DETAILED DESCRIPTION OF FIGURES

(24) FIG. 1 shows, in a perspective view, an exemplary embodiment of a stackable transport trolley 10 according to the invention, here a stackable shopping trolley 10.

(25) The shopping trolley 10 has a chassis 12 and a basket 14.

(26) The chassis 12 furthermore has a supporting frame 16 and a wire framework 18 arranged on the supporting frame 16, wherein the wire framework 18 supports the basket 14. Four wheels 20 are fastened to the supporting frame 16 via respective wheel suspensions 22.

(27) The supporting frame 16 is bent here from a semi-finished product and is of U-shaped design.

(28) In the assembled state of the shopping trolley 10, the free ends of the supporting frame 16 are arranged on the rear side of the shopping trolley 10.

(29) The supporting frame 16 itself is of planar design, i.e. it is located in a plane. In other words, this therefore relates to the fact that the bending of the supporting frame 16 takes place only in one plane, and therefore the supporting frame is only bent two-dimensionally and not three-dimensionally.

(30) As furthermore arises from FIG. 2, which shows the supporting frame 16 and the wire framework 18 arranged thereon, the wire framework 18 consists of two wire brackets 24, a cross strut 26 (also cross bracing 26) and a wire frame 28.

(31) The wire framework 18 has two wire brackets 24 which sit on the supporting frame 16.

(32) The wire brackets 24 are of substantially U-shaped design.

(33) The wire bracket 24 furthermore has three rectilinear portions 24a, 24b and 24c.

(34) The two wire brackets 24 are of identical design here.

(35) In the assembled state, as shown in FIG. 1, the basket 14 is at least partially placed on the central portion 24b of the wire bracket 24.

(36) The horizontal cross bracing 26 is arranged in the front-side region of the central portion 24b of the wire bracket 24.

(37) Furthermore, the wire brackets 24 are arranged at the free ends of the supporting frame 16 and, furthermore, are arranged symmetrically with respect to the longitudinal axis of the shopping trolley 10.

(38) A tube section 30 is fitted on the supporting frame 16 at each of the free ends.

(39) A first free end of the wire bracket 24 is in each case at least partially inserted into the tube section 30, specifically, according to FIG. 2, that free end of the wire bracket 24 which adjoins the first rectilinear portion 24a of the wire bracket 24 (cf. FIG. 3).

(40) A second free end of the wire bracket 24 rests on the supporting frame 16, here that free end of the wire bracket 24 which adjoins the third portion 24c of the wire bracket 24.

(41) Furthermore, an element of the suspension 22 of the wheel 20 of the shopping trolley 10 is inserted in the tube section 30.

(42) The wire frame 28 furthermore has two rising basket fastening brackets 32.

(43) The basket fastening brackets 32 are of substantially identical design, specifically are V-shaped.

(44) Furthermore, the wire frame 28 is formed integrally.

(45) Based on the assembled state of the shopping trolley 10, the wire frame 28 furthermore has, on the rear side, a cross strut 34 which connects the two basket fastening brackets 32 to each other.

(46) In addition, based on the assembled state of the shopping trolley 10, the wire frame 28 in each case has, on the front side, a free end which in each case rests on one of the wire brackets 24. The two free ends point inward here, based on the assembled state of the wire framework 18.

(47) The wire frame 28 has the advantage of only involving a single component which is at the same time stable. Said component is fastened in a fixed position on the wire bracket, for example by welding.

(48) Load forces of the basket 14 can be absorbed by means of the wire frame 28 and at the same time a transverse connection can be provided by the cross strut 34.

(49) A wire frame 28 of this type can be produced in a simple manner, with it being possible for all of the components of the wire framework to be produced from a wire having a thickness within the range of between 10-15 mm, for example approx. 13 mm.

(50) The wire can be in particular solid material. However, it is also conceivable to use a corresponding tube.

(51) The basket 14 is pushed onto the basket fastening bracket 32 and thereby supported. For this purpose, the basket 14 has two basket fastening bracket receptacles, into which the basket fastening brackets 32 are pushed. At the same time, the bottom of the basket 14 sits on the cross struts 26 and 34 (cf. FIG. 6).

(52) As is furthermore shown in FIGS. 6, 7 and 8, the basket 14 is secured against being pulled off by means of a two-part locking clip 36 which consists of two halves 36a and 36b.

(53) As is apparent in particular from FIG. 8, the locking clip 36 is inserted in such a manner that it is clipped in the tip of the V-shaped basket fastening bracket 32 such that it cannot be pulled off upward. As is furthermore apparent from FIG. 7, the locking clip 36 is inserted through a corresponding opening in the basket 14 and clipped there.

(54) As is furthermore apparent from FIGS. 4 and 5, the basket 14 in its bottom region has latching catches 38, by means of which the basket 14 is clipped on the wire framework 18.

(55) The side walls of the basket 14 are formed by a nest structure 40, wherein the nest structure 40 is formed by a plurality of nest struts 42. The nest struts 42 for a side wall of the basket 14 are formed here in the region facing the ground in such a manner that they have a larger cross section there than in the region which faces the basket opening. This is apparent, for example, from FIG. 5A and from the details H and G according to FIG. 5B and FIG. 5C.

(56) The basket 14 itself is designed as a plastic basket.

(57) As is furthermore apparent from FIG. 1, in the assembled state, the basket 14 is connected to a pushing handle 44.

(58) In a customary form, the pushing handle 44 has a coin deposit system 46, wherein the use of a coin deposit system 46 of this type is not compulsory, but rather is optional.

(59) As is furthermore shown in FIGS. 9 to 11, for the connection of the pushing handle 44 to the basket 14, the pushing handle 44 is provided on both sides with two push-in blades 48, by means of which the pushing handle 44 can be inserted into the basket 14.

(60) For this purpose, the basket 14, as is apparent from FIG. 12, has a push-in opening 50 on both sides.

(61) The push-in opening 50 here has a double bevel, with a first bevel 52 and a second bevel 54.

(62) The stops 56 and 58, which are of counter-part-like design, of the pushing handle 44 are positioned against the edge of said bevels 52 and 54 of the push-in opening 50 in the assembled state.

(63) In the assembled state, the push-in blades 48 of the pushing handle 44 are inserted into the push-in openings 50 in a latching manner.

(64) As is furthermore apparent from FIG. 10, the push-in blades 48 have a plurality of stiffening ribs 60 which rise vertically out of the plane of the push-in blade and structure the push-in blade 48 repeatedly in a T-shaped manner.

(65) The push-in blade 48 is divided substantially centrally into an upper push-in blade half 62 and a lower push-in blade half 64.

(66) As is apparent in particular from FIG. 10 and FIG. 12, a bolt receptacle 66 is provided between the two push-in blade halves 62 and 64, through which a fastening screw 68 can be screwed in in order to provide additional securing of the pushing handle 44 against being pulled off from the push-in opening 50 of the basket 14.

(67) The bolt-like securing element 68, which is designed here as a screw bolt or screw, can also be another suitable type of bolt-like securing element 68.

(68) As is furthermore apparent from FIG. 11, in the assembled state, an identification chip 70, here an RFID chip, can be arranged between the push-in blade 48 and a wall of the push-in blade opening 50.

(69) As is furthermore apparent from FIG. 13, in the assembled state, the basket 14 has, on the front side, a nest-like front wall 72 which is formed from a plurality of nest struts 42.

(70) Furthermore, an overlapping wall 74 which overlaps the upper edge of the front wall 72 is provided in the front region of the basket 14. The overlapping wall 74 projects into the interior of the basket 14 and therefore forms a type of impact reinforcement and retaining wall for products placed into the basket 14.

(71) The overlapping wall 74 furthermore has an information field 76.

(72) The information field 76 is in turn provided with a transparent covering 78 which can be clipped in in the edge region of the information field 76 (also see FIG. 14 and FIG. 15 which show the clipping-in tabs 78a and 78b of the transparent covering 78).

(73) A corresponding clipping-in opening is in each case provided on the edge of the information field 76 for receiving the tabs 78a and 78b.

(74) FIGS. 16 to 20 show a child seat 80 for the shopping trolley 10.

(75) The child seat 80 which is illustrated in FIG. 16 for a shopping trolley 10, as illustrated in FIG. 1, is illustrated in the use position.

(76) The child seat 80 has a seat board 82 and a backrest 84. The seat board 82 is connected to the backrest 84 in a sliding or pivotable manner and is guided here in two longitudinal sliding guides 86. The rear side of the basket 14 of the shopping trolley 10 is formed by the wall 88 which can pivot into the interior of the basket 14 about a horizontal axis 90 located at the top.

(77) The backrest 84 is mounted with its lower boundary 92 or with downwardly leading supports 94 on the wall 88 so as to be pivotable to a limited extent thereon about a horizontal axis 96 which is located in the lower region of the wall 88.

(78) This is also shown in detail in FIG. 19.

(79) The seat board 82 is mounted either in a pivotable or sliding manner on the wall 88.

(80) This type of arrangement and construction is already known from the prior art, for example from EP 1 451 053 B1.

(81) The backrest 84 can be pivoted onto the wall 88 while the wall 88 together with seat board 82 and backrest 84 can be pivoted about the horizontal axis 90 into the interior of the basket 14 for the purpose of pushing together a plurality of shopping trollies 10.

(82) In the unfolded state of the backrest 84, the seat board 82 can be guided downward in the sliding guide 86 and latched there in a corresponding manner by means of a latching lug 98. This is shown in detail in FIGS. 19 and 20.

(83) The backrest 84 is formed integrally and is substantially designed in the manner of a holding body.

(84) Furthermore, the backrest 84 is of substantially H-shaped design, wherein the connection of the two limbs of the H shape is designed as a backrest wall 100.

(85) The backrest 84 has side members 102 which are in the manner of hollow bodies and are provided with reinforcing struts in their interior. The reinforcing struts 104 are shown, for example, in FIG. 17 since the latter are apparent on the outer narrow sides of the side members 102, via which the structures in the manner of hollow bodies in the interior of the side members are accessible.

(86) The cavities 106 are located between the reinforcing struts 104 which, in the assembled state, are accessible in the region of the backrest wall 100 via openings 108 which are provided on that side of the backrest 84 which faces the basket interior and which are designed in the manner of slots.

(87) Between the reinforcing struts 104, cavities 106 are likewise provided in the region below the backrest wall 100, which cavities, in the assembled state, are accessible in the region below the backrest wall 100 via point-like openings 110 located on the side-member inner side.
