Description

field of technology

[0001] The invention relates to a table top with a table base, wherein the table base is detachably connected to the table top.

[0002] The invention further relates to a locking element for the releasable connection of a table base to a table top. State of the art

[0003] Tabletops of the type in question are known, for example, for use in motorhomes and caravans. Especially in this area of application, an easy-to-assemble, lightweight, yet stable design is preferred.

[0004] For example, such a table top is known from DE 10 2015 102 660 A1. A detachable connection between a table top and a table base is also known, for example, from US 1 885 635 A. Summary of the invention

[0005] In view of the above-described prior art, one object of the invention is to provide an improved design of a table top and a locking element of the type in question.

[0006] A possible solution to the problem is provided according to a first inventive idea in a table top in which the table top has a recess with a recess edge on the underside, that the recess has an extension area beyond the recess edge and that a locking element attached to the table base engages in the extension area for releasably holding the table base on the table top.

[0007] With regard to the locking element, according to a further inventive concept, the locking element is designed to engage in a recess on the underside of the table top.

[0008] Thanks to the proposed snap-in fastening, the table leg can be secured to the table top in a convenient manner. Preferably, no further fastening measures, such as screwing or the like, are required. In a preferred embodiment, the table leg's securing position on the table top can be achieved without tools, as can, further preferably, the securing position upon disengagement of the locking mechanism.

[0009] The locking mechanism occurs between the locking element provided directly or indirectly on the table base and the recess formed in the area of the table top's underside. The sections that actively assume the locking position are formed accordingly on the table base. The table top, however, can be provided with only the aforementioned recess to enable the locking mechanism, thus facilitating production.

[0010] The recess may appear stepped in a cross-section transverse to the insertion direction of the locking element into the recess, with a through-hole region, viewed perpendicular to the insertion direction, associated with the recess edge, and an extended region following in the insertion direction, which is wider than the through-hole region transverse to the insertion direction. This results in a rear engagement region at the transition from the extended region to the region of the recess edge, which is engaged behind by a portion of the locking element in the latching position.

[0011] Further features of the invention are explained below, also in the description of the figures, often in their preferred association with the subject matter of claim 1 and / or claim 2 or with features of further claims. However, they may also be important in association with only individual features of claim 1 and / or claim 2 or of the respective further claim, or each may be important independently.

[0012] Thus, in one possible embodiment, the locking element can have one or more locking tongues, which, with an overlapping portion, overlap the recess edge in the locked state. The overlapping portion can have a locking surface that, in the locked state, engages against a facing support surface of the preferably stepped recess. The locking surface and the support surface of the recess can, as is also preferred, run essentially parallel to one another.

[0013] In a further embodiment, the locking element can comprise a spring element which, in the locked state, clamps the locking tongue against the tabletop, and in particular the overlapping portion against the facing support surface of the recess. The spring element is preferably tensioned when the locking position is assumed, whereby this spring tension can only be released again when the locking position is released.

[0014] The spring element can be formed integrally with the locking element, in particular with its locking tongue, and optionally also made of the same material. The locking element can, for example, be a plastic injection-molded part.

[0015] The locking element can also have a contact projection that, in the locked state, rests against the tabletop from the outside. Thus, in the locked state, the edge of the recess and thus the stepped area of the recess containing the support surface can be gripped between the contact projection on the outside and the overlapping section on the inside of the support surface.

[0016] In a further embodiment, the spring element can be formed on the contact projection. The contact projection can form a rigid base for the spring element. For example, the spring element can be formed by a dome-like shape of an edge portion of the contact projection.

[0017] In one possible embodiment, the locking tongue can be movable essentially transversely to the surface of the tabletop to engage or release the locking position. This allows the locking tongue to deflect transversely to the insertion direction, particularly during insertion displacement, but also during the release of the locking. For this purpose, the locking tongue can further be provided with a control bevel, via which automatic deflection transversely to the surface of the tabletop can be achieved, particularly during the insertion process.

[0018] In this context, it is further preferred that the locking tongue be spring-biased into the locking position. Accordingly, particularly during the insertion movement of the locking element, a buildup of spring force results, which, once the recess edge has been overrun, causes the automatic return of the overlapping section, in particular, into the overlapping position. For this purpose, a separate spring part acting on the locking tongue can be provided. In this regard, a tongue section of the locking tongue itself supporting the overlapping section is preferably designed as a spring part through an appropriate configuration and / or through a favorable choice of material.

[0019] The locking element can also have a rigid engagement projection that engages into the recess when locked. The engagement projection can provide essentially radial support for the table top via the edge of the recess on the locking element on the table leg side. The engagement projection can significantly contribute to stabilizing the table top / table leg connection.

[0020] The engagement projection can be rigidly connected to the contact projection or a partial section of the contact projection, if necessary in one piece with it and further if necessary made of the same material.

[0021] Two opposing engagement projections may be provided, separated from each other by one or both locking tongues. Thus, engagement projections and locking tongues may be provided alternately in a circumferential direction of the locking element—relative to a body axis of the locking element oriented in the insertion direction—wherein the engagement projections and the locking tongues may each be substantially identical and diametrically opposite.

[0022] According to a possible refinement, two or more locking elements can be provided for securing the tabletop, which can be connected to a single table leg. For example, four locking elements can be mounted on one table leg, which engage with an equal number of recesses (in this example, four recesses) on the underside of the tabletop. This can result in, for example, four-point support for the tabletop on the table leg, which may be centrally positioned.

[0023] Two locking elements can be connected by a connecting element extending parallel to the surface of the tabletop on the underside. Such a connecting element can also be designed to hold the tabletop horizontally displaceable in one or more directions relative to the table base in its orientation of use. The table base can be attached to the connecting element, optionally displaceable and / or tiltable relative to it.

[0024] The locking element can have a first opening for receiving one end of a connecting element or a table base. The free end of the connecting element or table base can be inserted into this first opening. In a preferred embodiment, the free end of the connecting element sits in this first opening without further fixation, for example, by means of a screw connection or the like. This results in a plug-in holder that is easy to install.

[0025] In a preferred embodiment, this first opening is directed transversely to the insertion direction of the locking element into the recess on the tabletop. In the normal use state of the tabletop, the first opening preferably has a substantially horizontal orientation.

[0026] According to a further development, the locking tongues and, if applicable, the engagement projections can delimit a second opening of the locking element. The locking tongues or their tongue sections form resiliently movable sections of the opening wall of the second opening, while the engagement projections form fixed sections of the wall. To increase stability, these fixed wall sections can be connected to one another by a support web, for example, running along a diameter line.

[0027] Particularly when using multiple connecting elements, the first opening and the second opening can be oriented substantially at right angles to each other. If, as described above, the first opening is oriented substantially horizontally in a normal use position of the table top, the second opening preferably points vertically upward.

[0028] In a further development of the subject matter of the invention, a locking part can be provided which prevents the locking tongues from moving in the locking position to release the locking position. The locking part can, as preferred, be inserted into the locking element after the locking tongues have assumed the locking position to secure this locking position. The locking part can also be mounted on the locking element and, for example, be linearly displaceable from a non-locking position to the locking position to secure the locking position.

[0029] For example, the locking part can also be present as a loose part and can be inserted into the second opening of the locking element, more preferably in the insertion direction of the locking element into the table-side recess.

[0030] The locking tongues are supported by the locking part, which is moved into the locking position, in such a way that they cannot be displaced in the direction of deflection that would cancel the locking position. Furthermore, the locking part can even further load the locking tongues with their overlapping sections toward the locking position.

[0031] The locking part can be plate-shaped, with two broad surfaces extending essentially parallel to each other, which define narrow edges of the locking part extending in the insertion direction. These narrow edges of the locking part can prevent the locking tongues from deflecting to release the locking position.

[0032] In the position locking the locking tongues, the locking part can be held in the locking element in such a way that the locking position thus created can only be released intentionally, possibly only with the aid of a tool. Thus, the locking part can be held on or in the locking element, for example, with a force-locking or form-locking action, or furthermore, for example, with a frictional engagement or by forming a latching connection.

[0033] The tabletop can have a layered structure with several layer elements that are connected to one another, for example, by adhesive bonding. The lower layer element, which preferably interacts directly with the locking element, consists of a solid material, such as wood, metal, or plastic, in particular hard plastic. The lower layer element can also be formed, for example, as a plywood panel, thin fiberboard or chipboard, aluminum panel, or even as a high-pressure laminate. In any case, the choice of material for forming the lower layer element ensures that forces introduced via the tabletop can be safely absorbed and transferred to the table base via the locking elements.

[0034] The second layer element can be made of a lightweight material, for example a foamed plastic or a plant-based material, such as a material based on expanded corn (so-called popcorn plate), which provides structure and stability and stabilizes the dimensions, in particular to reduce the weight of the table top as a whole.

Description of the embodiments

[0036] Shown and described is, firstly, with reference to Fig. 1, a locking element 1 for the detachable connection of a table base 2 with a table top 3, as shown by way of example in the Fig. 16 and Fig. 17. The Fig. 1 to 17 a first embodiment of the locking element 1 and the further Fig. 18 to 28 a second embodiment.

[0037] The locking element 1 can, as is also preferred, be manufactured as a plastic injection-molded part, with a locking section 4 designed for locking interaction with the table top 3 and a receiving section 5 aligned substantially at right angles thereto for a partial section of the table base 2.

[0038] The fastening of the support bracket-like locking element 1 can be provided directly on the table base 2 designed for support on a floor 14, for example, the floor of a caravan. Alternatively, as also preferred and shown in the drawings, the locking element 1 is arranged at the end of a tubular connecting element 6 connected to the table base 2.

[0039] The connecting element 6 can be part of a tabletop support 7, which can essentially consist of a central bridge part 8 and several support tubes guided in tubular profiles. For example, support tubes 10 are mounted in two parallel profile tubes 9, capable of sliding displacement in their longitudinal direction. Transverse profile tubes 11, which extend transversely to the ends of these support tubes 10, are in turn attached to the ends of these support tubes 10, in which the aforementioned connecting elements 8 are guided as transverse support tubes, also capable of sliding displacement transversely to the previously described displacement direction.

[0040] The table top holder 7 thus formed, in particular each connecting element 7, extends on the underside of the table top 3 essentially in a parallel alignment to the surface extension of the table top 3.

[0041] The locking elements 1 are arranged at the ends of the connecting elements 7. The corresponding free end 13 of a connecting element 7 engages into a first opening 12 of the locking element 1 in the region of its receiving section 5. Four locking elements 1 are provided associated with the table top 3, corresponding to the number of free connecting element ends 13.

[0042] The table leg 2 is attached to the bridge part 8, for example by means of a screw connection, so that it can be arranged centrally on the tabletop surface, as preferred. Furthermore, the central table leg 2 can be fixed to the floor 14, for example also by means of a screw connection. A slidingly displaceable mount on the floor 14 is also possible in this regard.

[0043] Furthermore, the column-like table base 2 can be rotatable together with the table top 3 about its column axis x, which is vertically oriented in the usual use position. After releasing a lock, the table top 3 can also be pivoted about a pivot axis y, which is essentially horizontally oriented in the usual use position, from the usual horizontal use position into a vertical non-use position.

[0044] The receiving section 5 for the end 13 of the connecting element 6 has a wall 15 that completely and tightly surrounds the first opening 12, with a base section 18, a top section 19, and two opposing side wall sections 20. The opening cross-section is preferably designed to match the outer cross-sectional contour of the connecting element 6, in particular its end 13. In the illustrated embodiment, this results in a substantially rectangular cross-section.

[0045] Furthermore, an insertion direction S1 of the free end 13 into the first opening 12 results, which insertion direction S1 results in the usual use position of the table top 3 corresponding to the table top surface essentially in the horizontal direction.

[0046] The locking section 4, which is formed opposite the opening surface of the first opening 12 in the insertion direction S1, has a substantially pot-shaped design, with a pot base 16 in the region of the lower end of the locking section 4 in the usual use position of the table top 3, which pot base 16 is surrounded by a pot wall 17. The pot wall 17 encloses a second opening 21 of the locking element 1, which second opening 21 is directed substantially at right angles to the orientation of the first opening 12 in a vertical section through the locking element 1 - based on the usual use position of the table top 3.

[0047] In a preferred embodiment, an outer surface of the associated base section 18 of the receiving section wall 15 merges substantially flush with the outer surface of the pot base 17 (cf. Fig. 2).

[0048] While the first opening 12 has a substantially rectangular opening cross-section adapted to the cross-section of the connecting element 6, the pot wall 17 of the locking section 4 defines a second opening 21 with a preferably circular cross-section (compare Fig. 1).

[0049] In the illustrated embodiment, two locking tongues 22 are formed diametrically opposite one another with respect to a pot axis z in the pot wall 17. For this purpose, slots 23 extending in the direction of the pot axis z are formed in the pot wall 17 on both sides of a locking tongue 22 in the circumferential direction. One end of the slots opens into the circumferential wall edge 24 and ends opposite one another at a distance from the pot base 16.

[0050] The locking tongues 22 can, as shown, be arranged associated with the side wall sections 20 of the receiving section 5 and each have a tongue section 25 which, in the region of its end associated with the wall edge 24, carries an outwardly directed overlapping section 26.

[0051] The tongue section 25 rooted in the region of the pot bottom 16 in the pot wall 17 provides springability of the locking tongue 22 in the radial direction - with reference to the pot axis z.

[0052] The overlapping section 26 is wedge-shaped, based on a longitudinal section through the locking section 4, in which longitudinal section the pot axis z is represented as a line, with a control surface 27 extending from the wall edge 24 and rising radially outwards and a locking surface 28 adjoining the radially outer end of the control surface 27 and extending radially inwards in an unloaded state of the locking tongue 22.

[0053] Viewed in the circumferential direction of the cup wall 17, engagement projections 29 remain between the two locking tongues 22 formed by the cup wall 17 and correspondingly arranged diametrically opposite one another. These engagement projections 29 are connected to one another via a support web 30 extending along a diameter line through the second opening 21, resulting in an overall rigid design of the two engagement projections 29. The support web 30 preferably merges integrally into an engagement projection 29 approximately centrally along the circumferential extent of the latter, with the support web 30 further extending approximately in the direction of the first insertion direction S1.

[0054] The pot wall 17 is surrounded by a collar-like contact projection 31 which projects essentially radially outwards from the pot wall 17 and which, viewed in the circumferential direction, is interrupted by the slots 23, so that first partial sections 32 of the contact projection 31 are formed on the outside at the tongue sections 25 of the locking tongues 22 and second partial sections 33 are formed on the outside at the rigid engagement projections 29.

[0055] The contact projection 31 is arranged at an axial distance below the transverse plane defined by the locking surface 27 of the overlapping section 26, wherein, facing the locking surface 27, the first partial section 32 of the contact projection 31 forms a counter-locking surface 34 which, in the normal state of use, runs parallel to the locking surface 27. The contact projection 31 projects radially beyond the overlapping sections 26, wherein the first partial section 32, following the counter-locking surface 34, merges into a sloping inclined surface 35 which becomes increasingly spaced radially outwards from the transverse plane defined by the counter-locking surface 34.

[0056] The lower surfaces 36 of the partial sections of the contact projection 31 facing away from the overlapping sections 26 extend - with reference to the usual use position - in a plane perpendicular to the pot axis z and more preferably parallel to the blocking surface 28 and / or the counter-blocking surface 34.

[0057] In the region of the second subsection 33 of the contact projection 31, a spring element 37 is formed, associated with each rigid engagement projection 29. The spring element 37 is preferably provided approximately centrally of the second subsection 33, viewed in the circumferential direction, associated with the outer edge. As preferred, this can be a spring arch formed integrally and more preferably of the same material as the contact projection 31, projecting beyond the plane of the counter-blocking surface 34.

[0058] The locking element 1 is designed for locking interaction with a recess 38 formed on the underside of the table top 3. Depending on the number and positioning of the locking elements 1, a plurality of recesses 38, preferably of the same design, are also provided.

[0059] Each recess 38 is initially provided in the form of a bore, having a circumferential recess edge 39.

[0060] Beyond this recess edge 39, the recess 39 has an extension area 40 between the tabletop lower surface 43, into which the recess 38 opens with the recess edge 39, and the tabletop surface 44, which is unaffected by the formation of the recess 39 and forms the usable area in the normal use position. This extension area 40 can have a circular cross-section, similar to the recess area directly delimited by the recess edge 39, but with a larger diameter.

[0061] The diameter d in the widened region 40 can correspond to approximately 1.3 to 1.7 times, furthermore approximately 1.5 times, the diameter d' in the mouth region delimited by the recess edge 39. The diameter d' in the region of the recess edge 39 is adapted to the outer diameter d'' of the locking section 4 in the region of its cup wall 17.

[0062] The thickness e in the area of the recess edge 39, viewed in the thickness direction R, transversely to the surface extension of the table top 3, is selected to match the axial distance e' between the locking surface 28 and the counter-locking surface 34 on the underside of the overlapping sections 26 of the locking element 1. The height f of the extension area 40, viewed in the thickness direction R, also corresponds at least to the height f' of the overlapping section 26, viewed in the axial direction (cf. Fig. 11).

[0063] The above-described recess 38, which is essentially step-like in cross-section, can be achieved by first drilling a hole from the underside of the table top, with a depth which is composed of the thickness e and the height f, after which the extension area 40 is cleared out by means of a milling cutter above the plane defined by the thickness e of the edge 39 of the recess to be formed.

[0064] Alternatively, as also further preferred, the table top 3 has a layered structure with at least two layer elements, more preferably a lower layer element 41 and an upper layer element 42.

[0065] The lower layer element 41 is preferably made of a solid material, for example wood, metal or a hard plastic, and can have a thickness e adapted to the distance e' of the locking tongue 22, so that by forming a bore with a diameter d' the recess edge 39 can be created directly in the desired dimensions (cf. Fig. 10).

[0066] The upper layer element 42 can be made of a lightweight material, such as a foamed plastic or a plant-based material, particularly to reduce the weight of the table top 3. A popcorn-based upper layer element 42 is also possible, for example.

[0067] To form the extension area 40, a hole with the extended diameter d and a hole depth corresponding to the desired height f is made starting from the element surface to be connected to the lower layer element 41.

[0068] The layer elements 41 and 42 are then joined together to form a unit, for example by adhesive bonding.

[0069] To connect the table top 3 to the table base 2, the table base 2 is first provided with the locking elements 1 (four in the illustrated embodiment) indirectly via the connecting elements 6 of the table top holder 7, by sliding the locking elements 1 with their receiving sections 5 onto the free ends 13 of the connecting elements 6. Any further fastening of the locking elements 1 to the connecting elements 6 is preferably not provided.

[0070] Expediently, with the table base 2 and its table top holder 7 in the usual alignment, the table top 3 is placed on the table base 2 by inserting the locking sections 4 of the locking elements 1 into the table top-side recesses 38. This results in an insertion direction S2 of the locking sections 4, which insertion direction S2 is directed essentially perpendicular to the insertion direction S1 when inserting the connecting element 6 into the receiving section 5 - and vertically with respect to the usual usage position.

[0071] The Fig. 10 to 15 show the insertion process, during which the control surfaces 27 of the overlapping sections 26 initially come into contact with the recess edge 39 and, as a result of the movement of the locking element 1 in the insertion direction S2 relative to the table top 3, are directed radially inwards against the restoring spring force building up in the region of the tongue sections 25 of the locking tongues 22 (compare Fig. 12).

[0072] With continued movement of the locking element 1 in the insertion direction S2 (or with continued lowering of the table top 3 in the direction of the table base 3), the overlapping sections 26 overrun the recess edge 39, so that finally the overlapping sections 39 pivot radially outwards towards their relaxed basic position due to the restoring spring force of the tongue sections 25 and engage with their locking surfaces 28 over the recess edge 39 (compare Fig. 13). The locking surfaces 28 may rest against the facing, edge-side support surface 45 of the recess 38.

[0073] The recess edge 39 is then gripped between the locking surfaces 28 of the overlapping sections 26 and the counter-locking surfaces 34 of the contact projection 31. The spring elements 37 formed on the contact projection 31 act in this fastening position on the underside against the facing lower surface 43 of the table top 3 and thus clamp the overlapping sections 26 of the locking tongues 22 against the table top 3, in particular against the facing support surface 45 of the recess edge 39 (cf. Fig. 15). The wall sections of the engagement projections 29 engage in the recess 38 through the area of the recess edge 39 in a stabilizing manner.

[0074] A connection between the table base 2 and the table top 3 is created which is easy to assemble and can be made without tools simply by plugging and locking.

[0075] By shifting the tongue sections 25 radially inwards (see arrows P in Fig. 14) it is also possible to release the locking mechanism without tools, for example to change the table top, whereby as a result of such a load the overlapping sections 26 are moved against the return spring force of the tongue sections 25 into a pivoted position according to the position in Fig. 12, in which the locking element 1 can be moved outwards through the area of the recess edge 39.

[0076] In the Fig. In the second embodiment shown in Figures 18 to 28, a separate locking part 46 is provided to secure the locking position of the locking tongues 22.

[0077] In the illustrated embodiment, the locking part 46 can be present as a loose part and is preferably designed in a plate-like manner, with two broad surfaces 47, 48 running essentially parallel to one another, which delimit narrow edges 49, 50 running in the insertion direction of the locking part 46, which insertion direction can correspond overall to the insertion direction S2 of the locking element 1 into the recess 38.

[0078] In the area of the pot base 16, the locking element 1 has a slotted opening 51 adapted to a cross-sectional area of the locking part 46 transverse to the insertion direction S2. This slotted opening runs perpendicular to the support web 30 crossing the second opening 21.

[0079] After taking the rest position, for example according to the Fig. 26 and Fig. 27, this locking position can be secured by the locking part 46. For this purpose, the locking part 46, if present as a loose part, can be inserted through the slotted opening 51 into the second opening 21 of the locking element 1 in the insertion direction S2.

[0080] During the insertion process, the support web 30 of the locking element 1 is received in a slot 52 of the locking part 46 which is open at the front edge in the insertion direction S2.

[0081] The narrow edges 49 and 50 are in the insertion position according to Fig. 27 on the inner surfaces of the locking tongues 22 facing each other or extend at a maximum distance from the inner surfaces viewed transversely to the insertion direction S2, which distance does not allow the locking to be released.

[0082] The locking part 46 can extend with its narrow edges 49 and 50 from the pot bottom 16, for example, to the area of the tongue sections 25 carrying the overlapping sections 26 of the more preferably diametrically oppositely arranged locking tongues 22.

[0083] The locking tongues 22 are supported by the locking part 46, which is moved into the secured position, in such a way that they cannot be displaced in the deflection direction to cancel the locking position. Furthermore, the locking part 46 can possibly even further load the locking tongues 22 with their overlapping sections 26 in the direction of the locking position.

[0084] In the position securing the locking tongues 22, the locking part 46 can be held in the locking element 1 in such a way that the locking position thus created can only be released intentionally, possibly only with the aid of a tool. Thus, the locking part 46 can be held on or in the locking element 1, for example, in a force-locking or form-locking manner, furthermore, for example, in a frictional engagement or by forming a latching connection.

[0085] As shown, for example, as can be seen from the enlargements of the Fig. 25 and Fig. 26, point-like or dome-like elevations 55 can be provided on the wide surface side of the locking part 46, which in the securing position interact force-fittingly with the facing surfaces of the slot opening 51 of the locking element 1 (see Fig. 26).

[0086] Furthermore, two such elevations 55 can be provided for each wide area 47, 48.

[0087] Such elevations 55 can also provide a locking fixture when positioned appropriately due to engagement behind the edges of the slot opening (compare Fig. 26a).

[0088] In the securing position, the locking part 46 can be flush with the pot base 16 on the downwardly facing visible side of the pot base 16.

[0089] In order to be able to pull out the locking part 46 again in the opposite direction to the insertion direction S2 in order to release the securing position, an obliquely extending access opening 53 can be formed in the pot base 16 in association with the slotted opening 51, via which a tool, for example a screwdriver blade, can engage in a removal opening 54 passing through the wide surfaces 47 and 48 of the locking part 46, so that a lever can be used to overcome the holding forces by means of the tool.

[0090] Further point-like or dome-like elevations 56 can also be provided on the wide surface side of the locking part 46, offset from the elevations 55 in the insertion direction S2. These elevations (initially) prevent complete removal when the locking part 46 is moved back from the secured position opposite to the insertion direction S2 due to the elevations 56 abutting the edges of the slotted opening 51. The elevations 56 can be designed such that, with the appropriate force applied, they enable this locking position to be overcome (even when the locking part is first inserted).
