Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, for example, in a swimming competition, when a user (competitor) finishes the competition and exits the pool, they may sometimes directly exit from the pool side where they reach the goal without using the ladder attached to the side.

[0005] However, the user may be exhausted by the competition and unable to climb onto the pool side, or may need to borrow a hand from a person related to the competition to get out of the pool side. There has been a strong desire to develop a technology that can assist the user in getting out of the pool.

[0006] The present invention has been made in view of such circumstances, and an object thereof is to provide a lifting device that can assist a user in ascending and descending by performing a lifting operation.

Means for Solving the Problems

[0007] To achieve the above objective, the lifting device according to the present invention is a lifting device used by a user for raising and lowering, and is characterized by comprising: a lifting unit that moves up and down; a handle unit provided on the lifting unit for the user to grasp with their hand; a platform unit provided on the lifting unit that serves as a footing for the user; and a drive unit for raising and lowering the lifting unit.

[0008] According to the present invention, the device includes a lifting unit that moves up and down, a handle provided on the lifting unit for the user to grasp with their hands, a platform provided on the lifting unit to serve as a footing for the user, and a drive unit for raising and lowering the lifting unit. This allows the user to place their feet on the platform and grasp the handle with their hands while the drive unit raises the lifting unit, thus assisting the user in moving up and down through the lifting operation.

[0009] The handle portion is positioned to protrude forward, allowing the user to easily grasp it.

[0010] The handle portion includes a right-side handle portion provided on the right side of the main body and a left-side handle portion provided on the left side of the main body, so that a user on the right side can grasp the right-side handle portion, and a user on the left side can grasp the left-side handle portion.

[0011] The handle portion is provided so as to be inclined outward to the side from above downward, and the right handle portion and the left handle portion are provided in a V-shape, so that a user on the right can easily grasp the handle portion from the right, and a user on the left can easily grasp the handle portion from the left.

[0012] The scaffolding portion is provided on the lower end side of the main body so as to protrude forward, allowing users to easily place their feet on the scaffolding portion.

[0013] The forward projection length of the scaffolding section is set to be greater than the forward projection length of the handle section, so that when the user grasps the handle section, the user and the lifting section are approximately parallel.

[0014] In other words, if the forward projection length of the scaffolding section is small, the user's feet may act as a fulcrum, causing the user to tilt outward. In such cases, water pressure may be applied to the user as the lifting section rises, potentially causing the user to let go of the handle and fall. However, as described above, by setting the forward projection length of the scaffolding section to be greater than the forward projection length of the handle, it becomes possible to ensure that the user and the lifting section are approximately parallel when the user grasps the handle, thereby reducing the risk of the user falling.

[0015] The drive unit can be driven by the pressure of a liquid other than gas or oil. In other words, the drive unit has an air cylinder or a hydraulic cylinder, and because it is air-driven or hydraulically driven, even if air or water leaks from the cylinder, contamination of the water can be minimized.

[0016] The drive unit is configured to have a predetermined time lag at the beginning of the upward movement of the lifting unit, thereby ensuring that the user can maintain a posture that can withstand the upward movement before the lifting movement begins.

[0017] Since the drive unit is provided on the rear side of the main body, it is possible to install the drive unit without it protruding from the side of the main body.

[0018] By having an upward button for raising the lifting mechanism, the lifting mechanism can be raised by operating the button.

[0019] By positioning the aforementioned upward button so that it faces diagonally forward and outward, the button operation can be made even easier.

[0020] Furthermore, by adding a lowering button for lowering the lifting mechanism, the lowering operation of the lifting mechanism can be controlled by operating the button.

[0021] Furthermore, the down button is located above the lifting mechanism, allowing the user to descend after ascending using the lifting mechanism.

Advantages of the Invention

[0022] According to the present invention, by performing a lifting and lowering operation, it is possible to assist a user in ascending and descending.

[Modes for carrying out the invention]

[0024] Embodiments of the present invention will be described in detail with reference to the drawings. Figure 1 is a perspective view showing the configuration of the lifting device of the present invention, Figure 2 is a perspective view showing the lifting device in a raised state, Figure 3 is a front view of the lifting device, Figure 4 is an enlarged front view showing an enlarged view of the handle portion of the lifting device, Figure 5 is a side view of the lifting device, Figure 6 is a plan view of the lifting device, Figure 7 is another plan view of the lifting device, Figure 8 is a diagram showing the configuration of the lifting section of the lifting device, Figure 9 is another diagram showing the configuration of the lifting section of the lifting device, Figure 10 is a diagram showing the air supply system of the drive section of the lifting device, Figure 11 is a side view for explaining the effect of the lifting device, and Figure 12 is another side view for explaining the effect of the lifting device. In the following explanation, the side of the lifting device 1 with the handles 20, 30 and the platform 40 will be considered the front, the opposite side (poolside P3 side) will be considered the rear, the side from which the lifting device 1 rises will be considered the upside, the side from which it descends will be considered the downside, the right side when viewing the lifting device 1 from the front will be considered the right, and the left side will be considered the left, with each direction clearly indicated in the diagram.

[0025] Referring to these figures, the configuration of the lifting device 1 is outlined as follows: The lifting device 1 is a device used for raising and lowering user A when exiting pool P, and has a lifting unit 10, a first handle unit 20, a second handle unit 30, a platform unit 40, a drive unit 50, a first drive button 60, and a second drive button 70. The lifting device 1 is immersed in the water filling pool P. The lifting device 1 can be raised and lowered while immersed in water.

[0026] The lifting mechanism 10 operates in the vertical direction and is located on the inner surface P2 side of the pool P. The lifting mechanism 10 extends vertically along the inner surface P2 side of the pool P and can move up and down in the vertical direction.

[0027] The lifting unit 10 is housed within the casing 1A and has a plate-shaped lifting unit body 11 that extends vertically and moves up and down. The lifting unit 10 can move up and down independently of the casing 1A (the casing 1A remains fixed in position and does not move even when the lifting unit 10 moves up and down). The lifting unit body 11 has an elongated through hole 12 on its central side that extends from the middle of the vertical direction to the lower side. The casing 1A has a slit 1A' on its central side that extends vertically. The slit 1A' is provided to correspond to the through hole 12, and both the through hole 12 and the slit 1A' are sized to allow the core material B' of the course rope B to pass through. This allows the lifting device 1 to be installed straddling the course rope B. The casing 1A has an extension 1B that extends rearward from the middle of the rear side 1A3, and the lifting device 1 is fixed to the pool deck P3 via the extension 1B.

[0028] The first handle portion 20 is provided on the lifting portion 10 and can move up and down together with the lifting portion 10. The first handle portion 20 can be grasped by the user A with their hand. The first handle portion 20 is provided above the upper end 12' of the through hole 12 in the lifting portion body 11 so as to protrude forward, and is annular in shape. The first handle portion 20 is configured like a D-ring.

[0029] The first handle portion 20 has a right handle portion 21 provided on the right side of the front surface 11A of the lifting unit body 11, and a left handle portion 22 provided on the left side of the front surface 11A of the lifting unit body 11. As shown in an enlarged view in Figure 4, the first handle portion 20 is provided so as to be inclined outward from the top to the bottom, and the right handle portion 21 and the left handle portion 22 are provided in a roughly V-shape when viewed from the front.

[0030] The first handle portion 20 is attached to a plate-shaped mounting portion 20A. The mounting portion 20A has the first handle portion 20 attached to the front side 20A1 and a connecting portion 20B on the rear side 20A2, connecting the mounting portion 20A and the lifting unit body 11 via the connecting portion 20B. The width dimension of the connecting portion 20B in the left-right direction is within the width dimension of the slit 1A' of the casing 1A, and the connecting portion 20B is sized to fit within the width of the slit 1A'. The front end 20B' of the connecting portion 20B is provided on the rear side 20A2 of the mounting portion 20A, and the rear end 20B'' is provided on the lifting unit body 11. As a result, the first handle portion 20 can move up and down together with the lifting unit body 11 along the front side 1A1 of the casing 1A without obstructing the lifting operation.

[0031] The second handle portion 30 is provided on the upper surface 1A2 side of the casing 1A and is annular in shape. The second handle portion 30 is configured like a D-ring. The second handle portion 30 is not connected to the lifting portion 10 and its position is always fixed. After the user A is raised together with the lifting portion 10 by the drive unit 40, the user A can descend from the lifting portion 10 while grasping the second handle portion 30 with their hand.

[0032] The scaffolding section 40 is provided on the lifting section 10 and can move up and down together with the lifting section 10. The scaffolding section 40 can serve as a platform for user A. The scaffolding section 40 is provided on the lower side of the lifting section body 11 so as to protrude forward and can move up and down together with the lifting section body 11. For more details, the scaffolding section 40 is provided below the lower end 12'' of the through hole 12.

[0033] The scaffolding section 40 has a horizontally extending plate-shaped scaffolding section body 41, with the rear end 41A of the scaffolding section body 41 provided on the lower side of the lifting section body 11. The scaffolding section 40 has a spacer 42, and the scaffolding section body 41 is provided on the lower side of the lifting section body 11 via the spacer 42. As a result, the rear end 41A of the scaffolding section body 41 is spaced a predetermined distance forward from the front surface 1A1 of the casing 1A. Furthermore, the width dimension of the spacer 42 is within the width dimension of the slit 1A' of the casing 1A, and is sized to fit within the width of the slit 1A'. In other words, care has been taken to ensure that the scaffolding section body 41 and the spacer 42 do not become an obstacle during lifting and lowering operations.

[0034] Furthermore, the scaffolding body 41 is supported on its underside 41B by a support part 43. The support part 43 is a plate-like structure extending vertically and forming a roughly right-angled triangle. The width dimension (thickness) of the support part 43 in the left-right direction is within the width dimension of the slit 1A' of the casing 1A, and is sized to fit within the width of the slit 1A'. In other words, care has been taken to ensure that the support part 43 does not become an obstacle during the lifting and lowering operation.

[0035] Here, as shown in Figure 6, the forward projection length L2 of the scaffolding section 40 is set to be greater than the forward projection length L1 of the first handle section 20. This makes it possible to ensure that when user A grasps the first handle section 20, user A and the lifting section 10 are approximately parallel.

[0036] In other words, as shown in Figure 11, if the forward projection length L2 of the scaffolding section 40 is small, there is a risk that user A will tilt outward, with user A's feet acting as a fulcrum. In such a case, water pressure will be applied to user A when the lifting section 10 rises, and there is a risk that user A will let go of the first handle section 20 and fall. On the other hand, as shown in Figure 12, if the forward projection length L2 of the scaffolding section 40 is set to be greater than the forward projection length L1 of the first handle section 20, it becomes possible to make user A and the lifting section 10 approximately parallel when user A grasps the first handle section 20, thereby reducing the risk of user A falling.

[0037] Furthermore, as shown in Figure 7, the left and right lengths M1 of the scaffolding section 40 are set to be within the width dimension M2 of the course rope B. By setting the left and right lengths M1 of the scaffolding section 40 to be within the width dimension M2 of the course rope B, it is possible to reduce the amount of the scaffolding section 40 that extends beyond the left and right sides of the course rope B, thereby reducing the occurrence of problems such as users A tripping over the scaffolding.

[0038] Furthermore, the scaffolding section 40 is installed so as to be at least 90 cm below the water surface H of pool P.

[0039] The drive unit 50 can move the lifting unit 10 up and down. The drive unit 50 can be driven by gas pressure. That is, the drive unit 50 has an air cylinder 51 and can be air-driven. The drive unit 50 can be configured to have a predetermined time lag at the beginning of the upward movement of the lifting unit 10. By configuring the drive unit 50 to have a predetermined time lag at the beginning of the upward movement, it is possible to ensure that user A is in a position to withstand the upward movement before the lifting movement begins.

[0040] The drive unit 50 is configured to supply air from the air source 52 via a supply valve 53. By pressing the first drive button 60, the supply valve 53 opens, supplying air to the air cylinder 51 and driving the drive unit 50 to raise the lifting unit 10 (by pressing the second drive button 70, the exhaust valve 53A opens, exhausting air from the air cylinder 51 and driving the drive unit 50 to lower the lifting unit 10). A time lag can be created by delaying the time between pressing the first drive button 60 and opening the supply valve 53 (the drive unit 50 can be provided with an operation delay circuit to delay the time between pressing the first drive button 60 and opening the supply valve 53). The time lag can also be adjusted by simply adjusting the pressure of the air source 52. The air cylinder 51 can produce a desired time lag by simply adjusting the pressure, more so than a cylinder that uses liquid as a drive source.

[0041] The drive unit 50 is located on the rear side 11B of the lifting unit body 11. In other words, in the drive unit 50, the cylinder portion 54 of the air cylinder 51 is provided on the inner surface side of the casing 1A via a connecting member 57, and is not connected to the lifting unit body 11. On the other hand, the piston rod portion 55 of the air cylinder 51, which reciprocates in the vertical direction, is not connected to the inner surface side of the casing 1A, but is connected to the rear surface 11B side of the lifting unit body 11. As a result, the lifting unit body 11 can move up and down independently of the casing 1A by the drive unit 50, and its relative position to the casing 1A can be changed.

[0042] The air cylinders 51 are provided in parallel on the rear side 11B of the lifting unit body 11. The piston rods 55 of the two parallel air cylinders 51 are connected by a connecting member 56 so as to bridge each other.

[0043] In other words, in this embodiment, user A will step onto the scaffolding 40 from both the left and right sides and grasp the handles 21 and 22. As a result, a large force is applied to the piston rods 55 of the two parallel air cylinders 51 outwards in the left-right direction, which may cause the gap between them to widen as the cylinder rises. However, by connecting the piston rods 55 of the two parallel air cylinders 51 with a connecting member 56, it is possible to prevent the gap from widening.

[0044] The first drive button 60 is for driving the drive unit 50. The first drive button 60 is an upward button that drives the drive unit 50 to raise the lifting unit 10 (hereinafter, the first drive button 60 will be referred to as the upward button 60).

[0045] The lifting button 60 is located on the side of the lifting section 10 in the casing 1A. The lifting button 60 is positioned to face diagonally forward and outward. The lifting button 60 includes a right-side lifting button 61 that faces to the right and a left-side lifting button 62 that faces to the left. The second drive button 70 is for driving the drive unit 50. The second drive button 70 is a down button 70 that lowers the lifting unit 10 by driving the drive unit 50 (hereinafter, the second drive button 70 will be referred to as the down button 70).

[0046] The down button 70 is located on the upper side of the lifting section 10 in the casing 1A. The down button 70 is located on the upper surface 1A2 side of the casing 1A. Since the up button 60 and the down button 70 are located on the casing 1A, their positions are always fixed regardless of the lifting movement of the lifting section 10.

[0047] The lifting device 1 has a rear surface 1a that is spaced a predetermined distance from the inner surface P2 side of the pool P, forming a predetermined space S between it and the inner surface P2 side of the pool P. The space S is set to a size that allows the end portion 90A of the touch plate 90, which is provided on the inner surface P2 side of the front surface P1 of the pool P, to be inserted, and is not in contact with the touch plate 90.

[0048] The lifting device 1 configured as described above can be used as follows. In other words, user A places their feet on the scaffolding 40 and grasps the first handle 20 with their hands. Users A can step on the course rope B from both sides simultaneously. User A on the right side of the course rope B grasps the right handle 21 with their hands, and user A on the left side grasps the left handle 22.

[0049] Next, either user A on the right or user A on the left presses either the right-side up button 61 or the right-side up button 62. This activates the drive unit 50, causing the lifting unit 10 to rise from the lower position to the upper position, allowing user A to exit pool P.

[0050] After the lifting section 10 is raised, the user A on the right and the user A on the left descend while grasping the second handle section 30 with their hands. When either the user A on the right or the user A on the left presses the down button 70, the drive unit 50 is activated and the lifting section 10 descends from the upper position to the lower position. Thereafter, the users A can similarly move up and down using the lifting device 1.

[0051] As described above, according to this embodiment, the lifting unit 10 moves vertically and moves up and down along the inner surface P2 of the pool P, the lifting unit 10 is provided with a handle 20 that the user A can grasp with their hand, the lifting unit 10 is provided with a footrest 40 that serves as a footrest for the user A, and the lifting unit 50 is provided for raising and lowering the lifting unit 10. In this way, the lifting operation can assist the user A in moving up and down when they leave the pool P, for example, by having the user A place their feet on the footrest 40 and grasp the handle 20 with their hand, and then having the lifting unit 50 raise the lifting unit 10 so that the user A can leave the pool P.

[0052] Furthermore, the lifting unit 10 has a lifting unit body 11 that moves up and down, and the lifting unit body 11 is provided with a through hole 12 that extends in the vertical direction, and the through hole 12 is configured so that the course rope B can be inserted through it, making it possible to assist users A in exiting the pool P on both sides of the course rope B.

[0053] Furthermore, since the handle portion 20 is positioned to protrude forward, user A can easily grasp the handle portion 20.

[0054] Furthermore, the handle portion 20 has a right-side handle portion 21 provided on the right side of the lifting unit body 11 and a left-side handle portion 22 provided on the left side of the lifting unit body 11. As a result, a user A on the right side of the course rope B can grasp the right-side handle portion 21, and a user A on the left side of the course rope P can grasp the left-side handle portion 22.

[0055] Furthermore, the handle portion 20 is provided so as to be inclined outward from above to below, and the right handle portion 21 and the left handle portion 22 are provided in a V-shape, so that a user A on the right side of the course rope B can easily grasp the handle portion 20 from the right, and a user A on the left side can easily grasp the handle portion 20 from the left.

[0056] Furthermore, since the scaffolding section 40 is provided on the lower side of the lifting unit body 11 so as to protrude forward, user A can easily place their feet on the scaffolding section 40.

[0057] Furthermore, the drive unit 50 is an air cylinder 51, and because it is air-driven, even if air leaks from the cylinder, contamination of the water in the pool can be minimized.

[0058] Furthermore, the drive unit 50 is configured to have a predetermined time lag at the beginning of the upward movement of the lifting unit 10, thereby ensuring that user A can maintain a posture that can withstand the upward movement before the lifting movement begins.

[0059] Furthermore, since the drive unit 50 is located on the rear side 11B of the lifting unit body 11, it is possible to install the drive unit 50 without it protruding to the side of the lifting unit body 11, and the overall left-right dimensions of the device can be set to within the width dimension M2 of the course rope B. As a result, the overall width of the device can be reduced, and blind spots caused by the lifting device 1 can be reduced.

[0060] Furthermore, the rear surface 11B is spaced a predetermined distance from the inner surface P2 of the pool P, forming a predetermined space S between it and the inner surface P2 of the pool P. The space S is set to a size that allows the end portion 90A of the touch plate 90, which is provided on the inner surface P2 of the pool P, to be inserted. Since the lifting device 1 does not come into contact with the touch plate 90, it is possible to prevent interference with the time measurement function of the touch plate 90.

[0061] Furthermore, by having an upward button 60 for raising the lifting unit 10, the upward movement of the lifting unit 10 can be performed by operating the button.

[0062] Furthermore, since the upward button 60 is located on the side of the lifting section 10, it is possible to make button operation easier, such as allowing user A to operate the button from the side.

[0063] Furthermore, by positioning the upward button 60 so that it faces diagonally forward and outward, the button operation can be made even easier.

[0064] Furthermore, by including a lowering button 70 for lowering the lifting unit 10, the lowering operation of the lifting unit 10 can be performed by operating the button.

[0065] Furthermore, since the down button 70 is provided on the upper side of the lifting unit 10, user A can perform a downward operation after being raised by the lifting unit 10. (Previously, the up button 60 and down button 70 were combined and provided on the handle 20 to move up and down together with the lifting unit body 11, but this made it difficult to operate the buttons both when raising and lowering. In this embodiment, the up button 60 and down button 70 are separate components and further configured as described above.)

[0066] It should be noted that the present invention is not limited to the embodiments described above, and various modifications and applications are possible.

[0067] In other words, in the embodiment described above, the drive unit 50 is an air cylinder 51, but the desired effect can also be achieved by configuring it to be driven by the pressure of another gas that does not contaminate water.

[0068] Furthermore, the system may be driven by the pressure of a liquid other than oil. For example, the drive unit 50 may be a hydraulic cylinder, and the desired effect can be achieved by using hydraulic drive.

[0069] Furthermore, in the embodiment described above, the scaffolding section 40 is fixed in place, but it may also be configured to rotate left and right. In this case, the lifting section body 11 and the scaffolding section body 41 are connected via an axis, and the scaffolding section body 41 can be rotated around the axis.

[0070] Furthermore, in the above-described embodiment, the handle portion 20 is provided so as to be inclined outward to the side from above downward, and the right handle portion 21 and the left handle portion 22 are provided in a V-shape. However, as shown in Figure 13, the handle portion 20 can also be provided along the vertical direction, or as shown in Figure 14, along the horizontal direction, to achieve the desired effect. However, as described above, if the handle portion 20 is provided so as to be inclined outward to the side from above downward, and the right handle portion 21 and the left handle portion 22 are provided in a V-shape, then a user A on the right side of the course rope B can easily grasp the handle portion 20 from the right, and a user A on the left side can easily grasp the handle portion 20 from the left, making it a more preferable embodiment.

[0071] Furthermore, in the above-described embodiment, the left and right lengths M1 of the scaffolding section 40 are set to a dimension within the width dimension M2 of the course rope B. However, as shown in Figure 15, they may be set to be longer than the width dimension M2 of the course rope B. If the left and right lengths M1 of the scaffolding section 40 are set to be longer than the width dimension M2 of the course rope B, the scaffolding section 40 will protrude from both sides of the course rope B, but it will be easier to place your feet on it.

[0072] Furthermore, in the above-described embodiment, the upward buttons 61 and 62 are positioned to face diagonally forward and outward. However, as shown in Figure 16, they can also be positioned to face sideways, or as shown in Figure 17, they can be positioned to face forward, thereby achieving the desired effect. However, as mentioned above, positioning the upward button 60 to face diagonally forward and outward makes button operation even easier, resulting in a more preferable embodiment.

[0073] Furthermore, in the embodiment described above, the through-hole 12 is sized to allow the course rope B to pass through, and the user A is assisted in exiting pool P on both sides of the course rope B. However, the desired effect can also be achieved by providing the lifting device 1 without the through-hole 12 and without the course rope B in between, thereby assisting the user A in exiting pool P on both sides.

[0074] Furthermore, although the above-described embodiment has a right-side handle portion 21 and a left-side handle portion 22, the desired effect can also be achieved by using a single handle portion to assist only one user A in exiting the pool P.

[0075] Furthermore, in the above-described embodiment, the drive unit 50 is provided on the rear 11B side of the lifting unit body 11, but the desired effects can also be achieved by providing it on the side of the lifting unit body 11. However, providing the drive unit 50 on the rear 11B side of the lifting unit body 11 is a more preferable embodiment because it reduces the overall width of the device and minimizes blind spots caused by the lifting device 1.

[0076] Furthermore, in the above-described embodiment, the lifting device 1 is spaced a predetermined distance from the inner surface P2 of the pool P on its rear side, forming a predetermined space S between the lifting device 1 and the inner surface P2 of the pool P. The space S is set to a size that allows the end portion 90A of the touch plate 90 provided on the inner surface P2 of the pool P to be inserted, and is designed to be non-contact with the touch plate 90. Of course, if there is no touch plate 90, it is not necessary to provide the space S.

[0077] Furthermore, in the embodiment described above, the lifting device 1 is used for raising and lowering when user A leaves pool P. However, the lifting device 1 can also be installed on a ship and used for various purposes such as when user A boards the ship from a river, sea, swamp, lake, or pond, thereby achieving the desired effect. In addition, the lifting device 1 is not limited to raising and lowering while submerged in water and can be used for various purposes.

[0078] However, when the lifting device 1 is raised and lowered while submerged in water, and especially when user A is raised and lowered when leaving pool P, the various special effects described above can be achieved, and installing and using the lifting device 1 in pool P is a more preferable embodiment.
