Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover for covering a predetermined portion of an apparatus, and more particularly to a cover which is opened when the predetermined portion is used.

[0002]

2. Description of the Related Art Various devices such as electric devices have a cover provided on a predetermined portion such as an operation portion such as a switch or a connector. The purpose of the cover in that case is to close the switch when not in use and disable the switch and the like, and to open and use the switch and the like when in use.

For example, in a connection panel, a connector is provided with a cover. The purpose of this cover is to prevent dust and the like from entering the connector when no microphone or the like is connected to the connector.

In a broadcasting microphone device, a cover is provided for an emergency switch for emergency / emergency broadcasting. This cover is intended to prevent the emergency switch from being erroneously operated in a normal broadcast state.

Here, in the structure provided with the cover, if the cover is easily opened when not in use, it is not preferable because the dustproof purpose is not achieved or an erroneous operation is caused.
In addition, it is not preferable that the cover be easily closed at the time of use because operation is hindered. Therefore, when the cover is closed, the cover does not shift to the open state until a force equal to or more than a predetermined value is applied.When the cover is open, the cover does not shift to the closed state until a force equal to or more than a predetermined value is applied. Must be retained.

[0006]

As a conventional technique for realizing the above-mentioned functions, for example, a cover is supported by a bearing provided on a base of the apparatus, and has a closed position parallel to the base. It is rotatable between an open position upright on the base. As a regulating structure for regulating the rotation of the cover main body, a shaft portion of the cover main body has a quadrangular cross section, and a leaf spring contacting a surface portion of the shaft portion is provided extending upward from the base. That is, when the cover body is rotated between the open position and the closed position, the corners of the shaft portion of the cover elastically deform the leaf spring, and the reaction force from the leaf spring at this time causes the rotation of the cover. Resistance to
In this way, the rotation of the cover is restricted between the closed position and the open position, and the cover is unlikely to shift to an unintended state.

However, in the structure described above, it is necessary to provide an elastic member such as a leaf spring on the base surface, which increases the number of parts and complicates the structure. It is an object of the invention to simplify the structure by which the cover can be held in place.

[0008]

According to a first aspect of the present invention, there is provided a cover for covering a predetermined portion provided in an apparatus.
It has a cover body, a rotating part, and a regulating part. The rotating portion is supported by the device so that the cover body can be rotated between a closed position covering the predetermined portion and an open position enabling the predetermined portion to be used. The restricting portion contacts the part of the device when the cover body is in the closed position and restricts the rotation of the cover body to the open position. This restricts the cover body from rotating to the closed position upon contact.

In this cover, the restricting portion makes it difficult for the cover body to pivot to the open position when in the closed position and to pivot to the closed position when in the open position. In particular, in this cover, since the cover has a regulating portion for regulating its own position and posture, the number of parts is reduced and the structure is simplified.

[0010] In the cover according to the second aspect, in the first aspect, the cover main body is rotatable to a position having a different opening degree within the open position. The restricting portion restricts the rotation of the cover main body to other positions at positions having different degrees of opening.

In this device, since the rotation of the cover main body to another position is restricted at a position having a different opening degree, the opening degree of the cover main body can be changed as required. In the cover according to the third aspect, in the first or second aspect, the restricting portion restricts the rotation of the cover main body by contacting a part of the device, and allows the rotation of the cover main body by being elastically deformed. .

In this cover, the restricting portion hits a part of the apparatus and generates a resisting force against rotation. In the cover according to claim 4, in claim 3, the rotating portion is a pair of portions provided on both side portions on one end side of the cover main body. The restricting portion is provided in the middle of a pair of portions on one end side of the cover main body, and a gap is secured between the pair of portions.

In this cover, since the restricting portion is formed separately from the rotating portion, it has low rigidity and is easily bent.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (1) First Embodiment Structure FIG. 1 shows a broadcasting microphone device 1 employing a first embodiment of the present invention. Broadcast microphone device 1
Is a device for controlling the operation of the amplifier by remote control, and comprises a main body 2 and a microphone 3 extending from the main body 2. Further, the base 4 constituting the upper surface of the main body 2 is a resin plate-like portion, on which various switches and a display unit are arranged. In this embodiment, the switches and the like are membrane switches, and the upper surface of the base 4 is generally flat.

Next, the emergency switch structure 5 provided on the base 4 of the main body 2 will be described. The emergency switch structure 5 includes an emergency switch 6 as shown in FIGS.
And a switch cover 7 for covering the emergency switch 6
And a base bearing portion 8 for rotatably supporting the switch cover 7.

The emergency switch 6 is an emergency start switch used for emergency / emergency broadcasting, and is not used for normal broadcasting. The emergency switch 6 is a membrane switch formed substantially flush with the base 4 as shown in FIG. 9, and is formed between a pair of base bearings 8 (described later). In the periphery of the emergency switch 6, the inside of the main body 2 of the broadcasting microphone device 1 is isolated from the outside, so that dust and the like do not enter. As shown in FIGS. 3, 4, and 9, the emergency switch 6 extends in the left-right direction of the main body 2.

The base bearing portion 8 is a portion for rotatably supporting the switch cover 7, and is shown in FIGS.
As shown in FIG. 1, it is formed integrally with the base 4 and protrudes upward from the flat upper surface of the base 4. Base bearing 8
Are a pair of parts arranged on both sides (left and right direction in FIG. 9) of the emergency switch 6, and each part is
Along the main body 2 in the front-rear direction. Each portion of the base bearing portion 8 includes a side portion 32 and a receiving portion 33 at a rear end of the side portion 32 on the side inward of the side portion 32 (sides facing each other). In the side portion 32, the surfaces on the sides facing each other are straight surfaces in the up-down direction and the front-back direction. The receiving portion 33 is integral with the side portion 32 but is lower than the side portion 32.

A shaft support hole 34 is formed in the side portion 32 at a position corresponding to the portion where the receiving portion 33 is formed. The shaft support hole 34 is a portion where the rotation shaft 30 (described later) of the switch cover 7 is inserted and supported. The shaft support hole 34 has a portion that opens on the side facing each other, and further,
It extends in the side part 32 and penetrates the base 4. The upper portion of the opening of the shaft support hole 34 has a semicircular shape. The shaft support hole 34 can be easily formed by a configuration in which a die from both sides abuts at the opening.

The switch cover 7 is a cover that covers the emergency switch 6 and that can be opened and closed. The switch cover 7 can maintain its state at the closed position and the open position, respectively, as described later.

The switch cover 7 is disposed on the base 4 above the emergency switch 6 and between a pair of portions of the base bearing portion 8. The switch cover 7 is a rectangular plate-shaped member that extends in the left-right direction of the main body 2. The switch cover 7 is entirely integrally formed of a resin material such as an ABS resin.
1, a rotating part 12 and a regulating part 13. The cover main body 11 mainly includes a plate portion 21, a front edge cover portion 22 extending from an edge of the plate portion 21 to the base 4, and a side edge cover portion 23. The side portion of the cover main body 11, that is, the side edge cover portion 23 is close to a pair of side portions 32 of the base bearing portion 8. Also, the front edge cover portion 22
It is shorter than the side edge cover part 23, and a relatively large gap is secured between the side edge cover part 23 and the base 4. Therefore, it is easy for the operator to open the switch cover 7 by inserting a finger into the gap.

The rotating portion 12 is a pair of portions provided at a rear corner of the cover main body 11. Each rotating part 12 is a plate part 2
1 includes a protruding portion 29 extending rearward and a pivot 30 protruding outward from the protruding portion 29 in the lateral direction. The protruding portion 29 is circular as viewed from the side as shown in FIG. 8, and is disposed and supported on the receiving portion 33. Rotating shaft 3
0 is inserted into and supported by the opening of the shaft support hole 34.
Specifically, the rotating shaft 30 is kept in contact with the upper side of the opening of the shaft support hole 34.

The entire switch cover 7 including the cover main body 11 is rotatable around the rotary portion 12 by the engagement between the rotary portion 12 and the base bearing portion 8 described above. Since the rotating shaft 30 is fitted into the shaft support hole 34 and has a high degree of sealing, the dustproof property of the electric circuit inside the base 4 is maintained.

The restricting portion 13 is a portion provided on the rear side of the cover main body 11. When the entire switch cover 7 including the cover main body 11 is at the open position or the closed position, the movement is restricted by restricting its movement. It is a part for holding in position. The restricting portion 13 includes a first portion 26 extending from the cover main body 11 and a second portion 27 extending from the tip to the base 4 side.
It is composed of The first portion 26 includes the cover body 1
It is a rectangular plate-shaped portion extending in parallel from 1 and has a lateral length slightly shorter than the cover main body 11 and a front-rear length of about 1/3. The second portion 27 is a rectangular portion extending from the first portion 26, and is formed over the entire first portion 26.

In the structure described above, the cover body 11 of the switch cover 7 is disposed above the base 4 at a predetermined distance, and extends substantially parallel to the flat base 4. Therefore, the second portion 27 extends perpendicular to the base 4. In this embodiment, the distal end of the second portion 27 is in contact with the base 4, but may be disposed slightly apart.

Since the rotating portion 12 and the regulating portion 13 extend rearward independently from the cover main body 11, a notch 14 is formed between the two. The notch 14 is an elongated gap in the front-rear direction in the plan view of FIG. As a result, the rigidity of both the rotating part 12 and the regulating part 13 is reduced, and the spring property is improved. In particular, the rotating part 12
Is easy to bend in the direction in which the tip sides approach each other (the arrow A side in FIG. 6), and the operation of fitting the rotating shaft 30 into the shaft support hole 34 is facilitated. That is, the notch 14
Thereby, the assemblability of the switch cover 7 is improved. The restricting portion 13 is easily bent in the vertical direction of the switch cover 7 (the arrow B side in FIG. 8) as described later. In summary, by providing the notch 14, the bending of the restricting portion 13 and the bending of the rotating portion 12 are realized at the same time.

Opening and Closing Operation Next, the opening and closing operation of the switch cover 7 will be described with reference to FIGS. 12 to 19 are schematic diagrams used to explain the opening and closing operation.

FIG. 12 shows a closed state of the switch cover 7. In this state, the cover main body 11 is arranged in parallel at a position separated from the upper surface of the base 4 by a predetermined distance, and
3 is located on the side of the rotation shaft 30 that is away from the emergency switch 6. Note that the switch cover 7 is rotatable in the front-rear direction of the main body 2 about the rotation shaft 30, the open side in the rotation direction of the switch cover 7 is indicated by an arrow R <b> 1, and the closed side in the rotation direction of the switch cover 7 is shown. This is indicated by arrow R2.

From the closed state in FIG. 12, the switch cover 7 is turned to the R1 side. When rotated by a predetermined angle, as shown in FIG. 13, the second portion 27 of the regulating portion 13 contacts the base 4. Since the base 4 interferes with the restricting portion 13 as described above, if the force is equal to or less than a predetermined force, the switch cover 7
13 cannot be opened to the side, and when the force is stopped, the state returns to the state shown in FIG. That is, basically, the switch cover 7 maintains the closed state of FIG.

When a predetermined force or more is applied to the switch cover 7, the state shown in FIG. 13 further shifts to the state shown in FIG. In FIG. 14, the restricting portion 13 is deformed or shifted from the position indicated by the dotted line to the position indicated by the solid line by abutting on the base 4. That is, the regulating portion 13 is elastically deformed toward the outer surface of the cover main body 11 by the reaction force from the base 4. More specifically,
In the restricting portion 13, the second portion 27 is bent so that the front end portion approaches the inner surface side of the cover main body 11, and the first portion 26 is bent.
Is bent so that the front end portion warps toward the outer surface side of the cover main body 11. At this time, the tip of the second portion 27 is
Glide on the upper surface while receiving frictional resistance from When the force is further applied, the bending of the restricting portion 13 returning to the original state at the time of slightly rotating 90 degrees shown in FIG. 15 is eliminated. More specifically, the deflection reaction force (restoring force) of the regulating unit 13
Is larger than the frictional force from the base 4, the tip of the second portion 27 of the restricting portion 13 is separated from the base 4 and located on the emergency switch 6 side with respect to the rotation shaft 30. At this time, the switch cover 7 is substantially upright with respect to the base 4 as shown in FIG. Therefore, the emergency switch 6 is in an exposed state, and can be operated. When the switch cover 7 is further turned to the R1 side, the corner 28
(The boundary portion between the first portion 26 and the second portion 27) is the base 4
Abut. Since the base 4 interferes with the restricting portion 13 in this manner, the switch cover 7 cannot be rotated to the R1 side as shown in FIG.

In the open state shown in FIGS. 15 and 16, when a predetermined force or more is applied to the switch cover 7 on the R2 side, the distal end of the second portion 27 of the restricting portion 13 comes into contact with the base 4, and The restricting portion 13 is elastically deformed by the reaction force from the base 4. At this time, the tip of the second portion 27 is the base 4
Glide on the upper surface while receiving frictional resistance. When the angle reaches a certain angle, the bending of the regulating portion 13 returning to the original state is eliminated. More specifically, when the deflection reaction force (restoring force) of the regulating portion 13 becomes larger than the friction force from the base 4,
The tip of the second portion 27 of the restricting portion 13 is detached from the base 4 and is located in a direction away from the emergency switch 6 with respect to the rotating portion 30. That is, the switch cover 7 returns to the closed state shown in FIGS.

As described above, the switch cover 7 can be maintained in the open state between the states shown in FIGS. 15 and 16 until a predetermined force or more acts. In order to achieve the above-mentioned state in the present embodiment, the distance between the rotation shaft 30 and the tip of the second portion 27 and the rotation axis must be shorter than the shortest distance from the rotation shaft 30 to the base 4. 30 to the corner 2 of the regulating portion 13
8 is long, and the shortest distance from the rotation shaft 30 to the outer surface of the second portion 27 is short.

In the closed state shown in FIG.
Since the distal end of the second portion 27 of FIG. 3 is slightly separated from the base 4, it is drawn so that the regulating force for maintaining the closed state does not work until the state of FIG. However, in the closed state of FIG.
If the tip of the portion 27 is made to substantially contact the upper surface of the base 4, a regulating force acts to keep the switch cover 7 closed from a state where the opening degree of the switch cover 7 is relatively small. . That is, the angle at which the switch cover 7 can freely rotate in the closed state becomes smaller.

The operation of further opening the switch cover 7 from the open state shown in FIGS. 15 and 16 will be described. When a predetermined force or more acts on the switch cover 7 on the R1 side, as shown in FIG. 17, the corner 28 of the restricting portion 13 comes into contact with the base 4, and the restricting portion 13 changes from a dotted line to a solid line. Deform to. That is, the regulating unit 13 is
The elastic body is elastically deformed toward the inner surface side of the cover main body 11 by the reaction force from At this time, the corner 28 is locked at a predetermined position on the base 4 by the frictional force from the base 4. As the force is further applied, the corner 28 comes off the base 4 and returns to its original state. More specifically, when the elastic force of the restricting portion 13 becomes larger than the frictional force from the base 4, the corner 2
Numeral 8 slides with respect to the base 4 and is located on the emergency switch 6 side with respect to the rotating portion 30. When the switch cover 7 is further tilted toward the R1 side from the state of FIG. 18, the cover main body 11 of the switch cover 7 comes into a state of being parallel to and close to the base 4 as shown in FIG. That is, the switch cover 7 is opened by approximately 180 degrees from the initial open state, and there is no member upright above the base 4. Even if the switch cover 7 is turned to the R2 side from the state shown in FIG. 19, the corner 28 of the restricting portion 13 abuts on the base 4 and cannot be returned with a force less than a predetermined value. That is, the switch cover 7 is held in the state shown in FIG.

In this embodiment, the cover has approximately 9
As a structure for restricting the rotation between the state of opening 0 degrees and the state of opening substantially 180 degrees, a projection is provided at the tip of the first portion 26 so as to protrude on the opposite side to the second portion 27. Is also good.

As described above, when the switch cover 7 is
It is possible to rotate by 80 degrees because, unlike the conventional case, a leaf spring or the like is not arranged at the rear of the rotating portion.

Effects The opening and closing operations of the switch cover 7 described above will be described together, and the effects of the switch cover 7 will be further described.

In the following description, FIG. 15 or FIG.
18 is called a first open state, and the state in which the switch cover 7 shown in FIG. 18 or 19 approaches the base 4 is called a second open state. Further, the concept of the open state is a concept applied to each of the first open state and the second open state, and is also used in a meaning including both open states.

The switch cover 7 can be maintained in the closed state and the open state until a predetermined force is applied. Specifically, when the switch cover 7 is in the closed state, it is difficult to shift to the first open state, which is another state, and in the first open state, the switch cover 7 is in another state, such as the closed state or the second open state. It is difficult to shift to the first open state, which is another state in the second open state. This means that the operator sets the switch cover 7 to a preferable state according to the situation, and that the state is unlikely to shift to another state for reasons other than the intention of the operator. This is required in a case where it is not preferable that an erroneous operation or unintended contact is made, such as an operation unit or a connection unit of an electric device, and that the cover must be securely opened during use. In particular, it is effective for an operation unit such as a switch in which an erroneous operation is likely to occur when the cover is open.

Further, in an emergency / emergency switch,
There is a high need to ensure that each state is maintained in the open and closed states of the cover. When the switch is erroneously operated during normal use of the device and an emergency condition is set, the reliability of the device is evaluated as low.On the other hand, when the device is used in an emergency, the cover is closed and the switch can be used quickly. If it is difficult, the purpose of emergency use cannot be achieved.

The holding force for holding the switch cover 7 at each position (the resistance force acting on the switch cover 7 from the base 4) is adjusted by the molding thickness of the regulating portion 13 and the size of the notch 14. Further, the holding position and angle of the switch cover 7 are determined by the position and shape of the restricting portion 13, the distance of each part from the rotation shaft 30, the shape of the base 4, and the like.

The feature of the present invention resides in that the switch cover 7 itself has a regulating portion 13 which regulates its own rotation and elastically deforms when a force exceeding a predetermined force acts to allow the rotation. . With this structure, the following advantageous effects can be obtained.

There is no need to provide a leaf spring or the like on the base 4 side, and the number of parts is reduced. As a result, manufacturing costs are reduced. There is no need to provide a special structure on the base 4 side, and the structure is simplified. In particular, in the present embodiment, the base 4 only needs to be provided with the base bearing portion 8, and the switch cover 7
The flat surface of the base 4 can be used for regulating the rotation of the base 4. Therefore, it is not necessary to provide a structure such as a protrusion or a notch at a position where the switch cover 7 rotates on the base 4, and the degree of freedom in designing the cover is increased. Specifically, the switch structure including the cover is easily provided at an arbitrary position on the base.

Furthermore, the simplification of the structure improves the durability of each part, so that breakage and the like hardly occur. Since there is no need to provide a leaf spring, the height of the emergency switch 6 and the switch cover 7 with respect to the base 4 of the switch cover 7 can be reduced. In the past, since the leaf spring required a certain height with respect to the base, it was necessary to provide a switch or a cover at a position protruding high with respect to the base.

When there are a plurality of open positions where the cover is held as in this embodiment, the degree of opening of the cover can be adjusted in a plurality of steps. (2) Second Embodiment In the second embodiment shown in FIGS. 20 to 21, the basic structure is the same as that of the first embodiment, and therefore only different points will be described.

In the present embodiment, the corner 28 of the switch cover 7 does not come into contact with the base 4. Specifically, the distance from the rotation axis 30 to the corner 28 is
It is set so as to be shorter than the shortest distance from to the base 4.

The switch cover 7 is turned to the R1 side from the upright state as shown in FIGS. 15 and 16 of the first embodiment. Then, since there is no interference from the base 4 to the restricting portion 13, the switch cover 7 smoothly rotates and sequentially shifts to the respective states of FIGS. 20, 21, and 22. That is, the switch cover 7 cannot rotate from the state of being upright with respect to the base 4 until a predetermined force acts on the R2 side, but can smoothly rotate on the R1 side.

As described above, in the present embodiment, the "open state" of the switch cover 7 includes an upright state to a 180 degree open state as shown in FIG. Is held from the upright state to the R2 side without resistance.

In the present embodiment, the same applies to the above-described embodiment. However, since the switch cover 7 can rotate up to 180 degrees, a large force is applied to the rotating portion 12 of the switch cover 7 and the base bearing portion 8. Does not work. Therefore, the rotating portion 12 and the like are not easily damaged. (3) Other Embodiments In the above embodiment, the restricting portion 13 is configured to function as a restricting force of rotation while allowing the rotation by elastically deforming by the reaction force from the base 4. Not only the restricting portion 13 but also any portion from the rotating portion 12 including the rotating shaft 30 fitted into the shaft support hole 34 to the restricting portion 13 through the cover main body 11, or a plurality of portions are used as bases. It may be configured to be elastically deformed by the reaction force from the fourth.

In the above embodiment, the base 4 has a flat surface. However, the cover according to the present invention can be provided in a part of a device having a shape other than the flat surface. In the above embodiment, the restricting portion is configured as a protrusion from the cover main body, but the present invention is not limited to such a form.

The cover according to the present invention can be used for switches other than the emergency / emergency switch. The cover according to the present invention can also be used for a connection portion such as a connector.

The cover according to the present invention can also be used for a side wall of a device mounted on a wall or the like. In that case, the cover generates a resistance force against gravity and is held at the open position and the closed position, respectively.

[0052]

In the cover according to the present invention, since the cover has a restricting portion for restricting its own position and posture, the number of parts is reduced and the structure is simplified.
