Description:
FIELD OF THE INVENTION 
   The present invention is related to a pliable handle, particularly to a soft pliable handle maintained temporary transformation shape and delayed to restore original configuration after releasing a grab pressure. 
   STATE OF THE PRIOR ART 
   A memory effect pliable handle is disclosed by pending applications in USPTO such as numbered US20040205938A1, which was applied on Oct. 23, 2003, is a continuation in part application of the prior pending application numbered US20040205937A1 applied on Apr. 17, 2003. Both cases have been published on Oct. 21, 2004. The US20040205937A1 teaches a core member 150, an outer sheath 120 is disposed about core member 120, a gel-containing portion 115 is defined between the core member and outer sheath, an injected gel travels through a gel injection through bore 116 fills said gel-containing portion 115. And the US20040205938A1 mentions an outer sheath 120 is disposed about a core member 110 to define a gel-containing portion 815 with the annular flanges 813, 814 at its ends, an injected gel travels through the gel injection through bores 816a, 816b formed through the annular flanges. The plugs 125, 126 are used to seal the injection bores. Thus a pliable handle is fabricated. While an exterior force exerts pressure on the pliable handle, causes load movement of gel to promote a local deformation of the handle. After a grip pressure is released, the deformed pliable handle is remained for a while until movement of gel is returned to the original shape. It has so-called memory effect pliable handle. 
   BACKGROUND OF THE INVENTION 
   Refer to FIG. 7 of said US20040205937, the central pole 150 is screwed into the core member 110, the threaded core member 110 is designed to secure the proximal end cap 130 to the outer sheath 120. Or refer to FIG. 20 of said US20040205938, the central pole 150 is screwed into the proximal end cap 1930, both the distal end cap 1940 and the proximal end cap 1930 are secured to the core member 1920 simultaneously, the distal end cap 1970 is secured to the distal sealer 1940 by means of screwing, thus keeps the gel from leaking out of the gel-containing portion. Such US20040205937A1 describes, as the threaded end 151 of the central pole 150 is designed for passing through proximal end cap 130 then secures the threaded bore 117, we can see the available Max screwing limit is in a reduced type by a decreased screw-in. However, while enduring an exterior force exerts pressure, the central pole 150 is easily being lost proper contact from the screwed portion. Sealed gel-containing portion of the outer sheath 120, 1950 is easily being leaked out the movement gel due to the threaded end is likely shown a decreased screw-on. 
   The prior art US20040205937A1 teaches that a distal end cap 140 is secured to the core member 110 by means of screwing. But the FIG. 20 of the prior art US2004205938A1 indicates that the proximal sealer 1930 is secured to the distal sealer 1940 by means of numerals 1933, 1941 indicated as screw and bore for screwing. The screwing portion is easily being lost proper contact due to long-term operation. Once a distal end cap 140 or 1970 is easily to release the capped tubing pressure leads to the containing movement of gel leaking out. 
   The prior art US20040205937A1 also teaches a nozzle is passed through the gel injection through bores 816a, 816b which are formed through the core member and outer sheath. After gel injection, the plugs are used to seal the gel injection through bore. They may be fabricated in a series of repeated and trivialized procedure, to invest the equipments or the labor cost of the production line is expensive than anticipated. production line is expensive than anticipated.

   ADVANTAGES OF EMBODIMENTS OF THE INVENTION 
   The merits can be achieved by means of the design of the present invention as following. 
   Pliable handle as the claim  1  claimed, said central pole  4  is passed through the proximal cap  2  and handle  1  to secure the distal cap  3 . In other words, the central pole  4  secures the handle  1 , proximal cap  2  and distal cap  3  simultaneously, but not combined only one or two of them to form the pliable handle  10 . So the pliable handle  10  is placed over the distal end of the central pole  4  completely. That is, not only the central pole  4  secures the pliable handle  10 , but also the pliable handle could absorb the impact as the central pole  4  endured the pressure exerted by an exterior force. The present invention thus has combined central pole  4  to form a pliable handle  10  keeps it from a partial attachment that leads to breakage or stirring movements easily. 
   The distal end of said central pole  4  secures the distal cap  3  by means of screwing or riveting. The projection  31  of the distal cap  3  projects upward and fits into the open end core  12 . The projection  21  of the proximal cap  2  projects downward and fits into the open end core  12 . The proximal cap  2 , distal cap  3 , central pole  4  and the open end core  12  are combined to form a pliable handle  10  and to seal the proximal and distal bores  111  of the plastic cover  11 . They are easy to assemble or disassemble as desired. 
   The proximal board  20  of said proximal cap  2  projects downward a stopper spindle  23 , as the proximal cap  2  presses on the handle  1 , the projected spindle  23  is used to seal one gel-injection through bores  112  of the plastic cover  11  and the other gel injection through bore  123  of the open end core  12 . Particularly as the stopper spindle  23  is passed through one gel injection through bore  112  then fits into the other gel-injection through bore  123  to achieve a preferred sealing effect so as to keep the movement of gel from leaking out of the gel-containing portion.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The description is described according to the appended drawings hereinafter. 
   Refer to  FIG. 1  is illustrated an exploded perspective view of the present invention. A pliable handle  10  includes a handle  1 , a plastic cover  11  is placed over an open end core  12 . The plastic cover  11  has a proximal and a distal stopper flanges extended inward at both ends. The open-end core  12  has a proximal and a distal annular lips  121  outreached laterally at both ends. Thus a gel-containing portion is defined between an inner wall of the plastic cover  11  and an outer surface of the open-end core  12 . An injection through bore  112  formed through the proximal flange  110  of the plastic cover  11  is aligned with an injection through bore  123  formed through the proximal annular lip  121  of the open end core  12 . Refer to  FIG. 3 , is illustrated a gel  5  injected through one injection through bore  112  and the other  123  to fill the gel-containing portion. The open-end core is surrounded by the gel  5 . A tough hardening proximal cap  2  fits onto a proximal end of the handle  1 , said proximal cap  2  has a through bore  22  at a center, a proximal board  20  has an inverse barb-like projection  21  axially projected downward from the proximal board  20 , a stopper spindle  23  projected downward from said proximal board  20 , said spindle  23  is paralleled and spaced from the projection  21 , a diameter of the projection is smaller than a diameter of the proximal board  20 , said projection  21  fits into a proximal trough  122  of the open end core  12 . The stopper spindle  23  is used to seal one injection through bore  112  and the other  123  of the handle  1 . A tough hardening distal cap  3  secures a distal end of the handle  1  by screwing with a bore  32  formed at a center of the distal cap  3 . An inverse barb-like projection  31  projected upward from the distal board  30 , a diameter of the projection  31  is smaller than a diameter of the distal board  30 . Said projection  31  fits into a distal trough  122  of the open end core  12 . After assembly, a central pole  4  is passed through the proximal cap  2 , the open-end core  12  of the handle  1  then secures to the distal cap  3 . Refer to  FIG. 2 , an assembly view of the pliable handle of the present invention is shown. Refer to  FIG. 3 , a cross section view of the pliable handle is shown. 
   Said plastic cover  11  is a soft, extensible hollowed sleeve with proximal, distal stopper flanges  110  at both ends. The stopper flanges  110  extended laterally inward to a center of the plastic cover  11  and spread over the annular lips  121  which is outstretched laterally from both ends of the open-end core  12 . A gel-containing portion is defined between an inner wall of the plastic cover  11  and an outer surface of the open-end core  12 . The other injection through bore  123  formed through the proximal annular lip  121  is aligned with one injection through bore  112  formed through the proximal flange of the plastic cover  11 . A needle-like injector of a syringe-like barrel (not shown) is passed through the aligned injection bores  112 ,  123 , then propels the gel  5  (such as silicone, mixed gel or other lotion, paste) injected through to fill said gel-containing portion as the  FIG. 3  is shown. 
   Bores  111  are formed through centers of the proximal and distal stopper flanges  110  of said plastic cover  11  respectively, which are corresponding to a proximal and a distal hollow troughs  122  formed on both ends of the open-end core  12 . The open-end core  12  is made of tough hardening plastic. A central bore  120  of the open-end core  12  is in communication with the proximal and the distal hollow troughs  122  at both ends of the open-end core  12 . A diameter of the hollow troughs  122  is larger than a diameter of the central bore  120  and a diameter of the central pole  4 . An aperture of the central bore  120  is shaped to conform to a circumference of the central pole  4 , or a contour and size of the aperture is identical to the circumference of the central pole  4 . The central pole  4  is passed through the open-end core  12  to avoid from friction and stirring movements due to the aperture of the central bore  120  is a little larger than and conformed to the circumference of the central pole  4 . Said proximal and distal hollow troughs  122  are mainly adapted to fit the projections  21 ,  31 . Owing to the central through bore  22  of the proximal cap  2  and the central bore  32  of the distal cap  3  have almost the same diameter as the central pole  4  has, or the contour and size of said bores  22 ,  32  are identical to the circumference of the central pole  4 , the central pole  4  is passed through the central through bore  22  of the proximal cap  2  then fits into the central bore  32  of the distal cap  3  to avoid from stirring movements. 
   Furthermore, said central pole  4  secures the distal cap  3  by means of screwing, which can be understood from the  FIGS. 1 and 3 . A distal end of the central pole  4  first fits into the central bore  32  of the distal cap  3 , then passes a screw  33  through a lateral bore  34  of the distal board  30 , finally secures the central pole  4  to the pliable handle  10  through a lateral bore  41  of the distal end of the central pole  4 . (The lateral bore  41  can be designed as a through bore or a bore). Besides, the same central pole  4  can secure the pliable handle  10  by means of riveting. 
   Refer to  FIG. 8 , is illustrated a longitudinal bore  36  at a center of the distal end of the distal board  30 , the longitudinal bore  36  is designed for a screw  33  passed through then fits into a straight bore  42  of the distal end of the central pole  4 . It is understood as another embodiment of screwing as the straight bore  42  instead of said lateral bore  41 . 
     FIGS. 3 and 4  are illustrated the plastic cover  11  has stopper flanges  110  at both ends, inner sides of the stopper flanges  110  has axially shift protrude positioned dots  113  to fit into positioned bores  124  formed through the annular lips  121  at both ends of the open-end core  12  respectively. Thus increased the friction between the stopper flanges  110  and annular lips  121 , as the plastic cover  11  has endured the pressure exerted by an exterior force, the stopper flange  110  and annular lip  121  can be combined to form as a whole one to avoid from shift movements. One injection through bore  112  is formed through a center of the shift protrude positioned dot  113  on the proximal stopper flange  110  of the plastic cover  11 . Whereas the corresponding distal stopper flange  110  of the plastic cover  11  has a positioned dot  113  without a bore formed through. Therefore, as the plastic cover  11  secures the open-end core  12 , and the shift protrude positioned dot  113  is adapted to the positioned bore  124 , thus is aligned one injection through bore  112  with the other injection through bore  123  on the proximal end speedily. 
   On one hand, as the manufacturer first made use of a needle-like injector of a syringe-like barrel (not shown) passed through one injection through bore  112  of the plastic cover  11  and the other injection through bore  123  of the open-end core  12 , then forces the gel  5  into the gel-containing portion, finally presses the proximal cap  2  onto the proximal end of the handle  1 . The proximal board  20  of the proximal cap  2  covers the proximal flange  110  of the plastic cover  11 . On the other hand, after gel injection, a projected stopper spindle  23  beneath the proximal board  20  is passed through one injection through bore  112  then fits into the other injection through bore  123  of the open end bore  12  to seal the injection through bores  112 ,  123 . Thus keeps the gel from leaking out. 
   Furthermore, a groove  125  is formed along an outer surface of the distal hollow trough  122  of the open-end core  12 , a diameter of the groove  125  is larger than a diameter of the distal hollow trough  122 . Said inverse barb-like projections  21 ,  31  can fit into the hollow troughs  122  at the ends of the open-end core  12 . The projections  21 , 31  have slits along circumferences to separate each of the projections  21 , 31  as pieces of projected plates. Thus the projections  21 ,  31  fit into the open-end core  12  easily but being hard to draw out of the open-end core  12 . As the proximal cap  2  fits in the proximal end of the handle  1 , the stopper spindle  23  beneath the proximal board  20  can be applied to seal the aforesaid injection through bores  112 , 123 . As the distal cap  3  fits in the distal end of the handle  1 , a protrude dot  35  formed on the distal board  30  is corresponding to and aligned with the distal end of the shift protrude positioned dot  113  on the distal flange  110  of the plastic cover  11 . The central bore  32  of the distal board  30  is in an axial line aligned with the central through bore  120  of the open-end core  12  and the through bore  22  of the proximal cap  2 . Therefore, the central pole  4  first is passed through the proximal cap  2  then secures the open-end core  12  to the central bore  32  of the distal cap  3  by means of screwing or riveting. 
   Refer to  FIG. 5 , is illustrated the manufacturer applies a needle-like injector of a syringe-like barrel (not shown) to inject the gel  5  through the injection through bores  112 , 123  then fits into the gel-containing portion. After gel injection, the proximal cap  2  is used to press the proximal end of the handle  1 , the proximal board  20  of the proximal cap  2  is provided as a cover for the proximal flange  110  of the plastic cover  11 . And the projected stopper spindle  23  beneath the proximal board  20  presses close the injection through bores  112 ,  123 . But the projected spindle  23  is still not used to seal the bores  112 ,  123 . Until the injected needle-like injector is pulled out, one injection through bore  112  of the plastic cover  11  is restored to the original configuration sealing the other injection through bore  123  of the open-end core  12  by elasticity. After that, due to the sealed injection through bore  112  being pressed and sealed by the projected spindle  23 , the gel  5  is prevented from from leaking out. 
   Refer to  FIG. 7 , as the user exerts pressure on the pliable handle  10  by hand, the plastic cover  11  and the gel  5  is in a transformation shape. The plastic cover  11  keeps an ergonomic touch conformed to the fingers shape. Refer to  FIG. 8 , as the users release the comfort hand grab, the pliable handle still keeps the temporary transformation shape of the fingers contour. Until the gel  5  is flowed slowly to restore to the original configuration of the pliable handle  10 . 
   Said central pole  4  is not only suitable for an umbrella. Refer to  FIGS. 9 and 10 , are illustrated said central pole  4  is applied to a spade  6 , or a hammer  7  as an outstretched pole. Another embodiments of the pliable handle can be applied to walking stick, screwdriver, club.
