Abstract

PURPOSE:To prevent an event such as fall-down in advance by providing a handset base whose bottom face is formed spherical having a means by which a slave set is escaped from a physical force other than the gravity at its upper face thereby escaping the external force quickly. CONSTITUTION:A slave set is provided with a receiver 2 at its upper part when being placed and with a transmitter 4 at its lower part via a shell 3, a bottom face 5 of a case 4 is formed to be coincident with the upper face of a mount base 10 and an elastic member 8 is fixed near the surface. A bottom face 11 of the placing base 10 is nearly semi-spherical and the weight of the base is selected to keep the slave set 1 in perpendicular state when the slave set 1 is mounted and a permanent magnet 13 is provided near the upper face 12. If a clothing or the like of a person passing by the telephone set touches the slave set 1 or a rod antenna 7, the placing base 10 is tilted integrally to prevent the clothing from being sticked to the slave set 1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to cordless telephone equipment that connects via radio frequencies to public telephone lines.

Conventional technology A so-called cordless telephone (1) consists of a base unit A that connects to a public line and a slave unit B that connects to the base unit via radio frequency.
In Fig. 7), a rod antenna C is installed on the handset B in order to facilitate the transmission and reception of radio frequencies.
is installed on base unit A, rod antenna C of slave unit B
stands vertically.

Problems to be Solved by the Invention If such a cordless telephone is placed on the top of a desk, the clothing of a person passing by will touch the antenna C and cause the cordless telephone B to fall and fall to the floor. There is a risk that it will cause For this reason, it is necessary to increase the bottom area of the slave device B, resulting in problems such as poor usability and design limitations.

The present invention has been made in view of these problems, and its purpose is to provide a novel cordless telephone that can prevent the handset from falling over without impairing usability.

Means for Solving the Problems In order to solve these problems, in the present invention, the bottom surface is formed into a spherical shape, and the handset is attached to the top surface so that it can be attached by a physical external force other than gravity. The mounting table is equipped with a means for setting the table.

Operation When the slave unit is placed on the mounting table, the two are integrated by the joining means, and if a force that tries to topple the slave unit is applied in this state, the spherical surface of the bottom will cause the direction of the external force to act. This will cause the external force to be lost. When the external force is no longer applied, the restoring force of gravity acts and it becomes erect.

Embodiments The present invention will now be described in detail based on illustrated embodiments.

FIG. 1 shows an embodiment of the present invention, and reference numeral 1 in the figure indicates a handset used in pair with a base unit (not shown), with a handset 2 attached to the upper part when placed. In addition, a transmitter 4 is provided in the lower part of the body 3, and the bottom surface 5 of the case 4 is formed to match the top surface of a mounting table 10, which will be described later, and a magnetic material 6 is provided near the surface. Fixed configuration. In the figure, numeral 7 indicates a rod antenna for transmitting and receiving, and 8 indicates an electric circuit board for transmitting and receiving.

10 is a mounting table used in combination with the handset 1, and the bottom surface 1
1 is formed into an almost hemispherical shape, and the slave unit 1
The weight is set to such an extent that the slave unit 1 can be maintained in a vertical position when placed on the machine, and a permanent magnet 13 is provided near the negative surface 12.

In this embodiment, when the slave unit 1 is placed on the second side of the mounting table 10, the slave unit 1 is attracted and fixed to the mounting table 0 by the action of the permanent magnet 13 (second time).

In this state, if the clothing of a person passing by touches the handset 1 or the rod antenna 7, the mounting table O will tilt as one (FIG. 3). This allows the uke to flow by deflecting the applied force and prevents clothing from getting caught. In this way, when the force stops acting, it swings due to the spherical surface of the bottom part 11 and gravity (Fig. 3), and returns to its original state (Fig. 3).
figure).

On the other hand, when making a call, by removing the handset 1 from the mounting table 10 against the magnetic attraction force with the mounting table 10,
Since the handset 1 is separated (FIG. 1), it can be used.

4 and 5 show a second embodiment of the present invention, in which reference numeral 20 indicates a lever formed in the shape of a "■7" whose upper end 20a is connected to the body of the handset 1. From the lower end 20b
is rotatably attached by a bin 21 at the lower part so as to be exposed from the bottom part 5 of the handset unit.

In this embodiment, when the handset 1 is placed on the mounting table 10, the lower end 20b of the lever 20 is pushed by the mounting table 10, causing the upper end 20a to protrude from the body 3, while the lower end 20a is retracted into the bottom surface 5. (Figure 4).

In this state, when an external force is applied to the handset 1, the mounting table 10 swings together with the handset 1 around the bottom.
This results in a loss of external force.

On the other hand, when using the handset 1, when the body 3 of the handset 1 is grasped, the upper end 20a of the lever 20 is pulled toward the body and rotates, so the lower end 20b of the lever 20 is When the child unit 1 protrudes from the bottom surface 5 (FIG. 5), the attachment between the handset 1 and the mounting table 10 is broken and they are separated.

In this example, the mounting table is configured simply as a mounting table, but the mounting table may be configured as a hemispherical case and components that realize the functions of the base unit, such as a power supply circuit and a transmitting/receiving circuit, may be housed therein. It is clear that this effect is achieved.

Further, in this embodiment, the coupling force between the mounting table 10 and the handset 1 is obtained by the magnetic force of the boss magnet, but the mounting table side may house an electromagnet that can be turned on and off with a switch, or other fixing means may be used. For example, the side surface near the bottom of the handset 1 can be removed by using a suction cup, a cloth-like fastener, so-called Velcro tape (registered trademark), or by using a clip mechanism 30 made of a spring material or the like as shown in FIG. It is clear that the same effect can be achieved even if the device is gripped by the user.

Furthermore, by composing the bottom surface of the mounting table with rubber or elastic polymer material, the frictional force between it and the desk, etc. is increased to prevent skidding and to quickly prevent rocking when restoring. It can be attenuated to

As described in detail, in the present invention, the bottom surface is formed into a spherical shape, and the top surface is provided with a mounting table having a means for removably joining the slave device by a physical external force other than gravity. In the placed state, the spherical surface of the bottom allows the device to swing as a unit, so that external forces can be quickly released and a situation such as falling can be prevented. Furthermore, since the handset itself does not need to maintain an independent state, it is possible to make the bottom part as small as possible, and the degree of freedom in design selection can be increased. Furthermore, when the mounting stand is used as a case for the parent unit, the parent unit and the slave unit are engaged by physical forces other than power, which makes it difficult for models that require the operating power of the slave unit to come from a secondary battery. In this case, it becomes possible to perform the electrical connection with the parent device more reliably, thereby improving the reliability of the device.
