Abstract: The vehicle is intended as a self-propelled utility model for beach cleaning. It has a vehicle frame which comprises at least one front and rear axle. A garbage pickup is disposed therebetween. The vehicle is to be a multi-purpose vehicle. The vehicle frame equipped with wheels consequently has a centric, rectangular opening between the front and the rear axle. The garbage pickup is adjustably mounted in this opening, namely from an operating position in which it contacts the ground to a ready position in which it is lifted from the ground. Seen in the direction of driving, a collecting receptacle for the picked up garbage is located behind the garbage pickup.

Abstract: A fold-away table is provided for a seat in a vehicle, particularly a motorcoach. The table comprises a mounting structure disposed laterally of the seat, and a carrier structure mounted for displacement in a vertical plane between a lowered storage position and a raised use position. The carrier structure includes a pivot axis having at least one table element mounted thereon. A fold-away table of this type should be readily operable and protected from soiling. To this purpose the mounting structure is formed as a stationary vertical guide structure. The carrier is formed as a guided housing structure containing the table element and permitting it to be displaced between the use position and the storage position. The pivot axis extends substantially horizontally within the housing structure.

Abstract: The invention relates to a hydraulic control system for changing the speed and direction of a hydraulically operated tracked vehicle (1). The hydraulic control system is equipped with a feed pump (34) for the control fluid and with hydraulic undercarriage pumps (12) and (13). The undercarriage pumps (12) and (13) comprise regulating cylinders (18) and (19) subjected to the control fluid and intended for adjusting the pump pivoting angle. The regulating cylinders (18) and (19) are each equipped with two regulating-cylinder chambers (26, 28) and 25, 27) separated from one another by a regulating piston (22) and (23).

Abstract: The invention relates to a snow tiller for mounting on the rear of a track maintenance vehicle. The snow tiller comprises a tiller shaft and a tiller frame of at least triangular cross-section extending over the width of the snow tiller and having end plates for supporting the tiller shaft bolted to its lateral ends.In order to facilitate the maintenance of the snow tiller, the lateral ends of the tiller frame are provided with bars secured thereto in a V-shaped configuration. Secured to each end plate at its side facing towards the tiller frame is a pair of undercut bars in a V-shaped configuration for overlapping engagement with the bars on the tiller frame in the mounted state of the end plates. The undercut bars cooperate with a fixing bolt engaging the tiller frame to form an interlock clamp mounting arrangement.

Abstract: The present invention relates to a snow tiller for rearmounting on a track maintenance vehicle. The snow tiller comprises a transmission for driving at least one tiller shaft, a carrier frame for mounting the snow tiller on the track maintenance vehicle, and a baffle body of trapezoidal cross-section extending over the width of the snow tiller. A levelling attachment is secured to the underside of the baffle body facing the track surface.With a view to facilitating repair and maintenance operations and replacement of wear components, the baffle body is formed as a tubular profile member forming a central tiller frame. The transmission is mounted at the center of the tiller frame and drives to tiller shafts laterally connected to the transmission. The ends of the tiller shafts facing away from the transmission are mounted in outer bearings secured to the ends of the tiller frame.

Abstract: A rotary tiller for maintaining cross country ski trails has a rotary shaft with at least one array of radially extending first cutters flanked by laterally adjacent arrays of radially extending second cutters. The radial lengths of the first cutters are greater than the radial lengths of the second cutters. The first cutters are arranged to till a center ski track and the second cutters are arranged to till pole tracks on either side of the ski track, with the ski tracks having a tilled depth greater than that of the pole tracks.

Abstract: An apparatus for forming cross country ski tracks in a snow covered surface has a trailer frame adapted to be connected to the rear end of a vehicle. A lifting frame is connected to the trailer frame for pivotal movement about a first horizontal axis. The lifting frame has a pair of parallel guide members extending longitudinally from the trailer frame to a transversally extending crossbar. The guide members are arranged symmetrically on opposite sides of a central axis common to the lifting frame, the trailer frame, and the vehicle. At least one cross country ski track forming device is connected to the crossbar for pivotal movement about a second horizontal axis. A positioning device is connected between the trailer frame and the lifting frame.

Abstract: An aerating system for faecal matter collected in a container in a vehicle which includes a pressurized air system for operating brakes, doors, ventilation flaps and the like. The pressurized air system includes a tank and a compressor which operates continuously during operation of the vehicle engine and a regulator which exhausts excess air to a bypass duct when the tank is at its operating pressure. A tube connects the container to the bypass duct so that faecal matter in the container is substantially continuously aerated during vehicle engine operation.

Abstract: A closure member for vehicle compartment openings is pivotally connected along its upper edge to the vehicle by a horizontal swivel axis and is horizontally divided into an upper and a lower closure member part, which parts are pivotally connected to each other along a horizontal connecting axis. A secondary pressure spring extends between the upper and lower closure member parts for effecting relative pivotal movement therebetween toward an intermediate position in which the closure member parts are substantially perpendicular. A lock secures the upper closure member part to the vehicle until the lower closure member part reaches the intermediate position. A main pressure spring extends between the vehicle and the upper closure member part for pivoting the closure member after release of the lock into an end position exposing the compartment opening.
