Description

The present invention relates to a frame material for a frame door that does not cause rattling of the end plate and does not cause an appearance defect due to wraparound of an adhesive, and a frame door using the same.

A stile door is known as a fitting that can be attached to an opening of a building. The basic structure of the stile door is that the stile member and the end plate are sandwiched and fixed by a pair of opposite frame members (see Patent Document 1).

A stile member mounting step is formed on the holding surface of each frame member by digging one end in the width direction (the side on which the stile member is attached) in a stepped manner, and the stile is formed on the stile member mounting step. Members are placed. Further, on the sandwiching surface of each frame member, a end plate mounting step portion is formed by digging the other end portion (the side to which the end plate is attached) in the width direction in a stepped manner, and the end plate is formed on this end plate mounting step portion. Be placed.

An adhesive is applied to the sandwiching surface of each frame material, and a frame door is formed by solidifying the adhesive while the frame members are pressed from both the front and back sides, and a plurality of types of frame members and end plates having different thicknesses are formed. Can be uniformly sandwiched and fixed with one type of frame material.

JP-A-2007-211443 (Fig. 1)

In the conventional frame door, as described above, a plurality of types of frame members and end plates having different thicknesses can be uniformly sandwiched and fixed by one type of frame member, but when the end plate is thin, the end plate and the end plate mounting step portion can be used. There is a risk that a gap will be created between the two and cause rattling. In such a case, an adhesive is separately applied between the end plate and the end plate mounting step portion to prevent rattling.

However, since the adhesive is applied manually by the field workers in the factory, the amount of the adhesive applied may be excessive if the field workers who are inexperienced perform the work. In this case, when the adhesive is solidified by pressing from both the front and back sides of the frame member, the adhesive applied to the end plate mounting step portion crosses the boundary portion between the frame material and the end plate and squeezes out to the outside, resulting in an appearance. There was a problem of producing defective products due to defects.

The present invention has been made in view of the above-mentioned conventional problems, and the end plate can be attached without rattling, and the adhesive does not squeeze out at the boundary portion between the end plate and the frame material, and the appearance is not deteriorated. It is an object of the present invention to provide a frame material and a frame door using the frame material.

The invention according to claim 1 states that "the end plate 300 is arranged at a boundary portion between the end plate 300 and the stile members 200 arranged on the four circumferences of the end plate 300, and the end plate 300 and the stile member 200 are sandwiched and fixed from both front and back sides. It is a frame material 10 for a frame door,
A end plate mounting step 16 on which the end plate 300 is arranged is formed at an end portion of the holding surface 14 of the frame material 10 on the side where the end plate 300 is attached.
The digging depth D of the end plate mounting step 16 dug into the holding surface 14 gradually increases from the tip end side of the end plate 300 side toward the stile member 200 side, and the bottom surface 16a of the end plate mounting step 16 It is formed as an inclined surface to which the adhesive S2 for adhering the end plate 300 is applied . "

The invention according to claim 2 states that "the end plate 300, the frame members 200 arranged on the four circumferences of the end plate 300, and the end plate 300 are arranged on both the front and back sides at the boundary between the end plate 300 and the frame member 200. It is a frame door made of a frame material for sandwiching and fixing the frame member 200 from both the front and back sides, and the frame material is the frame material 10 according to claim 1. "

According to these inventions, the digging depth D of the end plate mounting step 16 dug into the holding surface 14 is formed so as to gradually increase from the end plate 300 side toward the stile member 200 side. Then, since the bottom surface of the end plate mounting step portion is an inclined surface that inclines downward from the end plate side toward the stile member side, the adhesive applied to the bottom surface of the end plate mounting step portion is a pair of front and back frame materials. When the end plate is sandwiched between the heads, the flow flows from the end plate side to the stile member side, and the adhesive does not wrap around the boundary between the end plate and the frame material and is not exposed to the outside, resulting in poor appearance. It can be prevented from causing.

It is a perspective view which shows the frame material which concerns on this invention. It is an enlarged end view of the frame material of FIG. It is a figure which shows the frame door which incorporated the frame material which concerns on this invention. FIG. 1 is a cross-sectional view taken along the line AA'in FIG. It is a figure which shows the manufacturing method of a stile door. It is another figure which shows the manufacturing method of a stile door.

Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a frame material 10 according to the present invention, and FIG. 2 is an enlarged end view thereof.

As shown in these figures, the frame material 10 is a long member obtained by molding a metal material such as a wood material or an aluminum alloy or a resin material by a known method such as extrusion molding, and is a decorative surface 12 on the surface side. (The lower surface in FIG. 2) is decorated with an uneven curved surface, and on the opposite back surface side, a flat holding surface 14, a end plate mounting step 16 and a stile member mounting step 18 are arranged. It is formed.

One end in the width direction of the frame member 10 (the end on the side to which the end plate 300 described later is attached; the left end in FIG. 2) is dug shallowly in a stepped manner with reference to the holding surface 14. The recessed portion is the end plate mounting step portion 16. And let D be the digging depth of this part.

The bottom surface 16a of the end plate mounting step 16 formed by digging shallowly in steps with respect to the holding surface 14 has a shallow tip side (left side in FIG. 2) on the end plate 300 side and a back side on the stile member 200 side. It is an inclined surface (in other words, an inclined surface that inclines downward from the tip side toward the back side) so that the side (right side in FIG. 2) becomes deeper.

Assuming that the digging depth on the tip side, which is the shallowest portion, is d1 and the digging depth on the back side is d2, the bottom surface 16a of the end plate mounting step 16 gradually increases from d1 to d2. The digging depth d1 on the tip side is set to be slightly smaller than the length of about half the thickness of the end plate 300, which will be described later, and the digging depth d2 on the back side is set to be slightly larger.

The other end in the width direction of the frame member 10 (the end on the side where the frame member 200 to be described later is attached; the right end in FIG. 2) is dug in a step shape larger than the end plate mounting step 16. The deeply dug recessed portion is the stile member mounting step portion 18.

The digging depth d3 (the length from the holding surface 14 to the bottom surface 18a of the stile member mounting step 18) of the stile member mounting step 18 is set to be slightly smaller than about half the thickness of the stile member 200 described later. Has been done.

The boundary portion at the corner between the holding surface 14 and the stile member mounting step portion 18 (the position of this boundary portion roughly coincides with the portion having the largest thickness of the frame member 10) is cut out in a tapered shape. The notched tapered surface is the adhesive-coated surface 20.

A concave groove 22 is formed on the holding surface 14 over the entire length in the longitudinal direction. In the concave groove 22, when the frame member 200 and the end plate 300 are sandwiched and fixed by a pair of front and back frame members 10 described later, the excess amount of the adhesive S1 applied to the adhesive application surface 20 turns to the end plate mounting step portion 16 side. It is for preventing squeezing, and its size is not particularly limited, but in this embodiment, it is formed as having a width of 3 mm and a depth of about 5 mm.

In this embodiment, the concave groove 22 is formed at a position biased toward the stile member mounting step 18 so that the surplus of the adhesive S1 applied to the adhesive application surface 20 can flow into the concave groove 22 more quickly. However, it may be formed at a position biased toward the end plate mounting step 16 side, or may be formed at a position exactly in the middle between the frame member mounting step 18 and the end plate mounting step 16. ..

Next, the frame door 100 using the above-mentioned frame material 10 and an assembling method thereof will be described. The stile door 100 is roughly composed of a stile member 200, a mirror plate 300, and a frame material 10 (see FIGS. 3 to 4).

The stile member 200 is a combination of a pair of left and right vertical stile members 200a and 200b and a pair of upper and lower horizontal stile members 200c and 200d in a rectangular frame shape, and decorative plates 202 are attached to both the front and back surfaces thereof. ..

The end plate 300 is a face material that covers the opening inside the frame of the frame member 200, and is a thin plate-like member such as a glass plate, an acrylic plate, or a solid plate, or a louver (a plurality of elongated blade plates, parallel to each other at predetermined intervals). (Arranged in) etc. are used as appropriate. In this embodiment, a glass plate is used as the end plate 300.

Next, a method of assembling the frame door 100 will be described with reference to FIGS. 5 to 6. First, four long and short frames and two sets of frame members 10 are cut, and one set (four) of them is combined in a rectangular frame shape and placed on the installation surface G. Each frame member 10 is formed in a rectangular frame shape by diagonally cutting off both end portions in the longitudinal direction (FIG. 3) and adhering and fixing the cut end faces to each other with an adhesive.

Next, as shown in FIGS. 5 and 6 (A), the adhesive S1 is linearly applied to the adhesive-coated surface 20 of the frame material 10, and the adhesive S2 is applied to the bottom surface 16a of the end plate mounting step 16. Apply in scattered dots. The adhesive S1 is applied linearly because a sufficient amount of the adhesive S1 is required to firmly bond and fix the frame member 10 and the stile member 200. On the other hand, the adhesive S2 is applied in a scattered manner because it is sufficient if the rattling between the frame material 10 and the end plate 300 can be suppressed, and mechanical strength is not required so much. The types of the adhesive S1 and the adhesive S2 may be appropriately selected according to the material of the member to be bonded (specifically, the frame material 10 or the end plate 300), and even if they are the same type, they are different. It may be.

When the application of the adhesives S1 and S2 to each frame material 10 is completed, the end plate 200 is arranged on the end plate mounting step 16 of the frame material 10 assembled in a rectangular frame shape as shown in FIG. 6 (B). The frame member 300 is arranged on the frame member mounting step portion 18.

At this time, the adhesive S1 linearly applied to the adhesive application surface 20 accumulates in the space X formed between the adhesive application surface 20 and the end surface of the stile member 200, and the surface thereof is the adhesive. It is more raised than the coated surface 20.

On the other hand, the adhesive S2 applied in a scattered manner to the end plate mounting step 16 is gradually spread between the end plate 300 and the bottom surface 16a of the end plate mounting step 16 by the weight of the end plate 300.

When the arrangement of the stile member 200 and the end plate 300 is completed, another set of frame members 10 remaining as shown in FIG. 6C is arranged so that the holding surfaces 14 face each other, and the load is applied by the press machine P. And press.

At this time, most of the adhesive S1 accumulated in the space X surrounded by the upper and lower adhesive application surfaces 20 and the end surface of the stile member 200 is the holding surface 14 of the lower frame material 10 and the upper side. It moves to the end plate 300 side through the gap between the frame material 10 and the holding surface 14, and flows into the concave groove 22. A part of the adhesive S1 is spread along the gap between the frame member 10 and the stile member 200.

On the other hand, the adhesive S2 between the end plate 300 and the end plate mounting step 16 is further expanded by the load of the press machine P, but as described above, the bottom surface 16a of the end plate mounting step 16 is from the end plate 300 side. Since it is configured as an inclined surface that inclines downward toward the stile member 200 side, the adhesive S2 flows toward the stile member 200 side having a wider space as shown by the arrow in FIG. 6 (B). As a result, the adhesive S2 is not spread toward the end plate 300 side.

Then, pressing is performed for a predetermined time, and when the adhesives S1 and S2 are cured, the press machine P is unloaded and the stile door 100 is completed.

According to the frame material 10 of the present embodiment, the bottom surface 16a of the end plate mounting step portion 16 is configured as an inclined surface that inclines downward from the end plate 300 side toward the stile member 200 side. As shown by the arrow in FIG. 6B, the adhesive S2 applied to the bottom surface 16a flows toward the frame member 200 side having a wider space, and may be spread toward the end plate 300 side. Absent. Therefore, it has become possible to prevent the occurrence of defective products such as the adhesive S2 being exposed at the boundary between the frame material 10 and the end plate 300 during the manufacture of the frame door 100.
