[0005] But, in above-mentioned elevator equipment, because it offers the opening part that is specially used for arranging hoisting machine on hoisting passage wall specially in order to arrange hoisting machine, so can cause the strength of the hoisting passage wall of this part to be insufficient, thereby need the opening part Take special reinforcement measures around
In addition, in order to maintain the hoist, it is necessary to install a maintenance door leading to the outside of the hoistway, a passage leading to the maintenance door, and a space for maintenance of the hoist, etc. There are design arrangements around the hoistway. Constraints and cost-increasing issues

Embodiment Construction
[0032] Hereinafter, embodiments of the elevator equipment according to the present invention will be described with reference to the drawings.
[0033] Such as figure 1 and figure 2 As shown, the elevator installation has: an elevator car 2 that moves up and down in the hoistway 1; a counterweight 3 that is balanced with the weight of the elevator car 2 and lifts in the opposite direction to the elevator car 2; guides the elevator car The elevator car guide rails 4a, 4b for lifting the car 2; the counterweight guide rails 5a, 5b for guiding the counterweight 3 to ascend and descend; the main sling 6 for suspending the elevator car 2 and the counterweight 3; Thin winch 7 of the bottom inside. A convex portion is formed on the hoistway wall 8, and the convex portion is formed by, for example, a beam 9a of the building erected at the lowest position of the hoistway 1 and a beam 9b erected at a position higher than the beam 9a by a predetermined dimension. Moreover, the guide ...

The invention provides an elevator device, in which no special space is formed on the wall of an elevating channel for arranging a hoister, so as to save the space. The elevator device comprises an elevator car (2) elevating in the elevating channel (1), a balance weight being in balance with the weight of the elevator car and elevating in the direction opposite to the elevating direction of the elevator car, a guide rail guiding the elevator car and the balance weight to elevate, a main suspension cable (6) suspending the elevator car and the balance weight, and the hoister (7) configured at the lower part or the upper part in the elevating channel. A protruding part projected to the side of the elevator car, such as a beam (9a,9b) and the like, is formed on the wall (8) of the elevating channel, in the elevator device, the hoister is supported in a gap between the protruding parts, namely between the beam (9a) and the beam (9b) by supporting members (11a,11b), a rope wheel (76) of the hoister is arranged close to the side of the elevator car, and a main body of the hoister is arranged close to the side of the wall of the elevating channel.
Description
technical field [0001] The present invention relates to a so-called machine-room-less elevator installation that does not have a machine room. Background technique [0002] As an elevator device without a machine room, that is, a so-called machine room-free type, it has been disclosed that the hoisting machine is arranged inside the wall of the hoistway, and only the traction pulley is arranged between the elevator car and the wall of the hoistway. A space-saving solution (for example, refer to Patent Document 1). [0003] In addition, in general elevator equipment, when there are concave and convex parts on the wall of the elevator passage due to the existence of the beams of the building and the columns erected in the elevator passage, the effective size of the equipment that can be installed in the elevator passage is generally the innermost That is, the convex portion closest to the elevator car side is used as a reference. [0004] Patent Document 1: Japanese Patent N...
