Description
QUARTER FOR SKATE BOOT
Field of the invention The present invention relates to a quarter for a lasted skate boot. It also relates to the skate boot comprising such a quarter.
Background of the invention The prior art quarter were consisting of many separate components. A medial quarter 1 (figure 1 ) and a lateral quarter 2 were manufactured as separate parts. The rear extremities of these parts, corresponding to the heel aid ankle portions of the foot, were then sewn together. A tendon guard 3, also manufactured as a separate part, was finally disposed on the top end of the assembly. With such a realization, the rear part of the skate boot was provided with a sewing line, presenting many disadvantages. For example, the sewing line was difficult to realize when using rigid materials. Moreover, the cambered shape of these elements caused many difficulties to realize the sewing line.
Furthermore, the boot integrity was considerably affected by the presence of a sewing line at the rear part of the boot, this area being subject to very strong constraints. This sewing line was subject to breaking, causing considerable damage to the skate boot. During the assembly process, there was a high probability that the operator set together two similar parts, instead of one medial and one lateral quarters, these parts being very similar. The quality control requirements were very strict, to ensure that the sewing lines were exactly in a straight line. According to prior art realizations, the tendon guard was also placed over the quarters, forming an overlap. This implied additional use of material, additional weight, etc.
Considering the importance of the quarter to produce a high quality skate boot, there is a strong demand for an improved quarter.
Objects and statement of the invention It is thus an object of the invention to provide a quarter for skate boot avoiding the above mentioned drawbacks.
It is another object of the invention to provide an ice skate boot or a roller skate boot provided with such a quarter.
As embodied and broadly described, the invention provides a skate boot comprising a sole, a front portion for enclosing a wearer's toes, a rear portion for enclosing a wearer's heel and ankle, and a medial and lateral portion for enclosing the sides of a wearer's foot. The rear portion and the medial and lateral portions comprise a quarter medial portion and a quarter lateral portion integrally connected together in a one-piece construction and folded at a symmetry line to form a U-shaped skate boot structure. Each quarter portion extends upwardly along the symmetry line defining a heel and ankle portion of the skate boot structure and extends outwardly from the symmetry line in a narrowing profile for defining both sides of the skate boot structure. The skate boot comprises a tendon guard secured to the quarter medial portion and the quarter lateral portion at a junction line in a side-by-side fashion, thereby resulting in the rear portion of said skate boot having an angular profile defined by the tendon guard and the quarter medial and lateral portions at the junction line.
Advantageously, the upper edge of the quarter medial portion defines, with the upper edge of the quarter lateral portion, an angle that is different from an angle defined by a lower edge of the tendon guard such that, when the tendon guard is secured to the quarter medial and lateral portions in a side-by-side fashion, the tendon guard defines an obtuse angle with the quarter medial and lateral portions.
A skate boot provided with such a quarter has a stronger heel portion, without any risk of broken sewing line. It is less expensive to manufacture, with at least
