Modular case and method of forming the same
View Patent ↗A modular case and method of forming the same, the case preferably formed from a plurality of panels, edge members and corner pieces having ribs. The panels, edge members and corner pieces are preferably connected to align the ribs, forming substantially continuous ribs capable of distributing forces over a large area of the modular case. The case is most preferably made of plastic, the connections preferably being hot-plate welds. Most preferably, the panels and edge members have a dual skin construction with internal ribs, proving for greater strength and allowing for superior structural properties including air-/water-tight integrity. Edge members are preferably formed with protuberances to allow for better base-to-lid and case-to-case engagement. Hardware attachments to the modular case can be advantageously made while distributing the force on attachment points and without compromising structural integrity.
1. A method for forming a modular case, the method comprising the steps of:
forming a master panel to have a skin and a plurality of panel reinforcing ribs extending outwardly therefrom;
forming a master edge member to have a skin and a plurality of edge member reinforcing ribs extending outwardly therefrom;
cutting the master panel into a plurality of case panels in accordance with a predetermined size of the modular case;
cutting the master edge member into a plurality of case edge members in accordance with the predetermined size of the modular case; and
mating the case panels and the case edge members to one another so as to define the modular case;
wherein each of the panel reinforcing rib is aligned end-to-end with a corresponding edge member reinforcing rib, such that a plurality of substantially continuous ribs are formed at the intersection of said case panels and said case edge members, said continuous ribs being capable of distributing a force acting on the modular case.
2. The method of claim 1 , wherein mating the case panels and the case edge members to one another so as to define the modular case includes hot-plate welding the case panels and the case edge members to one another.
3. The method of claim 1 , wherein forming the master panel to have the skin and the plurality of panel reinforcing ribs extending outwardly therefrom includes forming the master panel to have dual skins with the plurality of panel reinforcing ribs extending between the dual skins.
4. The method of claim 3 , further comprising the steps of:
removing a section of one of the dual skins of one of the case panels, the section sized in accordance with a size of a hardware assembly; and
attaching the hardware assembly in the section;
wherein the hardware assembly does not penetrate the other of the dual skins of one of the case panels.
5. The method of claim 1 , wherein forming the master edge member to have the skin and the plurality of edge member reinforcing ribs extending outwardly therefrom includes forming the master edge member to have dual skins with the plurality of edge member reinforcing ribs extending between the dual skins.
6. The method of claim 1 , further comprising the steps of:
forming a plurality of corner pieces to have a skin and a plurality of corner piece reinforcing ribs extending outwardly therefrom; and mating the corner pieces to the case edge members; wherein each of the corner piece reinforcing rib is are aligned end-to-end with a corresponding panel reinforcing rib, such that a plurality of substantially continuous ribs are formed at the intersection of said case panels and said case edge members, said continuous ribs being capable of distributing a force acting on the modular case.
