Improved structure of Inline Skates

FIELD TO WHICH THE INVENTION RELATES

The present invention relates in particular to inline skates and in particular to inline skates with the combination of a 'one-way roll' stopper and a buffer, with which the inline skates have a superior braking effect when sliding, and with which they also have better be able to maintain a strong acceleration. Due to the improved structure of the inline skates, they are more ergonomic, there is less chance of sport injury and they offer more comfort.

BACKGROUND OF THE INVENTION

Inline skating is growing as a sport. To date, different types of skates have been developed, mainly for recreation, cross-country, acrobatics and art and speed riding. The skates for cross-country and speed riding have special frames that meet the specific requirements for speed or for the special environment in which they are used. It is also important that they can be used for special and long-term training. The basic structure and operation is the same as the recreation inline skates, the special characteristics of the inline skates of these types are not described here. In the next section the inline skates are described for recreation, acrobatics and figure skating.

Firstly the inline skate for recreation. This consists of a shoe placed on the base, including a number of wheels. There is no brake pad on the front. Upon sliding the left leg, force is applied with the right leg by pushing it backwards, slightly different from the direction in which the left leg slides. Because of the larger wheel diameter, it is more tiring to tilt the legs in turn in order to be able to drive for a long time. It is also not a natural movement for the body. In addition, inline skates do not offer sufficient braking power for recreation. Some brands attach brake pads behind the skates. During braking, the athlete must lift his forefoot while pushing down his heel. This causes the brake pads to slide over the floor under the ankles. This causes a slight braking effect. However, it does not give a good result, and the inhibitory action is unnatural to the body. Another side effect of the rear brake pads is that the legs stay close to each other and sometimes touch each other, so that the athlete can stumble if he wants to alternate with his legs or when making turns (forward or backward 5-stroke strokes). In practice, most athletes remove the rear brake pads, which means that they actually only exist in name.

For figure skating, a brake pad is placed at the front wheel of a recreational inline skate and all wheels are smaller and are located exactly behind the front brake pad. That is why riding with an artificial skate is slower and unstable. 10 At the end, the center of gravity leans forward. In case of inattention, the brake pad on the spreading foot can hit the ground very easily, which is very dangerous, as it can cause the athlete to fall over.

No brake is attached to an inline skate for acrobatics, because a brake like that on a recreation or an artificial skate gets in the way of acrobatics movements and is therefore dangerous for the athlete. However, that does not mean that inline skate acrobatics does not need a brake, because it often happens that athletes fall when they do acrobatics. There has even been serious injury.

In short, the various inline skates do not have an effective and safe braking system. A special way of braking is the T-stop. Hereby a quick turn of a quarter of a turn is made so that the skates are perpendicular to the direction of travel, which means braking. However, this movement requires a lot of practice. The least distraction usually causes a fall, with injuries such as grazes, injuries due to a collision and sprains. In addition, it is not a natural movement for the body. Furthermore, it causes great wear to the skates and the T-stop cannot be applied to every terrain. If the surface is smooth, uneven, or gives too much grip, the T-stop usually ends in a fall. That is why a better brake is needed for inline skates, so that these problems and thus the incurrence of regular injury can be solved

Because of the disadvantages and shortcomings of in-line skates, as described above, the present invention provides in-line skates that are ergonomic, prevent injury, absorb shocks and, moreover, are comfortable. Furthermore, the inline skates of the present invention have multiple brakes and it is possible to accelerate more powerfully. Because they also offer more support when the body is upright, these inline skates are safer for athletes.

5 SUMMARY

One of the objectives of the present invention is to provide an improved structure of inline skates, whereby a better braking system is created while the skate is also ergonomically better. Furthermore, the inline skates according to the present invention offer more support when the body is upright, thereby preventing tumbling. Therefore, the risk of injury is significantly less and the skating becomes much safer.

Another object of the present invention is to provide the inline skates with an improved structure with which more speed can be accelerated and which is more comfortable because shocks are better absorbed. This thus improves the quality of the inline skates.

In order to meet the objectives and effects described above, the present invention provides an improved structure of inline skates, including a shoe, a base, a wheel set, one or more one-way roll stoppers and one or more pads . If there is pressure on the base, there will be a pressure of 20 on the wheels. The pad relieves pressure by being compressed. One or more 'one-way roll' stoppers stop rolling by compressing the pad. This slows down and stops the acceleration. An additional advantage is that the pad also absorbs shocks.

To clarify the structure and properties as well as the efficacy of the present invention, detailed description of the present invention follows, with preferred embodiment and associated numbers.

DETAILED DESCRIPTION

Figures 1 to 3 show an improved structure of inline skates according to a first preferred embodiment of the present invention. The inline skate 100 comes with a shoe 10, a base 20, a wheel set 30, a 'one-way roll' stopper 40 and 20 a cushion 50.

The base 20 is adapted to the bottom of shoe 10 and consists of one or more connecting plates 21 and two side plates 22 which fit under both sides of connecting plate 21. At the front of side plates 22, an elongated pivot hole 221 is provided. Behind and above the elongated turning hole 221, there are holes 25 222 for mounting. Furthermore, behind the elongated turning hole 221, there are three other turning holes (not shown in the figures) that allow the wheels 30 to turn. The wheel set 30 consists of a front wheel 31, two central wheels 32 and a rear wheel 33. The front wheel 31 is placed between the two aforementioned elongated pivot holes 221, by means of a nut bolt mounting 34. The central wheels 30 and the rear wheel 33 are inserted between the corresponding pivot holes placed in side plates 22 behind the elongated pivot holes 221, by means of a nut bolt mounting 35.

The 'one-way roll' stop mechanism 40 comprises a gear 41 and an anchor 42. The gear 41 is circular and has a slightly smaller diameter than the front wheel 31. It is integrally manufactured and is centrally mounted on both sides of the front wheel 31. The annular plates can be fixed in the middle of both front wheels 31. First, the teeth 411, hook-shaped in one direction, are attached to the periphery of the gear 41. The anchoring 42 has a flexible plate 421 and anchors 422 mounted on both sides below the flexible plate 421. The flexible plate 421 is somewhat U-shaped . According to a preferred embodiment, the form is used here as a description, but in no way limits the operation. At both ends of the flexible plate 421, there are two wing plates 423, which are bent upwards and outwards. One or more sets of a plurality of second teeth 425 are mounted on anchor 422, which has two elongated holes 424. The anchoring 42 is secured in mounting holes 222, by means of nut bolt mounts 426 through the elongated holes 424 and mounting holes 222, and the wing plates 423 of the flexible plate 421 are fixed to the underside of the parallel connecting plate 21, while the second teeth 425 of the anchors 422 are flush with the first teeth 411 of the gear wheels 41. As a result, the anchoring 42 can slide up and down in the elongated holes 424, by means of the nut bolt mounting 426. Moreover, because the flexible plate 421 is flexible and can expand and contract, For example, the anchoring 42 may have the effect of a cushion, which happens when the gear 41 is stuck but can slide freely.

The fender 50 is mounted on one side of the side plates 22 and has two sliding block and box mounts 51, two springs 52, two adjustment shafts 53 and two nuts. The sliding block and sleeve mounting 51 consists of a mounting with a sleeve 511 and a sliding block 512, an elongated block that connects to the elongated turning hole 221 which is shorter. There is a 514 pivot hole at the bottom of the sliding block and sleeve mounting. The pivot hole 514 is used to attach nut bolt 34 and to secure the sliding block and sleeve 51 against the front wheel 31 with the insert of sliding block 512 in the elongated hole 221. A groove 513 is adapted to the top of the sleeve 511 (as shown in Figure 3) for spring 52 and 6 adjustment shaft 53. Spring 52 surrounds adjustment shaft 53, the top of which is attached to connecting plate 21. Furthermore, thread is provided on adjustment shaft 53 on which two nuts 54 are screwed that spring 52 between groove 513 and nuts 54. By adjusting the thread locations of nuts 54, the buffering action of spring 52 can be adjusted. In this way, the requirements of athletes can be met at any time, such as with different weights and different requirements for buffers.

See figure 3. The first teeth 411 on gear 41 of the 'one-way roll' stopper 40 point in the opposite direction of the second teeth 425 to the anchor 422 of the anchor 42. When the gear 41 makes contact with the anchor 42 , in the direction of rotation of the gear 41, there can be two consequences: blocking and stopping, and a free sliding and rolling. If the one-way roll stopper 40 is mounted on the front wheel 31, it is installed to allow the gear 41 and the anchor 42 to roll forward in the free-shift and roll-through status and in the block and stop status about the gear 41 roll back. Therefore, if the 'one-way roll' stopper 40 is arranged in the front wheel 31, it can stop the front wheel 31 when the front wheel 31 rolls back.

See Figure 4. Generally, when the inline skates roll forward, the weight of the athlete is evenly distributed across the front wheels 31, the two central wheels 32 and the rear wheel 33. In this scenario, the front wheel 31 operates normally and the gear 41 does not come into contact with anchoring 42. Even if the athlete exerts pressure on the front wheel 31, the front wheel 31 will not stop rolling. This is because when the inline skate moves forward, the front wheel 31 and therefore the gear 41 also roll forward. As a result, the gear 41 and the anchoring 42 are not blocked. Due to the flexible buffering action of the anchor 42, the gear 41 and anchor 42 are in the free-shift and roll-over state.

See figure 5. The braking effect of the 'one-way roll' stopper 40 applied in the front wheel 31 is equal to the teeth on a normal figure skate or to the brake pad on a conventional roller skate and is applied by pushing the toes downwards. when reversing. If acceleration is desired, the 7 reverse propulsion leg uses the front wheel 31 to propel in reverse. At that time, the front wheel 31 rolls backwards. When the athlete has to brake or accelerate, the front wheel 31 is pushed down. Then the front wheel 31 rolls backwards. Due to the downward pressure on the fender 50 due to weight, the gear wheels 41 on the sides of the front wheel 31 block by the anchoring 42 and are stopped. In this way the rolling of the front wheel 31 is stopped in one direction. This also provides for a braking effect or the retention of forward acceleration. The result is that when the front wheel 31 is rolling forward, the gear 41 and the anchoring 42 are in the free-shift and roll-over status under downward pressure. On the other hand, when the front wheel 31 rolls backwards, with downward pressure the gear 41 and the anchoring 42 will be in the closing and stopping status.

Figure 6 shows a schematic diagram of an improved structure of inline skates according to a second preferred embodiment of the present invention and is used to describe the fact that a "one-way roll" stopper 40 "and a fender 50" are mounted on the rear wheel 33. The difference between the current embodiment and the previous embodiment is that the 'one-way roll' stopper 40 'is provided to stop rolling when rolling forward. That is, the direction of the first teeth 41Γ of a gear 41 'and of the second teeth 425' of an anchor 42 'are opposite to the directions of those mounted on the front wheel 31. That means that when an athlete has to brake or when he almost falls backwards, he can exert pressure on the rear wheel 33, due to his weight, that the gearwheel 41 'on the side of the rear wheel 33 fixes the anchoring 42' and in this way hinders that it rear wheel 33 rolls in one direction. Braking power is obtained in the same way and the athlete is prevented from falling back. In addition, the braking effect according to the present preferred embodiment is superior to the braking effect of the rear brake pad in a recreational inline skate with the previous action, without the disadvantages and the danger that the latter entails.

Figure 7 shows a schematic diagram of an improved structure of 30 inline skates according to a third preferred embodiment of the present invention. The third preferred embodiment is based on the first preferred embodiment, described above 8. The gear 41 and the anchoring 42 are arranged identically. The difference is in the design of the fender 50. The side plates 22 of the base 20 further have front side plates 23 on both sides. The end of the face plates 23 is connected to the side plates 22, and the front side thereof is used for turning the wheel 31. Furthermore, a groove 515 is provided in the sleeve 511 of the cushion 50. In that groove 515, a ring-stop face 516, which is used to stop spring 52. As the adjustment shaft 53 passes through groove 515, a nut 517 is used to secure it. As a result, the position of the front wheel 31 can be fixed by means of front side plate 23, sleeve 511, and the adjustment shaft 53. Furthermore, the force of compression of the spring 52 can be adjusted by adjusting the nuts 54. The fender 50 is also connected to the connecting plate 21 as a turning mechanism 55. The front wheel 31 can thereby break shocks even better.

Figure 8 shows a schematic diagram of an improved structure of inline skates according to a fourth preferred embodiment of the present invention. The fourth preferred embodiment of the present invention is based on the third preferred embodiment of the present invention described above. The fourth preferred embodiment of the present invention uses various means for performing one or more one-way roll stoppers 40A. The adjusting shaft 53 of the fender 50 is mounted on a pivot hole 24 for side plate 22. The other end of the fender 50 is fixed to the front wheel 31 and the front side plates 23 with a nut bolt 34. However, for carrying out the aforementioned one-way roll 'stopper 40A, another means is applied. First, a plurality of arcuate holes 230 are provided in the front face plate 23, 25 and a pivot hole 231 in the center of these arcuate holes 230. In addition, the "one-way roll" stopper 40A includes a side gear 401, as well as an anchor 402. The side gear 401 is mounted in the front wheel 31. The side anchor 402 has an annular body 402A, one side thereof has one or more teeth 402B. These teeth 402B correspond to the side gear 401 and can block each other or slide freely. As the front wheel 31 rolls forward, said teeth 402B slide freely relative to gear 401. On the other hand, if the (9 front wheels 31 roll backwards, said teeth 402B will lock with the side gear 401. On the other side of the annular body 402A, a plurality of first pin members 402D and a plurality of second pin members 402E, both annularly distributed, the first pin members 402D are thicker than the second pin members 402E and a groove 402C is provided at the end of each second pin members 402E The plurality of surrounding arcuate holes 230 are larger than the plurality of first members 402D and second pin members mounted on one side of the annular body 402A of the side anchor 402. Further, the side anchor 402 passes through the plurality of surrounding arcuate holes 10 230 arranged in the front side plate 23, whereafter a second compression spring 407, an intermediate piece 406, the first compression spring 405, a specially shaped spacer 404 and a hook ring 403 are provided The hook ring 403 can be clamped onto a groove 402C. The inner radius of the spacer 406 is smaller than the outer radius of the circle surrounded by the first pin members 402D and the flexible force 15 of the second compression spring 407 is smaller than that of the first compression spring 405. Therefore, an actuator 408 is provided second compression spring 407, spacer 406, first compression spring 405, specially shaped spacer 404 and hook ring 403. Due to the function of the first compression spring 405 and the second compression spring 407, the annular body 402A of the side anchor 402 is close to the front side plate 23, under 20 normal conditions. Furthermore, the drive 408 is mounted on side plate 22 and above specially shaped intermediate piece 404. When weight presses on connecting plate 21, the fender 50 is compressed, which closes the drive 408 and contact with specially shaped intermediate piece 404 occurs. Because the contact surface of the drive 408 on the specially-shaped intermediate piece 404 is an inclined surface 408A, when drive 408 is depressed, this will create a pressure on the specially-shaped intermediate piece 404 near the front face plate 23. Nevertheless because the inner radius of the spacer 406 is smaller than the outer radius of the circle surrounded by first pin members 402D, and the flexible force of the second compression spring 407 is smaller than that of the first compression spring 405, the compression force will do not compress the first compression spring 405 on the front of the front side plate 23, but will cause the intermediate piece 406 to be the second The compression spring 407 compresses, causing the side anchor 402 to move to the side gear 401. At this time, as the front wheel 31 rolls backwards, the side gear 401 blocks the side anchor 402 and stops rolling in one direction. On the other hand, if the front wheel 31 is rolling forward at that time, due to the depression of the first compression spring 405, the side gear 401 and the side anchor 402 will move freely.

From the foregoing it appears that the present has at least the following effects and provisions: 1. If the fender and the one-way roll stopper according to the present invention are arranged on the front wheel, the front wheel, when pressed down slightly at the backward rolling, the backward rolling stop in one direction. When the fender and the one-way roll stopper of the present invention are mounted on the rear wheel, the rear wheel, when slightly depressed during forward rolling, can stop forward rolling in one direction.

2. According to the present invention, the backward rolling is stopped in one direction if the forward propulsion is obtained by pressing backwards, because the forward leg is pressed down by the weight and the front wheel is pushed backwards, whereby it is pushed backwards. following rolling position. This results in a more powerful, ergonomic propulsion.

3. The action of the brake on the front wheel according to the present invention is equal to the teeth on the front of a normal figure skate or the brake pad on the front of a roller skate and works by pushing the toes downwards when sliding backwards . At that moment there is pressure on the front wheel when rolling backwards, creating a braking effect that is more ergonomic and safer. The braking effect of the rear wheel is the same as that of the rear brake pad in a recreational inline skate. When the athlete slides forward and uses force to lift his feet while his weight is pressing on the rear wheel, the rear wheel will be slightly pressed at that moment and an inhibiting effect will follow that stops the forward movement. The braking effect is superior to the braking effect of the brake pad at the back of a recreational inline skate without the disadvantages and danger of the latter.

4. Because of the provisions in the front and rear wheels of the present invention, the shocks are absorbed as the athlete advances, by the pads provided therein, therefore there is less stress for the ankles and toes. This makes the skates ergonomic.

5. When the athlete almost falls over, because there is pressure on the front wheel when reversing, a braking force is created that stops reversing and in one direction. As a result, the athlete automatically receives support when the body is upright. When the athlete almost falls backwards, because there is pressure on the rear wheel due to the weight when rolling forward, a braking force is created to stop the forward movement. In addition, the athlete receives automatic support when the body is upright. The said description is only a preferred embodiment of the present invention, and is not intended to limit the content and scope of the present invention.
