摘要:
In the conventional X-linked lift mechanism, in the state where the lift frame is lowered, lift drive components occupy a wide area. Therefore, it is difficult to additionally dispose other functional mechanism components. Further, in the configuration wherein the lift frame is raised when the linear actuator acts in the direction to shorten itself, if the linear actuator is broken, the lift frame may drop dangerously.The present invention solves the abovementioned problems by an X-linked lift mechanism having first links 3 and second links 4 constituting an X-linked mechanism between a base frame 1 and a lift frame 2, wherein a drive member 11 pivotally rotatably installed between the other lateral side portions of the second links is connected with boost arms 12 and a drive arm 13; guide members 15 for guiding the moving members 14 installed at the ends of the boost arms are installed on the other lateral side portions of the first links in the length direction; and a linear actuator is provided to extend between the other lateral side of the first links and the drive arm.

A support mechanism in which one end of a knee bottom section (2) is supported on a bed frame (1) in such a manner that the knee bottom section can be pivotally raised and lowered. Also, one end of a leg bottom section (6) is pivotally rotatably connected with the other end of the knee bottom section, a support stay (7) is pivotally rotatably connected with the underside of the other end of the leg bottom section, and a support device (11) of a support portion (9) provided at the opposite tip of the support stay is provided on the bed frame. The support device includes a guide portion (12) and an engaging portion (13) for movably supporting the support portion of the support stay. The guide portion can support the support portion moved in relation with the pivotal rotation of the knee bottom section within the entire pivotal rotation range of the knee bottom section. The engaging portion is provided above or below a vacant portion adjacent to the end portion of the guide portion on which the support portion is located when the knee bottom section is pivotally lowered.
摘要:
In the conventional support mechanism capable of supporting the distal end of the leg bottom section at either a high position or a low position in the state where the knee bottom section is pivotally raised, the distal end of the leg bottom section that is set at the high position can be shifted to the low position only in the state where the knee bottom section is kept pivotally raised. If the knee bottom section is pivotally lowered in the state where the distal end of the leg bottom section is set at the low position, the distal end of the leg bottom section is forcedly released from the mechanical engagement for the low position and shifted to the mechanical engagement for the high position.The present invention solves the abovementioned problem by a support mechanism, characterized in that one end of a knee bottom section 2 is supported on a bed frame 1 in such a manner that the knee bottom section can be pivotally raised and lowered, that one end of a leg bottom section 6 is pivotally rotatably connected with the other end of the knee bottom section, that a support stay 7 is pivotally rotatably connected with the underside of the other end of the leg bottom section, that a support means 11 of the support portion 9 provided at the opposite tip of the support stay is provided on the bed frame, that the support means consists of a guide portion 12 and an engaging portion 13 for movably supporting the support portion of the support stay, that said guide portion can support said support portion moved in relation with the pivotal rotation of the knee bottom section within the entire pivotal rotation range of the knee bottom section, and that the engaging portion is provided above or below the vacant portion adjacent to the end portion of the guide portion on which the support portion is located when the knee bottom section is pivotally lowered.
摘要:
A tubular flame burner, a combustion method, and combustion controller, are disclosed. Here, the tubular flame burner comprises: a tubular combustion chamber whose h one end is open; fuel-spraying nozzles and oxygen-containing-gas spraying nozzles. The respective nozzle orifices are formed in the inner face of the combustion chamber so that each spraying direction is in a neighborhood of a tangential direction of the inner circumferential wall of the combustion chamber. And an ignition device is disposed at a position r/2 from the tube axis of the combustion chamber (r: the radius of the combustion chamber). The length of the combustion chamber can be adjusted, the tubular flame burner is a multi-stage burner formed of multiple tubular flame burners, and a gap between the inner tube and the outer tube serves as a gas-flow path. A combustion control method for the tubular flame burner is disclosed, wherein on/off of switching valves is controlled so that the spraying speed from each nozzle is maintained in a predetermined range corresponding to the combustion load.

A composition for a wire coating member having flame retardancy that is heat resistant and productive without using electron irradiation crosslinking, and an insulated wire and a wiring harness having the same. The insulated wire includes a wire coating member containing the composition for the wire coating member that contains water-crosslinkable polyolefin containing polyolefin that is modified by a silane coupling agent, unmodified polyolefin, modified polyolefin that is modified by a functional group, a bromine flame retardant, a cross-linking catalyst, a phenolic antioxidant, and either one of a zinc sulfide, and a zinc oxide and an imidazole compound. The insulated wire is prepared by extrusion-coating a conductor with the composition to form the wire coating member around the conductor, and the wire coating member is water-crosslinked.
