Description
CAPPING STRIP
This invention relates to capping strips, used, for example, to conceal the joints of abutting panels laid side by side.
Trailer caravans generally comprise a body frame with internal panels, the panels being secured along their edges and the edges subsequently being concealed by capping strips which are fitted over the joints between the panels. Commonly, two-part capping strips, as described in U.K. Patent No. 1285356, are employed, having a base part secured to the panels, over a joint, and a cover strip which can be snapped into position over the base strip. Commonly, such a capping strip is of domed profile. The junction between transverse capping strips is, as a consequence, not of neat appearance, a gap being present at the junction of the strips. Whilst capping strips in which the cover strip is not of domed profile have been proposed, for example, the capping strip shown in Figure 1 of U.K.Patent No. 1285356, these would not always result in a very neat junction between transverse capping strips because, for example, abutting panels may not be accurately aligned with each other.
In accordance with the present invention there is provided a capping strip comprising a base strip for securement over a joint between two panels, and a cover strip for engagement on the base strip, the cover strip having a pair of generally upright side walls, and the base strip and the cover strip have inter-engaging means whereby the depth of engagement of the cover strip on the base strip may be varied.
Using a capping strip in accordance with the invention, a fitter may choose the depth of engagement of the cover strip on the base strip so that the junction between transverse capping strips is neat.
Preferably, the inter-engaging means whereby the
depth of engagement of the cover strip on the base strip
may be varied permits a variation of several mm, for
example, 1-5mm.
Preferably, the inter-engaging means for varying
the depth of engagement of the cover strip on the base
strip may be varied such that the depth of engagement
may differ along each lateral side of the capping strip.
Suitably, the means for varying the depth of
engagement of the cover strip on the base strip comprises
a plurality of teeth on one strip, engageable with a
plurality of teeth on the other strip, whereby the depth
of engagement may be varied in discrete steps.
Preferably, to ensure a neat finish, the teeth are such
that each step is less than lmm, suitably 0.4-0.9mm.
Each tooth preferably comprises a slant face and an
abutment face, the abutment face hindering removal of the
cover strip from the base strip, the arrangement being
such that there is engagement between respective slant
faces of the cover strip and base strip during the
operation of engaging the cover strip on the base strip,
and engagement between the abutment faces, to hinder
removal, once the cover strip is on.
Preferably, the base strip comprises a pair of
side walls extending from a connecting web, the outer
sides of the said side walls carrying teeth to co-operate with teeth carried on the inner sides of the side walls of the cover strip.
The side walls on the cover strip and/or the base strip may suitably have lead-in surfaces at a slant angle to the array of teeth, to aid engagement of the two parts.
Preferably, the cover strip comprises a pair of rails carried on its inside, whereby each said side wall of the base strip is located, on engagement of the cover strip on the base strip, between a rail and a side wall of the cover strip.
Suitably, the side walls of the cover strip are such that, in use, each side wall is substantially perpendicular to the panel over which it is located.
When the two panels are parallel to one another, a cover strip will preferably have side- walls which are substantially parallel to each other. When the panels are not parallel to each other, as at the apex of many trailer caravan ceilings, the cover strip will preferably have side walls which are appropriately angled to each other, whereby when the cover strip is engaged on the base strip each side wall of the cover strip will be substantially perpendicular to the respective panel.
Preferably, the cover strip and base strip are of a semi-rigid plastics material and are formed by extrusion.
The invention will now be further described, by way of example, with reference to the accompanying drawings in which:
Fig. 1 shows a capping strip suitable for screening the joint 2 between two panels 4, 6 at the apex of a trailer caravan ceiling;
Fig. 2 shows a capping strip suitable for screening the joint between two parallel panels; and
Fig. 3 shows a modified capping strip of the type shown in Fig. 1.
The capping strip of Fig 1 comprises a base strip 8 secured to panels 4, 6 and a cover strip 10 engaged on the base strip.
The base strip 8 comprises two side walls 12, 14 each extending perpendicularly from a connecting web 16.
The outer side of each side wall is formed with a plurality of teeth, each tooth having an abutment face and a slant face set at 600 to the abutment face. The web 16 has a pair of sloping surfaces 18, 20 which engage the panels 4, 6 and by means of which the base strip is secured to the panel. For example it-may be screwed or glued to the panels in these regions.
The cover strip comprises a pair of side walls 22, 24 connected by a web 26, the web being slightly concave. The outer surfaces of the side walls are not parallel to one another but are set at an angle of about 220 to each other. The angle of the panels 4, 6 to each other is about 1580 and it will be apparent that the outer surfaces of the side walls 22, 24 are perpendicular to the panels 4, 6. The inner surfaces of the side walls 22, 24 are formed with teeth of identical form to the teeth on the outer surfaces of the side walls 12, 14 of the base strip. At the free end of each side wall 22, 24, leading to the teeth, is a lead-in surface 25, inclined to the side walls 12, 14 of the base strip 8.
The capping strip is fitted by securing the base strip to the panels and then pressing the cover strip onto the base strip to the desired depth. Location of the side walls 12, 14 of the base strip 8 with the cover strip is assisted by the lead-in surfaces 25 and the rails 26, 28. During the securement operation slant faces of the teeth of the cover strip and base strip slide over each other and once the cover strip is on, respective abutment faces hinder removal. The capping strip is designed such that when the panels 4, 6 are inclined to each other at the correct angle, and their surfaces are smooth and clean, the cover strip will engage on the base strip at an intermediate depth of the various possible depths, with some but not all of the respective teeth of the two parts inter-engaged.In this way, if the set-up of the panels is not quite regular, or if their surfaces are not properly smooth, there will be scope for the cover strip to be engaged on the base strip at a greater than normal or lesser than normal depth, as required. The depth of the array of teeth on each respective side wall is 3mm in this embodiment, there being six teeth, each one 0.5mm in depth.
The parts are made of a semi-rigid plastics material, by extrusion. The cover strip and base strip are sufficiently flexible that the capping strip may be used with similar advantage when the panels are set at a somewhat different angle to each other, and when it is required to engage the cover strip on the base strip to a greater depth on one side than the other.
In the embodiment of Fig. 2 the panels 4,6 are parallel to each other and butt jointed. The outer surfaces of the side walls 22, 24 of the cover strip are parallel to each other, so that when the cover strip is engaged on the base strip, as shown, those outer surfaces are perpendicular to the panels 4, 6. Should the panels 4, 6 be parallel with each other but out of alignment, the cover strip can be engaged on the base strip to a greater depth on one side than on the other, the base strip and cover strip being sufficiently flexible to permit this.
The embodiment of Fig. 3. is similar to that of
Fig. 1. but the teeth extend further along the side walls of the cover strip, substantially along its entire length. The pitch of the teeth in this embodiment is 0.7mm.
All of the features disclosed in this specification may be combined in any combination, except combinations where at least some of such features are mutually exclusive.
The invention is not restricted to the details of the foregoing embodiment(s). The invention extends to any novel one, or any novel combination, of the features disclosed in this specification.
