CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application claims priority to provisional U.S. patent application entitled, Universal Clamp, filed Feb. 20, 2004, having an application No. 60/545,946 now pending, the disclosure of which is hereby incorporated by reference in its entirety. 
     
    
     FIELD OF THE INVENTION  
       [0002]     The present invention relates generally to retaining mechanisms. More particularly, the present invention relates to a clamp that includes a top and bottom portion such that these pieces are mated at one end and pivotally connected at another.  
       BACKGROUND OF THE INVENTION  
       [0003]     There are many clamping devices that exist for retaining wires and the like for many different applications. They include cushioned and uncushioned loop clamps, hose clamps and snapper type clamps, among others. The loop clamp is common in the aircraft and automotive industries, for both original equipment manufacturing as well as aftermarket sectors. These clamps are often used to attach pods and splitters to the airframe. The cushioned clamps are sometimes used to dampen vibration.  
         [0004]     There are many disadvantages to the typical loop clamp. The clamps are difficult to install and therefore require more time and effort. The typical loop clamp is ergonomically undesirable in that repeated installation of the clamp results in carpal tunnel injuries for the operators. Also, many loop clamps are heavy and cannot be rotated or stacked when installed.  
         [0005]     Most clamps require screws or bolts to keep the clamp locked. Others have two separate pieces that need to be locked at both ends with screws or bolts. Snapper type clamps require pliers for the installation. Thus, these all require tools for installation.  
         [0006]     These clamps have a limited life in that repeated use may not be possible. The frequent removal and installation may cause fatigue on the clamp band and may lead to complete failure of the clamp. This is very undesirable especially in aircraft applications. In addition, such failures result in increased cost.  
         [0007]     The ability to reuse clamps is desired for many reasons. However, traditional clamps may not be reused on engines, such as aircraft turbojets, because of the immense heat cycling and vibration. The metal fatigues and the cushion deforms. Other areas where traditional clamps may not be reused include pressure lines of hydraulic systems, aircraft engine pylons and wings.  
         [0008]     Installing and removing wires, ducts and the like from traditional clamps can be cumbersome. Traditional loop clamp openings are not very wide and require a considerable amount of effort to be opened. Once opened, conventional loop clamps undergo metal fatigue and are subject to additional fatigue or failure when closed. In addition, the cushions that often are used with these clamps slip off or do not provide the amount of cushioning required, leading to greater abrasion and vibration.  
         [0009]     Accordingly, it is desirable to provide a method and apparatus for a clamping assembly that is easy to install, ergonomically favorable, lockable, stackable, rotatable and lightweight. Moreover, it is desirable that the clamp be reused numerous times, in any type of application, without the likelihood of fatigue or failure, which also reduces cost.  
       SUMMARY OF THE INVENTION  
       [0010]     The foregoing needs are met, to a great extent, by the present invention, wherein in one aspect an apparatus is provided that in some embodiments allows for easy installation, is ergonomically favorable, lockable, stackable, rotatable, lightweight, inexpensive and can be used repeatedly under any application.  
         [0011]     In accordance with one embodiment of the present invention, a universal clamp apparatus includes two mating devices that engage at one end and pivotally connect at the other end to form a hinge.  
         [0012]     In accordance with another embodiment of the present invention, a method of clamping wires together, or other materials, using the universal clamp device includes affixing the clamp around the wires and locking the clamp in place, without the use of tools.  
         [0013]     In accordance with yet another embodiment of the present invention, a system for securing wires to an object includes securing the first ends of a top member and a bottom member together and pivotally connecting the second ends of the top member and the bottom member.  
         [0014]     There has thus been outlined, rather broadly, certain embodiments of the invention in order that the detailed description may be better understood, and in order that the present contribution to the art may be better appreciated. There are, of course, additional embodiments of the invention that will be described below and which will form the subject matter of the claims appended hereto.

     DETAILED DESCRIPTION  
       [0021]     The invention will now be described with reference to the drawing figures, in which like reference numerals refer to like parts throughout. An embodiment in accordance with the present invention provides a universal clamp that allows for easy installation, is ergonomically favorable, lockable, stackable, rotatable, lightweight, inexpensive and can be used repeatedly.  
         [0022]      FIG. 1  is an isometric view of the preferred embodiment of the present invention. This figure depicts the device having a bottom half clamp  10 . The bottom half clamp  10  has a bottom planar surface  12 . The bottom planar surface  12  has an opening  14 , configured to mate or accept another device at a first planar end  15 , and a second planar end  16 . Located on the bottom planar surface  12  are edges defining an opening or a bottom planar hole  18 .  
         [0023]     The bottom half clamp  10  has a first curved surface  20 . The first curved surface  20  has a first curved end  22  that attaches to the second planar end  16  of the bottom planar surface  12 . The first curved surface  20  also has an opposing second curved end  24  and a curved opening or hole  26 . The second curved end  24  is adjacent to a second curved surface  28 . The second curved end  24  includes a first end  30  and a flanged end  32 .  
         [0024]     The flanged end  32  of the second curved surface  28  has a width greater than that of the second curved surface  28 . The flanged end  32 , in the preferred embodiment, forms a T-shape object to the remaining portion of the second curved surface  28 .  
         [0025]     The bottom half clamp  10  mates with a top half clamp  40  to form the preferred embodiment of the present invention. The top half clamp  40  has a first curved surface  42  with a first top end  44  and a second top end  46 . The first curved surface  42  has a top opening  48  to allow for insertion of the flanged end  32 .

         [0026]     The top half clamp  40  also contains a top planar surface  58 . Located on the top planar surface  58  are edges defining an opening or a top planar hole  56 . A top planar end  62  of the top planar surface  58  has an extension or protrusion  64  that mates with the opening  14  of the bottom half clamp  10 .  
         [0027]     The present invention also includes a housing  66  with a molded wedge  68  at one end, that prevents the cables or wires enclosed in the clamp from slipping out of the enclosure. Opposing the molded wedge  68  on the housing  66  is the other end  70  of the housing  66 . The housing  66  may first be slid onto the bottom planar surface  12  and brought over the bottom half clamp  10  and the top half clamp  40  until the molded wedge  68  of the housing  66  is adjacent to the top planar surface  58 . In the alternative, the housing  66  may first be slid onto the top planar surface  58  and brought over the top half clamp  40  and the bottom half clamp  10  until the housing  66  at end  70  is adjacent to the bottom planar surface  12 .  
         [0028]      FIG. 2  illustrates the preferred embodiment of the present invention, in an unassembled position. This figure illustrates the bottom half clamp  10  with the opening  14  at one end. The bottom half clamp  10  has a bottom planar surface  12  with the second planar end  16 . Located on the bottom planar surface  12  are edges defining an opening or a bottom planar hole  18 .

         [0029]     The top half clamp  40  has a first curved surface  42 . The first curved surface  42  has a first top end  44 . The first curved surface has a top opening  48  that accepts the flanged end  32  of the bottom half clamp. Adjacent to the first curved surface  42  is the second curved end  50 . Located on the second curved surface  50  is an opening or hole  54 . Adjacent the second curved surface  50  is the top planar surface  58 . The top planar surface  58  has one end  60  and a top planar end  62  that contains a protrusion  64  that mates with the opening  14  of the bottom half clamp  10 .  
         [0030]     This figure also depicts an optional housing  66  with its molded wedge  68  at one end that prevents the cables or wires enclosed in the clamp from slipping out of the enclosure. Opposing the molded wedge  68  on the housing  66  is the other end  70  of the housing  66 . The housing  66  is slid onto the bottom planar surface  12  and brought over the bottom half clamp  10  and the top half clamp  40  until the molded wedge  68  of the housing  66  is adjacent to the top planar surface  58 . In the alternative, the housing  66  may first be slid onto the top planar surface  58  and brought over the top half clamp  40  and the bottom half clamp  10  until the housing  66  at end  70  is adjacent to the bottom planar surface  12 .  
         [0031]      FIG. 3  is a side view of the assembled clamp where the bottom half clamp  10  is pivotally attached to the top half clamp  40 . The bottom half clamp has the bottom planar surface  12 , with the opening  14  and the bottom planar hole  18 . Second planar end  16  of the bottom planar surface abuts the first curved end  22  of the first curved surface  20 . The first curved surface  20  has a second curved end  24  that attaches with end  30  of the second curved surface  28 . Second curved surface  28  has a flanged end  32  that mates with the top half clamp  40 .  
         [0032]     Top half clamp  40  has a first curved surface  42  with a first top end  44 . The first curved surface  42  has a second top end  46  that lies adjacent to end  52  of the second curved surface  50 . Located on the second curved surface  50  is a hole  54 . Second curved surface  50  has another end  60  that attaches to the top planar surface  58 . The top planar surface  58  has a top planar hole  56  and a top planar end  62  with the protrusion  64  that mates with the opening  14  of the bottom half clamp  10 .  
         [0033]     The preferred embodiment of the present invention provides a device that includes a hinge, which allows for repeated use. This device is formed using two half clamps where the end of the first half clamp is slotted into the opening of the end of the second half of the clamp and subsequently enclosing the wires, or other suitable material. This aspect of the invention permits the clamp to be affixed around the wires or ducts and locked into place, without the use of any tools.  
         [0034]     This universal clamp responds to a need for a cost effective, easy to install replacement to the standard series of clamps available today. This clamp is ergonomically efficient in that it can be installed with one hand without tools. This ability to install this clamp using just one hand greatly reduces the risk of injury and makes installation time efficient. The use of the hinge allows the clamp to be opened and locked in place repeatedly without metal fatigue or cushion deformation. Permissive use subsequently lowers the cost of replacement parts and the costs associated with installation of the replacement parts. The ability to reuse this device also prevents the metal bands from failing due to fatigue. This clamp can be used to replace standard loop clamps in any type of installation and application.  
         [0035]     The universal loop clamp is designed to aid in the assembly of clamped components by holding itself closed and in place during installation. The clamp provides for installation of several clamps at one time at a single attachment point and is well suited for rapid clamp assembly and improved stacking methods for fluid lines, wire bundles, power feeder cables and fire detection lines. Easy installation not only increases productivity, it also allows for single-handed accessibility and easy clamping in hard-to-reach locations.  
         [0036]     The bottom half clamp  10  and top half clamp  40  represent the two metal bands of the clamp. The present invention is configured to mate the two clamps whereby the flanged end  32  is inserted into the top opening  48  of the top half clamp  40  to form a hinge and then engage the protrusion  64  of the top half clamp  40 , with the opening  14  of the bottom half clamp  10 , to close the clamp and lock it in place. The hinge then allows the clamp to pivot open and closed repeatedly, which prevents the metal bands from undergoing metal fatigue and later, failure.  
         [0037]     Once the two half clamps are mated to form the clamping assembly, the cushion housing  66  may be attached to the clamp. The clamp locks easily, whereby the protrusion  64  of the top half clamp is engaged with the opening  14  of the bottom half clamp. This engagement can be done easily, with one hand and requires no tools of any kind. The time required for locking the clamp is minimal.  
         [0038]     Unlocking the clamp is just as easy and quick. Pushing the top half clamp  40  inward away from the opening  14  quickly releases the top half clamp  40  from the bottom half clamp  10 . Also, wires, ducts or the like are easily removed from the clamp since the top half clamp opens widely without metal fatigue.  
         [0039]     Upon locking, the top planar hole  56  of the top half clamp  40  is aligned with the bottom planar hole  18  of the bottom half clamp  10 . It is through the top planar hole  56  and the bottom planar hole  18 , that a fastening device such as a screw, attaches the clamp to another object such as an air frame. In this manner, several clamps can be used at once and stacked on top of each other by fastening the holes of the individual clamps together. These universal clamps can also be rotated about the fastening means by turning the clamp.  
         [0040]     In a preferred embodiment, the present invention also incorporates a difference in the thickness between the top planar surface  58  of the top half clamp  40  and the bottom planar surface  12  of the bottom half clamp  10 . In particular, the top planar surface  58  is thicker than the bottom planar surface  12 . The difference in thickness provides for the top planar surface to be flush with the locking mechanism, allowing the clamps to be stackable. This difference in thickness also allows for multiple pay loads to be mounted at one location.  
         [0041]     The slot  26  of the bottom half clamp  10  and the slot  54  of the top half clamp  40  provide yet another benefit. These slots allow the clamp to be light yet still perform well. The cumulative effect of using numerous lighter clamps in aircraft or automotive applications lowers the weight considerably, resulting in lower total installed weight. This results in lower cost, as well as greater maneuverability. Thus, the universal clamp results in cost savings in that it is lightweight, requires no tools for installation, reduces the occurrence of injuries, can be used repeatedly, and does not experience metal fatigue or failure.  
         [0042]     Another embodiment of this invention includes inserting flanged end  32  of the bottom half clamp  10  into the top opening  48  of the top half clamp  40  and bringing the top half clamp around whereby the top planar surface  58  of the top half clamp  40  rests approximately parallel to the bottom planar surface  12  of the bottom half clamp  10 . This embodiment also includes inserting the protrusion  64  of the top half clamp  40  into the opening  14  of the bottom half clamp  10 , locking the universal clamp.  
         [0043]     Another embodiment of this invention may include the further step of affixing the universal clamp to another object such as an air frame by way of inserting a fastening means such as a screw through the top planar hole  56  of the top planar surface  58 , resting atop the bottom planar hole  18  of the bottom planar surface  12 . Yet another embodiment of the invention includes a system for fastening wires or ducts to another object, such as an air frame, whereby a top member mates with a bottom member at one end and a protrusion of the top member engages with an opening of the bottom member at the other end.  
         [0044]      FIG. 4  is a side view of the mated clamp assembly at the pivot point between the top and bottom clamp members according to an alternate embodiment of the present invention. This figure discloses that that the bottom half clamp  10  is looped or curved at one end  74  such that it can be mated with the top half clamp  40 . The looped section  76  is configured such that the top half clamp  40  is freely permitted to move about. The free movement of the looped section  76  enables the clamp to be opened and closed substantially free of interference at the pivot point.  
         [0045]     Referring to  FIG. 4 , the top half clamp  40  includes an opening (not shown) that enables the looped section  76  of the bottom half clamp  10  to pass through it. Once the looped section  76  passes through the opening, the bottom half clamp  10  and the top half clamp are pivotally mated.  
         [0046]     It is noted that in this alternate embodiment the looped section  76  is curved back towards bottom half clamp  10  such that an entry point  78  is created. It is through this entry point  78  that the top half clamp  40  is permitted to enter and engage the bottom half clamp  10  through the opening (not shown). The spacing, which is created between the looped section  70  and the bottom half clamp  10 , creates the entry point  78  is limited such that enables the top half clamp  40  through to engage the bottom half clamp  10  as well as prevent the top half clamp  40  from disengage from the bottom half clamp  10 .  
         [0047]     In this alternate embodiment, it is within the scope of this invention that the bottom half clamp and the top half clamp can be used interchangeable. For example, the top half clamp  40  can contain the looped section  76 .  
         [0048]     The many features and advantages of the invention are apparent from the detailed specification, and thus, it is intended by the appended claims to cover all such features and advantages of the invention which fall within the true spirit and scope of the invention. Further, since numerous modifications and variations will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation illustrated and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
