Description

  The present invention relates to a pool lifting floor apparatus that includes a pool lifting floor that can be moved up and down in a pool and that can change the water depth of the pool, and that includes a slope that can be easily lowered to the pool lifting floor.

  Many pools have been proposed in which the pool floor can be raised and lowered to change the depth of the pool, and in order to allow elderly people, children, or disabled people to walk into the pool, There is also known one provided with a slope leading to the pool lifting floor (see Patent Document 1).

JP 2002-4613 A

The device shown in Patent Document 1 has a structure in which a slope is pivotably attached to an entrance of a pool so that the slope can be tilted, and a roller provided at a lower end of the slope is engaged with a pool raising / lowering floor. It is a structure that is pivotally supported at the entrance end of the pool so that it can rotate horizontally, and since this shaft part is not a structure that can be moved up and down, the highest position of the pool lifting floor moves the slope to the horizontal state. Even so, there is a problem that the position below the tread portion of the slope is the limit, and the pool lifting floor cannot be structurally raised to a position flush with the peripheral edge of the pool.

  The present invention was devised in view of the current situation, and the object of the present invention is to set the pool lifting floor at a level position flush with the peripheral edge of the pool when the pool is not used. An object of the present invention is to provide a pool elevating floor device that can be secured and can effectively use a pool opening.

  In order to achieve the above object, according to the first aspect of the present invention, there is provided a pool elevating floor apparatus, a pool elevating floor disposed in a manner capable of elevating and lowering in the pool, elevating means for the pool elevating floor, A slope that is movable from the entrance to the pool elevating floor, the entrance side end of the slope being pivotally supported with respect to the upper edge of the pool, and the entrance The side end portion is slidably held with respect to a bearing disposed on the upper edge of the pool, and the pool elevating floor is formed to be movable up and down to the upper edge of the pool.

  In the invention according to claim 1, the pool lifting floor device is configured such that the pool lifting floor is disposed so as to be liftable in the pool, the lifting means for the pool lifting floor, and the pool entrance to the pool lifting floor. A slope that is movable, the inlet end of the slope being pivotally supported relative to the upper edge of the pool, and the inlet end of the slope Since the pool elevating floor is slidably held with respect to the bearing disposed on the upper edge, and the pool elevating floor is formed to be able to elevate to the upper edge of the pool. It is safe because it can be easily set at the same height position and the step can be eliminated, and the pool lifting floor can be effectively used by closing the pool opening.

  Hereinafter, the present invention will be described in detail based on embodiments of the invention shown in the accompanying drawings.

FIG. 1 is a plan view showing a configuration of a pool elevator floor apparatus according to an embodiment of the present invention, and FIG. 2 is an explanatory diagram showing a state where the pool elevator floor of the pool elevator floor apparatus is raised to the highest position. 3 is an explanatory view showing a state where the pool lifting floor of the pool lifting floor apparatus is set at a shallow water depth, and FIG. 4 shows a state where the pool lifting floor of the pool lifting floor apparatus is set at a deep water depth position. FIG. 5 is an enlarged explanatory view showing the slope holding portion in the state of FIG. 2, FIG. 6 is an enlarged explanatory view showing the slope holding portion in the state of FIG. 4, and FIG. The enlarged explanatory views viewed from the direction are shown respectively.

The elevator floor apparatus according to the present embodiment includes an elevator floor 2 that is movable along the vertical direction of the opening of the pool 1 and in which air is enclosed so that the buoyancy in water is substantially zero, and the elevator floor 2. Each of them is composed of an elevating device that moves up and down independently along the vertical direction, and a slope 20 for descending to the elevating floor 2.

In this embodiment, the elevating floor 2 is not particularly shown, but is made of a large number of rectangular tube materials made of aluminum, stainless steel, or synthetic resin, and is placed under these floor materials to fix the floor materials. And a support frame assembled into a supporting rectangle.

A large number of flooring materials are arranged in parallel to each other. For example, in the case of a pool having a width of 5 m and a length of 15 m, a large number of flooring materials are assembled into a rectangular shape and fixed to the upper surface of the support frame by bolt nuts or the like. The

The hollow interior of each square cylinder floor is filled with air and can be sealed with rubber cap plugs fitted at both ends thereof. By configuring in this way, the lifting floor 2 can be given buoyancy in water to reduce its weight. In particular, only a part of the flooring is filled with air and sealed with a plug, The underwater weight of the lift floor 2 can be adjusted as appropriate by removing the plug of the floor material. In this case, if the total gravity and buoyancy of the lift floor 2 are balanced, the weight of the water becomes zero, and the driving force required to raise and lower the lift floor 2 in water can be minimized. Of course, the buoyancy may be adjusted by attaching a float to the lower surface of the lift floor 2 so as to be detachable.

On the other hand, the support frame includes the plurality of floor materials and a plurality of connecting members that connect the floor materials arranged adjacent to each other in the horizontal direction. As a constituent material of this flooring, an inherently lightweight material such as an aluminum material, a synthetic resin material, or a stainless material, or a lightened material is used. The flooring thus formed is connected to have a desired area by various known connecting members.

The size of the elevating floor 2 configured as described above is formed to have a plane area substantially the same as the opening area of the pool 1 to be attached.

As an elevating device that moves the elevating floor 2 configured as described above up and down, for example, an elevating device disclosed in Japanese Patent Laid-Open No. 2000-282699 can be used.

This lifting device is arranged in the vertical direction facing the opposite side wall of the pool 1 and is slidably fitted into notches formed at both longitudinal ends of the lifting floor 2 to lift and lower the lifting floor 2. A plurality of hollow guide rails for guiding, a group of pulleys respectively provided on the guide rail, the support frame and the pool side, an electric motor as a drive source provided on the pool side, and the electric motor being interlocked with the electric motor It is composed of a continuously variable transmission as a reduction transmission, and a plurality of strips such as chains, ropes, wires, etc., one end of which is connected to a winding pulley and the other end is connected to a lifting floor 2.

As shown in the official gazette, the pulley group includes an upper and lower pulley, a drive pulley, a guide pulley, and a tension pulley that applies an appropriate tension to a rope suspended on these pulleys.

This tension pulley has been described as an example where it is disposed between the drive pulley and the upper pulley, but the position of the tension pulley is not limited to this, and an appropriate tension is applied to the rope. Any position can be used as long as it can be applied. Also, the tension applying method can be adjusted by, for example, moving a tension pulley forward and backward with a bolt, a cylinder, or the like, or by applying a spring biasing force.

Therefore, by rotating the electric motor forward / reversely, the winding pulley is decelerated and rotated at an appropriate speed via the continuously variable transmission to wind or rewind each wire. The elevating floor 2 can be raised and lowered along the guide rail to change and adjust the water depth of the pool 1. Of course, when the elevating floor 2 reaches the upper limit position or the lower limit position, a switch (not shown) set at each position is operated to automatically stop the electric motor rotation.

If the amount of air filled in the flooring material is appropriately adjusted so that the weight of the lift floor 2 is equal to the buoyancy in water, the lift floor 2 can be smoothly raised and lowered with a small driving force. It is economical because the torque of the electric motor necessary for raising and lowering the elevating floor 2 can be minimized and a small electric motor can be used.

Of course, in this invention, the raising / lowering device of the pool raising / lowering floor 2 is not limited to the said example of description, For example, the thing using a fluid pressure cylinder, the motor and the gear were used. Various known lifting devices such as those using a pantograph mechanism can be used.

The slope 20 is pivotally supported by a shaft 22 so that the upper end of the slope 20 can be tilted around a horizontal axis at the inlet 1a of the pool 1 protruding from the corner of the peripheral edge of the pool 1, and the other end of the slope 20 is Although not shown in particular, the roller is pivotally supported and engaged with the landing part of the lifting floor 2, and when the lifting floor 2 moves up and down, the roller 20 is mounted so that the slope 20 rises while rolling on the landing part. It has been.

A handrail 21 protrudes upward from the inner edge of the slope 20. Of course, the floor surface of the slope 20 is formed with unevenness for slip prevention.

Further, as shown in FIGS. 5 to 7, the shaft 22 that supports the slope 20 is pivotally attached to a bearing 23 that holds the shaft 22 so as to be movable up and down. 1 is inserted into and held by a cylindrical holder 4 fixed to the pool wall surface 3 of the inlet 1a.

Therefore, the slope 20 follows the up-and-down movement of the up-and-down floor 2 and tilts while changing its inclination angle as shown in FIGS. At this time, the bearing 23 that supports the shaft 22 is held so as to sink into the holder 4 as shown in FIG.

From this state, when the elevating floor 2 is further raised to the highest position where the upper surface of the elevating floor 2 is flush with the peripheral edge of the pool 1, the slope 20 is pushed up by the elevating floor 2 and the peripheral edge of the pool 1. It rises to a position higher than the part. At this time, since the bearing 23 that supports the shaft 22 is merely slidably inserted into the holder 4, it rises following the ascending movement of the slope 20, so that the upper surface of the elevating floor 2 is It can be reliably raised to the highest rise position that is flush with the peripheral edge of the pool 1.

In the above embodiment, the present invention has been described by taking the slope provided on the raising / lowering floor of the pool as an example. However, the present invention is not limited to this, for example, a slope used for entering and exiting a bathtub. Can also be applied.

It is a top view which shows the structure of the pool raising / lowering floor apparatus based on the Example of this invention. It is explanatory drawing which shows the state which the pool raising / lowering floor of the pool raising / lowering floor apparatus rose to the highest rise position. It is explanatory drawing which shows the state by which the pool raising / lowering floor of the pool raising / lowering floor apparatus was set in the shallow position of water depth. It is explanatory drawing which shows the state by which the pool raising / lowering floor of the pool raising / lowering floor apparatus was set to the deep water depth position. FIG. 3 is an enlarged explanatory view showing a slope holding part in the state of FIG. 2. FIG. 5 is an enlarged explanatory view showing a slope holding part in the state of FIG. 4. It is the expansion explanatory view which looked at the slope holding part from other directions.
