Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial field of application >> The present invention is directed to a central portion which is a butted portion of the doors, in which the symmetrical ends of the two doors in the width direction are pivotally attached to the door mounting member. Therefore, the present invention relates to an improvement of a door closing device in a double door that opens each door to the left and right.

<< Prior Art >> Conventionally, as a door closing device of this type, ones shown in FIGS. 5 and 6 are known.

That is, a locking lever c having a locking portion d formed at one end is rotatably attached to a main body b fixed to the inner surface on the open end side of one door a, and an operating portion e at the other end is a door mounting member. An elastic force is exerted by a spring h so as to be projected and held from the opening f ′ of f toward the other door g side, and is pivotally supported by a vertical support shaft h to close one door a and then the other. When the door g is closed, the operating portion e of the locking lever c is pushed by the inner surface of the door g, and when the closing of the door g is completed, the locking lever c is the center of the support shaft h. As a result of being rotated counterclockwise around the rotation center i against the spring force, the locking portion d of the locking lever c is fixed to the bottom plate j of the door mounting member f or the like. The door a is configured to be closed as shown in FIG.

<< Problems to be Solved by the Invention >> However, in the above conventional device, the locking lever c is used.
Since the operation part e and the locking part d are integrally formed, in order to hang the locking part d from the receiving metal fitting k, it is necessary to rotate the locking lever c to the expansion angle α. , Both doors a, g
When a force in the opening direction is applied to one of the doors a with the door closed, the force is applied to the locking lever c in the direction in which the locking part d is disengaged by the receiving metal fitting (the direction of the arrow in FIG. 6). The door opening force acts on the door g via the operation portion e, and the doors a and g are likely to be opened.

Therefore, in order to obtain a door closing force sufficient to oppose the opening operation of the one door a by the catch (not shown) of the other door g with respect to the door a, it is necessary to increase the length of the operating portion e by the principle of leverage. In order to prevent the door a from being opened even when the door a is opened, the operation portion e causes the door mounting member f as shown in FIG. 5 to open when the door a is opened. Since it protrudes to the outside from the opening f ′ for a long time, the appearance is not only bad, but when it is used for western clothes etc., it is easy to hook it on the operation part e when putting in and taking out clothes. There is a problem that the pressing movement stroke l of the operation part e by the door g becomes long, the closing operation of the door g is heavy, and the operability is poor.

The present invention has been made in view of the above problems of the above-described conventional technique, and has a configuration in which a locking lever and an operating lever are separately formed, and these are appropriately pivotally supported with respect to a main body. By doing so, the door to which the device is fixed can be surely kept in the closed state against the opening force, and the closing operation of the other door can be smoothly performed.
Moreover, the purpose is to be able to perform with good operability.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a double door having a front outer end screwed to left and right side plates of a door mounting member to achieve the above object. The main body is attached to the upper or lower part of the inner surface of the butt end side of one of the doors, and the receiving metal fitting is attached to the inner surface of the top plate or the bottom plate of the door mounting member corresponding to the main body. , A locking lever having a locking portion at the front end and an operating portion at the rear end is rotatable up and down so that the locking portion can be hung and disengaged from the receiving metal, and is disengaged by a spring. The operation lever for the locking lever is pivotally supported in the direction of being held in the stopped state, and the locking lever can be rotated by the rotation thereof against the elastic force of the spring. One end contacts the inner surface of the operating part, and the other end closes the other door. An object of the present invention is to provide a door closing device which is pivotally supported so as to project to a position where it is pushed by the closing.

<< Operation >> Of the two double doors, the main body is fixed to the upper or lower part of the inner surface of the butt end side of one of the doors with a screw or the like, and the operation lever is projected to the other door side.

On the other hand, on the top plate or bottom plate of the door mounting member,
It is fixed with a screw or the like corresponding to the locking lever of the main body.

Therefore, when one of the doors is closed and then the other is closed, the inner surface of the butt end side of the door abuts against the operation lever. Since the one end of the locking lever pushes the actuating part at the rear end of the locking lever, the locking lever rotates around the support shaft against the spring force, and the locking part at the front end is rotated. Is locked to the receiving metal fitting, and one door is securely closed to the door mounting member.

Further, since the other door is closed by the one door by a catch or the like, both doors are held in the closed state.

In such a closed state, when the other door is opened against the closing force of the catch, the pressing force of the operating lever by the door is released, so the locking lever is biased by the spring for urging the locking lever. However, since it is rotated in the opposite direction to the above, the locking with the receiving fitting is released at the same time, and at the same time, the operating lever is also returned to rotate in the opposite direction via the actuating portion.

Therefore, one door can be opened next to the other door.

<< Embodiment >> The present invention will be described below with reference to an illustrated embodiment.

As shown in FIG. 1 to FIG. 4, the main body 1 integrally formed of metal or synthetic resin has a recessed portion 2 which is open at the front end and is formed in the central portion on the back surface side.
Recessed groove portions 3, 3 communicating with the recessed portion 2 are provided on the rear surface side and are opposed to both left and right side portions.

A plate-shaped back lid 4 is fixed to the back surface of the main body 1 by screws 5, and the back lid 4 closes the lower end openings of the recessed portions 2 and the both recessed groove portions 3, 3.

The locking lever 6 is integrally formed of a strip-shaped metal plate or the like, and a locking portion 7 is formed at the front end and an operating portion 8 is formed at the rear end by bending downward. .

The locking lever 5 has brackets 9 and 9 which are bent downward and are provided on both left and right sides in the width direction near the rear end of the locking lever 5 by means of a support shaft 10 penetratingly supported by the main body 1 in the left and right direction. , In the recessed portion 2, the front end portion and the rear end portion are axially supported so as to be vertically rotatable, and the front end portion thereof is
That is, the locking portion 7 projects forward from the front end opening 2a of the recess 2 by a required length.

A compression spring 11 is provided between the rear surface of the operating portion 8 of the locking lever 6 and the rear wall 2b of the recess 2 of the main body 1, and the elastic force of the compression spring 11 causes the locking lever 6 to move. , The horizontal state as shown in FIG. 2 or the operating portion 8 is held in a slightly lowered state.

The operation lever 12 with respect to the locking lever 6 has a pressing portion for the locking lever 6, which is bent at one end side thereof into a substantially L-shaped plane.
In addition to having 13, an operating portion 14 is formed at the other end, which is pushed by a closing door described later.

The operation lever 12 is inserted into any one of the concave groove portions 3 of the main body 1 so that the curved portion 12a, which is the base end side of the pressing portion 13, is attached to the main body 1 and the back cover. 4 is rotatably supported by a vertical support shaft 15 penetratingly supported by 4 and its pressing portion 13 is in contact with the front surface of the operating portion 8 of the locking lever 6, and the operating portion 14 is the main body. 1 is projected obliquely rearward from one side, and thus, when the operation lever 12 is rotated in the counterclockwise direction in FIG. The actuating portion 8 of the stop lever 6 is pushed and rotated rearward against the elastic force of the spring 11.

Here, the operation lever 12 is selected and attached to any one of the concave groove portions 3, 3 according to the usability of the door closing device.

Further, the receiving metal fitting 16 with which the locking lever 6 is locked has a vertical locking surface 17 facing forward from the upper surface thereof.
A locking portion 17 having a is projectingly provided, and a mounting hole 18 which is long in the front-rear direction is provided so as to allow the mounting position thereof to be adjusted in the front-rear direction.

If the usage of the door closing device constructed as described above is explained, as shown in FIG.
0,20, two doors 21,22 are pivotally attached to the front edge by hinges 23,24 at the outer ends in the lateral width direction, whereby the opening 19a of the door mounting member 19 is Although it can be opened and closed by the doors 21 and 22, the main body 1 is fixed to the lower end of the inner surface of the door 21 on the butt end side in the illustrated example with screws 25, and the operating portion 14 of the operating lever 12 is opened as described above. It is made to project to the portion 19a side.

On the other hand, the receiving metal fitting 16 is at a position where the locking portion 7 of the locking lever 6 is locked to the locking portion 17, and the bottom plate 19b of the door mounting member 19 is provided.
It is fixed on the inner surface by screws 26.

Then, when one of the doors 21 is closed and then the other door 22 is closed, the operating portion 14 is pushed by the inner surface of the butting end side thereof, whereby the locking lever 6 moves around the support shaft 15 as the center.
As shown in FIG. 2 and FIG. 4, the locking lever 6 is rotated in the direction of arrow A, and the operating portion 8 of the locking lever 6 is pressed rearward by the pressing portion 13 at the inner end thereof, so that the locking lever 6 is moved to the direction shown in FIG. From the position shown in Fig. 3 to the position shown in Fig. 3 against the elastic force of the spring 11.
It rotates about 10, and the locking portion 7 at the tip is locked by the locking portion 17 of the receiving metal fitting 16, and the closing of the door 21 is ensured. At this time, the other door 22 is The door 21 is held closed by a catch (not shown) attached to the abutting end face with the door 21.

Therefore, the one door 21 is not opened prior to the other door 22, and the other door 22 is opened, so that the operation lever is opened.
12 and the locking lever 6 is returned to its original position by the spring 11 and the door 21 cannot be opened unless the locking lever 6 and the metal fitting 16 are unlocked. .

<Effect of the Invention> Since the present invention is configured as described above, even if an opening force is applied to the door to which the device is attached with both doors closed, this force is The locking lever does not act in the direction in which it disengages from these receiving fittings, but it acts in the direction in which it engages with the receiving fitting, so that the door can be closed securely, and the locking lever formed as a separate member. The operating lever is also configured such that the vicinity of the rear end of the locking lever is pivotally supported on the main body by a support shaft and the inner surface of the operating portion provided at the rear end is pressed by one end of the operating lever. Since the lever is rotated, the locking portion side of the locking lever can be largely rotated in the vertical direction by only slightly rotating the operation lever, and thus the locking area with the bracket can be increased. Since it is possible to shorten the operating lever Therefore, since the operation lever does not project to the opening side of the door mounting member for a long time, the appearance is excellent, and the operation stroke of the operation lever by the other door is reduced, so that the door is closed. The load on the door is reduced and the operability of closing the door is improved.
