Abstract:
A control pod for a plug and cord assembly secures the electrical appliance to which the cord is attached and prevents insertion of the plug into a power outlet by having an upper section connected to a lower section by a hinge on one side and a lock oppositely disposed from the hinge.

Description:
This invention relates to a control pod for securing an electrical device and more particularly to a control pod for securing the plug of an electrical device. 
     BACKGROUND OF THE INVENTION 
     Danger caused by electricity to persons in the workplace is a difficult problem to overcome. Many federal regulations are provided in order to protect the worker in the workplace, from the dangers of electrical plugs. 
     One protective device provides for a locking of the plug to a machine, while the machine is being maintained or repaired. With the plug locked, the machine cannot be unintentionally activated. This reduces the risk to the maintenance man and avoids unintentional plugging in of the machine, which can result in a danger to the maintenance man. 
     For example, as the maintenance man leaves to go on lunch, another party unaware that the maintenance is being carried out can activate the machine and plug in the cord. If the maintenance man forgets to check the plug, danger occurs. If the plug is locked, there is no chance for mistake. 
     In many cases, it is desired to prevent use of electrically powered equipment by unauthorized or untrained personnel. Whether the equipment is a power tool, a computer or another type of device, securing the plug will prevent unauthorized use. An efficient device for securing the plug can prevent such improper use. 
     Getting away from the industrial arena and proceeding to the home front, locking of the plug also prohibits a child from using an electrical device. If the plug is locked, the child may not turn on the power tool, the television or any other device sought to be protected from unauthorized use. Thus, the plugging protection is even needed in the home. 
     While the plug is locked in a protective cover, it is desirable to support the plug therein. With the plug supported within the pod, flex at the cord and plug union is minimized. With the flex minimized, wear at that point is minimized, and will last much longer. However, the cord protection and plug support work against each other. It desirable to maximize the advantages of both, but such is difficult to do. 
     SUMMARY OF THE INVENTION 
     Among the many objectives of this invention is to provide a control pod for securing an electrical plug in order to prevent use of the device, to which the cord and plug provide power. 
     Another objective of this invention is to provide a control pod for securing an electrical plug in order to secure an appliance in the home. 
     Yet another objective of this invention is to provide a control pod for securing an electrical plug in order to provide safety during maintenance of a machine. 
     Still another objective of this invention is to provide a control pod for supporting an electrical plug. 
     Additionally, an objective of this invention is to provide a control pod for an electrical plug, which limits use of an appliance. 
     Also, an objective of this invention is to provide a lockable control pod for an electrical plug. 
     A further objective of this invention is to provide a control pod for an electrical plug with minimal effect on a plug cord joint. 
     A still further objective of this invention is to provide a control pod for an electrical plug in to prevent unauthorized use of equipment. 
     Yet, a further objective of this invention is to provide a control pod for an electrical plug in to prevent unauthorized use of equipment. 
     These and other objectives of the invention (which other objectives become clear by consideration of the specification, claims and drawings as a whole) are met by providing a control pod for a plug and cord assembly in order to secure the electrical appliance, the control pod having an upper section connected to a lower section by a hinge on one side and a lock oppositely disposed from the hinge.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The control pod of this invention has an upper section and a lower section. Within each section are two plastic lips designed to hold the cord in its proper position. The hinge and spring are designed to cooperate and to hold the two sections together on one side. As the device closes, the plug head is contained therein and a locking mechanism prohibits the unauthorized opening of the control pod and prevents unauthorized of the appliance, for which, the cord supplies power. 
     Clearly any appliance having a plug can be secured with this control. Whether the appliance is a power tool, a computer, a household appliance or and other plug using device, if the plug is locked in the control pod of this invention, any appliance using that plug may get power to run. 
     Any durable material may be used to make the control. If high security is needed, metal may be used. Even tool strength metal can be used. Durable high impact plastic can also be used. Generally, the material used is determined by the security sought. 
     The locking mechanism can be by combination lock or by key. The lips to hold the plug in position prevent damage to the plug. The rounded nature or hollow elliptical nature of the plug pod makes for easy handling and decoration. It is the lips, locking, and the hinge and spring that provide the most effectiveness. The outer shape of the pod can be any suitable shape. However, the elliptical shape is desired. 
     The hinge assembly may be positioned either completely within the plug support control pod, on the outside thereof or somewhere in between. If the hinge is positioned in the middle of the wall of the pod, the sections of the pod can open about 180 degrees. If the hinge is positioned on the outside of the control pod, it is possible that the sections of the pod to open 240 degrees. 
     On interiorly mounted hinge, a beveled hinge edge of each section of the control pod permits the opening of the pod efficiently to get the plug inside. Where the wider opening is not desired and the beveling does not detract from the strength of the pod, the beveled edge may be used. 
     Referring now to FIG. 1 and FIG. 2, the control pod 100 includes a lower section 122 and an upper section 142. Both lower section 122 and upper section 142 are elliptically shaped hollow hulls. 
     However, at the lower part of lower section 122 is a plug support 124. Plug support 124 includes first lower radiused brace 134 and second lower radiused brace 136. Therebetween to support cord 112 is a first arc 132 at the base of the lower section 122. This first arc 132 provides for the cord 112 while first lower radiused brace 134 and second lower radiused brace 136 support plug 112. The combination of first arc 132 with first lower brace 134 and second lower brace 136 provide for support of the plug assembly 108. 
     In FIG. 1 particularly, mounted in the lower section 122 is a key-lock assembly 150 with lock bolt 152 protruding therefrom. Lock assembly 150 cooperates with hinge assembly 170 to secure lower section 122 to upper section 142 and secure plug assembly 108 therein. 
     Within upper section 142 is a first upper brace 144 and a second upper brace 146. Upper arc 162 combines with lower arc 132 to receive cord 112. Plug 110 mounts on the combination of lower braces 134 and 136, and upper braces 144 and 146, by supporting plug 110, hence plug and cord assembly 108 within the control pod 100. 
     Upon locking, the key lock assembly 150 can cause the lock bolt 152 to contact lock latch plate 154 and secure the plug head therein. 
     Hinge assembly 170 is mounted in standard fashion to the lower section 122 and upper section 142. Hinge spring 172 provides for ease of opening the pod when the lock is released. Spring 172 may also be reversed to permit for ease of closing the control pod 100. 
     In FIG. 2, combination lock assembly 190 is depicted with latch holes 192. Lock bolts 194 are in the upper section 142. In this fashion, the cord assembly 108 may be locked in by key lock assembly 150 or by combination lock 190. 
     FIG. 3 shows cord 112 sticking out of closed control pod 100 and profile view of key locked assembly 150 for control pod 100. By the same token, a side view as in FIG. 4 shows the key locked assembly 150 with the cord 112 sticking out. Thus, the cord assembly 108 is shown as secured therein. 
     In FIG. 5, the hinge assembly 170 is positioned completely within the control pod 100. With the hinge assembly 170 is positioned within lower section 122 and an upper section 142, beveling must occur so that control pod 100 may be opened. This is accomplished by beveled hinge edge 220. More particularly, lower section 122 has a lower beveled edge 222 while upper section 142 has an upper beveled edge 224, both being adjacent to hinge assembly 170. Lower beveled edge 222 combines with upper beveled edge 224 to permit control pod 100 to move lower section 122 up to 120 degrees relative to upper section 142. This opening is more than enough for the insertion or removal of plug and cord assembly 108 (FIG. 1). 
     With FIG. 6, the control pod 100 has the hinge assembly 170 mounted on the outside of the control pod 100. If the hinge assembly 170 is positioned on the outside of the control pod 100, it is possible for the sections 122 and 142 of the pod 100 to open 240 degrees. 
     Continuing with FIG. 7, the control pod 100, of this invention, wherein the hinge assembly 170 has a mid mounting point 230 and is partially mounted on the outside of the control pod 100. The sections of the pod 100 can open about 180 degrees, as reflected in FIG. 1 and FIG. 2. 
     As can be seen from FIG. 1 and FIG. 2 the hinge assembly 170 is preferably centered at one end of the short elliptical axis 180 on an edge of lower section 122 and upper section 142. At the opposing end of the short elliptical axis 180 is situation either combination lock 160 or key lock assembly 150. Such positioning provides the most efficient control pod 100.
