprises the. elongated I9 turn-bent portions 3 and 4, respectively, of the Wire. The return-bend of the wireis preferably opened slightly to provide an eye 5 for the reception of a suitable anchorage member such 'asB. The cushioning element 'Q'is preferably a block a slightly modified composition and is sleeved upon the shank B ad- 'jacent the head A. In this construction a washer D is also-sleeved on the shank B between the cushioning element C and head A and serves as a tieor coupling between the return-bent portions 3 and 4 of the Wire at the free ends of the latter. As shown the washer D has a central slot I of sufficient length to receivethe eye 5 when the washer is sleeved upon the shank and is provided in opposite edges of said slot with notchest and 9 for receiving the shank portions 3 and 4 of thewire. Preferably the slot 1 and notches B and 9 are so formed that the washer D may be turned 90 on the shank B from the In use the door check extends substantially hori'zontally between the door E andits supporting hinge pillar F. As. shown, the anchorage member 6 is in-itheform of a pin and is carried by two spaced angle plates ID, fixed to the door E. The hingepillar F is hollow and is provided in one wall I l thereof with a slot l2 for receiving the shank B of the door check. Thecushioning element C, washer D, and head A are located within the hollow pillar so that the cushioning element C is engageable with thewall II to limit the outward swinging movement of the door when the-latter is opened. However; it is apparent that the arrangement just described may be reversed, i. e., the anchorage memberfi may be secured to the hinge pillar F and the, door E. may be apertured to receive the shank B. In either instancethe door E would be yieldably checked when opened. I

In Figures 5, 6 and '7 I have illustrated a slight modification in which the washer D isprovided upon opposite sides of the slot 1 with two holes head A itself sufiices. Actually the 'S-shape of the head is such that added spring action to the cushioning element C is aiforded.

In each instance where wire is used it is to be understood that the wire is tempered spring steel.

Thus, from the foregoing it will be apparent that the door checks shown and described herein are simple yet strong and durable in construction and can be manufactured at a comparatively low cost. It also will be apparent that each form shown includes means for effectively cushioning or absorbing shocks resulting from checking the swinging movements are applied.

What I claim as my invention is:

1. A door check having a shank provided at one end with an eye and provided at the other end with a head, said shank being formed of wire return-bent upon itself, a yieldable cushioning element on said shank, and an abutment for said element on said shank against said head and having means for holding the return-bent portions aforesaid of said wire in a predetermined relation to each other.

2. A door check having a shank provided at one end with an eye and provided at the other end with a head, said shank being formed of Wire return-bent upon itself, a yieldable cushioning element on'said shank, and an abutment for said element on said shank against said head, said abutment having a slot for receiving said eye and provided in opposite edges of said slot with notches for receiving the return-bent portions of said wire.

3. A door check having a shank provided at one end with an eye for receiving an anchorage member and provided at the other end with a head, said shank, eye and head being formed from one piece of spring wire, a washer on said shank and having holes therein receiving portions of said head, and a compressible cushioning element on said shank against said Washer.

4. A door check having a shank and a cushioning element carried thereby, the shank being formed from a single strand of 'wire return-bent upon itself and provided at one end with a head and provided at the other end with an eye, the head comprising laterally bent end portions of the wire, the eye comprising an opened part of the return-bend of the wire, and the cushioning element being sleeved upon the shank adjacent said head.
