Description

The present invention relates to a remote control device having a lid plate swingably attached to the front surface.

This type of remote control device includes a liquid crystal display unit and various operation switches on the front surface of the main body of the remote control device. However, some of these operation switches are operated frequently and some are operated infrequently. On the other hand, exposing all the operation switches to the front of the main unit impairs the design, so there is a request to always expose only the operation switches that are used frequently and to hide the operation switches that are used less frequently. .

Therefore, a recess is formed on the front surface of the main body, and an operation switch that is rarely used is provided in the recess and the cover is used to open and close the recess. It is known that the number of switches is reduced and the cover plate is opened when operating the operation switch in the recess (for example, refer to Patent Document 1).

When operating the operation switch in the concave portion with the cover plate open, it is desirable that the cover plate be held in the open state even if the hand is not attached. Therefore, when the lid plate is attached to the main body so as to be swingable in the vertical direction, the lid plate is held in the open state by gravity when the lid plate is swung downward.

However, when the lid plate is swung upward and the recess is hidden, it is necessary to hold the lid plate in that state. Therefore, a storage hole that opens toward the front is provided in the recess, a permanent magnet is inserted into the storage hole, and a suction plate made of a magnetic material is attached to the inside of the lid plate to swing the lid plate upward. When the concave portion is hidden by the lid plate, the attraction plate is attracted by the permanent magnet due to the magnetic force of the permanent magnet, and the lid plate is held in that state.

JP, 2014-50075, A (Drawing 2, paragraph 0005)

In the above conventional configuration, the attraction plate attached to the lid plate is attracted by the permanent magnet, but as a reaction, the permanent magnet is attracted by the attraction plate. Since the attraction force to the permanent magnet acts in the direction of pulling out the permanent magnet from the storage hole, there arises a problem that the permanent magnet projects from the storage hole due to long-term use.

In view of the above problems, it is an object of the present invention to provide a remote control device in which the permanent magnet provided on the main body side is not pulled out forward.

In order to solve the above problems, a remote control device according to the present invention has a recess formed in the front surface of a main body, and includes a swingable lid plate that opens and closes the recess, and the lid plate covers the recess. The recess is configured to open by swinging the lid plate from the state.A suction plate made of a magnetic material is attached to the inner surface of the lid plate, and the lid plate is swung to close the recess. , A bottomed storage hole that opens to the front so as to face the suction plate is formed in the recess, a permanent magnet is inserted into this storage hole, and the suction plate is attracted by the magnetic force of this permanent magnet with the lid plate closed. In a remote control device in which the lid plate is held in a closed state by sucking the above, a plate-shaped portion that forms the concave portion and that surrounds the peripheral portion in which the storage hole is formed is sandwiched in the main body. A retaining member is provided at a rear position of the permanent magnet to generate an attractive force between the permanent magnet and the permanent magnet so as to prevent the permanent magnet from projecting forward from the accommodation hole.

The magnetic force between the permanent magnet and the attraction plate acts in the direction to pull the permanent magnet forward, but the magnetic force between the retaining member and the permanent magnet acts to pull the permanent magnet backward, so pull it forward. The forces are offset and the permanent magnet does not protrude from the storage hole.

A second permanent magnet can be used as the retaining member.

Alternatively, the retaining member may be a cap-shaped magnetic path member made of a magnetic material and covering the permanent magnet from behind.

As is apparent from the above description, the present invention can prevent the permanent magnets from protruding only by adding the retaining member.

Referring to FIG. 1, reference numeral 1 is an example of a remote control device according to the present invention. The state shown in the drawing shows a state in which it is attached to a vertical wall surface, and on the front surface, in addition to the liquid crystal display section 11, operation buttons that are frequently operated left and right are arranged.

As shown in this figure (a), the cover plate 3 provided in the central portion is closed. As shown in FIG. 2B, the cover plate 3 is connected to the main body of the remote controller 1 by a pair of left and right shaft portions 31 so as to be swingable in the vertical direction. The cover plate 3 is shown in FIG. When it is rocked downward and opened like this, the concave portion 2 covered by the cover plate 3 is visible.

Operation buttons that are relatively infrequently operated are arranged in the recess 2, and a seal 12 for display and makeup is attached. On the other hand, a sticker 31 with cautionary notes is attached to the inner surface of the cover plate 3.

Below the seal 31, a suction plate 32 made of a magnetic material is provided. On the other hand, a permanent magnet 13 is attached below the seal 12 of the recess 2. Therefore, when the lid plate 3 is swung upward from the state shown in (b) to the state shown in (a), the permanent magnets 13 attract the attraction plate 32 by magnetic force, and the lid plate 3 is brought into the state shown in (a). Hold on.

Referring to FIG. 2, the permanent magnet 13 is fitted into the storage hole 21 formed in the recess 2 from the front. Therefore, the permanent magnet 13 is held so as not to project from the storage hole 21 by the frictional force generated between the inner peripheral surface of the storage hole 21 and the outer peripheral surface of the permanent magnet 13, but in the present embodiment, the permanent magnet 13 is further retained. The second permanent magnet 41 is arranged behind 13.

Since an attractive force due to magnetic force is generated between the permanent magnet 13 and the second permanent magnet 41, the permanent magnet 13 is pulled rearward and does not further project from the storage hole 21.

In the structure shown in FIG. 2, the second permanent magnet 41 is arranged behind the permanent magnet 13. However, as shown in FIG. 3, a magnetic path formed by pressing a plate-shaped body made of a magnetic material into a cap shape. The member 5 may be arranged behind the permanent magnet 13. Since an attractive force is generated between the permanent magnet 13 and the magnetic path member 5, the permanent magnet 13 is pulled backward and does not project from the storage hole 21 as in the structure shown in FIG. Further, since the magnetic flux passes through the magnetic path member 5, the distance between the attraction plate 32 and the magnetic pole is shortened, and the force of attracting the attraction plate 32 is increased.

By the way, although the case where the lid plate 3 is swung in the vertical direction has been described in the above-described embodiment, the present invention can be applied to a remote control device in which the lid plate is swung in the horizontal direction. . Further, the present invention can be applied not only to a remote control device mounted on a vertical wall surface but also to a remote control device mounted on a horizontal surface.

The present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the scope of the present invention.
