Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of and priority to Korean Patent Application No. 10-2019-0026161 filed on Mar. 7, 2019 and Korean Patent Application No. 10-2019-0080016 filed on Jul. 3, 2019, which are herein incorporated by reference in its entirety. 
     TECHNICAL FIELD 
     The present invention relates to a belt member and a cable guiding device comprising the same. In detail, a belt member and a cable guiding device comprising the same can firmly protect and guide cables that can be in a straight and/or bended posture. 
     TECHNICAL BACKGROUND 
     The present invention is related to a cable guiding device that protects and guides flexible cables or hoses which may be electric cables, optical fiber cables, fluid supply hoses (hereinafter referred to as a “cable” or “cables”). The cables are used for machine tools, electronic devices, industrial robots, transportation machines and others, to feed electricity, fluid, air and other things to those moving machines or to a moving part of the machines. 
     If cables are to be connected to a mobile body of a machine tool, a civil engineering machine, or a conveying system, the cables may be damaged by causing excessive torsion or tension when they are moved. Under those circumstances, a cable protection and guiding device is used to support and guide such cables. 
     Prior art cable protection and guide apparatuses are known in which conductors, conduits for conveying gas, and supporting members include continuous material strips. The continuous material strips include a series of non-interlocked action-limited solid bodies sealed within a plurality of channels and disposed therein in parallel (e.g. PATENT DOCUMENTS #1) for example. 
     In the prior art, a flexible material composing the supporting member is stainless steel or a leaf spring, the device is difficult to install within a limited space because the supporting member is unable to maintain an accurate bending radius during bending. During bending, its bending radius increases and it may contact an obstacle in the vicinity of itself. In particular, when stainless steel is used as the flexible member, the apparatus may breakdown and rupture as a result of fatigue and become unusable. 
     Because the flexible material composing the supporting member is stainless steel or made form a leaf spring, which cannot be easily cut and connected, in order to change the length of the supporting member, the supporting member itself has to be replaced which causes waste of supporting members. 
     The prior art device may cause resonance and destabilize operations such as operation between bending and straight postures because its twisting rigidity is low when it is bent. 
     The prior art device requires much burden and time for its production and cannot be mass-produced because pieces formed of resin must be injection-molded one at a time to the stainless steel or leaf spring. 
     In the prior art, while a jacket component is retained by a pair of upper and lower clamping means to handle the conductors, conduits and Supporting members. When members are assembled to a machine frame-side stationary end area or a machine movable=side moving end area with a pair of upper and lower clamping means, the Supporting members are dislocated from the jacket component or abruptly fall out of the jacket component becoming unable to securely guide the conductors or the conduits. The prior art apparatus is difficult to assemble and disassemble because the conductors, the conduits and the Supporting members cannot be removed out of a machine frame-side stationary end area or a machine movable-side moving end area separately during maintenance such as replacing or repairing a cable from old to new, large to small or dissimilar functions.

     Further, in the present invention, the #1 space  14   a  means the area opposite to the location at which the protrusion area is formed; in further details, since protrusion areas may be formed on the bottom surface of the belt member #1 unit  10   a  and the bottom surface of the belt member #2 unit  10   b,  thus the #1 space  14   a  can mean the area opposite to that at which the protrusion area is formed, which starts from the top surface of the belt member #1 unit  10   a  and the top surface the belt member #2 unit  10   b,  following the exterior of the belt member #1 unit  10   a  bod and the exterior of the belt member #2 unit  10   b  body, all the way to the #1 connection point  13   a.    
     Further, with reference to belt member #2 unit  10   b  and belt member #3 unit  10   c,  #2 connection point  13   b  at which the belt member #2 unit  10   b  and the belt member #3 unit  10   c  are adjoined; and #2 space  14   b  above the #2 connection point  13   b  are included. 
     Definitions of the #2 connection point  13   b  and the #2 space  14   b  are given above, thus no further explanation will be provided.

     With reference to  FIG. 14 a    and  FIG. 14 b   , in the present invention, layer #1 belt member  1000 - 1  and layer #2 belt member  1000 - 2  may be stacked to conform a stacked belt member  2000 . 
     Where the layer #1 belt member  1000 - 1  may comprise multiple belt member units  10   a ,  10   b,    10   c,  . . . , and the layer #2 belt member  1000 - 2  may comprise multiple belt member units  10   a ′,  10   b ′,  10   c′, . . . .    
     Further, the layer #2 belt member  1000 - 2  may be located above the layer #1 belt member  1000 - 1 , whilst the layer #2 belt member  1000 - 2  shall be misaligned by a specific displacement from the layer #1 belt member  1000 - 2 . 
     In particular, as described above, the layer #1 belt member  1000 - 1  comprises multiple spaces  FIG. 13 a   , #1 space  14   a,  #2 space  14   b,  etc. formed by the assembly of multiple belt member units; and the layer #2 belt member  1000 - 2  comprises multiple protrusion areas formed on each multiple belt member units  10   a ′,  10   b ′,  10   c′, . . . .    
     Where, the layer #2 belt member  1000 - 2  shall be arranged above the layer #1 belt member  1000 - 1  in a manner that allows each multiple protrusion area of the layer #2 belt member  1000 - 2  to be inserted to each multiple space of the layer #1 belt member  1000 - 1 . 
     For instance, assuming that the layer #1 belt member  1000 - 1  comprises #1 space and #2 space, etc., while the layer #2 belt member  1000 - 2  comprises #1 protrusion area, #2 protrusion area, and #3 protrusion area, etc., the layer #2 belt member  1000 - 2  shall be located above the layer #1 belt member  1000 - 1  at an alignment where the #2 protrusion area is inserted in the #1 space, and the #3 protrusion area is inserted in the #2 space.

     In particular, the #1 protrusion area  62  comprises: #1-1 slope  62   a  from #1-1 predetermined position of the #1-1 body  61   a  continued to #1-1 direction of the #1-1 body  61   a ; #1-2 slope  62   b  from #1-2 predetermined position of the #1-2 body  61   b  continued to #1-2 direction of the #1-2 body  61   b;  and #1 connection point  62   c  at which the #1-1 slope  62   a  and the #1-2 slope  62   b  meets. 
     Further, #1 belt member sub-unit  60  of the present invention comprises #1 space  63  between #1-1 belt member unit  60   a  and the #1-2 belt member unit  60   b.    
     Details of such configuration are identical to  FIG. 19 a    and  FIG. 19 b   , and thus no further explanation will be provided. 
     Further, as described above, in the present invention, layer #1 belt member  7000 - 1  and layer #2 belt member  7000 - 2  may be stacked together to conform a stacked belt member  7000 . For the convenience of explanation, detail numerals are omitted for the configuration of the layer #2 belt member  7000 - 2 , whereas numerics provided for the layer #1 belt member  7000 - 1  can be referred for detail numerics of the configuration of the layer #2 belt member  7000 - 2 . 
     In particular, the #2 belt member  7000 - 1  comprises #2 belt member sub-unit no numeral, where the #2 belt member sub-unit no numeral comprises #2-1 belt member unit no numeral and #2-2 belt member unit no numeral located immediately adjacent to the #2-1 belt member unit no numeral. 
     Where, the #2-1 belt member unit no numeral comprises a tubular #2-1 body no numeral, and the #2-2 belt member unit no numeral comprises a tubular #2-2 body no numeral. 
     Where, the #2 belt member sub-unit no numeral comprises #2 protrusion area no numeral wherein one side is adjoined with the #2-1 body no numeral and the other side is adjoined with the #2-2 body no numeral. 
     In particular, the #2 protrusion area no numeral comprises: #2-1 slope no numeral from #2-1 predetermined position of the #2-1 body no numeral continued to #2-1 direction of the #2-1 body no numeral; #2-2 slope no numeral from #2-2 predetermined position of the #2-2 body no numeral continued to #2-2 direction of the #2-2 body no numeral; and #2 connection point no numeral at which the #2-1 slope no numeral and the #2-2 slope no numeral meets. 
     Provided that, the present invention does not limit the presence of the #2 protrusion area of the #2 belt member sub-unit. 
     Thus, above the layer #2 belt member comprising the #2 belt member sub-unit, for instance if layer #3 belt member is present, the #2 belt member sub-unit of the layer #2 belt member shall comprise #2 protrusion area, yet, if the layer #2 belt member is on the top of other belt members, the #2 belt member sub-unit does not have to comprise the #2 protrusion area. 
     Further, #2 belt member sub-unit no numeral of the present invention comprises #2 space no numeral between #2-1 belt member unit no numeral and the #2-2 belt member unit no numeral. 
     As explained above, numerics provided for the layer #1 belt member  7000 - 1  can be referred for detail numerics of the configuration of the layer #2 belt member  7000 - 2 . 
     Where, the layer #2 belt member  7000 - 2  shall be located above the layer #1 belt member  7000 - 1 , whilst the layer #2 belt member  7000 - 2  shall be accurately aligned with no displacement from the layer #1 belt member  7000 - 1 . 
     In particular, by placing #1 protrusion area  62  of the #1 belt member sub-unit  60  of the layer #1 belt member  7000 - 1  in #2 space no numeral of the #2 belt member sub-unit no numeral of the layer #2 belt member  7000 - 2 , the layer #2 belt member  7000 - 2  is located above the layer #1 belt member  7000 - 1 , whilst the layer #2 belt member  7000 - 2  is accurately aligned with no displacement from the layer #1 belt member  7000 - 1 . 
     Thus, in the present invention, by arranging the layer #2 belt member  7000 - 2  above the layer #1 belt member  7000 - 1 , whilst the layer #2 belt member  7000 - 2  is accurately aligned with no displacement from the layer #1 belt member  7000 - 1 , the layer #2 belt member and the layer #1 belt member can be firmly prevented from falling off from each other. 
     The configuration of the belt member of the present invention was explained above, with the structure of belt member sub-units of the present invention, as described for  FIG. 19 a   ,  FIG. 19 b   ,  FIG. 20 a    and  FIG. 20   b.    
     Where belt member sub-units illustrated in  FIG. 19 a    and  FIG. 19 b    may be defined as described below. 
     In particular, when belt members are stacked in  2  layers, i.e. when layer #2 belt member is stacked on top of layer #1 belt member, the protrusion area  62  of belt member sub-unit illustrated in  FIG. 19 a    and  FIG. 19 b    can have a role in preventing the layer #2 belt member and the layer #1 belt from falling off from each other. 
     However, additional to the aforesaid role, the protrusion area  62  of belt member sub-unit illustrated in  FIG. 19 a    and  FIG. 19 b    may have the same role as tubular #1 body  61   a  of the #1 belt member unit  60   a  and tubular #2 body  61   b  of the #2 belt member unit  60   b.    
     Thus, the tubular #1 body  61   a  and the tubular #2 body  61   b  accommodates cables flexible cables and hoses including electric cables, optical fiber cables, fluid supply hoses, where the protrusion area  62  of belt member sub-unit illustrated in  FIG. 19 a    and  FIG. 19 b   , can have an additional role, aside from its role to prevent the layer #2 belt member and the layer #1 belt member from falling off from each other, that is identical to the roles of the tubular #1 body  61   a  and the tubular #2 body  61   b,  which is accommodating cables. 
     For instance, with a belt member sub-unit as illustrated in  FIG. 19 a   , assuming the tubular #1 body  61   a  and the tubular #2 body each accommodates one cable, the protrusion area  62  of belt member sub-unit can accommodate an additional cable, where a belt member sub-unit, as illustrated in  FIG. 19 a    can accommodate a total number of 3 cables. 
     In particular, for instance, assuming a total number of three cables have to be accommodated, in general, for a belt member sub-unit as illustrated in  FIG. 19 a   , the tubular #1 body  61   a  and the tubular #2 body  61   b  can each accommodate one cable, thus to accommodate a third cable, another belt member sub-unit has to be stacked. 
     However, assuming a total number of three cables have to be accommodated, in the present invention, for a belt member sub-unit as illustrated in  FIG. 19 a   , the tubular #1 body  61   a  and the tubular #2 body  61   b  can each accommodate one cable, and the protrusion area  62  of belt member sub-unit can accommodate the third cable, thus, the intended cables can be accommodated without stacking an additional belt member sub-unit. 
     Where, as described above, the following effects may be achieved by accommodating a cable in the protrusion area  62  of the belt member sub-unit. 
       FIG. 21 a    and  FIG. 21 b    are actual photographs of a protrusion area of layer #1 belt member shown in  FIG. 20 a    and  FIG. 20 b   , with no cable inserted, in a bending posture; and  FIG. 22 a    and  FIG. 22 b    are actual photographs of a protrusion area of layer #1 belt member shown in  FIG. 20 a    and  FIG. 20 b   , with cables inserted, in a bending posture. 
     For the convenience of description, the layer #1 belt member shall be indicated as belt member. 
     With reference to  FIG. 21 a    and  FIG. 21 b   , where the belt member is bended without accommodating a cable in the protrusion area of belt member, the protrusion are is ruffled at the bending, thus the protrusion area is not likely to perform its role, at the bended areas, of preventing the layer #2 belt member and the layer #1 belt member from falling off from each other. 
     On the contrary, with reference to  FIG. 22 a    and  FIG. 22 b    where the belt member is bended while accommodating a cable in the protrusion area of belt member, the cable that is inserted in the protrusion area supports the protrusion area when bent, thus, the protrusion area can maintain its posture even when bent, and can perform its role to prevent the layer #2 belt member and the layer #1 belt member from falling off from each other. 
     Accordingly, by inserting a cable to the protrusion area, the protrusion area can perform the additional role to accommodate the cable, the cable supports the protrusion area allowing the protrusion area to maintain its posture even when bent, thus, the protrusion area can perform its role to prevent the layer #2 belt member and the layer #1 belt member from falling off from each other. 
     In accordance with the above description, belt member sub-units illustrated in  FIG. 19 a    and  FIG. 19 b    can be defined as below. 
     Provided that, except for the following descriptions,  FIG. 19 a   ,  FIG. 19 b   ,  FIG. 20 a    and  FIG. 20 b    may be referred for the following definition of belt member sub-unit. 
     As described above,  FIG. 19 a    is a cross-sectional drawing of the belt member sub-unit  60  of the present invention; and  FIG. 19 b    is a perspective view of the belt member sub-unit  60  of the present invention. 
     With reference to  FIG. 19 a    and  FIG. 19 b   , belt member sub-unit  60  of the present invention comprises: #1 belt member unit  60   a;  and #2 belt member unit  60   b  immediately adjacent to the #1 belt member unit  60   a.    
     In the present invention, the configuration in which the #1 belt member unit  60   a  and the #2 belt member unit  60   b  are immediately adjoined, shall be referred to as belt member sub-unit. 
     In particular, as described above, the #1 belt member unit  60   a  comprises a tubular #1 body  61   a,  and the #2 belt member unit  60   b  comprises a tubular #2 body  61   b.    
     Layer #1 body can be defined as, in the present invention, the tubular #1 body  61   a  of the #1 belt member unit  60   a  and the tubular #2 body  61   b  of the #2 belt member unit  60   b.    
     Thus, the belt member sub-unit  60  can be defined as, in the present invention, the layer #1 body comprising the tubular #1 body  61   a  and the tubular #2 body  61   b  located immediately adjacent to the #1 body  61   a.    
     Further, and as described above, the belt member sub-unit  60  comprises a protrusion area  62  wherein one side is adjoined with the #1 body  61   a  and the other side is adjoined with the #2 body  62   b.    
     In the present invention, the protrusion area can accommodate cables thus, if the protrusion area is defined as the tubular #1 body  61   a  and the tubular #2 body  61   b,  the protrusion area  62  can be defined as the layer #2 body located at #1 area of the layer #1 body, comprising the tubular protrusion body  62  located between the #1 body  61   a  and the #2 body  61   b.    
     Based on the above definition, in the present invention, the belt member sub-unit  60  can be defined as the combination comprising: layer #1 body that comprises a tubular #1 body  61   a  and a tubular #2 body  61   b  immediately adjacent to the #1 body  61   a;  and layer #2 body located at #1 area of the layer #1 body, that comprises the tubular protrusion area  62  in between the #1 body  61   a  and the #2 body  61   b.    
     As illustrated in drawings, the #1 area can be the top of the #1 body, however, conversely, the #1 area can be the bottom of the #1 body, thus, the present invention does not limit the meaning of top and bottom. 
     Where, in the present invention, the #1 body  61   a  can accommodate #1 cable, the #2 body  61   b  can accommodate #2 cable, and especially for the present invention, the protrusion area  62  can accommodate #3 cable. 
     Thus, as described above, by inserting a cable to the protrusion area  62 , the protrusion area can perform the additional role to accommodate the cable, the cable supports the protrusion area allowing the protrusion area to maintain its posture even when bent, thus, the protrusion area can perform its role to prevent the layer #2 belt member and the layer #1 belt member from falling off from each other. 
     With further reference to  FIG. 19 a    and  FIG. 19 b   , one side of the protrusion area  62  is adjoined with the #1 body  61   a  and the other side of the protrusion area  62  is adjoined with the #2 body  61   b.    
     In particular, the protrusion area  62  comprises: #1 slope  62   a  from #1 predetermined position of the #1 body  61   a  continued to #1 direction of the #1 body  61   a;  #2 slope  62   b  from #2 predetermined position of the #2 body  61   b  continued to #2 direction of the #2 body  61   b;  and the connection point  62   c  at which the #1 slope  62   a  and the #2 slope  62   b  meets. 
     Where the connection point  62   c  is displaced from #1 predetermined position of the #1 body  61   a  and #2 predetermined position of the #2 body  61   b,  allowing the protrusion area to be projected from the #1 belt member unit  60   a  and the #1 belt member unit  60   b.  Thus the space formed by such displacement can accommodate a cable. 
     With reference to  FIG. 19 b   , it is illustrated that #1 predetermined position of the #1 body  61   a  is the top surface of the #1 body  61   a,  and #2 predetermined position of the #2 body  61   b  is the top surface of the #2 body  61   b,  therefore, #1 direction to which the #1 slope  62   a  is extended conforms the top surface direction of the #1 slope  62   a,  and #2 direction to which the #2 slope  6   ba  is extended conforms the top surface direction of the #2 slope  62   b.    
     However, in opposite to  FIG. 19 b   , #1 predetermined position of the #1 body  61   a  can be the bottom surface of the #1 body  61   a,  and #2 predetermined position of the #2 body  61   b  can be the bottom surface of the #2 body  61   b,  therefore, #1 direction to which the #1 slope  62   a  is extended conforms the bottom surface direction of the #1 slope  62   a,  and #2 direction to which the #2 slope  6   ba  is extended conforms the bottom surface direction of the #2 slope  62   b.  However, the present invention does not limit the meaning of the top surface and the bottom surface. 
     With reference to  FIG. 19 b   , belt member sub-unit  60  of the present invention comprises the space  63  between #1 belt member unit  60   a  and the #2 belt member unit  60   b.    
     Details of such configuration have been addressed above, thus no further explanation will be provided. 
     Despite not being illustrated in drawings, considering the belt member sub-unit as a base, the belt member sub-unit can be horizontally with multiple belt member sub-units or belt member units to configure layer #1 belt member  FIG. 20 a   ,  7000 - 1 , and can also configure layer #2 belt member  FIG. 20 a   ,  70002  in an identical manner with the layer #1 belt member  FIG. 20 a   ,  7000 - 1 . 
     For a belt member in the configuration, the belt member can be defined as below, in a similar manner the belt member sub-unit is defined above. 
     Layer #1 belt member  7000 - 1  is defined as below, whilst layer #2 belt member  7000 - 2  is defined in the same manner with layer #1 belt member. 
     With reference to  FIG. 20 a    and  FIG. 20 b   , and as described above, in the present invention, layer #1 belt member  7000 - 1  and layer #2 belt member  7000 - 2  may be stacked together to conform a stacked belt member  7000 . 
     Where, the layer #1 belt member  7000 - 1  comprises #1 belt member sub-unit  60 , whilst the #1 belt member sub-unit  60  comprises: #1-1 belt member unit  60   a;  #1-2 belt member unit  60   b  immediately adjacent to the #1-1 belt member unit  60   a;  and #1-3 belt member unit no numeral immediately adjacent to the #1-2 belt member unit  60   b.    
     Where, the #1-1 belt member unit  60   a  comprises a tubular #1-1 body  61   a;  the #1-2 belt member unit  60   b  comprises a tubular #1-2 body  61   b;  and the #1-3 belt member unit no numeral comprises a tubular #1-3 body no numeral. 
     Hence, the #1-1 body  61   a,  the #1-2 body  61   b  and #1-3 body no numeral can be defined as layer #1 body. 
     Further, the layer #1 belt member  7000 - 1  comprises: #1 protrusion area  62  which one side is adjoined with the #1-1 body  61 -a and the other side is adjoined with the #1-2 body  61   b ; and #2 protrusion area no numeral which one side is adjoined with the #1-2 body  61   b  and the other side is adjoined with the #1-3 body no numeral. 
     Hence, the #1 protrusion area  62  and the #2 protrusion area no numeral can be defined as layer #2 body. 
     According to this definition, the layer #1 belt member  7000 - 1  of the present invention can be defined to comprise: layer #1 body comprising tubular #1 body  61   a,  tubular #2 body  61   b  immediately adjacent to the #1 body  61   a,  and tubular #3 body no numeral immediately adjacent to the #2 body  61   b;  and layer #2 body comprising tubular #1 protrusion area  62  located at #1 area of the #1 body and between the #1 body  61   a  and the #2 body  61   b,  and tubular #2 protrusion area no numeral located at #2 area of the #1 body and between the #2 body  61   b  and the #3 body no numeral. 
     Further, the #1 protrusion area  62  can be defined to comprise: #1-1 slope  62   a  from #1 predetermined position of #1 body continued to #1 direction of the #1 body; #1-2 slope  62   b  from #2 predetermined position of #2 body continued to #2 direction of the #2 body; and #1 connection point  62   c  at which the #1-1 slope and #1-2 slope meet, while the #2 protrusion area no numeral can be defined to comprise: #2-1 no numeral slope from #3 predetermined position of #2 body continued to #3 direction of the #2 body; #2-2 no numeral slope from #4 predetermined position of #3 body continued to #4 direction of the #3 body; #2 no numeral connection point  62   c  at which the #1-1 slope and #1-2 slope meet. 
     Hence, as described above, the #1 protrusion area  62  and the #2 protrusion area no numeral can each accommodate a cable, where by inserting a cable to the protrusion area, the protrusion area can perform the additional role to accommodate the cable, the cable supports the protrusion area allowing the protrusion area to maintain its posture even when bent, thus, the protrusion area can perform its role to prevent the layer #2 belt member and the layer #1 belt member from falling off from each other. 
     Where, the stacking relations of layer #1 belt member  7000 - 1  and layer #2 belt member  7000 - 2  has been described above, thus detail explanation is not provided, whilst, layer #2 belt member  7000 - 2  can be defined in the same manner with layer #1 belt member  7000 - 1 , thus definition of layer #2 belt member is not provided.
