Description:
BACKGROUND 
     Electronic components such as graphics cards, PCI express cards, etc. (herein “card(s)”) are often provided within a card slot in a system (e.g., desktop computing system). A card is placed within the card slot and typically is moved within the card slot to mate with connectors, e.g., to attach to a circuit board. Card slots that are not in use typically have a card insert, which is a placeholder that covers the card slot. 
     Card retainers act to keep the card in place. The card is secured by the retainer by virtue of the retainer abutting the end of the card, e.g., distal to the end of the card that connects to the circuit board. The card retainer is designed to secure the cards within the card slots, yet permit the cards to be removed, e.g., by a reverse operation of card insertion.

Thus, the following more detailed description of the example embodiments, as represented in the figures, is not intended to limit the scope of the embodiments, as claimed, but is merely representative of example embodiments. 
     Reference throughout this specification to “one embodiment” or “an embodiment” (or the like) means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearance of the phrases “in one embodiment” or “in an embodiment” or the like in various places throughout this specification are not necessarily all referring to the same embodiment. 
     Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments. One skilled in the relevant art will recognize, however, that the various embodiments can be practiced without one or more of the specific details, or with other methods, components, materials, et cetera. In other instances, well known structures, materials, or operations are not shown or described in detail to avoid obfuscation. 
     The illustrated example embodiments will be best understood by reference to the figures. The following description is intended only by way of example, and simply illustrates certain example embodiments. 
     An embodiment provides a single piece card retainer. The single piece card retainer may be used, for example, to secure a plurality of removable graphics cards within slots of a system housing. For example, the single piece card retainer may be used in connection with a personal computing device such as a desktop computer. 
       FIG. 1  depicts a block diagram of another example of device or system circuits, circuitry or components. The example depicted in  FIG. 1  may correspond to computing systems such as the THINKPAD series of personal computers sold by Lenovo (US) Inc. of Morrisville, N.C., or other devices. As is apparent from the description herein, embodiments may include other features or only some of the features of the example illustrated in  FIG. 1 . 
     The example of  FIG. 1  includes a so-called chipset  110  (a group of integrated circuits, or chips, that work together, chipsets) with an architecture that may vary depending on manufacturer (for example, INTEL, AMD, ARM, etc.). INTEL is a registered trademark of Intel Corporation in the United States and other countries. AMD is a registered trademark of Advanced Micro Devices, Inc. in the United States and other countries. ARM is an unregistered trademark of ARM Holdings plc in the United States and other countries. The architecture of the chipset  110  includes a core and memory control group  120  and an I/O controller hub  150  that exchanges information (for example, data, signals, commands, etc.) via a direct management interface (DMI)  142  or a link controller  144 . In  FIG. 1 , the DMI  142  is a chip-to-chip interface (sometimes referred to as being a link between a “northbridge” and a “southbridge”). The core and memory control group  120  include one or more processors  122  (for example, single or multi-core) and a memory controller hub  126  that exchange information via a front side bus (FSB)  124 ; noting that components of the group  120  may be integrated in a chip that supplants the conventional “northbridge” style architecture. One or more processors  122  comprise internal arithmetic units, registers, cache memory, busses, I/O ports, etc., as is well known in the art. 
     In  FIG. 1 , the memory controller hub  126  interfaces with memory  140  (for example, to provide support for a type of RAM that may be referred to as “system memory” or “memory”). The memory controller hub  126  further includes a low voltage differential signaling (LVDS) interface  132  for a display device  192  (for example, a CRT, a flat panel, touch screen, etc.). A block  138  includes some technologies that may be supported via the LVDS interface  132  (for example, serial digital video, HDMI/DVI, display port). The memory controller hub  126  also includes a PCI-express interface (PCI-E)  134  that may support discrete graphics  136 . 
     In  FIG. 1 , the I/O hub controller  150  includes a SATA interface  151  (for example, for HDDs, SDDs, etc.,  180 ), a PCI-E interface  152  (for example, for wireless connections  182 ), a USB interface  153  (for example, for devices  184  such as a digitizer, keyboard, mice, cameras, phones, microphones, storage, other connected devices, etc.), a network interface  154  (for example, LAN), a GPIO interface  155 , a LPC interface  170  (for ASICs  171 , a TPM  172 , a super I/O  173 , a firmware hub  174 , BIOS support  175  as well as various types of memory  176  such as ROM  177 , Flash  178 , and NVRAM  179 ), a power management interface  161 , a clock generator interface  162 , an audio interface  163  (for example, for speakers  194 ), a TCO interface  164 , a system management bus interface  165 , and SPI Flash  166 , which can include BIOS  168  and boot code  190 . The I/O hub controller  150  may include gigabit Ethernet support. 
     The system, upon power on, may be configured to execute boot code  190  for the BIOS  168 , as stored within the SPI Flash  166 , and thereafter processes data under the control of one or more operating systems and application software (for example, stored in system memory  140 ). An operating system may be stored in any of a variety of locations and accessed, for example, according to instructions of the BIOS  168 . As described herein, a device may include fewer or more features than shown in the system of  FIG. 1 . 
     Device circuitry, as for example outlined in  FIG. 1 , may be used in devices such as desktop computers that include discrete graphics  136  in the form of removable cards. In an embodiment, as illustrated in  FIG. 2 , a single piece card retainer is provided that attaches to the housing of the system in a rotatable fashion. 
     Specifically, as illustrated in the perspective view of  FIG. 2 , a single piece card retainer  200  includes a back surface  201  (obscured due to the view of  FIG. 2 ) that is substantially opposite a front surface  202 . The front surface  202  includes a plurality of independent projections (collectively indicated at  203 ). The independent projections  203  arise from a central portion of the single piece card retainer  200 . The projections  203  are independent in that they are spaced projections, e.g., made of plastic or other polymer, that are flexible due to their material construction. Each independent projection  203  may include two or more sub projections for contacting a graphics card or card insert placed within a slot of a system housing, as further described herein. 
       FIG. 2  also illustrates that the single piece card retainer  200  attaches to a system housing in a rotatable fashion via a connection mechanism, e.g., projections for making a hinged attachment to the housing, such as indicated at  205 . Further, the single piece card retainer may be secured in a closed position via an appropriate securing mechanism. In the example of  FIG. 2 , a detent  206  is provided that mates with a spring loaded (or otherwise biased) element in the housing (not illustrated in  FIG. 2 ). 
       FIG. 3 (A-D) illustrates an example of the single piece retainer card in context. Specifically,  FIG. 3A  illustrates the single piece retainer card of  FIG. 2  attached to a system housing and in a closed position, i.e., securing cards (or card inserts) within slots of the system housing.  FIG. 3B  illustrates the single piece retainer card partially rotated out and disengaged from the securing mechanism of the housing.  FIG. 3C  illustrates further rotation of the single piece retainer card, revealing card slots behind the single piece card retainer.  FIG. 3D  illustrates the single piece card retainer fully rotated to an open position, e.g., for card insertion and/or removal. 
     Turning specifically to  FIG. 3A , the single piece card retainer is attached in a rotatable fashion to the housing  307   a  of the system (e.g., the metal lip of a system case) by projection  305   a , which fits into an aperture provided by housing element  308   a . A similar attachment or connection is provided in a lower portion, but this view is obscured by the operator&#39;s hand in  FIG. 3A . 
     The back surface  301   a  faces outwardly, i.e., it is visible when the user removes the outer system casing, which in turn acts to secure the single piece card retainer in place by virtue of the inside face of the system case (not shown) abutting the back surface  301   a  of the single piece card retainer. 
     The card slots  309   a  (having card inserts therein) are visible behind the single piece card retainer. Four card slots  309   a  are specifically indicated for simplicity sake. The single piece retainer card will be rotated by the user to reveal the ends of the card slots  309   a , from which cards may be inserted or removed. 
     By way of illustrated example,  FIG. 3B  illustrates a user rotating the single piece card retainer outwardly about the pivot point, again afforded by the connection mechanism comprising the projection  305   b . The back surface  301   b  of the single piece card retainer continues to rotate outwardly (toward the user) and the opposite, components of the front surface come into partial view, as indicated by the appearance of the independent projections, one of which is indicated at  303   b . As will be appreciated from review of  FIGS. 2, 3A and 3B , the independent projections will abut the ends of the cards or card inserts when the single piece retainer card is in a closed position ( FIG. 3A ). 
     As the user rotates the single piece retainer card further, as shown in  FIG. 3C , the ends of the card slots  309   c  become more visible. As shown, the front surface  302   c  comes into view, as do the independent projections, one of which is indicated at  303   c . Also, the detent  306   c  comes into view, as it has been disengaged from the projection of the housing by the user&#39;s manual action of rotating the single piece retaining card about the hinge mechanism supplied by projection  305   c  and aperture of the housing element, as described herein. 
       FIG. 3D  illustrates the single piece card retainer fully open, i.e., giving clear access to the ends of the card slots  309   d  for card insertion and removal. Here, the detent  306   d  is clearly visible as well. The user may insert and or remove cards from the card slots  309   d , and then reverse the rotation process to secure the cards within the card slots  309   d . When the single piece card retainer is fully closed, as shown in  FIG. 3A , the independent projections, by virtue of their shape, position and/or material construction, are biased against the ends of the elements (cards or card inserts) contained within the card slots  309   d , ensuring that the element in properly seated. 
     As used herein, the singular “a” and “an” may be construed as including the plural “one or more” unless clearly indicated otherwise.
