[Prior Art] A steel fitting provided inside a building is generally of an assembled type. Therefore, the horizontal frame and the vertical frame of the hanging type sliding door and the like are coupled and assembled by the coupling device.

A conventional coupling device will be described with reference to FIGS. 6 to 9.

In the figure, 1 indicates a horizontal frame and 2 indicates a vertical frame.

As shown in the cross section of FIG. 6, the lateral frame 1 is formed by combining an outer surface material 3, a back surface material 4, a door pocket panel holding material 5, and a rail support material 6. The rail 7 is attached to the rail support member 6,
A sliding door 10 is slidably suspended on the rail 7 via wheels 8 and a bracket 9.

An upward hook 11 is provided on the upper surface edge of the outer surface member 3,
An eaves portion 13 is provided at one end edge of the back surface material 4 below the upward hook portion 11.

Strip-shaped brackets 14 are attached at a required pitch so as to be suspended on the eaves portion 13.

At the upper end of the cover 15 that covers the front surface of the horizontal frame 1, a downward hook is provided.
16 is formed, and the cover 15 is attached by engaging the downward hook portion 16 with the upward hook portion 11 and then fixing the lower end to the bracket 14 with a screw.

In addition, a strike 17 is attached to one end of the horizontal frame 1 so that a hook bar for locking the sliding door 10 can be fitted therein.

At both ends of the horizontal frame 1, connecting fittings 18 having a U-shaped cross section are fixed. A concave portion 19 is formed on a surface of the vertical frame 2 facing the horizontal frame 1. The concave portion 19 at the upper end of the vertical frame is fitted with the connecting fitting 18, and is fixed by a bolt from the vertical frame 2 side. The horizontal frame 1 and the vertical frame 2 are coupled and connected.

[Problems to be Solved by the Invention] In the above-described conventional coupling device, the connecting fitting 18, the cover mounting bracket 14, and the locking strike 17 are individually mounted, so that the number of parts is large, Further, there is no mechanism for vertically aligning the horizontal frame 1 and the vertical frame 2, and the vertical alignment is performed by adjusting the horizontal frame 1 and the vertical frame 2 when tightening them with bolts. Was a hassle.

In view of such circumstances, the present invention aims to provide a coupling device for an upper horizontal frame and a vertical frame, which has a small number of parts and is easy to assemble.

[Means for Solving the Problem] According to the present invention, a male coupling fitting having a convex portion projecting toward the vertical frame at the end of the horizontal frame main body and having notches formed at the upper end and the lower end is fixed, Female coupling fittings whose upper and lower ends are horizontally bent are fixed to the ends of the vertical groove main body in which the vertical groove is formed, and the convex portion can be fitted into the concave groove. At the same time, the upper and lower ends of the female fitting can be inserted into the upper and lower cutouts of the male fitting, respectively, so that both can be joined with the male fitting and the female fitting engaged with each other. It is a feature.

[Operation] The convex part of the male fitting is fitted in the groove of the vertical frame body, the upper and lower ends of the female fitting are inserted into the notches of the male fitting, and the horizontal frame body and the vertical frame body are horizontal. Direction, vertical positioning. Thus, if the male fitting and the female fitting are joined together, the horizontal frame and the vertical frame are aligned and joined together.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

Note that, in FIGS. 1 to 5, the sliding doors, rails, rail supporting portions, and the like are omitted.

An upward hook 22 is formed at the lower end of the front surface of a horizontal frame body 21 having a substantially inverted L-shaped cross section in which a part of the lower surface portion and the front surface portion are omitted.
The upper end of the L-shaped front cover 23 is folded back into a V shape,
The upper end of the front cover 23 can be engaged with the upward hook 22.

A concave groove 29 of a vertical frame body 27 in which male coupling fittings 25 are fixed to both ends of the horizontal frame body 21 and a concave groove 26 is formed over the entire vertical length.
A female fitting 28 is fixed to the upper end of the.

As shown in FIG. 2, the male coupling member 25 has a convex portion 30 extending in the vertical direction in the center and fitted in the concave groove 26, and notches 31 and 31 formed at the upper end and the lower end, respectively. Further, the male coupling fitting 29 has leg portions 32 extending in the axial center direction of the horizontal frame main body 21 at four positions on the upper, lower, left and right sides, and the leg portions 32 are magnet attractors.
33 is installed.

As shown in FIG. 2, the female fitting 28 has a U-shape in which an upper end portion 34 and a lower end portion 35 are horizontally bent, and the upper end portion 34 and the lower end portion 35 are inserted into the notches 31 and 31, respectively. It is supposed to be.
Further, a strike plate 36 having a hole 37 into which a lock bar of a sliding door is fitted and removed is fixed to the lower end portion 35.

A screw hole 38 is provided in the convex portion 30 of the male coupling member 29, and a play hole 39 for inserting a bolt is formed in a vertical portion of the female coupling member 29.

The horizontal frame 1 and the vertical frame 2 are assembled by fitting the convex portion 30 into the concave groove 26 with the upper end portion 34 and the lower end portion 35 of the female metal fitting 28 being inserted into the notches 31 and 31, and then the vertical frame 2 is reversed. Bolt 40 from the horizontal frame side Vertical frame body 2
7. The play hole 39 is penetrated and screwed into the screw hole 38.

At this time, the horizontal alignment of the horizontal frame 1 and the vertical frame 2 should be such that
The fitting of the groove 30 with the groove 30 allows vertical alignment by inserting the upper end 34 and the lower end 35 into the upper and lower cutouts 31, 31, respectively.

Next, the front cover 23 can be easily assembled by hooking the upper end of the cover 23 to the upward hook 22 and adhering the lower end to the magnet adsorber 33.

Needless to say, the shapes of the male fitting and the female fitting can be changed in various ways, such as by integrally molding the female fitting and the strike plate.

[Effects of the Invention] As described above, according to the present invention, the following excellent effects are exhibited.

(I) Since the horizontal frame and the vertical frame can be assembled by aligning the male coupling fitting and the female coupling fitting, it is possible to easily assemble them by simply screwing the bolts.

(Ii) Since the coupling fittings can be manufactured symmetrically with each other, it is possible to use common parts for the left and right coupling devices.

(Iii) Since the magnet adsorber for adsorbing the front cover is attached to the male coupling fitting, a metal fitting for attaching the magnet adsorber is not required.

(Iv) Since the strike to and from which the hook for the sliding door lock is fitted is attached to the female coupling fitting, a separate fitting for the strike is not required.
