Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a simple stationary swimming pool.

Recently, simple stationary pools have been used that are installed in the gardens of kindergartens and nursery schools and are used only during the summer.
Its structure is made of a molded product made of fiber-reinforced plastic, with a sanderch structure and many reinforcing materials to improve rigidity. As a result, the weight of the product increases, making it inconvenient to handle and increasing manufacturing costs.

The present invention was made in order to eliminate these conventional drawbacks, and provides a pool that is lightweight and has excellent strength. That is,
This invention provides a simple stationary swimming pool installed on the ground, in which end segments constituting both ends of the pool and an intermediate segment formed integrally with a bottom plate and both side plates are attached to and detached from each other at their ends. The side panels are butt-jointed so that the pool can be butt-jointed, and the above-mentioned side panels are curved outward or inward in a plan view when viewed from above in the assembled state of the pool, whereby the side panels themselves exert a reinforcing effect to reduce the weight of the segment. It is designed to be easily transported and manufactured at low cost.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, in which a pool 1 has end segments 2, 3 and intermediate segments 4, 4 made of fiber reinforced plastic.
a, 4b, 4c, and 4d are connected to each other, and a step 19 is installed at one end thereof.
As shown in FIGS. 2 and 3, the end segment 2 is formed by integrally forming a bottom plate 21, both side plates 22, and an end side plate 23, and a flange perpendicular to the bottom plate 21 and the side plates 22 is provided at the end on the joining side. 26 and a flange 25 are formed. By forming the flanges 25, 26 orthogonally to the bottom plate 21 and the side plates 22, the connecting means also serve as a reinforcing member, eliminating the need for special reinforcing members. In particular, when the segments are joined to each other, the flanges rise and become reinforcing bones of the pool, which has the effect of increasing the local and overall rigidity of the pool. Note that the bottom plate 21 and the side plates 22 are inclined at 104° in the example shown, but this angle θ is
It may be set within the range of 100 to 110°. Below this range, the side plates will interfere with each other during stacking, which will be described later, and above this range, it is unfavorable in terms of appearance and strength. A rib 29 extending in the vertical direction is formed on the end side plate 23, and this may be formed, for example, as follows. That is, when molding a product by mixing glass fiber and polyester resin and laminating them in a mold, it is sufficient to mold the product using a mold in which the ribs 29 are formed to protrude outward. Rib 29 is formed at the same time as the product is formed.
is formed integrally with the end side plate 23. The end side plates are reinforced by the ribs 29. Further, the ribs 29 are prevented from protruding inward so that they do not interfere with swimming in the pool. Furthermore, a recess 28 for connection, which will be described later, is formed at the joining side end of the segment.

As shown in FIGS. 4 and 5, the end segment 3 is formed by integrally forming a bottom plate 31, both side plates 32, and an end side plate 33, and a step 39 protruding inward is formed in the center of the end side plate 33. ing. The other shapes are substantially the same as the end segment 2. In addition,
When the end segments 2 and 3 are formed integrally with the end side plates, both side plates, and the bottom plate as described above, there is an advantage that the mutual members reinforce each other and increase the rigidity of the whole. It is not necessary to form two or more divided pieces, and two or more divided pieces may be combined.

As shown in FIGS. 6, 7, 8, and 9, the intermediate segment 4 is formed by integrally forming a bottom plate 41 and both side plates 42, and flanges 45 and 46 for joining are formed on both sides of the bottom plate 41 and the above-mentioned recess. A recess 28 corresponding to 28 is formed. Further, the side plate 42 is formed to be curved outward in a plan view when viewed from above in the pool assembled state, and the width A of this curved portion is set to a constant value smaller than the width B of the segment. By curving the side plates in this way,
The rigidity of the side plate itself has been increased to make it less susceptible to bending due to the force exerted by the pool water. In addition, because the rigidity is simply increased by curving the side panels, the weight of the pool is smaller compared to cases where reinforcing members are attached separately or the thickness of the panels is increased, and manufacturing costs can also be reduced. can.
In addition, although the example in the figure shows an example of curving outward,
Of course, it may be curved inward. Furthermore, by making the width A of the curved surface constant for all segments, it is possible to prevent the side plates from interfering with each other during stacking, which will be described later. Furthermore, side plate 4
2 is formed into a substantially spherical shape by curving it in the vertical direction as well. This cubic curved surface has the effect of making the horizontally curved surface difficult to deform, and by curving in both directions, sufficient rigidity can be exhibited with a thin wall.

The bottom plate 41 is made up of a core material 55 such as a foamed material covered with an outer skin 44 made of fiber-reinforced plastic, and both ends are formed such that one protrudes in a V-shape and the other is recessed in a V-shape. The portion 47 is configured to fit together with the packing 10 interposed therebetween. The concave portion 48 and the convex portion 47 are formed continuously along the flanges 45 and 46 as shown in FIGS. 10 and 11, and FIGS.
Figures A and B show the convex portions 47, respectively. Lines C and D indicate the shapes of the concave portion 48 and the convex portion 47, respectively. Also, the side plate 4 that forms the edge of the pool
A projecting edge 50 is formed on the upper end surface 5 of 2. This upper end surface needs to extend to some extent from the upper end of the side plate in order to strengthen the upper edge of the pool and improve its overall rigidity, but if it is extended on a flat surface, it will be easier for people to stand on it. Become. However, since it is installed in a garden or the like, it is dangerous for young children to ride on it, and for this reason, a protrusion has been formed to make it difficult to climb on and to meet the demand for improved rigidity. Middle segment 4a, 4b, 4
The structures of segments c and 4d are the same as that of segment 4, but the width A is constant and only the width B is different because of stacking, which will be described later. 12 to 14 show the structure of the joint, in which the recess 28 is formed in the shape of a semi-disk, onto which the fixing members 6 and 7 are respectively fixed by screws or the like. The fixing member 6 is formed by protruding a second locking part 62 from a semi-disc-shaped substrate 61, and the fixing member 7 is formed by forming a first locking part 73 through a wall 72 rising from the substrate 71. A center hole 74 is formed in the first locking portion 73 . The fastening fitting 9 has a protrusion 91 serving as a central axis on one side of a disc 90 and a third locking part 92 on an arc centered on the protrusion 91.
and a spiral fourth locking portion 93 are formed, respectively, and each of the locking portions 92 and 93 has a tip end bent toward the center.

To perform this connection, as shown in FIG. 14A, the concave portions 28 are placed opposite each other and close to each other, and the fastening metal fitting 9 is attached from above by fitting its protrusion 91 into the center hole 74. When the disk 90 is rotated in the direction of the arrow from this state, the third locking portion 9
2 meshes with the first locking part 73, and the fourth locking part 93 meshes with the second locking part 62, and since the fourth locking part 93 is formed in a spiral shape, the second locking part 62 As a result, both segments come into contact with each other as shown in FIG. 14B.
Further, the third locking portion 92 and the fourth locking portion 93 have their tip portions bent toward the center, so that they are prevented from coming off, and the connected state is maintained firmly. Note that in order to rotate the fastening metal fitting 9, a concave portion may be formed on the upper surface of the disk 90, and a suitable jig may be fitted into the concave portion to rotate the concave portion. Moreover, to remove the connection, the fastening metal fittings may be rotated in the opposite direction to that described above.

Figure 15 shows examples in which the size of the pool is varied; A and B use five intermediate segments;
Ha, D are 4 pieces, Ho, He is 3 pieces, G, Chi are 2 pieces,
R and N respectively show examples using one. In this way, the size of the pool can be freely set depending on the number of intermediate segments.
This is extremely convenient for kindergartens and other facilities, as the size of the pool can be arbitrarily set according to the increase or decrease in the number of children. In particular, when increasing the size, it is only necessary to purchase an additional intermediate segment, which is very advantageous in terms of cost.

FIG. 16 shows an example in which the shape of the pool is changed in various ways. The connecting surfaces at both ends of the intermediate segment 40 are formed non-parallel to each other, so that the combination of the segments can change not only the size but also the shape of the pool. can be freely selected according to the user's preference. In addition, the back shapes of the side plates of the end segments 20, 30 and the intermediate segment 40 are curved so that the shapes can also be changed.

FIG. 17 shows the state in which the pool is disassembled and stored. As shown in FIG. 17, a person holds both sides of the middle segment and stacks them one by one. At this time, the bottom plates 41 are stacked in contact with each other, and each segment is stacked in order from the narrowest to the flange 4.
5 and 46 are stacked so as not to touch each other.
After stacking the middle segments, the 18th, 1st
Stack the end segments 2, 3 and step 19 as shown in Figures 9 and 20. The side plates of each segment are formed with an appropriate inclination, and the bottom plate is formed thicker than the side plates, and the horizontal curved surfaces have the same width, so that they do not come into contact with each other when stacked. There is. Therefore, there is no risk of deformation even if they are stacked for a long period of time, and they can be easily taken out.

As explained above, this invention achieves improved rigidity without increasing weight by integrally forming the bottom plate and both side plates and curving both sides outward or inward in a horizontal plane. This makes it possible to omit or significantly reduce the conventionally used sanderch structure and many reinforcing materials, thereby reducing weight and cost. In addition, in order to enhance the reinforcing effect due to the above-mentioned curvature, it is more effective to curve it in the vertical direction as well.

Further, by integrally forming flanges at the ends of the segments, the reinforcing effect of the segments alone and of the pool as a whole can be exerted by means of joining between the segments.

Further, by integrally forming the end side plate, both side plates, and the bottom plate, the end segment can be made into a lightweight and highly rigid segment due to the mutual reinforcing effect of each member. Furthermore, by making the side walls project outward to form ribs, the walls can be reinforced without becoming an obstruction within the pool.

Further, by forming a protrusion on the upper end of the side plate, it is possible to prevent people from getting on the protrusion while achieving a reinforcing effect as an edge material of the pool.

Furthermore, by making both ends of the intermediate segments parallel to each other, the size of the rectangular pool can be arbitrarily selected by increasing or decreasing the number of segments, and by making the ends of the middle segments non-parallel to each other. This has the advantage that the shape of the pool can be changed arbitrarily.
