Description

[Detailed Description of the Invention] The present invention relates to a door locking device for maintaining the open position of a gate that rotates to open and close using a pivot on one side when the gate is opened.

Conventionally, in order to keep this type of door closed, various types of bolts, hooks, locks, etc. have been used between the door rotation end and its receiving side depending on the purpose. However, most of them are configured in a so-called free state without any means of holding the door open when it is opened, and when it is necessary to hold the door open, a wire is used. It was customary to bend the tip of a door into a hook shape, fix the other end to a building, etc., and hang the hook-shaped portion on a door frame to keep the door open. Also, recently, there have been some products that have a simple door closing prevention mechanism attached to the pivot part of the door so that the user can lock and unlock the door with the required force. Since the door is cantilevered, there are problems with the durability of the rotating shaft under load, and the structure tends to be complicated, which is a problem from the practical standpoint of the door.

This project was devised in view of the above-mentioned points of conventional gates, and is made completely separate from the door structure so that unnecessary structural loads are not applied to opening and closing the door, and the door can be held open and released easily and reliably. It is an object of the present invention to provide a gate latching device that can be used in various ways.

Embodiments of the present invention will be described below based on the drawings.

Figures 1 and 2 show an assembled view and an exploded view of the main parts of the gate locking device A according to the present invention, and Figure 3 shows a usage state of the device.
is a pillar of a required length, and a pillar fixing part 2 is formed as a screw in this embodiment at the lower part of the pillar for embedding or attaching the pillar to a support base such as the ground or concrete ground. Therefore, the column 1 in this case is a column holder (not shown) disposed on the support base.
It will be screwed into place. 3 is a positioning member that rotatably supports one end of a latching tool 4 for latching the gate B when required, and is loosely fitted onto the support post 1 so that it can be fixed at an appropriate height with a set screw 5 on the side. ing. 4 is a hook for hanging the gate B when necessary as described above, and is a hook for hanging the stile of the gate B as shown in Fig. 3, which is made by bending the tip of a very thick wire into a substantially L shape. In this embodiment, the attachment part to the positioning member 3 is used as a support shaft 4b to be freely rotatable in the vertical direction so that the lower stile of the gate can be attached and detached. Reference numeral 6 denotes a buffer material such as rubber or resin material that is fixed to the upper part of the support column 1 with fixing screws 7. When installed, it is placed opposite the stile of the gate B, and when the gate is operated, the support 1 of the stile is
This is to reduce the impact caused by collision with the

In the structure as described above, first, the positioning member 3 is fitted into the support 1, and the positioning member 3 is temporarily fixed or allowed to slide freely using the fixing screw 5 at an appropriate intermediate position of the support. Thus, the shock absorber 6 is fixed to the upper part of the support column 1, and is fixed to the support column with the leg length fixing screw 7. Gate hanging device A assembled in this way
is fixed to a support base near the opening position of the gate B, as shown in FIG. 3, so that the buffer body 6 is located at a height opposite to the lower stile of the gate. For this fixation, it is preferable to bury one end of the support column 1 in the base surface in view of the durability of the latching device A, but it is also possible to separately arrange a support column holder at this position and attach it to the holder. After the support 1 is thus fixed to the base surface, the positioning member 3 is slid upward,
The hook portion 4a of the supporting hook 4 is fixed to the pillar 1 with a stopper screw 5 at a position where it can be hooked to the lower stile of the gate B. Note that, depending on the installation height position of the gate, the buffer body 6 and the lower stile of the gate B may not always come into contact with each other. In other words, if the buffer body 6 is higher than the lower stile position of gate B, it is sufficient to fix the support 1 deeply to the base surface, but if the buffer body 6 is lower than the lower stile position of gate B, it is difficult to make them contact each other. It is. Therefore, as shown in Fig. 4, the length H of the buffer body 6 is made larger than the width of the lower stile of the gate, and a cavity 6a with an inner diameter approximately equal to the outer diameter of the support column 1 is bored from below inside the buffer body. A fixing screw 7 of a different length is placed, and a filling material 6b is put into the cavity to obtain the required height, and then the support 1 is inserted into the cavity. After that, if the screws 7 are tightened and fixed, the lower stile of the gate B will be attached to the buffer body 6.
The two can be brought into contact with each other in an appropriate positional relationship without passing over the top of the.

In such an installation situation, when holding the gate in the open position, open the door to the vicinity of the buffer body 6 of the latching device A, or bring the lower stile of the door into contact with the buffer body, Next, the hook part 4a is engaged with the lower stile by rotating the hook 4 as shown in FIG.
Hold the gate B.

To release the latching, it is sufficient to rotate the latching tool 4 in the opposite direction to the latching operation, and the latching and unlatching can be done with a simple operation.

Incidentally, in the above embodiment, an example in which the gate is hung on the lower stile of the gate door has been described, but it may be hung on the vertical stile that is the side frame. This purpose can be achieved by horizontally attaching it to a separately formed upright base or the like. In addition to rotatably supporting the latching tool 4 relative to the positioning member 3, it is also possible to always bias it in the latching direction by using a spring.

As mentioned above, the present proposal is to hold and hold a gate in the open position that rotates to open and close with one side as a pivot, and includes a support that fixes one end to a foundation surface such as the ground, and a support that is fixed to the support. The gate sill is made up of a shock absorber that cushions the impact of the gate stile, and a hook having a hook portion that latches the stile, and is installed on the base surface near the opening position of the gate. The gate door itself can be installed without any structural load, and the structure of the door as a whole can be simplified, which can have a favorable effect on durability. Furthermore, since the shock absorber is placed over the upper end of the column and fixed using a filler and a fixing screw, the structure can be simplified compared to a structure in which it is fixed using a fixing flange or the like provided on the column.
Furthermore, the height of the buffer can be adjusted by changing the amount of filling material, and the height of the hanging tool can be adjusted by moving the positioning material. It can be fixed without paying too much attention to its positional relationship. the result,
It is possible to provide a gate latching device that can be easily installed on existing gates, contributes to construction efficiency at construction sites, and has various practical effects.
