Abstract: A casement window hinge eliminates the use of rivets in the pivot between the sash arm and guide arm such as require a high force deformation of an element to a precise compression that varies according to a “tolerance stack up” between four controlled dimensions of the parts being assembled: the length of the rivet, the deformation of the rivet head, and the thickness of the two arms being assembled. The invention eliminates two of these dimensions through the use of integrally molded pivot pins that fit into a bore in the second arm and which are plastically flanged. Resistance to a pull-out of wood screws that are countersunk into a plastic sash arm is provided by exaggerated counter sinking with undersized countersink bores.

Abstract: A slide hinge has a stationary bracket, a slide, a pivot pin and a rotatable bracket. The stationary bracket is hollow and has a chamber and a rail slot.

The rotatable bracket is mounted rotatably on the pivot pin. The slide hinge has merely four components so that fabricating the slide hinge is easy and fast. Therefore, the manufacturing cost of the slide hinge is low.

Abstract: An object is to provide a potable blower grip which can sufficiently reduce vibration and can lessen the worker's fatigue fully. A soft material grip 2, attached to a handle 1 of a portable blower 100 and held by a worker P has a corrugation 2X and the corrugation 2X is arranged so as to face in the vertical direction V, when the portable blower 100 is tilted forward to take a working posture, and thus the weight of the portable blower 100 is applied to one hand at the time of working via the corrugation 2X which faces in the vertical direction V. Accordingly, the crushing of the corrugation 2X is prevented and also the contact area between the grip 2 and the hand is minimized by the corrugation 2X to sufficiently reduce the vibration transferred to the hand.
