Definitions

  • the invention relates, first of all, to a panel of heat-sealable plastic material, which can serve in particular as a shutter or door element, comprising a frame made up of rectilinear elements providing a recess, at least partially filled with blades, also rectilinear, extending between two opposite parallel elements of the frame, the assembling members of the two opposite elements of the frame and the blades being constituted by a first rectilinear tongue rigidly associated with each element, projecting from the internal field thereof and engaging in grooves made in the end faces of the blades transversely to them.
  • the invention also relates to the method of assembling the blades and elements of such a panel as well as the machine used for the implementation of this method.
  • Panels of heat-sealable plastic are already known comprising a frame and filling blades, which can serve in particular as a shutter or door elements.
  • a known panel comprises a frame comprising two vertical uprights rigidly joined together by two horizontal and parallel crosspieces and, on the other hand, horizontal filling blades assembled to the vertical uprights of the frame by mechanical assembly members of the tenon type and mortise.
  • each filling blade is provided, at its two free end parts, with a vertical groove or projection cooperating with a corresponding vertical projection or groove in the amount of the frame (see FR - A - 2.293.568).
  • louver door of the same general type as mentioned above, the assembly members of the blades and the vertical uprights comprising an intermediate insert rigidly secured to each upright provided with a single small longitudinal rib shifted towards one of the wings of the insert coming to lock in a notch provided initially in the end of the blades.
  • the panel as described in FR - A - 2 040 047 does not allow a sufficiently rigid assembly of the blades with the uprights.
  • the object of the invention is to overcome the drawbacks mentioned above.
  • the solution to this problem consists in producing a panel according to FR-A-2040047 wherein said connecting elements of the two elements of the framework and further at least one blade ⁇ econde like tongue to the first cooperating with at least one second groove in the same way as the tongue with the groove and that the tongues are rigidly associated with each of the corresponding grooves by welding the material to ensure the assembly of the blades with the elements.
  • the blades may fill the entire recess of the frame, thereby making it completely closed.
  • this assembly is at the same time very simple to carry out and makes it possible to obtain a panel having a high resistance, therefore not liable to be deformed in use.
  • the invention makes it possible to produce a panel having a tear resistance which can reach and even exceed 30 kg on average per panel.
  • the blades can have any desired shape in cross section. They can either be separated from one another, thus leaving variable days between them, or on the contrary, contiguous, ensuring a perfect closure of the recess of the frame.
  • the panels assembled according to the present invention having a high rigidity can be used in a versatile manner, not only as a shutter but also as a gate, cladding, etc.
  • the assembly according to the invention is such that it makes it possible in particular to avoid the false squaring which occurs with most of the other assembly means known to date.
  • the assembly according to the invention allows perfect reciprocal holding of the blades and the uprights. As a result, it is possible to conceive of a simplified manufacture of panels devoid of end crossmembers. This simplification is all the more important as the assembly of the uprights and crosspieces constituting the frame is of the tab type.
  • Figure 1 is a partial schematic view, in exploded perspective, of a panel provided with assembly means according to the invention
  • Figure 2 is a schematic partial view in section along the line II-II of Figure 1
  • Figure 3 is a partial schematic view, similar to Figure 2, of a second embodiment of the invention
  • Figure 4 is a schematic view, on a smaller scale, of the machine for implementing the assembly method according to the invention.
  • the assembly means according to the invention apply in particular and without limitation to panels of all kinds, made of heat-sealable plastic, in particular PVC.
  • This panel comprises, in known manner, a frame made up of rectilinear elements 1 forming the uprights and the crosspieces of the panel, assembled at a square, providing a recess filled entirely or only partially by blades 2, also rectilinear, extending between two parallel and opposite elements 1.
  • blades 2 when the blades 2 are horizontal, they extend between elements 1 have, in opposite transverse cross-section, if the blades 2 are vertical, they extending between two elements 1 forming horizontal and parallel crosspieces.
  • the elements 1 have, in cross-section, a generally rectangular or pseudo-rectangular shape defining an inner edge 3, preferably full, delimiting the edge of the recess limited by the frame.
  • the two edges 3 of two elements 1 parallel to each other face each other and are intended for assembly by welding with the end faces of the blades 2.
  • the blades 2 can have, in cross section, any desired shape depending in particular on a desired aesthetic appearance.
  • the length of the blades corresponds to the spacing between the edges 3 facing the two elements 1 with which they are rigidly associated.
  • the pitch of the blades can be arbitrary.
  • the blades can be either contiguous or, on the contrary, spaced apart, thus saving days.
  • the assembling elements 1 and blades 2, according to the invention, are located at each end of a blade 2 and on the element 1 associated with this end. Thereafter, reference will therefore be made to only one of the two ends of each blade, it being understood that the assembly members are symmetrically placed with regard to the other end.
  • the element 1 At the element 1 are rigidly associated at least two tabs 4 and 4 'projecting from the middle part of the inner edge 3, elongated in the lengthwise direction of the element 1 and, preferably, for reasons of symmetry which are not strictly necessary , parallel to the edges defined by the edge 3 and the faces of the ribs 5 and 6 of the element 1 and of the panel.
  • the tongues 4 are either in one piece with the element 1 proper, being produced during the manufacture of the latter, or, on the contrary, added. Instead of two tabs 4 and 4 ', a greater number of tabs can be provided.
  • the tongues 4 and 4 ' are either continuous, that is to say uninterrupted from one end to the other of the element 1, or, on the contrary, discontinuous and therefore comprising interruptions. The latter solution can be adopted in particular in the case of non-contiguous blades 2.
  • the tongues 4 and 4 ' are intended to engage in the grooves 7 and 7' which they cooperate for welding and this, in each of the blades 2, transversely, in each of its end faces turned towards an inner edge 3 .
  • the grooves 7 and 7 ' are not made in advance in each blade 2 but produced at the same time as the assembly of the panel by the tongues 4, penetrating into this blade 2 so that the 'rigid and inseparable association, jamb blade made by heat sealing is of excellent quality.
  • FIG. 3 is rigidly associated with the element 1 at least one secondary tab 8 and preferably two secondary tabs 8 projecting from the inner edge 3 and respectively extending the sides of the sides 5 and 6 of the frame, which ensures overlap of the blade junction 2 - element 1.
  • These secondary tabs 8 can also allow the maintenance of seals or the like.
  • the secondary tongues 8 can also be placed recessed on the sides of the frame to form decorative elements.
  • the visible face of a tongue 8 can be any, flat, rounded, etc., as required.
  • the assembly method according to the invention is as follows: first of all, the various blades 2 constituting a panel are placed in the final relative positions which they will occupy relative to the elements 1. They are then held in place by all appropriate means.
  • the tabs 4 and 4 ′ of a first element 1 situated on the same side of the panel are then heated, by any appropriate means and for the desirable duration. Simultaneously or successively, the coplanar ends of the corresponding blades 2 are heated, also for the time necessary.
  • the element 1 is brought towards the end of the blades 2 by pressing so that the tongues 4 and 4 ′ penetrate into the end faces of the blades 2, thus forming and constituting the grooves 7 and 7 ′ and this, until the inner edge 3 comes to lock against the end face of the blades 2.
  • the heating time of the tongues must be longer than that of the ends of the blades because the surface to be heated on the elements 1 is greater than that to be heated on the blades 2.
  • the machine for implementing the method comprises, in a more complex form, two heating rules 9 intended to be brought each into contact with an element 1 and with a blade end.
  • the heating rules 9 are placed supports 10 for holding and blocking a plurality of blades 2 in their longitudinal direction and in their perpendicular transverse direction.
  • Two carriages 11 are placed on either side of the heating rules 9, as illustrated in FIG. 4. These carriages 11 which are intended to receive the elements 1, have along their outer edge each a longitudinal blocking element 11a by which the element 1 can be blocked in its longitudinal direction.
  • the carriages 11 are mounted movable in the transverse direction of the element 1, that is to say longitudinally with respect to the blades 2 (the blades 2 being orthogonal to the uprights 1) by means of suitable sliding means 11 b.
  • the heating rules 9 are carried by support means 9a which allow on the one hand to move these rules 9 so that they can be applied to the blades 2 and on the other hand to retract them from the space between the carriages 11 and supports 10.
  • the elements 1 blocked by the blocking elements 1 1 can be brought into contact with the rules 9 to heat the tongues 4 and 4 'and also pressed against the ends of the blades 2, when the support means 9a are retracted.
  • the blades 2 are first placed so that they are in the position corresponding to their final position in the panel to be produced.
  • the supports 10 are used so that these blades are thus blocked.
  • two elements 1 are placed on the carriages 11 by blocking them using the means 11 a.
  • the heating rules 9 are implemented and in a first phase, the rules 9 are brought into contact with the tongues 4 and 4 ′ in order to heat them. In a second phase, the heating rules 9 are brought into contact with the ends of the blades 2.
  • the heating rules 9 are then retracted and the carriages 11 moved one towards the other so that the tongues 4 and 4 'associated elements 1 begin to approach the blades 2, then come into contact with the ends of the blades 2, then sink into them later by forming the grooves 7 and 7 '.
  • the carriages 11 are kept in the final position in which the edges 3 of the elements 1 are against the ends of the blades 2 and this until heat-sealing.
  • the invention takes advantage of the tongues available to the elements of the frame to form the grooves in the blades and thus allow a rigid element-blade connection.
  • This rigid connection allows significant rigidity due to the numerous anchoring points existing between the blades and the frame, which makes the panel indissociable. In addition, these results can be achieved without affecting the aesthetic appearance of the panel since the weld is completely invisible.
