Description

[Detailed description of the invention] The present invention relates to a door check that can maintain the open state of the door, and provides a door check that has an extremely simple structure and has excellent strength. .

Conventionally, door locking devices with various structures have been devised, but many of them cannot adjust the door locking angle or have complex structures.
Furthermore, the chain type had the risk of being severed from the outside, making it incomplete in terms of crime prevention.

The inventor of the present invention conducted various improvement studies to solve the deficiencies of the conventional door locking device, and as a result, developed a hinge that has an extremely simple structure, excellent strength, and cannot be reached by hands or tools from the outside. This is a completed door check that can be installed in any direction.

That is, the present invention has a base 41 attached to a wall 1, a square steel pipe 4 bent into an arc shape, and a door 2 formed to be fitted into the square steel pipe 4.
In the door arch, which is constructed of a base 51 attached to a base 51 and an insert steel plate 5 bent into an arc shape, a shaft 7 is provided at the front end of the square steel pipe 4 for moving the shaft 7 from side to side and for locking it. recess 9
1, and a slit 9 for sliding on the shaft 7 to move from side to side is provided at the front end of the other inserting steel plate 5 and a corresponding rear end thereof. a plurality of recesses 81 that match the recesses 91 and lock the shaft 7;
82, 81', 82' are provided, and the end of the square steel pipe 4 is locked at the rear surface so that the slits 9, 8 can be moved left and right, and the recesses 91, 81, 82,
This door check is characterized in that it has a shaft 7 which can be moved by means of a handle 6 that fits into 81' and 82'.

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

The drawings show an embodiment of the door check of the present invention. Figure 1 is a plan view of the entire door check with door 2 closed, and Figure 2 is a plan view of the entire door check with door 2 closed, similar to Figure 1. Front view in condition, 3rd
The figure shows a plan view with the door 2 slightly opened and checked in this position, Figure 4 is a partial front view of the tip of the square steel pipe 4 bent into an arc shape, and Figure 5 shows the arc shape. 6 is a rear view of the partial tip of the square steel tube 4, FIG. 7 is a rear view of the partial tip of the insertion steel plate 5, and FIG. 8 is a partial front view of the tip of the square steel tube 4. It is a top view which shows the state where the insertion steel plate 5 was inserted.

As shown in Figures 1 and 3, the door check of the present invention consists of a square steel pipe 4 bent into an arc shape that is attached to a wall, and a square steel pipe 4 that is inserted into the square steel pipe and bent into an arc shape to be attached to a door. A base 41 of a rectangular steel pipe 4 bent into an arc shape is firmly attached to the wall 1.

The base 5 of the insertion steel plate 5 that is inserted into the square steel pipe 4
1 is firmly attached to the door 2.

The curvature of each bending process is adjusted so that the inserted steel plate 5 slides inside the square steel pipe 4 as the door 2 is opened and closed.

As shown in FIG. 4, a slit 9 and a recess 91 are provided at the front end of the square steel pipe 4.

The inserted steel plate 5 is inserted into the square steel pipe 4 as shown in FIG.
It is designed to be inserted and slid into the fifth
As shown in FIG. 7 and FIG. 7, the front end portion and the corresponding rear end portion have a slit 8 communicating from the front portion to the rear portion for sliding on the shaft 7 and moving from side to side, and the recessed portion. Matches 91,
A plurality of recesses 81, 82, 81' communicating from the front part to the rear part for locking the shaft 7,
82' is provided.

Further, if necessary, recesses 81' and 82' may be provided at the positions indicated by the dotted lines in FIGS. , 82' may be increased and provided at appropriate positions.

One end of the shaft 7 is movably locked to the rear end of the square steel pipe 4 by a stopper 10, and is inserted through the slits 9 and 8, and is inserted into the slit 9 by the handle 6.
It is loosely attached to the front part of the square steel pipe 4 so that it can be moved to the recess 91.

Therefore, when the shaft 7 is held in the slit 9 by holding the handle 6, the door 2 can be opened and closed.

Position the shaft 7 in the recess 91 and open the door 2.
When opened, the recess 91 and the recess 81 of the inserted steel plate 5
At the point where the shaft 7 matches the recess 91 and the recess 81
In this position, the door 2 is checked.

When closing the door 2 again, the shaft 7 only needs to be returned to its original position.

Since the present invention has the above-described configuration, it is attached to the hinge 3 side, and hands and tools cannot reach it from the outside, which is preferable for crime prevention. Furthermore, since the inserted steel plate slides within the square steel pipe, it has superior strength and is simpler in structure than the conventional crank-shaped connecting arm type.

There is no need to attach or remove the chain as in the chain type. Further, according to the structure of this invention, if it is desired to lock the door in any open state, this can be done by appropriately providing a recess in the insertion steel plate.
