形成悬臂式冰箱搁架的一体式框架的方法
Method of forming a one-piece frame for a cantilevered refrigerator shelf
US-7401489-B2用于制造冰箱悬臂搁架的一体式框架。
专利摘要
一种用于冰箱搁架的一体式框架由平面坯料制成，该坯料具有从中心横梁成角度延伸的第一和第二侧构件。侧构件沿位于第一和第二侧构件与横梁之间的弯曲区折叠，使得一旦折叠，第一和第二侧构件从横梁向外延伸，形成三边框架。此时，第一和第二侧构件的边缘部分沿附加弯曲区折叠以形成上凸缘。优选地，横梁的上边缘部分沿又一个弯曲区折叠以形成钩元件。钩元件设计成与冷藏室中设置的搁架支撑构件接合，使得搁架框架以悬臂方式支撑。
Original abstractA one-piece frame for a refrigerator shelf is produced from a planar blank having first and second side members that extend at an angle from a central cross member. The side members are folded along bend zones located between each of the first and second side members and the cross member such that, once folded, the first and second side members extend outward from the cross member forming a three-sided frame. At this point, edge portions of the first and second side members are folded along additional bend zones to form upper flanges. Preferably, an upper edge portion of the cross member is folded along still another bend zone to form a hook element. The hook element is designed to engage with a shelf support member provided in the refrigerated compartment such that the shelf frame is supported in a cantilevered manner.
