Definitions
- the present invention pertains to roller skates. More particularly, the invention relates to a roller skate which is adapted to assist beginners to learn to skate more easily and safely than on conventional roller skates.
- Conventional roller skates have been available for many years.
- conventional roller skates include four wheels, a pair of which are located at the front end of the skate and the second pair located at the rear end of the skate.
- the skates can be adapted to be attached to normal walking shoes or can be constructed so that the shoe is an integral part of the skate.
- the wheels of the conventional roller skate will turn either in the forward or rearward direction. Because of this ability of the skate to roll in either direction, it is in some instances very difficult for a beginning skater to safely and easily learn to skate. As often occurs, a beginning skater will attempt to stop his forward motion only to begin to roll backwards. Unaccustomed to this motion a beginning skater will lose his balance.
- roller skate which may be used as a training skate for the beginner such that he or she may learn to skate more easily, minimizing the risk of injury. It is desirable, however, that this roller skate be capable of being used in the conventional manner by the more advanced skater. It is also desirable that the skate be adjustable to fit a range of shoe sizes and that it be quickly and easily attached to and released from the shoe or bare foot of the skater.
- a trainer/learner skate in which a ratchet and pawl assembly is attached to at least one wheel of a roller skate thereby restricting the motion of that wheel, and hence the motion of the roller skate, to the forward direction only.
- the ratchet and pawl assembly may be selectively disengaged to allow the roller skate to function in a conventional manner.
- a back stop member is attached to the rear of the roller skate and designed to come into contact with the ground or other support surface when the toe of the skate is raised to a predetermined height.
- the wheels of the roller skate in the present invention are attached to a base plate which is longitudinally adjustable to provide for attachment thereof to a range of shoe sizes.
- the upper portion of the skate is fitted with self-adhering quick release straps which quickly and easily attach either the shoe or the bare foot of the skater to the roller skate.
- the general object of the present invention is to provide a roller skate which will enable a novice skater to learn to skate quickly, easily, and safely.
- a further object of the present invention is to provide a roller skate in which one or more of the wheels may be selectively restricted to forward motion only.
- FIG. 1 is a side elevation of the trainer/learner skate of the present invention
- FIG. 2 is a bottom elevation of the roller skate of the present invention
- FIG. 3 is a fragmentary side elevation showing the manner in which the back stop acts as either a brake or as a means for preventing the skate from tipping;
- FIG. 4 is a cross-section taken along the lines 4--4 in FIG. 2;
- FIG. 5 is a cross-section taken along the lines 5--5 in FIG. 4;
- FIG. 6 is a fragmentary elevation illustrating the ratchet and pawl assembly.
- FIG. 7 is a view similar to FIG. 6 illustrating the ratchet and pawl assembly in the engaged position limiting the rotation of the wheel.
- the roller skate of the present invention includes a base plate 10 that is comprised of a front base plate 12 and a rear base plate 14 which are connected together by adjustment rail 16 by means of nut and bolt assemblies 18.
- Nut and bolt assemblies 18 pass through a hole formed in front base plate 12 and a hole in rear base plate 14 and extend through elongated slots 20 and 22 formed in the adjustment rail 16.
- the skate also includes a shoe-engaging member 24 mounted on the front base plate 12 and a heel-engaging member 26 which is mounted upon rear base plate member 14.
- shoe engaging members 24 and 26 have straps 27 which can be pulled tightly across the shoe or bare foot of the skater to securely attach the shoe or foot to the skate.
- the underside of straps 27 and corresponding outer surface of shoe engaging members 24 and 26 are fitted with self-locking fabric to provide for quick attachment and release of the skate to the shoe or bare foot of the skater.
- Other similar quick release means will be readily apparent to those skilled in the art.
- other principles of the present invention can be incorporated in a roller skate in which the shoe of the skate is an integral part of the roller skate.
- the roller skate of the present invention may also include a conventional front stop member 28 which is mounted at the front end of base plate 12 by any convenient means such as screw 30.
- the roller skate includes a back stop member 32 mounted on the lower surface of rear base plate 14 at the rear end thereof. The function and operation of back stop member 32 will be discussed below.
- the preferred embodiment of the saftey roller skate also includes a pair of rear wheels 34 which are journaled on axle 36 that is mounted in a wheel mounting pedestal 38 that projects downwardly from rear base plate 14.
- a pair of front wheels 40 are journaled upon front axle 42 which is journaled in front wheel pedestal 44.
- each of the front wheels 40 has a ratchet gear 46 mounted on the inner surface 48 of wheels 40 and which rotate with wheels 40.
- a pawl mounting bracket 50 is mounted on front axle 42 between each of the ratchet gears 46 and the front wheel mounting pedestal 44, and extends rearwardly from the axle 42. In operation bracket 50 is prevented from rotating by ears 52 and 54 engaging wheel mounting pedestal 44.
- mounting bracket 50 mounted on one of the front wheels is the mirror image of the other mounting bracket 50 mounted on the other wheel.
- a pawl 56 is pivotally mounted at the rearward end of pawl mounting bracket 50 by any suitable means such as nut and bolt assembly 57, and is of such a length and located in such a manner that it is engageable with ratchet gear 46, as best seen in FIGS. 6 and 7.
- Pawl 56 extends forwardly from its pivot mounting toward ratchet gear 46 and has as its outer end a series of teeth 58 which are adapted to mesh with the teeth of gear 46.
- the teeth 58 are concave to adapt to the perimeter of ratchet gear 46.
- teeth 58 may also be formed in a slightly convex shape without loss of efficacy.
- Bracket 50 includes a stop tab 60 which blocks any rotation of pawl 56 once the teeth 58 have become enmeshed with the teeth on ratchet wheel 46.
- the pawl mounting bracket 50 and pawl 56 may be removed by first removing the wheel next to which the bracket 50 is situated and sliding the bracket off of the axle. The wheel is then replaced. In this event, ratchet gear 46 would remain on wheel 40 although it would serve no function.
- the bracket 50 may also be fitted with cam means to selectively hold pawl 56 in the disengaged position.
- a further aspect of the present invention involves back stop 32 which is mounted by conventional means underneath and at the back of rear base plate 14, extending downwardly from the lower surface of rear base plate 14 toward the support surface 62 upon which the skates would be used.
- the specific distance that back stop 32 extends from base plate 14 can be varied by the dimension of back stop 32, however, in normal use when all four of the skate wheels are on support surface 62, the back stop 32 will be positioned a distance above the support surface.
- the back stop 32 serves at least two functions. First, if the skater were to tip backwards by rotating the whole skate about rear wheels 34, the back stop would engage the support surface and help prevent the skater from falling.
- the back stop can be used by the skater as a braking means by deliberately rotating the skate about rear wheels 34 in a rearward direction so that, as seen in FIG. 3, the back stop 32 will engage the support surface and apply frictional brake pressure to slow or stop the skate.
- the construction of the present invention is such that the ratchet and pawl assembly can be removed, or the pawl selectively held in the disengaged position, so that the skate can be used in a conventional manner.
- An added feature of the invention is that it will be much easier for a skater to skate up an incline since the wheels are free to move in only the forward direction.
- the incorporation of a back stop member provides a roller skate that is safer for a beginning skater because the skater will be less likely to fall backwards while using the roller skate.
- the incorporation of the quick release straps enable the skates to be quickly attached to and removed from the shoe or bare foot of the skater.
