Title: Door assemblies
IPC: E05F15/16
Filed: 1971-02-18
Abstract: 1377503 Door operating mechanism WESTLAND ENGS Ltd 13 April 1972 [18 Feb 1971] 4913/71 Heading E2M A door assembly includes a door 11 which may be operated manually or by a power driven mechanism comprising an endless flexible member, such as a chain 25, around two rotary members, such as sprockets 23, 24, at least one of which is driven by a uni-directional rotating motor, and having means engageable with a carriage 27 which is movable on a guide track 22 and is connected by a link 29 to the door. The carriage 27, Fig. 3, includes a plate 35 against which a plate 40 is biased by cup washers 45, and this plate 40 carries four pins 43, 44 (two only shown) arranged at the corners of a square, which pass through holes in the plate 35 and terminate short of a central plate 32 of the carriage, one pair of diagonally opposite pins being shorter than the other pair. The sprocket 24 is driven by a uni-directional electric motor 26, and when this moves the chain (the door being closed), a bobbin 46 carried by the chain engages the shorter pin 44, exerting sufficient force to move the plate 40 away from the plate 35 so that the bobbin passes the pin 44 but not the longer pin 43, so that it moves the carriage from left to right, Fig. 1, opening the door. When the carriage reaches the end of the track 22 it encounters a stop and actuates a limit switch (57), Fig. 4 (not shown) to switch off the motor. When the motor is switched on again, since the carriage is held by the stop the bobbin 46 passes the pin 43, passes around the sprocket and is trapped by the other pair of pins, moving the carriage in the opposite direction to close the door. Should the door encounter during opening or closing a sufriicien obstruction, the bobbin will break free of the pins and move around the sprocket to reverse the door motion. An alternative embodiment 86 of the carriage. Fig. 11, comprises two spaced plates 92, 93 one on either side of a track 82 having spindles 100 engaging in a slot 98 of a further plate 97. When the motor is switched on the top part of chain 83 moves from right to left and bobbin 103 on the. chain engages pin 95 to move the carriage to the left. When the. plate 97 encounters stop 90, it is held, enabling the bobbin to escape past sloping surface 101; a further bobbin on the chain contacts a limit switch to switch off the motor. When the motor is switched on again the bobbin 103 is carried until it encounters pin 96 to move the carriage in the opposite direction. The motor may be switched on by a key post, pressure pad, photoelectric cell or radio receiver and the current supply is then maintained by a latching relay (51), Fig. 4 (not shown) until switched off by limit switch (57). The door may be of the up-and-over kind, Fig. 1, or may be sliding, Fig. 10 (not shown), and may be secured against manual operation by a bolt (104) or by latches (58), Fig. 5 (not shown) which can be overriden by the power driven mechanism.

Abstract: 1490911 Full-face disc brakes; slack-adjusting T CAMPAGNOLO 5 Feb 1975 [5 Feb 1974 7 June 1974] 4920/75 Heading F2E A whoel hub and disc brake assembly especially for a motor cycle comprises a brake disc 7, Fig. 1, and a non-rotatable brake plate 10 located laterally of the hub 1; the braking surface 20 of the brake disc 7 is a frusto-conical surface coaxial with the wheel axis; the brake plate has either a single friction pad 17 having a correspondingly frusto-conical surface, or a series of pads each in the form of a segment of such a surface; the brake plate 10 is slidable along the wheel axis under the action of fluid pressure applied, e.g. between an annular piston 22 and its surrounding cylindrical cavity for brake engagement, and under the action of a resilient component, e.g. spring 26, for brake release. As shown in Fig. 1, slack-adjustment may be effected manually by a series of threaded pins 29 each having a lock nut 30. In Fig. 3 the radially outer part of disc 107 is formed symmetrically with a pair of frustoconical braking surfaces 120, and two brake plates 110 are provided. Here, spring brake release devices are combined with automatic slack adjusters, 200. A headed pin 201, Fig. 6, is retained in a radial extension 131 of a bush flange 13 by a brake release spring 205, normal brake clearance being determined by the distance between pin head 202 and the edge of a ring nut 203, such distance being adjustable by a screw 210 contacting head 202. The shank of the pin is a tight fit in a further spring 208 retained in a cavity in the brake plate. During brake application after excessive wear, pin head 202 first contacts ring nut 203, after which continuing hydraulic pressure forces plate 10 to slide spring 208 along the pin shank to a new position. On brake release, spring 208 holds fast on the pin, while spring 205 returns the pin until head 202 contacts screw 210. The brake disc braking surface is machined smooth, or provided by an inserted smooth ring 20 or 120. In the upper part of Figs. 1, 3, two perforated flanges for spokes are provided, while in the lower part a disc D extends to a tyre rim C. Provision may be made for cooling (Fig. 5, not shown).
