摘要： PURPOSE:To dispense with a device retreating door safety shoes immediately before doors are fully closed by forming the safety shoes provided on both door panels of double opening doors into taper shapes overlapped together when the doors are closed. CONSTITUTION:Safety shoes 3, 4 are fitted to door panels 1, 2 via links 5, 6. The safety shoes 3, 4 are normally protruded from the door panels 1, 2, and the safety shoes are formed into taper shapes at their tips to be overlapped together when doors are closed. If obstacles collide with the safety shoes 3, 4 when the doors are closed, the shoes 3, 4 are retreated in parallel with the faces of the door panels 1, 2 via the links 5, 6. When the links 5, 6 are operated, contact points of microswitches provided adjacently are closed, and the doors are reversely rotated. A pinch accident of the elevator door is thus prevented.

摘要： PROBLEM TO BE SOLVED: To perform an operation for connection between a side plate and a car floor efficiently using an inexpensive baseboard and improve a decorative metal fitting mounting operation and designing property. SOLUTION: This car is formed so that a side plate mounting part 1a projecting toward this as viewed from the inside of the car is installed on the upper part of a baseboard 1 fixed to the peripheral edge part of a car floor 2 and a side plate 4 installed on the side plate mounting part 1a is fixedly tightened to the side plate mounting part 1a with bolts 3. Accordingly, by using a simple- shaped inexpensive baseboard 1, the operation for connection between the side plate 4 and the car floor 2 can be performed surely from the inside of the car. In addition, a decorative metal fitting 5 is provided between the lower end part of the side plate 4 and the car floor 2, and the decorative metal fitting 5 is attracted magnetically to the baseboard 1 through a permanent magnet 12. Since flat countersunk head screws for mounting the decorative metal fitting 5 are not required, an operating efficiency at the time of assembly is increased and also the designing property can be increased.

摘要： PROBLEM TO BE SOLVED: To improve the productivity and assembly workability of parts by forming a floor frame which is a strength member in U-shape, engaging the floor plurally divided in a depth direction with the inside of the floor frame and fixing by a bolt at only the lower side of the floor frame. SOLUTION: In the floor structure of an elevator, the floor 1 plurally divided in a depth direction is engaged with the inside of the floor frame 2 which is a strength member formed in a U-shape provided on both sides of an opening direction. The floor 1 plurally divided in a depth direction is tightened strongly by a bolt in the depth direction respectively and this tightened floor 1 is engaged with the inside of the floor frame 2. This engaged floor 1 is tightened strongly by the bolt 3 at only the lower side of the floor frame 2. The number of bolt can be reduced, as the bolt 3 is used only at the lower side for tightening of the floor 1 plurally divided in the depth direction with the floor frame 2.

摘要： PROBLEM TO BE SOLVED: To provide an elevator device in which a rope slip-out preventing member is easily fitted, adjusting operation is easy, and the number of parts is a few. SOLUTION: This elevator device is provided with a slip-out preventing member 11 extending from a member supporting both sides of a pulley shaft 10 on the rope wrapping side, and formed into a U-shape so as to cover the wrapping face, and the slip-out preventing member 11 is provided with slotted holes long in the slip-out preventing space regulating direction, as fitting holes to the supporting member 9 of a pulley. In this case, at fixing the rope slip-out preventing plate 11, when bolts 14 are temporarily fitted, the degree of freedom of the rope slip-out preventing plate 11 is only in the direction of slip-out preventing space regulation, and hence positioning becomes easy. At assembling a balancing weight, the rope slip-out preventing plate 11 is temporarily fixed so that the slip-out preventing space becomes wide, and after a rope 5 is wrapped on the pulley 1, the bolts 14 are loosened to regulate the slip-out preventing space. At fixing again, by fastening either of the bolts 14, it can be positioned.
