A variety of automotive lift systems have been made and used over the years in a variety of contexts. Some types of automotive lifts are installed in-ground, while other types are installed above-ground. In some in-ground lifts, one or more posts are selectively retractable/extendable relative to the ground to raise/lower a vehicle relative to the ground. For instance, a single post may be positioned under the center of the vehicle. Alternatively, one post may be positioned at one side of the vehicle while another post is positioned at the opposite side of the vehicle. Such one or more posts may include superstructures that are capable of engaging the vehicle. Such superstructures may be mounted or otherwise coupled near the tops of the posts, such that the superstructure is raised/lowered relative to the ground as the one or more posts are retracted/extended relative to the ground. Such superstructures may include a yoke with one or more arms movably mounted thereto. For instance, a yoke may have a pair of arms that are movable relative to the yoke to selectively position the arms relative to the yoke. Each arm may have a member that is configured to engage the vehicle.

While a variety of automotive lift systems have been made and used, it is believed that no one prior to the inventors has made or used an invention as described herein.
While the specification concludes with claims which particularly point out and distinctly claim the invention, it is believed the present invention will be better understood from the following description of certain examples taken in conjunction with the accompanying drawings, in which like reference numerals identify the same elements and in which:
The drawings are not intended to be limiting in any way, and it is contemplated that various embodiments of the invention may be carried out in a variety of other ways, including those not necessarily depicted in the drawings. The accompanying drawings incorporated in and forming a part of the specification illustrate several aspects of the present invention, and together with the description serve to explain the principles of the invention; it being understood, however, that this invention is not limited to the precise arrangements shown.
The following description of certain examples of the invention should not be used to limit the scope of the present invention. Other examples, features, aspects, embodiments, and advantages of the invention will become apparent to those skilled in the art from the following description, which is by way of illustration, one of the best modes contemplated for carrying out the invention. As will be realized, the invention is capable of other different and obvious aspects, all without departing from the invention. Accordingly, the drawings and descriptions should be regarded as illustrative in nature and not restrictive.
I. Overview of Exemplary Lift
As will be described in greater detail below, arm assemblies (130) are configured to selectively attach to a respective vehicle engagement pad (40) via an adjustable adapter (160) (see
With arm assemblies (130) and pads (40) at appropriate positions, posts (16) may be extended relative to the ground. With vehicle engagement pads (40) being engaged with the vehicle at the selected lift points, and with arm assemblies (130) being engaged with pads (40) via adjustable adapter (160) (see
II. Exemplary Arm Assembly
First segment (132) of the present example includes a mounting portion (136). Mounting portion (136) provides a coupling with superstructure (20). Mounting portion (136) includes a pair of aligned openings (138), which are configured to receive pin (32) to provide pivoting coupling of a respective arm assembly (130) with superstructure (20).
Second segment (134) telescopically extends from first segment (132) such that the effective length of arm assembly (130) may be selectively varied. In particular, first segment (132) defines a hollow interior (137) that is configured to receive second segment (134) such that second segment (134) may extend and retract relative to first segment (132) between an extended position (as shown in
Second segment (134) defines a hollow interior (139) in communication with open distal end (135). As will be described in greater detail below, hollow interior (139) is dimensioned to slidably receive adjustable adapter (160).
Second segment (134) of arm assembly (130) further defines a slot (140). First segment (132) also defines a slot (142) that extends proximally from open distal end (131). Slot (142) is substantially aligned with slot (140). In particular, slots (140, 142) are suitably aligned such that when second segment (134) is adjusted toward the retracted position (as shown in
Arm assembly (130) may further be configured such that the longitudinal position of second segment (134) relative to first segment (132) may be selectively locked once second segment (134) has been translated relative to first segment (132) to a desired longitudinal position. Various suitable ways in which such selective locking may be provided will be apparent to those of ordinary skill in the art in view of the teachings herein. In some versions, a locking mechanism or feature is omitted. For instance, in some versions, friction may substantially maintain an adjusted longitudinal positioning of second segment (134) relative to first segment (132). In other words, the mass and/or other properties of segments (132, 134) may permit a user to slide second segment (134) relative to first segment (132) to achieve an adjusted positioning; allow the user to then release second segment (134); and keep second segment (134) substantially in the adjusted position until the user again manipulates second segment (134) for further adjustment.
III. Exemplary Adjustable Adapter Configured to Couple Vehicle Pad and Arm Assembly at Multiple Profile Heights
As mentioned above, once a vehicle is initially driven over lift (10), arm assemblies (130) and vehicle engagement pads (40) may be pivoted about pins (32) until positioned under the vehicle. As also mentioned above, once arm assemblies (130) and vehicle engagement pads (40) are suitably under a vehicle, the length of arm assemblies (130) and the longitudinal position of engagement pad (40) relative to arm assemblies (130) may be adjusted in accordance with the description herein in order to suitably align vehicle engagement pads (40) with lift point positions of the vehicle.
However, in some instances, arm assemblies (130) and respective vehicle engagement pads (40) may not be able to suitably access the vehicle lift point positions. For example, while coupled with arm assembly (130), the vertical height of vehicle engagement pad (40) may extend above the maximum vertical height available for arm assembly (130) and vehicle engagement pad (40) to access the underside of a vehicle already resting on the ground. In such instances, if an operator attempted to rotate arm assembly (130) and pad (40) under the vehicle to access vehicle lift points, pad (40) may undesirably collide with the body of the vehicle.
Previously, a “low-profile” extension plate would be welded to the distal end of an arm assembly (130) such that the extension plate extended distally past open distal end (135). A “low-profile” extension plate would be able to couple with and support a vehicle engagement pad (40) at a lower vertical height compared to inserting pad (40) through slot (140) of second segment (134). Therefore, while a “low-profile” extension plate may provide access to a vehicle having a lower vertical profile, the extension plate was not adjustable relative to second segment (134).
Since this “low-profile” extension plate would permanently extend distally from open distal end (135) of second segment (142), the extension plate may act as an obstruction when either (A) second segment (134) needs to be closer to the fully retracted position (as shown in
Therefore, it may be desirable to provide an arm adapter that allows an operator to couple vehicle engagement pad (40) via slot (140) or couple with a “low-profile” section that is distal relative to open distal end (135) of second segment (134), while also providing an adjustable capability such that the “low-profile” section may be entirely restricted within second segment (134) if needed.
As will be described in greater detail below, adjustable adapter (160) is configured to translate relative to second segment (134) of arm assembly (130) such that the portion of adjustable adapter (160) forming the low-profile section may be entirely housed within second segment (134) if needed, while the portion of adjustable adapter (160) forming the low-profile section may also extend distally from open distal end (135) of second segment (134) if needed.
As best shown in
Vehicle pad receptacle (162) includes a sheath (164) and a collar (166) having a pair of flats (168). Vehicle pad receptacle (162) defines a hollow opening (165) extending from collar (166) through sheath (164). As best shown in
First body (172) and second body (174) are suitably coupled with each other. First body (172) and second body (174) are dimensioned to slidably fit within hollow interior (139) of second segment (134) such that platforms (180, 182) face upward toward slot (140). In particular, first body (172) and second body (174) are configured to be inserted into second segment (134) at open distal end (135). First body (172) and second body (174) may be inserted into open distal end (135) in the orientation shown in
First body (172) has a first thickness, while second body (174) has a second thickness. As best shown in
First body (172) and second body (174) each define a portion of a first profile through hole (176). First body (172) and second body (174) are attached to each other such that respective portions of first profile through hole (176) are suitably aligned. When first body (172) and second body (174) are slidably received within second segment (134), through hole (176) is aligned with slot (140) such that sheath (164) of receptacle (162) may be inserted through slot (140) and into first profile through hole (176). In such instances, as shown in
A portion of first body (172) also extends away from second body (174) while defining a low-profile through hole (178). As best shown in
Each platform (180, 182) is configured to support the underside of collar (166) when receptacle (162) is suitably inserted through the respective through hole (176, 178). First body (172) and second body (174) may be attached to each other through any suitable means as would be apparent to one skilled in the art in view of the teachings herein. For example, first body (172) and second body (174) may be welded together. In some instances, first body (172) and second body (174) may be integral pieces such that first profile collar platform (180) and second profile collar platform (182) are formed from a single piece of material (either through traditional manufacturing means, or through an additive manufacturing process such as 3D printing).
Additionally, second body (174) also defines a threaded opening (192) dimensioned to suitably couple with containment screw (190). Containment screw (190) may be inserted through slot (140) to selectively attach to second body (174) while adapter (160) is slidably contained within hollow interior (139) of second segment (134) to thereby prevent adapter (160) from accidentally sliding out of second segment (134). When suitably coupled, containment screw (190) extends above first profile collar platform (180) within slot (140) such that adapter (160) is restricted from actuating too far distal or proximal within second segment via contact between slot (140) and containment screw (190). Additionally, containment screw (190) may also be removed from threaded opening (192) to allow adapter (160) to be selectively removed from hollow interior (139) of second segment (134). While in the current example containment screw (190) coupled with second body (174) in a threaded manner, containment screw (190) may couple with second body (174) through any suitable means as would be apparent to one skilled in the art in view of the teachings herein. For example, containment screw (190) may be a pin easily dropped into a pin opening defined by second body (174).
When an operator desires to couple a vehicle engagement pad (40) with adapter (160) at a first profile height, the operator may insert receptacle (162) into first through hole (176) via slot (140) while first body (172) and second body (174) are slidably coupled with second segment (134), as shown in
If the operator wishes to actuate pad (40) at the first profile height distally within slot (140) to such a degree that a portion of first body (172) extends distally past open distal end (135) (as shown in
When an operator desires to couple a vehicle engagement pad (40) with adapter (16) as a low-profile height, the operator may extend adapter to the position shown in
As mentioned above, and as highlighted in
It should be understood that the operator may couple vehicle engagement pad (40) with adapter (160) at the first profile height while the portion of first body (172) including low-profile collar platform (182) is confined within the second segment (134). Therefore, adapter (160) may maintain the operability to couple with pad (40) in a low-profile configuration, while also maintaining the ability to couple with pad (40) in the first configuration without having any additional obstructions.
Having shown and described various embodiments of the present invention, further adaptations of the methods and systems described herein may be accomplished by appropriate modifications by one of ordinary skill in the art without departing from the scope of the present invention. Several of such potential modifications have been mentioned, and others will be apparent to those skilled in the art. For instance, the examples, embodiments, geometrics, materials, dimensions, ratios, steps, and the like discussed above are illustrative and are not required. Accordingly, the scope of the present invention should be considered in terms of any claims that may be presented and is understood not to be limited to the details of structure and operation shown and described in the specification and drawings.
