Definitions

  • the present invention belongs to the field of facial protection devices, and relates in particular to a kit for an integral protection visor, the assembly of which is simplified and to an integral protection visor assembled from this kit.
  • Known integral protective visors generally comprise a protective screen, dimensioned to extend in front of the entire face of the user, and holding means to which the protective screen is attached and which serve to keep the protective visor on the user's head.
  • the screen will be made of a material highly resistant to impacts and the holding means will consist of a plastic helmet part and a strap making it possible to keep the visor in position with the helmet part at least partially covering the top of the user's head.
  • the screen is generally fixed by gluing or screwing on the helmet part, which is configured so that the screen is positioned away from the face of the user.
  • the screen is generally made of a plastic material which does not exhibit resistance to particularly high impacts, and has a lower thickness than that of protective visors for the construction field, which allows to reduce the weight of the full visor.
  • the holding means generally consist of a simple strip of fabric which is fixed, sometimes in a removable manner, at the level of the upper edge of the screen and makes it possible to be adapted to the size of the user's head, for example a band of elastic fabric.
  • An intermediate piece of comfort made of foam material is also permanently fixed, generally by gluing, along the upper edge of the screen, in order to be interposed, in use, between the screen and the user's forehead.
  • the manufacturing processes for protective visors for the medical field can be more or less complex, depending in particular on the way in which the different parts are fixed to each other, such as for example the way in which the holding means are fixed to the screen. .
  • these protective visors are delivered either in the already assembled state, or in the state not entirely assembled but with the comfort piece permanently fixed to the screen, so that the volume occupied by these visors of protection during storage and transport is important.
  • full protective visors can be used in combination with masks, whether surgical or filtering, such as in particular FFP masks.
  • full protective visors also protect these masks from the rain, and therefore prevent these masks, precious and available in large numbers. limited, are rendered inoperative very quickly by rain.
  • the present invention thus aims to provide a solution making it possible to manufacture and assemble integral protection visors in a particularly simple and rapid manner and with a small volume during storage and transport.
  • the intermediate part (s) therefore serve for the comfort of the user, to move the screen away from his face and to allow the screen and the headband to be attached.
  • the assembly of the integral protective visor with the kit according to the present invention can be carried out by the end user by the simple interlocking of different elements. This makes it possible to avoid more complex operations, such as gluing, and also to store and transport the various elements in a stacked state and separate from each other. The volume occupied by the various elements during storage and transport is therefore greatly reduced compared to existing full protective visors.
  • the fitting means can be obtained by cutting an operation from a block of foam material, an operation in itself simple, rapid and very easy to reproduce.
  • the user does not necessarily need to dismantle it before removing it, he can, if he wishes, simply remove it from his head while still in the assembled state, then put it back on his head when he wants to use it again.
  • the through-hole or mounting holes are located in the central region of the strip and that the means for maintaining the latter in its loop form are formed by any means capable of fixing the two free ends of the strip l 'to each other, for example by hooking, press stud, etc.
  • the band can be formed by a band already in a loop, and therefore having no ends, in which case said loop-shaped holding means may be considered to be the material itself. of the headband, which could for example be of fabric, optionally elastic.
  • the band is a strip of material having two free ends
  • the mounting through holes comprise, starting from a first end, a series of first through holes and in the region of a second end. , opposite the first end, at least one second through hole, so that, during assembly, the mounting of the strip on the intermediate part or parts comprises introducing one or more fitting means in one or more first holes through or in the second through-hole (s), then form the loop by bringing the free part of the strip in front of the intermediate part (s) and mounting it on one or more fitting means by introducing the latter into the second through-hole (s) , respectively one or more first through holes.
  • the or each fitting means is an elastic fitting means, preferably reversible, which allows secure assembly of the full protective visor.
  • the or each fitting means may comprise a projection the free end of which, wider, constitutes a stop head offering at least one stop face oriented towards the external face of the intermediate part and which, in use, will come to rest against the band, the stopper tapering in the direction going away from the stop face so as to allow the introduction into the through holes of the protective screen and of the headband.
  • the or each projection comprises a body part in the form of a rectangular parallelepiped and whose longitudinal direction is parallel to the height direction of the outer face of the intermediate piece, and the stop head has a cross section, taken perpendicular to the longitudinal direction of the body part, which is in the shape of a regular trapezoid, and the through holes of the protective screen and the headband are rectangular and of larger dimensions than those of the body part but smaller than those of the stop head at the level of the stop face.
  • Such a configuration of the stopping means allows safe immobilization of the screen and of the strip on the intermediate part (s).
  • the kit according to the present invention comprises a single intermediate piece, preferably in the shape of a half-moon. This allows for even faster manufacturing and assembly.
  • This single intermediate piece could comprise a single nesting means, for example extending along the length direction of the external face of the intermediate piece.
  • the intermediate part comprises several holding means distributed over the length of its outer face, which helps to improve the immobilization of the screen and of the strip on the intermediate part.
  • the single intermediate piece is more tapered in an end region of the latter, so that the depths of the fitting means in this end region are greater than that of the other means. casing. This makes it easier to overlap the band in this area.
  • the or each intermediate piece has one or more recesses in its external face, extending over the entire height of the latter, so as to release, in use, at the level of the or each recess, a space between the protective screen and the outer face of the intermediate piece, thus forming one or more passages through which air can escape and thus prevent the formation of fogging on the protective screen, and, preferably, the recesses being provided in the central region of the outer face, in the length direction of the latter.
  • the protective screen is made of a flexible material allowing it to be flattened during storage and transport and bent during assembly to the intermediate part (s), such as for example plastic, such as polycarbonate, poly (vinyl chloride) (PVC) or poly (ethylene terephthalate) (PET).
  • plastic such as polycarbonate, poly (vinyl chloride) (PVC) or poly (ethylene terephthalate) (PET).
  • PVC poly (vinyl chloride)
  • PET poly (ethylene terephthalate)
  • the band can be made of any suitable material, such as cardboard, paper, plastic, etc.
  • the band is made of a foam material.
  • the same foam material can be used for the intermediate part (s) and the band, such as for example polyethylene foam, polyurethane foam, rubber foam, etc.
  • the present invention also relates to an integral protective visor, characterized in that it is assembled from the kit as defined above.
  • the visor 1 comprises a screen 2, a band 3 and an intermediate part 4, the kit being composed of these same elements.
  • the screen 2 is mounted on the intermediate part 4 and sandwiched between the latter and the strip 3.
  • the screen 2 is a screen similar to known screens, in that it is transparent and sized to extend in front of the entire face of the user.
  • the screen 2 is made of a relatively flexible material, allowing it to be laid in a flat state for storage and transport, and in a curved state, in which it follows the curvature of the intermediate piece 4, once the visor 1 assembled.
  • Polycarbonate can be mentioned, for example, as a suitable material for the screen 2.
  • the screen 2 differs in that it comprises a series of through holes 20 evenly distributed along the region of its upper edge 21.
  • ten through holes 20 are provided.
  • the through holes 20 are rectangular, with their longitudinal direction oriented in the vertical direction when the visor 1 is in use. These through holes 20 are obtained by simple cutting.
  • the band 3 participates in maintaining the screen 2 on the intermediate part 4 and serves to maintain the visor 1 on the user's head.
  • the strip 3 is a rectangular strip of material, here of foam material which has the advantage of being very light.
  • first through holes 30, regularly distributed with respect to each other extends from a first end 31 of the strip 3, and that three second through holes 32 are provided in the region a second end 33 of the strip 3.
  • the first and second through holes 30 and 32 are rectangular, of the same dimension as the through holes 20 of the screen 2, and are oriented such that their longitudinal direction is perpendicular to the longitudinal direction of the strip 3, and therefore in the direction vertical when visor 1 is in use.
  • first through holes 30 can be provided on the strip 3 than of through holes 20 on the screen 20, for example a larger number to maximize the adjustment pitch as illustrated in the drawings.
  • first through holes 30 can be provided on the strip 3 than of through holes 20 on the screen 20, for example a larger number to maximize the adjustment pitch as illustrated in the drawings.
  • the intermediate part 4 is a generally half-moon part obtained in a block of foam material.
  • the intermediate part 4 thus has an internal face 40, intended to come into contact with the user's forehead, and an external face 41, opposite the internal face 40.
  • Elastic nesting means 42 are formed integrally with the rest of the intermediate part 4, by cutting the block of foam material, to put the assembly of the screen 2 and the strip 3 on the intermediate part 4 by elastic fitting.
  • ten elastic fitting means 42 are provided, namely one for each through hole 20 of the screen 2, which are thus distributed along the outer face 41 at a spacing corresponding to that between the through holes 20 once the screen 2 is curved to follow the external face 41.
  • Each elastic fitting means 42 is formed by a projection 43 extending over the entire height of the outer face 41 and comprising a body part 43a and a stop head 43b.
  • the body part 43a has the shape of a rectangular parallelepiped, with its longitudinal direction oriented in the height direction of the outer face 41.
  • the depth of the body part 43a namely its dimension in the direction perpendicular to the outer face 41, is greater than that of screen 2.
  • the dimensions of the body part 43a are chosen so that the body part 43a can extend through the through-holes 20 and the first through-holes 30 and, where appropriate, the second through-holes 32, once the latter are aligned with each other. with the others.
  • the stop head 43b extends from the body part 43a, over the entire height of the latter and away from the outer face 41, and has a cross section in the shape of a regular trapezoid with its base at the level of the body part 43a.
  • the stop head 43b has thus a stop face 43c directed towards the external face 41, and two inclined lateral faces 43d up to its free end.
  • this shape of the stop head 43b makes it possible to facilitate the introduction of the fitting means 42 through the through holes 20, 30 and 32, while preventing the strip 3 and the screen 2 to separate from the intermediate part 4 inadvertently.
  • the outer face 41 has a central recess 44 between the two central fitting means 42, two lateral recesses 45 and a small recess 46.
  • These recesses 44, 45 and 46 extend over the entire height of the outer face 41 and define passages which, in use, allow air to escape and thus prevent the formation of fogging on the screen 2. .
  • These recesses 44, 45 and 46 have a semi-cylindrical bottom and differ by their depths, the lateral recesses 45 are deeper, and by their widths, the small recess 46 having a width less than the distance between the two fitting means 42 consecutive between which it is, while the width of the recesses 44 and 45 is equal to this distance.
  • the principle underlying the assembly of the screen 2, of the strip 3 and of the intermediate part 4 is a simple fitting, and is therefore particularly simple.
  • the user it suffices for the user, initially, to mount the screen 2 by inserting the fitting means 42 through the through holes 20, until the screen 2 is placed against the external face 41.
  • the user can then, for example, mount the region of the second end 33 on the intermediate part 4 by introducing the three successive fitting means 42 from one end of the outer face 41, into the three through holes 32. of the band 3.
  • the user then passes the band 3 behind his head and, depending on the size of his head and the tightening he wishes to apply to the latter, he introduces the other fitting means 42 into the first through holes 30.
  • the introduction is simple, due to the shape of the stop heads and the use of foam material.
  • the body parts 43a can be sized to take into account the flexibility of the foam material used for the strip 3 so as to allow the two ends of the strip 3 to overlap on the fitting means 42, while allowing the faces d 43c stop the other fitting means 42 to be in contact with or near the outer face of the strip 3 even in the absence of overlap.
  • the user then mounts the screen 2 on all the fitting means 42, the screen 2 then being partly against the region of the second end 33 of the strip 3 and the external face 41 of the intermediate part 4 Finally, as before, the user forms a loop with the band 3 to bring the remaining part in front of the intermediate part 4 and introduce the fitting means 42 into the first through holes 30.
