Embodiment Construction

[0016] exist figure 1 An elevator 20 having an elevator car 22 movable through a shaft is illustrated in FIG. Machine 24 drives car 22 in combination with counterweight 28 . The machine 24 is mounted on a deck 26 . The deck 26 is mounted on a pair of spaced rails 42 for guiding the cab 22 and for guiding the counterweight 28 (see figure 2 ) Between another pair of spaced guide rails 43. Rails 42 and 43 are typically provided by separate rail elements interconnected by a connecting structure such as shown at 45 . One-piece or one-piece rails are also within the scope of the present invention. A pulley 30 associated with machine 24 drives a connection 36 , such as a cable or belt, which also extends around a pulley 34 associated with car 22 and another pulley 32 associated with counterweight 28 .

[0017] The opposite ends of connector 36 are connected to terminal knobs 38 and 40, as is known. As schematically illustrated in this figure, terminal hitches 38 and 40 are on ...

Abstract

An improved elevator mounts its dead end hitches (38A, 38B, 38C and 40A, 40B, 40C) on the bedplate (46, 48) of a machine roomless elevator. The dead end hitches are preferably positioned on an upper surface of the bedplate such that they are easily accessible. Further, the governor (80) is mounted adjacent the machine (24) on the bedplate. Preferably, there are a plurality of dead end hitches and a plurality of connecting members connecting the car and counterweight. The plurality of dead end hitches are preferably aligned along lines (A and B) which are parallel to a drive axis of the drive sheave (30). Further, the plural connecting members are preferably each associated with a surface on a drive sheave and a pair of dead end hitches. A line drawn through a sheave surface and its two associated dead end hitches would be perpendicular to the rotational drive axis.

Description

Background of the invention [0001] The present application relates to an elevator having a machine mounted on a deck and a terminal hitch extending vertically above the lowest surface of the deck. Also, the terminal tacks are aligned in a space efficient manner. [0002] Elevators typically include an elevator car and counterweights connected by several tensioning or connecting members, such as cables or belts. The machine drives the linkage to move the counterweight and the car through the shaft. [0003] In the past, machines were installed above the shaft in a room called the machine room. This requires a lot of additional space. More recently, elevators have been developed that incorporate the machinery in the space between the car and the opposing wall. In this configuration, the machine room is no longer required. Such elevators are commonly referred to as "machine roomless" elevators. [0004] In known types of machine room-less elevators, the machines are mounted...
