Description

Technical Field

[0001] This utility model relates to outdoor equipment, and more particularly to a snowshoe. Background Technology

[0002] Snowshoes are a type of snow gear that distributes body weight by increasing the contact area, preventing the wearer from sinking into deep snow. Traditional snowshoes are made of aluminum alloy or hard plastic with a fixed frame length. Wearers need to choose snowshoes that fit their foot shape and shoe size. These fixed-length snowshoes cannot be adjusted to varying snow depths, potentially causing difficulty in shallow snow or sinking into deep snow. Therefore, some manufacturers have developed adjustable-length snowshoes, such as those published under CN. Patent document 201135164Y discloses an adjustable snowshoe with a sliding adjustment plate at the end of the base plate. However, the adjustment plate is fixed to the base plate by a connecting pin and cannot be disassembled, which increases the overall weight of the snowshoe. In addition, the pivot of the handle is pivotally connected to a pin. By turning the handle, the pivot is pressed against the adjustment plate and the base plate. This fixing method will cause the clamping force of the handle to decrease after long-term use, resulting in the adjustment plate loosening and the connection not being stable enough, making the snowshoe inconvenient to use. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a snowshoe with variable length.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A variable-length snowshoe includes a base plate with straps on both sides for securing the foot. An extension plate is detachably connected to the base plate. Positioning pins for connecting the extension plate are provided on the base plate. Positioning holes for the positioning pins are provided on the extension plate at the connection point with the base plate. After assembly, the base plate and the extension plate have a projection overlap on their vertical projection surfaces. A locking element connecting the base plate and the extension plate is provided on this projection overlap. The base plate and the extension plate are initially connected using positioning pins and a connecting plate. The two are fastened together by locking screws; there is one positioning nail on each side of the base plate, and the positioning nail and locking screw form a stable triangular fixing structure. When the extension plate is subjected to a certain external force, the triangular fixing structure formed by the positioning nail and locking screw can be more stable and it is not easy for relative displacement to occur between the extension plate and the base plate. Compared with the existing method of using a handle to set an eccentric pivot for clamping and fixing, the connection is more stable, and the base plate and extension plate are detachable. When the snow surface is firm enough and the extension plate is not needed, the extension plate can be removed to reduce the weight of the snowshoe and make it more flexible to use.

[0006] The positioning hole includes an insertion part through which the positioning pin passes and a fixing part for clamping the positioning pin. After the head of the positioning pin passes through the insertion part of the positioning hole, the pin shaft of the positioning pin extends into the fixing part of the positioning hole and is clamped and fixed.

[0007] The locking component includes a locking screw and a locking knob.

[0008] The extension plate has a notch on the part that overlaps with the projection of the base plate. The extension plate extends into a connecting plate at the bottom. The locking screw passes through the threaded hole on the base plate and the connecting hole on the connecting plate, and then is threadedly connected to the locking knob to lock and fix the base plate and the extension plate.

[0009] The base plate has a connection port on the part where its projection overlaps with that of the extension plate. The front end of the extension plate has a plug plate. After the plug plate is inserted into the connection port, the top surface of the plug plate abuts against the bottom surface of the base plate. After the extension plate is fixed to the base plate, when the extension plate is subjected to resistance in the vertical direction, the resistance will be transmitted to the positioning pin and locking screw used for connection. In order to distribute the external resistance and prevent the connecting parts from being damaged under the action of external force, the plug plate improves the bending resistance of the snowshoe.

[0010] Two ice skates are symmetrically installed on the bottom surface of the base plate along its extension direction. The ice skates are threaded to the bottom of the base plate and have serrated notches. The ice skates are designed to cut through the snow without fully lifting the foot when walking on the snow, reducing leg resistance and increasing movement speed.

[0011] The front side of the base plate is equipped with a grappling hook to enhance grip. The grappling hook has multiple toothed protrusions arranged perpendicular to the extension direction of the base plate. The toothed protrusions bend towards the front of the snowshoe. When the wearer walks in the snowshoe, the toothed protrusions cut into the snow layer, creating a one-way resistance difference, which helps the wearer walk on the snow.

[0012] Protective covers are fitted on the outside of the ice skates and grappling hooks.

[0013] The front end of the base plate is bent upward to form a raised part. A support member is also hinged to the rear of the base plate. The support member is bent to both sides to form a bent part. The bent part is hinged to the hinge hole of the ice skate. The base plate is provided with a positioning slot hole for the support member to pass through. After the support member is flipped about the hinge hole, it abuts against the hole wall of the positioning slot hole.

[0014] Structural reinforcing ribs are provided in the direction perpendicular to the extension of the base plate.

[0015] The beneficial effects of this utility model are as follows: This utility model features a detachable extension plate at the end of the base plate. The base plate and the extension plate are initially connected using positioning nails and plug-in plates. A locking screw secures the connection at the overlapping portion of the base plate and the extension plate's projections. Compared to the existing method of using a handle with an eccentric pivot for clamping and fixing, this connection is more stable. Furthermore, the base plate and the extension plate are detachable. When the snow surface is sufficiently firm and the extension plate is no longer needed, it can be removed, reducing the weight of the snowshoe and making it more flexible to use. Additionally, this utility model includes a support component. When walking on snow with a certain slope, the support component can be flipped to form an angle with the base plate, making the wearer's feet more horizontal and making climbing easier.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0024] Reference Figures 1 to 5A variable-length snowshoe includes a base plate 1 with straps on both sides for tightening the feet. An extension plate 2 is detachably connected to the base plate 1. Positioning pins 3 for connecting the extension plate 2 are provided on the base plate 1. One positioning pin is provided on each side of the base plate, and the positioning pins and locking screws form a stable triangular fixing structure. When the extension plate is subjected to a certain external force, the triangular fixing structure formed by the positioning pins and locking screws can be more stable and less likely to cause relative displacement between the extension plate and the base plate. The extension plate 2 has positioning holes 20 for the positioning pins 3 to pass through at the connection point with the base plate 1. After assembly, the base plate 1 and the extension plate 2 have a projection overlap on the vertical projection plane. A locking member 4 for connecting the base plate 1 and the extension plate 2 is provided on the projection overlap. The locking member 4 includes a locking screw 40 and a locking knob 41.

[0025] The base plate in this embodiment is sufficient for general snow surfaces and can be adapted to most snow surface conditions for people of average weight. If some wearers are heavier and sink into the snow while wearing only the base plate, an extension plate can be connected to the rear end of the base plate to increase the contact area with the snow surface, reduce the pressure on the snow surface, and prevent the wearer from sinking. Under normal circumstances, the base plate and the extension plate are separate.

[0026] The positioning hole 20 includes an insertion part 200 through which the positioning nail 3 passes and a fixing part 201 for clamping the positioning nail 3. After the nail head of the positioning nail 3 passes through the insertion part 200 of the positioning hole 20, the nail shank of the positioning nail 3 extends into the fixing part 201 of the positioning hole 20 and is clamped and fixed. Compared with the existing method of using a handle with an eccentric pivot for clamping and fixing, this connection is more stable, and the base plate and the extension plate are detachable. The wearer can choose to install or remove the extension plate according to the snow surface. When the snow surface is relatively soft and cannot provide sufficient support, the weight borne by the snow surface remains unchanged. By increasing the support area, the pressure of the snow surface is reduced, so that the wearer will not sink when stepping on a relatively soft snow surface. Conversely, when the snow surface is relatively hard, the extension plate can be removed to reduce the overall weight of the snow boot, making the snow boot more flexible and lightweight to use and improving the movement speed of wearing the snow boot.

[0027] The extension plate 2 has a notch 21 on the part that overlaps with the projection of the base plate 1. The extension plate 2 extends a connecting plate 22 at the bottom. The locking screw 40 passes through the threaded hole on the base plate 1 and the connecting hole on the connecting plate 22, and is threadedly connected to the locking knob 41 to lock and fix the base plate 1 and the extension plate 2.

[0028] The base plate 1 has a connection port 10 on the overlapping part of its projection with the extension plate 2. The front end of the extension plate 2 is provided with a plug plate 23. After the plug plate 23 is inserted into the connection port 10, the top surface of the plug plate 23 abuts against the bottom surface of the base plate 1. After the extension plate is fixed on the base plate, when the extension plate is subjected to resistance in the vertical direction, the resistance will be transmitted to the positioning pin and locking screw used for connection. In order to distribute the external resistance and prevent the connecting parts from being damaged under the action of external force, the plug plate improves the bending resistance of the snowshoe.

[0029] Two ice skates 5 are symmetrically mounted on the bottom surface of the base plate 1 along its extension direction. The ice skates 5 are threaded to the bottom of the base plate 1 and have serrated notches. A protective sleeve 7 is fitted on the outside of the ice skates 5 and the hook 6. The ice skates are designed to cut through the snow without fully lifting the foot when walking on the snow, reducing leg resistance and increasing movement speed. In addition, because the ice skates have serrated notches, the snowshoes are prone to scratching the user when stored. Therefore, to improve the safety of the snowshoes, a protective sleeve is installed on the ice skates in this embodiment. The protective sleeve has a groove in the center to accommodate the ice skate blade. After the snowshoes are used, the ice skates are placed into the groove in the center of the protective sleeve to prevent the ice skates from scratching the user.

[0030] A grappling hook 6 for enhanced grip is installed on the front side of the base plate 1. The grappling hook 6 has multiple toothed protrusions 60 arranged perpendicular to the extension direction of the base plate 1. The toothed protrusions 60 bend towards the front of the snowshoe. In this embodiment, not only are ice skates installed on the bottom surface of the base plate, but also grappling hooks for enhanced grip are installed on the front side of the base plate. The grappling hooks have toothed protrusions that bend forward. When walking on snow, the toothed protrusions insert into the snow layer. When the wearer pushes off the ground with their feet, the back of the toothed protrusions presses against the snow layer to provide support for the wearer. Even if the snow layer is thick, the toothed protrusions of the grappling hook can penetrate deeply into the snow layer, which can improve the grip of the snowshoe and also play a role in preventing slipping.

[0031] The front end of the base plate 1 is bent upward to form a raised part 11. A support member 8 is also hinged to the rear of the base plate 1. The support member 8 is bent to both sides to form a bent part. The bent part is hinged to the hinge hole of the ice skate 5. The base plate 1 is provided with a positioning slot 12 for the support member 8 to pass through. After the support member 8 is flipped about the hinge hole, it abuts against the hole wall of the positioning slot 12. In addition, this embodiment also provides a support member. When walking on a snow surface with a certain slope, the support member is flipped so that it forms an angle with the base plate, so that the wearer's feet tend to be horizontal, making it easier to climb slopes. Using a support member to support the feet and make the soles of the feet more horizontal, which makes it easier for the wearer to climb slopes, is a prior art that has been disclosed, such as the patent document with publication number CN111567982A. Therefore, the specific structure of the support member will not be described in detail in this embodiment.

[0032] The bottom plate 1 is provided with structural reinforcing ribs 13 in the direction perpendicular to its extension. When a user wears snowshoes, the bottom plate is subjected to the user's treads. After prolonged use, the snowshoes are prone to cracking from the center due to prolonged bending, resulting in the snowshoes becoming unusable. In order to improve the overall structural strength of the snowshoes, this embodiment provides transverse structural reinforcing ribs in the vertical direction of the bottom plate extension, which improves the structural strength of the bottom plate, making it more robust and durable, and extending the service life of the snowshoes.
