Description

[Detailed description of the invention] [Industrial application field] This invention allows objects and equipment, such as display stands and conference desks, which are normally installed in fixed positions, to be moved to different positions by rearranging or otherwise. This invention relates to a trolley jig for moving object equipment used when it is necessary to move objects.

[Problems to be solved by prior art and ideas]

Not limited to the above-mentioned conference desks, physical equipment that is normally installed and used in a fixed position is not usually equipped with casters as a means of movement.
Therefore, when relocating or moving equipment, it is necessary to lift and move it manually, but such equipment is often long and heavy, and moving it requires great physical effort. You will be forced to do so. Therefore, moving carts equipped with special jacking means have been considered in the past, but these are all large and expensive, and depending on the object equipment, the distance between the bottom surface of the object equipment and the floor surface, that is, the distance between the bottom surface of the object equipment and the floor, Since there are large variations in the insertion intervals, there is a problem in that a single moving trolley cannot cover the movement of a wide variety of objects and equipment.
For example, in a device that uses a toggle link mechanism to levitate object equipment from the floor and move it, the amount of lift (levitation amount) of the object equipment by the toggle link is determined to be approximately constant. If the interval is too large or too small, it cannot be handled.

In view of the above points, it is an object of the present invention to provide a trolley jig for moving object equipment that has a compact structure, can be manufactured at low cost, and can be applied to moving a wide variety of object equipment.

[Means for solving problems]

In this invention, the upper and lower ends of the connecting rod are screwed together by a reverse screw connection to an upper pedestal on which a magnet is mounted so that its flat attraction surface is exposed on the upper surface, and a lower pedestal that holds a wheel. In addition to connecting the upper and lower pedestals, the connecting rod is provided with a rod rotation operation lever, the lower pedestal is provided with a pedestal fixing operation lever, and the magnetic attraction surface attracts and supports the lower surface of the object equipment to be moved. Features a jig for moving equipment.

[Effect]

According to the present invention, the object equipment moving jig is inserted into the four corners of the object equipment to be moved, the lower surface of the object equipment is attracted by the magnet, and the connecting rod is rotated with the wheels in contact with the floor. By raising the object equipment from the floor surface, the object equipment can be easily moved.

To adjust the height of the object equipment moving jig, the upper pedestal is fixed to the object equipment by the attraction force of the magnet, so grasp the pedestal fixing operation lever and rotate the rod from the lower pedestal fixed state. When the connecting rod is rotated by the operation lever, since the connecting rod is threadedly connected to the upper and lower pedestals by reverse screw connection, this can be done by relatively raising and lowering the upper and lower pedestals.

Furthermore, if the gap between the lower surface of the object equipment and the floor surface varies greatly depending on the object equipment, this variation can be dealt with by replacing the connecting rod with a different length.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

As shown in the drawing, the trolley jig for moving objects and equipment is
Upper pedestal 2 with magnet 1 attached, lower pedestal 4 holding wheel 3, and connecting rod 5 connecting both pedestals.
, a lever 6 for rotating the connecting rod, and a lever 7 for fixing the lower pedestal.

Furthermore, the upper pedestal 2 has a vertical screw hole 8 in the center.
The sleeve 9 has a sleeve 9, and a dish-shaped receiving plate 10 is welded and fixed to the outer periphery of the sleeve 9. The donut ring-shaped magnet 1 is wound inside the receiving plate 10, and is screwed onto the magnet 1 from below through the receiving plate 10. It is fixed with bolts 12. Reference numeral 13 in FIGS. 1 and 3 indicates a screw hole for the bolt 12. Further, when the magnet 1 is in the fixed state, the flat upper attracting surface 14 is slightly projected above the receiving plate 10, as is particularly clear from FIG. The magnet 1 is not limited to an integral donut ring as shown in the figure, but may be divided into a plurality of parts and fixed individually.

The lower surface of the lower pedestal 4 is recessed upward, and a holder 15 made of synthetic resin such as nylon is fitted into the recessed part 11, and a ball-shaped wheel 3 is fitted into the holder 15. This prevents the wheel 3 from falling off. Therefore, the presser cover 16 is fixed to the catch seat 15 with bolts 17. Further, the lower pedestal 4 has a pedestal fixing operation lever 7 removably attached to a screw hole 18 in a part of the side surface. Furthermore, a vertical screw hole 19 facing the screw hole 8 of the upper pedestal 2 is provided on the upper surface of the lower pedestal 4. In this case, male screw holes 8 and 1
9 has a reverse thread structure so that if one is a right-handed thread, the other is a left-handed thread.

The connecting rod 5 is provided with male threaded portions 20 and 21 having a reverse thread structure that fit into the screw holes 8 and 19 on the upper and lower sides,
By screwing these into the screw holes 8 and 19, the upper and lower pedestals 2 and 4 are connected. Further, a horizontal threaded hole 22 is provided between the upper and lower male threaded portions 20 and 21 of the connecting rod 6, and the lever 6 for operating the rod rotation is removably attached to this hole.

The total height of the trolley device configured in this way is
After adjusting the distance between the object equipment to be moved and the floor surface, insert it under the object equipment A as shown in Fig. 3, attract the lower surface of the object equipment with the magnet 1, and place the wheels 3 on the floor surface B. Ground it. Upper pedestal 2
is fixed to object equipment A by the above adsorption, so
The operator holds the lever 7 for fixing the pedestal with one hand to fix the lower pedestal 4, and then rotates the connecting rod 5 using the lever 6 for rotating the rod with the other hand. As a result, the upper and lower pedestals 2 and 4 move in a direction in which the upper and lower pedestals 2 and 4 are relatively separated due to the above-mentioned reverse screw structure, that is, the upper pedestal 2 rises and the object equipment A is floated from the floor surface B. This allows wheel 3
The object equipment A can be easily moved using the .

When the object equipment A has been moved to the desired location, the object equipment A is placed on the floor B by the reverse procedure to the above, and the trolley equipment is removed.

In addition, depending on the object equipment, the object equipment A and the floor B
There may be situations where the distance between the two rods is too large or too small and the total height adjustment of the trolley jig cannot be applied by rotating the connecting rod 5, but if you prepare a number of connecting rods 5 of different lengths in advance, The above situation can be dealt with by replacing the connecting rod 5.

In the example drawings, a ball is used for the wheel 3, but
Of course, other wheel structures may be used.

[Effect of idea]

As detailed above, the present invention has a simple structure mainly consisting of an upper pedestal with a magnet and a lower pedestal with wheels connected by a connecting rod, so it can be manufactured compactly and at low cost. It is possible and has high practical value.

In addition, the total height of the trolley jig can be easily adjusted by rotating the connecting rod by operating a lever, and the object equipment can be easily raised and lowered from the floor.

Furthermore, since the upper and lower pedestals are connected by a connecting rod, by using connecting rods of different lengths, it can be used even when the distance between the object equipment and the floor varies greatly, and it can be used with a wide variety of products. It is useful because it can move objects and equipment.
