    GLAND-SHAPED JOINT PROFILE
    FIELD
    The present description relates to a joint between a plurality of surfaces.
    CONTEXT
    Joints can be used between two adjacent surfaces (and / or surfaces with a space between them) to prevent the flow of air, liquid, and other unwanted elements through the otherwise visible space between the two surfaces. However, the footprint of these joints may have to meet strict constraints. Often an omega joint with a standard circular cross section (see FIGURE 1) may not be suitable for the packaging constraints of an application. It would be preferable if a seal was designed to meet the performance needs of various applications, while maintaining a reduced footprint on the seal bearing / depressor and / or on the seal fixing surface in the design specifications.
    ABSTRACT
    A joint comprising a transverse profile generally in the form of an acorn is described herein. In addition, a joint having a non-circular transverse open interior profile is described herein. According to various embodiments, a seal having a fitting or retainer configured to secure the seal to a first surface, an external contact surface configured to engage a second contact surface, and an internal open passage is described herein. A first curved interior surface (interior to the passage) can be configured to deform under force at a greater angle of curvature. Second and third interior curved surfaces, internal to the passage, can be configured to deform at a lower angle of curvature. The second interior curved surface and the first interior curved surface are connected via a substantially non-curved interior surface. The third curved surface and the first curved surface are connected via a substantially non-curved interior surface.

    DETAILED DESCRIPTION
    The detailed description of the exemplary embodiments of the present refers to the accompanying drawings, which illustrate exemplary embodiments by way of illustration and its best mode. While these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the inventions, it should be understood that other embodiments can be made and that logical, chemical and mechanical modifications can be made without departing from the scope of inventions. Thus, the detailed description herein is presented for illustration purposes only and without limitation. For example, the steps described in one of the method or process descriptions can be performed in any order and are not necessarily limited to the order presented. In addition, any reference to the singular includes more than one embodiment, and any reference to more than one component or step may include a particular embodiment or step. In addition, any reference to attached, attached, connected or the like may include permanent, removable, temporary, partial, complete and / or any other attachment option. In addition, any reference to contactless (or similar expressions) may also include reduced or minimal contact.
    Conventional omega seal profiles, with reference to FIGURE 1, have a limited compression range (eg, 10% to 50% of the diameter of the decompressed seal).
    To design higher deflections, a larger internal diameter is required. However, this larger diameter can exceed the packaging constraints and prevent this larger deflection range. The acorn-shaped seal 110 (see FIGURES 2-3B) having a generally acorn-shaped profile as described herein can act to alleviate this and other problems.
    According to various embodiments and with reference to FIGURE 2, a joint, configured for a location between two adjacent surfaces, having a generally open interior which may include a transverse interior profile generally in the form of an acorn is described herein. For example, unlike "omega" seals with generally circular interiors (as illustrated in FIGURE 1) the acorn-shaped seal 110 described herein is larger than its longest interior length (generally along the Y axis as illustrated in FIGURE 2), it is therefore wider than its widest width (generally along the X axis as illustrated in FIGURE 2). Otherwise presented, a measurement from the middle of the longest inner span of the acorn-shaped joint 110 between a first interior surface at location B '”and a second location B” ”(usually along of the Y axis) gives a length greater than a measurement from the middle of the widest inner seat of the acorn-shaped joint 110 between a third inner surface at the third location B 'and a fourth location B ”(generally the along the X axis). The tassel-shaped seal 110 may include at least three interior surface curves, always with reference to FIGURE 2, generally via locations 170, 175 and 180. The interior curves, unlike a seal with a transverse profile "D", can be greater than 90 degrees. The acorn-shaped seal 110 includes a generally non-circular transverse internal profile. According to various embodiments, the acorn-shaped seal 110 is generally symmetrical. The acorn-shaped seal 110 can be made of any desired deformable material, such as a polymer (eg, silicone). According to various embodiments, internal multi-ply arrangement inside the seal in the form of a silicone tassel 110 may be different depending on the location. For example, near the top of the acorn-shaped joint, 3 plies of carbon fabric can be used while 2 plies can be found in other locations. In this way, the acorn-shaped seal 110 is configured to have a relatively greater rigidity at the level of the tip and / or from the top and configured to deform in all places, thus giving the desired deformed shape. (See FIGURES 4A to 4F)
    As illustrated in FIGURE 3A, the tassel seal 110 can be configured to allow the use of a conventional retainer 60 to securely hold the tassel seal 110. For example, flanges 190, 195 can be inserted in a trace / a retaining device 60 which wraps partially or completely around each flange 190, 195. The retaining device 60 can extend in a direction perpendicular to the axes X and Y as illustrated on FIGURE 3A. A space 130 can be created in the acorn-shaped seal 110 in order to release the heads of the fixing device which fix the retaining device 60 to a secondary surface. The acorn-shaped seal 110 can be permanently and / or semi-permanently fixed in position inside the retaining device 60 using adhesives, mechanical fixing devices, by press fit and /or similar. For example, a mechanical fastening device can be inserted through the base of the seal in the form of a seal 110, internally through the profile of the seal in the form of a tassel. According to various embodiments, this can be achieved by molding a metal plate inside the silicone at the base of the acorn-shaped joint 110 and by welding studs or nut plates to the acorn-shaped joint 110 .
    As illustrated in FIGURE 3B, the acorn-shaped seal 110 can be connected between a plurality of adjacent surfaces in any desired manner. For example, a flange, such as flange 65, can be connected to the acorn-shaped seal 110 to position and retain the acorn-shaped seal 110 on a surface 210. The flange 65 can be of any shape, and turn the acorn-shaped seal 110 in any desired direction. The flange 65 can be connected and / or integrally formed with the acorn-shaped seal 110. The flanges 190, 195 can be removed or kept in the flange mounting designs if desired. A mechanical fastening device can be inserted through the flange 65 and / or the flange 65 can be glued and / or welded to a secondary surface if desired.
    As shown in FIGURES 4A to 4F, the tassel seal 110 can be configured to be used at various levels of compression. In another way, the acorn-shaped seal 110 can be compressed as a function of a force applied by a second surface 410, such as an unmounted contact surface. For example, according to various embodiments, FIGURE 4B illustrates 10% compression; FIGURE 4C illustrates 20% compression; FIGURE 4D illustrates 30% compression; FIGURE 4E illustrates 40% compression; and the
    FIGURE 4F illustrated 50% compression. Compared to an omega joint (as illustrated in FIGURE 1), to obtain the equivalent performance, a larger diameter would be necessary to obtain the compression range of the acorn-shaped joint 110. However, the width necessary for this Omega seal type often exceeds the packaging constraints of the holding location. In addition, for the omega seal, as the compression range changes, the contact area on the seal depressor has a high variation, which varies depending on the amount of compression. On the contrary, the acorn-shaped seal 110 compresses to a comparatively small contact imprint. The contact footprint is reasonably linear within the 30% compression range. Although the preferred direction of force on the tassel joint from an adjacent contact surface is along the Y axis (see FIGURES 4A to 4F), the tassel joint 110 is configured to adapt to a certain angularity in the surface of the depressant and / or the direction of the applied force. The transverse shape of the tassel-shaped seal 110 makes it possible to obtain higher compression ranges while retaining the limited special constraints of the existing seals.
    According to various embodiments, the acorn-shaped seal 110 may include an open internal passage 120. A first internal curved surface 180 inside the passage is configured to deform under force at a greater angle of curvature. This upper angle of the first curved internal surface 180 can be substantially flat. A second curved interior surface 170 and a third curved interior surface 175 internal to the passage may be configured to deform at a lower angle of curvature. This can be between 5 and degrees. The second curved interior surface 170 and the first curved interior surface 180 can be connected (as seen in cross section) via a substantially non-curved interior surface 185. The third curved interior surface 175 and the first curved interior surface 180 can be connected ( as seen in cross section) via a substantially non-curved interior surface 187.
    The tassel seal 110 can be configured as part of a flame retardant seal between two compartments and / or zones. The acorn-shaped seal 110 can be configured as a performance seal, so as to prevent and / or reduce the flow of air or fluid through a space between two adjacent and / or nearly adjacent surfaces. The tassel-shaped seal 110 can be configured for use in aeronautical applications, such as a seal between two moving parts such as a pressure and / or flame retardant seal. For example, the tassel seal 110 can be used as part of a thrust reverser. However, the tassel-shaped seal 110 is not limited to aeronautical applications and may be applicable for use when a filler coating between pluralities of mobile or connected surfaces is desired. A non-limiting example may include, on elevator doors, on an access hatch, electrical components, computer server doors, windows, gates and / or the like.
