Definitions
- the invention relates to a bathtub lifter for elderly and disabled, comprising a scissors, through which a seat plate relative to a Floor frame is height adjustable, a backrest connected to the seat plate, a teleleskopierbare lifting device, on the one hand with the Backrest and connected to the seat plate and on the other hand on the Floor frame is supported, and a drive device for driving the lifting device, wherein the lifting device comprises a driven wheel, with a Drive wheel connected to the drive device forms a transmission and can be brought into engagement.
- Such bath tub lifters are e.g. from document GB-A-2 234 491 and are generally available via a hand control panel controlled by a button to move up and down the seat plate comprises. Furthermore, with these bath tub lifters also provided an emergency off switch, which makes a movement of the seat plate immediately interrupts.
- a disadvantage of this known solution is that the seat plate their downward movement is not independent in a pinching a Body part of a bathing person interrupts.
- An object of the invention is to provide a known bath tub lifter form, that the downward movement of the seat plate by a force acting on the lifting device, from pinching a Body part of a bathing person resulting tensile strength functionally reliable, stopped quickly and independently. Furthermore, it is intended that the Bathtub lifter of the type mentioned in such a way that can be dispensed with costly electrical circuits and a particularly small footprint is required.
- This object is achieved in that the two gears by an acting on the lifting device, from pinching a body part of a person bathing resulting tensile force are separable from each other.
- This embodiment makes it possible to save space and function Clamp protection device to realize that no sensitive Includes electronic components.
- the invention also provides conveniently that the transmission as Gear transmission and in particular designed as bevel gear, wherein the output gear by means of a compression spring in engagement with the drive wheel can be brought.
- the gears transmit the rotational movements of a form-fitting Drive shaft of the drive device to an output shaft of the lifting device, which causes a height adjustment of the seat plate.
- the gears are separable from each other when the resulting from the pinching of a body part of a person bathing Traction is greater than that counteracted by the compression spring Compressive force. Controls or other electrical circuits are thus not required, since this clamp protection only mechanically acting Components includes.
- the lifting device is designed as a screw spindle drive and comprises a spindle outer tube, in which a lifting spindle with a spindle nut is provided, with the spindle nut, a spindle inner tube connected to a spindle foot.
- the output gear usually engages in the drive wheel one.

- the spindle foot in the spindle foot receptacle of Floor frame is fixed axially movable, with a contact plate with a Recess for the spindle foot covers the spindle foot receptacle.
- the Spindle foot includes an annular shoulder, which in one of the pinching a body part of a bathing person resulting, axial movement rests against the contact plate.
- a bathtub lifter is shown in its entirety. He embraces a floor frame 1 with feet 51, which on the bottom of a not shown Bath is laid. Furthermore, the bath tub lifter includes a seat plate 2 by a scissors 3 relative to the base frame. 1 is height adjustable. On the seat plate 2 is a pivoting backrest 4 articulated via a pivot joint 5. For raising or lowering the seat plate 2 is driven by a drive device 6 Lifting device 52, with its upper end 8 in a storage facility 9 is mounted on the back of the backrest 4, and with its lower End 10 is supported in the floor frame 1.
- scissors 3 each includes a scissor cross on each side of the floor frame first and the seat plate 2.
- Each scissors cross is by two in the middle of the cross by a pivot joint 11 interconnected struts 12, 13th formed, wherein the upper free end 14 of the strut 12 on a pivot bearing 15 of the seat plate 2 and the lower end 16 of the strut 13 at a Swivel bearings 17 of the bottom frame 1 are mounted.
- the free end 18 of the Strut 13 and the free end 19 of the strut 12 are via sliding shoes in Guide rails 20 of the seat plate 2 and 21 of the floor frame 1 sliding stored.
- the lifting device 52 comprises a lifting spindle 7, which has a longitudinal axis 22 and a trapezoidal thread 23 has.
- the lifting spindle 7 carries a spindle nut 24 with a trapezoidal internal thread, which is in a spindle inner tube 25 protrudes and is firmly connected to this.
- the spindle inner tube 25 surrounds the lifting spindle 7 and one in the spindle inner tube 25 protruding portion 26 of the spindle nut 24.
- the spindle inner tube 25 forms the lower end 10 of the lifting device 52 and has a spindle foot 27 which, in a spindle foot receptacle 28 of the bottom frame 1 is supported.
- the lifting device 52 further has a spindle outer tube 29, surrounding both the spindle nut 24 and the spindle inner ear 25, wherein the spindle nut 24 with a ring portion 30 on the inside of the spindle outer tube 29 is applied to a rotational relative movement between the lifting spindle 7 and the spindle nut 24 to effect.
- the lifting spindle 7 has a cross-sectionally tapered spindle pin 31.
- the spindle tap 31 is rotatably connected to a driven gear 32, which with a Drive wheel 33 of the drive device 6 is engaged.
- the drive wheel 33 is rotationally fixed by a drive shaft 34 of the drive device 6 supported, wherein the drive shaft 34 has a longitudinal axis 35, the perpendicular to the longitudinal axis 22 of the lifting spindle 7 extends.
- the drive wheel 33 and the output gear 32 together form a bevel gear 50.
- the Diameter of the gears 32, 33 are identical.
- a receiving sleeve 36 inserted, which by one at the front side the spindle outer tube 29 adjacent annular projection 37 in position is fixed.
- the annular projection 37 opposite end of the receiving sleeve 36 is provided with an annular bottom portion 38, which fixes a helical compression spring 39 axially.
- the other end of the Compression spring 39 is in a receiving gap 40 of a further receiving sleeve 41 received adjacent to a voltage applied to the output gear 32
- Rolling bearing 42 is mounted.
- the two receiving sleeves 36, 41 are spaced from each other.
- the rolling bearing 42 is through the Output gear 32 and pushed by a on the spindle pin 31 Fixing disc 43 fixed in position, wherein the fixing disc 43 at the transition from the spindle pin 31 to the lifting spindle 7 is present.
- the force generated by the lifting device 52 is achieved by a clamping ring 44 applied to the seat plate 2 to be adjusted, with the spindle outer tube 29 is positively connected.
- the Clamping ring 44 mounted pendulum.
- the spindle root 27 has a conical shape Cross-section on.
- the spindle foot 27 is supported by its tip on a base 45 of the spindle foot receptacle 28 from that in the bottom frame 1 is formed.
- the spindle foot receptacle 28 includes a bearing plate 46 with a recess 47 for the spindle base 27.
- the investment plate 46 is spaced from the base 45 and covers the spindle foot receptacle 28 off.
- the spindle foot 27 has an annular shoulder 48, whose diameter is greater than the diameter of the recess 47.
- the Drive shaft 34 is by the preferably battery-powered drive device 6 driven.
- the drive wheel connected to the drive shaft 34 33 is thus also driven and transmits that through the Drive device 6 applied torque to the output gear 32, which is rotatably mounted on the spindle pin 31, whereby the lifting spindle 7 is rotated.
- the spindle pin 31 and the lifting spindle 7 are to be regarded as the output shaft.
- the rotation of the lifting spindle 7 causes an axial movement of the spindle nut 24.
- the spindle nut 24 is also connected to the spindle nut 24
- Spindle inner tube 25 is shifted, whereby the with the spindle outer tube 29 connected via the clamping ring 44 seat plate 2 in height is adjusted.
- the output gear 32 is due to the spring force of Compression spring 39 in engagement with the drive wheel 33.
- On the Hubspindel 7 is a arranged in a spindle journal 31 adjacent portion Security nut 49 provided. It serves as a security element Breakage of the spindle nut 24.
