Description

Technical Field

[0001] This utility model relates to the field of sports equipment auxiliary equipment technology, specifically a tool for supporting and assisting in the movement and transport of the front skis of a snowmobile. Background Technology

[0002] In winter sports and recreational activities, snowmobiles and snowmobiles with skis have always posed a challenge in moving, transporting, and storing equipment in ski resorts, warehouses, and other ground environments due to their large size and weight. Currently, the common practices are to drag them directly on the ground or have multiple people carry them by hand. Dragging them directly is not only extremely strenuous but also severely wears down the expensive wax layer and materials on the skis, shortening the equipment's lifespan; while carrying them by hand is inefficient, requires multiple people to work together, and is prone to safety hazards such as slips and sprains on bare skis.

[0003] Existing technologies include simple brackets or carts that attempt to install wheels on sleds. However, these devices typically have significant drawbacks: First, they generally lack an effective balance adjustment mechanism. Most employ simple, fixed structures that cannot be adjusted according to the specific weight and center of gravity distribution of the sleds. This makes them prone to tilting forward or backward during movement due to instability, potentially causing the sleds to slip and break, posing a significant safety risk. Second, they have poor adaptability. Different brands and models of sleds vary significantly in width, bottom shape (e.g., different arch curvatures), and edge structure. Existing auxiliary tools lack convenient and reliable width and angle adjustment mechanisms, making it difficult to provide stable and close support to the diverse sleds, resulting in limited versatility.

[0004] Therefore, there is an urgent need in this field for a new type of sled support aid that can not only achieve effortless movement and change sliding friction to rolling friction to ensure the stability and safety of the operation process, but also truly become a practical and reliable snow sports equipment aid. Utility Model Content

[0005] In order to solve the problems of the prior art, this utility model provides a sled support auxiliary tool.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a sled support auxiliary tool, including a support mechanism and two rollers rotatably connected to both sides of the support mechanism. The support mechanism includes a main support and two symmetrically arranged support units. Each support unit includes a connecting frame and a side bracket, with the outer end of the side bracket connected to a roller via a roller shaft; The two ends of the main support are connected to one end of each of the two connecting frames via a width adjustment mechanism; The other end of the connecting frame is connected to the inner end of the side bracket via an angle adjustment mechanism; The main support is equipped with a hook for attaching one end of the sled, and the side support is equipped with a support plate for supporting the other end of the sled.

[0007] Preferably, the width adjustment mechanism includes a first connecting plate located at the end of the main support, the first connecting plate having a longitudinal adjustment groove; and a second connecting plate located at one end of the connecting frame, the second connecting plate having a first connecting hole; bolts pass through the longitudinal adjustment groove and the first connecting hole in sequence to fasten the two together.

[0008] Preferably, the angle adjustment mechanism includes a plurality of third connecting holes opened at the other end of the connecting frame, the plurality of third connecting holes being equidistantly distributed along an arc centered on the second connecting hole; it also includes a fifth connecting hole opened at the inner end of the side bracket; a bolt passes through a selected third connecting hole and the fifth connecting hole to fasten the two together.

[0009] Preferably, the connecting frame and the side support are also connected by a fixing connection mechanism, which includes a second connecting hole on the connecting frame and a fourth connecting hole on the side support, and bolts pass through the second connecting hole and the fourth connecting hole to fix the two together.

[0010] Preferably, the top of the support plate is an upward-convex arc or wedge-shaped structure.

[0011] The inside of the hook is covered with a non-slip material layer.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model utilizes a lever mechanism design with the roller axle as the fulcrum, allowing users to easily pry up one end of the snowsled by pressing down on the main support, thus lifting it off the ground. This transforms sliding friction into rolling friction, reducing the physical exertion required for operation and handling. The lever arm is adjusted via an angle adjustment mechanism, ensuring the wheel axle is positioned below the shock-absorbing arm of the front snowsled (i.e., the highest stress point at the front of the snowsled). 2. The width of the entire support mechanism can be flexibly adjusted via a width adjustment mechanism to accommodate sleds of different widths. The arc or wedge-shaped structure at the top of the support plate easily inserts into various complex curved recesses on the bottom of the sled, while the anti-slip material layer on the inside of the hook increases friction with the edge of the sled. This combination effectively solves the problem of stable fit with sleds of different specifications and shapes, offering strong versatility. 3. This tool lifts the skis off the ground, completely avoiding direct dragging and sliding friction on hard surfaces, thus preventing wear and tear on the wax layer and material of the skis. It also reduces the risk of deformation or damage to the skis due to bumps and impacts during transport and movement. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-4 The sled support aid shown includes a support mechanism and two rollers 4 rotatably connected to both sides of the support mechanism. The support mechanism includes a main support 1 and two symmetrically arranged support units. Each support unit includes a connecting frame 2 and a side bracket 3. The outer end of the side bracket 3 is connected to the roller 4 via a roller shaft 32. The two ends of the main support 1 are respectively connected to one end of the two connecting frames 2 through a width adjustment mechanism; The other end of the connecting frame 2 is connected to the inner end of the side bracket 3 through an angle adjustment mechanism; The main support 1 is provided with a hook 11 for attaching to the upper side of one end of the sled, and the side support 3 is provided with a support plate 31 for supporting the lower side of the other end of the sled.

[0020] The width adjustment mechanism includes a first connecting plate 12 located at one end of the main support 1, on which a longitudinal adjustment groove 121 is provided; it also includes a second connecting plate 21 located at one end of the connecting frame 2, on which a first connecting hole 211 is provided; bolts pass through the longitudinal adjustment groove 121 and the first connecting hole 211 in sequence to fasten the two together.

[0021] The angle adjustment mechanism includes a plurality of third connecting holes 23 opened at the other end of the connecting frame 2, the plurality of third connecting holes 23 being equidistantly distributed along an arc centered on the second connecting hole 22; it also includes a fifth connecting hole 34 opened at the inner end of the side bracket 3; a bolt passes through a selected third connecting hole 23 and the fifth connecting hole 34 to fasten the two together.

[0022] The connecting frame 2 and the side support 3 are also connected by a fixed connection mechanism, which includes a second connecting hole 22 on the connecting frame 2 and a fourth connecting hole 33 on the side support 3. Bolts pass through the second connecting hole 22 and the fourth connecting hole 33 to fix the two together.

[0023] The top of the support plate 31 is an upward-convex arc or wedge-shaped structure.

[0024] The inside of hook 11 is covered with a layer of anti-slip material.

[0025] The installation, adjustment and use steps of this utility model are as follows: I. Assembly and Preliminary Adjustment 1. Component Preparation: The main bracket 1, connecting bracket 2, and side bracket 3 can be made of high-strength 304 or 316 stainless steel sheet through laser cutting and sheet metal bending to ensure sufficient structural strength and lightweight. The rollers 4 can be made of polyurethane or wear-resistant rubber to provide good grip and quiet operation. Also prepare bolts, nuts, and washers of the required specifications.

[0026] 2. Install the rollers: Place the two rollers 4 onto the roller shafts 32 on the outside of the two side brackets 3 respectively, and ensure that they rotate freely without jamming.

[0027] 3. Connecting the side bracket and the connecting frame: Align the connecting frame 2 with the fourth connecting hole 33 on the side bracket 3 through the second connecting hole 22 on it, and use bolts and nuts for initial tightening. At this time, the components on both sides should remain symmetrical.

[0028] II. Key Adjustment Steps to Achieve Balance and Adaptation 1. Width Adjustment and Initial Fit: Align the second connecting plate 21 at the front end of the connecting frame 2 with the first connecting plates 12 at both ends of the main support 1. Based on the estimated width of the sled to be supported, move the second connecting plate 21 so that its first connecting hole 211 selects a suitable horizontal position in the longitudinal adjustment groove 121 of the first connecting plate 12. Then, insert bolts and tighten them. This step initially determines the total width of the support mechanism, making it basically match the width of the sled.

[0029] 2. Angle Adjustment and Core Balance Adjustment: This step is crucial for achieving lever balance. Slightly loosen the bolts that have been initially tightened between the connecting bracket 2 and the side bracket 3. Using the connection point of the second connecting hole 22 and the fourth connecting hole 33 as an axis, rotate the side bracket 3 so that its fifth connecting hole 34 aligns with one of the multiple third connecting holes 23 on the connecting bracket 2.

[0030] Adjustment principle: Selecting different third connecting holes 23 essentially changes the angle and position of the side support 3, including the support plate 31, relative to the fulcrum of the roller shaft 32, thus changing the lever arm. Usually, when the skis are heavy, one end of the support plate 31 needs to be adjusted further back to select a more rearward hole position to increase the lever arm and achieve effortless balance.

[0031] Preliminary test: Manually simulate pressing down on the main support 1 to feel the required force and balance trend, thereby determining whether the angle selection is appropriate. After selection, use bolts to securely connect the fifth connecting hole 34 to the selected third connecting hole 23. Finally, be sure to retighten the connecting bolts of the second connecting hole 22 and the fourth connecting hole 33 to ensure the overall structural rigidity.

[0032] III. Installation onto the skis and final fine-tuning 1. Installation procedure: a. Push the adjusted support tool under the skis.

[0033] b. Insert the support plate 31 on the inner side of the side bracket 3 with its wedge-shaped top end into and press it against a suitable position at the bottom of one end of the sled board, such as the recess of the board or below the edge.

[0034] c. Snap the hook 11 at the front end of the main support 1 into the edge of the top side of the other end of the sled, and use the anti-slip layer on its inner side to increase friction and prevent it from falling off.

[0035] 2. Balance fine-tuning: After completing the initial installation, slowly release your hands and observe the condition of the skis.

[0036] If one end of the hook 11 at the front of the sled suddenly sinks, it indicates that the torque is too large. One end of the support plate 31 needs to be slightly adjusted backward to select the third connecting hole 23 further back, or one end of the hook 11 needs to be slightly adjusted forward to move the connecting frame 2 forward in the longitudinal adjustment groove 121.

[0037] If the rear end of the sled, i.e., one end of the support plate 31, suddenly sinks, then make the opposite adjustment.

[0038] The ultimate goal is to enable the skis to remain in a hovering state without continuous force after being lifted, indicating that the center of gravity has been roughly adjusted to the fulcrum (above the roller axle 32, achieving approximate balance).

[0039] IV. Use and Maintenance 1. Movement: Once balanced, the user only needs to apply a horizontal thrust to the main support 1 to easily move the entire device along with the sled. After the horizontal thrust is decomposed, part of it is used to overcome rolling friction to drive the roller 4 forward, and the other part is used to maintain the balance of the lever system.

[0040] 2. Maintenance: Regularly check that all connecting bolts are tight, the wear of roller 4, and the condition of the anti-slip layer on hook 11. Clean mud and snow from moving parts promptly to ensure smooth operation and safety.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
