[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support stand for mounting a television receiver, an amateur radio, and the like at a desired position in an automobile.

[0002]

2. Description of the Related Art Heretofore, as one type of a support stand of this type, a flexible support arm 5 has been used by using a fixing bolt or the like for fixing a seat of an automobile to a vehicle body.
2 is erected on the floor surface of the vehicle, and at the top thereof, as shown in FIG. A ball pin integrally provided with a sphere 55 is placed on the lower end of a support pin 56, and the support pin is projected by a substantially cylindrical socket cap 58 from the upper end opening of the socket cap. The sphere 55 is wrapped around the upper end of the support arm 50, and the sphere is clamped between the recess 52 and a small-diameter portion 59 formed by narrowing the inner diameter near the upper end opening of the socket cap, and attached to the support pin 56. While holding the television receiver 70 and the like at a desired angle, the socket cap pressing drive means including the tightening screw 60 provided on the socket cap 58 and the inclined surface 53 of the circumferential groove 54 is used. Driven push the socket cap downward Flip Press slope 53 in 60 of the tip, the sphere 55, the support stand to fix rigidly clamping pressure, are known.

[0003] Such a support stand sufficiently fulfills its purpose in the case of a very lightweight article, but as the functions of a television receiver and a radio become more sophisticated and the size thereof becomes larger, the size of the support stand becomes larger. The weight increases, and when the vehicle accelerates or decelerates, a large force acts on the support pins due to the inertial force applied to these heavy articles, the sphere slides, and the articles cannot be fixed in place. There was a disadvantage.

In order to cope with such a problem, it is conceivable to increase the size of the support stand or to increase the tightening force of the tightening screws. Yes, and even if you tighten the tightening force,
That the clamping force is dispersed in the contact area between the spherical surface and the concave portion 52 or the contact area between the spherical body and the small diameter portion 59;
Also, when the tightening screw 60 is tightened, the center line of the socket cap 58 and the center line of the concave portion 52 gradually shift, so that the pressing force for pressing the sphere 65 from above and below is biased, and the fixing force of the sphere is generated. Was not over a certain limit, and it was difficult to prevent the sliding of the sphere.

In order to enhance the fixing force of such a sphere,
As means, it is disclosed in JP-A-2-120151.
Place the sphere in the socket cap
Then, tighten the screw between the receiving base screwed to the fixing member.
It is also known to use a fixing member,
When tightening, the surface of the sphere will be
Television is often repeated because it will hurt
Each time you change the orientation of the installation screen,
Failure to deepen the abrasion and scratches of the members and reduce the fixing force gradually
There was a point.

[0009]

FIG. 1 shows an embodiment of the present invention. A support arm 30 has rigid metal wires 31a, 31a,... As a core material, and a helical tube is provided around the core material. 3
At the upper end of the flexible shaft 31 covered with 1b, a head 33 for attaching a member is provided. By crimping the shape part 34, it is integrally connected and provided. At the top of the head, a projection 35 is formed as a support for the ball pin 20, and a male screw 36 is engraved on the outer periphery of the head as a screw.

The lower end of the flexible shaft 31 is similarly attached to the mounting shaft 3.
7 are integrally connected, and a notch 38 formed by partially removing a side surface of the mounting shaft in the longitudinal direction is provided.
The L-shaped attachment piece 39 is fixed by the screw 39a, thereby forming an attachment portion on the vehicle side. The L-shaped piece is erected on the floor of the vehicle using, for example, bolts and nuts 82 for fixing the legs 81 of the seat of the vehicle to the floor 80 of the vehicle body.

On the support portion 35, a support pin 22 having a male screw portion 23 as a mounting portion to an article at a tip end, and a sphere 21 integrally provided at the base of the support pin 22 are provided. The ball pin 20 is placed in a state where the sphere 21 and the upper end of the support portion 35 are in contact with each other.

The ball pin 20 is loosely fitted so as to enclose a sphere with the substantially cylindrical socket cap 1 with the support pin 20 protruding from the upper end opening 2 thereof. The socket cap 1 has an inner diameter slightly larger than the sphere 21, and by narrowing the inner diameter of the upper end opening 2,
A small diameter portion 3 for clamping the sphere together with the bearing portion 35 is formed.

A projection 4 is provided at the lower end of the socket cap 1. Socket cap 1 is a sphere 2
When the socket cap 1 is covered and fitted, a slight gap is maintained between the lower end of the socket cap 1, that is, the protruding edge 4 and the stepped portion 36a provided on the head 33 of the support stand. On the protruding edge of this socket cap, together with the male screw portion 36, a tightening screw ring 6 constituting a pressing means of the socket cap.
Are engaged at the engaging edge 6a, and the female screw portion 7 of the tightening screw ring 6 is screwed to the male screw portion 36 on the outer periphery of the head. Reference numeral 5 denotes a vertical cutout provided in the side wall of the socket cap 1, which is connected to the upper end opening, and supports the article by turning the direction of the support pin close to a right angle with respect to the longitudinal direction of the support arm. Make the approach of the support pin in the case.

On the other hand, the support pin 22 has a slightly larger diameter than the male screw portion and a non-rotatable cross section (for example, a substantially kamaboko type cross section) between the male screw portion 23 and the support pin base. And a handle disk 25 formed of a disk having a hole having the same shape as the cross section of the mounting portion at the center thereof. Locked at 26. 27 is
The spacer is a spacer made of an elastic material that fits into the upper surface recess of the handle disk 25 and whose upper surface reaches the height near the base of the male screw portion 23.

[0015]

In the support stand having the above-described structure, the support arm 30 is fixed to the vehicle body side, and the support arm is bent at a desired angle as needed to adjust the posture. Next, the male screw part 23 at the tip of the support pin is applied to the article to be supported, for example, the female screw part for attachment of the television receiver 70, and the handle disk 25 is turned to move the support pin to the receiver side, Securely fix. In this state, if the direction of the image receiver 70 is determined and the fastening screw ring 5 is tightened, the sphere 21 is clamped by the support portion 35 and the socket cap 1 and is firmly fixed.

In the above embodiment, the bearing 35 may be formed in the shape of a mortar, but when the contact area with the sphere exceeds a certain level, the fixing force is rather reduced. Further, a peripheral wall 36b for guiding a socket cap provided around the support portion.
Is not always necessary.

[0017]

[Effect] The support stand according to the present invention is a ball pin
A fastening means keeps the socket cap even all around its circumference.
With equal force, press only in the axial direction of the socket cap
Works from the opposite direction to the tightening screw ring and this pressing force
The clamping force is fixed by the reaction force from the bearing,
Unlike the past, such as the surface of the sphere and the inner surface of the socket cap,
Wear and deformation occur on the sphere and the surface pressed against it
Strong fixing force is attenuated by use.
And therefore sudden displacement even during sudden braking
And safety is extremely high.

Furthermore, the posture of articles such as televisions should be improved.
The notch to the desired position.
It is necessary to fix it so that it
Is a member with a notch for the ball pin to enter.
A screw is engraved on the screw.
Therefore, in the final stage of screw tightening,
Since it is unpredictable whether you will turn, adjust your posture.
It was difficult, but in the case of this application stand,
And socket cap are separate parts, so the notch
