Description

The invention relates to a rollable transport vehicle according to the one-part patent claim 1.

From the DE 10 2009 015 788 A1 already a rollable trolley is known. This dolly has a chassis in accordance with the invention. On the chassis two wheels are attached. In the chassis, a container can be used. The trolley can be hung and locked in a receptacle on a trailer hitch of a motor vehicle.

From the DE 10 2011 000 021 A1 is a rollable walker known.

From the DE 197 33 615 A1 is a rollable trolley known, can be used in the several containers, taken out and fixed and locked.

The DE 10 2011 010 154 A1 relates to a trolley with a chassis in which two platforms are arranged at different heights.

The object of the invention is to provide a rollable trolley, which allows a modular design in a variety of combinations and is particularly useful when shopping.

This object is achieved with the features of claim 1.

The rollable trolley has a wheeled chassis to which a front panel is attached. This front panel may for example be associated with a module carrier. In the front panel different containers are suspended one above the other in a particularly advantageous manner. Moreover, the containers are lockable relative to the front panel. For this purpose, a locking slide is provided. The front plate thus has a plurality of first coupling halves for suspending the container. The containers have matching second coupling halves. In addition, the front panel has a plurality of locking recesses into which locking parts of the containers can be inserted. The two coupling halves are separable from each other in the insertion position and hooked into each other in the holding position.

For locking the locking slide is guided in a locked position and, alternatively, displaceable in a release position. In the locked position, the second locking part is positively locked with the first locking part.

In a particularly advantageous manner, the two locking parts are lockable by means of a lock in the locked position. This prevents unauthorized stealing of the container from the front panel. For example, the locking slide may have openings through which a commercially available padlock or a brake disc lock is pushed through. This prevents that the locking slide is moved from the locked position to the release position. In order to prevent the theft of the entire trolley, this may have in a particularly advantageous manner completely enclosed openings through which a commercially available bicycle lock -. U-lock or folding lock - can be plugged and attached to a fixed bracket - e.g. a bicycle stand - can be attached. Instead of a bicycle lock, a safety line, a chain or a steel cable with a padlock can be used.

The front panel can be connected directly to the chassis. It is also possible that the front panel is part of a module carrier, which is connected to the chassis. The front panel thus establishes the central connection between the chassis and the containers. The combination of two coupling halves and locking mechanism creates a secure connection. It prevents the containers from inadvertently coming loose. The containers are securely connected to the front panel. In a particularly advantageous embodiment of the invention, the lock can be designed so that it is also used to securely close the container. As a result, the containers can be opened and / or removed only after unlocking.

The first locking part, which is arranged on the container, can for example be designed as a securing tab. This is particularly advantageous in containers with moving parts, as is the case with drawers, for example. In this case, the securing tab may be provided on the movable part. The locking tab is thus also used to lock the moving parts. By locking in the locked position thus results in theft protection. Instead of a securing tab, other embodiments of the second locking part are conceivable. For example, an eyelet or a T-shaped hook can be provided behind which engage corresponding parts of the locking slide. The containers are provided with carrying handles so that they can be worn individually. The containers have no right-angled corners and edges inside, so that easier cleaning is possible. For example, fillets are provided instead of corners and edges.

The containers can consist of antibacterial material in a particularly advantageous manner.

The containers can be designed in a particularly advantageous manner as a thermal container. These thermo containers are possible as independent constructions or as standard containers with a thermo insert. The containers may include details such as hooks and handles.

The uppermost container can be designed as a top case that can be opened from the top with a flap.

The foremost wheel 3 is for steering around a vertical axis 5 swiveling against the chassis 2 , The two rear wheels 4 are rotatable about a common horizontal geometric axis 17 , This horizontal axis 17 is stationary against the chassis 2 , On the chassis 2 is a module carrier 13 motion-proof coupled. These module carriers 13 extends away from the chassis 2 vertically upwards. The module carrier 13 has an in 4 as an item visible front panel 18 on, in the two different containers 10 . 12 are hung.

In 2 are the two containers 10 . 12 on the back wall 19 . 20 shown stylized. To attach the two containers 10 . 12 at the back wall 19 . 20 mushroom-shaped pin on which a first coupling half 9 form, which the respective container 10 . 12 with the front panel 18 combines. The mushroom-shaped pins are in keyhole-shaped recesses of the front panel 18 hooked. This keyhole-shaped recesses thus form a second coupling half 7 ,

There are two mushroom-shaped pins horizontally adjacent. To the container 10 respectively. 12 Mount each of the two pins in an upper large circular recessed area 21 the keyhole-shaped recess inserted. The container 10 respectively. 12 is in the insertion position, which is an upper position of the container 10 respectively. 12 is and graphic in 2 not shown.

Afterwards, the pins can be turned into an in 2 shown lower position moved or mounted. This lower position is the holding position. It attack mushroom heads 23 the two horizontally adjacent mushroom-shaped pins behind the respective tapered portions 24 the keyhole-shaped recesses. Each of the two upper keyhole-shaped recesses is followed by a row of seven further keyhole-shaped recess down. Here is the upper container 10 sure by means of four pins 9 in the module carrier 13 hooked. This upper container 10 of which only the back wall 19 in 2 is shown at one of both horizontally and vertically between these four pins 9 lying area a locking part 14 on, as a perforated securing tab 75 is executed. This security tab 75 engages in a corresponding locking recess 26 the front panel 18 one. This locking recess 26 is designed as a short rectangle cutout. There are four such short rectangular cutouts on the front panel 18 arranged one below the other.

From the back walls 19 . 20 seen from behind the front panel 18 is a locking slide 6 provided that over a top edge 44 the front panel 18 and a supernatant 25 a back plate 37 of the module carrier 13 stands out. The locking slide 6 is between the front panel 18 and the in 3 apparent back plate 37 vertically slidably guided up and down.

The back plate 37 has three parallel cutouts 38 . 39 . 40 on. The middle cutout 40 guides the locking slide 6 and has upper stops 36 and lower stops 41 for tabs 35 of the locking slide 6 on. These tabs 35 are in 2 seen. The two lateral cutouts 38 . 39 lead the mushroom heads 23 , These become as well as two spring supports 42 . 43 explained in more detail below. The back plate 37 also has the tongue-shaped projection 25 on that with holes 45 is provided.

The locking slide 6 is in 5 as an individual part and has several window-shaped rectangular cutouts 22 which extend vertically lengthwise. These window-shaped long rectangular cutouts 22 are just as wide and twice as high as the short rectangular cutouts in the module carrier 13 , In the long rectangular cutouts 22 bolts extend vertically. These bolts are resistant to movement on the locking slide 6 arranged and form a second locking part 15 for the first locking part 14 - ie, the securing tab 75 , The bolts close at the top rounded. The bolts extend from the lower edge of the window 27 until something over the middle of the long rectangular cutouts 22 ,

In synopsis with 2 and 4 It can be seen that the bolts release the short rectangular cutout, provided the locking slide 6 located in a lower release position. Will the locking slide 6 as shown in 2 shifted into the locked position, the bolt extends over the entire height of the short rectangular cutouts. Located in this short rectangle cutout at the same time from the back wall 19 respectively. 20 a container 10 respectively. 12 rearward perforated locking tab 75 a container 10 respectively. 12 , so these two locking parts are locked against each other. The bolt protrudes through a hole 72 in the safety tab 75 which the first locking part 14 forms. Now somebody tries the container 10 respectively. 12 in the locked position to lift up, so are the mushroom heads 23 from the rejuvenated area 24 excavated. However, the security tab beats 75 at the top edge 28 of the short rectangle cutout and can not be excavated.

In this locked position is the locking slide 6 continue over the top edge 25 of the module carrier 13 out than in the release position. In the locked position of the locking slide 6 of two helical compression springs 29 pressed, which at the bottom of the locking slide 6 in recesses 31 . 32 are recorded, which are open at the bottom. The helical compression springs 29 on the one hand locking slide 6 in the bottom region of the respective recess 31 . 32 from. On the other hand, the helical compression springs are based 29 at the spring supports 42 . 43 the back plate 37 from.

To the displacement of the locking slide 6 due to the spring force of the preloaded helical compression springs 29 to limit, are at the lock slider 6 the tabs 35 provided in the locked position at the stops 36 the back plate 37 come to the concern.

Is the locking slide 6 in the locked position due to the spring force of the preloaded helical compression springs 29 continue over the top edge 25 of the module carrier 13 out, so are two lower holes 33 of the locking slide 6 in flight with the holes 45 brought the supernatant. This can be in the locked position, a padlock 71 through the one hole pair 33 / 45 or both pairs of holes 33 / 45 be hung. This is the locking slide 6 completed in the locked position.

Above the lower holes 33 are in the lock slider 6 upper holes 34 provided in the padlock 71 can be hung when the upper holes in the release position in alignment with the holes 45 of the supernatant 25 are. This is the locking slide 6 completed in the release order.

It is also possible to have a cable lock through the hole pair 33 / 45 to pull and secured with this cable lock the trolley secured against theft on a bicycle stand, a lantern or other stationary object.
