Description

  The present invention relates to a fixing tool for fixing a rod-like member to an end portion of a flexible sheet such as a woven fabric and a fixing method using the same.

  Since ancient times, as a wisdom of the ancestors to live comfortably in the hot summer, a method of hiding the sun from the eaves of a house or leaning a stand up against the wall to block direct sunlight and improve ventilation Has been. Recently, although air conditioners have become widespread, room temperature rises when sunlight enters the room from the window glass, causing problems such as insufficient air conditioning cooling capacity and increased power consumption. Although these sunshades that can be used have been reviewed, there is a problem that they are inferior in durability due to natural materials.

  On the other hand, in recent years, awnings, shades, western style bamboos, western style blinds, roll screens, etc., which use highly durable industrial products, such as fabrics, have been used, and air permeability is good. By using a woven fabric, ventilation can be improved, and by using fibers having high light shielding properties and heat shielding properties, heat can be prevented from entering the room.

  Moreover, these industrial products can be used not only on the wall surface of a house but also on the roof of a factory using a metal roof or on a carport, and temperature rise in the factory or in a car under hot weather can be prevented. In addition, because the air conditioner releases the indoor heat to the outside through the refrigerant according to the principle of the heat pump, if direct sunlight hits the outdoor unit and the temperature rises, the cooling efficiency decreases, and more power is consumed. Recently, in order to improve the cooling function, it has been used as a sunshade for air conditioners.

  However, these seats are flexible, unlike blinds and Yoshizu, so they can be folded and rolled up, and they can easily follow curved sections, but they cannot stand on their own. . Therefore, Patent Document 1 discloses a Western style column in which a light-shielding curtain is attached to a self-supporting column. A sunshade effect can be obtained by striking it between the ceiling and the floor that protrudes like a bowl.

  In the roll screen shown in Patent Document 2, by providing a weight bar on the lower edge of the screen via a locking member, the cloth can be suspended in a state of being stretched straight. Furthermore, in patent document 3, as both the shade which covers a ceiling part so that direct sunlight may not hit an air-conditioner outdoor unit, both ends of a sheet | seat are pulled with a support rod, and a sunshade roof is formed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the embodiments is merely illustrative in nature and is not intended to limit the present invention, its application, or its use at all.

FIG. 1 is a side view of the fixture of the present invention, and FIG. 3 is a perspective view. The fixture 1 is made of resin or metal and is formed of, for example, polycarbonate.

The fixing device 1 has a pair of fixing pieces 11 each having a bulging portion 12 that bulges structurally in one side and a sandwiching piece 13 whose one end extends in a plate shape, and the bulging portion faces outward. In addition, the joints 14 on the other end side are integrated with each other. Thereby, a storage space 15 in which the rod-shaped member 3 can be stored is formed.

Further, as shown in FIG. 2, the fixture 1 can be freely opened and closed between the closed state (a) and the open state (b) by the joint portion 14, so that the rod-shaped member 3 can be opened. It can be taken in and out of the storage space 15. In this example, a groove is provided on the outer side of the joint portion 14 so as to be thinner than the other portions so that it can be bent easily. For example, only the joint portion 14 can be made of a soft resin to give flexibility.

FIG. 4 shows a perspective view of the fixture 4 of the present invention. The fixture 4 is made of resin or metal, and is formed of, for example, stainless steel. The fixture 2 is externally fitted on the fixture 1 and fixes the sheet 2 to the rod-like member 3 via the fixture 1. The fixing bracket 4 basically has the same structure as the fixing tool 1, and two fixing bracket pieces 41 each including a bulging pressing portion 42, a sandwiching piece pressing portion 43 and a bracket coupling portion 14 are paired, The coupling portion 44 is fixed with, for example, bolts and nuts. Further, the fixing method is not limited to this, and the holding piece pressing portion 43 is closed in the closing direction by connecting the fitting connecting portion 44 with a spring or by integrally forming the two fixing fitting pieces 41 with an elastic material. The holding piece 13 is pressed with an urging force. As shown in FIG. 4, the fixing metal piece 41 is provided with reinforcing protrusions 45 toward the outside so that the fixing metal piece 41 is not deformed. The sheet end can be securely and firmly fixed.

Next, a method for fixing a weight bar (bar-shaped member) to a sunscreen (sheet) using these components will be described.

FIG. 5 is a perspective view showing a state in which the sheet end is fixed to the rod-like member, and FIG. 6 is a side view.
The end of the sheet 2 having a predetermined width of about 30 cm to 180 cm is wound around the rod-like member 3 and folded, an overlapping portion 21 having a depth of about several centimeters is provided, the clamping piece 13 of the fixture 1 is opened, and the storage space 15 is opened. The rod-shaped member 3 around which the sheet 2 is wound is fitted, the clamping piece 13 is closed, and the overlapping portion 21 of the sheet is clamped from both the front and back surfaces. Further, the fixing metal fitting 4 is fitted from above and the metal fitting coupling portion 44 is fastened with a bolt and nut, whereby the holding piece 13 is pressed by the holding piece pressing portion 43 and fixed so that the overlapping portion 21 of the sheet does not move.

  According to this method, it is not necessary to sew the overlapping portion 21, and anyone can easily process the sheet end portion and fix the rod-like member to the sheet end portion without trouble, and can be easily disassembled. In addition, if the overlapping portion 21 is used as an adjustment allowance for the dimension, it is a construction method that does not damage the sheet, such as making a hole in the sheet. Easy to use.

Furthermore, fraying from the end when using a coarse woven fabric for improving the air permeability of the sheet can be prevented, so that the state where the sheet is in focus can be maintained. Here, the method of fixing the rod-shaped member only to one end side of the sheet has been described, but the description of the fixing of the rod-shaped member and the sheet is the same for the other end side as well.

  The fixing device 1 may be provided at a necessary position as appropriate, and depending on the width dimension of the sheet 2, it may be provided at such an extent that the sheet does not float up at appropriate positions at both ends and the center (at intervals of several tens of cm). . In the case of the present invention, the width dimension of the fixture 1 is about 30 cm. However, a long member can be manufactured by extrusion molding of a resin, and can be used after being cut to an appropriate size. The width of the sheet 2 may be equal to the length of the rod-shaped member 3, or a plurality of sheets may be fixed to the rod-shaped member by narrowing the sheet width. In particular, when installing outdoors such as sunshade, the seat width is set to about 30 cm to cope with tilting by wind, etc., so that the risk of detachment of the fixture can be reduced even if it is blown by strong winds. . For example, six sheets 2 having a width of 30 cm may be attached to the rod-shaped member 3 having a length of 180 cm.

For example, the clamping piece 13 of the fixture 1 can be directly fastened with a bolt and nut without using the fixture 4, but in this case, a hole for passing a bolt or the like must be formed in a part of the seat. Therefore, it is difficult to disassemble and reuse the sheet 2 and the rod-shaped member 3. If reuse is not considered, the fixture 1 and the sheet 2 can be bonded.

The present invention can fix the sheet end to the rod-like member using a fixture that can be easily attached and detached, and can be applied to any sheet, so it is extremely useful and highly industrially applicable.
