Shockrack case
An equipment case comprising a body and a door includes a compound hinge system connecting the door and the body which allows the door to rotate 270 degrees relative to the body. The compound hinge system has a hinge and a plurality of pins which engage the body or the door. The door can be removed by lifting on the door such that the pins are disengaged from the body. The door of the equipment case can be secured to the body by one or more latch systems. The equipment case may further comprise integrated platforms molded into the corners of an interior chamber of the case. The platforms comprise inserts which are configured to engage a shock absorber or frame.

The present invention relates to cases, such as rigid cases for transporting and/or storing products such as electronics and musical equipment. In particular, the invention relates to a case with a compound hinge system that allows the door to be removed entirely or to swing out and completely around to lie flat against the side of the case. The invention also relates to molded platforms integrated into the interior of the case having inserts that are adapted to engage a support frame or shockrack frame system.
BACKGROUND OF THE INVENTIONDurable cases for electronics, musical equipment and other equipment including a support frame or shockrack frame are well known in the art. Current cases require a user to detach multiple latches, usually about eight latches, in order to open and/or remove the one or more doors. This results in a large amount of time being spent to access the contents of the case. When two or more cases are stacked on top of each other, the latches may be inaccessible making displacement of the door impossible. In addition, for systems in which the door is secured by a hinge, the door is unable to swing entirely out of the way. This results in the door interfering with access to the contents of the case and prevents a user from placing cases in close proximity to each other. Accordingly, a lockable case that includes a compound hinge system which reduces the number of latches necessary to open and/or remove the door of the case would be considered useful. In addition, a hinge that allows the door of the case to swing entirely out of the way would be considered useful.
Current support frames and shockrack frames are secured to the case by a metal frame platform which adds additional weight to the case. The cost of production of the case is increased in such systems because of the need to manufacture the metal platforms. In addition, attaching the frame to the metal platform may be cumbersome and require many steps. Accordingly, a case which includes molded platforms integrated into the interior of the case to facilitate use of a frame system and reduce the weight and cost of the case would be considered useful.
SUMMARY OF THE INVENTIONThe present invention is directed to a compound hinge system and integrated platform molding embodied in a relatively rigid case. The case comprises a body and a door which are removably coupled by one or more latches and one or more compound hinge systems. The compound hinge system comprises a hinge and a plurality of pins which connect the hinge to the door or body of the case. The compound hinge system allows the door to swing within a range of about 270 degrees such that the door of the case may rest against a side wall of the case. In addition, the door may be easily removed by a user by lifting up on the door and/or hinge when the door is open. This results in displacement of the pins which were inserted into the body of the case. The door can be reinstalled by lowering the pins into the openings disposed on the body of the case.
The interior chamber of the case comprises molded platforms having inserts integrated into the corners of the case which are configured to be connected with a support frame such as a shockrack frame system. Each molded platform includes one or more inserts adapted to receive a shock absorber or snubber. The shock absorber can be screwed into or otherwise attached to the molded platform inserts and then a shockrack frame can be attached to the shock absorber.
BRIEF DESCRIPTION OF THE DRAWINGS
The drawings illustrate the preferred embodiments of the invention. The drawings show the case with a specific shape and style, but persons of ordinary skill in the art will recognize that the case may take various shapes and styles without affecting the inventive concepts herein.
Turning now to the figures, the case 50 of the present invention comprises a door 100, a body 200, an interior chamber 205 and a compound hinge system 300 which connects the door 100 and the body 200 (
The case 50 may include one or more compound hinge systems 300 which removably and rotatably couple the one or more doors 100 to the body 200 of the case 50 (
The hinge 310 includes a middle region 312, a side region 314 and a pair of lateral extensions 316. The side region 314 includes a substantially straight vertical edge 315 which is positioned adjacent to the door 100 of the case 50. The lateral extensions 316 are disposed on the opposite side of the hinge 310 from the side region 314. The lateral extensions 316 are configured to be received within recesses 210 disposed in the body 200 of the case 50 as described further below. Preferably, the lateral extensions 316 extend approximately ½ to 1 inch beyond the middle edge 318 of the hinge 310. The total width WA of the hinge is typically in the range of about 2 to 5 inches.
The thickness or depth DA of the hinge may be uniform or non-uniform and generally ranges from approximately ¼ inch to about ¾ inch (
The compound hinge system 300 further comprises a plurality of pins 320, 330, 340 (
The hinge 310 also comprises two or more door pins 330, 340 disposed on the upper end 344 and lower end 334 of the side region 314 of the hinge 310. Preferably, both doorpins 330, 340 extend vertically with the upper door pin 340 extending upwardly and the lower door pin 330 extending downwardly (
The body 200 of the case 50 comprises two or more recessed portions 210 configured to receive the lateral extensions 316 of the hinge 310 (
The door 100 comprises one or more recessed portions 130 configured to receive the hinge 310 (
In a preferred embodiment the door 100 and body 200 comprise one or more complimentary latch systems 400 disposed on the side opposite the compound hinge 300 (
In a further embodiment, the door 100 may comprise means for securing the door 100 to the body 200 when the door 100 is in the full open position and lies flat against the side 204 of the case 50 as shown in
The interior chamber 205 of the case 50 comprises molded platforms 250 disposed at the each of the corners 260 of the case 50 (
The molded platform 250 reduces the amount of space necessary for the frame connection 500 as compared to current systems which require use of a metal platform. In addition, the molded-in format reduces the overall cost of the case 50 in comparison to use of a metal frame connector. The use of a molded plastic platform 250 rather than a metal frame connector also decreases the weight of the case 50 and facilitates use a support frame or shockrack frame 500 within the case 50.
The platform 250 may comprise two or more inserts 275 disposed at each of the eight corners 260 of the case 50 to allow the frame 500 configuration to be modified based on the needs of the user (
The shock absorber 600 used in conjunction with the platform 250 may be of any type known in the art. Preferably, the shock absorber 600 has a cylindrical body 620, a male threaded end 610 and a female threaded end 630. The male threaded end 610 is configured to be removably coupled with the insert 275 of the platform 250. The female threaded end 630 is configured to be removably coupled with a shockrack frame or other form of support frame 500.
The door 100 and body 200 of the case 50 may further comprise complementary grooves and/or protrusions 190, 290 configured to engage one another when the door 100 is closed against the body 200 (
In operation, a case 50 includes a body 200 and a door 100 with the door 100 being secured to the body 200 by one or more compound hinge systems 300 and one or more latch systems 400 (
If desired, the user may remove the door 100 and hinge 310 from the case 50 when the door 100 is open. The door 100 and hinge 310 may be removed by lifting on the door 100 and/or hinge 310 to displace the body pins 320 from the body pin openings 230 (
