Description

  The present invention relates to a support device for an in-vehicle device for disposing the in-vehicle device at an arbitrary arrangement position of a vehicle, for example, a dashboard, a front window, a console box, or the like.

In-vehicle devices having a display unit, for example, navigation devices, radar detection devices, etc., a support device is installed on an arbitrary position in the vehicle, for example, a dashboard so that the display unit is arranged at a position that is easy for the user to see. To support. An example of a support device for such an in-vehicle device (particularly an electronic device) is shown in Patent Document 1.
In the on-vehicle device support device of Patent Document 1, for example, as shown in FIG. 4, an adhesive sheet body is stuck in a recess 14 a as a sheet body arrangement portion on the back surface of the pedestal portion 11, and an arbitrary position in the vehicle It arrange | positions and it is made to fix through this adhesive sheet body.

JP 2011-116207 A

However, the shape in the recess 14a in the support device for the in-vehicle device of the cited document 1 is not necessarily suitable for sticking the adhesive sheet body. As shown in FIG. 4, an opening or a rib 17 is formed in the recess 14 a as an entrance when the ball holding portion 12 is accommodated in the cover portion 15. Therefore, although the pressure sensitive adhesive sheet is firmly adhered to the region appearing as a flat surface when the pressure sensitive adhesive sheet is stuck in the recess 14a, it is not adhered at all in the opening region, but is adhered in the rib 17 region. Since the portion and the portion not so are mixed, although the rib 17 region as a whole has an adhesive force, it is inferior to the region appearing as the plane described above. Therefore, for example, since the fixing force in the opening region is low, the vicinity of the recess 14a is a portion where the adhesive sheet body is easily peeled off. As described above, since the surface to which the pressure-sensitive adhesive sheet is disposed has not been fixed in certain areas (places) in the past, as a result, the fixing force of the in-vehicle device support device on the vehicle side varies depending on the area. It was.
However, if the fixing force varies in this way, even if the adhesive sheet itself does not change its adhesiveness, the weight deviation of the installed in-vehicle equipment (displacement of weight balance), the inclination of the mounting position and the mounting direction, etc. Depending on various conditions, the pressure-sensitive adhesive sheet is easily peeled off or difficult to peel off, and it is difficult to determine how much pressure-sensitive adhesive performance is given to the pressure-sensitive adhesive sheet. In the first place, it is not preferable that a region that is difficult to peel off and a region that is easily peeled off when the pressure-sensitive adhesive sheet is attached to the sheet body placement portion are mixed.
The present invention has been made to solve the above-mentioned problems, and an object thereof is to provide a support device for an in-vehicle device provided with a sheet body arrangement portion capable of firmly sticking an adhesive sheet body. It is.

In order to achieve the above object, the means 1 includes a device mounting portion for directly or indirectly mounting a vehicle-mounted device, and the vehicle-side device support device fixed to the vehicle side via a base portion. The base portion is formed with a sheet body arrangement portion for adhering a fixing pressure sensitive adhesive sheet interposed between the vehicle side, and the sheet body arrangement portion is formed with a continuous smooth surface. The sheet body placement portion is provided with a lid member that seals at least a part of the non-adhesive region. The gist is that it is configured as one.
In such a configuration, the sheet body placement portion is configured to be substantially flush by sealing the non-adhesive region by disposing the lid member, so that the adhesive sheet body is firmly attached in the sheet body placement portion. As a result, the fixing force of the support device to the vehicle is improved.

Here, the “equipment mounting portion for directly or indirectly mounting the in-vehicle device” may be such that the in-vehicle device is directly attached to the device-side mounting portion, for example, an intermediate inclusion such as a holder. It is intended that the in-vehicle device may be mounted via the.
The “adhesive sheet body” is a member that is interposed between the two when the support device is fixed to the vehicle side, and can be used in various materials, shapes, and thicknesses. The “sheet body” is a broad term for a member having a flat appearance such as a thin plate or paper, and is a concept that may or may not be flexible. For example, it may be a wooden or metal sheet. Further, the thickness of the sheet body does not have to be constant, for example, the thickness increases at a constant rate as it goes in a predetermined direction, but it is particularly preferable to make it as constant as possible. Further, the thickness of the sheet body may be non-uniform. In other words, it is not a series of continuous surfaces, but may be uneven, but it should be as uniform as possible. The thickness of the sheet body is arbitrary, but when the sheet is accommodated in a sheet body arrangement portion surrounded by a protrusion provided at the bottom of the base portion, for example, it is necessary to have a thickness that protrudes beyond the protrusion. It is.
Examples of such pressure-sensitive adhesive sheets include gel mats and double-sided tapes, such as felt materials and sponge materials, which are made of a gel material that is sticky to the material itself. The member which has an adhesive layer on both surfaces of this, the member which has an adhesive and a tape on both surfaces of a sheet-like base material, etc. are mentioned.

The “sheet body placement portion” is formed on the outer surface portion of the base portion, and includes a good adhesion region and a poor adhesion region. Here, the “adhesion good region” is a region where the pressure-sensitive adhesive sheet is favorably adhered, and the “adhesion poor region” is a region where the adhesion is not relatively good with respect to the “adhesion good region”. Therefore, the “non-adhesive region” is a concept including a case where the adhesion is not performed at all (for example, the opening portion of the above-mentioned Patent Document 1) and a case where the adhesion is not performed as much as the “adhesive region”. is there. The “continuous smooth surface” is a surface on which the pressure-sensitive adhesive sheet body can be adhered, regardless of whether it is flat or curved, without a discontinuous portion such as a step where the pressure-sensitive adhesive sheet body is not bonded.
Here, for example, the reason why the non-adhesive region is intentionally formed where it seems to be sufficient as the good adhesion region is as follows.
For example, in a molded product such as that disclosed in Patent Document 1, in order to form the cover portion 15 above the pedestal portion 11, the moving direction for releasing the mold after the cover portion 15 is inevitably formed as a mold. It is necessary to provide. In other words, the opening formed on the back surface side of the pedestal 11 is the entrance of the ball holder 12, but on the other hand, it is also a path for the mold that is inevitably formed when the mold is pulled out. Therefore, depending on the shape of the support device, there may be a case where there is an adhesion poor region such as this opening.
Further, in the molded product, the strength may not be sufficient for reducing the weight and thickness. Therefore, the rib 17 as in Patent Document 1 must be formed in the sheet body arrangement portion, and therefore, the non-bonding is not possible. In some cases, it is necessary to have a good region. Further, the molded product may have a deformed portion (for example, a raised portion, a recessed portion or a protruding portion) on the front side of the member. That is, at first glance, portions having different thicknesses may be formed. However, in that case, the so-called “shrinkage” of the thick portion of the meat (a phenomenon in which the thick portion is recessed when the thickness of the meat is different) is likely to occur. For this reason, the back surface is molded in accordance with the shape of the front surface so that it cannot actually be “shrunk”. However, in that case, the back surface becomes an irregular shape like the shape of the front surface. Therefore, as shown in FIG. 4 of Patent Document 1, there is a case where the rib 17 is formed on the back surface portion and the height of the rib 17 is aligned with the planar height in the recess 14a to stick the adhesive sheet body. It is.

Here, the “lid member” only needs to seal a part of the poor adhesion region, but it is particularly preferable to seal the entire poor adhesion region. Further, the “lid member” may be sealed only in the poor adhesion region, or may be sealed in areas other than the poor adhesion region (that is, the good adhesion region). This is because at least a part of the region where the pressure-sensitive adhesive sheet body is difficult to adhere is hidden by sealing at least a part of the poor adhesion region. The material of the “lid member” may be the same as or different from that of the base portion. Further, the external appearance is not particularly limited as long as at least the adhesion poor region is sealed and the sheet body arrangement portion can be made substantially flush.
In addition, the phrase “consisting of substantially the same surface” as used herein means that the cover member covers the sheet body arrangement portion without any seams, and even if there are slight gaps or steps, for example, depending on the thickness of the elastic adhesive sheet body If the support device is disposed at an arbitrary position of the vehicle without any problem, it is included in the substantially flush concept.
Examples of “in-vehicle devices” include electronic devices such as navigation devices, radar detection devices, and drive recorders, and other mirrors (such as electronic devices such as radar detection devices), cup holders, etc. Can be mentioned.

The gist of the means 2 is that the lid member is connected in a substantially flush manner with the good adhesion region in the disposed state to constitute the sheet placement portion substantially flush.
By configuring in this way, in addition to the above action, at least the poor adhesion region is sealed with a lid member, and the lid portion is connected substantially flush with the good adhesion region, so that the sheet arrangement portion is substantially flush. Therefore, the pressure-sensitive adhesive sheet body is firmly attached at the sheet body arrangement portion, and the fixing force of the support device to the vehicle is improved. The definition of “constitute substantially flush” is the same as above.

The gist of the means 3 is that the sheet body placement portion is surrounded by the protrusions.
By comprising in this way, in addition to the said effect | action, the area | region which arrange | positions an adhesive sheet body will be demarcated, and it will become easy to arrange an adhesive sheet body. The pressure-sensitive adhesive sheet body has an outer shape that is at least the same size or smaller than the area surrounded by the protrusions.
Here, it is understood that the “projection body” surrounds the sheet body arrangement portion, and any shape that protrudes from the reference surface of the sheet body arrangement portion may be used, for example, a ridge shape formed in a bank shape Or surrounded by a large number of pin bodies protruding like dots. In the case of surrounding with a ridge shape, there may be a cut (not of course) that is not surrounded on the way. In the state where the pressure-sensitive adhesive sheet is disposed as described above, the pressure-sensitive adhesive sheet must be thicker than the height of the protrusion.
The gist of the means 4 is that the projecting body is arranged at a position inside the outline of the base portion.
By constructing in this way, in addition to the above-mentioned action, even if there is a protrusion when the base portion is visually observed, it produces a visual effect that it does not look as thick as the thickness including the protrusion amount of the protrusion. Become.
For example, if the protrusion is formed in a ridge shape along the outline of the base portion, the base portion is recognized as the thickness including the thickness of the protrusion. Here, the shape of the ridge is taken as an example. However, if the protrusion can be visually observed regardless of the shape of the ridge, the base portion is an element that feels that much thicker. Therefore, by arranging the protrusions at positions inside the contour line in this way, an angle region in which the protrusions are not visible increases, so that the protrusions are not visually observed, thereby producing the visual effect as described above. Become.

In the means 5, the poor adhesion region is an opening on the back surface side of the hollow case portion protruding to the front side of the base portion, and the device mounting portion is directly displaceable by a support portion accommodated in the case portion. Alternatively, the gist is to support indirectly.
This constitutes a specific case where the poor adhesion region is formed on the support device. The hollow case part protruding to the front side of the base part has a back side opening part with respect to the back side of the base part. A support part is accommodated in the case part, and the device mounting part is directly or indirectly supported by the support part so as to be displaceable. The opening on the back side serves as an entrance when the support part is accommodated in the hollow case part, but in the first place, it is necessary to release the mold after molding in the molded product as described above, The path of the mold when releasing the mold is also used as the entrance of the support part. Here, “directly or indirectly” means a case where the device mounting portion is supported by the support portion via another member. For example, it is a case where it has an arm part mentioned below.
The gist of the means 6 is that the hollow case portion is disposed on the rear side of the base portion.
By comprising in this way, in addition to the said effect | action, by arrange | positioning a hollow case part back, the back surface side opening part is also arrange | positioned in the back side in the back surface side of a base part. And since the back side opening is closed with the lid member, the adhesive sheet body is firmly adhered to the back side opening, and the fixing force of the support device to the vehicle is the back side opening. There is no drop in position.
Here, if the back-side opening at the back-side opening position that is a non-adhesive region is not covered by the lid member, the adhesive sheet body cannot be attached to the back-side opening, The fixing force of the support device is reduced only at this point. Moreover, the position of the opening on the back surface side is particularly strong when the base portion of the support device with the in-vehicle device attached to the device attachment portion is fixed to the vehicle side via the adhesive sheet body. Since it is on the rear side where it is easily applied, it is not preferable that the fixing force of the supporting device is inferior at this position. However, with the means 6 , such a problem does not occur.

The gist of the means 7 is that the lid member closes at least the non-adhesion region at a position away from the center of gravity of the in-vehicle device.
By comprising in this way, in addition to the said effect | action, there exist the following effects.
When the in-vehicle device is at a position away from the center of gravity, the support device falls in the direction of the in-vehicle device due to the weight of the in-vehicle device unless the support device is fixed. However, when the poor adhesion region is formed at a position away from the center of gravity, for example, as described above, the vehicle-mounted device is disposed in front of the base portion, and the back surface side opening (adhesion poor region) is formed. In the case where the hollow case part is disposed behind the base part, since the adhesive sheet cannot adhere to the back side opening part, the fixing force of the entire base part decreases, and the support device falls in the direction of the in-vehicle device. There is a possibility that.
However, by sealing the non-adhesive region at a position away from the center of gravity by the lid member in this way, the fixing force of the entire base portion is improved, and the support device falls down in the direction of the in-vehicle device. There is nothing. Although there are elements in the vehicle that cause the adhesive sheet to easily peel off as the vehicle travels, such as acceleration, vehicle vibration, and vehicle heat, the support device is stable because the fixing force of the entire base portion increases in this way. It will be fixed in the vehicle.

In the means 8, when the in-vehicle device is attached to the device attachment portion so that the display unit side is directed forward, the in-vehicle device is disposed in front of the base portion, and the lid member is at least of the base portion. The gist is to dispose at least a part of the non-adhesive region disposed behind the center.
This configuration shows a more specific configuration when the on-vehicle device of the means 7 is located away from the center of gravity. In-vehicle equipment is generally heavier than the support device, and the front side with the display unit is heavier in in-vehicle equipment, so that the in-vehicle equipment is placed in front of the center of the base in this way If it is attached to the part, when the adhesive-inefficient region is not able adhesive covered with adhesive sheet with a lid, in particular the support device is likely to fall down in the direction of the in-vehicle apparatus, the means 8 Such a configuration is unlikely to cause such a problem.

In the means 9, a front opening is formed in the front wall portion of the hollow case portion, and the device attachment portion is supported directly or indirectly so as to be displaceable by the support portion exposed from the front opening. The gist of this is
This is a description of a more specific configuration of the device mounting portion supported by the support portion in the support device. “Direct or indirect” has the same meaning as above.
In the means 10, the front surface of the front wall portion (hereinafter referred to as the front wall surface) is inclined backward on the upper side with respect to a plane perpendicular to the surface of the base portion formed in a plane and perpendicular to the front-rear linear direction. The gist of this is
By configuring in this way, in addition to the above action, the upper side of the front wall surface is inclined rearward. Therefore, when the device mounting portion is displaced upward while the vehicle device is mounted on the device mounting portion, the front wall surface Compared with the case where the devices are arranged vertically, the device mounting portion is less likely to interfere with the hollow case portion, and the amount of displacement of the device mounting portion upward is increased. That is, when the vehicle device is set in an arbitrary direction, it is possible to set the vehicle device in a more varied direction, particularly in the upward direction as compared with the case where the front wall surface is arranged vertically.

The gist of the means 11 is that the corner portion formed by the front wall surface of the hollow case portion and the left and right wall surfaces adjacent to the front wall surface is formed in an oblique cut shape.
By configuring in this way, in addition to the above action, the corner portion formed by the front wall surface and the left and right wall surfaces adjacent to the front wall surface is formed in an oblique cut shape, so that the vehicle device is attached to the device mounting portion. If the device mounting part is displaced to the left or right side, the device mounting part is less likely to interfere with the hollow case compared to the case where such a corner portion is not formed in an oblique cut, and the device in the left-right direction The amount of displacement of the mounting portion increases.

The gist of the means 12 is that the front surface of the rear wall portion of the hollow case portion is arranged so as to substantially coincide with the rear end position of the base portion.
By adopting such a configuration, in addition to the above-described operation, the hollow case portion is disposed at the rear position of the base portion in a state that is least wasteful in space, and a hollow case portion having the same volume is formed on the base portion. In doing so, a wide area on the base part in front of the hollow case part can be secured. With such a configuration, it is possible to design the vehicle device to be attached to the device attachment portion closer to the center of gravity of the support device, and the vehicle device can be stably supported while the support device is fixed. Here, “substantially coincidence” means that not only a perfect coincidence but also some errors may be included.

The gist of the means 13 is that the support portion is held swingably with respect to the hollow case portion side by a universal joint mechanism.
By adopting such a configuration, in addition to the above-described operation, the device mounting portion can set the vehicle device in various states in a stepless manner by the support portion that is swingably held by the universal joint mechanism.
In the means 14, the universal joint mechanism includes a ball part as the support part arranged in the hollow case part and a ball holding part provided with a concave part into which the ball part arranged in the hollow case part is fitted. The gist is that it is configured.
This is a more specific configuration of the universal joint mechanism. In this way, the universal joint mechanism is composed of a ball holding portion having a concave portion in which the ball portion and the ball portion are fitted, so that the surface of the ball portion is attached to the concave portion, and the ball portion is firmly attached to the ball holding portion. It will be fitted (held). It is preferable that at least one of the ball part and the ball holding part is made of an elastic material, for example, a rubber material, an elastic plastic, an elastomer, or the like in order to improve the holding ability. When at least one of the ball portion and the ball holding portion is formed of an elastic material, it is preferable that the diameter of the concave portion is slightly smaller than the diameter of the ball portion in order to improve adhesion.

The gist of the means 15 is that the shape of the front edge portion of the concave portion of the ball holding portion and the front edge portion of the front opening is circular and the centers thereof coincide.
With this configuration, in addition to the above action, the distance from the center of the front edge of the recess and the front edge of the front opening is constant in any direction. Even if a certain part of the device mounting part (for example, an arm part described later) interferes with the front edge part, the swingable range of the support part is equal to 360 degrees in any direction. The swinging amount is not different.
The front edge of the recess and the front edge of the front opening are at least the front side of the hollow case portion where the front edge of the recess on the ball holding portion side accommodated in the hollow case portion has a small diameter and is arranged outside. The opening is preferably larger in diameter. Although the hollow case portion has a thickness, the opening on the front side formed in the hollow case portion so as to increase the swingable range of the support portion as much as possible has a larger diameter toward the outside (in front) in the thickness direction (that is, The outer side is preferably widened). The same applies to the ball holding portion. In that case, because the diameter of the inner peripheral position of the front opening of the hollow case portion is the same as the outermost (front) diameter of the front edge of the recess, the front edge is smoothly connected. Good.
The gist of the means 16 is that the front edge portion of the concave portion of the ball holding portion and the front edge portion of the front side opening portion are inclined rearward at substantially the same angle with respect to the vertical direction. To do.
By setting it as such a structure, the inclination angle of two front edge parts substantially corresponds, and a different member will be connected smoothly. In particular, when the front edge portion is configured to have a larger diameter toward the outside (front) in the thickness direction, smooth connection is difficult if the angles are different. Here, “substantially the same” means that there may be an error that may be interpreted as the same but not the same.

The gist of the means 17 is that the ball holding portion is formed with a communication hole that communicates the outside with the concave portion side.
By adopting such a configuration, in addition to the above-described action, the air pressure when the air remaining in the recess without being released when the ball portion is fitted in the recess is compressed is the communication hole. Can escape to the outside. If this communication hole is not provided, there is no escape space for the pressure of the compressed air, and in some cases, there is a possibility that a problem that the fitted ball portion is pushed out from the recess is generated.
When forming the communication hole, since the ball part is generally a molded product by a mold, the communication hole is also preferably formed by a mold, and in that case, along the mold release direction when releasing the mold. Thus, the communication hole is preferably formed.

In the means 18, the arm portion is formed forward from the support portion so that the axis passes through the swing center position of the support portion, and the device mounting portion is provided at the front end of the arm portion. The gist.
By providing the device mounting portion via such an arm portion, it is possible to take a distance from the support portion, and the vehicle-mounted device attached to the device mounting portion is made to swing the support portion (ball portion). At this time, it is possible to make it difficult to interfere with the hollow case portion. The longer the arm part is, the more difficult it is for the in-vehicle device to interfere with the hollow case part, but the in-vehicle device is supported in the form of a cantilever at the front, so that it is supported so much if it is placed far from the center of gravity of the support device. The device is easy to peel off. Therefore, it is better to design the arm part with such a length that the in-vehicle device does not protrude forward from the base part when it extends horizontally forward (parallel to the upper surface of the base part) Should be behind).
The shape of the “arm portion” is not particularly limited. For example, the “arm part” may be configured separately from the support part, but the “arm part” may be formed by integral molding with the support part (for example, a ball part).

In the means 19, the surface orthogonal to the axial direction of the arm portion is used as a reference surface, and the surface direction of the mounting surface of the device-side mounting portion is inclined with respect to the reference surface. The gist.
With such a configuration, in addition to the above action, the movable range of the support portion (ball portion) is widened. For example, in the case where such an inclination is not provided, if the support portion (ball portion) is arranged at a position where the support portion is swung downward, for example, if the surface direction of the mounting surface is directed downward, the vehicle is mounted further downward. The device can be arranged, and conversely, when the support portion is arranged at the highest position, the vehicle-mounted device can be arranged further upward. In addition, when the support portion is turned upside down as described above, the position of the in-vehicle device is changed, so that variations in the position are increased.

According to the present invention, since the sheet body placement portion is configured to be substantially flush by sealing the non-adhesive region by placing the lid member, the adhesive sheet body is firmly attached in the sheet body placement portion. As a result, the fixing force of the support device to the vehicle is improved.

Side view. FIG. 3 is a partially broken enlarged cross-sectional view of an end shape of a base plate 2.

Hereinafter, specific embodiments of a support device for an in-vehicle device according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 8, as an in-vehicle device (electronic device), for example, a support device 1 for a radar detector includes a base plate 2 as a base portion, and a base plate 2 and a storage case 3 as a hollow case portion. ing. Here, the size of the display screen of the radar detector supported by the support device 1 is particularly preferably about 1.5 to 3.5 inches.
The base plate 2 and the storage case 3 are hard polycarbonate molded products integrally formed by a mold. In this embodiment, unless otherwise specified, the forward direction refers to the left side of the figure in FIGS. 3A and 3B, and the rear direction refers to the same right direction.
The base plate 2 forms a solid plate body having a square shape with a side of 47 mm. The upper surface (front surface) 2a of the base plate 2 is formed in a smooth plane, and a storage case 3 is formed at a rear position of the upper surface 2a. A connecting portion between the upper surface 2a of the base plate 2 and the storage case 3 is smoothly connected. A joint portion between the upper surface 2a and the outer edge 2b of the base plate 2 (that is, a corner portion of the front-side base plate 2) is smoothly joined in a chamfered shape. The back surface 2c of the base plate 2 is also formed in a smooth plane, and an opening 5 is formed as a poor adhesion region at a rear position of the back surface 2c.

As shown in FIGS. 5A and 5B, the sheet body surrounding portion 4 is formed on the back surface 2 c of the base plate 2, at a position slightly inward from the outer edge 2 b of the base plate 2. The surface surrounded by the sheet body surrounding portion 4 is an area where an adhesive sheet body S described later is attached. The sheet body surrounding portion 4 is a ridge body having a rectangular cross section that is unbroken in the middle of enclosing substantially the entire back surface 2 of the base plate 2 along the outer edge 2 b of the base plate 2.
In the present embodiment, as shown in FIG. 9, the sheet surrounding portion 4 is configured with a width of 0.8 mm centering on a position 1.5 mm from the outer edge 2b of the base plate 2, and the sheet surrounding portion from the back surface 2c on the outside. 4, the amount of protrusion downward from the front end surface is 0.5 mm, and the amount of protrusion from the front surface of the sheet surrounding portion 4 to the lower side is 1.0 mm from the inner back surface 2 c. 2c is formed so that the inner side surrounded by the sheet surrounding portion 4 is slightly deeper than the outer side. In the following embodiments, the inside of the back surface 2c surrounded by the sheet body enclosing portion 4 is defined as a sticking surface.

As shown in FIG. 5B, the opening 5 is formed in a substantially half-moon shape that is mirror-image-symmetric with respect to the center line p passing through the front-rear direction of the base plate 2, and communicates with the inside of the storage case 3. Since the opening 5 is also a path for the mold formed when the mold is released from the storage case 3 formed by the mold, the lowermost end portion of the inner peripheral surface of the storage case 3 is the opening 5. Thus, it is a passage into the storage case 3. As shown in FIG. 5 (b), the position of the curved front end 5 a of the opening 5 is arranged slightly behind the center of the base plate 2, and the linear rear end 5 b is the outer edge 2 b on the rear side of the base plate 2. Are arranged in parallel. As shown in FIGS. 4A and 4B, the rear end 5 b of the opening 5 is arranged flush with the inner side surface of the sheet surrounding portion 4 that extends along the outer edge 2 b on the rear side of the base plate 2. Is done. Engaging claws 6 are formed at the front end 5a and the rear end 5b of the inner periphery of the opening 5 as engaging means for engaging with the lid 7 side.
As shown in FIGS. 2, 4 (a) and 4 (b) and FIGS. 5 (a) and 5 (b), a hard polycarbonate lid 7 is fitted into the opening 5. The lid 7 is a substantially half-moon shaped plate-like member corresponding to the shape of the opening 5. Engagement recesses 8 are formed on the front end 7a and rear end 7b of the lid 7 as engagement means that form an engagement relationship with the engagement claws 6 formed in the opening 5. By pressing the lid 7 against the opening 5, each engagement recess 8 is engaged with the engagement claw 6 in a force-fit manner, and the opening 5 is closed by the lid 7. As shown in FIGS. 4A and 4B, the lid 7 is closed and the back surface 2 of the base plate 2 and the outer surface thereof are arranged flush with each other. Further, as shown in FIG. 5A, the outer shell of the lid 7 is slightly smaller than the inner periphery of the opening 5, and thus a very small gap is formed between them. This level is used when there is no gap. Since there is no difference above, it is judged to be the same range.

The storage case 3 is formed mirror-symmetrically with respect to the center line p. The storage case 3 is a hollow body formed with a predetermined thickness, and has a front wall 3a in which a front opening 10 communicating with the inside and outside of the storage case 3 is formed, and the front wall 3a is disposed back to back and configured to be a flat surface. A basic outer peripheral shape is constituted by a rear wall 3b having a surface and a side wall 3c that is disposed between the front wall 3a and the rear wall 3b and forms a curved belt-like surface extending from left to right. . The front opening 10 is opened in a perfect circle shape, and is formed so as to expand toward the front so that the diameter increases toward the front (outward) in the thickness direction of the front wall 3a.
The shape of the storage case 3 will be described in more detail.
In the storage case 3, the surface side (hereinafter referred to as the front wall surface A) configured as a plane of the front wall 3 a is inclined rearward with respect to the upper surface 2 a of the base plate 2 when viewed from the side shown in FIG. (In this embodiment, an angle of 20 degrees with respect to the vertical direction). Similarly, the surface side of the rear wall 3c (hereinafter referred to as the rear wall surface B), which is configured in a plane, is disposed such that the upper side is inclined forward with respect to the upper surface 2a of the base plate 2 (however, the rear wall surface B is in the vertical direction). Since it is at an angle of 5 degrees with respect to the appearance, it looks like an image that stands almost vertically in appearance). Since the front wall surface A is inclined backward and the rear wall surface B is inclined forward, the side wall 3c is formed wider toward the lower side (base plate 2 side) and narrower toward the upper side. Since it is such a structure, there exists an effect which the metal mold | die which shape | molded the storage case 3 becomes easy to release.
When viewed from the front shown in FIG. 7, the surface side of the side wall 3c (hereinafter referred to as the side wall surface C) is shaped so as to cut out the vicinity of the vertex of the graph of the quadratic function whose upper side is slender. The maximum left-right width of the storage case 3 is narrower than the left-right width of the base plate 2 (in this embodiment, the left and right outer edges 2b of the base plate 2 are positioned inward by 8 mm on each of the left and right sides).

In the front view (plan view) from the upper side shown in FIG. 6 and the cross-sectional view shown in FIG. 3B, the lower area 2/3 of this position is perpendicular to the corner where the front wall surface A and the side wall surface C intersect. A chamfered corner surface D configured as if cut out is formed. As shown in the cross-sectional view of FIG. 3B, the corner surface D is formed in a gently curved shape so as to protrude outward. Here, if such a corner surface D is not formed and the front wall surface A and the side wall surface C facing each other in the front direction intersect with each other as they are, the intersection position at the position of the imaginary line q in FIG. Therefore, the storage case 3 protrudes to the front position of the base plate 2 considerably.
As shown in FIGS. 2, 3 (b), 4 (a) and 4 (b), and 5 (b), a ball holder 13, which will be described later, is disposed on the inner surfaces of the front wall 3 a and the side wall 3 c of the storage case 3. Positioning ribs 12 that also serve as reinforcements are formed.
In addition, the joining part where each surface of the front wall surface A, the rear wall surface B, the side wall surface C, and the corner surface D is joined is not discontinuous, and is smoothly joined in a chamfered shape.

A ball holder 13 as a ball holding portion and a ball portion 14 held by the ball holder 13 are disposed in the storage case 3. The ball holder 13 and the ball portion 14 constitute a ball joint mechanism. A device holder 16 is integrally formed on the ball portion 14 via an arm portion 15. The ball holder 13 is a flexible molded product made of synthetic rubber, and the ball portion 14, the arm portion 15, and the device holder 16 are hard polycarbonate molded products integrally formed by a mold.
2 to 4B, the ball holder 13 includes a plate-like main body portion 17 having a shape corresponding to the curved shape of the side wall 3c of the storage case 3, and a flange protruding forward of the main body portion 17. Part 18. The shape of the front edge portion 20 of the flange portion 18 is a perfect circle shape. The front edge portion 20 serving as the entrance (insertion port) of the ball portion 14 is formed to expand toward the front so as to have a larger diameter toward the front (outward) in the thickness direction of the flange portion 18. A ball holding surface 19 as a concave portion formed in a spherical shape is formed inside the ball holder 13, that is, on the inner peripheral surface of the flange portion 18 and the inner peripheral surface of the main body portion 17. The ball holding surface 19 is configured with a spherical surface larger than the hemisphere because the fitted ball portion 14 easily falls off when the curved surface is configured with a spherical surface smaller than the hemisphere. The surface direction of the front edge portion 20 of the flange portion 18 is an angle of 20 degrees with respect to the vertical direction. This is the same as the inclination angle of the front wall surface A of the storage case 3.

When the ball portion 14 is inserted into the ball holding surface 19 from the front edge portion 20 side, the entire flange portion 18 is pushed and expanded by the ball portion 14 that is forcibly fitted, and the ball portion 14 is fitted and the ball portion 14 is held. The amount of spherical surface and the diameter of the spherical surface are set so as to allow stepless rotation with respect to the surface 19. 3, 4A and 4B, the phantom line r is the position of the ball holding surface 19 before being expanded by the ball portion 14 (the ball holding surface 19 is moved to the ball portion 14 by being expanded). Is consistent with the outer peripheral surface).
One communication hole 23 is formed from the ball holding surface 19 to the back surface side of the main body portion 17. In the present embodiment, the diameter of the communication hole 23 is 1.2 mm, and the axial direction of the communication hole 23 is the center direction of the front edge portion 20. In the present embodiment, the axial direction of the communication hole 23 is set so as to coincide with the mold release direction from the ball holder 13 when the ball holder 13 is molded.

The ball part 14 is a solid sphere (however, the bottom part appears as a flat surface because the burr of the gate is cut at the time of molding), and the ball part 14 has a solid cross-section from the surface. The arm part 15 is extended. The axial direction s of the arm portion 15 (hereinafter simply referred to as the axial direction s) coincides with a straight line passing through the center of the ball portion 14. The device holder 16 formed at the tip of the arm portion 15 is composed of a plate-shaped holder main body 21 and an engagement hook 22 engaged with a radar detector formed on the left and right sides of the holder main body 21 arranged horizontally. Has been. The front surface of the holder body 21 is a device mounting surface 21a that is in direct contact with the radar detector.
As shown in FIGS. 4A and 4B, the surface direction t of the device mounting surface 21a of the holder main body 16a with respect to the axial direction s is relative to the surface (reference surface) orthogonal to the axial direction s. It is inclined at a predetermined angle toward the direction (in this embodiment, an angle of 12 degrees with respect to the direction orthogonal to the axial direction s).

The ball holder 13 is stored in the storage case 3 through the opening 5. With the ball holder 13 stored in the storage case 3, the opening 5 is sealed with the lid 7. In this state, the ball holder 13 is firmly fixed in the storage case 3. At this time, as shown in FIGS. 4A and 4B, the center of the front opening 10 formed in the front wall 3a of the storage case 3 and the front edge 20 of the flange 18 of the ball holder 13 is the same. In addition, the central axes are also aligned. In addition, the rear end position of the front edge portion 20 is connected substantially smoothly over the entire circumference with respect to the front end position of the front opening 10 that is expanded toward the front.
The ball portion 14 is fitted into the ball holding surface 19 of the ball holder 13 from the front opening 10 of the storage case 3 in a state where the ball holder 13 is stored in the storage case 3. With the ball portion 14 held by the ball holder 13, the arm portion 15 and the holder 16 are exposed (projected) forward of the storage case 3 as shown in FIGS. 4 (a) and 4 (b). The ball portion 14 is rotatable in the circumferential direction of the arm portion 15, and is swingable to the maximum at a position where the outer periphery of the arm portion 15 contacts the inner periphery of the front opening 10 of the storage case 3.

Next, the operation of the support device 1 configured as described above will be described.
Adhesive mat M (a 3 mm thick mat attached with double-sided tape in this embodiment) is attached to the attachment surface of back surface 2c of support device 1, and is suitable for visual observation such as a dashboard of a vehicle. It shall be fixed at an arbitrary position. Since the sheet body surrounding portion 4 is disposed slightly inside from the outer edge 2b of the base plate 2 in the attached state, the sheet body surrounding portion 4 cannot be confirmed unless visually observed from a lateral direction facing the outer edge 2b or an angle close thereto. Therefore, when the outer edge 2b of the base plate 2 is visually observed from a position above the normal base plate 2, a visual effect that the thickness including the protruding amount of the sheet body surrounding portion 4 does not appear thick is produced.
6 to 8B show a state in which a horizontally long radar detector is attached to the device holder 16 so that the longitudinal direction is the horizontal direction. As shown in FIG. 7, in the state where the radar detector is arranged horizontally, the holder main body 16a is arranged horizontally, and the engagement hook 22 is attached to a slit-like engagement portion (not shown) formed at the lower position of the back surface of the radar detector. Slide in and connect. In this connected state, the device mounting surface 21a is brought into close contact with the lower plane position of the radar detector.
As shown in FIG. 6, in a state where the arm portion 15 is extended in the forward direction along the center line p (shown in FIG. 5B), the radar is always radar even if the arm portion 15 is swung up and down. The front surface of the detector does not protrude from the outer edge 2 b on the front side of the base plate 2. That is, the center of gravity position of the total weight with the support device 1 always exists in the base plate 2 regardless of the weight of the radar detector.

Also, as shown in FIG. 6, when the radar detector is disposed relatively downward (for example, when the arm portion 15 extends horizontally or downwards from the horizontal), the radar detector is moved as shown by an arrow. When it is swung, it can be swung left and right until it interferes with the corner surface D.
As shown by the arrows in FIG. 7, the radar detector can rotate in the circumferential direction of the arm portion 15 until the radar detector abuts against the vehicle side to which the base plate 2 or the support device 1 is fixed.
FIG. 8A shows a state in which the radar detector is attached to the device holder 16 with the device mounting surface 21a facing downward when the ball holding surface 19 is disposed horizontally in the axial direction s in FIG. 4A. is there. On the other hand, FIG. 8B shows a state in which the radar detector is attached to the equipment holder 16 with the equipment mounting surface 21a facing upward when the axial direction s is horizontally arranged in FIG. 4B. In the present embodiment, the inclination direction of the ball holding surface 19 with respect to the direction orthogonal to the axial direction s is thus arranged in the vertical direction. By attaching the radar detector as shown in FIG. 8A, the radar detector can be disposed at an upper position further away from the base plate 2 as compared with the case where such an angle is not provided. On the other hand, by attaching the radar detector as shown in FIG. 8B, the radar detector can be attached to the base plate 2 even when the arm portion 15 is swung downward most compared to the case where such an angle is not provided. It is possible to dispose it at a position relatively close to the base plate 2 without being brought into contact with each other.

The support device 1 according to the embodiment having the above-described configuration has the following effects.
(1) The opening 5 formed on the back surface 2c (sticking surface) of the base plate 2 is sealed by the lid 7, and the entire back surface 2c surrounded by the sheet body surrounding portion 4 is formed on a flat surface. Therefore, the adhesive mat M will be firmly attached to the attachment surface, and the fixing force when the base plate 2 is installed on the vehicle side will not vary between different regions in the attachment surface, The support device 1 is fixed with a stable fixing force.
(2) Since the center of gravity of the supporting device 1 is present at the front side of the base plate 2 due to the weight of the radar detector supported in a cantilever shape at the front position of the base plate 2 in the first place, the base plate 2 is always located at the rear side of the base plate 2. Rotational force that lifts up will act. The opening 5 formed in the back surface 2c of the base plate 2 is formed in a large area at the lower position of the storage case 3 disposed at the rear position of the base plate 2, so that if there is no lid 7, the adhesive mat M In the opening 5 position, there is no fixing force, and the fixing force on the rear side of the base plate 2 is attenuated. In that case, there is a possibility that the adhesive mat M is peeled off from the sticking surface without resisting the rotational force, and the support device 1 may fall to the front side, but this is not the case in the present embodiment. .
(3) Since the back surface 2c of the base plate 2 is surrounded by the sheet surrounding portion 4, the pasting area of the adhesive mat M is clear and there is no mistake in pasting. Further, since the sheet body surrounding portion 4 is formed slightly inside the outer edge 2b of the base plate 2, when the outer edge 2b of the base plate 2 is viewed from a position above the normal base plate 2, the amount of protrusion of the sheet body surrounding portion 4 is increased. This creates a visual effect that it does not look as thick as the included thickness.
(4) Even if there is a small space such as a screw hole, the fact that it is not blocked does not significantly affect the fixing force of the support device 1. However, a large hole (opening region) is necessary because the opening 5 needs to secure a length in the storage case 3 that can support the ball portion 14 as described above. Since the opening 5 occupies about 1/3 of the sticking surface, the influence on the fixing force when the large space is not blocked is large. In the present embodiment, such a large opening 5 is sealed by the lid 7, so that the fixing force of the adhesive mat M is not attenuated.

(5) Since the front wall surface A of the storage case 3 has a shape in which the upper side is inclined rearward, the radar attached to the tip of the arm portion 15 is compared, for example, assuming that it has a front wall surface that stands vertically. When the detector is an embodiment, the amount of upward swing is greater (it is less likely to interfere with the storage case 3). As a result, for example, when the support device 1 is set at a low position in the vehicle, the display unit of the radar detector can be directed larger upward, and the number of places where it can be arranged increases.
(6) Since the corner surface D is formed in a chamfered shape at a position where the front wall surface A and the side wall surface C of the storage case 3 intersect, the radar detector is disposed at a position relatively close to the base plate 2. In this case, when the position of the virtual line q in the case where the corner surface D in FIG. 3B is not formed when the radar detector is swung in the left-right direction, the radar detector can be swung more greatly. The tolerance of the orientation of the detector display is improved.
(7) The center and central axis of the front opening 10 and the front edge 20 coincide with each other, and the rear end position of the front edge 20 relative to the front end position of the front opening 10 expanded forward is Since the connection is made almost smoothly over the entire circumference, there is no unbalanced direction over the entire circumference in the range in which the arm portion 15 can swing.
(8) When the arm portion 15 is turned upside down, for example, when the axial direction s in FIG. 4A is horizontally arranged as described above, the radar is applied to the device holder 16 with the device mounting surface 21a facing downward. With the state where the detector is attached and the state where the radar detector is attached to the device holder 16 with the device mounting surface 21a facing upward when the axial direction s of FIG. Since the swing range of the radar detector is changed, variations in the arrangement positions of the radar detectors are increased.
(9) The storage case 3 is closest to the rear side of the base plate 2, and the center of gravity of the support device 1 is set to the rear as much as possible so that the rear wall surface B is arranged along the outer edge 2 b of the base plate 2. For this reason, the arm portion 15 can be designed to be relatively long, so that the swing range of the radar detector is widened. In addition, the radar detector arranged at the front position tends to be particularly heavy on the front side display portion. In this way, since the storage case 3 is arranged as far back as possible, the radar detector is supported. The center of gravity can be set at a position close to the center of the base plate 2. When the center of gravity is unevenly distributed from the center, a rotational force is generated, which becomes a force for peeling off the base plate 2, but such a force can be suppressed in the configuration as described above.
(10) Since the communication hole 23 is formed in the ball holder 13 from the ball holding surface 19 to the back side of the main body portion 17, the air remaining inside when the ball portion 14 is fitted to the ball holding surface 19. Is discharged to the outside air through the communication hole 23, and there is no possibility that the ball portion 14 is pushed out of the ball holding surface 19 by the air remaining inside.
