The first and the second bracket (101, 102) are pivotable connected to each other, and the spring (105) is located between the locking member (103) and the abutment member (104). In a first mode of operation (M1), the locking member (103) is displaced towards the abutment member (104) such that the spring (105) is compressed, and such that the first and second bracket (101, 102) are pivotable in relation to each other. In a second mode of operation (M2), the locking member (103) is displaced towards the first bracket (101) by the spring (105), such that the locking member (103) overlaps the first and the second bracket (101, 102) and prevents pivoting. The disclosure further relates to a vehicle (200).

Description

A pivotable connection device and a vehicle

Technical field

The present disclosure relates to a pivotable connection device and a vehicle. More specifically, the disclosure relates to a pivotable connection device and a vehicle as defined in the introductory parts of claim 1 and claim 9.

Background art

A problem with the solutions of the prior art is that they are not user friendly. For example, solutions of prior art is not suitable for certain harsh condition, e.g. cold weather wherein the user maneuvering the pivotable connection is wearing gloves. Another example indicating the problem of prior art is the lack of a smooth maneuvering procedure, which make it difficult for a user to pivot a protruding object connected to a pivotable connection without using unnecessarily amount of force, which is not desirable in certain situations. There is thus a need for improved pivotable connection.

Summary

It is an object of the present disclosure to mitigate, alleviate or eliminate one or more of the above-identified deficiencies and disadvantages in the prior art and solve at least the above mentioned problem.

According to a first aspect there is provided a pivotable connection device, for protruding objects which comprises a first bracket and a second bracket, and an locking member, which encloses an outer periphery of the second bracket and is displaceable in a first direction along the outer periphery of the second bracket, a spring, and an abutment member attached to and projecting from the outer periphery of the second bracket, and forming a first abutment surface against which the spring abuts, wherein the first bracket and the second bracket are pivotable connected to each other, and wherein the spring is located between the locking member and the abutment member, and wherein, in a first mode of operation, the locking member is displaced towards the abutment member such that the spring is compressed, and such that the first bracket and a second bracket are pivotable in relation to each other, and, wherein, in a second mode of operation, the locking member is displaced towards the first bracket by the action of the spring, such that the locking member overlaps both the first bracket and the second bracket and prevents pivoting of the first bracket in relation to the second bracket. This has the advantage of a smooth pivotable connection which is easy to maneuver by a user.

According to some embodiments, the locking member comprises a ring having an inner diameter corresponding to the outer diameter of the first and second brackets in the region of the first bracket and the second bracket where the locking member is displaceable between the first mode of operation and the second mode of operation.

According to some embodiments, one of the first bracket and the second bracket comprises one arm, and the other of the first bracket and the second bracket comprises two arms, wherein each of the arms comprises a through hole, and wherein said through holes are in alignment with each other and wherein the connection comprises a pin extending through said through holes.

According to some embodiments, the locking member comprises a protruding edge configured to enable a user of gripping the protruding edge and displacing the locking member from the second mode of operation to the first mode of operation.

According to some embodiments, the spring is a coil spring.

According to some embodiments, pivotable connection device comprises a second abutment surface provided on an opposite side of the spring in relation to the abutment member, and configured to prevent the locking member from being displaced beyond the first mode of operation in a direction away from said abutment member.

According to some embodiments, the second abutment surface is an increasing outer peripheral measure on at least of the first bracket and the second bracket increasing in the direction away from the abutment member. In other words, at least of the first bracket and the second bracket is having a conical shape. This is advantageously since the locking member will connect to the second abutment surface in a smooth way. In other words, the locking member will gradually attach around the first and second brackets during the transition from the first mode of operation (i.e. the pivotable mode) to the second mode of operation (i.e. the locked mode).

According to some embodiments, the locking member has an inner periphery measure which is increasing away from the abutment member. This is advantageously since the locking member will connect to the second abutment surface in a smooth and seamless operation, similar to the embodiment mention above. If combining the two latter embodiments, i.e. the second abutment surface being an increasing outer peripheral measure on the first bracket and/or the second bracket increasing in the direction away from the abutment member, and wherein the locking member has an inner periphery measure which is increasing away from the abutment member. The transition back and forth the two modes of operation will be particularly smooth and seamless, both with respect to the pivoting of a protruding object as well the locking and unlocking procedures.

According to a second aspect there is provided a vehicle comprising a vehicle body, a protruding object, a pivotable connection device, according to any of the first aspect. The first bracket is mounted on the vehicle body, and the second bracket is attached to the protruding object. In scenario when a vehicle has one of more protruding objects mounted on a vehicle it desirable to fold the protruding objects. It is especially advantageously if the pivot procedure is easy to maneuver, and that the pivot procedure is smooth.

According to some embodiments, the vehicle is a military vehicle.

According to some embodiments, the protruding object is an antenna.

Effects and features of the second aspect are to a large extent analogous to those described above in connection with the first aspect. Embodiments mentioned in relation to the first aspect are largely compatible with the the second aspect.

The present disclosure will become apparent from the detailed description given below. The detailed description and specific examples disclose preferred embodiments of the disclosure by way of illustration only. Those skilled in the art understand from guidance in the detailed description that changes and modifications may be made within the scope of the disclosure.
