Relating to a fixing device for holding in position.

[Conventional technology]

As a conventional guide wire fixing device, for example, a technique described in Japanese Utility Model Application Publication No. 56-76896 is known. As shown in FIG. 6 of the accompanying drawings of the present application, the configuration according to this publication is such that a threaded pipe 23 is inserted through a seat plate 22 fixed to a lower frame 21 of the window, and a portion of the threaded pipe 23 that hangs downward from the seat plate 22 is inserted. A nut 24 is screwed onto the threaded pipe 23, a guide wire 7 is inserted into the threaded pipe 23, and a set screw 25 is provided at the head of the threaded pipe 23. Therefore, the guide wire is fixed integrally to the threaded tube, and by rotating the nut, the guide wire is tightened and fixed.

[Problem that the invention attempts to solve]

The above-mentioned conventional fixing device only fixes the guide wire in the threaded tube with a push screw, and when used in a blind installed outdoors, the guide wire is protected against abnormal loads caused by wind pressure, etc. The adhesion force is weak and reliability is poor. In addition, a threaded tube is a special bolt with a vertical hole drilled in the bolt, and if the diameter of the vertical hole is made thinner, it becomes difficult to insert the guide wire, and if it is made thicker, the strength of the bolt decreases. Since it has a special structure with vertical holes, it is a custom-made product and has disadvantages such as high cost.

This invention was devised in order to solve the above-mentioned problems, and it is an object to provide a guide wire fixing device for a blind that can securely fix a guide wire with high reliability and can be easily operated for fixing the guide wire. It is in.

This blind has the same structure as the conventional one, and the lower end of the guide wire 7 is fixed to a connecting piece 8. The adjusting bolt 9 is fastened to a support 10 such as a bracket projecting from the lower part of the window 1 in the building.

As shown in FIGS. 2 and 3, the connecting piece 8 is made of a square block made of synthetic resin or metal, and a groove 11 is formed in the vertically intermediate portion of the block to extend through both sides. A plurality of vertical holes 12 and 13 are provided in the upper part forming the upper wall of the groove 11, penetrating the groove 11 from the upper surface, and an opening 14 narrower than the width of the groove 11 is provided in the lower part from the side surface of both the vertical holes 12. , 13, and a pair of inward flanges 8a, 8a are provided. Furthermore, the connecting piece 8 is provided with a set screw 15 that protrudes into one vertical hole 13 and a set screw 16 that also protrudes into the groove 11. As shown in FIG. 3, both vertical holes 12 and 13 are opened to a thickness that allows the guide wire 7 to be inserted therethrough, and the head 9a of the adjustment bolt 9 is inserted into and removed from the groove 11 from the lateral direction. The opening 14 is fitted and supported by a pair of flanges 8a, 8a.
Similarly, the shaft portion 9b of the adjustment bolt 9 is formed to fit in and out from the lateral direction. Further, it is preferable that one of the vertical holes 12 and 13 without the set screw 15 is provided at the center of the width of the connecting piece 8. Furthermore, the adjustment bolt 9 has a lock nut 17 that contacts the upper surface of the support 10 that is fixed to the building body.
A tightening nut 18 is screwed into contact with the lower surface via a spring washer 19. Further, a through hole 20 through which an adjustment bolt 9 provided on the support body 10 is inserted is formed as a long hole in a direction parallel to the longitudinal direction of the slat 4.

Therefore, the means for fixing the guide wire 7 is as shown in FIG.
The guide wire 7 is tightened with the tightening nut 18 and the lock nut 17 to stand up, and the guide wire 7 is inserted into the vertical hole 12 drilled in the center of the connecting piece 8 from above from the top surface, and then, while bending the distal end of the guide wire 7, the guide wire 7 is inserted into the adjacent vertical hole 13.
The wire is inserted upward through the opening 14 and the groove 11, and the bent end of the wire is fixed to the connecting piece with the set screw 15, and then the head 9a of the adjustment bolt 9 is inserted into the groove 11. Then, fit the shaft 9b into the opening 14, align the core of the adjustment bolt 9 with the core of the guide wire 7 hanging down, and tighten the head 9 with the set screw 16.
a is fixed in the groove 11 and the guide wire 7 is tensioned and fixed by turning the tightening nut 18 after the end of the guide wire is thus connected to the support 10 of the construction. When tightening the tightening nut 18, it is preferable to clamp and fix the wire 7 with a tool such as a spanner so that the connecting piece 8 does not rotate together and twist the wire 7. Therefore, the connecting piece 8 is formed to a size that allows it to be held by a spanner or the like.

[Effect of idea]

The blind guide wire fixing device according to this invention involves bending and inserting the guide wire through a plurality of vertical holes in a connecting piece, fixing the bent wire portion with a set screw, and inserting the head of an adjustment bolt into the groove of the connecting piece. The shaft part is inserted into the opening, and the adjusting bolt is fastened to a support fixed to the building body with a tightening nut, and the guide wire is bent into a U-shape at the connecting piece and fixed with a set screw. Because it is worn,
Since most of the load is received at the bent part of the guide wire and the wire is strongly prevented from being pulled out, the connection between the guide wire and the connecting piece is reliably maintained over a long period of time, and it is protected against wind, etc. Even if an abnormal load acts on the blind, it can be supported without slack. In addition, there are grooves and openings below the multiple vertical holes drilled in the upper part of the connecting piece, and the lower and side surfaces of the connecting piece are open, so when inserting the guide wire through the multiple vertical holes, one side When pulling the end of the guide wire passed through the upper part of the vertical hole below the connecting piece and passing it through another vertical hole, the lower opening of the vertical hole is visible from the bottom and side of the connecting piece, so it can be inserted easily and quickly. It can be passed through the guide wire, and the operation of fixing the connecting piece to the guide wire can be easily performed. Furthermore, the adjustment bolt can be a regular bolt on the market, its length and thickness can be freely selected, and its head and shaft can be inserted laterally into the groove and opening of the connecting piece. Since it can be inserted, the connecting piece and adjustment bolt can be easily combined. In addition, since the core of the combined adjustment bolt can be fitted with the core of the guide wire, it has excellent durability as no torsional force is applied to the connecting piece, and it also prevents the piece from tilting. This allows the guide wire to be tensioned in a fashionable manner without giving too much tension.
