a side view or in an end view the framework of a trained according to a third embodiment of the invention ten shopping bag with wheels.

10 and 11 show diagrammatically and

in side view two details of this bag in a larger one Scale.

In the illustrated embodiments

the shopping bag has a rigid U-shaped frame a horizontal base 1 and vertical legs 2 and 3.

This frame can by means of a single.

bent tubular element or formed by three straight sections, which are connected to each other with the help of corresponding connectors are combined. In the embodiment shown in FIGS. 1 and 2, the front leg is v / ird 2 formed by a straight section, while the base 1 and the rear leg 3 by the same L-shaped bent tubular member are formed.

To base 1 is any suitable one

Way, in particular by welding or bolting, a traverse 4 attached, which ends at its ends in two arms 5 carrying two coaxial wheels 6.

Two more crossbars 7 and 8 are also attached to the base 1 at the front and rear, which one carry the plate 9 forming the base of the (preferably removable) shopping bag.

The walls of this bag, which e.g.

one that has been made waterproof, if necessary by means of suitable struts 1O stiffened canvas are indicated in FIGS. 1 and 2 with 11.

A swiveling roller 12, which is loaded in a fork head 13 connected to a vertical pin 14

109851/0166 _BAD ORIGINAL

- 5 - 3141-71

Gert is at the front of the frame by inserting the pin 14 into the lower open end of the front vertical Leg 2 attached. The wheels 7 and the roller 12 are preferably externally covered with a rubber or other coating Elastomer covered.

The upper ends of legs 2 and 3 of the

Racks are rigid with a horizontal tubular rod 15 stiffened, especially with the help of tees or pairs of reinforcement clamps 34 welded to one another in a T-shape.

The height of this rod 15 is determined so that it can serve as a handle for carrying the bag on your arm.

Since then the middle zone 15 * of this rod is grasped by hand, at least this zone has a diameter sufficient for comfortable grasping. the Zone can of course be locally reinforced for this purpose by an elastic or inelastic sleeve.

The rod 15 is too low to control the travel of the shopping bag on the ground.

This control is carried out by means of a tubular frame 16 with the general shape of an inverted one U, the two feet 17 and 18 of which are connected at the bottom to the upper ends of the legs 2 and 3.

This frame 16 is bent so that

the volume lying above the central zone 15 of the rod 15 remains free, so that there is always enough space for the extended arm, which carries the bag by grasping this zone 15.1 with the hand, and that a straight horizontal arm parallel to the rod 15 Section 19 is created, which serves as a handle for controlling the travel of the bag on the floor next to the user.

The height of this section 19 which

in any case is considerably higher than that of the rod 15, must correspond to the height of the hand of the user standing next to the bag resting on the floor.

This amount can be advance once and for all

determined according to the average height of the user. V The framework 16 can then by a simple extension of the

10985 1/0166

- 6 - 3141-71

Legs 2 and 3 of the frame are formed and with this consist of a single bent tubular element.

In the preferred embodiments,

however, the height of the framework 16 can be adjusted according to the size of each user.

For this purpose, the legs 2 and 3 of the frame are straight, vertical tubular elements open at the top, and the also straight vertical PÜsse 17 and 18 of the framework slide telescopically in these legs.

Not shown, with screw or

Locking means with a clamping effect are of course provided, to fix the framework after adjusting its height.

In this way, at will of the

perpendicular distance V between the two parallel pipe elements 15 and 19 can be regulated, which is between 10 cm or can vary more for tall people and 30 cm or more for small people.

The horizontal constant distance H between these two elements 15 and 19 is two times between 5 and 10 cm.

It should be noted that if this distance H is relatively small (e.g. of the order of magnitude 6 cm), the horizontal section 19 is supported horizontally slightly on the inside of the extended arm, which the Bag by grasping the rod 15 by hand. This can be very awkward to the lower part of the worn Removing the bag from the wearer's legs, making it more convenient to carry.

Except for the two types of use above

(Carrying or pulling, i.e. driving in the immediate vicinity of the user) the bag can also be steered when it is driving some distance in front of or behind the user (use as push or tow car).

For this purpose, the frame 16 has permanent

or temporarily a part which extends further backwards than the puss 18 and higher upwards than the section 19.

In Pig. 1 to 5 illustrated embodiment is this upper rear part of the skeleton

109851/0166

- 7 - 3141-71

the two elements 18 and 19 interconnecting tubular Handle 20.

This handle is curved in the shape of a question mark, the semicircular loop of which follows extends at the rear and forms a handle for controlling the movements of the bag from a distance.

This handle can be rigidly connected to the sections 18 and 19.

In the variant embodiment shown in FIGS. 1 to 4, it can be rotated horizontally 180 ° about the vertical axis of the foot 18, so that the horizontal expansion of the pocket is reduced and ' their placement in a closet or other volume of small dimensions is facilitated (Fig. 4).

The upper end of the handle 20 is then on

the Re3t of the framework 16 on one in the vertical extension the axis of the foot 18 lying point 21 is articulated.

The handle is in its working position

held by means of a suitable locking system, in particular by means of a sliding ring 22, which at the same time the two adjacent tubular ends of the handle and the the rest of the skeleton is covered under contact and thus keeps in alignment.

If such a ring 22 is provided,

To unlock the handle, it is sufficient to move the ring as far as possible until it exposes the joint 21.

In certain cases, the handle cannot be used to guide the bag moving at high speed protrude sufficiently far back over the pocket.

The handle can then with a special

Stalk combined or replaced by one at all.

In the embodiment of FIGS. 1 to 5

can be a removable straight handle 23, which normally is supported in its rest position by attached to one of the legs 2 and 3 fastening members 24, so on the Handle can be attached so that it reaches back to use the bag as a "push cart".

Eat to facilitate this attachment

109851/0166

- 8 - 3141-71

■ a straight pin 25 is provided in the axis of the handle 23, which enters horizontally into the interior of the handle 20 through an opening 26 and with a sliding fit in one in the Handle provided cylindrical shell 27 slides.

This connection is locked by pulling a screw 28.

So that the connection between the stem

23 and the handle correctly withstands the vertical forces that act on the handle, especially when tilting the bag for Exceeding the edges of a citizen's dough is exercised, this connection is reinforced by being in another Recess of the handle, a pinger 30 is inserted, which is parallel to the pin 25 and on the handle by means of a profile piece 31 is attached, which can be supported on the handle along a considerable plane of the same.

In the embodiment of the Pig. € and

if there is no handle, the upper end of the vertical rear foot 18 of the framework closes rather at right angles to the rest of the framework and forms an upwardly open one tubular receiving space.

This recording room receives an L-promoted

inigen handle with two straight sections of unequal length, namely a short section 32 and a long section 33 (Pig. 7), which form a sharp kink with one another.

The lengths of the short section and the

long section are e.g. 15 cm (or more generally 10 to 20 cm) or 35 cm (or more generally 30 to 50 cm).

The is in the working position

short section 32 in puss 18, and the long section extends backwards (Pig. 6).

Means are then provided for a

Pivoting the long section to the short section to prevent the rest of the skeleton. These means, embodied in any suitable manner, are e.g. Formed fixed or spring-loaded blocks, which are provided on the stem (or on the puss) and with the puss (or the stem) provided koiiplementaren grooves or holes cooperate.

To use the bag as a push cart,

109851/0166

2113206

- 9 - 3141-71

immediately in front of the user, the long section 33 in the P-uss 18 can be plugged in while the short section extends backwards.

Finally, for parking

the short or long section not inserted into the puss 18 is brought forward over the framework 16 (see the in Pig, 6 position shown in phantom).

This latter training can do less

be shapely than the previous one, but it is stronger, easier and easier to use.

In both Palls, the total height of the bag can be reduced for the parking position, that the pus 17 and 18 completely in their tubular Receiving spaces 2 and 3 can be pressed in or completely pulled out of these to the framework next to the pocket to turn off.

It should be noted that, due to the double horizontal bracing of the Legs 2 and 3 of the frame of the bag through the rod 15 and the frame 19 this frame is very solid and possibly. The User can serve as a support.

The accessibility of the above shopping bags for the goods to be conveyed is generally very good satisfactory. These goods are delivered through the openings between the rod 15 and the rods 36 (Pig. 9) delimiting the top of the two side walls of the pocket are inserted into the pocket or taken out of this, the rods in the open position 'of the pocket relatively far from the rod can be straddled.

However, it can be particularly bulky

Occasionally these openings for their passage are not big enough.

To remedy this disadvantage,

according to the modification of the Pig. 8 to 11 the rod made retractable.

It can then be temporarily removed

to improve the accessibility of the inner volume of the bag, after which it is returned to its normal position for carrying the bag.

109851/0166

- 10 - 3141-71

The retraction of the rod 15 can be accomplished by any desirable mechanism.

So can 25.B. that rod at one end

be pivotable on one of the legs 2 and 3 of the frame in particular about a horizontal axis, while on the other leg a receiving space provided with a locking system is provided for the other end of the rod.

However, this rod can also be complete

can be omitted, and their function can be fulfilled by the central sections of the rods 36, which extend laterally place against each other, at least one of these middle sections being widened for this purpose. However, this solution continues presupposes that the bag can always be closed by mutual approach of its two rods 36, what their filling limited.

In the illustrated embodiment, the rod 15 forms the apex of a bracket 37 in the form of a inverted U, the feet 38 and 39 of which are pivotable on the two legs 2 and 3 of the frame.

Purely this pivoting attachment can of course a simple design was also chosen, which only allows rotation of the bracket around a fixed axis of the frame, v / obei a manually operated locking system is provided on this to the bracket at will in its vertical position to be firmly connected to the frame.

In the preferred embodiment shown

w rungsforra a completely independently working mechanism for locking the bracket 37 is provided.

This mechanism comprises means 40 which, in spite of the pivotable attachment of the bracket 37 to the frame Allow small perpendicular displacements of the same when it is in the vicinity of its perpendicular position of rest fixed guide means 41 provided at the upper ends of the legs 2 and 3, which cooperate with the bends of the bracket, and springs 42, which pull the bracket 37 continuously upwards.

The means 40 comprise two arrangements

. With a block 43 and an elongated hole 44, each Block 43 on the bracket foot or the corresponding frame

leg is located and with one on the corresponding frame leg or an elongated hole 44 located at a U-shaped foot .

In the illustrated embodiment is

each block 43 (Pig 11) on a frame leg (2 or 3) attached, and each elongated hole 44 is worked out in a plate 45 firmly connected to a U-shaped foot (38 or 39).

The reverse arrangement can, however

can also be selected, each elongated hole then being through the opening of a vertical slot in one leg of the frame is formed and with · one at a puss of the temple fastened block cooperates, which can even be formed by a horizontally bent end of the bracket.

This spring 42 is, for example, a torsion coil spring which is located between a block 43 and an anchoring point 46 is stretched out on the edge of the corresponding elongated hole 44.

The guide means 41 comprise two ramps

47 (Pig x 10) and two stops 48, which are preferably formed by cut and bent plates, which on two rings 35 to plague the feet 17 and 18 in the Legs 2 and 3 are welded, with a ramp and a stop per ring are available.

The ramps 47 have such a shape,

that the bracket at the end of its approaching the vertical Rotational movement against it with the upper edges of its kinks and then pushing it downwards while sliding on these ramps to be led.

Each stop 48 is in one

horizontal distance from the opposite end of the ramp 47 arranged that there is just enough width between it and this end so that the. Kink of the corresponding Bar can pass perpendicularly with a little play.

This stop 48 is with respect to the ■

Ramp arranged so deep that the bend of the bracket hits it with a rotary movement at the end of its sliding movement, as can be seen from FIG.

The temple itself is proportionate through a formed thin curved rod, the the

109851/0166

- 12 - 3141-71

■ Bar 15 forming section of this bracket, which as a handle for carrying the bag is widened by attaching a tubular sleeve to this.

The above mechanism works as follows.

Assume that the bracket is too

The beginning is in its rest position, i.e. that it is in its vertical position shown in full extension in FIG is locked, the rod 15 allowing the bag to be carried on the arm.

To withdraw this rod it is enough

to press them down so that the elongated holes 44 perpendicularly along the blocks 43 against the return force of the springs 42 slide, and then turn the bracket in the direction of arrow F as soon as it has moved vertically so far that it from the adjacent ends of the ramps 47 comes free. Relaxation of the springs 42 can accelerate this rotation immediately after its initiation by the bracket on this Brings ramps 47 to slide.

The bracket can then have the lines dashed in FIG.

assume the withdrawn position shown in dotted lines, in which strikes the rod 15 on a side wall of the pocket in the open position.

The opening of the pocket is then the largest and can even let very bulky goods through.

\ '! hen the filling or emptying of the

ψ see is finished, it is sufficient to pivot the bracket 37 in the direction opposite to the arrow F. At the end of this decline it automatically slides on the ramp 47, whereupon it tensions the springs 42 anew, and the relaxation of the springs following this sliding movement automatically pulls the bracket back into its locking position shown in full extension in FIG.

Then you need to carry the bag

only to take the rod 15 in hand (and if necessary the middle ones Sections of the two rods 36 which are exposed for this purpose and are provided in such a way that they are in the Schliessungsstel-Iu ng the T ac before the side against the stalk !? put) what easy a positive touch between the lower end of a
