Description

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

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

Due to its structure, when the round bar-shaped metal handle H is pivoted to the plastic cage body B in a tilted standing state at a certain angle, the mounting mechanism rises from the upper edge of the opening on the cage body B side. 1 is provided with a protruding guide portion 3 extending laterally along the through hole 2 for receiving the handle, while a remaining end portion 5 continuous with the rotating abutment portion 5 is provided at the tip position on the handle H side. It forms a bend.

<Problem to be solved by the invention> However, in the case of the above-mentioned known invention, the handle H is made of a round bar-shaped metal, and furthermore, the tip position of the handle H is a rotary abutment part 5 into the through hole 2, so that the handle H has a constant overhang length. is bent inward at a right angle, and the remaining end 6 of a certain length that fits within the recess 4 is bent forward or backward at a right angle while continuing to be located on the same plane as the rotating abutment part 5. I have to let it happen. Therefore, it is necessary to perform several steps of press work in manufacturing the handle H, which is extremely complicated and also increases the cost of the product.

In addition, since the handle H is a metal product and has a very special tip shape as described above, when assembling it with the basket body B, it is necessary to grasp the upper edge of the opening of the basket body B and hold it as shown in Fig. 4. As is clear from C, the remaining end 6 of the handle H must be passed through the through hole 2 from the outside while forcibly pushing it down inward. It is clear that this requires heavy labor and is inferior in assembly workability.

<Means for Solving the Problems> The present invention aims to improve such problems, and for this purpose, it includes a pair of front and rear plastic handles that are inverted U-shaped and have locking hooks at both end bases; A plastic cage body has a pair of front and rear legs for attaching a handle standing upright from the left and right long sides of the opening flange, and a locking hook is inserted into the handle receiving hole formed in the center of the leg. By penetrating the
In a shopping basket in which the handle is pivotally supported for rotational operation in an undulating manner relative to the opening flange of the basket main body, a stopper convex protrudes from the arcuate portion of the locking hook, and engages with the stopper convex. By forming a concave groove for regulating the rotation angle in the form of a concentric arc locus with a larger opening than the handle receiving hole on the outer surface of the leg piece, the handle can be placed almost horizontally with respect to the opening flange of the basket body. The device is characterized in that it is set so that it can be positioned and held in a prone position and a standing position tilted at a constant 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 upwards, making the plurality of cage bodies A low in bulk. 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 handle receiving hole formed through the center of each leg piece 16, and it has a circular shape with a constant opening diameter when viewed from the side. There is. Similarly, 18 is a rotation section formed by cutting out a part of the outer surface of the leg piece 16 so as to be continuous with the handle receiving hole 17, thereby forming a concentric arc locus shape having an opening diameter larger than that of the receiving hole 17. It is a concave groove for regulating the angle, and the stepped portion 18a at one end of the arcuate trajectory positions and regulates the positioning of the handle B in the prone state, and the remaining stepped portion 18b at the other end similarly positions the handle B in the tilted upright state at a constant angle θ. It is designed to hold.

On the other hand, each of the handles B is also injection molded from colored plastic material into an overall inverted U-shape, and the bases of both separated ends are connected to the leg pieces 16.
The locking hook 19 for the handle receiving hole 17 is bent into an arc shape as shown in FIGS. 7-9. By passing this into the receiving hole 17 from the outside, when assembled with the leg piece 16, the handle B can be freely rotated.

However, a stopper protrusion 20 is integrally projected downward from the arcuate portion of each locking hook 19, and this is configured to properly engage with the groove 18 of the leg piece 16, so that the handle B only rotates within the angular range regulated by the groove 18.

In other words, when the stopper protrusion 20 is engaged with the step part 18a at one end of the groove 18, the handle B remains in an almost horizontal state as shown in FIGS. 6 and 10, and the stopper protrusion 20 is also When the other end of the groove 18 is engaged with the step portion 18b, the handle B is in the first position.
As shown in Figure 1, the tilted standing state at a constant angle θ is maintained.

In this case, it is preferable to set the constant angle θ to such an extent that the horizontal bar grips 21 of both handles B lightly touch each other as shown by the chain lines in FIG. 1 (for example, about 67 degrees). In addition, when the handle B is in the down position, the bar grip 21 is attached to the opening flange 1.
It is preferable to float the flange 15 by a certain distance S so as not to come into contact with the front and rear short sides of the flange 15 . Further, it is preferable that a reinforcing rib 22 extending perpendicularly to the leg piece 16 when viewed from above is protruded from the position of the leg piece 16 standing up from the opening flange 15 as a so-called backing state to the flange 15.

<Effects of the Invention> As described above, in the present invention, a pair of front and rear plastic handles B having locking hooks 19 at both end bases of an inverted U-shape, and a pair of handles for attaching the handle from the left and right long sides of the opening flange 15 are provided. A plastic basket body A is provided with a pair of front and rear leg pieces 16 erected, and a locking hook 19 is passed through the handle receiving hole 17 formed in the center of the leg piece 16. Connect the handle B to the opening flange 1 of the basket body A.
In particular, in the shopping basket which is pivotally supported so as to be freely rotatable in an undulating manner with respect to the locking hook 19, a stopper protrusion 20 is protruded from the arcuate portion of the locking hook 19, and a turn that engages with the stopper protrusion 20 is provided. The groove 18 for regulating the movement angle is inserted into the handle receiving hole 17.
By forming a notch on the outer surface of the leg piece 16 in the form of a concentric arc locus with a larger opening than the handle B, the handle B can be placed in a substantially horizontal position with respect to the opening flange 15 of the basket body A, and can be placed at a constant angle θ. Since it is set so that it can be positioned and maintained in an inclined upright state, it has the effect of reliably solving the problems of the prior art mentioned at the beginning.

In other words, since the handle B of the present invention is made of plastic material, the entire structure including the locking hook 19 with the stopper protrusion 20 can be molded extremely easily.
It can be assembled into the handle receiving hole 17 with high efficiency in a so-called one-touch operation type, and there is no need to press the cage body A from its opening flange 15 at all.

In addition, in addition to the handle receiving hole 17, the leg piece 16 of the basket body A has a cutout groove 18 that engages with the stopper protrusion 20 and regulates the rotation angle of the handle B. , the handle B can be stably positioned and held with respect to the opening flange 15 of the basket body A in an almost horizontal lying state and an upright state inclined by a certain angle θ, and as a result both handles in the inclined upright state can be held. By holding the bar grip 21 of B as it is, it can be easily carried by hand, and by keeping it in a horizontal position, a plurality of basket bodies A can be stacked and stored in a small and compact size without any trouble.

The necessary configuration for this purpose is extremely simple, and the mass production effect can be expected to the maximum.
It can be said that it is very profitable.
