Description

  The present invention relates to a pool floor which is submerged in a pool and used to reduce the depth of the pool, and more particularly to a pool floor having a rubber mat on the upper surface thereof.

  The pool floor is submerged in the pool to reduce its depth, so that a part of the adult pool can be used for children, or for people with back pain or weak people to train It is used when forming a place for "underwater walking", and the applicant has also proposed various things.

  When children play with water or perform underwater walking on such a pool floor, the upper surface of the pool floor needs to be hard to slip. Therefore, in the conventional pool floor, it has been made to form unevenness on the surface of the top plate and make it difficult to slip by this unevenness, but this kind of pool floor is made of synthetic resin. In many cases, the size of the unevenness is an important issue.

  That is, if the unevenness is small, it may be suitable for children, but it is not suitable for underwater walking for adults. Conversely, if the unevenness is large, it is good for adults, but there are problems such as painful feet for children.

Therefore, as a result of repeated investigations by the present inventors as to whether there is any slipper that can be used for this type of pool floor, a “walking mat” as described in Patent Document 1 was found. It was.
JP 2002-227440 A, summary, representative diagram

  According to the summary description, the mat shown in Patent Document 1 “provides a set of mats for walking underwater and connecting hooks that can be firmly connected to each other and can be easily assembled and disassembled in the field”. For the purpose, as shown in FIG. 13, “The walking mat 10 has a groove 11 formed on the peripheral edge of the lower surface, a through hole 12 formed on a portion of the upper surface facing the groove 11, and a foot on substantially the entire upper surface. The projections 13 and 14 for stimulating the acupuncture points on the back of the mat are formed and have a specific gravity of 1 or more. The projections 22 and 23 are inserted into the through holes 12 when connected, and the projections 22 and 23 have the same shape as the projections 13 and 14 formed on the mat 10, and in the connected state, the projections 22 and 23 The mating head protrudes from the top surface of the mat 10 to increase the connection strength, When used, it acts as a protrusion for stimulating the acupoints on the soles of the feet. Many mats 10 are connected by connecting hooks 20 and laid on the bottom of the swimming pool to be used when walking underwater. It is.

  This mat is certainly "laying on the bottom of the swimming pool and used when walking underwater", but the water depth in the pool cannot be adjusted, and it can only be used in a deep pool. I can't do it.

  Further, when the mat of Patent Document 1 is used on a pool floor, the following problems are considered to occur. In other words, the use of the pool must counter the flow of water in the pool and must be stably fixed to the floor of the pool. It is thought that it cannot resist the flow of water.

  Therefore, as a result of various investigations on how to make the pool floor to be used underwater not only adjust the water depth but also to make it stable and resistant to slipping, the present inventors have made the present invention. Was completed.

That, or not a, it is an the onset bright object is to perform the depth adjustment, of course, is to provide a pool floor that can slip even if the vigorous movement in its upper surface with a simple structure .

Also, it is an the onset Ming purpose, in addition to the above, or to ensure the slip in use, or by less susceptible to the influence of the water flow, so that the rubber mat 20 is stable at the top plate on the The object is to provide a pool floor 10 that is made up of.

Furthermore, it is an the onset bright object, in addition to the state, and are to be able to further stabilize the rubber mat 20 by di Yointo 30, attachment of di Yointo 30 and removal operation is to easily perform such, element is to prevent the rattling of the joint 30 fitted with a rubber Mumatto 20 to the pool floor 10.

In order to solve the above problems, or not a means of adopting the present onset Ming is explained with reference numeral used in the description of the best mode described below,
“A pool floor 10 that is submerged in the pool and used to reduce the depth of this pool,
The pool floor 10 is characterized in that a rubber mat 20 is laid on the top plate 11 of the pool floor 10 and the side edges of the rubber mat 20 are fixed to the side edges of the pool floor 10 by joints 30 ".
It is.

That is, up Rufuroa 10 of this, as shown in FIG. 1, which has laid the rubber mat 20 on the top plate 11 constituting the pool floor 10 made of a synthetic resin, the depth of the pool by the top plate 11 In addition to adjusting the height, the rubber mat 20 on the top serves to “slip” when, for example, children play with water or walk underwater for people with weak bodies.

  Since this pool floor 10 has a rubber mat 20 laid thereon, it is not necessary to apply a special anti-slip process to the top plate 11 of the pool floor 10, and the rubber mat 20 can be used for adults or By selecting as appropriate for children, or just for playing in water or walking underwater, the selected rubber mat 20 may be used while the pool floor 10 is used as it is.

Of course, rubber mat 20, since only the fixed joint 30 to be described later have laid on the top plate 11 of the pool floor 10 is than attached and detached relative to the pool floor 10 can be performed easily, using the pool floor 10 It is easy to clean up when not.

Therefore, up Rufuroa 10 This is first not only allows the depth adjustment of the depth of the pool can be the rubber mat 20 thereon, exerts a slip effect during use of the pool floor 10 It is.

Incidentally, what is with the pool floor 10 of this, the rubber Mumatto 20, comprising at least one of the integrally multiple projections 22 are formed or drain hole 23 formed in the base portion 21, at its base 21 the upper surface It can also be .

That is, up Rufuroa 10 of this, as shown in FIGS. 2 to 4, the rubber mat 20 laid thereon, a number of projections 22 are formed integrally with the base portion 21 an upper surface or drain which is formed in the base 21, There it is possible to also assumed having at least one of the holes 23, the case of forming only the protrusion 22, when forming only the drain hole 23, and includes both projections 22 and drain hole 23 There is a case.

  In the case of the best mode to be described later, each projection 22 is of two types, large and small, as shown in FIGS. 2 and 3, and by forming a large number of these projections 22, it can be used by children and adults. The number hits the soles is increased. Thus, the anti-slip effect is enhanced by the protrusions 22 and the protrusions 22 are prevented from being painful even if they hit the soles. Of course, these protrusions 22 also serve to massage the soles of people who play games or walk underwater.

  Each drain hole 23 is made so that the rubber mat 20 is not affected by the water flow, but as shown in FIGS. When the rubber mat 20 is placed on the top plate 11 of the pool floor 10, the corresponding part of the top plate 11 is exposed. In other words, each drain hole 23 allows not only the water in the pool to easily flow through it, but also the discharge of the water that has once flowed into the pool can be easily performed by the weight of the rubber mat 20. .

  In other words, the rubber mat 20 is positioned on the top plate 11 of the pool floor 10 in a stable state with little influence from the water flow in the pool due to the respective drain holes 23. When playing on the water or walking under the water, there is no sense of incongruity and it does not get tangled in the foot.

Therefore, up Rufuroa 10 This is the case of the one having at least one of the integrally multiple projections 22 are formed or drain hole 23 formed in the base 21, the base 21 top surface is used or to ensure slip in, or by less susceptible to water, there can be the the even rubber mat 20 is stabilized at the top plate 11 above.

Then, this preference Rufuro A 10,
"To fixed to the side edges of the pool floor 10 by a joint 30 to the side edges of the rubber mat 20"
It was a thing.

That is, in the up Rufuroa 10 of this, as shown in FIG. 1, in which the respective rubber mats 20 to fix by using the joint 30. In flop Rufuroa 10 of this, as the joint 30 may be one such as shown in the best mode described below, "L-type", but in the cross-sectional "U-shaped", a top plate 11 and the rubber mat 20 What was simply pinched | interposed and the "screw shape" which screws on the top plate 11 through the hole provided in the rubber mat 20 may be used.

  Since the rubber mat 20 is fixed on the top plate 11 by the joints 30 as described above, the rubber mat 20 in the pool floor 10 is very coupled with stabilization by the drain holes 23. It is fixed on the top plate 11 in a stable state.

Therefore, up Rufuroa 10 This is to demonstrate the ability to have noted above, of course, is the stabilization of the rubber mat 20 is further achieved by a joint 30.

It should be noted, is attached to this preference Rufuroa 10,
“The joint 30 is composed of an upper surface 30a that holds the rubber mat 20 and a side surface 30b that hangs substantially vertically from the upper surface 30a, and is engaged with the side edge of the pool floor 10 inside the lower end of the side surface 30b. The joint part 31 was formed integrally. "
It can also be .

Chi words, the joint 30 for stopping the rubber Mumatto 20 on the top plate 11 consists of a top surface 30a for pressing the rubber mat 20, the side surface 30b extending downwardly from the upper surface 30a in a substantially vertically downward in cross section substantially "L Jo "is obtained by the so things, is because it to be set to a shape according to the preferred embodiment shown in FIGS. 1 and 5-7.

In this pool floor 10, the side to be engaged with the side edge of the pool floor 10 as clearly shown in FIGS. 6 and 7 (c) inside the lower end of the side surface 30 b of the joint 30. there it is possible to as also integrally formed engaging portion 31.

  When the rubber mat 20 is fixed on the top plate 11 using the joint 30 as described above, the upper surface 30a of the rubber mat 20 is placed on the top plate 11 as shown in FIGS. The lower end of the side surface 30b reaches the lower end of the side edge of the pool floor 10, and the engaging portion 31 formed inside the lower end of the side surface 30b engages with the lower end of the side edge of the pool floor 10 To do.

  That is, the joint 30 is simply fitted from the side of the pool floor 10 with the rubber mat 20 laid on the top plate 11 as shown in FIG. It can be fixed on the plate 11. Of course, even in the operation of removing the joint 30, it is only necessary to pull the joint 30 in the lateral direction.

  Of course, the joint 30 may be integrally formed using a synthetic resin in the same manner as the pool floor 10. Further, since the joint 30 is “L-shaped”, it can be used anywhere on the side edge of the pool floor 10 and can be stacked without being bulky.

Therefore, in the above-flop Rufuroa 10 where the joint 30 is employed, it is possible to allow easy installation and removal operations of di Yointo 30.

The engagement in this flop Rufuroa 10, for each of its joints 30, 5, 6, as shown in (b) and (c) of FIG. 7, the inside of the knob portion 32 constituting the joint 30 Rukoto to form a protrusion 33 in projected state can also.

  The rubber mat 20 on the pool floor 10 may be removed while it is still in the pool. At this time, since the rubber mat 20 is attached by the joints 30, the joints 30 have to be removed by putting their hands in the water. However, the joints 30 are not visible as long as they are not submerged in the water. At this time, the knob part 32 provided in each joint 30 is useful.

  The knob portion 32 is used when the engaging portion 31 is pushed down slightly when the engaging portion 31 of each joint 30 is attached to or removed from the lower end of the side edge of the pool floor 10. It can be easily attached and removed. In other words, since the engaging portion 31 is located in a portion that cannot be seen from the outside under the top plate 11, if the presence of the knob portion 32 is confirmed with a finger and then pressed down, the joint 30 can be easily attached and detached. It will be possible.

Therefore, up Rufuroa 10 This may be not exhibit the same effect as the above SL is the attachment and detachment operation of the joint 30 is made to those performed in more easily.

Element, is attached to this preference Rufuroa 10,
"Joint 30, form forming a relief aperture 36 for releasing this portion corresponding to the side edges of the pool floor 10 '
You can also

That is, has the joint 30 which was used in the up Rufuroa 10 of this, as shown in (a) to (c) of FIG. 8 is obtained by forming an opening 36 escape to the portion of the upper surface 30a, the relief by also in the range it is possible to avoid exposure the side of the pool floor 10 in the opening 36.

  That is, the joint 30 is used by being fitted to the side edge of the pool floor 10, but the part made by long-term use on the side edge side of the pool floor 10 to be fitted. If there is a general protrusion or the joint 30 itself is fitted in a slightly inclined state, “joint” may occur in the joint 30 after the attachment is completed. However, in the joint 30 according to the sixth aspect, since the projection on the pool floor 10 side enters the escape opening 36, such “backlash” is absorbed by the escape opening 36.

  The relief opening 36 also smoothes the water flow around the joint 30. For this reason, when a water flow is generated in the pool, the water flow freely enters and leaves the escape openings 36 of the joints 30 and the joint 30 does not come off due to the water flow.

Therefore, the pool floor 10 and the aperture 36 formed in the joint 30 relief, other can exhibit the same effect as above SL, than it is possible to prevent the rattling of the joint 30 fitted with a rubber mat 20 on the pool floor 10 .

As detailed above, in the present invention,
“A pool floor 10 that is submerged in the pool and used to reduce the depth of this pool,
The rubber mat 20 was laid on the top plate 11 of the pool floor 10 and the side edges of the rubber mat 20 were fixed to the side edges of the pool floor 10 by the joints 30. "
The main feature of the construction is that the depth of the water in the pool can be adjusted, and the rubber mat 20 on the top can provide an anti-slip effect during use of the pool floor 10. The pool floor 10 can be provided.

Then, this onset bright configured as described above, that explains the pool floor 10 which is the best mode illustrated in the drawings.

  FIG. 1 shows a perspective view of a pool floor 10 provided with a rubber mat 20 according to the present invention. This pool floor 10 is submerged in a pool (not shown) to reduce the depth of the pool. Although used, a rubber mat 20 is laid on the top plate 11 of the pool floor 10.

  The pool floor 10 is made of synthetic resin such as vinyl chloride and is formed so as to have a specific gravity of about 1.55 so as to sink into water, as shown in FIGS. 1, 11, and 12. As described above, the top plate 11 and a plurality of legs 12 that support the top plate 11 are provided.

  As shown in FIG. 10, the top plate 11 of the best mode is formed by connecting a plurality of downwardly “U-shaped” plates, and there is a gap of about 1 mm deep between each plate. Is formed. The drain hole 23 of the rubber mat 20 faces the gap.

  Each leg 12 has a foldable box shape, and can be folded under the top plate 11 when the pool floor 10 is not used. Further, as shown in FIGS. 1 and 11, a dive prevention plate 13 is attached to each developed leg 12 so that a child cannot dive between each leg 12 to prevent a child accident. It is.

  The rubber mat 20 fixed on the top plate 11 of the pool floor 10 has to be submerged in water so that the specific gravity is about 1.3 and the weight of one piece is about 7 kg. 1 to 5, a base 21 to be placed on the top plate 11, a large and small protrusion 22 formed on the surface of the base 21, and a space between these protrusions 22. It has a drain hole 23 formed in the base 21 located. Although a protrusion may be formed on the back surface of the base portion 21 of the rubber mat 20, in the best mode, the back surface of the base portion 21 is a flat surface.

  Each of the protrusions 22 is used for massaging the sole and preventing slipping on a person walking on the rubber mat 20 as in the case of Patent Document 1, and the planar shape thereof is as shown in FIGS. In addition, in the case of a circular shape, an elliptical or polygonal shape can be applied. Of course, the upper end of each protrusion 22 should be round so that it does not hurt when touched by a foot.

  The drain holes 23 formed between the protrusions 22 allow the water in the pool to enter and exit from the base 21. For example, the rubber mat 20 is later placed on the pool floor 10 submerged in the pool. 11 is used to drain water when placed on the top 11, and the rubber mat 20 can be placed on the top board 11 quickly. Further, each water drain hole 23 also serves to allow the tributary to escape well when a water flow is generated with respect to the rubber mat 20 placed on the top plate 11. It is also something to prevent.

  The drain hole 23 may be implemented as an ellipse or a polygon as well as a perfect circle as exemplified in the best mode, but its size does not feel when the sole touches it. In order to do so, for example, it may be equal to or smaller than each of the protrusions 22 described above. Further, the shape of the inner surface forming each drain hole 23 may be vertical or may have a wide “C” shape at the bottom. This is because the flow of water to the drain hole 23 is made good and pain is not felt by the drain hole 23.

  Further, when the rubber mat 20 is placed on the top plate 11, the drain hole 23 is preferably opposed to the gap formed on the top plate 11 side as shown in FIG. 10. This is because the water flow generated in the pool passes through or enters through each drain hole 23, and the rubber mat 20 is sufficiently stabilized on the top plate 11. In the rubber mat 20 of the best mode, a large number of drain holes 23 are formed, and the top plate 11 has many rows of gaps. Therefore, as shown in FIG. 23 opposes the gap on the top plate 11 side.

  In the rubber mat 20 of the best mode, the relationship between the protrusions 22 and the drain holes 23 is that when the plurality of rubber mats 20 are slightly shifted and overlapped, the other rubber mat is placed in the drain hole 23 of one rubber mat 20. Twenty protrusions 22 are inserted. Thereby, positioning when stacking the plurality of rubber mats 20 and low stack (stacking so as not to generate useless space) can be performed.

  Moreover, in the rubber mat 20 of the best mode, as shown in FIG. 2, a plurality of joint engaging recesses 24 are formed on the side portion thereof. The joint engaging recess 24 is a portion into which an upper surface 30a of the joint 30 to be described later is inserted, and serves to clearly indicate the fixing location of the joint 30 and stabilize the fixing of the joint 30. Further, as shown in FIGS. 2 and 5, a fitting hole 25 into which an engagement protrusion 33 of the joint 30 described later is fitted is formed in the innermost part of the joint engagement recess 24. However, the fitting hole 25 is a long hole so that two distant engaging projections 33 can be fitted simultaneously to position the joint 30.

  A back notch 26 into which the connector 40 is fitted is formed on the lower surface of the edge of each rubber mat 20 to be abutted against each other, and this back notch 26 is used as shown in FIG. Thus, a plurality of rubber mats 20 can be connected. As shown in FIG. 9, the connector 40 is formed by integrally forming two engagement protrusions 41 on a substrate, and this substrate is fitted into each of the back notch portions 26. The engagement protrusions 41 are fitted into the drainage holes 23 using the drainage holes 23 in the vicinity of the back notch 26 as engagement holes.

  When the rubber mat 20 is placed on the pool floor 10, the rubber mat 20 is substantially in close contact with the top plate 11 because the lower surface is flat. For this reason, when a strong water flow is not generated in the pool, the rubber mat 20 rides on the pool floor 10 in a stable state. When a strong water flow is generated in the pool, the rubber mat 20 may float from the pool floor 10. However, since the drain hole 23 is formed in the rubber mat 20, the strong water flow comes out from the drain hole 23. As a result, the effects of water flow are immediately eliminated. That is, even if the rubber mat 20 floats from the pool floor 10, it is partial, and the water flow from each drain hole 23 causes the lift from the pool floor 10 to be about several millimeters and immediately. It will disappear.

  The above rubber mat 20 is fixed on the top plate 11 of the pool floor 10 by each joint 30 as shown in FIG. As shown in FIGS. 5 to 8, the joint 30 is inserted into the joint engaging recess 24 on the rubber mat 20 side and presses the rubber mat 20 onto the top plate 11, and the upper surface 30 a A side surface 30b extends downward through the chamfer 35 and forms an “L-shape” together with the upper surface 30a.

  On the upper surface 30 a of the joint 30, as shown in FIGS. 7 and 8 (B) and (B), two engaging protrusions 33 formed on the tip side and one drainage in the central portion. A mouth 34 is formed. As described above, the two engaging projections 33 are simultaneously fitted in the fitting holes 25 on the rubber mat 20 side to fix and position the upper surface 30a. When re-fixing 30, water can enter and exit, and the joint 30 does not stick to the rubber mat 20.

  On the other hand, the engaging portion 31 is integrally formed on the side surface 30b of each joint 30 as shown in FIGS. As shown in FIG. 5, the engaging portion 31 is to be engaged with the side edge of the pool floor 10, and ensures that the joint 30 is fixed to the rubber mat 20 or the pool floor 10. Is. That is, the engaging portion 31 is inserted into the joint engaging concave portion 24 of the rubber mat 20 from the lateral direction, and at the end of the insertion, as shown in FIG. It is engaged with the lower end of the edge, and the joint 30 is fixed by the cooperation of the engaging portion 31 and the upper surface 30a.

  Further, in the joint 30 of the best mode, as shown in FIG. 6, the knob portion 32 is integrally formed inside the engaging portion 31 formed on the side surface 30b. The knob portion 32 is used to pinch or hang a finger on the knob portion 32, thereby enabling the joint 30 to be easily removed.

  FIG. 8 shows the second embodiment of the joint 30 described above. In this joint 30, the point that the relief opening 36 is formed in the portion straddling the upper surface 30 a and the chamfer 35 is shown in FIG. 7. This is different from the joint 30. Since the other parts are the same as those of the joint 30 in FIG. 7, the same reference numerals are given in FIG. 8, and the description of the constituent parts other than the relief opening 36 is omitted.

  The relief opening 36 of the joint 30 shown in FIG. 8 is configured so that the side surface of the pool floor 10 does not hit as shown in FIGS. 8 (A) to 8 (C). Even if a partial protrusion or the like is made on the side edge side of the floor 10, the protrusion or the like on the pool floor 10 side escapes and enters the opening 36, thereby absorbing “backlash” due to this.

  Note that the rubber mat 20 of the best mode is of a size that can be used for two pool floors 10 and, as shown in FIG. Connected. The connector 40 is configured such that its base portion is inserted into a back notch portion 26 formed on the rubber mat 20 side, and is inserted into a drain hole 23 near the joint engagement recess 24 on the center upper surface of the base portion. It has two engaging projections 41 to be fitted.
