DETAILED DESCRIPTION
As required, a schematic, exemplary embodiment of the present chain and chain tool are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the present disclosure, which may be embodied in various and/or alternative forms. Specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
Aspects, advantages and/or other features of exemplary embodiments of the invention will become apparent in view of the following detailed description, which discloses various non-limiting embodiments of the invention. In describing exemplary embodiments, specific terminology is employed for the sake of clarity. However, the embodiments are not intended to be limited to this specific terminology. It is to be understood that each specific member includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.
Exemplary embodiments may be adapted for many different purposes and are not intended to be limited to the specific exemplary purposes set forth herein. Other non-limiting examples of such embodiments are compositions that may be used, for example, for structural components. Those skilled in the art would be able to adapt the embodiments of the present disclosure, depending for example, on the intended use of the embodiment.
Chain members for moving and/or removing material are generally designed to be used in association with a chain tool. An exemplary embodiment of such a chain tool 100 is shown on FIG. 1. The exemplary embodiment chain tool 100 comprises a tool body 102 having a longitudinal axis X-X′, and a chain 104 arranged about the tool body 102 and linked therebetween.
The tool body 102 comprises a generally axi-symmetric envelope 106 extending about the longitudinal axis X-X′. The envelope 106 is disposed between generally radially-extending coaxially-aligned first and second ends 108, 110 (better seen on FIG. 2, hidden on FIG. 1) of the tool body 102. The tool body 102 further comprises a plurality of channels 112 circumferentially defined on the envelope 106.
The chain 104 comprises a plurality of chain members 114 consecutively linked therebetween. The chain members 114 are disposed on the plurality of channels 112 such that the chain members 114 are configured to be placed one following, or partially overlapping, each other, circumferentially, while advancing axially, i.e., to spiral circumferentially about the tool body 102, but not necessarily by equal increments, from the first end 108 to the second end 110.
The envelope of the tool body 102 describes a surface of revolution and any desirable profile may be used as its outline. In the exemplary embodiment of the tool body 102 as shown in FIG. 1, the plurality of channels 112 defined on the envelope 106 may comprise a plurality of ridge faces 116, and a plurality of groove faces 118. The ridge faces 116 and the groove faces 118 are arranged such that the ridge faces 116 and the groove faces 118 are parallel and alternately disposed with each other. Generally, a local ridge diameter RDL of a particular ridge face 116 is larger than a local groove diameter DGL of any groove face 118 adjacent to the particular ridge face 116.
The tool body 102 may be solid and/or hollow, as desired. Moreover, the tool body 102 may be monolithic (as shown in FIG. 1) and/or modular, as desired. FIG. 2 schematically illustrates a modular tool body 202. Since the modified embodiment of the tool body 202 is generally reminiscent of the exemplary embodiment of the tool body 102, components which are similar between the modified embodiment modular tool body 202 and the exemplary embodiment tool body 102 will be annotated by similar numbers increased by 100.
The modular tool body 202 comprises a bottom lid 220 and a top lid 222 distally located from each other along the longitudinal axis X-X′. The bottom lid 220 and the top lid 222 may serve as an outer face 224 and an inner face 226 of the modular tool body 202 respectively.
The modular tool body 202 may include alternating and interfitting ridge rings 228 and groove rings 230 disposed between the top lid 222 and the bottom lid 220. The ridge rings 228 and the groove rings 230 may axially extend between the bottom lid 220 and the top lid 222 along the longitudinal axis X-X′ of the tool body 202 to terminate at the top lid 222 of the tool body 202. Each of the ridge rings 228 may define a ridge face 216 thereon while each of the groove rings 230 may define a groove face 218 thereon.
FIG. 3 schematically illustrates a schematic modified embodiment of a chain tool 300. Since the modified embodiment of the tool body 302 is generally reminiscent of the exemplary embodiment of the chain tool 100, components which are similar between the modified embodiment chain tool 300 and the exemplary embodiment chain tool 100 will be annotated by similar numbers increased by 200.
The chain tool 300 has a tool body 302 having a generally frustoconical shape, with a bottom lid 320 (seen on the bottom left of FIG. 3) having a smaller bottom lid diameter RBL than a top lid diameter RTL of a top lid 322 of the tool body 302. Two parallel chains 304 are wrapped about the frustoconical tool body 302, starting adjacent the bottom lid 320 and spiraling away and circumferentially around the tool body 302 to terminate adjacent the top lid 322. Each chain 304 comprises a plurality of chain members 314 consecutively linked therebetween to form the chain 304.
Referring to FIGS. 4A and 4B, exemplary embodiments of tool bodies 402, 404 are illustrated. The tool body 402 of FIG. 4A illustrates a convex shape thereof while the tool body 404 of FIG. 4B illustrates a concave shape thereof. Although the convex and concave shapes are rendered to the tool bodies 402, 404 of FIGS. 4A and 5B respectively, it is to be noted that these shapes are merely exemplary in nature and hence, non-limiting of this disclosure. Any profile may be used to form and shape the tool bodies 402, 404 depending on specific requirements of various applications. Further, complex profiles such as but not limited to, curvilinear profiles and other, not always easily defined profiles may also be imparted to give form and shape to the tool bodies 402, 404.
Referring to FIGS. 5A and 5B, an alternative embodiment of the tool body 502 is illustrated. The channels 512 of the tool body 502 include alternating peaks 514 and troughs 516 linked by sloping sidewalls 518, 520 such that the alternating peaks and troughs 518, 520 are configured to define a generally triangular, generally trapezoidal, and/or generally sinusoidal, i.e., a sloped profile in a circumferential cross-section of the tool body 502, as best seen in FIG. 5B. A local peak diameter DP of a particular peak 514 is greater than a trough diameter DT of any adjacent trough 516.
Further, the channels 512 include a pitch P1 defined therebetween. The pitch P1 may be measured from one peak 514 to a successive or preceding peak 514. Alternatively, the pitch P1 may be measured as the distance from one trough 516 to a successive or preceding trough 516. In the embodiments of FIGS. 5A and 5B, the pitch P1 defined between adjacent channels 512 is equal i.e., the pitch P1 may be uniform across a length of the tool body 502. However, in an alternative embodiment of the tool body 504 as illustrated in FIG. 5C, a pitch P2 between adjacent channels 512 of the tool body 504 is unequal i.e., the pitch P2 between channels 512 across various sections of the tool body 504 may be non-uniform. Explanation to the equal and unequal pitches P1, P2 of the tool bodies 502, 504 may become clearer upon perusal of the disclosure hereinafter.

Each of the sixth embodiment chain member 1314 further comprises an outer side 1336 and an inner side 1338 laterally disposed to the first and second sidewalls 1332, 1334. The outer side 1336 and the inner side 1338 may extend into each other to further define a pair of peripheral sides 1340, 1342.
Any two subsequent sixth embodiment chain members 1314 are pivotally connected together by means of a connector 1352. In the sixth embodiment chain 1304, the connector 1352 is in a shape of a pin and a socket. On the first sidewall 1332 adjacent to the second sidewall 1334 and generally between the inner and outer sides 1338, 1336, there is disposed a socket 1374 while from the opposite second sidewall 1334, adjacent to the first sidewall 1332 and generally between the inner and outer sides 1338, 1336, there is disposed a pin 1360. The pin 1360 protrudes away from the second sidewall 1334 generally transversely thereto, while the socket 1374 is sunk into the chain member 1314 inside of the first sidewall 1332 and generally transversely thereto.
The outer side 1336 is provided with a sixth embodiment appendage 1346 upstanding therefrom. The sixth embodiment appendage 1346 is adapted to chip removing machinery. The inner side 1338 has a keel 1376 disposed thereon, merging with the inner side 1338 and jutting outwardly away therefrom so as to terminate at a keel face 1378. The keel 1376 has generally parallel and opposed first and second keel flanks 1380, 1382 merging with, and upstanding from, the inner side 1338 and interconnected by the keel face 1378 and generally opposed first and second keel walls 1384, 1386 extending therebetween generally transversely to the first and second keel flanks 1380, 1382. The keel 1376 is disposed generally about the center of the sixth embodiment chain member 1314 wherein the width TM6 is defined as the distance between the first and second sidewalls 1332, 1334, and has a keel thickness TK defined as the distance between the first and the second keel flanks 1380, 1382. The keel 1376 is flanked by generally similar rider faces 1388 of the inner side 1338. As best seen in FIG. 13C, each one of the plurality of chain members 1314 comprises a median plane M passing between the generally parallel and opposing first and second sidewalls 1332, 1334 and bisecting the sixth embodiment member thickness TM6.
In the sixth embodiment of the chain 1304, each sixth embodiment chain member 1314 has a rider depth DR defined as a distance from the center of the connector 1352 to the rider face 1388 of the sixth embodiment chain member 1314 and a keel depth DK defined as the distance from the center of the connector 1352 to the keel face 1378. In the sixth embodiment of the chain 1304, the keel depth DK is greater than the rider depth DR.
Attention is presently directed to FIG. 14. Sixth embodiment chain members 1314 are arrayed as a sixth embodiment chain 1304 by moving the first sidewall 1332 of a subsequent chain member 1314 towards the second sidewall 1334 (hidden in FIG. 14) of a preceding chain member 1314. The connector 1352 then connects the preceding and the subsequent chain members 1314 together, as is well known in the art. As the sixth embodiment chain members 1314 are chained together so as to form the sixth embodiment chain 1304, median planes M of subsequent sixth embodiment chain members 1314 are disposed parallel relative to each other. In the sixth embodiment of the chain 1304, adjacent median planes M are disposed parallel to each other displaced by a distance corresponding to the member thickness TM6.
Referring now to FIG. 15, there is shown a particular embodiment of a chain tool 1300 having a plurality of sixth embodiment chains 1304 wrapped therearound. The chain tool 1300 has a tool body 1302 having a generally cylindrical shape, with a bottom lid 1320 (seen on the bottom left of FIG. 15) and an opposing top lid (not shown) of the tool body 1302. Four generally parallel chains 1304 are wrapped around the tool body 1302, starting adjacent the bottom lid 1320 and spiraling away and circumferentially around the tool body 1302 so as to terminate adjacent the top lid (not shown). Each chain 1304 comprises a plurality of chain members 1314 consecutively attached so as to form the chain 1304.
The tool body 1302 comprises an envelope 1306 extending generally axially away from the bottom lid 1320 so as to terminate at the top lid (hidden in FIG. 15). The envelope 1306 describes a surface of revolution and any desirable curve may be used as its outline. The envelope 1306 of the tool body 1302 comprises parallel and alternating ridge faces 1316 and groove faces 1318 extending circumferentially around the envelope 1306. Each one of the groove faces 1318 extends between a first fence (hidden in FIG. 15) and a generally parallel and opposing second fence 1390, while a consecutive groove face 1318 extends between the second fence 1390 and a consecutive first fence (not shown).
Each one of the plurality of sixth embodiment chain members 1314 has its inner side 1338 touching the envelope 1306. The inner side 1338 of each chain member 1314 rides one of the ridge faces 1316 of the tool body 1302, with each one of the rider faces 1388 of each one of the inner sides 1338 touching consecutive ridge faces 1316, while each keel face 1378 is facing, but not necessarily abutting, the groove face 1318. A portion of each keel member 1348 is submerged below one of the ridge faces 1316 and is supported by the first fence (not shown) and the second fence 1390 of the envelope 1306. A ridge width WR and a groove width WG are generally similar to the member thickness TM6, while the groove depth GD of each groove face 1318, extending radially inwardly below the ridge face 1316, is generally the difference between the keel depth DK and the rider depth DR.
FIG. 16 shows a schematic general perspective representation of an alternative exemplary embodiment of a chain tool 1600 comprising an alternative tool body 1602 accommodating a plurality of a schematic, representative embodiment chain members 1614. Since the alternative embodiment of the chain 1604 as well as the alternative embodiment chain member 1614 are generally similar to the first embodiment of the chain 604 and the first embodiment of the chain member 614, components which are similar between the alternative embodiment chain 1604 and the first embodiment chain 604 will be annotated by similar numbers increased by 1000. Similarly, since the particular embodiment of the chain tool 1600 is generally similar to the exemplary embodiment of the chain tool 100, components which are similar between the modified particular embodiment chain tool 1600 and the exemplary embodiment chain tool 100 will be annotated by similar numbers increased by 1500.
The tool body 1602 comprises a generally axi-symmetric envelope 1606 extending about the longitudinal axis X-X′. The tool body 1602 further comprises a plurality of channels 1612 circumferentially defined on the envelope 1606. The envelope of the tool body 1602 describes a surface of revolution and any desirable profile may be used as its outline. In the exemplary embodiment of the tool body 1602 as shown in FIG. 1, the plurality of channels 1612 defined on the envelope 1606 may comprise a plurality of ridge faces 1616, and a plurality of groove faces 1618. The ridge faces 1616 and the groove faces 1618 are arranged such that the ridge faces 1616 and the groove faces 1618 are parallel and alternately disposed with each other.
The chain 1604 comprises a plurality of chain members 1614 consecutively linked therebetween. The chain members 1614 are disposed on the plurality of channels 1612 such that the chain members 1614 are configured to spiral circumferentially about the tool body 1602 from the first end 1608 to a second end (hidden in FIG. 16).
FIG. 17A to FIG. 17F show various forms and shapes conceivable of the seventh embodiment chain member 1614. Although some forms are illustrated herein, it is to be noted that these forms merely exemplary in nature and hence, non-limiting of this disclosure. A person having ordinary skill in the art may appreciate that various forms and configurations may be possible on the chain members 1614 for adaptation and use with the exemplary embodiment of the tool body 1602.
As best seen in FIGS. 17A to 17B, each of the chain members 1614 comprises a median plane M passing between the generally parallel and opposing first and second sidewalls 1632, 1634 and bisecting the sixth embodiment member thickness TM6. The inner side 1638 has at least one keel 1676 disposed thereon, merging with the inner side 1638 and jutting outwardly away therefrom so as to terminate at a plurality of keel faces 1678. The keels 1676 have generally parallel and opposed first and second keel flanks 1680, 1682 merging with, and upstanding from, the inner side 1638 and interconnected by the keel faces 1678. Particularly referring to FIG. 17A, a single keel 1676 extends away from the inner side 1638 of the chain member 1614. The keel 1676 is disposed transversely about the median plane M such that the median plane bisects the keel thickness TK. The keel 1676 is flanked by a pair of generally similar rider faces 1688 on the inner side 1638 of the chain member 1614. Particularly referring to FIG. 17B, two keels 1676 extend away from the inner side 1638 of the chain member 1614 with a single rider face 1688 defined therebetween on the inner side 1638 of the chain member 1614. Therefore, the rider face 1688 is disposed transversely about the median plane M such that the median plane bisects the rider thickness TR.
As best seen in FIGS. 17C to 17D, the inner side 1638 of the chain member 1614 has a plurality of keels 1676 disposed thereon, merging with the inner side 1638 and jutting outwardly away therefrom so as to terminate at a plurality of keel edges 1692. The keels 1676 have generally inclined and opposed first and second keel flanks 1680, 1682 merging with, and upstanding from, the inner side 1638 and interconnected by the keel edges 1692. Particularly referring to FIG. 17C, the keels 1676 are flanked by generally similar rider faces 1688 on the inner side 1638 of the chain member 1614. Particularly referring to FIG. 17D, two sets of keels 1676 extend away from the inner side 1638 such that a rider face 1688 is defined therebetween. Therefore, the rider face 1688 is disposed transversely about the median plane M such that the median plane bisects the rider thickness TR.
As best seen in FIGS. 17E and 17F, each of the chain members 1614 includes a basal face 1656. The basal face 1656 includes a first slant face 1658, and a second slant face 1660 disposed in opposing relation to the first slant face such that the first and second slant faces 1658, 1660 are configured to rest upon the sloping sidewalls 518, 520 of the tool body 502/504, as shown in FIG. 5B.
Each of the chain members 1614 further includes a keel edge 1692 defined at an intersection of the first and second slant faces 1658, 1660. The keel edge 1692 is configured to rest upon one of a peak 514 and a trough 516 of the tool body 502/504. More specifically, the keel edge 1692 of FIG. 17E is configured to rest upon the trough 516 of the tool body 502/504 while the slant faces 1658, 1660 abut the sloping sidewalls 518, 520 lying adjacent to the trough 516. Referring to FIG. 17F and FIG. 5B, it can be seen that a height HK of the keel edge 1692 from the basal face 1656 may correspond to a difference in depth DT of the trough 516 from the peak 514 measured along linear axis L-L′.
Similarly, with regards to the chain member 1614 of FIG. 17D, the keel edge 1692 may be configured to rest upon the peak 516 of the tool body 502/504 while the slant faces 1658, 1660 abut the sloping sidewalls 518, 520 lying adjacent to the peak 514. Referring to FIG. 17F and FIG. 5B, it can be seen that a depth DKE of the keel edge 1692 from an outer end 1617 of the basal face 1656 may correspond to a difference in height HP of the peak 514 from the trough 516 measured along linear axis L-L′.
Therefore, with reference to the embodiments shown in FIGS. 5A-5B, and FIGS. 17E-17F, it is evident that the generally triangular, generally trapezoidal, and/or generally sinusoidal, i.e., a sloped cross-section defined by the peaks 514 and troughs 516 on the circumference of the tool body 502, 504, may thus, confirm with a shape of the basal face 1656 as defined by the first and second slant faces 1658, 1660 of the chain member 1614. Although the tool bodies 502/504 with the generally triangular, generally trapezoidal, and/or generally sinusoidal, i.e., a sloped cross-section is disclosed for adaptation with the slant faces 1658, 1660 of the chain members 1614, it may be noted that the profile of the tool bodies 502/504 and the profile on the basal face 1656 of the chain members 1614 are non-limiting of this disclosure. A person having ordinary skill in the art may contemplate various forms and shapes known in the art to impart the required profiles to the tool bodies 502/504 and/or the chain members 1614.
FIG. 18 shows a schematic top perspective view of an exemplary seventh embodiment chain member 1614 adapted to be accommodated on the alternative embodiment of the chain tool 1600 shown on FIG. 16.

The seventh embodiment appendage 1646 is adapted for machining and removing chips from a material (not shown).
FIGS. 19, 20 and 21 show a schematic general representation of the alternative seventh embodiment chain member 1614. Since the alternative seventh embodiment chain member 1614 is generally similar to the first embodiment of the chain member 614, components which are similar between the seventh embodiment chain member 1614 and the first embodiment chain member 614 will be annotated by similar numbers increased by 1000.
As best shown in FIG. 19, each one of the plurality of seventh embodiment chain members 1614 comprises two generally parallel and opposing first and second sidewalls 1632, 1634 separated by a member thickness TM6. Each of the sixth embodiment chain member 1614 further comprises an outer side 1636 and an inner side 1638 laterally disposed to the first and second sidewalls 1632, 1634. The outer side 1636 and the inner side 1638 may extend into each other to further define a pair of peripheral sides 1640, 1642. Further, as shown in FIGS. 19 to 21 the first sidewall and the second sidewall 1632, 1634 of the seventh embodiment chain members 1614 are offset along the median plane M such that the peripheral sides 1640, 1642 exhibit a tiered configuration.
As best shown in FIG. 20 and FIG. 21, any two subsequent seventh embodiment chain members 1614 may be pivotally connected together by means of a connector (not shown). A pin (not shown) may be inserted through two matching and co-aligned pin through-holes or bores 1662 defined in two serially aligned chain members 1614, wherein each pin through-hole or bore 1662 is defined in one of the two neighboring chain members 1614.
