Definitions
- the present invention relates to a machine-room-less elevator apparatus having no machine room.
- EP-A-1018480 discloses an elevator system which can be accommodated within the height of the top floor of a building and in which a hoisting machine can be disposed within the shaft.
- Fig. 11 shows a machine-room-less elevator apparatus having no machine room disclosed in Japanese Unexamined Patent Publication No. 10-139321 .

- reference numeral 3 denotes a car that has two car bottom return sheaves 26 on the bottom thereof, is suspended by a main rope 8 via the car bottom return sheaves 26, and moves up and down in the hoistway 1 by being guided by car rails 4
- reference numeral 6 denotes a counterweight that has a counterweight suspension sheave 27 at its top, is suspended by the main rope 8 via the counterweight suspension sheave 27, and moves up and down in the hoistway 1 by being guided by a counterweight rail
- reference numeral 9 denotes a hoisting machine that is constituted by a sheave 10, on which the main rope 8 is wound, and a motor 11 for driving the sheave 10, and disposed at the top of the hoistway 1 such that the rotating surfaces of the sheave 10 are horizontal and the sheave 10 is
- the main rope 8 has its one end at a first fixing point 28, while it has the other end at a second fixing point 29.
- the main rope 8 is routed, starting at the first fixed point 28, through the counterweight suspension sheave 27 attached to the counterweight 6, the first direction inverting pulley 13 disposed at the top of the hoistway 1, the sheave 10 of the hoisting machine 9, the second direction inverting pulley 14 disposed at the top of the hoistway 1, and the car bottom return sheave 26 disposed on the bottom surface of the car 3, in this sequence, before reaching the second fixing point 29.
- Fig. 12 is a sectional view showing the top portion of the hoistway 1 of a conventional elevator apparatus in Fig. 11 .
- the sectional view shows a frame 31 that is always connected to a pivot arm 30 and has the hoisting machine 9.
- the pivot arm 30 can be circularly moved by a pivot shaft 32 to the position indicated by the dashed line. Therefore, the conventional elevator apparatus has been advantageous in that the hoisting machine 9 can be easily installed, maintained, and repaired.
- the conventional elevator apparatus is constructed to have two to one roping, requiring the two car bottom return sheaves 26 disposed on the bottom surface of the car 3 and also the counterweight suspension sheave 27 disposed on the counterweight 6. This has been interfering with the flexibility of the layout in the hoistway because of the complicated construction.
- the width of the hoistway 1 in the height direction is the sum of the thickness of the hoisting machine 9 and the diameter of the first direction inverting pulley 13 or the second direction inverting pulley 14, thus resulting in a large gap dimension at the top portion of the hoistway 1 above the car 3.
- pivot arm 30 has to be circularly moved to perform maintenance or inspection of the hoisting machine 9, preventing maintenance or inspection from being easily accomplished.
- the present invention has been made toward solving the problems described above, and it is an object of the invention to provide an elevator apparatus that permits space saving in a hoistway and also easy maintenance and inspection.

- the brake 12 is installed such that it also faces downward as in the case of the motor 11.
- Reference numeral 13 denotes a first direction inverting pulley disposed at the top portion of the hoistway 1
- reference numeral 14 denotes a second direction inverting pulley disposed at the top portion of the hoistway
- reference numeral 15 denotes a hoisting machine assembly that is constructed of a planar base 16 serving as a bottom surface and an edge portion 17 with both ends formed into a U shape, supported by the car rail 4 and the counterweight rail 7, and on which the hoisting machine 9 and the first direction inverting pulley 13 and the second direction inverting pulley 14 are installed

- reference numeral 22 denotes a second opening provided in the base 16
- reference numeral 23 denotes a hatch door
- reference numeral 24 denotes a top hall floor.
- the main rope 8 has one end thereof fixed at a point that is the position of the center of gravity of the car 3 in the plan view of the hoistway in the car frame 5, and the other end thereof fixed at a point that is substantially the position of the center of gravity of the counterweight 6 in the plan view of the hoistway in the top portion of the counterweight 6.
- the main rope 8 vertically ascends from the fixed point on the car frame 5, shifts into a horizontal direction via the first direction inverting pulley 13, shifts back via the sheave 10 of the hoisting machine 9, reverses vertically downward via the second direction inverting pulley 14, and reaches the fixed point on the counterweight 6.
- the hoisting machine 9 is installed such that it lies astride the edge portion 17 of the hoisting machine assembly 15 and the hoisting machine auxiliary support base 18 and that the brake inspection access port 19 is positioned in the vertical projection surface of the hoisting machine 9 with respect to the base 16.
- the hoisting machine 9 is set such that the rotating surfaces of the sheave 10 are horizontal, the sheave 10 faces toward the ceiling side of the hoistway 1, and the motor 11 and the brake 12 face downward.
- the hoisting machine 9 is disposed at a corner near the hatch door 23 in the plan view of the hoistway 1.
- the hoisting machine 9 is a so-called thin type hoisting machine, which is thinner in the direction of the rotating axis.
- the thin type hoisting machine refers to a hoisting machine in which its thickness in the direction of the rotating axis is smaller than its thickness in the direction perpendicular to the direction of the rotating axis, or a hoisting machine that is sufficiently thin to be accommodated in the gap between the car 3 at the top floor level and the ceiling surface of the hoistway 1.
- the thin type hoisting machine is, for example, the one disclosed in Japanese Unexamined Patent Publication No. 12-289954 , and the detailed descriptions thereof will be omitted.
- the hoisting machine 9 is disposed such that the majority of the height of the hoisting machine 9 (height B in the drawing) is accommodated within the height of the first direction inverting pulley 13 and the second direction inverting pulley 14 (height A in the drawing).
- the motor of the hoisting machine 9 is disposed within the height A of the first direction inverting pulley 13 and the second direction inverting pulley 14 so as to minimize the total height of the height A of the first direction inverting pulley 13 and the second direction inverting pulley 14 and the height B of the hoisting machine 9.
- the height of the hoisting machine assembly 15 (height C in the drawing) is set such that it is accommodated within the height of the equipment directly mounted on the hoisting machine assembly 15, i.e., the height of the first direction inverting pulley 13 and the second direction inverting pulley 14 (height A in the drawing).
- the counterweight 6 is disposed to ascend and descend along the hoistway wall 2 opposing the hatch door 23.
- the elevator apparatus according to this example is a so-called "counterweight back drop system” in which the counterweight 6 is disposed at the side opposing the hatch door 23.
- the first direction inverting pulley 13 is rotatably supported by the two opposing sides of the first opening 21, a part of the first direction inverting pulley 13 projecting downward beyond the base 16.
- the second direction inverting pulley 14 is rotatably supported by the two opposing sides of the second opening 22, a part of the second direction inverting pulley 14 projecting downward beyond the base 16.
- the hoisting machine 9 is installed such that it lies astride the edged portion 17 of the hoisting machine assembly 15 and the hoisting machine auxiliary supporting base 18, and the brake inspection access port 19 is positioned in the vertical projection surface of the hoisting machine 9 on the surface of the base 16. Furthermore, the hoisting machine 9 is set so that the motor 11 and the brake 12 face downward. This allows the motor 11 and the brake 12 to be visually checked from the direction of an arrow D shown in Fig. 4 , and also permits maintenance work to be accomplished from the direction of the arrow D.
- a plurality of ropes are used for the main rope 8, and the ropes are installed between the first direction inverting pulley 13 and the sheave 10 of the hoisting machine 9 such that the ropes are wound at a fleet angle 20 with respect to each rope groove of the first direction inverting pulley 13 or the sheave 10, as shown in the drawing. If the fleet angle 20 is large, then the side surfaces of the rope grooves and the main rope 8 are brought into intense contact, leading to a shortened life of the main rope 8. For this reason, it is preferable to install the first direction inverting pulley 13 and the sheave 10 spaced away from each other as much as possible thereby to minimize the fleet angle 20.
- the hoisting machine 9 is disposed at the corner close to the hatch door 23 in the plan view of the hoistway 1. Furthermore, the counterweight 6 is disposed on the side opposing the hatch door 23 to maximize the distance between the hoisting machine 9 and the second direction inverting pulley 14.
- the relationship between the second direction inverting pulley 14 and the sheave 10 is the same as the relationship between the first direction inverting pulley 13 and the sheave 10, so the explanation thereof will be omitted.
- the elevator apparatus discussed above is constructed to have one to one roping, thus obviating the need for the two car bottom return sheaves 26 on the bottom surface of the car 3 and the counterweight suspension sheave 27 of the counterweight 6. This makes it possible to reduce the number of components and to simplify the construction accordingly. Hence, the flexibility of the layout in the hoistway can be improved.
- the one to one roping construction allows the length of the main rope 8 to be reduced with a resultant reduction in cost.
- the hoisting machine 9 is installed such that the sheave 10 is located above the motor 11 and the brake 12, allowing the majority of the height of the hoisting machine 9 to be accommodated within the height of the first direction inverting pulley 13 and the second direction inverting pulley 14 in the direction of the height of the hoistway 1.
- the overhead dimension dimension OH in Fig. 1
- the hoistway 1 permits space saving in the hoistway 1 to be achieved.
- the hoisting machine 9 is of the thin type hoisting machine having a thin structure, the overhead dimension (dimension OH in Fig. 1 ) can be decreased, allowing space saving in the hoistway 1 to be achieved.
- the hoisting machine 9 is installed such that the motor 11 and the brake 12 face downward, and the brake inspection access portion 19 is provided in the vertical projection surface of the hoisting machine 9, permitting easy maintenance and inspection of the hoisting machine 9 to be performed.
- the base 16 is supported by the car rail 4 or the counterweight rail 7, obviating the need for providing a separate member for supporting the base 16. This permits a cost reduction to be achieved.
- the base 16 is supported by the wall of the hoistway 1, obviating the need for providing a separate member for supporting the base 16. This permits a cost reduction to be achieved.
- the hoisting machine 9 is disposed to extend beyond the vertical projection surface of the car 3 in the plan view of the hoistway 1, so that the gap between the first direction inverting pulley 13 and the second direction inverting pulley 14 and the sheave 10 can be maximized, and the fleet angle 20 can be increased. This arrangement enables the life of the main rope 8 to be prolonged.
- reference numeral 15 denotes a hoisting machine assembly that is formed of a planar base 16 providing its bottom surface, edge portions 17 with their sides at both ends shaped like U, and a hoisting machine auxiliary potion 25 provided such that it projects from one longer side.
- the hoisting machine assembly 15 is supported at its both short sides by a hoistway wall 2, and adapted to install a first direction inverting pulley 13 to the base 16.
- the two short sides of the hoisting machine assembly 15 are fixed on the hoistway wall 2 at the side where a hatch door 23 is installed and at a side opposing the side where the hatch door 23 is installed.
- Reference numeral 18 denotes a hoisting machine auxiliary supporting base secured to the hoistway wall 2 such that it is parallel to the edge portions 17 of the hoisting machine assembly 15 at the side of the hoistway wall 2 that opposes the hoisting machine auxiliary portion 25.
- a hoisting machine 9 is installed astride the edge portions 17 of the hoisting machine assembly 15 and the hoisting machine auxiliary support base 18, and is disposed at a corner close to the hatch door 23 in the plan view of the hoistway 1.
- the hoisting machine 9 is installed such that the rotating surfaces of a sheave 10 are horizontal and the sheave 10 faces the ceiling side of the hoistway 1, while a motor 11 and a brake 12 face downward.
- the hoisting machine 9 is disposed at a corner close to the hatch door 23 in the plan view of the hoistway 1.
- a pair of counterweight rails 7 is installed along the hoistway wall 2 at the side where the hoisting machine auxiliary support base 18 is installed in the plan view of the hoistway 1. More specifically, the counterweight 6 is adapted to ascend and descend along the hoistway wall 2 at the side where the hoisting machine auxiliary support base 18 is installed in the plan view of the hoistway 1, which represents a so-called "counterweight side drop system.”
- One of the counterweight rails 7 is disposed at the corner opposing the hatch door 23 in the plan view of the hoistway 1 so as to provide a maximum distance between the second direction inverting pulley 14 and the sheave 10 of the hoisting machine 9. The reason for this is as discussed in Example 1, i.e., to minimize the fleet angle 20.
- the second direction inverting pulley 14 lies astride the hoisting machine auxiliary portion 25 of the hoisting machine assembly 15 and the hoisting machine auxiliary supporting base 18, and is disposed at the top portion of the hoistway 1 in the ascending/descending direction of the counterweight 6.
- the first direction inverting pulley 13 is installed on the base 16 in the same manner as that in Example 1.
- Fig. 8 will be used for the explanation.
- the hoisting machine 9 is installed such that it lies astride the edged portions 17 of the hoisting machine assembly 15 and the hoisting machine auxiliary supporting base 18. Furthermore, the hoisting machine 9 is installed such that the motor 11 and the brake 12 face downward. This allows the motor 11 and the brake 12 to be visually checked from the direction of an arrow E shown in Fig. 8 , and also permits maintenance work to be accomplished from the direction of the arrow E.
- the elevator apparatus discussed above has the counterweight side drop system and also the one to one roping, so that it provides the advantage similar to that of Example 1 in the counterweight side drop system.
- the hoisting machine 9 is installed such that the motor 11 and the brake 12 face downward, and the hoisting machine 9 is installed such that it lies astride the edge portions 17 of the hoisting machine assembly 15 and the hoisting machine auxiliary supporting base 18; therefore, the maintenance and inspection of the hoisting machine 9 can be easily accomplished without providing the brake inspection access port 19 in the example.
- An elevator apparatus according to another example to which the present invention is applied, especially an elevator apparatus of the counterweight side drop system in which the angle of winding of a main rope onto a sheave is larger than that in the elevator apparatus in Example 2, will be explained in conjunction with Fig. 9 to Fig. 10 .
- the components assigned the like reference numerals as those in Example 1 will denote the like or equivalent components.
- Example 2 differs from Example 1 only in the disposition of a counterweight 6 and counterweight rails 7; hence, the descriptions will be given only of this different aspect.
- the two surfaces of a hoistway wall 2 that are in contact with the side where a hatch door 23 is installed in the plan view of the hoistway 1 will be referred to as side surfaces.
- a hoisting machine 9 is installed at one side surface of a hoistway wall 2.
- a counterweight 6 and counterweight rails 7 are disposed in contact with the other side surface of the hoistway wall 2, and between a car rail 4 and the side of the hoistway wall 2 at which the hatch door 23 is installed.
- a second direction inverting pulley 14 is installed at a different position from that in Example 1; it is installed above a counterweight 6 at the top portion of the hoistway 1.
- a hoisting machine assembly 15 is supported by the car rail 4 and the counterweight rails 7.
- the hoisting machine 9 installed on a hoisting machine assembly 15, the first direction inverting pulley 13 and a second direction inverting pulley 14 are concentrated substantially in the half surface adjacent to the hatch door 23 in the plan view of the hoistway 1. This arrangement has reduced the size of the hoisting machine assembly 15 substantially to the half of that of Example 1.
- the procedure for installing the hoisting machine 9, the first direction inverting pulley 13, and the second direction inverting pulley 14 on the hoisting machine assembly 15 is the same as that in Example 1.
- the angle of winding of the main rope 8 onto the sheave 10 is larger than that in Example 2, allowing the tractive capability of the sheave 10 to be enhanced.
- the angle of winding of the main rope 8 onto the sheave 10 depends upon the shapes of the plan views of the car 3 and the hoistway 1, so that the angle in Example 2 or in this example may be selected, whichever is better suited, depending on the condition under which the elevator apparatus is installed.
- the elevator apparatus discussed above permits the advantages similar to those of Example 1 to be obtained. Moreover, the angle of winding of the main rope 8 onto the sheave 10 can be increased, as necessary, so that the tractive capability of the sheave 10 can be improved.
- the area of the base 16 can be reduced, making it possible to cut down cost.
- the elevator apparatus is equipped with a car that ascends and descends along a car rail provided in a hoistway, a counterweight that ascends and descends along a counterweight rail provided in the hoistway, a hoisting machine that has a sheave, a motor for driving the sheave, and a brake for controlling the motor, and is disposed at the top portion of the hoistway such that a rotating surface of the sheave is horizontal, first and second direction inverting pulleys disposed at the top portion of the hoistway, and a main rope that has one end thereof connected to the car, while the other end thereof connected to the counterweight, and is wound onto the first and second direction inverting pulleys and the sheave to suspend the car and the counterweight.
- space saving in the hoistway can be achieved.
- the thickness of the hoisting machine in the direction of the rotating axis is smaller than the thickness in the direction perpendicular to the direction of the rotating axis, thus permitting space saving in the hoistway to be achieved.
- the elevator apparatus is further equipped with a hoisting machine assembly which is installed at the top portion of the hoistway and on which the hoisting machine and the first and second direction inverting pulleys are mounted. This arrangement makes it possible to save space in the hoistway.
- the hoisting machine assembly is supported by the car rail or the counterweight rail, obviating the need for providing a separate member for supporting the hoisting machine assembly.
- the hoisting machine assembly is supported by the wall of the hoistway, obviating the need for providing a separate member for supporting the hoisting machine assembly.
- the hoisting machine assembly is positioned such that its height is within the height of the first direction inverting pulley or the second direction inverting pulley in the direction of the height of the hoistway. Thus, space in the hoistway can be saved.
- the hoisting machine is disposed at a corner in the plan view of the hoistway, making it possible to maintain a large gap between the first direction inverting pulley or the second direction inverting pulley and the sheave.
- the hoisting machine is disposed at a corner in the plan view of the hoistway such that it extends beyond the vertical projection surface of the car in the plan view of the hoistway. This makes it possible to maintain a large gap between the first direction inverting pulley or the second direction inverting pulley and the sheave.
- the hoisting machine is disposed such that the brake is positioned at the lower side in the hoistway, permitting maintenance and inspection to be easily carried out.
- the hoisting machine is disposed on the top surface of the hoisting machine assembly such that the brake faces the lower end of the hoistway, and the hoisting machine assembly is equipped with an inspection access port provided to penetrate the vertical projection surface of the hosting machine. This permits easy maintenance and inspection.
