Assemblies and methods for mechanically connecting and detaching separate components are generally described. In particular, assemblies and methods are described for use with an inflatable lounge.
Different assemblies and methods for mechanically connecting separate components including those of an inflatable lounge are known. However, these assemblies are often overly-complex, or if they are easily attachable they tend to be difficult to detach or prone to unwanted detachment.
Accordingly, there is a need for alternative assemblies.
Assemblies and methods for mechanically connecting and detaching separate components are generally described.
According to one more embodiments, a rotatable connector assembly is provided. The rotatable connector assembly may comprise a first connector member and a second connector member. The first connector member may comprise a cylindrical body having one or more protrusions extending radially therefrom. The second connector member may comprise a cylindrical body having a perimetral rim at an upper edge of the cylindrical body. The perimetral rim may have one or more slots therein for corresponding receipt of each of the one or more protrusions. The one or more protrusions in the first connector member may be configured to fit beneath the perimetral rim of the second connector member when the one or more protrusions are inserted fully into the one or more slots of the second connector member, so that the first connector member may be rotated relative to the second connector member.
According to one or more embodiments an inflatable lounge is provided. The inflatable lounge may comprise an inflatable body; an inflatable cushion; and a rotatable connector assembly, such as the one described above, having a first connector member attached to one of the inflatable body and the inflatable cushion, and a second connector member attached to the other of the inflatable body and the inflatable cushion.
Other advantages and novel features of the present invention will become apparent from the following detailed description of various non-limiting embodiments of the invention when considered in conjunction with the accompanying figures. In cases where the present specification and a document incorporated by reference include conflicting and/or inconsistent disclosure, the present specification shall control.
Non-limiting embodiments of the present invention will be described by way of example with reference to the accompanying figures, which are schematic and are not intended to be drawn to scale. In the figures, each identical or nearly identical component illustrated is typically represented by a single numeral. For purposes of clarity, not every component is labeled in every figure, nor is every component of each embodiment of the invention shown where illustration is not necessary to allow those of ordinary skill in the art to understand the invention. In the figures:
Assemblies and methods for mechanically connecting separate components are generally described.
According to one or more embodiments, a rotatable connector assembly is disclosed. The rotatable connector assembly may be a two-part assembly. The rotatable connector assembly may comprise a first connector member and a second connector member. The first connector member may comprise the male part of the two-part assembly. The second connector member may comprise the female part of the two part assembly.
The first connector member may comprise a cylindrical body having a one or more protrusions (e.g., teeth) extending radially therefrom. The protrusions may extend radially outwardly from the cylindrical body, for example as in the embodiment shown in
The second connector member may comprise a cylindrical body. The cylindrical body may have a perimetral rim (a rim surrounding the perimeter) at its upper edge. The perimetral rim may have one or more slots therein for corresponding receipt of each of the one or more protrusions.
According to one or more embodiments, when the first, or male, connector member is mated with the second, or female, connector member, the two members may be rotated relative to each other. Once the protrusions on the first connector part are rotated away from the slots on the second connector member, a perimetral rim extending beyond the perimeter of the first connector member cooperates with the perimetral rim on the upper edge of the second connector member to keep the two members in close association with each other while the two members may be rotated relative to each other. In some embodiments, the two members are rotatable through a full 360 degree range of motion. Alternatively, in some embodiments the two members may be rotatable through a limited range of motion of less than 360 degrees, for example, 90 degrees, to aid in positioning articles attached to the two members into a desired orientation.
The two connector members may be detached from each other by rotation of the parts until the protrusions in the first connector member are re-aligned with the slots in the second connector member, so that the two connector members may then be pulled apart.
One application of the instant invention involves the rotatable attachment of a cushion to an inflatable lounge, the invention facilitating the ready attachment and detachment of the cushion from the lounge as desired while assuring that the two parts of the connector remain attached under load and shear forces.
In
The first connector member 10 comprises a cylindrical body 12 having protrusions 14 extending radially therefrom. Two such protrusions 14 may be seen in
The embodiment shown in
The second, or female, connector member 20 of the rotatable connector assembly 1 comprises a cylindrical body 22 having a perimetral rim 24 at an upper edge 23 of the cylindrical body 22. Slots 26 formed in the perimetral rim 24 are adapted for receipt of the protrusions 14 of the first connector member 10. The perimetral rim 24 may extend inwardly as shown in
According to certain embodiments, for example, the embodiment shown in
In some embodiments, the attached pair of connector members may be detached only by aligning the protrusion(s) and slot(s) and then pulling the two members apart. In some embodiments, the connector assembly may be configured to limit or reduce the potential for unwanted or accidental disassembly. For example, the first connector member and the second connector member may be detachable at only a single, unique orientation between the first member and the second member. In some embodiments, the plurality of protrusions are not all equally spaced apart around the cylindrical body of the first connector member, such that the plurality of protrusions align with the slots at a single orientation between the first connector member and the second connector member. By limiting the necessary alignment for detachment to a single orientation, the chances for accidental disassembly are significantly reduced.
The connector parts may be machined or molded from appropriate materials, and are preferably made of Polyvinyl Chloride (PVC). The assembly may have any suitable dimensions, for example the connected assembly may have a longest cross-sectional dimension (e.g., diameter). The connector parts may be attached to articles by any suitable known or later-discovered techniques. For example, the connector parts may be heat welded to the articles to which they are attached, for example, the plastic lounge and cushion described below in relation to
According to one or more embodiments, the connector assembly, and systems or articles that incorporate the connector assembly, may be operated as follows. The one or more protrusions of the first connector member may be aligned with the one or more slots of the second connector member. The one or more protrusions may then be inserted into the one or more slots. The first member and the second member may be rotated relative to each other, bringing the protrusion(s) and slot(s) out of alignment and placing the protrusion(s) underneath the perimetral rim of the second member, and thereby securing or connecting the two connector members. While in the secured or connected state, the first connected member and second member may be rotated through a range of motion, including a full 360 degree range of motion according to some embodiments. The connector assembly may be further operated to detach the two connected members of the connector assembly. The process of detaching comprises reorienting the first connector member and the second connector member to realign the one or more protrusions of the first member from the one or more slots of the second member and withdrawing the first member from the second member. Methods of operating the connector assembly and systems or articles that incorporate the connector assembly, may incorporate any of the embodiments of the connector assembly.
The cushion 50 may then be rotated about the two connector assemblies 1 to provide adjustable back support for the user of the inflatable lounge 40. In some embodiments, the plate 16 of the first connector member 10 may be affixed to the cushion 50, and the rim 28 of second connector member 20 may be affixed to the inflatable bladder so that when the two connector members 10 and 20 are mated, the cushion 50 may rotate freely without separation of the connector members 10 and 20 under load or shear forces, and the cushion 50 may be detached from the body 41 when desired.
While several embodiments of the present invention have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the functions and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the present invention. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the teachings of the present invention is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific embodiments of the invention described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, the invention may be practiced otherwise than as specifically described and claimed. The present invention is directed to each individual feature, system, article, material, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, and/or methods, if such features, systems, articles, materials, and/or methods are not mutually inconsistent, is included within the scope of the present invention.
The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”
The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified unless clearly indicated to the contrary. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A without B (optionally including elements other than B); in another embodiment, to B without A (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.
As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.
This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Patent Application Ser. No. 62/236,221, filed Oct. 2, 2015 and entitled “ROTATABLE DETACHABLE CONNECTOR ASSEMBLY,” which is incorporated herein by reference in its entirety for all purposes.
