摘要： PURPOSE:To secure the effective inner size of an elevator cage as well as to prevent any malfunction of a destination floor button and made operability of this button so better by attaching a faceplate to an interspace between cage side plates so as not to project a cage control panel from each surface of these cage side plates. CONSTITUTION:A cage control panel 4 is attached to an interspace between side plates 1a and 1b halved up and down, and a faceplate 3 of this control panel 4 is installed as being tilted to these cage side plates 1a, 1b. With this setup, the faceplate 3 and a destination button 2 attached thereto both are made unprojected from each surface of these cage side plates 1a, 1b, thereby securing an effective inner size of the cage, and if a person leans against the side plate, any touch on the destination floor button 2 is avoided, thus any malfunction of this button 2 is preventable.

摘要： PURPOSE:To improve the working property of side plate formation at both direction sides by setting the height direction size of a handrail frame to the same at that of an operating panel, and installing those of handrail frame and operating panel in space between side plates halved up and down at the same intermediate part. CONSTITUTION:Height direction size of a handrail frame 4 in an elevator cage is set to the same as that of an operating panel 2. In addition, this handrail frame 4 and the operating panel 2 are installed in space between side plates (1a and 1b), (1c and 1d) halved up and down at the same intermediate part. With this setup, it will do that these vertical side plates 1a-1d at left and right are all produced in the same size, so that side plate formation at both sides comes easy enough, thus the working propery of this side plate formation at both sides is improvable.

摘要： PURPOSE:To prevent a child from going to a rooftop alone when the uppermost floor is the rooftop floor and secure safety by connecting a selector switch in series to the destination floor button circuit of a specific floor in the car of an elevator for an individual house. CONSTITUTION:In the case of a four-storied building, a selector switch A is provided on the destination floor button of the rooftop floor in the destination floor buttons 1-R of the first floor through the rooftop floor. When the selector switch A is set to the stop position, the destination floor button R of the rooftop floor is disabled even if it is pushed. When the selector switch A is set to the operation position, the destination floor button R of the rooftop floor is enabled, and the operation to the rooftop floor is allowed. The switching of the floor operation can be made in a car to prevent a child from going to the rooftop floor (uppermost floor) alone, the operability is improved, and the safety is secured.

摘要： PURPOSE:To provide an elevator cage which is reduced in the manufacturing cost and prevents a passenger from feeling psychologically uneasy by protruding the upper parts of the two side plates of an elevator cage outwardly from the lower parts thereof. CONSTITUTION:Since, in an elevator cage, lower and upper side plates 3 and 7 are commonly used as side plates on both sides, a manufacturing cost is reduced. The upper side plate 7 is protruded outwardly from the lower side plate 3. Since a distance between the upper side plates 7, i.e., an upper width Wu, is higher than a distance between the lower side plates 3, i.e., a lower width Wl, an upper space located in the vicinity of vision and within the working range of a hand can be increased, whereby a passenger is prevented from feeling psychrologically uneasy. Further, both side plates comprise the lower side plate 3, the upper side plate 7, and intermediate members 8a and 8b, and a side plate constituting part is small, whereby the side plates can be easily processed, resulting in facilitation of manufacture.

摘要： PURPOSE:To prevent fire of an elevator or a building by detecting the malfunction of a capacitor by a circuit breaker connected to the capacitor to turn OFF a main circuit breaker. CONSTITUTION:A main power source is turned ON and a main circuit breaker MCB is closed to turn ON an upward contactor 11 or a downward contactor 12, thereby operating an elevator. However, if a capacitor C for controlling a motor M is deteriorated in its insulation due to an abnormal heat generation, it protection is required. That is, an electromagnetic coil in the breaker CB connected in series with the capacitor C senses the malfunction to turn OFF the breaker CB. Then, the auxiliary contact CA of the breaker CB connected to the tripping coil SHT circuit of the breaker MCB is turned ON to automatically break the breaker MCB, thereby stopping the elevator. Accordingly, it can prevent the capacitor C from deteriorating in the insulation.

摘要： PROBLEM TO BE SOLVED: To simplify surrounding circuits by employing an elevator position detector comprising a lead switch and a permanent magnet. SOLUTION: When there is no dead contact of a deceleration starting relay, a lead switch 1 and a dead contact 5b of the deceleration starting relay are connected in parallel by using the position detector, and a circuit connected in series with a contactor coil 6 is driven by another power supply. When the deceleration starting relay is turned ON, a deceleration starting contact 5b isturned OFF. When an elevator approaches a destination floor from a stand-by state, a guide plate bites at the position detector, and the lead switch 1 is turned OFF, the contactor coil 6 for stopping is turned OFF to stop the elevator. In this manner, the function of the position detector before replacement can be maintained.

摘要： PROBLEM TO BE SOLVED: To use a position detector under the inclusion of a one having b- contact function, reduce cost and improve case of handling by providing the contact of a reed switch between the gate and cathode of a thyristor, and forming a circuit for conducting the thyristor when the contact of the reed switch is closed. SOLUTION: A partial voltage resistor R1 and diodes D1, D2 are serially connected between the anode and gate of a thyristor SCR1 on a base, and a resistor R2 is connected between the gate and cathode of the thyristor SCR1. A reed switch 1 is connected between the resistor R1 and the cathode of the thyristor SCR1 or the like through a lead wire, whereby a position-detecting circuit A is formed. Since the reed switch is opened when a shielding plate is bitten into, the current is carried to a terminal 5 → the resistor R1 → the diodes D1, D2 → the gate of the thyristor SCR1, the thyristor SCR1 is turned ON, and a relay RY1 is turned ON last. Therefore, since the relay of a load is turned ON in the operation of the position detector, a-contact function can be provided.

摘要： PROBLEM TO BE SOLVED: To reduce the hoistway flat space of an elevator by fixing members attached to the ends of left and right steel tower horizontal girders to the building structure of a deep direction disposed to face the same at right angles. SOLUTION: A horizontal girder 10 is connected to a steel tower pillar 3. A member 26 is formed in an L shape, its vertical surface is fixed to the horizontal girder 10 by a bolt, a fixing hole is formed to be a long hole 26a to be adjusted in a front/rear direction and the other vertical surface is fixed to a large beam 23 under each floor of the building of a deep direction. By fixing a steel tower to the large beam 23 of the building structure of a deep direction via the L-shaped member 26, twisting is prevented during assembling of the steep tower and the horizontal girder of the steel tower is made unnecessary. Thus, space is conserved for an elevator hoistway, the degree of freedom is increased and an efficient building is provided.

摘要： PURPOSE:To improve design work as well as making the size of a viewing window, provided at a door, large enough to see the whole area around the floor in a car in accordance with the original purpose. CONSTITUTION:The fulcrum pin 12 of a lead wire guide support body 11 is placed above a viewing window 8, at the second door 6 side end of the first door 5 of a car, and the lead wire guide support body 11 rotatably fitted to the fulcrum pin 12 is engagedly supported by a guide support body guide element 13 disposed at the door pocket side end of the second door 6. A lead wire 10 from a safety device 9 is then pulled out as far as the outside of the door pocket side end of the second door 6 by the lead wire guide support body 11. The lead wire is thereby guided into an invisible position in the viewing window even in the case of the door being opened.
