Description

  The present invention relates to a cart capable of carrying a load.

  Conventionally, various types of carts capable of transporting luggage have been proposed. For example, a cart (wagon) having a structure in which a shelf plate on which a load can be placed is attached to a frame made of stainless steel or plastic to which casters (wheels) are attached is known (for example, Non-Patent Document 1). reference).

  As another example, there is known a cart (wagon) having a structure in which a hook that allows a bag to be attached and detached is provided on a frame (see, for example, Non-Patent Document 2). In the configuration of Non-Patent Document 2, a bag (bucket) in which luggage can be placed can be easily removed from the cart and carried. For this reason, according to the configuration of Non-Patent Document 2, for example, in a place where it is difficult to carry luggage with a cart, it is possible to flexibly cope with removing the bag from the cart and carrying it.

Design Registration No. 1363045 “Storage bag interior BOOK”, “Happy bucket wagon 3 tiers”, [online], Rakuten, [October 16, 2012 search], Internet <URL: http://item.rakuten.co.jp/kaitekishuno / 14884521lbb3hb />

  By the way, in a nursing facility, for example, a cart is used to carry luggage (for example, shampoo, towel, trash can, etc.) to the bathroom. When used for such purposes, the types of luggage carried by carts tend to increase. In addition, for example, there are luggage such as towels before and after use, and it is desirable to carry these separately. Under such circumstances, it is expected that nursing carts and the like are desired carts that can be easily transported in a state in which luggage is sorted by type.

  In this regard, even with a wagon (cart) configured as shown in Non-Patent Documents 1 and 2, it is possible to transport the cargo to be transported in a state of being sorted by type using a storage tool such as a bag. However, in the conventional cart, the degree of freedom is not necessarily large with respect to the types and number of storage tools that can be arranged, and further, the manner in which the storage tools are arranged. For this reason, it is expected that an easier-to-use cart is desired.

  In view of the above points, an object of the present invention is a cart suitable for transporting storage devices such as bags, and provides a cart that is easy for a user to use freely according to the purpose of use and preference. That is.

  In order to achieve the above object, a cart of the present invention includes a frame portion including a pair of struts arranged in parallel to each other, a wheel that enables movement of the frame portion, and a bridge portion that bridges the pair of struts. A plurality of hooked portions that are provided at intervals in the bridging direction of the bridge portion and are capable of hooking objects (first configuration). Note that the plurality of hooked portions arranged at intervals in the bridging direction do not necessarily have to be arranged in a straight line, and may be arranged in a zigzag shape in some cases.

  The cart of this configuration is configured such that a plurality of hooked portions are provided at intervals in the bridge portion. For this reason, in the cart of this structure, it can be expected that the degree of freedom is increased with respect to the number and types of storage tools such as baskets that can be arranged, and further, how to arrange the storage tools. In addition, it is possible to hook not only a storage tool but also a single item to be transported such as a towel on the hooked portion in the cart of this configuration.

  In the cart having the first configuration, it is preferable that the hooked portion has a configuration (second configuration) that is a protrusion protruding in a direction substantially orthogonal to the bridging direction. According to this configuration, it is easy to suppress an increase in the number of parts when providing the hooked portions arranged in the bridging direction. That is, this configuration is preferably a configuration in which the protruding portion is provided integrally with the bridge portion. However, this configuration is not intended to exclude the configuration in which the protruding portion is a separate member from the bridge portion. Moreover, according to this structure, it can be made easy to prevent omission about various types of storage tools.

  In the cart of the first or second configuration, the one end edge of the bridge portion has a wave-like structure in which a plurality of protrusions protruding in a direction substantially orthogonal to the bridging direction are provided at intervals, It is preferable that the hooked portion has a configuration (third configuration) that is a protrusion that forms the wave structure. This configuration assumes a configuration in which the protruding portion is provided integrally with the bridge portion, and can suppress an increase in the number of components when the hooked portion is provided.

  The cart having the second or third configuration preferably has a configuration (fourth configuration) in which the protruding portion protrudes substantially upward when the cart is in a standing posture. According to this configuration, it is possible to obtain a configuration in which a storage tool or the like mounted on the cart is difficult to drop off.

  In the cart having any one of the first to fourth configurations, one wheel is attached to each of the pair of support columns, and the standing posture of the cart can be maintained on the frame portion. It is preferable that a configuration (fifth configuration) including a leg portion that exhibits a function of locking the wheel in the standing posture is employed. According to this configuration, the number of wheels can be reduced, and since it is not necessary to provide a lock mechanism on the wheels, the manufacturing cost of the cart can be reduced.

  In the cart having any one of the first to fifth configurations, a plurality of the bridge portions provided with the hooked portions are arranged in a direction substantially parallel to the longitudinal direction of the support column (sixth configuration) ) Is preferably employed. According to this configuration, it can be expected that the degree of freedom is further increased with respect to the number and types of storage tools that can be arranged, and further, the way of arranging the storage tools.

  ADVANTAGE OF THE INVENTION According to this invention, it is a cart suitable for carrying storage tools, such as a basket, Comprising: A cart with which a user can use freely according to a use purpose and liking can be provided.

Schematic explaining the structure of the storage container mounted in the cart which concerns on embodiment of this invention.

  Hereinafter, a cart according to an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing a schematic configuration of a cart 1 according to an embodiment of the present invention. As shown in FIG. 1, the cart 1 generally includes a frame portion 11, traveling means 12 that enables movement of the frame portion 11, and a plurality of (four in this embodiment) bridges attached to the frame portion 11. And a portion 13.

  The frame part 11 is configured using, for example, metal or resin. The frame portion 11 includes a pair of struts 111 and 111 arranged substantially parallel to each other. On one end side (upper end side) of each column 111, a grip portion 112 is formed which is a portion of a user who pushes the cart 1 or pulls the cart 1. The grip portion 112 may be obtained, for example, by bending one end side of the support 111, or may be configured by a member different from the support 111 and attached to the support 111. Further, a rubber cover or the like may be attached to the grip portion 112 for the purpose of preventing slipping, for example.

  A first beam that is provided on the frame portion 11 on the end side (lower end portion side) opposite to the side on which the grip portion 112 is provided of the pair of support columns 111 and 111 and connects the pair of support columns 111 and 111. Part 113 is included. The pair of struts 111 and 111 and the first beam portion 113 are in a substantially orthogonal relationship with each other. The pair of struts 111, 111 and the first beam portion 113 may be integrally configured by bending one member, or each member is configured as a separate member, and each member is connected and fixed. It may be.

  Further, the frame part 11 is substantially orthogonal to a plane parallel to both the support pillar 111 (longitudinal direction) and the first beam part 113 (longitudinal direction) from each of the pair of support pillars 111 and 111. A leg 114 projecting in the direction is included. The pair of leg portions 114, 114 are arranged symmetrically. Further, a second beam portion 115 is formed between the pair of leg portions 114 and 114 to connect them. The second beam portion 115 prevents the leg portion 114 from wobbling with respect to the column 111.

  The traveling means 12 is constituted by wheels (two in total) attached to the tip of the end (lower end) opposite to the side where the grip portion 112 is provided of each column 111. In the present embodiment, the traveling means 12 is composed of two wheels in consideration of the manufacturing cost. However, the number of wheels constituting the traveling means is not limited to two, and may be changed as appropriate. Good.

  The bridge 13 is fixed to the pair of struts 111 and 111 so as to bridge between the pair of struts 111 and 111. The bridge part 13 can be comprised using a metal and resin, for example. The bridge portion 13 may be fixed to the pair of support pillars 111 and 111 by, for example, a screwing method, or a configuration using fitting between an engaging convex portion and an engaging concave portion.

  In the present embodiment, the four bridge portions 13 are arranged in parallel at a predetermined interval in a direction substantially parallel to the longitudinal direction of the support column 111. The configuration of these four bridge portions 13 is the same. It is. Moreover, the number of the bridge parts 13 attached to a pair of support | pillars 111 and 111 may be changed suitably not only in four, but depending on the case, it may not be plural but one.

  At one end edge (upper edge) of the bridge portion 13, there are a plurality of protrusion portions 131 protruding in a direction substantially orthogonal to the bridging direction of the bridge portion 13 (in the present embodiment, there are five, but the number thereof). May be changed as appropriate). In other words, one end edge of the bridge portion 13 has a wave-like structure due to the presence of the protrusion 131. The protrusion 131 is an example of the “part to be hooked on which an object can be hooked” in the present invention. The protruding portion 131 provided in a plate shape is provided so as to protrude substantially upward from the bridge portion 13 when the cart 1 is in the standing posture (the posture shown in FIG. 1 is the standing posture).

  The protrusion 131 is preferably formed integrally with the bridge portion 13, but in some cases, the bridge portion 13 and the protrusion 131 may be configured as separate members. In addition, the plurality of protrusions 131 are arranged in a row at intervals in the direction of bridging between the pair of struts 111 and 111 (the bridging direction), but in some cases, they are arranged in a zigzag shape in the bridging direction. It doesn't matter.

  Note that the outer shape of the protrusion 131 is not particularly limited to the shape shown in FIG. However, for example, it is preferable that the outer periphery is rounded in consideration of the safety of the user. For example, it is preferable that the front end side is wide so that the loop body (such as a hook handle) that is hooked is not easily detached. Furthermore, the protrusion does not necessarily have a plate shape, and may have a shape that exhibits a hooking function by, for example, bending a rod shape.

  Next, the function and effect of the cart 1 configured as described above will be described.

  FIG. 2 is a schematic view when the cart 1 according to the embodiment of the present invention is viewed from the side, and shows the state where the cart 1 is stationary in a standing posture on the traveling surface S (the ground surface or the floor surface). As shown in FIG. 2, the cart 1 is supported from the outside (human hand or the like) with respect to the traveling surface S by being supported by the pair of legs 114 and 114 and the pair of wheels 12 and 12. It is possible to maintain a standing posture. And since a pair of leg parts 114 and 114 exhibit the function which locks rotation of a pair of wheels 12 and 12, even if it does not support from the outside with a hand etc., a stationary state can be maintained.

  That is, according to the cart 1 of this embodiment, it is not necessary to attach a lock mechanism to the wheel 12, and it is easy to reduce the cost. Further, since the operation of the lock mechanism is unnecessary, the cart 1 of the present embodiment is easy to handle. Furthermore, since the standing posture can be maintained using the pair of leg portions 114, 114, the number of wheels can be reduced (there is no need to use four wheels). The cart 1 of this embodiment can reduce the cost.

  FIG. 3 is a schematic perspective view showing a state where the basket 2 (an example of a storage tool) is mounted on the cart 1 according to the embodiment of the present invention. As described above, the bridge portion 13 is provided with a plurality of protrusions 131. For this purpose, as shown in FIG. 3, the hook 2 is mounted on the cart 1 by, for example, the handle 21 (loop-shaped portion) of the hook 2 being hooked on the protrusion 131. The handle 21 may be hooked using only one protrusion 131 (configuration shown in FIG. 3), or may be hooked using a plurality of protrusions 131.

  Since a plurality of protrusions 131 are provided on one bridge portion 13, a plurality of hooks 2 can be hooked on one bridge portion 13. Moreover, since it is the structure by which multiple bridge | bridging parts 13 are provided, many cage | baskets 2 can be mounted, and a user is responsive to the purpose and preference about the kind and number of the cage | baskets 2 to be mounted, and also how to arrange. Accordingly, it is easy to make a free design. Furthermore, since the bag 2 mounted on the cart 1 is simply hooked, the user can easily remove the bag 2 and move only the bag 2.

  FIG. 4 is a schematic perspective view showing a state in which the storage container 3 (another example of the storage tool) is mounted on the cart 1 according to the embodiment of the present invention. The storage container 3 includes a storage unit 31 for storing things and a hook unit 32 for hooking on the cart 1. As shown in FIG. 4, such a storage container 3 can also be hooked on the protrusion 131. In FIG. 4, two storage containers 3 are attached on the upper side, and one storage container 3 (to be exact, the size is different from that attached on the upper side) is attached on the lower side.

  In addition, when attaching the storage container 3 as shown in FIG. 4 to the bridge part 13, if the width | variety (length of an up-down direction) of the bridge part 13 is narrow, the storage container 13 may incline more than necessary. For this reason, it is preferable that the width of the bridge portion 13 is determined so that the above-described inclination hardly occurs.

  As in the case of the above-described bag 2, the user can easily make a free design for the type and number of the storage containers 3 to be mounted, and the manner of arrangement, according to the purpose of use and preference. Further, since the storage container 3 mounted on the cart 1 is simply hooked, the user can easily remove the storage container 3 and move only the storage container 3. Of course, different types of storage tools such as the basket 2 and the storage container 3 may be attached to the bridge portion 13 in combination.

  FIG. 5 is a schematic diagram illustrating the configuration of the storage container 3 mounted on the cart 1 according to the embodiment of the present invention. FIG. 5A is a schematic plan view seen from the lower side, and FIG. It is a schematic sectional drawing in the AA position of Fig.5 (a). As shown in FIG. 5, when the partition wall 33 is provided inside the hook portion 32 of the storage container 3, when the storage container 3 hooked on the protrusion 131 tries to shift in the bridging direction, the partition wall 33 is Abutting on the protrusion 131 prevents the deviation. That is, it can be said that the cart 1 of this embodiment has a structure that can easily prevent the storage container 3 from falling off.

  As shown in FIG. 2, in the cart 1, in a state where the cart 1 is stationary in a standing posture, the support column 111 is slightly inclined with respect to the vertical direction (the direction of the broken line in FIG. 2 corresponds). For this reason, the storage container 3 hooked on the protrusion 131 is also slightly inclined with respect to the vertical direction. For this reason, it is easy to take out an object (for example, a shampoo container) stored in the storage container 3.

  Here, the use example of the cart 1 of this embodiment is demonstrated supposing the case where the cart 1 is used in a nursing care facility etc. in order to carry a load to a bathroom. When used for such purposes, the package to be transported includes a container containing shampoo or rinse. A shampoo container etc. can be mounted in the cart 1 using the storage container 3 shown, for example in FIG. In addition, towels are included as other transported luggage. Since it is preferable to separate the towel before and after use, for example, two baskets 2 (for example, those with a lid) shown in FIG. Can do. In addition, the baggage to be transported may include a trash box (a jar 2 as shown in FIG. 3 may be used). According to the cart 1 of this embodiment, it is possible to attach these loads in a free arrangement. In addition, for example, a single towel can be directly hooked on the protrusion 131 for temporary use.

  The embodiment described above is only an example of the present invention. The configuration of the embodiment described above may be changed as appropriate without departing from the technical idea of the present invention.

  For example, the cart 1 of the embodiment described above may be configured such that the user can disassemble and assemble. For example, the frame unit 11 may be configured to be divided into a plurality of parts, and the wheel 12 and the bridge unit 13 may be configured to be detachable from the frame unit 11. Such a configuration makes it convenient to store and transport carts that are not used.

  Moreover, the cart 1 of the embodiment described above may be configured such that a part thereof can be folded. Also in this case, it is convenient to store and transport carts that are not used.

  Further, in the cart 1 of the embodiment described above, the configuration of the plurality of bridge portions 13 is the same, but the plurality of bridge portions 13 are different from each other (for example, the number and shape of the protruding portions 131 are different). It does not matter.

  In addition, the cart of the present invention is not limited to use in a nursing facility or the like, but can be used for various purposes such as shopping and gardening. In this sense, the cart of the present invention can be called a universal cart.
