The present invention will be explained in detail below using examples.

In the figure, reference numeral 1 denotes left and right stiles, and the stiles 1 are hollow inside by extrusion molding of synthetic resin.

On the opposing inner surfaces of the left and right vertical frames 1, there is provided a vertical groove 4 with an enormous groove 2 inside and an opening 3 interposed therebetween over the entire length of the upper and lower sides.

In the figure, reference numeral 6 denotes a handle frame, and the handle frame 6 has a substantially T-shaped cross section, and a handle portion 5 extends downward from the front and rear edges of the upper horizontal piece 11.

Extending from both left and right ends of the handle frame 6 are protruding arms 9 having a narrow neck portion 7 at the protruding base and a bulging portion 8 at the tip.

Two upper locking protrusions 12 are provided at the center of the upper surface of the upper horizontal piece 11 of the handle frame 6, and a successive recess 14 is provided at the lower end of the central vertical piece 13 of the handle frame 6. ■The inner side surfaces of the successful entry 14 serve as the front and rear lower locking protrusions 15, respectively.

Further, the bulging portion 8 at the tip of the protruding arm 9 has a sickle-like shape, and a cut groove 16 is provided at the tip.The cut groove 16 is provided to increase elastic force.

Therefore, the huge groove portion 2 of the vertical concave strip 4 of the opposing left and right stiles 1
The bulging portions 8 of the left and right protruding arms 9 of the handle frame 6 are fitted therein, and the handle frame 6 having the handle portion 5 is constructed between the center portions of the left and right vertical frames 1.

In this case, when the bulge 8 in the shape of a ridge is pushed through the opening 3 between the vertical grooves 4, the vertical stile 1 is hollow, so it easily deforms elastically, and the cut groove of the bulge 8 in the ridge shape 16, the bulging part 8 is elastically contracted, passes through the opening 3 of the intermediate part, and is inserted into the bulging groove part 2 and is fitted.

Here, in FIG. 1, the groove width of the enlarged groove 2 is l, the width of the opening 3 is h, the tip of the intermittent bulge 8 is h', and the middle of the rear end of the intermittent bulge 8 is l'. , if the width of the narrow neck portion 7 is H',
l <l',h>h',h÷H'.

Since h>h', the tip of the bulge 8 can be easily inserted into the opening 3, and by pushing the tip into the opening 3, the bulge 8 is contracted by the cut groove 16 and the bulge is closed. 8 into the huge groove 2, and at this time l<
1', the enlarged groove portion 2 expands outward and the enlarged portion 8 partially contracts, so that the enlarged portion 8 is firmly and elastically fitted into the enlarged groove portion 2.

With the handle frame 6 installed between the center portions of the left and right vertical frames 1 in this way, both ends of the facing material 10 such as glass (for example, inorganic glass, organic glass such as synthetic resin) are attached from above and below to the left and right sides. It is installed by fitting it into the vertical groove 4 of the vertical stile 1.

In this case, elastic packing material 17 is attached to the edge of the face material 10.
is the installation.

With the face materials 10 attached above and below in this manner, caps 18 which also serve as horizontal frames are attached between the upper and lower sides of the left and right vertical frames 1 using screws.

In this case, the cap 18 is provided with a horizontal groove 19 into which the upper or lower edge of the face material 10 is fitted.

Furthermore, handle covers 20 are attached to the front and rear outer peripheries of the handle frame 6.

An upper locking part 21 and a lower locking part 22 are provided on the upper and lower edges of the inner circumference of the handle cover 20, respectively, and the front handle cover 20 and the rear handle cover 20 are connected to the front of the handle frame 6, respectively. When inserted from the rear, the upper locking part 21 locks with the upper locking protrusion 12, the lower locking part 22 locks with the lower locking protrusion 15, and the front side of the handle frame 6 is locked. At this time, the edges of the panel 10 are pressed from the front and back using the stepped portions 23 provided on the backs of the front and rear handle covers 20 to cover the lower panel 10. It supports the upper edge and the lower edge of the upper panel 10.

Door A configured as described above is foldably connected to another door B that does not have a handle frame by a hinge body 24, and the other end of door B that does not have a handle frame is connected above and below to an upper rail 25 and below. The door A is rotatably hinged to each end of the rail 26, and a roller 27 is protruded above the other end of the door A that has the handle frame, and is slidably suspended from the upper rail 25. A so-called bifold door is constructed in which a guide shaft 28 projects below the other end and the lower rail 26 is slidable.

Here, the bifold door is opened and closed by operating the handle portion 5 of the handle frame 6 by hand.

In the above embodiment, an example of a bifold door is shown in which the other door B does not have a handle frame, but as shown in FIG. may be configured.

In the present invention, as described above, the protruding part of the handle frame is fitted into the large groove of the vertical groove of the left and right stiles, so the handle frame can be attached without the need for screws as in the conventional case. Moreover, since the vertical frame is hollow in the middle and made of synthetic resin, and the tip of the bulge is cut and grooved, elastic deformation of the vertical frame and , due to the elastic deformation of the bulge due to the presence of the cut groove, the bulge can be pushed through the opening of the intermediate part and elastically fit into the bulge groove, and as a result, a handle frame is formed at approximately the center of the vertical stile. When constructing the vertical stile, it can be attached simply by fitting the bulge from the side of the substantially central part of the vertical stile, making assembly easy.

Moreover, since this handle frame has a handle, there is no need to attach a separate handle to the frame, fewer parts are used, and workability is further improved. The structure can be simplified because the handle frame can be attached using the vertical grooves for attaching the face material.
Moreover, since the handle frame connects the center parts of the left and right vertical frames,
A roughly H-shaped temporary framework is created, and panels can be fitted from the top and bottom, improving ease of assembly.
