Description

Technical Field

[0001] This application relates to the field of sports equipment storage technology, and in particular to a racket head separation and fixing device and a racket storage appliance. Background Technology

[0002] High-end rackets are expensive, and their finish and structural integrity directly affect the user experience, lifespan, and resale value. Currently, racket bags on the market generally have the following blind spots in terms of protection: 1. Traditional racket bags' vertical dividers cannot effectively isolate the racket head area: Existing racket bags typically have vertical dividers inside the bag to separate multiple rackets. However, these internal vertical dividers only separate the shafts, leaving the widest and most easily collided area—the racket head—completely exposed. When multiple rackets are mixed together, friction between the racket heads easily leads to paint wear, and even impacts can cause structural damage to the racket frame.

[0003] 2. Full-coverage racket covers are cumbersome to operate and cannot solve the problem of damage between multiple rackets: In order to solve the problem of protecting a single racket, various full-coverage racket covers have appeared on the market. However, after a single racket cover is put into the racket bag, multiple racket covers will still rub and squeeze against each other, failing to solve the problem of damage between multiple rackets at the root.

[0004] 3. Existing design approaches have limitations and fail to fully utilize the structural characteristics of the racket itself: Currently, protective solutions in this field generally revolve around the design concept of "full wrapping" or "full isolation," which implicitly assumes the need to add an additional complete physical barrier to prevent contact between racket bodies. However, the above design approach ignores the inherent structural characteristics of the racket itself: the handle is the thickest part, and the shaft diameter is much smaller than the racket head width—this structural difference could naturally serve as a basis for avoidance and isolation. In fact, when multiple rackets are mixed together, the handle and shaft are naturally less likely to squeeze each other due to their size difference; the actual contact and collision area is concentrated in the widest and most easily displaced part, the racket head. Existing technology fails to recognize this structural characteristic, resulting in redundant protective structure designs (such as wrapping the entire racket) or misplaced protective positions (such as only separating the shaft), failing to achieve the core function of precise isolation of multiple racket heads with the simplest structure.

[0005] Therefore, there is a need for a device that can utilize the structural characteristics of the racket itself to achieve precise isolation of multiple racket heads by simplifying the structure. Summary of the Invention

[0006] The embodiments of this application provide a racket head separation and fixing device and a racket storage device. By precisely fixing and isolating the heads of multiple rackets, the remaining parts of the racket automatically form physical gaps due to their structural differences (thick handle, thin shaft), thereby eliminating the problem of rackets bumping and rubbing against each other in the bag.

[0007] To achieve the above objectives, in a first aspect, embodiments of this application provide a racket head separation and fixing device. The racket includes a racket head, a shaft, and a handle.

[0011] Furthermore, the substrate is an elastic bag; the elastic bag is integrally molded from silicone or TPE elastic material; the racket head receiving and fixing part is a through cavity set in the substrate; the opening width of the through cavity in its natural state is 5~10mm smaller than the width of the racket head, so as to form an elastic groove, so that the racket can be locked after it is inserted.

[0012] Furthermore, the base consists of multiple single-spar sleeve units connected in sequence; each single-spar sleeve unit is a flexible sleeve with an opening at the top that can cover the racket head; the racket head receiving and fixing part is a cavity formed by the single-spar sleeve unit; the opening of the single-spar sleeve unit is provided with a constriction limiting structure; the constriction limiting structure is used to prevent the racket head from coming out of the cavity; two adjacent single-spar sleeve units are detachably connected by connectors provided on the front or rear surface of the single-spar sleeve unit.

[0013] Furthermore, the connector is a Velcro, magnetic snap, snap, or zipper.

[0014] Furthermore, the drawstring limiting structure can be a drawstring drawstring, an elastic band, a Velcro strap, or a snap flap.

[0017] Furthermore, the constraint structure is a pocket or an elastic strap.

[0018] This application has the following advantages over the prior art: 1.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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 this application.

[0031] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can refer to fixed connections, detachable connections, or integral connections; those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] 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 technical features indicated. Thus, a feature defined as "first" or "second" can explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0033] "Racquet" refers to all kinds of sports rackets with a head, shaft / throat and handle, such as badminton rackets, tennis rackets, squash rackets, soft tennis rackets, etc.

[0034] "Racket head receiving and fixing part" refers to any structure that can receive a racket head and keep it in a fixed position relative to the base, while maintaining a distance from other racket heads. Its forms include, but are not limited to: receiving cavity formed by partition plates, slots in elastic materials, claws or straps on the blade, magnetic attraction components, etc.

[0035] There are various ways to "accept", including but not limited to inserting the racket head into the cavity, pushing the racket head into the clamp, snapping the racket head into the slot, and attaching the racket head to the magnetic component. All of these methods fall within the semantics of the word "accept".

[0036] Example 1: Reference Figure 1 and Figure 2 This application provides a racket head separating and fixing device (flexible multi-cavity bag type) for storing a racket including a racket head 510, a shaft 520, and a handle 530. The racket head separating and fixing device includes a base and three independent racket head receiving and fixing parts disposed within the base. The racket head receiving and fixing parts enable the racket heads of multiple rackets to be isolated from each other on the base. In the stored state, the racket handle and shaft are exposed outside the racket head receiving and fixing parts, and an isolation gap is formed between the shafts 520 of two adjacent rackets.

[0037] The flexible bag 100 has a micro-trapezoidal structure as its base. The flexible bag 100 has a double-layer structure, comprising an outer layer 102 and an inner layer 103. The outer layer is made of nylon, polyester fiber, canvas, or neoprene. The inner layer, which contacts the racket head, is made of fleece, short-pile fabric, or a silicone coating. The flexible bag 100 can also be directly sewn from thick, soft fabric.

[0038] The flexible bag 100 has a depth of 280mm along the direction of racket head insertion (based on the common badminton racket head and cone total length of 250~270mm, so that the cone is located at the bag opening, i.e., its height is 1~3cm greater than the total length of the racket head and cone). The width of the opening end is 20~50mm greater than the width of the bottom end, preferably with a total opening width of 160mm and a bottom width of 120mm, forming a slight trapezoid.

[0039] Two partition layers 130 are sewn inside the flexible bag body 100. The two adjacent partition layers 130, together with the bottom wall, left wall, and right wall of the flexible bag body 100, form one of the receiving cavities, namely the beater head receiving and fixing part 110. The receiving cavity at the front end is formed by the partition layer 130 located at the front end and the front wall, left wall, and right wall of the flexible bag body 100. The receiving cavity at the rear end is formed by the other partition layer 130 located at the rear end and the rear wall, left wall, and right wall of the flexible bag body 100.

[0040] The separator layer 130 can be made of double-layered fabric sandwiched with thin sponge, foam or felt, with soft lining on both sides, and a thickness of about 2~5mm.

[0041] The flexible bag body 100 has a drawstring closure structure 140 at its open end 120 to prevent the pat head from coming out. The drawstring closure structure 140 can be a drawstring (with a spring-loaded pig nose buckle), an elastic band, a Velcro strap, or a snap flap.

[0042] In use, the racket head 510 is inserted into any cavity until it touches the bottom, and the retaining structure 140 is tightened to lock the cone. The handles 530 of all three rackets are exposed. Because the outer diameter of the handle 530 area (typically 20-30mm) is much larger than the diameter of the shaft 520 (approximately 7-9mm), whether adjacent handles 530 are against each other or any handle 530 is against another object, a natural gap is formed between the shafts 520 of adjacent rackets due to the larger outer diameter of the handle 530 area. The dimensions of this embodiment can be adjusted for use with other rackets. For example, a tennis racket: the pocket is about 35-40cm deep and the opening is about 28cm wide, with 2-3 cavities, each 9-11cm wide.

[0043] Squash racket: The pocket is about 30-33cm deep and about 20cm wide at the opening. It has 2-3 cavities, each 6-8cm wide.

[0044] Example 2: Reference Figure 3 This application also provides a racket head separation and fixing device (snap-on fixing type). The difference between Embodiment 2 and Embodiment 1 is that the base of Embodiment 2 includes four rigid or semi-rigid plates 200 (such as ABS plates or epoxy plates) and three sets of clamping assemblies 300. The four rigid or semi-rigid plates 200 are equidistantly arranged. The size of the rigid plate 200 can refer to the size of the flexible bag 100 in Embodiment 1. The racket head receiving and fixing part consists of three sets of clamping assemblies 300 connected one-to-one between two adjacent rigid or semi-rigid plates. The two adjacent rigid or semi-rigid plates 200 and the set of clamping assemblies 300 connected between them form the racket head receiving and fixing part.

[0045] The gripper assembly 300 includes three C-shaped grippers 310, which are respectively positioned at the center of the left, right, and bottom edges of two adjacent rigid plates 200. The gripping distance of the C-shaped grippers 310 is adapted to the thickness of the racket head 510 frame (approximately 10-13mm for badminton rackets and approximately 16-22mm for tennis rackets), and their inner walls are also lined with a flexible protective layer made of flocked or silicone. The center-to-center distance of the three sets of gripper assemblies 300 is approximately 80mm, ensuring sufficient spacing between the racket heads.

[0046] In use, simply push the edge of the frame horizontally into the clamps to secure it. Due to the thicker handle, adjacent shafts / throat are automatically separated. This design is highly versatile; different sizes of clamps can be fitted to the same base plate to accommodate various rackets. The clamps can also be replaced with straps, Velcro, or suction cups.

[0047] Example 3: Reference Figure 4 This application also provides a racket head separating and fixing device (one-piece elastic material). The base is a trapezoidal elastic bag 400 that is narrower at the top and wider at the bottom. The elastic bag 400 is injection molded from elastic materials such as silicone and TPE. The racket head receiving and fixing part is a through cavity 410 disposed in the base. There are three through cavities 410. In the natural state, the width of the opening 420 of the three through cavities 410 is 5-10 mm smaller than the width of the racket head 510, so as to form an elastic groove, so that the racket can be locked in place after insertion. This structure is made of soft material, is paint-friendly, and is suitable for mass production.

[0048] Example 4: Reference Figure 5 This application also provides a racket head separating and fixing device (modular detachable assembly type), the base of which is three single racket cover units 600 connected in sequence. Each single racket cover unit 600 is a flexible cover with an opening at the top that can cover the racket head. The racket head receiving and fixing part is a cavity formed by the single racket cover unit. The opening 620 of each single racket cover unit 600 is provided with a constricting structure 140. Two adjacent single racket cover units 600 are detachably connected by a connector 610 provided on the front or rear surface of the single racket cover unit. The connector 610 can be Velcro, magnetic snap, snap, or zipper.

[0049] That is, in this embodiment, each racket head receiving and fixing part is made into an independent sheath unit 600 forming a cavity (for example, a flexible small bag that only accommodates a single racket head, with a drawstring limiting structure 140 at its opening). The back of the single racket sheath unit 600 located in the middle is sewn with the first part of the connector 610 (for example, the hook and loop side), and the front and back are sewn with the second part of the connector 610 (for example, the hook and loop side). The single racket sheath units 600 located at both ends can be sewn with the connector 610 and appropriate parts as needed.

[0050] Users glue the three sheath units together sequentially to quickly assemble them into a single, separate, and fixing device. The size of the clamp can be adjusted to accommodate rackets with different head widths. This solution allows for flexible increases or decreases in capacity, and each unit can be disassembled and stored separately when not in use, which is very convenient. Each sheath unit itself can use the materials and structure of Examples 1 and 3.

[0051] Example 5: Reference Figure 6 This application also provides a racket storage device, including a racket bag 700 and a racket head separator and fixing device connected to the racket bag; the racket head separator and fixing device is the racket head separator and fixing device in embodiment 1. It should be noted that the racket head separator and fixing device can also be any one of embodiments 2 to 4, which will not be described in detail here.

[0052] Example 6: This embodiment of the application also provides a racket storage device, including a racket bag body and multiple single-racket sheath units, such as three, inserted into the racket bag body. Three sets of constraint structures are arranged sequentially along the front-to-back direction inside the racket bag body, and the three sets of single-racket sheath units are inserted into the corresponding constraint structures. The single-racket sheath unit is the single-racket sheath unit 600 from Example 4. The constraint structure is a pocket or elastic strap. Thus, the racket heads housed in the single-racket sheath units remain in contact with each other, and the racket handles are exposed outside the sheath units. This embodiment allows users to use existing single-racket sheaths with this racket bag without the need to purchase additional connectors or integrated multi-cavity devices.

[0053] It should be noted that the number of racket head receiving and fixing parts in all the embodiments mentioned above can also be two or four, depending on the actual working conditions, and is not limited here.

[0054] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
