Description

The invention relates to a device for holding the outer flanks of a beginning or completion plank of a plank arrangement consisting of several parallel planks.

In a plank arrangement of the type mentioned above, it may be a podium, for example inform a terrace covering or a wall or ceiling paneling or the like.

A plank arrangement of the type mentioned is from the WO 2009/025564 known. In this known arrangement, the holding elements are provided with mutually facing, parallel contact surfaces which are formed as a wedge-like cooperating, rising from the outer edge of the respective Enddiele inwardly inclined, inclined planes, wherein the bearing side attached to the holding element associated contact surface fixed the contact surface of the dielenseitig Retaining element overlaps, so that a mutual horizontal movement leads to a downwardly directed, acting on the associated end platen contact force. In this known arrangement must For this purpose, the dielenseitig fixed holding element and, accordingly, the associated end plank are moved with a pointing towards the outer edge movement direction, which is well possible in the beginning plank of a plank arrangement, but not or only with great effort in a Abschlussdiele. In addition, in the known arrangement, the relative movement is limited by a stop of the holding element provided on the bearing side, which can lead to the inclined planes not achieving mutual press contact. On the other hand, for example, a fading of existing wooden planks or the like can cause the mutual contact surfaces can come out of contact, whereby the downwardly acting contact pressure and the frictional engagement of the mutual contact surfaces omitted, so that there may be a lot of the end plank in question. This known arrangement therefore proves to be not easy to install and reliable enough and therefore could not prevail in practice. A device according to the prior art for holding a plank arrangement is shown in FIG US3713264A
disclosed. Devices for holding the outer flanks of a beginning or end panel of wall or ceiling panels are also covered by the documents WO2009 / 025564A1 . EP0168097A1 . JP2007098073A . DE19852298A1 . DE19511538A1 . DE3046297A1 . DE3032343A1 and DE3203467A1 disclosed. In practice, the initial and final planks are still bolted through their respective outer edge area by cross-bolt with the underlying camps. Although such screws are quickly assembled and disassembled. The disadvantage, however, is that for the screws must be drilled through the wooden boards existing through holes. There is a risk that water can penetrate into the screw holes, which can adversely affect the life of existing wooden planks and / or existing wooden bearing. Another disadvantage is that the upper screw heads are visible, which is undesirable when used in the architectural field, for example in terrace coverings. In addition, as a result of the compression of the screw heads, the wood fibers break in the region of the head circumference, which leads to high fiber ends and also to a deterioration of the visual appearance. In addition, the screw heads and / or the upstanding fiber ends so-called trip hazards form, which can lead to a not inconsiderable risk of accidents. These measures also prove to be unsafe and reliable enough.

On this basis, it is therefore an object of the present invention to improve a device of the type mentioned with simple and inexpensive means so that can be dispensed with continuous screws and yet a simple structure and a simple and obvious assembly and a permanent hold the initial and finishing planks are guaranteed.

This object is achieved by a device according to claim 1, characterized in that the holding elements are formed as retractable, engageable in mutual positive locking engagement latching elements, wherein a holding element is provided with at least one toothing with a plurality of row-shaped successively arranged teeth and the each other holding element has at least one engageable with an associated toothing of the respective one holding element for engagement locking tooth, and wherein at least one of the holding elements has a suitable for a resilient deflection of the respective associated locking member design. As a result of the mutual, positive locking engagement, the respectively associated holding elements are reliably locked against each other, so that a so-mounted initial or final plank can neither be lifted from the camps or leave its mounting position relative to the adjacent planks. With the measures according to the invention, therefore, the disadvantages of the initially described arrangements and devices are completely avoided.

Advantageous embodiments and expedient developments of the higher-level measures are specified in the subclaims. Thus, a holding element may be provided with at least one toothing and the respective other holding element have at least one engageable with this toothing locking tooth, wherein each at least one of the holding elements has a suitable for a resilient deflection of the associated locking member construction. These measures advantageously allow a ratchet-like arrangement, wherein the two holding elements only in the the direction of retraction opposite direction of movement are blocked against each other, so that any desired locking position can be achieved.

Suitably, the teeth of a latching element may be profiled sawtooth, which advantageously favors the required lateral deflection during displacement of a holding element relative to the other holding element.

A particularly preferred embodiment of the parent measures may be that one of the holding elements is based on a cross-sectionally C-shaped pocket which is open at the opposite side of its support surface and flange flanges flanking the opening, of which at least one, preferably both, provided on the edge with a toothing or is designed as a ratchet tooth or are. The lateral legs of the cross-sectionally C-shaped, open-top pocket advantageously form lateral spring legs which favors the mentioned ratchet effect and enables the mutual mobility of the latching elements. This applies regardless of whether the flange strips are provided with a toothing or as a ratchet tooth. The respective other holding element can be designed as a longitudinally of the opening in this retractable ratchet carrier with at least one lateral ratchet tooth or as a perpendicular to the opening retractable tooth carrier with at least one toothing. The ratchet tooth or the teeth can be formed stiff due to the resilient property of the cross-sectionally C-shaped pocket without own spring property.

In further development of the above-mentioned measures designed as a ratchet support member may have a T-shaped locking head, the crosspiece is longer than the mutual distance of the intervening thereof undercut, provided with toothed flange strips and its projecting from a support base neck on at least one, preferably on both flanks forms a locking tooth. The coming into meshing engagement with the teeth of the flange of the other support member neck secures the desired position against the direction of displacement. The crossbar prevents the relevant holding element can be lifted.

In a further development of the higher-level measures, the bearing side fixable retaining element may be provided on its upper side with projecting center points, which are preferably arranged according to a hole pattern of mounting holes of the respective dielenseitig fixable retaining element. These measures allow a simple and accurate installation despite the use of two retaining elements.

Further advantageous embodiments and expedient developments of the parent measures are specified in the remaining subclaims and from the following description of the example with reference to the drawing closer.

That the FIG. 1 underlying podium, for example in the form of a terrace covering etc. consists of several parallel, designed as wooden floor boards planks 1a, 1b, which are on transverse thereto, formed by squared timbers etc. bearings 2 can be accommodated. The first and the last hall, ie the outer planks 1a, form a Anfangsdiele or Abschlussdiele. In between are the inner planks 1b, of which in FIG. 1 only one is shown. The planks 1a, 1b, are connected in the region of their longitudinal sides by suitable holding devices with the bearings 2, wherein the mutually facing longitudinal sides of adjacent planks 1a, b, common, inner holding means 3 and the outer longitudinal sides of the outer planks 1a different from the holding means 3 Endhalteeinrichtungen 4 are assigned.

The planks 1a, b, are provided in the region of their longitudinal sides facing each other with lateral edge grooves 5 facing one another. Accordingly, the inner planks 1b are provided with an edge groove 5 on both sides. The outer planks 1a are in any case provided with an edge groove 5 in the region of their longitudinal side facing an adjacent inner plank 1b. In the region of the opposite longitudinal side, such an edge groove may also be provided, but does not have to, as FIG. 1 lets recognize.

The inner holding devices 3 each have, as FIG. 1 clearly shows, for engagement in mutually facing Randnuten 5 adjacent planks 1a, b, bringable clamping plate 6, a this penetrating, screwed into an associated bearing 2 screw 7 and a first, accessed by the screw 7, the bearing distance of the clamping plate 6 and / or the mutual lateral distance of each adjacent boards 1 a, 1 b defining spacers 8 and a second, the bearing distance of the adjacent boards 1 a, b, defining spacers 9, wherein the difference between the defined by the first spacer 8 and the second spacer 9 bearing distances is slightly smaller than the thickness of the lower, the side-side groove 5 flanking leg 10 of the planks 1a and 1b. In this way it is possible that the clamping plate 6 can exert a clamping action, whereby the associated planks 1a, 1b, are pressed onto the lower spacer 9, so that there is a clamping. Suitably, the lower spacers 9 each have at least one extending transversely to the plank longitudinal web 11, which in consequence of said pressure in the bottom of the wooden existing planks 1a, b, penetrate and thus can secure against unwanted displacement in plank longitudinal direction.

The end retainers 4 are as shown FIG. 1 right vividly apparent, formed in two parts and accordingly have two mutually releasable retaining engagement engageable, facing each other holding elements 4a, b, of which one, here the upper support member 4a on the plank base and the other, here the lower support member 4b bearing side can be fixed.

The two-part end holder 4 is designed as a latching device with two latching elements which can be positively locked with one another and are assigned to the holding elements 4a, 4b. This can, like the Figures 1 and 2 schematically show a first support member a toothing 12 here in the form of a rack with row-shaped successively arranged, separated by tooth notches teeth and a second holding element hereby engageable with a locking tooth 13. The two locking elements are generally suitably designed and arranged so that the ratchet 13 can lock the associated teeth 12 only in one direction of movement and allows movement in the other direction. The ratchet 13 is connected to an example in accordance with FIGS. 1, 2 mounted on the upper side bearing support frame 14 and forms with this the bearing side fixable holding member 4b, while the teeth 12, here attached to a fixable on the underside of an associated plank 1a holder 15 and forms with this the other dielestitig fixable holding member 4a.

The locking tooth 13 extends in the example according to FIGS. 2 and 3 in a direction away from the outer edge of the associated start or Abschlussdiele 1a direction obliquely upward. The ratchet 13 may have a certain width, which extends in the longitudinal direction of the plank. The toothing 12 has a plurality of teeth 16, which are arranged one behind the other and are separated by tooth notches, which are generally preferably sawtooth-shaped in profile and, accordingly, have a tooth which is offset from the outer edge of the associated tooth. or end plank 1a facing away, have sloping back, so that it is possible that the holder 15 with its teeth 12 in the in FIG. 3 indicated by an arrow 17 direction from the outside into the ratchet 13 containing support frame 14 is retractable. The ratchet 13 has so much elastic resilience that he can pass over the teeth 16 of the teeth 12. Since the toothing 12 has a plurality of teeth 16 arranged one behind the other, an exact positioning of the associated plank 1a in steps corresponding to the tooth spacing is possible. The teeth 16 of the teeth 12 are parallel to the ratchet 13 and suitably have the same extent in plank longitudinal direction.

The the ratchet 13 associated carrier frame 14 of the arrangement according to FIGS. 2 and 3 is like FIG. 4 below illustrates, designed in the manner of a portal, which has a base plate 18 from which the ratchet 13 projects obliquely upward, and two the centrally arranged ratchet 13 flanking, in cross-section approximately gallows-shaped side parts 19, the upwardly facing, successive striving, however possess with mutual spacing ending, tab-shaped legs 20. The toothing 12 associated holder 15 has, as FIG. 4 shows at the top a toothing 12 bearing tongue 21, which is flanked by lateral support strips 22. Suitably, the tongue 21 may be cut out of a web and bent out, form the lateral end portions of the support strips 22.

The toothing 12 is, as already mentioned above, starting from the situation according to FIG. 3 inserted into the support frame 14 and thus in the position according to FIG. 2 brought, with the upper legs 20 of the side parts 19 of the support frame 14, as best of FIG. 2 it can be seen, are under attack by the toothing 12, which is supported with its upper side on the underside of the legs 20 and wherein the support strips 22 of the holder 15 rest with its underside on the upper side of the legs 20 and are supported thereby. The width of the tongue 21 corresponds at most to the distance between the upper legs 20, between which they pass through with preference without play. The teeth 12 containing Tooth bar protrudes laterally beyond the tongue 21, so that the above-mentioned support on the legs 20 of the side parts 19 of the support frame 14 results.

The measures mentioned give a reliable floor support down and up while ensuring a reliable meshing. Since the only in the arrow 17 in FIG. 3 opposing direction locking ratchet 13 with a movement of the teeth 12 in the direction of arrow 17 due to its elasticity on the sawtooth profiled teeth 16 of the teeth 12 can snatch away, results in a ratchet-like arrangement, which makes it possible to engage the ratchet 12 in each notch and so with each desired tooth 16 of the teeth 12 into engagement, or to push them all over the ratchet 13 away and so disengage. To the above the ratchet 13 pushed away toothing 12 and with this the associated plank 1a to lift upwards, the upper legs 20 of the side parts 19 of the support frame 14 are accordingly excluded, so that in FIG. 4 indicated niches 23 result, over which the toothing 12 containing toothed rack can be moved upwards out of the support frame 14.

In another advantageous embodiment of a locking device designed as a stop means, a latching element may be associated with a cross-sectionally C-shaped pocket. In which the FIG. 5 The underlying example is an at least one ratchet-containing and with this a holding element, here the dielenseitig settable holding member 4b forming support frame 14a, such as FIG. 5 below shows, as formed in cross-section C-shaped pocket, which is arranged with the opening facing upwards. The lateral, here parallel-extending, laterally elastically deflectable legs of this bag have upwardly facing, successive aspirated flange strips 24 which are provided with V-shaped mutually inclined, each having a ratchet 13a forming Randabwinklungen. In this case, two spaced apart, parallel ratchet teeth 13a, which extend in the longitudinal direction of the carrier frame 14a forming pocket, accordingly result.

One of a toothing associated and with this the other holding element 4a forming holder 15a is, as seen from FIG. 5 can be seen above, to form the teeth 12a provided with a along its central longitudinal plane extending downwardly projecting web, which is provided on both sides with a plurality of successively arranged in cross-section saw teeth 16a. To the the FIG. 5 To bring the underlying latching device in the working position, the holder 15a is pressed with the here-toothed web from above between the ratchet teeth 13a, each side of the here on both sides toothed web comes with an associated locking tooth 13a for engagement. At the same time, a support of the holder 15a can be made on the flange strips 24 of the support frame 14a acting as receiving strips. In order to bring the two locking elements in this embodiment except mutual engagement, the holder 15a is simply pushed out of the support frame 14a in the longitudinal direction of the ratchet teeth 13a and the rack 12a. The support frame 14a and the holder 15a are accordingly suitably mounted on the associated bearing 2 and the associated initial or Abschlussdiele 1a, that the ratchet teeth 13a and the rack 12a extend in the plank longitudinal direction, so that a disassembly by appropriate movement of associated plank 1a in plank longitudinal direction is possible.

The carrier frame 14 or 14a and the holder 15 or 15a are suitably screwed to the associated bearing 2 or the associated beginning or end plank 1a, wherein, as in FIG. 2 is indicated, non-continuous wood screws 25 find use. The support frame 14 or 14a and the holder 15 or 15a are for this purpose provided with suitable fastening tabs 26 and 27, each having at least one bore 28 for an associated screw. Suitably, the support frame 14 or 14a is first attached to an associated bearing 2. In order subsequently to allow an exact positioning of the associated holder 15 or 15a, the support frame 14, 14a, as shown in FIGS FIGS. 4 and 5 it can be seen, on its upper side with at least one upwardly projecting center point 29, expediently more Such body tips 29 may be provided, which are arranged according to the hole pattern of the holes 28 of the holder-side fastening tabs 27. With the help of the center points 29, the location for the attachment tabs 27 associated, the side-mounted attachable screws 25 is accordingly marked.

The FIG. 6 contains an alternative to FIG. 5 , To avoid repetition, the differences are highlighted below.

Also in the execution according to FIG. 6 is provided in cross-section C-shaped pocket, as in the embodiment according to FIG. 5 an organ is assigned to a latching device. In the execution according to FIG. 6 is a at least one toothing 12a 'and with this the associated holding member 4b forming holder 15a' formed as a cross-sectionally C-shaped pocket, which is here to attach to a bearing 2. The holder 15a 'forming in cross-section C-shaped pocket is open at the opposite side of its support surface and as in Fig. 5 provided with the opening flanking flange strips 24, of which at least one, in the example shown, both edges with a toothing 12a 'are provided. The gearing 12a 'containing edge racks of flange strips 24 or the entire flange 24 may be V-shaped inclined to each other, but it must, in contrast to Fig. 5 Not.

A support frame 14a 'which contains at least one ratchet tooth 13a' and forms with it the further retaining element 4aa which can be fixed on the side, is designed according to the embodiment FIG. 6 formed as a support plate from which a T-shaped locking head 30 protrudes, the transverse web 31 extends parallel to the plate and the neck 32 on at least one side, preferably on both sides, a locking tooth 13a 'forms. The locking head 30 is formed as provided with lateral cut-edge angle of the support frame 14a 'forming support plate. The holding element 4b containing them can therefore be like the one in cross section C-shaped bag can be produced as a punching and bending molding. The length of the transverse web 31 of the locking head 30 is greater than the distance of the teeth 12 a 'of the edge-toothed flange strips 24 in FIG. 6 the retaining element 4b underlying, in cross-section C-shaped pocket.

When retracting the retaining element 4a in the retaining element 4b, the flange strips 24 are traversed by the cross bar 31, which results in a reliable safeguard against lifting. The neck 32 of the latching head 30 thereby passes into the opening between the flange strips 24. In order to facilitate the insertion process, the flange strips 24 are here provided on the insertion side with converging bevels 33 in the retraction direction. The locking teeth 13a 'formed by the lateral flanks of the neck 32 of the locking head 32 snap in the course of the advancing movement in the notches between the teeth of the teeth 12a', wherein here again the C-shaped cross-sectional contour of here the holder 15a 'underlying pocket the required laterally resilient property results to allow the detent.

In the execution according to FIG. 6 should, as in the execution according to FIG. 5 , Also, the containing the cross-sectionally C-shaped pocket holding member 4b, are determined on the storage side. In contrast to Fig. 5 Here, the arrangement is such that the flanked by the teeth 12a 'opening extends transversely to the plank longitudinal direction. The arrangement according to Figure 6 therefore combines the advantages of the other two variants 4 and FIG. 5 in itself.

With respect to the fastening flanges provided with mounting flanges and the equipment of the upper flange strips 24 'of the C-shaped bag with upwardly projecting center points 29 whose arrangement corresponds to the hole pattern of the mounting holes 28 of the opposite holding element 4a underlying support plate, the same applies as in Fig. 5 ,

Although some embodiments of the invention are explained in more detail above, without this, however, a restriction should be connected. Rather, stand the skilled person a number of ways available to adapt the present invention to the circumstances of the case. For example, it would also be possible, in place of the locking teeth shown with rack 12 and locking tooth 13, other types of releasable form-fitting latching engagement, z. B. a locking in the form of a push button assembly, etc. to provide.
