Description

  The present invention relates to a sash door structure in which a joining tool is inserted in a hollow corner portion of a hollow vertical gutter and a horizontal gutter and the gutters are joined to each other.

  Conventionally, Patent Document 1 discloses a sash door structure in which a joining tool is inserted into a hollow corner portion of a vertical sash and a horizontal ridge of a sash to join the heels together. In this technique, two sash frame members having square hollow cross-sections whose ends are cut in a 45-degree direction are arranged at right angles to each other, and two substantially L-shaped corner blocks each composed of two arms facing at right angles to each other. Are inserted into the hollow cross section of the sash frame member to bring the cut surface of the sash frame member into close contact with each other and have a spring action that presses against the inner wall within the hollow cross section of the sash frame member It is characterized by attaching an attachment plate.

By the way, the above technique requires the attachment plate to be pressed by a spring action, so that it takes a lot of force to assemble, and it also causes rattling due to a decrease in the pressing force due to long-term use, requiring disassembly, parts replacement, and reassembly. There was a problem. Moreover, since the thickness of the sash in the depth direction is necessary for the attachment plate to have a spring action, there is a problem that the cross-sectional shape of the sash is restricted.
JP 2003-301670 A

  The problem to be solved by the present invention is to solve these conventional problems, and can easily and firmly join without any force at the time of assembling the heel, and can be molded into a free cross-sectional shape and has no backlash. It is to provide a door structure.

The configuration of the present invention that solves this problem is as follows.
1) In a sash door structure in which a joint is inserted into a hollow corner portion where a hollow vertical shaft and a horizontal shaft are abutted at right angles, and the flanges are joined to each other, screw holes into which the joint is threaded are inserted into each flange. A substantially L-shaped plate formed at each position, each having a groove for inserting the plate end of the connector on the opposite hollow inner wall of each ridge, and a screw screwed to the connector in a state of being inserted into the groove Screw holes that communicate with the holes are formed in each ridge, and the right-angled part that becomes the corner corner of the joint is cut out in a semicircular shape so that the misalignment of the butt portion of each ridge can be absorbed and inserted into the groove . A sash door structure characterized in that the joints are screwed through the screw holes of each collar so that the collars can be joined together without backlash. 2) The plate thickness of the threaded hole of each collar is increased. In the sash door structure described in 1), the strength of which is increased.

  According to the present invention, since the connector inserted in the groove of each rod is fixed by screwing the screw into the threaded screw hole of the connector from the outside of each rod, it is extremely easy and strong without requiring force. Can be joined without gaps, and there is no backlash. Even if looseness occurs due to loosening after a long period of use, the initial strong joint can be easily recovered by retightening the screws without disassembling or replacing parts. Moreover, since the connector is plate-shaped, each hook can be molded into an arbitrary cross-sectional shape, and the degree of freedom in design is high. Furthermore, in a hinged door pivoted with a sliding door or a butterfly-type screw, a sash door can be constructed that allows the sliding roller or slide rail to be easily embedded at the end of a thin dividing member, and that can be opened and closed more smoothly. .

In the present invention, the plate thickness of the screw hole portion of each flange is increased to improve the strength and secure the space for mounting the countersunk screw . Embodiments of the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is an explanatory view of a sash door of the embodiment, FIG. 2 is a cross-sectional view showing the joining of the scissors of the embodiment, FIG. 3 is a cross-sectional view taken along the line AA of FIG. is there. In the figure, 1 is a vertical gutter, 1a is a hollow part, 1b is a fastening part, 1c is a groove, 1d is a thick part, 1e is a screw hole, 1f is a glass groove, 2 is a horizontal gutter, 2a is a hollow part, 2b , 2c is a groove, 2e is a screw hole, 3 is a connector, 3a is a plate end, 3b is a screw hole, 3c is a notch, 4 is a countersunk screw, 5 is glass, and 6 is a covering member.

  The vertical rod 1 of this embodiment is made of an extruded aluminum alloy having a hollow portion 1a as shown in FIGS. 1 to 3, and the end portion is cut at a 45 degree angle to form a fastening portion 1b. Grooves 1c for inserting the plate ends 3a of the connector 3 are formed along the longitudinal direction on the opposite short hollow inner walls, and a thick portion 1d is formed at the center in the width direction to form a screw hole of the connector 3 A conical screw hole 1e communicating with 3b is opened, and a glass groove 1f into which the glass 5 is inserted is formed on one side surface. The reed 2 also has the same configuration.

  As shown in FIG. 4, the connector 3 is a thin metal plate having a substantially L shape as a whole, and plate ends 3a having thicknesses that can be inserted into the grooves 1c and 2c of the vertical rod 1 and the horizontal rod 2 at both ends. The formed screw holes 3b that are formed and communicated with the screw holes 1e, 2e of the vertical rod 1 and the horizontal rod 2 are respectively formed symmetrically, and semicircular cutouts are formed in the right and left corner portions that are the corner corners. 3c is formed.

  One plate end 3a of the connector 3 is slid from the fastening portion 1b of the vertical rod 1 in the groove 1c and inserted into the hollow portion 1a, and the other plate end 3a of the connector 3 is fixed to the horizontal rod 2 It slides in the groove 2c from the processed portion 2b and inserts it into the hollow portion 2a, butts the fastening processing portions 1b, 2b of the vertical rod 1 and the horizontal rod 2 with each other, and the countersunk screws 4 of the vertical rod 1 and the horizontal rod 2 The screw holes 1e and 2e are screwed into the screw holes 3b of the connector 3, and the connector 3 is sandwiched between the outer surfaces of the vertical rod 1 and the horizontal rod 2 and the grooves 1c and 2c by the countersunk screws 4, so Is firmly fixed. Thereafter, in parallel with the insertion of the glass 5, the four sides are framed by the above-described joining method, and the L-shaped covering member 6 is fitted to the corner portion where each butt is abutted to assemble the sash door.

  Since the present embodiment is configured as described above, it can be joined very easily and firmly without a gap without requiring force, and there is no backlash. Moreover, since the connector 3 is plate-shaped, it became a sash door excellent in design, such as being able to mold a ridge into a thin cross-sectional shape as shown in FIG.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a sash door attached to an opening of a house or the like, as well as a frame configured with a hollow cage as a frame.

It is explanatory drawing of the sash door of an Example. It is sectional drawing which shows joining of the collar of an Example. It is AA sectional drawing of FIG. It is a top view of the connector of an Example.
