  • Patent number: 9566995
    Abstract: A hinge for pivotally joining a first frame member and a second frame member of a frame of a stroller may include a first housing portion, a second housing portion, a release actuator and a locking member. The first housing portion may be operably coupled to the first frame member. The second housing portion may be operably coupled to the second frame member. The release actuator may be configured to operate to enable the hinge to shift between a locked state and an unlocked state. The locking member may be configured to move in an axial direction responsive to shifting between the locked state and the unlocked state. The external periphery of the locking member may include a first incline surface that engages both the first housing portion and the second housing portion in the locked state.

  • Publication number: 20160347344
    Abstract: A brake system for applying frictional braking to a mobility assembly of a stroller may include a first brake assembly, a second brake assembly, an operator and a brake balancer. The first brake assembly may be operably coupled to a first wheel of the mobility assembly and to a first cable. The second brake assembly may be operably coupled to a second wheel of the mobility assembly and to a second cable. The operator may be configured to be actuated by a user to apply tension to a third cable. The brake balancer may be operably coupled to the first and second brake assemblies and to the operator via the first, second and third cables, respectively. The brake balancer may be configured to substantially equalize braking applied to the first and second brake assemblies responsive to actuation of the operator.

  • Patent number: 8567071
    Abstract: A utility knife comprises a blade carrier movable between retracted, extended and positions. A latch is movable with the blade carrier for locking the blade carrier in position. The blade carrier comprises a locking tab movable between a first position where the locking tab is engaged with the blade and a second position where the locking tab is released from the blade. An actuator moves the locking tab from the first position to the second position when the blade carrier is in the intermediate position and the actuator is moved to the unlocked position. The latch is engageable with a holder when the blade carrier is in the intermediate position. A retention member holds the blade on the plate where the retention member cannot be inserted into a notch on the blade. A blade guide guides the blade between the retention member and the plate.

  • Patent number: 8539680
    Abstract: A utility knife includes a first housing portion carrying one of a strike plate and a sliding nut assembly and a second housing portion carrying the other one of the strike plate and the sliding nut assembly. The sliding nut assembly includes a rotatable screw and a sliding nut. The sliding nut is movable between a first position where the sliding nut is positioned behind the strike plate and a second position where the sliding nut is positioned spaced from the strike plate. When the sliding nut is in the first position, the sliding nut engages the strike plate upon rotation of the screw to draw the first housing portion toward the second housing portion.

  • Patent number: 8539677
    Abstract: A utility knife comprises a first housing portion carrying a strike plate and a second housing portion movable relative to the first housing portion between a closed position and an open position. The second housing portion carries a locking member. An overlapping locking mechanism locks the first housing portion to the second housing portion in a first direction when the first housing portion is moved relative to the second housing portion in a second direction. The locking member is movable between a first position in which it engages the strike plate to prevent the first housing from moving relative to the second housing in the first direction and a second position in which it does not engage the strike plate and allows the first housing to move relative to the second housing in the first direction.

  • Patent number: 8430383
    Abstract: A clamp comprising a bar supporting a movable jaw having a first support surface. The bar is slidably received in a jaw body and the jaw body supports a fixed jaw. A support is slidably disposed on the bar and has a second support surface that is coplanar with the first support surface such that the clamp can be supported on the first support surface and the second support surface on a surface. In one method of operating the clamp a work piece is positioned directly on the bar. In another method of operating the clamp the movable jaw is moved relative to the fixed jaw and is stopped by the engagement of the support with the body.

  • Patent number: 7984895
    Abstract: A jaw assembly for a clamp is provided that comprises a jaw body having a jaw rotatably mounted on the jaw body. A locking member is movable between a first position where the jaw is locked relative to the jaw body and a second position where the jaw is unlocked relative to the jaw body such that it can rotate relative thereto. A clamp is also provided that incorporates the jaw assembly. In the unlocked position the jaw can pivot such that it can orient itself relative to the workpiece and in the locked position the jaw is fixed such that it can clamp the edges of a workpiece. A method of operating a clamp is also set forth.
