Abstract

Harnais utilisé pour apprendre le ski de piste comprenant une ceinture (1) dotée de deux sangles de type camisole (3, 4) dont la première extrémité est fixée à l'arrière de la ceinture (1) et l'extrémité opposée est fixée sur la face avant de la ceinture (1), la face de ladite ceinture (1) étant également dotée de moyens d'attache (5), de préférence des anneaux, lesdits moyens d'attache (5) permettant de préférence un réglage de la circonférence de la ceinture. Deux cordes de commande, des sangles, des bâtons rigides ou similaires (6, 7) sont temporairement attachés au niveau de leurs premières extrémités au moyen d'attaches (5), les extrémités opposées des cordes de commande comportant des poignées, des sangles ou des poignées à enrouleur offrant une prise au moniteur. Lorsque le moniteur saisit les cordes de commande, il empêche l'élève de s'éloigner tout en lui apprenant à effectuer un mouvement de balancement des hanches en tirant une des cordes de commande (6, 7) forçant ainsi la hanche de l'élève à se balancer d'un côté. De plus, la ceinture peut être pourvue de bretelles (9, 10) afin d'empêcher que la ceinture ne tombe aux jambes, par exemple lorsque l'élève tombe vers l'avant.Harness used to learn piste skiing comprising a belt (1) provided with two camisole-type straps (3, 4), the first end of which is fixed to the rear of the belt (1) and the opposite end of which is fixed to the front face of the belt (1), the face of said belt (1) also being provided with attachment means (5), preferably rings, said attachment means (5) preferably allowing adjustment of the waist circumference. Two control ropes, straps, rigid sticks or the like (6, 7) are temporarily attached at their first ends by means of fasteners (5), the opposite ends of the control ropes comprising handles, straps or retractable handles providing a grip for the monitor. When the instructor grasps the control ropes, he prevents the student from moving away while teaching him to perform a swinging movement of the hips by pulling one of the control cords (6, 7) thus forcing the student's hip to swing to one side. In addition, the belt can be provided with suspenders (9, 10) in order to prevent the belt from falling to the legs, for example when the pupil falls forward.

Description

Training harness for teaching downhill skiing.

The present invention concerns a harness device, particularly suitable for teaching children downhill skiing, in accordance with the introductory part of claim 1. Usually, children learn downhill skiing by a person holding them between his legs and grabbing their shoulders, thus teaching how to turn and to control the skis. By teaching in this way, a problem arise because the pupil will not learn to turn the hip in a proper way, an essential element in slalom. Moreover, if one of the actors loose control or if the instructor loose his grip when out of balance for a moment, a risk exist that they fall upon each other. A risk may then arise that the pupil will run away in to dangerous areas.

DE Patent Application no. 35 21 146 describes an attempt to remedy some of these problems. The pupil is provided with a waist belt comprising mounting or securing means in the back of the belt for connection with a rope. A grip is connected to the other end of the rope to provide control for the instructor. Thus, the instructor will avoid that the pupil runs away downhill on his own.

The object of the present invention is to provide such a harness for teaching e.g. children, minimizing the risk of the pupil and the instructor both falling or the pupil run away alone, and at the same time provide control of the pupil's hip swing in order to teach the pupil the basic skills of slalom technique in a faster way. This object is fulfilled in accordance with the characterizing part of claim 1. Further features appears from the independent claims.

In order to achieve a better understanding of the invention, figures are enclosed, in which Figure 1 illustrates one embodiment of the invention including a part of the accompanying control ropes, Figure 2 illustrates an alternative embodiment of the harness, in which further an alternative is indicated with dotted lines,

Figure 3 illustrates the embodiment in accordance with Figure 1 , but provided with shoulder harnesses, and

Figure 4 illustrates the harness in use. The invention is characterized in a harness or belt 1 provided with a tightener 2, to fasten the belt around the waist/hip of the pupil. In order to avoid any rotation of the harness around the hip, two straps, ropes or the equivalent 3, 4, are attached, which in the direction of motion downhill are arranged substantially parallel with the latter. The straps are preferably attached beyond and at a certain distance away from the side of the central part of the waist belt 1, respectively, so that the respective straps 3 and 4 extend downwards and forwards in the direction of downhill motion, and upwards to the front of the waist belt 1. These camisole straps may be fixedly attached to the front of the waist belt, or attached by means of e.g. snap couplings or hooks. In addition should at least one of the securing means for each camisole strap be provided with a tightener 8, such as a belt buckle, to secure the waist belt down to the hip sockets. When the waist belt is secured to the hip, the belt will stay fixed to the hip and will not rotate when one attempts to turn the belt relative to the body. Moreover, the waist belt 1 will not be pulled upwards to the chest when the instructor is elevated relative to the pupil (Fig. 2). In an alternative embodiment, the camisole straps may be crossed, so that the respective straps 3 and 4 are terminated at the opposite side in front of the belt, in view of the direction of motion downhill, resulting in an improved hold of the waist belt against sideways turning compared with non-crossed camisole straps. Moreover, the camisole straps 3,4 may at a location between the back and front side be joined to provide one single strap 3+4, which preferably is attached to the front by means of a belt buckle, snap couplings or similar 8 to the waist belt 1.

Securing means 5, such as hooks, are fixedly attached to the waist belt 1. Two control ropes, wires, rigid sticks or similar 6, 7, are attached to these securing means. The control ropes may be fixedly attached to the belt 1 or the securing means 5, or attached with hooks or snap couplings to the securing means 5. The control rope securing means 5 should not be positioned -further back or forward of the waist belt than a controlled rotation of the pupil by dragging one of the ropes is obtained. If the attachment means 5 are positioned at a certain distance in front of the side of the waist belt relative to the direction of motion downhill, a pulling action backwards in the securing means in a direction opposite the direction of motion downhill, will result in a longer hip turning distance in relation to securing means positioned at the side or beyond the side of the waist belt.

If the control device 6, 7 is provided as rigid sticks, the sticks should be attached to the waist belt in such a way to be rotatable around the stick axis without affecting the belt. The instructor's hands may then be oriented in any position independent from the position of the pupil. The length of the control ropes or control sticks may be from 1.5 to 6 m, preferably 3 m. The control sticks or ropes may in their respective ends opposite the waist belt be provided with some sort of a grip, ropes or similar, (indicated in Figure 2) to provide a proper grip to the instructor.

In further an alternative embodiment (not illustrated), the control ropes are at the instructor's end provided with a grip provided with a clamp device or tightener. This may be carried out by making two holes in a relatively thin plate, through which the respective control ropes may be guided. In such a case, the control ropes are preferably guided in at one side and out at the other side. A strap or a grip may be attached to this plate, to provide a grip for the instructor. When the rope is loaded with force, the rope will be drawn tight to the edge of the hole so as to avoid the rope to slip out from the plate. By means of simple hand adjustments, the rope length can be increased or decreased to adjust the rope length in accordance with the skill of the pupil or the hill slope. An alternative embodiment of the grip means of the control ropes is a reel grip known from dog collars. The instructor can also in this case increase or decrease the length of the control ropes with a simple hand adjustment to adjust the rope length to the hill and the pupil.

The hip harness may in addition be provided with shoulder straps 9 and 10, of a generally common type, as illustrated in Figure 3. If the pupil falls forwards so that the belt will be pulled downwards to the legs, the shoulder straps will accordingly ensure that the hip harness will stay in place. Moreover, if used on handicapped persons, the shoulder straps will further stabilize the pupil. The shoulder straps can be further stabilized by joining the two shoulder straps 9 and

10 in front to an adjustable chest belt in a manner known per se (not illustrated). Further alternative embodiments of the shoulder straps may be provided, such as two separate belts 9 and 10, which in the back area are connected by a cross member.

In another embodiment, the hip harness including camisole straps are sewed into a downhill clothing or similar.

Moreover, the respective control ropes may be wrapped around the front of the belt and thereafter back to the instructor. In this way, the instructor will be able to obtain a longer hip turning distance of the pupil.

The present invention is in particular concerned with training of children in downhill skiing, but may also beneficially be used with handicapped individuals, such as blind persons, both in connection with training and to make downhill skiing more convenient. In both cases, the present invention will enable training in a steeper hill than if the pupil for example is placed between the instructor's legs.
