A foot-operated door opener including a base secured to a door and an extension having a top surface and a bottom surface, side surfaces and side edge surfaces. The foot-operated door is configured such that a door may be pulled open using either the top or bottom of a user's foot or foot covering. The side and side edge surfaces allow for operation in a confined space where the user needs to stand to the side of the door when operating.

A kit for articulated connection between dividing panels having a pair of male pieces with a coupling protrusion; and a pair of female pieces with a coupling hole, the protrusions engage the holes when relative vertical movement between the pair of male and female pieces is produced when fixed to the panels. One of the first or second pair of pieces is configured with a depression such that the coupling protrusion or the coupling hole is arranged in the groove. The kit includes an auxiliary piece with a retaining pin actuatable with a lever and with an angled end, fixable to the lateral wing of one of the male pieces, the pin remaining parallel to the lateral wing and outside the panel. Regulated by the lever, the angled retaining end of the pin can be arranged in at least two positions: a release position and a locking position.

A drive arrangement (10) has first and second wheels (12, 14) and an endless loop member (16). The path of the member (16) is defined in part by a third wheel (18), between the wheels (12, 14). The wheel (18) is movably mounted so that the length can be changed for the path of the member (16) as it passes around the wheel (18), between the wheels (12, -14). Accordingly, the member (16) can be tightened or slackened around the wheels (12, 14), so that the wheels (12, 14) can be coupled to convey drive from one to the other, through the member (16), or disengaged, so that drive is not conveyed.

A movable barrier operator (200) comprises a motor (201) having an output drive shaft that itself comprises a first end (202) and a second end (203) that is disposed opposite to the first end. The movable barrier operator also comprises a hand-operated chain hoist (204) that is connected to the second end of this output drive shaft. By one approach, the movable barrier operator also comprises a reduction mechanism (207) and a transmission (210). The reduction mechanism is disposed parallel to and laterally of the motor and comprises a movable barrier drive output (208) and an input drive shaft (209). The transmission, in turn, is disposed to couple the first end of the output drive shaft of the motor to the input drive shaft of the reduction mechanism.

A window operator handle securable to a casement window operating drive shaft is described. The handle is movable between an operating position to a folded position The handle has a body housing that has a cavity which includes an operating mechanism. The operating mechanism has an assembly body secured to the housing, a pivotal member positioned in a first section of the assembly body and a sliding member positioned in at least a second portion of the assembly body. The pivotal member is adapted to pivot from a first position to a second position as the handle is moved from a first position to a second position. The pivotal member is held in one position and the other position by the sliding member. The sliding member is retained in contact with the pivotal member by a spring means in said assembly body.
