Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an entrance door, a partition door,
Concerning fittings such as window glass doors. The structure of this fitting is sometimes used for fences and the like.

[0002]

2. Description of the Related Art A structure in which a lattice bar is attached to a frame body formed by assembling frame materials to form a fitting is well known. 61-1
In the sliding door with a lattice of No. 15393, a notch is formed in the inner peripheral portion of the frame body, the end portion of the lattice bar is engaged with this notch, and then the lattice bar is brought into contact with the lattice bar along the inner periphery of the frame body. The pre-attached bead is mounted, the pre-attached bead places the edge of the glass on the (airtight material), the rear bead is placed on the edge of the glass, and the rim is attached to the rear bead. The crosspiece is pressed against the frame body to fix them all at once. That is, in this structure, the glass and the grid rail are fixed to the frame only after the glass is fitted and the ridge is attached.

However, in a fitting provided with glass, since the glass is conveyed without being attached in order to prevent the glass from being damaged during the conveyance, there is no connection between the frame and the lattice bar during the conveyance, and the lattice bar is not connected. There is a risk of rattling or coming off. Also, since the pre-beads are different in material from the frame and lattice bars, it is difficult to make them the same color and finish. There were many cases where the overall appearance of the fittings was different from what was originally imagined.

Therefore, it is necessary to caulk and connect the frame and the lattice rails or screw them together. If the number of the lattice rails is large, the machining is troublesome and the assembling work is very troublesome. Except when the difference in hue is obviously different,
I had no choice but to close my eyes. A mounting structure between the lattice rail and the frame body, which does not require caulking or screwing, has also been proposed (Fig. 7). That is, the lattice pressing packing c is attached to the other surface of the auxiliary eye plate b (fixture) having the bead a attached to one surface thereof, and the auxiliary eye plate b is fitted into the lattice frame f.
To the auxiliary eye plate b and the lattice frame f.
The lattice bars d and the lattice frame f are fixed by fitting them to the outer periphery of the grid frame d, the lattice frame f in which the lattice bars d are fitted is fitted to the inner periphery of the outer frame g, and the lattice frame f is removed by the wedge-shaped floor plate h. It is fixed to the frame g. However, this one requires the lattice frame f, the auxiliary eye plate b, the U-shaped metal fitting e, the floor plate h, etc. to fix the lattice bar d to the outer frame g, and the number of parts and the number of assembling steps are large. Workability is poor and costs increase.

Japanese Unexamined Patent Publication (Kokai) No. 6-50184 discloses a frame plate b having a concave portion a along the inner periphery thereof and a grid plate-shaped fixture e for fixing a lattice bar c arranged inside thereof. On one surface of the strip f extending along the inner circumference of the frame b, a pressing piece g that is brought into contact with the surface of the lattice bar c is provided near the inner circumference of the frame, and on the other side of the frame b near the outer circumference of the frame. A locking projection h that is snap-engaged with the one surface of the concave portion is formed, and a locking portion i that is engaged with the other surface of the concave portion of the frame body b on the other surface of the strip f near the outer periphery of the frame body has a spring portion j. It is disclosed that the engaging portion i and the strip f are urged in the direction of separating from each other by the elasticity of the spring portion j.

This is a fixture e without using a separate member.
Since the lattice bar c can be fixed to the frame body b only by
Since the number of parts is small, the manufacturing cost can be suppressed and the labor of assembling work can be reduced, but a space having a thickness enough to accommodate the spring portion j in the frame body b is required, and thus the frame body is required. Since the locking projection h that snap-engages with the locking portion i of the fixture e must be formed between the end of the lattice bar c inside b and the other surface of the recess, the frame b has a large size and a complicated structure. Will be things. Further, in order to reduce the thickness of the frame body b, the fixing tool e is formed in a band shape, and the leading bead m that comes into contact with the face material k is provided on the extension of the tip of the fixing tool e. Since it is exposed between the lattice bars c around k, the appearance is bad and it is difficult to match the hue with other portions. This is a common problem when attaching a supported member such as a face member or the like attached to the inside of the frame body to the frame body, not limited to the lattice door and not the lattice, to which the glass is attached.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fitting having a small number of parts, a simple structure, good workability of assembly, low manufacturing cost, and good appearance.

[0008]

A member to be supported is attached to a frame body to which a frame member is assembled by a fixture. In cross section, the frame member to which the end of the supported member is attached has at least an outer peripheral side wall, a front wall and an inner peripheral wall, and the inner peripheral wall has a notch through which the end of the supported member passes and the front wall and the inner peripheral wall are continuous. Then, an insertion space is formed on the back surface side. The fixture is located in the insertion space and extends in the longitudinal direction of the frame member, and the engaging portion is provided on one of the outer peripheral edge and the inner peripheral edge and the locking portion is provided on the other.

The end portion of the supported member is passed through the notch in the inner peripheral wall and positioned at the insertion portion. The engaging portion of the fixture is fitted into the engaging receiving portion formed on the frame member, and the engaging portion of the frame member is engaged with the engaging receiving portion of the frame member from the back surface side of the frame by rotation with the engaging portion as the fulcrum. . As a result, the front surface of the fixture presses the rear surface of the end of the supported member to mount the supported member on the frame.

In cross section, the frame member to which the end of the supported member is attached is provided with a back wall in addition to the outer peripheral side wall, the front wall, the inner peripheral wall, and the front wall and the inner peripheral wall are continuously inserted into the rear surface side in an L shape. A space may be formed and a face material mounting space may be formed between the back surface and the back wall of the fixture. An elastic pressing piece that presses the supported member may be attached to the front surface of the fixture. An airtight member may be attached to the back side surface of the fixture, with which the front side surface of the face member attached to the frame abuts.

[0011]

The fixture fixes the supported member to the frame. The configuration in which the fixing tool includes the engaging portion and the locking portion, and the frame member includes the engaging receiving portion and the locking receiving portion enables the fixing tool to be attached to the frame body without using other members. . The structure in which the elastic pressing piece that presses the supported member is mounted on the surface of the fixture prevents the rattling by pressing the supported member against the frame and absorbing the vibration. The face material mounting space facilitates formation of a fitting in which the face material is mounted. In this case, the airtight material provided on the back surface side of the fixture prevents rattling of the mounted face material.
