Abstract

Extendable telescopic table that does not require supplementary board, whose board is formed by narrow longitudinal strips (11 and 14), in contact with each other and grouped alternately in two sets (1 and 2), thus forming the useful surface of the table. Each group of strips (11 and 14) is joined by its lower face to two frames formed by crosspieces (5, 6 and 7) (12 and 15) and stringers (8, 9 and 10) (13). These two frames fit one inside the other. The stringers of these frames (8 and 13) have, along their contact faces, grooves and tabs that serve to guide the movement between the two sets (1 and 2) that form the tabletop. Once the board has been assembled, these two assemblies (1 and 2) are joined, by pulling on either end, they slide together guided in the longitudinal direction, thus increasing the length of the board and with it its useful surface, without the need for a board or supplementary elements. This route, and with it the extension of the board, is limited both in the minimum and maximum position by the contact between the crosspieces (5, 15 and 6) of the two frames. Finally, the legs (3 and 4) are joined to the two crosspieces at the ends (5 and 12) of the board. When the board is extended, the legs (3 and 4) also move, thus releasing the maximum space under the table for easy use. (Machine-translation by Google Translate, not legally binding)

Description

Telescopic extendable table that does not require supplementary board.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a table extensible whose extension system has been designed to allow increase its useful surface lengthwise so telescopic This means that the extension can be made from gradually being able to stay in any intermediate position between the minimum and maximum extension, according to the needs of the Username. Another quality is that it does not require a board or elements supplementary to increase the useful area.

The extension system is based on a board formed from narrow longitudinal slats, the which alternately join two frames formed by stringers and crossbars. These two sets slide each other in longitudinal direction thanks to a guided system, increasing from This mode the board length.

Background of the invention

Wide variety of table systems are known extensible: with fixed or extensible armor; with boards extendable by sliding, extraction, folding or folding; with supplementary recessed, swing or sliding boards. In In all these cases, the extension to user will and is limited by the length of the supplementary boards. In addition, placement operations and saving of the supplementary elements are somewhat cumbersome

Extensible blind tables are also known articulated In these cases they usually allow the extension to be done. gradually. They consist of a part of one or two boards main and other supplements formed by joined tablets by way of blinds that move through guides and remain hidden when the table is in an extended position. In these cases, by pulling one end of the board to get the extension, the effort falls mainly on the union between the shutter and main board, this being the weak point of system.

All the above mentioned tables have in common that have one or more main boards, and all they need additional elements to increase their surface Useful. These supplementary elements, which normally go hidden under the main board, they are removed and placed at the level of Main board to extend the useful surface of the table.

Description of the invention

The extensible system of the invention presents a new structure thanks to which it is achieved on the one hand extend the useful surface of the table telescopically, which allows to gradually regulate its length in any position intermediate between the minimum and maximum extension according to needs, and on the other, avoid using boards or supplementary elements to expand its useful surface, since it get from the elements that make up the board already existing.

The extension system is based on a board formed from narrow longitudinal slats, the which alternately join two frames formed by lateral stringers and crossbars. These two frames are placed one inside and outside. The extension operation is very simple, by pulling any of the ends of the table these two sets of slats slide each other in longitudinal direction thanks to a guided system, thereby increasing the length of the table and with it its useful surface. By pulling the ends the force is distributed equally over all slats and stringers, it is This is why the system is structurally strong and resists Perfectly extending and closing efforts.

These two sets that make up the board cover the total table surface in position no extended. As it spreads, they remain at each end of the board a grid-like area, formed by the displacement of the slats, whose grooves are narrow enough not to prevent normal use of the table surface. In the zone Central is a continuous surface without grooves.

The legs are attached to the crossbars of the extremes When you extend the table, the legs move at the same time, freeing up the maximum space under the board.

Description of a preferred embodiment

In view of the commented figures, you can observe how the table is composed of a board, formed at its once for two sets of pieces 1 and 2, each of them are joined two pairs of legs 3 and 4. The aforementioned sets 1 and 2 have two frames that fit inside each other allowing between they a sliding movement guided in the longitudinal direction, with a limited path between a minimum and maximum position, as see in Figures 1 and 2.

The first set 1 of the board is composed by a main crossbar 5, which is at one end of the board and is to which a pair of legs 3 will be attached; at the other end of set 1 is a frame formed by two crossbars 6 and 7, and by two symmetrical stringers 8, which carry a groove along its the outer face that will serve to guide the movement between the two sets 1 and 2 that form the board; two stringers lateral 10 that are joined by a part to the main cross member 5, and on the other they are joined, by two pieces 9 of section L, to the stringers 8 on the corresponding side of the frame. Finally, a group of narrow longitudinal slats 11 of equal dimensions they join the three crossbars 5, 6 and 7. These slats 11 are placed parallel and distanced from each other the same distance as their own thickness. This completes the assembly of the first board set 1.

The second set 2 of the board is composed by a main crossbar 12, which is at the other end of the board and is the one that will join the other pair of legs 4; two lateral stringers 13 symmetrical that join each end of the main crossbar and that have a tongue along their inner face that will serve, together with the groove of the stringers 8 of the other set, to guide the displacement between the two sets 1 and 2; a group of narrow longitudinal slats 14, of the same dimensions as the slats 11 of the other set 1, which are also parallel and spaced the same distance as their own thickness and joined by one of its ends to the main crossbar 12.

At this point of assembly, and in the absence of join the last crossbar 15 to this set 2 of the board, the two sets 1 and 2 fit and slide together until they reach the non-extension position, in which the last cross member 15 joins the lateral stringers 13 and the free ends of the slats 14 of the second set 2. This last crossbar 15 is located between the main cross member 5 and center 6 of the other assembly 1. After joining this crossbar 15 to its corresponding pieces 13 and 14 the assembly of this assembly 2 is completed.

The two sets 1 and 2 that make up the board they are united being able to slide each other. The top of the tour for the minimum extension position is made by the contact of the inner crossbar 15 of the second set 2 with the crossbar main 5 of the first set 1. The top of the course for the maximum extension position is made by the crossbar contact interior 15 of the second set 2 with the central cross member 6 of the first set 1.

Legs 3 and 4 can be disassembled to facilitate transport A pair of legs 4 can carry wheels for facilitate sliding in the table extension movement. On the inside of the main crossbars 5 and 12 that remain located on the ends of the board can be made handles dug to facilitate grip for extension. Fits the possibility of incorporating a locking system to keep fixed the position between the two sets 1 and 2 that form the board, in Any extension position.
