    FIELD OF THE INVENTION The present invention relates to a retaining arrangement according to the preamble of the independent claim.
    More specifically, the invention relates to a retaining arrangement for retaining batteries in a battery charger. The batteries and the holding arrangement can be arranged on a vehicle, e.g. a truck, a bus, a work vehicle, or a car. The arrangement can also be used for batteries that are arranged on a ship or in another place where they can be exposed to vibrations and therefore must be kept in place.
    Background to the invention Oga vibration levels affect the life of the batteries and it is very important that the batteries are selected in the battery charger or the place where the batteries are mounted. Today, the batteries are often mounted in their position and an overlying yoke gives a vertical compressive force on the upper side of the battery, thereby the batteries are firmly clamped in their position. ! Through the commercial vehicle side (truck), a yoke is mainly used which gives a vertical pressure on the battery and thus keeps it tapered in the right position.
    The vertical force from the yoke must be sufficiently high for the batteries to be stubbornly mounted, despite the fact that the vibration levels can be high, which can be especially the case when driving on a dangerous road. At the same time, a near vertical force can cause deformation and / or damage to the batteries. This deformation (or relaxation) of the outer shell of the battery causes the force from the yoke to decrease and the batteries can be displaced (slipped) at the bottom. The same problem arises when the clamping force from the yoke is too small in relation to the friction between the battery and the surface on which the batteries stand.
    This offset at the bottom of the batteries when the vehicle is subjected to vibrations also has a negative effect on the life of the batteries. This life reduction is especially noticeable if there are fixed stops or depressions where the batteries are to be placed, as the batteries can then slide between fixed stops and the forces that then arise (shock pulses) damage the batteries. At the same time, however, such a construction facilitates for the mechanics, because it is so clear where and how the batteries should be placed.
    Because the tolerances on the outer dimensions of the battery housing are so large, which is a global problem, and applies to batteries from all manufacturers, it is not possible to make fixed stops or depressions at the position where the batteries are to be placed with the exact fit. If these stops and / or depressions are constructed with some medium mat, some batteries will come loose and others will not be fitted.
    In the following, a number of patent documents are discussed which show different types of arrangements for holding batteries in place in a vehicle.
    W02012163832 shows a method for attaching batteries in a battery charger has a truck that must withstand high vibrations and not be dependent on the size of the battery charger. Two batteries are connected to a belt tensioning device which comprises a spring with an elastic rod which is pressed down between the batteries.
    WO201080058 discloses a method for clamping dual batteries comprising a clamping device disposed between the batteries. An expansion takes place of this towards the batteries which will be pressed against each other's breath stop.
    Both GB2015951 and US5040627 show arrangements with a battery charger with an overlying yoke where two batteries stand side by side on a bottom part and a rod is mounted between the batteries. GB2015951 also describes that the batteries are mounted to speak vibrations by the batteries being pressed against a frame.
    DE10216148 describes a device intended for a vehicle battery. The device comprises a fixed and an adjustable contact surface. Between the contact surfaces there is an elastically deformable member. The member is compressed when the distance between the contact surfaces decreases.
    Finally, US20080057393 discloses a battery module which is highly vibration resistant. With the help of an elastic part, any play can be reduced and thus the vibration sensitivity is reduced.
    The object of the present invention is to provide an improved fastening arrangement for batteries which works for batteries despite varying outer dimensions for the batteries, which ensures that the batteries are kept fixed both in the vertical and in the horizontal direction, and which allows easy handling.
    Summary of the Invention The above objects are achieved by the invention defined by the independent claim.
    Preferred embodiments are defined by the dependent claims.
    By using an expanding means that expands when mounting the yoke, the distance that defines the space where the batteries are to be mounted can be adjusted to the maximum outer mat for the batteries, which means that all batteries can be mounted. At the same time, the batteries (regardless of the type of tolerance) are pressed against their support members when the yoke is pulled and the risk of damage due to slipping between the support members is eliminated. The yoke should, for example, be fastened with 16 screws that are pulled towards a stop and in this way take advantage of the long screw's ability to maintain the torque / fastening properties even if the battery tolerances are relatively large / uncertain.
    The holding arrangement according to the invention eliminates the risk that the battery is not sufficiently clamped in the bottom and that the vertical force from the yoke can be optimized without affecting the risk of the batteries sliding in the bottom.

    Detailed Description of Preferred Embodiments of the Invention Referring to the figures, the invention will now be described in detail.
    In the figures, the same male designations have the same allants to denote the same or similar details.
    First with reference to Figures 1a and 1b which show the holding arrangement in a non-fixing condition and in a fixing condition, respectively.
    The invention thus relates to a holding arrangement 2 for holding at least two batteries 4 placed side by side. The batteries are preferably placed with the long sides facing each other.
    The arrangement comprises a substantially horizontal support surface 6 on which the batteries 4 are adapted to rest, the support surface is provided with substantially vertically directed support parts 8 having a predetermined vertical height. The support surface can, for example, be made of a flat sheet of a plastic material or of metal. The surface where the batteries are to rest is dangerously coated with a rubber mat or similar for the purpose of increasing the friction between the batteries and the support surface. In the figure, the vertically directed support parts 8 are shown as continuous, but they can also be divided into a number of shorter parts. The vertical height of the support members is of the order of a number of centimeters. As an alternative, the support surface can have a recess, in the form of a trough, where the support parts then form the cradles of the recess.
    The support parts 8 consist of two parallel opening parts which define a space between the parts where the at least two batteries 4 are adapted to be placed so that the support parts 8 run along outer sides of the two batteries 4.
    The retaining arrangement 2 comprises at least one fixing device 10, having a first fixing part 12 and a second fixing part 14, and which is adapted to be in a fixing state and in a non-fixing state. Since the fixing device 10 is in the fixing state, it is adapted to apply substantially vertical forces 16 on the batteries 4 via said first fixing part 12, the vertical forces 16 being adapted to press the batteries 4 against the support surface 6, and partly substantially horizontal forces 18 on the batteries 4 via said second fixing part 14, the horizontal forces 18 being adapted to press the batteries 4 against the support parts 8.
    With continued reference to Figure 1, the fixing device 10 comprises an elongate, substantially vertically directed rod 20 with an upper activating end 22 and a lower end 24 which is adapted to cooperate with said supporting surface 6. The upper activating end 22 may, for example, have the shape of a bolt head or be provided with a suitable socket for an Allen key or some other form which makes it possible to apply a rotational movement to the rod 20 via the byre actuating spirit 22.
    The fixing device 10 is adapted to be transferred from said non-fixing state to said fixing state by the action of said tivre activating end 22. Thus the holding of the battery is achieved with both horizontal forces and vertical forces by affecting only the byre activating spirit which facilitates mounting and fixing of the batteries.
    As can be seen from the figures, the rod 20 is adapted to be arranged between two batteries 4.
    The first fixing part 12 preferably comprises an elongate yoke which cooperates with said lower part of the rod 20, and which is adapted to apply substantially vertical forces 16 to the batteries 4, since the fixing device 10 is in the fixing state. The first fixing part 12 is preferably arranged at right angles to the longitudinal extent of the batteries. In Figure 3, where the arrangement is shown in a view from above, two fixing devices are arranged and the first fixing parts 12 have been indicated by line markings.
    The second fixing part 14 comprises an expansion means 26 arranged at the lower spirit 24 of the rod 20 and is adapted to transmit substantially horizontal forces 18 to the batteries 4, since the fixing device 10 is in the fixing state. The expansion means is adjacent to and acts against the lower parts of the batteries and has a vertical height which is in the same order of magnitude as the MO of the support parts. The horizontal forces exerted by the expansion agent against the respective batteries will thus be applied with the support members as abutment.
    The lower part of the rod cooperates with, and engages in, the support plate e.g. via a corridor in the plate.
    Figures 3a and 3b thus show a top view of the holding arrangement 2.
    In the figures, the distance between opposite support members 8 is denoted by A. In the non-fixing state, see Figure 3a, A is greater than 2B + D1, where 2B is the total width of two batteries 4 placed side by side and D1 is the horizontal width of the expansion means 26. The reason is, of course, that it should be possible to easily place the batteries in place and also place the fixing device between the batteries and fasten it to the support plate.
    Figure 3b shows the arrangement in the fixing state. The expansion element has c16 width D2 and War horizontal forces on the batteries (indicated by arrows). Figures 4a and 4b show the lower part of the fixing device with the expanding means 26. According to one embodiment, the expanding means 26 has an elastic cylinder which in the non-fixing state has the height h1 and the width d1 and in the fixing state has the height h2 and the width d2, where h2 < h1 and d2> dl. D1 and D2 are in the order of a number of cm, for example d1 is in the range 2-4 cm and d2 is in the range 3-6 cm. The flaids h1 and h2 are in the same order of magnitude as the vertical height of the districts, ie. in the order of 3-10 cm.
    Fixing device 10 further has a stop part 28, which in cooperation with a rigid cylinder 30, is adapted to indicate when the fixing device 10 is in the fixing state in that the cylinder prevents the stop part from going further down, and thus prevents them from popping on the batteries 4. vertical forces Exceeds a danger-determined value which has been determined with regard to the type and size of the bat, etc.
    The expansion means can be designed in a number of different ways where the selected construction should be able to transfer a vertical movement from the rod to horizontal forces.
    Figure 5 shows a sketch of a tankable construction consisting of a number of wedges where a vertical movement from the middle wedge is transferred to the wedges on anise sides. The resulting forces are indicated in the figure by arrows.
    Other conceivable constructions include different types of lane arrangements, spring arrangements, as well as pneumatic and hydraulic systems.
    Figures 2a and 2b show side views of the retaining arrangement. Figure 2a shows the arrangement in the non-fixing state and figure 2b shows it in the fixing state.
    In Figure 2a, the batteries have been placed on the support plate 6 and the fixing device has been applied by placing the rod 20 with the expanding means 14 between the batteries. The Over fixed part 20 has abutment parts for smooth cooperation with the batteries. By influencing, e.g. by rotating, the Upper actuating member 22 will on the one hand apply the Upper fixed part substantially horizontal forces to the batteries and on the other hand the expanding means 14 will expand in horizontal directions and thereby Overtake the batteries so that they are carried outwards towards the support parts 8 and Over * da to the condition shown in Figure 2b, i.e. the fixing state.
    The magnitude of the applied horizontal and vertical forces is, as mentioned above, dependent on, among other things, the type of boat in the grid, but also e.g. size.
    In the embodiments shown, the arrangement has been described for holding two batteries. Within the scope of the inventive concept as defined by the claims, it is also possible to arrange the arrangement for holding more than two batteries. The upper fixed part can then, for example, lap Over batteries placed side by side (if there are tie batteries to be held in place) and two fixing devices placed between the batteries.
    The present invention is not limited to the above-described preferred embodiments. Different alternatives, modifications and equivalents can be anyandas.
    The above embodiments are, therefore, not to be construed as limiting the scope of the invention as defined by the appended claims.
