Description

  The present invention relates to a pool floor provided with a plurality of legs attached to a floor board and provided with a dive prevention board, and relates to a pool floor for sinking this into the pool and forming a shallow portion in the pool by the floor board. is there.

  Various types of pool floors have been proposed, and the pool floor already proposed by the applicant is a floor plate with a plurality of legs attached, and the height of each leg is adjusted. This has the effect that the auxiliary leg portion for performing the above can be selectively fitted and the depth of the pool can be varied.

However, when this type of pool floor is not used, it is thought that these will be stacked somewhere, but each leg is fixed and protrudes, thus taking up space. For this reason, as proposed in Patent Document 1 or Patent Document 2, the leg itself can be freely folded.
Japanese Patent Application Laid-Open No. 11-101013, abstract, paragraph 0009, FIG. JP 2000-199353 A, Abstract

  The invention described in Patent Document 1 was made for the purpose of “configured so that the pool floor installed at the bottom of the pool can be folded small when not in use to reduce the depth of the pool”. As shown in FIG. 10, “the leg body 4 supporting the floor board 1 is connected to the plurality of leg members 7 and 8 through the connecting member 9 so as to be freely opened and closed, and the one leg member 7 is connected to the leg base 6. The shaft is fixed, the engagement receiver 11 is attached to the leg base 6, and the other leg member 8 can be detachably locked to the engagement receiver 11. " The leg 4 can be assembled by bending the V-shape and engaging the leg member 8 with the engagement receiver 11, while the engagement with the engagement receiver 11 is released and the leg members 7, 8 are disengaged. , So that the legs 4 can be folded in a small and flat manner if they are folded so as to overlap each other and stored in the leg material storage portion 14 of the footrest 6. It is believed to be.

  That is, as can be understood from FIG. 10, the leg body 4 of this Patent Document 1 is “if the leg members 7 and 8 are bent in a V shape and the leg member 8 is engaged with the engagement receiver 11. Although it can be assembled ", it is considered that the operation must be performed by a person with both hands for each leg 4. In that case, it is considered that the assembly and folding of each leg 4 of this pool floor takes considerable effort and time. In other words, each leg 4 of the pool floor described in Patent Document 1 can be folded and flattened, which is convenient, but it is considered that this involves considerable troublesome work.

  Further, when a large floor board is supported by a plurality of “legs 4” or “legs” in Patent Document 1, the space between the “legs 4” or “legs” is inevitably opened. From this gap, for example, children may inadvertently enter the lower side of the floor board, or from this gap, it may be possible to enter under the floor board in an interesting half. Therefore, in the “pool floor” of Patent Document 1, as described in paragraph 0009, “a side plate support portion is provided on one side of at least one leg member, and one side of the assembled leg is crossed. The measures are taken such that “the side plate is arranged to be disposed”, and thereby, “the risk of the child entering the leg body can be prevented by passing the side plate to one side of the leg body”. It has become a thing.

  In this case, in Patent Document 1, as shown in FIG. 10, “it is preferable to provide a recess 16 for storing the side plate support portion (plate 13) in the peripheral side wall portion of the leg base storage portion”. However, the "concave portion 16" cannot be put with "the side plate is passed to one side of the leg". For this reason, in the “pool floor” of Patent Document 1, the work of “passing the side plate to one side of the leg” and the work of folding and storing each leg are further complicated and troublesome. In addition, it is considered that it cannot be stored with the “side plate on one side of the leg”.

  Therefore, Patent Document 2 states that “a pool floor formed such that a plurality of legs are attached to a floor board and the floor board is supported by the leg body is folded in a small size with a board material for preventing dive when not in use. 11, for the purpose of being able to be stacked and stored horizontally, as shown in FIG. 11, “the frame plate 6 fixed to the floor plate is provided so as to be able to be engaged with each other, and the original end portions thereof are appropriately arranged. The leg 3 is composed of a pair of leg plates 7 and 8 that are pivotally attached to the frame plate with a space therebetween, so that at least one of the pair of leg plates 7 and 8 is within the thickness range of the leg plate. The dive prevention plate receiving portion 9 provided on the base plate is formed, and both ends of the dive prevention plate 10 are inserted and attached to both dive prevention portion plate receiving portions 9 of the adjacent legs 3 and 3. "Floor" has been proposed.

  In the “pool floor” of Patent Document 2, “the dive prevention plate 10 fits within the thickness range of the leg plates 7 and 8, so that the entire pool floor can be folded and stably stacked”. However, since “the dive prevention plate receiving portion 9 provided in at least one of the pair of leg plates 7 and 8 so as to be within the thickness range of the leg plate” is formed, This requires a complicated operation of “inserting and attaching both ends of the dive prevention plate 10 to both dive prevention portion plate receiving portions 9 of the matching legs 3 and 3”.

To summarize the above, for this type of pool floor,
(1) Each leg can be folded and unfolded as easily as possible so that it can be installed in the pool and stored and stacked smoothly when not in use. (2) Submerged in the pool and in use for the pool floor, that it does not Mogurikome is easy from between their respective legs (3) when using the "dive preventing plate" lengthy plate-shaped as being achieving this (2) (4) When folding each leg and transporting it for storage, make sure that the folded leg does not open and the leg components do not flutter. Improvements in various aspects are desired.

  That is, an object of the present invention is to provide a pool floor with a simple configuration in which each leg can be easily expanded and folded, and can be prevented from entering under the floor board when in use.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“A pool floor 100 comprising a floor board 10 and a plurality of legs 20 supporting the floor board 10 and forming a shallow portion of the water depth by the floor board 10 in the pool when submerged in the pool,
Each leg 20 is composed of at least a leg plate 21 and a drawer leg plate 23 so that the leg 20 can be unfolded and folded.
The same position of each leg plate 21 outer surface, by that form each dive preventing plate mounting portion 25 outer surface and opposite ends are opened, with each dive preventing plate mounting portion 25 is adapted to be positioned on the same plane , to respective submerged prevention plate mounting portion 25, forms the shape of the locking projections 26 facing each other,
The dive preventing plate 40, the preventing plate mounting portion 25 disposed on the same plane, the longitudinal insertion or the included widthwise bending, characterized in that as Fit the by engagement by the engaging projection 26 Pool floor 100 "
It is.

  That is, the pool floor 100 according to claim 1 comprises a floor board 10 and a plurality of legs 20 that support the floor board 10 as shown in FIGS. 1 to 4. As shown in FIG. 1 and FIG. 2A, etc., there is a gap between each leg 20. Such a gap is covered with a dive prevention plate 40 shown in the figure. This dive prevention plate 40 is attached to each leg 20 by the following means.

  Each leg 20 in the best mode to be described later is attached to a leg base 30 fixed to the back surface of the floor board 10 as shown in FIG. 7, and one end is attached to the leg board 21 and folded. The folding member 22 as shown in (a) and a drawer leg plate 23 as shown in FIG. 8 connected to the other end of the folding member 22 and attached to the leg base 30 are developed. In this case, the box shape as shown in FIGS. 1 to 3 is obtained. Of course, each of the legs 20 may be constituted by the side plate 21 and the extraction leg plate 23 so that the leg 20 can be developed as in the conventional example shown in FIG.

  Further, in each leg 20 constituting this pool floor 100, a slide engaging portion 24 as shown in FIG. 3 is engaged with a slide groove 31 as shown in (a), and as shown in (a) and (b) of FIG. 9, the drawer leg plate 23 is opened and closed while sliding with respect to the leg base 30. It is what I did.

  And in this pool floor 100, as shown to (i) of FIG.1 and FIG.9, although the dive prevention board 40 is attached, this dive prevention board 40 is each each forming the same plane of the some leg 20. As shown in FIG. It is detachably attached to the outer surface of the leg plate 21.

  That is, as shown in FIGS. 2 (a), 4 and 7 on the outer surface of each leg plate 21, a dive prevention plate mounting portion 25 having an open outer surface and both ends is formed respectively. The diving prevention plate 40 having a length over at least adjacent ones of the legs 20 forming the same plane is attached to the prevention plate attaching portion 25 as follows.

  As shown in FIG. 4, each dive prevention plate locking portion 25 is formed on the outer surface side of the side plate 21 provided with this, and for example, as shown in FIG. Both ends are open. A locking projection 26 formed integrally with the side plate 21 is protruded toward the dive prevention plate locking portion 25 and is inserted into the dive prevention plate locking portion 25 by these locking projections 26 or The fitted anti-dive plate 40 is held.

  The diving prevention plate locking portion 25 and the locking projections 26 protruding toward the above are arranged in a horizontal line and end portions when the legs 20 shown in FIG. 4 are folded. Will be open. Therefore, the long dive prevention plate 40 is inserted from the lateral end portion of the dive prevention plate locking portion 25 located at the left end or the right end in FIG. 4 is arranged at the position shown in FIG. 4, and one long side is engaged with one locking protrusion 26 in the dive prevention plate locking portion 25 as shown by a two-dot chain line in FIG. While the bent dive prevention plate 40 is bent in the width direction, the other long side is engaged with the other locking projection 26 (hereinafter referred to as “bending in the width direction”) and attached to each dive prevention plate locking portion 25. Is done.

  When the diving prevention plate 40 is bent in the width direction into the diving prevention plate locking portion 25, the two locking projections 26 projecting toward the diving prevention plate locking portion 25 are of two types, long and short. It is good to keep it. This is because if one end of the dive prevention plate 40 is inserted into the longer locking projection 26 and the other end of the dive prevention plate 40 is inserted into the shorter locking projection 26, the dive prevention is achieved. This is because the bending amount of the plate 40 can be reduced and the bending operation in the width direction can be easily performed.

  Note that the dive prevention plate 40 shown in FIG. 4 has a length substantially the same as the length of the entire pool floor 100 in the longitudinal direction, and is one piece over the entire three legs 20. However, it may be carried out so that two of the two legs 20 are used.

  Each leg 20 is folded as described above, and the pool floor 100 in which the dive prevention plate 40 is attached to these legs 20 is in a state as shown in FIG. Therefore, in order to deploy each leg 20 to use the pool floor 100 as shown in FIG. 1 and FIG. 2 (A), the dive prevention plate 40 attached to the dive prevention plate attaching portion 25 is held and pulled as it is. If it wakes up, each leg 20 which has been folded will stand in a state as shown in (b) of FIG. Of course, in order to change from the standing state as shown in FIG. 9 (b) to the folded state as shown in FIG. 9 (a), it is only necessary to push down the dive prevention plate 40, contrary to the above. Needless to say.

  After each leg 20 that has been folded is erected in the state shown in (b) of FIG. 9, if each leg 20 is unfolded by the required unfolding method, 2 and FIG. 3 will be developed as shown in FIG. Of course, when the reverse operation is performed, it is folded into the state shown in each of FIGS.

  In the pool floor 100 in which each leg 20 is deployed, since the dive prevention plate 40 is attached to the dive prevention plate locking portion 25, as shown in FIG. 1, FIG. 2, and FIG. Thus, the dive prevention plate 40 covers the gaps between the legs 20, and the dive under the floor plate 10 constituting the pool floor 100 is prevented.

Therefore, according to the pool floor 100 of this claim 1,
(1) Each leg 20 can be easily folded and unfolded, and the pool floor 100 can be installed in the pool and stored and stacked when not in use. (2) A pool that is used by being submerged in the pool. The floor 100 cannot easily dive between the legs 20 by the dive prevention plate 40. (3) The dive prevention plate locking portion 25 provided on each leg 20 and the engagement of the dive prevention plate 40 and the engagement are provided. Easy to do with stop projection 26
(4) If the end of each dive prevention plate 40 can be fixed to the floor plate 10 side where each leg 20 is folded, each leg 20 unintentionally unfolds when the pool floor 100 is transported. It is possible to prevent this from happening.

Now, in order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is the pool floor 100 according to claim 1,
“Support protrusions 27 for supporting the dive prevention plate 40 are formed inside each dive prevention plate mounting portion 25.
It is.

  That is, as shown in FIG. 6, the pool floor 100 according to claim 2 is formed by forming a support protrusion 27 for supporting the dive prevention plate 40 inside each dive prevention plate mounting portion 25. The protrusion 27 receives the inner surface (back surface) of the dive prevention plate 40 when the dive prevention plate locking portion 25 is attached, thereby ensuring the support of the dive prevention plate 40.

  That is, the dive prevention plate 40 includes not only a flat plate as shown in FIG. 5B but also a rigid securing ridge 42 as shown in FIG. The rigidity securing ridge 42 secures rigidity that is insufficient when the dive prevention plate 40 is formed as a thin one, and the support protrusion 27 has a shape that can support the rigidity securing ridge 42. There is. Of course, the support protrusion 27 is supported from the back surface of the anti-dive plate 40 shown in FIG. 5B, which has a sufficient rigidity by designing the material and thickness. Needless to say.

  Therefore, the pool floor 100 according to the second aspect of the present invention exhibits the same function as that of the first aspect described above, and can reliably support the dive prevention plate 40.

Furthermore, in order to solve the said subject, the means which the invention which concerns on Claim 3 took about the pool floor 100 of the said Claim 1 or Claim 2,
“A base 30 for attaching and storing the legs 20 is attached to the bottom surface of the floor board 10, and a part of the base 30 that faces the anti-hidden plate mounting portion 25 when the legs 20 are folded is provided on the base plate 30. forming a relief recess 32, to the formation of the Kakarigo突force 33 which projects towards this diving prevention plate escape recess 32 in the isosceles 30 "
It is.

  That is, in the pool floor 100 of this third aspect, the leg base 30 is used to attach the legs 20 to the lower surface of the floor board 10, but the dive prevention board 40 extends beyond the leg base 30. In addition, fluttering during transportation of the folded leg plate 21 and the drawn leg plate 23 is taken into consideration. Therefore, in the pool floor 100 according to the third aspect of the present invention, a dive prevention plate relief recess 32 as shown in FIG. An engaging protrusion 33 protruding toward the point 32 is provided.

  That is, the dive prevention plate escape recess 32 of the leg base 30 bends the long dive prevention plate 40 attached to the folded leg 20 so as to face the dive prevention plate attachment portion 25 on the leg 20 side. At the same time, the engagement protrusion 33 formed to project toward the dive prevention plate escape recess 32 is used to engage the dive prevention plate 40 with the leg base 30 side.

  It is preferable that the positions of the leg base 30, the dive prevention plate escape recess 32, and the engaging projection 33 are as shown by the reference numerals enclosed in parentheses in FIG. That is, the dive prevention plate escape recess 32 on the leg base 30 side and the dive prevention plate mounting portion 25 on the leg plate 21 side are at the same position, but the engagement protrusion 33 is made shorter than the locking protrusion 26. .

  This is because the pool floor 100 sometimes folds each leg 20 with the dive prevention plate 40 attached and transports the leg 20 in an upright state. This is because when the prevention plate escape recess 32 and the engagement protrusion 33 are engaged, the leg plate 21 and the drawer leg plate 23 are prevented from fluttering. At this time, the dive prevention plate 40 is moved to somewhere due to gravity, and either end thereof is one end of the dive prevention plate mounting portion 25 on the leg 20 side in FIG. It will be located in a part and will engage with the leg stand 30 side.

  On the other hand, in the pool floor 100 according to the third aspect, since each leg 20 is developed by causing the dive prevention plate 40, the dive prevention plate 40 is engaged with the leg base 30 at this time. It cannot be expanded. Therefore, the engagement with respect to the leg plate 21 is maintained while disengaging from the leg base 30 side by slightly shifting the diving prevention plate 40 (at the position shown in FIG. 6).

Therefore, the pool floor 100 according to claim 3 exhibits the same function as that of claim 1 or claim 2 described above,
(4) When the legs 20 are folded and transported for storage, fluttering of the leg plates 21 and the drawer leg plates 23 constituting the folded legs 20 is prevented.

As described above in detail, in the present invention,
“A pool floor 100 comprising a floor board 10 and a plurality of legs 20 supporting the floor board 10 and forming a shallow portion of the water depth by the floor board 10 in the pool when submerged in the pool,

The same position of each leg plate 21 outer surface, by that form each dive preventing plate mounting portion 25 outer surface and opposite ends are opened, with each dive preventing plate mounting portion 25 is adapted to be positioned on the same plane , to respective submerged prevention plate mounting portion 25, forms the shape of the locking projections 26 facing each other,
The dive preventing plate 40, the flush-shield plate mounting portion arranged on the 25, the longitudinal insertion or the included widthwise bending, it has to Fit the by engagement by the engaging projection 26 "
The pool floor 100 can be provided with a simple configuration by which each leg 20 can be easily expanded and folded, and can be prevented from sinking under the floor board 10 when used. It can be done.

  Next, each of the inventions configured as described above will be described with respect to the pool floor 100 which is the best mode shown in the drawings. FIG. 1 is an overall perspective view of the pool floor 100 according to the present invention. In the pool floor 100, a single floor board 10 is supported by a total of six legs 20, as shown in FIGS. Each of the floor plate 10 and the legs 20 is formed of a plastic material, and the pool floor 100 as a whole has a weight that can be submerged in the pool.

  The floor plate 10 itself may be a single plate, but in the best mode, the floor plate 10 is formed by combining a plurality of synthetic resin panels, and a pool in which the pool floor 100 is submerged on the upper surface. The water depth inside is reduced.

  That is, the pool floor 100 according to the present invention has a basic configuration in which a total of six legs 20 are provided on the lower surface of the flat floor board 10 as shown in FIGS. Reference numeral 20 denotes a leg plate 21 as shown in FIG. 7 attached to the rear surface of the floor plate 10 or a leg base 30 fixed thereto, and one end attached to the leg plate 21 and folded as shown in FIG. The folding member 22 is connected to the other end of the folding member 22 and attached to the floor plate 10 or the leg base 30 side as shown in FIG.

  The six legs 20 constituting the pool floor 100 according to the present invention are respectively attached to the rear surface of the floor board 10 or each leg base 30 fixed to the floor board 10. The slide groove 31 as shown in FIG. 3 is formed, and the slide engaging portion 24 that engages with the slide groove 31 is formed in the drawer leg plate 23 as shown in FIG. The drawer leg plate 23 is made slidable with respect to the footrest 30, that is, the back surface of the floor plate 10.

  When the leg 20 is directly attached to the back surface of the floor plate 10, the slide groove 31 is formed directly on the back surface of the floor plate 10, or a guide rail is attached to the back surface of the floor plate 10 and is formed by this guide rail. The groove is a slide groove 31. When the leg base 30 is fixed to the back surface of the floor board 10 and the drawer leg board 23 of each leg 20 is slidably connected thereto, the slide groove 31 is formed in the leg base 30 as described above. Just keep it.

  Each leg 20 of the best mode is assembled to a leg base 30 attached to the back surface of the floor board 10, and a leg board 21 to be attached to the back surface of the floor board 10 or the leg base 30 fixed thereto. A folding member 22 that is attached to one end of the leg plate 21 and folded, and a drawer leg plate that is connected to the other end of the folding member 22 and is attached to the back surface of the floor plate 10 or the side of the leg base 30 fixed thereto. As described above, it is constituted by 23.

  Each of these legs 20 is unfolded as shown in FIGS. 2 and 3 (A), and as shown in FIGS. 2 and 3 (B). Each of the pool floors 100 is folded so that the overall size of the pool floor 100 can be reduced. Each leg 20 may be directly attached to the back surface of the floor board 10 so that the leg base 30 is omitted.

  As shown in FIG. 7, the leg plate 21, which is a first member for constituting each leg 20, is provided on the back surface of the floor plate 10 or between the two shaft supports of the above-described leg base 30 fixed to the floor plate 10. A substrate portion that is pivotally attached, a side plate portion that is formed integrally with the substrate portion and forms one surface of the “box”, and is integrated with a lower end of the side plate portion shown in the drawing and abuts on the floor surface of the pool. It mainly has a floor contact portion to be different. The leg plate 21 is pivotally attached to each pivotal attachment hole of the floor plate 10 side or both shaft supports, for example, by connecting circular protrusions formed at both ends of the base plate portion.

  Since the foldable material 22 as shown in FIG. 3A is attached to the leg plate 21, there are connecting portions for the foldable material 22 on both sides of the side plate portion. It is formed. In addition, the leg 20 of this best form has a shape maintenance material.

  With respect to the leg plate 21 configured as described above, the drawer leg plate 23 as shown in FIG. 8 is opposed to the leg plate 21 with the folding member 22 interposed therebetween. And are substantially symmetrical. That is, as shown in FIG. 8, the drawer leg plate 23 forms a substrate portion that is mounted between the two mounting bases on the leg base 30 side, and another surface of the “box” that is integral with the base plate portion. This is mainly composed of a side plate portion to be formed and a floor contact portion formed integrally with the lower end of the side plate portion in the figure.

  As shown in FIG. 8, the drawer leg plate 23 of the best mode is formed with a pulling hand 23a at substantially the center of the substrate portion, and the pulling hand 23a is pulled or pushed by placing a hand. Thus, the extension or folding of the drawer leg plate 23 with respect to the side plate 21 can be easily performed. Further, as shown in FIG. 8, the drawer leg plate 23 is formed with insertion openings 28 at portions located on both lower sides of the pull handle 23a. As shown in (b), a shorter dive prevention plate 40 can be attached.

  What is important is that each side plate 21 as described above is provided with a dive prevention plate locking portion 25 as shown in FIG. 7, and the side plate 21 faces the dive prevention plate locking portion 25. That is, the two locking projections 26 integrally formed on the side are protruded in a state of facing each other. These dive prevention plate locking portions 25 and the locking projections 26 have shapes as shown in FIG. 5 or FIG. 6 and house various types of dive prevention plates 40 to be described later. . As described above, the two locking protrusions 26 that protrude from the side plate 21 while facing each other may be of two types, long and short.

  The dive prevention plate locking portion 25 and the locking projection 26 shown in FIG. 5 are suitable for supporting a “flat plate” dive prevention plate 40 as shown in FIG. The dive prevention plate locking portion 25 itself is formed narrow. Of course, as shown in FIG. 7, each of the locking projections 26 may be formed so as to protrude plurally on one side with respect to one side plate 21 for the convenience of synthetic resin molding. However, the diving prevention plate locking portion 25 may be formed as an object having a length over the entire length direction.

Or dive preventing plate engagement portion 25 as the engaging projections 26 and projecting toward the hand, in the folded state the leg 20 shown in FIG. 4, aligned in a horizontal row, or One each dive The end of the prevention plate locking portion 25 is in an open state. Therefore, the long dive prevention plate 40 is inserted from the lateral end portion of the dive prevention plate locking portion 25 located at the left end or the right end in FIG. 4 (longitudinal insertion), or each dive prevention plate 40 is shown in FIG. As shown by a two-dot chain line in FIG. 5B, one long side is engaged with one locking projection 26 in the dive prevention plate locking portion 25. While bending the dive prevention plate 40 in the width direction, the other long side is engaged with the other locking projection 26 (bending in the width direction), and attachment to each dive prevention plate locking portion 25 is performed. .

  In the dive prevention plate locking portion 25 shown in FIG. 6, a support protrusion 27 that protrudes or bulges outward from the dive prevention plate locking portion 25 is formed. The support protrusion 27 receives the back surface of the dive prevention plate 40 housed in the dive prevention plate locking portion 25, and eliminates the gap between the attachment of the dive prevention plate 40 or the elasticity of the dive prevention plate 40. By pushing and bending it against the force, the diving prevention plate 40 is caused to generate a resilient force, and the diving prevention plate 40 is securely attached to the diving prevention plate locking portion 25. .

  Further, each leg 20 constituting the pool floor 100 of the best mode is provided with a fixing plate 29 for maintaining the deployed side plate 21 and the drawn leg plate 23 in the deployed state. As shown in FIG. 3A, the fixing plate 29 is provided inside the lower end of the side plate 21 or the drawing leg plate 23 so as to be swingable by a pivot pin. When the leg 20 is folded, the side plate 21 is fixed. Or it is folded inside the drawer leg plate 23. Further, the free end of the fixed plate 29 is engaged with a lock projection 29a formed integrally on the drawer leg plate 23 or the side plate 21, and the lock projection 29a in this best mode is shown in FIGS. 3 are formed as shown in (a) of FIG.

  When the legs 20 are unfolded, the fixing plate 29 swings its free end into the state shown in FIG. The drawer leg plate 23 is maintained in its unfolded state so that the leg 20 has a complete box shape.

Incidentally, in the case of forming the side frame 11 on the lower surface of the floor plate 10, folded leg 20, and when attached to preventing plate 40 dives to the respective diving prevention plate engagement portion 25, in FIG. 2 (b As shown in FIG. 4 and FIG. 4, the leg 20 and the dive prevention plate 40 are completely accommodated in the side frame 11, and there is no protrusion on the lower surface of the figure. The floor 100 can be stacked.

  In the present best mode, a flat plate as shown in FIG. 5B is adopted as the dive prevention plate 40, and the dive prevention plate locking portion 25 formed on the leg 20 has the dive prevention plate 40 as shown in FIG. Although it is a thing according to the cross-sectional shape of the prevention board 40, and it is sufficient for attaching the dive prevention board 40, it shows to the width direction edge part of the dive prevention board 40 in (b) of FIG. It is advisable to provide such an engaging portion 41. The engaging portion 41 bulges from the base of the dive prevention plate 40 to fill the space of the dive prevention plate locking portion 25, and the dive prevention plate 40 is placed in the dive prevention plate locking portion 25. It will be held firmly.

  Now, with regard to the leg base 30, various things can be considered if attention is paid to attaching the leg 20 to the lower surface of the floor board 10, but the diving prevention board 40 extends beyond the leg base 30. In consideration of the presence and the fluttering of the leg plate 21 and the drawer leg plate 23 during carrying, a dive prevention plate escape recess 32 as shown in FIG. Then, an engagement protrusion 33 is provided to protrude toward the dive prevention plate escape recess 32.

  That is, the dive prevention plate escape recess 32 of the leg base 30 bends the long dive prevention plate 40 attached to the folded leg 20 so as to face the dive prevention plate attachment portion 25 on the leg 20 side. At the same time, the engagement protrusion 33 formed to protrude toward the dive prevention plate escape recess 32 engages the dive prevention plate 40 with the leg base 30 side.

  In this case, the positions of the leg base 30, the dive prevention plate escape recess 32, and the engagement protrusion 33 are preferably set to the positions indicated by the reference numerals enclosed in parentheses in FIG. That is, the dive prevention plate escape recess 32 on the leg base 30 side and the dive prevention plate mounting portion 25 on the leg plate 21 side are at the same position, but the engagement protrusion 33 is made shorter than the locking protrusion 26. .

  This is because the pool floor 100 sometimes folds each leg 20 with the diving prevention plate 40 attached, and transports the leg 20 in an upright state. This is because, when engaged with the prevention plate escape recess 32 and the engagement protrusion 33, the leg plate 21 and the drawer leg plate 23 are prevented from fluttering. At this time, the dive prevention plate 40 is moved to somewhere due to gravity, and either end thereof is one end of the dive prevention plate mounting portion 25 on the leg 20 side in FIG. It will be located in a part and will engage with the leg stand 30 side.

  On the other hand, since this pool floor 100 expands each leg 20 by causing the dive prevention plate 40, it cannot be developed if the dive prevention plate 40 is engaged with the leg base 30 at this time. Become. Therefore, the engagement with respect to the leg plate 21 is maintained while disengaging from the leg base 30 side by slightly shifting the diving prevention plate 40 (at the position shown in FIG. 6).

  The dive prevention plate 40 may have a flat plate shape as shown in FIG. 5B, but as shown in FIG. 6B, the supporting protrusion protrudes outward in the center. 27 may be included. That is, the dive prevention plate 40 may be a flat plate as shown in FIG. 5 (b) if the required rigidity can be ensured by the thickness and rigidity of the material itself. In the case where it is desired to form a thin material with a small amount of a synthetic resin, it is only necessary to have a support protrusion 27 as shown in FIG.

  In either case, as shown in FIG. 5 and FIG. 6B, a rigidity securing ridge 42 is formed at the end in the width direction of the dive prevention plate 40, and this rigidity securing ridge is formed. If there is no gap when stored in the dive prevention plate locking portion 25 by 42, the attachment of the dive prevention plate 40 to the dive prevention plate locking portion 25 can be ensured.

  In addition, the length of the dive prevention plate 40 is required to extend over the two legs 20 in order to grasp the dive prevention plate 40 and simultaneously open and close the plurality of legs 20. It is also effective to use a product having the same length as the floor plate 10. This is because the end of each dive prevention plate 40 can be fixed to the two-dot chain line shown in FIG. 2B and the floor plate 10 side where each leg 20 is folded as shown in FIG. This is because it is possible to prevent the legs 20 from being unintentionally deployed when the pool floor 100 is transported.

  For this purpose, as shown in FIG. 4 and the like, the side frame 11 is fixed to the back surface of the floor board 10 and surrounding each leg 20, and the leg 20 side dive prevention plate is attached to the side frame 11. A dive prevention plate locking portion 12 similar to the locking portion 25, a locking projection 13 similar to the locking projection 26 on the leg 20 side, and a supporting projection 14 similar to the supporting projection 27 on the leg 20 side are formed. . Naturally, since the dive prevention plate 40 is linear as shown in FIG. 4, in order to fix the end to the side frame 11 side without bending it in the longitudinal direction, these dive prevention plates 40 are used. The prevention plate locking portion 12, the locking projection 13, and the support projection 14 need to face the dive prevention plate locking portion 25, the locking projection 26, and the support projection 27 on each leg 20 side. .

  The pool floor 100 according to the present invention can increase the performance of the manufacturer, as well as the “safety” and “convenience” of using the pool in facilities such as schools and swimming schools where the pool floor 100 is installed. It can be used to secure students.
