Description

The invention relates to a trailer for a children's vehicle, which may be, for example, a tractor provided with pedals. The trailer can also be attached to a motorized children's vehicle.

A trailer of the type considered contains four stanchions at the corners of his cargo area, where side walls are attached. For example, the trailer can be loaded with bulk material, with the side panels preventing the trailer from losing its load.

In particular, the trailer may be a three-way tipper disclosed in the European patent 0723793 is disclosed. In this three-way tipper the loading area with the side walls forming a trough can be tilted in a threefold manner, namely around a transverse axis running transversely to the longitudinal axis of the trailer and around the two lateral longitudinal axes of the loading trough.

The present invention has for its object to provide a trailer for a children's vehicle, which offers a high play value for children. In this case, the loading trough of the trailer, that is, the arrangement of loading area, stanchions and side walls, preferably be tiltable about different axes.

This object is achieved by the features of claim 1.

Advantageous embodiments of the invention will become apparent from the dependent claims.

The invention provides that on each side of the loading surface two side walls are arranged one above the other, which are releasably secured in a special way. For this purpose, it is provided that on each side wall at the upper edge region two laterally projecting from the ship's side lugs are attached, have the central holes into each of which a displaceably attached to the associated Runge first latch is inserted, so that the side walls at its upper edge region detachably are hinged to the stanchions.

It is further provided that at the bottom of each side wall a plurality of spaced apart, movable second latch are arranged, and that these second bars of the upper side walls in sleeve-shaped projections on the upper edge of the lower side walls are inserted, while the second latch of the lower side walls in sleeve-shaped Approaches to edge profiles of the cargo bed can be inserted.

Thus, the lower edge regions of the side walls are not releasably attached to the stanchions, but the upper side walls are releasably articulated by means of the second latch on the upper edge region of the lower side walls, while the lower edge region of the lower side walls releasably articulated to below arranged edge profiles of the floor or the loading area are.

This training allows a child to place the trailer in a variety of different states, and this applies to all four sides of the trailer's cargo space:

1. 1. The upper latches of the two stanchions of one side are withdrawn from the substantially mushroom-shaped lugs of the upper side wall, whereby the upper side wall can be folded outwards around the latches located at the lower edge region in the locking position;
2. 2. The latches at the lower edge region of the upper side wall are moved into the release position, whereby the upper side wall is pivotable about the upper mushroom-shaped projections to the outside;
3. 3. The latches on the stanchions at the level of the upper edge region of the lower side wall are moved into the release position, and the lower latches on the upper side wall are also retracted to the release position, so that the lower side wall about the bolt arranged at its lower edge is pivotable outwards;
4. 4. The located at the bottom of the lower side wall bars are moved to the release position, after which the lower side wall is pivotable about its axis lying on the upper edge region to the outside;
5. 5. The four bars on the stanchions are moved to the release position, whereupon both side walls are pivotable together about the longitudinal axis extending at the lower edge of the lower side wall;
6. 6. The two lower bars of the stanchions and the bars at the lower edge region of the lower side wall are moved into the release position, whereupon both side walls are pivotable about the axis lying at the upper edge region of the upper side wall to the outside;
7. 7. The upper side wall is removed after release of the associated locks;
8. 8. The lower side wall is correspondingly removable and
9. 9. Both side walls are removed.

In this way, the child can adjust the condition of the trailer in many ways the respective game situation, whereby the technical understanding is promoted. For example, one or the other side wall can be put into a swing-out state when the loading trough of a tipping trailer is swung up so that objects or bulk goods located on the loading surface can slip off the loading surface without further manipulation and thus be unloaded.

The loading area, or the floor, the stanchions and the side walls in a preferred embodiment of the invention of a hard plastic. Only the axles carrying the wheels and the linkage together with the crank, with which the bottom of the bearing space can be raised and pivoted, should be made of metal.

In further details, it is proposed that all latches, both those which are displaceably arranged on the stanchions, and the latches arranged at the lower edge regions of the side walls, have bolts.

It is also proposed that the first latches arranged on the stanchions each have a displaceably arranged actuating element, from which the bolt protrudes in the direction of the associated attachment of the side wall, that the bolt passes through a substantially U-shaped or horseshoe-shaped guide element, in the opening of which Bolt is guided, and that the actuating element in the lateral distance from the bolt has a slot which is penetrated by a peg-shaped approach of Runge. Thus, the actuator is guided virtually without lateral play in the upper region by the bolt and in the lower region by the engagement of the peg-shaped projection of the stake in the slot of the actuating element. In the peg-shaped approach a screw is suitably screwed, which fastened by means of a voltage applied to the actuating element annular disc, the actuating element slidably on the stanchion.

From the actuating member is suitably from a handle, which may be formed by an integrally formed rectangular projecting wall portion.

It is further proposed that each lateral approach at the upper edge region of the side walls substantially has a mushroom shape with a narrower cylindrical portion and a radially wider disk-shaped head portion. At the stanchions are provided for receiving the mushroom-shaped projection with a lateral inlet opening provided wall portions which have such a distance from the U-shaped or horseshoe-shaped guide member that the head portion of the mushroom-shaped projection can enter into the intermediate space the stanchion forms a lateral stop for the disc-shaped head section, so that its bore is aligned with the pin of the actuating element.

The bolts of the second latch at the lower edge region of the side walls are expediently guided in elongated sleeves and connected to a laterally projecting handle, so that the bolts are easily actuated by a child. At a lateral end of the elongated sleeve are mounted according to a further proposal of the invention in each case two spaced apart transverse walls, which have a matching with the length of the associated sleeve-shaped projection of the lower side wall or the lower edge profile of the bottom wall of the cargo space substantially matching, wherein in the Transverse walls holes for the passage of the associated bolts are formed.

The releasable locking means are designed so that they are easily operated even by small children without risk of injury.

It can not only be dismantled all side walls, but also the stanchions, which are plugged into recesses of the bottom wall and releasably lockable.

• FIGS. 13 to 17 enlarged representations of the corner of the loader attachment of the trailer and
• FIG. 18 an enlarged view of the upper part of a stanchion with locking devices.

FIG. 1 shows a three-axle trailer, the loading attachment 1 is tiltable about a rear, transverse to the longitudinal axis of the trailer axis. The tilt mechanism corresponds to that of the European patent EP0723793 ,

The loading attachment 1 consists of a bottom surface forming the cargo area 2, at the four corners of stanchions 3 are fixed, which are inserted into recesses of the bottom wall 2 and releasably locked in this position. At the stanchions 3, a lower side wall 4 and an upper side wall 5 are releasably attached to each side of the charge attachment 1.

FIG. 2 shows the charging cap 1 in a tilted by the front longitudinal axis in the figure state, while the charging cap 1 according to FIG. 3 about the other lateral longitudinal axis is tilted.

It will now be on the FIGS. 13 to 18 Referenced.

At the stanchions 3, four first locking elements 8 are each slidably mounted in the horizontal direction on the outwardly facing sides 6 and 7. The locking elements 8 contain - as in particular FIG. 18 clearly shows - a protruding bolt 9, which passes through a horseshoe-shaped guide member 10 that is fixed to the stanchion 3. In the lateral distance from the horseshoe-shaped guide element 10 are parallel to this projecting from the stanchion 3 two wall sections 11, between which an inlet opening 12 remains.

Obliquely offset from the perpendicular protruding from the stanchion 3 horseshoe-shaped guide element 10, a pin 13 is integrally formed on the stanchion 3, which also protrudes at right angles from the stanchion 3.

The locking element 8 also includes a right angle projecting from the front wall portion 14, which serves as a handle for moving the locking element 8.

The locking member 8 is slidably mounted on the stanchion 3 in the horizontal direction, that the bolt 9, the opening of the horseshoe-shaped Passing through the guide element 10, wherein the pin 13 passes through a slot 15 in the locking element 8. A screw 16 is screwed in the mounted state of the locking element 8 in a central bore of the pin 13 and holds the locking element 8 by means of an attached annular disc 17th

In particular FIG. 16 shows, standing on the upper edge region of the upper side wall 5 and the lower side wall 4 right and left depending on a mushroom-shaped projection 18 from the side edge of the side wall. The mushroom-shaped projections 18 each have a relatively narrow cylindrical base portion 19 and a wider disk-shaped head portion 20.

The upper side walls 5 and the lower side walls 4 are articulated with their upper edge portions in the manner of the stanchions 3 that the mushroom-shaped projections 18 are inserted with its narrower cylindrical portion 19 in the opening 12, such that the disc-shaped head portions 20 in the Gap between the horseshoe-shaped guide member 10 and the wall portions 11 occur. In this state, the locking elements 8 are initially withdrawn. When the locking elements are moved in the direction of the lugs 18, the bolts 9 enter the central bores 21 of the lugs 18, whereby the upper side walls 5 and the lower side walls 4 are releasably articulated to the stanchions.

FIG. 16 shows the state in which the left upper side wall 5 is released by the locking element 8 is displaced in the direction of arrow 22. In this way, the upper side wall 5 can be pivoted to the outside at the lower end of the side wall 5 arranged second locking elements 23.

The second locking elements 23 include at the bottom of the upper side walls 5 and the lower side walls 4 three or two spaced bolts 24, which are connected to laterally projecting handle portions 25 and guided in elongated sleeves 26. To the sleeves 26, two transverse walls 27 connect, which have such a distance from each other, that in each case a sleeve 28 can enter into the space between the walls 27. The walls 27 have holes that are aligned with the sliding pin 24 and the bore of the sleeve 28.

FIG. 17 shows the arrows 29, the state in which the bolts 25 are moved to the release position in which the lower side wall 4 can be expanded with their sleeves 28. In this case, the locking element 8 has been previously moved to the right to release the lugs 18 at the upper edge of the lower side wall 4, as already described above.
