AIR VENT

Description

[0001] The present invention relates to an air vent for ventilating an enclosed space within a building structure to an external environment, such as to the atmospheric environment external of a building structure, and in particular which allows for installation of the vent from within the building structure.

[0002] Various vents exist for ventilating building structures, and which allow for installation from within the building structure. One such vent is disclosed in GB-A-2467109, where the outer, peripheral sealing flange of the external cover tapers rearwardly, such that on installing the vent, by pushing though a channel, the sealing flange is deflected inwardly by the internal surface of the channel.

[0003] These existing vents suffer from a number of drawbacks, however, and it is an aim of the present invention to provide an improved vent.

[0004] GB-A-2464294 discloses an adjustable ventilation coupling for enabling air flow to/from a wall, ceiling or floor cavity of a structure, comprising adaptors arranged to engage in use with respective external and internal vents, and connectors which connect the adaptors to an air transfer duct so that the lateral spacing can be varied whilst maintaining the adaptors in a desired orientation.

[0005] In one aspect the present invention provides an air vent for providing ventilation through a bore in a building structure according to claim 1.

[0006] Preferred embodiments of the present invention will now be described hereinbelow with reference to the accompanying drawings, in which:

[0018] In this embodiment the at least one engagement section 53 extends around only part of the periphery of the tubular member 45, whereby the first and second bodies 3, 5, when in a first angular relation, provide for inter-engagement of the engagement sections 23, 53, and, when in a second angular relation, provide for dis-engagement of the engagement sections 23, 53, such that the body sections 3, 5 can be freely moved axially in relation to one another.

[0019] In this embodiment the tubular member 45 includes first and second engagement sections 53 which extend around only part of the periphery of the tubular member 45, here in first and second segments which are arranged in spaced annular relation. In this embodiment the first and second engagement sections 53 are arranged in opposed, symmetrical relation, here each extending over a 45 degree arc of the peripheral surface of the tubular member 45.

[0020] In this embodiment the at least one engagement section 53 comprises at least one engagement element 55 which provide for engagement with counterpart engagement elements 25 on the first body 3.

[0021] In this embodiment the at least one engagement section 53 comprises a plurality of engagement elements 55 which are arranged in spaced relation along the axial length of the tubular member 45 and provide for engagement with counterpart engagement elements 25 on the first body 3.

[0022] In this embodiment, as illustrated in Figure 6, the engagement elements 55 each comprise a tooth or detent, here having a first, tapered forward surface 61, which allows the counterpart engagement elements 25 of the first body 3 to pass relatively easily thereover when the first and second bodies 3, 5 are moved in axial relation to collapse the same, and a second, locking surface 63, against which the counterpart engagement elements 25 of the first body 3 are locked to prevent the first body 3 being withdrawn from the second body 5; with such withdrawal requiring rotation of the first body 3 in relation to the second body 5, as described hereinabove.

[0023] In this embodiment the at least one engagement section 53 is resiliently coupled to a main section of the tubular body 45, here by forming the at least one engagement section 53 as a tab, such as to facilitate sliding of the counterpart engagement elements 25, 55 thereover when the first and second bodies 3, 5 are moved in axial relation to collapse the same.

[0024] In this embodiment the tubular member 45 includes projections 65 at the one, inner end 47 thereof which can be cut in accordance with the width of the wall W, such that the length of the second body 5 can be made shorter than the width of the wall W but such that the one, inner end of the second body 5 extends into the inner leaf L1 across the cavity C,

[0025] In this embodiment the attachment member 51 defines a recess 71 in which the vent cover assembly 7 is slideably disposed between a first, withdrawn or non-deployed position, as illustrated in Figure 1, and a second, deployed position, as illustrated in Figure 2.

[0026] In this embodiment the attachment member 51 includes a stop 73, here in the form of an annular flange, against which the vent cover assembly 7 is disposed in the withdrawn or non-deployed position.

[0027] In this embodiment the attachment member 51 includes at least one aperture 75 therein, which receives and through which extends the locking element 85 of at least one locking member 83 of the cover unit 7 when the cover unit 7 is moved to the deployed position.

[0028] In this embodiment the attachment member 51 includes at least one guide 77, here in the form of a path or track, which receives the at least one locking member 83 of the cover unit 7 and acts to guide the locking element 85 of the at least one locking member 83 to the at least one aperture 75.

[0029] In this embodiment the attachment member 51 includes at least one detent 79 which is located outwardly of the at least one aperture 75, and is configured to prevent the locking element 85 of the at least one locking member 83 being moved outwardly beyond the at least one aperture 75.

[0030] In this embodiment the attachment member 51 includes a plurality of locking apertures 75 therein, here arranged in spaced annular relation, through which extend the locking elements 85 of a plurality of locking members 83 of the cover unit 7 when the cover unit 7 is moved to the deployed position.

[0031] In this embodiment the attachment member 51 includes a plurality of guides 77, which receive the locking members 83 of the cover unit 7 and act to guide the locking elements 85 of the locking members 83 to the apertures 75.

[0032] In this embodiment the attachment member 51 includes a plurality of detents 77 which are located outwardly of the respective apertures 75.

[0033] The cover unit 7 comprises a body member 81 which is slideably disposed within the attachment member 51 of the second body 5, and at least one locking member 83 which is configured to extend through the at least one aperture 75 in the attachment member 51 when the cover unit 7 is in the deployed position.

[0034] In this embodiment the at least one locking member 83 comprises a locking element 85 which is radially-outwardly biased to the body member 81, such that the locking element 85 is disposed in a radially-inward position when the cover unit 7 is in the non-deployed position, as illustrated in Figures 7 and 8, with the distal end of the locking element 85 being located in the at least one guide 77 in the attachment member 51, and disposed in a radially-outward position when the cover unit 7 is in the deployed position, as illustrated in Figures 9 and 10, with the locking element 85 extending through the at least one aperture 75 in the attachment member 51 and locking the cover unit 7 in the deployed position.

[0035] In this embodiment the body member 81 includes at least one recess 87 at the periphery thereof, and the at least one locking member 83 includes a biasing element 89, here a compression spring, which is disposed within the at least one recess 87 and acts to bias the locking element 85 radially outwardly, such as to cause the locking element 85 to extend through the respective aperture 75 in the attachment member 51 when the cover unit 7 is in the deployed position.

[0036] In this embodiment the cover unit 7 includes a plurality of locking members 83, which are configured to extend through respective ones of the plurality of the apertures 75 in the attachment member 51 of the second body 5, such as to lock the cover unit 7 in the deployed position.

[0037] The cover unit 7 further comprises an annular seal 91 which is configured to provide a weathertight seal about the periphery of the bore B formed in the wall W.

[0038] In this embodiment the seal 91 comprises a support element 93 which is fixed to the body member 81, and a seal element 95, which is configurable between a withdrawn or non-deployed configuration, as illustrated in Figures 7 and 8, in which the seal element 95 is disposed radially inwardly of the attachment member 51 of the second body 5, and a deployed configuration, as illustrated in Figures 9 and 10, in which the seal element 95 extends radially outwardly of the attachment member 51 of the second body 5, such that the seal element 95 is engageable with an outer surface of the wall W about the bore B formed in the wall W.

[0039] In this embodiment the seal element 95 is formed of a resilient material and defines a frusto-conical section which tapers outwardly and rearwardly from a forward edge thereof when in the deployed configuration, as illustrated in Figures 9 and 10, and is folded forwardly and inwardly when in the non-deployed configuration, as illustrated in Figures 7 and 8.

[0040] In this embodiment the seal member 91 is formed of a rubber or elastomer, here a thermoplastic elastomer.

[0041] In this embodiment the body member 81 provides a grille 97, here a slatted grille, through which passes an air flow.

[0042] Fitting of the air vent in a wall W, here a cavity wall, will be described hereinbelow with reference to Figures 11(a) to (e).

[0043] In a first step, as illustrated in Figure 11(a), a bore B of predetermined diameter is formed in the wall W, here extending through the inner and outer leaves L1, L2.

[0044] The operative then measures the thickness of the wall W in order to ensure that the length of the second body 5, when fitted, is such that the proximal end 47 of the second body 5 will be located within the inner leaf L1. If the second body 5 needs to be shortened, the projections 65 at the proximal end 47 of the second body 5 are cut accordingly.

[0045] Subsequently, as illustrated in Figure 11(b), a holding tool 101 is attached to the cover unit 7, and the air vent, with the cover unit 7 in the withdrawn or non-deployed position and the first engagement sections 23, 53 of the first and second bodies 3, 5 disengaged, is inserted into the bore B in the wall W, such that the attachment member 51 at the distal end 49 of the second body 5 extends beyond the outer surface of the wall W. In this position, the apertures 75 in the attachment member 51 are located externally of the wall W.

[0046] In this embodiment the holding tool 101 is a line, such as a string line.

[0047] Then, as illustrated in Figure 11(c), using a pusher tool 103, the cover unit 7 is moved from the withdrawn position to the deployed position, in which the locking elements 85 of the locking members 83 are biased to extend through the apertures 75 in the attachment member 51 and the seal element 95 of the seal member 91 adopts the deployed position, providing a frusto-conical element which is outwardly and rearwardly flared.

[0048] In this embodiment the pusher tool 103 is a rod, here formed by part of the packaging 201 in which the air vent is supplied.

[0049] In one embodiment, as illustrated in Figure 12, the packaging 201 is configured such that part of the packaging 201, here part of the lid 203, is detachable along a separation line 204, and pre-configured with fold lines 205 to form the pusher tool 103 by folding.

[0050] In this embodiment the packaging 201 is cardboard packaging.

[0051] In one embodiment the holding and pusher tools 101, 103 could be provided by a single tool which provides a rod and an engagement element at the distal end.

[0052] Then, as illustrated in Figure 11(d), the holding tool 101 is pulled rearwardly in order to draw the cover unit 7 and the body members 3, 5 attached thereto rearwardly or inwardly. As will be seen, the locking elements 85, which project radially outwardly of the attachment member 51 engage the outer surface of the wall W when the cover unit 7 is drawn rearwardly, thereby fixing the cover unit 7 in relation to the wall W, and, in this position, the seal element 95 of the seal member 91 engages the outer surface of the wall W, such as to provide a weathertight seal around the aperture as defined by the bore B in the wall W.

[0053] Subsequently, as illustrated in Figure 11(e), while retaining the holding tool 101, the first body 3 is rotated in relation to the second body 5 such that the first engagement sections 23, 53 of the first and second bodies 3, 5 are engaged, and moved axially into the bore B in the wall W until the flange 37 as provided by the stop 21 engages the inner surface of the wall W. In this position, the air vent is held in position by engagement of the flange 37 against the inner wall and the locking elements 85 against the outer surface of the wall W, and the bodies 3, 5 are held in relative position by the respective engagement sections 23, 53 thereof, which cannot be released until the first body 3 is rotated in relation to the second body 5.

[0054] In this embodiment, as illustrated in Figure 11(f), the first body 3 is fixed to the wall using fixings 107 which pass though the apertures 39 in the flange 37.

[0055] Finally, it will be understood that the present invention has been described in its preferred embodiments and can be modified in many different ways without departing from the scope of the invention as defined by the appended claims.
