Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a tightening fixture used for attaching cards, etc. to bar members such as round pipes and square pipes, shelf boards, etc.

``Prior Art'' Conventionally, this type of tightening fixture is screwed and fixed to a U-shaped mounting bracket body and a lower support member of the mounting bracket body, and the bar member housed in the mounting bracket body is pushed. It consisted of a locking screw for pressure fixation.

For this reason, since the dimensions of the U-shaped part of the mounting bracket body are fixed, the bar members that can be attached are limited, and several types of U-shaped mounting bracket bodies with different dimensions must be prepared, making it difficult to handle. However, it has the drawbacks of being inconvenient and costly.

Furthermore, when a small bar member is clamped and fixed within the U-shaped mounting body, the mounting body protrudes more than the bar member, resulting in an unsightly appearance.

``Purpose of the Present Invention'' In view of the above-mentioned conventional drawbacks, the present invention aims to provide an easy-to-handle and relatively inexpensive tightening fixture that can be attached to bar members of different sizes without becoming unsightly. be.

"Means for Achieving the Object of the Present Invention" The present invention includes a column, an upper support member fixed to the lower end of the column, and a rod-shaped member integrally formed with one end of the upper support member and projecting downward. a support member, a vertical guide portion formed on the support member, a lower support member that is movable up and down guided by the guide portion, and a lock screw that is screwed into the lower support member and presses the support member. It is characterized by consisting of.

In addition, the present invention includes a column having a supporting part such as a card case formed at the upper end, an upper support member integrally molded with the lower end of the column and having an arcuate lower surface, and one end of the upper support member. a rod-shaped support member that projects downward and is integrally molded with the support member; a vertical guide groove formed in the support member; a plurality of locking recesses formed in the inner wall surface of the guide groove; a lower support member that moves up and down guided by a groove and has a step-like recess formed on its upper surface and has a support pin that is locked in the locking recess; It is characterized by consisting of a locking screw that presses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the embodiments shown in the drawings.

In the embodiment shown in FIGS. 1 to 9, reference numeral 1 denotes a support column, and a support portion 5 with ribs 4 is formed on the top of the support column 1, on which a card support member 3 to which a card plate 2 is attached is non-rotatably supported. ing.

Reference numeral 6 denotes an arc-shaped upper support member integrally molded with the lower end of the support column 1 and having both ends located below;
A rubber stopper 7 having an uneven surface for preventing slipping is fixed to the lower surface of the upper support member 6.

Reference numeral 8 denotes a quadrangular prism-shaped support member integrally molded with one end of the upper support member 6 and protruding downward, and the lower outer side surface 9 of the support member 8 is formed in an arc shape.
A recess 10 is formed on the inner surface.

Reference numeral 11 denotes a vertically long guide groove formed through the side surface of the support member 8, and a plurality of locking recesses 12 are formed on the inner wall side of the guide groove 11.

Reference numeral 13 denotes a lower support member attached to the support member 8 so as to be movable up and down. Consisting of support pieces 16, 16 formed at the rear end into which the support member 8 enters, and a support pin 17 that passes through the guide groove 11 of the support member 8 fixed to the support pieces 16, 16. has been done.

A lock screw 18 is screwed into a screw hole 19 formed in the lower support member 13 and presses the support member 8.

"Operation of the embodiment of the present invention" The tightening fixture 20 configured as described above has a bar member 21 such as a shelf board positioned between the upper support member 6 and the lower support member 13, and the lower support member 13 is connected to the upper support member 20. 6 and the bar member 21, the lower support member 13 is moved by the guide groove 11 of the support member 8, and the support pin 17 is positioned in the locking recess 12.

Thereafter, by tightening the lock screw 18, the tip of the lock screw 18 presses against the support member 8. Therefore, the lower support member 13 rotates around the support pin 17 in a direction to sandwich the bar member 21, and the bar member 21 is firmly sandwiched and fixed between the lower support member 13 and the upper support member 6. can.

In this embodiment, similar effects can be obtained even if the supporting member 8 is formed into a cylindrical shape.

"Different Embodiments of the Present Invention" Next, different embodiments of the present invention shown in FIGS. 10 to 16 will be described. In the description of these embodiments, the same components as those of the embodiments of the present invention will be designated by the same reference numerals and redundant explanations will be omitted.

The main difference between the embodiments shown in FIGS. 10 to 12 and the embodiments of the present invention is that the support member 8
Groove-shaped guide portions 22, 22 are formed on both sides of the lower support member 13A, and the guide portions 22, 22 are formed on the support pieces 16, 16 at the tip of the lower support member 13A, respectively.
In that the support pins 17A, 17A that move up and down are fixed, similar effects can be obtained even if the tightening fixture 20A is configured in this way.

The main difference between the embodiment shown in FIGS. 13 and 14 from the embodiment of the present invention is that the column 1A and the upper support member 6A are formed separately, and a threaded portion is formed at the lower end of the column 1A. 23 to the upper support member 6A
The groove-shaped guides are formed on both sides of the support member 8A to allow the support pins 17A, 17A of the lower support member 13A to be inserted from above. Part 2
2A and 22A, similar effects can be obtained even with the thus configured tightening fixture 20B.

The embodiment shown in FIGS. 15 and 16 is mainly different from the embodiment of the present invention in that a stepped recess 14A is formed on the lower surface of the upper support member 6B. With this configuration, it can be reliably attached to bar members of square pipes and round pipes.

In the above embodiment, the card support member is attached to the top of the support pillar, but the present invention is not limited to this, and a frame for storing cards may also be supported.

"Effects of the Present Invention" As is clear from the above explanation, the present invention has the following effects.

(1) A column, an upper support member fixed to the lower end of the column, and a rod-shaped support member integrally formed with one end of the upper support member and protruding downward;
It is composed of a vertical guide portion formed on this support member, a lower support member that is movable up and down guided by this guide portion, and a lock screw that is screwed into this lower support member and presses the support member. Therefore, it can be clamped and fixed between the upper support member and the lower support member even on round pipes, square pipes, and plate-shaped bar members. Therefore, it can be used by being attached to various bar members.

(2) According to (1) above, the lower support member can be moved up and down with respect to the support member, so the upper support member and the lower support member are in close contact with the bar member that is clamped and fixed, which is different from the conventional method. It does not become unsightly or create an unstable clamping condition as in the case of

(3) According to (2) above, round pipes of different sizes,
Can be securely attached to square pipes and plate-shaped bar members. Therefore, there is no need to prepare several types of different sizes as in the past.
It is economical and can reduce costs.

(4) Due to (1) above, the structure is simple and anyone can easily use it.

(5) Claims 2 and 3 also provide the same effects as the above (1) to (4).
