摘要:
Chain detachment and chain entry are avoided, and a process for setting the length of a meshing chain is avoided, while the chain feed length can also be freely changed. A meshing chain stopper (190L) comprises a meshing chain stopper attachment part (191) and a contact-stop protrusion (192). The contact-stop protrusion (192) is contact-stopped at a contact-stop point (173A) provided on the periphery of a chain locus (L) when a pair of meshing chains (150, 150) are being driven.

Provided is an interlocking chain unit that has reliable and strong interlocking and avoids buckling, breaking, and bending of a rigidified chain portion. In the interlocking chain unit (100), the interlocking operation of an outer tooth link plate (112BZ) and an outer tooth link plate (112AY) that are just about to complete the interlocking operation is completed in a manner that causes a first inter-pin distance (d1) and a second inter-pin distance (d2) become substantially equal to each other, and causes a third inter-pin distance (d3) to approach the second inter-pin distance (d2).

Provided is an interlocking chain unit configured such that chains reliably and firmly engage with each other and that the buckling and twisting of a rigidified chain portion are avoided. An interlocking chain unit (100) is configured such that the outer edges of a plate overlap region (P) are defined by contact portion faces (111aa, 111aa) and flat buckling restricting end faces (112b, 112b), and that the plate overlap region (P) is constructed from the outlines of two plate overlap portions (Pa, Pa) which are point-point-symmetric about the point (C) of intersection between hook-shaped interlocking end faces (111a, 111a) and the buckling restricting end faces (112b, 112b).

An interlocking chain type forward and backward actuating device is provided that does not increase workload involved in assembling the device, adjusting the rotation phase, and servicing and maintaining the device. The device is capable of smoothly actuating a driven body by advancing and retracting the body, and of preventing any pulsation or the like of the meshing chain. The interlocking chain type forward and backward actuating device (100) includes chain-guide grooves (131) formed so as to equalize an interlocked-state pin-to-pin distance (D1) between a pair of connecting pins (110, 110) that face each other in a chain interlocking imaginary plane (S) and a rigid-state pin-to-pin distance (D2) between a pair of connecting pins (113, 113).

In order to stably drive a body to be driven such as a lifting table, an engagement chain type device (100) for forward and backward movement is configured in such a manner that a pair of engagement chains (110, 110) has rigid chain portions (110D). The rigid chain portions (110D) are configured in such a manner that, within a predetermined range from the front ends of the chains in the direction in which the pair of engagement chains (110, 110) is rigid, inner tooth plates (111) are constantly engaged with each other and outer tooth plates (112) are constantly engaged with each other. Square column-shaped reinforcement core members (140) fitted in the square column-shaped hollow sections (S) of the rigid chain portions (110D) are connected to mounting members (C).

Provided is an interlocking chain forward and backward actuating device type device, the device being configured so that the space within the device is effectively utilized and that a device configuration most suitable for driving interlocking chains is selected to enable the interlocking chains to be smoothly driven. An interlocking chain type forward and backward actuating device (100) is configured in such a manner that a pair of flat face-shaped chain support faces (132AS, 132AS) which sandwich and support a rigid chain portion (110G) from both sides thereof each form a portion of each of the guide groove faces (132, 132) of chain guide grooves (131, 131) while being continuously connected to each of a pair of curved guide faces (132BS, 132BS) which respectively guide disengaged portions (110H, 110H) of a pair of interlocking chains (110, 110), the disengaged portions (110H, 110H) having been disengaged from each other.
