- According to the present invention, it is provided a tool for, in particular manually, purging joints or grooves
-
- by means of removal of cementitious joint or groove material, especially in joints between tiles, panels, natural stone or mosaics, or
- for removal of joint or groove material, said removal being effective in terms of depth, in order to regrout, in particular without chemical admixtures or cleaning agents.
- Unlike conventional joint- or groove-scrapers, a stable and perceptible guide is obtained by the apposite guidance in the joint or groove, by the conical support of the abraded surface and by the soft bearing of the abrasive, in particular on a hard rubber base, in order to guarantee a fine and uniform removal of joint or groove material.
- According to a preferred embodiment of the present invention, the abrasive surface is glued and/or thermally, in particular thermoplastically, fixed at the respective rib.
- Alternatively, during the production process of the ribs the rear side of the abrasive area or grinding area can be melted into the surface by way of the so-called back injection method, thus sparing the adhesive technique. Also the ultrasonic wave method or ultrasonic welding can be used under ideal conditions.
- The working rib, having in particular a length of about 10 cm to about 14 cm, for example of about 11 cm or of about 13 cm, is a long-life precision tool which is also useful for improving deficiently done jointings.
- Correspondingly, the length of the abrasive area, in particular about 10 cm to about 14 cm, for example about 11 cm or about 13 cm, enables an apposite applying of the tool in the joint or groove and facilitates stable support in the joint or groove.
- The risk that the rib may slip off or burst out of the joint or groove is significantly reduced by the longitudinal extension of the rib. Due to the length and the stable support of the rib with its abrasive material it can be avoided that too much material is abraded and/or that material is abraded in an non-uniform way in terms of the extension of the joint or groove.
- In this context, the surface of the tool, in particular the abrasive surface, cannot become clogged due to the grain isles being distributed and dispersed on the surface.
- The main body or corpus of the instrument or of the tool may preferably be made of in form-foamed, harder or softer plastics, in particular of ethylene vinyl acetate (EVA) or polyethylene-based (PE), optionally with an amount of (natural) cork in the granule and/or optionally with colour(s) added.
- According to an advantageous improvement of the present invention the body or corpus may be produced by means of injection molding, i.e. hollow in its inner part and provided with a cover, for example with a back cover in terms of the working direction.
- Supplementally, the main body or corpus may be modified such that it comprises at least one air chamber facilitating a comfortable working and enabling the grinding pressure in any intensity.
- Independently thereof or in connection therewith, the main body or corpus may comprise a circumferential, in particular double, indentation with damping function.
- In an expedient improvement of the present invention the inner part of the main body or corpus may be provided with a sound-absorbing material, for example made of fleece, in order to enable a noise-reduced and thus more comfortable working.
- The handy main body or corpus may—not in the first place for reasons of design—may be slender or slim in order to be able to reach difficult-to-access regions. By the above-described damping, the subject-matter of the application gets at the same time a modern shaping and an excellent grip when using the tool.
- Furthermore an easy reception of ribs with different heights, with different widths, with different shapings and/or with different abrasive configurations may be enabled. Thereby, a slim or broad rib with easy clicking system, for example in the form of a buckle closure may be, depending on the requirements mounted, in a notch in the handle-type main part (=main body or corpus).
- Additionally, defining the working depth is enabled by providing such exchangable ribs with variabel heights for example of two millimetres, of three millimetres and of four millimetres. Providing such a exchange possibility for the abrasively provided rib has a synergetic effect in particular in connection with a damping, for example with one or two damping or buffer members in the handle-type main part.
- At one end or at both ends, the abrasively provided rib may slightly protrude beyond the handle-type main part in order to enable the user to see whether and, if yes, where the rib is situated in the joint to be treated. Such a protrusion of the rib beyond the handle part on one side or on both sides also enables a treating of difficult-to-access regions, for example of edge regions and/or of corners.
- The abrasively flocked rib enables a working under dry as well as moisty or wet conditions wherein the removal is higher in the latter case.
- Independently thereof or in connection therewith, the rib may advantageously be made of plastics, in particular of ethylene vinyl acetate (EVA), or of rubber, in particular of hard rubber.
- Independently thereof or in connection therewith, the abrasive area may expediently be
-
- galvanized as bort-provided surface of a substrate, for example on nickel areas, or
- of a ceramic splinter surface on a tissue carrier tape.
- The use of extremely hard materials such as diamond or ceramic in different grain sizes enables a continuous and fast working and guarantees a long lifetime so that the present invention provides a long-life precision tool by using premium industrial bort.
- In particular, the abrasive area may be formed of nickel-bound circular fields which are galvanically applied with bort in variable grain sizes, for example in categorized grain size 50 or in categorized grain size 60. The fields may diagonally run on the basis, in particular on a tissue or on a plastic adhesive surface, namely in particular in a small distance to the respectively next field.
- In an alternative embodiment, the abrasive area may be diamond-flocked continuously and/or with varying distances between the single grinding modules.
- In an embodiment alternative to the abrasive area, the rib may be provided in a joint- or groove brush way with brush material comprising harder or softer bristles, for example of a length of about two millimetres to about four millimetres.
- Basically, in a preferred embodiment of the present invention working ribs of different heights and/or of different widths are provided depending on the depth, width and/or hardness of the joint or groove wherein the grain of the abrasive area of the working rib is variabel.
- According to an expedient improvement of the present invention, the rib may be embodied in different heigths and may, depending on the requirements of the joint width, be coated in thin stripes having a width of about two millimetres to about five millimetres, for example with long stripes, be it continuously coated or disruptively coated (at the circular fields: for example about 0.5 mm distance to the next field).
- The correspondingly formed slim working area is thus bort-provided or similarly abrasive and either continuously coated or provided with disruptively coated fields in order to enable the removal of the abraded material between the single fields.
- Alternatively or supplementally, a small dust bag or dust collector or vacuum cleaner may be allocated to the subject-matter of the application in order to catch the accumulating dirt or dust when abrading joint or groove material.
- Different selecting options concerning the width of the abrasive grinding working area provide an apposite support in the joint picture. Manually conducted, the total joint width may be treated in one draw. The effect is a quick and clean abrading of the desired area and joint depth.
- The rib provided with the abrasive area is preferably formed of elastic, slightly resilient material in order to be able to choose the grinding pressure on the area to be treated individually and depending on the requirements:
- On the one hand, an uncontrolled removal of joint material is thus avoided; on the other hand, the risk is thereby reduced that ceramic material, glaze, glass or natural stone surfaces adjacent to the joint or groove or generally adjacent materials are damaged.
- The front end of the rib and/or the back end of the abrasively provided rib may be slanted or angled, for example by 45 degrees, or bent, for example circular, or curved:
- By this, it is on the one hand avoided that the abrasive area may be quickly pulled off; thus, the lifetime of the tool is increased. On the other hand, the work in corners and at the end of the treated joint, for example in room corners or connections to silicon joints, is improved by this technical measure. The slanted edges may also be provided with abrasive area.
- Such an expediently slightly conical embodiment of the rib on the main body or corpus additionally facilitates the apposite applying in the joint or groove. In addition, when applying into the joint or groove, certainty is obtained in the side view that the tool is exactly applied in the joint or groove and/or is exactly born there when starting work.
- Since the abrasive area, including the rib becoming slightly narrower in the tool's part more to the front, is plunged in the joint or groove when gently pressed down, the thus effected secure guidance reduces the risk to slide out of the joint or groove. By this contact between the main body or corpus and the surrounding material, for example on the surface of a tile or of a natural stone, a lateral or sidewise lurching of the tool in the joint or groove is avoided.
- The main body or corpus thus slides without tottering through the joint or groove and thus gives a perceivable feeling of working safety. This facilitates inter alia the remarkably higher working speed compared to other joint or groove cleaning methods as well as the more proper result.
- For regions, such as for example mounted shower bars, corners with oblique angles or diagonally installed floorings, it may be possible not to get into the joints or joint corners with the tool or not to reach the end of the joint. Therefor, a further instrument may be added to the product contents:
- This very simple hand instrument in the form of a pen with the size of about a plastic or metal pencil ends in a ball sitting in a ball bearing. A rib of hard plastic, provided with abrasive area like at the actual tool, is fixed at this ball bearing, in the same style but without any soft support. Therewith, any difficult-to-reach regions are reached. Here it is possible to design the rib at the ball bearing in an exchangable manner and to offer differently abrasive stripes. The pen may be obtained as additional tool or may be added to the actual device according to the present invention.
- The present invention provides manifold application and use possibilities:
-
- extensive removal or cleaning of joints up to a depth of about five millimetres
- >possibility to regrout tile areas;
- when selecting a higher rib, joint or groove material up to the respectively required depth may be abraded in order to enable regrout work; here, there is the possibility to deliver a joint colour card;
- scratching out parting lines and movement joints, vertically and horizontally;
- reworking scruffy joint or groove works;
- abrading of protrusions of joint or groove material;
- levelling of joints or grooves;
- cleaning of mosaics or groove tiles, for example steps with milled-in notch, or the like;
- scratching out of rests of adhesives.
- extensive removal or cleaning of joints up to a depth of about five millimetres
- The subject-matter of the application may also be operated electrically, for example by mounting the abrasive (changable) area by means of the rib on an oscillating or back-and-forth moving installation in the main body or corpus.

FIG. 1A toFIG. 4C . - In order to avoid unnecessary repetitions, the explanations below relate to
-
- the first exemplary embodiment of the present invention illustrated on the basis of
FIG. 1A toFIG. 1D , - the second exemplary embodiment of the present invention illustrated on the basis of
FIG. 2A toFIG. 2E , - the third exemplary embodiment of the present invention illustrated on the basis of
FIG. 3A toFIG. 3F , and - the fourth exemplary embodiment of the present invention illustrated on the basis of
FIG. 4A toFIG. 4C - with respect to the configurations, features and advantages of the present invention—unless otherwise indicated.
- the first exemplary embodiment of the present invention illustrated on the basis of
- The
device 100 illustrated on the basis ofFIG. 1A toFIG. 4C serves to abrade or remove material from a joint or groove by means of anabrasive area 30 provided at arib 20, saidrib 20 being allocated to amain body 10 embodied as a wedge or a three-dimensional trapezium. - For damping purposes, the
main body 10 comprises in its inner part twoair chambers 12 according to the first exemplary embodiment (cf.FIG. 1A toFIG. 1D ). Alternatively, themain body 10 comprises on its outside for damping purposes twocircumferential indentations 14 according to the second exemplary embodiment (cf.FIG. 2A toFIG. 2E ). - The side of the
abrasive area 30 which is averted from the joint or groove can be melted into the surface of therib 20, for example by means of ultrasonic welding. Alternatively, the side of theabrasive area 30 which is averted from the joint or groove can be glued and/or thermally, in particular thermoplastically, fixed at therib 20. - The
abrasive area 30 of therib 20 is embodied as a substrate, in particular a tissue carrier tape, which is at least sectionally or at least partially provided with abrasive material, in particular with bort and/or with ceramic splinters, wherein the abrasive material can be arranged isle- or field-wise on theabrasive area 30 in order that the abraded or removed material can be dispatched between the respective isles or fields. - The third exemplary embodiment according to
FIG. 3A toFIG. 3F comprises anexchangable rib 20. Therefor, the essentially T-shapedrib 20 is inserted into a notch-type recess 16 of themain body 10, saidrecess 16 being embodied as a receptive shaft. The region of therib 20 which is averted from theabrasive area 30 is disengageably fixed in therecess 16 of themain body 10 in a form-fitting way. - As can be taken in particular from the detailed view in
FIG. 3D , the side of therib 20 which is averted from theabrasive area 30 comprises at its, in terms of the working direction, front end a snap-innose 22, said side being embodied as elastically mounted tongue within an isolated area. The snap-innose 22 engages into a notch 18 (to the left inFIG. 3B ) provided in therecess 16 when therib 20 is inserted in therecess 16, saidnotch 18 being embodied as transverse furrow. - The
rib 20 can be disengaged, namely pulled out of therecess 16, by pressing afluted region 24 at the, in terms of the working direction, front end of therib 20, saidregion 24 being adjacent to the snap-innose 22, for example for inserting and fixing another or a fresh ornew rib 20 in therecess 16. - By means of the snap-in
nose 22, it can also be avoided that therib 20 is inserted into therecess 16 in the wrong direction. For avoiding such maloperation, therib 20 may be provided with at least one marking, for example with at least one arrow, indicating the correct insertion direction. - In order to be able to better grasp the
fluted region 24, saidfluted region 24 protrudes beyond themain body 10 at the, in terms of the working direction, front end of therib 20 when therib 20 is inserted in therecess 16. - As a result, the third exemplary embodiment according to
FIG. 3A toFIG. 3F thus discloses the possibility to replace or change therib 20 assigned to themain corpus 10 which is enabled by the form-fitting reception of the rib 20 (cf.FIG. 3C toFIG. 3F ) in the essentially T-shaped recess (=receptive shaft 16) of the main corpus 10 (cf.FIG. 3A andFIG. 3B ). - In the fourth exemplary embodiment according to
FIG. 4A toFIG. 4C , the option is illustrated to exchange theabrasive area 30 at therib 20 by means of a clamp-like clickingsystem 28. - 100 device
