Description

[0001] The present invention relates to bicycle and motorcycle boxes including safety hinges.

[0002] A box is known in the prior art, which comprises a lid hinged in the rear area of ​​the box and locked in the front area, thus allowing the box to be opened easily. An important factor for the rear hinge is the force required for opening. The hinge can be completely free, where low rotational friction allows easy opening but the lid can only be opened or closed, while in the intermediate open position, at any tilt angle relative to the bottom, the weight of the lid will cause it to fall. Alternatively, the hinge can have high friction, with a force for opening the lid at the maximum possible angle relative to the bottom, but it can keep the lid in the intermediate open position with a freely selectable tilt angle relative to the bottom. The disadvantage of the second solution is that it is not possible to maintain a constant friction for a long time, because the friction surface will be consumed during use, thus changing its mechanical characteristics. The solution of the prior art is to insert a screw adjustment device in the pin, but this brings some difficulties: the box can be easily opened by unscrewing and removing the pin from the segmented hollow cylinder of the hinge, thus canceling the security of the box. Another disadvantage is that the threaded pin tends to rotate with the hinge and the nut will loosen, thus making the hardness adjustment of the lid opening relative to the bottom ineffective.

[0003] The object of the present invention is to create a bicycle or motorcycle box comprising a safety hinge which makes it possible to overcome the drawbacks of the prior art, prevent theft and make it possible to effectively adjust the stiffness of the opening hinge over time, allowing the lid of the box to remain open at any angle of inclination relative to the bottom and to remain in this inclined open position at a preferred angle.

[0004] According to the invention, this object is achieved by a housing according to claim 1 .

[0005] Further features are provided in the dependent claims.

[0006] The characteristics and advantages of the present invention will become more apparent from the following exemplary and non-limiting description with reference to the attached schematic drawings, in which:

[0015] The hinge 10 includes a pin 40 that pivots with a segmented upper hollow cylinder 200 and a segmented lower hollow cylinder 300 along a hinge axis.

[0016] The pin 40 comprises a screwing head 42 , a shaft 43 comprising at least one threaded portion 41 .

[0017] The hinge 10 comprises a nut 50 screwed with the at least one threaded portion 41 of the shank 43 of the pin 40 .

[0018] The hinge 10 comprises a first bushing 60 comprising a hollow body comprising a through hole 65 arranged along the hinge axis, with matching teeth 62 protruding radially outwards from the outer surface of the body of the first bushing 60 .

[0019] The hollow body of the first bushing 60 includes a first portion 64 having a smaller diameter and a second portion 66 having a larger diameter.

[0020] The hinge 10 includes a second bushing 70, which includes a hollow body including a through hole 75 arranged along the hinge axis, and matching teeth 72 protrude radially outward from the outer surface of the body of the second bushing 70, wherein the hollow body of the second bushing 70 includes a first part 74 with a smaller diameter and a second part 76 with a larger diameter.

[0021] The rod 43 of the pin 40 is installed through the through hole 65 of the first bushing 60 and the through hole 75 of the second bushing 70 .

[0022] The first segment 201 of the segmented hollow cylinder 200 comprises a through hole 260 arranged along the hinge axis. The shape and size of the through hole 260 are suitable for accommodating the body of the first bushing 60. The through hole 260 comprises a housing portion 262 having a complementary shape relative to the matching teeth 62 of the first bushing 60. The first bushing 60 is accommodated in the through hole 260 of the first segment 201 of the segmented hollow cylinder 200.

[0023] The matching tooth 62 is accommodated in the housing portion 262 of the through hole 260 of the first segment 201 of the segmented hollow cylinder 200 .

[0024] The last segment 207 of the segmented hollow cylinder 200 comprises a through hole 270 along the hinge axis. The shape and size of the through hole 270 are suitable for accommodating the body of the second bushing 70.

[0041] Advantageously, the second segment 202 of the segmented hollow cylinder 200 comprises a through hole 264 along the hinge axis, the shape and size of which are suitable for receiving at least a part of the first portion 64 of the first bushing 60 .

[0042] Advantageously, the penultimate segment 206 of the segmented hollow cylinder 200 comprises a through hole 274 along the hinge axis, which is shaped and sized to receive at least a portion of the first portion 74 of the second bushing 70 .

[0043] Advantageously, the bicycle or motorcycle box 100 of the present invention includes a safety hinge 10, which can overcome the shortcomings of the prior art, has an anti-theft function, and effectively adjusts the hardness of the opening hinge over time, allowing the lid 102 of the box 100 to remain open at any tilt angle relative to the bottom 103 and remain in this tilted open position at an angle preferred by the user.

[0044] Alternatively, the matching teeth 62 of the first bushing 60 may be provided to protrude radially outward from the outer surface of the first portion 64 of the main body of the first bushing 60 .

[0045] Alternatively, the matching teeth 72 of the second bushing 70 may be provided to protrude radially outward from the outer surface of the first portion 74 of the body of the second bushing 70 .
