Description

BACKGROUND

Field of the Invention

The present invention relates generally to devices for forming concrete forms for pouring concrete slabs and the like. More particularly, it relates to a concrete form system that includes a plurality of brackets for supporting concrete forms.

Description of the Related Art

A typical prior art concrete form system uses wooden or metal stakes attached by nails to wooden boards (such as 2×4 or 2×6 planks) that are used as forms. A typical prior art concrete form system consists of a plurality of stakes inserted vertically into the ground and flush against a concrete form board so as to abut the concrete form board.

Once the concrete form board is properly positioned, nails are used to secure the stakes to the concrete form board. When using metal stakes, such stakes are provided with one or more transverse holes that extend through the stake so that nails can be inserted through the holes and driven into the concrete form board, thereby securing the concrete form board to the stakes.

Once the stakes are nailed to the concrete form board, it is difficult to vertically adjust the concrete form boards without removing the nails that secure the stakes to the concrete form boards. That is, in a typical prior art concrete form system, the nails that are holding the stakes to the concrete form board must be removed before the concrete form board can be raised or lowered relative to the stake. Also, depending on the vertical distance the concrete form board needs to be moved, the stakes may need to be removed from the ground, after which the stakes must be driven back into the ground at another location or height and reattached to the concrete form board with nails.

When using typical prior art metal stakes containing nail holes as previously discussed, it is often the case that such holes become filled with hardened concrete that makes subsequent use of such metal stakes difficult or impossible without first taking time to remove the hardened concrete. In addition, when using wood stakes, such stakes have a limited number of times they can have nails driven into them before they split. Also, the cost of nails, which can typically only used once, becomes expensive over time.

Thus, there exists a need in the art to provide a concrete form system that allows for easy vertical adjustment of the concrete form board once attached to a stake, that is reusable and does not require the use of nails to secure the concrete form board to the stake.

SUMMARY OF THE INVENTION

The present invention provides a concrete form system comprising a plurality of concrete form board brackets. The plurality of brackets includes brackets for securing the concrete form board to a conventional type metal or wood concrete form stake without the need of nails.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

In the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally in order to avoid obscuring the invention. In many cases, a description of the operation is sufficient to enable one to implement the various forms of the invention. It should be noted that there are many different and alternative configurations, devices and technologies to which the disclosed inventions may be applied. Thus, the full scope of the invention is not limited to the examples that are described below.

With reference now to the drawings in which like reference characters designate like or similar parts throughout the several views, FIG. 1 illustrates a first embodiment of a concrete form system, generally indicated at 10, in accordance with the principles of the present invention. The concrete form system 10 is comprised of a plurality of concrete form board retaining brackets 12, each configured to retain a concrete form board 14 to a respective stake 16. Each concrete form board retaining bracket 12 includes upper and lower stake retaining portions 18 and 20 that bias the stake 16 against the outer surface 22 of the concrete form board 14. The upper and lower stake retaining portions 18 and 20 define recesses 24 and 26, respectively, that engage an outer surface 28 of the stake 16 to hold the stake 16 relative to the bracket 12.

As will be described in more detail, once the stakes 16 are driven into the ground G and the form board 14 is secured to stakes 16 with brackets 12, the brackets 12 and thus the form board 14 can be vertically adjusted relative to the stake 16 without having to raise or lower the stake 16. This is accomplished by manually squeezing the end portions 18 and 20 of the bracket 12 toward each other until they are approximately parallel, which loosens the engagement of the bracket 12 with the stake 16 and allows the bracket 12 to be vertically adjusted by sliding it up or down relative to the stake 16. When the end portions 18 and 20 are released, the end portions 18 and 20 reengage with the stake to hold the bracket 12 relative to the stake 16.

A pair of substantially identical concrete form board corner brackets 30 and 32 each have a generally C-shaped configuration and are sized to slide over respective ends 34 and 36 of concrete form boards 14 and 38, respectively. The corner bracket 30 includes a pair of interlocking tabs 40 and 42 for engaging with corresponding interlocking tabs 44 and 46, respectively, of corner bracket 32. The engagement of the interlocking tabs 40 and 42 with interlocking tabs 44 and 46 connect the corner brackets 30 and 32 together in a hermaphroditic manner that allows the two corner brackets 30 and 32 to be pivotable relative to one another, thereby allowing the formation of an angle A between form board 14 and form board 38 to form a corner of concrete slab 50 having a desired angle A.

As further shown in FIGS. 2 and 3, the concrete form board bracket 12 defines a generally rectangular channel 51 between the upper and lower portions 18 and 20 and the back portion 52 that is vertically sized to receive a concrete form board 14. The height of the back portion 52 is sized to be slightly larger than a particularly sized height of a concrete form board 14 so that the concrete form board 14 can be fitted within the channel 51 of the bracket 12. The upper and lower portions 18 and 20 are outwardly arched or angled relative to the back portion 52. The back portion 52 is also arched when the bracket 12 is in its free state such that when portions 18 and 20 are flexed toward one another and become substantially parallel, back portion 52 becomes straight and perpendicular to portions 18 and 20. In addition, the bracket 12 is formed from spring steel or other resilient material, such as plastic, that will allow the curved end portions 18 and 20 to be flexed toward and become substantially parallel to one another during installation, but that will try to return to their pre-flexed state when released in order to bias the stake 16 against the form board 14 when released.

As best seen in FIG. 2, the upper and lower portions 18 and 20 of the bracket 12 each have a generally J-shaped configuration that define stake-retaining recesses 54 and 56, respectively. The stake-retaining recesses 54 and 56 have a generally J-shaped configuration configured to partially wrap around the stake 16 when engaged therewith. That is the stake-retaining recesses 54 and 56 include stake-retaining portions 55 and 57, respectively, that engage a portion of the stake 16 proximate the open sides 58 and 60, respectively, of the upper and lower portions 18 and 20. The stake-retaining portions 55 and 57 define a stake receiving recess 62 and 64, respectively. To accommodate a cylindrical stake 16 as shown, the stake receiving recesses 63 and 64 have an arcuate configuration to substantially match the radius of the stake 16.

As further illustrated in FIGS. 4, 5 and 6, the pair of concrete form board corner brackets 30 and 32 each has a generally rectangular and C-shaped configuration and is sized to slide over the respective ends 34 and 36 of concrete form boards 14 and 38, respectively. The pair of interlocking tabs 40 and 42 of corner bracket 30 are spaced from the proximal end 31 of the bracket 30 and define vertical slots 41 and 43, respectively, that vertically extend partially through the tabs 40 and 42, for engaging with corresponding slots 45 and 47 of interlocking tabs 44 and 46, respectively, of corner bracket 32. The engagement of the interlocking tabs 40 and 42 with interlocking tabs 44 and 46 connect the corner brackets 30 and 32 together, as shown in FIG. 5, in a manner that allows the two corner brackets 30 and 32 to be pivotable relative to one another, thereby allowing the formation of an angle A between form board 14 and form board 38 to form a corner of concrete slab 50 (see FIG. 1) having a desired angle A. As shown in FIGS. 4 and 5, the corner brackets 30 and 32 are slid onto the boards 14 and 38 to their relative stopping points 33 and 35 so that the body portions 30′ and 32′ extend beyond the ends 34 and 36 of the boards 14 and 38, respectively. This provides space for the tabs 40, 42, 44 and 46 to pivot relative to one another as the angle A is increased without the tabs 40, 42, 46 and 48 from being impeded by contacting the ends 34 and 36 of the boards 14 and 38, respectively.

Referring now to FIG. 7, the concrete form board retaining brackets 12 configured to retain a concrete form board to a respective stake as previously described is illustrated. Each concrete form board retaining bracket 12 includes upper and lower stake retaining portions 18 and 20 for biasing a stake against an outer surface of a concrete form board. The upper and lower stake retaining portions 18 and 20 define recesses 24 and 26 for engaging an outer surface of a stake to thereby hold the stake relative to the bracket 12. The brackets 12 are formed from spring steel or other semi-rigid, yet resilient materials, such as certain plastics. The bracket 12 shown in FIG. 7 is shown in a first resting position in that the upper and lower stake retaining portions 18 and 20 are upwardly arched relative to the back portion 52, which is also arched.

As shown in FIG. 8, the upper and lower stake retaining portions 18 and 20 can be flexed relative to one another and relative to the back portion 52 as indicated by the arrows. Flexing the upper and lower stake retaining portions 18 and 20 in this manner causes the perpendicular distances D1 and D2 (see FIG. 7) from the back portion 52 to the teeth of toothed edges 25 and 27 of the recesses 24 and 26, respectively, to increase and provide sufficient space for a stake 16 to pass between the concrete form board 22 and the edges 25 and 27. Releasing the upper and lower portions 18 and 20 allows the upper and lower portions 18 and 20 to spring back upward and downward, respectively, thereby grasping the stake 16 with the recesses 24 and 26 or the gripping teeth 25 and 27 (see FIG. 7) of round metal or wooden stakes, respectively.

As shown in FIG. 9, a second embodiment of a concrete form system, generally indicated at 100, is illustrated in accordance with the principles of the present invention is illustrated. Like the concrete form system 10, the concrete form system 100 is comprised of a plurality of concrete form board retaining brackets 112, each configured to retain a concrete form board 114 to a respective stake 116. Each concrete form board-retaining bracket 112 includes upper and lower stake retaining portions 118 and 120 that bias the stakes 116 against the outer surfaces 122 of the concrete form boards 114. The upper and lower stake retaining portions 118 and 120 define recesses 124 and 126 that engage an outer surface 128 of the stake 116 to hold the stake 116 relative to the bracket 112.

Spanning between the concrete form boards 114 is a flexible concrete form member 130 that is held between the brackets 112 and the form boards 114. The flexible member 130 is formed from a thin sheet of flexible material, such as sheet metal or plastic. The flexible member 130 is thick enough, however, to hold its shape once positioned between the ground fixed stake brackets 112 so as to allow for curved edges 132 to be formed in the resulting concrete pad 150.

As further illustrated in FIGS. 10 and 11, the bracket 112 includes an aperture 162 in the back portion 152. The aperture 162 is sized to receive a tab 164 formed in the outer surface 166 of the flexible member 130. The tab 164 may be formed by cutting and bending a portion of the flexible member 130 or by other means known in the art, such as welding. The tab 164 is positioned to fit within the aperture 162 when the flexible member 130 is positioned against the back portion 152 between the upper and lower portions 118 and 120 in order to prevent lateral movement of the flexible member 130 relative to the bracket 112 and the form board 122 after bracket 118 is secured to the metal or wooden stake (not shown).

FIG. 12 illustrates another embodiment of a pair of concrete form board corner brackets 230 and 232 each having a generally C-shaped configuration and sized to slide over respective ends 234 and 236 of concrete form boards 214 and 238, respectively. The corner bracket 230 includes a pair of hinge members 240 and 242 for engaging with corresponding hinge members 244 and 246, respectively, of corner bracket 232. The hinge members 240 and 242 are coupled to hinge members 244 and 246 with hinge pin 248, which may be in the form of a large gauge nail. Once inserted, the hinge members 240 and 242 can pivot relative to hinge members 244 and 246 to allow the two corner brackets 230 and 232 to be pivotable relative to one another, thereby allowing the formation of an angle between form board 214 and form board 238 to form a corner of concrete slab having a desired angle.

As noted above, and as further illustrated in FIG. 13, the upper and lower stake retaining portions 18 and 20 of the stake retaining bracket 12 can be used with a cylindrical stake 16. When using the cylindrical stake 16, the curved stake retaining portion 24′ of the recess 24 engages an outer surface of the stake 16 to bias it against form board 22.

As further illustrated in FIG. 14, the upper and lower stake retaining portions 18 and 20 of the stake retaining brackets 12 can alternatively be used with either a rectangular stake 17, such as a rectangular stake 17 formed from wood. When using a rectangular stake 17, the teeth of toothed edge 25 of the stake retaining portion 18 engages an outer surface of the stake 17 to bias it against form board 22.
