- FIG. 2B is a partial cross-sectional view illustrating the flexible tube 100 shown in FIG. More specifically, it is a partial cross-sectional view in which the right two of the upper three cross-sectional views shown in FIG. As shown in FIGS. 1 and 2A, a part of the flexible tube 100 is cut away so that the internal configuration of the flexible tube 100 can be seen.
- the flexible tube 100 is formed by spirally winding a single wire 110 as shown in FIG. Specifically, as shown in FIGS. 2A and 2B, one end 111 in the longitudinal direction of the wire 110 is bent into an inverted R shape. On the other hand, the other end 112 in the longitudinal direction of the wire 110 is bent in an inverted J shape. And the front-end
- a wire may be called a board
- both ends of the flexible tube 100 are gripped in FIG. 2A and the flexible tube 100 is bent so that both ends are directed downward in FIG. 2A, the outer side of the bent flexible tube 100 is obtained.
- the tip of the other end 112 ′ moves in the direction of exiting from the internal space formed by the inverted R-shaped one end 111 while maintaining the state of being sandwiched between the gaps 111a.
- the tip of the other end 112 ′′ that is inside the bent flexible tube 100 enters the inside formed by the inverted R-shaped one end 111 ′ while maintaining the state of being sandwiched by the gap 111b. Move in the direction.
- the tip of the other end 112 ′ is maintained in the state of being sandwiched by the gap 111 a, and the tip of the other end 112 ′′ is sandwiched by the gap 111 b. Therefore, the shape of the flexible tube 100 is maintained in a bent state.
- the wire 110 is wound spirally, the other end 112 ′′ turns to the back side of the paper surface and corresponds to the other end 112 ′.
- the one end 111 ′ turns to the back side of the paper surface and corresponds to the one end 111.
- a gap 111c is formed between the outside of the inverted R-shaped one end 111 and the outer periphery of the wire 110 adjacent by winding.
- a packing 120 is inserted into the gap 111c. Waterproofness is ensured by the packing 120. That is, even if a liquid such as water or hot water flows in the flexible tube 100, liquid leakage can be prevented. Examples of the packing 120 include cotton yarn and rubber. The packing 120 may not be inserted depending on the usage application of the flexible tube 100.
- a flexible tube having a perfectly circular cross section should be spirally wound around a shaft (not shown) whose cross section is a perfect circle while maintaining the meshing between the wire and the adjacent wire. It is formed by. Then, the shaft is pulled out when the flexible tube reaches a certain length. Thereby, the cross-section perfect circle type flexible tube which has fixed length is completed.
- the cross-sectional shape of the flexible tube is preferably a true circle as much as possible, but may be a substantially round shape including errors. Since the shaft according to the internal diameter of a flexible tube is utilized in the case of winding, the flexible tube which has various internal diameters is completed.
- cables as solids may pass in place of the liquid described above. Examples of the cables include a communication line such as an optical fiber and a communication cable, and an energization line such as an electric cord.
- FIG. 3 is a front view illustrating an interlock type flexible tube 100. More specifically, FIG. 3 shows a front view seen from the direction of arrow B in FIG.
- FIG. 4 is a cross-sectional view illustrating an interlock type flexible tube 100. More specifically, FIG. 4 schematically shows a cross section viewed from the direction of arrow C in FIG.
- the flexible tube 100 has an elliptical cross-sectional shape in the direction in which a liquid or solid passes.
- the cross-sectional shape of the flexible tube 100 is preferably a true oval shape as much as possible, but may be a substantially oval shape including errors.
- the flexible tube 100 having an elliptical cross-sectional shape is obtained by placing a flexible tube having a perfect circular cross-sectional shape on a flat mounting table 130 and, as shown by an arrow P in FIG. It is formed by pressing with a uniform force. That is, the flexible tube whose cross section is a perfect circle is crushed and deformed, and the flexible tube 100 whose cross section is elliptical is obtained.
- one side surface of the flexible tube having a perfect circular cross section may be applied to a flat surface and pressed from the other side surface.
- the flexible tube 100 having an elliptical cross section may be completed by a single press or may be completed by a plurality of presses.
- the elliptical shape is the twisting force of the flexible tube having a perfectly circular cross section when twisted in the winding direction of the wire 110 or in the opposite direction.
- the concentrated portion has a shape that makes it difficult to transmit the torsional force generated by being twisted.
- the flexible tube 100 having an elliptical cross section even when the wire 110 is twisted in the winding direction or in the opposite direction, the holding force for maintaining the shape is strengthened.
- the interlock type flexible tube 100 has been described above, the twisting force is hardly transmitted to the concentrated portion for the same reason for the semi-interconnect type. As a result, torsional breakage from the concentrated portion is less likely to occur. That is, if it is a semi-inter type, the flexible tube 100 strong against torsional fracture is obtained.
- the semi-inter type is formed by firmly engaging a U-shaped one end formed by bending a wire and an adjacent U-shaped other end wound around.
- the semi-inter type there is no gap in the meshing part as in the interlock type, or the holding force for holding the shape is not exhibited due to the extremely small gap compared to the interlock type, but as described above, Not only has a strong property against twisting, pulling and pressing from the side, but also flexible flexibility is ensured.
- the space inside and outside the flexible tube is ensured by making the cross-sectional shape elliptical.
- a flexible hose H1 in which a coating 200 having a cross section of a perfect circle and a diameter larger than the major axis of the ellipse is applied around the interlock type flexible tube 100. Then, a space is formed between the minor axis of the ellipse and the coating.
- the coating include synthetic resins such as PVC (Polyvinyl Chloride), polyolefin, and silicon.
- a space is formed between the major axis of the ellipse and the inner tube.
- the space formed in this way may be used to pass at least one cable 300 such as the communication line or the energization line described above.
- power is supplied to a component around the water attached to one end of the flexible tube, or an instruction is given to the control device attached to the other end of the flexible tube by operating the component at hand. be able to.
- a portion of the space where the cables 300 are removed may be filled with a resin so as to prevent displacement of the cables 300. If the space through which the cables pass is secured, the ratio of the major axis to the minor axis of the elliptical shape can be arbitrarily determined.
- the winding direction described above is described as the direction in which the wire 110 is wound around the shaft (direction in which the inner diameter is reduced), and the reverse direction of the winding direction is described as the direction in which the wire 110 is unwound from the shaft (direction in which the inner diameter is expanded). .
