Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a door mounting mechanism for mounting a door on a housing or the like in a freely openable and closable manner.

[Conventional technology]

2. Description of the Related Art Conventionally, various casings for storing and storing various stored items such as industrial products, documents, daily necessities, and food have been developed and used.

By the way, in this case, for example, as shown in FIG.
In order to close the opening portion 101 of the housing 100, many housings 100 in which a door 102 is rotatably attached have been developed. A hinge 103 or the like is usually used as a means for attaching the door 102 to the housing 100.

[Problems to be solved]

By the way, in the case of using the hinge such as the hinge, not only is the installation work of the hinge and the door troublesome, but it is difficult to assemble the door to the side plate on the housing side, and the door often tilts obliquely. It may be installed in a state.

Further, when such hinges are used, it is difficult to mount the doors at the same level height with respect to the respective housings, for example, when the same housings with the doors are arranged in a line.

Therefore, in view of the above-mentioned conventional drawbacks, the present invention compares doors that are relatively easy to attach, easily improve the assembling accuracy of the door, and are relatively heavy in weight. It is an object of the present invention to provide a door mounting mechanism capable of supporting a relatively high strength.

[Means for Solving the Problems]

That is, the door mounting mechanism of this invention is such that the upper and lower sides of the door are bent 90 degrees inward at the upper and lower edges of the side plates attached to the frame of the housing facing them, respectively. A door mounting mechanism for rotatably supporting the formed top surface side and floor surface side, wherein a support portion having a support metal fitting protruding a pin-shaped projection is provided on the side plate side top surface and floor surface. The door-side upper and lower surfaces are provided with receiving portions having engaging holes into which the protrusions are inserted and engaged.

[Action]

In the door mounting mechanism of the present invention, for example, a metal member having a pin-shaped protrusion is mounted on the side plate side of the housing to form a support portion, and an engaging hole with which the protrusion is engaged is opened on the upper and lower surfaces of the door side. To form a receiving part, and insert the protrusion into the receiving part to attach the door, which is easier to install than the conventional hinges and the like, and improves the assembly accuracy. It is easy to do.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show a door mounting mechanism according to the present invention, which has a structure in which a support portion is provided on the housing 1 side and a receiving portion is provided on the door 2 side. There is.

The housing 1 is assembled by a frame formed by columns 3 and beams 4 forming the skeleton thereof, and side plates 5, a top plate 6, a floor plate 7, a back plate 8 and the like attached to this frame. Is solidly formed to hold a heavy switchboard. The supporting portion of the housing 1 is formed by bending the upper edge and the lower edge of the side plate 5 which are less vertically distorted and displaced 90 ° inward because they are sandwiched between the columns 3. The support fittings 10 are provided on the tip side of the top surface 5a and the tip side of the floor surface 5b, and the support fittings 10 having the pin-shaped protrusions 9 projecting therefrom are screwed onto the respective top surfaces.

The door 2 is formed in a box-shaped rectangular shape, and projections 9 are inserted on the upper surface 2a side and the lower surface side 2b of the folding surface provided around the door.
A receiving portion formed of engaging holes 11 that engage with each other is provided.

Therefore, according to the door mounting mechanism of this embodiment, it is easy to increase the mounting accuracy of the door 2 with respect to the side plate 5 and to mount the door 2 in a parallel state. Therefore, when the door is mounted using a conventional hinge. That is, it is possible to prevent the door 2 from being obliquely displaced from the side plate 5 as shown by the dotted line in FIG.

Further, according to the door mounting mechanism of this embodiment, when a plurality of housings 1 to which the doors 2 are mounted are arranged side by side, for example, another door 2
The level matching with the door 2 of another housing 1 can be achieved by arranging an appropriate spacer or the like at the mounting portion of the protrusion 9 on the support metal fitting 10 on the floor surface 5b side by a thickness corresponding to the height displacement. Easy to do.

〔effect〕

As described above, according to the door mounting mechanism of the present invention, it is supported from the up and down direction by the support fittings attached to the side plates that are sandwiched between the pillars on the housing side and the vertical displacement is suppressed as much as possible. Since the door is relatively easy to install and there is little risk of vertical displacement even after long-term use, it is possible to prevent the external appearance from being spoiled over a long period of time, which leads to high quality. A housing can be provided. Furthermore,
When assembling the doors, the parallelism of the doors can be accurately obtained with respect to the side plates of the housings, etc., and the height levels of the doors of each housing arranged in the lateral direction can be easily adjusted. And so on.

Further, according to this invention, the floor or top surface on the side plate side is attached to the vast floor board or top board that occupies the floor or ceiling of a wide area, and the support metal fittings are attached to this, so the support strength of the door is greatly increased. Even if a door having a heavy weight is attached, it is possible to prevent the door from tilting and shifting.
