DESC:TECHNICAL FIELD
[0001] The present disclosure relates to the field of electronic devices. In particular, the present disclosure pertains to a chassis assembly of an electronic appliance, specifically to an ejector for assembling a module to chassis of the electronic device.

BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Electronic devices/appliances typically incorporate number of modules, such as cards, fan trays etc., which are removably fitted on a chassis of the device. The modules are inserted and retained in position by locking using one or more ejectors that are locked after insertion of the module in its designated position, and unlocked when the module is to be removed or replaced from the chassis.
[0004] In a typical locking arrangement, the ejectors are pivotally fixed to the module for rotation after the module has been inserted, wherein the rotation of the ejectors engages the ejectors with a corresponding locking member on the chassis resulting in the ejectors retaining the module in the position. When the module is to be removed, the ejectors are rotated in an opposite direction to disengage the ejectors from the corresponding locking members so that the module may be removed from the inserted position.
[0005] Usually a large force is required to rotate the ejector to generate adequate locking force between the ejector and the corresponding locking member, both during locking and unlocking. Usually, the ejector is shaped so that in the locked position of the ejector, takes a position with minimum space requirement, such as adjacent to front side of to the module. However, this affects accessibility to the module. Any effort to modify the ejector, in the locked position of the ejector is positioned away from the front side of the module results in requirement of additional space. Besides, such a solution shall require unique ejectors for each of the modules in view of unique accessibility requirements of each module.
[0006] Therefore, there is a requirement of an improved ejector which, in locked position, does not affect accessibility to the corresponding module. It would be additionally beneficial if the modified ejector could be used for all the modules irrespective of their individual accessibility requirements on account different configurations.

[0038] Various terms are used herein. To the extent a term used in a claim is not defined, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.
[0039] Embodiments explained herein relates to a chassis assembly of an electronic appliance, specifically to an ejector for assembling a module to chassis of the electronic device.
[0040] In an aspect, present disclosure provides an ejector for a module in a device, the ejector comprising an actuator pivotally coupled to a chassis of the device to rotate about its pivot axis to move between a locked position and a unlocked position, wherein the rotation of the actuator at the locked position and the unlocked position facilitates locking and unlocking of the module respectively with the chassis of the device; and a handling member configured for detachable attachment to the actuator, where movement of the handling member in a first direction enables the actuator to move to the locked position and movement of the handling member in a second direction that is opposite to the first direction enables the actuator to move to the unlocked position.
[0041] In an aspect, the handling member comprises a guide pin, and the actuator comprises a recess.
[0042] In an aspect, the guide pin and the recess are cylindrically symmetric about an axis parallel to the pivot axis of the actuator.
[0043] In an aspect, the handling member is detachably attached through the guide pin and the recess such that when a force is applied on the handling member for moving the actuator about its pivot axis, the force is transferred to the actuator without any relative movement between the handling member and the actuator.
[0044] In an aspect, the handling member is configured to be attached and detached by moving it in direction along the pivot axis of the actuator.
[0045] In an aspect, the actuator comprises means for providing an additional locking to the actuator with the module in the locked position.
[0046] In an aspect, the handling member is configured to be detached from the actuator after the actuator has been locked with the additional locking.
[0047] In an embodiment, the handling member is configured to be attached to the actuator when the actuator has to be moved in an unlocked position.
[0048] In an aspect, the means includes a hole, which engages with a screw to provide the additional locking.
[0049] In an embodiment, the handling member includes a lever.
[0050] It is to be appreciated that while embodiments of the present disclosure have been explained with reference to a single handling member, it is possible to implement the inventive concept of the present disclosure with any numbers of handling members depending on requirement. For example, it is possible to have the concept implemented with a pair of handling members, and all such variations are well within the scope of the present disclosure without any limitations whatsoever.
[0051] FIGs. 1A and 1B illustrate exemplary perspective views of the proposed ejector assembly, in accordance with embodiments of the present disclosure. As shown, the disclosed ejector 100, also referred to as an ejector with a handling member, comprises an actuator 102 and a handling member 104, wherein the handling member 104 is configured for detachable attachment to the actuator 102. Thus, when a corresponding module is to be fitted in position, the handling member 104 may be attached with the actuator 102 to work as a handle to hold during insertion of the module (not shown here), as well as to provide adequate leverage when the actuator 102 is to be rotated to lock position, and after the module has been locked in position, the handling member 104 may be detached from the actuator 102. Likewise, when the module is to be unlocked and removed from the chassis, the handling member 104 may be attached with the actuator 102to provide adequate leverage for rotating the actuator 102 during unlocking, as well as to work as a handle to hold when the module is being withdrawn.
[0052] In an exemplary embodiment, the handling member can include, by way of an example but not as a limitation, a clip-on-lever (also referred to simply as lever and the two terms are used interchangeably hereinafter).
[0053] In an aspect, the handling member 104 may be detachably attached to the actuator 102 through a guide pin 110 configured at one end of the handling member 104 that gets attached to the actuator 102. The actuator 102 may include a corresponding recess 108. In an aspect, the guide pin 110 and the recess 108 may be profiled such that when a force is applied on the handling member 104 for moving the actuator 102 about its pivot axis, the force is transferred to the actuator 102 without any relative movement between the handling member 104 and the actuator 102. For this, the guide pin 110 and the recess 108 may have matching profiles that are cylindrically symmetric about an axis parallel to the pivot axis of the actuator 102. Thus, the handling member 104 can be attached and detached by moving it in direction along the pivot axis of the actuator 102.
[0054] In an aspect, the actuator 102 may also comprise means, such as a hole, to fix a screw, such as a screw 106, to prevent the actuator 102 from moving out of the locked position. The screw 106 may be screwed after the actuator 102 has been moved to the locked position, and may engage, after passing through the hole in the actuator 102, with a threaded hole in the chassis. Thus, the screw 106 provides an additional locking of the actuator 102 in the locked position.
[0055] In an aspect, after the actuator 102 has been locked by the screw 106, the handling member 104 may be removed from the actuator 102.
[0056] FIG. 2 illustrates an exemplary front view of a module fitted with the proposed ejectors showing clear accessibility to front side of the module in locked position of the ejectors, in accordance with embodiments of the present disclosure. As shown, after the module 202 has been inserted in the chassis and the actuators 102-1 and 102-2 (collectively referred to as 102) have been locked in the locked positions by screws 106-1 and 106-2 respectively (collectively referred to as 106), the handling member 104(not shown here) may be removed, leaving only the actuators 102 in position. As can be seen, front side of the module 202 is fully accessible without any hindrance.
[0057] FIGs. 3A to 3C illustrate exemplary perspective views showing different stages involved in insertion and locking of a module using the proposed ejectors, in accordance with embodiments of the present disclosure. As shown in FIG. 2A, the module 202 may be pushed into the chassis of a device and jacked in completely using the handling member 104 of the ejectors 100 as handles. The ejector particularly, the actuator of the ejector, is pivotally coupled to the chassis of the device to rotate about its pivot axis to move between a locked position and an unlocked position. The rotation of the actuator at the locked position and the unlocked position facilitates locking and unlocking of the module respectively with the chassis of the device.
[0058] Thereafter, the actuator of ejectors 100 may be rotated, using the handling member 104 thereof to provide the required leverage, till the actuators 102 engage with the locking members 204 fixed on the chassis. Once the ejectors 100 have been moved to the locked positions, the screws 106 may be fastened to provide additional locking of the actuators 102, as shown in FIG. 3B. With the actuators 102 firmly locked by the screws 106, the handling member 104 may be detached from the actuators, as shown in FIG. 3C.
[0059] Thus, it can be seen that the movement of the handling member in a first direction enables the actuator to move to the locked position and movement of the handling member in a second direction that is opposite to the first direction enables the actuator to move to the unlocked position.
[0060] Thus, the present disclosure provides an improved form of ejector with a detachable handling member such that the ejector can rotate easily while locking/unlocking around corresponding locking member.
[0061] As can be understood by those skilled in the art, the proposed ejector 100 may be used with different modules irrespective of their configuration as it overcomes any possibility of the ejector creating a hindrance in access to front side of the module. This can result in reduction in variety with corresponding cost benefits. Further, since the handling members 104 are detachable, a common set of handling members 104 may be used in combination with different actuators 102, thereby reducing cost of the ejector itself.
[0062] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
