Referring to
In the illustrated example, the apparatus for mounting and dismounting a modular split flap housing 100 includes a housing or support structure 102, a first extension or latch 112, a second extension or latch 114, a surface of the back plate 116, and a sliding member 122, also referred to herein as a user interface element. A housing 102 is mounted on the surface the back plate 116. In the illustrated example, the housing 102 is securely installed in a locked position (
Two extensions or latches (112, 114) are positioned on the surface of the back plate 116. In
The sliding member 122 is movable from a first unlocked position to a second unlocked position to a locked position. When the sliding member 122 is closed and the sliding member 122 is in the locked position, the housing 102 is secured to the surface of the backplate 116. The extensions or latches (112, 114) insert into respective openings and interface with and is secured to respective snaps in the housing 102. The extensions or latches (112, 114) protrude through openings on the back side of the housing 102 because of the influence of the rotor unit within the housing 102.
According to one aspect of one or more of the various embodiments described herein, the housing 102 is sized such that the frame will fit within a rack mount configuration. Standard rack-mount systems are well-known in the art and are available from a variety of vendors. Such rack-mount systems are typically used to house server and telecommunication equipment and cabling within the data center, and generally have a set horizontal distance between vertically-oriented rails to which equipment is mounted.
Although a particular number of module bays are shown, the various embodiments described herein are not limited to any particular number or combination of bays. Rather, any number and configuration of module bays may be used.
In the example embodiment, the housing 102 and the back plate 116 are substantially parallel one to the other, and substantially perpendicular to the extensions or latches (112, 114), the extensions or latches (112, 114) being substantially parallel one to the other. The back plate 116 is substantially I shaped and is adapted to allow the housing 102 to be fed to a space in front of the rack mount 118. The back plate 116 comprises the extensions or latches (112, 114), which are adapted to facilitate fastening the housing 102 thereto. The housing 102 comprises openings, which are adapted to facilitate fastening the rack mount 118 thereto.
The rack mount 118 is preferably of knock down construction; however, certain portions of the rack mount 118 may alternatively be of unitary construction. The rack mount 118 is capable of being assembled quickly and easily. The rack mount 118 may be of metal, such as aluminum or steel, thermoplastics, thermosetting polymers, rubber, or other suitable material or combination thereof. The rack mount 118 may be painted or left in an as-is condition.
The back plate 116, which is I shaped, comprises a substantially planar portion and the extensions or latches (112, 114) extending therefrom. The substantially planar portion is substantially centrally disposed in the back plate 116. The substantially planar portion comprises the extensions or latches (112, 114) extending therefrom, which are adapted to facilitate fastening the housing 102 thereto. The extensions or latches (112, 114) comprise substantially trapezoidal projections or hooks 124 for fastening the back plate 116 thereto the rear side of the housing 102. The position of the housing 102 is adjusted thereon the extensions or latches (112, 114), and the sliding member 122 is fastened thereto the front side of the housing 102. The sliding member 122 can be slid to the fastened position with finger pressure.
The sliding member 122 is movable between a lock position protruding inward in the horizontal depth direction of the sliding member 122 and a lock release position retracted outward in the horizontal depth direction. This moving direction is a direction orthogonal to the back plate 116 and the rack mount 118.
When the sliding member 122 is in the unlocked position, the rear side of the housing 102 moves towards the back plate 116 when the sliding member 122 moves rearward. When the sliding member 122 further moves rearward, the housing 102 is in contact with the back plate 116. Then, the extensions or latches (112, 114) move to the locked position against the urging force of the projections. The projections have such a rigidity that it does not deform inadvertently when the sliding member 112 is pushed. If the unlock position is formed by the sliding member 122, the extensions or latches (112, 114) can be pushed to the lock position.
When the sliding member 122 is in the locked position, the rear side of the housing 102 moves away from the back plate 116 when the sliding member 122 moves frontward. When the sliding member 122 further moves frontward, the housing 102 is detached from the back plate 116. The extensions or latches (112, 114) move to the unlocked position against the urging force of the projections. The projections have such a rigidity that it does not deform inadvertently when the sliding member 122 is pulled. If the locked position is formed by the sliding member 122, the extensions or latches (112, 114) can be pulled to the unlock position.

The straight state of this device as shown in
The contact rib 304 that forms the contact extend in the direction of the conductor track or in the direction of the extensions or latches (112, 114), so that the insertion required to introduce the extensions or latches (112, 114) into the housing 102 and the contact surface of the structure the force is kept relatively small. The contact rib 304 further acts as a guide when inserting the extensions or latches (112, 114). On the other hand, sufficient contact force or planar pressure can be achieved at the contact points. Thus, according to one or more of the various embodiments described herein, these two fundamentally conflicting requirements can be combined into one another.
According to an embodiment of the present application, the contact surface is flat and the contact rib 304 extends linearly along the longitudinal axis of the extensions or latches (112, 114). The rib 304 extends parallel to the contact surface plane in the tightening position. This achieves a large contact length along the longitudinal axis of the housing 102.
Alternatively, the contact surface can be convexly curved along the longitudinal axis of the housing 102 in the direction of the extension or latch 112. In this embodiment, preferably the radius of curvature may slightly penetrate the extension or latch 112 along the longitudinal axis of the housing 102 to which the contact rib 304 is tightened and over the length extended along the longitudinal axis. The edge of the contact rib 304 is configured with such an acute angle. However, depending on the application, it may be desirable that the contact length of the rib 304 be shortened by bending. In some cases, it may be advantageous to configure the contact surface in a spherical (two-dimensional convex) or saddle shape.
The number of contact ribs can preferably range from about 2 to about 8. Thereby, on the one hand, a sufficient contact force is obtained, and on the other hand, a sufficient frictional coupling against the housing 102 is obtained. However, in some cases, it is not excluded to provide at least two or three contact ribs.
The structure of apparatus of the various embodiments described herein is not limited to the above-mentioned example. The contact rib draws bore in and draws height in. The rib bar sectional dimension parameter is determined by the deployable ground plane device in space. According to concrete specifics, its development size can cover several millimeters to up to a hundred millimeters of bores and can be scaled to size even larger. Torsion spring type of drive of the various embodiments described herein also can adopt motor-driven according to concrete specifics and can also drive and control by trailing cable.

The first end 424 comprises a curved flange 430 for use as a user interface element extendable from the housing structure configured to be pulled or pushed by external force The curved flange 430 and a portion of the elongated section 426 are disposed within the housing structure.
When the sliding member 122 is in the first position, the curved flange 430 is withdrawn away from pressing on the surface of the rear wall of the surrounding structure, resulting in the first corresponding geometry of the bump 432 being mated with a first geometry of the structure, and further resulting in the second corresponding geometry of the structure being unmated from the bump 432.
When the sliding member 122 is in the second position, the curved flange 430 is pressed against a surface of the rear wall of the surrounding structure, resulting in the bump 432 being pressed against, and mated to the second corresponding geometry of the structure, and further resulting in the first corresponding geometry of the structure being unmated from the bump 432.
The sliding member 122 is suspended by and supported by a plurality of support members. Although one configuration of the sliding member 122 is illustrated, the various embodiments described herein may be used with any type or configuration. An elongated section 426 is specifically received in and/or secured in a receptacle of the structure. See
The sliding member 122 of the various embodiments described herein is adapted so that an operator located at the front side 518 of the display housing may pull a modular split flap housing to be removed from the front side 518 of the apparatus forwardly to a more ergonomically friendly position from a row of modules suspended by and contacting the two adjacent modules, named proximal and medial modules for purposes of this document, have been unloaded or removed. Thus, a person unloading the module from the front side 518 or proximal location of the container will not have to stretch or reach to the back of the module.
Similarly, a person loading the module from the front side 518 of the display housing need not stretch or reach to the back of the display housing to insert or load a module into the structure. The loader of the module may push the sliding member 122 already loaded with rows of modules rearwardly and load additional modules in a more ergonomically friendly position or manner. For example, after a module is loaded, the sliding member 122 is pushed rearwardly to enable the bump 432 to lock. Thus, the various embodiments described herein allow modules to be more efficiently and safely removed from these containers or inserted therein without unnecessary stress or strain on the unloader or loader.
Moreover, because the sliding member 122 is located at or near the top of the module, modules may be easily accessed. In other words, the sliding member 122 keeps the product in an optimum location for removal by an unloader or insertion by a loader.
Similarly, modules may be easily and quickly loaded into a reusable and returnable display housing using the one or more embodiments of the various embodiments described herein. A loader first loads a module so that the module is suspended between opposing modules, the first module being located in a distal position and the module being located in a medial position. Once a row of modules has been suspended along with the distal and medial modules, the distal and medial modules are fixed so that another row of modules may be loaded into the display housing. If the display housing contains additional rows of modules, the process continues until all modules of the display housing have been loaded.
The sliding member 122 may constitute metal, such as aluminum or steel, thermoplastics, thermosetting polymers, rubber, or other suitable material or combination thereof.
The tab projection forming the extensions or latches (112, 114) are elongated with an enlarged head at its distal end which reversibly snaps into the corresponding tabs or snaps (502, 504). The tabs or snaps (502, 504) are preferably an injection molded part constructed out of acrylonitrile-butadiene-styrene “ABS”, Acetal, Acrylic or Nylon. However, depending on the intended use, materials such as polycarbonate, polypropylene or polyurethane may be substituted. The alignment tabs or snaps (502, 504) prohibit the type of movement common to latch panels which are connected via an extruded latch which mount together via a slide-in function. Additionally, as shown in
The enlarged head formed on the extensions or latches (112, 114) is shown mated firmly within the tabs or snaps (502, 504), by constructing the catch out of a material with sufficient lubricity, flexibility and/or memory, the enlarged head may be withdrawn or snapped-out of the tabs or snaps (502, 504) by displacing the housing 102 which can snap-back, undamaged, upon withdrawal. Sufficiently flexible extensions or latches (112, 114) also places less stress on the enlarged head of latches (112, 114) thereby minimizing the risk of neck damage during attachment or detachment of panels.
The first extension or latch 112 comprises a raised element with a ramped end portion 516 that facilitates sliding of the sliding member 122 between the first position and the second position, via the first ramped end portion 516 making initial ramped contact with the second end 428 of the sliding member 122 during sliding.
In the first unlocked position in
In the first unlocked position, the housing 102 is configured to slide free from the surface of the back plate at an angle with respect to an orthogonal direction from the surface of the back plate.
In the second locked position in
A component of the housing 102 is an electrical connection and a data connection is established between a component of the back plate and of the housing. In response to disengagement of the electrical connection and the data connection from the component of the back plate, the disengagement can be detected and can result in a transmission of an alert message to a user device.
The rotor unit 506 is disposed within the wheel 508. The rotor unit 506 is operable to spin the wheel 508 by different fixed amounts of angular rotation respectively corresponding to a split flap 510 of the group of split flaps.
Referring to
The mating elements for the extensions or latches (112, 114), e.g., the tabs or snaps (502, 504), are accessible via a first opening 606 and a second opening 608, respectively, of the housing 102, wherein the first mating element and the second mating element are configured to receive a first extension or latch 112 from a mounting rack 118 and a second extension or latch 114 from the mounting rack 118, respectively, wherein the first extension or latch 112 has a first geometry configured to match a first corresponding geometry of the first tab or snap 502, and wherein the second latch 114 has a second geometry configured to match a second corresponding geometry of the second tab or snap 504.
In the first position, the extensions or latches (112, 114) are withdrawn away from the housing 102, resulting in the first corresponding geometry of the first extension or latch 112 being unmated from the first geometry of the first tab or snap 502, and further resulting in the second corresponding geometry of the second extension or latch 114 being unmated from the second geometry of the second tab or snap 504.
The sliding member 122 extends externally from the front side 518 of the housing 102 in a direction from the rear side 514 of the housing to the front side 518 of the housing.
Referring to
By configuring as above, it is seen that a loader or unloader can manipulate the apparatus to detach the housing 102 from the rack mount 118 when the module is not in use, for example, inoperative. At this time, the rear side 514 of the housing 102 is exposed. Next, insert one end of the housing 102 comprising the cavities (702, 704) and the input/output (I/O) ports 706 into the rack mount 118 with the extensions or latches (112, 114) already being aligned to the I/O ports 706 between the extensions or latches (112, 114). Once the extensions or latches (112, 114) are firmly inserted into the rack mount 118, the module is able to operate.
In brief, a characteristic of one or more embodiments of the various embodiments described herein is the exchangeability of the modules with a replacement module. Also, the plurality of I/O ports 706 of different functions are provided at the rear side 514 of the housing 102 with the extensions or latches (112, 114) being already aligned to the I/O ports 706. By configuring as above, it is possible of inserting housing 102 into the rack mount 118 due to the removal of an inoperative module from the rack mount 118. The module is then able to communicate with the system. This eliminates the tedious, repeated process of detaching fasteners from the housing 102. Moreover, an exchangeability of the modules and a simple operation are carried out by the invention. In addition, the invention has the benefits of simple construction, no interference between two mechanisms, and being ergonomic without the disadvantages of conventional systems.
As shown in
In addition, with the above construction, the sliding member 122 typically can be easily removed and installed onto the drawer. Specifically, the bottom of the drawer, which sits on top of the support members 800, drags across the top of the support members as the sliding member 122 is locked and unlocked. The end of the sliding member 122, comprising a curved flange 430, comes into minimal contact with the housing 102. Since there is less friction between the sliding member and the support members, it takes less effort to remove and install the drawer onto the drawer member.
For the above-mentioned embodiments, the sliding member may be made of metal, and may be fabricated by an extrusion process or a roll form process, among others.
