Description

地板和锁定系统 Floor and locking systems

本发明涉及一种机械连接地板(floorboard)的锁定系统以及具有这种锁定系统的地板。 The present invention relates to a mechanical connection of flooring (FloorBoard) and a locking system having such a locking system floor.

技术领域 FIELD

本发明特别适用于木质材料制成的地板,在正常情况下,所述木质材料地板具有木芯并被机械地连接。 The present invention is particularly applicable to floors made of wood material, under normal circumstances, the wood floor having wood core material and mechanically. 将在下文描述的现有技术以及本发明的目的和特性针对在该领域的应用,尤其是在长边和短边被机械连接在一起的矩形镶木拼花地面板。 The prior art as well as objects and features of the present invention will be described hereinafter for the application in the field, especially in the long and short sides are connected together mechanically rectangular parquet parquet panels. 本发明特别适用于浮式地板,也就是可以相对于基底移动的地面板。 The present invention is particularly applicable to floating floor, i.e. can be moved relative to the base panel. 然而应该强调的是,本发明也适用于现有所有类型硬地面板(hardfloor),例如单一的木制地面板、具有层状芯或胶合板芯的木制地面板、具有饰面板表面和木纤维芯的地面板、薄层叠压制品地面板、具有塑料芯或类似芯的地面板。 However, it should be emphasized that the present invention is also applicable to all types of existing hard panels (hardfloor), for example, be a single wooden panel, having a lamellar core or plywood core to the wooden panel, having a wood veneer surface and fiber the core of the panel, the panel sheet laminated article having a plastic core or similar core of the panel. 本发明当然也可以被用于其它类型的能够由切削刀具机加工的地板,例如胶合板或刨花板的底层地板。 The present invention may also be used of course, can be processed by the cutting tool machines of other types of flooring, for example chipboard or plywood subfloor. 即使不是优选的,地板也可以在安装后被固定在基底上。 Even though not preferred, the floor may be mounted on the substrate after fixing.

背景技术 Background technique

主要由于其卓越的铺设特性、连接强度和连接质量,在短时间内机械连接占了很大的市场份额。 Mainly due to its superior laying properties, joint strength and quality of connection, mechanical connection in a short time accounted for a large market share. 即使将在下文更详细介绍的专利文献WO9426999中的地板和商标名为Alloc的地板与传统的胶贴地板相比具有很大的优点,然而也希望对其进行进一步的改进。 Even if the Patent Document WO9426999 described in more detail below in the floor and the floor trademark name Alloc and compared with conventional floor stickers great advantage, but also want to be further improved.

机械连接系统不仅对层制品地板的连接而且对木制地板和组合地板的连接都非常方便。 The system of mechanical connection is connected not only of laminate floors but also wooden floors and floor connection combinations are very convenient. 这种地板在表面、芯部和背侧可以包括大量不同材料。 This floor surface, and the back portion of the core may include a number of different materials. 如下所述,这些材料也可以被包含在连接系统的不同元件内,例如条(strip)、锁定元件和舌榫(tongue)。 As described below, these materials can also be connected to the different elements contained within the system, such as strip (Strip), the locking member and the tongue (tongue). 例如专利文献WO9426999或WO9747834介绍了一种复合条(integratedstrip)的方案,该方案提供一种水平连接,也涉及一种提供垂直连接的舌榫,然而在形成机械连接时由于对地板材料进行机加工,引起由材料造成的成本问题。 E.g. Patent Document WO9426999 or WO9747834 describes a composite article (integratedstrip) of the program, which provide a horizontal connection, also relates to a method of providing a vertical tongue and groove connection, however, when a mechanical connection of flooring since machining , causing the cost of problems caused by the material.

为了实现最佳功能,例如15毫米厚拼花地板应该具有宽度近似等于地板厚度的条,也就是15毫米。 For optimal function, for example, 15 mm thick parquet floor should have a strip width is approximately equal to the thickness of the floor, i.e. 15 millimeters. 利用大约3毫米的舌榫,浪费的数量大约是18毫米。 Using a tongue of about 3 mm, amount of waste is approximately 18 mm. 地板的正常宽度大约是200毫米,因此大约浪费9%的材料。 Normal width of the floor is about 200 mm, about 9% of the material and therefore waste. 通常,如果地板选用昂贵的材料制造,如果它们厚或如果它们格式小,材料浪费引起的成本通常非常大,从而每平方米地板的连接延米将是很大的。 In general, if the choice of expensive flooring materials, if they are thick or if their small format, the cost of waste materials are usually caused by very large, so that each square meter of floor connections will be great.

当然,如果使用被分别制造的铝条形式的并在工厂就被固定在地板上的条,材料浪费的数量可以被减少。 Of course, if the form of aluminum are respectively manufactured in the factory and are fixed to the floor strip, the number of material waste can be reduced. 此外与被机加工并由芯组成的条相比,铝条可以导致更好和更低廉的连接系统。 Further the strip is machined by a core composition compared to aluminum can result in better and cheaper connection system. 然而铝条具有下述缺陷,即需要可观的投资,必须对工厂进行大量的重建以便改造传统的生产线,从而生产具有这种机械连接系统的地板。 However, aluminum has a drawback that requires considerable investment, the plant must be rebuilt in order to transform a large number of traditional production lines to produce such a flooring with mechanical joint system. 在现有技术中,铝条的优点是无需改变地板的起始规格。 In the prior art, the advantages of the aluminum without changing the specifications of the starting floor.

当涉及通过对地板材料进行机加工所生产的条时,情况相反。 When it comes to the floor through the material strip produced by machining, the opposite situation. 从而地板的规格必须被调整,从而具有足够的材料形成条和舌榫。 Whereby floor specification must be adjusted so as to have sufficient material forming the strip and the tongue. 对于层制品地板来说,经常需要改变所使用装饰纸的宽度。 For laminate floors, it is often necessary to change the width of the decorative paper used. 所有这些调整和变化也要求对生产设备进行耗资巨大的改造和巨大的产品适应(productadaptation)。 All these adjustments and changes also require costly production equipment and great product transformation to adapt (productadaptation).

除了上述与不希望的材料浪费、生产成本以及产品适应相关的问题之外,条还具有如下缺点,也就是对运输和安装期间的损害非常敏感。 In addition to the above-mentioned waste and unwanted materials, production costs and product adaptation-related problems outside the bar also has the disadvantage that is very sensitive to damage during transport and installation.

总而言之,对提供一种低成本同时保持现有良好性能的机械连接具有很大的需求,所述良好性能是指铺设、提起(takingup)、连接质量和强度。 In summary, a great need for mechanical provide a low cost while maintaining good performance of the conventional connector, the good performance of the laying means, lift (takingup), connection quality and strength. 利用现有技术,不能获得低成本同时又没有降低强度和/或铺设功能的地板。 The prior art, can not be obtained at low cost while not reducing the strength of the floor and / or laying function. 本发明的一个目的是提出一种技术方案,其能够降低成本,同时保持强度和性能。 An object of the present invention is to propose a technical solution, which can reduce costs while maintaining the strength and performance.

本发明起源于公知的地板,所述地板具有芯部、前侧面、后侧面和相对的连接边缘部分,其中一个连接边缘部分被形成为舌榫槽,该舌榫槽由上、下唇缘确定,并具有一底端,另一个连接边缘部分被形成为舌榫,所述舌榫在其自由外端具有向上部分。 The present invention is originated in the known floor, said floor having a core, a front side, rear and opposing side edge portions of the connection, wherein a connecting flange portion is formed as a tongue groove, the tongue groove defined by upper, lower lip and having a bottom end connected to the other edge portion is formed as a tongue, said tongue at its free end having an outer portion upwardly. 舌榫槽具有一带开口、一内部和内锁定表面的底切部分形状。 Having a tongue groove along the opening, and an inner bottom surface of the inner locking portion cut shape. 至少下唇缘部分与地板芯部整体形成,舌榫具有一锁定表面,当两个类似的地板机械相连时,该锁定表面与邻接地板上舌榫槽的内锁定表面相互配合,从而它们的前侧面在同一表面平面(HP)上,并在垂直的连接平面(VP)上相遇。 At least a portion of the lower lip is formed integrally with the floor of the core portion, a tongue having a locking surface, when two similar floor mechanically connected to the upper surface of the locking tongue and the floor adjacent to the surface of the locking groove with each other so that their front side on the same surface plane (HP), and meet in a vertical plane of connection (VP). 专利文献WO9627721、DE-A-1212275、和JP3169967介绍了这种技术,将在下文对此进行详细介绍。 Patent Document WO9627721, DE-A-1212275, and JP3169967 describes this technique, which will be described in detail below.

然而在此之前,有关地板和机械连接地板的锁定系统的一般技术作为本发明的背景技术将被介绍。 However, before the relevant art flooring and mechanical locking systems in general connected to the floor as a background art of the present invention will be described.

长边的连接边缘部分4a和4b以及短边的连接边缘部分5a和5b可以被机械地连接在一起,无需在图1c中箭头D所示方向上使用胶水,从而在连接平面VP(如2c所示)接触(meet),从而在它们被铺设状态,使它们的上侧在一共同的表面平面HP(如图2c所示)内。 4a and 4b are connected to an edge portion and a flat VP (2c are connected as an edge portions 5a and 5b may be connected mechanically together the short sides, without the use of glue in FIG. 1c direction of the arrow D, so that the long sides in connection shown) contacting (Meet), so that they are laid state, in a common surface plane HP (shown in FIG. 2c) on the inner side thereof.

在所示实施例中,也就是专利文献WO9426999中的一个示例中(图1~3所示),地板1具有工厂安装平面条6,其沿整个长边4a延伸,所述条6由可弯曲的弹性铝板制成。 In the illustrated embodiment, i.e. one example in Patent Document WO9426999 (FIGS. 1 to 3), a factory-installed floor panel 1 has a planar strip 6 which extends along the entire long side 4a, the strip 6 can be bent by a made of resilient aluminum sheet. 条6向外延伸,在连接边缘部分4a超出连接平面VP。 Bar 6 extending outwardly beyond the connecting portion 4a connected edge plane VP. 根据所示实施例,条6可以被机械地附着在地板上,或采用胶水或其它方式使其附着在地板上。 According to the embodiment, the strip 6 can be mechanically attached to the floor, or using glue or otherwise allowed to attach to the floor. 如该文献所述,作为在工厂能够被附着在地板上的条的组成材料,也能够使用其它条材料,例如其它一些金属板材、铝或塑料。 The composition of the material strip of the document, as in a factory can be attached to the floor, it is possible to use other strip materials, such as sheet of some other metal, aluminum or plastic. 如专利文献WO9426999所述和如WO9966151所述和所示,例如通过适当地机加工地板1的芯,条6可以与地板1整体形成。 As described and shown in Patent Document WO9426999 and WO9966151, such as the, for example core 1, the strip 6 may be integrally formed with the floor 1 by appropriately machining the floor.

本发明适用于这样的地板,也就是条或至少一部分条与芯整体地形成,本发明解决了这种地板的连接、拆卸和生产中的特殊问题。 The present invention is applicable to the floor, or at least a portion of the article is strip formed integrally with the core, the present invention solves the problem connected to this particular floor, disassembly and production. 地板芯无需但是最好由同样材料制造。 But no need to floor the best core made of the same material. 然而条总是与地板整体形成,也就是其应该被形成在地板上或在工厂被安装。 However, Article always is integrally formed with the floor, that is, it should be formed on the floor or be installed at the factory.

在符合上述专利文献WO9426999和WO9966151的公知实施例中,条6的宽度大约是30毫米,厚度大约是0.5毫米。 In embodiments consistent with the above-described Patent Document WO9426999 and WO9966151 well known, the width of the strip 6 is about 30 mm and a thickness of about 0.5 millimeters.

类似的但是较短的条6'沿地板1的一个短边5a被设置。 Similar but shorter strip 6 'along one short side 5a of a floor is provided. 一部分突出到连接平面VP之外的条6被形成的具有沿整个条6延伸的锁定元件108。 Having a portion projecting out of the plane of connection to VP, the locking member 6 is formed of 1086 extending along the entire strip. 锁定元件108在其下部具有面对连接平面VP的可操作锁定表面10,高度例如是0.5毫米。 The locking member 108 has in its lower plane VP operably linked facing locking surface 10, for example, a height of 0.5 mm. 在铺设时,该锁定表面10与锁定槽14相互配合,该锁定槽14被制造在邻接地板1'的相对长边的连接边缘部分4b的底侧面3上。 In laying, this locking surface 10 and the locking groove 14 cooperate with each other, the locking groove 14 is fabricated on the bottom side of adjacent floor 1 'of the opposite long side edge portion 4b of the connector 3. 沿短边的条6'配备有一相应的锁定元件108',相对短边的连接边缘部分5b上具有相应的锁定槽14'。 Along the short side strip 6 'is provided with a corresponding locking element 108' having a corresponding locking groove 14 on the connecting edge portion 5b of the opposite short sides'. 锁定槽14、14'离开连接平面VP的边缘形成用于与锁定元件的可操作锁定表面10相互配合的可操作锁定表面10'。 The locking groove 14, 14 'away from the edge connector is operable plane VP is formed with a locking element operative locking surface 10 cooperating locking surface 10'.

为了在垂直方向(图1c中的方向D1)上机械连接长边和短边,地板1沿其一个长边(连接边缘部分4a)和其一个短边(连接边缘部分5a)形成有一横向敞开的凹入部分或舌榫槽16。 For its one long side (connection edge portion 4a) and its one short side (the connection edge portion 5a) formed in the vertical direction (direction in FIG. 1c D1) is mechanically connected to the long and short sides, the floor panel 1 along a transverse open tongue or groove recessed portion 16. 在上侧该舌榫槽被连接边缘部分4a、5a的上唇缘限定,在下侧被各自的条6、6'限定。 In the upper side of the tongue groove is connected to the edge portions 4a, 5a of the upper lip defines a lower side by respective strips 6, 6 'is defined. 在相反的连接边缘部分4b、5b上具有上凹入部分18,其被与凹入部分或舌榫槽16(嵌图2a)相互配合的锁定舌榫20限定。 Connecting the opposite edge portions 4b, has a concave portion 18 on the upper 5b, which are locked to each other with a recessed portion or tongue groove 16 (FIG insert 2a) cooperating tongue 20 is defined.

图1a~1c显示在地面U上两个这样的地板1、1'的两个长边4a、4b如何通过向下倾斜并围绕靠近表面平面HP和连接平面VP之间交叉点的中心C转动而能够被彼此连接在一起,同时地板被保持的彼此接触。 FIG. 1a ~ 1c show two such U on the ground floor 1 'of the two long sides 4a, 4b and by how downwardly and rotates about the center C close to the surface plane HP and the connection point of intersection between the plane VP They can be connected to each other, while the floor is held in contact with each other.

图2a~2c显示地板1、1'的短边5a、5b通过快速咬合(snapaction)被连接在一起。 FIG. 2a ~ 2c show short floor 1, 1 'edges 5a, 5b are connected together by flash nip (snapaction). 长边4a、4b可以利用两种方法被连接在一起,在铺设第一行地板后,当长边4a、4b已经被连接后,短边5a、5b的连接主要通过快速卡合进行。 Long sides 4a, 4b can be connected together by two methods, after the laying of the first row in the floor, after the long sides 4a, 4b have been connected, the short sides 5a, 5b are connected together mainly by flash card.

如图1a~1c所示,当一块新地板1'和已经被铺设的地板1沿它们的长边部分4a、4b被结合时,如图1a所示,新地板1'的长边部分4b被压向已经被铺设的地板1的长边部分4a,从而锁定舌榫20插入凹入部分或舌榫槽16。 FIG. 1a ~ 1c, when a new floor panel 1 'and the floor has been laid along a portion of their long sides 4a, 4b when bound, shown in Figure 1a, the new floor panel 1' is a long side 4b pressed against the floor has been laid long side 4a 1, so that the locking tongue 20 is inserted into the concave portion or the tongue groove 16. 如图1b所示,地板1'然后向下倾斜向地面U移动。 As shown in FIG 1b, the floor panel 1 'is then moved downwardly to the ground U. 锁定舌榫20完全进入凹入部分或舌榫槽16,同时,条6的锁定元件108卡进槽14内。 The locking tongue 20 enters completely the recess or tongue groove part 16 while the locking bar 6 into the card slot 108 of the inner member 14. 在向下倾斜移动期间,锁定元件108的上部9是起作用的,用于将新地板1'引导到已经被铺设的地板1。 During the downward movement, the locking member 108 of the upper 9 is active, a new floor for 1 'to guide the floor panel 1 has already been laid.

在图1c所示的连接位置,地板1、1'在D1和D2两个方向上沿它们的长边4a和4b被锁定,但是地板1、1'可以沿长边在纵向(也就是D3方向)彼此相对移动。 In the connection position shown in FIG. 1c, the floor 1 and 1 'in two directions D1 and D2 along their long sides 4a and 4b are locked, but the floor 1, 1' can be moved in the longitudinal direction of the longitudinal D3 (i.e. ) relative to one another.

图2a~2c显示通过使新地板1'基本上水平地朝向已经被铺设的地板1移动而如何可以将地板1、1'的短边5a和5b在D1和D2两个方向上连接在一起。 FIG. 2a ~ 2c show 'and how can be moved substantially horizontally toward the floor has been laid floor 1, 1' are connected together by the short side of the new floor panel 1 5a and 5b in both directions D1 and D2. 这种连接通常是在上述地板1'的长边已经被连接之后进行的,如图1a~1c所示,在一邻接行内通过向内向已经被铺设的地板1倾斜而进行连接。 This connection is usually performed after the connection has been in the long side of the floor panel 1 'side, as shown in Figure 1a ~ 1c, in an adjacent row has been laid by inward to an inclined floor connection. 在图2a所示第一步骤中,凹入部分16的斜角表面和锁定舌榫20相互配合,从而作为短边5a、5b结合的直接结果,迫使条6'向下。 In a first step shown in FIG. 2a, beveled surfaces of the concave portion 16 and the locking tongue 20 cooperate so that as a direct result of the short side 5a, 5b bonded to force bar 6 'downwardly. 在最终连接阶段,当锁定元件108'进入锁定槽14'内时,条6'向上卡合,从而锁定元件108'和锁定槽14'上的操作表面10、10'彼此啮合。 In the final stage is connected, when the locking member 108 'into the locking groove 14' within that article 6 'engages upwardly, so that the locking member 108' on the operating surface 10, 10 'and the locking grooves 14 engage with each other.

通过重复执行图1a~1c和图2a~2c所示操作,整个地板可以沿所有连接边缘被铺设,而无需胶水。 2a and 2c the operation shown in FIG. ~, The entire floor can be laid without glue by repeatedly performing FIGS. 1a ~ 1c are connected along all edges. 因此上述类型的现有技术地板可以被机械地连接,首先使长边向下倾斜移动,通过使新地板1'沿已经铺设的地板1的长边(方向D3)水平移动,当长边被锁定后,使短边向下倾斜移动,然后卡合在一起。 Thus the prior art of the type described above may be mechanically connected to the floor, so that the long side is first moved downwardly, the longitudinal (direction D3) horizontally by moving the new floor panel 1 'in the already laid floor panel 1, when the long side is locked after the downward movement of the short sides, then snapped together. 在接头没有被损害时,地板1、1'可以被反过来拆卸,然后再次铺设。 When the joint is not compromised, floor 1, 1 'can be disassembled in turn, then laid again. 这些铺设技术的一部分也适合于本发明。 Some of these techniques are also suitable for the laying of the present invention.

为了达到最佳功能,允许轻易地铺设和再次拆卸,在被连接之后,现有技术的地板应该沿其长边能够处于这种状态,也就是锁定元件的操作锁定表面10与锁定槽14的操作锁定表面10'之间出现最小的间隙。 For optimal function, allows easy laying and disassembled again, after being connected, the prior art flooring should be capable along the long side in this state, that is, the operating member 10 and the locking surface of the locking groove 14 of the operation the smallest gaps between the locking surface 10 '. 然而在地板之间的实际对接头处,在靠近地板上侧面(也就是表面平面HP)的连接平面VP上不需要间隙。 However, in practice of the joint between the floor, no gap in the connecting plane VP close to the upper side surface of the floor (i.e. the surface plane HP) of. 在这种位置,必须将一个地板压靠在另一个地板上。 In this position, you must be a floor on the other pressed against the floor. 专利文献WO9426999中更详细地介绍了这种间隙。 Patent Document WO9426999 describes such a gap in more detail. 当邻接地板的长边彼此压靠时,操作锁定表面10、10'之间的间隙是0.01~0.05毫米。 When the gap length of the floor adjacent to one another against the pressure side, the operation locking surface 10, 10 'is between 0.01 and 0.05 mm. 该间隙便于锁定元件108进入锁定槽14,同样也便于锁定元件108离开锁定槽14。 The gap 108 facilitates the locking member into the locking groove 14, the locking member 108 is also easy to leave the locking groove 14. 然而如上所述,在地板之间的连接处不需要间隙,该该位置,表面平面HP和连接平面VP在地板的上表面上交叉。 As described above, however, the connection between the floor space is not required, the position of the surface plane HP and the connection plane VP intersect at the upper surface of the floor.

连接系统确保在连接一任意边后在锁定位置沿连接边移动,从而可以采用对三个基本方法进行变型的多种方式进行铺设:使长边倾斜,使短边卡合;使长边卡合,使短边卡合;使短边倾斜,使两个地板向上倾斜,使新地板沿已经被铺设的地板的短边移动,最后使两个地板向下倾斜。 Connection system ensures movement along the connection edge in the locked position after an arbitrary connecting edges, so that the three basic methods can be a variety of ways using variant laying: the inclination of the long sides, engagement of the short Comb; of the long edge card engagement , engagement of the short Comb; short-side inclination, the two upwardly inclined floor, so that the new floor has been laid is moved in the short sides of the floor, and finally the two downwardly inclined floor.

最常用和最安全的方法是首先使长边向下倾斜,地板彼此锁定在一起。 The most common and safest method is to first make the long side downward, locked together with one another floor. 然后在锁定状态下,向第三个地板的短边移动,从而短边可以卡合。 Then in a locked state, moves toward the short side of the third floor, so that the short side can be engaged. 也可以沿一边也就是沿长边或短边铺设,与另一个地板卡合。 It may be along one edge i.e. along the long or short side laying, together with the other board. 然后在锁定状态进行移动,直到另一侧与第三个地板卡合在一起为止。 Then moves in the locked state, until the other side of the third board together so far. 这两种方法要求至少卡合一边。 Both methods require at least engages the side. 然而也可以无需快速卡合而进行铺设。 However, it need not be laid quickly engages. 第三种方法是第一地板的短边首先向内向第二地板的短边倾斜,该第二地板的长边已经与第三地板连接在一起。 The third method is the short side of the first floor to the first short side is inclined inward of the second floor, the second floor of the long side has been connected to the third floor. 在连接之后,使第一地板和第二地板稍微向上倾斜。 After the connection, the first floor and the second floor is slightly inclined upward. 第一地板沿它的短边向上倾斜地移动,直到第一和第三地板的上连接边缘彼此接触为止,此后,两个地板向下连接地倾斜。 A first movable floor is inclined upwardly along its short side until the first and third floors are connected with each other until the edge contacts, thereafter, two downwardly inclined connecting to the floor.

对于厚度大约为7毫米的层制品地板以及厚度大约0.6毫米的铝条的地板来说,为上述地板和它的锁定系统在市场上非常畅销。 For a thickness of about 7 mm and an aluminum laminate flooring strip about 0.6 mm thickness of the floor, the floor above and its locking system is very popular in the market. 同样,对图4a和4b所示的专利文献WO9966151中的地板进行改变也是非常成功的,然而已经发现,该技术并不特别适用于由木纤维基材料制成的地板,特别是由大量木质材料或胶粘叠层木质材料形成的拼花地板。 Also, Patent Document WO9966151 shown in FIGS. 4a and 4b changes the floor is very successful, it has been found, however, that the technique is not particularly useful for a floor made of wood-fiber-based material, in particular of a large number of wooden materials wood material or glued laminated parquet formed. 这种公知技术不适用于这种类型产品的一个原因就是由于对边缘部分进行机加工以形成具有必要深度的舌榫槽,从而引起大量材料被浪费。 This known technique does not apply to a cause of this type of product is due to the edge portion is machined to form a tongue groove having the necessary depth, thereby causing large amount of material is wasted.

如图5a和5b所示,英国专利文献GB-A-1430423介绍了一种公知的用于地板的机械锁定系统。 Figures 5a and 5b, British Patent Document GB-A-1430423 describes a known mechanical locking system for a floor. 该系统是一种舌榫-槽连接,在舌榫槽一侧上延伸的凸缘上配备有一额外保持钩,在舌榫上侧形成有相应的保持脊(holdingridge)。 The system is a tongue - groove connection, provided with an extra holding hook on the flange which extends in the groove side of the tongue, the tongue is formed on the side corresponding holding ridge (holdingridge). 该系统要求配备有钩的凸缘具有可观的弹性,在不破坏地板的连接边缘情况下,不能拆卸。 This system requires a flange provided with a hook having considerable flexibility in the connection without damaging the edge of the floor, can not be removed. 更紧的装配使制造困难,连接的几何形状导致大量材料浪费。 The tighter the manufacturing assembly is difficult, the geometry of the connection results in substantial material waste.

专利文献WO9747834介绍了一种具有不同机械锁定系统的地板。 Patent Document WO9747834 describes a mechanical locking system has a different floor. 这种用于锁定地板长边的锁定系统(在该文献中的图2~4、11和图22~25)被这样设计,从而通过连接和倾斜运动进行安装和拆卸。 Such a locking system for locking the floor of the long sides (in FIG. 2 of this document and FIG. 4, 11 ~ 22 ~ 25) are designed such that mounting and dismounting of connecting and tilting movement. 用于锁定地板短边的锁定系统(图5~10)被这样设计,从而通过彼此相向推动利用卡合而连接在一起,但是当地板短边没有被破坏或在某些情况下没有被伤害时,该锁定系统不能被拆卸。 For locking the locking system of the short side of the floor (5 to 10) is designed such that face each other are connected together by pushing by the engagement, but not not been damaged or injured in some cases when the local short side plate the locking system can not be disassembled.

专利文献WO9747834介绍了一些地板,通过转动或卡合,这些地板被固定和拆卸(WO9747834中的图2~4以及附图14a~14c),在这些地板的一边上具有槽,条在所述槽下方突起并延伸超出两个地板上侧在连接时的连接平面之外。 Patent Document WO9747834 describes some of the floor, or by rotating the engagement, these floors are fixed and detached (FIGS. 2 to 4 and in figures 14a ~ 14c WO9747834) and having a groove on one side of the floor, said groove strip downward projection connected to and extending beyond the plane of the floor on both sides of the connection outside. 该条与地板相反边缘上所形成的互补部分相互配合,从而两个相同地板可以被连接在一起。 Strip floor opposite the upper edge portion complementary to cooperate formed so that the two identical floor panels may be connected together. 这些地板的共有特性是地板上舌榫的上侧和槽的相应上界面是平面,并与地板的上表面平行。 These characteristics of total floor tongue is on the floor on a respective side of the interface and the groove are plane and parallel to the upper surface of the floor. 一方面利用舌榫上侧的锁定表面,另一方面利用下唇缘的上侧或槽下方的条,获得阻止连接平面被横切地拉开的地板连接。 On the one hand by the locking tongue upper surface, on the other hand the use of the lower lip or strip below the groove side, to prevent the connection plane is obtained pulled apart transversely of the floor connection. 这些锁定系统也具有缺点,它们要求延伸到连接平面之外的条部,导致在形成槽的连接边缘内也造成材料浪费。 These locking systems also have the disadvantage that they require to extend out of the plane of the connecting strip portion, resulting in grooves formed in the connecting edge is also wasted material.

为了机械连接不同类型地板,提出多种建议,其中当使用木纤维和木基地板材料时,浪费材料少,能够以有效方式进行生产。 In order to mechanically connect different types of floor, various proposals made, wherein when using wood fiber board and wood base material, less material waste, can be produced in an efficient manner. 专利文献WO9627721(在附图部分的图5a~5b)和JP3169967(在附图部分的7a-7zb)介绍了两种类型的造成材料浪费小的卡合连接,但是它们具有这样的缺点,也就是地板的拆卸不容易。 Patent Document WO9627721 (in the drawing portion in FIG. 5a ~ 5b) and JP3169967 (in figures 7a-7zb portion) describes two types of waste material bonded connection causes a small card, but they have the drawback, i.e. floor removal is not easy. 此外在这些系统中,不能使用大的锁定角,以便降低被拉开的风险。 Further, in these systems, you can not use the large locking angle, so as to reduce the risk of being pulled apart. 接头的几何形状不利于要求材料具有可观变形量的卡合,在制造公差方面必须适应大表面部分必须彼此准确调整的要求。 The geometry of the joint is not conducive to a considerable amount of deformation of a material having a required engagement, must adapt to the requirements of surface portions must be accurately adjusted to each other in terms of manufacturing tolerances. 这些彼此接触的表面部分也使地板在锁定状态下彼此相对移动更困难。 These surface portions contact each other so that the floor is also in a locked state relative to each other more difficult.

如图8a和8b所示,专利文献DE-A-1212275介绍了另一种公知的系统。 As shown in Patent Document DE-A-1212275 describes another known system shown in Figure 8a and 8b. 这种公知的系统适用于由塑料制成的运动地板,不能利用用于形成锐利的底切部分的大盘形切削工具制造。 Such known systems for sports floor made of plastic can not be utilized for the formation of a sharp cutting tool tape-shaped undercut manufacturing. 当不使用具有极大弹性的材料时,也就是当被拉开时,围绕底切部分的上下唇缘可以极大地变形,这种公知的系统不能被拆卸。 When no material having great elasticity, i.e., when opened, can be greatly deformed around the upper portion of the lower lip of the undercut, this known system can not be disassembled. 如果希望高强度的连接,这种类型连接不适合于木基材料制造的地板。 If high strength connection, this type of connection is not suitable for the manufacture of wood-based material flooring.

FR-A-2675174介绍了一种用于陶瓷瓷砖的机械连接系统,所述瓷砖具有互补的相反边缘,当使用分离的弹簧夹时,该弹簧夹被安装成彼此间隔一定距离,并用于抓住邻接瓷砖边缘部分上的凸条(bead)。 FR-A-2675174 describes a mechanical connection system for ceramic tiles, said tiles having complementary opposite edges, when isolated using a spring clip, the spring clip is mounted at a distance from one another, for grasping and ridges (a bead) on the edge portion abutting tiles. 该连接系统被设计成不能通过转动而被拆卸,如图10a详示,特别是图10b。 The connection system is not designed to be detached by rotation, shown in detail in Figure 10a, in particular, FIG. 10b.

DE 20001225U1介绍了另一种屈服的系统。 DE 20001225U1 yield introduce another system. 然而这种现有结构非常敏感,由于下唇缘已经被锁定槽削弱,具有很大缺点。 However, this conventional structure is very sensitive, since the lower lip has been weakened by the locking groove, it has a great disadvantage.

DE19925248介绍了具有向上指向锁定元件的系统。 DE19925248 describes a system having upwardly directed locking element.

如上所述,现有技术的系统既具有缺点又具有优点。 As described above, prior art systems have advantages and disadvantages with both. 然而没有一种系统适用于具有锁定系统的地板的合理生产,该锁定系统的生产技术最优化、浪费材料最少,铺设和拆卸功能最佳,其可以被用于在铺设状态下具有高质量、强度和功能的地板。 However, no A system suitable for rational production of flooring having a locking system, the locking system is optimized production technology, a minimum waste of material, laying and disassembly function best, which may be used in a high quality state laying, strength and the function of the floor.

此外,根据下文描述,本发明的优点和特征变得更加清楚。 Further, according to the following description, features and advantages of the present invention will become more apparent.

在结合附图介绍本发明具体和优选实施例之前,将介绍发明基本概念、所要求的强度和功能。 Before particular embodiments in conjunction with the accompanying drawings and described embodiments of the present invention, preferably, the basic concept of the invention will be described, and the intensity of the required function.

本发明适用于具有第一对平行边和第二对平行边的矩形地板。 The present invention is applicable to a first pair of parallel sides and a second pair of parallel sides of the rectangular floor. 为了简化描述,在下文将第一对边称作长边,第二对边称作短边。 To simplify the description, hereinafter referred to as the first side of the long sides, short sides referred to the second pair of sides. 然而应该指出的是,本发明也适合于正方形地板。 However, it should be noted that the present invention is also suitable for square floor.

高连接质量高连接质量是指在锁定位置时地板之间在水平和垂直方向上的紧配合。 High connection quality high connection quality refers to a tight fit between the floor when in the locked position in the horizontal and vertical directions. 在不承担负荷或在正常承载情况下,连接边缘之间无需大的可视间隙或各处间隙在数量上没有很大差别,就能连接地板。 Without incurring load or load under normal circumstances, the connection between the edge without large visible gaps or without gaps around vary widely in number, can be connected to the floor. 在高质量的地板中,连接间隙和间隙在数量上的差异应该分别不大于0.2和0.1毫米。 In the high floor, the difference in the gap and the gap is connected in number should be no more than 0.2 respectively and 0.1 mm.

围绕连接边缘向上倾斜通常,应该能够使地板的长边向上转动,从而拆卸地板。 Generally upwardly inclined connecting edge, the floor should enable long sides turned upwards, so that the floor around the disassembly. 由于在初始位置的地板用紧连接边缘连接,通过上边缘彼此接触并在连接边缘转动移动能够实现这种向上的转动。 Since the floor is connected with a tight initial position edge connector, the contact with each other through the upper edge and the connecting edge can be rotatably moved upwardly rotated to achieve this. 不仅当更换地板或移动地面板时,向上转动的可能性非常重要。 When replacing or only movable floor panel, the possibility is very important to rotate upward. 许多地板是试验铺设的或不正确地邻接门、在角落等处被铺设的。 Many trials floor is laid adjacent door or incorrectly, etc. are laid in the corner. 在铺设期间,如果在锁定系统没有被损害前提下,地板不能被轻易地拆卸,将是严重的缺点。 During the laying of, if not prejudice the locking system, the floor can not be easily disassembled, it would be a serious drawback. 可以向内倾斜的地板也可以再次向上倾斜,在利用向下倾斜连接时,条总是出现稍微向下弯曲情况,从而锁定元件向下向后弯曲并被打开。 The floor may be inclined inwardly inclined again may be, when the use of downwardly inclined connection bar always occur slight downward bowing, so that the locking element is bent rearwardly and downwardly open. 如果连接系统没有用适合的角度和半径形成,在铺设之后,地板可以用此种方式被锁定,也就是不能被拆卸(takingup)。 If the system does not connect with a suitable angle and radius are formed, after laying, the floor can be locked by this way, i.e. can not be disassembled (takingup). 当长边连接已经通过向上转动被开启后,短边总是可以沿连接边缘被拉出,但是如果短边可以通过向上转动而被开启,则效果更好。 When the connection has been pulled out of the longitudinal direction after being turned by the rotation, along the short side can always be connected to the edge, but if the short side can be opened by turning up, the better. 当地板是长的例如2.4米时,使拉出短边更困难,则优点更明显。 Local plate is 2.4 m long, for example, make more difficult the short side is pulled out, the more obvious advantages. 应该非常安全地实现向上转动,地板不会彼此卡塞和收聚,从而导致锁定系统被损害的风险。 Should achieve a very safe turning up, the floor will not jam and pinching each other, leading to the risk of damage to the locking system.

卡合应该通过水平卡合能够锁定地板的短边。 Engagement should be able to lock together the short sides of the floor level by card. 这要求连接系统的一部分是弹性和可弯曲的。 This system requires connection part is resilient and bendable. 即使与卡合相比,长边向内转动更容易更快速,由于一些诸如围绕门的铺设操作要求地板水平地连接,如果长边也可以被卡合,更具有优点。 Even compared with the engagement, the longitudinal rotation inward easier and faster, since some, such as around the door laying floor level connected to the operating requirements, if also the long side can be engaged, more advantages. 在可卡合连接时,如果连接部分的几何形状不适当,存在边缘升起的风险。 When the engagement can be connected, if the geometry of the connecting portion is inappropriate, there is a risk of edge rising.

长边和短边的材料成本如果地板的规格是1.2*0.2米,每平方米地面板的长边接头是短边接头的六倍。 Material costs of the long and short sides of the floor if the size is 1.2 * 0.2 m, each square meter long side joint of the short side panel linker six times. 与长边相比,大量材料消耗和昂贵的连接材料在短边是不重要的。 Compared with the long side, and a large amount of expensive material consumption in the short-side connecting material it is not critical.

水平强度为了获得高强度,锁定元件一般必须具有大啮合角,从而锁定元件不脱离(snapout)。 In order to obtain high strength levels of intensity, the locking element must generally have a large angle of engagement, so that the locking element without departing from the (snapout). 锁定元件必须高和宽,从而当承受地板在冬季由于低湿度而收缩所引起的高拉伸载荷时,锁定元件不断裂。 The locking element must be high and wide so that when subjected to high tensile load floor due to low humidity in winter due to shrinkage, without breaking the locking element. 这也适用于另一地板中最靠近锁定槽的材料。 This also applies to the material closest to the locking groove of another floor. 短边连接应该比长边连接具有更大的强度,由于在冬季收缩期间,拉伸载荷在短边的分布长度比在长边的分布长度更短。 Longer than the short side edge connector connection should have greater strength, since during the winter shrinkage, tensile load distribution of the short side length is shorter than the length of the long side of the distribution.

垂直强度当承受垂直负荷时,应该能够保持地板平面。 Vertical strength when subjected to vertical loads, should be able to keep the floor plane. 此外,由于承受压力并彼此相对运动的表面,例如上连接边缘可能导致发出吱吱响声,应该避免在连接处的运动。 Further, since the pressure receiving surface and relative to each other, for example, a connection may result in a creaking noise edge, it should be avoided at the connection of the motion.

移动性能够锁定所有四侧,新要铺设的地板必须能够在锁定位置沿已经被铺设的地板移动。 Mobility can lock all four sides, to the laying of a new floor must be able to move locations along the floor has been laid in the lock. 使用合理数量的力,应该能够实现这种情况,例如使用砌块和锤子,在连接边缘没有被损害同时连接系统无需被形成的具有水平和垂直可视间隙前提下,可以将地板结合在一起。 Using a reasonable amount of force, we should be able to achieve this, for example, block and hammer, while the attachment system is not compromised under the premise of having horizontal and vertical viewing gaps need not be formed, may be connected together at floor edge. 因为长连接导致更大的摩擦,长边上的移动性比短边上的移动性更重要。 Because the length of the connection results in a greater movement of friction is more important than the long side of the short side of the mobile.

生产性合理地使用具有良好精度和能力的大转动切削工具,应该能够生产连接系统。 Production of rationally using large rotatable cutting tool with good accuracy and capacity, the system should be able to produce the connection.

测量良好功能、生产公差和质量都要求连接外形轮廓可以被连续地测量和检查。 Measurement good function, production tolerance and quality require that the contour of the connection can be continuously measured and checked. 机械连接系统中的关键部分应该采用便于生产和测量的方式设计,应该能够在几十微米的公差范围内生产它们,应该能够高精度地测量它们,例如用所谓的轮廊投影仪。 The key part of the mechanical connection system should be used to facilitate the production of the design and measured manner, should be capable of producing them within a tolerance of tens of microns, they should be able to accurately measure, for example, a so-called contour with the projector. 如果使用线切割机加工生产连接系统,除了一定的生产公差之外,连接系统在整个边缘部分具有相同的外形。 If Cutting processing system is connected, in addition to certain production tolerances, have the same profile connection system in the entire edge portion. 通过用锯锯地板而锯下一些样品,利用轮廊投影仪或测量显微镜测量它们,可以高精度地测量连接系统。 By sawing with a sawing a floor and some of the samples, using a contour measuring microscope or projector measurement thereof, the connection system can be accurately measured. 然而合理生产要求连接系统也可以在不采用破坏方法的前提下被快速和轻易地测量,例如使用计量器(gauge)。 However, the reasonable requirements of the production system can also be connected quickly and easily measured without using a blasting method, for example using meter (gauge). 如果连接系统内关键元件数量尽可能地少,使用计量器测量是非常方便地。 If the number of the connection system key elements as small as possible, using a metering device is very easy to measure.

长边和短边的最佳化为了以最低成本最佳地制造地板,如上所述,鉴于它们的不同特性,长边和短边应该被优选。 Long side and a short side in order to optimize the manufacturing floor best at the lowest cost, as described above, in view of their different properties, the long and short side should be preferred. 例如长边应该优选向下转动、向上转动、定位和移动,短边优选卡合和高强度。 For example, the long side should preferably rotated downward, upward rotation, positioning and movement, and the short side is preferably high engagement strength. 地板的最佳设计是在长边和短边上应该具有不同的连接系统。 Floor is optimally designed in the long and short sides should have a different connection systems.

连接边缘横向移动的可能性随着相对湿度的变化,木基地板和通常包括木纤维的地板膨胀和收缩。 Possibility of lateral movement of the connecting edge with changes in relative humidity, wood flooring generally includes a base plate and the expansion and contraction of the wood fibers. 膨胀和收缩通常从上方开始,表面层可以比芯部也就是形成连接系统的部分移动的程度更大。 Expansion and contraction usually start from above, the surface layer may be formed than the core portion is greater part of the mobile system connections. 为了阻止上连接边缘部分由于高度膨胀而升高或被压碎,或在干燥时出现间隙,连接系统应该被如此构造,从而允许运动,以便对膨胀和收缩进行补偿。 To prevent the connecting edge portion since the height of the expansion is raised or crushed, or a gap occurs upon drying, it should be connected to the system thus configured, so as to allow movement in order to compensate for expansion and contraction.

发明本发明基于第一理解,通过使用适当的生产方法,基本上利用机加工,使用直径显著超过板厚度的工具,能够用木材、木基材料板(wood-basedboards)和塑料材料形成高精度合理的形状,这种类型机加工能够在距连接平面一定距离的舌榫槽内进行。 The present invention is based on a first understanding the invention, by using suitable production methods, essentially by the machining, the plate having a diameter significantly exceeds the thickness of the tool can be reasonably accurately formed of wood, wood-base material sheet (wood-basedboards) and plastic materials shape, this type of machining can be performed in the plane of the tongue groove connection from a certain distance. 从而连接系统的形状应该适于合理生产,能够以很小的公差进行。 Whereby the shape of the connection system should be adapted to rational production, it can be performed with little tolerance. 然而,不能以牺牲锁定系统和地板的其它重要特性为代价来产生这种适应性。 However, not at the expense of other important characteristics of the locking system and the floor at the expense of generating such adaptability.

本发明也基于第二理解,基于这种必须被最佳功能的机械连接系统满足的要求。 The present invention is also based on a second understanding, which must be satisfied based on mechanical connection of the best features of the system requirements. 这种理解能够以未知的方式实现,例如通过将a)这样设计连接系统,在系统的不同元件之间具有特殊的角度、半径、间隙、自由表面和比率,b)优选利用芯部的材料特性,例如压缩、延长、弯曲、抗拉强度和压缩强度进行组合。 This understanding can be realized in known manner, for example by a) designed connection system between the different elements of the system has a special angle, radius, clearance, and the ratio of the free surface, b) preferably using a core material characteristics , such as compression, elongation, bending, tensile strength and compressive strength are combined.

本发明还基于第三理解,在保证或改善功能和强度的前提下,通过结合制造技术、连接设计、材料选择和优选长边、短边,能够以低成本提供连接系统。 The present invention is further based on a third understanding, on the premise of ensure or improve the function and strength by combining manufacturing technique, joint design, choice of materials, and preferably the long side, short side, the connection system can be provided at low cost.

本发明基于第四理解,连接系统、制造技术和测量技术必须被发展和调整,从而要求很小公差的关键元件在更大程度上尽可能地少,并被设计的能够在连续生产中测量和检查。 The key element of the present invention based on a fourth understanding that the attachment systems, manufacturing techniques and measurement techniques must be developed and adjusted so small tolerance requirements to a greater extent as small as possible, and is designed in a continuous production can be measured and an examination.

在这个实施例中,在舌榫槽和舌榫上分别具有单独的啮合或支承表面43、64,在锁定状态下,它们彼此啮合,与下唇缘和舌榫上的下支承表面50、71相互配合,提供在垂直于表面平面HP的第一垂直方向D1上的锁定。 In this embodiment, in the tongue groove and tongue each have a separate bearing surfaces 43, 64 engage or, in the locked state, engaged with each other, with the lower surface of the upper bearing and the lower lip of the tongue 50,71 cooperate with each other to provide a locking in a first vertical direction D1 perpendicular to the surface plane HP is. 在将在下文所述的其它实施例中,锁定表面45、65被使用,其既被用作在平行于表面平面HP的第二水平方向D2上将两个地板锁定在一起的锁定表面,又被用于抵制在垂直于表面平面HP的第一垂直方向D1上的运动的支承表面。 In other embodiments will be described below, the locking surfaces 45, 65 are used, which are used as both D2 locked on two floor parallel to the surface plane HP in the horizontal direction with a second locking surface, and It is used to resist movement of the support surface in a first vertical direction D1 perpendicular to the surface plane HP is. 在图11a、2b所示实施例中,锁定表面45、65和啮合表面43、64作为该系统内的上支承表面共同合作。 In FIG. 11a, 2b embodiment illustrated embodiment, the locking surfaces 45, 65 and engagement surfaces 43, 64 cooperate as a support surface within the system.

从图中明显看到,舌榫38延伸到连接平面VP之外并在其自由外端69或末端具有向上指向部分8。 Apparent from the drawing, the tongue 38 extends beyond a plane VP and its outer free end or tip 69 having upwardly directed portion 8. 舌榫38也具有锁定表面65,当两个地板被机械相连时,锁定表面65与邻接地板上舌榫槽36内的内锁定表面45相互配合,从而它们的前侧面位于同一表面平面HP内并在与表面平面HP垂直的连接平面VP内相遇。 The tongue 38 also has a locking surface 65, when the two are mechanically connected to the floor, with the inner locking surface 65 in the tongue 36 abuts on the floor surface of the locking groove 45 cooperate with each other, so that their front sides lie in the same surface plane HP and VP HP meet in a plane perpendicular to the surface plane connection.

如图11b所示,舌榫38具有在锁定表面51和连接平面VP之间的表面部分52。 Shown in Figure 11b, the tongue 38 has a surface 51 between the locking surface and the connecting portion 52 of the plane VP. 当两个地板连接时,表面部分52与上唇缘8的表面部分45啮合,为了通过向内转动或卡合而将舌榫插入底切槽内,如图11a、11b所示,在锁定表面65和表面部分57之间,舌榫可以具有斜面66。 When connecting the floor two, the upper lip surface 52 and the surface portion 8 of the engaging portion 45, in order by rotating inwardly or engages the tongue is inserted into the undercut slots, as shown in FIG 11a, 11b, in the locking surface 65 between the surface and the portion 57, ramp 66 may have a tongue. 此外斜面68可以被设置在舌榫自由外端69和表面部分57之间。 Further ramp 68 may be disposed between the tongue portion 57 on the outer surface 69 and a free end. 通过具有一个向表面平面倾斜的角度,且该角度比锁定表面43、51的倾角A小,斜面66可以被用作导向部分。 By having a tilt angle to the surface plane, and the angle of inclination than the locking surface 43, 51 A small chamfer 66 may be used as a guide portion.

在该实施例中,舌榫的支承表面71基本上平行于表面平面HP。 In this embodiment, the bearing surface of the tongue 71 is substantially parallel to the surface plane HP. 在该支承表面和舌榫的自由外端69之间,舌榫具有一斜面70。 An outer surface of the support and the free end of the tongue is between 69, tongue 70 having an inclined surface.

根据本发明,下唇缘40具有用于与舌榫36上的相应支承表面71相互配合的支承表面50。 According to the present invention, the lower lip 40 has a bearing surface with a corresponding bearing surface 36 on the tongue 71 cooperating 50. 在该实施例中,该支承表面距底切槽的内部部分47有一定距离。 In this embodiment, the support surface from the bottom portion 47 of the slot inside a certain distance. 当两个地板彼此连接在一起时,在支承表面50、71之间以及上唇缘39啮合或支承表面43和舌榫上相应的啮合或支承表面64之间都存在啮合。 When the two joined floor with each other, the bearing surfaces 50,71 between the upper lip or edge 39 engages the bearing surface 43 and the tongue 64 are present between the engagement and the corresponding engaging or supporting surface. 用此方式,获得在垂直于表面平面HP的第一垂直方向D1上的锁定。 In this manner, a locking is obtained in a first vertical direction D1 perpendicular to the surface plane HP is.

最好,从与表面平面HP平行的方向看去,至少底切槽的内部部分47的主要部分比舌榫自由外端69或末端更远离连接平面VP。 Preferably, as viewed from a direction parallel to the surface plane HP, the internal undercut groove at least the main portion 47 than the outer free end of the tongue 69, or further away from the connection end plane VP. 利用这种设计,在很大程度上简化了制造,便于一个地板相对于另一个地板沿连接平面移动。 With this design, manufacture is simplified to a large extent, relative to the other to facilitate a floor the floor along the connection plane.

本发明机械锁定系统的另一个重要特征是从交点C也就是连接平面VP和表面平面HP的交点看去,与芯部30相连的下唇缘40的所有部分位于平面LP2之外。 Another important feature of a mechanical locking system of the present invention is connected is the intersection of the plane and the surface plane HP VP viewed from the intersection point C, as the lower lip portion 30 all connected to the core portion 40 is located outside the plane LP2. 与和平面LP2平行的锁定平面LP1相比,平面LP2更远离所述交点C,平面LP1与舌榫38和底切槽36的相互配合锁定表面45、65相切。 Locking plane LP2 and LP1 parallel plane compared to the plane LP2 intersection point C further away from, the plane LP1 cooperating with the tongue and the undercut groove 38 locking surface 36 tangent 45, 65. 相对于表面平面HP,这些锁定表面倾斜程度最大。 Relative to the surface plane HP, the locking surface is inclined maximally. 由于这种设计,如下文所述,通过使用用于机加工地板边缘部分的大盘形转动切削工具,可以加工底切部分。 Because of this design, as described below, by using a tape-shaped edge portion of the rotation of the cutting tool machining the floor, it can be processed undercut portions.

另一个重要特性是下唇缘40是有弹性的,其比上唇缘39更短。 Another important feature is the lower lip 40 is resilient, which is shorter than the upper lip 39. 这确保使用大盘形转动切削工具生产底切部分,由于相对于表面平面HP,大盘形转动切削工具可以被设定的具有相对大的角度,从而锁定表面65可以被制造的具有更大的锁定角A。 This ensures that the rotation produced using tape-shaped undercut the cutting tool, since the HP relative to the surface plane, tape-shaped having a relatively large angle rotation of the cutting tool can be set, so that the locking surface 65 may be manufactured has a larger locking angle A. 大的锁定角明显减少了引起拉伸载荷上升的向下成分。 Large locking angle significantly reduces the downward component causes a tensile load increase. 这意味着虽然下唇缘是弹性的,连接系统将具有高强度,从而具有有限的对抗向下成分的能力,从而在低卡合阻力下,获得高的锁定力。 This means that although the lower lip is resilient, having a high strength connection system, which has limited ability against downward component, thereby engaging at a low resistance, a high locking force is obtained. 高卡合阻力导致卡合困难,增加了损害地板边缘的风险。 Engaging high resistance lead to difficulty engaging, increasing the risk of damage to the edges of the floor. 发明人已经发现,通过使下唇缘具有在所优选连接系统内可以工作的适当厚度和长度,在地板内最常用材料可以被制造的具有充分弹性,并提供充分的锁定力。 The inventors have found that by having a suitable thickness and a lower lip length may work within the system is preferably connected, most commonly in the floor material may be manufactured with a sufficient locking force sufficient elasticity, and provided.

图12a~12c显示了通过弯曲下唇缘40而使两个地板卡合。 FIG. 12a ~ 12c shows the two boards bonded by the lower lip 40 is bent. 如图12b所示,在下唇缘具有最小程度的弯曲情况下,就可以实现卡合,同时地板的表面平面基本上在相同高度,这降低了破裂的风险。 Bending the case shown in Figure 12b, the lower lip has a minimum degree of engagement can be achieved, while the surface plane of the floor substantially at the same height, which reduces the risk of rupture.

图13a~13c显示符合图12a~12c的锁定系统在提起(taking-up)和铺设时也可以被向上转动(upwardangling)和向下转动。 FIG. 13a ~ 13c show locking system in lifting (taking-up) and the laying may also be rotated upward (upwardangling) turned downward and conform 12a ~ 12c of FIG. 上、下唇缘39和40以及舌榫38被形成的通过使一个地板相对于另一个地板围绕靠近连接平面VP和表面平面HP之间交点C的转动中心向上转动确保两个被机械连接的地板被拆卸分开,从而该地板的舌榫从另一个地板的底切槽中被转动出。 , The lower lip 39 and the tongue 40 and 38 is formed by a floor of the floor relative to the other about a rotational center close to the intersection C between the connecting plane VP and the surface plane HP is rotated upward to be connected mechanically to ensure that two floor disassembled separately, so that the floor of the tongue is rotated out of the undercut groove of the other floor.

符合本发明的卡合连接既可以被用在地板的长边又可以被用在短边上。 Card of the present invention meet both fit connection can be used in the long sides of the floor and can be used on the short sides.

然而图14和15显示本发明的一个变型,最重要的是其适用于沿由诸如硬木或硬纤维板等相对较硬材料制成的地板的短边卡合。 However, FIGS. 14 and 15 show a variant of the invention, the most important of which is suitable, such as along the floor made of hardwood or other relatively stiff material hardboard short edge card engagement.

在该实施例中,舌榫槽的深度超过接收舌榫所要求的深度。 In this embodiment, the depth of the tongue groove than is required for receiving the tongue depth. 因此使下唇缘40具有更高的弯曲性。 Thus the lower lip 40 has a higher bendability. 此外,锁定系统具有长舌榫,长舌榫带有形成厚锁定部件的向上指向部分。 Moreover, the locking system has a long tongue tongue, long tongue with a tongue forming a thick locking member upwardly directed portion. 锁定表面45、65也具有很大的倾斜角。 Locking surface 45 and 65 also have a large inclination angle. 虚线表示卡合动作。 Dashed line represents the engagement operation.

通过使一个地板向上转动并稍微向下弯曲另一个地板的下唇缘40,符合图14和15的设计允许两个地板被拆卸分开。 Floor by a downwardly bent pivoted upwardly and slightly lower lip 40 of the floor to another, consistent with the design of FIGS. 15 and 14 to be disassembled to allow two separate floor. 然而在本发明其它优选实施例中,在拆卸地板时,无需向下弯曲下唇缘。 However, in other preferred embodiments of the present invention, the floor during disassembly, without bending down the lower lip.

在锁定位置,能够沿连接纵向移动地板。 In the locked position, the floor can be moved longitudinally along the connection. 因此例如通过向上转动而拆卸长边之后,沿连接纵向拉出而拆卸短边。 Thus, for example, after disassembled by rotating the longitudinal direction, the longitudinal direction is connected disassembled pulled the short side.

为了便于制造、向内倾斜、向上倾斜、卡合以及在锁定位置移动性并降低破裂的风险,所有不用于与上连接边缘、垂直和水平连接边缘形成紧密连接的表面应该被形成的在锁定位置彼此不接触,最好在锁定和拆卸期间也不接触。 For ease of manufacture, inwardly inclined, upwardly inclined, and engages in the locking position in the locking position and reduce the risk of rupture, not all connected to the upper edge of the connecting vertical and horizontal edge surface forming a tight connection should be formed not contact each other, preferably in the locking and does not contact during disassembly. 从而在制造时允许这些连接部分不要求高精度公差,降低沿连接边缘横向移动时的摩擦。 Thereby allowing the manufacture of these connecting portions do not require close tolerances, friction reducing lateral movement along the connection edges. 在锁定位置彼此不接触的连接系统的表面或部分是由附图标记46-67、48-69、50-70和52-72所表示的部分。 The connection system in the locking position do not contact each other or the surface portion is a portion 46-67,48-69,50-70 and 52-72 indicated by the reference numeral.

符合优选实施例连接系统可以由几种材料组合制成。 Example accordance with a preferred embodiment may be made of a coupling system of several combinations of materials. 上唇缘39可以包括刚性和硬上表面32以及作为芯部30一部分的较软下部。 It may include a rigid upper lip 39 and the upper surface 32 and a softer hard as a lower portion of the core 30. 下唇缘40可以包括同样较软的上部30以及由另一种木材制成下软部34。 Lower lip 40 may comprise the same softer upper part 30 and a further timber formed by the lower portion 34 of soft. 三种木材的纤维方向可以不同。 Three Wood fiber direction may be different. 从而可以提供一种利用这些材料性能的连接系统。 Performance of these materials which can provide a connection system utilizing. 符合本发明的锁定元件被设置的靠近上硬和刚性部分,该部分的弹性和可压缩性是有限的,同时卡合功能由较软的下和弹性部分实现。 Consistent with the present invention is disposed adjacent to the locking member and the rigid hard portion, and the elastic compressibility of the part is limited, while the engagement of the functions implemented by a softer and lower elastic portion. 应该指出的是,连接系统可以由同一种材料制成。 It should be noted that the connection system can be made of the same material.

图16a~16c说明符合本发明地板的一个示例。 FIG. 16a ~ 16c illustrate an example of a floor in line with the present invention. 该实施例特别显示连接系统在长边和短边具有不同的设计。 This embodiment is particularly shows the connection of systems having different designs of the long and short sides. 在短边,通过具有大的锁定角、深的舌榫槽和比下唇缘短的上唇缘,同时锁定表面具有较小高度,以便减少向下弯曲的要求,锁定系统优选为卡合。 The short side, by having a larger locking angle, deep tongue groove and upper lip shorter than lower lip edge, while the locking surface has a small height, in order to reduce the requirements bent downward, the engagement preferably locking systems. 在长边,通过转动,该连接系统被调整,用于连接/卷起。 The long side, by rotating the connection system is adapted for connecting / rolling.

此外,连接系统可以包括不同的材料和材料组合30a、30b和30c。 Further, the connection system may comprise different materials and combinations of materials 30a, 30b and 30c. 能够在长边和短边选择不同的材料。 Different materials can be selected in the long and short sides. 例如短边上的槽36可以由例如比舌榫38更硬和更韧性的木材制成,舌榫38由硬和刚性并具有与长边芯部30不同特性的材料制成。 For example, the short side groove 36 may be formed, for example, than a tongue 38 made harder and more ductile timber, the tongue 38 of a hard and rigid material and has a long side portion of the core 30 is made different characteristics. 在具有舌榫槽36的短边上,例如能够选择一种木材30b,其比形成有舌榫38的其它短边上的木材30c更柔韧。 Having the short sides of the tongue groove 36, for example, select a timber 30b, which has a timber 38 of the other short side of the tongue more flexible than 30c is formed. 对于具有叠层芯部的拼花地板来说,更为方便,其上侧面和下侧面由不同木材制成,芯部由胶合块组成。 For parquet flooring with a laminated core, the more convenient, upper and lower sides which are made of different wood, a core glued blocks. 这种结构更可能改变材料的组合,以便优化功能、强度和生产成本。 This structure is more likely to change a combination of materials to optimize function, strength and production costs.

能够沿边长度改变材料。 Possible to change the length of the border material. 从而例如位于两个短边之间的块可以由不同木材或材料制成,从而能够根据它们的分布选择适当的特性,改善铺设、强度等。 Thus, for example, a block positioned between the two short sides can be made of wood or of different materials, it is possible to select the appropriate characteristics according to their distribution, improve laying, strength and the like. 通过长边和短边上纤维的不同朝向,可以实现不同特性,也可以在短边上使用塑料材料,例如在长边不同部分上。 By long sides and short sides toward different fibers, different characteristics can be achieved, the plastic material may be used in the short side, for example, in different portions of the long side. 如果地板或它的芯部的一部分由诸如具有几层的胶合板组成时,这些层可以被选择,从而在上边和短边上的上唇缘、舌榫和下唇缘可以使所有部分由不同材料组成,或具有不同的纤维朝向等。 If a part or the floor by its core, such as plywood with several layers of the composition, these layers may be selected so that the upper lip and the upper short side, the tongue and the lower lip can make all portions composed of different materials , or the like having different fiber orientation. 从而在强度、弯曲性、机械性等方面具有不同特性。 So as to have different characteristics in terms of strength, flexibility, mechanical properties and the like.

图17a~17c显示舌榫的下部如何相对于下唇缘40设计的基本原理,从而在包含刚性上唇缘39和弹性下唇缘40的连接系统内便于实现符合本发明的水平卡合,所述上唇缘39上具有底切部分或锁定槽8。 FIG. 17a ~ 17c shows how the lower portion of the tongue with respect to the basic principle of the lower lip 40 is designed so as to facilitate compliance level comprising the present invention engaging the rigid upper lip 39 and lower lip of the resilient coupling system 40, the upper lip portion 39 has an undercut or locking groove 8. 在该实施例中,由于更厚或由更硬和更刚性材料制成,与其它部分相比,上唇缘39更硬。 In this embodiment, since the thicker and made of a harder or more rigid material, as compared with other portions of the upper lip 39 is harder. 下唇缘40可以更薄、更软,在卡合连接时下唇缘40易于弯曲。 Lower lip 40 can be thinner, softer, when the snap connection of the lower lip 40 is bent easily. 由于尽可能地限制下唇缘40的最大弯曲,与其它方式相比,卡合更便于进行。 Due to limitations as far as possible the maximum bending of the lower lip 40, as compared with other types, for easier engagement. 图17a显示,下唇缘40的弯曲将增加到最大级别B1,也就是舌榫38插入舌榫槽36,圆形导向部分彼此接触。 Figure 17a shows that the bending of the lower lip 40 will increase to the maximum level B1, the tongue 38 is inserted into the tongue groove 36, the circular guide portion contact each other. 当进一步插入舌榫38时,下唇缘40将向回弯曲直到卡合终止以及形成锁定部件的向上指向部分8完全插入到其在底切部分35内的最终位置为止。 When the tongue 38 is further inserted, the lower lip 40 will be bent back until the termination of the engagement and the locking member is formed upwardly directed portion 8 is inserted fully into its final position until the cut in the inner bottom portion 35. 舌榫38的下和前部49应该被设计,从而该部分49不使下唇缘40向下弯曲,代替方案是利用下支承表面50使下唇缘40向下弯曲。 And under the tongue 49 of the front portion 38 should be designed so that the portion 49 without the lower lip 40 is bent downward, is supported by the following scheme in place of the surface 50 so that the lower lip 40 is bent downward. 舌榫的该部分49应该具有这样的形状,从而当下唇缘40沿舌榫38的下啮合表面50的外部被弯曲时,该部分49与处于最大弯曲级别的下唇缘40接触或不接触。 The part of the tongue 49 should have a shape such that when the lower lip 40 along the outer surface 38 engaging the tongue 50 when it is bent, the portion in contact with the lower lip 49 is bent at the maximum level 40 or not in contact. 如果舌榫38具有这样的形状,也就是在由虚线49b所示的覆盖下唇缘的位置,如图17b所示的弯曲B2可以明显更大,在进行卡合时可能导致更大的摩擦,出现连接点被损害的风险。 If the tongue 38 has such a shape, i.e. in the position shown by the broken line 49b covering the lower lip, the bending B2 shown in FIG. 17b can be significantly greater, it is engaged during may cause greater friction, the risk of damage appears to be the connection point. 图17c显示通过这样设计舌榫38和舌榫槽36可以限制最大弯曲,也就是舌榫下和外部49与下唇缘40之间具有空间S4。 Figure 17c show By designing the tongue 38 and the tongue groove 36 can limit the maximum bend, i.e. under the tongue and the outer edge 49 and a space S4 between the lower lip 40. 上唇缘被制造的具有更大的刚性,下唇缘具有更大的弹性,从而当地板受室内湿度影响而收缩和膨胀时,降低铺设后地板上侧面上的边缘向上升起的风险。 When the upper lip being made more rigid, it has a greater elasticity lower lip, so that the indoor humidity by the local board is contracted and expanded, after the laying of the floor to reduce the risk of side edge rises upwardly. 大刚性上唇缘与锁定表面的结合造成需要使用更大的沿连接点横向的拉开力。 Rigidity of the upper lip in combination with the locking surface results in the need to use a larger point of attachment along the transverse separating force. 下唇缘的弯曲有助于降低边缘升起的风险。 Lower lip curved edges help reduce the risk rises.

当锁定长边之后,通常在卡合连接短边时使用水平卡合。 After locking the longitudinal, generally horizontal edge when engaged in short-fit connection card. 当长边卡合时,也能够使本发明的连接系统与一个地板在稍微向上倾斜位置卡合。 When the long edge card engaged, the connection can be a floor system of the present invention in a slightly inclined position of engagement. 图18显示了这种向上倾斜卡合位置。 Figure 18 shows this engagement position upwardly inclined. 下唇缘40仅需弯曲很小程度,以便将锁定元件的导向部分66引导的与锁定槽内的导向部分44接触,从而通过向下转动,锁定部件可以被插入底切部分35内。 The lower lip 40 is bent only to a small extent, in order to guide the locking element contacting the guide portion 66 with the locking portion of the guide groove 44, so that by rotating downwards, the locking member may be inserted into the undercut inner portion 35.

图19和20也描述了在长边已经与另一个第一地板1连接之后两个地板2a和2b的短边卡合时可能出现的问题。 19 and 20 also describe a problem after long sides have a first floor connected to the other shorter edge card 2a and 2b are two floors timely possible. 当地板2a与地板2b通过卡合动作而连接时,最靠近第一地板1长边的内角部91和92位于同一个平面内。 When the floorboards 2a and 2b are connected to the floor through the engagement operation, closest to the first floor interior angle of the long side 1 91 and 92 lie in the same plane. 由于两个地板2a、2b的长边分别已与同一地板1相连,所以出现上述现象。 Since the length of two floor 2a, 2b, respectively, have been connected to the same side of the floor panel 1, so the above phenomenon. 如显示C3-C4断面的图20b所示,舌榫38不能插入舌榫槽39,以使下唇缘40向下弯曲。 The display shown in cross section in FIG. 20b C3-C4, the tongue 38 can not be inserted into the tongue groove 39, so that the lower lip 40 is bent downward. 如图20a中断面C3-C4所示,在另一长边上的外角部93、94上,通过使地板2b自动地受压并相对于锁定部件的高度向上倾斜,舌榫38可以插入舌榫槽36,并开始使下唇缘40向下弯曲。 20a in cross section in FIG C3-C4, on the outer corner portion 93, the other long side of the floor 2b by automatically pressed upwardly inclined with respect to the height of the locking member, the tongue 38 can be inserted into the tongue slot 36, and starts to lower lip 40 is bent downward.

发明人已经发现,当在舌榫的末端形成有向上指向部分并被插入配备有底切部分的舌榫槽内时,可能出现与内角部在同一平面内横向移动而卡合有关的问题。 The inventors have found that when the tongue is formed at the end portion directed upwardly and is inserted into the tongue groove with an undercut portion, problems may occur relating to lateral movement of inner corner portions in the same plane and engages. 这些问题导致卡合时出现大阻力,并在连接系统内出现破裂的风险。 These problems lead to big resistance is engaged, and the risk of rupture occurs in the connection system. 通过适当设计连接并选择确保材料在多个连接部分变形和弯曲的材料,可以解决上述问题。 And select the connection portion to ensure deformation and bending in a plurality of material as the connection, the above problems can be solved by appropriate design.

当卡合这种特殊设计的连接系统时,出现下列情况。 When this special design of the engagement connection system, the following occurs. 在横向移动时,舌榫和上唇缘的斜面42、68构成的外导向部分相互配合,迫使舌榫的向上指向部分或锁定部件位于上唇缘9外部的下方。 When the lateral movement, the outer guide portion and the upper lip of the tongue 42, 68 constituting the inclined surface cooperating forced upwardly directed part of the tongue or the locking member 9 is located below the outer upper lip. 如图20b中箭头所示,舌榫向下弯曲,上唇缘向上弯曲。 The arrow shown in FIG. 20b, the tongue is bent downward, the upper lip is bent upwardly. 图19中的角部92被正在弯曲的地板2b长边上的下唇缘40向上压,角部91被向上弯曲的地板2a长边上的上唇缘向下压。 The floor is curved corner portion 1992 in FIG. 2b long side of the lower lip 40 is pressed upwardly, the upper lip is bent upwardly floor corner portion 91 2a long side downwards. 连接系统应该具有这样的结构,从而这四种变形之和非常大,从而锁定部件可以沿上唇缘滑动并卡合到底切部分35内。 Such a connection system should have a structure such that the sum of these four deformation is very large, so that the locking member can slide along the upper lip and the engagement portion 35 cut in the end. 公知的是应该为了便于卡合,使舌榫槽36变宽。 It should be known in order to facilitate engaging the tongue groove 36 widens. 非公知的是,如果通常为刚性的舌榫被设计的在卡合时能够弯曲,也是非常优良的方案。 Not well-known that, if the generally rigid tongue designed capable of timely bent card, the program is also very good.

图21显示了这种示例。 Figure 21 shows such an example. 在垂直平面VP内侧,在舌榫的上和内部分上加工出槽或类似部位63。 In the inner vertical plane to VP, which the upper and inner part of the tongue groove machined portion 63 or the like. 舌榫的整个长度也就是从其内部到其外部的长度PB可以被延长,例如可以被制造的比地板厚度T的一半还大。 The entire length of the tongue that is can be extended from the inside to the outside length PB, e.g. less than half the floor thickness T may be made larger.

图22和23显示了在两个地板2a和2b的内角部91、92(图19)和外角部93、94(图19)卡合时,连接系统的部分如何弯曲。 22 and FIG. 23 shows two floor 2a and 2b of the inner corner portion 91, 92 (FIG. 19) and the outer corner portion 93, 94 (FIG. 19) is engaged, and how the system is connected to a curved portion. 为了简化制造,要求仅薄凸缘和舌榫弯曲。 To simplify manufacture, it requires only a thin flange and the tongue bend. 在实践中,当然材料厚度、弯曲性能、结构,所有承受压力的部分将被压缩并根据而弯曲不同的程度。 In practice, of course, the material thickness, bending property, structure, all of the pressure receiving portion will be compressed and bent according to different degrees.

图22a显示外角部93、94,图23a显示内角部91、92。 FIG outer corner portion 93, the display 22a, 23a in FIG. 91 and 92 show internal corner. 这两个图显示了当地板边缘彼此接触时的位置。 These two figures show the position of the local board edge contact with each other. 这样设计连接系统,从而即使在该位置,舌榫38的最外端也位于下唇缘40的外端之内。 Such design of the connector system, so that even in this position, the outermost end of the tongue 38 is also located within the outer end 40 of the lower lip. 当仍然彼此继续相向地推动地板时,如图22b和23b所示,舌榫38将在内角部91、92内向上压地板2b。 When the floor continues to push toward each other, as shown in FIG. 22b and 23b, the tongue 38 will press the floor 2b within the inner corner portion 91, 92 on. 舌榫38将向下弯曲,地板2b在外角部93、94将向上转动。 The tongue 38 is bent downward, the floor will turn upward 2b in the outer corner portion 93, 94. 图23c显示在内角部91、92部位上的舌榫38将向下弯曲。 Figure 23c show the tongue portions 91 and 92 on the inner corner portion 38 is bent downward. 如图22c所示,在外角部93、94,舌榫38向上弯曲,下唇缘40向下弯曲。 FIG. 22c, the outer corner portions 93, 94 in the tongue 38 is bent upwards, the lower lip 40 is bent downward. 如图22d和23d所示,随着仍然彼此继续相向地推动地板,这种弯曲连续,如图23d所示,下唇缘40也在内角部91、92向下弯曲。 , As the floor continues to push toward each other, such as shown in 22d and 23d continuously curved, as shown in FIG. 23d, the lower lip 40 are inner corner portion 91, 92 is bent downward. 图22d和23e显示了卡合状态。 FIGS. 22d and 23e shows the engagement state. 从而如果舌榫38也具有弹性,当地板沿两个其它边锁定之后,当地板在同一平面内卡合时,当舌榫和槽彼此接触时,如果舌榫38的外部位于下唇缘40的外部之内,显著地便于卡合。 So that if the tongue 38 also has elasticity, the floorboards along the other two sides, after locking, the local board is engaged in the same plane when the tongue and groove contact with each other, if the tongue 38 is positioned outside of the lower lip 40 the internal and external, significantly facilitates engagement.
