1949. f B. E. FlSHER 2,462,174v

OOOOOO OP Patented Feb. 22, 1949 UNITED STATES TiENT t FFECE This invention relates generally to bumpers and moreparticularly to door stops.

.In the past'the type of .door-stop used in homes and other buildings usually consisted of a metallicextension member or rod having a wood screw thread 'formed on oneend thereof to secure'the stop to a wooden baseboardor in some cases to therdoor, the other end of the'rod usually being covereclsby a rubber bumper tip. This type of door stop performed its intended function successfully, namely preventing thedoor from hittingthe baseboardor wall, but is objectionable in other respects. For example, these rigid door stops are quite frequently struck or hit sideways by passing objects or people with th'eresult that the threaded end of the stop becomes loosened in the baseboard or in the door. Consequently, from time to time it becomes necessaryto refill theseienlarged screw holes or to screw the stop into the baseboard or door in a new location,

which is of course objectionable.

Accordingly, it is an object of the present invention to provides. new and improved doorstop in which the above mentioned objections are obviated.

More specifically, it is an object of thepresent invention to provide a laterally movable or flexible door stop which will flex if struck sideways without transmission of the force to the door and/or to thebaseboard on which the stop may be mounted.

Another object of theinvention is to provide a laterally movable stop which will always return tozits normal position.

Another object of the invention resides in the novel arrangement and connection' between the parts to insure-centering of the stop member, to support the stop member and to hold a cap over the outer end of the holding screw.

. A further object of theinvention is to provide a stop of the above mentioned character which will be inexpensive to manufacture.

A still further object of the invention is to providedaterally swingable door stop which may be heid bytensioned, slip-on attaching means to a door.

' Other .olojectsof .the invention will become apparent from the following detailed description taken in connection with the accompanying drawing in which:

Figure 1 is a sectional view taken longitudinally of a door stop member embodying features of the present invention.

Figure 2 is a view in elevation of the door stop, taken along the line 22 of Figure 1.

5 Claims. (01. 16-8 6 :Figure3 is asectional view taken longitudl nally of a modifiedform of my doorstop.

Figure-eds a viewin elevation of the door stop taken-along the lined-t of Figure 3 and figure 5 is a fragmentary elevational view of thadoorstop of Figure 3 looking in the direction of'thearrows 5-5 of Figure'3. Heferring to the drawing and first to Figures land 2, the door stop shown may be secured to a mounting H? which maybe a door ormay be the baseboard of a room, as desired. The door stop comprises in general, 'a supporting member or screw is! and a door'stopmember I2. The door stop-member i2 is carried or is supported by the screw -.!=l,-extending therefrom for abutment with the dooror baseboard, as the case may be. The

screw ll comprises a threaded portion 13, a second threaded portion i l and an intermediate head 15. The threaded screw portions l3, [4 are integral with the intermediate head I 5 extending respectively from opposite sides thereof. As shown in the drawing, the threaded portion I3 may have-awooclscrew thread and be screwed into the wooden mounting l0 until the head l5 abuts thereagainst.

The stop member 1-2 is an elongated, laterally movable or flexible member which will yield sides without transmitting the force of such movement to its supporting screw ll. To this end,, I prefer to use a helical coil of wire in the form-10f .a coil spring and to use a coil having abutting convolutions to provide a so called solid member longitudinally thereof. One end of the coil or stop member I2 is tapered, as at I6, and threads onto the threaded screw portion l4, thus attaching the coiled stop member l2 to its support -.or screw it. Preferably, a bumper tip I! is provided and. fits over the other end of the coiled stop member I.2,'the tip it being made of a suitable resilientmateriaLsuch as rubber.

A bell like cap it fits over and surrounds the screw .head i5, threaded screw portion l4 and an portion of the coiled stop member l2, the large end of the cap seating against the side of the door oil-baseboard it, as the case may be. At the other or outer end of the cap l8 there is an opening it where the metal is reversely bent inwardly providing a conical seat 2i converging or tapering inwardly of the cap 18. The tapered end portion l t of the coiled stop member l2 seats and wedges tightly in and against the conical seat 2| when the coiled stop member I2 is threaded onto the screw portion It and tightened down. This conical seat 2! for the coiled stop member l2 acts to center it or to-normally hold the member [2 such that its longitudinal axis will be at right angles to the surface against which the bumper is to hit. In other words, the conical seat 2| corrects the tendency of the coiled stop member I2 to extend at an angle normal to the pitch angle of the threaded portion I4. It will also be seen that threading of the tapered end of the coiled stop member I2 onto the threaded screw portion I4 against the conical seat 2| serves as the sole means for holding the cap I8 in place against the mounting I thus, eliminating need for screws or other fastening means holding the cap in place.

In the modification of Figures 3, 4 and 5, there is a door 22 on which the coiled door stop member I2 is mounted by means of a supporting member 23. This supporting member 23 is preferably made of a strip of spring sheet metal bent in a general U-shape having a leg 24, a leg or spring clip portion 25 and a joining base portion 26. As shown, the supporting member 23 slips on the bottom of the door with the base 26 against the lower door edge, the leg 24 fiat against one side of the door and the leg 25 flat against the other side thereof. The supporting member 23 is frictionally held to the door by the tensional force exerted by the clip portion or leg 25.

Formed out of the leg 24, a supporting boss 21 for the stop member l2, preferably of conical form has an opening 28 in its outer end where the metal is reverselybent inwardly of the cap, providing a conical seat 29 for the tapered end ofthe stop member I2. At its inner edge, the conical seat 29 is provided with an inturned, continuous flange 30 for attaching the tapered end'of the stop member I2 to its support 23. As shown in the drawing, the tapered end of the coil or stop member I2 is attached to the outer end of the supporting boss by placing the terminal end of the coil through the opening 28 behind the flange 30 and then turning the stop member I2 until one or more of its coils lodge behind the flange 30 in the boss 23. In this way the stop member or coil I2 is held and supported by the supporting member 23 without need of separate or additional attaching means.

From the above description it will be appreciated that in either form of the invention, the stop member by reason of being laterally yieldable will not transmit a laterally directed force thereagainst to its support with the result that the stop member supports will not be loosened. In the form of door stop of Figure 1, the conical seat of the cap serves to center the coil stop member which in turn forced against the conical seat to transmit laterally directed forces thereagainst to the stop member support, is attached directly to its support without need of separate attaching means.

It will be understood that various forms of the invention other than those described above may be used without departing from the spirit or scope of the invention. Accordingly, the invention is to be limited only as indicated by the scope of the appended claims.

Having thus described the various features of my invention, what I claim as new and desire to secure by Letters Patent is:

1. A door stop comprising, a supporting member having a threaded portion, a cap member over the threaded portion of said supporting member, said cap having a conical opening converging inwardly thereof surrounding the threaded portion of said supporting member, a coil spring having an outer bumper end, said coil spring having an inner tapered end portion seating in the conical seat of said cap member and threadedly connected to the threaded portion of said supporting member.

2. A door stop for supporting on a mounting comprising, a support having a threaded portion to screw into the mounting and having a second threaded portion to extend from the mounting, a cap member over the second threaded portion to seat against the mounting, said cap having a conical openingsubstantially co-axial with the second threaded portion and tapering inwardly of the cap, a coil spring having a tapered end portion seating in the conical opening of said cap and threaded onto the second threaded portion for solely holding the cap to the mounting and for centering the spring, and a bumper tip on the outer end of the coil spring.

3. A door stop comprising, a supporting member for attachment to a wall, a socket member surrounding said supporting member and adapted to engage the wall, and a helical coil stop member attached to said supporting member in said socket member and urging the latter against the wall.

4. A-door stop comprising, a supporting member having an outer'threaded shank portion, a cap member surrounding said threaded shank portion having an outwardly facing conical socket and a laterally flexible coiled bumper member having a conical end threaded onto said shank portion in said com'cal socket.
