摘要:
Provided is a vehicle speed control device with respect to which the speed at which a centrifugal brake operates can be easily changed from the outside without disassembling the device. A brake drum 11 is fixed to a vehicle body 101a. A brake shoe 23 rotates around a rotary shaft 20 of the wheel 101c, and reduces the rotation speed of the wheel 101c as a result of coming into contact with an inner circumferential side face of the brake drum 11. A spring 24 prevents contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c is lower than or equal to a predetermined speed, and permits contact between the brake drum 11 and the brake shoe 23 when the rotation speed of the wheel 101c exceeds the predetermined speed. A position change mechanism 25 is installed within the brake drum 11, and changes the position of an end of the spring 24 on one end side. A transmission mechanism 26 transmits a force that is input by an external operation to the position change mechanism 25 and drives the position change mechanism.

Self-propelling trolley assembly (100), comprising a battery (156); at least one wheel (111,112) which is driven by an electric motor (151,152;1), which electric motor is powered by said battery; a rotation position or velocity sensor (9) arranged to sense a rotation position or rotation velocity of at least one trolley wheel (111,112); a user interface (153); and a control unit (150) arranged to regulate the electric motor based upon input from said user interface so as to affect a rotation of said wheel according to particular drive patterns. The invention is characterised in that the control unit is arranged to implement at least a feedback assisted propulsion drive pattern, based upon information read from said position or velocity sensor; a free-wheeling drive pattern; and a rocking drive pattern, in that all of said drive patterns are implemented using different drive voltage patterns to said electric motor, and in that the electric motor is of a type in which the stator (2) comprises a number of stator (2) poles (7) which is not an integer multiple of a corresponding number of rotor (3) poles and in which the stator poles are subdivided into at least three magnetically and electrically identical subsets (8) that are mounted one after the other around the angular direction of the electric motor.

The invention provides a theft-inhibiting carrier which includes a body 12 having a chassis 16 on which three wheels 18, 20 and 22 are mounted. The carrier 10 includes theft deterrent means 12. The theft deterrent means is configured, when activated, to dismount the wheels 20, 22 from their respective axles 44 but to retain them connected to the chassis 16 by an elongate flexible tether to impede the movement of the carrier. Two containers 60, 62 are provided and contain chemicals which are fed via pistons 68 to a mixing device 76 and into a valuables receiving chamber in which they foam and set thereby encasing valuables contained therein. A pair of arms 88 are pivotally displaced from a retracted position to an extended position in which they protrude from the containers 60, 62. Sharpened teeth 94 are provided on the arms to further inhibit displacement of the carrier.

The invention relates to a hand-moveable transport trolley (1) which can be stacked along with other such trolleys, comprising a chassis (3), a loading platform (7), two struts which are disposed on the rear side (4) of the chassis (3) and which are directed upwards, bearing a sliding device (14), whereby a braking device (16), which can be influenced by the sliding device (14) and which is active when the transport trolley is not in use, is provided, comprising two brake rods (17) which are disposed in said struts (13) and which are provided with a brake shoe (18) on the lower end thereof which respectively acts upon a rear wheel (9) and whereby a respective brake triggering device (20) is provided underneath the chassis (3) close to each rear wheel (9) and introduced into a wheel fork, and a trigger part (25), which is respectively fitted with an active surface (26,) is disposed on the chassis (3). When two transport trolleys are stacked together, the trigger parts (25) with the aid of the active surface (26) thereof are used to deviate the two brake triggering devices (20) of the previous transport trolley (1). The invention is characterized in that each brake triggering device (20) is connected to a brake rod (17) or brake shoe (18) and guided from the outside into a wheel fork (10). The invention is further characterized in that the active surface (26) of each trigger part (25) is arranged below the underside (6) of the chassis (3).

An anti-theft vehicle system (10) for a vehicle wheel (12) having a rotational axis includes at least one inhibitor (24) disposed within the vehicle wheel to selectively engage and disengage the vehicle wheel to resist and allow rotational movement of the vehicle wheel about its rotational axis. The anti-theft vehicle system (10) also includes rotatable structure disposed within the vehicle wheel and cooperating with the at least one inhibitor for moving the at least one inhibitor between an engaged position and a disengaged position with respect to the vehicle wheel. The anti-theft vehicle system further includes a receiver (69) operatively associated with the vehicle wheel to receive a predetermined signal to activate the rotatable structure to move the at least one inhibitor between the engaged position and disengaged position.

Die Erfindung hat eine Sicherungsvorrichtung bei mobilen, mit Laufrädern oder Laufketten versehenen Fahrtreppenreinigungsmaschinen, die bei stehender Fahrtreppe von Treppenstufe zu Treppenstufe versetzbar sind, um diese nacheinander einem Reinigungszyklus zu unter werfen, zum Gegenstand. Die Sicherungsvorrichtung gegen Absturz besteht aus einer an der Reinigungsmaschine angebrachten Bremsvorrichtung (3), die einen Bremsschuhs (5) aufweist, der von einer Gleitkufe (8) gesteuert automatisch in Wirkstellung gebracht wird und eine weitere Bewegung der Reinigungsmaschine auf der Treppenstufe (4) stoppt, wenn sich die Reinigungsmaschine gegen die Kante der Treppenstufe (4) über ein vorgegebenes Maß bewegt, indem die Gleitkufe (8) über die Kante der Treppenstufe (4) abgleitet, so daß der Bremsschuh (5) in formschlüssigen und/oder kraftschlüssigen, eine weitere Bewegung gegen die Treppenkante stoppenden Kontakt mit der Treppenstufe (4) kommt.

A hand-detecting brake system for baby stroller is equipped on a stroller frame (1), including a handle holder (2), a brake mechanism (4), an electric motor (5), and a battery (6). The handle holder (2) is connected to one end of the stroller frame equipped with a hand-detecting device (3) for creating a signal when user's hand being held or touched on the handle holder (2). The brake mechanism (4) is operatively mounted on one side of a first wheel (18) of the stroller frame for braking and un-braking the first wheel (18). The electric motor (5) is capable of driving the brake mechanism (4) to brake the first wheel (18) when being received the signal from the hand-detecting device (3), and un-brake the first wheel (18) when the signal from the hand-detecting device (3)being disappeared. The battery (6) electrically connected to the hand-detecting device (3) and the electric motor (5) for supplying needed power thereto.

Die Erfindung betrifft eine fahrbare Vorrichtung mit Rädern (20) und mit einer Handhabe (10), an welcher die Vorrichtung von einer Bedienperson manuell verfahrbar ist. Des Weiteren ist wenigstens eine Bremse (21) vorgesehen, welche einen Freigabezustand besitzt, in welchem die Räder (20) um ihre Achse rotationsbeweglich sind und die Vorrichtung verfahrbar ist und welche über einen Sperrzustand verfügt, in welchem die Rotationsbewegung wenigstens eines der Räder (20) gebremst wird und die Vorrichtung nicht mehr verfahrbar ist. Die Erfindung schlägt nun vor, dass die Bremse (21) bzw. Bremsen sich normalerweise in ihrem Sperrzustand befinden, dass aber an der Handhabe (10) ein federbelastetes (13) Betätigungselement (11) vorgesehen ist, welches bei Betätigung durch eine Bedienperson unter Zwischenschaltung eines Übertragungsmittels (30) die Bremse (21) bzw. die Bremsen in den Freigabezustand überführt wodurch die Vorrichtung verfahrbar ist ( Fig. 2 ).
