Description

[Detailed Description of the Invention] This invention relates to a device for attaching telephone accessories to the back of a telephone.

Conventionally, this type of attachment device has been attached using the back structure of the telephone, but for example, in the case of a conventional telephone commonly known as the 600 type, it will be explained with reference to Fig. 6.
The cross-sectional shape of the recessed shelf z on the back of the phone is in the shape of a square with the open end side being narrower.The recessed shelf z
In order to have a bulge x on the inner side of the end surface of the upper surface y, a recess v is provided on the upper side of the arm w to engage the bulge x. It locks using the repulsive force in the direction. However, in the case of the 601 type telephone shown by the imaginary lines in Figs. 2, 3, and 5, the cross-sectional shape of the concave shelf a on the back of the telephone is a square shape with the open end side wide open. Because of this, the conventional locking structure of the bulging strip x cannot be achieved, and the repulsive force in the upward and downward and/or left and right outward directions often weakens as it is used, making it impossible to lock telephone accessories. The purpose of this project is to provide a low-cost mounting device that can securely and permanently mount telephone accessories, whether it is the 600 model, which is the conventional telephone, or the 601 model, which has a concave shelf Z or a. It is not intended to be provided.

The mounting device according to the present invention will be explained in more detail below with reference to two embodiments shown in the accompanying drawings. Reference numerals 1 and 1 denote two arms, and in the embodiment shown in FIGS. 1 to 3, two arms 1 and 1 are integrally molded from synthetic resin and have a U-shaped planar shape and a forked shape, and FIGS. In the illustrated example, two arms 1, 1 made of metal are shown, which are bent into a planar U-shape. The two arms 1, 1 are not limited to these embodiments as long as they have an abutment part 2 that can be abutted on the inside and an abutment part 3 that can be abutted on the tapered shelf b on the lower surface. The abutment part 2 provided above the husband is abutted on the inner side of the upper surface of a recessed shelf a on the back side of the telephone main body A. The installation part 2 is the first
600 as shown in FIG. 6 for the embodiments of FIGS.
The concave portion v that fits into the bulging strip x of a telephone is also used as a stopper, and in the embodiments shown in FIGS. 4 and 5, the upper sides of the two arms 1, 1 are used. However, the present invention is not limited to these two embodiments as long as it has an abutting portion 2 that can be abutted on the inside of the upper surface of the recessed shelf a on the back of the telephone main body A. Further, the abutting portions 3 provided below each of the two arms 1, 1 are abutted to a tapered shelf b on the back side of the telephone main body A. The relevant part 3 is the first
In the embodiment shown in Figures to Figures 3, each of the two arms 1, 1 is formed with a fork-shaped arm, and the straight lower sides of each of the two arms 1, 1 are forked as shown in Figure 2. The open ends of the lower sides of the two arms 1, 1 shown in FIG. In the embodiment shown in FIG. 5, the lower sides of each of the two arms 1, 1 are tapered toward the end face side, and as shown in FIG. However, the present invention is not limited to these two embodiments as long as the abutting portion 3 can be abutted to the tapered shelf b. In addition, in the embodiment shown in FIGS. 1 to 3, an inverted U-shaped notch c is cut out in the continuous surface between the two arms 1 and 1 to form a structure that repulses outward.
An outward repulsion mechanism 5 is shown in which a slit d is provided on the upper side of the letter shape, and in the embodiments shown in FIGS.
1, the repulsion mechanism 5 is shown in which a U-shaped plate is provided on the base side from half the length of the arm 1, but in this proposal, each of the two arms 1, 1 is biased to repel in the outward direction. The invention is not limited to these two embodiments as long as it is suitable. In both of these embodiments, the friction element 4 is made of synthetic rubber with a T-shaped cross section and a hollow center, and is attached to the outer surface of each of the two arms 1, 1 on the root side. two arms 1, two arms 1 acting outwardly on one or more sides of 1;
It is sufficient to attach a friction element 4 having a larger coefficient of friction than each of the two arms 1, 1, and the repulsive force of the two arms 1 and the husband of 1 is made stronger than in the illustrated embodiment, or If the lateral repulsive force of the arms 1, 1 is strong, it is sufficient to attach the friction element 4 to only one of the arms 1, 1 and set the two arms 1, 1 to a specific position in the lateral direction. The examples are not limited. B in the figure shows accessories for the telephone.

In this case, as mentioned above, the abutting part 2 is provided above and the abutting part 3 is provided below each of the two arms 1, 1 that repel outwardly, and the abutting part 2 is attached to the back of the telephone main body A. Provided so as to be placed on the inside of the upper surface of the concave shelf a,
Also, attach the installation part 3 to the taper shelf B on the back of the phone body A.
Since a friction element 4 made of rubber or the like that acts in an outward direction is provided on the side surface of one or more of the arms 1 and 1 on the base side, the mounting device of the present invention can be mounted on the telephone body A. , insert the two arms 1, 1 that repel outwardly into the recessed shelf a of the telephone main body A against the repulsive force, and insert the abutting portions 2 of the two arms 1, 1, respectively. The concave shelf a is brought into contact with the inside of the upper surface, and the respective contact portions 3 of the two arms 1 and 1 are brought into contact with the tapered shelf b on the back of the telephone body A, and one or more of the arms 1 The installation is completed by bringing the friction element 4, such as rubber, provided on the side surface of the main body into contact with the side wall surface e on the back of the telephone main body A.

In this case, as described above, the two arms 1, 1 repelling outwardly cause the respective abutting portions 2 of the two arms 1, 1 to form the abutting portions 3 on the inner side of the upper surface of the recessed shelf a. A synergistic frictional effect in the vertical direction is applied to the tapered shelf b along with the load of the telephone accessory B, and furthermore, the friction of rubber etc. provided on the side surface of the two arms 1 and one or more of the arms 1 on the base side is applied. The child 4 cooperates with the repulsive forces of the two arms 1, 1 that repel outward and laterally, and presses against the side wall surface e on the back of the telephone body A, resulting in a vertical and horizontal friction mechanism and a synergistic effect. It acts firmly and securely. In addition, in this case, since the friction element 4 made of rubber or the like is provided on the base side of one or more of the two arms 1, 1 that repel outward, the two arms 1, 1 can be replaced with a metal such as synthetic resin. If an elastic material with a relatively short service life is used than that made of natural materials, even if its elasticity weakens, the friction element provided at the base of the arm 1 will not be restrained by the repulsive force in the outward direction and will continue to exert frictional action. This can significantly extend its useful life. In addition, in this case, the locking mechanism can be installed without using the structure of the telephone main body A, that is, the locking structure that locks on the bulging strip x shown in FIG. 6, as in the conventional 600 type. As long as the back of the phone main body A has a recess a, a tapered shelf b, and a side wall e, any conventional type can be installed, and it can be attached to the back of the phone main body A without the two arms that rebound outward. 1, 1, it is possible to install the proposed structure, and there is a practical benefit of being able to provide it at a low cost.
