Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to the field of latching devices, and, more particularly, to a handle actuated latch assembly having a foldable handle.




2. Brief Description of the Prior Art




Latch assemblies are relied on in a number of applications for securing items together, such as panel doors, containers, cabinets and compartments, as well as for securing components within a panel or cabinet. For example, a variety of fastening devices are often employed to secure electronic components in a panel or cabinet, or on a circuit board or other unit. The cabinet may have a lockable door to provide access to individual components. Some cabinets or units may include rack assemblies where electronic components are mounted on a rack for insertion and removal thereof. Generally, the components themselves which are installed in a rack or cabinet, may receive a plurality of wires or connectors which are connected thereto. Often, the electronic components must be removed for repair, upgrading or replacement. In some cases, rack components will preferably have a handle or grip for facilitating removal of the component from a cabinet or box or the like. In many cases the handle may be a permanently installed protruding pull member which can be gripped by a user to slide or insert a component into and out of the panel.




In some cases the handles or pulls can also be hinged so that they may fold to conserve space. The more space that is conserved enables a greater number of components to be installed within the cabinet, or, a smaller cabinet to be used.




There exists, however, applications in which hot-plugging of components is routinely performed. Power supplies are a type of component which are installed in a cabinet. For example, in certain applications, power supplies are “hot-swappable”, requiring the system to continue to run while the power supplies are being changed. Insertion and retraction of a power supply in such applications generally requires that electrical connectors in the power supply be engaged or disengaged as the power supply is being inserted or retracted, respectively. Often the power supplies can have weights in excess of twenty pounds and therefore require a considerable force to release the power supply from a cabinet or frame, and also, at the same time, to disengage a connector. Furthermore, once the power supply is installed in position within a cabinet, panel or other unit, it is desirable to maintain it in its engaged position, so that it will not become inadvertently disengaged by an unexpected force, vibration, heat or the like.




While latching and fastening devices may be applied to retain components, such as, for example, a power supply, into a panel, it is desirable to use as little space as possible to leave room for other components and to minimize the size of the panel or unit volume. Camming action has been used in latching assemblies. For example, U.S. Pat. No. 5,669,638 “Fastening Device” issued on Sep. 23, 1997 to Glenn E. Anderson, et al, and assigned to Southco, Inc., the complete disclosure of which is herein incorporated by reference, discloses a fastening member with a cam mechanism used to withdraw a slide member.




A need exists for a folding down handle which can provide a controlled pushing and pulling action on actuation for retraction and insertion of a member to which the handle is installed.




SUMMARY OF THE INVENTION




A novel fold-down handle device for attachment to a member to provide a controlled pushing and pulling action on actuation to facilitate insertion and retraction, respectively, of a member to which the handle device is installed, the fold-down handle device further including a locking mechanism to lock the handle against actuation. A gripping portion is provided to actuate the foldable handle device and can also be used for transport of the member to which the foldable handle device is installed when the member is removed from a panel or being transported to a panel or unit for insertion therein.




It is an object of the present invention to provide a latching device wherein the folding of a handle operates to actuate the latching device.




It is a further object of the present invention to accomplish the actuation of a pawl member by pivotable movement of a handle to insert and retract a pawl member.




It is a further object of the present invention to provide a locking mechanism which can secure the handle from actuation to prevent unauthorized access.




Another object of the present invention is to provide a locking mechanism to lock the handle in its folded position.




Another object of the present invention is to provide a handle which can be lockable in a folded position and lifted to be maintained in a vertical position.




It is another object of the present invention to accomplish the above objects where the handle is provided as a generally u-shaped member.




It is another object of the present invention to accomplish the above objects where the handle is provided as a generally t-shaped member.

releases from the frame panel


220


and moves from its solid line position to a position shown by the broken line pawl


116


′.




The component to which the handle device


110


is to be installed, such as, for example, the front panel


221


is prepared by providing an aperture


225


through which the housing root


170


can pass. The foot


170


is then secured to the panel


221


by installing the retaining member


180


on the foot


170


.




Referring again to

FIG. 8

, the notch


162


provided on the back of the pawl


116


regulates the position of the pawl


116


relative to the housing


112


when the handle


111


is raised. The notch


162


can provide additional clearance within the pawl receiving slot


150


to enable the pawl


116


to retract to its broken line position


116


′ shown in FIG.


7


.




Detent means is provided for positioning the handle


111


in the closed and raised positions, respectively. For example, an indented portion


147


,


148


is shown at each extreme end of the cam groove


137


, there being a corresponding indented portion on each extreme end of the opposing cam slot


138


(not shown). The indented portions


147


,


148


can be provided to facilitate positioning the cam pin


143


to maintain it in the cam grooves


137


,


138


at a location which secures the pawl


116


with the frame


220


or retracts the pawl


116


from the frame


220


. The extreme position of the handle


111


′ shown with the cam pin


143


lowered in the cam groove


137


beyond the indented portion


147


corresponds to the pawl


116


′ position where it is released from the frame


220


. When the handle


111


is


25


raised to this position, the pawl


116


moves sideways relative to the housing


112


to the broken line position


116


′. This feature is preferably provided to ensure that the pawl notch


161


is fully disengaged from a keeper or other member or surface to which it is attached. For example, if the pawl


116


is associated with plugs or connectors, the release feature can facilitate withdrawal of such plugs or connectors.




The detent means, described above, also serves as positioning means for holding the handle


111


in its extreme positions—fully opened (vertical) or fully closed (horizontal). The positioning means releasably maintains the handle


11


which can be selectively moved into and out of the positioning location.




Preferably, locking means is provided to secure the handle


111


against unauthorized opening. The locking means is provided to lock the handle


111


with the housing


112


so that pawl


116


can not be actuated. The locking device is shown in

FIG. 8

comprising a first fastening part


190


and a second fastening part


191


. The first fastening part is provided for installation in a bore


192


of the handle


111


. The housing


112


has a seat


194


provided to carry the second fastening part


191


therein. The second fastening part


191


is aligned in the housing


112


to correspond to the first fastening part


190


. The fastening parts


190


,


191


can be connected to secure the handle


111


with the housing


112


. Preferably, a spring


195


is provided to raise the stud


190


from the connection with the receptacle


191


. A bushing or retainer


196


is also provided to facilitate securing the stud to the handle


111


to prevent it from falling out.




The fastening parts can comprise, for example, a quarter-turn fastener, such as a stud member and receptacle, as represented by the elements


190


and


191


, respectively. The stud


190


and receptacle


191


can be those which are supplied by Southco, Inc. of Concordville, Pa. Other fastening parts can be employed with the present invention. For example, it is further conceivable that a slam-action type locking arrangement can be achieved, as well as the use of screw or tool shaped configured fasteners. In addition, a key lock or other suitable locking or securing device can also be employed.




It will be apparent to those skilled in the art that various modifications can be made to the handle device invention without departing from the scope and spirit of the invention, and it is intended that the present invention cover modifications and variations of the handle device which are within the scope of the appended claims and their equivalents.
