Abstract

PURPOSE:To obtain the structure of a gate to be opened in any direction out of the front and back directions. CONSTITUTION:The disk 3 is pivoted by the frames 5, 6 of a disk at its 1st side edge 7 in the vertical direction and can rotate on a circular arc-like route formed by setting up the 2nd side edge 9 as a free end, and on a normal position covering the rear side of the disk, the 2nd side edge 9 is constituted so as to be opposed to a pole member 10 constituting a part of the frames of the disk with a small gap. A common auxiliary plate covering the 2nd side edge 9 and the pole member 10 is prepared so as to be fixed/released to/from both the members 9, 10 and either one of the member 10 and the side edge 9 is released from the plate so as to rotate the gate 3 only in either one of the front and back directions through the member 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay stand for performing a line connection operation in a telephone exchange, and more particularly to a novel structure of a gate installed in the lower space thereof.

[0002]

2. Description of the Related Art As shown in FIG. 5, a relay stand is composed of a desk 2 on which an operating device 1 is placed, and a circuit package for signal processing, a terminal device and an external device are provided in the lower space of the desk. A gate 3 having a terminal board, a connector, etc. mounted on both sides for connection with a line is attached. This gate 3 has a hinge axis Z attached to one side edge so that these parts can be easily accessed for maintenance and inspection.
The structure is such that it can be opened forwardly to the position shown in the figure around the center, and when it is not opened, the other side edge of the gate that overlaps with the pillar member of the desk frame is fixed to the pillar member by a screw or the like.

[0003]

The relay stand is often installed facing the wall, or two stand back to back. In such a case, there is no space for opening the gate on the back side. The fact is that such a front-opening gate structure is adopted. However, if the relay stand is installed in a place where there is extra space on the back side of the desk, if the gate can be opened on the back side, the worker does not have to go under the narrow desk for maintenance and inspection. Therefore, workability is improved.

It is an object of the present invention to provide a structure in which the gate can be opened in either the front or rear direction, if necessary, in response to such a demand.

[0005]

This object is to install a desk on which an operation panel is placed and parts such as a circuit package, a terminal board, and a connector on both sides, and to cover the back side of the desk. A rectangular panel-shaped gate, the first side edge of which is perpendicular to the frame of the desk, and the gate is rotatable in an arcuate path having the second side edge as a free end. At a normal position covering the back side of the desk, in the relay stand of the telephone exchange, the second side edge is configured to face a pillar member forming a part of the desk frame with a slight gap. A common auxiliary plate that straddles the second side edge and the pillar member is provided, and the auxiliary plate is fixed and releasable with respect to each other. By fixing the auxiliary plate to both, the gate is in the normal position. To the auxiliary plate By fixing it to one side and releasing it from the other, it is possible to rotate the gate with respect to the pillar member only in one of the front and rear directions, and by reversing the fixing and releasing, it is possible to rotate only in the opposite direction. This is achieved by a gate structure characterized by what is done.

[0006]

[Function] When maintenance / inspection work is not performed, if the auxiliary plate is fixed to both the gate and the pillar member, the gate is maintained in the normal position and covers the opening on the back of the desk. .. When performing maintenance / inspection work, by releasing the auxiliary plate from either the gate side or the pillar member side, the rotation blocking direction as the stopper of the auxiliary plate is selected, and the relay stand is installed. The gate can be rotated in the direction with the best workability according to the location conditions of the place.

Based on the preferred embodiment shown in the drawings,
The present invention will be described in more detail.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a main part of a gate structure of a relay stand according to the present invention, and as described above with reference to the drawings, it is installed on the back side of an operation desk of the relay stand. The gate 3 includes a beam 5 extending in the width direction of the desk and a pedestal 6 installed at the bottom.
Between the one side edge (hereinafter referred to as the first side edge 7)
The upper and lower parts of the above are pivotally supported by the pin 8, and the other side edge (hereinafter referred to as the second side edge 9) is used as a free end to rotate in an arcuate path.

The second side edge 9 is shown in FIG. 2 when the gate 3 occupies a normal position covering the opening on the back surface of the desk.
As will be described in detail later, it is configured so as to face the column member 10 forming a part of the frame of the desk with a slight gap S. Then, in a region where the second side edge 9 of the gate 3 and the pillar member 10 face each other, an auxiliary plate 11 extending in the up-and-down direction extends its width across the gate 3 and the pillar member 10. , And are fixed to both by neck screws 12 and 13, respectively. As a result, the gate 3 is maintained and fixed in the normal position that covers the back opening of the desk.

Since the auxiliary plate 11 is fixed by the screws 12 and 13 with necks, it can be easily detached from the gate 3 or the pillar member 10 and released from the restraint of these members by loosening it. It is possible. In FIG. 3, the auxiliary plate 11 is removed from the gate 3 to remove the pillar member 1.
The state left on the 0 side is shown. In this case, the auxiliary plate 11
Serves as a stopper to block the gate 3 in the direction of arrow A, and only the rotation in the direction of arrow B, that is, the opening of the desk to the front side is allowed.

On the other hand, FIG. 4 shows a state in which the auxiliary plate 11 is removed from the pillar member 10 and left on the gate 3 side. Contrary to the above, the pillar member 10 functions as a stopper for the auxiliary plate 11, Only rotation in the direction of arrow A is allowed. The selection of such a turning direction is determined by the location conditions of the place where the relay stand is installed, and when there is enough space for an operator to enter on the back side, the gate is turned in the A direction, that is, the back side of the desk. The auxiliary plate 11 may be left on the gate side as much as possible to facilitate maintenance work. On the contrary, when the front side of the desk has a sufficient space, the auxiliary plate 11 may be left on the pillar member side.

[0012]

According to the present invention, by providing a detachable auxiliary plate, it is possible to arbitrarily select the turning direction of the gate with the same mechanism. It becomes possible to perform maintenance / inspection work by opening the door and improve efficiency.
