IPC: B62D25/12
Filed: 1992-02-27
Abstract: PURPOSE:To reduce the number of parts for a component member related to opening and closing an engine hood. CONSTITUTION:In a lift-up engine hood mounted on a frame in such a manner as to be pivotable through a hinge 4, a stay 11 comprising a plate spring is rotatably installed on a hood side hinge member 6. At the time of opening the hood main body 1, the stay 11 has the rear end part 11b locked on the stopper face 15 of a frame side hinge member 5 and the lower surface of the hood side hinge member 6 to hold the hood main body 1 in the open position. At the time of closing the hood, the stay 11 has the rear end part 11b brought into contact with the stopper face 14 of the frame side hinge member 5 and the front end part 11c pressed by the lower surface of the hood side hinge member 6 to be elastically deformed, so that a spring function for pushing up the hood main body 1 for a designated amount at the time of releasing the hood lock is applied to the stay. Thus, the need of a spring for pushing up the hood main body 1 is eliminated so as to reduce the number of parts.

Filed: 1982-05-13
Abstract: PURPOSE:To make the distribution of surface temp. uniform and to reduce the time for warming up by disposing a plate heat element and a heat insulating material successively in lamination on the inside of a heating roll. CONSTITUTION:A roll 1 is constituted of a hollow cylindrical metallic mandrel 2, a release layer 3 of ''Teflon'' or the like coated at a specified thickness on the outside circumferential surface of the mandrel, a plate heat element 4 adhered tightly over the entire inside circumferential surface of said mandrel 2, and a heat insulating material 5 stuck on the inside circumferential surface of the insulating material. When a copying machine is set in the standby state for operation, the element 4 is conducted with electricity, and the heating roll 1 is heated to a prescribed temp. The heat generated by the element 4 in this stage is transmitted thermally to the layer 3 through the mandrel 2 which is a good heat conductor; therefore, the layer 3 is heated to a required fixable temp. within a short time since the machine is set in the standby state for operation. Since the element 4 is adhered tightly over the entire circumferential surface of the mandrel 2, the mandrel 2 is heated uniformly over the entire circumferential surface and the temp. is distributed uniformly in the layer 3.
