Description
2~3~ 32~
The invention concprn~ a chair for a chair lift comprising a suspension bar and a pivotable ~aU~e~ protection cover carried U~ y, wherein movably mounted to the sll~p~n~ion bar above the weather protection cover is an actuating device which is movable by a S control device specific to the station and the movement of which is LL~ ~tted by way of a Ll~,.~ni~sion means to the pivotal movement of the weather protection cover, and a locking device for locking the closed weather protection cover. The invention further conc~rn~ a cable car for a cable car lift ccmprising a suspension bar and a cabin carried by the sll~pPn~ion bar, with an autcmatically actuable door, wherein mounted movably on the suspension bar above the cabin is an actuating device which is movable by a control device associated with the station and the movement of which is LL~ itted by way of a L~ sion means to the closing and opening Inuv~l~nt of the door, and a locking device for locking the closed door.
In relation to chairs with pivotable weather protection covers or hoods ('cover-type chairs'), it is usual for at least the unocc ~i~ chairs to be autcmatically closed when leaving the station.
The actuating m~h~ni~m which is provided for that purpose, being associated with the chair, may for ~x~.~le ccmprise a lever which is pivotably ~ unted to the suspension assembly and which carries a control roller at its free end. When moving out of the station, th~t conLlol roller passes on to an actuating device which is specific to the station, in the simplest case on to a closing rail which is arranged in a slightly ;n~l ine~ position relative to the direction of travel and which pivots the actuating lever. That pivotal movement of the actuating lever can then be transferred to a closing movement of the weather protection cover by way of a linkage, a Bowden cable or other l~ "~i~sinn means. It has now been found that, under the effect of wind, it repeatedly h~ppPn~ that the weather protection covers are automatically opened by the force of the wind. me opened covers now afford a larger area for the wind to act Ulel~on, whereby the chairs may suffer from undesirably severe swinging or oscillating ~ ~l~nts.
In addition that means that the seat area is freely exposed to the influ~nces of the weather and therefore the arrangement can be adversely affected by snow and ice overnight, which is undesirable.
It is already known for the weather protection covers to be locked in the closed position by pins which have to be inserted by hand. mat however requires a greater degree of operator involvement and, before the covers are opened, it is n~cPss~ry to ensure that the pin has been removed in order to avoid damage to the actuating mech~ni~m.
In addition, it is known from European patent specification No 0 242 242 Bl for the weather protection covers to be closed by a lock member which directly engages the weather protection covers and which is closed by way of a separate control rail when leaving the station and opened by way of a Se~aL~ Le control rail when passing into the station. A disadvantage of that proposal lies in the need for separate control rails for the lock II~ILeL~ which not only represent an increase in structure but also, by virtue of being arranged in the region of the point of entry and exit, also have an adverse effect on passengers entering and leaving the chair. A further disadvantage of the known proposal is that the lock l,~l~eL is n~cP~s~rily also locked on chairs which are occupied by passengers. The passenger therefore does not have any option of opening the weather protection cover.
Particularly in the event of disturbances in the operational procedure, because of the relatively small amount of space beneath the weather protection cover, the lack of any option of opening the cover can result in panic-type situations occurring.
The object of the present invention is that of providing a chair or cable car of the kind set forth in the opening part of this specification, wherein automatic locking is possible after closure of the weather protection cover of the chair or the door of the cable car, without additional control rails for the locking function being necessary for that purpose. The invention further seeks to provide that the locking device according to the invention can be easily subsequently installed without alteration to the chair covers or cable car doors and without changing the actuating devices specific to the station (closing and opening rails for the chair covers or cable car doors).
The invention provides a chair for a chair lift comprising a suspension bar and a pivotable weather protection cover carried thereby, wherein movably mounted to the suspension bar above the weather protection cover is an actuating device which is movable by a control device associated with a lift station and movement of which is transmitted by way of a transmission means to effect pivotal ~ove~.cnt of the weather protection cover; and a locking device for locking the weather protection cover in closed condition, characterised in that the locking device is arranged on the actuating device above the weather protection cover, said locking device operating to lock the actuating device with respect to the suspension bar or a member connected thereto.
The invention also provides a cable car for a cable car lift comprising a suspension bar and a cabin carried by the suspension bar, with an automatically actuable door, wherein mounted movably on the suspension bar above the cabin is an actuating device which is movable by a control device associated with a lift station and l"oval"a-lt of which is transmitted by way of a transmission means to closing and opening ~,o-vt~.ellt of the door, and a locking device for locking door closed characterised in that the locking device is A~
arranged on the actuating device above the cabin, said locking device operating to lock the actuating device with respect to the suspension bar or a member connected thereto.
Although the locking device according to the invention is also suitable for doors of cable cars, reference is primarily made hereinafter to chairs, with similar considerations which the man skilled in the art can readily appreciate generally applying to cable car lifts. Hereinafter the term suspension means denotes a chair of a chair lift or a car of a cable car lift.
In contrast to the arrangement disclosed in European patent specification No. 0 242 242 B1, the locking device according to the invention does not engage the chair cover but directly engages the actuating device specific to the chair, which is mounted above the weather protection cover on the suspension bar. That permits the locking device to be actuated by way of the station-associated control devices, which are present in any case, for opening and closing the ~.,, 2 ~ 2 &
weather protection covers (opening and closing rails), without the need for that purpose for additional control rails for the locking device, which rails cause problems in the entry and exit region.
Without additional devices therefore that arrangement can provide for direct and functi~nAlly r~liAhl~ locking of the actuating device on the suspension h-ar and thus locking of the weather protection cover.
The locking device according to the invention is arranged in the upper region of the suspension bar, at a position which is advantageous in terms of space, and can also he subsequently installed on existing chairs without mcdifying the chair covers and without changing the closing and opening rail~.
In the case of a suspension means in which the actuating device has an actuating lever which is pivotably mounted to the suspension bar and the pivotal movement of which is L~ ~tted by way of a LL~"~"i~ision means in the form of a linkage, Bawden cable or the like, it is preferably provided that a second lever in the form of a latching pawl is mounted on that actuating lever pivotably in an An~llAr range which is restricted by abutments with respect to the actuating lever, wherein the latching pawl for locking the actuating lever in the position of the closed weather protection cover or door latches into a co-operating latch means connected to the suspension bar. The latching pawl may engage into a co-operating latch means connected to the susp~n~ n bar for locking the actuating lever and Ule~ the weather protection cover, the latching pawl being actuable directly by station - associated control devices (opening rails, closing rail~).
The m~de of operation of the double pivot lever comprising the actuating lever and the latching pawl is now as follaws: when an unocc~ chair moves out of the station, an actuating roller which is preferably provided on the latching pawl runs on to a closing rail which is slightly in~linetl relative to the direction of conveying ~1)63~2~
movement and in doing so initially pivots only the latching pawl. The latching pawl thereupon engages a first abutment on the actuating lever and entrains same in the further pivotal movement which is caused by the closing rail. When that happens, the weather protection cover closes. At the end of the closing ~ vement, the latching pawl now engages into a co-operating latch means on the suspen~i~n bar.
For ~x~m~le the latching pawl may have a latching projection which engages behind a co-operating latch means which is in the form of a pin. In that way the weather protection cover of the chair which is moving out of the station is closed and locked so that there cannot be any undesired opening thereof due to the inflll~nc~s of wind as the chair moves along. When the chair moves into the opposite station, the latching pawl initially performs a pivotal movement, due to the effect of an opening rail, with the latch m g pawl coming out of engagement with the co-operating latch means. After a given pivotal movement of the latching pawl, it engages a second abutment on the actuating lever and entrains same, thereby causing the weather protection cover to open.
The chairs which are fitted with the locking device according to the invention can readily remain out on the cable overnight. For that purpose, the chair lift only needs to be moved by half a total circuit with the closing rail in the top and bottom stations in the closed position. In that situation, the weather protection covers of the unoccupied chairs automatically close and lock when leaving the station and are. thus best protected from the influences of wind and weather. When the system is brought back into operation again, there is no need to take any particular precautions as, when the weather protection covers open, when passing into the station, unlocking automatically occurs beforehand.
In order to permit the passenger to leave the weather protection cover open, for ~x~mpl~ in fine weather, and so that the passengers are not put at risk when an occupied chair moves out of a 2 13 ~ S ~
station, it is already known for the closing rail at the station exit to be moved into a neutral position in which the actuating mP~h~ni~m associated with the chair for closing the weather protection cover is not actuated. In the case of a closing rail, that neutral position can be easily attained for ~m~le by the rail being pivoted away into a position in which it is parallel to the direction of conveying movement. Therefore, when chairs are occupied, the weather protection cover is preferably not necessarily closed. If the passenger ~ci~es to close the weather protection cover, he can easily do that by hand.
In that case however the weather protection cover is ~l~feldbly not locked in the closed position by the locking device. That means that the passenger has the option at any time of opening the weather protection cover, which is advantageous in par~ r in the event of trouble. With the above-mentioned double pivot lever comprising the actuating lever and the latching pawl, that 'non-locking effect' occurs automatic~lly upon muml~l closure: more specifically, upon manll~l closure, the latching pawl remains be ~ ing against the above-mentioned second abutment on the actuating lever and does not change in its relative position with respect to the actuating lever. In that way, although upon nRnu~l closure the actuating lever pivots together with the latching pawl mounted thereon, in that position the latching pawl does not engage behind the co-operating latch means, whereby it is also again possible for the cover to be easily opened by the passenger.
It should also be mentioned that detection of whether a chair is or is not occupied can be effected in known manner by a known light barrier ~ r~n~m~nt which detects the leg region of the passenger, the position of the closing rail being v ~ iable in ~L~ nce on the light barrier arrangement signal.
Further advantages and details of the invention will be described in greater detail with reference to the specific description hereinafter.

Figure 1 is a diay~ ic side view of a cover-type chair in accordance with the state of the art and statior, - associatecl control devices (opening and closing rails) for automatically opening and closing the weather pnotection cover, Figure 2 shows an embodiment of a chair according to the invention and in particular the locking device according to the invention, in a diayl~ aLic side view, illustrating a plurality of positions of the chair - associated actuating device and the locking device, Figure 3 is a diayl~l.,~Lic side view of a further embcdiment of the actuating device according to the invention with locking device, Figure 4 is a diayL~l~Lic plan view of the arrangement shown in Figure 3, and Figure 5 is a side view of a car of a cable car lift, fitted with a locking device according to the invention.
Figure 1 shows a chair 1 in accon~ance with the state of the art, which is clamped fast by way of a clamp 2 to the conveyor cable 4 which is moved in the direction of conveying movement as indicated at 3. m e chair 1 has a weather protection cover of Ll~ls~dLellt plastic material which is closed in the position shcwn in Figure 1.
The weather protection cover can be pivoted open about the pivot mounting 6 in the direction indicated by the arrow 7 in order to penmit the passengers to climb in and out. Opening and closing of the weather protection cover 5 when the chair moves into and out of the station can occur automatically. For that purpose, there is pr,ovided an actuating device 11 which is specific to tpe chair and which in the present case essential1y comprises an actuating lever 11. The actuating lever 11 is mounted to the suspPn~ion bar 9 pivotably about an axis 10 and has an actuating roller 12 at its free end. A linkage 8a, 8b which acts as a tr~n~mi~sion means transmits the movement of the actuating lever 11 to a pivotal movement of the weather 2 0 6 ~ ~ 2 &
protection cover. m e actuating roller 12 runs on to control devices which are specific to the station, when the chair moves in the station. me station-specific control device for opening the weather protection cover 5 is an opening rail 13 which is arranged incl;ne~ly S relative to the direction of movement 3 and which pivots the actuating lever 11. m at pivotal movement is then converted by way of the linkage 8a, 8b into an opening movement of the weather protection cover 5. When the weather protection cover is in the open position, the actuating lever is in the position shown in broken line in Figure 1. me station-specific control device for closing the weather protection cover when the chair leaves the station is a similar closing rail 14. The moving chair supplies the nPc~ss~ry energy for the opening and closing movements.
me opening and closing rails 13 and 14 respectively can be pivoted into a neutral position in which they are disposed parallel to the direction of conveying movement and do not come into contact with the actuating roller. That is desired in particular when occupied chairs leave the station. If a light barrier arrangement detects that the chair is occupied, the closing rail 14 moves into the neutral position and the weather protection cover is not necessarily closed. Gn the contrary the passenger can himself decide whether he does or does not wish to close the weather protection cover. Unoccupied chairs are automatically closed on leaving the station by way of the closing rail 14, the actuating lever 11 and the linkage 8a, 8b.
Hitherto the problem arose that the weather protection covers were opened by the influences of wind when the chairs were out on the cable, thus resulting in a large area for the wind to act upon and giving rise accordingly to undesired severe swinging or oscillation movement of the chair. In addition, when the weather protection cover is in an open condition, the seat surface is fully exposed to the influences of the weather (snow and ice).
2 3 ~
In order to avoid that and in order for the weather protection cover of the unoccupied chair to be securely held closed out on the cable, in the embodiment shown in Figure 2, in accordance with a preferred ~mhc~i~ent of the invention, there is provided a latching pawl 16 which is mounted pivotably on the actuating lever 11 (pivot axis 15) and which, in the locked position shown in solid lines, engages with a locking projection 16a behind a co-operating latch means 17 which is fixed with respect to the suspension means and which can be for Px~m~le in the fonm of a pin.
The mode of operation of the double pivot lever shown in Figure 2, which comprises the actuating lever 11 and the latching pawl 16, is as follows: in the open position of the weather protection cover 5, the double pivot lever is in the position shown in broken line and identified by L~LeLence numeral 18a. Instead of the previous arrangement of the actuating roller 12 directly on the actuating lever 11 (Figure 1), the actuating roller 12' is now disposed on a projection 19 of the latching pawl 16. There is therefore still only a single actuating roller 12'. When now the actuating roller 12' runs on to the closing rail 14, the latching pawl 16 is initially pivoted by the control rail relative to the actuating lever 11 until the latching pawl 16 bears against the abutment a on the actuating lever 11 (position 18b). From that moment, the latching pawl 16 which is pressed up by the closing rail 14 entrains the actuating lever 11, with the weather protection cover 5 being closed. At the end of the closing movement the latching projection 16a automatically engages behind the co-operating latch means 17 so that the actuating lever 11 is locked. The weather protection cover 5 is th~L~LoL~ not only closed but at the same time also locked to prevent it from being undesirably opened by wind.
In the opposite station the actuating roller 12' runs on to an opening rail 13, whereby firstly the latching pawl 16 of the double 2~6~ ~2~
pivot lever is pivoted relative to the actuating lever 11 into the position shown in broken line and identified by reference numeral 18c. In that position a portion of the latching pawl 16 bears against the abutment b of the actuating lever 11. Frcm that position the latching pawl 16 entrains the actuating lever 11 and the weather protection cover is opened, until the double pivot lever is in the position identified by reference numeral 18a.
The locking device according to the invention can be easily subsequently fitted to existing chair lifts, with no modifications being required at the stations. On the contrary the locking device, in accordance with a particular feature of the invention, is automatically actuated by the opening and closing rails which are already present in any case for the weather protection cover. The arrangement provides for operation~lly r~ hl~ locking of the actuating lever on the suspension bar.
When an occupied chair leaves the station, it is deemed desirable for the weather protection ccver not to be necessarily closed. That does not endanger the passengers and the passenger can intentio~lly leave the weather protection cover open. For that purpose the closing rail 14 only needs to be pivoted out of the region of the actuating roller 12'. If now the passenger closes the weather protection cover while the chair is on the cable between the stations, the actuating lever 11 pivots into the position shown in solid lines in Figure 2, without that involving a change in the relative position of the latching pawl 16 with respect to the actuating lever 11. In the ~Rnll~lly closed position thel~LoL~ the latching pawl 16 is in the position which is identified by reference numeral 18c and in which it does not engage behind the co-operating latch means 17. Therefore, there is intentionally no locking effect when the weather protection cover is closed m~nll~lly, in order to permit the passenger to open the weather protection cover at any time.
Figures 3 and 4 show a further embodiment of the double pivot lever according to the invention, the same reference numerals identifying the same or equivalent components as in Figure 2. In the embcdiment shown in Figures 3 and 4, the actuating lever 11 which is of a cranked configuration is mounted on the holder 21 pivotably about a pivot axis 20. me diayL~",~Lically indicated spring 22 is not essential in regard to the mode of operation of the arrangement and only serves in a fault situation to prevent ; n~mi ~sible pivotal movement of the actuating lever into the clear space profile which is to be kept free. The second part of the double pivot lever, namely the latching pawl 16, is shown in solid lines in Figure 3 in the position in which it is locked to the co-operating latch means 17.
The abutments which are required for operation of the arrangement and which restrict the relative pivotal movement of the latching pawl 16 with respect to the actuating lever 11 are provided in the embodiment shown in Figures 3 and 4 by the actuating lever 11 having a slot 23 in which a pin 24 which is fixedly connected to the latching pawl 16 is movable. The two ends of the slot 23 form the abu~l~nLs for restricting the pivotal movement as between the latching pawl and the actuating lever.
The embodiment shown in Figures 3 and 4 also has as a further particularity a movable co-operating latch means 17 which is spring-loaded towards the latching pawl 16. In that arrangement the co-operating latch means 17 is in the form of a pin projecting from a pivotable lever 25 wnichis spring-loaded by a spring 26 in the direction indicated by the arrow 27, that is to say towards the latching projection 16a. An abutment (not shown) restricts the pivotal movement of the lever 25 in the direction of the arrow 27 when the latching pawl 16 is disengaged. The resilient mounting of the co-operating latch means 17 has the advantage that engagement of the latching pawl which is absolutely satisfactory from the functional point of view is possible. When the latching pawl pivots 2~
apen, the spring-loaded co-operating latch means can firstly ~ ve back from the outside of the latching projection 16a into the position shown in broken lines in Figure 3, against the spring loading. When the latching pawl 16 reaches the end position, the co-operating latch means 17 automatically comes into ~n~rping engagementunder the latching pawl, thus producing the locking action.
Finally, the embodiment shown in Figures 3 and 4 also has the feature that the pivotal connection between the actuating lever 11 and the latching pawl 16 is intentinn~lly made difficult to move in order to prevent unintentional relative pivotal movement as between the latching pawl 16 and the actuating lever 11, other than upon actuation by the opening or closing rail. That difficulty of movement in relation to the above-indicated connection can be achieved for ~x~mrl~ by the two lever portions 11 and 16 being resiliently pressed against each other so that the friction between them is increased. In the ~mhc~impnt shown in Figures 3 and 4, a spring 29 is provided for that purpose, which spring can be ~lesLlessed by way of a nut 28.
As already mentioned in the opening part of this specification, the locking device according to the invention is suitable in parti~l1Ar for cover-type chairs, that is to say chairs with weather protection covers.
In principle however it is also conceivable and possible for such a locking device to be used to advantage in relation to cable ~r l;fts. The embodiment shown in Figure 5 ill~sLldLes a conrlp~hle cable car 30, the door 31 of which can be automatically apened or closed in the stations. Such opening is effected by way of an actuating device which is associated with the cable car and a tr~ncmi~sion means of which only the upper region is illusLlaLed. The Ll~ si nn means as such, that is to say the Ll~ ",i~sion of the pivotal movement of the actuating lever 11 to an opening or closing movement of the door, is well-known to the man skilled in the art and -2 ~
therefore does not need to be described in detail herein. Once again the arrangement has the double pivot lever ccmprising the actuating lever 11 and the latching pawl 16, by way of which locking of the doors is possible automatically when the doors close. The mode of operation of the double pivot lever shown in Figure 5 is the same as that of the double pivot lever shown in Figure 2.
The invention concprn~ a chair for a chair lift comprising a suspension bar and a pivotable ~aU~e~ protection cover carried U~ y, wherein movably mounted to the sll~p~n~ion bar above the weather protection cover is an actuating device which is movable by a S control device specific to the station and the movement of which is LL~ ~tted by way of a Ll~,.~ni~sion means to the pivotal movement of the weather protection cover, and a locking device for locking the closed weather protection cover. The invention further conc~rn~ a cable car for a cable car lift ccmprising a suspension bar and a cabin carried by the sll~pPn~ion bar, with an autcmatically actuable door, wherein mounted movably on the suspension bar above the cabin is an actuating device which is movable by a control device associated with the station and the movement of which is LL~ itted by way of a L~ sion means to the closing and opening Inuv~l~nt of the door, and a locking device for locking the closed door.
In relation to chairs with pivotable weather protection covers or hoods ('cover-type chairs'), it is usual for at least the unocc ~i~ chairs to be autcmatically closed when leaving the station.
The actuating m~h~ni~m which is provided for that purpose, being associated with the chair, may for ~x~.~le ccmprise a lever which is pivotably ~ unted to the suspension assembly and which carries a control roller at its free end. When moving out of the station, th~t conLlol roller passes on to an actuating device which is specific to the station, in the simplest case on to a closing rail which is arranged in a slightly ;n~l ine~ position relative to the direction of travel and which pivots the actuating lever. That pivotal movement of the actuating lever can then be transferred to a closing movement of the weather protection cover by way of a linkage, a Bowden cable or other l~ "~i~sinn means. It has now been found that, under the effect of wind, it repeatedly h~ppPn~ that the weather protection covers are automatically opened by the force of the wind. me opened covers now afford a larger area for the wind to act Ulel~on, whereby the chairs may suffer from undesirably severe swinging or oscillating ~ ~l~nts.
In addition that means that the seat area is freely exposed to the influ~nces of the weather and therefore the arrangement can be adversely affected by snow and ice overnight, which is undesirable.
It is already known for the weather protection covers to be locked in the closed position by pins which have to be inserted by hand. mat however requires a greater degree of operator involvement and, before the covers are opened, it is n~cPss~ry to ensure that the pin has been removed in order to avoid damage to the actuating mech~ni~m.
In addition, it is known from European patent specification No 0 242 242 Bl for the weather protection covers to be closed by a lock member which directly engages the weather protection covers and which is closed by way of a separate control rail when leaving the station and opened by way of a Se~aL~ Le control rail when passing into the station. A disadvantage of that proposal lies in the need for separate control rails for the lock II~ILeL~ which not only represent an increase in structure but also, by virtue of being arranged in the region of the point of entry and exit, also have an adverse effect on passengers entering and leaving the chair. A further disadvantage of the known proposal is that the lock l,~l~eL is n~cP~s~rily also locked on chairs which are occupied by passengers. The passenger therefore does not have any option of opening the weather protection cover.
Particularly in the event of disturbances in the operational procedure, because of the relatively small amount of space beneath the weather protection cover, the lack of any option of opening the cover can result in panic-type situations occurring.
The object of the present invention is that of providing a chair or cable car of the kind set forth in the opening part of this specification, wherein automatic locking is possible after closure of the weather protection cover of the chair or the door of the cable car, without additional control rails for the locking function being necessary for that purpose. The invention further seeks to provide that the locking device according to the invention can be easily subsequently installed without alteration to the chair covers or cable car doors and without changing the actuating devices specific to the station (closing and opening rails for the chair covers or cable car doors).
The invention provides a chair for a chair lift comprising a suspension bar and a pivotable weather protection cover carried thereby, wherein movably mounted to the suspension bar above the weather protection cover is an actuating device which is movable by a control device associated with a lift station and movement of which is transmitted by way of a transmission means to effect pivotal ~ove~.cnt of the weather protection cover; and a locking device for locking the weather protection cover in closed condition, characterised in that the locking device is arranged on the actuating device above the weather protection cover, said locking device operating to lock the actuating device with respect to the suspension bar or a member connected thereto.
The invention also provides a cable car for a cable car lift comprising a suspension bar and a cabin carried by the suspension bar, with an automatically actuable door, wherein mounted movably on the suspension bar above the cabin is an actuating device which is movable by a control device associated with a lift station and l"oval"a-lt of which is transmitted by way of a transmission means to closing and opening ~,o-vt~.ellt of the door, and a locking device for locking door closed characterised in that the locking device is A~
arranged on the actuating device above the cabin, said locking device operating to lock the actuating device with respect to the suspension bar or a member connected thereto.
Although the locking device according to the invention is also suitable for doors of cable cars, reference is primarily made hereinafter to chairs, with similar considerations which the man skilled in the art can readily appreciate generally applying to cable car lifts. Hereinafter the term suspension means denotes a chair of a chair lift or a car of a cable car lift.
In contrast to the arrangement disclosed in European patent specification No. 0 242 242 B1, the locking device according to the invention does not engage the chair cover but directly engages the actuating device specific to the chair, which is mounted above the weather protection cover on the suspension bar. That permits the locking device to be actuated by way of the station-associated control devices, which are present in any case, for opening and closing the ~.,, 2 ~ 2 &
weather protection covers (opening and closing rails), without the need for that purpose for additional control rails for the locking device, which rails cause problems in the entry and exit region.
Without additional devices therefore that arrangement can provide for direct and functi~nAlly r~liAhl~ locking of the actuating device on the suspension h-ar and thus locking of the weather protection cover.
The locking device according to the invention is arranged in the upper region of the suspension bar, at a position which is advantageous in terms of space, and can also he subsequently installed on existing chairs without mcdifying the chair covers and without changing the closing and opening rail~.
In the case of a suspension means in which the actuating device has an actuating lever which is pivotably mounted to the suspension bar and the pivotal movement of which is L~ ~tted by way of a LL~"~"i~ision means in the form of a linkage, Bawden cable or the like, it is preferably provided that a second lever in the form of a latching pawl is mounted on that actuating lever pivotably in an An~llAr range which is restricted by abutments with respect to the actuating lever, wherein the latching pawl for locking the actuating lever in the position of the closed weather protection cover or door latches into a co-operating latch means connected to the suspension bar. The latching pawl may engage into a co-operating latch means connected to the susp~n~ n bar for locking the actuating lever and Ule~ the weather protection cover, the latching pawl being actuable directly by station - associated control devices (opening rails, closing rail~).
The m~de of operation of the double pivot lever comprising the actuating lever and the latching pawl is now as follaws: when an unocc~ chair moves out of the station, an actuating roller which is preferably provided on the latching pawl runs on to a closing rail which is slightly in~linetl relative to the direction of conveying ~1)63~2~
movement and in doing so initially pivots only the latching pawl. The latching pawl thereupon engages a first abutment on the actuating lever and entrains same in the further pivotal movement which is caused by the closing rail. When that happens, the weather protection cover closes. At the end of the closing ~ vement, the latching pawl now engages into a co-operating latch means on the suspen~i~n bar.
For ~x~m~le the latching pawl may have a latching projection which engages behind a co-operating latch means which is in the form of a pin. In that way the weather protection cover of the chair which is moving out of the station is closed and locked so that there cannot be any undesired opening thereof due to the inflll~nc~s of wind as the chair moves along. When the chair moves into the opposite station, the latching pawl initially performs a pivotal movement, due to the effect of an opening rail, with the latch m g pawl coming out of engagement with the co-operating latch means. After a given pivotal movement of the latching pawl, it engages a second abutment on the actuating lever and entrains same, thereby causing the weather protection cover to open.
The chairs which are fitted with the locking device according to the invention can readily remain out on the cable overnight. For that purpose, the chair lift only needs to be moved by half a total circuit with the closing rail in the top and bottom stations in the closed position. In that situation, the weather protection covers of the unoccupied chairs automatically close and lock when leaving the station and are. thus best protected from the influences of wind and weather. When the system is brought back into operation again, there is no need to take any particular precautions as, when the weather protection covers open, when passing into the station, unlocking automatically occurs beforehand.
In order to permit the passenger to leave the weather protection cover open, for ~x~mpl~ in fine weather, and so that the passengers are not put at risk when an occupied chair moves out of a 2 13 ~ S ~
station, it is already known for the closing rail at the station exit to be moved into a neutral position in which the actuating mP~h~ni~m associated with the chair for closing the weather protection cover is not actuated. In the case of a closing rail, that neutral position can be easily attained for ~m~le by the rail being pivoted away into a position in which it is parallel to the direction of conveying movement. Therefore, when chairs are occupied, the weather protection cover is preferably not necessarily closed. If the passenger ~ci~es to close the weather protection cover, he can easily do that by hand.
In that case however the weather protection cover is ~l~feldbly not locked in the closed position by the locking device. That means that the passenger has the option at any time of opening the weather protection cover, which is advantageous in par~ r in the event of trouble. With the above-mentioned double pivot lever comprising the actuating lever and the latching pawl, that 'non-locking effect' occurs automatic~lly upon muml~l closure: more specifically, upon manll~l closure, the latching pawl remains be ~ ing against the above-mentioned second abutment on the actuating lever and does not change in its relative position with respect to the actuating lever. In that way, although upon nRnu~l closure the actuating lever pivots together with the latching pawl mounted thereon, in that position the latching pawl does not engage behind the co-operating latch means, whereby it is also again possible for the cover to be easily opened by the passenger.
It should also be mentioned that detection of whether a chair is or is not occupied can be effected in known manner by a known light barrier ~ r~n~m~nt which detects the leg region of the passenger, the position of the closing rail being v ~ iable in ~L~ nce on the light barrier arrangement signal.
Further advantages and details of the invention will be described in greater detail with reference to the specific description hereinafter.
~Q~5~2~
Figure 1 is a diay~ ic side view of a cover-type chair in accordance with the state of the art and statior, - associatecl control devices (opening and closing rails) for automatically opening and closing the weather pnotection cover, Figure 2 shows an embodiment of a chair according to the invention and in particular the locking device according to the invention, in a diayl~ aLic side view, illustrating a plurality of positions of the chair - associated actuating device and the locking device, Figure 3 is a diayl~l.,~Lic side view of a further embcdiment of the actuating device according to the invention with locking device, Figure 4 is a diayL~l~Lic plan view of the arrangement shown in Figure 3, and Figure 5 is a side view of a car of a cable car lift, fitted with a locking device according to the invention.
Figure 1 shows a chair 1 in accon~ance with the state of the art, which is clamped fast by way of a clamp 2 to the conveyor cable 4 which is moved in the direction of conveying movement as indicated at 3. m e chair 1 has a weather protection cover of Ll~ls~dLellt plastic material which is closed in the position shcwn in Figure 1.
The weather protection cover can be pivoted open about the pivot mounting 6 in the direction indicated by the arrow 7 in order to penmit the passengers to climb in and out. Opening and closing of the weather protection cover 5 when the chair moves into and out of the station can occur automatically. For that purpose, there is pr,ovided an actuating device 11 which is specific to tpe chair and which in the present case essential1y comprises an actuating lever 11. The actuating lever 11 is mounted to the suspPn~ion bar 9 pivotably about an axis 10 and has an actuating roller 12 at its free end. A linkage 8a, 8b which acts as a tr~n~mi~sion means transmits the movement of the actuating lever 11 to a pivotal movement of the weather 2 0 6 ~ ~ 2 &
protection cover. m e actuating roller 12 runs on to control devices which are specific to the station, when the chair moves in the station. me station-specific control device for opening the weather protection cover 5 is an opening rail 13 which is arranged incl;ne~ly S relative to the direction of movement 3 and which pivots the actuating lever 11. m at pivotal movement is then converted by way of the linkage 8a, 8b into an opening movement of the weather protection cover 5. When the weather protection cover is in the open position, the actuating lever is in the position shown in broken line in Figure 1. me station-specific control device for closing the weather protection cover when the chair leaves the station is a similar closing rail 14. The moving chair supplies the nPc~ss~ry energy for the opening and closing movements.
me opening and closing rails 13 and 14 respectively can be pivoted into a neutral position in which they are disposed parallel to the direction of conveying movement and do not come into contact with the actuating roller. That is desired in particular when occupied chairs leave the station. If a light barrier arrangement detects that the chair is occupied, the closing rail 14 moves into the neutral position and the weather protection cover is not necessarily closed. Gn the contrary the passenger can himself decide whether he does or does not wish to close the weather protection cover. Unoccupied chairs are automatically closed on leaving the station by way of the closing rail 14, the actuating lever 11 and the linkage 8a, 8b.
Hitherto the problem arose that the weather protection covers were opened by the influences of wind when the chairs were out on the cable, thus resulting in a large area for the wind to act upon and giving rise accordingly to undesired severe swinging or oscillation movement of the chair. In addition, when the weather protection cover is in an open condition, the seat surface is fully exposed to the influences of the weather (snow and ice).
2 3 ~
In order to avoid that and in order for the weather protection cover of the unoccupied chair to be securely held closed out on the cable, in the embodiment shown in Figure 2, in accordance with a preferred ~mhc~i~ent of the invention, there is provided a latching pawl 16 which is mounted pivotably on the actuating lever 11 (pivot axis 15) and which, in the locked position shown in solid lines, engages with a locking projection 16a behind a co-operating latch means 17 which is fixed with respect to the suspension means and which can be for Px~m~le in the fonm of a pin.
The mode of operation of the double pivot lever shown in Figure 2, which comprises the actuating lever 11 and the latching pawl 16, is as follows: in the open position of the weather protection cover 5, the double pivot lever is in the position shown in broken line and identified by L~LeLence numeral 18a. Instead of the previous arrangement of the actuating roller 12 directly on the actuating lever 11 (Figure 1), the actuating roller 12' is now disposed on a projection 19 of the latching pawl 16. There is therefore still only a single actuating roller 12'. When now the actuating roller 12' runs on to the closing rail 14, the latching pawl 16 is initially pivoted by the control rail relative to the actuating lever 11 until the latching pawl 16 bears against the abutment a on the actuating lever 11 (position 18b). From that moment, the latching pawl 16 which is pressed up by the closing rail 14 entrains the actuating lever 11, with the weather protection cover 5 being closed. At the end of the closing movement the latching projection 16a automatically engages behind the co-operating latch means 17 so that the actuating lever 11 is locked. The weather protection cover 5 is th~L~LoL~ not only closed but at the same time also locked to prevent it from being undesirably opened by wind.
In the opposite station the actuating roller 12' runs on to an opening rail 13, whereby firstly the latching pawl 16 of the double 2~6~ ~2~
pivot lever is pivoted relative to the actuating lever 11 into the position shown in broken line and identified by reference numeral 18c. In that position a portion of the latching pawl 16 bears against the abutment b of the actuating lever 11. Frcm that position the latching pawl 16 entrains the actuating lever 11 and the weather protection cover is opened, until the double pivot lever is in the position identified by reference numeral 18a.
The locking device according to the invention can be easily subsequently fitted to existing chair lifts, with no modifications being required at the stations. On the contrary the locking device, in accordance with a particular feature of the invention, is automatically actuated by the opening and closing rails which are already present in any case for the weather protection cover. The arrangement provides for operation~lly r~ hl~ locking of the actuating lever on the suspension bar.
When an occupied chair leaves the station, it is deemed desirable for the weather protection ccver not to be necessarily closed. That does not endanger the passengers and the passenger can intentio~lly leave the weather protection cover open. For that purpose the closing rail 14 only needs to be pivoted out of the region of the actuating roller 12'. If now the passenger closes the weather protection cover while the chair is on the cable between the stations, the actuating lever 11 pivots into the position shown in solid lines in Figure 2, without that involving a change in the relative position of the latching pawl 16 with respect to the actuating lever 11. In the ~Rnll~lly closed position thel~LoL~ the latching pawl 16 is in the position which is identified by reference numeral 18c and in which it does not engage behind the co-operating latch means 17. Therefore, there is intentionally no locking effect when the weather protection cover is closed m~nll~lly, in order to permit the passenger to open the weather protection cover at any time.
Figures 3 and 4 show a further embodiment of the double pivot lever according to the invention, the same reference numerals identifying the same or equivalent components as in Figure 2. In the embcdiment shown in Figures 3 and 4, the actuating lever 11 which is of a cranked configuration is mounted on the holder 21 pivotably about a pivot axis 20. me diayL~",~Lically indicated spring 22 is not essential in regard to the mode of operation of the arrangement and only serves in a fault situation to prevent ; n~mi ~sible pivotal movement of the actuating lever into the clear space profile which is to be kept free. The second part of the double pivot lever, namely the latching pawl 16, is shown in solid lines in Figure 3 in the position in which it is locked to the co-operating latch means 17.
The abutments which are required for operation of the arrangement and which restrict the relative pivotal movement of the latching pawl 16 with respect to the actuating lever 11 are provided in the embodiment shown in Figures 3 and 4 by the actuating lever 11 having a slot 23 in which a pin 24 which is fixedly connected to the latching pawl 16 is movable. The two ends of the slot 23 form the abu~l~nLs for restricting the pivotal movement as between the latching pawl and the actuating lever.
The embodiment shown in Figures 3 and 4 also has as a further particularity a movable co-operating latch means 17 which is spring-loaded towards the latching pawl 16. In that arrangement the co-operating latch means 17 is in the form of a pin projecting from a pivotable lever 25 wnichis spring-loaded by a spring 26 in the direction indicated by the arrow 27, that is to say towards the latching projection 16a. An abutment (not shown) restricts the pivotal movement of the lever 25 in the direction of the arrow 27 when the latching pawl 16 is disengaged. The resilient mounting of the co-operating latch means 17 has the advantage that engagement of the latching pawl which is absolutely satisfactory from the functional point of view is possible. When the latching pawl pivots 2~
apen, the spring-loaded co-operating latch means can firstly ~ ve back from the outside of the latching projection 16a into the position shown in broken lines in Figure 3, against the spring loading. When the latching pawl 16 reaches the end position, the co-operating latch means 17 automatically comes into ~n~rping engagementunder the latching pawl, thus producing the locking action.
Finally, the embodiment shown in Figures 3 and 4 also has the feature that the pivotal connection between the actuating lever 11 and the latching pawl 16 is intentinn~lly made difficult to move in order to prevent unintentional relative pivotal movement as between the latching pawl 16 and the actuating lever 11, other than upon actuation by the opening or closing rail. That difficulty of movement in relation to the above-indicated connection can be achieved for ~x~mrl~ by the two lever portions 11 and 16 being resiliently pressed against each other so that the friction between them is increased. In the ~mhc~impnt shown in Figures 3 and 4, a spring 29 is provided for that purpose, which spring can be ~lesLlessed by way of a nut 28.
As already mentioned in the opening part of this specification, the locking device according to the invention is suitable in parti~l1Ar for cover-type chairs, that is to say chairs with weather protection covers.
In principle however it is also conceivable and possible for such a locking device to be used to advantage in relation to cable ~r l;fts. The embodiment shown in Figure 5 ill~sLldLes a conrlp~hle cable car 30, the door 31 of which can be automatically apened or closed in the stations. Such opening is effected by way of an actuating device which is associated with the cable car and a tr~ncmi~sion means of which only the upper region is illusLlaLed. The Ll~ si nn means as such, that is to say the Ll~ ",i~sion of the pivotal movement of the actuating lever 11 to an opening or closing movement of the door, is well-known to the man skilled in the art and -2 ~
therefore does not need to be described in detail herein. Once again the arrangement has the double pivot lever ccmprising the actuating lever 11 and the latching pawl 16, by way of which locking of the doors is possible automatically when the doors close. The mode of operation of the double pivot lever shown in Figure 5 is the same as that of the double pivot lever shown in Figure 2.
