Abstract
ADJUSTABLE HOLDING DEVICE
ABSTRACT OF THE DISCLOSURE
Adjustable holding device for holding an item in a desired location relative to a surface, for example it can be used in a marine control system for holding an end of an outer sheath of a control cable adjacent a throttle control. To avoid the excessive number of brackets commonly required for holding items such as control cables, housings, and other light-weight accessories relative to an engine crankcase, gearbox, etc., the present invention provides a holding device that is universally adjustable in three planes to permit simple attachment to the crank case or gearbox with one portion of the device, and easy attachment at an opposite end to the item to be located. The device has inner and outer brackets for securing to the surface and to the item itself, with first, second and third members extending between the brackets. Lockable hinges connect adjacent members and brackets together rigidly, and yet provide adjustment to permit a wide range of inclination of the items.

(1) BACK~IROUND OF THE INVENTION
Field of the Invention The inventiorl relates to an adjustable holding device for holding an item in a desired location relative to a surface, and is particularlyadapted for, but not limited to, marine control applications for locating accessories, control cables, etc. relative to engine, gearbox components, etc.
Prior Art There is a wide variety of engine and gearbox combinations fitted in marine vessels, road vehicles~ etc., and there is a correspondingly wide variation of control system linkages and accessories for use with these combinations, most of which require a positive location relative to a Pixed surface. Usually a bracket supplied by the manufacturer is required to locate a particular item relative to a particular model of engine or gearbox, and if there is any change in the item, or if there is interference with adjacent 2D structure, the bracket supplied is unsuitabl0 and a custom made br~cket is required. If additional accessories are added later, often this custom made bracket itself becomes unsuitable and a second custom made bracket is required. FabricAting brackets on an "ad hoc" basis as above is time con-suming and expensive, and results mainly from the fact that most br~ckets 25 are not easily adjustable to accomodate non-standard combinations.
Manufacturers have attempted to keep pace with the ever increasing variety of, accessories and control systems by providing many brackets for specific purposes. Some major manufacturers supply hundreds of 30 different types oP brackets for specific applications and the supplying ~nd stocking of such brackets is expensive and time consuming. Furthermore, it is not unusu~l for a bracket supplied for a specific purpose to be inappropriatedue to a non-standard combination of adjacent equipment or accessories.

D:ETAILED DISCLOSUR13 30 Fi~ures 1 through 4 An adjustable holding device 10 according to the invention holds an item 11, l'or example a sheath ol' a control eable 12, in a desired location relative to a surface 13 oi' an engine crankcase 14. The device 10 has 2z~
(4) inner and outer brackets 16 and 17 bolted with rçspective b~lts 18 and 19 to thesurface 13, and to a clamp 20 around the cable sheath 12, respectively. For clarity, the clamp 20, the sheath 12 and bolts 19 are not shown in Figure 2.
The device nlso has first, second, third and fourth members designated 21, 22, S 23 and 24 respectively, in which t~e first ~md fourth memberx are generaUy similar to each other, and the second and third members are generally similar to each other as will be described.
._ . .
The inner bracket 16 has a securing portion or nange 27 having fastener openings 29 at one end to receive 10 one of the b~>lts 18, and an oval or fflstener opening 31 at an opposite end to rece~ve one of the bolts 18 to permit ad~ustment to accomodate openings in the surface 13. As saen in Figure 3, the inner bracket has a pinch bolt clamping means or structure 33 having an opening 34 defined by oppositely facin~ clamping portions 36 and 37 having aligned openings to 15 receive a pinch bolt 40. The first member 21 has a shaft 43 having a circular cross section which i9 complementary to the opening 34 of the clamping structure 33 so that the op~ning 34 receives the sha~e of the first portion and the pinch bolt can be used to reduce effeotiYe diameter of the opening 34 to hold the shaft therein. With the pinch bolt loosened, the shaft 43 can be 20 rotated relative to the inner bracket, and thus serves as a first hinge means46 having a first hinge axis 45 of rotation. Thus, the pinch bolt clamping structure 33 serves as a portion of a lo~kable first hinge means 46, and the shaft 43 serves as a complernentary portion of the first hinge means which can be locked relative to the inner bracket 16. Thus the first member has A
25 longitudinal axis coincident with the first aXiB 45 of rotation of the îirst hinge means to permit rotation OI the first member relative to the inner bracket.
~he first member also has an outer end having a boss 48 with a cylindrical opening 49 disposed centrally of the boss, the boss having an annular face Sl having engagine means thereon which are de~cribed in greater detail with 30 reference to Figures 5 and 6.
The second member 22 has a similar boss 54 having a similar cylindrical opening 55 disposed centrally thereof adiacent an inner end of the second member, the boss 54 having a similar annular face 56 and

The inner bracket 16 has a securing portion or nange 27 having fastener openings 29 at one end to receive 10 one of the b~>lts 18, and an oval or fflstener opening 31 at an opposite end to rece~ve one of the bolts 18 to permit ad~ustment to accomodate openings in the surface 13. As saen in Figure 3, the inner bracket has a pinch bolt clamping means or structure 33 having an opening 34 defined by oppositely facin~ clamping portions 36 and 37 having aligned openings to 15 receive a pinch bolt 40. The first member 21 has a shaft 43 having a circular cross section which i9 complementary to the opening 34 of the clamping structure 33 so that the op~ning 34 receives the sha~e of the first portion and the pinch bolt can be used to reduce effeotiYe diameter of the opening 34 to hold the shaft therein. With the pinch bolt loosened, the shaft 43 can be 20 rotated relative to the inner bracket, and thus serves as a first hinge means46 having a first hinge axis 45 of rotation. Thus, the pinch bolt clamping structure 33 serves as a portion of a lo~kable first hinge means 46, and the shaft 43 serves as a complernentary portion of the first hinge means which can be locked relative to the inner bracket 16. Thus the first member has A
25 longitudinal axis coincident with the first aXiB 45 of rotation of the îirst hinge means to permit rotation OI the first member relative to the inner bracket.
~he first member also has an outer end having a boss 48 with a cylindrical opening 49 disposed centrally of the boss, the boss having an annular face Sl having engagine means thereon which are de~cribed in greater detail with 30 reference to Figures 5 and 6.
The second member 22 has a similar boss 54 having a similar cylindrical opening 55 disposed centrally thereof adiacent an inner end of the second member, the boss 54 having a similar annular face 56 and
(5) complementary engaging means as will be described. A nut and bolt assembly 57 passes through the aligned openings 49 and 55 and clamps the outer end of the first member to the inner end of the second member, the engaging means of the adjacent faces 51 and 56 essentially preventing rotation between the 5 members when sufficient clamping force is applied. By loosening the nut and bolt assembly 57, the rnembers 21 and 22 can be rotated relative to each other, and can be seen to ~orm a portion of a second hinge means 61 having a second hinge axis 59. Thus, the second member has a complementary portion of the second hinge means for locking relative to the first member~ As best 10 seen in ~igure 2, the second hinge axis 59 is disposed normally to the first hinge axis 45.
The second member has at an outer end thereof a boss 63 which is a portion of a lockable third hinge means 64 which is generally 15 similar to the respective portion of the second hinge means. The third member 23 has a similar boss 66 which is a complementary portion of the third hinge means for lockirlg relative to the second member similarly to the second hinge means. The third hinge means 64 ha~ a bolt assembly 67 and a third hinge ~xis 68 which is parallel to the second hinge axis 59. The member 20 23 also has at an outer end thereof a boss 69 which is a portion of a lockable fourth hinge means 70 having similar engaging means. As previously stated, the fourth member 24 is generally similar to the first member 21 and has a cylindrical shaft 72 extending from a boss 73, the boss 73 having a central opening 74 therein to receive a bolt assembly 76 to form a complementary 25 portion of the fourth hinge means 7Q. The fourth hinge means 70 is lockable relative to the third member by the bolt assembly 76 and has a fourth hinge axis 78 parallel to the second and third axes of rotation.
The outer bracket 17 has a pinch bolt structure ~1 generally 30 similar to the pinch bolt structure 33 of the inner bracket and has an opening 82 complementary to the shaft 7a and a pinch bolt 83 to damp the structure to the shaft. Thus, it can be seen that the outer bracket 17 can be rotated about the shaft 72, which shaft and pineh bolt structure thus serve as a ` ~0;Z2~2
The second member has at an outer end thereof a boss 63 which is a portion of a lockable third hinge means 64 which is generally 15 similar to the respective portion of the second hinge means. The third member 23 has a similar boss 66 which is a complementary portion of the third hinge means for lockirlg relative to the second member similarly to the second hinge means. The third hinge means 64 ha~ a bolt assembly 67 and a third hinge ~xis 68 which is parallel to the second hinge axis 59. The member 20 23 also has at an outer end thereof a boss 69 which is a portion of a lockable fourth hinge means 70 having similar engaging means. As previously stated, the fourth member 24 is generally similar to the first member 21 and has a cylindrical shaft 72 extending from a boss 73, the boss 73 having a central opening 74 therein to receive a bolt assembly 76 to form a complementary 25 portion of the fourth hinge means 7Q. The fourth hinge means 70 is lockable relative to the third member by the bolt assembly 76 and has a fourth hinge axis 78 parallel to the second and third axes of rotation.
The outer bracket 17 has a pinch bolt structure ~1 generally 30 similar to the pinch bolt structure 33 of the inner bracket and has an opening 82 complementary to the shaft 7a and a pinch bolt 83 to damp the structure to the shaft. Thus, it can be seen that the outer bracket 17 can be rotated about the shaft 72, which shaft and pineh bolt structure thus serve as a ` ~0;Z2~2
(6) complementary portions of A lockable fifth hinge means 85 having a fifth hinge axis 86 which can be locked relative to the fourth member. The fourth member has a longitudinal axis coincident with the fifth hinge axis to permit rotation ~f the outer bracket relative to the fourth member. Similarly to the 5 inner bracket, the outer bracket has a securing portion or flange 87 havi-ng openings to receive the bolts 19 for clamping the clamp 20 arolmd the item 11 to be held by the device. In Figure 2, it can be seen that the fifth axis 86 is disposed within a plane which is parallel to a plane containing the first axis 45, both of the planes being normal to the seconc!~ third and fourth hinge axes.10 Clearly, the members could be arranged so that the axes 45 and 86 were coplanar, but this aspect is not necessary. Thus, the flrst and fifth hinge axesare disposecl normally to the second, third and fourth hinge means.
- The device has similar second, third and fourth hinge means~
and thus one hinge means interconnecting the first and seconcl members, namely the second hinge means 61, will be described in detail. The annular 20 face 56 of the boss 54 of the second member 22 has engaging means 91 which includes a plurality of radially disposed serrations 92 extending from positionsadjacent the opening 55. The serrations 92 have a relief, that is a height g4 between adjacent crests and troughs which is sufficient to cooperate with a similar and complementary relieved engaging means 95 of the boss 48 OI the 25 adjacent first member which pro-rides an interfitting relationship therewith.If the radially disposed serrations have an angular pitch 96 of flbout 5, it can be seen that the angular relationship between the first and second members can be varied approximately 5~ for each increment of relative rotation between the members. The second, third and ~ourth members have similar 30 engaging means adjacent openings at appropriate ends thereof, the engaging means augmenting gripping of an adjacent member secured at the respective bore to essentially prevent rotation between the members when the hinge means is locked.
(~) The engaging means are shown to be the radially disposed serra~ions provided on generally plane annular faces. Clearly, the faces cculd be conical, although this would tend to recluce the ease OI interchanging the components. Alternatively, means other than radially disposed serrations 5 could be used as engaging means to augment the gripping between engaged faces of the adjacent members.
C)PERATION
Mormally the inner bracket 16 would be first bolted to the surface 13, namely the en~ine crankcase, gearbox wall, ete., and the pinch bolt means 39 and 83 and the nut and bolt assemblies on the second, third and fourth hinge means would be loosened. The outer bracket 17 is then located in 15 its approximate location and the bolts of the first through fifth hinge meansare tightened slightly so as to locate the outer bracket 17 approximately where desired. The item to be located can then be clamped onto the outer bracket, eg. by the clamp 20, and the particular nuts and bolts of the hinge means can be adjusted as required to locate the item in the desired position, 20 at least within the 5 incremental adjustments permitted by the three hinge means. Clearly, as the first and fifth hinge means OI the pinch bolt structures do not have serrations, essentially continuous adjustment can be attained by rotatin~ about the first and fifth axes of rotation.
