Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention is a latch wherein latching and unlatching are accomplished by an inward push of a keeper into the latch housing.




2. Description of the Related Art




Although push-push latches have been proposed in the art, none are seen to provide the positive and reliable operation of the push-push latch of the present invention.




An example of a known push-push latch is described in U.S. Pat. No. 4,655,489 issued to Robert Bisbing on Apr. 7, 1987. The push-push latch of Bisbing uses a spring having a portion under compression and a portion in tension. The Bisbing latch is difficult to assemble and requires one side of the latch housing to be removable for assembly. The simplified design of the present invention allows the use of a one piece housing which reduces manufacturing cost.




SUMMARY OF THE INVENTION




The present invention is a latch wherein latching and unlatching are controlled by an inward push by the keeper towards the latch, generally known as a push-push latch.




The latch includes a housing, containing a hook beam, a shuttle opposite the hook beam, and a compression spring, for biasing the shuttle upward within the housing. The latch mates with a corresponding keeper to secure a moving member, such as a door or drawer, to a nonmoving member, such as the frame of the door or drawer. The latch will typically be secured to the nonmoving member, with the keeper secured to the moving member, but the opposite arrangement will work equally well. It should be noted that the following summary refers to a top, bottom, left, right, etc. for simplicity of reference only, and not to imply that the orientation of the latch is critical to its function.




The housing is generally rectangular, and is preferably made of one-piece construction. The housing is in the form of a shell defining a cavity having an interior, and an opening in its top surface. The housing has a pair of opposing openings in its front and back surfaces. A pair of opposing snap legs extends downward and inward into the housing from the top edges of the opposing openings. A second pair of opposing snap legs extends upward and outward from the bottom of the housing's left and right sides, ending with a ridged surface. The front of the housing further has an additional opening on the same side of the housing as the hook beam. A resilient finger extends from the bottom edge of the opening upward and slightly inward. The bottom of the housing also has a ramp located at the bottom rear corner of the interior below the shuttle of the latch and to one side of the spring. The ramp forms an inclined plane which slants upward in back of the spring and shuttle of the latch.




The hook beam is located within the housing, extending from the top opening towards the bottom of the housing. The hook beam includes a top hook for engaging the keeper, described below. The hook includes a flange extending to one side. A small detent boss projects from the side of the hook opposite the flange. The hook beam also includes a stem. The stem includes a central projection which extends outward towards the shuttle and which preferably has a flat top side. The bottom end of the hook beam further includes a pivot, which is preferably a pair of bosses projecting from either side of the bottom end of the hook beam. The pivot bosses of the hook beam are positioned between the inner snap legs and the bottom of the front and back openings. The motion of the bottom end of the hook beam is rather complex. The pivot bosses are constrained within the front and rear openings in the housing. The front and rear openings are elongated and allow the bottom end of the hook beam to translate to the left or right, as well as for the hook beam to pivot about the central axis of the bosses. The left end of the front and rear openings is notched which additionally allows the pivot end of the beam to move up and down when the pivot bosses are positioned at the left end of the front and rear openings. The bottom end of the hook beam also includes a projection, which projects approximately perpendicularly to the left of the hook beam. The projection preferably has a hook shape.




The shuttle is located opposite the top hook. The bottom portion of the shuttle defines a channel for guiding the compression spring, which abuts the bottom of the housing. The top of the shuttle includes a top surface for making contact with the keeper (described later). The top of the shuttle further includes an overhang for making contact with the top side of the central projection of the hook beam. An arm extends outward from one side of the top of the shuttle in the same direction as the overhang, immediately below the flange extending from the hook beam's hook. A skirt extends downward and to the right from the top portion of the shuttle, being dimensioned and configured to push against the perpendicular projection at the bottom of the hook beam, when the hook beam is in the unlatched configuration.




The keeper includes a mounting plate, preferably having an adhesive backing, and a hook. The keeper's hook is dimensioned and configured to push downward on the shuttle's top portion, and to engage the hook beam's top hook.




The latch will typically be installed within a socket. The socket is shaped to correspond with the shape of the housing, to prevent misalignment of the latch. Upon inserting the latch into the socket, the ridges on the outer snap legs will engage the edges of the socket, securing the latch within the socket. The keeper is then inserted into the latch, where it is secured therein as described below. The adhesive backing of the keeper is exposed, and the moving member to be secured by the latch is brought into its closed position, in contact with the adhesive. When the adhesive is dry, the keeper will be secured in the proper position to engage the latch.




The latching and unlatching cycle begins with the hook beam in its upward vertical position, against one side of the housing opposite the shuttle. To actuate the latch, the moving member is moved into its closed position, thereby bringing the keeper and latch together, and inserting the keeper's hook into the latch. The keeper pushes the shuttle toward the bottom of the housing, causing the shuttle's skirt to push against the hook beam's bottom arm, rotating the hook beam's top hook into engagement with the keeper's hook. As the hook beam's top hook rotates, the detent boss near the hooked end of the beam is snapped onto the left side of the resilient finger of the housing thereby ensuring the proper position of the hook beam's top hook for engagement with the keeper's hook. At this point, the user will release pressure on the moving member, allowing the spring to push the shuttle upward, thereby pushing the keeper slightly upward. As the keeper pulls on the top hook of the hook beam, the hook beam is pulled into a vertical position. Proper vertical alignment of the hook beam is insured by the detent boss near the hooked end of the beam, which is constrained from moving back to its original position by the resilient finger of the housing. Continued upward motion of the shuttle is prevented by the keeper hook, which is held by the hooked end of the hook beam and blocks the shuttle from returning to its original position. The latch is now securely latched.




To unlatch the latch, the moving member is again pushed inward, thereby causing the keeper to push the shuttle inward. The overhang of the top portion of the shuttle pushes down on the hook beam's central projection, causing the hook beam to move down. As the hook beam moves down, the perpendicular projection or arm at the bottom of the hook beam contacts the ramp of the housing which creates a reaction force which rotates the top hook and stem of the hook beam away from the hook of the keeper which allows the keeper's hook to exit the latch. As the top hook is rotated away from the hook of the keeper, the detent boss at the top of the stem of the hook beam is snapped into the right side of the resilient finger of the housing. As pressure is released on the keeper, the shuttle moves fully forward. The shuttle's flange pushes on the side flange of the hook beam's top hook, thereby moving the hook beam back into its original position. Proper vertical alignment of the hook is ensured by the detent boss on the hook beam, which is constrained from moving back to its previous position by the resilient finger of the housing.




It is therefore an object of the present invention to provide a latch wherein latching and unlatching is accomplished by an inward push by the keeper on the latch.




It is another object of the invention to provide a latch where proper alignment of the hook beam of the latch is insured during the latching and unlatching of the latch.




These and other objects of the invention will become apparent through the following description and claims.

. Each boss


100


has a notch or cutout


102


in the form of a circular sector subtended by an angle of less than 180 degrees, being dimensioned and configured to engage the corner


44


.




Referring to

FIGS. 22-28

, the shuttle


16


is illustrated. The shuttle


16


defines a top portion


110


which is “T” shape in top plan view and configured to fit into the wide portion


38


corresponding to the left side


28


of the housing


12


opposite the hook beam


14


. The top portion

includes an overhang


112


which projects towards the hook beam


14


. A flange


116


extends outward from one side of the shuttle


16


, being dimensioned and configured to abut the top flange


84


of the hook beam


14


. The shuttle


16


is spring-biased forward. The shuttle


16


defines a spring channel


118


, dimensioned and configured to contain and guide a compression spring


18


. The shuttle


16


also includes a skirt


120


which extends downward and toward the beam


14


from the top portion


112


, and dimensioned and configured to engage the bottom projection or arm


98


of the hook beam


14


.




Referring to

FIGS. 29-31

, the keeper


20


is illustrated. The keeper


20


includes a top panel


130


and a hook


132


. The hook


132


is dimensioned and configured to pass through the wide portion


38


of the opening


34


of the housing


12


and to be engaged by the hook beam's top hook


80


. The hook


132


of the keeper


20


includes a bottom surface


134


for pushing inward on the top portion


110


of the shuttle


16


. The back of the top panel


130


preferably includes an adhesive


136


for securing the keeper


20


to one of the two components to be latched together using the latch


10


.




The latch


10


and keeper


20


will typically be mounted on opposing moving and nonmoving members, such as a door or drawer and the frame supporting the door or drawer (not shown, and well-known). Typically, the latch


10


will be installed on the nonmoving member, and the keeper


20


will be installed on the moving member, but this may be reversed without affecting the operation of the latch


10


. In addition, both members to which the latch


10


and keeper


20


are installed may be movable. The latch


10


will preferably be installed within a socket, with a preferred and suggested socket having the configuration of two intersecting rectangles, corresponding to the shape of the housing


12


, to ensure proper alignment. Merely inserting the latch


10


into the socket, with the bottom


32


of the housing


12


first, will cause the ridges


62


of the outer snap legs


60


to engage the edges of the socket, thereby securing the latch


10


within the socket. The keeper


20


is then inserted into the latch


10


for latching (as explained below), and the keeper's adhesive backing


136


is exposed. By bringing the moving member towards the nonmoving member, corresponding to the moving member's closed position, the keeper


20


is secured in the proper position on the opposing member to provide for latching and unlatching.




The operation of the latch


10


is illustrated sequentially in

FIGS. 32-39

. The back side of the housing has been broken away to reveal the internal parts of the latch


10


. The initial unlatched position of the latch's components is illustrated in

FIGS. 32-33

. The hook beam


14


is adjacent to the right side


26


of the housing


12


opposite the shuttle


16


with the top flange


84


abutting the shuttle's flange


116


, and detent boss


86


on the stem


88


of the hook beam snapped into the right side of the resilient finger


48


of the housing.

FIGS. 34-35

illustrate the bottom surface


134


of keeper


20


pushing inward on the top portion


110


of the shuttle


16


. As the shuttle


16


is pushed downward, the shuttle's skirt


120


pushes against the hook beam's bottom arm


98


. The shuttle's top portion


110


is simultaneously moved below the top hook


80


of the hook beam


14


. Because the hook beam's opposing bosses


100


are constrained within the housing's openings


40


, the hook beam


14


rotates counterclockwise (in the view shown in

FIG. 34

) so that the detent boss


86


on the stem


88


of the hook beam


14


moves from the left to the right side (in the view shown in

FIG. 35

) of the resilient finger


48


of the housing


12


. Simultaneously, the hook beam's top hook


80


engages the keeper's hook


132


. Proper alignment of the top hook


80


of the hook beam


14


for engagement with the hook


132


of the keeper


20


is insured by the detent boss


86


which is constrained from moving back to its original position by the resilient finger


48


of the housing. At this point, the user will release the pressure on the moving member, allowing the spring


18


to push the shuttle


16


slightly upward. As the shuttle


16


pushes the keeper


20


slightly upward, the hook


132


of the keeper


20


pulls on the top hook


80


of the hook beam


14


which will in turn pull the hook beam


14


into a vertical position. Proper vertical alignment of the hook beam


14


is insured by the detent boss


86


on the stem


88


of the hook beam which is constrained from moving back to its original position by the resilient finger


48


of the housing. Continued upward motion of the shuttle


16


is prevented by the keeper's hook


132


which is held by the top hook


80


and blocks the shuttle


16


from returning to its original position. The latch


10


is now securely latched as illustrated in

FIGS. 36-37

.




The latch


10


is unlatched by pushing inward on the moving member, which again causes the bottom surface


134


of keeper


20


to push inward on the top portion


110


of shuttle


16


. The overhang


112


of the top portion


110


of shuttle


16


pushes down on the top side


96


of the central projection


94


of hook beam


14


. The downward push on the central projection


94


causes the bottom end of the hook beam


14


to move downward, the bottom end of the beam


14


now being located at the end of the opening


40


closest to the shuttle


16


. This downward movement brings the corners


44


into interference with the notches


102


. This interference with the notches


102


prevents translation of the bottom end of the hook beam


14


along the openings


40


. As the hook beam


14


is pushed down by the overhang


112


of the shuttle


16


, the bottom of the bottom arm


98


of the hook beam


14


contacts the ramp


52


of the housing


12


which creates a reaction force which rotates the top hook


80


and the stem


88


of the hook beam


14


away from the hook


132


of the keeper


20


as shown in FIG.


38


. Simultaneously, the detent boss


86


at the top of the stem


88


of the hook beam


14


is snapped into to the left side of the resilient finger


48


as shown in the view of FIG.


39


. As the hook


132


of the keeper


20


is released from the top hook


80


of the hook beam


14


, the shuttle


16


is pushed forward by spring


18


. The shuttle's flange


116


engages the hook beam's top flange


84


, thereby moving the hook beam


14


back into its original position. Proper vertical alignment of the hook beam


14


is ensured by the detent boss


86


on the hook beam


14


which is constrained from moving back to its previous position by the resilient finger


48


of the housing


12


. The unlatching process is now complete, and the latch


10


is ready to repeat the cycle beginning with the view shown in FIG.


32


.




The assembly of the latch


10


is illustrated in FIG.


40


. Spring


18


is inserted into the spring channel


118


of the shuttle


16


, and the shuttle


16


is positioned adjacent to the hook beam


14


so that the flange


116


of the shuttle


16


abuts the bottom of the hook's top flange


84


and the top surfaces of the top hook


80


and the top portion


110


of the shuttle


16


are level with one another. The preassembled hook beam


14


, shuttle


16


, and spring


18


are then inserted through the top opening


34


of the housing


12


. The spring


18


is now compressed between the shuttle


16


and the bottom


32


of the housing


12


. The hook beam's bosses


100


snap into the openings


40


of the housing


12


, and are engaged by the resilient inner snap legs


42


. The shuttle's flange


116


abuts the hook beam's top flange


84


, thereby securing the shuttle


16


, hook beam


14


, and spring


18


within the housing


12


. In the unlatched, at rest position, the hook beam


14


is adjacent to the right side


26


of the housing


12


, with the top hook


80


resting against the overhang


112


of the top portion


110


of the shuttle, and the top flange


84


abutting the shuttle's flange


116


.
