Description

A sock absorber of the Inline skates}

The present invention absorbs and alleviates the shock applied to the wheels in a wheeled shoe (aka HEELYS) in which a wheel is coupled to the bottom of a shoe rear axle to enjoy skating play by rolling a rear wheel. The present invention relates to a shock absorber that can provide safety and convenience of operation as well as ensuring safety in use.

The wheeled shoe (also known as heelless), which combines the wheels with the rear wheels of the shoe and rolls the wheels of the rear wheel, allows the skater to play by rolling the wheels of the rear wheel while walking as a shoe.

The wheeled shoes are usually grounded on the ground simply because the wheels of the rear axle does not interfere with walking, and enjoys playing by holding the front of the shoes and performing rolling using the rear wheels.

However, such a wheeled shoe is not equipped with a shock absorber at all, so that external shocks and vibrations (hereinafter referred to as shock) applied to the wheel while the wheel is rolling are transmitted to the human body without being absorbed and alleviated. It causes side effects such as causing pain of the wearer.

In addition, as described above, the problem is that the wearer receives the shock applied to the wheel as it is, and thus the wearer feels deteriorated, and also causes the unnaturalness of the motion during the rolling operation, which causes the inability to provide more active and dynamic skating play. There has been a need for development of cushioning means that can be improved.

Of course, in order to alleviate the impact of the wheels, the material of the wheels is made of elastic shock absorbing material, which is difficult to expect a shock absorbing effect to sufficiently absorb and alleviate the impact on the entire wheel.

The present invention is to provide a shock absorber that can minimize the impact by absorbing and mitigating the shock to the wheel during the activity in the wheeled shoes as a simple structure, various safety problems that can be caused by the impact, etc. In order to solve the problem, and to provide a more stable operation and excellent ignition.

The present invention is characterized in that the shock absorber is configured to absorb and alleviate the shock applied to the wheel of the shoe rear wheel, in a shoe with wheels coupled to the rear wheel of the shoe to enjoy skating play. Looking at the configuration of the invention in detail as follows.

1 is a perspective view showing an embodiment of the present invention, Figure 2, 2a is a cross-sectional view of the present invention, Figure 3 is a cross-sectional view of the working state of the present invention.

The wheeled shoe 1 is composed of a wheel 7 is coupled to the indentation groove 4 of the bracket 3 coupled to the rear axle 2 of the shoe 1, the configuration of such a wheeled shoe (1) Is common.

The present invention is formed between the bracket (3) of the boss (7) and the rear axle (2) of the shoe (1) in which the assembly holes (8,8 ') are formed and the fixed shaft (6,6') of the wheel (5) is fitted. The buffer cylinder 9 is configured to connect the boss 7 and the bracket 3 of the rear axle 2 to which the wheel 5 is coupled as the buffer cylinder 9 to be coupled to each other so that the shock absorbing function is performed.

The buffer cylinder 9 is integrally formed in the boss 7 and the bracket 3 in which the assembling holes 8 and 8 'are formed, to which both fixed shafts 6 and 6' of the wheel 5 are coupled.

That is, the inner cylinder 91 is formed on the bracket 3 to be combined with the outer cylinder 92 formed on the boss 7b to form the cylinder 9, and the shock absorbing member 10 is coupled to the inner side between them. will be.

The inner cylinder 91 formed on the bracket 3 may be configured in plural as shown in the illustrated example, and the shock absorbing member 10 is interposed therebetween so as to be transmitted from the boss 7 to which the wheels 5 are coupled. The shock is absorbed by the buffer member 10 so as to be buffered.

In addition, the bracket 3 is formed with a guide hole 12 in which the locking jaw 12 is formed so that the guide rod 12 of the boss 7 can be lifted and operated, but the end of the guide rod 12 has a locking protrusion ( The guide rod 13 is formed so as not to be separated or separated from the guide hole 12 by forming a 13 to be caught by the locking step 12a of the guide hole 12.

The shock absorbing member 10 coupled to the inner cylinder 91 and the outer cylinder 92 constituting the shock absorbing cylinder 9 and performing elastic operation is implemented by rubber or spring having elasticity and elasticity as shown in the example shown in FIG. The buffer member 10 may be implemented in a variety of materials that can exhibit a buffering force.

4 to 6, 6a shows another embodiment of the present invention,

Several buffer cylinders 9a and 9a which are formed by assembling holes 8 and 8 'to cushion the boss 7a to which the two fixed shafts 6 and 6' of the wheel 5 are coupled by elastic expansion and contraction. ') Is connected to the bracket (3a).

Each buffer cylinder (9a, 9a ') is configured to expand and contract by sliding the inner cylinder (91a) and the outer cylinder (92a), and the elastic member by elastically coupled to the buffer member 10 inside.

The shock absorbing cylinders 9a and 9a 'coupled to the shock absorbing member 10 are coupled to one end on the boss 7a to which the wheels 5 are coupled, and the opposite side is coupled to the bracket 3a. Similarly, the buffer cylinder 9a at the center is coupled to both sides by fixing the bosses 7a and the brackets 3a, and the buffer cylinders 9a 'and 9a' which are obliquely coupled to both sides are inclined to the boss ( The angular movement is coupled to the pin shaft (11) to 7a) and the bracket (3a).

The central buffer cylinder 9a absorbs and alleviates the shock applied to the wheels 5 in the vertical direction, and the shock absorber cylinders 9a 'and 9a' which are inclined at both sides provide the impact applied at various angles such as the lateral direction. By absorbing and mitigating, the impact is evenly absorbed and mitigated from the entire wheel 5.

Both buffer cylinders (9a ', 9a') of the central buffer cylinder (9a) is coupled by fixing both ends with a shaft pin (10), which is to smooth the angular movement during expansion and contraction operation according to the shock absorption It is to provide operability and stable buffering force.

Figure 7 shows another embodiment of the present invention, the assembly hole (8,8 ') is formed, the boss (7b) and the shoe (1) rear axle to which the fixed shaft (6,6') of the wheel 5 is fitted At least one buffer cylinder (9b, 9b ') consisting of a combination of the inner cylinder (91b) and the outer cylinder (92b) between the bracket (3) of (2) is provided, all of them are arranged side by side in the vertical direction Several buffer cylinders 9b and 9b 'are designed to absorb and alleviate the shock applied to the wheels 5 evenly.

In other words, the bosses 7b to which the wheels 5 are coupled and the buffer cylinders 9b and 9b 'connecting the brackets 3b are installed side by side in the vertical direction to prevent the impact applied to the wheels 5 in the vertical direction. The buffer cylinders 9b and 9b 'are evenly dispersed and absorbed to alleviate the buffer effect.

In the above, the shape and number of the buffer cylinders 9 (9a, 9a ') 9b, 9b' may be variously implemented, and the bosses 7, 7a, 7b and the brackets 3, 3a. It goes without saying that the shape of (3b) can also be variously modified.

The present invention configured as described above is to minimize and reduce the impact applied to the wheels 5 smoothly and actively in a relatively simple configuration, thereby improving the rotational operation stability and wearability of the wheels 5, Looking at the operation of the present invention as follows.

The impact applied to the wheels 5 during the running of the wheels 5 is transmitted directly from the wheels 5 to the bosses 7 to which the wheels 5 are coupled, and the shocks transmitted to the bosses 7 are again applied to the bosses (the bosses 5). 7) is finally delivered to the human body, such as the sole and ankle of the igniter through a process that is delivered to the bracket (3) of the combined rear axle (2).

In addition, since the wheel 5 itself, which is in direct friction with the ground, cannot have a shock absorbing means, it is best to absorb and mitigate it so that the shock applied to the wheel 5 is transferred to the wearer to the minimum. Would be desirable.

Thus, the present invention absorbs and mitigates the shock cylinder 9 from the boss 7 which is directly coupled to the wheel 5 and receives the shock applied to the wheel 5, and then brackets mounted on the shoe 1. By transmitting to (3) it is to maximize the buffer effect of the impact applied to the wheel (5).

Unlike the conventional wheel (5) in the present invention is not indirectly coupled to the bottom of the rear axle (2) of the shoe (1), but indirectly through the buffer cylinder (9) connecting the boss (7) and the bracket (3) Since the shock applied to the wheels 5 is not transmitted directly to the bracket 3 coupled to the rear axle 2 of the shoe 1, it is absorbed and alleviated through the buffer cylinder 9 from the boss 7. It is then delivered to the wearer in a minimized state.

That is, the shock applied to the wheel 5 acts on the buffer cylinder 9 coupled to the boss 7 through the boss 7 to which the wheel 5 is coupled, so that the shock absorbing member 10 in the shock absorbing cylinder 9. By pressing the shock absorbing member 10 is elastically stretched, the shock is absorbed, alleviated.

The shock absorbing mitigation effect is achieved by a process in which the impact energy is absorbed and relaxed while elastically operating the shock absorbing member 10 in the shock absorbing cylinder 9 including the inner and outer cylinders 91 and 92.

Therefore, the shock applied to the wheels 5 is absorbed by the shock absorbing cylinder 9 which substantially secures the wheels 5 to the rear axle 2 of the shoes 1, thereby exhibiting excellent shock absorbing ability as well as a feeling of ignition. Improvement and rolling operation of the wheel 5 will be able to ensure more stable.

In the case where the bracket 3a and the boss 7a are connected as several buffer cylinders 9a and 9a 'as shown in FIGS. 4 to 6 and 6a, the inner cylinders of the respective buffer cylinders 9a and 9a' The cushioning member 10 coupled between the 91a) and the outer cylinder 92a is elastically elastically operated against impact and exerts a buffering effect. The central buffer cylinder 9a absorbs and alleviates the impact from the vertical direction. The both shock absorbing cylinders 9a 'and 9a' exhibit fluidity about the pin shaft 11 when the shock occurs, while the inner shock absorbing member 10 elastically expands and contracts to absorb and mitigate shocks from various angles such as the lateral direction. Let's go.

In addition, even in the case where several buffer cylinders 9b and 9b 'formed by coupling the inner cylinder 91b and the outer cylinder 92b are installed vertically side by side, as shown in FIG. 7, several buffer cylinders 9b and 9b' are provided. The shock absorbing member 10 in the inside absorbs and alleviates the shock applied to the wheels 5 to provide a shock absorbing effect as in the above-described example.

As described above, the present invention provides a shock absorber for absorbing and mitigating the impact of the wheels 5 on the wheeled shoes, so that the shock applied to the wheels 5 is transmitted to the human body of the wearer as it is, resulting in abnormalities such as ankles and the like. Many benefits and effects can be expected, such as relieving various safety concerns that can cause a lot of troubles, ensuring a more stable rolling operation (rotational operation) of the wheel 5, and providing a comfortable ignition effect due to shock absorption.
