Abstract
Description
Technical Field
[0001] This invention relates to an improved inflation valve assembly including a valve key. Specifically, this invention relates to a first inflatable camping assembly including a first inflation valve, a second inflatable camping assembly including a second inflation valve, and a valve key. Background Technology
[0002] Setting up tents, folding campervans (such as camping trailers), and camping accessories such as awnings and gazebos can be complex or time-consuming, especially when these structures require the assembly of multiple parts. These parts are susceptible to damage during assembly or use, such as from impacts or strong winds. To address these issues, these structures can include inflatable components, which can be inflated using a pump or other pressurized air source to complete the setup.
[0003] Inflatable assemblies may contain multiple inflation valves with individual plugs / seals. Users must manually place and secure these plugs into the valves to inflate the assembly. Therefore, users need to check that all inflation valves are properly closed before inflating. For large camping assemblies, unfolding an uninflated assembly and locating all inflation valves to check their closure can be difficult. This can delay the setup of the camping assembly, especially during inclement weather (such as rain), when interior walls / surfaces may become wet. Furthermore, users can easily overlook an inflation valve before starting to inflate, causing continuous air leakage during inflation, which is not only inefficient but may also take time for the user to discover the problem. This problem is particularly pronounced with new or unfamiliar camping assemblies, as users are unaware of the location and number of inflation valves. While using a single inflation / deflation valve ensures no air leakage during inflation, it can lead to longer deflation times because air can only escape from a single point. Additionally, air is more likely to stagnate, making it difficult to compactly store and / or pack the deflated assembly into a dedicated bag / container.
[0004] Additionally, inflation valves are typically designed for compatibility with any or multiple inflation devices / pumps. However, this compatibility with various accessories can compromise the seal and retention between the inflation device and the inflation valve, especially the seal between the pump adapter and the inflation valve. Users may need to continuously press the adapter into the valve or periodically push the adapter back into the inflation valve to maintain airflow.
[0005] One drawback of using inflatable components is that users must carry a pump or other pressurized air source to the campsite. For large inflatable structures (such as home inflatable tents), manual pumps may not be suitable, meaning an electric pump and power supply are also required, which can be bulky and noisy. Furthermore, when using multiple inflatable structures, independent pressurized air sources are needed, and these sources must be compatible with each inflatable structure in turn.
[0006] The object of this invention is to overcome at least one problem existing in the prior art, whether or not such problem is mentioned herein. Summary of the Invention

Preferably, in the non-operating position, the seal of the first inflation valve remains in place and preferably does not move due to the engagement of the valve key with the first inflation valve. Preferably, in the non-operating position, the seal of the first inflation valve remains or is maintained in the closed position.

[0011] Preferably, in the working position, the valve key keeps the seals of both the first and second inflation valves in the open position to form an air passage through the inflation valve assembly between the first and second inflation valves.
[0012] Preferably, when the valve key is engaged with only one inflation valve (and preferably disengaged from the other inflation valve), the seal of that inflation valve remains in the closed position. Preferably, when the valve key is engaged with only the first inflation valve (and preferably disengaged from the second inflation valve), the seal of the first inflation valve remains in the closed position.

[0022] Each inflation valve may include a latching device (or a blocking device) for holding the seal in an open position or a second open position. Preferably, the latching device prevents the seal from moving to a closed position; and in that position, the biasing device continuously biases the seal toward the closed position.
[0023] The latching device is manually operable; the user can engage the seal with the latching device by pressing a portion of the seal, preferably holding the seal in an open or second open position. The latching device can be manually unlocked from a locked state; the user can disengage the seal from the latching device by pressing a portion of the seal, allowing the seal to move to a closed position.

[0024] Each inflation valve may include a flow restrictor to limit the movement of the seal away from the inflation valve outlet opening. Therefore, the movement of the seal can be restricted between the sealing surface and the flow restrictor. The seal is restricted by the sealing surface in a first direction and by the flow restrictor in a second (opposite) direction. The flow restrictor may include one or more openings to allow airflow.
[0025] The biasing device may include a spring biasing structure, the spring biasing structure including a spring component for biasing the seal toward a closed position.
[0026] The biasing device (spring component) may include a shaft portion of the seal, the shaft portion being received within a channel defined by the inflation valve. The shaft portion may have an increasing diameter, and when the seal moves to the open position, the shaft portion moves into the channel, such that after the moving force is eliminated, the channel pushes the shaft portion back to the closed position.
[0027] The biasing device may include a single helical spring that can be accommodated between the proximal (upper) surface of the carrier and the distal (lower) surface of the current limiter.
[0028] The spring may include a resiliently deformable component.
[0029] The spring can be positioned around the central core of the carrier. Therefore, unless the reaction force is greater than the elastic force of the spring bias structure, the spring bias structure will hold the seal in the closed position.

The first longitudinal end may provide a first contact surface to actuate a first inflation valve (core component), and the second longitudinal end may provide a second contact surface to actuate a second inflation valve (core component). The actuating member is held within the valve key and is restricted to movement along the longitudinal axis of the valve key, preferably along the central longitudinal axis of the valve key.
[0033] The valve key may include a first separating surface and a second separating surface. The first separating surface may be provided by a first separating member, and the second separating surface may be provided by a second separating member. The valve key may define a retaining gap between the first separating member and the second separating member. The actuating member may include a retaining section that is restricted to movement between the first separating member and the second separating member. A portion or section of the actuating member may be configured to extend from the first separating member, and another portion or section of the actuating member may be configured to extend from the second separating member.
[0034] The valve key may include a biasing component for pushing the actuating member to a default position. The biasing component may include springs, preferably a first spring and a second spring. The first spring biases a first contact end (face) toward the default position, and the second spring biases a second contact end (face) toward the default position. Preferably, in the default position, the forces of the first spring and the second spring cancel each other out.
[0035] In the default position, the first and second contact surfaces are positioned to prepare to contact the abutment surfaces of the first and / or second inflation valves. Preferably, when a single abutment surface contacts a single contact surface, the actuating member is deviated from the default position, and the seal is held in the closed position. Preferably, when both abutment surfaces contact both contact surfaces simultaneously, the actuating member moves towards the default position, and both seals move towards the open position. Preferably, when both abutment surfaces contact both contact surfaces simultaneously, both seals are held and / or maintained in the open position.
[0036] The mating structure may include one or more mating grooves or openings and corresponding mating tabs.

The proximal (upper) surface of the seal may be made of a sealing material, such as an elastomeric material. The proximal (upper) surface may be configured to lower (or move away from) the sealing surface, allowing air to flow between the openings of the outlet, through the openings, and out of the inlet.
[0040] The inflation valve is set to be off by default.
[0041] According to a second aspect of the present invention, a camping assembly is provided, comprising a first inflatable camping assembly, a second inflatable camping assembly, and an inflation valve assembly, the inflation valve assembly comprising: A first inflation valve is disposed on the first inflatable camping assembly, the first inflation valve comprising: Entrance; Exports; and A seal movable between an open position and a closed position; the seal includes a sealing portion for preventing or allowing air to flow through the inflation valve between the inlet and the outlet; A second inflation valve is disposed on the second inflatable camping assembly, the second inflation valve comprising: Entrance; Exports; and A seal movable between an open position and a closed position; the seal includes a sealing portion for preventing or allowing air to flow through the inflation valve between the inlet and the outlet; Valve key; The valve key is configured to connect with the inlet of the first inflation valve and the valve key is configured to connect with the second inflation valve; when the valve key is connected to both the first inflation valve and the second inflation valve, the valve key is in the working position.

[0042] Preferably, the seal of the first inflation valve is biased from the open position to the closed position by a biasing device. Preferably, the seal of the second inflation valve is biased from the open position to the closed position by a biasing device.

Detailed Implementation
[0052] This invention provides an inflation valve assembly 10 for an inflatable camping assembly, which may include an awning, tent, or inflatable camping accessories (mattress, seat, furniture, etc.). The invention provides an assembly for transferring and / or supplying air between a first camping assembly and a second camping assembly, for example, supplying air from a main inflatable tent to an inflatable awning. Each camping assembly includes identical inflation valves, with a valve key configured to engage between two inflation valves. The valve key automatically opens both inflation valves, allowing air to be transferred between the two camping assemblies. Specifically, the valve key balances the pressure between the two camping assemblies. In some embodiments, the valve key may be configured to maintain a minimum pressure within one camping assembly to prevent the camping assembly from collapsing due to air supply. The valve key is configured to dock and engage with the first inflation valve, but this action does not open the inflation valve. The valve key must subsequently dock and engage with the second valve to simultaneously open both the first and second inflation valves, thereby creating a flow channel between the two inflatable camping assemblies to facilitate air transfer and supply.
[0053] Each inflation valve also includes a latching device for holding the seal in the open position (or a second open position). In the locked state, the latching device prevents the seal from moving to the closed position, and in this position, a biasing device continuously biases the seal toward the closed position. Therefore, when the valve key is not engaged with the inflation valve, the user can manually lock the seal in the open position to facilitate deflation. The inflation valve assembly includes a first inflation valve 20 having an inlet 22 and an outlet 24, and a second inflation valve 30 having an inlet 32 and an outlet 34.
[0054] To inflate the first inflatable camping component, an air source, in the form of a second inflatable camping component (air supply), needs to be connected. Specifically, the first inflation valve 20 is connected to the second inflation valve 30 via a valve key 60. For example, the first inflation valve 20 can be connected to an air chamber (inner tube) inside the tent pole, and the second inflation valve can be connected to an air chamber (inner tube) inside the awning pole. This connection allows the tent to inflate the awning (partially or fully).
[0055] Each inflation valve 20, 30 has an identical structure. Inflation valves 20, 30 include seals 26, 36 that seal the air passage between inlets 22, 32 and outlets 24, 34 to maintain air pressure within the respective chambers. However, each seal 26, 36 can be moved from a closed position to an open position. Seals 26, 36 are only in the open position when a valve key 60 is connected between the two inflation valves 20, 30. Therefore, the present invention provides a dedicated valve key 60 by which seals 26, 36 can be legally moved from the closed position to the open position. When the valve key 60 is not used, seals 26 remain in the closed position, which prevents or inhibits unauthorized deflation of the inflatable camping assembly. Furthermore, holding the valve key 60 between the two inflation valves 20, 30 allows for and promotes pressure equalization between the camping assemblies by keeping seals 26, 36 in the open position, eliminating the need for continuous manual operation of inflation valve components (e.g., manually keeping the pump adapter inside the inflation valve). This structure can maintain pressure for extended periods, ensuring that the camping units remain adequately inflated and / or pressure balanced throughout the day and under varying conditions, such as cold nights and hot days. For example, it may be possible to connect only one camping unit to another air source (the primary air source), and air from the pump can be transferred from the first camping unit to the second camping unit.
[0056] like Figures 1 to 5 As shown, a preferred embodiment of the valve assembly 10 includes a first inflation valve 20, a second inflation valve 30, and a dedicated valve key 60. The valve key 60 includes an actuator 61 (formed as a longitudinal member) for moving seals 26, 36 from a closed position to an open position. The valve key 60 and the inflation valves 20, 30 also include engagement means for engaging and holding the valve key 60 in a mating position relative to the first inflation valve 20 and the second inflation valve 30. Figure 1 and Figure 2 As shown, line 90 indicates that the airflow is cut off, and air is retained within the inflatable camping assembly. Due to the sealing structures 29 and 42, air cannot pass through the inflation valve 20. However, in Figure 3 In the middle, line 92 schematically represents airflow, indicating that air can flow freely through the first inflation valve 20, valve key 60 and the second inflation valve 30 (and vice versa), thereby realizing the transmission and delivery of air between the first inflatable camping component (equipped with the first inflation valve 20) and the second inflatable camping component (equipped with the second inflation valve 30).
[0057] The seals 26 and 36 of the inflation valves 20 and 30 include carriers 40 and 50 and flow restrictors 41 and 51, which fix the respective carriers 40 and 50 within their respective inlets 22 and 32. The seals 26 and 36 also include sealing portions, which in this embodiment are main seals 42 and 52. The main seals 42 and 52 are annular seals (e.g., resilient O-ring seals) configured to seal on corresponding sealing surfaces 29 and 39 defined around the openings 25 and 35 of the outlets 24 and 34. In the closed position, the main seals 42 and 52 seal on the sealing surfaces 29 and 39 provided by the valve housings 28 and 38 of the inflation valves 20 and 30. The main seals 42 and 52 are both fixed to the outer periphery (circumference) of the disc-shaped carriers 40 and 50.
[0058] Inflation valves 20 and 30 include biasing devices in the form of helical springs 23 and 33 arranged around central shafts 48 and 58 (core members) for actuating seals 26 and 36 toward sealing surfaces 29 and 39. Specifically, this biasing structure causes the main seals 32 and 33 to seal onto sealing surfaces 29 and 39. Helical springs 23 and 33 are constrained between the holding surface of the carrier and end faces 21 and 31 within the inlets 22 and 32 of the inflation valves 20 and 30. In a preferred embodiment, flow restrictors 41 and 51 include shafts (or core members) extending from the disc-shaped portion of the carriers 40 and 50, extending through the inlet end faces 21 and 31 of the inflation valves 20 and 30. The inlet end faces 21 and 31 have holes or channels in the disc-shaped partitions forming the end faces, the holes allowing the shafts 48 and 58 to slide therein. Heads 46 and 56 are provided at the upper distal ends of the shafts 48 and 58, the heads including enlarged heads or radial flanges. If the diameter or circumference of the enlarged head is too large, it cannot pass through the hole. Therefore, the enlarged heads 46, 56 form annular surfaces or retaining surfaces 43, 53, which directly oppose the upper / distal surfaces of the inlet end faces 21, 31. These two opposing surfaces are used to clamp or confine the springs 23, 33 therebetween (as will be further explained below), thereby pressing the seals 32, 33 against the sealing surfaces 29, 39.
[0059] The flow restrictors 41 and 51 of the inflation valves 20 and 30 also restrict the movement of the seals 26 and 36. Specifically, the flow restrictors 41 and 51 prevent the seals 26 and 36 from detaching from the housings 28 and 38. The retaining surfaces 43 and 53 formed by the flow restrictors 41 and 51 are directly opposite to the outer surfaces of the end faces 21 and 31 of the inflation valves 20 and 30 (located in the inlets 22 and 32). Therefore, the seals 26 and 36 are constrained to move only between the sealing surfaces 29 and 39 (closed position) and the restricted positions spaced apart from the sealing surfaces 29 and 39, thereby creating a gap that allows air to flow around the seals 26 and 36 (e.g., ...). Figure 3(As shown). Flow restrictors 41 and 51 are fixed within the inlets 22 and 32 of valve housings 28 and 38. Flow restrictors 41 and 51 include a central shaft with an upper (distal) head or flange. The head (or flange) forms surfaces 43 and 53 to engage with helical springs 23 and 33, as described above. Furthermore, the upper distal surface of the head forms a contact surface for actuating the inflation valves 20 and 30, as described below. In one embodiment, the shaft consists of two parts to first fit the helical springs 23 and 33 onto the lower component, and then engage and connect with the upper component including the head, thereby securing the helical springs 23 and 33 in place. These two components constituting the shaft can be fixed together by a press-fit structure.
[0060] Each inflation valve includes a manually operable latching device. A user can engage the latching device by pressing a portion of the seals 26, 36, thereby preferably holding the seals 26, 36 in an open position or a second open position. For example, when the seals 26, 36 are not locked and are not pressed by the valve key 60 (or any other external force), the seals 26, 36 are held in the closed position; when held in the open position by the valve key 60, it is a first open position; and when held by the latching device, it is a second open position. In both open positions, the biasing device (springs 23, 33) is continuously biased and pushes the seals 26, 36 back to the closed position. The latching device can be manually unlocked from the locked state by the user pressing a portion of the seals 26, 36 (e.g., heads 46, 56) to disengage the seals 26, 36 from the latching device, thereby moving the seals 26, 36 to the closed position. The latching device includes a latching element in the form of an annular assembly 75. The annular assembly 75 engages with irregularly shaped surfaces on the first portion 74 and the second portion 76 of the flow restrictors 41 and 51. Each irregularly shaped surface includes a series of gaps or grooves into which the annular member 75 (or a portion of the annular member) engages or disengages with the seals 26 and 36 in a locked (open or second open) position. The latching device cannot be operated by the valve key 60. Specifically, the engagement of the valve key 60 within the inflation valves 20 and 30 does not trigger the latching device. The valve key 60 only partially pushes the flow restrictors 41 and 51 toward the latching device, preventing the latching device from locking the seals 26 and 36, which remain unlocked. Specifically, when the user presses the flow restrictors 41 and 51 inward, a portion of the seals 26 and 36 creates resistance, indicating that the fully pressed position has been reached; when the user releases the pressure, the seals 26 and 36 remain locked in the open (or second open) position. When valve key 60 is engaged, the seals do not reach the fully pressed position, but only move partially towards it, thus the latch is not triggered. Upon removal of valve key 60, since no latch or other obstruction holds seals 26, 36 in the open or second open position (or any open position), seals 26, 36 immediately and automatically return to the closed position (via biasing devices in the form of springs 23, 33). In the locked position, the biasing devices (springs 36, 33) continuously bias seals 26, 36 towards the closed position.
[0061] like Figure 4 As shown, the shaft of seal 26 (or 36) includes a first (upper distal) portion 74 and a second (lower / proximal) portion 76. These portions mate with an annular member 75 to form a latching or engaging mechanism, assisting in holding seal 26 in the open position (e.g., Figure 5(As shown). This retaining mechanism assists in venting. It is understood that when seal 26 is pushed inward (downward), seal 29 disengages from the corresponding sealing surface on the valve, thereby allowing fluid flow, such as for inflation or deflation. Therefore, since the engagement of valve key 60 with a single valve does not hold seal 26 in this position, the flow restrictor 41 is equipped with a manually operable latching mechanism. During venting, the flow restrictor 41 could be manually pressed, but the latching mechanism eliminates this laborious manual operation.
[0062] The upper part 74 is a fixed component and will not twist or rotate. When the entire seal 26 is pressed downwards, the upper part 74 contacts the annular part 75, causing the annular part 75 to twist. When the downward force pressing the seal 26 is released (e.g., the user releases their finger), the annular part 75 engages in a groove on the lower part 76. The groove on the lower part 76 determines whether the lower part is sealing or opening the valve by determining the height of the lower part 76 within the valve. The grooves are arranged in an alternating sequence, for example, groove 1 = valve open, groove 2 = valve closed, groove 3 = valve open, groove 4 = valve closed. The spring 23 pushes the upper part 74 upwards, forcing the annular part 75 to engage in the next groove, thus determining the open or closed state of the valve. Each time the seal 26 is pressed, the annular part 75 continues to rotate in the same direction. The latching mechanism will not be activated by the valve key 60 because the valve key 60 will not press the flow restrictors 41, 51 to the depth of engagement with the annular member 75. Therefore, after the valve key 60 is released, the inflation valves 20, 30 (seals 26, 36) will return to the closed position.
[0063] The inflation valves 20 and 30 are formed as a single component / part or an integrated device (self-supporting), and the seals 26 and 36 are constrained to translate only between the open and closed positions. As described above, due to the thrust of the springs 23 and 33 or other biasing devices, the seals 26 and 36 will bias toward the closed position unless a reaction force overcomes the springs 23 and 33 or the biasing force. This reaction force can be generated by contacting and abutting with the actuator 61 provided by the valve key 60. However, as described below, this force requires the valve key 60, and in particular the actuator 61, to be clamped and / or engaged between the flow restrictors 41 and 51 of the two inflation valves 20 and 30. Each inflation valve 20 and 30 may include a receiving portion 45 and 55, which may be connected via a structure such as threads on the main body of the housing 28 and 38. The receiving portions 45 and 55 may form an inlet surface and an inlet end face 21 and 31. The disassembly and assembly of the receiving part facilitates the assembly of the inflation valves 20 and 30, and also facilitates the positioning of the seals 26 and 36 in the constrained position within the inflation valves 20 and 30.
[0064] The valve key 60 includes a body 62 having a peripheral wall 64 and a plurality of holes 66 formed in a partition plate; the partition plate may be formed by two separating members 68, 69 to form a channel through the body 62. The separating members 68, 69 may include a series (e.g., three, four or more) of radial spokes extending outward from an inner annular member or ring. The peripheral wall 64 is configured to engage within the outer walls 27, 37 of the inlets 22, 32 of the inflation valves 20, 30.
[0065] The inflation valve assembly 10 includes an engagement device for engaging the valve key 60 in a mating position relative to the first inflation valve 20 and / or the second inflation valve 30 (e.g., Figure 3 As shown below, in order for the inflation valve assembly 10 to operate (so that air can be transmitted and supplied from the first inflation camping assembly to the second inflation camping assembly), the valve key 60 must mate (and preferably engage) with both the first inflation valve 20 and the second inflation valve 30.
[0066] The valve key 60 includes engaging means in the form of elastic tabs 72 to achieve engagement / buttock function. Specifically, the peripheral wall 64 of the valve key 60 is provided with a first pair of elastic tabs 72 for engaging with the first inflation valve 20, and a second pair of elastic tabs 72 for engaging with the second inflation valve 30. The first pair of tabs 72 are disposed toward a first end of the valve key 60 (for engaging with the first inflation valve 20), and the second pair of tabs 72 are disposed toward a second opposite end of the valve key 60 (for engaging with the second inflation valve 30). The inflation valves 20 and 30 include engaging means in the form of openings 44 and 54 or recesses. Specifically, each inflation valve 20 and 30 is provided with two openings 44 and 54, which are offset by 180 degrees around the outer wall or peripheral wall 27 and 37 of the inlet 22 and 32. In some embodiments, four openings 44, 54 may be provided, each staggered by 90 degrees, to facilitate engagement of the valve key 60—because the two resilient tabs 72 can engage in two different pairs of openings 44, 54. For example, the valve key 60 can be first inserted into inlets 22, 32, and then rotated until the tabs 72 engage in the nearest pair of openings 44, 54. By providing four openings 44, 54 instead of two, this rotational action can be reduced.
[0067] In an alternative embodiment, the mating / engagement structure includes a bayonet mechanism, wherein the inflation valve includes one, two, or more slots for engaging with one, two, or more lugs disposed on the outer / outer surface of the valve key, and vice versa. As a further alternative, the mating / engagement structure includes a threaded mechanism, wherein one of the valve key, the first inflation valve, and / or the second inflation valve includes external threads, and the other includes internal threads. The mating structure may employ an interference fit.
[0068] The valve key 60 is positioned within the openings of inlets 22 and 32, thereby forming a seal between the valve key 60 and the inflation valves 20 and 30. In this position, the valve key 60 engages and mates with both inflation valves 20 and 30 simultaneously, thus the valve key 60 is in the working position. The valve key 60 is configured to mate first with the inlet 22 of the first inflation valve 20, and then with the second inflation valve 30. The valve key 60 is only in this working position when it mates with both the first and second inflation valves 20 and 30 simultaneously. The engagement and mate of the valve key 60 with the two inflation valves 20 and 30 is configured to move both seals 26 and 36 of the first and second inflation valves 20 and 30 to the open position when in this working position. In the working position, the valve key 60 holds the seals 26 and 36 of the first and second inflation valves 20 and 30 in the open position, thereby forming an air passage through the inflation valve assembly between the first and second inflation valves 20 and 30. In use, valve key 60 first mates and engages with the first inflation valve 20, but this does not move seal 26 to the open position; the first inflation valve 20 remains closed. Valve key 60 then mates and engages with the second inflation valve 30, causing seals 26 and 36 of both the first and second inflation valves 20 and 30 to move to the open position. Therefore, this fail-safe connection sequence prevents air loss and ensures a reliable and efficient transfer / supply of air from the first inflatable camping assembly to the second inflatable camping assembly. The mechanism for achieving this sequential connection and opening of seals 26 and 36 will now be described.
[0069] The actuator 61 of the valve key 60 forms a first contact surface 88 and a second contact surface 89. Each contact surface 88, 89 is positioned to contact and abut against the abutment surface provided by the flow restrictors 41, 51 of the inflation valves 20, 30.
[0070] An actuating member in the form of actuator 61 is translatably movable within the body of valve key 60. As described above, in a preferred embodiment, valve key 60 includes a body 62 having a peripheral wall 64 and a plurality of holes 66 formed in two separator members 68, 69 to form a channel through the body 62. Separator members 68, 69 include three radial spokes extending outward from an inner annular member or ring. Valve key 60 defines a retaining gap between the first separator member 68 and the second separator member 69. Actuator 61 includes a retaining section 80, which is restricted to movement between the first separator member 68 and the second separator member 69. A first portion or section 82 of actuating member 80 is configured to pass through and / or extend beyond the first separator member 68, and another (second) portion or section 83 of actuating member 80 is configured to pass through and / or extend beyond the second separator member 69. Thus, actuator 80 is constrained to perform limited translational movement within the body 62 of valve key 60. This translational movement allows the opposing end faces (contact surfaces 88, 89) to extend into or retract into the body 62 of the valve key 60. This movement occurs along the longitudinal axis of the valve key 60 body, preferably along the central longitudinal axis. However, the distance between the two contact surfaces 88, 89 remains fixed, which in turn allows the flow restrictor 41 of the first inflation valve 20 to move the flow restrictor 51 on the second inflation valve 30 in the operating position.
[0071] like Figure 6 and Figure 7 As shown, the actuator 60 within the valve key can translate freely within the valve key body. In an alternative embodiment, the valve key 60 includes a biasing component for pushing the actuator 61 to a default position, such as... Figure 8 and Figure 9 As shown. The biasing assembly includes a first spring 86 and a second spring 84. The first spring 86 biases the first contact end / contact surface 88 toward a default position, and the second spring 84 biases the second contact end / contact surface 89 toward a default position. In the default position, the forces of the first spring 86 and the second spring 84 cancel each other out. For example, in the absence of external force, the actuator 61 is in the default position. Each spring 84, 86 is constrained to act between the inner surface of the separating members 68, 69 and the retaining surface provided by the retaining section 80 of the actuator 61. Thus, each helical spring 84, 86 pushes and attempts to move the corresponding section 82, 83 and the associated contact surface 88, 89 outward.
[0072] In the default position, the first contact surface 88 and the second contact surface 89 are positioned to prepare to contact the abutment surface 47 of the first inflation valve 20 and / or the abutment surface 57 of the second inflation valve 30. When the first abutment surface 47 contacts the first contact surface 88, it causes the actuator 61 to deviate from the default position and holds the seal 26 in the closed position. When both abutment surfaces 47 and 57 contact both contact surfaces 88 and 89 simultaneously, it moves the actuator 61 back to the default position and moves both seals 26 and 36 to the open position. When both abutment surfaces 47 and 57 contact both contact surfaces 88 and 89 simultaneously, they hold and / or maintain both seals 26 and 36 in the open position. This position is maintained by engagement mechanisms provided by the tab 72 and the openings 44 and 54.
[0073] In use, valve key 60 is mated and engaged with the first inflation valve 20 of the first inflatable camping assembly. The first inflatable camping assembly can be fully inflated and / or connected to a pump via a separate pump inflation valve. This allows the first inflatable camping assembly to act as a supply unit (by providing an air reserve, which can be replenished by the pump alone or not) to supply air to the second inflatable camping assembly. Connecting only the first inflation valve 20 does not cause the seal 26 to move to the open position; the first inflation valve 20 remains closed. The second inflation valve 30 is then engaged with the second free end of valve key 60, specifically, valve key 60 is mated and engaged with the second inflation valve 30. This causes the flow restrictor 51 of the second inflation valve 30 to push actuator 61 inward toward the body 62 of valve key 60, which causes the other end of actuator 61 to move outward (towards the first inflation valve 20), thereby moving the seal 26 of the first inflation valve 20 to the open position. Simultaneously, the reaction force generated by the flow restrictor 41 of the first inflation valve 20 overcomes the spring force in the second inflation valve 30, causing the seal 36 of the second inflation valve 30 to move to the open position. In this operating position, all springs are balanced, causing the actuator 61 to be essentially in the default position, and both seals 26 and 36 to be in the open position.
[0074] After the valve key 60 is removed from one of the inflation valves 20, 30, the actuator 61 will move away from the remaining connected inflation valve, thereby closing that inflation valve. Specifically, the relatively free movement of the actuator 61 will move the seal to the closed position. Therefore, the inflation valve assembly 10 can provide an automatic and fail-safe closing operation when the two inflatable camping assemblies are disconnected from each other.
[0075] The foregoing describes a preferred embodiment, but it should be understood that various modifications can be employed while retaining the functional operation of the invention. For example, the docking and engagement mechanism may include other connecting mechanical structures and / or magnetic structures, etc. Similarly, the seal may be pushed and / or held in the closed position by other mechanical structures and / or magnetic mechanisms, etc.
[0076] It is understood that other valve keys or accessories can open the inflation valve without using a second inflation valve. For example, a pump with suitable accessories will move the seal to the open position, allowing the pump to inflate the inflatable camping assembly. Therefore, this eliminates the need for two inflatable camping assemblies with valve keys joined in the middle.
[0077] Similarly, when valve key 60 engages only with a single inflation valve 20, 30, the user can press the actuator 61 in valve key 60 to open or close inflation valves 20, 30. As described above, the latching device is configured such that: the first press triggers the latching device to engage and hold seal 26 in the open position; the second press disengages the latching device, and seal 26 moves back to the closed position. The latching device is located on seal 26, specifically implemented by the movement of flow restrictor 41. As described above, the grooves of the latching structure are arranged in an alternating sequence, for example, groove 1 = valve open, groove 2 = valve closed, groove 3 = valve open, groove 4 = valve closed. Each press of flow restrictor 41 (to the fully pressed position or a predetermined position / depth) moves annular member 75 to the next groove, thereby determining the open / closed state of the valve. Each time seal 26 is pressed, annular member 75 continues to rotate in the same direction. Therefore, the user can press the actuator 61 of the engaged valve key 60 once to open the inflation valve 20, and press the actuator 61 again to subsequently close the inflation valve 20. This can help during deflation while keeping the valve key 60 in a safe and engaged position.
[0078] This invention sets the valves to a default closed state and keeps them closed until the valve key engages between two such inflation valves; therefore, the valves are always ready when the camping structure is unpacked, eliminating the need to manually close each valve before inflation. This configuration allows the inflation valves to be closed without user intervention, such as eliminating the need for plugs on the valves. The valve key prevents malicious deflation and facilitates the implementation of the air supply system.
[0079] In another embodiment, such as Figure 10 As shown, the inflation valve 20 includes a biasing device (spring 23) for pushing the seal 26 to the open position rather than the closed position. In this configuration, a latching device is provided for locking the seal 26 in the closed position. These latching devices may be in the form of annular elements and cooperate with the two parts of the flow restrictor 41, as described above, only in opposite directions.
[0080] In this configuration, when seal 26 is in the open position, valve key 60 will mate and engage with the first inflation valve 20 as previously described, without affecting the position / function of seal 26. Valve key 60 will then mate and engage with the second inflation valve 30 as previously described, ensuring that both seals are in the open position (if they are not already in that position), and valve key 60 also holds seals 26 and 36 in the open position. This open position can be a second open position, different from the original (first) open position of seal 26. When valve key 60 is removed, seal 26 moves to the closed position. For example, valve key 60 moves seal 26 to the closed position, and then valve key 60 is pulled out. This movement can be caused by the engagement between valve key 60 and seal 26. In one embodiment, a magnetic structure is provided to allow valve key 60 to move seal 26 to the closed position. For example, valve key 60 may have a first magnetic element (located at one end of actuator 61), and seal 26 may have a corresponding magnetic element (located at the distal end / head 46 of flow restrictor 41). Other mechanisms and devices may also be used to achieve this movement of seal 26 when valve key 60 is removed. Thus, through this engagement, seal 26 is pulled to the closed position against the biasing force of spring 23. In the closed position, a latching device holds seal 26 in the closed position. This latching structure can be unlocked by subsequently mating valve key 60 between the two inflation valves 20, 30, or manually unlocked by the user moving the flow restrictor (e.g., pulling or pushing the flow restrictor depending on the configuration of the latching device).
[0081] In one example, the latching device can be disengaged from the latched state (seal 26 is in the closed position) by pushing the flow restrictor downward. This can be done manually by the user: grasp the head 46 of the flow restrictor 41 and push the flow restrictor to unlock seal 26 from the closed position. Alternatively, the action of mating valve key 60 between the two inflation valves 20, 30 is configured to push the flow restrictor 41 downward. This downward movement disengages the latching device, and the biasing structure (spring 23) moves seal 26 to the open position. This unlocking operation can also be done manually by the user: push the head 46 of the flow restrictor 41 to unlock seal 26 from the closed position. In another example, the latching device can be disengaged from the latched state (seal 26 is in the closed position) by pulling the flow restrictor upward. This can be done manually by the user: grasp the head 46 of the flow restrictor 41 and pull the flow restrictor to unlock seal 26 from the closed position. Alternatively, valve key 60 may have an actuation mechanism that pulls / moves flow restrictor 41 upward when valve key 60 is mated and / or engaged between the two inflation valves 20, 30. The actuation mechanism may include a lever or magnetic device for pulling flow restrictor 41 upward, and this actuation mechanism functions only when valve key 60 is mated / engaged between the two inflation valves 20, 30.
