Quick release connector
A quick-release connector assembly includes a tip including a plug, a depressible member proximate the plug, and a biasing element upwardly biasing the member; and a base having a receiver and an aperture, the receiver being complementary to the plug, the base further including a connector section configured to secure a tool. The tip is releasably lockable to the base by the insertion of the plug into the receiver and the extension of the member through the aperture, and when the tip is locked with the base, the base is prohibited from rotating relative to the tip.
The invention relates generally to a connector assembly for a tool and handle.
BACKGROUNDFlow through tools typically include an extension pole having a hose connected at a first pole end and a tool connected at a second pole end. Alternatively, flow through tools include a tool directly connected to a hose. Liquid is delivered through the pole and/or hose and into the tool. The tool can be any suitable tool for dispensing water including but not limited to a watering wand, a brush, and a mop. Such tools deliver the liquid to a surface so that the surface can easily be watered, rinsed, washed, painted, or the like.
In general, two methods have been used to ensure that the tool is secured to the pole. In a first example, the tool is integral with the pole, i.e., the tool and pole are manufactured as a single article. This construction is deficient in that it does not allow the user to replace the tool on the pole.
In a second example, the pole can include a threaded element or similar structure at its second end such that the tool can be removably attached to the pole. While this addresses the disadvantage noted above, the tool may rotate relative to the pole due to the forces applied to the tool during use. Further, it is difficult to properly align the tool angle relative to the pole when typical threaded engagements are used. The user must turn the tool onto the pole until a water-tight connection is achieved. However, this may not result in a proper orientation of the tool relative to the pole, especially if the tool has been overtightened several times.
BRIEF DESCRIPTION OF THE DRAWINGSExemplary aspects and features of quick release assemblies in accordance with the disclosure are described and explained in greater detail below with the aid of the drawing figures in which:
Referring now to
The quick release assembly 24 includes a tip 34 and a base 36. The tip 34 has a front section 38 and a rear section 40. The rear section 40 of the tip 34 can be inserted into the front end 32 of the pole 22 (or directly into a hose) and is thereby secured to the pole 22. In this example, the rear section 40 is T-shaped to match the T-shaped channel in the pole 22, but the pole 22 and tip 34 can use other complementary cross sections. Such a T-section configuration is beneficial however, in that it can help to prevent rotation of the pole 22 relative to the tip 34. The tip 34 may be attached to the pole 22 in several ways, including but not limited to adhesives, screws, rivets, and crimping. As will be discussed in greater detail herein, a button assembly 42 is disposed in the front section 38 of the tip 34.
The base 36 includes a receiving portion 44, an aperture 46, and a threaded plug 48. The receiving portion 44 has a profile that matches the front section 38 of the tip 34. As will be more clearly described herein, the base 36 and tip 34 can be connected to form the quick release assembly 24 by inserting the front section 38 of the tip 34 into the receiving portion 44 of the base 36 along the longitudinal axis X. The button assembly 42 extends through the aperture 46, thereby preventing separation of the tip 34 and base 36. To remove the base 36 from the tip 34, the button assembly 42 is depressed downwardly, and the tip 34 is pulled out from the base 36.
The tool 26 shown in
As described in further detail below, both the tip 34 includes an inner channel 35 and the base 36 include an inner channel 37 extending the length of the respective part. Further, the brush 26 or other tool can include a similar inner channel 39. In use of the implement 20, the liquid source directs a liquid through the inner channel 28 of the pole 22, through the channel 35 of the tip 34, through the channel 37 of the base 36, through the channel 39 of the brush 26 and onto the bristles 54. The liquid on the bristles 54 can then be used to wash, rinse, or paint a surface. The liquid can be water, paint, liquid soap, or any other liquid.

The front section 70 is a plug 78 including a top piece 80 and a bottom piece 82. The top piece 80 generally has the shape of a paralleleipiped, while the bottom piece 82 has a generally cylindrical shape. The top piece 80 includes a button assembly 84 that allows the tip 62 to be releasably locked to the base 64. The button assembly 84 includes a button 86 that is biased by a biasing element, here a spring (see
An inner channel 92 extends from the front end 72 to the rear end 68 of the tip 62. The inner channel 92 allows fluid to flow through the tip 62 from the pole (or other liquid source) to the base 64. The inner channel 92 is disposed in the bottom piece 82 of the front section 70.
The base 64 includes a rear section 94 with a rear end 96. A receiving section 98 is disposed in the rear section 94 of the base 64 and has a shape substantially similar to that of the plug 78 of the tip 62, with a rectangular section 100 and a circular section 102. The receiver 98 defines an upper boundary 104. An aperture 106 extends through the base 64 from the receiver 98. The aperture 104 is sized and shaped to receive the button 86.
The complementary shapes of the tip plug 78 and the base receiver 98 allows the plug 78 to be inserted into the receiver 98. The depressible button 86, in its normal biased position, extends to a height above that of the upper boundary 104 of the receiver 98. During insertion of the tip 62 into the base 64, a user may manually depress the button 86 while pushing the tip 62 and base 64 together along the longitudinal axis X. Alternatively, the user may simply insert the plug 78 of the tip 62 into the receiver 64, and allow the force of the upper boundary 104 against the sloped front side 88 of the button 86 to automatically depress the button 86 as the plug 78 is inserted into the receiver 98.
Upon complete insertion of the plug 78 of the tip 62 into the receiver 98 of the base 64, the depressible button 86 extends through the aperture 106 under the force of the spring. In other words, the button 86 “snaps-up” through the aperture 106. The button 86 releasably locks the tip 62 and base 64 together and thereby prevents separation of these components. To disassemble the tip 62 from the base 64, a user may simply depress the button 86 while simultaneously pulling the tip 62 and base 64 apart in opposite directions.
The depth of insertion of the plug 78 into the receiver 98 may be limited by the engagement of the rear end 96 of the base 64 with the shoulder 74 of the tip 62. Such frictional contact may also help to stabilize the connection of the tip 62 relative to the base 64. Additionally or alternatively, the depth of insertion can be limited by the depressible button 86 on the tip 62 and the aperture 106.
While the plug 78 in this example includes a top piece 80 and a bottom piece 82, the plug 78 can generally be any non-circular shape as such shapes prevent rotation of the plug 78 relative to the base 64. For example, the plug 78 can be triangular, rectangular, octagonal, or any other non-circular shape. The plug 78 could also be generally circular with certain other elements disposed thereon to prevent rotation, such as a keyway or wings. Such configurations are considered to be non-circular. In each of the above examples, the plug 78 and the receiver 98 have complementary shapes such that the plug 78 can be inserted into the receiver 98 and rotation is prevented between the plug 78 the receiver 98. Additionally, unlike conventional threaded attachment mechanisms, the tip 62 and the base 64 do not loosen when a torque is applied about the longitudinal axis to one or more of the tip and the base.

The front section 116 includes a button assembly 128 generally similar to the button assemblies previously described. The button assembly 128 includes a depressible button 130 with a front side 132 and a back side 134. However, the button 130 does not have a sloped front side like button 84. Instead, the front side 132 is generally vertical. The back side 134 is generally vertical. The button 130 has at its base a flange 136 extending outwardly. The button assembly 128 also includes a spring 138 that provides an upwardly biasing force (i.e., +y-axis) on the button 130. A collar 140 having edges 142 can be press-fit into the tip 112 to trap the button 130 in the tip 112 by engaging the flanges 136 of the button 130. Alternatively, the collar 140 may be an integral part of the tip 112 which is formed with the tip 112 in a molding process or a machining process. The button collar 140 may also be an extruded undercut in the tip 112 that prevents the button 130 from “popping out” of place.
Similar to
During insertion of the tip 112 into the base 114, the tapered surface 148 provides a contact interface with the button 130 of less than ninety-degrees. Such a lessened angle of interface allows the tapered surface 148 to automatically depress the button 130 when the user pushes the tip 112 and base 114 together along the longitudinal axis X. However, when the tip 112 is coupled to the base 114, and the button 130 is extended in the aperture 154 (see
Upon coupling the tip 112 to the base 114, the front section 116 of the tip 112 is inserted into and locked in the receiver 144 of the base 114. The annular rib 124 on the front end 118 of the tip 112 bears against the gasket 152 in the receiver 144 of the base 114 such that the inner channel 126 of the tip 112 is in fluid communication with the inner channel 150 of the base 114. Specifically, any fluid flowing through the inner channel 126 of the tip 112 will flow through the inner channel 150 of the base 114 without any of the fluid leaking into the receiver 144. Thus, it is typically desirable for the front section 116 of the tip 112 to fit snugly in the receiver 144.

Similarly,
The tip 276 includes a rear section 278 sized and shaped to be inserted into the receiver 264. The rear section 278 has a rear end 280 and an inner channel 282 extending throughout its length, and includes a plug 284 with an engagement ledge 286 and a platform 288. The platform 288 and the engagement ledge 286 each have a flat surface 290, 292. A gasket 294 is disposed on the rear end 280 surrounding the inner channel 282.
When the tip 276 is assembled to the base 252, the button 268 extends toward the longitudinal axis X, with the button 268 bearing against the platform 288 past the engagement ledge 286. Accordingly, the engagement ledge 286 bearing against the rear side of the button 268 restricts the tip 276 from moving longitudinally relative to the base 252. Further, the flat surface 290 of the engagement ledge 286 bears against a flat internal surface 296 of the receiver 264, and the flat surface 292 of the platform 288 bears against the button 268. These interactions restrict the tip 276 from rotating relative to the base 252.
To separate the tip 276 from the base 252, a user pulls up on the tab 274 away from the longitudinal axis X which raises the button 268 above the engagement ledge 286. The assembly 250 may then separate when the user pulls the base 252 and tip 276 in opposite directions of the longitudinal axis X.
The tip 308 and the base 310 are constructed similarly as in
A paint roller 312 is shown integrally connected to the base 310 in
A variety of materials may be used to manufacture the quick release tip and the base including but not limited to die cast zinc, aluminum, stainless steel, and a variety of thermoplastic resins. Thermoplastic polymers such as, for example, polyesters, nylons, polypropylenes, and mixtures thereof are specific materials that can be used to fabricate the tip and the base.
Although the foregoing text sets forth a detailed description of numerous different embodiments of a quick-tip system, the scope of coverage of this patent is not limited thereto. On the contrary, the detailed description is to be construed as exemplary only and does not describe every embodiment of a quick-tip system.
