Abstract: A spindle locking apparatus for power tools having a spindle mounted for rotation within a tubular housing. The locking apparatus includes a locking sleeve disposed between the spindle and its tubular housing, a locking collar surrounding the tubular housing radially outboard of the locking sleeve, and a set of drive pins mechanically coupling the locking collar to the locking sleeve through axial slots in the tubular collar. The inner periphery of the locking sleeve is shaped to lockingly engage a flat-sided portion of the spindle, and a spring element biases the locking sleeve away from the flat-sided portion of the spindle to unlock the spindle. The locking collar is axially shiftable against the spring bias as permitted by the slots in the tubular housing to bring the locking sleeve into locking engagement with the flat-sided portion of the spindle to prevent spindle rotation.

Abstract: A Napoleonic chair includes a plastic seat plate, front chair legs, rear chair legs, connecting rods between front and rear chair legs, and a plastic back. The front chair legs comprise front chair leg mounting elements composed of steel tube and plastic casing tubes which sleeve the periphery of the front chair leg mounting elements, while the rear chair legs comprise rear chair leg mounting elements composed of steel tube and plastic casing tubes which sleeve the periphery of the rear chair leg mounting elements. The connecting rods between front and rear chair legs include a steel tube and a plastic casing tube which sleeves the periphery of the steel tube. One end of each longitudinal pipe of the rear chair leg mounting elements is inserted into the plastic back. Two ends of the steel tubes of the rods are inserted into the plastic tubes of the front and rear chair legs, respectively.

Abstract: A chair includes a backrest frame, an armrest frame detachably mounted on the backrest frame and a seat frame detachably mounted between the backrest frame and the armrest frame. Thus, the seat frame and the backrest frame are combined together easily and quickly so that a user can assemble and disassemble the chair by himself without needing aid of any hand tool, thereby facilitating the user assembling and disassembling the chair. In addition, the armrest frame, the seat frame and the backrest frame are detached from and laminated with each other before assembly so as to reduce the whole volume of the chair and to decrease the cost of packaging, storage and transportation of the chair.

Abstract: A detachable chair includes a first frame member including two first side rails having a lengthwise slit, front first cross rails, and rear second cross rails; a second frame member including two second side rails, first seat rails having either end portion projecting laterally out of the second side rail, and a second seat rail disposed rearward of the first seat rails and having either end being about flush with an outer surface of the second side rail; and a backrest including two side sheaths adapted to insert through the slits and fastened by rods. Inserting the second frame member through a gap between one second cross rail and one first cross rail until being stopped by the first frame member with the second side rails rested upon one first cross rail will assemble the inclined frame members as a chair.

Abstract: A chair and kit for producing a kit. A plurality of legs and cross-members are connectable together to form a chair frame. A leather seat portion and back portion are mounted to the frame and secured together by lacing extending through the opposed ends of the back and seat portion.

Abstract: A chair adapted to be stacked is provided, of the type having a rear frame (2) including two rear uprights (3) and rear crosspieces (5), a front frame (7) including two front uprights (8) and front crosspieces (9), a seat (10) and lateral crossbars (11) connecting the rear uprights (3) with the front uprights (8), the chair further having shaped close-fit regions (13) formed in at least one of the frames (2, 7) to removably engage, by close fitting, an underlying chair in a stacked position and the engagement taking place by forced and elastic deformation of the frames (2, 7) at the shaped close-fit regions (13).

Abstract: A furniture construction includes a frame structure made up of a pair of spaced frame sections connected together, and a furniture component mounted to the frame structure. Each frame section includes a lower base section, an upright, and a furniture component support member extending from the upright and to which the furniture component is mounted. The frame sections are preferably C-shaped when viewed from the side. In one form, the furniture component is a seat mounted to the furniture component support, and the frame structure includes a back support area extending upwardly from the seat. A back is mounted to the back support area. In another form, the furniture component is a desk or table top mounted to the furniture component support. Combination desk/chair units may also be constructed utilizing the same basic frame structure.

Abstract: A ready-to-assemble (RTA) furniture system includes a collection of identically configured side panels, with sets of the side panels having different aesthetic and/or functional features, a collection of base panels and back panels spanning between pairs of side panels, the collection of base and back panels being provided in different sets of lengths and configurations to permit construction of different types of furniture. The panels are interconnected through a series of slots and notches. A locking member is provided that can be wedged into a slot to lock the entire RTA furniture item together. A second locking member can be provided to be wedged into a slot in the back panel to provide additional support for a base panel. A wide variety of furniture items are show that can be constructed using the two locking members.
