Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rudder sled.

[0002]

2. Description of the Related Art Conventionally, a sled such as a general snow boat used as a playground equipment for sliding down a slope covered with snow is a simple sled having a bottom surface of a seat plate or a basket on which a user rides as a sliding surface. Was something.

[0003] Such steering of the sled is performed by tilting the sled in a required direction while the user balances his or her body. Because of this, you can only change direction slowly,
It was inconvenient to use, and when used as a playground equipment, the skiing was monotonous and was of little interest.

[0004] As a sled which solves these problems and can be easily steered, and which can be slid variously even when used as a playground equipment, it is a utility model registration No. 252257 according to the inventor's invention. 2. Description of the Related Art A rudder sled shown in this document is known (hereinafter, such a rudder sled is referred to as conventional).

[0005] In the conventional sled with a rudder, a seat portion on which the buttocks of a user separated from each other are placed and a steering portion placed in front of the seat portion are connected by a string-like connecting member.
It is possible to change the course in the left-right direction by a steering operation, that is, to adjust the balance between the forces of the right and left feet applied to the steering section. In addition, even when used as a playground equipment, the user can enjoy a variety of slides with the user's will to some extent.

[0006]

However, in the rudder sled, the reins have their leading ends connected to the front end of the sheet portion or the rear end of the string-like connecting member, so that the posture of the user is stabilized. It does not even contribute to steering. Therefore, it is necessary to perform the steering operation with the addition of the force of both feet, and there is a problem that a delicate and stable steering operation is difficult.

The rudder sled does not have a braking portion. In order to brake or stop the sled, both legs are pressed against a snow surface, or the rear edge of the bottom surface of the rudder is moved by both legs. Even if the steering portion is tilted so as to hit the snow surface, there is a problem that the effect of braking or stopping the sled is insufficient, and it is difficult to perform this.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a seat portion having a seating surface on which a user's buttocks are placed on an upper surface and a plurality of sliding guide protrusions extending in a front-rear direction on a lower surface is provided. The upper part has a contact portion for contacting the sole of the leg of the user who has come forward in the sitting posture, and has a plurality of sliding guide protrusions extending in the front-rear direction on the lower surface to further brake the sled. A steering section having a blade for connecting the seat section and the steering section, and a bridle having one end attached to the left and right sides of the steering section and the other end extending to the user's hand. This is achieved by a rudder sled.

It is preferable that the slide guide ridge on the lower surface of the seat portion is curved inward. With this configuration, clockwise and counterclockwise rotation of the seat portion is performed more effectively.

[0010] It is preferable that the reins extend in a U-shaped loop from a predetermined portion of the steering portion to a user's hand. The reason will be described later.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a rudder sled 1 according to an embodiment of the present invention. 2 is a right side view of the rudder sled 1 of FIG. 1, FIG. 3 is a bottom view of the rudder sled of FIG. 1, FIG. 4 is a front view of the rudder sled of FIG. 1, and FIG. FIG. 3 shows a rear view of a rudder sled. As shown in FIG. 1, the sled includes a sheet portion 2, a steering portion 3, a string-shaped connecting member 4, and a bridle 5.

The seat portion 2 has on its upper surface a seating surface 21 on which a user's buttocks are placed, and has a plurality of sliding guide ridges 22 extending in the front-rear direction on its lower surface as shown in FIGS. doing. As shown in FIG. 3, it is preferable that the plurality of slide guide ridges 22 be curved inward. In some cases, the ridge 22 may be straight. For smooth sliding, it is desirable that the sliding guide ridge 22 has a curved portion 23 at the tip end as shown in FIG. A plurality of grips 25 are provided on the upper surface of the periphery of the sheet portion 2 for gripping the user in order to stabilize the posture when sliding on a monotonous snow surface with little undulation, or gripping when carrying the sled. ing.

The steering section 3 has on its upper side an abutment section 31 for abutting the sole of the leg of the user who has come forward in a sitting posture, and includes a plurality of sliding guide projections 32 extending in the front-rear direction. It has it on the lower surface. The contact portion 31 has an inclined surface so that the sole can be contacted in a natural posture. Further, as described above, it is desirable that the sliding guide ridge 32 has a curved portion 33 whose front end portion is curved upward. Further, the steering portion 3 is provided with a blade 34 for braking or stopping the sled, and pulls down the reins 5 while stepping on the heel contacting the contact portion 31 to lower the rear side of the steering portion 3. When a directional force is applied, the blade 34 cuts into the snow surface and functions as a strong stopper. Blade 34 in steering section 3
As a preferred example, the lower part of the rear surface of the steering section 3 can be cited as a preferred example.

The seat 2 and the steering 3 are preferably made of plastic, wood or the like. The slide guide ridges 22 and 32 are formed of plastic, bamboo, wood, or the like. In the case of plastic, the sheet portion 2 and the steering portion 3 can be integrally formed.

The string-like connecting member 4 is not limited to a belt-like string as in this example, but may be a rope, a chain, or the like, and connects the sheet portion 2 and the steering portion 3. The string-shaped connecting member 4 can be adjusted to a length that fits the body of the user, and can be used for children and for large use if the distance between the sheet portion 2 and the steering portion 3 is adjusted. . In addition, since the connecting member is a flexible string-like member, a leg or hand is tightened between the steering member and the connecting member, which is likely to occur when a rod-shaped rigid member is used as the connecting member. Excellent safety with no danger of pinching. Further, the steering portion is not lifted even on a rugged running surface, and the steering operation can be performed reliably.

The reins 5 have one end attached to the left and right sides of the steering section 3 and the other end extending to the user's hand. Unlike the conventional reins 5, the reins 5 not only stabilize the posture by the user gripping, but also contribute to the operation of the steering section 3. That is, the direction of the steering unit 3 can be adjusted by pulling the left hand side of the reins 5 gripped by both hands, and in this case, the left foot placed on the contact unit 31 can be sufficiently depressed in a stable posture, thereby The right course of the sled can be successfully changed. By pulling the right hand side of the reins 5, the direction of the steering section 3 can be adjusted, and in this case, the right foot placed on the contact section 31 can be sufficiently stepped on in a stable posture, thereby changing the leftward course of the sled. Can be performed successfully. By attaching the reins according to the present invention to the steering portion in this way, a better steering operation can be performed as compared with the conventional case where the steering operation is performed with the force of both feet. Further, by adjusting the tension of the bridle and the tension of the foot, a delicate steering operation can be performed. Further, as described above, if the heel is stepped on while pulling the reins 5 with both hands to apply a downward force to the rear side of the steering section 3, the blade 34 functions as a stopper.

Preferably, the reins 5 extend in a U-shaped loop from a predetermined portion of the steering portion 3 to the user's hand in that the reins 5 are easy to grasp and easy to perform a steering operation. In addition, the bridle 5 of this shape facilitates the carrying of the sled 1 when used as a towline as described later.

In this embodiment, the seating surface 21 of the seat 2 is
The width and the length of the sled 1 are made larger than the width and the length of the steering part 3, respectively. The sled 1 is carried without being bulky by placing the steering part 3 on the seat surface 21 of the sheet part 2 during transportation. It will be easy. Also, the reins 5 can be used as a tow line when the sled 1 is carried.

Next, a method of using the sled 1 will be described.

The user places the sled 1 on a slope covered with snow or the like, places the buttocks on the seating surface 21 of the seat portion 2 and sits down, and puts out the legs forward to abut the steering portion 3. It is placed on the part 31 with the sole in contact. The length of the string-like connecting member 4 is adjusted so that the sole presses the contact portion 31 with an appropriate force. When the foot on the snowy slope is put on the contact portion 31 as described above so that the sled 1 does not slip, and the foot is separated from the snowy surface, the sled 1 starts to slide on the slope. During the run, the user can control the traveling direction of the sled 1 in the manner described above. Further, in order to brake or stop the sled 1, this can be performed in the manner described above.

The sled according to the present invention can be used not only on a snow surface but also on a lawn, grass surface, sand surface or the like having a moderate inclination.

[0022]

The rudder sled of the present invention has a structure in which one end is attached to both left and right sides of the steering portion and the other end is provided with a bridle extending to the user's hand. In contrast to performing the steering operation by adding and subtracting the force of both feet to the steering wheel, a delicate and stable steering operation can be performed by operating the reins and adding and removing the force of both feet to the steering section.

Furthermore, since the rudder sled of the present invention has a configuration in which the steering portion is provided with a blade, if the reins are pulled with both hands and strong force is applied to both feet placed on the steering portion, the blade can be removed from the snow. The sled can be reliably braked or stopped by penetrating into the slope, and the required braking can be controlled at will by the user by adjusting the tension of the reins and the tension of both feet. It is.
