Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an improvement of a handle-removable transport platform in which the handle can be attached and detached from the transport platform.

[Conventional technology]

Conventionally, this type of transport platform with a detachable handle is
For example, a structure in which a handle is attached to a transport platform via a folding device, or a structure in which a hole is made in the surface of the transport platform and the lower end shaft of the inverted U-shaped handle is inserted into the hole to be attached or removed. etc. are known. However, in the former case, since the handle cannot be removed, even if the handle is no longer needed while loaded with articles, a space for the handle is required, making it impossible to save space. Also, in the latter case, it is necessary to make a hole that passes vertically near the edge of the transport platform, and the handle attachment position is installed inside the transport platform during transportation, which results in a narrow loading area for the goods. Become. Furthermore, since the attachment/detachment hole opens upward when not in use, it has the disadvantage that it is easily clogged with dirt and the like. Furthermore, the mounting surface of the pedestal of the carrier must be formed in advance, making it impossible to reduce costs.

[Problem that the invention attempts to solve]

This idea was devised as a result of intensive research in view of the above circumstances, and its main challenges were to make it possible to use the entire surface area of the carrier as a loading area for goods, and to move the handle freely in each direction. To provide a transport stand with a detachable handle and a simplified structure of the base.

[Means to solve the problem]

In order to solve the above problems, this invention provides a handle removable carrier in which the handle is detachably attached to the carrier, (a) a connecting part is provided at the lower end of the handle that protrudes outward approximately horizontally; b) A connecting bracket is provided in the center of the outer frame of the pedestal of the transport platform, and is fixed to the outer frame of the pedestal by extending crosswise on the same horizontal plane, so that the tip of the connecting bracket does not protrude beyond the side edge of the carrier. (c) The connection between the connecting portion and the connecting holder is made of a combination of a square shaft and a square tube into which the square shaft is fitted. We are taking technical measures.

[Effect]

In this design, the connecting part of the handle and the connecting bracket provided on the underside of the carriage are attached and detached by a combination of a square shaft and a square tube. The handle can be attached to the carrier by pushing it into the tool from the outside. Further, the handle can be removed by pulling the connecting portion of the handle in the pulling direction. Since the connection holders are arranged at approximately 90 degree intervals, the connection part can be pushed into the connection holder at an appropriate position depending on the direction of transportation, and the handle can be attached for transportation. Furthermore, since the connecting bracket is located below the carrier and does not protrude beyond the side edges, the entire surface of the carrier can be used for loading goods. Furthermore, since the connecting bracket is spanned across the center of the outer frame of the pedestal so as to form a cross, it can be used as a frame for placing articles on the pedestal or for reinforcing the pedestal.

【Example】

Hereinafter, a preferred embodiment of the handle detachable transport platform of this invention will be described based on the drawings from FIG. 1 onwards. This handle-removable transport platform 1 consists of a handle 2 having a single connecting portion 3 at the lower end, and a transport platform 4 having connecting holders 5 on all sides corresponding to the connecting portion 3. That is, the handle 2 has a base frame pipe 20 whose upper part is tilted back, and a gripping rod 21 extending left and right at its upper end, and a square shaft-shaped connecting part 3 that projects horizontally from the front lower end of the base frame pipe 20 is integrated with the handle 2. It is formed. A tapered surface 3' whose width gradually becomes narrower is formed at the tip of the connecting portion 3, and serves as a guide when inserted into the connecting receiver 5. On the other hand, the transport platform 4 includes a pedestal outer frame 40 made of a rectangular metal frame formed from an angled metal material, casters 41 fixed to the four corners of the pedestal outer frame 40, and the pedestal outer frame 4.
It consists of hollow pipes 42 that are horizontally suspended in a criss-cross manner on the bottom surface of 0. In the case of this embodiment, the hollow pipe 42 is made by welding approximately half square pipes to the left and right from the center of one square pipe, and hanging them integrally so as to intersect vertically and horizontally on the same horizontal plane (level). It has been given,
The illustrated example has four connecting portions 3 formed approximately at the center of each side of the carrier 4 at 90 degree intervals. With the above structure, the handle 2 can be attached to any side of the carrier 4 by pushing the connecting portion 3 of the handle 2 into the coupling holder 5 of the carrier 4. Here, the hollow pipe 42 is not limited to a square pipe, but may have any shape as long as it is a square pipe having a polygonal cross section, and the connecting portion 3 may be made to correspond to the hollow shape. Further, even when the connecting portion 3 is used as a shaft, the shaft may be solid or hollow as long as it can be fitted into the rectangular tube of the connecting receiver. In addition, 43 in the figure is a reinforcing plate stretched at the corner of the pedestal outer frame 40. The handle 2 can be removed by pulling the connecting portion 3 from the connecting holder 5 in the pulling direction. Next, it is preferable to provide a stopper mechanism S that restrains the connection between the connection portion 3 of the handle 2 and the connection receptacle 5 of the carrier 4 when the connection portion 3 of the handle 2 is fitted into the connection receptacle 5 of the transport platform 4. In this embodiment, as shown in FIG. 4, a hook 6 that is biased outward and can be retracted is provided on the shaft end side of the connecting portion 3, and a hole 7 corresponding to the hook groove 6 is provided on the shaft end side of the connecting portion 3. A stopper mechanism is provided which is drilled at a corresponding position on the tool 5. Therefore, when the connecting portion 3 is fitted into the connecting holder 5, the hook 7 is depressed by the elastic force, and when the hook 7 is inserted to the hole 7 position, it protrudes due to the repulsive force and is aligned with the hole 7 and latched. In addition, when pulling out the connecting part 3, the hook 6 in the hole 7 is pushed in to release the latch, and the connecting part 3 can be pulled out. In the illustrated example, the hook has a spherical shape, so if it is pulled out forcefully, it will be disengaged. It goes without saying that the configuration of this stopper mechanism is not limited to the above embodiment, and other known engagement configurations may be used. Also, if the length of the connecting part 3 is set long,
The force in the pulling direction is converted into torque, making it difficult to pull out from the connection receiver 5, and it is also possible to increase the connection force. In this way, by increasing the coupling force between the coupling portion 3 and the coupling holder 5, the handle 2 can be moved in forward and backward directions to move the carrier 4 forward and backward. Incidentally, in this invention, it is not necessary to provide a stopper mechanism. In each of the above embodiments, the connecting portion 3 is a square shaft and the connecting bracket 5 is a hollow square pipe.
may be made into a square shaft, and the connecting portion 3 may be made into a hollow square pipe. In addition, the carrier 4 is not limited to a rectangular shape, but a polygonal, circular,
It may be elliptical or the like. The material may be metal, synthetic resin, wood, or other types.

[Effect of the idea]

Since this invention consists of the above structure, the handle can be attached and detached from the carrier with a simple operation, and since it uses a connection structure using a square shaft and a square tube, each part collides and falls over when engaged. There is no problem and only one connecting part is enough. Further, after loading the articles onto the transport platform, the connecting receiver in the transport direction can be selected and the connecting part of the handle can be pushed in and attached, thereby facilitating the transport work. Furthermore, since the attachment/detachment configuration of the handle is not visible on the surface of the carrier, the entire surface of the carrier can be used as an article loading surface, so articles can be loaded without any gaps. In terms of structure, the connecting bracket is provided in a cross shape with respect to the outer frame of the pedestal of the carrier and forms a horizontal surface, so the transported item can be placed directly on it, which greatly simplifies the configuration and makes it suitable for mass production. Cost reduction can be achieved. Furthermore, it is also possible to extend a plate serving as a base plate to the horizontal surface formed by the connecting holder. In addition, since the connecting bracket does not protrude outward when the handle is removed, similar types of carriers with removable handles can be lined up without gaps. Particularly, this transport platform with detachable handle can be used effectively when placed on a truck or the like with a limited installation area and used as a storage platform for storing loaded items as replenishment products.
