Abstract

PURPOSE:To prevent causing pain to a kidney portion when a user slides down on a slide by causing a portion of an outer tube to sink when an external force above a predetermined level is applied to the tube so as to absorb the external force, and forming a stopper between an inner pipe and the outer tube in order to regulate the amount by which the outer tube sinks. CONSTITUTION:A roller element 3 consists of an outer tube 31, an inner pipe 32 and a connecting member 33 for connecting the tube 31 and the pipe 32 to each other, all of which are integrally molded from a material with proper elasticity and abrasion resistance and weather resistance such as nylon and the like. The outer tube 31 is 50 to 120mm long and 35 to 50mm in diameter and 2 to 4mm or so in plate thickness and forms the outer shape of the roller element 3 and when an external force A above a predetermined level is applied the outer shape sinks and absorbs the external force. The bore of the inner pipe 32 is almost the same as the diameter of a support shaft 4 and is fitted into the support shaft 4 to keep the outer tube 31 at a predetermined portion of the support shaft 4. The connecting member 33 connects the outer tube 31 to the inner pipe 32 and keeps both of them in a double structure and is molded integrally with both of them.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a roller element constituting a roller of a roller slide.

(Prior Art) In recent years, roller slides have been used for many slides.

This roller slide has a large number of freely rotating rollers constructed by loosely fitting roller elements with a length of 50 to 120 am and a diameter of 35 to 50 mm on a spindle.
These are placed side by side between the left and right side plates and have 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.

(Problems with the prior art) The free-rotating rollers of the roller slide described above must be made of a material with excellent abrasion resistance and weather resistance, such as nylon, and are therefore too hard. He had a problem where he felt pain.

An object of the present invention is to provide a roller element that does not impair predetermined abrasion resistance, weather resistance, etc., has a more flexible appearance, and does not cause pain to the buttocks, etc. when sliding down. shall be.

(Means for Solving the Problems) A roller element for a slide according to the present invention is composed of an outer tube, an inner tube, and a connecting member that connects the two, and is made of nylon or the like having appropriate elasticity. It is integrally molded using materials with wear resistance, weather resistance, etc.
When an external force exceeding a predetermined value is applied to the outer tube, that part deforms to absorb the external force, and a stopper is formed between the inner tube and the outer tube to restrict the amount of deformation of the outer tube. The above-mentioned problem is solved by the means configured as follows.

The connecting member is provided at any position of the roller element,
It is possible to control the part of the outer cylinder that deforms, and it also has deformability to itself. It is also possible to deform all parts of the outer cylinder by applying pressure.

The stopper can function as a rib of the outer tube and inner tube.

(Function) The roller element for a slide according to the present invention is composed of an outer tube, an inner tube, and a connecting member that connects the two, and by imparting deformability to the outer tube, the outer tube can be subjected to an external force of more than a predetermined value. When an external force is applied, that part deforms and absorbs the external force, alleviating the impact on the buttocks and the like.

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

FIG. 1 shows a longitudinal 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 consists of a pair of left and right side plates 1 and a large number of freely rotating rollers 2. The free rotating rollers 2 are made up of several roller elements 3 loosely fitted onto a support shaft 4, which are connected to the side plates 1. .1 are installed at regular intervals to form a sliding surface.

The roller element 3 consists of an outer tube 31, an inner tube 32, and a connecting member 33 that connects the two, and these are made of materials such as nylon that have appropriate elasticity, wear resistance, weather resistance,
It is integrally molded using a material that has properties such as properties.

The outer cylinder 31 has a length of 50 to 120 mm and a diameter of 35 to 50 mm.
The outer cylinder 31 has a wall thickness of about 2 to 4 m and constitutes the outer shape of the roller element 3, and when an external force exceeding a certain level is applied, that part becomes flat or the outer cylinder 31 itself curves. It deforms and absorbs that external force.

The inner tube 32 has a tubular shape with the same inner diameter as the diameter of the support shaft 4, and is fitted onto the support shaft 4 to maintain the outer cylinder 31 at a predetermined position on the support shaft 4. There is.

The connecting member 33 connects the outer w31 and the inner tube 32, and is integrally molded with both.

A stopper 34 is formed on the inner tube 32, so that the apparent upper distance between the outer tube 31 and the inner tube 32 is narrowed, so that even if a strong external force is applied to the outer tube 31, this distance remains constant. It is designed not to deform beyond this point. Although the figure shows an example in which the stopper 34 is formed on the inner tube 32, the stopper 34 is not limited to this. It can also be formed on the inner surface of the outer tube 31, or the stopper 34 can be formed on the inner tube 32 and the outer tube 31. It can also be formed oppositely. Since this stopper 34 inevitably functions as a rib, the position where it is formed is determined in consideration of this point.

The embodiment shown in FIG. 2 shows an example in which the connecting member 33 is formed at a position biased to one side of the roller element 3. In this embodiment, the outer cylinder 31 is arranged on the side where the connecting member 33 is formed and on the opposite side. The ease of deformation (the apparent flexibility) differs depending on the side.

That is, the roller element 3 hardly deforms due to external force on the side where the connecting member 33 is formed, and becomes more easily deformed as it approaches the opposite side. Therefore, this roller element 3 is suitable for a slide in which a freely rotating roller 2 is constituted by four roller elements as shown in FIG.

In the embodiment shown in FIG. 3, the connecting member 33 is curved to give it appropriate deformability, and
This shows an example in which this is formed in the center of the roller element, and each part of the roller element 3 has a sea-like deformability.

(Effects of the Invention) As described in detail above, the present invention comprises a free rotating roller that constitutes the sliding surface of a roller slide by a roller element consisting of an outer tube, an inner tube, and a connecting member, and the outer tube has deformability. , and when an external force is applied to this part, 1. ′-reflects and absorbs the external force.

As a result, the rollers appear to be more flexible, and you won't feel any pain in your buttocks when you slide down this sliding surface, making the slide even more effective.
