Description

[Detailed Description of the Invention] [Summary] In a telephone configured to be both a tabletop type and a wall-mounted type, the wall-mounted handset has a hook structure that prevents the handset suspended from the telephone body from slipping off, and is low-cost. In addition, the aim is to provide a hook structure that makes it easy to switch between a tabletop and a wall mount.The wall mount that is attached to the phone body has a hook that is inserted into a hook attachment recess provided on the phone body, and a hook body that is inserted into the hook attachment recess provided on the phone body. It consists of a connected hook piece whose key-shaped tip engages with the jaw of the handset, and on the left and right sides of the hook body,
Provide a shoulder. On the other hand, a pair of protrusions are provided on the left and right inner walls of the hook attachment recess, corresponding to the shoulders.

Then, fit the hook body into the hook mounting recess, shift it in the desired direction, engage the shoulder with the protrusion, and then fit the hook cover into the opening of the hook mounting recess, so that the wall hanging can be done using the hook. The structure is such that it is fixed to the phone body.

(Industrial Field of Application) The present invention relates to a telephone configured to be both a tabletop type and a wall-mounted type, and particularly relates to a wall-mounted hook structure of the handset that prevents the handset suspended from the phone body from slipping off.

As shown in FIG. 4, a general telephone includes a handset 3 with a receiver 4 on the top of the handle and a transmitter 5 on the bottom, and a phone main body 2.
and handset 3 are connected with a flexible cord.

In order to hang the handset 3 on the phone body 2, attach it to the rear side of the upper case 2B of the phone body 2 (the wall hanging is on the top side).
A receiver recess 6 is provided to accommodate the receiver 4 portion, and a transmitter recess 7 is provided on the front side of the upper case 2B (lower side when wall-mounted) to accommodate the transmitter 5 portion.

The telephone 1 can be used as a tabletop by placing a pedestal (not shown) on the bottom of the lower case 2A of the telephone main body 2, or by attaching a hook to a wall etc. It can also be used as a wall hanging by hooking the notch provided in the lower case 2A.

When using the telephone 1 as a wall-mounted device, the receiver 4 portion of the handset 3 is inserted into the receiver recess 6 of the telephone body 2.
However, if the handset 3 is only suspended on the telephone main body 2 by housing the transmitter 5 in the transmitter recess 7,
There is a risk that the handset 3 may slip off the telephone body 2.

Therefore, a recess for attaching a hook is provided below the handset recess 6 (on the front side when installed on a tabletop), and a hook 10 for wall hanging is fitted into this recess. The jaw 4A of the telephone receiver 4 is hooked onto the piece to prevent the handset 3 from falling.

Note that when the telephone 1 is used as a tabletop type, the hook 10 on the wall becomes an obstacle to picking up the handset 3. Therefore, when the telephone 1 is used as a tabletop type, the hook 10 is removed from the wall, or the telephone 1 is housed inside the telephone body.

(Prior Art) FIG. 5 is a perspective view showing a hook structure of a conventional wall hanging, and shows a receiver recess 6 provided in the upper case 2B of the telephone main body 2.
A hook attachment recess 30 in the form of a square hole with a bottom is provided on the front side (the lower side when wall-mounted), and a pair of engagement holes 32 are provided in the portions of the hook attachment recess 30 close to the left and right inner walls of the bottom plate. This is provided.

Furthermore, a key-shaped window 33 is provided from the inner wall on the front side of the hook mounting recess 30 to the bottom plate, and a small screw for fixing the wall hook 10 is provided in the center of the bottom plate of the hook mounting recess 30. 40 is provided with a screw hole 31 into which it is screwed.

10 is a rectangular cylinder-shaped hook body 11; and a hook body 1;
The wall hanging consists of a rear side plate 1 extending upward and a hook piece 12 bent rearward (upwards in the wall hanging) in a key shape, and is a hook, which is a molded product.

The hook main body 11 has an L shape so as to be completely fitted into the hook mounting recess 30, and its height is smaller than the depth of the hook mounting recess 30 by the thickness of the cover main body 21. With the hook body 11 fitted into the hook attachment recess 30, the hook piece 12 projects upward from the surface of the upper case 2B.

A hole 13 is provided in the core of the hook body 11 into which the neck of the machine screw 40 is temporarily inserted, and after the hook body 11 is inserted into the hook mounting recess 30, the machine screw 40 is inserted into the hole 13 and the threaded hole 31 is inserted. For wall hanging, attach the hook 10 to the phone body 2.
It is fixed at

As mentioned above, the wall hanging is done by attaching the hook 10 to the phone body 2, so when the phone body 2 is attached to the wall and the phone is used as a wall hanging, the wall hanging is done by attaching the hook 10 to the phone body 2.
The tip of No. 2 faces upward.

Therefore, when the handset part is accommodated in the handset recess 6 and the handset is suspended on the telephone main body, the jaw of the handset is caught and locked by the tip of the hook piece 12, and the handset does not slip off from the telephone main body.

However, as mentioned above, for wall hanging, hook 10 is hook 1;

When the hook is attached to the attachment recess 30, the upper surface of the hook body 11 is exposed, which is unsightly.

Therefore, the opening of the hook mounting recess 30 is closed with the hook cover 20 to improve the appearance and increase the commercial value.

Hook cover 20 molded from elastic synthetic resin
The cover body 21 has a predetermined rectangular shape that fits into the upper part of the opening of the hook attachment recess 30, and a claw 2 that protrudes downward in a U-shape from both side edges of the cover body 21, and has claws 2 at the tips of each.
It consists of a pair of leg pieces 22 having a diameter of 3.

Therefore, the hook 10 cannot be hung on the wall in the hook mounting recess 30.
When the hook cover 20 is inserted into the hook attachment recess 30, the lower surface of the cover body 21 comes into contact with the hook upper end surface 15 of the hook body 11, and in this state, the hook cover 20 is inserted into the hook attachment recess above the hook body 11. 30, the opening of the hook attachment recess 30 is closed by the cover body 21, resulting in a good appearance.

Further, in the state where the cover body 21 is fitted, the claws 23 of the leg pieces 22 are respectively engaged with the engagement holes 32 provided in the bottom plate of the hook attachment recess 30. Therefore, even if the telephone main body 2 vibrates or receives an impact, there is no fear that the hook cover 20 will fall off from the telephone main body 2.

In addition, when the telephone is used as a tabletop type, the hook piece 12 becomes an obstacle to the operation of the handset, so it is necessary to remove the hook 10 from the wall.

To remove the wall hook 10, insert a pin or the like into the notch of the cover body 21, remove the hook cover 20, and then loosen the machine screw 40 to remove the wall hook 10 from the telephone body.

Then, for wall hanging, turn the hook 10 upside down so that the hook piece 12 fits into the window 33 provided in the hook mounting recess 30.
It is inserted and stored in the hook mounting recess 30, and then the hook cover 20 is fitted.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional wall hanging structure, a screw hole 31 is provided in the bottom plate of the hook mounting recess 30 of the upper case 2B in order to secure the hook 10 to the telephone main body 2. In general, directly providing a tapped hole in a plastic product not only requires a complicated mold structure and high cost, but also has low strength of the molded thread. Therefore, conventionally, a metal column with a screw hole in the shaft center is insert-molded into the bottom plate of the hook mounting recess 30, and the screw hole 31 is inserted into the bottom plate of the hook mounting recess 30.
