## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is closely related to and claims benefit from U.S. Provisional Application Ser. No. 60/714,776 filed Sep. 7, 2005.


FIELD OF THE INVENTION
The present invention relates, in general, to a masonry aid, and more particularly, to an aid for protecting not only a workers clothing but also for providing protection against bruising and scraping of the thigh and leg of the worker.
BACKGROUND OF THE INVENTION
Many masons, rock cutters and others working with stones, bricks and rocks often experience bruising and scraping when working, as well as having extreme wear to clothing. Individuals often place the rock or stone with which they are working on the upper thigh portion of the leg to break or cut such rock or stone with a rock hammer. As this process is most effective for cutting or breaking rocks, the leg of the worker needs protection since the very action of cutting the stone can very easily bruise the thigh or scrape it. Further, the clothing of the worker must bear considerable strain as the stone abrades the clothing as it is being hit with the hammer.
Thus, it would be advantageous if there were a product that could protect both the worker's leg and clothing when doing masonry work with stone or rock so as to reduce the wear and tear to both the clothing and the worker's leg.
SUMMARY OF THE INVENTION
In a first aspect the present invention provides an apparatus for protecting a mason or a stone worker's leg and clothing while working. The apparatus comprises a leg guard having a predetermined configuration. Such leg guard includes at least one layer having a predetermined shape and being formed from a first predetermined material, a first side of the first layer for contacting a user's leg. There is at least one strap disposed on and engageable with a top end of such leg guard for securing the leg guard to such user's belt and at least one leg strap disposed on and connected to each side of the leg guard for securing the leg guard to such user's leg.
OBJECTS OF THE INVENTION
It is, therefore, one of the primary objects of the present invention to provide an apparatus for protecting a mason or stone worker's leg while working.
Another object of the present invention is to provide an apparatus for protecting the clothing of a mason or stone worker while working.
Still another object of the present invention is to provide an apparatus for protecting a mason or stone worker's leg and clothing while working that is easy to use.
Yet another object of the present invention is to provide an apparatus for protecting a mason or stone worker's leg and clothing while working that is relatively inexpensive.
These and various other objects and advantages of this invention will become apparent after a full reading of the following detailed description, particularly, when read in conjunction with the attached drawings as described below and the appended claims.

BRIEF DESCRIPTION OF THE PRESENTLY PREFERRED AND ALTERNATE EMBODIMENTS OF THE INVENTION
Prior to proceeding with the more detailed description of the present invention it should be noted that, for the sake of clarity, identical components which have identical functions have been designated by identical reference numerals throughout the several views illustrated in the drawings.
In a first aspect the present invention provides an apparatus, generally designated 10, for protecting a mason or a stone worker's leg and clothing while working. The apparatus 10 comprises a leg guard, generally designated 20, having a predetermined configuration. Such leg guard 20 includes a first layer 2 having a predetermined shape and being formed from a first predetermined material, a first side of the first layer 2 for contacting a user's leg. A second layer 4 is formed from a second predetermined material and has a first side disposed adjacent and engageable with a second side of the first layer 2. A third layer 6 is formed from a third predetermined material and has a first side disposed adjacent and engageable with a second side of the second layer 4. The third layer 6 is for contacting such stone and rock being worked on. There is a plurality of first straps 12 disposed on and engageable with a top end of such leg guard 20 for securing the leg guard 20 to such user's leg. Such plurality of first straps 12 and such second straps 14 are adjustable so as fit securely against a person's leg.
It should be noted that although this is referred to as a lea guard, as is clearly seen in FIG. 3, that such guard is really a thigh guard since that is the area of the lea that the stone worker uses to hold the stone or brick when it is being hammered and that is the area that requires protection both for the worker and for his clothes.
It is presently preferred that such predetermined configuration of the leg guard 20 is substantially rectangular. Such substantially rectangular configuration 22 of the leg guard 20 further includes a smaller substantially rectangular portion 24 having arcuate portions and is engageable with a top end of the substantially rectangular 22 leg guard 20, the smaller substantially rectangular portion 24 extends outwardly from the substantially rectangular configuration 22 for providing protection for an upper leg and hip area and for helping prevent debris from slipping between the leg guard and such user's clothing.
The plurality of first straps 12 are disposed on and engageable with a top end of the smaller substantially rectangular portion 24 that extends outwardly from the substantially rectangular configuration 22 of the leg guard 20. Such plurality of first straps 12 are placed over and around such user's belt and are secured using metal snaps.
The plurality of second straps 14 are connected to one side of the leg guard 20 and have male snaps 26 on each end of the plurality of the second straps 14 while the plurality of second straps 14 connected to an opposite side of the leg guard 20 have female snaps 28 on each end of the plurality of second straps 14. The plurality of second straps 14 are placed around such user's leg and each of the male snaps 26 is secured to the female snaps 28 of a matching strap 14. Such male snaps 26 and such female snaps 28 are formed of plastic.
It is also presently preferred that such first predetermined material for the first layer 2 is an elastomeric material and, further, that such elastomeric material is selected from natural rubber, synthetic rubber, plastic and combinations thereof. It is preferred that such elastomeric material is a soft synthetic rubber.
Further as seen in FIGS. 4 and 5 such elastomeric material has a plurality of grooves 32 disposed therein for providing ventilation to such user's leg. It is within the scope of the invention that such grooves can be horizontal, vertical or even crosshatched; however, it is preferred that such plurality of grooves 32 are disposed vertically on the elastomeric material of the first layer 2 of the leg guard 10.
The third predetermined material for such third layer 6 is a durable, flexible material and is selected from at least one of natural rubber, synthetic rubber, plastic and combinations thereof. Such material has to be durable because is comes in contact with stones, brick or rocks that are being hit with a hammer. Such exterior surface of such third predetermined material may have cross hatched grooves so as to engage the rock, brick or stone being worked on from slipping.
The second predetermined material of the second layer 4 is a soft rubber material. This material is used to provide a cushioning effect on the leg when such hammering takes place.
In an alternate embodiment of the invention, as seen in FIG. 4, such apparatus 10 further includes a fourth layer 6 that is disposed intermediate the first layer 2 and the second layer 4. Such fourth layer 8 is selected from one of nylon and canvas.
The different layers (first layer 2, second layer 4, third layer 6 and fourth layer 8) of such apparatus 10 are secured together by means of stitching and metal rivets 34. It is preferred that metal rivets 34 are used to secure the layers together since the apparatus takes considerable abuse from the stones, rocks or bricks being hit with a hammer and metal rivets 34 are stronger than stitching is.
While a presently preferred embodiment and alternate embodiments of the present invention has been described in detail above, it should be understood that various other adaptations and/or modifications of the invention can be made by those persons who are particularly skilled in the art without departing from either the spirit of the invention or the scope of the appended claims.
