[Figure 3]10 is a diagram showing the state in which the enclosure member of the transport pushcart according to the embodiment is folded. FIG. [Figure 4] 1 is a diagram showing an outline of the vicinity of a holding portion of an enclosing member of a transport pushcart according to an embodiment. FIG. BEST MODE FOR CARRYING OUT THE INVENTION

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the specific examples described in the following embodiments.

[0017] FIG. 1 is a diagram showing an outline of a transport cart (hereinafter referred to as "the cart") 1 according to this embodiment, and FIG. 2 is a diagram showing an outline of an enclosing member 5 of the cart 1. As shown in FIG.

[0018] As shown in these figures, the present handcart 1 has wheel members 2, frame members 3 that support the wheel members 2, bed members 4 that are supported by the frame members 3, and an enclosure member 5 that is detachably supported on the bed member 4. With the above configuration, the present handcart 1 allows for an increase in vertical load capacity and stable transport of cargo by making the enclosure member 5 detachable as needed, which has the effect of improving work efficiency and convenience. Details will become clear from the following explanation.

[0019] As described above, the present wheelbarrow 1 has wheel members 2. The wheel members 2 are the main members for moving the present wheelbarrow 1, and depending on the work environment, it can have a single-wheel structure with one wheel member 2 or a multiple-wheel structure with two or more wheel members 2.

[0020] Furthermore, the present wheelbarrow 1 has frame members 3 that support the wheel members 2 as described above. The frame members 3 are capable of supporting the wheel members 2 as described above, and are also capable of supporting the carrier member 4. In other words, the frame members 3 literally function as frame members that make up the entire present wheelbarrow.

[0021] Furthermore, the frame member 3 of the present handcart 1 is provided with the wheel member 2, more specifically, bearing portions 31 that hold the axles 21 of the wheel members 2. This makes it possible to rotate the wheel members 2 by pushing the frame member 3, thereby transporting luggage.

[0022] The frame member 3 of the present handcart 1 is also provided with a handle 32 that is gripped by the user. The handle 32 allows the user to apply force to the entire handcart 1, allowing the user to lift the platform member or move it back and forth or left and right.

[0023] Furthermore, the frame member 3 of the present pushcart 1 is provided with contact points 33 to prevent the pushcart 1 from tipping over if the user lets go of it. Specifically, it is preferable to provide two contact points 33 so that the frame member 3 can make contact with the wheel member 2 at at least three points.

[0024] Furthermore, the frame member 3 of the present handcart 1 is provided with a carrier support portion 34 for supporting the carrier member 4, which will be described later. By having the carrier support portion 34 support the carrier member 4, it becomes possible to carry luggage stably.

[0025] The material of the frame members 3 of the present handcart 1 is not limited as long as it is strong enough to support the platform member 4 and allow movement. However, it is preferable that the frame members 3 be made of, for example, metal or resin. More specifically, the frame members 3 of the present handcart 1 are preferably made of a high-strength, durable material to reliably support the wheel members 2 and the platform member 4. For example, steel pipes or aluminum alloy pipes are generally used to ensure sufficient rigidity. Furthermore, for applications where lightweight construction is important, carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFRP) can also be used. Furthermore, for outdoor use or use in wet environments, applying a rust-proofing treatment or weather-resistant coating to the surface can ensure long-term durability. In this way, by selecting the material of the frame members 3 according to the application, the strength, durability, and lightness of the present handcart 1 can be appropriately adjusted.

[0026] As described above, the present handcart 1 also has a loading platform member 4 supported by the frame member 3. The loading platform member 4 is configured in the shape of a container, with a bottom 41 for loading luggage and a wall 42 that covers the bottom 41, and an enclosure member 5 (described below) can be installed on the upper side, i.e., edge 421, of the wall 42.

[0027] The shape of edge 421 of platform member 4 of this handcart 1 is generally quadrangular, such as rectangular or square, but may also be circular or elliptical. Enclosure member 5, which will be described later, has multiple small pieces along each side of this shape, and by connecting these small pieces with hinges or the like, it is possible to enclose the platform member 4 in accordance with the shape of edge 421.

[0028] Furthermore, the platform member 4 of the present wheelbarrow 1 can be formed from a variety of materials depending on its intended use and usage environment, and is preferably formed from, for example, metal or resin. For example, if strength and durability are important, metals such as steel plate or aluminum alloy are preferable, while hard resins can be used if lightweight is a priority. Furthermore, if corrosion and chemical resistance are required for agricultural or horticultural use, stainless steel or weather-resistant resins are desirable. This ensures that the platform member 4 has the strength, durability, lightness, and corrosion resistance appropriate for the working environment.

[0029] As described above, the present handcart 1 also has an enclosure member 5 that is detachably supported on the loading platform member 4. The enclosure member 5 is installed along the edge 421 of the loading platform member 4 and is a member that prevents cargo from falling over when stacked vertically. In this way, the provision of the enclosure member 5 has the advantage that even if more cargo than usual is loaded on the loading platform member 4, the enclosure member 5 will stop the cargo from falling off the loading platform member 4, making it possible to load more cargo than usual.

[0030] Furthermore, the enclosure member 5 of the present handcart 1 is not limited as long as it has the above-mentioned functions, but it is preferable that it has a fence portion 51 that surrounds the edge of the loading platform member 4 and a holding portion 52 that is installed on the edge portion 41 of the loading platform member 4 to hold the fence portion 51.

[0031] As described above, the fence portion 51 of the enclosure member 5 is a component provided to prevent cargo from collapsing outward from the loading platform member 4, and constitutes the main framework of the enclosure member 5. The structure of the fence portion 51 can be configured in a shape appropriate for the work environment. For example, for agricultural or horticultural applications, the fence portion 51 may be configured in a lattice-like shape by combining thin rod-shaped materials 511, as shown in FIG. 2 above, or in a shape including an outer frame material and a mesh material stretched within the outer frame material. The mesh or lattice shape ensures breathability and prevents the load from becoming damp. On the other hand, for applications involving the handling of powder or fine particles, the fence portion 51 may be configured from plate-shaped or sheet-shaped materials to prevent small cargo from leaking out.

[0032] Furthermore, as described above, the fence portion 51 can be divided into multiple small pieces 513 that fit along each side of the edge 421 of the loading platform member 4. These small pieces can be connected to each other with connectors such as hinges or pivots, allowing the fence portion 51 to conform to the shape of the edge 421 of the loading platform member 4. For example, if the edge 421 of the loading platform member 4 is substantially rectangular, four small pieces that fit along the four sides can be provided and connected with rotatable connectors such as hinges, allowing the fence portion 51 to conform to the edge 421 and fold after being removed from the loading platform 4. Furthermore, one small piece that fits along one side of the edge 421 can be divided into multiple smaller pieces and connected with connectors. This has the advantage of making the fence portion 51 even easier to fold. An image of this configuration is shown in Figure 3.

[0033] The material of the fence portion 51 can be selected depending on the usage environment and application. For example, if strength and durability are important, it is preferable to use a metal material such as steel or aluminum alloy, while if lightweight is desired, hard resin or fiber-reinforced resin can be used. Furthermore, if use in outdoor environments such as agricultural work is envisioned, rust and deterioration can be prevented by using stainless steel or weather-resistant resin. Furthermore, wood or recycled materials may be used to reduce costs. In this way, it is desirable to select a material for the fence portion 51 so that it has the strength, durability, lightness, and corrosion resistance appropriate for the work environment and application.

[0034] Furthermore, different materials can be combined for the rods 511 and mesh materials that make up the fence section 51. For example, by forming the outer frame from metal pipes and using a resin net for the inner mesh material, it is possible to achieve both rigidity and light weight. This type of composite structure improves the balance between durability and workability.

[0035] Additionally, the lower part of the fence section 51 of the enclosing member 5 of this handcart 1 has a holding section 52 that is attached to the edge 421 of the loading platform member 4 to hold the fence section 51. Figure 4 shows an example of the holding section 52. This makes it detachable from existing handcarts, increasing the expandability of its uses.

[0036] The structure of the holding portion 52 is not particularly limited, but it may be, for example, a recessed member having a recess that simply contacts the edge 421 of the loading platform member 4 to prevent slippage, or may be provided with a U-shaped or L-shaped locking piece that matches the shape of the edge 421 to stably hold the fence portion 51. Furthermore, by providing a viscoelastic material inside the recessed member, it is possible to prevent loosening due to vibration or impact and ensure quietness.

[0037] Furthermore, as shown in this figure, the holding portion 52 may have a structure with an insertion groove that fits into the edge portion 421, in which case the enclosing member 5 can be easily attached by simply pushing it in from above. The insertion groove has a cross-sectional shape that follows the outer shape of the edge portion 421 of the loading platform member 4, allowing for secure engagement.

[0038] Furthermore, the holding portion 52 may be fixed to the edge portion 421 by fastening members such as bolts and nuts, pins, clamps, etc. Such a structure allows for strong fixing, ensuring stability even when carrying heavy loads or in a work environment with high vibrations.

[0039] In this way, the specific shape of the holding portion 52 can be selected appropriately depending on the work environment and purpose of use, and it is desirable for the structure to be such that the enclosing member 5 is securely fixed while allowing it to be easily attached, detached, and folded.

[0040] In this case, the holding portion 52 may be fixed to the fence portion 51, or may be configured to be rotatable. Configuring the holding portion 52 to be rotatable has the advantage that it is easy to fix the holding portion 52 to the loading platform 421 even if the orientation of the small pieces of the fence portion 51 is slightly misaligned.

[0041] As described above, the present invention provides a transport cart that can transport more loads in the vertical direction and an enclosure member used therewith. [Industrial Applicability]
