Definitions

  • the present invention relates to a roller skate, and particularly to a braking arrangement for a roller skate.
  • the invention is expecially useful with respect to the in-line skates commonly called “Roller Blades" which includes a single line of wheels, and therefore the invention is described below particularly with respect to this application.
  • Roller skates of the in-line skates type have recently become very popular particularly among children.
  • one of the drawbacks of the roller blades now in wide use is the difficulty in braking.
  • One popular model includes a fixed braking element at the rear of the roller skates engageable with the ground when the user pivots the rear end of the roller skates downwardly about the user's heel.
  • a braking arrangement puts the user in a very unstable position during braking since the upper end of the roller skate moves upwardly out of contact with the ground. As a result, the skater may easily lose balance or control.
  • An object of the present invention is to provide a roller skate in general, and particularly of the in-line skate type, with a braking arrangement which enables the user to brake the roller skate in a better manner than that described above.
  • a roller skate comprising a base member to be fixed to the bottom of a shoe to receive a user's foot; and a wheel carrier mounted to the base member, and in turn rotatably mounting a plurality of wheels; characterized in that the wheel carrier is pivotally mounted to the base member about a horizontal pivotal axis, and in that the base member further mounts a brake member effective to brake the roller skate.
  • the invention is particularly applicable to the roller blade type of roller skate wherein the wheel carrier carries a single line of wheels.
  • the brake member is a brake shoe engageable with at least one of the wheels of the wheel carrier when the base member is pivoted with respect to the wheel carrier.
  • the brake member is a brake shoe engageable with a pair of brake discs secured to opposite sides of at least one of the wheels of the wheel carrier when the base member is pivoted with respect to the wheel carrier.
  • the brake member includes a brake element carried by the base member rearwardly of the plurality of wheels to engage the ground when the base member is pivoted with respect to the wheel carrier.
  • a roller skate particularly of the in-line skate type, constructed in accordance with the foregoing features permits the user to effect a braking action by merely shifting weight from the sole of the foot to the heel of the foot. When doing so, the wheels remain in contact with the ground so that the user maintains a more stable position during the braking action, thereby decreasing the chances of falling or otherwise losing control.
  • Such a roller skate also requires a minimum change in the construction and normal use of the present roller skates particularly of the roller blade type.
  • Fig. 1 is a three-dimensional view illustrating a shoe having attached to it one form of roller skate constructed in accordance with the present invention
  • Fig. 2 is a side elevational view of the roller skate of Fig. 1 ;
  • Fig. 3 is a view corresponding to that of Fig. 2 but with parts broken away to show internal structure;
  • Fig. 4 is a view corresponding to that of Fig. 3 but showing the positions of the parts during a braking action
  • Fig. 5 is a sectional view along line V—V of Fig. 3 during the normal use of the roller skate;
  • Fig. 6 is a view corresponding to that of Fig. 5 but showing the positions of the parts during a braking action
  • Fig. 7 is a sectional view along line VII—VII of Fig. 3;
  • Fig. 8 is a three-dimensional view illustrating a modification in the construction of the roller skate of Figs. 1-6 and constituting a second embodiment of the invention
  • Fig. 9 is a sectional view along line IX—IX of Fig. 8.
  • Fig. 10 is a view similar to that of Fig. 8 but illustrating a third embodiment of the invention.
  • the illustrated roller skate is of the in-line skate type; that is, it includes a single line of wheels W--W., of which wheel W- is the frontmost one, and wheel W- is the rearmost one.
  • the roller skate 2 is attached to a shoe 4 to be worn by the user.
  • the attachment is in a permanent manner (e.g., by rivets, welding, etc.) as is presently the common practice with respect to roller skates of the roller blade type, but it is contemplated that the attachment could be in a removable manner (e.g., by a clamp) to enable the roller skate also to be used along with conventional shoes.
  • the structure of the roller skate 2 is more particularly seen in Figs. 2-7. It includes three main components, namely: a base member 6 for attachment of the roller skate to the shoe 4; a wheel carrier 8 carrying the line of four wheels W--W 4 ; and a brake shoe 10 for braking the roller skates when desired by the user.
  • the base member 6 comprises two longitudinally extending bars 11, 12 connected together in parallel spaced relationship at the front ends by a sole plate 13, and at the rear ends by a heel plate 14.
  • Sole plate 13 is attached to the sole of the shoe 4 in any suitable manner, e.g., by rivets (not shown); and heel plate 14 is similarly attached to the heel of the shoe.
  • the heel plate 14 is wider than the sole plate 13 so that it extends laterally on opposite sides of the base member 6.
  • the heel plate 14 is also at a slightly higher elevation than the sole plate 13, by the section 15 of plates 11 and 12 of the base member.
  • Such a construction stably supports the user's weight. It also distributes more of the user's weight to the front end of the roller skate 2 during normal use.
  • the lower surfaces of the two bars 11, 12 of the base member 6 are formed with cutouts 16, 17 (Figs. 2-4) for accommodating the two intermediate wheels W_, W ⁇ of the wheel carrier 8.
  • the wheel carrier 8 is pivotally mounted to the base member 6 by a pivot pin 20 at the rear end of the wheel carrier, between the two rearmost wheels W.., W..
  • Wheel carrier 8 also incudes a pair of bars 21 , 22 secured in parallel spaced relationship by a spacer plate 23 secured across the front ends of the two bars, and by pins 24 secured between the two bars and serving as rotary axes for the wheels W..-W..
  • Spacer plate 23 engages the front undersurfaces of the two bars 11, 12 of base memebr 6 in the normal, non-pivoted position of that member with respect to to the wheel carrier 8.
  • the overall length of the wheel carrier 8 is greater than that of the base member 6, such that the frontmost wheel W 1 projects forwardly of the front end of the base member 6, and the rearmost wheel W. projects rearwardly past the rear end of the base member.
  • the four wheels W--W. are rotatably supported on pins 24 between the two bars 21, 22 of the wheel carrier 8.
  • the spacing between wheels W 1 and W ⁇ is equal to that between wheels 3 and ., whereas the spacing between wheels W_ and 3 is slightly larger than the other two wheel spacings.
  • the wheel carrier 8, pivotal along pivotal axis 20 to the base member 6, is normally urged against the base member by a coil spring 25 secured between the front end of the wheel carrier centrally of its bars 21, 22, and the front end of the base member 6 centrally of its bars 11, 12.
  • Wheel carrier 8, however, is releasably retained in its normal position, as illustrated in Figs. 2 and 3, by a releasable retainer device, generally designated 30, best seen in Figs. 5 and 6.
  • Releasable retainer device 30 includes a spacer tube 31 extending between the bars 11, 12 of the base member 6.
  • Tube 31 houses a pair of balls 32, 33 which are spring-urged outwardly by a coil spring 34 so as to be releasably received within recesses or openings 35, 36 formed in the two bars 21 , 22 of the wheel carrier 8 in the normal (non-pivoted) position of the wheel carrier.
  • balls 32, 22 unseat from their openings 35, 36 to permit the pivotal movement.
  • These spring-urged balls also engage the sides of bars 11, 12 to self-center the wheel carrier 8 during this pivotal movement.
  • the previously-mentioned brake shoe 10 is pivotally mounted at the rear end of base member 6 along piotal axis 40.
  • Brake shoe 10 is of a length to overlie only the two rearmost wheels W 3 , W..
  • the underside of brake shoe 10 is formed with two curved recesses 41, 42 of complementary curvature as the outer surfaces of wheels W_, W., respectively, for engagement therewith.
  • Brake shoe 10 is preferably also formed with a longitudinal groove 43 extending for its complete length including the curved recesses 41 , 42 engageable with the outer side surfaces of wheels W,, W. during the braking action.
  • Brake shoe 10 is further formed with a slot 44 accommodating pivot pin 20 of the wheel carrier 8. Slot 44 is slightly elongated to permit some linear movement, as well as pivotal movement, of the.brake shoe with respect to pin 20 during the braking action.
  • the illustrated roller skate operates in the following manner:
  • the user shifts his or her weight to the heel plate 14 of the base member 6.
  • the center of the heel plate 14 is rearwardly of the pivotal axis 20 of the wheel carrier 8, so that this shifting of the user's weight to the heel will apply a force tending to pivot the base member 6 clockwise about pivotal axis 20, that is, to the open position wherein the front end of the base member 6 rises above the front spacer plate 23 of the wheel carrier 8, thereby expanding spring 25 as shown in Fig. 4.
  • pivotal axis 40 of the brake shoe 10 is rearwardly of pivotal axis 20 of the base member 6, this pivotal movement of the base member will bring brake shoe 10, particularly its curved undersurfaces 41, 42, downwardly against the two wheels W-. and W..
  • the brake shoe 10 thus brakes the rotation of the two rear wheels W 3 , W., of the roller skate 2.
  • this braking action can be easily effected by the user by merely shifting the user's weight to the heel. It will also be appreciated that when this braking action is effected, the base member 6 pivots to its open position (Fig. 6) with respect to the wheel carrier 8, so that the wheels of the wheel carrier remain in contact with the ground, thereby stably supporting the user. Whenever the user wishes to terminate the braking action, the user merely shifts the weight slightly forwardly so that the weight is applied forwardly of the piotal axis 20, which will permit the base member 6 to pivot back to its normal position, thereby releasing the brake.
  • roller skate illustrated in Figs. 8 and 9 is similar to that of Figs. 1-7, and therefore the same reference numerals have been applied to the corresponding parts to facilitate understanding.
  • a pair of brake discs 51, 52 are secured to opposite sides of the rear wheel W. and are engaged by the brake shoe 55 which is configured with side extensions 56, 57 to engage the discs.
  • Such an arrangement relieves the wheels from the wear and tear caused by the braking action, and subjects the braking discs 51 , 52 to such wear and tear.
  • These discs can be constructed to better withstand such wear and tear and also to be replaced whenever necessary.
  • roller skate illustrated in Figs. 8 and 9 is constructed and operates in the same manner as described above with respect to Figs. 1-7.
  • Fig. 10 illustrates a further embodiment wherein the brake member is not engageable with the wheels (Figs. 1-7) or brake discs secured to the wheels (Figs. 8 and 9), but rather is engageable with the ground, similar to the brake member commonly provided in the existing roller skates.
  • the brake member included in the existing roller skate construction is used for braking, this is generally accompanied by the movement of the front wheels out of contact with the ground, which causes the skater to easily lose balance or control.
  • the brake member may be utilized to brake the roller skates while the wheels W_.-W. remain in contact with the ground, thereby better enabling the skater to maintain balance and control during braking.
  • the brake member illustrated in the roller skate of Fig. 10, and therein designated 60 is of generally triangular configuration and is carried by a pair of arms 61, 62 fixed by fasteners (e.g., rivets) 63, 64 to the rear end of the heel plate 14 of base member 6 such that the brake member extends rearwardly of the rear wheel W..
  • Brake member 60 is normally spaced above the ground and therefore ineffective during normal skating.
  • brake member 60 is brought into contact with the ground to produce a braking action. while the wheels W_.-W. remain in contact with the ground to enable the user to maintain stable balance and control during the braking action.
  • roller skate illustrated in Fig. 10 is constructed and operates in the same manner as described above with respect to Figs. 1-7, and therefore the same reference numerals have been used to identify corresponding parts.
  • the pivotal mounting 20 may include a shock absorber, and/or shock absorbers may be provided in the wheel mountings.
  • the above described braking arrangements may also be included in a conventional roller skate. Many other variations, modifications and applications of the invention will be apparent.
