Abstract
ABSTRACT
An exercise device for a cross-country ski training consisting of a frame carrying four parallel tubular members, of which the intermediate tubular members support two saddles which in turn have a pair of skis firmly fastened thereto. The lateral tubular members support two slides on which the tubular supports for the ski poles are lodged. The ski-carrying saddles and the ski poles-carrying slides are all connected with only one flexible driving element which may be a rope, a chain or a belt sliding under the frame on suitable guides. Due to such a connection, a forward movement in one direction of one of the ski-carrying saddles corresponds to an equal movement of the other saddle in the opposite direction. A simultaneous, equal and discordant movement of the slides which carry the ski poles is obtained.

Description
:~2~.9~
The invention provides a mechanical device which is adapted for doing, with a pair of ski and suitable shoes, a presoaking exercise particularly suitable for a cross -country running ski ~langlauf) training. To be efficiently done, cross-country running ski, like any other sport, needs suitable physical training.
In fact, this sport requires first of all physical strength and training of the leg and arm muscles, especially when an athlete desires to cover a long distance, comprise in flat stretches and uphill and downhill stretches.
Presently, the preparation for this sport takes place mainly in a gymnasium and comprises special free-standing exercises for strengthening the leg and arm muscles and for causing certain particular muscles to work under conditions simulating the actual conditions.
Specific devices adapted for a cross-country ski facing training are not known to the Applicant, and do not appear to be on the market, so that those desiring to have recourse to the aid of mechanical devices are compelled to use an exorcise bicycle, a rowing machine or the like, but all these deviees,although athletically preparing certain muscles, do not simulate the actual conditions that are produced when engaging in crosscountry ski racing.
A matter of particular importance is the coordination of the arm and leg movements, which in cross-country ski facing is carried out in a quite particular manner, and certainly differs, for example, from movements which are obtained with a rowing machine.
I
. -- 1 The object of the present invention is a mechanical device for simulating with the utmost accuracy coordinated leg and arm movements typical of cross-country ski; and particularly the alternating step which is the typical movement performed on flat or slightly sloping ground.
A further object of the invention is that the gymnastic leg and arm movement is to be performed while wearing skis and boots, and while gripping the ski poles, in order to create with the utmost possible accuracy the effective operating conditions.
These objects are attained by a manually movable implement comprising a frame which is formed by four longitudinal tubular members, preferably square or rectangular in cross-section, and by two connecting cross bars, and is characterized in that two saddles which are slid able on the intermediate tubular members, and support a pair of skis, perform alternately opposite forward and backward movements according to an adjustable excursion thereof, the said saddles being connected with only one flexible driving means sliding under the frame on suitable guides, so that to a forward movement in one direction of one of the skis there corresponds an equal backward movement in the opposite direction of the other ski.
According to the invention, the two outer tubular members of the device, which are parallel to the intermediate tubular members, carry two slides which are slid able on the said tubular members. Connected by means of a hinge to each one of the slides there is a small socket for receiving the point of a ski pole. Also, the slides are fastened to the flexible means consisting of a chain, a rope, or a toothed belt, whereby they are given as well an alternate discordant movement.
. t I
The movements of the skis fastened to the saddles and of the ski poles fixed to the slides, which are coordinated by the flexible means located under the frame, exactly reproduce the arm and leg movements typical of the alternating step in cross-country skiing.
According to a broad aspect of the present invention there is provided a device for presoaking training for cross-country skiing. The device comprises four parallel tubular members preferably rectangular or square in cross-section and including two lateral and two intermediate members. The four tubular members are rigidly mounted on two cross bars. Two saddles are slid able on the intermediate tubular members. The saddles perform movements of the same length but in opposite directions up to an adjustable maximum length of travel. The saddles are connected with a single flexible driving means sliding under the frame on guides.
Two slides are slid able on the lateral tubular members and are connected through hinges to ski pole supports performing discordant movements of the same length as the movements of the ski-carrying saddles. The slides are also connected with the flexible means.
`- A rail is formed by two main tubular supports hingedly connected -to a forward cross bar of the device. A
C-shaped tubular bar is fitted into the free ends of the main tubular supports and are upwardly pull able and lockable in position by means of two collars provided at the free ends of the main tubular supports, the latter being liftable through the unlocking and rollicking of two snap rings which by means of hinges are connected to rods, which in turn are also connected by means of hinges to horizontal bars welded to the forward cross bar.
Jo - 3 -Other features and advantages of the device of the invention will become more clearly apparent from the hollowing description of a preferred embodiment, given by way of a non-limiting example, and shown in the accompanying drawings, in which:

Jo - 3 -Other features and advantages of the device of the invention will become more clearly apparent from the hollowing description of a preferred embodiment, given by way of a non-limiting example, and shown in the accompanying drawings, in which:
FIGURE 1 is a perspective view of the device without the safety rail;
FIGURE 2 and FIGURE 3 show two different ways of attaching the stop members limiting the travel of the saddles;
FIGURE 4 is a perspective view showing one of the two ski-carrying saddles;
FIGURE 5 diagrammatically shows the path of the flexible means located under the frame, with which the slides and the saddles are connected;
FIGURE 6 is a sectional view showing one slide with the socket for receiving one ski pole; and FIGURE 7 is a further partial view of the device showing the safety rail.
Referring to Figure 5 and to Figure 1, a flexible means 1 which may be a rope of wire or synthetic fiber, a chain, or a belt with or without teeth, runs along a closed path and is supported by a pair of pulleys
2 secured to the ends of a tubular member 6, the pair of pulleys 3 secured to the ends of a tubular member 7, a pair of pulleys 4 secured to the ends of a tubular member 8 r and a pair of pulleys 5 secured to the ends of a tubular member 9. Saddles 10 and 11 which are slid able on the tubular members 7 and 8, and slides 12 and 13 which are slid able on the tubular members 6 and 9, are connected with the flexible means 1 through mechanical devices to be described later. Thus, to a forward movement in one direction of, for example, the saddle 10, there corresponds an equal forward movement of the slide 12, while a backward movement of the same length of the saddle 11 and the slide 13 occurs simulate-, nuzzle. Therefore, by fastening with suitable means the skis onto the saddles 10 and 11 and the ski poles onto the lateral slides, the alternating step typical of cross-country ski racing will be reproduced.
Actually, a person who mounts the device and locks his shoes to the special ski fasteners attached to the saddles, and inserts the ski poles into the sockets carried by the lateral slides, once he has made a single forward or backward movement with one foot, is induced by the device to move his legs and arms according to the alternating step.
Figure 4 shows the connection between one tubular member and one saddle, and between one saddle and the rope. More particularly, the saddle 11 is formed by a shopped plate which is slid able on the tubular member 7 having a rectangular cross-section, with the aid of a pair of rollers 14 and 15, provided with shoulders, and pivoted onto the saddle and roll on the upper surface of the tubular member 7.
Provided at the lower end of the plate is a further guide roller 16 also pivoted onto the saddle 11, which contributes in a determinative manner to the straight sliding motion of the saddle. A flat plate 17 provided with threaded bores 18, in which screws are received for clamping the platelet 19 against the rope 1, is located at the bottom of the tubular member 7 and is welded to the saddle 11. Thus, the connection between the saddle 11 and the lower rope 1 is ensured.
At its top the saddle 11 has two angles 20 and 21 which are welded to this saddle and are provided with screws 22 and 23 for fastening the ski placed on the saddle. It is important that the saddles 10 and 11 be provided with limit stop members, whereby the pace of the person using the gymnastic device will not exceed his physical possibilities. This is important particularly for children or generally for short-legged ... .^.~ _ So persons. Therefore, two limit stop members 24 are provided, which are placed at a same distance from the cross bars, and are arranged between the saddle-carrying tubular members so as to overlap same. Far the operation of the thus conceived device only one limit stop member would be required, since the two saddles 10 and 11 alternately abut against one limit stop 24.
The fact that instead of only one, two limit stop members are provided arises from the need of render-in the device as safe as possible, and free from any risks deriving, for example, from having been unsafely locked in position one limit stop.
In Figure 2 there is shown the limit stop member 24, which consists of a bar having two C-shaped recesses, such that the bar can be placed astride of the tubular members 7 and 8. In the case of Figure 2, the locking in position of the limit stop member 24 is effected through the pressure exerted by the tightened screws 25 and 26.
A variant shown in Figure 3 provides for the bar 24 to be blocked by means of screws which are received in matching bores 27 and 28 in the bar-supporting tubular members 7 and 8.
As above mentioned, the slides 12 and 13 carry the sockets into which the ski poles are to be inserted. As particularly shown in Figure 6, the slide 12, which by means of a Teflon* bearing 36 is slid able on the tubular member 6, has an attachment member 29 to which a shaped socket 30 capable of receiving the point of a ski pole 31, is hingedly connected at 35.
A screw 32 guarantees the fastening to the socket of the ski pole.
* Registered trademark lo The driving of the slides is achieved by means of shaped platelets which clamp the underside of the rope 1, and which are secured with screws to each slide. In Figure 6, the slide 12 is made integral with the driving rope 1 by means of the shaped platelet 37 which sets the rope against the slide when the screws 38 and 39 are tightened.
By such a connection, the ski pole has only two degrees of freedom, which correspond to the reciprocal tying straight motion of the slide 12 and to the pivoting of the socket 30 about the hinge 35.
The gymnastic device is provided with a further safety device consisting of an adjustable tubular rail having its upper end approximately at the level of the waist of the person using the device. This rail, which as a whole is designated by 40 in Figure 7, is formed by two tubular main supports 41 and 42 which are hingedly connected at 44 and 45, respectively, to the fore cross bar 43 of the device, and by a C-shaped tubular bar 46 having its ends fitted into the tubular supports 41 and 42. The tubular bar 46 is adjustable in height by pulling up and fixing same by means of two lockable collars 47 and 48 with a known toggle device.
Moreover, the rail 40 is liftable according to particular requirements and in relation to the user by unlocking the rings 49 and 50 which, through a hinge, are respectively connected to the rods So and 52, and are also provided with locking toggle means. The rods 51 and 52 are in turn hingedly connected at 53 and 54, each to one bar 55, 56 welded to the cross bar 43. Thus, once the rings 49 and 50 have been unlocked, the rail 40 can be pivoted both forward and backward about the hinges 44 and 45, and once the preferred position has been set up, rollicking of the rings 49 and 50 guarantees the stability of the selected position.
! ' ' ' The necessity of the rail I resides in the fact that the person being trained on the device may happen to make some impetuous movements, with the result of throwing his body out of balance in the forward direction, so that it is important for the tubular bar 46 of the rail to provide additional support for the body.
It will be understood that numerous changes of constructional nature may be made in the device without departing from the invention. Such changes may relate to the mode of fastening the saddles and the slides to the flexible means which, as disclosed, may be a rope, a chain, or a belt with or without teeth;
the number and the shape of the rollers for the saddles may be changed; and the rollers for the saddles may be replaced with equivalent mechanical means.
