Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door structure used for a case such as furniture, in which a pair of left and right rotating doors are opened and closed in a double-door manner.

[0002]

2. Description of the Related Art In a door structure that opens and closes like a double door, there is a gap between the left and right pivoting doors, and the interior of the case can be seen and dust and harmful insects can enter. In order to prevent this from happening, an assembling member that is long in the vertical direction may be provided along the inner surface of the free end side of one of the pivot doors.

Conventionally, in this kind of door structure, a structure has been developed in which the rotating door on the side provided with the assembling member can be opened and closed even when the other rotating door is closed. For example, as shown in FIGS. 6 and 7, a summing member 51 integrally formed with a hinge 52 is rotatably provided on one rotating door 53 so that a pivot shaft 54 of the summing member 51 faces in the vertical direction. Is that. The summing member 51 closes the summing portion gap S on the inner surface side of the rotating doors 53 and 55 (shown by a solid line) and the avoiding posture in which the summing member 51 is tilted backward so as not to contact the other rotating door 55 ( (Shown by the chain double-dashed line)
It is biased in the avoidance posture direction by the coil spring 56.
Further, in the process of closing the rotary door 53 provided with the summing member 51, the case is a receiving surface portion that abuts on the inner surface side of the summing member 51 to guide the summing member 51 to the above-mentioned closed posture. 57 is provided (see Japanese Utility Model Publication No. 62-27672, U.S. Pat. No. 3653155, etc.).

[0004]

The receiving surface portion 57 is
It was formed on the front part of the bar or block that was fixed in place on the lower surface of the top plate or the upper surface of the bottom plate of the case.To secure these bar and block materials to the case, High accuracy was required for positioning the front opening in the left-right direction and the front-back direction. This is because, in the process of closing the rotary door 53 on the side provided with the assembling member 51, the inner surface near the tip of the assembling member 51 is the receiving surface portion 5.
7 so as to smoothly follow (prevent the tip from hitting), and at the time when the rotary door 53 is completely closed, the receiving surface portion 57 has the receiving surface portion 57.
This is because it is necessary to just make the front surface of the assembling member 51 and the inner surfaces of the two rotating doors 53 and 55 contact each other in the state where 1 is backed up. In addition to the fixing of the rod member and the block member, the position at which the hinge 52 is attached also causes an inconvenience in opening and closing the rotary door 53. Therefore, there is a drawback that adjustment and assembly of the entire door structure is difficult and troublesome.

The present invention has been made in view of the above circumstances, and eliminates all the difficulties and troubles due to the positioning of the receiving surface portion, so that the entire door structure can be easily assembled. It is an object of the present invention to provide a door structure for a case and a hinge tool used for the door structure.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, in the door structure according to the present invention, a pair of left and right rotating doors that can open and close the case front opening in a double-opening manner and a summing portion gap formed between the free ends when both rotating doors are closed. Of these, a summing member that closes the inner portion of the case front opening in the height direction, and the summing member with the summing member along the inner surface of the free end of either one of the rotating doors. At least one hinge tool, which comprises a hinge tool for rotatably holding the armature through a pivotal shaft facing up and down, and a spring for biasing the assembling member in a rearward tilted posture with respect to the pivot door. Is arranged near the upper end or the lower end of the assembling member, and the hinge tool in this arrangement has a front opening of the case that projects above the upper end holding portion of the summing member or below the lower end holding portion. A guide piece that can be brought into contact with the peripheral edge is provided. That.

Further, in the hinge tool according to the present invention, the mounting base, the butterfly moving piece movably held by the mounting base via the pivotal shaft, and the butterfly moving piece being fixed around the pivotal shaft. And a spring for urging and pressing so as to hold it in an inclined posture, and the butterfly piece is formed with a socket portion into which one end portion of the assembling member is fitted along the longitudinal direction of the pivot shaft. The guide piece is provided so as to project in a direction opposite to the extending direction of the assembling member fitted in the socket portion.

[0008]

According to the present invention, when the pivoting door on the side provided with the summing member is closed, a hinge tool arranged so as to hold near the upper end or the lower end of the summing member is moved. The guide piece provided on the piece comes into contact with the peripheral portion of the front opening such as the front surface of the top plate portion or the front surface of the bottom plate portion of the case.
Therefore, as a result, the summing member is rotated in the direction (forward) in which the tilted posture is returned. Therefore, it is not necessary to purposely provide the case with a receiving surface made of a rod material, a block material, or the like.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a case such as a closet, which is provided with a pair of left and right rotating doors 2 and 3 so as to close the front opening. Each of the swing doors 2 and 3 can be opened and closed like a double door by a hinge 4 attached to the inner surface of the side plate portion 1c of the case 1 such that the swing axis is oriented in the vertical direction. Reference numeral 5 is a closing door holder for the revolving doors 2 and 3, which is constituted by a combination of a magnet and a suction plate, and 6 is a handle. As shown in FIG. 2, when both the swing doors 2 and 3 are in the closed state, a summing portion gap S having a predetermined width is formed between them. A summing member 10 that closes the summing portion gap S is attached to one of the rotating doors 2 along the inner surface of the free end side. As shown in FIG. 3, the summing member 10 has a vertical length substantially corresponding to the inner dimension in the height direction at the front opening of the case, and is arranged near the upper end and the lower end. It is held on the revolving door 2 via two upper and lower hinge tools 11 (see FIGS. 1 and 2).

As shown in FIGS. 4 and 5, the hinge tool 1 is used.
1, the mounting base 13 and the butterfly motion piece 14 are assembled in a butterfly motionable manner via a pivot shaft 12 having an axis centered vertically, and a butterfly spring motion piece 14 is fitted by a coil spring 15 fitted to the pivot shaft 12. Is urged to maintain a predetermined inclined posture around the pivot shaft 12. Therefore, the hinge tool 11 keeps the summing member 10 in a rearwardly inclined posture with respect to the rotary door 2, and twists the coil spring 15 from the rearwardly inclined posture to the posture parallel to the rotary door 2. It can rotate while resisting the biasing force.

A socket portion 1 into which one end portion of the assembling member 10 can be fitted into the butterfly motion piece 14 of the hinge tool 11.
6 is formed. This socket part 16 is a butterfly motion piece 1.
In order to allow the front surface of the summing member 10 and the inner surfaces of the swiveling doors 2 and 3 to come into contact with each other in a pair even when the swiveling movement of the swiveling door 4 toward the inner surface of the swiveling door 2, the summing member It is formed in a side-opening shape so as to expose the front surface of 10. Also,
The butterfly motion piece 14 is provided with a guide piece 18 protruding in a direction opposite to the direction in which the summing member 10 extends. The guide piece 18 can come into contact with the front opening peripheral edge portion such as the front surface of the top plate portion 1a or the front surface of the bottom plate portion 1b in the case 1 in the process of closing the rotary door 2. In addition, the hinge tool 11 for holding the vicinity of the upper end of the assembling member 10
Needless to say, with the hinge tool (details are not shown) that holds the vicinity of the lower end, the shape (opening direction) of the socket portion 16 and the protruding direction of the guide piece 18 are inverted upside down.

In the door structure of the present invention thus constructed, the rotary door 2 on the side provided with the assembling member 10 is in the open state and the other rotary door 3 as shown by the two-dot chain line in FIG. When the former (revolving door 2) is closed while the door is closed, the guide pieces 18 of the upper and lower hinge tools 11 contact the front surface of the top plate portion 1a and the front surface of the bottom plate portion 1b of the case 1 respectively. Then, the butterfly moving piece 14 is gradually moved in the direction of returning the rearward tilted posture of the summing member 10 according to the degree of closing of the rotating door 2. Along with this, the summing member 10 causes the other rotating door 3 to move.
It is inserted into the inner side of. When the revolving door 2 is completely closed, the front portion of the assembling member 10 has both revolving doors 2, 2.
The contacting portion 3 comes into contact with the inner surface 3 and closes the assembling portion gap S.

On the other hand, when both the swinging doors 2 and 3 are in the closed state, when the swinging door 2 on the side provided with the assembling member 10 is opened, the operation substantially reverse to the above is performed. by the way,
When the vertical length of the assembling member 10 becomes long, a hinge tool (not shown) is provided in the middle portion thereof so that neither the guide piece 18 nor the socket portion 16 is provided (the coil spring 15 is unnecessary in some cases). You can do it like this. On the contrary, when the summing member 10 has a short vertical length, the guide piece 18 is provided only near either the upper end or the lower end thereof.
Is provided with a hinge tool 11 and the like, and a guide piece 18 is provided on the other part.
It is also possible to hold the assembling member 10 by providing a hinge tool that does not include the like.

[0014]

According to the present invention, which has the above-mentioned structure, when the pivoting door on the side provided with the assembling member is closed, the hinge tool is attached to the peripheral portion of the front opening of the case. Since the guide piece provided on the butterfly moving piece abuts and the summing member is rotated by this, there is no need to purposely provide the case with a receiving surface portion made of a rod material, a block material or the like. Therefore, of course, all the difficulty and troublesomeness at the time of positioning due to the provision of the receiving surface portion are eliminated, and the difficulty of positioning adjustment of the hinge tool is also eliminated, and the number of parts is reduced. Assembling the door structure as a whole becomes easy. Further, since the hinge having the guide piece is necessarily positioned near the upper end or the lower end of the summing member, the summing member is not bent or twisted or broken, and Since swinging does not occur when the assembling member rotates,
It is possible to smoothly rotate the assembling member and surely close the assembling portion gap.
