Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is used for loading and unloading heavy loads such as high-pressure gas cylinders, case boxes filled with heavy items, and baggage, and transporting loads from a predetermined location to a desired location. It is related to the safety cover of the carrier.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, heavy loads such as high-pressure gas cylinders, case boxes filled with heavy items, and baggages that cannot be used by a forklift are manually loaded and unloaded, so it is extremely labor-intensive and dangerous. It was a lot of work.

The inventor has developed a wheeled carrier that solves the above problems, and a carrier that separates the carrier into a baggage stacking device and a moving car body, and has already developed Japanese Patent Application No. 3-98988 or Japanese Patent Application No. 98988. We have filed many patent applications including the patent application of No. 3-279917.

As a result of many field tests, the inventor subsequently supported the luggage with the luggage support frame, released the lock mechanism, and pushed up to the place where the luggage was desired to be loaded by using the energy of the pressing mechanism. It was discovered that a part of the body could get inside the machine frame and could be caught in the luggage support frame, resulting in personal injury.

[0005]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

[0006] Wheels 3 are provided on the left and right sides of the lower portion of a moving vehicle frame 2 provided with a push handle 1 projecting on the moving vehicle frame 2, and a support frame 4 is superposed on the moving vehicle frame 2 and an upper portion 4'is pivotally attached to a lower portion 4 ". It is movably provided up and down, and a luggage support frame 5 for supporting luggage a is slidably provided on the upper surface of the support machine frame 4, and a lock mechanism 6 is provided between the support machine frame 4 and the luggage support frame 5. A transport machine provided with a push-up mechanism 7 that pushes the luggage support frame 5 upward when the locking mechanism 6 is released, and the opening of the upper and lower surfaces of the support machine frame 4 is covered by a safety cover 8. The present invention relates to a transporter characterized by the above.

Further, a luggage support frame 11 for supporting the luggage a is slidably provided on the upper surface of the machine frame 10, a lock mechanism 12 is provided between the machine frame 10 and the luggage support frame 11, and the lock mechanism 12 is released.

[Action]

 The operation of claim 1 will be described.

The luggage a is manually placed on the lower portion of the luggage support frame 5, the hand handle 1 is lifted upward, and the moving vehicle frame 2 is diagonally laid between the loading location and the ground. When the lower part 4 "is lifted and held at a height substantially horizontal to the height of the loading place with the axis of 'and the locking mechanism 6 is released, the luggage support frame 5 is lifted by the push-up mechanism 7 while the luggage a is placed. Since the upper surface of the carrier frame 4 is slid and pushed to the loading place, the pushing force is used to push the load a by the force of the arm to load the load a to a desired place.

At this time, since the safety cover 8 is attached to the opening on the upper surface of the lower surface of the bearing frame 4 to cover the opening, the safety cover 8 interferes with the opening of the frame 4 of the bearing body. Part of this is blocked.

The operation of claim 2 will be described.

[0012] When the machine frame 10 is slanted between the loading place and the ground, and the luggage a is manually placed on the lower part of the luggage support frame 11 to release the lock mechanism 12, the luggage support frame 11 pushes up the lifting mechanism 13 Because the upper surface of the machine frame 10 is moved upward by the pushing force of the load a, the load a is pushed up by the force of the arm while using the pushing force of the upward movement to load the load a to a desired place. .

At this time, since the safety cover 8 is attached to the opening on the upper surface of the lower surface of the machine frame 10 as described above, it is possible to prevent a part of the body from entering the opening.

The U-shaped locking hooks 58, 58 are provided on the rear surface of the lower surface of the vertical rods 40, 40 of the machine frame 10 in a protruding manner, and the locking horizontal rods 59 that engage with the locking hooks 58, 58 are provided. The moving body B is installed on the lower portion of the vehicle frame 60, and locking rings 61, 61 for restricting the left and right positions of the moving body B with respect to the load lifting and lowering device A are attached to the locking horizontal rod 59. When the horizontal rod 59 of the moving body B is locked to the locking hooks 58 and 58, and the lower surface of the load lifting and lowering device A and the upper surface of the moving body B are overlapped with each other, the upper cross rail of the load lifting and lowering device A is overlapped. The locking male piece 62 projecting from the back side of the central portion of the lower surface of 42 is fitted into the engagement receiving body 64 provided on the upper horizontal rod 63 of the vehicle frame 60 of the moving body B, and the luggage is pushed up and down by the T-shaped locking rod 65. The device A and the moving vehicle body B are fixed as one body.

Since the embodiment of claim 2 is configured as described above, it has the following operational effects.

The machine frame 10 of the load lifting and lowering device A is slanted by the grounding portion 20 and the locking portion 21 to the ground and the place where the luggage is desired to be carried up, and the luggage a is manually placed on the cargo receiving plate 27 and locked. When the foot pedal 51 ′ of the mechanism 12 is stepped on, the linking mechanism causes the locking rod 54 of the luggage support frame 11 to disengage from the hook portion 49 ′ of the hook body 49 and is compressed inside the cylinder of the gas spring 28. The piston rod 28 'extends due to the gas pressure of the gas, and the luggage support frame 11 slides on the machine frame 10 while supporting the luggage a while using the guide frame 41 of the machine frame 10 as a guide, and at the top of the machine frame 10. Since it moves upward, the operator manually pushes the load a and pushes the load a to the loading place while utilizing the inertia of the upward movement.

At this time, since the concealing body 8 is attached to the opening of the machine frame 10, the risk of a part of the body being caught when the luggage support frame 11 is moved up and down is prevented.

Reference numeral 57 is a roller.

In the present invention, as described above, the concealing body 8 is attached to the opening of the supporting machine frame 4 or the machine frame 10 so that the opposite side can be seen through. However, the concealing body 8 may be made of a net (made of metal or synthetic fiber. ) Or a perforated plate (punching metal or expander metal) or a transparent plate such as a resin plate that can be seen through and the rigidity of the concealing body 8 can prevent accidental insertion of the hand. Partly if you can insert your hand by mistake and the lock mechanisms 6 and 12 come off at that time, and you can secure safety so that you do not get injured by pinching your hand due to the upward movement of the luggage support frames 5 and 11. It can be something like this. At this time, it is inconvenient for the work if the other side cannot be seen through.

[Effect of device]

 In the present invention, since the concealment body is attached to the opening of the moving vehicle frame or the machine frame as described above, the luggage is supported by the luggage support frame, the lock mechanism is released, and the energy of the lifting mechanism is pushed to the place where the luggage is desired to be carried. When you push it up by using the, the concealing body prevents part of the body, especially the hand, from getting caught in the bearing frame and the opening of the frame, preventing personal injury and ensuring safe, convenient and practical baggage lifting. It becomes a unloading carrier.
