Description

The invention relates to a crosshairs for defining joints when laying tiles or plates.

A Fugenkreuz, as the invention does not exclusively, but also in particular is known from DE 44 39 647 CE. The crosshairs are used to define Joints when laying tiles, for example using the adhesive process. It points four perpendicular to each other legs that have a width corresponding to the Have joint width between the tiles. There is a handle on the thighs molded in one piece, which is perpendicular to two opposite legs of the Fugenkreuzes extends. To define a smaller, second joint width are pin-shaped Approaches near the free ends of the legs on the remote from the handle Areas provided. There is one on at least one of the four legs of the Fugenkreuzes predetermined breaking point provided by indentation.

The object of the invention is to provide a versatile and inexpensive Fugenkreuz create.

The invention relates to a crosshairs for defining joints when laying tiles or plates with at least three legs that are angled in a common foot area protrude from each other and each have a pass width that a joint width between the tiles or plates.

The Fugenkreuz is preferably made in one piece from plastic and is preferably used for laying in an adhesive process or mortar process. Preferably stands the first leg at right angles from each of the other two legs, so that the Fugenkreuz has the shape of a "T". After canceling, the two remain in the other leg lying in flight, which is still a fitting piece for training can form a joint in the pass width. In a preferred embodiment the Fugenkreuz four, at right angles to each other, and it will by breaking off the first leg, a T-shaped crosshair for the formation of a Preserved T-joint.

According to the invention, a cavity is formed in at least one of the legs. By Formation of the cavity saves material. If the plastic crosshairs in a plastic casting process is produced, as is preferred, in particular in an injection molding process, because of the cavity, the cooling time and thus the service life reduced in the tool compared to a solid material leg.

The cavity is preferably used to form a plug-in connection with another joint cross, on which a plug-in extension is formed for this. The other crosshairs are preferred formed according to one of the claims. However, it can also be done in principle another crosshairs are formed. In particular, it can by a generic Fugenkreuzes are formed, advantageously other related Features disclosed the invention are realized.

The cross section of the cavity and the cross section of the plug-in extension are preferred for Formation of a purely frictional plug connection adapted shaped. Preferably are their cross-sections of the same shape, the cavity having a small excess, so that the plug-in extension fits snugly in the cavity, but is easily inserted into the cavity and can be pulled out again without risk of damage. In one preferred embodiment, the one cross has several for a connector shaped cavities adapted to a plug-in extension in another preferred Embodiment has the other Fugenkreuz several for a connector with a cavity shaped molded extensions on even more preferred a crosshair has one or more cavities and one or more plug-in extensions at the same time.

The joint crosses are particularly suitable for assembling a large number of joint crosses to a figure, for example an animal figure, which promotes sales in a sales room the attention of potential customers to themselves and thus to the joints judges. The ability to plug together several Fugenkreuzes also makes it easier Handling when laying the tiles or the storage of the joint crosses. For example, individual crosshairs can be lost less easily.

The at least one cavity is preferably formed in a thickening of the leg. The exact laying of the tiles or panels is helpful if one Leg of the crosshair is not even in the width of the pass width, but has a thickening in the pass width. The thickening defines the pass width of the thigh. Since the leg is thus withdrawn from the thickening Has areas, the adhesive, generally an adhesive or mortar, in addition to the Thickening in the withdrawn area or multiple withdrawn areas Exit areas of the joint past the joint when the joint cross is positioned becomes. If namely the one usually applied before laying the tiles Adhesive is not applied evenly thick, it can be in a place where a Fugenkreuz is positioned, accumulations of the adhesive come into which the Fugenkreuz is pushed in in such a case. By training one only in certain areas Fitting cross joint width is prevented from being displaced by the Fugenkreuz Adhesive is pressed under adjacent tiles or plates and discard them can.

A cavity formed in such a thickening is hereinafter referred to as a cavity of the first kind or simply called the first cave.

The thickening described above is preferably in training in a cross section the rounding is cylindrical. It is particularly preferred in a further development of the cavity hollow cylindrical. The thickening can be with a continuous cavity or just one be open cavity on one side of the thickening.

Although the advantage in terms of positioning is basically already through training Such a thickening can be achieved on only one leg, since the adhesive at least in its area can escape to the outside, all are preferred Leg of the Fugenkreuzes with at least one thickening in the pass width of each Provide thighs, preferably the fit width for all thighs is the same. The fit width of each leg is preferably thickened or several thickenings arranged one behind the other in the longitudinal direction of the leg educated.

In a particularly preferred exemplary embodiment, one forms the pass width of one Thigh defining thickening of the type described above a free end of this Thigh.

The thickening is preferably rounded. It is particularly preferred on all sides until Leaking rounded in a recessed thigh area. Through this design a linear shock, i.e. a linear system, for the tiles or slabs formed. A line-shaped bump can, in principle, if less preferred to be formed by an edge.

By forming the pass width in the form of one or more thickenings and in particular by forming an attachment to the tiles as a line Unevenness in the tile edges is compensated or at least disturbs much less than with flat system over the length or a substantial part of the length of a leg.

In a preferred exemplary embodiment, lugs protrude from the legs a plane spanned by the legs. The approaches each have a pass width, which corresponds to a joint width between the tiles or slabs and smaller than that Is the width of the thigh. Through this formation of the Fugenkreuzes, which as such DE 44 39 647 CE is known, joints can be in two different, defined Widths are formed.

In one development, the approaches have chamfered outer edges at their free front ends. In a first embodiment, the approaches are straight cylindrical and only in chamfered its end area. In another embodiment, the approaches are large Part of its length is conical towards its free ends. To their respective Thighs, however, run straight cylindrical. Through the chamfered outer edge or The conical shape of the lugs makes it particularly easy to insert into the joint. Further pulling out the crosshairs from the adhesive is made easier because the adhesive adheres less firmly than to blunt roots. Finally, the chamfering of the lugs also helps to a material saving.

At least one of the approaches, which can advantageously be chamfered, has one Cross-section based on a cross-section of a cavity in one of the legs of another Fugenkreuzes is insertable and frictionally in the cavity after insertion is held. It can therefore be the frictional connection between two or more Joint crosses are formed. The cavity or preferably several cavities are expedient for establishing the plug connection to one of the approaches facing side of the crosshairs open. The approaches are particularly preferred or at least one approach for a plug connection with the or the at least one first cavity.

In another preferred development, a grip piece protrudes from the legs has a free outer contour between two gripping surfaces, which is at least a distance runs perpendicular or almost perpendicular to a plane spanned by the legs.

In particular, the outer contour in this piece has a support in one Angle perpendicular to the plane that is less than ten degrees. Through this shape and Alignment of the outer contour, it is possible to use the handle as a support for a spirit level to use. A spirit level can thus be on just two handles of two in the horizontal tile crosses spaced apart from each other and otherwise placed freely become.

In another development, at least one of the legs has a second cavity The second cavity is preferably elongated. It preferably extends over two Leg. In particular, it extends over the two legs on which the first Thigh attaches. If one or more first cavities are formed, it extends the second cavity close to the first cavity or cavities in the two legs. It is preferably open to an underside of the crosshairs. The second cavity is preferably designed as a straight, simple longitudinal groove. You can also benefit be designed as a through slot. It is preferably symmetrical with respect to one The central longitudinal axis of the leg (s) hollowed in this way is arranged.

In the second cavity, a handle of another cross joint can advantageously be included. Although preferred, the removable handle must be do not act as a handle with an outer contour of the type described above. The outer contour can basically also form a slope, as is the case with the Fugenkreuz DE 44 39 647 C2 is the case on which a freely lying spirit level slips. However, a handle with an outer contour, of which a spirit level is preferred does not slip without external influence.

The second cavity and the handle preferably have such a match Cross sections on that the grip in the second cavity after inserting it frictionally is held, i.e. a frictional connection between the second cavity and the handle Plug connection is formed.

The second cavity may be the only cavity in the at least one leg or one form another cavity to the cavity in a thickening. Likewise, the cavity in a thickening may be the only cavity or type of cavity. The combination of the two Cavities or types of cavities are preferred.

A single approach or multiple approaches can or can be the plug-in extension or the Form plug-in extensions. The handle alone can be the plug extension of the described Kind of make up. The plug connection formed by means of the second cavity and the handle Like the approach (s), the only way to put together form two or more crosses. A combination of is particularly preferred two plug-in extensions and also of both options for a plug connection.

In preferred exemplary embodiments, a first leg is one of the at least three legs tapered towards the foot area, creating a predetermined breaking point to the other two Thighs is formed. In a further development according to the invention, each of the two other leg at the predetermined breaking point withdrawn behind its pass width. Hereby it is ensured that after breaking off the first leg one at the predetermined breaking point Possibly the remaining piece of material does not exceed the level of the pass width line or pass width level can stand, which the Fugenkreuz on the side of Breakage point forms.

Immediately at the predetermined breaking point is preferably only that leg that has broken off should be tapered to achieve a notch effect, for example vertically or preferably undercut straight at an angle to a longitudinal axis of this leg. The the first leg can preferably also bulge into the predetermined breaking point, which makes a point in the foot area with a very acute angle and therefore a special one well-defined breaking point is created. Since the other two legs, to which the A predetermined breaking point is formed, preferably no notch in the area of the predetermined breaking point have, the predetermined breaking point is formed even more precisely on the first leg. Ultimately unavoidable pieces of material, which after breaking off in the area of In this way, the predetermined breaking point protruding from the other two legs kept as small as possible.

The configuration of the predetermined breaking point in accordance with the invention makes it possible to withdraw one Area and thus also a thickening in the aforementioned sense on the two Formed legs, from which the breakable first leg protrudes.

The thickening feature is particularly preferred in combination with that of the invention Cave realized. But also a crosshairs according to the generic term of Claim d. H. Without a cavity, one or more thickenings of the above can advantageously be used have described type. Such a crosshairs for fixing joints when laying tiles accordingly has at least three legs that protrude at an angle from each other in a common foot area and one pass width each have a joint width between the tiles. At least one the leg of this crosshair has a thickening in the pass width.

A crosshairs only with the feature a) of claim 1 and in particular in combination with one or more of the features of the chamfering of at least one approach, the outer contour of the handle and the shape of the slot in the handle represents one represents a particularly advantageous embodiment of a Fugenkreuzes, which by means of further in the Registration of disclosed features can still be improved. The applicant retains to direct yourself to one or more divisional registrations.

Fig. 1 shows a crosshairs in a perspective view of an upper side of the crosshairs towards a wall, which is not shown. Fig. 2 shows that same crosshairs in a perspective opposite view towards an underside of the crosshairs.

The Fugenkreuz comprises four legs 1, 2, 3 and 4 with lugs 12 and a handle 14. The crosshairs are made in one piece from plastic in an injection molding process.

The four legs 1-4 protrude from a common foot area or crossing area perpendicular and rigid from each other. They span a plane in their right angles on. A circular cylindrical extension 12 projects from each of the legs 1 - 4 from the underside of the respective leg perpendicular to the leg plane. The handle 14 protrudes from the top of the legs 1-4 also perpendicular to the leg plane. The two Legs 2 and 3 point along a common central longitudinal axis, which is a first axis of symmetry of the Fugenkreuzes, away from the common foot area and form a fixed cross body. The two legs 1 and 4 protrude along one common, second central longitudinal axis from the common foot area from each other path. The second central longitudinal axis forms a perpendicular to the first axis of symmetry second axis of symmetry of the Fugenkreuzes. The crosshairs as a whole are axially symmetrical with respect to the two axes of symmetry.

The two legs 1 and 4 are each via a predetermined breaking point 5 to by the two other legs 2 and 3 formed solid cross body. The predetermined breaking point 5 is formed by an imaginary connecting line between two notch tips. In the notch tips or the predetermined breaking point 5 the leg 1 sets on the two legs 2 and 3 on. The two legs 2 and 3 are in turn not in the area of the predetermined breaking point 5 notched. In the exemplary embodiment, leg 2 and leg 3 each run with axially parallel, planar surface areas 9 into the respective notch base. Another The course of the two surface areas 9 would also be conceivable, but an acute one should be Notch reason can be guaranteed to the predetermined breaking point 5 in the desired shape, such as shown with a dotted line. A notch effect on the part of the two However, legs 2 and 3 should also have a different shape of the two surface areas 9 be avoided. The leg 1, however, is in its cross section towards the notch base rejuvenated. In the exemplary embodiment, it runs tapered on both sides at an angle Notch reason. To give a particularly pointed and therefore particularly well-defined notch base the tapering could also be achieved by a bulged shape of the Leg 1 are formed on his thigh foot. The notch base runs perpendicular to Longitudinal axis of legs 2 and 3.

The predetermined breaking point 5 lies completely behind a tangent or tangential plane on the long side walls of the two legs 2 and 3. The withdrawn Surface areas 9 of the legs 2 and 3 form relative to such an enveloping tangent or tangent plane a withdrawn area. If the leg 1 for training of a T-shaped crosshair is broken off at its predetermined breaking point 5, so by this arrangement of the predetermined breaking point 5 safely avoided that after canceling not entirely avoidable piece of material that at the break-off point of the Legs 2 and 3 protrude, protrude beyond the imaginary tangent or tangential plane. For the opposite leg 4 a predetermined breaking point 5 is formed in the same way, as can be seen in Fig. 2.

In Fig. 2 are representative of all legs 1 to 4 for one of these legs two Widths B1 and B2 entered. The widths B1 and B2 define the width of one when in use of the Fugenkreuzes joint and are therefore in the following as pass widths designated. The legs 1-4 define a first pass width B1 and the molded Approaches 12 have a smaller, second pass width B2. By plugging in of the Fugenkreuzes only up to the underside of the legs 1 - 4, the joint width by the Approaches 12 defined. The tiles that form the joint between them abut the approaches 12 and therefore have the joint width B2 between them. Should the joint width B1, legs 1-4 are also pressed into the adhesive. In this In this case, the joints or panels hit the side surfaces of the legs 1-4, and it becomes the Obtain joint width B1. The side walls of legs 1-4 are straight and all face perpendicular to the plane spanned by legs 1-4. The imaginary tangential planes on the two long sides of each of the legs 1-4 are plane-parallel. Your distance corresponds to pass width B1.

Each of the legs 1-4 has two round one behind the other in the direction of its longitudinal axis outward bulges 6 and 7, between which a withdrawn Area 8 is formed in the manner of a constriction. The thickening 6 forms in each case the rounded free end of each of the legs 1-4. The thickenings 6 and 7 of the Legs 1-4 should be cylindrical, in the exemplary embodiment they are circular cylindrical. By rounded in the area of the thickening 6 and 7 to the imaginary tangential planes bulging shape of these thickenings 6 and 7 result in linear supports or Lines of abutment for the tiles or plates abutting the thickenings 6 and 7. Bumps This compensates for the edges of the tiles. By the withdrawn areas 8 and 9 or the notch of the legs 1 and 4 Space for the adhesive was created. When pushing the crosshairs into the adhesive swells displaced adhesive in the area of the withdrawn areas 8 and 9 and of the notch base to the outside and can be easily removed there. By the relieved Escape of the adhesive mass is prevented that the displaced adhesive mass below the neighboring Tiles or slabs can be pressed, thereby warping the tiles or plates. Furthermore, the pull-out force for pulling out the crosshairs reduced from the joint. A material saving also results from the Definition of the pass width B1 by means of the thickenings 6 and 7, namely in comparison to Legs that are made over the entire length in the pass width B1. Finally minimize the curves and the reset of the predetermined breaking points 5 the risk of injury on any sharp edges, and it can break off due to the curves perform easier and more pleasant.

The lugs 12 are straight cylindrical over most of their lengths. At their free At the ends, however, they are provided with a circumferentially chamfered outer edge 13. At the free Ends of the lugs 12 thus form truncated cones. By chamfering the outer edges insertion into the adhesive is facilitated. Furthermore, the chamfering Pull-out force when pulling out the crosshairs compared to a blunt end of approaches 12 reduced. By chamfering, material becomes for them Production of the joint cross saved, the truncated cone area with the chamfered outer edge 13 also extended compared to the embodiment in the embodiment and thus the potential for material savings can be increased.

The legs 1-4 are provided with cavities. This results in a material saving compared to a Fugenkreuz made of solid material. In particular, the cooling time and thus reduces the tool life of the crosshairs. Through the Reducing the tool life results in an increase in productivity per tool and thus a reduction in manufacturing costs.

First cavities 10 can be seen in FIG. 1. A first cavity 10 is in each of the Thickenings 6 are formed, on which the lugs 12 are molded. The first caves 10 each have the shape of a circular cylindrical bore. They either end in the kind of a blind bore in the thickenings 6 or are in the approaches 12 extended. Each of the cavities 10 can also be formed with a large offset Cross-sectional area in the area of the thickening 6 and a smaller cross-sectional area in the respective approach 12.

The cross section of each of the cavities 10 is in a first embodiment on the Cross-section of the lugs 12 of the same Fugenkreuzes adjusted so that each of the Approaches 12 can be inserted into each of the cavities 10 and in the inserted Condition frictionally and releasably held in it. By placing two crosses a frictional plug-in connection by means of a cavity 10 of a crosshairs and an approach 12 of another Fugenkreuzes can be made and because of the additional Variety of variations due to the multiple cavities 10 per joint cross and lugs 12, it is possible to put together a plurality of joint crosses to form a figure of any size, for example an animal figure, with crosses. Such a figure can be exhibited as a promotional measure in a sales room to attract the attention of potential buyers to the rather nondescript itself Straighten crosses. With crosshairs in different shades, the appearance can such a figure can be designed particularly appealing.

Cross-overs in different sizes, in particular in different sizes, are preferred Pass widths, provided, and it will be each of the sizes in a different Hue offered. In a second embodiment variant, a cavity 10 of a Fugenkreuzes of a first size for the production of a connector with a Approach 12 of a crosshair of a different, smaller size can be formed multicolored figure can be put together.

The cavities 10 and the lugs 12 can be designed so that the crosshairs same size can be put together, what by training the cavity 10 in the thickening 6 is easily possible. The cavities 10 and the lugs 12 can also have cross-sections that are only for plug connections of joint crosses are suitable in different sizes, for example if one is simple straight cylindrical cavity should protrude into an extension 12. Through a cave 10 with a larger cross section in the area of the thickening 6 and a smaller cross section in approach 12 are frictional plug connections of crosses in different Sizes can be manufactured.

In Fig. 2 it can be seen that the joint cross body formed by the two legs 2 and 3 with a second cavity 11 in the form of a straight, parallel-walled longitudinal groove is provided. If a handle 14 is not provided on the top of the crosshairs is and the two legs 2 and 3 are made sufficiently wide, the second Hollow 11 can also be enlarged to a through slot. The one from the legs 2 and 3 formed Fugenkreuzkorpus encloses the training as a through slot formed second cavity box-shaped. A rounded through slot would be equally feasible. One advantage is that such a crosshair for staying in the joint is particularly suitable. After defining the joint, d. H. after fulfilling its primary Task, such a crosshairs can easily be smeared with a grout. The Grout takes place despite the crosshairs or even because of the trained Fugenkreuzes a secure hold in the joint.

As is also preferred, however, the Fugenkreuz has on its top Handle 14 on to easily remove the cross after the formation of the joint Pull out the adhesive and use it again. Basically, however, it would be possible to leave a crosshair in the joint without a handle. Training the Handle 14, however, brings a whole series of more practical than the gripping possible Benefits.

The handle 14 has the shape of a thin plate with two opposite one another Grip surfaces. It can be gripped firmly between two fingers. In a medium range the handle 14 is provided with a slot 15. The slot 15 extends from an outer contour 16 formed between the two gripping surfaces perpendicular to that of the legs 1 - 4 spanned plane. A guideline can be inserted into the slot 15 become. To do this, position the crosshairs in the joint so that the two Legs 2 and 3 and thus the handle 14 form the vertical. With two like that in one Horizontal spaced crosses can be horizontal To be stretched. The guide line with a knot at one end is in the slot 15 of one crosshair clamped in and through the slot 15 of the other Fugenkreuzes pulled and tensioned. The pulled through the latter slot 15 The guide line is passed through the notch base of leg 1 or 4 behind it and wrapped around this leg 1 or 4 and attached so. Should the thigh in Formation of a T-shaped crosshairs have been broken off, the guideline can are wound around one of the legs 2 and 3 and fastened in this way. In any case the guide line comes due to the thickening 6 and 7 within a withdrawn Area 9 or to lie in the two notch reasons of one of the legs 1 and 4 and therefore does not apply.

The mutually facing, long edges of the slot 15 point perpendicular to that of the leg spanned plane or at an angle of less than 10 °, preferably less than 5 ° to the perpendicular to the thigh level, so that it is prevented even more securely the guide line, especially the end with the knot, comes out of the slot 15 slips out.

The outer contour 16 points at least a little way from the top of the crosshairs perpendicular or almost perpendicular to the plane spanned by the legs 1-4. This course of the contour 16 makes it possible to position two spaced apart Fugenkreuzzen or on the handles 14 a spirit level in the horizontal align. In particular, the spirit level remains due to the shape of the outer contour 16 lie on the two handles 14 and does not slip away from the wall from the grips 14. The user must position the spirit level for exact positioning the crosshairs do not permanently press against the crosshairs in the horizontal, on the one hand to ensure the accuracy of the alignment and on the other hand a To prevent the spirit level from sliding down. One to reduce a notch effect possibly existing slope of the outer contour 16 is in the area in which a spirit level is put on, in any case not greater than 10 degrees to the vertical the plane spanned by the legs 1 -4.

Finally, the shape of the second cavity 11 and the Grip 14 receive a second frictional connector for two crosses. At least the second cavity 11 can accommodate a handle 14. The second cavity 11 and the handle 14 are provided in alignment on the crosshairs. This second Possibility of putting joint crosses together is particularly practical Handling of interest. Thus, by means of the cavities 11 and the grips 14 joint crosses put together to form a straight stack are easier to handle as a loose variety of the same crosshairs.

The slot 15 points over its entire edge area to each of the two gripping surfaces towards a chamfered edge 17. In the exemplary embodiment, the beveling of the edge 17 formed as a landing. By chamfering the edge 17, one end of the Guide with the said knot held more securely in the bottom of the slot 15. Furthermore this results in further material savings.

3 and 4 show crosses with all the features of the embodiment 1 and 2, but in a different size. The pass widths B1 and B2 of the Fugenkreuzes 3 and 4 are larger than those of the embodiment of FIG. 1st and 2. The cavities 10 and 11 and the handle 14 of the cross joint of FIGS. 3 and 4 and at least the concavity 11 and the grip 14 of the cross joint of FIGS. 1 and 2 are designed such that the crosshair of FIGS. 1 and 2 and the crosshair of FIG. 3 and 4 plugged together by means of the two plug connections described above can be.

5 and 6 finally show a further crosshair in a third size. The The crosshairs of FIGS. 5 and 6 have smaller pass widths B1 and B2 than that of FIG. 1 and 2 on. Furthermore, the crosshair of FIGS. 5 and 6 does not have the second Cavity 11, because its pass width B1 is already so small that a short cooling and standing time is given in the mold from home. In the other design features however, it corresponds to the crosshairs of FIGS. 1 to 4.
