Description

The invention relates to a variable bicycle bag according to the preamble of claim 1.Variable bicycle bags are known which, in addition to the luggage carrier adapter system for attachment to a bicycle luggage carrier, also have a back support system which, after the bicycle bag has been removed from the bicycle luggage carrier, enables it to be supported on the back of the user. For this purpose, corresponding shoulder belts are provided on the bicycle pocket. Usually, the systems are provided on opposite surfaces of the bicycle bag, the luggage carrier adapter system on the bicycle side and the back carrier system on the belt side of the base body of the bicycle bag. Such variable bicycle bags can therefore also be used as a backpack.When used as a backpack, not only for aesthetic reasons do the rigid mechanical elements of the luggage carrier adapter system protrude from the bicycle bag. Particularly, when picking up or putting down the "backpack" and wearing the bicycle bag for a longer time in the hand, the user may hit these twisting members or feel uncomfortable when wearing.Furthermore, when used as a bicycle bag, the belts of the back carrier system are very disturbing. Unless additionally secured, they can hang loosely on the side facing away from the bicycle rack. Under certain circumstances, they can catch obstacles when passing near, or even enter the spokes of the bicycle, which can lead to sudden blocking of the wheel and thus in both cases represents a very high risk of falling over. The user often fails to provide additional securing, for example with a separate tensioning strap. Reasons for this are manifold, large level of ease or comfort or a tensioning strap is not currently available.In addition, the shoulder belts or the entire belt side of the bicycle bag can very easily become soiled, for example, by splash water or by cars driving past in the event of rain. Prior to use as a backpack, cleaning of the variable bicycle bag may be mandatory. The contamination of the shoulder belts could be avoided by making them removable. However, this would be very uncomfortable for the user, since a plurality of connections would have to be released when changing use to the bicycle bag. However, this does not exclude contamination of the belt side of the variable bicycle pocket. For the user, the comfortable simple and quick change of use with few handles is very important.As is known, the production of a bicycle pocket is a complicated process. Each additional element on the bicycle bag must be manufactured separately and each additional element requires an additional working step in the production of the variable backpack, which makes the production correspondingly more expensive.It is therefore the object of the invention to provide a variable bicycle bag which does not have the above-mentioned disadvantages, which is particularly comfortable to wear on the user, which does not represent a risk of an accident, in which contamination, in particular of the shoulder belts and of the belt side of the bicycle bag, is largely avoided, which enables a quick change of use as a backpack or as a bicycle bag and which requires few additional elements compared to a conventional variable bicycle bag and which is also cost-effective and simple to produce.This object is achieved by the features specified in claim 1.Advantageous further developments of the invention are specified in the dependent claims.The essential idea of the present invention is to provide a variable bicycle bag with a cover which can be folded easily and quickly via the luggage carrier adapter system to the bicycle luggage carrier or via the shoulder belts depending on the intended use.Thus, the variable bicycle bag is aesthetically pleasing when used as a backpack and the rigid mechanical elements of the carrier adapter system do not interfere with either picking up or removing or carrying the bicycle bag as a backpack variant.In addition, the shoulder belts behind the cover are well protected, so that they can no longer represent a risk of accident in the normal case. When the belt side is covered, good protection of the shoulder belts and of the entire belt side against soiling is also ensured.By simply releasing it at a connection point between cover and base body, the cover can be easily folded over in a first exemplary embodiment. Since only one cover and one connection point are required compared to a conventional bicycle bag that can be used as both a bicycle bag and a backpack, the production of the variable bicycle bag is very cost-effective.The invention is explained below with reference to an exemplary embodiment shown in the drawing.The following are shown: FIG. 1 a shows a perspective view of a variable bicycle pocket according to the invention with a covered bicycle side for use as a backpack according to a first exemplary embodiment FIG. 2 a shows a variable bicycle pocket according to FIG. 1 a in a perspective view with the belt side covered for use as a bicycle pocket FIG. 3 a is a schematic illustration of the folding over of the cover during a change of use in the variable bicycle pocket according to FIG. 1 a FIG. 1 b shows a further development of the variable bicycle pocket according to the invention in a perspective view with the bicycle side covered for use as a backpack FIG. 2 b shows a variable bicycle pocket according to FIG. 1 bin a perspective view with the belt side covered for use as a bicycle pocket FIG. 3 shows a schematic illustration of the folding over of the cover during a change of use in the variable bicycle pocket according to FIG. 1 b FIG. 4 shows a variable bicycle pocket according to a second exemplary embodiment of the invention FIG. 5 shows a variable bicycle bag according to a third embodiment of the invention FIG. 6 is a plan view of the belt side of a variable bicycle pocket according to the second and third exemplary embodiments of the invention with storage compartment FIG. 7 shows a variable bicycle bag according to the second and third exemplary embodiments of the invention with shoulder straps inserted into the storage compartment FIG. 8 is a top view of a luggage carrier adapter system FIGS. 9, 10 show schematic representations of the change of use according to an alternative movement variantFIG. 1 ashows a variable bicycle bag according to the invention in a perspective view with a covered bicycle side for use as a backpack. The variable bicycle bag has a base body 10 with an opening area 14 on its upper side, via which the variable bicycle bag can be filled.On a first surface of the base body 10 a back support system 12 is provided. It has two shoulder belts, of which only one of the training belts, the shoulder belt 12a, is visible. This first surface, which is referred to as the belt side of the bicycle pocket, is located on the opposite side of the base body 10 in this view and is therefore not visible. For carrying the bicycle bag with the hand, a carrying loop 13 is used above the back carrier system 12.The opposite second surface is covered by a cover 20. The cover 20 is fixed to the base body 10 by a coupling element designed as a buckle 22. For this purpose, a corresponding fastening means 1 in the form of a short strap piece 24 is used, at the end of which a corresponding counter piece 23 to the coupling element 22 is provided.Behind the cover 20 is the second surface of the base body 10 on which the rack adapter system 11 (FIG. 3 ) attachable to a bicycle rack is provided.The downwardly tapering cover 20 is detachably fixed to the underside of the base body 10 preferably at two points, which are arranged approximately on the center line of the underside, by means of two loops and a connecting element (e.g. eyelet). The loops with the connecting elements act like a hinge. When removed, the cover is a planar flat part and can be manufactured with a simple cut guide.The cover 20 together with the coupling element 22 is configured symmetrically to a perpendicular central plane ME.The bicycle bag consists essentially of TPU tarpaulins welded to one another. As a result, the bicycle bag can be used even in heavy rain, since it is watertight.FIG. 2 ashows the variable bicycle bag according to the invention in a perspective view with the belt side covered for use as a bicycle bag. In this mode of use, the two shoulder belts 12a, 12b are covered by the cover 20. The cover 20 is fixed to the same counterpart 23. For this purpose, it only needs to be folded over.FIG. 3 ashows the indicated movement of the cover 20 during the change between the two types of use, respectively backpack and bicycle bag. Since the cover 20 is connected to the base body 10 via the buckle 22 only at one connection point, only this connection point has to be released for changing and in order to be able to fold over the cover 20 adjoining it until it covers the opposite surface of the base body 10. In this end position, the cover 20 can be easily connected to the counterpart 23 via the buckle 22.The entire base body 10 with the fastening means 1 is, like the cover 20 with the coupling element 3, embodied symmetrically to a central plane ME.This embodiment of the variable bicycle bag is aesthetically pleasing when used as a backpack (FIG. 1a) because the carrier adapter system 11 is fully covered. The rigid mechanical elements of the carrier adapter system 11 do not interfere with the picking up, removal, or carrying of the variable bicycle bag, e.g., on the carrying loop 13.When used as a bicycle bag, the two shoulder straps 12 a, 12 bare protected behind the cover 20. This also ensures good protection against dirt and prevents jamming on obstacles. The change of use can be made very quickly by releasing the cover 20 at a single connection point. Since only the cover 20 with the buckle 22 as coupling element and a short strap piece 24 as well as the two connection points on the underside of the base body are required as additional production parts compared to a conventional variable bicycle pocket, and the entire bicycle pocket is completely symmetrical, the production of the variable bicycle pocket can be carried out very easily and thus also very cost-effectively. The cover 20 can also be manufactured very cost-effectively as a simple cut part.FIG. 1 bshows a further development of the first exemplary embodiment. Here, the cover 20 is formed to engage around the corner portions of the base body 20. It therefore expands downward. The cover 20 is also no longer planar and flat, but is curved at the lower two corner regions. This part requires a higher outlay from a manufacturing standpoint than a flat planar part. Correspondingly curved shapes must be produced, for example, for the welding process. In this further development, the shoulder belts 12a, 12b, in particular their thinner sections 12a' and 12b', are additionally protected against falling out, because the curved corner regions effectively serve as pockets for these sections.FIG. 2 bshows the further development of the bicycle bag according to the invention according to FIG. 1 b, with the belt side covered.FIG. 3 bshows the indicated movement of the cover 20 during the change between the two types of use of the backpack or bicycle bag according to the further development according to FIG. 1 a.FIG. 4 shows a second exemplary embodiment of the invention. This variable bicycle bag also has a base body 10, a back support system 12 with two shoulder belts, as well as a luggage carrier adapter system 11 for a bicycle luggage carrier and a cover 20. As in the first embodiment, the back support system 12 and the carrier adapter system 11 are disposed on opposite first and second surfaces, respectively. In contrast to the first exemplary embodiment, the upper part of the base body 10 can be rolled to close the opening region 14 and subsequently secured by a two-part strap with a snap connection 13 a. The cover 20 is designed as a flat flat part and can be folded over easily and quickly for a variant change by releasing the buckle 22 and then be connected again to the counterpart 23.FIG. 5 shows a third exemplary embodiment of the invention. Here, in the upper region of the base body 10 on its left and right side surfaces, a fastening means 1 in the form of a loop is provided in each case. Accordingly, corresponding coupling elements 3 in the form of hooks are provided on the upper corner portions of the cover 20, which coupling elements can be detachably connected to the associated loops 1. The cover 20 tapers downward and is detachably fixed on the underside of the base body 10. The loops with the connecting elements also act like a hinge. In the removed state, the cover 20 again represents a planar flat production part and can be produced with a simple cut guide. Here too, the base body 10 and the cover 20 are configured symmetrically to a central plane ME.In addition, a zipper 25 can be provided on the cover 20 outside the symmetry, which zipper closes an insert compartment for smaller objects, e.g. a handy phone.For changing the use, in this third embodiment, two connection points, i.e. the hooks 3, must be released. After the cover 20 has been folded over, it must be hooked in again. However, this folding over can also be referred to as very simple and quick.FIG. 6 shows a plan view of the belt side of the variable bicycle pocket according to the second or third exemplary embodiment. Here, the entire back support system 11 consists of a flexible plastic plate 18 to which the two shoulder belts 12 a, 12 band a support loop 13 aare fixed. The outer side of the plastic plate 18 is designed with several layers of padding. The plastic plate 18 is fastened to the base body 10 by means of a plurality of rivets 19, in the exemplary embodiment shown by seven. In addition, the back carrier system 12 also has a storage compartment 30, into which the lower portions of the shoulder belts 12a, 12b, in particular with the thinner portions 12a, 12b', can be inserted.FIG. 7 shows the shoulder belts 12 aand 12 binsertion into the storage compartment 30. In particular, the thin portions 12a' and 12b' from which the greater risk of accident occurs are safely stored in the storage compartment 30. With this storage compartment 30, it is no longer necessary for the cover 20 to engage around the corners of the base body 10, as shown in FIG. 1 b. It can be flat and planar, as shown in FIG. 1 a.FIG. 8 shows a top view of the second surface with the luggage carrier adapter system 11, which consists of two parts riveted to the base body 10.FIGS. 9 and 10 show how the use can be changed with an alternative movement variant. For this purpose, the cover 20 only has to be detached at one connection point. In this case, the cover is not folded over downwards, which would require the detachment of two connecting points, but rather is merely folded over laterally. To assist in this lateral folding, the cover may be slightly asymmetric. In addition, outside the symmetry, a further fastening point can be provided on the side surface of the base body with a loop 1. These two loops form a hinge-like connection with the corresponding hooks 3 on the cover 20. This embodiment variant constitutes a slight modification of the invention.The function of the invention is explained in detail below. All embodiments of the variable bicycle bag are aesthetically pleasing when used as a backpack (FIG. 1 ) because the carrier adapter system 11 is fully covered. The rigid mechanical elements of the carrier adapter system 11 do not interfere with the picking up as well as the picking up or carrying of the variable bicycle bag, e.g. on one of the carrying loops.When used as a bicycle bag, the cover 20 provides good protection against dirt. Also, the two shoulder belts 12a, 12b are stored safely behind the cover 20 in the normal case. This substantially prevents jamming on obstacles. A still secure stowage and thus an improved accident protection can be achieved either via the curved cover 20 (FIG. 1 b ) or by the additional stowage compartment 30 (FIG. 6 ).The change of use can be made very quickly by releasing the cover 20 either at a single connection point or at two connection points. Since only a few parts are required as additional production parts compared to a conventional variable bicycle pocket, and the entire bicycle pocket is configured symmetrically, the production of the variable bicycle pocket can be carried out very easily and thus also very cost-effectively.The cover 20 can also be manufactured very cost-effectively as a simple cut part. An additional storage compartment 20 may be required. The other possibility is to make the cover 20 curved, but this causes higher manufacturing costs.The essential elements of the variable bicycle bag according to the invention are a base body 10 with the back carrier system 12 and the luggage carrier adapter system 11 for attachment to and guidance from a bicycle as well as the cover 20. The cover 20 may optionally cover the back support system 12 or the carrier adapter system 11. The variable bicycle pocket has a symmetry with respect to the central plane ME of the base body 10. Furthermore, the 20 cover can be designed such that it covers the corner sections of the base body 10 and thus further reduces the risk of an accident due to the shoulder belts 12 a, 12 b. This is of particular importance in the case that the base body is not fully filled, and as a result the cover 20 is not tensioned over the base body 10 and therefore the shoulder belts 12 a, 12 bare not sufficiently fixed, because there is a clear intermediate space between the base body 10 and the cover 20. The cover 20 can be fixed in the upper region centrally or on the two sides. For additional securing of the shoulder belts 12 a, 12 b, a storage compartment 30 can alternatively be provided. The fastening means 1 can be designed very cost-effectively as loops and the coupling elements as hooks. In a simple manner, the back support system 12 is fixed to the base body 10 via a plastic plate. The watertightness of the variable bicycle pocket is ensured in that the base body 10 consists of welded TPU tarpaulins.
