Description

The present invention relates to a folding work scaffold that can be folded by folding the scaffolding board in half.

A folding work scaffold used mainly for interior construction and small-scale building construction is known in which the scaffold board is divided into two parts down the middle, and the board is folded in half and the divided halves are brought together toward the center to make it foldable (for example, Patent Document 1).

The folding work scaffold disclosed in Patent Document 1 comprises a scaffold board that is divided into two at approximately the center in the longitudinal direction (left-right direction), a pair of legs that are provided on the underside of the scaffold board and support the scaffold board from below, and pantograph-shaped diagonal braces that connect the legs together. After the scaffold board and the legs are released from their fixed position, the diagonal braces are contracted to bring the legs closer together, and the scaffold board is folded downward (mountain fold) towards the outside of the legs. Conversely, when unfolding, the downward-folded scaffold board is returned to the horizontal position, the diagonal braces are expanded to move the legs away from each other, and the scaffold board and the legs are fixed together by a fixing pin or the like.

JP 2011-52474 A

This type of folding work scaffold is provided with swivel wheels at the lower ends of the legs to facilitate ease of installation and removal. However, in the folding work scaffold of Patent Document 1, the legs are not connected to the scaffold board. Therefore, when the legs are released from their fixed state with the scaffold board, the movement of the swivel wheels affects the legs when moving the legs closer to or farther away from each other as described above, and they do not move stably in the direction of approaching or moving away from each other, making it difficult to unfold or fold smoothly.

The present invention was made in consideration of the above problems, and aims to provide a folding work scaffold that can be folded by folding the scaffolding boards in half, and can be smoothly unfolded and folded.

To solve the above problems, the folding work scaffold of the present invention employs the following technical measures.

A folding work scaffold according to one aspect of the present invention comprises a scaffold board divided into left and right halves, a pair of legs arranged opposite each other on the underside of the scaffold board and supporting each of the divided halves of the scaffold board from below, a support frame provided in a central position between the left and right on the underside of the scaffold board and supporting the divided halves rotatably between a horizontal position and a downward folded position, and a connecting frame connecting the legs to the support frame so that they can be moved toward and away from each other , wherein the divided halves extend in the left-right direction along the underside of the divided halves and have guide portions that guide the legs along the underside, the legs are slidably connected to the guide portions , and are configured so that they can be moved to a position where they are brought together against the support frame while the divided halves are held in the horizontal position .

The leg body may have a first link portion and a second link portion arranged side by side on the upper part of the leg body and slidably engaged with the guide portion, and the first link portion may be configured so that, when the leg body is moved to a position where it is brought close to the support frame, the first link portion is released from its engaged state with the guide portion, allowing the split half body to rotate to the downward folded position .

A folding work scaffold according to another aspect of the present invention is a folding work scaffold comprising: a scaffold board divided into left and right parts; a pair of legs arranged opposite each other on the underside of the scaffold board and supporting each divided half of the scaffold board from below; a support frame provided in a central position between the left and right on the underside of the scaffold board and supporting the divided half rotatably between a horizontal position and a downward folded position; and a connecting frame connecting the legs to the support frame so that they can approach and move away from each other, The legs are slidably connected, and the split halves are provided with a guide portion that guides the legs to slide in the left-right direction, and the legs are provided with at least two piece portions arranged side by side on the left and right and slidably engaged with the guide portion, and when the legs are in a position close to the support frame, the engagement state of a first piece portion with the guide portion is released, and a second piece portion is engaged with the guide portion and is arranged coaxially with a pivot portion that pivotally connects the split halves and the support frame to each other.

The folding work scaffold may be provided with a locking mechanism on the divided half or the support frame, which is capable of fixing and holding the divided half in the horizontal position.

The folding work scaffold according to an embodiment of the present invention will be described below with reference to the drawings. Note that the embodiment described below is an example of the present invention, and the configuration of the present invention is not limited to this specific example.

As shown in Figures 1 to 6, the folding work scaffold 1 of this embodiment comprises a scaffold board 2, legs 3, a support frame 4, and a connecting frame 5.

The scaffold board 2 is a plate body having a generally rectangular shape when viewed from above, and is divided into two at the center between the left and right. In this embodiment, the longitudinal direction of the scaffold board 2 is the left-right direction, the lateral direction of the scaffold board 2 is the front-rear direction, and the thickness direction of the scaffold board 2 is the up-down direction of the folding work scaffold 1. In addition, in this embodiment, the configuration in the unfolded state will be described as the basis, except when describing the folded state.

The legs 3 are arranged in a pair on the left and right opposite sides on the underside of the scaffold board 2, and support the left and right split halves (hereinafter referred to as "scaffold board halves") 2P of the scaffold board 2 from below. The support frame 4 is provided in a central position between the left and right sides on the underside of the scaffold board 2, and supports the scaffold board half 2P so that it can rotate between a horizontal position and a downward bent position arranged along the legs 3. The connecting frame 5 is provided between the left and right legs 3 and the support frame 4, and connects the legs 3 to the support frame 4 so that they can move toward and away from each other.

The scaffolding board half body 2P includes an outer frame 6, a middle frame 7, a step 8, and a rail portion 9. The outer frame 6 is formed by connecting long frame materials having a substantially rectangular cross section in a substantially square shape. The middle frame 7 is formed by connecting long frame materials having a substantially rectangular cross section so as to cross front, rear, left and right. The step 8 is provided over substantially the entire inner surface of the outer frame 6 and is supported from below by the middle frame 7. In the present embodiment, the step 8 is formed of a lattice-shaped net body, but as long as it has sufficient strength such as load resistance and impact resistance, the step 8 may be formed of a flat plate or a corrugated plate. In addition, the step 8 may be formed by arranging a plurality of narrow plate materials, tube materials, wire materials, etc.

A pad 6S is provided on each of the opposing surfaces of the two scaffolding board halves 2P in the outer frame 6. The pads 6S come into contact with each other when the two scaffolding board halves 2P are rotated to a horizontal position. This keeps the scaffolding board halves 2P positioned in a horizontal position.

The rails 9 are provided at the front and rear of the underside of the scaffolding board half 2P, extending in parallel in the left-right direction along the underside. The rails 9 are formed from a long frame material with a roughly U-shaped cross section, and have a groove-shaped opening (hereinafter referred to as the "groove") 9S extending in the left-right direction on the surface (inner surface) at the center of the front and rear of the scaffolding board 2. Stoppers 9E are provided at the left and right ends of the grooves 9S to lock the legs 3 in a predetermined deployed position (see Figure 9).

The outer surface of the rail section 9 (the surface located on the front and rear outside of the scaffolding board 2) is provided with a first plunger 11 as a locking mechanism that can fix and hold the scaffolding board half 2P in a horizontal position relative to the support frame 4, and a second plunger 12 that can fix and hold the leg 3 in an expanded position away from the support frame 4 (see Figures 7 and 8).

The lower edge 9B of the rail section 9 is formed in a range from the outer end of the scaffolding board half 2P (the outer left and right sides of the scaffolding board 2) to the front or rear facing position of the hinge section 28 connecting the scaffolding board half 2P and the support frame 4. In addition, a notch 9H of a predetermined width that opens downward is provided at the end of the inner side of the scaffolding board half 2P (the center left and right side of the scaffolding board 2) on the underside of the rail section 9. In other words, the underside of the end of the rail section 9 on the center left and right side of the scaffolding board 2 opens downward (see Figure 7).

The leg body 3 includes a support frame 13, a sliding support 14, a middle cross-section 15, a lower cross-section 16, and a swivel wheel 17. The support frame 13 is formed of a long frame material with a roughly rectangular cross-section, and a pair of them are provided in parallel at the front and rear of the leg body 3. The sliding support 14 is formed of a long frame material with a roughly rectangular cross-section, and is inserted and held in the inner space of the support frame 13. The middle cross-section 15 is formed of a long frame material with a roughly rectangular cross-section, and is horizontally supported between the support frames 13. The lower cross-section 16 is horizontally supported between the lower ends of the sliding support 14. The swivel wheel 17 is connected to the lower end of each sliding support 14.

A third plunger 18 capable of fixing and holding the sliding support 14 at a predetermined height is provided at a height position near the lower end on the outer periphery of the support frame 13. Meanwhile, on the outer surface of the sliding support 14, multiple engagement holes (not shown) capable of engaging and holding the third plunger 18 are provided vertically at predetermined intervals. Therefore, the vertical length of the leg 3 can be adjusted by sliding the sliding support 14 up and down in the inner space of the support frame 13 and fixing it at a predetermined position with the third plunger 18.

In addition, at a height position near the lower end on the outer periphery of the support frame 13, a hook hole 3H capable of hooking and holding the second plunger 12 is provided, and by hooking the tip of the second plunger 12 into the hook hole 3H, the top board half 2P can be fixed and held in a downward bent position arranged along the leg 3. In this way, the second plunger 12 has both the function of fixing and holding the leg 3 to the scaffold board half 2P in the deployed position, and the function of fixing and holding the scaffold board half 2P to the leg 3 in the downward bent position.

A fourth plunger 19 is provided at approximately the center between the top and bottom of the outer periphery of the support frame 13, which can fix and hold the leg 3 in a position where it is brought close to the support frame 4. Meanwhile, the support frame 4 is provided with an engagement hole 4H in which the fourth plunger 19 can be engaged and held, and by engaging the tip of the fourth plunger 19 with the engagement hole 4H, the leg 3 can be fixed and held in a state where it is brought close to the support frame 4.

A runner 20 is provided at the upper end of the support frame 13. As shown in Figures 8 to 12, the runner 20 comprises two pieces 21, 22 and a support plate 23. The support plate 23 is a plate formed in a generally trapezoidal shape with a long upper base and a short lower base, and is fixed in a superimposed state to the outer circumferential surface of the support frame 13 so that a generally triangular tip 23A with an inclined side protrudes toward the outside of the support frame 13 (the left and right outside of the scaffolding board 2).

The link parts 21 and 22 are circular rotors that are pivotally connected side by side to the left and right near the top of the support plate 23. The legs 3 are connected and held slidably in the left-right direction relative to the scaffolding board half body 2P by engaging the link parts 21 and 22 from above with the lower edge 9B of the rail part 9.

Of the link parts 21, 22, the first link part 21 is disposed in a central position between the left and right sides of the support frame 13, and the other link part 22 is disposed at the tip 23A of the support plate 23 that protrudes outward from the support frame 13. Therefore, when the leg 3 is slid along the rail part 9 to the end on the outside of the scaffolding board half 2P (the outside of the left and right sides of the scaffolding board 2), the second link part 22 abuts against the stopper 9E of the rail part 9. This causes the leg 3 to be locked in the deployed position relative to the rail part 9 (see Figure 11).

On the other hand, when the leg 3 is slid along the rail portion 9 to the end of the inside of the scaffolding board half 2 (the left and right center side of the scaffolding board 2), the first piece 21 is disposed at a position above the notch 9H in the rail portion 9, and the engagement with the rail portion 9 is released. At this time, the second piece 22 is disposed at a position facing the front or rear of the hinge portion 28, specifically, at a position where the axis passing through the rotation center of the second piece 22 coincides with the axis passing through the rotation center of the hinge portion 28, while remaining engaged with the rail portion 9. As a result, the leg 3 is supported rotatably with respect to the rail portion 9. In other words, the scaffolding board half 2P is supported rotatably with respect to the leg 3 (see FIG. 12). In this way, the first piece 21 moves the leg 3 to a position where it is brought close to the support frame 4, thereby releasing the engagement with the rail portion 9 and allowing the scaffolding board half 2P to rotate to the lower folding position.

As shown in Figures 1 to 7, the support frame 4 comprises front and rear side frames 24, an upper frame 25, and a lower frame 26. The side frames 24 are formed in a generally horizontal H-shape when viewed from the front (or rear), with upper rails 24A and lower rails 24B, and are provided at positions near the front and rear on the underside of the scaffolding board 2. The upper frame 25 is spanned between the upper ends of the side frames 24, and the lower frame 26 is spanned between the lower ends of the side frames 24.

The upper rail 24A of the side frame 24 is extended in the left-right direction and is disposed adjacent to the inner surface of the rail section 9 (the surface on which the groove section 9S is formed). In addition, the left and right ends of the upper rail 24A are provided with a hook hole 1H capable of hooking and holding the first plunger 11 (see FIG. 6). By hooking the tip of the first plunger 11 into the hook hole 1H, the scaffolding board half 2P can be fixed and held in a horizontal position.

The lower rail 24B of the side frame 24 extends in the left-right direction approximately parallel to the upper rail 24A. The lower rail 24B is provided at the same height as the fourth plunger 19, and has an engagement hole 4H at its left and right ends that can engage and hold the fourth plunger 19. Therefore, by moving the leg 3 approximately horizontally toward the support frame 4, the tip of the fourth plunger 19 can be engaged with the engagement hole 4H.

The upper frame 25 is horizontally supported between the front and rear upper rails 24A. Meanwhile, the lower frame 26 is horizontally supported between the front and rear lower rails 21B, and the side frames 24 are connected and held together by the upper frame 25 and the lower frame 26.

Support arms 27 are provided at positions near the front and rear ends of the upper frame 25. The support arms 27 are formed to extend in the left-right direction approximately parallel to the upper rail portion 24A. Hinge portions 28 are provided at the left and right ends of the support arms 27. A pair of support arms 27 are provided at the front and rear of the scaffolding board 2, sandwiching the center between the front and rear of the scaffolding board 2, and the scaffolding board half 2P is pivotally connected to the support frame 4 by a pair of front and rear hinge portions 28 provided on the support arms 27.

A gas spring 29 is connected to the center between the front and rear of the upper frame 25. One end of the gas spring 29 is pivotally connected to the upper frame 25, and the other end is pivotally connected to the middle frame 7 of the scaffolding board half 2P, thereby limiting the rotational force when the scaffolding board half 2P rotates from the horizontal position toward the lower folding position.

The connecting frame 5 includes a connecting arm 31, a connecting shaft 32, and a crosspiece 33. One end of the connecting arm 31 is pivotally connected to the lower frame 26 of the support frame 4, and the other end is pivotally connected to the middle crosspiece 15 on the lower end side of the leg 3. A pair of connecting arms 31 are provided at the front and rear of the scaffolding board 2, sandwiching the center between the front and rear of the scaffolding board 2, and a crosspiece 33 is horizontally supported between the connecting arms 31 at a position near the other end (near the middle crosspiece 15). In this embodiment, the lower frame 26 of the support frame 4 is provided at a position higher than the middle crosspiece 15 of the leg 3. Therefore, the connecting frame 5 extends diagonally upward from a position near the lower end of the leg 3 toward the support frame 4.

The connecting arm 31 is a member formed by connecting the ends of two long, roughly U-shaped cross-section frame materials with a connecting shaft 32, and is configured to be bent in a mountain fold at the midpoint between the left and right as shown in FIG. 5 by moving the legs 3 closer to each other in the left-right direction from the deployed position shown in FIG. 4. The connecting arm 31 is configured to be able to be held in an extended position in which it is bent slightly downward when the legs 3 are moved away from each other to the deployed position (see FIG. 4), and by extending the connecting frame 5 as described above and locking it, it is possible to prevent the legs 3 from moving unintentionally toward the support frame 4.

The folding procedure of the folding work scaffold 1 will be described. First, in the unfolded state shown in FIG. 4, the scaffold board half 2P and the leg 3 are released from the fixed state by the second plunger 12. At this time, the scaffold board half 2P is fixed and held in a horizontal position on the support frame 4 by the first plunger 11. Then, after releasing the lock state of the connecting frame 5 (bending the connecting arm 31 upward), the leg 3 is slid horizontally along the scaffold board half 2P toward the support frame 4, and the fourth plunger 19 is engaged with the engagement hole 4H provided in the lower rail 24B of the side frame 24 of the support frame 4, thereby fixing the leg 3 to the support frame 4. As a result, the folding work scaffold 1 is in a state in which the scaffold board half 2P is held in a horizontal position and the left and right legs 3 are brought together in the center between the left and right, as shown in FIG. 5.

Furthermore, from this state, the fixed state between the scaffolding board half 2P and the support frame 4 by the first plunger 11 is released, and the scaffolding board half 2P is rotated downward so as to align with the outside of the leg body 3, so as to bend downward. At this downward bending position, the second plunger 12 is engaged with the engaging hole 3H provided in the support frame 13 of the leg body 3, thereby fixing the scaffolding board half 2P to the leg body 3. As a result, the folding work scaffold 1 is fixed and held in a state in which the scaffolding board 2 is folded in a mountain fold, as shown in FIG. 6.

Conversely, when unfolding the folding work scaffold 1, the above-mentioned folding procedure is reversed. Specifically, first, the fixed state between the scaffold board half 2P and the leg 3 by the second plunger 12 is released. At this time, the scaffold board half 2P rotates a predetermined angle toward the horizontal position (in the direction of unfolding) due to the repulsive force of the gas spring 29. In other words, the scaffold board half 2P automatically moves away from the leg 3 and is held at a predetermined angle. This makes it easier for the worker to grasp the scaffold board half 2P. Then, the scaffold board half 2P is rotated to the horizontal position and fixed to the support frame 4 by the first plunger 11.

Furthermore, from this state, the fourth plunger 19 releases the fixed state between the leg 3 and the support frame 4, and the leg 3 slides away from the support frame 4 to the deployed position. The connecting frame 5 is then extended to a locked state, and the first plunger 11 fixes the leg 3 to the top plate half 2P. As a result, the folding work scaffold 1 is fixed and held in the original deployed state, as shown in FIG. 4.

As described above, the folding work scaffold 1 of this embodiment comprises a scaffold board 2 divided into left and right halves, a pair of legs 3 arranged opposite each other on the underside of the scaffold board 2 and supporting the scaffold board half 2P from below, a support frame 4 provided in a central position between the left and right sides on the underside of the scaffold board 2 and supporting the scaffold board half 2P so that it can rotate between a horizontal position and a lower folded position, and a connecting frame 5 connecting the legs 3 to the support frame 4 so that they can move toward and away from each other, and the legs 3 are connected to the scaffold board half 2P so that they can slide left and right.

With this configuration, the legs 3 can be moved stably toward and away from each other in the left-right direction of the scaffolding board 2 without being affected by the movement of the swivel wheels 17, making it possible to smoothly unfold and fold the folding work scaffolding 1.

In addition, in the folding work scaffold 1 of this embodiment, the scaffold board half 2P is provided with a rail section (guide section) 9 that guides the leg body 3 in the left-right direction, while the leg body 3 is provided with at least two pieces 21, 22 arranged side by side on the left and right that are slidably engaged with the rail section 9.

With this configuration, the legs 3 are connected to and supported by the rails 9 by the two pieces 21 and 22, so the legs 3 can be moved closer to and farther from each other in the left-right direction more stably. This makes it possible to unfold and fold the folding work platform 1 more smoothly.

In addition, in the folding work scaffold 1 of this embodiment, when the leg 3 is in a position close to the support frame 4, the first piece 21 of the above-mentioned pieces 21, 22 is released from its engagement with the rail portion 9, and the second piece 22 is engaged with the rail portion 9 and is positioned coaxially with the hinge portion (pivot portion) 28 that pivotally connects the scaffold board half 2P and the support frame 4 to each other.

With this configuration, when the leg 3 is in a position close to the support frame 4, the scaffold board half 2P is pivoted by the second link 22 and the hinge 28, so the scaffold board half 2P can be rotated more stably. This allows the folding work scaffold 1 to be unfolded and folded more smoothly.

In addition, the folding work scaffold 1 of this embodiment is provided with a first plunger (locking mechanism) 11 on the scaffold board half 2P, which can fix and hold the scaffold board half 2P in a horizontal position.

With this configuration, by fixing and holding the scaffolding board halves 2P in a horizontal position, the legs 3 can be moved closer to and farther from each other in the left-right direction of the scaffolding board 2 more stably, making it possible to unfold and fold the folding work scaffolding 1 even more smoothly.

In the above embodiment, the leg 3 is described as having two pieces 21, 22 arranged side by side, but the leg 3 may have three or more pieces arranged side by side, or the leg 3 may have only one piece (for example, the second piece 22 arranged at the tip 23A of the support plate 23).

In the above embodiment, when the leg 3 is in a position close to the support frame 4, the first piece 21 is released from its engagement with the rail 9, while the second piece 22 is positioned coaxially with the hinge 28 (pivot) that pivotally connects the scaffolding board half 2P and the support frame 4 while remaining engaged with the rail 9. However, when the leg 3 is in a position close to the support frame 4, both pieces 21 and 22 may be positioned above the notch 9H, and the engagement with the rail 9 may be released.

In the above embodiment, the first plunger 11 is provided on the rail portion 9 of the scaffolding board half 2P as a locking mechanism for fixing and holding the scaffolding board half 2P in a horizontal position. However, the support frame 4 may be provided with a locking mechanism for fixing and holding the scaffolding board half 2P in a horizontal position.

In the above embodiment, a pair of legs 3 arranged on the left and right sides are described as being configured to support the scaffolding board half 2P from below, but the support frame 4 may further be provided with one or more auxiliary legs that support the scaffolding board half 2P from below, and the legs 3 and the auxiliary legs may support the scaffolding board half 2P from below. Alternatively, the support frame 4 may be extended to the same position as the lower end of the legs 3, and the legs 3 and the support frame 4 may be configured to support the scaffolding board half 2P from below.

In more detail, in the folding work scaffold 1, auxiliary legs are provided at the center between the left and right of the lower rails 24B of the front and rear side frames 24 of the support frame 4, or at the front and rear ends of the bottom frame 26 of the support frame 4. Alternatively, one auxiliary leg is provided at the center between the front and rear of the bottom frame 26 of the support frame 4. In this case, the auxiliary frame is preferably configured to be adjustable in vertical length, similar to the leg 3. In addition, swivel wheels are provided at the lower end of the auxiliary frame.

Alternatively, in the folding work scaffold 1, the front and rear side frames 24 of the support frame 4 are each extended to the same position as the lower end of the leg body 3. In this case, the side frames 24 are preferably configured to be adjustable in length up and down, just like the leg body 3. In addition, swivel wheels are provided on the lower rail portion 24B of the side frames 24.

With these configurations, the inner ends of the scaffolding board halves 2P (the center side between the left and right sides of the scaffolding board 2) are supported by the support frame 4, so the legs 3 can be moved closer to and farther from each other in the left and right direction of the scaffolding board 2 more stably. This makes it possible to unfold and fold the folding work scaffolding 1 more smoothly.
