Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a telescopic column that is installed between the upper and lower frames of a window frame or wall to attach a shelf.

``Prior art'' There are many types of extensible columns for mounting shelves in the past.For example, the shelf column introduced in Publication of Utility Model Publication No. 58-8120 has a pipe column (first member) with a large diameter. A column 1 that is expandable and retractable by inserting a pipe column (second member) with a small diameter is fixed by aligning the engagement hole 5 formed in the first member with the elongated hole 4 formed in the second member. The length is fixed by inserting the screw 6, screwing the nut 7 onto the screw 6, and tightening it.A first mounting plate part 12 and a second mounting plate part 12 are attached to both upper and lower ends of the column 1 from both sides of the horizontal plate part 11. A fixing device 10 with a mounting plate portion 13 erected is screwed with screws 21, and both the front and rear mounting plate portions of the fixing device are inserted into the same portions using the gaps in front and behind the upper and lower side beams of the aluminum sash window frame. Attach the support to the window frame by tightening and fixing it with screws 21' from the front of the support, or by screwing in the wood screws 20 through the insertion holes 14 of the horizontal surface part 11 of the fixture for the upper and lower frames of the wooden window frame. It stands upright and has shelves attached to the front of a pair of left and right supports.

``Problems to be Solved by the Invention'' By the way, the above-mentioned shelf support should be made by fitting and tightening the upper and lower fixing devices of the support into the upper and lower sides of the aluminum sash window frame.
Or, it is used by fixing a fixture to a wooden window frame with wooden screws, but recently, most window frames have come to be made of aluminum sash, and the use of wooden window frames has disappeared. As the aluminum sash has become more sophisticated, there is almost no gap between the window frame side frame and the edge of the glass door, and there is no room to insert the support fixture into it, making conventional support support fixing methods impossible. As a result, the utility value of conventional shelf supports has decreased.

Therefore, in the present invention, as a means of fixing the shelf support to the window frame in order to respond to the advancement of window frames,
A support is inserted between the periphery of the window frame that protrudes forward from the upper and lower horizontal beams of the window frame, or between the upper and lower frames of the building that supports the outer periphery of the window frame, and the upper and lower ends of the support are extended in opposite directions. By adopting a method in which the shelves are attached and crimped to the upper and lower frames, it is possible to simplify the installation of the shelf-mounting struts, and to provide struts that can be installed and removed at will.

``Means for Solving the Problems'' In order to achieve the above-mentioned purpose, in a telescopic column formed by slidingly inserting both large and small tube columns with shelf mounting holes lined up in the front wall, the upper end of the inner tube column is A horizontal elastic stopper plate is attached to the outer tube column, a tightening adjustment device made of a screw rod and a rotor is provided at the lower end of the outer tube column, and a screw coupling device for both tube columns is provided at the insertion part of both the inner and outer tube columns, A vertically slidable slider is fitted inside both pipe columns, a screw hole is provided in the front wall of the slider, and a shelf mounting screw is inserted through the shelf mounting hole in the front wall of both pipe columns. The shelf is configured to be fixed to the front surface of the support column by screwing into the screw hole.

"Function" The function of the present invention will be explained together with the means for attaching the support.

Since this telescopic column can be adjusted to extend or contract by sliding both the inner and outer tube columns, first adjust the total length of the column to the length that will fit between the upper and lower frames of the window frame to which the column is to be installed. After determining this, screw and fix both pipe columns with the coupling tool provided at the fitting part, fit them into the window frame, and place the contact plate at the top end of the inner pipe column against the bottom surface of the upper stile, and then attach the outer pipe. Place the tightening adjustment tool at the bottom end of the column on the top of the lower stile, and then turn the rotor of the tightening adjustment tool in the specified direction.The threaded rod will extend downward, so the lower end of the adjustment tool can press the lower stile. As a result, the backing plate at the upper end of the inner pipe column presses against the upper stile due to the reaction, and since this backing plate has elasticity, it is pressed upward even more strongly as the lower end adjuster is tightened, causing the backing plate to press against the upper stile. At the same time as crimping, the lower surface of the adjuster is crimped to the lower stile by applying even pressure downward.

Therefore, this telescopic column can be strongly fixed within the window frame to which it is attached by generating a vertical tension force using the tightening adjustment tool, and can be easily removed by loosening the tightening of the tightening adjustment tool. Can be done.

``Embodiment'' In the accompanying drawings, FIGS. 1 to 3 illustrate an embodiment of the present invention. In the front wall 2 of the pipe column, there is a vertically elongated oval-shaped through hole 3 extending from top to bottom.
The lip edges 5, 5 are curved from the rear ends of the side walls 4, 4 to face each other, and a large number of cut grooves 6, which are equally spaced vertically, are formed in the left and right side walls. A tightening adjustment tool 7 is provided at the lower end, and the adjustment tool 7 is screwed onto the central raised part of the circular base plate 7a provided at the lower end. 7b, and the rotor 7c is screwed onto the threaded rod 7b, and the rotor 7c is surrounded on three sides from the lower side of the rotor 7c to the upper side of the rotor 7c, and extends upwardly in an inverted L shape. The supporting frame 7d has an S-shaped side surface.
After screwing the center of the upper inverted L-shaped insertion piece 7e to the screw rod 7b, insert the upper insertion piece 7e from the lower end of the outer tube, and screw it in by screwing the screw 8 from the front wall of the outer tube. There is.

Then, from the upper end opening of the outer tube column 1 to the inner tube column 9
is slidably inserted into the outer tube column, and the inner tube column 9 is formed into a groove shape with a rear opening and a width that allows the inner tube column 1 to be inserted in sliding contact with the inner surface of the outer tube column 1. A fixing piece 10 in the shape of a plane, with through holes 9b having the same shape as the through holes 3 in the front wall of the outer tube column arranged at the same intervals above and below the wall 9a, and screw holes 10a provided at both ends on the rear surface of the husband. is fitted and fixed, and the upper end has an elastic body 11 on the upper plane.
The downward insertion piece 12a of the T-shaped abutment plate 12 to which it is attached is inserted, and the screw 13 is used to tighten and fix it to the front wall of the inner tube column.

Reference numeral 14 denotes a locking plate, with a small hole 14b provided in the center of the vertical piece 14a, and a horizontal locking edge 14c formed by slightly bending the lower edge of the vertical piece 14a forward to the rear lip of the outer tube. After hooking it into the cut groove 6 provided in the
The inner tube column and the outer tube column are integrally connected by inserting a screw 15 through the small hole 14b and screwing it into the screw hole 10a of the fixing piece 10 at the lower end of the inner tube column.

Furthermore, 16 is a slider, in which a screw hole 16b is provided at the center of a vertical front wall 16a, and upper and lower horizontal walls 16c, 16c' bent from the upper and lower ends of the front wall toward the rear of the husband are the inner walls of the inner tube. Both protrusions 16d, 16 are protruded with a small width from the rear ends of both the upper and lower horizontal walls so as to be in sliding contact with the upper and lower horizontal walls.
d' is provided so as to protrude rearward from the column opening, and one or more sliders 16 are fitted into the inner tube column and the outer tube column, and the shelf support 17 is inserted into the front surface of the column.
When screwing and fixing with the screw 18, the through hole 3
The shelf support 17 is fixed to the support column by screwing the inner end of the screw 18 inserted into the screw hole 16b of the slider and tightening it.

FIG. 3 shows a side sectional view of how the telescopic support and the shelf support are attached.
The sliding parts of both the inner and outer pipe columns are fixed with the screws 15 and 15 to set the total length, and the upper end abutment plate 12 is elastically abutted against the lower surface of the upper stile 20 by the elastic body 11, and the tightening adjustment tool for the lower end of the column is set. By twisting the rotor 7c of No. 7 in a predetermined direction around the screw rod 7b, the screw rod 7b extends downward, so that the entire length of the column is extended to a certain extent, and the upper end elastic body is further compressed, thereby reducing the rebound. The force increases the tensile force of the strut against both frames, increasing the anchoring force of the strut.

Then, the shelf support 17 is attached to the vertically fixed pillar.
When installing, after determining the mounting height of the shelf support, insert the mounting screws 18, 18 through the through hole 3 in the front wall of the column, and slide the slider 16 up and down to the position of the mounting screw. By screwing the inner ends of the screws into the threaded holes of the slider, the shelf support is tightened and fixed to the support column.

In addition, 22 in Fig. 3 is a pipe shelf, and the shelf support 1
The front and rear ends are engaged with the front and rear frame rods 17a and 17b of No.7.

In addition, FIGS. 4 and 5 show another embodiment in which the telescoping column is composed of three tube columns, and there is another one on the top of the inner tube column 9 of the above embodiment. The outer tube columns 1' of the book are slidably inserted, and the T-shaped stopper plate 12 in the previous embodiment is inserted into the upper end of the upper outer tube column 1' by the same means, and the upper end of the inner tube column 9 is inserted. The same fixing piece 10 as the lower end is fitted to the lower end, and the other components are the same as those of the previous embodiment, but the slider 16 and screw 1
8 etc. are omitted. The purpose of its use is to widen the range of expansion and contraction of the telescopic strut.If you want to shorten the overall length of the strut, you can omit the upper outer strut 1' and connect the lower outer strut 1 and the inner By removing the abutment plate 12 inserted into the upper end of the upper outer tube column 1' and inserting it into the upper end of the inner tube column 9, the overall length can be shortened.

In addition, if the overall length of the column is desired to be long, the inner tube column 9 can be inserted between the lower outer tube column 1 and the upper outer tube column 1' to make the overall length longer. The method of standing up on the window frame etc. and the method of attaching the shelf supports are carried out in accordance with the previous embodiment. The overall length of the column is adjusted and maintained at a constant length by integrally connecting the three pipe columns using locking plates 14, 14 and sliding portion tightening and fixing means using screws 15, 15.

``Effect of the invention'' A large number of cut grooves are arranged in a row across the top and bottom of the outer tube column and the rear surface, a locking plate that locks into these grooves, and a screw inserted through the center hole of this locking plate. The sliding part of the telescopic support is tightened and fixed by the fixing piece provided at the end of the inner tube pillar for screwing, and the total length of the support is kept constant at the desired length, and this is fixed between the upper and lower frames of a window frame, etc. Can be installed vertically by matching. Therefore, since the cut groove, the locking plate, and the fixing piece are engaged and screwed together with screws, the fixed connection between the outer tube column and the inner tube column is reliable and strong, and is resistant to pressure in the length direction of the column. It is strong, and even when the rotor of the adjuster at the lower end of the column is twisted to extend the column between the upper and lower frames, the column does not shorten and its tensioning force increases.

In addition, by freely selecting a large number of cut grooves, the total length of the column can be adjusted as appropriate.
Further, fine adjustment smaller than the length of the interval between the cut grooves can be made by twisting the rotor of the adjusting tool provided at the lower end and moving the threaded rod in the center in and out.

Therefore, the expansion and contraction adjustment operation of the expansion and contraction support can be easily and reliably made, making it possible to freely adjust the expansion and contraction operation, and fine adjustments can also be made, and each fixed part does not collapse after the shelf is installed.It is a sturdy and reliable tension fixing. It is possible to provide telescopic struts of this type and achieve the desired purpose.
