An elevator apparatus is provided with an elevator path having a restricted height. Under a roping ratio of 1:1, a thin driving unit having a traction sheave 1 and a driving mechanism 2 is positioned between an inner wall 3 a of the elevator path 3 and a space occupied by an elevator car 4 rising and falling in the elevator path 3. One end of a suspension rope 7 is fixed to the elevator car 4 in a position below a ceiling 4 c of the elevator car 4. With the arrangement, the car 4 can move close to the ceiling 4 c of the elevator car 4 effectively. Further, it is possible to reduce respective heights of the elevator path 3 and a building equipped with the elevator apparatus.
This application is a Division of application Ser. No. 09/300,072 filed on Apr. 27, 1999 now U.S. Pat. No. 6,247,557.
Japanese Unexamined Patent Publication (kokai) No. 9-156855 discloses another elevator apparatus shown in FIG. 2. In the apparatus, the flattened driving mechanism 2 is arranged in the upper space of the balance weight 6 and adapted so as to suspend the car 4 through turning sheaves 8 a, 8 b and 8 c.
In this way, since the driving mechanism 2 having the traction sheave 1 is disposed between a side wall 3 a in an elevator path 3 and a space defined by projected planes of an elevator car 4 in the upward and downward directions, the arrangement allows to minimize a space that the whole apparatus does occupy without providing the machine room on the roof, so that the elevator apparatus can be provided while exhibiting high efficiency in utilizing the space.
While, in the latter elevator apparatus, the velocity of the suspending rope is equal to that of the elevator car owing to the provision of the turning sheaves. Nevertheless, there is remained a problem in terms of effective use of space in the elevator path because the apparatus requires a space for accomodating the turning sheaves on the upper side of the elevator path.
According to the elevator apparatus constructed above, the drive of the elevator car at the same speed as the suspension rope can be realized owing to the achievement of roping ratio of 1:1. In addition, with the arrangement where the elevator car is connected with the suspension rope in a position below the ceiling of the elevator car and there is provided no turning sheave etc. in a space above the elevator car, the upper area of the elevator path can be effectively utilized thereby to provide a high-speed and compact elevator apparatuses
With the attachment of the driving unit on the side of the elevator path, the burden applied on the elevator guide rails is lightened thereby to reduce the weigh of the driving unit.
a pair of elevator guide rails disposed in an elevator path; an elevator car for rising and falling along the elevator guide rails in the elevator path;
wherein the suspension rope is wound round the turning sheaves on the elevator car and the balance weight, while both ends of the suspension rope are connected to supporting members mounted on an upper end of the elevator path;
an elevator car for rising and falling along the elevator guide rails in the elevator path,
Similarily the object of the present invention described above can be also accomplished by an elevator apparatus comprising:
FIG. 3 is a perspective view of the elevator apparatus in accordance with the first embodiment of the invention, showing an essential part thereof;
FIG. 9 is a perspective view of an essential part of the elevator apparatus in accordance with the fourth embodiments of the invention;
FIG. 17 a plan view of the elevator apparatus of FIG. 16;
FIG. 18A is a perspective view of an essential part of the elevator apparatus in accordance with the ninth embodiment of the invention;
FIG. 18B is a perspective view of an essential part of the elevator apparatus in accordance with an alternative arrangement of the ninth embodiment of the invention;
FIG. 19 is a plan view of the elevator apparatus of FIG. 18A;
First of all, the embodiments described therein are divided broadly into two groups. In common with the first group of the first to seventh embodiments, an suspension (or hoisting) rope has one end coupled to an elevator car in a position below the roof of the elevator car. While, in common with the second group of the subsequent embodiments, the elevator car is provided, on one or both sides thereof, with a turning sheave around which the suspension rope is wound.
According to the embodiment, a pair of elevator guide rails 9 a, 9 b each having a T-shaped cross section are attached to the side walls 3 a defining the elevator path 3 through not-shown brackets. On the left side of the floor 4 a of the elevator car 4, a hitch part 4 b is formed so as to laterally project at a position below the roof 4 c of the car 4. The hitch part 4 b is connected to one end of the suspension rope 7 through a not-shown hitch spring.
As to this movement, when the elevator car 4 is elevated, then the car roof 4 c is capable of rising in excess of the height of the driving mechanism 2 owing to the arrangement where the elevator car 4 is connected to the suspension rope 7 at the hitch part 4 b below the car roof 4 c.
Thus, as mentioned above, since the elevator apparatus of the first embodiment is constructed with the roping ratio of 1:1, both elevator car 4 and suspension rope 7 are driven at the same velocity thereby to realize the high-speed operation. Additionally, since the driving unit consisting of the traction sheave 1 and the driving mechanism 2 are accommodated in the clearance defined between the side wall 3 a of the elevator path 3 and the space being occupied by the car 4 in the process of moving upward and downward, the car 4 can rise to the vicinity of the ceiling of the elevator path 3, so that it is possible to-hold the height of the elevator path 3 to a minimum, thereby accomplishing the space-saving of the apparatus.
From this point of view, we now describe the second embodiment where the driving unit is constituted by a plurality of driving mechanisms thereby realizing both high-speed and large-capacity elevator apparatus,with reference to FIGS. 5 and 6.
According to the embodiment shown in FIG. 7, one of the guide rails 9 aand 9 c, i.e. the guide rail 9 c is formed to have a H-shaped cross section, so which is largely shown in FIG. 8, too. The guide rail 9 c is fixed on the side wall 3 a of the elevator path 3 by a not-shown bracket in a manner that parallel sides of the rail 9 c oppose the elevator car 4.
In the above-constructed arrangement of the third embodiment, the is elevator car 4 is guided by the upper and lower roller assemblies 12 a, 12 b while being supported by the vertical beam 11 a. Then, the elevator's rolling about the longitudinal axis of the guide rail 9 c can be restricted by the rollers 12 aa, 12 ab urging the side portion 9 ca from the inside and outside.
On the lower side of the car 4, pitch parts. 4 ba, 4 bb for connection with the suspension rope 7 are arranged symmetrically with each other about the gravity center of the elevator car 4. Further, the sheaves 8 d, 8 g corresponding to the hitch parts 4 ba, 4 bb are attached on the side walls 3 a defining the elevator path 3 so as not to interfere with the occupied space by the car 4 in the process of moving upward and downward.
Either of the so-divided suspension ropes 7 has one end connected with the elevator car 4 at the hitch part 4 ba through the intermediary of the sheave 8 d attached on the wall 3 a. While, another suspension rope 7 has one end connected with the elevator car 4 at the hitch part 4 bb through the intermediary of the sheave 8f attached on the side wall 3 a at an angle of approx. 45 degrees and the sequent sheave 8 g also attached on the right side wall 3 a at an angle of approx. 45 degrees.
Although the balance weights 6A, 6B are disposed on the left and right sides of the car 4 in the above-mentioned fifth embodiment, they may be replaced with the common balance weight in order to realize the apparatus, of simple structure.
According to the embodiment, there are provided the driving mechanisms 2A, 2B which have the traction sheaves 1A, 1B arranged in the vicinity of the guide rails 9 a, 9 b, respectively. In the rear part of the elevator path 3 between the guide rails 9 a and 9 b, the common balance weight 6 is adapted so as to rise and fall under the guidance of the rails 10 a, 10 b.
On the left and right sides of the car 4, the suspension ropes 7A, 7B respectively connected to the hitch parts 4 ba, 4 bb below the car roof 4 c are wound round the traction sheaves 1A, 1B, respectively and the ropes 7A, 7B are coupled to the common balance weight 6 finally.
Also in this embodiment, the left and right driving mechanisms 2A, 2B are controlled by the single control unit, so that the elevator car 4 can rise and fall owing to the mechanisms synchronous operation at the same speed. Again, the elevator car 4 does rise and fall at speed equal to those of the suspension ropes 7A, 7B owing to the thrust force by the driving mechanisms 2A, 2B. As similar to the first to fifth embodiments, since the driving unit and the sheaves 8 ha, 6 hb, 8 ia, 8 ib are arranged so as not to interfere with the occupied space by the car 4 in the process of moving upward and downward, it is possible to reduce the height of the elevator path 3 to a minimum.
A pair of guide rails 27 a, 27 b for balance weight are arranged in a position adjacent to the guide rail 20 a, for allowing a balance weight 28 to rise and fall under their guidance. Attached on the top of the balance weight 28 is a turning sheave 29 about which the suspension rope 23 is also wound to hang the weight 28. Both ends of the suspension rope 23 are connected to supporting members (not shown) and carried by the members, which are built in the ceiling of the elevator path 24 over the elevator car 21, through the it intermediary of hitch springs also not shown in the figure.
Thus, according to the embodiment, since the elevator car 21 hung by the suspension rope 23 performs an action like a moving pulley due to the turning sheave 22, it is possible to reduce the power capacity required for the driving unit 26 in comparison with that required for the driving unit 26 in direct hanging the car 21 by the traction sheave 25. Repeatedly since the driving unit 26 is arranged in a space in the elevator path 24, between the side wall 24 a of the elevator path 24 and the space being occupied by the rising and falling elevator car 21 and additionally, the elevator car 21 can rise and fall close to the ceiling and floor of the elevator path 24 without requiring any more space above or beneath the path 24, it is possible to establish a height of the path 24 to a minimum.
The ninth embodiment will be described below, with reference to FIGS. 18A, 18B and 19. The ninth embodiment is differentiated from the eighth embodiment in that a balance weight 28 is guided by the guide rails 27 a, 27 b provided on a back wall 24 of the elevator path 24, for the weight's free elevation and that the elevator car 21 is provided, on a back face 21 d thereof, with the turning sheave 22. Further, the elevator apparatus in accordance with the ninth embodiments shown in FIGS. 18A and 19 is characterized in that the flat and thin driving unit 26 is mounted on the guide rail 27 a for the balance weight and the traction sheave 25 is positioned in the clearance between the back wall 24 b of the elevator path 24 and the space being occupied by the moving elevator car 21. The other structure of the ninth embodiment is similar to that of the eighth embodiment of FIGS. 16 and 17 and therefore, the elements similar to those of the eighth embodiment are indicated with the same references, respectively.
FIG. 18B illustrates an alternative arrangement of the ninth embodiment including a plurality of driving units 26 a, 26 b respectively including traction sheaves 25 a, 25 b for rewinding the sheaves 25 a, 25 b synchronously, which are used in place of the driving unit 26 of FIG. 18A. This is similar to the driving units 26 a, 26 b and traction sheaves 25 a, 25 b shown in FIG. 27, for example. Likewise, the driving units 26 a, 26 b shown in FIG. 18B may be arranged horizontally such as shown in FIG. 28.
According to the embodiment, a pair of bilaterally symmetrical turning sheaves 22 a,22 b are respectively attached on the side faces 21 a, 21 e of the elevator car 21, which is guided by the guide rails 20 a, 20 b secured on the side walls of the elevator path 24 through not-shown brackets, and furthermore, the elevator car 21 is provided, on the underside of a floor face 21 f, with turning sheaves 22 c, 22 d having respective rotating planes parallel with the floor face 21 f. The suspension rope 23 is wound round these turning sheaves 22 a to 22 d. Adjacent to the guide rail 20 b, a pair of guide rails 27 a, 27 b are fixed on the side wall of the elevator path 24, for guiding the rise and fall of the balance weight 28. Note, the balance weight 28 is provided, at a top thereof, with a turning sheave 29.
Also in this embodiment, since the elevator car 21 hung by the suspension rope 23 also performs an action like a moving pulley, it is possible to reduce the power capacity required for the driving unit 26. Repeatedly since the driving unit 26 having the traction sheave 25 is arranged in a space in the elevator path 24, between the side wall 24 a of the elevator path 24 and the space being occupied by the rising and falling elevator car 21 and additionally, the elevator car 21 can rise and fall close to the ceiling and floor of the elevator path 24 without requiring any more space above or beneath the path 24, it is possible to establish the height of the path 24 to a minimum. Furthermore, the elevator apparatus of the embodiment has the advantage of freely establishing the positions of the turning sheaves 22 e, 22 f, 22 g, 22 h, attached on the side faces 21 a, 21 e of the elevator 21 respectively, together with the positions of the accompanying turning sheaves 22 i, 22 j on the ceiling face 21 c.
Referring to FIGS. 22 and 23, we now describe the elevator apparatus in accordance with the twelfth embodiment. The twelfth embodiment is characterized by the arrangement where turning sheaves 22 k and 221 in place of the above turning sheaves 22 i, 22 j in the eleventh embodiment of FIG. 21 are disposed on the back face 21 d. Further, positioned in the clearance between the back wall of the elevator path 24 and the space being occupied by the rising and falling elevator car 21 are not only the driving unit 26 and the traction sheave 25 but the elevating balance weight 28.
Also in this embodiment, it is possible to reduce the power capacity required for the driving unit 26, as similar to the eleventh embodiment. Repeatedly, the driving unit 26 having the traction sheave 25 is arranged in the clearance defined between the back wall of the elevator path 24 and the space being occupied by the rising and falling elevator car 21. Additionally, the elevator car 21 can rise and fall close to the ceiling and floor of the elevator path 24 without requiring any more space above or beneath the path 24. Therefore, it is possible to establish the height of the path 24 to a minimum. Furthermore, the elevator apparatus of the embodiment has the advantage of freely establishing the positions of the turning sheaves 22 e, 22 f, 22 g, 22 h attached on the side faces 21 a, 21 e of the elevator car 21 respectively, together with the positions of the accompanying turning sheaves 22 k, 22 l on the back face 21 d.
The suspension rope 23 is wound round the turning sheave 29 on the balance weight 28, while one end 23 a of the rope 23 is connected to the ceiling of the elevator path 24. By way of an upper half periphery of the upper traction sheave 25 a, a lower half periphery of the lower traction sheave 25 b, the upper half periphery of the upper traction sheave 25 a again and the turning sheave 22 on the side face 21 e of the car 21 in order, the other end 23 b of the rope 23 is finally connected to the ceiling of the elevator path 24. With the above-mentioned wiring, it is possible to equally wind the suspension rope 23 about two traction sheaves 25 a, 25 b by three quarters of the whole periphery of each sheave. Note, the upper traction sheave 25 a is provided, for receiving the suspension rope 23, with a groove whose width is twice as large as that of the lower traction sheave 25 b.
According to the fifteenth embodiment of the invention, since the driving units 26 a, 26 b operate to wind the suspension rope 23, it is possible to double the thrust for driving the elevator car 21 thereby to cope with the driving of a large capacity of elevator car 21.
In connection, the driving units 26 a, 26 b may be arranged horizontally, as shown in the modification of FIG. 28. In this case, the suspension rope 23 is successively brought to the upper part (one fourth of the whole periphery) of the front:.traction sheave 25 a from the underside, the sequential rear half round of the rear traction sheave 25 b, the half round of the front traction sheave 25 a from the underside again and the upper part (one fourth of the whole periphery) of the rear traction sheave 25 b again and thereafter, to the downside. Finally, the rope 23 is wound round the turning sheave 22 on the side face 21 e of the car 21. In this way, it is possible to equally wind the suspension rope 23 about two traction sheaves 25 a, 25 b by three quarters of the whole periphery of each sheave.
Referring to FIGS. 29 and 30, we now describe the elevator apparatus in accordance with the sixteenth embodiment. In case of the tenth to fourteenth embodiments where the turning sheaves are mounted on both side faces 21 a, 21 e of the elevator car 21 or the side faces 21 a, 21 e and the back face 21d or the roof face 21 c, the turning sheaves 22 a to 22 d may be arranged in symmetry about the gravity center G of the car 21, as shown with the symmetrical arrangement (of 180 degrees) of FIG. 29, representatively.
