Description

Technical Field

[0001] This invention relates to the field of sports equipment and antique decoration manufacturing technology, specifically to an assembly method for a modular sports shield that combines wall decoration and security functions. Background Technology

[0002] As a historically significant handheld protective device, the shield has traditionally been made of materials such as metal, wood, and leather, primarily for military defense. Today, its applications have expanded to cultural displays, film props, and especially the increasingly popular recreational ancient combat sports. These modern applications place complex demands on shields that differ from their traditional military uses: First, in sports, shields must possess sufficient protective strength to withstand high-frequency impacts from weapons or full armor, while also being lightweight and ergonomically designed (e.g., a scientifically positioned grip and cushioning) to ensure user flexibility and comfort, preventing sports injuries. Second, in cultural displays and decorative settings, their form, materials, and craftsmanship must possess a high degree of historical accuracy and visual appeal. Furthermore, users expect the equipment to be easily switchable between various modes, including practical sports use and decorative display.

[0003] Currently, many products on the market fail to meet these diverse needs. For example, shields designed for theatrical props may have a retro appearance, but their structural strength is insufficient to withstand the impact of real combat sports. Shields specifically made for sports often prioritize functionality over historical texture and aesthetic details, and their limited functionality makes them unsuitable for contextual applications such as wall decorations. In terms of manufacturing processes, traditional methods rely heavily on integral molding or non-standard handcrafting, resulting in low production efficiency, poor product consistency, and easy damage to critical parts such as edges and handles over long-term use.

[0004] To address the aforementioned issues, a standardized and modular assembly method was designed to manufacture sports shields that simultaneously meet the requirements of historical accuracy, sports functionality, multi-scenario adaptability, and long-term durability, thereby resolving the technical problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an assembly method for a modular sports shield that combines wall decoration and security functions, thus solving the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An assembly method for a modular sports shield that combines wall decoration and security functions, comprising the following steps: S1: Substrate molding module assembly: Selecting high-strength, lightweight, and tough fir or linden wood as the substrate, controlling its moisture content between 8% and 12%; after cutting the substrate, placing it in a customized arc-shaped mold, and hot-pressing it for 20-30 minutes at a temperature of 120-150℃ and a pressure of 0.8-1.2MPa to form a shield with an inner diameter of 100cm. A cylindrical, curved wooden base layer; the hot-pressed wooden base layer is sanded to ensure a uniform thickness of 9-14mm; S2: Skin / Fabric Module Assembly: 1-2mm thick canvas or top-grain leather is selected as the skin material; an epoxy resin adhesive with a thickness of 0.3-0.5mm is evenly applied to the front, sides, and partially reversed surfaces of the wooden base layer; the cut skin material is then placed over the adhesive-coated area, air is removed, and after the epoxy resin adhesive has partially cured, a spacing of 2.5-3.5mm is used. S3: S1: Cowhide edging module assembly: Select vegetable-tanned cowhide with a thickness of 2-3mm and cut it into edging materials with a width of 5-7cm; attach the edging material to the edge of the wooden base layer and sew it in place using a double S-shaped stitching process, with a stitch spacing of 2-3cm; S4: Grip system module assembly: Determine the installation position of the grip according to the final shape of the shield, and drill holes at preset positions on the reverse side of the wooden base layer; set a thickness of [missing information] between the contact surface of the grip and the wooden base layer.

[0007] Preferably, in step S1, the curvature of the mold used in the hot pressing molding is based on the shape of the shield in the history of traditional European martial arts, so that the curvature of the formed wooden base layer is ergonomic and can effectively dissipate force.

[0008] Preferably, in step S3, the specific steps of the double S-shaped stitching process are as follows: starting from the inside of one end of the edge material, the first needle goes out along the edge to the outside, and the second needle goes in from the outside to the inside in the opposite direction to form an S-shaped trajectory. Subsequent needles repeat this trajectory and maintain a spacing of 2-3 cm.

[0009] Preferably, in step S3, the corners of the edge binding material are treated with a 45° beveled edge folding and pressing process; the joints are connected by overlapping 1-1.5cm.

[0010] Preferably, in step S4, the installation position of the grip is customized according to the shield shape: for a shield with a width of 30-40 cm, the grip is centered and aligned with the central axis of the shield; For shields 50-65 cm in length, the grip should be positioned at the upper 1 / 3 of the longitudinal center line of the shield and tilted counterclockwise at 20 degrees, or at the 1 / 2 point and tilted counterclockwise at 45 degrees. For shields with a length of 65-120 cm, the grip is located at the upper 1 / 3 of the center line between the upper and lower bottom and tilted counterclockwise at 20 degrees; the grip is 20-30 cm long and 2.5-3.5 cm wide, and its structure is an original arc design that fits the curvature of the palm.

[0011] Preferably, in step S4, the adjustable belt system includes a belt with a length of 40cm and a belt with a length of 100-120cm, which are respectively set at different positions on the back of the shield. The length is adjusted by the buckle to realize the function of hanging on the wall or carrying on the back.

[0012] Preferably, in step S6, the wall-mounting stability test involves hanging the shield on a standard wall with a load-bearing capacity of ≥5kg using a D-ring, leaving it stationary for 24 hours, and observing its levelness, belt deformation, and the firmness of the D-ring; the combat strength simulation test involves using a 2kg impact hammer to vertically impact the center and edge of the shield surface from a height of 1m 10 times each, checking the integrity of the shield structure; the grip comfort test involves multiple testers holding the shield continuously for 30 minutes and then rating the comfort level, requiring an average score of ≥8.5 points; the historical consistency test involves comparing historical documents with physical materials, requiring a matching degree of ≥90% in shape, material, and pattern.

[0025] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0026] Example: The structure is particularly suitable for sports such as historical martial arts HEMA, weapon fighting, and full armor combat, while also serving a decorative display function.

[0027] The modular shield comprises three core components: the shield body 1, the modular multi-functional grip system 2 located on the back of the shield body 1, and the interchangeable appearance modules 3 located on the front of the shield body 1.

[0028] The shield body 1 is historically shaped like a hot iron, also known as a kite shape. Its specific dimensions are: 52cm at its widest point, 70cm in total height, 28cm at the top, and 35cm at the bottom. This body is constructed from five layers of 1.5mm thick linden wood sheets laid in a crisscross pattern, hot-pressed in a custom steel mold at 125℃ and 1.0MPa pressure for 25 minutes, forming a convex arc-shaped shell with a radius of curvature of 120cm. Its structure has been optimized: the central area is 12mm thick, transitioning evenly to 8mm thickness towards the edges, ensuring structural strength while achieving effective weight reduction. The edges of the shield body 1 are rounded with an R3 radius, and the side curvature seamlessly connects with the front skin.

[0029] The interchangeable appearance module 3 includes a base layer and a decorative layer. The base layer is made of 1.2mm thick black washed canvas, uniformly coated with epoxy resin AB glue to a thickness of 0.4mm, and completely bonded to the front and side edges of the shield body 1 through a vacuum pressing process. The decorative layer is a "flying eagle and castle" heraldic pattern hand-painted with special acrylic paint. The center of the pattern is located 25cm from the top on the longitudinal central axis of the shield surface, and the overall size of the pattern is 40cm×45cm. It should be noted that the color scheme, composition proportions, and details of this heraldic pattern are completely identical to the views published in the design patent shield of the patentee. The edges of the appearance module 3 are reinforced with double-row stitching, with the stitches 15mm from the edge and a stitch spacing of 2-3cm.

[0030] The modular multi-functional grip system 2 is fixed to the back of the shield body 1 via stainless steel connectors. Its installation position is ergonomically optimized: the system's center of gravity is located 38cm from the top of the shield body's longitudinal central axis. The system specifically includes the following components: The gripping belt 21 consists of two vegetable-tanned cowhide belts, each 32mm wide and 3.5mm thick. Belt A is 280mm long, and belt B is 265mm long. They are arranged at a 58° angle, with the intersection point 35cm vertically from the top of the shield. Each end of the belt is secured with two 5mm diameter stainless steel rivets spaced 45mm apart.

[0031] The adjustable strap 22 is a 480mm long vegetable-tanned cowhide belt of the same specification. One end of it is connected to the right side of the "X" shaped main grip structure via a 30mm×15mm brass buckle. The other end is provided with 5 equally spaced adjustment holes with a diameter of 6mm and a spacing of 15mm.

[0032] The cushioning pad 4 is made of closed-cell foam with a density of 45 kg / m³. 3 With a density of 70kg / m³, slow rebound memory foam 3It is a composite material with an overall thickness of 12mm. Its shape matches the 160mm×140mm area enclosed by the "X"-shaped grip structure, and its edges are chamfered at 45°. The cushioning pad is bonded to the shield body with food-contact pressure-sensitive adhesive.

[0033] The additional mounting point 23 includes two symmetrically arranged mounting units, located at the lower left corner of the shield's back, 60mm from the left edge and 70mm from the bottom, and at the upper right corner, 60mm from the right edge and 65mm from the top. Each mounting unit consists of a 25mm wide vegetable-tanned cowhide strap and a double row of brass D-ring buckles. The strap is secured by double rows of 4mm diameter stainless steel rivets with a rivet spacing of 30mm.

[0034] All connection points of the modular multi-functional grip system 2 are made of standard 304 stainless steel, including: solid rivets with a diameter of 5mm, M5 stainless steel screws, and reinforced washers with a diameter of 13mm. All metal parts are rust-proofed.

[0035] The assembly process of this embodiment is as follows: First, the canvas base layer of the appearance module 3 is pressed and fixed to the shield body 1 with epoxy resin adhesive; after the adhesive layer is completely cured, the preset pattern is printed on the canvas surface using heat transfer technology; then the buffer pad 4 is accurately positioned and pasted; next, the components of the modular multi-functional grip system 2 are installed according to the preset position; finally, overall inspection and functional testing are carried out.

[0036] The modular shield structure provided in this embodiment, through standardized interface design and modular functional partitioning, achieves product customizability, ease of maintenance, and good functional expandability. Simultaneously, this specific implementation provides clear technical feature boundaries for patent protection, facilitating effective intellectual property protection in market competition.
