Problems solved by technology

Since the mating operation can forcefully fasten the small protrusion with the inclined surface on the opposite side through a short time and short stroke, although it is more difficult to cause the fixation phenomenon compared with the case where no small protrusion is formed, it cannot be released at the moment of mating operation. The state of crimping needs to be improved on the mating part

no. 1 Embodiment approach

[0051] A description will be given of the structure mainly applied to the intermediate rods from the second rod on the drawer rod A to the second rod from the bottom, especially the fourth rod to the middle rod on the large diameter side. The rod body on the small-diameter side will be described as the small-diameter rod body 1 , and the rod body on the large-diameter side will be described as the large-diameter rod body 2 .

[0052] Not shown, the production process of the rod body is as follows: that is, the reinforcement fibers such as carbon fibers are arranged along one side, and the arranged reinforcement fibers are soaked in thermosetting resins (or thermoplastic resins) such as epoxy resins to form Preforms. The preform is cut according to the specified shape and then wound onto the mandrel, and then the product after several layers of winding is fired, cut into a specified length after firing, and then subjected to subsequent processing to form a rod body.

no. 2 Embodiment approach

[0084] Here, at the butt end of the rod body 1 on the small diameter side, although the number of protrusions 1a provided is arbitrary, FIG. 8 shows that four protrusions 1a are provided at four positions along the circumferential direction.

[0085] Even if only the protruding portion 1a is formed, the contact between the protruding portion 1a and the inclined guide surface 2C and the straight cylindrical portion 2B formed at the rod body 2 on the large-diameter side provides a good fit for the fisherman during operation. sense of operation.

[0086] (third embodiment)

[0087] Shown is the state where the forming objects of the protruding part and the straight cylindrical part are exchanged. Such as Figure 10 As shown in (a), an inclined abutment surface 1A is formed on the outer peripheral surface of the butt end of the rod body 1 on the small diameter side in the same manner as in the case of the first embodiment. Straight cylindrical part 1C.

[0088] On the other ha...

no. 4 Embodiment approach

[0091] Although the protruding parts 1a and 2E are formed as parts in contact with the straight cylindrical part on the opposite side, as shown in Fig. A flange-like protruding portion 1D may also be provided. That is, the flange-shaped projecting portion 1D is formed so that the outer peripheral surface of the flange-shaped projecting portion 1D is in contact with the straight cylindrical portion 2B of the rod body 2 on the large-diameter side. In order to elastically contact the flange-shaped protrusion 1D with the straight cylindrical portion 2B, a plurality of cutting grooves 1d extending radially to a certain depth may be provided on the outer peripheral surface of the flange-shaped protrusion 1D along the circumferential direction. Thereby, the contact pressure of the flange-shaped projecting portion 1D and the straight cylindrical portion 2B can be slightly reduced and substantially uniform.

Abstract

The invention provides a telescopically extensible rod reduced in fabrication charge and capable of preventing locked state. A joint part B for retaining a small diameter side rod body 1 in an extended state to a large diameter side rod body 2 is composed of a straight cylinder part 2B formed on the large diameter side body 2 and having a contact surface keeping a constant diameter, and projection surface parts 1a formed on the small diameter side rod 1 and contacting with the contact surface of the straight cylinder part 2B. The surface layer of the straight cylinder part 2B composed by piling a prepreg having a reinforcing fiber c group extendedly arranged and set along a fixed tilt angle [theta] to a rod axis X, and a prepreg having a reinforcing fiber c group extendedly arranged and set in a state symmetrical with the reinforcing fiber group of the prepreg and the rod axis X. The surface layer of the projecting parts 1a is composed of a prepreg obtained by impregnating a resin to a reinforcing fiber c group extendedly arranged and set along the rod axis X direction.

Description

technical field [0001] The present invention relates to a drawer rod provided with a fitting part capable of switching between a state in which a small-diameter rod body is accommodated inside a large-diameter rod body and a state in which the small-diameter side rod body is drawn out from the large-diameter rod body, Also, it keeps the rod drawn out and extended. Background technique [0002] The fitting portion is structured as follows: an inclined surface that is pressed against each other is formed on the outer peripheral surface of the butt side end of the rod body on the small diameter side and the inner peripheral surface of the front end of the rod body on the large diameter side. The elongated state of the rod body on the small diameter side is maintained by the pressing between the slopes. [0003] When adopting such a structure and maintaining the elongated state of the rod body on the small diameter side in this pressed contact state, if moisture or the like exi...
