Description

e Telescopic system for a closet, preferably pantry. The

  The present invention relates to a telescopic system for a closet provided with a body of furniture, including pantry,

  having at least one extensible part which slides

  retracted position and a pulled position, as well as a displacement system at least connecting the extended portion

to the furniture body.

  In known devices of this type, the system of

  Cement is behind the extensible part, in the extraction direction So that this system can still be housed behind the retractable extensible part, it is necessary to provide a relatively large space between the adjacent rear partitions of the extensible part and the furniture body This space is a loss in useful storage space, the closet can only receive boxes

  or bins, constituting this storage area, of

relatively low level.

  The present invention aims to create a telescopic system of this type, the displacement system occupies a reduced space, space imposed by the size of the cabinet can be used almost completely.

as a useful storage area.

  According to the invention, the extensible portion has for the displacement system at least one housing, lateral to

  the latter in the sense of displacement.

  The displacement system according to the present invention being lateral to the extensible part, the latter can have a depth that allows it to reach the partition

  back of the furniture body in the closed position

  total weight of the furniture body can therefore be used

  space, the capacity of the closet can be considered

  badly increased, without increasing its dimensions.

  The thickness of the displacement system is generally minimal, the lateral disposition of this system does not lose

  only a negligible part of the usable area.

  Other features of the present invention are

  data in the claims, the description and the

attached drawings.

  The invention will be described in more detail with the aid of an exemplary construction illustrated in the drawings, which represent: FIG. 1: a perspective view in partial section of a telescopic system according to the invention, provided on a pantry and pulled out of a cabinet;

  of a telescopic system conforming to the

  vention, in extraction position; Figure 10: a lower end of a pivoting arm of the displacement system, connected to a rear vertical upright of the expandable portion and seen in the direction of the arrow X of Figure 9; Figure 11: a section along the line XI-XI of Figure 10; Figure 12: a section along the line XII-XII of Figure 10. Figure 1 shows a portion of a furniture body 1 of a pantry, with an extensible portion constituted by a frame 2, sliding along 'a side wall

3 of the furniture body.

  The frame 2 consists of two lower and upper guide bars 4 and 5, as well as two vertical uprights

  front and back 6 and 7 connecting the two bars.

  The guide bars 4 and 5 have a tubular shape and a rectangular section, the vertical upright 6 having a U-shaped profile and being open towards the front in the extraction direction P The vertical upright 7 has an angled profile with a section in approximately Z. The front ends 8 and 9, in the extraction direction P, of the guide bars 4 and 5 constitute openings 10

  (Figure 8), in which are embedded arms corresponding to

  weights 11 of lower and upper transverse supports 12 and 13 of the same shape (FIGS. 1 and 8). The door supports 12 and 13 are L-shaped. The arm 11, which is one of the sides, is plate-shaped and is shorter than the second side 14, 15, which has

  a U-shaped profile and makes it possible to fix a closet door 16.

  This attachment arm 14, 15 extends substantially over the entire width of the door, which rests on the entire surface of the transverse bottom 17, 18 of the same arm On their inner faces 19 and 20, opposite to the side wall 3 of the furniture, and on their front ends 8 and 9, the guide bars 4 and 5 have a recess 21 open on the edge (Figure 8), in which are embedded the branches 22 and 23 of the attachment arms 14 and 15 of the supports of door 12 and 13 In this recessed position, the funds 17 and

  18 supports 12 and 13 constitute, along with the longitudinal edges

  free tudinal 24 and 25 of the upright before 6, a

  common support surface for the closet door 16,

  the latter to have support and alignment

  perfectly in relation to the frame, over its entire length.

  As shown also in Figure 8, each arm

  11 of the door supports 12 and 13 has two holes

  extreme, and another located approximately mid-way

  arm length, 26 to 28 The end threaded holes 26 and 27 having preassembled screws 29 and 30 serving as adjustment pieces, these are attached to the arms 11 before they fit into the corresponding guide bars 4 The supports 12, 13 to which the door 16 is fixed, screwed preferably, are embedded in the bars 4, 5, in the direction of the arrow 31 On their inner face 20, the bars 4 and 5 have, at screws 29 and 30 in mounting position, openings 29a

  a, in which it is possible to drive a rotator

  screws and whose diameter is smaller than that of the screw heads, the free ends of the screw rods 29 and 30 are

  adjacent to the opposite inner face of the guide bar.

  When the screws 29 and 30 are rotated, the arm 11 of the door supports 12, 13 is moved in the bars 4 and 5 through the threaded holes 26 and 27. If the screws 29 and 30 rotate in the same way , the cupboard door is moved in translation transversely to the plane of the frame 2 If these two screws 29 and 30 turn differently, the door 16 pivots about an axis parallel to the uprights

  6 and 7 The screws 29 and 30 thus allow a

  gating of the door 16 in two directions relative

to the frame.

  Another screw 32 is screwed with an intermediate washer 33 into the central threaded hole 28. The internal face 20 of each of the two guide bars 4 and 5 is provided with an opening 34 for the screw 32. The diameter of this opening is greater than The screw 32, as well as the transverse support 12, 13 and the door 16 which is fixed thereto, can thus be moved, with respect to this opening 34, parallel to the plane of the frame 2, so that

  in the vertical direction than in the horizontal direction

  tale The screws 29, 30 and 32 thus allowing a displacement

  simple and fast door in four different directions

  rents, the latter can be exactly aligned by

  relative to frame 2 and cabinet 1.

  In addition to the transverse supports 12 and 13, other fasteners 36 of the same shape are provided for the door

  16, one of these parts being shown in Figure 8.

  They consist of approximately L-shaped bent elements, having a relatively narrow and longer attachment side 37, and a wider and shorter recessed side 38. The fixing side 37 is provided with two horizontal elongate holes 39 and 40 , on both sides of the recessed side 38 The elongate holes 39 and 40 allow the door 16 to be moved in translation and to align with the frame 2 The attachment sides 37 of the parts 36 extend vertically in the mounted position and rest by their entire surface on an inner face 41 of the door. The recessed sides 38 penetrate into a U-shaped opening 42 of the vertical upright 6 The recessed side 38 has approximately at its center an elongated hole 43 extending in the vertical direction and allowing an orientation in the same direction of the fasteners

  36 and / or the door 16 with respect to the frame 2.

  The flush-mounted sides 38 of the fasteners 36 receive

  a U-shaped clamping piece 44 made of sheet metal

  The first side 45 of the clamping piece 44 has an opening 46, the other side (not shown) having a threaded hole for a stationary element.

  fastening represented by a screw 47 The diameter of the

  turn 46 corresponds to the width of the elongate hole 43 and is flush with the latter when the clamping piece 44

  is nested Another elongate hole 48, extending

  the vertical wall 6 opposite the side wall 3 of the cabinet is associated with the elongate hole 43 and the opening 46. The vertical elongated hole 43 aligns the fixing piece 36 and the door 16 in the vertical direction relative to the frame 2 The horizontal elongated hole 48 of the vertical upright 6 further makes it possible to move and adjust perpendicularly to the frame 2 the fasteners 36 and the clamping elements

  nested 44, as well as the closet door 16.

  The bottom 50 of the transverse profile (FIG. 8) of the vertical upright 6 has two openings 51 and 52 superimposed

  and separated by a distance equal to that of the allon-

  39 and 40 on the attachment side 37 of the part 36

  openings allow you to insert a tool,

  252829 i férence, to ensure the attachment of the piece 36 on the face

  41 of the door, using screws or other

  the elongated holes 39 and 40 on the attachment side 37.

  The fasteners 36 being housed in the U-shaped section of the vertical upright 6, they can be fixed directly near the longitudinal edge 53 of the door 16, adjacent to the side wall 3 This possibility is particularly advantageous for closet doors which have only their normal thickness at the edge and the remaining part is so thin that it would be impossible

to fix screws.

  The transverse supports 12 and 13 and the fixing pieces

  36 allowing a very precise alignment of the door 16 relative to the frame 2 and the furniture body 1, the same door 16 ensures a perfect seal on the face

  front of the cabinet, when the pantry is closed.

  Baskets 54, trays or others, constituting storage surfaces, can be hooked to the frame 2 to receive provisions The baskets 54 have hooks (not shown), fixed in elongated openings 55 and 56 (FIGS. 1, 2 and 8). These openings are arranged with the same spacing and aligned one behind the other in the sides 54 of the vertical upright 6 and in a longitudinal flap 57 of the vertical upright 7 The openings 55 and 56 extending in the vertical direction 6 and 7 uprights, the hooks can be removed from the corresponding openings by lifting the baskets These hooks only slightly protruding from the outer face of the longitudinal flap 57 facing the side wall of the furniture, they are not on the path of other screwing elements, fixed in particular in a displacement system 58 for the frame 2, which

  will be described in more detail below.

  The upper and lower guide bars 4 and 5 allow

  guide the frame 2 along the side wall 3 of the furniture in two guiding devices 59 to 61 upper and lower, represented by roller guides The two guiding devices can also be constituted by a slideway, having for example

interlocking T-profiles.

  The upper guiding device 61, fixed to the side wall 3 of the cabinet, consists of a housing 62 with a U-shaped opening 63, in which at least one roller 64 is housed.

  The upper guide bar 5 is engaged in the opening

  63 and its upper edge 65 carries the rollers 64, which ensures a stable guide and a free movement of the

  frame relative to the furniture body.

  The lower guide device 59, 60 consists of two rollers, whose diameter and spacing in the direction of travel are slightly greater respectively and

  more important than pebbles 64.

  The front roller 59, in the extraction direction P, is located in the lower front corner of the side wall 3 of the furniture, the other roller 60 being provided behind the roller 59 with a spacing which corresponds approximately to a quarter of the width of the side wall 3 The two rollers 59 and, arranged above a floor 66 of the furniture body

  1, at equal height and at a short distance from this same plane.

  expensive, are mounted on a support 67 in the form of a rod.

  To ensure the positioning of the frame 2 on the lower guide device 59, 60, the lower guide bar 4 has a U-section insert rail 68 (FIGS.

  3 and 4), provided on the lower edge 69 of this same bar 4.

  The sides of the rail 68, facing the floor 66, enclose

  sideways rollers 59 and 60 on their upper edge,

  thus ensuring the required stability.

  The support 67 is constituted by an elongated rectangular plate, the lower edge 70 of which is chamfered on its front part, in the extraction direction P. The chamfered edge 71 and the corresponding front edge 72 of the support 67 coincide with the lower corner The remainder of the longitudinal edge 70 and the opposite upper longitudinal edge 73 forming an acute angle with a lower edge 74 of the lateral partition 3, the support 67 has an oblique orientation upwards and towards the before, in the direction of closure of the frame 2 The support 67 extending over the entire width of the side wall 3, the support is perfect and ensured on a large

area.

  The rear vertical upright 7 is constituted by an angled rail having approximately a Z-shaped section (FIGS. 3 and 5), the longitudinal shutter 57 connecting two lateral wings 76 and 77 of the upright 7, one of which is wider.

  and the other narrower The longitudinal flap 57 is parallel to

  to the side wall 3 of the cabinet, the side profile 77

  extending over the profile 57, up to the proximal

  A housing 78 (FIGS. 3 and 4) for the displacement system 58 is thus formed between the lateral partition 3 and the longitudinal shutter 57. The external face of this shutter 57, opposite to the lateral wall 3 of the furniture. , is in the same plane as the corresponding outer faces of the guide bars 4 and 5 and the vertical upright 6, which form the inner face of the frame In the extraction direction, the narrowest lateral wing 77 of the upright vertical rear 7 is in front of the wing

  the widest lateral 76, which is also directed

  perpendicular to the side wall 3, but in the opposite direction to that of the narrow wing 77 The outer rear face 80, in the extraction direction P, of the widest side wing 76 forms an abutment surface, by which -10

  The frame 2 is connected to the furniture body by means of a displacement system 58 This system is constituted by an articulated frame, composed of two pivoting arms 81 and 82, the second of which is approximately twice

  less long than the first The longest arm 81

  cule at its lower end 83 on the support 67, near the upper longitudinal edge 73 and the rear edge 75 of the same support The lower end 84 of the shorter arm 82 is articulated to the lower part of the face of the longitudinal flap 57 facing the side wall 3 of the cabinet An upper end 85 (Figure 3) of the arm

  the longest 81 is slidably mounted by an element of

  semblage 86 and a safety element 87 (FIG. 7), in an upper support element 88, fixed to the vertical upright

back 7.

  At mid-length about the longest arm 81, one end

  upper 89 of the shorter arm 82 is articulated by the

  intermediate of two fishplates 90, 90 'applied on opposite sides of the pivoting arm 81 (Figure 4) The fishplates have an approximately triangular outline and are fixed by zones of opposite angles to each other, rigidly to the upper end 89 of the shorter arm and pivotally to the longer arm 81 These ribs have the form of thin plates, they do not substantially protrude from the pivot arms-81 and 82, which are also relatively narrow Due to the narrow shape of the pivoting arms and the splints, the housing 78, in which these elements are placed when the frame 2 is fitted, can also be very narrow, so that the useful internal space of the furniture body is less than the free width of the same body 1 that approximately the only width of the pivoting arms 81 or 82 The use of the internal volume is optimized, especially as the

252 E 291

  depth of the frame 2 and / or baskets attached thereto 54 may be equal to the maximum depth of the furniture body. The narrow housing 78 also receives the upper support element 88, consisting of an approximately rectangular and relatively thin plate 91, with small rounded sides. The plate 91 has a central rectangular slot 92, surrounded and shaped, in the direction of its length. limited by a rim 93 which protrudes on one side of the plate On the lower and upper ends 94 and 95 of the slot 92, the flange 93 has a partially circular shape, the radius of curvature of which corresponds to the free width of the slot 92 Between these ends, the flange 93 has parallel sections partially overlapping the slot

  92, so that these sections constitute

  slit for the passage of an assembly member 86, whose free width is smaller than the diameter of the

  ends 94 and 95 and to the free width of the longitudinal slot

  The free width of the slot 96 corresponds to the diameter of the connecting element 86, constituted by a trunnion and fixed to the upper end of the pivoting arm.

  On the other hand, the diameter of the upper end 95 of the slot 92 corresponds to that of the washer-shaped safety element 87, which is screwed onto a free end of the connecting element 86. the end

  upper part of the upper support element 88 makes it possible

the slot 96.

  The length of the rectilinear section of the flange 93 is such that the security element can not reach the zone of the upper end 95, during the translations of the frame

framework 2.

  The lower end 94 of the slot forms with the corresponding section of the flange 93 a cavity, in which is housed a buffer 97, of flexible rubber preferably This buffer, which has a rectangular profile, can not unexpectedly exit the cavity as a result The buffer 97 prevents the assembly and safety elements from striking the lower end of the longitudinal slot 92 of the support 88, when the frame

2 is fired.

  The outer face 98 of the upper support element 88, oppo-

  At the edge 93 (FIG. 7), the full surface rests on the longitudinal flap 57, to which the same support 88 is fixed by means of screws 99. The support element 88, preferably of plastic, is relatively light. It is fixed in

  the upper quarter of the rear vertical pillar 7, to a certain

  distance from the free end 100 of the latter (

  5), so that its longitudinal edge 101 is directly adjacent to the lateral wing 77 (FIG. 6). With respect to the widest lateral wing 76, there remains a gap that corresponds approximately to the width of the upper support element and leaves enough room

  to provide the hooking holes 56 of the baskets 54.

  In the recessed position (FIG. 2), the lateral flange 76 of the rear vertical upright 7 bears on the rear wall of the cabinet. Moreover, the pivoting arms 81 and 82 are

  located one behind the other and close together; in this posi-

  The upper end 89 of the shorter arm 82 bears on the adjacent longitudinal edge of the longer arm 81. The pivot arm 82 is substantially vertical, the arm 81 forming a very small angle with a vertical plane.

  In fact, the lower extremity 83

  arm 81 is preassembled to the support 67, and the pivot arm

  82 is connected to the arm 81 via the ribs, 90 'The two arms 81 and 82 and the support 67 form a complete subassembly, which is fixed to the side wall 3 of the furnished through the support 67 This subassembly furthermore comprises the lower guide device 59. Before the assembly of the cupboard, all the elements required for the extraction movement are therefore exactly oriented relative to one another in their mutual position, which considerably facilitates the editing and excludes errors. The difference between the telescopic system shown in FIGS. 9 to 12 and the previously described construction form lies solely in the fact that a housing 78 has

  receives an additional displacement element 110, constituting

  killed by a lever bent and allowing the extensible portion 2 has to tilt forwards or backwards relative to the lower guide device 59a, 60a of the furniture body, in the direction of extraction P. The Lever 110, pivoting, is fixed to the lower part of the longitudinal flap 57a of the vertical upright 7a using a pivot 111, preferably on a cavity 112 oriented

  in the direction of the support 67a (FIGS. 10 and 12).

  In the bent portion of lever 110, the shorter arm

  82 a of the displacement system 58 a is fixed by means of a sec-

  This latter has a rod 114 which penetrates into a corresponding opening of the arm 82. A ring 115, located in corresponding openings of the lever 110,

  is mounted on the rod 114 (Figure 12).

  For the passage of the pivot 114 in the vertical upright 7 a,

  the latter has an elongate hole 116 extending vertically

  The thrust washer is in contact with its edge, outside the elongate hole 116, with the face, and is traversed by a pin 117, the axial position of which is provided by a stop washer 118 (FIGS. of

  the cavity 112 opposite the support 67 a.

  Lever 110 consists of two geometrically bent halves

  Equally equal, one over the other at the ends of the 29 arms of the lever, but separated in the area of the elbow by a spacing corresponding approximately to the length

axial of the ring 115.

  To pivot lever 110 there is provided a set screw 119, held in a corresponding threaded hole of

  the free end 120 of the lever arm 121 the longest.

  The inner face of the head 122 of this screw rests on the edge of a slot 123, provided in the lateral wing 77 at the

  narrower vertical upright 7a (Figure 10).

  To ensure the position of the lever 110 in rotation is preferably provided a second screw 124 also fixed in a corresponding threaded hole of the longer arm 121 This screw is located below the adjusting screw 119, at a short distance of the latter, and the external face of its head 125 bears on the internal face of the lateral wing 77 a

  the narrowest or on the edge of the slit 123.

  The displacement system being fixed to the furniture body with the support 67a and the rollers 59a, 60a, with which it forms

  a subset, it is very difficult to modify later

  its position relative to the extensible part 2a, if it proves during assembly, for example, that the rails 68a of this part 2a do not simultaneously bear on the

  two rollers of the guide device.

  In order to quickly and easily compensate for such manufacturing or mounting deviations, the extensible portion 2 can pivot relative to the support 67a and / or the furniture body. By turning the adjustment screw 119, it is possible to rotate the lever 110, from each of its positions and in a clockwise or

  opposite direction, about its axis formed by the pivot 111, jus-

  that the rail 68 has the extensible portion 2a is based on the two rollers 59a and 60a When the lever 110 pivots, the shortest pivot arm 82a is raised or lowered through the pivot 113 Through the splint, the arm 82 has thus exerted on the arm 8 Ma a force that pivots the latter around its point of articulation with the support 67 has the end of the arm 81 has then pivoting the upright 7a As soon as this amount Ya and the expandable portion 2a occupy the desired position, the lower screw 124 is tightened and / or loosened in the corresponding hole of the longer lever arm 121, until its head 125 bears on the inner face of the narrow side wing 77a of the vertical upright 7a The head 122 of the adjusting screw 119 simultaneously bearing on this wing 77a, the lever 110 can no longer pivot The position
