- Fig. 1 shows, in side view, a klapskate 1 for athletic sports practice.
- the klapskate 1 is in the normal skating position.
- the skate 1 has a support 3, schematically represented here as footwear enclosing the foot of a user.
- the support 3 is provided with a front sole 5 and a heel section 7.
- a holder 9 connected to the support 3 has an element for contact with the earth's surface, such as a skate blade 11.
- the holder 9 consists of a foremost part 13 and a rearmost part 15 lying in line therewith.
- the foremost part 13 is pivotable about a pivot pin 17 which extends in transverse direction with respect to an imaginary reference plane which extends through the support 3 and the holder 9.
- the foremost part 13 remains substantially in this reference plane.
- the rearmost part 15 is immovably attached to the heel section 7 of the support 3.
- Fig. 2 shows the foremost part 13 with an associated part of the holder 9A and part of the ice blade 11A in a forward pivoted position of the klapskate 1. In this position, the foremost part of the ice blade 11A will remain in contact with the ice surface. In Fig. 2 , the rearmost part 15, which is fixedly attached to the heel section 7, has moved with a rearmost part 11B of the ice blade away from the ice.
- force can still be exerted on the ice with the foremost part 13 of the skate, but the load of the pivot bearing 17 is considerably lower while in this position, also, greater manoeuvrability is obtained.
- a spring may operate for returning the foremost part to the non-pivoted position.
- This spring (not shown but conventional) can return the foremost part 13 to the position of Fig. 1 , after the skate 1 has been lifted in its entirety from the ice from the position in Fig. 2 .
- These springs which are standard in klapskates, are known to the skilled person and can be formed by hairpin springs about the pivot point 17 but also by draw springs which for instance draw a rear end 21 of the foremost part 13 towards the front sole 5.
- Figs. 3 and 4 show a variant wherein the dividing seam 25 runs no longer straight but according to a radius.
- the radius of the dividing seam 25 has the pivot 17 as center point.
- the rear end 21 and the front end 23 of the dividing seam 25 keep running next to each other during pivoting ( Fig. 4 ). This situation can be advantageously used when a suitable dividing seam design of Figs. 5 - 8 is utilized.
- Figs. 5, 6 , 7 and 8 show, schematically and as top plan view, a number of alternative cross sections along the lines D-D in Fig. 1 and Fig. 3 . These cross sections also find application in Figs. 9 and 11 which will be explained in further detail in the following.
- the front end 23 of the rearmost part 15 is guided over at least an important part of the pivoting path with respect to the rear end 21 of the foremost part 13. In this specific combination however, it is of importance that no significant friction can occur between the pivoting foremost part and the fixed rearmost part. It may also be necessary with the design according to Figs. 3 and 4 to dimension the dividing seam to be somewhat wide, so that there is no risk of ice, snow or dirt hindering the pivotability.
- Fig. 6 shows a so-called tongue and groove variant wherein a tongue 27 engages a groove 29.
- An undesired lateral movement can thus be completely precluded and the forces on the pivot 17 can also be restrained.
- a similar effect can be achieved with the pointed variant according to Fig. 7 or the round variant according to Fig. 8 .
- This design can find application in the embodiment according to Fig. 1 and 2 too, but in that case has effect only in the non-pivoted position (according to Fig. 1 ). It goes without saying that in the skating position, it is of the utmost importance that the alignment of the skate blades be good and immovable for achieving peak performances.
- a further alternative variant of the klapskate according to the invention is shown, wherein the dividing seam 25 is designed diagonally in vertical direction, in a manner such that this dividing seam is positioned further forward at the side than at the bottom.
- a stop becomes superfluous because the closing position is defined by the dividing seam itself.
- Figs. 11 and 12 show yet another variant with a diagonal dividing seam 25.

- the cross section D-D can use one of the designs from Figs. 5 - 8 .
- the pivot connection between the foremost part 13 and the front sole 5 is represented as a pivot connection with a pivot pin 17 as transverse pivot axis. It will be clear to the skilled person that to this end, also, a pivot connection from flexible, optionally resilient material can be used. It is also possible to use more than one pivot axis. For a more detailed description of such multi-axial systems, reference is made to the descriptions in NL1003205 , NL 1008647 , US 6,082,744 and/or NL 1011985 .
- a set up directed at an inclination can be chosen which takes the angle at which the human leg moves during skating into account.
- NL1014462 and/or NL1014318 can be found in, inter alia, NL1014462 and/or NL1014318 .
- a simple manually-operable locking means can be provided which is designed as a sliding part that can simultaneously comprise adjacent parts of the foremost and rearmost part. More complex systems too can be eligible as locking, and examples thereof are described in NL 8500483 , NL1001618 , NL1007725 , NL 1008109 and/or NL1008898 .
- Figs. 13 and 14 are schematic side views of an inline roller skate which is not part of the invention, wherein the earth surface contact element is formed by a wheel system. Instead of a skate blade, here, on the foremost and rearmost part 13, 15 of the support, a system of wheels 30A, 30B, 30C and 30D is provided.

Description
- The invention relates to an aid to be temporarily fastened to a human leg for practicing athletic sports, such as notably an ice skating. More particularly, the invention relates to an improved klapskate, this being understood to include both ice skates and inline roller skates.
- The principle of the known klapskate has its origin in a German patent publication
DE78733 from 1894, while after this, similar skates have been suggested too, as inUS 1,789,182 . This type of skate, however, has become widely known only after its development from kinesiology for competitive long distance skating. Instead of the blade of a skate being fixedly connected, in a customary manner, at the front and the rear to a shoe, with the klapskate, the skate blade is pivotably attached to the front of the shoe. With the aid of a spring mechanism, the skate blade is held against a point of support at the rear of the shoe. With this, during skating, a better rolling of the foot is obtained, so that the push-off leg of the skater too can be stretched completely before it is lifted from the ice. With this type of skate, indeed; better results have been achieved in the international skating sports. Sometimes mentioned as a drawback of the klapskate is the loss of the possibility of making a "point start", whereby grip is obtained on the ice with the tip of the skate blade. While it may be true that solutions to this drawback have been suggested which temporarily fix the skate blade of the klapskate, these solutions are in part unpractical, or even in violation of the regulations for international skating laid down by the ISU, so that they cannot be used in competitive sports. With klapskates of the customary model, the pivotable attachment is located at the front at approximately one third or less of the length of the blade from the tip of the blade. When, with the foot part pivoted up, the point of support at the heel side is inoperative, over two-thirds of the length of the skate blade is to be kept under control by the pivot attachment at the front. This not only sets high standards to the design of the pivot connection, but renders the use of the skate susceptible to wear too. Especially upon push-off, but also in bends, optimum transmission of the force from the skater's heel is very important. To this end, especially a fixed and stable connection to the skate blade is required. The known klapskate cannot always meet these requirements due to, inter alia, wear to the pivot connection or to the heel support. Nonetheless, for optimal use of the force exerted during the skate stroke, the possibility of rolling the foot remains very important. When using racing skates of the Norwegian type, in addition to the need for a better rolling of the foot, the manoeuvrability of these skates designed for speed leaves to be desired. Skates especially designed for manoeuvrability, such as hockey skates or figure skating skates, have considerable shorter blades. - In this regard, it is noted that document
DE 297 04 662 discloses an inline roller skate that is provided with a support equipped with a front sole and a heel section for supporting a human foot, and a holder connected to the support. In this roller skate, which is only concerned with the conditions of a relatively high friction road surface, the holder is provided with a foremost part in direction of movement, having a front set of rollers, and a rearmost part, having a rear set of rollers. In the proximity of the front sole, the foremost part of this known roller skate is pivotably connected to the support to be swivable about at least one transverse pivot axis extending in-between the rollers of its front set of rollers. The rearmost part of this known roller skate is immovably attached to the support in the proximity of the heel section and is not met by the foremost part when this is in a non-swivelled position. - Accordingly, it is at least an object of the present invention to eliminate or meet at least one of the drawbacks of the state of the art. More particularly, it is an object of the invention to provide the long distance skates now in use with new properties. In this type of skate, in particular properties in the field of freedom of movement of joints, manoeuvrability and stability were supposedly impossible to combine. It is also an object of the present invention to provide alternative constructions which are easier in manufacture and use and which can furthermore be made relatively advantageously. Alternatively, it is an object of the invention to provide the public with an at least useful choice.
- To that end, the invention provides an ice skate, provided with a support equipped with a front sole and a heel section for supporting a human foot, and a holder connected to the support, having a skate blade, wherein the holder is provided with a part foremost in direction of movement and a rearmost part provided in line with the foremost part, wherein, in the proximity of the front sole, the foremost part is connected to the support so as to be pivotable about at least one transverse pivot axis, for a pivotal movement in a reference plane extending both through the support and the holder, and wherein the rearmost part is immovably attached to the support in the proximity of the heel section, wherein the foremost part in non-pivoted position links up by a rear end with a front end of the rearmost part along a dividing seam in the holder.
- With such an ice skate or klapskate, it can be advantageous that the pivotal movement of the foremost part takes place between a non-pivoted position and a completely pivoted position so that thus, a sufficient degree of rolling of the foot of a user of the ice skate can be guaranteed. Then, also, a spring can be utilized, operating between the support and the holder, which can move the foremost part back to the non-pivoted position.
- It is also advantageous when the dividing seam is of diagonal design. The dividing seam can further be provided with mutually cooperating tongue and groove sections. More particularly, it can be provided that in the non-pivoted position, in all directions of a normal load, the foremost part, with a rear end engaging a front end of the rearmost part, is immovably connected thereto. Also, guide means can be provided with which the rear end of the foremost part, upon pivoting, is guided with respect to the front end of the rearmost end.
- The pivotability about the transverse pivot axis can be effected at will by a pivot point provided with a pivot pin, or by a flexible, optionally resilient, connection. Also, for the pivotability of the foremost part, a second transverse pivot axis can be utilized which can be placed in the direction of movement in front of the first transverse pivot axis. Then, if desired, the second transverse pivot axis can be activated later in the pivotal movement effected by rolling of the foot than the first pivot. Also, if required, at least one of the first and second transverse pivot axes can be directed so as to be at an inclination with respect to the reference plane.
- In general, it may be useful to have the position of the foremost part in the non-pivoted position be determined more precisely by a stop means. Here, the stop means too can be designed to be at least partly resilient and elastic. Also, a locking means can be provided, with which the pivotal movement of the foremost part in the non-pivoted position can be blocked, at least temporarily. The locking means can then be designed as a sliding part, which can simultaneously enclose the foremost and rearmost part of the holder. If desired, the locking means may be unlocked electromagnetically. Also, with the aid of magnetic attraction, the position of the foremost part, in the non-pivoted position of this foremost part, can be defined more precisely. Alternatively, it is also possible to even exert a slight take off pressure when rolling the foot, by means of two repelling magnet poles. With this, also, the effect of friction can be reduced.
- It is customary with this sort of ice skate to have the front sole and the heel section form part of footwear enclosing the foot of a user.
- The skate blade can be manufactured from steel, provided or not provided with a coating, from sintered metal or even from ceramic material.
- The invention further relates to a combination designed as a pair of skates having, in each case, an ice skate of the type described hereinabove designed as left and right skate, wherein details relevant thereto in the right and the left skate are designed to be mirror symmetrical.
- Presently, the invention will be described in further detail on the basis of the appended
drawings 1 to 12. In the drawings: -
Figs. 1 and 2 are side views of a klapskate according to the invention in the skating position and the forward pivoted position, respectively; -
Figs. 3 and 4 are side views of an alternative embodiment for a klapskate according to the invention in the same positions as inFigs. 1 and 2 ; -
Figs. 5, 6 ,7 and 8 are alternative designs of the dividing seam, according to the cross sections D-D in, inter alia,Figs. 1 and3 ; -
Figs. 9 and 10 are side views of another alternative embodiment of a klapskate according to the invention in the same positions as inFigs. 1 and 2 ; -
Figs. 11 and 12 are side views of another alternative embodiment of a klapskate according to the invention in the positions ofFigs. 1 and 2 ; and -
Figs. 13 and 14 are side views of an inline roller skate, which is no part of the invention, to which also a magnetically supported closing movement variant is added. -
Fig. 1 shows, in side view, aklapskate 1 for athletic sports practice. InFig. 1 , theklapskate 1 is in the normal skating position. Theskate 1 has asupport 3, schematically represented here as footwear enclosing the foot of a user. Thesupport 3 is provided with a front sole 5 and aheel section 7. Aholder 9 connected to thesupport 3 has an element for contact with the earth's surface, such as askate blade 11. Theholder 9 consists of aforemost part 13 and arearmost part 15 lying in line therewith. Theforemost part 13 is pivotable about apivot pin 17 which extends in transverse direction with respect to an imaginary reference plane which extends through thesupport 3 and theholder 9. Upon pivoting, as shown inFig. 2 , theforemost part 13 remains substantially in this reference plane. Therearmost part 15 is immovably attached to theheel section 7 of thesupport 3. -
Fig. 2 shows theforemost part 13 with an associated part of theholder 9A and part of theice blade 11A in a forward pivoted position of theklapskate 1. In this position, the foremost part of theice blade 11A will remain in contact with the ice surface. InFig. 2 , therearmost part 15, which is fixedly attached to theheel section 7, has moved with arearmost part 11B of the ice blade away from the ice. Thus, it is achieved, inter alia, that during rolling of the foot of the skater, force can still be exerted on the ice with theforemost part 13 of the skate, but the load of the pivot bearing 17 is considerably lower while in this position, also, greater manoeuvrability is obtained. For a good alignment of the foremost andrearmost ice blades stop 19. Further, between thesupport 3 or the front sole 5 and theforemost part 13 of theholder 9, a spring may operate for returning the foremost part to the non-pivoted position. This spring (not shown but conventional) can return theforemost part 13 to the position ofFig. 1 , after theskate 1 has been lifted in its entirety from the ice from the position inFig. 2 . These springs, which are standard in klapskates, are known to the skilled person and can be formed by hairpin springs about thepivot point 17 but also by draw springs which for instance draw arear end 21 of theforemost part 13 towards the front sole 5. Often, such draw springs can be hooked in at will at a number of places so that an adjustable spring tension is obtained. In closed position (Fig. 1 ) therear end 21 of theforemost part 13 links up with afront end 23 of therearmost part 15 and then forms adividing seam 25 in theholder 9. - The
Figs. 3 and 4 , in which for a better understanding, as much as possible, the same reference numerals will be used, show a variant wherein thedividing seam 25 runs no longer straight but according to a radius. The radius of thedividing seam 25 has thepivot 17 as center point. As a result, therear end 21 and thefront end 23 of thedividing seam 25 keep running next to each other during pivoting (Fig. 4 ). This situation can be advantageously used when a suitable dividing seam design ofFigs. 5 - 8 is utilized. -
Figs. 5, 6 ,7 and 8 show, schematically and as top plan view, a number of alternative cross sections along the lines D-D inFig. 1 andFig. 3 . These cross sections also find application inFigs. 9 and11 which will be explained in further detail in the following. When, with the embodiment ofFig. 3 and 4 , instead of the straight design according toFig. 5 , one of the contours according toFigs. 6 ,7 or 8 is used, then, thefront end 23 of therearmost part 15 is guided over at least an important part of the pivoting path with respect to therear end 21 of theforemost part 13. In this specific combination however, it is of importance that no significant friction can occur between the pivoting foremost part and the fixed rearmost part. It may also be necessary with the design according toFigs. 3 and 4 to dimension the dividing seam to be somewhat wide, so that there is no risk of ice, snow or dirt hindering the pivotability. -
Fig. 6 shows a so-called tongue and groove variant wherein atongue 27 engages agroove 29. An undesired lateral movement can thus be completely precluded and the forces on thepivot 17 can also be restrained. A similar effect can be achieved with the pointed variant according toFig. 7 or the round variant according toFig. 8 . This design can find application in the embodiment according toFig. 1 and 2 too, but in that case has effect only in the non-pivoted position (according toFig. 1 ). It goes without saying that in the skating position, it is of the utmost importance that the alignment of the skate blades be good and immovable for achieving peak performances. - In
Figs. 9 and 10 , a further alternative variant of the klapskate according to the invention is shown, wherein thedividing seam 25 is designed diagonally in vertical direction, in a manner such that this dividing seam is positioned further forward at the side than at the bottom. With such a diagonal design of the dividing seam, a stop becomes superfluous because the closing position is defined by the dividing seam itself. For the design of the front andrear surfaces Figs. 5, 6 ,7, or 8 respectively can be utilized. -
Figs. 11 and 12 show yet another variant with adiagonal dividing seam 25. Here, the dividing seam has a stepped shape. This is a suitable embodiment when thesupport 3 is to be kept free from reactive forces such as they could be formed in a diagonal dividing seam according toFigs. 9 and 10 . Here too, the cross section D-D can use one of the designs fromFigs. 5 - 8 . - In the described embodiments, the pivot connection between the
foremost part 13 and the front sole 5 is represented as a pivot connection with apivot pin 17 as transverse pivot axis. It will be clear to the skilled person that to this end, also, a pivot connection from flexible, optionally resilient material can be used. It is also possible to use more than one pivot axis. For a more detailed description of such multi-axial systems, reference is made to the descriptions inNL1003205 NL 1008647 US 6,082,744 and/orNL 1011985 - For the angle the transverse pivot axis makes with the reference plane through the
support 3 and theholder 9, also, a set up directed at an inclination can be chosen which takes the angle at which the human leg moves during skating into account. A more detailed description of this can be found in, inter alia,NL1014462 NL1014318 - When starting the skating movement, it can sometimes be desired to lock the
foremost part 13 with respect to therearmost part 15 in the non-pivoted position. Thereto, a simple manually-operable locking means can be provided which is designed as a sliding part that can simultaneously comprise adjacent parts of the foremost and rearmost part. More complex systems too can be eligible as locking, and examples thereof are described inNL 8500483 NL1001618 NL1007725 NL 1008109 NL1008898 Figs. 13 and 14 are schematic side views of an inline roller skate which is not part of the invention, wherein the earth surface contact element is formed by a wheel system. Instead of a skate blade, here, on the foremost andrearmost part wheels - Also, a magnetically-supported closing movement variant is added. Instead of springs, such as a hairpin spring or a draw spring, for returning the
foremost part 13 to the non-pivoted position, also, magnetic fields can be used for moving the foremost skate part back to its initial position. With the improved klapskate according to the invention, the pivotableforemost part 13 is virtually in balance. This means that thepivot axis 17 is in the proximity of the center of gravity of theforemost part 13. As a result, under the influence of gravity, the pivoted position thereof will position itself substantially parallel to the earth's surface. It is therefore not required that over the entire path of the pivotal movement a force is exerted for returning theforemost part 13 to its non-pivoted position. On the front sole part of thesupport 3, afirst magnet 31 is provided and on a part of theforemost part 13 lying in front of thepivot 17, asecond magnet 33 is provided. The poles of the first andsecond magnet foremost part 13, a decreasing returning force is exerted. Alternatively, or in combination with the first andsecond magnets third magnet 35 can be provided in line with the rearmostdividing seam surface 23 of therearmost part 15. Afourth magnet 37 is then provided on a part of theforemost part 13 lying behind thepivot axis 17.
