Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a lattice-integrated fitting that is easy to manufacture and has a good appearance, especially when the strength member is made of a metal material such as aluminum.

[Conventional technology and problems]

Lattice built-in fittings have been made of wood for a long time, but
Recently, metal materials such as aluminum have also been manufactured and put into practical use. The main points of the conventional lattice built-in structure will be explained with reference to FIG. A protruding fitting piece 11a is provided at the tip of the lattice member 11, and the fitting piece 11a of the lattice member 11 is provided on the fitting surface of the attachment 12 to which the lattice member 11 is directly attached.
A fitting hole 12a into which a is inserted is bored,
The fitting pieces 11a at both ends of the plurality of lattice members 11 are respectively fitted into the fitting holes 12a of the attachments 12 which are fixed to each other in the fixture, thereby forming a lattice.

However, in such conventional lattice-integrated fittings, the insertion holes 12a of the sticks 12 are bored on both sides of the sticks 12 in the width direction, leaving edges. It is difficult to manufacture it because it has to be accurately defined not only in the length direction but also in the width direction.If the size of the fitting hole 12a is increased to alleviate this difficulty, the installation state of the lattice member 11 will be unstable. cause Further, such a fitting hole 12a is usually formed by punching using a die and a punch, but after punching, the metal structure on the surface around the fitting hole 12a is destroyed, as shown in FIG. In addition, if the cross section of the attachment 12 is a hollow member surrounded on all four sides, the insertion hole 1 may be damaged in terms of die support.
The difficulty of drilling 2a in the correct position is further increased.

As a structure to eliminate these drawbacks, Jikosho
Publication No. 58-5027 discloses a decorative material having an opening cut out to a predetermined depth over the entire width of the insertion surface having the same width as the longitudinal decorative material, and in which a longitudinal decorative material is inserted into each opening. A plate made of glass or the like that is brought into contact with one support surface provided on the inner circumferential surface of two opposing sides of the strength member of the fittings, and the other surface of the decorative material (stick) A decorative structure for a frame body is disclosed in which a shaped body is held between mounting members made of an elastic material and protrudingly fitted between the other support surface of a strength member. However, in such a structure, even if the decorative material into which the longitudinal decorative material is inserted is manufactured during construction work, transported to the site, and fixed to the frame (strength member), the longitudinal decorative material will not move in the longitudinal direction of the decorative material. Since the decorative material can move freely in the direction perpendicular to the decorative material, the problem is that the longitudinal decorative material is displaced in the direction perpendicular to the longitudinal direction of the decorative material due to vibrations during transportation, which requires work to correct its position. In addition, one member that supports the decorative material into which the longitudinal decorative material is fitted is a mounting material made of an elastic material that is fitted and protruded between the plate-shaped body and the other supporting surface of the strength member. Therefore, if the longitudinal decoration material or plate-shaped body is strongly pushed toward the side where the attachment material made of elastic material is present, the longitudinal decoration material or plate-shaped body will easily come off from the strength member, and the role of the longitudinal decoration material as a lattice. Not only is it not possible to attach the longitudinal decorative material to the strength member, but it is necessary to separately prepare an elastic member called a new attachment material to be used at the site in order to fix the decorative material into which the longitudinal decorative material is inserted, which reduces workability. The problem was that it was also inferior.

In addition, Japanese Utility Model Application Publication No. 52-99396 discloses a box-shaped cross section with an opening on one side and a groove extending in the longitudinal direction, and a strip-shaped extending piece extending from the edge of the side wall below the groove to the opening surface of the groove. A notch cut out from the edge of the groove opening side to the inner surface of the wall perpendicular to the muntin mounting wall in the muntin mounting wall of a lattice frame (sticker) that overhangs and has a stepped portion formed on the opposite wall. A muntin (lattice member) having a hollow cross-section is inserted into this notch, and the tip of the muntin is supported by a pedestal formed by a stepped part protruding into the groove, and a side wall below the groove. Inside the cavity of the muntin (lattice member) is a tongue piece that is bent toward the inside of the groove between two rows of cuts formed from the edge to the proximal end of the band-shaped extension piece that extends from the edge to the groove opening surface. A structure is disclosed in which a muntin (lattice member) is inserted into a lattice frame (lattice member) and fixed thereto. However, in such a structure, the width of the lattice frame is not the same as the width of the muntins, so cutting tools such as saw blades cannot be used to form the notches in the lattice frame into which the muntins are inserted, and punches and dies are required. As a result, the metal structure on the surface is destroyed around the notch after punching, resulting in minute cracks, causing problems in appearance and corrosion resistance, and furthermore, the cross-sectional shape of the lattice frame is only on one side. Not only does it have to have a special groove shape with a lip (band-like extending piece), but it also has to have two rows of cuts at predetermined positions on the lip and be bent toward the inside of the groove to form tongue pieces. There were problems with Kumtin, such as the fact that there were many restrictions such as the cross-sectional shape of the muntin must be hollow.

[Means for solving problems]

The present invention solves each of the problems of the prior art described above, is easy to manufacture from metal materials, has a good appearance, and can be manufactured in a factory and transported to the site to form a frame (strength member).
This relates to a fitting with a built-in lattice, in which the lattice member does not move relative to the attachments even if there is vibration during transportation, and the lattice can be firmly fixed because no elastic members are used. In this case, an attachment having an opening cut out to a predetermined depth over the entire width of the insertion surface having the same width as the lattice member is provided on the attachment fitted into the inner peripheral surface of at least two sides of the strength member of the fitting. The lattice member is fitted into and fixed in an opening having the same width as the lattice member, and the lattice member is fitted into each of the openings provided in the stick.

Hereinafter, the present invention will be explained in detail with reference to the drawings.
Fig. 1 is a front view of one embodiment of the lattice-integrated fittings according to the present invention, Fig. 2 is an enlarged cross-sectional view taken along the line A-A in Fig. 1, and Fig. 3 is a cross-sectional view taken along the line B-B in Fig. 1. 4A and 4B are perspective views showing a part of an example of a grid member, and FIGS. 5A and 5B are perspective views showing a part of an example of a lattice member used in the present invention, Figure 6 A,
B and C are respectively perspective views showing examples of attachments into which the attachments are inserted, and FIG. 7 shows a state in which the attachments shown in FIG. 5A are fitted into the strength member via the attachments shown in FIG. 6B. Fig. 8 is a perspective view showing the two directions of the vertical and horizontal frames, and the attachment is fitted with a lattice member assembled perpendicularly and orthogonally to each other, and this attachment is used to reinforce the vertical and horizontal frames. It is an explanatory view of a state before it is assembled into a member.

In the drawings, reference numeral 1 denotes a lattice member having a width w and a thickness t, and may be a solid body as shown in FIG. 4A, or a hollow body as shown in FIG. 4B. Reference numeral 2 denotes an attachment to which the lattice member 1 is directly attached by fitting, and has the same width as the lattice member 1 provided on an attachment 4 that is fitted into the inner circumferential surface of a strength member 3 such as a frame material of a fitting, as described later. It is fitted into the opening of the frame and fixed, and is therefore fixed in the same direction along the frame material etc. This retainer 2 has a height h and has a U-shaped cross section as shown in FIG. 5A, or may be a hollow body as shown in FIG. 5B. The insertion surface 2a of the stick 2 has the same width as the width w of the lattice member 1, and an opening 2b cut out by a predetermined depth d is formed over its entire width. Since the opening 2b formed on the insertion surface 2a of this attachment 2 is into which the lattice member 1 is inserted as described later, when the direction of the lattice is perpendicular to the strength member 3 such as the frame material of the fittings, As shown in FIG. 5A, the depth direction of the opening 2b is perpendicular to the insertion surface 2a,
The cutting width of the opening 2b (hereinafter simply referred to as cutting width) parallel to the length direction of the stick 2 is the same as the thickness t of the lattice member 1. In addition, the direction of the lattice is oblique to the strength member 3 such as the frame material of the fittings (the angle made with the direction perpendicular to the frame material, and therefore the angle made with the direction perpendicular to the insertion surface 2a of the stick 2 is θ) ), the fifth
As shown in Figure 5B, the depth direction of the opening 2b is diagonal at the same angle with respect to the insertion surface 2a, and the cutting width of the opening 2b (indicated by t' in Figure 5B) corresponds to the degree of the diagonal direction. is larger than the thickness of the grid member (t′=
tsecθ) It's getting better. Such attachments 2 are fitted into the inner circumferential surfaces of at least two sides of the strength members 3 of the fittings, for example, the vertical stile 3a, the upper stile 3b, the lower stile 3c, and the middle stile 3d, as shown in FIGS. 2 and 3. They are fixed in the same direction along the strength member 3. The attachment 2 is fitted into the inner circumferential surface of the strength member 3 by being inserted into the attachment 4, and the attachment 4 is inserted into the strength member 3 (in FIG. 2, the upper frame 3b and the middle frame 3d, the middle frame 3d and the lower frame 3c, and in Figure 3, stile 3a and stile 3
This is done by fitting into the inner circumferential surface of a).
This attachment 4 has a U-shaped cross section as shown in FIG. A lip portion 4a is provided on the same extension surface as the opening surface from one or both end edges of the portion. It is preferable that the attachment 4 and the strength member 3 are provided with slight protrusions here and there to prevent rattling when the attachment 4 into which the retainer 2 is fitted is inserted into the strength member 3. When the attachment 2 is inserted into the attachment 4 in this way, the side wall side of the opening 2b of the attachment 2 is completely shielded by the attachment 4 and opens only on the insertion surface 2a. The fitted lattice member 1 is in a state in which it cannot move either in the longitudinal direction of the attachment 2 or in a direction orthogonal to the longitudinal direction.

The lattice member 2 may be installed in one direction or intersect in two directions, and in any of the above cases, the lattice member 2 is not necessarily installed in a direction perpendicular to the strength member 3 of the fittings, but may be in an oblique direction. Also good. Therefore, the attachment 4 into which the retainer 2 is fitted and fixed needs to be fitted into at least two sides of the strength member 3, and the strength member 3 on those two sides
do not necessarily have to be opposite to each other, but may be two adjacent sides depending on the design of the checkered pattern. Further, the external shape of the fitting and the shape of the structure constituted by the strength member 3 constituting the external shape may be, for example, a pentagon other than a right angled quadrilateral.

[Method for making tsuko and assembling fittings]

The attachment 2 is manufactured by using a saw blade with the same thickness as the thickness t of the lattice member 1, regardless of whether the material has a U-shaped cross section as shown in Figure 5A or a square shape as shown in Figure 5B. The opening 2b can be easily formed by sawing. The other members can be manufactured by conventional methods. To assemble the lattice-incorporated fittings from the members manufactured in this manner, for example, the following procedure is performed. As shown in FIG. 8, the lattice member 1 arranged in a predetermined direction is fitted into the opening 2b of the attachment 2,
After fitting this stick 2 into the attachment 4, move the strength member 3 closer to the direction of the attachment 4 and push it further.
are fitted into the strength members 3, and necessary connections and fixings are performed including the lattice members 1 in each direction and other members to assemble the fittings.

[Action and effect]

The lattice built-in fittings according to the present invention do not provide protruding fitting pieces at the ends of the lattice member and use the ends as they are for fitting, so there is no need to process the ends of the lattice member.
In addition, since the opening of the lattice member into which the lattice member is inserted is formed over the entire width of the lattice member, in order to make the position accurate, it is only necessary to define the opening in the length direction of the lattice member. It is easy to make the position accurate, and this processing method does not involve destroying the surface metal structure and creating minute cracks around the positioned area, such as by punching an inset hole using a punch and die. Since a sawing method using a blade can be adopted, there are no problems with appearance and corrosion resistance, and the opening can be easily processed.
Furthermore, both side walls of the side of the attachment into which the lattice member is inserted are completely shielded by the attachment, so the attachment into which the lattice member is inserted is manufactured in a factory and delivered to the site with the attachment inserted into the attachment. When fixing the grid to a strength member, the grid member will not shift in the direction perpendicular to the longitudinal direction of the grid member due to vibrations during transportation, so there is no need to correct the position. There are also no members that make the fixation of the grid uncertain.
