An armchair (3) of a chairlift has a footrest (6) which is connected to an automatic positioning mechanism (17) and positionable below the seats (5) of the chair (3) between a driving position and an entry / exit position.
Austrian Patent Office AT 510 521 B1 2012-12-15
Description: [0001] The invention relates to an armchair of a chairlift having at least one seat having a seat, with a guard bar extending transversely across the seat and pivotable from an open position to a closed position, and with at least one footrest, wherein the Footrest is connected to an automatic positioning mechanism and adjustable below the seat between a driving position and an entry and exit position, and wherein the footrest is connected via pivoting rods with the chair.
Such a chair is known for example from US 2,710,650 A. Armchairs for chairlifts have at least one seat, often two, three or four but also up to eight or more, for example, ten, side by side seats, each seat being associated with a footrest on which the passengers may fasten their feet, if necessary with them Skiing or a snowboard, set up and support (eg AT 411 523 B, AT 411 046 B). The footrests are rigidly attached to the guard bar of the chair via support bars that extend down from the guard bar in front of the seats. The footrests themselves consist of laterally projecting away from the support rod rods or tubes, which are attached to the lower end of the support rods, and are brought by pivoting the guard in the entry or exit position.
A problem when pivoting the guard is that the support bar on which the footrest is arranged, a leg of a passenger can pinch when the passenger is not in its proper seating position. This problem is critical if the passenger wants to correct the seating position, since then there is a risk that he slipped off the seat. It may also be that he has to stay in an uncomfortable sitting position if he can not correct it.
Solution approaches in which a passenger closes the guard even after he is in a proper seating position are disadvantageous, since there is a risk that the guard is closed too late. In addition, the passenger in the area of a station must be able to concentrate entirely on the correct entry and exit. Passengers getting in and out correctly is an important aspect of safety within a chairlift station and throughout the journey from one station to another, as the manufacturer's safety measures are most effective in ensuring the proper behavior of passengers.
The invention is therefore based on the object to provide a chair and a method of the type mentioned, with which the above problems can be avoided as much as possible.
This object is achieved according to the invention with a chair of a chairlift, which has the features of claim 1.
Preferred and advantageous embodiments of the invention are the subject of the dependent claims.
Since the footrest is adjusted according to the invention of an automatic positioning mechanism and below the seat between a driving position and an entry or exit position, there is no longer any danger that a leg of a passenger is trapped, but the passenger is still not on a footrest not having to worry about closing the safety bar and positioning the footrest so that it can focus on getting in and out. In addition, the closing and opening of the safety bar and the positioning and removal of the footrest can be separated in time when entering and exiting. This means that when boarding first, the guard closed and later the footrest can be positioned and when getting off the footrest can still be moved with the guard closed. In the invention, it is particularly preferred if the footrest is movable with a vertically upward movement component before reaching the driving position. Preferably, the footrest, starting from the entry or exit position with a vertically downward movement component, which merges to the travel position in a vertically upward movement component, movable. As the footrest approaches the riding position from the underside of a ski, snowboard, or the like, when positioned in the riding position, it is prevented that the footrest can press on the top of a sports equipment.
In a preferred embodiment, a positioning mechanism and a shutter in the area of a chair lift station are arranged on the chair. In the context of the invention, the positioning mechanism may in particular be associated with a guide roller which is raised or lowered when the chair in the region of a station passes through an area with a guide device associated with the guide roller. The guide device can be, for example, a guide rail as a trigger and drive for the positioning device.
In the context of the invention, the triggering of the positioning device can also be done wirelessly. For example, a sensor may be provided as a trigger.
In a further preferred embodiment, the positioning mechanism may be connected to a mechanism for opening and closing the guard and / or for pivoting the seat. Thus, the manufacturer can easily ensure that several security measures are implemented simultaneously.
In the context of the invention, the positioning mechanism may comprise at least one motor, in particular an electric motor. In this case, the trigger in the area of a station can also be an electrical signal generator for the engine. If an electric motor is used, it can be powered by a preferably rechargeable battery which is charged outside the operating time of the chairlift and / or when passing through the chair by a station.
When the battery is to be charged while passing through a station, the battery can be connected directly to a pantograph, which is arranged on the terminal body or the hanger of each chair. When entering a cable car station of the pantograph device comes into contact with a provided in the cable car contact device, so that the battery can be charged. The current collector can have both roller contacts and sliding contacts, which interact with a correspondingly configured contact device in the station. This contact device is preferably designed as a busbar, which is arranged along the conveying cable or traction cable of the cable car system. The energy transfer can also be made contactless in the form of an inductive coupling. Here, an electric alternating field is built up by a corresponding device along the Zugsseils that is received by a corresponding device of the chair and used to charge the battery.
In a purely mechanical positioning mechanism, this can exert on the footrest, for example, by a rope a tensile force and / or for example by a linkage a compressive force. In a motor-operated positioning mechanism, ropes or linkages for exerting tensile force on the footrest need not necessarily be provided.
In one embodiment of the invention, a spring store when moving the footrest from the driving position in the entry and exit position are stretched and the footrest will be moved later from the spring storage of the entry or exit position in the drive position. As a spring memory, for example, a mechanical spring or a pressure medium cylinder can be used, which is stretched when retracting the chair in the station, while the footrest is moved from the driving position to the entry or exit position. The stored energy can then be used to move the footrest of the entry / exit position into position. On its own, this can alternatively be done in reverse by tensioning the spring accumulator out of the station when the armchair is extended and using the stored energy to move the footrest from the driving position to the entry or exit position. For tensioning the spring accumulator, the mechanism can be coupled, for example, to a guide rail in or in front of the station, as is known per se, for example, from the automatic opening and closing of the protective stirrup or protective hoods of elevators. To trigger the spring accumulator, it is then only necessary to release a lock of the spring accumulator, which can be done for example mechanically or wirelessly or electrically.
In the invention may be provided in particular that the footrest is arranged in the travel position in the area below the front edge of the seat and in the entry or exit position in the region of the trailing edge of the seat. In the context of the invention, the footrest can be arranged in the entry and exit position in the area below the seat and / or behind the backrest.
In the driving position, i. while passengers put their feet, possibly with attached skis or a snowboard, on the footrest and support, the footrest can be held by at least one tie rod in position. In embodiments of the chair according to the invention, in which the positioning mechanism remains stable enough in position, no additional struts need to be provided.
The footrest may be, for example, a crossbar which extends either at least partially across the width of a seat or substantially the entire width of the chair. In the context of the invention, differently shaped footrests, for example, plate-shaped footrests, may also be used.
Further details, features and advantages of the invention will become apparent from the following description of preferred embodiments of the invention with reference to the accompanying drawings. 1 a to 1c show a two-station chairlift system, the sequence of movements during the positioning of a footrest according to the invention during the exit from a station, FIGS. 1d and 1e the movement sequence during retraction. [0023] FIG an inventive
Footrest during entry into a station, Figs. 2 to 7 Fig. 8 and 9 Fig. 10 shows the sequence of movements in the positioning of a footrest according to the invention in detail, a detailed view of struts of the footrest according to the invention and a further embodiment of a footrest according to the invention in the position corresponding to FIG. 7.
In Fig. 1, a chairlift system with a first station 1 and a second station 2 is shown, between which chairs 3 are moved on a hoisting rope 4. The chairs can be fixed clamped or detachably connected to the hoisting rope 4.
When a passenger sits in the first station 1 on a seat 5 of a chair 3, a footrest 6 is in its entry position on the back of the chair 3 (Fig. 1a and area 1a in Fig. 1). During or shortly after the exit from the first station 1, the footrest 6 is then pivoted under the seat 5 (Fig. 1b and area 1b in Fig. 1) until it reaches the driving position shown in Fig. 1c, in which a passenger his feet or sports equipment on it. The footrest 6 then remains in this driving position until the chair 3 reaches the entrance area of the second station 2. In the entrance area of the second station 2, the footrest 6 is then pivoted back under the seat 5 (FIG. 1d and area 1d in FIG. 1) until it assumes the exit position in which the footrest 6 is again arranged on the back of the chair 3. In this exit position (Fig. 1e and area 1e in Fig. 1), the 3/16 Austrian Patent Office AT 510 521 B1 2012-12-15
Corresponds entry position, the passenger in the second station 2 can get out of the chair 3 and get a new passenger in the chair 3.
2 to 7, a chair 3 with a footrest according to the invention 6 is shown obliquely from behind. The chair 3 has four seats 5 each having a seat surface and a backrest 7, wherein the seat surface has a rear edge 8 associated with the backrest 7 and a front edge 9 lying opposite the rear edge 8. In addition, the chair 3 has a protective bar 10 which extends transversely across the seats 5 and is pivotable from an open position to a closed position.
Except for the footrest 6, the other parts may be performed as usual in the art. It is therefore only mentioned in general and by way of example that the guard 10 is arranged on a frame 11, which is connected via a hinge to a mounting bracket 12, at the upper end of a clamping device for attaching the armchair 3 is attached to the hoisting rope 4. The invention can be used for all types of armchairs.
In the embodiment shown in FIGS. 2 to 7, the footrest 6 is a transverse bar which extends substantially over the entire width of the chair 3. On the crossbar two side parts 6a, 6b are arranged, which are connected via joints 13 with parallel, pivotable rods 14, which is arranged via joints 15 on the chair 3. On the side parts 6a, 6b of the footrest 6 are struts 16, which additionally put the footrest 6 in their driving position, arranged articulated. The struts 16 may also be arranged on the pivotable rods 14 in the context of the invention. However, it is preferred that the struts 16 are arranged as close as possible to the footrest 6, since there the loads from the passengers supported on the footrest 6 can best be absorbed.
The footrest 6 and the side parts 6a, 6b form a U-shaped half-frame. In the context of the invention, the pivotable rods 14 may also be parts of a U-shaped frame with the two parallel rods and a crossbar. At this U-shaped, pivotable frame 14, the footrest 6 can be arranged as shown. Alternatively, it is possible that more than one footrest is arranged on the U-shaped, pivotable frame 14, for example in the form of a T-shaped linkage.
Per seat 5 then, for example, a footrest may be provided, extending from a crossbar of the U-shaped, pivotal frame 14 outgoing rod in driving position and seen in the direction of travel extends centrally below the seat 5. The arranged thereon footrest in the form of the T-shaped crossbar extends a maximum of the length of the front edge 9 of the seat 5. It can also be provided for every two seats a footrest, with the crossbar of the U-shaped, pivotable frame 14th outgoing rod in driving position and seen in the direction of travel between two seats 5 extends. The footrest disposed thereon then extends, for example, from the center of the one adjacent seat 5 to the middle of the other adjacent seat 5.
2, the entry or exit position of the footrest 6 is shown analogous to FIGS. 1a and 1e. In this position, in which the protective bar 10 is arranged in an open position above the seat 5, the footrest 6 and the pivotable rods 14 are located on the back of the backrest 7, wherein serving as a footrest 6 crossbar in the region of the trailing edge 8 of Seat is arranged. The planes defined by the pivotable rods 14 and by the side parts 6a, 6b and the transverse beams extend essentially parallel to the surface of the backrest 7. The struts 16 are in their initial position, in which they are substantially parallel (angle of about 10 "). a) to the side parts 6a, 6b of the footrest 6 lie.
When the chair 3 moves out of the station 1, the footrest 6 is automatically pivoted by a positioning mechanism 17 as shown in Figs. 3 to 7. The positioning mechanism 17 comprises in the illustrated embodiment according to FIG. 2 to 7 electric motors, in the region of the articulated joints 13, 15, 19 between the chair 3 and the pivoting rods 14, between the pivoting rods 14 and the side 4/16 Austrian Patent Office AT 510 521 B1 2012-12-15 6a, 6b and between the side parts 6a, 6b and the tension strut 16 are arranged. The pivoting of the footrest 6 takes place partly at the back but essentially below the seat 5.
Fig. 4 shows a position analogous to the positions shown in Figs. 1b and 1d. In the area of this position, the footrest 6 is in its lowest position and subsequently moves obliquely forwards and upwards, so that it approaches the skis or snowboards of the passengers from behind and below. The movement of the footrest 6 thus has a vertically upwardly directed and a horizontally forwardly directed movement component, before it reaches the travel position shown in FIG.
In Fig. 6, a position is shown, in which the footrest 6 is already arranged almost in the driving position. Serving as a footrest 6 crossbar is now located below the front edge 9 of the seat. In this position, the struts 16 have been pivoted from their initial position via a hinge 19 such that the free end 20 of the tension strut 16 of the front edge 9 of the seat approximates. The pivoting of the struts is effected by the electric motors 19.
In Fig. 7 the final driving position of the footrest 6 is shown analogous to Fig. 1c. In this position, serving as a footrest 6 crossbar is disposed below the front edge 9 of the seat. The struts 16 are arranged at an angle of approximately 90 ° to the side parts 6a, 6b. In this driving position, the struts 16 are in their use position, in which their free ends 20 as shown in Fig. 8 are fixed in the region of the front edge 9 of the seat to hold the footrest 6. In the driving position shown in FIG. 7, the chair 3 remains during the entire journey from the first station 1 to the inlet area of the second station 2.
8 and 9 show a arranged in the region of the front edge 9 of the seat and along its longitudinal axis movable pin 21. In driving position of the footrest 6, the pin 21 defines the free end 20 of the tie rod 16 (Fig. 8), whereas he is retracted in the position shown in Fig. 9 and the free end 20 of the tension strut 16 releases, so that the footrest 6 can be moved into the entry and exit position. Other forms of locking the struts 16 on a stable part of the chair but of course also possible.
If the free end 20 of the tension strut 16 is to be solved because the footrest 6 is to be pivoted back in the entry area of the second station 2 from the driving position to the exit position, the pin 21 is pushed into the seat 5, so that the lock the free end 20 of the tension strut 16 is released. The displacement of the pin 21 can be done in the context of the invention on the same trigger as the positioning of the footrest. 6
The pivoting of the footrest 6 from the driving position to the exit position is carried out automatically by the positioning mechanism 17 and analogous to the previous embodiments in the reverse manner.
In Fig. 10, another embodiment of a footrest according to the invention is shown in driving position. In this embodiment, the positioning mechanism 17 comprises, in addition to an electric motor arranged on the chair 3, additional cables 18 which are arranged on the pivotable rods 14, on the side parts 6a, 6b and on the struts 16. By the rope 18, a tensile force can be exerted on the said components, whereby the positioning of the footrest 6 is supported by the driving position in the entry or exit position.
The movement of the protective bow 10 can be effected in the invention at the same time or offset in time to the movement of the footrest 6. In particular, the movement of the footrest 6 from the entry or exit position into the driving position, while the movement of the footrest 6 from the driving position to the entry or exit position before the movement of the footrest 6 first carried out at a staggered movement first Opening the protective bracket 10 can be done. 5/16
