Stowage closet side 100a illustrates articulating shelf system 120a being in a lowered, horizontal position (e.g., the x-axis), as also depicted in
Each end of rod 124 further includes an end cap 140. Each end cap 140 includes a flange 141 and plunger 142. Plunger 142 is configured to extend from end cap 140. Flange 141 may be used for manual retraction of end cap 140. End cap 140, including plunger 142, may be biased in the extended position (e.g., the z-axis) by a mechanism located within end cap 140. The mechanism may be a mechanical spring, an electro-mechanical solenoid, a rubber gromet, among others. Receivers 144 are positioned in the walls of stowage closet 100 (e.g., backside of front panel 102 and backside of back panel 106) and are configured to receive plunger 142. Receivers 144 may be a cup, an indent, a grommet, or other mechanism configured to received and secure plungers 142. A first pair of receivers 144, specifically lower receivers 144a, are positioned to receive plungers 142 when articulating shelf system 120 is in a lowered position and a second pair of receivers 144, specifically upper receivers 144b, are positioned to receive plungers 142 when articulating shelf system 120 is in a raised position. This allows shelf 122 to transition from a locked lowered position, as illustrated in
Shelf 122 includes a first portion 122a and a second portion 122b that are connected by a hinge 148 and in contact with shelf support 146. Shelf 122 may be made from wood, plastic, metal, and/or honeycomb material, among others. In various embodiments, a support recess 147 may be formed in first portion 122a and second portion 122b to make better use of the space with stowage closet 100. Hinge 148 forms a joint between first portion 122a and second portion 122b allowing shelf 122 to articulate, or bend. A second hinge 150 connects the second portion 122b to a vertical support 152, extending in the y-axis, allowing the second portion 122b to rotate from a horizontal position to a vertical position.
When articulating shelf system 120 is in the lowered position, as illustrated in
Raising articulating shelf system 120 includes depressing end caps 140 one either side of rod 124 to release plungers 142 from lower receivers 144a. Depressing end caps 140 may be done manually, by pressing a portion of a hand against flange 141 and pulling end caps 140, including plungers 142, toward each other. In various embodiments, rod 124 may include a button, or other mechanism, to depress end caps 140 and/or plungers 142. In various embodiments, movement of rod 124 may cause end caps 140 and/or plungers 142 to depress, thereby releasing them from receivers 144.
After depressing end caps 140, including plungers 142, rod 124, as an example, is lifted upward vertically (e.g., along the y-axis) causing shelf 122 to rotate about hinge 150. While rod 124 is used for description and illustrative purposed, other portions of shelf 122 may be lifted to achieve the same result. At the same time, or separately, rod 124 is pushed backward into the stowage closet 100 (e.g., along the x-axis), causing shelf 122 to articulate about hinge 148. This articulation allows first portion 122a and second portion 122b to rotate with respect to each other about hinge 148. End caps 140, including plungers 142, remain depressed through this motion as they are held in place by sidewalls of stowage closet 100. In various embodiments, end caps 140 may remain depressed in response to a button being pressed.
Shelf 122, specifically rod 124, is maneuvered into position over upper receivers 144b. Once rod 124, and more specifically end caps 140, are located over upper receivers 144b, end cap 140 and plungers 142 extend and lock articulating shelf system 120 into the raised position. In various embodiments, end caps 140 may extend in response to a button being released.
When articulating shelf system 120 is in the raised position, second portion 122b is parallel with vertical support 152 in the y-axis. First portion 122a is rotated with respect to second portion 122b, forming an angle α between first portion 122a and second portion 122b when plungers 142 are locked into upper receivers 144b. In various embodiments, angle α may be about 90° to about 120°, and more specifically, angle α may be about 100° to about 110°. Angle α may be determined to allow sufficient room within stowage closet 100 for hangers (e.g., clothing 132) to be used with rod 124 and allow doors 108 to be closed.
Moving articulating shelf system 120 from the raised position to the lowered position is accomplished by reversing the steps of raising articulating shelf system 120 described above. End caps 140 are depressed to release plungers 142 from upper receivers 144b in a similar manner to that described above. Rod 124, for example, is pulled out of stowage closet 100 (e.g., along the x-axis) and downward (e.g., along the y-axis). This motion causes first portion 122a and second portion 122b to rotate about hinge 148 and become aligned with one another. This alignment may occur prior to achieving the horizontal position (e.g., along the x-axis). Second portion 122b rotates about hinge 150 as it lowers from the vertical position to the horizontal position. Plungers 142 then extend in lower receivers 144a when end caps 140 are located over lower receivers 144a.
Support rails 126 are affixed to interior walls of stowage closet 100 (e.g., backside of front panel 102 and back panel 106). In various embodiments, support rails 126 are further affixed to vertical support 152. As depicted in
