摘要:
A device for adjusting the relative angular position of two mutually articulated structures comprising a first and a second element (5, 6) respectively connected to said structures, that rotate mutually around the axis of articulation of said structures and that define two chambers between them whose volume varies inversely as a result of the relative rotation of said elements. Said variable-volume chambers are connected together by conduits (3). The chambers and the conduits are filled with a fluid that flows from one chamber to the other through the conduits as a result of the relative rotation of the two elements around their axis of articulation. Valves are provided for interrupting communication through said conduits (3), so as to prevent the passage of fluid from one chamber to the other and consequently lock the two elements in any relative position to which they have been adjusted.

A carrier for a motor-vehicle roof comprises a bar (1) provided at its ends with two supporting legs (7) which constitute two outer clamping jaws which are for engaging two longitudinal guides (8) secured to the motor-vehicle roof. An inner jaw (10) is pivotally connected to each outer jaw (7) and is moveable between an opened position and a closed clamping position. The bar (1) is provided with a screw (3) for actuating synchronous and symmetrical movements along the bar (1) of two actuating members (4) which are adapted to cause a movement of the two outer jaws (7) towards each other at a first time, until the outer jaws (7) engage the outer lateral surfaces of the two longitudinal guides (8), whereupon at a second time the two inner jaws are caused to close onto the longitudinal guides (8), so that clamping of the bar (1) on the longitudinal guides (8) is obtained.

A bicycle-carrying device (6) is mounted on the tow hitch (2) of a motor-vehicle by means of a coupling device (10) which includes a sleeve (11) rigidly connected to the structure (5) of the bicycle-carrying device (6). The sleeve (11) has an inner surface including an engaging portion (113) which is placed over the ball (4) of the tow hitch (2). A clamping ring (12) is pre-arranged below the ball (4) and is tightened on the sleeve (11) to lock the sleeve in the engaging condition on the ball (4). In the tightened condition of the clamping ring (12) on the sleeve (11), a locking member (13) arranged within the clamping ring (12) is axially compressed between the clamping ring (12) and the ball (4), so that in this condition the sleeve (11) is locked on the ball (4).
摘要:
A bicycle-carrying device for motor-vehicles comprises a frame (4) which is mounted on the rear part of a motor-vehicle and is provided with receptacles (12, 13) for supporting one or more bicycles in vertical planes parallel to the longitudinal direction of the motor-vehicle, without hiding from view substantial portions of the rear plate and/or the rear lights of the motor-vehicle.

An equipment carrier for mounting onto a rear component of a vehicle structure, such as a vehicle trunk lid or door, comprises a frame (22) having lower engagement elements (40) engageable with a lower area of the vehicle component, a structure connected to the frame (22) for carrying one or more items of equipment, at least one vehicle engaging member (24), connected to the frame, for engaging the vehicle component at a position above said lower area, a strap member (26) having upper engagement elements (104) for engagement with an upper area of the vehicle component, and at least one support connected to the frame, provided with a strap engaging and tensioning mechanism (110), which is engaged by the strap member (26) and can be controlled for tensioning the strap member in order to tighten the upper and lower engagement elements onto the upper and lower areas of the vehicle component.
摘要:
A self-centering roof rack system for transporting bicycles and other sporting goods on a motor vehicle. The rack includes a transverse bar mounted on the roof (1) and supported by upright members (8',8") at each end. The upright members (8',8") are simultaneously moveable by rotation of a knob (62) at one end of the rack by means of rotation of a threaded shaft (63) which has right hand threads on one end (64) and left hand threads on the other (64'). The upright members (8',8") are provided with either a pivoting or sliding mechanism that causes a floating hook (70,70") adapted to grip a motor vehicle rip edge (1a), the hook (70,70") being caused to move upwardly and outwardly to firmly engage the roof as the uprights (8',8") are moved toward each other.
摘要:
A bicycle simulator ( 1 ) is basically constituted by a bicycle pre-arranged for static or pseudo-static use. The bicycle comprises front and rear supports (13, 14) for resting on the floor ( 12) that simulate the contact of the wheels of a normal bicycle on the road. The two supports are preferably constituted by a front supporting wheel (1 3) and by a rear supporting wheel ( 14) that rest on the floor and support in a freely rotatable way the respective wheel axles (3, 1 1). Rotatably mounted within at least the front supporting wheel is a flywheel (Fl, F2). The front flywheel (F l ) is set in rotation by a respective electric motor (M) or by a transmission driven by the pedals, for creating a stabilizing gyroscopic effect, which enables the user to maintain his balance when pedalling with the bicycle stationary, resting on the floor via the supporting wheels in a static condition. The crank axle is connected to a driven member, which is independent of said front support (13) and of said rear support (14) and is constituted by a rear flywheel or even by the front flywheel itself.
