Definitions

  • the present invention relates to a skate.
  • the invention relates more particularly to a skate provided with a runner for transport over ice or provided with a number of wheels (with successively placed wheels in an in-line skate or with wheels placed at offset positions in a roller skate) for land transport.
  • skates with a shoe which can be adjusted such that the shoe size can be modified.
  • an adjustment of the shoe size is important because of the rapid growth of the feet of these children.
  • Skates with an adjustable shoe size can then be used for a longer period of time.
  • Shoe size adjustment of the skate can also be important for adults.
  • Shoe size adjustment of a pair of skates makes it possible for the same pair to be used by different people with differing shoe size. Such people can therefore suffice with the purchase of a single pair of skates. It is also sometimes useful to adjust the shoe size of a skate in changing weather conditions. When the skates are used in cold conditions, the user wears thick socks which in some cases requires a larger shoe size land when the user uses the skate with thin socks, for instance in mild conditions.
  • skates are already known in which the shoe size can be adjusted in more or less successful manner.
  • Known for instance from the international patent application WO 96-40.391 is an in-line skate wherein the heel portion of the shoe is fixed to a frame provided with wheels, while the toe portion of the shoe is fastened to the heel.
  • the toe portion is adjustable in longitudinal direction and thereby provides the option of varying the shoe size of the skate shoe.
  • the adjustment of the shoe size is however rather laborious in the known skate.
  • a bolt must be loosened, the toe portion must be displaced manually and, once the correct shoe size has been set, the bolt must be re-tightened.
  • the American patent US 2003-0,111,808 describes a skate provided with a heel part and a toe part, wherein the toe part can be fixed at a number of positions along the longitudinal axis of the skate so that the shoe size of the skate can be adjusted in a number of fixed steps.
  • fastening of the toe part takes place with a buckle, which does not enhance convenience of use.
  • EP 1,112,698 A2 is an in-line roller skate in which the toe unit of the shoe can be displaced in stepped manner in longitudinal direction after pressing a button.
  • the shoe of the skate In a first position of the shoe the shoe of the skate is locked, while in a second position the shoe can be freely adjusted by the user.
  • the user adjusts the shoe size of the skate by displacing the toe unit of the shoe. Displacing of the toe unit takes place by exerting a manual force on the toe unit.
  • the toe unit is fixed at a desired position by releasing the button.
  • a drawback of the known skate is however that the user must still displace the toe unit of the shoe by hand in order to obtain the desired shoe size.
  • the button must moreover remain pressed-in during this displacement. This limits the convenience of use of the known skate.
  • a skate comprising:
  • the toe part and the heel part are displaced automatically relative to each other, i.e. without intervention by the user, by placing the locking member in the second position. After the locking member has been displaced to the starting position, for instance by releasing thereof, locking of the shoe takes place automatically.
  • An advantage of this skate is that no external, possibly separate assist means such as screwdrivers and the like are required to enable adjustment of the skate.
  • the construction is moreover extremely simple and can be understood by anyone (practically) without instruction.
  • a further advantage is that the skate can be adjusted easily during use. If for instance the feet of the user swell during skating, it can be agreeable to temporarily increase the shoe size of the skate. This increase in the shoe size can be brought about simply by operating the locking member, without the user here having to take off the shoe.
  • the operating component comprises arresting means for arresting the sliding movement of the heel part and/or the toe part after sliding over a set sliding distance.
  • the spring means ensure that the length of the shoe is increased or decreased automatically over the preset distance.
  • the shoe also remains locked in the adjusted position after the locking member has been returned from its second position to its first position. The process of pressing in and releasing the locking member can be repeated, wherein the shoe is displaced a preset distance at a time.
  • the above stated set distance substantially corresponds with a single shoe size unit.
  • shoe size 42 for instance shoe size 42 according to the European system or shoe size 8 according to the British system, can now, simply by operating the operating member a sufficient number of times, set the shoe size to the value suitable for him/her without further operations here being necessary.
  • the spring means are adapted to push the toe part and the heel part away from each other in order to increase the shoe size automatically, i.e. without further intervention by the user.
  • arresting means and the locking member are integrated with each other so that a compact operating unit is obtained.
  • the support element comprises at least two telescopic support element parts.
  • One of the support element parts is herein mounted on the heel part of the shoe, while another support element part is mounted on the toe part of the shoe.
  • a decrease and increase in the shoe size can be realized by respectively sliding the support element parts in and out in longitudinal direction relative to each other.
  • a helical spring which provides the necessary tension between the heel part and the toe part of the shoe.
  • the locking member is provided with spring means for urging the locking member into the first position. This means that, except when it is being operated by the user, the locking member is practically always located in the first position, in which position the shoe is locked. The chance of release during use of the skate is hereby extremely small.
  • the locking member comprises a first stop element which can co-act with protrusions provided on the support element for the purpose of locking the support element when the locking member is located in said first position.
  • the stop element In the first position the stop element remains hooked behind the protrusions so that the support element, and thereby the shoe parts, remain locked relative to each other.
  • the stop element When the locking member is situated in the second position, the stop element is displaced such that it no longer remains enclosed between the protrusions, whereby a displacement of the support element parts, and thereby of the shoe parts, relative to each other becomes possible.
  • the locking member comprises a second stop element which can co-act with one or more teeth provided on the support element for arresting the support element when the locking member is situated in the second position.
  • the second stop element in co-action with said teeth on the support element ensures that the displacement of the support element parts relative to each other can take place through only a limited distance determined mainly by the mutual distance between the teeth. This means that when the locking member is operated the shoe parts are automatically displaced through a predetermined distance relative to each other under the influence of the spring tension.
  • a simple and operationally reliable construction is hereby provided with which the length of the shoe can be adjusted in stepped manner without further intervention by the user.
  • the second stop element is preferably arranged in spring-mounted manner, and said teeth are chamfered in each case on one side while a stop surface is formed on the opposite side.
  • This surface is preferably straight. Owing to this "ratchet" construction the arresting means ensure that, while the support element parts are arrested during displacement in a first direction, the support element parts are not arrested during displacement in another opposite direction.
  • markings representing shoe size are arranged on the one hand on the frame and on the other on the part of the shoe displaceable relative to the frame, for instance in the form of a series of shoe size designations. The user can hereby quickly determine visually the shoe size of the shoe that has been set or is to be set.
  • Figure 1 shows an in-line skate 1 constructed from a plastic frame 2 on which are arranged a number of wheels 4. Wheels 4 are mounted in known manner on frame 2 using wheel axles 3. A different number of wheels can also be applied instead of four.
  • a runner is arranged on frame 2 so that the skate can be used for skating on ice.
  • a braking mechanism 5 is also arranged in known manner on frame 2.
  • Frame 2 comprises a front support leg 13 and a rear support leg 14 on which a plastic shoe sole is arranged in known manner, for instance via pop rivets or a screw connection.
  • Fixed to sole 11 is a shoe 6 which consists of a rear shoe part or heel part 7, which is fixedly attached to sole 11, and a front shoe part or toe part 8 which is displaceable in longitudinal direction of the skate (P 1 ) relative to sole 11.
  • Figure 2 shows a position of the shoe in which the toe of the shoe is displaced forward, and an increased shoe size is therefore realized.
  • An inner shoe 9 is provided which can be arranged in heel part 7 and toe part 8. The shoe can be secured using buckles 10.
  • the front part 8 is slidable relative to the rear part 7 by operating an operating unit 15 shown in more detail in figures 3A and 3B.
  • Figures 3A and 3B show operating mechanism 15 in relation to shoe sole 11 and a displaceable shoe sole part 16 of toe part 8 of the shoe.
  • the slidable shoe part 16 is shown cut-away to some extent so that the operating unit 15 lying thereunder can be seen.
  • the slidable sole part 16 is attached to the support element 17 shown in the figure.
  • Support element 17 can be displaced in an elongate slot 18 provided in sole 11. Displacement of support element 17 in the slot therefore provides for a corresponding displacement of toe part 18 relative to heel part 7 of the shoe.
  • Support element 17 comprises a guide element 19 for guiding the displacement thereof.
  • Guide element 19 is constructed from two telescopic parts and is fixed on one side to support element 17 and on the other side to a support block 21 connected fixedly to sole 11 or formed integrally therewith.
  • a locking mechanism is provided in order to prevent toe part 8 of the shoe always coming to lie in its extreme position with a maximum shoe size as a result of the spring tension of spring 20.
  • the locking mechanism comprises a housing 22 fixed to sole 11.
  • a cylindrical pushbutton 23 is arranged in housing 22.
  • Fixedly connected to this pushbutton 23 is a first stop element 25 which is connected to pushbutton 23 via a connecting piece 26 extending through an opening 27 in support element 17.
  • a displacement of pushbutton 23 therefore also produces a displacement of the first stop element 25.
  • Stop element 25 is held in position by a helical spring 28 provided in housing 22.
  • a second stop element 35 is also provided in spring-mounted manner on pushbutton 23 (using a compression spring 29).
  • Protrusions 30 are provided on support element 17. Protrusions 30 are embodied to accommodate therebetween the protruding part 32 of stop element 25 so that support element 17 can be locked by stop element 25. This situation is shown in figure 4A. Also provided on support element 17 are teeth 36 which can co-act in the manner described below with the second stop element 25.
  • Figure 4B shows the situation in which pushbutton 23 is pressed in by the user (direction P 3 ).
  • pushbutton 23 By pressing in pushbutton 23 counter to the spring action of spring 28 the protruding part 32 of the first stop element 25 moves clear of the protrusions so that support element 17 is no longer arrested by stop element 25.
  • a displacement in longitudinal direction (P 2 ) therefore occurs under the influence of spring 20.
  • An increase in the shoe size of shoe 6 takes place due to the displacement in longitudinal direction of support element 17 and the toe part 8 of the shoe fixed thereto.
  • Figure 4B further shows that as a result of the displacement the outer end of the spring-mounted second stop element 35 has come to lie at the outer end 40 of a tooth 36 and is therefore pressed in counter to the spring pressure of spring 29.
  • the second stop element 35 With further displacement of support element 17 in the direction P 2 the second stop element 35 is pressed against the surface of tooth 36 under the influence of compression spring 29, this such that the chamfered outer end of the second stop element 35 continues to follow the inclining surface 37 of tooth 36.
  • stop surface 43 of the second stop element 35 comes into contact with the straight part 38 of tooth 36, as a result of which support element 17 is arrested by the second stop element 35. It is noted that in this situation the first stop element 25 still does not have a locking function.
  • the toe part 8 of the shoe can be displaced a predetermined distance (a) by pressing in pushbutton 23 and allowing pushbutton 23 to spring back again until the correct length of the shoe is obtained.
  • a predetermined distance a
  • toe part 8 of the shoe has to be pushed in opposite direction, i.e. in the direction of heel part 7.
  • This can be done manually by pushing the front toe part 8 of the shoe counter to the spring pressure of spring 20 in the direction of heel part 7.
  • this pressing-in movement is possible without the stop element 35 blocking support element 17 in any way.
  • the second stop element 35 moreover follows the surface of teeth 36 under the spring tension of spring 29, which results in an up and downward displacement of the second stop element 35.
  • this displacement 35 there occurs a corresponding displacement of the first stop element 25 so that this latter releases locking element 17.
  • FIG. 3A shows that markings are arranged on the outside of the skate with which the user can visually inspect the current shoe size of the skate.
  • Figure 3A for instance shows that a first arrow-shaped marking element 50 is provided on the movable part, i.e. toe part 8 of the shoe, while a number of projections 51 are provided on the stationary part, i.e. on sole 11. Each of the projections corresponds to a specific size of the internal space provided by the shoe. Numerical indications can also be provided instead of or in addition to projections 51 so that the user can determine at a glance the current size of the shoe.
