Description
Technical Field
The invention relates to an elevator, in particular to a three-side frame of an elevator.
Background
In an elevator, a wall of a hall is provided with three frames surrounding an opening which is an entrance of a car. Generally, a three-sided frame is configured by connecting an upper frame and a pair of vertical frames in a substantially コ -shape. Conventionally, the upper frame and the vertical frame are connected by bolts and nuts, and the connection portion between the upper frame and the vertical frame is formed by bending a flange or a bracket for fastening.
The three-side frame of the elevator is important in appearance in use. The appearance of the surfaces of the upper frame and the vertical frame constituting the triple frame is important, and a gap or a misalignment of the joint between the upper frame and the vertical frame is not allowed to occur at the portion where the upper frame and the vertical frame are coupled to each other. Therefore, in assembling the three-sided frame, it takes a lot of time to perform the connecting/adjusting operation for obtaining the appearance.
As an example of a three-sided frame of an elevator which is easy to assemble, patent document 1 discloses a three-sided frame having an engaging hole provided in an upper frame and an engaging piece provided in a vertical frame and plastically deformed at a position inserted into the engaging hole of the upper frame to fix the vertical frame and the upper frame to each other.

Disclosure of Invention
Technical problem to be solved by the invention
In assembling the three-sided frame of the elevator, if the vertical frame and the upper frame are fastened using bolts and nuts, there is a possibility that a gap is generated between the vertical frame and the upper frame or the vertical frame rotates during fastening, and it is difficult to determine and finely adjust the fixing position of the vertical frame and the upper frame. Therefore, the conventional elevator has the problems that the assembly operation of the three side frames is difficult and the assembly of the three side frames takes a lot of time.
The three-sided frame of the elevator described in patent document 1 does not use a bolt member for connecting the vertical frame and the upper frame. However, in the triple-frame disclosed in patent document 1, since the engaging piece extending from the design surface is bent or twisted in order to fix the vertical frame and the upper frame to each other, the design surface may be deformed, which may deteriorate the design.
The invention aims to provide an elevator with three side frames which do not cause reduction of appearance and are easy to assemble.
Technical problem to be solved by the invention
The elevator of the invention comprises: a car that ascends and descends in a hoistway; and a three-side frame provided in the hall so as to surround an opening for opening and closing the hall door, wherein the opening and closing direction of the hall door is a width direction, and a direction from the hall toward the hoistway is a depth direction. The three-frame has: a pair of vertical frames extending in the vertical direction; and an upper frame extending in the width direction and fixed to the pair of vertical frames at upper portions thereof. The pair of vertical frames each have: a first main surface facing the opening and orthogonal to the width direction; a first side surface which is connected to one end of the first main surface in the depth direction and is parallel to the width direction; a second side surface which is connected to the other end of the first main surface in the depth direction and is parallel to the width direction; a first folding surface which is connected to the first side surface and is orthogonal to the width direction; a second folded surface connected to the second side surface and orthogonal to the width direction; an upper surface orthogonal to the up-down direction; a first protrusion provided at an upper end of the first folded back surface and extending upward; and a second protrusion provided at an upper end of the second folded back surface and extending in an upward direction. The upper frame has a second main surface orthogonal to the vertical direction, and has, at each of both ends in the width direction: a first notch which is a recess provided at one end portion in the depth direction of the second main surface and recessed in the width direction, and which is capable of fitting with the first protrusion; and a second notch which is a recess provided at the other end portion in the depth direction of the second main surface and recessed in the width direction, and which is capable of fitting with the second protrusion. The width-direction depression length of the second notch is greater than the width-direction depression length of the first notch.

Detailed Description
Hereinafter, an elevator according to an embodiment of the present invention will be described with reference to the drawings. In the drawings used in the present specification, the same or corresponding components are denoted by the same reference numerals, and repetitive description thereof will be omitted.
Fig. 6 is a schematic diagram showing an outline of an elevator according to an embodiment of the present invention. The elevator 50 includes a car 30 that ascends and descends in a hoistway 40 provided in a building, a main rope 32 having one end connected to the car 30, a hoisting machine 31 that drives the main rope 32 to ascend and descend the car 30, and a counterweight 33 connected to the other end of the main rope 32. The car 30 has car doors 34. The elevator 50 has a hall door 3 for opening and closing an opening, which is an entrance of the car 30, and a three-sided frame 20 surrounding the opening at a hall 35.
The three-sided frame 20 of the elevator 50 will be explained. Hereinafter, the opening/closing direction of the hall doors 3 is defined as the width direction, and the direction from the hall 35 to the hoistway 40 is defined as the depth direction. The width direction and the depth direction are orthogonal to each other. The direction of the car 30 is the vertical direction.
Fig. 1 is a schematic diagram showing an outline of a three-sided frame 20 of an elevator 50 according to an embodiment of the present invention. The triple-frame 20 is a portal structure that is attached to a hall floor 1 (floor of a hall 35) and a wall 2 of a building and surrounds an opening 21 opened and closed by a hall door 3. The triple frame 20 has a pair of parallel vertical frames 4 and upper frames 5. The vertical frame 4 extends in the vertical direction. The upper frame 5 extends in the width direction and is fixed to the vertical frames 4 so as to connect the upper portions of the pair of vertical frames 4. Both the vertical frame 4 and the upper frame 5 are members formed by bending a metal plate.
Fig. 2 is a front view schematically showing the vertical frame 4 of the triple-frame 20. Fig. 3 is a top view schematically showing the vertical frame 4 of the triple-frame 20. As shown in fig. 2 and 3, the vertical frame 4 has a main surface 6, side surfaces 7a and 7b, folded surfaces 8a and 8b, and an upper surface 9 (flange 9). The upper surface 9 has fixing holes 10.
The main surface 6 is a surface extending in the vertical direction, facing the opening 21, and perpendicular to the width direction (i.e., a surface parallel to the depth direction). The side surfaces 7a and 7b are surfaces extending in the vertical direction and parallel to the width direction. The side surface 7a is connected to one end of the main surface 6 in the depth direction, and the side surface 7b is connected to the other end of the main surface 6 in the depth direction. The folded surfaces 8a and 8b are surfaces extending in the vertical direction and orthogonal to the width direction (i.e., surfaces parallel to the main surface 6). The folded surface 8a is connected to the side surface 7a, and the folded surface 8b is connected to the side surface 7 b. The upper surface 9 is a surface parallel to the hall floor 1 (i.e., a surface perpendicular to the vertical direction), and is connected to the main surface 6, the side surfaces 7a and 7b, and the folded surface 8b, as shown in fig. 3. The width (length in the width direction) W1 of the side face 7a is larger than the width W2 of the side face 7b (W1> W2).
In addition, one of the group of the side surface 7a and the folded surface 8a and the group of the side surface 7b and the folded surface 8b may be located on the hall 35 side and the other may be located on the hoistway 40 side, but either group may be located on the hall 35 side. When the group of side surface 7a and folded surface 8a is located on the hall 35 side, the side surface 7a wider than the side surface 7b is located on the hall 35 side, and the vertical frame 4 is easily attached to the wall 2, which is preferable.
As shown in fig. 2, the folded-back surface 8a has, at its upper end portion, a positioning protrusion 8a1 extending from the upper end portion in the longitudinal direction (upward direction) of the vertical frame 4. The folded back surface 8b has a rotation stopping protrusion 8b1 extending from the upper end portion in the longitudinal direction of the vertical frame 4 at the upper end portion thereof.
The positioning protrusion 8a1 and the rotation stopping protrusion 8b1 can be provided on the folded back surface 8a and the folded back surface 8b by 2 methods, for example. The first method is a method of manufacturing the protrusions 8a1 and 8b1 separately from the vertical frame 4 and attaching the manufactured protrusions 8a1 and 8b1 to the folded surfaces 8a and 8b, respectively. The second method is a method of providing the protrusions 8a1, 8b1 by molding (processing) the folded back surfaces 8a, 8b so that at least a part of the upper end portions of the folded back surfaces 8a, 8b extends upward when the vertical frame 4 is manufactured. The projections 8a1, 8b1 provided by the second method are convex portions in which at least a part of the upper end portions of the folded back surfaces 8a, 8b is extended upward. When the projections 8a1, 8b1 are provided on the folded back surfaces 8a, 8b by the second method, the projections 8a1, 8b1 can be manufactured integrally with the vertical frame 4, instead of attaching the projections 8a1, 8b1 manufactured in another step to the folded back surfaces 8a, 8 b. Therefore, when the protrusions 8a1, 8b1 are provided by the second method, the vertical frame 4 can be manufactured with high accuracy, and the three-sided frame 20 can be assembled with high accuracy.
Fig. 4 is a top view schematically showing the upper frame 5 of the triple-frame 20. As shown in fig. 4, the upper frame 5 has a main surface 11 and side surfaces 12a and 12 b. The main surface 11 is a surface extending in the width direction and parallel to the hall floor 1 (i.e., a surface perpendicular to the vertical direction). The side surfaces 12a and 12b are surfaces extending in the width direction, connected to the main surface 11, and parallel to the vertical direction (i.e., surfaces perpendicular to the hall floor 1). The side surface 12a is connected to one end of the main surface 11 in the depth direction, and the side surface 12b is connected to the other end of the main surface 11 in the depth direction.
The main surface 11 has a positioning notch 13, a rotation stop notch 14, and a fixing hole 15 at both ends in the width direction. The positioning notch 13 is a recess provided at one end in the depth direction of the main surface 11 and recessed in the width direction, and is fitted into the positioning protrusion 8a1 of the vertical frame 4. The rotation stopping notch 14 is a recess recessed in the width direction provided at the other end portion in the depth direction of the main surface 11, and is fitted into the rotation stopping protrusion 8b1 of the vertical frame 4. The fixing hole 15 is provided at a position vertically opposed to the fixing hole 10 (fig. 3) of the vertical frame 4. Bolts are inserted into the fixing holes 15 of the upper frame 5 and the fixing holes 10 of the vertical frame 4 to fasten the upper frame 5 and the vertical frame 4 together.
The positioning projection 8a1 of the vertical frame 4 is fitted into the positioning notch 13. Accordingly, the positioning notch 13 is located at the end of the main surface 11 on the hall 35 side when the folded-back surface 8a of the vertical frame 4 is located on the hall 35 side, and is located at the end of the main surface 11 on the hoistway 40 side when the folded-back surface 8a of the vertical frame 4 is located on the hoistway 40 side.
The rotation stopping projection 8b1 of the vertical frame 4 is fitted into the rotation stopping notch 14. Accordingly, the rotation stopping notch 14 is located at the end of the main surface 11 on the hall 35 side when the folded-back surface 8b of the vertical frame 4 is located on the hall 35 side, and is located at the end of the main surface 11 on the hoistway 40 side when the folded-back surface 8b of the vertical frame 4 is located on the hoistway 40 side.
The depth (the length of the recess in the width direction) of the positioning notch 13 is denoted by D1, and the depth of the detent notch 14 is denoted by D2. The depth D2 of the notch of the rotation stopper notch 14 is greater than the depth D1 of the notch of the positioning notch 13 (D2> D1).
In the elevator 50 of the present embodiment, the positioning protrusion 8a1 and the rotation stopping protrusion 8b1 of the vertical frame 4 of the three-sided frame 20 are fitted in the positioning notch 13 and the rotation stopping notch 14 of the upper frame 5, respectively. The upper frame 5 has notches 13 and 14, instead of holes, for fitting the projections 8a1 and 8b 1. If the upper frame 5 has holes into which the protrusions 8a1, 8b1 are fitted, the holes must be opened largely in consideration of dimensional errors in manufacturing of the protrusions 8a1, 8b1, and the vertical frame 4 and the upper frame 5 must be combined in consideration of the size of the holes. In this embodiment, since the upper frame 5 has the notches 13 and 14 and the projections 8a1 and 8b1 of the vertical frame 4 are fitted into the notches 13 and 14, the vertical frame 4 and the upper frame 5 can be combined without considering the dimensional errors of the projections 8a1 and 8b 1.
Fig. 5 is a view schematically showing a junction between the vertical frame 4 and the upper frame 5 of the three-side frame 20 of the elevator 50 in an expanded state.
In the three-sided frame 20, the position in the width direction of the positioning protrusion 8a1 of the vertical frame 4 is determined by the position in the width direction of the vertical frame 4 and the width W1 of the side surface 7a, and the position in the width direction of the rotation stopping protrusion 8b1 is determined by the position in the width direction of the vertical frame 4 and the width W2 of the side surface 7 b. The sizes of the width W1 and the width W2 are determined so as to satisfy the relationship W1> W2, based on the strength required for the vertical frame 4. The width of the side surface of the side surfaces 7a and 7b located on the entrance 35 side may be determined based on the requirement for the appearance.
The depth D1 of the notch of the positioning notch 13 and the depth D2 of the notch of the rotation-stopping notch 14 of the upper frame 5 (fig. 4) are determined so that the positioning protrusion 8a1 of the vertical frame 4 (fig. 3) fits into the positioning notch 13 and the rotation-stopping protrusion 8b1 of the vertical frame 4 fits into the rotation-stopping notch 14. The depth D1 of the positioning notch 13 can be set to be substantially the same as the thickness (length in the width direction) of the folded surface 8a of the vertical frame 4.
The depth direction length of the positioning notch 13 is substantially the same as the depth direction length of the positioning protrusion 8a1 of the vertical frame 4 (fig. 3 and 4). The length of the rotation stopping notch 14 in the depth direction is substantially the same as the length of the rotation stopping protrusion 8b1 of the vertical frame 4 in the depth direction.
As shown in fig. 4, the notch depth D2 of the rotation stop notch 14 is greater than the notch depth D1 of the positioning notch 13. Therefore, even if a rotational force in the vertical direction is applied to the vertical frame 4 in the axial direction when the vertical frame 4 and the upper frame 5 are fastened to each other, the rotation preventing projection 8b1 of the vertical frame 4 does not come off the rotation preventing notch 14 but fits into the rotation preventing notch 14, and thus the vertical frame 4 can be prevented from rotating, and the fixing strength between the vertical frame 4 and the upper frame 5 can be improved.
Since the depth D2 of the notch up to the turning notch 14 is greater than the depth D1 of the notch of the positioning notch 13 (D2> D1), as shown in fig. 3, the width W2 of the side surface 7b connected to the folded back surface 8b is smaller than the width W1 of the side surface 7a connected to the folded back surface 8a (W1> W2). With this configuration, the positioning projection 8a1 is fitted into the positioning notch 13, and the rotation stopping projection 8b1 is fitted into the rotation stopping notch 14. Therefore, the position where the rotation stopping protrusion 8b1 fits in the rotation stopping notch 14 is closer to the opening 21 in the width direction than the position where the positioning protrusion 8a1 fits in the positioning notch 13.
By configuring the vertical frame 4 and the upper frame 5 in this manner, when the vertical frame 4 and the upper frame 5 are combined with each other, the positioning projection 8a1 can be prevented from coming off the positioning notch 13, and even if a rotational force in the vertical direction as an axial direction is applied to the vertical frame 4 when the vertical frame 4 and the upper frame 5 are fastened, the vertical frame 4 can be prevented from rotating. Therefore, in the elevator 50 of the present embodiment, the three-sided frames 20 can be easily assembled, and the time required for assembling the three-sided frames 20 can be reduced.
The main purpose of fitting the positioning protrusion 8a1 and the positioning notch 13 is to determine the position in the width direction of the vertical frame 4 during assembly, and the main purpose of fitting the rotation stopping protrusion 8b1 and the rotation stopping notch 14 is to prevent rotation of the vertical frame 4 during assembly. Therefore, the size and shape of the rotation stopping protrusion 8b1 and the rotation stopping notch 14 may not be strictly determined, unlike the positioning protrusion 8a1 and the positioning notch 13 that reflect the position in the width direction of the vertical frame 4.
The fixing hole 15 (fig. 4) provided in the main surface 11 of the upper frame 5 is preferably located at one end in the depth direction (the end provided with the positioning notch 13) of the center in the depth direction of the main surface 11, and more preferably located within the range described below. That is, at least a part of the fixing hole 15 is more preferably located within a range Ra (fig. 4) extending the range in which the positioning notch 13 is located in the width direction.
The fixing hole 10 (fig. 3) provided in the upper surface 9 of the vertical frame 4 is provided at a position vertically opposed to the fixing hole 15 of the upper frame 5. Therefore, the position of the fixing hole 10 in the depth direction is preferably located closer to the side surface 7a than the center of the upper surface 9 in the depth direction, and at least a part of the fixing hole is more preferably located within a range Rb (fig. 3) extending the range in which the positioning protrusion 8a1 is located in the width direction.
The fixing holes 15 and the fixing holes 10 are provided at positions of shafts when the vertical frame 4 rotates during fastening, and bolts are inserted into the fixing holes to fasten the upper frame 5 to the vertical frame 4. Therefore, the fixing hole 15 and the fixing hole 10 are preferably located at positions away from the rotation stop notch 14 and the rotation stop protrusion 8b 1. In consideration of the strength at the time of fastening, the punching work, and the like, it is more preferable that at least a part of each of the fixing hole 15 and the fixing hole 10 is located within the ranges Ra and Rb in which the existing ranges of the positioning notch 13 and the positioning protrusion 8a1 are extended in the width direction.
As shown in fig. 5, when the three-sided frame 20 is assembled, the positioning projection 8a1 of the vertical frame 4 is fitted into the positioning notch 13 of the upper frame 5 to determine the position of the vertical frame 4 in the width direction, and the rotation-stopping projection 8b1 of the vertical frame 4 is fitted into the rotation-stopping notch 14 of the upper frame 5. When the vertical frame 4 and the upper frame 5 are combined in this way, the fixing holes 10 provided in the upper surface 9 of the vertical frame 4 face the fixing holes 15 provided in the main surface 11 of the upper frame 5.
Subsequently, bolts, not shown, are inserted through the fixing holes 10 and the fixing holes 15, and the vertical frame 4 and the upper frame 5 are temporarily fixed to each other by half-fastening the bolts and nuts, not shown. Semi-fastening means not being completely fastened but being fastened in such a way that it can easily be loosened, quasi-fixing means fixing by semi-fastening.
The fine adjustment of the positions of the vertical frame 4 and the upper frame 5 is performed in a state where the vertical frame 4 and the upper frame 5 are quasi-fixed. Subsequently, the vertical frame 4 and the upper frame 5 are fixed to each other by fastening with bolts and nuts. In this fastening operation, although a rotational force is applied to the vertical frame 4, the rotation preventing projection 8b1 of the vertical frame 4 is fitted into the rotation preventing notch 14 of the upper frame 5, and therefore the vertical frame 4 can be prevented from rotating.
In addition, if the upper end of the positioning protrusion 8a1 protrudes from the upper end of the positioning notch 13 and the upper end of the rotation stopping protrusion 8b1 protrudes from the upper end of the rotation stopping notch 14 in a state where the positioning protrusion 8a1 of the vertical frame 4 is fitted into the positioning notch 13 of the upper frame 5 and the rotation stopping protrusion 8b1 of the vertical frame 4 is fitted into the rotation stopping notch 14 of the upper frame 5, the upper end of the positioning protrusion 8a1 and the upper end of the rotation stopping protrusion 8b1 can be bent. That is, the positioning projection 8a1 and the rotation stopping projection 8b1 can be bent at their upper ends and fitted into the positioning notch 13 and the rotation stopping notch 14, respectively, to fix the vertical frame 4 and the upper frame 5 to each other.
In the elevator 50 of the present embodiment, the three-sided frame 20 basically fixes the vertical frame 4 and the upper frame 5 to each other by fastening with bolts and nuts inserted through the fixing holes 10 and the fixing holes 15. Therefore, the main surfaces 6 and 11 of the vertical frames 4 and the upper frame 5, which are the appearance surfaces, are not deformed, and the appearance of the triple-frame structure 20 is not degraded. Further, since the positioning protrusion 8a1 and the rotation stopping protrusion 8b1 are provided on the folded back surfaces 8a and 8b, which are different surfaces from the main surface 6 of the vertical frame 4, even when the upper end portions of the positioning protrusion 8a1 and the rotation stopping protrusion 8b1 are bent, the main surface 6 is not deformed, and the appearance of the three-sided frame 20 is not degraded.
When the three-sided frame 20 is installed in the entrance 35, the positioning notch 13 and the rotation stopping notch 14 cannot be seen due to the wall 2 for installing the three-sided frame 20. Therefore, the positioning notch 13 and the rotation stopping notch 14 do not degrade the appearance of the three-sided frame 20.
In the elevator 50 of the present embodiment, when the three-sided frame 20 is assembled, the positioning protrusion 8a1 is fitted into the positioning notch 13 to determine the position of the vertical frame 4 in the width direction, and the vertical frame 4 and the upper frame 5 are fixed in alignment with each other to finely adjust the positions of the vertical frame 4 and the upper frame 5, so that the positioning (assembling) operation of the vertical frame 4 and the upper frame 5 is facilitated. In general, in the positioning work of the vertical frame 4 and the upper frame 5, fine adjustment of the position is performed at a high position, and therefore, the ease of the work is very important. In the elevator 50 of the present embodiment, since fine adjustment of the position is performed after the vertical frame 4 and the upper frame 5 are aligned and fixed to each other, the position adjustment of the vertical frame 4 and the upper frame 5 is easier than the case where the vertical frame 4 and the upper frame 5 are fixed without alignment.
When the vertical frame 4 and the upper frame 5 are fastened and fixed by bolts and nuts, a rotational force is applied to the vertical frame 4, but since the rotation preventing projection 8b1 of the vertical frame 4 is fitted into the rotation preventing notch 14 of the upper frame 5, the vertical frame 4 can be prevented from rotating even if an operator does not hold down the vertical frame with the hand. Further, the vertical frame 4 and the upper frame 5 can be fixed to each other by fastening only 1 portion at one end in the width direction with bolts and nuts. Therefore, in the elevator 50 of the present embodiment, the workability of assembling the vertical frame 4 and the upper frame 5 of the three-sided frame 20 is excellent, and the number of bolts required for assembling can be reduced.
As described above, in the elevator 50 of the present embodiment, the three-sided frames 20 can be easily assembled without causing a reduction in appearance, and the time required for assembling the three-sided frames 20 can be reduced.
