Description

  The present invention relates to a joinery for fixing a joinery frame to a building opening and fixing an angle provided on the indoor side of the joinery frame to a frame.

  In a joinery frame made of a conventional sash frame, an angle portion is generally fixed to a frame with screws. However, according to such a fixing structure with screws, fixing work with about 20 screws is required to fix one joinery frame to the building opening, which requires labor and time, and the head of the screw is There is a problem that it looks bad because it appears on the outside. In addition, since the fixing is performed with a large number of screws, there is a problem in that the angle may be wavy due to variations in construction.

  Various proposals have been made to solve such problems. In Patent Document 1, as shown in FIG. 9 (A), a bifurcated portion 51a at the upper part of an angle 51 is fitted on the outdoor side of the frame 50, covered with a resin cover 52 on the angle 51, and between the two A device in which a gap 53 is formed is proposed.

  In Patent Document 2, as shown in FIG. 9B, a frame attachment piece 61 is attached to an existing joinery frame 60, and a frame attachment auxiliary member 63 provided on the frame 62 is fitted to the frame attachment piece 61. There has been proposed one in which the anchor 65 welded to the frame 64 is also welded to the frame attachment auxiliary member 63 and the frame 62 is attached to the joinery frame 60.

  In Patent Document 3, as shown in FIG. 9C, a cover is covered with a cover 74 on the surface of an angle portion 72 that is fixed to a frame 70 with a screw 71 and the head of the screw 71 is hidden.

  Among the above-mentioned conventional joinery frames, the one described in Patent Document 1 has no means for restricting the movement of the angle 51 in the indoor / outdoor direction with respect to the frame 50, so the angle 51 and the frame 50 are indicated indoors and outdoors as indicated by an arrow X. If this is applied to a frame having a step portion 50a on the surface of the frame 50 as shown in the figure, a gap 54 may be formed between the step portion 50a and the cover 52, which may impair the design. Moreover, since the rising dimension from the frame 50 of the cover 52 is large, there is a possibility that the designability is impaired.

  Moreover, the thing of patent document 2 requires the frame attachment piece 61, the auxiliary member 63 for frame attachment, and the anchor 65, and also the number of parts increases and a manufacturing cost becomes high, and the man-hour of joinery frame construction increases, There is a problem that the construction cost becomes high.

  Moreover, although the head of the screw 71 is hidden by the cover 74 in the thing of patent document 3, since the screw 71 is used for fixing to the frame 70 of the angle part 72, labor and time are required for joinery frame construction. The problem of need is not solved.

  In view of the above problems, the present invention has an object to provide a joinery that can be fixed to an angle and a frame with a small number of parts, can be easily constructed in a short time, and has improved design. To do.

The fitting of claim 1 is:
Joinery frame fixedly provided in the building opening,
An angle having a substantially U-shaped portion that is configured to constitute an indoor side portion of the joinery frame and is fitted to an outdoor side of a frame provided in the building opening,
The substantially U-shaped part is made of an extruded product made of aluminum alloy, and is made of a first part located on the prospective surface side of the building opening, and an extruded shape made of synthetic resin, and the shoji mounting side of the first part is And a second portion that has a portion facing the first portion and sandwiches a frame with the first portion,
The first portion of the first portion facing the second portion protrudes toward the second portion and is engaged with a groove provided in the frame to restrict the movement of the frame in the indoor direction relative to the angle. for example Bei the engaging portion,
A step portion is formed by recessing the outdoor side of the frame surface, and the second portion is brought into contact with the recessed portion of the frame to form the surface of the second portion and the frame surface in the same plane. In addition, the indoor side end portion of the second portion is brought into contact with the stepped portion .

The joinery of claim 2 is the joinery of claim 1 ,
The engaging portion is formed of an elastic protrusion formed in a cut-and-raised shape.

The joinery of claim 3 is the joinery of claim 1 ,
The engaging portion is formed of a rising portion formed by extrusion molding.

According to the first aspect of the present invention, since the interior side of the angle is formed in a U-shape that fits the outside of the frame, movement in the joinery surface direction with respect to the angle of the frame is restricted. Further, the movement in the outdoor or indoor direction with respect to the angle of the frame is restricted by the engaging portion provided on the inner surface of the U-shaped portion of the angle. For this reason, the angle and the frame can be fixed to each other without using a screw. With this structure, the angle and the frame can be fixed with a small number of parts, and the fitting frame can be easily constructed in a short time, and the design can be improved.

  Further, since the groove to be engaged with the engaging portion provided at the angle is provided in the frame, the angle and the frame can be fixed to each other by pressing the frame into the U-shaped portion and fitting the engaging portion into the groove. Providing a groove in the frame is a simple process or molding and can be carried out relatively inexpensively.

Further, since the end portion on the indoor side of the angle is brought into contact with the step portion of the frame, the position of the frame on the outdoor side is regulated, and the engagement between the engagement portion of the U-shaped portion and the frame is combined. Bonding can be performed firmly and the angle surface and the frame surface are flush with each other, so that the design is improved.

According to the invention of claim 2 , since the engaging portion is formed by cutting and raising, it is possible to realize a structure in which the frame can be easily inserted into the U-shaped portion with respect to the angle and the frame is not easily removed from the angle. In addition, since the engaging portion is formed by cutting and raising, the engaging portion is elastically deformed when the frame is inserted into the angle without increasing the number of parts and partially raising and lowering. It is easy to fit into the U-shaped part of the frame. Further, the frame is pushed by the elasticity obtained by cutting and raising, and the prospective surface portion on the surface side of the angle is pressed against the surface of the frame, so that the design is improved.

According to the invention of claim 3 , since the rising portion formed by the extrusion molding is used as the engaging portion, the engaging portion can be formed in the extrusion molding process. For this reason, the separate process for processing an engaging part becomes unnecessary, and simplification of the number of processes is attained.
