However, in the case of the configuration of the above-mentioned Patent Document 1, the holding operation is troublesome because it is necessary to take out the stopper from the main body side and perform the locking operation on the locking portion on the door side when holding the opened door. It was.
Especially when the cabinet is installed outdoors, the opened door may be blown by the wind. In such a case, the operation to operate the stopper must be performed while supporting the door, It was not easy.

  Therefore, in view of such a problem, the present invention has an object to provide a cabinet door stopper structure having a simple structure in which an open door is held by a holding function that automatically operates in accordance with a door opening operation. Yes.

In order to solve the above-mentioned problems, the invention of claim 1 is a cabinet having a box-shaped cabinet body whose front surface is opened and a door that closes the front surface of the cabinet body by a turning operation. A cabinet door stop structure that holds a door in a closed state by spanning a stopper member between the door and a door that is disposed at a lower portion of the opening of the cabinet body and rotatably supports the base of the stopper member. A metal fitting and a guide metal fitting that is disposed at a lower portion of the door and supports a tip end of the stopper member, and the receiving metal fitting is arranged in the vicinity of a side portion that is hinged to the door, and a base portion of the stopper member. The guide fitting allows the door to be opened and closed with the end of the stopper member inserted. A long hole formed in the lateral direction along the door back to the door and having a regulating means for inhibiting the return movement in said elongated hole of the stopper member after opening up to a predetermined angle.
According to this configuration, since the door can be opened while the stopper member is guided by the guide fitting, the stopper member is moved from the closed state to the locked state until the door return is restricted and the locked state is reached. There is no need to operate. Therefore, even if it is installed outdoors and blown by the wind, the opened door can be easily held and the opening operation is easy.

According to a second aspect of the present invention, in the configuration according to the first aspect, the regulating means is formed along the elongated hole so as to continue to place the intermediate portion of the stopper member while the door is opened to the predetermined angle. When the stopper member is opened at the predetermined angle, the stopper member moves past the end of the band-like support piece, and the loaded state is released and dropped, so that the end of the band-like support piece Therefore, the return movement in the long hole is prohibited.
According to this configuration, since the stopper member is simply dropped into the end of the belt-like support piece, the operation for closing the door is performed by lifting the stopper member and placing the intermediate portion on the belt-like support piece. Is easy.

According to a third aspect of the present invention, in the configuration according to the second aspect, the stopper is a stopper support surface formed so as to be inclined in the left-right direction so that the door is inclined upward from one to which the door is hinged. The support hole is formed in the stopper support surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing an example of a cabinet provided with a door stop structure according to the present invention. A cabinet 1 is composed of a cabinet body 1a and a door 2, and shows a state in which the door 2 is opened.
The cabinet body 1a is provided with an opening 10 that is largely open on the front surface, and the other surface is closed. The door 2 is provided so as to close the opening 10, and a stopper member 3 for holding the opened door 2 is stretched between the two.

  The left side of the door 2 is hinged to the cabinet body 1a via a hinge 11, and opens / closes the opening 10 of the cabinet body 1a by a turning operation. The stopper member 3 is configured to hold the door 2 at a predetermined angle by locking the end to a receiving metal fitting 4 provided on the cabinet body 1a and a guide metal fitting 5 provided on the door 2 side. The door stopper structure is constituted by the receiving metal fitting 4 and the guide metal fitting 5.

FIG. 2 shows an enlarged view of the A part, and enlarges the door stopper structure. Moreover, FIGS. 3-5 has shown the perspective view of each member of a door stop structure part. The door stopper structure will be described with reference to FIGS.
As shown in FIG. 3, the stopper member 3 has a U-shape in which both ends of the metal bar are bent, and is formed at the lower body locking portion 3 a formed at one end serving as a base and the other end serving as a tip. A downward-facing door engaging portion 3b and a central intermediate long side portion 3c are provided. The main body locking portion 3a is supported by a receiving metal fitting 4 described later, and the door engaging portion 3b is engaged with the guide metal fitting 5 and slides.

As shown in FIG. 4, the metal fitting 4 is formed by bending a belt-shaped steel plate into a substantially U-shape, provided with support holes 13 for inserting and supporting the stopper member 3 on the upper surface 4a, and left and right sides bent downward. The bent pieces 4b and 4c form a fixing portion to the cabinet body 1a. The upper surface 4a is inclined and the support hole 13 is drilled at a portion close to the one bent piece 4b formed low.
The receiving metal fitting 4 formed in this way is attached to the left end of the lower portion of the opening 10 so as to incline upward toward the right which is the door 2 open end side of the cabinet opening 10.

As shown in FIG. 5, the guide metal fitting 5 is formed by bending the left and right long sides of a rectangular plate body into a U-shape, and the door engaging portion 3b of the stopper member 3 is inserted into the central flat portion formed in a concave shape. Thus, a long hole 14 is formed for guiding. One of the strips that is bent and formed upright has an upper side of a uniform height and forms a strip-shaped support strip 5 a that engages with the stopper member 3. Similarly, the other band piece formed upright is an attachment piece 5 b fixed to the back surface of the door 2. A through hole 16 into which the door engaging portion 3b can be inserted is formed at the end of the central flat portion that continues to the long hole 14.
The main body locking portion 3 a of the stopper member 3 is inserted into the support hole 13 of the receiving metal fitting 4 and pivotally attached, while the door engaging portion 3 b is slidably inserted into the elongated hole 14 of the guide metal fitting 5. The

Here, the positional relationship among the receiving metal fitting 4, the guide metal fitting 5, and the long hole 14 will be specifically described. 6 and 7 show a state in which the door 2 of the cabinet 1 in FIG. 1 is closed, and both show the door 2 with the structural members of the door stopper structure omitted. FIG. 8 shows an enlarged view of the B part.
As shown in FIG. 8, the right end of the receiving metal fitting 4 is attached so as to be disposed at a position higher than the belt-like support piece 5 a of the guide metal fitting 5. In FIG. 8, ΔH indicates a difference in height between the uppermost part of the receiving metal 4 and the upper side of the belt-like support piece 5a, and indicates that the highest position of the metal receiving metal 4 is higher than the belt-like support piece 5a. In addition, the site | part in which the support hole 13 was formed is formed in the position lower than the strip | belt-shaped support piece 5a.

  On the other hand, the right end of the long hole 14 that is the open end side of the door 2 is formed with a length sufficient to allow the stopper member 3 to slide even when the door 2 is closed. It is formed with a specific distance from the end of the support piece 5a. Specifically, when the door 2 is opened and the stopper member 3 is detached from the end of the belt-like support piece 5a and falls (this is opened to a predetermined angle), the door engaging portion 3b of the dropped stopper member 3 is placed. Is located at the left end portion of the long hole 14, and the back and forth movement is prohibited on the long hole 14.

  The operation of the door stopper structure configured as described above is as follows. By disposing the receiving metal fitting 4 and the guide metal fitting 5 in this way, the stopper member 3 is in a state parallel to the opening surface of the opening 10, that is, in the left-right direction in the closed state. Stop part 3a will be in the state where it climbed up the inclined surface and moved to the highest position of receiving metal upper surface 3a. As a result, the intermediate long side portion 3c of the stopper member 3 moves to a position higher than the belt-like support piece 5a, and even if the door 2 starts to be opened and becomes crossed, they do not contact each other. However, the door engaging portion 3b at the tip maintains the state inserted in the long hole 14, and moves to the farthest portion (the right side shown in FIGS. 6 and 7) of the long hole 14 in the closed state.

  When the door 2 is opened from this closed state, the tip of the stopper member 3 slides through the long hole 14 and starts to move to the left, and the intermediate long side portion 3c starts to move in a direction crossing the belt-like support piece 5a. . Then, as the opening angle increases, the stopper member 3 rotates to move in a lower direction of the inclined upper surface 4a, and the main body locking portion 3a gradually moves downward. As a result, the middle long side portion 3c of the stopper member 3 comes into contact with the belt-like support piece 5a and slides on the belt-like support piece 5a from the middle of the opening operation. The door engaging portion 3b of the stopper member 3 slides in the long hole 14 during this period.

This state is continued until the door 2 is opened at a certain angle, and when the certain angle is reached, as shown in FIG. 1, the engaging portion of the intermediate long side portion 3c with the belt-like support piece 5a is the belt-like support piece 5a. It reaches the end (the end of the guide metal fitting) and eventually falls from the mounted state and engages with the left side 15 (shown in FIG. 5) of the belt-like support piece 5a.
At this time, the door engaging portion 3b of the stopper member 3 continues to be engaged with the long hole 14, but has moved to the end of the long hole 14 on the door butterfly side, so that the belt-like support piece 5a When the side portion 15 and the stopper member 3 are engaged, the movement on the long hole 14 is restricted, and the door 2 maintains the angle. Thus, the door 2 opened to a certain angle maintains its state. Furthermore, at this time, the insertion destination of the door engaging portion 3 b can be replaced from the long hole 14 to the through hole 16.

  When closing the door from the holding state in which the door 2 is opened, the stopper member 3 may be lifted to release the engagement with the side portion 15 of the belt-like support piece 5a, and if the door 2 is closed in the released state, the stopper member 3 is closed. Slides in the long hole 14 while being placed on the belt-like support piece 5a, and returns to the initial state shown in FIG.

As described above, since the door can be opened while the stopper member 3 is guided by the guide metal fitting 5, the door 2 is opened from the closed state, and the return of the door 2 is restricted to reach a locked state. Until then, it is not necessary to operate the stopper member 3. Therefore, even if it is installed outdoors and blown by the wind, the opened door 2 can be easily held and the opening operation is easy.
The operation of closing the door 2 may be performed by lifting the stopper member 3 and placing the intermediate long side portion 3c on the belt-like support piece 5a, and the operation of closing the door 2 is simple.
Further, since the support hole 13 for inserting the base portion of the stopper member 3 has an upward slope from either one of the left and right sides where the door 2 is hinged to the other, the stopper member 3 is in a state where the door 2 is closed. The base portion of the stopper member 3 moves to a high position, and in the closed state, the stopper member 3 moves to a height that does not engage with the belt-like support piece 5a. Therefore, regardless of the presence or absence of the belt-like support piece 5a, the stopper member 3 can be smoothly moved in the long hole 14 when the door 2 starts to be opened.
In addition, if the tip of the stopper member 3 is replaced from the long hole 14 to the through hole 16, sliding of the stopper member 3 can be completely prohibited, so that a situation in which the lock is released during the operation and the door 2 is opened and closed is prevented. it can.

In the above embodiment, each of the long holes 14 and the through holes 16 is one, but a plurality of them can be provided. For example, if a plurality of the long holes 14 are provided adjacent to each other in parallel, the angle at which the opened door is held can be changed, and an optimum angle can be set according to the installation environment. Similarly, by providing a plurality of through holes 16, it can be fixed at an optimum angle according to the installation environment.
Moreover, although the door 2 is provided in the front surface of the cabinet 1, the surface in which the door was provided is made into the front surface, and when the door is provided in the side surface and can be opened, this side becomes the front surface. Furthermore, when the cabinet is provided with doors 2 on a plurality of surfaces, the door stopper structure of the present invention can be applied to each door 2.
