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 a vehicle interior on a windshield.

  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.

  By the way, when installing on the dashboard, it is necessary to fix it with double-sided tape etc. For example, if the in-vehicle receiver is replaced with another device or the installation location is changed, the double-sided tape remains or is temporarily removed Even after the tape remains, it is not preferable. Moreover, the surface of the dashboard is not always flat and may not be attached.

On the other hand, as a type attached to the windshield, there is one disclosed in Patent Document 1, for example. In the invention disclosed in this Patent Document 1, a rotating member is attached to a base portion provided with a suction cup so as to be rotatable in the vertical direction, and a mounting table for fixing to the device is provided at the tip of the rotating member, The mounting table is rotatable in the left-right direction. As a result, the apparatus can be installed in any direction. Furthermore, the vertical rotation part of the support is fixed with screws so as to sandwich the rotation fixing part of the base part, and the horizontal rotation part can be rotated and fixed by pressing of a spring. ing.

  However, the in-vehicle receiver support for mounting on the windshield described above has the following problems. In other words, the support described in Patent Document 1 requires many parts in order to allow the apparatus to be freely installed. Further, once the position of the apparatus is determined, if the fixing pressure by the vertical screw is weak, the apparatus moves downward due to the vibration of the vehicle (particularly when the apparatus is heavy), and the apparatus cannot be installed stably. Furthermore, since the left-right direction is only pressed by the spring, there is a problem that the left-right direction changes if the apparatus is touched strongly.

  An object of the present invention is to provide a support for an in-vehicle receiver that can be fixed at an arbitrary position with few parts and can maintain the position stably after determining the position of the apparatus.

  In order to achieve the above-described object, a vehicle-mounted receiver support according to the present invention includes a base portion for mounting at a predetermined position in a vehicle interior, a base portion having a support arm provided in the base portion, and a vehicle-mounted reception device. A mounting portion mounted at a predetermined position of the machine, a first connecting portion connected to a side surface of the support arm of the base portion, and a first connecting portion connected to a non-mounting surface side of the in-vehicle receiver of the mounting portion. A connecting member having two connecting portions was provided. And while providing a 1st cylindrical part in one of the opposing surfaces of a said 1st connection part and the said support arm, the 1st recessed part which can accommodate the 1st cylindrical part is provided in the other, The said 1st cylindrical part The first outer tooth portion is provided on the outer peripheral surface of the first recess portion, and the first inner tooth portion that can be matched with the first outer tooth portion is provided on the inner peripheral surface of the first recess portion. While providing a 1st through-hole and providing the 1st insertion piece which can be elastically deformed inserted in the 1st through-hole in the 1st crevice side, the 1st insertion piece is provided with the 1st projection at the tip. The first through-hole can be inserted in an elastically deformed state, the first insertion piece is inserted into the first through-hole, and the first external tooth portion and the first internal tooth portion coincide with each other. In a state in which the first connecting hole and the support arm are relatively rotatable with the first through hole as a center of rotation, When the first insertion piece is inserted into the first through hole by a predetermined distance or more, the first protrusion is locked to the peripheral edge of the other end of the first through hole, and the separation is suppressed. The first external tooth portion and the first internal tooth portion coincide with each other to prevent rotation. The base portion and the support arm may be formed by integral formation as in the embodiment, or may be formed as separate parts and connected by screwing or the like.

  And while making the internal diameter of the other end side vicinity of the said 1st through-hole wide, the said 1st external tooth part and the said 1st internal tooth part correspond in the state which the said 1st protrusion located in the widened part. When the first insertion piece is pushed further from that state, the first protrusion is inserted into the first through hole for a predetermined distance or more, and the first protrusion is engaged with the peripheral edge of the other end of the first through hole. It is better if it is configured so that it is stopped and separation is suppressed.

  In each of the above-described inventions, the second connecting portion and the mounting portion do not necessarily have to be configured to be rotatable, and may be fixed at a predetermined angular position. Of course, as shown in the embodiment, the second connecting portion side may also be rotatable. In this case, there are various mechanisms for rotating, but the following configuration is preferable.

  That is, on the premise of each invention described above, the second connecting portion and the mounting portion are rotatably connected, and the center of rotation intersects with the first connecting portion and the rotation center of the support arm, The second cylindrical part is provided on one of the opposing surfaces of the two connecting parts and the mounting part, and the second concave part capable of accommodating the second cylindrical part is provided on the other, and the outer peripheral surface of the second cylindrical part Is provided with a second external tooth portion, an inner peripheral surface of the second recess is provided with a second internal tooth portion that can be matched with the second external tooth portion, and the second tubular portion is provided with a second penetration. A hole is provided, and a second insertion piece that is elastically deformable to be inserted into the second through hole is provided on the second recess side. The second insertion piece is provided with a second protrusion at a tip, and the second 2 is inserted into the through-hole in an elastically deformed state, and the second insertion piece is inserted into the second through-hole. In a state where the second external tooth portion and the second internal tooth portion do not coincide with each other, the second connecting portion and the support arm are relatively rotatable around the second through hole as a rotation center, and the When the second insertion piece is inserted into the second through hole by a predetermined distance or more, the second protrusion is locked to the peripheral edge of the other end of the second through hole, and the detachment is suppressed. It is preferable that the outer teeth and the second inner teeth coincide with each other to prevent rotation.

  In this case as well, the inner diameter of the second through hole is increased in the vicinity of the other end side, and the second outer tooth portion and the second inner tooth portion in a state where the second protrusion is located in the widened portion. If the second insertion piece is pushed further from that state, the second protrusion is inserted into the second through hole by a predetermined distance or more, and the second protrusion is located at the other end of the second through hole. It is good to comprise so that detachment | leave may be suppressed by latching to a periphery.

Since the first and second protrusions are positioned in the first and second through holes and the corresponding external teeth and internal teeth do not coincide with each other, the first connection and the support arm can be rotated. The relative angle between the second connecting portion and the placing portion can be set to a desired angular position. And if the 1st, 2nd insertion piece is inserted more than predetermined distance in the state which hold | maintained the angular position, a corresponding external tooth part and an internal tooth part will correspond, and an angle will be fixed. At this time, the removal of the insertion piece is also suppressed. Therefore, the angular position of each part can be positioned and fixed in a desired state, and a stable posture is maintained after positioning.
Based on the above inventions, both the first external tooth portion and the first internal tooth portion or the second external tooth portion and the second internal tooth portion may be inclined at a predetermined angle.

  In the present invention, it is possible to fix the position at an arbitrary position with few parts and to maintain the position stably after the apparatus position is determined.

  FIG. 1 shows an exploded perspective view of a preferred embodiment of a vehicle receiver support according to the present invention, FIG. 2 shows a bottom view in an assembled state, and FIG. The AA sectional view is shown. 4 and 5 show the state of use (state attached to the in-vehicle receiver).

  As shown in the drawings, in the present embodiment, the mounting unit 20 attached to the in-vehicle receiver 50 such as a microwave detector, the base unit 10 installed on the windshield, and both are positioned freely. And a connecting member 30 capable of Here, the in-vehicle receiver 50 will be briefly described. The flat box-shaped receiver main body 51 analyzes an antenna that receives a predetermined radio wave and a radio wave received via the antenna, and receives a target radio wave. It incorporates a signal processing circuit for issuing an alarm. The antenna 52 is provided on the front side of the receiver main body 51. Thereby, the microwave etc. which fly from the front can be received and notified. The on-vehicle receiver support according to the present embodiment sets the in-vehicle receiver 50 in a desired posture (for example, horizontally with the antenna 52 facing forward), and maintains the posture. It was configured as follows.

  The base portion 10 includes a base portion 11 having a substantially triangular plane and a support arm 12 that is inclined from one side edge of the upper surface of the base portion 11. The front end 12a of the support arm 12 has a shape in which one side surface is removed so that the thickness thereof is approximately halved, and the cylindrical surface of the removed one side surface 12b extends in a direction perpendicular to the side surface. A portion 13 is provided. And the through-hole 14 which penetrates the cylindrical part 13 and the front-end | tip part 12a is formed. A tapered surface 14 a is formed on the end surface of the through hole 14 on the cylindrical portion 13 side.

  Furthermore, a first external tooth portion 15 is formed on the outer peripheral surface of the cylindrical portion 13. The first external tooth portion 15 becomes an inclined surface whose diameter is gradually reduced as the distance from the side surface 12b of the tip 12a of the support arm 12 increases. And the 1st external tooth part 15 is set shorter than the cylindrical part 13, and the front end side (tooth part non-formation area | region) of the cylindrical part 13 protrudes in the front end side of the 1st external tooth part 15. FIG. It becomes like this. The base portion 11 and the support arm 12 (the cylindrical portion 13 and the first external tooth portion 15 are formed by integral formation with a synthetic resin.

  On the other hand, a hemispherical protrusion 11a is formed on the top (tip) side of the lower surface of the base portion 11, and a mounting hole 11b is formed at a predetermined position on the support arm 12 side. For example, a suction cup 45 is mounted in the mounting hole 11b. By adsorbing the suction cup 45 to the inner surface of the windshield, for example, the base portion 11 (base portion 10) can be fixed parallel to the glass surface of the windshield. In the present embodiment, the protrusion 11a is integrally formed. However, a mounting hole may be provided at the position of the protrusion 11a, and a hemispherical support aid or sucker formed of rubber or the like may be attached.

  On the other hand, the 1st connection part 31 of the connection member 30 is mounted | worn in the removed space. The connection structure between the first connecting portion 31 and the tip 12a portion of the support arm 12 is schematically shown in FIGS. That is, a concave portion 32 into which the cylindrical portion 13 can be inserted is formed on the opposite surface side of the first connecting portion 31 on the support arm 12 side, and a bifurcated portion that can be inserted into the through hole 14 at the central position of the concave portion 32. A shaped insertion piece 33 is provided. Furthermore, a protrusion 34 is formed on the outer peripheral surface on the distal end side of the insertion piece 33 so as to protrude outward.

  The insertion piece 33 is elastically deformable, and the distance W1 between the outer surfaces of the insertion piece 33 in an unloaded state is set to be equal to or smaller than the inner diameter W2 of the through hole 14, and the distance W3 between the outer surfaces of the protrusions 34 is The inner diameter W2 is set to be equal to or larger than the through hole 14 (see FIG. 6). Further, when the insertion pieces 33 are elastically deformed by applying inward (approaching direction) forces to each other, the distance W3 ′ between the outer surfaces of the protrusions 34 is set to be equal to or smaller than the inner diameter W2 of the through hole 14 ( (See FIG. 7). Furthermore, the length D1 to the protrusion 34 of the insertion piece 33 is set to be equal to or longer than the length D2 of the through hole 14. As a result, as is apparent from FIGS. 6 to 8, when the distal end of the insertion piece 33 is inserted into the through hole 14, the protrusion 34 is guided by the tapered surface 14 a serving as the guide surface of the through hole 14. Enter inside. At this time, the insertion piece 33 is elastically deformed, and the interval W3 ′ between the protrusions 34 is narrowed (see FIG. 7). When the insertion piece 33 is further pushed in that state, the protrusion 34 protrudes from the opposite side of the through hole 14. Then, as shown in FIG. 8, the inward force applied to the protrusion 34 from the inner peripheral surface of the through hole 14 is lost, so that the insertion piece 33 is elastically restored and returns to the no-load state. At this time, since the distance W3 between the outer surfaces of the protrusions 34 is equal to or larger than the inner diameter W2 of the through hole 14, the protrusions 34 are caught on the outer surface of the tip 12a of the support arm 12, and the connection member 30 and the support arm 12 are simply connected. Even if force is applied in the direction of holding and pulling them apart, separation is suppressed.

  Further, the inner peripheral surface of the concave portion 32 of the first connecting portion 31 is an inclined surface whose diameter is reduced toward the back, and the first inner tooth portion 35 that meshes with the first outer tooth portion 15 is formed on the inclined surface. The That is, the inclination angles of the inclined surfaces on which the first external tooth portion 15 and the first internal tooth portion 35 are formed are set to be equal, and the tooth pitches are also matched. Thus, as shown in FIG. 8, in a state where the insertion piece 33 is completely inserted into the through hole 14 and the first connecting portion 31 is attached to the support arm 12, the first external tooth portion 15 and the first internal tooth The part 35 is engaged and rotation is suppressed. Therefore, since the movement in the axial direction is restrained by the protrusion 34 and the movement in the rotational direction is restrained by the meshing of the first outer tooth portion 15 and the first inner tooth portion 35, the support arm 12 and the first connecting portion As a result, the relative positional relationship between the base 10 and the connecting member 30 is firmly fixed.

  Of course, for example, in a state before the insertion piece 33 shown in FIG. 4 is completely inserted, the first outer tooth portion 15 and the first inner tooth portion 35 are not engaged with each other, and therefore the first connecting portion 31 has the through hole 14. It can freely rotate in the forward and reverse directions as the center of rotation. Therefore, after rotating appropriately in such a free state and setting the relative angle between the support arm 12 and the first connecting portion 31 (connecting member 30) to an appropriate position, the insertion piece 33 is pushed into the state shown in FIG. It will be fixed at an appropriate angular position.

  The mounting portion 20 includes a flat plate-like main body 21, and both sides 21 a of the main body 21 are thinned, and a hook piece 21 b is provided at the center of the main body 21. Accordingly, by inserting both sides 21 a of the main body 21 between the integral guide rails 51 provided on the bottom surface of the in-vehicle receiver 50, separation in the direction orthogonal to the main body 21 is suppressed. Further, when the main body 21 is further translated and pushed in the inserted state, the hook piece 21b is caught by a claw piece or the like provided on the bottom surface of the in-vehicle receiver 50 (receiver main body 51), and the parallel movement is also suppressed. Thereby, the mounting part 20 can be fixed at a predetermined position of the in-vehicle receiver 50.

  A cylindrical portion 23 that extends in a direction perpendicular to the plane of the main body 21 is integrally formed at a predetermined position on the surface of the mounting portion 20 (on the side opposite to the in-vehicle receiver 50). A through hole 24 is formed in the cylindrical portion 23 along the axis true. Furthermore, a second external tooth portion 25 is formed on the outer peripheral surface of the cylindrical portion 23 on the main body 21 side. The second external tooth portion 25 also has an inclined surface whose diameter decreases as it goes to the tip.

  On the other hand, the second connecting part 36 of the connecting member 30 connected to the cylindrical part 23 and the second external tooth part 25 is a concave part 37 into which the cylindrical part 23 can be inserted on the opposite surface side on the mounting part 20 side. A bifurcated insertion piece 38 that can be inserted into the through hole 24 is provided at the center of the recess 37. Further, a protrusion 39 protruding outward is formed on the outer peripheral surface on the distal end side of the insertion piece 38. The dimensions and the like of the insertion piece 38 and the protrusion 39 are the same as those of the insertion piece 33 and the protrusion 34 provided on the support arm 12. The axial direction of the insertion piece 38 and the axial direction of the insertion piece 33 are orthogonal to each other.

  Further, the inner peripheral surface of the concave portion 37 of the second connecting portion 36 is an inclined surface whose diameter is reduced toward the back, and the second inner tooth portion 40 that meshes with the second outer tooth portion 25 is formed on the inclined surface. The That is, the inclination angles of the inclined surfaces on which the second external tooth portion 25 and the second internal tooth portion 40 are formed are set to be equal, and the tooth pitches are also matched. And the relationship between this 2nd connection part 36 and the cylindrical part 23 of the mounting part 20, and the 2nd external tooth part 25 and an effect are the above-mentioned 1st connection part 31, the cylindrical part 13, and the 1st external tooth part. 15 can be used.

  9 and 10 show a second embodiment of the present invention. In the present embodiment, the coupling mechanism of the through holes 14 (24) and the projections 34, 24 provided on the insertion pieces 33, 23 is improved. That is, the inner peripheral edge of one opening portion of the through hole 14 (24) is removed, and a step portion 14b having an enlarged inner diameter is provided. The step portion 14b is a side surface opposite to the tapered surface 14a, that is, in a connected state. And provided on the side from which the projection 34 projects. The inner diameter is wider than the inner diameter W2 of the through hole 14 and is smaller than the interval W3 when the protrusion 34 is unloaded.

  Thereby, the positional relationship between the protrusion 34 and the through hole 14 is such that the protrusion 34 is located in the through hole 14 (first state) and the protrusion 34 shown in FIG. A third state in which the protrusion 34 protrudes outward from the through hole 14 (step 14b), the protrusion 34 and the tip 12a of the support arm 12; There is a state where movement in the axial direction is suppressed. And in the 2nd state shown in FIG. 10, it sets so that the 1st external tooth part 15 and the 1st internal tooth part 35 may not mesh.

  As a result, when the transition from the first state to the second state occurs, the protrusion 34 coincides with the stepped portion 14b, so that the gap is slightly widened and the second state is shifted due to the click feeling when the protrusion 34 is expanded. Can do things. And in this 2nd state, although rotation is still free, returning to a 1st state is controlled by the engagement of the step part 14b and the protrusion 34. FIG. Accordingly, the angle is adjusted in the second state, and then the insertion piece 33 is further pushed into the third state, whereby the first outer tooth portion 15 and the first inner tooth portion 35 are engaged to rotate and rotate. Suppresses movement in the axial direction.

  As described above, since the rotation angle is adjusted in the second state, the insertion piece 33 is not accidentally moved in the axial direction during the adjustment and cannot be removed from the through hole 14. By rotating while slightly biasing in the direction of pulling out, the insertion piece 33 is accidentally pushed into the third state in which the protrusion 34 protrudes from the through hole 14, and the angle may be fixed at an unexpected position. Disappear.

  9 and 10 show the connection structure between the first connecting portion 31 and the support arm 12, the same configuration can be provided on the second connecting portion 36 and the mounting portion 20 side. Of course, a configuration related to only one of them may be applied.
