DOORCHECK.
Application filed September 22, 1919. Serial No. 325,378.
door, so as to check its velocity, in case it is suflicient to cause any serious slamming; and yet which will permit free closure of the door if the velocity is slow. I
The adapted manners of constructions of my invention have been illustrated in the accompanying drawings and in the following specification the construction of this device will be described and the combinations and parts which I believe to be novel, and upon which I desire patent protection, will be defined more fully in the claims.
Figures 1 and 9 show sections of a door in front elevations, illustrating the manners of applying my invention to a door jamb.
Figures 2, 3, 6, 10 and 13 are front views of the device, where a portion or the whole of the perpendicular position of bumper 31 is shown by solid lines, and its position, when swung into the path of the door, is shown by dotted lines.
Figures 4;, 7 '11 and 14 are side views of the device from the side neXtt-o the door.
Figures 5, 8,12 and 15-are top views of operating parts exposed to In the several'figures the same numbers an'd'c'haracters refer to the same parts.
I have shown my device as mounted and inclosed within a casing, consisting of two sidesor parts 10' '10, similar in shape [and size, and the edges about which may consist of aseparate strip, as shown in F igures 3 and 4, or may be formedout of the sides 1010 by being bent to 1116611011 an 'even line together, as shown in Figures 7, 11 and 14, but leaving the edge which is next -to the door in the main open. These parts may be secured together in any convenient man'n'er,.as-by use of rivets and screws, as at 12, 12 13,14,14 14 18 and 19., Pivot 15 is located nea the upper end of the device and close to the edge which is next to oor. I The device is secured to the door j amb so that the straight open edge substantially matches with the edge of the jamb or is in such position that it will nicely clear the edge of the door when swinging. Mounted upon pivot 15 is a suspender 2; secured to this suspender and projecting outwardly through openings in the casing, as at 18, 20
a striker; that is it is struck by the edge of the door in closing; and is shaped so as to be easily pressed laterally, or away from the swinging edge of the door, which is provided with a plate 4? for engaging said striker, and which also tion to the door.
As shown on the drawings this-striker is composed of a bent and curved bar, which,
gives wearing protecas shown in Figures 1 to 5, has its outward" projecting portion bent into the approximate shape of an oval ordiamond and, as shown in Figures 6 to 15, is more oblong in shape, of which, however, one edge or side normally projects into the path or swing of the door. This device might be made of other forms. The essential feature is that it should have a portion so shaped and po sitioned, that itmay with the least friction and 20 is a member 4:, which functions as be engaged by the door in swingingso as to be easily pressed outward thereby.
The lower or swinging end of suspender 2, at the 'point 30, is pivoted or jointed to supportv 3, which should be suitably shaped to engage recoil stop 16 and has, secured to the lower or swinging end thereof, a resilient bumper 31, which is intended for'insertion between the jamb and the door and the swinging edge of the door so as to check the door and prevent slamming; a suitable material for this would be rubber, or any equivalent resilient material.
In Figures 2, 6, 10 and 13 the normal position of this bumper outside of the swing of the door, is shown by solid lines, and the position thereof when swung into the path of the door, is shown by dotted lines.
Towards the edge of the casing whichis away from the door are placed recoil stops 16 and 18, which may suitably be bolts or rivets, and the former is provided with an enclosing cylinder or roll17. These stops are so'positioned in the casing that when the bumper support 3 is raised, or swung outward due to the swinging of suspender 2, by
-reason of engagement of the door with striker 4, the bumper 31 will be raised without projecting beyond the edge of the easing, if this movement be gradual and slow.
If, however, the movement of the door is swift, such as would, if unchecked, produce slamming, and in consequence striker l is sharply struck by the edge of the door, the support 3 will strike recoil stop 16 sharply, and whereby bumper 31, attached to the lower swinging end of said support, will be thrown upward and outward, either to the positions shown by solid lines in Figure 3 and by dotted lines in Figures '6, 10 and 13; or sufficiently far in that direction to cause a part thereof to be projected into the path of the door. The door striking the bumper 31 and the latter being of compressible or resilient material, the door will be gradually checked and without producing any slamming effect. As soon as the door has reeoiled enough to release the bumper, it will drop back into its perpendicular position in the casing, and the shutting of the door is completed, This operation is, however, not a mechanical certainty without the use of stops 18, 20, 20 and 21, which have the purpose of limiting the lateral movements of suspender 2, which is essential for obtaining the foregoing results. It is thus seen that the operation of this device depends upon a sharp blow producing a recoil, and the momentum of the parts being such that this recoil willcarry the bumper, or the door checking member, into the path of the door. To secure this result it is necessary to provide a striker, or a member which is engaged by the door and moved so as to actuate the other parts, and that said striker shall have'its door-contacting part suitably shaped and locatedso as to be engaged by the door to project the bumper into the path of the 'door. The bumper or the checking device should therefore be located outside, or :close to the edge of the door.
The herein mentioned parts of the device are further adapted for right and left side uses, by merely being separated and reversed in position, as may be required for right and left hand swinging doors.
It may be possible that some of the details of construction of this device can be modified in shade and design without changing the principles involved, and I do not therefore wish to limit my scope of invention to the exact designs herein shown, but reserve the right to use all others which may involve the same principles.
What I claim is:
