Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ski slope system consisting of a trough-shaped slope runway and a roller sled, in which a horizontal axis is attached to the front end of a base frame that holds a seat. A footrest with a sliding shoe is pivotably mounted around the seat, and a pair of wheels are arranged on the seat and a pair of sliding shoes are arranged on the rear side of the seat. , and furthermore relates to a type in which a brake member is arranged, which can be lifted off the slope by pushing forward a sliding lever arranged in front of the seat.

PRIOR ART A piste system of the above type consisting of a piste runway and a roller sled is known from DE 25 15 994 A1.
Another piste system having a trough-shaped piste runway but in which sliding sleds are used is described in US Pat. No. 3,858,517.
Similarly, the pine-like light structure sliding sled, which can be braked with a sliding lever, is equipped with a hook.
The sled can now be hooked onto the seat of the seat lift that leads from the base station of the ski slope to the summit station.
However, this type of transport for sliding sleds does not avoid the risk of the sliding sleds unintentionally coming off the seat and slipping, so it is not used for stable roller sleds of West German Patent Application No. 2515994 or similar structure. I can't.

Furthermore, according to DE 24 36 347 A1, it is known to transport roller sleds, sliding sleds or similar sleds to the top of a mountain by means of a ski lift, with skiers still on board. In this case the sleigh is releasably connected at one end to a grip rod attached to the free end of the traction rope. This type of transport is less expensive than the previously mentioned transport types;
Although less dangerous, since the tow run is carried out on a natural tow surface, it is likely to be hindered by natural obstacles, and in this case too an additional Workers are needed.

Problem to be Solved by the Invention The problem to be solved by the invention is that, in a sliding system of the type mentioned at the outset, it is necessary to provide a roller sled that is comfortable for the runners and safe for the spectators. To enable transportation from a destination to a starting position on a ski slope runway, and to prevent maintenance costs and personnel costs of the ski slope system from becoming excessively high.

Means for Solving the Problem The problem to be solved by the present invention is to have a traction lift leading to a foot station of a ski slope runway and a traction path laid under the traction rope, and the traction path is connected to a pair of wheels. and a pair of sliding shoes, it has a left side rolling/slideway and a right side rolling/slideway, and the roller sled is arranged in the intermediate space between both rolling/slideways. A guide web for the guided guide strip and a longitudinal passage through which the brake elements of the roller sled pass without coming into contact with the traction track are provided, and a traction rod with a grip rod on the rear transverse axis and free end of the roller sled is provided. An eye-hook traction coupling device is provided between the rope and the coupling of this eye-hook traction coupling device is carried out manually at the starting position and automatically activated at the destination, placed in the towing path. This problem was solved by the device being configured to be released by a locking and unlatching device.

According to US Pat. No. 3,363,583, a double towway consisting of plastic towway segments is laid under the tow rope of a tow lift primarily for skiers, with the left and right towways separated by a central web. However, this known technique does not suggest a solution to the problem that the present invention seeks to solve. In other words, in this case the important precondition of transporting the roller sled reliably is missing.

According to one embodiment of the invention, both rolling and sliding tracks are inclined towards the center of the traction track, depending on the position of the wheels and the sliding shoes. Moreover, when the towing hook is attached to the grip rod, the towing eye is vertical, and when the towing eye is attached to the grip rod, the towing hook is attached horizontally to the transverse axis, and the towing eye is wide. , has an opening that tapers gradually in the direction of tension. The first purpose of such an arrangement is to automatically ensure reliable uncoupling at the destination, and the second purpose is to ensure manual traction coupling. In order to avoid unintentional release of the towing connection during towing, but to make the towing connection easier, the tow hook attached to the grip rod should be aligned with the axis of the tow rope and the imaginary extension of the grip rod. It has a long hook tip bent outwards immediately after the point of action of the laterally offset traction eye.

Furthermore, in accordance with one embodiment of the invention, the unlatching device has a part surface that is vertical and inclined in the traction direction;
A coupling member attached to the grip rod of the traction rope rests on this partial surface and is spaced apart from the other coupling member by a lateral movement.

However, in order to ensure that the spacing takes place unhindered under all conditions, it is advantageous to provide a correction strip on the guide web. This correction strip brings the rearwardly tilted roller sled under the tension of the towing rope into its normal position before the separation process, bringing the wheels and the sliding shoes into contact with the towing path.

To increase the safety of skiers during towing, a detent brake is placed on the roller sled.
This detent brake has a brake member which is swingable in only one direction, the corresponding surface of which is formed by the surface of the guide web. U.S. Pat. No. 1,785,989 discloses a detent brake for a wagon running on a riseway and a fallway. These brakes cooperate with racks placed at dangerous points on the road.

The invention will now be explained with reference to the drawings: As can be seen from FIGS. 1 and 3, a roller sled slides on wheels 6 and sliding shoes 7. FIG. Sliders place their feet on a footrest 3 installed in front of the roller sled. This footrest 3 slides on a footrest sliding shoe and is pivotable around a sliding lever shaft 5 in a roller sled. The sitting part 1 is provided with an upwardly raised backrest part and a front seat part. When a skiing passenger pulls the sliding lever 2 toward him and moves the brake lever welded to the sliding lever shaft 5 and the brake rod 23 downward, the brake member 8 is pressed against the tram-shaped runway 16.

The axle 9 is moved forward or backward along the axle holder 101 depending on the slope of the runway. In the desired position the axle 9 is welded or screwed to the axle holder 101 and the automatic detent brake 11 necessary in the towway 18 ensures that its brake member 26 does not touch the bottom in the runway 16. It is arranged like this.

The guide strip serves to secure the roller sled 10 to the towing path 18. The force acting on the brake member 8 is preloaded in this embodiment and is applied to the axle 9 at one end and to the brake rod 23 at the other end. Centrifugal brake 14
is screwed to the outside of one wheel 6.

FIG. 2 is a rear view of the roller sled of the present invention in a standard runway 16. The brake member 8 is lifted from the runway 16, whereas the sliding shoe 7 and the wheels 6 are supported on the runway 16.

FIG. 3 shows a traction path 18 located below the traction lift 17. The skiers sit backwards on the roller sled 10.
is pulled up toward the mountaintop by the tow lift 17 to which it is hooked. The roller sled 10 slides on a towway 18 having left and right side rolling/slideways 18a and 18b. The traction path 18 is supported by a support girder 19
It consists of road segments made of high grade steel held together by. The support beams 19 themselves are screwed onto the sleepers 20. Sleepers 20 are wedge-shaped nails 21
may be additionally fixed.

FIG. 4 shows a cross section of the traction track 18, which is supported on support beams 19 which are connected to sleepers 20 via screws. In addition to having a supporting effect, the supporting spar 19 has a shape adapted to the traction track 18, so that the track segments inserted into the supporting spar 19 can mutually interact laterally and upwardly. to prevent movement.

On both sides of the guide web 25 the guide strips 12 of the roller sled 10 slide. As a result, the roller sled is guided precisely in the center of the towing path 18. Due to the dovetail configuration of the guide web 25 as shown, there is no need to reduce the supporting surface of the guide strip 12 between the rear horizontal axis of the roller sled 10 and the central portion 24 of the guide web 25. More intermediate chambers can be obtained. The availability of such a space makes it advantageous to arrange the traction eye 13 on the roller sled 10 and to arrange the unhooking roller 13 (see FIG. 12) at its destination.

A vertical passage is formed between the side wall of the guide web 25 and the rolling and sliding paths 18a and 18b for the wheels 6 and the sliding shake, so that the brake member 8
does not come into contact with the traction path 18, regardless of the position of the sliding lever 2.

FIG. 5 shows the automatic detent brake 11 in side view. In this case, the inactive state is shown on the left and the active state is shown on the right. Detent brake 1 with brake member 6
1 is swingably fixed to the wheel shaft 9. In this case, the detent brake 11 is constructed in such a way that in the active position it lies as perpendicularly as possible on the guide web 25 as the active surface of the detent brake, and the pivot point is located on the footrest 3. It is shifted and placed towards. The fact that the detent brake in the active state is substantially perpendicular to the working surface ensures that the detent brake engages even on steep towpaths.

FIG. 6 shows the towing eye 13 fixed under the rear transverse shaft 24 and the towing hook 27 in the tensioned position in cross section. The traction eye 13 is constructed in such a way that it provides a sufficiently large opening for the rapid engagement of the traction hook 27 and ensures sufficiently precise guidance of the traction hook 27 in the tensioned position.

In FIG. 7, the towing hook 27 is shown in plan view. The curvature of the hook is chosen such that the traction hook 27 is well retained in the traction eye 13 and, on the other hand, relatively easily pushed out of the traction eye even under tensile loads. For this purpose, an elongated hook tip, which is bent opposite to the direction of curvature of the hook, is useful. Towing hook 2
The above-mentioned curvature of 7 is caused by the fact that the tip of the hook at the towing eye 13 pivots downward under the weight of the grip rod 28 fixed to the towing rope 17a.
It is elongated as occurs when the tension is released during towing. It is believed that if the towing hook 27 were introduced into the grip rod 28 without a bend, the tip of the hook would pivot upwards and slip unintentionally from the towing eye 13.

In FIGS. 8 and 9, the eye-hook traction coupling device 13, 27 is shown in plan and side view. This eye hook traction coupling system operates as described in connection with FIGS. 6 and 7. However, in this case the positions of the towing hook 27 and the towing eye 13 are interchanged. That is, the traction hook 27 is fixed to the roller sled 10 and the traction eye 13 to the grip rod 28.

FIG. 10 shows a roller sled 10 in a longitudinal section on a schematically illustrated towpath 18. Owing to the diagonally upwardly directed pulling force of the grip rod 28, the rear transverse shaft 24 with the sliding shoe 7 is tilted upwards about the wheel axle 9. As a result, the towing hook 27 and the towing eye 2
The position 8 is also moved upward so that the tip of the traction hook slides above the hooking and unhooking roller. Therefore, automatic disconnection is not performed at the destination.

FIG. 11 shows the same situation as in FIG. 10, but in this case the running lever shaft 5 is under the action of two tapered correction strips 29 mounted on the guide web 15. Therefore, at the same time as the vehicle is tilted upward about the wheel shaft 9, the rear horizontal shaft 24 is tilted downward, so that both shafts are moved in the same plane. In this state, the towing eye 13 and the towing hook 27
is located within the action range of the unhooking roller 30, which ensures automatic unhooking.

FIG. 12 shows the guide web 25 with attached correction strip 29 and the unlatching roller 30 to which the roller sled 10 approaches in a plan view.
When the movement in the direction of the arrow continues, the tip of the traction hook 27, the trajectory of which is precisely defined in advance by the guide strip 12 and the correction strip 29 arranged on the roller sled 10, will release the hook from the unhooking roller 3.
0, and is automatically pushed out from the traction eye 13 by this hooking/unhooking roller 30. In order to prevent the hook tip of the traction hook 27 from pivoting upward and passing past the hooking/unhooking roller 30, the upper edge of the correction strip 29 is projected inward just before the hooking/unhooking roller 30, and the hook tip of the traction hook 27 is The tip of the hook 27 is designed to prevent escape.

In FIG. 13, the traction channel 18 with the guide web 25 is shown in section in a direction opposite to the traction direction. The rear transverse shaft 24 together with the traction eye 13 and traction hook 27 is located just in front of the hooking and unhooking roller 30. Shown in dashed lines at the unlatching roller 30 is a correction strip 29 having an extension of the hook tip of the traction hook 27 and an inwardly flared upper edge. The inwardly projecting upper edge of the correction strip 29 prevents the tip of the tow hook 27 from escaping upward. Additionally, due to the inclined mounting of the towing eye 13 (approximately 5°), the towing hook 27 is directed downwards, so that the tip of the towing hook 27 slides over the unlatching roller 30. is prevented.
