Description

lift

Technical area

The invention is based on a lift, which overcomes terrestrial obstacles and is also suitable for swimming pools, according to the preamble of the first claim.

State of the art

Since the invention of the Otis 1853 safety precaution, confidence in elevators has been strengthened and a large number of patents relating to elevators have been filed, with corresponding lifting and safety mechanisms, and with and without counterweights as described e.g. in US 2,086,002.

Lifts are also known in the form of stairlifts or as inclined lifts, such as FR 2877656. Furthermore, for swimming pools especially for disabled solutions have been created so that they also benefit from swimming, as described, inter alia, in the US 7275272 B2, US patents 4283803, US 5432961.

Presentation of the invention

The invention is based on a vertical or oblique lift in the terrestrial area for the transport of goods and people and for the swimming pool area for persons with reduced mobility, such as, for example, Seniors or mothers with their toddlers, but also for athletes, i. for recreational use, sports and rehabilitation, the lift system in the water by means of buoyancy is also possible self-supporting, according to the preamble of the first claim.

The duty in public facilities to ensure barrier-free access to the swimming pool, but also to use the swimming pool as widely as possible in the private sector, a swimming pool lift is an efficient solution to get people in or out of the water too

transport and a pleasant facility to simultaneously serve as a carrier of fitness and other equipment or as a diving tower.

The inventive approach is to operate such a system for terrestrial as well as for the swimming pool area with identical parts as possible, with a simple drive and a Sicherheitspospositiv, which excludes a crash of the lift platform in any case and this in an emergency, even without electricity, can drive in the best stroke position.

The safety aspect therefore includes in addition to the machine standards regarding

Safety distances to prevent any limbs from being pinched, covers to prevent shearing, a spring-loaded safety cable, a gas spring or a hydraulic accumulator or a battery-powered back-up solution, as well as a buoyancy body or airbag-like emergency buoyancy system in the swimming pool area. This ensures in case of failure of the drive that the platform of the swimming pool lift can never fall down or in case of electrical failure, by pressing a pressure switch, the hydraulics can be unlocked and due to the gas spring force or integration of the hydraulic accumulator, or by sufficient buoyancy on the float or gas filling a folded plastic bag, which inflated forms a buoyancy cushion and thus the platform can be moved to the desired position.

Furthermore, load-bearing structures in indoor swimming pools are extremely rigorous

Security regulations imputed, which leads to far beyond the quality of Standard stainless steel, so that higher quality and thus very expensive stainless steel is to be used. Therefore, the platform is underlaid by floats, so that in the corrosive environment of chlorine-containing air in a pool, in case of material failure, the platform can not quickly dive down and so not to meet a swimmer unhappy, but would then slowly sink like a leaking raft in the water , For this reason, a low-cost stainless steel such as according to the DIN standard 1.4404 or 1.4462 can be used.

For the terrestrial area, although the water element and thus the use of buoyancy bodies, but by means of a corresponding rope barrier or double guide of a rope, such required safety can be very well followed.

The drive can be identical to the swimming pool lift without a complex one

To ensure gear ratio, by means of a large Seilaufwickeltrommel and thereby frictionally attached small Seilaufwickeltrommel excellent translation of the drive, driven by a linear drive, such. a hydraulic cylinder, with a small stroke or a small hydraulic motor. The lifting cylinder, as well as a rotating motor, may be electrically or also by means of a fluid, e.g. Bio-oil or clear water, operated.

A hydraulic motor or an electric motor requires an additional lock to secure the angular position of the motor shaft. In contrast, a hydraulic cylinder only needs a load-holding valve to hydraulically lock the position of the piston rod.

By means of a pulley and a cable drum that multiplies

Transmission ratio and acts as a kind of power pulley. According to the invention, this is achieved by the features of the first claim.

The core of the invention is, by means of a reducing cable drum drive and attached to guide rods lift platform to make them crashproof by means of safety rope and a back-up system or and a solid or inflatable buoyancy body, as well as the entire drive of the platform lifter with reduction, hydraulic unit and control in to integrate the big cable drum.

Way to carry out the invention

Fig. 1 shows a schematic side view of a swimming pool lift 1 at one with

Water W filled swimming pool 2 with guide rails 3 and guide rollers 4 on the lift platform 5, an external drive 6 on the guide rail 3 with a buried cable 7 or a replaceable battery pack 8 and the cable drum 20, attached to the drive 6, is connected to the cable 9 connected to the lift platform 5 and the lift platform 5 has a buoyancy body 10, in which a swimming pool cleaning system 11 is inserted or this is fixed in a separate container 12 to the swimming pool wall 13 and a separate

Buoyancy body 10a is located on the guide rail 3.

Swimming pool 2 are not designed to accommodate a pool lift 1. In addition, the legal requirements regarding load-bearing constructions are rigorous, since intercrystalline corrosion can form in the chlorine-containing water and such a part breaks away without warning and rusting, and thus fatal

Can have consequences. Many private swimming pools 2 are not very suitable for holes with tensile fastenings, especially if they have a cover. This limitation greatly reduces the possibility of using such a swimming pool lift 1 at a low price. This is unfortunate since it involves many of the less mobile persons, e.g. Seniors, mothers with their toddlers or handicapped people, continue to struggle to get out of the water.

A swimming pool lift 1 is certainly the optimal device for this purpose and, if the kinematics permit it, can even be raised above the swimming pool wheel and thus used as a diving tower or sports equipment can be attached to it. Such a swimming pool lift 1 can also serve as a basis for various

Sport activities serve, such as Aquabiking or aquaring by allowing the person to individually drive the swimming pool lift 1 deep into the water until the most comfortable or most effective underwater position for the fitness program has been reached.

Such a swimming pool lift 1 is usually a large device, as more than one person wants to stand on such a platform or a wheelchair plus a helper must have space on it. In addition to the own weight and the people on it, this requires a considerably strong lifting motor or working cylinder. The innovative solution is the net weight of the swimming pool lift 1, as well as the built-in accessories by means of a buoyant body 10 in the water to reduce massively, so that the lifting motor or active cylinder still has to move a high load due to the translation described here, but for less speed, resp. less stroke is required on the effective cylinder.

Furthermore, the space required for such a swimming pool lift 1 should be used optimally, such as e.g. described above as the basis for sports equipment, but not only, but at the same time as a means for cleaning and disinfecting the swimming pool 2 in the form of a swimming pool cleaning system 11. Thus, a swimming pool 2 does not need separate premises and wall ducts on the pool 2 to keep the water pure. The direct exchange of contaminated water by means of an inlet at the skimmer 14, which has a coarse filter for leaves and others, to the circulation pump 15, then to the filter 16 and finally addition of chemical agents, such as e.g. Chlorine as a disinfectant, by means of a dosing device 17, which also flocculants etc the water W at a given time, either timed or by command from a water quality probe or disinfection of the water W by means of chemical UV light etc, thus has a short cleaning path, relieves the Circulation pump 15 and thus saves electricity, and improves the overall circulation in the swimming pool 2. If the space in the buoyant body 10 is fully required for the drive 6, as shown in Fig. 2, the pool cleaning system 11 can be housed on the wall of the swimming pool 2 in the container 12 become. This can be connected to the guide rails 3 instead of on the wall and serve with the corresponding volume of the container 12, at this point as a further buoyant body 10a.

In addition to the possibility of the swimming pool lift 1 as a carrier for the

To use pool cleaning system 1 1, the pool lift 1 can also be used as a sports tool, as described in Fig. 2, where the lift platform 5 can be raised above the edge of the swimming pool 2, so as to form a diving tower. Instead, from the lift platform 5 a

Ausklappsprungboard 63 are tilted up, which also forms a diving tower. The tipping can be done manually or electrically or hydraulically. At Ausklappsprungbrett 63 can also attach a waterfall and a corresponding LED lighting, creating a special ambience. The outside deck platform 60 shows an electric drive 6. Should this outside and behind the pool 2 are, this can also be operated with alternating current, which on the handrail 3a, part of the

Guide rail 3 is attached. Not shown is a variant of a reduction of the engine speed by means of a planetary gear or the variant as shown in Fig. 2-4. The lock of the stroke is done by means of the lifting lock 18 automatically or can also be operated manually and has a crank opening 19 so that in a technical breakdown by means of a hand crank the lift platform 5 can always be lifted. The drive 6 is the cable drum 20 to which the cable 9 is attached and this, deflected by means of the guide roller 21, is fastened to the lift platform 5 by means of the cable end 9a. The rope 9 may also be a flat belt, which has the advantage that the strands are juxtaposed and coated with plastic, thus corrosion can be virtually ruled out and the bending radius of the pulleys 21 can be made smaller.

The lift platform 5 has guide rollers 4, which surround the guide rails 3. The buoyant body 10 is attached to the lift platform 5 and includes the pool cleaning equipment 11, which has a watertight lid 22, so as to always provide access to the underlying technology, e.g. for filter replacement is possible. Is the pool cleaning system 11 on the wall of the

Swimming pool 2 housed in the container 12, so there is a cover 22 for inspection and service of the system available.

The buoyancy body 10 can not compensate for the full weight of the swimming pool lift 1 with the lift V, because then the lift platform 5 would not be lowered. The drive 6 thus always has to provide a residual force to lead the lift platform 5 upwards. For emergency, as shown in Fig. 3, a gas spring 44 can be additionally attached to the drive 6, so that it is always guaranteed that even with a hydraulic or electrical defect, the lift platform 5 completely, incl. with a person, can be lifted.

Alternatively, under the lift platform 5 an air bag 55 with a compressed

Filler 56 may be attached, which is opened in an emergency by means of the manual valve 57 and thus the filler 56 flows into the air bag 55 and this inflates and forms a buoyancy body 10, which lifts the lift platform 5. Such an air bag 55 with 200 L volume thus gives a lift of about 200 kg, enough to lift the lift platform 5 and one person easily over the waterline WL.

The container 12 is equipped with a buoyancy volume and acts as

Buoyancy body 10a and thus turns load from the edge of the swimming pool 2 from. Likewise, the buoyant body 10b on the guide rail 3 serves as an additional

Buoyancy, so that the load to the bottom of the swimming pool 2 can be kept low.

In order to reliably control the stroke H of the swimming pool lift 1, e.g. attached to the cable drum 20, a sensor 24 which detects the position of the lift platform 5 by means of the controller 25 and anfährt the corresponding desired positions. If the lift platform 5 is in position B and if the float wants to be lifted to the edge of the swimming pool 2 into position A, such a stroke control and control is advantageous. Furthermore, the position C can be approached elegantly and again back to the position A, so that the lift platform 5 can be used in between as a diving tower, or others

Activities associated with it, then again to take the neutral position, i. Position A. If the lift platform 5 is in position C, the skimmer is indeed out of the water, the water circulation and cleaning of the swimming pool 2 is ensured by means of the skimmer tube 14a.

With a long-term position attitude, in particular in position C, it could be that the lift platform 5 could lower over time, if no mechanical lock is attached and activated. By means of the controller 25, the actual / setpoint is automatically checked again and again. In case of a deviation above a certain value, the lift platform 5 is again brought to the desired value.

Instead of a drive 6 with alternating current and buried in the ground cable

7, the swimming pool lift 1 can also be used autonomously by the swimming pool lift 1 a replaceable battery pack 8 is attached, at the same time a Akkupacket 8 loads on a charging station not shown here in the house and so is always a fully charged power source available, which corresponding strokes and other Services, such as LED lighting or long operation of a circulation pump with one battery charge. Of course, the battery pack 8 can also be recharged by means of a solar system.

The guide rails 3 need not be aligned vertically, but can also be installed at an angle - with the appropriate adjustment to the guide rollers 4 - to a better pressure distribution on the guide rails 3 allow, or for certain devices on the lift platform 5, which require more distance from the wall of the pool 2 when diving and the like. The drive 6 can also be installed in the container 12, in which case the drive 6 and the cable drum 20 are rotated by 90.degree .. This also applies to the terrestrial version.

Fig. 2 shows a schematic side view of a swimming pool lift 1 at one with

Water W filled swimming pool 2 with guide rails 3, a collar 26 and Führungsgleitbuchsen 4a on the lift platform 5, a buoyancy body 10 housed platform lifter 60 based on hydraulic, consisting of a

Hydraulic cylinder 27, pump motor 28, valves 29, tank 30 and memory 31, and a Seiltromme translation 33, consisting of a large cable drum 33a and a small cable drum 33b, both of which may have divergent traction means. The cable drum translation 33 may have a connecting rod 34 to the other side of the lift platform 5, where also a rope 9 with the

Guide rail 3 is connected. The Hubsicherung upward is ensured by means of a releasable adjusting ring 26, the retaining fuse 35 is secured to the cable 9 by the brake 36 and the spring 37. The power supply to the pump motor 28 by means of an inductive contact 32nd

The lever logic of the lift platform 5 for this swimming pool lift 1 is different from the variant described in FIG. 1 in that the buoyancy body 10 is made large-volume, so that it can lift the lift platform 5 as well as the payload at any time with its buoyancy V via the neutral position A out to position C. Therefore, the rope 9 is attached to the lower part of the guide rail 3 at the cable end 9a and the hydraulic cylinder 27 pulls the lift platform 5 down to eg to move to position B, or lets the rope 9 - as a braking means - go slowly until the position C or any intermediate position is reached. The hydraulic cylinder 27 thus works only to bring the lift platform 5 down, in the opposite direction, upwards, this works only as a hydraulic brake. The hydraulic brake can also be an energy

Have Rekuperationsmittel, so that at least part of the braking power is converted into electricity and is available for the lifting and other services. A mechanical brake 36 presses by means of the spring 37 directly to the guide rail 3 and holds in the swell the lift platform 5 in the desired position. An unwanted startup of the lift platform 5 in the water is due to the strained rope 9 is therefore not possible, but in strong waves, the lift platform 5 could sink into a corresponding trough. This would relax the rope 9 and at this moment the brake 36 holds the retaining fuse 35 and holds the lift platform 5 firmly. In a smaller swimming pool 2, the waves do not work so that the lift platform 5 would sway, but in a hotel resort with a built into the sea facility or on a raft this backup is advantageous. Of course, the retaining fuse 35 can be operated manually at any time and thus the lift platform 5 are deliberately locked. The assurance that the lift platform 5 always goes up, even in the case of an electrical breakdown, it is therefore intended that the hydraulic system can be depressurized and thus the

Lift platform 5 always moves up to the collar 26. This serves for

Ensuring that the lift platform 5 does not continue uncontrolled upward, but can be solved so that the lift platform 5 continues to drive up to position C if necessary. The memory 31 serves to allow several full strokes H to be made up and down before the pump motor 28 has to be switched on again. The power supply to the pump motor 28 can be supplied by means of a suspension cable from land or by means of a power cable in the cable 9 as described in FIG. 5 by way of example or by means of an inductive

Contact 32. Transformer 32a turns AC direct current, e.g. 12V or 24V.

In order to optimally move the lift platform 5 with the guide bushes 38 shown here, which may have a plastic coating or ball bearings or rollers, a second cable 9 is attached to the opposite guide rod 3 and fastened to the opposite cable drum 20 and the two cable drums 20 connected to the transverse connecting rod 34. In this way, both cable drum 20 act synchronously.

Ideal is the end of the rope 9a at the lowest point, resp. Hubstelle at the

Guide rail 3 to have the electric or hydraulic drive under the

Lift platform 5 in the buoyancy body 10, wherein the cable drum 20 with the

Cable drum translation 33 can be placed vertically or horizontally. The rope 9 thus remains firmly in place and thus causes no scrubbing on the

Guide rail 3, only the cable drum 20 rotates and changes the altitude of the lift platform. 5 The guide rail 3 may be round or angular and may have a recess in which the cable 9 is thus not prominent recessed.

Fig. 3 shows a schematic side view of a terrestrial lift a on a

Obstacle 46, with guide rails 3, guide bushes 38 on the lift platform 5 and a platform lifter 60 by means of the hydraulic system 39 in a covered Geiänderseite 40 with emergency control 41 and motorized doors 42, and a gripping the lift platform 5 from below by means of a rope 9, which of two transverse rollers 43 is guided, and a gas spring 44 parallel to

Hydraulic cylinder 27 and a safety pin 49 and a hinge 50th

On the guide rail 3 is the terrestrial lift 1 a, which has the same components as the swimming pool lift 1, only the arrangement diverges by in one of the two railing sides 40, which also serves as a handrail and security from falling out in the there mounted cover 45 of the platform lifter 60 is attached to the hydraulic system 39. On the lower side of the lift platform 5 are located on the left and right each have a transverse role 43. The rope 9 goes from the large cable drum 33a, via the guide roller 21 and the two

Transverse rollers 43 transverse to the other side of the rope end 9a, which is located on one of the two guide rails 3 and thus has at the same time one

Fiaschenzugwirkung. Thus, the lift platform 5 can be moved vertically, easily and synchronously on the guide bushes 38 with a single rope 9 anyway, since the rope forces in the looping of the lift platform 5 are equally distributed. Instead of a handrail 3a, this part serves as a door support 47 and the anchoring of

Guide rail 3. The doors 42 can be positively controlled or motorized, e.g. open and close by means of a door cylinder 48.

The general concern of a rope break and a sticking between the outputs, is solved by either a retaining fuse 35 is attached as described in Figure 2 or a locking pin 49 is there that in case of a defect of the rope 9, for example, at almost every point in the Guide rail 3 engages, either activated by the missing rope 9, or electronically activated, by means of acceleration detection by an acceleration sensor. The fear of getting stuck in an uncomfortable height above ground is solved by the hydraulic system 39 has a memory 31, operated by means of the emergency control 41 manually by means of a Bowden cable 41 a, the valves 29 can be, while the safety pin 49 is released again and the lift platform 5 can be moved up or down, even several times, depending on the size of the memory 31. As an alternative, there is the possibility of the liftplatform 5 by means of the gas spring 44 in a certain stroke direction drive, in this case, the hydraulic system 39 is set to depressurized and also the safety pin 49 pulled, so that the lift platform 5 light and free of braking, but with a

predetermined stroke speed can be moved to a predetermined position. The lifting speed results from the nozzle opening in the gas cylinder 44 and thus defines the piston speed, as well as from the hydraulic cylinder 27 with respect to cross section of the hydraulic line, where the oil from the piston of the

Cylinder chamber is passed into the tank 30.

In the case of a terrestrial lift a, the placement of the electric drive 6 or a hydraulic system 39 at different locations is possible, up to the full-cabin equipped installation, where such a drive 6 or hydraulic system 39, the controller 25 can be attached to the ceiling of the cabin the full cab can provide more passenger seats, the floor is wheelchair accessible, and the terrestrial lift 1 a does not require a pit. Furthermore, at the joint 50, a staircase, not shown here can be mounted with horizontal position constant stages. shows a schematic side view of a hydraulic platform jack 60 with an inte-grated hydraulic system 39, cable drum 20, cable drum translation 33, hydraulic cylinder 27, controller 25, and power connection by means of inductive contact 32, and bearing 54, hinge 52, screw 53rd

The heart of a compact swimming pool lift 1 or a terrestrial lift 1 a is the accommodation of the electric or hydraulic platform lift 60, which does not restrict the user and is also easily accessible for servicing. Mechanical translations, in particular those by means of gears, are generally expensive, but not if a large cable drum 33a mounted on a base plate 51 is selected, which serves for winding and unwinding the cable 9 and next to which a smaller cable drum 33b is centrally mounted, on which another rope 9 is also wound up and unwound, wherein the rope 9 can also be a flat belt 99. This flat belt 99 is inserted at a flat belt end 9 d in the cable drum 33 b and with the other end 9 c with the

Hydraulic cylinder 27 connected. The rope 9 is on the one hand at the end of the rope 9b connected to the large cable drum 33 a and with the other end of the rope 9a at the Guide rod 3. The different diameters of the cable drum 33 a, 33 b result in the cable drum translation 33. The advantage is that by an exemplary stroke H of 250 cm with a swimming pool lift 1 or a

bridging the terrestrial lift 1a, a diameter of the large cable drum 33a of exemplarily 60 cm and the small cable drum 33b of 6 cm can be selected, this results in a transmission ratio of 1:10 and thus the piston stroke K of the hydraulic cylinder 27 is only 25 cm. The accommodation of such a small hydraulic cylinder 27 can thus be done within the large cable drum 33a, as well as the compact hydraulic system 39 as they are successfully used in large series of mobile equipment of earthmoving machines and trucks for lifts, it still finds space. In addition, a memory 31, as well as the controller 25 for a smart logic such as e.g. Pulse width modulation and control of the door cylinder 48 are housed therein. On the base plate 51, which may be mounted horizontally or vertically, can also integrate the connection for the power supply or as an element to which an inductive contact 32 can be mounted The storage of the cable drum 33a, 33b by means of the common bearing 54, which act on the small cable drum 33b or on the large cable drum 33a. This little space is claimed, but the cable drum translation 33 is compact and inexpensive stored. The base plate 51 may also be part of the cover of a swimming pool lift 1 or a terrestrial lift 1 a and by means of hinges 52 and Versch robbing 53 for servicing purposes removed or expanded. a schematic side view of a platform lifter 60 with integrated hydraulics, with the cable drum 33a, 33b, the pulley 58, controller 25 and the

Power flow through the current-carrying cable 59.

The construction corresponds to the version shown in Fig. 4, with the exception that by means of a pulley 58, here with 2-fold translation, whereby a higher gear ratio is possible, starting from the number of used

Pulleys 21, the pulley 58 a current-carrying cable 59 is attached. This has the advantage that at one end of the live lead 59, a fixedly installed distribution manifold 61 can be mounted, which e.g. the

Swimming pool cleaning system 1 1, LED lighting, pump motor and other electrical consumers operated and on the opposite side a simple Stromeinspeisung 62 directly into the current-carrying cable 59 allows. This simplifies the laying of the live cable 59 in addition, since the current-carrying cable 59 is no rotational movement, but a translation and the cable 9 at the same time up and can be unwound without this would have a power tap in the rotating part of the cable drum 33a result. Such a design thus elegantly generates a power pulley, ie the ratio of the pulley 59 multiplied by the ratio of the cable drum translation 33th

Fig. 6 shows a schematic side view of a terrestrial lift 1 a at one

Obstacle 46, with guide rails 3, guide bushes 38 on the one

Lift platform 5 and a platform lifter 60 is located in a covered housing 64, as well as a double platform 65, each with two sides

Swing lever 66 and a stop plate 67th

Such a construction is advantageous where no pit can be created or for cost reasons and optical reasons, no side housing 64 is to be mounted and no roofing of the lift platform is possible, in which then the platform lifter 60 could be integrated. One possibility is the platform lifter 60 at the front, i. to the wall of the obstacle 46 to install. Due to the fact that the platform lifter 60 is a certain size and volume, no matter what kind of translation means is mounted therein, such a platform lifter 60 in a housing 64 would obstruct the entry and exit at the upper level to the lift platform 5. Lowering the housing 64 so that it would be upright with the lift platform 5 would mean that, when lowering the terrestrial lift 1a, the lift platform 5 could not be completely lowered to the ground, since the housing 64 would first come into contact with the ground and would block another hub H.

To solve the problem, a second platform, a double platform 65, is placed over the lift platform 5. The double platform 65 is connected to the lift platform 5 by means of a set of pivot levers 66 acting as a parallelogram. The corresponding bearings are not displayed, as these represent the prior art with respect to a pivot bearing. The rope 9 which is fixed to the platform lifter 60 and wound thereon, causes the pulley 21 is pulled up at train due to the wrap around the guide roller 21, the double platform 65 to the stop on the housing 64, then the whole, ie the Double platform 65, lift platform 5, housing 64 and platform lift 60 to the upper Level up, which corresponds to the position A. The deflection roller 21 is ideally mounted on the pivot lever 66 and at the same time on the double platform 65. The upper part of the housing 64 is a walk-in area for persons and wheelchairs and the like. The lower part of the housing 64 is the boundary to the bottom 68. The housing 64 has left and right bumps 64 a, in which the

Guide bushes 38 are mounted and the corresponding pulleys 21. In addition, the platform lifter 60 is embedded in the housing 64.

In this way, people can safely move from the upper level horizontally to the lift platform 5 or vice versa, as well as a wheelchair without

Obstacle to be pushed straight ahead.

In the lowermost position, the housing 64 with the lift platform 5 first rests on the floor 68, and with the loosening of the cable 9, the pivoting lever 66, which holds the double platform 65, pivots with the simultaneous loosening of the loop around the guide roller 21 the double platform 65 on the lift platform 5 from. Rubber damper, between double platform 65 and lift platform 5, not shown here, feather lowering feathers elegant and quiet. In this way, persons or a wheelchair can leave the terrestrial lift 1 a comfortably, without leaving a high and disturbing paragraph or go without a problem on the double platform 65.

In addition, a stop plate 67 acts on the double platform 65. Such securing means are known in the case of wheelchair access lifts and fold out, lock themselves automatically as soon as the system has left the floor 68. Of course, a corresponding door 42 can be attached to the terrestrial lift 1 a, as well as to the upper level, position A.

Fig. 7 shows a schematic side view of a terrestrial lift 1 a at one

Obstacle 46, with guide rails 3, a platform lifter 60 in a covered housing 64 with bumps 64a, at which a movable double platform 65 with a stop plate 67 is located

The lifting principle can be compared with the inFig. 6, wherein in this variant the lift platform 65 is missing and the pivot arms 66 are attached to the boss 64a. The pivot arms 66, which act as a parallelogram, have practically a symmetrical Hubartikuiierung, so that the double platform 65 in the lower position on the bottom 68 practically bottom of the housing 64 abuts, as also abuts the top of the housing 64 as soon as the double platform 65 in the upper level, the position A is stopped. The bumps 64a are also mounted on the extreme left and right of the housing 64 and thus do not restrict the passageway.

Of course, the invention is not limited to those shown and described

Embodiments limited.
