Description

[Detailed Description of the Invention] The present invention relates to a metal stile door that prevents fingertips from being injured when opening and closing the door.

A metal stile door is, for example, as shown in FIG. Bottom 2. Assemble the 3rd left stile and the 4th right stile into a square,
A panel P like a glass plate is fitted inside the panel P, but the four corners that are formed there are usually cut at right angles and the root ends are exposed, so it is difficult to clean and clean the ground. When the lock is closed, the tips of the fingers and toes are easily damaged, especially at the lower corner of the lock-side vertical stile 3, which is indicated by a right circle.

For this reason, Japanese Utility Model Application Publication No. 53-34843 proposes installing an L-shaped corner piece made of synthetic resin.

However, in this case, in order to attach the piece so that it does not protrude, the longitudinal end of the lower stile is cut off by the thickness of the horizontal plate.

Furthermore, in the stile assembly of this invention, a step is created between the vertical stile and the lower stile by the thickness of the vertical stile, so there is a problem that the tightness between the door frame and the door stile is incomplete.

The present invention was developed to solve the problems of the conventional products as described above, and uses vertical and horizontal frame members and corner blocks of specific shapes.

One embodiment will now be described with reference to the accompanying drawings.

As shown in FIG. 2, the short root 3 has an indoor wall, abbreviated as an inner wall 3a, and an outdoor wall, abbreviated as an outer wall 3b, forming a rectangular hollow 3e in the center of the ocean with a panel side wall 3C and a skirt wall 3d. The panel grooves 3f are formed on the side walls 3c of the panel, and the hem grooves 3g are formed on the hem walls 3d. They are bent to form holding pieces 3h and 3i.

In addition, the panel side wall 3C has mounting screw holes 6a at positions corresponding to the tapping holes 4j and 4k of the lower stile, which will be described later.
, 6b are provided, and operation holes 8a, 8b are similarly provided at corresponding positions on the skirt wall 3d.

The lower end of the hollow 3e is a portion through which a horizontal arm of a corner block 5, which will be described later, is inserted, and the presence of the hem groove 3g serves to protect the hem wall 3d from damage.

The lower stile 4 basically has the same structure as described for the short root 3, so it can be read by replacing the symbol 3 in the short root with 4.

However, tapping holes 4j and 4k are provided on the hollow 4e side of the panel side wall 4C and the hem side wall 4d, respectively, and the horizontal arm of the corner block is not inserted through the hollow 4e, but is attached by being inserted into the hem groove 4g. .

Further, the side walls 4 a', 4 b' forming the hem groove 4g are not extensions that are flush with the inner and outer walls 4a, 4b (7).

That is, the distance between both groove walls 4a'-4b' of the hem groove 4g is as follows:
The distance between the inner and outer walls 3a-3b of the short root is the same as the outer distance between the inner and outer walls 3a-3b, but the outer distance between the inner and outer walls 4a-4b is the same as the inner-outer wall 3a of the short root.
, 3b on both sides, that is, equal to the inner spacing of the inner and outer walls 3a-3b of the short root.

Therefore, 4a and 4a' and 4b and 4b' are connected by expanding so as to form shoulders s and s' with the thickness of walls 3a and 3b being steps.

Note that the term "shoulder" here refers to a step that is perpendicular and not curved.

Therefore, when assembling the stile, first hold the clamping pieces 3h and 3i at the lower end of the short root 3 at the height h of the inner and outer walls 4a and 4b of the lower stile.
If you make a notch and then insert the left end of the lower stile into this notch, the outer spacing of the inner and outer walls of the lower stile is exactly equal to the inner spacing of the inner and outer walls of the short root, as described above, so the lower stile will be a short root. It is inserted glitteringly between the inner and outer walls of the panel, and stops when it comes into contact with the panel side wall 3C of the short root.

If the short root is then pushed down, the lower ends of its inner and outer walls abut against the shoulders s and s' and are assembled in the state shown in FIG. 3.

Moreover, as described above, since the outer distance between the inner and outer hem walls 4a' and 4b' of the lower stile is equal to the outer distance between the inner and outer hem walls 3a and 3b of the short root, the inner wall 3a and the hem wall 4a' , and outer wall 3
b and the skirt wall 4b' are joined so that their outer surfaces are flush with each other.

Then, at the combined lower corner, the height of the lower stile hem wall is defined as height H, the distance between the hem walls is defined as depth, and the distance from the abutting surface to the outer end of the short root is defined as width M. A rectangular space is left.

In the present invention, a corner block 5 shown in FIG. 4 is used to fill this space and firmly connect the vertical and horizontal frames, as well as to protect toes from injury.

Although the corner block is a connecting member, the corner block has vertical arms 5b and horizontal arms 5C from its main body 5a as shown in the figure.
It has an L-shaped body with a protruding part, and since it is a protective member for toes and the like, its material is appropriately made of ordinary synthetic resins such as polyolefin and polyvinyl chloride.

Since the main body part 5a is sized to fill the above-mentioned space, it is a rectangular body with a height of H1, a depth of L, and a width of M; This provides a rounded corner of the door to which the block is attached.

The vertical arm 5b is bent as 5b-5b'-5b'' to have a U-shaped cross section so that it is exactly inserted into the hollow 3e of the short root, and is attached to the back side of the panel side wall 3C. A mounting screw hole 6C is provided in the abuttable wall 5b' at a position corresponding to the tapping hole 4k of the lower stile.

The horizontal arm 5C may have any size or shape as long as it can be inserted into the hem groove 4g at the end of the lower stile without wobbling.

As is already clear, in order to install this corner block, insert the vertical arm of the corner block 5 into the hollow 3e of the short root of a part of the corner assembled in the state shown in Fig. 3.
5b' wall is brought into contact with the back side of the panel side wall 3C, and as shown in FIG. They are passed through a certain screw hole 6b and fixed together into a tapping hole 4k provided in the lower frame.

That alone is not enough to connect both the vertical and lower stile, so insert the assembly screw 7 in the same way through the screwdriver operation hole 8a provided in the short root, pass through the assembly screw hole 6a provided in the panel side wall, and connect the lower stile. It may be screwed into the tapping hole 4j.

When this screwing is completed, the horizontal arm 5C of the block is, of course, firmly inserted into the hem groove 4g of the lower stile.

Above is an example of the lower corner of the door where the short root on the lock side is joined to the lower stile, but if necessary, two or more corners can be joined simply and precisely in the same way, and the roundness of the corner block can prevent unforeseen problems. It is self-evident that injuries to people are prevented.

As mentioned above, the present invention consists of only vertical and horizontal stiles and corner blocks of specific shapes, and the main cutting of the stile material when assembling the stile is a right angle cut.

Furthermore, since the notch of the clamping piece at the lower end of the short root can be easily made on site together with the main cutting, the number of man-hours can be significantly reduced.

Furthermore, when the top, bottom, left, and right sides of the stile are assembled, the outer surface of the hem wall and the outer surface of the short root are flush with each other, with no difference in level, due to the presence of the shoulders provided on the side stile.

Therefore, when the door of the present invention is attached to the framework of a door from Tokyo, the four peripheries of the door can be brought into contact with the door frame flush with no difference in level, resulting in the advantage of excellent sealing performance.
