Description

[0001] DOCKING SHELTER SYSTEM FOR A VEHICLE LOADING DOCK

[0002] Technical field

[0003] The present disclosure is directed generally to docking shelter systems for a vehicle loading docks.

[0004] Background

[0005] Vehicle docking facilities, such as warehouses, typically include multiple vehicle loading docks that facilitate the movement of goods between the facility and a vehicle parked at the docking station. Each vehicle docking station can include docking equipment used to improve the safety and efficiency of moving goods between the facility and the vehicle. A vehicle docking station can include, for example, a vehicle restraint used to ensure that the vehicle does not move away from the docking station during loading and unloading, a dock door used to control access into and out of the warehouse, a dock leveler used to provide a bridge or ramp between the vehicle and the facility, a barrier gate to prevent cargo or personnel from falling out of the docking station when the dock door is open, and a shelter to provide cover between the vehicle and the facility during loading and unloading.

[0006] Shelters are commonly of one of two types: inflatable or stationary. Inflatable shelters can be inflated to closely follow the outer contour of the vehicle and thereby provide an efficient sealing. However, inflatable shelters are expensive to both produce and install. Stationary shelters are usually in form of permanent structures with sealing members into which the vehicle is driven, compared to inflatable shelters such stationary shelters are significantly cheaper to produce and install however at the cost of considerably worse sealing performance.

[0007] Summary

[0008] An object of the present disclosure is therefore to provide one or more improvements in the field of docking shelter systems. According to an aspect a docking shelter system for a vehicle loading dock is provided. The docking shelter system comprises a shelter support structure, and one or more covers mounted to the shelter support structure for engaging a vehicle trailer. The docking shelter system further comprises a dock shelter operator system configured to operate the one or more covers between a deployed state wherein the one or more covers is arranged to engage the vehicle trailer and a stowed away state. This allows for a docking shelter system which may be easily adaptable to accommodate a vehicle trailer moving in and out of the vehicle loading dock and accommodate for different types of vehicle trailers positioned differently relative the vehicle loading dock.

[0009] In one example, the one or more covers comprises an upper cover, a first side cover and / or a second side cover connected to the shelter support structure and adapted to engage a upper surface, a first side surface and a second side surface of the vehicle trailer, respectively. Such covers may enable sheltering and sealing on all relevant sides of the vehicle trailer.

[0010] In one example, the dock shelter operator system is configured to operate the upper cover, the first side cover and / or second side cover between the deployed state wherein said upper cover, first side cover and / or the second side cover is arranged to engage the vehicle trailer and the stowed away state. Hence, a dock shelter operator system allowing for operation of a plurality of covers may be achieved.

[0011] The dock shelter operator system may be configured to operate the upper cover in a vertical direction between the deployed state and the stowed away state, the first side cover at least partially in a horizontal direction between the deployed state and / or the second side cover at least partially in a horizontal direction between the deployed state and the stowed away state.

[0012] In one example, a first end portion of the one or more cover is mounted to the shelter support structure and the dock shelter operator system is configured to cause movement of a second end portion opposite to the first end portion to operate the one or more cover between the deployed state and the stowed away state. Thereby the cover(s) may enable an improved shelter capable of sealing between the shelter support structure and the vehicle trailer. In one example, the dock shelter operator system comprises at least one motor and a transmission system connected to said at least one motor. The dock shelter operator system may be configured to transfer torque from the at least one motor to the one or more covers to cause operation of said one or more cover. The dock shelter operator system enables operation of the one or more covers to selectively engage a vehicle trailer and to be stowed away when desired.

[0013] In one example, the dock shelter operator system comprises one motor. The transmission system may be connected to said one motor to transfer the torque of said motor to cause the operation of the one or more cover. Thereby, a less-complex dock shelter operator system may be achieved.

[0014] The transmission system may be configured to cause operation from the stowed away state to the deployed state with a predefined number of rotations of the motor. By utilizing a predefined number of rotations of the motor, the operation of the one or more cover may be more accurate and reliable.

[0015] In one example, the transmission system may comprise a first side cover transmission arrangement comprising a first elongated side cover transmission element and a driven first side cover transmission element connected to the at least one motor and the first elongated side cover transmission element to cause movement of the first side cover. The first side cover transmission arrangement allows for a non-complex and cost-efficient transmission of torque from the at least one motor to the first side cover.

[0016] In one example, the transmission system a second side cover transmission arrangement comprising a second elongated side cover transmission element and a driven second side cover transmission element connected to the at least one motor and the second elongated side cover transmission element to cause movement of the second side cover. The second side cover transmission arrangement allows for a non-complex and cost-efficient transmission of torque from the at least one motor to the second side cover.

[0017] The first side cover transmission arrangement may comprise a first side arm arrangement operable by means of the first elongated side cover transmission element. The first side arm arrangement may comprise one or more pivotable arms connected to the first side cover. The one or more pivotable arms may be arranged such that movement of the first side cover elongated transmission element causes pivoting of said one or more pivotable arms and prompts operating of the first side cover between the deployed state and stowed away state.

[0018] The second side cover transmission arrangement may comprise a second side arm arrangement operable by means of the second elongated side cover transmission element. The second side arm arrangement may comprise one or more pivotable arms connected to the second side cover and arranged such that movement of the second side cover elongated transmission element causes pivoting of said one or more pivotable arms and prompts operating of the second side cover between the deployed state and stowed away state.

[0019] The side cover transmission arrangements allows for a more precise manner of operating the side covers and enables an improved sealing.

[0020] In one example, the transmission system comprises an upper cover transmission arrangement. The upper cover transmission arrangement may comprise one or more elongated upper cover transmission element and one or more driven upper cover transmission element connected to the at least one motor and the elongated upper cover transmission element to cause movement of the upper cover. The upper cover transmission arrangement allows for a non-complex and efficient manner of transferring the torque from the one or more motor to the upper cover.

[0021] The upper cover transmission arrangement may comprise a first elongated upper cover transmission element connected to a first driven upper cover transmission element arranged at a first side of the upper cover and a second upper cover elongated transmission element connected to a second driven upper cover transmission element at a second side of the upper cover opposite to the first side. The two upper cover transmission element may allow for an improved support for the upper cover upon operation between the stowed away state and the deployed state.

[0022] The upper cover transmission arrangement may comprise one or more upper cover engaging member. The upper cover engaging member may be suspended in one of the one or more elongated upper cover transmission element and arranged to engage the upper cover to cause operation of the upper cover. The engaging member(s) allows for easier calibration as the operation of the upper cover may be directly adapted by means of suspending the engaging member(s) at different heights.

[0023] In one example, the at least one of the one or more covers may comprise a sheet element. The sheet element may preferably be in a flexible material. This allows for a cost-efficient cover capable of providing sufficient sealing and sheltering properties.

[0024] The sheet element may comprise a plurality of interconnected sections foldable relative to each other. Such a cover with interconnected sections allows for costefficient and non-complex operation compared to inflatable covers while still providing sufficient sealing and sheltering properties.

[0025] According to an aspect a cover for a docking shelter system is provided. The cover may be adapted to be mounted to a shelter support structure of a docking shelter system for a vehicle loading dock. The cover comprises a sheet element. The sheet element allows for a more cost-efficient cover and enables reliable sealing between a vehicle trailer and the cover.

[0026] In one example, the cover may be in a flexible material. The flexible material allows for the cover to engage the vehicle trailer even in cases where the trailer has an uneven outer contour or is parked at an angle relative to the docking shelter system.

[0027] In one example, the sheet element is in a fabric material. Compared to other materials a fabric material may be more cost-efficient and more environment friendly.

[0028] In one example, the sheet element may comprise a plurality of interconnected sections. The interconnected sections may be foldable relative to each other. Due to the foldable design, the cover may be operated in a simple manner to engage a vehicle trailer, particularly compared to an inflatable cover.

[0029] In one example, at least one of the one or more covers may comprise a plurality of stiffening cross-members arranged between the interconnected sections. The crossmembers may improve the stability of the cover making it easier to operate.

[0030] In one example, the cover may be any one of an upper cover, a first side cover and a second side cover adapted to be connected to the shelter support structure and adapted to engage an upper surface, a first side surface and a second side surface of the vehicle trailer, respectively. In one example, the interconnected sections of the sheet element of the first side cover or the second side cover is arranged to extend in a vertical direction upon mounting of said cover to the shelter support structure.

[0031] In one example, the interconnected sections of the sheet element of the upper cover is arranged to extend in a horizontal direction upon mounting of said cover to the shelter support structure.

[0032] In one example, the fabric material may comprise a polymeric material such as polypropylene. Compared to PVC, a more environment friendly cover may be achieved.

[0033] In one example, the cover may comprise a profile. The profile may be provided along an outer edge portion of the sheet element. The profile may be arranged to engage a vehicle trailer. The profile may improve the stability of the cover.

[0034] In one example, the profile may comprise a rigid profile portion attached to the sheet element.

[0035] In one example, the profile may comprise a resilient profile portion. The resilient profile portion may be mounted to the rigid profile portion and may be adapted to engage the vehicle trailer. This may allow for an improved sealing.

[0036] In one example, the resilient profile portion may comprise a chamber formed by a longitudinal aperture extending along the profile. The chamber causes the resilient profile portion to be softer and more pliable, further improving the sealing properties.

[0037] In one example, the resilient profile portion may be in an elastomeric material such as rubber.

[0038] In one example, the cover further comprises an inner and outer sheet element. The inner and outer sheet element may extend parallel to and at a distance from each other. The two sheets may allow for a more stable cover with improved sealing. Further, the space between the sheets may be utilized for accommodating actuating mechanisms for the cover, improving the safety of the docking shelter system.

[0039] According to an aspect a docking shelter system for a vehicle loading dock is provided. The docking shelter system may comprise a shelter support structure and one or more covers according to any of the examples described herein. The one or more covers may be mounted to the shelter support structure for engaging a vehicle trailer. In one example, the one or more covers may comprise an upper cover, a first side cover and / or a second side cover connected to the shelter support structure and adapted to engage an upper surface, a first side surface and a second side surface of the vehicle trailer, respectively.

[0058] Detailed description of embodiments

[0059] Embodiments of the invention will now be described with reference to the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. The terminology used in the detailed description of the particular embodiments illustrated in the accompanying drawings is not intended to be limiting of the invention. In the drawings, like numbers refer to like elements.

[0060] Figure 1 schematically depicts an exemplary vehicle loading dock 10 in which the docking shelter system according to the present disclosure may be implemented. Notably, the vehicle loading dock 10 is depicted for exemplary purposes. It may be envisioned that the docking shelter system may be implemented for any plausible type of vehicle loading dock.

[0061] Typically, the loading dock 10 may comprise a door 15. As depicted, the door may be an overhead sectional door. As the skilled person is aware, an overhead sectional door is a door operable between a raised open position and a lowered closed position. The door 15 is arranged in an opening of a wall 14 and is adapted to control access through said opening. The door 15 may be operated by means of a door operator system 16.

[0062] The loading dock 10 may typically further comprise a dock leveller 12 operated by a dock leveller operator system 11. The dock leveller 12 is operable to align with a vehicle and / or vehicle trailer in order to accommodate transport of goods between the vehicle and / or vehicle trailer and the opening. In some cases, the dock leveller 12 forms a ramp between a vehicle trailer and the opening.

The control panel 13 may be operatively connected to the dock leveller operator system 11 and / or the dock leveller operator system 11 such that a user may operate the dock leveller 12 and / or the door 15 via the control panel 13.

[0064] To protect the personnel loading or unloading the vehicle and / or vehicle trailer, docking shelter systems are commonly utilized. Such systems are arranged in connection to the loading dock and around the opening. An exemplary docking shelter system 100 is arranged in connection to the vehicle loading dock 10. The docking shelter system 100 is arranged on an exterior side of the wall 14. The docking shelter system 100 may extend along a first and second horizontal side of the door 15 and along an upper side of the door 15.

[0065] According to the present disclosure, a docking shelter system 100 for a vehicle loading dock 10 is provided.

[0066] Figure 2-3 depicts aspects of a docking shelter system 100 for a vehicle loading dock 10 according to one embodiment. The docking shelter system 100 is arranged to provide shelter around a vehicle 1 upon loading or unloading of goods into the loading dock.

[0067] The one or more covers 300, 400, 500 may comprise an upper cover 500, a first side cover 300 and / or a second side cover 400.

[0068] The upper cover 500 may be adapted to engage an upper surface of the vehicle trailer 2, e.g. a substantially horizontally extending upper surface of the vehicle trailer 2. The upper cover 500 may at least in a deployed state extend in a substantially vertical direction.

[0069] The first side cover 300 may be adapted to engage a first side surface of the vehicle trailer 2, e.g. a substantially vertically extending side surface of the vehicle trailer 2. The first side cover 300 may at least in a deployed state extend in a substantially horizontal direction.

[0070] The second side cover 400 may be adapted to engage a second side surface of the vehicle trailer 2, e.g. a substantially vertically extending side surface of the vehicle trailer 2. The second side cover 400 may at least in a deployed state extend in a substantially horizontal direction.

[0071] The first side cover 300 and the second side cover 400 may be adapted to engage opposite surfaces of the vehicle trailer 2. Hence, the second side cover 400 may extend from the shelter support structure 50 in an opposite horizontal direction relative to the first side cover 300.

[0072] The first side cover 300, the second side cover 400 and the upper cover 500 may be mounted to the shelter support structure 50.

[0073] The shelter support structure 50 may comprise a frame 55. The frame 55 may be adapted to extend around the door of the vehicle loading dock. The one or more cover 300, 400, 500, e.g. the first side cover 300, the second side cover 400 and the upper cover 500, may be mounted to the frame 55.

[0074] In one embodiment, the frame 55 may comprise a first vertical frame member 52. The first side cover 300 may be mounted to the first vertical frame member 52. The frame 55 may comprise a second vertical frame member 53. The second side cover 400 may be mounted to the second vertical frame member 53. The first vertical frame member 52 and the second vertical frame member 53 may be adapted to be arranged on opposite vertical sides of the door of the vehicle loading dock.

[0075] The frame 55 may comprise a horizontal frame member 51. The upper cover 500 may be mounted to the horizontal frame member 51. The horizontal frame member 51 may be adapted to be arranged above the door of the vehicle loading dock. The horizontal frame member 51 may be connected to first and / or second vertical frame member or may be arranged independently from said first and second vertical frame member. In the depicted example, the horizontal frame member 51 interconnects the first vertical frame member 52 and the second vertical frame member 53.

[0076] The one or more cover 300, 400, 500 may engage the vehicle trailer 2 by means of being engagable by said vehicle trailer 2. Alternatively or additionally, the one or more cover 300, 400, 500 may be operable between a deployed state and a stowed away state.

[0077] Figure 2 depicts the one or more cover 300, 400, 500 in a stowed away state. In the stowed away state, the one or more covers 300, 400, 500 may be arranged adjacent to the shelter support structure 50 such that a distance may be provided between said one or more covers 300, 400, 500 and the vehicle trailer 2.

[0078] In one example, at least one of one or more covers 300, 400, 500 and at least one of the one or more covers 300, 400, 500 may be stationary. In one example, each of the one or more covers 300, 400, 500 may be operable between the deployed state and the stowed state.

[0079] The design of the one or more cover 300, 400, 500 will now be explained in further detail with reference to Figure 3a. Notably, the one or more covers 300, 400, 500 may be stationary or operable by means of the dock shelter operator system.

[0080] The one or more covers 300, 400, 500 may comprise a sheet element 340, 440, 540. Preferably, the sheet element is in a flexible material. The sheet element in the flexible material allows the cover to more closely follow the shape of the vehicle trailer 2 and thereby improve the sealing properties of the docking shelter system 100. Furthermore, it potentially reduces the complexity of the docking shelter system due to it allowing for an operator system to be less precise in terms of the operation of the covers as the flexible material allows the cover to engage different types of vehicles with different dimensions etc. without requiring complex transmission systems to adapt the operation of the covers.

[0081] A flexible material may herein refer to a non-rigid material. The non-rigid material may be adapted to deform upon engaging the vehicle trailer 2.

[0082] In one embodiment, the sheet element 340, 440, 540 may be in a fabric material. In one embodiment, the fabric material may comprise a polymeric material such as polypropylene.

Accordingly, said interconnected sections 350 may extend across the sheet element 340 in a vertical direction. The interconnected sections 450 of the sheet element 440 of the second side cover 400 may extend in a vertical direction. Accordingly, said interconnected sections 450 may extend across the sheet element 440 in a vertical direction.

[0090] The interconnected sections 550 of the sheet element 540 of the upper cover 500 may extend in a horizontal direction. Accordingly, said interconnected sections 550 may extend across the sheet element 540 in a horizontal direction.

[0091] The interconnected sections 350 of the first side cover 300 may be considered first side cover sections and the sheet element 340 of said first side cover 300 may be considered a first side cover sheet element. The interconnected sections 450 of the second side cover 400 may be considered second side cover sections and the sheet element 440 of said second side cover 300 may be considered a second side cover sheet element. Correspondingly, the interconnected sections 550 of the upper cover 500 may be considered upper cover sections and the sheet element 540 of said upper cover 500 may be considered an upper cover sheet element.

[0092] The one or more covers 300, 400, 500 may comprise a profile 380, 480, 580. The profile 380,480, 580 may be provided along an outer edge portion of the sheet element 340, 440, 540.

The rigid profile portion may be attached to the sheet element 340, 440, 540. The rigid profile portion may be in a rigid material. The rigid profile portion may be in a metal material such as aluminium or steel.

[0094] The first side cover 300 may comprise a profile 380. The profile 380 may be considered a first side cover profile 380. The first side cover profile 380 may extend vertically. The first side cover profile 380 may form an outer vertical edge of the first side cover 300. Correspondingly, the second side cover 400 may comprise a profile 480. The profile 480 may be considered a second side cover profile 480. The second side cover profile 480 may extend vertically. The second side cover profile 480 may form an outer vertical edge of the second side cover 400.

[0095] In one embodiment, the upper cover 500 may comprise a profile 580. The profile 580 may be considered an upper cover profile 580. The upper cover profile 580 may extend horizontally. The upper cover profile 580 may form a bottom horizontal edge of the upper cover 500.

[0096] Figure 3a depicts the one or more cover 300, 400, 500 in a deployed state. In the deployed state, the one or more covers 300, 400, 500 may be arranged to engage the vehicle trailer 2. Thus, the one or more covers 300, 400, 500 may be operable to a position where said one or more covers 300, 400, 500 engages the vehicle trailer 2.

[0097] For this purpose, the docking shelter system 100 may comprise a dock shelter operator system 200. The dock shelter operator system 200 may be configured to operate the one or more covers 300, 400, 500 between the deployed state and the stowed away state.

[0098] The dock shelter operator system 200 may be manually operable and / or operable by means of at least one motor 200.

[0099] The dock shelter operator system 200 may be configured to operate the upper cover 300 between the deployed state and the stowed away state, wherein the upper cover 300 is arranged to engage the vehicle trailer 2 in said deployed state.

[0100] Correspondingly, the dock shelter operator system 200 may be configured to operate the first side cover 300 and / or the second side cover 400 between the deployed state and the stowed away state, wherein first side cover 300 and / or the second side cover 400 is arranged to engage the vehicle trailer 2 in said deployed state.

[0101] Further referencing Figure 3a, the dock shelter operator system 200 may be configured to operate the upper cover 500 in a vertical direction between the deployed state and the stowed away state. The dock shelter operator system 200 may be configured to operate the upper cover 500 in said vertical direction to engage or disengage the vehicle trailer 2.

[0102] In one embodiment, the dock shelter operator system 200 is configured to operate the first side cover 300 between the deployed state and the stowed state at least partially in a horizontal direction. Hence, the dock shelter operator system 200 is configured to operate the first side cover 300 at least partially in a horizontal direction to cause the first side cover 300 to transition between the stowed state and the deployed state.

[0103] Additionally or alternatively, the dock shelter operator system 200 is configured to operate the second side cover 400 between the deployed state and the stowed state at least partially in a horizontal direction. Hence, the dock shelter operator system 200 is configured to operate the second side cover 400 at least partially in a horizontal direction to cause the second side cover 400 to transition between the stowed state and the deployed state.

[0104] Advantageously, the dock shelter operator system 200 is configured to operate the first side cover 300 in a first direction extending at least partially horizontally from the stowed away state to the deployed state and the second side cover 400 in a second direction extending at least partially horizontally from the stowed away state to the deployed state.

In one example, the dock shelter operator system 200 may be configured to operate the first side cover and / or the second side cover 400 in a direction extending both horizontally and vertically between the stowed away state and the deployed state.

[0106] Figure 3b depicts the docking shelter system 100 of Figure 2 and 3a with parts of the first side cover 300 removed to further highlight aspects of the dock shelter operator system 200.

[0107] As depicted, a first end portion 321, 421, 521 of the one or more cover 300, 400, 500 may be mounted to the shelter support structure 50 and the dock shelter operator system 200 is configured to cause movement of a second end portion 322, 422, 522 opposite to the first end portion 321, 421, 521 to operate the one or more cover 300, 400, 500 between the deployed state and the stowed away state. The first end portion 321, 421, 521 may thus be fixed relative to the shelter support structure 50 and the second end portion 321, 421, 521 may be adapted to engage the vehicle trailer 2. In one embodiment, first end portion 321, 421, 521 may be sealingly connected to the shelter support structure 50. In one example, the first end portion 321 of the first side cover 300 may be mounted to the shelter support structure 50. Preferably, the first end portion 321 may be mounted to the first vertical frame member 52. The first end portion 321 may extend in a vertical direction. Hence, the first end portion 321 may be a vertically extending first end portion 321 of the first side cover 300. The second end portion 322 of the first side cover 300 may movable by means of the dock shelter operator system 200. The second end portion 322 may be movable relative to the shelter support structure 50. Preferably, the second end portion 322 may be movable relative the first vertical frame member 52. The second end portion 322 may be a vertically extending second end portion of the first side cover 300.

[0108] In one example, the first end portion 421 of the second side cover 300 may be mounted to the shelter support structure 50. Preferably, the first end portion 421 may be mounted to the second vertical frame member 53. The first end portion 421 may extend in a vertical direction. Hence, the first end portion 421 may be a vertically extending first end portion 421 of the second side cover 400. The second end portion 422 of the second side cover 400 may movable by means of the dock shelter operator system 200. The second end portion 422 may be movable relative to the shelter support structure 50. Preferably, the second end portion 422 may be movable relative the second vertical frame member 53. The second end portion 422 may be a vertically extending second end portion of the second side cover 400.

[0109] In one example, the first end portion 521 of the upper cover 500 may be mounted to the shelter support structure 50. Preferably, the first end portion 521 may be mounted to the horizontal frame member 53. The first end portion 521 may extend in a horizontal direction. Hence, the first end portion 521 may be a horizontally extending first end portion 521 of the upper cover 300. The second end portion 522 of the upper cover 500 may movable by means of the dock shelter operator system 200. The second end portion 522 may be movable relative to the shelter support structure 50. Preferably, the second end portion 522 may be movable relative the horizontal frame member 52. The second end portion 522 may be a horizontally extending second end portion of the upper cover 500. Figure 4 schematically depicts a door operator system 200 according to an embodiment.

[0110] The docking shelter system 100 may comprise a shelter control system 900. The shelter control system 900 may be operatively connected to the dock shelter operator system 200. The shelter control system 900 may be configured to cause control of the dock shelter operator system 200. The shelter control system 900 may be configured to be operatively connected to a control input interface 903. The shelter control system 900 may be configured to obtain user input data from the control input interface 903. The shelter control system 900 may be configured to cause control of the dock shelter operator system 200 based on the user input data. The shelter control system 900 may comprise a control unit 901 for controlling the dock shelter operator system 200.

[0111] Further referencing Figure 4, the dock shelter operator system 200 may comprise at least one motor 201. The at least one motor 201 may be an electrical motor such as a brushless electrical motor. In order to transmit the torque from the at least one motor to the one or more cover 300, 400, 500 to operate the one or more covers, a transmission system 210 may be provided.

[0112] The transmission system 210 may be connected to the at least one motor 201. The transmission system 210 may be configured to transfer torque from the at least one motor 201 to the one or more covers 300, 400, 500 to cause operation of said one or more covers.

[0113] To achieve a more space-efficient shelter system, the at least one motor 201 may be arranged above the one or more cover 300, 400, 500. In the depicted example, the at least one motor 201 is arranged above the shelter support structure 50 and in particular above the frame 50. The at least one motor 201 may be configured to be mounted to a wall section of the loading dock or on top of the shelter support structure 50.

[0114] To reduce the complexity of the dock shelter operator system 200 a single motor 201 may be utilized. Accordingly, the dock shelter operator system 200 may comprise one motor 201. The transmission system 210 may be connected to said one motor 201 to transfer the torque of said one motor cause operation of the one or more cover 300, 400, 500. In the depicted example, the transmission system is configured to transfer the torque of said one motor 201 to cause operation of the first side cover 300, the second side cover 400 and the upper cover 500.

[0115] To reduce the complexity and improve the predictability of the behavior of the docking shelter system, the transmission system 201 may be arranged such that a predefined number of rotations of the one motor 201 causes operation of the one or more cover 300, 400, 500 from the stowed away state to the deployed state. The transmission system 210 may be configured to cause operation from the stowed away state to the deployed state of the one or more cover 300, 400, 500 with a predefined number of rotations of the motor 201.

[0116] Additionally or alternatively, it may be envisioned that the transmission system 201 may be arranged such that a predefined number of rotations of the one motor 201 causes operation of the one or more cover 300, 400, 500 from the deployed state to the stowed away state. The transmission system 210 may be configured to cause operation from the deployed state to the stowed away state of the one or more cover 300, 400, 500 with a predefined number of rotations of the motor 201.

[0117] Figure 4 schematically depicts the transmission system 210. In the depicted example, the transmission system 210 transfers torque to the first side cover 300, the second side cover 400 and the upper cover 500. It may however be envisioned that only one or two of the covers are operable while one or two of the covers are stationary and / or not connected to the motor 201 of the dock shelter operator system 200.

[0118] In one embodiment, the transmission system 210 comprises a first side cover transmission arrangement. The first side cover transmission arrangement comprises a first elongated side cover transmission element 235. The first side cover transmission arrangement further comprises a driven first side cover transmission element 238. The driven first side cover transmission element 238 may be connected to the at least one motor 201 and the first elongated side cover transmission element 235 to cause movement of the first side cover 300.

[0119] In one embodiment, the transmission system comprises a second side cover transmission arrangement.

The driven second cover transmission element 248 may be connected to the at least one motor 201 and the second elongated side cover transmission element 245 to cause movement of the second side cover 400.

[0120] The first and / or second side cover elongated transmission element(s) 235, 245 may be provided as flexible elongated transmission element(s) 235, 245 such as chains, cables or wires or as rigid elongated transmission element(s) such as gear racks. The driven first and / or second side cover transmission element(s) 238, 248 may be provided as any type of rotatable transmission element suitable for engaging the elongated transmission element.

[0121] In the depicted example, the first and second side cover elongated transmission elements 235, 245 are provided as flexible elongated transmission elements. To improve the stability and robustness of the dock shelter operator system as well as the predictability of the operation of the first and / or second side cover 300, 400, support transmission elements for further supporting the elongated transmission elements may be utilized.

[0122] In one embodiment, the first side cover transmission arrangement comprises a first side cover support transmission element 234. The first side cover elongated transmission element 235 may extends from the driven first side cover transmission element 238 towards the first side cover 300 via said first side cover support transmission element 233. The first side cover elongated transmission element 235 may thus wrap around the first cover support transmission element 234.

[0123] In one embodiment, the second side cover transmission arrangement further comprises a second side cover support transmission element 244. The second side cover elongated transmission element 245 may extend from the driven second side cover transmission element 248 towards the second side cover 400 via said second side cover support transmission element 244. The second side cover elongated transmission element 245 may thus wrap around the second cover support transmission element 244.

[0124] Further referencing Figure 4, a portion of the first and second side cover elongated transmission elements may extend substantially horizontally and another portion may extend substantially vertically. Accordingly, the first side cover elongated transmission element 235 may comprise a first portion 236. The first portion 236 of the first side cover elongated transmission element 235 may extend between the driven first side cover transmission element 238 and the first side cover support transmission element 235. The first portion 236 may extend at least partially in a horizontal direction. Advantageously, the first portion 236 extends horizontally.

[0125] The first cover elongated transmission element 235 may comprise a second portion 237. The second portion 237 of said first side cover elongated transmission element 235 may extend towards the first side cover 300. The second portion 237 may extend at least partially in a vertical direction. Advantageously, the second portion 237 extends vertically. The second portion 237 may extend from the second side cover support transmission element 235.

[0126] In one embodiment, the second side cover elongated transmission element 245 may comprise a first portion 246. The first portion 246 of the second side cover elongated transmission element 245 may extend between the driven second side cover transmission element 248 and the second side cover support transmission element 245. The first portion 246 may extend at least partially in a horizontal direction. Advantageously, the first portion 246 extends horizontally.

[0127] The second cover elongated transmission element 245 may comprise a second portion 247. The second portion 247 of said second side cover elongated transmission element 245 may extend towards the second side cover 400. The second portion 247 may extend at least partially in a vertical direction. Advantageously, the second portion 247 extends vertically. The second portion 247 may extend from the second side cover support transmission element 245.

[0128] In the depicted example, the first and second side cover elongated transmission element(s) 235, 245 are provided as wires and the driven first and second side cover transmission element(s) are provided as driven pulleys.

[0129] Hence, the driven first side cover transmission element 238 may be provided as a driven first side cover pulley and the first elongated side cover transmission element 235 may be provided as a wire, and / or the driven second side cover transmission element 248 may be provided as a driven second side cover pulley and the second elongated side cover transmission element 245 may be provided as a wire.

[0130] Further, the first and / or second side cover transmission elements may be provided as pulleys. According to such an embodiment, the first side cover support transmission element 234 may be provided as a first side cover support pulley. Additionally or alternatively, the second side cover support transmission element 244 may be provided as a second side cover support pulley.

[0131] In the depicted example, the movement is caused by the driven transmission elements and the elongated transmission elements causing movements of arm arrangements further comprised in the transmission systems.

[0132] In one embodiment, the first side cover transmission arrangement comprises a first side arm arrangement 230. The first side arm arrangement 230 may be operable by means of the first elongated side cover transmission element 235. The first side arm arrangement 230 may comprise one or more pivotable arms 231, 232 connected to the first side cover 300. The one more pivotable arms 231, 232 may be arranged such that movement of the first side cover elongated transmission element 235 causes pivoting of said one or more pivotable arms 231, 232 and prompts operating of the first side cover 300 between the deployed state and stowed away state.

[0133] In one embodiment, the second side cover transmission arrangement comprises a second side arm arrangement 240. The second side arm arrangement 240 may be operable by means of the second elongated side cover transmission element 245. The second side arm arrangement 240 may comprise one or more pivotable arms 241, 242 connected to the second side cover 400. The one or more pivotable arms 241, 242 may be arranged such that movement of the second side cover elongated transmission element 245 causes pivoting of said one or more pivotable arms 241, 242 and prompts operating of the second side cover 400 between the deployed state and stowed away state.

[0134] In the depicted example, each of side arm arrangements comprises a pair of arms. Accordingly, the one or more pivotable arms 231, 232 of the first side arm arrangement 230 may comprise an upper pivotable arm 231 and a lower pivotable arm 232. Correspondingly, the one or more pivotable arms 241, 242 of the second side arm arrangement 240 may comprise an upper pivotable arm 241 and a lower pivotable arm 242. In the depicted example, the upper pivotable arm 231, 242 of the arm arrangements 230, 240 is caused to pivot while the lower pivotable arm 232, 242 of the arm arrangements 230, 240 forms a supporting arm. This improves the reliability and robustness of the operation of the covers. Furthermore, it allows for an improved reliability of an engaging element properly engaging the arm to operate the cover.

[0135] As aforementioned, the pivotable arm may be prompted by means of an engaging element engaging the arm forcing the arm to pivot. It may however be envisioned that the pivoting is caused by the elongated transmission element being connected to the at least one of the pivotable arms of the arm arrangements, thereby causing the arm to pivot.

[0136] In the depicted example, an engaging element is utilized for the pivoting of the arm(s).

[0137] Further referencing Figure 4, the first cover transmission arrangement may comprise a first side cover engaging member 233. The first side cover engaging member 233 may be suspended in the first side cover elongated transmission element 235. The first side cover engaging member 233 is arranged to engage the first side arm arrangement 230 to cause the one or more pivotable arms 231, 232 to pivot.

[0138] As further depicted in Figure 4, the second cover transmission arrangement may comprise a second side cover engaging member 243. The second side cover engaging member 243 may be suspended in the second side cover elongated transmission element 245. The second side cover engaging member 245 is arranged to engage the second side arm arrangement 240 to cause the one or more pivotable arms 241, 242 to pivot.

[0139] In the depicted embodiment, the cover engaging members 235, 245 are arranged to engage the upper arms of the arm arrangements 230, 240 to cause the one or more arms of the arm arrangements 230, 240 to pivot.

[0140] Upon rotation of the first side cover driven transmission element 238, in a first direction, the first side cover engaging member 233 will be pulled via the first side cover elongated transmission element 235 towards one of the arms 231, 232 of the first side arm arrangement 230 and engage said arm causing said arm to pivot thereby operating the first side cover 300. In the depicted example, the first side cover engaging member 233 is arranged underneath the upper arm 231 such that when the first side cover driven transmission element 238 is rotated in the first direction, the first side cover engaging member 233 is arranged to engage the upper arm 231 forcing the pivoting of the upper arm 231 and consequently also the pivoting of the lower arm 232 in a first pivoting direction, thereby forcing the second end portion of the first side cover 300 outwards towards the stowed away state. Upon rotation of the first side cover driven transmission element 238 in a second direction, opposite to the first, the first side cover engaging member 233 is arranged to be brought out of engagement with the upper arm 231 such that the weight of the upper arm 231 and lower arm 232 causes the said upper arm 231 and lower arm 232 to pivot in an opposite pivoting direction. Thereby, the second end portion of the first side cover 300 is forced inward towards the deployed state.

[0141] In the depicted example, the second side cover transmission arrangement may function similarly to the first side cover transmission arrangement. Hence, upon rotation of the second side cover driven transmission element 248, in a first direction, the second side cover engaging member 243 will be pulled via the second side cover elongated transmission element 245 towards one of the arms 241, 242 of the second side arm arrangement 240 and engage said arm causing said arm to pivot thereby operating the second side cover 400.

[0142] In the depicted example, the second cover engaging member 243 is arranged underneath the upper arm 241 such that when the second side cover driven transmission element 248 is rotated in the first direction, the second side cover engaging member 243 is arranged to engage the upper arm 241 forcing the pivoting of the upper arm 241 and consequently also the pivoting of the lower arm 242 in a first pivoting direction, thereby forcing the second end portion of the second side cover 400 outwards towards the stowed away state. Upon rotation of the second side cover driven transmission element 248 in a second direction, opposite to the first, the second side cover engaging member 243 is arranged to be brought out of engagement with the upper arm 241 such that the weight of the upper arm 241 and lower arm 242 causes the said upper arm 241 and lower arm 242 to pivot in an opposite pivoting direction. Thereby, the second end portion of the second side cover 400 is forced inwards towards the deployed state. In the depicted example, the dock shelter operator system 200 is configured to operate the first side cover 300 and / or the second side cover 400 in a horizontal as well as vertical direction between the stowed away state and the deployed state.

[0143] Accordingly, the pivoting of the one or more pivotable arms of the first and / or second side arm arrangement 230, 240 may cause a horizontal as well as vertical movement of the second end portion of first side cover 300 and the second side cover 400, respectively. Hence, the second end portion of the first side cover 300 may be pivotably connected to the one or more pivotable arms 231, 232 such that said second end portion follows the pivoting movement of said one or more pivotable arms 231, 232. Correspondingly, the second end portion of the second side cover 400 may be pivotably connected to the one or more pivotable arms 241, 242 such that said second end portion follows the pivoting movement of said one or more pivotable arms 241, 242

[0144] Upon pivoting of the one or more pivotable arms 231, 232 in the first pivoting direction, the second end portion of the first side cover 300 is forced to move upwards in a vertical direction and outwards in a horizontal direction towards the stowed away state. Upon pivoting of the one or more pivotable arms 231, 232 in the second pivoting direction, the second end portion of the first side cover 300 is forced to move downwards in a vertical direction and inwards in a horizontal direction towards the deployed state.

[0145] Upon pivoting of the one or more pivotable arms 241, 242 in the first pivoting direction, the second end portion of the second side cover 400 is forced to move upwards in a vertical direction and outwards in a horizontal direction towards the stowed away state. Upon pivoting of the one or more pivotable arms 241, 242 in the second pivoting direction, the second end portion of the second side cover 400 is forced to move downwards in a vertical direction and inwards in a horizontal direction towards the deployed state.

[0146] To enable operation of a potential upper cover 500, the transmission system 210 may further comprise an upper cover transmission arrangement. The upper cover transmission arrangement is schematically depicted in Figure 4.

[0147] The upper cover transmission arrangement may comprise one or more elongated upper cover transmission elements 255, 265. The upper cover transmission arrangement may further comprise one or more driven upper cover transmission element 258, 268. The one or more driven upper cover transmission element 258, 268 may be connected to the at least one motor 201. The one or more driven upper cover transmission element 258, 268 may be further be connected to the one or more elongated upper cover transmission element 255, 265 to cause movement of the upper cover 500.

[0148] In the depicted example, the upper cover transmission arrangement comprises a first elongated upper cover transmission element 255. The first elongated upper cover transmission element 255 may be connected to a first driven upper cover transmission element 258. The first elongated upper cover transmission element 255 may be arranged at a first side of the upper cover 500.

[0149] In the depicted example, the upper cover transmission arrangement comprises a second elongated upper cover transmission element 265. The second elongated upper cover transmission element 265 may be connected to a second driven upper cover transmission element 268. The second elongated upper cover transmission element 265 may be arranged at a second side of the upper cover 500.

[0150] The second side of the upper cover 500 may be opposite to the first side. The first and second side may refer to the vertical sides of the upper cover 500.

[0151] The one or more elongated upper cover transmission elements 255, 265 may be provided as flexible elongated transmission element(s) 255, 265 such as chains, cables or wires or as rigid elongated transmission element(s) such as gear racks. The one or more driven upper cover transmission element 255, 265 may be provided as any type of rotatable transmission element suitable for engaging the elongated transmission element.

[0152] In the depicted example, the one or more elongated upper cover transmission element 255, 256, e.g. the first and second side elongated upper cover transmission elements 255, 265, are provided as flexible elongated transmission elements. To improve the stability and robustness of the dock shelter operator system as well as the predictability of the operation of the upper cover 500, support transmission elements for further supporting the elongated transmission elements may be utilized.

[0153] Accordingly, the upper cover transmission arrangement may comprise one or more upper cover support transmission element 254, 264. The elongated upper cover transmission element 255, 265 may extend from the driven upper cover transmission element 258, 268 towards the upper cover 500 via the upper cover support transmission element 254, 264.

[0154] In one embodiment, the one or more elongated upper cover transmission element 255, 265 may comprise a first portion 256, 266. The first portion 256, 266 of the elongated upper cover transmission element 255, 265 may extend between the driven upper cover transmission element 258, 268 and the upper cover support transmission element 255, 265. The first portion 256, 266 may extend at least partially in a horizontal direction. Advantageously, the first portion 256, 266 may extend horizontally.

[0155] In one embodiment, the one or more elongated upper cover transmission element 255, 265 may comprise a second portion 257, 267. The second portion 257, 267 of the elongated upper cover transmission element 255, 265 may extend towards the upper cover 500. The second portion 257, 267 may extend at least partially in a vertical direction. Advantageously, the second portion 257, 267 may extend vertically.

[0156] In the depicted example, the one or more upper cover support transmission element 255, 265 comprises a first upper cover support transmission element 255 and a second upper cover support transmission element 265. The first elongated upper cover transmission element 255 may extend from the first driven upper cover transmission element 258 towards the upper cover 500 via the first upper cover support transmission element 255. The second elongated upper cover transmission element 265 may extend from the second driven upper cover transmission element 268 towards the upper cover 500 via the second upper cover support transmission element 265.

[0157] In one embodiment, the one or more driven upper cover transmission element 258, 268 is provided as a driven upper cover pulley and the one or more elongated upper cover transmission element 255, 265 is provided as a wire.

[0158] In the depicted example, the first and second elongated upper cover transmission element 255, 265 are provided as wires and the driven first and second upper cover transmission elements 258, 268 are provided as driven pulleys.

[0159] Further, the one or more upper cover support transmission element 254, 264, e.g. the first upper cover support transmission element 254 and the second upper cover support transmission element 264, may be provided as an upper cover support pulley, e.g. a first and second upper cover support pulley.

[0160] As shown in Figure 4, the transmission system 210 may comprise a first rotatable support unit 281. The first upper cover support transmission element 256 and the first side cover support transmission element 234 may be arranged on the first rotatable support unit 281. The first rotatable support unit 281 may form a shaft, whereby the first upper cover support transmission element 256 and the first side cover support transmission element 234 are arranged on said shaft. The first rotatable support unit 281 may be arranged above the upper cover 500 at a horizontal distance from the at least one motor 201 and / or the first driven upper cover transmission element 258 and the driven first side cover transmission element 238.

[0161] The transmission system 210 may further comprise a second rotatable support unit 282. The second upper cover support transmission element 264 and the second side cover support transmission element 244 may be arranged on the second rotatable support unit 282. The second rotatable support unit 282 may form a shaft, whereby the second upper cover support transmission element 266 and the second side cover support transmission element 244 are arranged on said shaft. The second rotatable support unit 282 may be arranged above the upper cover 500 at a horizontal distance from the at least one motor 201 and / or the second driven upper cover transmission element 268 and the driven second side cover transmission element 248. The second rotatable support unit 282 may be arranged at a horizontal distance from said at least one motor 201 and / or the second driven upper cover transmission element 268 and the driven second side cover transmission element 248 in an opposite horizontal direction relative the first rotatable support unit 281.

[0162] The rotatable support unit(s) allows for a transmission system which is more space efficient and allows for a more synchronized operation of the covers.

[0163] It may envisioned that the one or more upper cover elongated upper cover transmission member 253, 263 is directly connected to and attached to the upper cover 500 to cause operation of the upper cover 500. However, in the depicted example, an engaging member is utilized to engage the upper cover 500 and cause the operation of said upper cover 500. Referencing Figure 4, the upper cover transmission arrangement comprises one or more upper cover engaging member 253, 263. The upper cover engaging member 253, 263 may be suspended in one of the one or more elongated upper cover transmission element 257, 267. The one or more upper cover engaging member 253, 263 may be arranged to engage the upper cover 500 to cause operation of the upper cover 500.

[0164] Rotation of the one or more driven upper cover transmission element 258, 268 may cause movement, e.g. vertical movement, of the one or more upper cover engaging member 253, 263 due to the resulting movement of the one or more elongated upper cover transmission elements 255, 265. Upon the one or more upper cover engaging members 253, 263 engaging the upper cover 500, the said one or more upper cover engaging members 253, 263 is arranged such that the upper cover 500 is dragged between the stowed away state and the deployed state.

[0165] In the depicted example, upper cover transmission arrangement is arranged such that rotation of the one or more driven upper cover transmission element 258, 268 in a first rotation direction causes vertical movement of the one or more elongated upper cover transmission elements 255, 265 and the one or more upper cover engaging member 253, 263 to move upwards towards the upper cover 500 and engage said upper cover 500. Upon further upward movement the upper cover 500 will be pushed upwards towards the stowed away state by means of the one or more upper cover engaging member 255, 265. Accordingly, the second end portion is moved upwards by means of the upper cover engaging members 255, 265 pushing on the upper cover 500, thereby operating the upper cover 500 towards the stowed away state.

[0166] The upper cover transmission arrangement may be further arranged such that rotation of the one or more driven upper cover transmission element 258, 268 in a second rotation direction opposite to the first causes vertical movement of the one or more elongated upper cover transmission elements 255, 265 and the one or more upper cover engaging member 253, 265 to move downwards, allowing the weight of the upper cover 500 to release the upper cover 500 towards the deployed state. Accordingly, the second end portion is moved downwards by means of the upper cover engaging members 255, 265 moving downwards, thereby operating the upper cover 500 towards the stowed away state. In the depicted example, a first upper cover engaging member 253 is suspended in the first elongated upper cover transmission element 255 and arranged to engage the upper cover 500 to cause operation of the upper cover 500. Correspondingly, a second upper cover engaging member 263 is suspended in the second elongated upper cover transmission element 265 and arranged to engage the upper cover 500 to cause operation of the upper cover 500.

[0167] Figure 5a-b depicts aspects of the dock shelter operator system. In the depicted example, the driven transmission elements described with reference to Figure 4 and a motor is comprised in a drive unit 203 of the dock shelter operator system. The drive unit comprises the at least one motor 201. In the depicted example, the drive unit 203 comprises a single motor 201.

[0168] The drive unit 203 may comprise the one or more driven upper cover transmission element 258, 268 and / or the driven first side cover transmission element 238 and / or the driven second side cover transmission element 248. In the depicted example, the drive unit 203 comprises the first driven upper cover transmission element 258, the second driven upper cover transmission element 268, the driven first side cover transmission element 238 and the driven second side cover transmission element 248.

[0169] The drive unit 203 may comprise the one or more driven upper cover transmission element 258, 268 and / or the driven first side cover transmission element 238 and / or the driven second side cover transmission element 248 may be coaxially arranged on a shaft 202 connected to the motor 201. The shaft 202 is driven by means of said motor 201. The shaft 202 may thus be an output shaft 202 of the motor 201.

[0170] In the depicted embodiment, the one or more driven upper cover transmission element 258, 268 and the driven first and second side cover transmission element 238, 248 are coaxially arranged on the shaft 202 connected to the motor 201.

[0171] The one or more driven upper cover transmission element 258, 268 and / or the driven first side cover transmission element 238 and / or the driven second side cover transmission element 248 may be provided as pulleys arranged the shaft 202.

[0172] Advantageously, the driven upper cover transmission element 258, 268 have a larger diameter than the driven first and second side cover transmission element 238, 248. This is particularly advantageous due to the weight of upper cover 500 at times during operation will be carried by the one or more upper cover elongated transmission elements, whereby the driven upper cover transmission elements 258, 268 may be dimensioned to withstand a higher load compared to the driven first and second side cover transmission element 238, 248.

[0173] Figure 6a-d depicts the upper cover 500 in further detail. 6a depicts a section of the upper cover 500 at the first vertical side of the upper cover 500 while 6b-c depicts a bottom section of the upper cover at the second vertical side of the upper cover 500.

[0174] Referencing Figure 6a-d, the docking shelter system 100 may comprise one or more guide elements 259. The one or more guide elements 259 may extend at least partially in a vertical direction, preferable vertically. The one or more guide elements 259 may be arranged to provide a guide for the upper cover 500 upon operation between the deployed state and the stowed away state. Thereby a more predictable and stable operation of the upper cover 500 may be provided.

[0175] The one or more guide elements 259 may be in engagement with the upper cover 500 or may extend parallel to the upper cover 500 thus only engaging the upper cover 500 in cases of the upper cover 500 tilting inward or outward.

[0176] Referencing Figure 6a-d, the one or more guide elements 259 may be arranged to extend through a set of holes 545 provided in the upper cover 500. The one or more guide elements 259 may be arranged to extend through the set of holes 545 such that the one or more guide element 259 is in engagement with the upper cover 500 upon operation of the upper cover 500 between the deployed state and the stowed away state.

[0177] The one or more guide element 259 may thus engage the sheet element 540 to provide a guide for the folding and unfolding of the interconnected sections 550 of the sheet element 540 upon operation of the upper cover 500 between the deployed state and the stowed away state.

[0178] The one or more guide elements 259 comprises a first and second guide element 259A-B arranged at a first vertical side and a second vertical side of the upper cover 500, respectively. The second vertical side being opposite to the first vertical side.

[0179] In the depicted example, the one or more guide elements 259 are provided as a guide wire. The guide wire may be suspended in a vertical direction. As depicted in Figure 6a-d, the upper cover 500 may comprise a first set of holes 545 extending along and proximal to a first vertically extending edge of the upper cover 500 and a second set of holes 545 extending along and proximal to a second vertically extending edge of the upper cover 500. The first guide element 259A may extend through the first set of holes and the second guide element 259B may extend through the second set of holes.

[0180] Figure 6b-d depicts the bottom portion, e.g. the second end portion 522, of the upper cover 500 in further detail. As previously described, the upper cover 500 may comprise the profile 580. The profile 580 may comprise the rigid profile portion 581. The rigid profile portion 581 is attached to the sheet element 540.

[0181] In the depicted example, the profile 580 is in a rigid material. Accordingly, the rigid profile portion 581 may be adapted to engage the vehicle trailer 2. In one embodiment, the rigid profile portion 581 may be arranged to engage the vehicle trailer 2 in the deployed state. This may be particularly advantageous in the case of an upper cover as the vehicle trailer 2 typically provides an even horizontal surface to engage for the upper cover. Hence, adding non-rigid material to improve the sealing properties of the cover is not required, making the cover more cost-efficient and durable.

[0182] Figure 6b-d further shows the extension of the one or more elongated upper cover transmission elements 255, 265, e.g. the first elongated upper cover transmission element 255 and the second elongated upper cover transmission element 265. As depicted, the profile 580 may comprise a vertically extending through-hole adapted to receive the elongated upper cover transmission element 255, 265. The profile 580 may comprise a first vertically extending through-hole adapted to receive the first elongated upper cover transmission element 255 and a second vertically extending through-hole adapted to receive the second elongated upper cover transmission element 265.

[0183] Figure 7 depicts the upper cover 500 from a side view. In the depicted example, the upper cover 500 comprises a single sheet element 540. Further, the upper cover 500 comprise a plurality of horizontally extending stiffening cross-members 560.

[0184] The vertically extending guide element 259 extends vertically through the interconnected sections 550 of the upper cover 500. Each interconnected section 550 may be provided with a hole 545 such that the sheet element 540 of the upper cover 500 extends in a zig-zag pattern intersecting with the vertically extending guide element 259.

[0185] As depicted in Figure 7, the one or more vertically extending guide members 259 may be connected to the shelter support structure 50 by means of a hook connection 5900. It may however be envisioned that the one or more vertically extending guide members 259 may be attached to a neighboring wall and / or with any type of other conventional mounting structure.

[0186] Figure 8a depicts the first side cover 300. Figure 8 depicts the first side cover 300, however the features described with reference to the first side cover 300 may analogously apply for the second side cover 400.

[0187] The one or more pivotable arms 231, 232 of the first side arm arrangement 230 may be pivotably connected to the second end portion 322 of the first side cover 300. The one or more pivotable arms 231, 232 may be pivotably connected to the profile 380 of the first side cover 300. Accordingly, the upper pivotable arm 231 and the lower pivotable arm 232 may be pivotably connected to the second end portion 322 of the first side cover 300 and preferably the profile 380 of the first side cover 300.

[0188] Analogously, the one or more pivotable arms 241, 242 of the second side arm arrangement 240 may be pivotably connected to the second end portion 422 of the second side cover 300. The one or more pivotable arms 241, 242 may be pivotably connected to the profile 480 of the second side cover 400. Accordingly, the upper pivotable arm 241 and the lower pivotable arm 242 may be pivotably connected to the second end portion 422 of the second side cover 400 and preferably the profile 480 of the second side cover 400.

[0189] As depicted, a first end portion 2331 of the one or more pivotable arm 231, 232 of the first side arm arrangement 230 may be pivotably connected to the first side cover 300. A second end portion 2332 of the one or more pivotable arm 231, 231 may be pivotably mounted to a pivot point.

[0190] Further referencing Figure 8a, a first end portion 2331 of the one or more pivotable arm 231, 232 of the first side arm arrangement 230 is pivotably connected to the first side cover 300. A second end portion 2332 may be pivotably mounted to a pivot point. The first end portion 2331 may be opposite to the second end portion 2332. The first end portion 2331 may be pivotable connected to the profile 380 of the first side cover 300.

[0191] Correspondingly, a first end portion 2331 of the one or more pivotable arm 231, 232 of the second side arm arrangement 240 may be pivotably connected to the second side cover 400. A second end portion 2332 may be pivotably mounted to a pivot point. The first end portion 2331 may be opposite to the second end portion 2332. The first end portion 2331 may be pivotable connected to the profile 380 of the second side cover 400. The second end portion 2332 may be mounted to a support profile 5300 of the shelter support structure 50. The support profile 5300 may be mounted to the support frame of the shelter support structure 50. The support profile 5300 may extend in a vertical direction.

[0192] Advantageously, the first end portion 2331 and the second end portion 2332 may be pivotable about a horizontal pivot axis extending substantially orthogonally to the horizontal extension of the first and / or second side cover 300, 400 in the deployed state.

[0193] In one embodiment, the one or more cover 300, 400, 500 may be spring-biased towards the stowed away state by means of one or more biasing springs 311. The one or more biasing springs 311 may be arranged to bias the first end portion of the one or more cover 300, 400, 500 relative the second end portion of said one or more cover 300, 400, 500.

[0194] Advantageously, the first side cover 300 and / or the second side cover 400 may be spring-biased towards the stowed away state by means of a plurality of biasing springs 311 distributed along the height of the first side cover 300 and / or the second side cover, respectively.

[0195] Figure 8b depicts the biasing spring 311 in further detail. The plurality of biasing springs 311 may be arranged to provide a biasing force between the first side cover 300 and the shelter support structure 50 and / or to prove a biasing force between the second side cover 400 and the shelter support structure 50. Hence, a first plurality of biasing springs 311 may be arranged to provide a biasing force between the first side cover 300 and the shelter support structure 50, e.g. the first vertical frame member 52 of the shelter support structure 50. Correspondingly, a second plurality of biasing springs 311 may be arranged to provide a biasing force between the second side cover 400 and the shelter support structure 50, e.g. the second vertical frame member 53 of the shelter support structure 50.

[0196] The biasing springs 311 may be arranged such that a tensioning force is exerted on the side cover 300, 400 towards the stowed away state, thereby there is tension in said side cover 300, 400 in the deployed state. This may cause an improved sealing and improved manoeuvrability of the side covers.

[0197] As depicted in Figure 8b, the biasing springs 311 may have a first end connected to the first or second side cover 300, 400 and a second end connected to the shelter support structure 50, e.g. the first or second vertical frame member 52, 53.

[0198] Figure 9a-b depicts an upper pivotable arm 231 of the first side arm arrangement 230. As depicted, the upper pivotable arm 231 may comprise an aperture 2333. The aperture 2333 may be arranged to receive the first elongated side cover transmission element 235. The first elongated side cover transmission element 235 may thus extend through said aperture 2333. Upon the first elongated side cover transmission element 235 raising the first side cover engaging member 233, the first side cover engaging member 233 is brought into engagement with the upper pivotable arm 231 thereby pushing the first end portion 2331 of the upper pivotable arm 231 upwards in turn causing operation of the first side cover 300 towards the stowed away position. As depicted, the aperture 2333 may be arranged adjacent to the first end portion 2331 of the pivotable arm 230.

[0199] In one embodiment, an upper pivotable arm 231 of the second side arm arrangement 240 may comprise an aperture 2333 engaging with the second elongated side cover transmission element 245 and the second side cover engaging member 243 analogously to the above.

[0200] Figure 10-11 depicts aspects of the first side cover 300. Notably, the aspects may also be applied analogously to the second side cover 400.

[0201] As depicted the one or more cover 300, 400, 500 may comprise the profile. In the depicted example, the profile 380 may comprise a resilient profile portion 382. The resilient profile portion 382 may be mounted to the rigid profile portion 381. The resilient profile portion 382 may be adapted to engage the vehicle trailer 2. The resilient profile portion 382 may be in a flexible material such as an elastomeric material. The elastomeric material may be rubber. In other words, the resilient profile portion 382 may be in an elastomeric material such as rubber.

[0202] The resilient profile portion 382 allows for a tighter sealing between the cover and the vehicle trailer. Furthermore, the resilient properties of the resilient profile portion 382 allows for the cover to more accurately engage the vehicle trailer even in cases where the vehicle is parked in an angle relative the docking shelter system due to the material of the resilient profile portion 382 being able to follow the shape of the vehicle trailer. In the depicted example, the resilient profile portion 382 is clamped to the rigid profile portion 381 by means of a press-fit. It may however be envisioned that the resilient profile portion 382 is mounted to the rigid profile portion 381 by means of one or more fastening elements.

[0203] The resilient profile portion 382 may comprise a chamber. The chamber may formed by a longitudinal aperture 383 extending along the profile 380. The chamber may further improve the ability of the resilient profile portion 382 to deform to engage the vehicle trailer due the adapted cross-section due to chamber altering the stiffness of the resilient profile portion 382.

[0204] In one embodiment, the resilient profile portion 382 may comprise one or more sealing flaps 384. The one or more sealing flaps 384 may be adapted come into contact with the vehicle trailer 2.

[0205] Preferably, the first side cover 300 comprises the resilient profile portion 382. Additionally or alternatively, the second side cover 400 may comprise resilient profile portion 382. The resilient profile portion being implemented for the profile of a side cover is particularly advantageous due to the side covers often having to accommodate to the trail vehicle standing at an angle relative to the dock shelter.

[0206] Further referencing Figure 10-11, at least one of one or more covers 300, 400, 500 may comprise an inner sheet element 341 and an outer sheet element 342. The inner sheet element 341 and the outer sheet element 342 may extend parallel to and at a distance from each other. The inner and outer sheet element may improve the sealing properties of said cover.

[0207] In one embodiment, each of the inner sheet element 341 and the outer sheet element 342 comprise interconnected sections 350. To improve the structural integrity of the cover, the inner sheet element 341 and the outer sheet element 342 may each be mounted to the profile 380.

[0208] Preferably, the first side cover 300 and / or the second side cover 400 may comprise the inner and outer sheet element. Accordingly, the first side arm arrangement 230 and / or the first elongated side cover transmission element 235 may extend between an inner and outer sheet element of the first side cover 300. Correspondingly, the second side arm arrangement 240 and / or the second elongated side cover transmission element 245 may extend between an inner and outer sheet element of the second side cover 400. Thereby, the moving arms and elongated transmission elements may covered from both sides, improving the safety of the dock shelter operator system.

[0209] An alternative embodiment of a side arm arrangement is depicted in Figure 12. The alternative embodiment may advantageously share all of the features of the side arm arrangements, i.e. the first and second side arm arrangement, previously described apart from the arranging of the second end portion of the one or more pivotable arm and the addition of a support arm. The side arm arrangement depicted in Figure 12 may allow for a more stable and robust side cover even during operation.

[0210] Referencing Figure 12, a first side arm arrangement is depicted. It may however be envisioned that both the first and second side arm arrangement or only the second side arm arrangement may comprise a slidable arm and a support arm as depicted in Figure 12.

[0211] The second end portion 2332 of the one or more pivotable arms 231, 232 of the first side arm arrangement 230 may be slidably mounted to a guide rail 2339. The guide rail 2339 may extend substantially orthogonally to the first side cover 300. The side arm arrangement 230 may further comprise a support arm 2338. The support arm 2338 may have a first end portion pivotably mounted to a support pivot point. The support arm 2338 may have a second end portion pivotably mounted to an intermediate portion of said one of the one or more pivotable arms 231, 232.

[0212] The support arm 2338 may be adapted to pivot about a horizontal axis extending substantially orthogonally to the first side cover 300 when the first side cover 300 is in the deployed state. The second end portion 2332 of the pivotable arm 231, 232 may be pivotably mounted to a sliding member arranged in sliding engagement with the guide rail 2339. Upon the first side cover engaging member engaging the pivotable arm 231, 232, the pivotable arm 231, 232 will pivot causing the second end portion 2332 to travel along the guide rail 2339 urging the operation of the first side cover 300. The guide rail 2339 may be provided in the support profile 5300.

[0213] In the depicted example, an upper support arm 2338 is pivotably mounted to an intermediate portion of the upper pivotable arm 231. The second end portion 2332 of the upper pivotable arm 231 is slidably mounted in an upper guide rail 2339. Further referencing the depicted example, a lower support arm 2338 is pivotably mounted to an intermediate portion of the lower pivotable arm 232. The second end portion 2332 of the lower pivotable arm 232 is slidably mounted in a lower guide rail 2339.

[0214] The above may apply analogously to the second side arm arrangement 240. Accordingly, the second end portion 2332 of at least one of the one or more pivotable arms 231, 232 of the one or more pivotable arms 241, 242 of the second side arm arrangement 240 may slidably mounted to a guide rail 2339. The guide rail 2339 may extend substantially orthogonally to the second side cover 400. The second side arm arrangement 240 may further comprise a support arm 2338. The support arm 2338 may have a first end portion pivotably mounted to a support pivot point. The support arm 2338 may have a second end portion pivotably mounted to an intermediate portion of said at least one of the one or more pivotable arms 241, 242.

[0215] Preferably, the second side arm arrangement 240 comprises an upper pivotable arm 241 and a lower pivotable arm 242. Accordingly, an upper support arm 2338 may be pivotably mounted to an intermediate portion of the upper pivotable arm 241. The second end portion 2332 of the upper pivotable arm 241 may be slidably mounted in an upper guide rail 2339. Correspondingly, a lower support arm 2338 may be pivotably mounted to an intermediate portion of the lower pivotable arm 242. The second end portion 2332 of the lower pivotable arm 242 may be slidably mounted in a lower guide rail 2339.

[0216] Due to the guide rail 2339, the arm arranged described with reference to Figure 12 may operate the first or second side cover in a horizontal direction between the deployed state and the stowed away state. Accordingly, the second end portion of the first or second side cover may move horizontally as the first or second side cover is operated between the stowed away state and the deployed state.

[0217] Accordingly, in the depicted example, the dock shelter operator system 200 is configured to operate the first side cover 300 and / or the second side cover 400 in a horizontal direction between the stowed away state and the deployed state. Advantageously, the dock shelter operator system 200 is configured to operate the first side cover 300 and / or the second side cover 400 solely in a horizontal direction between the stowed away state and the deployed state

[0218] Referencing Figure 12, the pivoting of the one or more pivotable arms of the first and / or second side arm arrangement 230 may cause a horizontal movement of the second end portion of first side cover 300 and the second side cover 400, respectively. Hence, the second end portion of the first side cover 300 may be pivotably connected to the first end portion 2331 of one or more pivotable arms 231, 232 and the second end portion 2332 may be slidably mounted in the guide rail 2332 such that upward movement of the first end portion 2331 causes horizontal movement of the second end portion of the first side cover 300. Correspondingly, the second end portion of the second side cover 400 may be pivotably connected to the first end portion 2331 of one or more pivotable arms of the second side arm arrangement and the second end portion 2332 of one or more pivotable arms of the second side arm arrangement may be slidably mounted in the guide rail 2332 such that upward movement movement of the first end portion 2331 causes horizontal movement of the second end portion of the second side cover 300.

[0219] Upon pivoting of the one or more pivotable arms 231, 232 in a first pivoting direction, the second end portion of the first side cover 300 is forced to move inwards in a horizontal direction towards the deployed state. Upon pivoting of the one or more pivotable arms 231, 232 in a second pivoting direction opposite to the first, the second end portion of the first side cover 300 is forced to move outwards in a horizontal direction towards the stowed away state.

[0220] Upon pivoting of the one or more pivotable arms of the second side arm arrangement in a first pivoting direction, the second end portion of the second side cover 400 is forced to move inwards in a horizontal direction towards the deployed state. Upon pivoting of the one or more pivotable arms of the second side arm arrangement in a second pivoting direction opposite to the first, the second end portion of the second side cover 400 is forced to move outwards in a horizontal direction towards the stowed away state.

[0221] It is noted that although the operation of the side covers is described with reference to particular direction, the resulting movement of the second end portion of the side covers in response to the pivoting movement of the pivotable arms may vary depending on the initial positioning of the pivotable arms.
