Description

  The present invention relates to a device mounting table, and more particularly to a device mounting table in which a rotating body that is rotatable with respect to a receiving member is rotated to move the device to the receiving member side.

  In order to protect and fix video equipment and audio equipment, equipment mounting tables are used. A conventional device mounting table has a structure shown in FIG. 11, for example. That is, the mounting table includes two main parts, the rotating body 12 and the receiving member 11. A device 23 such as a video device or an audio device is stored in the mounting table so as to be sandwiched between the rotating body 12 and the receiving member 11. Then, by fixing the receiving member 11 to an externally fixed object using a belt or the like, the device 23 can be used in various places without the user holding the hand 23 by hand. As a practical example, there is a usage method in which the receiving member 11 is fixed to the headrest portion of the front seat of the automobile and the user of the rear seat appreciates video or music.

  In this case, the receiving member 11 and the device 23 are always subjected to vibrations and shocks. For this reason, the mounting table ensures a structure and strength that does not cause the device 23 to fall off due to erroneous opening of the rotating body 12. There is a need. In addition, when the user exchanges playback media such as an optical disk of the device 23, it is desirable that the opening operation of the rotating body 12 be as simple as possible. Such an opening operation is performed by first opening the receiving member 11 as shown in FIG. 11B. In some cases, as shown in FIG. 11C, the device 23 is removed from the mounting table or is attached to the mounting table. In this case, the rotating body 12 is opened. It will be.

  The rotating body 12 that rotates while holding the device 23 inside is supported by a bearing 38 so as to be rotatable. Here, the bearing 38 includes a bearing hole 39 and a support shaft 40 fitted in the bearing hole 39, and the support shaft 40 is attached to the receiving member 11 side. As shown in FIG. 11B, when the rotating body 12 is rotated and moved to the position of FIG. 11B, the device 23 is also rotated at the same time, whereby the optical disk can be replaced, or as shown in FIG. 11C. In addition, the device 23 can be removed from the mounting table.

  Next, the lock mechanism of the rotating body 12 of the mounting table will be described with reference to FIG. A locked portion 42 made of a hole is formed on the receiving member 11 side, and a lock claw 41 is provided on the rotating body 12 side. When the rotating body 12 is opened and locked, the lock claw 41 takes the state shown in FIG. 12A and the state shown in FIG. 12B with the entire deformation. Therefore, the lock claw 41 needs to secure not only the opening / closing operation of FIGS. 12A and 12B but also the strength to withstand the operation in a low temperature / high temperature environment. Further, when the device 23 applies an internal pressure to the rotating body 12 due to vibration or impact, it is necessary to sufficiently secure the strength of the tip of the lock claw 41 in order to withstand this load and prevent erroneous opening. However, on the other hand, if the deformation strength of the lock claw 41 is increased too much, it will become heavy when the user opens and closes and the operational feeling will be worsened.

  In order to prevent such deterioration of the operational feeling, for example, as shown in FIG. 13, it is considered that the lock lever 51 is attached to the upper end portion of the rotating body 12 via the pin 52. However, such a structure has a drawback that the strength of the portion of the rotating body 12 where the pin 52 is provided is ensured, and the structure becomes complicated due to an increase in the number of parts such as the lock lever 51 and the pin 52, thereby increasing the cost.

  Japanese Utility Model Publication No. 59-21559 discloses a case in which a pair of side plates parallel to each other are provided substantially vertically on both sides of a bottom plate, a rotating body having substantially the same shape as this case, and end portions of both side plates are overlapped. The two side plates are fixed by screwing so that both side plates are substantially orthogonal to each other, and a hemispherical projection by drawing is provided in the overlapped portion of one side plate of the case and the rotating body, and the other side plate is provided. A long hole into which the protrusion is fitted is provided so that its longitudinal direction is substantially parallel to the vertical direction. At this time, the height of the protrusion and the depth of the long hole are substantially matched, In the fixed state, the protrusion is arranged on the end of the long hole on the bottom plate side, and when the rotating body is rotated by releasing the screwing, the protrusion is moved from the end and moved. Rotate the rotating body around the protrusion And, the opening mechanism of the case where the protrusion is to get out of the slots is disclosed.

Although such a bearing structure composed of protrusions and long holes in the opening / closing mechanism is similar to the bearing structure of the rotating body in the mounting table of the device of the present application, such a bearing structure is proposed in relation to the lock claw. It is not a thing. In other words, even with the above-described configuration, it is a subject of the present application, which avoids the lock structure accompanying the deformation of the parts only by the rotation fulcrum structure, ensures the strength of the lock claw and the bearing hole, and deteriorates the operational feeling during use by the user. It is not possible to solve the problem of the present application that abolishes.

  A main invention of the present application includes a receiving member mounted on a base and a rotating body that is rotatable with respect to the receiving member, and the rotating body is rotatable with respect to the receiving member or the base. The bearing hole to be supported by is composed of a long hole, the rotating body is rotated against the weight of the equipment supported by the rotating body, the rotating body is lifted so that the lock claw is positioned on the locked part, When the rotating body is lowered by the weight of the device, the lock claw is engaged with the locked portion and locked.

  Therefore, according to the mounting table of such a device, the lock claw is provided by arranging the device in the rotating body, rotating the device to the receiving member side, and lifting the rotating body against the weight of the device. Can be locked by being engaged with the locked portion. When releasing the lock, the closed rotating body may be lifted against the weight of the device and the lock claw may be detached from the locked portion.

  Another main invention of the present application includes a receiving member mounted on a base including a speaker, and a rotating body that is rotatable with respect to the receiving member, and the rotating body is attached to the receiving member or the base. On the other hand, the bearing hole that is rotatably supported is composed of a long hole, and is supported by the rotating body and lifts the rotating body against the weight of a playback device that does not have a speaker. When the rotating body is rotated and the rotating body is lowered by the weight of the playback device, the lock claw is engaged with the locked portion and locked.

  Therefore, according to the mounting table of such a device, the reproducing device having no speaker is mounted inside the rotating body, and the rotating device is rotated and rotated toward the receiving member, so that the reproducing device is stably provided. It is mounted on the mounting table, the lock claw is engaged with the locked portion, the rotating body is locked, and the playback device is stably held at the use position. Here, since the lock claw is made to engage with the locked portion by lifting it when rotating the rotating body, there is no elastic deformation during the locking operation, and the rotation fulcrum structure is devised. Only by this, it becomes possible to avoid a lock structure accompanied by component deformation. In addition, the strength of the material and structure of the lock claw and the locked portion can be sufficiently secured, and securing the strength does not adversely affect the operational feeling during use by the user.

  The present invention will be described below with reference to embodiments shown in the drawings. 1 to 5 show the overall configuration of a mounting table for an apparatus according to an embodiment of the present invention. The mounting table includes a base 10 and a base 10 as shown in FIG. It is comprised from the receiving member 11 distribute | arranged to the upper side and back side, and the rotary body 12 attached to the front side with respect to the receiving member 11 so that rotation is possible. Such a mounting table is used, for example, as a mounting table for a playback device that uses an optical disk such as a DVD player 23 as a recording medium.

  As shown in FIGS. 2 and 4, the base 10 includes a base 15 and a front panel 16. Here, a pair of left and right small speakers 17 are arranged on the front side of the base 15 and on the back side of the front panel 16. These speakers 17 output sound to the front side through the sound emission holes 18 of the front panel 16. On the other hand, a circuit board 19 is housed in the base 15 as shown in FIG. 2, and an audio reproduction circuit is provided on the circuit board 19. A signal cable 20 for supplying an audio signal to the audio reproduction circuit of the circuit board 19 is connected to the circuit board 19. A plug 21 is connected to the tip of the signal cable 20.

  As shown in FIGS. 4 and 5, the plug 21 is inserted into a jack 24 on the outer surface of the DVD player 23 to supply an audio signal to an audio reproduction circuit on a circuit board 19 in the base 15. ing. The jack 24 faces an opening 25 formed in the side plate portion of the rotating body 12.

  A large opening 26 is formed in the rotating body 12 attached to the front surface side of the receiving member 11, and the portion of the display panel 28 on the front surface side of the DVD player 23 is passed through the opening 26. It can be seen visually. That is, the display panel 28 constitutes the video output end. In order to protect such a display panel 28, a shutter 27 is disposed at the opening 26 so as to be freely opened and closed. The shutter 27 protects the display panel 28 of the DVD player 23 when not in use, and is lowered downward when in use, so that the shutter 27 is inserted into the gap between the DVD player 23 and the receiving member 11. It has become. The shutter 27 is made of a flexible sheet-like member such as a polypropylene resin sheet.

  6 and 7 show a state when the rotating body 12 is rotated forward with respect to the receiving member 11. For example, when the optical disk 33 is replaced, the rotating body 12 is moved to the front side. Turn to. That is, when the rotating body 12 is tilted forward with respect to the receiving member 11, the cover plate 32 that covers the mounting portion of the optical disk 33 of the DVD player 23 is exposed. Therefore, as shown in FIG. 7, by opening the cover plate 32, the mounting portion of the optical disc 33 is exposed. Therefore, the optical disk 33 can be taken out, or a new optical disk 33 can be mounted on the mounting portion, and the medium is exchanged.

  Next, the rotation support structure of the rotating body 12 will be described with reference to FIGS. The rotating body 12 is provided with a bearing hole 39 formed of a long hole to be fitted with a support shaft 38 serving as a rotation fulcrum, and the bearing 38 is constituted by the bearing hole 39 and the support shaft 40 on the receiving member 11 side. ing. 9A and 9B, the elongated body 39 allows the rotating body 12 to move not only in a rotating operation but also in the vertical direction with respect to the receiving member 11. Here, in a state where the DVD player 23 is received by the support portion 37 of the rotating body 12, the rotating body 12 is moved downward due to the weight of the DVD player 23. In this state, FIG. An opening / closing operation as shown in FIG. 8B is performed.

  When the rotating body 12 is closed, the lock claw 41 of the rotating body 12 is always loaded with the internal force in the direction of the locked portion 42 on the receiving member 11 side due to the weight of the DVD player 23 held inside through the support portion 37. For this reason, it does not open unexpectedly. Then, as shown in FIG. 9B, when the user applies an upward force F1 to the rotating body 12 and gives a rotating motion, the support shaft 40 relatively moves downward in the long hole 39, like this As a result, the rotating body 12 moves upward relative to the receiving member 11. Accordingly, the lock claw 41 is detached from the locked portion 42, and the rotating body 12 starts to open. On the contrary, when the rotating body 12 is closed, as shown in FIG. 9C, the rotating body 12 moves along the inclined surface 43 provided on the distal end side of the lock claw 41, and the lock claw 41 is moved to the locked portion 42. When the position is reached, the tip of the locking claw 41 falls into the locked part 42 and is locked.

  According to such a structure, the lock claw 41 functions as a rigid body without deformation of the lock claw 41 in order to obtain a necessary stroke to be opened and closed by the long hole 39 of the rotating body 12. Therefore, the rigidity and hardness of the lock claw 41 do not adversely affect the usability of the opening / closing operation, and a sufficient strength can be obtained at the time of design.

  Next, let us consider a case where an internal force due to the weight of the DVD player 23 housed therein is applied to the surroundings due to vibration or impact during use. Such force is applied in all directions, but even when an impact is generated in the direction in which the lock claw 41 of the rotating body 12 is opened, the rotating body 12 is formed by the inner wall of the hole constituting the locked portion 42 of the receiving member 11. Never move. Further, even when receiving a force in the rotational direction in which the rotating body 12 is opened, the lock claw 41 does not adversely affect the operational feeling, and the mechanical strength can be sufficiently increased. Such points can be considered.

  On the other hand, when the user opens the rotating body 12, it can be easily opened by applying an external force that can overcome the weight of the device of the DVD player 23 supported via the support portion 37. It does not depend on environmental conditions such as high temperatures. Further, the structure of the present embodiment is realized only by devising the structure of the bearing 38 composed of the support shaft 40 and the bearing hole 39 without increasing the number of parts, and the material cost is not increased without increasing the number of parts. There is no increase. When the DVD player 23 is placed thereon, the support portion 37 applies a rotational moment in a direction in which the rotating body 12 is closed as shown in FIG.

  Such a configuration makes it possible to avoid a lock structure accompanied by deformation of the lock claw 41 only by devising the bearing 38, ensuring the strength of the lock claw 41 and the locked portion 42, and when using the user. It is possible to avoid the correlation between the operational feelings. Furthermore, it is possible to simplify the design elements without increasing the number of parts, without impairing the user-friendliness, to eliminate the occurrence of problems due to erroneous opening, and to improve the quality and reliability of the product.

  In the above embodiment, the bearing hole 39, which is a long hole of the bearing 38, is provided on the rotating body 12 side, and the support shaft 40 is provided on the receiving member 11 side. The support shaft 40 may be provided on the rotating body 12 side, and the bearing hole 39 made of a long hole may be provided on the receiving member 11 side. Further, instead of providing the support shaft 40 or the bearing hole 39 of the bearing 38 in the receiving member 11, the support shaft 40 or the bearing hole 39 of the bearing 38 may be provided in the upper end portion of the base 10.

  Next, another embodiment will be described with reference to FIG. In this embodiment, an elastic piece 46 is provided on the receiving member 11 side so as to protrude inward, and the elastic piece 46 applies a pressing force to the DVD player 23 from the back side to the rotating body 12 side. As a result, the DVD player 23 comes into contact with the contact portion 48 of the rotating body 12 and is stably held. A transparent plate 47 is attached to the front side of the rotating body 12 so that the display panel 28 of the DVD player 23 can be seen from the front.

  According to such an embodiment, it is possible to stably hold the DVD player 23 in a state of being sandwiched between the receiving member 11 and the rotating body 12, particularly through the elastic piece 46 and the contact portion 48.

  Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention. For example, the devices stored in the mounting table in the above embodiment are not necessarily limited to the DVD player, and various other devices can be stored. For example, a CD player, a portable information terminal, or the like may be placed and stored. Alternatively, a portable navigation device may be stored and held. Moreover, it is possible to arbitrarily change the design and shape of the mounting table according to the type and size of the equipment to be stored.

  In the present invention, for example, a DVD player is fixed to a headrest portion of a front seat of an automobile, and can be used as a mounting table for a device suitable for a user to view images from the rear seat.
