Description

Chair for chair lift

The present invention relates to a chair for a chair lift, wherein the chair has at least one seat portion pivotable about a horizontal axis.

The invention also relates to a method for pivoting at least one seat portion of a chair for a chair lift.

In order to be able to transport passengers safely, chairs for chair lifts have a safety bar. The problem with closed safety bars is that in particular large passengers may have space problems between the bottom of the closed safety bar and the seat parts. This problem cannot generally be fixed by increasing the distance between the seat part and the bottom of the closed safety bar, because too large an intermediate space greatly increases the risk of falling smaller people, especially children. Therefore, for larger passengers, an individual adaptation following the rules of force is desirable.

In EP1721801A, this is done by elastic elements in the safety bar, which press on the thighs of the passengers and allow them to move elastically in the case of a large physique. Although the risk of even small passengers slipping through it can be minimized as a result, it can cause frustration for some passengers.

The present invention is therefore based on the object of creating a device of the type mentioned at the beginning, which gives more comfort to larger passengers without reducing the safety in the process.

This object is achieved in the case of a chair of the type mentioned at the beginning in that an elastic element is arranged between the seat part and the frame of the chair and pushes the seat part upwards.

This object is also achieved by the method of the type mentioned at the beginning in that the sheet part is pivoted against the force of the resilient element.

A particular advantage of the resilient element in the device according to the invention is that the distance between the seat part and the underside of the safety bar is variable, so in the case of larger and generally also heavier people, such resilient elements are compressed and thus The space between the safety bar and the seat parts becomes larger.

In one preferred embodiment, the resilient element is pre-compressed in an unloaded position on top of the sheet part. This position is called the starting position. As a result of this argument, the vibration or shaking of the resilient element is intended to be reduced to a minimum.

In a particularly preferred embodiment of the invention, the predetermined compressive stress of the resilient element at the starting position is greater than the predetermined weight force of the passenger. If the force of the resilient element is greater than the weight of the passenger, the seat part remains in the starting position because of the resilient element. This is particularly desirable in the case of smaller passengers and children, in order not to increase the clear distance.

By means of the actuating device, the sheet part can be pivoted to a lower inlet and / or outlet position as opposed to the force of the resilient element. In this case, the seat face of the seat part forms an approximately horizontal plane at lower inlet and / or outlet positions, in particular allowing smaller passengers to get on and off more easily.

Within the scope of the present invention, provision may also be made for locking to the seat part in the inlet and / or outlet positions. Therefore, throughout the passage through the station, the seat part can be fully fixed in its comfortable lower inlet and / or outlet position.

In a particularly preferred embodiment, in order to lock the seat part in a lower position, a locking element connected to the seat part is prepared via the control element to the actuating device, in which case the locking element also connected to the seat part is a blocking element. Through the lock can be made in the inlet and / or outlet position.

In another advantageous embodiment of the invention, the blocking element is movable by the control element to the locked position and the unlocked position, in which case the locked position is the position where the seat part is locked at its lower inlet and / or outlet position. It is understood that the release position is the position at which the seat part can be pivoted.

In the unlocked position of the blocking element, the force of the resilient element automatically attempts to pivot the seat part with the passenger located within its upper or starting position and to limit the space between the underside of the safety bar and the seat part to a specified minimum. do.

The space requirements between the bottom of the closed safety bar and the seat part, which are the result of weight or height and, as a result, are generally mutually dependent variables. For example, a person weighing 90 kg generally has longer legs or larger thighs than a lighter person. In order to fit the space requirements between the underside of the safety bar and the seat parts to the length or thighs of the passenger's legs, the resilient element may be loosened after the seat parts are loosened, for example for passengers weighing less than 80 kg. The seat part is dimensioned such that it fully pivots back from the lower inlet and / or outlet position to the starting position. Therefore, the space between the bottom and seat face of the closed KEPCO bar is reduced to a set minimum value, and the risk of smaller person slipping through the safety bar and seat parts is reduced.

For example, for passengers weighing 95 kg, it is possible to assume that in order to sit comfortably they require more space between the bottom of the closed safety bar and the seat parts. In this case, the resilient element is dimensioned so as not to pivot back to the starting position after the seat part has been released. The passenger therefore has more space under the safety bar.

Thus, when the seat parts of the chair are pivotable separately, larger and relatively heavy passengers have more space than the smaller passengers sitting next to them between the bottom of the closed safety bar and the seat parts. Comfort is improved significantly, especially for larger passengers, ensuring safety for smaller and older passengers and possibly making them easier to get on and off.

Another preferred embodiment of the invention is the subject of the remaining dependent claims.

Further features and advantages of the present invention can be obtained from the following description of a preferred exemplary embodiment of the present invention with reference to the accompanying drawings.

1 is a side view of a chair of a chair lift with a first embodiment of the device according to the invention in its starting position;
2 is a side view of the appliance from FIG. 1 at the inlet and / or outlet.
3 shows a second embodiment of the device according to the invention;

1 and 2 show a resilient element 2 disposed between the pivotable seat part 4 and the frame 7 of the chair 1 around the axis 19. In addition, a pivotally mounted safety bar 8, a rear part 18, and a tiltable element 6 pivotable around the bolt 9 are mounted on or fixed to the frame 7. . The inclined element 6 is redirected via an actuating device with a drive and Bowden cable 5.

The drive (not illustrated in the figures) of the actuating device has a lever disposed on the support bar of the chair 1, for example, as known from the principle from EP1780091A. However, the type of drive of the actuating device is not limited to mechanical equipment, but may be an electric or other drive.

In FIG. 1, the seat part 4 is shown with a resilient element 2 in the upper unloaded starting position. In this case, the resilient element 2 already has a predetermined pretension at the starting position. The safety bar 8 is in the closed position. The resilient element 2 is a coil spring in the figures shown, but any other such as, for example, an annular spring, a polymer spring, a leaf spring, a disc spring, a torsion spring or a scissor spring It may be a spring of a type, referred to as spring 2 below. In the position illustrated in FIG. 1, the space between the underside of the closed safety bar 8 and the seat part 4 for passengers is limited to a defined minimum value designed for smaller and average passengers.

In FIG. 2, the seat part 4 is pivoted downwards against the force of the spring 2 by the inclined element 6, and the spring 2 is completely taut. The seat part 4 is now in the lower inlet and / or outlet position. The inclined element 6 is in this case activated via the bowden cable 5 and the drive of the actuating device.

If the use of the drive is made, for example as described in EP1780091A, the lever of the driver is actuated by the control rail at the station of the chair lift. The inclined element 6 is operated in particular in the inlet and / or outlet area of the station. Just before the exit area, the lever is actuated via the control rail and the seat part 4 is pivoted to the lower exit position. Over the time spent in the exit area, the lever abuts against the control rail. After leaving the exit area, the seat part 4 pivots back to the starting position at the end of the control rail. Just before the inlet area, the lever is actuated again via the control rail and the seat part 4 is pivoted down to the inlet position. Passing through the inlet area, it is easier for passengers to seat on the chair 1 due to the pivoted position of the seat part 4. After leaving the inlet area, the control rail also ends, and the seat part 4 can pivot up in the case of a small and average person or it can remain down in the case of a heavier person.

In a preferred embodiment, the seat part 4 can be locked in the inlet and outlet positions throughout the station by a dead center locking mechanism on the lever. Immediately after the chair 1 enters the station, the lever is operated only once and locked by the dead-point locking mechanism. Just before exiting the station, the lever is actuated again via the control rails and the loose dead-point locking mechanism. In that case, the seat part 4 is no longer locked and can pivot upwards.

In an alternative embodiment of the invention, the inclined element 6 can be eliminated, the bowden cable 5 or the connection device of the drive or the drive itself is directly connected to the seat parts 4 and the seat part Pivot (4) to the lower position. In order to hold the seat parts 4 in the lower inlet and / or outlet positions, the seat part can be locked, for example, through the drive of the actuating device, as described above.

3 shows another further developed embodiment of the invention, in which the control element 4 is connected to the inclined element 6 and thereby actuated. The control element 14 has an opening 13 with a control slot through which the bolt 12 of the locking element 10 is received, which lock element 10 is firmly connected to the seat part 4. The control element 14 is moved in the direction of the double arrow 21 by the tilting element 6. As a result, the seat part 4 can be pivoted against the force of the spring 2 via the locking element 10 connected to the control element 14 via the opening and bolt 12.

The actuating device may consist of the same components as described above.

In order to pivot the seat part 4 against the spring 2 with the embodiment according to the invention in FIG. 3, the bowden cable 5 and the inclined element 6, as described in FIGS. 1 and 2. It is essential that a force be applied to the control element 14 via. The control element 14 in this case moves to the right in the direction of the arrow 21 with the bolt 12 against the left end of the opening 13. In this case, the control element 14 moves to the maximum to the extent that the spring 2 is tightened to the maximum value, and the blocking element 11 loaded counterclockwise by the spring has a recessed portion (1) in the locking element 10. The latch in place of 16) has been latched and locks the seat part 4 in the lower inlet and / or outlet positions as illustrated in FIG.

In addition to the opening 13, the control element 14 has a defined control cam 15 through which the blocking element 11 is held and guided by spring force. By means of the control cam 15, the blocking element 11 located in the locked position is redirected from the recess 16 in the locking element 10 and thus the seat part 4 is released. For this purpose, the control element 14 must be moved to the left in the direction of the arrow 21 via the bowden cable 5 and the inclined element. In this case, the defined control cam 15 is formed such that the blocking element 11 which abuts against the control element 14 is moved out of the recess 16. In this case the bolt 12 is unloaded and positioned between the two ends of the opening 13 or its control slot so that the seat part 4 can move up through the force of the spring 2.

In another development of the embodiment in FIG. 3, if the control element 14 continues to move to the left in the direction of the arrow 21, the seat part 4 abuts against the rear part 18 and pivots upwards to the right. Can be. This embodiment according to the invention therefore allows the seat part 4 to pivot from the lower inlet and / or outlet position to the starting position, and if necessary also the seat part 4 fits the rear part 18. Allows it to touch or pivot to the highest position pivoted up at least near the rear part 18. In order to lock the seat part 4 in the highest position, an additional recess (not illustrated) on which the blocking element 11 latches is located on the locking element 10. In order to unlock the seat part 4 from the uppermost position in which it has been locked, the blocking element 11 is redirected from the recess by the control element 14 as described above. To this end, in this embodiment the control element 14 has an extension of the control cam 15 in order to change the direction of the blocking element 11 from the lock.

In all the embodiments of FIG. 3, the opening 13 is bolted to a length that allows at least the seat part 4 to pivot from the starting position to the lower inlet and / or outlet position when a heavy person is seated on the seat. It should be long enough to add the diameter of 12).

In the embodiment of FIG. 3, when entering the station, the lever (not illustrated) of the device is pivoted down the right side with the locking element 10 by means of a control rail, and on the blocking element 11. The direction should be changed only once so that the locking is achieved. Immediately before exiting the station, the lever is actuated again via the control rail and pivots from the recess 16 such that the direction of the blocking element 11 is changed by the control element 14 so that the seat part 4 is released again. do.

The use of the blocking element 11 to lock the seat part 4 in the inlet and / or outlet position is also not necessary in the embodiment in FIG. 3. Alternatively, some other electrical, pneumatic, hydraulic or mechanical appliance can also be used to lock the seat part 4.

The mechanical reversal between the locking element 10 and the control element 14 is such that a bolt 12, which is fixed to the locking element 10, is located on the control element 14 and at the opening in the locking element 10. Of course, as long as the mesh is interlocked.
