Description

Technical Field

[0001] The invention relates to a fastening device, a gas fuel storage assembly and a vehicle. The invention also relates to a method for assembling a gas fuel storage assembly. Background Art

[0002] The container may be connected to the structure using a fastening arrangement using a strap arrangement connected to the structure.One or more straps of the strap arrangement may extend at least partially around the container.

[0003] One type of container connected to a structure in this manner may be a pressure vessel. For example, the pressure vessel may be a pressure vessel for compressed gas, and the structure may be the chassis of a vehicle, such as a gas powered vehicle.

[0004] The tension in the one or more straps of the strap arrangement around at least a portion of the container ensures that the container is securely held by the one or more straps and is therefore securely attached to the structure by the fastening arrangement. The clamping force provided by the fastening arrangement causes tension in the one or more straps.

[0005] It can be difficult to provide a suitable clamping force in a fastening arrangement that includes one or more straps that extend at least partially around a container.

[0006] A common fastening device provides a rigid fixation. With this fastening device, the initial clamping force can be controlled. However, in the case of a pressure vessel, the diameter of the pressure vessel can vary, i.e. the diameter increases as it is pressurized and decreases when the pressure is reduced again. As a result, the clamping force and the tension in one or more bands also increase or decrease. When the elasticity of at least one band is low, the clamping force increases sharply and imposes considerable additional stress on the fastening device.

[0007] This sharp increase in clamping force can be avoided in different kinds of known fastening devices. The fastening device comprises a spring and expands as the diameter of the container increases. Thus, as the diameter of the container increases, the clamping force and the tension in the band or bands increase only within a limited range of the initial force / tension.

[0008] For example, WO 2018 / 030931 A1 discloses an example of a fuel tank attachment structure in a motor vehicle having at least one expandable and retractable fuel tank mounted thereon for storing compressed gas. The fastening device comprises at least one bracket fixed to the vehicle chassis for supporting at least one fuel tank and at least one tensioning belt surrounding the fuel tank. At least one tensioning device acts between a first end and a second end of the tensioning belt, whereby a spring load of the tensioning device applies a retaining force of the tensioning belt to the gas tank, regardless of whether the gas tank is expanded. At least one tensioning device comprises two fork-shaped fastening elements, wherein a spring device is arranged between the handles of the fork-shaped fastening elements. The assembly and installation of the fuel tank attachment structure, in particular the installation of the fork-shaped fastening elements, may be cumbersome and expensive. Summary of the invention

[0009] The present invention aims to provide an alternative fastening device to the fastening device disclosed in WO 2018 / 030931 A1. It would be advantageous to achieve a fastening device having a structure that is less complex than the structure disclosed in WO 2018 / 030931 A1. In particular, it is desirable to be able to enable a belt to be tensioned around at least a portion of a container in a fastening device that is easy to assemble. In order to better address one or more of these problems, a fastening device, a gas fuel storage assembly, a vehicle and / or a method having the features defined in one or more of the independent claims is provided. It should be understood that all various examples of the fastening device are also applicable to the gas fuel storage assembly, vehicle and / or method as disclosed herein, and vice versa.

[0010] According to one aspect, a fastening device for fastening a first container and a second container to a structure of a vehicle is provided. The fastening device comprises: an elongated member, the elongated member being at least partially provided with an external engagement member; a first abutment, the first abutment being arranged concentrically with the elongated member; a displaceable member, the displaceable member being connectable to a first band member configured to extend at least partially around the first container and a second band member configured to extend at least partially around the second container; a guide device, the guide device comprising a second abutment; a perforated member, the perforated member being at least partially provided with an internal engagement member; and an elastically compressible member, the elastically compressible member being positioned between the first abutment and the displaceable member or between the second abutment and the perforated member. The elongated member extends along an axis, and the displaceable member, the guide device, the elastically compressible member and the perforated member are aligned along the axis. The elongated member extends through the displaceable member and at least partially through the guide device for engagement between the external engagement member of the elongated member and the internal engagement member of the perforated member for compressing the elastically compressible member.

[0011] Since the fastening device includes a slender member, a displaceable member connectable to the first and second band members, a guiding device, a perforated member, and an elastically compressible member, and since the slender member extends through the displaceable member and at least partially through the guiding device for engagement between an outer engaging member of the slender member and an inner engaging member of the perforated member for compressing the elastically compressible member, the displaceable member is biased to tension the first and second band members via the elastically compressible member.

[0012] Thus, the fastening arrangement is configured to facilitate tensioning of the first and second band members at least partially around the first and second containers, respectively, via compression of the resiliently compressible member through engagement between the outer engagement member of the elongated member and the inner engagement member of the apertured member.

[0013] Furthermore, the elastically compressible member not only provides tension in the first band member and the second band member, but also, due to the compressible nature of the elastically compressible member, ensures that limited further strain is applied to the first band member and the second band member in the event of expansion of the first container and the second container (which may occur if the first container and the second container are pressure vessels).

[0014] The present fastening arrangement provides for easy tensioning of the first and second strap members, as only the elongate member has to engage with the apertured member.This provides a cost-effective way of fastening two containers to the structure of a vehicle.

[0015] More specifically, the fastening means is used to fasten the first container and the second container to a structure of a vehicle.The structure of the vehicle may be a structure forming part of a chassis of the vehicle or a structure configured to be attached to a chassis of a vehicle.

[0016] The first and second strap members extend at least partially around respective ones of the first and second containers. In addition to being connectable to the displaceable member at respective first ends of the first and second strap members, opposite second ends of the first and second strap members are fixed relative to the vehicle, for example by being connected to a structure of the vehicle.

[0017] As mentioned above, in the fastening device, an engagement between an outer engagement member for the elongated member and an inner engagement member of the foraminous member is provided. Here, for simplicity, it may be referred to alternatively as an engagement between the elongated member and the foraminous member or an engagement of the elongated member with the foraminous member. Thus, such engagement or engagement is provided by an outer engagement member of the elongated member and an inner engagement member of the foraminous member.

[0018] The elongated member is arranged such that the resiliently compressible member is compressed or compressible between the first abutment and the displaceable member or between the second abutment and the perforated member when engaged with the perforated member. Thus, when the resiliently compressible member is compressed, the first and second band members are tensioned and the first and second containers are securely fastened to the structure of the vehicle.

[0019] The first container and the second container may be pressure vessels. The pressure vessel may be made of metal (e.g., steel) or composite material (e.g., carbon fiber reinforced material). In the latter case, the expansion of the pressure vessel under pressure may be smaller than if the vessel is made of metal (e.g., steel).

[0020] At least the first container and the second container may have a circular shape, such as a substantially cylindrical shape. At least the first container and the second container may be configured to store gas. Thus, the first container may be a first gas storage tank and the second container may be a second gas storage tank. At least the first container and the second container may be configured to store CNG (compressed natural gas).

[0021] However, the term "container" is to be interpreted broadly and may include cans, vessels, housings for vehicle components such as batteries, tool boxes, and the like.

[0022] The displaceable member forms a link between the fastening device and the first and second belt members. To fasten the first and second containers to the structure of the vehicle, the displaceable member is displaced along the axis when the elongated member engages with the apertured member. Thus, the first and second belt members are tightened at least partially around the first and second containers, respectively.

[0023] Engagement of the elongated member with the apertured member positions the displaceable member relative to the guide arrangement such that the first and second band members are tightened around at least a portion of the first and second containers.

[0024] During installation of the fastening device, engagement of the elongated member with the apertured member causes the displaceable member to displace toward the apertured member.Such displacement of the displaceable member causes the first and second band members to provide a clamping force around the respective first and second containers.

[0025] As described above, the first and second strap members are configured to extend at least partially around the first and second containers, respectively. Thus, the lengths of the first and second strap members are determined by the associated containers and, optionally, also by the associated structures to which the containers will be connected by the fastening means. In general, larger containers may require longer strap members than smaller containers.

[0026] The tension in the first and second strap members ensures that the first and second containers are securely connected to the structure of the vehicle.When the elongated member is engaged with the apertured member, a clamping force causing tension in the first and second strap members is provided by the resiliently compressible member.

[0027] The elongated member may be a screw or a bolt or any other suitable elongated object provided with an external engagement member and strong enough to withstand the forces caused by the elastically compressible member and the tension in the first and second strap members during use of the fastening device. For example, the elongated member may be made of a metal such as steel.

[0028] The external engagement member of the elongate member may be, for example, a thread or a protrusion forming part of a ratchet mechanism or a snap fit mechanism.

[0029] The apertured member may be, for example, a nut or a tube portion adapted to at least partially receive a portion of the elongate member therethrough.

[0030] The internal engagement member of the apertured member may be, for example, a thread or a projection forming a part of a ratchet mechanism or a snap-fit ​​mechanism. That is, the internal engagement member is at least partially arranged inside the aperture of the apertured member.

[0031] Thus, engagement between the outer engagement member and the inner engagement member may be achieved by tightening the outer and inner threads or by pushing the elongate member into the apertured member for engagement of a ratchet mechanism or a snap fit mechanism.

[0032] In the present context the term abutment relates to that portion of a member, element etc. which directly receives the thrust or pressure force caused by the compressed resiliently compressible member and the tension in the first and second strap members during use of the fastening device.

[0033] The first abutment may form part of the elongated member or part of a separate element, such as a sleeve arranged around the elongated member.The second abutment may form an integral part of the guiding means or be formed by an element comprised in the guiding means.

[0034] The guide device is configured to be fixed to the structure of the vehicle. Thus, the guide device forms an anchor point or attachment point for the fastening device to the structure of the vehicle.

[0035] For example, the guide device may be screwed or welded to the structure of the vehicle.

[0036] As mentioned above, the elongate member extends through the displaceable member and at least partially through the guide means.The guide means thus forms a means relative to which at least one other part of the fastening means, such as the elongate member, is guided.

[0037] The guiding device may comprise more than one separate component or part which are assembled to form the guiding device.

[0038] The elastically compressible member may include any suitable compressible member for tensioning the first and second belt members and for absorbing possible expansion of the first and second containers. The elastically compressible member may include one or more of a compression spring, a conical disc spring (Belleville washer), or an elastomeric member (e.g., a rubber tube portion).

[0039] As described above, when the outer engagement member of the elongated member engages the inner engagement member of the apertured member, the resiliently compressible member is compressed.

[0040] During use of the fastening device, the elastically compressible member is compressed between the first abutment and the displaceable member or between the second abutment and the apertured member. Thus, the elastically compressible member is configured to directly or indirectly apply a force to the displaceable member to tension the first and second strap members.

[0041] The specific clamping force provided by the elastically compressible member is determined for each specific structural case and depends in particular on the relevant container to which the fastening device is fastened and the operating conditions under which the fastening device is used. In particular, the length reduction of the elastically compressible member and the force constant of the elastically compressible member determine the clamping force.

[0042] According to an embodiment, the guide device may include a first guide member, the first guide member being provided with a through hole concentric with the axis, wherein the second abutment may extend around the through hole, and wherein the elastically compressible member and the apertured member may be at least partially arranged within the first guide member. In this way, the elongated member may extend through the through hole of the first guide member and through the elastically compressible member to engage with the apertured member. Furthermore, the elastically compressible member and the apertured member may thus be conveniently arranged at least partially within the guide device.

[0043] According to an embodiment, the guiding device may comprise a second guiding member, and the displaceable member may be at least partially arranged within the second guiding member. In this way, the guiding device may be arranged for guiding the displaceable member.

[0044] According to an embodiment, the fastening device may comprise a sleeve arranged concentrically with the axis, and wherein the sleeve comprises the first abutment. In this way, when the elongated member is engaged with the apertured member, the elongated member may extend through the sleeve to move the first abutment in a direction towards the displaceable member.

[0045] According to an embodiment, the displaceable member may include a first pin and a second pin on opposite sides of the axis, and the first belt member may be connectable to the displaceable member via the first pin, and the second belt member may be connectable to the displaceable member via the second pin. In this way, a convenient connection between the fastening device and the first belt member and the second belt member may be provided. In addition, the first pin and the second pin may provide a pivotable connection between the displaceable member and the first belt member and the second belt member. Such a pivotable connection may ensure that the first belt member and the second belt member are properly aligned along the force component directed to / from the displaceable member. Therefore, the first belt member and the second belt member may not be subjected to bending loads.

[0046] According to an embodiment, the second guide member may include a first slot and a second slot, wherein the first pin may be slidably arranged in the first slot, and wherein the second pin may be slidably arranged in the second slot. In this way, when the displaceable member is displaced relative to the second guide member to tension the first and second band members when the elongated member is engaged with the apertured member, the movement of the first and second pins and thus the movement of the first and second band members may also be controlled along the first and second slots.

[0047] Furthermore, since the first and second band members are connected to the first and second pins and since the first and second pins are arranged in the first and second grooves during use of the fastening device, the first and second band members prevent the second guide member from rotating relative to the first guide member.

[0048] According to an embodiment, the guide device may include at least two support surfaces, each of the at least two support surfaces being configured to support one of the first container and the second container. In this way, the first container and the second container can be securely positioned relative to the fastening device when in use for fastening the container to the structure of the vehicle.

[0049] According to an embodiment, the foraminous member may be rotationally locked relative to the guide means. In this way, the engagement between the outer engagement member of the elongated member and the inner engagement member of the foraminous member may be facilitated. In particular, when the outer engagement member and the inner engagement member comprise threads, such engagement of the elongated member in the foraminous member may be facilitated.

[0050] According to another aspect, a gas fuel storage assembly is provided, which includes at least a first container and a second container configured to store gas, a bracket, a first belt member, a second belt member and a fastening device according to any one of the aspects and / or embodiments described herein, wherein the first belt member and the second belt member and the fastening device fix the first container and the second container to the bracket.

[0051] Since the fastening device discussed herein secures the first and second containers to the bracket, the gas fuel storage assembly provides easy tensioning of the first and second band members at least partially around the first and second containers configured for storing gas, while also limiting further strain in the first and second band members when the first and second containers expand. Thus, a cost-effective way of securing the first and second containers to the bracket is provided.

[0052] According to this aspect, the first container and the second container may be a first gas storage tank and a second gas storage tank. The gas stored in such gas storage tanks may be a compressed gas, such as CNG (Compressed Natural Gas) used as a fuel in a combustion engine.

[0053] According to another aspect, a vehicle is provided, the vehicle comprising a chassis and a gaseous fuel storage assembly according to any of the aspects and / or embodiments described herein connected to the chassis.

[0054] Since the vehicle includes the gas fuel storage assembly discussed herein, which in turn includes the fastening device discussed herein, easy tensioning of the first and second band members at least partially around the first and second containers is provided, while also limiting further strain in the first and second band members when the first and second containers expand. Thus, a cost-effective way of securing the first and second containers to the vehicle is provided.

[0055] According to another aspect, a method for assembling a gas fuel storage assembly is provided, the gas fuel storage assembly comprising at least a first container and a second container configured to store gas, a bracket, a first belt member, a second belt member, and a fastening device according to any of the aspects and / or embodiments described herein. The method comprises the following steps:

[0056] Fasten the guide of the fastening device to the bracket,

[0057] positioning the first container and the second container against the bracket,

[0058] placing the first and second belt members to extend at least partially around the first and second containers,

[0060] The elongated member of the fastening device is engaged with the apertured member of the fastening device such that the resiliently compressible member of the fastening device is compressed.

[0061] Thus, a method is provided to ensure a cost-effective manner of assembling a gas tank assembly, for example for securing a first gas tank and a second gas tank to a bracket.

[0062] The bracket may form part of a chassis of the vehicle, or may be mounted to a chassis of the vehicle.The vehicle may be a vehicle as discussed herein.

[0063] One or more steps of the method may be performed in an order different from that listed above.

[0090] It can be seen that the bracket 6 forms part of the structure of the vehicle 1. Another alternative could be that the chassis 3 of the vehicle 1 comprises the bracket 6.

[0091] In the embodiment shown, the bracket 6 is substantially L-shaped. However, the bracket may have any other shape making it suitable for connection to the structure of a vehicle.

[0092] The first and second strap members 8 , 10 and the fastening means 2 secure the first and second containers 4 ′, 4 ″ to the bracket 6 .

[0093] Merely by way of example, the first and second strap members 8, 10 may be made of sheet metal, braided metal wire, braided aramid or braided nylon (ie, a strong material with low elasticity suitable for holding the first and second containers 4', 4" securely against the bracket 6).

In this way, the first belt member 8 and the second belt member 10 can be guided from the fastening device 2 to extend at least partially around the corresponding container of the first container 4' and the second container 4".

[0099] Furthermore, in this way, the fastening device 2 can be fixed to the bracket via the guiding device.

[0100] Reference is further made below to various embodiments of the guide device 12 of the fastening device 2. Figure 3a-5c .

[0101] According to an embodiment of the gas fuel storage assembly 5, the first and second band members 8, 10 may be connected to the bracket 6.

The opposite second ends 8", 10" of the first belt member 8 and the second belt member 10 are connected to the bracket 6.

[0103] For example, each of the first and second belt ends 8 ′, 8 ″, 10 ′, 10 ″ of the first and second belt members 8 , 10 may be provided with a sling for the purpose of connecting to the displaceable member of the fastening device 2 and the bracket 6 .

[0104] The tension in the first and second strap members 8 , 10 ensures that the first and second containers 4 ′, 4 ″ are securely connected to the carrier 6 .

[0105] The gas fuel storage assembly 5 may include members for securely positioning the containers 4', 4" against the bracket 6 and / or against the first band member 8 and the second band member 10. For example, the foaming bands 14', 14" may be arranged around each of the first container 4' and the second container 4", between the bracket 6 and the first container 4' and the second container 4", and between the first band member 8 and the second band member 10 and the corresponding ones of the first container 4' and the second container 4".

[0106] exist Figure 2a-2c In the embodiment of the present invention, each fastening device 2 is shown as Figure 5a-5c Alternatively, the fastening device 2 may be a fastening device according to Figure 3a and 3b Embodiments or Figure 4a and 4b The fastening device 2 of the embodiment.

[0107] Figure 3a and 3b A fastening device 2 according to an embodiment is schematically shown. Figure 3a The fastening device 2 is shown in a pre-engaged state. Figure 3b The fastening device 2 is shown in an engaged state.

[0108] The fastening device 2 is a fastening device 2 for fastening the first container 4 ′ and the second container 4 ″ to a structure of the vehicle 1 . For example, the fastening device 2 may be a fastening device for a gas fuel storage assembly 5 of the vehicle 1 .

[0109] Thus, the fastening device 2 may be as described above with reference to Figure 1 and reference Figure 2a-2c The fastening device 2 discussed. Therefore, reference is also made hereinafter to Figure 1-2c .

[0110] The fastening device 2 comprises an elongated member 16 at least partially provided with an external engagement member 18. In the embodiment shown, the external engagement member 18 is a thread and thus the elongated member 16 may be a bolt or a screw. The elongated member extends along an axis 19.

[0111] The fastening device 2 further comprises a first abutment 20 arranged concentrically with the elongated member 16. In the embodiment shown, the first abutment 20 is provided by the elongated member 16 in the form of a threaded bolt having at least a portion of an axial surface of a head 21 of the elongated member 16.

[0112] Alternatively, for example, reference is made below Figure 5a-5c In the discussed embodiment, the first abutment 20 may form part of a separate component.

[0113] The fastening device 2 further comprises a displaceable member 22 connectable to a first band member 8 configured to extend at least partially around the first container 4' and a second band member 10 configured to extend at least partially around the second container 4".

[0114] The elongated member 16 extends through the displaceable member 22. The displaceable member 22 can be displaced along the axis 19 directly or indirectly through the elongated member when the elongated member 16 is displaced along the axis 19. In addition, when the first belt member 8 and the second belt member 10 move with the expansion and contraction of the first container 4' and / or the second container 4", the displaceable member 22 can be displaced along the axis 19 by the first belt member and the second belt member.

[0115] The fastening device 2 further comprises a guide device 12. The guide device 12 forms an anchoring point or an attachment point of the fastening device 2 to a structure, such as a structure of a vehicle, such as a carriage or a chassis. Thus, the guide device 12 is connectable to the structure.

[0116] In the embodiment shown, the guide device 12 comprises only one part. Alternatively, for example, as hereinafter referred to Figure 5a-5c In the discussed embodiment, the guide device 12 may include more than one part.

[0117] The guide device 12 comprises a second abutment 24 .

[0118] The guide device 12 is provided with a through hole 26 which is concentric with the axis 19 , and the second abutment 24 extends around the through hole 26 .

[0119] The elongated member 16 extends through the through hole 26 of the guide device 12. Thus, the elongated member 16 can be guided in the guide device 12.

[0120] The fastening device 2 further comprises an apertured member 28 at least partially provided with an inner engagement member 30 .

[0121] In the illustrated embodiment, the aperture member 28 is a nut and the internal engagement member 30 is a thread.

[0122] Therefore, if Figure 3b As shown in FIG. 1 , the outer engagement member 18 of the elongate member 16 in the form of an external thread is arranged to engage with the inner engagement member 30 of the apertured member 28 in the form of an internal thread.

[0123] The fastening device 2 further comprises a resiliently compressible member 32 positioned between the second abutment 24 and the apertured member 28. The resiliently compressible member 32 is schematically shown and may be, for example, an elastomeric member, such as a rubber member, but may be any other suitable compressible member.

[0124] The elongated member 16 extends through the resiliently compressible member 32 .

[0125] As described above, the elongate member 16 extends along the axis 19. The displaceable member 22, the guide means 12, the resiliently compressible member 32 and the apertured member 28 are all aligned along the axis 19.

[0126] See also Figure 3b The elongated member 16 extends through the displaceable member 22, at least partially through the guide device 12, and through the elastically compressible member 32 for engagement between the outer engaging member 18 of the elongated member 16 and the inner engaging member 30 of the apertured member 28 so as to compress the elastically compressible member 32.

[0127] As mentioned above, in Figure 3a , the fastening device 2 is shown in a pre-engaged state. The guide device 12 is fastened to a structure (not shown), the first and second belt members 8, 10 are positioned to extend at least partially around the first and second containers (not shown), and the elongated member 16 has been inserted through the displaceable member 22 and the through hole 26 of the guide device 12 to extend into the resiliently compressible member 32.

[0128] Thus, the outer engagement member 18 of the elongated member 16 and the inner engagement member 30 of the apertured member 28 are ready to engage with each other. In these embodiments, this means tightening the elongated member 16 in the apertured member 28, ie tightening the threaded bolt 16 in the nut 28.

[0129] exist Figure 3b In the embodiment, the fastening device 2 is shown in an engaged state. The outer engagement member 18 of the elongated member 16 and the inner engagement member 30 of the apertured member 28 are engaged with each other, ie, in these embodiments, the threaded bolt 16 and the nut 28 are tightened.

[0130] Thus, the first and second belt members 8, 10 are tensioned around at least a portion of the first and second containers (not shown) by the displaceable member 22 that has been displaced in the direction toward the apertured member 28. In addition, the elastically compressible member 32 has been compressed between the second abutment 24 and the apertured member 28.

[0131] More specifically, in the pre-engaged state, the threaded bolt 16 is movable relative to the displaceable member 22 and the guide device 12 in a direction along the axis 19. When the threaded bolt 16 is engaged with the nut 28, the first abutment 20 presses against the displaceable member 22, and the nut 28 presses the elastically compressible member 32 against the second abutment 24, thereby compressing the elastically compressible member 32.

[0132] Therefore, the elastically compressible member 32 indirectly applies a force to the displaceable member 22 via the bolt 16, which tensions the first and second band members 8, 10. In other words, the displaceable member 22 is biased by the elastically compressible member 32 to tension the first and second band members 8, 10.

[0133] The physical properties of resiliently compressible member 32 and the degree of compression of resiliently compressible member 32 determine the force applied to displaceable member 22 and the tension in first strap member 8 and second strap member 10 .

[0134] Figure 4a and 4b A fastening device 2 according to an embodiment is schematically shown.

[0135] The fastening device 2 of these embodiments is largely similar to Figure 3a and 3b Fastening device 2 of the embodiment. Therefore, the differences between the embodiments are mainly discussed below.

[0136] Likewise, the fastening device 2 is a fastening device 2 for fastening a first container and a second container to a structure of a vehicle. Likewise, the fastening device 2 comprises: an elongated member 16, the elongated member being at least partially provided with an external engagement member 18; a first abutment 20, the first abutment being arranged concentrically with the elongated member 16; a displaceable member 22, the displaceable member being connectable to a first belt member 8 configured to extend at least partially around the first container and a second belt member 10 configured to extend at least partially around the second container; a guide device 12, the guide device comprising a second abutment 24; a perforated member 28, the perforated member being at least partially provided with an internal engagement member 30; and an elastically compressible member 32.

[0137] Likewise, the elongated member 16 extends along the axis 19, and the displaceable member 22, the guide 12, the resiliently compressible member 32, and the apertured member 28 are aligned along the axis 19. Likewise, the elongated member 16 extends through the resiliently compressible member 32, through the displaceable member 22, and at least partially through the guide 12 for engagement between the outer engagement member 18 of the elongated member 16 and the inner engagement member 30 of the apertured member 28 for compressing the resiliently compressible member 32.

[0138] In these embodiments, a resiliently compressible member 32 is positioned between the first abutment 20 and the displaceable member 22. The resiliently compressible member 32 is shown schematically and may be, for example, an elastomeric member, such as a rubber member, but may be any other suitable compressible member.

[0139] exist Figure 4a, the fastening device 2 is shown in a pre-engaged state. The guide device 12 is fastened to a structure (not shown), the first and second belt members 8, 10 are positioned to extend at least partially around the first and second containers (not shown), and the elongated member 16 has been inserted through the resiliently compressible member 32, the displaceable member 22 and the through hole 26 of the guide device 12.

[0140] Thus, the outer engagement member 18 of the elongated member 16 and the inner engagement member 30 of the apertured member 28 are ready to engage with each other.

[0141] exist Figure 4b In the embodiment, the fastening device 2 is shown in an engaged state. The outer engagement member 18 of the elongated member 16 and the inner engagement member 30 of the apertured member 28 are engaged with each other, ie, in these embodiments, the threaded bolt 16 and the nut 28 are tightened.

[0142] Thus, the first and second belt members 8, 10 are tensioned around at least a portion of the first and second containers (not shown) by the displaceable member 22 displaced in the direction toward the aperture member 28. In addition, the elastically compressible member 32 has been compressed between the first abutment 21 and the displaceable member 22.

[0143] More specifically, in the pre-engaged state, the threaded bolt 16 is movable relative to the displaceable member 22 and the guide device 12 in the direction along the axis 19. When the threaded bolt 16 is engaged with the nut 28, the first abutment 20 presses the elastically compressible member 32 against the displaceable member 22, and the nut 28 presses against the second abutment 24, thereby compressing the elastically compressible member 32. Therefore, the elastically compressible member 32 directly applies a force to the displaceable member 22 by tightening the bolt 16, and the force tensions the first band member 8 and the second band member 10.

[0144] Likewise, the displaceable member 22 is biased by the resiliently compressible member 32 to tension the first and second strap members 8 , 10 .

[0145] Figure 5a-5c A fastening device 2 according to an embodiment is shown. Figure 5a The fastening device 2 is shown in an exploded view. Figure 5b The fastening device 2 is shown in a pre-engaged state. Figure 5c The fastening device 2 is shown in an engaged state.

[0146] The fastening device 2 is a fastening device 2 for fastening the first container and the second container to a structure of a vehicle. For example, the fastening device 2 may be a fastening device for a gas fuel storage assembly of a vehicle.

[0147] Thus, the fastening device 2 may be as described above with reference to Figure 1 And refer to Figure 2a-2c Therefore, in the following, reference is also made to the fastening device discussed. Figure 1-2c .

[0148] The fastening device 2 of these embodiments is largely similar to Figure 3a-4b Fastening device 2 of the embodiment. Therefore, the differences between the embodiments are mainly discussed below.

[0149] Similarly, the fastening device 2 includes: a slender member 16, which is at least partially provided with an external engaging member 18; a first abutting portion 20, which is concentrically arranged with the slender member 16; a displaceable member 22, which can be connected to a first belt member 8 configured to extend at least partially around the first container and a second belt member 10 configured to extend at least partially around the second container; a guiding device 12, which includes a second abutting portion 24; a perforated member 28, which is at least partially provided with an internal engaging member 30; and an elastically compressible member 32.

[0150] The first belt member 8 and the second belt member 10 are Figure 5b It is schematically indicated by a dotted line.

[0151] In these embodiments, the apertured member 28 is a pipe section provided with an internal engagement member 30 in the form of an internal thread.

[0152] The apertured member 28 is rotationally locked relative to the guide arrangement 12. Thus, the outer engagement member 18 of the elongated member 16 can engage with the inner engagement member 30 of the apertured member 30 without the apertured member 28 rotating.

[0153] The apertured member 28 is therefore rotationally locked but movable along the axis 19 .

[0154] As an example, the rotational locking can be achieved by corresponding shape-matching contours of the apertured member 28 and the guide device 12. Figure 5a-5c In the embodiment shown in , the rotational locking is achieved by the foraminous member 28 in the form of a tube portion having at least one flat outer surface 34, and the guide device 12 being provided with a hole 36 shaped so that the tube portion fits tightly therein. In this way, engaging the foraminous member 28 and the guide device 12 in the hole 36 will prevent the foraminous member 28 from rotating. Other shapes of the profile for rotationally locking the foraminous member 28 relative to the guide device 12 are possible, such as a triangular shape, a square shape or a hexagonal shape.

[0155] Likewise, the elongated member 16 extends along the axis 19, and the displaceable member 22, the guide 12, the resiliently compressible member 32, and the apertured member 28 are aligned along the axis 19. Likewise, the elongated member 16 extends through the displaceable member 22, at least partially through the guide 12, and through the resiliently compressible member 32 for engagement between the outer engagement member 18 of the elongated member 16 and the inner engagement member 30 of the apertured member 28 for compressing the resiliently compressible member 32.

[0156] Similar to Figure 3a and 3b In the embodiment of FIG. 5 , the elastically compressible member 32 is positioned between the second abutment 24 and the apertured member 28 .

[0157] According to these embodiments, the elastically compressible member 32 includes a helical spring and / or a conical disc spring (Belleville washer spring).

[0158] Alternatively, the resiliently compressible member 32 may include an elastomeric material, such as a rubber material.

[0159] The choice of resiliently compressible member 32 may depend on the specific use of the fastening device 2. By way of example only, an elastomeric material may provide a short compression distance and a relatively low compression force compared to a coil spring. A coil spring may provide a long compression distance and a low compression force compared to a conical disc spring, which may provide a short compression distance and a high compression force.

[0160] In these embodiments, the fastening device 2 comprises a sleeve 38 arranged concentrically with the axis 19. The sleeve 38 comprises the first abutment 20. The sleeve 38 is arranged between the head portion 21 of the elongated member 16 and the displaceable member 22.

[0161] Thus, when the elongate member 16 is engaged with the apertured member 28 , the elongate member 16 extends through the sleeve 38 such that the first abutment 20 abuts against the displaceable member 22 .

[0162] The guiding device 12 may be composed of one or more parts, for example Figure 3a-4b Only a portion of the embodiments.

[0163] exist Figure 5a-5b In the embodiment of the present invention, the guide device 12 comprises a first guide member 121. The first guide member 121 is provided with a through hole 26 concentric with the axis 19. The elastically compressible member 32 and the apertured member 28 are at least partially arranged in the first guide member 121. The second abutment 24 extends around the through hole 26.

[0164] The elongated member 16 extends through the through hole 26 of the first guide member 121 and through the elastically compressible member 32 to engage with the aperture member 28 .

[0165] The second abutment 24 is arranged for the resiliently compressible member 32 to abut thereagainst.

[0166] The guide device 12 further comprises a second guide member 122. The displaceable member 22 is at least partially arranged within the second guide member 122. In this way, the displaceable member 22 can be securely arranged in the guide device 12 and, furthermore, it can be guided in the guide device 12.

[0167] According to these embodiments, the guide device 12 comprises a distance member 123 arranged between the first guide member 121 and the second guide member 122. In this way, the second guide member 122 can be positioned relative to the first guide member 121 so that the displaceable member 22 is arranged in a suitable position so that the first belt member 8 and the second belt member 10 extend at least partially around the first container and the second container.

[0168] In the illustrated embodiment, the distance member 123 is hollow, and the elongated member 16 extends through the distance member 123 .

[0169] The distance member 123 may also protect the elongated member 16 as it extends through the distance member 123, so that the elongated member 123 is not obstructed in its movement relative to the guide means 12 during use of the fastening device 2. The movement of the elongated member 16 is caused by the movement of the first and second belt members 8, 10 as they follow the expansion and contraction of the first and second containers.

[0170] According to an alternative embodiment, the guide device 12 may comprise only the first guide member 121 and the second guide member 122. Another alternative may be that the guide device 12 comprises only the first guide member 121 and the distance member 123.

[0171] The displaceable member 22 includes a first pin 40 and a second pin 42 on opposite sides of the axis 19. Figure 5b As shown in , the first strap member 8 may be connected to the displaceable member 22 via a first pin 40 , and the second strap member 10 may be connected to the displaceable member 22 via a second pin 42 .

[0172] Thus, the first strap member 8 and the second strap member 10 can be connected to the displaceable member 22. The pivotable connection between the displaceable member and the first strap member 8 and the second strap member 10 can be achieved in this way to ensure that the first strap member 8 and the second strap member 10 are properly aligned along the force component directed to / from the displaceable member 22.

[0173] The second guide member 122 includes a first groove 44 and a second groove 46. More specifically, a body 47 of the second guide member 122 is provided with the first groove 44 and the second groove 46.

[0174] The first pin 40 is slidably disposed in the first slot 44 , and the second pin 42 is slidably disposed in the second slot 46 .

[0175] Thus, when the displaceable member 22 moves relative to the guide arrangement 12 and the second guide member 122 , the first and second pins 40 , 42 move along the first and second slots 44 , 46 in a controlled manner.

[0176] More specifically, when the elongated member 16 engages the apertured member 28 and the resiliently compressible member 32 is compressed, the displaceable member 22 displaces toward the apertured member 28 and the first guide member 121. During this displacement, the first and second pins 40 and 42 follow along the first and second slots 44 and 46.

[0177] In the illustrated embodiment, the first pin 40 and the second pin 42 are slidably arranged in further slots 44 ′, 46 ′ provided in the second guide member 122 .

[0178] See also Figure 5a , although not limited to the general idea of ​​utilizing the first pin 40 and the second pin 42 for connecting the first belt member 8 and the second belt member 10 to the displaceable member 22, in the illustrated embodiment, the displaceable member 22 includes additional first pins 48 and second pins 50 and link members 52-55 arranged between the first pin 40 and the second pin 42 and the additional first pin 48 and second pin 50.

[0179] In this way, the first pin 40 and the second pin 42 can move not only in parallel with the axis 19 but also in a direction perpendicular to the axis 19 .

[0180] exist Figure 5b , the fastening device 2 is shown in a pre-engaged state. The guide device 12 is fastened to a structure (not shown), the first and second belt members 8, 10 are positioned to extend at least partially around the first and second containers (not shown), and the elongated member 16 has been inserted through the displaceable member 22 and the through hole 26 of the guide device 12 to extend into the resiliently compressible member 32.

[0181] Thus, the outer engagement member 18 of the elongated member 16 and the inner engagement member 30 of the apertured member 28 are ready to engage with each other.

[0182] Note that the first pin 40 and the second pin 42 are positioned at respective end portions of the first slot 44 and the second slot 46 .

[0183] exist Figure 5c , the fastening device 2 is shown in an engaged state. The outer engagement member 18 of the elongated member 16 and the inner engagement member 30 of the apertured member 28 are engaged with each other.

[0184] Thus, the first belt member 8 and the second belt member 10 are tensioned around at least a portion of the first container and the second container (not shown) by the displaceable member 22 that has been displaced in the direction toward the first guide member 121 and the aperture member 28. In addition, the elastically compressible member 32 has been compressed between the second abutment 24 and the aperture member 28.

[0185] Note that with Figure 5b Compared to the positions of the pins 40, 42 in the first and second pins 40, 42, the first and second pins 40, 42 are positioned at respective opposite end portions of the first and second slots 44, 46. That is, the displaceable member 22 has been displaced relative to the guide device 12 and its second guide member 122.

[0186] The guide device 12 comprises at least two support surfaces 56, 58, see Figure 5a Each of the at least two support surfaces is configured to support one of a first container 4' and a second container 4", see e.g. Figure 2c Thus, when the fastening device 2 is in use, the first container 4 ′ and the second container 4 ″ are securely positioned relative to the fastening device 2 .

[0187] At least two support surfaces 56, 58 are configured to support the first container 4' and the second container 4", for example by having a curved shape with the same or similar curvature as the first container 4' and the second container 4", or by having any other shape suitable for supporting abutment against the first container 4' and the second container 4".

[0188] Figure 6 A method 100 for assembling a gaseous fuel storage assembly 5 is shown.

[0189] The gas fuel storage assembly 5 may be as described above with reference to Figure 2a-2c The gas fuel storage assembly 5 discussed. Therefore, hereinafter, reference is also made to Figure 2a-2c .

[0196] - securing 108 the first and second strap members 8, 10 to the fastening device 2 and the bracket 6, and

[0197] - Engaging 110 the elongated member of the fastening device 2 with the apertured member 28 of the fastening device 2 such that the resiliently compressible member 32 of the fastening device 2 is compressed.

[0198] The step of fixing 108 the first and second strap members 8, 10 may comprise fixing the respective first ends 8', 10' of the first and second strap members 8, 10 to the displaceable member 22 of the fastening device 2, for example to the first and second pins 40, 42. The opposite second ends 8", 10" of the first and second strap members 8, 10 may be fixed directly to the bracket 6, for example by screwing onto the bracket or via dedicated attachment members connected to the bracket 6. Such dedicated attachment members are configured for holding the ends of the first and second strap members 8, 10.
