Description

Pivot mounts for panels Field of the Invention This invention relates generally to pivot mounts for panels and, more specifically, adjustable pivot mounts for adjusting at least one of upper and lower pivot points of a door, window panel or the like to correct the alignment thereof within a frame.

Background of the Invention Door, window panels and the like may be retained within a frame having a head and a sill. However, slight misalignments, including of the frame and especially compounded by folding panel arrangements may cause the panels to stick.

Various arrangements exist for adjusting the pivot points of the panel pivots.

One such arrangement comprises a mounting block to which the panel is pivotally mounted. The block locates within a channel, either at the sill or the head and may be tapped along the channel to vary the position of the respective pivot point. However, tapping of a mounting block along the channel is difficult and inaccurate. Also, the block tends to dislocate over time.

Another such arrangement seeking to overcome such difficulties is disclosed in Australian laid open patent AU 199947373 B2 [Spork, 16 March 2000], hereafter referred to as D1 which discloses an adjustable pivot for folding panels which has a mounting member which affixes to the sill frame and which has a slide block retained thereby to which the panels are mounted. A screw interfaces the slide block and the mounting member to adjust the pivot point.

However, we found that the particular arrangement has certain limitations including difficulty of access especially when recessed and, therefore we devised the present invention seeks to provide a way, which will overcome or substantially ameliorate at least some of the deficiencies of the prior art, or to at least provide an alternative.

It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.

Summary of the Disclosure There is provided herein a pivot mount for a panel having a housing and a pivot member slidably engaged by the housing. The panel is pivotally engaged by the pivot member.

A threaded shaft is rotatably engaged between the housing and the pivot member to rotate about a threaded shaft rotational axis. Rotation of the threaded shaft about the threaded shaft rotational axis causes the pivot member to slide with respect to the housing. In embodiments, the pivot member can slide to allow for adjustment of approximately 1 cm.

The mount further comprises an adjustment member rotatably engaged by the housing to rotate about an adjustment member rotational axis such that the adjustment member rotational axis and the threaded shaft rotational axis are nonparallel. In a preferred embodiment, the threaded shaft rotational axis and the adjustment member rotational axis are orthogonal.

The adjustment member is operably coupled to the threaded shaft such that rotation of the adjustment member causes the threaded shaft to rotate. In a preferred embodiment, the threaded shaft and the adjustment member comprises bevel gearing therebetween. The use of such bevel gearing allows for adjustment in an easily accessible direction parallel to pivot axis, which is favorite to adjustment operation.

The adjustment member exposes a tool engagement for turning the adjustment member in use. A preferred embodiment of the tool engagement is an Allen key socket.

Furthermore, the tool engagement may be exposed through an upper surface of the housing adjacent the pivot mount exposed thereby. Furthermore, the tool engagement may be more than 1 cm away from the pivot mount at the closest point for ease of access.

With such a configuration, the tool engagement is conveniently accessible through an upper surface of the housing for the pivot point adjustment thereof with an Allen key, negating the more difficult requirement to insert tools in alignment with the shaft, especially within a recessed channel as to prior art arrangements such as D1. Furthermore, the location of the Allen key socket and the utilisation of an Allen key may allow for adjustment of the pivot point without obstruction of the adjacent panel.

Rotation of the adjustment member with an Allen key causes the threaded shaft to rotate and the pivot member to slide with respect to the housing, thereby adjusting the pivot point of the panel.

The gearing may comprise resilient stainless steel whereas the remainder of the housing may comprise plastic.

In embodiments, the housing may be of bifurcated construction comprising a base plate and substantially rectangular cowl coupled thereto, thereby not only being of a more aesthetic unitary construction but also reducing dust ingress.

Furthermore, housing may be elongate and define a horizontal surface away from the pivot member which has fastener apertures therethrough. In this way, the housing may be secured to the frame or sill only by fasteners through these distally located fastener apertures.

These fastener apertures are easily accessible with a Phillips screwdriver or the like by being perpendicularly orientated and away from the pivot axis, thereby simplifying speeding installation of the pivot mount.

The adjustment member may define a cylindrical bearing which is journaled within an aperture through the surface of the cowl. The cylindrical bearing exposes the tool engagement through the surface. An opposite end of the adjustment member may be journaled within an annular bearing, which may be defined by the base plate, thereby supporting the adjustment member at either end and simplifying the construction of the mount. Furthermore, the upper surface of the cylindrical portion may lie substantially flush with the upper surface of the housing, thereby aesthetically aligning the tool engagement.

According to one aspect, there is provided a pivot mount for a panel, the mount comprising a housing, a pivot member slidably engaged with respect to t he housing and configured for pivotal engagement of the panel about a pivot axis, a threaded shaft rotatably engaged between the housing and the pivot member to rotate about a threaded shaft rotational axis such that rotation of the threaded shaft about the threaded shaft rotational axis cause the pivot member to slide with respect to the housing, wherein the mount further comprises an adjustment member rotatably engaged by the housing to rotate about an adjustment member rotational axis such that the adjustment member rotational axis and the threaded shaft rotational axis are non-parallel and wherein the adjustment member is operably coupled to the threaded shaft such that rotation of the adjustment member causes the threaded shaft to rotate.

The adjustment member may define a cylindrical bearing journaled within an aperture of a surface of the housing.

The adjustment member may define an adjustment member shaft and wherein a lower end of the shaft may be retained within an annular bearing opposite the aperture.

The adjustment member may comprise a bevel gear between the tool engagement of the adjustment member shaft.

The housing may be of a bifurcated construction comprising a base plate and a cowl attached thereto.

The base plate and the cowl may define cooperative bearing protrusions defining at least one bearing within which the threaded shaft may be journaled.

The at least one bearing may be two bearings located either side of the pivot member.

An undersurface of the pivot member may be planar and slides along a corresponding planar portion of the base plate.

The housing may be elongate and wherein the cowl may define a channel at least partway therealong and wherein the pivot member extends from the channel.

The pivot member may comprise planar side cutaways which engage against the corresponding linear inner side edges of the channel.

Description of Embodiments Figure 1 shows a pivot set 100 for a panel 105 comprising an upper pivot mount 103 and a lower pivot mount 104.

With reference to Figure 2, each pivot mount 103, 104 engages a respective hinge leaf 106 each having a planar portion 108 and screw hole apertures 109 therethrough for affixation to an end of the panel 105. Each leaf 106 may further comprise a cylindrical portion 107 which rotates about a pivot axis with respect to the respective mount 103, 104.

The lower mount 104 may be mounted to a sill of a frame and the upper mount 103 to the head of the frame so as to pivotally engage the panel 105 therebetween. In embodiments, the panel 105 may hingedly engage further panels 105 along the frame in bifold configuration.

Each pivot mount 103, 104 is adjustable to the pivot axis thereof to exactly align the panel 105 within the frame.

As shown in Figure 2, the lower mount 104 may comprise a housing 110 slidably retaining a pivot member 135. The pivot member 135 may extend through a channel 112 through an upper surface 132 of the housing 110.

An Allen key 105 may engage a socket 111 through the upper surface 132 of the housing 110 to cause the pivot member 135 to slide along the channel 112 so as to thereby finely adjust the pivot point at the lower edge of the panel 105.

The lower mount 104 is generally recessed within a channel of the sill and therefore, as can be seen, the housing 110 may be generally small form factor, elongate and having a rectangular cross section so as to be suited for being recessed within the channel.

The upper mount 103 similarly comprises a housing 113. The housing 113 may connect to a mounting plate 120 similarly exposing a socket thereunderneath for offset adjustment of the pivot point of the upper edge of the panel 105, such as by using an Allen key 150.

As is also shown in Figure 2, in embodiments, an Allen key 150 may engage a distal end at the cylindrical portion 107 of the upper mount 103 so as to adjust the offset of the leaf 106 along the pivot axis of the upper pivot mount 103.

As such, with the pivot set 100, the user may adjust the pivot axes of both the upper and lower edges of the panel 105 and also adjust the offset of the upper leaf 106 along the pivot axis of the upper mount 103.

Figure 3 shows an underside view of the upper mount 103 showing the housing 113 which may engage the mounting plate 120. The mounting plate 120 may comprise a pair of fastener apertures for receipt of fasteners 144 therethrough.

The mounting plate 120 may further have an aperture for defining an upper tool engagement 151, such as for the Allen key 105, Phillips screwdriver or the like. Directional indicators may be embossed near the engagement 151 to indicate the effect of the direction of rotation.

The housing 113 and the plate 120 may define an upper elongate channel 122 along which an upper pivot member 123 is slidably retained. In the embodiment shown, the housing 113 may define a proximal stopper 124 which may extend beneath the mounting plate 122 to arrest the travel of the upper pivot member 123 within the channel 122 at one end.

Figure 6 shows a magnified underside view of the upper mount 103. As can be seen, the proximal stopper 124 may comprise a semicylindrical edge 125 which conforms with the correspondingly cylindrical profile of the upper pivot member 123.

Figure 4 shows the lower pivot mount 104 in further detail. In embodiments, the lower housing 110 may comprise an interlocking base plate 115 and cowl 114.

The cowl 114 may define the upper surface 132 and side edges of the housing 110, thereby providing a unitary covering being aesthetic and resistant to dust.

The upper surface 132 has the channel 112 at least part way therealong along which the lower pivot member 135 is able to slide. The lower pivot member 135 may be cylindrical with planar side cutaways 152 which engage against the corresponding adjacent linear inner side edges of the channel 112, thereby resisting rotation.

Figure 4 shows the lower tool engagement 111 similarly exposed through the upper surface 112 of the cowl 114, being conveniently located, especially for access using the Allen key 150 in the manner shown. Furthermore, the tool engagement 111 may be some distance away from the pivot point, such as 1 cm or more at the closest point so as to allow access away from the cylindrical section 107.

Figure 10 shows a cross-sectional side elevation view of the lower pivot mount 104.

The lower pivot mount 104 has the aforedescribed housing 110 which may be constituted of an upper cowl 114 and base plate 115.

The housing 104 may be made from plastic in embodiments.

The lower mount comprises a threaded shaft 116 rotatably engaged between the housing 110 and the pivot 135 to rotate about a threaded shaft rotational axis 153. In the embodiment shown, the threaded shaft rotational axis 153 is orthogonal to the pivot axis 154.

In embodiment shown, the base plate 115 and the cowl 114 may comprise protrusions which cooperate to define a proximal bearing 134 and a distal bearing 140 either side of the pivot member 135 within which the threaded shaft 116 is journaled.

The proximal bearing 134 may be open at a rear face of the housing 110. The threaded shaft 116 may have a length such that the proximal face thereof is recessed within the open bearing 134 or lies substantially flush therewith is shown in Figure 10.

The lower pivot mount 104 further comprises an adjustment member 144 rotatably engaged by the housing 110 to rotate about an adjustment member rotational axis 155.

The adjustment member rotational axis 155 is nonparallel with the threaded shaft rotational axis 153. Preferably, the adjustment member rotational axis 155 is more than 45° with respect to the threaded shaft rotational axis 153 such that the tool engagement exposed thereby 111 may be conveniently accessed away from the channel. In the preferred embodiment shown, the adjustment member rotational axis 155 is orthogonal with respect to the threaded shaft rotational axis 153 and parallel with the pivot axis 154.

Rotation of the adjustment member 144 causes the threaded shaft 116 to rotate which causes the pivot member 135 to slide with respect to the housing 110 along the threaded shaft rotational axis 153, thereby adjusting the pivot point at the lower edge of the panel 105.

The adjustment member 144 and the threaded shaft 116 may comprise bevelled gearing 142 therebetween. As such, the adjustment member 144 comprises conical bevel gearing 121 and the threaded shaft 116 comprises matching conical bevel gearing 130.

The threaded shaft 116 may comprise a threaded section which screws into a threaded transverse bore 138 of the pivot member 135.

Furthermore, the undersurface 139 of the pivot member 135 may be planar and slide along a corresponding planar surface of the base plate 115 so as to better withstand the weight of the panel 105.

The adjustment member 144 may define a cylindrical bearing 156 which is journaled within an aperture of an upper surface 132 of the cowl 114.

The cylindrical bearing 156 may coaxially define the recessed tool engagement 111.

The adjustment member 153 may be configured such that the upper surface of the cylindrical bearing 156 lies flush with the upper surface 132 of the cowl 114.

The adjustment member 144 may comprise a shaft 153 which rotated within bearing annulus 145 defined by the base plate 115. The bevel gearing 121 of the adjustment member 144 may locate between the cylindrical bearing 156 and the shaft 153.

The pivot member 135 may define a pivot pin 136 about which the cylindrical section 107 rotates about the pivot axis 154. A cap 137 may retain the cylindrical section 107 about the pivot pin 136.

The cowl 114 (of the base plate 115) may define a distal step having a horizontal surface 143. The step 143 may define at least one fastener aperture such that a fastener may be inserted perpendicularly through the horizontal surface 143 and base plate 115 thereunderneath into the still. The horizontal surface 143 may comprise two adjacent fastener apertures so as to allow for securement through the step 143 with a pair of fasteners.

Preferably, the housing 110 is retained to the sill only by these two readily accessible fasteners, thereby aiding installation.

Internal fasteners may extend up from the base plate 115 into the cowl 114 to retain the base plate 115 to the cowl 114.

Figure 9 shows a side elevation cross-sectional view of the upper pivot mount 103.

As can be seen, the upper pivot mount 103 similarly comprises a shaft 106 engaged between the housing 113 and an upper pivot member 147, the shaft being aligned along and orthogonal axis with respect to a pivot axis of the upper pivot member 147.

As is further illustrated in Figure 5, the upper housing 130 may be of unitary construction as opposed to the bifurcated construction of the lower housing 110 and defining the upper channel 149 therealong and a proximal bearing 154 and a distal bearing 155 within which the threaded shaft 146 is journaled, thereby supporting the threaded shaft 146 either side of the upper pivot member 147. The downward pull on the upper pivot member 147 by the weight of the panel 105 seats the shaft 146 within the bearings 154, 155.

The threaded shaft 146 may similarly comprise a threaded section 156 which screws into a correspondingly threaded transverse bore 157 of the upper pivot member 147.

The upper pivot mount 103 similarly comprises an adjustment member 156 geared to the threaded shaft 146 similarly preferably by way of bevel gearing 142. Similarly a nd preferably, the bevel gearing 142 may be configured such that the adjustment member 156 rotates along a rotational axis parallel to the pivot axis of the upper pivot member 147.

As such, rotation of the upper adjustment member 156 causes the upper shaft 146 to rotate, thereby causing the upper pivot member 147 to slide within the upper channel 149, thereby adjusting the position of the upper pivot point of the panel 105.

The upper adjustment member 156 may be shorter than that of the lower adjustment member 153 may similarly be configured such that the lower surface thereof lies substantially flush or slightly recess within an aperture of the mounting plate 120 thereby forming the tool engagement 151. The tool engagement 151 may simply comprise a recessed Allen key engagement.

The upper pivot member 147 may define a port 146 therein through which a pivot pin 158 is retained. The pivot pin 158 may be threaded into the port 146 such that rotation thereof may allow for vertical adjustment of up to approximately 1 cm.

Specifically, with reference to Figure 9, the pivot pin 136 of the upper pivot member 147 may define a tool engagement at a distal end thereof into which an Alan key or the like may be engaged to rotate the pivot pin 136 with respect to the pivot member 147. As such, rotation of the pivot pin 136 with respect to the pivot member 147 displaces the pivot pin 136 with respect to the pivot member along and elongate axis of the pivot pin 136 so as to allow also for vertical adjustment of a panel connected thereto.

The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the invention. However, it will be apparent to one skilled in the art that specific details are not required in order to practise the invention. Thus, the foregoing descriptions of specific embodiments of the invention are presented for purposes of illustration and description.
