    摘要: An object of the present invention is to provide a tensioner with a simple structure that effectively maintains the oil pressure inside an oil pressure chamber at a correct level, while also making the machining and assembling processes less demanding. The tensioner includes a relief mechanism, which includes an orifice member that has an oil passage designed to form an orifice structure. The orifice member has a flat circular end wall part and a circumferential wall part that extends rearwards from the peripheral edge of the end wall part. The circumferential wall part includes a bulged portion that extends rearwards and is curved radially outwards. The bulged portion is designed such that the diameter of the circumscribed circle of the orifice member is greater than the inside diameter of the plunger as viewed in plan from an axial direction before the orifice member is press-fit into the plunger.

    摘要: A wand for a blind assembly comprising (a) an elongated member, (b) a rotatable member located at or adjacent one end thereof, (c) guide member located at or adjacent another end thereof; and (d) a cord having a loop, wherein the loop passes from a position remote from the rotating member, engages the rotating member, passes about the guide member and returns to the remote position after reengagement of the rotating member, wherein the loop adjacent to or within the elongated member is retained between the rotating member and the guide to restrict movement of the loop perpendicularly of the elongated member, and wherein the loop remote from the rotating member is adapted to engage and rotate a drive member of a blind assembly.

    摘要: An object of the present invention is to provide a chain drive device that guides a chain favorably with a chain guide to prevent noise generation and wear or damage of various parts with a simple structure, and to provide the chain guide. Provided is a chain drive device 10 having a guide shoe 40 that includes a shoe surface part 41 and a lip 43. The shoe surface part 41 has a larger widthwise dimension than that of the chain 20. The lip 43 has a front-side lip end 44 which has a lip front end face 44a that faces the front side in the chain running direction. The lip front end face 44a has a height that is set larger than a dimensional difference in backside height between inner plates 21 and outer plates 23.

    摘要: An articulated chain comprises alternate inner and outer chain links interconnected by a chain joint. Each inner chain link comprises at least one chain link plate and each outer chain link comprises at least two chain link plates, and the chain link plates have a structured link plate back that is adapted to be brought into contact with a tensioning or guide rail. The structured link plate back comprises at least one recess having a closed circumference or at least one recess having a circumference that is closed with the exception of an access opening, and is straight or slightly concave in shape for contact with a tensioning or guide rail. A chain drive comprising a driving sprocket, at least one driven sprocket, and at least one tensioning or guide rail and an articulated chain, in contact with the at least one tensioning or guide rail is provided.

    摘要: A chain guide and tensioning apparatus (10) for reducing friction and heat generated by said chain guide and tensioning apparatus (10) engaging a driven chain (16). A guide body (12) has an engagement surface (26) and a first aperture (54) extending through the guide body (12) and opening into the engagement surface (26). A guide face (14) at least partially overlays the engagement surface (26) and has a contact surface (44) configured to guide and tension the driven chain (16). A first recessed groove (46) is formed on the contact surface (44) and is in communication with at least one second aperture (48) extending through the guide face (14). The first aperture (54) is adaptable to receive and communicate oil from an oil source to the second aperture (48) and the first recessed groove (46) for reducing friction and heat from guiding and tensioning the driven chain (16).
