The present application relates generally to toys and, in particular, to a toy vehicle playset with channels to direct liquid off the toy vehicle playset.
Toys provide entertainment for different users, such as children. For example, a toy may include various features with which a child may play. An example toy that may entertain a child is a toy vehicle, which may emulate the appearance, movement, and/or feel of a real-world vehicle. New toys with new features, such as liquid play features that allow a toy vehicle to interact with liquid, can provide added play value and provide additional entertainment. However, the liquid play feature may cause the liquid to flow and distribute in a manner that may be difficult to clean or remove.
A toy playset is presented herein. According to one example embodiment, the toy playset includes a first base portion having a first channel and an outlet, as well as a second base portion having a second channel. The first channel is configured to receive a liquid and direct the liquid to the outlet, and the outlet is configured to direct the liquid off the toy playset. The first base portion and the second base portion are configured to move relative to one another to transition the toy playset between a first configuration and a second configuration, and the first channel and the second channel are fluidly coupled to one another in the second configuration such that the second channel is configured to direct liquid toward the outlet via the first channel.
Other systems, methods, features, and advantages will be, or will become, apparent to one with skill in the art upon examination of the following figures and detailed description. All such additional systems, methods, features, and advantages are included within this description and are within the scope of the claimed subject matter.
The toy playset presented herein may be better understood with reference to the following drawings and description. Unless dimensions of elements of the drawings are specifically called-out and described herein, it should be understood that the elements in the figures are not necessarily to scale and that emphasis has been placed upon illustrating the principles of the toy playset. In the figures, like-referenced numerals designate corresponding parts throughout the different views.
Overall, a toy vehicle playset is presented herein. The toy vehicle playset includes a track configured to receive a toy vehicle and direct movement of the toy vehicle through at least a portion of the playset. The toy playset also includes a liquid play feature that can interact with the toy vehicle. For example, the liquid play feature may include a container configured to hold a liquid, and the toy vehicle may be positioned within the container to contact (e.g., be submersed in) the liquid. Moreover, the toy playset includes a channel configured to direct liquid off the toy playset. For instance, liquid may spill from the container and/or be carried by the toy vehicle onto another part of the toy playset, and in these instances, the channel receives the spilled/carried liquid and directs the liquid in a controlled manner (e.g., in a single direction off the toy playset), such as toward an outlet. Thus, the channel allows the liquid to be easily and efficiently cleaned (e.g., removed) from the toy playset, such as by preventing or at least discouraging unwanted and uncontrolled flow of the liquid (e.g., in multiple directions off the toy playset).
The toy playset 100 also includes one or more liquid play features 109 that may interact with the toy vehicle 104. For example, each liquid play feature 109 may include a container in which liquid is stored. In such instances, the container may be configured to receive the toy vehicle 104, thereby placing the toy vehicle 104 in contact with (e.g., by at least partially submersing the toy vehicle 104 within) the liquid. As an example, exposure of the toy vehicle 104 with the liquid via the liquid play feature 109 may provide a car wash simulation and/or a path obstacle to enhance the entertainment provided by the toy playset 100. As other examples, the liquid play feature could be or include sprayers, sprinklers, fountains, showers, or any other type of feature capable of introducing liquid to the toy playset 100.
In some embodiments, the liquid play feature(s) 109 is configured to be coupled to the base 102. For example, the base 102 may include a first receptacle 110 in which a liquid play feature 109 (e.g., the container) may be positioned. Positioning of the liquid play feature 109 in the first receptacle 110 may, for example, position the liquid play feature 109 adjacent to the first base track 108. Thus, the liquid play feature 109 may be within the path of travel of the toy vehicle 104 along the first base track 108. Consequently, traversal of the toy vehicle 104 along the first base track 108 may cause the toy vehicle 104 to interact with the liquid play feature 109. However, in other embodiments, the base 102 need not include a receptacle 110 and may support a liquid play feature 109 in any desirable manner.
Interaction between the toy vehicle 104 and the liquid play feature 109 may cause liquid to spill from the liquid play feature 109 (e.g., from the container) onto the base 102, such as onto the first base track 108. The base 102 therefore includes a first channel 112 configured to direct the liquid in a controlled manner along the base 102. By way of example, the first channel 112 may receive the liquid spilled from the liquid play feature 109 and direct the liquid toward an outlet 114 configured to discharge the liquid off the base 102 and out of the toy playset 100. Thus, the first channel 112 may control liquid flow along the base 102, such as in a predictable manner toward the outlet 114, to prevent or at least discourage flow of liquid off the toy playset 100 in various, uncontrolled/unpredictable directions and/or locations. For this reason, the first channel 112 and the outlet 114 may enable the liquid to be cleaned more easily/efficiently from the toy playset 100 (e.g., by collecting liquid at a single drainage point adjacent to the outlet 114).
In certain embodiments, the first channel 112 is formed into the first base track 108. Thus, liquid spilled onto the first base track 108 (e.g., liquid carried by the toy vehicle 104 onto the first base track 108) may be directed into the first channel 112 and subsequently directed toward the outlet 114. In additional or alternative embodiments, the first receptacle 110 is fluidly coupled to the first channel 112. Thus, the liquid may flow through the first receptacle 110 and/or the first channel 112 toward the outlet 114.
The base 102 may also include multiple portions configured to move relative to one another in some embodiments. For example, the base 102 may include a second portion 116 configured to move (e.g., rotate) relative to the first portion 106. The second portion 116 may include a second base track 118 configured to receive the toy vehicle 104 and direct movement of the toy vehicle 104 along the second portion 116. The second portion 116 may also include a second receptacle 120 in which an additional liquid play feature 109 may be positioned to couple to the base 102. The second portion 116 may further include a second channel 122 configured to direct liquid in a controlled manner along the base 102. For instance, the second channel 122 may be formed into the second base track 118 and/or may be fluidly coupled to the second receptacle 120.
In some embodiments, the first portion 106 and the second portion 116 are movable relative to one another to transition the toy playset 100 between a first configuration and a second configuration. In the first configuration, which may be a play configuration, the first base track 108 and the second base track 118 are engaged with one another such that the toy vehicle 104 may readily move between the first base track 108 and the second base track 118. As such, the first configuration of the toy playset 100 may enable the toy vehicle 104 to move along the base 102 to provide a more interactive experience. In the second configuration, which may be a storage/transport configuration, the second channel 122 and the outlet 114 may be fluidly coupled to one another. By way of example, the second channel 122 may direct liquid toward the outlet 114 via the first channel 112. Consequently, the second configuration may enable the liquid to be readily directed to the outlet 114 from each of the first portion 106 and the second portion 116. In other words, the first channel 112 and the second channel 122 may direct liquid to a common location at the outlet 114. Therefore, liquid spilled onto the base 102 (e.g., onto different parts of the base 102, including the first portion 106 and the second portion 116) from the liquid play feature(s) 109 may be more easily cleaned or collected (e.g., at the outlet 114) from the toy playset 100 in the second configuration. In certain embodiments, the first base track 108 and the second base track 118 are disengaged with one another in the second configuration, and/or the outlet 114 and the second channel 122 are fluidly separate from one another in the first configuration.
To secure the toy playset 100 within the second configuration, the first portion 106 may include an extension 124 and the second portion 116 may include a recess 126. In the second configuration, the first portion 106 and the second portion 116 are oriented to insert the extension 124 into the recess 126 such that the second portion 116 captures the extension 124 within the recess 126 to block relative movement between the first portion 106 and the second portion 116. Accordingly, insertion of the extension 124 within the recess 126 maintains the toy playset 100 in the second configuration. As a result, liquid may be more controllably directed along the base 102 (e.g., to avoid unwanted spillage of liquid from the second channel 122 otherwise caused by unwanted movement of the second portion 116 relative to the first portion 106 to fluidly decouple the second channel 122 from the outlet 114). In additional or alternative embodiments, the second portion 116 may include an extension and the first portion 106 may include a recess configured to block relative movement between the first portion 106 and the second portion 116. In further embodiments, the first portion 106 and the second portion 116 may include any other suitable features to secure the toy playset 100 in the second configuration.
It should be noted that the base 102 may include any quantity of movable portions in alternative embodiments. As an example, the base 102 may include a single portion. Indeed, the second portion 116 may be optional, and the base 102 may include the first portion 106 and not the second portion 116. As another example, the base 102 may include more than two portions that are movable relative to one another, such as to arrange the portions in a manner to enable liquid to be directed along each portion toward a common location (e.g., the outlet 114 of the first portion 106).
The adjustable component 204 is coupled to the base 102 and is configured to move relative to the base 102. For instance, the adjustable component 204 may be moved manually. As such, the adjustable component 204 includes a handle 210 that is able to be grasped by the user to help the user provide a sufficient amount of force that causes the adjustable component 204 to move relative to the base 102. As an example, movement of the adjustable component 204 relative to the base 102 may orient the secondary track 206 in different manners to enable receipt of the toy vehicle 104 from the first liquid play feature 202 and/or to direct the toy vehicle 104 to the second liquid play feature 208. As another example, movement of the adjustable component 204 may orient the adjustable component 204 to direct liquid off the adjustable component 204, such as toward the outlet 114 (
The toy playset 250 also includes a first liquid play feature 266 that is couplable to the first portion 256, as well as a second liquid play feature 268 that is couplable to the second portion 258. For instance, the first liquid play feature 266 may be configured to be positioned in a first receptacle 270 of the first portion 256, and the second liquid play feature 268 may be configured to be positioned in a second receptacle 272 of the second portion 258. Additionally, the toy playset 250 includes an adjustable component 274 coupled to the first portion 256. The adjustable component 274 includes a secondary track 276, and at least part of the secondary track 276 is configured to extend toward a section of the first base track 262 and into the first liquid play feature 266 positioned in the first receptacle 270. The adjustable component 274 also includes a handle 278 for grasping by a user to facilitate movement of the adjustable component 274 relative to the base 254.
Contact between the toy vehicle 302 and the liquid held in the first liquid play feature 266 may cause the toy vehicle 302 to carry some liquid. Thus, movement of the toy vehicle 302 from within the first liquid play feature 266 to the adjustable component 274 may cause the toy vehicle 302 to carry liquid from the first liquid play feature 266 to the adjustable component 274, such as along the secondary track 276. The toy playset 250 includes features to direct such liquid from the adjustable component 274 toward the first liquid play feature 266. By way of example, the adjustable component 274 is coupled to a support 402 of the base 254, and the secondary track 276 of the adjustable component 274 is configured to direct liquid to the support 402 (e.g., via a gravitational force). The support 402 defines a passage 404 (e.g., a channel) configured to receive liquid from the secondary track 276, and the support 402 is oriented (e.g., sloped toward the first liquid play feature 266) to direct liquid along the passage 404 and into the first liquid play feature 266, such as via a gravitational force. As such, the passage 404 directs liquid in a controlled manner to avoid unwanted flow of liquid along the toy playset 250 (e.g., away from the first liquid play feature 266).
Furthermore, directing liquid into the first liquid play feature 266 via the support 402 may help readily replenish the supply of liquid within the first liquid play feature 266. That is, the toy vehicle 302 may carry liquid out of the first liquid play feature 266 to the adjustable component 274 to initially reduce a supply of liquid within the first liquid play feature 266. However, the support 402 directs liquid from the secondary track 276 back into the first liquid play feature 266 to increase the supply of liquid within the first liquid play feature 266. Thus, the amount of liquid within the first liquid play feature 266 may be substantially maintained or at least reduced more slowly to enable continued play of the toy playset 250 (e.g., without having to manually replenish the supply of liquid within the first liquid play feature 266). However, to be clear, the support 402 need not be the only component to provide such replenishment paths. In other embodiments, replenishment paths might be included in any desirable part, portion, feature, etc. of a playset.
As mentioned, when a user plays with playset 250, liquid may spill from the first liquid play feature 266 and/or from the second liquid play feature 268 onto the base 254. For this reason, the base 254 includes channels to direct such liquid in a controlled manner, such as toward a common location.
The first portion 256 also includes an outlet 604 configured to direct liquid off the toy playset 250, as well as a second channel 606 (e.g., a discharge channel) fluidly coupling the first receptacle 270 and the outlet 604 to one another. The first receptacle 270 is sloped toward the second channel 606 to encourage liquid flow to the second channel 606 via a gravitational force, and the second channel 606 is sloped from the first receptacle 270 toward the outlet 604 to encourage liquid flow through the second channel 606 and to the outlet 604. Thus, liquid collected in the first receptacle 270, such as liquid received from the first channel 600 is encouraged to flow out of the toy playset 250 via the outlet 604. In other words, the first receptacle 270, the first channel 600, the first branch segment 602, and the second channel 606 collectively direct liquid to the outlet 604. Accordingly, liquid (e.g., liquid carried by the toy vehicle 302 onto the first base track 262) may be directed from different parts of the first portion 256 to the same common location at the outlet 604 to control liquid flow along the first portion 256 and facilitate cleaning of the liquid from the toy playset 250 (e.g., via discharge of the liquid off the toy playset 250 via the outlet 604). However, to reiterate, other embodiments need not include the depicted sloping and can include or not include any desirable features that encourage flow towards the outlet 604 (e.g., with backpressure of liquid accumulation and/or tilting of the toy playset 250 causing flow).
Moreover, in the depicted embodiment, the passage 404 of the support 402 directs liquid from the adjustable component 274 toward the first receptacle 270, such as into the first liquid play feature 266 positioned within the first receptacle 270. The first receptacle 270 may receive some of the liquid directed through the passage 404, such as liquid that does not flow into the first liquid play feature 266. As such, the liquid may also be directed from the adjustable component 274 toward the outlet 604 via the first receptacle 270.
A fourth channel 654 is formed into a part of the bypass track 550 and is fluidly coupled to the second receptacle 272 to direct liquid into the second receptacle 272. For example, the fourth channel 654 may extend along the bypass track 550 to an opening 656 formed through the bypass track 550, and a third branch segment 658 is fluidly coupled to the opening 656 and to the second receptacle 272. Thus, liquid may flow along the fourth channel 654, into the opening 656, through the third branch segment 658, and into the second receptacle 272 (e.g., via a gravitational force). As such, the third channel 650, the second branch segments 652, the fourth channel 654, the opening 656, and the third branch segment 658 collectively direct liquid to the second receptacle 272. Accordingly, liquid (e.g., liquid carried by the toy vehicle 302 onto the second base track 264) may be directed from different parts of the second portion 258 to the second receptacle 272.
In the first configuration 252 (
The second portion 258 also includes additional channels configured to direct liquid toward the extension 700. As an example, the second portion 258 may include a reservoir 704 configured to receive liquid from another part of the toy playset 250, such as from the adjustable component 274 and/or from the second liquid play feature 268, and to direct liquid toward the extension 700. For instance, the reservoir 704 may be fluidly coupled to the second receptacle 272 (e.g., via another branch segment extending from the reservoir 704 to the second receptacle 272). Additionally or alternatively, the reservoir 704 may be directly fluidly coupled to the fifth channel 702. By way of example, a conduit 706 may extend from the reservoir 704 to the fifth channel 702. The conduit 706 includes an inlet 708 fluidly coupled to the reservoir 704 and an outlet 710 fluidly coupled to the fifth channel 702. Thus, liquid may flow from the reservoir 704, into the inlet 708, through the conduit 706, and to the fifth channel 702 via the outlet 710, thereby bypassing flow through the second receptacle 272.
The first portion 256 and the second portion 258 may be manually movable relative to one another. For instance, a user may apply a sufficient amount of force to rotate the first portion 256 and the second portion 258 relative to one another about the hinge 750. Relative movement between the first portion 256 and the second portion 258 to transition the toy playset 250 away from the first configuration 252 disengages the first base track 262 of the first portion 256 from the second base track 264 of the second portion 258. For example, the second portion 258 includes inserts 752 extending adjacent to part of the second base track 264. The inserts 752 are configured to extend into corresponding recesses of the first portion 256 (e.g., positioned adjacent to a part of the first base track 262) in the first configuration 252. Movement of the first portion 256 and the second portion 258 relative to one another pulls the inserts 752 out of the recesses to disengage the first base track 262 from the second base track 264.
The first portion 256 also includes a cam 810, which is connected to a hook 812 extending away from the support 402. The cam 810 is movable relative to the support 402, and movement of the cam 810 relative to the support 402 drives corresponding movement of the hook 812 relative to the support 402. Furthermore, the adjustable component 274, which extends away from the support 402 in the illustrated embodiment, includes an opening 814. While the cam 810 is disengaged from the second portion 258 (e.g., while the toy playset 250 is not in the second configuration 850) to extend away from and/or out of the support 402, such as via a force imparted onto the cam 810 by a biasing member, the hook 812 is positioned such that movement (e.g., rotation) of the adjustable component 274 toward the support 402 inserts the hook 812 into the opening 814 without causing the hook 812 to engage with the adjustable component 274. As such, the hook 812 does not hinder movement of the adjustable component 274 relative to the support 402, and the adjustable component 274 may therefore move freely toward and away from the support 402.
The first portion 256 and the second portion 258 are also fluidly coupled to one another in the second configuration 850. In particular, positioning the extension 700 in the recess 800 fluidly couples the fifth channel 702 of the second portion 258 to the first receptacle 270 of the first portion 256. Consequently, the second receptacle 272 and the third channel 650 of the second portion 258 will be fluidly coupled to the first receptacle 270 of the first portion 256 (e.g., via fifth channel 702). For this reason, liquid may flow from the second portion 258 (e.g., from the third channel 650, from the second receptacle 272, from the fifth channel 702, from the reservoir 704) into the first receptacle 270, and then from the first receptacle 270, into the second channel 606, and off the toy playset 250 via the outlet 604. Additionally, liquid may flow from the first portion 256 (e.g., from the first channel 600, from the second channel 606, from the first receptacle 270) off the toy playset 250 via the outlet 604. Accordingly, liquid may flow from each of the first portion 256 and the second portion 258 toward a common outlet 604 in the second configuration 850, thereby enabling controlled flow of liquid to a common location (e.g., to facilitate cleaning of liquid from the toy playset 250).
In some embodiments, the first portion 256 includes a barrier 854 positioned in the fifth channel 702. The barrier 854 may further help direct liquid from the second portion 258 toward the outlet 604. By way of example, the barrier 854 may be positioned to block at least a portion of liquid flow from the fifth channel 702 to a part of the first receptacle 270, thereby guiding at least a portion of liquid flow toward the second channel 606 and the outlet 604. As such, the barrier 854 may encourage liquid flow off the toy playset 250 via the outlet 604. However, in some embodiments, the barrier 854 may allow limited flow into the first receptacle 270, e.g., via small openings that meter flow and/or when flow is sufficient to flow over the barrier 854. In other words, barrier 854 may act as a dam, limiting the flow of liquid into the first receptacle 270 except under certain conditions.
Further, in the second configuration 850, the second portion 258 (e.g., a cam surface 856 of the second portion 258) is engaged with the cam 810 of the first portion 256. Engagement of the second portion 258 with the cam 810 moves the cam 810 toward or into the support 402 and causes corresponding movement of the hook 812 relative to the support 402. Consequently, the hook 812 is at a different position in the second configuration 850 than in the first configuration 252 of the toy playset 250. The position of the hook 812 in the second configuration 850 may cause the hook 812 to engage with a segment 858 of the adjustable component 274 (e.g., when the adjustable component 274 extends along the support 402). The engagement of the hook 812 with the segment 858 blocks movement of the adjustable component 274 relative to the support 402. For example, the second configuration 850 may be used to transport (e.g., carry) the toy playset 250, and blocking movement of the adjustable component 274 relative to the support 402 may facilitate transportation of the toy playset 250, such as by using the handle 278 of the adjustable component 274 to lift the adjustable component 274 and the base 254 (e.g., without causing the adjustable component 274 to move relative to the first portion 256).
While the toy playsets presented herein have been illustrated and described in detail and with reference to specific embodiments thereof, it is nevertheless not intended to be limited to the details shown, since it will be apparent that various modifications and structural changes may be made therein without departing from the scope of the disclosure and within the scope and range of equivalents of the claims.
