CONSTITUTION:A roller 2 is composed of four roller elements 31-34. For each roller element 3, its parts corresponding to the center part and both edge parts of the roller 2 are made thicker, parts corresponding to the respective middle parts between the center part and both the edge parts of the roller 2 are made thinner, a sliding surface is made into a gentle round shape along the center line of the sliding down passage, further, both sides of the sliding surface are made into a gentle valley shape, the length of the roller element 3 is 80-120mm, the diameter of a thick passage edge (a) of the element 3 is 35-50mm, the diameter of a thin passage edge (b) is approximately 30-45mm, and the element 3 gradually becomes thinner from the thick passage edge (a) to the thin passage edge (b). The sliding surface is made into a bent surface to match with the shape of the hip when a person sits on this sliding surface, and when the person sits on the center of this sliding surface, the hip is placed on a round part, and thighs are to be positioned on right and left valleys. Thus, even when the person slids down the sliding surface, the person never feels a pain in the hip.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a free-rotating roller constituting the sliding surface of a roller slide, and is particularly characterized in that it is formed by four roller elements.

<Prior Art> In recent years, roller slides have been used in many slides.

This roller slide has a large number of free-rotating rollers arranged in parallel between left and right side plates, which serve as a sliding surface.

Therefore, on this slide, there is almost no sliding movement between the person sliding down the slide and the roller surface, so the appearance of the sliding surface is better than that of a conventional slide where the sliding surface is made of board material. Sliding friction is significantly reduced, and there is almost no risk of frictional heat being generated due to sliding friction with the sliding surface or wear of clothing when sliding downhill.

The lick roller slide makes it possible to create a long slide, and by changing the inclination angle along the way, it is possible to add variety and thrill to the downhill slide, so unlike traditional slides, it is simply a slide for young children. It is expected that it will not only be used as play equipment, but also widely used for leisure and sports.

(Problems with the prior art) As mentioned above, roller slides have lower apparent sliding friction on the sliding surface compared to conventional slides in which the sliding surface was constructed using plate materials, causing frictional heat to be generated and clothing to be damaged. Because there is less wear and tear, it is now possible to create long downhill trails. However, like the previous skating white, the downhill course on the downhill surface is not constant, so if you lengthen the downhill trail, you will gradually move from side to side while descending. This may cause problems such as being deflected, contacting the side plate, and sliding against it.

In addition, since the sliding surface of roller slides is made up of rollers, it is a kind of uneven surface, so if the slide length is long and the speed of the slide is increased, the buttocks of the people sliding down the slide may become painful9. Therefore, the appearance of the sliding surface of the conventional roller sliding white is 11! Even though the friction resistance is low, the downhill path can be made longer,
It was not possible to speed up the descent.

(Objective) It is an object of the present invention to provide a roller slide that allows the user to slide down the slide along the center line of the slide and that does not cause pain to the buttocks during the slide.

(Structure of the Invention) The roller according to the present invention is formed by four roller elements.

Each roller element has a length of 80-120, the wide end is 35-50, and the narrow end is 30-451.
It gradually becomes thinner from the wide meridian end to the thin meridian end, and the rate of change in diameter is extremely small near the wide meridian end; In the part near the meridian end, it becomes gradually smaller again,
Among the four roller elements, the two roller elements on both sides have their wide longitudinal ends located on the outside, and the two inner roller elements have their wide longitudinal ends located in the center.

(Function) The sliding surface of the roller slide should be set so that the wide end is 35 to 5.
0m5. By using rollers consisting of four roller elements with narrow ends of about 30 to 45 mm, a gentle mountain shape is formed on the sliding surface along the center line of the downhill track, and furthermore, a gentle mountain shape is formed on both sides of the roller. A valley is formed.

(Example) Hereinafter, the roller for a roller slide according to the present invention will be specifically described based on the illustrated example.

Figure 1 shows a longitudinal cross-sectional view of the slideway of the roller slide.
The basic structure of the slide is the same as that of a conventional roller slide.

That is, the slideway is formed by a pair of left and right side plates 1.1 provided at an interval of about 350 to 500 mm and a large number of freely rotating rollers 2.
Support shafts 4 are horizontally installed at regular intervals between them, and rollers 2 are attached to these to form a sliding surface.

This roller 2 has four roller elements 3□~34
It consists of

The roller element 3 is made by making the center and both ends of the roller 2 thicker, and making the middle part thinner, so that the sliding surface is shaped into a graceful mountain shape along the center line of the downhill track, and further shaped into a gentle valley shape on both sides. The length is 80-120m5. The diameter is about 35 to 50 m+s at the wide end a and 30 to 45 m+s at the thin end, and gradually tapers from the wide end a to the rope end.

FIG. 3 shows an enlarged view of the change in the diameter of the roller element 3. The rate of change is extremely small near the wide end a, and gradually increases toward the narrow end.
It becomes gradually smaller again near the end of the narrow meridian.
There is almost no change in the areas near both ends.

It should be noted that among the four roller elements, the outer roller element 31.34 and the inner roller element 32.3. The roller elements 31 and 3 need to have the same shape, respectively.
It is not necessary that 4 be identical to roller element 32,33.

However, each roller element is required to have the same diameter at its narrow end.

The roller 2 is formed by sequentially arranging Seimei roller elements 31 to 34. In particular, the narrow end of the roller element 32 faces the narrow end of the roller element 31, then the wide end a of the roller element 33 faces the wide end a of the roller element 3□, and then the wide end a of the roller element 33 The narrow end of the roller element 34 is opposed to the narrow end of the roller element 34.

Therefore, on the sliding surface formed by the rollers 2, a gentle mountain shape is formed along the center line of the slideway, and furthermore, gentle valley portions are formed on both sides of the mountain shape.

(Effects) As detailed above, the present invention provides rollers constituting the sliding surface of a roller slide with a length of 80 to 120 mm, a diameter of 35 to 501 cm at the wide end a, and a diameter of 35 to 501 cm at the narrow end. 30~45s
It is formed using four roller elements that gradually become thinner from the wide end a to the narrow end a.

Therefore, on the sliding surface formed by the rollers 2, a gentle mountain shape is formed along the center line of the slideway, and furthermore, gentle valley portions are formed on both sides of the mountain shape. Moreover, the difference in height between the peaks and valleys is about 3 to 5 gI■, and the distance between the left and right valleys is 1
Since it is about 80 to 240 mm, the sliding surface will be a curved surface that matches the shape of your buttocks when you lower your back on it.
When you sit down in the center of this sliding surface, your buttocks will rest on the peaks and your thighs will be positioned in the valleys on either side.

Therefore, you will not feel any pain in your buttocks even if you slide down this sliding surface.

In addition, since the thighs are located in the valleys on the left and right, if the body leaks to either the left or right while downhill, the rider appears to be riding on the slope, and tends to try to slide down toward the valley. As a result, you will end up sliding down the center of the runway.

For this reason, by constructing the downhill surface using the rollers 2, it is possible to create a roller slide with a wide range of variations, such as by lengthening the downhill path, increasing the downhill speed, and curving the downhill course. It will become.
