DESCRIPTION OF EMBODIMENTS
[0200] With reference to
[0201] With reference to
[0202] As best shown in
[0203] As shown in
[0204] The sidewalls 20c of each fluid flow channel 20 are substantially elongate planar members. Without wishing to be bound by theory, it is thought that substantially planar sidewalls 20c prevent the formation of eddies, and thus substantially planar sidewalls 20c increase the efficiency of fluid-flow within each fluid flow channel 20.
[0205] As shown in
[0206] Each fluid flow channel 20 is configured such that fluid can flow from the fluid inlet 22 to the fluid outlet 50. Each tapered channel 20 allows fluid from the fluid inlet 22 to flow throughout the fluid flow channel 20, such that fluid can exit from the fluid outlet 50 throughout the whole of fluid flow channel 20. This exiting of fluid throughout the whole of the fluid flow channel 20 is used to provide fluid to the user of a mobility device over a wider area.
[0207] Without wishing to be bound by theory, it is thought that for a fixed supply of fluid to the fluid inlet 22, the absence of a tapered channel 20 will result in a reduced amount of fluid reaching the upper region 23a of each fluid flow channel 20 and an increase in the amount of fluid exiting the lower region 23b. This will then result in fluid being provided to the user over a reduced area. Subsequently, the cooling effect to the user will be reduced. The supply of fluid to the fluid inlet 22 will then need to be increased to achieve the same area of fluid provided to the user. This could result in, for example, the need for a larger fluid flow control apparatus 3 and/or a larger electrical power system or battery.
[0208] In this embodiment, as shown in
[0209] In this embodiment, and as best shown in
[0210] In this embodiment, the fluid is air.
[0211] As best shown in
[0212] In the embodiment illustrated and described here, the height of each fin 60, measured with reference to the depth axis 20z, has an arcuate shape from proximal to the fluid inlet 22, to distal to the fluid inlet 22. That is, the profile of each fin, measured from proximal to the fluid inlet 22, to distal to the fluid inlet 22, has an arcuate shape. The fins 60 prevent each fluid flow channel 20 from becoming partially or completely blocked by the weight of the user. The fins 60 provide support to the user and are made from a resilient material, such as, for example, polyurethane or a moulded elastomer.
[0213] As best shown in
[0214] The third support layer 90 inter alia protects, and provides support to, the fluid flow channels 20. For example, in use the support structure 1 will typically be attached to a mobility device, and the third support layer 90 minimises the wear and tear that would result from the fluid flow channels 20 contacting the mobility device. In some embodiments, the third support layer 90 minimises the wear and tear caused to other parts of the support structure 1 by preventing those parts of the support structure 1 from contacting the fluid flow channel 20. The third support layer 90 also contributes to the support and comfort provided to the user. As will be described in more detail below, in an alternative embodiment, the first support layer 70 may be folded over the third support layer 90. In this arrangement, at least a section of the first support layer 70 also provides protection, and provides support to, the fluid flow channels 20.
[0215] As best shown in
[0216] As shown in
[0217] The non-porous part 104 of the first fluid dispersion layer 100 can be used to better direct the flow of fluid from the fluid outlet 50 through the first fluid dispersion layer 100. As depicted in
[0218] In this embodiment, and as shown in
[0219] In this embodiment, the width of the porous part 102 of the first fluid dispersion layer 100 is greater than the width of the fluid outlet 50. The length of the porous part 102 of the first fluid dispersion layer 100 is greater than the length of the fluid outlet 50.
[0220] As best shown in
[0221] With reference to
[0222] As best shown in
[0223] As shown in
[0224] With reference to
[0225] With reference to
[0226] As best shown in
[0227] Electrical power is supplied to the fluid flow control apparatus 3 by way of a rechargeable battery (not shown), for example, a lithium ion battery. The battery is housed within the housing 7. In this embodiment, the battery is configured to provide a voltage of between approximately 2.4 Volts and 4.2 Volts. The battery is configured to provide a maximum current of 3 Amperes. The battery is configured such that, in use, the battery provides electrical power to the fluid flow control apparatus for between approximately 3 hours and 20 hours. The battery has a capacity of between approximately 7000 mAh and 9000 mAh.
[0228] As shown in
[0229] The support structure 1 illustrated and described here is able to cool a user of a mobility device by way of convection cooling. The support structure 1 also contributes to increased evaporation of moisture from the user by providing fluid to the user, and/or through the wicking mechanism of the fluid dispersion layers 100, 112.
[0230]
[0231]
[0232] In this embodiment, and as best shown in
[0233] Assembly of the alternative embodiment of the first, second and third support layers 70, 80, 90 as depicted in
[0234] In this embodiment, the second support layer 80 comprises a flexible section 81. The flexible section 81 allows a portion of the second support layer 80 to be folded. It should be understood that in some arrangements, the second support layer 80 need not have a flexible section 81. For example, if the second and third support layers 80, 90 are substantially equal in length, the upper region 70a of the first support structure 70 could be folded over the second and third support layers 80, 90, without the need for a flexible section 81 in the second support layer 80. In this embodiment, the flexible section 81 is a corrugated section. However, it should be understood that other types of flexible section could be used.
[0235] In the embodiment shown in
[0236] In this embodiment, the support structure 1 is arranged such that the support layer engagement portion 20d is engageable with the first support layer 70 and the second support layer 80. However, in other embodiments the support layer engagement portion 20d could engage with one or more of the first support layer 70, the second support layer 80 and the third support layer 90.
[0237] Each support layer engagement portion 20d is located on an outer surface 20g of the sidewall 20c of the fluid flow channel 20 that is in contact with or that faces the first support layer 70 and the second support layer 80. In this embodiment the support layer engagement portion 20d comprises one or more protrusions 20e located on the outer surface 20g of the sidewalls 20c of the fluid flow channel 20.
[0238] In this embodiment, each of the protrusions 20e are planar members or tabs. Each of the protrusions 20e are angled away from the outer surface 20g of the sidewalls 20c of the fluid flow channel 20. Each of the protrusions 20e could be angled away from the outer surface 20g of the sidewalls 20c of the fluid flow channel 20 by up to approximately 90. In this embodiment, the protrusions 20e slope generally towards the inlet 22 of the fluid flow channel 20.
[0239] It will be understood that in some embodiments, each of the protrusions 20e could be angled away from the outer surface 20g of the sidewalls 20c of the fluid flow channel 20 by up to 90. For the fluid flow channel 20 illustrated in
[0240] When the protrusions 20e engage with the first support layer 70 and the second support layer 80, the protrusions 20e mitigate movement of the first support layer 70 and the second support layer 80. During use of the support structure 1 by the end user, it is desirable to mitigate movement of the first, second and third support layers 70, 80 and 90 with respect to the fluid flow channels 20. This is primarily because it is undesirable for gaps between the fluid flow channels 20 and the support layers 70, 80 and 90 to be created during use of the support structure 1, as the end user is likely to experience discomfort as a result of this. The support structure engagement portion 20d is used in this embodiment to reduce the risk of this problem occurring by mitigating movement of the support layers 70, 80 and 90 with respect to the fluid flow channel 20.
[0241] With reference to
[0242] As best shown in
[0243] The rigid member 20f is configured to mitigate deformation of the fluid flow channel 20. The rigid member 20f is configured to increase the rigidity of the fluid flow channel 20. The rigid member 20f is configured to provide support to the fluid flow channel 20.
[0244]
[0245] As best shown in
[0246] The fluid flow control apparatus 3 comprises a frame member 9. The frame member 9 is secured to the housing 7 of the fluid flow control apparatus 3 by way of a glue (an example of an adhesive). The frame member 9 is a planar member. However, it should be understood that the frame member 9 could be a bar, a rod, a pole, a cable, or the like. In some embodiments, the frame member 9 may be integrally formed with the housing 7 of the fluid flow control apparatus 3.
[0247] The second fluid dispersion layer 112 is attachable to the frame member 9 by way of the fastening mechanism 114 of the second fluid dispersion layer 112.
[0248] In the embodiment illustrated in
[0249] The plug 13 comprises socket engagement portions. For each fluid flow channel 20, two of the socket engagement portions are resilient, flexible members 13 biased to be in a first position. In this embodiment, two of the socket engagement portions 13 comprise a substantially rounded rectangular cuboid.
[0250] Each socket 14 comprises two plug engaging portions, which in this embodiment are apertures 14 in each socket 14.
[0251] The plug 13 and the socket 14 are configured to be movable between an unlocked state and a locked state. When moved from the unlocked state to the locked state, the two socket engagement portions 13 move from the first position to a second position, and then from the second position to the first position. The end user can unlock the fluid flow channels 20 from the housing 7 of the fluid flow control apparatus 3 by pressing on the socket engagement portions 13.

[0253] The alternative embodiment of the first support layer 70 and the second support layer 80 shown in
[0254] In the embodiment shown in
[0255] When assembling the support structure 1, the fluid flow channels 20 can be placed into the fluid flow channel engagement portions 72 and 82, and the protrusions 20e of each fluid flow channel 20 can be inserted into the slits 74 and 84 of the first support layer 70 and the second support layer 80.
[0256] It should be understood that in some embodiments the slits could be slots, cut-out portions, or the like. Furthermore, in some embodiments at least one of the first support layer 70, the second support layer 80, and the third support layer 90 could be configured to accommodate at least a part of the support layer engagement portions 20d of the fluid flow channel 20. Moreover, whilst in this embodiment the first support layer 70 and the second support layer 80 each comprise eight slits 74 and 84, it should be understood that at least one of the first support layer 70, the second support layer 80 and the third support layer 90 could be configured to accommodate at least a part of the support layer engagement portion 20d of the fluid flow channel 20 by way of one or more slots, slits, cut-out portions, or the like.
[0257] In some embodiments, due to the length of the support structure 1, at least a part of the support structure 1 may be foldable to fit around a mobility device, or the like. At least a part of the support structure 1 may be foldable around a backrest of a mobility device, or the like. This allows the support structure 1 to be fitted to a range of different types and sizes of mobility devices. Furthermore, folding the support structure 1 in this way allows the support structure 1 to be secured to a mobility device 1 in a more reliable manner.
[0258] Modifications may be made to the foregoing embodiments within the scope of the present invention.
