Description

Floor and neck fixed system

The present invention relates to the locking system on a kind of mechanical connection floor (floorboard) and floor with this locking system.

Technical field

The present invention is specially adapted to the floor that wood materials is made, and under normal circumstances, described wood materials floor has reel and mechanically connected.Prior art that will be described below and purpose of the present invention and characteristic are especially being grown limit and minor face by rectangle veneer mosaic pavement plate mechanically coupled together at the application in this field.The present invention is specially adapted to floating floor, just the ground panel that can move with respect to substrate.Yet should be emphasized that, the present invention also is applicable to existing all types hard place panel (hard floor), and for example single wooden ground panel, the wooden ground panel with foliated core or plywood core, ground panel, thin layer with facing plate surface and wood fiber core laminate goods ground panel, have the ground panel of plastic core or similar core.What the present invention can certainly be used to other type can be by the mach floor of cutting tool, for example subfloor of veneer or shaving board.Even be not preferred, the floor also can be fixed in the substrate after the installation.

Background technology

Mainly due to laying characteristic, bonding strength and the quality of connection of its brilliance, mechanical connection has accounted for the very big market share at short notice.Even floor among the patent documentation WO 9426999 of more detailed introduction and trade mark are called Alloc hereinafter The floor compare with traditional sticker floor and have very big advantage, yet also wish it is further improved.

Mechanical connection system is not only to the connection on laminate floor but also all very convenient to being connected of floorboards of wood and composite floor.This floor can comprise a large amount of different materials at surface, core and dorsal part.As described below, these materials also can be contained in the different elements of connected system, for example bar (strip), locking member and slip feather (tongue).For example patent documentation WO 9426999 or WO 9747834 have introduced the scheme of a kind of compound (integrated strip), this scheme provides a kind of level to connect, a kind of slip feather connected vertically that provides also is provided, yet when forming mechanical connection,, cause the cost problem that causes by material because flooring material is carried out machine.

In order to realize best-of-breed functionality, for example 15 millimeters thick parquets should have the bar that width is approximately equal to the ground plate thickness, just 15 millimeters.Utilize about 3 millimeters slip feather, the quantity of waste approximately is 18 millimeters.The normal width on floor approximately is 200 millimeters, therefore approximately wastes 9% material.Usually, if expensive material manufacturing is selected on the floor for use, if if they are thick or their forms are little, the cost that waste of material causes is very big usually, thereby the connection linear meter(lin.m.) on every square metre of floor will be very big.

Certainly, if that use the aluminum strip form made respectively and just be fixed on bar on the floor in factory, the quantity of waste of material can be reduced.Compare in addition with by machine and by the bar that core is formed, aluminum strip can cause better and cheaper connected system.Yet aluminum strip has following defective, promptly needs considerable investment, must carry out a large amount of reconstructions so that transform traditional production line to factory, thereby produces the floor with this mechanical connection system.In the prior art, the advantage of aluminum strip is the initial specification that need not to change the floor.

When relating to when flooring material being carried out bar that machine produces, situation is opposite.Thereby the specification on floor must be adjusted, and forms bar and slip feather thereby have enough materials.For the laminate floor, often need to change the width of the facing paper that uses.All these adjustment and variation also require production equipment is carried out costly transformation and huge product adaptation (product adaptation).

Except the relevant problem of above-mentioned and undesirable waste of material, cost of production and product adaptation, bar also has following shortcoming, and is just very responsive to the infringement between transportation and installation period.

Generally speaking, keep the mechanical connection of existing superperformance to have very big demand simultaneously to a kind of low cost is provided, described superperformance is meant laying, mentions (taking up), quality of connection and intensity.Utilize prior art, can not obtain the low-cost floor that does not reduce intensity simultaneously again and/or lay function.An object of the present invention is to propose a kind of technical scheme, it can reduce cost, and keeps intensity and performance simultaneously.

The present invention originates from known floor, described floor has core, leading flank, trailing flank and relative adjoining edge part, one of them adjoining edge partly is formed the slip feather groove, this slip feather groove is determined by upper and lower antelabium, and has a bottom, another adjoining edge partly is formed slip feather, and described slip feather has to top in its free outer end.The slip feather groove has the bottom cutting portion shape of a band opening, an inside and interior locking surface.At least the lower lip part forms with the floor core is whole, slip feather has a locking surface, when two similar floor machineries link to each other, this locking surface cooperatively interacts with the interior locking surface of slip feather groove on the floor, thereby their leading flank and meets on vertical connection plane (VP) on same surface plane (HP).Patent documentation WO 9627721, DE-A-1212275 and JP3169967 have introduced this technology, will describe in detail to this hereinafter.

Yet will be introduced as background technology of the present invention before this, about the general technology of the locking system on floor and mechanical connection floor.

Prior art is introduced

In order to understand and to introduce the present invention and relevant the present invention knowledge of problem behind, hereinafter introduce the basic structure and the function on floor among patent documentation WO 9426999 and the WO 9966151 in conjunction with Fig. 1～10.At applying portion, hereinafter the introduction to prior art also is applicable to described hereinafter embodiments of the invention.

Fig. 3 a and 3b are respectively the top and bottom perspective views that shows floor 1 among the patent documentation WO 9426999.Floor 1 is a rectangle, has upper side 2, bottom side 3, two relative long limit and two relative short edges that form adjoining

edge part

5a and 5b that form adjoining

edge part

4a and 4b.

The adjoining edge part 4a on long limit and the adjoining edge part 5a and the 5b of 4b and minor face can mechanically be linked together, need not in Fig. 1 c, to use glue on the direction shown in the arrow D, thereby connecting plane VP (shown in 2c) contact (meet), thereby be laid state at them, the upside that makes them is in a common surface plane HP (shown in Fig. 2 c).

In the embodiment shown, just in the example among the patent documentation WO 9426999 (shown in Fig. 1～3), floor 1 has factory's mounting plane bar 6, and it extends along whole long limit 4a, is made by flexible elasticity aluminium sheet for described 6.Bar 6 stretches out, and exceeds at adjoining edge part 4a and connects plane VP.According to illustrated embodiment, bar 6 can be by mechanically attached on the floor, or adopts glue or alternate manner to make it attached on the floor.As described in the document, the composition material as can be attached the bar on the floor in factory also can use other strip material, for example some other sheet metal, aluminium or plastics.As described in the patent documentation WO 9426999 and as described in the WO9966151 and shown in, for example by the core on machine floor 1 suitably, bar 6 can with floor 1 whole formation.

The present invention is applicable to such floor, and just bar or at least a portion bar and core integrally form, and the invention solves the specific question in connection, dismounting and the production on this floor.But the floor core need not preferably by same material manufacturing.Yet bar always forms with the ground slab integral, and just it should be formed on the floor or in factory and be mounted.

In the known embodiment that meets above-mentioned patent documentation WO 9426999 and WO 9966151, the width of bar 6 approximately is 30 millimeters, and thickness approximately is 0.5 millimeter.

Similarly but short bar 6 ' is along the floor that a minor face 5a of 1 is set up.A part is projected into the locking member 8 that extends along whole 6 that has that the bar 6 that connects outside the VP of plane is formed.Locking member 8 has in its underpart in the face of the fixed surface 10 of the operable locks that connects plane VP, highly for example is 0.5 millimeter.When laying, this locking surface 10 cooperatively interacts with lock slots 14, and this lock slots 14 is fabricated on the bottom side 3 of the adjoining edge part 4b on the long relatively limit on floor 1 '.Bar 6 ' along minor face is equipped with a corresponding locking member 8 ', has corresponding lock slots 14 ' on the adjoining edge part 5b of relative short edge.Lock slots 14,14 ' leaves the edge that connects plane VP and is formed for deciding surface 10 ' with the fixed surface of operable locks 10 operable locks that cooperatively interact of locking member.

In order to go up long limit of mechanical connection and minor face in vertical direction (the direction D1 among Fig. 1 c), floor 1 is formed with the recessed portion or the slip feather groove 16 of a lateral open along an one long limit (adjoining edge part 4a) and an one minor face (adjoining edge part 5a).The upper lip that is connected

marginal portion

4a, 5a at this slip feather groove of upside limits, and limits at downside quilt bar 6,6 ' separately.On opposite adjoining

edge part

4b, 5b, has the part of being recessed on 18, its quilt and recessed portion or slip feather groove 16 (locking slip feather 20 qualifications that embedding Fig. 2 a) cooperatively interacts.

Fig. 1 a～1c is presented at last two such floors of ground U 1,1 ' two

long limit

4a, 4b how by downward-sloping and around rotating and can be connected to one another at together near surface plane HP and the center C that connects crosspoint between the VP of plane, and the floor is maintained simultaneously contacts with each other.

Fig. 2 a～2c display floor 1,1 '

minor face

5a, 5b are joined together by quick interlock (snap action).

Long limit

4a, 4b can utilize two kinds of methods to be joined together, and after laying the first row floor, after

long limit

4a, 4b be connected, the connection of

minor face

5a, 5b was mainly undertaken by quick-snap.

Shown in Fig. 1 a～1c, when a new floor 1 ' and the floor 1 that has been laid along their long leg divide 4a, when 4b is combined, as shown in Figure 1a, the long leg on the floor 1 that the long leg on new floor 1 ' divides 4b to be pressed towards to be laid divides 4a, thereby locking slip feather 20 inserts recessed portion or slip feather grooves 16.Shown in Fig. 1 b, the downward-sloping then U earthward in floor 1 ' moves.Locking slip feather 20 enters recessed portion or slip feather groove 16 fully, and simultaneously, the locking member 8 of bar 6 sticks in the groove 14.During downward-sloping moving, working in the top 9 of locking member 8, is used for new floor 1 ' is directed to the floor 1 that has been laid.

At the link position shown in Fig. 1 c, floor 1,1 ' is locked at D1 and D2 both direction upper edge their

long limit

4a and 4b, but floor 1,1 ' can move relative to each other in vertical (D3 direction just) along long limit.

How Fig. 2 a～2c shows by new floor 1 ' is essentially horizontally moved towards the floor 1 that has been laid and floor 1,1 '

minor face

5a and 5b can be linked together on D1 and D2 both direction.This connection has normally been carried out after the long limit on above-mentioned floor 1 ' has been connected, shown in Fig. 1 a～1c, in an adjacent rows by tilting to connect to the floor that has been laid 1 to interior.In first step shown in Fig. 2 a, the inclination surface of recessed portion 16 and locking slip feather 20 cooperatively interact, thereby as the direct result of

minor face

5a, 5b combination, force bar 6 ' downwards.At final access phase, when locking member 8 ' enters in the lock slots 14 ', upwards engaging of bar 6 ', thus the operating surface 10,10 ' on locking member 8 ' and the lock slots 14 ' is engaged with each other.

Operate by repeating shown in Fig. 1 a～1c and Fig. 2 a～2c, whole floor can be laid along all adjoining edge, and need not glue.Therefore the prior art floor of the above-mentioned type can mechanically be connected, at first make long limit downward-sloping mobile, move horizontally along the long limit (direction D3) on the floor 1 of having laid by making new floor 1 ', after long limit is locked, make minor face downward-sloping mobile, be fastened togather then.When joint was not compromised, floor 1,1 ' can be dismantled conversely, and then laid.The part of these laying technologies also is suitable for the present invention.

In order to reach best-of-breed functionality, allow to lay easily and dismounting once more, after being connected, the floor of prior art should can be in this state along its long limit, just minimum gap occurs between the operational lock surface 10 ' of the operational lock of locking member surface 10 and lock slots 14.Yet actual butt joint place between the floor is not needing the gap near on the connection plane VP of floor upper side (surface plane HP just).In this position, a floor must be pressed against on another floor.Introduced this gap among the patent documentation WO9426999 in more detail.When pressed each other on the long limit on adjacency floor, the gap between the operational lock surface 10,10 ' was 0.01～0.05 millimeter.This gap is convenient to locking member 8 and is entered lock slots 14, equally also is convenient to locking member 8 and leaves lock slots 14.Yet as mentioned above, the junction between the floor does not need the gap, this this position, surface plane HP be connected plane VP and on the upper surface on floor, intersect.

Connected system is guaranteed to move along fillet in latched position after connecting any limit, thereby can adopt the multiple mode that three basic skills are carried out modification to lay:

Long limit is tilted, make the minor face engaging;

Long checkpost is closed, make the minor face engaging

Minor face is tilted, two floors are inclined upwardly, new floor is moved along the minor face on the floor that has been laid, make two floors downward-sloping at last.

The most frequently used and safest method is at first to make long limit downward-sloping, and the floor is locked to each other together.Under lock-out state, the minor face to the 3rd floor moves then, thereby minor face can engage.Also can engage with another floor along just laying on one side along long limit or minor face.Move at lock-out state then, till opposite side and the 3rd floor are fastened togather.These two kinds of methods require engaging at least on one side.Yet also can need not quick-snap and lay.The third method is that the minor face on first floor at first tilts to the minor face on introversive second floor, and the long limit on this second floor links together with the 3rd floor.After connecting, first floor and second floor are inclined upwardly a little.Move along its minor face with being inclined upwardly on first floor, and till the last adjoining edge on the first and the 3rd floor contacted with each other, after this, two floors tilted downwards with connecting.

Be approximately the floor of the about 0.6 millimeter aluminum strip of 7 millimeters laminate floor and thickness for thickness, for above-mentioned floor and its locking system are in great demand very much on market.Equally, it also is very successful that floor among the patent documentation WO 9966151 shown in Fig. 4 a and the 4b is changed, yet have been found that, this technology is not specially adapted to the floor, the particularly parquet that is formed by a large amount of wood materials or gluing laminated wood material of being made by the wood fiber sill.The reason that this known technology is not suitable for this type products is exactly to have the slip feather groove of the necessary degree of depth because machine is carried out in the marginal portion with formation, thereby causes that lot of materials is wasted.

Shown in Fig. 5 a and 5b, british patent document GB-A-1430423 has introduced a kind of known mechanical locking system that is used for the floor.This system is that a kind of slip feather-groove connects, and is equipped with an extra hook that keeps on the flange that extends on slip feather groove one side, is formed with corresponding maintenance ridge (holding ridge) at the slip feather upside.This system requirements is equipped with the flange of hook to have considerable elasticity, not destroying under the adjoining edge situation on floor, can not dismantle.Tighter assembling makes makes difficulty, and the geometry of connection causes the lot of materials waste.

Patent documentation WO 9747834 has introduced a kind of floor with different mechanical locking systems.This locking system that is used for locking long limit, floor (in Fig. 2～4 of the document, 11 and Figure 22～25) is designed like this, thereby by connecting and banking motion mounts and dismounts.The locking system (Fig. 5～10) that is used to lock the floor minor face is designed like this, thereby by promoting to utilize engaging to link together toward each other, but when the floor minor face did not have destroyed or do not injured in some cases, this locking system can not be disassembled.

Patent documentation WO 9747834 has introduced some floors, by rotating or engaging, these floors are fixed and dismantle (Fig. 2 among the WO 9747834～4 and accompanying drawing 14a～14c), on the one side on these floors, has groove, outside the connection plane of bar in projection below the described groove and when extending beyond two floor upsides and connecting.This with the floor opposite edge on formed complementary portion cooperatively interact, thereby two identical floors can be joined together.The total characteristic on these floors is that the upside of slip feather on the floor and the corresponding upward interface of groove are the planes, and parallel with the upper surface on floor.Utilize on the one hand the locking surface of slip feather upside, utilize the upside of lower lip or the bar of groove below on the other hand, obtain to stop to connect the floor connection that the plane is drawn back by crosscut ground.These locking systems also have shortcoming, and they require to extend to the bar portion that connects outside the plane, cause also causing waste of material in the adjoining edge that forms groove.

For the dissimilar floors of mechanical connection, multiple suggestion is proposed, wherein when using wood fiber and wooden base panel material, waste material is few, can produce with effective means.Patent documentation WO 9627721 (Fig. 5 a of accompanying drawing part～5b) and JP3169967 (at accompanying drawing 7a-7zb partly) introduced two types cause the little engagement connection of waste of material, but they have such shortcoming, and the dismounting on floor just is not easy.In these external these systems, can not use big lock angle, so that reduce the risk of being drawn back.The geometry of joint is unfavorable for that the requirement material has the engaging of considerable deflection, must adapt to the requirement that big surface portion must accurately be adjusted each other aspect manufacturing tolerance.It is more difficult that these surface portions that contact with each other also make the floor move relative to each other under lock-out state.

Shown in Fig. 8 a and 8b, patent documentation DE-A-1212275 has introduced another kind of system known per.This system known per is applicable to the athletic floor that is made of plastics, and can not utilize the big dish type cutting element manufacturing that is used to form sharp keen bottom cutting portion.When not using when having very big flexible material, just when being drawn back, can greatly be out of shape around the antelabium up and down of bottom cutting portion, this system known per can not be disassembled.If wish high-intensity connection, this type connection is not suitable for the floor that wood-base materials is made.

FR-A-2675174 has introduced a kind of mechanical connection system that is used for ceramic tile, described ceramic tile has complementary opposite edge, when the spring clip that use to separate, this spring clip is installed into the each interval certain distance, and is used to catch the raised line (bead) on the ceramic tile marginal portion.This connected system is designed to and can not be disassembled by rotation, shows as Figure 10 a is detailed, particularly Figure 10 b.

DE 20001225U1 has introduced the system of another kind of surrender.Yet this existing structure is very responsive, because the locked groove of lower lip weakens, has very big shortcoming.

DE 19925248 has introduced has the system that is directed upwards towards locking member.

As mentioned above, prior art system not only has shortcoming but also have advantage.Yet there is not a kind of system to be applicable to the reasonable production on floor with locking system, the production technology optimization of this locking system, waste material are minimum, lay and disassembling function the best, it can be used to have the floor of high-quality, intensity and function under the laying state.

An object of the present invention is to satisfy this requirement, a kind of best lock system and a kind of best floor of floor is provided.Another object of the present invention provides a kind of engagement connection that can produce with rational method.By foregoing and the content that will introduce hereinafter, it is clearer that the present invention will become.

Summary of the invention

A kind of floor and a kind of openable locking system, it is included in bottom cutting portion on the long limit, floor and the projection slip feather on another long limit.Has locking surface in the corresponding upwards guiding apart from its most advanced and sophisticated a distance bottom cutting portion.Slip feather is in the same place with the engagement connection of passing through that bottom cutting portion is formed.Most preferred embodiment also is to dismantle by rotational motion (angling motion), this rotational motion center near surface plane and two in abutting connection with the intersection point between the public connection plane on floor.Can utilize the dish type cutting tool to process the interior bottom cutting portion (undercut) of slip feather groove of this locking system, the rotating shaft of described cutting tool is tilted in relation to each other, thereby form the bottom cutting portion first interior part of groove, form the locking surface of a more close channel opening that is set up then.

The feature of locking system according to the invention, floor and laying method is documented in the independent claims.Dependent claims defines the preferred embodiments of the present invention.In addition, according to hereinafter describing, it is clearer that advantages and features of the invention become.

Before introducing the concrete and preferred embodiment of the present invention in conjunction with the accompanying drawings, will introduce invention basic conception, desired intensity and function.

The present invention is applicable to the rectangle floor with first pair of parallel edges and second pair of parallel edges.In order to simplify description, hereinafter first opposite side is called long limit, second opposite side is called minor face.Yet should be noted that the present invention also is suitable for square floor.

High quality of connection

High quality of connection is meant when latched position between the floor tight fit in the horizontal and vertical directions.Do not bear load or under normal carrying situation, need not big visual gaps or gap big difference very not quantitatively everywhere between the adjoining edge, just can connect the floor.In high-quality floor, joint gap and gap difference quantitatively should be not more than 0.2 and 0.1 millimeter respectively.

Be inclined upwardly around adjoining edge

Usually, the long limit on floor is upwards rotated, thus the dismounting floor.Owing to connect with the stressed joint edge, contact with each other and rotate to move by top edge and can realize this rotation that makes progress in adjoining edge on the floor of initial position.Not only when changing the floor or movably during panel, upwards the possibility of rotating is extremely important.Many floors are that test is laid or improperly in abutting connection with door, locate to be laid in the corner etc.During laying, if be not compromised under the prerequisite at locking system, the floor can not be dismantled easily, will be important disadvantages.Can also can be inclined upwardly once more on intilted floor, when utilizing downward-sloping connection, bar always occurs being bent downwardly situation a little, thereby locking member is crooked backward downwards and be opened.If connected system suitable angle of no use and radius form, after laying, the floor can be locked with this kind mode, just can not be disassembled (taking up).When long limit connect by upwards rotate be unlocked after, minor face always can be drawn out along adjoining edge, if but minor face can be unlocked by upwards rotating, better effects if then.When the floor is long for example 2.4 meters the time, make that to pull out minor face more difficult, then advantage is more obvious.Should realize upwards rotating, the floor is jam and pinching each other not, thereby causes the damaged risk of locking system as safe as a housely.

Engaging

Should can lock the minor face on floor by the level engaging.This part that requires connected system is an elasticity and flexible.Even compare with engaging, long limit is inwardly rotated easier to be quicker, because some require floor level ground to connect such as the lay-up operation around door, if long limit also can be stuck, has more advantage.But when engagement connection, if the geometry of coupling part is inappropriate, the risk that exists the edge to rise.

The material cost of long limit and minor face

If the specification on floor is a 1.2*0.2 rice, the long edge connector of every square metre of ground panel is six times of minor face joint.Compare with long limit, lot of materials consumption is unessential with the expensive material that is connected at minor face.

Horizontal intensity

In order to obtain high strength, locking member generally must have the big angle of engagement, thereby locking member does not break away from (snap out).Locking member must height and width, thereby when bearing the floor when shrinking caused high tensile load owing to low humidity in the winter time, locking member does not rupture.This also is applicable in another floor the material of close lock slots.Minor face connects and have bigger intensity than the connection of long limit, because during shrinking in the winter time, tensile load is shorter in the distribution length on long limit at the distribution length ratio of minor face.

Vertical intensity

When bearing normal load, should be able to keep the floor level.In addition, because the surface of bearing pressure and moving relative to each other is for example gone up adjoining edge and may be caused sending frizzle, should be avoided in the motion of junction.

Mobility

Can lock all four sides, newly the floor that will lay must be moved along the floor that has been laid in latched position.Use the power of fair amount, should be able to realize this situation, for example use building block and hammer,, the floor can be combined having under level and the vertical visual gaps prerequisite that adjoining edge is not compromised that connected system simultaneously need not to be formed.Because long the connection causes bigger friction, the mobility on the long limit is more important than the mobility on the minor face.

Productivity

Reasonably use big rotary cutting tool, should be able to produce connected system with good accuracy and ability.

Measure

Good function, production tolerance and quality all require to be connected appearance profile and can be measured continuously and check.Key component in the mechanical connection system should adopt the mode of being convenient to produce and measure to design, and should be able to produce them in tens microns the margin of tolerance, should be able to measure them accurately, for example uses so-called measuring projector.If use wire cutting machine processing connected system, except certain production tolerance, connected system has identical profile in whole marginal portion.By sawing down some samples with saw saw floor, utilize measuring projector or measuring microscope to measure them, can measure connected system accurately.Yet reasonable production requires connected system also can be measured fast and easily under the prerequisite that does not adopt destruction methods, for example uses batchmeter (gauge).If key element quantity is few as much as possible in the connected system, using meter measurement is very easily.

The optimization of long limit and minor face

In order to make the floor best with least cost, as mentioned above, in view of their different qualities, long limit and minor face should be by preferably.For example long limit should preferably rotate, upwards rotates, locate and move, and minor face preferably engages and high strength.The optimum design on floor is should have different connected systems on long limit and minor face.

The possibility that adjoining edge laterally moves

Along with the variation of relative humidity, wooden base plate expands with the floor that generally includes wood fiber and shrinks.Expand and shrink usually from the top, it is bigger that surface course can just form the degree that the part of connected system moves than core.Because high level expansion raises or be crushed, or the gap occurs in order to stop adjoining edge part when drying, connected system should so be constructed, thereby allows motion, so that expansion and contraction are compensated.

Invention

The present invention is based on first understands, by using suitable production method, basically utilize machine, use diameter significantly to surpass the instrument of plate thickness, the enough timber of energy, wood-base materials plate (wood-based boards) and plastic material form the rational shape of high accuracy, and this type machine can carried out in the slip feather groove that connects the plane certain distance.Thereby the shape of connected system should be suitable for reasonable production, can carry out with very little tolerance.Yet, can not be that cost produces this compliance with other key property of sacrificing locking system and floor.

The present invention also understands based on second, based on this requirement that must be satisfied by the mechanical connection system of best-of-breed functionality.This understanding can realize in the mode of the unknown, for example by will a) designing connected system like this, between the different elements of system, have special angle, radius, gap, Free Surface and ratio, b) preferably utilize the material behavior of core, for example compress, prolong, bend

Song, tensile strength and compressive strength make up.

The present invention also understands based on the 3rd, is guaranteeing or is improving under the prerequisite of function and intensity, by in conjunction with manufacturing technology, connection design, material selection and preferably long limit, minor face, can provide connected system with low cost.

The present invention is based on the 4th understanding, connected system, manufacturing technology and measuring technique must be developed and be adjusted, thereby the key element that requires closed tolerance very is few as much as possible to a greater extent, and can measuring in producing continuously and check of being designed.

According to first aspect present invention, a kind of locking system is provided and has the floor of this locking system, be used for the first vertical direction D1, the second horizontal direction D2 with perpendicular to the third direction D3 of second horizontal direction all four limits on floor are linked to each other with the corresponding edge machinery on another floor with same lock system.

The mechanical connection system that on two limits, floor, can have dismountable known type, it can laterally move under lock-out state, and by inwardly rotating around adjoining edge or utilizing the level engaging locked.On other two limits, the floor has locking system according to the invention.The floor can have locking system according to the invention on all four limits.

At least two relative edges in floor have the connected system that meets the present invention's design, this connected system comprises slip feather and the slip feather groove that is limited by upper lip and lower lip, top and outside at slip feather have upwards leader, and the slip feather groove has bottom cutting portion with top within it.The upwards leader and the bottom cutting portion of slip feather groove on upper lip of slip feather have locking surface, and described locking surface resists and stops horizontally separated perpendicular on the horizontal D2 that is connected the plane.Slip feather and slip feather groove also have being parallel to the D1 direction that is connected the plane and stop the area supported that coacts that vertically separates.At least on the lower lip of the bottom of slip feather and slip feather groove, has such area supported.On top, the locking surface that coacts can be used as the upper support surface, but the upper lip of slip feather groove and slip feather preferably have independent upper support surface.Slip feather, slip feather groove, locking member and bottom cutting portion are designed like this, thus can use have the diameter also bigger than ground plate thickness tool processes they.Utilize its leader that makes progress, lower lip bending, slip feather can be inserted in slip feather groove and its bottom cutting portion, thereby the upwards leader of slip feather can insert in the bottom cutting portion by the level engaging.Lower lip is shorter than upper lip, is convenient to form the bottom cutting portion with locking surface, has relative big inclination angle between the surface plane on this locking surface and floor, thereby gives bigger horizontal lock power, and it can combine with the elasticity lower lip.

According to second aspect present invention, the floor has two marginal portions that are formed with connected system according to the invention, slip feather has upwards leader, by engaging, slip feather with the leader that makes progress can be inserted in slip feather groove and its bottom cutting portion, when adjoining edge contacted with each other on the maintenance floor, by upwards rotating, slip feather can leave the slip feather groove.

In addition, slip feather can be manufactured has elasticity, thereby is convenient to engage at minor face after the long limit on floor has been joined together.Thereby the present invention also relates to engagement connection, by upwards rotating under the prerequisite that contacts with each other in last adjoining edge, described engagement connection also can be released.

The detailed introduction of preferred embodiment

Hereinafter introduce the floor 1 that is equipped with mechanical locking system of the present invention, 1 ' first preferred embodiment in conjunction with Figure 11 a and 11b.For the ease of understanding, schematically illustrate connected system.Should be emphasized that other preferred embodiment that use will be introduced hereinafter also can be realized better function.

Figure 11 a and 11b schematically illustrate the section by junction between long relatively marginal portion, the limit 4b on the long limit marginal portion 4a on floor 1 and another floor 1 ';

The upper surface on floor is located substantially in the interior HP of common surface plane, and adjoining

edge part

4a, 4b were engaged with each other in vertical the connection in the VP of plane.Mechanical locking system cause the floor vertical direction D1 with perpendicular to the horizontal direction D2 that is connected plane VP in toward each other the locking.With during floor and the floor covering layers in the row of floor, a floor (1 ') however can connect plane VP in D3 direction (seeing Figure 19) upper edge along another floor (1) and move.This floor that can be used to for example will be arranged in delegation of moving locks together.

In order to provide perpendicular to vertical plane VP and to be parallel to the connection of two adjoining edge part of horizontal H P, the floor has a slip feather groove 36 that is positioned at connection VP inboard, plane on an one marginal portion 4a, be formed with slip feather 38 on another adjoining edge 4b, slip feather 38 exceeds and connects plane VP.

In this embodiment, floor 1 has core or reel portion 30, and it is bearing in outer surface of wood surface layer 32 and the balance layer on its dorsal surface 34 on its leading flank.Floor 1 is a rectangle, has second locking system on two parallel minor faces.In certain embodiments, this second locking system can have identical design with the locking system on the long limit, but the locking system on the minor face also can have the design different with mechanical locking system of the present invention or be exactly a kind of known mechanical locking system.

As being used for explanation but non-limiting example, the floor can be that thickness is that 15 millimeters, length are that 2.4 meters, width are 0.2 meter parquet.Yet the present invention also goes for square parquet or has the parquet of different size.

Core 30 can be sheet type (lamella type), is made up of the narrow wooden unit of the timber system of cheap type.Surface course 32 can have 3～4 millimeters thickness, forms by ornamental hardwood, and by japanning.Balance layer 34 on the dorsal surface can be made up of the veneer of 2 millimeters thick.In some cases, can use dissimilar materials, be used to optimize the characteristic of the single part in floor in the different piece on floor.

As mentioned above, mechanical locking system according to the invention comprises the slip feather 38 on the opposite adjoining edge part of slip feather groove 36 and this floor 4b on the adjoining edge part 4a of floor.

Slip feather groove 36 is limited by upper lip 39 and lower lip 40, and has the nip form, and this nip has opening between two

antelabium

39,40.

The various piece of slip feather groove 36 is more clearly illustrated in Figure 11 b.The slip feather groove is formed on core or the core 30 and extends from the edge on floor.Above the slip feather groove, have the upper rim or the adjoining edge surface 41 that extend up to surface plane HP.In the open interior of slip feather groove, have the engagement of going up or area supported 43, in the case, surface 43 is parallel to surface plane HP.This engagement or area supported become a tilt-lock surface 43, between this locking surface and the horizontal H P angle just lock angle be A.Have surface portion 46 in the locking surface inboard, it forms the top boundary surface of the bottom cutting portion 35 of slip feather groove.The slip feather groove also has the bottom 48 of lower lip of extending downwardly into 40.At the upside of this flange, have engagement or area supported 50.The outer end of lower lip has adjoining edge surface 52, and it has certain distance apart from connecting plane VP.

The shape of slip feather is also shown in Figure 11 b best.Slip feather is made by the material of core or core 30, when this adjoining edge part 4b when adjoining edge part 4a in abutting connection with the floor is connected, described slip feather extends to and connects outside the VP of plane.Adjoining edge part 4b also has upper rim or goes up connection surface 61, and it is along connecting the root that plane VP extends downwardly into slip feather 38.The upside of slip feather root has the engagement of going up or area supported 64, and in the case, it extends to the upwards tilt-lock surface 65 of leader 8 near the slip feather end.Locking surface 65 meets with the upwards guide surface part 66 of the upper surface 67 of leader 8 that ends at slip feather.Intersect with the inclined-plane that is used as guide surface 68 on surface 67.Guide surface 68 extends to the end 69 of slip feather.69 lower end also has an inclination to extend downwardly into the guide surface 70 and an engagement or an area supported 71 of the lower limb of slip feather endways.When machinery links to each other each other on two such floors, this supporting plane 71 cooperatively interacts with the area supported 50 of lower lip, thereby their upper side is positioned at same surface plane HP, and meet at the connection plane VP perpendicular to surface plane HP, thereby the last adjoining edge surface 41,61 on floor is engaged with each other.Slip feather has a following adjoining edge surface 72 that extends to downside.

In this embodiment, have independent engagement or area supported 43,64 on slip feather groove and slip feather respectively, under lock-out state, they are engaged with each other, cooperatively interact with the

lower support surface

50,71 on lower lip and the slip feather, be provided at perpendicular to the locking on the D1 direction of surface plane HP.Will be hereinafter among described other embodiment, locking

surface

45,65 is used, it both had been used as the locking surface that on the D2 direction that is parallel to surface plane HP two floors is locked together, and was used to resist the area supported perpendicular to the motion on the D1 direction of surface plane HP again.In Figure 11 a, 2b illustrated embodiment, locking

surface

45,65 and

mating surface

43,64 coact as this intrasystem upper support surface.

See obviously that from figure slip feather 38 extends to and connects outside the VP of plane and in its free outer end or terminal 69 have upwards leader 8.Slip feather 38 also has locking surface 65, when two floors are linked to each other by machinery, locking surface 65 cooperatively interacts with interior locking surface 45 in the slip feather groove 36 on the floor, thereby their leading flank is positioned at same surface plane HP and is meeting with the vertical plane VP that is connected of surface plane HP.

Shown in Figure 11 b, slip feather 38 has the surface portion 52 between locking surface 51 and connection plane VP.When two floors connect, surface portion 45 engagements of surface portion 52 and upper lip 8 are in order by inside rotation or engaging slip feather to be inserted in the nip, shown in Figure 11 a, 11b, between locking surface 65 and surface portion 57, slip feather can have inclined-plane 66.Inclined-plane 68 can be set between slip feather terminal 69 and the surface portion 57 in addition.By having an angle that tilts to surface plane, and this angle is littler than the inclination angle A of locking

surface

43,51, and inclined-plane 66 can be used as targeting part.

In this embodiment, the area supported 71 of slip feather is arranged essentially parallel to surface plane HP.Between the end 69 of this area supported and slip feather, slip feather has an inclined-plane 70.

According to the present invention, lower lip 40 have be used for slip feather 36 on the area supported 50 that cooperatively interacts of respective support surfaces 71.In this embodiment, this area supported has certain distance apart from nip bottom 48.When two floors are connected to each other together, between corresponding engagement between the area supported 50,71 and on upper lip 39 engagement or area supported 43 and the slip feather or area supported 64, all there is engagement.Use this mode, obtain perpendicular to the locking on the D1 direction of surface plane HP.

Best, look from the direction parallel with surface plane HP, at least the major part of nip bottom 48 than slip feather outer end or terminal 69 further from connecting plane VP.Utilize this design, simplified manufacturing to a great extent, be convenient to a floor and move along connecting the plane with respect to another floor.

Another key character of mechanical locking system of the present invention is to look from the intersection point that the C point just connects plane VP and surface plane HP, and all parts of the lower lip 40 that links to each other with core 30 are positioned at outside the LP2 of plane.Compare with the lock plane LP1 parallel with plane LP2, plane LP2 is further from described C point, and the locking

surface

45,65 that cooperatively interacts of plane LP1 and slip feather 38 and nip 36 is tangent.With respect to surface plane HP, these locking surface inclined degree maximums.Because this design is as mentioned below, be used for machine floor edge big dish type rotary cutting tool partly by use, can process bottom cutting portion.

Another key property is that lower lip 40 is resilient, and it is shorter than upper lip 39.This guarantees to use big dish type rotary cutting tool to produce bottom cutting portion, because with respect to surface plane HP, big dish type rotary cutting tool can be set has big relatively angle, has bigger lock angle A thereby locking surface 65 can be manufactured.Big lock angle has obviously reduced the downward composition that causes that tensile load rises.Though it is flexible this means lower lip, connected system will have high strength, thereby have the ability of the limited downward composition of antagonism, thereby under low engaging resistance, obtain high latching force.High engaging resistance causes the engaging difficulty, has increased the risk of infringement floor edge.The inventor have been found that by make lower lip have suitable thickness and the length that can work in the preferred connected system, the most frequently used material can be manufactured in the floor has abundant elasticity, and sufficient latching force is provided.

Figure 12 a～12c has shown by crooked lower lip 40 makes two floor engagings.Shown in Figure 12 b, have in lower lip under the crooked situation of minimum degree, just can realize engaging, the surface plane on floor is basically at equal height simultaneously, and this has reduced the risk of breaking.

Figure 13 a～13c shows that the locking system that meets Figure 12 a～12c also can and rotate by rotation (upward angling) upwards when mentioning (taking-up) and laying.Upper and lower antelabium 39 and 40 and passing through of being formed of slip feather 38 make a floor guarantee that around upwards rotating two floors by mechanical connection are disassembled separately near the center of rotation that connects intersection point C between plane VP and the surface plane HP with respect to another floor, thereby the slip feather on this floor is rotated out from the nip on another floor.

Engagement connection according to the invention not only can be used in the long limit on floor but also can be used on the minor face.

Yet Figure 14 and 15 shows a modification of the present invention, the most important thing is that it is applicable to along the minor face engaging by the floor of making such as relative relatively hard materials such as hardwood or hard fiber board.

In this embodiment, the degree of depth of slip feather groove surpasses the desired degree of depth of reception slip feather.Therefore make lower lip 40 have higher bendability.In addition, locking system has the tenon fond of gossip that is formed with thick locking member 8.

Locking surface

45,65 also has very big angle of slope.Dotted line is represented snap action.

By making a floor upwards rotate and be bent downwardly a little the lower lip 40 on another floor, the design that meets Figure 14 and 15 allows two floors to be disassembled separately.Yet in other preferred embodiment of the present invention, when the dismounting floor, need not to be bent downwardly lower lip.

In latched position, can vertically move the floor along connection.Therefore for example dismantle after the long limit, vertically pull out and dismantle minor face along connection by upwards rotating.

For the ease of making, slope inwardly, be inclined upwardly, engage and also reducing the risk of breaking in the latched position mobility, all are not used in last adjoining edge, vertical and horizontal adjoining edge and form not contacting each other in latched position that close-connected surface should be formed, also do not contact during being preferably in locking and dismounting.Thereby allow these coupling parts not require high tolerance during fabrication, reduce along the horizontal friction when mobile of adjoining edge.The surface or the part of discontiguous connected system are 46-67,48-69,50-70 and 52-72 each other in latched position.

Meeting the preferred embodiment connected system can be made by the different materials combination.Upper lip 39 can comprise rigidity and hard upper surface 32 and as the softer bottom of core 30 parts.Lower lip 40 can comprise softer equally top 30 and make down soft 34 by another kind of timber.The machine direction of three kinds of timber can be different.Thereby can provide a kind of connected system that utilizes these material properties.The close hard and rigid element that locking member according to the invention is set up, the elasticity of this part and compressibility are limited, engage function simultaneously and are realized by softer following and elastic part.Should be noted that connected system can be made by commaterial.

Figure 16 a～16c explanation meets an example on floor of the present invention.This embodiment shows that especially connected system has different designs on long limit with minor face.At minor face, by having big lock angle, dark slip feather groove and the upper lip of lacking than lower lip, locking surface has than low height simultaneously, so that reduce reclinate requirement, locking system is preferably engaging.On long limit, by rotating, this connected system is adjusted, and is used to connect/roll.

In addition, connected system can comprise different materials and combination of materials 30a, 30b and 30c.Can select different materials with minor face on long limit.For example the groove on the minor face 36 can be by for example making than slip feather 38 timber harder and more toughness, and slip feather 38 is by hard and rigidity and have and the material of growing limit core 30 different qualities is made.On minor face with slip feather groove 36, for example can select a kind of timber 30b, it is more pliable and tougher than the timber 30c on other minor face that is formed with slip feather 38.For the parquet with lamination core, more convenient, its upper side is made by different timber with downside, and core is made up of the gummed piece.This structure more may change the combination of material, so that optimizational function, intensity and cost of production.

Can change material along edge lengths.Thereby for example the piece between two minor faces can be made by different timber or material, thereby can select suitable characteristic according to their distribution, improves laying, intensity etc.By fiber on long limit and the minor face different towards, can realize different qualities, also can on minor face, use plastic material, for example on the different piece of long limit.If the part of floor or its core is when forming such as the veneer with which floor, these layers can be selected, thereby on top with minor face on upper lip, slip feather and lower lip all parts are made up of different materials, or have different fiber orientation etc.Thereby has different qualities at aspects such as intensity, bendability, mechanicalnesses.

The bottom that Figure 17 a～17c shows slip feather is how with respect to the basic principle of lower lip 40 designs, thereby in the connected system that comprises rigidity upper lip 39 and elasticity lower lip 40, be convenient to realize level engaging according to the invention, have bottom cutting portion or lock slots 8 on the described upper lip 39.In this embodiment since thicker or by harder and more rigid material make, compare with other parts, upper lip 39 is harder.Lower lip 40 can be thinner, softer, and lower lip 40 is easy to bending when engagement connection.Owing to limit the maximum deflection of lower lip 40 as much as possible, to compare with alternate manner, engaging is more convenient for carrying out.Figure 17 a shows that the bending of lower lip 40 will be increased to maximum level B1, and just slip feather 38 inserts slip feather groove 36, and circular targeting part contacts with each other.When further insertion slip feather 38, lower lip 40 will stop to engaging and till locking member 8 is inserted into its final position in bottom cutting portion 35 fully to back bending is right and wrong.Following and anterior 49 of slip feather 38 should be designed, thereby this part 49 does not make lower lip 40 be bent downwardly, and alternative scheme is to utilize lower support surface 50 that lower lip 40 is bent downwardly.This part 49 of slip feather should have such shape, thus when lower lip 40 when the outside of the following mating surface 50 of slip feather 38 is bent, this part 49 be in other lower lip 40 of maximum deflection level and contact or do not contact.If slip feather 38 has such shape, just in the position by the covering lower lip shown in the dotted line 49b, the crooked B2 shown in Figure 17 b can be obviously bigger, may cause bigger friction when engaging, and the damaged risk of tie point occurs.Figure 17 c shows can limit maximum deflection by such design slip feather 38 and slip feather groove 36, and just slip feather has space S 4 down and between outside 49 and the lower lip 40.Upper lip is manufactured has bigger rigidity, and lower lip has bigger elasticity, thereby influenced by indoor humidity and during pucker ﹠ bloat, reduce and lay the risk that the edge on the upper side of floor, back upwards rises when the floor.Big rigidity upper lip and combining of locking surface cause need use bigger along the horizontal pulling-off force of tie point.The bending of lower lip helps to reduce the risk that the edge rises.

After the long limit of locking, usage level engaging when the engagement connection minor face usually.Fashionable when long checkpost, connected system of the present invention is engaged in the position that is inclined upwardly a little with a floor.Figure 18 has shown this clamped position that is inclined upwardly.Lower lip 40 only needs crooked not half, so that the targeting part 44 with in the lock slots of targeting part 66 guiding of locking member is contacted, thereby by rotating, locking member can be inserted in the bottom cutting portion 35.

The problem that the minor face that Figure 19 and 20 has also described latter two floor 2a that has been connected with another first floor 1 on long limit and 2b may occur when engaging.When floor 2a was connected by snap action with floor 2b, the inner corner portion 91 and 92 on 1 long limit, the most close first floor was positioned at same plane.Because the long limit of two floor 2a, 2b links to each other with same floor 1 respectively, so above-mentioned phenomenon occurs.As show that slip feather 38 can not insert slip feather groove 39, so that lower lip 40 is bent downwardly shown in Figure 20 b of C3-C4 section.Shown in section C3-C4 among Figure 20 a, on the external angle 93,94 on another long limit, by making floor 2b pressurized and be inclined upwardly with respect to the height of locking member 8 automatically, slip feather 38 can insert slip feather groove 36, and begins to make lower lip 40 to be bent downwardly.

The inventor has been found that when the end at slip feather is formed with and is directed upwards towards part and when being inserted in the slip feather groove that is equipped with bottom cutting portion, may occur laterally moving in same plane with inner corner portion and engages relevant problem.Big resistance appears in these problems when causing engaging, and occurs the risk of breaking in connected system.Guarantee that by suitable design connection and selection material at distortion of a plurality of coupling parts and crooked material, can address the above problem.

When engaging the connected system of this particular design, following situation appears.When mobile, the outer targeting

part

42,68 of slip feather and upper lip cooperatively interacts horizontal, forces the upwards leader of slip feather or the below that locking member 8 is positioned at upper lip 9 outsides.Shown in arrow among Figure 20 b, slip feather is bent downwardly, and upper lip is bent upwards.Bight 92 among Figure 19 is upwards pressed by the lower lip 40 on the long limit of crooked floor 2b, and the upper lip on the long limit of the floor 2a that bight 91 is bent upwards is to pressing down.Connected system should have such structure, thereby these four kinds distortion sums are very big, thereby locking member can and be engaged in the bottom cutting portion 35 along the upper lip slip.Be well known that and for the ease of engaging slip feather groove 36 broadened.Non-being well known that, if be generally that the slip feather of rigidity is designed can be crooked when engaging, also be very good scheme.

Figure 21 has shown this example.In vertical plane VP inboard, processing groove or similar position 63 on the slip feather He on the interior part.The whole length of slip feather just can be extended from its inside to its outside length PB, for example can be manufactured also bigger than half of floor thickness T.

Figure 22 and 23 has shown how crooked the part of connected system is when the inner corner portion 91,92 (Figure 19) of two floor 2a and 2b and external angle 93,94 (Figure 19) engaging.In order to simplify manufacturing, require only thin flange and slip feather bending.In practice, certainly material thickness, bending property, structure, all parts of bearing pressure will be compressed and according to and crooked different degree.

Figure 22 a shows external angle 93,94, and Figure 23 a shows inner corner portion 91,92.These two figure have shown the position when floor edge contacts with each other.Design connected system like this, thereby even in this position, the outermost end of slip feather 38 is positioned at also within the outer end of lower lip 40.When still continuing to promote the floor opposite to each other each other, shown in Figure 22 b and 23b, slip feather 38 will upwards be pressed floor 2b in inner corner portion 91,92.Slip feather 38 will be bent downwardly, and floor 2b will upwards rotate at external angle 93,94.The slip feather 38 that Figure 23 c is presented on inner corner portion 91,92 positions will be bent downwardly.Shown in Figure 22 c, at external angle 93,94, slip feather 38 is bent upwards, and lower lip 40 is bent downwardly.Shown in Figure 22 d and 23d, along with still continuing to promote the floor opposite to each other each other, this bending is continuous, and shown in Figure 23 d, lower lip 40 also is bent downwardly in inner corner portion 91,92.Figure 22 d and 23e have shown fastening state.If thereby slip feather 38 also has elasticity, when the floor after the locking of two other limits, when the floor engages, when slip feather and groove contact with each other,, be convenient to engaging significantly if the outside of slip feather 38 is positioned within the outside of lower lip 40 in same plane.

Within the scope of the invention, there are several modification.The inventor has made and has assessed a large amount of modification, just makes the different piece of connected system with the differently panel material with different in width, length, thickness, angle and radius and identical plastics and wooden panel.All connected systems are in that to put upside down dislocation tested, and test engaging, test slip feather and slip feather groove relatively rotate with respect to each other (angling), use the combination of system in described system and the prior art on long limit and minor face.Locking system is manufactured, and locking surface also is the upper support surface, and slip feather and slip feather groove have a plurality of locking members and lock slots, the horizontal lock device with locking member and lock slots form that the bottom of lower lip and slip feather is formed.
