Abstract

The present invention is formed from the development of a die-cut cardboard sheet with fold lines intended to form in the framework a prismatic column with an internally reinforced isosceles trapezoidal base, the lower area of which includes a window (11) at the core of which recesses (9) are defined which delimit multiple seats for the selective fitting of the tube of the steering stem of the bicycle framework (10). In its upper area, the column includes a plurality of through holes (17) in the larger lateral surfaces (2) and that are able to selectively face the hole (19) for passage of the axle of the rear wheel of the bicycle framework to be stabilised, which will be stabilised in the corresponding hole through said axle. In this manner, and depending on the multiple holes and seats offered by the stand, said stand can be adapted to different frame sizes and designs.

Description

UNIVERSAL SUPPORT FOR BICYCLE FRAMES

DESCRIPTION

TECHNIQUE SECTOR

The present invention refers to a device that has been specially designed to allow bicycle frames to be packaged so that they are perfectly immobilized and protected within the corresponding box.

OBJECT OF THE INVENTION

The object of the invention is to provide a multifunctional, economical device, obtained from a single piece of die-cut cardboard, which depending on its position allows it to adapt to either end of the bicycle frame, regardless of the model and size of the bicycle. the same stabilizing it completely safely within a packaging.

BACKGROUND OF THE INVENTION

In the scope of practical application of the invention, that of bicycles, whether conventional or electric, it is common for each manufacturer to design their own bicycle frames, as well as optionally other components, turning to other manufacturers for other components such as brakes, transmission, suspensions, etc.

This means that the bikes are assembled in stores or distribution warehouses, with the frames being transported to these places independently.

The reality is that there are countless bicycle models with substantially different frames that make it very difficult to develop a support that is valid for any bicycle frame, which is why specific supports are normally used for each frame model.

Obviously this means clearly undesirable packaging costs. DESCRIPTION OF THE INVENTION

The universal support for bicycle frames that the invention proposes completely satisfactorily solves the problem previously explained, offering an element adaptable to any model and size of bicycle frame, said support being valid both for stabilizing the bike frame at the level of its steering head, as well as the implantation area of the rear wheel axle on the rear triangle of the frame.

To this end, the device of the invention is constituted from the development of a sheet of die-cut cardboard with folding lines that when assembled forms a prismatic column, in which two operational areas are defined, depending on the end of the frame of the bicycle to which you want to link the device.

The first area, located in the lower area of the column, is intended to receive the head tube tube of the bicycle frame, materializing in an essentially rectangular window, elongated vertically, that gives access to the interior of the column. in which inclined gussets or ribs are formed with a plurality of protuberances between which the steering head tube selectively fits, thus adapting to different inclinations of the head tube.

For its part, in the upper area of the column, in correspondence with its sides, a matrix of through holes is established.

These holes are distributed according to the different relative positions that the rear triangle area of the bicycle frame that receives the wheel axle can adopt depending on the model in question, so that by using the axle itself the wheel, the frame can be stabilized to the support by passing it through the appropriate hole in the support as well as in the frame.

According to another of the characteristics of the invention, the column will have a configuration in plan that is not rectangular, but isoscelic trapezoidal, that is, it is divergent in a posterior direction, which allows it to be adapted in a wedge-like manner to different widths of hubs, or whatever. which is the same, to different separations between the two rear triangles that participate in the frame, thus giving greater stability to it, both vertically and laterally. In this sense, the column that determines the support will present in correspondence with its upper and lower bases some tabs that protrude with respect to the plan of the column, according to the width of the box in which the painting is going to be inserted, in order that the assembly is perfectly stabilized within said box. These tabs could be complemented with other tabs with the same purpose, emerging from the lower middle area of the support.

As mentioned above, manufacturers not only develop bicycle frames, but occasionally other specific parts for said frame, so that the set described in this way can be complemented with a tray that will be placed superiorly supported on both end supports. , with a width according to the width of the box and that defines a housing for small parts or tools that are necessary for the final assembly of the bicycle.

In this way, a device is achieved that allows it to be adapted to all types of frame models and bicycle sizes, with a universal character that significantly reduces the packaging costs of this type of frame, without compromising the safety/protection of the frame during its transport. transport.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the figures reviewed, and especially figures 1 to 5, it can be seen how the device of the invention is constituted from the development of a die-cut cardboard sheet with fold lines in which a central sector is defined. rectangular determinant of the front (1) of the column that will form the device, front (1) from which two rectangular sectors emerge laterally determining the larger side walls (2), which in turn extend into respective rectangular sectors ( 3) of smaller width and that between the two define the posterior face of the column, these sectors in turn extending into respective intermediate (4) and extreme (5) sectors that fold on themselves, reinforcing the internal structure of the column , defining in the assembly a prism with an isoscelic trapezoidal plan, these intermediate (4) and extreme (5) sectors being affected by a notch (6) in its lower middle area in which an upper horizontal profile (7) and a inclined “L” lower profile (8), in whose lower branch multiple recesses (9) are established for selective fitting of the steering head tube of the bicycle frame (10). The end sectors (5) are finished laterally with tabs (12) that fit into slots (13) provided in the area where the rectangular sectors (3) meet the intermediate sectors (4).

The device is stabilized superiorly and internally by means of two upper (14) and lower (14') rectangular sectors, which emerge from the upper and lower ends of the front (1), which have a width according to the width of the box in the which the bicycle frame-support assembly is going to be inserted, and which end at their free end in a sector that folds perpendicularly and is provided with fixing tabs (15) that fit into vertical slots (16) provided in correspondence with the upper and lower edges of the major side walls (2) and intermediate sectors (4), as well as the lower edges of the end sectors (5).

Thus, and as has just been said, in the assembly of the support, in correspondence with the lower area of the rear face, a rectangular window (11) will be defined formed by the cutouts (6), for access to the pipe tube. direction of the bicycle frame in an inverted position, as shown in figures 4 and 5, tube that will selectively stabilize the vertical branch of the “L” profile (8), as well as on the recess (9) to which it best adapts .

For its part, the upper area of the column that forms the support will be affected by a plurality of through holes (17) that affect its largest lateral faces (2), intermediate sectors (4) and end sectors (5).

These holes in the assembly of the support define a matrix of holes that can be used selectively, distributed according to the different relative positions that the rear triangle area (18) of the bicycle frame can adopt, and more specifically the hole (19) of said frame that receives the wheel axle, so that by using the wheel axle itself (not shown in the figures) the frame can be stabilized to the support by passing it through the hole (19) of the frame as well as the hole (17) suitable support, thus adapting to countless models of bicycle frames.

As previously stated, the isoscelic trapezoidal plan configuration of the device allows it to be adapted as a wedge to different widths of hubs, since this measurement is no longer standardized, so that it not only provides stability vertical to the whole, but also horizontal.

As for the side walls (2), these may have "II" notches facing each other in the area of confluence with the front (1), determining vertical tabs (20) that fold outwards, as spacer and stabilizing elements. Width according to the internal width of the box in which the entire frame-support set will be included. Equivalent vertical flanges (20') can be established in correspondence with the lateral bottom of the notches (6), thus emerging from the column pairs of vertical flanges (20-20') parallel to each other and at the same height of the column.

The device thus described can be used both to support the steering head tube and the rear triangle at the level of the wheel implantation axis, so that, once the set of frame supports is inserted into the corresponding box, it The set can be optionally complemented with a tray like the one shown in Figures 6 to 8, intended to receive other parts and/or tools necessary for assembling the bicycle.

This tray is constituted from the development of a die-cut cardboard sheet that has an "H" configuration, whose side branches are divided into two parallel sectors intended to fold 90° relative to each other, so that the outer sector (21) that In operational situation it adopts a vertical arrangement, it is intended to come into contact with the vertical and larger side walls of the box or final packaging, while the interior sectors (22) rest on the upper base of the supports of the invention, defining a intermediate sector between these shorter branches, specifically the total length of the box minus the length of the two supports between which this sector is arranged, in which two longitudinal folding lines (23) are defined that allow adopt to the tray in said area included between the supports a "U" configuration, in which the central sector (24) arranged between these two folding lines defines a horizontal surface for receiving the pieces in question, counting in its middle area with a central window (25) and some die-cuts (26) that define upper folding sectors (27) that fit on the side walls of the tray through tabs (28) that fit into slots (29), determining a opening for passage through the tray of prominent elements of the frame, such as the tube intended to receive the seat post.
