Description

F. A. ADAMS Aug. 4, 1964 DOOR STOP Filed April 15, 1964 United States Patent 3,143,369 DGGR STE)? Francis A. Adams, 3375 Brothers Place SE, Washington, D13.
Substituted for abandoned application Ser. No. 128,567, Aug. 1, 1951. This application Apr. 15, 1964, Ser. No. 360,892
1 Claim. (Cl. 292-288) The present invention relates to door stops.
An object is to provide an improved door stop that is simple in construction, readily and easily put to use, and relatively inexpensive to manufacture.
In its preferred form, the door stop is described hereinbelow and is shown in the accompanying drawing in which- FIG, 1 represents a side elevation of the door stop and shows a portion of a door to which the door stop is applied; FIG. 2 is a plan view of the bottom of the door stop; and FIG. 3 is a cross-section on line 3-3 of FIG. 2.
The door stop consists of a rod 1 which serves as a handle, a foot 4 attached to one end of the rod 1, and a pad 3 adjacent the foot 4.
The rod 1 passes through the center of the pad 3 to the foot 4 which normally rests on the floor beneath the pad 3. The rod 1 is provided with a screw thread 2 and is in screw-threaded engagement with the pad 3.
The pad 3 is made of a resilient material such as rubber. It circumscribes the rod and has an outer edge that extends completely around the rod 1, and its upper surface, as shown, is concave. Any portion of the edge is insertable in a space between the floor and the bottom edge of a door. At the edge, on the lower side of the pad, is a ridge 5 the plane of which is at right angles to the rod 1, and which tends to grip the floor when the door stop is in use.
The rod 1 is adapted to be held vertically by the pad 3.
"ice
When the pad is on the floor, the upper end of the rod is at a height substantially where it may be grasped by a person without having to bend over to reach for it.
In applying the device, the handle 1 is grasped and the edge of the pad 3 is slid into the space between the floor and the lower edge of a door while the ridge 5 remains in contact with the floor. With the door stop in this position, if the door is still movable or if it is necessary to tighten the hold on a door, the upper surface of the pad 3 can be raised and be brought into closer contact with the doors edge by turning the handle 1 in one direction. To loosen the hold on the door, the handle 1 is turned in the opposite direction, whereby the upper surface of the pad 3 is lowered and is moved away from the edge of the door.
I claim:
In a door stop consisting of a vertical rod, a foot attached to the lower end of said rod and adapted to rest on the floor, and a rubber pad through which the said rod passes, said rod being in screw-threaded engagement with said pad, said pad having an outer free edge and outer marginal area on the underside thereof that extend completely around the rod, the said marginal area of said pad being adapted to be supported on, and to be normally completely in contact with the floor, and any portion of said edge being insertable in a space between the floor and the bottom edge of a door; and the upper surface of said pad being movable into and out of contact with said edge of said door by turning the rod while said marginal area remains in contact with the floor.
