Description
SKATE BOOT WITH FORWARD FLEXING REGULATOR
FIELD OF INVENTION
This invention relates to in-line roller skates, and in particular, ergonomic in-line roller skates with a forward flexing regulator.
EtACKGROUND OF THE INVENT10N
In traditional skates, foot flexing is limited by the rigidity of the upper cuff which are fior support to the shin. There is a totaity rigid upper cuff and boot and frttle chance for front flexing. Moreover the materials used to make traditional skates an= not such that the skate tends to want to recoil back to its original position.
It is known that experts Pike a lot of flex in the cuff portion of the boot while beginners prefer boots which is more rigid and an upper cuff which is less flexible.
Examples of prior art devices providing ankle flexion are shown in U.S.
patents 5,480,168 and 5,090,138. In U.S. patent 5,480,168, the position of the upper cuff or gaiter relaflve to the lower outer boot is adjustable by means of a fairly complex mechanism involving screws and springs. However, the difficulty of the 2 5 device shown in the 5,480,168 patent is that it dues not permit flexing forward and then backwards but rather maintains the position of the cuff relative to the lower boot in one position.
In U.S. patent 5,090,738, a spring is used, mounted on the side of the boot to 3 0 permit flex in the forward direction and rearward direction with some resistance.
Thus, there appears to be a need to provide a low cost mechanism which wi(I
SUBSTITUTE SHEET (RULE 26) enhance the general flexion properties of the boot, provide better comfort and enhanced performance.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a skate boot permitting forvward flexing to a greater or lesser degree depending on the material used, and yet which will promote recoiling back to the normal position.
1 o It is therefore a further object to the present invention to make front flexing easier, to offier less resistance than with the traditional skate, and to provide a certain amount of nrcoil which tends to move the upper cuff back to its original position.
It is also an object of the present invention to be able to easily replace the flexing mechanism and to be able to change the amount of flexibility in the flexing mechanism to adjust for skaters of d'~fferent levels of competence.
As embodied and broadly described herein, the invention provides a roller skate 2 o boot including a lower outer boot adapted to encompass a fioot of a skater, on upper boot cuff adapted to encompass a lower leg and ankle area of the skater;
said upper boot cuff, in operation, being adapted to pivot forwardly and reannrardly in relation to said lower outer boot, and being pivotally connected thereto; said lower outer boot and said upper boot cuff each including a pair of 2 5 substantially identical asymmetric apertures in the ankle area; said apertures being locat~t on either side of the lower leg; said apertures being aligned between the lower outer boot and the upper boot cuff when the skater's foot and leg are in a normal upright posifbn; said apertures being adapted to matingly engage a flexing regulator of substantially identical asymmetric configuration as 3 0 said apertures; said flexing regulator being constructed of a material which is deformable under a load; wherein, in operation, when a skater flexes a lower leg forwardly, said flexing regulator resists such flexure but permits said upper boot cuff to move forwardly; and when said skater relaxes said lower leg said flexing regulator causes said upper boot cuff to return to its normal upright position.
Advantageously, the skate boot further comprises fastener members adapted to mount said flexing regulators and said upper cuff to said lower boot. The fastener members are preferably co-axial and are adapted to serve as pivot points.
l0 The flexing regulator is advantageously made of an elastomeric material. It is easy to produce, inexpensive and provides good flexion characteristics. It could also be made more or less rigid, depending on the desired amount of flexion.
The forward flexing regulator of the present invention consists of a piece of rubber of flexible material which deforms when one flexes forwardly. When the regulator is worn, the part is interchangeable. To accommodate the flexing regulator, aligned asymmetrical holes or apertures are placed near the ankle area of both the lower boot and the upper cuff. The apertures which are asymmetrical are similar in shape to the flex regulator itself. Thus in the normal 2 o position, the flex regulator offers no resistance. However, when the skater flexes forwardly with the upper cuff there is a load created on the elastomeric flex regulator which tends after the flexing is over to return the upper cuff to the normal position as will be shown in greater detail in the drawings.
2 5 Other objects and features of the invention will become apparent by reference to the following description and the drawings.
