A device may be secured to another device using a latch. For example, a slam latch may be used to secure a first device within a second device (e.g., within a housing of the second device.
In some implementations, an apparatus is provided. The apparatus includes a retention portion. The retention portion is configured to prevent a first device, coupled to the latch, from being removed while the retention portion is in a first configuration. The retention portion is configured to allow the first device to be removed while the retention portion is in a second configuration. The latch also includes a spring portion coupled to the retention portion, the spring portion configured to allow the retention portion to transition between the first configuration and the second configuration.
Certain embodiments of the invention will be described with reference to the accompanying drawings. However, the accompanying drawings illustrate only certain aspects or implementations of the invention by way of example and are not meant to limit the scope of the claims.
As discussed above, a device may be secured to another device using a latch. For example, a latch may be used to a power supply (e.g., a first device) within a second device (e.g., a network switch, a chassis, etc.).
The strength of the latch 100 (e.g., the compressive strength, the latch's resistance to deforming, etc.) and the force of the spring are tightly coupled in the latch 100. For example, to make the latch 100 stronger (e.g., to increase the compressive strength, to increase the resistance to deforming, etc.) the strip portion 110 may be made thicker (e.g., thicker metal, thicker plastic, etc.). However, making the strip portion 110 thicker also increase the force of the spring. This, in turn, increases the force that a user needs to apply to overcome the force of the spring and move the tabs 111.
If the strip portion 110 is made thinner to decrease the force of the spring, this may decrease the strength (e.g., compressive strength of the latch). When an impact or other movement occurs to the first device and/or the second device, the strip portion 110 of the latch 100 may deform, bend, buckle, etc., and may not be able to properly retain or secure the first device within the second device.
The latch 200 also includes a spring portion 220. The spring portion 220 may have a spring force that may be created or caused when the spring portion 220 pushes against a feature of surface of the second device. The spring portion 220 may apply a force that causes the retention portion to remain in a first configuration, as discussed in more detail below. The spring portion 220 allows the retention portion 210 to pivot about securement mechanism 215 when a force is applied to and/or removed from the handle portion 212, as discussed in more detail below.
A user may apply a force on the handle portion 212 (in the direction indicated by the dashed arrow) of the latch 200. The force applied by the user may overcome the force of the spring (e.g., the cantilever spring) of the spring portion 220 and may move the tabs 211 such that the tabs 211 are disengaged from the feature or surface on the second device. The force of the spring (of the spring portion 220) may cause the retention portion 210 to return to its original position (before the user applied a force to the handle portion 212) once the user discontinues applying the force (e.g., stop applying the force, removes the force, etc.) to the handle portion 212.
The retention portion 210 may be in different configurations or positions. For example, the retention portion 210 may be in a first configuration or a second configuration. In the first configuration or position, retention portion 210 may prevent the first device from being removed from the second device. For example, the tab 211 of the retention portion 210 may engage (e.g., contact, touch, abut, etc.) with a feature/surface of the second device to prevent the first device from being removed from the second device. In the second configuration, when the user applies a force on the handle portion 212, the retention portion 210 may swing toward the direction indicated by the dashed arrow, into the second configuration or position. In the second configuration, the retention portion 210 may allow the first device to be removed from the second device. For example, the tab 211 of the retention portion 210 may disengage from the feature/surface of the second device to allow the first device to be removed from the second device. Although the present disclosure may refer to a number of configurations/positions, various numbers of configurations/positions may be used in other embodiments. For example, the latch 200 may be movable to configurations and/or positions that are between the first configuration and second configuration.
The spring portion 220 may allow the retention portion 210 to transition between the first configuration and the second configuration. For example, the force of the spring in the spring portion 220 may cause the retention portion 210 to be in the first configuration/position. When a user applies a force to the handle portion 212 to overcome the spring force, the retention portion 210 may move in the direction indicated by the dashed arrow to the second configuration/position. When the user no longer applies the force to the handle portion 212, the force of the spring in the spring portion 220 may cause the retention portion 210 to move back (e.g., spring back) to the first configuration/position. For example, the retention portion 220 may move in a direction that is opposite to the dashed arrow.
As illustrated in
In other embodiments, the retention portion 210 and the spring portion 220 may be separate pieces that are detachable from each other. For example, the retention portion 210 may be separable and/or detachable from the spring portion 220. The retention portion 210 may be attached to the spring portion 220 using various attachment mechanisms. For example, the retention portion 210 and/or the spring portion 220 may include slots, groves, rails, apertures, protrusions, etc., that allow the retention portion 210 to be attached, secured, connected, and/or coupled to the spring portion 210. In some embodiment, the latch 200 may be more configurable based on user preferences or requirements when the retention portion 210 and the spring portion 220 are separate pieces. For example, the compression strength of the retention portion 210 may be increased by using a different material in the retention portion 210 than the material in the spring portion 220. Using a different material in the retention portion 210 than the material in the spring portion 220 may be possible when the retention portion 220 is separable from the spring portion 220.
In some embodiments, the retention portion 210 and the spring portion 220 may initially be separate pieces but may be coupled into a single continuous piece when the latch 200 is manufactured or constructed. For example, the retention portion 210 may be welded, fused, etc., to the spring portion during manufacturing.
The spring portion 220 may include different types of springs, including, but not limited to, a flat spring, a compression spring, a tension spring, a torsion spring, a flat spring, a cantilever spring, a leaf spring, etc. Although
In one embodiment, the retention portion 210 and the spring portion 220 may be made of the same material. For example, the retention portion 210 and the spring portion 220 may both be constructed of steel. In another embodiment, the retention portion 210 and the spring portion 220 may be made of different materials (e.g., different metals, different plastic materials, different polymeric materials, different composite materials, etc.). For example, the retention portion 210 may be constructed of steel and the spring portion 210 may be constructed of aluminum.
In one embodiment, the tab 211 may protrude through an opening (e.g., a hole, an aperture, etc.) in a housing of the first device to interface or engage with the feature/surface of the second device. The tab 211 may prevent the first device from being removed from the second device when the tab 211 engages or interfaces with the feature/surface of the second device. As discussed when the retention portion 210 is in the second configuration, the tab 211 does not interface or engage with the feature/surface the second device to allow the first device to be removed from the second device.
As discussed above, the handle portion 212 allows may be used to allow a user to transition the retention portion 210 between the first configuration/position and the second configuration/position. The handle portion 212 may provide the user with a more comfortable portion of the latch, where the user may apply a force (e.g., a pushing or pulling force) to move the retention portion 210 to a second configuration. The handle portion 212 may also include other materials, such as rubber of foam padding, etc. In other embodiments, the size, shape, and/or location of the handle portion 212 may be different. For example, the handle portion 212 may have a curved shape that allows the handle portion 212 to better conform to a user's thumb. In another example, the handle portion 212 may be located at a location that is higher or above the retention portion 220.
In one embodiment, the retention portion 210 may be less likely to deform, bend, buckle, etc., than the spring portion 220. For example, the retention portion 210 may have more may have more compressive strength than the spring portion 220 (e.g., may have more resistance to deforming, bending, compressing, etc.). The retention portion 210 may be stronger, stiffer, etc., than the spring portion. As illustrated in
The latch 210 also includes a securement mechanism 215. The securement mechanism 215 may be configured to attach or secure the latch 200 to the first device (e.g., to a housing of the first device). The securement mechanism 215 includes a hole, an opening, an aperture, etc., configured to receive a screw, bolt, etc. In one embodiment, the securement mechanism 215 may be a pivot point that allows the retention portion 210 to swing or pivot between the first configuration/position and the second configuration/position. For example, the retention portion 210 may swing/pivot about the securement mechanism 215. In other embodiments, other types of securement mechanisms may be used. For example, slots, grooves, rails, etc., may be used to secure or attach the latch 200 to the first device.

Various units, circuits, or other components may be described or claimed as “configured to” perform a task or tasks. In such contexts, the phrase “configured to” is used to connote structure by indicating that the units/circuits/components include structure (e.g., circuitry) that performs the task or tasks during operation. As such, the unit/circuit/component can be said to be configured to perform the task even when the specified unit/circuit/component is not currently operational (e.g., is not on). The units/circuits/components used with the “configured to” language include hardware—for example, circuits, memory storing program instructions executable to implement the operation, etc. Reciting that a unit/circuit/component is “configured to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. 112, sixth paragraph, for that unit/circuit/component. Additionally, “configured to” can include generic structure (e.g., generic circuitry) that is manipulated by software and/or firmware (e.g., an FPGA or a general-purpose processor executing software) to operate in manner that is capable of performing the task(s) at issue. “Configured to” may also include adapting a manufacturing process (e.g., a semiconductor fabrication facility) to fabricate devices (e.g., integrated circuits) that are adapted to implement or perform one or more tasks.
The foregoing description, for the purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the embodiments and its practical applications, to thereby enable others skilled in the art to best utilize the embodiments and various modifications as may be suited to the particular use contemplated. Accordingly, the present embodiments are to be considered as illustrative and not restrictive, and the invention is not to be limited to the details given herein, but may be modified within the scope and equivalents of the appended claims.
