Summary of the Invention

Problems to be Solved by the Invention

[0005] In this case, in a gaming place, chairs are often fixed to the floor surface in front of the pedestal. When the lift device is moved in the direction approaching the pedestal, the loading platform on which the gaming machine is placed interferes with the chairs in front of the pedestal. Therefore, the gaming machine can only be transported to a position farther from the pedestal than the chairs. Therefore, the distance until the gaming machine is installed on the pedestal by hand becomes long, and the work of installing the gaming machine on the pedestal is heavy labor.

[0006] Therefore, the present invention provides a lift device capable of transporting a load such as a gaming machine placed on a loading platform to a location very close to the destination of transportation such as a platform island.

[0007] The lift device for solving the above problems has the following characteristics.

[0008] That is, the lift device includes a mast portion having a leg frame extending in the front-rear direction, front wheels and rear wheels attached to the leg frame, and a mast frame extending upward from the leg frame, a lifting frame supported by the mast frame so as to be movable up and down, and a load receiving portion having a loading platform supported by the lifting frame and capable of placing a load thereon. The loading platform has a first support frame extending upward from the lifting frame, a first loading platform extending forward from the middle part in the vertical direction of the first support frame, a second support frame extending downward from the front part of the first loading platform, and a second loading platform extending forward from the second support frame below the first loading platform.

[0009] Thereby, the load placed on the loading platform of the lift device can be transported to a location very close to the destination of transportation, and the load can be easily carried from the loading platform to the destination of transportation.

[0010] Further, it includes a case attached to the loading platform and a load tightening reel having a belt wound and housed in the case and biased in the winding direction.

[0011] Thereby, the load tightening operation of the load placed on the loading platform can be easily performed by one operator.

[0012] Further, the loading platform includes a first fixing portion located at one end in the left-right direction of the first support frame and a second fixing portion located at the other end in the left-right direction of the first support frame, and the load tightening reel is detachably attached to at least one of the first fixing portion and the second fixing portion.

[0013] Accordingly, when performing the lashing operation on the load placed on the loading platform, the attachment position of the lashing reel can be appropriately selected from the first fixing portion and the second fixing portion according to the ease of operation and the working environment such as the working space, and the lashing operation can be facilitated.

[0014] Further, the load is a gaming machine.

[0015] Thereby, the labor required for the installation work of the heavy gaming machine at the conveyance destination can be effectively reduced.

[0021] The mast portion 2 has a leg frame 21, front wheels 22, rear wheels 23, a mast frame 24, and a handle 25.

[0022] The leg frame 21 is a frame member that extends in the front-rear direction as a whole. The leg frame 21 has a pair of left and right front leg frames 211 that extend in the front-rear direction, a connecting frame 212 that extends in the left-right direction and connects the rear end portions of the pair of front leg frames 211, and a pair of left and right rear leg frames 213 that extend rearward from the left and right end portions of the connecting frame 212.

[0023] The front wheels 22 are attached to the front end portions of the front leg frames 211, and the rear wheels 23 are attached to the rear end portions of the rear leg frames 213. The mast portion 2 is configured to be able to travel by the front wheels 22 and the rear wheels 23.

[0024] The mast frame 24 is a frame member that extends in the vertical direction as a whole. The mast frame 24 has a pair of left and right vertical frames 241 that extend upward from the connecting frame 212 of the leg frame 21, an upper frame 242 that extends in the left-right direction and connects the upper end portions of the pair of vertical frames 241, and an intermediate frame 243 that extends in the left-right direction and connects the intermediate portions in the vertical direction of the pair of vertical frames 241. The vertical frames 241 are arranged inside the left and right of the rear leg frames 213.

[0025] The handle 25 is provided on the left and right vertical frames 241 of the mast frame 24, and protrudes rearward and laterally outward from the vertical frame 241. The handle 25 is supported at the upper part of the vertical frame 241. The handle 25 is a gripping part that is gripped by an operator when operating the lift device 1 to travel.

[0026] The load receiving part 3 is supported by the mast frame 24 so as to be able to move up and down, and has a lifting frame 31 and a loading platform 32. The lifting frame 31 is supported by the vertical frame 241 of the mast frame 24 so as to be able to move up and down. The loading platform 32 is supported by the lifting frame 31 and is configured to be able to place loads.

[0027] The loading platform 32 is supported by the lifting frame 31, and has a pair of left and right first support frames 321 extending upward from the lifting frame 31, a pair of left and right first loading platforms 322 extending forward from the middle part in the vertical direction of the first support frame 321, a pair of left and right second support frames 323 extending downward from the front end part of the first loading platform 322, a second loading platform 324 extending forward from the lower end part of the second support frame 323, and a fitting 325 for a hook attached to the upper end parts of the left and right second support frames 323.

[0028] A plate-shaped first fixing part 326a protruding to the right is formed at the upper end part of the right first support frame 321, and a plate-shaped second fixing part 326b protruding to the left is formed at the upper end part of the left first support frame 321. That is, the loading platform 32 includes a first fixing part 326a located at the right end which is one end in the left and right directions of the first support frame 321, and a second fixing part 326b located at the left end which is the other end in the left and right directions of the first support frame 321. The first fixing part 326a and the second fixing part 326b are formed of a magnetic material such as a steel plate.

[0029] The first loading platform 322 extends forward from the first support frame 321 above the lifting frame 31 and is configured as a fork-shaped loading platform. The second loading platform 324 extends forward from the second support frame 323 below the first loading platform 322. The second loading platform 324 is formed in a plate shape and has hook holes 324a at the left and right ends of the front end portion. The first loading platform 322 and the second loading platform 324 are each capable of placing luggage on them.

[0030] In the load receiving portion 3, there is a space S surrounded by the lifting frame 31, the first support frame 321 of the loading platform 32, the first loading platform 322, and the second support frame 323. The space S is open at the bottom.

[0031] Examples of the luggage placed on the first loading platform 322 and the second loading platform 324 include gaming machines such as pachinko machines and pachislot machines. Since gaming machines such as pachinko machines and pachislot machines are heavy objects, by using the lifting device 1 for transportation, it is possible to reduce the labor required for transporting the gaming machines.

[0032] The lifting device 5 includes a hydraulic base 51, a hydraulic cylinder 52, a sprocket 53, a chain 54, an operation pedal 55, and an operation lever 56. The hydraulic base 51 is provided on the connecting frame 212 and houses a switching valve for switching the oil supply direction to the hydraulic cylinder 52, a hydraulic pump for pumping hydraulic oil, and the like.

[0033] The hydraulic cylinder 52 is erected on the upper surface of the hydraulic base 51 and has a piston rod 52a that can be extended and retracted. The sprocket 53 is attached to the upper end portion of the piston rod 52a, and the chain 54 is strung around the sprocket 53. One end portion of the chain 54 is connected to the intermediate frame 243 of the mast frame 24, and the other end portion of the chain 54 is connected to the support portion 311 of the lifting frame 31 of the load receiving portion 3. The operation pedal 55 is supported at the lower end portion of the hydraulic cylinder 52, and the operation lever 56 is supported by the hydraulic base 51.

[0034] In the lifting device 5, by operating the operation pedal 55 to rotate it up and down, the hydraulic pump in the hydraulic base 51 is activated, and the pressurized oil is sent to the hydraulic cylinder 52, causing the piston rod 52a to extend. When the piston rod 52a extends, the chain 54 stretched over the sprocket 53 is pulled upward, and the load receiving part 3 connected to the chain 54 rises.

[0035] Also, when the operation lever 56 is operated to the lowering side to switch the switching valve in the hydraulic base 51, the hydraulic oil in the hydraulic cylinder 52 is sent to the hydraulic oil tank in the hydraulic cylinder 52, and the piston rod 52a contracts. When the piston rod 52a contracts, the load receiving part 3 descends together with the chain 54.

[0036] The load tightening reel 6 is attached to the mast frame 24 and has a case 61, a belt 62, and a hook 63. The case 61 can be attached to the first fixing part 326a or the second fixing part 326b of the mast frame 24, and in this embodiment, it is attached to the first fixing part 326a. The belt 62 is housed in a wound state in the case 61 and is biased in the winding direction by a biasing member such as a spring in the case 61.

[0037] As shown in FIG. 4, the tip 62a of the belt 62 is exposed to the outside from the upper end of the case 61, and a hook 63 is attached to the tip 62a of the belt 62. The belt 62 can be pulled out from the case 61 against the biasing force of the biasing member. The hook 63 can be locked to the hook hole 324a of the second loading platform 324. Also, the hook 63 can be locked to the hook fitting 325 of the loading platform 32.

[0038] As shown in FIG. 5, for example, with a load L placed on the second loading platform 324 of the loading platform 32, the belt 62 is pulled out from the load tightening reel 6 attached to the first fixing part 326a, the belt 62 is hung on the load L, and then the hook 63 is locked to the hook hole 324a of the second loading platform 324, so that the load L placed on the second loading platform 324 can be tightened by the belt 62.

[0039] Similarly, when the load L is placed on the first loading platform 322 of the loading platform 32, the hook 63 of the belt 62 pulled out from the load tightening reel 6 attached to the first fixing portion 326a is locked to the hook hole 324a of the second loading platform 324, thereby enabling the load L to be tightened.

[0040] Also, as shown in FIG. 6, with the load L placed on the first loading platform 322 and the second loading platform 324 of the loading platform 32, the belt 62 is pulled out from the load tightening reel 6 attached to the first fixing portion 326a, the belt 62 is placed over the load L, and then the hook 63 is locked to the hook hole 324a of the second loading platform 324, thereby enabling the load L placed on the first fixing portion 326a and the load L placed on the second loading platform 324 to be tightened by the belt 62.

[0041] In the lifting device 1, as in the present embodiment, when tightening the load L placed on the loading platform 32 (the load L placed on the first loading platform 322, the load L placed on the second loading platform 324, or the load L placed on both the first loading platform 322 and the second loading platform 324; the same applies hereinafter), the hook 63 of the belt 62 pulled out from the load tightening reel 6 attached to the first fixing portion 326a on the right side can be locked to the hook hole 324a on the left side of the second loading platform 324. Also, when tightening the load L placed on the loading platform 32, the hook 63 of the belt 62 pulled out from the load tightening reel 6 attached to the first fixing portion 326a on the right side can be locked to the hook hole 324a on the right side of the second loading platform 324.

[0042] Furthermore, when tightening the load L placed on the loading platform 32, the hook 63 of the belt 62 pulled out from the load tightening reel 6 attached to the second fixing portion 326b on the left side can be locked to the hook hole 324a on the right side of the second loading platform 324. Also, when tightening the load L placed on the loading platform 32, the hook 63 of the belt 62 pulled out from the load tightening reel 6 attached to the second fixing portion 326b on the left side can be locked to the hook hole 324a on the left side of the second loading platform 324.

[0043] In the lift device 1, the clamping reel 6 can be attached to both the first fixing portion 326a and the second fixing portion 326b. In this case, for example, the hook 63 of the belt 62 pulled out from the clamping reel 6 attached to the right - hand first fixing portion 326a is locked to the left - hand hook hole 324a in the second loading platform 324, and the hook 63 of the belt 62 pulled out from the clamping reel 6 attached to the left - hand second fixing portion 326b is locked to the right - hand hook hole 324a in the second loading platform 324, so that the load L placed on the loading platform 32 can be clamped.

[0044] Furthermore, the hook 63 of the belt 62 pulled out from the clamping reel 6 attached to the right - hand first fixing portion 326a is locked to the right - hand hook hole 324a in the second loading platform 324, and the hook 63 of the belt 62 pulled out from the clamping reel 6 attached to the left - hand second fixing portion 326b is locked to the left - hand hook hole 324a in the second loading platform 324, so that the load L placed on the loading platform 32 can be clamped.

[0045] Also, in the lift device 1, when the load L is placed on the first loading platform 322, the load L can be clamped by locking the hook 63 of the belt 62 pulled out from the clamping reel 6 attached to the first fixing portion 326a or the second fixing portion 326b to the hook fitting 325 of the loading platform 32. In this case, the combination of the left - right positions when attaching the clamping reel 6 to the first fixing portion 326a or the second fixing portion 326b and the left - right positions when locking the hook 63 to the hook fitting 325 can be any combination.

[0046] As shown in Fig. 4(a), a lock lever 64, a tightening handle 65, and a release button 66 are arranged on one surface 61A of the case 61. By operating the lock lever 64, it is possible to fix the pulled-out state of the belt 62 pulled out from the case 61. By operating the tightening handle 65, it is possible to wind back the pulled-out belt 62 according to the operation amount of the tightening handle 65. By operating the release button 66, the locked state of the belt 62 with the pulled-out position fixed can be released, and the belt 62 can be pulled out and wound back.

[0047] When tightening the load L placed on the loading platform 32, for example, after pulling out the belt 62 from the tightening reel 6 and locking the hook 63 to the hook hole 324a, the lock lever 64 is operated to fix the pulled-out state of the belt 62. Thereby, the tightened state of the load L placed on the loading platform 32 by the belt 62 can be maintained. Further, after fixing the pulled-out state of the belt 62 by the lock lever 64, the belt 62 can be tightened by operating the tightening handle 65, and the tightening degree of the load L can be increased.

[0048] Furthermore, when loading and unloading the load L tightened by the belt 62 from the lifting device 1, after operating the release button 66 to release the locked state of the belt 62, by removing the hook 63 of the belt 62 from the hook hole 324a or the like, the belt 62 can be automatically wound back into the case 61 by the biasing force of the biasing member.

[0049] In this way, in the lifting device 1, the luggage L placed on the loading platform 32 can be tightened by pulling out the belt 62 from the tightening reel 6 and locking the hook 63 to the hook hole 324a or the like. However, since the belt 62 pulled out from the tightening reel 6 is biased in the winding direction by the biasing member, it is possible to prevent the pulled-out belt 62 stretched across the luggage L from loosening. Therefore, the operation of tightening the luggage L placed on the loading platform 32 can be easily performed by a single operator, for example, while holding the placed luggage L with one hand and pulling out the belt 62 from the tightening reel 6 with the other hand and locking it to the hook hole 324a or the like.

[0050] As shown in FIG. 4(b), a magnet 67 is attached to the other surface 61B of the case 61 opposite to the one surface 61A. On the other hand, the first fixing portion 326a and the second fixing portion 326b of the mast frame 24 are formed of a magnetic material, and the tightening reel 6 can be detachably attached to the first fixing portion 326a or the second fixing portion 326b by the magnet 67. Therefore, when the operator performs the operation of tightening the luggage L placed on the loading platform 32, the operator can appropriately select the attachment position of the tightening reel 6 from the first fixing portion 326a and the second fixing portion 326b according to the ease of operation and the working environment such as the working space, and the tightening operation can be facilitated.

[0051] As shown in FIG. 7, when the lifting device 1 is used, for example, when installing the lifting device 1 with the luggage L being a gaming machine placed on the loading platform 32 on the installation shelf 71 of the pedestal island 7 provided in the game hall, after moving the lifting device 1 with the luggage L placed on the loading platform 32 to the front of the pedestal island 7, the luggage L is lifted from the loading platform 32 and installed on the installation shelf 71 of the pedestal island 7.

[0052] In the game hall, the chair 8 is often fixed to the floor surface in front of the pedestal island 7. However, even if there is a chair 8 fixed to the floor surface in front of the pedestal island 7, since the lifting device 1 has the space S in the load receiving portion 3, when moving the lifting device 1 to the front of the pedestal island 7, by positioning the backrest 81 of the chair 8 in the space S, it is possible to prevent the load receiving portion 3 of the lifting device 1 from interfering with the chair 8.

[0053] Therefore, the luggage L placed on the loading platform 32 of the lift device 1 can be transported to a location very close to the pedestal island 7 which is the destination, and it becomes possible to easily carry the luggage L from the loading platform 32 into the installation shelf 71 of the pedestal island 7 and install it. Thereby, the labor required for the installation work of the luggage L on the installation shelf 71 can be reduced. In particular, when the luggage L is a heavy gaming machine, it is possible to effectively reduce the labor.
