The blade also has a third position at substantially a right angle between the handle axis and the blade axis. A pair of braces are attached to the blade. A plurality of holes are provided at the upper end of the pair of braces, wherein one hole of the first cross brace is aligned with one hole of the second cross brace for establishing each of the first, second, and third positions of the blade.

## Background
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates generally to the field of snow shovels and in particular to a new and useful snow shovel having a pair of braces which reinforce an angled snow shovel blade.
Several patents teach angle adjustable blades for shovels. One such patent teaches a shovel blade that is adjustable via braces. U.S. Pat. No. 2,896,993, discloses a pair of braces which are separately attached to opposite sides of a shovel blade at their lower end and converge together at their upper end to be connected to a handle via a pivot pin. However, the braces are not adjustable with respect to each other to change the angle of the blade. Rather, the angle of the blade is changed based on pivoting caused by rotation or twisting of the handle.
U.S. Pat. No. 5,440,828 to Simpson discloses a shovel comprising a blade having a rear bracket pivotally connected to a handle via a handle pivot pin or bolt so that the handle can be moved to an obliquely angled position with respect to the blade. A frame having an arched transverse member and a restraining bar lying horizontally between opposite substantially vertical sides of the transverse member define a channel for receiving the handle. The handle is pivotable via the pivot pin or bolt, and therefore slidable inside the channel over a range of angular positions oblique to each side of the shovel limited by the length of the channel.
U.S. Pat. No. 2,463,150 discloses a shovel having a blade with an H-frame attached to its rear, and a bracket journalled upon the legs of the H-frame. A handle contains a dial at its lower end attached to the bracket via a screw, wherein the dial has holes arranged in an outer circle of the dial. The handle is titled laterally at an angle with respect to the bracket, and a stud fixed upon the bracket, is inserted through the center dial hole to maintain the angle of the handle with respect to the bracket. The handle can also be articulated away from the blade via a pivotal rod and attached to a clamping lever.
U.S. Pat. No. 813,983 and U.S. Pat. No. 5,829,808 disclose a shovel with the shovel blade pivotally attached to the handle so that the blade can tilt to the left or right. The blade is connected to the handle by two bolts or screws arranged vertically. The upper bolt is mounted through an arcuate slot in the shovel blade, while the lower bolt is the pivot point. In a second embodiment in U.S. Pat. No. 813,983, the blade is reversed so that the lower bolt is mounted through an arcuate slot and the upper bolt is the pivot point. Thus, the edges of the blade can be tilted off horizontal, theoretically to cause snow to move to one side when the shovel is used as a plow. However, it appears that if the bottom edge is not flat, some snow would remain behind when using the shovel in this manner.
U.S. Pat. No. 1,196,206 discloses a scoop or scraper which may be adjusted laterally with respect to a handle via a pivoting connection comprising an eye hook having a shank riveted to the scoop which passes through an eye in a connecting member of the handle. A wingnut restrains a bail contained in a notch and connected to the rear face of the scoop, which can be loosened to allow the bail to slip through the notch as the scoop is adjusted laterally.
The following patents also disclose laterally adjustable shovel blades, and are listed for general reference: U.S. Pat. Nos. 2,803,071, 2,919,153, 4,538,847, 4,559,726, 5,984,393, 6,457,757, 6,675,507, and 6,948,268.
Also, there are patents which disclose assembly of handles by pins connecting one handle portion to another handle portion. U.S. Pat. No. 5,048,883 discloses an adjustable rail of a handle arrangement comprising a lower tubular portion and an upper tubular portion slidable within the lower tubular portion, wherein both the upper and lower tubular portions have holes which can be aligned so that the upper tubular portion can be fixed with respect to the lower tubular portion a particular position by a screw fastener which is inserted through aligned holes of the respective tubular portions.
There is a need in the art for reinforcement for laterally adjustable blades of shovels. All of the prior art patents teach simple and delicate pivoting connections via pins, eye hooks, etc, without any type of reinforcement for preventing wobbling of the blade or the tendency for the blade to turn when snow is shoveled. The prior art fails to teach reinforcement for laterally adjustable blades which can also be used as support or leverage during shoveling.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a snow shovel with a reinforced angle adjusted blade for preventing the blade from turning or wobbling when snow is shoveled.
It is a further object of the present invention to provide reinforcement for an angle adjustable blade which can also be used for support or leverage during shoveling.
Accordingly, a shovel is provided which includes a handle assembly being pivotally connected to a blade for pivoting between a first position at a first acute angle between the horizontal blade axis and the substantially vertical handle axis and a second position at a second acute angle between the horizontal blade axis and the substantially vertical handle axis. The blade also has a third position at substantially a right angle between the substantially vertical handle axis and the horizontal blade axis.
The shovel includes a pivoting means for pivoting the handle assembly with respect to the blade. The pivoting means includes either a bracket that pivots with respect to the blade or a bracket that is permanently attached to the blade but is also pivotally connected to the lower handle assembly. If the pivoting means is a bracket that pivots with respect to the blade, the area of pivotal connection is in the center of the blade. If the pivoting means is a bracket that is permanently attached to the blade but is pivotally connected to the lower handle assembly, the area of pivotal connection is between an upper bracket region and the lower handle assembly.
A pair of braces having a hole at their lower end are attached via fasteners to holes on opposites sides of a center vertical axis of the blade. A plurality of holes are provided along a vertical axis at the upper end of the pair of braces, wherein one hole of the first cross brace is aligned with one hole of the second cross brace for establishing each of the first, second, and third positions of the blade. The holes at the upper end of the cross braces are aligned with and connected to a stem of the handle assembly at a bracing location. The stem is attached at its lower end to the bracket and its upper end to a handle.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which a preferred embodiment of the invention is illustrated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, in which like reference numerals are used to refer to the same or similar elements, FIGS. 1A-1B show a manual shovel 10 for snow or ice removal and the like, comprising a blade 20 pivotally connected to a bracket 30 and also attached to a pair of cross braces 40. A handle assembly 50 is connected to the bracket 30.
The blade 20 is substantially arcuate and includes a front face and a rear face 22b, top and bottom ends 24a and 24b, and sides 26a and 26b. The blade 20 further includes a center horizontal axis B1 and a center vertical axis B2. The blade 20 includes one arcuate slot 28a and one hole 28b lying separately along the center vertical axis B2, wherein the arcuate slot 28a is positioned above the hole 28b. The arcuate slot 28a curves inwardly toward the hole 28b, or in other words, the ends of the slot 28a are curved down. It is not essential that the arcuate slot 28a be positioned above the hole 28b. As shown in FIG. 2 for example, the arcuate slot 28a may be positioned below the hole 28b as well, but the arcuate slot 28a must be arranged so that it curves inwardly toward the hole 28b , or in this case, the ends of the slot 28a are curved up. The blade 20 further includes holes 29a and 29b on opposite sides of the center vertical axis B2 for attachment to the cross braces 40 as will be described in further detail below. The body of the blade 20 between the ends 24a and 24b is substantially arcuate or concave. However, the arcuate shape of the blade 20 changes into a long leading planar edge near the bottom end 24b.
The bracket 30 has a top portion 32a, a bottom portion 32b, and a center pivoting point 34 between the top and bottom portions 32a and 32b. The bottom portion 32b is flattened while the top portion 32a is cylindrical. The flat bottom portion 32b contains at least two holes 38a and 38b (see FIGS. 3A, 3B) lying along a center vertical axis of the bracket 30, which are lined up with the arcuate slot 28a and hole 28b in the blade 20 for attachment of the bracket 30 to the blade 20 when the front face of the bracket bottom end is placed against the rear face of the blade 20.
For attachment of the bracket 30 to the blade 20, a pair of fasteners such as bolts 21a and 21b are inserted into the arcuate slot 28a and hole 28b from the front of the blade 20. The bolt 21a for the arcuate slot 28a has a head which is larger than the width of the arcuate slot 28a so that the bolt 21a cannot slip through the slot 28a, while the length of the bolt extends through the blade from the front side to the rear side of the blade, and through a corresponding hole 38a in the bracket 30. The head of the bolt rests against the front face of the blade. A nut is screwed onto the protruding length of the bolt from the rear of the bracket 30 and screwed against the rear of the bracket 30. The bracket 30 is thus freely pivotable in left and right directions along the arcuate slot 28a, but cannot be pivoted in any other direction due to the attachment via the bolts. The bracket 30 is pivotable between a first position on one side of the arcuate slot 28a at a first acute angle C between the handle axis A on one side of vertical, and the horizontal blade axis B1 and a second position (not shown in FIG. 2) on the opposite side of the arcuate slot 28a at a second acute angle D between the bracket axis A and the horizontal blade axis B1. The bracket also has a third position in the center of the arcuate slot 28a at a substantially right angle between the substantially vertical handle axis A and the horizontal blade axis B1.
A lock washer may be arranged between the rear face of the bracket bottom end and the nut screwed on the bolt length against the rear face of the bracket bottom. The lock washer, such as for example, a star-type lock washer helps to prevent the loosening of the nut.
The pair of cross braces 40 each have a top portion 42a and a bottom portion 42b. The bottom portions 42b each have a hole 46 (see FIGS. 3A, 3B) which are lined up with the holes 29a and 29b on opposites sides of the vertical center axis B2. The pair of cross braces also have at least three holes 48a, 48b, and 48c at the top portion.
For attachment of the cross braces 40 to the blade 20, a pair of fasteners such as bolts are inserted into the holes 29a and 29b from the front of the blade 20. The head of the bolts rest against the front face of the blade 20. A nut is screwed onto the protruding length of the bolt from the rear of the cross braces 40 and screwed against the rear of the cross braces 40. A lock washer may be arranged between the rear face of the cross brace bottom end and the nut screwed on the bolt length against the rear face of the cross brace bottom. The lock washer, such as for example, a star-type lock washer helps to prevent the loosening of the nut.
A handle assembly 50 includes a cylindrical stem 52 having a top portion 52a and a bottom portion 52b. The bottom portion 52b is connected to the cylindrical top portion 32a of the bracket 30 and the top portion 52a is connected to a handle 60. The bottom portion 52b has a smaller diameter than the top portion 32a and is inserted into the top portion 32a. Both the bottom portion 52b and the top portion 32a have corresponding holes such that when the bottom portion 52b is inserted into the top portion 32a, and the holes are aligned, a fastening means 80 can be used to secure the portions 52b and 32a. The fastening means 80 includes screws, bolts and nuts, or even depressible buttons biased by a resilient means such as a spring.
For example, the stem 52 has depressible buttons on opposite sides of the stem at the bottom portion 52b. The buttons are pushed into the stem and against a resilient means such as spring. The bracket 30 contains holes on opposite sides at its top portion 32a. When the bottom portion 52b of the stem 52 is inserted into the top portion 32a with the bottom portion buttons depressed, and the buttons reach the holes, the buttons expand out through the holes from the biasing force of the spring, locking the bottom portion 52b of the stem into the bracket 30.
The cross braces 40 are attached to stem 52 at a bracing location as follows. Both the top portion 42a of the braces and the bottom portion 52b of the stem have holes, which can be aligned, so that a long stove bolt 70 can be inserted through the holes upon alignment, to connect each of the cross braces to the stem at the bracing location. More specifically, the bottom portion 52b of the stem has one hole 56 and each of the braces has at least three holes, a first top hole 48a, a second middle hole 48b, and a third bottom hole 48c, which are arranged along a center vertical axis of the cross braces. The cross braces are adjusted to converge their top ends at the hole 56, where at least one hole from each of the cross braces overlaps the hole 56. This adjustment is made by pivoting the cross braces about the hole 29a, 29b to which they are respectively attached.
If the bolt 21a for connection of the bracket to the arcuate slot 28a is lined up in the center of the arcuate slot 28a, then the cross braces are adjusted to converge at the middle hole 48b of each of the cross braces. Once the middle holes 48b of the cross braces are aligned with the hole 56 in the stem, a long stove bolt 70 is inserted into the stem hole 56 and through the aligned cross brace middle holes 48b. A nut, wingnut, or the like screws onto the threaded opposite end of the stove bolt and rests against the cross braces. If the bolt 21a is moved to the leftmost end of the arcuate slot 28a, then the left cross brace is only adjusted so that the bottom hole 48c is aligned with the hole 56 of the stem and the right cross brace is adjusted so that the top hole 48a converges with the bottom hole 48c of the left cross brace and the hole 56. The stove bolt 70 and a nut or wingnut connect the hole 56 to the bottom hole 48c of the left cross brace and the top hole 48a of the right cross brace. In likewise fashion, the left and right cross braces may be adjusted if the bolt 21a is moved to the rightmost end of the slot 28a, so that the hole 56 is aligned with and connected to the top hole 48a of the left cross brace and the bottom hole 48c of the right cross brace.
The end of the top portion 52a of the stem 52 has external threads and a cylindrical base 62 of the handle 60 contains internal threads which cooperate with the stem external threads to screw the handle 60 onto the stem 52.
In a second embodiment shown in FIGS. 2-3, a screw knob 73 may be used in place of the stove bolt and nut combination to attach one of the holes 48a, 48b, 48c of each of the cross braces to the hole 56 of the stem.
In a third embodiment shown in FIG. 4, the bracket 30 is pivotally connected to the blade 20 only when the holes 38b and 28b of the bracket 30 and blade 20 respectively are aligned and fastened by a bolt and nut or other similar fastening means. There is no arcuate slot 28a. 
In a fourth embodiment shown in FIGS. 2, 3A, 3B, and 5, two stems 102 and 104 are provided, wherein the bottom stem 102 has a bottom portion 102b and a top portion 102a and the top stem 104 has a bottom portion 104b and a top portion 104a. The top portion 102a attaches to the bottom portion 104b. The bottom stem 102 attaches to the top portion 32a of the bracket 30 via the bottom portion 102b. The top stem 104 attaches to the base 62 of the handle 60 via the top portion 102a. Attachment can be made via any of the means of attachment described above such as cooperation of depressible buttons with holes or bolts with nuts.
In a fifth embodiment shown in FIG. 3A, the arcuate slot 28a is replaced with an arcuately aligned set of holes, generally designated 120. A connector such as a bolt and nut connects the bracket 30 to the blade 20 via aligned holes 28b and 38b. A bolt, screw or other male fastening means can be inserted through any one of the arcuately aligned set of holes 120 to fasten the blade 20 to the bracket 30. A screw knob may be used for fastening as well. The bracket 30 contains a hole 38a. The bracket 30 is pivoted to a desired angle based on a chosen hole in the arcuate set of holes so that the chosen hole is aligned with the bracket hole. Then the bolt is inserted through the chosen hole of the arcuate set of holes and the hole 38a, thereby locking bracket 30, and attached stem 52 (or stems 102 and 104) and handle 60, at the desired angle with respect to the blade 20. In FIG. 3B, it is shown that the arcuately aligned set of holes 120 may also be provided in the bracket 30.
As also shown in FIGS. 3A-3B, the snow or ice shovel of the present invention can be provided as a kit and conveniently arranged in a small box. The kit includes the blade 20 and a bracket 30 attached to the rear of the blade 20, two cross braces 40, first and second stems 102, 104 which are interchangeable (or simply one stem 52), and a handle 60. The kit can be easily assembled and disassembled for portability and storage.
In a sixth embodiment shown in FIG. 6, the handle assembly 50 and bracket 30 of the former embodiments are formed as one handle piece 90.
In a seventh embodiment shown in FIG. 7, the handle 60 is attached to the top portion 52a of the stem via a bolt and nut or other fastening means 80. The base 62 of the handle 60 has a hole (not shown) and the top portion 52a of the stem has a hole (not shown). The base 62 is cylindrical and has a diameter that is larger than the diameter of the top portion 52a of the stem. Thus, the stem 52 is inserted into the base 62 of the handle 60 and their respective holes are aligned so that a bolt is inserted through the holes to connect the stem 52 to the base 62 of the handle 60.
In a eighth embodiment shown in FIG. 8, the arcuate slot in the blade 20 is eliminated and an arcuate slot 128a is provided on a bracket 130 that is fixed to the blade. Thus, the bracket 130 is not pivotally attached to the blade 20. However, the handle assembly 50 is still pivotable with respect to the blade 20.
The bracket 130 is fixed to the blade 20 as follows. The bracket 130 comprises a bottom portion 132b and a top portion 132a. The bottom portion 132b is flat or slightly curved to follow the shape of the blade, and includes holes which are aligned with holes in the blade 20 so that bolts and nuts or other fasteners can be used to affix the bottom portion 132b of the bracket to the blade 20.
Pivoting connection of the handle assembly 50 with respect to the blade 20 is provided in the following manner. The top portion 132a of the bracket 130 contains an arcuate slot 128a above or below a hole 128b in accordance with the same configurations described for arcuate slot 28a and hole 28b. The bottom of handle assembly 50, or a second bracket connected to the bottom of the handle assembly 50, has holes for alignment with the arcuate slot 128a and the hole 128b respectively. Bolt 160, such as stove bolts, are passed through each set of aligned holes and nuts 162 are fastened to the bolts. Therefore, the handle assembly is pivotally connected to the bracket 130 for the center, left or right positions of the handle with respect to the blade.
In a ninth embodiment shown in FIG. 9, the arcuate slot 128a of FIG. 8 is replaced with an arcuately aligned set of holes, generally designated 170. The handle assembly is pivoted to a desired angle based on a chosen hole in the arcuate set of holes so that the chosen hole is aligned with the handle assembly hole. Then the bolt is inserted through the chosen hole of the arcuately aligned set of holes and the hole 128b, thereby locking bracket 130, and attached stem 52 (or stems 102 and 104) and handle 60, at the desired angle with respect to the blade 20. Screw knobs may be used instead of bolts and nuts.
In the embodiments of FIGS. 8 and 9, cross braces 40 can be provided between the hole 128b of the bracket 130 and the opposite sides of the blade to better brace the blade against undesired rotation with respect to the handle assembly.
While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
