Description

Technical Field

[0001] This invention relates to the field of luggage, and more particularly to a luggage bag for ski equipment. Background Technology

[0002] With the increasing popularity of skiing, ski enthusiasts need to carry heavy and oversized equipment such as skis, ski poles, and helmets over long distances, making luggage and bags essential for transporting this equipment.

[0003] Currently, the most common ski equipment bags on the market are simple tow bags, typically with two wheels and a simple drag strap at the bottom. Users need to bend over and lift one end of the bag, using the wheels to drag it. The drawback of this method is that the user's arms and back must continuously bear a huge torque, making long-distance walking extremely strenuous and prone to fatigue and muscle injury. More importantly, due to the lack of a stable third point of support, the bag cannot stand upright when stationary and is prone to tipping over, potentially damaging expensive equipment inside and causing significant inconvenience to users when checking in at airports, train stations, and other similar locations. Therefore, improvements are needed. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a ski equipment luggage bag.

[0005] The technical solution of the present invention is as follows: a ski equipment luggage bag, characterized in that it includes: a box body and a folding bracket;

[0006] The bottom of the box is provided with a roller on one side and a receiving groove for accommodating the folding bracket on the other side;

[0007] The folding bracket includes a support leg, a button, an elastic element, a transmission element, and a retaining shaft. The support leg is rotatably connected to the housing. The button is disposed on the support leg and can be pressed. The retaining shaft is slidably disposed at one end of the support leg. The transmission element connects the button and the retaining shaft, so that pressing the button can drive the retaining shaft to slide through the transmission element. The elastic element is disposed on the support leg to provide a restoring force for the button.

[0008] The housing is provided with a first slot and a second slot, and the locking shaft can selectively engage with the first slot or the second slot;

[0009] When the locking pin engages with the first locking slot, the folding bracket is locked and fully housed within the receiving slot. When the button is pressed to separate the locking pin from the first locking slot, and the folding bracket is rotated to engage the locking pin with the second locking slot, the folding bracket extends out of the receiving slot, and the housing forms a stable triangular support structure through the rollers and the extended folding bracket.

[0010] Furthermore, the outrigger is an I-shaped outrigger, and the outrigger includes two parallel first frame rods and a second frame rod connecting the two first frame rods.

[0011] The receiving groove is an I-shaped groove, which includes two parallel first grooves and a second groove connected between the two first grooves. The first support rod can be accommodated in the first groove, and the second support rod can be accommodated in the second groove. A rotating shaft is provided in the first groove, and a rotating hole is provided on the first support rod. The rotating hole is rotatably engaged with the rotating shaft.

[0012] Furthermore, both the first and second support poles are hollow and interconnected, so that the legs form an I-shaped cavity inside, and the second support pole is provided with an installation port;

[0013] The transmission component includes a first connecting rod disposed in a first frame and a second connecting rod disposed in a second frame. The first connecting rod and the second connecting rod are fixedly connected and both can slide relative to the support leg. One end of the first connecting rod is provided with the retaining shaft, and the second connecting rod is provided with the button, which extends outward from the mounting port.

[0014] Furthermore, the second support rod is provided with a sliding groove, and the second connecting rod is provided with a guide rail, the guide rail being slidably engaged with the sliding groove.

[0015] Furthermore, the elastic element includes a first spring, which is disposed between the second connecting rod and the second frame rod.

[0016] Furthermore, the elastic element also includes a second spring. One end of the first frame rod is provided with a limiting box. One end of the limiting box is provided with a first through hole, and the other end is provided with a second through hole. The locking shaft is disposed in the limiting box. One end of the locking shaft extends outward from the first through hole to engage with the first locking groove or the second locking groove. The other end of the locking shaft extends outward from the second through hole and is fixedly connected to the first connecting rod. The second spring is disposed in the limiting box and sleeved on the locking shaft.

[0017] Furthermore, the area of ​​the first groove adjacent to the limiting box is provided with an upwardly recessed clearance groove. The upper surface of the clearance groove is an arc surface, the center of which is located on the rotation axis of the folding bracket. The arc surface is provided with the first slot and the second slot.

[0018] The end face of the limiting box with the first through hole is an arc-shaped convex surface. When the folding bracket is rotated, the arc-shaped convex surface slides along the arc surface.

[0019] Furthermore, the second support pole is provided with an elongated clearance hole, through which the rotating shaft passes.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Seamless switching between "integrated storage" and "triangular support": Through the precise cooperation of the storage slot and folding bracket, as well as the unique locking mechanism, users can easily switch between a compact transportation state and a stable triangular support state, perfectly solving the pain points of ski equipment bags being bulky when carried and unstable when parked.

[0022] 2. An innovative "one-button operation" linkage locking mechanism has been developed: the entire operation process (press-rotate-lock) is triggered by a single button. The internally integrated linkage transmission system accurately transmits the operating force. Combined with a dual-spring system (the first spring resets the button, and the second spring presses the locking shaft), it achieves convenient operation, a strong force feedback, and reliable locking, resulting in an excellent user experience.

[0023] 3. The "I-shaped" composite functional structure has been optimized: both the legs and the receiving slot adopt an I-shaped design, which not only gives the bracket extremely high bending strength to withstand heavy loads, but also completely integrates the transmission components through the internal hollow design. While realizing complex functions, it ensures the compactness, aesthetics and simplicity of the structure, and maximizes the structural strength and space utilization.

[0024] 4. Attention to detail in design to enhance durability and smoothness: The arc-shaped convex surface of the limit box and the concentric arc surface of the clearance groove ensure low wear and high stability during rotation; the design of the slide groove and guide rail guarantees the linear motion accuracy of the internal transmission components; the setting of the clearance hole eliminates potential motion interference. These details together ensure the reliability and lifespan of the mechanism under long-term and frequent use.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "inner," "outer," "vertical," "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0041] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] In the description of this invention, "first feature" and "second feature" may include one or more of the indicated features. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of the indicated features.

[0043] Please refer to the attached diagram below. Figures 1-9 A ski equipment luggage bag according to an embodiment of the present invention is described, the bag including a case body 1 and a folding support 2.

[0044] like Figures 1-3 As shown, a roller 12 is provided on one side of the bottom of the case 1, and a receiving groove 11 for accommodating the folding bracket 2 is provided on the opposite side of the roller 12. This layout makes the center of gravity of the case stable when it is dragged, and the folding bracket 2 can be completely hidden, keeping the appearance of the case 1 neat and smooth.

[0045] like Figures 4-9As shown, the folding bracket 2 includes a leg 21, a button 22, an elastic element, a transmission element, and a retaining shaft 25. The leg 21 is rotatably connected to the housing 1 via a pivot 15, allowing the leg 21 to rotate relative to the housing 1. The button 22 is mounted on the leg 21 for user pressing. The retaining shaft 25 is slidably mounted at one end of the leg 21. The transmission element connects the button 22 and the retaining shaft 25, forming a force transmission path, so that pressing the button 22 drives the retaining shaft 25 to slide axially, achieving retraction. The elastic element is mounted on the leg 21 to provide a restoring force after the button 22 is released and to give the retaining shaft 25 a tendency to pop outward.

[0046] like Figures 2-6 As shown, a first slot 13 and a second slot 14 are provided at specific positions on the housing 1, specifically in the receiving groove 11. The locking shaft 25 can selectively engage with either the first slot 13 or the second slot 14, thereby achieving mechanical locking in two stable states.

[0047] When the locking pin 25 engages with the first locking slot 13, the folding bracket 2 is locked and completely stored in the receiving slot 11, making the bag easy to transport and store.

[0048] Pressing button 22 drives the locking shaft 25 through a transmission component, causing it to separate from the first locking slot 13 and unlock. Then, rotating the folding bracket 2 causes it to extend from the receiving slot 11. When rotated to a specific angle, the locking shaft 25 automatically pops out under the action of the elastic element and engages with the second locking slot 14. At this time, the folding bracket 2 is locked in the unfolded position. The case 1, through the bottom rollers 12 and the extended folding bracket 2, forms a stable triangular support structure with the ground, which can reliably support the case 1 containing heavy equipment such as skis, and also facilitates the user to push and pull the case 2 to move it.

[0049] In some implementations, such as Figure 6 and Figure 7 As shown, to optimize structural strength and space utilization, the support leg 21 adopts an I-beam structure, including two parallel first support rods 211 and a second support rod 212 connected between the two first support rods 211. Correspondingly, the receiving groove 11 is also designed as a matching I-beam groove, including two parallel first grooves 111 and a second groove 112 connected between the two first grooves 111. The first support rod 211 can be accommodated in the first groove 111, and the second support rod 212 can be accommodated in the second groove 112. A rotating shaft 15 is provided in the first groove 111, and a rotating hole is provided on the first support rod 211. The rotating hole and the rotating shaft 15 are rotatably engaged, realizing a reliable connection between the support leg 21 and the housing 1.

[0050] In some implementations, such as Figure 8 and Figure 9As shown, in order to achieve the linkage function of "one-button operation" and to keep the appearance neat by embedding all moving parts, the first support rod 211 and the second support rod 212 are both designed to be hollow and interconnected, so that the entire support leg 21 forms a continuous I-shaped cavity. The second support rod 212 is provided with an installation port.

[0051] The transmission components include a first connecting rod 23 disposed within the cavity of the first support rod 211 and a second connecting rod 24 disposed within the cavity of the second support rod 212. The first connecting rod 23 and the second connecting rod 24 are fixedly connected (e.g., by welding or integral molding), and the two can slide relative to the inner wall of the support leg 21 as a whole. One end of the first connecting rod 23 is provided with a retaining pin 25, and the second connecting rod 24 is provided with a button 22, which extends outward from the mounting port for easy user operation.

[0052] In some implementations, such as Figure 9 As shown, in order to ensure the stability of the second link 24 sliding in the cavity of the second frame 212 and to prevent it from deflecting or getting stuck, a groove 213 is provided on the inner wall of the second frame 212, and a matching guide rail 241 is provided on the second link 24. The guide rail 241 and the groove 213 slide together.

[0053] In some embodiments, the elastic element includes a first spring 26. The first spring 26 is disposed between the inner wall of the second connecting rod 24 and the second support rod 212, and its preload provides a reset force for the button 22 and indirectly gives the retaining shaft 25 an initial state that maintains an outward extension tendency.

[0054] In some implementations, such as Figure 8 and Figure 9 As shown, to optimize the engagement feel and reliability of the locking shaft 25, the elastic element also includes a second spring 27. A limiting box 28 is provided at one end of the first support rod 211. One end of the limiting box 28 has a first through hole for the locking shaft 25 to pass through, and the other end has a second through hole. The locking shaft 25 is disposed within the limiting box 28, with one end extending outward from the first through hole to engage with the locking groove, and the other end extending outward from the second through hole and fixedly connected to the end of the first connecting rod 23. The second spring 27 is disposed within the limiting box 28 and sleeved on the locking shaft 25, with its two ends abutting against the inner wall of the limiting box 28 and the shoulder of the locking shaft 25 or the end of the first connecting rod 23, respectively. The second spring 27 directly provides a clamping force to the locking shaft 25 in the direction of the locking groove, ensuring a secure engagement.

[0055] In some implementations, such as Figures 5-7As shown, to ensure smooth rotation of the folding bracket 2 and precise positioning of the slots, an upwardly recessed clearance groove 16 is provided in the area adjacent to the limiting box 28 of the first groove 111. The upper surface of the clearance groove 16 is a carefully designed arc surface, the center of which is precisely located on the rotation axis of the folding bracket 2 (i.e., the center line of the rotating shaft 15). The arc surface is provided with a first slot 13 and a second slot 14. Correspondingly, the end face of the limiting box 28 with the first through hole is an arc-shaped convex surface that matches the arc surface.

[0056] When the folding bracket 2 is rotated, the arc-shaped convex surface slides along the arc surface. This contact design ensures smooth movement and bears the main supporting force. Under the action of the second spring 27, the retaining shaft 25 always tends to press against the arc surface, and automatically engages when rotated to the retaining slot position.

[0057] In some embodiments, to avoid motion interference between the movement of the second support rod 212 and the rotating shaft 15, the second support rod 212 is provided with an elongated clearance hole 231 through which the rotating shaft 15 passes.

[0058] In summary, this ski equipment luggage bag has the following features:

[0059] 1. Seamless switching between "integrated storage" and "triangular support": Through the precise cooperation between the storage slot 11 and the folding bracket 2, as well as the unique locking mechanism, users can easily switch between a compact transportation state and a stable triangular support state, perfectly solving the pain points of ski equipment bags being bulky when carried and unstable when parked.

[0060] 2. An innovative "one-button operation" linkage locking mechanism has been developed: the entire operation process (press-rotate-lock) is triggered by a button 22. The internally integrated linkage transmission system accurately transmits the operating force. Combined with the dual spring system (first spring 26 resets button 22, second spring 27 presses the locking shaft 25), it achieves convenient operation, force feedback, and reliable locking, resulting in an excellent user experience.

[0061] 3. The "I-shaped" composite functional structure has been optimized: Both the support leg 21 and the receiving groove 11 adopt an I-shaped design, which not only gives the bracket extremely high bending strength to withstand heavy loads, but also completely integrates the transmission components through the internal hollow design. While realizing complex functions, it ensures the compactness, aesthetics and simplicity of the structure, and maximizes the structural strength and space utilization.

[0062] 4. Attention to detail in design to enhance durability and smoothness: The arc-shaped convex surface of the limit box 28 and the concentric arc surface of the clearance groove 16 cooperate to ensure low wear and high stability during rotation; the design of the slide groove 213 and guide rail 241 ensures the linear motion accuracy of the internal transmission components; the setting of the clearance hole 231 eliminates potential motion interference. These details together ensure the reliability and lifespan of the mechanism under long-term and frequent use.

[0063] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations of these embodiments without departing from the principles and spirit of the present invention are within the scope of protection of the claims of the present invention.
