Abstract

Up-stand sealing assembly (10) comprises of a flexible up-stand strip (11) having an upper boundary (12) and a lower boundary (13) an inner face (14) and an outer face (15). The inner face (14) has an upper region (16) and a lower region (17). Flexible adhesive tape (20) has an upper boundary (21) and a lower boundary (22), an inner face (23) and an outer face (24). Flexible adhesive tape liner (30) is releasable off the adhesive tape (20) in two or more strips (31, 32) to provide a tack free up-stand seal support and manipulation zone over one longitudinal portion of the adhesive tape. This facilitates an easy releasable alignment and engagement of a portion of the adhesive tape onto the perimeter side wall of a shower tray or bath, and the full engagement of the adhesive tape onto the wall.

Description

UP-STAND SEALING ASSEMBLY
The present invention relates to an up-stand sealing assembly adapted to be fixed onto a substantially vertical perimeter side wall of a shower tray or bath before final installation against a wall as a means to seal the joint between the shower tray or bath and an adjacent wall.
Relevant prior art relating retro-fit up-stand seals often details a pre-formed high tack adhesive tape bonded to a strip such as PVC or EPDM on one side with a releasable liner on the other.
Through the progressive removal of the adhesive tape release liner the adhesive tape (and strip) is pressingly adhered to the shower tray or bath perimeter side wall so that an upper section of strip forms an up-stand above a ledge typically sandwiched between a tile and wall.
Up-stands seals such as disclosed in EP1891877 and GB2387626A (being of the type described) can be difficult to install because of the high tack nature of the adhesive. If such up-stand seals are inadvertently misaligned on the side wall of a shower tray or bath during installation, it is virtually impossible to disengage the adhesive because the bond formed is not releasable without irrecoverable distortion in the strip and/or the adhesive rendering the seal un-usable thereafter. The greater the width of the bed of adhesive tape being applied to a fixture side wall the greater the potential problem.
Another problem with the above seals is that inadvertent finger contact with exposed high tack adhesive tapes during installation is disruptive and the resulting finger oil residue deposited on the adhesive tape diminishes the bond strength between the adhesive and side wall of the shower tray or bath. This is particularly problematic where the exposed adhesive tape lower region and boundary is inadvertently engaged by the fingers and obstructs the easy handling and manipulation of the up-stand seal during installation.
A problem with up-stand seals such as disclosed in GB2387626 when supplied in roll format, is the more viscous the non-setting adhesive tape used, the greater the problem of compression causing the adhesive tape to bleed out between non-overlapped tape liners and bond with the adjacent face whereby the roll internally bonds to itself. Up-stand seals such as disclosed in EP1891877 in roll format can have compression crease lines extending transversely across the adhesive bed. This problem is apparent in adhesive beds sandwiched between a non-stretchable release liner and a non-stretchable up-stand strip that in combination act as laminates on each side of the adhesive. Crease lines increase the risk of air pockets and water gateways developing at the interface between the adhesive and side wall of the shower tray or bath and consequently the risk of seal failure.
Up-stand seals that include a backing layer formed from elastomers, synthetic rubbers and rubber-like plastics such as described in EP1891877 may present problematic reactions with sealants and other waterproofing membranes. One such problem is plasticizer migration resulting in the discoloration of sealant between the ledge and adjacent bottom edge of the tile.
It is the object of this invention to limit or eliminate the aforementioned problems associated with prior art up-stand seals.
According to the present invention there is provided an up-stand sealing assembly adapted to be fixed onto a substantially vertical perimeter side wall of a shower tray or bath before final installation against a wall as a means to seal the joint between said shower tray or bath and adjacent wall, the up-stand sealing assembly comprising of a flexible longitudinal up-stand strip having an up-stand strip upper boundary and an up- stand strip lower boundary between which up-stand strip boundaries there extends an up- stand strip inner face and an up-stand strip outer face which up-stand strip inner face has an up-stand strip inner face upper region and an up-stand strip inner face lower region; and a flexible longitudinal adhesive tape having an adhesive tape upper boundary and an adhesive tape lower boundary between which adhesive tape boundaries there extends an adhesive tape inner face and an adhesive tape outer face; and a flexible longitudinal releasable adhesive tape liner; wherein on pre-installed face to face parallel longitudinal engagement, the adhesive tape outer face is bonded to the up-stand strip inner face lower region and the adhesive tape inner face is releasably engaged with the adhesive tape liner; characterized in that the adhesive tape liner is releasable off the adhesive tape in two or more separate longitudinal strips and the adhesive tape liner is aligned and releasably engaged with the adhesive tape in parallel longitudinal precut overlapping strips, whereby the adhesive tape liner provides a tack free up-stand seal support and manipulation zone over one longitudinal portion of the adhesive tape while facilitating an easy releasable alignment and engagement of another exposed portion of the adhesive tape onto the perimeter side wall of a shower tray or bath, and thereafter the full engagement of the adhesive tape onto same side wall.
In another embodiment, the adhesive tape liner is aligned and releasably engaged with the adhesive tape in parallel longitudinal precut or perforated strips that do not overlap.
Advantageously, the releasable tape liner material comprises an upper tape liner strip and lower tape liner strip.
Preferably, the adhesive tape is a tacky waterproof adhesive.
Conveniently, the adhesive is a butyl rubber compound.
Ideally, the up-stand strip is a stretchable compressible durable waterproof material that when engaged with the adhesive tape and adhesive tape release liner may be longitudinally rolled up to facilitate packaging and transport and later unrolled for installation.
Ideally after installation, the up-stand strip transversely extends above the adhesive tape to form a flexible durable up-stand seal above the shower tray or bath perimeter side wall to which the adhesive tape is bonded.

Figure 20 represents a perspective view of a variation of the up-stand sealing assembly as shown in Figure 10 with the exception that there are two releasable adhesive tape liners.
Referring firstly to Figures 1 , 2 and 3 of the drawings, the up-stand sealing assembly 10 comprises of an up-stand strip 1 1 , an adhesive tape 20 and a releasable adhesive tape liner material 30. The up-stand strip 1 1 is flexible and has an up-stand strip upper boundary 12 and an up-stand strip lower boundary 13 between which up-stand strip boundaries there extends an up-stand strip inner face 14 and an up-stand strip outer face
15. The up-stand strip inner face 14 further comprises of an up-stand strip inner face upper region 16 and an up-stand strip inner face lower region 17.
The adhesive tape 20 is flexible and has an adhesive tape upper boundary 21 and an adhesive tape lower boundary 22 between which adhesive tape boundaries there extends an adhesive tape inner face 23 and an adhesive tape outer face 24.
The releasable adhesive tape liner 30 is releasable from the adhesive tape. The releasable adhesive tape liner 30 comprises of an upper tape liner strip 31 and a lower tape liner strip 32.
The upper tape liner strip 31 has an upper tape liner strip upper boundary 33 and an upper tape liner strip lower boundary 34. The lower tape liner strip 32 has a lower tape liner strip upper boundary 35 and a lower tape liner strip lower boundary 36.
In pre-installation assembly the up-stand strip inner face lower region 17 longitudinally engages the adhesive tape outer face 24 and the adhesive tape liner 30 (and therefore 31 and 32) longitudinally releasable engages the adhesive tape inner face 23 respectively.
The pre-installed up-stand sealing assembly 10 may be wound in a roll as shown in Figure
1 for packing and carriage and can later be unwound on site for installation. The upper tape liner strip 31 overlaps and conceals the lower tape liner strip upper boundary 35 to prevent viscous adhesive tapes 20 in compression bleeding out between the upper tape liner 31 and lower tape liner 32. Less viscous adhesive tapes 20 may negate the necessity to overlap the upper and lower tape liners 31 and 32 respectively wherein they may be butt jointed.
It should be understood that the up-stand strip 1 1 is both stretchable and compressible and consequently not a cause of compression crease lines that may otherwise extend transversely across the adhesive tape 20 when the up-stand sealing assembly is wound in a roll as in Fig. 1.
Figure 4 details a sealing assembly 10 installed on a shower tray 40 wherein the adhesive tape upper boundary 21 is aligned with the external corner between the shower tray side wall 56 and shower tray ledge 57 (corner 41 in Fig 5). The upper part 53 of the up-stand strip 1 1 extending above the adhesive tape upper boundary 21 is sandwiched in the void 54 between the wall 50 and wall covering 51 in a bed of flexible sealant 55 to prevent water seepage between wall 50 and shower tray ledge 57.
The up-stand strip 1 1 is flexible and can transversely stretch to prevent leaks in the event of differential joint movement between the shower tray ledge 57 and wall structure 50.
Figure 8 details a perspective cut-away view of an extended up-stand sealing assembly similar to figure 2 but different in that a bond-breaker material 52 extends across the up- stand strip inner face 14.
As detailed in Figure 4, sealant 55 is applied into the joint between the wall covering 51 and shower tray ledge 57 and comes in contact with the up-stand strip inner face 14. Some ingredients in some sealants may react in contact with the up-stand strip inner face 14. In Figure 8 the isolating membrane material 52 serves as a barrier between the sealant 55 in Figure 4 and up-stand strip inner face 14 to prevent such a reaction.
In Figure 8 the isolating membrane material 52 may be a bond-breaker polythene tape with an adhesive face bonded to the up-stand strip inner face 14. Polythene has a low energy surface allowing the sealant 55 to disengage in the event of joint expansion thus reducing the chance of the sealant 55 splitting due the three side adhesion between the ledge 57 the up-stand strip inner face 14 and the bottom edge of the wall covering 51. It should be understood that isolating membrane material 52 is not limited to a polythene tape or the exact location detailed in Figure 8. The isolating membrane 52 may be extended (not shown) to cover a greater part or all the up-stand strip inner face upper region 16 to facilitate in a like manner the application of a sealant 55 or other alternative waterproofing membrane between the up-stand strip inner face upper region 16 and wall covering 51.
Referring to Figs. 5, 6 and 7, an installation method for this invention will now be described using a shower tray by way of example. Other possible fixtures include baths and worktops. Preparatory action requires the up-stand sealing assembly 10 be unrolled and the shower tray side wall surfaces to which the adhesive tape is being attached be cleaned with alcohol wipes or methylated spirits. The installer must complete the first and second fix procedures herein described on each side of the shower tray before commencing the next.
In a first-fix stage of the installation as illustrated by Figure 5, with fingers 45 under the sealing assembly for support shielded from adhesive tape inner face 23 by the lower tape liner strip 32, the upper tape liner strip 31 is peeled back to part expose the adhesive tape inner face 23, the adhesive tape upper boundary 21 is then aligned level with the uppermost outermost corner edge of the shower tray 41 and pressingly engaged thereon with the thumb 44 and progressively onward along corner edge 41 till this first side of the shower tray 40 is complete.
In the event of an initial misalignment of the sealing assembly 10 on the perimeter side wall 56 of said shower tray or bath 40, the upper tape liner strip 31 may be of such a limited width as to accommodate a release of the adhesive tape 20 off the perimeter side wall 56 and a subsequent realignment thereon.
In a second-fix stage of installation as illustrated by Figure 6, the hanging unattached sealing assembly 10 is raised approximately 90 degrees off the shower tray perimeter side wall 56 and the lower tape liner strip 32 progressively peeled back 100mm beyond the end of the perimeter side wall 56 to expose the remaining adhesive tape inner face 23. As illustrated in Figure 7, the exposed adhesive tape 20 is then permanently bonded to the adjacent perimeter side wall 56 by pressing downward from the top with the thumb 44 (or seam roller) expelling potential air pockets out in the process. The up-stand sealing assembly is installed onto the remaining perimeter side walls 56 in a similar fashion.
Referring to common features of the embodiments shown in Figures 9 to 20, the up-stand sealing assembly 1 10 comprises an up-stand strip 1 1 1 , a sealant/waterproofing isolating membrane 152, an adhesive tape 120 and where the up-stand sealing assembly 110 is not shown installed, a releasable adhesive tape liner material 130.
The up-stand strip 11 1 is stretchable and compressible and has an up-stand strip upper boundary 1 12 and an up-stand strip lower boundary 1 13 between which up-stand strip boundaries there extends an up-stand strip inner face 114 and an up-stand strip outer face 115. The up-stand strip inner face 114 further comprises of an up-stand strip inner face upper region 116 and an up-stand strip inner face lower region 1 17.
The adhesive tape 120 is flexible and has an adhesive tape upper boundary 121 and an adhesive tape lower boundary 122 between which adhesive tape boundaries there extends an adhesive tape inner face 123 and an adhesive tape outer face 124.
The isolating membrane 152 is flexible and stretchable and has an isolating membrane upper boundary 158 and an isolating membrane lower boundary 159. The isolating membrane 152 engages those parts of the up-stand sealing assembly 110 not desired to engage sealant 155 and other reactive sealing/waterproofing materials.
The releasable adhesive tape liner 130 is a protective film releasable from the adhesive tape 120.
In pre-installation assembly, the up-stand strip inner face 114 longitudinally engages the adhesive tape outer face 124, the isolating membrane 152 longitudinally engages the up- stand strip inner face 114 (Figures 10 and 1 1 ) or the adhesive tape inner face 123 (Figures 14 and 15) or both the up-stand strip inner face 114 and the adhesive tape inner face 123 (Figure 19) while the releasable adhesive tape liner 130 longitudinally engages the adhesive tape inner face 123. The pre-installation up-stand sealing assembly 110 may be wound in a roll as shown in Figures 9 and 14 for packing and carriage and can later be unwound on site for installation.
Figures 9 to 12 and 20 detail a up-stand sealing assembly 110 wherein the sealant isolating membrane 152 extends longitudinally on the up-stand strip inner face 114 substantially above, adjacent to and parallel with the adhesive tape upper boundary 121. To install, the releasable adhesive tape liner 130 is progressively back peeled to expose the adhesive tape inside face 123. The adhesive tape upper boundary 121 is then aligned level with the ledge 157 and the exposed adhesive tape inside face 123 below is pressed onto the perimeter side wall 156 leaving the upper part of the up-stand strip 153 and isolating membrane 152 to form an up-stand above the ledge 157. The sealant isolating membrane 152 prevents the sealant 155 between the ledge 157 and wall covering 151 making direct contact with the up-stand strip 1 11.
Figures 13 to 18, detail a sealant isolating membrane 152 extending longitudinally on the adhesive tape inner face 123, below, adjacent to and parallel with the adhesive tape upper boundary 121. To install, the releasable adhesive tape liner 130 is progressively back peeled to expose the adhesive tape inside face 123 and isolating membrane 152. The isolating membrane lower boundary 159 is then aligned level with the ledge 157 and the exposed adhesive tape inside face 123 below is pressed onto the perimeter side wall 156 leaving the upper part of the up-stand strip 153, the isolating membrane 152 and an adjacently sandwiched part of the adhesive tape 120 to form an up-stand above the ledge 157. The sealant isolating membrane 152 prevents the sealant 155 making contact with the up-stand strip 1 11.
In Figures 13 to 18 the adhesive tape 120 is also employed as a backing material behind the isolating membrane 152 to limit the volume of sealant 155 applied into the joint between the ledge 157 and wall covering 151 as highlighted in Figures 16 and 18.
Figures 17 to 18 detail a sealing assembly wherein the up-stand strip upper boundary 1 12 and lower boundary 1 13 extends only marginally outside the adhesive tape upper boundary 121 and lower boundary 122 respectively, to facilitate the adhesion of small mosaic tiles to the wall 150 and accommodate other circumstances where a low up-stand is preferred. In this embodiment the adhesive tape outer face 124 engages both the up- stand strip upper region 116 and up-stand strip lower region 1 17.
Figure 19 details a sealant isolating membrane 152 extending longitudinally both below and above and parallel with the adhesive tape upper boundary 121. The sealant isolating membrane 152 engages both the up-stand strip inner face 114 and the adhesive tape inner face 123. The up-stand sealing assembly is installed as explained in Figure 16.
Figure 20 represents a perspective view of the up-stand sealing assembly as explained in Figure 10 with the exception that there are two releasable adhesive tape liners. The upper tape liner strip 131 overlaps and conceals the lower tape liner strip upper boundary 135 to prevent viscous adhesive tapes 120 in compression bleeding out between the upper tape liner 131 and lower tape liner 132.
The removal of the upper release liner 131 accommodates hanging the sealing assembly 10 in position on the perimeter side wall 156 prior to removal of the lower release liner 132 which accommodates a full engagement of the adhesive tape inner face 123 with the perimeter side wall 156.
As detailed in Figures 12, 16, and 18, sealant 155 being pressure applied into the joint between the wall covering 151 and shower tray ledge 157 is forced against the up-stand sealing assembly 110. Without the isolating membrane 152 in position, this sealant 155 would make direct contact with the up-stand sealing assembly 110. Some sealants react on contact with rubber like elastomeric and synthetic materials. The isolating membrane 152 is strategically located on the up-stand sealing assembly 1 10 to oppose this sealant joint and act as a barrier between the sealant 155 and up-stand sealing assembly 1 10 to prevent such reaction.
The isolating membrane 152 may be a polythene tape with an adhesive face bonded to the up-stand strip inner face 1 14 and/or adhesive tape inner face 123. Where the adhesive tape 120 extends up over the ledge 157, the isolating membrane 152 also acts a bond-breaker to prevent debris sticking to the adhesive tape inner face 123 during the installation of the up-stand sealing assembly 110 and the subsequent installation of the wall covering 151. The bond-breaker properties of the isolating membrane 153 also accommodate slippage of the sealant 155 off the up-stand sealing assembly 1 10 in the event of joint expansion between ledge 157 and wall covering 151.
It should be understood that isolating membrane 152 is not limited to a polythene tape or the exact location detailed herein. The isolating membrane 152 may be extended (not shown) to cover a greater part or the entire up-stand strip inner face upper region 116.
It will of course be understood that the invention is not limited to the specific details described herein, which are given by way of example only, and that various modifications and alterations are possible within the scope of the invention as defined in the appended claims.
