• a recreational apparatus 10 intended for an activity which simulates skiing.
• the recreational apparatus can be modified, if and as necessary, to accommodate other activities of the type referred to above.
• the apparatus 10 comprises a hollow body 11 defining an interior chamber 12.
• the hollow body 11 is in the form of a drum having a cylindrical side wall 13 and open end walls provided by the lips 17 each of which extends radially inwardly from the respective end of the cylindrical wall and surrounds an access opening 19.
• the cylindrical side wall has an inner face 21 and an outer face 23.
• the drum 11 is supported for rotation about its central longitudinal axis on support means 25 in the form of a plurality of rollers 27 which provide a supporting cradle for the drum, with each roller in contact with the outer face 23 of the drum.
• Drive means (not shown) are provided for selectively driving at least one of the rollers 27 thereby to cause rotation of the drum 11 about its central longitudinal axis.

• the user 40 can ski within the chamber 12 for some time without moving any significant distance relative to the outside stationary point.
• the user can, however, vary his or her position, and direction of travel, so as to move about the surface 22 as it rotates.
• the user 40 may, for instance, assume a direction of travel transverse to the direction of movement of the surface, in which case the actual movement of the user relative to the stationary point would be the resultant of the movements in the two directions. Indeed, with appropriate conditions it may be possible for the user 40 to move axially along the chamber 12 from one end of the drum 11 to the other end without any ascending or descending movement relative to the stationary point.
• a screen 43 is provided within the chamber 12 so that the user 40 is in facing relationship with the screen, as shown in Fig 1. Images can be projected onto the screen 43 which the user 40 can view while skiing.

• the poles 45 are in spaced apart relationship around the gliding surface 22 so as to provide a slalom course through which the user 40 may pass while skiing within the chamber 12. This is particularly advantageous as it provides a lengthy slalom course which is of compact nature and along which the user 40 can continuously ski for the duration of the time in the apparatus.
• the apparatus according to the third embodiment is again similar to the first embodiment with the exception that there is a harness structure 50 by which a user can be supported, and no screen.

• Fig 5 shows another embodiment in which drum 11 is not in the form of a right cylinder but rather is in the form of a truncated cone.- With this arrangement, the cylindrical side 13 provides an inner face 21 which presents an inclined gliding surface 22. In this embodiment, the drum 11 can also be tilted about pivot axis 71 at one end thereof under the influence of a tilting ram 73. In this way, the inclination of the gliding 22 surface can be changed prior to, or even during, the skiing activity.

• the user 97 is able to ski with little movement relative to a stationary point remote to the apparatus.
• the user is, of course, also able to move transversely of the upwardly moving gliding surface 95 and thereby travel along a weaving course.
• the direction that the endless deck 81 is caused to rotate may be reversed so that the gliding surface 95 descends (rather than ascends) in circumstances where the user wishes to ski in an uphill mode.
• Fig 7 of the drawings shows an embodiment which is somewhat similar to the embodiment of Fig 6 with exception that it is composed of a plurality endless deck sections 101 each of which is of similar construction to the endless deck 81 and each of which can be driven independently of the other.

• one or more of the deck sections 101 can be arranged to rotate in a direction opposite to the intended direction of travel of the user 107 so as to influence movement of the user by opposing the direction of travel of the user, as previously described in earlier embodiments.
• the arrangement does, however, also allow for at least one of the deck sections 101 to be rotated in a direction which would correspond to direction of travel of the user and so assist in rapidly moving the user along that particular deck section.
