BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier for placing and carrying an object to be carried, and more particularly to a carrier that can be folded when not in use.

[0002]

2. Description of the Related Art As a carrier for carrying an electrocardiograph or the like and carrying it near a subject, many foldable devices have been known.

[0003]

However, the conventional foldable carrier has a large number of parts, has a complicated structure, and is expensive.

The present invention has been made in view of the above points, and an object thereof is to provide a foldable carrier having a simple structure with a small number of parts.

[0005]

In order to achieve the above object, the present invention has a platform for placing an object to be transported on the upper and lower sides, respectively, and a carrier which is foldable in the left-right direction is rotated relative to each other. A pair of left and right struts that are connected to each other as much as possible, wheels attached to the lower ends of the stanchions, and one end rotatably supported above the pair of left and right struts,
It has a connecting part between the other ends and can rotate with each other through this connecting part.
Pair and the upper base of which is coupled to the ability, the connecting rod a pair of connecting respectively between the bottom of the right and left two pairs of struts, Shimodai Prefecture that one at one end of the connecting rod is supported rotatably A drive shaft for connecting the vicinity of the other end of the lower base and the connecting portion of the upper base,
When the upper end of the drive shaft is fixed to the connecting portion of the pair of upper bases,
Both have a fastening member for fixing the pair of upper bases to each other .

[0006]

In the carrier constructed as described above, 1
The upper base is folded by rotating and bringing the pair of support columns closer to each other, and at the same time, the lower platform is pulled upward through the drive shaft to approach the position along the support columns. At this time, since the pair of upper bases are connected by the upper end of the drive shaft, the number of parts can be reduced. Moreover, since the upper end of the drive shaft can be fixed to the connecting portion of the upper table by the fastening member, the carrier can be kept in a state of being used or folded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the carrier of the present invention will be described below with reference to the drawings.

1 to 3 show the configuration of an embodiment of the present invention. In these figures, of the pair of left and right columns 2 and 3, which are arranged in an X shape and whose longitudinal center is rotatably connected by a support shaft 1, one column 2 has an upper end by a handle 4. They are connected together. In addition, casters 5, which are wheels, are attached to the lower ends of the columns 2 and 3,
The vicinity of the lower ends of the pair of left and right columns 2, 3 are connected by connecting rods 6, 7 fixed in the right-angled direction.

Near the upper ends of the columns 2 and the upper ends of the columns 3, both ends of a pair of left and right upper pedestals 8 and 9 are rotatably supported via shafts 10 and 11, respectively. Further, connecting portions 12 and 13 are provided on both sides of the other ends of the pair of left and right upper bases 8 and 9, respectively, and are rotatably connected via an upper end of a drive shaft 14 which will be described later. Further, hooks 16 provided on both upper sides of one end of the lower table 15 are rotatably engaged with the connecting rod 7. Furthermore, the lower end of the drive shaft 14 is rotatably engaged with hook portions 17 provided on both upper sides near the other end of the lower table 15. When the columns 2 and 3 are opened and the upper bases 8 and 9 are in the horizontal position, the lower base 15 is also horizontal via the drive shaft 14. In this state, substantially inverted U-shaped hook portions 18 provided on both upper sides of the other end of the lower base 15 engage with the connecting rod 6.

On the other hand, the upper ends of the pair of drive shafts 14 are bent outward at a right angle, and the connecting portions 1 of the upper bases 8 and 9 are respectively connected.
It penetrates 2 and 13. An outer diameter screw is formed on the bent tip of the drive shaft 14, and a nut 19 as a fastening member is screwed on. Then, by tightening the nut 19, the connecting portions 12 and 13 are integrally fixed. Reference numeral 20 is a brake provided on the caster 5.

Next, the operation of this embodiment will be described. Stanchions 2,
3 is opened to bring the opposite surfaces of the upper bases 8 and 9 into contact with each other,
When 9 is made horizontal, the lower table 15 is also pushed down via the drive shaft 14 and becomes horizontal. At this time, this state can be firmly held by tightening the nut 19.
On the contrary, when the nuts 19 are loosened and the columns 2 and 3 are closed, the connecting portions 12 and 13 are pushed upward, and the lower table 15 is also rotated around the connecting rod 7 via the drive shaft 14 and pulled upward. And is close to the position along the column 3. Nut 19 at this time
This state is maintained by tightening.

According to this embodiment, since the pair of upper bases 8 and 9 are connected by the upper end of the drive shaft 14, the number of parts can be reduced and the structure can be simplified. Also, using the upper end of the drive shaft 14, a nut 19 is used to connect the upper bases 8 and 9 to each other.
2,13 can be fixed, and the carrier can maintain the condition when used or folded.

In the above embodiment, the case where the lower table 15 is hung below the connecting rods 6 and 7 has been described, but the lower table 15 may be locked onto the connecting rods 6 and 7.

[0014]

[Effect of the Invention] According to the present invention, the number of parts is reduced.
It has a simple and simple structure, and is used and folded.
A foldable carrier that can be easily and firmly held
Can be realized.
