CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. Design Application No. 29466535, filed Sep. 9, 2013 and Mexican Application No. MX/E/2014/092558, filed Dec. 19, 2014, which are hereby incorporated by reference, to the extent that they are not conflicting with the present application. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The invention relates generally to assembly systems and methods and more particularly to a non-penetrating assembly system and method using grooves and wedges. 
         [0004]    2. Description of the Related Art 
         [0005]    With today&#39;s living spaces becoming smaller and storage space at a premium, the need for efficient use of those spaces has become more important. Additionally, with the costs of fuel and transportation increasing, it is ever more important to realize efficiencies in the shipping of goods. The less air shipped in a package the better. 
         [0006]    Thus, there is a need for furniture (or other similar goods) of all kinds that use an innovative assembly system that allows the furniture to be easily assembled and disassembled multiple times so you can transport it or store it flat; to introduce or remove it in complicated and reduced current spaces; to lower the costs of transportation and storage; to make all of this easy without discrediting its aesthetic appearance and good functionality. 
       BRIEF SUMMARY OF THE INVENTION 
       [0007]    This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter. 
         [0008]    In one exemplary embodiment, an assembly system and method is provided that allows one to join for example two flat pieces at 90 degrees (perpendicular), without cutting all the way through the receiving piece, by simply using grooves and wedges. The unique feature of the system is the way in which the pieces are joined. No full penetration of a piece with the other, no glued parts or screws or nails, rivets or any metal clips. 
         [0009]    Using the system and method disclosed herein, a strong and rigid assembly is accomplished by the use of grooves that are locked together and are secured by a wedge inserted into a recess with a ramp with an inclination of, for example, 5 degrees. This rigid assembly is achieved only with the use of grooves and wedges and in most cases requires only one wedge, so that you can easily assemble and disassemble pieces multiple times without damage or wear to the furniture. 
         [0010]    The system and method disclosed may be used for furniture assembly to obtain economical, flat transport and storage, and easy installation that requires no hardware. It can be used for all kinds of furniture such as chairs, tables, benches, shelves, and so on. For example, it can be used to attach a table top with the table legs or any number of pieces of furniture where it is required to have a firm assembly without one of the surfaces being perforated completely by another. 
         [0011]    The above embodiments and advantages, as well as other embodiments and advantages, will become apparent from the ensuing description and accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0021]    What follows is a detailed description of the preferred embodiments of the invention in which the invention may be practiced. Reference will be made to the attached drawings, and the information included in the drawings is part of this detailed description. The specific preferred embodiments of the invention, which will be described herein, are presented for exemplification purposes, and not for limitation purposes. It should be understood that structural and/or logical modifications could be made by someone of ordinary skills in the art without departing from the scope of the invention. Therefore, the scope of the invention is defined by the accompanying claims and their equivalents. 
         [0022]    Reference will now be made to  FIGS. 1-3 .  FIG. 1  is an isometric view of a recess of a first assembly element, according to an embodiment.  FIG. 2  is a top view of the recess from  FIG. 1 .  FIG. 3  is a cross section view of the recess from  FIG. 2  along cutting plane A: A. 
         [0023]    As can be seen in  FIGS. 1-3 , the recess  10  has a floor  15 , which is preferably flat, a straight edge of greater length  11  and, opposite to it, an edge  12  with a ramp  13  having a certain inclination  13   a  (preferably  5  degrees). Preferably over its entire length, as shown, the longest straight edge  11  is preferably configured to have a fluting/undercut  16 . It should be noted that the undercut/fluting  16  creates a lip  14  extending inwards, as better seen in  FIG. 3 . 
         [0024]    It should be noted in  FIG. 3  that some examples of dimensional relationships between elements of the recess  10  and a dimension (e.g., thickness) of the first assembly element  17  are provided. Again, these are examples only, thus other sizes for the recess  10  and its elements (e.g., lip  14  or fluting/undercut  16 ) may be adopted depending on such factors as the strength or thickness of the materials from which the first assembly element  17  is made (e.g., wood, aluminum, plastic, glass, etc.). 
         [0025]    It should be observed that the recess  10  is formed into the first assembly element  17  such that it does not penetrate completely the first assembly element  17 . Because of that, the recess  10  has a floor  15 , and, while the recess  10  can be seen from one side  17   a  of the first assembly element  17 , it cannot be seen from the opposite side  17   b,  if the first assembly element  17  is made from an opaque material. This has significant advantages, such as to mask the joint created using recess  10 , when, for example the joint is used in a furniture piece. Another advantage is that floor  15  may contribute to the strength of the resulting joint, as it will be apparent from the below description referring to  FIGS. 7-9 . 
         [0026]    One of ordinary skill in the art would understand that various suitable processes may be adopted to form the recess  10  into the first assembly element  17 . The list of such processes may include cutting, carving, casting, and so on. Also, it should be noted that an overcut  80  ( FIG. 2 ) may be used to facilitate the insertion of the second assembly element  20  into the recess  10 . 
         [0027]    One of ordinary skill in the art would further understand that the recess  10  could for example also be a structure associated with and/or extending from one of the faces (e.g.,  17   a ) of the first assembly element  17 , thus not being embodied into the first assembly element  17  as preferred and depicted in  FIG. 3 , while still fulfilling a similar function. Such variation and other similar variations would not depart from the scope of this disclosure. 
         [0028]    Reference will now be made to  FIGS. 4-6 .  FIG. 4  is an isometric view of a second assembly element, according to an embodiment.  FIG. 5  is a top view of the front face of the second assembly element from  FIG. 4 .  FIG. 6  is a cross section view of the second assembly element from  FIG. 5  along cutting plane B: B. 
         [0029]    The second assembly element  20  is the other piece that will form the assembly by joining with the first assembly element  10 , as it will be described in detail hereinafter when referring to  FIGS. 7-10 . As shown, the second assembly element  20  may have a front face  21  and a back face  22 , and a longitudinal slot/groove  23  on its front face  21  and near the bottom  29  of the second assembly element  20 . As shown, the presence of the longitudinal slot/groove  23  creates a flange  24  between the bottom  29  and the longitudinal slot  23  of the second assembly element  20 . 
         [0030]    The longitudinal slot/groove  23  of the second assembly element  20  is preferably shaped and sized to fit snugly over the lip  14  of the first assembly element  10 . The flange  24  is preferably shaped and sized to fit snugly into the fluting  16  of the first assembly element  10 . 
         [0031]    As shown, the back face  22  has a shoulder  25 , which is preferably shaped and sized to receive snugly a portion of the wedge  30  (see  FIG. 9 ), in order to lock the assembly, as it will be described hereinafter when referring to  FIGS. 7-10 . Element  25 , prevents the wedge from falling out, should it loosen. 
         [0032]    It should be noted that in  FIGS. 5-6  some examples of dimensional relationships between elements of the second assembly element  20  are provided. Again, these are examples only, thus other sizes may be adopted depending on such factors as the strength of the material and the thickness from which the second assembly element  20  is made (e.g., wood, aluminum, plastic, glass, etc.). 
         [0033]    Reference will now be made to  FIGS. 7-10 .  FIGS. 7-9  illustrate the process of joining the first and the second assembly elements, according to an embodiment.  FIG. 10  is a top view of the assembly resulting from joining the first and the second assembly elements as depicted in  FIGS. 7-9 . 
         [0034]      FIG. 7  is an isometric view where the first step of the assembly process is shown. As shown, first, the second assembly element  20  is inserted into the recess  10  of the first assembly element  17  ( FIG. 3 ), such that preferably the bottom  29  of the second assembly element  20  touches the floor  15  of recess  10 . Next, as shown in  FIG. 8 , the second assembly element is pushed to slide toward the straight edge of greater length  11  of recess  10  and until the lip  14  of the first assembly element  10  enters the longitudinal slot  23  (see  FIG. 7 ) of the second assembly element  20 , and the flange  24  of the second assembly element  20  enter the fluting/undercut  16  of the first assembly element  10 . Next, as shown in  FIG. 9 , for securing the assembly  40  of both pieces, a wedge  30  is inserted into the recess  10  between the recess  25  of the second assembly element  20  and the ramp  13  of recess  10  and pushed to slide (from left to right (B) in  FIG. 9 ) to press hard enough onto the second assembly element  20 , to keep it in place and thus make the assembly  40  secure. As it can be seen in the top view in  FIG. 10 , angle  13   a  (e.g., 5 degrees) of ramp  13  corresponds and cooperates with the slope of the wedge  30  to create enough pressure to be introduced to second assembly element  20 . It should be also noted that recess  25  contributes to preventing the wedge  30  from escaping the construct. It should be noted as well that more than one wedge  30  may be used if the parts are configured appropriately. 
         [0035]    Thus, it should be apparent that the system and method disclosed herein allows one to join for example two flat pieces of different or similar thicknesses at  90  degrees (perpendicular), without puncture or penetration, by simply using one or more wedges. The unique feature of the system is the way in which the pieces are joined. No full penetration of a piece with the other, no glued parts or screws or nails, rivets or any metal clips. 
         [0036]    Using the system and method disclosed herein, a strong and rigid assembly may be accomplished by the use of grooves that are locked together and are secured by a wedge inserted in a recess with a ramp with an inclination of, for example, 5 degrees. 
         [0037]    Again, the system and method disclosed herein may be used to assemble furniture. For example, the first assembly element  17  having the recess  10  may be the flat top of a table and the second assembly element  20  may be a leg or a leg set of the table. However, it should be understood that the system and method disclosed herein may also be used to assemble other items such as art pieces, toys, and so on. 
         [0038]    It should be noted that a ninety degrees (perpendicular) joint was disclosed herein. However, it should be understood that a deviation from the perpendicular configuration (e.g., 95 degrees) may be adopted if needed, by correspondingly adjusting the surfaces of the interlocking elements described. 
         [0039]    It may be advantageous to set forth definitions of certain words and phrases used in this patent document. The phrases “associated with” and “associated therewith,” as well as derivatives thereof, may mean to include, be included within, interconnect with, contain, be contained within, connect to or with, couple to or with, be communicable with, cooperate with, interweave, juxtapose, be proximate to, be bound to or with, have, have a property of, or the like. 
         [0040]    As used in this application, “plurality” means two or more. A “set” of items may include one or more of such items. Whether in the written description or the claims, the terms “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of,” respectively, are closed or semi-closed transitional phrases with respect to claims. Use of ordinal terms such as “first,” “second,” “third,” etc., in the claims to modify a claim element does not by itself connote any priority, precedence or order of one claim element over another or the temporal order in which acts of a method are performed. These terms are used merely as labels to distinguish one claim element having a certain name from another element having the same name (but for use of the ordinal term) to distinguish the claim elements. As used in this application, “and/or” means that the listed items are alternatives, but the alternatives also include any combination of the listed items. 
         [0041]    Throughout this description, the embodiments and examples shown should be considered as exemplars, rather than limitations on the apparatus and procedures disclosed or claimed. Although many of the examples involve specific combinations of method acts or system elements, it should be understood that those acts and those elements may be combined in other ways to accomplish the same objectives. With regard to flowcharts, additional and fewer steps may be taken, and the steps as shown may be combined or further refined to achieve the described methods. Acts, elements and features discussed only in connection with one embodiment are not intended to be excluded from a similar role in other embodiments. 
         [0042]    Although specific embodiments have been illustrated and described herein for the purpose of disclosing the preferred embodiments, someone of ordinary skills in the art will easily detect alternate embodiments and/or equivalent variations, which may be capable of achieving the same results, and which may be substituted for the specific embodiments illustrated and described herein without departing from the scope of the invention. Therefore, the scope of this application is intended to cover alternate embodiments and/or equivalent variations of the specific embodiments illustrated and/or described herein. Hence, the scope of the invention is defined by the accompanying claims and their equivalents. Furthermore, each and every claim is incorporated as further disclosure into the specification and the claims are embodiment(s) of the invention.
