Benefits of technology

[0003] The present invention is to provide an engaging structure for runner of an umbrella, in which the runner can be engaged around the shaft without the prior spring bow. Hence, it can be manufactured in ease and will be utilized for people to use conveniently. Now, accompanying with the following drawings, the character of the present invention will be described here and after.

Problems solved by technology

The manufacturing procedure for mounting the spring bow in the shaft is very difficult and the strength of the shaft will be decreased while it is formed a slot thereon.
Moreover, the spring bow may clip user's finger when he is closing the umbrella.

Embodiment Construction

[0011] Referring to FIG. 1 to 3, the present invention is to provide an engaging structure for runner of an umbrella, wherein the runner (1) has been provided with several side apertures (11) for receiving a relating ball (12). A sleeve (2) is provided around the runner (1), which includes upper opening (22) and an inner middle edge (21) having smaller diameter relating to the opening (22). The sleeve (2) has an inner low projective ring (23), which can engage with a positioning ring (13) on the runner (1) thereunder. The runner (1) with the sleeve (2) is provided around shaft (3) having an annular convex portion (31).

[0012] When to open the umbrella while the runner (1) is moved upward to the position of FIG. 4, the runner (1) cannot be moved but the sleeve (2) can be moved upward a little distance to force the projective ring (23) sliding cross the positioning ring (13) and the middle edge (21) compressing the balls (21) falling into the convex portion (31) of the shaft (3). That...

Description

FIELD OF THE INVENTION [0001] The present invention relates to an umbrella having the runner, which can be positioned at the place to maintain the umbrella being opened by a novel and improved structure. BACKGROUND OF THE INVENTION [0002] It is known that an umbrella includes a runner for controlling umbrella frame to be opened or closed. In order to keep the umbrella at opening state, a spring bow is applied within shaft for stopping the runner at upper position around the shaft. The manufacturing procedure for mounting the spring bow in the shaft is very difficult and the strength of the shaft will be decreased while it is formed a slot thereon. Moreover, the spring bow may clip user's finger when he is closing the umbrella. SUMMARY OF THE INVENTION [0003] The present invention is to provide an engaging structure for runner of an umbrella, in which the runner can be engaged around the shaft without the prior spring bow. Hence, it can be manufactured in ease and will be utilized fo...
