DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door stop, and more particularly, to a door stop which can be fixed in an open state or closed without being bent.

[0002]

2. Description of the Related Art Conventionally, when a door is opened, a door stop is fixed at a maximum allowable opening position of the door in order to prevent the door from being opened more than necessary and the door or knob from hitting a pillar or a wall. I have.

[0003]

In the conventional door stop, a stop ring is swingably mounted on the door stop to fix the door in an open state, and the stop ring is disposed on the door side. The hook is to be locked. For this reason, when fixing the door in the open state or closing the door fixed in the open state, each time, bend down and hook the stop ring with the hook by hand, There is a problem that the operability of the door is poor, for example, the door needs to be separated, and the door cannot be opened and closed while carrying luggage.

The present invention has been made in view of the above-mentioned problems of the conventional door stop, and provides a door stop which can fix the door in an open state or close the door fixed in an open state without bending. The purpose is to:

[0005]

In order to achieve the above object, a door stop according to the present invention provides a stopper rod on a mounting piece, and a projecting piece formed at the tip of the stopper rod can be moved in the horizontal and vertical directions. And a stopper movable body disposed so as to be biased in one direction by a spring, and a projecting piece formed at the tip of a stopper rod of the stopper movable body. And a stopper fixed body having a groove formed therein.

[0006] In this door stop, when the door is opened, a projecting piece formed at the tip of a stopper rod of a stopper movable body, which is movable in the horizontal and vertical directions and is urged in one direction by a spring, The door can be fixed in an open state by being introduced into the locking portion from the outward path of the groove formed in the stopper fixing body. Also, when the projecting piece is introduced into the locking portion of the groove formed in the stopper fixed body and the door fixed in the open state is slightly moved in the opening direction, the projecting piece is formed on the stopper fixed body. The door can be closed by being introduced into the return path from the locking portion of the groove.

In this case, a buffer member can be provided at the contact portion between the movable stopper member and the fixed stopper member.

Thus, when the door is opened, it is possible to prevent a large impact force from being applied to the protruding piece formed at the tip of the stopper rod of the stopper movable body or the groove formed in the stopper fixed body.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a door stop according to the present invention.

This door stop is composed of a movable stopper 1 attached to the door (it can be attached to the floor or a wall) and a fixed stopper 2 attached to the floor or the wall (it can also be attached to the door). Be composed.

The movable stopper 1 has a stopper rod 10 attached to a mounting piece 14, and a projecting piece 11 formed at the tip of the stopper rod 10 can be moved horizontally and vertically, and
The torsion spring 13 allows one direction in the horizontal and vertical directions (the direction of the arrow A1 in FIG. 1A and the direction of the arrow A2 in FIG. 2A).
(Direction).

In this case, the stopper rod 10 is arranged so that a through hole 16 formed at the base end of the stopper rod 10 is loosely fitted to the shaft 12 provided on the mounting piece 14. Also,
A fixing screw hole 15 is formed in the mounting piece 14.

The stopper fixing body 2 is provided on a top surface of a main body 20 formed in a cylindrical shape.
A groove 21 with a difference in height for guiding the projecting piece 11 formed at the tip of the stopper movable body 1 is formed at the tip of the stopper rod 10 of the stopper movable body 1 when the door is opened.
In order to prevent a large impact force from being applied to the groove 21 formed in the main body 20 of the stopper 1 and the stopper fixed body 2, a rubber or the like is provided at a position where the mounting piece 14 of the stopper movable body 1 abuts so as to surround the main body 20. A buffer member 22 made of an elastic body is provided.

In this case, the groove 21 formed on the upper surface of the main body 20 has an introduction / lead-out part a of the projecting piece 11, a forward path b gradually rising from the introduction / lead-out part a, and a forward end c. An engaging portion e having a forward end c and a step d, which is lower than the forward end c, a backward starting end f at the same position as the engaging portion e, a backward g gradually rising from the backward starting end f, and a backward g. h
And the introduction / lead-out part a of the projecting piece 11 lower than the return path g is formed in a loop shape by opening one end of the introduction / lead-out part a.

In this embodiment, the buffer member 22 is provided on the main body 20 of the stopper fixed body 2. However, the stopper movable body 1 in contact with the stopper fixed body 2 is provided.
The mounting piece 14 may be provided with a buffer member.

The door stop is formed at a tip end of a stopper rod 10 of the stopper movable body 1 which is movable in the horizontal and vertical directions when the door is opened, and is urged in one direction by a spring 13. The piece 11 is introduced into the introduction / lead-out part a of the groove 21 formed in the stopper fixed body 2,
When the door is released from the lead-out portion a via the outward path b and reaches the outward path end c, and the door is released in this state, the projecting piece 11 is locked at a position lower than the outward path end c, having a step d with the outward path end c. By being introduced into the part e, the door can be fixed in an open state.

When the projecting piece 11 is introduced into the locking portion e of the groove 21 formed in the stopper fixing body 2 and the door fixed in the open state is slightly moved in the opening direction, the projecting piece 11 Reaches the return path starting end f from the locking portion e,
When the door is released in this state, the return path g has a step h from the return path g through the return path g gradually rising from the return path start end f.
The door can be closed by reaching the lower introduction / lead-out part a and going out of the groove 21 from the open end of the introduction / lead-out part a.

In this case, since the projecting piece 11 is urged by the spring 13 in one of the horizontal and vertical directions,
As described above, the inside of the groove 21 can be moved in one direction without going backward.

[0019]

According to the door stop of the present invention, by simply opening and closing the door, the door can be fixed in the open state or fixed in the open state by simply opening and closing the door without bending. The door can be closed, so for example,
The door can be easily opened and closed while carrying luggage, and the operability of the door can be improved.

Further, by providing a buffer member at the contact portion between the movable stopper and the fixed stopper, when the door is opened, the projecting piece formed at the tip of the stopper rod of the movable stopper or the fixed stopper can be used. A large impact force can be prevented from being applied to the formed groove, and the durability at the door stop can be improved.
