Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a handset fixing device suitable for use in vehicle-mounted equipment such as car telephones and car facsimiles.

2. Description of the Related Art In conventional car telephones, in order to prevent the handset from coming off the handset stand due to vibrations, etc., an engaging rod is movably provided on the handset stand so that its tip protrudes from the handset stand. The rod was configured to be locked by engaging with an engagement hole formed in the receiver (see, for example, Japanese Utility Model Application Publication No. 117141/1983).

Furthermore, it has been proposed that both the handset stand and the handset are provided with a locking mechanism to prevent them from being removed (for example, Japanese Patent Application Laid-Open No. 60-103757, Japanese Utility Model Application No. 63-100886). (see publication).

However, in all of these conventional configurations, the handset stand has a special shape with a built-in mechanism for locking the handset, and it is expensive because it is attached to vehicle-mounted equipment. There was the problem of becoming something.

In addition, there has recently been a proposal to install a facsimile machine in a vehicle, but in order to prevent the handset from falling off, it would be necessary to change the handset stand to a special shape by applying the above-mentioned conventional technology. This poses a problem in that it is a product exclusively for use in vehicles and is extremely expensive.

The present invention was made in view of the above-mentioned problems, and uses a handset stand with a simple structure similar to a normal stationary handset stand used on a desk, etc., and has a single part. It is an object of the present invention to provide a handset fixing device which can be used to be mounted on a vehicle, and which can fix a handset by attaching the device.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a case, a lock pawl that is slidably held in the case and that can fit into a hook groove formed on the receiver, and A fixing device equipped with a spring that biases the lock claw in a direction to press the hooking groove is placed close to at least one of the recesses of the handset stand, which has recesses on which the receiving and speaking ports of the handset are placed, respectively. It has a structure that allows it to be detachably attached using screws or the like.

According to the above-described structure, when the fixing device is attached to the handset stand, the lock claw held in the case is fitted into the hooking groove of the handset by the spring, and the handset can be fixed. Can be used as In addition, the fixing device is not made into the body structure, so if the device is to be placed on a desk or the like, you can use only the handset holder without attaching the fixing device. . In this case, by not attaching a fixture, no extra parts are required, and the ambience is not spoiled.

As described above, in the present invention, the handset stand can be used both for normal stationary use and for vehicle mounting, and therefore, the handset stand can be used in common, reducing costs and increasing the degree of freedom in design.

Embodiment FIG. 1 is a schematic perspective view showing a handset fixing device according to an embodiment in which the present invention is applied to an automobile facsimile machine, and FIG. 2 is a partially sectional side view showing a state in which the handset is placed on a handset stand in this embodiment. be.

In FIGS. 1 and 2, 1 is a facsimile machine, 2 is a receiver, and the facsimile 1 has a receiver stand 3 formed on its upper end. This handset stand 3 has a recess 3a on which the receiving port 2a of the handset 2 is placed, and a speaking port 2b of the handset 2.
It is provided with a recess 3b for placing the holder, and a smooth surface 3c between the recesses 3a and 3b. The depths of the recesses 3a and 3b are such that, when the handset 2 is placed on the handset stand 3, an appropriate space is created between the grip part 2C and the surface 3C of the handset 2, which is necessary for attaching a fixing device 5, which will be described later. It is defined as follows. The handset 2 has a hook groove 4 on the inner side surface of the receiver 2a.

A fixture 5 is detachably attached near the recess 3a of the handset stand 3 so as to face the hooking groove 4 of the handset 2. FIG. 3 shows a horizontal cross section of this fixture 5. As shown in FIGS. 2 and 3, the fixture 5 includes a case 7 that is separably attached to the upper surface of the surface 3c with screws 6, and is slidably held in the case 7 and placed on the receiver stand 3. A lock pawl 8 that can fit into the hook groove 4 of the handset 2 placed on the phone, a spring 9 that biases the lock pawl 8 in the direction (in the direction of the arrow) that presses the lock pawl 8 against the hook groove 4, and a spring 9 that allows the lock pawl 8 to be removed. It has a preventive E-ring 10, etc. The lock claw 8 has vertically tapered surfaces 8a and 8b formed at its tip. Further, a thick portion 3d is formed on the lower surface of the receiver stand 3 to which the fixture 5 is attached, and is reinforced when the fixture 5 is fixed with the screw 6.

The operation of the handset fixing device having the above configuration will be explained below. When the handset 2 is placed on the handset stand 3, the locking claw 8 of the fixture 5 is pushed in the direction of the arrow by the spring 9, and the opening claw 8 fits into the hooking groove 4 of the handset 2, and The receiver 2a of the receiver 2 is sandwiched between the side wall of the recess 3a. As a result, the handset 2 is fixed on the handset stand 3, and even if the facsimile machine is mounted in a car and used, the handset 2 will not come off.

When taking off the handset 2, it is sufficient to simply lift the handset 2 upward. When the handset 2 is lifted upward, the tapered surface 8b at the tip of the lock pawl 8 pushes the lock pawl 8 back in the direction opposite to the arrow A, and the lock is released. Also, when setting the receiver 2, this is the reverse.

Although the case where this facsimile 1 is used as an automobile has been described above, the facsimile 1 can be used not only in this case but also as a normal stationary device. In that case, there is no need to attach the fixture 5, and therefore the fixture 5 is not attached. Further, in this case, since there is no need to form a hole penetrating the thick portion 3d, it is preferable to leave it blind or to prevent dirt, debris, etc. from entering from the outside. In the case of stationary use, since the fixture 5 is not attached, the upper surface of the handset stand 3 has a neat shape, which is also aesthetically pleasing.

In this way, this facsimile 1 can be used as a normal stationary facsimile when the fixture 5 is not attached.
By attaching the fixture 5, it can be used as a facsimile machine mounted on a car. In other words, the handset stand 3 can be used for both stationary use and car mounted use, and production costs can be reduced. Furthermore, the shape of the handset stand 3 has a great degree of freedom in terms of design, since it is only necessary to secure a place for attaching the fixture 5.

In the above embodiment, the fixed pin 5 is connected to the receiving port 2 of the handset 2.
Although an example has been shown in which the fixing device 5 is placed near the recess 3a on which the voice port 2b is placed, the present invention is not limited to this case. Fixtures may be provided in the vicinity of 3a and 3b, respectively. Furthermore, although the above-mentioned embodiment shows the case where the present invention is applied to a facsimile, it goes without saying that the present invention is not limited to facsimiles but may be applied only to telephones.

Effects of the Invention As is clear from the above description, the present invention provides a case for a handset stand, and a lock that is slidably held in the case and that can fit into a hook groove of a handset placed on the handset stand. By attaching a fixing device having a claw and a spring that biases the locking claw in a direction to press the locking claw into the hooking groove, the locking claw is fitted into the hooking groove of the handset by the spring and the handset is fixed. This makes it possible to use it as a vehicle-mounted device, and since the handset holder only needs to have a shape that allows attachment of a fixing device, a simple structure similar to a normal stationary handset holder can be used. In other words, it is possible to standardize the handset stand for both stationary and vehicle-mounted applications, which has various effects such as reducing costs and increasing the degree of freedom in design. ing.
