Description
- 1 Field of the Invention
- The present invention relates to a roller skate and a wheel assembly for the roller skate.
- 2. Description of the Related Art
- The wheels of a typical roller skate are fixed to an underside of the roller skate, and the user has to wear a pair of shoes (generally sport shoes) before putting the roller skates on. The user cannot walk on rugged surfaces when wearing the roller skates. Thus, the user faces troublesome actions of putting on and taking off of the roller skates when he/she starts or stops skating.
- Taiwan Utility Model Publication No. 339688 issued on Sep. 1, 1998 discloses a roller skate includes a base and a number of wheels that can be pivoted to storage positions in the base such that the user may directly walk through rugged surfaces without troublesome actions of taking off and re-putting on of the roller skates. As can be seen from FIG. 7 of the drawings, the base1 includes two shoulder sections 2 to which the wheel seats 3 may bear against during skating. However, when walking on an inclined surface, one of the wheel seats 3 might be pivoted into the
storage compartment 4 in the base 1. The wheel seats 3 might also be pivoted into thestorage compartments 4 if they impinge objects on the ground. The skater might be injured as a result of losing balance. - The present invention is intended to provide a wheel assembly for a roller skate that mitigates and/or obviates the above problem.
- It is a primary object of the present invention to provide a roller skate having two wheel assemblies that can be moved to the storage positions when not in use and that can be retained in operative statuses when skating.
- A wheel assembly for a roller skate in accordance with the present invention comprises:
- a pivotal seat having a first end secured to a base of the roller skate and a second end;
- a wheel seat having a first end pivotally connected to the second end of the pivotal seat by a pin and a second end;
- a wheel rotatably mounted to the second end of the wheel seat, the wheel seat further including a mounting member;
- a first elastic member having a first end attached to the pivotal seat and a second end attached to the mounting member of the wheel seat for biasing the wheel seat to a storage position in the base;
- a stopping means including a first end mounted to the pin and a second end through which the mounting member is extended, the stopping means further including a stop; and
- a second elastic member mounted around the pin for biasing the stop of the stopping means to a position for releasably engaging with the wheel seat to prevent the wheel seat from moving into the storage position in the base.
- By such arrangement, the wheel seat may be moved into the base when not skating. When skating is required, the wheel seat and the wheel are extended beyond the base, and the stop may prevent the wheel seat from entering the base during skating, thereby preventing potential injury to the skater.
- The present invention also provides a roller skate that comprises:
- a base having at least two compartments, the base further having a corresponding number of shoulders defined in said at least two compartments, respectively;
- a corresponding number of wheel assemblies each of which is mounted in an associated said compartment, each said wheel assembly including:
- a pivotal seat having a first end secured to the base and a second end,
- a wheel seat having a first end pivotally connected to the second end of the pivotal seat by a pin and a second end,
- a wheel rotatably mounted to the second end of the wheel seat, the wheel seat further including a mounting member;
- a first elastic member having a first end attached to the pivotal seat and a second end attached to the mounting member of the wheel seat for biasing the wheel seat into the associated compartment in the base;
- a stopping means including a first end mounted to the pin and a second end through which the mounting member is extended, the stopping means further including a stop; and
- a second elastic member mounted around the pin for biasing the stop of the stopping means to a position for releasably engaging with the wheel seat; and
- an upper mounted on top of the base.
- Each wheel seat is pivotable between an operative position and a storage position in the associated compartment. When each wheel seat is in the operative position, each wheel seat bears against an associated shoulder while the wheel rotatably attached to each wheel seat extends beyond the base for skating. In addition, when each wheel assembly is in the operative position, the stop of each stopping means is engagable with an associated wheel seat to prevent the associated wheel seat from entering the associated compartment.
- Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
- FIG. 1 is an exploded perspective view of a roller skate in accordance with the present invention;
- FIG. 2 is a side view, partially sectioned, of the roller skate in accordance with the present invention, wherein the wheels are in operative positions;
- FIG. 3 is a side view similar to FIG. 2, wherein the roller skate is passing through a decline;
- FIG. 4 is a cross sectional view illustrating operation of a stopping means of the roller skate;
- FIG. 5 is a view similar to FIG. 4, wherein the stopping means is in a status allowing the wheel seat to move to a storage position;
- FIG. 6 is a side view similar to FIG. 2, wherein the wheels are in storage positions; and
- FIG. 7 is a side view, partially sectioned, of a conventional roller skate.
- Referring to FIGS. 1 and 2, a roller skate in accordance with the present invention generally includes a base or sole403 having two
compartments bottom plate 412 mounted to an upper side of thebase 403, twowheel assemblies bottom plate 403, and a stopping means 350. As can be seen from FIG. 2, thecompartment 404 receives thewheel assembly 31, while thecompartment 405 receives thewheel assembly 32. Thebase 403 further includes twoshoulders compartments - A
soft padding plate 413 may be provided on top of thebottom plate 412. An upper 401 is attached to thebase 403 and includes an interior 402 for receiving the foot of the skater, which is conventional and therefore not further described. - The
bottom plate 412 includes a number ofpositioning holes 414. Eachwheel assembly pivotal seat 340 having a first end attached to the underside of thebase 403 by means of extending fasteners (e.g., bolts 415) through associatedpositioning holes 414 in thebottom plate 412, positioning holes 408 in thebase 403, and positioningholes 342 in thepivotal seat 340. Eachpivotal seat 340 further includes a second end to which an end of awheel seat 330 is pivotally connected by means of extending apin 341 through holes 343 in thepivotal seat 340 and holes 333 in thewheel seat 330. The other end of eachwheel seat 330 includes awheel 320 rotatably mounted thereto. An elastic member, e.g., atorsion spring 332 is attached between thepivotal seat 340 and amounting member 331 on thewheel seat 330 for biasing thewheel seat 330 to its storage position in the associatedcompartment - The stopping means350 includes a first end pivotally connected to the pin 341 (by means of extending the
pin 341 through holes 353 in the stoppin, means 350) and a second end with a hole 354 through which themounting member 331 extends. The stopping means 350 further includes astop 351. A further elastic member, e.g., a coil spring 353 is mounted around thepin 341 and attached between the first end of the stopping means 350 and the wheel seat 330 (FIG. 4). - When the
wheel seats 330 are pivoted to extend beyond thebase 403, thewheel seats 330 bear against theshoulders front wheel seat 31 moves away from theshoulder 406 and pivots through an angle until thestop 351 of the stopping means 350 engages with and is thus stopped by thepivotal seat 340, thereby preventing further pivotal movement of thewheel seat 330, as shown in FIG. 4. Thus, thewheel seat 330 will not move into itsstorage compartment 404, i.e., thewheel seat 330 is retained in its operative status for skating to thereby avoid potential injury to the skater. - As can be seen from FIG. 4, the stopping means350 is biased by the
elastic member 352 toward a side of thewheel seat 330 such that thestop 351 may bears against thepivotal seat 340 to prevent movement of thewheel seat 330 into thecompartment 404. Referring to FIG. 5, when not skating, the stopping means 350 may be moved axially away from the side of thewheel seat 330 such that thewheel seat 330 may move into thecompartment 404 under the action of theelastic member 332, as thestop 351 is not on the way of thewheel seat 330 into thecompartment 404. As a result, the wheel seats are moved into the storage positions when not skating, as shown in FIG. 6. Thus, the roller skate can be used as a normal shoe. - According to the above description, it is appreciated that the wheel seats in accordance with the present invention may be received in the compartments in the base when not skating, and the wheel seats are prevented from entering into the compartments when skating, thereby preventing potential injury to the skater.
- Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
