Description

[Technical Field]

[0001] The present invention relates to a deck facility in which a deck section is installed above ground where workers can pass through in order to get on and off a moving object such as a moving truck or a railway vehicle. [Background technology]

[0002] To make it easier for workers to get on and off the truck bed, a deck supported by a base is installed at a height similar to that of the truck bed. This deck allows workers to move between the ground level and the deck, for example, by using stairs on the deck equipment.

[0003] When a truck stops at a predetermined distance to the side of the deck, if the distance between the deck and the truck is too large, it is difficult to transfer from the deck to the truck. To address this issue, conventional deck facilities require temporary scaffolding such as ladders to be set up from the deck toward the truck, making it easier for passengers to get on and off the truck.

[0004] However, the distance between the truck and the deck varies depending on where the truck is parked. Considering this, constructing temporary scaffolding accordingly is time-consuming. Furthermore, there is a problem in terms of safe transfer, such as the creation of a step between the deck floor and the scaffolding.

[0005] Conventional examples of this include deck equipment described in Patent Documents 1 and 2. Patent Document 1 describes a configuration in which all or part of the deck is a slidable movable deck that can slide toward the truck, thereby eliminating a step between the deck and the truck bed and reducing the gap between the truck and the deck. Furthermore, Patent Document 2 describes providing a movable platform, which is a platform that can be moved toward the truck, below the deck. In other words, by extending the movable platform toward the truck bed, it is possible to easily accommodate the gap between the truck and the deck. However, Patent Document 2 does not describe or suggest making the deck itself movable, as in the present invention. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 7015099 [Patent Document 2] Japanese Patent Application Publication No. 2018-020906 Summary of the Invention [Problem to be solved by the invention]

[0007] In Patent Document 1, a worker steps on a pedal provided on the movable deck to unlock it, and then operates a handle provided on the movable deck to move the movable deck with the worker on it toward the truck. However, because the movable deck needs to be moved from a state in which the worker is on the movable deck and there is a gap between it and the truck, a safety handrail needs to be provided on the tip of the movable deck.

[0008] Furthermore, when the movable deck section is moved, a gap is formed behind the movable deck, making it difficult for workers to move between the movable deck section and the fixed deck section that is not the movable deck section. Furthermore, if the end of the movable deck section is located at the longitudinal end of the deck section, it is difficult for workers to move between the deck section and the above-ground section via the stairs.

[0009] On the other hand, the deck equipment of Patent Document 2 does not assume that the deck section itself is movable. Furthermore, workers who climb the stairs onto the deck section can move between the truck bed and the deck section by sliding the movable platform on the deck section and using the movable platform that protrudes from the truck side. However, there is a step between the top surface of the movable platform and the top surface of the deck section, which means that there is a risk that workers will trip on the step when moving around with luggage. Furthermore, in Patent Document 2, the movable platform corresponds to the conventional hypothetical scaffolding, and there is no idea of ​​connecting the sliding movable platform to a staircase.

[0010] Furthermore, Patent Documents 1 and 2 do not describe a method of sliding a deck section as a passageway by operating it from above ground.

[0011] The present invention has been made in light of the above-mentioned points, and aims to make it easy to transfer from the ground section to the moving body via the deck section using a simple mechanism. [Means for solving the problem]

[0012] In order to solve the problem, one aspect of the present invention is a deck equipment having a deck section for workers to get on and off a moving vehicle, the deck equipment comprising: a base section installed on the floor section to support the deck section; and a staircase for ascending and descending that connects the above-ground section to the deck section, wherein at least a portion of the deck section is a movable deck section that can slide laterally from an initial position on the base section toward the moving vehicle so as to protrude from the base section, and the staircase is connected to the movable deck section and is configured to be slidable together with the movable deck section.

[0013] The operator for operating the slide of the movable deck section is preferably located in a position where it can be operated by an operator on the floor above ground. [Effects of the Invention]

[0014] According to this aspect of the present invention, the stairs move together with the movable deck section, making it easy to transfer from the ground section to the moving body. Even if part of the deck is made into a movable deck, the stairs move together with the movable deck, so even if the movable deck is slid toward the moving body, movement from the ground level to the movable deck can be carried out safely and smoothly.

[0015] Furthermore, by moving the movable deck section itself, no step is formed, as in Patent Document 2, between the deck section and the movable platform, and movement from the deck section to the moving body can be carried out safely. [Brief explanation of the drawings]

[0017] Next, an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a truck (industrial vehicle) will be described as an example of a moving body, however, the moving body is not limited to an industrial vehicle.

[0018] (composition) As shown in Fig. 1, the deck equipment 101 of this embodiment has a deck section 2 (floor section). The deck section 2 runs on the surface of an above-ground section 102 and serves as a passageway for workers to get on and off the bed of a truck 100 parked at a predetermined position. A floor surface 2a, which is the upper surface of the deck section 2, is installed on a base section 1 so that it is at the same height as the bed of the truck 100, for example. 2 and 3, the deck section is configured so that the side facing the track 100 is the width direction and the deck section extends in a direction perpendicular to the width direction. In this specification, the direction perpendicular to the lateral direction, which is the sliding direction, is sometimes referred to as the longitudinal direction. The lateral direction corresponds to the width direction of the deck section 2.

[0019] The deck equipment 101 of this embodiment is provided with a slide mechanism that enables the deck section 2 itself to slide laterally (towards the parked truck 100) relative to the base section 1. In this example, the entire deck section 2 constitutes one movable deck section. The slide mechanism allows the deck section 2 to slide laterally (to the left in FIG. 1) from its initial position on the base section 1 (the position indicated by the dashed line on the right end in FIG. 1) in a direction that protrudes from the base section 1 toward the parked truck 100. A bumper 2b made of an elastic material is provided at the tip of the deck section 2 to prevent scratches on the truck 100 when the tip of the deck section 2 comes into contact with it.

[0020] As shown in FIG. 1, the slide mechanism of this embodiment includes a first guide rail 3, a first wheel 4, a second guide rail 5, and a second wheel 6. The first guide rail 3 is fixed to the deck portion 2 and extends in the sliding direction (lateral direction). The first wheel 4 is rotatably fixed to the base portion 1 and is guided by the first guide rail 3 so as to be able to roll on the first guide rail 3 in the sliding direction.

[0021] The second guide rail 5 is fixed to the base 1 and extends in the sliding direction. The second wheel 6 is fixed to the deck 2 and is guided by the second guide rail 5, so that it can roll on the second guide rail 5 in the sliding direction.

[0022] The first wheel 4 is positioned closer to the overhang side than the second wheel 6, thereby increasing the amount of overhang that the sliding deck section 2 can have. From the perspective of setting a large amount of overhang, it is preferable to provide the first wheel 4 at the end of the base section 1 on the overhanging direction side, and the second wheel 6 at the end of the deck section 2 on the opposite side to the overhanging direction, as shown in Figure 1. In Fig. 1, reference numeral 7 denotes a roller that constitutes a mechanism for preventing the deck section 2 from lifting up. The roller 7 is in rolling contact with the rail surface that is the lower surface of the beam extending in the width direction of the base section 1 from below.

[0023] As will be described later, the vehicle also has a pedal 8 of a locking mechanism. The pedal 8 is located near the above-ground portion 102. When the pedal 8 is pressed, the sliding lock of the deck section 2 is released, and when the pedal 8 is not pressed, the deck section 2 is restricted from moving in the sliding direction.

[0024] The deck equipment 101 of this embodiment also has a handle 9 as a drive operator that instructs the drive amount and slide direction to the drive mechanism. The handle 9 is supported on the base or on a frame (not shown) provided on the ground, and can be operated from above ground. When a worker on the ground steps on pedal 8 and operates handle 9 while the locking mechanism is released, the drive mechanism is driven according to the amount and direction of rotation of handle 9, causing deck section 2 to slide sideways relative to base section 1. In this manner, in this embodiment, the deck section 2 can be slid by one worker operating it from the ground section 102.

[0025] Reference numeral 10 denotes a handrail provided at the rear end of the deck section 2. Reference numeral 11 denotes a balance weight that prevents the base section 1 from lifting up.

[0026] The deck equipment 101 of this embodiment will be described in more detail below. As shown in FIGS. 2 and 3, the deck equipment 101 of this embodiment includes a base 1, a deck 2 installed on the base 1, and a staircase.

[0027] <Base> The base 1 is composed of a combination of frameworks such as columns 1A and beams 1B. This allows workers to see the area around the deck equipment 101, particularly the parked trucks 100, from behind the base 1. <Deck section> The deck section 2 is supported by the base section 1. The floor surface 2a of the deck section 2 extends in the longitudinal direction, perpendicular to the sliding direction (the paper surface direction in FIG. 2, the up-and-down direction in FIG. 3), to form a passageway. Stairs 11 are provided on both the left and right sides of the deck section 2, allowing access from the ground of the above-ground section 102 to the floor surface 2a of the deck section 2.

[0028] As described above, this example illustrates a case where the entire deck section 2 is a movable deck section. The deck section 2 may be divided into a plurality of sections along the longitudinal direction, and each section may be individually provided with a slide mechanism, a lift-up prevention mechanism, a locking mechanism, a drive mechanism, and the like. Also, a part of the deck section 2 may be a fixed deck section that cannot slide, but a part of the movable deck section is integrally connected to the stairs 11 as described above.

[0029] <stairs> The stairs 11 in this embodiment are integrally connected to the longitudinal ends of the deck section 2. In this example, the entire deck section 2 constitutes the movable deck section. Therefore, the stairs 11 are structured to be integrally connected to the movable deck section 2. The stairs 11 are also configured to be slidable laterally together with the deck section 2. In this example, the left and right stairs 11 are integrally connected to the deck section 2, but only one of the left and right stairs 11 may be slidably connected to the deck section 2.

[0030] 2 and 4, the staircase 11 includes a step portion 11A that workers ascend and descend, and a framework portion that supports the step portion 11A. The framework portion includes a horizontal portion 11C and a vertical portion 11B. The horizontal portion 11C is a horizontal member that extends from the lower portion of the step portion 11A toward the base portion 1. The vertical portion 11B is a vertical member that connects the upper portion of the step portion 11A and the base-side end portion of the horizontal portion 11C.

[0031] The vertical portion 11B is disposed opposite the pillar 1A located at the longitudinal end of the base portion 1 and the longitudinal end of the deck portion 2 in the longitudinal direction. 4, the upper part of the vertical part 11B is integrally connected to the end of the deck part 2 by known joining processes such as welding or bolting. In other words, the staircase 11 has a structure in which the upper part is integrally connected to the deck part 2.

[0032] [Staircase sliding mechanism] As shown in FIG. 4, a staircase slide mechanism is provided between the base 1 and the vertical portion 11B of the staircase 11, allowing the staircase 11 to slide laterally relative to the base 1.

[0033] Next, the stair sliding mechanism of this embodiment will be described with reference to FIG. In this embodiment, stair slide mechanisms are provided in two locations.

[0034] The first stair slide mechanism will be described. A roller 14 is provided at a position that protrudes from the vertical portion 11B toward the base. The roller 14 is attached to the vertical portion 11B by a bracket 15. The roller 14 is fixed to the bracket 15 so as to be rotatable about a vertical axis.

[0035] Furthermore, rails 12 extending in the width direction are provided between a plurality of pillars 1A arranged in the width direction at the longitudinal ends of the base 1. The width direction corresponds to the lateral direction. The rail 12 is provided at a height that allows it to face the rolling surfaces (outer peripheral surfaces) of the rollers 14, and the rollers 14 are configured to be able to roll along the surface of the rail. The rail 12 may have a U-shaped or L-shaped cross section with an overhang on the staircase side to prevent the rollers 14 from coming off.

[0036] The second stair slide mechanism will now be described. Rails 13 extending in the width direction are provided between the upper ends of multiple pillars 1A arranged in the width direction at the longitudinal ends of the base 1. The rails 13 extend in the width direction with the rail surface facing upward.

[0037] The rail 13 also includes rollers 16 that can roll in the width direction along the rail 13. The rollers 16 are fixed to brackets 17 with their rotation axes facing the longitudinal direction of the base 1. The brackets 17 are fixed to the vertical portion 11B. The rail 13 may have a U-shaped or L-shaped cross section with an upward protrusion to prevent the rollers 16 from coming off.

[0038] 4, the upper part of the stairs 11 is connected to the deck section 2, and the load is supported by the upper end of the deck section 2. Furthermore, the second staircase sliding mechanism allows the load of the stairs 11 to be supported by the columns 1A of the stairs 11 in a state where the stairs 11 can also slide laterally on the upper part of the base section 1.

[0039] Furthermore, because the upper part of the stairs 11 is supported by the deck part 2, a moment is generated that moves the lower side of the stairs 11 closer to the base part 1. This moment causes the rollers 14 to be in rotatable contact with the rails 12 that constitute the first stair slide mechanism. As described above, the staircase 11 of this embodiment is configured by the staircase sliding mechanism to be able to slide laterally relative to the base 1. Note that wheels that can be guided by the ground portion and move in the width direction may be provided at the lower end of the staircase 11.

[0040] <Slide mechanism> Next, a slide mechanism that allows the movable deck section 2 to slide will be described. In this embodiment, the slide mechanisms are installed at two or more locations spaced apart from each other in the longitudinal direction of the deck section 2 to be slid.

[0041] The slide mechanism transmits the load of the deck section 2 to the base section 1, and is therefore positioned so that it overlaps the pillars 1A vertically when viewed from the front, as shown in Figure 2. Specifically, the slide mechanism is positioned between the beam 1D spanning the left and right pillars 1A and the underside of the deck section 2 located above it, as shown in Figure 5.

[0042] As described above, the slide mechanism includes the first guide rail 3, the first wheel 4, the second guide rail 5, and the second wheel 6. In this embodiment, as shown in Fig. 5, the first guide rail 3 and the second guide rail 5 are arranged so as to overlap each other vertically.

[0043] As shown in Fig. 5, the first guide rail 3 is fixed to the underside of the deck section 2 and extends in the sliding direction (lateral direction). In this embodiment, the first guide rail 3 is made of equal-leg angle steel and is arranged with the corners of the angle facing downward, as shown in Fig. 5(b).

[0044] The first wheel 4 is installed on the upper side of the pillar 1A of the base 1. In this embodiment, the first wheel 4 is made up of an angle rail wheel, and is guided by the first guide rail 3 so as to be able to roll on the first guide rail 3 in the sliding direction.

[0045] As shown in Fig. 5, the second guide rail 5 is fixed between the upper portions of the front and rear pillars 1A that make up the base 1, and extends in the sliding direction (horizontal direction). In this embodiment, the second guide rail 5 is made of equal-leg angle steel, and is arranged with the corners of the angle facing upward, as shown in Fig. 5(c).

[0046] The second wheels 6 are installed on the underside of the deck section 2. In this embodiment, the second wheels 6 are made up of angle rail wheels, and are guided by the second guide rails 5 so as to be able to roll on the first guide rails 3 in the sliding direction.

[0047] The slide mechanisms are provided at two locations on the underside of the deck section 2. As a result, the deck section 2 can slide laterally from its initial position (FIG. 5(a)) on the base section 1 toward the truck 100 so as to overhang the base section 1, as shown in FIG.

[0048] <Floating prevention mechanism> It is provided with a lift-up prevention mechanism that prevents the deck part 2 from lifting up from the base part 1. In this embodiment, as shown in FIGS. 1 and 6, lift-up prevention mechanisms are provided on both the left and right sides (outside the slide mechanisms) between the deck section 2 and the base section 1.

[0049] The lift-up prevention mechanism includes a roller 7 rotatably supported on the deck portion 2, and a rolling surface that is provided on the base portion 1, extends laterally, and against which the roller 7 rotatably abuts from below.

[0050] In this embodiment, as shown in Fig. 6, a channel steel 1E is arranged as a beam member connected between the front and rear columns 1A and with its axis facing the front-to-rear direction (sliding direction). The channel steel 1E is arranged so that its lower web portion is horizontal, and the lower surface of the web portion becomes the above-mentioned rolling surface. The beam member that forms the rolling surface does not have to be the channel steel 1E.

[0051] As shown in Figure 6, the deck section 2 has a bracket 71 that is fixed at its upper end to the deck section 2 and extends downward, with a shafted roller 7 attached to the lower end of the bracket 71. The roller 7 is attached to the bracket 71 so as to project downward from the bracket 71 from the channel steel 1E, and the roller 7 abuts the rolling surface from below so that it can roll. As a result, the roller 7 moves along the lower surface (rolling surface) of the channel steel 1E in response to the sliding of the deck section 2, and when the deck section 2 attempts to displace upward relative to the base section 1, the upward movement of the roller 7 is restricted by the rolling surface, preventing the deck section 2 from lifting up.

[0052] <Locking mechanism> A locking mechanism is provided to restrict movement of the deck section 2 relative to the base section 1 in the sliding direction. The locking mechanism is a mechanism that connects the deck section 2 to the base section 1 in an unloaded state, and restricts the sliding of the deck section 2. This state is the locked state. Furthermore, when an operator steps on the pedal 8, causing the pedal 8 to be displaced upward, the locking mechanism is released from the locked state, allowing the deck section 2 to slide relative to the base section 1. Releasing the locked state refers to releasing the connection between the deck section 2 and the base section 1.

[0053] This prevents the deck section 2 from sliding unintentionally when workers pass over the floor surface 2a of the deck section 2. Furthermore, when a worker wants to slide the deck section 2 in the above-ground section 102, the deck section 2 can be slid by the simple action of stepping on the pedal 8.

[0054] The locked state is released when the deck section 2 is slid, so the pedal 8 is preferably located near and below the handle 9, which is the driving operator.

[0055] As shown in FIGS. 7 and 8, the locking mechanism of this embodiment includes a pedal 8, a rack portion 83, a spring member, upper and lower members 82, and a meshing portion 84. [pedal] Pedal 8 is disposed near ground portion 102 on the rear side of base 1. Pedal 8 is connected to one end of first rod 87, and the other end of first rod 87 is connected to the lower end of second rod 88. The axis of first rod 87 is disposed in the width direction of base 1 or diagonally along the width direction in top view. The first rod 87 is connected at its longitudinal midpoint to a beam 1C of the base 1, and is rotatable up and down around this connecting portion. The beam 1C forms the framework of the lower part of the base 1 and extends in the width direction.

[0056] The second rod 88 extends toward the lower end of the upper and lower members 82 of the locking mechanism, and has its upper end connected to the lower end of the upper and lower members 82 .

[0057] With this configuration, the locking mechanism is configured so that when the pedal 8 is depressed, the other end of the first rod 87 is displaced upward, causing the upper end of the second rod 88 to also be displaced upward. When the pedal 8 is released from depression, the pedal 8 rises to its initial position due to, for example, the weight balance of the first rod 87, the second rod 88, and the pedal 8. The weights of the first rod 87 and the second rod 88 are added to the locking mechanism.

[0058] [Rack section] The rack section 83 is supported by a cross member 2C at the bottom of the deck section 2 and extends in the sliding direction. The rack section 83 has multiple teeth aligned in the sliding direction with the teeth facing upward.

[0059] [Upper and lower parts] The upper and lower members 82 are supported by brackets 81 attached to beams 1B of the base 1. The support structure is such that a protruding portion 82a protruding from the upper and lower members 82 and a protruding portion 81a protruding from the bracket 81 are arranged facing each other at the top and bottom. A coil spring 85 is arranged between the two opposing protruding portions 82a, 81a as a spring member with its axis facing up and down. The coil spring 85 is a compression coil spring, and exerts a spring force (biasing force) in a direction that brings the opposing protruding portions 82a, 81a closer together. This causes the upper and lower members 82 to be displaced downward with a predetermined spring force.

[0060] Additionally, a meshing portion 84 is fixed to the upper portion of the upper and lower members 82. The meshing portion 84 protrudes from the upper and lower members 82 toward the rack portion 83, and faces the rack portion 83 from above and below. The meshing portion 84 has meshing teeth on its underside that can mesh with the teeth of the rack portion 83. The upper end of the second rod 88 is connected to the lower end of the upper and lower members 82 .

[0061] Then, due to the spring force of the coil spring 85, the interlocking teeth of the interlocking portion 84 come into contact with and interlock with the teeth of the rack portion 83, as shown in Figures 7(a) and 8(a), thereby entering a locked state and restricting the amount of downward displacement of the upper and lower members 82.

[0062] When the pedal 8 is depressed from this locked state and displaces downward against the spring force of the coil spring 85, the meshing portion 84 displaces upward as shown in Figures 7(b) and 8(b). This disengages the meshing portion 84 from the rack portion 83, allowing the deck portion 2 to slide. The rod body 86 is a component that regulates the amount of upward displacement of the vertical member 82.

[0063] <Drive mechanism> A drive mechanism is provided to drive the deck section 2 in a sliding direction relative to the base section 1. The drive mechanism includes, for example, a gear rotatably supported on the base portion 1, and an interlocking rail fixed to the lower portion of the deck portion 2, with interlocking portions that interlock with the gear teeth aligned along the sliding direction.

[0064] As shown in FIGS. 8 and 9, the drive mechanism of this embodiment includes a handle 9 as a drive operator, a transmission mechanism, a sprocket 94 constituting a gear, and a roller chain 95 constituting an interlocking rail.

[0065] The handle 9 has its shaft rotatably supported on the base 1 and is located at the rear in the width direction of the base 1. In a top view, the handle 9 is provided near the pedal 8 and is located in a position where an operator on the above-ground part 102 can turn the handle 9 while operating the pedal 8 with his foot. The rotation of the handle 9 can be transmitted to the sprocket 94 by a transmission mechanism 99 .

[0066] The transmission mechanism of this embodiment includes a shaft member 91 extending in the sliding direction, and a worm reducer 93 that transmits the axial rotation of the shaft member 91 to a sprocket 94. Rotation of the handle 9 around the horizontal axis is transmitted to the shaft member 91, and rotation of the shaft member 91 around the axis in the sliding direction is converted by a worm reducer 93 into rotation around the horizontal axis perpendicular to the sliding direction and transmitted to a sprocket 94. Reference numeral 92 denotes a coupling.

[0067] Here, for ease of understanding, the handle 9 is shown directly behind the worm reducer 93, but it is preferable that the handle 9 be located near the stairs 11. For this reason, as shown in Figure 2, the shaft member 91 connected to the worm reducer 93 comprises a first shaft member extending along the longitudinal direction of the base 1, and a second shaft member connected to the first shaft member and extending in the width direction, and the handle 9 is connected to the second shaft member. 9, the handle 9 is disposed at the rear of the longitudinal end of the base 1. The pedal 8 is also disposed on the staircase 11 side.

[0068] In this embodiment, two sprockets 94 are provided, and as shown in FIG. 10, the two sprockets 94 are arranged on both the left and right sides of the worm reducer 93. A roller chain 95 that meshes with each sprocket 94 is provided on the deck section 2 side. The roller chain 95 is disposed so as to extend in the sliding direction.

[0069] As a result, rotation of the handle 9 rotates the sprockets 94, and the left and right sprockets 94 engage with the roller chains 95, thereby generating a driving force that moves the deck section 2 in the sliding direction relative to the base section 1.

[0070] 2, the drive unit main body of the drive mechanism is disposed in the center of the deck unit 2 in the left-right direction when viewed from above. The drive unit main body includes a worm reducer 93, a sprocket 94, a roller chain 95, and the like. The mechanism of the drive unit body of the drive mechanism is not limited to the combination of a sprocket 94 and a roller chain 95. For example, as shown in Figure 10, it may be composed of a combination of a rack 111 and a pinion gear 110. It may also be composed of a cylinder device with its axis facing the sliding direction.

[0071] Furthermore, although the example shows a case where the drive unit main body has a mechanical structure, it may be configured to be driven by an electric or hydraulic circuit. In this case, the drive operator does not have to be the handle 9. The drive operator may be configured as a stick or operation button that supports forward and backward movement.

[0072] (Operation etc.) In the deck equipment 101 of this embodiment, a worker depresses the pedal 8 on the ground section 102 to release the locking mechanism. In this released state, the worker turns the handle 9 to slide the deck section 2 from its initial position toward the stopped truck 100. Once the deck section 2 has slid to the desired position, the worker releases the pedal. This restrains the protruding deck section 2 in that position and locks it so that it does not slide.

[0073] In this embodiment, the deck section 2 and the stairs 11 are integrally connected and have a staircase sliding mechanism, so that the stairs 11 also move toward the truck 100 in synchronization with the extension of the deck section 2. Thereafter, the worker climbs the stairs 11 to the deck section 2 and performs the work of transporting the load beside the truck bed.

[0074] In this way, after the gap between the deck section 2 and the bed of the truck 100 is reduced to zero or small, the worker moves onto the sliding deck section 2 using the stairs 11. Therefore, it does not matter if there is no safety handrail on the truck 100 side of the movable deck section 2. In this embodiment, the deck section 2 itself slides, making it easier to transfer from the deck section 2 to the truck 100.

[0075] Furthermore, by changing the amount of sliding of the deck unit 2 itself depending on the stopping position of the truck 100, it becomes easier to transfer from the deck unit 2 to the truck 100 depending on the stopping position of the truck 100. In particular, in this embodiment, since the deck unit 2 itself slides, no steps are formed in the movement path between the deck unit 2 and the truck.

[0076] Furthermore, since the stairs 11 can slide integrally with the deck section 2, workers can move smoothly from the above-ground section 102 to the slid deck section 2.

[0077] As described above, in this embodiment, the stairs 11 move together with the movable deck section 2, making it easy to transfer between the above-ground section 102 and the movable body. Even if part of the deck section 2 is the movable deck section 2, because the stairs 11 move together with the movable deck section 2, even if the movable deck is slid toward the movable body, movement from the above-ground section 102 to the movable deck section 2 can be performed safely and smoothly.

[0078] Furthermore, by moving the movable deck section 2 itself, no step is formed between the deck section and the movable platform as in Patent Document 2. The step is formed because of the idea of ​​temporarily placing a separate scaffold between the deck section 2 and the bed of the truck 100.

[0079] (Variation) As shown in Fig. 12(a), two deck equipment 101 may be configured so that the handrails 10 are on the inside and aligned in the width direction. The entire deck section 2 of each of the two deck equipment 101 is configured as a movable deck section. A handle 9 and pedals (not shown) are provided for each deck facility 101. Although the handle 9 and pedals are provided on the right side in Fig. 12(a), they may be provided near the stairs on the left side. In the case of Figure 12, when work is performed on the truck 100 on both sides of the width of the deck equipment, the gap between the deck section 2 and the truck 100 can be individually reduced, allowing each work to be performed individually.

[0080] 12, the left staircase 11X is provided for each deck equipment 101 and is configured to be integrally connected to the corresponding deck section 2. The right staircase 11Y is not integrally connected to the deck section 2, but is a staircase shared by the two deck sections 2.

[0081] 12, the handrails 10 of the two left and right deck equipment 101 are not provided at the right end. That is, the handrails 10 are provided from the left end to just before the right end (for example, at a position 2 m away from the right end). This allows a worker who has climbed up the right staircase 11Y to easily move to either deck section 2 of the left or right deck equipment 101.

[0082] In this case, when at least one of the left and right deck sections 2 is slid in the projecting direction (see FIG. 12(b)), the left staircase 11X moves in the projecting direction in synchronization with the deck section 2. On the other hand, the right staircase 11Y is in a fixed position as shown in FIG. 12(b), so it is difficult to move to the slid deck section 2 using the right staircase 11Y. Taking this into consideration, a common floorboard section 103 is provided on the right side between the deck section 2 and the base section 1, that is, below the two left and right deck sections 2. A staircase 11Y is then connected to this floorboard section 103. This allows access to the slid deck section 2 using the staircase 11Y on the right side.

[0083] (others) The present disclosure can also be configured as follows. (1) Disclosure 1 is a deck facility having a deck section for workers to get on and off a moving vehicle, a base portion installed on the ground and supporting the deck portion; an ascent and descent staircase connecting the above-ground portion and the deck portion; Equipped with at least a portion of the deck section is a movable deck section that can slide laterally from an initial position on the base section toward the moving body so as to protrude from the base section, The staircase is integrally connected to the movable deck portion and configured to be slidable laterally together with the movable deck portion. Deck facilities.

[0084] According to this configuration, the deck section itself is slidable toward the moving body, so no step is formed on the floor surface between the deck section and the moving body, and a simple mechanism makes it easy to transfer between the deck section and the moving body. In addition, the stairs move together with the deck, allowing for smooth movement from the ground level to the mobile unit position.

[0085] (2) Disclosure 2 discloses that the base portion has a rail portion extending in the horizontal direction on a surface facing the stairs, The steps have rollers that contact the rail portions and are capable of rolling along the rail portions. With this configuration, when the movable deck section moves, the stairs can also move reliably in synchronization. When the deck section and the top of the stairs are connected, a moment is generated around the support point at the top of the stairs toward the base. This moment is used to bring the rollers into contact with the rail section.

[0086] (3) Disclosure 3 provides a slide mechanism that allows the movable deck section to slide laterally relative to the base section; a drive mechanism that drives the movable deck section in the lateral direction relative to the base section; a drive operator supported on the base or the ground portion and operable from the ground portion; a transmission mechanism that mechanically transmits the operation amount of the drive operator to the drive mechanism; Equipped with The drive mechanism is driven by operating the drive operator.

[0087] With this configuration, the movable deck section can be moved toward the mobile body on the ground to reduce the gap between the mobile body and the movable deck section, and then workers can move using the stairs and the deck section. In this case, there is no need to install handrails on the mobile body side of the movable deck section.

[0088] (4) Disclosure 4 states that the drive mechanism is a gear rotatably supported on an upper portion of the base; an interlocking rail provided on a lower portion of the movable deck portion, the interlocking rail having interlocking portions that interlock with the gear teeth and that are aligned along the lateral direction; Equipped with The transmission mechanism transmits to the gear an amount of rotation corresponding to an amount of operation of the drive operator.

[0089] (5) Disclosure 5 states that the slide mechanism is a first guide rail fixed to the movable deck portion and extending in the lateral direction; a first wheel fixed to the base and guided by the first guide rail; a second guide rail fixed to the base portion and extending in the lateral direction; a second wheel fixed to the deck portion and guided by the second guide rail; Equipped with In the lateral direction, the first wheel is disposed on the protruding side relative to the second wheel. According to this configuration, the deck section can be made slidable with a simple mechanism.

[0090] (6) Disclosure 6 includes a locking mechanism that restricts the lateral movement of the deck section relative to the base section, The locking mechanism is a pedal arranged near the drive operator and operable from the ground; a rack portion provided on the movable deck portion, extending in the lateral direction and having teeth facing upward; a meshing portion having meshing teeth facing downward and capable of meshing with the teeth of the rack portion; upper and lower frames connected to the mating portion and extending downward; a guide bracket provided on the base portion and configured to guide the upper and lower frames in the up and down direction; a spring member that biases the upper and lower frames downward; a displacement transmission mechanism having one end connected to the lower part of the upper and lower frames and the other end connected to the pedal, which displaces the upper and lower frames upward against the bias of the spring member when the pedal is depressed; Equipped with When the pedal is displaced upward by the spring force of the spring member, the meshing teeth mesh with the teeth of the rack portion.

[0091] This configuration prevents the deck from sliding accidentally unless it is intended to slide. As a result, even if the deck is configured to be slidable, it does not become an obstacle when passing over the deck. In addition, the lock can be released only when sliding the deck on the ground.

[0092] (7) Disclosure 7 is a deck facility having a deck section for workers to get on and off a moving vehicle, a base portion installed on the ground and supporting the deck portion; A staircase for ascending and descending that connects the ground level with the deck above, a slide mechanism that allows a movable deck portion constituting at least a part of the deck portion to slide laterally relative to the base portion; a drive mechanism that drives the movable deck portion in the lateral direction relative to the base portion; a drive operator supported on the base or the ground portion and operable from the ground portion; a transmission mechanism that mechanically transmits the operation amount of the drive operator to the drive mechanism; Equipped with Deck facilities.

[0093] (8) Disclosure 8 includes a locking mechanism that restricts the lateral movement of the deck section relative to the base section, A pedal as an operator for operating the locking mechanism is disposed in the vicinity of the drive operator and at a position operable on the ground.
