Abstract: A three-piece hinge supports a two-panel window assembly in a frame. The hinge includes a base member securable to the frame, a first pivot member pivotably coupled with the base member at a first pivot joint, and a second pivot member pivotably coupled with the base member at a second pivot joint spaced from the first pivot joint. The first and second pivot members each have a glass channel for supporting a panel of the two-panel window assembly. In one arrangement, an insert is secured in a pivoting path of the second pivot member to thereby limit a pivot range of the second pivot member. The hinge eliminates the significant machining time required for prior hinge designs, thereby resulting in a simpler less expensive hinge.

The hinge construction further includes a first coupling device for the rotatable coupling of the first securing part to the hinge part, and a second coupling device for the pivotable coupling of the hinge part to the second securing part. The second coupling device, in order to set a distance between the two components, includes two corresponding, curved coupling surfaces, which run parallel to the pivot axis and of which a first is provided on the hinge part and the second is provided on the second securing part.

Abstract: A toolbox has a novel reverse deadbolt for a latch and hinge. The latch engaging mechanism has attached deadbolts or latching rods which are linearly opposed to each other. Each latch rod mechanism has a hook on the end. This hook effectively reverses the direction of the deadbolt. Thus, when engaged the deadbolt locks around the receiver pins and moves inward. The hinge has a first engaging face that is generally concave radially around a longitudinal axis, and a second engaging face that is generally convex radially around the longitudinal axis. The engaging faces rotate relative to one another around the longitudinal axis in cooperation sufficiently close to allow water to enter them. A passage in the second element is disposed to drain fluid from a fluid communication with the engagement between the engaging faces.

Abstract: A hook device for securement to the substantially horizontal, bottom surface of a table top, bar top, or the like for supporting personal items. The hook device includes a base, a hook, and an attachment mechanism pivotally securing the hook to the base. The attachment mechanism includes a torsion spring that biases the hook into a stored position in which the hook is substantially parallel to the bottom surface of the table top. To use the hook, the hook is pivoted away from the table surface and a personal item, such as a purse, handbag, backpack, coat, or the like is placed on the hook. Once the personal item is removed, the hook returns to its stored position.

Abstract: The installation of a garden window which encloses an opening in the wall of a building is effected by installing a support structure above the wall opening from which the garden window can be hung, then hanging the garden window from this structure in opening closing position and then permanently securing same to the wall. Also included in the invention are the garden window itself and its hanger support to facilitate such installation.

Abstract: A hinge is provided which has a retaining member (40) and a hook member 90. The retaining member is attached to a first component and the hook member is attached to a second component to form a hinge joint. The hinge is able to provide a great degree of freedom of movement for the components because of the use of a hook member in the hinge. The hook member acts as a pivot point, while the retaining member prevents the hook member from being pulled away from the retaining member either laterally or transversely.
