Description

Technical Field

[0001] The utility model relates to the technical field of training swords, in particular to a segmented teaching and training sword. Background Art

[0002] Existing sponge training swords (also known as safety swords) on the market use a fiberglass rod, nylon rod, or PVC plastic tube as the sword core, with a foamed sponge rubber or foam outer shell. While these swords reduce weight, they are bulky, have high wind resistance, and have a mass distribution significantly different from that of a real steel sword, losing the mass distribution characteristic of a real sword. This results in poor hand feel, and the fiberglass rod (or nylon rod, or plastic tube) bends during collision, losing the usability of a real sword. Furthermore, they offer poor damage reduction from thrusts, resulting in undesirable collisions during clashes, making it impossible to develop the fencing techniques of a real steel sword.

[0003] Patent No. CN201922375558.9 discloses a sword-like safety weapon. The patent's sponge sword achieves damage reduction through a core and sponge coating. The core is constructed from two flat fiberglass strips, creating a hollow core structure. This is intended to reduce damage by bending the blade during a thrust. However, the hollow core significantly weakens the blade section, making it susceptible to lateral deformation and shaking during collision. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a segmented teaching and training sword, which overcomes the shortcomings of the existing sponge sword, is closer in size to a real sword, reduces the impact of wind resistance on the feel, and well simulates the mass distribution and physical properties of a real sword.

[0005] In order to achieve the above objectives, the technical solutions adopted by this utility model are as follows:

[0006] A segmented teaching and training sword, comprising a sword core, the sword core comprising a first sword core layer, a second sword core layer, and a third metal flat bar stacked in sequence and aligned at any ends; wherein the first sword core layer comprises a first metal flat bar and a first glass fiber flat bar connected in sequence from the aligned ends; and the second sword core layer comprises a second metal flat bar and a second glass fiber flat bar connected in sequence from the aligned ends;

[0007] Moreover, the length of the second metal flat bar is less than the length of the first metal flat bar, less than the length of the third metal flat bar, less than the length of the first core layer, and less than the length of the second core layer.

[0008] In some embodiments, the sword core further includes a sword tip disposed away from the alignment end, the sword tip including a straight sword tip end and a thickened end, and the thickened end is connected to the second glass fiber flat strip.

[0009] In some embodiments, a sponge layer is provided on the uncovered portion of the second glass fiber flat strip and on both sides of the sword tip.

[0010] In some embodiments, a sword guard connected to the two thin sides of the sword core is provided at the connection between the second metal flat bar and the second glass fiber flat bar, a buffer device is provided on the outer surface of the sword core on the blade side, and a plastic hilt is provided on the outer surface of the sword core on the hilt side.

[0011] In some embodiments, the buffer device includes a sword core sleeve and buffer air bags respectively arranged on two thin sides of the sword core sleeve.

[0012] In some embodiments, the outer surface of the buffer device is wrapped with sponge rubber and sword body wrapping cloth in sequence from the inside to the outside.

[0013] Beneficial effects of the utility model:

[0014] 1. The training sword of the utility model adopts a combination of composite materials, which overcomes the shortcomings of existing sponge swords. While being closer in size to a real sword, it reduces the impact of wind resistance on the feel of the hand, simulates the mass distribution and physical properties of a real sword very well, and reduces the weight of the front end, which is conducive to cutting and reducing injuries and avoiding unreasonable collisions.

[0015] 2. This new training sword adopts a segmented design, with a buffer space reserved for two-stage stabbing to reduce damage, making it easier for referees and users to observe the stabbing effect. The front end of the sword is wrapped with sponge, which reduces the weight of the training sword and significantly reduces the damage to the human body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described below with reference to the accompanying drawings. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0024] Example 1

[0025] See attached Figure 1 -Attached Figure 5 This embodiment provides a segmented teaching and training sword, including a sword core, wherein the sword core includes a first sword core layer 7, a second sword core layer 8, and a third metal flat bar 3 stacked in sequence and aligned at any end; wherein the first sword core layer 7 includes a first metal flat bar 1 and a first glass fiber flat bar 4 connected in sequence from the aligned ends; and the second sword core layer 8 includes a second metal flat bar 2 and a second glass fiber flat bar 5 connected in sequence from the aligned ends;

[0026] Moreover, the length of the second metal flat bar 2 is less than the length of the first metal flat bar 1 , less than the length of the third metal flat bar 3 , less than the length of the first core layer 7 , and less than the length of the second core layer 8 .

[0027] The utility model divides the entire sword core into five sections through the combination of composite materials and the limitation of material length. Figure 1As shown, from left to right, the sword is divided into the hilt section (approximately the length of the second metal bar 2), the strong blade section (approximately the length of the third metal bar 3 minus the length of the second metal bar 2), the second-strong blade section (approximately the length of the first core layer 7 minus the length of the third metal bar 3), the weak blade section (approximately the length of the second core layer 8 minus the length of the first core layer 7), and the tip. This arrangement concentrates the weight of the entire sword at the rear, helping to reduce damage from slashing blows while maintaining the blade's strength. It also helps the sword's mass distribution resemble that of a real steel sword. Furthermore, the fiberglass strip at the front bends during a thrust, minimizing damage.

[0028] In some preferred embodiments, the dimensions of the first metal flat bar 1, the second metal flat bar 2, and the third metal flat bar 3 are 15mm*3mm*355mm, 15mm*6mm*315mm, and 15mm*3mm*615mm, respectively. The dimensions of the first fiberglass flat bar 4 and the second fiberglass flat bar 5 are 15mm*3mm*560mm and 15mm*6mm*880mm, respectively. When stacked, the bars are stacked with equal widths and secured with rivets.

[0029] In some preferred embodiments, the sword core also includes a sword tip 6 arranged away from the alignment end, and the sword tip 6 includes a sword tip straight end 601 and a thickened end 602. The thickened end 602 is connected to the second glass fiber flat strip 5, and the specific connection method can be socketing.

[0030] The tip 6 can be made of TPU. Its specific structure reduces and cushions the instantaneous force exerted on the body during a thrust. The straight tip 601 requires less force to bend, while the thickened tip 602 and the second fiberglass flat strip 5 require greater force to bend. This two-stage curved design significantly reduces the risk of stabbing damage during training, and the curves allow for a sufficient depth for thrusts. During two-person training, the curved tip also facilitates the judge and user's ability to observe the effectiveness of thrusts.

[0031] In some preferred embodiments, sponge layers 9 are provided on the uncovered portion of the second glass fiber flat strip 5 and on both sides of the sword tip 6. This design adapts to the fact that most sword weapons use the front end to hit the opponent, so the weight of the front end is reduced to reduce the impact force and the sponge layer 9 is added to absorb and cushion the impact, thereby reducing damage to the struck part of the human body.

[0032] Example 2

[0033] See attached Figure 1 -Attached Figure 5This embodiment is based on the embodiment 1 and is a segmented teaching and training sword. The connection between the second metal flat bar 2 and the second glass fiber flat bar 5 is provided with a sword guard 10 respectively connected to the two thin sides of the sword core. The outer surface of the sword core on the sword body side is provided with a buffer device 11, and the outer surface of the sword core on the hilt side is provided with a plastic hilt.

[0034] The thin side of the sword core refers to the side where the length and height of the first metal flat bar 1 are located. Since the sword core is flat, this side is relatively thinner. Figure 3 The sword guard 10 divides the sword core into a sword core on the left side of the hilt and a sword core on the right side of the blade.

[0035] In some preferred embodiments, the buffer device 11 includes a sword core sleeve 12 and buffer air bags 13 respectively arranged on two thin sides of the sword core sleeve 12, and the thin sides of the sword core sleeve 12 correspond to the thin sides of the sword core.

[0036] The buffer device 11 is provided to adapt to the fact that most sword weapons use the rear end of the sword body to collide with the opponent's weapon to achieve the purpose of controlling the opponent's weapon. It has both elastic and rigid characteristics, which makes it convenient for the user to control the opponent's weapon, and wraps the sword core to prevent it from impacting the human body and causing damage.

[0037] In some preferred embodiments, the outer surface of the buffer device 11 is wrapped with sponge rubber 14 and sword body wrapping cloth 15 from the inside to the outside. The sword body wrapping cloth 15 is made of wear-resistant and tear-resistant cloth (polyester or nylon cloth) to protect the sword body buffer layer.

[0038] The mass distribution, hand feeling, volume and collision of the segmented teaching and training sword provided by the utility model are all closer to those of a real steel sword, so that the user can use the skills of a real sword, and the volume is effectively reduced to reduce the influence of wind resistance on the hand feeling.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.
