Description
- (a) Field of the Invention
- The invention relates to a wheel body and a bearing of in-line skate, and more particularly, to a wheel body and a bearing of in-line skate capable of preventing locking of the wheel body resulted from twisting of alien objects intruded into the spacing between the wheel body and the bearing, as well as locating the bearing with evenly dispersed stress without losing grease and causing deformation thereof.
- (b) Description of the Prior Art
- FIGS. 1, 2,3 and 4 show a conventional elevational view of a prior art disposed at a bottom frame of an in-line skate, a conventional exploded sectional view of a prior art, and a conventional sectional view and a conventional side view of a bearing in a prior art. Wherein, a
wheel 1 is disposed withaxletree 10 for reducing production cost and weight, at the outer edge of arecess 12 at the center of thewheel 1 for fitting abearing 13 is provided with aspacing 11, and therecesses 12 at the sides are for fitting thebearings 13. In order to increase the supporting ability thereof, between the twobearings 13 is further provided with acentral sleeve 14, and from the center extending outward is provided withcaps 15 connected with thecentral sleeve 14. The entire body is then placed into the center of a bottom frame havingaxis openings 20, so as to fasten the body through the center thereof by means ofscrews 21 and screw couplers 22 (as shown in FIG. 3). However, the defective design of the prior art due to the exposedspacing 11 easily incurs twisting of alien objects such as dust, ropes, stones and steel wires that lock the wheel body, thus resulting in falling of the skater. Therefore, the prior art is clearly dangerous and unsafe. In addition,rollers 134 provided at the center of thebearings 13 are loose as having no containment device, and therefore the grease therein for lubricating is easily lost, and hence shortening the lifespan thereof. Also, for that therollers 134 are not located at fixed positions, thebearings 13 may consequently operate unsmoothly such that stress thereof is not evenly dispersed and further bringing deformation or even locking thereof. On top of that, the gap between the twobearings 13 is rather small that alien objects such as hair or thin ropes may easily get caught, leading to locking as well. All the aforesaid shortcomings have long since perplexed industrialists and consumers, and therefore, it is a vital task and also the object of the invention as how to provide a wheel body and a bearing in-line skate having enhanced practical values. - An object of the invention is to provide a wheel body and a bearing of in-line skate, so as to solve the twisting of alien objects, the loss of grease, the unsteady positions of the rollers and the deformation resulted from unevenly dispersed stress as in the prior art. To accomplish the aforesaid object, the structure a in accordance with the invention comprises a wheel cover provided at a spacing, bearings consisted of outer shells having a lengthened central axis, and a containment ring having concaves and an outer cover for holding the rollers. As a result, locking caused by alien objects being twisted into the spacing is prevented, the rollers are positioned for smooth operations, and the stress thereof is evenly dispersed without bringing deformation thereof.
- FIG. 1 shows a conventional elevational view of the prior art disposed at a bottom frame of an in-line skate.
- FIG. 2 shows a conventional exploded view of a prior art.
- FIG. 3 shows a conventional sectional view of a prior art.
- FIG. 4 shows a conventional side view of a bearing according to the prior art.
- FIG. 5 shows an exploded elevational view according to the invention and a side view of the bearing thereof.
- FIG. 6 shows an elevational view according to the invention.
- FIG. 7 shows a sectional view according to the invention.
- FIGS. 5, 6 and7 show an exploded elevational view and a side view of the bearing thereof, an elevational view, and a sectional view in accordance with the invention, respectively. Wherein, at the exterior thereof is provided with a
recess 12 for fitting abearing 13 at the sides of anaxletree 10 of thewheel body 1, respectively, and at the outer edge of eachrecess 12 is provided with aspacing 11 for reducing production material and weight. In order to prevent intrusions of alien objects into thespacing 11, one side of theaxletree 10 is sealed and the other side thereof is in communication with opening air. Also,fitting openings 111 are disposed at the partition of thespacing 11 for fitting a sealingaxletree cover 112, andfitting axes 113 are disposed at corresponding positions of theaxletree cover 112 for fitting into thefitting openings 111 to close the opening thereof, such that twisting of alien objects namely dust, ropes, stones or steel wires into thewheel body 1 and theaxletree 10 is prevented during high speed operations, thereby avoiding accidental falls and dangers resulted from sudden locking thereof. - The
bearing 13 provided at therecesses 12 at the sides from the center of theaxletree 10 further comprises anouter shell 131 having a lengthenedcentral axis 133,rollers 134, acontainment ring 133 withcorresponding concaves 1331, and anouter cover 135. During the assembly of the invention, therollers 134 are placed therein through the opening end of the invention. At the two sides of therollers 134 are provided with thecontainment ring 133 havingcorresponding concaves 1331 for positioning the rollers 134 (as shown in the enlarged views in FIG. 5), such that therollers 134 are positioned within the concaves 1331. Theouter cover 135 then encloses therollers 134 and thecorresponding containment ring 133 at the outer edge of theouter shell 131. Referring to the bottom of FIG. 5 showing a side view of thebearing 13 after the invention is sealed, the aforesaid assembled members are placed into thebottom frame 2 havingaxis openings 20 and further combined into one body by means ofscrews 21 andscrew couplers 22. Because at the two sides from the center of theouter shell 131 of thebearing 13 is provided with a lengthenedcentral axis 132 that offers support and is free of gaps from joining, intrusions of alien objects such as hair or thin ropes causing locking and the resultant falling of the skater are prevented while also maintaining high speed operations of the in-line skate. In addition, therollers 134 in accordance with the invention are positioned by thecorresponding concaves 1331 of thecontainment ring 133, and therefore therollers 134 are perpetually in orientation with theouter shell 131, thus giving even stress thereupon as well as smooth operation, further preventing deformation of thebearing 13 that may lead to locking thereof. Also, the grease held therein is not lost easily, so that the rollers 34 may operate at an optimal lubricated status, thereby lengthening the lifespan thereof. - While this invention has been particularly shown and described with references to preferred embodiments thereof, it will be understood by those skilled in the art that various changes and adaptions may be made therein without departing from the true spirit and scope of the invention as defined by the appended claims.
