2. Description of the Related Art Conventionally, a transporting device as shown in FIG . 7 is lightweight in a place where vehicles such as trucks and forklifts cannot directly enter, such as open-air or indoor construction sites, factory premises, and exhibition sites for construction materials. Each piece such as an aerated concrete plate is used to transport a conveyed object such as a long tied body having a considerable weight as a result of being tied, although being lightweight. A pair of wheels is provided on both sides of a frame having a U-shaped cross section, and an elastic material such as a rubber pad is mounted or fixed on the bottom surface of the frame as needed, so that the transported object can be mounted on the upper surface thereof. In this case, the worker transports the transported object while holding one end of the transported object and maintaining a balance. The carrier is
It has the advantages of a simple shape, light weight, a small storage space for the transport tool, and easy transport by truck, etc., but the transported object is smaller than the width of the U-shaped frame.
It cannot be used for a product that is too thick or too thin, and it is difficult to maintain a balance during transportation because the object to be transported is not simply placed and fixed on the transport device, so it is shaky during transportation. There was a disadvantage that there is.

For this reason, as shown in FIG. 8 , the present applicant has filed a Japanese Patent Application No. Hei 7-132567 (see Japanese Patent Application Laid-Open No. 8-290773) and proposed a carrier which has eliminated the above-mentioned disadvantages. I just did it. This carrier is basically composed of a tray, a wheel body, an up-and-down handle body and a body to be carried, and the carrier can be assembled and disassembled. Since it is fixed, it is stable, so operability is good and effective for transporting heavy objects, but it is not suitable for transporting lighter objects to be transported and the transport equipment itself becomes considerably heavy. Had. The present invention overcomes the above disadvantages.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the wheel body 1, frame body 20, and rotating frame 2 of each component of the invention according to claims 1 to 5 will be described.
2 and the transported object fixed body 3 will be described in detail.

[Wheel body 1] This wheel body 1 is common to all the inventions according to claims 1 to 5. Specific configuration of the wheel assembly 1 is described in FIGS. 2-4. This wheel body 1
Is composed of a left wheel 10 and a right wheel 11, and a left wheel 1
0, the right wheel 11 may be a solid rubber tire having no air therein, or a hollow rubber tire having air therein. In short, it goes without saying that the wheel body may be a simple iron wheel, and all the rotating wheels that can be used for traveling can be used. However, from the viewpoint of stability, pneumatic rubber tires are most suitable for the right and left wheels 10 and 11 in terms of operability. Further, the mounting method of the wheel body 1 only requires that the carrier is rotatably mounted so as to move on the frame main body 20 in the transport direction, and the mounting method may be detachable or fixed. Alternatively, a method of detachably or fixedly attaching to the left and right of one axis may be used, or a method of detachably or fixedly attaching to different axes provided on the left and right respectively. In short, the method of attaching the left wheel 10 and the right wheel 11 to the frame main body 20 does not matter how it is attached. In this respect, as one method of attaching the frame main 20 of the wheel body 1, the frame main traveling direction freely movable carrier
A method that can be detachably attached to the lower surface of the device 20 with screws or bolts or attached by welding can be used.

[0009]

[Frame main body 20] The frame main body 20 according to the first to fifth aspects of the present invention can place at least the transferred object 4 and can mount the left wheel 10 and the right wheel 11 thereon.
Place the rotating frame 22 at a position that is not centered in the longitudinal direction.
It is at least important to have a structure that can be rotatably supported in a direction parallel to the upper surface of the frame main body 20 and that can removably mount the transferred object fixing body 3 so that the transferred object 4 can be gripped and fixed. It is. The frame body 2 according to the invention as claimed in claim 1 to claim 5, off
It is composed of a frame main body 20 and a rotating frame 22 . When the rotating frame 22 is placed on the transported object, the rotating frame 22 is set so as to be orthogonal to the axle connecting the left and right wheels.
Because it can rotate parallel to the upper surface of the over arm principal 20, FIG.
As shown in FIG. 5, in this state, the position of the center of gravity of the frame body 2 is located closer to the operator than the center of gravity of the wheel body when viewed from the operator side.
Will be that. In any case, the rotating frame 22 and the frame
Center of gravity (W
2) needs to be configured so as to come from the operator side of the carrier to the operator side from the center of gravity (W1) of the wheel body 1 ( FIG. 5,
See FIG. 6 ). To the extent that we can respond to this request,
The pivotal support position of the rotating frame 22 is set with respect to the upper surface of the tray 1.
It only has to be supported. This is because the transport tool must be stably stopped on the ground so that the transported object 4 can be easily placed on the transport tool.

The above-described state in which the ground contact end 21 of the rotating frame 22 is in contact with the ground is as shown in FIG. In the invention according to the first aspect, the position of the center of gravity of the frame body 2 is viewed from the operator side of the carrier and is determined from the center of gravity of the wheel body.
The frame ground contact end 21 abuts on the ground so as to come to the operator side, and the intersection of the line L3 passing through the axis of both wheels 10 and 11 with the upper surface of the frame ground contact end 21 and the frame body 2 A line L2 and a ground line L1 make up a triangle,
It is preferable to configure the triangle such that the longest side L1 of each side of the triangle is the ground line, and the frame body 2 is the second longest side L2. In this case, as described above, the shape of the triangle is the relationship between the first side and the second side (L1>
The length L1 between the wheel body mounting position of the frame body 2 and the frame ground abutting end 21 is determined as long as L2) is satisfactory. It goes without saying that it is restricted in consideration of the object 4.

The frame main body 2 that satisfies such conditions
As shown in FIG. 4, the configuration of No. 0 can adopt a substantially π-shaped cross section as viewed from the operator side . The method of attaching the wheel body 1 to the frame main body 20 differs depending on what kind of frame main body 20 is employed. For example, when a flat steel plate or the like is used for the frame main body 20, a method in which a freely movable carrier in the traveling direction is directly attached to the lower surface of the frame main body 20, or a frame 23 separately attached to the lower surface of the frame main body 20 is attached or detached by welding, bolts or the like. There is a method of attaching the wheel body 1 to the lower frame 23 by a method of freely mounting or the like. In any case, it is only necessary that the wheel body 1 can be detachably mounted so that the wheel body 1 can travel with respect to the frame main body 20.

Further, on the frame main body 20, transported object fixing plates 30, 31 constituting the transported object fixed body 3 are provided.
Insert from right and left as seen from the transport direction, slide,
Since it needs to be fixed, a structure that meets the demand is required. The frame body 2 according to the first aspect of the present invention.
Is rotatable parallel to the frame body 20 and its upper surface
And a rotating frame 22 pivotally supported by the rotating frame 22 . this
The pivotal support position of the rotating frame 22 is the length of the rotating frame 22.
Not at the center of the hand, but at the position deviated from the center
The main body 20 is pivotally supported. In any case, the frame owner
The upper surface of the body 20 may be any surface as long as the rotating frame 22 can rotate.

With this configuration, when the frame body 2 is stored in the vehicle, the rotating frame 22 can be substantially overlapped with the frame main body 20 by rotating the rotating frame 22, and the wheel body 1 and the frame main body 20 are integrated. Since the frame body 2 can be separated into two portions of the fixed object 3 to be conveyed, a carrier that can be compactly stored and can be easily assembled can be obtained. When the rotating frame 22 is detachably attached to the frame body 20, the rotating frame 22 can be separated from the frame body 20.
It can be conveniently separated when stored in a vehicle or the like. By doing so, it is possible to obtain an assembling-separable transport tool including the frame main body 20 having the wheel body 1, the rotating frame 22, and the transported object fixed body 3. In any case, the left and right wheels 1 constituting the wheel body 1
Needless to say, 0 and 11 can be attached to and detached from the frame main body 20 as necessary.

The engagement between the transported object fixing plates 30 and 31 and the frame main body 20 is performed when the transported object fixing plates 30 and 31 are concave or convex.
By making the 0 side convex or concave, the transported object fixing plates 30 and 31 can be attached to the frame main body 20 so as to be detachable and slidable from each other. In any case, any structure can be adopted as long as they can mesh with each other, and can slide and fix each other.

[0015]

[Conveyed object fixed body 3] The transferred object fixed body 3 is composed of a pair of transferred object fixing plates 30 and 31. As described above, the transported object fixing plates 30 and 31 each preferably have a shape like a book end, and can be inserted into and removed from the frame main body 20 in the right and left directions as viewed from the transport direction. It has a structure that can be fixed freely. Specifically, the lower ends of the transported object fixing plates 30 and 31 have a concave or convex shape so as to bite into the frame main body 20. As an example, a type having holding portions at both ends of the transported object fixing plates 30 and 31 so as to hold both ends of the frame main body 20 and a type fitting into two holding grooves provided in the frame main body 20 are exemplified. Is shown. In some cases, a single groove or a single protrusion is provided on the upper surface of the frame main body 20 so that the frame main body 20 can be held and slidably mounted on the frame main body 20 to be freely fixed. You can take any structure you can.

The transferred object fixing plates 30 and 31 have a function of gripping and fixing the transferred object 4. However, since the rotating frame 22 is provided between the transferred object 4 and the transferred object fixing plates 30 and 31. Since there is a slight gap, it cannot be fixed securely. Therefore, the transported object fixing plates 30, 31
A holding pad or the like is attached in a place so that the side surface of the rotating frame 22 does not abut on the upper side of the transferred object fixing surface,
Alternatively, by providing a cutout at the lower end of the upper side of the transported object fixing plates 30 and 31 on the side of the transported object fixing surface, the transported object 4 can be securely connected to the pair of transported object fixing plates 30 and 3.
1 can be gripped. Also, rotating frame 2
In the case of using a U-shaped section steel for 2, if the thickness is adapted to the inner width of the section steel, a little backlash occurs, but the transferred object fixed bodies 30 and 31 complement the backlash. Since the transferred object functions as a guide, the transferred object is not securely fixed, but does not hinder the transfer of the transferred object. In this way, if the transported object fixed body 3 is detachably and slidably attached to at least the frame main body 20, the transported object 4 can be transported.

Each of the transported object fixing plates 30 and 31 has a fixing screw 32, and the transported object fixing plates 30 and 31 can be fixed to the upper surface of the frame main body 20 by raising and lowering the fixing screw 32. The structure of the fixing screw may be a thumb screw type or a bolt having an eye. In any case, the transported object fixing plates 30, 3
The screws need not be screws as long as they can fix and release the frame 1 and the frame main body 20 freely.
