TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pool floor installed in a pool so as to be able to move up and down.
[0002]
[Prior art]
1 shows an example of the pool floor 1, FIG. 2 is an enlarged view of FIG. 1a, FIG. 3 is a sectional view taken along line AA of FIG. 2, FIG. 4 is a sectional view taken along line BB of FIG. It is the same CC section.
The pool floor 1 shown in FIG. 1 has, as shown in FIGS. 2 to 5, a frame 2 having a groove shape in cross section, and a floor material 3 having a constant gap c perpendicular to the frame 2. As shown in FIGS. 4 and 5, the flooring material 3 has a left-right symmetrical shape, and the interior is partitioned by vertical ribs 4 to form a plurality of air chambers 5. Thus, the pool floor 1 is made to have buoyancy, and the chambers 6 on both sides have a groove 7 formed in the center of the lower surface in the longitudinal direction of the floor material 3.
[0003]
To assemble the pool floor 1, a thin plate-like connecting metal fitting 8 in which floor materials 3 are arranged on a frame 2 arranged side by side at right angles to the frame 2 and bolt holes are formed at a constant pitch from the lower surface of the floor material between the frames. , And the bolts 9 of the bolts 9 passed through the chambers 6 pass through the bolt holes of the connection fittings 8 through the projecting portions from the grooves 7, and the nuts 11 are screwed into the projecting portions to fasten the flooring 3. 3 and 4, the lower surface of the chamber 6 and the upper surface of the frame are sandwiched between the lower surface of the chamber 6 and the upper surface of the frame by the clamp 12 and the presser 13 which pass through the chamber 6 as shown in FIGS. And the nut 15.
[0004]
[Problems to be solved by the invention]
In the conventional pool floor described above,
(1) The reason for arranging the floor materials with a certain gap c is to reduce the resistance of water during the ascent and descent by allowing water to enter and exit through the gap c when moving up and down the pool floor 1. However, a tie 8 is required for this purpose. To connect the floor 3 to the tie 8, a necessary number of bolts 9 are inserted into the chamber 6 from the end of the floor 3 through the groove 7, and The nut 11 needs to be screwed into the bolt projecting end from the bolt 7 through the bolt through hole of the connection fitting 8 and fastened;
(2) The flooring material 3 needs to be connected to the frame 2 using bolts and nuts by sandwiching the lower surface of the room and the upper surface of the frame with the frame 12 in the left and right rooms 6 in the frame 6.
(3) Even if the pool floor 1 is raised and lowered, the water in the left and right chambers 6 is not easily exchanged, and the water tends to stagnate and become dirty. It is necessary to spray water into the chamber 6 from below the floor 1 and cleaning is not easy;
And so on.
An object of the present invention is to provide a pool floor that solves the above-mentioned problems.
[0005]
[Means for solving the problem]
The pool floor according to the first aspect of the present invention is capable of ascending and descending into a pool formed by arranging floor materials provided with air chambers on a frame arranged side by side at right angles to the frame and connecting the frame to the frame via fastening means. In the pool floor installed on the floor, the flooring has a flange protruding laterally at the lower end of each side surface, the fastening means has bolts, and the flooring material adjacent on both sides of the head of the bolt The flanges facing each other are pressed and fixed.
[0006]
According to the pool floor of the present invention,
(1) The opposing flanges of adjacent flooring materials can be pressed and fixed simultaneously with their heads using a single bolt, and each flooring material, except the flooring material at both ends of the pool floor, is Can be fixed with bolts,
(2) It is not necessary to form a chamber having a groove for passing bolts, and the air chamber can be widened accordingly, so that buoyancy can be increased, and even a compact flooring can have the same buoyancy.
(3) There is no room for water to enter the flooring material, and there is no need for water to become dirty or to be washed.
The flooring material of the present invention may be made of metal such as aluminum, but is preferably made of inexpensive plastic, and is obtained by extrusion molding.
[0007]
The invention according to claim 2 is characterized in that, in the invention according to claim 1, the shaft portion of the bolt is fixed by sandwiching the shaft portion of the bolt between opposing flanges of the adjacent floor material. It is characterized in that the bolt head is sandwiched and fixed between opposing side surfaces of the material.
According to each of the above inventions, a fixed gap can be formed between the floor materials by the bolts for fixing the floor materials.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
The flooring 21 shown in FIG. 6 is partitioned by longitudinal ribs 22 provided at equal intervals in the inside to form three air chambers 23 of the same shape and the same size, and lounges 24 and 25 are provided on the upper and lower sides on both sides. When connected to the frame 2, the floor members 21 are arranged on the frame 2 by using the stoppers 12 and the holding members 13, as shown in FIGS. The stopper metal 12 is placed on the upper surface, the bolt 14 is passed through between the holding metal member 13 and the holding member 13 applied to the upper surface of the frame from below, and the floor material 21 on both sides is pushed until the flange 25 hits the bolt shaft portion. A nut 15 is screwed into the protruding end and fixed. In this way, the floor members 21 are sequentially arranged on the frame 2, and a fixed gap 26 is formed between the flanges 24 by the bolt shaft portion.
[0009]
According to the flooring material 21 of the present embodiment, each flooring material 21 is fixed by one bolt 14, nut 15, stopper 12, and holding metal 13, excluding the flooring material at both ends of the pool floor. Compared to the flooring 3 shown in FIG. 4, the air chamber 5 is expanded and the buoyancy can be increased by the absence of the chamber 6 for passing the bolts 9 and 14, so that the flooring for obtaining the required buoyancy is made compact. That is, a fixed gap 26 can be formed between the floor materials with bolts for fixing the floor material, and a tie 8 for forming the certain gap 26 between the floor materials, and the floor with the tie 8 The work to form a certain gap between the materials can be unnecessary, there is no room that becomes dirty due to water entering, and there is no room that makes cleaning difficult. It can be easily done by spraying water Rukoto, longitudinal ribs 22 are provided at regular intervals, an effect such that it is possible to equalize the intensity of the flooring 21.
[0010]
The floor material 28 shown in FIG. 7 is formed such that the side surface thereof is cut downward so that the head of the bolt 14 fits on the flange 31 of the cutout portion 29. In the same manner, using the stopper 12 and the holding member 13, the bolt 14 and the nut 15 are used to connect the frame 2 to the frame 2, and a gap 30 is formed between the floor materials 28.
[0011]
【The invention's effect】
According to the invention according to claim 1, each floor material can be fixed by one bolt, except for the floor surface on both sides of the pool floor, and the number of fixing tools and fixing work can be reduced by half compared with the conventional one. Since there is no room for bolts, the air chamber can be made large and the buoyancy increases, so the floor material for obtaining the required buoyancy can be made compact. Although there is a problem that the water that has entered has become stagnant and dirty, and it is not easy to clean, there is an effect that such a problem does not occur because there is no room into which water enters.
[0012]
According to the inventions according to Claims 2 and 3, a fixed gap can be formed between the flooring materials at the same time by the bolts for fixing the flooring material, and a conventional tie or a work for fixing the tie can be performed. Can be eliminated.
