Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reinforcing member for a canopy.

[0002]

[Prior art]

 Conventionally, a metal member having a U-shaped cross section has been used as a rib of a western umbrella. In this case, a metal member formed in a U shape is weak against bending, and as a countermeasure, a reinforcing material made of resin containing fibers is fitted to a rib having a U shape in section to bend it. For improving the strength against the above, there are those proposed in, for example, Japanese Utility Model Publication No. 5-68319 and Japanese Utility Model Publication No. 5-93233.

[0003]

[Problems to be solved by the device]

 According to the proposal of Japanese Utility Model Laid-Open No. 5-68319, after connecting the reinforcing member to the rib, the connecting tool has to be wound to fix it. Further, according to the proposal of Japanese Utility Model Laid-Open No. 5-93233, after the reinforcing member is fitted to the rib, the reinforcing member has to be fixed by caulking. However, none of them could firmly and firmly fix the reinforcing member.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a reinforcing member for a canopy bone in which the reinforcing member can be easily fitted and held on the rib.

[0005]

[Means for Solving the Problems]

 The reinforcing member for the canopy bone according to the present invention has been made to solve the above-mentioned problems associated with the conventional technique, and is formed integrally with a rod-shaped main body made of fiber-reinforced resin and one end of the main body. The inner side wall of the main body is an extension of the bottom and both sides of the main body, and the cross-section has a U-shaped rib insertion hole, and the other end of the main body has a predetermined length. It is characterized in that the main body is formed integrally with the main body, and has a rib supporting portion having a U-shaped rib insertion hole whose inner wall surface is formed by extending both side surfaces and the bottom surface of the body.

[0006]

[Action]

 ADVANTAGE OF THE INVENTION According to the reinforcing member of the parabolic bone of this invention, the rear end of the rib is inserted from the front end side of the rib insertion hole formed in the rib connection part, penetrates the rib insertion hole, and the rib of the rib holding part. The reinforcing member and the rib can be integrally combined by inserting the rib into the insertion hole, penetrating it, and locking the rib to the bone connecting portion with the locking screw.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a reinforcing member for a canopy of the present invention, FIG. 2 is a front view, and FIG. 3 is a sectional view taken along line BB in FIG.

As shown in FIGS. 1 to 3, a reinforcing member 1 for a parachute bone according to the present invention comprises a rod-shaped main body 10 made of fiber-reinforced resin and a bone-retaining connecting portion formed at one end of the main body 10. 11 and a rib supporting portion 12 formed at a predetermined length from the other end of the main body 10 are integrally formed.

As shown in FIG. 4c, the main body 10 has a rod shape with a substantially quadrangular cross section, and is formed so that it can be fitted into a rib 31 having a U-shaped cross section shown in FIG. And, as shown in FIG. 4a, the skeleton connecting portion 11 has a bottom portion 10G integrally extending from the main body 10, and side pieces 11A and 11B extending upward from both sides of the bottom portion 10G, Mounting holes 11C and 11D are formed in the side pieces 11A and 11B, respectively, into which a pivot shaft 21 (FIG. 5) for attaching a bone is inserted. Further, the bottom portion 10G of the bone receiving connection portion 11 has side surface projections 11H and 11K projecting from the side surface of the main body, and lower projections 11J projecting from both sides and the bottom surface of the main body 10, and the lower projection 11J, U-shaped rib insertion holes 11F are formed in the side surface protrusions 11H and 11K, with the inner surfaces of the surfaces extending in the longitudinal direction on both sides and the bottom surface of the body 10 (see FIG. 4a). The front end of the bone receiving portion 11 has an extension 11M without side pieces, and a vertical hole 11G is formed in this extension (see FIGS. 3 and 4d).

Further, the rib supporting portion 12 has an upper surface, both side surfaces, and an upper surface protruding from the bottom surface, both side surfaces, and a bottom surface of the main body 10, and a surface obtained by extending the both side surfaces and the bottom surface of the main body 10 in the longitudinal direction. The rib insertion hole 12A having the inner wall is formed (see FIG. 4b).

Next, a usage state of the reinforcing member for the parabolic bone of the present invention will be described with reference to FIG. In FIG. 5, reference numeral 41 denotes a skeleton (also referred to as a skeleton), the tip of which is inserted into the middle 11E of both side pieces 11A and 11B of the skeleton connecting portion 11 of the reinforcing member 1 and rotatably attached by the pivot 21. Attach to holes 11C and 11D. Reference numeral 31 denotes a rib, which has a U-shaped cross section, and the rear end of which is inserted from the extension portion 11M of the rib connecting portion 11 of the reinforcing member 1 into the rib insertion hole 11F to pass therethrough and further pushed to the rib holding portion 12. Then, it is inserted into the U-shaped rib insertion hole 12A of the rib holding portion 12, penetrates the rib insertion hole 12A, and is brought into close contact with the side surface and the bottom surface of the main body 10.

Then, finally, the locking screw 22 is screwed into the screw hole 11 G of the bone receiving connection portion to lock the ribs 31. In this way, the main body 10 of the reinforcing member is closely fitted into the U-shaped recess of the rib 31.

The fiber used in the fiber-reinforced resin is preferably glass fiber or carbon fiber, and the resin is preferably polyethylene, polypropylene, polycarbonate or the like.

The pivot 21 may be a screw or a rivet, and the screw 22 may be a rivet.

[0015]

[Effect of device]

 Since the umbrella-reinforcing member of the present invention is configured as described above, the procedure of closely fitting the rib to the rib is simplified, and the efficiency of assembling the umbrella is improved.
