Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an assembly structure of an inner frame member attached to an opening of a building, and more particularly, to a structure of a portion connecting side walls of the inner frame material.
[0002]
[Prior art]
For example, as a method of assembling a rectangular inner frame material as shown in FIG. 4, those disclosed in Japanese Utility Model Laid-Open Nos. 61-201480, 62-82686, and 64-33892 are disclosed. It has been known. Hereinafter, these will be referred to as a first conventional technique, a second conventional technique, and a third conventional technique, respectively.
[0003]
In each of the above-described conventional techniques, the end portions of the side plates having a plurality of ribs protruding from the outer surface are connected to each other to be assembled into a rectangular frame. In the first prior art, as shown in FIG. 5, the positions of the ribs 51 of the adjacent side plates 50 are aligned with each other, and the screws 52 are tightened using the thickened portions to connect the side plates 50. It has a structure. Such a tightening operation of the screw 52 is a laborious operation, which is disadvantageous in work efficiency. Moreover, in order to tighten the screw 52 to the end face of the side plate mouthpiece, a sufficient plate thickness is required. If the plate thickness is not sufficient, the strength may be insufficient, or the side plate may be cracked as the screw is tightened. .
[0004]
Further, the second prior art solves the problem of insufficient strength or cracking in the first prior art described above, and does not directly tighten the screw to the end face of the side plate, but instead of the corner fitting 60 as shown in FIG. The screw 62 (FIG. 7) is tightened into the side plate through the screw hole 61 using the. As shown in FIG. 7, the corner metal fitting 60 is fitted to the ribs 64 of both side plates in a state where the ribs 64 of the adjacent side plates 63 are aligned with each other. In this case as well, the tightening operation of the screw 62 is a laborious operation, which is disadvantageous in work efficiency.
[0005]
The third prior art is a further improvement of the second prior art, in which side plates are connected and fixed using only corner fittings without performing screw tightening work. FIG. 8 shows an enlarged cross section of the side plate 80, but groove-like recesses 82 are formed on both side surfaces of the rib 81. As the corner fitting, as shown in FIG. 9, a flat plate bent at a right angle is used. As shown in FIG. 10, the corner metal fitting 83 is fitted so that both side edges thereof are inserted into the concave portions 82 on the side surfaces of the adjacent ribs 81. The tooth portion 84 bites into the side surface of the rib 81 in the concave portion 82 to prevent the tooth portion 84 from coming off. In this inner frame material assembly structure, the side plates can be connected and fixed relatively firmly by simply inserting the corner fitting 83.
[0006]
[Problems to be solved by the invention]
All of the three conventional techniques described above are structures in which side plates having ribs are assembled into a frame, but the first conventional technique is insufficient in terms of work efficiency and side plate strength. The work efficiency is still insufficient. In contrast to the first and second conventional techniques, the third conventional technique solves problems in terms of work efficiency and side plate strength. However, the third prior art still has problems in the following points. If the width dimension of the corner metal 83 is at least the same as or slightly larger than the dimension between the adjacent ribs 81, 81 of the side plate 80, the tooth portion 84 does not bite into the side surface of the rib 81. However, since the side plate is manufactured by extrusion molding of resin, there is a limit to accurately forming the concave portion 82 on the side surface of the rib 81 into a shape corresponding to the width dimension of the corner fitting 83, and the corner portion in the concave portion 82 is Somewhat rounded. It is very difficult to insert the corner metal fitting 83 having such a shape as shown in FIG. Furthermore, when the corner fitting 83 is inserted between the adjacent ribs 81, 81, if the fitting 83 is not inserted straight but is inserted obliquely, the corner fitting 83 is stuck in the middle and cannot be pushed forward from there. Moreover, even if it tries to pull out in order to correct the slanted direction straight, the tooth portion 84 of the metal fitting cannot even bite into the side surface of the rib once in the recess 82 and pull out. Therefore, it is very difficult to insert the metal fitting and it may be impossible to insert the metal fitting, and even when it can be inserted, the metal fitting must be inserted carefully and accurately, and the speedy operation is obstructed.
[0007]
The present invention was devised to solve the technical problem in the third prior art, and the object thereof is to improve the work efficiency and the side plate when assembling the side plate having ribs using the corner connector. While solving the problem of strength, it is possible to easily insert the connector between the ribs even if the dimensional accuracy of the ribs of the side plate to be extruded is somewhat rough, and it is easy even if the connector enters diagonally between the ribs It is an object of the present invention to provide an assembly structure for an inner frame material of an opening of a building that can be accurately inserted with its orientation corrected.
[0008]
[Means for Solving the Problems]
In order to solve the above technical problem, the present invention has the following configuration. That is, in an assembly structure of an inner frame member that is assembled by abutting edges of two or more side plates to form an opening of a building and connecting the butted portions with a corner connector, the side plate is formed of the frame member. Providing a plurality of ribs projecting from the outer side surface and extending in parallel with the side of the opening, the corner connector comprises two insertion pieces inserted between the two adjacent ribs, The insertion piece has a notch and is bifurcated by the notch, and is configured to be elastically deformable so as to be bent inward in the width direction. And a protrusion that protrudes from the surface of the insertion piece and can be picked to bend the insertion piece inward.
[0009]
It is preferable that the insertion piece has a notch, and the notch is elastically deformed so as to be bent inward in the width direction.
[0010]
It is preferable that the insertion piece is bifurcated by a notch cut along the vertical direction, and the bifurcated insertion piece is elastically deformed to be bent inward in the width direction by the notch.
[0011]
Preferably, the tip of the bifurcated insertion piece is formed with a protruding portion that protrudes from the surface of the insertion piece and can be picked to bend the insertion piece inwardly.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The principal part of the side plate used in FIG. 1 in one Embodiment of the assembly structure of the opening inner frame material of the building which concerns on this invention is shown. FIG. 2 shows an example of a corner connector used together with the side plate of FIG. The side plate 10 is formed to have ribs 11 and 11 extending in the extrusion direction with a saddle-shaped cross-sectional shape as shown in the figure by extrusion molding of resin, and is cut into a predetermined length according to the size of the frame body. Four pieces are prepared. In addition, the protruding corner portions and the entering corner portions of the vertical ribs 11 and 11 are actually formed to be somewhat rounder than the right-angled corner shape as shown in the drawing. The four side plates 10 are assembled into an inner frame material in which end edges are butted in an orthogonal direction and the butted portions are coupled by a corner connector 12 to form a rectangular opening.
[0013]
The ribs 11, 11 formed so as to protrude from one surface of the side plate 10 are formed in an L-shaped cross section with the tips bent substantially at right angles as shown in the figure, and are arranged in such a manner that the bent tips face each other. ing.
[0014]
The corner connector 12 is inserted between the ribs 11, 11 and can be stretched on both sides so that the width dimension is at least equal to or slightly larger than the distance between the ribs 11, 11. As shown in FIG. 2, the flat plate material having the shape is bent at a substantially right angle along a bending line along the width direction, and is formed into two flat plate-like portions 16 and 16. Each plate-like portion 16 has a notch 13 at the center so that each of the plate-like portions 16 and 16 is bifurcated. Further, a turn 14 is formed at the tip of the branched bifurcated portion so that the operator can push it with a fingertip and bend it inward. On both side edges of the connector 12, teeth 15 similar to the teeth of the corner fitting in the third prior art described above are formed. In FIG. 1, a state in which one plate-like portion 16 of the corner connector 12 is inserted between the ribs 11 and 11 is partially represented by an imaginary line.
[0015]
FIG. 3 shows another example of the corner coupler. In this example, instead of the turn 14 in the connector of FIG. 2, an extended portion 17 is formed in which the tip of the bifurcated portion is made thinner and further extended forward. The operator can push the extension part 17 so that the fork part is bent inward by pinching the extension part 17 with a fingertip.
[0016]
The connector 12 configured as described above is formed by a notch 13 formed in the center when the connector 12 having a width slightly larger than the dimension is inserted between the ribs 11 and 11 shown in FIG. It can be inserted smoothly by elastic deformation in the direction of reducing the width dimension. Alternatively, even if the connecting tool 12 is pushed in at a slight angle with respect to the extending direction of the rib, the direction is easily corrected straight by bending the bifurcated portion, and can be smoothly inserted. Furthermore, even if it is changed in the middle while being slanted and cannot be pushed any further, when the turn 14 is picked and the tip of the bifurcated portion is sandwiched inward, the connector 12 is elastically deformed and its width dimension Therefore, the orientation of the connector 12 can be easily corrected and pushed further into the back. Of course, the inserted connector 12 is stretched to both sides to bite the respective tooth portions 15 into the side surfaces of the ribs 11 and 11, and the side plates 10 and 10 are connected and fixed securely and firmly.
[0017]
Of course, the connecting tool 12 can be smoothly inserted when assembled as described above, and the work is easy. However, the assembled frame body can be easily disassembled by inserting the turn 14 into the inside. Since the tool 12 can be extracted from between the ribs 11 and 11, it is easy. Even if the connecting tool 12 is pulled out without pinching the folded back 14 inside, the tooth portion 15 bites into the side surface of the rib 11 at that time to prevent it from coming off, and the connection and fixing of the side plates 10 are surely strong.
[0018]
The corner connector is not necessarily a metal fitting as described in the prior art, and can be made of, for example, a plastic material as long as it can be elastically deformed. Also, the notch need not have the shape shown in the figure. To make it easier to bend inward in the width direction, for example, a “drop-shaped” shape or a “flask-shaped” shape, the inner part The side part) may be cut out as much as possible. Furthermore, it is also possible to produce a flexible plastic material that is sufficiently elastically deformable without a notch and to have the same form as the corner fitting of the third prior art described above.
[0019]
In each of the above-described embodiments, four side plates are assembled into a rectangular shape for a typical rectangular window frame to form an inner frame material. For example, a shelf-like plate material is attached to a portion corresponding to the lower edge of the window. Alternatively, the three side plates may be assembled in a “U” shape and fitted into the upper edge and both side edges of the window. Alternatively, the two side plates may be assembled at approximately 90 ° and fitted into two sides of the triangular window. Moreover, the opening of a building is not limited to a through opening such as a window, and may be a recessed opening such as a pull-in shelf drawn into a wall from a wall surface.
