Description

  The present invention relates to a device support stand, and more particularly to a device support stand for easily mounting and fixing a small electronic device such as a small television or a car navigation to a dashboard or a glove box of an automobile.

  In recent years, electronic devices such as televisions, radios, and stereos have been developed and commercialized from the home by developing portable devices that are small, light and easy to carry, in addition to conventional stationary devices. It is taken out outdoors and used so-called outdoors, for example, in automobiles, and it is now possible to watch TV and collect various information in the car.

  However, when such devices are installed in the vehicle, various devices are already installed in the vehicle, and the installation space is limited due to the narrow interior of the vehicle. On the other hand, the device is installed near the driver's seat. In order not to hinder the driver's driving, the passengers must be able to see the screen. In recent years, various types of supports have been developed that satisfy these conditions and conditions, can be easily mounted, and can freely change the angle of the display screen of the device in the horizontal and vertical directions (for example, Patent Document 1 below) 2).

  For example, the support disclosed in Patent Document 1 below has a column-shaped support column that is erected on the upper surface of the base plate and has an uneven surface on the outer peripheral surface, and an uneven surface portion that meshes with the uneven portion of the support column on the inner peripheral surface. And a pair of clamping members that can rotate in the circumferential direction, and a support member that is sandwiched between these clamping members and that can move in the front-rear direction. It has the structure which was made.

  The support member can be repositioned to a predetermined angle by connecting a support member and a clamping member with fastening bolts and loosening an adjustment knob attached to the bolt.

A similar support tool is also disclosed in Patent Document 2 below. FIG. 9 is a perspective view of the in-vehicle display device mounting tool disclosed in Patent Document 2 below.
This in-vehicle display device mounting tool (hereinafter simply referred to as mounting tool) 100 is pivoted around a single shaft via a base 101 on which a short shaft is erected and a first movable part on the shaft. A horizontal arm that is pivotally mounted, a pair of connecting plates 103 and 103 that are swingably connected to both ends in the longitudinal direction of the horizontal arm via a pair of second movable parts 102 and 102, and each connecting plate The display device suspension member 105 is configured to be swingable between the distal end portions 103 and 103 via the third movable portions 104 and 104. The horizontal arm is formed of a strip-shaped member having a shaft insertion hole at the center and a pair of bent portions that are bent in an L shape with the ends facing upward at both ends in the longitudinal direction. Each of the first to third movable parts has a free stop mechanism, and this free stop mechanism includes a wide washer, a narrow washer, a lock member, a disc spring, and the like.
According to the fixture 100, since the display device suspension member 105 is connected to the shaft of the base 101 via the first to third movable parts, when adjusting the screen angle of the display device M, the display device Adjustments in all directions can be achieved simply by holding the device M by hand and moving it vertically and horizontally.

Utility Model Registration No. 3091972 (FIG. 1, paragraphs [0020] and [0021]) Japanese Patent Laying-Open No. 2005-199845 (FIGS. 1 and 2, paragraphs [0022] to [0040])

  According to the support disclosed in Patent Document 1, the device can be fixed by adjusting to an arbitrary angle. However, since this support tool is rotatably mounted on the outer periphery of the support column on which the pair of clamping members are erected, the support member fixed to the upper end of these clamping members is tall. For this reason, when it is going to push down the apparatus attached to a support member, since a support member is tall, the downward movement is restrict | limited. Therefore, if this support is attached to a dashboard or glove box of a car, for example, the driver's vision may be hindered depending on the installation location. Also, if the adjustment knob is loosened too much during angle adjustment, the coupling between the clamping member, the support member, and the support column may be released, and the parts may be separated, which makes the assembly adjustment again troublesome.

  In addition, the fixture 100 disclosed in Patent Document 2 has the display device suspension member 105 connected to the shaft of the base 101 via the first to third movable parts, so that the display device M is positioned at a low position. Can be adjusted and fixed at any angle. However, in this fixture 100, since all loads are applied to the strip-shaped horizontal arm fixed to the shaft erected on the base 101, a strong mechanical strength is required for the shaft and the horizontal arm. For this reason, when the display device M attached to the display device suspension member 105 becomes heavy, the horizontal arm tilts in either the left or right direction or deforms when subjected to strong vibration or the like, and similarly tilts in either direction. There is a risk that. Therefore, if the mounting tool 100 is mounted in a vehicle in which large vibrations are often generated, the position of the electronic device may not be determined due to the vibration of the vehicle, which is difficult for the user to see.

  In addition, the first to third movable parts between the shaft of the base 101 and the display device suspension member 105 are constituted by movable parts consisting of a total of five free stop mechanisms, and these free stop mechanisms are respectively wide washer, Since it is composed of parts such as narrow washers, lock members, disc spring washers, lock nuts and relatively long connecting members (bolts), the number of parts is increased, resulting in higher parts costs and more assembly man-hours. It becomes difficult to increase work efficiency. Further, since these five movable parts are all independent mechanisms, the adjustment must be carried out for each mechanism, so that the adjustment of each free stop mechanism is troublesome. Further, as described above, such a free stop mechanism is easily displaced by an external force, and thus there is a possibility that stable display cannot be performed.

  In recent years, this type of support has been designed so that when mounted on a dashboard or glove box of a car, the visual field of the driver is obstructed by electronic devices fixed to the support so as not to hinder driving. There is a demand for an electronic device that can be arranged at a user's preferred position. Further, when it is mounted in a vehicle, it is required to have high earthquake resistance because it receives strong vibrations, and the position adjustment of the device is easy and the design as a decoration is also required.

That is, when the second screw B2 and the second nut N2 are loosened, the first and second connecting members 30 and 35 are separated from each other by a predetermined distance because the bottom surface of the regulation cap CP and the bottom surface of the storage chamber 34a come into contact with each other. Since it maintains in a state, rotation of 1st-2nd movable part OP1-OP4 is permitted, without disassembling the 1st, 2nd connection members 30 and 35. FIG.

  As shown in FIGS. 1 and 2, the device fixing member 60 is formed of a plate body having a predetermined area bent in a substantially L shape in a side view. Of this plate body, the portion extending in the direction perpendicular to the fourth support shafts 40 and 45 is the back plate of the electronic device as the mounted device attached to the device support stand 1 of the present embodiment. A portion extending in parallel to the support shaft 50 is a device mounting table 61 on which an electronic device is mounted. Further, a device fixing portion 62 for fixing the electronic device in a state where the electronic device is attached is provided on the back plate portion of the device support stand 60, and the device fixing portion 62 is attached to the back surface of the electronic device (not shown) so that the device is fixed. To fix. Further, the device fixing unit 62 can release the fixed state with the device by operating an operation button 63 provided on the back surface of the device mounting table 61. The back surface of the back plate portion of the device fixing member 60 is connected to the third support shaft 50 to form the fifth movable portion OP5. The configuration of the fifth movable portion OP5 will be described in detail later. The second adjusting / combining means is shown as a constituent part and will not be described here.

Next, the configuration of the second adjusting / coupling means will be described mainly with reference to FIGS.
The second adjusting / coupling means is formed at the connecting portion between the third support shaft 50 and the device fixing member 60. One end of the third support shaft 50 is provided with a connecting portion 52 whose diameter is increased to be larger than the diameter of the portion where the gear teeth are formed. As shown, a plurality (five in this embodiment) of engagement recesses 53 are formed. In addition, a peripheral wall portion 65 that is erected vertically from the back plate portion by a predetermined length so as to cover the connecting portion 52 of the third support shaft 50 is provided at substantially the center of the back surface of the back plate portion of the device fixing member 60. Is formed. The peripheral wall 65 is a substantially ring-shaped protrusion, and a hole into which the tip of the third screw B3 is inserted is formed at the center of the bottom surface of the portion surrounded by the peripheral wall 65. A third nut N3 is disposed in the hole portion. A plurality of engaging protrusions 66 that engage with a plurality of engaging recesses 53 formed in the connecting portion 52 of the third support shaft 50 are provided around the bottom surface of the region surrounded by the peripheral wall portion 65. Is provided. The third nut N3 can be fastened with a male screw carved in a portion located on the head side a predetermined distance from the tip of the third screw B3.

  Then, the connecting portion 52 at one end of the third support shaft 50 is accommodated in the peripheral wall portion 65 of the device fixing member 60 so that the engaging recess 53 of the connecting portion 52 and the engaging protrusion 66 of the device fixing member 60 are engaged. In this state, the third screw B3 with the washer W attached from the other end side of the third support shaft 50 is inserted into the screw insertion hole 51, and the third screw B3 and the third nut N3 are fastened. The three spindles 50 and the device fixing member 60 are fixed. The second adjusting / coupling means assembled in this way is engaged with the loosening of the third screw B3, while the fifth movable part OP5 is in a state in which the rotation is restricted in the assembled state as described above. Since the engagement between the recess 53 and the engagement protrusion 66 is released, the fifth movable portion OP5 is allowed to rotate by loosening the third screw B3.

  Further, one engagement auxiliary protrusion 54 is formed on the side wall surface of the connecting portion 52 of the third support shaft 50. The same number of engagement auxiliary recesses 67 as the engagement protrusions 66 are provided on the inner wall surface of the peripheral wall portion 65 of the device fixing member 60. Since the engagement assisting protrusion 54 is provided so as to be exposed to the outside in a state where the third support shaft 50 and the device fixing member 60 are connected, the position of the engagement assisting protrusion 54 is confirmed. It becomes possible to know the engagement state of the fifth movable part OP5.

  Here, the relationship between the second movable part OP2 and the fifth movable part OP5 will be described with reference to FIGS. First, the rotation directions of the second movable part OP2 and the fifth movable part OP5 are exactly the same. Since the second movable portion OP2 has its rotation angle regulated by engaging the gear teeth of the third support shaft 50 and the gear teeth of the semi-cylindrical portions 41 and 46 of the fourth support shafts 40 and 45, The restriction angle depends on the circle pitch of the gear teeth of the third support shaft 50 and the gear teeth of the semi-cylindrical portions 41 and 46 of the fourth support shafts 40 and 45. Further, how the fifth movable portion OP5 engages the plurality of engaging recesses 53 formed in the connecting portion 52 of the third support shaft 50 with the plurality of engaging protrusions 66 of the device fixing member 60. Since the rotation angle is restricted by the rotation angle, the restriction angle depends on the installation angle interval between the engagement recesses 53 or the engagement protrusions 66.

  That is, if the fifth support shaft OP5 is not operated at all and the gear teeth of the third support shaft 50 are formed at intervals of a predetermined angle α (15 ° in this embodiment) as shown in FIG. 7, for example. The installation angle of the electronic device attached to the device fixing member 60 can be adjusted only by a predetermined angle α. However, according to the device support stand 1 of the present embodiment, in addition to the rotation restriction at the second movable portion OP2, the rotation restriction can be performed at the fifth movable portion OP5. The joint recesses 53 or the engagement protrusions 66 are formed at intervals of the installation angle β (72 ° in the present embodiment), so that the installation angle of the electronic device can be adjusted at a smaller angle interval. Specifically, when the angle α is 15 ° and the angle β is 72 ° as in the present embodiment, the installation angle of the electronic device can be adjusted at intervals of 3 °. Note that the angle α and the angle β are set to be different from each other. More preferably, the angle β is set so as not to be a multiple of the angle α.

By fixing the first screw B1, the washer W having a diameter larger than the diameter of the first support shaft 10 is fixed to the end portion of the first support shaft 10 on the side where the base 11 is not provided. When the semi-cylindrical portions 21 and 26 of the shafts 20 and 25 are brought into contact with the outer peripheral surface of the first support shaft 10, the first support shaft 10 does not come out along the gear teeth.

  Next, the third support shaft 50 and the device fixing member 60 are connected to form the fifth movable portion OP5. Although this connection method has already been described above, the third screw B3 to which the washer W having a diameter larger than the diameter of the portion where the gear teeth of the third support shaft 50 are formed is formed by the connection portion 52 of the third support shaft 50. Since it is inserted and fixed from the end portion on the side that is not provided, the semi-cylindrical portions 41 and 46 of the fourth support shafts 40 and 45 are brought into contact with the outer peripheral surface of the third support shaft 50 by this washer W. In this state, the third spindle 50 does not come out along the gear teeth.

  The first and second connecting members 30 and 35 are the second support shaft restricting projections 31a and 36a and the fourth support shaft restricting projection 31b in the second support shaft connecting portions 32a and 37a and the fourth support shaft connecting portions 32b and 37b. 36b are mounted with springs S1, S1 and S2, S2, respectively, and the second support shafts 20 and 25 are cylindrical in the second support shaft connection portions 32a and 37a and the fourth support shaft connection portions 32b and 37b. The cylindrical portions 42 and 47 of the portions 22 and 27 and the fourth support shafts 40 and 45 are inserted. By this insertion, the springs S1, S1, and S2, S2 are inserted into the hollow portions in the cylindrical portions 22, 27, 42, and 47.

  Next, the cylindrical portions 22, 27 and 42, 47 of the second support shafts 20, 25 and the fourth support shafts 40, 45 are connected to the second support shaft connection portions 32a, 37a of the first and second connection members 30, 35, respectively.

And the tip of the guide protrusion 33 is accommodated in the guide protrusion support member 38 and the second screw B2 is inserted from the communication hole 39 of the second connecting member 35 in this state. It inserts toward the through-hole 34 of 33, and is fastened by the 2nd nut N2. In addition, the regulation cap CP is fixed by crimping to the distal end portion of the second screw B2 fastened to the second nut N2 located in the accommodation chamber 34a. At this time, the gap between the bottom surface of the restriction cap CP and the bottom surface of the storage chamber 34a is set to about several mm.

  By fastening the second screw B2 and the second nut N2, the semi-cylindrical portions 21 and 26 of the second support shafts 20 and 25 and the fourth support shaft 40 are formed on the outer peripheral surfaces of the first support shaft 10 and the third support shaft 50. , 45 are in contact with each other, and the second support shafts 20, 25 and the fourth support shafts 40, 45 are connected to the first support shaft 10 side and the first support shafts by springs S1, S1, S2, and S2. The first movable portion OP1 and the second movable portion OP2 are formed by the gear teeth formed on the respective members being urged toward the three support shafts 50 and meshing with each other. Similarly, the gear teeth formed at the tips of the cylindrical portions 22, 27, 42, 47 of the second support shafts 20, 25 and the fourth support shafts 40, 45, the second support shaft connecting portions 32a, 37a, and the second Gear teeth formed between the four support shaft coupling portions 32b and 37b, the second support shaft restricting projections 31a and 36a, and the fourth support shaft restricting projections 31b and 36b are engaged with each other to form the third movable portion OP3 and the fourth movable portion OP3. A movable part OP4 is formed.

  The device support stand 1 having the first to fifth movable parts OP1 to OP5 is assembled by the series of steps described above. In the device support stand 1 assembled in this way, the first movable portion OP1 restricts or prevents the rotation of the first support shaft 10 in the circumferential direction with respect to the first support shaft 10 of the second support shafts 20 and 25. The second movable part OP2 restricts or permits the rotation of the third support shaft 50 in the circumferential direction relative to the fourth support shafts 40 and 45 of the third support shaft 50, The three movable portions OP3 restrict or prevent the cylindrical portions 22 and 27 of the second support shafts 20 and 25 from rotating in the circumferential direction with respect to the second support shafts 20 and 25 of the first and second connecting members 30 and 35. The fourth movable portion OP4 is allowed in the circumferential direction of the cylindrical portions 42, 47 of the fourth support shafts 40, 45 with respect to the first and second connecting members 30, 35 of the fourth support shafts 40, 45. The fifth movable portion OP5 is coupled to the third support shaft 50 of the device fixing member 60. That third is to regulate or permit the rotation in the circumferential direction of the support shaft 50.

  Further, in the state where the second screw B2 of the device support stand 1 is fastened to the second nut N2, no gap is formed between the first and second connecting members 30, 35, so the first to fourth movable parts. The gear teeth forming OP1 to OP4 are firmly meshed with each other, and the device support stand 1 is fixed without rotating in any direction. And if the 2nd screw B2 and the 2nd nut N2 are loosened, since a predetermined gap will be formed between the 1st and 2nd connecting members 30 and 35, the 1st-4th movable parts OP1-OP4 will be formed. The meshing between the gear teeth is released, and the first to fourth movable parts OP1 to OP4 can be rotated with reference to different axes. Therefore, the direction and angle of the device fixing member 60 with respect to the base 11 can be freely changed.

  Further, the device support stand 1 having the above-described configuration has two movable portions, that is, a second movable portion OP2 and a fifth movable portion OP5 as movable portions that rotate on the same axis. The installation angle of 60 can be changed in more detail. Moreover, since all the movable parts except for the fifth movable part OP5 can be formed by gear members, when the second screw B2 is fastened and the rotation of the first to fourth movable parts OP1 to OP4 is restricted. Therefore, the fixed position is hardly displaced by an external force, and the earthquake resistance can be increased.

  Moreover, according to the said structure, since the 1st, 2nd connection members 30 and 35 are formed from the elongate member, the base 11 can also be made low-profile with respect to a dashboard, a glove box, etc. of a vehicle. In addition, an electronic device such as a car navigation system attached to the device fixing member 60 can be moved and fixed to a low position that does not interfere with the driver's view.

  Furthermore, even if the second screw B2 is excessively loosened and the screwing with the second nut N2 is released, the restriction cap CP is fixed to the tip of the second screw B2, so that the first, The second connecting members 30 and 35 are held without being disassembled. Therefore, the user can operate the second screw B2 with peace of mind, and the rotation operation at the first to fourth movable parts OP1 to OP4 can be stably performed.

  In addition, in the device support stand 1 of the present invention, the first support shaft 10 and the base 11 are integrally molded. However, instead of the base 11, other mounting members such as clips or the like are described. Therefore, it is possible to withstand use in various applications regardless of the installation location or the object to be installed.
