Description

[Detailed explanation of the idea] The present invention relates to a lifting device for lifting a bathtub.

The device is designed to control at least one permanently mounted power actuator, such as a cylinder arrangement, by a member cooperating with two fixedly mounted guide members.
The bathtub is configured to be operatively connected to the tor unit.

An object of the present invention is to provide a bathtub lifting device which has a very simple structure and can operate the bathtub stably and well.

That is, the above object of the present invention is to substantially achieve a device for lifting a patient in a bathtub together with the bathtub so that the patient can wash himself from both sides of the bathtub. The device consists of a frame fixedly installed on the floor and two fixedly mounted spaced apart parts on the frame.
substantially vertical guide members, a vertically extendable power actuator fixedly mounted between the guide members, and vertically spaced apart vertically with respect to the guide members for reinforcing the top side surface of the bathtub; at least two guides having a flange portion and a bottom portion firmly connected to each other so as to be slidable along each guide member, and to be actively guided to move along the guide member so as to wrap around the guide member; A sleeve, a coupling carried by each guide sleeve and connected to the object, and a coupling for interconnecting the guide sleeves on each guide member and for guiding the guide sleeves to be at the same height on the two guide devices. and a framework connecting the sleeve to a vertically extendable power actuator.

Referring to the accompanying drawings, a frame 1, at least one power actuated device mounted on the frame 1;
2. Guide means having a substantially vertical guide member 3 on the frame 1; a coupling unit 4 cooperating with the guide member 3 for carrying the Buster Pro; a coupling unit for the power actuating device 2; Examples include a connection frame 5 connected to 4.

The frame 1 is fixedly installed on the floor, and is generally box-shaped and has a base plate Ha, and the base plate 1a has an upper portion 1b forming the top of the frame at the same height as the floor surface. It is installed on the floor so that

A side flange 1c projects upward from the upper frame portion 1b, and functions as a reinforcing member for the frame and also as a mounting flange for the guide member 3.

However, instead of a fixed device frame of this type, it is also possible to use a frame that is freely configurable relative to the floor (not shown) to carry the lifting device.

Preferably, a pressure cylinder 2a is used as the power actuating device 2, the pressure cylinder 2a having a piston 2b movable within it and a vertical movable shaft 2C projecting upwardly from the cylinder 2a. There is.

A chamber 2d of a cylinder 2a for receiving a working fluid in order to constitute a hydraulically driven (so-called hydraulic type) power operating device.
may be connected to the domestic water mains or to a separate pump.

Note that an electromechanical or electrohydraulic type power actuator may be used instead of the hydraulic power actuator.

In order to make the structure of the lifting device simple and stable and to avoid the risk of the movable parts being jammed, the sleeve 4a forming part of the coupling unit 4 is actively guided so as to enclose the guide member 3. It is configured to move along the guide member 3.

That is, at least two guide sleeves 4a are engaged with each guide member 3 so that a tensile load is applied to the upper sleeve supporting the edge of the bathtub, and a compressive load is applied to the lower sleeve, and each guide member 3 upper guide sleeve 4a
are vertically spaced from each other as shown in FIG.

Each guide sleeve 4a has a coupling unit 4 on the one hand.
a coupling 4 which is connected to a connecting frame 5 connecting the power actuated device 2 and which on the other hand forms part of a coupling unit 4;
connected to b.

Coupling 4 between power actuator 2 and coupling unit 4
In order to make the connection state between b stable and strong, both the connecting frame 5 and the coupling 4b are connected to the guide sleeve 4a.
are installed individually.

That is, each guide sleeve 4a interconnects the connection frame 5 and the coupling 4b.

As shown in FIG. 4, when each guide sleeve 4a constitutes a corner member between the horizontal bridging member 5a of the connecting frame 5 and the coupling 4b, the combination of the connecting frame 5 and the coupling unit 4 becomes particularly stable. Become.

If the coupling 4b is configured to protrude from the guide sleeve 4a so that the imaginary extension line of the coupling 4b intersects the guide member 3, there is an advantage that the load can be moved symmetrically.

For this reason, it is desirable to connect the connecting frame 5 to the guide sleeve 4a so that the virtual extension line of the horizontal bridging member 5a intersects the guide member 3.

In order to make the guide member 3 and the guide sleeve 4a robust and strong by making the dimensions and shapes of the guide member 3 and the guide sleeve 4a largely different, the guide member 3 is formed into a structure having a four-sided tubular cross section, preferably rectangular. and guide sleeve 4a
It is desirable to form the structure into a preferably rectangular structure having 44 faces.

Furthermore, it is preferable that the guide member 3 has a corner plate 3a having a sliding surface and a corner made of, for example, a thin stainless steel plate, and the guide sleeve 4a is connected to the corner plate 3a through a bearing member 4e made of, for example, a plastic material. Preferably, it is configured to cooperate with plate 3a.

These corner plates 3a and bearing members 4e enable the guide sleeve 4a to slide, and prevent restraint due to rust growth. It can be guided and slid.

As shown in the figure, the power actuating device 2 is disposed between the guide sleeve 4a interlocking with each guide member 3 and the guide member 3, and the guide sleeve 4a is a bridge of the connecting frame 5 disposed between the guide members 3. Due to the rigid connection to each other by the parts 5a, the lifting device is particularly well balanced with respect to the load.

Further, as can be seen from the figure, the horizontal member 5a is fixed to the lifting operation portion of the power actuating device 2, that is, the piston rod 2c.

Furthermore, as a further stabilizing factor, the outwardly facing side of the guide member 3 can also be joined to the inwardly facing side of the frame flange 1c, so that the guide member absorbs forward deflection stresses. I can do it.

The connecting frame 5 furthermore has a vertical member 5b located internally with respect to each guide member 3 and connected to a guide sleeve 4a which slides on the guide member 3.

As is clear from FIG. 1, the guide sleeve 4a is located at the same height in the two guide members 3.

Incidentally, since the power actuating device 2, the guide member 3, and the connecting frame 5 are arranged side by side, an extremely solid power bag for raising a large load can be obtained.

It should be noted that it is possible to change the number of members that make up the lifting device of the present invention and to change the design of the parts constituting the members without departing from the scope of the claims for utility model registration.

For example, in order to limit the upward stroke, the guide member 3
A stop member 3b can be provided at the upper end of.

Furthermore, it is also possible to vary the number of guide sleeves and couplings 4b.

Further, in order to enclose and protect the lifting device, it is housed in a casing 7, and the casing 7 is supported by a frame,
It is also possible to arrange a panel 8 (FIGS. 5 and 6) on the outside of this casing 7.

This panel 8 can also be fitted with a guide sleeve 4a to carry various necessary items such as sanitary equipment.

Next, talking about the bathtub, as shown in FIG. 7, the bathtub needs to have an extremely strong structure in order to attach the bathtub in the longitudinal direction to the lifting device.

Therefore, there is a solid flange on the upper edge of the bathtub that supports the flange and the lower part, and has enough support to support the weight of the bathtub, the hot water in it, and the patient at the same time. It's a bathtub.

The supports of the Bustapro are each connected to the guide sleeves via couplings of the lifting device.

The upper guide sleeve therefore receives a tensile load via the coupling, and the lower guide sleeve receives a compressive load via the coupling, and the spacing between the two force springs corresponds to the depth of the bathtub and is therefore somewhat narrower than the width of the bathtub.

Since the present invention is not intended for transportation, the frame is fixedly installed on the floor, and is therefore completely different from various transportation devices such as forklifts.

2 for raising a bathtub which is a large load object
a vertically extensible power actuator fixedly mounted between the guide members, and a vertically extendable power actuator disposed longitudinally spaced apart with respect to each of the guide members; at least two guide sleeves that are slidable along the member and move along the guide member in a manner that encloses the guide member while being actively guided; carried by the guide sleeve and connected to the bathtub; a power actuated coupling interconnecting the guide sleeves on the guide members and capable of vertically extending all the guide sleeves so that the guide sleeves are at the same height on the two guide members; Since the bathtub consists of a device that connects to the device, not only will the bathtub not tilt or sway even if the bathtub is lifted up with a patient in it, the patient can wash with peace of mind, and the nurse can A user can adjust the height of the bathtub to a convenient height and can nurse and wash the patient from both sides of the bathtub.

Therefore, it is highly desirable that the power-operated device uses a hydraulic or electric mechanism, and a device that is lifted by a rope is undesirable because accidents such as rope breakage occur.

Furthermore, it is not preferable to use gas pressure with a large difference in compression and expansion for power.

Since the present invention is used to raise a bathtub containing a patient who is most sensitive to shocks, great care must be taken in its design and manufacture.

The advantage of the present invention is, first of all, that it has a very simple and stable construction, and because of its simple design, it is possible to considerably reduce manufacturing costs compared to conventional similar products.

Furthermore, one longitudinal side of the bathtub faces the lifting device, the rigid flange of the bathtub upper reinforcement and its lower part are connected to the coupling 4b to maintain the bathtub horizontally, and the three sides of the bathtub have no connecting components. This makes it easier for Bustapro users to approach patients inside Bustapro.

This also means that there is an increased possibility of utilizing transfer devices to move the patient into and out of the bathtub.

Furthermore, the invention makes it easier to maintain the overall cleanliness of the equipment, which is an extremely important factor when the equipment is used in a sanitary facility.

Both the lift device and BustaPro do not have long protruding carrying arms, making installation and assembly easy.
Transporting and handling this unit is also easy and does not take up much space.
