JP5553342B2 - Structure to prevent the door from falling down in the cabinet - Google Patents

Description

  The present invention relates to a structure for preventing a door that can be opened and closed in a lateral direction from falling down in a cabinet that houses electrical equipment and the like.

  Conventionally, a cabinet as shown in FIG. 5 is known (Patent Document 1). In this cabinet 51, a door 53 is pivotally attached to a housing 52 by a hinge 54 so that the door 53 can be opened and closed in the lateral direction, and a handle 55 is attached to the door 53 opposite to the hinge 54. Then, pins 56 are erected at the four corners of the inner surface of the door 53, holes 57 are formed at the four corners of the opening of the housing 52, and when the door 53 is closed, the pins 56 are inserted into the holes 57, It is designed to prevent falling down.

Japanese Patent Laid-Open No. 2003-8251

  However, according to the conventional cabinet 51, in order to prevent the door 53 from falling down, it is necessary to provide four pins 56 and process four holes 57, which increases the number of parts and man-hours, and the manufacturing cost is high. There was a problem of sticking. In addition, since there are four fitting portions, when the housing 52 is distorted by a step such as a wall surface, any pin 56 does not fit into the hole 57 or contacts the periphery of the hole 57. The door 53 could not be opened and closed smoothly.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a cabinet that can prevent a door from falling down with a simple and inexpensive structure and can smoothly open and close the door.

  In order to solve the above-mentioned problems, the cabinet of the present invention is pivotally attached to the housing so that the door can be opened and closed in the lateral direction, and a handle is attached to the door on the side opposite to the pivotally attached portion. Provided with a positioning part, and an engaging part is formed in the door near the handle, and when the door is closed, the engaging part engages with the positioning part, and the positioning part positions the door in the vertical direction. To do.

The present invention provides the following means in the cabinet.
(A) A positioning part is provided on the housing so that the height can be adjusted.
(B) A door side latch that is latched to the housing side latch by the operation of the handle is provided, an engaging portion is formed in the vicinity of the door side latch, and a positioning portion is provided in the vicinity of the housing side latch.
(C) The positioning portion includes a head portion of a bolt for attaching the housing side latch to the housing, and the door side engaging portion includes a notch that fits into the head portion of the bolt when the door is closed.

  According to the cabinet of the present invention, since the engagement portion between the door and the housing is limited to the vicinity of the handle, the number of parts and man-hours can be reduced, and the door can be prevented from falling down with a simple and inexpensive structure. Further, since the engaging portion and the positioning portion are disposed in the vicinity of the handle, the door can be opened and closed smoothly without applying an excessive force to the pivoting portion or the like.

It is a front view of the cabinet which shows one Embodiment of this invention. It is a perspective view which shows a cabinet in the state which opened the door. It is a perspective view which expands and shows the engaging part of a housing and a door. It is a front view which shows the cabinet when a housing is deform | transforming. It is a perspective view which shows the conventional cabinet.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the cabinet 1 of this embodiment includes a housing 2 that houses electrical equipment and a door 3 that covers a front opening 2 a of the housing 2. The housing 2 is formed in a rectangular thin box shape, and a mounting substrate 4 for electrical equipment is attached to the inside. The door 3 is pivotally attached to one side frame 2 b of the housing 2 by a hinge 5 so as to be openable and closable in a lateral direction, and a handle 6 is attached to the front surface of the door 3 on the side opposite to the hinge 5.

  In the vicinity of the handle 6, a door side latch 7 is provided inside the door 3. The door side latch 7 is coupled to the handle 6, and is latched to the housing side latch 8 by the turning operation of the handle 6. The housing side latch 8 is attached to the other side frame 2 c of the housing 2 with a bolt 9 at the same height as the handle 6. Two bolts 9 are screwed into the housing side latch 8 via the long hole 10 of the side frame 2c, and the height of the bolt 9 with respect to the housing 2 can be adjusted.

  As shown in FIGS. 2 and 3, two notches 11 are formed on the side edge 3 a of the door 3 in the vicinity of the door side latch 7. And when the door 3 is closed, the notch 11 as an engaging part fits into the bolt head 9a which is a positioning part, and the bolt head 9a positions the door 3 in the vertical direction. In the embodiment shown in FIG. 3, the bolt head portion 9a is formed in a tapered cylindrical shape, and the notch 11 is formed in a semicircle having substantially the same diameter as the maximum diameter portion of the head portion 9a.

According to the cabinet 1 having the above configuration, the following operational effects can be obtained.
(1) Since the fitting portion between the housing 2 and the door 3 is limited to two places near the handle 6, the number of parts and man-hours can be reduced, and the door 3 can be prevented from falling down with a simple and inexpensive structure.
(2) Since the bolt head 9a and the notch 11 which are fitting parts are disposed in the vicinity of the handle 6, the notch 11 is fitted into the bolt head 9a without applying an excessive force to the hinge 5 or the like. The door 3 can be opened and closed smoothly.

(3) As shown in FIG. 4, when the housing 2 is distorted by a step such as a wall surface on which the cabinet 1 is installed, the height of the bolt 9 is adjusted up and down along the long hole 10. Thus, the notch 11 can be fitted to and removed from the bolt head 9a without tilting the door 3.
(4) Since the engagement portion on the door 3 side is the notch 11 and the bolt 9 for attaching the latch 8 is used as the positioning portion on the housing 2 side, the door 3 can be prevented from falling down with fewer parts.

  In addition, this invention is not limited to the said embodiment, For example, fitting the convex part by the side of the door 3 to the concave part by the side of the housing | casing 2, or applying to the cabinet which accommodates a tool or machinery etc. The shape or configuration of each part can be changed as appropriate without departing from the spirit of the present invention.
