Description

[0001] The invention relates to a laying tool for floor coverings with a support element, a guide element and a bolt element.

[0002] Floor coverings are typically installed floating. When installing floor coverings, which are often connected to each other using a tongue-and-groove joint, it is important to avoid gaps between the individual floor coverings. For this reason, the individual floor coverings must be firmly joined together.

[0003] For example, the use of a pull bar is known from the prior art, with one angled end of the pull bar gripping behind the edge of a floor covering. Furthermore, another, oppositely angled free end is formed at the other free end, which serves as a stop for, for example, a hammer.

[0004] Alternatively, the floor coverings can be joined using a tapping block and a hammer. A tapping block has a contact surface adapted to the tongue-and-groove joint.

[0005] A disadvantage of the existing devices, however, is that they are only suitable for predetermined, constant floor covering material thicknesses. Accordingly, different tapping blocks and / or pull bars are required for different material thicknesses. Another disadvantage is that a separate tool, usually a hammer, is required. Furthermore, the corresponding device is very loud during use due to the hammer blows, which usually hit wood or iron. Furthermore, a pull bar can only exert a tensile force on the respective floor covering, while a tapping block can only exert a compressive force.

[0006] The invention is therefore based on the object of providing a laying tool for floor coverings which can be used for different material thicknesses of the floor coverings, minimizes the risk of injury, reduces noise during use and makes other tools obsolete.

[0007] This problem is solved by the combination of features according to patent claim 1.

[0008] According to the invention, a laying tool for floor coverings, which can be connected to one another in particular using a tongue and groove connection, is proposed, comprising a support element, a guide element, and a bolt element. At least one guide groove for the guide element is provided in the support element, which extends along a longitudinal extent of the support element. The guide element is mounted in the at least one guide groove so that its position can be adjusted along the longitudinal extent of the support element. Furthermore, the bolt element can be guided in a recess extending parallel to the at least one guide groove. In addition, the bolt element is at least indirectly fixed to the guide element. A stop for the bolt element is arranged at a respective longitudinal free end of the support element.Furthermore, a projection for contact with a floor covering is formed on one of the stops, such that when the bolt element strikes at least one of the stops, an impulse of the bolt element can be transmitted at least partially to the stop with the projection, and thus indirectly to a floor covering resting against the projection.

[0009] The advantage of this is that, thanks to the bolt element being guided in the recess of the support element, which is designed in particular as a through-hole, the risk of injury to the user is reduced, as the moving or force-exerting parts are located inside the recess and are not freely accessible on the support element. Furthermore, no additional tools, such as a hammer, are required. Furthermore, due to the special design of the installation tool, it can be used with a tensile and / or compressive force acting on the corresponding floor covering. The projection of the stop is adapted in particular to a predetermined material thickness of the floor coverings to be installed.

[0010] In an advantageous embodiment, dampers made of an elastomer are arranged at each free end of the bolt element. It is advantageous that the stops made of an elastomer or rubber dampen the impact of the bolt element on the corresponding stop and thus also reduce noise generation.

[0011] The installation tool is preferably designed such that at least the stop with the projection, preferably both stops, are releasably fixed to the support element, in particular by means of at least one fastening means, preferably a screw, a pin, a bolt, and / or a locking element. In this way, the stops can be easily replaced, for example, to replace a worn stop. Furthermore, other components of the installation tool, such as the bolt element, can also be removed. This means that if a component becomes worn, the entire installation tool does not have to be replaced, thus increasing the durability of the installation tool.

[0012] In one embodiment of the invention, a set of stops is provided, each with a differently designed projection, wherein the extent and / or height of each projection is adapted to a predetermined material thickness of the floor covering to be installed. This is advantageous in that a differently designed stop can be used for a different material thickness of the floor covering to be installed, thus optimally adapting the installation tool to the floor covering to be installed.

[0013] Furthermore, a design is advantageous in which a handle is arranged on the guide element for the positionally variable, stepless displacement of the guide element. This improves the handling of the laying tool. For this purpose, a handle adapter is provided in particular, via which the handle is fixed to the guide element. In a further advantageous variant, the invention provides that the handle, in particular a gripping surface provided for a user, is arranged at an angle with respect to the longitudinal extent of the support element and / or the at least one guide groove. In this case, in particular the handle is designed to be correspondingly angled and / or the handle adapter is designed to be correspondingly stepped and / or ascending or descending. The angled arrangement of the handle, in particular, further optimises the transmission of force from a user via the handle to the bolt.

[0014] The laying tool according to the invention is designed in one embodiment such that the recess extends centrally and / or centrally through the support element, such that the bolt element can be guided centrally and / or centrally through the support element. It is advantageous that the internal weight or mass is precisely balanced with respect to the center of mass of the laying tool, thus improving its handling.

[0015] It is also advantageous if the support of the laying tool is designed like a strut profile.

[0016] In a further advantageous embodiment, it is provided that the support element is made of aluminum.

[0017] Preferably, the guide element of the laying tool is made of plastic.

[0018] In an alternative embodiment of the present installation tool, it is further provided that at least one contact surface of the stop for contact with the floor covering is made of plastic and / or an elastomer and / or has a coating of plastic and / or an elastomer. In this way, the corresponding floor covering is protected during the transmission of impulses or force from the installation tool to the floor covering, and the likelihood of damage to the floor covering is reduced.

[0019] In a preferred embodiment of the invention, a support plate is / are arranged on a support side of the laying tool for placing the laying tool on floor coverings, which support side is in particular opposite an upper side of the laying tool with the at least one guide groove, which support plate extends from one of the stops to the other of the stops, or two support plates, each extending from one of the stops with a predetermined longitudinal extent along the support side of the laying tool. In particular, it is conceivable for the corresponding support plate to be made of plastic and / or an elastomer and / or to have a coating made of plastic and / or an elastomer. The support plate ensures even pressure distribution on the floor covering during installation.The support plate also protects the floor covering, especially when dealing with delicate materials such as wood or laminate flooring. Furthermore, using a support plate improves the stability of the installation tool.

[0020] In a further embodiment, the bolt element is fixed to the guide element indirectly via a connecting element. Alternatively, a connecting projection is formed on the bolt element and / or the guide element. Furthermore, the bolt element, guide element, and / or connecting projection are fixed to one another, in particular releasably, by means of fastening means. The connecting element bridges a distance between the guide element and the bolt element and is designed such that the bolt element is arranged centrally and / or centrally in the recess.

[0021] Furthermore, an embodiment is advantageous in which a connecting recess extending parallel to the at least one guide groove is formed in the support element, via which the bolt element can be at least indirectly fixed and / or guided on the guide element.

[0022] In one embodiment of the invention, at least one further guide groove for the guide element is provided on a respective side surface of the support element, said groove extending along a longitudinal extent of the support element. The guide element is designed to engage around a corresponding side edge of the respective side surface. Furthermore, the guide element is mounted in the respective further guide groove so that its position can be adjusted along the longitudinal extent of the support element.

[0023] In a preferred embodiment of the invention, the respective guide groove is a T-slot, and the guide element has correspondingly complementary, particularly T-shaped, projections for engaging in the corresponding guide groove. The advantage of this is that appropriately designed grooves enable relatively easy assembly and disassembly of components, particularly the guide element, since they can be inserted laterally when the stop is removed. The T-shape facilitates the alignment of components and enables precise positioning and repeatability.

[0024] The features disclosed above can be combined as desired, as long as this is technically possible and they do not contradict each other.
