Description:
TECHNICAL FIELD 
     The present application relates to the field of mounts for use with a cable tie, and more particularly to saddle mounts therefor. 
     BACKGROUND OF THE ART 
     Cable ties are well known for holding cables to a fixed structure. Such cable ties are used, for example, to mount electrical wiring and similar items to the exterior of a gas turbine engine. However, in order to access the underlying structure, such as to open or service the gas turbine engine, it is often required to remove the cables, etc., to allow access. Typically, this is done by simply cutting the cable ties and then removing the cable, however, the cables may be nicked or damaged by the manipulation of the cutting tool used to cut the ties. Thus, either additional time or care must be used in cutting, and/or occasional repair or replacement of nicked cables is required. Neither of these situations is desirable, and therefore improvement is desired. 
     SUMMARY 
     It is an object of the present disclosure to provide a novel method for releasing elongated flexible items from a saddle mount. 
     According to one aspect, there is provided a saddle mount for connecting elongated flexible items to a structure comprising: a base adapted to be secured to the structure; a pair of spaced-apart walls each projecting from the base to a wall free end, the walls thereby forming a saddle with the base, the walls each having an aperture between the base and the free end for receiving a tying member, the walls each having inner surface facing the other wall and an outer surface on an opposite side of the wall, at least one of the spaced-apart walls having in its outer surface at least one recess, the recess disposed between the aperture and the free end, the recess extending laterally across the outer surface a distance greater than a lateral width of the aperture, the recess thereby configured to permit a cutting surface to access an underside of the tying member extending through the apertures. 
     In accordance with another aspect, there is provided a cable mounting assembly comprising: a mount configured to be secured to a supporting structure, the mount having an interior area and at least one outer surface, the interior area configured to receive a cable-like item, the outer surface having an aperture for permitting insertion of an elongate cable tying member through the aperture for securing said item to the mount, the outer surface extending to a free end, the outer surface having means for providing access to an underside of the tying member to facilitate cutting the tying member, said means disposed between the aperture and the free end. 
     In accordance with a still further aspect, there is provided a method of providing a cable mounting apparatus, comprising: providing a mount having an open ended body having an interior area for receiving cables along a main axis, the body having an outer surface opposite to said interior area; defining a passage in said open ended body transversally to said main axis for receiving a cable tie; providing a groove on the outer surface of the body, and sizing the groove to permit a cutting tool to access an underside of the cable tie.

     DETAILED DESCRIPTION 
     In order to better understand the present disclosure, it is first helpful to consider the context of the prior art. In  FIG. 1 , there is illustrated a saddle mount in accordance with the prior art. The saddle mount is used to connect elongated flexible items such as cables, wires, hoses or pipes to a structure, using a cable tie or other tying member. The prior-art saddle mount  10  has a base  11  with a centrally-opened counterbore  12  to secure the saddle mount  10  to a structure using a fastener. Walls  13  are provided on opposed sides of the base  11 , and feature inclined surfaces  14  to form a saddle with the base  11 , and passages  15 . A cable tie (not shown) is passed through the passages  15  and straps the cables (not shown), thereby securing the cables to the saddle mount  10 . To release the cables from the saddle mount  10 , a cutting tool must be used to cut the tie. 
     Now referring to  FIG. 2 , there is shown an embodiment of a protective saddle mount  20  in accordance with the present disclosure. The saddle mount  20  is used to connect elongated flexible items to a structure. The elongated flexible items may be, amongst numerous possibilities, cables, wires, tubing, and pipes. For simplicity purposes, the saddle mount  20  is hereinafter described and illustrated as being used with cables. 
     The saddle mount  20  has a base  21  by which it is secured to a structure. The base  21  may have a generally planar undersurface so as to be used against a flat surface of a structure. The base  21  may have different shapes or configurations as a function of the structures to which it will be connected. For instance, the undersurface may be semi-circular or arcuate to be connected to pipes or like rounded surfaces. 
     As shown concurrently in  FIGS. 2 and 4 , the base  21  has a counterbore  22  with a central throughbore. The counterbore  22  accommodates the head of a fastener A such as a bolt, a screw, a nail or the like, while the connector portion of the fastener (e.g., threaded rod) passes through the central throughbore to secure the base  21  to a structure. The base  21  may have more that one counterbore  22 , or may be provided with alternative connection means to be secured to a structure. As illustrated in  FIG. 4 , the counterbore  22  is sized such that the head of the fastener A is fully received therein. 
     Walls  23  project from opposite sides of the base  21 , thereby giving the saddle mount  20  a V-shape, i.e., saddle shape. The walls  23  each have an inclined inner surface  24 . The inclined inner surfaces  24  define an interior area of the saddle, against which cables B ( FIG. 4 ) abut when axially positioned to the saddle mount  20  and strapped thereto. The walls  23  each have an outer lateral surface  25 , against which a tying member C lies when connecting the cables B to the saddle mount  20 . In  FIGS. 3-4 , the tying member C is illustrated as being a cable tie (i.e., a tie wrap), but may be any other suitable tying member, such as a rope, hose connector, wire or the like. A junction between the inclined inner surface  24  and the outer lateral surface  25  may be rounded, whereby the free ends of the walls  23  do not expose straight edges. 
     Passages  26  are defined in each of the walls  23 . The passages  26  may be adjacent to an upper surface of the base  21 . The cable tie C passes through the passages  26  to strap the cables B to the saddle mount  20 . The saddle mount  20  may have a single passage  26 , for instance passing through the base  21 . 
     Referring concurrently to  FIGS. 2-4 , a groove  27  is formed in the outer lateral surface  25  of each of the walls  23 . As shown in  FIG. 4 , the groove  27  separates two portions of the lateral outer surface  25  against which the cable tie C lies, such that a space is defined between the surface of the groove  27  and the cable tie C. The space is used to accommodate the tip or nose of a cutter (e.g., a side cutter, a blade of a cutter or of a pair of scissors), to cut off the cable tie C. 
     The groove  27  is transversely positioned with respect to the cable tie C, to minimize the width of cable tie C to be sectioned to release the cables B from the saddle mount B. The groove  27  may have other orientations with respect to the cable tie C. 
     In  FIGS. 2-3 , the grooves  27  are each shown extending on the full width of their respective walls  23 , to facilitate the manipulation of the cutting tool in the space. The groove  27  may be provided with an abutment wall at an end thereof to stop the movement of the cutting tool at the end of the groove  27 . In  FIGS. 2-4 , both walls  23  have a groove  27 . The saddle mount  20  may be provided with a single groove  27 . 
     The saddle mount  20  is made of any suitable material, such as polymers, metals, alloys, composite materials or the like. In an embodiment, the saddle mount  20  is an integrally molded or cast into a single piece. 
     Now that the saddle mount  20  has been described, a method for strapping cables with and releasing cables from the saddle mount  20  is described. 
     The saddle mount  20  is firstly secured to a structure. Referring to  FIG. 4 , the saddle mount  20  is secured to a surface D. The base  21  lies on the surface D, and the fastener A is connected to the surface D with the head of the fastener A being accommodated in the counterbore  22 . In the embodiment of  FIG. 4 , the fastener A is a bolt that is screwed into a tapped hole in the surface D. 
     An end of the cable tie C is then threaded through the passages  26 . The cables B are then positioned within the saddle of the saddle mount  20 . In an embodiment, the cables are already interconnected into a harness of cables, whereby the harness is positioned within the saddle of the saddle mount  20 . As shown in  FIGS. 3-4 , the cables B may extend beyond the rounded edges of the walls  23 . The ends of the cable tie C are subsequently tied to one another, and the cable tie C is tightened about the cables B in the manner shown in  FIGS. 3 and 4 , whereby the cables B are strapped to the saddle mount  20  by the cable tie C. As shown in  FIGS. 3-5 , the cable tie C interfaces with the outer lateral surfaces  25 . 
     Referring to  FIG. 5 , in order to release the cables B from the saddle mount  20 , a portion of a cutting tool E is inserted into the space defined by the surface of the groove  27  and by the cable tie C. The cutting tool therefore accesses the cable tie C, which may be sectioned while the wall  23  forms a shield between the cutting tool and the cables B. Therefore, the cables B are shielded from the cutting tool E when the cable tie C is being cut off to release the cables B. The saddle mount  20  may remain secured to the structure D for subsequent use. 
     The above description is meant to be exemplary only, and one skilled in the art will recognize that changes may be made without departing from the concepts described. For example, as shown in  FIG. 6 , the groove  27 ′ may be provided between a pair of ridges  29 ′ extending across the wall  23 ′, rather than as a simple recess provided in the wall. As shown in  FIG. 7 , the groove  27 ″ may be provided between the base  21 ″ and a single protrusion  29 ″ above outer surface  25 ″. Other suitable configurations are also possible. Further, although groove is described, any suitable recess providing access for cutting the tying member may be used. Any suitable manner of providing access to an underside of the cable tie may be used, and groove and ridges are not required, per se. Any suitable shape and configuration of the saddle, and its base and walls, may be used. The particular nature of the tying member is not critical to the present concept. Although two walls providing a saddle are described, any suitable saddle/base shape and configuration may be used. For example, only one such wall may be provided. The “wall”(s) need not be a wall in a typical sense, but may be any suitable structure performing the function described herein. Still other modifications which fall within the scope of the present invention will be apparent to those skilled in the art, in light of a review of this disclosure, and the scope of the invention is therefore intended to be limited solely by the scope of the appended claims.
