It is a top view explaining the shopping cart which concerns on 2nd Example.

  First, a shopping cart according to a first embodiment of the present invention will be described with reference to FIGS.

  As shown in the figure, the front head 2 is disposed in front of the main body A (the left side in FIGS. 2 and 3, the same applies hereinafter), and the seat 4 is disposed substantially in the center.

  The main body A is composed of a main body frame 1 and a handle portion 3.

  As shown in FIG. 3, the main body frame 1 is formed in a substantially U shape having a narrow front and a wide rear (right side in FIGS. 2 and 3, the same applies hereinafter), and the rear end 1a has a rear end. The distance between the parts 1a is set to be sufficiently larger than the front end part 1b formed in a curved shape. For this reason, the main body frame 1 has an open shape in which the width increases from the front end 1b toward the rear end 1a. The rear side end 1a has a dimension larger than the dimension in the longitudinal direction of a shopping basket (not shown).

  Since the main body frame 1 has the above-mentioned shape, when another subsequent shopping cart enters between the rear side end portion 1a of the main body frame 1, the front side end portion 1b of the shopping cart can be easily received. Is possible.

  Side plates 5 are arranged on both sides of the rear end 1a. The side plate 5 is located behind the seat 4 and closes both sides of the space 6 formed below the handle portion 3 and prevents children from entering the space 6 from the side. . Moreover, the upper surface of the side plate 5 has a function as the placing portion 5a of the shopping basket.

  The upper end portion of the frame 2a constituting the front head 2 is formed in a curved shape, and the curved portion is configured as a contact portion 2a1. The abutting portion 2a1 abuts against the rear surface of the back portion 4a of the shopping cart on the front side when the shopping cart is continuously parked and transmits a forward force. For this reason, the height of the frame 2a (the position in the height direction of the contact portion 2a1) is appropriately set in relation to the height of the backrest 4a of the seat 4. Further, the contact portion 2a1 is preferably covered with a material having a small friction coefficient.

  Therefore, when the shopping cart is parked, when it is inserted between the rear end portions 1a of the main body frame 1 of the shopping cart on the front side, the abutting portion 2a1 of the frame 2a becomes the seat 4 of the shopping cart on the front side. Abuts against the rear surface of the backrest 4a. As the shopping cart further invades, the backrest 4a can be rotated around the rotation center. Thus, when nesting a plurality of vehicles (connected parking), the volume can be reduced and the storage space can be reduced.

However, the front and rear surfaces of the front head 2 do not have to be formed in a concavo-convex shape so that the front head 2 can be completely fitted.

  The handle portion 3 is held and operated and operated by a person using the shopping cart. For this reason, the handle portion 3 has a U-shaped frame 3 a disposed on the rear side end portion 1 a side with respect to the center of the main body frame 1. The frame 3a has a pair of column portions 3a1 standing up from the main body frame 1, and an inclined portion 3a2 is formed in which the upper end portion of the column portion 3a1 is inclined obliquely upward toward the rear side, and the inclined portion 3a2 is further formed. Are connected to each other. And the handle 3b for a user to hold | grip from the inclination part 3a2 to the connection part 3a3 is formed.

  On the upper part of the pair of pillar portions 3a1 constituting the frame 3a, a beam 8 is spanned by connecting these pillar portions 3a1, and the backrest portion 4a of the seat 4 is connected to the beam 8 by an arrow a, FIG. It is pivotally supported so that it can rotate in the b direction.

  The seat 4 is for a child to sit on, and has a backrest portion 4 a pivotally supported by the beam 8 and a seat surface portion 4 b fixed to the upper surface of the main body frame 1. Further, side plates 9 are respectively provided on the left and right sides of the seat surface portion 4b. The side plate 9 has an end on the rear side continuous to the end on the front side of the side plate 5 described above, and the upper end reaches the side of the lower end 4a2 of the backrest 4a. Further, the upper surface of the side plate 9 is formed to be an armrest for a child sitting on the seating surface 4b. Further, the side plate 9 is formed with a support piece 9a that is refracted inward, and is configured such that the rear surface of the backrest part 4a of the seat 4 abuts on the support piece 9a to maintain the abutting position.

  The backrest portion 4a is formed in a curved shape in plan view so as to cover and protect the child when sitting, and a pivotal portion 4a1 pivotally supported by the beam 8 is provided on the rear side on the upper end portion. And the length of the lower end portion 4a2 is substantially in contact with the seating surface 4b. Further, the rear surface of the backrest portion 4 a is exposed below the handle portion 3, and the space 6 is defined by the backrest portion 4 a and the handle portion 3.

  For this reason, in a state where no other shopping cart is accommodated on the rear side, the back portion 4a has the rear surface in contact with the support piece 9a of the side plate 9 and the lower end portion 4a2 is substantially in contact with the seat surface 4b. Further, in a nesting state in which another shopping cart on the rear side is accommodated, the backrest portion 4a pushed by the front head 2 of this shopping cart rotates in the direction of arrow a, and this rotational position is maintained.

  The seat surface portion 4 b has a leg 4 b 1 at an end on the front side, and the leg 4 b 1 is fixed to the main body frame 1. Further, both sides of the seat surface portion 4b are also connected to the side plate 9. For this reason, the weight of the child sitting on the seat surface portion 4b can be supported by the legs 4b1 and the side plates 9.

  In the shopping cart configured as described above, when another shopping cart on the rear side enters the space 6 formed below the rear end 1a of the main body A and the handle portion 3 with the front head 2 at the top. The abutting portion 2 a 1 of the front head 2 abuts on the rear surface of the backrest portion 4 a of the seat 4. As the other shopping cart further intrudes, the backrest 4a rotates about the beam 8 in the direction of arrow a.

  The front and rear shopping cart front heads 2 come into contact with the rear end of the front shopping cart seat surface 4b and reach the forward limit. Therefore, it is possible to reduce the parking area required when a plurality of shopping carts are arranged in front and back.

  Next, the structure of the shopping cart according to the second embodiment will be described with reference to FIGS. In the present embodiment, the same parts as those in the first embodiment described above or the parts having the same functions are denoted by the same reference numerals and description thereof is omitted. Further, the shopping cart according to the present embodiment differs from the shopping cart according to the first embodiment described above only in the configuration of the seat 4. Therefore, the configuration of the seat 4 will be described.

  The seat 4 of the shopping cart according to the present embodiment is different from the first embodiment in which the backrest portion and the seat surface portion are configured separately, and the backrest portion 4a and the seat surface portion 4b are integrally configured. For this reason, the seat 4 can rotate the backrest 4a and the seating surface 4b integrally around the beam 8.

  The backrest part 4a and the seat surface part 4b which comprise the seat 4 are mutually connected by the rotating shaft 4c so that rotation is possible. Further, side plates 11 similar to the side plates 9 in the first embodiment are provided on both sides of the seat 4, and the end portions 4c1 of the rotating shaft 4c are guided to the mutually opposing surfaces of the side plates 11. Support protrusions 11b for positioning the guide groove 11a and the seat surface portion 4b are formed.

  Therefore, when nesting is performed, that is, when another shopping cart is parked after the shopping cart, if the front head 2 of the rear shopping cart is inserted into the space 6 of the front shopping cart, the contact portion 2a1 Comes into contact with the rear surface of the seat back 4a. Then, the seat 4 is flipped up in the direction of arrow a around the beam 8 spanned on the frame 3a of the handle portion 3. At the same time, the seat surface 4b also rotates about the rotation shaft 4c with its own weight with respect to the backrest portion 4a.

  When the backrest part 4a is pushed upward by the front head 2 of the shopping cart on the rear side and pivots upward, the seat surface part 4b pivots in the opposite direction with the pivot fulcrum 4c serving as a fulcrum. That is, the seat surface portion 4b is bent to the opposite side to the backrest portion 4a when in use, and a space 10 sufficient to accommodate the front head 2 of the rear shopping cart is formed in this portion. be able to. Further, since the dummy handle 2b is guarded by the bent seat surface portion 4b, it is possible to prevent damage due to the tip of another shopping cart entering from behind. For this reason, it is possible to reduce the parking volume required when a plurality of shopping carts are arranged in the front-rear direction.

  On the other hand, when one of the rearmost parts is pulled out from the nesting state, the backrest part 4a of the seat 4 of the shopping cart that is flipped up in the shopping cart in front of it is rotated in the direction of the arrow b by its own weight. The protrusion 4c1 of the shaft 4c moves along the guide groove 11a provided on the side plate 11 and comes into contact with the lower end of the guide groove 11a. At the same time, the lower end of the seat surface portion 4b abuts on the support protrusion 11b of the side plate 11 and is rotated with respect to the backrest portion 4a by this guidance, so that the seat surface portion 4b of the seat 4 is positioned front and rear. Then, the user can shop with the child seated on the seat 4 of the shopping cart holding this state.

  Although the seat 4 is configured to be rotatable about the beam 8 as a rotation axis, it may be configured such that a rotation protrusion is provided on both sides of the backrest portion 4a without using a rotation axis like a beam. Of course. Similarly, various configurations can be selected for the backrest portion 4a, the seat surface portion 4b, and the rotating structure.

  The shopping cart according to the present invention is advantageous when shopping with a child sitting on the seat, and can reduce the area required for parking when parking a plurality of shopping carts in succession. It is possible and advantageous.
