Definitions

  • the present invention relates to a plastic profile which is angularly adjustable. More particularly, the invention provides a plastic profile which can either be set to a desired angle, or can be used as a door or window hinge. The profile is of particular utility in the construction of a shower stall.
  • a shower stall which includes, in one of its embodiments, a multi-functional profile enabling alternative rigid linear and variable angle connections, said profile having an open channel bracketed by at least two opposite outer sectors forming part of a circle, each of said sectors having a plurality of spaced-apart external ridges.
  • the spaces between these ridges which control the angle setting are typically up to 20 or 25 degrees.
  • Such a joint is made of two separate rigid extrusions, the angle being set on assembly on site by drilling and inserting screws through the mating profiles.
  • variable angle connector profile for connecting a plurality of enclosure panels, said profile comprising:
  • variable angle connector profile unit wherein the middle segment is made of flexible polyvinyl chloride (PVC) and the end segments are made of at least semi-rigid PVC.
  • PVC polyvinyl chloride
  • variable angle connector profile unit wherein the middle segment has an operating life in excess of 10,000 bend cycles and said profile unit forms a part of a door assembly, including its hinge.
  • the novel profile of the present invention serves in a new application which was not possible with previous designs. Since it was found that such a variable angle connector profile could be manufactured to have an operating life exceeding 10 000 bend cycles, it became possible to use the profile as a hinge for a door or window.
  • An important advantage of this type of hinge is that, due to continuity of material, there is no leakage path at any angle of use, and so no seal elements are required. Obviously, such inherent sealing is a significant advantage in the construction of a shower stall.
  • the three segments forming the connector profile unit of the present invention could be extruded separately and joined, when cold, by any suitable fabrication technique.
  • the use of coextrusion produces a superior joint at lower cost and is inherently completely leakproof.
  • each of said first and second end segments includes surfaces adapted to abut each other and to delimit the extent of movement of said end segments towards each other in a first sense of swivel from a linear alignment of 180° to a substantially perpendicular alignment of about 90°, while said segments are free to move in a second sense of swivel away from said surfaces to form a reflex angle therebetween, for accordian-like folding, storage and transport of a plurality of panels interconnected therewith.
  • US patent 5,729,867 discloses a flexible, hinged, load-bearing, integrally formed connector, including a first end segment, a flexible middle segment and a second end segment in which the middle segment includes a flexible plastic material and all three segments are co-formed as a single integral unit
  • US Patent 5,115,855 discloses a flat panel display end hinge in which the hinge means is three segments which are co-extruded as a single linear unit
  • neither of said references teaches or suggests a flexible hinged, load-bearing, integrally formed connector, comprising first and second end segments which include integral abutment and/or stop means adapted to limit the extent of rotation of said end segments towards each other from a linear alignment of about 180° to a substantially perpendicular alignment of about 90°.
  • a variable angle connector profile unit 10 for connecting two enclosure panels 12, 14.
  • a first end segment 16 has a first open channel 18, sized for receiving therein a first enclosure panel 12.
  • the first open channel 18 is sized to receive an unframed panel such as, for example, a sheet of safety glass.
  • the side recesses 20 can be utilized for a liquid-in-use sealant, while the end recess 22 can be used to retain a flexible seal strip (not shown).
  • the channel 18 could, of course, be made wider for accepting a framed panel.
  • the end segments 16, 24 are made of at least a semi-rigid plastic material.
  • a suitable plastic is rigid or semi-rigid polyvinyl chloride (PVC).
  • a flexible middle segment 26 is attached to the first end segment 16.
  • the middle segment 26 is shaped to allow it to bend inward up to 90 degrees, as will be seen in Fig. 6, and similarly, to bend outward, as will be seen in Fig. 7.
  • Middle segment 26 is made of a plastic material such as flexible PVC.
  • the center recess 28 is shaped to facilitate said bending and to avoid sharp section changes in order to eliminate stress concentrations during bending, as will be seen in Fig. 6.
  • a second end segment 24 is attached to middle segment 26.
  • the second open channel 29 shown is similar to the first open channel 18, and is sized to receive a second enclosure panel 14. If so required, the open channels 18, 29 can have different dimensions and configurations.
  • the three segments 16, 24, 26 are attached to each other by being co-extruded as a single integral unit. Covalent bonds are formed when the hot extrusions meet, resulting in adhesion lines which are as strong as the parent plastic. It goes without saying that such a bond is completely water-tight; of more significance is the high fatigue limit of the joint, which can be bent many times without danger of delamination.
  • variable angle connector profile units 30, 32, 34 are shown as used in a low-cost shower stall assembly 36, which is illustrated in folded condition for storage and transport.
  • the panel 38 forms the entrance door of the shower stall.
  • Use of the variable angle connector unit 30 will be described below with reference to Fig. 4.
  • the connector profile 32 is designed to allow a bend of 270 degrees between erection and folding of the shower stall. Folding of the shower stall assembly 36 brings substantial savings to transport and storage operations, and by avoiding disassembly of the panels 38, 40, 42, on-site erection time is saved.
  • the householder who may install the shower stall is not necessarily expert at assembly of such items, and receiving an enclosure in its pre-assembled configuration is of value in avoiding assembly errors and service calls.
  • Fig. 3 illustrates a variable angle connector profile unit 44 used in a multi-window assembly 46.
  • the windows 48 and 50 are held on angled intersecting planes in a rigid frame 52.
  • the vertical connector profile unit 44 takes up the required angle, acts as a hinge and connects the windows 48, 50 in a leak-proof manner.
  • the same profile 44 is also used horizontally.
  • the windows 48, 50 are openable using latches 53, due to the flexibility of connector profile unit 44.
  • Seen in Fig. 4 is a variable angle connector profile unit 30, similar to unit 10 shown in Fig. 1.
  • the middle segment 54 has an operating life in excess of 10,000 bend cycles.
  • the middle segment is made of flexible polypropylene, and end segments 56, 58 are made of at least semi-rigid polypropylene. This material has excellent resistance to bend cracking, and its low specific weight and high chemical resistance makes it suitable for use in a long-lasting profile, producable at low cost.
  • the profile unit 30 shown in Fig. 4 forms part of a door assembly 60, including its hinge.
  • the diagram shows a textured safety glass door used as part of a shower stall 62.
  • variable angle connector profile unit 64 further comprising retention means 66 for releasably holding unit 64 at a desired angle.
  • a first curved tongue 68 extends from the first end segment 70 and a second curved tongue 72 extends from the second end segment 74.
  • the two tongues 68, 72 are mutually proximate, and a plurality of fasteners 76 are inserted to retain any desired profile unit angle within the unit's range.
  • Fig. 6 illustrates the embodiment 10 shown in Fig. 1, bent inward to its limit, which in this example is 90 degrees. It will be noted that the recess 28 now forms center hole 78. The outer corner 80 also forms part of a circle, thus reducing stress concentration and contributing to the long life of the profile unit.
  • Fig. 7 illustrates the profile 10 bent outward 90 degrees. It will be noted that even further bending is possible. Re-examining Fig. 2, it will be seen that the profile units 32 are bent 180 degrees, or very close to that angle. Such severe bending is, however, usually carried out only once or twice when the enclosure is folded, and so there is no material fatigue problem.
  • Seen in Fig. 8 is a further embodiment 82 of the profile unit shown in Fig. 1.
  • the inner faces 84 of the open channels 86 are smooth.
  • the channels 86 are appropriate for use when the enclosure panel 88 to be inserted therein is to be attached by means of an adhesive instead of a sealant.
  • the center 90 of the flexible middle segment 92 has a thin section to reduce bending stresses.
