说明书全文 | The present invention relates to a safety umbrella runner. A conventional lower runner 4 as shown in Figure 1 is slidably held on a central shaft 1 of an umbrella having a rib assembly 2 with a top rib 21 and a stretcher rib 22 respectively pivotally secured to an upper notch 3 and the lower runner 4, which however has the following drawbacks:
The present inventor has found the drawbacks of the conventional umbrella runner and invented the present safety umbrella runner. According to the present invention, there is provided an umbrella lower runner having a spring button plate integrally formed with the runner normally extending outwardly for shielding a spring catch resiliently held in a central shaft of the umbrella and operatively depressed for depressing the spring catch for lowering the runner for closing the umbrella, so that the depression of the spring button plate on the spring catch will not injure a user's fingers for safety purpose. Embodiment of the present invention will be described with reference to the accompanying drawings, in which:
As shown in Figures 2, 3, the present invention comprises: a lower runner 4 slidably held on a central shaft 1 of an umbrella which includes a rib assembly 2 secured with an umbrella cloth having a plurality of top ribs 21 pivotally secured to an upper notch 3 fixed on a top portion of the shaft 1, and a plurality of stretcher ribs 22 each rib 22 pivotally secured between the lower runner 4 and each top rib 21, a spring catch 5 resiliently held in the shaft 1 for retaining the runner 4 when extending and opening the umbrella, and a grip 11 formed on a lower end portion of the shaft 1. The lower runner 4 includes: a lower periphery 41 formed on a lower portion of the runner 4 resiliently held on the spring catch 5 for extending or opening the umbrella of the present invention as shown in Figure 2, a middle ferrule flange 40 formed on a middle portion of the runner 4 having a ring-shaped wire 42 circumferentially wound on the ferrule flange 40 for pivotally mounting each stretcher rib 22 thereon in which a knot 43 is tied at two free ends of the wire 42, a spring button plate 44 integrally formed on the runner 4 by protruding outwardly upwardly from the lower periphery 41, a slot 45 which is directly cut in the runner 4 for forming the spring button plate 44 and prejectively disposed around the button plate 44, a pair of shielding protrusions 46 integrally formed on the runner 4 disposed on a right and a left side of the knot 43 for preventing injury to a user, and a central hole 47 formed through the runner 4 for slidably holding the runner 4 on the central shaft 1. The spring button plate 44 of this invention is designated "spring" because the plate 44 is directly formed on the runner 4, which may be made of plastic materials having suitable elastic property, by cutting the slot 45 in the runner 4. The catch 5 is extended outwardly from the shaft 1 to engage the slot 45 so that the runner 4 and the rib assembly 2 can be stably held on an upper portion of the central shaft 1 when extending the rib assembly 2 and opening the umbrella of the present invention. The outwardly protruded spring catch 5 is shielded and protected by the button plate 44. When it is intended to close the umbrella which had already been opened as shown in Figure 2, the spring button plate 44 is depressed in direction D as shown in Figure 2 to depress the catch 5 inwardly to disengage the runner 4 from the catch 5 so as to lower the runner 4 and retract the ribs 2 for closing the umbrella. Since the thin-plate catch 5 is shielded by the button plate 44, the depression of catch 5 is indirectly done by the user because the catch 5 is depressed inwardly as urged by the button plate 44 when depressed by the user, so that a user's finger will not contact the thin-plate catch 5 to prevent any injury caused to the user. The present invention is superior to any conventional umbrella runner with the following advantages:
