Description

Roller Sled {Roller Luge}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller sled which travels using rotation of a roller.

Roller sleds are rides equipped with rollers for traveling on flat roads, ramps, tracks and so on. Such a roller sled, when used in a ramp, will travel at a high speed due to gravity, so that a braking device for reducing the speed for the safety of the occupant must be provided.

1 is a schematic bottom view of a roller sled 100 according to the prior art.

Referring to FIG. 1, a roller sled 100 according to the related art includes a first starter 110, a second starter 120, and a braking wire 130.

The first startup portion 110 moves according to the operation of the occupant. The first startup portion 110 receives the operating force of the occupant and moves.

The second startup portion 120 is provided with a roller 121. The rollers 121 provided on the second startup portion 120 move together as the second startup portion 120 moves. Therefore, when the second actuating part 120 moves toward the braking part 140, the roller 121 also moves toward the braking part 140. [ Accordingly, the rotation of the roller 121 is restricted due to friction with the braking unit 140 or the like. The braking unit 140 restricts the rotation of the roller 121.

The braking wire 130 connects the first starting portion 110 and the second starting portion 120 with each other. The braking wire 130 is installed in each of the first starting portion 110 and the second starting portion 120. Accordingly, the second actuating unit 120 moves as the first actuating unit 110 moves through the braking wire 130.

The roller sled 100 according to the related art moves the roller 121 provided on the second startup portion 120 toward the braking portion 140 as the occupant moves the first startup portion 110 . The rotation of the roller 121 moved toward the braking unit 140 is restricted due to friction with the braking unit 140 or the like. Accordingly, the roller sled 100 according to the prior art is decelerated.

Here, the braking wire 130 may be cut due to various causes such as accumulated fatigue and external impact due to repeated braking. However, in the roller sled 100 according to the related art, when the braking wire 130 is cut during running, since the first and second starting portions 110 and 120 are separated from each other, The second starting portion 120 can not be moved through the wire 130. Accordingly, since the roller sled 100 according to the related art can not decelerate in a section requiring deceleration due to cutting of the braking wire 130, there is a problem that the risk of accident for a passenger is greatly increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a roller sled capable of decelerating even if the brake wire is cut.

In the roller sled according to the present invention, one end and the other end of the brake wire are installed at the first starting portion at different positions of the first starting portion, and the restricting portion includes an insertion hole into which the brake wire is inserted , One end of the braking wire and the other end of the braking wire are inserted into the insertion hole so that the first activating portion and the restricting portion are connected by one braking wire, and when the braking wire is cut, And the braking wire is supported by the restricting portion so as to keep the first activating portion and the restricting portion connected to each other.

According to the present invention, the following effects can be achieved.

According to the present invention, even if the brake wire is cut off, the first starting portion and the second starting portion are connected without being separated from each other, so that braking is possible, thereby reducing the risk of accident to the occupant.

2 and 3, the boarding main body 2 is provided with a boarding seat 21. The boarding seat 21 is a seat for an occupant to board. The boarding main body 2 can function as the main body of the roller sled 1 according to the present invention. The first booting section 3, the second booting section 4, and the braking section 5 may be installed in the boarding main body 2.

Referring to FIGS. 3 and 4, the first starting portion 3 is installed in the boarding main body 2. The first activating part 3 may include a first roller 31 for driving the boarding main body 2. The first roller 31 runs on the boarding main body 2 while rotating against the ground.

The first activating part (3) can be movably installed in the boarding main body (2). For example, the first startup portion 3 may be installed in the boarding unit 2 so as to be movable in the first direction (CD arrow direction) and the second direction (DD arrow direction). The first direction (CD arrow direction) is the direction from the second starting portion 4 to the first starting portion 3. The second direction (DD arrow direction) is a direction opposite to the first direction.

The first startup part (3) may be connected to the operation part (10). The operating portion 10 is operated by a passenger. 4, when the passenger operates the operation unit 10, the first activation unit 3 is operated in the first direction (CD arrow direction) and the second direction (DD arrow direction). For example, when the occupant pulls the operating section 10 in the second direction (DD arrow direction), the first starting section 3 can move in the first direction (CD arrow direction). When the occupant pushes the operating portion 10 in the first direction (CD arrow direction), the first starting portion 3 can move in the second direction (DD arrow direction).

3, the second starting portion 4 is installed on the boarding main body 2 at a position spaced apart from the first starting portion 3. In this case, the second startup portion 4 may be disposed at a position spaced apart from the first startup portion 3 in the second direction (DD arrow direction). The second activating part 4 may include a second roller 41 for driving the boarding main body 2. And the second roller 41 runs on the boarding main body 2 while rotating against the ground.

The second activating part (4) can be movably installed in the boarding main body (2). For example, the second activation section 4 may be installed in the boarding unit 2 so as to be movable in the first direction (CD arrow direction) and the second direction (DD arrow direction). Accordingly, the second roller 41 can move in the first direction (CD arrow direction) and the second direction (DD arrow direction).

The second activation section 4 may be connected to the first activation section 3 via the braking wire 7 and the restriction section 6. Accordingly, the second startup portion 4 can move as the first startup portion 3 moves. For example, the second starting portion 4 is moved in the first direction (CD arrow direction) as the first starting portion 3 moves in the first direction (CD arrow direction) and the second direction (DD arrow direction) Direction) and in the second direction (DD arrow direction).

Referring to FIGS. 3 and 5, the braking unit 5 is for restricting the rotation of the second roller 41. The braking unit 5 may restrict the rotation of the second roller 41 due to friction with the second roller 41 or the like. The braking unit 5 may be installed in the boarding unit 2 at a position spaced apart from the second roller 41.

For example, the braking unit 5 may be disposed at a position spaced apart from the second roller 41 in the first direction (CD arrow direction). In this case, when the second roller 41 moves in the first direction (CD arrow direction), the braking unit 5 contacts the second roller 41 to rotate the second roller 41 Can be limited. As another example, the braking unit 5 may be disposed at a position spaced apart from the second roller 41 in the second direction (DD arrow direction). In this case, when the second roller 41 moves in the second direction (DD arrow direction), the braking unit 5 contacts the second roller 41 to rotate the second roller 41 Can be limited.

For convenience, the following description will be made with reference to a case where the braking unit 5 is disposed at a position spaced apart from the second roller 41 in the first direction (CD arrow direction).

The braking unit 5 may be formed of a material such as rubber but is not limited thereto and may be made of any material that can restrict the rotation of the second roller 41 through friction with the second roller 41, As shown in FIG.

5 to 12, the restricting portion 6 is provided in the second activating portion 4. As shown in FIG. The restricting portion 6 may be connected to the first activating portion 4 through the braking wire 7. [ For this purpose, the restricting portion 6 may include an insertion hole 61. The insertion hole (61) inserts the braking wire (7). One end of the braking wire 7 and the other end of the braking wire 7 may be inserted into the insertion hole 61.

The restricting portion 6 may be formed in the shape of a hollow U-shaped tube but is not limited thereto and may be inserted between one end of the braking wire 7 and the other end of the braking wire 7 Or may be formed in other forms.

6, the restriction portion 6 may include a restriction surface 62. [

The restricting surface (62) supports the braking wire (7) inserted in the insertion hole (61). The limiting surface 62 may correspond to a surface disposed in the first direction (CD arrow direction) on the inner surface of the limiting portion 6 formed through the insertion hole 61. The limiting surface 62 can support the braking wire 7 when the braking wire 7 moves in the first direction (CD arrow direction). Accordingly, the restricting portion 6 can move together in the first direction (CD arrow direction) as the braking wire 7 moves in the first direction (CD arrow direction).

The restricting surface 62 may be formed in a curved surface whose center of curvature is located between the restricting portion 6 and the first activating portion 3. The dotted line shown in Fig. 6 shows a comparative example in which the limiting surface 62 is not formed as a curved surface. As shown in FIG. 6, when the limiting surface 62 is formed as a curved surface, the limiting surface 62 supports the braking wire 7 over a wider area than the case where the limiting surface 62 is not formed as a curved surface .

Accordingly, the roller sled 1 according to the present invention can prevent the braking wire 7 from being damaged when the braking wire 7 is supported on the limiting surface 62 as the braking wire 7 moves in the first direction (CD arrow direction) The force per unit length is reduced. Therefore, the roller sled 1 according to the present invention can reduce the possibility that the brake wire 7 is cut, thereby reducing the cycle and cost for maintenance work such as replacement, repair, and the like.

Referring to FIG. 6, the restriction unit 6 may include a restriction hole 63.

The restriction hole (63) allows the braking wire (7) to be inserted. The restriction hole 63 may communicate with the insertion hole 61. The limiting hole 63 may be formed to have a smaller sectional size than the insertion hole 61. Therefore, the restricting hole 63 can further restrict the distance that the inserted braking wire 7 can move, as compared with the insertion hole 61.

Accordingly, the roller sled 1 according to the present invention is implemented such that the degree of shaking of the braking wire 7 is reduced by an external impact such as a vibration generated in a running process. Accordingly, the roller sled 1 according to the present invention not only improves the stability of the braking operation for reducing the speed, but also increases the safety of the passenger, and reduces the possibility of cutting the braking wire 7 , Maintenance and repair work can be further reduced.

6 to 12, the restricting portion 6 may include a support surface 64. As shown in FIG.

The support surface (64) supports the separation preventing portion (8). The support surface (64) can support the separation preventing portion (8) when the brake wire (7) is cut. The process of supporting the separation preventing portion 8 by the supporting surface 64 will be described with reference to the separation preventing portion 8 in the following.

3 to 12, the braking wire 7 connects the first starting portion 3 and the restricting portion 6. [ One end of the brake wire 7 may be installed in the first starting portion 3. The other end of the braking wire 7 may be installed in the first starting portion 3 at a position different from one end of the braking wire 7. For example, the other end of the braking wire 7 may be installed on the first starting portion 3 on the opposite side of the portion where one end of the braking wire 7 is installed with respect to the first roller 31. Between one end of the brake wire 7 and the other end can be inserted into the insertion hole 61. Accordingly, the first starting portion 3 and the second starting portion 4 can be connected to each other via the restricting portion 6 and the braking wire 7.

Hereinafter, the process of decelerating the roller sled 1 according to the present invention will be described in detail with reference to FIGS. 4 and 5. FIG.

First, the occupant can move the first starting portion 3 in the first direction (CD arrow direction) by operating the operating portion 10 during traveling. For example, the occupant can move the first starting portion 3 in the first direction (CD arrow direction) by moving the operating portion 10 in the second direction (DD arrow direction).

Next, the first starting portion 3 can pull the braking wire 7 in the first direction (CD arrow direction) while moving in the first direction (CD arrow direction). Accordingly, the braking wire 7 can move in the first direction (CD arrow direction).

Next, the braking wire 7 is supported on the limiting surface 62 while moving in the first direction (CD arrow direction), thereby pulling the restricting portion 6 in the first direction (CD arrow direction) have. Accordingly, the restricting portion 6 can move in the first direction (CD arrow direction).

Next, the restricting portion 6 can pull the second activating portion 4 in the first direction (CD arrow direction) while moving in the first direction (CD arrow direction). Accordingly, the second startup portion 4 can move in the first direction (CD arrow direction). In this case, the second roller 41 also moves in the first direction (CD arrow direction).

Next, the second roller 41 may contact the bending portion 5 as it moves in the first direction (CD arrow direction). The rotation of the second roller 41 may be restricted due to friction with the bending portion 5 or the like. Accordingly, the roller sled 1 according to the present invention can be decelerated.

3 to 12, the braking wire 7 may include an intermediate wire 71, a first extension wire 72, and a second extension wire 73.

The intermediate wire (71) is inserted into the insertion hole (61). The intermediate wire 71 may be supported on the limiting surface 62. The intermediate wire 71 may be positioned between the first extension wire 72 and the second extension wire 73. One end of the intermediate wire 71 may be coupled to the first extension wire 72. The other end of the intermediate wire 71 may be coupled to the second extension wire 73.

The first extension wire 72 is coupled to one end of the intermediate wire 71. The first extension wire 72 may extend from one end of the intermediate wire 71 to the first activation section 3 and may be installed in the first activation section 3. The first extension wire 72 may be connected to the second extension wire 73 via the intermediate wire 71.

The second extension wire 73 is coupled to the other end of the intermediate wire 71. The second extending wire 73 may extend from the other end of the intermediate wire 71 toward the first starting portion 3 and may be installed in the first starting portion 3. In this case, the second extending wire 73 may be installed in the first starting portion 3 at a position different from the first extending wire 72. The second extension wire 73 may be connected to the first extension wire 72 through the intermediate wire 71.

The intermediate wire 71, the first extension wire 72, and the second extension wire 73 may be integrally formed. That is, the first starting portion 3 and the restricting portion 6 may be connected by one braking wire 7.

Accordingly, the roller sled 1 according to the present invention is superior to the roller sled 1 in that the first extension wire 72 and the second extension wire 73 are not integrally formed but are respectively installed in the first activation section 3 , So that force is uniformly distributed between the first extension wire (72) and the second extension wire (73) during the braking process. Therefore, the roller sled 1 according to the present invention can prevent accumulation of excessive force on any part of the brake wires 7, thereby reducing accumulated fatigue due to repeated braking. Accordingly, the roller sled 1 according to the present invention further reduces the possibility of cutting the brake wire 7, so that the cycle and cost for the maintenance work such as replacing and repairing the brake wire 7 can be further reduced .

7 to 12, the separation preventing portion 8 is provided on the braking wire 7. The separation preventing portion 8 may be installed on the braking wire 7 so as to be positioned between the first activating portion 3 and the restricting portion 6. The separation preventing portion 8 may be supported by the restricting portion 6 when the braking wire 7 is cut. The separation preventing portion 8 can prevent the braking wire 7 inserted into the insertion hole 61 from being detached from the insertion hole 61 by being supported by the restricting portion 6. [

Accordingly, the roller sled 1 according to the present invention is capable of preventing the braking wire 7 and the first starting portion 3 and the second braking wire 7 from being broken through the cut braking wire 7 and the restricting portion 6, And the second startup section 4 are connected to each other. Accordingly, the roller sled 1 according to the present invention can be decelerated even when the braking wire 7 is cut during traveling, thereby reducing the risk of accident to the occupant.

Hereinafter, the process of supporting the separation preventing portion 8 on the restricting portion 6 as the braking wire 7 is cut will be described in detail with reference to FIGS. 7 and 8. FIG.
