Description

Ejector latch assembly and system for fastening a panel within a frame

The present invention relates generally to fastening a panel within a housing, and in particular to an ejector mechanism for securing a printed circuit board within a card bay or cabinet.

In general, computing devices such as servers include a plurality of printed circuit boards (PCBs) mounted in racks, trays or tracks within a larger enclosure. The PCB is typically coupled to a plurality of electrical connectors for receiving power or for transmitting or receiving electrical signals. Therefore, the PCB must be consistently and securely positioned within the computing device to maintain a secure and reliable electrical connection.

Currently, a release mechanism known as an "ejector" has been used to insert or discharge a PCB into a desired slot. The ejector can be attached to the front of the PCB (or "panel") and mechanically operated to securely secure or release the PCB within the computing device. As the popularity of computing devices continues to grow, the number and variety of PCBs also increases. Therefore, improved systems and devices are needed to insert or discharge PCBs.

The illustrative systems and assemblies disclosed herein can be used to secure a panel within a frame. For example, the systems and assemblies can be used to insert a board into a frame and/or can be used to eject a board from a frame. As used herein, the term "plate" is intended to encompass any card, sheet or other flexible or rigid surface (planar or non-planar) having any desired size or shape. Moreover, as used herein, the term "frame" is intended to encompass any slot, frame, tray, track or other structure that can be secured or mated therein. The term "frame" may or may not encompass additional structural components associated with the slots, frames, trays, tracks in which the panels are secured, including associated chassis, housing, boxes or other related structural components.

The illustrative systems and assemblies disclosed herein may be used in particular in conjunction with a printed circuit board (PCB). The exemplary systems and assemblies can be designed to be attached to a panel of a PCB. Moreover, the exemplary systems and assemblies can be configured to attach to or otherwise operate with a computing device, such as a computer or server chassis, for insertion or ejection of a PCB. Suitable PCBs and computing devices that can be used in conjunction with the disclosed exemplary systems and assemblies include, for example, telecommunications equipment. Those of ordinary skill in the art will be aware of other suitable PCB or computing devices from the description herein. Although the exemplary systems and assemblies disclosed herein are described in principle with reference to a PCB, it should be understood that the present teachings are not limited thereto.

Referring now to the drawings, FIGS. 1A-3 illustrate an exemplary ejector latch assembly 100 for securing a panel within a frame in accordance with various aspects of the present teachings. Assembly 100 can be used to insert or eject a PCB (e.g., PCB 10) into or from a computing device (e.g., server 50). As shown in Figures 1A-1E, an assembly 100 can be provided on each side of the panel being removed from the frame. In summary, the assembly 100 includes a base 110, a handle 120, an engagement structure 140, a button 150, a first gear 160, and a second gear 170. Additional details of the assembly 100 are described below.

The base 110 is configured to be coupled to a board. The base 110 provides an attachment between the assembly 100 and a plate that will be secured by the assembly 100. As shown in FIG. 1A, the pedestal 110 can be coupled to the PCB 10. In detail, the pedestal 110 can be coupled to one of the panels of the PCB 10.

The base 110 can include one or more of a number of different components. In an exemplary embodiment, base 110 includes three separate components 110a, 110b, 110c, as shown in FIG. Each of these components can be configured to couple to the PCB 10, the server 50, or the remaining components of the assembly 100, as described below.

In this exemplary embodiment, base assembly 110a is configured to be coupled to PCB 10 via a screw hole 111, as shown in FIG. One or more screws or bolts may pass through the screw holes 111 to attach the base 110 to the panel of the PCB 10. In this embodiment, as shown in FIGS. 1A, 2, and 3, the base assembly 110a is additionally configured to be coupled to the server 50 via a hardware (possibly including a set screw 112). It may be desirable to use a set screw 112 (other than other fastening components) to provide additional fastening of the PCB 10 to the server 50, as will be discussed in more detail below. However, other suitable structures for coupling the base 110 to a plate or frame will be known to those skilled in the art in light of the description herein.

In this exemplary embodiment, base assembly 110b includes one or more openings for connection with additional components from assembly 100. As shown in FIGS. 2 and 3, the base assembly 110b also includes a screw hole 111 for coupling the base 110 to the PCB 10. As shown in FIG. 3, the base assembly 110b includes an engagement opening 113 that is positioned to engage the engagement structure 140, and a ramp 117 that is positioned adjacent the engagement opening. The function of the engagement opening 113 and the ramp 117 will be described in more detail below with reference to the operation of the assembly 100. Additionally, in this embodiment, the base assembly 110b includes a hinge opening 114 for receiving the hinge 115. As will be explained in more detail below, the base 110 effects relative rotation between the handle 120 and the base 110 via engagement of the hinge opening 114 with the hinge 115.

In this exemplary embodiment, the base assemblies 110a, 110b, 110c can be coupled to one another via a plurality of screws 118. The base assembly 110a, 110b, 110c further receives at least a portion of the torsion spring 116. As will be described in more detail below, the function of the torsion spring 116 is to bias the rotation of the handle 120 relative to the base 110.

The handle 120 is pivotally coupled to the base 110. The handle 120 enables a user to actuate the assembly 100 to insert or eject the panel into or out of the frame. As shown by the dashed line in FIG. 1C, the handle 120 can be pivoted or rotated from the closed position 121 to the open position 123 via the intermediate position 122.

The handle 120 is pivotally coupled to the base 110 via a hinge 115. A hinge 115 extends between the handle 120 and the base 110 and defines an axis of rotation (or pivot axis) for pivoting the handle 120 about.

Handle 120 includes an elongated portion 124, as shown in Figures 2 and 3. The elongated portion 124 is sized and configured to be grasped by a user of the assembly 100 during operation of the assembly 100. The elongated portion 124 extends along an axis that is generally orthogonal to the axis of rotation of the handle 120 defined by the hinge 115.

The handle 120 can also include a protrusion 125, as shown in Figures 1D and 3. The projection 125 is positioned to contact the frame during pivoting of the handle 120 from the closed position 121 to the open position 123. 1D and 1E illustrate the contact between the protrusion 125 and the servo 50. Contact between the projection 125 during pivoting of the handle 120 toward the open position 123 and the servo 50 causes the PCB 10 to be removed from the servo 50, as shown in Figures 1D and 1E. The projection 125 and the handle 120 thereby provide leverage to eject the PCB 10 from the server 50.

The handle 120 can be coupled to the housing 130. The housing 130 houses a plurality of operational components of the assembly 100, as will be described in greater detail below. In an exemplary embodiment, the handle 120 is integrally formed with the housing 130, as shown in Figures 2 and 3. However, those of ordinary skill in the art will appreciate that the handle 120 can be formed separately from the housing 130 and attached to the housing.

Housing 130 can include one or a plurality of different components. In an exemplary embodiment, housing 130 includes two separate components 130a and 130b, as shown in FIG. Each of these components can be configured to couple to the base 110, the handle 120, or the remaining components of the assembly 100, as will be described below.

In this exemplary embodiment, housing assembly 130a is integrally formed with handle 120, as shown in FIG. Additionally, the housing assembly 130a includes a hinge opening 131 for receiving the hinge 115. As shown in FIG. 3, the housing assembly 130a includes a spring cutout 132 that surrounds the hinge opening 131. The spring cutout 132 provides a bearing surface for the torsion spring 116 to enable the torsion spring 116 to bias the handle 120. In an exemplary embodiment, the torsion spring 116 abuts the spring cutout 132 to bias the handle 120 toward the open position 123. Moreover, the housing assembly 130a includes a generally open outer end 133 for receiving the button 150, as will be described below.

In this exemplary embodiment, the housing assembly 130a includes a gear shaft 134 for positioning and enabling one of the gears of the assembly 100 to be rotated, as will be described in greater detail below. Further, the housing assemblies 130a and 130b can be coupled to each other via one or more screws 135. As shown in FIG. 3, the screws 135 secure the housing assemblies 130a and 130b along the gear shaft 134. Additionally, the housing assembly 130a includes a pair of support walls 136 for supporting the biasing elements 151, as discussed below.

The meshing structure 140 is coupled to the handle 120. The engagement structure 140 engages one or more other structures to limit movement of the handle 120. In particular, the engagement structure 140 is movable between an engaged position and a disengaged position. In the engaged position, the engagement structure 140 prevents the handle 120 from pivoting relative to the base 110. In the disengaged position, the engagement structure 140 does not prevent the handle 120 from pivoting relative to the base 110.

The meshing structure 140 is coupled to the second gear 170. In an exemplary embodiment, the engagement structure 140 is a pin, as shown in FIG. The pin can be integrally formed with the second gear 170 as shown in FIG.

In an exemplary embodiment, the engagement structure 140 is positioned to engage the engagement opening 113 on the base 110. When the engagement structure 140 is in the engaged position, it is located in the engagement opening 113; conversely, when the engagement structure 140 is in the disengaged position, it exits from the engagement opening 113. The side walls of the engagement opening 113 thereby provide a surface against which the engagement structure 140 can be secured to prevent the handle 120 from pivoting relative to the base 110. For example, attempting to rotate the handle 120 from the closed position 121 to the open position 123 when the engagement structure 140 is in the engaged position will cause the engagement structure 140 to abut against the sidewall of the engagement opening 113, thereby preventing the handle 120 from pivoting.

Button 150 is operatively coupled to engagement structure 140. The button 150 enables the user to move the engagement structure 140 between the engaged and disengaged positions, thereby allowing the user to lock and unlock the pivotability of the handle 120. The button 150 is movable between an extended position and a depressed position. In particular, the user can press on the outer surface of the button 150 to move the button 150 from the extended position to the depressed position.

In an exemplary embodiment, as shown in FIG. 3, assembly 100 includes a biasing element 151 that biases button 150 in an extended position. The biasing element 151 can be, for example, a coil spring. A coil spring surrounds the post 152 formed on the underside of the button 150 to stabilize the movement of the button 150 or to control the orientation of the biasing element 151. In this embodiment, the biasing element 151 is received in the housing 130. In particular, coil springs can be placed between the support walls 136 to maintain spring alignment and reliability during repeated use.

The biasing element 151 and the post 152 together define a button axis along which the button 150 can move. As shown in FIG. 3, the button 150 is orthogonal to the elongated portion 124 of the handle 120 along the axis of extension along the axis of the moving button. The button axis is additionally orthogonal to the pivot axis of the handle 120 and extends between the pivot axis and the projection 125.

In a preferred embodiment, the button axis extends on one side of the pivot axis (i.e., the right side best depicted in Figure 4D), the side and the pivot axis having one of the elongated portions 124 positioned thereon The sides (ie, the left side in Figure 4D) are opposite.

As shown in FIGS. 1A, 2, and 3, the button 150 extends from the outer surface of the handle 120. As shown in FIG. 4B, the button 150 is positioned in line with the elongated portion 124 of the handle 120 such that a portion of the outer surface of the button 150 is positioned along an axis defined by the elongated portion 124. The position of the handle 120 and button 150 can desirably increase the comfort and ease of use of the assembly 100.

While the button 150 is illustrated in the drawings as having conventional button shapes and configurations, it should be understood that the term "button" as used herein is not limited thereto. As used herein, the term "button" is intended to encompass any physical structure that can be physically switched from one location to another, such as a key, lever, buckle, slider, knob, or other object that can cause an animal.

The first gear 160 is coupled to the button 150. The first gear 160 forms part of the operative connection between the button 150 and the engagement structure 140. In detail, when the button 150 is moved from the extended position to the depressed position, the first gear 160 moves by the first distance.

In an exemplary embodiment, the first gear 160 is a strip gear, as shown in FIG. In this embodiment, the button 150 is pressed against the gear 160 to move the gear in a straight line distance within the housing 130. The button 150 moves the first gear 160 in the same direction as the button axis. As shown in FIG. 3, the button 150 can be integrally formed with the first gear 160. Alternatively, the button can be separate from the first gear 160 and can abut the surface on the first gear 160, as will be discussed below.

The second gear 170 is coupled to the first gear 160 and coupled to the meshing structure 140 . Similar to the first gear 160, the second gear 170 also forms part of the operative connection between the button 150 and the engagement structure 140. In detail, when the first gear 160 is moved by the button 150 by the first distance, the second gear 170 is moved by the second distance. As will be understood by those of ordinary skill in the art, the second distance may be the same or different than the first distance, depending on the design of the first gear 160 and the second gear 170. Movement of the second gear 170 by the second distance causes the engagement structure 140 to move between the engaged and disengaged positions.

Although the first gear 160 and the second gear 170 can be in direct contact with each other, this direct contact is not necessary. In an exemplary embodiment, the second gear 170 is a strip gear similar to the first gear 160. In this embodiment, the assembly 100 further includes a third gear 180 in the form of a pinion positioned between the first gear 160 and the second gear 170. In this embodiment, movement of the first gear 160 toward the base 110 causes a corresponding movement of the second gear 170 away from the base 110. Therefore, this causes the engagement structure 140 to move away from the engagement opening 113 of the base 110.

One exemplary operation of the assembly 100 will now be described below with reference to Figures 4A-7D. These figures show the operation of draining (or removing) a board (e.g., PCB 10) from a frame (e.g., server 50). It will be understood that performing these steps conversely will cause the panel to be introduced (or inserted) into the frame. 4A-4D show the assembly 100 in a first operational step before the user takes any action. In this step, the plate is fully inserted into the frame and the handle 120 is in the closed position 121 as shown in Figure 4A. The button 150 is biased by the biasing member 151 to be in the extended position, as shown in Figures 4C and 4D. This bias is transmitted to the meshing structure 140 via the gears 160, 170, 180. As a result, the engagement structure 140 is in the engaged position and is received in the engagement opening 113 of the base 110 as shown in Figure 4C. The engagement structure 140 thus prevents the handle 120 from rotating relative to the base 110.

5A-5D show the assembly 100 in a second operational step. In this step, the button 150 is pressed by the user and moved from the extended position to the depressed position, as shown in Fig. 5D. The button 150 moves the strip gear 160 inwardly a first distance, which causes the pinion 180 to rotate, thereby moving the strip gear 170 outward a second distance. As shown in FIG. 5C, due to the movement of the second gear 170, the engagement structure 140 is moved to the disengaged position in which the engagement structure 140 is withdrawn from the engagement opening 113.

Figures 6A-6D show the assembly 100 in a third operational step. In this step, the user has begun to rotate the handle 120 from the closed position 121 to the open position 123, and the handle is in the intermediate position 122, as shown in Figures 6A and 6D. During this rotation, the engagement structure 140 has moved away from alignment with the engagement opening 113 such that the two structures are unable to engage. As shown in this figure, the user has released the button 150 to allow the engagement structure 140 to move from the disengaged position, as shown in Figure 6C.

6A-6D also illustrate the assembly 100 in the fifth operational step (after the fourth operational step described below). In this step, the user has begun to rotate the handle 120 from the open position 123 described below to the closed position 121, and the handle is again in the intermediate position 122, as shown in Figures 6A and 6D. During this rotation, the engagement structure 140 is moving into alignment with the engagement opening 113 such that the two structures re-engage.

Alternatively, the contact between the engagement structure 140 and the ramp 117 moves the engagement structure 140 into alignment with the engagement opening 113. However, once the handle 120 reaches the closed position, the engagement structure 140 exits the ramp 117 and is aligned with the engagement opening 113 where the biasing element 241 biases the engagement structure 140 to engage it within the engagement opening 113. Location, as will be described in more detail below.

7A-7D show the assembly 100 in a fourth operational step. In this step, the user has completed rotating the handle 120 to the open position 123, as shown in Figures 7A and 7D. During this rotation, the projections 125 have contacted the surface of the frame (not shown). Contact between the projection 125 and the frame during rotation of the handle 120 causes the lever to move away from the frame, thereby exposing the physical ejection of the panel. After that, the user can pull the board out of the frame by grasping the sides of the board and pulling the handle 120.

8A-12D depict the operation of the illustrative assembly 200. The illustrative assembly 200 includes the same components as the assembly 100, except as set forth below. In the following description, the same element symbols are used to refer to the same components as the assembly 100, and new component symbols are used to refer to changed or new components.

As shown in FIG. 8C, in assembly 200, button 250 is a component that is separate from first gear 260. The first gear 260 abuts the lower surface of the button 250, but can be separated from the button 250 as will be described with reference to the operation of this embodiment. Additionally, this alternative embodiment includes a second biasing element 241, as shown in Figure 8C. The biasing element 241 biases the engagement structure 140 toward the engaged position.

8A-12D illustrate one operation of assembly 200 for removing a board (such as PCB 10) from a frame (such as server 50). Figures 8A-8D show the assembly 200 in a first operational step before the user takes any action. In this step, the plate is fully inserted into the frame and the handle 120 is in the closed position 121, as shown in Figure 8A. As shown in Figures 8C and 8D, the button 250 is biased in the extended position by the biasing member 151. Additionally, the engagement structure 140 is biased by the biasing member 241 in the engaged position and received within the engagement opening 113 of the base 110, as shown in Figure 8C. The engagement structure 140 thus prevents the handle 120 from rotating relative to the base 110.

Figures 9A-9D show the assembly 200 in a second operational step. In this step, the button 250 is pressed by the user and moved from the extended position to the depressed position, as shown in FIGS. 5A and 5D. When the button 250 is depressed, it abuts the strip gear 260, thereby moving the gear 260 a first distance inward, which causes the pinion 180 to rotate, thereby moving the strip gear 170 outward a second distance. As shown in FIG. 9C, as a result of the movement of the second gear 170, the biasing member 241 is compressed and the engagement structure 140 is moved to the disengaged position in which the engagement structure 140 is disengaged from the engagement opening 113.

10A-10D show the assembly 200 in a third operational step. In this step, the user has begun to rotate the handle 120 from the open position 123 to the closed position 121 with the handle in the intermediate position 122, as shown in Figures 10A and 10D. During this rotation, the engagement structure 140 is misaligned with the engagement opening 113 such that the two structures do not engage, but when further rotated to the closed position 121, the engagement structure 140 becomes aligned with the engagement opening 113.

Alternatively, the contact between the engagement structure 140 and the ramp 117 moves the engagement structure 140 into alignment with the engagement opening 113. However, once the handle 120 reaches the closed position, the engagement structure 140 exits the ramp 117 and is aligned with the engagement opening 113 where the biasing element 241 biases the engagement structure 140 to be in the engaged position within the engagement opening 113. , as will be described in more detail below.

11A-11D show the assembly 200 in a fourth operational step. In this step, the user has rotated the handle 120 into the open position 123, as shown in Figures 11A and 11D. During this rotation, the projections 125 have contacted the surface of the frame (not shown). Contact between the projection 125 and the frame during rotation of the handle 120 causes the lever to move away from the frame, thereby exposing the physical ejection of the panel. After that, the user can pull the board out of the frame by grasping the sides of the board and pulling the handle 120.

12A-12D show illustrative operations for inserting a board (eg, PCB 10) into a frame (eg, server 50). While this step is illustrated for assembly 200, it should be understood that substantially the same operation is performed during insertion of the board of assembly 100. 12A through 12D illustrate another rotational sequence, and are otherwise similar to the positions illustrated in Figures 10A through 10D.

In this step, the user rotates the handle 120 from the open position 123 to the closed position 121. During this rotation, the engagement structure 140 is biased by the biasing element 241 to be in the engaged position. Alternatively, for the assembly 100, if the user has released the button 150, the engagement structure 140 can be in the extended position. During rotation of the handle 120, the engagement structure 140 contacts the ramp 117 as shown in Figure 12C. As the rotation of the handle 120 continues, the ramp 117 moves the engagement structure 140 from the engaged position to the disengaged position. Once the handle 120 reaches the closed position, the engagement structure 140 exits the ramp 117 and is aligned with the engagement opening 113 where the biasing element 241 biases the engagement structure 140 to be in the engaged position within the engagement opening 113.

As shown in Figure 12C, the button is separated from the gear assembly such that the button operates independently of the gear. In other words, any upward biasing of the button (such as applied by a spring) will not bias the engagement structure 140 downward. This thus allows the movement of the button to be independent of the engagement structure 140. However, such structures may include additional spring assemblies (as compared to assembly 100) as appropriate, and may include additional button assembly assemblies (as compared to assembly 100) as appropriate. These additional components and associated tool inventory allow for independent movement as between the button and the engagement structure 140.

An exemplary electronic switch operation of assembly 100 will now be described below with reference to Figures 13A-16B. These figures show the electronic switch assembly 190 utilized as appropriate in the assembly 100. In an exemplary embodiment, the switch 190 is configured such that when the handle 120 is in the closed position 121, the opening and closing are closed. When the handle 120 is moved to the open position 123, the switch 190 is opened.

The electrical coupling to switch 190 may depend on the function of the board being inserted into the frame. For example, switch 190 can be used to open or close a light, such as an LED light, to indicate that the handle is in an open or closed position. Additionally, a switch 190 can be used to control the power to the board being inserted.

For example, switch 190 can be used to prevent removal of the board when the system is powered up, or to cut power to the board when the board is discharged. Conversely, the switch 190 can be used to ensure that the board is properly inserted and locked in place within the frame before connecting power to the board. In other words, the closure of the handle 120 can cause the switch 190 to close, and thus allow transmission of signals suitable to activate the system and power the system for operation.

The steps of operation of switch 190 are illustrated in Figures 13A-16B. These steps generally correspond to the same steps illustrated in Figures 4A through 7D, additional descriptions of which are provided below.

Figures 13A and 13B show the assembly 100 of the first step of the switching operation before the user takes any action. In this step, the panel is fully inserted into the frame and the handle 120 is in the closed position 121, as shown in Figure 13A. As explained above, in this position, the engagement structure 140 prevents the handle 120 from rotating relative to the base 110. Additionally, as shown in FIG. 13B, the switch 190 includes a latch 191 that is biased to rotate about the pin 193 in the switch 190 in a counterclockwise direction. When the handle 120 is in the closed position 121, the latch 191 is pushed against the bias and is held in the down position by the abutment surface 192 of the handle 120. In this embodiment, the displacement of the latch 191 to the down position causes the switch to be in an open state, which allows power to propagate to the board.

14A and 14B show the assembly 100 in a second step of the switching operation. In this step, the button 150 is pressed by the user and moved from the extended position to the depressed position. In this step, the components of switch 190 have no change or relative motion.

15A and 15B show the assembly 100 in a third step of the switching operation. In this step, the user has begun to rotate the handle 120 from the closed position 121 to the open position 123 with the handle in the intermediate position 122, as shown in Figure 15A. During this rotation, the abutment surface 192 moves upward and away from the latch 191. The latch 191 of the switch 190 is free to rotate in the counterclockwise direction to the up position. In this embodiment, rotation of the latch 191 to the up position causes the latch to be in a closed state that shuts off power to the board.

15A and 15B also illustrate the assembly 100 in the fifth step of the switching operation (after the fourth step described below). In this step, the user has begun to rotate the handle 120 from the open position 123 to the closed position 121 with the handle in the intermediate position 122, as shown in Figure 15A. After this rotation, the abutment surface 192 moves downward and toward the latch 191. This further rotation of the latch 191 to the downward position in contact with the abutment surface 192 places the switch in an open state, which can be used to introduce electrical power to the board.

16A and 16B show the assembly 100 in a fourth step of the switching operation. In this step, the user has completed rotating the handle 120 to the open position 123, as shown in Figure 16A. The user can pull the board out of the frame by grasping and pulling the handle 120 on both sides of the board. The board can be safely removed from the frame because before this step, the switch 190 is closed, thus removing power to the board.

17A-24E depict various components of assemblies 100 and 200. These figures are presented to provide additional detail regarding each of the illustrated components. Additional aspects of this creation are embodied in such detailed views of the components of assemblies 100 and 200.

25A and 25B show another exemplary ejector latch assembly 300 for securing a panel within a frame in accordance with aspects of the present invention. Assembly 300 can be used to insert or drain a PCB (e.g., PCB 10) into a computing device (e.g., server 50). Assembly 300 can be placed on each side of the panel being removed from the frame. The assembly 300 includes a base 310, a handle 320, an engagement structure 340, a button 350, a first gear 360, and a second gear 370. The components above assembly 300 may include the same features as the corresponding components of assemblies 100 and 200, except as set forth below.

The pedestal 310 is configured to couple to a board. The base 310 provides an attachment between the assembly 300 and a plate to be secured by the assembly 300. As shown in FIG. 25B, the susceptor 310 can be coupled to the PCB 10. In detail, the pedestal 310 can be coupled to the panel of the PCB 10. The pedestal 310 can be formed from one or more components as described above with respect to the susceptor 110.

The handle 320 is pivotally coupled to the base 310. The handle 320 enables a user to actuate the assembly 300 to insert or eject the panel into or out of the frame. The handle 320 can be pivoted or rotated from the closed position to the open position by an intermediate position.

The handle 320 is pivotally coupled to the base 310 via a hinge 315. A hinge 315 extends between the handle 320 and the base 310 and defines an axis of rotation (or pivot axis) for pivoting the handle 320 about.

Handle 320 includes an elongated portion 324 as shown in Figure 25A. The elongated portion 324 is sized and configured to be grasped by a user of the assembly 300 during operation of the assembly 300. The elongated portion 324 extends along an axis that is generally orthogonal to the axis of rotation of the handle 320 defined by the hinge 315.

The handle 320 can also include a tab 325 as shown in Figures 26A and 26B. The tab 325 is positioned to contact the frame during pivoting of the handle 320 from the closed position to the open position. Contact between the protrusion 325 and the frame during pivoting of the handle 320 toward the open position causes the PCB 10 to move out of the servo 50. The tab 325 and the handle 320 thereby provide leverage to eject the PCB 10 from the servo.

The handle 320 can be coupled to and/or merge the housing 330. Housing 330 houses a number of operational components of assembly 300, as will be described in greater detail below. In an exemplary embodiment, the handle 320 is integrally formed with the housing 330 as shown in Figure 25A. However, it will be understood by those of ordinary skill in the art that the handle 320 can be formed separately from the housing 330 and attached to the housing.

In an exemplary embodiment, the housing 330 includes a spring cut-out to provide a bearing surface for the torsion spring 316 to enable the torsion spring 316 to bias the handle 320. The torsion spring 316 abuts the spring cutout in the housing 330 to bias the handle 320 toward the open position.

The engagement structure 340 is coupled to the handle 320. Engagement structure 340 engages one or more other structures to limit movement of handle 320. In particular, the engagement structure 340 is movable between an engaged position and a disengaged position. In the engaged position, the engagement structure 340 prevents the handle 320 from pivoting relative to the base 310. In the disengaged position, the engagement structure 340 does not prevent the handle 320 from pivoting relative to the base 310.

The meshing structure 340 is coupled to the second gear 370. In an exemplary embodiment, the engagement structure 340 is a pin, as shown in Figure 26B. The pin may be integrally formed with the second gear 370 as shown in Fig. 26B.

In an exemplary embodiment, the engagement structure 340 is positioned to engage the engagement opening 313 on the base 310. As shown in Figure 26B, the housing 330 can further include a biasing element 344, such as a coil spring, for biasing the engagement structure 340 to engage the engagement opening 313. When the engagement structure 340 is in the engaged position, it is positioned within the engagement opening 313; conversely, when the engagement structure 340 is in the disengaged position, it exits from the engagement opening 313. The sidewall of the engagement opening 313 thereby provides a surface against which the engagement structure 340 can be configured to prevent the handle 320 from pivoting relative to the base 310. For example, attempting to rotate the handle 320 from the closed position to the open position when the engagement structure 340 is in the engaged position will cause the engagement structure 340 to abut the side wall of the engagement opening 313, thereby preventing the handle 320 from pivoting.

Button 350 is operatively coupled to engagement structure 340. The button 350 enables the user to move the engagement structure 340 between the engaged and disengaged positions, thereby allowing the user to lock and unlock the pivotability of the handle 320. The button 350 is movable between an extended position and a depressed position. In particular, the user can press on the outer surface of the button 350 to move the button 350 from the extended position to the depressed position. As shown in Figure 27B, the button 350 is moved between an extended position and a depressed position by rotation about a pivot point 353 located in the handle 320.

In an exemplary embodiment, assembly 300 includes a biasing element 351 that biases button 350 in an extended position, as shown in Figure 26B. The biasing element 351 can be, for example, a torsion spring. In this embodiment, the biasing element 351 is received within the handle 320 adjacent to the button 350.

The button 350 is resistant to the bias applied by the biasing element 351, moves away from the PCB 10 and moves into the handle 320. In other words, when the user grasps the handle 320, the button 350 can be actuated by the action of the pull trigger. As shown in FIG. 3, when the button 350 is actuated, the button moves along an elongated axis 324 that is generally orthogonal to the handle 320 in the direction of the axis of extension. This motion is also generally orthogonal to the pivot axis of the handle 320.

As shown in FIG. 25A, the button 350 is located on the inner side of the handle 320. As shown in FIG. 25A, the handle 320 can include a cutout 354 for accessing the button 350 such that the outer surface of the button 350 is positioned to approximately align with the inside of the handle 320. This position of the handle 320 and button 350 can desirably increase the comfort and ease of use of the assembly 300.

While the button 350 is illustrated as being accessible only in the small cutout 354 of the handle 320, it should be understood that the button 350 can cover a significant portion or all of the inside of the handle 320. As shown in FIG. 30, in accordance with another exemplary embodiment of the present creation, the button 350 can be accessed along a majority of the handle 320 outside of the end of the handle 320. Therefore, various configurations of the buttons can be considered together with the relevant adjustments of the components to which the buttons are coupled.

Referring back to FIG. 26B, for example, the first gear 360 is coupled to the button 350. The first gear 360 forms part of the operative connection between the button 350 and the engagement structure 340. In detail, when the button 350 is moved from the extended position to the depressed position, the first gear 360 moves by the first distance.

In an exemplary embodiment, the first gear 360 is a strip gear as shown in Figures 26B and 27B. In this embodiment, the button 350 is integrally formed with the first gear 360. Alternatively, the button can be separate from the first gear 360 and can abut the surface on the first gear 360.

The second gear 370 is coupled to the first gear 360 and coupled to the engagement structure 340 . Similar to the first gear 360, the second gear 370 also forms part of the operative connection between the button 350 and the engagement structure 340. In detail, when the first gear 360 is moved by the button 350 by the first distance, the second gear 370 is moved by the second distance. As will be understood by those of ordinary skill in the art, the second distance may be the same or different than the first distance, depending on the design of the first gear 360 and the second gear 370. Movement of the second gear 370 by the second distance causes the engagement structure 340 to move between the engaged and disengaged positions.

Although the first gear 360 and the second gear 370 can be in direct contact with each other, this direct contact is not necessary. In an exemplary embodiment, the second gear 370 is a strip gear similar to the first gear 360. In this embodiment, the assembly 300 further includes a third gear 380 in the form of a pinion positioned between the first gear 360 and the second gear 370. In this embodiment, pressing button 350 causes button 350 to rotate about pivot point 353 and first gear 360 moves toward PCB 10. Movement of the first gear 360 toward the base 310 causes the second gear 370 to move away from the base 310 accordingly. Therefore, this causes the engaging structure 340 to move away from the engaging opening 313 of the base 310.

It will be understood by those skilled in the art that assembly 300 can include additional or alternative components as would be understood by those of ordinary skill in the art. For example, assembly 300 can incorporate an electronic switch assembly such as switch 190 in the same manner as described above with respect to assembly 100.

An exemplary operation of assembly 300 will now be described below with reference to Figures 26A-29. These figures show the operation of removing a board, such as PCB 10, from a frame, such as server 50. Figures 26A and 26B show the assembly 300 in a first operational step before the user takes any action. In this step, the plate is fully inserted into the frame and the handle 320 is in the closed position, as shown in Figure 26A. The button 350 is biased by the biasing element 351 to be in the extended position. This bias is transmitted to the meshing structure 340 via gears 360, 370, 380. Similarly, biasing element 344 biases engagement structure 340 toward base 310. As a result of the bias applied by the biasing element 351 and/or the biasing element 344, the engagement structure 340 is in the engaged position and is received within the engagement opening 313 of the base 310, as shown in Figure 26A. The engagement structure 340 thus prevents the handle 320 from rotating relative to the base 310.

27A-27C show the assembly 300 in a second operational step. In this step, the button 350 is pressed by the user and moved from the extended position to the depressed position as shown in Fig. 27A. Pressing the button 350 causes the strip gear 360 to move inward a first distance, which causes the pinion 380 to rotate, such that rotation causes the strip gear 370 to move outward a second distance. As the second gear 370 moves, the engagement structure 340 moves to the disengaged position in which the engagement structure 340 exits from the engagement opening 313, as shown in Figure 27B. As the engagement structure 340 exits from the engagement opening 313, the torsion spring 316 freely rotates the handle 320 relative to the base 310 away from the closed position.

Figure 28 shows the assembly 300 in a third operational step. In this step, the user has begun to rotate the handle 320 from the closed position to the open position with the handle in the intermediate position. During this rotation, the engagement structure 340 has moved to no longer align with the engagement opening 313 such that the two structures are unable to engage. As shown in this figure, the user has released the button 350 to allow the engagement structure 340 to move from the disengaged position, as shown in FIG.

Figure 28 also illustrates the assembly 300 in a fifth operational step (after the fourth operational step described below). In this step, the user has begun to rotate the handle 320 from the open position described below to the closed position, and the handle is again in the intermediate position. During this rotation, the contact between the engagement structure 340 and the surface of the base 310 resists the bias from the biasing element 344 to move the engagement structure 340 into the housing 330. Then, once the handle 320 reaches the closed position, the engagement structure 340 exits the surface of the base 310 and is aligned with the engagement opening 313 where the biasing element 344 biases the engagement structure 340 to engage the engagement opening 313. The inner meshing position will be described in more detail below.

Figure 29 shows the assembly 300 in a fourth operational step. In this step, the user has finished rotating the handle 320 to the open position. During this rotation, the protrusion 325 has contacted the surface of the frame. Contact between the protrusion 325 and the frame during rotation of the handle 320 causes the lever to move away from the frame, thereby expelling the body of the starting plate. After that, the user can pull the board out of the frame by grasping and pulling the handle 30 on both sides of the board.

30 illustrates another exemplary ejector latch assembly 400 for securing a panel within a frame in accordance with aspects of the present invention. Assembly 400 is similar in operation to assembly 300. Assembly 400 includes a base 410, a handle 420, a button 450, a first gear 460, and a second gear 470. Components above assembly 400 may suitably include the same features as corresponding components of assemblies 100 and 200 and 300.

The formation, assembly, and operation of the assembly 300 will be apparent from the foregoing description and depiction of such components, as will be apparent to those skilled in the art.

Although the present invention has been illustrated and described herein with reference to specific embodiments, the present invention is not intended to be limited to the details shown. Instead, various modifications may be made in the details without departing from the scope of the invention.
