Abstract

A locking door stop includes a fixing seat, a catch rod, a locking plate, and an anti-skid pad. Thus, the anti-skid pad is freely rotatable relative to the catch rod to fit the inclined angle of the ground so that the door stop has an automatic angle adjustment function so as to fit the inclined angle of the ground. In addition, the spring is compressed during movement of the resting portion of the catch rod to produce an elastic compensation effect to the anti-skid pad, so that the anti-skid pad is positioned on the ground solidly and stably.

Claims

1. A door stop, comprising a fixing seat, a catch rod, and an anti-skid pad, wherein:

the fixing seat has an inside formed with a receiving recess having a top face formed with a top through hole and a bottom face formed with a bottom through hole;

the catch rod is slidable through the receiving recess of the fixing seat and has a top end protruded outward from the top through hole of the fixing seat and formed with an enlarged pedal and a bottom end protruded outward from the bottom through hole of the fixing seat and formed with a resting portion and an annular retaining groove for retaining a limit ring;

the anti-skid pad is mounted on the catch rod to move therewith and is rotatable relative to the bottom end of the catch rod to adjust an angle between the anti-skid pad and the catch rod.

2. The door stop in accordance with claim 1, wherein the resting portion of the catch rod is substantially arc-shaped.

3. The door stop in accordance with claim 1, wherein the limit ring is substantially C-shaped.

4. The door stop in accordance with claim 1, wherein the catch rod has a mediate portion formed with an annular snapping groove for mounting a substantially C-shaped snap ring, and the door stop further comprises a compression spring mounted on the catch rod and pressed between the bottom face of the receiving recess of the fixing seat and the snap ring.

5. The door stop in accordance with claim 1, wherein the anti-skid pad is rotatable mounted on the catch rod.

6. The door stop in accordance with claim 1, wherein the anti-skid pad includes a pad body, an adjusting member and a spring;

the pad body is mounted on the bottom end of the catch rod and has an inside having a top end formed with a mounting hole mounted on the bottom end of the catch rod, a mediate portion formed with a stepped chamber connected to the mounting hole to allow movement of the resting portion of the catch rod and to limit the limit ring of the catch rod, and a bottom end formed with a passage connected to the stepped chamber;

the adjusting member is secured in the stepped chamber of the pad body and is directed toward the resting portion of the catch rod;

the spring is pressed between the limit ring of the catch rod and the adjusting member to push the resting portion of the catch rod to move away from the adjusting recess of the adjusting member.

7. The door stop in accordance with claim 6, wherein the mounting hole of the pad body has a tapered shape.

8. The door stop in accordance with claim 6, wherein the mounting hole of the pad body has a diameter greater than that of the catch rod so that a gap is defined between the mounting hole of the pad body and the catch rod.

9. The door stop in accordance with claim 6, wherein the stepped chamber of the pad body has a top portion having a diameter grater than that of the mounting hole and a bottom portion having a diameter grater than that of the top portion.

10. The door stop in accordance with claim 9, wherein the adjusting member is secured in the bottom portion of the stepped chamber of the pad body.

11. The door stop in accordance with claim 9, wherein the limit ring of the catch rod is movable in and limited by the top portion of the stepped chamber of the pad body to prevent the catch rod from being detached from the pad body of the anti-skid pad.

12. The door stop in accordance with claim 9, wherein the bottom portion of the stepped chamber of the pad body has an end face formed with a substantially arc-shaped stop flange, and the adjusting member has a top portion formed with a substantially arc-shaped adjusting recess directed toward the resting portion of the catch rod to pivotally receive the resting portion of the catch rod and a bottom portion having a periphery formed with a substantially arc-shaped resting flange rested on and locked by the stop flange of the stepped chamber of the pad body.

13. The door stop in accordance with claim 6, wherein the adjusting member has a stepped shape.

14. The door stop in accordance with claim 6, wherein the passage of the pad body has an end face formed with a substantially arc-shaped guide face.

15. The door stop in accordance with claim 6, wherein the adjusting member is forcibly fitted through the passage of the pad body into the stepped chamber of the pad body.

16. The door stop in accordance with claim 6, wherein the spring is forcibly fitted through the passage of the pad body into the stepped chamber of the pad body.

17. The door stop in accordance with claim 12, wherein the spring has a top end mounted on the resting portion of the catch rod and a bottom end mounted on the top portion of the adjusting member.

18. The door stop in accordance with claim 6, wherein the resting portion of the catch rod is movable in the stepped chamber of the pad body toward the adjusting member until the resting portion of the catch rod is received in the adjusting recess of the adjusting member.

19. The door stop in accordance with claim 18, wherein the spring is compressed during movement of the resting portion of the catch rod to produce an elastic compensation effect to the anti-skid pad.

20. The door stop in accordance with claim 12, wherein when the resting portion of the catch rod is rested on the adjusting member, the resting portion of the catch rod is rotatable in the adjusting recess of the adjusting member so that the anti-skid pad is rotatable relative to the catch rod by a gap defined between the mounting hole of the pad body and the catch rod so as to adjust the angle between the anti-skid pad and the catch rod.
