The disclosure relates to jig devices and more particularly pertains to a new jig device for smoothing treads on concrete steps. The device includes a riser adjustment that has a slidably adjustable height to accommodate riser heights between 5.0 inches and 8.0 inches. Additionally, the device includes a leg that rests on top of the riser for maintaining a jig at a fixed angle for finishing the tread.
The prior art relates to jig devices and more particularly pertains to a new jig device for smoothing treads on concrete steps. The prior art discloses a variety of jig devices that includes an arcuate jig for forming planes that intersect at a curve. The prior art discloses a masonry step jig that includes a wheel for rolling on top of a riser and the jig that is engaged to the wheel for smoothing a tread on a step. The prior art discloses a stair screed that includes a sloped portion that is insertable under a form on a riser adjacent to a tread being smoothed. Additionally, the prior art discloses a jig that has a riser adjustment being coupled there to which rides on top of a riser adjacent to a tread being smoothed with the jig.
An embodiment of the disclosure meets the needs presented above by generally comprising a jig that is elongated to a predetermined length to extend along a full length of a tread on a concrete step for smoothing the tread before the concrete has cured. A riser adjustment is hingedly coupled to the jig and the riser adjustment unit abuts a concrete form that is positioned against the riser of the step adjacent to the tread upon which the jig is positioned. A leg is hingedly coupled to the jig and the leg slidably engages the riser adjustment such that each of the leg, the riser adjustment and the jig forms a triangle. The leg has engages a top of the riser of the step adjacent to tread upon which the jig is positioned for keeping the jig at a fixed angle on the tread.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A riser adjustment 32 is provided and the riser adjustment 32 is hingedly coupled to the jig 12. The riser adjustment 32 unit abuts the concrete form 28 that is positioned against the riser 30 of the step adjacent with respect to the tread 14 upon which the jig 12 is positioned. Additionally, the riser adjustment 32 has an adjustable height to accommodate a variety of riser 30 heights. The riser adjustment 32 comprises a first portion 34 that has a primary end 36, a secondary end 38 and a back surface 40 extending therebetween. The primary end 36 is hingedly coupled to the top side 22 of the outer surface 20 of the jig 12 at a point located adjacent to the sloped portion 26 of the top side 22. Additionally, the back surface 40 has graduated indicia 42 printed thereon which define a graduated scale 44 extending between the primary end 36 and the secondary end 38. The graduated scale 44 may comprise a ruler measuring between 5.0 inches and 8.0 inches.
The riser adjustment 32 includes a second portion 46 that has an upper end 48 and a lower end 50. The second portion 46 has a slot 52 extending therethrough and the slot 52 extends substantially between the upper end 48 and the lower end 50. A first fastener 54 extends through the slot 52 and engages the back surface 40 of the first portion 34 such that the second portion 46 is slidably coupled to the first portion 34. The first fastener 54 is tightenable for retaining the second portion 46 at a selected height with respect to the first portion 34. The first fastener 54 may comprise a nut and a bolt or other type of releasable, mechanical fastener. Additionally, the riser adjustment 32 includes a foot 56 that is hingedly coupled to the upper end 48 of the second portion 46 having the foot 56 extending forwardly away from the second portion 46.
A leg 58 is provided and the leg 58 is hingedly coupled to the jig 12. Additionally, the leg 58 slidably engages the riser adjustment 32 such that each of the leg 58, the riser adjustment 32 and the jig 12 forms a triangle. The leg 58 has a protrusion 60 extending rearwardly beyond the riser adjustment 32 such that the protrusion 60 can lie on top of the riser 30 of the step adjacent to tread 14 upon which the jig 12 is positioned. In this way the jig 12 can be retained at a fixed angle on the tread 14 for finishing the concrete at a consistent angle. The riser adjustment 32 may be adjustable to a length ranging between approximately 5.0 inches and 8.0 inches. The protrusion 60 may have a length of at least 1.5 inches.
The leg 58 has a front end 62 and a back end 64, and the leg 58 has a bend 66 that is positioned closer to the back end 64 than the front end 62 to define the protrusion 60 between the bend 66 and the back end 64. The leg 58 has a slot 68 extending therethrough and the slot 68 in the leg 58 extends from the bend 66 toward the front end 62. The foot 56 of the riser adjustment 32 abuts a bottom surface 69 of the leg 58 having the foot 56 being aligned with the slot 68 in the leg 58. A second fastener 68 extends through the slot in the leg 58 and engages the foot 56 such that the riser adjustment 32 is slidably coupled to the leg 58. The second fastener 68 is tightenable for retaining the foot 56 at a selected point along the leg 58. Additionally, the second portion 46 of the riser adjustment 32 is aligned with the bend 66 in the leg 58 when the riser adjustment 32 is slid fully rearwardly in the slot in the leg 58.
In use, the riser adjustment 32 is adjusted to the desired height based upon the height of the riser 30 on the staircase being built. The first fastener 54 is tightened to retain the riser adjustment 32 at the desired height. As is most clearly shown in
The sloped portion 26 of the jig 12 is inserted beneath the form 28 on the positioned against the riser 30 adjacent to the tread 14 that is being smoothed with the jig 12. Additionally, the protrusion 60 on the leg 58 rests on top of the form 28 positioned against the riser 30. In this way the jig 12 is retained at a consistent angle for smoothing the tread 14 upon which the jig 12 is positioned. Thus, the tread 14 of concrete stairs can be precisely smoothed for the best possible comfort and safety for people that will walk on the concrete stairs.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
