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 the grab pressure.
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 bore 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.
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.
Point against the aforesaid defects, the present invention is to provide a technique solution as claim 1 claimed: a pliable handle 10 comprises: a handle 1, which is composed of a plastic cover 11 with stopper flanges 110 at its ends, an open-end bore 12 has annular lips 121 at its ends; said plastic cover 11 is disposed about said open end bore 12 to define a gel-containing portion between inner wall of plastic cover 110 and outer surface of open end bore 12; a gel-injection through bore 112 is formed through the proximal flange 110 of the plastic cover 11, a gel injection through bore 123 is formed through the proximal lip 121 of the open-end bore 12; said gel injection through bore 112 is aligned with said gel injection through bore 123; refer to
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 distal end of 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 10 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 downward and fits into the open end bore 12. The projection 21 of the proximal cap 2 projects upward and fits into the open end bore 12. The proximal cap 2, distal cap 3, central pole 4 and the open end bore 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 the gel-injection through bores 112 of the plastic cover 11 and the gel injection through bore 123 of the open end bore 12. Particularly as the stopper spindle 23 is passed through the gel injection through bore 112 then fits into the 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.
The description is described according to the appended drawings thereafter.

Said plastic cover 11 is a soft, extensible hollowed sleeve with proximal, distal stopper flanges 110 at its ends. The stopper flanges 110 extended laterally inward to the center of the plastic cover 11 and spread over the annular lips 121 which is outstretched laterally from the ends of the open-end bore 12. A gel-containing portion is defined between the inner wall of the plastic cover 11 and the outer surface of the open-end bore 12. A predetermined injection through bore 123 formed through the proximal annular lip 121 is aligned with the predetermined 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
Central openings 111 are formed through the center 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 the ends of the open-end bore 12. An open-end bore 12 is made of tough hardening plastic. A central bore 120 is in communication with the proximal and the distal hollow troughs 122 at both ends of the open-end bore 12. Diameter of the hollow troughs 122 is larger than the diameter of the central bore 120 and the outer diameter of the central pole 4. The aperture of the central bore 120 is shaped to conform to the circumference of the central pole 4, or the contour and size of the aperture is identical to the cross section of the central pole 4. The central pole 4 is passed through the open-end bore 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 a diameter of apertures almost the same as the outer diameter of the central pole 4, or the contour and size of said apertures are identical to the profile 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

On one hand, as the manufacturer first made use of a needle-like injector of a syringe-like barrel (not shown) passed through the injection through bore 112 of the plastic cover 11 and injection through bore 123 of the open-end bore 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 the injection through bore 112 then fits into the 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 the outer surface of the distal hollow trough 122 of the open-end bore 12, the diameter of the groove 125 is larger than the 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 bore 12. The projections 21,31 have slits along its circumference to separate the projections 21,31 as pieces of projected plate. Thus the projections 21, 31 fits into the open end bore 12 easily but being hard to draw out of the open-end bore 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 arrayed in an axial line aligned with the central through bore 120 of the open-end bore 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 bore 12 to the central bore 32 of the distal cap 3 by means of screwing or riveting.
