DETAILED DESCRIPTION

Before turning to the figures, which illustrate certain exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting. The various concepts introduced above and discussed in greater detail below may be implemented in any number of ways, as the described concepts are not limited to any particular manner of implementation. Examples of specific implementations and applications are provided primarily for illustrative purposes.

Embodiments of the application are further described below with reference to the accompanying figures, wherein like reference numerals refer to like elements. It should be noted that, terms as used in the following description, “front”, “rear”, “left”, “right”, “up” and “down” indicate a direction in the figures, and terms “inner” and “outer” respectively indicate the direction towards or away from a geometric center of a particular part.

A faucet can include a faucet body and a faucet outlet. The faucet outlet may be coupled to a fluid conduit that is configured to slide within the faucet body. A length of the fluid conduit may at least partially protrude from a first end of the faucet body (e.g., an above sink end) and/or a second end of the faucet body (e.g., under sink end, a base end, etc.). The faucet outlet may be removably coupled to the faucet body in a first position in which a length of fluid conduit protrudes from the second end of the faucet body. The faucet outlet may be displaced from the faucet body in a second position in which a length of fluid conduit protrudes from the first end of the faucet body and spans between the faucet body and faucet outlet.

A user can draw the fluid conduit (e.g., pipe, hose, flexible tubing, water pipe, water hose, etc.) from the faucet body to adjust the length of the fluid conduit, so that the position and angle of the faucet outlet relative to the faucet body can be adjusted, which is convenient to use.

The fluid outlet and fluid conduit may be biased from the second position (e.g., the pulled-out position, the pulled-down position, the extended position, etc.) toward the first position (e.g., a home position, a compact position, a docked position, etc.) by a retractor. A retractor can include a weight suspended along a length of the fluid conduit that pulls the fluid conduit through the faucet body (e.g., as the weight falls). However, such retractors are burdensome and difficult to use. For example, the biasing force of the retractor must be overcome and sustained in order to maintain the faucet outlet in the second position. For example, a user may pull on the faucet outlet (e.g., which may lift the weight) and overcome the biasing force. However, when a user does not overcome the biasing force of the retractor (e.g., does not continue to pull on the faucet outlet), the retractor retrieves the fluid conduit through the faucet body.

When a typical water pipe drawing mechanism is in use, users need to keep drawing the water pipe to avoid retraction of the water pipe, which is inconvenient to use.

The application aims to provide a retractor assembly to overcome the shortcomings of the prior art, such as burdensome positioning and strenuous drawing. Aiming at the technical problems, the application provides the following technical solutions.

The application discloses a pipe drawing mechanism including a housing, a top cover, a rotary plate, a swing arm with a guide protrusion, an outlet pipe and an elastic drive member; a side of the rotary plate facing the swing arm is provided with an outer guide groove and an inner guide groove which are in clearance fit with the guide protrusion; a first channel and a second channel are connected between the outer guide groove and the inner guide groove at intervals, the guide protrusion can enter the inner guide groove from the outer guide groove via the first channel, and the guide protrusion can enter the outer guide groove from the inner guide groove via the second channel; the second channel has a locking groove therein for locking the guide protrusion. The pipe drawing mechanism of the application has locking function and is convenient for users to use.

An object of the application is to overcome the shortcomings of the prior art and provide a pipe drawing mechanism with locking function.

A technical solution of the application provides a pipe drawing mechanism including a housing with a holding cavity, a top cover mounted on the housing and having an inlet channel, a rotary plate pivotally mounted in the holding cavity, a swing arm pivotally mounted in the holding cavity and having a guide protrusion, an outlet pipe wound on the rotary plate and an elastic drive member mounted in the holding cavity and used to drive the rotary plate to reset; one end of the outlet pipe is connected with the inlet channel and other end of the outlet pipe passes through the holding cavity; one side of the rotary plate that facing the swing arm has an outer guide groove and an inner guide groove which are in clearance fit with the guide protrusion; a first channel and a second channel are connected between the outer guide groove and the inner guide groove at intervals, the guide protrusion is able to enter the inner guide groove from the outer guide groove via the first channel and the guide protrusion is able to enter the outer guide groove from the inner guide groove via the second channel; and the second channel has a locking groove therein for locking the guide protrusion.

In some embodiments, the locking groove is a bending groove provided in the second channel.

In some embodiments, the guide protrusion is a guide cylinder.

In some embodiments, a bottom plate of the housing has a connection column, one end of the swing arm is pivotally mounted on the connection column.

In some embodiments, a terminal end of the swing arm has a support end extending towards the bottom plate, the support end is on the bottom plate.

In some embodiments, the rotary plate includes a circular groove, the outlet pipe is wound in the circular groove.

In some embodiments, the rotary plate is fitted with an adapter connected to the inlet channel, one end of the outlet pipe is connected to the adapter.

In some embodiments, the adapter includes an adapting pipe and a pipe fitting attached to one side of the adapting pipe; the rotary plate has a central sleeve in the central part, one side of the central sleeve has a sleeve notch; and the adapting pipe is installed in the central sleeve and communicated with the inlet channel, the pipe fitting protrudes from the sleeve notch and is connected with the outlet pipe.

In some embodiments, a bottom of the top cover has an insert-pipe connected with the inlet channel, the insert-pipe is inserted in the adapting pipe.

In some embodiments, a bottom of the rotary plate has a storage groove, the elastic drive member is located in the storage groove.

Advantageously, when the outlet pipe is drawn outward, the rotary plate rotates in the positive direction and compresses the elastic driving member, and the guide protrusion enters the inner guide groove from the outer guide groove via the first channel, according to some embodiments. After the user stops drawing the outlet pipe, the user can release the outlet pipe, and under the action of the elastic drive member, the rotary plate starts to rotate in the reverse direction and drive the outlet pipe to retract a certain length. During the process, the guide protrusion will enter the locking groove of the second channel from the inner guide groove to prevent the rotary plate from rotating in the reverse direction, and the outlet pipe is locked and no longer retracted. When the user needs to retract and collect the outlet pipe, the user can draw the outlet pipe again, the guide protrusion will leave the locking groove and enter the outer guide groove. The outlet pipe will be retracted automatically after the user releases it.

Thus, the application provides an improved pipe drawing mechanism with a locking function, which is convenient for users to use.

As shown in FIGS. 1-12, a retractor assembly (e.g., retractor, reel, retriever, etc.), shown as pipe drawing mechanism 0 includes a housing 1 defining a holding cavity 10 (e.g., an internal volume, a space, etc.), a top cover 2 (e.g., cover, lid, top plate, top, etc.) mounted on the housing 1 and having an inlet channel 21 (e.g., an inlet, intake, inlet port, intake port, etc.), a rotary plate 3 (e.g., spool) pivotally mounted in the holding cavity 10, a swing arm 5 (e.g., guide arm, cam arm, cam follower arm, etc.) pivotally mounted in the holding cavity 10 and having a guide protrusion 51 (e.g., a follower), a fluid conduit (e.g., flexible tube, hose, pipe, etc.) shown as outlet pipe 6 configured to be wrapped around (e.g., spooled onto, coiled onto, etc.) the rotary plate 3, and an elastic drive member 7 (e.g., spring, torsional spring, magnet, etc.) mounted in the holding cavity 10 and configured to drive the rotary plate 3 to reset (e.g., drive the rotary plate 3 to rotate toward a reset position, supply a torque to return the rotary plate 3 to a reset position). For example, the elastic drive member 7 may bias the rotary plate 3 to rotate toward a home position where the torsional spring is in a rest state (e.g., an unloaded state, a non-deformed state, etc.).

In some embodiments, one end of the outlet pipe 6 is connected to the inlet channel 21 and the other end penetrates (e.g., is external to) the holding cavity 10.

In some embodiments, an outer guide groove 31 (e.g., outer track) and an inner guide groove 32 (e.g., inner track) in clearance fit with the guide protrusion 51 are arranged on a side of the rotary plate 3 facing the swing arm 5. The rotary plate 3 may pivot about a pivot axis DD (see, FIG. 8). For example, the rotary plate 3 may be pinned within the holding cavity 10 by, for example, a portion of the housing 1 and/or the cover 2. The outer guide groove 31 may define an outer groove path (e.g., groove track, etc.) that extends around the pivot axis DD and the inner guide groove 32 may define a inner groove path (e.g., inner groove track, etc.,) that extends around the pivot axis DD. A distance between the axis DD and the outer guide groove 31 may be greater than a distance between the inner guide groove 32. The outer guide groove 31 may be radially further from the pivot axis DD than the inner guide groove 32. In some embodiments, the outer guide groove 31 and the inner guide groove 32 have a circular path around the pivot axis DD. The radius of the path of the outer guide groove 31 may be larger than the radius of the path of the inner guide groove 32. In some embodiments, the inner guide groove 32 is proximate the pivot axis DD and the outer guide groove is distal the pivot axis DD. In some embodiments, the outer guide groove 31 is proximate the perimeter of the rotary plate 3. In some embodiments, the path of the outer guide groove 31 and the path of the inner guide groove 32 are concentric about the pivot axis DD.

In some embodiments, a first channel 33 (e.g., a first passage, a first ramp, etc.) and a second channel 34 (e.g., a second passage, a second ramp, etc.) are connected between the outer guide groove 31 and the inner guide groove 32. The guide protrusion 51 is able to enter the inner guide groove 32 from the outer guide groove 31 via the first channel 33, and the guide protrusion 51 is able to enter the outer guide groove 31 from the inner guide groove 32 via the second channel 34. For example, the guide protrusion 51 may travel along the groove path of the outer guide groove 31 and selectively be diverted into the inner guide groove 32 via the second channel 34.

In some embodiments, a locking groove 341 (e.g., elbow, bend, pocket, corner, catch, etc.) for locking the guide protrusion 51 is provided in the second channel 34. In some embodiments, the depth of the outer guide groove 31, the inner guide groove 32, the first channel 33 and the second channel 34 is similar. In some embodiments, the bottom surface of the outer guide groove 31, the inner guide groove 32, the first channel 33 and the second channel 34 is flat. For example, the cross section (e.g., groove profile) of the outer guide groove 31, the inner guide groove 32, the first channel 33, and the second channel 34 may be substantially uniform.

In some embodiments, the pipe drawing mechanism 0 includes a housing 1, a top cover 2, a rotary plate 3, a swing arm 5, an outlet pipe 6 and an elastic drive member 7.

In some embodiments, the top cover 2 is mounted on the housing 1 by screws, and a holding cavity 10 is formed between the housing 1 and the top cover 2. The housing 1 includes a circular bottom plate 11 and a circle of side plate mounted around the bottom plate 11, and a line outlet 12 is provided on the side plate. The top cover 2 has an inlet channel 21 arranged on it.

In some embodiments, the rotary plate 3 is connected between the bottom plate 11 and the top cover 2 by a pivoting shaft or a central sleeve, and the rotary plate 3 is rotatable in the holding cavity 10. The swing arm 5 is mounted on the bottom plate 11 by the pivot shaft, and the swing arm 5 is between the bottom plate 11 and a bottom side of the rotary plate 3. The top side of the swing arm 5 has a guide protrusion 51.

In some embodiments, the outlet pipe 6 is a soft pipe, and the outlet pipe 6 is wound on the rotary plate 3. One end of the outlet pipe 6 is communicated with the inlet channel 21 and communicated to the water path. The other end of the outlet pipe 6 extends through the line outlet 12 to the outside of the housing 1. The other end of the outlet pipe 6 can be connected to a sprayer, a faucet or a water-consuming device.

In some embodiments, the elastic drive member 7 is mounted between the bottom plate 11 and the rotary plate 3, and it is used to drive the rotary plate 3 to reset. When the user draws the outlet pipe 6, the rotary plate 3 rotates in the positive direction and the elastic drive member 7 is compressed. After the user releases the outlet pipe 6, the rotary plate 3 rotates in the reverse direction by the action of the elastic drive member 7, to wrap the outlet pipe 6 around the rotary plate 3, and the outlet pipe 6 is retracted and collected.

In some embodiments, a circle of outer guide groove 31 and a circle of inner guide groove 32 are arranged at the bottom surface of the rotary plate 3, and the inner guide groove 32 is located inside the outer guide groove 31. The inner guide groove 32 is arranged coaxially with the outer guide groove 31.

In some embodiments, the guide protrusion 51 is in clearance fit with the inner guide groove 32 and the outer guide groove 31. The guide protrusion 51 can slide in the inner guide groove 32 and the outer guide groove 31.

In some embodiments, there is a first channel 33 connected between the outer guide groove 31 and the inner guide groove 32, and the rotary plate 3 is driven to rotate in the positive direction when the outlet pipe 6 is drawn out, and the guide protrusion 51 can enter the inner guide groove 32 from the outer guide groove 31 via the first channel 33.

In some embodiments, there is also a second channel 34 connected between the outer guide groove 31 and the inner guide groove 32, and the second channel 34 and the first channel 33 are arranged at intervals. After the user releases the outlet pipe 6, the rotary plate 3 rotates in the reverse direction and the guide protrusion 51 can enter the outer guide groove 31 from the inner guide groove 32 via the second channel 34.

In some embodiments, the second channel 34 has a locking groove 341 therein for locking the guide protrusion 51 to prevent the rotary plate 3 from rotating in reverse direction, thus the outlet pipe 6 is locked in place. When the user needs to retract the outlet pipe 6, the user draws the outlet pipe 6 again, and the guide protrusion 51 will leave the locking groove 341 and enter the outer guide groove 31, and the outlet pipe 6 is automatically retracted and collected when the user releases his hand.

In some embodiments, in the pipe drawing mechanism 0, when the outlet pipe 6 is drawn out, the rotary plate 3 rotates in the positive direction and compresses the elastic drive member 7, and the guide protrusion 51 enters the inner guide groove 32 from the outer guide groove 31 via the first channel 33. When the user stops drawing the outlet pipe 6, the user can release the outlet pipe 6, and under the action of the elastic drive member 7, the rotary plate 3 starts to rotate in reverse direction and drive the outlet pipe 6 to retract a certain length. During the process, the guide protrusion 51 will enter the locking groove 341 of the second channel 34 from the inner guide groove 32 to prevent the rotary plate 3 from rotating in the reverse direction, then the outlet pipe 6 is locked and no longer retracted. When the user needs to retract the outlet pipe 6, the user draws the outlet pipe 6 again, the guide protrusion 51 will leave the locking groove 341 and enter the outer guide groove 31, and the outlet pipe 6 will be automatically retracted after the user releases it.

Thus, the application provides a pipe drawing mechanism 0 with a locking function, which is convenient for users to use.

As shown in FIG. 9, the locking groove 341 is a bending groove provided in the second channel 34, according to some embodiments. The bending groove has a simple structure and can be conveniently arranged in the second channel 34. The guide protrusion 51 can be locked at a bend after the guide protrusion 51 enters the bending groove. After the user draws the outlet pipe 6 here, the guide protrusion 51 can leave the bend of the bending groove and enter the outer guide groove 31.

As shown in FIG. 10, the guide protrusion 51 is a guide cylinder, which has a small contact area and low friction with the outer guide groove 31, the inner guide groove 32, the first channel 33 and the second channel 34, which facilitates the guide cylinder to slide relative to the guide groove and channel, according to some embodiments.

As shown in FIG. 2, FIG. 4 and FIG. 10, the bottom plate 11 of the housing 1 has a connection column 13, and one end of the swing arm 5 is pivotally mounted on the connection column 13 which facilitates assembly of the swing arm 5 with the bottom plate 11, according to some embodiments. For example, the swing arm 5 may include a pivot 52 configured to engage the connection column 13 and thereby pivotally couple the swing arm 5 to the bottom plate 11 of the housing 1. The top end of the connection column 13 has an end cap (e.g., shoulder, head, etc.), which serves to prevent the swing arm 5 from separating from the connection column 13.

As shown in FIG. 10, a terminal end of the swing arm 5 has a support end 53 (e.g., support tab, tab, elbow, nib, etc.) extending toward the bottom plate 11, which is in contact with the bottom plate 11 and acts as a support to keep the guide protrusion 51 able to be in the outer guide groove 31, the inner guide groove 32, the first channel 33 and the second channel 34, according to some embodiments.

As utilized herein with respect to numerical ranges, the terms “approximately,” “about,” “substantially,” and similar terms generally mean +/−10% of the disclosed values, unless specified otherwise. As utilized herein with respect to structural features (e.g., to describe shape, size, orientation, direction, relative position, etc.), the terms “approximately,” “about,” “substantially,” and similar terms are meant to cover minor variations in structure that may result from, for example, the manufacturing or assembly process and are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains. Accordingly, these terms should be interpreted as indicating that insubstantial or inconsequential modifications or alterations of the subject matter described and claimed are considered to be within the scope of the disclosure as recited in the appended claims.

It should be noted that the term “exemplary” and variations thereof, as used herein to describe various embodiments, are intended to indicate that such embodiments are possible examples, representations, or illustrations of possible embodiments (and such terms are not intended to connote that such embodiments are necessarily extraordinary or superlative examples).

The term “coupled” and variations thereof, as used herein, means the joining of two members directly or indirectly to one another. Such joining may be stationary (e.g., permanent or fixed) or moveable (e.g., removable or releasable). Such joining may be achieved with the two members coupled directly to each other, with the two members coupled to each other using a separate intervening member and any additional intermediate members coupled with one another, or with the two members coupled to each other using an intervening member that is integrally formed as a single unitary body with one of the two members. If “coupled” or variations thereof are modified by an additional term (e.g., directly coupled), the generic definition of “coupled” provided above is modified by the plain language meaning of the additional term (e.g., “directly coupled” means the joining of two members without any separate intervening member), resulting in a narrower definition than the generic definition of “coupled” provided above. Such coupling may be mechanical, electrical, or fluidic.

References herein to the positions of elements (e.g., “top,” “bottom,” “above,” “below”) are merely used to describe the orientation of various elements in the FIGURES. It should be noted that the orientation of various elements may differ according to other exemplary embodiments, and that such variations are intended to be encompassed by the present disclosure.

Although the figures and description may illustrate a specific order of method steps, the order of such steps may differ from what is depicted and described, unless specified differently above. Also, two or more steps may be performed concurrently or with partial concurrence, unless specified differently above. It is important to note that any element disclosed in one embodiment may be incorporated or utilized with any other embodiment disclosed herein.
