Embodiments herein relate to a snowshoe binding. Embodiments herein further relate to a snowshoe comprising a binding.
Snowshoes have been used for a long time, and the design enables persons to move over areas covered with large quantities of snow.
A snowshoe generally comprises a lattice and a binding for fixating the lattice to a boot of a user. The lattice has a relatively large surface or lift area which may prevent sinking of the snowshoe and its user through the snow. It may have several gripping portions which prevent the lattice to slide horizontally on packed snow or ice. The lattice or lifting area may be more or less rigid, or it can be designed with a circumferential frame onto which a canvas or piece of cloth is stretched.
An example of a rigid snowshoe is shown in USD424644 and an example of a frame based snowshoe is shown in US 2003101623A1.
The binding is commonly attached to an upper surface of the lifting area and can comprise a pivoting arrangement. A user may attach a boot to the pivoting arrangement, wherefore the entire snowshoe may pivot relatively the boot. This facilitates walking with the snowshoes. The binding also often comprises a strap, wire or other fixation device which extends around the boot.
While known snowshoe bindings have been working well in some applications, there remains a need for a snowshoe binding which provides for great flexibility and easiness to use. There also remains a need for a snowshoe binding and snowshoe with good manoeuvrable characteristics. Thus, improvements in the field of snowshoe bindings and snowshoes are still desirable.
Embodiments herein aim to provide a snowshoe binding, eliminating or at least reducing the problems and/or drawbacks associated with prior art solutions.
According to an embodiment, this is provided by a snowshoe binding arranged for securing a boot to a snowshoe, the binding comprising a base part which comprises a first part which is arranged to be mounted onto the snowshoe, a second part which is arranged to receive a boot toe portion and a third part which is arranged to receive a flexible heel strap. The binding also comprises a flexible heel strap with a first portion, a second portion and an intermediate portion which extends between the first portion and the second portion. The third part of the base part comprises a first attachment portion for releasable attachment of the first portion of the flexible heel strap and a second attachment portion for releasable attachment of the second portion of the flexible heel strap or a buckle arrangement.
This enables flexible and secure attachment of the first portion of the flexible heel strap to the first attachment portion. The first portion may be one end of the flexible heel strap, an area in close vicinity to one end of the flexible heel strap, or an area at a distance from an end of the flexible heel strap. The first portion of the flexible heel strap may be fully released from the base part, i.e. such that the flexible heel strap is no longer in contact, directly or indirectly, with the third part of the base part. This also enables flexible and secure attachment of the second portion of the flexible heel strap to the second attachment portion. The second portion may be one end of the flexible heel strap, an area in close vicinity to one end of the flexible heel strap, or an area at a distance from an end of the flexible heel strap. The second portion of the flexible heel strap may be fully released from the base part, i.e. such that the flexible heel strap is no longer in contact, directly or indirectly, with the third part of the base part. If the flexible heel strap comprises a buckle arrangement, the flexible heel strap can be totally released from the base part without opening/release of the buckle arrangement.
The binding according to embodiments described herein are made to be used during wearing conditions, for example during long walks over snowy areas and mountains, and in military applications where demands on the equipment may be high. With a flexible heel strap that is releasable from both its attachment areas of the binding, it is easy and quickly done to change the flexible heel strap if it is damaged or worn. The flexible heel strap may also be detached, rotated 180 degrees and attached again. This allows a user to decide how the flexible heel strap should be fitted, which is an advantage if the flexible heel strap is assymetric, has a grip portion in one end or if it comprises a buckle.
Accordingly, the flexible heel strap is arranged to be attached and detached from the first and second attachment portions without tools. This is very useful if the flexible heel strap must be replaced where no tools are available.
Thus, hereby is provided a snowshoe binding, eliminating or at least reducing the problems and/or drawbacks associated with prior art solutions.
According to some embodiments the first attachment portion comprises at least one first attachment portion protrusion and the second attachment portion comprises at least one second attachment portion protrusion. This enables flexible and secure positioning and fastening of the flexible heel strap to both the first attachment portion and the second attachment portion. This also allows the flexible heel strap to be attached and detached in a tool-free manner. Thus, a user may attach or detach the flexible heel strap with his/her bare hands, or with gloves on.
According to some embodiments the first attachment portion comprises at least two first attachment portion protrusions and the second attachment portion comprises at least two second attachment portion protrusions. This enables a more secure positioning and fastening of the flexible heel strap to both the first attachment portion and the second attachment portion. This also allows the flexible heel strap to be attached and detached in a tool-free manner. Thus, a user may attach or detach the flexible heel strap with his/her bare hands, or with gloves on.
According to some embodiments the first attachment portion comprises at least three first attachment portion protrusions and the second attachment portion comprises at least three second attachment portion protrusions. This enables an even more secure positioning and fastening of the flexible heel strap to both the first attachment portion and the second attachment portion. This also allows the flexible heel strap to be attached and detached in a tool-free manner.
According to some embodiments the at least two or three first attachment portion protrusions intersect a first common plane and the at least two or three second attachment portion protrusions intersect a second common plane. Hereby a very robust attachment of a flexible heel strap portion which extends in the first common plane is achieved. Further, a very robust attachment of a flexible heel strap portion which extends in the second common plane is achieved. The protrusions can efficiently withstand forces acting on the flexible heel strap, i.e. forces substantially directed within the first common plane and/or the second common plane. The at least two or three first attachment portion protrusions may extend substantially perpendicular to the first common plane, and they may be directed in the same direction or opposite to each other. The at least two or three second attachment portion protrusions may extend substantially perpendicular to the second common plane, and they may be directed in the same direction or opposite to each other. The first common plane and the second common plane may be flat or slightly curved.
According to some embodiments the first attachment portion comprises a first channel for receiving the first portion of the flexible heel strap, and wherein the second attachment portion comprises a second channel for receiving the second portion of the flexible heel strap. Hereby the flexible heel strap can be inserted into and locked by the channels, which may be arranged with protrusions or other locking organs.
According to some embodiments the flexible heel strap comprises a buckle arrangement for releasable attachment of the flexible heel strap to the second attachment portion. The buckle arrangement can be arranged along the intermediate portion of the flexible heel strap and allows for quick and easy adjustment. The flexible heel strap can be composed of two different parts which can be connected via the buckle arrangement. The buckle arrangement can then position the two different parts relatively each other, such that a length of the flexible heel strap between the first and second attachment portions of the base part can be adjusted. The flexible heel strap can alternatively be arranged as one single part, where the buckle arrangement is in contact with different portions of the flexible heel strap such that a length of the flexible heel strap between the first and second attachment portions of the base part can be adjusted.
In some embodiments herein, the flexible heel strap does not comprise any buckle arrangement at all. A length of the flexible heel strap between the first and second attachment portions of the base part can then be adjusted by selection of which apertures of the flexible heel strap that is attached to the protrusions of the first and/or second attachment portions.
According to some embodiments the intermediate portion of the flexible heel strap comprises a plurality of apertures for engagement to protrusions of the first attachment portion, the second attachment portion and/or at least one protrusion of a buckle arrangement. This enables flexible and secure positioning and fastening of the flexible heel strap.
According to some embodiments the plurality of apertures are indicative of a respective boot size, for enabling pre-adjustment of the snowshoe binding. This enables for a user, or for different user of the same binding, to always have the heel cap at the right position for receiving the boot heel portion independently of boot size. The indication may be alphanumeric, based on colors, different surfaces or similar.
According to some embodiments the base part comprises a third attachment portion and a fourth attachment portion, arranged for releasable attachment of a flexible top strap. The third attachment portion and the fourth attachment portion are arranged for releasable attachment of the flexible top strap in a quick, intuitive and secure manner. The design of the flexible top strap may resemble of the design of the flexible heel strap, and it may comprise apertures which can be snapped onto protrusions of the third attachment portion and a fourth attachment portion. It may or may not be provided with a buckle. With a flexible top strap that is releasable from both its attachment areas of the binding, it is easy and quickly done to change the flexible top strap if it is damaged or worn. The flexible top strap may also be detached, rotated 180 degrees and attached again. This allows a user to decide how the flexible top strap should be fitted, which is an advantage if the flexible top strap is assymetric, has a grip portion in one end or if it comprises a buckle. The design of the flexible top strap may be identical or similar to the flexible heel strap, such that a flexible heel strap may be used between the third attachment portion and the fourth attachment portion, and such that a flexible top strap may be used between the first and second attachment portions.
According to an embodiments there is provided a snowshoe binding arranged for securing a boot to a snowshoe, the binding comprising a base part which comprises a first part which is arranged to be mounted onto the snowshoe, a second part which is arranged to receive a boot toe portion and a third part which is arranged to receive a flexible heel strap, a flexible heel strap with a first portion, a second portion and an intermediate portion which extends between the first portion and the second portion, wherein the third part of the base part comprises a first attachment portion for releasable attachment of the first portion of the flexible heel strap, and wherein the first attachment portion comprises at least one first attachment portion protrusion.

Disclosed features of example embodiments may be combined as readily understood by one of ordinary skill in the art to which this application belongs. Like numbers refer to like elements throughout.
Well-known functions or constructions will not necessarily be described in detail for brevity and/or clarity.
Spatial orientations, such as front/forward, back/rearwards, up/upwards, down/downwards, left and right are indicating directions of the binding and its different parts in a normal operating position, i.e. when the binding is mounted on a snowshoe laying on a substantial horizontal surface. These directions are indicated in
The base part 10 comprises a second part 12 which is arranged to receive a boot toe portion. The second part 12 may project upwards from the relative flat first part 11, thereby allowing the boot toe portion to rest against the second part 12. A top part may be permanently or releasably attached to the first part 11 via one or more attachment portions 12b.
As illustrated in
The base part 10 further comprises a third part 13 which is arranged to receive the flexible heel strap 20, shown in
As illustrated, the third part 13 may protrude upwards from peripheral portions of the first part 11, such that they become arranged on a right and left side of a boot when the boot is inserted into the binding.
The first attachment portion 13a and the second attachment portion 13b may be substantially identical but mirrored. Thus, the left side of the binding 1 may be substantially identical but inverted or reversed to the right side. An advantage with this design is that the same snowshoe binding 1 may be used both for a left snowshoe and a right snowshoe. Also the snowshoes may be identical. Accordingly, a snowshoe with a mounted binding 1 may be used as desired on right or left boot. The flexible heel strap may be totally detached from the attachment portions 13a and 13b, turned 180 degrees and be attached again. Hereby a user may freely select to which foot/boot the binding should be attached. He/she may also freely select if a buckle arrangement should be positioned on the inside of the foot/boot, towards the sagittal plane of the user or on the outside of the foot/boot, facing away from the sagittal plane of the user.
The first attachment portion 13a may comprise at least one first protrusion 13a′ for engagement to a selected one of said plurality of apertures 24. The first portion 21 of the flexible heel strap may be bent and inserted from a rearward direction into a channel of the first attachment portion 13a. When the flexible heel strap 20 is straightened, the aperture or apertures 24 snaps onto the protrusion or protrusions 13a′, 13a″, 13a″′ such that the flexible heel strap is locked in position.
The second attachment portion 13b may comprise at least one second protrusion 13b′ (shown in
The base part 10 may further comprise a third attachment portion 14a and a fourth attachment portion 14b, arranged for releasable attachment of a flexible top strap 40. The design of the flexible top strap 40 in shown in
The third attachment portion 14a may comprise e.g. one, two or three protrusions 14a′, 14a″, 14a″′. The protrusions 14a′, 14a″, 14a″′ may extent is the same or in opposite direction relatively each other. The fourth attachment portion 14b may comprise e.g. one, two or three protrusions 14b′, 14b″, 14b″′. The protrusions 14b′, 14b″, 14b″′ may extent is the same or in opposite direction relatively each other.
The flexible top strap 40 illustrated in
As shown in
The flexible heel strap 20 may be made of any suitable material, such as plastics or nylon. The second portion 22 of the flexible heel strap 20 may comprise a heel strap grip portion 22a, which facilitates for a user to fasten the flexible heel strap 20. The first portion 21 of the flexible heel strap 20 may be relatively uniform in height and thickness, so it can be inserted into the channel from rear. Thus, it does not comprise any protrusions, grip portions or similar. Hereby the entire flexible heel strap 20 may be attached and detached as one unit, also when it is provided with a buckle arrangement along its length. As mentioned, it comprises a plurality of apertures 24 which allows the flexible heel strap to be snapped on protrusions of the base part, and which allows a heel cap protrusion 33 to be snapped into an aperture, thereby positioning the heel cap 33 in a desired position along the length of the flexible heel strap 20.
In some embodiments, the flexible heel strap 20 is made of two different parts where a first part with the first portion 21 is attachable to the first attachment portion 13a and the second part with the second portion 22 is attachable to the second attachment portion 13b. The two parts are then connectable to each other via the buckle arrangement 25 or any other kind of attachment. In some embodiments the second part with the second portion 22 is attached to the buckle arrangement 25 in a releasable manner. In some embodiments the second part with the second portion 22 is permanently attached to the buckle arrangement 25 such that they together form a unit. The second portion 22 of such a unit is arranged to be inserted from a rear direction into channel C2 of the second attachment portion 13b.
In the attached state, entire second portion 22, or substantially the entire second portion 22 is comprised in the channel C2. The inserted end of the unit with the second portion 22 and the buckle arrangement is inserted in a meandering or tortouros manner, in a similar or corresponding manner as shown for the first portion 21 in
The inserted end of the unit with the second portion 22 and the buckle arrangement is thus locked by the boot of the user when the boot is arranged within the binding, in a similar or corresponding manner as shown for the first portion 21 in
In the embodiment illustrated in
The base part 10 may further comprise a third attachment portion 14a and a fourth attachment portion 14b, arranged for releasable attachment of a flexible top strap 40.

Thanks to this, a very secure attachment of the flexible heel strap 20 is achieved, and when needed the flexible heel strap 20 easily can be fully detached without tools. A user may then bend the end 21 out from the channel C1, into the opening C1c, and then continue to release the next aperture 24 from the projection 13a″, then the next aperture from the projection 13a′. When a boot is arranged next to and inside of the first attachment portion 13a the end 21 cannot be bent out from the channel C1, into the opening C1c. Further, since the protrusions extends substantially perpendicular to the flexible heel strap 20, and accordingly substantially perpendicular to forces acting on the flexible heel strap 20 (for example from a boot heel), the attachment is very secure.
The snowshoe S may be made of a strong, durable material such as plastics, and some parts and details may be made of metal. Grip organs S10 may protrudes downwards for increased grip when the snowshoe is used on snow, crust and ice. Some grip organs may be made in metal, and may be attached under the snowshoe and/or base part 10.
The snowshoe S may comprise a heel lifter S20 which may be arranged in different positions for providing support to boot, for example when a user climbs uphill.
As illustrated in e.g.
The flexible top strap 40 with its buckle arrangement may be a self-contained top unit which can be attached to attachment portions 14a and 14b without tools.
Since no buckle is attached to the base part, it is very easy to repair the binding if a buckle becomes broken or defect, since it is only to replace the self-contained unit.
Further, a self-contained top unit may be used as a self-contained heel unit and vice versa.
Thanks to the apertures and the attachment portions, a length of the flexible heel strap 20 between the position of the attached heel cap 30 and the first attachment portion 13a can be freely selected. Thanks to the apertures, the attachment portions and possibly a buckle arrangement 25, a length of the flexible heel strap 20 between the position of the attached heel cap 30 and the second attachment portion 13b can be freely selected.
The heel cap 30 can therefore, at a selected position along the flexible heel strap, be arranged to restrict lateral displacement of a boot heel portion B2, i.e. to fix or position the boot heel portion B2 in a side-to-side or left-right direction.
