  • this invention relates to an improved bio- conforming or biomorphic pod for mounting onto an appropriate implement surface, and a related method of pod production, wherein the conformable pod incorporates a viscous and tacky gel material adapted for custom-fit shape deformation in response to a minimal applied inertia or pressure, and for substantially pressureless retention of the deformed shape until the pod is released by the user. When released, the pod exhibits a memory characteristic for subsequent relatively slow return to an initial nondeformed shape.
  • Manual implements generally incorporate a handle or related structure having a size and shape for appropriate manual grasping and manipulation of the implement during normal intended use.
  • the handle structure comprises an elongated rigid element having one end securely connected to the implement, such as a cooking pot or pan, a hair brush, a tool head, etc.
  • the manual implement is normally grasped directly about the body thereof, such as in the case of writing and other marking instruments, baseball and softball bats, etc.
  • Other manual implements are adapted for fingertip manipulation and thereby include one or more keypads for fingertip depression, e.g., keyboards, musical instruments such as a clarinet, saxophone, trumpet and the like.

  • Increased sleeve stiffness is, of course, contrary to a desire to provide a significantly reduced and substantially minimized pressure threshold for initiating deformation of the deformable grip.

  • the conformable pod may be constructed by initially forming the outer skin as by injection, tumble, compression, or blow molding, or the like.

  • the assembled skin 1 8 (defined by the perimeter side wall 24 and the face wall 26) and substrate 20 cooperatively define the enclosed cavity or chamber 1 6 filled with the deformable gel material 1 4.
  • a fastener element 28 such as a film of pressure sensitive adhesive of the like is carried at the underside of the substrate 20 for quick and easy affixation of the assembled pod 10 onto a selected implement 1 2 (FIGS. 6-7).
  • FIG. 2 illustrates a peel-off liner 30 of paper-based material or the like for exposing the fastener film 28 immediately prior to mounting of the conformable pod 1 0 onto the selected implement.

  • the molded skin 1 8 is supported in an inverted orientation for facilitated pour-in reception of the gel material 1 4, as illustrated by arrow 42 in FIG. 4.
  • the molded skin 1 8 is substantially filled with the gel material, which preferably comprises a coagulated or partially coagulated or catalized gel such as a highly viscous and tacky silicone or polyurethane gel material wherein the molecules are believed to be attached but not firmly held thereby permitting relative movement in response to applied manual pressure.
  • the tacky or sticky character of the gel material causes the gel to adhere or stick intimately with the inboard or underside surface of the inverted molded skin 1 8, but substantially without fusing or conjoining of the gel material 14 with the skin 1 8.
  • a molded skin 1 8 formed from a suitable silicon-based film material it is believed that a molecular attraction between the skin 1 8 and the gel material 1 4, short of molecular bonding, effectively resists sliding displacement between the skin 1 8 and the gel 1 4 for enhanced pod displacement during use.
  • Exemplary gel materials include Silgel 61 2, available from Wacker Chemical Corporation, Adrian, Michigan, and ER 801 5 GE TSE3053, both available from GE Silicones, Wilton, Massachusetts. Importantly, such gel materials exhibit a memory characteristic whereby the material deformably responds to relatively lightweight or minimal applied pressure, but thereafter, following a time delay of at least about two seconds after user release, the gel material returns relatively slowly (over a period of at least five seconds or more) to its initial nondeformed shape.

  • a containment die 46 may be assembled with the lower mold die 38 to retain the thus-poured liquid substrate-forming resin until it cures sufficiently in adhered, substantially sealed engagement with the peripheral edge 22 of the skin 1 8.
  • the thus-assembled cushioned pad 1 0 can be removed from the mold die 38 and suitably assembled with the fastener element 28, as previously described (FIG. 2).

  • the gel material 14 retains the deformed shape in a substantially pressureless manner, i.e., substantially without requiring the user to exert a deformation force for the purpose of holding and retaining the pod 1 0 in the desired custom-fitted geometry.

  • the gel material 14 maintains the deformed shape for at least a short delay period following release of the applied pressure therefrom. That is, the gel material 1 4 tends to retain the deformed shape for at least about two seconds or more, following release of the applied pressure, and thereafter returns slowly over a period of about four seconds or more to the initial nondeformed shape.

  • this support strip 95 may be co-molded within the pod, generally at an inboard side of the rear-side substrate 320 to provide a stiff and stable base for the mounting bolts 88.
  • the support strip 95 comprises a layer of thicker and less deformable material in comparison with the outer skin 31 8, suitable for co-molded embedment of the bolt head portions 91 therein.
  • the support strip 95 may be formed from a rigid material, such as metal or plastic.
  • the support strip 95 may incorporate and comprise the rear-side substrate 320 of the conformable pod.
  • the gel material 314 responds to user-applied pressure to conformably and deformably respond so that the ribs 86 collectively compress to assume a custom anatomical configuration.
  • the gel material 314 will slowly substantially to its original non-deformed shape, thereby returning the pod substantially to its original rib and trough configuration.
  • different types of mechanical fasteners may be employed, such as magnet fasteners carried by the conformable pod at the rear side thereof for quick and easy attachment to the structure of a selected article or implement.
  • a magnet can be carried at a rear side of the pod for attachment to a suitable structure which may include a mating magnet of opposite polarity.
  • the rear-side substrate of the conformable pod may be designed for direct attachment as by co-molding directly onto the structure of the selected article or substrate.

Abstract

L'invention concerne un module conformable et un procédé de production associé, le module définissant une structure souple adaptée pour se déformer en réponse à une pression minimum appliquée manuellement, c'est-à-dire par contact avec une certaine partie du corps, et pour conserver une configuration sensiblement déformée en l'absence d'une application continue de pression manuelle. Le module comprend une matière visqueuse et collante de type gel contenue dans une chambre fermée définie au moins en partie par une membrane extérieure relativement mince et facilement déformée fournissant une résistance minimale à la déformation. Sous une forme préférée, la matière de type gel contenue est un gel coagulé ou partiellement coagulé, comme un gel à base de silicone, adapté pour se déformer en réponse à une pression minimale appliquée, et pour conserver la forme sensiblement sans pression après la déformation, opération suivie par un retour relativement lent (au moins deux secondes ou plus) à une forme non déformée initiale lors de la libération du module.
