Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to knee protection pads that are attached to the knee portions of racers' suits in order to protect the racers' knees during motorcycle races.

(Prior Art) Generally, when turning a corner in a motorcycle road race, the racer leans the motorcycle as far inward as possible into the corner because of the need to travel at high speed. For this reason, racers also lean their bodies inward into corners, and when doing so, the knee on the leaning side may come into contact with the road surface.

In addition, to prevent losing balance and falling, a person may intentionally kick the road with his/her knee to maintain balance. To this end, thick adhesive tape was traditionally wrapped around the knees of racers' suits to prevent the suits from wearing out due to friction with the road surface.

(Problem that the invention aims to solve) Just wrapping a thick tape around a suit will not solve the problem.
Friction with the road surface caused both the tape and the suit to wear out in a very short time, putting racers at risk of knee injuries.

(Means for solving the problem) In view of the problem, the purpose of the present invention is to provide pads that effectively protect racers' knees in motorcycle races, and technical means devised to achieve this purpose. It is a knee protection pad that is placed on the front side of the knee part of a motorcycle racer's suit, and is made of a material with excellent abrasion resistance that has a smooth plate-like surface and an outwardly curved pad. The pad is removably attached to the suit by a plurality of fasteners formed in a shape, located in the curved hem portion, and recessed from the surface of the pad.

(Function) When turning a corner in a motorcycle race, in order to run at high speed, the racer 1 tries to tilt the motorcycle 2 along with his body as far inward as possible into the corner, so his knees do not touch the road surface 5 or he maintains his balance. In order to do this, consciously bring your knees into contact with the road surface 5. At this time, suit 3 worn by racer 1
A pad 4 located on the front side of the knee portion contacts the road surface 5 to protect the knee. This pad 4 is formed in an outwardly curved shape, and when the pad 4 comes into contact with the road surface 5, the curved top part tends to contact and wear from there.
0 is located at the curved base of the pad 4, that is, the fixing device 10 is in a position where it is difficult to come into contact with the road surface.In addition, the fixing device 10 is recessed from the surface of the pad 4, so that Even if the pad 4 contacts the road surface, the fixture 10 is prevented from coming into contact with the road surface, and even if the pad 4 is worn, the fixture 10 does not easily come into contact with the road surface 5. In addition, since the pad 4 is made of a material with excellent wear resistance, it does not wear easily due to friction with the road surface, and even if it wears, it can be replaced before the fixture 10 is exposed. . Further, since the pad 4 has a smooth plate-like surface and a curved shape, even if it engages with unevenness of the road surface, no large resistance is generated.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a state in which, when turning a corner in a motorcycle race, a racer 1 tilts the motorcycle 2 along with his body toward the inside of the corner. Knee protection pads 4 are detachably attached to both knee parts of the leather suit 3 of this racer 1. A pad 4 attached to the knee portion of the suit 3 on the inclined side (the left knee side in the drawing) is in contact with the road surface 5.

Pad 4 is made of hard synthetic resin with excellent wear resistance.
For example, it is made of ultra-high molecular weight polyethylene and is formed into a plate shape with a smooth surface and curved in one direction, as shown in FIGS. 2 and 3. Further, the planar projection shape is a square.

The pad 4 is attached to a slightly outer side of the kneecap part of the knee part of the suit 3, which is likely to come into contact with the road surface 5.

To install the pads 4, first place the pads 4 on the front side of the knee part of the suit 3, then place the pads 4 on the back side.
A plate-shaped auxiliary pad 6 made of the same material as the pad 4 is placed at a location corresponding to the pad 4, and then a rectangular sheet 7 made of leather is placed.
is located on the back side of the auxiliary pad 6. As a result, a through hole 8 passing through the pad 4, the suit 3, the auxiliary pad 6, and the sheet 7 arranged in layers is formed in the pad 4.
are located at positions corresponding to the four corners of the A metal claw nut 9 having a cylindrical female screw body 9a, a flange 9b provided at one end of the main body 9a, and a plurality of claws 9c provided around the periphery of the flange 9b is attached to the suit 3, the auxiliary pad 6, and the seat. The claw 9c is inserted into the through hole 8 of the sheet 7 and bites into the sheet 7. The pad 4 is detachably attached to the suit 3 by screwing a metal bolt (fixing tool) 10 into a claw nut 9 through a through hole 8 of the pad 4. Furthermore, in this embodiment, a sponge-like cushion 11 made of an elastic material is bonded to the back side of the sheet 7 with an adhesive for shock absorption. A leather backing sheet 12 covers the suit 3 so as to cover the auxiliary pad 6, the seat 7 and the cushion 11.
It is attached to the back side with adhesive.

As a result, even if the motorcycle racer 1 contacts the knee with the road surface 5 when turning a corner, the contact occurs via the pad 4, so there is no risk of damage to the suit 3 and injury to the knee. Also padded 4
Since it is made of a hard synthetic resin with excellent abrasion resistance, it will not be easily worn out by friction with the road surface 5. Even if the pads 4 wear out due to long-term use, they can be replaced because they are removable from the knee portions of the suit 3. Moreover, since the pad 3 is plate-shaped and has a smooth surface, it does not engage with the unevenness of the road surface 5 and generate large resistance, and therefore does not lose running stability when it comes into contact with the road surface, so it can be driven at high speeds. It is suitable for motorcycle races that require running. Furthermore, since the auxiliary pads 6 are attached to the back side of the knee portions of the suit 3, the knees of the racer 1 can be protected even if the pads 4 are completely worn out during running. In addition, the cushion 11 made of elastic material absorbs shock and greatly protects the knees.

The material of the pad 4 is not limited to hard synthetic resin, but any material with excellent wear resistance may be used.
If metal is used, there is a risk that sparks from friction with the road surface 5 will ignite the oil or gasoline attached to the motorcycle 2 or on the road surface 5, and if the material is made of ceramic, there is a risk that it will break and fragments will stick to the racer. Therefore, a material such as a hard synthetic resin having a certain degree of toughness is preferable. Therefore, in this embodiment, since the bolt 10 for attaching the pad 4 is made of metal, the through hole 8 of the pad 4 is made a deep hole as shown in FIG. to prevent contact with the road surface 5.

In addition, the reason why the pad 4 is curved in one direction is to fit it to the knee, and the reason why the planar projection shape is square is that when one side becomes uneven and wears out, the direction of attachment to the suit 3 can be reversed. This is for the purpose of Note that the curved shape may be such that the surface of the pad 4 is a part of a spherical surface as shown in FIG. Further, as shown in FIG. 5, one corner 4' of the pad 4 may be made to have an overhanging shape so that when attached to the suit 3, the corner 4' protects the kneecap.

FIG. 6 shows a case in which the pad 4 is attached to the knee portion of the suit 3 in the same manner as in the above embodiment except that attachment holes 13 are opened along the inside circumferential edge of the pad 4.
This makes it convenient to replace the auxiliary pads 6 and the like without turning the suit 3 inside out.

(Effects of the invention) The knee protection pad 4 for a motorcycle racer according to the invention is made of a material with excellent wear resistance and is formed into a plate shape with a smooth surface and an outwardly curved shape. Since it is removably attached to the suit with a plurality of fixing devices located in the pad surface and recessed from the pad surface, when the racer 1 turns a corner, if the knee comes into contact with the road surface 5, or if the knee If you intentionally make contact with the road surface 5, the pad 4
There is no danger of damaging the suit 3 and injuring the knee, as contact will occur through the pads 4.
The fixture 10 for attaching is located at the curved base portion, that is, at a position where it is difficult to contact the road surface 5, and
Since it is recessed and does not come into contact with the road surface 5, even if the pad 4 wears out, the fixture 10 will not easily come into contact with the road surface 5, and the fixture 10 may be damaged and the pad 4
It won't come off or become impossible to attach or detach. Further, the pad 4 does not easily wear out due to friction with the road surface 5, and even if it wears out due to long-term use, it can be replaced. Moreover, since the pad 4 has a smooth plate-like surface and a curved shape, it does not engage with the unevenness of the road surface 5 and generate large resistance, making it suitable for motorcycle races that require high-speed running. .
