Description

[Technical field]

[0001] The present invention relates to a hoist running device having a hoist for running a fixture, a fixture equipped with such a hoist running device, and a method for removing the hoist main body from the fixture. [Background technology]

[0002] 2. Description of the Related Art There is known a fitting having recesses in both upper corners of a door panel for mounting support blocks for a hanging door hanger (see, for example, Patent Document 1). In such fittings, the support block of the hoist is attached to a recess in the door panel. The support block of the hoist is made small because it is set on a thin door panel. In other words, the support block of the hoist is located in a narrow area. For this reason, when maintaining the support block, it is necessary to use a special tool to remove the support block from the door panel, which can damage the support block and require meticulous, detailed work, which can reduce work efficiency.

[0004] The applicant has been working to improve the conventional hoist running device and has found that a problem occurs when handling the support block attached to the door panel. In other words, because the hoist running device places the hoist main body connected to the hoist section in a recess provided in the fixture, it was found that handling the hoist main body, specifically, the difficulty of removing the hoist main body from the fixture at a later date for maintenance work, poses a major issue. The present invention has been made in consideration of the above-mentioned circumstances, and aims to provide a hoist running device that allows the hoist main body to be removed from the main body positioning mounting part by applying a disconnecting tool from the outside. Another object of the present invention is to provide a fixture to which such a hoist running device is applied. Another object of the present invention is to provide a method for removing the hoist body when removing the hoist body from the body positioning attachment part. [Means for solving the problem]

[0005] The hoist running device according to the present invention is a hoist running device comprising: a hoist section having a hoist that runs a fitting along a horizontally positioned rail; a hoist main body section having a box-shaped body that is connected to the hoist section and fixed to the fitting; and a main body positioning attachment section that positions and attaches the hoist main body section to the fitting, wherein the main body positioning attachment section is positioned from the end face side of the fitting toward the back side and has a positioning protrusion that protrudes upward from the bottom of the end face side to determine the position of the hoist main body section, and the hoist main body section comprises a block-shaped recess that is located below the box-shaped body and covers the positioning protrusion from the end face side to the back side and engages with the positioning protrusion, a window frame section that is located above the end face side of the block-shaped recess and has a through hole that passes through from the end face side to the back side, an arm-shaped section that extends from the block-shaped recess to the back side, and the arm-shaped section that is located above the end face side of the block-shaped recess and has a through hole that passes through from the end face side to the back side, an arm-shaped section that extends from the block-shaped recess to the back side, and a positioning protrusion that is located below the box-shaped body and covers the positioning protrusion from the end face side to the back side and engages with the positioning protrusion. and a U-shaped leaf spring portion having one U-shaped end fixed to the arm-shaped portion and the other U-shaped end pressed against the box-shaped body to press the block-shaped recess against the positioning protrusion, the block-shaped recess being engaged with and fixed to the positioning protrusion when the hoist main body is fitted into the main body positioning attachment portion, and when the hoist main body is removed from the main body positioning attachment portion, a disconnecting jig inserted into the window frame portion from the outside pushes an upper frame of the window frame portion upward to release the engagement between the block-shaped recess and the positioning protrusion, and with upward pressure applied to the upper frame, the hoist main body is pulled out in accordance with the horizontal pulling out of the disconnecting jig. Therefore, in the hoist running device of the present invention, when the disconnecting jig is used to release the engagement between the hoist main body and the water tank stand cover (with upward pressure applied to the upper frame), and the disconnecting jig is pulled out horizontally, the hoist main body, on which the frictional force acts as is, is pulled out to the outside in accordance with the movement of the disconnecting jig.

[0006] In addition, the hoist running device according to one embodiment of the present invention is characterized in that the back side of the block-shaped recess is protruding and has an upwardly inclined portion extending toward the arm-shaped portion. In addition, in one embodiment of the hoist running device of the present invention, the upper frame is characterized in that it has an upper surface and a lower surface in a horizontal position along the rail when the hoist main body portion is set. In addition, in one embodiment of the hoist running device of the present invention, the connection release jig is characterized in that it is a flathead screwdriver-shaped body having a tip dimension that passes through the through hole, or a frame claw-holding body having an upward frame claw at the tip of the flathead screwdriver-shaped body that engages with the upper frame of the window frame portion.

[0007] In addition, the building fixture of the present invention is characterized in that it has a hoist running device attached to the end face side in the running direction, the hoist running device comprising a hoist section having a hoist that runs along a horizontally positioned rail, a hoist main section having a box-shaped body connected to the hoist section, and a main section positioning attachment section that positions and attaches the hoist main section, and the hoist running device is the hoist running device of the present invention. Therefore, the fitting according to the present invention is easy to maintain because the hoist body can be easily and efficiently removed.

[0008] Furthermore, the method for removing a hoist main body according to the present invention is a method for removing the hoist main body that has been fitted into a fixture, in a hoist running device comprising a hoist section having a hoist that runs a fixture along a horizontally positioned rail, a hoist main body having a box-shaped body connected to the hoist section and fixed to the fixture, and a body positioning and mounting section that positions and mounts the hoist main body, wherein the hoist running device is the hoist running device according to the present invention, the connection release jig is the flathead screwdriver-shaped body, and comprises the steps of: inserting the tip of the flathead screwdriver-shaped body into the window frame section; pushing up the tip of the flathead screwdriver-shaped body to push up the upper frame of the window frame section upward to release the engagement between the block-shaped recess and the positioning protrusion; and applying a horizontal external force to pull out the flathead screwdriver-shaped body while pushing up the upper frame with the tip of the flathead screwdriver-shaped body and releasing the engagement, thereby pulling out the hoist main body. Therefore, the method of removing the hoist main body according to the present invention involves using a flat-head screwdriver-shaped object to pull out the hoist main body, making it easy to remove the hoist main body by using a simple tool and a relatively simple process, and facilitating maintenance work on the hoist main body. Furthermore, the method for removing a hoist main body part according to the present invention is a method for removing the hoist main body part that has been fitted into a fixture, in a hoist running device that includes a hoist section having a hoist that runs a fixture along a horizontally positioned rail, a hoist main body part having a box-shaped body that is connected to the hoist section and fixed to the fixture, and a body positioning and mounting section that positions and mounts the hoist main body part, wherein the hoist running device is the hoist running device according to the present invention, the connection release jig is the frame claw-holding body, and the method comprises the steps of: inserting the tip of the frame claw-holding body into the window frame section, hooking the upward frame claws of the frame claw-holding body on the upper frame and pushing it upward to release the engagement between the block-shaped recess and the positioning protrusion, and applying a horizontal external pulling force that pulls out the frame claw-holding body while pushing up the upper frame, thereby pulling out the hoist main body part. Therefore, the method of removing the hoist main body according to the present invention uses a frame claw-holding body to pull out the hoist main body, making it easy to remove the hoist main body by using a simple jig and a relatively simple process, and facilitating maintenance work on the hoist main body. Effect of the Invention

[0009] The hoist running device of the present invention has a decoupling jig inserted into the window frame from the outside that disengages the block-shaped recess and the positioning protrusion, and while applying upward pressure to the upper frame, pulls out the hoist main body in conjunction with the horizontal withdrawal of the decoupling jig, thereby achieving the effect that the hoist main body can be easily removed by simple operation of the decoupling jig. In addition, since the fittings of the present invention apply the hoist running device of the present invention, the hoist main body can be easily and efficiently removed from the fittings, resulting in fittings that are easy to maintain.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 7). [Embodiment 1] Figs. 1 to 6 1 to 6, a description will be given of a hoist running device 1 and a fitting 50 according to a first embodiment of the present invention. In addition, a description will be given of a hoist main body removal method (steps) using a flathead screwdriver-shaped body T1 functioning as a connection release jig TJ. In addition, the second embodiment relates to a frame claw-holding body T2 that functions as a connection release jig TJ. When there is no need to distinguish between the flathead screwdriver-shaped body T1 and the frame claw-holding body T2, they may simply be referred to as connection release jig TJ. FIG. 1 is a separated perspective view showing a state in which a hoist unit 10 and a hoist main unit 20 are separated from a main unit positioning attachment unit 40 in a hoist running device 1 according to the first embodiment of the present invention, as viewed obliquely from above. Fig. 2 is a schematic partially cross-sectional perspective side view showing the state in which the hoist running device 1 shown in Fig. 1 is attached to a fitting 50, as seen from the side in a partially cross-sectional view. Note that in Fig. 2 and subsequent figures, the positioning protrusion 46, the block-shaped recess 24, the inclined portion 24s, the through hole 26, the window frame 28, the upper frame 29, the lower surface 29d, the upper surface 29h, and the like, which are the main parts of the present invention, are shown in cross section by hatching to aid understanding. Figure 3 is a schematic partially cross-sectional perspective side view showing the state in which a flathead screwdriver-shaped body T1 is inserted into the through hole 26 (see Figures 2 and 5) in order to separate the hoist main body 20 from the main body positioning mounting part 40 and pull it out to the outside in the hoist running device 1 shown in Figure 2. 4 is a schematic partially cross-sectional perspective side view showing the state in which the flathead screwdriver-shaped body T1 is moved upward to release the engagement of the block-shaped recess 24 with the positioning protrusion 46 in the hoist running device 1 shown in FIG. 5 is a schematic enlarged, partially sectional, see-through side view showing, in an enlarged scale, a state in which the positioning protrusion 46 and the block-shaped recess 24 are disengaged from each other in the hoist running device 1 shown in FIG. Figure 6 is a schematic side view, partially in section, showing the state in which the flathead screwdriver-shaped body T1 is pulled out horizontally in the hoist running device 1 shown in Figure 4 to separate the hoist main body 20 from the main body positioning mounting part 40 (fitting 50).

[0012] The cart running device 1 in this embodiment comprises a hoist unit 10 having a hoist 12 that runs the fitting 50 along a horizontally positioned rail 55, a hoist main body unit 20 having a box-shaped body 22 that is connected to the hoist unit 10 and fixed to the fitting 50, and a body positioning attachment unit 40 that positions and attaches the hoist main body unit 20 to the fitting 50. In the hoist running device 1, the main body positioning mounting portion 40 is positioned from the end face side of the building material 50 toward the rear side, and is provided with a positioning protrusion 46 that protrudes upward from the bottom of the end face side to determine the position of the hoist main body portion 20. The hoist body 20 is provided with a block-shaped recess 24 located below the box-shaped body 22, covering the positioning protrusion 46 from the end face side to the back side and engaging with it, a window frame 28 located above the end face side of the block-shaped recess 24 and having a through hole 26 passing from the end face side to the back side, an arm-shaped portion 30 extending from the block-shaped recess 24 to the back side, a rotating shaft 32 located at the back end of the arm-shaped portion 30 and rotating the window frame portion 28 like a pendulum, and a U-shaped leaf spring portion 34 having one end of a U-shape fixed to the arm-shaped portion 30 and the other end of the U-shape pressed against the box-shaped body 22 to press the block-shaped recess 24 against the positioning protrusion 46, the end face side of which is open. The fixed U-shaped end is connected to the lower side (arm-shaped portion 30). The other end of the U-shape is pressed against the box-shaped body 22 as a free end under the function of springiness. The main body positioning mounting part 40 is inserted and fixed in advance to the back and bottom sides of the space in which the hoist main body part 20 is to be mounted. The main body positioning mounting part 40 is fixed with the fitting rear part 42 positioned at the back side and the mounting bottom part 44 positioned at the bottom side. After the main body positioning mounting part 40 is positioned inside the fitting 50 (a space in which the main body positioning mounting part 40 is to be positioned as a mounting space for the hoist running device 1 is formed in advance), the hoist main body part 20 is inserted, positioned, and fixed.

[0013] In the hoist running device 1, when the hoist main body part 20 is fitted into the main body positioning mounting part 40, the block-shaped recess 24 engages with and is fixed in place (Figure 2), and when the hoist main body part 20 is removed from the main body positioning mounting part 40, the connection release jig TJ inserted into the window frame part 28 from the outside pushes the upper frame 29 of the window frame part 28 upward to release the engagement between the block-shaped recess 24 and the positioning protrusion 46, and with upward pressure applied to the upper frame 29, it is pulled out in conjunction with the horizontal pulling out of the hoist main body part connection release jig TJ (Figures 3 to 6). The positioning protrusion 46 of the main body positioning attachment part 40 and the block-shaped recess 24 of the hoist body part 20 are positioned relative to each other and engage with each other, so the main body positioning attachment part 40 can easily reliably position and fix the hoist body part 20 to the fitting 50. After positioning, the U-shaped leaf spring part 34 presses the arm part 30 against the main body positioning attachment part 40, making it easy to maintain stable fixation (Fig. 2).

[0014] In the hoist running device 1 of this embodiment, when the hoist main body part 20 is separated and removed from the fitting 50 (main body positioning mounting part 40), the hoist main body part 20 can be easily removed from the main body positioning mounting part 40 by a simple operation of inserting a disconnecting jig TJ from the outside into the window frame part 28 of the hoist main body part 20 and pushing up and pulling out the hoist main body part 20 (Figures 3 to 6). More specifically, when the disconnection jig TJ is used to release the engagement between the hoist main body 20 and the aquarium stand cover 40, and the disconnection jig TJ is pulled out horizontally, the hoist main body 20, on which the frictional force acts as is, is pulled out to the outside in accordance with the movement of the disconnection jig TJ. In other words, it is easy to simplify the work of removing the hoist body 20. This makes it easy to perform maintenance on the fitting 50.

[0015] The positioning protrusion 46 located on the mounting bottom 44 of the main body positioning mounting part 40 and the block-shaped recess 24 of the hoist main body 20 have matching meshing dimensions, so they can be positioned with high precision and fixed with high strength. The positioning protrusion 46 is preferably a protrusion with a rectangular cross section rising in a vertical direction intersecting with the running direction (horizontal direction) of the hoist running device 1. This configuration facilitates positioning with higher accuracy and fixing with higher strength. The hoist unit 10 includes a hoist 12 and a holding unit 14 that holds the hoist 12. The holding unit 14 is connected to a hoist body unit 20. The window frame portion 28 is located above the end face side of the block-shaped recess 24 that covers the positioning protrusion 46 and has a through hole 26 that passes from the end face side to the back side, so that it is easy to insert the connection release jig TJ from the outside. The inserted connection release jig TJ is pushed upward, so that it is easy to move the upper frame 29 upward to release the engagement between the positioning protrusion 46 and the block-shaped recess 24 (Figure 5). The hoist body portion 20, which has been released from the engagement with the block-shaped recess 24, can be easily removed as it is due to the frictional force of the connection release jig TJ moving horizontally.

[0016] In the described hoist running device 1, the back side of the block-shaped recess 24 is in the form of a protrusion, and has an inclined portion 24s that extends upward toward the arm portion 30 (see FIG. 5). The block-shaped recess 24 has an inclined portion 24s extending upward from the rear end toward the arm portion 30, and the U-shaped leaf spring portion 34 acts to cause the block-shaped recess 24 to move smoothly while preventing it from getting caught due to unevenness, making it easy to cover the positioning protrusion 46. In other words, when the hoist main body 20 before positioning is inserted into the mounting bottom 44, the inclined portion 24s of the block-shaped recess 24 cooperates with the U-shaped leaf spring portion 34 to rotate the arm-shaped portion 30 upward, and as a result, the block-shaped recess 24 moves smoothly to cover the positioning protrusion 46. In the hoist running device 1, the upper frame 29 has an upper surface 29h and a lower surface 29d in a horizontal position along the rail 55 when the hoist main body 20 is set (see FIG. 5). The hoist main body 20 is equipped with an upper frame 29 having an upper surface 29h and a lower surface 29d in the horizontal direction, which makes it easy to form and improves molding accuracy, and allows for easy and accurate positioning and operation when inserting the connection release jig TJ.

[0017] In the hoist running device 1 of this embodiment, the coupling release jig TJ is a flathead screwdriver-shaped body T1 (FIGS. 3 to 6) having a tip dimension that passes through the through-hole 26. The flathead screwdriver-shaped body T1 includes a flathead screwdriver itself or a similar member. The flathead screwdriver-shaped body T1 is composed of a gripping part (reference number omitted) that is held by a person and a metal part (reference number omitted) extending from the gripping part, and the metal part is a thin metal plate having a width and thickness according to the application. Since the connection release jig TJ is a flat-head screwdriver-shaped body T1, it is easy to ensure dimensional consistency and strength with the through hole 26 and the window frame portion 28, and it can be easily and accurately passed through the through hole 26 and pressed against the window frame portion 28 (Figures 4 and 5), and the hoist main body portion 20 can be efficiently pulled out from the main body positioning mounting portion 40.

[0018] The fitting 50 according to this embodiment will be described below. The fitting 50 according to this embodiment is equipped with a hoist running device 1, which includes a hoist section 10 having a hoist 12 that runs along a horizontal rail 55, a hoist main body section 20 having a box-shaped body 22 connected to the hoist section 10, and a main body positioning mounting section 40 that positions and mounts the hoist main body section 20, and is mounted on the end face side in the running direction. The fitting 50 is easy to maintain because the hoist body 20 can be easily and efficiently removed.

[0019] The method for removing the hoist body according to this embodiment will be described below. The method for removing the cart main body in this embodiment is a method for removing the cart main body 20 fitted into the fitting 50 in a cart running device 1 which comprises a cart section 10 having a cart 12 which runs the fitting 50 along a horizontally positioned rail 55, a cart main body 20 having a box-shaped body 22 which is connected to the cart section 10 and fixed to the fitting 50, and a body positioning and mounting section 40 which positions and mounts the cart main body 20, and the cart running device 1 is the cart running device 1 in this embodiment. The connection release jig TJ in this embodiment is a flathead screwdriver-shaped body T1, and the method for removing the hoist main body includes the steps of inserting the tip of the flathead screwdriver-shaped body T1 into the window frame portion 28 (Figure 3), pushing up the tip of the flathead screwdriver-shaped body T1 to push up the upper frame 29 of the window frame portion 28 upward to disengage the block-shaped recess 24 from the positioning protrusion 46 (Figures 4 and 5), and applying a horizontal external pulling force to pull out the flathead screwdriver-shaped body T1 while pushing up the upper frame 29 (lower surface 29d) with the tip of the flathead screwdriver-shaped body T1 and releasing the engagement, thereby pulling out the hoist main body 20 (Figure 6).

[0020] Fig. 3 shows the external force F1. The external force F1 (inward external force from the outside toward the hoist body 20 in the horizontal direction) is applied to the flathead screwdriver shaped body T1. As a result, the flathead screwdriver shaped body T1 is inserted into the through hole 26 (window frame portion 28. Note that reference numeral 26 is omitted in Fig. 3 for ease of viewing. See Figs. 2 and 5 for reference numeral 26). 4 and 5 show external force F2. External force F2 (an upward external force from the bottom to the top in the vertical direction) is applied to flathead screwdriver-shaped body T1. This causes lower surface 29d (window frame portion 28, upper frame 29) to move upward, and as a result, block-shaped recess 24 is released from engagement with positioning protrusion 46. 6 shows the external force F3. With the block-shaped recess 24 and the positioning protrusion 46 in the released state, the external force F3 (an external force directed from the inside to the outside in the horizontal direction) is applied to the flathead screwdriver-shaped body T1. The external force F3 is an outward force as shown in the figure, and is generated as the tip of the flathead screwdriver-shaped body T1 moves against the lower surface 29d that rubs against each other, and acts as a pulling-out external force in the horizontal direction, pulling the hoist main body 20 outward. In addition, in Figs. 3 to 6, the external forces F1, F2, and F3 are shown typically on the gripping portion of the flathead screwdriver-shaped body T1, but in reality, the flathead screwdriver-shaped body T1 is operated so that the same external forces act on the tip thereof. The hoist running device 1 in this embodiment inserts a flathead screwdriver-shaped body T1 into the window frame portion 28, pushes up the upper frame 29 of the window frame portion 28 to disengage the block-shaped recess 24 from the positioning protrusion 46, and while maintaining the vertical position of the upper frame 29, applies a horizontal external pulling force to the flathead screwdriver-shaped body T1 to pull out the flathead screwdriver-shaped body T1. As a result, in the hoist body removal method according to the present embodiment, the flathead screwdriver-shaped body T1 is used to pull out the hoist body 20, so that the hoist body 20 can be easily removed by using a simple tool and a relatively simple process, and the maintenance work on the hoist body 20 can be easily performed. Since the flathead screwdriver-shaped body T1 is used, the hoist body 20 can be easily removed without being damaged.

[0021] [Embodiment 2] Fig. 7, Fig. 1 to Fig. 6 7 and 1 to 6, a description will be given of a hoist running device 1 and a fitting 50 according to a second embodiment of the present invention. In addition, a description will be given of a hoist main body removal method (steps) using a frame claw-holding body T2 that functions as a connection release jig TJ. In the hoist running device 1 and the fitting 50 according to this embodiment, matters other than the frame claw-holding body T2 are the same as those in the first embodiment, so the same reference numerals are used and the description is omitted. In other words, the basic configuration is the same as in Figs. 1 to 6, so the same parts are used with the same reference numerals and the description is omitted as appropriate. Figure 7 is a partially cross-sectional, perspective, schematic enlarged side view showing an enlarged state in which the positioning protrusion 46 and the block-shaped recess 24 are disengaged by the frame claw-holding body T2, corresponding to the enlarged view of the flathead screwdriver-shaped body T1 shown in Figure 5.

[0022] In the hoist running device 1 according to this embodiment, the connection release jig TJ is a frame claw holder body T2 having an upward frame claw T2c at the tip of a flathead screwdriver body T1 that engages with the upper frame 29 of the window frame portion 28. The connection release jig TJ is a frame claw-holding body T2 having an upward frame claw T2c at the tip of the flathead screwdriver-shaped body T1 that hooks onto the upper frame 29 of the window frame portion 28, so that it is easy and accurate to pass through the through hole 26, and for the flathead screwdriver-shaped body T1 to be pressed against the window frame portion 28, and for the frame claw-holding body T2 to be hooked onto the window frame portion 28, and the hoist main body 20 can be easily and efficiently pulled out from the main body positioning mounting portion 40. The frame claw-holding body T2 means that the tip of the flathead screwdriver-shaped body T1 has a frame claw T2c that hooks onto the upper frame 29 of the window frame portion 28. The dimensions of the frame claw T2c in the frame claw-holding body T2 are determined taking into consideration the consistency with the dimensions of the through hole 26 and the window frame portion 28 and ensuring strength.

[0023] The method for removing the hoist body according to this embodiment will be described below. The method for removing the hoist main body part in this embodiment is a method for removing the hoist main body part 20 fitted into the fitting 50 in a hoist running device 1 which comprises a hoist section 10 having a hoist 12 which runs the fitting 50 along a horizontally positioned rail 55, a hoist main body part 20 having a box-shaped body 22 which is connected to the hoist section 10 and fixed to the fitting 50, and a body positioning and mounting part 40 which positions and mounts the hoist main body part 20, and the hoist running device 1 is the hoist running device 1 in embodiment 1. The connection release jig TJ in this embodiment is a frame claw-holding body T2, and the method for removing the hoist main body includes the steps of inserting the tip of the frame claw-holding body T2 into the window frame portion 28 (similar to Figure 3), hooking the upward frame claw T2c of the frame claw-holding body T2 on the upper frame 29 and pushing it upward to disengage the block-shaped recess 24 from the positioning protrusion 46 (Figure 7), and applying a horizontal external pull-out force to pull out the frame claw-holding body T2 while pushing up the upper frame 29, thereby pulling out the hoist main body 20 (similar to Figure 6). A frame claw-holding body T2 is inserted in place of the flathead screwdriver-shaped body T1 in FIG. 3, and an external force F1 (see embodiment 1) is applied to the frame claw-holding body T2 in the same manner as the flathead screwdriver-shaped body T1. An external force F2 (FIG. 7) (see embodiment 1) is applied to the frame claw-retaining body T2, which replaces the flathead screwdriver-shaped body T1 in FIG. 4 and FIG. 5. This causes the lower surface 29d (window frame portion 28, upper frame 29) to move upward, and as a result, the block-shaped recess 24 is released from the engagement with the positioning protrusion 46. After Fig. 7, an external force F3 (see embodiment 1) is applied to the frame claw-holding body T2, which replaces the flathead screwdriver-shaped body T1 in Fig. 6, while maintaining the open state between the block-shaped recess 24 and the positioning protrusion 46. The external force F3 is an outward force as shown in the figure, and acts as a pulling-out external force in the horizontal direction, so that the hoist main body 20 is pulled out to the outside.

[0024] The hoist running device 1 in this embodiment inserts the frame claw-holding shaped body T2 into the window frame portion 28, hooks the frame claw T2c on the upper frame 29 and pushes the upper frame 29 upward to release the engagement between the block-shaped recess 24 and the positioning protrusion 46, and while the upward frame claw T2c is hooked on the upper frame 29 to maintain its vertical position, a horizontal external pulling force is applied to the frame claw-holding shaped body T2 to pull out the frame claw-holding shaped body T2. As a result, the hoist main body removal method according to this embodiment uses the frame claw-holding shaped body T2 to pull out the hoist main body 20 via the frame claws T2c and the window frame part 28 (upper frame 29), so that it is easy to remove the hoist main body 20 by using a simple tool and a relatively simple process, and it is easy to perform maintenance work on the hoist main body 20. Because the frame claw-holding shaped body T2 is used, the hoist main body 20 can be easily removed without being damaged. [Industrial Applicability]

[0025] The hoist running device, fittings, and method for removing the hoist main body of the present invention are highly usable because the hoist main body of the hoist running device can be easily removed from the fittings and is effective for maintenance. [Explanation of symbols]
