Abstract: A man-powered braking apparatus which uses rocking motion to switch over between the braking state and the releasing state, assures smooth operation, and minimizes the reduction in braking force when the braking lever is returned. When the force to the braking lever 20 is removed, the braking state in which the pawl member 40 is engaged with the ratchet plate 12 is maintained. When the force is removed, the power transmission pin 25 is moved, being kept fitted into the cam groove 52 in the transmission link member 50, and is shifted from the force transmission cam groove 53 to the release holding cam groove 54, the transmission link member 50 being turned to the releasing position, and the pawl member 40 is brought into the state in which it is energized in the direction for being disengaged from the ratchet plate 12 while the braking state being maintained.

Abstract: A parking brake apparatus for activating a brake unit includes a base member; an operating lever supported on the base member for generating an operating force when the operating lever is operated so that the operating force is transmitted to the brake unit through a brake cable; an inputting member to be rotated with the operating lever; an intermediating member disposed separately from the inputting member for interconnecting the inputting member and the brake cable; and a connection member for connecting the intermediating member and the inputting member. Accordingly, the intermediating member transmits the operating force to the brake cable from the connection member.

Abstract: A cane type emergency brake of an automobile having a handle which can turn freely over 180 degrees, and which is of durable function. The cane type emergency brake includes a stem (10) which can be held in a state of pulling a brake cable, a handle (20) combined free-rotatably to the stem (10), a return mechanism (30) for returning the handle (20) to an initial position, and a free turn stopper (40) for disabling the free turning of the handle (20). The return mechanism (30) includes a cam plate (31) and a cam (33). The cam plate (31) is pressed to the periphery of the cam (33). The cam (33) is formed monolithically on the enlarged top (15) of the stem (10) and slides the cam plate (31) against the force that presses the cam plate (31) to the periphery of the cam (33). When the handle (20) is in the initial position, the contact position where the cam (33) and the cam plate (31) are contacted with each other is shifted from the center line of the stem (10) to the direction of the force.

Abstract: A belt conveyor having two rollers supported at opposite ends of a support frame and a belt stretched between the rollers, in which a cylinder having an operating rod reciprocatable in a moving direction of the belt is mounted on the support frame; a drum including a one way clutch mechanism therein and having a sprocket wheel fixed therearound is fitted around a transmission shaft integral with one of the rollers; a chain is wound around the sprocket wheel mounted around the drum including the one way clutch mechanism therein; and the chain is connected to the operating rod of the cylinder.When the operating rod of the cylinder reciprocates, the chain is reciprocated by the operating rod. This reciprocatingly rotates the sprocket wheel mounted on the drum in which the one way clutch mechanism is installed. The rotation in a predetermined direction is transmitted, through the one way clutch mechanism, to the transmission shaft of the roller around which the belt is wound.
