摘要:
A rear axle for motorcycles comprises a torque or link bar (40) and a fork (10) that is elastically suspended to the frame (100) and encloses a Cardan drive shaft (30) in an arm (17) thereof which is joined to a housing (14) of the bevel gear pair (22, 23) driving the rear wheel (50). At both end portions of the torque bar (40) there are provided a first pivot (43) for connection to the frame (100) above the attachment pivot of the fork (10), and a second pivot (45) for connection to a floating member (20), respectively, in which said floating member is in turn supported within said housing (14) for the bevel gear pair (22, 23) by a further pivot (27) firmly joined to the hub (52) of the wheel (50). The axis (F) of said second pivot (45) is parallel to the axis of rotation (R) of the rear wheel (50).
摘要:
Shock-damping buffer arrangement for vehicles on loading stations comprising one or more cylindrical bumpers (10;110) pivoted according to a horizontal axis (X) on a rigid frame (1;100;200), in which:
the bumpers (10;110;210) are made of a material of approximately 50 Shore D or greater hardness; between at least one of the bumpers and the frame there are provided elastically deformable means (16,17;161,162,163,164;214) which, in the event of a shock, cause the bumpers to temporarily displace with respect to the frame in a direction (A) that is substantially perpendicular to the pivoting axis of the same bumpers.
摘要:
In a package of frozen liquid which is closed by a sealing film (30), the bottom wall (12) of the container (10) has a lower thickness than the lateral walls (14, 16, 18, 20) and is provided with at least two relieves (22, 24) separated by at least one recess (26) parallel thereto.
摘要:
The invention relates to a motorcycling glove wherein two or more fingers are connected together with the use of strips of leather or equivalent system. A rotation of the glove fingers with respect to the hand fingers can be avoided in case of fall and the seamed joints along the fingers are prevented from breaking.
摘要:
The upper part (3) of the shell (1), manufactured as one piece from polymer material, of a footwear is divided on the front into two pairs of flaps (6A, 7A; 6B, 7B) by a longitudinal separating line (5) and by a transverse slit provided opposite the user's heel. Two removable inserts (11, 12) are provided, which may even be manufactured using a type of polymer material different from that of the shell (1), have parts (13, 15; 14, 16) which are designed to interfere both with the outer surface and with the inner surface of the said flaps (6A, 7A; 6B, 7B) and also have interconnecting parts (17, 18) which are designed to be retained by the two sections (8A, 8B) of the transverse slit. USE: Ski boots and skating boots, safety footwear and the like. ADVANTAGES: No infiltration (e.g. of water and snow) into the boot; more efficient manufacturing of the boot.
摘要:
Structure, associated with a motorcycle boot, which is designed to restrict, in the event of accidental falls followed by contact at high speed with the ground, the movements of the leg-piece (12) of the boot with respect to the axis of a heel-piece (14). First hinging means (16) which are angularly movable in a substantially unlimited manner and axially movable between two stopping means and second hinging means (18) which are movable only angularly in a restricted manner. Alternatively, the first and second hinging means can be formed by elements (176, 178) made of elastomeric materials.
摘要:
The invention refers to a so-called fan-heater unit, adapted to be included in an apparatus such as a fan-assisted or forced-convection food cooking oven for catering or commercial applications. The unit comprises at least a tangential-type fan (32) mounted with its shaft (42) extending vertically and supported at both its ends by rolling-type journal bearings (44, 46). A main feature of the invention is that the inner ring (461) of at least a bearing (46) is mounted with a diametral clearance (480) on a corresponding end portion (422) of the shaft (42), elastic means (468) being provided which, preferably formed by at least a helical spring, are adapted to exert an axial thrust on said inner ring (461). Said axial thrust generates a friction torque capable of inducing said ring to rotate with said shaft. Advantages: Elimination of the negative effects due to instant thermal-expansion differences between the fan and the structure on which it is mounted.
