Description

[Detailed Description of the Invention] The present invention relates to a remote control device in which a remote control box for sending is detachable.

As shown in FIG. 1, a remote control box 3 having an operation key 4 at the front and a transmitter 12 at the rear can be installed by inserting it into the insertion hole 5T of the main panel surface 2 that stands upright on the front of the device body 1. In this remote control device, when the remote control box 3 is attached and detached as shown in FIG. In this way, we have developed a technique in which the receiving window 7 is made flush with the main panel surface 2, and the remote control wave can be received regardless of the radiation angle of the remote control wave with respect to the receiving window 7 of the remote control box 3. did.

The receiver front panel 9 equipped with the receiver window I is shown in FIG.
As shown in FIG.
When the box 3 is inserted into the box 3, the box 3 is pressed and pushed back against the receiving part sliding body spring 45, and after the box 3 is inserted, the engagement lever 55 is moved around the fulcrum 55a using the force of the engagement spring 56. Remote control box 3 by rotating around the axis
is engaged and mounted by the claw portion 55b of the engagement lever 55.

To release this attachment, press the release button 8 in the direction of the arrow to release the engagement of the remote control box 3 with the claw portion 55b of the engagement lever 55, so that the receiving section sliding body spring 45 moves the receiving section sliding body 6, The remote control box 3 is moved forward to the state shown in FIG. 3.

However, as shown in FIG. 1, when the remote control box 3 is detached from the device body 1, the receiving section sliding body 6 equipped with the receiving window T and the receiving front metal 9 is placed on the main panel surface 2.
It is moving forward until it is almost on the same plane as the 0 plane.

This becomes clearer from FIGS. 4 and 9.

Therefore, in such a state, the remote control box 3
If the receiver sliding body 6 is pushed backwards with something other than that to allow it to retreat, this will lead to unfavorable results in terms of safety protection.

In other words, if an infant presses this, for example, there is a risk of injury around the insertion hole 57 of the main panel surface 2.

Moreover, as shown in FIG. 12-1 of FIG. 12, if insertion is possible when the external position of the remote control box 3 is shifted from the frame of the insertion hole 57, the remote control box 3 is inserted around the insertion hole 5γ. There is a risk of significant damage to the external appearance of 3.

The purpose of the present invention is to eliminate the above-mentioned deficiencies and provide a remote control device in which the receiver sliding body can be retracted only when the remote control box is in the correct insertion position, and cannot be retracted in other cases. be.

In order to achieve this objective, the present invention provides a guide protrusion at the rear of the remote control box, and a receiver slider is provided on the receiver slider that advances toward the main panel surface of the device body when the remote control box is attached or removed. A blocking member is provided for blocking the remote control box at that position, and the blocking of the blocking member is released by a guide protrusion provided on the box when the remote control box is inserted.

An embodiment of the present invention will be described below with reference to FIG. 1 and FIGS. 4 to 15.

Figure 1 is an external view of a device incorporating this mechanism.

When the remote control box 3 presses the operation keys 4 arranged on the front part, the signals corresponding to each button are shown in FIG.
The receiving window T attached to the receiver front panel 9 receives the signal, and the receiver main body 13 discriminates the signal and instructs the device main body 1 to perform the respective operation.

The remote control box 3, which is in the detached state in FIGS. 1, 4, and 9, is inserted through the insertion hole 5T of the main panel surface 2 that stands upright on the front of the main body 1, and the fully installed state is shown. This is shown in FIGS. 5 and 10.

FIG. 11 shows a case where the locking mechanism is at a neutral point immediately before attachment or detachment.

By the way, in the case of this mechanism, there is a remote control box 3 and a receiving section in which the receiver main body 13 is incorporated and has a receiving window I on the front surface of the part that is suppressed by the remote control box 3 and can freely slide back and forth on the receiving base 14. The sliding body 6 slides in a direction perpendicular to the main panel surface 2, and FIG. 6 shows an external view of the structure that allows this sliding.

A box sliding guide 16 is provided with guide grooves 11 on both sides of the remote control box 30 for guiding movement, and is fixed on the receiving base with box sliding guide fixing screws 19.
It has a structure in which it is joined to the guide regulating portion 16a of 1 and regulates the left and right and top and bottom directions.

When viewed from the front, this is shown in Figure 8.

Further, the receiving section sliding body 6 has an L-shaped cross-sectional shape, and a receiving section front metal 9 is fixed to the front surface of the receiving section sliding body 6. The sliding body 6 has slides provided at three places on the receiving section sliding body 6. Groove 15
3 is achieved by being restricted from left to right and up and down by the receiving section sliding guide 21.

Figure 7 shows the situation from the front.

In addition to the receiving window 7, on the front surface of the receiving section front metal 9, there is an escape hole 58 for inserting a power supply switching member 48, which will be described later, into the remote control box 3, and a hole 58 for regulating the attachment and detachment of the remote control box 3 at a fixed position. The blocking spring 5 whose cross section is shown in FIG.
Notch 5 to prevent zero force from being applied to the receiving section sliding body 6
9. Furthermore, terminal protection molds 46 are arranged on the left and right sides as escape holes for inserting power supply terminals 47 into the remote control box 3 for supplying power from the device main body 1 during installation.

Further, the drilling guide constriction part 9a and the guide constriction part 9b are located at positions that match the guide protrusion 10 arranged at the rear of the remote control box 3, and the remote control box 3 is inserted through the insertion hole 57 of the main panel surface 2. Its function is to provide guidance when inserting the .

Now, the receiving part sliding body 6 is constantly trying to move forward due to the force of the receiving part sliding body spring 45 whose one end is fixed to the receiving base hook 44 which is a part of the receiving base 14. If the remote control box 3 is inserted against this force and continues to be suppressed backward, the receiving section sliding body suppressing section 6a will come into contact with the detection bin 18.

In other words, the distance between the two, which was separated by a distance of t□ in FIG. 9, becomes O at a certain position.

If the suppression is continued further, the detection bin 18 is installed by itself and can be slid back and forth using the detection bin slider guide 27 installed on the attachment detection base 15 fixed on the reception base 14 as a guide. The bin slider 17 begins to move backward, and the connecting shaft 2 on the detection bin slider 17
゜36 is connected to the two-contact lever 34, and the two-contact lever 34
is rotated counterclockwise around the two-contact lever fulcrum 33 on the attachment detection base 15.

A 2-contact lever spring 35 is installed between the 2-contact lever spring hook 34a and the installation detection base spring hook 15a, and this force causes the detection bin slider to be in the two different states shown in FIG. 9 and FIG. 10. Although it is possible to realize two stable states, the above-mentioned counterclockwise rotation of the two-contact lever 340 attempts to transition from the stable state shown in FIG. 9 to the stable state shown in FIG. It is done after passing.

At this time, the box suppressing member 23 that presses and fixes the remote control box 3 from the top surface is connected to the conversion lever 29 and the detection bin slider 17 by the connecting shirt (2, 36) planted thereon, so that the detection bin slider 1T is rotated counterclockwise around the box suppressing member fulcrum 28, and the box lock shaft 24 enters the mounting lock hole 5 provided on the top surface of the remote control box 3, and the box suppressing rubber 25 is remote control box 3
The movement of the two-contact lever 34, which was in close contact with the top surface and rotated counterclockwise earlier, is stopped here and the force of the two-contact lever spring 35 acts on the remote control box 3 as a pressing force of the box suppressing member 23. That will happen.

As a result of the movement up to this point, the distance between the detection pin 18 and the receiving section sliding body suppressing section 6a, which once became O in FIG. 11, is again t2.
will be separated by a distance of

At this time, the box suppressing member fulcrum 28, which is the rotational fulcrum of the box pressing member 23, is on the upper cover 22, and the upper cover 22 is fixed on the four fixed columns 20 installed on the receiving base 14. It is what was done.

FIG. 6 is an external view of the fixed support 20, and FIGS. 2 and 3 show its position, upper cover 22, and box pressing member 23 in dashed lines.

The remote control box 3 that has been installed in this way is firmly fixed in the top and bottom, left and right, and front and back.
The feeling of pressing the operation button 4 is the same as that of buttons normally fixed to the main body of the device, and reliable operation without wobbling can be obtained.

Next, in order to attach and detach this, it is sufficient to press the release button 8 exposed on the main panel surface 2 backward.

In other words, the release button 8 is pressed backward by pushing the release slider 30, which can slide back and forth on the attachment detection base 15 and is normally restricted to a fixed position forward by the force of the release slider spring 31, against the spring force. When the release slider suppressing part 30a presses the conversion lever suppressing part 29a, the conversion lever 29, which has the conversion lever fulcrum 32 on the mounting detection base 15, starts to rotate clockwise and is connected. As a result, (1) the box suppressing member 23 begins to rotate clockwise about the box suppressing member fulcrum 28, contrary to the previous installation, and (2) the detection The bin slider 17 moves forward and the two-contact lever 34 begins to rotate clockwise about the two-contact lever fulcrum 33, and the detection pin 18 and the receiving part sliding body suppressing part 6a, which were separated by a distance of t2 at the time of installation, The distance between the two points decreases again and becomes O in FIG.

At this time, the box suppressing member 23 has already been released from the upper surface of the remote control box 3 due to the movement (1), so the release button 8 is pressed on the rear part of the box suppressing member 23 and the receiving unit is moved through the detection pin 18. Sliding body 6, remote control box 3
Even if the remote control box 3 is pushed forward, the upper surface of the remote control box 3 is not damaged, and there are no factors that hinder the forward movement of both, and the attachment and detachment can be carried out smoothly.

Also, from the state shown in Fig. 4 with the remote control box 3 removed and attached,
The device is configured so that if the remote control box 3 is moved to the correct position when inserting the device, the device cannot be inserted.

That is, an insertion preventing cam part 52 is provided on the right end surface of the receiving part sliding body 6 that slides back and forth. The insertion prevention portion 38a of the receiving section sliding body blocking member 38, which is applied with a clockwise force, comes into contact with the receiving section sliding body 6 and prevents the receiving section sliding body 6 from moving backward.

With respect to this insertion blocking portion 38a, the blocking portion is slidable back and forth on the receiving portion sliding body 6 using the sliding groove 2°54 of the receiving portion sliding body 6 as a guide, and is normally restricted forward by a blocking release member spring 42. Release cam portion 41 of release member 41
A are facing each other.

A release detection pin 43 is provided at the tip of the blocking release member 41.
As seen in FIG. 7, it penetrates through the terminal protection mold 46 and protrudes to the outside from the hole of the hole guide constriction part 9a provided in the receiving part front metal 9.

Here, since the drilling guide constriction part 9a and the guide constriction part 9b are in positions that match the guide protrusion 10 arranged at the rear of the remote control box 3, the process shown in FIG. 12-2 of FIG. By doing so, the outer periphery of the remote control box 3 can fit inside the insertion hole 51 of the main panel surface 2.

Since the guiding protrusion 10 causes the release detection pin 43 to slide backward, the blocking release member 41 also slides backward against the force of the blocking release member spring 42, and as a result, as shown in FIG. The cam portion 41a rotates the receiving portion slider blocking member 38 counterclockwise against the force of the blocking member spring 39, and the insertion blocking cam portion 52 is rotated counterclockwise against the force of the blocking member spring 39.
The positional relationship is such that the insertion preventing portion 38a avoids contact with the insertion preventing portion 38a, and the receiving portion sliding body can now move rearward.

If we describe the force relationship in the front-back direction here, the sum of the two receiving part sliding body springs 45 that move the receiving part sliding body 6 forward is the sum of the blocking release member spring 42 and the blocking member spring 39. It is set to a sufficiently large value.

Further, in the embodiment, the remote control box 3 is configured to prevent the remote control box 3 from detaching from the device main body 1 as well by pressing the release button 8.

That is, if the release button 8 is pressed from the state shown in FIGS. 5 and 10, the remote control box 3 is released from the box suppression member 23 through the state shown in FIG. It is also trying to fly forward due to the suppression of the front.

If this is left as is, the receiving section sliding body spring 45 will be completely separated from the remote control box 3 and the device main body 1, resulting in the state shown in FIGS. 4 and 9.

Therefore, in order to prevent the remote control box 3 from moving forward at approximately the same movement position as the position where the detection pin 18 finishes pressing the receiving part sliding body pressing part 6a, the block is moved to the position shown in FIG. a spring 50 is fixed on the receiving base 14;
A bottom cam portion 51 is provided on the bottom surface of the remote control box 3, and the two come into contact with each other to prevent movement.

The force of preventing the movement of the remote control box 3 by the blocking spring 50 is stronger than the force of the receiving part sliding body spring 45 (FIG. 5), and the customer can move the remote control box 3 from the state shown in FIG.
In order to manually detach the device main body 1, the detachment force needs to be a deterrent force that is not extremely heavy.

In addition, in order to prevent the force of this blocking spring 50 from affecting the suppressing force of the release button 8, the bottom cam portion 51 is fixed at one point in FIG. 14 when the remote control box 3 is in FIGS. 5 and 10. A straight part 51a to avoid contact with the blocking spring 50 at the position shown by the chain line, a vertical part 51b to come into contact with the solid line, and a part to facilitate entry into the bottom cam part 51 when inserting the remote control box 3. It has a slope portion 51c.

In this way, when the release button 8 is pressed to release the remote control box 3, the forward movement of the remote control box 3 can be prevented by the blocking force of the blocking spring 50 if it is a normal suppression operation. However, when the release button 8 is pressed impulsively and the detection pin 18 impulsively pushes the receiver sliding body 6 forward, the remote control box 3 releases the blocking spring 5.
In this case, as shown in the embodiment, when the release button 8 is pressed, the release slider connecting portion 30b of the release slider 30 moves backward when the release button 8 is pressed. The connecting lever 37 is connected to the connecting lever suppressing portion 3 as shown in FIG.
7a, the receiver sliding body blocking member 38 having the blocking member fulcrum 40 on the receiving base 14 is rotated counterclockwise against the force of the blocking member spring 39 until it reaches the same position as shown in FIG. At the time when the remote control box 3 is pushed forward, the ejection blocking portion 38b engages the cam portion 4 of the receiving portion sliding body 6.
9vc should be brought into contact with it to prevent it from moving forward.

Then, when the release button 8 is stopped being pressed, the release slider 30 of the release button 8 is released by the release slider spring 3.
At the same time, the receiving section sliding member blocking member 38 is rotated clockwise again by the blocking member spring 39, and the contact between the cam portion 49 and the discharge blocking portion 38b is released.

The blocking spring 50 serves to prevent the remote control box 3 from moving forward thereafter.

As described above, according to the present invention, it is possible to prevent the receiving part sliding body from moving backward after the device main body forces, etc. of the remote control box are attached and detached, and insertion is possible only in the remote control box. Furthermore, it has become possible to smoothly and effortlessly insert the device into the insertion hole.
