DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joining structure of a frame member formed by joining frame members such as a window frame and an opening frame.

[0002]

2. Description of the Related Art Conventionally, when assembling a frame material such as a window frame or an opening frame, a wood screw is applied from the outer surface of one frame to the opening of the other frame with the ends of the vertical frame and the horizontal frame abutted. It was common to drive in and fix it, assemble it as a four-sided or three-sided frame, install it at a predetermined position, and fix it to a frame such as a pillar, stud or lintel.

[0003]

However, according to such prior art, the wood screws must be driven in while hand-holding the ends of the vertical frame and the horizontal frame in a state where the ends of the vertical and horizontal frames abut each other. It is easy to move in an unstable state, it is difficult to work, and there is a possibility that misalignment, gaps and misalignment may occur in the butted portion.

Further, since a wood screw is driven into a wood opening, cracks and bulges are likely to occur in the frame material. To prevent this, it is necessary to first drill a guide hole and then drive the wood screw.
There is a problem that the work is troublesome and takes a long time.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention solves the above-mentioned problems in the prior art, and provides a novel frame material joining structure which is simple in framing work and does not cause misalignment or gaps in abutting portions. The purpose is to:

The joining metal fitting has a pair of arms via corners, and has a contact portion bent at an acute angle at the end of each arm. It is characterized in that the joining fitting is locked to the frame material in a state in which the contact portion is fitted to the width direction groove of each frame material along the outer surface of the material.

According to a second aspect of the present invention, in the joint structure for a frame member according to the first aspect, a groove depth substantially equal to or greater than the thickness of the joint fitting is provided in a portion extending from the butt end of the frame members to the widthwise groove. A longitudinal groove having the following shape is formed, and the arm portion of the joining fitting is fitted into the longitudinal groove.

According to a third aspect of the present invention, in the joining structure of the frame members according to the first or second aspect, an outwardly bent enlarged portion is formed at the end of the contact portion of the joining fitting, and the distal end of the enlarged portion is formed. Are formed in an arc shape.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. Frame materials generally used as the vertical frame 1 and the horizontal frame 2 are made of solid wood, plywood, wood fiber board, Glued lumber, veneer laminated wood, etc. are used alone or in any combination as a base material.At least the parts that are visible when used as a frame material and constructed on a skeleton are cut from natural wood. Natural veneer, artificial veneer,
These nonwoven fabric on the back, paper, synthetic resin sheet, veneer backed the backing of the glass sheet such as a sheet, decorative paper or decorative sheet, such as a decorative synthetic resin sheet is adhered,
Alternatively, surface painting is performed by performing colored painting. A coating or overcoat layer may be further provided on these surfaces.

In the case of a frame in which a casing is mounted on a side surface at the time of construction, a casing groove into which the casing is fitted can be engraved on the side surface.

As shown in FIGS. 1 to 3, the vertical frame 1 and the horizontal frame 2 are joined by cutting the ends of these frame materials obliquely at an angle of 45 degrees and abutting the frame materials. Alternatively, as shown in FIGS. 4 and 5, a striking connection (toning) may be used in which the inner edge of one frame member is brought into contact with the opening of the other frame member.

On the outer surface of the frame material, width direction grooves 3 and 4 are formed at points spaced a predetermined distance from the abutting end. The distance between the point where the width direction grooves 3 and 4 are formed and the butt end is determined by the angle 5a of the joint fitting 5 to be described later and the contact parts 5b and 5b.
It corresponds to the length of the arm portions 5c, 5c up to the base of b.

The width grooves 3 and 4 are formed so as to extend in a direction perpendicular to the longitudinal direction of the frame material. Width direction groove 3,
The extension length of 4 is at least equivalent to the width of the joint 5, but may be extended to be wider than the width of the joint 5.
Further, as shown in FIG. 1, the frame members 1 and 2 may be formed over the entire width, and may be arbitrarily determined so as not to affect the strength of the frame members or the appearance after the frame members are constructed.

As shown in FIG. 2, the widthwise grooves 3 and 4 are formed as inclined surfaces 3a and 4a in which the side surfaces of the grooves at the frame material abutting ends gradually approach the ends toward the groove bottoms. The contact parts 5b, 5 of the joint fitting 5 against the inclined surfaces 3a, 4a
The joining fitting 5 is fixed by the engagement of b.

The inner angle θ (FIG. 2) formed between the inclined surfaces 3a and 4a of the width direction grooves 3 and 4 and the outer surfaces of the frame members 1 and 2 is preferably about 30 to 70 degrees, and most preferably about 60 degrees. If the internal angle θ is less than 30 degrees, the portion constituting the internal angle becomes too thin and the strength is insufficient, and the portion is liable to break when joined with the joint fitting 5, while the internal angle θ exceeds 70 degrees. And the angle of engagement between the contact portions 5b, 5b of the joint fitting 5 is too small, so that the joint fitting 5 is easily detached from the frame members 1, 2.

On the outer surfaces of the frame members 1 and 2, longitudinal grooves 6 and 7 can be formed substantially the same as or deeper than the thickness of the joint fitting 5. When the cleave of one of the frame members (the cleave of the horizontal frame 2 in FIG. 5) is exposed at the time of joining by the splicing, the longitudinal groove 7 is formed from the outer surface to the cleaver of the frame member 2, and the longitudinal groove 7 is formed. The direction groove 7 may communicate with the longitudinal groove 6 formed on the outer surface of the other frame member (vertical frame 1). By forming the longitudinal grooves 6 and 7 in this manner, when the joining fitting 5 is locked to the frame materials 1 and 2, it is accommodated in the longitudinal grooves 6 and 7 so as not to protrude from the surface of the frame material. be able to.

The width of the longitudinal grooves 6 and 7 is preferably formed to be substantially the same as the width of the joint fitting 5. Thereby, when the joint 5 is locked to the frame members 1 and 2, the arms 5 c and 5 c of the joint 5 are fitted into the longitudinal grooves 6 and 7, and the vertical frame 1
And the horizontal frame 2 can be prevented from being relatively displaced in the front-rear direction (vertical direction in FIG. 2, FIG. 3, and FIG. 5) (misalignment).

The longitudinal grooves 6 and 7 are formed at least from the abutting ends of the frame members to at least the arm portions 5c and
5c is formed so as to extend by substantially the same length as that of FIG. 5c, but may be formed to be longer, for example, to extend over the entire length of the frame material (FIGS. 1 to 5). 3).

The fittings 5 are locked by fitting the contact portions 5b, 5b into the widthwise grooves 3, 4 of the vertical frame 1, the horizontal frame 2, and join the vertical frame 1 and the horizontal frame 2. And is made of elastic plate-like steel, a synthetic resin molded body, or the like.

As is apparent from FIG. 2, the joining fitting 5 has arms 5c, 5c via corners 5a, and has abutting parts 5b, 5b bent at the tip thereof at an acute angle. And an expanded portion 5 bent outward at the tip thereof.
d, 5d. The corner 5a is preferably formed in an arc shape in order to avoid interference with the corner where the frame members 1 and 2 are abutted.

As described above, the arm portions 5c have the same length as the distance from the butted ends of the frame members 1 and 2 to the width grooves 3 and 4, and the arm portions 5c and 5c have the same length.
The angle between them is formed to be substantially the same as or slightly less than 90 degrees, which is the angle formed by the outer surfaces of the butted frame members 1 and 2. By forming the joint at an angle smaller than 90 degrees, the joint 5 is locked in a state of being expanded by the frame material through the elasticity of the material, so that the joint 5 attempts to return to the original angle. Using the force, the frame members 1 and 2 can be more strongly joined.

The arms 5c and 5c have the same length, and it is general that the entire joint 5 is symmetrical about the corner 5a. Needless to say, when the distances from the butted ends to the widthwise grooves 3 and 4 are different, the arm portions 5b and 5b also have different lengths accordingly.

As described above, the abutment portions 5b, 5b formed at the tips of the arm portions 5c, 5c are formed such that the inner angle between the arm portion and the abutment portion is the inclined surface of the width direction grooves 3, 4 of the frame material. 3a, 4a
Is formed so as to be substantially the same as or slightly smaller than the internal angle θ formed by the outer surface of the frame member. The inner angle between the arm portions 5c, 5c and the contact portions 5b, 5b is θ
Even if it is smaller, it can be deformed by the elasticity of the material of the joint fitting 5, so that the contact portions 5b, 5b
Is easy to fit into the width direction grooves 3 and 4 of the frame material.

If necessary, expanded portions 5d, 5d which are bent outward can be formed at the tips of the contact portions 5b, 5b. The distal ends of the expanding portions 5d may be formed in an arc shape. By forming such expanded portions 5d, the fitting work of the contact portions 5b, 5b with the width direction grooves 3, 4 can be performed more easily.

In the actual framing work, first, one contact portion 5b of the joining fitting 5 is fitted into the widthwise groove 3 or 4 of either the vertical frame 1 or the horizontal frame 2, and then the vertical frame 1 With the ends of the horizontal frame 2 butted against each other, the joining fitting 5
The other contact portion 5b of the other frame member in the width direction groove 4 or 3
To fit. Thereby, whether it is a fastening connection (FIGS. 1 to 3) or a driving connection (FIGS. 4 to 5),
The frame members 1 and 2 can be easily and firmly joined to each other by using the joint fitting 5, and this operation can be repeated to assemble a three-way frame or a four-way frame. Alternatively, these width direction grooves 3 are
4 may be assembled by fitting the contact parts 5b, 5b of the joint fitting. The three-sided or four-sided frame joined in this manner is fitted into a predetermined position, fixed to a frame, and constructed.

[0026]

According to the present invention, the joining structure of the frame material can be obtained by fitting the joining metal fitting into the widthwise groove previously formed in the frame material. Misalignment and gaps do not occur due to misalignment.

In particular, in the case of joining by joining, the joining members are fitted into the grooves in the width direction of the two frame members so that the frame members are brought into contact with each other by utilizing the elasticity of the joining members themselves and are pulled toward the corner. Force can be applied, and a good finish with no slippage can be obtained.

In addition, since the framing work can be completed by one-touch operation using a joining metal fitting without using a wood screw when joining the frame members, the work is easy and the working time can be shortened.
