BACKGROUND OF THE INVENTION
The present invention relates to a shopping cart used for purchasers in a store such as a supermarket.
[0002]
[Prior art]
Shopping carts can be nested for reasons such as the ease of organizing and storing a large number of units and the saving of space for organizing and storing them. That is, one shopping cart can receive a part of another shopping cart from the rear from the rear.
[0003]
The shopping cart includes a cart having a handle for pushing and a basket for supporting a shopping basket (hereinafter simply referred to as “cage”) that is disposed below the handle and is supported by the cart, and temporarily stores products. and a received.
[0004]
In the conventional shopping cart, the basket receiver is configured by a plurality of pairs of arms that are spaced apart from each other and extend toward the rear of the carriage so as not to interfere with reception of other shopping carts during nesting ( Utility model registration No. 3068822).
[0005]
The car usually has a rectangular opening upper end, and the car can be supported by the car receiver by placing a pair of opening edge portions facing each other on a pair of arms of the car receiver and hooking them.
[0006]
However, because of the deformation of the cage due to the good or bad way of hooking the cage to the arm, the action of external force on the cage, etc. There was a problem that the opening edge easily detached from the arm and the car dropped out of the shopping cart. In addition, there is a problem that the conventional car receiver cannot be applied to cars of different sizes.
[0007]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a shopping cart having a basket receiver that is disposed below the handle for pushing the shopping cart and that stably supports the basket and does not obstruct the nesting of the shopping cart. It lies in the fact. Another object of the present invention is to provide a shopping cart including a basket receiver that can be similarly applied to cars of different sizes.
[0008]
[Means for Solving the Problems]
The shopping cart according to the present invention is capable of receiving a part of another shopping cart from the front from the rear thereof, and includes a carriage frame and a handwheel handle coupled to the carriage frame, A car receiver that is disposed below the handle and is swingably supported by the carriage, the car receiver being capable of supporting the car at its bottom. The bogie frame has a U-shaped front end portion that extends horizontally in the front-rear direction and extends toward the rear as a whole, and two rear end portions that are inclined upward from the rear portion of the front end portion. 1 frame member, a pair of inclined portions connected to both rear end portions of the first frame member and extending upward as a whole, a pair of vertical portions connected to an upper end of the inclined portion, and a rear side from an upper end of the vertical portion And a second frame member having a U-shaped end portion that extends obliquely upward.

DETAILED DESCRIPTION OF THE INVENTION
1 to 4, an example of a shopping cart 10 having a basket receiver 20 to which the present invention is applied is shown.
[0014]
The shopping cart 10 has a tapered front portion 12 and a divergent rear portion 14.
[0015]
From the rear, the shopping cart 10 can receive a part of another shopping cart 16 (see FIG. 5) that is identical to this from the front 12 of the other shopping cart.
[0016]
That is, this acceptance state is caused by pushing the front part 12 of another shopping cart 16 into the rear part 14 of the shopping cart 10 in front of it, and this acceptance or nesting efficiently organizes and stores a large number of shopping carts. can do.
[0017]
The shopping cart 10 includes a carriage 18 and a basket receiver 20 supported by the carriage. In the illustrated example, another car receiver 22 is further provided.
[0018]
Each of the car receivers 20 and 22 is loaded with a car 23 (FIG. 3) for temporarily storing products. The car 23 is generally used in a store such as a supermarket, and has a rectangular open upper end.
[0019]
As shown in FIG. 2, the carriage 18 includes a carriage frame 24 and a handle 26 for pushing the shopping cart 10. In the illustrated example, a postscript sheet 36 for an infant is disposed on the cart frame 24 of the shopping cart 10, and the cart 18 is covered with a cover 28 that resembles the front of the body of the automobile.
[0020]
As long as the nesting is possible, the shopping cart may be provided with a carriage frame in which, for example, a receiving portion for placing a product, a receiving plate, and the like are arranged instead of the infant seat.
[0021]
The bogie frame 24 supported by a plurality of casters 30 is composed of two frame members 32 and 34 formed by bending, for example, steel pipes or bars.
[0022]
One frame member 32 and the other frame member 34 define the front 12 and rear 14 of the shopping cart, respectively.
[0023]
One of the frame members 32 extending horizontally in the front-rear direction extends rearward toward the rear as a whole, and two rear end portions thereof are inclined upward. The other frame member 34 is connected to both rear end portions of the one frame member 32 and is connected to two leg portions extending upward as a whole, that is, a pair of inclined portions 34 a supported by a pair of casters 30 and upper ends thereof. It has a pair of vertical portions 34b and a U-shaped end portion extending obliquely upward from the upper end of the vertical portion toward the rear. The U-shaped end defines the handle 26.
[0024]
An infant seat 36 is disposed on the carriage 18. The seat 36 has a seat 38 and a backrest 40 connected to the seat 38 at an obtuse angle. The sheet 36 is made of, for example, a plastic molded body.
[0025]
The seat 36 is swingably supported by the carriage 18 at the top 42 of the backrest 40. More specifically, the handle 26 is supported at the front thereof.
[0026]
In order to support the seat 36, a bar 44 extending in the transverse direction or the width direction (width direction of the shopping cart 10) is fixed to the front portion of the handle 26. Further, an elongated attachment fitting 46 having a hat-shaped cross-sectional shape extending in the width direction is fixed to the back surface of the seat back 40, and a bar 44 penetrates the attachment fitting.
[0027]
As a result, the seat 36 is directed forward in the shopping cart 10 and can swing around the bar 44 in spaces defined by the rear portion of the frame member 32 and the front portion of the frame member.
[0028]
The seat 36 is also supported on the frame member 32 via a crank-shaped bar 48 on the lower surface of the seat 38. The crank-shaped bar 48 is disposed so as to protrude upward from the frame member 32 and is fixed to the frame member 32 at both ends thereof, and extends in a direction crossing the frame member 32.
[0029]
On the other hand, the seat 36 is provided with a concave groove 50 that opens to the lower surface of the seat 38 and extends in the width direction. Part of the crank-shaped bar 48 extends along the groove 50. As a result, the seat 36 is maintained so that it swings only to the front side and not to the back side, and its seat 38 is horizontal.
[0030]
According to this, when the handle is pushed for nesting and another shopping cart 16 is pushed into the rear space of the shopping cart 10 in front of it, the front end of the cover 28 defining the substantial front portion 12 of the shopping cart 10. The upper part hits the back surface of the backrest 40 of the seat 36 and exerts a pressing force on this. The seat 36 that has received the pressing force swings forward around the bar 44, and its seat 38 moves from an upper position of the crank-shaped bar 48 to a further upper position forward (see FIG. 5).
[0031]
Thereby, a part including the front part of the other shopping cart 16 proceeds further forward in the shopping cart 10 and is received in the shopping cart 10 to complete the nesting. As a result, the shopping carts 10 and 16 partially overlap.
[0032]
Instead of the illustrated example in which the infant seat is swingably supported at the top of the backrest, the infant seat swings around an axis extending in the width direction or transverse direction of the shopping cart, for example, at the bottom front end of the seat 38. It may be movably supported. According to this, at the time of nesting, the seat receives the pressing force of the other shopping cart 16 and rotates forward, so that it is brought forward. The front part of the other shopping cart 16 can be advanced to the space created by the advance of the seat.
[0033]
The car receiver 20 for placing the car 23 is disposed below the handle 26 and is swingably supported by the carriage frame 24 (more specifically, the other frame member 34).
[0034]
As shown in FIG. 2, the car receiver 20 includes an arm 54 that has an overall U-shape and a support member 56 that is fixed to the arm 54.
[0035]
The U-shaped arm 54 is disposed behind both vertical portions 34b of the frame member 34, and is pivotally attached to both vertical portions 34b at both ends thereof.
[0036]
In order to pivotally attach the U-shaped arm 54 to the frame member 34, a plate-like bracket 58 is attached to each vertical portion 34 b of the frame member 34, and a bolt that penetrates the bracket 58 and extends in the width direction of the frame 34. 60 is prepared. On the other hand, a plate 64 provided with a bolt hole 62 is attached to each end of the U-shaped arm 54.
[0037]
Both ends of the U-shaped arm 54 are arranged on the outside of the vertical portions 34b opposite to each other so that the plates 64 of the arm 54 are the brackets 58 of the frame, respectively, and penetrate the bracket 58 and the bolt hole 62 of the plate. A nut 66 is screwed to the bolt 60 to be engaged.
[0038]
Thereby, the U-shaped arm 54 located behind the vertical portion of the frame member 34 can swing around both bolts 60 extending in a substantially horizontal direction.
[0039]
Since the both ends of the U-shaped arm 54 are disposed outside the both vertical portions 34b of the frame member, one of the covers 28 positioned outside the inclined portion 34a of the frame member, in the illustrated example, the inclined portion 34a. Further swinging is prevented. In this state, the arm 54 is inclined slightly downward.
[0040]
In this downwardly inclined state of the arm 54, the support member 56 is in a substantially horizontal state and supports the car 23 placed thereon.
[0041]
The illustrated support member 56 is formed by bending a steel wire into a hat shape as a whole, and is placed on a rear end portion 54a of a U-shaped arm so as to extend across the same, and both side portions 54b of the arm. And both end portions 56b crossing the both side portions below them.
[0042]
The support member 56 has a size that allows the car 23 to be stably placed thereon. The car 23 placed on the support member 56 is restricted from moving in the horizontal direction by both side portions 54b of the arm, the seat 36, and a rising portion 56c formed by bending the support member body 56a. It is.
[0043]
The cage receiver 20 comprising the U-shaped arm 54 and the support member 56 receives the collision force from the front part of the other shopping cart 16 that is pushed into the shopping cart 10 for nesting, and the support member 56 moves its position forward and upward. It swings to change to. At this time, a part of the other shopping cart 16 including its front part can move forward in the shopping cart 10 through a space defined by the support member 56 and both side parts 54b of the arm ( see Figure 5).
[0044]
In order for the basket receiver 20 that receives the pressing force of the other shopping cart 16 to swing more smoothly, preferably, the rising portion of the support member of the basket receiver 20 that the front part of the other shopping cart 16 hits. 56c to place the rollers 68.
[0045]
The rollers 68 are rotatably supported at both ends by a pair of brackets 70 attached to the lower part of the rising portion 56c. When the front portion of the other shopping cart 16 hits the roller 68, the roller 68 rotates about the swing axis of the car receiver 20, that is, the axis parallel to the two bolts 60, and the front portion of the other shopping cart 16 rises to the rising portion 56c. In the case of directly hitting, the friction between the two is reduced and the front part of the other shopping cart 16 can be easily brought under the rising part 56c.
[0046]
The other car receiver 22 is supported by a handle 26. The cage receiver 22 has a main body 22a which is formed by bending a steel wire and is folded in a hat shape so that the car 23 can be placed, and both end portions 22b extending upward from both ends of the main body. . The main body 22a of the car receiver is disposed below the space surrounded by the handle 26, and both end portions 22b thereof are fixed to both side portions of the handle 26, respectively.
[0047]
However, the car receiver 22 is disposed at a height that does not hinder the swinging movement of the lower car receiver 20.
[0048]
Needless to say, the nesting of the shopping cart is performed with the car 23 excluded.
