Rod of an umbrella
A rod of an umbrella is a rod having a tail end and an extension rod having two ends; one end of the extension rod is detachably connected to the tail end of the rod; the rod is a hollow tube in which the extension rod is inserted, a limiting mechanism is located inside the rod for limiting insertion of the extension rod; the extension rod is made of rigid material or elastic material. When in use, the assembly can be completed by inserting the extension rod into the tail end of the rod, so that the rod becomes longer and is very easy to use. In the present invention, the rod is simple and reasonable in structure and easy and quick for operation and assembly, which can greatly increase the shading area, meet the functional requirements of the product, and reduce the packaging and transportation costs.
1. A rod of an umbrella, comprising:
a rod having a tail end; and
an extension rod having a main body, a first end, an opposite second end, and the second end having a circular coil;
wherein,
the extension rod is made of rigid material or elastic material;
an inserting section is formed by the first end of the extension rod;
the inserting section of the extension rod is detachably connected to the tail end of the rod,
the circular coil on the second end forms a turning end;
the elastic material comprises spring steel, glass fiber, carbon fiber, or plastic.
2. The rod of claim 1 , wherein the rod is a hollow tube in which the extension rod is inserted, a limiting mechanism is located inside the rod for limiting insertion depth of the extension rod.
3. The rod of claim 2 , wherein the limiting mechanism comprises a joint disposed inside the rod, the inserting section of the extension rod is inserted into the rod and is limited by resisting against the joint;
or the limiting mechanism comprises a fastener connected to the tail end of the rod, the inserting section of the extension rod is inserted into the rod and is limited by resisting against the fastener;
or the limiting mechanism comprises a recess located at a surface of the tail end of the rod, the inserting section of the extension rod is inserted into the rod and is limited by resisting against an inner sidewall of the rod corresponding to the recess.
4. The rod of claim 3 , wherein the joint located inside the tail end of the rod is hollow and has an open end and a closed end;
the closed end of the joint inserts inside the rod from the tail end of the rod, and the joint has a flange at the open end of the joint which rests against the tail end of the rod so that the flange of the joint is positioned at the tail end of the rod;
the inserting section of the extension rod is inserted into the joint and insertion of the extension rod is limited when the extension rod pushes against an inner sidewall of the closed end of the joint.
5. The rod of claim 3 , wherein the fastener is a rivet, a screw, or a pin radially running through the tail end of the rod, and insertion of the inserting section of the extension rod is limited by the fastener.
