BACKGROUND OF THE INVENTION

[0002] It is a problem in the art, when laying tiles on a surface, to equally level the tiles to be coplanar and space evenly the tiles. This is applicable to laying tiles on surfaces in general, including floors, walls, ceilings, and on other surfaces which can support tiles. The term tiles should be understood as including panels, sheets, boards, paving stones, and other materials capable of being laid out in a pattern.

[0003] US2014033641 A1 describes a two-part device system for installing tiles on flat surfaces, placed between two or more adjacent tiles, providing spacing, clamping and levelling for tiles, comprising:a knob-cam which is a rotatable top portion around a rotational axis, said knob-cam being adapted for levelling upper tile surfaces; said knob-cam having a body which has a central opening therethrough, said central opening being in a key shape formed by a central circular portion with a first slot and a second slot, wherein said first slot and said second slot extend in opposite directions from said central circular portion, and said knob-cam having a first cam outside of the body with a helically ascending teethed ramp about said central circular portion, said first cam having an upper surface radially extending from said central circular portion, said first cam having a lowermost edge adjacent said first slot; said knob-cam having a second cam outside of the body with a helically ascending teethed ramp about said central circular portion, said second cam having an upper surface radially extending from said central circular portion, said second cam having a lowermost edge adjacent said second slot; said knob-cam including a portion adapted for manual gripping by the user with a said knurled or ribbed gripping portion, and said knob-cam having a bottom seating clamping surface to level said tiles for coplanarity;a hook-base which is a fixed bottom portion having a base with spacing ribs for spacing adjacent tiles, and a hook having a tongue portion and a neck connecting said tongue portion to said base wherein said neck has a weakened breakable portion at the bottom which in use is disposed adjacent to said base; said hook portion having two engaging locking blades extending in opposite directions from said hook; and an extending from said base which is a bottom portion, said hook-base having a hook extending therefrom, said hook being adapted to pass through said opening in said knob-cam, and said hook having locking blades adapted to be engaged by respective ones of said cams, said hook-base being adapted to space and level the adjacent tiles in conjunction with the knob-cam from opposite sides of the tiles.

[0004] The present invention provides a two part device system for use in leveling and spacing tiles.

[0005] The device includes two parts, a rotatable portion and a fixed portion. The rotatable portion referred to hereinafter as a knob-cam includes two helical diametral opposed frontal action cams, a domed knob portion, a central opening, a knurled or ribbed portion and an annular surface portion at the bottom. The fixed portion referred to hereinafter as a hook-base includes a base with flat surfaces for seating the tiles and ribs for spacing and separating tiles, a neck portion extending through a slot in the knob-cam and double blades which will engage with the double cam. The installation does not require tools.

[0006] In use, the base portion is inserted from the side underneath the tiles and spaced by the ribs in between the tiles. After insertion of the base portion will be installed all surrounding tiles, and then the knob-cam will be inserted. The neck portion extends upwardly above the tiles, and is adapted to be broken away after the adhesive sets upon application of sufficient upward force or sideways force. The knob-cam is placed against the tiles such that the neck extends through the key opening. The knob-cam includes two diametral opposed frontal action cam surfaces that engage the blades when the knob-cam is rotated. The knob-cam is rotated until the tiles are temporarily secured between the knob-cam and the base. Adhesive is used to permanently secure the tiles on the surface. The device evenly holds the tiles in correct position during the curing process. When the adhesive is set, the neck and hook portions can be removed by breaking them away from the base portion. Clamping is provided from opposite directions, fastening the tiles in such a way that the upper surface of the tiles will be coplanar. Optionally the device may be used in conjunction with regular spacers, wider than the ribs and the device is providing just clamping force.

DETAILED DESCRIPTION OF THE INVENTION

[0009] A device 1000 according to the present invention is shown in FIG. 1, depicting a knob-cam portion 2000 and a hook-base portion 3000. The hook-base portion 3000 includes a hook 3100 and a base 3200. Three tiles 4100 are shown mounted against the base 3200 of the base portion 3000, and the tiles 4100 are shown as having side walls 4130. There is room for a fourth tile 4100 against the base portion 3200, which has been omitted for the sake of illustration. The device 1000 is provided for use in leveling and spacing tiles. The knob-cam portion 2000 is shown separated from the hook-base portion 3000, prior to assembly.

[0010] As shown in FIG. 1 and in FIGS. 4-6, the knob-cam portion 2000 has a domed knob shape 2300 and includes a pair of frontal cams 2100 (including a left cam 2110 and a right cam 2120, the left cam 2110 having an engaging edge 2111, a helical teethed and stepped cam profile 2112, an uppermost edge 2117, and an outer wall 2118. The right frontal cam 2120 has an engaging edge 2121, a helical teethed and stepped cam profile 2122, an uppermost edge 2127, a central opening 2200, a central key hole 2210, a central key slot 2220, an outer wall 2128, a knurling 2330 formed by alternating raised portions 2331 and recesses 2332, a surface 2310, a surface 2320, and an annular seating bottom surface 2350.

[0011] The hook-base portion 3000 is formed by a hook 3100 and a base 3200. The hook 3100 has a rounded key 3130 formed by a tongue 3133 which has a central hole 3131 with a chamfer 3132, a pair of engaging blades 3110 and 3120, and a neck 3140 which has two side surfaces 3141 and 3142. The neck 3140 is connected to the base 3200 by breakable portions 3150, consisting in the edge 3151 and the corners 3152 which are disposed at a bottom region of the neck 3140, situated under the tiles' upper surface. The base 3200 has a supporting flat wall 3210, a plurality of ribs 3220, each of the ribs 3220 respectively including a slanted portion 3222 and a top portion 3221, and a plurality of flat portions 3211. The plurality of flat portions 3211 respectively receive bottom corner portions of the tiles 4100 which are to be separated by the ribs 3220. The flat portions 3211 are provided between adjacent ones of the ribs 3220. FIG. 2a is a perspective view of the device of FIG. 1, showing an assembly step in which the knob-cam portion 2000 is brought toward the upper surfaces 4110 of the tiles 4100 in the direction shown by the dashed arrow D1.

[0012] FIG. 2b is a perspective view of the device of FIG. 1, showing the next assembly step in which the hook 3100 of the hook-base portion 3000 extends through the key opening 2200 of the knob-cam portion 2000 and the blades 3110 and 3120 extend above the cams 2110 and 2120 such that the engaging edges 2111 and 2121 of the cams are below the blades portions 3110 and 3120. The annular surface 2350 is touching the upper portion of tiles 4110. The knob-cam portion 2000 is about to be rotated in the direction shown by the dashed arrow R1, the shown mechanism is unlocked and does not provide residual force.

[0013] FIG. 2c is a perspective view of the device of FIG. 1, the shown assembly mechanism is locked. By rotating the knob-cam 2000, the frontal cams act as circular wedges and will provide the clamping residual force between the knob-cam 2000 and the tiles 4100. When the knob-cam is rotated beyond the first engaging position, the blades 3110 and 3120 will start climbing on the cams' teethed and stepped profiles 2112 and 2122, generating click sounds which can quantify the residual force necessary for proper clamping. It is important that the rotation is stopped after few clicks, to prevent breakage of the neck 3140 along the breakable portions 3151 and 3152. The clamping effect will self level the upper surfaces of the tiles 4110 until they all touch the annular surface 2350 which creates a datum plane for leveling. The clamping effect is similar to the force provided by the jaws from a vice. The self-leveling effect propagates to all adjacent tiles found under the knob-cam 2000. When the adhesive securing the tiles 4100 has been sufficiently set, the hook 3100 is adapted to be broken by fracture and can be removed, either by further rotation of the knob-cam portion 2000 or by striking of the hook 3100 in a sideways direction. The breaking edges 3152 and 3151 will be below the upper surface of tiles 4110 and will be covered later with grout and hidden. The hook portion 3100 can then be removed and the knob-cam portion 2000 can be reused.

[0014] FIG. 3a is a perspective section view of the device 1000 in the position shown in FIG. 2b wherein the hook 3100 of the hook-base portion 3000 is inserted through the key opening 2200 of the knob-cam portion 2000.

[0026] FIG. 8a is a perspective view of the knob-cam portion 2000 of FIG. 1 showing a knurled portion 2330. The remaining parts are as described in the foregoing.

[0027] FIG. 8b is a perspective view of another embodiment of the knob-cam portion 2000, having a plurality of separated rib portions 2340 for ease of gripping and rotating. The remaining parts are as described in the foregoing.

[0028] FIG. 9a is a side elevational view of a further embodiment of a knob-cam portion 2000 of FIG. 1, having an annular bottom surface 2350. Here, the cam 2120 is shown having respective engaging edge 2121 and uppermost edge 2127. By providing clamping force, the tiles will self level guided by the datum plane created by the bottom annular portion 2350 of the knob-cam. The knob-cam 2000 can be reused .The remaining parts are as numbered and described in the foregoing.

[0029] FIG. 9b is a top elevational view of the knob-cam portion 2000 of FIG. 9A, showing the cam 2110 and the cam 2120, together with the pairs of radial valleys 2115 and 2125. The pairs of radial valleys facilitate seating and locking of the blade portions 3110 and 3120 during operation.

[0030] FIG. 9c is an enlarged frontal section of a portion of the cam 2120, showing a close-up view of the teethed stepped radial valleys 2125. Each of the radial valleys 2125 has a generally scalloped shape, and includes the edges 2121 which prevents the blade portion 3110 and blade portion 3120 from unlocking itself; a valley portion 2124 which cooperates with the edge 2121 to prevent the blade portion 3110 and blade portion 3120 from unlocking itself; and a hill portion 2126 which allows a smooth transition to the next edge 2121 and provide residual force. Each of the radial valleys 2125 has an axial pitch h1, measured vertically between two consecutive edges 2121, and a depth h1a of the valley (which determines the key's sound pitch intensity during turning). Each of the radial valleys 2125 also has a total blade travel h1b from the bottom of a valley to the next edge 2121. Each of the radial valleys 2125 has a perimeter pitch p1 (e.g., a length p1), a distance p1a between and edge 2121 and the bottom of a valley, and a hill p1b which is a distance between the bottom of the valley to the next edge 2121, measured transversely. As seen in FIG. 9c, the radial valley 2125 has a concave portion 2124 where the locking ramp of the valley is located and a convex portion 2126 which leads smoothly to the next edge 2121. The cams have axial and frontal action, and the orientation of the edges 2121 from the teethed and stepped profile is in opposite direction from the tiles.

[0031] FIG. 9d is an enlarged section view of an assembly formed by a blade 3120 which looks like a V-Notch and the cam teethed and stepped profile 2122. The tip edge 3122 and two adjacent sidewalls 3121 seats and engages with the locking valley portions 2124 wherein the edge 2121 and the locking ramp 2124 prevent the tip blades 3122 from unlocking themselves. Upon further urging of the blade portion 3110 during rotation of the knob-cam portion 2000, the tip 3122 slides upwardly along the hill portion 2126 which forms a smooth transition to the next edge 2121 whereupon the tip 3122 can slide into the next radial valley portion 2125. In this preferred embodiment, this sharp and central V shape is very effective in engaging with the teethed stepped profile on cams. Because the teeth have a radial pattern, i.e. are radially disposed, the blades 3110, 3120 have to engage in a substantially exactly radial manner, and this determines that the sharp blades tips 3122 will be substantially exactly in the middle of the radial valleys 2125 and 2115.

[0032] FIG. 10 is a perspective view of a further embodiment of a knob-cam portion 2000 which can be used in the device of FIG. 1, wherein the cams 2110 and 2120 have smooth or textured surfaces instead of teethed and stepped surfaces.

[0033] FIG. 11 is a perspective view of a further embodiment of a knob-cam portion 2000 which can be used in the device of FIG. 1, wherein the cams 2110 and 2120 have smooth or textured surfaces instead of teethed and stepped surfaces as well as a plurality of ribs 2340 for facilitating manual gripping and turning.

[0034] In the foregoing description, the frontal cams have specified surfaces. It is contemplated as being within the scope of the present invention that the frontal surfaces of helical cams can have any of: teethed and stepped surfaces; textured surfaces; or smooth surfaces. This includes teethed stepped surfaces as described above.

[0035] FIG. 12a is a frontal sectional view showing a base portion 3200, shown sliding into engagement from the side under the tile 4100 in the direction indicated by an arrow D2. The tile 4100 is disposed on the adhesive 4200 which is covering the floor 4300.

[0036] FIG. 12b is an enlarged view of the chamfer 3212 portion. In this view the seating wall 3210 through the seating surface 3211 of the base 3200 is supporting a tile 4100. The leading edge of the wall 3100 has the downward oriented chamfer 3212, wherein the chamfer 3212 assists in penetrating the adhesive A along with an arrow labeled D2 showing a direction of insertion or movement. That is, the chamfer 3212 in this process will push down the adhesive 4200 so as to help rub and clean the lower seating surface 4120 of tile 4100 from the adhesive 4200 in the location adjacent to the base 3200. In this view, an arrow labeled D3 shows a direction in which the adhesive A is pushed down by the chamfer 3212, such that adhesive is cleaned from underneath the tile 4100, providing a clean supporting surface.

[0037] The invention being thus described, it will be evident that the same may be varied in many ways by a routineer in the applicable arts. Such variations are not to be regarded as a departure from the scope of the invention and all such modifications are intended to be included within the scope of the claims.

[0038] The invention has several preferred embodiments but they are not exclusive. The invention is susceptible of many embodiments, all of which are within the scope of the appended claims.

5. Le dispositif de la revendication 3, selon lequel la rotation de ladite came à molette (2000) se produit en quatre étapes principales : (a) La rotation initiale de ladite came à molette (2000) ne produit aucun cliquetis car les lames de verrouillage (3110, 3120) n'engagent pas encore la portion ascendante de ces cames (2110, 2120) et le dispositif ne fournit encore aucune force de serrage et aucun cliquetis pendant cette rotation initiale de ladite came à molette (2000) ; (b) Une rotation additionnelle de ladite came à molette (2000) produit des cliquetis, une fois que la surface inférieure annulaire (2350) de ladite came à molette (2000) touche la surface supérieure des carreaux et ces lames de verrouillage (3110, 3120) s'engagent avec ladite portion ascendante dentée des cames (2110, 2120), la rotation additionnelle de ladite came à molette (2000) commence à augmenter la force de serrage à mesure que ces lames de verrouillage (3110, 3120) dudit crochet (3100) s'engagent avec le profil ascendant des cames (2110, 2120) et ledit profil denté disposé radialement (2112, 2122) provoque des cliquetis, soit une indication audible en comptant où arrêter la rotation de ladite came à molette (2000) afin de ne pas dépasser la force de serrage maximum autorisée et de ne pas casser prématurément ladite base à crochet (3000) au niveau de la portion facilement cassable (3150), et chaque cliquetis consécutif procure un feedback audible lié exclusivement à l'augmentation de la force de serrage résiduelle, et en comptant les cliquetis, soit quatre, la force de serrage résiduelle atteint la force maximum autorisée et l'utilisateur sait exactement où arrêter la came à molette (2000), juste avant d'atteindre la force d'élongation maximum requise pour casser le crochet de la base (3000) au fond ; (c) Cessez la rotation de ladite came à molette (2000) une fois atteinte la force de serrage maximum autorisée, mesurée par le nombre de cliquetis, et lorsque la force de serrage atteint le maximum autorisé à la fin de la rotation de ladite came à molette (2000) et ladite came à molette (2000) est libérée et laissée verrouillée en position alors que les carreaux sont sécurisés en place avec les surfaces supérieures coplanaires et l'adhésif commence à sécher avec des carreaux espacés, serrés et nivelés ; (d) La poursuite de la rotation de ladite came à molette (2000) une fois l'adhésif sec et les carreaux sécurisés, va rompre intentionnellement la base à crochet (3000) sur la portion cassable (3150) de la portion inférieure dudit col (3140) et ladite clé (3130) se casse alors que la base restante (3200) et les nervures (3220) restent intégrées sous la surface supérieure des carreaux et entre les carreaux adjacents puis la portion supérieure (3100) de la base à crochet (3000) est extraite d'entre les carreaux après la casse, les espaces étant remplis de mastic ; et il existe une méthode alternative de rupture de la base à crochet (3000) inférieure après le séchage de l'adhésif en frappant latéralement l'assemblage serré de came à molette (2000) et de base à crochet (3000) sans rotation de ladite came à molette (2000).

6. Le dispositif de la revendication 3, selon lequel pour chacune de ces portions dentées ascendantes de forme hélicoïdale de came, ces portions convexes assurent des transitions régulières avec les portions concaves suivantes, verrouillant ces lames de verrouillage dans les portions concaves.

7. Le dispositif de la revendication 1, selon lequel ces première et seconde cames (2110, 2120) présentent un angle ascendant relativement moyen et les surfaces supérieures de chaque came (2110, 2120) sont texturées pour faciliter l'assise et le verrouillage par friction de ces lames de verrouillage (3110, 3120) procurant une hausse de la force de serrage incrémentielle afin de niveler les carreaux sur une surface coplanaire.

8. Le dispositif de la revendication 1, selon lequel ladite base à crochet (3000) est adaptée au soutien et au serrage des carreaux adjacents en conjonction avec ladite came à molette (2000) depuis les côtés opposés des carreaux et est aussi adaptée à l'espacement des carreaux adjacents grâce à ses nervures (3220) qui assurent des espaces entre les carreaux adjacents et ledit col (3140) de la portion inférieure de ladite base à crochet présente une portion facilement cassable (3150) et la portion inférieure reste piégée sous les carreaux.

9. Le dispositif de la revendication 1, selon lequel une portion supérieure (3130) de ladite base à crochet (3000) présente une forme de clé pour faciliter la prise et le maintien en position par l'utilisateur alors que ladite came à molette (2000) est tournée par l'utilisateur et ladite clé (3130) est adaptée à la traversée de ladite ouverture (2200) dans ladite came à molette (2000) et verrouille ladite came à molette (2000).

10. Le dispositif de la revendication 1, selon lequel ledit crochet (3100) de ladite base à crochet (3000) comporte un bloc substantiellement en forme de T et ces lames de verrouillage (3110, 3120) sont disposées sous les bras respectifs dudit bloc en forme de T.

11. Le dispositif de la revendication 1, selon lequel chacune de ces paires de lames de verrouillage (3110, 3120) de ladite base à crochet (3000) présente un profil de verrouillage qui s'étrécit jusqu'à un bord incliné qui peut s'engager et verrouiller les portions concaves radiales correspondantes ou les surfaces texturées de ces cames (2110, 2120) à la fin de la rotation de ladite came à molette (2000).

12. Le dispositif de la revendication 1, selon lequel ladite base à crochet (3000) présente une forme carrée au fond avec des coins en V pénétrant sous ces carreaux et les rebords inférieurs entourant ladite base à crochet (3000) sont substantiellement chanfreinés vers le bas et sont adaptés à une insertion facile sous les carreaux alors que les chanfreins facilitent le retrait de l'adhésif durant l'insertion depuis la surface inférieure de ces carreaux, éliminant l'adhésif de la surface inférieure desdits carreaux et fournissant une surface d'assise relativement propre entre la surface d'appui supérieure de ladite base et la surface d'assise inférieure de ces carreaux, offrant un meilleur nivellement de ces carreaux.

13. Le dispositif de la revendication 1, selon lequel ladite base à crochet (3000) est proposée dans un matériau de différentes couleurs, chacune représentant différentes épaisseurs d'espacement de nervures se trouvant entre les carreaux adjacents.

14. Le dispositif de la revendication 1, selon lequel ladite base à crochet (3000) présente des espaceurs nervurés saillants (3220) présentant un matériau continu sur toute ladite base à crochet (3000), sans espaces.
