Sliding Catch Patents (Class 292/106)
  • Patent number: 4871203
    Abstract: A gate latch structure with a striker bar mounted on a fence gate hinge mounted on a fence. The latch structure also includes a pivot latch member pivotally mounted on a latch mounting back plate mountable on a fence post or the middle end of the other half of a double gate with the pivot latch member and the back plate symmetrical for turn over mounting adaption to left hand opening and right hand opening gate sections. The striker bar receiving opening in the pivot latch member has a rear edge recessed back from the rear end of the striker bar receiving opening in the latch mounting back plate. The back plate has upper and lower striker bar entrance guide ramps and the pivot latch member has two entrance lifting ramps only one in use depending on right or left gate mounting by entrance of the striker bar. Pivot latch member pivotal movement about the pivot screw mounting thereof is limited by a limit screw engaging an end of an arcuate slot therein.

  • Patent number: 4826221
    Abstract: Latch mechanisms for latching two bodies in both tension and shear. A longitudinally extending latching bolt is associated with a latching assembly having an overcenter link mechanism controlled by a lever. The overcenter link mechanism includes a slot cooperating with a pin to provide two effective lengths to the fully extended linkage. A laterally extending notch provides a shoulder intermediate the ends of the slot to receive the pin. A keeper is slidably associated with a keeper assembly to engage a recess in the longitudinally extending bolt to prevent its withdrawal from the keeper assembly. A locking surface in the recess engages the keeper. A slide member may extend over the recess so that the keeper is selectively prevented from engaging the recess for purposes of retracting the bolt.

  • Patent number: 4801173
    Abstract: A removable folding roof for a motor vehicle, especially for a passenger motor vehicle, which extends between a windshield frame and a roll bar and which includes laterally disposed longitudinally extending girders, several struts extending parallel to the girders and a roof covering. The folding roof is detachably retained at the windshield frame and at the roll bar by means of locking mechanisms. To achieve an effective support of the folding roof and a simple assembly operation for latching and tensioning the folding roof to the vehicle body, the longitudinally extending girders are placed on the upwardly extending tensioning levers of the locking mechanisms which are then pivoted downwardly along with the edges of the top to a latched position. An automatic tensioning of the folding roof in the vehicle transverse direction and simultaneous latching of the roof to the vehicle body is achieved by the pivoting of the tensioning lever to a lowered position.

  • Patent number: 4759574
    Abstract: A latch assembly includes a hook having an opening engageable to a keeper. A side plate having a straight slot and an angle slot is mounted to the hook via posts. A spring is provided to bias the plate so that it partially overlaps the opening. The plate prevents a latch handle from being moved into its closed position unless the hook is fully engaged onto a keeper.

  • Patent number: 4683731
    Abstract: A latching device for luggage is described, wherein a latching member having a hasp engaging angled finger is rotatably mounted in a frame member. A spring member rotatably mounted atop the latching member has a key receiving recess, a locking tab for preventing rotation of the latching member, serves to urge the latching member against the base member and yieldably holds a ball in recesses in the base member. A hasp has a boss with a curved slot for receiving the hasp engaging finger on the latching member. A cover plate is rigidly attached to the latching member and is rotatably disposed on a base member which has a raised rib. A side wall of the cover plate rides across the rib camming the latching member and angled finger upwardly against a wall of the slot to draw the hasp and latching device toward each other.

  • Patent number: 4648640
    Abstract: A sliding gate latch device having concentric mutually slideable tubular members, an inner one mounted to the sliding gate and the other sliding thereover, the inner tubular member carrying an articulated jaw which engages a pin or bolt on a fixed structure to which the gate is closed. A combination lock is adapted to lock the tubular members together. A rotatable tongue also positions itself within the outer tubular member when the jaw is in the locked position to prevent opening when the tubular members are locked together.

  • Patent number: 4511166
    Abstract: A handle-operated lock for use on a sliding door has hook-shaped, rotary latch bolts which project from opposite sides of a housing for selectively engaging spaced strikes to selectively retain the sliding door in open or closed positions. A compression coil spring is carried within the housing for biasing the latch bolts toward their latched positions. Inside and outside rotary handles are provided for selectively rotating the latch bolts to unlatch them in opposition to the action of the spring. Inner and outer rotary tumblers provided within the housing to drivingly connect the rotary handles with the rotary latch bolts. A slidable latch-operator is provided near the inside handle for movement between a locked position wherein it prevents rotation of the outer tumbler to disable the outside handle from operating either of the bolts, and an unlocked position wherein it permits the outside handle to operate the latch bolts.

  • Patent number: 4498695
    Abstract: A latching mechanism and pressure-operated safety lock for a pressure vessel such as a pressure fryer, the invention positively locks a lid of a pressure fryer over the cooking pot by means of a latch mounted on the distal end of a bar which centrally engages the lid to bias the lid into a pressure-tight relation with upper peripheral edges of the pot. The latch includes a spindle having a hook element formed at the lower end for engaging a catch mounted on the body of the fryer on tightening of the latch by rotation of a hub mounted on the spindle. The hub is provided with radially extending handles which facilitate rotation thereof. A safety lock operated by pressure generated by food cooking within the fryer cooperates with the latch to prevent opening of the lid when pressure of at least a predetermined value exists within the fryer.

  • Patent number: 4351288
    Abstract: A mechanism for inhibiting the locking movement of a hooklike oven door latch member when an associated keeper fixed to the oven door is not in its proper position for engagement with the latch member. Inhibiting the locking movement of the latch member precludes the closing of associated interlock switches to prevent the user from initiating a high temperature oven cleaning cycle or a microwave cooking cycle without proper locking of the oven door. The mechanism includes a stop member biased at a latch movement inhibiting position, the stop member being moved to a non-inhibiting position by engagement with the keeper when the oven door is moved to a fully closed position.

    Abstract: A briefcase is provided with a two-part releasable fastening device, the first part of which includes a movable fastening member for releasably fastening the parts together. The first part of the device further comprises a ball which, when the case is inverted, is urged by gravity into a retaining position in which it prevents releasing movement of the fastening member. When the lid of the case is uppermost, the ball permits movement of the fastening member to release the second part of the device.

  • Patent number: 3991902
    Abstract: A simple manually operable sanitary latch is provided to retain a cover on a pan while heating or for lifting the pan by the lid, as particularly useful in an environment such as a restaurant or hospital. The latch comprises two members, one being a U-shaped hook affixed to the cover at the edge, so that it goes under the upper lip of a mating pan. On an opposite edge of the cover is a movable latch member retained by a strap like bracket affixed substantially parallel to the cover, which permits the latch to move normally to the edge of the lid. This movable latch has an outermost hook for registering under the lip of the mating pan and an innermost abuttment member that restricts the extent of movement away from a latched position where the cover can be removed.
