Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a handle attachment device for a shopping basket that is carried by a purchaser of goods in a supermarket or other self-service retail store.

<Prior art> In general, the handle attachment device for this type of shopping basket, which is commonly known as a "self-service basket", is
No. 52988 is known.

<Problem to be solved by the invention> However, in this structure, the extra end 6 is bent out at a substantially right angle at the tip position on the handle H side as a constant length from the rotation abutment part 5. On the other hand, the through hole 2 on the side of the basket body B which should receive the rotary abutting part 5 is only a straight circular opening with a dimension smaller than the overhang length of the remaining end part 6. During assembly, grasp the upper edge of the opening of the basket body B, forcefully push it inward, and insert the remaining end of the handle H into the through hole 2 from the outside, as shown in Figure 4C. 6 must be passed through. The operation is extremely complicated and requires heavy labor, and the excessive push-down operation force may lead to accidents such as accidental breakage of intersecting ribs in the cage body B.

Further, the tip of the handle H made of metal in the shape of a round bar is bent inward at a right angle with a constant overhang length as the rotation abutment part 5 to the through hole 2, and then the rotation abutment part While being located on the same plane as 5, the remaining end 6 with a constant overhang length is also at a right angle,
Bending forward or backward requires several steps of press work, and it is difficult to maintain high accuracy in the overhang length dimension. If the dimension (the mutual distance between the upright part and the remaining end of the handle) is smaller than the depth and length of the through hole 2, the handle H cannot be rotated smoothly, and the metal handle H will damage the attachment mechanism 1 of the plastic cage body B.

On the other hand, if the overhanging length of the rotary abutting portion 5 is larger than the depth of the through hole 2, the handle H
The upright part does not properly engage the descending guide part 3 of the basket body B, and the handle H cannot be stably positioned and held in the upright state at a certain angle.

<Means for Solving the Problems> The purpose of the present invention is to improve such problems, and for this purpose, the handle mounting leg piece that stands up from the opening flange of the plastic cage body has a A conical hole for receiving the handle is formed through the metal handle, and the conical hole for receiving the handle expands toward the metal handle, and at the base end of the inverted U-shaped frame rod of the metal handle, the metal handle extends inward from the frame rod at right angles and is bent. A horizontal pivot rod portion and an angle regulating rod portion that extends and bends at a right angle from the pivot rod portion are provided, and the angle regulating rod portion and the pivot rod portion are inserted into the conical hole of the leg piece. By penetrating the main body from the outside,
The above-mentioned handle is pivotally supported on the opening flange of the cage main body so as to be freely rotatable in an undulating manner, and the angle regulating rod portion of the handle is viewed from the side of the cage main body,
By bending the handle in a direction that intersects the upright part of the frame rod by a certain angle and locking the protruding tip thereof to the opening flange of the cage main body from above, the handle is attached to the opening flange of the cage main body. It is characterized in that it is set so that it can be positioned and maintained in an upright state at a certain angle.

<Example> Hereinafter, the configuration of the present invention will be described in detail based on the illustrated example.
In Figure 2, A is a rectangular parallelepiped cage body with an open top, which is integrally injection molded from a colored plastic material. Reference numeral 11 denotes its horizontal bottom wall, which is provided with a plurality of grounding seats 12 that integrally project downward. Reference numeral 13 refers to the front, rear, left and right surrounding standing walls that stand up from the periphery of the bottom wall 11, and are given an inclination gradient that gradually widens as it goes upward, so that the plurality of cage bodies A are lowered and lowered. It is now possible to stack them.

The surrounding standing wall 13 is defined by the number of groups of ribs 14 that intersect with each other to form an opening that allows mutual ventilation or visibility between adjacent ribs. This means that the bottom wall 1
The same applies to No. 1, but the details thereof are omitted from illustration. Reference numeral 15 denotes an opening flange which is bent in a vertical L-shape section from the upper end of the surrounding standing wall 13 and continuously extends outward, and has a rectangular frame shape that is almost similar to the bottom wall 11 when viewed from above. It is showing.

Further, reference numeral 16 denotes a pair of handle attachment legs that vertically extend upward from the left and right long sides of the opening flange 15, respectively, as a pair of front and rear handles. It is pivoted so that it can be operated freely, and can be used as a portable device by grasping its handle B.

That is, in FIGS. 3 to 6, in which the pivot points are extracted and enlarged, 17 is a conical hole for receiving a handle formed through the center of each leg piece 16, and has a circular shape when viewed from the side. The opening diameter d gradually increases toward the outside of the cage body A. In that case, it is preferable that the enlarged opening diameter d is set to be approximately the same as the length of the extension of the angle regulating rod portion of the handle B, which will be described later, or to be slightly larger than the length of the extension.

Reference numeral 18 denotes a locking recessed groove recessed from the top surface of the opening flange 15 in the basket main body A while being located inwardly adjacent to the leg piece 16, and receives and locks the angle regulating rod portion of the handle B. However, the top surface of the opening flange 15 may be cut out as a through hole in place of the groove 18 as long as it can lock the protruding tip of the angle regulating rod. As mentioned above, the installation of the through hole and groove 18 may be omitted.

On the other hand, each of the handles B is made of aluminum or other metal round bar material and is bent into an overall inverted U-shape, and the frame rod portions 19 forming the inverted U-shape are separated at both ends. A horizontal pivoting rod portion 20 that extends out and is bent at right angles, and the pivoting rod portion 20
The angle regulating rod portion 21 has a constant overhang length L and is bent at a right angle from the end of the overhang.

In that case, when viewed from the side of the cage body A, the angle regulating rod portion 21 is projected in a direction intersecting the upright portion of the frame rod portion 19 by a certain angle α, and the end of the projection extends from the side of the cage body A. When engaged with the groove 18, the upright portion of the frame rod portion 19 of the handle B is positioned and held in an inclined upright state at a constant angle β with respect to the opening flange 15 of the basket body A as shown in FIG. It's becoming like that. In the tilted upright state, the horizontal bar grip portions of both handles B are set so as to lightly abut each other, as suggested from FIG.

In addition, the overhang length dimension L of the angle regulating rod portion 21
is set to be as short as possible so that when the handle B is rotated about the pivot rod 20, it will not protrude too far from the peripheral edge of the leg piece 16. It is also conceivable to cover the overhanging tip of the regulating rod portion 21 with an elastic cap. Furthermore, in order to reinforce the position directly below the leg piece 16 and the groove 18, it is preferable to install a reinforcing rib 22 on the opening flange 15 of the cage body A in a so-called backing state.

In any case, according to the above configuration, each handle B
The angle regulating rod part 21 and the pivot rod part 20 are connected to the cage body A.
By passing the leg piece 16 into the conical hole 17 from the outside, it is possible to assemble the leg piece 16 so that it can freely rotate in an undulating manner about the pivot rod part 20. At this time, the opening diameter d of the conical hole 17 is Since it is enlarged toward the outside, the angle regulating rod portion 21 and the pivot rod portion 20 can be received smoothly and reliably.

In addition, in the assembled state, the handle B can lie down almost horizontally with respect to the opening flange 15 of the basket body A as shown in FIGS. In order to receive the so-called tension action by locking with the
This means that it is correctly positioned and held in the tilted upright position. Therefore, the horizontal bar grip portions of both handles B can be held as they are, and the device can be easily carried by hand.

In addition, the handle B is at both separated end positions,
Since it is assembled and pivotally supported on the leg piece 16 of the basket body A in a so-called restrained state, supporting it by the conical hole 17 also poses a problem for stable rotation of the handle B. Never.

On the contrary, the conical hole 17 allows the handle B to be assembled easily and efficiently.

<Effects of the invention> As described above, in the present invention, the handle attachment leg piece 16 that stands up from the opening flange 15 of the plastic basket body A has a handle receiving leg piece 16 that expands toward the outside of the basket body A. The conical hole 17 is formed through the frame rod 17, and at the base end of the inverted U-shaped frame rod 19 of the metal handle B, there is a horizontal pivot rod that extends inward from the frame rod 19 at right angles and is bent. 20, and an angle regulating rod portion 21 that extends and bends at a right angle from the pivot rod portion 20, and inserts the angle regulating rod portion 21 and the pivot rod portion 20 into the conical hole 17 of the leg piece 16; By penetrating the cage body A from the outside, the handle B can be pivotally supported in an up-and-down manner with respect to the opening flange 15 of the basket body A, and the angle regulating rod portion 21 of the handle B can be inserted into the opening flange 15 of the basket body A. When viewed from the side, there is a certain angle α with the upright portion of the frame rod portion 19.
By bending the handle B in the intersecting direction and locking the protruding tip to the opening flange 15 of the cage main body A from above, the handle B is inclined at a constant angle β with respect to the opening flange 15 of the cage main body A. Since it is set so that it can be positioned and maintained in the upright state, it has the effect of reliably solving the problems of the prior art mentioned at the beginning.

In other words, the angle regulating rod 21, which is bent and protrudes from the pivot rod 20 of the handle B, is tension-locked to the opening flange 15 of the basket body A, so that the handle B is held at a constant angle β with respect to the opening flange 15.
Since the handle is positioned and held in the inclined upright position, the handle can be held in a stable manner at all times, regardless of the relationship between the overhanging length of the pivot rod 20 and the depth of the conical hole 17. This makes it possible to restrict B to a tilted standing state. Therefore, the press working of the pivot rod portion 20 and the angle regulating rod portion 21 can be carried out without any particular restrictions.
Excellent in mass production.

Furthermore, since the conical hole 17 for receiving the handle is literally opened in a shape that expands on the outside of the basket body A, the operation of assembling the regulating rod portion 21 and the pivot rod portion 20 of the handle B from the outside is not necessary. It is possible to assemble the basket body A very easily and efficiently without having to forcefully press the basket body A inward from the opening flange 15, which is very useful for this type of shopping basket that is used in large quantities.

Furthermore, if the locking groove 18 that receives the overhanging tip of the angle regulating rod portion 21 is formed correspondingly to the opening flange 15 of the cage body A, the danger of the overhanging tip being exposed can be effectively prevented. It can be said that it is even more advantageous.
