    The present invention relates to a bag, in particular a suitcase, with a space-forming frame provided with at least two wheels, which are arranged in recesses opening in the frame towards the base, which wheels are provided with wheel transfer means for moving at least two wheels relative to the frame. Typically, bags such as those mentioned above are pulled from the pull handle on the top of the bag by means of wheels attached to the lower part of the body. Typically, there are two wheels. The user of the bag most often then walks in front of the bag, pulling the bag after him so that it is tilted in its direction (towards the user), typically about 10-50 °. Bags with transfer means are typically bags in which the wheels are moved inside the space bounded by the bag body - a “storage space” or “carrying space” where the bag can be stored or only carried, or a “use space” where the wheels are completely or partially in the space bounded by the frame. for the above use. Such bags are known, for example, from US 6289554 B1, US 4979598A, US 4852705A and US 4254850A.
    - The problem with the bags according to the above publications is that the ground clearance between the bottom of the bag body and the base is relatively small. Such bags are only intended to be moved on flat platforms, for example on the floors of transport stations such as airports and train stations or hotels. These are not intended to be moved on wheels on uneven surfaces which are not allowed by a small ground clearance, at least without difficulty in movement.
    In addition, PCT / KR2010 / 001607 (WO 2010/107219) discloses a bag with two pairs of wheels or the like, in which a pair of wheels with a smaller diameter are arranged under the bag for movement on a flat surface. A pair of wheels is arranged on the 30 side of the bag I, the wheels of which have a considerably larger diameter> than the wheels with a smaller diameter. A separate gluing mechanism is provided in connection with these wheels, in which the wheels in question are slid in a linear movement into the lowered operating position and the raised "storage position". This separate N-binding mechanism is relatively clumsy and heavy-structured, for which the so-called concealed walls, which in turn place restrictions on the volume and external dimensions of the bag. In addition to this, the mechanism appears to be structured in such a way that it generally receives forces in the direction of linear motion. This is disadvantageous for this separate binding mechanism, in which considerable transverse forces with respect to the linear movement are also generated when the bag is moved. These transverse forces and their effect on the durability of the structure have not been sufficiently taken into account in this structure. In addition to this, the mechanism always requires manual operations and positioning of the bag in a vertical position to move the movable wheels between different positions.
    The object of the present invention is to provide a wheel support with a simple structure which minimizes the interior space of the bag and increases the external dimensions as little as possible, in which the wheels are movable. At the same time, the purpose is to improve the usability (mobility) of the bag on different platforms by providing a variable ground clearance between the bottom edge of the bag and the platform. It is also intended to provide a structure in which the wheels are moved with simpler functions.
    This above-mentioned object is achieved by the features of claim 1, wherein: the wheel transfer means comprises: an elongate connecting piece of two wheels adapted to pivot about its longitudinal pivot axis in connection with the base of the frame; pivots arranged at the ends of the connecting piece which pivot with the connecting piece and comprising mounting axes arranged radially at a distance from the pivot axis coaxially with respect to each other, to which the wheels are rotatably mounted and whose common pivots formed by the mounting shafts are arranged to pivot about includes locking means between the first pivoting means and the frame for locking the first pivoting means in at least two different operating positions of the at least two wheels movable relative to the frame, the distances between the at least two different operating positions being different from the base and the lower edge. With the arrangement according to the invention, a bag is achieved with simple wheel transfer means 3, the two wheels of which can be easily moved simultaneously between at least two operating positions α. Of these, the first operating position is the so-called normal operating position that can be used on level surfaces (floors, roads in good condition). The second operating position is the so-called lowered operating position, in which the wheels are lowered relative to the frame so that the bag can be supported on the same wheels on much more uneven (most difficult) platforms (dirt roads, lawn, cobblestone) The construction of the transfer means also allows the locking means to be arranged in a manner inventive only in connection with the second wheel, since the operation of the locking means is transmitted via the connecting piece to the opposite wheel. This further simplifies the structure so that the disadvantages of the prior art presented above are avoided or significantly reduced.
    Preferred embodiments of the invention are set out in the dependent claims. They present preferred embodiments for facilitating the use of the movable wheels and the structural features associated with locking them in each position of use, which further improve the usability and durability of the structure.
    The invention will now be described in more detail with reference to the drawings showing a preferred embodiment of the invention, in which: Figure 1 shows an axonometric view of a bag according to a preferred embodiment of the invention in wheels in a first position of use; Figure 2 shows a bag of Figure 1 in a second position of use; Figure 3 shows an exploded view; Fig. 4 shows a side view of the structure of the transfer means and locking means according to the invention in the first operating position,
    O I 30 - Fig. 5 shows the side structure of the transfer means and locking means according to the invention in a second operating position, and = O Fig. 6 shows in more detail the structure of the transfer means shown in Fig. 3. OF
    Figures 1 and 2 show an overview of a bag 1 according to a preferred embodiment of the invention. The bag 1 comprises a body 1a, the cavity delimited by which forms a space for goods, such as luggage. The frame can be opened and closed in a known manner so that the goods can be placed in the space. The upper part of the body 1a is provided with a puller H, the height of which with respect to the body 1a can advantageously be varied, e.g. by a telescopic puller structure known per se. The bag 1 comprises at least two wheels 2a and 2b arranged in connection with the frame 1a as described below. In Fig. 1, the wheels 2a and 2b are in their first operating position, in which a normal distance D1 is left between the substantially flat base B and the lower edge 1b of the body 1a. Preferably, the normal distance D1 is about 1 to 5 cm. In Fig. 2, the wheels 2a and 2b are in their second operating position, in which an increased distance D2 is left between the uneven base B 'and the lower edge 1b of the body 1a. Preferably, the increased distance D2 is about 5.5 to 12 cm, more preferably 8 to 11 cm. This is such an increased distance (ground clearance) which still allows the wheel transfer means as described below in such a way that they do not substantially impair the other characteristics of the body 1a and the bag 1 in general (e.g. external dimensions and / or interior dimensions). In the following, the transfer means 5 and the locking means 8, 10, 11 of the wheels 2a and 2b according to the invention will be described in more detail, starting with reference to Fig. 3. An elements generally belonging to them are shown in an exploded view. They include, firstly, a connecting piece 6 belonging to the transfer means 5 between the two wheels 2a and 2b. The connecting piece 6 is here an elongate tube or rod fitted (arrow P1) in a groove 1c arranged in the bottom 1b of the body 1a. The fall of the connecting piece 6 from the groove 1c is prevented - by the groove piece 1c '. In this way, the connecting piece 6 is adapted by a suitable clearance between the outer surface of the connecting piece 6 and the groove 1c and the inner surface of the groove piece 1c 'to pivot in its groove 1c about its longitudinal central axis A1 in connection with the base O 1b of the body 1a. This can also be done in other ways, for example by a fixed tube arranged in connection with the base, inside which the connecting piece is pivotally arranged. a S Swivel pieces 6a and 6b are arranged at both ends of the connecting piece 6, which
    The LO 0 is also adapted to pivot with the connecting piece 6 in the respective recesses 3a and 3b of the opposite sides of the body 1a of the bag 1. The pivot members 6a and 6b are further provided with mounting shafts 7a and 7b, which are thus located in the region of the lower part of the body 1a on opposite sides of the body 1a. The wheels 2a and 2b can be rotatably attached to these mounting shafts 7a and 7b at their central hubs (see also Fig. 6). The mounting shafts 7a and 7b are arranged with respect to the pivot axis A1 radially at the end of the distance and coaxially with respect to each other. Thus, the common pivot axis A2 formed by the mounting shafts 7a and 7b 5 is arranged to pivot about a parallel pivot axis A1, whereby the wheels 2a and 2b can also pivot with the mounting shafts 7a and 7b between the operating positions mentioned above in connection with Figs. The cover plate 1d covers and protects the wheels and pivots 6a and 6b in the recesses 3a and 3b.
    According to the invention, the bag 1 comprises locking means 8, 10 and 11 for locking at least two movable wheels 2a and 2b relative to the body 1a between at least two different operating positions of the pivot shaft A1, the operating positions of which are spaced D1 and D2 between the base and the lower edge of the bag. The locking means are arranged between (or in connection with) the first pivoting body 6a of the transfer means 5 and the body 1a and are thus located in connection with only one pivoting body 6a and thus one wheel 2a on one side of the lower part of the bag 1. Locking means according to a preferred embodiment of the invention will now be described in more detail with reference to Figures 4, 5 and 6. Figure 4 shows a side view of the first operating position of the wheels 2a and 2b locked. In it, the connecting piece 6 and its pivot axis A1 are pivoted with respect to the vertical direction of the body 1a to an angle of rotation 11 ° corresponding to the pivot angle of the first operating position of the mounting shafts 7a and 7b located on the pivots 6a and 6b with respect to the body. Rotation angle a1 is here = about 30 ° to 50 °. In it, the turning piece 6a having a sector-like plate shape rests »in its first position against the first counter surface 11a of the counter-shaping 11 formed in the recess 3a by means of a support surface 8c (see also Fig. 6) formed on the rear edge of the sector-like plate shape. The first counter surface 11a & thus prevents the pivoting body 6a from rotating about the pivot axis A1 counterclockwise 5 from its position shown in Fig. 4. Here, the counter-design 11 is a curved guide groove 11 corresponding to the curve of the trajectory of the integral pivot axis A2 formed around the wall 3 of the recess 3a, the end ends of which have mating surfaces 11a and 11b corresponding to different operating positions. Of these, 11a is thus the above-mentioned first mating surface and 11b is the second mating surface against which the support surface 8c of the turning piece 6a rests in the second operating position as described below. Figure 4 also shows a locking member 10 belonging to the locking means 8, 10, 11. Here, the locking member 10 comprises both the actual locking means for locking the pivot body 6a and thus the wheels 2a and 2b in its operating position and release means for releasing the pivot body 6a from locking the operating positions. In this embodiment, the locking member 10 includes a pivot lever 10a arranged to pivot for release about an axis 10h arranged in connection with the recess 3a.
    The locking means forming the lock include locking surfaces 10b and 10c formed in the first end slot 10g of the locking lever 10a. In Figures 4 and 5, a preferred shape of the slot 10g and the locking surfaces 10b and 10c is shown in broken lines at the first end of the pivot lever. Of these, the first locking surface 10b in the dryers 4 and 5 is an upwardly opening surface in the slot 10g, against which the anti-locking surface 8a belonging to the locking means rests. The anti-locking surface 8a, in turn, is arranged in shapes 8 arranged in connection with the first pivot piece 6a, which extend into the slot 10g. The main element 8 of the designs is a curved element formed as an extension of the outer circumference of the sector-like turning piece 6a. At the other edge of the element, in the vicinity of the fastening shaft 7a, said anti-locking surface 8a is formed which extends in connection with the first locking surface 10b inside the slot 10g. The above-mentioned structure is thus dimensioned so that the pivot body 6a and the wheels 2a and 2b further on the common shaft A2 lock in their first operating position on the one hand on the support surface 8c and the first mating surface on the other hand and on the second locking surface 10b and mating surface of the pivot lever 10a. 8a due to the co-operation. These above-mentioned surfaces also receive the forces applied to this structure in use.
    O I 30 - Figure 5 shows a side view of the second operating position of the wheels 2a and 2b locked. In it, the> connecting piece 6 and its pivot axis A1 are pivoted with respect to the vertical direction S of the body 1a to an angle of rotation 22 ° corresponding to the pivot angle of the second operating position of the mounting shafts 7a and 7b in the pivot members 6a and 6b about the pivot axis A1. The rotation angle α2 * is here about 100 ° to 150 °. The angle of rotation can be defined in many ways and is shown here in relation to the assumed vertical direction of the body and shown in the figures. In it, the turning piece 6a having the sector-like plate shape rests in its second position against the second counter-surface 11b of the counter-shape 11 formed in the recess 3a by means of a support surface 8c (see also Fig. 6) formed on the rear edge of the sector-like plate shape. The second counter surface 11b thus prevents the pivot body 6a from rotating clockwise about the pivot axis A1 from its position shown in Fig. 5. The second locking surface 10c of the locking lever 10a in Figs. 4 and 5 is a downwardly opening surface in the slot 10g, against which the second anti-locking surface 8b - (see also Figs. 4 and 6) belonging to the locking means rests. The second anti-lock surface 8b is also provided in the formations 8 arranged in connection with the first pivot body 6a. The second anti-lock surface 8b is located with respect to the anti-lock surface 8a on the opposite edge of the formulation 8, i.e. on the same edge as the support surface 8c on the pivot body 6a.
    The entire above-mentioned structure is thus dimensioned so that the pivot body 6a and the wheels 2a and 2b located further on the common shaft A2 lock in their second operating position on the one hand on the support surface 8c and the second mating surface 10c and on the other - due to the co-operation of the lock forming the surface 8b. These above-mentioned surfaces also receive the forces applied to this structure in use. According to a preferred embodiment of the invention, the locking member 10 comprises release means for releasing the pivot body 6a from locking the operating positions. The release means thus comprise a locking lever 10a, the other end of which forms a pressing part 10e. o A force F can be applied to the press part 10e, for example with the tip of the shoe (if desired> also by hand). This force F moves the pivot lever 10a about the above-mentioned shaft 10h O, pivoting the locking surfaces 10b and 10c aside from the locking between the respective counter-locking surfaces 8a 0 and 8b (depending on the operating positions) and releasing the pivot body 30a from the locking surfaces 10b and 10c. Thus, when moving from the first operating position according to Fig. 4 to the second operating position according to Fig. 3 5, the above-mentioned curved element i forming the main element 8 slides in the slot 10g until the second locking surface 8b pivots - towards the second locking surface 10c. In this case, the locking lever 10a pivots, preferably substantially opposite to the force F applied by the force element 10f, such as the spring, arranged in connection with the pressing part 10e to the pressing part 10e, whereby the second locking surface 10c and the second anti-locking surface 8b move against each other. At the same time, due to the dimensioning of the structure, the support surface 8c rests against the second abutment surface 11b. It should also be noted that the slot 10g supports the curved element as the curved element slides in the slot 10g, taking into account any lateral forces that may arise during the handling of the bag 1.
    - In the embodiment of the invention shown, the pivot axis A1 and the common pivot axis A2 are located relative to each other in the direction of travel R of the bag 1 at different levels in the first operating position and the second operating position of the wheels 2a, 2b. In this case, the common center of gravity of the wheels 2a and 2b and the connecting piece 6 and the pivoting pieces 6a and 6b remains in a different direction in the direction of travel of the bag 1, preferably in front of the pivot axis A1. This feature can be seen in particular in Figures 4 and 5. 2b of the lock according to Fig. 4, by pressing the pressing member 10e, the common pivot axis A2 with its wheels 2a and 2b pivots about the pivot axis A1 towards the second operating position (Fig. 5) when the bag 1 is lifted in its height direction (vertical in Fig. 4). When the wheels 2a and 2b are released from the lock according to Fig. 5 by pressing the press part 10e, the common pivot shaft A2 with its wheels 2a and 2b pivots about the pivot shaft A1 towards the first operating position (Fig. 4) under the action of the bag 1's own downward weight. Here, too, the tilt angle of the bag 1 itself may differ from that shown in Fig. 5.
    The present invention is not limited to the embodiment shown in the figures, but can be applied in many ways, for example with different variations in dimensions and functional structures and shapes within the scope defined by the claims.
