Description

BIKE SUPPORT ATTACHMENT FOR A BAG OR THE LIKE TECHNICAL FIELD The invention relates to a bike support attachment for a bag or the like.

BACKGROUND The invention is advantageously used as a support attachment for a bike, such as a bicycle or a motorbike, for carrying a bag, backpack, briefcase or the like.

Backpacks that are provided to be comfortably worn on the back of a user and alsoadapted to be attached to the carrier of a bike are known in the art. There are also bagsand briefcases or the like known in the art that are provided to be attached to, and detached from, a carrier of a bike.

Various fastening means and arrangements are known for attaching bags to a bike anddetaching bags from the bike, such as a rack or a framework along the side of the bike.Usually, permanently mounted frameworks, racks or carriers of a bike adapted forattaching and detaching bags, are intended for a particularly designed bag. Often, theattachment means on the bike and the bag, respectively, have a specific design adaptedfor a particular bag with matching attachment means. This is undesirable. Further,permanently mounted frameworks, racks or carriers are often relatively heavy and bulky.As a result, the total weight of the bike may increase significantly. Yet further, when racksor carriers are not in use, they are unwanted. lt is possible to detach the rack or carrierwhen not in use but that is rarely an option because this may be time-consuming and/or undesirable if the rack or carrier is heavy and bulky.

Today, it is common that bikes are lacking a rack or a carrier at the back wheel. Further,an appropriate framework suitable as a support structure for carrying load may also be missing.

There is also a desire to improve the functionality and design of racks and carriers for abike. An improved functionality and design may improve the use and handling of a rack or carrier for a bike. Doing this may improve the overall variation of a support attachmentthat works for many different bikes with or without a rear carrier or rack and that can be adjustable to match a bag for easy mounting to the carrier or the rack.

There is also a desire to find an alternative instead of using the rack or carrier of a bike for carrying a bag, backpack, briefcase or the like.

US2019039671 A1 relates to a cycle carrier structure and is particularly, although notexclusively, concerned with such a structure for use in a system for carrying cargo upon abicycle. ln a specific embodiment it relates to a bicycle rack and pannier system which can be quickly attached and detached and yet is rigid enough to carry significant loads.

CN203567860 U relates to a foldable bicycle backseat. The foldable bicycle backseatovercomes the defect that at present, a lot of bicycles are not provided with backseats while people or articles need to be carried sometimes.

There is nevertheless a desire to further improve a support attachment for bicycle or amotor bike for carrying a bag, backpack, briefcase or the like, according to the objects mentioned below.

SUMMARY An object of the invention is to improve the support attachment for a bike for carrying abag, backpack, briefcase or the like. Another object of the invention is to provide a supportattachment for a bike that is adjustable to match a bag for easy mounting of it. A furtherobject is to provide a support attachment for a bag or the like that works for many differentbikes with or without a rear carrier. Yet a further object is to minimize the increase of thetotal weight of the bike with a support attachment for a bike for carrying a bag, backpack,briefcase or the like. Yet another object is to be able to quickly minimize the size andencumbrance of the support attachment for a bike for carrying a bag or the like without detaching the support structure when not in use.

The objects are achieved by a bike support attachment according to claim 1. Thus, theobjects are achieved by a bike support attachment for a bag or the like, comprising at least three rods. A first rod is configured to be pivotably attached by a first end of the firstrod. A second rod is configured to be pivotably attached by a first end of the second rod.The first end of the first rod and the first end of the second rod are configured to bepivotably attached at or close to a wheel hub of the bike. The first and the second rods areconnected by a third rod which is configured to be pivotably attached by a first end of thethird rod, when positioned adjacent a post or a wheel fork or the like in a frame structurefor a bike. The at least three rods are movably arranged relative each other. The at leastthree rods are arranged essentially parallel to each other in a folded resting position in afirst state (I) whereas the three rods may be spread out relative to each other in anunfolded active position in a second state (ll). A second end of the first rod and a secondend of the second rod are projecting essentially upwards in the longitudinal direction ofthe rods, configured for attachment of a bag or the like in the second state (ll) whereasthe support attachment is in the unfolded active position. The third rod is provided with alongitudinal aperture and the first rod and the second rod are displaceably arranged in thelongitudinal aperture such as an elongated slot. Moving the rods from the first state (I) tosecond state (ll), and vice versa, alter the position of the support attachment from, thefolded resting position to the unfolded active position and vice versa. Thereby, the parts ofthe support attachment can be gathered by folding it when not in use, to decrease its sizeand encumbrance. The support attachment can be mounted to a bike, with or without arear carrier, and may fit many different bikes. Thanks to the use of a few rods, alightweight and rigid support attachment can be provided. By adjusting the displacementof the rods relative each other in the unfolded active position it is possible to adjust thesupport attachment to match different bags. Furthermore, the first, second and third rodsare connected with a restricted displacement, limited by the length of the aperture, relativeeach other and are easily guided during movement to and from the first state (I) and thesecond state (ll). ln this way a rigid and lightvveight bike support attachment can be provided.

Yet further, the second upper ends of the first and second rods are suitable for attaching abag to the bike support attachment. For instance, it is sufficient if the bag has one or morerecesses or loops that can be hooked on the protruding, upwardly projecting, secondends. lt is also possible to provide specific attachments to the second upper ends and matching connecting means on the bag.

Yet further, it is possible to use an existing attachment on the bike as a pivot point for these rods. The hub may have a suitable attachment, but also other existing attachmentcan be used, such as at a chain protector attachment. lt is also possible to arrange for anew attachment to any of the posts of the bike frame or wheel fork which are connectingto the hub.

A further aspect of the invention is that the first rod and the second rod are at an angle toeach other, i.e. are diverging in the direction from the pivotably attached first ends of thefirst rod and the second rod to the second ends of the first rod and the second rod in thesecond state (ll) whereas the support attachment is in the unfo|ded active position. Byarranging the first ends of the first rod and the second rod close to each other, at or closeto a wheel hub of the bike, the rods can be diverging in the direction to the second ends ofthe rods when the support attachment is in the unfo|ded active position. Then, it is alsopossible to arrange the rods close to each other and essentially parallel to each other when brought into in the folded resting position in a first state (I). ln yet a further aspect of the invention, a fourth rod is attached to the third rod, the fourthrod is configured to lock the third rod in the unfo|ded active position in the second state(ll). By moving the fourth rod, it can be used to keep the third rod in an essentiallyhorizontal position and lock the bike support attachment into the second state (ll).Suitably, the fourth rod is a folding rod comprising at least two folding sections, configuredto snap together to form an extending rod. When the bike support attachment should bealtered to the folded resting position in a first state (I), the folding rod easily folds intopieces, by pull apart the folding sections. Thereby, easily manoeuvrable locking and unlocking of the bike support attachment is provided.

Preferably, the upper portions of the first and second rods are protruding out from thelongitudinal aperture in the first state (I) and the second state (ll). Thereby, the bikesupport attachment can be easily manoeuvrable by pulling out the upper portions from thefirst and second rods resting position in the first state. This will force the third rod to rotate to an essentially horizontal position in the unfo|ded active position in the second state (ll).

Further advantages and advantageous features of the invention are disclosed in the following description and in the dependent claims.BRIEF DESCRIPTION OF THE DRAWINGS Below, embodiments of the invention will be described with reference to the drawings, inwhich: - fig. 1A shows a schematic view of a bike support attachment for a bag or the likeaccording to an embodiment of the invention, in an unfolded active position in asecond state, - fig. 1B shows a schematic view of the bike support attachment in fig. 1A, in afolded resting position in a first state, - fig. 1C shows a schematic enlarged view of the upper portion of the bike supportattachment in fig. 1A, in the unfolded active position in the second state, - fig. 1D shows a schematic enlarged view of the upper portion of the bike supportattachment in fig. 1B, in the folded resting position in a first state, - fig. 1E shows a schematic enlarged view at a portion A of the bike supportattachment in fig. 1A, in the unfolded active position in the second state, - fig. 1F shows a schematic enlarged view at a portion B of the bike supportattachment in fig. 1B, in the folded resting position in the first state, - fig. 2A shows a schematic view of a bike support attachment for a bag or the likeaccording to another embodiment of the invention, in an unfolded active position ina second state, and - fig. 2B shows a schematic view of the bike support attachment in fig. 2A, in a folded resting position in a first state.

DETAILED DESCRIPTION OF El\/lBODll\/IENTS OF THE INVENTION Fig. 1A-F shows a bike support attachment 1 for a bike, such as a bicycle or a motorbike,for carrying a bag, backpack, briefcase or the like, according to an embodiment of theinvention. The support attachment 1 comprises at least three longitudinal extending rods,a first rod 2, a second rod 4 and a third rod 6. For the purpose of using the bike supportattachment 1 for carrying a bag, backpack, briefcase or the like, the pivotal attachment ofthe respective first ends 2a, 4a of the first rod 2 and the second rod 4 may be located at alower part of a bike. The first ends 2a, 4a are in the following called first outer ends, whichmeans at or close in the vicinity of the ends of the rods 2a, 4a of the first rod 2 and thesecond rod 4. The bike support attachment may also be called bike rear rack if located at the back of a bike. The first rod 2 and the second rod 4 are configured to be pivotablyattached by their respective first outer end 2a, 4a, at an attachment of a wheel shaft or atframe or fork portion close to a wheel hub of the bike. lt is possible to use an existingattachment point on a bike frame as a pivot. However, other existing attachments can beused, such as at a chain protector attachment. lt is also possible to arrange for a newattachment to any of the posts connecting to the hub region of the bike. Suitably, the firstouter end of first rod 2 and the first outer end of the second rod 4 are configured to bepivot around the same pivot point. More preferably, as i||ustrated in Figs. 1E and 1F, thefirst rod 2 and the second rod 4 are pivotably attached to a common pivotal shaft arrangedin a housing 8 of the support attachment 1, whereas the housing 8 can be attached to the bike, for example to a fork or mudguard support.

The first and the second rods 2, 4 are connected by the third rod 6. The third rod 6 isconfigured to be pivotably attached at a first outer end 6a to a pivoting frame attachment11. The attachment of the first outer end 6a of the third rod 6 to pivoting frame attachment11 is arranged at a distance from first outer ends 2a, 4a of the first rod 2 and the secondrod 4. When mounting the support attachment 1 to a bike, the pivoting frame attachment11 for the first outer end 6a of the third rod 6 may suitably be located at an upper part ofthe bike, such as close to, or about the same height as a seat of the bike or at a heightbelow the seat, for example the upper end of the seat attachment tube. The pivotingframe attachment 11 can be mounted to a bike, with or without a rear carrier by anysuitable means, for example, by a clamp or by using existing mounting means. The support attachment 1 may fit many different bikes.

The at least three rods 2, 4, 6 are movably arranged relative each other. The at leastthree rods 2, 4, 6 are arranged essentially parallel to each other in a folded restingposition in a first state (l) as seen in Fig. 1B. The three rods 2, 4, 6 are displaceablyspread out relative each outer in an unfolded active position in a second state (ll), as seenin Fig. 1A. Moving the rods 2, 4, 6 from the first state (I) to second state (ll), and viceversa, alter the position of the support attachment 1 to the folded resting position (l) or theunfolded active position (ll). Thereby, the parts of the support attachment 1 can begathered by folding it when not in use, to a decreased size and encumbrance as evidentfrom Fig. 1B. The use of only a few rods may provide a light\Neight and rigid supportattachment 1. By displacement of the rods 2, 4, 6 relative each other in the unfolded active position (I) it is possible to adjust the support attachment to match different bags.The second ends 2b, 4b are in the following called second outer ends, which means at orclose in the vicinity of the ends of the rods 2b, 4b of the first rod 2 and the second rod 4.Preferably, a second outer end 2b of the first rod 2 and a second outer end 4b of thesecond rod 4 may project essentially upwards in the longitudinal direction of the rods andbe, configured for attachment of a bag or the like in the second state (ll) whereas thesupport attachment is in the unfolded active position. Thereby, the second upper ends 2b,4b of the first and second rods 2, 4 are suitable for attaching a bag to the bike supportattachment. For instance, it is sufficient if the bag has one or more recesses or loops thatcan be hooked on the protruding second upper ends 2b, 4b. Preferably, the second upperends 2b, 4b of the first and second rods 2, 4 can be provided with a curved profile towardsthe ends 2b, 4b. Thereby, the bag or the like having loops or recesses, for instance at abackside, can be hooked on by tilting the bag such that the ends 2b, 4b, enters into thecorresponding loop or recess, respectively, at the bag. Once the ends 2b, 4b, haveentered completely into the corresponding loop or recess, respectively, the bag can bereleased to hang freely by itself in engagement on the ends 2b, 4b. Thanks to the curvedprofile at the ends 2b, 4b, the bag can be properly secured from being released by itselffrom the support attachment 1. lt is also possible to provide specific attachments to thesecond upper ends 2b, 4b and matching connecting means on the bag. At a position onthe first rod 2 and/or the second rod 4, between the first ends 2a, 4a and the second ends2b, 4b, attachment means 9 may be provided, such as a knob or magnet, suitable for attaching a lower portion of the bag to the bike support attachmentSuitably, the first rod 2 and the second rod 4 are diverging in the direction from thepivotably attached first outer ends 2a, 4a of the first rod 2 and the second rod 4, to thesecond outer ends 2b, 4b of the first rod 2 and the second rod 4 in the second state (ll),whereas the support attachment 1 is in the unfolded active position. By arranging the firstouter ends 2a, 4b of the first rod 2 and the second rod 4 close to each other, for instanceat or close to a wheel hub of the bike, the rods 2, 4 can be diverging in the direction to thesecond ends 2b, 4b of the rods 2, 4 when the support attachment 1 is in the unfoldedactive position. Then, it is also possible to arrange the rods 2, 4, 6 close to each other andessentially parallel to each other when brought into in the folded resting position in a firststate (I). ln yet a further aspect of the invention, a fourth rod 10 is attached to the third rod 6, the fourth rod 10 is configured to lock the third rod 6 in the unfolded active position in thesecond state (ll). By operating the fourth rod 10, it can be used to keep the third rod 6 inan essentially horizontal position and lock the bike support attachment 1 in the unfoldedactive position in the second state (ll). Suitably, the fourth rod 10 is a folding rodcomprising at least two folding sections 10a, 10b, configured to snap together to form anextending rod 10. An elastic cord 12 may be attached on the inside, that may run throughthe folding sections 10a, 10b of the extended rod 10. When the bike support attachment 1should be a|tered to the folded resting position in a first state (I) and the length of thefourth rod reduced, the folding rod 10 can be easily folded into pieces, by pull apart thefolding sections 10a, 10b. Thereby, an easily manoeuvrable locking and unlocking of thebike support attachment 1 is provided. A push button 14 may be provided on the outsideof folding rod 10, in connection with a locking mechanism on the inside, for unlocking ofthe folding sections by pressing the push button 14. An alternative to a push button 14 is alocking sleeve that is slidably arranged on the outside of the folding rod 10 between twofolding sections 10a, 10b and spring biased in the locked position between two foldingsections 10a, 10b. Unlocking of the folding sections 10a, 10b is done by displacing thelocking sleeve from one of the folding sections 10a, 10b. Thereby, the folding rod 10easily folds into pieces. Alternatively, according to an embodiment, the fourth rod 10 can be a telescopic rod.

As shown in Figs. 1A-D, the third rod 6 may be of asymmetric shape. The third rod 6 maycomprise of two longitudinally extending walls, a first wall 6c and a second wall 6d, thatmay be arranged perpendicular to each other to form an L-shaped profile. The first wall 6cmay be configured for being pivotally arranged for attachment against a vertical surface ofa bike. According to an embodiment of the invention, the second wall 6d of the third rodmay be provided with a longitudinal aperture 16. The second ends or regions close to thesecond ends of the first rod and the second rod are configured to be displaceablyarranged in the longitudinal aperture 16. Thereby, the first, second and third rods 2, 4, 6are connected with a restricted displacement relative each other and are easily guidedduring movement to and from the first state (I) and the second state (ll). The second wall6d may be provided with a curved portion 18 in an outer section 20 towards the first end6a of the third rod 6. The second wall 6d may extend straight along an upper edge 6e ofthe first wall 6c from a second end 6b of the third rod 6 to the curved portion 18, where thewall is curved towards a lower edge 6f of the first wall 6c. At the end of the curved portion18, the longitudinal aperture 16 ends at an inner short side 16a. At an opposite side of the third rod 6, the longitudinal aperture 16 ends at an outer short side 16b. Preferably, anupper portion at the second ends 2b, 4b of of the first and second rods 2, 4 can protrudeout from the longitudinal aperture 16 in the first state (l) and the second state (ll), at theend of the curved portion 18 in the outer section 20 towards the first end 6a of the thirdrod 6. Thereby, the bike support attachment 1 can be easily manoeuvrable by pullingapart the upper portions at the second ends 2b, 4b from the first and second rods 2, 4resting position in the first state. This will force the third rod 6 to rotate to the essentially horizontal position in the unfolded active position in the second state (ll). ln operation, the support attachment is moved from the folded resting position in a firststate (l) as shown in Fig. 1B, by pulling the upper portion of the second rod towards itsintended position in the second state (ll). The first and the second rods are preferablypivotally attached at the first ends in a common pivotal shaft 7 arranged in a housing 8 asdescribed above and shown in Figs. 1E-F. The second rod 4 may be provided with aprotrusion 4p, such as a heel, that pushes on the first rod 2 to force it to follow themovement of the second rod when the second rod 4 is pulled out. The third rod 6 ispushed upwards from the folded resting position in the first state (I) by the second rod 4pressing on the outer short side 16b of the aperture 16 in the third rod 6 when the secondrod 4 is pulled out from the resting position. The second end 6b of third rod 6 travels froma position on the second rod 4 in-between the first end 4a and second end 4b of thesecond rod 4, upwards to a position close to the upper portion at the second end 4b of thesecond rod 4. Simultaneously the third rod 6 travels over the first rod 2 that is freelyarranged in the longitudinal aperture 16. When the third rod 6 has reach the position closeto the upper portion at the second end 4b of the second rod 4, the second rod 4 can bereleasably attached in position at the outer short side 16b of the aperture 16 in the thirdrod 6 for example by a magnet device or a rubber element or the like. The freely arrangedfirst rod 2 can then be releasably attached in position at the inner short side 16a of the aperture 16 in the third rod 6 by for instance a magnet device or a rubber element.

Thereby, as shown in Fig. 1A and 1C, the first, second and third rods 2, 4, 6 have reachedthe unfolded active position in the second state (ll), and are displaceably spread outrelative to each other. The forth rod, folding rod 10, has followed the movement from thefolded resting position in the first state (l), where the folding rod 10 is pull apart in thefolding sections 10a, 10b to the the unfolded active position in the second state (ll), wherethe folding rod folding sections 10a, 10b, is configured to snap out to an extending rodThe extended folding rod 10 keeps the third rod 6 in an essentially horizontal position H and locks the bike support attachment 1 in the unfolded active position in the second state (u).

Further, in operation for moving the bike support attachment to the first state (I) from theunfolded active position in the second state (ll), as shown in Fig. 1A, the extended foldingrod 10 is unlocked. The first and second rods 2, 4 are released from their attachedpositions at the third rod 6. The upper portion at the second end 4b of the second rod 4 ispulled in direction towards the first rod 2. The second end 6b of third rod 6 movesdownwards from a position close to the upper portion at the second end 4b of the secondrod 4 back to a position on the second rod 4 in between the first and second ends 4a, 4bof the second rod 4. Simultaneously the third rod 6 travels downwards over the first rod 2until the first, second and third rods 2, 4, 6 have reached the folded resting position in a first state (I) as shown in Fig. 1B and 1D.

The length of the first rod 2 and length of the second rod 4 may be the same or may beroughly the same.
