Description

TECHNICAL FIELD The present invention relates to a fixture set for fixing a plate-shaped heat insulating material to a glass plate of fittings such as a sash window and a sash door.

It has been proposed to attach a heat-insulating sheet to a glass plate of a sash window or a sash door in order to prevent cold air from entering a room from the glass plate in winter (see Patent Document 1).

JP 2014-240571 A

However, since the conventional heat insulating sheet is attached to the glass plate via an adhesive such as double-sided tape, there is a problem that it cannot be reused if it is peeled off from the glass plate during the off-season, and the adhesive remains on the glass plate. ing.

The present invention provides a fixture set for a heat insulating material for a glass plate that facilitates attachment and detachment of the heat insulating material to the glass plate of fittings and enables reuse.

A fixing tool set for a glass plate heat insulating material that enables a plate-shaped heat insulating material to be attached to and detached from a glass plate of a fitting,
The fixture set includes a plurality of fixtures,
The fixture includes at least two fork-shaped insertion portions inserted between the frame of the fitting and the sealing material or between the glass plate and the sealing material;
including a support portion connected to the insertion portion and supporting the heat insulating material,
The plurality of fixtures are
A fixture for a heat insulating material for a glass plate, characterized in that it supports the heat insulating material so that the heat insulating material faces the glass plate by being arranged opposite to each other so as to sandwich the heat insulating material in the surface direction of the heat insulating material. set.

According to this configuration, by arranging a plurality of fixtures so as to sandwich the heat insulating material in the surface direction of the heat insulating material, the heat insulating material is supported on the glass plate by the respective support portions of the sets of fixing tools that face each other. A heat insulating material is supported so as to face the glass plate. Therefore, since it is not necessary to attach the heat insulating material to the glass plate via an adhesive as in the conventional method, the heat insulating material can be easily attached and detached. Enables reuse of materials. When the insertion part is inserted between the glass plate and the sealing material with different frictional resistance, the sealing material with high frictional resistance is caught in the back side. However, since the insertion portion has at least two or more fork shapes, it can be smoothly inserted between the glass plate and the sealing material while suppressing the frictional resistance with the sealing material compared to the plate-shaped insertion portion. be.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a fixture set for a glass plate heat insulating material for fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that the fixture of the present embodiment can be used for fittings having a glass plate regardless of the size of the fittings such as sash windows and sash doors. Moreover, although the following embodiment describes the case where the heat insulating material is supported on the indoor side of the glass plate, it can also be supported so as to face the glass plate on the outdoor side.

<First embodiment>
As shown in FIG. 1(A), the fixture 1A is formed by bending a flat plate made of metal, plastic, or the like at both ends in the longitudinal direction at right angles to the direction of separation. That is, the fixture 1A includes a plate-like insertion portion 1a and a support portion 1c that extends from the insertion portion 1a and supports the heat insulating material 13. As shown in FIG. Here, the support portion 1c includes a receiving portion 1b that receives the edge of the heat insulating material 13 bent and continued in the horizontal direction from the insertion portion 1a, and a supporting portion that supports the surface of the heat insulating material 13 bent and connected from the receiving portion 1b. 1c.

The fixture 1A having the above configuration has the insertion portion 1a inserted between the glass plate 12 of the fitting 10 and the sealing material 14 (for example, a pressing rubber), and the glass plate 12 is sandwiched between the top of the frame 11 on the indoor side of the fitting 10. By bringing the receiving portion 1b into contact with the surface of the sealing material 14, attachment to the fitting 10 is completed. A plurality of fixtures 1</b>A are arranged to face four sides of the glass plate 12 . In this state, when four sides of a plate-shaped heat insulating material 13 having a size slightly smaller than the size of the glass plate 12 are inserted between the glass plate 12 and each of the support portions 1c, the heat insulating material 13 expands in the plane direction of the heat insulating material 13. A tensioning force of the heat insulating material 13 is applied to each receiving portion 1b of the set of the fixtures 1A arranged opposite to each other with the heat insulating material 13 interposed therebetween. Thereby, the heat insulator 13 is supported so as to face the glass plate 12 . Further, even when the heat insulating material 13 having a size that does not impart a tensile force to the receiving portion 1b is used, the surface of the heat insulating material 13 is abutted and supported by the support portion 1c. can do. In addition, although the insertion portion 1a of the fixture 1A in this embodiment has a tapered plate shape, it is not limited to this shape and may have another shape as long as it is a plate shape. The heat insulating material 13 is, for example, a single plate or a multilayer polycarbonate plate having a hollow (for example, one having a corrugated core between two polycarbonate plates). When a multilayer polycarbonate plate is used as the heat insulating material 13, the support portions 1c of the fixture 1A are formed in two fork shapes or three or more comb shapes, and the support portions 1c are pierced into the hollow portion of the central core for heat insulation. It may be configured to support material 13 . The support portion 1c bent vertically from the receiving portion 1b is within the depth width of the frame 11. - 特許庁Therefore, in the case of a sash window consisting of an inner shoji and an outer shoji, the sash window can be opened and closed.

In addition, the fixture 1A may press the bending portion between the receiving portion 1b and the supporting portion 1c in the width direction to form a bending groove. With this configuration, the support portion 1c is opened in front of the glass plate 12 to facilitate the insertion of the heat insulating material 13, and then the support portion 1c is bent toward the glass plate side so that the heat insulating material 13 faces the glass plate 12. It can be installed securely. When removing the heat insulating material 13, the supporting portion 1c is bent forward and widened.

<Second embodiment>
In this embodiment, configurations different from those of the first embodiment will be described in detail, and the same configurations will be given the same reference numerals.
As shown in FIG. 1B, the fixture 1B has an insertion portion 1a extending vertically downward from the same portion of the receiving portion 1b and a supporting portion 1d extending vertically upward. The support portion 1d may have the same shape and size as the support portion 1c on the front side of the frame 11, or may be larger or smaller than the support portion 1c.
A gap is formed between the glass plate 12 and the heat insulator 13 when the heat insulator 13 is inserted between the support portion 1c and the support portion 1d. The gap is smaller than the thickness of the glass plate 12 and smaller than the thickness of the heat insulator 13 . That is, the minute gap forms an air layer between the glass plate 12 and the heat insulating material 13, so that heat insulating properties can be improved.

<Third Embodiment>
The fixture 1C is attached to the corner of the frame 11, as shown in FIG. 1(C). That is, the fixture 1C has a receiving portion 1b formed by bending each of two oblique sides of a right-angled triangular supporting portion 1c perpendicularly, and an inserting portion 1a formed by bending each receiving portion 1b at right angles. The insertion portion 1a of this embodiment has a square shape, and the thickness of the insertion portion 1a decreases toward the distal end.

With this configuration, the corners of the heat insulating material 13 are firmly fixed to the corners of the glass plate 12, so cold air is further suppressed from entering the room through the glass plate 12, and heat insulation is improved. Note that the supporting portion 1c of the fixture 1C is not limited to a right-angled triangle, and may be a trapezoid in which the corners of the supporting portion 1c are cut so as not to come into contact with the corners of the frame. According to this configuration, it is possible to avoid deterioration in adhesion of the fixture 1C due to variations in the thickness of the sealing material 14 exposed at the corners of the frame.

<Fourth embodiment>
The fixture 1D of this embodiment has a hook shape when viewed from the side. That is, the fixture 1D has an insertion portion 1a parallel to and in contact with the top of the frame 11, as shown in FIG. 1(D). The insertion portion 1a is tapered in width and thickness directions. The fixture 1D further has a support portion 1c which stands vertically from the base end side of the insertion portion 1a, slightly tilts toward the glass plate, and further stands vertically. Therefore, in the fixture 1D of this embodiment, the insertion portion 1a is inserted between the sealing material 14 covering a part of the top portion of the frame 11 and the top portion, and the insertion portion 1a receives the edge of the heat insulating material 13. It also functions as the receiving portion 1b.

<Fifth embodiment>
As shown in FIGS. 2(A) to 2(E), the fixture 1E of the present embodiment is formed by stamping a flat plate made of metal (for example, stainless steel) by press working, and then bending it. It is composed by processing. That is, the fixture 1E is composed of an insertion portion 1a, a receiving portion 1b, supporting portions 1c and 1d, and an extending portion 1e.

The insertion portion 1a has two fork shapes. Each insertion portion 1a is bent downward from an inner end portion of an extension portion 1e extending flush from the receiving portion 1b toward the glass plate. That is, the adjacent insertion portions 1a are arranged with a space therebetween. In addition, although the insertion part 1a in this embodiment is two fork-shaped, you may set it to two or more according to the width|variety of 1 A of fixing tools.

As shown in FIG. 2D, each insertion portion 1a is set to have a width W smaller than the gap G between two adjacent ones. In this embodiment, as a relative relationship between the width W of the insertion portion 1a and the interval G, the interval G is set to exceed the width W of the insertion portion 1a. Note that the interval G is preferably twice or more. By setting the gap G and the width W in this manner, when inserting the insertion portion 1a between the glass plate 12 and the sealing material 14, the sealing material 14 is suppressed from being caught in the insertion of the insertion portion 1a. That is, the frictional resistance generated between each insertion portion 1a and the sealing material 14 during insertion is suppressed, and the pressure applied from the distal end side of the insertion portion 1a to the sealing material 14 is appropriately dispersed in the width direction of each insertion portion 1a, Due to these synergistic effects, entrainment of the sealing material 14 is suppressed.

In addition, the insertion portion 1a has an arc-shaped rounded tip in the width direction. Moreover, it extends from the distal end side toward the extension portion 1e with substantially the same width, and widens in the width direction from the front of the extension portion 1e toward the extension portion 1e. That is, the rounded tip suppresses damage to the glass plate 12 and the sealing material 14 . Further, the extending portion side of the insertion portion 1a enhances the strength of the insertion portion 1a and efficiently concentrates the pressure during insertion from the proximal end to the distal end. Accordingly, the insertion portion 1a is inserted between the glass plate 12 and the sealing material 14 without being bent during insertion.

Furthermore, the insertion portion 1a is slightly inclined toward the glass plate side. As shown in FIG. 2(E), the inclination angle α is preferably set within 95 degrees exceeding 90 degrees, and more preferably from 91 degrees to 93 degrees. By bending the insertion portion 1a to an angle within this range, when inserting the insertion portion 1a between the glass plate 12 and the sealing material 14 by pressing the tops of the support portions 1c and 1d with a finger or a tool, the rear A slight clearance is formed between the top of the side support 1 d and the glass plate 12 . Therefore, this clearance improves workability. In addition, since the insertion portion 1a is inserted in a state slightly inclined toward the glass plate side, it can be inserted more smoothly than when the insertion portion 1a is vertically pushed between the glass plate 12 and the sealing material 14. can.

The receiving portion 1b is a plane having the same depth as the thickness of the heat insulating material 13 or a depth slightly smaller.

The support portions 1c and 1d are a front support portion 1c located inside the room and a rear support portion 1d located on the glass plate side across the receiving portion 1b from the front and rear. As shown in FIG. 2(C), the front supporting portion 1c of this embodiment is a single plate having the same width as the extending portion 1e. Further, the width of the support portion 1c on the front side is set larger than the width of the insertion portion 1a. Note that the front support portion 1c is not limited to a single plate shape, and may be composed of a plurality of divided portions.

When the fixture 1E is viewed from the front, the rear support portion 1d is formed of a pair that sandwiches the front support portion 1c in the width direction, and is located outside the two insertion portions 1a in the width direction.

The top portions of the front support portion 1c and the rear support portion 1d are both bent to open outward so as to expand the opening beyond the depth of the bottom surface of the receiving portion 1b. As a result, the contact areas between the operator's fingers and the support portions 1c and 1d during insertion are enlarged, making it easier to push the fixture 1E. Further, when removing the fixture 1E, the bent portion functions as a hook for a finger or a tool, thereby facilitating the removal of the fixture 1E.

The height of the support portion 1c on the front side and the support portion 1d on the rear side is shorter than the length of the insertion portion 1a. The height is set so that it can be inserted into the portion 1b.

The extension portion 1e has the same width as the width of the front support portion 1c. Further, the extending portion 1e is set to have a depth that can avoid contact between at least the top portion of the support portion 1d on the rear side and the glass plate 12. As shown in FIG. The depth is appropriately set in consideration of the specifications of the glass plate 12 and the heat insulating material 13 so as to form a space serving as an air heat insulating layer between the glass plate 12 and the heat insulating material 13 .

According to the configuration of the fixture 1E, by making the insertion portion 1a two fork-shaped, compared to the insertion portions 1a of the holders 1A to 1D of the above-described first to fourth embodiments, , can be easily inserted between the glass plate 12 and the sealing material 14 . In particular, by setting the shape, position, angle, etc., of the insertion portion 1a, these synergistic effects suppress the entrainment of the sealing material 14 during insertion, suppress damage to the glass plate 12 and the sealing material 14, and improve work efficiency. will be improved.

Further, when the fixture 1E is viewed from the front, the pair of rear support portions 1d are arranged so as to sandwich the front support portion 1c in the width direction, and the width direction of each of the two insertion portions 1a. By arranging so as to be located on the outside, the heat insulating material 13 can be firmly supported. That is, since the heat insulating material 13 is supported at three points by the front supporting portion 1c and the pair of rear supporting portions 1d, the heat insulating material 13 can be firmly supported.

Furthermore, by providing the extended portion 1e, a space serving as an air heat insulating layer can be provided without providing a spacer between the glass plate 12 and the heat insulating material 13. FIG.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and design changes are possible within the scope of the claims. For example, it may be configured as follows.
(1) The support portion 1c of the fourth embodiment may be vertically erected without being bent in the same manner as in the first to third embodiments.
