The trailer connection 1 which in the direction of the arrow 41 by pushing in FIGS. 1 and 2 is a so-called stroller with a manually propelled vehicle 2 for carrying children, a frame 4 and a fixed rear axle 5 Only the lower part and the handle 3 are shown), there is a person / commodity load receiver 6 of a trailer 7 on the rear shaft 5, the frame constitutes a handle, and the load receiver is uniaxial by elastic rods. Is fixed to the frame. Cargo receiving 6
Has a substantially triangular shape, and is provided with casters 11 near the middle portion 10 of the rear portion 9 and is supported. The fork 12 is mounted so as to rotate by a vertical shaft 13 and is inclined forward and downward with an inclination a of about 3 to 15 °, preferably 5 to 10 °. Due to the ergonomic structure of the rear part 9, the rear end of the trailer 7 has little obstruction to the forward movement of the person pushing the trailer connection. The feet 14 move adjacent to and / or below the load receiver, adjacent to both sides of the casters 11, and do not hit one foot against the load receiver. The user can hold the handle without bending forward more than necessary. Elastic rod 8 (
A portion adjacent to the rear portion 9 of the load receiver 6 in the track width m of the movable portion n of the movable portion n of a coupling means described in a modification described later is a space so that the shin of a person pushing the connecting body does not hit. . The load receiver can carry a second child or other load in an upright position, or can be a substantially triangular container or child seat.

The width “b” of the trailer 7 is small at the portion where the casters 11 are supported on the ground, and is preferably smaller than the width “c” between both feet 14.

In the upper storage position in which the trailer 7 is stored by the shaft,
2 or the handle 3 or other elements of the manually propelled vehicle 2.

FIGS. 3 and 4 of the trailer connection have a connection means 16 consisting of a mounting arm 18 fixedly mounted on a rear leg 17. The trailer 7 is mounted on an arm 18 on a horizontal shaft 19. The shaft 19 is located slightly behind the vertical axis at the position where the rear wheel 20 of the manually propelled vehicle 2 is in contact with the ground, and this position e and the position e so as not to obstruct raising the rear wheel 20 of the manually propelled vehicle 2 to the back. Preferably not earlier. The trailer 7 folded upward is firmly fixed to the container 32 by the elastic return 21.

The trailer connection of FIGS. 5 to 9 is connected to the rear leg 17 of the manually propelled vehicle 2, which is an embodiment of a folding child stroller. All the frame elements can be moved and folded laterally, the front leg and the rear leg move laterally with respect to each other, FIG.
The folded state shown in FIG. The trailer is still mounted by the connecting means 16 in this case. The connecting means 16 includes a mounting arm 23 fixed to each rear leg 17 by a clamp 24 and a V
And a mold spring 25. The spring 25 has a hook 29 at each of its outwardly facing ends 26 and is disposed through a horizontal slot 27 in the front end 28 of the triangular load receiver 6. The hook 29 is a keyhole 30 of the mounting arm 23.
By passing through, both are fitted and connected. The bolt 31 protrudes through the rear part of the load receiver 6 and screwes the fork 12 and the spring 25 together. By compressing the ends 26 together, the hook 29 can be removed from the keyhole 30 and the trailer can be removed. The manually propelled vehicle 2 can then be folded.

In the variant of FIGS. 10 and 11, the respective (at least one in each case) mounting arm 23 is firmly mounted on the rear leg 17 and faces each other (FIG. 10) or turns away from each other (FIG. 10). 11) It is composed of a spring that is tensioned as described above. These hooks are pin-shaped ends 3
3 is pivoted through the holes in the ears 34 of the load receiver 6 and removed by elastically bending the mounting arms apart.

In FIG. 11, the cargo receiver 6 has a triangular shape with the rear corner 50 turned to the right, and both feet of the user are located on the same side with respect to the wheels 11 without obstruction. become.

The cargo receiver 6 of FIG. 12 has a hook 29 at each front corner for coupling into the keyhole 30 of the mounting arm 23. At least one hook 29 is attached to a resilient lip 36.

It is preferable that the loading tray 6 has a rough surface. (FIG. 14)
In addition, the load receiver may be constituted by a collapsible platform, for example such that two strips 37 are supported on one another by bolts 31 and a cloth 38 is stuck between them. (FIGS. 15 to 17). The cargo receivers 6 shown in FIGS. 18 to 20 are connected to each other by hinges 39, crosses 38, or the like.
The cargo receiver 6 is permanently attached to the manually propelled vehicle 2 or not, and is located in the folded state in FIG.

The trailer 7 in FIG. 21 does not have a triangular shape, and is additionally connected to a mounting arm 23 of the folding manual propulsion vehicle in FIG. 6 by a W-shaped spring 25 and a hook 29. The cargo receiver 6 has a recess 51 at the center of the rear end, which does not extend beyond both sides of the center. The casters 11 are mounted on two rear corners 50.

When used in a baby stroller as a manually propelled vehicle 2, the load receiving caster 1
The horizontal position from the point supported by 1 to the position fixed to the manually propelled vehicle is between 100 and 20 cm, preferably between 80 and 30 cm, more preferably between 70 and 40 cm. The width b of the load receiver at the position where the casters 11 are provided is between 50 and 10 cm, preferably between 40 and 15 cm, more preferably between 30 and 20 cm. The width k at the front end of the triangular base of the cargo
5 cm, preferably between 60 and 30 cm, more preferably between 50 and 35 cm. The height h of the cargo receiver 6 is 40 to 5 cm, preferably 30 to 10 cm
, More preferably between 25 and 15 cm.

The baby carriage is lightweight, for example between 20 kg and 5 kg, and the weight of the trailer 7 according to the invention is between 10 and 2 kg, preferably between 5 and 2 kg,
More preferably between 3 and 2 kg.

As described above for the connector 1, the cargo receiver 6 of the trailer 7 is
, And more preferably, the space m which jumps up due to the trajectory of the movable part n of the support for attaching the trailer 7 to the manually propelled vehicle 2.
And at least part of the rear part of the load receiver 6 is preferably left as space for at least one shin of the person pushing the trailer.

As shown in FIGS. 10 and 11, respectively, the blocking means 45 are attached to each or at least one mounting arm 23, for example if the trailer 7
If the standing child pulls the manually propelled vehicle 2 towards him, the ear 34 will move opposite the blocking means 45. For example, when the infant is sleeping, it is prevented from being folded back to the rear of the manually propelled vehicle 2.

Such a blocking device may be present in yet other embodiments of the figures.

In FIGS. 4 to 9 the blocking means 45 is fixedly mounted on the mounting arm 23 and is connected to the lower part of the projecting end 47 of the spring 25. In order to pivot the trailer 7 uniaxially behind the manually propelled vehicle 2, the springs 25 have their respective resilient mounting arms slightly displaced in the direction of movement of the springs and become disengaged and hooks 29 with the blocking means 45. Respectively, and jumps uniaxially upward to the pins 33 respectively.
