Abstract

<P>PROBLEM TO BE SOLVED: To provide a shape of the end of a packing having a simple structure for ease of work and being capable of enhancing dustproof and waterproof performance. <P>SOLUTION: The shape of the end of a packing 7 is formed so that a gap between a box body and a door body is filled and no gap is formed at the seam of the packing by cutting the length of the packing 7 to accommodate the size of a door body 5 and by cutting the adjacent ends of the packing 7 in a shape that allows the ends to properly meet each other when being confronted with each other except for vertical cutting. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a cabinet for housing various electrical / communication devices including a box body having an opening on at least a front surface and a door body that covers the opening.

A cabinet for storing electrical equipment, communication equipment, etc. is composed of a box body having an opening on the front surface, a frame attached to the periphery of the opening of the box body, and a door body that covers the front opening. .
If there is a gap between the box body and the door body, dust and rainwater may enter and affect internal devices. Therefore, a method of attaching a flat packing 31 having a uniform thickness to the door body has been adopted. The door was closed to the box body so that there was no gap.
The packing 31 was cut into an arbitrary length and used by joining one end and the other end. FIG. 4 shows a state where the doors are joined at the corners, and FIG. 5 shows a state where the doors are joined at the straight portions. The cut surface is straight, and the seam 31a is vertical when affixed to the door.

JP-A-8-288669

  However, as described above, when packing is attached to the door body with a straight cut surface and a seam vertical, rainwater and dust are sucked up by capillarity and the seam length is short. There was a drawback that it was easy to penetrate.

  Therefore, the present invention has an object to provide a packing end shape which can be easily operated with a simple structure and can improve dustproof and waterproof performance. The length is cut together, and the end portions of adjacent packings are cut into shapes that match each other, except for cutting vertically.

  Moreover, it cut | disconnects so that a packing edge part may become a slope.

  Moreover, it cut | disconnects so that a packing edge part may form a step shape.

  The shape of the packing end portion according to the present invention is a shape that matches when the packing is cut to a length corresponding to the size of the door body, and the end portions of adjacent packings are cut vertically except for being cut vertically. Therefore, the seam of the packing can be surely connected and provided without a gap, and the dustproof and waterproof performance can be improved.

  Further, since the packing is cut so that the end portion of the packing is inclined, the packing seam can be surely connected and provided without a gap. Further, since the distance is longer than the state in which the seam is provided vertically, even if dust or rainwater is sucked into the seam, it does not ooze out into the box body.

  Further, since the packing ends are cut so as to form a step shape, the seams of the packing can be reliably connected and provided with no gap. Further, since the distance is longer than the state in which the seam is provided vertically, even if dust or rainwater is sucked into the seam, it does not ooze out into the box body.

It is explanatory drawing which shows the packing sticking state of a cabinet. It is explanatory drawing which shows the implementation method which cut | disconnected the cross section of packing to the slope. It is explanatory drawing which shows the implementation method which cut | disconnected the cross section of packing into the step shape. It is explanatory drawing which shows the joint line of the conventional packing. It is explanatory drawing which shows the joint line of the conventional packing.

  An embodiment showing the shape of the end portion of the packing according to the present invention will be described with reference to the accompanying drawings of FIGS.

    The cabinet 1 is composed of a box body 3 having an opening 2 on the front surface for housing equipment, a frame body 4 attached to the periphery of the opening 2, and a door body 5 that covers the front opening 2 of the frame body 4. The The peripheral edge portion of the front opening 2 of the frame 4 is formed by bending a draining portion 6 to prevent rain water or dust from entering the opening 2 to some extent. However, if the cabinet 1 is installed in a factory where dust is likely to be generated, where it is exposed to outdoor rainwater, or in poor conditions, rainwater and dust can be removed with the drainage structure alone. Intrusion could not be prevented.

  Therefore, a method is adopted in which the packing 7 is attached to a position of the door body 5 facing the opening 2 when the door body 5 is closed to the box body 3. The packing 7 is cut and used in an arbitrary length according to the size of the door body 5. One piece may be affixed to one side of the door body 5, or one round may be covered with one packing 7. The end portions of the adjacent packings 7 are cut in a shape that matches when they are abutted with each other, and a shape that is not cut vertically.

  Since the seam 7a matches, no gap is formed between the packing 7 and the packing 7, and the shape is improved to improve the dustproof and waterproof performance.

  The shape of the packing end portion according to claim 2 is cut into a slope as shown in FIG. 2 as a shape that matches the end portions of adjacent packings according to claim 1 when they abut each other. Since the cross-sectional area of the packing 7 can be increased and bonding can be performed using an adhesive or the like, the gap between the packings 7 can be surely filled, and the length of the seam 7a can be increased. Even if sucked up, etc., it is less likely to enter the cabinet.

  The shape of the packing end portion according to claim 3 is cut into a step shape as shown in FIG. 3 as a shape that matches the end portions of the adjacent packings according to claim 1 when they abut each other. Since the cross-sectional area of the packing also increases and it is possible to bond using an adhesive or the like, the gap between the packings can be reliably filled, and the length of the seam 7a is increased, so that rainwater, dust, etc. may be generated. Even if sucked up, it is less likely to enter the cabinet.
