DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door opening / closing device for opening / closing a door provided on furniture, fittings and the like.

[0002]

2. Description of the Related Art This door opening / closing device is provided on furniture, fittings and the like, and is an indispensable device which is attached to a fixing member such as furniture and a door to open and close the door freely.
Such an apparatus includes a first engagement member fixed to a fixing member, a second engagement member fixed to a door body, and a component (attachment member) attached to these members. The member and the second engaging member are connected to each other via the attached member, and the members can cooperate to freely open and close the door. Then, the first engagement member and the second engagement member are positioned and fixed to the fixing member and the door body, respectively, so that the door body can be freely and smoothly opened and closed. The engagement member and the second engagement member are both fixed to the fixed member and the door body as a set, and the two sets are fixed to the fixed member and the door body at predetermined intervals. It is common. However, even if they are positioned and fixed, the door body may not be properly installed on the fixing member at the time of installation. Therefore, it is necessary to adjust this.

In such an adjustment, when the surface of the fixed member to which the first engagement member is fixed and the surface of the door body to which the second engagement member is fixed overlap, if both surfaces do not overlap well. Next, a conventional adjusting method will be described with reference to FIGS. The first engaging member 101 of the door opening and closing device 100 and the second engaging member 102 thereof are fixed members 1
03 and the door body 104, respectively.
Mounting plate 105 of engaging member 101 and engaging member 102
Mounting plate 106, these plates 105,
The pivot shaft 107 and the like are attached to each other via an attached member such as a pivot shaft 107. Then, when the surface of the fixing member 103 to which the engaging member 101 is fixed and the surface of the door body 104 to which the engaging member 102 is fixed overlap, the two members are erected so that both surfaces overlap well. However, there are cases where they do not overlap well during installation. In this case, the adjustment is made by loosening the fixing screw 108 of the mounting plate 105 and rotating the adjusting bolt 109 with a screwdriver or the like. . That is, as shown in FIG. 6, the fixed shaft 110 erected on the mounting body 101a of the engaging member 101 is loosely inserted into the small hole of the projecting piece 105a projecting from the end of the plate 105, The plate 105 can be moved around the fixed shaft 110 in the direction of the arrow (the direction of the arrow in the figure is referred to as the left-right direction).
09 is screwed to the mounting body 101a, and a predetermined portion of the plate 105 is clamped at the lower part of the neck, so that the bolt 109 and the bolt 109 are clamped corresponding to the turning operation of the bolt 109. Plate 105
Is moved forward and backward, and the other end of the plate 105, that is, the cylindrical body 1 described later, is
05b can be moved in the left-right direction, and can be adjusted so that the above-mentioned both sides are overlapped well.

Next, a description will be given of a conventional adjusting method for adjusting the door body with respect to the fixing member in the direction of the arrow (the direction of the arrow in FIG. 5 is referred to as the vertical direction). As described above, the mounting plate 105 of the first engaging member 101 and the mounting plate 106 of the engaging member 102 are connected to the pivot shaft 10.
7, and more specifically, cylindrical bodies 105b and 106a formed at the ends of the plates 105 and 106, respectively, are connected in series as shown in FIG. The pivot shaft 107 is fixed, and the taper axis of the pivot shaft 107 is
The plates 105 and 106 are engaged with each other by fitting them into the tapered holes of the tapered receiver 111 accommodated in a and abutting the tapered shaft end to the tapered hole bottom. When the adjustment bolt 112 disposed in the cylindrical body 106a advances and retreats via the adjustment nut 113 fixed in the cylindrical body 106a, the tapered receiver 111 fixed to the screw shaft end of the adjustment bolt 112 Move up and down. However, since this movement is prevented by the pivot shaft 107, the plate 106 moves in the vertical direction with respect to the plate 105, so that adjustment in this direction is possible.

[0005]

However, in the conventional apparatus for performing such adjustment, due to the structural problem, once the adjustment is performed, the two surfaces do not overlap one another after a while, and the adjustment is performed again. It had a problem that it had to be re-adjusted or that it took time to make adjustments. That is, when adjusting so that the surface of the fixing member 103 and the surface of the door body 104 overlap with each other, if a load in the left and right direction is applied to the plate 105 in the structure of the conventional device, the load is adjusted by the adjusting bolt 10.
9 itself, so that the bolt 109
It is susceptible to looseness of the screw and play of the screw, etc., and it is necessary to readjust it. In addition, the load acting on the adjustment bolt is a so-called cantilever load for the bolt 109. In addition, there is a problem that the above-mentioned loosening of the bolt 109 is easily induced and the readjustment must be performed frequently. In addition, when the door is vertically adjusted with respect to the fixing member, the structure of the conventional device is such that the adjustment bolt 112 is disposed in the cylindrical body 106a. In order to make the rotation, the driver must be inserted straight into the cylindrical body 106a, and depending on the place where such a device is attached, this is difficult and takes a lot of time for adjustment.

SUMMARY OF THE INVENTION It is an object of the present invention to adjust the installation of a door with respect to a fixing member, and it is not necessary to readjust once after adjusting.
No, and the adjustment in the front-back direction is independent of the adjustment in the left-right direction
It is an object of the present invention to provide a door opening / closing device that can be operated in a simple manner. Another object of the present invention is to provide a door opening / closing device that does not require much time for adjustment when the door is mounted on the fixing member.

[0007]

In order to solve the above-mentioned problems, a door opening and closing device according to the present invention comprises a first opening and closing device fixed to a fixing member.
An engaging member, and a second engaging member fixed to the door body, wherein the first engaging member is a case body and an adjusting plate.
Equipped with a mounting body consisting of
Of these, the case is fixed to the fixing member,
To the case body, and the front and rear of the door body to the fixing member.
It is arranged movably in the direction so that the direction can be adjusted,
Furthermore, the adjusting plate, the load in the left-right direction from the second engaging member relative to the mounting plate is applied, the support provided for supporting the load, for example, uniformly dispersed, further
In addition, the adjusting plate is provided with a fitting portion with which adjusting means for adjusting the door body in the left-right direction with respect to the fixing member is engaged. In this way, the adjustment can be performed, and after the adjustment, the mounting plate is fixed to the mounting body by a fixing means, for example, a fixing bolt. Accordingly, even when a load is applied to the mounting plate in the left-right direction when the door body is adjusted in the left-right direction with respect to the fixing member, the load is evenly dispersed and supported by the support instead of the adjusting means. Due to the structure, the adjusting means does not loosen or set, so that there is no problem that the two sides do not overlap well and the re-adjustment must be performed frequently as in the related art. Moreover, this device
With the support evenly distributed and supported by the support
Independent adjustment of the front and rear direction without moving the
The door can be adjusted with respect to the fixed member.
At the time of the rebuilding adjustment, adjustments in that direction are also made.
It has the advantages of By the way, the mounting body and the mounting plate may be provided on the second engaging member instead of the first engaging member, and may be provided on both the engaging members as the case may be. Needless to say.

[0008] It is a matter of course that the support can support the load applied from the mounting plate in any of the left and right directions. Various methods are conceivable as a method of engaging the adjusting means with the fitting portion of the mounting body and moving the mounting plate in the left-right direction. For example, in the case where the adjusting means is an adjusting bolt, a threaded portion (fitting portion) in which the adjusting bolt is screwed (engaged) with the mounting body is provided. The part may move forward and backward, and the other end of the mounting plate may move in the left-right direction, for example. Also, the adjusting means is a convex cylinder,
In the case of an adjustment cam having a projection on the side surface of the large-diameter cylinder, the adjustment cam is rotated and the projection is slid along an inclined groove (fitting portion) provided in the mounting body. (Engagement), and along with this slide, the mounting plate on which the small-diameter-side cylinder is fitted may be moved in the left-right direction. Whatever method is used, it is preferable that the method be simple. As described above, the fixing means may be a fixing bolt or the like, but the disposition position is preferably between the position where the support is provided and the position where the adjustment bolt is disposed. This is because a further effect of reducing the load acting on the adjustment bolt can be expected.

The door opening and closing device of the present invention includes a first engaging member fixed to a fixing member, a second engaging member fixed to a door body, and further includes a mounting plate for the first engaging member. The formed first cylindrical body and a second cylindrical body formed on a mounting plate of the second engagement member are connected to each other via an additional member, and the additional member includes a first cylinder. A pivot shaft fixed to the body, a bearing housed in the second cylindrical body, which is fitted to one end of the pivot shaft, and screwed to the bearing to adjust the door in the vertical direction with respect to the fixing member. And a stopper fixed to the second cylindrical body, wherein the head of the adjusting bolt always projects from the second cylindrical body and is fitted to the shaft thereof. A stopper that abuts against the ring so that its head does not protrude beyond a predetermined It is those formed by free. Accordingly, even when the door body is adjusted in the vertical direction with respect to such a fixing member, the head of the adjustment bolt, that is, the portion to be rotated by the driver has a structure protruding from the cylindrical body. In addition, the rotation operation can be performed very easily, and the time and effort required for adjustment resulting from the difficulty in operating the driver by inserting the driver straight into the cylindrical body as in the related art is required.
Can't happen.

Regardless of whether the adjustment bolt is adjusted in the upward or downward direction, the head of the bolt always projects from the second cylindrical body and appears to the outside. The amount is a ring fitted to the shaft of the bolt,
The protrusion amount is determined by the relative position with respect to the stopper fixed to the second cylindrical body. In other words, the amount of protrusion differs depending on where the two come into contact due to the advance and retreat of the bolt. What is necessary is just to select suitably according to environmental conditions.

FIG. 1 shows an example of an embodiment of the present invention.
This will be described with reference to FIGS. The door opening / closing device 1 according to the present embodiment includes a first engagement member 3 fixed to a fixing member 2 and a second engagement member 5 fixed to a door body 4. , 5 are provided, and the first engaging member 3 and the second engaging member 5 are connected to each other via the attaching member, and the engaging members 3, 5 and the attaching member are provided. The cooperation of the members allows the door body 4 to be freely opened and closed. The first engagement members 3 are fixed to, for example, recesses as shown in FIG. 4 provided on the fixed member 2 with screws or the like, and are disposed at two positions with a predetermined interval from the fixed member 2, respectively. On the other hand, the second engaging member 5 is fixed to a predetermined concave portion (not shown) provided in the door body 4 with a screw or the like corresponding to the first engaging member 3 (FIG. 1).

The first engaging member 3 is attached to the mounting body 6.
The mounting body 6 further includes a case body 8 and an adjusting plate 9. The U-shaped portion of the case body 8 is provided in the predetermined recess of the fixing member 2 as described above. Fitted, the flange portion extending from the U-shaped portion is fixed by screws or the like,
The adjustment plate 9 is disposed on the bottom surface of the U-shaped portion and, as described later, is moved in the front-rear direction (the direction of the arrow in FIG. ), And the door member 4 can be adjusted in the front-rear direction with respect to the fixing member 2.

As shown in FIG. 3, one end of the adjusting plate 9 is bent to form a bent portion (support) 9.
a is provided, and the bent portion 9a is provided with a rectangular hole 9b for loosely inserting the mounting plate 7, so that when the mounting plate 7 receives a load from the left direction or the right direction. (The direction of the arrow in the figure is referred to as the left-right direction.)
This load can be evenly dispersed and supported by the bent portion 9a. Further, the adjustment plate 9 is provided with a screw hole (fitting portion) 9c at the other end.
The mounting plate 7 can be moved in the left-right direction by the adjustment bolt (adjustment means) 10 screwed to the position c, and the door member 4 can be adjusted in the left-right direction with respect to the fixing member 2. That is,
When one end of the mounting plate 7 is held by the holding portion 10a provided on the head of the adjustment bolt 10 and the adjustment bolt 10 is moved forward and backward, the held end also moves forward and backward with this movement. The other end of the mounting plate 7, that is, a first cylindrical body 7a described later, moves in the left-right direction with the bent portion 9a as a fulcrum. Thereby, the above adjustment can be performed.

After the adjustment, a fixing means for fixing the mounting plate 7 to the case body 8 is provided between the bent portion 9a of the adjusting plate 9 and the screw hole 9c, that is, between both ends of the adjusting plate 9. The fixing means includes a fixing bolt 1 that is screwed into the screw hole provided in the case body 8 through the mounting plate 7 and the adjusting plate 9.
1. By the way, in the present embodiment,
Two stopper pins 12 are respectively disposed near the bent portion 9a, the heads of the stopper pins 12 protrude from the upper surface of the mounting plate 7, and the shaft portions are mounted parallel to the bent portion 9a. The shaft end penetrates the plate 7 and the end of the adjustment plate 9
Is in contact with the upper surface of the These stopper pins 12
The mounting plate 7 is provided to prevent the mounting plate 7 from coming out of the rectangular hole 9b (FIGS. 1 and 4).

At the other end of the mounting plate 7, the first cylindrical body 7a is formed as described above, and at the upper end inside the cylindrical body 7a, a base shaft of a pivot shaft (attachment member) 14 is provided. As shown in FIG. 2, 14a is fixed by press-fitting. On the other hand, as shown in the figure, the second engaging member 5 is composed of only an L-shaped mounting plate 13, and the mounting plate 13 is provided in the predetermined recess provided in the door 4 as described above. A second cylindrical body 13a is formed at an end of the mounting plate 13 which is directly fixed and connected to the mounting plate 7 via a pivot shaft 14. In the second cylindrical body 13a, a bearing body (attachment member) 15 that fits with the tapered shaft portion 14b of the pivot shaft 14 and abuts on the shaft end portion 14c is housed. And an adjusting bolt (attachment member) 16 for adjusting the vertical direction of the door body 4 with respect to the fixing member 2 (the direction of the arrow in the figure is referred to as the vertical direction).
The adjustment bolt 16 is attached to the head 1
6a always projects from the upper end of the cylindrical body 13a, and a ring (attachment member) 1 fitted to the shaft portion 16b.
Stopper (attached member) 7 fixed inside cylindrical body 13a
18, the head 16 a is more than a predetermined
3a is provided so as not to protrude from the inside to the outside. By the way, in the present embodiment, the ring 17 is fitted to a predetermined position of the shaft portion 16b of the adjusting bolt 16, while the stopper 18 is at a position where the head 16a of the adjusting bolt 16 and the ring 17 are fitted. And the head 16a of the adjustment bolt 16 is fixed to the upper end of the cylindrical body 13a.
However, the structure which always appears outside from the upper end of the cylindrical body 13a is formed.

A method for adjusting the door 4 in the left-right direction with respect to the fixing member 2 by using the above-described apparatus 1 will be described. Adjustment in the left and right direction depending on the installation state of the door body 4,
That is, when the surface of the fixing member 2 and the surface of the door body 4 overlap with each other, it may be necessary to make an adjustment so that the both surfaces overlap well.
Then, when the adjusting bolt 10 is rotated and moved forward and backward, the end of the mounting plate 7 also moves forward and backward with the forward and backward movement, so that the first cylindrical body 7a of the mounting plate 7 is
It moves in the left-right direction with the bent part 9a as a fulcrum. With this movement, the mounting plate 13 moves in the left-right direction via the pivot shaft 14, so that the door body 4 can be adjusted in the left-right direction with respect to the fixing member 2. At this time, even if a load in the left-right direction from the mounting plate 13 is applied to the mounting plate 7, the structure is such that the load is evenly dispersed and supported by the bent portion 9a instead of the adjustment bolt 10. However, unlike the related art, the adjustment bolt 10 is not loosened. In addition, since the adjustment bolt 10 is located on the bent portion 9a side from the position of the fixing bolt 11, that is, on the side opposite to the side supporting the load, the adjustment bolt 10
Can be reduced from receiving a load, which is more effective in preventing the above-mentioned loosening.

Next, a method of adjusting the door body 4 in the vertical direction with respect to the fixing member 2 using the apparatus 1 will be described. Depending on the state of installation of the door body 4, there is a case where it is necessary to adjust the vertical direction. In this case, if the head of the adjustment bolt 16 is rotated by a driver, the adjustment bolt 16 becomes Because the ring 16a and the ring 17 of the shaft portion 16b are in contact with the stopper 18, the bearing body 15 screwed to the adjustment bolt 16 does not advance or retreat, but advances or retreats. However, since the pivoting movement of the bearing body 15 is prevented by the pivot shaft 14, the mounting plate 13 moves vertically with respect to the pivot shaft 14 and the bearing body 15, that is, with respect to the mounting plate 7. Thereby, the vertical adjustment of the door body 4 with respect to the fixing member 2 can be performed. At this time, since the turning operation is performed by the driver, that is, since the head 16a of the adjustment bolt 16 has a structure that always projects from the inside of the cylindrical body 13, the turning operation can be performed very easily. The adjustment hassle that occurs when operating the driver by inserting it straight into the cylinder cannot occur. Also,
The lower end of the second cylindrical body 13a is always loosely fitted in the recess 15a of the bearing body 15, and the mounting plate 13 is
On the other hand, even if it moves in the vertical direction, a large gap is not formed between the plates 7 and 13 and the appearance is not impaired.

Incidentally, in the present apparatus 1, as described above, the front and rear directions of the door body 4 with respect to the fixing member 2 can also be adjusted. That is, as shown in FIG. 4, the plate 9 is provided with a cam engaging hole 9d of a predetermined shape, and the lower shaft 19a of the cam body 19 engaging with the cam engaging hole 9d is While being loosely inserted into the drilled hole of the body 8,
The shaft end is caulked so as not to come out of this hole. Therefore, when the cam body 19 is rotated, the adjustment plate 9 and the mounting plate 7 move integrally in the front-rear direction, so that the door member 4 can be adjusted with respect to the fixed member 2 in the front-rear direction. become. In addition, since the mounting plate 7 is provided with an opening hole (window) 7b for rotating the cam body 19 (FIG. 2), the adjustment in the front-rear direction is different from the adjustment in the left-right direction. Can be done independently.

As described above, the first engagement member 3 and the second engagement member 5 are connected to each other via the attachment member. On the other hand, another set of the first engagement member 3 is provided. The third engaging member 5 is connected to the second engaging member 5 via another attaching member (FIG. 1).
A pair of the first engagement member 3 and the second engagement member 5 above). That is, the mounting plate 13 as the second engaging member 5 has hollow shaft guides 20, 2 at the upper and lower ends of the second cylindrical body 13a.
1 are fitted respectively, the shaft 22 is loosely inserted along the shaft guides 20 and 21, and a stopper 23 is protruded from a substantially central portion of the shaft 22. The stopper 23 is supported by the shaft guide 20, and 23 and axis guide 2
The spring 24 is disposed between the first and second springs. The spring 24 urges the shaft 22 upward in FIG. However, the mounting plate 7 of the first engagement member 3
The shaft 22 extends through the shaft guide 20 and is loosely inserted into a bearing 25 fixed to the first cylindrical body 7a. The shaft guide 21 is provided with a knob 26 also serving as a stopper. In such a case, in order to disengage the first engagement member 3 and the second engagement member 5, that is, the attachment plate 7 and the attachment plate 13, the knob 22 may be operated to move the shaft 22 forward and backward. . That is, the mounting plate 7
In order to release the engagement between the shaft 22 and the mounting plate 13, when the knob 26 is removed, the shaft 22 naturally comes out of the bearing 25 by the urging force of the spring 24. Spring 2
4 may be inserted into the bearing body 25.
