The invention relates to a sheet material which can be joined to a similar sheet material to form a panel surface. The invention is also related to a panel surface formed by interconnecting the floor panels of the present invention. The invention is further related to a method of assembling a plurality of sheets to form a panel.

Over the past decade, the market for laminated sheets used to make hard flooring has made great strides. There are currently several conventional ways of installing floor panels on the floor, that is, for example, the floor panels are placed on the floor below, which can be glued or nailed. The disadvantage of this technique is that the technique is complicated, and when it is desired to change it later, it is inevitable that the plate needs to be destroyed beforehand. According to another alternative installation method, the floor panels are mounted on the lower floor in a looser manner, and the ground plates are spliced to each other by means of a snap and groove connection, but most of them still need to use glue in the cassette or the groove. Connected to the connection. The floor that is constructed in this way, also known as floating parquet flooring, has the advantage of being easy to install and the surface of the finished floor is movable to withstand possible telescoping, and such floor panels The disadvantage of the surface is that if the floor panel is arranged on the lower floor in a loose manner, the floor material itself may be displaced when the floor is expanded or subsequently contracted, forming an unexpected gap, such as glued. The structure may split. In order to overcome this drawback, a single sheet material having a metal connecting element has been developed to facilitate the interconnection of the sheets; however, the connecting element The manufacturing cost of the parts is relatively expensive, and in addition, the installation of such products is quite time consuming. Therefore, it is necessary to improve the joining mechanism of the plate, especially for the floor plate, so that it has a durable and reliable connection structure at each edge, and has a relatively simple installation work, especially preferably without any connection means, such as glue Connect or metal connection components, etc.

It is an object of the present invention to provide an improved flooring which can be joined to other panels in an improved manner and which desirably excludes one or more of the above disadvantages.

Another object of the present invention is to provide an improved panel, particularly a flooring panel, which can be easily interconnected with other similar panels while ensuring a secure connection between the panels.

The present invention provides a sheet material, in particular a flooring sheet, which can be joined to other similar sheet materials to form a panel surface, comprising: a centrally disposed panel core having an upper side and a lower side, the core comprising: a first pair of opposite sides, comprising: a first side having a side latch extending substantially parallel to the upper side of the sheet, the front end portion of the side tab at least partially exhibiting a circular shape, the side of the side of the bottom of the cassette The end portion is a bearing portion, wherein the bottom rear end portion is closer to a horizontal plane of the upper side of the sheet than the lowest portion of the bottom front end portion; and an opposite second side has a groove for engaging the side of the other sheet At least a portion of the latch, the recess is formed by an upper edge and a lower edge, the lower edge having an upwardly projecting shoulder to support the abutment portion of the other plate side latch; the side card The fixing system is inserted into the groove of the other side of the sheet by a snapping action, and is pulled downward at an angle around the axis parallel to the first side, thereby making one side of the side clicker Bonded to a rim, and the bearing portion of the side latch is supported by the shoulder of the lower edge, so that the adjacent plate is simultaneously fixed by the horizontal and vertical directions on the first side and the second side; and a second pair is opposite The edge comprises: a third side having a single upper cassette, at least one upper side being disposed at a distance from the upper cassette, and a single upper slot being disposed between the upper cassette and the upper side, Wherein the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side of the upper side And a fourth side having a single lower jaw, at least one side of which is disposed at a distance from the lower cassette, and a single lower opening is disposed between the lower and lower sides, wherein the lower side The latch faces at least a portion of one of the lower sides toward a normal direction of the lower side of the core, and wherein the lower side has a substantially firm second securing member to be associated with the third side of the other panel The first fastening component cooperates, the third And the fourth side of the card is fixed, when the first side of one of the plates is pulled down to the second side of the other plate, and the fourth side of the plate to be engaged is to be engaged with the third side of the third plate The third side generates a scissoring action, whereby the card under the fourth side of the plate to be engaged is forced to be snapped into the third side of the third plate to be grooved, and above the third plate The slot is forced to be snapped under the plate to be engaged, and the third side and/or the fourth side are deformed to have the third side and the fourth side of the adjacent sheet simultaneously The horizontal and vertical snaps are fixed.

The sheet of the present invention has a first set of complementary joint shapes on the first pair of opposite sides and a second set of complementary joint shapes on a second pair of opposite sides, the first and second sides providing convenience The plate installation operation is performed by inserting the side of the plate into the second side of the plate to be installed obliquely, and then the plate can be pulled down at an angle (pivot manner) until both plates are Assume Placed on the same plane. Although the first side and the second side of the two plates are engaged and fixed in the horizontal and vertical directions by means of an angle downward, the third and fourth sides of the plate are specifically referred to When the engaging plate is engaged at an angle downward, the fourth side of the plate is forced to be engaged with the third side of the other plate to more stably fix the fixing effect. Since the third and fourth sides are always perpendicular to the first and second sides, a shearing action can be generated to cause the fourth side of a plate to be engaged with the third plate that has been mounted on the other plate. Three sides. The third side has a groove that is inclined upwardly, wherein the upper side of the upper side faces the normal direction of the upper side of the core, and the first side has an inwardly inclined lower jaw. Wherein the lower latch extends toward one of the lower sides toward the normal of the lower side of the core, so that the interconnection relationship between the third and fourth sides of the adjacent two plates can only pass through the third side and/or the fourth side. One of the sides (temporary) deformation, preferably elastic deformation, produces a stable, reliable and durable joint structure between the third and fourth sides. Therefore, the sheet of the present invention can be assembled by a simple method, and a stable and durable assembly structure can be brought about without additional joint components.

Between the first and second sides adjacent to the two plates, a horizontal locking engagement is established through the shoulders of the upward protrusions to avoid horizontal displacement of the bottom end portion of the side buckles. Therefore, the shoulder portion can engage and position the bottom front end portion of the side latch. Between the first side and the second side of the adjacent two sheets, a top surface of the side latch is engaged with a bottom surface of the upper edge of the fixing surface to establish a vertical locking engagement, wherein the The upper edge prevents the inserted side of the card from being displaced in the vertical direction. In the third and fourth sides, the horizontal direction between the two plates is locked and fixed, and the card is clamped to the bottom of the fourth side (the other plate) by the third side, and the two can be avoided. The plates are displaced from each other. In the third and fourth sides, the vertical direction of the two plates is locked and fixed by using the above-mentioned inner tilting groove, and further, by using the first and second engaging elements. Moreover, due to the special shape of the third and fourth sides, the locking and fixing of the rotation direction can also be established.

The (ground) sheet of the present invention is mainly directed to so-called laminate flooring, but is still applicable to other types of panels, including hard flooring, such as glued inlaid flooring, prefabricated box flooring, or other flooring similar to laminated flooring. material. The panels of the present invention can also be used to form panels for different applications, such as wall or ceiling panels.

As described above, the bottom surface of the front end portion of the cassette is at least partially circular, which facilitates the downward rotation of the sheet at an angle, wherein the central portion of the front end portion of the side cassette can be more or less as a pivot axis. effect. Since the side latch is inserted into the groove during the angle down rotation, the pivot shaft will be displaced during the angle down rotation. Generally, the bottom surface of the lower edge of the recess is configured to support the front end portion of the side latch, and the shape thereof is preferably complementary to the shape of the bottom front end portion of the side latch. In this manner, the number of gaps between the side latch and the bottom surface constituting the lower edge of the recess can be limited to a minimum number, and generally can avoid sway between the edges, thereby ensuring the stability of the connecting structure. Therefore, the bottom surface of the groove is preferably at least partially rounded. The circular shape of the mating surface may be a smooth rounded surface or (to some extent) a circular shape in the form of a hook, such as an element having a hooked surface. Alternatively, the bottom surface constituting the lower edge of the groove may take on other shapes, for example, a substantially flat shape, which may also facilitate the reduction of the frictional resistance between the two sheets during the lowering of the engagement, thereby assisting the installation process.

The upper and lower edges are attached to the core and preferably extend in a direction substantially flat with respect to the upper side of the core. Preferably, the lower edge is substantially longer than the upper edge and more preferably at least four times longer than the upper edge. A chamber is created between the upper and lower edges, the chamber also forming a portion of the recess. The chamber can be used as a locking and fixing portion of the groove, wherein one of the top surfaces of the engaging and fixing portion is used as The fixed joint is engaged and cooperates with the top surface of one of the front end portions of the other sheet side. Preferably, the engaging fixing surface is inclined, wherein a front end portion of the top surface of the side latch is inclined at least partially correspondingly. A slanted snap-fit attachment surface may facilitate engagement of the first and second sides of the panels.

In general, when the shoulder faces one side of the core with an inclined shape, the combined state facilitates forcing the two sheets to approach each other. Preferably, the bearing joints of the side latches have the same inclined shape, and the inclined structure is preferably inclined downward from the shoulder toward the core. By utilizing such a tilted structure, a driving surface can be created for driving (forcing) an inserted side click toward the center of the sheet, which is advantageous for stabilizing the joint between the first and second sides.

In a preferred embodiment, the side of the side latching portion is wider than the shoulder portion, and the width is perpendicular to the length of the side latch and the shoulder portion, and thus also the longitudinal direction of the first and second sides. The axes are perpendicular to each other. By using a bearing portion having a width wider than the shoulder portion, a gap is formed between the shoulder portion and an adjacent plate core, and since there is more space in the process of lowering the engagement, the gap helps one The process of turning the card under the angle.

The panels of the present invention may take on a square or rectangular shape. The first pair of opposite sides are disposed in parallel with each other, and the second pair of opposite sides are also the same, and are also substantially parallel to each other.

This upwardly corrected edge can present a plane and/or a circle. The upward correction edge facilitates the accurate positioning (alignment) of the fourth side of a sheet on the third side of the other sheet to assist in the joining of the third and fourth sides.

In a preferred embodiment, the side latches are oriented toward one of the sides of the upper side, and at least a portion forms an upwardly correcting edge for engaging the third side to a fourth side of an adjacent panel. This upwardly corrected edge can present a plane and/or a circle. The upward correction edge facilitates the accurate positioning (alignment) of the fourth side of a sheet on the third side of the other sheet to assist in the joining of the third and fourth sides.

Preferably, each of the upper and lower cassettes is substantially rigid, that is, the cassettes should not be easily deformed, and the cassettes should be rigid rather than elastic. Furthermore, the card is preferably substantially solid, that is, the card is substantially sturdy and solid, so that the upper surface does not have a slot that may affect the structure of the cassette. It will not further affect the connection structure between the floors. With a rigid and solid cassette, a robust and durable cassette can be made to create a reliable and durable connection between the panels without the need for separate additional components. The upper and lower latches are each coupled to the core by a bridge portion. Preferably, the bridge portions have a degree of resilience to allow for slight deformations that are often caused when the third and fourth sides are joined to each other.

In a preferred embodiment, the upper side of the flooring material is substantially seamlessly joined to the upper side of the other first sheet material, that is, the two sheets are joined by seamless joining of the upper surface.

In another embodiment, the first fastening component is disposed at a distance above the upper latch, which may have an advantageous effect, because the first fastening component is positioned in the first state. The upward correction side of the sheet is a low level surface, and the advantage is that the maximum deformation degree of the fourth side can be reduced during the connection and deformation in the subsequent step, and less deformation causes less material pressure. It is beneficial to prolong the life of the engaging component and thus affect the life of the flooring. In this embodiment, the second fastening component is complementary positioned at a distance from the upper side of the lower cassette. In different embodiments, the first fastening component is positioned at a certain distance from the lower side of the upper slot, which may also facilitate the card cooperation industry. The second clamping element that is complementary should be positioned such that the two fastening elements can cooperate in the third-stage fourth-side engagement state.

In another embodiment, the effective height of the downward correction edge is greater than the effective height of the upper slot, which often results in a downward correction of the floor panel in the pre-aligned state (intermediate state) is not engaged. In the case of another floor plate. The non-contact pre-alignment of selective positioning avoids or offsets the action of a floor to be corrected downwards and is forced to approach the upper surface of another floor plate, which may cause damage to the floor panel.

In one embodiment, the angle between one of the sides of the upper side facing the upper side and the upper side of the upper side is substantially equal to one of the sides of the lower side facing the lower side and the lower side of the lower side of the lower side The angle at which the normal line is placed, so that the two latching portions are tightly coupled, the reinforcing stability between the two plates can be enhanced. In an embodiment, an angle at which at least a portion of the upper side of the upper side facing the upper side is opposite to a normal line of the upper side of the core is variable, and is between 0 and 60 degrees, and more preferably The system is between 0 and 45 degrees, and the more accurate is between 0 and 10 degrees. In another embodiment, The angle at least a portion of the lower side of the lower side facing the lower side is variable from the normal line of the lower side of the core, and is between 0 and 60 degrees, more preferably between 0 and 45. Between degrees, the more accurate is between 0 and 10 degrees. The inclination of the clicker facing one side of the corresponding side is also determined according to the production method used to manufacture the flooring. In one embodiment, the slope of the downwardly-corrected side is smaller than at least the upper portion of the upper side, because an expansion chamber is formed between the two joints to allow for shaking and compensation, for example, the ground plate absorbs moisture. The degree of expansion produced.

In various embodiments, a portion of the upper side of the upper cassette extends toward the upper side of the upper side of the core, such that the thickness of the upper click decreases toward the side of the click away from the upper side. By substantially connecting the lower slot to the upper side of the upper latch, in the card engaging position of the two boards of the present invention, wherein the upper side of the lower latch extends toward a normal square line on the lower side of the core, a The fourth side, which is relatively strong and solid on the one hand, ensures sufficient elasticity on the other hand to complete the engagement action against the third side of the other sheet.

Preferably, at least a portion of the upper side of the upper latch is inclined downward toward a side of the upper latch away from the upper side, and wherein one of the lower slots is upwardly oriented in the same direction upward with the lower tab facing downward The direction of the side is inclined. In addition to the inclined upper side of the upper cassette being used as a calibrating edge to align the fourth side and the third side (the other sheet) with each other, the inclined surface may also allow a thicker bridge to connect the lower cassette to The core or the plate is used to ensure the reliability and durability of the plate. This tilting system can be flat or round, or even hook-shaped. It is contemplated that the upper side of the upper jaw may be circular and may be seamlessly coupled to the first fastening element, while the first fastening element also has a circular shape.

In various embodiments, at least a portion of the corrected edge of the fourth side has a shape that is substantially flatter than at least a portion of the upper side of the third side. By way of the method, an air gap between the corrected side of the fourth side and one side of the third side can be generated at the engaging position. This gap between the two snap-on components often provides a positive benefit when snap-on the ground sheet because the gap does not prevent the snap-in portion Temporary deformation, so that the engagement action of the engaging member can be facilitated. Furthermore, the resulting voids are advantageous for the expansion of the flooring material due to absorption. For example, if the moisture is absorbed, since the flooring is partially made of wood, this is a possible phenomenon.

In different embodiments, the third side is connected to the upper side of the core to form a stop surface for a portion of the lower latch away from one of the sides of the lower side, wherein at least the upper side of the sheet can be tightly formed Engagement, which is often a positive benefit for the user. The third side is connected to a portion of the upper side of the core, preferably in a substantially vertical shape. The lower latch is away from a portion of one of the sides of the lower side, preferably also in a substantially vertical shape. The two engaging members can have a positive effect by utilizing the substantially vertical blocking surfaces, so that the engaging members can be engaged with each other in a loose and stable manner when the engaging members are in the engaged position.

The upper slot can be joined in a sandwiched manner to the lower slotted engagement of one of the adjacent panels to provide a positive benefit. The benefit of the lower slot joining or at least partially engaging the upper slot is that the lower slot is closed by the upper slot in a tight fit, which enhances the stability of the snap fit. The same method is also used in different embodiments to join the lower slot in a sandwiching manner to a slot on an adjacent sheet.

In different embodiments, the upper side and the lower side extend substantially in a parallel direction, which enables the side surfaces and the fastening elements to be tightly engaged with each other at the engaging position, which can enhance the fastening caused by the fastening elements. effect.

In another embodiment, the first fastening component comprises at least one outer protrusion, the second fastening component comprises at least one groove, or both may be opposite, such that the outer protrusion is at least partially engaged adjacent to the engaging floor One of the grooves is formed in the groove to create a snap effect.
