This application claims priority to European patent application EP 23 186 028.9, filed Jul. 18, 2023, the entire content of which is incorporated herein by reference.
The present disclosure relates to a sports shoe and an adjustment device for a sports shoe.
Today's sports shoes for inline skates comprise a foot shell for a foot portion and a cuff for a calf area. However, there are different cuffs and cuff types for these sports shoes, which also have differently arranged attachment openings and therefore do not always fit the respective foot shell.
It is therefore an object of the disclosure to increase the compatibility of a sports shoe.
This object is achieved by a sports shoe and an adjustment device for adjusting an attachment position of a cuff to a foot shell of a sports shoe, as described herein.
According to a first aspect, the object is achieved by a sports shoe comprising a foot shell for a foot portion. The sports shoe can comprise the cuff. The adjustment device allows the attachment position of the cuff to the foot shell to be changed horizontally and/or vertically. The adjustment device achieves the technical advantage that different cuffs can be used at different attachment positions in connection with the foot shell. In addition, the attachment position of the cuff can be adjusted to the needs of a user.
In a technically advantageous embodiment of the sports shoe, the adjustment device is arranged in the ankle joint area of the foot shell. This achieves the technical advantage, for example, that the adjustment device is provided at a particularly suitable position of the sports shoe.
In a further technically advantageous embodiment of the sports shoe, the adjustment device is arranged on an outer side of the foot shell. This achieves the technical advantage, for example, that the adjustment device is easily accessible.
In a further technically advantageous embodiment of the sports shoe, the adjustment device comprises a foot shell part and a cuff attachment part which is lockable at several positions of the foot shell part. The foot shell part and the cuff attachment part interact to spatially change the attachment position of the cuff. For example, the cuff attachment part is fixable vertically, horizontally and diagonally at different positions on the foot shell part. This achieves the technical advantage, for example, that the attachment position of the cuff can be flexibly adjusted.
In a further technically advantageous embodiment of the sports shoe, the foot shell part is formed by a circular disk. This achieves the technical advantage, for example, that the foot shell part can be easily integrated into the foot shell.
In a further technically advantageous embodiment of the sports shoe, the foot shell part comprises a recess for inserting the cuff attachment part. This achieves the technical advantage, for example, that the cuff attachment part can be reliably attached.
In a further technically advantageous embodiment of the sports shoe, the circumference of the recess is composed of several circular arcs. This achieves the technical advantage, for example, that the cuff attachment part can be fixed in each of the circular arcs and any forces that occur are transmitted well.
In a further technically advantageous embodiment of the sports shoe, the cuff attachment part comprises a projection for positive engagement in the recess of the foot shell part. The projection has a shape that corresponds to the recess in the foot shell part. This also achieves the technical advantage, for example, that the cuff attachment part can be fixed in each of the circular arcs.
In a further technically advantageous embodiment of the sports shoe, the projection comprises a protruding cylinder portion for attaching the cuff. This achieves the technical advantage, for example, that the position of the cylinder portion can be changed.
In a further technically advantageous embodiment of the sports shoe, the protruding cylinder portion comprises a thread for screwing in a fastening screw. This also achieves the technical advantage, for example, that the cuff can be reliably attached to the cylinder portion.
In a further technically advantageous embodiment of the sports shoe, the cuff attachment part is rotatable relative to the foot shell part. This also achieves the technical advantage, for example, that the position of the cuff attachment part can be easily adjusted.
In a further technically advantageous embodiment of the sports shoe, the cuff attachment part comprises a central recess for inserting a rotating tool. This achieves the technical advantage, for example, of making it easier to rotate the cuff attachment part.
According to a second aspect, the technical task is solved by an adjustment device for adjusting an attachment position of a cuff to a foot shell of a sports shoe, comprising a foot shell part which is connectable to a foot shell or is integrated in the foot shell; and a cuff attachment part which is lockable at several positions with the foot shell part and to which the cuff can be attached. The adjustment device achieves the same technical advantages as the sports shoe according to the first aspect.
In a technically advantageous embodiment of the adjustment device, the foot shell part comprises a recess for inserting the cuff attachment part, the circumference of which is composed of several circular arcs. This achieves the technical advantage, for example, that the cuff attachment part can be fixed in each of the circular arcs.
In a further technically advantageous embodiment of the adjustment device, the cuff attachment part is rotatable relative to the foot shell part. This achieves the technical advantage, for example, that the position of the cuff attachment part can be easily changed in relation to the foot shell part.
The disclosure will now be described with reference to the drawings wherein:
With a soft shell, a shell skeleton made of plastic is used. The upper material of the shoe can then be made of nylon, polyester, synthetic leather or leather. In addition, the sports shoe 100 comprises a cuff 105. The cuff 105 is a component of the sports shoe 100. The cuff 105 protects and supports the foot shell 103.
The sports shoe 100 comprises a rivet-free rotatable adjustment device 107 (Revolve Anti Rivet Cuff System) for variably attaching the cuff 105 to different attachment positions of the foot shell 103. The adjustment device 107 is arranged in the ankle joint area and on an outer side of the sports shoe 100. The adjustment device 107 comprises a foot shell part and a cuff attachment part, which is lockable at several positions of the foot shell part. The cuff 105 is in turn attached to the cuff attachment part.
The cuff 105 is attached in the foot shell part in a first position 1, which is above the axis of rotation of the adjustment device 107. Vertically below position 1 is position 4, at which the cuff 105 lies below the axis of rotation of the adjustment device 107. In position 4, the cuff 105 is therefore attached below position 1. Positions 1 and 4 allow a first type of cuff to be attached, for example.
By turning the adjustment device 107 clockwise or counterclockwise, the cuff 105 can be shifted upwards, downwards, forwards or backwards. This makes it possible to use different cuffs 105 for the sports shoe 100 in combination with the foot shell 103, such as cuffs from different manufacturers. The adjustment device 107 allows the sports shoe 100 to be adjusted to differently designed cuffs 105.
The ring-shaped foot shell part of the adjustment device 107 can be integrated into a hard shell of the sports shoe 100 as a foot shell portion. In this case, the foot shell part is formed by the foot shell 103 itself. The ring-shaped foot shell part may also have been overmolded in the foot shell in an injection molding process. In this case, the foot shell part is arranged within the foot shell 103.
The ring-shaped foot shell part can also be realized by a separate foot shell part made of plastic, such as an adapter (plastic patch adapter), and attached to a soft shell of the sports shoe 100, for example by sewing the foot shell part to the soft shell. In this case, the adjustment device 107 comprises two individual interacting parts.
In position 3, the adjustment device 107 is rotated another 60° clockwise relative to position 2. This results in two further attachment positions for the cuff 105, which are shifted forwards. Positions 2 and 3 allow a second type of cuff to be attached, for example.
In position 5, the adjustment device 107 is rotated counterclockwise by another 60° relative to position 6. This results in two further attachment positions for the cuff 105, which are shifted backwards and downwards. Positions 5 and 6 allow a third type of cuff to be attached, for example. In total, the adjustment device results in six adjustable positions for attaching the cuff 105 to the foot shell 103.
The cuff attachment part 109 comprises a projection 115 for positive engagement with a corresponding recess in the foot shell part. The projection 115 is formed on a disk-shaped base 129. The projection 115 protrudes from the circular base 129 of the cuff attachment part 109.
The projection 115 has a triaxial symmetry, from which the six attachment options of the adjustment device 107 result. The circumference of the projection 115 is composed of several circular arcs. In each of the six circular arcs there is an opening 131. Between each of the circular arcs of the projection 115, the base 129 comprises notch-shaped recesses 127 which are distributed around the circumference of the base 129. The notch-shaped recesses 127 positively engage corresponding portions of the foot shell part and additionally prevent unintentional rotation of the cuff attachment part 109. In addition, the notch-shaped recesses 127 support the cuff attachment part 109. In general, the projection 115 or the cuff attachment part 109 can also have a different shape.
In addition, the projection 115 comprises a cylinder portion 123, which protrudes again and has an internal thread 119. The overhang of the cylinder portion 123 relative to the projection 115 is, for example, 4 mm. The cuff 105 is attached to this cylinder portion 123 by means of a fastening screw, such as an M6 screw.
A central, hexagonal recess 125 for inserting a rotating tool is located in the center of the cuff attachment part 109. The recess 125 can also be formed in a star shape so that a Torx screwdriver can be used. By means of the rotating tool, the cuff attachment part 109 can be brought into the correct position. As a result, the cylinder portion 123 can be brought into one of the positions 1 to 6, depending on the type of cuff to be attached, and fixed there.
There is a further recess 135 on the rear of the foot shell part 111, the shape of which corresponds to the base 129 with the notch-shaped recesses 127. This achieves a further form fit.
The cuff 105 is attached to the cylinder portion 123, the position of which can be changed depending on the insertion position of the cuff attachment part 109. Due to the rotating construction of the adjustment device 107, it is possible to attach different cuffs from different manufacturers to the foot shell 103.
The cuff attachment part 109 can be brought into different positions from outside the foot shell using the rotating tool 121. By turning the adjustment device 107, the attachment position for the cuff 105 can be spatially changed vertically and horizontally.
All the features explained and shown in connection with individual embodiments of the disclosure can be provided in different combinations in the subject matter according to the disclosure in order to realize their advantageous effects at the same time.
The scope of protection of the present disclosure is given by the claims and is not limited by the features explained in the description or shown in the figures.
