Abstract

The table has a top which consists of a sheet (21) of flexible material which is held taut by supporting bars (41) underneath it. These fold upwards like an umbrella frame so that the top can be stored in the table leg (3).

Description

The invention relates to a collapsible table with a table surface and a frame supporting the table surface.

For spontaneous and mobile use, there are hardly any light and space-saving constructions of tables. Applications for this are available in many areas. For example, at trade fairs or presentations to be prepared for a short time, tables and shelves are in demand that can be provided quickly and without problems. Even in the leisure sector, light and easy to transport tables are easy to use. For example, outdoor parties or picnics are often cumbersome, as tables that are too heavy or too bulky must be taken or procured.

It often does not depend on the carrying capacity but rather on the spontaneous applicability and the lightweight construction.

From DE-OS 35 23 393 A1 a collapsible travel table is known, in which the existing of rigid individual elements table surface can be pushed into one another like a fan. From its construction, this known table is very limited use and also offers little floor space.

From DE-OS 199 02 223 A1 a collapsible table has become known in which the table top consists of a plurality of coupled by hinges, side by side arranged table leaves, whereby the table top blinds-like is collapsible. By design, this table requires very rigid and stable table leaves, which these become heavy and the collapsibility is limited.

From JP-AA 2000 135 120 a table for outdoor use has become known, which has a collapsible leg construction on which an existing narrow narrow panels, can be placed in one direction rollable plate.

US-A 5,425,315 shows a foldable table which suggests the use of a mechanism known from umbrellas. Here are centrally hinged rigid lamellae, which form the surface of the table, supported from below by a frame clamped by a complicated mechanism. Because of the high weight and large forces in individual joints, this design is possible only in metal, making it again difficult and limited use.

From US 6,536,732 B1, a pivoting mechanism for collapsible furniture has become known in which a collapsible table has a table surface which is supported by a collapsible frame, wherein the folding arms are pivoted relative to the table surface in a pivot bearing.

The US 5,421,273 shows a collapsible table, in which a mating tubular construction spans and carries a flexible table surface.

All previously known solutions have in common that the constructions are unwieldy. In some cases, the proposed solutions are also very difficult due to the mandatory material specification in metal, which makes them only partially usable for flexible use.

The invention is therefore based on the object to provide a comparison with known constructions improved collapsible table available, in which conditionally more cost-effective materials are used in particular by the construction.

This object is achieved by a collapsible table according to claim 1.

According to the invention it is provided that the frame has an elongated hollow body as a support body, wherein the support layer with the folding arms with fully folded pivoting of the folding arms in the hollow body of the frame can be inserted or retracted.

The invention proposes to circumvent the rigid table tops or rigid table tops divided into individual segments by mounting a flexible support layer by forming a table surface. As a result, lightweight and flexible materials for use are possible, whereby a very lightweight and small collapsible construction is possible. The folded table surface is in the hollow body of the frame inserted or retractable designed. The table is therefore easy and space-saving foldable and foldable, easy to transport and is easy and fast to build according to the occasion and need.

The table is also optimized for transport so that the table surface and the feet can be integrated within the frame. The table can be transported in a minimal space.

The possibility to use lightweight materials for the table surface and thus also for the folding arms and the frame, since they no longer have to carry the high weight of a table top, is a problem-free portable design makes it possible to use the collapsible table universally in leisure time, outdoors (camping, hiking, picnics, ...) or for example at trade fairs as a bistro table or as an occasionally available side table. The cost-effective manufacturability of the table is also ideal as an original giveaway.

The same reference numerals in the figures designate the same or equivalent elements.

1 to 4 show the collapsible table 1 according to the invention with a flat surface formed by a flexible support layer 21 formed table surface 2 and a table supporting the frame 3. The support layer 2 is in the first representation of FIG. 1 hidden folding arms 41 of worn down.

The table stands on the floor and is stabilized by means of the bottom of the support body 31 of the frame 3 attached support device 5 by the laterally projecting Ausstellbeine 51.

The material of the base layer 21 should be dimensionally stable, tear-resistant, tensionable, weather-, temperature- and UV-ray resistant, e.g. Fabric, fabric, rubber, silicone, plastic, paper, cardboard.

The materials can also be used in lamella form. The basic shape of the table surface can be three-, four-, five- and hexagonal, etc. or round.

The frame, the folding arm and the legs and the connecting elements are made of solid materials that are suitable for the design and stabilization of the table to choose. These materials may, for. As: metals, plastics, rubber, silicone, wood, resins.

A side view of the assembled table is shown in Fig. 2.

In Fig. 3, the table 1 is shown in a view from below. To stabilize the circumferential edge of the support layer 21 and the distances between the ends of the folding arms 41 is a circumferential tensioning cable 23 is provided, which is attached to the ends of the folding arms.

Fig. 4 shows the table 1 seen from above.

A view of the partially folded support layer 21 and partially folded Ausstellbeinen 51 is shown in Fig. 5. To fold down the folding arms 41 are simply folded vertically upwards to the perpendicular bisector of the table towards each other, as indicated by the arrows. Likewise, the procedure is with the Ausstellbeinen.

Fig. 6 shows a stage in which the folding arms and thus the support layer 21 is still folded further. The Ausstellbeine 51 are shown completely folded. In this position, the deployment legs can also serve as a peg, which are then plugged into the table supporting the ground. In this illustration, a transparency was chosen to better understand the spatial relationships.

For further collapsing the bearing body 4 is withdrawn with the attached folding arms 41 and the supporting layer 21 attached thereto from the support body 31 and turned over (arrow A). Likewise, the support device 5 is moved (arrow B).

Fig. 7 shows the state then reached. For further collapsing, the support layer 21 with the folding arms 41 continues to be folded toward one another (arrow A) and inserted in a further step into the hollow space of the support body 31 designed as a hollow cylinder (arrow B). Also, the support device 5 can be inserted in the same way with the Ausstellbeinen 51 ahead in the cavity of the support body 31.

The further Figures 8 to 11 show in detail the sections VII, IX, X and XI of Fig. 6 and 7.

8 shows a more detailed illustration of the bearing body 4 with the folding arms 41 hinged thereto in each case in a pivot bearing 42. The folding arms 41 are guided for stabilization in a slot guide 45 which is parallel to the pivoting direction. This prevents tilting of the folding arms 41 during pivoting. The final ends of the slot guides 45 form the supports 43 for the folding arms 41 in which they are supported in the fully unfolded position.

The bearing body 4 is inserted with its cylindrical lower part (see Fig. 9 in the pulled-out state) in the cavity of the support body 31 up to its stop bead 47 in a position defined thereby.

10 and 11 shows in detail the support device 5, which is inserted in Fig. 10 up to the stop bead 56 with the cylindrical part (see FIG. 11) in the cavity of the support body 31. The deployment legs 51 of the support device 5 are mounted in leg pivot bearings 53 and are guided in leg slot guides 57. In the fully extended state, a support 54 for the Ausstellbeine 51 is formed by the final end of the leg slot guide 57.

Fig. 12 shows a view of the completely folded table 1 with inserted in the support body 31 bearing body 4 and inserted support device 5. The table is thus reduced to a minimum space dimension.

FIGS. 13 and 14 show in more detail that the bearing body 4 on the one hand (detail XIV of FIG. 12) and the supporting device 5 on the other (detail XIII of FIG. 12) are again inserted in each case up to their circumferential stop bead 47 or 56 ,

The merging as the construction succeeds by these precautions error-free.

In Fig. 15 the collapsed table 1 is shown in a see-through view. The space in the hollow formed support body 31 is used optimally, the table is optimally merged into the smallest dimensions.

16 and 17 show in an enlarged view the areas of the inserted bearing body 4 and the inserted support device 5 of Fig. 15 (detail XVI and XVII).

In Fig. 18 is a schematic view obliquely from above on the Entland for illustration entland its mid-perpendicular partially exploded fully unfolded table 1 is shown. The table surface 2 forming support layer 21 is attached to the facing her upper sides of the folding arms 41. The revolving tensioning cable is attached to the ends of the folding arms 41 and serves for stabilization. The support layer 21 is connected by means of the fastening means 22 in its center at the puncture point of the perpendicular bisector M of the table surface 2 with the bearing body 4.

In the following FIGS. 19 to 23b, the bearing body 4 according to detail detail XIX and the support device 5 will be explained in more detail with reference to FIGS. 24 to 28b corresponding to detail detail XXIV and XXV.

Fig. 19 shows the detail XIX of Fig. 18. The fastener 22 attaches the support layer at the piercing point of the perpendicular bisector M with the bearing body 4 by its inserted into the receptacle 222 of the bearing insert 48 extension 221. Since the folding arms 41 also connected to the support layer are, the folding arms are limited in their relative movement. The folding arms 41 are held in the slot guides 45 by their pivot bearings 42 through held in the introductions 46 of the folding arms 41 bearing ring 44, wherein the bearing ring 44 in a bearing-ring bearing 441 (see also Fig. 22 b) comes to rest. By held in the introductions 46 bearing ring 44 and the limited by the connection to the bearing body 4 support layer 21 possibility of mutually relative movement, the folding arms 41 are also only through the slot guide perpendicular to the perpendicular perpendicular M movable. By the cross-sectionally T-shaped configuration (see also Fig. 29 c) of the folding arms 41, the top of the bearing insert 48 forms a support 43 for the fully deployed folding arms 41st

Fig. 20 a and 20 b show the fastening means 22 in a side view and from above.

Fig. 21 a and 21 b show the bearing ring 44 in a side view and from above. The bearing ring 44 respectively forms the axis of the annularly arranged pivot bearing 42 of the folding arms 41. The bearing ring 44 is made of rubber, so it can compensate for any occurring bearing forces optimally.

FIGS. 22 a and 22 b show the bearing insert 48 in a side view and from above. In the bearing insert 48, the slot guides 45 are designed as recesses, at the lower end thereby form the annularly arranged supports 43 for the folding arms 41. In a smaller radius than the supports 43 of the folding arms 41, the bearing-ring bearings 441 are arranged. The receptacle 222 for the extension 221 of the fastening means 22 is arranged centrally.

Fig. 23 a and 23 b show the lower part of the bearing body 4 on which the stop bead 47 is formed in a side view and from above. In this example, the receptacle 222 for the extension 221 of the fastening means 22 is also continued in this part of the bearing body.

FIGS. 24 and 25 show the detail XXIV and XXV of FIG. 18. The support device is shown in its individual parts. The leg bearing body 52 is similar in construction to the bearing body of the folding arms. The Ausstellbeine 51 are guided in formed in the leg-bearing body 52 leg slot guides 57, whereby the Ausstellbeine 51 are only vertically folded. The bearing ring 55 forming the bearing shafts of the leg pivot bearings 53 is held in a bearing-ring bearing 551 in the form of a circular groove, which is in one end plate and the other in the upper part of the leg bearing body (see FIG. 26 b) is executed. The bearing ring 55 is inserted analogously as in the folding arms each in an introduction 59 of the raising legs 51. The bearing ring held in the grooves and the slot guides thus form a defined and mechanically secure guidance.

FIGS. 26 a and 26 b show the upper part of the leg bearing body 52 in a side view and from above. In this part of the leg bearing body 52, the leg slot guide 57 is opposed to the leg slot guide of the end plate 58 (see FIGS. 28 a and 28 b). Outer circumferentially the stop bead 56 is formed. The bearing-ring bearing 551 is formed in the form of a circular groove.

Fig. 27 a and 27 b show the bearing ring 55 in a side view and from above. The bearing ring 55 forms in each case the axis of the annularly arranged leg pivot bearings 53 of the Ausstellbeine 51. The bearing ring 55 is also made like the bearing ring 44 made of rubber, it can optimally compensate for any occurring bearing forces.

Fig. 28 a and 28 b show the end plate 58 in a side view and from above. In the end plate, the leg slot guide 57 is also formed. Only the webs 571 connect the individual sections of the end plate 58. The webs 571 form, together with the ends of the leg slot guide cuts in the upper part of the leg bearing body (see FIGS. 26 a and 26 b) the support 54 of the deployment legs 51. These are arranged so that the release legs 51 in a Angle of less than 90 ° against the perpendicular bisector M of the table surface 2 are fully unfolded. As a result, the legs offer an optimal stand of the table.

FIGS. 29a, 29b and 29c show a plan view from above, a lateral plan view and a side view in the direction of extension of a folding arm. The T-shaped cross-sectional profile ensures good stability of the folding arm. The Ausstellbeine are also designed as the folding arms.

Fig. 29d shows a schematic cross-sectional view through the bearing body 4 with folding arms 41 and by means of the fastening means 22 on the bearing body 4 fixed support layer 21 in the fully unfolded state. In this illustration, the pivot bearing, which is guided by the bearing ring 44 of the leads 46 of the folding arms 41, can be seen particularly well. The bearing ring 44 is located in the bearing ring bearing 441. Up the bearing ring 44 must not be fixed because it is connected by the folding arms 41 which are connected to the support layer 21, which again with the fastening means 22 with the bearing grains 4 is connected, is fixed.

A variant of the collapsible table 1 according to the invention is shown in greater detail in FIGS. 30 to 53.

The design of the folding mechanism of the folding arms 41 and the Ausstellbeine 51 is carried out as in the variant already shown, therefore, only the differences are discussed in more detail.

In this variant of the collapsible table 1, the bearing body and the support device are not removed and inserted vice versa in the hollow support body 31, but there is a positive guide in the form of guide slots 61 and 62, with which the bearing body and the support device are inserted into the support body ,

Fig. 30 shows a table with fully folded Ausstellbeinen 51 and almost completely folded Klapparmen 41 attached thereto support layer 21. On the end cover 70 and the strap 8 will be discussed later.

The bearing body 4 is displaceably mounted in the support body 31, wherein the bearing body 4 is connected to an externally on the support body 31 slidably guided guide ring 64 by means of a guide slot 61 reaching screw. As a result, a positive guidance for the bearing body 4 is formed. To accommodate the supporting forces 31 a screw 631 is provided at the end of the support body which forms a termination stop 63 for the bearing body 4, so that the forces are not derived via the forced operation with unfolded table surface.

In the same way, a positive guide with the guide ring 65 and the guide slot 62 is formed for the support device 5, as shown in Fig. 32 in an enlarged view of the section XXXII of FIG. 30. Again, to accommodate the supporting forces is at the end of the support body 31 a screw 631 is provided which forms a termination stop 63 for the support device 5, so that the forces are not derived through the forced operation in unfolded Ausstellbeinen 51.

Fig. 33 shows the table of Fig. 30 with schematically individually shown items.

Fig. 34 shows an enlarged view of the range XXXIV of Fig. 33. The guide ring 64 is connected to the bearing body 4 by a protruding through the guide slot 61 bolt or a screw in a provided in the guide ring 64 and a 642 in the lower part of the Bearing body 4 provided bolt abutment 641 is mounted.

Fig. 35 shows an enlarged view of the range XXXV of Fig. 33. The guide ring 65 is connected to the support device 5 by a protruding through the guide slot 62 bolt or a screw in a provided in the guide ring 65 thread 652 and one in the upper part of Leg bearing body 52 provided bolt abutment 651 is mounted.

FIGS. 36 a and 36 b show the end cap 70 in a side view and from above. The end cap 70 is placed with retracted table surface and support device on the openings of the support body 31 and closes off this sealing. On the end cover a push button receptacle is formed on which the strap can be attached.

FIGS. 37 a and 37 b show the screw-in ring 631 in a side view and from above.

Figs. 38 a and 38 b show the bearing ring 44 in a side view and from above.

FIGS. 39 a and 39 b show the bearing insert 48 in a side view and from above.

40 a and 40 b show the lower part of the bearing body 4, in which the bolt abutment 641 is formed, in a side view and from above.

41 a and 41 b show the lower part of the guide ring 64, in which the thread 642 is formed, in a side view and from above.

42a and 42b show the upper part of the leg bearing body 52 in which the bolt abutment 651 is formed, in a side view and from above.

FIGS. 43 a and 43 b show the bearing ring 55 of the support device in a side view and from above.

Figs. 44 a and 44 b show the end plate 58 in a side view and from above.

FIGS. 45 a and 45 b show the screw-in ring 631 of the support device in a side view and from above.

In Fig. 46 is a side view and a top view obliquely from above of a fully collapsed table 1 according to the second variant with positive guidance. With the carrying strap 8, the easily executed table can be easily carried.

The guide slots 61 and 62 are made horizontally at their ends 612 and 622, whereby the guide ring 64 and 65 must be rotated along the positive guide. As a result, a locking of the bearing body 4 and the supporting device 5 is achieved, so that they can not be accidentally returned back into the hollow body of the support body 31.

Fig. 48 shows in detail the area IID of Fig. 46. The two guide rings 64 and 65 are completely withdrawn and touch.

FIG. 49 shows in enlarged detail the area ID of FIG. 47.

FIG. 50 shows in enlarged detail the region D from FIG. 47.

In Figs. 51 and 52, the views of Figs. 46 and 47 are shown in phantom. The support layer 21 is retracted with the folding arms 41 and the bearing body in the support body. Likewise, the support device is completely housed in the hollow body of the support body.

FIG. 53 shows in accordance with FIG. 48 the region DIII from FIG. 51 in a phantom representation.
