Description

Island system for roofs.

The present invention relates to a system of islands for roofs that can be suspended according to the preamble of the first claim.

US-A-3023861 exposes a construction to receive acoustic slabs on a grid That can be suspended. The square model is obtained by arranging of separate parallel main shoes joined together by cross shoes on the opposite longitudinal sides of the main shoe, thereby forming a model grid square in which acoustic slabs can be received. Every shoe includes a longitudinal vertical soul and two flanges horizontal longitudinals pointing in opposite directions from a lower part of the soul, the cross section of the footings therefore being provided in a T-shape. The slabs They are supported by horizontal longitudinal flanges. Every cross shoe comprises languages that extend away from both longitudinal end parts of the cross shoes in a longitudinal direction. Languages can be inserted to through vertical slits provided in the vertical soul of the main shoe The cross shoes are fixed to the shoes main through wedge elements which are aimed at across languages in a direction perpendicular to the direction length of the cross shoe after the tongue has been inserted through the vertical slits.

Different types of constructions, which they use the T-shaped shoes that constitutes the grid to receive the slabs are known by the experts in the technique.

For example, the document US-A-4525973 exposes a construction which largely resembles the construction described in the US-A-3023861, however without the tabs that go away from both sides longitudinal ends of the cross shoe in one direction longitudinal but in which the shoe flanges transverse comprise clamps which are coupled to each other when two cross shoes are inserted in directions opposite perpendicular to the main shoe through the vertical slit in the main shoe.

Other examples of constructions that form a grid composed of shoes to receive slabs for example can find in the documents EP-A1-1430271 and WO 98/05831 where different means have been described for fixing the cross shoes to the main shoes.

EP 0 516 330 A2 discloses a system of islands which is designed to cover only part of a ceiling and which is delimited by a frame to which at least a main shoe can be mounted reliably and can be disassemble.

However, none of the publications of previously mentioned patents expose an island system whose shoes can easily adapt to the length in place of installation. This is therefore an object of the present. invention.

This object is achieved with an island system for ceilings that can be suspended, according to the attached claim one.

Since the frame elements define now the grid limits, the grid dimensions are they can define regardless of roof dimensions at which can suspend the system. The elements of the frame create an island which can be suspended to cover partially or completely the ceiling to which it can be suspended no need for walls adjacent to the island system to roofs

The use of the fixing element which it is mounted on the shoe and which comprises a first element of union provided to couple the corresponding second element of joint in the frame element in an elastic joint, allows the mounting a shoe to the frame element using the elastic properties of the joining elements. Within the scope of the present invention an elastic joint designates a joint in the which the joining elements can flex some with respect to the others when a force is applied. This has the advantage that no tools are required to couple and undock the elements of union first and second, making the assembly and disassembly of the Easy, fast and reliable rooftop island system.

Since the fixing element of the The present invention is preferably made of one piece. separated, it can be built so that it is suitable for use it in conventional shoe uses such as those described in documents US-A- 3023861, US-A- 4525973, EP-A1-0430271 and WO 98/05831.

In a preferred embodiment of the invention, the roof island system is characterized because the first connecting element comprises a first element the which is elastically mounted to the fixing element allowing quick and easy coupling of the first element of joint in the second joint element, allowing the shoe be reliably mounted to the frame and maintain the assembly of the fixing element so that it can be removed.

In a preferred embodiment of this invention, the roof island system is characterized because the first connecting element is placed to fit so sliding the second corresponding connecting element. He sliding coupling of the first connecting element in the corresponding second connecting element allows to move one or both, the shoe and the frame fixed to the shoe, one in relation to the other, in one direction along the first vertical soul of the frame element, without having to disassemble them. Like a consequently the position of the shoe in the longitudinal direction of the frame element or the position of the frame element in relation to the shoe in the longitudinal direction of the element of the frame can be modified for example after it has been established the union and therefore the assembly is facilitated and improves the versatility of the grid construction.

In another preferred embodiment of this invention, the first connecting element extends in one direction vertical of the frame. Thus the first connecting element you can attach the second joint element when the extreme part of the shoe in the frame element making it, Therefore, easy to install.

In a more preferred embodiment of this invention the island system for roofs that can be suspend is characterized in that the frame element It is mainly C-shaped, because the first longitudinal side of the first vertical soul of the frame element extends to along an upper edge of the first vertical soul of the frame element and because the second joint element in the frame element comprises a trimmed edge provided in the first flange of the frame element profile, the edge edging comprising a part of the first flange of the profile the which is folded to extend along the first edge of the profile and towards the second vertical soul of at least one shoe on an inner face of the first flange of the profile facing the longitudinal hole of the C-shaped frame element, the first connecting element of the fixing element being received between the first profile flange and the edged edge on the frame element. This way the risk can be minimized of the involuntary disassembly of the first connecting element and the frame element shoe after coupling with the second connection element since the first connection element It is captive on the edged edge.

In a further preferred embodiment of this invention the island system for roofs that can be suspend is characterized in that the frame element it comprises a second flange of the profile that points away from a second lower longitudinal side of the first vertical soul opposite the first longitudinal side, the profile flanges first and second running mainly parallel, the second profile flange being provided to support the flanges length of the shoe and cooperate with the fixing element to exert a pinching action on the shoe in the direction of the height of it between the flanges of the profile first and second of the frame element. The C shape of the element of frame allows to receive the shoe between the flanges of the profile first and second which limits the possible movements of the shoe in the direction of the height of the frame element. The friction resulting from the pinching action improves stability of the grid, reinforces the construction of the grid and limits a joint movement of the shoe in the frame element around an axis of longitudinal rotation of the shoe. The pinching of the shoe between the flanges of the first and second profile also reinforces the coupling of the first connecting element in the second connecting element, thereby minimizing the risk of a involuntary removal of the first joint element and the shoe of the frame element after coupling with the second union element.

The at least one shoe preferably comprises a reinforced edge that runs longitudinally along from the top of the second vertical soul. The element of fixing is provided to be mounted on the top of the reinforced edge. More preferably the fixing element it comprises a second and a third elastic element which are provided to perform a pinching action in the direction transverse edge reinforced on opposite sides of the edge reinforced of the shoe to which the element of fixation. The presence of the second and third elastic elements guides the fixing element when it moves or slides on the reinforced edge to the required position and makes the element of fixing is mounted more reliably to the shoe without having to use any tool

The fixing element 5, 15 however it can also be fixed to the main shoe 3, 13, 4 sliding the upper face 35 over the reinforced edge 21, 22 until the rear face 34 rests on the terminal edge vertical 36, for example, when the second and third lips are fold along the horizontal folding line.

The upper face 35 of the fixing element 5, 15 is preferably placed adjacent to the upper edge of the second vertical soul 11, 12 of the main shoe 3, 13. The face upper 35 is preferably mounted parallel to the flanges first 7, 8 and second 17, 18 of shoe 3, 13, 4 and perpendicular to the second vertical soul 11.

The groove 33 of the fixing element 5, 15 is placed above the vertical terminal edge 36 of the shoe 3, 13, 4. The groove 33 also extends over part of the face rear 34 on the reinforced edge 21, 22. Inside the slot 33, parts that extend in height and in can be accommodated longitudinal direction from the reinforced edge 21, 22 or the second vertical soul 11, 12 of the shoe 3, 13, 4. The parts that are prolong for example can be the result of cutting or sawing the shoe 3, 13, 4, forming the vertical terminal edge 36, for Get the desired length. Receiving the extensions through of the groove 33, the mounting of the fixing element 5, 15 to the shoe 3, 13, 4 and therefore the grid construction remains unaffected and the length of the shoe 3, 13, 4 can be adapt at the site where the island is to be suspended from the ceiling. Therefore, shoes 3, 13, 4 can still be used with standardized dimensions and its length can be adapted in the site. Slot 33 can have any shape considered appropriate by the person skilled in the art, although preferably it is somewhat larger than the reinforced edge 21, 22.

The elastic elements second 31 and third 32 are provided to perform a pinch action in the direction cross section of the reinforced edge 21, 22 on opposite sides of the edge reinforced 21, 22. The clamping action exerted by the elements elastic second 31 and third 32 limits the movement of the shoe 3, 13, 4 in the transverse direction of the fixing element 5, 15 and prevents the articulation of the shoe 3, 13, 4 in the element of fixing 5, 15. The elastic elements second 31 and third 32 preferably they extend along the height of the edge reinforced 21, 22, the clamping action preferably extending in the direction of the reinforced edge width 21, 22, a configuration of this type causing friction and limited the movement of the shoe 3, 13, 4 in the fixing element 5, 15 in the height direction of the fixing element 5, 15. The elastic elements second 31 and third 32 however it also they can rest on the bottom of the reinforced edge 21, 22, the pinching action preferably extending in the direction of the height of the reinforced edge 21, 22 to cause friction which also limits the movement of the shoe 3, 13, 4 in the element fixing 5, 15 in the direction of the height of the element of fixation 5, 15. The elasticity of the second elastic elements and third 31, 32 allows the fixing element 5, 15 to be easily mounted on reinforced edge 21, 22 without use of tools. The first slit 30 has a width which preferably it is somewhat smaller than the width of the reinforced edge 21, 22 to which it is mounted causing the pinching action and the amount friction required to reliably mount the element fixing 5, 15 to the reinforced edge 21, 22.

When the elastic elements second 31 and third 32 are bent towards the rear face 34, the movement of the end part 6 of the shoe 3, 13, 4 in one direction longitudinally moving away from the rear face 34 is limited. When the second 31 and third 32 elastic elements are bent upward towards the upper face 35, the pinching action on the Reinforced edge height direction 21, 22 also limits the shoe movement 3, 13, 4 away from the rear face 3. 4.

The fixing element 5, 15 preferably does not extends substantially beyond the end part 6 in the direction of the length of the shoe 3, 13, 4 which is bounded by the vertical terminal edge 36. Instead the face posterior 34, preferably the upper part 46 of the face rear 34, rests on the vertical terminal edge 36 of the shoe 3, 13, 4 and thereby limit the movement of shoe 3, 13, 4 in the fixing element 5, 15.

In the mounted position of the fixing element 5, 15 the lower parts first 47 and second 48 of the face posterior 34 extend along the second vertical soul 11, 12 of shoe 3, 13, 4. The second slit 40 receives the edge vertical terminal 36, so that the width of the second slit 40 it has to be equal to or greater than the width of the second soul vertical 11, 12. Receiving the vertical terminal edge 36 in the inside the second slit 40 prevents the shoe 3, 13, 4 from being move in the transverse direction of the rear face 34 of the fixing element 5, 15. To further limit the lateral movement of the vertical terminal edge 36, the second slit 40 is preferably just big enough to allow reception of the vertical terminal edge 36. Position that the first 47 and second 48 lower parts of the face rear 34 are folded toward the front face 42 and extends below the reinforced edge 21, 22. The movement of the shoe 3, 13, 4 in the fixing element 5, 15 is therefore limited in The direction up.

Preferably a fixing element 5 is mounted on both opposite end parts 6 of the main shoe 3, 13. The cross shoes 4 attached to the frame element 10 generally will not comprise any fixing element or only a fixing element 15 which is mounted to the end part 6 attached to the frame element 10.

The assembly of the main shoes 3, 13 in the inside of the circumferential frame 2 is achieved because the end parts 6 of the main shoes 3, 13 with the elements fixing 5, 15 are received inside the elements of the C-shaped frame 10 so that the upper face 35 is adjacent to the first flange of profile 27. The assembly of the cross shoes 4 inside the circumferential frame 2 is achieved because the extreme part 6 comprising the element of fixing 15 is received inside the elements of the C-shaped frame 10 so that the upper face 35 is adjacent to the first flange of profile 27.

When the shoes 3, 13, 4 are inserted in the inside the frame element 10, preferably the first clamp element behind the edged edge 29 of the element of the frame 10. The first element is then received between the first flange of profile 27 and edged edge 29. The face rear 34 of the fixing element 5, 15 preferably rests on the first vertical soul 26. Since the edged edge 29 preferably runs along the entire length of the frame element 10, the first element can be moved to along the edged edge 29 while the shoe 3, 13, 4 remains inserted inside the frame element 10. This allows placing the shoe 3, 13, 4 on the frame element 10 after the shoe 3, 13, 4 has been inserted inside of the frame element 10 without having to remove it.

The second longitudinal flange 17, 18 together with the first longitudinal flange 7, 8 provides the shoe 3, 13, 4 with a larger base which rests on the second flange of the profile 28 compared to a single flange of the profile 7, 8 which provides to the shoe 3, 13, 4 an additional stability, reinforces the grid and prevents a first joint movement of the shoe 3, 13, 4 in the frame element 10 around a longitudinal axis of the shoe 3, 13, 4 a along the second vertical core 11, 12. The first articulation movement is avoided by the first longitudinal flange 7, 8 and second 17, 18 used in combination with the C-shaped frame element 10 and the upper face 35 of the fixing element 5, 15 having a certain width in the transverse direction of the shoe 3, 13, 4 since the clamping action resulting from the flanges of the first 27 and second 28 profile of the C-shaped frame element 10 presses on the part upper 35 of the fixing element 5, 15 or on the first longitudinal flange 7, 8 and second 17, 18 of the fixing element 5, 15 or the longitudinal flanges 7, 17, 8, 18 by its width preventing the shoe 3, 13, 4 perform the first articulation movement
lotion

The rear face 34, which have a certain width and a surface, and the width of the longitudinal flanges first 7, 8 and second 17, 18 prevent the shoe 3, 13, 4 from carrying out a second joint movement around an axis vertical perpendicular to the longitudinal direction of the shoe 3, 13, 4 since the longitudinal flanges 7, 8, 17, 18 and the face posterior 34 rely on the first vertical soul 26 of the element of the frame 10.

Since the movement of the shoe 3, 13, 4 in the fixing element 5, 15 is limited in direction longitudinal or vertical of the shoe 3, 13, 4 and avoid shoe joint 3, 13, 4 on the fixing element 5, 15, the junction between the shoe 3, 13, 4 and the frame element 10 It is tough and reliable.

To remove the shoe 3, 13, 4 from the element of the longitudinal frame 10, shoe 3, 13 articulates upwards or down along a horizontal axis of the shoe 3, 13, 4. The longitudinal flanges 7, 8, 17, 18 are pushed over the profile flanges first and second 28 until the first element is released from the edged edge 29 and the shoe 3, 13, 4 can be removed from the frame element 10. When pushed the longitudinal flanges 7, 8, 17, 18 over the flanges of the first and second profile 28, the first 27 profile flanges or second 28 can be pushed out to allow the first element more easily get off the edged edge 29.

The use of shoes 3, 13, 4, 14 and frame elements 10 makes the island system modular to ceilings 1. Therefore, the shoes 3, 13, 4, 14 and the elements of the frame 10 can be used for mounting a wide range of island systems for roofs 1 that have conformations, different shapes and dimensions.
