Description

250 1803

  The invention relates to a fixing device allowing

  both to assemble sheet materials such as woven or nonwoven fabrics, plastic films, or other thin sheet materials including paper. This fixing device can be used to fix any sheet material whose edges are overlapping, abutting, or are superimposed. The device considered can be used in particular as a fastening for closing surgical clothing or gowns that close at the back. Clothes or blouses closing in

  backs are much preferable in operating rooms

  tXon, because their opening is in these conditions opposite to the patient. Clothes open at the back are believed to be more suitable to avoid contamination

  from the surgeon or nurse to the patient, and vice versa.

  These garments are normally closed with a fastening device.

  tion at the neck and by a belt which, fixed to the garment-

  Keep it closed at the height of the person wearing it. Until now, such garments have been closed by fastening straps as described in United States patent 3,868,728, or by metal or plastic fasteners as described in United States patent America 3,988,781. Apparatus for operating rooms has also been attached to the neck, button devices as described in

  U.S. Patent 3,689,939.

  Button devices or fasteners do not give the possibility of obtaining a good fit at the collar of the garment. Their use allows only a limited number of adjustment surfaces to be defined, and their placement is not always appropriate in order to ensure an adjustment.

  correct for a given person wearing the garment.

  The present invention relates to a fixing device

  tion to assemble sheet materials or

  attach other devices to sheet materials.

  This device can be used in particular for closing the neck of a surgical garment or gown. This device can be easily attached to the garment, is inexpensive, and allows the garment to be closed while easily allowing it to be adjusted correctly on people whose sizes are widely different. In addition to the advantages it offers in terms of

  correct fitting of the garment, the fastening device

  déré can be directly attached to the garment without being,

  like 5.1 is classic, sewn or glued.

  The device according to the present invention, used

  sand to close an operating room garment or gown, can also be used to keep the waistband of this garment closed, and to close other garments such as that worn by the patient. Qn can also be used , to fix the tuhes, flg or towels to the surgical sheets, or to fix

  ceg last to other surgical drapes or any other equi-

  pement of the operating room, The fixing device according to this

  invention comprises at least $ three flat parts which are connected

  from one to the other by one or more joints molded from a second piece with these parts. Each part has attachment elements constituted either by nipples coming from a single piece, or by openings in which the nipples

  can be blocked. The flat parts of the fixing device

  tion can be arranged in such a way as to establish the fixing when

  that the sheet materials are overlapping or superimposed,

  or when they are edge to edge. One of the three parts of the dis-

  positive fixing constitutes a central part, and the two external parts can rotate at the aforementioned joints to come face to face with the central part. An edge of the material to be fixed is placed between one of the parts

  outside and the central part, and the other edge of this material

  riau is placed between the other outer part and this central part. The nipples carried by these parts are then engaged in the corresponding openings of another part, which

provides the desired fixation.

  Figure 20, another embodiment in accordance with the

vention,

  - Figure 21, another embodiment according to the-

  - vention, - Figure 22, a sectional view of the device of Figure 21 attached to a garment, There is shown in Figure 1 an isometric view of the fixing device highlighting the various elements ia in the open position, before fixing a sheet material, the device comprises a central part 20 and two external parts 21 and 22 which can rotate in opposite directions at a joint 23. The central part comprises a number of fastening elements in the form of openings 24 which will come into alignment with fastening elements in the form of locking pins 25 carried by the external parts, when the fixing device is tarnished. When the outer parts are driven around the articulation line 23, the pins engage in the

  openings to block the device in the closed position.

  The term "fastener" used in this description or

  in the claims denotes either a nipple 25 or a

opening 24.

  The fixing device can be formed of a single

  part by molding, using an injection molding machine

  tion. FIG. 2 shows the device leaving the mold. The openings 24 are formed in the first part or central part of the device 20. The external parts 21 and 22 are molded in one piece with the part 20 to

  which they are attached by a hinge susceptible-

  pivot 23. The pins 25 are molded with the

external parts 21 and 22.

  As seen in Figure 3, the outer parts 21

  and 22 can rotate in opposite directions around the

  rotary culation 23 to allow blocking between these

  parts of parts covered with sheet material.

  There is shown in Figure 4 the fixing device placed on

  covering parts of a sheet material to be fixed.

  In FIGS. 4, 5 and 6, the material considered bears the references 26 and 27. FIGS. 5 and 6 show a sectional view of the device as shown in FIG. 4, with the parts 26 and 27 held between the part central

  or interior 20 and exterior parts 21 and 22.

  The clearance between the periphery of the openings 24 and the pins 25 can be modified according to the use that is intended to be made of the fixing device. If the material to be fixed can be punctured, the clearance may be low. If it is not desirable for the material to be perforated, the clearance can be increased. This will allow the material to be forced into the openings by the pins 25, without the latter passing through this material. This prevents, for example, the nipples from passing through the material when the fastening device is used on normal clothing. It is also avoided that the tissue or material is passed through when the fastening device is used to close a surgical garment so that there cannot be contamination of the operating room by particles of tissue from the person wearing the garment. Nipples

  push the fabric back into the openings and fix the device

  sitive on this fabric without crossing it. The garment can be detached by removing the nipples from the openings with a movement

reverse.

  In the embodiment shown in FIGS. 1 to 6, the pins 25 are formed on the external parts 21 and 22 and directed inwards, ie towards the central part, when these external parts are driven around the articulation 23 in the closed position. . It is also possible to form the nipples on the central part of the device as shown in Figure 7, The device will work as we just

  to describe it for fixing a sheet material.

  In the embodiment according to the invention shown in Figures 1 & 7, one of the outer parts extends beyond the other. This configuration is obtained by molding the elements such that a flap or external part is in the form of

  U, the other flap or external part being formed by the center

  tre du U. In this form there is only one articulation around which the outer parts turn. The embodiment shown in FIGS. 8 to 1 comprises a first part or central part 30, a second part 31 which can rotate around a joint 33 in one direction, and two elements of a third part 34 which can rotate

  around the joint in the opposite direction to the direction of rotation

  horsefly of part 31. In its other aspects, the device

  fiure.s 8 to it works in the same way as the dispo-

  s4tif des fiture ", 1 to 7, CQmme mentioned above, the clearance between pins 25 and openings 24 may be such that it offers sufficient access space in the openings so that when

  the nipples push the material to be attached through the openings

  There is sufficient space between the edges of the openings.

  tureg and tétonse to allow to block the material in 2Q the opening, without tearing it. There is shown in Figures 11il and 12 a recommended embodiment for nipples and openings. The stud has a frustoconical base 62 which is extended by a bead 63 whose diameter can be more

  large or smaller than the effective diameter of the corresponding hole

  laying. The hole or opening has a chamfer 35 and a clearance. 36 formed in the plastic on the face opposite to the chamfered part. The chamfer e: t the release contribute to the formation of a flexible opening which makes it possible to easily engage the bead of the stud in this opening for fixing, and to easily release this stud to release the fixed material, As seen in the figure 12, a cylindrical bore 37 is provided in the stud 37 which gives it more flexibility, which greatly facilitates its engagement in the openings, and

  which makes it easier to disengage the device from the mold.

  Figures 13 to 16 show other configurations.

  opening statements. In Figure 13, the opening is in the form of a small hole 36 with four radial slots extending from the hole. The plastic material between the slots will deform to allow passage of the stud through the opening. The opening in FIG. 14 is of the same design as that shown in FIG. 13, but has only three radial slots. The opening shown in the figure is only composed of slots formed in the plastic material, and, to establish the attachment, the stud will deform the plastic material by coming into engagement with the quadrangular segments thus defined in this plastic material. We

  shown in Figure 16 a top view of the changeable opening

  braked of figure 12 which constitutes the recommended realization of opening. In the embodiment of FIG. 17, the central part is connected by joints 41 and 42 to the external parts 43 and 44 which are located on either side of this central part. This device can be used to fix edge to edge sheet materials, or with minimum overlap of these materials, as shown in Figure 18 for example for the front of a shirt. It is better to see in Figure 19 that an edge of the material can be placed between the outer part 43 and the

  central part 40, the pins 25 being blocked in the openings

  tures 24 for fixing the material. Another edge of the material

  can be placed and held in position between the outer part

44 and the central part 40.

  FIG. 20 shows another embodiment in accordance with the present invention used for fixing in light overlap, or even edge to edge, sheet materials. In this device, the central part 50 has four openings 24. Two external parts 53 are connected on one side of the central part by an articulation 51 coming from a molding

  in one piece and each of these parts carries a stud 25.

  Another outer part 54, which carries two nipples, is

  connected on the opposite side of the central part by an ar-

250 1803

  ticulation 52 coming from a one-piece molding. The dis-

  positive is used as described for the device shown in Figure 17. The device shown in Figure 2G provides better fixation than that of Figure 17 since it has a greater number of nipples and openings . The device of Figures 21 and 22 is similar to the device of Figure 17, but its overall length may be shorter. To compensate for this reduction in length, two circular cutouts or openings 60 and 61 (in the external parts) are provided for the passage of the nipples.

  engaged in the openings and repelling the material to be fixed.

  The cutouts 60 and 61 are aligned with the openings - 24

  constituting attachment element in the first part or par-

  central tie of the device, for the passage of the pins in the openings 24 and in or through the cutouts 60 and 61, and the establishment of a tight fixing. The layout is

perfectly illustrated in figure 22.

  As shown in Figures 17, 20, 21 and 22, one can provide a tab 56 come by molding in one piece on one of the flat parts, forming an additional part

  when detaching the device.

  The fixing device can be molded from

  a suitable flexible thermoplastic material such as polyole-

  thylene or polypropylene, the flexibility of which is sufficient to allow the nipples to enter the openings without tearing the fabric. The part of the fixing device which surrounds the openings can be thinner than the rest of the flat parts to increase flexibility when the tissue is pushed back into the openings. This is what is shown in Figure 12. The thinned parts can be formed during the molding of the device, or can be formed on the

  device finished by cutting or grinding.

  The number of nipples can be changed. There must be at least one stud on each external part according to the embodiments of FIGS. 1 to 6 and 8 to 11, and at least two studs in the central part according to the embodiment of FIG. 7. It is recommended to plan at

  minus two nipples to fix each thickness of material.

  The presence of several nipples per thickness of fabric to be fixed gives greater stability to the device

fixing during use.

  The fixing device according to the present invention has been described as a device used for closing a surgical garment; but 1 it can be used for many other applications. It can be used, for example, to attach disposable or reusable diapers. It can also be used to attach sheet materials to wires, ropes or cylindrical supports. For such applications, the joint is extended to give it, in the closed position, a dimenson corresponding to the diameter of the wire, cordage or cylindrical support to which must be

fixed the sheet material.
