Field of industrial application) The present invention relates to a shoulder mount for a new telephone handset. More specifically, it is an object of the present invention to provide a novel shoulder-mounted device for a telephone handset that can be attached to various shaped grips of the telephone handset and that can be hung on the shoulder in a stable state. .

(B. Outline of the Invention) The shoulder strap of the telephone receiver of the present invention allows the base to be attached to the holding portion of the telephone receiver, and to be attached to the holding portions of various shapes. , A main arm rotatable with respect to the base and a sub arm rotatable with respect to the main arm are provided, and the main arm is opened with respect to the base, in other words, with respect to the grip portion of the telephone handset, and ,
Since the sub arm is opened with respect to the main arm and the shoulder is put between the main arm and the sub arm to hold it, the main arm and the sub arm sandwich the shoulder, and the holding state is extremely stable. Becomes

(C. Prior art) [Figs. 12 and 13] When taking notes or searching for materials while talking on the telephone, one hand is blocked to hold the telephone handset. Since it is difficult to perform the above work, it is necessary to bend the neck and hold the handset by sandwiching the grip portion of the handset for telephone with the side face and the shoulder.

However, in order to hold the handset as described above, the neck has to be bent considerably deeply, which results in a very unnatural shape. Therefore, a shoulder strap has been conventionally proposed which serves as an assistant for that. .

FIG. 12 and FIG. 13 show an example a of such a shoulder device.

Reference numeral b is a base, and dowels c, c are provided so as to project from both side surfaces thereof.

Reference numeral d denotes a hooking cord, which is formed by forming coil springs in the shape of a figure 8 and binding them in the central portion.
e is formed.

Reference numeral f denotes a telephone handset of a telephone, and a base b is applied to the back of the grip portion g, a hooking cord d is applied to the abdomen of the grip portion g, and the ring-shaped portions e and e are projected from both sides of the base b. c and c are hooked separately, whereby the base b is attached to the grip portion g of the handset f.

Reference numeral h denotes an arm, the base end of which is rotatably supported by the base b and is opened at an angle of about 90 ° with respect to the base b.

When using, the arm h is opened with respect to the base b, the shoulder is put in the V-shape formed by the back part of the grip part g and the arm h, and the ear is applied to the earpiece. To use.

(D. Problem to be solved by the device) [Figs. 12 and 13] By the way, the above-mentioned conventional shoulder strap a for a telephone handset
In that case, for example, it can be attached only to a fixed shape such as the conventional 600 type. Currently, telephones of various designs are provided, and the shapes of the handsets of the telephones are various, but the hook cord d in the conventional shoulder strap a is used.
However, there is a problem in that the shape and size that can be used are limited, because the material expands only slightly.

Further, since the conventional shoulder hanger a is used by putting a shoulder between the arm h and the grip of the handset, it should be hung on the shoulder unless the shape of the handset is the conventional 600 type or similar. There is a problem that you can not.

(E. Means for Solving the Problem) In order to solve the above-mentioned problems, the shoulder mount of the telephone receiver of the present invention has a main arm that can be pivoted on a base that is detachably attached to the grip of the receiver. The sub-arm is rotatably supported on the main arm so that the turning end is located on the turning end side of the main arm.

Therefore, in the shoulder strap of the telephone receiver of the present invention,
The shape of the handset that can be attached is not limited to one type because it is attached to the handset via the base that is detachably attached to the grip of the handset, and the usable range is Becomes extremely wide. In addition, since the shoulder is placed between the main arm and the sub arm that are opened to each other, the shape of the grip portion of the handset has no meaning when it is hung on the shoulder, and therefore, in this respect also, It becomes possible to use it for a shaped handset.
