Abstract
A bicycle wheel has a plurality of spokes arranged between a continuous profiled rim and a hub (5). At least one covering disk (6) is releasably secured to the wheel in order to provide it with a lateral cover. In order to obtain an easy to release and aerodynamically optimum cover, at least one continuous snapped groove (7) into which the covering disk can snap-in is shaped in the side of the rim profile.
Claims18
A wheel (1) for a bicycle (2) having a plurality of spokes (3) arranged between a circumferential rim (4) and a hub (5), having a first and a second disk cover (6) removably mounted thereto to cover the wheel laterally, said rim (4) being laterally provided with first and second circumferential catch grooves (7;7') for the respective disk cover (6) to be inserted in said groove;
- said wheel further including a rim side wall (20), an inclined rim side wall (20'), and a spoke hole side (22), said first catch groove (7) being circumferentially located in the section between said rim side wall (20) and said spoke hole side (22), and said second catch groove (7') being circumferentially located in the section between said inclined rim side wall (20') and said spoke hole side (22);
- said catch grooves (7,7') holding in place said respective disk cover (6) with an edge means (11) inserted under tension therein;
- and
- said catch groove (7') assigned to said inclined rim side wall (20'), is inclined outward at an angle (63) in relation to said catch groove (7) of said rim side wall (20).
In a wheel (1) for a bicycle (2)
- a circumferential rim (4) having an outwardly facing bed for receipt of a tire, two oppositely disposed sidewalls and an inner wall opposite to said bed, said inner wall being equipped with a plurality of spoke holes,
- a hub (5) centrally disposed relative to said rim and equipped with a plurality of spoke holes, a plurality of spokes (3) extending between said rim and hub and being secured in said rim holes and hub holes, said hub, spokes and rim defining said wheel and with said wheel having sides,
- at least one catch groove (7) extending circumferentially in said rim inner wall adjacent said spoke holes and being open in the direction of said hub,
- a disk cover (6) covering one wheel side and having a circumferential edge means (11) received in said groove, said edge means exerting an outwardly directed tension;
- said disk cover (6) consisting of an essentially circular hoop (11) and a cover (12) stretched over said hoop, an access opening (24) being provided in said disk cover (6) in the vicinity of a valve (25) into which an expanding means (26, 32, 34) is incorporated at least for expanding said hoop (11), said hoop having a gap (27), and said expanding means being movably interlocked with the free ends (28, 29) of said hoop (11) which confine said gap, said free ends (28, 29) are essentially bent inward in a radial direction and away from each other, and said expanding means (26, 32, 34) consists of an expanding wedge (34) slidingly arranged on said free ends.
In a wheel (1) for a bicycle (2) having a plurality of spokes (3) arranged between a circumferential rim (4) and a hub (5), having at least one disk cover (6) removably mounted thereto to cover the wheel laterally, the improvement comprising the rim (4) being laterally provided with at least one circumferential catch groove 97) for the disk cover (6) to be inserted in said groove, said disk cover (6) consists of an essentially circular hoop (11) and a stretchable cover (12) over said hoop, said hoop is completely closed and is provided with an access dent (45) facing away from said catch groove (7) at least at one point.
In a wheel (1) for a bicycle (2)
- a circumferential rim (4) having an outwardly facing bed for receipt of a tire, two oppositely disposed sidewalls and an inner wall opposite to said bed, said inner wall being equipped with a plurality of spoke holes,
- a hub (5) centrally disposed relative to said rim and equipped with a plurality of spoke holes, a plurality of spokes (3) extending between said rim and hub and being secured in said rim holes and hub holes, said hub, spokes and rim defining said wheel and with said wheel having sides,
- at least one catch groove (7) extending circumferentially in said rim inner wall adjacent said spoke holes and being open in the direction of said hub,
- a disk cover (6) covering one wheel side and having a circumferential edge means (11) received in said groove, said edge means exerting an outwardly directed tension;
- said rim (4) has a beveled joint (69) defined by faces (72, 73) with said faces being parallel with the plane of the rim joint;
- and
- a joint plane (76) extends across said rim 4 between said rim side walls (20, 20') and said plane meets the circumference (31) at an acute angle.
