[0001] RAMP LOCKING ARRANGEMENT FOR A RAMP OF A VEHICLE

[0002] TECHNICAL FIELD

[0003] The present invention relates to a ramp locking arrangement configured to lock a ramp of a vehicle. The present invention also relates to a vehicle comprising such a ramp locking arrangement.

[0004] BACKGROUND

[0005] Certain vehicles comprise a ramp configured to be attached in connection to an opening of the vehicle, where the ramp is operable between an open position in which said ramp is folded down, providing a ramp function for facilitating entering into and exiting out from an inner space of said vehicle, and an essentially upright closed position where said ramp is configured to be locked by means of a locking arrangement for preventing opening of the ramp. Such vehicles may operate in certain regions such as military zones and may in certain operational situations be subjected to mines in the terrain. If such a vehicle is subjected to a mine explosion underneath the vehicle, the locking arrangement may be damaged, causing the ramp to open.

[0006] There is thus a need for providing a ramp locking arrangement for locking a ramp of a vehicle, which facilitates preventing or reducing such damage.

[0007] OBJECTS OF THE INVENTION

[0008] An object of the present invention is to provide a ramp locking arrangement configured to lock a ramp of a vehicle, which facilitates preventing or reducing damage of said arrangement if the ramp is subjected certain force in the locked position.Another object of the present invention is to provide a vehicle with such a ramp locking arrangement.

[0009] SUMMARY

[0010] Specifically, an object of the invention is achieved by a ramp locking arrangement for locking a ramp of a vehicle. Said vehicle comprises a vehicle body and a ground engaging arrangement for facilitating moving the vehicle, said ground engaging arrangement being connected to said vehicle body. Said vehicle body comprises said ramp and a vehicle hull. Said ramp is configured to be attached in connection to an opening of said hull. Said ramp is operable between an open position in which said ramp is folded down, providing a ramp function for facilitating entering into and exiting out from an inner space of said vehicle via said opening, and an essentially upright closed position in which said opening is closed. Said ramp locking arrangement comprises a locking member comprising an attachment member configured to provide attachment of said locking member to said vehicle hull in connection to said opening. Said locking member further comprises an engagement member, said engagement member being connected to said attachment member so that it is movable between a locked position and an unlocked position so that said engagement member, in the locked position when said ramp is in the closed position, is configured to be engaged in connection to said ramp, preventing opening of said ramp to said open position, and, in the unlocked position, allows opening of said ramp to said open position. Said locking arrangement is configured such that said engagement member, in the locked position, is configured to be engaged in connection to said ramp such that an upward movement of the ramp relative to said locking member is allowed, said upward movement being associated with the upright position of said ramp. Said ramp locking arrangement is configured to lock a ramp of a vehicle. According to an aspect of the present disclosure, said vehicle is an armoured vehicle. According to an aspect of the present disclosure, said vehicle is tracked vehicle. According toan aspect of the present disclosure, said vehicle is a combat vehicle. Said ramp locking arrangement, when thus arranged to the hull and ramp connected to the hull, provides a deterministic, engineered system for decoupling vertical acceleration vectors caused by mine explosions from the structural integrity of the hull-ramp interface. The opening of said hull provides a hull frame in connection to which said ramp is arranged in the closed position. When a mine detonates under a vehicle, e.g. a tracked armoured vehicle, the hull is subjected to a substantial vertical acceleration, wherein the ramp, due to its inertia and mounting points, i.e. connection, may not accelerate at the exact same rate or phase as the hull, creating a differential vertical displacement between the ramp and the hull frame. According to an aspect of the present disclosure, the locking arrangement defines a vertical clearance zone configured such that vertical accelerations of the ramp relative to the hull, e.g. caused by mine detonation under the vehicle, do not result in impact contact between the ramp and the locking member.

[0011] Hereby damage of the locking arrangement due to force, e.g. mine explosion under the vehicle, causing upward movement of the ramp, may be efficiently avoided / mitigated. Hereby the risk of the ramp being subjected to an undesired opening due to force, e.g. mine explosion under the vehicle, causing upward movement of the ramp, may be efficiently avoided.

[0012] According to an aspect of said ramp locking arrangement, said engagement member comprises a roller configured to be rollable about an axis, said roller, in the locked position, being configured to be engaged in connection to said ramp and roll relative to said ramp if said ramp is subjected to an upward movement, so as to facilitate said upward movement of the ramp relative to said locking member. Hereby such upward movement is allowed in an efficient way, facilitating efficient avoidance of damage of locking arrangement comprising the locking member, and hence facilitating efficient avoidance of undesired opening of said ramp.According to an aspect of said ramp locking arrangement, said engagement member comprises a slide member, said slide member, in the locked position, being configured to be engaged in connection to said ramp and slide against said ramp if said ramp is subjected to an upward movement, so as to facilitate said upward movement of the ramp relative to said locking member. According to an aspect of said ramp locking arrangement, said engagement member comprises a slide member having a bearing surface, said bearing surface of the slide member, in the locked position, being configured to be engaged in connection to said ramp and slide against said ramp if said ramp is subjected to an upward movement, so as to facilitate said upward movement of the ramp relative to said locking member. Hereby such upward movement is allowed in an efficient way, facilitating efficient avoidance of damage of locking arrangement comprising the locking member, and hence facilitating efficient avoidance of undesired opening of said ramp.

[0013] According to an aspect of said ramp locking arrangement, said engagement member is configured to be rotatably connected to said attachment member in connection to said opening so as to facilitate moving said engagement member between said locked position and unlocked position. According to an aspect, said engagement member is configured to be rotatably arranged relative to said attachment member. According to an aspect, said engagement member is configured to be rotatable relative to said attachment member about an axis orthogonal to the transversal and upright extension of said hull in connection to said opening. Hereby easy and efficient locking and unlocking and hence easy and efficient operation of the ramp between the open and closed position is facilitated.

Hereby the engagement of said engagement member is efficiently provided so that the upward movement is allowed in an efficient way, facilitating efficient avoidance of damage of locking arrangement comprising the locking member, and hence facilitating efficient avoidance of undesired opening of said ramp. Thus, the connector part of said connection member facilitates said movement of the ramp. By thus having said connector part of said connection member protruding from said ramp, avoidance of the engagement member, in the locked position, being in contact with the ramp is facilitated. In the locked state, the upward extension of the connector part is adapted so that engagement of said engagement member with said connector part when upward movement, relative to the engagement member, of the ramp together with the connection member based on a mineblast underneath the vehicle occurs.
