    Technical field The present invention relates to the field of prams which can be coupled to another rolling object, for example another pram or pram for simultaneous driving.
    Background of the invention From the international document WO 2016/025690 A1, it is known that by means of coupling means two prams are connected to each other in order to advance these side by side or alternatively to disassemble them for individual performance. These coupling means are located on the chassis parts of the prams and are designed for mechanical coupling by means of one or more handles.
    Furthermore, similar coupling means for interconnecting prams side by side are previously known from the documents GB 2334010 which show a lateral quick coupling, US 6527294 which shows a snap device in the form of a clip, US5522121 shows a male-female coupling, US 4805938 shows a coupling device in the form of a screw clamp which is operated with a wing nut and US2014 / 0265258 which shows a connecting device for prams with intersecting chassis details. All these known documents show different types of mechanical devices for interconnection.
    Common to all these known coupling means for prams is that they are slow to activate and that they are slow to deactivate. For example, a maneuvering person must stop to connect or disconnect the trailers. Neither of these coupling means can be used together with other types of wheeled objects.
    Object of the invention The object of the present invention is to provide a coupling means between a wheeled pram and a wheeled object, which may primarily be a similar pram and secondly a van or a permobile, the coupling means can be quickly activated or deactivated between pram and object.
    SUMMARY OF THE INVENTION By the present invention as set forth in the independent patent claim, the above object is fulfilled in which said disadvantages have been eliminated. Suitable embodiments of the invention are set out in the dependent claims.
    The invention relates to a pram comprising chassis parts to which at least three wheels are connected for driving the pram on a surface. Thus, the stroller type may refer to a stroller, a stroller, a sulky or an exercise stroller. To the chassis parts are at least one handle and a number of support parts, for example seat, backrest, footrest, reclining surface, are connected for carrying a child. At least one chassis part on one side of the pram is provided with a coupling member comprising at least one magnet for coupling of one side of the pram said against one side of a similarly wheeled object for simultaneous performance on said surface. This object can be, for example, a second pram, a shopping cart for the purchase of food or a permobile. In addition, the other side of the pram can also be provided with a corresponding coupling member or an alternatively magnetically coupled coupling member in order to be able to connect the pram with two objects, i.e. an object on each side of the pram.
    In an embodiment of the invention, said magnet is constituted by a permanent magnet, for example a neodymium magnet.
    In an embodiment of the invention, said magnet is placed at the same vertical level relative to the substrate as a ferromagnetic coupling surface placed on the object, for example comprising cobalt, nickel or iron, when the pram and the object stand side by side on the substrate.
    In an embodiment of the invention, said object is provided with a magnet which attracts either said pram magnet or a ferromagnetic coupling surface placed on the pram, for example comprising cobalt, nickel or iron, placed at the same vertical level relative to the substrate as the magnet of the coupling member on the pram when the pram and the object stand side by side.
    In one embodiment of the invention, the object's magnet is of opposite polarity to the pram magnet.
    In an embodiment of the invention, in addition, a coupling member which is mechanical, for example a reading bar, is connected to a chassis part on one side of the pram and at the same time connected to a side of said object. This mechanical coupling member is either designed to be snapped over chassis parts on the pram part of the object or fastened together with a snap or eccentric read.
    In an embodiment of the invention, said object consists of a second pram.
    In one embodiment of the invention, the two prams are of the same design. This embodiment is particularly suitable for twin transports where the bed children have identical prams and where each pram has coupling means on both sides which coupling means are intended to cooperate with each other. Similarly, such prams are also suitable for triplets in that three pram sheets are interconnected.
    In an embodiment of the invention, at least one chassis part on the other side of the pram is provided with a coupling means comprising at least one magnet for connecting the other side of the pram to a side of a similarly wheeled object for simultaneous driving on said surface.
    In an embodiment of the invention, the chassis part on one side of the pram is provided with a second magnet for interconnecting the said side of the pram against a side of a similarly wheeled object for simultaneously advancing on said ground.
    In an embodiment of the invention, the chassis part on the other side of the pram is provided with at least one magnet for connecting the other side of the pram to a side of a similarly wheeled object for simultaneous driving on said surface.
    In an embodiment of the invention, the chassis part on the other side of the pram is provided with a second magnet for interconnecting the said other side of the pram against a side of a similarly wheeled object for simultaneous advancing on said ground.
    In one embodiment of the invention, the magnet is placed in or on a cylindrical magnetic holder which is enclosed by an axially displaceable sleeve. By such an embodiment, a shear movement between the magnetic surfaces is eliminated.
    In one embodiment, the magnet is placed in a recess which cooperates with a corresponding projecting part, i.e. as a male-female coupling with a magnet placed in one, the other or both parts. In one embodiment of the invention, the magnet is annular and the pram is provided with an axially movable pin which can be displaced through a hole imagneten and into a corresponding hole in the object and locked in this extended position. By such an embodiment a shear movement between the magnetic surfaces.
    In the case of magnetic action, said shear movement is a movement which can cause the magnet to lose its coupling effect, and with any of the above-mentioned embodiments such a movement is not possible.
    In an embodiment of the invention, the magnet is placed in or on a cylindrical magnetic holder for co-operation with a similarly cylindrical magnetic holder on the object of a mechanical cylindrical male-female co-operation in combination with a single-magnetic co-operation. This embodiment also eliminates a shear movement between the magnetic surfaces.
    By means of such a magnetic coupling a rapid coupling of the pram and the object is effected by only one approach to the magnetic field of the magnet. For a disconnect pram and objects only a separating jerk is needed.
    In the embodiments provided with a supplementary mechanical coupling, this must of course also be operated. In the first place, these additional mechanical couplings must be seen as safety features to avoid involuntary separating movements.
    Brief description of the drawings The invention will now be described in more detail with references in connection with the accompanying drawing figures. The drawing figures show only principle sketches intended to facilitate the understanding of the invention.
    Figure 1 schematically shows a bare carriage which can be connected to an object according to the invention.
    Figure 2 shows an exploded view in magnification from figure 1.
    Figure 3 shows a first embodiment of sliding locking of the magnet.
    Figure 4 shows a second embodiment of sliding locking of the magnet.
    Figure 5 shows two prams connected according to the invention.
    Description of the invention Figure 1 shows a pram 10 comprising chassis parts CD to which at least three wheels 1, 2, 3, are connected for driving the pram 10 on a base 4. To the chassis parts CD are at least one handle 5 and a number of support parts 6, 7, 8, for example a seat 6, a backrest 7, a footrest 8, a lying surface, are connected to the support of a child. At least one chassis part CD on one side of the pram 10 is provided with a coupling member 91 comprising at least one magnet M1 M2, M5, M3, for coupling said one side of the pram to a side of objects 15 similarly provided with wheels 11, 12, 13 for simultaneous travel mentioned figure 4. In figure 1, the object 15 has been illustrated with a second pram.
    An advantageous embodiment of the invention is that the pram on the other side is provided with a similarly opposite coupling member 92, which means that your prams can be connected together to be transported in width.
    Figure 2 shows in an exploded view the coupling means 91 of the pram 10 in more detail, where the magnet M1 is removed from a first magnetic housing 21 which in turn is connected to a chassis detail CD. The pram 10 is provided with a second magnetic housing 22 in which a second magnet M2 is placed. The two magnetic housings are located at a distance A from each other. Preferably 10 cm <A <50 cm. In the embodiment shown, an armrest 23 extends to the stroller between the first magnetic housing 21 and the second magnetic housing 22.
    The magnet M1 cooperates with a magnet M3 placed on the object 15. Instead of the magnet M3, the object may be provided with a ferromagnetic coupling surface, for example comprising cobalt, nickel or iron, which is placed at the same vertical level above the substrate as the magnet M1. In case the magnets M1 and M3 cooperate, these magnets are of opposite polarity. As can also be seen from the figure, the magnet M2 cooperates with a magnet M4 placed on the object 15 at a vertical level with the same horizontal position as the magnet M2. Correspondingly, the magnet M4 can be replaced by a ferromagnetic coupling surface, for example comprising cobalt, nickel or iron.
    A mechanical coupling member 24, for example a locking bar, is connected to a chassis part on one side of the pram and at the same time connected to a side of the object 15. As can be seen from the figure, the object is designed as an identical identical pram, whereby the mechanical coupling member 24 can be clamped over the armrest 23 on the first pram and over a corresponding armrest 25 on the second pram for mechanically coupling the first coupling means 91 with the same opposite coupling means 92 on the second pram. With this 6 mechanical coupling means 24 an additional securing of the coupling is thus provided.
    As also shown in Figure 2, the magnets are preferably provided with a center pin 26 intended to cooperate with a corresponding center recess 27 before controlling the interconnection between the magnets and to some extent preventing slippage between the magnetic surfaces.
    Figure 3 schematically shows a first embodiment of a sliding lock of the magnet M2 to prevent a sliding between the magnetic surfaces of the magnets M2 and M4. The magnet M2 of the pram 10 is provided with an enclosing sleeve 31 which is axially displaceable according to the double arrow in the figure so that in a slid-locked position the cover contact plane 32 between the magnetic surfaces is shown in the figure with dashed lines. In a non-sliding position, the sleeve is displaced away from the contact plane, which is shown in the figure with the sleeve in solid lines.
    The embodiments according to Figures 3-4 are particularly suitable for magnetic surfaces which are completely flat.
    The function is thus that when the pram's magnet M2 has been coupled to an object's magnet M4, the driver of the pram can choose to also lock the magnets by displacing the sleeve 31 over the contact plane 32 between the magnets. An opposite movement of the sleeve 31 releases the slide lock.
    Figure 4 schematically shows a second embodiment of a sliding lock of the magnet M1 to prevent a sliding between the magnetic surfaces of the magnet M1 and a corresponding magnetic surface of an object. In this embodiment, the magnet is formed with a center hole 41 through which a locking pin 42 is slidably mounted by being connected to an operating arm 43 with which the axial position of the locking pin relative to the magnet M1 can be adjusted according to the bidirectional arrow. In this embodiment, the magnet M1 at the retracted locking pin 42 is allowed to attract an object-corresponding perforated magnet, after which a sliding lock is provided by the actuating arm 43 displacing the locking pin 42 into the perforated magnet of the object. The magnet M1 in this embodiment is placed on a cylindrical magnet holder 44 inside which the locking pin 42 is axially movably mounted and can be displaced with the operating arm 43.
    Figure 5 shows the first pram 10 coupled to a second pram 50 according to the invention. The first pram is provided with a first coupling member 91 on one side thereof and with a second coupling member 92 on its other side. Similarly, the second stroller 50 is provided with a first coupling member 51 on one side thereof and a second coupling member 52 on the other side. Each pram coupling means 91, 92, 51, 52 are formed with two magnets which are placed at a distance A from each other as also indicated under figure 2. One side coupling means 91, 51 are formed with projecting magnets 93, 53 while the other side coupling means 92, 52 are formed with recessed magnets in cylindrical magnetic housings 94, 54. By projecting magnets cooperating with respective recessed magnets, a sliding lock is obtained between the magnetic surfaces. The placement of the magnets and their respective magnet housings is preferably done where the chassis parts of the prams have their folding joints which are activated when the prams are folded up and down. Even more, two prams can be connected.
    Figure 5 shows an interconnection of two prams of the sulky model, of course two or more identical prams of other pram types can be interconnected in the same way.
