Description
- 1. Field of the Invention
- This invention relates generally to fluid conveying hose assemblies and, more particularly, to an apparatus and method for shaping hose used in fluid conveying hose assemblies.
- 2. Description of the Related Art
- Flexible hose assemblies are often used in engine compartments of motor vehicles to conveying fluids, such as power steering fluid and air-conditioning refrigerants. Unfortunately, in the under-hood design process, routing of the flexible hose is often an afterthought—usually due to its known flexibility—requiring the power-steering and air-conditioning system designers to route the flexible hose around various under-hood components. Accordingly, many under-hood hose assemblies exhibit multiple curves and bends to accommodate the placement of various non-movable engine compartment components.
- Hoses may be pre-formed into any desired shape—so-called shaped hose—by curing green hose on a shaping mandrel. In one known hose shaping process, green (uncured) hose is manufactured in relatively long lengths, cut to size, manually placed onto a shaping mandrel, cured on the shaping mandrel, and then manually removed from the mandrel for use. Once removed, the cured hose retains the general shape of the shaping mandrel. Unfortunately, shaping hose using known processes is cost-intensive—particularly when compared to manufacturing non-shaped hose that is typically cured in the same bulk form it is manufactured.
- Clearly, there is a need for an improved way of imparting the desired shape in a length of hose without subjecting the hose to known “shaped hose” manufacturing processes.
- A shaped hose assembly is provided that includes a length of hose having an external surface and a hose form. In an embodiment, the hose form includes a non-continuous, generally curved wall that extends around the circumference of the external surface of the hose. The wall includes a first axially extending end and a second axially extending end. The hose form also includes at least one bend of predetermined radius. A method for shaping hose is also provided.

FIG. 10 is a perspective view of a hose assembly according to another embodiment of the present invention; and -
FIG. 11 is a detailed view, in partial cross-section, of the hose assembly shown inFIG. 10 . - Referring to
FIGS. 1 and 2 , ashaped hose assembly 20 according to an embodiment of the present invention is shown. In the illustrated embodiment,hose assembly 20 includes a length ofhose 22 having anexternal surface 24 and ahose form 26 positioned over at least a portion ofexternal surface 24. The term “hose” includes, without limitation, generally flexible fluid conveying members, such as the flexible rubber hoses used to conveying power steering fluid and air-conditioning refrigerants in the automotive under-hood environment.Hose assembly 20 is shown inFIG. 1 as having an axis A-A that extends through the center ofhose assembly 20. - As shown in
FIG. 2 ,hose form 24 includes a non-continuous, generallycurved wall 28 that extends around at least a portion of the circumference ofexternal surface 24. When installed onhose 22, aninternal surface 30 ofhose form 26 may uniformly contacthose 22, as shown inFIG. 2 , or may contacthose 22 in any number of locations to impart the desired shape inhose 22. - In an embodiment (shown in
FIG. 2 ),wall 28 extends greater than half-way around the circumference ofexternal surface 24 ofhose 22 and includes a first axially extendingend 32 and a second axially extendingend 34 having a gap G therebetween. As shown in the embodiment ofFIG. 2 , gap G between the first andsecond ends external surface 24 ofhose 22. In this configuration,wall 28 extends sufficiently far around the circumference ofexternal surface 24 to retainhose form 26 onhose 22; however, not so far as to precludehose form 26 from being assembled ontohose 22 in the radial direction. - The extent to which
wall 28 extends aroundhose 22 may be dependent on a number of factors, including the flexibility ofhose 22, the ability ofexternal surface 24 to deform, the flexibility ofhose form 26, and the desired method for assemblinghose form 26 andhose 22 intohose assembly 20. With regard to the latter factor,hose assembly 20 may be assembled along the axial direction by slidinghose 22 into hose form 26 (or alternatively slidinghose form 26 over hose 22), or by radially assemblinghose 22 into hose form 26 (or alternatively radially assemblinghose form 26 onto hose 22), such as by radially snappinghose 22 into hose for 26. The term “snapping” is used without limitation to describe the manner in whichhose 22 is deformed andhose form 26 is flexed ashose 22 is pushed radially intohose form 26. - To impart the desired shape in
hose 22,hose form 26 includes at least one bend of predetermined radius R. For example, in the embodiment shown inFIGS. 1-3 ,hose form 26 includes a single bend having a radius R1. Hose form 26 is installed onhose 22 such thatfirst end 32 is positioned proximate an outer edge of the bend andsecond end 34 is positioned proximate an inner edge of the bend. However, the location ofends FIGS. 1-3 . For example,hose form 26 may be installed onhose 22 such that ends 32, 34 are between the inner and outer edge of the bend with gap facing generally upward or downward. - Referring still to
FIGS. 1-3 ,hose form 26 may be made by roll-forming a piece of relatively flat metal, such as aluminum, into the generally “C” shaped, curved structure shown inFIG. 2 . Prior to imparting a bend(s) inhose form 26,hose form 26 may be installed onto hose 22 (orhose 22 inserted into hose form 26). Alternatively,hose form 26 may be bent to the desired shape prior to assemblinghose assembly 20. In either case, the desired bend(s) may be imparted inhose form 26 using a common tube bender or other device known in the art for bending deformable materials. - As an alternative method of manufacture,
hose form 26 may be cast or molded using any number of materials, including without limitation metals and polymers. For example,hose form 26 may be cast into the required shape, including the desired bend(s), using a metal such as aluminum. In another example,hose form 26 may be injection molded from a suitable plastic such as polypropylene. - Referring to
FIGS. 4 and 5 , ahose assembly 120 according to another embodiment of the present invention is shown.Hose assembly 120 includes a length ofhose 122 and ahose form 126 substantially similar tohose form 26 described above with at least one exception, namely,hose form 126 includes a first bend defined by a first radius R1 and a second bend defined by a second radius R2. As also shown inFIGS. 4 and 5 , the bends provided inhose form 26 may be created along different planes, resulting in ahose form 26 that exhibits a slight twist in its shape and/or bends in two or more different directions. - Referring to
FIGS. 6 and 7 , ahose assembly 220 according to another embodiment of the present invention is shown.Hose assembly 220 includes a length ofhose 222 having anexterior surface 224 and ahose form 226. Likehose form 26 described above,hose form 226 includes a non-continuous, generallycurved wall 228 that extends around at least a portion of the circumference ofexternal surface 224. However, unlikehose form 226 described above,wall 228 need not extend greater than half-way around the circumference ofhose 222 to retainhose form 226 onhose 222. Instead,hose form 226 may include at least oneretainer 229 positioned proximate at least one end ofhose form 226 forgrasping hose 222.Retainer 229 may be integral to hose form 226 (as shown inFIG. 6 ) or may be separate and attached tohose 222 and hose form 226 (not shown).Retainer 226 functions to hold a portion ofhose 222 withinhose form 226 to achieve the desired shape ofhose 222. - Referring to
FIGS. 8 and 9 , ahose assembly 320 according to another embodiment of the present invention is shown. In the disclosed embodiment, hose assembly includes a length ofhose 322 having anexternal surface 324 and at least onehose form 326. In a particular configuration shown inFIG. 8 , hose assembly includes a plurality of hose forms 326, each of which are positioned at a corresponding bend inhose 322.Hose form 326 may be substantially similar tohose form 26 described above with respect toFIGS. 1-3 ,hose form 126 described above with respect toFIGS. 4 and 5 , orhose form 226 described above with respect toFIGS. 6 and 7 . - Alternatively, as shown in
FIG. 9 ,hose form 326 may also include a length of deformable tubing, such as aluminum tubing, having an internal diameter that is at least slightly larger thanexternal surface 324 ofhose 322 and a length that is longer than the length of the desired bend. In this configuration, eachhose form 326 may be formed by sliding each piece of deformable tubing overhose 322 and positioning the tubing proximate the location of the desired bend. The hose and tubing combination may then be placed in a tube bender, or other device known in the art for bending deformable materials, and bent into the desired shape. Once bent, eachhose form 326 is held in place by the bend itself and the relatively close dimension between the internal diameter ofhose form 326 and the diameter ofexternal surface 324. As shown inFIG. 8 , onehose form 326 may be used for each bend inhose 322 or, alternatively, onehose form 326 may be used for more than one bend (not shown). - Another embodiment of the present invention is shown in
FIGS. 9 and 10 , which includeshose 322 and at least onehose form 326′. The illustrated embodiment is substantially similar to the embodiment shown inFIGS. 8 and 9 with at least one exception, namely,hose form 326′ is positioned within aninternal bore 323 ofhose 322, instead of overexternal surface 324. Eachhose form 326′ may be formed by sliding a piece of deformable tubing within hose bore 323 and positioning the tubing proximate the location of the desired bend. The hose and tubing combination may then be placed in a tube bender, or other device known in the art for bending deformable materials, and bent into the desired shape. Once bent, eachhose form 326′ is held in place by the bend itself and the close dimension between the external diameter ofhose form 326′ and the diameter ofinternal bore 323. As shown inFIG. 10 , onehose form 326′ may be used for each bend inhose 322 or, alternatively, onehose form 326′ may be used for more than one bend (not shown). - As will be appreciated, the present invention allows a length of hose to be “shaped” without employing traditional and costly hose shaping processes, such as manufacturing green hose in relatively long lengths, cutting the green hose to size, manually placing the cut green hose onto shaping mandrel, curing the green hose on the mandrel, and then manually removing the shaped hose from the mandrel for use. In contrast, the present invention allows hose to be made in more traditional and cost effective bulk manufacturing methods and then “shaped” using the hose forms described above.
- The present invention has been particularly shown and described with reference to the foregoing embodiments, which are merely illustrative of the best modes for carrying out the invention. It should be understood by those skilled in the art that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention without departing from the spirit and scope of the invention as defined in the following claims. It is intended that the following claims define the scope of the invention and that the method and apparatus within the scope of these claims and their equivalents be covered thereby.
