Description

The present invention relates to a hand push member.

Some carts used at work sites such as construction sites have a structure in which single pipes can be inserted into the four corners of the main body of the cart. For example, Patent Literature 1 discloses a carriage provided with corner members at four corners into which a single pipe can be inserted as a push rod. With such a configuration, the user of the trolley can use the single tube inserted into the main body of the trolley as a push rod when moving the trolley.

In the present embodiment, the traveling portion 30 has six casters: four casters 31 arranged at the four corners of the carriage main body 20 and two casters 31 arranged at the center in the front-rear direction and separated from each other to the left and right. have The casters 31 are attached to the carriage main body 20 via attachment plates.

The hand pushing member 40 is a member for a user to hold the hand when the carriage 1 is driven. A user grips and pushes or pulls the hand pushing member 40 to make the carriage 1 travel. The hand-pushing member 40 is elongated with a length of about 1000 mm. The hand pushing member 40 is attached to the carriage body 20 by inserting the lower end into the insertion hole 23 of the corner member 22 . The carriage 1 also has four push members 40 which are inserted into the insertion holes 23 of the respective corner members 22 . All four hand pressing members 40 have the same configuration. However, it is not limited to the case where four pushing members 40 are attached, and one, two, or three pushing members 40 may be attached.

FIG. 2 is a perspective view showing an example in which a part of the pushing member 40 is disassembled. 3(a) is a side view of the pushing member 40, and FIG. 3(b) is a plan view of the pushing member 40. FIG.
The hand pressing member 40 has a body member 41 as a body portion, a protection member 43, a reinforcement member 50, and an identification member 60 as an identification portion.
The main body member 41 is a rod-shaped or elongated pipe-shaped member. The body member 41 is made of, for example, an aluminum alloy and formed by extrusion. The body member 41 has a metallic color such as silver, for example, and is colored by alumite treatment, plating treatment, or the like. Further, the main body member 41 is a circular tube having an outer diameter of, for example, 42 to 45 mm (here, 44 mm), which is smaller than a so-called single tube (single tube pipe) so that the user can easily grasp it. In addition, the body member 41 is internally reinforced in a cross shape in order to improve strength. A single pipe refers to a carbon steel pipe for general structural use defined in JIS G 3444, and is a circular pipe with an outer diameter of 48.6 mm.
However, the main body member 41 is not limited to the dimensions described above, and various rod-shaped or tubular members, the above-described single pipes, and the like can be applied.

The protective member 43 protects the user's hand from touching surrounding objects when the user grips the pushing member 40 . In addition, the protection member 43 serves as an index indicating the maximum loading height when the transported goods are loaded. The protective member 43 is fixed to the upper side of the main body member 41 by bolts, rivets, or the like, at a predetermined distance from the upper end thereof. The protective member 43 is preferably fixed at a position 100 to 200 mm away from the upper end of the main body member 41 . Furthermore, it is preferable to fix them at a position separated by 120 to 180 mm. The portion of the hand-pressing member 40 above the protective member 43 functions as a grip portion with which the user holds the hand.

As shown in FIG. 3A, the protective member 43 has a protective portion 44 and a mounting portion 45, which are integrally formed. In addition, the protective member 43 has mounting holes that open vertically for inserting the main body member 41 therein. The protective member 43 is made of a resin material such as nylon, and is integrally formed by injection molding. The protective member 43 has, for example, a different color from that of the main body member 41, and is colored by mixing a resin material with a coloring agent. Note that the protective member 43 may have the same color as the body member 41 .

The protective portion 44 has a disk shape that protrudes outward from the outer peripheral surface of the main body member 41 and has an outer diameter larger than that of the main body member 41 . The outer diameter of the protective portion 44 is set to a dimension in which the user's hand gripping the main body member 41 does not protrude from the protective portion 44 (set inside the outline in plan view). . Specifically, the outer diameter of the protective portion 44 is preferably in the range of 100 to 140 mm, more preferably in the range of 110 to 130 mm. However, specific dimensions are not particularly limited.

The attachment portion 45 has a cylindrical shape extending downward from the lower end of the protection portion 44 and has an outer diameter larger than that of the main body member 41 and smaller than that of the protection portion 44 .
When attaching the protection member 43 to the body member 41, the body member 41 is inserted into the attachment hole of the protection member 43, and the attachment portion 45 is attached to the body member 41 at a predetermined position from the upper end of the body member 41 with bolts, rivets, or the like. fixed to

The reinforcing member 50 is fixed to the lower end of the main body member 41, more specifically, to a position close to the lower end with bolts, rivets, or the like. The reinforcing member 50 reinforces the strength of the body member 41 and suppresses rattling between the body member 41 and the insertion hole 23 when the body member 41 is inserted into the insertion hole 23 of the corner member 22 . The reinforcing member 50 is made of, for example, an aluminum alloy and formed by extrusion. The reinforcing member 50 has a metallic color such as silver, for example, and is colored by alumite treatment, plating treatment, or the like.

4(a) is a sectional view taken along the line II shown in FIG. 3(a), and FIG. 4(b) is a view showing the insertion hole 23 of the corner member 22. As shown in FIG.
As shown in FIG. 4A , the reinforcing member 50 is cylindrical and has an outer diameter larger than that of the body member 41 . The reinforcing member 50 has a plurality of (here, two) bulging portions 51 that partially bulge in the radial direction of the outer peripheral surface. The length (vertical dimension) of the reinforcing member 50 is set to approximately the same length as the depth of the insertion hole 23 of the corner member 22 . Further, the reinforcing member 50 has a mounting hole 53 that opens vertically for inserting the main body member 41 therein.
When attaching the reinforcing member 50 to the main body member 41, the main body member 41 is inserted into the attachment hole 53 of the reinforcing member 50, and the reinforcing member 50 is attached to the main body member 41 at a predetermined position from the lower end of the main body member 41 with bolts, rivets, or the like. 41.

On the other hand, as shown in FIG. 4B, the insertion hole 23 into which the reinforcing member 50 is inserted has a space 54 as a recess for allowing the bulging portion 51 of the reinforcing member 50 to be inserted. Therefore, by aligning the bulging portion 51 with the space 54 and inserting the reinforcing member 50 fixed to the main body member 41 into the insertion hole 23, the pushing member 40 is positioned at a predetermined position.

The identification member 60 is a member for identifying the user of the hand pushing member 40 . Here, the user means a contractor contracted for construction from a construction company. At a work site, for example, a plurality of contractors, such as an air-conditioning construction contractor, an electric construction contractor, and a sanitation-related construction contractor, perform construction work in parallel. Each trader borrows the carriage 1 and the pushing member 40 from the construction company and uses them. Therefore, it is preferable that the user of the push member 40 present at the work site can be identified at a glance. In this embodiment, the identification member 60 is given a different color for each user of the push member 40 in order to identify the user of the push member 40 .

The configuration of the identification member 60 will be described below.
The identification member 60 is a cap-shaped member, here a bottomed cylindrical member. The identification member 60 is made of a resin material such as nylon, and is integrally formed by injection molding. The identification member 60 has, for example, a different color from that of the main body member 41, and is colored by mixing a resin material with a coloring agent. Here, the identification member 60 is given one of the three primary colors of red, green, and yellow, or one of blue, white, orange, gray, and pink, depending on the user. attached. By adding blue, white, orange, gray, and pink in this manner, the visibility of the identification member 60 can be improved.

The identification member 60 has a tubular portion 61 and an end portion 62 .
The tubular portion 61 is cylindrical and has a mounting hole 63 that opens downward for inserting the upper end of the body member 41 . The length (vertical dimension) of the tubular portion 61 is preferably in the range of 10 mm to 40 mm. The visibility of the identification member 60 is improved by making it 10 mm or more, and excessive enlargement of the identification member 60 can be suppressed by making it 40 mm or less. Moreover, it is preferable that the outer diameter of the tubular portion 61 is larger than the outer diameter of the main body member 41 and smaller than the outer diameter of the protective portion 44 . However, specific dimensions are not particularly limited.
The end portion 62 has a substantially plate shape, is positioned at the upper end of the cylindrical portion 61, and closes the mounting hole 63 from above. In addition, the outer surface of the boundary between the tubular portion 61 and the end portion 62 is connected by a curved surface.

When attaching the identification member 60 to the main body member 41 , the identification member 60 is attached by inserting the upper end of the main body member 41 into the attachment hole 63 of the identification member 60 . When the identification member 60 is attached to the main body member 41 , the upper end of the main body member 41 is covered with the identification member 60 . The identification member 60 is attached by being press-fitted into the body member 41 . Therefore, the identification member 60 can be removed by pulling it out from the body member 41 , and the identification member 60 can be attached to and detached from the body member 41 . By making it detachable in this way, the identification member 60 of a different color can be easily replaced.

Here, the state in which the identification member 60 is attached to the body member 41 will be described with reference to FIG. As shown in FIG. 3A, when the identification member 60 is attached to the main body member 41, the identification member 60 is positioned at the upper end of the hand-pushing member 40, which is a conspicuous position. It is easily visible. Further, since the identification member 60 has the cylindrical portion 61 , the identification member 60 can be visually recognized from any position in the circumference of 360° around the hand pressing member 40 . Further, since the identification member 60 covers the upper end of the main body member 41, it is possible to improve the aesthetic appearance of the hand pressing member 40. FIG.

Further, as shown in FIG. 3B, when the outer diameter of the identification member 60 is D1 and the outer diameter of the protective portion 44 is D2, D1<D2. That is, in plan view, the identification member 60 is located inside the outer peripheral surface of the protection portion 44 . Therefore, even if the user grabs the identification member 60 with his/her hand and moves the carriage 1, the protective portion 44 contacts an object such as a wall before the user does with the hand, so that the identification member 60 cannot be grasped. The user's hand is prevented or restrained from contacting the object. It is preferable that the outer diameter D1 of the identification member 60 is as close to the outer diameter of the main body member 41 as possible so that the protective portion 44 comes into contact with the object before the hand. That is, as shown in FIG. 3A, the horizontal distance L1 from the outer peripheral surface of the identification member 60 to the outer peripheral surface of the body member 41 is equal to the horizontal distance from the outer peripheral surface of the identification member 60 to the outer peripheral surface of the protection portion 44. It is preferably smaller than the directional distance L2.
In addition, FIG. 3(b) shows a state in which the hand pushing member 40 is inserted into the insertion hole 23, and a part of the protection portion 44 overlaps the carriage body portion 20 (see the two-dot chain line).

In this way, the push member 40 has an identification member 60 colored differently for each user to identify the user of the push member 40 . For example, a red identification member 60 is attached to the push member 40 used by an air-conditioning contractor, and a yellow identification member 60 is attached to the push member 40 used by an electrical contractor. A green identification member 60 is attached to the hand-pressing member 40 used by the trader. Therefore, the user of the hand pressing member 40 can be easily identified by visually checking the identification member 60 which is colored differently for each user.
Further, the identification member 60 is detachable with respect to the main body member 41 . Therefore, even if the user of the pushing member 40 changes, the identification member 60 of a different color can be easily replaced without damaging the body member 41 or the identification member 60 .

Next, the colors applied to the identification member 60 for each user will be described.
Here, an example will be described in which insert metal fittings with different colors are used for each user at a work site where the carriage 1 and the hand pushing member 40 are used.
FIG. 5 is a diagram showing an example for explaining a construction method of the metal insert 70. As shown in FIG.
An insert metal fitting is a metal fitting embedded in a concrete frame at a work site. The insert metal fitting 70 of this embodiment is attached to the formwork 75 before concrete is placed, and the nut member is embedded in the concrete frame by dismantling the formwork 75 after concrete is placed.

The insert fitting 70 has a nut member 71 and a resin frame member 72 . The nut member 71 has a female screw portion 73 held by a resin frame member 72 . The resin frame member 72 is arranged around the nut member 71 and has nails 74 for attaching the metal insert 70 to the mold 75 . Here, the resin frame members 72 have the same shape but different colors. That is, the insert metal fitting 70 is prepared in different colors of the resin frame material 72 .

Next, the construction method of the insert metal fitting 70 is demonstrated.
First, as shown in FIG. 5(a), in order to construct the insert metal fitting 70, a nail 74 is used in a state in which a resin frame member 72 is brought into contact with the surface of the formwork 75 on which concrete is to be placed. Install.

Next, as shown in FIG. 5(b), the formwork 75 is dismantled after placing the concrete. By dismantling the formwork 75, the metal insert 70 is embedded in the concrete skeleton. At this time, the female screw portion 73 of the nut member 71 and part of the resin frame member 72 are exposed on the surface of the concrete frame.
Finally, as shown in FIG. 5(c), a suspension bolt 76 or the like is screwed into the female screw portion 73 exposed on the surface of the concrete frame, so that the structure is attached to the periphery of the concrete frame via the suspension bolt 76. can be placed.

Here, at the work site, the work of arranging the structures is performed for each trader. For example, a contractor who performs air-conditioning facility construction pipes an air-conditioning duct or the like as a structure. In addition, electrical contractors arrange electric wires, lighting fixtures, and the like as structures. Sanitation-related work contractors install water supply and drainage pipes. Therefore, each trader needs to attach the insert metal fittings 70 to be used in advance to the formwork 75 at the position where the structure is to be arranged. At this time, in order to identify which trader installed the insert metal fittings 70 after dismantling the formwork 75, different color insert metal fittings 70 are installed for each trader.

In this embodiment, the color applied to the metal insert 70 and the color applied to the identification member 60 are made substantially the same for each user. For example, if there is a user who uses the insert fitting 70 with the resin frame material 72 colored red, the identification member 60 colored red is attached to the pushing member 40 used by the user. In this way, the user of the hand pressing member 40 can be more easily identified by making the color applied to the metal insert 70 and the color applied to the identification member 60 approximately the same for each user. can be done.
Note that the colors applied to the metal insert 70 include red, green, yellow, blue, white, orange, gray, pink, and the like. On the other hand, black is rarely adopted as a color applied to the insert metal fitting 70 because it is inconspicuous. Therefore, the identification member 60 of the hand pressing member 40 used by a trader who does not use the metal insert 70 can be colored black.

As described above, the embodiments of the present invention have been described in detail with reference to the drawings, but the above-described embodiments merely show specific examples for carrying out the present invention. The technical scope of the invention is not limited to the embodiments. The present invention can be modified in various ways without departing from its gist, and these are also included in the technical scope of the present invention.

In the above-described embodiment, the case where the identification portion is the cap-shaped identification member 60 has been described, but the present invention is not limited to this case. For example, the identification part may be a sticker-like member that is colored for each user. Moreover, although the case where the identification member 60 is attached to the main body member 41 has been described, the identification member 60 may be attached to a member such as the protection member 43 that constitutes the hand pressing member 40 . Even in this case, the identification section is preferably detachable.

Moreover, although the case where the identification member 60 is cap-shaped has been described, it is not limited to this case. For example, the identification member 60 may have a shape of only the tubular portion 61 . Further, the shape of the tubular portion 61 is not limited to a circle in plan view, and may be polygonal.
Also, the protective member 43 itself may be used as the identification portion. That is, the pushing member 40 may have a protective member 43 colored for each user.
Further, the hand pressing member 40 may omit the reinforcing member 50 and the lower end of the body member 41 may be directly inserted into the insertion hole 23 .
