Base of sunshade umbrella

Abstract

The present utility model is a large-sized sunshade umbrella which is used at fixed site outdoor. The interior of the base is divided into several independent portions, a protection case which is mated with the base is brought to cover the base, and the devices of caster wheel which can be stretched-out and drawn-back are provided in the holes at the corners of the base. Sand or water as the counterweight in the base can be added or reduced freely. When the base needs to fix, the caster wheels are drawn-back into the base through manual regulation to make the base rest on the ground to increase the attaching force; when the umbrella needs to move, the four caster wheels are stretched-out from the base to contact with the ground, so that a man or woman can push the umbrella smoothly to the site where he or she intends to place it.

Description

DESCRIPTION OF THE INVENTION [0001] 1. Field of the Invention [0002] The present utility model relates to a large-sized sunshade umbrella used at fixed site outdoor, in particular, to a base of the sunshade umbrella. [0003] 2. Background of the Invention [0004] A large-sized sunshade umbrella used at fixed site outdoor, in particular a pendent umbrella, has very poor steadiness, because its umbrella face is so large as to catch wind easily. In order to steady an umbrella as a whole, its base must be very heavy in weight or have a large counterweight. A base of sunshade umbrella with a conventional structure has some problems, for example, its counterweight can not be regulated arbitrarily to make the base difficult to be attached to the ground more firmly; the umbrella as a whole is too heavy to move at will, etc. SUMMARY OF THE INVENTION [0005] The object of the present utility model is to overcome the defects of the prior art and provide a base of umbrella, as a result, not only i...

AI Technical Summary

Benefits of technology

[0011] The advantageous effects of the present utility model are as follows: sand or water as the counterweight of the base can be added or reduced freely; when the base needs to fix, the caster wheels are drawn-back into the base through manual regulation so as to make the base rest on the ground to increase the attaching force; when the umbrella needs to move, the four caster wheels are stretched-out from the base to contact with the ground, so that a man or woman can push the umbrella smoothly to the site where he or she intends to place it.

[0012] Additional objects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims.

[0013] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

Problems solved by technology

A large-sized sunshade umbrella used at fixed site outdoor, in particular a pendent umbrella, has very poor steadiness, because its umbrella face is so large as to catch wind easily.

A base of sunshade umbrella with a conventional structure has some problems, for example, its counterweight can not be regulated arbitrarily to make the base difficult to be attached to the ground more firmly; the umbrella as a whole is too heavy to move at will, etc.
