Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eject handle used for a unit mounting board.

[0002]

2. Description of the Related Art An eject handle used in a conventional unit mounting board will be described with reference to FIGS.

In FIGS. 5 and 6, reference numeral 1 is an eject handle, which is formed of a flat plate having a Y shape in plan view,
A portion corresponding to the upper side of the Y-shape (hereinafter referred to as the shaft support) 2
Is provided with a through hole 5 through which a shaft 4 hung vertically on the board 3 is inserted, and a columnar pressing portion is provided at the tip of a portion (hereinafter referred to as a lever portion) 6 corresponding to the other upper side of the Y-shape. 7 is fixed. The portion corresponding to the lower side of the Y-shape is the handle portion 8. The eject handle 1 is rotatably supported by making a handle portion 8 inward and passing a shaft 4 vertically provided at both front ends of a board 3 through a through hole 5 of a shaft support portion 2.

On the board 3 to which the eject handle 1 is attached, a bracket 10 for attaching the connector 9 which is cut out from the fixing portion of the eject handle 1 is vertically installed, and the board 3 is inserted into the slot of the unit 11 to support it. Has been done.

The work of mounting and withdrawing the board 3 will be described. At the time of pulling out, put your fingers on the handle portions 8 of both eject handles 1 and pull it toward you. Then,
The pressing portion 7 at the tip of the lever portion 6 comes into contact with the unit 11,
Due to the principle of leverage, as the eject handle 1 rotates, the board 3 is pushed forward, as shown by the two-dot broken line in FIG. 5, so that the board 3 can be pulled out.

In addition, at the time of mounting, the positions of both the handle portions 8 are returned to the inside, and the handle portions 8 are pressed with fingers. Then the board 3 is inserted inside the unit 11,
Can be installed.

[0007]

However, in the above-described conventional eject handle 1, the length L is long, the long notch 10A is required in the bracket 10, and the cable 12 attached to the connector 9 and the handle portion. Connector 9 and eject handle 1 for inserting a finger between
Since the distance α is required between the and, the component mounting area on the bracket 10 is limited, the size of the connector 9 is limited, and the number of input / output points of the board 3 determined by the connector 9 is limited. There was a problem of limiting the design of the board 3. In particular, when it comes to a highly mounted board, there is a problem that its design becomes difficult. Further, since the mounting area of the components on the bracket 10 is limited, the mounting area of not only the connector 9 but also an indicator such as a lamp and a switch is also limited, which limits the design of the board 3.

The present invention solves the above problems,
An object of the present invention is to provide an eject handle capable of increasing the mounting area of components on a bracket.

[0009]

In order to solve the above problems, an eject handle of the present invention is an eject handle for pulling out a board, which is attached to both ends of a board on which brackets for attaching components are suspended. With a handle portion, a plate-shaped lever portion having a protruding portion whose tip comes into contact with the mounting unit of the board and a plate-shaped shaft supporting portion having a through hole for passing a shaft vertically provided at the end portion of the board are provided by a handle portion. It is characterized in that a part of them are overlapped and fixed in parallel.

[0010]

With the above construction, the shaft support portion and the lever portion are partially overlapped and supported in parallel, and the length of the eject handle becomes shorter than that of the conventional eject handle, so that the mounting area of the component to be mounted on the bracket is reduced. Will increase.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. It should be noted that the same components as those of the conventional example shown in FIGS.

FIG. 1 is a perspective view of a pair of left and right eject handles in an embodiment of the present invention, and FIGS. 2 to 4 are a partial plan view, front view and perspective view of a board to which the eject handles are attached.

FIG. 1 (a) shows an eject handle 21A attached to the left side of the board of the present invention, and FIG. 1 (b) shows an eject handle 21B attached to the right side of the board of the present invention. These eject handles 21A and 21B are They are formed symmetrically with each other. Eject handle 21A, 21B of the present invention
The handle portion includes a flat plate-shaped shaft support portion 23 having a through hole 22 for passing the shaft 4 vertically provided on the board 3, and a flat plate-shaped lever portion 24 which is rotated when its tip comes into contact with the frame of the unit 11. Part of the lever portion 24 is overlapped and fixed in parallel vertically by 25 so that the tip of the lever portion 24 projects. In the eject handle 21 of the present invention, the shaft support portion 23 is located downward, and a part of the eject handle 21 is projected in the same shape as the projecting portion 24A of the lever portion 24 (projecting portion 23A).
At a position facing 25, these protrusions 23A and 24A are vertically connected by a connecting portion 26 to enhance the strength of the lever portion 24. In addition, a triangular locking plate 27 that restricts the rotation of the eject handle 21 so that the handle portion 25 is caught by a finger.
Is fixed to the handle portion 25 in parallel above the lever portion 24,
Further, a groove 25A is vertically provided at a side position where a finger is hooked, and a depression 25B is provided on the surface of the handle portion 25. The left eject handle 21A projects the lever portion 24 leftward, and the right eject handle 21B projects the lever portion 24 rightward.

Each of the left and right eject handles 21A and 21B has a handle portion as shown in FIGS.
The position of 25 is inward, and the shaft 4 is rotatably supported by passing it through the through hole 22 of the shaft support portion 23 on the shaft 4 vertically provided at both front ends of the board 3.

The work of mounting and pulling out the board 3 will be described. When pulling out, both eject handles
Put your finger on the handle 25 of 21 and pull it toward you. Then,
The tip of the lever portion 24 (protruding portion 24A) comes into contact with the unit 11,
Due to the principle of leverage, the board 3 is pushed forward as shown by the two-dot broken line in FIGS. 2 and 4, so that the board 3 can be pulled out.

In addition, at the time of mounting, the positions of both the handle parts 25 are returned to the inside, and the handle parts 25 are pressed with fingers. Then the board 3 is inserted inside the unit 11,
Can be installed.

With such a configuration, the eject handles 21A and 21B of the present invention have a shorter length L'compared to the conventional eject handle, so that the notch portion of the bracket 10 is formed as shown in FIG. 10A can be reduced, the mounting area of components on the bracket 10 can be increased, the size of the connector 9 can be increased, and the number of input / output points of the board 3 determined by the connector 9 can be increased. The degree of freedom in design can be increased.

Although the connector 9 is mounted on the bracket 10 in this embodiment, parts such as a display lamp, a digital display and a digital switch may be mounted. Also in this case, since the mounting area is increased, many components can be mounted and the degree of freedom in designing the board 3 can be increased.

[0019]

As described above, according to the present invention, the length of the eject handle is shorter than that of the conventional eject handle because the shaft support portion and the lever portion are partially overlapped and supported in parallel. Therefore, the mounting area of the component mounted on the bracket can be increased, and when the component is a connector, the number of input / output points of the board determined by the size of the connector can be increased, and the degree of freedom in board design can be increased. .
