Description

FIELD OF THE INVENTION The present invention relates to alignment adjustment devices, and more particularly to alignment adjustments to align the surfaces of tiles as they are laid.

In laying tiles, matching the surface height of the tiles is very important in providing a smooth surface and also in the aesthetic appearance of the laid tiles. Heretofore, there have been devices for aligning and leveling tiles, including a top plate with a plurality of spacer fins and a bottom plate to which the top and bottom plates are connected, extending through the top plate to create a special surface shape. a shaft having a top plate movable along the length of the shaft and positioned between adjacent tiles, the top and bottom plates holding the adjacent tiles at a desired height. A device has been proposed (for example, Patent Document 1). However, when such a shaft is used, the shaft is inevitably thick, and a joint width that allows the shaft to pass through is required.

On the other hand, it is composed of a clip and a wedge, and the clip includes a bottom plate surface, a fixing portion that fixes the upper part of the wedge, and a support portion that rises vertically from the bottom plate surface and is integrated with the fixing portion, A clip cutting portion is provided in the vicinity of the lower surface of the support portion, the wedge has a top plate surface at its lower portion, and a fixing slant portion is provided at its upper portion in contact with the fixing portion. There has been proposed an auxiliary tool for planar configuration of a tile surface, which can be inserted between a fixed part and is characterized by crimping and fixing the top plate surface to two adjacent tiles (see, for example, Patent Reference 2). This auxiliary jig can also handle tiles with narrow joints compared to the above-described apparatus that requires a thick shaft. However, the thickness of the struts is required and clip cuts must be provided. Furthermore, due to its clip shape, it can only be applied between the sides of adjacent tiles and is difficult to accommodate if the sides are not straight.

Also, in a surface alignment adjusting device used for laying tiles that can flexibly cope with various conditions (for example, Patent Document 3), the distance adjusting member is arranged on a predetermined surface so that the engaging moving body can engage with the distance adjusting member. Due to the shape, it is difficult to narrow the joints.

However, in laying tiles, there is a movement to secure a predetermined width in consideration of the effectiveness of the joints, but it is believed that narrowing the joint width is preferable in order to maximize the beauty of the tiles. there is In order to maximize the aesthetic appearance, it is very important that the tile surfaces match each other. Also, for the self-expression of the tiles, the sides are not necessarily straight. Also, it is more effective if the surfaces of three or more tiles can be matched at a joint intersection. In addition, it goes without saying that flexibility in the timing of insertion of such adjustment devices is highly desirable.

Accordingly, the present invention provides a surface alignment adjustment device that can handle even narrow joints. Additionally, the adjustment device may be capable of aligning the faces of more than two tiles. In addition, the adjustment device may have flexibility in the timing of insertion. It may also be possible to match faces of tiles with different shapes.

The inventors of the present invention have considered the above-mentioned problems, and have conducted intensive research on the functions of the shaft, the distance adjusting member, etc. in the conventional technology as described above. By arranging, it came to make the invention which can solve such a subject.

An adjustment device (hereinafter referred to as "this device"), which is one embodiment of the present invention, engages a portion at a predetermined distance from the bottom surface of the tile or the tile surface and moves in conjunction with the position of the surface. a distance adjusting member comprising an engaging member, a thin shaft extending from the engaging member, and a thick shaft connected to the thin shaft; an abutting member that can be sandwiched between the narrow shaft and the thick shaft and is freely movable in the direction of rotation of the thin shaft and the thick shaft; and an engaging movement that can press the abutting member toward the engaging member. and a member. The apparatus further comprises an opening near the center thereof through which an engaging member provided at the tip of the thin shaft can pass or engage depending on its orientation. A member can be provided.

Face-to-face adjustment devices such as those described above allow efficient installation of tiles even when the joints are very narrow and even when the joints are not necessarily straight.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited by these.

FIG. 1 shows a schematic view of a vertical cross-sectional view showing a state in which tiles are aligned with a surface alignment adjusting device or the like of one embodiment of the present invention. The face alignment adjusting device 10 includes, from the top in the drawing, a head 12, a thick shaft 14, a thin shaft 16, and an elongated rod-shaped distance adjusting member having an engaging member 18. As shown in FIG. Although these may be configured by combining individual parts, they are integrated as a whole. The thick shaft 14 has a predetermined surface profile 20 that can provide a force for pressing against the tiles as described below. An engaging moving member 22 such as a nut having an inner surface shape 24 that is screwed or engaged with the surface shape of the thick shaft 14 (in this embodiment, a male thread is threaded) is attached to the thick shaft 14 and It is pierced by a thin shaft 16 . It is preferable that the thick shaft 14 and the thin shaft 16 have substantially the same axial center (the axial centers match). The engagement moving member 22 has a concave portion 26 with a small outer diameter in the middle in the axial direction, and a flange portion 27 with a slightly larger outer diameter below it. A through-hole is provided substantially in the center of the engaging and moving member 22, and a female thread is formed in the inner surface shape 24 thereof. The surface shape 20 formed by the threading of the male thread of the thick shaft 14 and the inner surface shape 24 formed by the threading of the female thread are engaged with each other, and the engaging moving member 22 rotates around the thick shaft to engage. The moving member 22 can move up and down in the axial direction of the thick shaft 14 in the drawing. In the drawing, a donut-shaped or disk-shaped abutment member 30 having a through hole provided substantially in the center is disposed under the flange portion 27 . The contact member 30 has three claw portions 28 on its upper surface, and the claw portions 28 are engaged with the flange portion 27 with a clearance so that the contact member 30 is rotatable with respect to the flange portion 27 . The lower surface of the abutment member 30 abuts on the surfaces of the adjacent tiles 40a and 40b, and further presses the surfaces of the tiles 40a and 40b together. The lower surfaces of both tiles 40a and 40b are provided with a lower receiving member 32 engageable with the engaging member 18 and are engaged at a substantially central through hole 35a. The lower receiving member 32 is provided with a notch 34 communicating with the through hole 35a. In this manner, adjacent tiles 40a and 40b are sandwiched between the lower surface of the abutment member and the upper surface of lower receiving member 32. As shown in FIG. Although details will be described later, these tiles 40a and 40b are placed on mortar (which may contain an adhesive; the same shall apply hereinafter) 60 that is applied or arranged on the laying surface 50, and the weight of the tiles and the tile surface is reduced. The pressing force from the bottom can stabilize the mortar under the lower surface to crush it. Therefore, the tiles 40a and 40b are not always at the same height from the laying surface 50 due to differences in the amount of mortar, the placement location, the pressing force, and the like. Therefore, it is important to match the height of the surface (that is, match the surfaces of the tile surfaces) using the above-described surface matching adjusting device or the like.

2 to 4 show a perspective view, a front view, and a cross-sectional view along AA of a face-to-face adjustment device, etc., according to one embodiment of the present invention. A convex portion 12a is formed on the top of the head 12 in a radial direction, and the direction of this is interlocked with the direction of the engaging member 18. direction can be known.

FIG. 5 shows a schematic view of a vertical cross-sectional view showing a state in which tiles are mated with the mating adjustment device of one embodiment of the present invention. Here, except that the lower receiving member is not used, it is substantially the same as that of FIG. 1, so redundant description will be omitted. A thin shaft having a diameter D narrower than the joint width defined by the side edges of both adjacent tiles (if the thin shaft does not have a right cylindrical shape, the length corresponds to the diameter) is passed through the joint and engaged The top edge of member 18 extends beyond the bottom surfaces of both tiles 40a and 40b. Then, looking at the direction of the convex portion 12a (here, it coincides with the longitudinal direction of the engaging member 18), the head 12 is moved so that the longitudinal direction of the engaging member 18 is substantially perpendicular to the joint. The direction of the engaging member 18 is changed by rotating the thick shaft 14 and the thin shaft 16 in conjunction with each other. In this way, the longitudinal distance L becomes larger than the width of the joint, and the engaging member 18 is locked or engaged with the lower surfaces of both the tiles 40a and 40b, preventing it from slipping out of the joint. In this way, if the diameter of the thin shaft 16 or the length corresponding to the diameter (for example, when the cross section is an ellipse, the minor axis, the shorter length) is shortened, it is possible to cope with thinner joints. For example, if the joint is 3 mm, it is preferable to use a cylinder or a wire narrower than φ3. For a joint of 2 mm, a cylinder or wire rod thinner than φ2 is preferable. For a joint of 1 mm, a cylinder or wire rod thinner than φ1 is preferable. For example, a cylinder or wire having a diameter of φ0.8, φ0.7, φ0.6, φ0.5 or less is preferable.

The engaging member 18 has a length L in the longitudinal direction, a length D in the width direction perpendicular to the longitudinal direction, and a predetermined height in the height direction parallel to the thin axis. It may be shaped like a square bar. Alternatively, the engaging member 18 extending longitudinally around the portion connected to the thin shaft may be shaped like a fish hook with hooks on both sides of the connecting portion. In the illustrated embodiment, it is connected to the slender shaft 16 approximately in the middle of its longitudinal length L. As shown in FIG. It can be seen from FIG. 5 that it exhibits a T-shaped shape. However, it is not limited to the T-shape, and may be an L-shape (for example, when one side is short). When this engaging member 18 is rotated about the thin shaft 16 by 90 degrees, its width D corresponds to the diameter of the thin shaft 16 or the length corresponding to the diameter, as can be seen from the notch 34 in FIGS. Therefore, rotation about the thin shaft 16 can make it smaller than the joint width, while rotation about the thin shaft 16 can exceed the joint width and engage the lower surfaces of both adjacent tiles 40a and 40b. Such an engaging member 18 can be formed when forming the thin shaft 16 from a wire rod. For example, it is possible to make something like a nail head and press or tap it in one direction in the radial direction to make it as thick as the diameter of the slender shaft and to be as wide as or wider than the nail head. It is preferable that the wire constituting such a thin shaft is made of metal. In particular, iron-based metals are preferable because of the availability of materials. If it is made of stainless steel, rust can be effectively prevented. In addition, by performing appropriate heat treatment, it is possible to provide sufficient strength (especially tensile strength).

In conventional ones, the shaft or the like corresponding to such a thin shaft has a surface shape like a threaded male screw, and the undulations cause the thinnest (that is, weakest) part to have a diameter or diameter-equivalent length. must be much shorter (narrower) than the width of the joint, and there is a risk that it will not be able to withstand the clamping force when the tile is sandwiched. Since the thin shafts in the examples of the present invention have smooth surfaces without undulations, the thin shafts can be sufficiently thin while maintaining sufficient tensile strength. For example, it may be said that it is a shaft with a certain thickness. In addition, since conventional shafts and the like having a surface shape require dimensions of the surface shape that are proportional to the thickness of the shaft, etc., it is more difficult to form a surface shape for thinner shafts. . And, for features made with smaller dimensions, the distance of axial movement in engagement with the feature is reduced, as if in proportion to its size. Therefore, the operation for adjustment may become more complicated, and, for example, in the case of a screw or the like, the number of rotations may increase. More specifically, the JIS screw has an effective diameter of M1 of 0.838 mm, a pitch of 0.25 mm, an effective diameter of M2 of 1.74 mm, a pitch of 0.4 mm, and an effective diameter of is 2.208 mm with a pitch of 0.45 mm, M3 with an effective diameter of 2.675 mm with a pitch of 0.5 mm, and M4 with an effective diameter of 3.545 mm with a pitch of 0.45 mm. Since it is 7 mm, the smaller the diameter, the greater the number of rotations for the same movement. On the other hand, if the diameter is large, the joint width to be entered cannot be narrowed.

Since the slender shaft of the adjuster embodying the present invention has been removed from its ability to engage the engaging moving member, it can be made thinner without sacrificing various requirements. The length of the thin shaft 16 may be longer than the thickness of the tile to be mated, or the distance between the tile surface and the portion (for example, the engagement portion such as a concave portion or a convex portion) whose position is interlocked. Industrially, the upper end of the engaging member 18 (the side in which the thin shaft 16 extends) exceeds the thickness of such a tile or the distance between the tile surface and the positionally interlocking portion. Because of the clearance required for pivoting, the slender shaft 16 may have a length that exceeds the thickness of the tile, or the like. On the other hand, since the thick shaft 14 connected to the thin shaft 16 is not inserted into a joint, the thick shaft 14 is sufficiently satisfactory in terms of tensile strength as described above and in terms of axial movement distance with respect to rotation around the shaft. can be made For example, the outer diameter (maximum diameter including the surface shape) of the thick shaft 14 is φ5 or more, φ6 or more, φ7 or more, φ8 or more, φ9 or more, φ10 or more, φ11 or more, φ12 or more, φ13 or more, φ10 or more, and φ11. Any one of the above may be used. There is no particular upper limit, but for use as a hand tool, if it is too large, it becomes difficult to handle. When this is expressed by the ratio of the diameter of the thick shaft or the length corresponding to the diameter to the diameter of the thin shaft or the length corresponding to the diameter, it is about 1.5 times or more, about 2 times or more, about 3 times or more, about 4 times or more, about 5 times or more, about 6 times or more, about 7 times or more, about 8 times or more, about 9 times or more, about 10 times or more, about 11 times or more, about 12 times or more, about 13 times or more, about 14 times or more, about It may be 15 times or more. There is no particular upper limit, but in order to use it as a hand tool, if it is too large, it will be difficult to handle, so it can be said that 1000 times or less is practical. Also, the axial lengths of the thick shaft 14 and thin shaft 16 may be longer than the sum of the thickness of the tile and the thickness of the contact member. Further, it can be as long as possible to provide sufficient clearance to comfortably insert the adjustment device 10 into the tiles 40a and 40b. To facilitate the turning operation, a special pitch can be set if large longitudinal travel with less rotation is desired. For example, in a screw having an outer diameter of about 10 mm and a pitch of about 5 mm, it is possible to move about 5 mm in the direction of the screw axis by rotating an engaging moving body, which will be described later. Assuming that the thickness of the tiles to be clamped is about 6 mm, one rotation of the engaging moving body results in a movement equivalent to about 0.8 times the clamping distance (corresponding to the thickness of the object to be clamped when the tiles are clamped). It becomes possible. That is, it is possible to provide a clearance of about 80% of the clamping interval. Thus, in one rotation, for example, 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, 90% or more, 100% or more, 110 % or more, 120% or more, or 130% or more, either. There is no particular upper limit to the clearance provided in this manner as long as the operation can be easily performed, but practically it may be, for example, 9000% or less. If the pitch is too large, there is a risk that the tightening force due to pinching will not be sufficient. For example, the pitch/diameter ratio is 0.01 or greater, 0.1 or greater, 0.2 or greater, 0.3 or greater, 0.4 or greater, 0.5 or greater, 0.6 or greater, 0.7 or greater, or It may be anything from 0.8 or higher. Although there is no particular upper limit as long as the operation can be easily performed, such a ratio may be practically 3 or less, for example.

Figures 6, 7, and 10-15 illustrate several examples 32, 32a, 32b, 32c of lower receiving members that may be used with the adjustment device embodying the invention described above. FIG. 6 is a bottom view of a lower receiving member used as part of the alignment adjusting device, etc. of one embodiment of the present invention, and FIG. 7 is a BB cross-sectional view. As can be seen from these figures, the notch portion 34 provided in the lower receiving member 32 has a tapered shape that widens outward. Therefore, when the engaging member 18 inserted beyond the through-hole 35a is rotated 90 degrees to be engaged with the counterbored portion 35 and then further rotated 90 degrees to be released, the engaging member 18 can be easily pulled out. It's becoming FIG. 10 is a top plan view of another lower receiving member 32a for use with the face-to-face adjustment system of one embodiment of the present invention. As a whole, it has a substantially disc shape, but has a through hole 35b in a shape such as an ellipse, an ellipse, or a groove whose both ends are R-processed. The minimum width Da of the through hole 35b is greater than the length D of the engagement member 18 in the width direction and the diameter of the thin shaft 16 or the length corresponding to the diameter. Further, the length La of the through hole 35b in the longitudinal direction is larger than the length L of the engaging member 18 in the longitudinal direction, so that the engaging member 18 can pass through if the directions are aligned. By aligning the directions in this manner, the engaging member 18 and the thin shaft 16 can pass through the through hole 35b. Furthermore, by rotating the thin shaft 16 by approximately 90 degrees, the longitudinal length L corresponding to the engaging portion of the engaging member 18 becomes substantially perpendicular to the longitudinal direction of the through hole 35b. 35b, and is locked on the lower surface of the lower receiving member 32a. 11 is the same as the case of FIG. 10, except that the general shape of the lower receiving member 32b is substantially rectangular in plan view, and redundant description will be omitted. As described above, the lower receiving member 32 may have any shape other than a circular shape as long as it can contact the lower surfaces of the adjacent tiles. 12 to 15 show a plan view, a CC sectional view, a DD sectional view and a bottom view, respectively, of a lower receiving member 32c of another embodiment. The general shape is disc-like and similar to the embodiment of FIGS. The major difference is that four concave portions 33a, 33b, 33c, and 33d are provided on the flat upper surface, and the portions corresponding to the cutouts are wedge-shaped or isosceles triangular through-holes 34a when viewed from above. . Further, the central through hole 35a communicates with the aforementioned through hole 34a, and a groove-shaped engaging recess 37 into which the engaging member 18 can enter is provided. Furthermore, the ribs 38a and 38b are thin-walled and widen in a direction substantially perpendicular to the direction of the groove-shaped groove of the engaging recess 37, and substantially extend from the disk-shaped upper surface of the lower receiving member 32c. (that is, substantially parallel to the through-axis of the aforementioned through-hole 35a). The counterbore portion 35 is formed so that the counterbore surface includes the opening edge portion 37 a of the engaging recess portion 37 . By providing the concave portions 33a, 33b, 33c, and 33d in this way, it is possible to reduce the weight while maintaining the necessary strength. Since the disk shape, which is a rough shape, is maintained while facilitating the torsional rigidity, a high torsional rigidity can be maintained. Further, by arranging the rib portions 38a and 38b thinner than the joint width in the gaps (or joints) between the tiles, the rotation of the lower receiving member 32c can be prevented.

FIG. 8 is a partial enlarged view enlarging a part of the cross-section of the face-to-face adjustment device of another embodiment of the present invention. This drawing particularly shows the inner surface of the engagement moving member 22, the internal structure of the thick shaft 14, and the joined state of the thin shaft 16 and the thick shaft 14. FIG. In FIG. 1 and the like, the inner surface of the engaging and moving member 22 is threaded with a female thread. is formed as a hole (large inner diameter portion 25). The thick shaft 14 and the engaging moving member 22 are engaged by their respective externally threaded surface contours 20 and internally threaded inner surface contours 24, and rotate in response to the rotation of the engaging moving member 22 about the thick shaft 14. , but can move axially, the entire inner surface of the through hole of the engagement moving member 22 need not be threaded. Rather, it is preferable that a portion of the hole is simply a through-hole and does not participate in the engagement because the frictional resistance is lowered.

The thin shaft 16 is arranged such that its upper portion is embedded inside the thick shaft 14 . Further, the upper tip thereof is provided with a flattened flat portion 16a, which can relatively easily prevent the thin shaft 16 from relatively rotating inside the thick shaft 14. As shown in FIG. Furthermore, since the maximum width of the flat portion 16a is larger than the maximum diameter of the thin shaft, it is possible to prevent the flat portion 16a from being pulled out. Such a structure can be achieved, for example, by embedding a thin metal shaft 16 inside a thick shaft 14 made of synthetic resin, or by placing the thin shaft 16 in advance in a mold and inserting the synthetic resin into the mold using an injection molding machine. It can be formed by filling in a mold.

FIG. 9 is a partial enlarged view enlarging a part of the cross-section of the face-to-face adjustment device according to still another embodiment of the present invention. Here, it is an embodiment in which the threading of the female thread on the inner surface of the through-hole of the engaging moving member 22 is changed. Here, it is formed such that a part of the convex portion of the internal thread is removed (formation of partial internal thread). In this way, by reducing the contact area of the engaging portion, not only does the frictional resistance decrease and the rotation becomes smoother, but also if foreign matter is caught in the sliding surface, the foreign matter is removed from the sliding surface. It can also provide space to be accumulated, and can perform its function more stably.

Figures 16-28 show various engagement attachments that can be attached to the thin shaft of the alignment adjustment device of the present invention and how they are used. FIGS. 16-22 show examples of engagement attachments that engage engagement members 18 to allow the alignment adjuster 10 to accommodate larger or wider joints. 16 and 17 show an engagement attachment 70 comprising a pocket-like portion into which the engagement member 18 at the distal end of the thin shaft 16 can be inserted. The engagement attachment 70 has a rectangular parallelepiped or thick plate shape, and has a flat lower surface 71 on one side of the plate shape and a substantially rectangular opening 72a in the center thereof. An engagement recess 72 having a groove shape with a depth is provided. The engaging recess 72 extends longer than L in the longitudinal direction so that the engaging member 18 having a length L in the longitudinal direction and a length D in the width direction can be accommodated. is wider than D. Furthermore, the engaging member 18 may have a depth (equivalent to the length of the engaging member 18 in the height direction) that can be accommodated. The upper surface on the opposite side of the lower surface 71 is provided with an opening 74a of a slit portion 74 provided in the plate surface extending straight from the center in the longitudinal direction toward the lower surface, and round convex shapes 76, 76 like bumps on both sides thereof. . The slit portion 74 extends substantially perpendicularly to the longitudinal direction of the engaging recess 72 and communicates with the engaging recess 72 . The slit width of the slit portion 74 is equal to or larger than the diameter (or length corresponding to the diameter) of the thin shaft 16, and the thin shaft 16 can be inserted from the plate surface side opening 74b of the slit portion 74. I can guide you to 72. As described above, in the embodiment of the present invention, the engagement attachment has a length (equivalent to length L in the longitudinal direction of the engagement member) and a width (equivalent to length D in width direction of the engagement member). Since it is larger than the equivalent size of the joining member, it has a function of substantially expanding the engaging length (length L in the longitudinal direction) and width (length D in the width direction) of the engaging member. Figures 18 and 19 show a slightly different shaped engagement attachment 70a. The difference from the engaging attachment 70 described above is that the engaging concave portion 72 is open on one plate surface side. The opening 74c of the slit portion 74 also extends from the upper surface of the round convex shape to the engaging recess 72 without reaching the lower surface. With such a shape, as described below, the engaging member 18 can be put in and taken out relatively easily.

Figures 20-22 are perspective views showing how these engagement attachments 70, 70a are used. The thin shaft 16 and the engaging member 18 at the tip of the face-to-face adjustment device 10 shown in FIG. For convenience of display, the thin shaft 16 is drawn longer than it actually is. As shown in FIG. 20, the mating adjustment device is placed with the thin shaft 16 down, and the engagement attachment 70 is positioned so as to align with the centrally extending slit 74 and pushed in laterally relative to the axial direction. , the thin shaft 16 is inserted into the slit portion 74 . At this time, the engaging member 18 is located on the lower surface side, and is positioned directly below the opening 72 a of the engaging recess 72 beyond the lower surface 71 . When the thin shaft 16 is pulled upward, the engaging member 18 is accommodated in the engaging recess 72, and the upper surface of the engaging member 18 contacts the ceiling portion 78 corresponding to the bottom of the engaging recess 72. . In this manner, the engagement member 18 is received within the engagement recess 72 to restrict relative movement of the engagement attachment 70 axially upward and rotationally about the axis. The rounded convex shape of the upper surface 76 of the engagement attachment 70 abuts the lower surface of the tile as shown in FIG. Since the upper surface 76 has a rounded convex shape, it is difficult for the lower surface of the tile, which generally has many flat surfaces, to be uneven. In this way, by sandwiching the tiles between the upper surface 76 and the lower surface of the abutment member 30 and rotating and moving the engagement movement member 22 downward, the surfaces of the tiles 40a and 40b are aligned with the surfaces of the abutment member 30. The height is adjusted to the same height position based on the lower surface (see FIGS. 1 and 5). In this way, after the mortar 60 has cured and the tiles have adhered or adhered, the alignment adjusting device 10 is removed from the joint. Specifically, first, the engaging moving member 22 is reversely rotated to reduce the clamping force and create a sufficient clearance to release the tile. Then, force is applied from the head 12 or the like to further push the thin shaft 16 downward, thereby separating the engaging attachment 70 and the engaging member 18 from the lower surface of the tile, rotating the head 12, and referring to the direction of the projection 12a. Furthermore, by aligning the orientation of the engagement attachment 70 and the engagement member 18 with the orientation of the joint, the engagement attachment 70 at the tip of the thin shaft 16 and the engagement member 18 can be extracted from the joint. In addition, the head 12 and the like are rotated so that the engaging member 18 does not protrude from the engaging recess 72 of the engaging attachment 70 and the engaging attachment 70 does not remain in close contact with the lower surface of the tile. Preferably, the upper surface 76 of 70 separates first. Furthermore, even if the lower surface of the tile and the upper surface 76 of the engagement attachment 70 are fixed, the engagement member 18 can be rotated by rotating the head 12 or the like while being housed in the engagement recess 72. Then, by breaking (so-called threading) the connecting portion of the engaging member 18 with the thin shaft 16, the face alignment adjusting device 10 can be removed.

21 and 22 are different from the case of FIG. 20 in that an engaging attachment 70a having an engaging recess 72a opened on one plate surface side is used, and the rest are the same. Therefore, the alignment adjustment is performed as follows. The mating adjuster positions the thin shaft 16 downward, positions the engaging attachment 70a so as to align with the centrally extending slit portion 74, and pushes the thin shaft 16 laterally relative to the axial direction to slit the thin shaft 16. Insert into section 74 . At this time, although the engaging member 18 is on the lower surface side, it is arranged directly below the opening 72b of the engaging recess 72c even if it does not extend beyond the lower surface 71. As shown in FIG. When the thin shaft 16 is pulled upward, the engaging member 18 is accommodated in the engaging recess 72c, and the upper surface of the engaging member 18 contacts the ceiling portion 78a corresponding to the bottom of the engaging recess 72c. . In this manner, the engaging member 18 is housed within the engaging recess 72c and is restricted from relative movement axially upward and rotationally about the axis of the engaging attachment 70a. The rounded convex shape of the upper surface 76 of the engagement attachment 70a abuts the lower surface of the tile as shown in FIG. Again, as described above, the surfaces of the tiles 40a and 40b are height-adjusted to the same height position with respect to the lower surface of the contact member 30 (see FIGS. 1, 5, and 22). After the mortar 60 is cured, the surface alignment adjusting device 10 is similarly removed from the joint. Since the engagement member 18 is more easily released from the engagement recess 72c than in the above case, removal of the alignment adjustment device 10 is easier.

Figures 23-28 show another engagement attachment that can be attached to the fine shaft of the alignment adjustment device of the present invention and how it is used. Here we describe adjusting the surfaces of 3, 4, and more tiles simultaneously. Engagement attachments 70b, 70b' that can also be used at joint intersections where a plurality of tiles adjoin, as will be described later, and how they are used are shown. It can be used when the engaging member at the tip of the thin shaft 16 is a cross-shaped engaging member 18a, or when the engaging member 18 presents a straight line or a T shape together with the thin shaft 16. The engagement attachment 70b presents a cross shape (or cross shape) on its lower surface 71a, and an opening 72b' presenting a similar and contained smaller cross shape (or cross shape) in its surface. have. An upper surface 76a on the opposite side of the lower surface 71a is provided with round protruding shapes like biceps on the four cross-shaped arms, like the engaging attachments 70 and 70a described above. The cross-shaped (or cross-shaped) engaging recess 72d in bottom view has a width and length sufficient to accommodate the cross-shaped engaging member 18a. , a sufficient depth up to the ceiling portion 78b corresponding to the bottom. A through hole 75 is provided in the center of the engaging recess 72d. This through-hole 75 communicates with an opening 74d of a slit portion having a width allowing insertion of the thin shaft 16 from the side surface side. 24-26 show bottom, side and top views of an engaging attachment 70b' having a flat top surface 76a'. Other than that the top surface 76a' is flat, it is the same as the engaging attachment 70b described above, so redundant description will be omitted. Here also, the through-hole 75 has a rectangular shape when viewed from above, but may have a circular shape. FIG. 27 illustrates how such an engaging attachment 70b' is attached to a slender shaft 16 having a cross-shaped engaging member 18a at its distal end. The engaging member 18a is composed of four arms 18b radially extending from the center at substantially equal intervals. The engagement attachment 70b' receives the slender shaft 16 through its slit opening 74d. The four arms 18b at the tip of the thin shaft 16 are guided in respective openings 72b', and when the thin shaft 16 is pulled upward, it abuts against the ceiling portion 78b of the engaging recess 72d, thereby moving upward. , and rotation about the slender shaft 16 passing through the through hole 75 . In this way, the tiles are sandwiched between the upper surface 76a′ and the lower surface of the contact member 30, and the surfaces of the plurality of tiles are flush with the lower surface of the contact member 30, as in the case described above. adjusts the height of the tile surface. FIG. 28 shows how the same engagement attachment 70b' is attached to a thin shaft 16 having a T-shaped engagement member 18 at its tip. The two arms of the engaging member 18 are housed within two opposing openings 72b' of the engaging recess 72d of the engaging attachment 70b'. The details are the same as in the case described above, so overlapping descriptions will be omitted.

FIG. 29 shows a schematic diagram illustrating the alignment adjustment system using the alignment adjustment device of one embodiment of the present invention. First, an appropriate amount of mortar 60 is applied or arranged on the laying surface 50 at the laying positions of the tiles 40a and 40b, and the tiles 40a and 40b are laid thereon. Next, with the alignment adjustment device 10 as shown in FIG. The lower receiving member 32 is temporarily attached below the tile lower surface, and the contact member 30 is temporarily attached above the tile upper surface. Next, an appropriate amount of mortar 60 is applied or placed on the laying surface 50 at the positions of the tiles 40c and 40d, and the tiles 40c and 40d are laid thereon. At this time, the mortar 60 is not cured, and the tiles 40a, 40b, 40c, and 40d move downward by their own weights and the pressing force from the tile surfaces so as to crush the mortar 60. As shown in FIG. In this manner, four tiles 40a, 40b, 40c, and 40d are laid so as to form a cross-shaped joint (joint width Db). At the corners of the four tiles, which are the intersection positions of the cross-shaped joints, the lower receiving members 32 are arranged immediately below the tiles as shown in FIG. Next, as shown in FIGS. 2 and 3, the direction of the engaging member 18 at the tip of the thin shaft 16 protruding downward from the adjustment device 10 is aligned with the direction of the joint (joint width Db), and the adjacent tiles are separated. Insert from each joint of At this time, the diameter of the thin shaft 16 is smaller than the joint width Db. Next, the thin shaft 16 that has been inserted sufficiently deeply is rotated so that the engaging member 18 at the tip thereof can be engaged with the bottom surface of the adjacent tile or the counterbored portion 35 of the lower receiving member 32 . Incidentally, the provisionally attached adjusting device 10 has already been inserted in the place where the corners of the four tiles meet. Then, the engaging moving body 22 of the adjusting device 10 is rotated to press the surface of the adjacent tile against the lower surface of the abutting member, thereby matching the surfaces of the tiles so as to be aligned with each other. The same applies to where the corners of the four tiles abut against each other, but the presence of the lower receiving member 32 allows the four tiles to be sandwiched at the same time so that their surfaces can be aligned. After the time has passed for the mortar to have sufficient strength, the engaging movement 22 of the adjusting device 10 is rotated to relieve the pressing force on the tiles and against the projection 12a which serves as an indicator of the head. The direction of the engaging member 18 at the tip is aligned with the direction of the joint (joint width Db). By holding the head 12 and the like and pulling out the thin shaft 16 of the adjustment device 10 from the gap between the joint widths Db, it is possible to lay tiles whose surfaces are aligned. In such a system, the lower receiving member 32 can be provided only where it is needed, which is economical and efficient in construction.

FIG. 30 is the same as the case of FIG. 29 except that one side edge of each of the tiles 40a, 40b, 40c, and 40d is curved compared to the case of FIG. 29, so redundant description will be omitted. . The slender shaft 16 of the adjusting device of this embodiment of the invention is thin enough that even tiles with curved side edges can be inserted and withdrawn without problems. 29 and 30 illustrate joints such as intersections where four tiles are butted against each other, but joints where three tiles are butted against each other, as well as joints where five or more tiles are butted against each other. It should be understood that similar processing is possible with

FIG. 31 shows a procedure for mating tiles in which a lower receiving member 32c as shown in FIGS. 12 to 15 is applied to the adjusting device 10 as shown in FIG. FIG. 31 differs from the case of FIG. 29 only in that the adjusting device 10 is applied with a lower receiving member 32c shown in FIGS. Therefore, overlapping explanations are omitted. 1 between the tiles 40a and 40b. With the space left open, the lower receiving member 32c is temporarily attached to the lower surface of the tile, and the contact member 30 is temporarily attached to the upper surface of the tile. At this time, the rib portion 38a or 38b is inserted into the joint width Db between the tiles 40a and 40b. By doing so, the longitudinal direction of the groove 37 in which the engaging member 18 is locked becomes perpendicular to the joint, and the engaging member 18 can be easily pulled out from the joint. Next, an appropriate amount of mortar 60 is applied or placed on the laying surface 50 at the positions of the tiles 40c and 40d, and the tiles 40c and 40d are laid thereon. Since the mortar 60 is not cured, the tiles 40a, 40b, 40c, and 40d move downward due to their own weight and the pressing force from the tile surfaces so as to crush the mortar 60. As shown in FIG. Then, the fine shaft 16 of the adjustment device 10 is inserted through the joint between the adjacent tiles as described above and rotated approximately 90 degrees to engage the lower surface of the tile. Then, the engaging moving body 22 of the adjusting device 10 is rotated to press the surface of the adjacent tile against the lower surface of the abutting member, thereby matching the surfaces of the tiles so as to be aligned with each other.

FIG. 32 illustrates the procedure for aligning tiles using an adjusting device 10 such as that shown in FIG. 1 with engagement attachments such as those shown in FIGS. . First, an appropriate amount of mortar 60 is applied or arranged on the wall surface 52 to be laid at the position where the tile 41 is to be laid, first the side of the tile is placed on the surface corresponding to the floor, the tile is leaned, and then the tile is placed on the tile. A spacer 80 is provided, and the tile 41 is arranged on the spacer 80 so as to adhere or adhere to the mortar 60 of the wall surface 52 . In this manner, four tiles 41 form a cross-shaped joint, and two adjacent tiles 41 form a linear joint. Then, the direction of the engaging member 18 and the engaging attachments (70, 70a, 70b, 70b', etc.) at the tip of the thin shaft 16 projecting downward from the adjusting device 10 as shown in FIG. and insert from each joint and joint intersection. As a result, the upper surfaces (76, 76a, 76a', etc.) of the engaging attachments advance into the lower surface of the tile 41, and by rotating the thin shaft 16 by 45 degrees, the surface of the tile 41 touches the lower surface of the contact member 30. , the bottom surface of the tile 41 faces the top surface (76, 76a, 76a', etc.) of the engagement attachment. When the thin shaft 16 is to be inserted into a linear joint, by rotating the thin shaft 16 by 90 degrees, the surface of the tile 41 becomes the lower surface of the contact member 30, and the lower surface of the tile 41 becomes the upper surface of the engaging attachment (76, 76). 76a, 76a', etc.). Next, by tightening by the engaging moving member 22, the tiles 41 are held in contact with each other. In this way, the surfaces of the tiles are aligned so that they are aligned. After the time has passed for the mortar to have sufficient strength, the engaging movement 22 of the adjusting device 10 is rotated to relieve the pressing force on the tiles and against the projection 12a which serves as an indicator of the head. The direction of the engaging member 18 at the tip is aligned with the direction of the joint. Then, by holding the head 12 and the like, the fine shaft 16 of the adjusting device 10 is pulled out from between the joint widths together with the engaging member and the engaging attachment, thereby removing the surface alignment adjusting device 10 . At this time, even if the engaging member and the engaging attachment are fixed, the connecting portion between the engaging member 18 and the thin shaft 16 can be threaded by rotating the head 12 or the like. In general, when laying tiles (including panels, etc.) on a wall surface, mortar (including adhesive) is not applied to the entire back surface of the tile, but is applied partially or spotwise. Therefore, if there is a lower receiving member (for example, 32) on the lower surface side of the tile of the surface alignment adjustment device, when removing the surface alignment adjustment device 10, the space between the lower surface of the tile and the wall surface must be removed. may fall. As mentioned above, if the lower receiving member is not used, there is no such concern.
