Abstract: PROBLEM TO BE SOLVED: To reduce the motive power by forming a sandwich panel or a hollow section panel as a structural member of a cage. SOLUTION: A cage 1 of an elevator is formed by five faces, that is, a floor plate 3, a ceiling plate 4, the side plates 5 and a back plate 6, and an openable and closable car door 7 is installed at a front side. The floor plate 3, the ceiling plate 4 and the side plates 5 are formed by a sandwich panel comprising a core material and a skin material made of a plastic sheet, or a hollow section panel using the plastic sheet as the skin material and the stringer, and a part corresponding to a car frame 2 is provided with a reinforcement spur made of these panels to improve the total rigidity and strength of the cage. Accordingly high rigidity and strength can be obtained even when a thickness of the panel is thin, and the weight can be considerably reduced by the effect of the low specific gravity of the material. Whereby the motive power can be reduced, and the car can be easily applied to a home elevator operated by a domestic power source.

Abstract: PROBLEM TO BE SOLVED: To improve the structure of a side rail part by setting the cross section of the side rail to a solid closed section structure of an FRP material including a skin material and a core material and changing in the front/rear direction of a truck. SOLUTION: A gate panel 9 opening/closing balancer 41 is fixed to the bottom side of a floor body, the inside face of a side rail 22, or a lateral floor joist and the tip part of its operation rod 42 is rotatably coupled with the gate panel 9 via a coupling member 43. When the panel 9 fitted to the side rail 22 so as to open/close freely is opened, the balancer 41 energizes upward (closed direction) so as to substantially offsets its dead load and operate the panel 9 lightly and easily. The cross section of the side rail 22 of the balancer 41 fitting part has an L-shaped open cross section structure 44 and is provided with an L-shaped FRP material part 45 and a metal reinforcing member 46 embedded therein so as to be insert formed. As a result, this constitution allows the balancer 41 to be fitted easily even in a case of positioned inside the side rail under the floor limited spatially and sufficiently secure the rigidity and durability necessary for respective parts, while securing the light weight performance due to the use of the FRP material.

Abstract: PROBLEM TO BE SOLVED: To provide a high rigidity, a high strength, a reduced weight, and a reduced power requirement by employing an FRP sheet having a specific value of vibration damping coefficient ratio as a component of a cage. SOLUTION: A cage 2 comprises as components; side panels 5, 6, a ceiling panel 7, a back panel 8, a floor panel 9, and a door 10. At least some of the components are made of materials including an FRP sheet. Vibration damping coefficient ratios of the components including the FRP sheet is made to be at least 0.002, or the vibration damping coefficient ratio of the entire cage 2 is made to be at least 0.005. While the higher the vibration damping coefficient ratio, the better the vibration damping property, too high a damping coefficient ratio causes a steep increase in manufacturing cost. Therefore, the abovevalues are appropriate.

Abstract: PURPOSE:To shorten the time for providing precursor fiber with flame resistance, by flattening a precursur fiber assembly to be provided with flame resistance followed by treatment on heating at a specific flattened state. CONSTITUTION:A precursor fiber assembly is flattened using e.g. a free roll, and made to travel through the heating medium fluidized bed 5 in an oven 1 for provision with flame resistance with the width W direction of the flattened fiber bundle essentially vertical whereas the thickness d direction horizontal, thus performing provision of said fiber with flame resistance so that the ratio W/d is >=5. During the above process, fluidization of the heating medium is little hampered, thus accomplishing high heat transfer from said medium to the flattened fiber bundle.
