Abstract
A composite panel for forming sectional doors, comprising two sheet metal supports (4, 6) bounding a layer (8) of synthetic thermoinsulating material, in which the two supports are bent over along their edges to form the two parts of the articulation joint, the outer support (4) has one edge bent over towards the panel interior and extending in the direction of the panel thickness, and has its other edge bent over towards the panel interior and extending in the direction of the panel thickness, the inner support (6) has one edge forming a first continuous longitudinal rib (24), and has its other edge forming a second continuous longitudinal rib, the distance between the edge of said first continuous longitudinal rib (24) and the base of the second continuous longitudinal rib (28) of the adjacent panel is not less than a predetermined safety value when the two panels are coplanar.
Description
- This invention relates to a composite panel for forming sectional doors.
- Sectional doors are known consisting of a plurality of self-supporting panels hinged together and slidable on carriages along a pair of rails extending parallel to the edges of the aperture to be closed and parallel to the ceiling.
- Generally sectional door panels lie coplanar both when the door is completely open and when it is completely closed, but in passing from one to the other configuration they change their attitude and hence undergo one relative to the other a first rotation in one direction about the common hinging axis and a subsequent rotation in the opposite direction. When in their condition of maximum mutual inclination the angle formed between two adjacent panels can reach and even exceed 45°.
- A problem which panel manufacturers have always taken into account and have sought to solve is the risk of squashing the fingers of the user when manually operating the sliding door. In this respect, in moving adjacent panels for passage from their coplanar position to their angled position, the mutually hinged edges approach each other on the inside of the door, with evident danger of squashing any fingers which may be accidentally interposed between the two panels. In addition on the outside of the sliding door the mutually hinged edges withdraw from each other in passing from the position in which adjacent panels are coplanar to the position in which they are angled, and in the subsequent opposite passage they approach each other with the same risk to the user.
- To obviate this drawback various solutions have been proposed, all based essentially on a particular shape of the panel edge, the purpose of which is either to hinder finger entry between the two angled panels on the outside of the panel, or to ensure that the gap between the two angled panels on the inside of the door does not fall below a predetermined safety value.
- This general problem has been able to be solved in this manner, although its solution has given rise to further special problems such as the constructional complexity of the panel, its poor thermal insulation, the need to use specially constructed hinges, limited mutual angular travel between the panels, limited sealing power and life of the gaskets, and vibration under windy conditions.
- An object of the invention is to provide a panel for sectional doors which eliminates any risk of accidental squashing of the user's fingers, while at the same time overcoming all the other drawbacks which known arrangements jointly or separately present.
- This aim is reached according to the invention through a composite panel for forming sectional door as described in claim 1.
- The present invention is described in detail hereinafter with reference to the accompanying drawings, in which:
- Figure 1
- is a schematic perspective view of a sectional door formed from four panels according to the invention hinged together;
- Figure 2
- is an enlarged schematic detailed view showing the joint between two panels when mutually coplanar;
- Figure 3
- is a schematic view of the same detail as Figure 2 when the two panels are in the condition of maximum mutual angulation.
- As can be seen from the figures, the composite panel according to the invention for forming sectional doors is indicated overall by 2 and comprises two
supports outer support 4 andinner support 6. Between the two supports there is interposed alayer 8 of high-density polyurethane insulating material, which gives the panel solidity, high insulation and maximum practicality of use. - On the inside of said supports 4, 6 and hence embedded in the layer of polyurethane material there are also provided
steel plates 10, which as will be apparent hereinafter provide secure fixing for thehinges 12, for thecarriages 14 on which the door slides alongrails 16, and for other possible accessories with which the door is to be provided. - Each
panel 2 has two opposing edges hinged to the adjacent panels, and for this purpose the two supports 4 and 6 have their adges suitably bent over and embedded in the layer ofpolyurethane material 8 but without being in mutual contact. - Specifically, the
outer support 4 has an edge bent towards the interior of thepanel 2 to form afirst appendix 18 having its outer wall flat and coplanar with the support, and its inner wall curved concavely with its arc of curvature coincident with theaxis 20 of thehinges 12. - The opposite edge of the
outer support 4 is also bent towards the interior of thepanel 2 to form asecond appendix 22 having its outer wall curved convexly with its axis of curvature coincident with theaxis 20 of thehinges 12. - Both the curved walls of the
appendices layer 8 of polyurethane material. - That edge of the
inner support 6 corresponding to theappendix 18 is bent to form afirst rib 24, having a wall coplanar with the surface of the support and another wall which is more internal. - The
first appendix 18 and thefirst rib 24 together form the female element of the joint between mutually hinged adjacent panels, and house alongitudinal seal gasket 26 in the channel defined by them. - That edge of the
inner support 6 opposite that which forms therib 24 is bent to form asecond rib 28 positioned more inward than the preceding. - The
second appendix 22 and thesecond rib 28 together form the male element of the joint between mutually hinged adjacent panels and are provided at their top with anadhesive tape 30 cooperating with thegasket 26. - The bent-over edges of the
outer support 4 andinner support 6 are embedded in the layer ofpolyurethane material 8 without being in mutual contact, so eliminating the creation of any thermal bridge and hence ensuring optimum heat insulation for the panel. - The
hinges 12 are applied to thereinforcement plates 10 of thepanels 2 for their mutual hinging. The two constituent elements of each hinge are applied to theinner support 6 of two adjacent panels, hence making it possible to use hinges normally available commercially, they being mounted such that their hingingaxis 20 lies outside the panel. - The
carriages 14 on which the panels slide along thedoor guide rails 16 are also applied to saidreinforcement plates 10. During this axial sliding, the adjacent panels rotate one relative to the other, any accidental interposing of the fingers between adjacent edges being prevented for any mutual annular position of the panels because of the coincidence between thehinging axis 20 of thehinge 12 and the axis of curvature of the curved walls of theappendices - In addition, as the distance between the edge of the
rib 24 of each panel and the base of therib 28 of the adjacent panel is chosen so as not to be less than a predetermined safety value (for example 20 mm), even if the fingers are interposed between the two edges they run no risk of being squashed. - When the door is closed and the two adjacent panels are mutually coplanar (see Figure 2), the male element of the joint exerts a compressive force on the
gasket 26 present in the channel of the female element, so achieving a considerable sealing effect and life of the gasket, which is not subjected to any sliding stress. - When in this closed configuration the inner wall of the
rib 24 of each panel adheres to the outer wall of therib 28 of the adjacent panel, to again contribute to a satisfactory seal and also eliminating, by virtue of this support, any possibility of vibration under windy conditions. - Essentially, the panel according to the invention is considerably more advantageous than conventional panels for forming sectional doors, and in particular:
- it can be completely constructed by an automatic continuous production cycle, and hence at a high prodution rate, with production constancy, low cost, and the possibility of cutting the panels to size according to requirements,
- it has no thermal bridges and hence provides high heat insulation,
- it enables standard hinges easily obtainable commercially to be used,
- it offers virtually absolute safety against accidental squashing of the fingers, even for angles between adjacent panels exceeding 45°,
- it provides optimum sealing linked to the fact that the gaskets operate by compression and not by sliding, plus a very long gasket life,
- it has considerable mechanical strength and allows secure fitting of hinges, carriages and other accessories which may be required for door operation, and
- it does not vibrate, even if wind is present.
