Description

[Technical Field]

[0001] FIELD OF THE INVENTION An embodiment of the present invention relates to a wall hanging installation assist device and a wall hanging installation method. [Background technology]

[0002] For example, at construction sites, factories, etc., wall-mounted panels such as distribution boards and control panels are installed manually by workers. Some wall-mounted panels weigh over 90 kg and are installed at positions as high as 120 cm to 130 cm from the ground, so the task of manually lifting the wall-mounted panel and maintaining its position while installing it on the wall poses the following problems:

[0003] In other words, manual installation requires multiple workers (for example, four people) working closely together. If multiple workers do not work in unison, there is a risk of workers falling, the wall-mounting panel dropping, or coming into contact with existing objects, which could lead to injury or accidents.

DETAILED DESCRIPTION OF THE INVENTION

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the wall hanging attachment assisting device and the wall hanging attachment method of the present invention will be described with reference to the drawings.

[0009] (Configuration and operation of the embodiment) FIG. 1 is a left side view showing the overall external configuration of a wall-hanging board mounting auxiliary device 1 according to an embodiment of the wall-hanging item mounting auxiliary device and the wall-hanging item mounting method.

[0010] FIG. 2 is a left side view showing the overall external configuration of a work site in which the wall-mounted panel SB is attached to a wall W using the wall-mounted panel attachment auxiliary device 1 according to the embodiment.

[0011] In Figures 1 and 2, the surface of the wall-mounted panel mounting auxiliary device 1 of the embodiment is defined as the left side, the surface seen from the left as the front, the surface seen from the right as the back, and the surface seen from the back as the right side.

[0012] The wall-mounted panel mounting auxiliary device 1 includes a wall-mounted panel support device 10, a stepladder 20, and a base slider 30 (slider member).

[0013] The wall-mounted panel support device 10 has the function of being detachably attached to any pair of upper and lower treads 22a, 22b on the stepladder 20 (tread attachment mechanism 17F), the function of supporting the back surface of the wall-mounted panel SB, where the attachment hole in is located, facing the front of the wall-mounted panel attachment auxiliary device 1 (base frame 11, slide frame 12, panel support frame 14 (object support member)), the function of adjusting and changing the height of the supported wall-mounted panel SB in the vertical direction (arrows X, x1, x2) (panel jack mechanism 16J), and the function of adjusting and changing the position of the supported wall-mounted panel SB in the front-to-back direction (arrow y: direction horizontally away from the stepladder 20) (slide rail section 12b: left slide rail 13L, right slide rail 13R (see Figures 4 and 6)).

[0014] FIG. 3 is a left side view showing the configuration of the wall-mounted panel support device 10 provided in the wall-mounted panel mounting auxiliary device 1. As shown in FIG.

[0015] FIG. 4 is a front view showing the configuration of the wall-mounted panel support device 10 provided in the wall-mounted panel mounting auxiliary device 1. As shown in FIG.

[0016] FIG. 5 is a rear view showing the configuration of the wall-mounted panel support device 10 provided in the wall-mounted panel mounting auxiliary device 1. As shown in FIG.

[0017] FIG. 6 is a top view showing the configuration of the wall-mounted panel support device 10 provided in the wall-mounted panel mounting auxiliary device 1. As shown in FIG.

[0018] As shown in Fig. 3, the wall-mounted panel support device 10 comprises a base frame 11, a slide frame 12, and a panel support frame 14, all of which form an inverted L shape when viewed from the left side. For example, as shown in Fig. 5, the base frame 11, slide frame 12, and panel support frame 14 all have a width that is at least two-thirds the left-right width of the wall-mounted panel SB to be attached, and are assembled in the order of the base frame 11, slide frame 12, and panel support frame 14, which are attached to a stepladder 20, so as to support the L-shaped surface formed by the front and bottom surfaces of the wall-mounted panel SB.

[0019] The base frame 11 includes a stepladder mounting base frame portion 11a that is arranged parallel to the support posts 21 of the stepladder 20 when attached to a pair of upper and lower rungs 22a, 22b of the stepladder 20, and a horizontal base frame portion 11b that extends horizontally forward (towards the front) from the lower end portion 11a2 of the stepladder mounting base frame portion 11a.

[0020] The slide frame 12 includes an upper and lower slide portion 12a that slides up and down parallel to the support 21 of the stepladder 20, as shown by arrows x1 and x2, while overlapping along the front of the stepladder mounting base frame portion 11a, and a slide rail portion 12b that extends horizontally (i.e., parallel to the horizontal base frame portion 11b) forward (towards the front) from the lower end portion 12a2 of the upper and lower slide portion 12a.

[0021] The slide frame 12 is combined with the base frame 11 by engaging multiple slide pins 12s protruding from the back of the upper and lower slide sections 12a with slide grooves 11aL, 11aR (see Figures 3 and 4) provided in the vertical direction on the left and right sides of the front of the ladder mounting base frame section 11a, and is configured to be slidable up and down relative to the base frame 11 as shown by arrows x1 and x2.

[0022] In addition, as shown in Figures 4 and 6, the slide rail portion 12b of the slide frame 12 is composed of a left slide rail 13L and a right slide rail 13R that are provided at the lower end portion 12a2 of the upper and lower slide portion 12a, respectively, facing forward (towards the front).

[0023] The left slide rail 13L and the right slide rail 13R are each based on fixed rail sections (outer members) 13Lf, 13Rf, which have their base ends fixed to the lower end 12a2 of the upper and lower slide sections 12a, and are configured to be slidable toward the front of the wall-mounted panel support device 10, as shown by arrow y, by combining them with movable rail sections (inner members) 13Lm, 13Rm, which are slidably mounted inside the fixed rail sections 13Lf, 13Rf via ball bearings not shown.

[0024] The panel support frame 14 includes a front support frame portion 14a and a bottom support frame portion 14b that directly support the L-shaped surface formed by the front and bottom surfaces of the wall-mounted panel SB. The bottom support frame portion 14b is combined with the slide frame 12 with the left slide rail 13L and right slide rail 13R of the slide rail portion 12b inserted into a hollow portion that opens on the back side of the lower end of the front support frame portion 14a.

[0025] The left and right sliding rails 13L and 13R are inserted into the hollow portions of the bottom support frame 14b, and their movable rail portions 13Lm and 13Rm are fixed to the underside of the top plate of the bottom support frame 14b. The bottom support frame 14b slides retractably toward the front of the wall-mounted panel support device 10 as indicated by arrow y, accompanied by the sliding of the movable rail portions 13Lm and 13Rm of the left and right sliding rails 13L and 13R.

[0026] Therefore, the board support frame 14 that directly supports the wall-mounted board SB is combined with the slide frame 12 that slides up and down so as to be slidable toward the front of the wall-mounted board support device 10.

[0027] Between the left and right ends of the front support frame portion 14a of the board support frame 14, a belt 15 is provided to fasten and secure the wall-mounted board SB placed and supported on the bottom support frame portion 14b so that it does not fall.

[0028] <Panel jack mechanism 16J> As shown in Figures 3 and 5, the panel jack mechanism 16J includes a winch base 16B extending rearward from the upper surface of the lower end 11a2 of the base frame 11, a small manual winch 16 mounted on the winch base 16B, a pulley 16P hanging down from the underside of the upper end 11a1 of the base frame 11 near the center of the left and right sides and to which a winch wire 16W pulled out from the manual winch 16 is hung, and a wire connecting portion 16C erected on the upper surface of the lower end 12a2 of the slide frame 12 near the center of the left and right sides and to which the tip of the winch wire 16W pulled out from the manual winch 16 via the pulley 16P is connected.

[0029] When the handle 16H of the manual winch 16 is rotated to one side or the other as shown by arrow R, the winch wire 16W is wound onto or unwound from the manual winch 16 as shown by arrow X, causing the slide frame 12, which is connected to the wire connecting portion 16C via the pulley 16P, to rise as shown by arrow x1 or fall as shown by arrow x2.

[0030] Therefore, the panel jack mechanism 16J can slide the slide frame 12 up and down relative to the base frame 11 as shown by arrows x1 and x2, thereby adjusting the vertical height of the wall-mounted panel SB supported by the panel support frame 14.

[0031] In the panel jack mechanism 16J, the power source for sliding the slide frame 12 up and down relative to the base frame 11 is not limited to the small manual winch 16, but may be, for example, a small manual jack.

[0032] <Step bar attachment mechanism 17F> As shown in Figures 3, 5 and 6, the tread mounting mechanism 17F is provided at a total of four locations: two locations on the left and right sides of the back side of the upper end portion 11a1 of the base frame 11, and two locations on the left and right sides of the back side of the lower end portion 11a2 of the base frame 11.

[0033] In the four tread bar attachment mechanisms 17F at the top, bottom, left, and right, the vertical spacing is designed to correspond to the spacing between a pair of upper and lower tread bars 22a, 22b on the stepladder 20, and the horizontal spacing is designed to correspond to the length (horizontal width) of the tread bars 22a, 22b on the stepladder 20. Each of the four tread bar attachment mechanisms 17F may be provided so that the horizontal spacing and the vertical spacing can be adjusted.

[0034] The tread bar mounting mechanism 17F includes a hook-shaped tread bar hook portion 17C that extends horizontally rearward from the back of the base frame 11 a length that exceeds at least the front-to-back width of the tread bar 22 and bends downward at a right angle a length that exceeds at least the thickness of the tread bar 22; a tread bar clamping portion 17M that faces the inner surface of the tip of the tread bar hook portion 17C and is slidable in a direction to narrow or widen the gap between them; and a butterfly bolt 17B that is screwed from near the lower end of the tip surface of the tread bar hook portion 17C, through the tip portion and the tread bar clamping portion 17M.

[0035] The tread clamping portion 17M is combined with the tread hooking portion 17C by engaging a slide pin 17s protruding from its upper end surface with a slide groove 17L provided in the front-to-rear direction on the underside of the horizontal part of the tread hooking portion 17C, and is configured to be slidable in the direction of narrowing or widening the opposing distance between the inner surface of the tip of the tread hooking portion 17C and the inner surface of the tip of the tread hooking portion 17C in accordance with the rotation operation of the butterfly bolt 17B.

[0036] Therefore, the step bar mounting mechanisms 17F provided at four locations on the top and bottom of the back side of the wall-mounted panel support device 10 can clamp any pair of upper and lower step bars 22a, 22b provided on the stepladder 20 by removing, attaching, and rotating each of the butterfly bolts 17B, thereby allowing the wall-mounted panel support device 10 to be attached and detached freely to the stepladder 20.

[0037] FIG. 7 is an enlarged perspective view showing the relationship between the stepladder 20 and the base slider 30 provided in the wall-mounted panel mounting auxiliary device 1. As shown in FIG.

[0038] The base slider 30 has a structure in which the contact points with the floor surface F on its underside are reduced to reduce frictional resistance and make it easier to slide, and is designed to be easily slidable on the floor surface F by hand even when carrying a heavy object, for example, 100 kg or more (for example, a "Slider Board" by Daisan Co., Ltd. may be used).

[0039] As shown in Figures 1, 2 and 7, the wall-mounted panel installation auxiliary device 1 is provided with two posts 21 (two sets at the front and back) that support multiple rungs 22 on the left and right at the front and back of the top plate of the stepladder 20, and two flat rectangular base sliders 30 on which the lower ends of the two posts 21 are placed for each set.

[0040] A rectangular, cylindrical support insertion portion 31, for example, is provided on the upper surface of each base slider 30, corresponding to the distance between the lower ends of a pair of support posts 21 in the stepladder 20. The lower ends of the support posts 21 of the stepladder 20 are inserted into the support insertion portion 31 and attached to the base slider 30, whereby the stepladder 20 is set upright via the base slider 30 on the floor surface F.

[0041] Therefore, even when the wall-hanging board SB, which is a heavy object, is placed and supported on the wall-hanging board support device 10 attached to the stepladder 20, the base slider 30 can be easily slid and moved on the floor surface F, and the wall-hanging board SB can be moved to the side of the wall W, where it is to be attached, with a small workload.

[0042] FIG. 8 is an enlarged side view showing the relationship between the mounting hole in of the wall-mounted board SB supported on the board support frame 14 of the wall-mounted board support device 10 and the anchor bolt ab attached to the wall W.

[0043] A chain-attached hook 18 using a carabiner or the like connected by a chain 18c may be provided at the tip of the horizontal base frame portion 11a of the base frame 11 of the wall-mounted board support device 10.

[0044] The wall-mounted board SB is attached and fixed to the wall W by screwing and tightening a nut N onto the anchor bolt ab of the wall W that is inserted into the mounting hole in. At this time, the nut N is temporarily screwed onto the tip of the anchor bolt ab that is inserted into the mounting hole in, and the chain-attached hook 18 is temporarily hung on the anchor bolt ab. This prevents the wall-mounted board support device 10 and the stepladder 20 carrying the wall-mounted board SB from falling over if they lose balance due to some external factor.

[0045] The nuts N can be tightened onto the anchor bolts ab inserted into the mounting holes in of the wall-mounted panel SB from the front of the wall-mounted panel SB placed on the panel support frame 14 with the door of the wall-mounted panel SB removed.

[0046] (Wall-mounted panel SB installation procedure) (1) As shown in Figure 7, insert and attach the support posts 21 of the stepladder 20 into the support post insertion portions 31 of two base sliders 30 (slider components) placed on the floor surface F, and place the stepladder 20 in an upright position relative to the floor surface F via the base sliders 30, as shown in Figure 1.

[0047] (2) As shown in Figure 2, worker H (user) takes into consideration the approximate height at which the wall-mounted panel SB will be attached to the wall W, and operates its step attachment mechanism 17F to attach the wall-mounted panel support device 10 to any pair of upper and lower step bars 22a, 22b of the stepladder 20.

[0048] (3) Worker H places the wall-mounted panel SB on the panel support frame 14 (object support member) of the wall-mounted panel support device 10 with the back side with the mounting holes in facing the front of the wall-mounted panel support device 10, and tightens and secures it with the belt 15.

[0049] (4) Worker H slides the stepladder 20 together with the base slider 30 along the floor surface F until it approaches the wall W, and places the back of the wall-mounted board SB, which has the mounting holes in it, facing the mounting surface of the wall W closely.

[0050] (5) Worker H operates the panel jack mechanism 16J of the wall-mounted panel support device 10, and slides the slide frame 12 and panel support frame 14 up and down as shown by arrows x1 and x2 to fine-tune the height of the wall-mounted panel SB, aligning the position of the mounting hole in of the wall-mounted panel SB with the position of the anchor bolt ab attached to the wall W.

[0051] (6) Worker H slides the wall-mounted panel SB together with the panel support frame 14 forward (in the direction horizontally away from the stepladder 20) as shown by arrow y until its back surface is in close contact with the wall W, and temporarily fastens it by screwing nut N onto the tip of anchor bolt ab inserted into mounting hole in as shown in Figure 8. Then, worker H temporarily hangs chain-attached hook 18 connected to the tip of horizontal base frame portion 11a on anchor bolt ab to prevent the wall-mounted panel support device 10 and stepladder 20 from accidentally tipping over.

[0052] (7) Worker H removes the chain hook 18 from the anchor bolt ab and fully tightens the nut N threaded onto the anchor bolt ab to secure the wall-mounted board SB to the wall W. He then removes the belt 15 fastened to the wall-mounted board SB to release the wall-mounted board SB from its connection to the wall-mounted board support device 10, completing the installation of the wall-mounted board SB on the wall W.

[0053] (Summary of the embodiment) According to the embodiment of the wall-mounted panel mounting auxiliary device 1, the back surface of the wall-mounted panel SB with the mounting holes in facing forward, and the wall-mounted panel support device 10 including a panel support frame 14 (object support member) for placing and supporting (fixing with a belt 15) the wall-mounted panel SB, is attached to any pair of upper and lower treads 22a, 22b on the stepladder 20 by a step mounting mechanism 17F provided on the back side of the wall-mounted panel support device 10, and the wall-mounted panel SB is held in a state where the approximate height required for mounting on the wall W is secured by the stepladder 20.

[0054] The stepladder 20 is slid on the floor surface F using the base slider 30 (slider member) until the back of the wall-mounted board SB supported by the wall-mounted board support device 10 is moved to a position where it faces closely the anchor bolt ab attached to the wall W, and the board support frame 14 is slid up and down using the board jack mechanism 16J, and the height of the wall-mounted board SB is fine-tuned so that its mounting hole in matches the height of the anchor bolt ab on the wall W.

[0055] Then, the panel support frame 14 carrying and supporting the wall-mounted panel SB is slid forward (in the direction horizontally away from the stepladder 20) from the wall-mounted panel support device 10 by the slide rails 13L, 13R of the slide frame 12 until the anchor bolts ab of the wall W are inserted into the mounting holes in of the wall-mounted panel SB and the back surface of the wall-mounted panel SB is in close contact with the wall W. The anchor bolts ab inserted into the mounting holes in are tightened with nuts N to secure the wall-mounted panel SB to the wall W.

[0056] In this way, the wall-mounting board SB, which is a heavy object, can be easily and safely mounted at any desired mounting location on the wall W with little work load in any of the operations of lifting, moving and aligning it.

[0057] Therefore, according to the wall-mount panel mounting auxiliary device 1 of the embodiment, the number of people required for the work can be reduced, and the work of mounting the wall-mount panel SB can be performed easily and safely.

[0058] In the above-described embodiment, a wall-mounted panel mounting auxiliary device 1 was described that easily and safely mounts a heavy wall-mounted panel SB to a wall W. However, the heavy object to be mounted on the wall W is not limited to a wall-mounted panel SB such as a distribution board or control panel, and may be other objects.

[0059] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
