Description

[Detailed description of the invention] This invention relates to the improvement of horizontal frames used for fitting frames such as various door frames, window frames, and partition frames.

Traditionally, horizontal frames used for this type of fittings frames, such as upper frames, blinds, and baseboards, have a pair of rails and have a complex cross-sectional shape, so they are generally drawn from aluminum alloy. Therefore, sufficient strength could not be expected and manufacturing costs tended to be high.

In addition, using steel plates, the horizontal frame body and rail body,
It is sometimes seen that the horizontal frame is assembled from three parts, including the rail body and the rail part, but while it is possible to assemble it firmly, it takes time to join the rail body and the rail part, and the position of the joint may shift, resulting in unnecessary gaps. This has caused problems such as causing bumps and hindering the smooth sliding of sliding doors, etc.

This design has sufficient strength to prevent deformation due to external forces, allows sliding doors to slide smoothly, is easy to manufacture and assemble, and is inexpensive overall. The purpose is to provide

Hereinafter, preferred specific examples of the horizontal frame used in the fittings frame according to this invention will be described with reference to the drawings.

Figures 1 to 4 show school partitions 70,
In particular, both sliding doors 78, 79 and transom sliding door 8
In the partition frame 71 for 0.81, specific examples 10 and 40 of horizontal frames used in the fitting frame according to this invention are shown, which are embodied as upper frames and blanks.

The upper frame 10 is composed of an upper frame body 11 as a horizontal frame body made of a strip-shaped steel plate, and an upper frame rail body 12 assembled to the upper frame body 11 as a rail body made of an aluminum alloy profile. ,
The blind 40 is composed of a blank body 41 as a horizontal frame body made of a strip-shaped steel plate, and a blank rail body 42 assembled to the blank body 41 as a rail body made of an aluminum alloy profile.

The upper frame 10 and the blank 40 are a pair of vertical frames 7
The partition frame 71 is framed in a partition frame 71 together with a threshold 73 between the two spaces, and the partition frame 71 framed in this way is
Double sliding doors 78, 79 between Mume 40 and threshold 73
In addition, transom sliding doors 80 and 81 are arranged between the upper frame 10 and the blind 40.

More specifically, the upper frame 10 consists of an upper frame main body 11 and an upper frame rail main body 12 having a cross-sectional shape as understood from FIGS. 2 and 3,
The upper frame body 11 is formed by bending a long steel plate, such as a zinc-coated galvanized steel plate or an inexpensive stainless steel plate, using a press machine, folding machine, roll forming machine, etc. A pair of side walls 14 and 15 formed by bending both sides of the strip substrate 13 in a substantially vertical direction;
Folded portions 16 and 17 are formed by folding back the tips of the side walls 14 and 15 so as to form bag grooves 18 and 19 together with 5, and inner base portions of the folded portions 16 and 17 are bent inward to protrude. The strip substrate 13 has a pair of inward flanges 20, 21 and an opening formed in the longitudinal direction between the pair of flanges 20, 21. The projecting walls 22 and 23 are formed on both sides.

The upper frame rail main body 12 is made by cutting an aluminum alloy profile into a predetermined length.
A strip-shaped rail board 25 that is provided with approximately the same width as the opening formed between the pair of inward flanges 20 and 21 and closes this opening, and the strip-shaped rail board 2
Fitting grooves 30, 31 are provided on both sides of the upper frame body 11, and are provided on both sides of the upper frame body 11 so as to extend upright on one surface and cooperate with the band-shaped rail board 25 to fit the inward flanges 20, 21 of the upper frame main body 11. A pair of hook-shaped edges 26,2 having
7, and an inward flange 2 that fits into the fitting grooves 30 and 31 formed on the hook-shaped protruding edges 26 and 27 thereof.
0 and 21 are protruded in parallel to the other surface of the strip-shaped rail board 25 so that the distal ends of the fitting grooves 30 and 21 cooperate with and lock with the protrusions 32 and 33 protruded from the bottoms of the fitting grooves 30 and 31. A pair of rail portions 28 and 29 are provided.

Similar to the upper frame 10, as shown in FIG. 2 and FIG. Fold back to bag groove 48,
49, and a pair of inward flanges 5 protruding by bending the inner root portions of the folding parts 46, 47 inward.
An open body 41 made of a zinc steel plate or the like has an opening extending in the longitudinal direction between 0 and 51, and a strip rail board 57 that closes the opening of this open body 41. A pair of hook-shaped projecting edges 58 and 59 are formed and have fitting grooves 62 and 63 in which the inward flanges 50 and 51 are fitted in cooperation with the band-shaped rail substrate 57. The protrusions 6 project from the bottoms of the fitting grooves 62, 63 at the tips of the inward flanges 50, 51 that are fitted in the fitting grooves 62, 63 formed in the fitting grooves 58, 59.
A pair of rail parts 60 and 6 are provided on the other surface of the band-shaped rail board 57 so as to cooperate with and lock with the rail parts 4 and 65.
A pair of flanges 50, 51 of the rail body 41 are connected to the rail portions 60, 61 of the rail body 42 and hook-shaped protrusions 58, 59. It fits into fitting grooves 62, 63 formed between the fitting grooves 62, 63, and is firmly locked by protrusions 64, 65 provided at the bottoms of the fitting grooves 62, 63.

Note that the strip-shaped substrate 43 of the main body 41 has vertical walls 52, 53, 5 on the opposite side from the rail parts 60, 61.
4 and grooves 55 and 5 of both sliding doors 78 and 79.
6 is formed, and both sliding doors 78, 79 slide with grooves 76, 77 of the threshold 73.

The upper frame 10 and the blind eye 4 configured as described above
0 is framed by the partition frame 71 with both ends abutting against the sill 73 and between the pair of vertical frames 72, and tightened with a connecting rod 74 and a nut (not shown). That is, since the vertical frame 72 is provided with a groove 75 extending in the length direction on surfaces facing each other, both ends of the upper frame, blinds, and sills 10, 40, and 73 are fitted into the groove 75, and both ends are They are tightened by a connecting rod 74 that butts against the bottom surface of the groove 75 and passes through the inside thereof, and a nut that is screwed into the threaded portions at both ends of the connecting rod 74, and they are firmly assembled between the pair of vertical frames 72. The vertical frame 72 and the partition frame 71 are assembled together.

As mentioned above, in this invention, the rail body on which the sliding door etc. slides has a band-shaped rail board that closes the opening formed between a pair of inward flanges of the horizontal frame main body, and a band-shaped rail board that extends on both sides of the band-shaped rail board. , a hook-shaped protrusion having a fitting groove that cooperates with the band-shaped rail board to fit the inward flange of the horizontal frame body; It is composed of a rail part that protrudes parallel to the band-shaped rail board so as to lock the tip end side of the flange,
By strongly connecting the horizontal frame body and keeping the distance between the hook-shaped protruding edge of the rail body and the rail part constant, the sliding door can slide smoothly without rubbing against the horizontal frame body, and
Since there is no unnecessary gap, the sliding door can be prevented from swinging sideways and can be opened and closed quietly.

In addition, it is possible to obtain a horizontal frame that requires less assembly effort and is inexpensive as a whole, and since no loosening occurs, the horizontal frame main body and the rail main body can be firmly latched over a long period of time.
