Fig. 1 and 2 schematically show a handle assembly 1 according to the invention, wherein the handle assembly 1 comprises a handle 2 and a handle quick-release assembly connected to the handle 2. This quick assembly disassembly subassembly of handle simple structure easily processes, and can effectively improve the installation of handle and demolish efficiency.

As shown in fig. 2, the handle quick-release assembly comprises a tube 3 and a nut 4, wherein the tube 4 is connected to the handle 2, and the nut 4 can be sleeved on the tube 3 and can be in threaded engagement with the tube 3. In the illustrated embodiment, the tube 3 is formed at its outer periphery with a plurality of differently configured sections, including a first outer peripheral section 31 and a second outer peripheral section 32, and the first outer peripheral section 31 and the second outer peripheral section 32 are aligned and adjoining in the circumferential direction of the tube 3. The first peripheral section 31 may be configured as a smooth section without surface texture and the second peripheral section 32 is configured with a thread (thread) such that the second peripheral section 32 is convex with respect to the first peripheral section 31 and the first peripheral section 31 is concave with respect to the second peripheral section 32 and forms an arc-shaped groove extending along the outer periphery of the pipe member 3.

It should be noted that the phrase "without surface texture" as used herein means that the first peripheral section does not form a thread (thread) structure with significant unevenness on the entire surface like the second peripheral section, and the surface of the first peripheral section is substantially on a circumferential surface of the same radius as the second peripheral section as a whole, but it is not excluded that the surface of the first peripheral section is printed with, for example, an indicator (such as an arrow for guiding the mounting direction, etc.) or a trademark logo, etc., or a part of the first peripheral section is engraved with such an indicator or a trademark logo, etc., and the printed indicator or trademark logo occupies a small area in the first peripheral section, and hardly affects the smooth configuration of the first peripheral section in terms of visual and functional aspects.

In one embodiment, the outer periphery of the tube member 3 is formed with one first outer peripheral section 31 and one second outer peripheral section 32, and each first outer peripheral section 31 extends 180 ° along the outer periphery of the tube member 3, and each second outer peripheral section 32 extends 180 ° along the outer periphery of the tube member 3. In another embodiment, the outer periphery of the tube member 3 is formed with two first outer peripheral sections 31 and two second outer peripheral sections 32, each first outer peripheral section 31 extending 90 ° along the outer periphery of the tube member 3, and each second outer peripheral section 32 extending 90 ° along the outer periphery of the tube member 3, and each first outer peripheral section 31/second outer peripheral section 32 being located between two adjacent second outer peripheral sections 32/first outer peripheral sections 31. In other embodiments, the degree of extension of the first and second outer peripheral sections 31, 32 along the outer periphery of the tube 3 may be varied as desired, at least one first and at least one second outer peripheral section being present at the outer periphery of the tube 3 and abutting each other.

The nut 4 is adapted to be sleeved to the tube 3 and threadedly engaged with the tube 3. As shown in fig. 2, the nut 4 is formed at its inner periphery with a plurality of sections of different configurations, including a first inner wall section 41 and a second inner wall section 42, and the first inner wall section 41 and the second inner wall section 42 are arranged and adjacent in the circumferential direction of the nut 4. The first inner wall section 41 is configured as a smooth section without surface texture, while the second inner wall section 42 is configured with a thread (thread) which can be brought into threaded engagement with the thread (thread) of the second outer peripheral section 32 of the tube 3. The first inner wall section 41 is concave relative to the second inner wall section 42 and forms an arc-shaped groove extending along the inner circumference of the nut 4, while the second inner wall section 42 is convex relative to the first inner wall section 41.

It should be noted that the term "without surface texture" as used herein means that the first inner wall section does not have a thread (thread) structure with a distinct concave-convex shape formed on the entire surface as in the second inner wall section, but it is not excluded that the surface of the first inner wall section is printed with, for example, an indication symbol (such as an arrow indicating the installation direction, etc.) or a trademark logo, etc., or that the first inner wall section is partially engraved with such an indication symbol or a trademark logo, etc., and the engraved indication symbol or trademark logo occupies a small area of the first outer peripheral section, and hardly affects the smooth configuration of the first inner wall section in terms of visual and functional aspects.

The number of the first inner wall section 41 and the second inner wall section 42 of the nut 4 and the respective degree of extension along the inner circumference of the nut are adapted to the number and degree of extension of the first outer circumferential section 31 and the second outer circumferential section 32 of the tube 3. For example, in an embodiment in which the tube 3 has one first outer circumferential section 31 and one second outer circumferential section 32, each extending 180 °, one first inner wall section 41 and one second inner wall section 42 of the nut 4 extend 180 °. In the embodiment in which the tube 3 has two first outer circumferential sections 31 and two second outer circumferential sections 32 each extending 90 °, the two inner wall sections 41 of the nut 4 each extend 90 ° and the two second inner wall sections 42 each extend 90 °. No matter how the first and second outer peripheral sections of the pipe 3 and the first and second inner wall sections of the nut 4 are arranged, it is sufficient if the first outer peripheral section can accommodate the screw thread (thread) of the second raised inner wall section while the first inner wall section can accommodate the screw thread (thread) of the second raised outer peripheral section.

At the inner periphery of the nut 4, a radial protrusion 46 (shown in fig. 5) is formed at the intersection of the first inner wall section 41 and the second inner wall section 42, and this radial protrusion 46 serves as a stopper defining the existing position of the thread (thread) of the second inner wall section 42, facilitating quick screwing or quick unscrewing of the nut 4 to or from the pipe 3. In one embodiment, the radial projection 46 is constituted by a portion of the pin 45 screwed on the nut 4 projecting beyond the inner wall surface of the nut 4. In another embodiment, the radial projection 46 is constituted by a projection integrally formed on the inner wall surface of the nut 4.

In an embodiment, not shown, a radial protrusion may be formed at the intersection of the first outer peripheral section 31 and the second outer peripheral section 32 of the pipe member 3 as a stopper defining the existing position of the thread (thread) of the second outer peripheral section 32. In one embodiment, the radial projections are constituted by portions of the pins screwed to the pipe 3 that protrude beyond the outer wall surface of the pipe 3. In another embodiment, the radial projections are constituted by lugs integrally formed on the outer wall surface of the tube 3.

The nut 4 is also formed, on the periphery, with a pair of radially projecting lugs 43, the pair of lugs 43 being symmetrical with respect to the centre of the nut 4, on each lug 43 being threaded a movable fastener 44, for example a fastening screw.

Although the tube 3 according to the invention is particularly suitable for use in combination with the above-described nut having a first and a second inner wall section for quick assembly and disassembly of the handle, it will be appreciated by the skilled person that such a tube 3 may also be used in combination with a conventional nut 4' having a full internal thread for conventional handle mounting, as shown in fig. 3.

The process of installing the above handle assembly 1 will be described in detail with reference to fig. 4 to 9.

As shown in fig. 4, the pipe 3 connected with the handle 2 is inserted into the mounting table 5, and the gasket 6 is fitted over the pipe 3 from the side of the mounting table 5 facing away from the handle 2.

The adjusted orientation of the nut 4 relative to the tube 3 from the side of the mounting table 5 facing away from the handle 2 is such that the first inner wall section 41 of the nut 4 is aligned with the second outer circumferential section 32 of the tube 3 and the second inner wall section 42 of the nut 4 is aligned with the first outer circumferential section 31 of the tube 3. The nut 4 is at the first engagement attitude at this time. As shown in fig. 5, the fastener 44 may be adjusted so that the end near the mounting table 5 does not protrude beyond the lugs 43 of the nut 4 or only slightly protrudes beyond the lugs 43.

The nut 4 with the adjusted orientation is pushed from the end of the pipe 3 remote from the mounting table 5 toward the mounting table 5 along the axial direction of the pipe 3, and the nut 4 is moved closer to the mounting table 5 until the nut 4 abuts against the washer 6, at which time the threads (threads) of the second outer peripheral section 32 of the pipe 3 are accommodated in the first inner wall section 41 of the nut 4, and the threads (threads) of the second inner wall section 42 of the nut 4 are accommodated in the first outer peripheral section 31 of the pipe 3. This manner of coupling of the nut 4 to the tube 3 can be more easily understood with reference to fig. 6.

Referring to fig. 7 and 8, next, the nut 4 is rotated to screw the second inner wall section 42 of the nut 4 to the second outer peripheral section 32 of the pipe 3 while the first inner wall section 41 of the nut 4 is aligned with the first outer peripheral section 31 of the pipe 3, so that the nut 4 is moved to the second engagement attitude. During the rotation of the nut 4, once the radial projections 46 of the nut hit the threads of the second peripheral section 32 of the tube 3, it means that the nut 4 is rotated into position with respect to the tube 3. In the process, an installer can clearly feel that the thread (thread) of the pipe fitting 3 blocks the nut 4, and the posture of the nut on the pipe fitting can be adjusted only by hand feeling without visual inspection.

Referring to fig. 9, once the nut 4 is felt in place relative to the tube 3, the fastener can then be moved, for example screwed, so as to tighten it against the washer 6, completing the installation of the nut 4 on the tube 3.

When the nut 4 is disassembled, the steps are reversed.

It should be understood that although the specification has been described in terms of various embodiments, each embodiment does not necessarily encompass a single embodiment, and such descriptions are merely for clarity purposes and should be construed by those skilled in the art as a whole, and the embodiments may be suitably combined to form other embodiments as will be apparent to those skilled in the art.

The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent alterations, modifications and combinations can be made by those skilled in the art without departing from the spirit and principles of the invention.
