Description

  The present invention relates to a support for a vehicle-mounted receiver for holding a vehicle-mounted receiver such as a microwave detector or an infrared detector installed in the interior of an automobile on a sun visor.

  In recent years, a large number of automatic speed control devices for controlling speed violators have been installed around roads and the like. As an example of an automatic speed control device, a microwave in a predetermined frequency band is emitted toward a vehicle, and the reflected wave is received to measure the traveling speed of the vehicle. In order to detect the presence of such an automatic speed control device, a microwave detector configured to detect a microwave emitted from the automatic speed control device and output an alarm is conventionally known.

  Moreover, the radio waves and electromagnetic waves emitted toward the automobile are not limited to the above-described microwaves, and for example, there are infrared rays for imaging a license plate. And there exists an infrared detector which incorporated the function for detecting the infrared rays in the microwave detector, or was mounted alone.

  These vehicle-mounted receivers such as microwave detectors and infrared detectors are installed at predetermined positions in the vehicle compartment via predetermined supports. As a mounting location of the support, a windshield or a dashboard is generally used, and a support suitable for each is usually prepared. Therefore, the user selects a support suitable for the installation location and installs the receiver.

In addition, there are some in-vehicle receivers that are attached to the sun visor in an inverted state. And the support tool for attaching to such a sun visor becomes a structure suitable for attaching to the sun visor which is an installation location reliably and easily. That is, a clip that is sandwiched from above and below with respect to the sun visor is provided, and the clip is connected to the in-vehicle receiver directly or via a connecting mechanism. In addition, although the patent document which disclosed the support tool for attaching this vehicle-mounted receiver to a sun visor was not found, as a tool for attaching a vehicle-mounted microphone to a sun visor, the one disclosed in Patent Document 1 is available. is there. The fixture disclosed in Patent Document 1 also employs a structure in which a clip with a microphone attached is fixed by being sandwiched between sun visors.
Japanese Patent Laid-Open No. 11-255036

  However, the above-described conventional support for a vehicle-mounted receiver compatible with a sun visor has the following problems. That is, in the case of a receiver, it is necessary to attach the built-in antenna so as to face the installation direction (traveling direction) of an electromagnetic wave transmitter such as a microwave to be detected. Therefore, it is preferable to adjust the angle of the receiver as well as the support, but the vertical angle cannot be adjusted.

  Furthermore, recent in-vehicle receivers are equipped with a GPS antenna, acquire the current position with the GPS antenna, and have a detection object in the surroundings compared with position information such as a detection object stored in advance. In some cases, an alarm is issued. This makes it possible to detect the presence of an automatic speed control device of a type that does not transmit radio waves, such as a loop coil buried in the ground. In such a vehicle-mounted receiver equipped with a GPS antenna, for the convenience of mounting the GPS antenna on the top surface, if the top and bottom are reversed to be attached to the sun visor, the GPS antenna will face down and position detection will not be possible. . Therefore, a structure has been developed in which a rotatable plate is attached to the top side of the in-vehicle receiver main body, and a GPS antenna is mounted on the surface of the plate (on the side not facing the in-vehicle receiver main body).

  In other words, this plate can be rotated by loosening the angle adjustment screw provided on the hinge portion connected to the in-vehicle receiver body, and when the angle adjustment screw is tightened, the angle at that time is maintained and fixed. It is like that. Therefore, when mounting the in-vehicle receiver on the dashboard or on the windshield, the plate should be placed so as to cover the top surface of the in-vehicle receiver main body, and when mounting on the sun visor, the plate should be rotated by a predetermined angle. Make sure that the surface of the is facing up. As a result, the GPS antenna can be directed upward regardless of the orientation of the in-vehicle receiver body, and the current position information can be detected.

  However, in actuality, the position of the sun visor differs depending on the vehicle type. Therefore, even if the plate is rotated, the ceiling surface of the vehicle is positioned above the GPS antenna, and radio waves from the satellite may not be received.

  The present invention makes it possible to hold an in-vehicle receiver mounted on a bracket at an arbitrary angle and hold it, and in the case of a type equipped with a GPS antenna, makes it easy to detect current position information regardless of the position of the sun visor. An object of the present invention is to provide a support for a vehicle-mounted receiver.

  In order to achieve the above-described object, a vehicle-mounted receiver support according to the present invention includes a clip that is sandwiched and fixed to a sun visor in a vehicle interior, a bracket that is mounted at a predetermined position of the vehicle-mounted receiver, and the clip. The clip includes a connection mechanism that connects to the bracket, and the clip is linked to the bracket so as to be rotatable with respect to the bracket and movable in the front-rear direction, and is stopped and fixed at a predetermined position. Configured to do.

  The in-vehicle receiver mounted on the bracket can be set to an arbitrary angle posture, moved to a predetermined position in the front-rear direction, and fixed in that state. Therefore, for example, in the case of a type in which a GPS antenna is mounted on an in-vehicle receiver, the current position information can be easily detected regardless of the position of the sun visor by moving the in-vehicle receiver forward and backward and setting the GPS antenna at a desired position. can do. Of course, the present invention can also be applied to a vehicle-mounted receiver without a GPS antenna.

  And more preferably, the clip has a pair of bracket connecting pieces formed with both side edges directed to the bracket side, and the bracket connecting piece has a long hole extending in the front-rear direction, The bracket has first and second bearing portions that respectively contact the pair of bracket coupling pieces, and the coupling mechanism includes a sleeve inserted into a cylindrical recess provided in the second bearing portion, and the first 1. A shaft inserted into a through-hole provided in the second bearing portion, a shaft holder for storing the head portion of the shaft in a non-rotatable manner, a screw attached to the tip of the shaft, and the sleeve and the shaft holder Toothed portions are provided on the opposing surfaces, and the both toothed portions are engaged by tightening the screw to suppress the rotation of the sleeve and the shaft holder. Further, in a state where the tip end of the shaft is inserted into the through hole of the first bearing portion, a detent mechanism for suppressing the rotation of the shaft, and the sleeve as an elongated hole of the bracket connecting piece A rotation stop mechanism that suppresses relative rotation in the inserted state is provided. Here, the bracket connecting piece provided on the clip may be formed integrally by bending both side edges of the clip to the bracket side as shown in the embodiment, or the bracket connecting piece may be formed as a separate piece without being bent. It may be provided and attached to the clip.

  Further, the clip has a pair of bracket connecting pieces formed with both side edges directed to the bracket side, the bracket connecting piece has a long hole extending in the front-rear direction, The pair of bracket connecting pieces has a bearing portion sandwiched from both sides, and the connecting mechanism includes a sleeve inserted into a cylindrical recess provided on one side surface of the bearing portion, and a through hole provided in the bearing portion. A shaft that is inserted into the shaft, a shaft holder that houses the head of the shaft in a non-rotatable manner, and a screw that is attached to the tip of the shaft, and a tooth profile is provided on each of the opposing surfaces of the sleeve and the shaft holder, By tightening, the both teeth are meshed so that the sleeve and the shaft holder are prevented from rotating. A rotation stop mechanism that suppresses rotation of the shaft in a state in which the tip of the shaft is inserted into the through hole of the bearing portion, and relative rotation is suppressed in a state in which the sleeve is inserted into the elongated hole of the bracket connecting piece. You may comprise so that a rotation stop mechanism may be provided.

  According to each invention described above, when the screw is loosened, the relative rotation between the clip and the bracket and the forward / backward movement can be performed. Then, when the screw is tightened, the two tooth portions engage with each other and the rotation of the sleeve is suppressed, so that the bracket connecting piece that rotates integrally with the sleeve, and thus the rotation of the clip is suppressed. Further, by tightening in such a manner, the distance between the screw and the shaft is shortened, a pressure is generated on the bracket connecting piece, and the movement in the front-rear direction is suppressed.

  In the present invention, the in-vehicle receiver mounted on the bracket can be held at any angle and can be held, and in the case of a type equipped with a GPS antenna, the current position information can be easily detected regardless of the position of the sun visor. be able to.

  FIG. 1 shows an exploded perspective view of a preferred embodiment of a support for an in-vehicle receiver according to the present invention, and FIG. 2 shows a use state (a state attached to the in-vehicle receiver). 3 shows a state in which the plate 54 is rotated from the state of FIG.

  As shown in the figure, in the present embodiment, a clip 10 for attaching to a sun visor in a vehicle interior, a bracket 30 for attaching the clip 10 to be rotatable and slidable, and a coupling mechanism for connecting the clip 10 and the bracket 30 to each other. 20 is provided. By operating this connecting mechanism 20, the relative positional relationship between the clip 10 and the bracket 30 can be changed or fixed in the changed state.

  The clip 10 is formed by pressing a single metal plate into a predetermined shape, and has a substantially U-shaped clip body 11. The clip main body 11 includes a flat plate portion 12 located on the bracket 30 side, a curved portion 13 continuing to the flat plate portion 12, and a holding plate portion 14 continuing to the curved portion 13. The curved portion 13 has an arc shape with a semi-circular cross section, and the flat plate portion 12 and the holding plate portion 14 face each other at a predetermined distance, and the interval between the two is the open side (the curved portion 13 and the curved portion 13). It gradually becomes narrower as it goes to the (non-connected side). And since the clip main body 11 was substantially U-shaped, it acts as a leaf spring as a whole.

  Further, the holding plate portion 14 is provided with a cut piece provided at the center thereof and a holding piece 14a that protrudes toward the flat plate portion 12 side. Thus, basically, by attaching to the sun visor from the open side of the flat plate portion 12 and the holding plate portion 14, between the predetermined portions on the open side of the flat plate portion 12 and the holding plate portion 14, and the holding pieces 14 a The clip body 11 can be fixed to the sun visor by sandwiching the sun visor from both sides at two points between the flat plate portions 12.

  Further, both side edges of the flat plate portion 12 are bent approximately 90 degrees on the side opposite to the holding plate portion 14 to form bracket connecting pieces 15 and 15 '. The bracket connecting pieces 15, 15 'are formed in an elongated rectangular shape, and further, elongated holes 15a, 15b extending in the front-rear direction (longitudinal direction) are formed in each bracket connecting piece 15, 15'. That is, one bracket connecting piece 15 is formed with a relatively narrow first elongated hole 15a, and the other bracket connecting piece 15 'is formed with a relatively wide second elongated hole 15b.

  The bracket 30 has a box-shaped main body 35 having one surface opened, and a claw piece 36 is formed at a predetermined peripheral edge on the open side of the main body. The claw piece 36 is used for fixing the bracket 30 by being hooked in a locking hole or the like provided in the in-vehicle receiver 50 when the bracket 30 is attached to a predetermined position of the in-vehicle receiver 50.

  And the 1st, 2nd bearing parts 31 and 32 are integrally formed in the both ends predetermined position of the surface of the bracket 30 (clip 10 side). The first and second bearing portions 31 and 32 are arranged to face each other and are formed so that the through holes 31a and 32a are formed on the same axis. The shaft 21 can be inserted into the through holes 31a and 32a. The shaft 21 has a head 21a that is a hexagonal bolt, and a distal end that has a rotation stopper 21b that is a parallel plane with both radial sides cut off. Furthermore, a female screw is formed at the tip of the shaft 21.

  When the clip 10 is mounted on the bracket 30, the pair of bracket connecting pieces 15, 15 ′ straddles the first and second bearing portions 31, 32 and the first and second bearing portions 31, 32. It comes in contact with the outer surface of the. And since the above-mentioned shaft 21 is inserted in the state which attached the clip 10 to the bracket 30, it will penetrate the inside of the wide 2nd long hole 15b. However, since the length of the tip of the shaft 21 is adjusted so as to be accommodated in the first bearing portion 31, it is not inserted into the first elongated hole 15a.

  The through-hole 31a formed in the first bearing portion 31 has an inner diameter that is substantially the same as the outer diameter of the shaft 21. Further, a planar shaft rotation-preventing portion 31b is formed on the inner peripheral surface of the through-hole 31a. Is formed. The rotation of the shaft 21 is suppressed by matching the shaft rotation stop portion 31b and the rotation stop portion 21b provided at the tip of the shaft 21. Then, in the state where the shaft 21 is inserted from the second bearing portion 32 side and the tip thereof is inserted into the first bearing portion 31 (the rotation stop portions 21b and 31b are aligned), the adjustment screw 25 is placed at the tip of the shaft 21. By attaching to the provided female screw, the detachment of the shaft 21 is suppressed.

  The through-hole 32a of the second bearing portion 32 has the same inner diameter as the outer diameter of the shaft 21, which is the same as the through-hole 31a of the first bearing portion 31, but is further outside the second bearing portion 32. A cylindrical recess 32b having a diameter larger than that of the through hole 32a is provided. The cylindrical recess 32b and the through hole 31a are concentric. Then, the main body 22a of the sleeve 22 is inserted into the cylindrical recess 32b.

  The sleeve 22 includes the sleeve body 22a and a flange portion 22b provided continuously at one end of the sleeve body 22a. Further, the depth of the cylindrical recess 32b is set to be substantially equal to or longer than the length of the sleeve body 22a. Since the sleeve main body 22a is mounted from the outside of the bracket connecting piece 15 'of the clip 10 (the sleeve main body 22a passes through the second elongated hole 15b), the sleeve main body 22a is stored in the cylindrical recess 32b. The bracket connecting piece 15 ′ is sandwiched between the flange portion 22 b and the second bearing portion 32.

  Further, the peripheral surface of the sleeve main body 22a is formed with a bracket rotation stop portion 22d formed of a parallel plane with both radial sides cut off. The distance between the two planes of the bracket rotation stopper 22d is set to be approximately equal to or slightly narrower than the width of the second elongated hole 15b. Thereby, in a state where the sleeve main body 22a is inserted into the second elongated hole 15b, the bracket rotation stopper 22d is latched to the second elongated hole 15b, and relative rotational movement is prevented. In other words, the bracket connecting piece 15 ′ and thus the clip 10 rotate together with the sleeve 22. As described above, the relative rotational movement of the sleeve 22 and the clip 10 is suppressed, but the relative movement in the direction in which the second long hole 15b is formed, that is, the front-rear direction is not suppressed, and is movable. Become.

  Moreover, the 1st tooth profile part 22c is formed in the outer surface of the flange part 22b. On the other hand, the head portion 21a of the shaft 21 is accommodated in a cylindrical shaft holder 23 opened at both ends. That is, the shaft holder 23 has a hexagonal column-shaped recess 23a that substantially matches the outer shape of the head 21a of the shaft 21, and further has an inner diameter that is substantially equal to the diameter of the shaft 21 at the back center of the recess 23a. A through-hole 23b having is formed. Furthermore, a second tooth profile 23c is formed on the end surface on the side where the recess 23a is formed.

  As a result, when the adjustment screw 25 is tightened, the distance between the shaft 21 and thus the head 21a and the adjustment screw 25 is reduced, and the shaft holder 23 housing the head 21a also moves in the axial direction. Thereby, the 2nd tooth profile part 23c provided in the shaft holder 23 and the 1st tooth profile part 22c provided in the flange part 22b of the sleeve 22 mesh, and are fixed.

  Next, the in-vehicle receiver 50 such as a microwave detector will be briefly described. The flat box-shaped receiver body 51 incorporates an antenna that receives a predetermined radio wave and a signal processing circuit that analyzes the radio wave received via the antenna and issues an alarm when the target radio wave is received. Yes. The antenna 52 is provided on the front side of the receiver main body 51. The receiver main body 51 has a battery box 53 on the bottom side, and the bracket 30 is attached to the battery box 53. That is, in this example, the bracket 30 also serves as the lid of the battery box 53, but the function of the lid of the battery box is not necessarily required.

  Further, a plate 54 is rotatably connected to the top surface side of the receiver main body 51. The plate 54 can be rotated by loosening the angle adjusting screw 55 with a hinge provided on the front side of the receiver main body 51, and the angle position at that time can be maintained by tightening the angle adjusting screw 55. Become. A solar panel 56 is mounted on the upper surface of the plate 54, and a GPS antenna unit 57 is built in the top end of the upper surface.

  Thus, when the in-vehicle receiver 50 is attached to the sun visor, the plate 54 is rotated and separated from the receiver main body 51 as shown in FIG. Then, the solar panel 56 faces upward, and power generation based on sunlight is performed, and the power is supplied to the signal processing circuit and the secondary battery in the battery box 53 is charged. Furthermore, the GPS antenna unit 57 is also directed upward, so that GPS data can be received and the current position can be detected. Information on the detected current position is passed to the signal processing circuit and used for alarm control and the like.

  Next, the operation of the present embodiment will be described. First, the clip 10 is attached to a predetermined position of the sun visor, and the in-vehicle receiver 50 is attached to the sun visor. Next, the adjustment screw 25 is loosened prior to actual use. As a result, the strong meshing between the first and second tooth profile portions 22c and 23c is released, enabling forward and reverse rotation about the shaft 21 as the rotation center, and in the direction in which the first and second elongated holes 15a and 15b are formed. Able to move forward and backward along.

  Therefore, the bracket 30 and the in-vehicle receiver 50 are rotated and set to desired angles. That is, the posture is set so that the antenna 52 built in the receiver main body 51 faces forward. At this time, the amount of loosening of the adjusting screw 25 is adjusted, the first tooth profile portion 22c and the second tooth profile portion 23c are lightly engaged, and rotation is possible by applying a force in a predetermined direction. The posture (rotation angle) may be maintained by meshing between the first and second tooth profile portions 22c and 23c. That is, even if the hand is released, the state of the desired rotation angle is maintained, so that the angle (the direction of the receiver main body 51) can be confirmed from a separated position with the hand released. Even when the adjustment screw 25 is finally tightened, it is not necessary to support the receiver main body 51 with another hand, and the main body can be fixed by simply tightening the screw.

  In addition to the adjustment of the angle described above, the receiver main body 51 is also aligned in the front-rear direction. That is, in the state where the adjustment screw 25 is loosened, the shaft 21 can be relatively moved forward and backward along the first and second elongated holes 15a and 15b, and thus moved to a desired position. Specifically, the GPS antenna unit 57 provided at the front end of the plate 54 is positioned at a position where GPS data can be received without being blocked by the vehicle ceiling or the like without the plate 54 hitting the front windshield. To do. Once positioned in this way, the adjustment screw 25 is tightened. Thereby, the first and second tooth profile portions 22c and 23c are firmly meshed with each other, the rotation is stopped, the angle of the receiver main body 51 is fixed, and the flange portion 22b of the sleeve 22 and the second bearing portion 32 are fixed. By moving the bracket connecting pieces 15 and 15 ′ between the alignment adjusting screw 25 and the first bearing portion 31 with a predetermined pressing force and pinching them firmly, the movement in the front-rear direction can be stopped and fixed.

  In the above-described embodiment, the bracket 30 is provided separately as the first and second bearing portions 31 and 32. However, the present invention is not limited to this, and one bearing is provided as shown in FIG. A configuration in which the portion 37 is provided may be employed. In this case, the bearing portion 37 may be regarded as an integration of the first and second bearing portions 31 and 32.

  Specifically, as the coupling mechanism 20, a sleeve 22 inserted into a cylindrical recess 32 b provided on one side surface of the bearing portion 37, a shaft 21 inserted into a through hole provided in the bearing portion 37, and the shaft 21 A shaft holder 23 for storing the head 21a of the shaft 21 in a non-rotatable manner and an adjustment screw 34 attached to the tip of the shaft 21, and tooth profile portions 22c and 23c are provided on opposing surfaces of the sleeve 22 and the shaft holder 23, respectively. By tightening, the both teeth portions 22c and 23c are engaged to prevent the sleeve 22 and the shaft holder 23 from rotating. Further, in a state where the tip of the shaft 21 is inserted into the through hole of the bearing portion, the rotation of the shaft 21 is stopped, and relative rotation is performed while the sleeve 22 is inserted into the elongated hole of the bracket connecting piece 15. Configured to deter.
