Description

Technical Field

[0001] This specification relates to an elevator car and an elevator.

Background Art

[0002] Conventionally, for example, an elevator car includes a car frame, a car sheave around which a car rope is wound, the car sheave being rotatably connected to the car frame about a first lateral direction as an axis, a stop movable part movable between a standby position and a stop position where it stops on a car rail, and an operating part connecting a governor rope and the stop movable part to operate the stop movable part (for example, Patent Document 1).

[0003] And in the elevator car according to Patent Document 1, the car sheave is disposed between the governor rope and the stop movable part in the first lateral direction. Accordingly, the operating part needs to transmit the force by the governor rope to the stop movable part disposed farther than the car sheave.

[0004] By the way, in the elevator car according to Patent Document 1, the operating part includes a rope connection part connected to the governor rope, and the rope connection part rotates about a second lateral direction orthogonal to the first lateral direction with respect to the car frame. As a result, when the rope connection part swings about the second lateral direction, the governor rope vibrates in the first lateral direction, so that the governor rope vibrates so as to approach or move away from the car rope. And when the governor rope approaches the car rope too much, for example, there is a risk that the governor rope contacts the car rope.

Mode for Carrying Out the Invention

[0010] In each drawing, the dimensions of the components may be enlarged or reduced with respect to the actual dimensions for ease of understanding, for example, and the dimensional ratios between the drawings may not match. Note that in each drawing, a part of the components may be omitted for ease of understanding, for example.

[0011] Terms including ordinal numbers such as first, second, etc. are used to describe various components, but this term is used only for the purpose of distinguishing one component from another, and the components are not particularly limited by this term. Note that the number of components including ordinal numbers is not particularly limited, and may be, for example, one. Also, the ordinal numbers used in the following specification and drawings may be different from the ordinal numbers described in the claims.

[0012] As shown in FIG. 1, the elevator 1 may include, for example, an elevator car (hereinafter also simply referred to as a "car") 10 for a person (passenger) to ride in, a car rope 2 connected to the car 10, a counterweight 3 connected to the car rope 2, a hoist 4 that drives the car rope 2 to move the car 10 and the counterweight 3 in the vertical direction D3, a car rail 5 that guides the car 10, a weight rail 6 that guides the counterweight 3, and a speed governor 7 that detects the traveling speed of the car 10.

[0013] In each figure, the first direction D1 is the first horizontal direction D1, the second direction D2 is the second horizontal direction D2 which is a horizontal direction orthogonal to the first horizontal direction D1, the third direction D3 is the vertical direction D3 which is orthogonal to each of the horizontal directions D1 and D2, and is the elevating direction in which the cage 10 and the counterweight 3 move up and down.

[0014] The hoisting machine 4 may include, for example, as in the present embodiment, a sheave 4a around which the cage rope 2 is wound, a drive source 4b (for example, a motor) for rotating the sheave 4a, and a braking unit 4c for braking the sheave 4a. Note that the elevator 1 according to the present embodiment has a configuration in which the hoisting machine 4 is disposed inside the hoistway X1, but is not limited to such a configuration. For example, the elevator 1 may have a configuration in which the hoisting machine 4 is disposed inside a machine room provided above the hoistway X1.

[0015] The speed governor 7 includes an endless annular governor rope 7a connected to the cage 10 so as to run as the cage 10 moves. Further, the speed governor 7 may include, for example, as in the present embodiment, a governor sheave 7b around which the governor rope 7a is wound, a tension pulley 7c suspended from the governor rope 7a to apply tension to the governor rope 7a, and a governor stop portion 7d for stopping the running of the governor rope 7a when the cage 10 moves downward at a set speed.

[0016] The configuration of the governor stop portion 7d is not particularly limited. For example, when the cage 10 moves downward at a set speed and the governor sheave 7b rotates at a set rotational speed, the governor stop portion 7d may be configured to stop the running of the governor rope 7a by gripping the governor rope 7a. Note that the set speed may be, for example, greater than the rated speed (maximum speed during normal operation) of the cage 10, and may be, for example, 110% to 120% of the rated speed of the cage 10.

[0017] As shown in FIGS. 1 to 4, the car 10 includes a car frame 11, car sheaves 12 and 13 around which a car rope 2 is wound and which are rotatably connected to the car frame 11 about a first lateral direction D1, and a stopping device 20 for stopping the car 10 on a car rail 5. Note that the number of the car sheaves 12 and 13 is not particularly limited. The car sheaves 12 and 13 may be, for example, two, or may be, for example, one or three or more.

[0018] Further, the car 10 may include, for example, a car cabin 14 for a person to ride in and a guide roller 15 guided by the car rail 5 as in the present embodiment. The car frame 11 may be fixed to the car cabin 14 as in the present embodiment.

[0019] In FIGS. 1 to 4, the car frame 11 is shown only below the car cabin 14, but the car frame 11 may be arranged, for example, around the car cabin 14. Specifically, the car frame 11 may be arranged, for example, below, above, and on the sides of the car cabin 14, respectively. Further, the car frame 11 may include a plurality of frame members as in the present embodiment.

[0020] As shown in FIGS. 2 to 7, the stopping device 20 includes a first stoppable movable part 21 movable between a standby position and a stopping position for stopping the car 10 on the car rail 5, and a first operating part 30 connecting a governor rope 7a and the first stoppable movable part 21 to operate the first stoppable movable part 21. The first car sheave 12 is arranged between the governor rope 7a and the first stoppable movable part 21 in the first lateral direction D1.

[0021] Further, the stopping device 20 may include, for example, a second stoppable movable part 22 movable between a standby position and a stopping position for stopping the car 10 on the car rail 5 as in the present embodiment, first and second stopping fixed parts 23 and 24 fixed to the car frame 11, and a second operating part 50 connecting the first operating part 30 and the second stoppable movable part 22 to operate the second stoppable movable part 22.

[0022] The stop movable parts 21 and 22 may be movable relative to the stop fixing parts 23 and 24, for example, between a stop position and a standby position below the stop position. Note that the stop position is the position indicated by the two-dot chain line in Fig. 7, and the standby position is the position shown in Figs. 2 to 6 and the position indicated by the solid line in Fig. 7.

[0023] And, for example, when the car 10 moves downward at a set speed, the governor stop part 7d (see Fig. 1) stops the running of the governor rope 7a and the car 10 moves downward, so that the stop movable parts 21 and 22 move from the standby position to the stop position. Then, for example, when the stop movable parts 21 and 22 are located at the stop position, the stop movable parts 21 and 22 cooperate with the stop fixing parts 23 and 24 to press and contact the car rail 5, so that the car 10 stops on the car rail 5.

[0024] As shown in Figs. 5 to 8, the first operation part 30 includes a first rotating part 31 rotatably connected to the car frame 11, a second rotating part 32 rotatably connected to the car frame 11 and separate from the first rotating part 31, and a first operation connection part 33 connecting the first rotating part 31 and the second rotating part 32. Further, the first operation part 30 may include a biasing part 34 that applies a force toward the standby position to the stop movable parts 21 and 22, for example, as in this embodiment.

[0025] The first rotating part 31 includes a rope connection part 35 connected to the governor rope 7a, and a first rotating shaft part 36 to which the rope connection part 35 is fixed and which is rotatably connected to the car frame 11 about the first lateral direction D1. The governor rope 7a may be rotatably connected to the rope connection part 35 about the first lateral direction D1, for example, as in this embodiment.

[0026] The second rotating part 32 includes a first stop connection part 37 connected to the first stop movable part 21, and a second rotating shaft part 38 to which the first stop connection part 37 is fixed and which is rotatably connected to the car frame 11 about the first lateral direction D1. The first stop movable part 21 may be rotatably connected to the first stop connection part 37 about the first lateral direction D1, for example, as in the present embodiment.

[0027] In this way, the first rotating shaft part 36 to which the force is transmitted from the governor rope 7a and the second rotating shaft part 38 that transmits the force to the first stop movable part 21 are separate bodies. As a result, although the rope connection part 35 and the first stop connection part 37 are far apart in the first lateral direction D1, for example, the lengths of the rotating shaft parts 36 and 38 can be shortened. Therefore, the mechanical strength required for the rotating shaft parts 36 and 38 can be reduced.

[0028] Moreover, for example, since the arrangement of the first rotating shaft part 36 and the second rotating shaft part 38 can be flexibly corresponded, the degree of freedom in the design of the car 10 can be improved. For example, as in the present embodiment, the first rotating shaft part 36 and the second rotating shaft part 38 may be configured to be separated in the view of the first lateral direction D1. Also, for example, as in the present embodiment, the first rotating shaft part 36 and the second rotating shaft part 38 may be configured to be separated from each other in the view of the second lateral direction D2 and the vertical direction D3.

[0029] Also, for example, considering the position of the first car sheave 12, the positions of the first rotating shaft part 36 and the second rotating shaft part 38 can be designed. For example, the lower end of the first car sheave 12 is the lower end of the car 10. On the other hand, the upper end of the car sheave 12 is arranged above the second rotating shaft part 38. Thereby, it is possible to suppress the lower end of the car sheave 12 from being excessively separated downward from the car frame 11, and thus it is possible to suppress the vertical dimension D3 of the elevator car 10 from becoming too large.

[0030] Also, a part of the first car sheave 12 is disposed outside the end position 11b in the second lateral direction D2 of the car frame 11. In contrast, the second rotating shaft portion 38 is away from the first car sheave 12 when viewed in the second lateral direction D2, and overlaps the first car sheave 12 when viewed in the first lateral direction D1. Thereby, since the second rotating shaft portion 38 is disposed in the region of the end portion in the second lateral direction D2 of the car frame 11, it is possible to suppress the length of the first stop connection portion 37 from becoming too long.

[0031] In addition, for example, like this embodiment, the first rotating shaft portion 36 may be configured to overlap the first car sheave 12 when viewed in the vertical direction D3 and be away from the first car sheave 12 when viewed in the first lateral direction D1 and the second lateral direction D2. Also, for example, like this embodiment, the second rotating shaft portion 38 may be configured to overlap the first car sheave 12 when viewed in the first lateral direction D1 and be away from the first car sheave 12 when viewed in the second lateral direction D2 and the vertical direction D3.

[0032] The number of the first stop movable portions 21 is not particularly limited. For example, like this embodiment, two may be used, or one or three or more may be used. Also, the number of the first stop connection portions 37 is not particularly limited. For example, like this embodiment, two may be used, or one or three or more may be used.

[0033] The first operation connection portion 33 includes a first shaft fixing portion 39 fixed to the first rotating shaft portion 36, a second shaft fixing portion 40 fixed to the second rotating shaft portion 38, and a first fixing connection portion 41 that is rotatably connected to the first shaft fixing portion 39 about the first lateral direction D1 and is rotatably connected to the second shaft fixing portion 40 about the first lateral direction D1. Thereby, the first shaft fixing portion 39 and the second shaft fixing portion 40 are connected by the first fixing connection portion 41.

[0034] The second operation unit 50 may include, for example, as in the present embodiment, a third rotation unit 51 rotatably connected to the car frame 11, and a second operation connection unit 52 connecting the third rotation unit 51 and the second rotation unit 32 of the first operation unit 30. The third rotation unit 51 may include, for example, as in the present embodiment, a second stop connection unit 53 connected to the second stop movable unit 22, and a third rotation shaft unit 54 to which the second stop connection unit 53 is fixed and which is rotatably connected to the car frame 11 about the first lateral direction D1.

[0035] The second stop movable unit 22 may be rotatably connected to the second stop connection unit 53 about the first lateral direction D1, for example, as in the present embodiment. The number of the second stop movable units 22 is not particularly limited, and may be two, for example, as in the present embodiment, or may be one or three or more, for example. Also, the number of the second stop connection units 53 is not particularly limited, and may be two, for example, as in the present embodiment, or may be one or three or more, for example.

[0036] The second operation connection unit 52 may include, for example, as in the present embodiment, a third shaft fixing unit 55 fixed to the second rotation shaft unit 38 of the first operation unit 30, a fourth shaft fixing unit 56 fixed to the third rotation shaft unit 54, and a second fixing connection unit 57 rotatably connected to the third shaft fixing unit 55 about the first lateral direction D1 and rotatably connected to the fourth shaft fixing unit 56 about the first lateral direction D1. Thereby, the third shaft fixing unit 55 and the fourth shaft fixing unit 56 are connected by the second fixing connection unit 57.

[0037] The operation units 30 and 50 may include, for example, as in the present embodiment, bearing units 42 and 58 that rotatably connect the rotation shaft units 36, 38, and 54 to the car frame 11. Although not particularly limited, the bearing units 42 and 58 may be, for example, bushings (plain bearings) or bearings. Also, the rotation shaft units 36, 38, and 54 may be inserted into the through holes 11a of the car frame 11, for example, as in the present embodiment.

[0038] Here, the operation of the stop device 20 will be described.

[0039] For example, when the governor stop portion 7d (see FIG. 1) stops the running of the governor rope 7a and the cage 10 moves downward, the rope connection portion 35 and the first rotating shaft portion 36 rotate about the first lateral direction D1. As a result, the second rotating shaft portion 38 and the first stop connection portion 37 rotate about the first lateral direction D1, and the third rotating shaft portion 54 and the second stop connection portion 53 rotate about the first lateral direction D1. Therefore, the first stop movable portion 21 and the second stop movable portion 22 move from the standby position to the stop position.

[0040] By the way, since the rope connection portion 35 rotates integrally with the first rotating shaft portion 36, the rope connection portion 35 rotates about the first lateral direction D1 with respect to the cage frame 11. Therefore, for example, when the cage 10 accelerates or vibrates and the rope connection portion 35 swings, the governor rope 7a will vibrate in the second lateral direction D2.

[0041] Thereby, it is possible to suppress a change in the distance between the governor rope 7a and the cage rope 2 (see FIG. 4). As a result, even when the rope connection portion 35 swings with respect to the configuration in which the first cage sheave 12 is disposed between the governor rope 7a and the first stop movable portion 21, it is possible to suppress the governor rope 7a from vibrating so as to approach the cage rope 2.

[0042] In addition, the first and second rotating portions 31 and 32 rotatably connected to the cage frame 11 are rotatably connected to the cage frame 11 about the first lateral direction D1. Specifically, all of the rotating portions 31 and 32 of the first operating portion 30 are rotatably connected to the cage frame 11 about the first lateral direction D1.

[0043] Thereby, when the rope connection portion 35 swings, since the first and second rotating portions 31 and 32 swing about the first lateral direction D1, it is possible to suppress a change in the distance between the first and second rotating portions 31 and 32 and the first cage sheave 12. Therefore, even when the rope connection portion 35 swings, it is possible to suppress the first and second rotating portions 31 and 32 from swinging so as to approach the first cage sheave 12.

[0044] Note that the third rotating part 51 rotatably connected to the cage frame 11 is also rotatably connected to the cage frame 11 about the first lateral direction D1. Thereby, when the rope connection part 35 swings, since the third rotating part 51 swings about the first lateral direction D1, it is possible to suppress a change in the distance between the third rotating part 51 and the second cage sheave 13. Therefore, even when the rope connection part 35 swings, it is possible to suppress the third rotating part 51 from swinging so as to approach the second cage sheave 13.

[0045] Next, the specific configuration of the first operating part 30 will be described with reference to FIGS. 8 and 9.

[0046] As shown in FIG. 8, the first fixed connection part 41 is rotatably connected to the first shaft fixing part 39 about the first lateral direction D1 at the first rotation center position 41a. Further, the first fixed connection part 41 is rotatably connected to the second shaft fixing part 40 about the first lateral direction D1 at the second rotation center position 41b.

[0047] And, in the view of the first lateral direction D1, a first straight line L1 connecting the first rotation center position 41a and the first shaft center position 36a of the first rotation shaft part 36 is parallel to a second straight line L2 connecting the second rotation center position 41b and the second shaft center position 38a of the second rotation shaft part 38. Moreover, in the view of the first lateral direction D1, a third straight line L3 connecting the first rotation center position 41a and the second rotation center position 41b is parallel to a fourth straight line L4 connecting the first shaft center position 36a and the second shaft center position 38a.

[0048] Therefore, in the view in the first horizontal direction D1, the first to fourth straight lines L1 to L4 form a parallelogram. And in the view in the first horizontal direction D1, the length of the first straight line L1 (the distance between the first rotation center position 41a and the first axis center position 36a) is the same as the length of the second straight line L2 (the distance between the second rotation center position 41b and the second axis center position 38a), and the length of the third straight line L3 (the distance between the first rotation center position 41a and the second rotation center position 41b) is the same as the length of the fourth straight line L4 (the distance between the first axis center position 36a and the second axis center position 38a).

[0049] As a result, as shown in FIG. 9, the rotation angle θ1 of the first rotating shaft portion 36 and the rotation angle θ2 of the second rotating shaft portion 38 are the same. Therefore, for example, the design of the first operating portion 30 can be facilitated. In this specification, the term "parallel" includes not only the case of being completely parallel but also the case of being substantially parallel with an intersection angle of 5° or less.

[0050] Further, the first operation connection portion 33 is disposed inside the end position 11b in the second horizontal direction D2 of the cage frame 11. Thereby, it is possible to suppress the first operation connection portion 33 from protruding from the end position 11b in the second horizontal direction D2 of the cage frame 11. Therefore, for example, it is possible to suppress the first operation connection portion 33 from colliding with components in the hoistway X1. Although not particularly limited, for example, as in the present embodiment, the lengths of the first straight line L1 and the second straight line L2 may be shorter than the lengths of the third straight line L3 and the fourth straight line L4, respectively.

[0051] Although not particularly limited, for example, in the present embodiment, each of the first rotating shaft portion 36, the second rotating shaft portion 38, the first shaft fixing portion 39, the second shaft fixing portion 40, and the first fixing connection portion 41 is disposed inside the end position 11b in the second horizontal direction D2 of the cage frame 11. Thereby, for example, in the first operating portion 30, the portion protruding from the end position 11b in the second horizontal direction D2 of the cage frame 11 can be reduced.

[0052] [1] From the above, the elevator car 10 is, as in the present embodiment, An elevator car 10 that travels in the vertical direction D3 by being guided by a car rail 5, a car frame 11, a car rope 2 is wound around, and a car sheave (in this embodiment, a first car sheave) 12 that is rotatably connected to the car frame 11 about a first lateral direction D1, and a stopping device 20 that stops the elevator car 10 on the car rail 5, wherein the stopping device 20 includes a stoppable movable part (in this embodiment, a first stoppable movable part) 21 that is movable from a standby position to a stopping position where the elevator car 10 is stopped on the car rail 5, and an operating part (in this embodiment, a first operating part) 30 that connects a governor rope 7a and the stoppable movable part 21 in order to operate the stoppable movable part 21, the car sheave 12 is disposed between the governor rope 7a and the stoppable movable part 21 in the first lateral direction D1, the operating part 30 includes a rope connection part 35 connected to the governor rope 7a, the rope connection part 35 rotates about the first lateral direction D1 with respect to the car frame 11, is preferably configured as such.

[0053] According to such a configuration, the rope connection part 35 rotates about the first lateral direction D1 with respect to the car frame 11. Thereby, when the rope connection part 35 swings, the governor rope 7a vibrates in the second lateral direction D2.

[0054] Therefore, it is possible to suppress a change in the distance between the governor rope 7a and the car rope 2. As a result, even when the rope connection part 35 swings with respect to a configuration in which the car sheave (in this embodiment, the first car sheave) 12 is disposed between the governor rope 7a and the stoppable movable part (in this embodiment, the first stoppable movable part) 21, it is possible to suppress the governor rope 7a from vibrating so as to approach the car rope 2.

[0055] [2] Also, in the elevator car 10 of [1] above, as in this embodiment, the operation part (in this embodiment, the first operation part) 30 includes a first rotating part 31 including the rope connection part 35, a second rotating part 32 that is separate from the first rotating part 31, and an operation connection part (in this embodiment, the first operation connection part) 33 that connects the first rotating part 31 and the second rotating part 32. The first rotating part 31 includes a first rotating shaft part 36 to which the rope connection part 35 is fixed and which is rotatably connected to the car frame 11 about the first lateral direction D1. The second rotating part 32 includes a stop connection part (in this embodiment, the first stop connection part) 37 connected to the stop movable part (in this embodiment, the first stop movable part) 21, and a second rotating shaft part 38 to which the stop connection part 37 is fixed and which is rotatably connected to the car frame 11 about the first lateral direction D1. Such a configuration is preferable.

[0056] According to such a configuration, the first rotating shaft part 36 to which the force is transmitted from the governor rope 7a and the second rotating shaft part 38 that transmits the force to the stop movable part (in this embodiment, the first stop movable part) 21 can be made separate. And the operation connection part (in this embodiment, the first operation connection part) 33 connects the first rotating part 31 and the second rotating part 32.

[0057] Thereby, due to the governor rope 7a, the rope connection part 35 and the first rotating shaft part 36 rotate about the first lateral direction D1, so that the second rotating shaft part 38 and the stop connection part (in this embodiment, the first stop connection part) 37 rotate about the first lateral direction D1. Therefore, the stop movable part 21 moves from the standby position to the stop position.

[0058] In addition, since the second rotating shaft portion 38 is rotatably connected to the car frame 11 about the first lateral direction D1, when the rope connection portion 35 swings, the stop connection portion (in this embodiment, the first stop connection portion) 37 swings about the first lateral direction D1. Thereby, it is possible to suppress a change in the distance between the stop connection portion 37 and the car sheave (in this embodiment, the first car sheave) 12. Therefore, even when the rope connection portion 35 swings, it is possible to suppress the stop connection portion 37 from swinging so as to approach the car sheave 12.

[0059] [3] In the elevator car 10 of the above [2], as in this embodiment, the lower end of the car sheave (in this embodiment, the first car sheave) 12 is the lower end of the elevator car 10, and the upper end of the car sheave 12 is disposed above the second rotating shaft portion 38. Such a configuration is preferable.

[0060] According to such a configuration, since the upper end of the car sheave 12 is disposed above the second rotating shaft portion 38, it is possible to suppress the lower end of the car sheave 12 from being overly separated downward from the car frame 11. Thereby, it is possible to suppress the vertical dimension of the elevator car 10 from becoming too large.

[0061] [4] In the elevator car 10 of the above [3], as in this embodiment, a part of the car sheave (in this embodiment, the first car sheave) 12 is disposed outside the end position 11b in the second lateral direction D2 of the car frame 11, the second rotating shaft portion 38 is separated from the car sheave 12 when viewed in the second lateral direction D2 orthogonal to the first lateral direction D1, and the second rotating shaft portion 38 overlaps the car sheave 12 when viewed in the first lateral direction D1. Such a configuration is preferable.

[0062] According to such a configuration, since the second rotating shaft portion 38 overlaps with the car sheave 12 in the view in the first lateral direction D1, the second rotating shaft portion 38 is disposed in the region of the end portion in the second lateral direction D2 of the car frame 11. Thereby, it is possible to suppress the length of the stop connection portion (the first stop connection portion in this embodiment) 37 from becoming too long.

[0063] [5] Further, in any one of the elevator cars 10 of the above [2] to [4], as in this embodiment, the operation connection portion (the first operation connection portion in this embodiment) 33 is a first shaft fixing portion 39 fixed to the first rotating shaft portion 36, a second shaft fixing portion 40 fixed to the second rotating shaft portion 38, a fixed connection portion (the first fixed connection portion in this embodiment) 41 that is rotatably connected to the first shaft fixing portion 39 about the first lateral direction D1 at a first rotation center position 41a and is rotatably connected to the second shaft fixing portion 40 about the first lateral direction D1 at a second rotation center position 41b, and in the view in the first lateral direction D1, a straight line (the first straight line in this embodiment) L1 connecting the first rotation center position 41a and the first shaft center position 36a of the first rotating shaft portion 36 is parallel to a straight line (the second straight line in this embodiment) L2 connecting the second rotation center position 41b and the second shaft center position 38a of the second rotating shaft portion 38, in the view in the first lateral direction D1, a straight line (the third straight line in this embodiment) L3 connecting the first rotation center position 41a and the second rotation center position 41b is parallel to a straight line (the fourth straight line in this embodiment) L4 connecting the first shaft center position 36a and the second shaft center position 38a, such a configuration is preferable.

[0067] [7] Further, the elevator 1 preferably has, as in this embodiment, one of the elevator cars 10 in the above [1] to [6]. such a configuration is preferable.

[0068] According to such a configuration, even when the rope connection portion 35 swings with respect to the configuration in which the car sheave (in this embodiment, the first car sheave) 12 is disposed between the governor rope 7a and the stop movable portion (in this embodiment, the first stop movable portion) 21, it is possible to suppress the governor rope 7a from vibrating so as to approach the car rope 2.

[0069] Note that the elevator 1 and the elevator car 10 are not limited to the configurations of the above-described embodiments, nor are they limited to the above-described functions and effects. Further, the elevator 1 and the elevator car 10 can be variously modified without departing from the gist of the present invention.
