Abstract

The invention relates to a stackable shopping cart (1), consisting of a frame (2) that supports a basket (3) for receiving goods. One bearing (8) each is mounted on a common horizontal axis (7) on both walls (4) of the basket (3) formed by horizontal and vertical rods (5, 6). A tray (21) for receiving additional goods that is mounted outside the basket (3) and that can be swiveled backwards is articulated to said bearings (8). The invention is further characterized in that every bearing (8) is provided with support elements (18) that are adapted to support themselves on at least one of the horizontal and vertical rods (5, 6) and that at least one securing device (19) is provided per bearing (8), which is designed to lock in position the respective bearing (8) on one of the side walls (4).

Description

Stackable shopping cart

(1) technical field

The present invention relates to a kind of Stackable shopping cart, a vehicle body is arranged, a goods basket is arranged on the vehicle body, the goods basket surrounds with Metallic rod anyhow, respectively establish a supporting plate that horizontal axis is identical on two sidewalls, specific and shelf that can swing backward also are housed outside the goods basket, and its swinging mounting plate is also on goods basket two sidewall par axis.

(2) background technology

Shopping cart described in the EP0 684 176 B1 patent documentations belongs to up-to-date technology.

(3) summary of the invention

The objective of the invention is to weld also after making and shelf can be installed on the shopping cart for above-mentioned shopping cart further improves its two supporting plates.

Solution of the present invention is, a kind of Stackable shopping cart is provided, this go-cart has a vehicle body, a goods basket is arranged on this vehicle body, this goods basket surrounds with Metallic rod anyhow, respectively establish a supporting plate that horizontal axis is identical on two sidewalls of goods basket, specific and shelf that can swing backward also are housed outside the goods basket, each supporting plate all has support zone, this support zone will be supported on the Metallic rod of one of a level and vertical metal bar at least, and each supporting plate has a latch at least, so that relevant supporting plate can be fixed on the sidewall of goods basket, wherein each supporting plate has a position to block the regulation end of a vertical metal bar.

By these technical innovative approachs, later just can shelf be fixed on the goods basket without a doubt, this support zone design feature is that supporting plate is just accurately in place after loading onto goods basket sidewall and before locking, locking is just become flexible in order to prevent, the supporting plate latch has a buckle, and this buckle can make supporting plate buckle on goods basket level or the vertical metal bar.

(4) description of drawings

The present invention will be described in detail with an embodiment, also enumerate the different models of extending simultaneously.All accompanying drawings are:

(5) specific embodiment

Fig. 1 has showed a Stackable shopping cart 1, and its method of designing is known, save space, same size shopping cart 1 can phase interfix heap.The vehicle body 2 of shopping cart 1 has a goods basket 3.The sidewall 4 of goods basket 3 uses all anyhow that

Metallic rod

5,6 surrounds, and Fig. 1 has illustrated

Metallic rod

5,6 structures, here people should not go to understand definition anyhow too narrowly, horizontal in this case expression goods basket 3 Metallic rod 5 from after extend forward, perpendicular expression bonding jumper 6 extends from bottom to top.Respectively adorn a supporting plate 8 on the sidewall 4 of goods basket 3, this supporting plate 8 is positioned on the par axis 7.Specific and shelf 21 that can swing backward also are housed outside goods basket 3, its swinging mounting plate 8 is on 3 two identical sidewall horizontal axiss 7 of goods basket, these class shelf 21 have two forks 22 and a goods to stack face, its details illustrates in EP 0 684 176 B1 patent documentations, thereby needn't be repeated in this description, supporting plate 8 will be fixed on the sidewall 4 of goods basket 3 with a latch 19 at least, and is loaded on the outside, has intactly showed the left side wall 4 of goods basket 3 in the sketch.

Fig. 2 is supporting plate 8 structural representations that are contained on left side wall 4

Metallic rod

5,6 joinings.Be contained in the 8 one-tenth mirror images of supporting plate and supporting plate on the right side wall 4.Each supporting plate 8 all has support zone 18, this support zone can be fixed on a horizontal metal bar 5 and the vertical metal bar 6 at least, all have a carrying surface 9 made from band steel such as each supporting plate 8, on this carrying surface, fixed an axle sleeve 16 made from round steel, each carrying surface 9 is on the running condition position of supporting plate 8, and each axle sleeve 16 should be on the par axis 7 after installing.Such as on each carrying surface 9, being support zone 18 all with upside and left vertical limit.Edge 10 and 11 is near on a horizontal metal bar 5 and the vertical metal bar 6, as shown in Figure 3.The right edge 12 of each carrying surface 9 is carried out flange with axle 23, also be used as the support zone 18 on the vertical metal bar 6 in addition, front end in right edge 12 has a chimb 13 that protrudes the plane, this chimb is near the vertical metal bar, be shape such as columniform axle sleeve 16 before chimb 13, the fork 22 of shelf 21 is fixed on this cylindrical shaft and puts and can swing.Tapped bore 17 in the axle sleeve 16 can screw in a locking piece, and this locking piece is in order to prevent that shelf 21 from getting loose from the axle sleeve 16 of two supporting plates 8.

Fig. 3 has described supporting plate 8 on the left side wall 4 of goods basket 3 and the fork 22 on the shelf 21 with partial enlarged drawing and lateral plan.In the figure as seen, be benchmark with the inboard of goods basket 3, the vertical metal bar 6 of goods basket 3 is put in the inboard, and the horizontal metal bar 5 that intersects with vertical metal bar 6 is then in the outside of goods basket.Such as the upside 10 of the carrying surface 9 of supporting plate 8 near horizontal metal bar 5.The left vertical edges 11 of carrying surface 9 is close to the vertical metal bar 6 on the left side among the figure, and the back side 14 of carrying surface 9 is opposite with axle sleeve 16, is arranged in the vertical metal bar 6 that figure mediates.The right edge 12 of carrying surface 9 is joined with the vertical metal bar 6 on the right, and chimb 13 equally also is near this root Metallic rod 6.Chimb 13 and right edge 12 have formed a support zone 18 equally.There is a latch 19 on left surface 15 sides of carrying surface 9, this latch has a buckle 20, this buckle is crossed horizontal metal bar 5 and is returned the other end, block firm left surface 15 with this, see twice bending and block left surface 15 and the buckle 20 of horizontal metal bar 5 has formed " C " font that almost seals from the side.Supporting plate is fixed on the assigned position with support zone 18, and without buckle 20, but can be along the 6 downward landings of vertical metal bar after loosening.This moment, latch 19 can prevent that at least supporting plate 8 from gliding, thereby had locked supporting plate 8.

8 of supporting plates described in Fig. 1 to Fig. 3 have been expressed a kind of in many feasible methods.Supporting plate 8 can be made the plastics diecasting, matches with the crooked position and the angle of cut of horizontal metal bar 5 and vertical metal bar 6 so that can be better.So the plastic stent plate 8 that matches with the predetermined angle of cut can be contained in by the angle of cut of horizontal metal bar 5 and vertical metal bar 6 fully.So the support zone 18 of supporting plate 8 only is supported on a horizontal metal bar 5 and the vertical metal bar 6, and supporting plate 8 is fixed on its assigned position.Relevant therewith latch 19 join with supporting plate 8 and should snap at least in Metallic rod 5 and the Metallic rod 6 wherein on one, latch 19 is used to also prevent that supporting plate 8 from getting loose from sidewall 4.Latch 19 can be formed with a part or a plurality of part, comprises screw element or at least one rivet.Also can consider the version that other are different at this.
