Description

By the coating of can mechanically interconnective panel forming

Technical field

The present invention relates to one by the coating of can mechanically interconnective panel forming.

Background technology

Body of wall, ceiling and coating ground, for example parquet floor, wooden floor or laminate flooring mainly are that the panel of rectangle is formed by coming it textural more.Panel has continuous groove and on each opposed long limit and minor face, has continuous tenon on a long limit and a minor face usually, and their shapes are matched with groove with combining.Through being connected of groove and tenon laying panel, wherein two adjacent rows' panel is provided with each other with staggering.

The known interlock that on groove and tenon, constitutes machinery, they make adjacent panel realize the kayser interlocking each other in floor covering.Can in the floor covering of laying, avoid thus owing to expand or contraction process formation seam.On the groove of panel and tenon, be configured with the blocking element of mutual coupling, its form is groove, space or convexity, is used to make the ground panel of connection not remain on bonding station with having glue.Panel is rotated along its long limit each other embed or clamping (geklickt) and then laterally mobile, make the interlocking bar interlocking on the minor face thus.In order to be easy to realize this point, can begin under situation, to use hammering slightly from opposed each minor face by means of the hammering piece.Dangerous at this, even when working carefully, also possibly cause damaging the ground panel.

Also there is solution, the minor face of mutual butt joint is interconnected through the tenon that on it is vertical, moves.Save thus and utilize the manual hammering of hammer.Tenon is preassembled, also saves thus afterwards to engage.This floor covering is the content of WO 2008/017301.Outstanding end at this tenon is manoeuvred in the groove of minor face, is used for making tenon partly to move to the groove of the correspondence of adjacent panel from a groove.Make the panel reciprocal interlocking in this way.

In any case, must make tenon keep having certain clearance and be installed in the opposed groove of corresponding accurate aligning of complementary panel in order to realize the mobility of tenon.This gap is preferably as much as possible little, and the seam region at two panels can not produce highly dislocation thus.But certain clearance is unescapable on principle.

Summary of the invention

The objective of the invention is, provide a kind ofly by coating, the especially floor covering can mechanically interconnective panel formed, wherein the dislocation of the height in seam region minimizes.

This purpose is achieved with a kind of coating with claim 1 characteristic.

Dependent claims relates to favourable improvement project of the present invention.

Set according to the panel of coating of the present invention and to be used for and to be suitable for the panel identical and mechanically connect with another.This connection is the Connection Element realization of groove and feather joint through the form on the complementary sides that is arranged on panel.Adjacent panel has a level respectively on its complementary each other side groove.In a groove tenon that can relatively move at least in part with respect to panel is set therein.Said tenon is embedded in the groove of adjacent panel when connecting adjacent panel and adjacent panel is ended with respect to vertical mobile phase interlocking.Said tenon has canned paragraph, and it is arranged in the groove of the fixing panel of tenon.

Said tenon has at least one convexity.This convexity is transverse to laying the plane, promptly giving prominence to towards the end face or the bottom surface direction of panel.Provide convexity thus, the outstanding zone that makes tenon in interlocking position is than wideer transverse to the well width of laying plane survey at boss.Therefore protruding that especially protrude in tenon and the corresponding to canned paragraph of well width.

Also also aim at the tenon that is arranged on the there thus for alignment slot, be noted that to make groove preferred water level land, promptly directed in laying the plane.But also can make groove and also make tenon thus with respect to lay plane inclination, promptly be provided with acutangulating.

Last groove jaw that said groove has different length respectively and following groove jaw, the zone that protrudes in shorter groove jaw than elongated slot jaw corresponding thus each other parallel interval opposed.The outstanding zone of said groove jaw is as the bearing surface of convexity.That is: said protruding the setting is used for, when contact with this outburst area of groove jaw transverse to the laying plane, move perpendicular to the laying plane of panel usually.In other words, make the protruding of tenon or outstanding zone not only at the width that is extruded back on the short transverse and is reduced to than the groove between each opposed outstanding zone of elongated slot jaw always, and simultaneously also on the laying plane, be that horizontal direction moves.The mobile of level realizes that so that is: convexity is the fixedly ingredient of tenon, and it has been bearing in the groove through the one of which end, but configuration is in this wise moved the other end of tenon on the laying in-plane.Therefore it is related that protruding and the interlocked segments of tenon are in effect, and said interlocked segments is owing to the motion of convexity can be moved towards the groove direction of adjacent panel.

Not only referring to the zone of extending between opposed each groove jaw on the meaning of the present invention as groove directly.It also refers to and long opposed that zone of groove jaw, because this space is also occupied by tenon.Said groove jaw, especially long groove jaw can be with its variable in distance of on groove depth, observing.Zone than the shorter groove jaw of protruding in of elongated slot jaw can be descended or biasing with respect to shorter groove jaw, strengthen distance thus with opposed groove jaw.But the position that descends also belongs to groove.

Said canned paragraph can be connected with interlocked segments through linkage section.Said linkage section according to the installation site preferably through being connected with canned paragraph at the hinge that on the seamed edge of its end face or panel bottom surface, is provided with.Said interlocked segments connects with linkage section through the hinge that on the opposed seamed edge in its diagonal angle, is provided with.The position of protruding projecting point is farthest mainly confirmed in the position of said hinge.

Said tenon is folding at least partly at initial position before connecting two panels, and wherein canned paragraph, linkage section and interlocked segments are come out from the plane transfer of canned paragraph around hinge each other in vertical direction.Complementally cut sth. askew with panel end face and bottom surface respectively in order to realize this folding side of the mutual sensing of canned paragraph, linkage section and interlocked segments that makes.

When connecting two adjacent panel through making protruding moving than the elongated slot jaw near panel.According to the installation site, convexity is pointed to up or down.Preferably, make protruding moving through contacting with the following groove jaw of the groove that holds interlocked segments of first panel.Moving both vertically causes horizontal movement, and convexity is slided along the following groove jaw of the groove that holds interlocked segments when horizontal movement.This causes that linkage section centers on two hinges and deflects in the horizontal plane of canned paragraph.Likewise, said interlocked segments also deflects in the horizontal plane of canned paragraph around protruding hinge.Said tenon launches from its folding state, as long as long groove side is approaching as far as possible far.When the dislocation of the height between the adjacent panel is minimum is this situation.Said interlocked segments is pressed in the groove of first panel through the grafting campaign of tenon.In order to make linkage section be easy to penetrate in the groove, can make the linkage section end face chamfering or the rounding that point to groove.

After the interlocked segments of tenon moves in the groove of adjacent panel, hinge between interlocked segments and the linkage section is positioned on the height of following groove jaw of the groove that holds interlocked segments.After connecting two adjacent panels, canned paragraph, linkage section and interlocked segments preferred water level land are directed.Because fixedly the following groove jaw of the groove of tenon only extends on the width of canned paragraph, the surface of the sensing panel bottom surface of linkage section and interlocked segments is placed on the following groove jaw of groove of the interlocked segments of holding tenon.

Except the above embodiments, can certainly imagine, each section of tenon is connected in the centre.In this case, the seamed edge towards the panel bottom surface of linkage section and interlocked segments forms convexity.Likewise, except canned paragraph, linkage section with the interlocked segments, tenon can also have other section.

In addition, it is contemplated that the embodiment of tenon, one of them protruding with definite mechanism connects.This mechanism realizes the interlocked segments of tenon is pressed in the groove of adjacent panel in the horizontal direction.At this as long as protruding and corresponding groove jaw contacts and move towards the direction of another groove side, with regard to relieving mechanism.

The concrete structure of said tenon is also relevant with laying method, especially can not lay with parallel, rectilinear motion when panel, but will be through the similar bending of oscillating motion the time.When oscillating motion, the outstanding zone of long groove side is observed for certain moment approaching to some extent on the length of groove.For example: in the 45 position, the groove side almost is positioned at end position on an end of groove, and the groove side has several centimetres distance at the other end.Especially in this case suitable is, perhaps is provided with the tenon that a plurality of spaces are provided with, and they do not hinder its motility.But also can be provided with a tenon, it is divided into the tenon section of the separate manipulation of ability through the slit transverse to the groove setting.

Said tenon section preferably has a common canned paragraph.This structure also can be called comb shape.This expansion structure is verified to be particularly advantageous, and second panel begins the vertical decline along groove at an end of groove, and the tenon section is snapped in the groove of first panel in time successively.Also can use in other the paving mode at each can separate manipulation the tenon section, if that is: panel is not mutual deflection, but when laying with parallel motion.

Said interlocked segments can have profile on the side of groove jaw above and/or under its sensing.Said linkage section can equally with interlocked segments have profile equally on one or two side.This profile can be a waveform for example, has the profile of single tooth or sawtooth.

The groove jaw of said panel can have the profile complementary with said profile.Can on one or two side of interlocked segments, be provided with the kayser parts equally, they insert interlocked segments in the groove of adjacent panel the time kayser in the respective voids of last groove jaw or time groove jaw.

Importantly, said interlocked segments cross-over connection is connected on the short groove jaw and adjacent slit than the elongated slot jaw another groove, is used for making the height dislocation of seam region of panel minimum.Said interlocked segments also must partly outstanding from the groove that holds it, promptly protrude in the short groove jaw of this groove.

In principle, said tenon can extend on the whole length of groove.In addition, groove vertically on can be provided with a plurality of tenons spaced reciprocally.They can have the interlocked segments of the separate manipulation of ability.Therefore also can make panel groove vertically on setting each other with staggering.It is contemplated that at this, canned paragraph is interconnected in the zone of groove, wherein said connection can be simultaneously as the distance piece between the tenon.

A panel is provided with the interlocking bar therein, and it is fixed on with being used to make adjacent panel tension load and lays the plane.Said interlocking bar also is used for connecting panel on the laying plane, and tenon will prevent, panel is relatively moved on short transverse each other.Because the interlocking bar of interlocking below adjacent panel is provided with the distance relatively large with respect to the panel end face, therefore additionally stipulate, make by the panel of interlocking bar mainly to be bearing on the support strip from following interlocking.It apart from the interlocking bar than be provided with biglyyer apart from groove.In other words, said groove is between support strip and interlocking bar.The function of said support strip is, reduces the distance of supporting-point and panel end face, and this is favourable for very thin-walled and soft material especially.Because support strip is near the panel end face, near the point-like effect seam, act on from the panel of following interlocking vertical force with short stroke import to adjacent, from the panel of following interlocking, when this interlocking bar through following laying is possible.Owing to be right after near the supporting point of force application, two height dislocation between the panel reduced under the situation of pulling load significantly.

Said tenon can be processed by same material generally.Correspondingly can make thin position as film hinge.Thicker position is used to bear the power transverse to laying plane effect.

The material that is used for tenon not only can be a timber, that is, can be timber or the material that contains wood fiber, the material of perhaps processing as base material by timber, and for example liquid wood, metal and metal alloy, for example spring steel can be considered composite material equally for tenon.Can use bimetallic or mixed plastic as with thermoplasticity or heat cured plastics plastics equally as base material.Said tenon also can be processed by fiber-reinforced plastic.Tenon is flexibly constituted.

Said tenon can be configured to before connecting, be under the preparatory tensioning.Make interlocked segments be pressed onto in the groove of adjacent panel and the additionally connection of fixing two panels through preparatory tensioning.

In addition, owing to elasticity or because for example use spring steel, the tenon with reset force is suitable for after opening connection, can said tenon being retracted or bounce back into initial position again.

The hinge of joint tongue section is preferably by processing with the tenon identical materials.Certainly can select other material to this equally, for example a kind of hot melt.Hot melt refers to solvation or hot glue, and they serve as the basis with polymer, resin or yellow wax for example and after cooling, also have flexibility.Basic design is on function, to be split up into the basis with flexible and stiff zone.The essential deformable material in hinged zone, and do not expect the interlocked segments distortion.Therefore to use than the littler flexible material in zone hinge or linkage section for interlocked segments.

Characteristics are in addition, can have two states.Said tenon occupies a stable position and a metastable position, makes tenon automatically return to stable state in the end masterpiece time spent from the meta position.Can be provided with bistable tenon equally, it is characterized in that, having two settling positions and the prerequisite from a position to each conversion of another position is the power effect.

Tenon with meta position is transferred to the meta position from settling position through BENDING PROCESS, on the contrary wherein the reset force from the meta position to settling position than reset force much little.This favourable power-stroke characteristic curve also can make full use of in the present invention.Crooked acting on simultaneously on the convexity that will move on the tenon.Said convexity is such to be moved far awayly, up to the tenon impact type spring into the meta position.This is an interlocking position.Also on sound, confirm interlocking position through click sound (on tenon that is made of metal or the protuberance that is being made of metal at least, occurring) like this.But, it also produces slight impact when reaching interlocking position.Tactile data and so-called click are rattled away the acoustic information of effect when laying and when admitting panel, be useful feedback also.Aspect material, the click effect of rattling away mainly produces in metal material.But also can pass through other flexible material, the realization of for example plastics on the principle.

Not restriction aspect the panel material is as long as it especially can reach required shape through smear metal processing.At this not only can be that timber or plastics are the panel of base material, and can be mineral material and composite material.The size of panel is a secondary cause.Said panel also can be big specification, for example the structure member plate of 600mmx1500mm.

Design of the present invention especially can be used on all floor systems, and surface coating wherein is set on matrix, and for example solid wood coating, laminate have the matrix of painted surface as surface coating, the cork on malthoid, the substrate etc.Said covering layer especially can be processed by having obducent facing paper, and it confirms the outward appearance of component plate.Therefore floor covering can be parquet floor, finished product parquet floor, wooden floor or laminate flooring.

Said floor covering especially also can be double floor or hollow floor, and wherein hollow space is positioned at below the coating, is below the panel, and hollow space is used for guide duct.Also advantageously, if can readmit each panel, this can very well realize through the present invention in this double floor.Because said tenon not only can be arranged on the minor face of panel, and can be arranged on the long limit, for example can each panel lifted again and then re-lay through sucker (Saugheber).
