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.
摘要:
Pair of engagement chains (100) whose buckling strength is improved, which realizes stable forward and backward driving for a work without requiring to install an auxiliary guide means for suppressing buckling and inclination of the engagement chains (100) and whose backlash prone is eliminated. The pair of engagement chains (100) has inner tooth plates (110), bushes (120), outer tooth plates (140) and connecting pins (150) and is integrated by engaging hook portions of the inner tooth plates (110) and hook portions of the outer tooth plates (140), respectively, and is branched by disengaging the hook portions of the inner tooth plates (110) and the hook portions of the outer tooth plates (140), respectively. The pair of engagement chains (100) further includes inflection restricted plates (170) having inflection restricted surfaces (171) and inflection restricting plates (180) having inflection restricting portions (181) that are connected on the both ends of the connecting pins (150).

摘要:
The present invention is an improved apparatus and method for forming a retractable tower or column. The present invention includes pointed hooks wherein the hooks are attached to each section of a section chain, one in a horizontal direction and one in an off-set manner. The section chains are placed on a take up mechanism in an operable position and then raised utilizing a motor. As the section chains are raised, they are guided by a guide tower, rollers, shims, and gear racks into a position whereby hooks from adjacent sections of the section chains form coupled engagements. The coupled engagement of the hooks of the sections of each adjacent section chains thereby form the column.
