1. Field of the Invention
The present invention relates generally to collapsible umbrellas securable in an upwardly arrayed and extending fashion. More specifically, the present invention relates to an expandable device utilized in such as a sports umbrella, as well as an expandable Christmas tree.
2. Description of the Prior Art
Folding umbrellas are well known in the art and which are designed to provide a degree of portable shading. The standard type of umbrella includes a main shaft having a top end and an opposite and curved handle end. A collar is slidably engaged along the substantial length of the shaft from between the handle end and a position proximate the top end. A plurality of elongate and arcuate skeletal portions are provided which make up the frame of the umbrella fabric covering portion and which extend in radially outward fashion from locations proximate the top end. A like plurality of ribbed portions extend in proximity to the axially slidable collar and interconnect at intermediate axial locations to each of the associated skeletal portions. A spring-loaded catch or locking tab of some form is typically provided at an upper end location of the main extending shaft and, upon coming into contact with the slidable annular collar, locks the collar in place at its elevated location and so that the pluralities of fabric supporting arcuate skeletal portions and interengaged and outwardly extending rib portions are locked in place.
U.S. Pat. No. 6,401,736, issued to Jerry, discloses an umbrella device incorporating an engaging mechanism for securing the umbrella to a fixed location. The device includes an elongated shaft having a top end and a bottom end which is capable of being extended across an overall axial length. A fabric covering portion is supported by an outwardly actuable frame secured to the shaft, the frame including a plurality of elongate and arcuate ribs to which is secured the fabric covering portion. An annular collar is mounted about the elongated shaft in axially extending fashion. An additional plurality of supporting ribs extend from the collar, each of the supporting ribs engaging an associated fabric securing rib so that, upon a selected upwardly axial extension of the collar, the frame is engaged in the outwardly actuated manner. A substantially “C” shaped clamp is secured in axially slidable fashion along the extended axial length of the shaft, the clamp affixing the umbrella device to a substantially horizontally extending ledge support.
U.S. Design Pat. No. 406,077 teaches a pop-up foldaway Christmas tree supported upon a rectangular base platform and including a plurality of expansible sections pivotally interconnected at a top end of an upwardly extending base stem, as well as translatable connectible through cross members along a lower and vertically translatable collar. Another example of a coupling device for a collapsible sunshade umbrella is illustrated in U.S. Pat. No. 5,878,762, issued to Huang, and which includes a coupling base with a supporting column having a first end portion and a second end portion containing an insertion socket therein. Two juxtaposed extension ears each extend outwardly from the outer wall of the supporting column and is formed with a plurality of locking ribs. A pivot base includes a rotary block rotatably mounted between the two extension ears and including two sides, each containing a plurality of locking indents each receiving one of the plurality of locking ribs of each of the two extension ears, and a supporting tube fixedly mounted on the rotary block.
U.S. Design Pat. No. 413,429, issued to Carson, illustrates a clamp for supporting an umbrella and which appears to show a substantially “C” shaped frame having an axially extending and internally hollowed cylindrical sleeve integrally formed therewith. The presumption from the title of the invention is that the shaft or main body of the umbrella is insertingly engaged through the sleeve and the thumbscrew illustrated is employed to secure the clamp at a selected axial location along the umbrella sleeve. The clamp of Carson further illustrates a main and exteriorly threaded bolt which is interengageably and threadably secured through an appropriately sized aperture in the lower arm of the “C” shaped member. A pincer support attached to an extending end of the bolt includes an arcuately configured upper surface and, upon rotating the bolt to translating in one of two directions, is positioned in opposing fashion to a corresponding and arcuately configured inner facing surface of the upper arm of the “C” shaped member.
U.S. Pat. No. 5,836,327, issued to Davis, teaches an umbrella holder for grasping the lower and curved handle end of a conventional umbrella and which includes a clamp mechanism, a forward/rearward angular adjustment mechanism, a length adjustment mechanism, and an umbrella shaft and handle securing mechanism. The device of Davis is a separate device manufactured for use with the conventionally constructed umbrella.
U.S. Pat. No. 3,345,786, issued to Buzzella, teaches a vented metal umbrella of the type produced in knock-down or kit form for compact storage and shipment prior to assembly at the site of use. A generally vertical support structure includes a lower support tube, an upper support tube telescopingly received within the upper end of the lower tube. A knuckle member is affixed to an upper end of the upper support tube. A collar is secured to a location of the upper tube, at a position below the knuckle member, and includes a set screw extending through an opening in the tube for adjustably securing the upper support tube. An adjustable knuckle arm is also provided and secures in rotatably adjustable and end-to-end fashion to the knuckle member. An umbrella covering cone is secured to a circular flange extending from an upper end of the adjustable knuckle arm and by means of an intermediate mounted and umbrella support disc.
SUMMARY OF THE PRESENT INVENTIONAn extensible device is disclosed, and such as is for use with an umbrella engaging mechanism or, as will be described in an alternate embodiment, a decorative supported tree. The present invention is an improvement over the prior art in that it provides an improved construction for quickly being supported upon a ground engaging location.
In a first variant, an elongated and lengthwise shaft includes an outer elongated tubular portion within which is supported in axially repositionable fashion an inner translatable portion. A repositionable clamp device is supported at an upper end of the device, such as for releasably securing a conventional umbrella stem.
A rotatable foot support is arranged at a lower end and facilitates driving the shaft into a ground location. The foot support can either be internally or externally supported relative to the inner or outer elongated portions.
In one variant, a rubber dampening insert is secured to a hollowed end of the outer tubular portion and receives a cord extending therethrough. An interior end of the cord secures to a translatable and noise generating anchor, supported upon the end of the inner translatable portion. In this fashion, a desired audible noise can be generated upon retraction (upward inner displacement) of the inner translatable portion of the shaft relative to the fixed outer tubular portion.
In another variant, the extensible device functions as a base support for a decorative tree. A plurality of elongated ribs are outwardly extensibly mounted to the outer tubular member, at least pivotally at their upper ends, and each further including a faux pine branch design. The ribs may also be translatably supported at additional intermediate locations to the fixed outer tubular portion and it is also envisioned that additional features such as a decorative canopy and/or ornaments can be provided in interacting fashion with the faux multiple rib design.
