Gear-Type Umbrella Runner

FIELD OF THE INVENTION

The invention belongs to the field of parasol umbrella and specifically provides a gear-type umbrella runner.

BACKGROUND OF THE INVENTION

Runners and poles are coordinately used in many fields, especially in the field of parasol umbrella. Traditional runners are designed relatively moving along poles in the means of pushing or pulling. The pushing and pulling structure is quite complicated, costs more to manufacture and brings no user friendliness while in use.

SUMMARY OF THE INVENTION

In view of the problems in the prior art, the invention provides a gear-type umbrella runner.

The claimed gear-type umbrella runner, wherein a handle is configured on the runner; a gear is configured inside the runner; the handle is coaxially connected with the gear; the gear is connected with the pull rod; the movement of the pull rod is driven by the rotation of the gear.

The claimed gear-type umbrella runner, wherein a spring is configured between the pull rod and the internal side wall of the runner.

The claimed gear-type umbrella runner, wherein the handle is in a pentagonal shape.

The gear-type umbrella runner of the invention features simple structure, low manufacturing cost and ease and convenience in use. It is applicable to all fields that need runners, especially to parasol umbrella.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic diagram of a gear-type umbrella runner.

FIG. 2 is an internal structure diagram of a gear-type umbrella runner.

Wherein: 1. pole; 2. runner; 3. handle; 4. pull rod; 5. gear; 6. spring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the drawings, the invention is further described as:

As shown in FIG. 1 and FIG. 2, a gear-type umbrella runner is provided. A pentagonal handle 3 is configured on the runner 2; a gear 5 is configured inside the runner 2; the handle 3 is coaxially connected with the gear 5; the gear 5 is connected with the pull rod 4; the movement of the pull rod 4 is driven by the rotation of the gear 5; a spring 6 is configured between the pull rod 4 and the internal side wall of the runner 2. The gear 5 can be connected with the pull rod 4 in all regular means, for instance, by configuring a compatible tooth on the pull rod 4 to engage the gear 5, or connecting the gear 5 with the pull rod 4 through a poke block or a connecting rod, and etc. While in use, simply rotating the handle 3 to drive the rotation of the gear 5 and the movement of the pull rod 4 to move away from the positioning hole in the pole 1 can enable the runner 2 to slide relatively to the pole 1; positioning can be realized by simply moving the runner 2 to the relevant position to enable the pull rod 4 to be ejected by the reset spring 6 into the positioning hole in the pole 1.

The forgoing are some preferred embodiments of the invention which, however, is not limited to the embodiments. The changes, equivalent modifications and improvements that fall within the true spirit and scope of the invention shall be covered by the invention.
