Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a bone receiving member according to the present invention, FIG. 2 is a cross-sectional view of a pull line shaft supporting portion of the bone receiving member shown in FIG. 1, and FIG. 3 is a bone receiving member relating to another embodiment. FIG. 4 is a cross-sectional view of the draw-line shaft support portion, and FIG. 4 is a cross-sectional view of the draw-line shaft support portion of the skeleton according to still another embodiment.

First, the skeleton 50 according to the present invention will be described with reference to the embodiment shown in FIGS. This rib 50 has a rib support 80 at one end of the rib main body 60,
The other end is provided with a hollow wheel shaft support portion 70, and a draw line shaft support portion 90 is provided between the rib support shaft portion 80 and the intermediate wheel shaft support portion 70.

Here, the skeleton main body 60 is formed of a round bar made of fiber reinforced plastic. Specifically, material: nylon resin containing carbon fiber, diameter: 3 mm, manufacturer: Toray Industries, Inc., product name: trading card, can be used.

Further, the rib supporting portion 80 and the inner lathe supporting portion 70 are made of a material: nylon resin containing glass short fibers Manufacturer: Toray Industries, Inc. Product name: nylon resin GM3001 It is what is molded.

Of course, the bone receiving main body 60 or the rib supporting portion 80 and the inner lathe supporting portion 70 may have other compositions. In addition, in the portion where the rib supporting shaft portion 80 and the inner potter wheel shaft supporting portion 70 of the bone receiving body 60 are integrally molded, the rib supporting shaft portion 80 and the inner potter wheel supporting portion 7 which are integrally molded are formed.
In order to prevent 0 from rotating with respect to the skeleton main body 60, a not-shown recess for preventing rotation is provided.

Further, the draw line shaft support portion 90 is formed by the bone receiving main body 60.
It is formed of a winding portion 91 wound around the wire and a lead wire support hole 92 for applying the lead wire 40. The winding portion 91 and the lead wire support hole 92 are formed integrally with the skeleton main body 60. Here, in the embodiment shown in FIG. 1, the winding portion 91 is formed so as to be continuous with the rib supporting portion 80 and the center wheel supporting portion 70. Therefore, in this embodiment, the bone receiving body 60
The whole is completely covered by the rib supporting portion 80, the winding portion 91 and the inner wheel supporting portion 70.

Further, in the rib 50, as shown in FIGS. 1 and 2, in the direction coinciding with the axis of the rib main body 60,
The winding portion 91 so that the protruding portion 93 is integrated with the winding portion 91.
It is provided at the bottom of. And, in this protruding portion 93,
The drawing line support hole 92 is provided so that the hole direction is orthogonal to the axis of the bone receiving main body 60. Therefore, unlike the draw line 40 that has been conventionally used for jump-type umbrellas, the rotation axes at both ends of the draw line 40 are also orthogonal.

However, as in this embodiment, if the rotary shafts at both ends of the drawing line 40 are provided so as to be orthogonal to each other, not only can the rotation of the drawing line 40 when the lowering wheel 11 or the like is moved accompanying the opening and closing of the umbrella, can be coped with. Even if the intermediate wheel 13 and the lower wheel 11 slightly rotate due to the compression or extension of the wheel spring 16, this rotation can be dealt with by the rotation of the draw line 40.

When the winding portion 91 is formed so as to be continuous with the rib supporting shaft portion 80 and the intermediate lathe shaft supporting portion 70 as in this embodiment, the load from the pull line 40 is applied to the winding portion 91 and the ribs 5.
In addition to being able to receive distributed load as a whole, a part of the load can be received on the rib support part 80 and the inner wheel support part 7.
It can be received at 0, and the rotational moment that causes the deflection is reduced. Furthermore, the bending of the entire skeleton 50 is reduced together with the fact that the skeleton 50 has a double structure and the bending stiffness represented by EI becomes large.

Of course, here, if the winding portion 91 is formed so as to be continuous with only the inner lathe shaft support portion 70, the entire winding portion 91 on the inner ladle side of the rib 50 receives the load from the lead line 40. Not only this, but also the fact that a part of the load is received by the center wheel and shaft support 70 reduces the rotational moment that causes bending. Furthermore, the bending of the skeleton 50 as a whole can be reduced together with the fact that the winding portion 91 of the skeleton 50 has a double structure and the bending stiffness represented by EI becomes large.

Further, the winding portion 91 can be formed so as not to be continuous with the rib supporting portion 80 and the inner potter wheel supporting portion 70 in the bone receiving main body 60. That is, the skeleton main body 60 in the vicinity of the protruding portion 93 provided with the lead wire supporting hole 92
This is a case in which the winding portion 91 is provided only on. Even in this case, since the load applied to the lead wire support hole 92 becomes a distributed load due to the winding portion 91 of the predetermined length provided in the bone receiving main body 60, the deflection of the entire bone receiving bone 50 is reduced. Will be done. Further, the portion of the rib 50 where the winding portion 91 is provided has a double structure, and the bending stiffness represented by EI becomes large, so that the flexure of the entire rib 50 can be reduced.

When the winding portion 91 is formed of a material having a large longitudinal elastic modulus represented by E, the winding portion 91 is less likely to bend and the flexure of the entire rib 50 is reduced.
In the case where the winding portion 91 is formed so as to be continuous with the hollow and cross shaft support portion 70, or when the winding portion 91 is formed so as not to be continuous with the rib support shaft 80 and the cross wheel shaft support portion 70, A concentrated load will be applied to the end portion of the mounting portion 91.

On the other hand, if the winding portion 91 is made of a material having a relatively small longitudinal elastic modulus, which is represented by E, the winding portion 91 is formed continuously with the center lathe shaft supporting portion 70, or the winding portion 91 is formed. The winding portion 91 when it is formed so as not to be continuous with the rib supporting portion 80 and the center wheel supporting portion 70.
Although it is difficult to apply a concentrated load to the ends of the, it will be more flexible than the one with a large longitudinal elastic modulus. However, even in this case, the deflection is much reduced as compared with the case where the winding portion 91 is not provided.

Next, the draw wire shaft support portion 90 shown in FIG. 3 will be described. In the rib 50, the protruding portion 93 is the winding portion 9
It is provided so as to integrally project with 1 downward. The projecting portion 93 is provided with a lead wire support hole 92 such that the hole direction is parallel to the axis of the bone receiving main body 60. In this way, if the draw wire support hole 92 is formed so that the hole direction is the same direction as the bone receiving main body 60, the draw wire 40 is formed.
Since the rotary shafts at both ends are parallel, the draw line 40 that has been used conventionally can be used as it is.

Further, the draw line shaft support portion 90 shown in FIG. 4 will be described. In the rib 50, the protruding portion 93 is provided on the upper portion of the winding portion 91 so as to be integrated with the winding portion 91 in a direction coinciding with the axis of the rib main body 60. In the projecting portion 93, the lead wire support hole 92 has a hole direction orthogonal to the axis of the bone receiving body 60, and the lower inner surface of the lead wire support hole 92 is substantially flush with the surface of the winding portion 91. It is provided so that.

Therefore, unlike the draw line 40 that has conventionally been used for jump type umbrellas, the rotation axes at both ends of the draw line 40 are also orthogonal. However, if it is provided so that the rotation axes of both ends of the draw line 40 are orthogonal to each other, not only can the rotation of the draw line 40 during movement of the lathe, etc., which accompanies the opening and closing of the umbrella, be accompanied by the compression or extension of the potter's wheel spring. Even if the center wheel and the lower wheel slightly rotate, this rotation can be dealt with by the rotation of the draw line 40.

Further, in the lead wire support hole 92 shown in FIG. 1, FIG. 2 or FIG. 3, it is possible that the projection 93 below the lead wire support hole 92 is damaged by the load from the lead wire 40. In the embodiment shown in FIG. 4, since the winding portion 91 is formed so as to directly receive the load from the lead wire 40, there is no damage due to the load from the lead wire 40. In the above description, it is sufficient that the lead line support hole 92 has a shape such that the lead line 40 does not come off when the jump type umbrella is opened and closed.

Although the bone receiving body 60 is shown as a cylinder,
Not only can it be a square prism or a polygonal prism,
It is also possible to use a column having a sectional shape such that the second moment of area represented by I becomes large. Similarly, the winding section 9
1 also has a cylindrical shape because the bone receiving main body 60 is shown as a column, but when it is molded around the bone receiving main body 60, the winding shape is changed along with the change in the cross-sectional shape of the bone receiving main body 60. The sectional shape of the mounting portion 91 also changes. Further, for example, although the skeleton main body 60 has a cylindrical shape, the winding portion 91 is provided so that the outer shape resulting from the provision of the winding portion 91 becomes a square pole shape, or the outer shape has a gate shape.
It can also be shaped like a letter.

That is, the winding portion 91 can increase the secondary moment of area represented by I of the entire skeleton 50 to make it difficult to bend. Furthermore, this winding part 9
1 does not need to be formed so as to be integrated with the bone receiving main body 60, or need to be formed so as to be completely wound around the bone receiving main body 60. For example, even if the winding portion 91 is provided such that the lower surface of the skeleton main body 60 is partially exposed, it is sufficient if the bending of the skeleton 50 as a whole can be reduced.
