For each of the connecting members 12, by turning the screw 123 relative to the holding portions 122, the holding space 120 can be enlarged or shrunken so that the connecting member 12 may be movable along the post 11 or be secured on the post 11 for positioning the corresponding monitor 2 relative to the post 11 at a desired position.

However, the screw 123 of each of the connecting members 12 needs to be operated using a hand tool such as a screwdriver or a wrench, rendering adjustment of the connecting member 12 inconvenient. Moreover, each connecting member 12 cannot be mounted with multiple arms 13.

SUMMARY

Therefore, an object of the disclosure is to provide a quick connector that can alleviate at least one of the drawbacks of the prior art.

According to the disclosure, the quick connector is for being separably mounted to a first object, and includes a holding member, a connecting member and an operating member. The holding member extends around an axial line to define a holding space that is adapted to permit the first object to extend therethrough, and has two driven end portions. The connecting member has a first end portion that is pivoted to one of the driven end portions of the holding member at a first pivot point, and a second end portion that is opposite to the first end portion. The operating member has a pivot end portion that is pivoted to the other one of the driven end portions of the holding member at a second pivot point, and an operating end portion that is opposite to the pivot end portion and that is pivoted to the second end portion of the connecting member at a third pivot point. The quick connector is operable to switch between a released state in which the operating end portion is spaced apart from the holding member, and a holding state in which the operating end portion abuts against the holding member. The third pivot point moves from one of two opposite sides of an imaginary line that passes through the first and second pivot point to the other one of the opposite sides of the imaginary line during conversion of the quick connector from one of the released state and the holding state to the other one of the released state and the holding state.

DETAILED DESCRIPTION

Before the disclosure is described in greater detail, it should be noted that where considered appropriate, reference numerals or terminal portions of reference numerals have been repeated among the figures to indicate corresponding or analogous elements, which may optionally have similar characteristics.

Referring to FIGS. 2 to 4, the first embodiment of the quick connector according to the disclosure includes a holding member 3, a connecting member 4, an operating member 5, two cushion pads 6 and a pivot unit 7.

The holding member 3 includes two holding arms 31 that cooperatively define a holding space 30 therebetween and that extend around an axial line (X1). Each of the holding arms 31 has a connecting end portion 311, a driven end portion 312 that is opposite to the connecting end portion 311, a seat portion 313 that surrounds a central line (X2a, X2b) to define a mounting hole 310, and an inner surface 315 that faces the holding space 30 and that is formed with a plurality of recesses 314. The driven end portion 312 of each of the holding arms 31 is formed with a breach 316. The connecting end portions 311 of the holding arms 31 are pivoted to each other.

The connecting member 4 has a first end portion 41, and a second end portion 42 opposite to the first end portion 41. The first end portion 41 of the connecting member 4 is mounted to the breach 316 of one of the holding arms 31, and is pivotable relative to the driven end portion 312 of the one of the holding arms 31 about a first pivot point (A).

The operating member 5 has a pivot end portion 51, and an operating end portion 52 that is opposite to the pivot end portion 51. The pivot end portion 51 of the operating member 5 is mounted to the breach 316 of the other one of the holding arms 31, and is pivotable relative to the driven end portion 312 of the other one of the holding arms 31 about a second pivot point (B). The second end portion 42 of the connecting member 4 and the operating end portion 52 of the operating member 5 are pivotable relative to each other about a third pivot point (C) (see FIGS. 7 to 9). The operating end portion 52 has an extension 521. In some embodiment, the operating member 5 has two spaced apart lugs 511 each of which partially forms the pivot end portion 51 and partially forms the operating end portion 52. The lugs 511 permit the second end portion 42 of the connecting member 4 to extend therebetween.

Referring to FIGS. 2 and 7, the cushion pads 6 are respectively mounted to the inner surfaces 315 of the holding arms 31. Each of the cushion pads 6 has an outer surface 62 that is formed with a plurality of protrusions 61 engaging the recesses 314 of the corresponding one of the holding arms 31. It should be noted that, in some embodiment, there may be only one cushion pad 6.

The pivot unit 7 includes a first pivot member 71 that pivotally interconnects the connecting end portions 311 of the holding arms 31, a second pivot member 72 that pivotally interconnects the first end portion 41 of the connecting member 4 and the driven end portion 312 of the one of the holding arms 31 and that forms the first pivot point (A), two third pivot members 73 that pivotally interconnects the pivot end portion 51 of the operating member 5 and the driven end portion 312 of the other one of the holding arms 31 and that form the second pivot point (B), and a fourth pivot member 74 that pivotally interconnects the second end portion 42 of the connecting member 4 and the operating end portion 52 of the operating member 5 and that forms the third pivot point (C).

The quick connector according to the disclosure is operable to switch among a holding state (see FIG. 7), a released state (see FIG. 8) and a transition state (see FIG. 9). Referring to FIG. 8, when the quick connector is in the released state, the driven end portions 312 of the holding member 3 are spaced apart from each other by a released distance (D), the third pivot point (C) and a major portion of the holding member 3 are respectively located at two opposite sides of an imaginary line (L) that passes through the first and second pivot points (A, B), and the extension 521 of the operating member 5 is spaced apart from the holding member 3. Referring to FIG. 7, when the quick connector is in the holding state, the driven end portions 312 of the holding member 3 are spaced apart from each other by a holding distance (d) smaller than the released distance (D), the third pivot point (C) and the major portion of the holding member 3 are located at the same side of the imaginary line (L), and the extension 521 of the operating member 5 abuts against the holding member 3. Referring to FIG. 9, when the quick connector is in the transition state (transiently), the third pivot point (C) is located on the imaginary line (L), and the driven end portions 312 of the holding member 3 are closest to each other. In some embodiment, when the quick connector is in the holding state, the connecting member 4 and the operating member 5 extend along an arc that extends around the axial line (X1). In some embodiment, the path of movement of the third pivot point (C) is configured not to pass through a space between the first and second pivot point (A, B).

Referring to FIGS. 5 and 6, the quick connector according to the disclosure is adapted for interconnecting a first extending member 81 and two second extending members 82. The first extending member 81 may be configured as a post that extends along the axial line (X1). Each of the second extending members 82 may be configured as a support arm that supports a monitor 9 and that is mounted to a respective one of the mounting holes 310 of the holding member 3.

To mount the quick connector onto the first extending member 81, the quick connector is first switched into the released state and sleeved on the first extending member 81, then the operating member 5 is operated to switch the quick connector into the holding state through the transition state so as to position the quick connector relative to the first extending member 81.

During the conversion from the released state to the transition state, the driven end portions 312 of the holding member 3 approach each other to shrink the holding space 30, so that friction is generated between the cushion pads 6 and the first extending member 81 and that the driven end portions 312 of the holding member 3 tend to move away from each other. When the third pivot point (C) moves past the imaginary line (L) to the side at which the major portion of the holding member 3 is located, the relative movement between the driven end portions 312 of the holding member 3 away from each other drives the extension 521 of the operating member 5 to move to abut against the holding member 3, so that the driven end portions 312 of the holding member 3 cannot move further away from each other, and that the quick connector is maintained in the holding state to be positioned relative to the first extending member 81.

To move the quick connector along the first extending member 81, the operating member 5 is operated to switch the quick connector into the released state so that the holding space 30 is enlarged and the friction generated between the cushion pads 6 and the first extending member 81 is diminished to permit relative movement between the quick connector and the first extending member 81.

Referring to FIG. 10, the holding member 3 of a modification of the first embodiment has only one holding arm 31. The holding arm 31 is flexible and has the driven end portions 312. By operation of the operating member 5, the quick connector can also be switched among the released state, the transition state and the holding state, as the embodiment illustrated above, so as to be positioned relative to the first extending member 81 or to be permitted to move along the first extending member 81.

In some embodiment, the holding space 30 may be circular, elliptic, rectangular, polygonal, and so on.

Referring to FIG. 11, the second embodiment of the quick connector according to the disclosure is similar to the first embodiment, and includes the holding member 3, the connecting member 4, the operating member 5, the cushion pads 6 and the pivot unit 7.

One of the holding arms 31 of the second embodiment further has an extending portion 317 that is connected to the seat portion 313. The operation of the second embodiment is the same as that of the first embodiment.

The advantages of the quick connector of the disclosure are as follows:

1. The quick connector is switched by operation of the operating member 5. There is no need for an additional hand tool.

2. By the variation of the location of the third pivot point (C), the quick connector can be maintained in the holding state.

3. The protrusions 61 of the cushion pad 6 facilitates positioning between the cushion pad 6 and the holding arm 31, and serves to increase the thickness of the cushion pad 6.

4. The holding member 3 may include multiple mounting holes 310 for being mounted with multiple support arms.
