DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an umbrella, and more particularly to an umbrella in which a part of a potter's wheel and bone members are made of synthetic resin.

[0002]

2. Description of the Related Art In recent years, many relatively inexpensive umbrellas have upper and lower potter's wheels and bone members partially made of synthetic resin. As this type of umbrella, for example, Japanese Utility Model 3-5528
No. 8 discloses a technique disclosed in Japanese Patent Publication No. In this umbrella, a receiving bone and a rib are integrally formed as a skeleton by using a synthetic resin. As shown in FIGS. 11 and 12 (a), an engagement formed at the tip of a receiving bone 51 of the skeleton. The part 51a is fitted into the groove 52a of the stator 52 (the upper potter's wheel).
As shown in (b), by rotating the receiving bone 51 by 90 ° around its axis, the enlarged portion 51b at the tip of the engaging portion 51a is locked in the hole 52b formed on the inner surface of the groove 52a. Thus, the parent bone portion 51 is connected to the stator 52. Similarly, the receiving portion of the skeleton is connected to the slider (the lower potter's wheel).

[0003]

The above-mentioned conventional umbrella is:
The frame can be easily connected to the stator and the slider, but if the frame receives a force in the torsional direction due to strong winds or the like, it rotates in the opposite direction to the direction of the connection and engages its tip. However, there is a problem that the connection is easily disconnected due to the part coming out of the groove of the stator or the slider.

On the other hand, in this type of umbrella, since the inner rod and the rib are often made of metal, a member made of synthetic resin and a member made of metal when discarded are used from the viewpoint of resource saving and pollution prevention. It is required to be easily decomposed so that can be separated and recovered.

It is an object of the present invention to provide an umbrella which is structurally stable and which can be easily assembled and disassembled.

[0006]

May be made of synthetic resin or metal.

In order to assemble the umbrella, first, the receiving bone 4 and the receiving bone 5 are connected to the upper and lower wheels 2, 3, respectively. As described with reference to FIGS. 5, 6, 8, and 9, the connection method is only to sandwich the inner ends of the receiving bone 4 and the receiving bone 5 between the two members 2 a, 2 b and 3 a, 3 b, respectively.
Easy to do. Next, as shown in FIG. 4, the receiving bone 4 and the receiving bone 5 are rotatably connected by pin connection. Then, the upper and lower wheels 2, 3 are slidably fitted to the center bar 1, and the upper wheel 2 is locked to the upper end of the center bar 1 as described with reference to FIGS. At this time, the handle 8 may be attached to the center rod 1 first. This mounting method can be made very simple as described with reference to FIG.

Next, the inner end of the rib 6 is inserted into the receiving hole 4 of the rib 4.
The cover sheet 7 is attached to the rib 6 by inserting the cap 9 over the upper end of the inner rod 1 and inserting the tip into the receiving hole 7b of the strip 7a while bending the rib 6. At this time, as shown in FIG. 7, the cap 9 prevents the stopper pin 10 inserted into the upper wheel 2 from coming off. When the lower wheel 3 is raised to a position where the lower wheel 3 is locked by the stopper 1b as shown in FIG. 2, the cover sheet 7 is expanded in a tensioned state by the elasticity of the rib 6, and the umbrella is opened.

When disassembling the umbrella, the above procedure may be reversed. First, when the tip piece 7a is pulled out from the tip of the rib 6, and the cap 9 is removed, the entire cover sheet 7 comes off the rib 6. Therefore, the parent bone 6 is extracted from the parent bone 4. Next, pull out the retaining pin 10 from the upper wheel 2,
The upper and lower potter's wheels 2 and 3 are removed from the center rod 1. Then, the retaining pin 11 is pulled out from the handle 8 and the handle 8 is removed from the center rod 1. As a result, the metal is separated into the inner rod 1 and the rib 6, the synthetic resin is divided into the upper and lower potter's wheels 2, 3 which are integrally connected, the ribs 4 and 5, the cover sheet 7, and the handle 8. In addition, even if a part of cloth or wooden material is used, incineration is possible and there is no pollution problem.

In the above-described embodiment, the upper wheel is formed integrally with the cylindrical member 2a and the epiphyseal receiving portion, and the lower wheel is formed into the cylindrical member 3a.
a and the lid are formed integrally, but if the receiving part and the lid are divided, either the receiving part or the lid may be used as the cylindrical member 2a, 3a
And may be formed integrally.

The upper and lower potter's wheels may be made of metal, and when they are separated, each of them may be disassembled into two members, and the connection with the synthetic resin receiving bone and the receiving bone may be released.

Furthermore, the assembly and disassembly of the umbrella is not limited to the above-described procedure, and it is also possible to assemble and disassemble in another procedure.

[0024]

As described above, according to the umbrella of the present invention, each of the rims provided on the outer periphery of the upper and lower potter's wheel sections is provided with a bone having a concave portion for receiving the parent bone or the enlarged diameter portion of the bone. Since it is divided into an end receiving part and a lid part for retaining the expanded part of the receiving bone or the receiving bone, it is possible to easily connect the upper and lower wheels with the receiving bone and the receiving bone, and The parent bone and the received bone do not come off from the potter's wheel during use, and can be used with confidence.

Also, since the umbrella can be easily assembled and disassembled, the umbrella can be separated and collected into a synthetic resin member and a metal member when discarded, which also contributes to saving resources and preventing pollution. is there.
