Description

[Detailed Description of the Invention] "Industrial Application Field" This invention relates to a telescoping fixing device for a telescoping column for mounting a shelf or the like.

``Conventional technology'' Conventionally, in order to adjust the length of the column to match the vertical spacing of the mounting part, it has been used as a column for mounting a shelf by slidingly inserting both large and small columns into each other. Many types of devices have been devised and put into practical use in which the mating portion is tightened and fixed using screws and nuts.

"Problems to be solved by the invention" By the way, in the telescopic fixing part of the column,
A nut is screwed onto the inner end of a tightening screw that is inserted from the front of the outer column into one of the multiple engagement holes arranged in a row on the inner column. The position of the engagement hole at the lower end of the inner column, which is hidden in the inner column, is difficult to confirm from the outside, so after trying to insert it many times while trying to figure it out in the dark, I finally managed to insert the screw. The method of screwing a nut onto the inner end was unavoidable, but it was clumsy and the operation took a long time.

Therefore, in the present invention, in order to eliminate the clumsy method mentioned above and to quickly and reliably expand and contract the column, it is easy to align the position of the engagement hole of the inner column with the extension of the tightening screw. In addition, the purpose is to eliminate the screwing of nuts so that the inner end of the tightening screw can be directly tightened to the front wall of the inner column, and to make this expansion/contraction fixing operation efficient and accurate. .

"Means for Solving the Problem" In order to achieve the above purpose, a screw hole is provided near the upper end of the front surface of the outer column into which the inner column is slidably and retractably inserted, and a tightening screw is inserted into the screw hole. A plurality of recesses into which the inner ends of the tightening screws can be fitted are arranged in a row at equal intervals vertically on the front surface of the lower part of the other inner column, and the front surface of the outer column is inserted into the screw hole from the front surface. A peephole is opened upward or downward at a distance equal to the interval between the recesses on the front surface of the inner column.

``Function'' When the outer column and the inner column are slid together to adjust their overall length and are tightened with a screw, if the recessed part of the inner column is aligned with the rear of the peephole in the outer column, it will fit behind the screw hole. is sure to match with other depressions. Therefore, when a tightening screw is screwed into the screw hole in advance and the column is expanded or retracted, the position of the recess can be confirmed through the peephole even if the rear interior cannot be seen, and the recess where the screw should be fitted can be screwed in. Because it matches the back of the hole and the screw can be tightened immediately,
The operation of expanding and contracting the column is extremely easy and quick.

In addition, since both the inner and outer columns can be securely fixed by simply fitting the inner end of the tightening screw into the recess of the inner column and tightening, there is no need to insert a nut into the inner end of the screw. It is extremely easy to operate.

"Example" An embodiment of the present invention is shown in FIGS. 1 and 2.

In the figure, reference numeral 1 denotes an outer column, which has an opening with a lip groove shape in cross section facing rearward, and has a screw hole 1a in the upper end of its front surface.
A flange 1a' is provided on the front edge of the flange 1a' and a through hole 1b is provided above the flange 1a' as a peephole. A plurality of holes 1d are arranged in rows at equal intervals, corresponding to each other on the left and right sides, and a tensioner 3 is provided at the lower end.

A groove-shaped inner column 4 is inserted into the upper part of the outer column 1 so as to be slidable and expandable, and a plurality of recesses 4a are arranged in a row at equal intervals vertically on the front surface of the lower part of the inner column 4. The inner end 2a of the tightening screw 2 screwed into the recess 4a from the front surface of the outer column is engaged and tightened.
The peephole 1b is provided at a distance from the screw hole 1a equal to the interval between the recesses.

A contact plate 5 for the mounting portion is inserted into the upper end of the inner column 4, and its insertion piece 5a is fixed to the inner column front surface 4b with screws 6.
An elastic buffer 7 is attached to the upper surface of the contact plate 5.

The tension tool 3 has a screw rod 3b planted in the center of the lower end base 3a and extends upward, and a rotor 3c is rotatably screwed into the lower part of the screw rod 3b. A holding frame 3d, which is an S-shaped curved plate on the side surface, which surrounds the upper surface, lower surface, and one side of the rotor 3c and whose upper part is inserted into the lower end of the outer column is fitted in association with the holding frame 3d, and an insertion piece of the holding frame is inserted. 3e is screwed onto the front surface of the outer column with screw 8.

Reference numeral 9 in FIG. 2 is a shelf support, and by engaging the locking pieces 9a protruding on both sides of the rear end into the pair of left and right locking holes 1d of the outer column 1, the outer column can be held in a horizontal position. Supported at the front.

The structure of the telescopic support according to the present invention is as described above, and the pair of right and left supports are installed by extending between the upper and lower frames of a window frame, etc., and the shelf is erected by supporting the shelf support with both supports. However, the procedure for installing this support will be explained below along with its function.

As shown in FIG. 2, the upper and lower frames 11, 1 of the window section 10
In order to adjust the total length of the columns so that the distance between the columns 2 and 2 matches, the outer column 1 and the inner column 4 are slid and expanded and contracted to determine the length, and after tightening and fixing both with the tightening screw 2,
Insert this between the upper and lower frames. In this case, due to the elasticity of the elastic shock absorber 7 provided at the upper end of the column, the entire column is slightly stretched and fixed between the upper and lower frames, but since the tension force is extremely weak, a tensioning tool 3 is added at the lower end of the column. When the rotor 3c is turned in a predetermined direction, it rises along the screw rod and presses the entire column upwards via the holder 3d, so the column moves upward and the elastic buffer at the upper end is pressed even more strongly. As a result, the upper and lower ends of the pillars are crimped to the upper and lower frames, firmly fixing them, obtaining the supporting force of the shelf support, and by placing the pillars on the left and right sides, the shelf can be fixed. One or more shelves can be constructed at an appropriate height via the supports.

``Effect of the invention'' As a means for tightening and fixing both the inner and outer pillars, which are slidable and expandable, a plurality of depressions are arranged in a row on the front face of the inner pillar, and a screw hole is provided in the front face of the outer pillar, and a screw is screwed in through the screw hole. the inner end is fitted into the recessed part and tightened and fixed;
In addition, a peephole was provided in the front of the outer column so that the inside of the column could be seen through this hole and the position of the recessed part of the inner column could be confirmed. The operation of fixing the rack to the rack is extremely simple, quick, and reliable, thus improving the efficiency of the support installation work and making it easier to erect the shelf.

In addition, since the lower end of the outer column is equipped with a tensioner, the column can be stretched to the upper and lower frames and firmly fixed.
There is no need to use screws or nails at the post attachment part.
Installation is quick without damaging the mounting part,
Also, changing the mounting position is extremely easy.
