Description

Technical Field

[0001] This invention relates to a bicycle bracket, and more particularly to a roof-mounted bicycle bracket. Background Technology

[0002] Rooftop bicycle racks are commonly used for transporting bicycles in passenger vehicles. For this purpose, a support structure is fixed to a rooftop, allowing the corresponding bicycle rack to be attached. Such bicycle racks typically include longitudinally extending profile rails and carry at least one, and particularly two, wheel retainers through which the bicycle wheels can be secured to the rack. To accommodate bicycles of different sizes, at least one wheel retainer can be moved longitudinally relative to the profile rails.

[0003] Even though this type of bicycle carrier has proven its capabilities in principle, it is sometimes argued that when the bicycle carrier is not in use, this type of bicycle carrier with profile rails that support two wheel holders cannot be transported in a space-saving manner, which is a disadvantage because the profile rails are relatively long. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide an alternative bicycle bracket that can be easily transported when the bicycle bracket is not in use.

[0005] This objective is achieved by a bicycle bracket, particularly a roof-mounted bicycle bracket, having a base body defining a longitudinal direction and including a fixing device for securing a first wheel (particularly the front wheel of the bicycle), and a sliding profile movably fixed to the base body so that it can move longitudinally relative to the base body, and having a fixing device for securing a second wheel, particularly the rear wheel of the bicycle.

[0006] This invention is based on the consideration of creating a bicycle bracket with a sliding profile that can move relative to the base body. Therefore, when the bicycle bracket is in use, the sliding profile extends rearward from the base body and carries a corresponding fixing device for securing the second wheel of the bicycle. When the bicycle bracket needs to be transported, the sliding profile can be moved forward to significantly shorten the overall length of the bicycle bracket when not in use. Preferably, the base body and the fixing device for securing the first wheel, especially the front wheel of the bicycle, are formed as a single unit, while the sliding profile can move relative to the base body.

[0007] Specifically, the base body may include a base profile that engages with a sliding profile, such that the sliding profile is fixed to the base profile perpendicular to the longitudinal direction, but can move longitudinally relative to the base profile. In other words, the two profiles, namely the base profile and the sliding profile, engage with each other, particularly in a form of form-fitting engagement, so that the sliding profile is supported on the base profile and can move longitudinally relative to the base profile.

[0008] According to a preferred embodiment, the base profile has a substantially rectangular cross-section. Correspondingly, the sliding profile may have a U-shaped cross-section that opens towards the bottom and surrounds the base profile from the top. To guide the sliding profile on the base profile, the upper side of the base profile may have a longitudinally extending guide depth. Preferably, the guide depth has sloping sidewalls such that the guide depth widens upward. Accordingly, the sliding profile may include corresponding guide protrusions that engage with the guide depth, the guide protrusions having a shape complementary to the shape of the guide depth. Thus, the sliding profile is positioned relative to the base profile by the shape-fitting engagement of the guide protrusions with the guide depth.

[0009] Furthermore, the base profile may include a rectangular guide groove centrally located within the guide depth, and the sliding profile may have two downwardly extending L-shaped protrusions at the center of the guide protrusion, forming a T-shaped engagement groove in the bottom-opening sliding profile. This T-shaped engagement groove can be used to lock the sliding profile relative to the base profile. Therefore, a locking mechanism can be provided to lock the sliding profile relative to the base profile.

[0010] Specifically, the locking mechanism may include a slotted nut arranged in an engagement groove of the sliding profile. The slotted nut can be connected to a threaded pin that passes through a corresponding through-hole formed in the base body and extends downwards so that the threaded pin protrudes downwards from the base profile. A clamping nut may be provided, which can be screwed onto the threaded pin so that the sliding profile can be supported on the base profile between the slotted nut and the clamping nut. In this way, a force-fit fixation of the sliding profile relative to the base profile can be achieved longitudinally. It is also conceivable to use a clamping screw, screwed directly into the corresponding internal thread formed in the groove.

[0011] To increase the mechanical stability of the sliding profile relative to the base profile, the base profile may have T-shaped fixing grooves on both sides, and the sliding profile may have corresponding elongated fixing protrusions on its transverse U-shaped legs, each fixing protrusion having an L-shaped cross-section that engages with the rear of the fixing groove. This allows for a shape-fitting engagement between the sliding profile and the base profile. In particular, it prevents the sliding profile from unintentionally separating from the base profile. Furthermore, a support device may be provided to limit the movement of the sliding profile relative to the base profile in the forward and / or backward directions and / or prevent the sliding profile from being completely pulled off the base profile.

[0012] To secure a bicycle wheel, particularly the rear wheel, the securing device may include a wheel retainer fixed to a sliding profile so as to be longitudinally movable relative to the sliding profile. Specifically, the wheel retainer may include a wheel retainer body that forms a form-fit with the sliding profile so that the wheel retainer body is longitudinally movable relative to the sliding profile but fixed to the sliding profile perpendicular to the longitudinal direction. Preferably, the wheel retainer body includes an engagement profile on its underside that can directly contact a corresponding opposing profile of the sliding profile. Specifically, the wheel retainer body may have a U-shaped form, opening downwards and surrounding the sliding profile. The upper side of the sliding profile may have a concave outer profile, and the wheel retainer body may have a corresponding convex profile facing downwards so that the wheel retainer body can be placed on the sliding profile and guided by the engagement of the convex profile with the concave upper profile of the sliding profile. Furthermore, corresponding engagement protrusions may be provided on both sides of the wheel retainer body, engaging inwardly into corresponding engagement grooves in the sliding profile.

[0013] This design is based on the consideration of providing a wheel retainer that can move freely in the longitudinal direction relative to the sliding profile. It does not need to be fixed to the sliding profile because the position of the wheel retainer relative to the sliding profile depends on the length of the bicycle to be connected. The arrangement of the fixing device for securing the first wheel to the base body allows it to determine the fixed position of the first wheel, and the position of the wheel retainer on the sliding profile is determined by the distance between the first and second wheels of the bicycle. Thus, it is unnecessary to lock the wheel retainer to the sliding profile.

[0014] A tensioning device can be provided in a commonly known manner to secure a bicycle wheel to a wheel cage. This tensioning device may include a tension band, one end of which is fixed to the wheel cage body and can be laid around the bicycle wheel, and the other end of which is releasably connected to the wheel cage body so that the bicycle wheel can be secured to the wheel cage. A stop device may be provided to limit the movement of the wheel cage relative to the sliding frame in the forward and / or rearward directions.

[0015] To secure another wheel, particularly the front wheel of a bicycle, to the base body, the securing device may include two fixing yokes fixed to the base body to surround the first wheel of the bicycle. The front fixing yoke surrounds the bicycle wheel from the front, and the rear fixing yoke surrounds the wheel from the rear, so that the first wheel of the bicycle can be securely fixed to the base body in a suitable manner. This design is based on the consideration of clamping the first wheel of the bicycle between the two fixing yokes from both sides. The fixing yokes preferably have a U-shaped structure, with two U-shaped legs fixed to the base body, and the central portion designed to contact the bicycle wheel. The length of the fixing yokes can be varied to adapt to the size of the bicycle wheel to be connected. Preferably, the front fixing yoke is designed to allow for length variation.

[0016] For this purpose, the U-shaped legs and central portion of the front and / or rear fixed yokes can be formed as separate elements. The central portion element can be slidably supported or fixed to the U-shaped leg elements. Specifically, the central portion may include two through openings through which the U-shaped leg elements extend. A blocking device can be provided to block the central portion relative to the U-shaped leg elements. At least one U-shaped leg element, and in particular two U-shaped leg elements, can carry a stop tooth, and a corresponding engaging device formed at the central portion element can engage with the stop tooth. It is also conceivable that the design of the front and / or rear fixed yokes prevents their length from changing.

[0017] Specifically, on the base body, particularly at the front end, the front fixing yoke is movably (especially pivotally) supported between a use position and a transport position. In the use position, the front fixing yoke is positioned relative to the base body and the bicycle wheel can push against it. In the transport position, the front fixing yoke extends substantially longitudinally and preferably rests on a sliding profile to allow for space-saving transport. Thus, in the use position, the front fixing yoke can extend upward from the base profile. Preferably, the front fixing yoke is arranged such that in its use position, the front fixing yoke forms an angle of at least 40°, especially at least 50°, and / or a maximum of 80°, especially a maximum of 70°, preferably 60°, relative to the longitudinal direction.

[0018] According to a preferred embodiment, the rear fixed yoke is movable, particularly pivotally fixed to the base body, especially at the front end of the base body, so that when the bicycle is pushed against the front fixed yoke, the rear fixed yoke can move against the bicycle wheel; and a stop is provided to lock the rear fixed yoke when it contacts the bicycle wheel. In other words, once the bicycle wheel is pushed against the front fixed yoke, the rear fixed yoke can move to contact the bicycle's first wheel to secure the wheel between the front and rear fixed yokes.

[0019] The stopping device may include a sliding element that is slidably supported longitudinally on a base body, particularly on a base profile, wherein the sliding element is connected to a rear fixed yoke such that translational motion of the sliding element relative to the base body is converted into pivotal motion of the rear fixed yoke relative to the base body. The profile of the sliding element may be formed to resemble the profile of the sliding profile so that the sliding element can engage with the base profile.

[0020] To convert the translational motion of the sliding element relative to the base body into the rotational motion of the rear fixed yoke relative to the base body, the stopping device may include at least one, particularly two, stop rods, preferably arranged on opposite sides of the base body. Each stop rod is pivotally fixed to the sliding element and the rear fixed yoke, wherein the pivot axis of the stop rod relative to the rear fixed yoke is spaced apart from the pivot axis of the rear fixed yoke relative to the base body. Thus, the sliding element slidably supported on the base body, the stop rods, and the rear fixed yoke pivotally supported on the base body form a crank-slider mechanism that converts the displacement of the sliding element relative to the base body into the rotational motion of the rear fixed yoke.

[0021] To lock the sliding element relative to the base body, the stopping device may include a stopping mechanism. Specifically, the stopping mechanism may include at least one toothed member, particularly two toothed members arranged on opposite sides of the base profile, and a corresponding stopping element. These are movable at the sliding element, particularly pivotally fixed between a stopped position and a released position. In the stopped position, they engage with the toothed members of the base profile (particularly having a serrated profile), locking the sliding element relative to the base profile. In the released position, the sliding element disengages from the toothed members, allowing the sliding element to move relative to the base body. Preferably, the stopping element is biased to its stopped position, particularly by a corresponding spring element. To manually move the stopping element from the stopped position to the released position, the stopping element may include a lever. The lever and the stopping element may be integrated into a single design.

[0022] Furthermore, the base body may include a connecting device through which the bicycle bracket can be connected to a support structure, through which the bicycle bracket can be releasably connected to the roof of the bicycle. The connecting device may be configured such that the base body can be screwed onto the support structure, which preferably includes two laterally extending support beams, particularly support beams perpendicular to the longitudinal extension. It is conceivable that the bottom of the base body has a connecting groove to support the base body on such support beams using a corresponding connecting groove nut. However, other connecting mechanisms may also be used. Attached Figure Description

[0037] Figures 1 to 3 A roof-mounted bicycle bracket 1, according to the present invention, is installed on the roof 2 of a vehicle. Specifically, a support structure comprising two crossbeams 3 is provided on the roof 2 of the vehicle, and the base body 4 of the roof-mounted bicycle bracket 1 is releasably connected to this support structure. Figure 4 As shown, the front end of the base body 4 includes a base plate 5, which is fixed to the front crossbeam 3 of the support structure with screws. The base body 4 also includes a base profile 6 made of extruded aluminum profile, the front end of which is connected to the base plate 5, and the base profile 6 defines the longitudinal direction L.

[0038] The cross-section of the base profile 6 is, for example Figure 5 As shown, its cross-section is basically rectangular. On its upper side, a guide depth 7 extending longitudinally in the direction L is provided. The guide depth 7 has inclined sidewalls 8a and 8b, both inclined at approximately 40° relative to the horizontal line, so that the guide depth 7 widens upwards. A rectangular guide groove 9 is arranged in the center of the guide depth 7. Furthermore, T-shaped fixing grooves 10 are arranged on each side of the bottom profile 6.

[0039] The base body 4 (specifically, the base plate 5) supports a fixing device for securing the front wheel 11 of the bicycle 12. The fixing device includes two U-shaped fixing yokes 13 and 14, the ends of which are fixed to the base plate 5. Figure 1 , 2 As shown in Figure 3, a front fixed yoke 13 is provided to surround the front wheel 11 of the bicycle 12 from the front. The front fixed yoke 13 is pivotally supported on the base body and can be... Figures 1 to 3 The usage location shown and Figure 13 The front retaining yoke 13 moves between the transport positions shown, in which it extends substantially along the longitudinal direction L. For this purpose, both ends of the front retaining yoke 13 are screwed to retaining elements 15, which are pivotally supported on the base plate 5. The front retaining yoke 13 reaches its use position when the stop groove 15a formed in the retaining element 15 contacts the corresponding stop bolt 15b extending laterally from the base profile 6. In the use position, the front retaining yoke 14 is inclined at approximately 60° relative to the longitudinal direction L.

[0040] The length of the front fixed yoke 13 can accommodate front wheels of different sizes. To this end, corresponding teeth are provided in the two U-shaped legs of the front fixed yoke 13, and an engagement device formed at the center of the front fixed yoke 13 can engage with these teeth. The center of the front fixed yoke 13 is slidably supported on the U-shaped legs.

[0041] The rear fixed yoke 14 is designed to wrap around the wheel 11 from the rear, so that the front wheel 12 can be fixed to the base body 4 in a form-fitting manner between the front fixed yoke 13 and the rear fixed yoke 14. The rear fixed yoke 14 is pivotally supported on the base plate 5 so that when the bicycle 12 is pushed onto the front fixed yoke 13, the rear fixed yoke 14 can be moved against the front wheel 11 of the bicycle 12. The pivoting movement of the rear fixed yoke 14 is as follows: Figure 2 and 3 As shown. In Figure 2 In the middle, the central part of the U-shaped leg of the fixed yoke 14 after connection does not contact the front wheel 11 of the bicycle, wherein, in Figure 3 In the middle, the rear fixed yoke 14 rotates upward, so that the rear fixed yoke 14 contacts the front wheel 11 of the bicycle 12.

[0042] like Figure 3 As shown, a stop device is provided to lock the rear fixed yoke 14 when it contacts the front wheel 11 of the bicycle 12. For this purpose, the stop device includes a sliding element 16 that is slidably supported on the base profile 6 in the longitudinal direction L. Figure 4 and Figure 5 As shown, the sliding element 16 is formed to completely surround the base profile 6. Specifically, the inner contour of the sliding element 16 is at least partially complementary to the outer contour of the base profile 6. Accordingly, the sliding element 16 has a guide protrusion 17 that is complementary to the guide depth 7 of the base profile 6.

[0043] The sliding element 16 is connected to the rear fixed yoke 14, thereby converting the translational motion of the sliding element 16 relative to the base profile 6 into the pivotal motion of the rear fixed yoke 14 relative to the base body 4. For this purpose, the stopping device includes two stop rods 18 arranged on opposite sides of the base profile 6. Each stop rod 18 is pivotally supported on the sliding element 16 about a corresponding first pivot axis X. Furthermore, each stop rod 18 is pivotally supported on the rear fixed yoke 14 about a second pivot axis Y, which is spaced apart from the first pivot axis X. Therefore, as... Figure 2 and Figure 3 As shown, the sliding element 16 can be moved forward relative to the base profile 6, and the fixed yoke 14 can be rotated upward.

[0044] The stopping device also includes a stopping mechanism by which the sliding element 16 can be locked relative to the base profile 6. The stopping mechanism includes two toothed members 19, the serrated profiles of which are arranged on opposite sides of the base profile 6. Specifically, the toothed members 19 are formed by two racks 20, which are arranged in the fixing groove 10 at the front of the base profile 6.

[0045] The stopping mechanism also includes two stopping elements 21, which are pivotally supported on the sliding element 16 about a vertically extending pivot axis. In corresponding support holes 22 formed in the sliding element 16, the stopping elements 21 are pivotally supported between a stopped position and a released position. In the stopped position, the stopping elements 21 engage with the toothed members 19 of the base profile 6 (e.g., Figure 6 and 7 As shown), in the released position, the stop element 21 disengages from the toothed member 19 (as shown). Figure 8 and 9 (As shown). In the stopped position, the sliding element 16 is locked relative to the base profile 6 at least in the rearward direction to prevent accidental movement of the rear fixed yoke 14. In the released position, the sliding element 16 is movable relative to the base profile 6. The stop element 21 is biased towards its stopped position and includes a lever 23.

[0046] The bicycle bracket 1 also includes a sliding profile 24 that engages with a base profile 6, thereby fixing the sliding profile 24 perpendicular to the longitudinal direction L on the base profile 6, but allowing it to move relative to the base profile 6 in the longitudinal direction L. It can move relative to the base profile 6 so that it extends beyond the rear end of the base profile 6 during use. Figures 1 to 3 When the bicycle carrier 1 is not in use and is to be transported, the sliding profile 24 can move forward relative to the base profile 6 until the sliding profile 24 contacts the rack 20 provided in the fixing groove 10 of the base profile 6.

[0047] The sliding profile 24 has a U-shaped cross-section that opens towards the bottom and surrounds the bottom profile 6 from the top. It also includes a corresponding guide protrusion 25 that engages with the guide depth 7 of the base profile 6 and has a shape complementary to that of the guide depth 7. In other words, the guide protrusion 25 is shaped to make flush contact with the sidewalls 8a, 8b of the guide depth 7.

[0048] At the center of the guide protrusion 25, the sliding profile 24 has two L-shaped protrusions 26 that extend downward and face each other to form a bottom-facing T-shaped engagement groove 27 in the sliding profile 14.

[0049] In addition, the sliding profile 24 has two elongated fixing protrusions 28 on each of its two transverse U-shaped legs, each fixing protrusion having an L-shaped cross section and facing away from each other, so that they engage behind the corresponding fixing grooves 10 formed in the base profile 6.

[0050] A locking mechanism is provided to lock the sliding profile 24 relative to the base profile 6. The locking mechanism is as follows: Figure 12As shown. It includes a slotted nut 29 arranged in an engagement groove 27 of the sliding profile 24. The slotted nut 29 is connected to a threaded pin 30, which passes through a corresponding through hole 31 formed in the base profile 6. The threaded pin 30 protrudes downward into the base profile 6. A clamping nut 32 is provided that can be screwed onto the threaded pin 30 to secure the sliding profile 24 to the base profile 6 between the slotted nut 29 and the clamping nut 32. For this purpose, the clamping nut 32 has an external shape so that it can be easily rotated by hand.

[0051] The sliding profile 24 carries a fixing device at its rear end for securing the rear wheel 33 of the bicycle 12. The fixing device includes a wheel retainer 34 supported on the sliding profile 24 so that it can move relative to the sliding profile 24 in the longitudinal direction L. Specifically, the wheel retainer 34 includes a wheel retainer body 35 having a wheel receiving depth 36. The wheel retainer body 35 is form-fitted with the sliding profile 24 so that the wheel retainer body 35 can move relative to the sliding profile 24 in the longitudinal direction L, but is fixed to the sliding profile 24 perpendicular to the longitudinal direction L.

[0052] The wheel cage 34 also includes a tensioning device 37, by which the rear wheel 33 of the bicycle 12 can be secured to the wheel cage body 35. The tensioning device 37 includes a tensioning band 38, one end of which is fixed to the wheel cage body 35 (and can be laid around the rear wheel 33), and the other end can be releasably connected to the wheel cage body 35 so that the rear wheel 33 can be secured to the wheel cage body 35.

[0053] When the bicycle is to be connected to the aforementioned top plate bicycle bracket 1, the front wheel 11 of the bicycle can be moved first until it contacts the fixed front yoke 13.

[0054] Subsequently, by moving the sliding element 16 forward, the rear fixed yoke 14 can be moved upward. The translational motion of the sliding element 16 in the longitudinal direction is converted into the pivoting motion of the rear fixed yoke 14 by the stop rod 18. Due to the sawtooth profile of the toothed member 19, the sliding element 16 can move forward without placing the stop element 21 in its released position. On the other hand, since the stop element 21 engages with the corresponding toothed member 19, the sliding element 16 cannot move backward.

[0055] This allows the bicycle's position relative to the bicycle carrier 1 to be determined. The sliding profile 24 can move relative to the base profile 6 so that the rear wheel 33 can be positioned above the sliding profile 24. The sliding profile 24 can be locked relative to the base profile 6 via a locking mechanism. The wheel retainer 34 can be positioned below the rear wheel 33 because the wheel retainer 34 can move freely relative to the sliding profile 24. The rear wheel 33 can be secured to the wheel retainer 34 by placing a tension band 38 around it.

[0056] In this way, the bicycle bracket 1 can easily accommodate bicycles of different sizes. In addition, the bicycle bracket 1 is easy to transport because when the bicycle bracket 1 needs to be transported, the sliding profile 24 can be moved forward to reduce the total length of the bicycle bracket 1 when it is not in use.
