Definitions

  • the invention generally pertains to poles for skiing or walking, and more particularly to a holder, a hand support, a ski pole assembly and a ski pole.
  • Hand held poles are commonly used for maintaining balance and increasing speed when skiing or walking. Examples of such poles are cross-country ski poles, alpine ski poles, nordic poles and walking poles.
  • the poles traditionally have a handle at the top for the hand of a user to grip comfortably around and a strap to be put around the user's wrist.
  • the skiers wrist pivots such that the top of the pole is pushed away and the length of the pole-push is increased.
  • the skiers hand is in other words used as a lever to push the pole further backwards. This increases the speed of skiing.
  • the user may loosen their grip around the handle at the end of pole-pushing, in order to increase the reach.
  • the strap prevents dropping the pole.
  • EP2135646A2 discloses a ski pole with a hand grip arranged at the upper end of a shaft and with a holding means through which the hand of a user is substantially fastened to the upper end portion of the shaft, while allowing a pivoting movement of the hand with respect to the upper end portion.
  • the holding means comprises a support member for supporting the palm of the hand and the pivoting axis is above the hand.
  • EP3632514A1 discloses a similar setup with a hand grip and holding means for pivotal connection of the hand to the top of a pole.
  • an element projects forward from the top of the ski pole, onto which a support member of the holding means is pivotally connected. Thereby, the pivoting axis is displaced from the top of the pole and the lever of the skiers hand is increased.
  • the object of the present invention is to provide a ski pole assembly for a ski pole being improved in at least one aspect with regard to ski poles in the prior art. More specifically, an object is to provide a ski pole assembly that is improved in at least one of increased lever possibility of the users hand (and thereby pole-pushing length), product durability, stability, weight and versatility, while preferably being cheap and easy to manufacture.
  • the present invention specifically relates to a holder, a hand support, a ski pole assembly comprising these and a ski pole comprising such a ski pole assembly. While the invention is particularly directed to cross-country ski poles, the same principle can be applied to other ski poles or walking poles. References to ski poles and skiing made herein are used for explanatory reasons and is not to be interpreted as limiting the application of the invention thereto.
  • a holder for a ski pole assembly comprising a stick connecting portion for rigid connection to a stick, which has a lower end configured to be attached to an upper end of a stick and an opposite upper end.
  • the holder also comprises a bracket portion extending from the stick connecting portion.
  • the holder further comprises a hand support connecting part located on the bracket portion. It is suitable for pivotal connection to a hand support, such that a connected hand support is pivotable around a pivot axis of the hand support connecting part, between a closed position and an open position, when connected.
  • the holder further comprises a support surface, positioned to receive an axial force exerted from such a connected hand support in the closed position, when the hand support is pushed downwards in a direction aligned with the central axis of the intended placement of a stick. Substantially no axial force is thereby be transferred to the hand support connecting part from the hand support when the hand support is in the closed position and being pushed downwards.
  • the holder is configured to function as a means for connecting a hand support to a stick part of a pole, such as for example a ski pole or a walking pole.
  • the stick part is an elongated shaft.
  • the stick connecting portion is configured to be rigidly connected to the upper end of a stick.
  • Rigidly means that is fastened such that it does not wiggle or loosen during use. It could be removable or it could be permanently fastened to the top of a stick.
  • the lower end of the stick connecting portion is a side which is in contact with the upper end of the stick when connected. It is designed to facilitate the fastening of the holder to a stick.
  • the bracket portion extends from the stick connecting portion in order to enable the hand support connecting part, which is located on it, to be placed a distance from the stick connecting portion and thereby from the top of the stick.
  • the hand support connecting part is configured to be able to be connected to a hand support in a way that allows a pivotal movement of the hand support in relation to the holder.
  • the pivotal movement has a pivot axis, which is based on the location and shape of the hand support connecting part.
  • the shape of the bracket portion should be designed to enable a desired location of this pivot axis in relation to the stick at the same time as it should be sturdy but not unnecessarily large.
  • a connected hand support is in contact with the holder at least by the hand support connecting part. Apart from this, it may also be, at least in the closed position, in contact with a support surface on the holder. In the closed position, when a user pushes the pole down, a force is applied from a connected hand support onto somewhere on the holder, in a direction downwards. Downwards in this context denotes the direction along where the central axis of a connected stick would be located, towards the bottom end of the stick.
  • the support surface of the holder is configured to function as a receiver of this force. This way, the full force is not applied onto the hand support connecting part or a corresponding holder connecting part on a hand support. These parts may be vulnerable and prone to breaking or wearing.
  • substantially no pulling force is applied on the hand support connecting part due to the support surface hindering the hand support from being pushed further down. This increases the durability of the holder and also of a connected hand support, as a connecting part such as a joint being pulled at every pole-push is a likely break down point.
  • connection between the holder and a hand support is pivotal, meaning that the hand support can swing away from the holder and thereby from a connected stick. It may also be fully disconnectable without breaking any parts, preferably easily and quickly, such that a holder can be used with several different hand supports. This makes it possible to permanently connect a holder to a stick, while being able to switch between different hand supports. It is also possible to use one hand support for several different holders rigidly attached to different sticks. If the hand is fastened to the hand support such that it is complicated or time consuming to take off, the whole hand support can be conveniently loosened from the pole, while the holder stays on the pole.
  • the support surface may be substantially orthogonal to the axial force. This means that it is also substantially orthogonal to the central axis of a connected stick. A flat such surface distributes the force over a larger area, which decreases vulnerability compared to if it would be a pointy region.
  • the support surface may be located on the stick connecting portion. This is the most sturdy option, especially in cases where the bracket portion extends forwardly from the stick connecting part.
  • the support surface is preferably mainly located above the stick, as placing it on parts extending horizontally from the stick would render those prone to breaking.
  • the bracket portion may comprise two side portions divided by a recess.
  • the recess may reach into a part of the bracket portion or all the way through the bracket portion such that is reaches the stick connecting portion.
  • the bracket portion is then mostly or entirely divided into two portions.
  • At least a part of the support surface may be positioned in between the side portions.
  • the recess thereby increases the available area of a support surface. It may also increase stability, as a part of a hand support enters the recess when going into the closed position and is then hindered from wiggling sideways by the two side portions. It may guide the hand support towards a correct closed position during closing and stabilize the hand support during the push towards the holder.
  • the pivot axis of the hand support connecting part may be located at a first forward distance being up to 6 cm in a forward direction from the central axis of the intended placement of a stick.
  • Forward is a direction perpendicular in relation to the central axis of an imaginary connected stick, i.e. it is in the horizontal plane, directed away from a closed connected hand support and the hand of a user. In other words, forwardly from the shaft in the traveling direction of a user when the stick is extending vertically from the ground.
  • This perpendicular distance representing the relative location of the pivot axis, affects the lever of the hand.
  • This lever will be substantially increased at the beginning of the pivoting of the hand support with respect to the stick by displacing said pivot axis forwardly with respect to the stick. The greater this lever is the more speed may be accomplished.
  • the forward displacement may also facilitate the incorporation of other features on the holder, such as a support surface.
  • the pivot axis of the hand support connecting part may be located at a first upward distance being up to 6 cm in an upward direction from the stick connecting portion.
  • Upward is the direction aligned with the central axis of an imaginary connected stick, in the direction from the lower end of the stick (the end which is generally nearer to the ground in use) and through the upper end of the stick, where a holder may be connected.
  • This upward displacement results in an increased vertical distance between the pivot axis and the hand wrist of a user, which improves the efficiency of the pole-pushing especially in the middle and end phase of a pivot movement of the hand support.
  • the hand support connecting part may be located such that the nearest point on the pivot axis of the hand support connecting part is located at an angle being from 10 to 70 ° in relation to an imagined prolongation of a central axis of the intended placement of a stick.
  • the nearest point on the pivot axis is the point on the pivot axis (which axis runs through the hand support connecting part and is the centre of the swinging motion of a connected hand support) which is closest to where the central axis of a connected stick would be. In other words, it is located straight in the forward direction from a point on an imagined prolongation of such a central axis, which prolongation is directed upwards from the stick.
  • the angle is measured in relation to this imagined prolongation at a point vertically located at the upper end of the stick connecting part, where the bracket portion extends from.
  • a greater angle ⁇ (i.e. a more forwardly inclined angle) gives a more efficient start of the pivot movement of the hand support and a longer lever. But a greater angle at a fixed length of the pivot axis from the upper end of the stick lowers the efficiency of the pole pushing at the end of the pivot movement in comparison to a smaller such angle. Larger angles will in other words increase the lever for pushing the skier forwardly in the beginning of a stroke.
  • a suitable angle should be chosen depending on the desired pushing effect.
  • the bracket portion may have a back surface and a front surface, each extending from the stick connecting portion towards a distal end of the bracket portion where the hand support connecting part is located, wherein the back surface and the front surface are substantially straight.
  • the bracket portion could have a variety of shapes, like being curved or comprising several bends or being directed first upwards and then forward or vice versa, a preferred embodiment is where it extends from the stick connecting part with substantially straight side surfaces. If the pivot axis is located both upward and forward from the stick connecting part, the bracket portion extends as a substantially straight part leaning forwards. This decreases risk of cracking under pressure and minimizes material usage.
  • the hand support connecting part may be a joint or a receiving element configured to engage with a joint.
  • a receiving element may be a recess into the bracket portion into which a joint fits and can be pivotally connected.
  • the holder may comprise a spacing projection extending from the holder towards the intended placement of a hand support. This is at least in part in a backwards direction, in relation to the before mentioned forward direction of the holder. It may thereby maintain a distance between the stick and hand support when abutting the hand support in a closed position and/or stabilize the placement of a hand support in a closed or near closed position by hindering it from moving sideways. It may act as a guiding element, which enters a recess in the hand support upon closing, and hinders the hand support from closing in a position not aligned with the stick.
  • a hand support for a ski pole assembly comprising an elongated support portion having a back side for supporting the palm of a hand of a user as well as a neck portion extending from an upper end of the elongated support portion.
  • a holder connecting part is located on the neck portion for pivotal connection to a holder such as the holder described herein, such that the hand support is pivotable around a pivot axis of the holder connecting part between a closed position and an open position in relation a connected holder.
  • the pivot axis of the holder connecting part is located at a second forward distance being 2 to 12 cm in a forward direction from the back side of the elongated support portion.
  • the hand support further comprises at least one fastening element arranged at the elongated support portion for engaging with a holding means for holding a hand of a user.
  • the support portion (hereinafter used as abbreviation for elongated support portion) is adapted to be able to support at least a part of the palm of a hand.
  • a hand being fastened to the hand support using the fastening elements is suitably fastened such that the palm of the hand caresses the support portion with the back side against the palm.
  • the support portion may then be held between the thumb and the rest of the fingers, i.e. be gripped.
  • the upper end of the support portion is the end held closer to the index finger than the little finger and the lower end is the other end.
  • the support portion may have different shapes while still fulfilling the same purpose. It may be straight, substantially straight or curved. The transition between the support portion and the neck portion may be rounded or sharply bent. Elongated means that it is longer in one direction, which is the direction which will be denoted as the vertical (upward/downward) direction. In the closed position, these directions, and forward and backward, align well with these directions as used for describing the holder. Downward is for the hand support the direction from the upper end and through the support portion towards the distal end. The horizontal plane is imagined in relation to these directions.
  • the describing directions stay in relation to the hand support and thereby can be imagined as pivoting away from a connected holder and stick; the downward direction of the hand support approaching the backward direction of a connected holder.
  • the forward direction of the hand support is directed away from the palm of the hand, through the back side (and towards a connected stick in the closed position).
  • the support portion ends at an upper end point being on the same vertical level as the intended placement of the upper end of a connected holder. From this point, the neck portion extends.
  • the neck portion extends from the support portion such that the holder connecting part is displaced from the support portion at least in a forward direction. This displacement creates the second forward distance, which is measured as the horizontal distance from the end point of the support portion to the holder connecting part.
  • the forward displacement is necessary to reach the location of a hand support connecting part of a holder, while allowing the support portion stay substantially aligned with a stick.
  • An increased second forward distance increases the distance from the back side of the hand support to a holder and thereby connected stick, which enlarges the grip size.
  • the grip size in this context refers to the grip of a hand around the support portion and the stick. If the back side of the hand support is not made to be located at a distance behind the stick, the grip size would be too small.
  • a alternative partial solution would be to provide the stick with a thicker handle. Here the necessity of this is avoided.
  • a larger forward displacement also provides an increased lever of a pivoting hand, as discussed with regards to the holder.
  • the second forward distance also facilitates incorporation of other features to the hand support, for example a part which is configured to be brought into contact with an upwards directed support surface of the holder in a closed position, such that force of pushing the hand support downwards in the closed position is received by that surface of the holder.
  • the holder connecting part is configured to pivotally connect the hand support to a holder.
  • the connecting parts should be adapted for pivotal engagement with each other.
  • the holder connecting part is suitably located at a distal end of the neck portion.
  • the fastening elements are configured to facilitate the attachment of a holding means to the hand support.
  • the hand of a user has to be fastened to the hand support, not to drop the hand support and pole in an open position.
  • the fastening elements can be located on the back side and be configured in a variety of ways.
  • the pivot axis of the holder connecting part may be located at a second upward distance being up to 6 cm in an upward direction from the end of the back side of the elongated support portion.
  • the upwardly directed second upward distance P2 is calculated from the upper end point of the back side of the support portion, where the extension of the neck portion begins, which is at the same vertical location (i.e. in the same horizontal plane) as the intended location of the upper side of a stick connecting portion of a connected holder.
  • the pivot axis of the holder connecting part and the pivot axis of a hand support connecting part of a holder will coincide when these are connected.
  • the vertical displacement of the pivot axis of the holder connecting part may be adapted to fit the dimensions of a holder to which it is to be connected. In general, as described for the holder, a larger distance increases the lever of a pivoting hand.
  • the neck portion may extend from the upper end of the elongated support portion such that the nearest point on the pivot axis of the holder connecting part extends from the end of the back side of the elongated support portion at an angle being 15-85 °.
  • angles ⁇ and ⁇ are measured from the same vertical position, i.e. the same horizontal plane.
  • the different distance in the horizontal plane from the measuring points of the angles to the pivot axis provides the difference in angles, ⁇ being larger than ⁇ .
  • the angles are mutually adapted in such a way that the back side of the hand support is substantially parallel to a connected stick and at a distance which provides a comfortable hand grip.
  • the hand support may further comprise a spacing part extending from the elongated support portion in a forward direction. It may be configured to abut or almost abut a stick connected to a holder when a holder is connected to the hand support and in the closed position. If it abuts the stick, it helps maintain the distance between the back side of the support portion and a stick. It has an inclination towards the stick that is more forwardly directed than the elongation direction of the support portion. It may extend with a sharp angle or as soft bend from the support portion. It may extend substantially straight forward. It may be configured to maintain the sideways position of the hand support in relation to a stick by comprising a recess, in which the stick lands in the closed position.
  • the hand support may comprise a rigid securing projection extending from an upper half of the elongated support portion, configured to abut a holder or a stick connected to a holder when a holder is connected to the hand support and in the closed position, thereby configured to hinder the hand support from being pressed forward towards the holder leading to disconnection of connecting parts of the hand support and a holder. If the upper part of the hand support is pushed hard towards the holder, the connecting parts could disconnect. The securing projection stops the hand support from being pressed too far forward and such a disconnection from happening.
  • the securing projection, spacing projection and spacing part are designed to maintain a distance between the hand support and the holder/stick or to increase stability or both. If more than one of these are present, they may be mutually adapted to complement each others functions.
  • the neck portion may comprise a forcing part configured to exert an axial force onto a support surface of a holder when the hand support is connected to a holder and is in the closed position and is pushed downwards in the direction of the elongation of the elongated support portion.
  • the elongated support portion may comprise a recess such that a cross section of the support portion is U-shaped, [-shaped, V-shaped or O-shaped, configured to decrease the thickness of the support portion while maintaining stability.
  • This shape of the cross section may apply to the whole of the majority of the elongation of the support portion. This way, less material may be used, without substantially decreasing the sturdiness of the support. It may also facilitate the configuration of fastening means and thereby attachment of holding means. It is understood that these figures describing the shapes are not exact, but represents an approximate shape of the recess.
  • the O-shape may be a circle or square shape.
  • a U-shaped, [-shaped or V-shaped recess allows the possibility of a spacing projection of a holder to enter into the recess when the hand support is going into the closed position.
  • a ski pole assembly comprising a hand support as described herein and a holder as described herein.
  • these may be pivotally connected to one another in order to provide a support for a hand, a pivotal connection of a hand to a pole, a good grip size around a stick, and an increased leveraging of a hand using the assembly to push a pole, while being stable and durable.
  • the closed position of the hand support is when the grip size is as smallest. In this position, in use, the user grips around both the hand support and the stick.
  • the hand support In the open position, the hand support is pivotally moved away from the location of a stick; the lower end of the hand support being moved further away from the stick than the upper end.
  • the opening up of a clenched hand of a user moves the hand support from the closed position towards an open position creating a lever effect.
  • the open position comprises all the positions where the hand support is pivotally moved away from the holder/stick. Positions described as for example slightly open, partly open or fully open are all different versions of an open position.
  • the hand of a user is fastened to the hand support such that the hand support provides a support to at least a part of the palm of the hand of a user in both its closed and open position.
  • the result is that the hand of a user may be fastened to an upper end portion of a stick while allowing a pivoting movement of the hand with respect to the upper end portion, allowing the user to loosen the grip of the hand around the stick at an end phase of a pole-pushing.
  • the support surface of the holder and the forcing part of the hand support are preferably mutually adapted in location and shape to abut when the hand support being pushed down in the closed position, in a way that results in less force being applied to the respective connecting parts.
  • both the holder, the hand support and their connection is symmetrical, such that neither is adapted to be used by a left or right hand.
  • a user may switch the pole they are connected to from left to right.
  • a user does not have to stop and think about which pole to use for which hand. It facilitates replacing just one part of the assembly (if broken) and reduces manufacturing complexity and costs.
  • the parts could be adapted for the left and right hand.
  • the first forward distance and the second forward distance are mutually adapted to provide a grip distance of 1.5-6 cm between the back side of the elongated support portion and the central axis of a stick when a stick is connected to the holder pivotally connected to the hand support and in a closed position, thereby creating an adapted distance from the palm of a hand of a user to the stick and providing a suitable grip size.
  • the holder and hand support may be dimensioned such that the first forward distance is greater than the second forward distance, the difference providing the grip distance between the back side of the support portion and the central axis of a connected stick (to which distance the radius of the stick of the pole is added for the full actual grip size).
  • the dimensions of the holder and hand support are mutually customized for the parts to fit together.
  • the hand support and the holder may each be manufactured by injection moulding. They are thereby easy and cheap to manufacture.
  • a ski pole comprising a stick and the ski pole assembly as described above.
  • a holder 100 for a ski pole assembly comprising
  • the lower end 141 may be configured to be attached to an upper end of a stick 300 by having a recess in which the top of a stick fits.
  • the recess may be shaped such that the stick connecting part 110 mostly is comprised of a surrounding wall and a top wall at least partly enclosing the upper end of the stick 300.
  • the surrounding wall may be circular.
  • the walls may be 1-5 mm thick, preferably 1.5-3 mm thick, such as 2 mm thick.
  • Figure 5 shows a such a protrusion, which in essence is shaped as a circular wall.
  • the protrusion may extend less from the upper end 142 than the surrounding wall, as in figure 5 . It may also instead extend further than the surrounding wall.
  • the lower end 141 may be configured not to enclose the top end of a stick at all, i.e. have no surrounding wall, but only be adapted to protrude into a stick 300.
  • the stick connecting portion 110 may in any case be permanently attached to a stick by being glued to it.
  • Figures 1-5 and 7-11 show a stick connecting portion 110 having a lower end 141 configured to fit on top of a stick, with a recess creating a circular surrounding wall adapted to enclose the upper end of the stick, a top wall and a thin-walled protrusion extending from the top-wall such that it enters into a hollow stick when such is connected.
  • the stick connecting part 110 could be elongated in the upwards direction. Part of a stick 300 could that way be replaced by an elongated stick connecting part 110. However, the intention of the stick connecting part 110 of the invention is not to replace part of the stick 300, but to secure connection to the stick. Prolongation of the stick upward or forward is achieved by the bracket portion 120, which may be integral with the stick connecting part, but differs in shape or direction.
  • the bracket portion 120 in figures 1-5 and 7-11 substantially extends from the upper end 142 of the stick connecting portion 110. It may additionally extend from the sides of the stick connecting portion 110. It is also possible that the bracket portion 120 extends substantially from side portions of the stick connecting portion 110.

  • the direction of the force F is illustrated in figures 1-2 and 6-7 . It may comprise a flat surface orthogonal to the axial force F. It may comprise a surface with a forward inclination. It may comprise a downwards recess. It may comprise an upwards protrusion. It may comprise a creased surface, comprising several recesses and protrusions. It may be located on the stick connecting portion 110. It may be located on the bracket portion 120. It may be located on both. It may be located substantially above the area where a stick will be connected. This way no horizontally extending parts are unnecessarily stressed or at risk of being bent by the force F applied to it.
  • the bracket portion 120 may comprises two side portions 121, 122 divided by a recess. At least a part of the support surface 115 may be positioned between the side portions 121, 122. The support surface may instead or additionally be located on the stick connecting part 110 on areas outside of the bracket portion 120.
  • Figures 1-5 and 7-11 shows a holder having a bracket portion 120 extending at an angle upward and forward from the stick connecting portion 110, the bracket portion having two almost fully separated side portions 121, 122, where the support surface 115 comprises a flat surface orthogonal to the axial force F and is located on the upper end 142 of the stick connecting portion 110, in between the two side portions 121, 122.
