Description

"Panel, in particular for cupboard door, and in particular for door

  The present invention relates generally to panels formed by a plate surrounded by a frame at its periphery. It relates more particularly, but not necessarily exclusively, to the case where such a panel is used for the constitution of a door, in particular a door for a cabinet, and in particular a door for an electrical cabinet, whether it constitutes such a door alone or

is only one of the leaves.

  This is the case for example when, to leave at least part of the contents of the cabinet concerned, the

  plate that includes such a panel is glazing.

  It is known, moreover, for the constitution of light boxes, to which the present invention can also find its application, to similarly hold a plate at its periphery by a frame, including at least one of the sides, and in practice, each of these comprises, on the one hand, a section of profile, which has a supporting facet longitudinally to buttress the plate, and, on the other hand, a glazing bead, which is hooked and snapped onto this section of profile for the application of

plate against its support facet.

  This is the case, for example, in the British patent

No 1 602 730.

  But, in practice, in this British patent, the attachment is made so as to allow mounting

  pivoting of the glazing bead on the profile section.

  This attachment therefore necessarily takes place at a distance from the support facet of the section of section, and, jointly, the latching necessarily occurs between

  this facet of support and attachment.

  As a result, the force exerted by the glazing bead on the plate is relatively poorly controlled, and the maintenance of

  this plate is therefore relatively poorly insured.

  The present invention generally relates to a provision which, apart from any pivoting assembly, is advantageously free from these drawbacks and

  on the contrary allows an effective and safe maintenance of the plate.

  More specifically, it relates to a panel, in particular a panel for a cabinet door, and in particular for an electrical cabinet door, of the type comprising, to hold a plate at its periphery, a frame, at least one of which on the sides comprises, on the one hand, a section of profile, which longitudinally has a support facet for abutting the plate, and, on the other hand, a glazing bead, which is hooked and snapped onto the section of profile for the application of the plate against its support facet, this panel being generally characterized in that, jointly, on the one hand, the profile section has, in the vicinity of its support facet, projecting from to this support facet in a direction perpendicular thereto, a hooking return, which extends on the side of this support facet, and with which the glazing bead is itself engaged by a return of hooking directed in the opposite direction, and, on the other hand, the profile section has, at a distance from its support facet, a latching shoulder, which, in a direction parallel to this support facet, extends on the other side of its hooking return relative to to this facet of support, and with which the glazing bead is itself engaged by a

  latching shoulder directed in the opposite direction.

  Thus, the force exerted by the glazing bead on the plate to be maintained is counteracted as closely as possible by the hooking return of the section of profile, along one of the edges of this glazing bead, for the benefit of an effective and secure maintenance. of

the plaque.

  At the same time, the snap-fitting occurs at a distance from this attachment, along the other of the edges of the glazing bead, and, taking into account the lever arms in play, the effort to be developed to ensure this snap-fitting remains advantageously

  moderate without affecting its effectiveness.

  In other words, while being easy to set up,

  the glazing bead according to the invention is advantageously effective.

  The characteristics and advantages of the invention

  will emerge from the description which follows,

  by way of example, with reference to the appended schematic drawings in which: FIG. 1 is, with a local cutaway, a perspective view of a panel according to the invention shown in place on a cabinet body; Figures 2 and 3 are, on a larger scale, cross-sectional views of this panel, each along lines II-II and III-III of Figure 1 respectively, with the initiation of the corresponding sections of the cabinet body concerned ; Figure 4 is, on the scale of Figures 2 and 3, a cross-sectional view of one of the sections of profiles used for the construction of the frame that includes this panel; Figure 5 is, on the scale of Figure 4, a cross sectional view of one of the corresponding glazing beads, along the cross section of Figure 2; Figure 6 is, on the same scale, a cross sectional view of the other of the corresponding glazing beads, along the cross section of Figure 3; Figures 7 A, 7 B are cross-sectional views which, similar to those of Figures 4 and 5, illustrate two successive phases of the construction of the panel according to the invention; Figures 8, 9 and 10 are cross-sectional views which, similar, each respectively to those of Figures 4, 5 and 6, relate to an alternative embodiment. These figures illustrate, by way of example, the application of the invention to a cabinet 10, and, for example,

to an electrical cabinet.

  In a manner known per se, this cabinet 10 comprises a body 11, and, articulated at the front of this body 11 to constitute

a door, a panel 12.

  The corresponding provisions not falling under the

  present invention, they will not be described here.

  In a manner also known per se, the panel 12 is formed of a plate 13, for example a glazing, with, disposed at the periphery of this plate 13, to ensure its maintenance

  and the articulation to the body 11, a frame 14.

  Either 14 A the vertical sides, or uprights, of this frame

  14, and 14 B its horizontal sides, or crosspieces.

  At least one of the sides 14 A, 14 B of the frame 14, and, in practice, each of these, comprises, on the one hand, a section of profile 16, which has, longitudinally, a support facet 18 to buttress the plate 13, and, on the other hand, a glazing bead 20 A or 20 B, which is hooked and snapped onto the section of section 16 for the application of the plate 13 against

the support facet 18 thereof.

  In the embodiments shown, a seal 21 is inserted between the plate 13 and each of the profile sections 16, and, similarly, a seal 22 is inserted between this plate 13 and each of the glazing beads 20 A ,

20 B.

  For example, these seals 21, 22 are

  integral with the plate 13, for example by gluing.

  According to the invention, the profile section 16 has, in the vicinity of its support facet 18, which is planar, projecting relative to this support facet 18 in a direction Dl perpendicular thereto, a return d 'hooking 24, which extends on the side of this support facet 18, and with which the glazing bead 20 A or 20 B is itself engaged by a hooking return 25 directed in the opposite direction to the direction in which extends the attachment return 24, and, jointly, the section of profile 16 also has, but at a distance from its support facet 18, a latching shoulder 26, which, in a direction D 2 parallel to its support facet 18 extends on the other side of its hooking return 24 relative to the latter, and with which the glazing bead 20 A or 20 B is itself engaged by a shoulder of snap 27 directed in the opposite direction to the next

  which extends the latching shoulder 26.

  In practice, in the embodiments shown, the support facet 18 of the section section 16 belongs to a plate 28 which extends transversely over the entire width of this section section 16. The support facet 18 s' more precisely extends along one of the edges of the plate 18, forming locally on

this one an extra thickness.

  The hooking return 24 extends substantially

  parallel to the support facet 18.

  It is offset relative to this support facet 18 both in the direction Dl perpendicular thereto and in

  the direction D 2 which is parallel to it.

  In practice, it is carried by a rib 30

  perpendicular to the support facet 18.

  In the embodiment more particularly shown in FIGS. 1 to 7, this rib 30 comes from a counter-plate 31, which, parallel to the plate 28, extending transversely over only a portion of the width of that here, formed with this plate 28, projecting from the side of the support facet 18, at the edge thereof, a

  volume in box 32, of rectangular cross section.

  The rib 30 extends recessed relative to the edge

  of this box volume 32 close to the support facet 18.

  The latching return 24 extends in overhang from the rib 30 which carries it, in the direction of the support facet 18, and parallel to it, but without

  extend beyond the outline of the volume in box 32.

  The latching shoulder 26 that comprises the section of section 16 also extends substantially parallel to

the support facet 18.

  It is offset with respect to this support facet 18 both in the direction D 2 parallel to it and in the

  direction Dl which is perpendicular to it.

  In practice, the latching shoulder 26 extends on the other side of the support facet 18 relative to the return

hanging 24.

  In other words, it extends on the other side of the plate 28 relative to the support facet 18, on the back of this plate 28. More specifically, in the embodiments shown, this latching shoulder 26 is formed by the edge of a wing 34 which the profile section 16 presents laterally, substantially perpendicular to its support facet 18, along the edge of its plate 28 opposite that of the

  along which this support facet 18 extends.

  This wing 34 extends to the back of the plate 28, in

  direction opposite to the support facet 18.

  In the embodiments shown, the profile section 16 has another wing 35, which, disposed along the edge of its plate 28 along which extends the support facet 18, extends like the previous one in the direction opposite

to this one.

  The height of this wing 35 is greater than that of

the previous wing 34.

  Finally, in the embodiments shown, the profile section 16 has, on the back of its plate 28, between its wings 34 and 35, and in the same direction as the latter,

a stiffening rib 36.

  At the same time, in the embodiments shown, the hooking return 25 that a glazing bead 20 A or 20 B comprises inwards, according to a transverse profile in the shape of a butt, this glazing bead 20 A or 20 B, the

along one of the edges of it.

  The snap-on shoulder 27 which a beadwork 20 A or 20 B jointly presents extends substantially

  parallel to its attachment return 25.

  As for the section of section 16, this latching shoulder 27 is offset with respect to this latching return 25, in both directions Dl, D 2. In practice, the latching shoulder 27 and the hooking return 25 extend in opposite directions, one by

compared to each other.

  In the embodiments shown, the snap-on shoulder 27 belongs to a rib 37 which extends projecting from the internal face of the glazing bead 20 A or B. The catch return 25 therefore extends in a first direction, in the direction D 2, and the rib 37 to which the latching shoulder 27 belongs extends in the direction

  reverse, in a direction opposite to direction D 2.

  In the embodiment more particularly shown in FIGS. 1 to 7, the glazing bead 20 A or 20 B has an extension 38 perpendicular to its hooking return 25 beyond the rib 37 carrying its shoulder

27.

  In addition, in this embodiment, this rib 37 forms at its root a thickening 40 which delimits

the latching shoulder 27.

  Finally, in the embodiments shown, the glazing bead 20 A or 20 B has, longitudinally, from place to place, projecting from its internal face, between its latching return 25 and its latching shoulder 27, ribs of stiffening 41 by the edge of which it

  relates to the section of profile 16.

  Globally, glazing beads 20 A and 20 B are similar.

  They generally have a transverse angle profile, with their hooking return 25 parallel to a first wing 42 and their snap shoulder 27 perpendicular to a

second wing 43.

  In the embodiment more particularly shown in Figures 1 to 7, only the wing 42 has

  stiffening ribs 41 on its internal face.

  As a glazing bead 20 A on a vertical side 14 A of the frame 14, the angle formed by the two wings 42, 43 is largely cut down, first by a chamfer 44 then by a

round 45, figure 5.

  Therefore, the stiffening ribs 41 that projecting from the inner face of its wing 42 this

  glazing beads 20 A are of unequal heights.

  As a glazing bead 2 OB on a horizontal side 14 B of the frame 14, the angle formed by the wings 42 and 43 is straightforward, these wings 42, 43 joining one another along an edge

46, figure 6.

  Anyway, the glazing beads 20 A and 20 B are both in the form of profile sections. While the profile section 16 is preferably made of metal, these glazing beads 20 A and 20 B are

  preferably in synthetic material.

  For the constitution of a panel 12 according to the invention, it is first proceeded to the assembly of the various sections of profile 16 necessary for the constitution of the frame 14, after cutting, to the correct length, and according to a

  miter cut of these sections of profile 16.

  For example, and as shown in FIGS. 1 to 7, this assembly can be done using brackets 48, the two wings 49 of which are each respectively fitted into the boxed volumes 32 of two sections of profile 16 to

to assemble.

  If desired, these brackets 48 are joined to the profile sections 16 which they assemble, at

  using for example screws not shown.

  It is then proceeded to the establishment of the plate 13, Figure 7 A, after the seals 21 and 22 have been reported there It is finally proceeded to the establishment of the glazing beads A and 20 B. S ' acting, for example, on a glazing bead 20 A, this glazing bead 20 A is first presented at an angle with respect to the section of section 16 to which it must be attached, FIG. 7B, then, after its straightening, it is proceeded at the insertion of its latching return 25 behind the latching return 24 of this section of section 16, until, this latching return 25 coming into contact with the rib 30 carrying the latching return 24 of the section of section 16, FIG. 2, its latching shoulder 27 can be hooked

  on the latching shoulder 26 of this section of section 16.

  The seals 21, 22 are then slightly compressed, and the hooking returns 25 and 24 of the glazing bead A and of the profile section 16 are thus jointly under a slight prestress. As will be noted, the glazing bead 20 A carries, by the very back of its hooking return 25 on the plate 13, by means of the seal 22, which ensures a

  particularly firm and secure hold of this plate 13.

  For the installation of glazing beads 20 B, the following procedure is followed:

in the same way.

  In the variant embodiment shown in FIG. 10, the rib 30 of the section section 16 carrying its hooking return 24 is directly derived from the plate 28 of this section section 16, no volume in the box being

provided on it.

  Jointly, in this alternative embodiment, between this nevure 30 and the support facet 18, the section of section 16 has, projecting, at the edge of the support facet 18, for delimitation thereof, another rib , which, of lesser height than that of the rib 30, remains sufficiently distant from the attachment return 24 to allow insertion between it and the return

  attachment 25 of the associated glazing bead 20 A or 20 B.

  Finally, in this alternative embodiment, the wing 34 of the section of section 16, the edge of which forms the latching shoulder 26 has a height that is large enough that the associated glazing beads 20 A or 20 B can also find support there. through a stiffening rib 41

  then provided for this purpose on their wing 43, FIGS. 9 and 10.

  Furthermore, in the embodiment shown in these Figures 9 and 10, the glazing beads 20 A and 20 B have no extension beyond the rib 37 to which their latching shoulder 27 belongs, this rib 37 s 'extending

  protruding inwards along their corresponding edge.

  Furthermore, in this alternative embodiment, it is not

  expected no thickening at the root of this rib 37.

  For the rest, the provisions are of the same type as

those previously described.

  Of course, the present invention is not limited moreover to the embodiments described and shown, but encompasses any variant of execution and / or

  combination of their various elements.

  In addition, the field of application of the invention is not limited to that of electrical cabinets alone, or even that of cabinets alone, but on the contrary extends to that of any possible use of the panels of the kind

  concerned, for example in building or decoration.
