Embodiment Construction

[0025] figure 1 An exploded view of an umbrella shaft is shown having a lower shaft portion 10 and an upper shaft portion 14 on which a slip ring 12 is slidably mounted. For convenience, the terms "above" and "below" with respect to the shaft portion refer to the orientation of the umbrella in normal use; they should not be construed as limiting the spatial position. exist figure 1 In the umbrella shown, after assembly, the upper shaft portion 14 of the umbrella shaft is mounted on the lower shaft portion 10 of the umbrella shaft and is tiltable relative to the lower shaft portion.

[0026] The slip ring 12 includes a slip ring body 16 , an annular lock 18 with a button 20 , and a notch ring 22 . The end of the slip ring body 16 is annular, and one or more tabs 24 are provided at the end of the upper shaft part 14 near the umbrella shaft on its inner surface; the end of this slip ring body can also be a cam Shaped. exist figure 1 In the assembled umbrella shown, the ribs ...

Abstract

An umbrella frame has an umbrella shaft divided into two parts, a lower shaft part (10) and an upper shaft part (14), on which a slip ring (12) is slidably mounted. After assembling, the upper shaft part (14) of the umbrella shaft is installed on the lower shaft part (10) of the umbrella shaft, so that when the sliding ring is rotated after the umbrella frame is opened, the upper shaft part can be inclined relative to the lower shaft part. When the frame is in the open position, the slide ring is engageable with a rotating member (34) having a helical thread (36). The thread engages a tooth (30) on a tooth (28) which is connected to the upper shaft portion of the umbrella shaft. Rotation of the swivel causes the teeth to straddle the threads, which causes the upper shaft section to tilt. This allows the user to tilt the umbrella simply by rotating the slide ring.

Description

technical field [0001] The present invention relates to an umbrella used for sun protection, wind and rain protection, which has a step-by-step tilting mechanism, by which the top of the umbrella can be positioned at a desired position; this umbrella can be used as an umbrella for fishing or Parasols for cafes. Background technique [0002] In prior art tilting mechanisms, the tilting action takes place when the slide ring reaches its top position, ie the umbrella is fully extended. At this point, further movement of the slide ring along the shaft engages another component close to the tilt joint and related to the shaft for tilting. In most tilting umbrellas, such as those disclosed in US Pat. No. 3,850,186 (Weber et al.), US Pat. No. 4,697,606 (Ma) or US Pat. to tilt. [0003] S N Small also proposes this type of device in US-A-3182673 and other applications, where the tilting takes place over the slip ring. Although these devices have been around for a relatively long...
