DE10051288C1 - Coupling device, for adjacent stools or chairs, has slider acting as panic lock preventing release of coupling elements after clipping together - Google Patents

Abstract

The coupling device (2) has cooperating coupling elements (3,4) fitted to the undersides of both stools or chairs to be coupled, for movement along guide rails into contact with end stops (10), with their projecting free ends clipped together. The end stops are provided by U-shaped clips fitted into different positions relative to the coupling elements, at least one of the coupling elements provided with a slider (15) for securing the clipped coupling elements together.

Description

The invention relates to a connecting device for the production of rows of chairs and / or armchairs with among the Chairs or armchairs attached, which can be coupled and detachable interlinking elements that define the distance Define adjacent chairs or armchairs.

Such a series connection is for example from DE 198 48 423 A1 known. The linking elements exist made of wire brackets, with their free ends freely into each other are hooked and therefore not against unintentional unhooking are secured.

The invention has for its object a Connection device of the type mentioned above train that an easy to use and against unintentional unhooked secured row connection between Chair and chair or between chair and armchair, which is therefore safe in the event of a panic.

This object is achieved by the Characteristic features of claim 1 solved.

Appropriate developments of the invention are the See subclaims.  

All parts of the connecting device consist of unbreakable plastic.

An embodiment of the invention will now be referred to described on the drawings. It shows

Figs. 1 and 2 show, once from below (Fig. 1) and once from the top (Fig. 2) two chairs 1, which are concatenated with the connecting device, generally designated 2. The connecting device 2 consists of two interlinking elements 3 and 4 made of unbreakable plastic, of which one interlinking element 3 is shown in FIG. 3 and the other interlinking element 4 in FIGS. 4 and 5.

One interlinking element 3 ( FIG. 3) has hook 5 angled outwards at one end and the other interlinking element 4 ( FIG. 4) has angled hook 6 . In the assembled state ( FIGS. 7 and 8), the outwardly angled hooks 5 of one interlinking element 3 engage in the inwardly angled hooks 6 of the other interlinking element 4 , these inwardly angled hooks 6 each having a bottom 7 as a stop for the have hook 5 angled on the outside of one interlinking element 3 (see FIG. 5).

The interlinking elements 3 , 4 have guide strips 8 with which they can be pulled out in guide rails 9 of the chairs 1 up to U-shaped stops 10 under the respective chair 1 . One of these stops 10 , which are designed as U-shaped clips, is shown in FIG. 10 and has barbs 11 with which it is clipped into recesses 12 or 13 , which are located in the interlinking elements 3 , 4 , namely there are two pairs of recesses 12 , 13 in each of the interlinking elements 3 , 4 , the relevant stop 10 being clipped either into one pair of recesses 12 or into the other pair of recesses 13, depending on the desired or necessary chair or armchair distance, after of course the relevant linkage element 3 or 4 has been inserted into the guide rails 9 of the chair 1 or armchair.

FIGS. 6 to 8 show in side view the assembly of the linkage members 3, 4. In Fig. 6, the two linking elements 3 , 4 are in a position before hooking, while they are joined together in Figs. 7 and 8.

The other interlinking element 4 , which is shown in detail in FIGS. 4 and 5, has U-guides 14 for displaceably receiving a slide 15 serving as "panic protection", which is shown separately in FIG. 9 and in FIG. 4 and 5 is omitted. The slider 15 has barbs 17 on resilient tongues 16 , which hold the slider 15 captively in the U-guides 14 . In addition, the slide 15 has a handle extension 18 , on which the slide 15 can be pushed in the locking position (arrow in FIG. 7), as shown in FIG. 8. In this position, the slide 15 prevents unintentional detachment of the linking elements 3 , 4 from one another. The slide 15 expediently consists of red plastic.

The slide for panic protection can secure a place number plate 19 at the same time. This is made of plastic and has an L-shaped projection 20 on the underside, which is inserted from above into the coupled connecting device 1 and in its end position projects under the slide 15 of the panic protection device. The place number plate 19 is secured in that the slide 15 is pushed over the L-shaped extension 20 .

The described and illustrated connecting device 1 (row connection) for row chairs 1 or armchair is a so-called "pull-out RV" or "sliding RV", of which all parts, namely the linking elements 3 , 4 , the stops 10 (clips) and the Slider 5 (red) are made of unbreakable plastic.
