BACKGROUND OF THE INVENTION
The present disclosure relates to a routing jig and tenon fastener for creating concealed mortise and tenon joints. The use of this routing jig and tenon fastener can be applied to many objects and fixtures that need to be joined together. One example is attaching a table leg to a tabletop.
A mortise and tenon joint connect two pieces of wood or other material. Woodworkers have used mortise and tenons for thousands of years to join pieces of wood, mainly when the adjoining pieces connect at right angles. A mortise and tenon is also used in construction of buildings, furniture, or other household items.
In today’s world there are many methods for attaching a table leg or object to a table or surface and there are many brackets, fasteners, and corner plates on the market. A current example is Patent No.: U.S. 6,629,506 B2, Park, 2003 (“the ‘506 Patent”). The ‘506 Patent uses a threaded male and female coupling. The fasteners in the ‘506 Patent is exposed and visible. However, there are some situations that require the fastener to be hidden, attached to the very edge or the center of an object or the ability to join any two objects together using a mortise and tenon joint. This patent does not address these issues or situations.
There are other mortis and tenon methods to achieve a mortise and tenon joint, one example is Patent No: U.S. 10,690,164 B2, Stapleton, 2020 (“the ‘164 Patent”). The ‘164 Patent uses a more traditional approach using threaded holes in a tenon and fasteners a large screw to join two objects together. The ‘164 Patent method for joining two objects is mainly for large architectural construction and can be applied to smaller household products. However, the ‘164 Patent requires specific holes to be drilled at very precise locations. The ‘164 Patent leaves the fastener visible and the proper indexing and alignment of the mortis and tenon into the cavity unanswered. As shown by these examples and the ones that follow, existing methods of mortis and tenon joinery have limitations and are not suitable for the various situations as will be disclosed by the claimed invention.
First, traditional wood-to-wood mortise and tenon joinery requires a skilled craftsperson in the trade to cut the mortise and matching tenon. The challenge with using the traditional method is not every person can master these traditional skills as they take time and years to master. The cutting process is often very time consuming and meticulous, and a process that is not suited for novice, do-it-yourselfers, or mass production.
Second, wood-to-wood mortise and tenon joints are often large and can be visible. There are limitations in how deep or shallow a mortis and tenon can be created before the object receiving the mortise is structurally compromised.
Third, wood-to-wood mortis and tenon joints often use glue and other adhesives in addition to the joinery to ensure the mortise and tenon remain together. These additional adhesives add time, cost, and complexity to the joinery, and are permanent.
Fourth, metal-to-wood mortise and tenon connections require metalworking skills, woodworking skills, specific tools, and machinery, or metalworking tools. Therefore, metal-to-wood mortise and tenon connections tend to be a very costly and time-consuming.
Fifth, wood-to-wood joints are not as weather-resistant as metal-to-metal, metal-to-wood or synthetic plastics. Wood-to-wood joints will shrink or expand with varied weather, humidity and temperatures and therefore have the potential to leave a gap between the joints which may lead to further weakening of the joint.
Sixth, the position and location of a traditional mortise and tenon joint is limited by the object’s size or mass, the mortise position, and the second object position or mass. Mortis and tenons are often joined at ninety (90) degrees and require the mortis depth to be deep, and the tenon to be equal in length to the mortis depth.
Seventh, mortis and tenon joints are not designed to come apart, or to be easily disassembled. Therefore, the claimed invention has the advantage of being and reassembled repeatedly in instances, for example, of ease of transportation. Traditional mortise and tenon joints, on the other hand, are meant to stay joined together.
The current state of the art for attaching objects to another object involve the use of angled brackets with a combination of screws or corner plates. Dowls or threaded male-to-male screws can also be used. In all these approaches, one can see the fastener, and most of these techniques require glue. The current state of the art fasteners have limits to how an object can be attached to another object.
For example, a carpenter may want to build a table where the table legs are flush with the edge of the table or there is no visible fastener. In such an example, the carpenter would have to create a mortise and tenon using traditional methods of chiseling and carving out the mortise and tenon or use one of the known mortises and tenon joinery methods. Such methods include boring a mortise at the end of an object and then threading inserts, dowels, or biscuits to function as a mortise and tenon joint. Such methods create several issues such as requiring additional tools, skill, precision, custom jigs, and glue, and are often permanent. Further, using threaded inserts, pocket holes and screws, or dowls to join two objects together take time and labor, precision, additional woodworking or metalworking machinery, and tools to complete.
The method of using a long-threaded bolt, dowl or screw fastener requires the screws or dowls to be inserted into a table leg and then into a tabletop. Using a long-threaded bolt, dowl or screw fastener often creates a male and a female connection, and accordingly requires the craftsman to perfectly align and drill or bore out the holes in each object so they perfectly match up and join together properly.
In commercial applications, there are often industrial jigs and templates that assist with drilling and boring out holes in specific locations where the male and female connection join together. Large manufacturers have mastered this industrial jig and template method on a massive scale. However, these types of methods are out of reach for most consumers and businesses.
A non-traditional method that could be used to create a mortise and tenon is a router. A router is a power tool with a flat base and a rotating blade extending past the base. The spindle may be driven by an electric motor or by a pneumatic motor. The router routs, or hollows out, an area in hard material, such as wood or plastic. Routers are used most often in woodworking, especially cabinetry. Routers may be handheld or affixed to router tables.
If a carpenter or manufacturer wanted to make a mortise or tenon using a router, that craftsperson or manufacturer would have to create a jig to enable the router to travel along a specific path to cut out a mortise. Creating jigs is nothing new to a woodworker, as it is a common practice in the woodworking and manufacturing industry. The claimed invention is unique because it lowers the skill barrier of entry for using a jig for creating mortise and tenons joints. One need not be a woodworker or a manufacturer to create a mortise and tenon joint. The claimed routing jig and tenon fastener is for anyone desiring to make a mortise and tenon joint. The claimed routing jig and tenon fastener can create and install shallow mortises and tenons that would otherwise be structurally impossible to make using traditional methods. The claimed routing jig and tenon fastener can create mortise and tenon joints in any object or surface, like plastics, metals, and other materials. The claimed routing jig and tenon fastener expands the use and creation of mortise and tenon joints from traditional carpentry into everyday objects and applications. In addition, The claimed routing jig and tenon fastener saves the carpenter time and provides the carpenter options in what size mortise and tenon he or she may need for their project. This is possible because the routing jig can be fixed, or non-adjustable, or can also come in an adjustable embodiment in which two or more different sized tenon fasteners can be used in conjunction with the adjustable routing jig. The claimed routing jig and tenon fastener is unique in that the routing jig is also used to index and install the tenon, making the claimed invention a perfect mortise and tenon for anyone who wants to use the mortise and tenon joinery method.
A non-adjustable fixed routing jig can be formed by a fixed square plate material that in most cases would be made out of metal for durability but could be made out of various materials depending upon property characteristics such as weight, hardness, durability, ease of manufacture or cost. Such materials could be metal, wood, carbon fiber, plastic, or a host of natural, synthetic, or composite materials. The non-adjustable fixed routing jig would then have a means to index jig on a corner or edge of the flat piece of material, such as indexing tabs, a lip or a rail where the mortise can be created by a router tool, and the means to attach the routing jig to said flat piece of material to form a stable platform for the router tool, such as plurality of screw holes, slots or grooves.
In an adjustable form, the routing jig is comprised of an adjustable mortise mounting member and an adjustable indexing member. The adjustable mortise mounting member would have a plurality of plurality of screw holes, slots, or grooves to attach the adjustable mortise mounting member to a solid surface such as a tabletop. The adjustable mortise mounting member also has a plurality of grooves, notches, and lips to connect the adjustable mortise mounting member and the adjustable indexing member. The adjustable indexing member also contains a plurality of indexing tabs to properly align and index the routing jig on a solid surface, such as a tabletop. The adjustable indexing member also contains a plurality of grooves, notches, and lips to connect the adjustable indexing member to the adjustable mortise mounting member.
There is another non-traditional method that could be used being a computer numerical control (CNC) system. A CNC machine is a motorized maneuverable tool often incorporating a motorized maneuverable platform both of which are controlled by a computer according to specific input instructions. Instructions are delivered to a CNC machine in the form of a sequential program of machine control instructions. In this example, a programmer could program the CNC machine with instructions to carve out a mortise. The limitation with this method is that the size of the CNC path and object being milled is constrained. Installing and joining the object together are left unanswered. In addition, CNC systems are large, technically challenging, and expensive systems for creating a mortise and tenon joint which leave indexing and installation unresolved. Therefore, the claimed routing jig and tenon fastener for creating concealed mortise and tenons is superior to the CNC tool because the claimed invention solves the large, expensive and complex problem of using a CNC, and simplifies the creation of mortise and tenons and, at the same time, provides the mortise and tenon joinery method to everyone at a cheaper more affordable price.
The claimed routing jig and tenon fastener for creating concealed mortise and tenons on any object eliminates or minimizes limitations with conventional and nonconventional mortise and tenon joinery. Through research and development, the following routing jig and tenon fasteners, process and methods described below have been developed.
BRIEF SUMMARY OF THE INVENTION
The routing jig and tenon fastener and method for creating concealed mortise and tenons includes a routing jig for creating the mortise, and a tenon fastener. These two elements of the embodiment work together to form a mortise and tenon joint, being the fastener connection.
The routing jig is easily maneuverable and can be fixed or non-adjustable having a sing sized and corresponding tenon fastener, or the routing jig can be adjustable to different sizes and quadrilateral shapes to allow for a smaller or larger mortise to be carved out by a router tool. The routing jig also has the ability to index and self-center on a corner or edge where a mortise can be created. The jig includes a means to attach the routing jig to any surface, and therefore the routing jig becomes a guide for a router tool to create a mortise in the attached surface.
The routing jig is also used as an indexing guide for aligning and attaching the uniquely designed quadrilateral tenon fastener to an object’s surface. The tenon fastener allows, for example, a table leg to become a perfect tenon for the mortise created by the routing jig. Using the routing jig to create the mortise and as a guide to attach the tenon fastener to any object’s surface allows the tenon fastener to be concealed from sight. The tenon fastener is designed to fit into the mortise created by the routing jig, thus creating a perfect mortise and tenon joint and union of the two objects.
The tenon fastener is uniquely designed and engineered to work in conjunction with the routing jig. The tenon is sized to fit within the quadrilateral mortise created by the routing jig. The tenon also has been engineered with specific holes, slots, and grooves as mounting options for attaching table legs or other objects that need to have a mortise and tenon joint. The specifically placed holes, slots, or grooves allow for different sized screws and fasteners to be installed flush to the tenon fastener. The tenon fastener can be made from steel, plastic, or other material.
The routing jig and tenon fastener for creating concealed mortise and tenons allows unexperienced woodworkers or manufacturers to create a concealed mortise quickly, accurately, and more affordably than other techniques known in the industry and in the marketplace. The routing jig assists in the perfect placement of the tenon fastener so that it can attach to any surface and object that would be almost impossible if one were to use traditional or other non-traditional mortise and tenon joinery.
A summary of the invention in the broadest form is a routing jig and tenon fastener that has a means to index and provide a router the proper pathway to create a mortise in any surface such as a tabletop, as well as an indexing and installation guide for a attaching a corresponding quadrilateral tenon fastener to an object such as a table leg. This routing jig and tenon fastener allows any object to be joined together using the mortise and tenon joinery method.
BRIEF SUMMARY OF THE PROCESS AND METHOD
The routing jig and tenon fastener process and method create a new way for a carpenter, metal worker, furniture maker, or do-it-yourselfer to create, build and assemble mortise and tenons joints. This method does not require any traditional training in the woodworking or metal working arts. The routing jig and tenon fastener process and method expands the accessibility and adoption of mortise and tenon joints to more individuals and products because the invention has simplified the process for creating and applying mortise and tenons to objects.
