Abstract

PROBLEM TO BE SOLVED: To attach an apparatus mounting clip to the top of a desk without spoiling the appearance of the desk so as not to bite fingers and thumbs, electric codes or the like. SOLUTION: A U-bent fixture 1 is formed at its upper piece 1a with an internally threaded cylinder 2 projecting therefrom, in which a fixture 3 is screwed at its support cylinder 4. The fixture 3 is formed with an operation cylinder 5 around the upper portion of the support cylinder 4 and an annular groove 6 at the lower end of the support cylinder 4. The annular groove 6 is adapted to elastically engage with an annular projected line 8 formed at the inner bottom of a bottomed cylindrical presser 7 such that the line 8 is held rotatable therein and detachable therefrom. The presser 7 is also formed on its side with a notch 9, in which the upper piece 1a of the fixture 1 is loosely fitted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clamp which can easily attach a device such as an illumination lamp to an appropriate position such as a tabletop of a desk.

[0002]

2. Description of the Related Art In a device on a desk top, for example, a desk lamp for lighting, a support base for stably supporting a lamp hinders the work.

As an apparatus for solving this problem, Japanese Utility Model Laid-Open No.
A device for mounting a pillar described in -80998 is known.

[0004]

However, in this device, when the grip is rotated, the gripper moves up and down the vertical piece of the mounting bracket, so that when the grip is moved downward, the grip is separated from the gripper. In addition to the loss of unity, the screw of the barrel is exposed, and not only the aesthetic appearance is lost, but also when moving upwards, the fingers or equipment cords are inserted between the upper surface of the holding body and the upper piece of the mounting bracket. And so on.

[0005] It is an object of the present invention to provide a clamp capable of mounting a device at a desired location such as a top plate without such a problem.

[0006]

The present invention has solved the above-mentioned problems as follows. (1) An attachment having a U-shape, a female screw cylinder projecting upward from the tip of a horizontal upper piece, and a support cylinder attached to the upper end of the support cylinder detachably screwed into the female screw cylinder from above. A fixing tool provided with an operation tube surrounding the upper portion, a cylindrical shape, a cutout on a side surface which can be loosely fitted to an upper piece of the mounting tool, rotatably engaged with a lower end of the support tube, and supported. And a pressure welding tool surrounding the lower part of the cylinder.

(2) In the preceding paragraph, the upper end of the press-contact member is brought close to or in sliding contact with the lower end of the operating cylinder.

(3) In the above item (1) or (2), the annular groove formed at the lower end of the support cylinder and the annular ridge formed at the center of the upper surface of the bottom of the press-contact member are elastically engaged.

(4) In any one of the above items (1) to (3), the outer shape of the lower end of the press fitting is made larger than the outer shape of the upper end.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings show an embodiment of the present invention, and are made of a synthetic resin fixture bent in a U-shape.
At the tip of the horizontal upper piece (1a) of (1), a female screw cylinder (2) is provided to protrude upward.

A bottomed support cylinder (4) of a synthetic resin fixture (3) is detachably screwed into the female screw cylinder (2) from above, and a slight gap is provided at the upper end thereof. An operation cylinder (5) surrounding the upper part of the support cylinder (4) is continuously provided, and an annular groove (6) is formed at the lower end of the inner surface of the support cylinder (4) immediately below the bottom plate.

An annular convex ridge (8) is formed on the outer peripheral surface of a raised portion (7a) provided at the center of the inner bottom surface of the press-fitting tool (7) made of a synthetic resin and having a bottom. On the side of 7),
A notch (9) is formed in the upper piece (1a) of the fixture (1) so as to be freely lifted and lowered. In addition, as shown in the figure, the pressure welding tool (7)
It is preferable that the outer shape of the lower end be larger than the outer shape of the upper end, and that the range in contact with the upper surface of a desk top or the like be large.

[0013] The pressing member (7) has an annular ridge (8) having a support cylinder.
It is elastically engaged with the annular groove (6) of (3), and is detachably and rotatably attached to the attachment (3). The upper end of the pressure contact (7) is always above the attachment (1). Projecting above the upper surface of the piece (1a),
It is close to or in sliding contact with the lower end of the operation cylinder (5).

In the above-described apparatus, as shown in FIG.
Pressing tool (7) together with support cylinder (4) by operation of operation cylinder (5)
Is raised, and the desk top plate (10) is inserted between the bottom surface thereof and the upper surface of the lower piece (1b) of the fixture (1), and the pressure welding tool (7) is lowered. Is fixed to the top plate (10),
For example, an arm of an illumination lamp can be inserted into the support tube (4), and the illumination lamp can be provided at a desired position on the top plate. Since the illumination lamp does not require an abutment, the top plate (10) The top can be widely used.

[0015]

The apparatus according to the present invention has the following effects. (a) According to the clamp of the first aspect, it is possible to easily attach / detach to / from the top plate by operating the operation tube, and dispose the electric device or the like supported by the support tube at a desired position on the top plate.

Further, since the upper part of the support cylinder is always covered with the operation cylinder, and the lower part of the support cylinder is covered with the press-contact member which moves up and down together with the operation cylinder, the external threads on the outer surface of the operation cylinder are not exposed, and the appearance is impaired. Never. Further, since the vertical distance between the operation cylinder that moves up and down and the press-contact member is always kept constant and does not fluctuate, there is no possibility that a finger, an electric cord, a piece of paper, or the like is pinched between them.

(B) In particular, when the upper end of the press-contacting tool is brought close to or in sliding contact with the lower end of the operating cylinder as in the clamp according to the second aspect, it is possible to reliably prevent a finger or an electric cord from being pinched therebetween. At the same time, the distal end of the female screw cylinder or the upper piece of the mounting tool is not exposed to the outside, and the appearance is good.

(C) According to the clamp of the third aspect, the press-fitting device can be easily attached and detached, and the press-fitting device can be removed and inspected or repaired and replaced at any time, which is convenient.

(D) According to the clamp of the fourth aspect, the contact range of the press-contacting tool which comes into contact with the top plate of the desk to which the device is to be mounted is increased, and the clamp itself, and eventually the device, is stably and reliably mounted. It can be fixed to a plate or the like.
