Description

[Detailed description of the invention] [Field of application of the invention] This invention is a pool opening that can be easily opened, removed, and covered so that the upper surface of a swimming pool can be covered when not in use and used for other sports, games, etc. This relates to a surface covering structure.

[Prior Art] Swimming pools, especially outdoor pools, are not used except during the best swimming season, and their space is wasted. Therefore, in order to make effective use of this space, the water in the pool is drained, but in this case, there is a risk that cracks may occur in the inner walls, bottom surface, etc. of the pool, resulting in damage to the pool.

Another method is to cover the top surface of the pool in order to make effective use of the pool space, but this method consists of installing height-adjustable supports in the pool, providing braces between the supports, and turning the pool into turnbuckles. A method in which a plurality of beams are stretched horizontally on top of the beam, and treads, mats, etc. are placed and stretched on top of the beam, or a bottomless box is placed on the surface of the pool water and the box is Styrofoam was connected inside the box, and its buoyancy was used to support footboards and the like placed on the top of the box.

[Problems that the invention aims to solve] As mentioned above, there were some methods that used the top surface of the pool, but those that installed supports in the water were difficult to use because the bottom of the pool is sloped. Construction is difficult, and since metal is used due to strength issues, it is prone to corrosion and rust.Furthermore, the above-mentioned supports are extremely troublesome and time-consuming to store and temporarily remove when not in use. There were problems such as the need for rust prevention treatment.

In addition, in the case of pools that utilize buoyancy, the supporting force of the central part of the pool is unstable due to the shaking of the water, etc., and the pool tends to move up and down due to the movement of people on the top surface of the pool, and it is difficult to connect and remove Styrofoam. There were problems such as the removal being very troublesome.

[Means for Solving the Problem] This invention was provided in order to eliminate the above problems, in which rails are arranged in parallel on both sides of the pool in the longitudinal direction, and a plurality of beams are placed on the rails at both ends. A movable beam is horizontally supported by rolls installed on the floor, and each beam is telescopically connected at predetermined intervals by wires, links, etc., and a treadle is laid on the extended movable beam. The movable beam has a rear end fixed to one side of the pool, a sprocket on both sides of the tip driven by a motor mounted on the beam, and a sprocket that is wound around the sprocket and connected to the rail. This is a covering structure for the pool opening surface in which the movable beam is extended and contracted over the pool opening surface by moving the tip part according to a chain stretched parallel to the pool, and it is very easy to cover and open the pool opening surface. This is what I did.

[Example] A typical example of this invention will be described below with reference to the drawings.

Reference numeral 1 denotes a movable beam, and numeral 2 denotes a step board. The movable beam 1 is extended over the opening surface of the pool 3, and the step boards 2 are spread over it to cover it.

Reference numerals 4 and 4 denote rails whose bases are embedded and fixed in parallel to both sides of the pool 3 in the longitudinal direction, and a plurality of beams 5 constituting movable beams are horizontally mounted on the rails 4. The beams 5 are made movable by the rolls 6, 6 provided at both ends of the beams 5 rotating on the rails 4, and each beam 5 is configured such that one end thereof slides along the beams 5. They are telescopically connected at a predetermined interval 1 by links 7 configured as shown in FIG.

The movable beam 1 has a rear end 1b fixed to one side of the pool 3 by bolting or the like, and sprockets 9, 9 fixed to a shaft 8 supported in the length direction of the beam 5 at both ends of the tip 1a. The shaft 8 is rotated by a motor M mounted on the top end 1a of the movable beam 1, and the pool 3 has a chain 1 parallel to the rails 4, 4, respectively.
0 and 10 are stretched, and the chains 10 and 10 are wound around the sprockets 9 and 9 of the movable beam 1. 9' is a tension sprocket. There is also a method of connecting each beam 5 by fixing it to a wire at a predetermined interval l without using the link 7, and expanding and contracting the interval l by winding the wire.

In addition, the tread 2 is made by laying panels 2a of a unit width for construction between the beams 5 and securing them with screws, or as shown in FIG. In addition, the long plates 2b having the same width as the interval l between the beams 5 are connected with hinges 11 or the like so that they can be bent up and down alternately, and only the tip and rear ends are connected to the tip of the movable beam 1. 1a
It may be fixed to the rear end portion 1b so that it can be expanded and folded as the movable beam expands and contracts.

[Function] When the opening surface of the pool 3 is to be covered, if the motor M is driven, the sprockets 9, 9 will move the end portion 1a of the movable beam 1 along the chains 10, 10.
moves forward on the rails 4, 4, and the beams 5 connected by the links 7 are pulled out while widening the interval to 1, and are disposed on the entire opening surface of the pool 3. Further, the panels 2a are laid and locked on top of the panels 2a, and mats, plates, etc. are laid on top of the panels 2a, so that it can be arranged according to the type of sport or the like.

Regarding removal, the movable beams 1 are compressed by operations and actions in the reverse order to those described above, and each beam 5 is stored in close contact with one side of the pool 3, and the entire opening surface of the pool 3 is left open. . Usually, a storage section is provided under the starting platform of the pool 3, and the movable beam has no exposed part.

Incidentally, when the movable beam 1 is compressed, the tread plate 2, which is made up of a long plate 2b that can be bent by hinges 11 etc. shown in FIG. This is possible, and when the movable beam 1 is extended, the footboard 2 also extends along with the extension, and can be laid on the movable beam 1.

[Effects] Since this invention is constructed as described above, it is very easy to cover or open the opening surface of the pool when it is not in use. Removal is done automatically by simply operating a motor, and the beams are stored at one end of the pool, which greatly reduces the number of workers required, and there is no need to drain the pool for work. , it is possible to save unnecessary expenses due to water injection.

In addition, since there is nothing to be installed or immersed in water, there is no fear of rust, and it can be used for a long period of time without contaminating the water.

Furthermore, since no load is applied to the bottom of the pool or the like, and the load is applied only to the rails, there is no damage to the pool.

Furthermore, due to the above structure, the number of parts is small and the cost is low.
