Description

[Detailed description of the invention] (Industrial application field) This invention is used for corners that stand upright as mullions at the corners of bay windows and partitions, and are used to elastically support shielding plates such as glass plates. Regarding gaskets.

(Prior Art) A gasket of this type is known from Japanese Utility Model Application Publication No. 10830/1983. The gasket body according to the invention in this publication has wing sections extending to the left and right at both ends of the core section, intersecting fitting grooves formed on both wing sections on both sides of the core section, and intersecting grooves formed on both wing sections of the core section. Beat grooves are provided approximately at the center and at an offset position on one side. When fitting a shielding plate such as a glass plate into this gasket body, it is easy to fit it into the side having the bead grooves provided on one side, but it becomes difficult to fit it into the other fitting groove. Furthermore, when installing a gasket in a corner of a bay window, etc., after attaching a gasket to one shielding plate, the other shielding plate can be fitted from the outdoor side, but in this case, one wing part of the gasket body must be bent to fit. It is necessary to open the groove so that the bottom surface is completely exposed and can be seen from outside, but the above-mentioned design cannot open it wide, making it difficult to fit the shielding plate from outside.

(Purpose of the invention) This invention allows the gasket body to be easily attached to one shielding plate, the other shielding plate to be easily fitted from the outdoor side, and furthermore, the shielding plates do not shift after each shielding plate is installed. To provide a corner zipper gasket which can be securely fastened without any trouble.

(Structure of the invention) The corner zipper gasket according to this invention has wing parts extending left and right at opposite ends of the core part, and shielding plate engagement grooves intersect with each other on both sides of the core part at both wing parts. A zipper groove is provided on the left and right sides of the outer edge of one of the wing parts, respectively, so as to straddle an imaginary line extending from the bottom surface of each shielding plate engagement groove, and It is characterized in that a notch is provided closer to the wing portion where the zipper groove is provided than the bottom surface of the engagement groove.

(Embodiment) As shown in Fig. 1, the gasket body 1 consists of a gasket body 1 and a pair of zippers 2 and 3.
In this example, wing parts 5 and 6 extending to the left and right of the core part 4 are provided at the top and the bottom of the core part 4 which is long in the shape of a string and has a substantially triangular shape, respectively. Shielding plates 16 made of double glass on both sides of the core 4,
The shielding plate engaging grooves 7 and 8 into which the shielding plate 17 is fitted are formed to intersect with each other. For this gasket body 1, zipper grooves 11 and 12 are respectively extended from the bottom surfaces 9 and 10 of the shielding plate engagement grooves 7 and 8 on the left and right sides of one of the wing parts 5, which will be on the outdoor side when installed in a bay window. virtual line 1
Furthermore, a notch 15 is provided closer to the zipper groove 12 than the bottom surface 10 of either the left or right, and the length protruding from the core 4 of the wing 5 is set to the other side. It is made longer.

In the example shown in FIGS. 3 and 4, a pair of zippers 2 and 3 are integrally connected by a connecting plate 18, and the structure of the gasket body 1 is the same as that described above.

According to the above embodiment, the portion of one wing portion 5 on the right side in the figure where only the zipper groove 11 is provided is bent outward at the zipper groove 11, and one shielding plate 16 is fitted into the shielding plate engagement groove 7, After fitting, the folded portion is returned to its normal position and the shielding plate 16 is clamped, and then the zipper 12 is inserted into the zipper groove 11 of the portion and fixed. Next, when supporting the shielding plate 17 on the left side in the figure, as shown in FIG. Therefore, the portion corresponding to the notch portion 15 is also bent outward. Due to this bending, the shielding plate engagement groove 8 is widened, and the groove 8
Since the bottom surface 10 of the shielding plate 17 is completely exposed, the shielding plate 17
toward the mating wing portion 6 from a direction perpendicular to the original opening direction of the shielding plate engagement groove 8, and then,
The bent portion is returned to its original position and the zipper 3 is fitted.

(Effect of the invention) The zipper gasket for corners according to this invention has a gasket main body in which shielding plate engagement grooves are provided intersectingly on both sides of the core part, and the zipper gasket is provided in the left and right parts of the wing part extending to the left and right on one side, respectively. The zipper groove is provided so as to straddle an imaginary line extending from the bottom of the shielding plate engaging groove, and a notch is provided closer to the corresponding zipper groove than the bottom of one of the shielding plate engaging grooves. As mentioned above, each zipper groove is provided across the imaginary line, so the end of the wing can be easily bent and the shielding plate can be firmly supported when the zipper is inserted. be. Furthermore, when one shielding plate is supported and another shielding plate is fitted, the previously supported shielding plate does not shift or come off, and the shielding plate engagement groove can be opened sufficiently wide. . Moreover, since the shielding plate engaging groove, which is fitted later, has a notch,
Since the groove can be opened wide, the fitting operation from the outside can be easily and accurately supported.
