Description

[Detailed description of the invention] Technical field The present invention relates to a foldable table.

OBJECTS OF THE INVENTION The present invention provides a collapsible table that can be converted from a used state to a folded state or vice versa in a simple and quick operation, is compact in the folded state, and has a relatively simple and reliable construction. It's about doing.

Summary of the Invention In order to achieve the above technical problem, the present invention was constructed as follows.

That is, in the table of the present invention, the constituent members constituting the table are mutually foldably connected so that they can be unfolded into an arc shape around this axis from a folded state in which they are folded into a plane including an axis corresponding to the central axis of the table. The structure consists of multiple panels.

To further explain the configuration of the present invention in detail, the table of the present invention is as follows:
The structure of the table consists of a first group of mutually foldably connected panels forming a table top and a second group of mutually foldingly connected panels forming support leg members of the table top; The panels forming the table top plate are further foldably connected alternately to the panels forming the support leg members.

In the present invention, the panel forming the table top is generally flat. The panels forming the support leg members of the table top are arranged in a vertical plane that includes the central vertical axis of the table, and are foldably connected to each other around this axis, and the upper edge of each panel is In the folded state, a pair of panels corresponding to the respective panels of the table top board whose surfaces are in contact with each other are foldably connected to a common ridge. Furthermore, as one aspect of the present invention, 1. A pair of panels of a table top, one of which is hinged to each other, the opposite edges of which are foldably connected to two corresponding panels of a support leg member, and whose back surfaces contact each other when the table is folded. A pair of auxiliary panels each having an upper edge constituting a support surface for supporting the table when the table is in use is installed on each pair of panels of the support leg member.

Because of these features, the structure of the table can be easily and quickly converted from the folded state to the used state or vice versa. In fact, the transformation from one state to the other takes place in a single operation, without the need for assembly or disassembly of auxiliary parts. In the folded state, the table assumes a compact configuration. Furthermore, the above structure is simple and economical to manufacture and has high reliability.

A further advantage of the invention is that the table can be placed in a corner between two walls (table top corresponding to a 90° sector) or leaning against a wall.

This is because the table is manufactured with the assumption that it can be used in an intermediate state between the completely folded state and the normal use state, so that the table top plate corresponding to the fan shape of the table can be used.

A second aspect also includes an auxiliary panel inserted between each pair of adjacent vertical panels, the auxiliary panel being connected to connect to the vertical panel adjacent to the vertical axis of the table; It has an upper edge that supports six pairs of panels of the table top plate whose back surfaces are in contact with each other when the table is folded and when the table is unfolded.

By adopting each of the above aspects to the table of the present invention,
It is possible to ensure sufficient stability of the table in its usage state.

BRIEF DESCRIPTION OF THE DRAWINGS The features and advantages of the present invention will become clearer from the following detailed description, taken by way of example only and in conjunction with the accompanying drawings in which: FIG. Below, a table according to an embodiment of the present invention will be explained according to the drawings.

1 to 17 show tables according to the first embodiment. FIG. 1 shows a foldable table 1 comprising a table top 2 and support leg members 3 supporting the table top 2 during normal use. The table top 2 consists of a plurality of sector-shaped panels whose radial sides converge towards the central vertical axis of the table, indicated at 5. In this embodiment, the fan-shaped panel 4 is arranged so that its outer circumference forms a single circumference centered on the axis 5, and when the table is unfolded as shown in FIG. This is about a table.

However, it is clear that the panel 4 may be shaped so that the table top 2 has a different shape when the table is unfolded, for example square, rectangular or oval. . All of the panels 4 of the table top plate, except for two panels indicated as 4a in FIG. 1, are foldably connected at their radially adjacent sides like an accordion. The two panels 4a are not connected to each other, but only to the panels 4 adjacent to each other. Therefore, the table top 2 can be folded like an accordion from the state shown in FIG. 1 by an arcuate movement about the central axis 5 of the table. During this movement, two penel 4
a gradually moves away. The connections between each panel 4.4a are indicated by alternating numbers 6 and 7 in FIG.

When the table is folded (see Figure 5.9), the top surfaces of the two panels 4 adjacent to each connection 6 are in contact, and the second panel adjacent to each connection 7 is The back sides are touching.

The support leg member 3 supporting the table top 2 is foldably connected adjacent to the central axis 5 of the table, and includes a plurality of vertical panels 8 disposed in a meridian plane with respect to this axis.
It consists of Among these panels, the two panels indicated by 8a in the figure are not connected to each other, but are connected only to the adjacent panel 8. When the table is unfolded, the two panels 8a are adjacent to each other, and the pair of panels 8a and the other three panels 8 are arranged at an angle of 90° to each other (see Figure 4.10). ). The thickness of each panel 8a is preferably half the thickness of the panel 8, in which case the support leg member 3 holds four panels of the same thickness at 90 degrees relative to each other when the table is in normal use.
It is placed at an angle of 0°.

The upper edges of the three vertical panels 8 are connected to the three hinges 6 of the table top 2, while the upper edges of the two panels 8a are folded onto the free radial edges of the two panels 4a. freely connected. As a result of this construction and arrangement, when the table top 2 is folded like an accordion from its normal use position, the panels of the support leg members 3 rotate about their respective joints adjacent to the vertical axis 5 of the table; They are in an adjacent state as shown in FIG. This movement occurs naturally as the end panels 8a are gradually moved apart.

In order to ensure the strength necessary to support the panel 4 of the table top 2 on the hinge 7 when the table is in the unfolded state, two adjacent vertical panels of the support leg member 3 - a common A set of triangular auxiliary panels 9 is provided which are hinged at edges IO and each foldably connected to panel 8 at opposite edges 11. However, the two panels 8a are an exception, and since the table can be folded by completely separating them from each other, there is no auxiliary panel between these panels. When the table is in normal use, the upper edge of the auxiliary panel 9, indicated at 12, constitutes a support surface that supports the two panels 4 immediately above. The stability of the table top plate 2 is thus ensured under the normal use of the table.

The attached FIGS. 1θ to 17 show the detailed structure of the table explained in the above embodiment. Obviously, such detailed construction may be varied without departing from the scope of the invention.

With reference to FIG. 10, the panels 8.8a of the support leg member 3 are foldably connected by four vertical M13s located approximately equidistant from the central vertical axis 5 of the table. Each connecting portion 13 is constituted by a conventional metal hinge 14 consisting of two hinge elements extending over the entire length of the panels 8, 8a, each having a hole into which a connecting pin is inserted. The two hinge elements I5 of each hinge 14 are provided with side flanges 16 which are fixed to the respective panel 8.8a with rivets 17. In order to hide the metal hinges 14 from view when the table is folded, a specially shaped element 18 made of a deformable elastomer is connected to each hinge 1.1 and also connected to each panel 8 with rivets 17. It also has a vertical flange, designated 19, which is fixed to 8a.

Figure 1L shows the detail of Figure 10 with the table folded and the element 18 deformed.

FIG. 12 shows a detailed cross-section of the connection 6 between two adjacent panels 4 of the table top. As is clear from FIG. 12, the connection 6 between two adjacent panels is actually realized by a pair of hinges 20, by means of which the two panels 4 are connected with two parallel axes 21, It is foldably connected to each panel 8 of the support leg member 3.

Each of the two hinges 20 consists of two sheet metal hinge elements 22 whose respective flanges are inserted into channels 23 formed in each panel 4.8. A hole 24 is formed in each panel 4, 8, and a flange 22
In order to prevent the flange from coming out of the channel 23, the flange 22 can be crushed with a tool.
