Abstract

PURPOSE:To provide a multiply connected keys; the interval of which can be narrowed. CONSTITUTION:Connected keys are provided with a key group, hinges 21, 22 for elastically supporting each key of the key group, and frame bodies 31, 32 for fixing the hinges. Two formed bodies (a), (b) are formed, for which a key 11 or 12 placed another line in the group, the hinge 21 or 22 for supporting the key, and the frame body 31 or 23 for fixing the hinge, respectively, are formed in an integrated manner, and the formation bodies are superimposed on one another (c) so that the keys are placed on the same flat surface. The degree of freedom for interval between adjacent keys 11, 12 is increased, while setting of the key interval according to the design of a device, in which the key group is to be fitted, is thus made possible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ten-key pad for a telephone or the like, and more particularly to a ten-key pad which can be arranged close to each other.

[0002]

2. Description of the Related Art A conventional telephone, as shown in FIG. 3, has a portion (numerical key portion) 4 where dial keys and function keys are assembled. When the telephone cabinet 5 is removed, the ten-key portion 4 has a structure in which each of the keys 1 is supported by two thin hinges 2 extending from the eye-shaped frame 3 as shown in FIG. The frame 3, the hinge 2, and the keys 1 are integrally formed. When pressed, each of the keys 1 moves against the elasticity of the hinge 2, and when released, the elasticity of the hinge 2 causes the keys 1 to return to their original positions.

A large number of keys (multi-connecting keys) configured by connecting in this way have a smaller number of parts than a method of individually attaching each key, and a positioning jig for attaching each key is used. Since it is not necessary and has many advantages in parts management and work, it is the mainstream of the current telephone.

[0004]

However, in the conventional multi-connecting key, the interval between the keys cannot be narrowed to a certain extent or more. As shown in FIG. 5 by enlarging the portion A in FIG. 4, this is the key between the key 11 and the adjacent key 12.
The total length d (= 2d1 + 2t + d) of the distance d1 between 11 and the hinge 21, the width t of the hinge 21, the distance d2 between the hinge 21 and the hinge 22, the width t of the hinge 22 and the distance d1 between the hinge 22 and the key 12.
This is because 2) is absolutely necessary.

Therefore, even if an attempt is made to design a telephone having a narrow key interval, such a technical point is a limitation and it cannot be executed.

In order to realize this, if the keys are attached to the cabinet one by one, the number of parts is increased, and a positioning jig for attaching each key is required. The harmful effect above is too great.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a multi-connecting key which can make the key interval narrow and, in some cases, widen it.

[0008]

Therefore, in the present invention, in a multi-connecting key including a key group, a hinge for elastically supporting each key of the key group, and a frame body for fixing the hinge, Form two molded bodies that are formed by integrally molding the keys of every other group of keys, the hinge that supports this key, and the frame that fixes this hinge, and place each of these molded bodies on the same plane. Are overlaid.

[0009]

As a result, the degree of freedom with respect to the space between adjacent keys is increased, and according to the design of the device in which the key group is mounted,
It becomes possible to set the key interval.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The multi-connection key in the embodiment of the present invention is shown in FIG.
As shown in FIG. 1, the ten-key pad is divided into two molded bodies (a) and (b), which are combined and configured as shown in FIG. 1 (c).

Each of the molded bodies (a) and (b) is a frame-shaped frame 3
Thin hinges 21 and 22 extending from 1 and 32 support the keys 11 and 12 arranged in a row on the numeric keypad portion. In each of the molded bodies of (a) and (b), the frame, the hinge, and the key are It is integrally molded.

As shown in FIG. 1C, the frame bodies 31 and 32 of (a) and (b) are overlapped with each other, and a hinge 21 connected to the frame body 31 and a hinge 22 connected to the frame body 32 are provided. Combine so that they overlap when viewed from the front. However, hinge 21 and hinge
In the front-rear direction with respect to the frame 22, the frame bodies 31, 32 of the hinges 21, 22 are arranged so that the movable front hinge 22 has a space not to touch the rear hinge 21 when the key 12 is pressed. Set the mounting position on the.

The length between the key 11 and the adjacent key 12 in the combined multi-joint key is as shown in FIG. 2 which is an enlarged view of the portion B of FIG. twenty one
The distance d1 between the hinge 21 and the width t of the hinge 21 (22) and the distance d1 between the hinge 22 and the key 12 are the combined length d (= 2d1 + t), which is larger than the key spacing of the conventional multi-connecting key (Fig. 5). , The width t of the hinge and the distance d2 between the hinges are shortened.

As described above, in the multi-joint key of the embodiment, the key group forming the numeric keypad is divided into two parts, and by combining them, the setting of the key interval is more flexible than in the conventional case. You can have a degree. Therefore, with this multi-connection key, the key interval can be made narrower than before, and in addition to that, the key interval can be expanded according to the design of the telephone.

Of course, this multi-connection key can be used as a key group in a device other than a telephone.

[0016]

As is apparent from the above description of the embodiments, in the multi-connecting key of the present invention, the key interval can be freely set according to the design of the device to which it is attached.
