QUARTER FOR SKATE BOOT

QUARTIER POUR CHAUSSON DE PATIN

English Abstract

A one-piece quarter for a lasted skate boot. It comprises a quarter medial
portion (11), and a quarter lateral portion (13). The quarter medial portion
and lateral portion comprise respectively a foxing medial (12) and lateral
portions (14). The junction line (15) between the lateral and medial portions
defines a symmetry line. A tendon guard (20) is disposed in the upper portion
of the quarter. This tendon guard is preferably sewn to the quarter. The guard
is therefore attached to the quarter, along with the junction line (21).
According to the invention, with a quarter consisting of only one piece, there
is no sewing line along the symmetry line. The skate boot provided with such a
quarter features a stronger heel portion, without any risk of broken sewing
line. It is less expensive to manufacture, with at least one sewing step
eliminated.

French Abstract

L'invention concerne un quartier formé d'une seule pièce pour une chaussure de patin montée. Ce quartier comprend une partie médiane de quartier et une partie latérale de quartier (1). La partie médiane de quartier et la partie latérale (13) comprennent, respectivement, des parties médiane (12) et latérale (14) de bande d'enrobage. La ligne de jonction (15) entre les parties latérale et médiane définit une ligne de symétrie. Un protège-tendon (20) est prévu dans la partie supérieure du quartier. Ce protège-tendon est, de préférence, cousu au quartier. Le protège-tendon est par conséquent fixé au quartier, avec la ligne de jonction (21). Le quartier selon l'invention, composé d'une seule pièce, ne présente plus de ligne de couture le long de la ligne de symétrie. La chaussure de patin pourvue d'un quartier de ce type présente une partie de talon plus résistance, sans risque de rupture de la ligne de couture. Elle est, en outre, moins onéreuse à fabriquer, et il est possible de supprimer au moins une étape de couture.

Description

CA 02302953 2000-03-02 WO 99/12439 PCT/CA98/00845 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. CA 02302953 2001-05-24 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 2 CA 02302953 2001-05-24 one sewing step eliminated. There is no necessity to add additional material to protect the sewing line. A tendon guard is advantageously provided in the upper portion of the quarter. The tendon guard may be partially sewn to the upper portion of the quarter before assembly to the skate boot. The tendon guard and the quarter are connected side by side. As embodied and broadly described, the invention also provides a method of fabricating a skate boot comprising the steps of: A) cutting a one-piece element comprising a quarter medial portion, a quarter lateral portion, a medial foxing portion and a lateral foxing portion, the quarter medial portion and the quarter lateral portion together defining an upper edge of the one-piece element; B) cutting a tendon guard having a lower edge; C) folding the one-piece element at a symmetry line to form a U-shaped structure; D) sewing the lower edge of the tendon guard to the upper edge of the one-piece element end to end to form a butt joint at a junction line, such that the tendon guard defines an obtuse angle with the one-piece element; E) sewing together the medial foxing portion and lateral foxing portion to form a curved heel profile.

According to the invention, the quarter is provided in one piece. It comprises a quarter medial portion 11, and a quarter lateral portion 13. The quarter medial portion 11 and lateral portion 13 comprise respectively a foxing medial and lateral portions 12 and 14. The function line between the lateral and medial portions defines a symmetry line 15. In a variant, a tendon guard 20 is disposed in the upper portion of the quarter. This tendon guard is preferably sewn to the quarter. The guard is therefore attached to the quarter, along with the junction line 21. This junction line is preferably formed by the top bordering of the upwardly extending central section of the quarter. Furthermore, the guard is advantageously disposed side by side with the quarter. This type of joint avoids the formation of any overlapping of the two assembled parts. According to the invention, with a quarter consisting of only one piece, there is no sewing line along the symmetry line 15. The two foxing medial and lateral portions 12 and 14 are advantageously joined together with a sewing line. This assembly line provides an advantageous curved shape for the heel area. For more resistance, the guard and the foxing portions are sewn, in the form of zigzags or saw teeth. '_' S This improved skate boot features a stronger heel portion, without any risk of broken sewing line. It is less expensive to manufacture, with at feast one sewing step eliminated. There is no necessity to add additional material to protect the sewing line.
