The present invention generally relates to the structure of a handle of hand-held devices, such as handles of walking sticks, umbrellas and fish pole.
All kinds of pliable handles based on known technology have a flexible outer sheath disposed about the core member hermetically, and deformable gel is disposed between the core member and the outer sheath. In the structure of the pliable handle shown in
For controlling the unfurling and furling in some hand-held umbrellas, there is a clasp in the central rod of an umbrella, the clasp is attached to a slip cover to which many subordinate rods of umbrella is connected. When the umbrella is furled, the clasp locked the slip cover and made umbrella furl. The clasp is connected to a button, after pressing the button the clasp is detached from the slip cover, and the umbrella is unfurled. When the umbrella is furled, the clasp locked the slip cover again. For beauty and using conveniently, a through opening is set in the side wall of the core member, containing a button. When people grip the pliable handle, they can press the button with their thumb, making the clasp is detached from the slip cover, and the umbrella is unfurled. According to the structure of above-mentioned pliable handle, a through opening which contains a button in the side wall of the core member, when people grip the pliable handle, the gel may be leaked from the gap between the through opening and a button into the space between the inside of the core member and central rod of umbrella, it may hinder the movement of the button at worst. Additionally, if a button through the outer sheath, the gel may be leaked from the gap between the outer sheath and a button and go out of the outer sheath.
Some handles of hand-held devices, such as the handles of walking stick, fish pole, for using conveniently at night and the function of caution, a through opening is set in the side wall of the core member, containing a button battery, small bulb, luminous diode and so forth and a button switch. When people grip the pliable handle, they can press the button switch with their thumb, the button battery and luminous components form a closed circuit in series, the pliable handle radiated at night by the light of electrical luminous component, so the people who is far away can get the caution, and know the position of user. If the handle having a button component has the structure the same as the above-mentioned pliable handle's, there is an above-mentioned gel-leak problem.
