摘要 | The present invention may be used for debris collection and vegetation removal. An interior shaft may be slidably disposed in an exterior tubular shaft. The interior shaft may protrude out of a lower end of the exterior tubular shaft and a prong assembly may have a plurality of prongs oriented in a subtending direction may be attached at a lower end of the interior shaft. A tubular housing may be attached at the lower end of the exterior tubular shaft in a position to receive the plurality of prongs when the interior shaft may be pulled upwardly relative to the exterior tubular shaft. | ||||||

说明书全文 | This invention relates to apparatus for ground debris collection and vegetation removal. The new debris collection and vegetation removal apparatus may have a clamping mechanism that may include multiple gripping wires that may expand radially to encircle an object to be removed or gripped and then be closed to pick up the object. Various types of weed pullers or debris collection devices may be known and may include apparatus having a head with multiple blades or pick up arms that extend downward to pick up objects. These devices may have a hollow stem or pole to which the head is attached at a bottom and a handle with an operating lever may be attached at the top. The blades or cutting elements may be positioned relative to a weed and the handle operated to close the cutting blades or pick up arms to extract the plant. The blades or pick up arms are generally rigid members for operation of the device. Other devices may include hollow poles with sharpened prongs or blades at the bottom to dig into the ground around a weed as part of the removal operation. The blades or rigid prongs may be forced into the ground to dig and cut to pull up a weed. The present invention is directed to apparatus for debris collection and vegetation removal. An interior shaft may be slidably disposed in an exterior tubular shaft. The interior shaft may protrude out of a lower end of the exterior tubular shaft. A prong assembly may have a plurality of prongs oriented in a subtending direction and may be attached at a lower end of said interior shaft. A tubular housing may be attached at the lower end of the exterior tubular shaft in a position to receive the plurality of prongs when the interior shaft may be pulled upwardly relative to the exterior tubular shaft. These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims. The following detailed description represents the best currently contemplated modes for carrying out the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention. Referring to Referring to The interior shaft 14 have a stop ring 26 positioned on the shaft intermediate the lower end 22 and the upper end 28. The stop ring 26 may be positioned to restrain a spring 56 at a top end that may be slidably disposed on interior shaft 12. The spring 56 may be restrained at a bottom end by end fastener 54. The spring 56 may be biased to urge the interior shaft 14 upwardly relative to the exterior tubular shaft 12. The spring 56 may aid in pulling the prong assembly 20 upwardly and in retaining the prong assembly 20 in the tubular lousing 30. There may be a top closure 50 attached to upper end 28 that may have a ring for hanging the apparatus 10 for storage or for other use. The prong assembly 20 may have a circular prong fastener 18 to which the upper end of the prongs 24 or tines may be attached. The prong fastener 18 may be attached to the lower end 22 of the interior shaft 14. The prongs 24 may be constructed of a resilient wire or flat metal material, as for example, flexible steel as may be used for a leaf rake, or other composite material. The prongs 24 may be attached to the prong fastener 18 to be biased in an open or radial extended configuration when not confined as when pulled into tubular housing 30, as best viewed in Referring to While the invention has been particularly shown and described with respect to the illustrated embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention. |
