Description

FOLDING CARRY FRAME FOR REAR SIDE INSTALLATION ON BICYCLES TECHNICAL FIELD OF THE INVENTION

The invention relates to the transport of luggage by bicycle, and more particularly to a luggage transport structure intended to be mounted on the side of the rear wheel of the bicycle.

TECHNOLOGICAL BACKGROUND

The bicycle is an economical mode of transport suitable for both everyday journeys and more distant excursions that can extend for weeks or more. In both situations, the cyclist is naturally confronted with the need to transport luggage of varying volumes and contents. To this end, numerous solutions have been developed to allow luggage to be carried directly on the bicycle.

Among the existing solutions, those which allow the largest volumes to be stored while limiting lateral bulk and maintaining the stability of the bicycle consist of using storage spaces attached to the rear of the bicycle, on one side of the wheel back. Patent applications US 3,786,972, FR2467763A1 and FR2250333A5 describe removable saddlebags that can be attached and detached from the rear rack of a bicycle. Other systems offer storage which, although removable, is intended to be used permanently attached to the bicycle, such as the saddlebags described in document FR2480220A1. We can also cite solutions consisting of bags intended both for carrying on a user's back and directly attached to their bicycle, as described in documents US 5,765,733 and US 2012/0255983 A1. However, in all the cases mentioned above, the panniers must be provided with structures intended for attachment to the bicycle, adding to their weight and imposing an appearance and characteristics not necessarily desired by the user. Thus, the user's choice is reduced as to the type of luggage or bag he wishes to use when he is not traveling by bicycle, or requires him to carry an additional bag in addition to the bicycle panniers.

In addition, when the bags are intended to remain permanently on the bicycle or the user considers it impractical to detach and reattach them each time they are used, the user must carry out transfer operations, for example from a shopping bag. shopping with the bag.

Finally, the volume and characteristics of a bag are fixed, while, depending on their activities, the user may wish to use several types of bags, for example a shopping bag for going to the market, a sports bag for going to participate in sports activities, or a travel bag for going on a bike ride. The user may also wish to carry an item beyond the capacity of their bicycle bag, such as a large package.

Even if there are foldable bicycle bags as described for example in document US2014138417A1, we cannot increase the volume of bicycle bags at will to anticipate all possible uses, essentially for reasons of bulk and safety, considering that a cyclist remains a fragile road user compared to motorists, and that to move fluidly in road traffic, the width occupied by the bicycle and its equipment on the road must be reduced as much as possible.

The applicant's objective is to provide cyclists with a universal luggage carrying solution, applicable to all types of luggage, of practical use for a wide range of volumes to be transported by bicycle, without significantly impacting the bulk of the bicycle.

Thus, the object of the invention is a folding carrying structure intended to be attached laterally to a rear bicycle luggage rack. With a view to achieving this object, the invention relates to a folding carrying structure forming a rack carrying, intended to be laterally integral with a rear luggage rack of a bicycle, the structure comprising a support element, with a periphery essentially defined by two lateral elements and a transverse element linking the two lateral elements; a support element in pivotal connection with the support element along a pivot axis substantially parallel to the transverse element of the support element, capable of taking a closed configuration, in which the support element is stored against the support element, and an open configuration, in which the support element is capable of supporting luggage; a pivoting blocking element of the support element; and a stopping element projecting from a first of the two lateral elements of the support element at least in the open configuration, so as to, in function, prevent the luggage from sliding towards the front of the bicycle, the stopping element defining with the support element and the support element a loading volume of the carrying structure.

Such a carrying structure makes it possible to freely transport a wide variety of luggage on a bicycle, including a bag or shopping bag chosen by the user and not having fixing elements dedicated to hanging on a bicycle. Thus, the user does not have to transfer objects to be carried from a bag to a bicycle bag, but can directly attach his bag to the bicycle by means of the carrying structure. This structure constitutes an alternative to conventional bicycle bags in the same way that a carrying rack constitutes an alternative to backpacks: the objects to be transported are supported and held by the structure without being inserted into a container.

In addition, this structure being foldable, it has no impact on the extension of the bicycle when not in use and is in a closed configuration.

According to additional non-limiting characteristics of the first aspect of the invention, considered individually or according to any technically feasible combination:

- the support element may substantially define a first extension plane, the structure may further comprise a first protective plate fixed to the support element and extending substantially parallel to the first extension plane;

- the support element may substantially define a second extension plane, the structure may further comprise a second protective plate fixed to the support element and extending substantially parallel to the second extension plane;

- the support element can be an element for fixing the structure to the bicycle, the structure can be configured to be hung laterally on the rear luggage rack of a bicycle, in which the support element can be provided at least one first device for attaching to the bicycle luggage rack;

- the at least one first device for attaching to the bicycle luggage rack may be an upper hook configured to be fixed to a side element of the luggage rack and comprising a first generally L-shaped part which is made up of a first bar and a second bar, a second part and a third part, in which the first bar and the second part are designed so as to grip the transverse element of the support element, in which the first bar and the third part are designed so as to grip the side element of the luggage rack, and in which the third part is designed to be fixed to the second bar by means of a fixing part housed in a recess of the third part;

- the first protective plate may comprise at least one recess so as to leave the recess of the at least one first attachment device accessible to a user when the structure is mounted on a bicycle;

- the structure may comprise a bicycle rear luggage rack on which the support element is intended to be mounted rigidly, this rear luggage rack being configured to be fixed to a seat tube of a bicycle by means a clamping device;

- the stopping element can be a generally U-shaped element having two ends fixed to the first of the two lateral elements of the fixing element; And

- the support element can extend laterally over a first distance in the open position, in which the pivot blocking element of the support element projects substantially perpendicular to the support element from the two lateral elements of the support element, capable of extending laterally over a second distance less than the first distance, the support element and the blocking element being designed in such a way that the blocking element blocks a pivoting of the support element and thus defines the open configuration.

The invention extends to a kit designed to form the folding carrying structure according to the invention, comprising the support element; the support element; and the stopping element.

DETAILED DESCRIPTION OF THE INVENTION

Figures 1 to 8 illustrate several variants of implementation of a first embodiment of the invention, which relates to a folding carrying structure 100, designed to be mounted on a bicycle 1, and more specifically attached to a lateral element 12 of the rear luggage rack 10 which is fixed to the rear of the saddle 8 of the bicycle, above the rear wheel 6 of this bicycle. Thus, the carrying structure 100 is designed to be attached laterally to the bicycle, to the rear luggage rack.

In all variants, the structure 100 comprises three main elements: an element 110 for fixing the structure to the bicycle, a support element 120 in pivotal connection with the fixing element 110 and designed to support luggage on the side of the rear wheel of the bicycle, and a stopping element 130 designed to prevent the luggage from sliding towards the front of the bicycle, for example when braking, and to prevent luggage from falling or getting in the way the cyclist's pedaling.

The element 110 for fixing the structure to the bicycle also has a function of supporting luggage placed on the support element 120, and, in the present document, reference may also be made to this element 110 as the support element 110.

As illustrated by Figures 1 to 4, the element 110 for fixing the structure to the bicycle comprises a first crossbar 110T and two first side bars 110L ₁ and 110L ₂ each extending from a respective end of the crossbar 110T , thus defining a general “U” shape, inverted when the structure is mounted on the bicycle. The bars 110T, 110L ₁ and 110L ₂ form a periphery of the element 110 and define an extension plane of the element 110.

The member 110 is equipped with a pair of upper mounting hooks 114A and 114B attached to the first crossbar 110T and designed to each be attached to the side member 12 of the rear rack of the bicycle. The hooks constitute a primary attachment device to the luggage rack. A particular implementation of hooks is detailed below, in relation to the .

The element 110 also comprises a slide 112 connecting the side bars 110L ₁ and 110L ₂ to each other, at an intermediate level between high and low ends thereof. The “high” and “low” qualifications are to be taken in an explanatory context, where the structure 100 is considered mounted on a bicycle in use. The slide is equipped with a lower fixing hook 113, designed so as to be able to slide along the slide and be blocked thereon at a level chosen by the user to pass behind (from the point of view of the user) a fixing rod 14 of the luggage rack. The function of this third fixing hook is to prevent the carrying structure from tilting around the lateral element 12 of the luggage rack in the event of travel on an irregular road, with, for example, potholes . The slide, joining the two side bars 110L1 and 110L2, has the two advantages of stiffening the structure and allowing a large range of adjustment, allowing the adaptation of the carrying structure to a wide variety of types of bicycles.

The support element 120 constitutes a folding platform which comprises a peripheral frame defining a plane of extension of the support element 120 and formed by a second transverse bar 120T and two second side bars 120L ₁ and 120L ₂ each extending from a respective end of the second crossbar, thus forming a general “U” shape.

Two free ends of the two second side bars 120L ₁ and 120L ₂ located opposite the second transverse bar 120T are each fixed in the lower part of one respective of the two first side bars 110L ₁ and 110L ₂ of the element 110 pivotally around an axis Ax substantially parallel to the first transverse bar 110T of the element 110. When the structure 100 is mounted on a bicycle, the axis Ax is preferably substantially horizontal, substantially parallel to a straight line indicating a front/rear orientation of the bicycle, which may correspond to a straight line passing through the centers of the front and rear wheels. Any type of pivot connection known in the field of mechanics can be used. The pivot connection used may be provided with a torsion spring (not illustrated) arranged to tend to bring the support element 120 back towards the fixing element 110 so as to keep it raised when not in use. The support element 120 can thus move from a so-called “open” configuration, in which the support element 120 is in a position such that it is able to accommodate luggage that the user would place on it as illustrated in (A). of the , to a so-called “closed” configuration, in which the support element 120 is folded against the element 110 as illustrated in (B) of the .

The support element 120 may include another transverse bar 120T ₂ between the two second side bars 120L ₁ and 120L ₂ , substantially parallel to the second transverse bar 120T. The other transverse bar 120T ₂ fulfills the functions of stiffening the structure and supporting luggage placed on the support element.

In a first variant, illustrated by the , the stopping element 130 consists of a stopping compass fixed between the support element 120 and the side bar 110L ₂ . This stopping compass also has the function of blocking the support element 120 in its rotation, thus defining the position of the support element 120 in the open configuration of the structure 100, in which the angle formed by the plane of extension of the fixing element and the extension plane of the support element being substantially between 80° and 90°. An angle of less than 90° is advantageous in that it facilitates positioning of the luggage on the support element, limiting the tendency that the luggage could have to slide outwards.

In a second variant, illustrated by the , the stopping element 130 has a general "U" shape, with two ends fixed to the side bar 110L ₂ of the fixing element 110. More specifically, the stopping element 130 here comprises a third transverse bar 130T and two third side bars 130L ₁ and 130L ₂ each extending from a respective end of the third cross bar 130T, thus forming the U shape, two free ends of the two third side bars 130L ₁ and 130L ₂ opposite the third cross bar 130T being fixed to the side bar 110L ₂ of the fixing element 110, as illustrated for example in (B) of the .

The second variant comprises a strap 140 fixed between the support element 120 and the side bar 110L ₂ . This strap has the function of blocking the support element 120 in its rotation, thus defining the position of the support element 120 in the open configuration of the structure 100, in which the angle formed by the extension plane of the fixing element and the extension plane of the support element being substantially between 80° and 90°.

In the same way that the stopping compass of the first variant fulfills the two functions of stopping the luggage and blocking the rotation of the support element, it can be envisaged that the strap 140 fulfills these two functions and is therefore considered as a stopping element, in which case, having a stopping element 130 dedicated solely to luggage is not a necessity. Conversely, we can consider that a stopping element 130 as illustrated by can be optimally dimensioned for the sole function of stopping the luggage, in which case it may be advantageous to also integrate it into the structure of the first variant in addition to the compass, the main function of which would then be to block the rotation of the support element.

In the first or second variant, once the compass is opened or the strap is stretched, the support element 120 may abut against the bottom of the part 110, which thus contributes to blocking the support element.

In a third variant, illustrated by Figures 3 and 4, the support element 120 extends laterally over a first distance d1 in the open position. A pivoting blocking element 152 of the support element 120 projects substantially perpendicular to the fixing element 110 from the two lateral elements 110L ₁ and 110L ₂ of the fixing element 110, and extends laterally over a second distance d2 less than the first distance d1. Unlike the support element 120 which can pivot around the axis Ax, the blocking element 152 has a fixed position. The support element 120 and the blocking element 152 are designed such that the blocking element 152 blocks a pivoting movement of the support element 120 and thus defines the position of the support element 120 in the open configuration.

More specifically, the blocking element 152 comprises a peripheral frame defining a plane of extension of the element 152, and formed by a fourth transverse bar 152T and two fourth side bars 152L ₁ and 152L ₂ each extending from a respective end of the fourth crossbar 152T, thus defining a general “U” shape. The support element 120 and the blocking element 152 are designed in such a way that, when the support element 120 pivots around the axis Ax, the other transverse bar 120T ₂ of the support element 120 comes into abutment against the fourth crossbar 152T of the blocking element.

In use, the extension plane of element 152 is substantially horizontal (orientation considered when the structure is mounted on a bicycle in use). In addition to its function of blocking the pivoting of the support element 120, the element 152 illustrated in Figures 3 and 4 can also serve as a support for luggage, provided that it has a suitable shape and volume, c that is to say that it can be retained by the transverse bar 152T when it is placed against the fixing element 110. Thus, with this third variant, the folding carrying structure 100 can be used without having to pass in open configuration, which avoids handling when the size of the luggage to be transported does not require the use of the support element 120.

One or more shock absorbers 154, for example made of rubber, can be mounted on one or other of the transverse bars 120T2 and 152T, so as to absorb shocks between these two bars and limit the associated noise, which improves comfort. of the cyclist when the carrying structure is in open configuration. Made of a sufficiently flexible material, this or these shock absorbers can also be used to attenuate shocks to the objects being transported.

With regard to the closed configuration, the fixing element 110 may be provided with a device 117 for holding the support element 120 in the folded configuration, for example by clipping using a clip, as illustrated in (B) of the . Such a clip can be attached to one of the bars of the fixing element and configured to accommodate and hold a corresponding bar of the support element 120, whatever the variant considered.

In all cases, the structure 100 constituted by the elements 110, 120 and 130 can be considered as a carrying rack suitable for transporting luggage or objects by bicycle.

It can also be said that the stopping element 130 or 140 defines with the support element 110 and the support element 120 a loading volume of the carrying structure, without however the baggage or objects to be transported being limited to such a volume. The loading volume as defined above is intended to clarify the area in which luggage can be placed for optimal conditions of stability and mooring, and therefore safety, during its transport.

The bars of the elements 110, 120, 130 in the cases of Figures 1 to 4, 7, 8 and 152 in the case of the and 4 can be made of steel or aluminum metal tubes, secured to each other by welding or any other fixing method, or be formed by bending the same tube.

There illustrates a particular implementation of the fixing hooks 114A and 114B, from two different viewing angles in (A) and (B). The hooks are each configured to be fixed to a side bar 12 of the luggage rack 10, each upper hook comprising a first part 114 ₁ with a general "L" shaped profile consisting of two bars L1 ₁ and L2 ₁ , a second part 114 ₂ and a third part 114 ₃ with a general “L” shaped profile made up of two bars L1 ₃ and L2 ₃ .

The first bar L1 ₁ of the first part 114 ₁ and the second part 114 ₂ are designed so as to grip the transverse bar 110T of the fixing element 110; they can for example each comprise a first semi-cylindrical recess designed to receive the crossbar. Tightening between the first bar and the second part can be obtained by screwing, in the second part 114 ₂ , a first screw (not shown) which is housed in a first recess Tr1 formed in the first bar L1 ₁ .

The first bar L1 ₁ of the first part 114 ₁ and the first bar L1 ₃ of the third part 114 ₃ are designed so as to grip the lateral element 12 of the rear luggage rack 10 of the bicycle, they can for example each comprise a recess provided to receive the lateral element 12. The assembly of the first part 114 ₁ with the third part 114 ₃ can be carried out by screwing, into the second bar L2 ₁ of the first part 114 ₁ , a second screw (not shown) being housed in a second recess Tr2 formed in the second bar L2 ₃ of the third part 114 ₃ . The screws mentioned above act as fasteners.

The L shapes are advantageous in that they help to position the structure on the luggage rack, the L forming a convenient stop for properly positioning the hooks by traction after passing one leg of the L pointing downwards behind the side element 12 of the luggage rack. In addition, the fixing by means of a second screw and the positioning of the latter, accessible but not very visible, can have a deterrent effect regarding the theft of the carrying structure.

The folding carrying structure 100 may also include, whatever the variant considered, protective plates intended to protect luggage placed on the support element 120 from the projection of water or mud in advance of the rear wheel. Indeed, a conventional bag fulfills this role since it houses the items to be transported directly inside a volume defined, for example, by a waterproof fabric pocket. In the case of the present invention, the luggage to be transported remains outside any protective pocket, simply placed on the support element 120, and it is therefore preferable to limit the risk of dirt or wetting.

To this end, a first protective plate 116 can be fixed to the fixing element 110. The fixing element 110 substantially defines a first extension plane, the first protection plate extends substantially parallel to this first extension plane, as illustrated by the .

If necessary, this first protective plate 116 must leave the second recesses Tr2 of the upper fixing hooks 114A and 114B accessible. This effect can be achieved by varying the dimensions of the plate 116, as illustrated by the . Alternatively, the first plate may include recesses 116R, as illustrated in Figures 5 and 6. This latter geometry allows better protection of the luggage, the surface of the protection plate being maximized.

When the structure 100 includes the slide 112 and the lower fixing hook 113, the first plate can also include an elongated opening 116Open, which has the advantage of leaving the slide and the second hooking device accessible to a user when the structure is mounted on a bicycle and the fixing element 110 interposed between the protection plate 116 and the bicycle 1, as illustrated by the . Thus, hooking and adjusting the position of the fixing hook 113 are made easier. Alternatively, when the plate 116 is interposed between the element 110 and a fixing rod 14 of the luggage rack, the elongated opening 116Ouv can be provided to allow the lower fixing hook 113 to slide, as illustrated by the

Also, a second protective plate 126 can be fixed to the support element 120. The support element 120 substantially defines a second extension plane, the second protection plate extends substantially parallel to this second extension plane, as illustrated by the , there and the .

The first protection plate 116 and the second protection plate 126 can be made of plates of wood or plastic, canvas, mesh or metal, and be fixed respectively to the element 110 and to the element 120 by means screws, clamps or any other fixing element suitable for this use.

There also illustrates that the structure 100 can comprise a strap 160 attached to the two side bars 110L ₁ and 110L ₂ of the fixing element 110, intended to hold against the fixing element 110 a piece of luggage placed on the support element 120 by tightening , and thus secure the luggage during a bicycle trip. The invention is of course not limited to the use of a single strap, and several straps, installed horizontally and/or vertically or diagonally can be used to hold the luggage. A tie-down net can also be used, for example to hold several small pieces of luggage, as well as a waterproof fabric to protect the luggage from the rain.

There illustrates a bicycle 1 equipped with the folding carrying structure 100, luggage 170 being placed on the support element 120 and attached to the fixing element 110 by means of the strap 160.

There illustrates a second embodiment of the invention which differs from the first mode only with regard to attachment to the bicycle. In the first mode, the structure 100 is attached to a luggage rack attached to a bicycle. In this second embodiment, the structure 200 is rigidly attached to the rear luggage rack 210, which is configured to also be rigidly mounted on a seat tube of a bicycle by means of a clamping device 220. The clamping element 220, considering the rigidity of the assembly, constitutes a pivoting blocking element of the support element 120.

With regard to the other aspects of the structure 200, we can refer to the first embodiment, with the exception of the recess 116R which has no reason to exist in this second embodiment since the fixing is done on the seat tube.

In order to facilitate the description of the structures 100 and 200 and their use, they have been described as mounted on a bicycle. Before assembly, they can be found in the form of kits to be assembled including all the elements and parts necessary for their installation on a bicycle.

Of course, the invention is not limited to the implementations described above and alternative embodiments can be made without departing from the scope of the invention as defined by the claims.
