Summary of the Invention

Problems to be Solved by the Invention

[0004] However, particularly in high-rise buildings and the like, the cable is greatly affected by wind, and there is a possibility that the cable is blown by the wind and deviates from a predetermined position.

[0005] Therefore, in view of the above circumstances, the present invention provides a cable regulating member for a construction elevator and a construction elevator that can regulate the position of the cable.

Means for Solving the Problems

[0006] To achieve the above object, the present invention employs the following means. In other words, the cable regulating member for a construction elevator according to the present invention is frame-shaped in plan view and comprises a frame-shaped portion having a cable arrangement space portion formed inside in which a cable extending vertically can be arranged, an opening formed in the frame-shaped portion that communicates the cable arrangement space portion with the outside, and a closing portion that can open and close the opening, wherein the closing portion is provided at both ends of the frame-shaped portion in which the opening is formed and has a pair of elastically deformable regulating portions, and the regulating portions have an arc portion that bulges in the middle of the vertical direction toward the end opposite to the end of the opening in which the regulating portion is provided. Furthermore, the pair of restricting portions are arranged with a gap between them in the direction connecting the cable arrangement space and the outside, with the opening in between. .

[0007] In the cable regulating member of the construction elevator configured in this way, the pair of regulating parts positioned at the opening each have an arc-shaped portion that bulges outwards from the end of the opening to the opposite end in the vertical middle section. Therefore, even if a force acts on the cable toward the outside of the opening, the pair of regulating parts resist it, preventing the cable from moving out of the cable placement space and thus regulating the cable's position.

[0008] Furthermore, in the cable regulating member for a construction elevator according to the present invention, the pair of regulating parts may be arranged with a gap between them in the direction connecting the cable arrangement space and the outside, with the opening in between.

[0009] In the cable regulating member of the construction elevator configured in this way, the pair of regulating parts are positioned with a gap between them in the direction connecting the cable arrangement space and the outside, with the opening in between. Therefore, when the cable tail end passes through, it can push the pair of regulating parts aside in the vertical direction, allowing it to pass through.

[0010] Furthermore, in the cable regulating member for a construction elevator according to the present invention, the pair of regulating parts may be arranged to overlap when viewed from the direction connecting the cable arrangement space and the outside with the opening in between.

[0011] In the cable regulating member of the construction elevator configured in this way, the pair of regulating parts are arranged to overlap when viewed from the direction connecting the cable arrangement space and the outside, with the opening in between. Because the pair of regulating parts are arranged in a double configuration in the direction connecting the cable arrangement space and the outside, with the opening in between, the movement of the cable from the cable arrangement space can be further restricted.

[0012] Furthermore, in the cable regulating member for the construction elevator according to the present invention, The device comprises a frame-shaped portion in plan view, having a cable arrangement space portion formed inside which vertically extending cables can be arranged; an opening formed in the frame-shaped portion that connects the cable arrangement space portion to the outside; and a closing portion that can open and close the opening, wherein the closing portion has a pair of elastically deformable restricting portions provided at both ends of the frame-shaped portion where the opening is formed, and the restricting portions have an arc portion that bulges in the vertical middle portion toward the end of the opening opposite to the end of the opening where the restricting portion is provided. The pair of restricting parts may be in contact in the vertical direction.

[0013] In the cable regulating member of the construction elevator configured in this way, the pair of regulating parts are in contact in the vertical direction. Therefore, since the pair of regulating parts are arranged in double contact in the vertical direction, it is possible to further restrict the movement of the cable from the cable placement space.

[0014] Furthermore, in the cable regulating member for the construction elevator according to the present invention, The device comprises a frame-shaped portion in plan view, having a cable arrangement space portion formed inside which vertically extending cables can be arranged; an opening formed in the frame-shaped portion that connects the cable arrangement space portion to the outside; and a closing portion that can open and close the opening, wherein the closing portion has a pair of elastically deformable restricting portions provided at both ends of the frame-shaped portion where the opening is formed, and the restricting portions have an arc portion that bulges in the vertical middle portion toward the end of the opening opposite to the end of the opening where the restricting portion is provided. The pair of arc portions may be in contact in a direction connecting the ends on both sides of the opening.

[0015] In the cable regulating member of the construction elevator configured in this way, the pair of arc-shaped sections are in contact in the direction connecting the ends on both sides of the opening. Therefore, the contacting pair of arc-shaped sections can further restrict the movement of the cable from the cable placement space.

[0016] Furthermore, the construction elevator according to the present invention comprises a cable regulating member according to any one of the above-mentioned items, a cable end portion connected to the elevator body and passing through the opening, and a cable connected to the cable end portion and arranged in the cable arrangement space.

[0017] In the construction elevator configured as described above, the pair of restricting portions arranged at the opening each have an arc portion that bulges toward the end opposite to the end of the opening. The pair of restricting portions are in contact with each other. Therefore, even if a force acting outward from the opening on the cable is applied, the pair of restricting portions resist it, so that the cable does not move from the cable arrangement space portion, and the position of the cable can be restricted.

Effect of the Invention

[0018] According to the cable restricting member and the construction elevator of the construction elevator according to the present invention, the position of the cable can be restricted.

[0020] (First Embodiment) A construction elevator according to the first embodiment of the present invention will be described with reference to the drawings. Figure 1 shows the configuration of a construction elevator according to the first embodiment of the present invention. As shown in Figure 1, the construction elevator 100 comprises an elevator guide rail 11, an elevator body 13, a movable pulley rail 15, a cable end portion 21, a cable 22, a movable pulley for the cable 25, a cable return member 26, and a cable regulating member (a cable regulating member for the construction elevator) 3.

[0021] In the following explanation, a direction along the horizontal plane will be denoted as the first direction X. A direction along the horizontal plane perpendicular to the first direction will be denoted as the second direction Y. The vertical direction will be denoted as the vertical direction Z.

[0022] The elevator guide rails 11 are provided in pairs, separated in the first direction X. Figure 1 shows only one of the elevator guide rails 11. The elevator guide rails 11 are members that are long in the vertical direction Z. For example, the elevator guide rails 11 are constructed by joining steel members.

[0023] The elevator body 13 is capable of housing building materials and other components inside. Guide members 13a, provided on both sides of the elevator body 13 in a first direction X, are each supported by a pair of elevator guide rails 11. Figure 1 shows one side of the elevator body 13 in the first direction X. The elevator body 13 is configured to be movable in the vertical direction Z along the elevator guide rails 11.

[0024] The movable pulley rail 15 is a member that is long in the vertical direction Z. For example, the movable pulley rail 15 is constructed by joining steel materials together.

[0025] The cable end portion 21 is connected to the elevator body 13. In a plan view, the cable end portion 21 extends from the top of the elevator body 13 towards the movable pulley rail 15.

[0026] Cable 22 is connected to the cable end portion 21. Cable 22 is a long component.

[0027] The cable pulley 25 is wound around the cable 22. The cable pulley 25 is supported on the pulley rail 15 so as to be movable in the vertical Z direction.

[0028] The cable return member 26 is fixed to the upper part of the elevator guide rail 11. The cable 22 is wound around the cable return member 26.

[0029] Figure 3 is a perspective view showing the cable regulating member 3. Figure 4 is a view taken along arrow IV in Figure 3. Figure 5 is a view taken along arrow V in Figure 3. Figure 6 is a view taken along arrow V in Figure 3. As shown in Figures 3 to 6, the cable regulating member 3 comprises a fixing portion 30 and a surrounding portion 40.

[0030] The fixing part 30 can be fixed to the movable pulley rail 15 shown in Figure 1. As shown in Figure 3, the fixing part 30 has a vertical member 31 and a horizontal member 32.

[0031] The vertical members 31 extend in the vertical direction Z. The vertical members 31 are arranged in pairs, separated in the first direction X. The vertical members 31 are members with an L-shaped horizontal cross-section. Mounting holes 311 are formed in the vertical members 31, penetrating in the second direction Y. There are four mounting holes 311, spaced apart in the vertical direction Z. As shown in Figure 5, bolts 312 are inserted through the mounting holes 311 and fastened to the movable pulley rail 15 with nuts (not shown).

[0032] As shown in Figure 3, the horizontal member 32 connects the upper parts of the pair of vertical members 31. The horizontal member 32 extends in the first direction X. The horizontal member 32 is a cylindrical member. The fixing part 30 only needs to be able to be fixed to the movable pulley rail 15, and the configuration of the fixing part 30 can be set as appropriate.

[0033] The surrounding portion 40 has a frame-shaped portion 41, an opening S2, and a closing portion 45.

[0034] The frame-shaped portion 41 is a member formed in the shape of a frame when viewed from above. The frame-shaped portion 41 has a first frame member 411, a second frame member 412, and a third frame member 413. In the first direction X, the side on which the opening S2 is located is called the X1 side, and the side opposite to the opening S2 is called the X2 side.

[0035] The first frame member 411 connects the lower parts of a pair of vertical members 31. The first frame member 411 is a cylindrical member. The second frame member 412 extends toward the X1 side from the lower part of one of the vertical members 31 that is positioned on the X1 side. The second frame member 412 is a cylindrical member. The third frame member 413 extends toward the X2 side from the lower part of the vertical member 31 that is positioned on the X2 side of the pair of vertical members 31, and is formed to curve in an arc shape so as to bulge toward the X2 side and extend toward the X1 side. The portion of the third frame member 413 that faces the first frame member 411 and the second frame member 412 in the second direction Y is designated as the third frame member opposing portion 414. In plan view, the frame portion 41 is U-shaped and opens toward the X1 side. The frame portion 41 may also be rectangular and open toward the X1 side, and the shape of the frame portion 41 can be set as appropriate.

[0036] As shown in Figure 5, a space is formed inside the frame-shaped portion 41 that opens to the X1 side through an opening S2. The space inside the frame-shaped portion 41 is the cable arrangement space S1. A cable 22 extending in the vertical direction Z is arranged in the cable arrangement space S1.

[0037] The opening S2 is a space formed between the X1-side end 412a of the second frame member 412 of the frame-shaped portion 41 and the X1-side end 414a of the third frame member opposing portion 414. The opening S2 connects the cable arrangement space S1 to the outside. The outside refers to the space other than the frame-shaped portion 41, enclosed by the frame-shaped portion 41, in a plan view.

[0038] A first upper fixing portion 421 is provided at the end 412a of the second frame member 412. A second upper fixing portion 431 is provided at the end 414a of the third frame member opposing portion 414.

[0039] The closing section 45 closes the opening S2 so that it can be opened and closed. The closing section 45 has a pair of restricting sections 46. One restricting section 46 is provided on the first upper fixing section 421. The other restricting section 46 is provided on the second upper fixing section 431. In the normal state when no force is acting on the pair of restricting sections 46, the pair of restricting sections 46 closes the opening S2. The frame-shaped section 41 and the pair of restricting sections 46 make the cable arrangement space S1 a closed space that does not communicate with the outside.

[0040] The restricting portion 46 is made of an elastically deformable material such as rubber. As shown in Figure 3, the restricting portion 46 has a pair of straight portions 461 and an arc portion 462. A plate-shaped member is processed to form the pair of straight portions 461 and the arc portion 462. The pair of straight portions 461 are spaced apart in the vertical direction Z. The plate surface of the straight portions 461 faces the vertical direction Z.

[0041] In the restricting portion 46 provided on the first upper fixing portion 421, the end of the upper straight portion 461 of the pair of straight portions 461 is positioned below the first upper fixing portion 421. A spacer 48 is positioned between the ends of the pair of straight portions 461. The first lower fixing portion 422 is positioned below the lower straight portion 461 of the pair of straight portions 461. A bolt 423 is inserted through the first upper fixing portion 421, the upper straight portion 461, the spacer 48, the lower straight portion 461, and the first lower fixing portion 422, and fastened with a nut 424. In this way, the pair of straight portions 461 are fixed to the end portion 412a of the second frame member 412 with a gap between them vertically. The pair of straight portions 461 extending from the end portion 412a of the second frame member 412 are connected by an arc portion 462. The arc portion 462 bulges outwards from the end portion 412a that forms the opening S2 to the end portion 414a opposite to the end portion 414a at the midpoint of the vertical Z direction of the restricting portion 46. The plate surface of the arc portion 462 faces the second direction Y.

[0042] In the restricting portion 46 provided on the second upper fixing portion 431, the end of the upper straight portion 461 of the pair of straight portions 461 is positioned below the second upper fixing portion 431. A spacer 48 is positioned between the ends of the pair of straight portions 461. The second lower fixing portion 432 is positioned below the lower straight portion 461 of the pair of straight portions 461. A bolt 433 is inserted through the second upper fixing portion 431, the upper straight portion 461, the spacer 48, the lower straight portion 461, and the second lower fixing portion 432, and fastened with a nut 434. As a result, the pair of straight portions 461 are fixed to the end portion 414a of the third frame member opposing portion 414 with a gap between them vertically. The pair of straight portions 461 extending from the end portion 414a of the third frame member opposing portion 414 are connected by an arc portion 462. The arc portion 462 bulges outwards from the end portion 414a that forms the opening S2 to the end portion 412a opposite to the end portion 412a at the midpoint of the vertical Z direction of the restricting portion 46. The plate surface of the arc portion 462 faces the second direction Y.

[0043] The restricting portion 46 fixed to the end 414a of the third frame member opposing portion 414 is positioned closer to the cable arrangement space S1 than the restricting portion 46 fixed to the end 412a of the second frame member 412. The restricting portion 46 fixed to the end 412a of the second frame member 412 is positioned further outside the cable arrangement space S1 than the restricting portion 46 fixed to the end 414a of the third frame member opposing portion 414. The arc portion 462 of the restricting portion 46 fixed to the end 412a of the second frame member 412 is positioned closer to the end 414a of the third frame member opposing portion 414 than the arc portion 462 of the restricting portion 46 fixed to the end 414a of the third frame member opposing portion 414. The arc portion 462 of the restricting portion 46 fixed to the end portion 414a of the third frame member opposing portion 414 is positioned closer to the end portion 412a of the second frame member 412 than the arc portion 462 of the restricting portion 46 fixed to the end portion 412a of the second frame member 412.

[0044] The pair of restricting sections 46 are arranged with a gap between them. The straight sections 461 of the pair of restricting sections 46 are arranged with a gap between them in the first direction X. The straight sections 461 of the pair of restricting sections 46 are arranged with a gap between them in the direction connecting the cable arrangement space S1 and the outside, with the opening S2 in between. This gap is, for example, about 10 mm. The dimensions of the gap can be appropriately set according to the material of the restricting section 46, the elastic modulus, the dimension in the X direction, etc.

[0045] The pair of restricting sections 46 are arranged to overlap when viewed from the first direction X. The straight section 461 of one restricting section 46 and the straight section 461 of the other restricting section 46 are arranged to overlap when viewed from the first direction X.

[0046] As shown in Figure 5, the cable end portion 21 can be positioned in the opening S2 so as to pass between the outside and the cable arrangement space S1. As the elevator body 13 moves in the vertical direction Z, the cable end portion 21 pushes aside the pair of restricting portions 46 in the vertical direction Z, allowing it to pass through the opening S2 and the cable arrangement space S1.

[0047] The portions of the cable 22 that are wound around the cable pulley 25 in the first direction X are located in the cable arrangement space S1. Even if a force from the X1 side acts on the cable 22 and the cable 22 pushes the pair of restricting parts 46 towards the X1 side, the pair of restricting parts 46 resist, thus restricting the cable 22 from moving out of the opening S2.

[0048] In the construction elevator 100 configured in this way, the pair of restricting parts 46 positioned in the opening S2 each have an arc-shaped portion 462 that bulges outwards toward the end of the opening S2 and the opposite end at the midpoint in the vertical direction Z. Therefore, even if a force acts on the cable 22 toward the outside of the opening S2, the pair of restricting parts 46 resist it, preventing the cable 22 from moving out of the cable arrangement space S1, and thus regulating the position of the cable 22.

[0049] Furthermore, the pair of restricting sections 46 are positioned with a gap between them in the direction connecting the cable arrangement space S1 and the outside, with the opening S2 in between. Therefore, when the cable end section 21 passes through the opening S2, it pushes the pair of restricting sections 46 vertically aside, allowing it to pass through. Also, since the pair of restricting sections 46 do not interfere with each other, after being displaced vertically, the pair of restricting sections 46 can return to their original positions after the cable end section 21 has passed through.

[0050] Furthermore, the pair of restricting sections 46 are arranged to overlap when viewed from the first direction X. Therefore, since the pair of restricting sections 46 are arranged in a double configuration in the first direction X, the movement of the cable 22 from the cable arrangement space S1 can be further restricted.

[0051] (Second embodiment) Next, a second embodiment of the present invention will be described mainly with reference to Figures 7 to 10. In the following description of the embodiment, the same reference numerals will be used for members and parts that are the same as or similar to those in the above-described embodiment, and their descriptions will be omitted. Configurations that differ from the embodiment will be described.

[0052] Figure 7 is a perspective view showing a cable regulating member of a construction elevator according to a second embodiment of the present invention. Figure 8 is a view taken along arrow VIII in Figure 7. Figure 9 is a view taken along arrow IX in Figure 7. Figure 10 is a view taken along arrow X in Figure 7.

[0053] As shown in Figures 7 to 10, in the cable regulating member 3A of this embodiment, the regulating portion 46 provided at the end 412a of the second frame member 412 and the regulating portion 46 provided at the end 414a of the third frame member opposing portion 414 are positioned with a vertical Z offset.

[0054] A first lower fixing portion 422 is provided at the end 412a of the second frame member 412. Above the first lower fixing portion 422 is the lower of a pair of straight sections 461. Above the lower straight section 461 is a spacer 48. Above the spacer 48 is the upper of a pair of straight sections 461. Above the upper straight section 461 is a first upper fixing portion 421. A bolt 423 is inserted through the first lower fixing portion 422, the lower straight section 461, the spacer 48, the upper straight section 461, and the first upper fixing portion 421, and fastened with a nut 424.

[0055] A second upper fixing portion 431 is provided at the end 414a of the third frame member opposing portion 414. Below the second upper fixing portion 431 is the upper of a pair of straight portions 461, which is the upper straight portion 461. Below the upper straight portion 461 is a spacer 48. Below the spacer 48 is the lower of a pair of straight portions 461, which is the lower straight portion 461. Below the lower straight portion 461 is a second lower fixing portion 432. A bolt 433 is inserted through the second upper fixing portion 431, the upper straight portion 461, the spacer 48, the lower straight portion 461, and the second lower fixing portion 432, and fastened with a nut 434.

[0056] A pair of restricting portions 46 are positioned in the opening S2. The restricting portion 46 provided at the end 412a of the second frame member 412 is positioned above the restricting portion 46 provided at the end 414a of the third frame member opposing portion 414. The arc portion 462 of the restricting portion 46 fixed to the end 412a of the second frame member 412 is positioned closer to the end 414a of the third frame member opposing portion 414 than the arc portion 462 of the restricting portion 46 fixed to the end 414a of the third frame member opposing portion 414. The arc portion 462 of the restricting portion 46 fixed to the end 414a of the third frame member opposing portion 414 is positioned closer to the end 412a of the second frame member 412 than the arc portion 462 of the restricting portion 46 fixed to the end 412a of the second frame member 412.

[0057] The pair of restricting parts 46 are in contact with each other. The pair of restricting parts 46 are in contact in the vertical direction Z. The lower straight section 461 of the upper restricting part 46 is in contact with the upper straight section 461 of the lower restricting part 46.

[0058] In the construction elevator 100 configured in this way, the pair of restricting parts 46 positioned in the opening S2 each have an arc-shaped portion 462 that bulges outwards from one end of the opening S2 to the opposite end at the midpoint in the vertical direction Z. Therefore, even if a force acts on the cable 22 toward the outside of the opening S2, the pair of restricting parts 46 resist it, preventing the cable 22 from moving out of the cable arrangement space S1, and thus regulating the position of the cable 22.

[0059] Furthermore, the pair of restricting parts 46 are in contact with each other in the vertical direction Z. Therefore, since the pair of restricting parts 46 are arranged in double contact with each other in the vertical direction Z, the movement of the cable 22 from the cable arrangement space S1 can be further restricted.

[0060] (Third embodiment) Next, a third embodiment of the present invention will be described mainly with reference to Figures 11 to 14.

[0061] Figure 11 is a perspective view showing a cable regulating member of a construction elevator according to a third embodiment of the present invention. Figure 12 is a view taken along arrow XII in Figure 11. Figure 13 is a view taken along arrow XIII in Figure 11. Figure 14 is a view taken along arrow XIV in Figure 11.

[0062] As shown in Figures 11 to 14, in the cable regulating member 3B of this embodiment, the regulating portion 46 provided at the end 412a of the second frame member 412 and the regulating portion 46 provided at the end 414a of the third frame member opposing portion 414 are located at the same position in the vertical Z direction and are arranged opposite to each other.

[0063] A first upper fixing portion 421 is provided at the end 412a of the second frame member 412. Below the first upper fixing portion 421 is the upper of a pair of straight portions 461, the upper straight portion 461. Below the upper straight portion 461 is a spacer 48. Below the spacer 48 is the lower of a pair of straight portions 461, the lower straight portion 461. Below the lower straight portion 461 is a first lower fixing portion 422. A bolt 423 is inserted through the first upper fixing portion 421, the upper straight portion 461, the spacer 48, the lower straight portion 461, and the first lower fixing portion 422, and fastened with a nut 424.

[0064] A second upper fixing portion 431 is provided at the end 414a of the third frame member opposing portion 414. Below the second upper fixing portion 431 is the upper of a pair of straight portions 461, which is the upper straight portion 461. Below the upper straight portion 461 is a spacer 48. Below the spacer 48 is the lower of a pair of straight portions 461, which is the lower straight portion 461. Below the lower straight portion 461 is a second lower fixing portion 432. A bolt 433 is inserted through the second upper fixing portion 431, the upper straight portion 461, the spacer 48, the lower straight portion 461, and the second lower fixing portion 432, and fastened with a nut 434.

[0065] The pair of restricting sections 46 are positioned in the opening S2. The restricting section 46 provided at the end 412a of the second frame member 412 and the restricting section 46 provided at the end 414a of the third frame member opposing section 414 are positioned at the same height.

[0066] The pair of restricting portions 46 are in contact with each other. The pair of restricting portions 46 are in contact in the direction connecting the end portion 412a of the second frame member 412 and the end portion 414a of the third frame member opposing portion 414. The arc portion 462 of one restricting portion 46 and the arc portion 462 of the other restricting portion 46 are in contact in the second direction Y.

[0067] In the construction elevator 100 configured in this way, the pair of restricting parts 46 positioned in the opening S2 each have an arc-shaped portion 462 that bulges outwards from one end of the opening S2 to the opposite end at the midpoint in the vertical direction Z. Therefore, even if a force acts on the cable 22 toward the outside of the opening S2, the pair of restricting parts 46 resist it, preventing the cable 22 from moving out of the cable arrangement space S1, and thus regulating the position of the cable 22.

[0068] Furthermore, the pair of arc-shaped portions 462 are in contact with the ends of the frame-shaped portion 41 in a direction that connects the ends on both sides. Therefore, the contacting pair of arc-shaped portions 462 can further restrict the movement of the cable 22 from the cable arrangement space S1.

[0069] It should be noted that the shapes and combinations of the constituent members shown in the above-described embodiments are merely examples, and can be modified in various ways based on design requirements, etc., without departing from the spirit of the present invention.

[0070] For example, in the embodiment shown above, in the first embodiment, a pair of restricting parts 46 are arranged side by side in the first direction X, but this is not limited to this. Three or more restricting parts 46 may be arranged side by side in the first direction X.

[0071] Furthermore, in the second embodiment, a pair of restricting portions 46 are arranged in contact with each other in the vertical direction Z, but this is not limited to this. Three or more restricting portions 46 may be arranged in contact with each other in the vertical direction Z.

[0072] Furthermore, in the embodiment shown above, the straight portion 461 of the restricting portion 46 extends in the second direction Y from the end of the opening S2, but is not limited to this. The straight portion 461 may extend so as it moves from the end of the opening S2 toward the second direction Y, it gradually moves toward the X2 side. This further suppresses the movement of the pair of restricting portions 46 toward the X1 side even when a force toward the X1 side is applied to the cable 22. [Explanation of Symbols]
