DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF INVENTION

(18) A door stop according to a preferred embodiment of the invention is illustrated in FIGS. 1-8, and shown generally at reference numeral 10. As shown in FIGS. 1-3, the door stop 10 comprises an elongate threaded member 11 and a substantially flat and rectangular mounting panel 15. The threaded member 11 and the mounting panel 15 can be made of steel or other suitable material.

(19) The elongate threaded member 11 includes a substantially flat and circular head section 12 at one end thereof, as shown in FIGS. 1-4. The head section 12 has a diameter substantially greater than the rest of the threaded member 11. The threaded member 11 can be a flat head bolt, elevator bolt, or other suitable elongate member having threads formed thereon.

(20) A cushioning section 14 can be attached to the outer surface of the head section 12, as shown in FIGS. 1-3. The cushioning section 14 can be made of felt, polyurethane foam or other soft, non-abrasive material. The cushioning section 14 can be attached to the head section 12 by an adhesive or by other suitable attachment means.

(21) The mounting panel 15 has three round holes 21, 22, 23 formed therein and positioned linearly, as shown in FIG. 3. The center hole 22 is shaped and sized to receive the elongate portion the threaded member 11 there through, as shown in FIG. 2. The head section 12 has a substantially greater diameter than the center hole 22, thereby preventing the threaded member from moving completely through the center hole 22. A locking nut 16 can be threaded on the threaded member 11, with the mounting panel 15 intermediate the locking nut 16 and the head section 12, as shown in FIGS. 5 and 6. The locking nut 16 can be made of nylon, plastic, or other suitable material.

(22) The door stop 10 can be attached at the bottom edge 52 of a door 50, as shown in FIGS. 7 and 8. A cavity can be formed in the bottom edge 52 of the door 50 to receive a portion of the threaded member 11. The cavity can be formed using a drill or other suitable means. The distance between from the bottom edge 52 of the door and the floor can vary with various doors. The effective length of the door stop 10 can be adjusted accordingly by adjusting the position of the threaded member 11 in relation to the locking nut 16. Rotating the threaded member 11 clockwise reduces the effective length of the door stop 10, as illustrated in FIG. 5. Rotating the threaded member 11 counter-clockwise increases the effective length of the door stop 10, as illustrated in FIG. 6. When the distance from the mounting panel 15 to the cushioning section 14 is approximately equal to the distance from the bottom edge 52 of the door 50 to the floor 60, the locking pin 16 and the portion of the threaded member 11 extending above the mounting panel 15 can be positioned within the bottom edge 52 of the door 50, with the mounting panel 15 positioned flat against the bottom edge 52 of the door 50. Fastening members such as wood screws 31, 32 are positioned through the left and right side openings 21, 23 of the mounting panel 15, as shown in FIG. 1, and screwed into the bottom edge 52 of the door 50 to securely attach the door stop 10 to the door 50.

(23) With the door stop 10 secured to the bottom edge 52 of the door 50, the door stop 10 can prevent unwanted movement of the door 50. The cushioning section 14 contacts the floor 60 and provides a level of frictional engagement that keeps the door 50 in a fixed position when not being moved by a person. The cushioning section 14 provides a level of frictional engagement such that the door 50 can be opened and closed when reasonable force is applied to the door, but stops the door 50 and maintains it in a fixed position when a person is not moving the door 50. There is no risk of the door stop 10 damaging an adjacent door or wall. The soft material of the cushioning section 14 prevents the door stop 10 from scratching the floor 60.

(24) A door stop according to another preferred embodiment of the invention is illustrated in FIGS. 9-13, and shown generally at reference numeral 100. As shown in FIG. 9-11, the door stop 100 comprises a spring-loaded member 111, and an elongate rod 113 telescopically positioned within the spring-loaded member 111 adapted for sliding movement within the spring-loaded member 111. The door stop 100 can include a mounting panel 115. The spring-loaded member 111, the rod 113 and the mounting panel 115 can be made of steel or other suitable material.

(25) The spring-loaded member 111 can be comprised of a substantially hollow, cylindrical body, and a coil spring contained within the body. The housing includes a circular opening for receiving the elongate rod 113 that can be attached to the coil spring.

(26) A substantially flat and circular head section 112 is positioned at one end of the rod 113, as shown in FIGS. 9-11. The head section 112 can be attached to the rod 113 by an adhesive or other suitable attachment means. Alternatively, the head section 112 can be an integrally formed with the rod 113. The head section 112 can be made of plastic or other suitable material. A cushioning member 114 can be attached to the outer surface of the head section 112, as shown in FIGS. 9-11. The cushioning section 114 can be made of felt, polyurethane foam or other soft, non-abrasive material. The cushioning section 114 can be attached to the head section 112 by an adhesive or other suitable attachment means.

(27) The mounting panel 115 has three round holes 121, 122, 123 formed therein and positioned linearly, as shown in FIG. 10. The center hole 122 is shaped and sized to receive the rod 113 there through, as shown in FIG. 10.

(28) In a method of using the door stop 100 according to a preferred embodiment of the invention, the door stop 100 can be attached at the bottom edge 152 of a door 150 proximate the side edge 154 on which the door hinges 156 are attached, as shown in FIG. 14. If the door 150 is already hinged to the wall, then it should be removed prior to attaching the door stop 100.

(29) A cavity can be formed in the bottom edge 152 of the door 150 to receive the spring-loaded member 111 therein. The cavity can be formed using a drill or other suitable means. The spring-loaded member 111 is positioned within the cavity in the bottom edge 152 of the door 150, with the mounting panel 115 positioned flat against the bottom edge 152 of the door 150, as shown in FIG. 14. Fastening members such as screws 131, 132 are positioned through the left and right side openings 121, 123 of the mounting panel 115, and screwed into the bottom edge 152 of the door 150 to securely attach the door stop 100 to the door 50, as shown in FIG. 14.

(30) With the door stop 100 secured to the bottom edge 152 of the door 150, the door stop 100 can prevent unwanted movement of the door 150. As shown in FIG. 15, the cushioning section 114 contacts the floor 160 and provides a level of frictional engagement that keeps the door 50 in a fixed position when not being moved by a person. The cushioning section 114 provides a level of frictional engagement such that the door 150 can be opened and closed when reasonable force is applied to the door, but stops the door 50 when a person is not moving the door 150. The soft material of the cushioning section 14 prevents the door stop 100 from scratching the floor 160.

(31) The door stop 100 can be used on a floor 160 having an object thereon that is higher than the rest of the floor 160, such as a saddle or sill plate 162. When the door stop 100 is moved to the sill plate 162, the spring-loaded member 111 allows for the rod 113 to be pushed upwardly by the sill plate 162 just enough so that the sill plate 162 does not prevent further movement of the door stop 100 by the user, while maintaining contact between the cushioning section 114 of the door stop 100 and the sill plate 162, as illustrated by FIGS. 12-13 and 15-17.

(32) A door stop and a method of using same are described above. Various changes can be made to the invention without departing from its scope. The above description of various embodiments of the invention are provided for the purpose of illustration only and not limitationthe invention being defined by the claims and equivalents thereof.
