Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner cap attached to a corner of a glass in a sash in which glass is mounted on a sash frame via a gasket. 2. Description of the Related Art A sash conventionally used is provided with a vertical and horizontal sash frame material, a glass and a gasket, a gasket is attached to the periphery of the glass, and the glass is recessed in the sash frame material via the gasket. Some are known to fit in. [0003] Assembling of this sash is generally performed as follows. First, a long gasket wound and held on a bobbin is cut into a length equal to the peripheral length of the sash frame. This gasket has a concave shape in cross section having a bottom surface and a pair of side surfaces rising in one direction from the bottom surface, and can store the thickness of glass. The cut gasket is gradually fitted along the glass rim and attached to the glass rim. [0004] The gasket is cut into a predetermined position before being fitted into the glass. The notch is provided at a position corresponding to a corner of the glass when the gasket is attached to the glass, and the gasket is bent at this position and attached along the periphery of the glass. At this time, the corner of the glass is exposed from the gasket. The reason why the gasket is provided with a cut is that when the gasket is bent at the corner of the glass,
The gasket is distorted at the bent part, the shape of the gasket expands outward, and a gap is created between the gasket and the gasket.When the glass is inserted into the concave groove of the sash frame material in the later process, the gasket This is because the thickness of the gasket interferes with the fitting, the adhesion between the glass and the gasket is lost, and the watertightness cannot be maintained. After the gasket is fitted on the periphery of the glass, the cut ends of the gaskets facing each other are bonded or welded together to combine the glass and the gasket integrally. Thereafter, the peripheral edge of the glass having the gasket is sequentially fitted into the concave grooves of the vertical and horizontal sash frame materials, and finally, the corners of the sash frame material are screwed to fix the sash frame, and integrated with the glass. Is to be combined. Conventionally, such an assembling operation has been performed manually, and is an operation of handling glass. Therefore, there has been a problem that an operator may be injured when a human body comes into contact with a corner of the glass. [0008] Such assembling work is generally performed by a processing agency, which prepares a long gasket in advance and combines it with the glass and sash frame material carried in. Was. In recent years, for the purpose of improving customer satisfaction, shortening of product delivery time has been demanded. As a result, the sash assembly work at the processing agency is simplified and the working time is shortened. As one of them, a gasket is attached to the glass in advance at a factory or the like, and the glass is transported to the processing agency. It is strongly desired. Conventionally, glass is carried into a processing agency with the glass fitted in a wooden frame, and since the glass periphery is protected by the wooden frame, the glass is not damaged. However, when carrying in a state in which the gasket is attached to the periphery of the glass, the glass is exposed from the cut of the gasket at the corner of the glass and is not protected. There was a risk of collision and damage. In addition, the gasket was crushed and deformed by the weight of the glass, which affected the fitting of the sash frame material into the concave groove. On the other hand, as a corner cap for covering a corner of glass, for example, a first corner cap disclosed in Japanese Utility Model Publication No. 54-5569 is known. This first corner cap is formed by bending a channel-shaped member having a U-shaped cross section with one opening and bending it at a right angle. The first corner cap covers and covers the corner of the glass and is fitted inside a gasket having a concave cross section. A protruding piece that stands upright at right angles to the side face is formed at the side opening edge of the corner member, and the gasket is pressed and held between the protruding piece and the sash frame. A second corner cap disclosed in Japanese Utility Model Laid-Open No. Sho 54-116942 is also known. The second corner cap is formed by bending a member having a U-shaped cross section with one opening at a right angle, and integrally forming right-angle protruding edges at both ends on the bottom rear surface, and attached to a glass corner, The gasket is sandwiched and fixed between the right-angled protruding edge and the bottom rear surface by bending the right-angled protruding edge through the gasket. [0014] A third corner cap disclosed in Japanese Utility Model Publication No. 57-55914 is also known. The third corner cap has a concave groove for swallowing the corner of the glass, and is mounted on a glass corner where the glass is exposed after the gasket is mounted on the glass, with the watertight agent being filled in the concave groove. [0015] The first corner cap and the second corner cap described above are fitted and attached to the corners of the glass, and the first and second corner caps are recessed in the gasket. Since the gasket is mounted by fitting, the portion of the gasket fitted into the corner cap is expanded to increase the thickness of the gasket, and the height of the portion engaging with the concave groove of the sash frame material provided on the side of the gasket. Therefore, it is difficult to mount the sash frame material in the groove. Further, since the gasket is grounded when the glass is leaned, the gasket cannot be prevented from being crushed. Since the third corner cap described above is mounted by fitting the gasket to the glass after the gasket has been mounted on the glass, it is possible for the worker to be injured by the contact between the human body and the glass corner during the operation. It cannot be lost. Further, depending on the degree of filling of the watertight agent, there is a possibility that the corner member may be removed from the glass corner by an impact due to vibration during transportation. Accordingly, an object of the present invention is to provide a glass corner cap capable of solving the above-mentioned problems. According to the present invention, a pair of side plates 20 facing each other and a substantially hook-shaped back plate 21 integrally provided between two adjacent sides of the pair of side plates 20 are provided. The storage space 23 has a pair of fitting surfaces 26 facing each other at a distance substantially the same as the thickness of the glass 1 and a substantially same angle as the corner 1 a of the glass 1. A main body 22 having a first bottom surface 24 and a second bottom surface 25, and a first bottom surface 24 at one opening edge side of the back plate 21.
A first locking piece 30 thinner than the back plate 21 provided continuously and integrally with the second bottom surface 2 on the other opening edge side of the back plate 21;
5 is provided with a second locking piece 31 which is thinner than the back plate 21 provided integrally and continuously, and a pair of fitting surfaces 26 in a state where the storage space 23 of the main body 22 is fitted into the corner 1 a of the glass 1.
Are in contact with both sides of the glass 1, the first bottom surface 24 and the first locking piece 30 are in contact with one end face of the corner 1 a of the glass 1, and the second bottom face 25 and the second locking piece 31 are Contact the other end face at the corner 1a of the
The body 22 fits into the notch 3 of the gasket 2 attached to the glass 1, the bottom of the concave groove 14 of the gasket 2 contacts the first locking piece 30 and the second locking piece 31, and This is a glass corner cap in which the outer surface of the back plate 21 projects beyond the outer surface of the gasket 2. [Operation] When the gasket 2 is attached with the corner cap 4 attached, the concave groove 14 of the gasket 2 does not fit into the main body 22, and the gasket 2 is pushed and expanded to increase the width. There is no. Thereby, the glass 1 on which the corner cap 4 and the gasket 2 are attached can be easily mounted in the concave groove of the sash frame member. The first locking piece 3 of the corner cap 4
Since the second locking piece 31 is pressed against the end surface of the glass 1 at the bottom of the concave groove 14 of the gasket 2, the corner cap 4 can be supported by the gasket 2 so as not to come off.
Thereby, the corner cap 4 does not come off when carrying the glass on which the gasket 2 and the corner cap 4 are attached. Further, since the outer surface of the back plate 21 of the main body 22 projects beyond the outer surface of the gasket 2, the outer surface of the back plate 21 of the main body 22 is grounded when the glass 1 on which the gasket 2 and the corner cap 4 are mounted is leaned. Gasket 2 is not grounded. This prevents the gasket 2 from being broken when the glass 1 is transported and stored with the glass 1 upright. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an overall schematic front view before attaching a sash framework. A gasket 2 is attached to the periphery of the glass 1, and the corner of the gasket 2 is notched. Corner caps 4 are respectively attached to the notches 3 of the gasket 2 to cover corners of the glass 1 exposed from the notches 3 of the gasket 2. Thus, the glass 1 is not damaged when the glass 1 is transported, and the human body is not damaged during the operation. The upper and lower horizontal sash frame members 5 and the left and right vertical sash frame members 6 are cut at both ends in the longitudinal direction at 45 degrees, and the concave grooves 7 are fitted to the respective gaskets 2 and mounted. The sash frames are joined and joined to form a sash. As shown in FIG. 2, the glass 1 is a double-layer glass in which a pair of glass plates 10 are joined via a sealer 11. The gasket 2 has a bottom plate 12 as shown in FIG.
And a pair of side plates 13, a main body 15 having a concave groove 14 in a U-shaped cross section, and a pair of plates 16 provided integrally along the opening edges of the pair of side plates 13. A portion of the main body 15 of the gasket 2 facing the corner of the glass 1 is
And the remaining pair of plates 16
The portions are bent so that the adjacent main body portions 15 are at 90 degrees, and the cutout end faces 17 are at 90 degrees to each other. As described above, when the gasket 2 is attached to the periphery of the glass 1, the corner of the glass 1 is exposed from the cutout 3 of the corner of the gasket 2, and the corner cap 4 is attached to the exposed portion. is there. As shown in FIG. 3, the corner cap 4 is substantially provided integrally with a pair of rectangular flat plate-shaped side plates 20 opposed to each other and between one adjacent two sides of the pair of side plates 20. A back plate 21 bent at 90 degrees forms a main body 22. The main body 22 is formed as a box having a U-shaped cross-section having a storage space 23 inside with two adjacent sides of the pair of side plates 20 serving as opening edges. The bottom surface of the storage space 23 of the main body 22 (the inner surface of the back plate 21) is 90 degrees between the first bottom surface 24 and the second bottom plate 25. Are substantially parallel to each other, form a fitting surface 26, are integrally provided with a projection 27, and a portion near the opening edge is formed as a guide surface 28 which is sequentially inclined toward the opening edge. The protrusion 27 is a straight line extending from the bottom of the storage space 23 to the boundary between the fitting surface 26 and the guide surface 28. However, the present invention is not limited to this, and may be a cone, a disk, or a letter. It may be a linear projection that bends in a curved manner. The corner 21a of the back plate 21 is approximately 9
Two ridges a and one valley b with concave shape
In a valley b of the corner 21a, a through hole 29 from which the corner 1a of the glass 1 projects is formed as shown in FIG. As shown in FIG. 4, the amount of protrusion of the glass 1 is within a range not exceeding the line 1 connecting the vertices of the two peaks a, and the corner 1a of the glass 1 comes into contact with another article. It will not harm or be damaged. The reason why the through-holes 29 are provided is that the sealer 11 is interposed between the two glass plates 10 in the double glazing, and the sealer 11 forms an accurate angle (right angle) at the corner 1 a of the glass 1. Because it is difficult to manufacture and may swell, it is provided as the reverse. Further, the through hole 29 can also serve as a drainer from the gasket 2. A first locking piece 30 and a second locking piece 31 are integrally provided near the bottom of the opening edge of the main body 22 (both end faces of the back plate 21). This first locking piece 3
0 is continuous with the first bottom surface 24 of the storage space 23 and is thinner than the thickness of the back plate 21, and a stepped portion is formed between the outer surface of the back plate 21 and the outer surface of the first locking piece 30. 32 are formed. The inner surface of the second locking piece 31 is provided in the storage space 23.
Of the rear surface 21 and the outer surface of the second locking piece 31 are formed so as to be flush with the second bottom surface 25 and thinner than the thickness of the back plate 21. First locking piece 3
The 0 and the second locking pieces 31 are open by 90 degrees. The first locking piece 30 and the second locking piece 31 have the same width as the thickness of the glass 1 and come into contact with the two end faces of the glass 1 at the corner 1a as shown in FIG. The width of the first and second locking pieces 30 and 31 may be any width that does not exceed the thickness of the glass 1 and may be smaller than the thickness of the glass 1. Next, an example of an operation for attaching the corner cap 4 and the gasket 2 to the glass 1 will be described. As shown in FIG. 2, the corner caps 4 are fitted into the corners 1a of the glass 1 and attached. Thereby, the corner 1a of the glass 1 is stored in the storage space 23 of the main body 22 of the corner cap 4, the corner 1a slightly protrudes from the through hole 29, and the first bottom 24 and the second bottom 24 as shown in FIG. 25 and the first and second locking pieces 30 and 31 abut on two end faces of the glass 1 bordering the corner 1a. The pair of fitting surfaces 26 (the inner surfaces of the pair of side plates 20) of the body 22 of the corner cap 4 are shown in FIG.
As shown in FIG.
Abuts against both side surfaces of the glass 1 to slightly expand and deform the pair of side plates 20. When the corner cap 4 is fitted into the corner 1a of the glass 1, it can be smoothly fitted by the guide surface 28 formed on the inner surface of the storage space 23 of the main body 22. The gasket 2 is attached to the periphery of the glass 1 and the notch 3 is fitted into the main body 22 of the corner cap 4 so that the main body 22 can be removed from the notch 3 of the gasket 2 as shown in FIGS. Exposed. Thus, the first of the corner caps 4
The locking piece 30 and the second locking piece 31 are formed in the groove 14 of the gasket 2.
The first and second locking pieces 30 and 31 are housed in the bottom plate 12.
Is pressed against the end face of the glass 1 to support the corner cap 4 so as not to come off. As shown in FIG. 4, the bottom plate 12 of the gasket 2
Of the body 22 abuts against the step 32 of the main body 22, and the outer surface of the back plate 21 of the main body 22 protrudes outward from the bottom plate of the gasket 2 by a dimension c more than the outer surface. That is, the dimension of the step portion 32 of the corner cap 2 is larger than the thickness of the bottom plate 12 of the gasket 2. As described above, even when the glass 1 with the gasket 2 mounted thereon is transported, even if the glass 1 is set up, the grounded portion is the back surface of the corner cap 4 and the gasket 2 is grounded. It can be prevented from being caught between the glass 1 and being deformed. Further, the notched end face 17 of the gasket 2 corresponds to the opening edge of the main body 22 of the corner cap 4 (a pair of side plates 2).
0, and the opening edges of the pair of side plates 20 are close to the side plates 13 of the gasket 2 as shown in FIG.
Project slightly outward by a dimension d. As described above, when the glass 1 on which the gasket 2 is attached is overlapped, the side surfaces of the corner cap 4 come into contact with each other and the gaskets 2 do not come into contact with each other, so that the gasket 2 is not deformed. The dimension between the facing fitting surfaces 26 of the corner caps 4 may be the same as the thickness of the glass 1. However, the thickness of the glass 1 is not always constant, and there are some tolerances. The projection 27 abuts on the glass surface to elastically deform the side plate 20 so that the corner cap 4 cannot be removed from the corner 1b of the glass 1, and the side plate 20 elastically urges the glass surface. Thereby, it is possible to prevent the corner cap 4 from being pulled out of the glass 1 before the gasket is attached. FIG. 6 shows a second embodiment of the corner cap, in which the corners 21a of the back plate 21 are substantially arc-shaped and the through holes 29 are not formed. There is no protrusion 27 on the fitting surface 26,
The width of the first and second locking pieces 30, 31 is reduced. FIG. 7 shows a third embodiment of the corner cap, in which the side plate 20 has a triangular shape, no guide surface, and
The point that the width of the second locking pieces 30 and 31 is large is different from the corner cap of the second embodiment. When the gasket 2 is mounted with the corner cap 4 mounted, the concave groove 14 of the gasket 2 does not fit into the main body 22 and the width of the gasket 2 is expanded by pushing and expanding. Nothing. Thereby, the glass 1 on which the corner cap 4 and the gasket 2 are attached can be easily mounted in the concave groove of the sash frame member. The first locking piece 3 of the corner cap 4
Since the second locking piece 31 is pressed against the end surface of the glass 1 at the bottom of the concave groove 14 of the gasket 2, the corner cap 4 can be supported by the gasket 2 so as not to come off.
Thereby, the corner cap 4 does not come off when carrying the glass on which the gasket 2 and the corner cap 4 are attached. Further, since the outer surface of the back plate 21 of the main body 22 projects beyond the outer surface of the gasket 2, the outer surface of the back plate 21 of the main body 22 is grounded when the glass 1 on which the gasket 2 and the corner cap 4 are mounted is leaned. Gasket 2 is not grounded. This prevents the gasket 2 from being broken when the glass 1 is transported and stored with the glass 1 upright.
