Definitions

  • the present invention relates to a closure panel such as found for example in office furniture, in particular, as a sliding front panel or roller shutter panel of office cabinets but also kitchen cupboards and as found in heavier duty applications such as roller shutter doors of windows, doors and vehicle entrances.
  • the panel typically consists of a plurality of laterally adjacent slats, which are interconnected in a manner such as to allow relative movement between adjacent slats into and out of the plane of a panel in flat condition so that the panel may follow an arcuate track or be wound around a roller.
  • slatted panel In a so-called slatted panel, this is achieved merely by providing a plurality of elongate solid, rectangular section, slats adjacent to one another, one pair of opposed faces providing respective front and rear walls and the other pair providing respective side walls.
  • the front walls together define a front wall of the panel while the rear walls are secured together by a flexible substrate, which allows for flexure of the panel when guided around an arcuate track.
  • a flexible substrate which allows for flexure of the panel when guided around an arcuate track.
  • a plurality of laterally adjacent slats are interconnected in a manner such as to enable relative rotation between adjacent slats. This is typically by means either of a pivot, hinge, a sliding joint arrangement, a resilient interconnection member or other joint arrangement between respective longitudinal sides of adjacent slats.
  • a typical known arrangement of this type is shown in Figs. 1 and 1a.
  • a panel 50 comprises a plurality of slats 52, each having a front wall 54, a rear wall 56 and respective side walls 58, 60, one side wall 58 being profiled so as to provide an elongate part-circular socket 59 and the other side wall having protruding therefrom a rigid strip 61 terminating in an elongate hollow rib 62.
  • Rib 62 is slidable longitudinally into socket 59 and is then rotatable therein. Flexure of the panel is achievable solely by means of this relative rotation.
  • FIG. 2 shows a panel 70 comprising a plurality of hollow slats 72, 86, each having a front wall 74, a rear wall 76 and respective side walls, profiled as described below.
  • the hollow slats are strengthened by a web 78 extending between the front and rear walls 74 and 76 respectively.
  • Each slat 72, 86 of an adjacent pair of slats is secured one to the other by a flexible strip 71 secured to and extending between adjacent side walls 84 of adjacent slats at a position rearward of each front wall 74 and forward of each rear wall 76.
  • Side walls 84 are each curved so as to extend laterally inwardly from the front wall 74 to the rear wall 76 so that when the panel is in a flat condition as shown in Fig. 2, respective edges of the front walls 74 may abut one another to provide a continuous front surface of the panel, whereas, on flexure of the flexible strip 71, respective adjacent strips are capable of rotation relative to one another out of the plane defined by the abovementioned continuous front surface.
  • one slat of each adjacent pair thereof is provided with a side wall 80 opposite to side wall 84, which side wall 80 is profiled so as to provide an elongate part-circular socket 82, while the other slat 86 of each interconnected pair thereof is provided with a side wall 90, having protruding therefrom a rigid strip 92, terminating in an elongate hollow rib 88.
  • rib 92 is slideable longitudinally into socket 82 of an adjacent slat of an adjacent pair thereof and is then rotatable in socket 82.
  • Flexure of the panel is therefore achievable by means of the relative rotation between adjacent pairs of slats 74, 86 and by flexure of the strips 71 between each slat of a respective pair thereof.
  • the present invention addresses the problem of providing a simple panel construction which is sufficiently stiff for commercial use whilst providing sufficient flexibility for efficient sliding around an arcuate track or storage around a roller, which panel can be produced inexpensively and which may allow the provision of a separate profile or means for attachment of a handle to be dispensed with.
  • a panel for use as a flexible closure member capable of travel around an arcuate track or storage around a roller which panel comprises a plurality of elongate hollow slats each laterally adjacent to another, and a backing material comprising at least one flexible substrate secured to a face of each slat, the or each flexible substrate extending at least longitudinally of the panel and laterally of the slats from a region of a face of a first end slat at one longitudinal end of the panel to a region of a face of a second end slat at the other longitudinal end of the panel, so as to connect the slats to one another, each slat having an elongate front wall portion and an elongate rear wall portion opposite to and spaced apart from the front wall portion, which front and rear wall portions are interconnected by opposed, spaced apart, elongate side wall portions, respective front wall portions being capable of defining a front face of the panel and respective rear wall portions providing
  • the slats are preferably of extruded plastics material and are more preferably extruded from different respective plastics materials, one plastics material providing a body portion of the slat and the other a surface portion defining a front face of the front wall portion of each slat, so as to provide a visible "skin" surface of the panel.
  • a relatively inexpensive material can be employed for the body of the slat, while a more expensive but aesthetically more pleasing material may be used to provide a veneer on the front wall portion of each slat so that the view presented by the front of the panel may be particularly attractive and may, for example, be of an attractive colour or provide a metameric effect in which the panel changes colour with the point of viewing.
  • the slats may be a one-piece extruded plastics material optionally including therein decorative material, for example, coloured, especially silver, flakes.
  • the protrusions provided by respective side wall portions of the slats may be defined by regions of respective side wall portions which are generally convex while the recesses may be defined by correspondingly profiled regions of respective side wall portions which are generally concave. Generally convex regions of respective side wall portions cooperate with generally concave regions of respective side wall portions of adjacent slats.
  • each of the generally convex and generally concave regions of respective side wall portions of each slat is preferably defined by a respective generally central section of the side wall portion spaced from each of the front and rear wall portions of the slat and connected thereto by respective regions of the side wall portions defined by generally planar sections, at least the generally planar sections connecting the central section to the front wall portion each having an angular disposition relative to the front or rear wall portion such as to cooperate with a corresponding planar section of a side wall portion of an adjacent slat.
  • each generally planar section of each side wall portion which connects the generally central section to the front wall portion has an angular disposition generally perpendicular to the front wall portion.
  • each generally planar section of each side wall portion which connects the generally central section to the rear wall portion has an angular disposition generally perpendicular to the rear wall portion.
  • the region of one side wall portion of each slat which is generally convex and the region of the other side wall portion of each slat which is generally convex each extend substantially from the front to the rear wall portion.
  • each side wall portion may include a forward section providing one of a convex and a concave region and a rearward section providing the other of a convex and a concave region, respective adjacent side wall portions of adjacent slats being correspondingly profiled to allow interengagement of respective adjacent convex and concave regions with one another.
  • respective protrusions and correspondingly profiled recesses by respective side wall portions which have generally planar sections, a first section protruding (or receding) laterally from the front wall portion, a second section protruding (or receding) laterally from the rear wall portion and a third section extending between the above mentioned first and second sections, which third section is generally perpendicular to at least the front, and most preferably additionally, the rear wall portions.
  • one of the slats may be profiled so as to be provided with a longitudinal recess in the front wall portion thereof, which recess is capable of serving as a handle.
  • an aperture may be provided in the front wall portion through which a user may insert his fingers.
  • the backing material may be flexible substrate, preferable a one-piece flexible substrate, extending essentially over the entire panel.
  • a flexible substrate is preferable a fabric, more preferably a non-woven fabric.
  • the backing material comprises a plurality of flexible substrates, such as a plurality of tapes of plastics material.
  • the flexible substrates may be attached to the slats by means of an adhesive or by welding, for example, by thermal or vibration, especially ultrasonic, welding.
  • a panel embodying the invention may be adapted to allow its travel along an arcuate path, especially when the panel is to provide a side wall opening shutter.
  • the backing material is preferably a one-piece flexible substrate, especially a fabric.
  • a panel embodying the invention may be adapted for storage around a roller to provide a roller shutter assembly, for example of the balanced spring roller type disclosed in GB-A-2241727.
  • the backing material may then be conveniently provided by a plurality of tapes of plastics material extending longitudinally of the panel.
  • the backing material may be a textile material.
  • a continuous front face of the panel may be obtained when the panel is in the flat condition and secondly, efficient interengagement can be achieved when the panel is in the flat condition, thus providing the panel with a particularly high stiffness when in a flat condition.
  • the respective side wall portions may be easily separated from one another.
  • Fig. 3 shows a section of a panel, generally indicated as 1, comprising a plurality of elongate slats 2 each having a front wall 4, a rear wall 6 and respective side walls 8, 10.
  • the respective slats 2 are interconnected by a flexible substrate 9 secured to rear faces of the rear walls 6 of respective slats 2 so as to provide the panel 1.
  • the flexible substrate 9 is preferably of non-woven material, especially of bonded polypropylene fibers. It is preferably secured to the slats 2 by means of an adhesive, for example, a polyurethane.
  • the flexible substrate 9 may be a sheet of plastics material, such as polyvinyl chloride, polypropylene or a polyethylene based material, which may be secured to the slats 2 by a hot melt technique such as by welding, especially sonic welding.
  • each slat has a pair of opposed side walls 8, 10, side wall 8 providing an elongate protrusion defined by respective sections 12, 14, 16 and a side wall 10 providing an elongate recess defined by respective sections 18, 20 and 22.
  • the protrusion provided by side wall 8 is defined by respective first and second planar sections 12 and 14 respectively protruding laterally outwardly from front and rear walls 4 and 6.
  • These first and second sections 12 and 14 are interconnected by a third elongate planar section 16 generally perpendicular to front and rear walls 4 and 6.
  • each slat is defined by respective elongate first, second and third sections 18, 20, 22.
  • First and second sections 18 and 20 extend laterally inwardly of the slat from respective front and rear walls 4 and 6.
  • a third section 22 extends between the first and second sections 18 and 20 in a direction generally perpendicular to the front and rear walls 4 and 6 respectively.
  • this generally trapezoidal construction of slat provides a particularly high degree of stiffness to the panel when in the flat condition, there being a particularly efficient interengagement between the respective side walls 8 and 10 providing respective cooperative protrusions and recesses. This is to be seen especially clearly from Fig. 6.
  • the panel in the flat condition, is particularly rigid and stable.
  • the flexible substrate and the absence of any locking in tension allows easy flexure during travel along an arcuate track 40 (see Fig. 5). Indeed, it is not only possible merely to flex the panel (Fig. 7) but also to fold it, for example, for storage, so that respective adjacent slats can lie one above the other (Fig. 8).
  • the slat, generally indicated as 42 has respective front (44) and rear (45) walls interconnected by respective side walls, generally indicated as 46 and 48, one of which (46) has a convex region and the other of which (48) has a concave region defined respectively by convex and concave sections 50 and 52 spaced from each of the front and rear walls 44, 45 of the slat 42 and connected thereto by respective regions of the side walls defined by planar sections 54-57.
  • Each planar section 54 - 57 extends perpendicular to each of the front (44) and rear (46) walls.
  • each side wall includes a forward section providing one of a convex and a concave section and a rearward section providing the other of a convex and concave section.
  • such side walls may have a generally S-shaped, or inverted S-shaped, configuration.
  • a part of a panel the slats of which have side walls so profiled is shown in Fig. 10.
  • each side wall generally indicated as 30, 32 of the panel has a short planar section 23, 24, adjacent to and normal to each of the front and rear walls 26, 28 respectively and a generally S-shaped section therebetween.
  • the S-shaped section includes a forward part, adjacent to the front wall 26, defining a convex lateral projection 34 and a rearward part adjacent to the rear wall 28 defining a concave lateral recess 36, while the other, opposed side wall has a forward part defining a concave lateral recess 38 and a rearward part defining a convex lateral projection 40.
  • forward convex lateral projections 34 engage in corresponding forward concave lateral recesses 38
  • rearward convex lateral projections 40 engage in rearward concave lateral recesses 36, thus providing a panel which, in the flat condition, is particularly rigid and stable.
  • panels embodying the invention may be fitted between respective opposed upper and lower tracks of a cabinet so as to provide respective closure members as shown in Fig. 10.
  • the panel When the cabinet is in the open condition, the panel may be folded into respective storage chambers at respective sides of the cabinet after being pushed into respective side track portions 101.
  • a slat of a panel may have a front wall profiled so as to provide therein a recess.
  • Fig. 12 shows respective end sections, generally indicated as 60 of panels providing cooperating side opening shutters in which an end slat 62 of each respective panel section 60 has a front wall 64 profiled so as to provide thereon a recess 66 which can be used as a handle.
  • a panel embodying the invention may be adapted for storage around a roller to provide a vertically opening shutter.
