Abstract:
A container for TV cables and terminals with mating edges between the stationary body part and its hinged door to reduce the opportunity for forced illegal entry by apartment and condominium dwellers.

Description:
BACKGROUND OF THE INVENTION 
     Unlawful entry into containers is a serious problem. This is true of containers secured to buildings containing wire or cable connections for electrical or conmunication systems. Although not limited thereto, the subject invention is especially useful as a housing for TV cable equipment at the juncture of wires leading to individual living units and the master cable coming to the building. Breaking and entering into conventional boxes is not uncommon. Thieves do this to tap onto the master cable to avoid paying the usual service charges for TV service. Conventional boxes are relatively easy to break into. This is now corrected by the subject invention. 
     SUMMARY OF THE INVENTION 
     The subject invention is a container which is economical to make; easy to install and operate and which provides adequate resistance to criminals who might attempt to pry open the door of the unit. 
     The invention features a hinged door which is pushed upward and secured by the cam action of its lock when in the closed position. Such action brings flanges along the top and bottom edges of the door within matching grooves of the body of the container. Also the locking operation brings projections on one side of the door into matching recesses along one side of the container. Having a novel hinge on the remaining edge of juncture, the closed container is sealed. It avoids components that could serve as a bearing surface for tools used in prying.

     DESCRIPTION OF PREFERRED EMBODIMENT 
     Again referring to the drawing, wherein like numerals represent like parts throughout, the numeral 20 points to the entire unit. It is preferably made of 16 gauge galvanized sheet steel. Parts are riveted or spot welded together. Item 22 is the body portion. It is of rectangular shell configuration as illustrated. It has conventional &#34;knock-outs&#34; 30 in its bottom panel 50. This is for entry of conduits or cable 32 when used as a junction box. Vent louvers 34 may be provided on the side panels as shown. The top panel 48 may have conventional &#34;knock-out&#34; 60 to create orificies for wires. 
     Novel features reside in the outer edge of the top, bottom and one side of the body portion. Such edges are provided with recessed members suitable for accepting mating portions on the door. This is to thwart attempts to wedge a tool between the body portion and the abutting door. 
     Thus integral with, and as an extension of side 22, we have provided a flange with a plurality (preferably two) of L-shaped recesses 42. The end of the horizontal leg of each recess is open and the other leg extends vertically upward. 
     Attention is next invited to the bottom recessed member. It is preferably an inverted channel member 52 integral with and extended along the entire exposed edge. 
     Oppositely disposed to the bottom is top recessed member 58. It too is of U-shape channel configuration. One leg thereof is an extension of the outer edge of the top panel. It is beyond the lateral distance of the bottom extension whereby the transverse section of the portion is flush with the face of the door when the door is closed. 
     Turning now to the novel door, it features projections to snugly fit within the space of the body portion recesses. Thus projections 40 are mounted by their bases to an inwardly turned edge-section (unnumbered) along one side of door 24. They are essentially bosses or pins and are the same in number as recesses 42 in which they fit. 
     Next in order is bottom flange portion 44. It is formed as the up-turned outer edge of the horizontal bottom section (unnumbered) of the door panel. 
     Next, is top flange 46. It too is formed as the up-turned outer edge of the horizontal top section (unnumbered) of the door panel. As can be seen, the top horizontal section is more narrow than the parallel bottom horizontal section. This difference accommodates the difference in horizontal extension of the corresponding recessed portions with which the flanges mate. 
     For locking the door into engagement with the body portion, is securing means 26. Preferably, this securing means is a key 28 operated conventional lock mounted in the horizontal bottom section of the door midway along its length. The key rotates a shaft within the lock to which is affixed, at its opposite end, a bar or arm 36. FIGS. 7 through 9 of the drawings best show the engaging parts of the door, body, the lock and their alignments. 
     As a final novel contribution, the assembly has a novel hinge between the door and body. It is mounted along the side opposite that of the described projection and L-shape recess arrangement. Preferably it is a modified piano hinge. The common double-leaf 54 with pintle 56 features are retained. Unique space means is added between the leaves where they come together at the pintle. This space is substantially equal, in vertical dimension, to the distance the described projections move into the described recesses. This permits desired vertical movement of the door. 
     In use, the box is mounted on a building wall by screws or bolts through its back wall and with the projections, recesses and hinge spaces as illustrated. An incoming cable is permanently maintained through a fixed orifice. Outgoing multiple cables separately extend through orifices with suitable connections between the incoming and outgoing cables being provided within the container. To add or remove a cable the operator merely rotates the lock arm with a key. The arm slides off the horizontal surface of the bottom recess member and the entire door automatically drops due to the force of gravity. It drops far enough for the mating parts to clear each other and it stops because one hinge leaf again rests on the other leaf at the hinge pintle. Now the door may be swung open. To close and lock the door the process is reversed. The door is swung shut, then manually raised. Space is closed on one side of the hinge&#39;s leaves and equal space is opened on the lower other side. Projections and flanges fit into aligned recesses, the key is again turned and the arm resting on the bottom recess surface holds the door up in a sealed, tamper resistant position. 
     Skilled persons may make obvious changes without departing from the scope of the subjoined claims.
