The invention relates to a cable release system, an assembly for securing a cable sheath of a cable release system to a product, and a product having an assembly for securing a cable sheath of a cable release system. More specifically, the invention relates to a cable release system, assembly for securing a cable sheath of a cable release system to a product, and a product having an assembly for securing a cable sheath of a cable release system, wherein the product is a piece of motion furniture.
In certain pieces of motion furniture, a cable release system is utilized to allow the furniture to move from one position to another, for example, a recliner moving from an upright sitting position to a reclining position. Most cable release systems include a sheathed cable, an actuation member provided at one end of the sheathed cable, e.g., a handle, such that a user of the furniture can manipulate the cable release system to move the furniture from one position to another, a mounting bracket provided proximate to the other end of the sheathed cable, and means for moving the furniture from one position to another attached to the other end of the sheathed cable. The mounting bracket is typically provided in the interior of the furniture. One example of such a cable release system is a D-ring cable release system.
The sheath of the sheathed cable is connected to the mounting bracket, typically by sonic welding and/or gluing. The mounting bracket is then attached to the interior of the furniture by known means. Thus, the sheathed cable is fixed to the frame of the motion furniture. However, with these current methods of securing the sheath to the mounting bracket, several assembly and installation problems often occur.
One problem that has occurred is that once the mounting bracket is welded and/or glued, the mounting bracket is in a fixed position relative to the cable and sheath of the cable, and the frequent resultant twisting and kinking of the cable either caused the manufacturer of the motion furniture to remove and remount the entire cable release system, or caused the release system to malfunction in the field, resulting in inordinately expensive repair or recall.
Another problem that has occurred is that with welding and/or gluing of the mounting bracket, commonly occurring breakage or slippage due to imperfect weld and/or glue application resulted in costly repair and re-work, up to and including recall of the motion furniture.
There is also a problem with users of motion furniture having a problem with their cable fraying at the base of the actuation member as the motion of releasing the recliner mechanism in the furniture with the actuation member causes the actuation member to twist the cable. Over time, the cables will twist and kink and ultimately begin to fray.
Thus, there is a need for an improved structure of securing a cable sheath of a cable release system which overcomes the disadvantages of the prior art securing structures. The present invention provides such a structure of securing a cable sheath of a cable release system. Features and advantages of the present invention will become apparent upon a reading of the attached specification, in combination with a study of the drawings.
Briefly, and in accordance with the foregoing, the present invention provides five embodiments of an assembly for securing a cable sheath of a cable release system.
The first embodiment of the invention provides an assembly which includes a mounting bracket, preferably of one-piece construction, which is secured to a sheath of a sheathed cable by a retaining ring rather than by sonic welding or by gluing. Securing the bracket to the sheath by the retaining ring permits free rotation of the cable sheath. The retaining ring will not slide up or down accidentally on the sheath. The retaining ring secures the bracket in place, and also permits adjustment up and down to allow for variations in user assembly requirements.
The second embodiment of the invention provides an assembly which includes a plastic bracket made as one piece with a living hinge. The upper and lower sections of the bracket are connected by a living hinge which allows the upper section to be folded over to form the bracket. The upper section has a protruding tab that snaps into a recess in the lower section, which locks the two sections together. In assembly, the wire cable with two sections of sheathing are placed between the upper and low sections so that the wire cable is located in a groove and the sheathing sections are positioned on either side of the groove. When the upper and lower sections of the bracket are closed and locked together, the two sections of sheathing are held in place by protruding spikes located in the lower section of the bracket. When the bracket is mounted to the furniture using screws, the upper and lower section of the bracket are secured together and pressure is applied to the spikes holding the sheathing sections in place. This bracket eliminates additional parts and provides assembly of the bracket and cable without the use of tools.
The third embodiment of the invention provides an assembly which includes a one piece metal bracket having a U-shaped channel and protruding tab. The cable assembly with sheathing is inserted between the U-shaped channel and the tab. The tab applies pressure and helps hold the sheathing in place. There are also dimpled protruding spikes in the top of the channel that will bite into the outer surface of the sheathing to hold it in place.
The fourth embodiment of the invention provides an assembly which includes a one piece plastic bracket having a channel through the cylinder shaped section where the metal cable is inserted. There is a center hole through which the metal cable passes and then the sheathing is threaded into each end of the channel. The interior of the channel is threaded on either side of center hole and the sheathing is threaded on the outer diameter. Separating the sheathing into two sections and threaded ends prevents the sheathing from being pulled through the bracket when pulling force is applied.
The fifth embodiment of the invention provides an assembly which includes a one piece plastic bracket having a channel through the cylinder shaped section where the metal cable is inserted. There is a center hole through which the metal cable passes and then the sheathing is threaded at one end of the channel. The interior of the channel is threaded on one side of the center hole and the sheathing is threaded on the outer diameter. The threading prevents the sheathing from being pulled through the bracket when pulling force is applied. With the fifth embodiment, an alternative cable release system is also utilized which includes a metal clasp added to the wire cable to establish travel limits of the cable when pulled, a secondary sheathing added to protect fabric on the furniture from damage and protects the cable from friction causing fraying, and an actuation member which is free to rotate to eliminate twisting of the cable.
Each of the embodiments also effectively inhibits the cable and the cable sheath from twisting and/or kinking upon use of the cable release system.

The organization and manner of the structure and operation of the invention, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings wherein like reference numerals identify like elements in which:
While this invention may be susceptible to embodiment in different forms, there is shown in the drawings and will be described herein in detail, specific embodiments with the understanding that the present disclosure is to be considered an exemplification of the principles of the invention, and is not intended to limit the invention to that as illustrated and described herein.
As shown in
As illustrated in
Attention is now directed to the various embodiments of the invention. A first embodiment of an assembly 100 is shown in
Directing attention to the first embodiment of the invention, which is illustrated in
The mounting bracket 102 is preferably formed of a one-piece construction and is configured to have a first side surface 106, a second side surface 108, a top surface 110 which connects the first side surface 106 to the second side surface 108, and a bottom surface 112 which connects the first side surface 106 to the second side surface 108.
The first side surface 106 is planar and is preferably configured such that it is positioned against an interior, mounting surface (not shown) of the motion furniture 22. The second side surface 108 can be configured such that it is either planar or non-planar, but it is preferably configured such that it does not interfere with any part of the motion furniture 22 in which the cable release system 20 is provided.
The mounting bracket 102 has an aperture 114 which extends through the mounting bracket 102 from the top surface 110 to the bottom surface 112. The aperture 114 must be large enough such that the cable sheath 40 can be positioned therethrough, but must not be large enough such that the cable sheath 40 is allowed to freely move in a lateral position within the aperture 114 of the mounting bracket 102. The aperture 114 is preferably provided in a middle portion of the mounting bracket 102.
The mounting bracket 102 preferably has two apertures 116, 118 which extend through the mounting bracket 102 from the first side surface 106 to the second side surface 108. The aperture 116 is preferably provided on one side of the aperture 114 of the mounting bracket 102, while the aperture 118 is preferably provided on an opposite side of the aperture 114 of the mounting bracket 102. The apertures 116, 118 are provided in the mounting bracket 102 such that the mounting bracket 102 can be secured to the motion furniture 22. The first side surface 106 of the mounting bracket 102 is positioned against the interior mounting surface of the motion furniture 22 and fasteners (not shown) are inserted into the apertures 116, 118 from the second side surface 108 of the mounting bracket 102 and secured to the motion furniture 22. The mounting bracket 102 could also be secured to the motion furniture 22 by other known means.
The mounting bracket 102 includes a cavity 120 which extends into the mounting bracket 102 from the first side surface 106, but preferably does not extend through the mounting bracket 102 to the second side surface 104. The cavity 120 extends into the mounting bracket 102 and is in communication with the aperture 114 of the mounting bracket 102. The cavity 120 is wider than the aperture 114 such that an upper shoulder 122 is provided by the cavity 120 and such that a lower shoulder 124 is provided by the cavity 120. The purpose for the cavity 120 and the upper and lower shoulders 122, 124 will be discussed further herein.
The mounting bracket 102 may also have further cavities and apertures provided therein or therethrough in order to minimize the amount of material used to form the mounting bracket 102, thus reducing the cost of manufacture of the mounting bracket 102.
The retaining ring 104 is preferably an open-ended spring steel ring which includes a middle section 126, a pair of enlarged end sections 128, and a pair of intermediate sections 130 which interconnect the end sections 128 with the middle section 126. The enlarged end sections 128 are spaced apart from one another to define an opening 132 located opposite the middle section 126. When the retaining ring 104 is in its normal position, the opening 132 is smaller between the enlarged end sections 128 than between the intermediate sections 130. The retaining ring 104 can also be formed in the manner illustrated and described in U.S. Pat. No. 4,886,408.
In operation, the cable sheath 40 is inserted through the aperture 114 of the mounting bracket 102 such that the cable sheath 40 is accessible through the cavity 120 from the first side surface 106 of the mounting bracket 102. The retaining ring 104 is then inserted into the cavity 120 from the first side surface 106 of the mounting bracket 102 such that the enlarged end sections 128 of the retaining ring 104 face the second side surface 108 of the mounting bracket 102. The enlarged end sections 128 are moved against the cable sheath 40 within the cavity 120 between the upper shoulder 122 and the lower shoulder 124. The enlarged end sections 128 are thus moved away from one another and the cable sheath 40 is moved into the opening 132 of the retaining ring 104. The enlarged end sections 128 are then secured to the cable sheath 40.
The retaining ring 104 is thus secured to the cable sheath 40 within the cavity 120 of the mounting bracket 102 between the upper shoulder 122 and the lower shoulder 122, thus completing the assembly 100. The retaining ring 104 permits free rotation of the cable sheath 40. The retaining ring 104 will not slide up or down accidentally on the cable sheath 40 as the retaining ring 104 is prevented from moving too far up or down on the cable sheath 40 because of the confines of the cavity 120 defined by the upper shoulder 122 and the lower shoulder 124. Thus, the retaining ring 104 of the assembly 100 secures the cable sheath 40 in place relative to the mounting bracket 102, but permits adjustment up and down to allow for variations in user assembly requirements of the motion furniture 22.
The retaining ring 104 is adjustable and removable. The retaining ring 104 secures the mounting bracket 102 in place vertically, permitting desirable free rotation of the mounting bracket 102 horizontally to prevent kinking or twisting of the cable sheath 40. The securement of the mounting bracket 102 to the cable sheath 40 by the retaining ring 104 eliminates the frequently occurring and costly problems caused by slippage of the bracket resulting from broken or inadequate weld/glue applications. The easy removability of the retaining ring 104 enables the mounting bracket 102 to be readjusted before or after assembly, allowing for variations in a manufacturer's final assembly requirements. The retaining ring 104 permits the end user to install the assembly 100 at any vertical point on the cable sheath 40 in order to provide greater flexibility than was heretofore available, permitting greater flexibility for the furniture retailer with minimal stock-keeping units needed.

The fifth portion 446 is cylindrical in configuration and the wall 456 of the fifth portion 446 of the aperture 436 is preferably at least partially threaded. The fifth portion 446 has a diameter which is greater than the diameter of the fourth portion 444, and generally equivalent to a diameter of the third portion 442, such that a shoulder 458 is provided between the fourth and fifth portions 444, 446. The sixth portion 448 extends from the fifth portion 446 toward the seventh side edge 420. The sixth portion 448 is generally frustoconical in configuration such that a diameter of the sixth portion 448 distal from the fifth portion 446 is larger than a diameter of the sixth portion 448 proximate to the fifth portion 446. The seventh portion 450 extends from the sixth portion 448 to the seventh side edge 420. The seventh portion 450 is generally frustoconical in configuration such that a diameter of the seventh portion 450 at the seventh side edge 420 is larger than a diameter of the seventh portion 450 at the connection of the sixth and seventh portions 448, 450.

In operation, as best illustrated in
The flexible cable 30 of the cable release system 20 is inserted through the aperture 436 of the mounting bracket 402. The flexible cable 30 is then inserted through the two cable sheaths 40 and the other components of the cable release system 20, as required, are secured to either the flexible cable 30 or the cable sheaths 40.
One of the two cable sheaths 40 is then inserted into the aperture 436 through the first side edge 408 of the mounting bracket 402 and is threaded into the third portion 442 of the aperture 436 by the threading on the outer surface 464 of the cable sheath 40 and by the threading on the wall 452 of the third portion 442. The cable sheath 40 is prevented from being threaded too far into the aperture 436 by the shoulder 454 provided between the third and fourth portions 442, 444, as the cable sheath 40 has an outer diameter which is larger than the diameter of the fourth portion 444. The frustoconical first and second portions 438, 440 of the aperture 436 are provided to assist in inserting the cable sheath 40 into the aperture 436 for threading within the third portion 442 of the aperture 436.
Likewise, the other one of the two cable sheaths 40 is then inserted into the aperture 436 through the seventh side edge 420 of the mounting bracket 402 and is threaded into the fifth portion 446 of the aperture 436 by the threading on the outer surface 464 of the cable sheath 40 and by the threading on the wall 456 of the fifth portion 446. The cable sheath 40 is prevented from being threaded too far into the aperture 436 by the shoulder 458 provided between the fourth and fifth portions 444, 446, as the cable sheath 40 has an outer diameter which is larger than the diameter of the fourth portion 444. The frustoconical sixth and seventh portions 448, 450 of the aperture 436 are provided to assist in inserting the cable sheath 40 into the aperture 436 for threading within the fifth portion 446 of the aperture 436.
The threaded engagement between the outer surfaces 464 of the cable sheaths 40 and the walls 452, 456 of the third and fifth portions 442, 446, respectively, of the aperture 436 of the mounting bracket 402 secures the cable sheaths 40 within the mounting bracket 402 such that the cable sheaths 40 are prevented from being pulled through the mounting bracket 402 when a pulling force is applied thereto. The securement of the cable sheaths 40 to the mounting bracket 402 also assists in inhibiting the cable sheaths 40 and the cable 30 from twisting and/or kinking during use.
Fastening members (not shown), such as screws, can then be inserted through the apertures 460, 462 in order to mount/secure the mounting bracket 402 to the motion furniture 22.

In use, the assembly 500 is secured to the sheath 40 of an alternative cable release system 20′ which is illustrated in
The actuation member 38′ is best illustrated in
The clasp member 42′ is preferably a hollow cylindrical member which is formed of metal.
The secondary sheath 44′ is preferably a hollow cylindrical member which is formed a relatively strong plastic.
The enlarged spherical member 45′ is preferably formed of metal and is fixedly secured to the second end 34 of the flexible cable 30.
In operation, the flexible cable 30, including the enlarged spherical member 45′, is first inserted through the second portion 54b′ of the opening 54′, and then through the first portion 54a′ of the opening 54′, such that the enlarged spherical member 45′ is positioned within the second portion 54b′ of the opening 54′, and prevented from going into the first portion 54a′ of the opening 54′ by the shoulder 58′, such that the first end 32 of the flexible cable 30 is provided outside of the actuation member 38′.
Thereafter, the first end 32 of the flexible cable 30 is inserted through the hollow secondary sheath 44′, until the secondary sheath 44′ is moved into the first portion 54a′ of the opening 54′.
Thereafter, the first end 32 of the flexible cable 30 is inserted through the hollow clasp member 42′, until the clasp member 42′ is moved generally against the secondary sheath 44′. The hollow clasp member 42′ is then crimped around the flexible cable 30 such that the secondary sheath 44′ is secured between the hollow clasp member 42′ and the enlarged spherical member 45′. It should be noted that the clasp member 42′ could either be clamped into position around the flexible cable 30 to either allow a little movement of the secondary sheath 44′ between the clasp member 42′ and the enlarged spherical member 45′, or such that no movement of the secondary sheath 44′ is allowed for between the clasp member 42′ and the enlarged spherical member 45′.
Thereafter, the first end 32 of the flexible cable 30 is inserted through the aperture 542 of the mounting bracket 502 from the sixth portion 554 to the first portion 544.
Thereafter, the first end 32 of the flexible cable 30 is inserted through the cable sheath 40, having an outer surface 564 at an end 566 thereof which is threaded. The threaded outer surface 564 at the end 566 of the cable sheath 40 is then inserted into the aperture 542 of the mounting bracket 502 and is threaded into the threaded wall 556 of the third portion 548 of the aperture 542.
The threaded engagement between the outer surface 564 of the cable sheath 40 and the wall 556 of the third portion 548 of the aperture 542 of the mounting bracket 502 secures the cable sheath 40 within the mounting bracket 502 such that the cable sheath 40 is prevented from being pulled through the mounting bracket 502 when a pulling force is applied thereto. The securement of the cable sheath 40 to the mounting bracket 502 also assists in inhibiting the cable sheath 40 and the cable 30 from twisting and/or kinking during use.
Fastening members (not shown), such as screws, can then be inserted through the apertures 534, 540 in order to mount/secure the mounting bracket 502 to the motion furniture 22.
The construction of the assembly 500 in conjunction with the alternative cable release system 20′ provides a number of benefits. For example, it has been a known problem that users of motion furniture have had problems with the flexible cable fraying at the base of the actuation member, such as the D-ring. The motion of releasing the actuation member caused the actuation member to twist the flexible cable. Over time the flexible cable would twist and kink and ultimately begin to fray.
The assembly 500 in conjunction with the alternative cable release system 20′ addresses this problem. As the flexible cable 30 is secured to the actuation member 38′ by the enlarged spherical member 45′ being trapped within the second portion 54b of the opening 54′ of the extension portion 50′ of the actuation member 38′, the actuation member 38′ is able to freely rotate about the enlarged spherical member 45′ and, thus, the flexible cable 30′ secured thereto. The free rotation of the actuation member 38′ eliminates twisting of the flexible cable. The construction of the actuation member 38′ also does not require for extra parts and assembly for securing the flexible cable 30 to the actuation member 38′.
The secondary sheathing 44′ protects the fabric provided on the motion furniture from damage caused by the flexible cable 30 repeatedly being moved back and forth against it, and thus, also protects the flexible cable 30 from friction against the fabric of the motion furniture which causes fraying.
The clasp member 42′ is provided to position the secondary sheathing 44′ between the clasp member 42′ and the enlarged spherical member 45′, and further to establish travel limits of the flexible cable 30 when the actuation member 38′ is pulled.
An alternative configuration of the actuation member 38′ is provided in
As best illustrated in
The first, lower section 60″ has a partial, half groove 66″ formed at the extension end 52″ and a gap 68″ provided therein which is open to the half groove 66″, but which is larger than the groove 66″ such that a shoulder 70″ is formed between the groove 66″ and the gap 68″. To one side of the gap 68″, an aperture 72″ is provided through the first, lower section 60″. To the opposite side of the gap 68″, an aperture 74″ is provided through the first, lower section 60″. The living hinge 64″ is provided proximate to the aperture 74″ and distal to the aperture 72″.
The second, upper section 62″ has a partial, half groove 76″ formed at the extension end 52″ and a gap 78″ provided therein which is open to the half groove 76″, but which is larger than the groove 78″ such that a shoulder 80″ is formed between the groove 76″ and the gap 78″. To one side of the gap 78″, an locking tab member 82″ is provided which extends from the second, upper section 62″. To the opposite side of the gap 78″, an aperture 84″ is provided through the second, upper section 62″. The living hinge 64″ is provided proximate to the aperture 84″ and distal to the locking tab member 82″.
In operation, the enlarged spherical member 45′ is positioned within the gap 68″ such that the flexible cable 30 extends through the groove 66″ of the first, lower section 60″. The second, upper section 62″ is then folded over the first, lower section 60″ about the living hinge 64″. By folding the second, upper section 62″ over the first, lower section 60″, the following occurs: (1) the aperture 84″ is aligned with the aperture 74″ to form an aperture 86″ of the extension member 50″, as illustrated in
Thereafter, the formation of the alternative cable release assembly 20′ is identical to that previously described. The use of the alternative actuation member 38″ provides the same benefits as does the actuation member 38′, but has a different structure.
It should be noted that the configurations of the mounting brackets 102, 202, 302, 402, 502 and the actuation members 38, 38′, 38″ described are the preferred configurations, but that other alternative configurations of the mounting brackets 102, 202, 302, 402, 502 and the actuation members 38, 38′, 38″ are considered to be within the scope of the invention as described, illustrated and claimed herein.
The configuration of the mounting brackets 102, 202, 302, 402, 502 substantially prevents the cable sheath(s) 40 from moving within the openings/channels/apertures of the mounting brackets 102, 202, 302, 402, 502.
While preferred embodiments of the present invention are shown and described, it is envisioned that those skilled in the art may devise various modifications of the present invention without departing from the spirit and scope of the appended claims.
