Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the above conventional mounting structure, the contact portion of the panel is supported by a linear and small-area contact portion. And, at the time of the mounting work, since the inclination of the panel is changed in a state where a load is concentrated on the small contact portion, the members are rubbed against each other at the contact portion and are damaged, and there is a problem that the rust-preventive coating or the like is peeled off. Also, even when the panel is attached, since the load is always applied to the contact portion, the coating may be damaged.

[0005] Therefore, an object of the present invention is to provide a door mounting structure in which the load applied to the contact portion between the box body and the door is sufficiently dispersed when attaching the door to close the opening of the box body having an opening in a cabinet or the like.

Means for Solving the Problems

[0006] To achieve the above objective, the invention described in claim 1 is a door mounting structure for attaching a door to a box body having a front opening, wherein the box body has a support surface at the lower edge of the front opening that supports the lower part of the door, and the door is provided with a contact portion at its lower end that extends toward the rear side, the contact portion having a contact surface parallel to the support surface, and the door is attached to the box body by bringing the contact surface into contact with the support surface from above, and fitting the door into the front opening while the contact surface and the support surface are in contact. Furthermore, the invention described in claim 2 is characterized in that, in the invention described in claim 1, the contact portion has an inclined surface extending downward or upward from the rear end of the contact surface. Furthermore, the invention described in claim 3 is characterized in that, in the invention described in claim 1, the dimension of the contact surface in the front-rear direction is longer than the dimension of the support surface in the front-rear direction. Furthermore, the invention described in claim 4 is characterized in that, in the invention described in any one of claims 1 to 3, left and right guide portions for adjusting the position in the left-right direction when attaching the door to the front opening are provided so as to protrude from the left and right ends of the door to the rear surface. [Effects of the Invention]

[0007] According to the present invention, the door is attached to the cabinet body while maintaining a state in which the contact surface provided on the door is in contact with the support surface, and the door is in a state in which the contact surface and the support surface are in contact when the door is attached.

[0008] Therefore, the contact portion makes it easy to adjust the vertical position of the door during installation, and because the contact surface of the mounting bracket makes surface contact with the support surface during and after installation of the door, the load is distributed, making it less likely for the paint on both contact points to peel off and thus maintaining the rust-preventive effect.

[Modes for carrying out the invention]

[0010] Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. Figure 1 is a perspective view showing a cabinet 1 having a door mounting structure according to the present invention. Figure 2 is a perspective view showing the cabinet body 2 (an example of a "box") with the door 3 removed. Figure 3 is a perspective view of the door 3 alone, viewed from the rear. Figure 4 is a vertical cross-sectional view of the lower part of the cabinet showing the state in which the support fitting 4 is in contact with the support surface 2a. Figure 5 is a perspective view showing the support fitting 4. In the cabinet 1, the surface to which the door 3 is attached is the front, and the surface opposite the front is the rear. In this embodiment, an example is shown in which the cabinet body 2 has an opening at the front and the door 3 is attached, but the configuration is not limited to the front of the cabinet body 2; it is acceptable as long as it is provided on at least one of the front, side, and rear surfaces.

[0011] As shown in Figures 1 to 3, the cabinet 1 having a door mounting structure according to the present invention consists of a cabinet body 2 having a front opening M on one side of the front and a storage space for housing equipment on the other side which is closed, and a door 3 that closes the front opening M of the cabinet body 2. As shown in Figure 4, the cabinet body 2 has a support surface 2a at the lower edge of the frame on which a drainage structure is formed for the front opening M. The support surface 2a is for adjusting the position of the door 3 by bringing it into contact with the contact surface 11 of a fastening fitting 4, which will be described later. The rear surface of the door 3 is provided with a fastening fitting 4 located at the bottom and a locking rod 5 assembled in the vertical direction. The front surface of the door 3 is provided with a handle 6 for moving the locking rod 5 up and down. The door 3 is attached to the cabinet body 2 by adjusting its position with the fastening fitting 4, and then operating the handle 6 to move the locking rod 5 up and down and lock it to the cabinet body 2.

[0012] As shown in Figure 5, the support bracket 4 is a fitting used to adjust the position of the door 3 when attaching the door 3 to the cabinet body 2, and has a plate-shaped fitting body portion 7 that is attached horizontally to the lower rear side of the door 3, a contact portion 8 that is bent from the lower center of the fitting body portion 7 toward the rear side, and left and right guide portions 9 that are bent from both the left and right ends of the fitting body portion 7 toward the rear side. As shown in Figures 3 and 4, the support bracket 4 may be fastened and fixed to the door 3 with bolts, nuts, etc., or it may be fixed by welding or other methods.

[0013] The contact portion 8 has a width in the left-right direction that is at least half the left-right width of the door 3, and consists of a contact surface 11 formed by bending the metal fitting body 7 from the lower center toward the rear side parallel to the support surface 2a, and an inclined surface 12 that extends downward from the rear end of the contact surface 11. The dimensions of the contact surface 11 in the front-rear direction are longer than the dimensions of the support surface 2a in the front-rear direction. The left and right guide portions 9 are formed by bending the metal fitting body 7, which is the left and right end of the door 3, toward the rear side from both the left and right ends, and their tips are bent inward.

[0014] The following describes the procedure for attaching the door 3 to the cabinet body 2 in the cabinet 1. First, the left and right guide portions 9 of the support bracket 4 are used to adjust the left-right position of the door 3, and the inclined surface 12 of the contact portion 8 is brought into contact with the support surface 2a from above, thereby supporting the door 3 to the cabinet body 2. At this time, the upper end of the door 3 is separated from the upper end of the front opening M, and the door 3 is supported in a position that is inclined forward and downward relative to the front opening M, and the support surface 2a and the inclined surface 12 are in surface contact. Surface contact means that two surfaces (in this embodiment, the support surface 2a and the inclined surface 12, or the support surface 2a and the contact surface 11, which will be described later) are in contact in a substantially parallel state. Then, while maintaining surface contact between the support surface 2a and the inclined surface 12, the door 3 is made vertical using the inclined surface 12 as a pivot point, and the door 3 is moved to slide toward the rear so that the contact surface 11 makes surface contact with the support surface 2a after the inclined surface 12, and the door 3 is fitted into the front opening M of the cabinet body 2. Then, by operating the handle 6 and locking the locking rod 5 to the cabinet body 2, the door 3 is attached to the cabinet body 2.

[0015] According to the above configuration, the contact portion 8 makes it easy to adjust the vertical position of the door 3 during installation. Furthermore, after the door 3 is installed, the contact surface 11 of the mounting bracket 4 makes surface contact with the support surface 2a, distributing the load. This prevents the paint on both contact points from peeling off, thus maintaining the rust-preventive effect. Additionally, during installation, the inclined surface 12 and the support surface 2a are kept in surface contact while the door 3 is fitted into the cabinet body 2. Therefore, the inclined surface 12 acts as a guide when bringing the contact surface 11 into contact with the support surface 2a. The surface contact between the inclined surface 12 and the support surface 2a distributes the load, preventing the paint on both contact points from peeling off, and making it easier to lift the door 3 when installing it. Furthermore, since the dimension of the contact surface 11 in the front-to-back direction is longer than the dimension of the support surface 2a in the front-to-back direction, the contact portion 8 can easily reach the support surface 2a even when the door 3 is far from the front opening M of the cabinet body 2. In addition, after the door 3 is installed, the support surface 2a and the contact portion 8 make sufficient contact in the front-to-back direction, so the load is sufficiently distributed.

[0016] Note that the door mounting structure according to the present invention is not limited to the aspects of the above embodiments, and not only the overall configuration of the door mounting structure but also the configuration of the cabinet having the door mounting structure and the like can be appropriately changed as necessary.

[0017] For example, in the contact portion 8 of the pad fitting 4, the inclined surface 12 is inclined downward, but as shown in the perspective view showing a modified example of the pad fitting 4 in FIG. 6, the inclined surface 12 may be inclined upward. According to this configuration, compared with the inclined surface 12 inclined downward, when the door 3 is attached to the cabinet main body 2, the amount of lifting the door 3 is reduced, so that it becomes easier to attach the door 3 to the cabinet main body 2 at a high position.

[0018] Also, in the present embodiment, the support surface 2a is provided at the lower edge of the frame where the drainage structure of the front opening M of the cabinet main body 2 is formed, and the pad fitting 4 is formed on the door 3 in accordance with the support surface 2a. However, the position and configuration of the pad fitting 4 can be appropriately determined according to the structure of the cabinet main body 2. For example, in the cabinet main body 2, as shown in the longitudinal sectional view of the lower part of the cabinet showing the first modified example of the cabinet main body 2 in the support surface 2a portion of FIG. 7, the support surface 2a of the front opening M has a combined structure, or as shown in the longitudinal sectional view of the lower part of the cabinet showing the second modified example of the cabinet main body 2 in the support surface 2a portion of FIG. 8, a configuration in which the support surface 2a is provided at the lower edge where the frame structure of the front opening M is formed is conceivable, and the pad fitting 4 may be formed on the door 3 in accordance with these configurations.

[0019] Also, the left and right guide portions 9 are formed by bending from both ends of the pad fitting 4, but as long as the position adjustment of the door 3 in the left - right direction is possible, they may be formed as a separate body from the pad fitting 4. For example, a configuration in which the left and right guide portions 9 are formed by bending from the upper both ends on the rear surface side of the door 3 may be provided.
