Description

Elbow-board with cable passage

Technical field

The present invention relates to be used for for example spreading the structural member of layer by the disclosed elbow-board of patent documentation DE 202 05 774 U1.

Background technology

Comprise elbow-board by the disclosed structural member of patent documentation DE 202 05 774 U1, it can reasonably be connected with the second elbow-board moulding, thereby both also stitches parallel and while and shared surperficial parallel grafting with shared being connected with shared plane is vertical.If according to the present invention the shop layer of this elbow-board as floor or wall backplate used, then can cancel the use binder.

Forming the material of the above-mentioned type elbow-board can select arbitrarily in principle.But particularly adopt all or the elbow-board of mainly forming by wood materials according to the present invention.Elbow-board can be made by timber fully.Preferred elbow-board comprises the bearing support of for example being made up of HDF.One or more veneer composite plate of the top installation of bearing support.The following installation lining or the paper of bearing support to play the effect of tension, are avoided distortion thus.

In addition, fully known or mainly be made up of plastics and can not have the interconnective elbow-board of binder, for example patent documentation US 04426820 has disclosed.

The invention still further relates to a kind of structural member that is used for composite floor board.This structural member comprises the elbow-board that has the wood materials base plate.As at present preferred HDF of wood materials and MDF.The wood materials of another kind of type is made up of the gummed shaving board.The top installation of base plate comprises the decorative layer together with topping.Topping particularly is made up of the resin with picture corundum or this abrasion resistant particles of SIC.Installation tension paper below base plate is to avoid above-mentioned distortion.

Engineering is used as the base plate on the elbow-board equally with composite plate.In this case, it is a kind of ply of paper of resin impregnation mutual extrusion.Patent documentation WO 96/27719 A1 and WO 96/27721 A1 disclose the engineering composite plate.

When making the combined tessera plate, Tetefol and base plate are transported to extruder jointly.Under transfer heat and pressure, paper and base plate are glued together.In this regard, facing paper has had the layer that comprises abrasion resistant particles.

Patent documentation EP 1 024 234 B1 introduce elbow-board and the pucker ﹠ bloat phenomenon occurs.This phenomenon causes the seam between the elbow-board undesirable cracking to occur usually.Moisture and dust also can enter in the seam of cracking nocuously.

Patent documentation DE 202 05 774 U1 disclose has tightrope shape or bar-shaped parts between elbow-board.Tightrope shape or bar-like member completely or partially are made up of compression material.Tightrope shape or bar-like member can remedy the pucker ﹠ bloat phenomenon, thereby can avoid the slit on the seam.

The pucker ﹠ bloat phenomenon particularly can impact under the layer situation of 30 square metres and more large-area shop.Just can provide large-area shop layer by tightrope shape or the bar-like member itself that between elbow-board, installs the above-mentioned type compression material additional.

Elbow-board according to type of the present invention can comprise one or more above-mentioned feature.

Generally need cabling, lead and/or flexible pipe in the room.For example desk can be in the central authorities in room.For the line of computer, phone, desk lamp etc. is provided, must from the wall to the desk, lay stube cable.Generally can not lay cable or flexible pipe on the ground, because can trip the people like this.

For addressing this problem, known is that floor with minute cotton covered wire etc. is by the room permanent wiring.Perhaps at the underground cable passage that permanent wiring has been arranged.As selecting or replenishing, also cable can be guided to from above on the desirable position by ceiling.

Underground distribution spends high and is difficult to afterwards and changes.If cable is drawn from ceiling, so particularly outward appearance there is adverse effect.The expense of doing like this is also quite big.Undertaken by the professional on the design principle of disposal wires, must once be fixedly mounted on the ceiling.

May also need for other reasons for example shop layer of having mated formation as shop, floor layer is changed.

Summary of the invention

The object of the present invention is to provide the structural member of shop layer, its flexible operation that is to say, for example can provide cable or hose passages neatly.

Purpose of the present invention is achieved by the structural member with first claim feature.Formation with advantage comes from dependent claims.

Comprise elbow-board and/or structural member bar-shaped or tightrope shape parts or hollow body by being provided for particularly shop, floor layer, can cable or flexible pipe and this structural member is integrated.Because elbow-board can be mated formation at any time on seamless floor or similar ground, but also can remove again at an easy rate, can for example peg graft flexibly along hollow body.Bar-shaped or tightrope shape parts can directly use as electric wire or the hose-like formation.Can power without a doubt in the room.Do not need to spend big ceiling structure or designs fix installation in advance.

In one embodiment, under the assembled state of structural member, be provided for passing the passage shape cavity of cable or flexible pipe.Like this, the room at any time can be for cabling or flexible pipe use in layer inside, shop afterwards.

In a kind of embodiment with advantage, structural member comprises elbow-board, and it is by constituting especially for matrix that passes cable or flexible pipe and cover plate.Cover plate particularly can reasonably be connected with matrix in moulding.Then can be below cover plate cabling or flexible pipe.The work of mating formation is simple especially, because only need mat formation and subsequently cover plate is installed.

The installation of cover plate also can be finished by gummed.But what have advantage is that the cover plate moulding is reasonably fixing.This fixed form is operated simple especially on the one hand, can also cover plate be opened by plain mode in principle on the other hand again.So for example can lay other cables afterwards at an easy rate or change existing cable.

Comprise matrix and cover plate the elbow-board structure can with penetrate that cable is irrelevant to be used as follows.What become one with cover plate can be doormat, ligthing paraphernalia, heating element or cooling element and/or the billboard that is easy to change.Doormat, ligthing paraphernalia, heating element or cooling element and the billboard that is easy to change can be simply from top installation, dismounting and/or maintenances.Being installed in ground advertising carrier can be strengthened by light effect.Doormat is being easy to replacing or cleaning with the old times.The possibility of passing cable has advantage under the described situation of this paragraph, but mandatory requirement not.That is to say, but for shop layer that flexible operating is provided with realize purpose of the present invention like this, not necessarily must have cavity below the cover plate.

Structural member has advantage ground and comprises and be used to pass the matrix that cable or flexible pipe can be connected with other elbow-boards.From shared surface and/or shared bottom surface finding, preferably there is one or more to be used to pass the space of cable or flexible pipe on vertically in the matrix.Cable passage can be considered to add in the layer of shop in advance.In addition, for the cost reason, the shop layer can be as constituting by traditional elbow-board from commonly known in the art.Being connected particularly between the elbow-board and/or between elbow-board and the matrix finished by means of traditional groove-embedding feather joint.Groove-embedding feather joint can be glued together.Groove-embedding feather joint has advantage ground and comprises for example known other plug connectors from EP 1 024 234 B1.Can not having binder then connects.Also can take elbow-board apart in principle then afterwards.The cable passage that has laid can change by separately spreading layer and laying again then afterwards.Cable passage can be installed on the desirable position without difficulty afterwards.

If matrix has cover plate, utilize space in the cover closure matrix according to purpose so.The space is used to pass cable or flexible pipe.Matrix is the elbow-board on the meaning of the present invention together with cover plate.

The cover plate that is used to seal the space of passing cable or flexible pipe has advantage ground and has keeper in the bottom surface, can moulding reasonably be fixed at least one structural member by this keeper cover plate, and particularly moulding reasonably is fixed on the above-mentioned matrix.In the simple embodiment of a kind of processing, keeper is made up of the sidewall that perpendicular leads downwards.Particularly on the end of sidewall separately, the plug connector with at least one lateral projections.The suitable elasticity of sidewall constitutes.Plug connector plays the effect that moulding is reasonably pegged graft thus by the fixing back that is in lug boss on the hypotaxis spare like this.

For reaching the purpose that stably keeps cover plate especially, plug connector separately can not separate cover plate owing to simple pulling force motion like this around the lug boss of biting separately with structural member.In order to separate cover plate, need at first cover plate to be pulled down from the layer of shop together with the structural member of subordinate, and for example make sidewall pass the space by means of for example suitable back pressure of screwdriver.Can be according to embodiment by cover plate being separated with respect to parallel the moving of structural member.If being in the room that personnel arbitrarily enter, cable passage need prevent that people or children from touching, then preferred this scheme.Perhaps, with personnel arbitrarily enter in the room cable passage for example screw be fastened on the structural member, it only just can be opened by instrument.

In the more simple embodiment of a kind of operation, above-mentioned plug connector is not like this around biting or bite from behind single or a plurality of lug bosses, by on draw cover plate that it no longer can be separated with the shop layer.If require simple to operate and do not need to prevent especially any contact, preferably this scheme.

According to purpose, have a plurality of matrixes that have the space that is used to pass cable or flexible pipe, wherein, matrix particularly can interconnect like this by groove-embedding feather joint, makes these spaces be provided for passing a common-use tunnel or the shared groove of cable or flexible pipe.In this manner, can provide the passage of random length to be used to pass cable or flexible pipe.

Under the state that structural member is mated formation, particularly carry the cable of electric current to be in the space that is provided.What have advantage is to have at least one particularly structural member of cover-plate type, has plug, socket and/or at least one hole above.Cable or then can suitably be connected with plug or socket, thereby a kind of electric wiring of routine is provided.Hole on the cover plate is used for the flexible pipe on the requirement position or cable from being penetrated or draw at the desired position of layer, shop by the cable passage that for example constitutes by matrix and cover plate.

If cover plate is placed on the matrix, it and matrix constitute a shared flat surface so.Reach level and smooth combination thus, thereby can not form the lug boss that hacks.But formed surface can have the slightly bow structure of microprotrusion, for example can prevent to slip on the surface.Cable passage is preferably mated formation along ladder then.In this manner, it can satisfy dual-use function.Slip when particularly preventing person to go upstairs on the one hand.Bow structure also plays the effect at prompting special hazard position.Be used to pass cable or flexible pipe on the other hand.

Opposing end faces is particularly led to from an end face in the space that is used to pass cable or flexible pipe on elbow-board or the matrix, crack, a plurality of space can be interconnected to the passage of a perforation like this.

The space that is used to pass cable or flexible pipe on the matrix has advantage ground to be opened wide from a side and enters, and is to open wide from the shop laminar surface to enter.Can when mating formation layer, easily cable be penetrated in the space like this from top.Preferred then from the teeth outwards the rounding bow structure restriction of passage of leading to the space by projection.By rounding on relevant surfaces, these surfaces are slightly outwards expanded.Make the installation cover plate become easy thus with relevant therewith dead air space.Avoid damaging the edge thus.If cover plate has bow structure equally, have so that advantage ground is actual to be discovered less than the transition between matrix and the cover plate.

For moulding reasonably connects, the matrix with the space that is used to pass cable or flexible pipe is lobed bow structure or lug boss in inside, and the such acting in conjunction of keeper of they and cover plate can make cover plate pass through the location thus and be connected with matrix.

Matrix with the space that is used to pass cable or flexible pipe preferably includes lug boss, the subordinate cover plate that provides dead air space above being under closed state.Therefore cover plate is on the quite little surface.On the one hand, the accurately processing quite simply of little contact surface is to guarantee level and smooth shop laminar surface.On the other hand, little contact surface also can drop to quite little degree with the danger that for example dust granules formula is polluted.In addition, lug boss also can be divided into the space a plurality of zones, thereby cable can spatially separately lay when needed reliably.

If the space is not by cover closure, the space has advantage ground from the outside contact when mating formation layer so, and whole outwards expansion on the edge.Like this cover plate can be installed especially simply.Also can select cover plate to narrow down downwards, so that with its installation.

The space that is used to pass cable or flexible pipe can and have undercutting from the outside contact.Undercutting is a kind of special protection zone.Particularly can be with flimsy cable from packing into here, to prevent from for example to damage when mounted cable especially effectively.

In matrix with the space that is used to pass cable or flexible pipe and space, have under the situation of undercutting, they particularly spatially can be separated by lug boss and other zones in other spaces or the space according to purpose.Therefore the interior cable of the undercutting that is laid in obtains especially effectively protecting.Lug boss can also have the contact surface use of advantage ground as cover plate simultaneously.

In one embodiment, matrix can be used as heating element or cooling element formation or comprises heating element or cooling element.Therefore it play the effect of regulating room temperature.The shortcoming of floor heating is to react too slow.Also be difficult to control in addition.Be heating element or cooling element or comprise heating element by matrix, compare with the floor heating device of routine and can more directly contact with the room generation.Can reduce the known problem in floor heating device aspect greatly thus.

According to purpose, matrix and/or cover plate particularly are made up of this metal of aluminium.Metal can stably be processed into net structure and therefore preferred.

Under the situation of matrix with the space that is used to pass cable or flexible pipe and the elbow-board be made up of wood materials, the thickness of elbow-board equals the thickness of matrix according to purpose.Matrix can seamlessly be become one with the shop layer like this.Avoided the shop laminar surface undesirable lug boss to occur like this.

If matrix has the space that is used to pass cable or flexible pipe, the space is divided at least two zones by dividing plate with having advantage so.Can spatially separately lay a plurality of cables or flexible pipe then, for be easy to observe and/or the reason of safety this is desirable just.

Be used to the elbow-board that passes the space of cable or flexible pipe and for example be made up of wood materials if matrix has, matrix is connected by connector with elbow-board according to purpose so.Preferred this connector is equal to the sort of connector that is used to connect two conventional elbow-boards.Can without difficulty matrix be installed in then on any part of shop layer.

The connector of being spoken of in the last paragraph can be preferably reasonably both also interconnects with shared surperficial parallel and while two relevant structural members (elbow-board and/or matrix) moulding with shared surface is vertical with shared seam is vertical.Mat formation so simple especially, even and the layman also can operate.

According to the present invention in one embodiment, have the space between the elbow-board that two no binders are located mutually, being under the state of finally mating formation in the space is tightrope shape or bar-like member, and these parts particularly are made up of compressible material.In this regard, elbow-board also can be the matrix with cover plate.For example can have tetrafluoroethene as flexible material.But the material that preferably has the favorable elasticity characteristic.Therefore tightrope shape or bar-like member for example are made up of rubber.But with rubber phase than preferred silicones, because the silicones reset force higher than having with rubber phase.Fact proved that silicones has the reset force higher than rubber.

Having slit or space between two elbow-boards can be than existing between two elbow-boards under the situation in gap, stitches mobile elbow-board along a shared connection easilier.But preferably there is the gap, is easy to move with assurance.The gap of 1/100mm is enough for this purpose.

Above-mentioned slit or space particularly are in the surface of two elbow-boards that constitute floor or wall backplate visible part.Can see tightrope shape or bar-like member then from this surface.Under positioning states, tightrope shape or bar-like member are particularly determined size like this, make these parts fill up the width in slit fully.What have advantage is that tightrope shape or bar-like member are slightly wideer.Under squeezed state, be in inside, slit then.

By having slit or space between tightrope shape or the residing elbow-board of bar-like member, particularly be connected with elbow-board to compare and reduce friction with the sort of elbow-board of forming by wood materials with keeper integral body.That is to say that for example can provide and the whole elbow-board that is connected of this elbow-board according to the present invention, it is made up of wood materials, if but two elbow-boards are pegged graft mutually, move along shared connection seam quite easily again.Be in visible surface if having the slit of tightrope shape or bar-like member, new designability also is provided so thereupon.In seaming zone, for example can see the rubber or the silicone material of black.The surface of elbow-board can have strong contrast for this reason.Produce the new appearance effect that particularly in the combined tessera plate, did not disclose thus.If wish a kind of not too noticeable outward appearance, as long as tightrope shape or bar-like member just can be arranged in pairs or groups with this visible surface on color as seen so.Exactly can also decorate, have colored lace or colour edging on the surface of each elbow-board.Different therewith is that the user can freely select the color of lace and can also change afterwards.Expense that like this can be quite few changes the outward appearance of the elbow-board of having pegged graft, and need not to remove shop, floor layer.Therefore, the space that provides by two adjacent elbow-boards on the surface also provides the possibility that is easy to change appearance effect except being easy to ambulant technical advantage.

Tightrope shape or bar-like member can be pressed into afterwards or embed in slit or the space from the surface.But can also be connected, if particularly tightrope shape or bar-like member are made up of compressible material with elbow-board.Yet with the advantage that has in independent tightrope shape or the bar-like member embedding slit be afterwards, as long as also do not embed tightrope shape or bar-like member, just can mobile especially simply elbow-board.

If have the gap between the plug connector of projection and the corresponding space, can have contact surface vertical or undercutting so.If tightrope shape or bar-like member are connected with elbow-board during producer's delivery, when connecting then tightrope shape or bar-like member are roughly compressed.Although vertical contact surface for example still reaches connection by rotating around shared connection seam.

On the plug connector of projection and space even can have undercutting.If separate extruding with interconnective elbow-board is parallel with backplate surface, on the space of the plug connector of relative set and relative set, above-mentioned contact surface catches on mutually so then.By moving on the plane vertical and can not without damage throwing off with plug connector or between connecting with being connected seam.For example, constitute if the protruding sidewall of groove and plug connector are gone up elasticity endways, the alleged because undesirable disengagement of casual power effect is avoided itself in the prior art.Therefore, although the elastic edge of groove, if produce a kind of parallel with floor surface and be connected with shared that seam is vertical pegs graft especially reliably, so preferred this undercutting or at least with the vertically disposed contact surface in surface.

If the contact surface of the above-mentioned type is tilt distribution as patent documentation EP 0 843 763 B1 are disclosed, the protruding lower wall or the edge rigidity of so preferred groove constitute, so that a kind of with the shared parallel and vertical reliable grafting of connection seam is provided like this.If a kind of combination especially reliably between the elbow-board of wishing to mat formation even so Tu Qi edge also can rigidity constitute under the situation of contact surface vertical distribution, thereby can not thrown off by moving on the plane vertical with being connected seam yet.Other connectors also can rigidity constitute then as long as need.This is for example related to a kind of embedding tenon, the vertical grafting that it produces a kind of common surface of and elbow-board with groove.

If at first elbow-board is pegged graft mutually, there is a gap then, in the slit or space that produces of earlier tightrope shape or bar-like member being packed into from above so subsequently, so hardly just can be mobile especially simply along connecting seam with effort.Under the situation that the longitudinal side of two elbow-boards has connected and also leptoprosopy will have been connected, the elbow-board that special hope can have been pegged graft mutually stitches mobile along shared connection.This method for example has disclosed by patent documentation EP 0855482 B1.If particularly require to connect in order, although inserting state still can move elbow-board along shared connection seam, the embodiment with advantage is from top last embedding or be pressed in the slit with tightrope shape or bar-like member.

Tightrope shape or bar-like member typically have diameter or the width of 0.5mm at least, preferred 1mm at least, especially preferably 2mm at least.Width generally is no more than 10mm, and this is because wish bigger width for the reason of outward appearance.Preferable width is less than 5mm, particularly preferably less than 3mm.But for example can have littler or bigger width or diameter in principle for the reason of outward appearance.

The residing slit of tightrope shape or bar-like member generally has the width that is slightly less than tightrope shape or bar-like member, particularly if compression clearance or avoid dust and moisture to invade being connected the words of stitching.Tightrope shape or bar-like member are easy to then push be in the slit and also remain in the slit like this.But the slit also can have identical width.Just should avoid width or the diameter of the width in slit greater than tightrope shape or bar-like member because otherwise undesirable slit is left on the surface, and if tightrope shape or bar-like member embedded from the surface, these parts are easy to come off.Seamless state and fixedly tightrope shape or bar-like member are guaranteed in preferred tightrope shape or the interference fit of bar-like member in the slit then.

In one embodiment of the invention, tightrope shape or bar-like member are under inserting state between two planes that produce the grafting effect.It for example can be the plane that is called contact surface here.Tightrope particularly is made up of picture rubber or this elastomeric material of silicones then.Before two elbow-boards are pegged graft, tightrope shape or bar-like member are placed on one of above-mentioned grafting plane.Tightrope shape or bar-like member then particularly the part be in the depression position in and the continuation or even be pressed into fully in this position, if elbow-board is pegged graft mutually.For example with an elbow-board by for example being pressed into like that in second elbow-board by patent documentation DE 20008708 U1 are disclosed.Meanwhile, tightrope shape or bar-like member are pressed in the depression position.Owing to have the gap, the direction of an elbow-board to another elbow-board can be continued to insert now.The position of caving in thus obtains discharging again.Tightrope shape or bar-like member are lax also to be entered between two (contact) planes with grafting effect like this.

For example, if lobed sidewall, it is gone up endways by a rectangle and carries out the transition in the plug connector, and so preferred above-mentioned depression position directly is in the transition region front of plug connector.Embed tightrope shape or bar-like member in this depression position or for example vulcanize installation here by producer.

In the above-described embodiment, though according to purpose under the relaxed state of tightrope shape or bar-like member, still can leave slit or space on the surface.Then the second tightrope shape or bar-like member are packed in this slit.Can be chosen in an elbow-board to a tightrope shape or a bar-like member of being made up of compressible material has been installed on the surface of edge fit.The advantage of doing like this is to obtain above-mentioned design effect, perhaps remedies particularly in fact inevitable tension force in wood materials.

If have first and second tightrope shape or the bar-like members in the seam of the connection between two elbow-boards, the advantage that produces in addition is so here, can at first roughly separately push elbow-board by means of corresponding instrument from the teeth outwards.Formation can embed the position of tightrope shape or bar-like member here without a doubt like this.If tightrope shape or bar-like member embed to a certain extent, take away instrument so.It is lax so then to be in two tightrope shape or bar-like members between the grafting contact surface, and making does not have the slit on the surface.

If the connection seam inside that has between two contact surfaces of grafting effect has a tightrope shape or bar-like member, can adopt a kind of embodiment that two elbow-boards are connected, method is that the connector of an elbow-board is at first packed into by moving both vertically with respect to shared surface after two elbow-boards in the connector of second elbow-board.Meanwhile tightrope shape or bar-like member can be pressed in the position of for example caving in accordingly.Subsequently elbow-board is passed relatively.In a kind of corresponding formation, the embedding tenon enters in the groove and plays the grafting effect perpendicular to shared surface like this when this relative passing.Above-mentioned tightrope shape or bar-like member relax at last and enter between the contact surface of two grafting.

Tightrope shape or bar-like member can have circular or leg-of-mutton diameter.If but pack into from the surface at last, what have advantage so is that tightrope shape or bar-like member be hook-shaped formation on two relative sides.If with the tightrope shape or bar-like member is corresponding is pressed into from above in the slit, these hook the effect of barb so.If tightrope shape or bar-like member are pressed in the slit, the visible surface of tightrope shape or bar-like member can flush formation so, flushes sealing so that produce with the remaining surface of elbow-board like this.

With the surface opposite of visible tightrope shape or bar-like member from the surface, can have a for example space of projection so that tilt away from hook can be pressed in the slit better.

Under having hook and projection, in this embodiment in space, can have advantage ground and realize a kind of interference fit.

Tightrope shape or bar-like member have advantage ground and comprise in fact non-stretchable fiber.This fiber is twined by compressible material then in principle.Guarantee that like this tightrope shape or the bar-like member be made up of compressible material can not stretch nocuously by being pressed in slit or the space.If tightrope shape or bar-like member at first can stretch, under inserting state, can shrink again so.Undesirable zone of tightrope shape or bar-like member filling meanwhile can appear not utilizing on space or slit.

In order to mat formation especially simply, at least two opposite flanks of an elbow-board have this plug connector that can at first an elbow-board be connected with respect to another vertical subsidence.In this regard, an elbow-board be arranged in parallel with respect to second.Particularly in this case, if the surface of elbow-board is a rectangle, leptoprosopy has this plug connector.Longitudinal side is preferred then to be constituted like this, makes to connect generally to finish around connecting rotatablely moving of seam.If an elbow-board is connected with the longitudinal side of second elbow-board by rotatablely moving on longitudinal side, leptoprosopy can enter in the respective cartridges or connector of an elbow-board that has paved equally so.It is the leptoprosopy of the elbow-board that paved equally in this regard.Can will pass slightly relatively by the interconnective elbow-board of leptoprosopy again according to the requirement of embodiment subsequently.Typically last this passing can be limited in less than 1/10 millimeter.In this manner, pass in the final position and compare very little with above-mentioned prior art.Correspondingly can shorten the required time of mating formation.What also want is, if elbow-board is at first nearer apart from wall, does not wish to comprise the method that the elbow-board of passing etc. is mated formation so especially.For mating formation by means of instrument, instrument almost can't insert elbow-board and between the walls then.In addition, if lug boss is very little because the room infiller panel will be close to superincumbent doorframe as far as possible, do not wish especially to pass.What have advantage then especially is elbow-board to be interconnected by the motion of sinking.Leptoprosopy for example can the disclosed mode of patent documentation DE 20008708 U1 produce, as long as disclosed thus connector relates to the words by sinking to connecting.

Tightrope shape or bar-like member can have substantial rectangular shape or foursquare diameter, so that can play the effect of flush sealing.

If width or diameter can reduce by compression, tightrope shape or bar-like member on the meaning of the present invention have desired elasticity or flexible.The solid material or the timber of metal are incompressible.

The size according to claim of elbow-board has advantage, because this size is easy to operation.Particularly the following size of 100cm has advantage, even also can transport because elbow-board is contained in the luggage case of motor bus then.

If have two tightrope shapes or bar-like member, these parts are preferred so constitutes like this, makes owing to the reset force of tightrope shape or bar-like member generation and can not leave the slit on the surface.Therefore what have advantage is, can cause quite little reset force with the tightrope shape or the bar-like member of the visible surface adjacency of elbow-board.Therefore elbow-board can wish the liftoff separately extruding of width.Reset force can suitably be adjusted by the material of selecting to form tightrope shape or bar-like member.As a supplement or select also can suitably to select cross section.Tightrope shape or the therefore preferred surface that on cross section, has greater than other tightrope shapes or bar-like member of bar-like member with surperficial adjacency.

In another embodiment, tightrope shape or bar-like member on one of alleged direction, the just for example vertical effect of playing two elbow-boards of pegging graft with the common surface of elbow-board.If particularly tightrope shape or bar-like member insert in the corresponding space, two elbow-boards are parallel and simultaneously vertical with shared connection seam.

The embodiment that two elbow-board grafting effects are played in the insertion of tightrope shape or bar-like member also can exist vertically or the contact surface of undercutting.Under situation about not stressing, also can realize connecting.In order for example to obtain the vertical contact surface with the surperficial parallel of two elbow-boards and vertical grafting with shared seam simultaneously, tightrope shape or bar-like member have the cross section of rectangle under the simplest situation.The connector of two elbow-boards that connect comprises the space that has rectangular cross section equally.If for example by in one plane moving with two elbow-board amalgamations a final position that exists above-mentioned two spaces to utilize rectangular cross section to be adjacent to each other so at last.They constitute a passage with rectangular cross section then.In this passage, can penetrate tightrope shape or bar-like member then.If tightrope shape or bar-like member are enough wide also enough high, two elbow-boards are pegged graft mutually so, and the gap can not occur.Play the contact surface vertical distribution of moulding grafting effect rationally.

In the prior art of alleged employing based on the connection of groove-embedding feather joint, except other plug connectors, also have elastic edge or sidewall, damaging reasonably connect so that can produce a kind of like this moulding, if particularly can appear in material quite firmly by moving in one plane.Particularly under the situation that connector for example is made up of HDF or this wood materials of MDF.The damage that can avoid this connector to be easy to occur in the above-described embodiment.Be connected mechanically highly stable because can produce contact surface vertical or undercutting.Even under situation for example, also can produce a kind of mechanically stable connection as the disclosed contact surface tilt distribution of patent documentation EP 00843763 B1, because elasticity of demand sidewall not, and plug connector projection quite far.

If have the protruding sidewall of the disclosed mode of patent documentation EP 00843763 B1, this sidewall can be shorter so, because it need not offset downward when connecting.Can corresponding saving material, because have cost advantage here.

In for example by the disclosed prior art of patent documentation DE 29823749 U1, the sidewall of two equal length is proposed.One of space of playing the grafting effect is in the inside of groove.The plug connector of respective bump is on the appropriate location of the second elbow-board embedding tenon.For position reason and only a small amount of projection of the plug connector of creating conditions and tilt distribution.Correspondingly the space is in the moulding of the inside of groove and definite size.Parallel with floor surface and simultaneously be connected the moulding of stitching vertical generation and reasonably be connected mechanically rather unstable.In present embodiment for example,, avoided this unstability if embodiment has the sidewall as the equal length of the groove of connector by vertical or steeper contact surface.

In order to insert the contact surface that bar-shaped or tightrope shape parts can reach undercutting in playing two elbow-board grafting effect embodiments, bar-shaped or tightrope shape parts have on cross section and for example shrink the position.Space on the connector that inserts bar-shaped or tightrope shape parts inside the grafting purpose has corresponding therewith cross section according to purpose.

In order bar-shaped or tightrope shape parts to be inserted in the space on the connector, so that two elbow-boards are pegged graft mutually, bar-shaped or tightrope shape parts preferably have even curface, so that the force of sliding friction that will produce during will pegging graft remains on not half.Bar-shaped or tightrope shape parts particularly are made up of the material of incompressible or less compression then, so that under the additional bar-shaped or tightrope shape parts situation that does not have from the teeth outwards to pack into, also can avoid the slit on the surface of elbow-board.Therefore material or its surface as bar-shaped or tightrope shape parts can be tetrafluoroethene according to purpose.HDF, MDF have suitable even curface equally, and therefore can preferably use equally.Rod metal or that have the metal surface has even curface, and therefore preferably can use.

For bar-shaped or tightrope shape parts being penetrated in the space on the connector and inserting then, bar-shaped or tightrope shape parts have advantage ground and narrow down at least one end.

Preferred this embodiment, insertions promptly bar-shaped or tightrope shape parts play the effect that two elbow-boards are pegged graft, the surface that has rectangle shape on the leptoprosopy of elbow-board.Elbow-board particularly interconnects by rotatablely moving on longitudinal side then.As long as need, the leptoprosopy of the elbow-board that has paved is passed subsequently relatively.At last bar-shaped or tightrope shape parts are inserted on the corresponding leptoprosopy: insert bar-shaped or tightrope shape parts for the purpose of pegging graft between the preferred leptoprosopy, here because distance is shorter.For with two corresponding grafting of elbow-board, bar-shaped or tightrope shape parts insert also corresponding weak point.

The embodiment with two elbow-board grafting effects is played in insertions bar-shaped or tightrope shape parts, can be on an elbow-board with prior art in disclosed connector be connected combination for producing a kind of non-adhesive.Especially preferably have for example elbow-board on rectangle shape surface, this elbow-board preferably constitutes on longitudinal side like this, and it can be connected with the second elbow-board non-adhesive by means of rotatablely moving, thereby very close to each other between the elbow-board.This embodiment has disclosed by patent documentation WO01/48332.Particularly this embodiment comprises the lower limb or the sidewall of rigid projections, has reached a kind of mechanically stable connection.On the another side of elbow-board, just particularly on the leptoprosopy, have a kind of embodiment then, the effect that two elbow-boards are pegged graft is played in insertions promptly bar-shaped or tightrope shape parts.At first first and second elbow-boards are interconnected by means of rotatablely moving.Subsequently with second elbow-board along on the adjacent elbow-board that shared connection seam is shifted onto with first elbow-board is connected.At last the second and the 3rd elbow-board is finally interconnected, method is that bar-shaped or tightrope shape parts are inserted through in the passage of the space formation on the corresponding connector.

According to the present invention can be veneer or combined tessera plate etc.It can be square or rectangular.It can be by timber, form as MDF or this wood materials of HDF, stone material, plastics, cement, pottery, metal etc.Therefore, by the present invention even a kind of floor of forming by stone material of mating formation of can floating.

The method of layer part or elbow-board of mating formation may further comprise the steps:

First elbow-board has been mated formation and has been finished.It has the lower wall of lateral projections.In the sidewall of projection, trough shaped void is arranged.But perhaps in this space or the depression position of inside, space be embedded in the tightrope (perhaps rod) of radial elastic distortion.Preferably by having the fibrous of very little elastic characteristic material, this fiber is coated by the such elastomeric material of for example rubber for tightrope or rod.Tightrope (perhaps rod) is because fiber and its length can not change.Second elbow-board utilizes a side, exactly preferably utilize its longitudinal side for example to tilt to be laid on first elbow-board, and be connected like this with the elbow-board of having mated formation by swinging in the shared elbow-board plane, make these elbow-boards with shared surperficial parallel and interconnect with vertical connection of shared seam by moulding.According to embodiment, also can be by an elbow-board is sunk to connecting with respect to another elbow-board.

Second elbow-board tilt is laid on the longitudinal edge of the elbow-board of formerly mating formation and by swing or sink to being connected in the above described manner with this elbow-board.

The another side exactly generally is that the leptoprosopy of elbow-board constitutes like this, if an elbow-board is sunk with respect to another, plug connector is rabbeted one by one.Under the situation of two alleged in the back corresponding location of elbow-board, under the state that sinks, formed a kind of grafting, with two elbow-boards with shared surperficial parallel and be connected the vertical mutual grafting of seam with shared.Two subsequently that the back is alleged elbow-boards are passed relatively.Meanwhile the embedding tenon of an elbow-board enters in the groove of another elbow-board.Two elbow-boards so also vertical interconnecting with the floor level.Need two elbow-boards under the situation that the back is alleged to insert the direction of the elbow-board that has paved, produce a kind of traditional groove-embedding feather joint thus.By this traditional groove-embedding feather joint, two elbow-boards are connected and grafting mutually by moulding with shared surface is vertical.

The edge of projection has the front groove of by the agency of equally on the leptoprosopy.Under the passing state of two elbow-boards, for example bar-shaped the or tightrope shape parts of round rubber mode are inserted through in the passage that the alleged elbow-board in above-mentioned groove and back constitutes.Size is particularly selected like this, makes between round rubber and the above-mentioned passage and leaves the gap.Insertions bar-shaped or tightrope shape parts are simple especially then.

Using basically can the square instrument that constitutes.Passage passes square body.Passage particularly begins on an end face, because this end face typically is uncovered during tool using.Passage finishes on the bottom surface, exactly is to finish on the other end of this pros' body.Passage preferably has the cross section of rectangle.This cross section longitudinal extension.Long side distributes from bottom to top.This instrument uses as the aid of mating formation of the elbow-board of mating formation.

Embedding tenon of projection on the bottom surface of instrument.This embedding tenon be arranged on passage below.This embedding tenon is (from the instrument finding) and/or narrow down forward downwards." back " or " backward " is meant the end face direction of the passage area institute adjacency that finishes on the bottom surface.

In one embodiment, the embedding tenon comprises preposition first area, and it is narrower than following Background Region.The almost twice that this narrower zone can be thicker zone is long.The front end of embedding tenon is compared and can further be narrowed down with narrow zone, to simplify operation described below, promptly packs in the seam slit that elbow-board by two combinations in the above described manner produces for the embedding tenon of the aid of will mating formation.Effect with the position that narrows down backward is can the aid of mating formation be pulled out from seam easily at last again.

The width of embedding tenon is at first outside, and particularly determines or forward size downwards like this, and it can be inserted at least in the slit of leaving on the surface of the elbow-board of two combinations.If the embedding tenon for example enough narrows down downwards, the embedding tenon can be packed in the above-mentioned slit by sinking from top so.If the embedding tenon correspondingly narrows down forward, this position that narrows down is inserted in the slit and like this embedding tenon is packed between the elbow-board so.Size is determined in the wideer zone of embedding tenon like this, if continue the embedding tenon is inserted between the elbow-board, makes the separately extruding of two elbow-boards thus.Be compressed by separately pushing the tightrope shape or the bar-like member that embed in the described groove when beginning.

Tightrope shape that preferably has basic rectangular cross section or the bar-like member preferably be made up of silicones are inserted in the passage of the aid of mating formation, and preferably insert from end face.Size is definite like this, and the width of tightrope shape parts is determined according to width of channel.In addition, the height of tightrope shape parts is determined according to width of channel.Leave less clearance between tightrope shape parts and the passage.

Tightrope shape parts can pass instrument without a doubt owing to the gap and expose from beneath in the back of embedding tenon again.In addition, the size of rectangular cross section is selected like this, and tightrope shape parts can not rotated in the inside of passage.

If tightrope shape parts are passed instrument, pack into and be between first and second elbow-boards in therebetween the slit in the zone that narrows down of embedding tenon utilization so.It for example is the beginning of the seam that will pack into of tightrope shape parts then.

Instrument has roller in one embodiment of the invention, so that utilize the roller instrument to move along connecting seam without a doubt.Otherwise instrument slides on elbow-board.There is the danger that may damage the elbow-board surface in this regard.

Aid is along being in that seam between the elbow-board is moved or moving if will mat formation, and meanwhile the embedding tenon is in the slit of seam, and elbow-board at first is subjected to separately extruding by the widened section of embedding tenon so.Meanwhile originally for example have circular cross section in the embedded groove and be compressed by the first bar-shaped or tightrope shape parts that rubber (round rubber) is formed.The widened section of embedding tenon is determined size like this, and the second tightrope shape parts of projection on the bottom surface of aid of mating formation are pressed in the connection seam without a doubt.Therefore preferably between the elbow-board of tightrope shape parts and separately extruding, leave little gap, become easy so that the insertion of tightrope shape parts is connected in the seam.That is to say that tightrope shape parts are generally packed into from above and connected in the seam.

If instrument continues along the seam walking, the connection seam of the aid back of mating formation so is because by the first tightrope shape of compression or the pressure sealing on a small quantity once more of bar-like member effect.Stitch base closed once more if connect, so tightrope shape parts since suitably between the size of determining and/or two elbow-boards moulding connect and/or the shape of friction connection is positioned.

In a kind of embodiment with advantage, instrument has on the rear end in connection sews on the roller that face rolls.Guarantee thus to reach smooth transition from the teeth outwards between elbow-board and the tightrope shape parts.

In one embodiment, the aid of mating formation is walked always and first is butted the place.Eccentric part from the side with butt between parallel insertion second elbow-board and the 3rd elbow-board.Have slit or passage shape space that the longitudinal extension eccentric part can be inserted in the inside for this reason.Eccentric part inserts like this, makes leptoprosopy and two elbow-board adjacency of eccentric part (eccentric part).Size is definite like this, and these parts can be inserted without a doubt.In one embodiment, between eccentric part and two elbow-boards, can leave the gap for this reason.

If eccentric part is inserted between two elbow-boards, utilize lever motion that eccentric part is rotated about 90o so.Be in the slit of seam expansion on the leptoprosopy surface between the second and the 3rd elbow-board thus.Bar-shaped or the tightrope shape parts that meanwhile insert in advance in butting are compressed.

Eccentric part can at one end be gone up crooked like this, and the end of this bending can be inserted in the side channel of one of two elbow-boards.Like this eccentric part is maintained with the position that 90o rotates.Otherwise guarantee that according to other modes eccentric part remains in the position of rotation.Can manually eccentric part be maintained.

Another tightrope shape parts that preferably have basic rectangular cross section are pressed into from above are between the second and the 3rd elbow-board in the groove on the plane of structure.If elbow-board is a rectangle, plane of structure is leptoprosopy particularly.Subsequently eccentric part is gone back to the home position again.Groove on the leptoprosopy roughly seals, and compression in advance meanwhile preferred be that the tightrope shape or the clavate parts of round rubber relax.Have the bar-shaped of preferred rectangular cross section or tightrope shape parts and be in positioning states between the second and the 3rd elbow-board now.Can connect and/or rub to connect by moulding and reach the location.

Eccentric part is pulled out from passage.The aid of mating formation walks on, until arriving next butting.In this manner, seam has from top visible tightrope shape parts, utilizes tightrope shape or bar-like member bound edge fully until elbow-board.

The fact shows, by means of the present invention's large-area elbow-board of can mating formation, and do not have the boundary seam on the layer of shop, floor.

In a kind of formation, the aid side of mating formation has the space.The aid walking like this during mating formation of mating formation, make the space with by plane of structure, particularly the seam that causes by leptoprosopy fixed in.The effect in space is tightrope shape or bar-like member can be embedded without a doubt like this from plane of structure, and these parts are arrived fully by means of the aid of mating formation pack into tightrope shape or bar-like member in the seam.

In of the present invention another constituted, the embedding tenon is such formation below the aid of mating formation, and this embedding tenon is narrowed down downwards on its whole length, thereby this embedding tenon can be packed into from above in the seam.If wall restriction side enters seam, this point has advantage especially.

In a kind of formation of the present invention, narrow down downwards or stepped contraction position with having in the groove of the surface adjacency of two elbow-boards.The aid (shuttle) of mating formation is definite like this according to this groove together with the embedding tenon below it, makes two elbow-boards only because in lower area, just applied pressure separately pushes in shrinking the zone at the position or the position that narrows down.

Even under the compression or relaxed state of the bar-shaped or tightrope shape parts that embedded that particularly exist in the round rubber mode, the embedding tenon of the aid of mating formation still preferably utilizes the gap to be in the connection seam inside of upper area.Mechanical load is not born in the top that reaches elbow-board thus, exactly, particularly stitches under the situation of pulling out from connecting at the aid of will mating formation.Otherwise the top can be subjected to undesirable damage and therefore influence outward appearance.

In of the present invention another constituted, there was the space in the seam inside between two elbow-boards, exactly, this space particularly be in above-mentioned narrow down position or stepped contraction position above.Connect in the seam if tightrope shape parts are packed into, fill up this space so, exactly, particularly because the flange of side projection on tightrope shape or bar-like member.Bar-shaped then or tightrope shape parts remain in the seam more reliably, exactly are because the moulding that obtains thus connects.Therefore, bar-shaped or tightrope shape parts are between two elbow-boards then especially reliably.

In the inexpensive especially embodiment of a kind of simplification of the present invention, the aid of mating formation that uses a kind of square basically to constitute.Embedding tenon of projection on the one side of square body.This embedding tenon constitutes in the above described manner.By this instrument elbow-board is expanded like this, bar-shaped or tightrope shape parts can be embedded in two connections seams between the elbow-board, and need not overcome friction.If this instrument is pulled out again, seam sealing slightly again so, thus bar-shaped or tightrope shape parts remain between two elbow-boards.

The simplification of aid of mating formation constitutes equally and can move along connecting seam.Back at the aid of mating formation can manually embed bar-shaped or tightrope shape parts in the zone of expansion.

Embed bar-shaped or tightrope shape parts on plane of structure or the leptoprosopy and should have at least and butt the length of cover size, so that obtain the surface sealed.If plane of structure is about 20cm, the lid dimensions length typically surpasses about 1mm.The aid of perhaps mating formation has suitable cutter sweep, and the inside embeds bar-shaped or tightrope shape parts, and can accurately suitably cut according to above-mentioned size.The aid of for this reason mating formation has for example passage, and the inside particularly can less clearance embed bar-shaped or tightrope shape parts.This passage matches with bar-shaped or tightrope shape parts on cross section.Cutting tool constitutes like this, makes it for example by pressing down such cut-out tightrope shape parts, obtains desired length.This cutting tool also can provide with the instrument that the aid of mating formation separates as itself.

The material of aid of mating formation can be the such metal of aluminium for example.But in order to make the aid of mating formation inexpensively, this instrument is preferably made by plastic pressure injection.

In a kind of formation of the present invention, mat formation aid or have quite wide roller on the end face in the above.As long as have roller on the bottom surface, this roller preferably obviously is wider than the roller of bottom surface.Above or the effect of this roller of end face be to sew on rolling in connection once more at last.If bar-shaped or tightrope shape parts have a small amount of undesirable projection from seam, can repair so.Effect is to exert pressure to tightrope shape parts, so that these parts roller that connects on the aid of mating formation in the seam of packing into exactly preferably is made of the particularly suitable metal hard material.

The mat formation preferred projection to a certain degree of roller of aid bottom makes the distance of mating formation between aid bottom and the elbow-board very little.This distance for example can only be several 1/10th millimeters in one embodiment, for example is 2/10mm.Advantage in this case is that the preliminary roller that the aid of mating formation only is used to lead is also made by hard metal.In any case this material should less compression, the distance of maintenance 1/10-2/10mm between the bottom that makes the aid of mating formation and the elbow-board surface.

If use square elbow-board, though so longitudinal seam and butt between as broad as long, paving method is identical in principle.Along a seam by means of the aid of the mating formation rubber of packing into.The seam of vertical distribution is utilized separately extruding and from top embedding tightrope shape parts of eccentric part therewith.

In a kind of formation of the present invention, have bonding adhesive, utilize them tightrope shape parts can be remained in the seam better.Bonding adhesive can be coated on the elbow-board by producer.In another embodiment, the bonding adhesive utilization aid of mating formation adds in the seam jointly.The aid of mating formation has advantage ground and has a corresponding magazine that is used for bonding adhesive or alite paste.By suitable conveying, before rubber is packed into, bonding adhesive is added in the bonding crack.Provide a kind of effectively especially like this by the just achievable high-quality of house ornamentation workman shop layer.

With the plane of structure or seam of above-mentioned seam vertical distribution on, can utilize the manual bonding adhesive that adds of corresponding instrument or collapsible tube equally.

Having advantage ground uses narrow side by the interconnective elbow-board that sinks.When sinking motion, at first keep for example gap greatly of 2.3mm between two narrow sides of elbow-board will interconnecting.The also only closed 0.5mm in this gap at last.This moving movement of being correlated with therewith less than 10telmm is used for tightrope shape parts are expressed between the connection seam that has on the surface.That is to say,, at first can embed 2mm wide tightrope shape or bar-like member so here if in this elbow-board, keep for example gap of 2.5mm on the surface.Subsequently an elbow-board is sunk with respect to another.The gap of original 2mm has dwindled for example 0.5mm in this regard.Last this bar-shaped or tightrope shape parts push at an easy rate and embed seam inside.

On longitudinal side, also can use the connector that has.Rubber here is installed in an identical manner.

The material of elbow-board almost can be arbitrarily.Present this material is made up of HDF or MDF in the composite floor board scope.Even but under the situation of pottery or stone floor brick, also can use connector without a doubt.

The specific embodiment

By embodiment the present invention is elaborated below.

Fig. 1 illustrates two interconnective elbow-boards 1 and 2.The elbow-board of composite floor board particularly in this case.The thick in this embodiment 8mm of shown elbow-board.Elbow-board 1 side has the dark groove of 2.5mm, groove width 1.9mm.This groove 3 comprises upper side 4 and downside 5.Upper side 4 thick 2.8mm.Downside 5 is longer than upper side 4.In interior outside in groove 3 zones, just with respect to the region memory of the downside 5 of upper side 4 projectioies in a space 6.Space 6 constitutes by the interface wall 7 of tilt distribution and the interface wall 8 of vertical distribution.The wall of tilt distribution opens wide at the direction upper hopper shape of floor surface 9.Utilize the angle that comprises one 15 degree with the vertical line of floor surface in this case.The wall 7 of tilt distribution plays the inherent regional effect to space 6 transition from groove 3.Constitute a wall of plug connectors 10 with the wall 8 of floor surface 9 vertical distribution.Plug connector 10 is on the open end at elbow-board 1 protruding side or edge 5.Plug connector 10 is in this case with respect to the bottom protrusion 0.7mm in space 6.Wall 8 constitutes a contact surface or plug surface, this face help elbow-board 1 parallel with 2 with floor surface 9 and with seam 11 vertical grafting.

Elbow-board 2 sides have embedding tenon 12.Under two elbow-board connection status, embedding tenon 12 is in the groove 3.The thickness of embedding tenon 12 cooperates like this with the width of groove, makes not have the gap up and down.The open end of embedding tenon 12 has the boundary limit 13 of tilt distribution below.Here the adjacent side 5 with groove 3 leaves distance.The effect on tilt distribution boundary limit 13 is that embedding tenon 12 can be penetrated in the groove 3 at an easy rate.Particularly space 13 is applicable to embedding tenon 12 by means of in the groove 3 of packing into around rotatablely moving of connection seam 11.

The following lobed flange 14 of embedding tenon 12.Constitute a space 15 that can produce thus by the bottom surface of milling elbow-board 2.Constitute the wall 16 and floor surface vertical distribution of transition between space 15 and the flange 14.Wall 16 constitutes a plug surface or contact surface simultaneously, this face with the interaction of interface wall 8 under, play effect parallel with floor surface 9 and that rationally peg graft with seam 11 vertical moulding.Because contact surface or plug surface 8 and 16 and floor surface 9 vertical distribution, thus with for example compare by the disclosed prior art of patent documentation WO 97/47834 A1, obtain between two elbow- boards 1 and 2 moulding especially reliably thus and reasonably peg graft.Because plug surface 8 and 16 moulding are reasonably pegged graft, further improved lower protrusion edge 5 and enough constituted regularly.Even elbow- board 1 and 2 is not to be connected by passing mutually an internal plane, downside 5 also can enough constitute regularly.Passing by in one plane connects to be had disclosed by above-mentioned patent documentation WO 97/47834 A1 equally.

For further improving parallel with floor surface and reasonably pegging graft with being connected seam 11 vertical moulding, plug surface 8 and 16 can be by undercutting.With respect to the slightly variation in several years of vertical distribution.That is to say that plug surface 8 inwardly tilts facing to space 6 then.Correspondingly plug surface 16 tilts to the direction in inherent space 15.Under connection status, plug surface 8 and 16 catches on then mutually.If can connect by in one plane passing, so this embodiment has advantage especially.For example the side 5 of projection can be bent downwardly far enough in this case, so that can connect by passing in one plane like this.For guaranteeing further that under the state of mating formation undesirable disengagement does not appear in the mutual passing by in one plane, plug surface 8 and 16 above-mentioned catching on mutually have advantage especially.Prevent downside 5 because vibration separates crooked by this catching on mutually.

The flange 14 of projection is demarcated by the wall 17 of tilt distribution facing to the open end of embedding tenon below the embedding tenon.Under inserting state, interface wall 17 and wall 7 parallel distributions.As shown in Figure 1, between inserting state lower wall 17 and wall 7, leave the gap.This gap can be several 1/10th millimeters.For example be 0.5mm in this case.

If plug surface 8 contacts with plug surface 16, the above-mentioned gap of 0.5mm appears between interface wall 17 and the interface wall 7 so.The for example thick slit of 2.5mm is left on the surface on floor simultaneously.That is to say, under inserting state, at first leave the gap between the elbow-board 1 and 2.This gap can make elbow-board interconnect, no matter plug surface 8 and 16 vertical in this embodiment still vertical distribution at least.Even can be by undercutting.This gap typically is 2/10 millimeter or bigger then.The shape and size of contact surface 8 and 16 are particularly depended in this gap according to the required size of purpose.The professional can determine the bottom line in this gap as the case may be by test, so that tilting, also can be connected under vertical or undercutting distribution contact surface 8 and 16 the situation.For this reason, also can have for example bigger gap of 1mm according to purpose.

Under inserting state, elbow-board 1 can be passed along connecting seam 11 with respect to elbow-board 2.This point wishes when mating formation, so that with the elbow-board final position of packing into.With for example compare by the disclosed prior art of patent documentation WO 97/47834 A1, this passing reaches especially easily.

Make moist and enter dust, pack into tightrope shape or bar-like member 18 for avoiding connecting in the seam 11 slit of leaving on two elbow-board surfaces 9.Tightrope shape or bar-like member 18 have rectangular cross section in this case and are equivalent to the shape in slit basically.Therefore tightrope shape or bar-like member 18 and elbow-board 1 flush with the plane with 2 surface 9 and are connected.

Preferred tightrope shape or bar-like member 18 slightly are wider than pack into the slit of tightrope shape or bar-like member, the inside.That is to say and slightly be wider than 2.5mm in this case.The degree of depth of tightrope shape or bar-like member 18 is equivalent to the thickness of side 4.That is to say, in this case the dark 2.8mm of tightrope shape or bar-like member and be in embedding tenon 12 above.Guarantee thus tightrope shape or bar-like member 18 unlikely enter excessively deeply to make in the slit on the surface 9 can not flush sealing.

Tightrope shape or bar-like member 18 are made up of silicone material in this case.This material has elasticity and therefore can compress.

Pack into the slit of tightrope shape or bar-like member 18, the inside is widened downwards.In this case, widening the position funnel-form distributes by wall 19 and 20.Widening the position can be very small.Several 1/10th millimeters enough.If tightrope shape or bar-like member 18 slightly are wider than the slit, reach the purpose that these parts extend in the zone in space by widening the position.Reach tightrope shape or bar-like member 18 thus and fixedly be in purpose in the slit, thereby prevent that tightrope shape or bar-like member from undesirably throwing off under the state of mating formation.

Like this can be in pavement process tightrope shape or bar-like member 18 be packed in the slit.But also can elbow- board 1 or 2 be connected with tightrope shape or bar-like member 18 by the manufacturing firm aspect.Because the compressibility of this material, compare with for example disclosed prior art of patent documentation WO 97/47834 A1 and can obtain desirable effect.Under the interconnective situation of elbow-board, can quite easily move along shared connection seam.Automatically produce under or the undercutting distribution situation vertical at contact surface 8 and to be connected with 16.

The difference of Fig. 2 embodiment and Fig. 1 embodiment is plug surface or contact surface 8 and 16 of undercutting particularly.Guarantee effectively especially that thus elbow-board 2 can not thrown off with elbow-board 1 if when elbow-board 2 spurred on the direction of arrow 21.Particularly under the situation of elastic sidewall 5, this embodiment has advantage especially.

The difference of Fig. 3 embodiment and Fig. 1 and Fig. 2 is to have another tightrope shape of packing between plug connector 8 and 16 or another bar-shaped parts 22.Play the effect of comparing gap between the increasing elbow-board with the embodiment of Fig. 1 and 2 thus, and needn't strengthen tightrope shape or bar-like member 18 on elbow- board 1 and 2 surfaces 9.In addition, tightrope shape or bar-like member 22 can also compensate the blockage effect that produces under the situation that elbow-board particularly made by wood materials.

If elbow-board adopts square surface, the embodiment of Fig. 3 on the so preferred leptoprosopy is because the blockage effect particularly here is very obvious.Wide influence of going up blockage effect wants littler.

If elbow-board is made up of wood materials, these elbow-boards generally at high temperature shrink so.If the elbow-board of wood materials is mated formation in the room of humidity, these elbow-boards generally can expand so.Therefore the embodiment of Fig. 3 preferably uses in the room that generally is heated.It here for example can be the sitting room of a dwelling house.

Be in tightrope shape between contact plate or elbow- board 8 and 16 or bar-like member 22 cross sectional dimensions and be generally less than tightrope shape or bar-like member 18 with floor surface 9 adjacency.The basic square of the cross section of tightrope shape or bar-like member 22 constitutes in this case.About 1mm * the 1mm of square size.

In the embodiment of Fig. 4, space 6 has another depressed part or space 23.Depressed part 23 and plug surface 8 adjacency.Tightrope shape or bar-like member 22 are in the depressed part 23 during grafting.Under uncompressed state, tightrope shape or bar-like member 22 parts are from another depressed part 23 projectioies.If elbow-board 2 is connected with elbow-board 1, so as shown in Figure 4, flange 14 at first all is pressed into tightrope shape or bar-like member 22 in the depressed part 23.

If subsequently elbow-board 2 is moved on the direction of elbow-board 1, tightrope shape or bar-like member 22 relax and enter between plug surface 8 and 16 so.Fig. 5 shows this state.The parts of this compression itself must be oval.This view of reason and actual conditions for general view are different.

In the embodiment of Fig. 4, the length of flange 12 is definite like this, makes elbow-board 2 by entering in the position shown in Figure 4 with respect to elbow-board 1 vertical subsidence.Arrow 24 illustrates motion.Subsequently elbow-board 2 is passed on the direction of elbow-board 1 along arrow 25.The moving movement of elbow-board 2 is very little and may be limited to several 1/10 millimeter.If moving movement is very short, can corresponding minimizing mat formation the required time so.This point is particularly compared with above-mentioned prior art, for example compares with the disclosed prior art of patent documentation WO 97/47834 A1.

A kind ofly in first step, can adopt square surface along the leptoprosopy of the preferred elbow-board of embodiment of arrow 24 vertical subsidences.The preferred then this connected mode of vertical face, wherein, by realizing connecting around connecting rotatablely moving of seam 11.It for example is this prior art that connects that produces by rotatablely moving of starting point with patent documentation WO 01/48332 A1 or patent documentation US 4,426,820.

If elbow-board 2 is passed on the direction of elbow-board 1 along arrow 25, situation shown in Figure 5 appears so.Also tightrope shape or bar-like member 18 (at last) to be packed into now and connect in the seam 11 and finish connection.For the situation from Fig. 4 reaches the situation of Fig. 5, only need elbow-board 2 is moved one to two millimeter.Compare with for example disclosed distance of the prior art of patent documentation EP 00843763 B1, this required segment distance is still quite lacked all the time.

Fig. 6 illustrates the elbow-board shown in Fig. 2 by rotatablely moving and elbow-board 1 grafting around connection seam 11.In this case, embedding tenon 12 is compared quite long with the embodiment of Fig. 5, thereby no longer may comprise the connection of at first sinking to moving according to arrow 24 (Fig. 4).Reaching the moulding of comparing perpendicular to the floor surface quite stable with Fig. 4 then reasonably is connected.

Tightrope shape or bar-like member 22 can have circular cross section.Diameter for example is about 2mm.Tightrope shape or bar-like member 22 local residing depressed parts 23 typically have the width than broad.For example width is 2mm, and the degree of depth is half width, can be 1mm.

If elbow-board comprises two tightrope shapes or bar-like member in the above described manner, tightrope shape or bar-like member 18 can be packed into from the surface especially simply so, method is at first to utilize the elasticity separately extruding of corresponding instrument with contrary tightrope shape in lip-deep slit or bar-like member 22.Then under the state of separately extruding, the width in slit particularly is wider than the tightrope shape in the slit of will packing into or the width of bar-like member 18 on the surface.Can especially simply tightrope shape or bar-like member 18 be embedded then.Removal tool subsequently is because tightrope shape or bar-like member 22 expansion elbow-boards 1 are near elbow-board 2.As long as reach dynamic balance, because this moving that tightrope shape or bar-like member 22 expansions produce will stop.Can not leave the slit then on the surface.

Tightrope shape on the surface 9 or bar-like member 18 are dustproof and moistureproof then.

Fig. 7 illustrates tightrope shape or 18 1 kinds of formations with advantage of bar-like member of packing into from the surface.This tightrope shape or bar-like member 18 both sides on cross section have a kind of barb 26 and 27.In order to compress tightrope shape or bar-like member 18, the space 28 that on the bottom surface, has arch especially effectively from the side.In addition, tightrope shape or bar-like member 18 for example can have fiber 29 in inside, to avoid bulking effect.Therefore fiber 29 is made up of not dilatable material, according to Fig. 7 by as this compressible material coating of silicones.

The visible surface 30 of tightrope shape under the state or bar-like member 18 of packing into can constitute on the plane, so that can utilize elbow-board surface 9 planar surface encloses.

Fig. 8 illustrates elbow- board 1 and 2, and wherein, the embedding tenon 12 of elbow-board 2 is inserted in the groove 3 of elbow-board 1.The side 5 of projection has the space 30 of rectangle on the cross section in the above.Embedding tenon 12 has the space 31 of rectangle on the cross section below.Two spaces 30 are identical with 31 width.If the embedding tenon 12 of elbow-board 2 inserts in the groove 3 of elbow-board 1 fully, they overlap each other so, thereby do not have the slit on shared connection seam 11. Space 30 and 31 constitutes a passage, and bar-shaped or tightrope shape parts are inserted in the inside, so that elbow-board 1 is parallel to surface 9 with elbow-board 2 and pegs graft perpendicular to being connected seam 11.Elbow-board 2 passed on the direction of elbow-board 1 be easy to the position that reaches shown in Figure 8, because need not to overcome the plug connector of projection.Under state shown in Figure 8, also be easy to elbow-board 2 is passed along shared connection seam with respect to elbow-board 1 because elbow-board only with surface 9 vertical grafting.

The difference of Fig. 9 and Fig. 8 is bar-like member 32, its last insertion in the passage that is made of space 30 and 31.Bar-like member 32 is at least almost the same wide with the width of space 30 and 31, so that make the slit that does not occur on the surface 9 connecting on the seam 11.Form the material of bar-shaped or tightrope shape parts 32 and preferably form then, the slit to occur on the surface 9 of avoiding connecting seam 11 by less or incompressible material.Therefore metal or wood materials can be used as material and use.

If elbow- board 1 and 2 constitutes the surface of a sealing in the mode shown in Fig. 8 and 9, so for example for the outward appearance reason, on other sides, have this connector equally according to purpose, constitute the surface of a sealing.Particularly according to purpose, the leptoprosopy of elbow-board utilizes square surface to constitute so then, finishes final grafting by inserting rod 32.Preferred this then by means of stitching rotatablely moves finishes the connector of connection around connecting on longitudinal side.Meanwhile, on the surface 9 between two elbow- boards 1 and 2, there is not the slit then equally.That is to say that seam 11 is closed.Figure 10 illustrates this embodiment.Although contact surface 8 and 16 tilt distribution are still can be by means of the connection that rotatablely moves so that lack the gap.The side 5 preferred rigidity of projection constitute, to guarantee elbow- board 1 and 2 stable pegging graft under inserting state.

If with Fig. 8 and 9 selectable a kind of embodiments in elbow- board 1 and 2 constitute like this, make on the surface 9 that connects seam 11 and leave the slit, in this slit, insert the bar-shaped or tightrope shape parts of for example forming 18 according to purpose so by silicones or rubber.Bar-shaped or tightrope shape parts 32 according to purpose by tetrafluoroethene or have flexible and the material of smooth surface is formed.Can quite easily bar-shaped or tightrope shape parts 32 be inserted in the passage that is made of space 30 and 31 then, exactly, particularly under the such situation about constituting of the leptoprosopy of elbow-board.That is to say, compare occur on the leptoprosopy littler with longitudinal side with the counteractive frictional force of insertion generation.

Can have other shapes on the bar-like member cross section.Like this can be with this elements constrict.Space 30 and 31 cross section constitute according to purpose is corresponding then, thereby have the contact surface 8 and 33 and 34 and 35 of undercutting.Figure 11 illustrates this embodiment.

For not allowing the people notice peculiar position when inserting, bar-like member has circular cross section.As shown in figure 12, space 30 and 31 corresponding semicircle formations.

If at least one side becomes wedge angle, the insertion of rod 32 is easy especially so.Preferred then two sides become wedge angle, utilize which end of rod to penetrate in the passage so that allow user or customer need not to be concerned about.

Figure 11 illustrates the situation that space 30 and 31 narrows down to open end.The bar-like member 32 of subordinate has the contraction position, forms the contact surface of undercutting.If the sidewall 4 of groove 3 is identical with 5 length, so this embodiment has advantage especially, because these sidewalls quite approach and therefore be easy to bending.

Figure 12 illustrates a kind of embodiment, and wherein, the plug connector 36 of elbow-board 2 can be packed in the space of elbow-board 1 by vertical subsidence.Two plug connectors 36 and 37 have semicircular space 30 and 31, and pole 32 is inserted for last purpose of pegging graft in the inside.On connection seam 11, there are not slit or space.Can connect with respect to elbow-board 1 vertical subsidence elbow-board 2, and need not subsequently elbow-board to be moved.

The connector of Figure 12 if having no basis on the whole side of an elbow-board, what so still have advantage especially is, on an elbow-board with square surface, has a kind of embodiment on longitudinal side, wherein, by finishing connection around connecting rotatablely moving of seam 11.For example this is consulted this connector shown in Figure 10.On leptoprosopy, has embodiment then according to Figure 12.

If such elbow-board with another on longitudinal side by around shared connections that rotatablely move that is connected seam, the while also can be connected with the adjacent elbow-board of having mated formation by leptoprosopy so, and need not this elbow-board is inserted in the final position at last.Be final grafting, only need then rod 32 is inserted in the passage that is made of space 30 and 31.

Space 30,31 and 37 and the shape of plug connector 37 can be different with embodiment shown in Figure 12.This point only need consider that shape constitutes like this, makes it can carry out the grafting of desirable no binder at last on alleged direction.

By the invention provides the following method that is used to connect two elbow-boards.Elbow-board 1 is assembled like this with elbow-board 2, makes space 30 and 31 constitute a passage.Connector constitutes like this, and elbow-board is pegged graft on first direction then.In this passage, insert bar-like member subsequently.Connector constitutes like this, makes two elbow-boards both vertical also parallel with shared surface 9 with shared surface 9 then and stitch 11 vertical grafting with being connected simultaneously.

Parts 32 also can be made up of the elastomeric material with best high reset force, can be fixed in one of two spaces 30 or 31 by producer then.Particularly tightrope shape parts are made up of silicones or hard PVC then.

The diameter of the bar-shaped or tightrope shape parts on the meaning particularly of the present invention is 0.5mm at least, preferably 1mm at least.If bar-shaped or tightrope shape parts have rectangular cross section, the length of rectangular-shaped piece and width preferably are at least 0.5mm so, particularly preferably are at least 1mm.In addition, the bar-shaped or tightrope shape parts on the meaning particularly of the present invention are parts independently, in one embodiment as the sort of parts that can paste with elbow-board.Meanwhile physical characteristic is constant.This then bar-shaped or tightrope shape parts are distinguished to some extent with this situation in one embodiment, are about to cream or similar material and are coated on the elbow-board under the state of fluid ability and subsequently cream are hardened having.

Figure 13 and 14 illustrates the further expansion of Figure 4 and 5 illustrated embodiment.

Figure 13 illustrates a connector on the elbow-board of having mated formation 1 longitudinal side with section.Elbow-board 1 is in the lobed lower wall 5 of longitudinal side upper side.Be in the protruding sidewall 5 is the groove shape space 6 with groove depression portion 23.Depressed part 23 in inside, space is embedded in tightrope 22.Tightrope comprises fiber or the line of being made up of the material with low elasticity characteristic 29, is coated by rubber or silicones.Tightrope 22 is because fiber and length is constant.Second elbow-board 2 utilizes its longitudinal side to tilt to be connected with elbow-board 1, and enters shared elbow-board plane 9 by swing.Elbow-board 2 is connected like this with the elbow-board 1 of having mated formation thus, makes it parallel with shared surperficial 9 and reasonably interconnect with shared seam 11 vertical moulding.

The embedding tenon 12 of elbow-board 2 is very short in this case can be connected with elbow-board 1 in the above described manner by sinking elbow-board 2.Still elbow-board 2 being passed on the direction of elbow-board 1 after the sinking, so that arrive situation shown in Figure 13.Embedding tenon 12 can be longer, because connect with subsequently swing and can be connected basically by the inclination on longitudinal side without a doubt.

The second elbow-board 2a tilts to be connected on the longitudinal edge of the elbow-board 1 of at first mating formation, and is connected in the above described manner with it by swing.

Elbow-board 2 shown in Figure 14 and the leptoprosopy of 2a constitute like this, if elbow-board 2a is suitably sunk with respect to another elbow-board 2, plug connector 14 and 10 are rabbeted successively.Under the situation of in the end alleged two elbow-boards 2 and the corresponding location of 2a, after being sunk, elbow-board 2a had a kind of grafting, and two elbow- boards 2 and 2a and shared surface 9 is parallel and be connected seam 11 vertical mutual grafting with shared.Subsequently will last alleged pass relative of two elbow-boards 2 with 2a.Meanwhile, the embedding tenon 12 of elbow-board 2a enters in the groove 3 of another elbow-board 2.As shown in figure 14, therefore also perpendicular to the ground connection of two elbow-boards 2 and 2a.Two elbow-boards 2 and the 2a that will mat formation at last when needing pass on the direction of elbow-board 1, also produce a kind of traditional groove-embedding feather joint thus between elbow-board 1 and elbow-board 2 or 2a.By this traditional groove-embedding feather joint, two elbow-boards 1 are reasonably pegged graft with shared surface 9 vertical moulding with 2a mutually with 2 and 1.

The rib 5 of projection has the above-mentioned groove 6 that has depressed part 23 equally on elbow-board 2 leptoprosopy.Depressed part 23 is the boundary to be in the plug connector 10 that raises up on salient rib or sidewall 5 open end.Under the close state of two elbow- boards 2 and 2a, the tightrope shape parts 22 that have circular cross section among Figure 14 insert by above-mentioned depressed part 23 and locate in the passage that last alleged elbow-board 2a zone thereon constitutes.Downwards the plug connector 14 of the elbow-board 2a that extends help to provide the inside insert-as among Figure 14 with shown in the section-passage of tightrope shape parts 22.Size can be selected like this, makes between tightrope shape parts 22 and the above-mentioned passage and leaves the gap, and tightrope shape parts 22 insert especially easily then.

Use now in Figure 15 a with lateral view and in Figure 15 b with the instrument shown in the front elevation drawing 40.Matrix 41 rectangle basically constitutes.Passage 42 passes rectangular body 41.Passage 42 is in end face 43 (front) beginning, because this end face typically can not be capped during tool using 40.Passage is 44 end in the bottom surface, exactly are to finish near the other end 45 (back) of rectangular body 41.As seeing from Figure 15 b, passage 42 has rectangular cross section.Preferred passage is widened to end face 43, inserts tightrope shape parts 18 to simplify.The longer face 45a of rectangular cross section and the parallel sidewalls of instrument 40 just distribute from bottom to top.The size of passage 42 cross sections cooperates with tightrope shape parts 18 like this, and these parts can not rotated in the inside of passage 42.Like this, in the embodiment shown, owing to cooperate the tightrope shape parts 18 actual 90o that can not rotate to insert in the passage 42.

Instrument 40 uses as the aid of mating formation of mat formation elbow- board 1,2,2a.The mat formation help of aid of utilization is packed tightrope shape parts 18 in the seam 11 that is made of elbow- board 1 and 2 into.

Embedding tenon 46 of projection on the bottom surface 44 of instrument 40.This embedding tenon 46 is arranged on the inside of passage 42.As from Figure 15 b is clear see, embedding tenon 46 downward (from instrument 41 direction findings) narrows down.

In one embodiment, embedding tenon 46 comprises first forefoot area 47 that is narrower than following rear region 48.Narrower regional 47-as seeing from Figure 15 a-preferably longer, that is to say to be almost thicker regional 48 two double-lengths, so that simple operations.The front end 49 of embedding tenon 46 is compared and can further be narrowed down with narrow regional 47, so that the embedding tenon of the aid of will mating formation is packed in the slit of the seam 11 that exists owing to the elbow- board 1,2 that connects in the above described manner.Embedding tenon 46 has the portion of narrowing down 50 backward, is to mat formation aid 41 particularly to finally pulling out under elbow-board 1, the 2 harmless situations in order to guarantee better from seam 11.

The width of embedding tenon 46 is at first outside, exactly particularly determines so downwards or forward to make size in the slit of the seam 11 that leaves at least on its elbow-board that can be inserted in two connections 1,2 surfaces.If embedding tenon 46 for example enough narrows down downwards, embedding tenon 46 can enter in the above-mentioned slit 11 by sinking from top so.If embedding tenon 46 narrows down forward, this portion 47,49 that narrows down can insert in the slit 11 so, and like this embedding tenon 46 is packed between the elbow- board 1,2.

The widened section 48 of embedding tenon 46 is determined size like this, if embedding tenon 46 continues to insert between the elbow- board 1 and 2 and widened section 48 is suitably entered between elbow- board 1 and 2, makes two elbow-boards 1 thus and opens extruding in 2 minutes.By this separately extruding, space 6 depressed parts, the 23 interior tightrope shape parts 22 that originally embed the existence of elbow-board 1 groove shape are compressed.

With preferably by silicones forms, preferably have be similar to rectangle or exactly preferably mat formation the passage 42 of aid 41 from end face 43 insertions to the tightrope shape of the youthful and the elderly's cross section or bar-like member 18 in.Size is definite like this, and the width of tightrope shape parts 18 is determined according to the width of passage 42.In addition, the height of tightrope shape parts 18 is determined according to the height of passage 42.Leave the gap between tightrope shape parts 18 and the passage 42, thereby tightrope shape parts can pass from passage 42.

Tightrope shape parts 18 can pass from instrument owing to the gap, and expose near the aft bulkhead 45 on the bottom surface 44 of embedding tenon 46 back.The size of basic rectangular cross section is selected like this, if tightrope shape parts 18 are passed or are pulled through from passage 42, makes them can be in passage 42 inner rotation.

If tightrope shape parts 18 pass instrument 40, the zone that narrows down of embedding tenon 46 utilization is in the slit 11 between first elbow-board 1 and second elbow-board 2 so.The aid 40 of mating formation particularly is in the seam 11 of the tightrope shape parts of will packing into when beginning then.

Mat formation aid or instrument 40 has roller 51 and 52 in one embodiment of the invention, utilizes roller 51,52 that instrument 40 is walked without a doubt along connecting seam 11.Otherwise instrument 40 slides on elbow-board 1 and 2.Exist the danger that may damage elbow- board 1 and 2 surfaces in this regard.

Aid 40 moves or walks along being in seam 11 between elbow- board 1 and 2 if mat formation, and meanwhile embedding tenon 46 is in the slit of seam 11, and elbow- board 1 and 2 at first is subjected to separately extruding by the widened section 48 of embedding tenon 46 so.Meanwhile originally embedded groove or the depressed part 23 first interior tightrope shape parts 22 are compressed.The widened section 48 of embedding tenon 46 is determined size like this, and the second tightrope shape parts 18 of projection on the bottom surface 44 of aid 40 of mating formation are pressed in the connection seam 11 without a doubt.This size is preferred to be determined like this, meanwhile makes between the elbow- board 1 and 2 of tightrope shape parts 18 and separately extruding and leaves little gap, becomes easy so that make tightrope shape parts 18 insert to connect in the seam 11.That is to say that tightrope shape parts 18 are generally packed into from above and connected in the seam 11.

If instrument 41 continues along seam 11 walkings, the connection seam 11 of aid 40 back of mating formation so is owing to pass through the pressure sealing on a small quantity once more of the first tightrope shape parts, 22 effects of compression.If connect seam 11 base closed once more, so tightrope shape parts 18 since suitably between the size of determining and/or two elbow- boards 1 and 2 reasonable the and/or rational shape that rubs of moulding be fixed.

Have in the embodiment of advantage one, instrument 40 is being sewed on the roller 51 that face rolls near having on the rear end of end wall 45 in connection.Guarantee thus elbow- board 1 and 2 and tightrope shape parts 18 between from the teeth outwards smooth transition.This situation does not illustrate in Figure 15 a and 15b.

In one embodiment, the aid 40 of mating formation is walked always and first is butted 60 places, as from Figure 16 was seen of elbow- board 1,2,2a is shown with vertical view.The back tightrope shape parts 18 of aid 40 of mating formation have entered in the seam 11.

Among Figure 19 with the eccentric part shown in the section 70 from the side with butt between 60 parallel insertion second elbow-boards 2 and the 3rd elbow-board 2a.Preferably have slit or preferred passage shape space 71 (as shown in figure 17) on elbow-board 2 and/or elbow-board 2a, the eccentric part 70 of longitudinal extension can be inserted in the inside for this reason.Eccentric part 70 inserts like this, makes leptoprosopy and two elbow-boards 2 and the 2a adjacency of eccentric part (eccentric part).Size is definite like this, and these parts can be inserted without a doubt.In one embodiment, for helping this between eccentric part 70 and two elbow- boards 2 and 2a, can leave the gap.

If eccentric part 70 is inserted between two elbow-boards, shown in arrow among Figure 17 72, utilize the lever 73 shown in Figure 19 that eccentric part 70 is rotated about 90o so.Be between second elbow-board 2 and the 3rd elbow-board 2a leptoprosopy lip-deep slit 60 expansions shown in Figure 16 thus.The consequence of rotating as 90o is, inserts the tightrope shape parts 22 that butt in the passage that 60 inside have for this reason in advance and is compressed.Figure 18 illustrates the position that eccentric part 90o rotates.

Eccentric part 70 can be crooked like this on the end of lever 73, and the end 74 of this bending can be inserted in the side channel of two elbow-boards 2 or 2a.Like this eccentric part 70 is maintained with the position that 90o rotates.Otherwise guarantee that according to other modes eccentric part 70 remains in the position of rotation.

For ease of eccentric part 70 is inserted in the passage 71 that has or the enough wide slit for this reason, preferably these parts have the portion of narrowing down 75.Insert in passage 71 that for this reason has or the enough wide slit that for this reason has in the zone that at first this is narrowed down.

Another tightrope shape parts 18 with preferred basic rectangle or long cross section can be pressed into from above and be between second elbow-board 2 and the 3rd elbow-board 2a in the slit on the leptoprosopy 60.Can select to insert from this side, particularly this locational size is definite like this, makes tightrope shape parts 18 have the gap as shown in figure 18 and is in the seam.

If elbow- board 1,2,2a have square surface, plane of structure 60 is leptoprosopy particularly.

Subsequently eccentric part 70 is gone back to the home position again.Groove on the leptoprosopy 60 roughly seals, and the tightrope shape parts 22 of compression in advance meanwhile are lax.Tightrope shape parts 18 with preferred rectangular cross section are in the positioning states between second elbow-board 2 and the 3rd elbow-board 2a now.Can connect and/or rub to connect by moulding and reach the location.Particularly because moulding connects, but also is to reach the location because strength connects according to Figure 17, is easy to pressurized then and is in the seam because have the tightrope shape parts 18 of preferred long cross section.

Then eccentric part 70 is pulled out from passage 71 or corresponding slit.The aid 40 of mating formation walks on, until arriving next butting.In this manner, seam 11,60 (or slit) has from top visible tightrope shape parts 18, utilizes tightrope shape or bar-like member 18 bound edges fully until elbow- board 1,2,2a.

The fact shows, by means of the present invention's large-area elbow-board of can mating formation, and do not have the boundary seam on the layer of shop, floor.

In one embodiment, aid 40 sides of mating formation have the space.Aid 40 walking like this during mating formation of mating formation, make the space with by leptoprosopy 60, particularly the seam that causes by leptoprosopy fixed in.The effect in space is tightrope shape or bar-like member can be embedded without a doubt like this from leptoprosopy 60, and these parts are arrived fully by means of the aid of mating formation pack into tightrope shape or bar-like member 18 in the seam 11.

In of the present invention another constituted, embedding tenon 46 is such formation below the aid of mating formation, and this embedding tenon is narrowed down downwards on its whole length, thereby this embedding tenon can be packed into from above in the seam.If these wall restriction sides enter seam, this point has advantage especially.

In a kind of formation of the present invention, narrow down downwards or stepped contraction 76 positions with the seam 11 of surface 9 adjacency of elbow- board 1,2,2a.Instrument 40 is definite like this according to having this seam of shrinking position 76 together with the embedding tenon below it 46 then, makes two elbow- boards 1 and 2 only because in lower area, just applied pressure separately pushes in shrinking the zone at the position 76 or the position that narrows down.

Even under the contraction or relaxed state that particularly have the bar-shaped or tightrope shape parts 22 that circular cross section embedded, the embedding tenon 46 of aid 40 of mating formation still utilizes the gap to be in the inside that connects seam 11, with upper area, just shrink the top relevant of position 76 thus.Mechanical load is not born in the top that reaches elbow- board 1 and 2 thus, exactly, particularly will mat formation aid 40 under connection seam 11 situations of pulling out.Otherwise the top of elbow- board 1 and 2 can be subjected to undesirable damage and therefore influence outward appearance.

In of the present invention another constituted, there was space 77 in seam 11 inside between two elbow- boards 1 and 2, exactly, this space particularly be in above-mentioned narrow down position or stepped contraction position 76 above.Connect in the seam 11 if tightrope shape parts 18 are packed into, fill up this space 77 so, exactly, particularly because the flange 78 of side projection on tightrope shape or bar-like member 18.Bar-shaped then or tightrope shape parts 18 remain in the seam 11 more reliably, exactly are because the moulding that obtains thus connects.Therefore, bar-shaped or tightrope shape parts 18 are between two elbow- boards 1 and 2 then especially reliably.

In a kind of formation of the present invention, mat formation aid 40 in the above or end face have the quite wide roller 80 of particularly being wider than wheel or roller 51 and 52.That is to say that this roller preferably obviously is wider than the roller of bottom surface.Above or the effect of this roller 80 of end face be to roll connecting on the seam 11,60 once more at last.If bar-shaped or tightrope shape parts 18 have a small amount of undesirable projection from seam 11,60, can repair so.Effect is to exert pressure to tightrope shape parts 18, so that these parts roller 52 and 80 that connects on the aid 40 of mating formation in the seam 11,60 of packing into exactly preferably is made of the particularly suitable metal hard material.

The mat formation preferred projection to a certain degree of roller 51,52 of aid 40 bottoms makes the distance of mating formation between aid bottom and the elbow- board 1,2 very little.This distance for example can only be several 1/10th millimeters in one embodiment, for example is 2/10mm.Advantage in this case is that the preliminary roller 51 that the aid 40 of mating formation only is used to lead is also made by hard metal.In any case this material should less compression, the distance of maintenance 1/10-2/10mm between the bottom that makes the aid 40 of mating formation and elbow- board 1,2 surfaces.

Figure 20 illustrates another embodiment of the present invention, and exactly, at least one side of elbow- board 2 and 2a can interconnect by sinking.This is meant elbow-board 2a and elbow-board 2 keeping parallelisms of having mated formation, and can sinks for purpose of connecting.Position that can keeping parallelism during the sinking.If elbow-board 2a sinks to a certain extent, it is on the plane identical with elbow-board 2, the flange 14 to lower convexity is in the space that is open upwards 6 so then.Elbow- board 2 and 2a and surface 9 are parallel and is connected grafting mutually by moulding then with seam is vertical.The plug connector that makes progress on the end of lower protrusion edge 5 is outwards slight curving then, particularly helps this point by having the diagonal brace 90 that advantage ground is in below the plug connector.

At first on the surface 9 of elbow- board 2,2a, leave for example slit of 2.5mm.If now with one for example the wide tightrope shape parts of 2.2mm insert in this slit, so because there is the gap, so can embed without a doubt.After with the embedding of tightrope shape parts, elbow-board 2 is passed about 0.5mm on the direction of elbow-board 2, here so that make quite short embedding tenon 12 enter in the groove 3 and such and surperficial 9 vertical grafting.The moving movement of this several 1/10th mm is used for tightrope shape parts are squeezed between the connection seam that has on the surface 9.

The connector of Figure 20 can use on whole side.Because a little less than the grafting quite on the vertical direction, only on leptoprosopy 60, use so preferably include the connector of the embedding tenon 12 in the quite short embedded groove 3.

Figure 21 illustrates one embodiment of the present invention, from top 9 bar-shaped or tightrope shape parts 18 preferred these embodiments under the situation between two elbow- boards 1 and 2 of packing into only.If these tightrope shape parts not with shown in mode pack between two elbow- boards 1 and 2, two preferred so mutual grafting of elbow-board make it leave less gap so.

Elbow- board 1 and 2 shown in Figure 21 constitutes like this, make seam 11 above leave the slit.(several 1/10th millimeters) bar-shaped or tightrope shape parts 18 preferably slightly are wider than in this slit.If should be bar-shaped or tightrope shape parts be pressed into from above in the slit, be easy to so then these parts are pressed in the slit.Guarantee that thus the top prevents water seal.Moisture issues also is avoided.

In the embodiment shown, the slit shown in Figure 21 reaches the top of embedding tenon 12 always.But for the processing reason, this point is also nonessential for formation of the present invention according to purpose.

For guaranteeing bar-shaped or tightrope shape parts 18 accurately and reliably are between elbow- board 1 and 2, these parts connect by moulding and remain in the desired position.In this case, inside, slit has at least one, preferred two elevated flanges 95 that are connected with elbow-board separately.These elevated flanges not only are used for above-mentioned moulding and connect, and also constitute the contraction position simultaneously in the inside of groove.Groove shrinks the advantage that the position has, can be by means of instrument (aid of mating formation) with two elbow-boards with the separately extruding of mode of by the agency of, and the edge on can damaging surface 9.

With section bar-shaped or tightrope shape parts 18 as using are shown among Figure 22 and 23 on the elbow-board as shown in Figure 21 1 and 2.Its side has at least one, preferred two spaces 96.Space 96 like this with flange 95 actings in conjunction of projection, reach desired moulding thus and connect.

On the bottom surface of bar-shaped or tightrope shape parts 18, preferably has a groove 97.Bar-shaped thus or tightrope shape parts 18 have can be easy to enough two posts of compression.Can especially simply bar-shaped or tightrope shape parts 18 be pressed in the slit that has on the seam 11 then.

Bar-shaped or tightrope shape parts 18 bottom surface upper hopper shapes narrow down.Guarantee to be easy to bar-shaped or tightrope shape parts 18 are packed in the slit by the surf zone 98 of corresponding tilt distribution.

Bar-shaped or tightrope shape parts 18 shown in Figure 22 are preferred by quite hard, but also have enough flexible material, for example are made up of hard PVC material.

Embodiment shown in preferred Figure 23.Here, if the lower area 100 of bar-shaped or tightrope shape parts 18 by forming as this quite hard material of hard PVC material, upper area 99 is by for example forming as this softer elastomeric material of flexible PVC material.The zone of hard material guarantees bar-shaped especially effectively or tightrope shape parts are between elbow- board 1 and 2 in accordance with regulations reliably.The part of being made up of quite soft zone 99 guarantees that bar-shaped or tightrope shape parts 18 also can be compressed here.Even guaranteeing bar-shaped or tightrope shape parts 18 so also can enter under the slightly narrow situation in slit in the slit between two elbow- boards 1 and 2 fully.Upper area 99 is squeezed with having advantage then and is between two elbow-boards, enters to prevent humidity, dust etc.

Figure 24 illustrates matrix 201, and it and cover plate 202 constitute an elbow-board jointly.Particularly has the space 200 that is used to penetrate cable.Figure 25 is illustrated in a kind of rectangular cross section that uses on the stair.
