Description

[Detailed Description of the Invention] The present invention relates to glazing for covering an overflow drain formed in the deck portion of an assembled swimming pool.

Conventionally, this type of glazing cannot be expanded or contracted because it is made of materials such as FRP or iron and is integrally molded. Therefore, in order to reliably cover the entire length of drainage ditches of various desired lengths, it is necessary to manufacture glazing with different overall lengths.
For this purpose, it is necessary to prepare several types of complicated molds, which has the disadvantage of increasing manufacturing costs and complicating manufacturing operations.

The present invention was developed in view of the above-mentioned conventional circumstances, and its purpose is to be able to freely change the length by combining a leg resting rod and a joint material, and to enable the use of complex molds. The purpose is to provide glazing that does not require the preparation of several types and does not cause an increase in manufacturing costs.

The basic structure for achieving this purpose is to form connecting receptacles along the longitudinal direction of both sides of the leg rests, and to connect the joint material across the opposing connecting receptacles of the leg rests. It is possible to freely change the length by engaging the parts so that they can be taken in and taken out.

Embodiments of the present invention will be described below with reference to the drawings.

The leg rest A has a length long enough to vertically traverse the overflow drainage groove 3 formed in the deck part 2 of the assembled pool 1, and has a connecting receiving part a at approximately the middle part of both sides. It is made of synthetic resin such as vinyl chloride or polyethylene and is formed into a hollow shape by a desired method such as extrusion molding.

The connection receiving part a is for supporting the joint material B that connects the adjacent leg rests A and A, and has a narrow width shape as shown in Figs. 3, 5, and 6. It consists of a slip-out prevention groove _A1 and a spherical, triangular, or square fitting groove _A2 communicating with the groove _A1 , and is formed over the entire length in the longitudinal direction on both sides of the leg rest A. .

The joint material B is used to connect the leg rests A and A, and is made of synthetic resin such as vinyl chloride or polyethylene, and has fitting parts b on both ends that fit into the connection receiving parts a. Form it into a strip shape with the same length as the leg rest A.

As shown in FIGS. 3, 5, and 6, the fitted portion b is a spherical, triangular, or quadrangular protrusion _b1 having a similar shape that is slightly smaller than the fitting groove _a2 , and is a joint. Formed along the entire length of both ends of material B or at appropriate intervals.

Therefore, the joint material B is inserted from the longitudinal direction across the connection receiving parts a, a of the adjacent leg rests A, A.
, and repeat this process one after another to form the desired length of glazing. At this time, the joint material B is prevented from disengaging from the mating part b by the slip-off prevention groove _a1 of the connection receiving part a, so once it is inserted, the leg rests A and A are connected to each other. maintain.

In addition, in the connection structure between the connection receiving part a and the joint material B, even if the receiving part a is not formed into a groove and the joint material B is not formed into a protrusion, the joint material B
While a slip-out prevention groove _a1 and a fitting groove _a2 are formed in the groove, the connecting receiving part a may be formed as a protrusion _b1 that engages with the grooves _a1 and _a2 .

In addition, C is a lid body that removably covers the openings at both ends _of the leg rest A to prevent the joint material B from falling out in _the longitudinal direction. It is formed with a claw piece _c2 that projects and engages the inner surface of the leg rest A.

Incidentally, the glazing shown in FIGS. 3, 5, and 6 also has the advantage of being able to be rolled up when stored in a warehouse, pool equipment storage, or the like.

When storing glazing in a rolled form to reduce the occupied area, the ones in Figures 3 and 5 make it possible to form a certain range of the entire length of the middle part of joint material B and the joint material B itself from soft PVC or soft polyethylene. In the case of the one shown in FIG. 6, the part directly above the connection receiving part a is made of soft vinyl chloride or soft polyethylene, so that it can be rolled up and stored.

In addition, these glazings are made by forming an anti-slip part 4 made of soft resin with several recesses 4' such as chevron strips on the upper surface of the leg rest A, and on the lower surface of the leg rest A to stably place the leg rest A in the drain groove 3. A seat portion 5 made of soft resin is formed to expand the placement area for placing the device. Note that 6 is a drainage passage.

As described above, the present invention forms connection receiving portions along the longitudinal direction of both side surfaces of the leg resting rods, and allows the joint material to be freely inserted and taken out by crossing the connecting receiving portions facing each other between the leg resting rods. Since they are combined, a desired length of glazing can be formed. Therefore, there is no need to mold several types of glazing with different overall lengths using FRP, iron, etc., making it inexpensive and extremely convenient.

Thus, the intended purpose can be achieved.
