Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a canopy bone connecting member for improving the assemblability of the canopy bone and the service life of the canopy bone.

[0002]

Many bones are used in umbrellas and these bones are connected and assembled together. Therefore, in order to improve the productivity of the umbrella, it is desired to have a structure in which the bones can be easily connected and assembled. Further, since a considerably large force acts on the umbrella bone, the umbrella bone is required to have a considerable strength. In particular, this strength is concentrated on the above-mentioned connecting portion, so that the connecting portion of the umbrella frame is required to have both assemblability and strength.

As shown in FIG. 19, the connection between the ribs of the conventional umbrella and the ribs is divided into two ribs 1 and 2 as shown in FIG.
Bracket 5 which is connected to the connecting member 3 and is integrally provided on the connecting member 3.
The ribs 4 were connected to the ribs 1 and 2 through the rib connecting members 6 connected by the crimping pins 7 (Japanese Utility Model Publication No. 1-26259).

Further, FIG. 18 discloses a structure in which a main frame 8 and a support frame 4 are connected using a connecting member made of synthetic resin. In the connecting portion 9 between the two, the rib 8 is subjected to a bending process so that the rib 8 receives a force in the axial direction of the rib 4 (Japanese Patent Laid-Open No. 2-136104). Next, as shown in FIG. 17, there is disclosed a structure in which a connecting portion 10 is formed on the main rib 8 and the supporting rib 4 is connected to the connecting portion 10 by means of a caulking pin 7 (Shokai 61-60820). Bulletin).

[0005]

In the above conventional example,
In the structure shown in FIG. 19, since the ribs are divided into two, the number of ribs is doubled, and a lot of man-hours are required to connect to the connecting member, so that there is a problem that the assemblability of the umbrella bone is poor. Also, the figure
In the conventional example shown in FIG. 17 and FIG. 18, the rib is not divided into two, but a processing step of forming the connecting portion 10 and the curved portion at the connecting portion between the rib and the rib is required, and the productivity of the umbrella bone is increased. There is a problem with.

[0006] Next, regarding the strength, FIG. 17 and FIG.
In the structure shown in FIG. 19, all the axial force of the rib 4 is received by the caulking pin, so that the caulking pin is required to have a considerable strength, and there is a problem in terms of service life. Also, FIG.
In the structure shown in (1), the flexibility of the synthetic resin is used in the connection part to swing the bone while receiving the axial force of the bone, causing fatigue failure of the synthetic resin. There is a problem in terms of service life as well.

The present invention has been made in view of the above circumstances, and provides a umbrella-bone connecting member improved in assembly property and service life as compared with the conventional example.

[0008]

[Means for Solving the Problems] A first means according to the present invention for solving the above-mentioned problems is to provide a rib through hole for inserting a rib in the umbrella bone connecting member main body, and traverse the rib through hole. Forming an end fitting portion for locking the end portion of the notch bone in a substantially U shape, located at a lower portion of the rib through hole, and including the end fitting portion The bone-removing slits in which the bones locked to the end fitting portion can swing are provided in

A second means is to provide a rib through hole for inserting the rib through the main body of the umbrella connecting member, and communicate with a lower portion of the rib through hole to provide a space portion in a direction substantially orthogonal to the rib and receive the space. An end fitting part for locking the end part of the bone is formed, and the skeleton locked to the end fitting part is swingable so as to open the lower part of the end fitting part. It is characterized in that a bone receiving rocking slit is provided.

[0010]

Since the present invention is constructed as described above, first, when assembling the rib and the rib, the rib is inserted into the rib through hole after the end of the rib is locked to the end fitting portion of the connecting member. To do. By assembling the ribs and the ribs in this manner, the ribs prevent the end portions of the ribs that are locked to the end fitting portions from coming off. Since the ribs are inserted into the rib through-holes, it is not necessary to divide the ribs in two, and the rib material can be used as it is without any special processing. In this way, since the end of the skeleton is prevented from coming off by the rib and the end of the skeleton locked to the end fitting portion is rotatable within the end fitting portion, Swings in the slit with this end as a base point.

Next, the axial force of the rib is concentrated on the end portion of the rib which is locked to the end fitting portion. Then, this force is received by the end portion of the skeleton as a pressing force to the end fitting portion or the rib.

[0012]
