Description

[Detailed description of the invention] This invention is a screen winding mechanism that can be used when installing wind-up insect screens, sunshades, blinds, etc. in openings in buildings, or when installing heat insulating screen devices in refrigerated show cases. This relates to a mounting bracket for attaching a screen box with a built-in screen box to a building opening frame, a refrigerating case, etc.

For example, when installing a roll-up type heat insulating screen device in a refrigerating case, it is necessary to attach a screen box for winding up the screen to an appropriate position on the refrigerating case. In such cases, the screen box is usually installed using some kind of mounting hardware, but the space for installing the screen box in the refrigerating case is generally very small, so it may be difficult to install the mounting hardware. In many cases, it is not possible to install it in the specified direction, so
Consideration needs to be taken, such as using mounting brackets of different shapes depending on each case.

In addition, when installing insect screens, sunshades, blinds, etc. equipped with similar screen boxes, the installation location and installation direction will be different.
Dedicated mounting brackets are required for each.

In view of the above, the present invention aims to provide a versatile mounting bracket that allows screen boxes to be mounted in various locations and directions according to various uses. It has a two-piece structure consisting of a fixing member for fixing it in place and a tightening member removably connected to the fixing member, and the screen box is sandwiched between these two members, and the fixing member is U-shaped. By forming two pieces perpendicular to each other as fixing pieces for fixing, and attaching the fixing member through either of the two fixing pieces, the mounting bracket can be attached in various locations and orientations. It is characterized by the following.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. Fig. 1 shows a case where the mounting bracket of the present invention is used to attach a heat insulating screen device to a refrigerating case; , 2 is a screen made of a fine mesh net that shields the front opening for heat insulation; 3 is a screen box for winding up the screen 2;
Reference numeral 4 indicates a mounting bracket for the scree box 3, and reference numeral 5 indicates an operating frame attached to the tip of the screen 2.

As is clear from FIG. 2, the screen box 3 is made of synthetic resin, aluminum, etc. and has a rectangular cross section, and has slit-shaped grooves 6 provided in the corners of its lower surface in the length direction. A winding shaft 7 for the screen 2 is rotatably supported inside the screen box 3, and the tip of the screen 2 wound on the winding shaft 7 is passed through the groove 6 to the front surface of the refrigerating case 1. It is derived.

The winding shaft 7 has a built-in spring so as to be twisted when the screen 2 is pulled out, and uses the elastic force in the winding direction accumulated in the spring due to the torsion as a driving source to move the screen 2. It is configured so that it can be automatically wound.

As is clear from FIG. 3, the mounting bracket 4 is composed of a fixing member 8 for fixedly attaching it to the refrigerating case 1, and a tightening member 9 connected to the fixing member 8. , these both members 8, 9
The fixing member 8 is formed into a substantially U-shape by arranging an auxiliary fixing piece 11 and a connecting piece 12 at both ends of a fixing piece 10 so as to face each other. The fixing piece 10 and the auxiliary fixing piece 11 are each provided with screw mounting holes 13, and the connecting piece 12 is fitted with a bolt 14 and a nut 15 for connecting the tightening member 9. The attaching member 9 is formed into an L-shape by a connecting piece 16 connected to the fixing member 8 and an abutting piece 17 abutting the screen box 3.
A long groove 18 is cut from the tip of the connecting piece 16, and the tightening member 9 can be removably connected to the fixing member 8 by fitting the bolt 14 into the long groove 18 and tightening the nut 15. However, a gap 19 is provided between the auxiliary fixing piece 11 and the abutting piece 17, which escapes from the opening groove 6 of the screen box 3 and allows the screen to be drawn out.

Further, the head 14a of the bolt 14 has a long groove 18.
A protruding part 14b is formed to fit into the protruding part 1.
4b functions as a rotation stopper for the bolt 14 when tightening the nut.

When installing the screen box 3 using the mounting bracket 4 having the above configuration, first,
The fixing member 8 is fixed to the freezing case 1 with screws 20. Next, the screen box 3 is fitted into the fixing member 8 in a predetermined direction, and in this state, the contact piece 17 of the tightening member 9 is brought into contact with the screen box 3, and the connecting piece 16 is inserted through the long groove 18. The screen box 3 is connected to the fixing member 8 by bolts 14 and nuts 15, and the screen box 3 is sandwiched between these members 8 and 9.

When removing the screen box 3 for repairing or replacing the screen, it is sufficient to loosen the nut 15 and remove the tightening member 9 from the fixing member 8. In this case, the fixing member 8 is fixed to the refrigerating case 1. It remains as it is.

In the above embodiment, the fixing member 8 is replaced by the auxiliary fixing piece 11.
The screen box 3 is fixed to the refrigerating case 1 via 3, the fixing member 8 may be fixed via the fixing piece 10. That is, the above-mentioned mounting bracket 4 selectively fixes the fixing member 8 through either the fixing pieces 10 or the auxiliary fixing pieces 11 that are perpendicular to each other, so that the fixing member 8 can be fixed depending on the mounting location and mounting manner of the screen box 3. It can be installed in the required direction.

FIG. 5 shows a case where the screen box 3 is attached to the upper surface of the refrigerating case 1.

In addition, in the above-mentioned embodiment, the case where the heat insulating screen device is installed in the refrigerating case 1 has been explained, but the above-mentioned mounting bracket 4 can also be used to install an insect-proof screen door, sunshade, blind, etc. equipped with a similar screen box in an opening of a building. Of course, it can also be used in any case.

As detailed above, according to the present invention, the mounting bracket has a two-piece structure consisting of a fixing member for fixing it to the mounting location of the screen box, and a tightening member removably connected to the fixing member, Since the screen box is sandwiched between these two members, the screen box can be easily and quickly attached or removed by simply attaching and detaching the tightening member. The two pieces that are orthogonal to each other are used as fixing pieces with screw mounting holes, so by attaching the fixing member through either of the two fixing pieces, you can attach the mounting bracket to the screen box installation location. It can be installed in the required direction depending on the installation method.
