FR2586747A1 - FOLDING DOORS WITH TWO LEAVES - Google Patents

Abstract

1. A device for closing folding doors with two folding panels, of the kind comprising a guide rail (9) mounted in the upper jamb crossbeam (1) in which a guide (8) integral with the sliding panel (4) can slide, characterized in that the guide finger (8) ends a slide bar (7) to the longitudinal axis XX' of which it is perpendicular, this slide bar (7) being mounted on a horizontal holder (6) fastened to the upper part of the inner side of the sliding panel (4) close to its edge.

Description

1 2'586747

  The present invention relates to a device for

  both an improvement in the final phase of closure of

  folding doors with two leaves or two double leaves useful

  more generally for closing built-in cupboards.

  According to one of its preferred applications, but

  non-limiting, it aims at a system allowing to apply par-

  completely around the leaves on the door frame, eliminating any play and interlocking. Said system provides

  plus an aesthetic effect with the doors closed if you wish to conceal-

the jamb.

  Of all the mechanisms known to allow the folding

  ge of the leaves, these use at least one guide rail fixed in the upper part of the frame and in which slides a finger or sometimes a small roller fixed at the end

  upper part of the free part of the second leaf ensuring the closing

  meture. The configuration of the rail is made in such a way that the rail-finger or roller combination keeps the closing leaf suspended, relieving the connection hinges of the two leaves.

  and the hinges between the doorframe and the first leaf.

  All these closures using this system require a certain clearance between the upper part of the leaves, the rail of

  guide and frame to get a good functioning.

  If the invention retains the principle of the guide rail

  ge and positioning finger of the second leaf to allow the door to be opened or closed, it is characterized by

  that the support of the guide finger is mounted on a slide.

  The present invention will be better understood by the des-

  following description and the attached figures:

  - Figure I shows the door fully open -

  te, the two leaves folded over each other; - Figure 2 shows the door completely closed from the doorframe; - Figure 3 shows a perspective view of the

sliding finger.

  Figure 1 shows the door fully open with its fixed part (1) or jamb in which were screwed plugs (2) or hinges also screwed into the first leaf (3) allowing the pivoting thereof relative to the

door frame (1).

  On this first leaf (3) and opposite the cards (2),

2 2586747

  a hinge (5) is screwed to it and allows to connect the first

  leaf (3) to the second leaf (4) offering the possibility of a

angular beat of 180.

  Opposite this hinge (5), the second leaf (4) is provided, in its upper part, with a support (6) fixed on its internal face. The internal part of said support consists of a slide receiving the slide (7), the end of which forms a

  finger (8) perpendicular to its longitudinal axis XX '.

  The finger (8) engages in the slide (9) fixed

  in the upper part of the doorframe.

  The evolution of the door being closed or

  like all doors based on this system

  teme. It is only at the end of the closing stroke that the sliding finger device which is the subject of the present invention will allow the second leaf (4) to come to superimpose and join the vertical upright of the jamb (10) according to the representation given by the

  Figure 2 o the slide (9) of the frame has not been shown.

  Figure 3 shows more particularly the

sliding finger device.

  Consisting of a body or support (6) of parallel shape

  the hollow elepiped forming a four-sided slide, pre-

  metal or hard material. It receives a slide (7)

  also of parallelepipedal section in its guiding part

  also made of metal or hard material. The free end ends with a cylindrical finger (8) perpendicular to the longitudinal axis XX 'of the slide (7). In contrast, the slide is

  ends with a rod (11) receiving a helical spring of com

  pressure (12) which tends to push the slide (7) outwards

  laughing but to limit its travel, a cylindrical pin (13) passed through the rod (11) abuts on the face

back of the body or support (6).

  To allow the fixing of the body or support (6)

  arrangements have been made on the side faces, in part

  particular two holes (14) for screw passage and two lights (15)

  to engage the tip of a screwdriver.

  Compared with known systems, the invention pre-

  feels the following great advantages: 1 - very easy and fast installation by simple screwing: no notch, and complete opening by removal, without tool,

  of the pin allowing access without any discomfort for landscaping-

3 2586747

  possible inside the cupboard, for example shelving

full.

  2 - up and down guidance option for good-

no door leaves.

  3 - the leaves being connected by a hinge whose axis is offset inwards relative to the spring, ensures

  effective closing by pinching the leaves between frames.

Claims (2)

CLAIMS.   1. Door with two or two foldable foldable leaves   more generally used to close the character cupboards   sée in that the extreme leaf (s) are provided with sliding guide fingers whose stroke is variable depending on the opening or closing position of said door. 2. Door according to claim 1 characterized in that   that the leaves can partially or completely cover -   ment and join the jambs, bringing an effect   aesthetic to the whole and a perfect closure.
