Abstract

A joint assembly ( 100 ) between multiple air chambers of an inflatable product (P). The joint assembly ( 100 ) may include a male component ( 102 ) coupled to a first air chamber and a female component ( 104 ) coupled to a second air chamber. When assembled, the multiple air chambers of the inflatable product may be in fluid communication with each other or with a multichannel air assembly configured to selectively inflate and/or deflate each chamber.

First claim

What is claimed is:

1. A joint assembly for an inflatable product, the inflatable product defining a first air chamber and a second air chamber, the joint assembly comprising:
a male component, the male component comprising a cap with a first protrusion and at least one first locking feature extending from the cap, the first protrusion and the cap defining a first conduit therethrough in fluid communication with the first air chamber;
a female component, the female component comprising a head with a second protrusion extending from the head, the second protrusion and the head defining a second conduit therethrough in fluid communication with the second air chamber, wherein at least a portion of the second conduit is sized and shaped to receive the first protrusion of the male component, and wherein the head includes an annular recess defined by an outer wall and an inner wall;
a locking ring, the locking ring comprising a locking base sized to rotate in the annular recess of the female component, the locking ring further comprising at least one second locking feature configured to interact with the at least one first locking feature of the male component based on rotation of the locking ring; and
a gasket coupled to the female component to capture the locking ring in the annular recess.

2. The joint assembly of claim 1 , wherein:
the at least one first locking feature of the male component comprises a lip that extends radially outward; and
the at least one second locking feature of the locking ring comprises a lip that extends radially inward toward the lip of the male component.

3. The joint assembly of claim 1 , the locking ring further comprising a grip portion extending radially outward beyond the male and female components.

4. The joint assembly of claim 1 , wherein the male component comprises at least two first locking features and the locking ring comprises at least two second locking features.

5. The joint assembly of claim 1 , wherein the gasket is T-shaped in cross section, the gasket comprising:
a first portion that extends into the annular recess between the locking ring and the inner wall of the female component;
a second portion that extends radially inward to couple with the inner wall of the female component; and
a third portion that extends radially outward to overlay the locking ring.

6. The joint assembly of claim 1 , wherein the joint assembly includes a locked configuration, in which the at least one second locking feature of the locking ring engages the at least one first locking feature of the male component.

7. The joint assembly of claim 1 , wherein the joint assembly includes an unlocked configuration, in which the at least one second locking feature of the locking ring and the at least one first locking feature of the male component are in a staggered configuration.

8. The joint assembly of claim 1 , wherein the gasket further comprises a gasket body and a limiting projection extending from the gasket body to limit rotation of the locking ring relative to the male component.

9. The joint assembly of claim 1 , wherein:
the male component is fixedly coupled to a first sheet of the inflatable product that defines the first air chamber; and
the female component is fixedly coupled to a second sheet of the inflatable product that defines the second air chamber.

10. The joint assembly of claim 1 , wherein the inflatable product further comprises a multichannel air assembly having a first port and a second port, the first air chamber being in fluid communication with the first port via the joint assembly, and the second air chamber being in direct fluid communication with the second port.

11. An inflatable product assembly, the assembly comprising:
an inflatable product comprising at least a first air chamber with a first opening and at least a second air chamber with a second opening; and
a joint assembly comprising:
a male component fixedly coupled to the first opening of the first air chamber, the male component comprising a cap with a first protrusion and at least one first locking feature extending from the cap, the first protrusion and the cap defining a first conduit therethrough in fluid communication with the first air chamber;
a female component fixedly coupled to the second opening of the second air chamber, the female component comprising a head with a second protrusion extending from the head, the second protrusion and the head defining a second conduit therethrough in fluid communication with the second air chamber, wherein at least a portion of the second conduit is sized and shaped to receive the first protrusion of the male component, and wherein the head includes an annular recess defined by an outer wall and an inner wall;
a locking ring, the locking ring comprising a locking base sized to rotate in the annular recess of the female component, the locking ring further comprising at least one second locking feature configured to interact with the at least one first locking feature of the male component based on rotation of the locking ring; and
a gasket coupled to the female component to capture the locking ring in the annular recess.

12. The inflatable product assembly of claim 11 , wherein the joint assembly includes a locked configuration, in which the at least one second locking feature of the locking ring engages with the at least one first locking feature of the male component so that the first air chamber and the second air chamber are locked together.

13. The joint assembly of claim 11 , wherein the joint assembly includes an unlocked configuration, in which the at least one second locking feature of the locking ring and the at least one first locking feature of the male component are in a staggered configuration so that the first protrusion of the male component is removable from the second conduit of the female component and the first air chamber and the second air chamber are configured to be uncoupled.

14. The joint assembly of claim 11 , further comprising a multichannel air assembly having a first port and a second port, the first air chamber being in fluid communication with the first port via the joint assembly, and the second air chamber being in direct fluid communication with the second port.

15. The joint assembly of claim 14 , further comprising a hose that extends between the first port of the multichannel air assembly and the female component of the joint assembly.

16. The joint assembly of claim 11 , further comprising an air assembly having at least one port, the second air chamber being in direct fluid communication with the at least one port and the first air chamber being in fluid communication with the second air chamber via the joint assembly.

17. A method of assembling an inflatable product having a first air chamber and a second air chamber, the method comprising the steps of:
fixedly coupling a male component of a joint assembly to a first opening of a first air chamber, the male component comprising a cap with a first protrusion and a first locking feature extending from the cap, the first protrusion and the cap defining a first conduit therethrough in fluid communication with the first air chamber;
fixedly coupling a female component of the joint assembly to a second opening of a second air chamber, the female component comprising a head with a second protrusion extending from the head, the second protrusion and the head defining a second conduit therethrough in fluid communication with the second air chamber, wherein at least a portion of the second conduit is sized and shaped to receive the f
