A cup lid clamp assembly inhibiting a lid from falling off of a beverage cup includes a beverage cup for containing a beverage. A lid is removably coupled to the beverage cup. The lid has a drinking aperture extending therethrough to facilitate the beverage in the beverage cup to be consumed. A clamp is positionable around the lid and the clamp frictionally engages the beverage cup to inhibit the lid from is removed from the beverage cup. In this way the lid inhibits the beverage in the beverage cup from spilling. A clasp is movably coupled to the clamp and an engagement is coupled to the clamp. The clasp engages the engagement when the clasp is positioned in a closed position to compress the clamp around the lid.

The invention relates to a food-cooking utensil including: locking/unlocking means; and a control member (6) for controlling the movement of said locking/unlocking means; the control member (6) and the locking/unlocking means co-operating so that the position of the locking/unlocking means varies as a function of the position of the control member (6) in a first relationship while the control member (6) is being moved from its locking position towards its unlocking position, and so that the position of the locking/unlocking means varies as a function of the position of the control member (6) in a second relationship while the control member (6) is being moved from its unlocking position towards its locking position. Food pressure cooking devices.

This invention is a mechanism enabling rapid manual opening and closing of a pressure vessel lid without using tools. A pressure vessel bears two circular mating rings welded to the adjacent rims of the vessel lid and shell respectively with the latter ring grooved to house an O-ring. These mating rings are externally tapered to match the internal tapers of a pair of semi-circular external clamping elements. The mechanism applies tension at the vessel perimeter to draw the external clamping elements radially inward, engaging male and female tapers with sufficient force to compress the O-ring and maintain static clamping of the pressurized lid and shell. Tension is produced by levered rotation of two diametrically-opposed slotted plates where cylindrical pins mounted on the ends of the external clamping elements ride in the plate slots and cam action applies mechanical advantage causing the pins to converge. The mechanism incorporates very few components which are readily manufactured and multiple safety features prevent unintentional actuation.

A coupling device for mounting onto the spout of a faucet is disclosed. The device is connected or connectable to a hose and includes an elastomeric sleeve and a clamp assembly. The clamp assembly includes a housing and a pressure applying member. The housing has a cavity holding the sleeve between a back wall and the pressure applying member. The sleeve receives the externally threaded spout. The pressure applying member is movable to a closed position to compress the sleeve tightly about the spout to releasably secure the device to the faucet. The pressure applying member is also movable to an open position to release the spout from the sleeve. Also disclosed is a cap device for releasably sealing an externally threaded mouth of a bottle or other hollow vessel and making use of an elastomeric sleeve and a clamp assembly similar in many respects to the coupling device.

A door locking device for hydro excavation equipment. The door locking device includes a grapple support housing secured to a door of a debris tank, a lower gripping jaw having a lower pin defining a lower axis about which the lower gripping jaw is configured to rotate, and an upper gripping jaw having an upper pin defining an upper axis about which the upper gripping jaw is configured to rotate. The locking device also includes a yoke having a first end coupled to proximate ends of the lower and upper gripping jaw, and an actuator coupled to a second end of the yoke and configured to extend and retract the yoke to cause the lower and upper gripping jaws to rotate in response thereto about the lower axis and the upper axis, respectively.

The present invention relates to a pail body having a pail end defining a pail opening, a lid closing the pail opening, and a clamping ring clamping the lid onto the pail end, wherein the clamping ring comprises a lever connected to the ends of a split clamping ring, which lever in a closed position clamps the split clamping ring onto the pail end, and in an open position widens the ring, and spring means connecting the lever to at least one of the ring ends, to the clamping ring, and a method for applying the clamping ring to a pail body.

A closing device is provided for a container of a respirator with two container shells (2, 2) joining each other at front surfaces, with at least one tightening strap (4), which encloses a part of a container shell outer surface located at right angles to the front surfaces. Two holding elements (5, 5) are each provided with a recess (6, 6) and are formed at the free ends of the tightening strap (4). A closing element (7) is formed in a U-shaped pattern with two legs (8) and meshes with each recess (6, 6) of the holding elements (5, 5). The legs (8) of the closing element (7) can be pulled out of the recess (6, 6) of the holding elements (5, 5) to take off the tightening strap (4).

A sealing cover for covering an opening of a barrel body includes an outer cover body, an inner cover body, an airtight ring and an operating member. The outer cover body includes two pivot connecting portions. The airtight ring is sleeved on an outer peripheral surface of the inner cover body. The operating member is pivotally connected to the pivot connecting portions and the inner cover body. The operating member is operable to pivot so as to drive movement of the inner cover body between a sealed position and an unsealed position. When at the sealed position, the airtight ring is deformed and airtightly pressed between the barrel body and the outer cover body. When at the unsealed position, the airtight ring restores to its original shape and is configured not to be pressed between the barrel body and the outer cover body.
