This is done by fixing the position of. Therefore, every time the screw ring is tightened or loosened, the clockwise force and the counterclockwise force are applied to the flexible adhesive piece 106b alternately in the horizontal direction. Generally, it is said that most of the adhesive force is based on the atmospheric pressure. Therefore, the adhesive force has a strong resistance to the force acting in the direction perpendicular to the adhesive surface, but the resistance to the horizontal force. Is less than a fraction of that.

Therefore, if there are fine irregularities on the surface of the dashboard to be bonded or there is a large undulation,
The adhesive strength is significantly reduced, so if the screw ring is tightened or loosened repeatedly, the adhesive strength will decrease.

And the cam In vehicle article support, characterized in that the is composed of an operating handle provided on the projecting end of the socket cap.

In the support according to the first aspect, by rotating the cam shaft, the spherical pressing cam presses and fixes the spherical body against the small diameter portion by the force acting in the direction perpendicular to the cam shaft. Since the force that rotates the cam shaft acts along the axial direction of the socket cap, the torque that rotates the socket cap along the plane orthogonal to the axial direction acts as in the conventional case. Therefore, the adhesive force between the mounting portion and the vehicle side is not impaired, and the operability can be fixed and released by rotating the operation handle half a turn.

The sphere pressing cam is sufficient in consideration of wear if the sphere can be moved in the axial direction of the socket cap by about 2 millimeters after coming into contact with the sphere. Therefore, the curvature of the cam surface is Very close to a circle, the operating handle can be smoothly moved and clamped or unlocked with a little force. The cam shaft that rotates together with the cam is
Both ends thereof may be passed through the socket cap, and bearings may be supported at the penetrating portions.

And a ball cap having a sphere housed in the cavity, a support pin extending from the sphere to the outside of the socket cap through the one end opening, and the sphere having the small diameter portion. And a pressing means for pressing and fixing to the socket cap, wherein the other end opening of the socket cap and the tip of the support pin is provided with an article support part on the other side and a mounting part to the vehicle side on the other side, respectively, The pressing means includes a cam receiving seat fixedly provided at the other end opening of the socket cap, a spherical pressing cam housed between the cam receiving seat and a spherical body, and the cam receiving unit that integrally rotates with the spherical pressing cam. Was erected on the seat The cam shaft is supported by the receiving portion so as to traverse the void in the diametrical direction and has one end protruding from the peripheral wall of the socket cap, and an operation handle provided at the protruding end of the cam shaft. The rotation of the spherical pressing cam causes the different diameter surface of the spherical pressing cam to come into sliding contact with the spherical body to press and fix the spherical body on the small diameter portion.

Since the bearing portion for supporting the cam shaft is erected on the cam receiving seat of the article support according to the second aspect, the spherical pressing cam is slidably contacted with the spherical body in the cam receiving seat. Supports the reaction force received when pressing. The cam floating seat is fixed to the socket cap side directly or via another fixing member. The cam receiving seat may also serve as a member for attaching to the vehicle.

A third aspect of the present invention is to provide a small-diameter portion having a substantially cylindrical void portion formed by narrowing the inner diameter in the vicinity of one end opening of the void portion and a notch portion communicating with the one end opening. And a ball cap having a sphere housed in the cavity, a support pin extending from the sphere through the one end opening to the outside of the socket cap, and pressing the sphere against the small diameter portion. An article support for a vehicle, which is provided with a pressing means for fixing, and which has an article support part on one side of the other end opening of the socket cap and the tip of the support shaft and an attachment part to the vehicle side on the other side. The pressing means includes a cam receiving seat fixedly provided at the other end opening of the socket cap, a spherical pressing cam housed between the cam receiving seat and a spherical body, and integrally rotating with the spherical pressing cam. Traverses voids diametrically The cam shaft having the other end penetrating the peripheral wall of the socket cap in the axial direction with an idle clearance and protruding outside the socket cap, and a drive handle provided at the protruding end of the cam shaft. By turning,
The article support device for a vehicle according to claim 1, wherein the different diameter surface of the spherical body pressing cam is brought into sliding contact with the cam receiving seat and the spherical body at the same time to press and fix the spherical body to the small diameter portion.

In the vehicle article support according to the third aspect, the spherical pressing cam is brought into sliding contact with the cam receiving seat and the spherical body simultaneously, so that the reaction force received from the spherical body is applied to the cam receiving seat via the cam. Is configured. Therefore. With the rotation of the cam, the cam shaft moves in the axial direction of the cylindrical void,
Move slightly. For this reason, in the penetrating portion where the cam shaft penetrates the socket cap, there is a gap that allows the cam shaft to move in the axial direction. It is usually sufficient that the gap is 1 to 2 mm. Further, since the camshaft does not need to support the reaction force from the spherical body, the end of the camshaft opposite to the side where the handle is attached does not need to be supported by the bearing portion.

In the article support defined by the above-mentioned first to third aspects, the sliding contact plate is interposed between the spherical pressing cam and the spherical body, so that the spherical pressing cam interposes the sliding contact plate. It can be configured to press the sphere. With this configuration, the sphere comes into contact with the sliding contact plate at one point and is accurately pressed in the axial direction of the cylindrical void portion,
The sphere does not receive the torque generated by the cam, and therefore the pressing and fixing force of the sphere does not vary. Further, the contact and abutting direction between the small diameter portion and the sphere is always accurate, which contributes to stabilization of the supporting and fixing force of the support. Further, direct contact between the cam and the sphere may result in contact between the cam surface and the point, and the contact area of the cam surface with the sphere may be scraped, which may deform the sphere or reduce the fixing force. However, if a sliding contact disk is interposed, this can be prevented.

The pressing surface of the spherical pressing cam may be an arc surface which gradually increases the distance from the center of rotation, but a large number of the surfaces gradually increase from the center of rotation. If the flat surface of the cam is configured to be continuous, the resistance force against the torque reaction force that the cam receives from the sphere or the sliding contact disk increases, and the cam displaces due to vibration and the fixing force becomes loose. Prevent it from getting lost.

The other bearing portion 7b has a U-shaped upper half portion, and rotatably supports the cam shaft so as to sandwich it. The protruding portion 8b near the central portion of the base plate 8 is in contact with the bottom surface of the cam floating seat 7 having such a configuration. In the above description, the cam receiving seat 7 and the base plate 8 are separate members, but it goes without saying that the cam receiving seat 7 and the base plate 8 may be integrally formed.

On the other hand, the pressing ring 10 is fitted from above onto the projecting edge portion 2c of the socket cap. Although not shown, the holding ring 10 is provided with a notch groove for passing the cam shaft when the socket ring is fitted from above, like the notch groove 2e of the socket cap. Between the base plate and the pressing ring 8b, a mounting portion 9 on the vehicle side (for example, the dashboard surface of an automobile) is provided.
, The flexible adhesive piece 9a is sandwiched between the base plate 8 and
If the vicinity of the peripheral edge of the press ring 10 and the vicinity of the peripheral edge of the pressing ring 10 are tightened and fixed by the fixing screw 12, the flexible adhesive piece 9 is clamped and fixed, and the cam receiving seat 7 is fixed by the base plate 8.

There may be a case where the lever handle 11 hits the dashboard surface and cannot rotate, but the lever handle 11 and the protruding end 6 of the cam shaft 6
Since the fitting portion with a has a regular polygonal shape, in that case, the lever handle may be temporarily removed, the mounting angle may be changed, and fitting may be performed again.

Since the maximum clearance between the cam 5 and the disc 14 is about 1 mm, in the case of the cam shown in FIG. 2, if the lever handle is rotated 90 to 150 degrees, it is firmly tightened. It can be fixed, and therefore, once the proper mounting angle is obtained, there is no need to attach or detach the lever handle. The male screw portion 6b of the camshaft 6 is screwed into the bearing portion 7a, and due to the reaction torque from the spherical body,
The purpose is to prevent the camshaft from reversing and losing the tightening force.

In the above-described embodiment, an example in which the spherical body is pressed through the sliding contact disk 14 has been shown, but as shown in FIG.
By omitting the circular plate, the surface of the base plate 38 fixed to the other end opening of the socket cap, which is exposed in the socket cap, is used as the cam receiving seat 37, and the cam receiving seat 37 and the spherical body 33a.
A spherical pressing cam 35 and a cam shaft 36 provided so as to rotate integrally with the spherical pressing cam are housed between the two. One end of the cam shaft 36 penetrates the peripheral wall of the socket cap with a play gap that allows vertical movement in the axial direction, and the lever handle 31 is attached to the protruding end thereof. The other end 36b of the cam shaft
Need not be supported at all, and may be left as a free end. However, when engaging with the socket cap, it is necessary to allow free movement in the vertical direction as shown in the drawing.

In the support having the above-described structure, the different diameter surface 35a of the spherical pressing cam 35 is brought into sliding contact with the cam receiving seat 37 and the spherical body 33a at the same time by the rotation of the cam shaft 36, so that the spherical body is moved. Press and fix to the small diameter part. At this time, the cam shaft
It will move up and down in the axial direction. In such an embodiment, the number of parts is small and the assembly is easy. In the above-mentioned two embodiments, the flexible adhesive piece was adopted as the mounting portion on the vehicle side. However, instead of the base plate, the top portion of the flexible shaft is fixed and the lower portion of the shaft is fixed to the vehicle. It does not matter even if it is fixed in place (for example, a seat fixing portion of a car).

[0029]

[Effect] In the vehicle component support of the present application, since the cam is rotated by the cam shaft that is orthogonal to the axial direction of the socket cap, the force for operating the cam shaft is mainly in the axial direction of the socket cap. Since the torque along the plane orthogonal to the axial direction does not act as in the conventional case, the mounting portion is not adversely affected. In addition, since it can be fixed and released with one touch, it has excellent operability.
