Portable wind resistant target and sign stand

Abstract

A portable wind resistant target and sign stand, that is lightweight, wind resistant and can be stored in a relatively small container approximately two feet tall and five inches in diameter. The stand is made of rigid pipes that can be rapidly and easily assembled and disassembled without tools, The stand can accommodate target or sign panels of varying height or width, as the backdrops can be secured at any position along the vertically adjustable, horizontally disposed, rigid crossbars by a plurality of spring clips or, alternatively, a plurality of magnets if said crossbar is made of ferrous metal. Wind resistance is enhanced by a novel three-way-tee fitting assembly developed for this application.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure, or manner.

(14) Referring now to FIG. 1 we see a perspective view of the embodiment 100. An H-shaped base 12, as shown in FIG. 2, is made of two or more left 4 and two or more right 6 pipe members attached via three-way-tee fitting assembly 22, 24, to the central pipe member 16. Second three-way-tee connector assembly 20, 26, as seen in FIG. 4, engage the central tubular member 16 so that the left 4 and right 6 vertical tubular supports are positioned ninety degrees from the base. Alternately, the three-way-tee connector assembly can be replaced by standard individual three-way-tee fittings that the user can elect to rotate to an alternate angle if so desired. Vertical support tubes 4, 6 each are formed by at least two equal lengths of tube that are connected at location 30 by standard connector members not shown. The support frame 100 is typically approximately two feet wide and four feet tall. Since the vertical tubes 4, 6 can be detached at location 30, and the base cross base support pipes 14, 18 can be detached from central pipe 16, the entire support assembly 100 can be taken apart and stored in a pouch that is approximately two feet tall and five inches in diameter. The target 2 shown in FIG. 1 is held to horizontally disposed, rigid crossbars 32, 34 via spring biased clips 10. The horizontally disposed, rigid crossbars 32, 34 are fastened to the vertical support tubes 4, 6 via U shaped retaining members 8. The U shaped retaining members are attached through apertures in the horizontally disposed, rigid crossbars 32, 34 and slidably held in place by wing nuts 38 shown in FIG. 5.

(15) FIG. 2 is a perspective view of a sign panel 28 being held to the horizontally disposed, rigid crossbars 32, 34 via spring biased clips 10.

(16) FIG. 3 is a partial perspective rear view of the upper portion of the stand 100 clearly showing horizontally disposed, rigid crossbars 32, 34 attached by U shaped retaining members 8 via wing nuts 38. The user can without tools rapidly adjust the height of the horizontally disposed, rigid crossbars 32, 34 by loosening the wing nuts 38 and sliding the U shaped members 8 up or down, uniquely allowing for target or sign panels of different heights. Additionally, the user can slide spring biased clips 10 inward or outward, along the horizontally disposed, rigid crossbars 32, 34, uniquely allowing for target or sign panels of different widths.

(17) FIG. 4 is an exploded view of the portable target and sign stand showing base support members 14, 18 removed from central pipe 16. Second tee connectors 20, 22 can be slid off of central pipe 16 for compact storage of the embodiment 100.

(18) FIG. 5 is a partial exploded view showing horizontally disposed, rigid crossbar 32 about to be attached to left 4 and right 6 vertical tubes via U shaped retaining members 8 and wing nuts 38.

(19) FIG. 6 is a partial perspective view showing spring biased clip 10 about to be attached to sign panel 28 and horizontally disposed, rigid crossbar 32.

(20) FIG. 7 is a perspective view of the embodiment 100 with the target panel 2 being held to ferrous metal crossbars 32, 34 by magnets 42.

(21) FIG. 8 is a partial exploded perspective view of the embodiment with magnets 42 about to be installed on target panel 2 where their magnetic force penetrates target panel 2 and attaches magnetically to ferrous metal crossbar 32.

(22) The entire assembly 100 can be assembled and disassembled by a person without the need of standard tools. The entire assembly, excluding the horizontally disposed, rigid crossbars, is preferably made of light weight PVC or other plastic material making it easy to transport.

(23) FIG. 9 is an exploded view of the embodiment 100 with the metal cross bars 332, 336 having equally spaced holes 334, 338 which allow the attachment of a backdrop of thin plastic material 340 such as the Dupont sheet Tyvek or of a ferromagnetic sheet, the thickness of which is selected to be penetrable by a projectile discharged at the target from a weapon. The backdrop 340 is perforated with a plurality of slots 342 allow air to pass through the backdrop 340 on windy days thereby reducing the change of having the stand 100 blow over in the wind. Two sets of three screws 346, 350 and wing nuts 350, 348 attach the backdrop to the cross bars 332, 336. A standard paper target 344 has adhesive backing to attach the target 344 to plastic backdrop 340.

(24) FIG. 10 is a perspective view of the embodiment 100 showing the plastic backdrop 340 attached to the cross bars 332, 336 and the target 344 adhered in place on the backdrop 340.

(25) FIG. 11 shows a perspective view of the novel three-way-tee fitting assembly comprised of two modified three-way-tee fittings and a short tube frictionally inserted into the short arms of both three-way-tee fittings.

(26) One of the modified three-way-tee fitting's short arm includes two slots, disposed opposite of each other, while the other three-way-tee fitting's short arm includes two notches also disposed opposite of each other. The slots and notches are sized to mate frictionally.

(27) The short tube, frictionally inserted into the two modified three-way-tee fittings is not visible when the fittings are joined. Additionally, the short tube is electro welded to the fittings.

(28) The herein described novel three-way-tee fitting assembly was developed to make the stand wind resistant, that is, resistant to being tipped over in light to moderate winds.
