Description

Support Frame

[0001] This invention relates to a support frame for air conditioning equipment, and in particular to an air conditioning equipment support frame, components thereof and methods of assembly and manufacture of at least some of the components.

BACKGROUND

[0002] Air conditioning equipment support frames are typically used on roof spaces or in other exposed outdoor spaces where there is a requirement to raise air conditioning equipment (such as air conditioning units) off the ground to prevent damage or disruption to the functioning of the air conditioning equipment from localised flooding, snowdrifts, blown leaf matter, or other blown matter liable to disrupt the functioning of the air conditioning equipment. Air conditioning equipment support frames may also provide additional stability and safety when locating air conditioning equipment by spreading the weight of the air conditioning equipment over a greater area.

[0003] Typically, such support frames are simple frames manufactured from elongate steel box section members having mounting plates welded to the ends thereof for securing elongate cross-members of the support frame to other elongate members. The elongate members to which the elongate cross-members are secured are sometimes referred to as end members. The mounting plates have defined therein bolt holes for bolting the cross- members to the other elongate members using pre-defined mounting holes along the other elongate members. The exact positioning of the cross-members on the other elongate members is limited by the positioning and frequency of the pre-defined mounting holes. The steel box section forming the legs of the support frames may be bent to provide a single member comprising two substantially vertical leg portions and a substantially horizontal linking portion at a predetermined height. It is not easy to provide a different height for the substantially horizontal linking portion without modifying the leg portions or providing an entirely new single member.

[0004] At least some current air conditioning equipment support frames can be time- consuming and complex to assemble. At least some current air conditioning equipment support frames can be difficult or impossible to adjust to configurations different from those in which the air conditioning equipment support frame is originally supplied. The present disclosure provides at least an alternative to air conditioning equipment support frames of the prior art and also provides components thereof.

BRIEF SUMMARY OF THE DISCLOSURE

[0005] In accordance with one aspect of the present disclosure there is provided an air conditioning equipment support frame connector for connecting a first elongate member of an air conditioning equipment support frame to a second elongate member of the air conditioning equipment support frame. The connector comprises a saddle portion formed from a plastics material and configured to be supported on the first elongate member. The connector further comprises a shelf portion formed from the plastics material or a further plastics material. The shelf portion is supported by the saddle portion and configured to receive and support an end of the second elongate member. The first and second elongate members are horizontal.

[0006] Thus, there is provided an efficient connector between elongate members in an air conditioning equipment support frame which can be formed from plastics. The connector supports the second elongate member with the first elongate member without direct connection of the second elongate member to the first elongate member. The first elongate member need not be modified, for example, by providing mounting holes, in order to connect to the second elongate member. The saddle portion and the shelf portion may be formed from the same or different plastics materials.

[0007] The parts of the air conditioning equipment support frame which form a platform for the air conditioning equipment may be substantially horizontal. In particular, the first elongate member and the second elongate member may be horizontal. The first elongate member and the second elongate member may be mutually transverse.

[0008] The shelf portion may have defined therein a shelf opening for receiving a fastener configured to secure the second elongate member to the shelf portion. Thus, the second elongate member may be secured to the first elongate member via the connector.

[0016] At least one of the shelf portion and the cover may further comprise at least one nut engaging member for fixing the rotational position of the nut during assembly of the air conditioning equipment support frame. Thus, the nut may be a captive nut and only a single torque-applying tool (such as a wrench or screwdriver) is required to secure the second elongate member to the connector.

[0017] The saddle portion may have defined therein at least one saddle opening for receiving a saddle fastener configured to be fastenable to clamp the saddle portion in position on the first elongate member. Thus, the saddle portion can be secured to the first elongate member over a range of longitudinal positions on the first elongate member.

[0018] The saddle portion may comprise a top portion configured to be supported on the first elongate member and two side portions arranged to extend from the top portion along a depth of the first elongate member. Thus, the saddle portion may easily be supported and located on the first elongate member. The opening may be an elongate slot extending along a one of the side portions from the intersection of the side portion with the top portion. The elongate slot may terminate within the side portion.

[0019] The saddle fastener may be a saddle nut and a saddle bolt. At least one of the shelf portion and the saddle portion may further comprise at least one saddle nut engaging member for fixing the rotational position of the saddle nut during assembly of the air conditioning equipment support frame. Thus, the saddle nut may be a captive nut and only a single torque-applying tool (such as a wrench or screwdriver) is required to secure the second elongate member to the connector.

DETAILED DESCRIPTION

[0043] Figure 1 is an illustration of an air conditioning equipment support frame in accordance with the present disclosure. The air conditioning equipment support frame 1 can be used for raising items of air conditioning equipment off a base level in order to prevent leaves, snow or other driftable matter from building up against a side of the air conditioning equipment, resulting in damage or disruption to the functioning of air conditioning equipment. A raised support frame for air conditioning equipment can also prevent damage due to flooding where the air conditioning equipment support frame 1 is positioned on the ground. The air conditioning equipment support frame 1 may also provide additional stability and safety for the mounting of air conditioning equipment by spreading the weight of the air conditioning equipment over a greater area. The air conditioning equipment support frame 1 comprises two pairs of leg sections formed from elongate leg members 30. Each elongate leg member 30 extends substantially vertically from a foot 50 provided at a lower end of the elongate leg member 30. Each pair of leg sections is connected at an upper end via an elongate longitudinal member 10. The elongate longitudinal member 10 runs substantially horizontally. An air conditioning equipment support frame corner connector 200 is provided at each end of the elongate longitudinal member 10 to connect to each respective elongate leg member 30. The elongate longitudinal members 10 are spaced by two elongate cross members 20, each elongate cross member 20 running horizontally between the elongate longitudinal members 10. An air conditioning equipment support frame connector 100 is provided at each end of each elongate cross member 20 to connect each elongate cross member 20 between the elongate longitudinal members 10. Two repositionable mounting points 40 are provided on each elongate cross member 20 to secure air conditioning equipment (not shown) to the air conditioning equipment support frame.

[0044] The elongate longitudinal members 10 and the elongate leg members 30 are each typically formed from metal box section, for example steel alloy square box section. It will be appreciated that other profile shapes are possible, such as tubular section. It will also be appreciated that other materials are possible, such as aluminium. The elongate cross members 20 are typically formed from channel section, comprising a channel base portion, with two channel side portions extending one each from each edge of the channel base portions. An upper end of each channel side portion has extending therefrom an overturned section forming an inwardly projecting lip, whereby to provide a wider channel between an end of the overturned section and the channel base section compared to the spacing between the two overturned sections. The channel base portion typically has defined therein a plurality of regularly spaced slots. It will be appreciated that the plurality of regularly spaced slots is a standard feature of support members in the field. The repositionable mounting points 40 typically comprise a metal plate sized to be held captively between the overturned sections and the base section of the elongate cross member 20. The mounting point 40 is also provided with a resilient washer in the form of a rubber washer to vibrationally insulate the air conditioning equipment support frame 1 from any vibrations in the air conditioning equipment.

[0045] Each foot 50 is typically a pre-formed plastics support foot which can optionally be secured to the mounting surface in order to secure the air conditioning equipment support frame 1 to a fixed anchor point.

[0046] Each air conditioning equipment support frame connector 100 is slidably supported on the associated elongate longitudinal member 10, whereby the separation distance between the two elongate cross members 20 can be varied. Both the air conditioning equipment support frame connector 100 and the air conditioning equipment support frame corner connector are formed from a plastics material. In this particular embodiment, the air conditioning equipment support frame connector 100 is assembled from a first component 101 and a cover 150 (see Figures 5 to 7). The air conditioning equipment support frame corner connector 200 is assembled from three separate moulded plastics components.

[0047] Figure 2 is an illustration of a first component for an air conditioning equipment support frame connector of the air conditioning equipment support frame of Figure 1. Figures 3 and 4 are further views of the first component shown in Figure 2. Although the air conditioning equipment support frame 1 shown in Figure 1 shows an air conditioning support frame connector 100 formed from two separate plastics components, it will be appreciated that in at least some embodiments the air conditioning support frame connector may be realised using only the first component 101 shown in Figure 2. The first component 101 of the air conditioning equipment support frame connector 100 comprises a saddle portion 110. The saddle portion 110 comprises a saddle top portion 112. A saddle side portion 114 extends downwardly from each side of the saddle top portion 112.

Together, the saddle top portion and saddle side portions 1 14 define a first channel that is open opposite to the saddle top portion 1 12 and open at respective ends of the saddle portion 110. The saddle portion 1 10 is configured to be supported on a first elongate member in the form of an elongate longitudinal member 10 (see Figure 1). In particular, the first channel is slid on to the elongate longitudinal member 10 such that a bottom surface of the saddle top portion 1 12 is brought to rest on an upper surface of the elongate longitudinal member 10. The first channel and the elongate longitudinal member 10 are thus co-axially aligned. The saddle side portions 114 help to guide the first component 101 into position on the elongate longitudinal member 10, and resist twisting of the first component 101 relative to the elongate longitudinal member 10. However, it will be understood that the saddle side portions 114 could be omitted, with the first component 101 being supported on the elongate longitudinal member 10 via the engagement of the bottom surface of the saddle top portion 1 12 on the upper surface of the elongate longitudinal member 10 alone.

[0048] A shelf portion 120 extends from each side of the saddle portion 110. In particular, the shelf portions 120 each extend laterally from each saddle side portion 1 14 of the saddle portion 110. The shelf portion 120 is therefore supported by the saddle portion 1 10. Each shelf portion 120 comprises a shelf base portion 122 and first and second guide members each in the form of shelf side portions 124 each extending upwardly from a respective edge of the shelf base portion 122 in an opposite sense to the saddle side portions 1 14. Together, each shelf base portion 122 and associated shelf side portions 124 define a respective lateral channel that is open opposite to the shelf base portion 122 and open at an end of the shelf portion 120 laterally away from the saddle portion 110. The shelf portion 120 is configured to receive and support an end of a second elongate member in the form of an elongate cross member 20. In particular, an and of an elongate cross member 20 may be slid in to a lateral channel such that a bottom surface of the end of the elongate cross member 20 is brought to rest on an upper surface of the shelf base portion 122. The lateral channel and the elongate cross member 20 are thus co-axially aligned. The shelf side portions 124 help to guide the elongate cross member 20 into position on the first component 101 , and resist twisting of the elongate cross member 20 relative to the first component 101. However, it will be understood that the shelf side portions 124 could be omitted, with the end of the elongate cross member 20 being supported on the first component 101 via the engagement of the bottom surface of the elongate cross member 20 on the upper surface of the shelf base portion 122 alone.

[0049] As illustrated, the shelf portions 120 extend transversely to the saddle portion 1 10, and as such the respective axes of the channels formed by the saddle portion 110 on the one hand and by the shelf portions 120 on the other hand are perpendicular to one another. The elongate cross members 20 are thus disposed perpendicular to the elongate longitudinal member 10. In use, these axes would each be horizontal, so that the weight of the equipment that is to be supported by the frame would be distributed evenly on the frame. The elongate cross members 20 and the elongate longitudinal members 10 are disposed with their respective axes in parallel planes. In certain embodiments, the respective planes may be coincident.

[0050] Only a single shelf portion 120 may be provided, if it is only required for an elongate cross member 20 to be supported on one side of an elongate longitudinal member 10, as in the example illustrated in Figure 1. However, the provision of shelf portions 120 on either side of the saddle portion 1 10 allows for another elongate cross member 20 to be supported to extend from the other side of the elongate longitudinal member 10, thereby allowing for the support of larger pieces of equipment and also enabling a more modular form of construction of the support frame.

[0051] Each shelf base portion 122 has defined therein a shelf opening in the form of an elongate shelf slot 126. The elongate shelf slot 126 allows a fastener (not shown) to be used to secure the elongate cross member 20 to the shelf portion 120.

[0052] Each saddle side portion 114 has defined therein a saddle opening in the form of an elongate saddle slot 1 16. The elongate saddle slot 1 16 is positioned to allow a fastener (not shown) to pass around the outside of the elongate longitudinal member 10 and to engage with both saddle side portions 114, whereby to clamp the saddle side portions 1 14 against the elongate longitudinal member 10. In this way, the position of the air conditioning equipment support frame connector 100 on the elongate longitudinal member 10 can be substantially fixed. For the case where the fasteners are screw fasteners, such as bolts, the first component 101 further comprises at least one nut engaging member in the form of a shelf portion nut engaging surface 128 and a saddle portion nut engaging surface 1 18. Each of the nut engaging surfaces 118, 128 is positioned to rotationally fix the position of a nut, whereby to allow easy tightening of a screw fastener by an installer using only a single torque-applying tool (such as a screwdriver or wrench).

[0053] Figure 5 is an illustration of a cover 150 configured to engage with the first component 101 shown in Figures 2 to 4. Figures 6 and 7 are further views of the cover shown in Figure 5. As described hereinbefore, the air conditioning equipment support frame connector 100 preferably comprises a cover 150. The cover 150 is sized to fit over at least the shelf portion 120 of the first component 101. The use of the cover 150 increases both the safety of the air conditioning equipment support frame connector 100 and the apparent safety and robustness of the air conditioning equipment support frame connector 100. The cover 150 comprises a saddle cover portion 160 arranged to at least partially surround the saddle portion of the first component when the cover 150 is positioned on the first component 101. The cover 150 further comprises a shelf cover portion 170 arranged to cover the shelf portion 120 of the first component and define, together with the shelf portion 120, an elongate cross member receiving cavity. In practice, it will be appreciated that the elongate cross member 20 may be positioned on the shelf portion 120 before the cover 150 is positioned on the first component 101. The shelf cover portion 170 comprises a top portion 172, and first and second cover side members 174, the first and second cover side members 174 each extending from respective ends of the top portion 172, and arranged to slidably surround the shelf side portions 124 when the cover 150 is positioned on the first component 101.

[0054] The top portion 172 of the shelf cover portion 170 has defined therein a cover opening in the form of an elongate cover slot 176. The elongate cover slot 176 allows a fastener (not shown) to be used to secure the elongate cross member 20 to the shelf cover portion 170. It will be appreciated that the same fastener may be used to secure the elongate cross member 20 to both the shelf cover portion 170 of the cover 150 and to the shelf portion 120 of the first component.

[0055] In this particular embodiment, a spacing between facing surfaces of the first and second cover side members 174 is just less than a total width of outer opposing faces of the shelf side portions 124 for each shelf portion 120. In this way, as the cover 150 is slid over the first component 101 , the first and second cover side members 174 push against the shelf side portions 124 and at least partially clamp the elongate cross member 20 within the shelf portion 120.

[0056] Both the first component 101 and the cover 150 are typically formed from a plastics material by a moulding process. Advantageously, the first component 101 and the cover 150 can each be formed from a two-part mould in a single moulding process. It will be appreciated that appropriate drafting angles and material thicknesses can be chosen without departing from the scope of the disclosure.

[0057] The air conditioning equipment support frame 1 uses air conditioning support frame corner connectors 200 to connect the elongate leg members 30 to the elongate longitudinal members 10. Figure 8 is an illustration of an elongate leg member insertion component 210 of the air conditioning equipment support frame corner connector 200 of the air conditioning equipment support frame 1 of Figure 1. The elongate leg member insertion component 210 is arranged to be inserted partially within the hollow section of the elongate leg member 30. The elongate leg member insertion component 210 is typically formed from a plastics material and comprises a flange portion 212 sized to prevent full insertion of the elongate leg member insertion component 210 within the elongate leg member 30. A topside of the flange portion 212 is provided with a connecting portion in the form of a locating eyelet portion 214 for engagement with at least one further component of the air conditioning equipment support frame corner connector 200. An elongate leg member connecting portion in the form of a protruding portion 216 extends from an underside of the flange portion 212. The protruding portion 216 comprises a first portion 218 sized to fit snuggly within an internal space of the elongate leg member 30. Beyond the first portion 218, is provided a second portion 220 having a reduced width and defining an elongate slot 222 for securing the elongate leg member insertion component 210 within the elongate leg member 30 by engagement with a fastener passing through a

corresponding hole defined in the elongate leg member 30. The second portion 220 further comprises a lip member 224 increasing an effective width of the second portion 220 of the elongate leg member insertion component 210. The degree of insertion of the elongate leg member insertion component 210 within an elongate leg member 30 is easily controlled by altering the position where the fastener passes through the slot. In this way, it will be appreciated that the effective length of each leg of the air conditioning equipment support frame 1 can be altered slightly to cope with the situation where the air conditioning equipment support frame 1 is positioned on uneven terrain.

[0058] Figure 9 is an illustration of a further component 240 of the air conditioning equipment support frame corner connector 200 of the air conditioning equipment support frame 1 of Figure 1. The further component 240 comprises an elongate longitudinal member connecting portion in the form of an elongate longitudinal member protruding portion 244. The elongate longitudinal member protruding portion 244 has a width sized to fit within the elongate longitudinal member 10. The elongate longitudinal member protruding portion 244 has an opening 252 defined therein for securing the elongate longitudinal member protruding portion 244 within the elongate longitudinal member 10.
