DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

(21) Referring now to the figures, a conventional garden rake work implement X is shown in FIGS. 2a, 2b, 3a and 3b.

(22) FIGS. 2a and 3a show where the present invention is folded to allow the work implement to be operational. In FIGS. 2b and 3b, the work implement X is standing uprightly and stably with the aid of the present invention.

(23) The conventional garden rake work implement X includes a long handle with a cross section. The cross section has an upper portion handle 1a and a lower portion handle 1b. The support fixture is securely attached to the lower portion handle 1b of the rake's handle.

(24) The support fixture assembly includes a mounting bracket generally indicated as A, B or C, and a standing leg generally indicated as D. Specifically, the clamp type mounting bracket is indicated as A in FIGS. 1a, 2a, 2b, 3a, 3b, 6, 7 and 8. The snap type mounting bracket is indicated as B in FIGS. 1b and 9, and the screw type mounting bracket is indicated as C in FIGS. 1c, 10a and 10b.

(25) Further in FIGS. 2a and 3a, the standing leg D is operatively adjusted upwards to rest on the work implement X when the work implement X is operational. However, some users may prefer to operate the work implement X when the standing leg D is in the downward position.

(26) In FIGS. 3a and 3b, the standing leg D includes top ends D1 and a bottom section D2. The top ends D1 are hingedly attached to mounting bracket A. The bottom section D2 rests on a floor, ground or support surface 2 at contact points generally indicated as 2a in FIG. 3b.

(27) Further, in FIG. 3a, the standing leg D is operatively adjusted upwards. In this upward position, the bottom section D2 of the standing leg D tightly rests on the handle 1b of the work implement X and makes the work implement X ready for use.

(28) In FIG. 3b, the standing leg D is operatively adjusted downwards. In the downward position, the bottom section D2 rests on the floor, ground or support surface 2 and aids the work implement X to stand uprightly and stably.

(29) Further in FIG. 3b, the work implement X is engaged with the floor, ground or support surface 2 at contacts points generally indicated as 2b. The center of gravity 1e of the work implement X lies vertically within the point 1f where the standing leg D is engaged with the floor, ground or support surface 2a, and the point where the work implement X is engaged with the floor, ground or support surface 2b.

(30) The upward and downward operative adjustments of the standing leg D are achieved when the user applies equal, opposite and simultaneous forces F1 at points generally indicated as D3, then, operatively adjusts the standing leg D accordingly, and finally, releases the forces F1.

(31) In the present invention, the standing leg D is made using stainless hard drawn spring steel rod. Other materials that exhibit the same physical properties can be used to achieve the same result. The standing leg D is of spring steel material in that when two equal and simultaneous forces F1 pointing at each other are applied at points indicated as D3, and then released, the standing leg D will return to its original free standing shape as in FIG. 4a.

(32) Further, FIG. 4a shows the standing leg D before it is hingedly engaged with the mounting bracket A, B or C and FIG. 4b show the standing leg D after it is hingedly engaged with the mounting bracket A, B or C.

(33) Referring to FIGS. 4a, and 4b, the standing leg D is a long rod configured into multiple symmetrical shapes along its length. The FIGS. reveal the long rod deliberately sharped to achieve a plurality of performance characteristics, such that: (a) When forces F1 are applied at points indicated as D3, standing leg D is compressed horizontally; (b) Top ends D1 form a hinge with mounting bracket A, B or C when top ends D1 are inserted into mounting bracket A, B or C; (c) Standing leg D produces enough forces F2 used to clamp onto both sides of the mounting bracket A, B or C; (d) The standing leg D is configured to have a bottom section D2 which increases the stability of the work implement X during engagement with the floor, ground or support surface 2.

(34) Mounting brackets A, B or C has through holes 3 as shown in FIGS. 6 and 7. In order to prevent the standing leg D from disengagement from the through holes 3 during the application of forces F1, the top ends D1 are constructed according to FIG. 5a, 5b, 5c or 5d. FIG. 5a shows how the top ends D1 of the standing leg D is constructed for cotter pin retention. FIG. 5b shows how the top ends D1 of the standing leg D is constructed for retaining pin retention. FIG. 5c shows how the top ends D1 of the standing leg D is constructed for coining compression retention. FIG. 5d shows how the top ends D1 of the standing leg D is constructed for e-dips retention.

(35) While the top ends D1 are constructed as shown in FIG. 5a, 5b, 5c or 5d, those having ordinary skill in the arts will appreciate that other methods of construction are possible to prevent the disengagement of top ends D1 from through holes 3.

(36) FIGS. 6,7 and 8 reveal some essential features of the clamp type mounting bracket A. Cavity 7B is configured to accept different types and sizes of implement handles 1b. Vertical grooves 10B are carved along the surface of the cavity 7B to allow the mounting bracket A to grip more tightly as fastener means clamp E is fastened.

(37) Another important feature of the support fixture is depicted on top slot wall 4, shown in FIG. 6. Top slot wall 4 is configured such that when there is excessive force on mounting bracket A, B or C, enough to bend or damage standing leg D, the standing leg D will disengage from top slot wall 4. The disengagement is a safety measure that prevents the standing leg D from bending or damaging.

(38) Side sectional view shown in FIG. 7 is used to further illustrate additional advantages of the present invention. Mounting bracket A, B or C has a pair of bottom slot 15 and a pair of top slot 14. Both bottom slot 15 and top slot 14 coincide and are perpendicular with through holes 3. On one side of the mounting bracket A, B or C, one bottom slot 15 and one top slot 14 form a continuous slot. On the other side of the mounting bracket A, B or C, one bottom slot 15 and one top slot 14 form another continuous slot. Standing led D is guided by top slot 14 when standing leg D is folded as in the upwards position. Standing leg D is guided by bottom slot 15 when standing leg D is unfolded as in the downwards position.

(39) Top slots 14 are constructed to maintain an acute angle 81 relative to vertical sides 9. The acute angle 91 enables the standing leg D to rest tightly on the handle 16 of the work implement X when the implement X is operational.

(40) Bottom slots 15 are constructed to maintain an acute angle 63 relative to vertical sides 9. The acute angle 82 enables the standing leg D to maintain a stable stance with the work implement X.

(41) In FIG. 8, the fastener means such as clamp E is shown and it is used to securedly attach the clamp type mounting bracket A onto the handle 16. Clamp E is inserted into one end of a rectangular clamp slot generally indicated as 8B. Upon emerging from the other side of the slot 8B, the clamp E wraps around handle 1b. By adjustably tightening clamp screw E1, the clamp type mounting bracket A firmly grips handle 16.

(42) FIG. 9 illustrates the snap type mounting brackets B. The snap type mounting bracket B has cavity 5A as fastener means to receive the lower portion or handle 16 of the work implement X. Size and shape of the cavity 5A are constructed to easily accept and tightly grip the handle 16.

(43) While the work implement X is shown and described to be attached with support fixture having the clamp type A or snap type B mounting brackets, those having ordinary skill in the art will appreciate that attaching the support fixture can be achieved using other methods. Thus, it will be understood that the present invention is not limited to attachment using only the clamp type mounting bracket A or the snap type mounting bracket B.

(44) As an example, in FIG. 10a, another embodiment of the support fixture is shown using conventional screws H as fastener means for mounting the screw type mounting bracket C. The screw type mounting bracket C is adequately designed for work implements with frames 1c, such as leaf rakes Y. FIG. 10a also shows a leaf rake Y with tall flexible prongs 1d extending from its frame 1c. The screw type mounting bracket C is secured at the center of the frame 1c along its vertical axis as indicated by frame holes 11C. A plurality of mounting holes 13C is located at the center of the screw type mounting bracket C. Threaded insert 12C forms an integral part of the mounting holes 13C. The mounting screws H are inserted in frame holes 11C from the front side of the leaf rake Y. The mounting screws H engage onto the threaded inserts 12C and are operatively tightened. Engagement of the mounting screws H and operatively tightening same firmly secures the screw type mounting bracket C on the frame 1c of the leaf rake Y.

(45) While the support fixture assembly illustrated thus far are shown in connection with conventional rakes, those having ordinary skill in the art will appreciate that the support fixture may be employed to other tools and items, such as long handled paint rollers, shovels, squeegees, long handled trowels, vacuum cleaner wands, walking sticks, long handled shears and others. Thus, it will be understood that the present invention is not limited for use solely in connection with tool implements with long handles, but for use in all applications where stable upright standing are required.

(46) Another example where the screw type mounting bracket C can be used is shown in FIG. 10b. Mounting screws H is inserted into mounting holes 10C on frame 1g of a flat item such as a display board Z. Using a conventional screw driver (not shown), the mounting screws H are operatively fastened into threaded insert 12C. The operation secures the screw type mounting bracket C onto the board Z.

(47) Mounting bracket C can also be secured to frame 1c or 1g using conventional screws H and conventional nuts (not shown).

(48) While one mounting bracket A, B or C has been shown in this disclosure to aid the standing of one item such as X, Y or Z, anyone skilled in the arts will appreciate that a plurality of support fixtures can be used to stand wide items.
