A gearshift device for electrically controlled transmissions is provided having a shifting lever pivotable in two parallel planes and guided in slides which have a connecting link only in the area of a neutral shifting position. Such gearshift devices are used particularly in construction machines. By way of a lock, which is activated below an admissible speed, a shift to the neutral position and into the opposite direction of travel is prevented. At higher speeds, accidental faulty shifts are prevented by a step-by-step gearshift mechanism. The locks, according to the invention, require only few regulation measures since they contain two mutually independent locking systems.

A ski guard is formed of an elastically tiltable stirrup made of a plastics material with a holding member formed as a part of the stirrup. The holding member maintains the stirrup member in the upright position on a ski by securing its support surface in contact with the upper surface of a base member which attached the stirrup to a ski. When the stirrup tilts or pivots, the support surface on the holding member moves over a boundary surface on the base member overcoming a dead-center position. Movement beyond the dead-center position takes place because of the deflection of a part of the holding member spaced from the support member. Axle journals in spaced axial alignment pivotally mount the stirrup on the base member and permit the location of a large locking element between them for detachably fastening the base member on a fastening plate.

A shift lever for the selective actuation of power tools on a utility carries a rotary and axially shiftable knob which can be indexed by ball checks in a plurality of angular positions to establish different speed ratios of the vehicular transmission by actuating respective microswitches through cams bearing upon mobile bodies which are lodged in apertures of a stationary collar surrounding an extension of the knob. A rocker switch on that knob can be flipped by the fingers of the operator to switch between forward and reverse drive.

The cross-country ski binding is provided with two pins (3, 4) which are arranged with their corresponding rigid pin recesses (5, 6) one behind the other in the longitudinal direction of the ski; at least one pin is spring-loaded in a perpendicular direction to the ski by a spring element (2) in the form of a binding arm. In this way, the design is maintained flat and the spring travel is long and spring fore can be optimally adjusted. Insertion of the foot in the binding is also facilitated and the stability of the ski boot (9) around its vertical axis is good and the binding grips without and play. With this design numerous advantageous embodiments of the biding are possible.

A reversing or direction-selector switch for a transmission of a motor vehicle having an electro-hydraulically controlled transmission unit which can be switched over from forward to reverse drive by the switch. According to the invention, a switch lever has a one-piece construction with at least a pair of cams for actuation of sensitive switches (microswitches) and forms a pivot body from which the lever arm of the switch lever is mounted and also is provided with a guide for receiving an indexing means, for example, a ball detent for releasably positioning the lever in one of the selected positions thereof.

A ski brake apparatus is provided which comprises two brake arms each mounted on one side of the ski and arranged to swing under the action of a spring force into a braking position in which the brake arm partly extends under the bottom side of the ski. Each brake arm and the associated spring is integrally formed from the same spring material. Each brake arm comprises a prolongation perpendicularly bent-off and mounted onto the ski to form the swing axis. This axis is oriented parallel with the upper side and transverse to the longitudinal direction of the ski. The end of the prolongation opposite to the brake arm is bent to form a spring bracket. The end of this spring bracket is bent parallel to the swing axis and separated from this axis in longitudinal direction of the ski. The spring bracket acts as the operation means of the brake apparatus to hold and to release the brake arm in the stand-by position and in the brake position, respectively, and is oriented upwardly from the upper side of the ski when the brake arm is in its brake position.

A ski attachment is provided with a vertically directed slot-like opening bounded by two parts which project upwards from its base plate. As the ski attachment can be fixed to a ski in easily detachable manner, it can serve in the detached state as a clip for holding together a pair of skis by introducing the skis into the slot-like opening. The skis of one pair then engage with one another within the attachment by their contact surfaces.

A body has a base plate having an adhesive connection to a ski and especially with its scoop-like tip region, the adhesive appearing between an additional attachment plate and the ski. Between the attachment plate and the base plate of the body there is provided an elastic connection which is formed by a tongue-like part produced at the base plate of the body, this tongue-like part being resiliently bendable.

A ski brake mechanism comprising at least one laterally positioned brake arm for the ski which can be rocked into a position below the plane of the running surface of the ski and an actuation portion or component which can be depressed by the ski boot. The brake arm and actuation portion are essentially formed as one-piece from a common spring wire. The brake arm essentially consists of a loop-shaped section of the spring wire, the two legs of which are mounted upon the ski by means of two transversely extending mutually spaced pivot shafts or axes. The actuation portion essentially comprises a wire section merging in a lever-like fashion at one of the two legs.

Physical training apparatus for holding a person's feet while the person lies supine on a floor with his or her feet facing a closed door, includes a generally trapezoidally shaped foot bar support member which has a base portion with a planar bottom surface facing toward the floor. The support member also has a first surface which extends normal to the floor and faces toward the person, and a second surface which is inclined upwardly from the base portion toward the first surface and which faces toward the door. An extension member extends from the base portion toward the door to pass through an opening between the door and the floor, and to engage the door so as to prevent the bar support member from moving away from the door. A wedge-like space is thereby formed between the bar support member and the door, and a locking wedge is provided for insertion in the wedge-like space to fix the bar support member against movement toward the door. Accordingly, the apparatus dispenses with the need for another person to hold the feet of the person when performing sit-ups.
