[0005] The reasons why the technical result cannot be achieved are the presence of the first groove of the lock and the vertical movement of the axis of rotation. In this design, when trying to move the lock from the first position to the second, a diagonal skew occurs, which complicates the release of the motorcycle.

[0006] A device is known for the immovable fixation of a motorcycle in a vertical position, intended for transporting this motorcycle on a loading surface and comprising means for locking for translational movement and means for fastening the motorcycle, rigidly connected to the said loading surface, in which the said means for fastening have the ability to interact with the means for fastening rigidly connected to the motorcycle, and in which the said locking means have the ability to rest on the front part of the rear wheel of the motorcycle (RU 2533862, published 20.11.2014).

[0007] The reasons why the technical result cannot be achieved are that the mechanism is stationary and cannot be dismantled, and the large number of protruding elements interfere with the transportation of other goods in the vehicle.

[0009] The reason why the technical result cannot be achieved is the technological complexity of manufacturing small parts of the mechanism, which require high precision processing during manufacturing, and the operational capabilities are limited, while due to the ingress of sand and dirt, corrosion and jamming of the mechanism occurs, which entails a decrease in the reliability of fixing the motorcycle during transportation.

[0010] A device is known for fastening a motorcycle to the body of a vehicle, comprising a fastening element to the body of the vehicle, a clamp to the footrest of the motorcycle, a pivoting lever is pivotally connected to said clamp, an earring is pivotally connected to the pivoting lever, which is connected to the fastening element to the body of the vehicle, wherein the axis of connection of the earring to the pivoting lever is located relative to the axis of rotation of the lever so that in the first position of the lever, the distance between the clamp to the footrest of the motorcycle and the fastening element to the body of the vehicle is less than the distance in the second position, and the smaller distance corresponds to the fixed position of the motorcycle due to the fact that tension is provided between the clamp to the footrest of the motorcycle and the fastening element fixed to the floor of the vehicle, and the second position corresponds to the released position of the motorcycle,in which the said tension is absent to enable the motorcycle to be released from the mount, characterized in that a latch is movably secured to the pivot lever, which in the first position of the pivot lever is engaged with the projection of the lock to the motorcycle footrest and is held in this position by a spring with the ability to be released from the engagement, and the latch has an inclined surface, which is located so that when the pivot lever is moved from the second to the first position, this surface is the first to come into contact with the lock, ensuring the deflection of the latch for its subsequent snapping into place with engagement, taken as a prototype (RU 238845, published 11 / 13 / 2025).,

[0011] The reason why the technical result cannot be achieved is the lack of height adjustment of the mount, which affects the reduction of the operational characteristics of the device.

[0034] Fig. 2 shows a device for attaching a motorcycle to the body of a vehicle, closed position.

[0035] Fig. 3 shows a device for fastening a motorcycle to the body of a vehicle, in the unfastened position.

[0036] The device for fastening a motorcycle to the body of a vehicle comprises an eye for fastening to the floor 1 to the body of a vehicle 7, a clamp 2 to the footrest of the motorcycle, a rotary lever 3 is pivotally connected to the said clamp 2, an earring 4 is pivotally connected to the rotary lever 3, into which a screw carabiner 11 is threaded, holding a chain 8 secured by a rigging bracket 9 to the eye for fastening to the floor 1, wherein the axis 5 for attaching the earring 4 to the rotary lever 3 is located relative to the axis 6 of rotation of the lever 3 so that when the lever 3 is moved from the first position to the second position, the distance between the clamp 2 to the footrest of the motorcycle and the body of the vehicle 7 differs by a distance H, which is shown in Fig.2, and the first position corresponds to the secured state of the motorcycle due to the fact that tension is provided between the fastener 2 to the motorcycle footrest and the body of the vehicle 7, and the second position corresponds to the released position of the motorcycle, in which the said tension is absent for the possibility of releasing the motorcycle from the fastening.

[0037] The pivot arm 3 has a safety eye 13, which in the first position of the pivot arm 3, shown in Fig. 2, passes through the fastening hole 12 in the lock 2, and is held in this position by an annular cotter pin 14, which prevents arbitrary movement from the first to the second position. The lock 2 contains a locking groove 10, shown in Fig. 3, along which the axis of the fastening of the earring 5 moves, limiting the movement in the state of tension of the motorcycle footrest with the possibility of disengagement.

[0038] The retainer 2 contains the axle for fastening the footrest 15, shown in Fig. 3, which prevents the lateral movement of the retainer 2 and ensures a secure engagement with the footrest of the motorcycle.

[0039] Implementation of a utility model

[0040] Let's consider a specific implementation of a device for attaching a motorcycle to a vehicle body. The device components are made of steel, cold-galvanized, and connected with bolts. The hinge joints are implemented by installing axles into holes in the mating components. The ring-shaped cotter pin 14 is made rigid from the same material as the other components, providing the necessary rigidity compared to the strap used in the prototype, and the required strength. This prevents its deformation and disengagement under alternating loads, as well as damage.

[0041] Let's consider an example of how to use a motorcycle mount to a vehicle body. The mount is secured to the vehicle body by floor mounting eyes 1 using a bolted connection. This can be a body or a trailer. The motorcycle is mounted on the vehicle body 7. Since the pivot arm 3 is initially in the second position, it fits easily onto the motorcycle's footrest. It is then moved to the first position, resulting in a decrease in the distance from the motorcycle to the floor by H, creating tension on the chain 8 due to the suspension's shock absorption. The motorcycle is secured by two mounts located on either side of the vehicle body, pulling it to the floor. Ring-shaped cotter pin 14 holds the pivot arm 3 in the first position, preventing the chain 8 from loosening.
