Abstract

FIELD: personal use articles.

SUBSTANCE: camp portable folding table is designed to be used in field conditions, including in long hiking tours, geological and other expeditions where weight and size of equipment is of particular importance. It has the surface of the table with the rigid portions and flexible cloth in the working position with minimum sizes and weight of the table in the hiking position. It can be used for picnics with a different number of participants, which may be unlimited, and depends on the configuration of the table by the number of identical basic elements, and the size and weight of the table in the folded, hiking position is not increased significantly. Essence of the invention: the base element of the table is taken as a set of identical thin metal sheets forming a hard table circuit for stable, horizontal placement on it of objects of hiking dishes with liquid food, and a fastener of flexible table cloth. The ends of the sheets are made at angles of 30º to the longitudinal axis of the sheet for assembly of tables of various sizes. The longitudinal edges of the sheets are bent at a right angle to the sides opposite to each other for rigidity of sheets and compactness of laying them in the hiking position of the table. The sheets are assembled together in a circuit using three identical openings formed at the ends of the sheets with simultaneous installation of the table racks and fastener of the flexible cloth, on which the items are placed, that do not require a stable horizontal position. In the hiking position, the table is folded into two compact packets.

Description

The invention relates to traveling camping and portable tables, namely to portable camping folding tables.

Known folding table (patent SU No. 1546072 A1, IPC A47B 3/091, 02/30/1990) containing a countertop, two pairs of intersecting articulated legs and transverse legs. The table has the ability to fold for transportation. However, the ratio of the usable area of the table to the area of the table in the folded, transported condition here cannot be less than one, because the area of the countertop does not change, only the height of the table decreases during transportation when folded. In addition, the dimensions of the table, its usable area are limited by the dimensions of the transportation. The table has a significant weight, determined by its design, limiting the distance over which it can be transported.

The closest in technical essence and the achieved result to the proposed portable portable folding table is a convertible folding seat - a table (RF patent No. 2020849, IPC A47B 3/10, A47C 4/40, A47C 9/10, 10/15/1994) adopted for a prototype and including racks with pins extended from them, where a flexible tabletop is attached.

The disadvantages of the described design are:

a) Small area of the table in relation to the size of the rest of the structure, providing support for the plane of the table.

b) Irrational, triangular shape of the table. Changing the shape of the table to a more rational (quadrangular or more) will lead to a significant complication of the supporting structure, an increase in its weight and dimensions.

c) The absence on the table plane of hard surfaces necessary for installing dishes with liquid food, making notes, etc.

The objective of the invention is the creation of a portable camping folding table with a large usable area relative to the rest of the supporting structure, the presence of hard sections of the table in the assembled state with its minimum dimensions and weight in the stowed position. It was also envisaged that it would be possible to manufacture a table with a larger area by increasing the number of typical elements while maintaining its portability and minimal weight in the stowed position and without the need to use any tool for assembling and disassembling the table.

The problem is solved in that a thin (1.5-2 mm) metal (preferably aluminum alloys) sheet is selected as the main element of the table. The sheet has a width sufficient to accommodate the necessary dishes with liquid food (100-200 mm). The long sides of the sheet are zigzag bent in opposite directions to give the sheet rigidity and the possibility of compact stacking of a set of sheets in a stack when in the stowed position. A set of sheets assembled using racks and clamps forms a rigid contour of the table, inside of which a flexible table cloth is stretched and attached using a clamp. To ensure the possibility of a rigid and rational contour of hexagonal tables (approaching a circular one), the ends of the sheets are cut at an angle of 30 ° to the longitudinal axis of the sheets with three mounting holes being made at both ends of the sheet at equal distances from the ends of the sheets and at an angle of 60 °. These holes are used to assemble sheets together with overlapping ends and aligning the holes where the threaded part of the table racks and the clamps of the flexible table panel are installed. The top, working, plane of the table is supported only by racks extending down from the sheets, 1 pc. on the sheet.

In addition, the specified shape of the sheets allows you to collect the contour of the table of almost any length, which will require only an increase in the number of identical sheets and racks of the table with a corresponding increase in the length of the flexible table panel with clamps. In this case, the end sheets of the table are assembled as described above, and the linear part of the table is assembled by turning the sheets around its longitudinal axis through one sheet and after 2-3 sheets spacers are installed to maintain the rigidity of the long contour of the table. Spacers are installed at the joints of the sheets in the middle holes of the ends of the sheets.

Also, the middle holes at the ends of the sheets can be used to better balance the tables when they are heavily loaded - here you should install the table racks, which will be closer to the center of the table.

When assembling a table of any length, including a hexagonal one, sheets should be collected so that the edge of the sheets bent upwards always faces the flexible table cloth, and the bent downwards - outside the table.

In the stowed position, the table sheets are stacked, which is wrapped in a flexible table cloth, the table racks are tied in a bag or placed in a bag, convenient for transportation.

The causal relationship between the set of essential features of the claimed invention and the achieved results is as follows.

The use of flat rigid elements, sheets in the design of the table provides the ability to:

- creating flat rigid elements on a part of the table;

- creating a rigid contour around the table perimeter providing fastening and tension of the flexible table cloth, significantly increasing the table plane with the installation of a minimum number of table racks.

The configuration of the sheets provides the ability to assemble tables of various sizes.

The same flat, with a zigzag bending of the edges, the configuration of the sheets provides compact stacking of sheets in a stack during transportation.

In addition, the elements of the table are simple and technologically advanced to manufacture. The invention is illustrated by drawings.

In FIG. 1 shows a top view of a hexagonal table; in FIG. 2 - side view A of the table; in FIG. 3 - the basic element of the table is a sheet in a plan view; in FIG. 4 - a sheet in the form of B from the end; in FIG. 5 is a view B with a sectional view of a typical element for connecting table elements; in FIG. 6 - option of assembling a table of increased area; in FIG. 7 - an option of assembling a table of large length; in FIG. 8 - section GG at the place of installation of the spacer for tables of large length; in FIG. 9 - view D with a spacer mount; in FIG. 10 is a view E showing the junction of the halves of the strut tube.

The portable portable folding table consists of a set of sheets 1, which are the main basic element of the table, table racks 2, flexible panel 3 with clips 4 sewn to it.

Sheets 1 are made of a sheet of metal with a thickness of 1.5-2 mm (preferably from aluminum alloys to reduce the weight of the table and comply with hygiene requirements). The width of the flat part of the sheets is selected based on the possibility of placing dishes with liquid food on it (usually from 100 to 200 mm). The magnitude of the bends along the length of the sheets (see Fig. 4) is 10-15 mm. The length of the sheets determines the area of the table assembly and, taking into account the convenience of transportation, is accepted up to 500 mm.

To create a hexagonal shape of the working plane of the table, as the most rational, approaching in a round, the ends of the sheets are cut at an angle of 30 ° (see Fig. 3) and three holes are made at the ends for subsequent assembly of the table. The holes are made with equal distances between them and at an angle of 60 ° between them. To reduce the mass of the sheets and remove debris during operation, it is advisable to make holes 5 on them, which practically do not reduce the rigidity of the sheet due to the presence of bends in the edges of the sheet.

In FIG. Figure 5 shows a node for the joint of sheets 1, typical for all table configurations. Sheets 1 are joined with an overlap at their ends with a combination of holes for table posts 2 and clamps 4. Table posts 2 consist of a rod 6 of a thrust washer 7, fixed on the rod 6 with fixing glue , and the wing nut 8. The clamp 4 consists of a flat plate 9, a plate with a bend 10 for ease of assembly of the table, textile tape 11, fixed between the sheets 9 and 10 by rivets. In the threaded hole made after riveting the plates 9, 10 and tape 11, a screw 12 with the same thread as on the table stand is installed on the fixing glue. The clip set includes the wing nut 8, the same as on the table leg. A flexible panel 3 is sewn in place to the textile tape 11 clips 4.

In FIG. 6 shows a variant of the table with an increase, compared with the hexagonal table, by 4 by the number of sheets 1 and equal to 10. Accordingly, the length of the flexible panel is increased and the number of racks of the table 2 is equal to ten. The end sheets 1 are assembled similarly to the hexagonal table, the sheets 1, average along the length of the table, during assembly are rotated 180 ° around the longitudinal axis of the sheets and are installed, like other sheets, by bending upward towards the center of the table and bending downward towards the edge of the table.

In FIG. 7 shows a long table that is assembled, like the table in FIG. 6, but in order to maintain the rigidity of the circular belt of sheets 1 and to ensure the necessary tension of the flexible panel having a large length here, spacers 13 (see Fig. 8) are installed through 2-3 sheets along the length of the table, passing under the flexible panel and fastened with their threaded ends 14 (see Fig. 9) to the middle holes at the joints of the sheets 1.

The spacers 13 consist of a tube 15 with fixed tips 14, having the same thread as on the racks of the table, and the wing nuts 8.

To maintain the compactness of the table in the stowed position, the tube 15 of the spacers 13, having a longer length relative to other parts of the table, is made of two parts approximately equal in length with the connection using a round insert 16 (see Fig. 10). The insert 16 is mounted in one of the parts of the tube 15. The two parts of the spacer 13 when disassembling become comparable with the length of the sheets 1 and the racks of the table 2 with the stowed position of the table.

Using the claimed invention will improve the living conditions of participants in hiking, geological and other expeditions, as well as allow more comfortable to conduct various picnics.
