Description

[Detailed Description of the Invention] This invention relates to a handset/receiver feeder adapter that is attached to a handset/receiver coupler so that it can be used commonly for two or more types of handsets with different shapes.

In recent years, computers, etc. are connected using communication circuit lines, etc.
Data communication is becoming popular, and data communication is generally performed by acoustically coupling a communication modem and a communication circuit line via a telephone handset. As a device, a device configured to transmit an audio signal generated from a telephone to a microphone is known.

Figure 1 shows the handset/receiver coupling part of this type of coupler that has been used in the past.To explain this in the figure, on the board 1 bent in a dogleg shape, there is a rubber or soft Transmitter/receiver receivers 2 and 3 made of synthetic resin are screwed onto the transmitter/receiver receivers 2 and 3, and the transmitter/receiver port 4a and receiver port 4b of the handset 4 are fitted into these receivers 2 and 3, respectively. There is.

Then, signals are sent and received in the form of sound to the transmitter mouth 4a through the speaker 5 attached to the transmitter/receive receiver 3, and from the receiver mouth 4b to the microphone 6 attached to the transmitter/receive receiver 2.

On the other hand, the handset 4 used for this type of data communication is a so-called 600 type handset, which has been widely used in the past, and FIG. 2a shows its front view.
Similarly, b is a plan view.

In the figure, 4a is a speaker mouthpiece, and 4b is a receiver mouthpiece.

However, recently, various types of decorative telephones other than the 600-inch telephone have become popular in households, and all of these telephones are significantly different in shape from the 600-inch telephone.

3 and 4 respectively show front and plan views of handsets 7 and 8 of different types of decorative telephones, and there are other decorative telephones with different shapes.

In these handsets 7, 8, etc., the distance between the lower handsets a, 8a and the lower handsets b, 8b is approximately 600 mm.
It is the same as the handset 4 of the model, but its shape is similar to that of the handset 7.
The transmitter/receiver receivers 2 and 3 for the 600 model cannot be used because the transmitter/receiver receivers 2 and 3 are square in shape, as shown in FIG.

Therefore, there is an inconvenience in that a dedicated transmitter/receiver receiver or coupler that is compatible with the shapes of various handsets and receivers must be used.

The present invention was developed in view of the above points, and the outer circumferential surface of the lower half fits into the receiver and receiver of a general-purpose telephone, and the receiver and receiver of a decorative telephone fits into the inner circumferential surface of the upper half. To provide a handset/receiver coupler adapter which is integrally shaped from a flexible material such that one type of handset/receiver coupler can be used in common for two or more types of handsets/receivers having different shapes. It is something.

Hereinafter, its configuration and the like will be explained in detail with reference to embodiments shown in the drawings.

5 to 7 show a handset/receiver coupler adapter according to the present invention, FIG. 5 a is a plan view thereof, and FIG.
FIG. 6 is a sectional view, FIG. 6 is a perspective view, and FIG. 7 is an exploded perspective view showing how the handset and receiver are connected through the adapter.

In these figures, the adapter 11 is integrally molded from a soft synthetic resin, and has a receiving part 11a with a ring-shaped cross section that opens downward, and a receiving part 11a that communicates with the receiving part 11a and extends above the receiving part 11a. The fitting portion 11b is formed into a ring shape with a rectangular cross section.

The shape of the outer peripheral surface of the receiving portion 11a is such that it fits into the transmitting/receiving cover holder for a 600 type telephone, which is a general-purpose telephone shown in FIG. It is formed like this.

The inner peripheral surface shape of the fitting portion 11b is similar to that of the lower transmitter a and the lower receiver b of the handset 7 of the decorative telephone set shown in FIG.
It is formed to fit with the

As shown in FIG. 7, the adapter 11 configured as described above has its receiving part 11a fitted into the dish-shaped part of the transmitting/receiving cover holder 2, and the fitting part 11b of the adapter 11 has a decorative telephone The handset lower b of the handset 7 of the receiver is inserted.

Since the adapter 11 and the transmitter/receiver cover holder 2 are made of soft synthetic resin, they are in close contact with each other, and the handset 7 is also in close contact with the adapter 11, so that the sound insulation is extremely good.

Although FIG. 7 shows only the receiver lower b side of the receiver 7, the same applies to the receiver mouth side.

8a, l), c, and d all show other embodiments of the present invention, in which a thin ring-shaped fin 11C is integrally formed at the lower end of the adapter 11, and b In this case, a plurality of annular protrusions 1 are formed on the inner peripheral surface of the fitting part 11b.
1 d are integrally formed.

Further, in C, a plurality of annular protrusions 11e are integrally formed on the outer peripheral surface of the receiving part 11a, and in d, a thin ring-shaped fin 11f is formed on the periphery of the upper opening of the receiving part 11a. are integrally formed.

The adapters 11 shown in a, l), c, and d are as follows:
The action of the fins 11C, llf or the annular protrusion 11e improves the adhesion between the handset and the handset/receiver cover holder, thereby further improving sound insulation.

In each of the above embodiments, the adapter used for the decorative telephone 7 shown in FIG. 3 has been described, but for the decorative telephone 8 shown in FIG. 4 and other decorative telephones, the shape of the inner peripheral surface of the fitting portion 11b is The mounting method and effect are the same as in each of the above embodiments, except for the following.

As is clear from the above description, according to the present invention, there is provided a receiving part that fits into the transmitting/receiving cover holder of a handset/receiver coupler for a general-purpose telephone, and a fitting part that fits into a handset/receiver of a decorative telephone. By providing an adapter integrally formed with the parts and interposing the adapter between the handset of the decorative telephone and the coupler for the general-purpose telephone to connect the two, one type of combination for the handset and receiver can be achieved. Since the receiver can be shared with two or more types of handsets with different shapes by simply attaching and detaching the adapter, there is no need to install a dedicated transmitter/receiver cover holder or a combiner for the handset/receiver, and the practical effect is Extremely large.

Furthermore, since it is made of soft synthetic resin, it has good adhesion and extremely excellent sound insulation.
