    Both linear telescopic movement and rotating hinge movement which can be perceived as cumbersome for the user.
    The main object of the invention is thus to offer an alternative solution to a telescopically extendable shoehorn which instead rotates the extension elements, i.e. the arms, and then integrates the guide part and shaft of the shoehorn so that uniform joints can be used for the entire shoehorn. An important advantage of the rotating arms of the invention instead of telescopic arms is that the arms can be dimensioned uniformly, which reduces the cost, weight and volume of the shoehorn.
    DESCRIPTION OF THE INVENTION; The above object is achieved by means of an extendable shoehorn for a shoehorn comprising the features defined in claim 1. By providing an extendable shoehorn for placing between a user's heel and a heel part of a shoe, said shoehorn comprising a plurality of elongate shoehorns. arms which are articulated in relation to each other and articulated by means of holding elements, characterized in that said holding elements are arranged in the area at the respective end of the elongate arms so that relative rotation between the arms is allowed.
    Preferred features of the invention are defined in the dependent claims.
    Preferably, the elongated arms are flat so that each elongated arm has wide sides, long sides, and short sides. Advantageously, the elongate arms (2, 3, 4) are folded wide side to wide side in the folded state.
    Suitably the extendable shoehorn comprises at least stabilizing arrangements to counteract the rotational movement between the elongate arms.
    Advantageously, the stabilizing arrangement interconnects the elongated arms in the folded state and in the extended state.
    Suitably one of the plurality of elongate arms comprises a guide member.
    Advantageously, the stabilization arrangement is pressure fits. Press fits can work so that a protruding element with a predetermined force is positioned in a cavity which corresponds to the protruding element but is slightly smaller so that an elastic deformation of one or both constituent elements and keeps them in place relative to each other.
    Suitably, performed arm rotation provides an extended condition in which the elongated arms are positioned offset by at least one arm wall thickness relative to each other.
    Advantageously, the elongated arms share planes with the surface of the wide sides.
    Suitably the retaining elements consist of hinge joints.
    DESCRIPTION OF THE FIGURES: The invention will now be described in more detail with reference to the drawings, in which: Figure 1 shows a side view of a shoehorn which is fully folded, which has been formed according to an embodiment of the invention, Figure 2 shows a view obliquely from above of an elongated arm according to Figure 1, certain details having been omitted for the sake of clarity, Figure 3 shows a top view of a fully elongated shoe horn according to Figure 1, Figure 4 shows a cut-away view along the line II-II in Figure 3, Figure 5 shows a side view of a shoe horn which is fully folded, which has been formed according to an embodiment of the invention, figure 6 shows a view of the underside of an elongated shoe horn according to figure 5, to clarify the position of the holding element, figure 7 shows a side view according to the embodiment in figure 6, PREFERRED EMBODIMENT; Figures 1 to 4 show an elongate shoe horn (1) in which elongate arms are articulated for relative rotation with the holding elements (5) in the form of, for example, a rivet (5). The elongated arms (2, 3, 4) are two or more, advantageously three elongated arms are used so that in the folded state, according to figure 1, they have a mutual length of about 20 cm and in the case of an extended state, 50 cm. according to Figure 2, a total length of about 10 In order for the extendable shoe horn (1) to be held together in its folded and extended condition, respectively, it suitably comprises a stabilizing arrangement (6, 7, 11, 12). This aims to increase in a controlled manner the frictional resistance of the relative rotation of the arms (9, 13) when the arms share the same longitudinal direction, this takes place between the arms on a local surface between them until said friction is overcome by the shoehorn user. Said stabilizing arrangement (6, 7, 11, 12) comprises at least one recess or a hole in an elongate arm (2, 3, 4), and at least one protruding element (6) in an adjacent elongate arm (2, 3, 4). ).
    The elongate arms (2, 3, 4) are elastically bendable so that relative movement between the elongate arms about the axis of rotation of the retaining elements (5, 10) creates a press fit between recess (7) or holes on an elongated arm and corresponding protruding elements ( 6) on the adjacent elongated arm.
    The protruding elements (6) are spherically shaped and (7), are larger than 0.1 mm relative to the wide side surface (20), the recess or the hole, are round. Protruding elements (6) (l5). An arcuate guide groove according to Figure 3 is located on at least one elongate arm (2, 3, 4), said guide groove (20) being positioned between recesses (15) (7) or holes on (17). (7), the surface of the wide side and its edge to the long side (20) leading to the recess (6), only a part of the protruding elements is absorbed by the guide groove substantially narrower than the protruding elements so that the guide groove (20) in its rotating movement ending in press fit with the recess (7). The guide part (14) on elongate arm (2, 3, 4) has a concave wide side (15), which is not shown in the figures. A concave wide side (15) more easily follows the shape of the heel.
    The elongated arms (2, 3, 4) advantageously consist of materials such as plastic, wood or metal, and combinations in between.
    Figures 5 to 7 show an extendable shoehorn (1) which shares features with the description made to Figures 1 to 4, and only the differences will be mentioned.
    A rotating movement (13) according to Figure 5 gives an elongated condition where the elongated arms (2, 3, 4) (15), share planes with the surface of the wide sides according to Figure 7. The rotation (13) can be compared in the same way as e.g. paper that is folded in the middle then folds out to its full area, and vice VGISÛ. .
    The retaining elements are hinged (10), mounted separately to the elongated arms or integrated with the elongated arms. Advantageously, it is cast in a continuous piece where the elongated arms are held together by areas of reduced wall thickness (8) so that a hinge function is achieved.
    The protruding elements (6) and the recess (7) are suitably rectangular in shape.
    Figure 6 shows reinforcing ribs (19) which reinforce the elongated arms (2, 3, 4), said reinforcing ribs (19) forming recesses (12) which together with the protruding elements (11) form a press fit when the shoe horn (1) is extended. ).
