This document relates to bed systems, and more particularly to techniques for assembling mattresses and beds.
In general, a bed is a piece of furniture used as a location to sleep or relax. Many modern beds include a soft mattress on a bed frame. The mattress may include springs, foam material, and/or an air chamber to support the weight of one or more occupants. Various features and systems have been used in conjunction with beds, including heating and cooling systems for heating and cooling a user of a bed. An increasing number of components in the bed may warrant a mechanism for assembling all the components in reliable, secured, and efficient ways.
Some embodiments described herein include a bed system with microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control system configured to supply conditioned air (e.g., heated or cooled air) to a mattress to achieve a desired temperature at a top of the mattress. Reinforcement straps can be used to hold various components of the microclimate control system within the mattress. For example, the mattress may include one or more mattress cores, airflow pads, and a rail structure. One or more airflow pads may be arranged under a mattress top and above a mattress bottom and configured to distribute conditioned air supplied from a thermal module toward the top of the mattress or draw ambient air from the top of the mattress. The rail structure defines an interior of the mattress configured to receive the mattress cores and the airflow pads. The reinforcement straps extend from the rail structure under the mattress bottom to thereby hold the mattress cores and the airflow pads within the interior defined by the rail structure between the mattress top and the mattress bottom.
According to implementations of the present disclosure, the reinforcement straps are designed to be attached to and extend between the rail structure and the mattress bottom. For example, one end of the reinforcement strap may be attached to the rail structure and the other end of the reinforcement strap may be attached to the mattress bottom. As such, the reinforcement straps may be shorter in length than the distance between the opposite sides of the rail structure to which the reinforcement straps are attached to. Therefore, each of the reinforcement straps may not extend all the way across the mattress bottom between the opposite sides of the rail structure.
In some examples, one or more (e.g., two) first reinforcement straps are attached to one of the opposite sides of the rail structure and also attached to the mattress bottom to thereby extend therebetween. Similarly, one or more (e.g., two) second reinforcement straps are attached to the other side of the rail structure and also attached to the mattress bottom to thereby extend therebetween. The position at the mattress bottom to which the first reinforcement straps are attached may be spaced apart from the position at the mattress bottom to which the second reinforcement straps are attached. In some implementations, the first reinforcement straps are arranged symmetrically to the second reinforcement straps.

The devices, systems, and techniques described herein may provide one or more of the following advantages. Some embodiments described herein include reinforcement straps that are used with a bed to secure a mattress cover to other components of the mattress system, such as the top layer, the intermediate layer, the rail structure, the mattress core.
The straps can improve the structural stability of the bed. For example, in some cases, bed components such as inflatable chambers can expand and contact the rail structure, causing the rail structure to change shape or bow. When the straps are couple to the rail structure and mattress bottom, the change in shape or bowing of the rail structure can be reduced. For example, when a person sits or lays down on the mattress, the mattress core can compress and contact the rail structure, causing the rail structure to change shape or bow. When the straps are couple to the rail structure and mattress bottom, the change in shape or bowing of the rail structure can be reduced.
The straps can decrease relative motion between mattress components. For example, when a person sits or climbs on the bed, a force can be imparted onto one or more mattress components, but not other components causing bed components to move relative to mattress components. Using straps can reduce the relative motion between mattress components.
Utilizing the straps can decrease assembly time. For example, a shorter strap can be positioned from each side of the mattress without having to flip the mattress.
The straps can decrease the personnel required to assemble the mattress. For example, each shorter strap can be positioned individually without lifting or flipping the entire mattress.
With the short reinforcement straps, which do not extend all the way across the opposite sides (e.g., left and right sides) of the mattress, the mattress can be manufactured in a time efficient and cost-efficient manner. For example, at a manufacturing site (e.g., at an assembly line), a single person can grab one or more separate short straps at each side of a partially assembled mattress and attach the straps between each side of the mattress and the mattress bottom. Alternatively, two persons positioning at the opposing sides of the mattress can attach the short straps at the opposite sides of the mattress independently. This increases efficiency in attaching the straps to the mattress, compared to longer straps that are configured to be routed all the way across the opposite sides of the mattress. Further, the straps can be used for different sizes of mattresses (e.g., king, queen, twin, etc.). Therefore, the straps can be made in a single length without considering different sizes of mattresses.
The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features and advantages will be apparent from the description and drawings, and from the claims.
The bed 102 has a head 108 and a foot 124. The head 108 can also be referred to as a head end or head-side and the foot 124 can also be referred to as a foot end or a foot-side. The bed 102 can include a mattress 104 and a foundation 106. In some embodiments, the mattress 104 can be an air mattress having an inflatable air chamber and a controller for controlling inflation of the inflatable air chamber. In other embodiments, the mattress 104 does not include an air chamber. For example, the mattress 104 may include foam and/or springs instead of or in addition to an inflatable air chamber. The mattress 104 can be sized and shaped as a twin mattress, full mattress, queen mattress, king mattress, California king mattress, split king mattresses, partially split mattress (e.g. a mattress 104 that is split at the head 108 and/or foot 124 ends and joined in a middle 126 of the mattress 104), and/or other mattress 104 as suitable for the application. The foundation 106 is positioned under the mattress 104 to support the mattress 104. In some embodiments, the foundation 106 can be an adjustable foundation with one or more articulable sections, such as for raising the head 108 and foot 124 of the foundation 106 and the mattress 104. In other embodiments, the foundation 106 can be a stationary foundation.
The bed 102 can be configured to provide a microclimate control of the mattress 104. In some implementations, the bed 102 provides a foot warming function. For example, the bed 102 can include a foot warming device 120 which is disposed on the mattress 104 or incorporated in the mattress 104 and at a foot side of the bed 102. The foot warming device 120 can be disposed on a top of the mattress 104, included in the mattress 104, or disposed at other locations of the bed 102 and/or in other configurations. The foot warming device 120 can include an electronic heating element in some implementations. The foot warming device 120 can include an air circulation element through which heated air is circulated in other implementations. Other configurations are also possible.
Alternatively or in addition, the bed 102 can be configured to provide a body cooling/heating function. For example, the bed 102 can include an airflow insert pad 122 that can be included in the mattress 104 and configured to circulate ambient or conditioned air through the mattress under the user at rest. The airflow insert pad 122 can be arranged at various locations in the mattress 104. In the illustrated example, the airflow insert pad 122 is disposed between the head 108 and foot 124 of the mattress 104 (e.g., in the middle 126 of the mattress 104).
The bed control system 110 operates to control features available for the bed 102. In some implementations, the bed control system 110 includes a bed articulation system 112, an air chamber control system 114, a foot warming control system 116, and an airflow insert pad control system 118.
The bed articulation system 112 operates to articulate the foundation 106 and/or the mattress 104. For example, the bed articulation system 112 can adjust one or more articulable sections of the foundation 106 to raise the head 108 and foot 124 of the foundation 106 and/or the mattress 104. The bed articulation system 112 can include a controller and an actuator (e.g., a motor) operated by the controller and coupled to the articulable sections of the foundation 106 so that the sections of the foundation 106 are automatically adjusted to desired positions. Alternatively or in addition, the articulable sections of the foundation 106 can be manually adjusted.
The air chamber control system 114 operates to control the air chamber of the mattress 104. The air chamber control system 114 can include a controller and an actuator (e.g., a pump) operated by the controller and fluidly connected to the air chamber. The actuator is controlled to inflate or deflate the air chamber to provide and maintain a desired pressure in the air chamber, thereby providing a desired firmness of the air chamber.
The foot warming control system 116 operates to control the foot warming device 120 disposed in the mattress 104. The foot warming control system 116 can include a controller configured to activate a heating element of the foot warming device 120 and maintain a desired temperature of the heating element.
The airflow insert pad control system 118 operates to control the airflow insert pad 122 disposed in the mattress 104. The airflow insert pad control system 118 can include an air controller configured to cause ambient or conditioned air to flow into or out of the airflow insert pad 122 so that a top layer of the mattress above or adjacent the airflow insert pad 122 have a desired temperature and/or humidity.
In some implementations, the bed articulation system 112, the air chamber control system 114, the foot warming control system 116, and the airflow insert pad control system 118 can be independently configured and operated. In other implementations, some or all of the bed articulation system 112, the air chamber control system 114, the foot warming control system 116, and the airflow insert pad control system 118 are at least partially combined so that they share at least part of their components such as actuators (e.g., motors, pumps, etc.) and/or controllers (e.g., control circuits, processors, memory, network interfaces, etc.).
The bed control system 110 can be accessed by a user via one or more control devices 130, such as a bed-side controller 132 and a mobile computing device 134. The bed-side controller 132 is wired to, or wirelessly connected to, the bed control system 110 to enable the user to at least partially control the bed control system 110. The bed-side controller 132 includes an input device (e.g., a keypad, buttons, switches, etc.) for receiving a user input of controlling various settings of the bed control system 110, such as articulation positions, temperature settings, air chamber pressure settings, etc. The bed-side controller 132 can further include an output device (e.g., a display, a speaker, etc.) for outputting the statuses and conditions of the bed control system 110 and other information useful to the user, such as articulation positions, temperature settings, air chamber pressure settings, sleep analysis results, etc. The same or similar functionalities can be implemented with the mobile computing device 134, such as a mobile device running a dedicated software application. For example, the user can use a mobile device as an input device to control various settings of the bed control system 110, such as articulation positions, temperature settings, air chamber pressure settings, etc., and further use the mobile device as an output device to see the statuses and conditions of the bed control system 110 and other useful information, such as articulation positions, temperature settings, air chamber pressure settings, sleep analysis results, etc.

In some implementations, the server system 140 can provide a bed data service that can be used in a data processing system associated with the local bed system 101. The server system 140 can be configured to collect sensor data and sleep data from a particular bed and match the sensor and sleep data with one or more users that use the bed when the sensor and sleep data were generated. The sensor and sleep data, and the matching data, can be stored as bed data 150 in a database. The bed data 150 can include user identification data usable to identify users of beds. The users can include customers, owners, or other users registered with the server system 140 or another service. Each user can have, for example, a unique identifier, user credentials, contact information, billing information, demographic information, or any other technologically appropriate information. The bed data 150 can include management data usable to identify data related to beds or other products associated with data processing systems. For example, the beds can include products sold or registered with a system associated with the server system 140. Each bed can have, for example, a unique identifier, model and/or serial number, sales information, geographic information, delivery information, a listing of associated sensors and control peripherals, etc. Additionally, an index or indexes stored in the bed data 150 can identify users that are associated with beds. For example, this index can record sales of a bed to a user, users that sleep in a bed, etc. The bed data 150 can include sensor data that record raw or condensed sensor data recorded by beds with associated data processing systems. For example, a bed's data processing system can have a temperature sensor, pressure sensor, and light sensor. Readings from these sensors, either in raw form or in a format generated from the raw data (e.g., sleep metrics) of the sensors, can be communicated by the bed's data processing system to the server system 140 for storage in the bed data 150. Additionally, an index or indexes stored by the server system 140 can identify users and/or beds that are associated with the sensor data. In some implementations, the server system 140 can use any of its available data to generate advanced sleep data. The advanced sleep data includes sleep metrics and other data generated from sensor readings. Some of these calculations can be performed in the server system 140 instead of locally on the bed's data processing system, for example, because the calculations are computationally complex or require a large amount of memory space or processor power that is not available on the bed's data processing system. This can help allow a bed system to operate with a relatively simple controller and still be part of a system that performs relatively complex tasks and computations.
Alternatively or in addition, the server system 140 can provide a sleep data service that can be used in a data processing system that can be associated with the local bed system 101. In this example, the server system 140 is configured to record data related to users' sleep experience and store the data as sleep data 152. The sleep data 152 can include pressure sensor data related to the configuration and operation of pressure sensors in beds. For example, the pressure sensor data can include an identifier of the types of sensors in a particular bed, their settings and calibration data, etc. The sleep data 152 can include pressure-based sleep data which can be calculated based on raw pressure sensor data and represent sleep metrics specifically tied to the pressure sensor data. For example, user presence, movements, weight change, heart rate, and breathing rate can be determined from raw pressure sensor data. Additionally, an index or indexes stored by the server system 140 can identify users that are associated with pressure sensors, raw pressure sensor data, and/or pressure-based sleep data. The sleep data 152 can include non-pressure sleep data which can be calculated based on other sources of data and represent sleep metrics obtained from such other sources of data. For example, user entered preferences, light sensor readings, and sound sensor readings can all be used to track sleep data 152. Additionally, an index or indexes stored by the server system 140 can identify users that are associated with other sensors and/or non-pressure sleep data 152.
Alternatively or in addition, the server system 140 can provide a user account service that can be used in a data processing system associated with the local bed system 101. For example, the server system 140 can record a list of users and to identify other data related to those users and store such data as user account data 154. The user account data 154 are related to users of beds with associated data processing systems. For example, the users can include customers, owners, or other users registered with the server system 140 or another service. Each user can have, for example, a unique identifier, user credentials, demographic information, or any other technologically appropriate information. The user account data 154 can include engagement data usable to track user interactions with the manufacturer, vendor, and/or manager of the bed and/or cloud services. This engagement data can include communications (e.g., emails, service calls), data from sales (e.g., sales receipts, configuration logs), and social network interactions. The user account data 154 can include usage history data related to user interactions with one or more applications and/or remote controls of a bed. For example, a monitoring and configuration application can be distributed to run on, for example, the control devices 130. This application can log and report user interactions for storage. Additionally, an index or indexes stored by the server system 140 can identify users that are associated with each log entry.
Alternatively or in addition, the server system 140 can provide an environment service that can be used in a data processing system associated with the local bed system 101. For example, the server system 140 can record data related to users' home environment and store such data as environment data 156. The environment data 156 can be obtained using one or more sensors installed in or around the bed. Such sensors can be of various types that can detect environmental variables, such as light sensors, noise sensors, vibration sensors, thermostats, etc. The environment data 156 can include historical readings or reports from those sensors. By way of example, a light sensor is used to collect data indicative of the frequency and duration of instances of increased lighting when the user is asleep.

The mattress system 200 further includes an airflow layer 230 configured to distribute ambient or conditioned air therethrough and into the top layer 202, and/or draw ambient or conditioned air therethrough and from the top layer 202. The airflow layer 230 can include one or more airflow pad assemblies 232. An example of the airflow pad assembly 232 is described in more detail herein, for example with reference to
As depicted in
The top layer 202, the intermediate layer 204, the rail structure 206, and the bottom layer 208 can be made of various materials. For example, at least one of the top layer 202, the intermediate layer 204, the rail structure 206, and the bottom layer 208 can be made of foam, which may be closed-cell, open-cell, or a combination thereof. Other materials, such as one or more coil springs, air chambers, spacer materials, and/or other suitable materials, can be used for at least one of the top layer 202, the intermediate layer 204, the rail structure 206, and the bottom layer 208.
The intermediate layer 204 can be disposed opposite to the top surface 212 of the top layer 202. For example, the top layer 202 has the bottom surface 214 opposite to the top surface 212, and the intermediate layer 204 is disposed on the bottom surface 214 of the top layer 202. The second layer 204 (the intermediate layer or additionally the bottom layer 208) has a second layer top 238 and a second layer bottom 244. The second layer bottom 244 is opposite the second layer top 238. The second layer 204 extends between a first side rail 566 and a second side rail 568 (described in more detail in reference to
In some implementations, the intermediate layer 204 provides a cutout section 240 configured to receive the airflow layer 230. The cutout section 240 is described in further detail with reference to
In alternative embodiments, the mattress system 200 does not include the top layer 202. In this configuration, the bottom layer 208 can function as a top layer of the mattress. Alternatively, the top layer 202 can have different sizes (e.g., thickness) to provide different comfort levels or for other purposes.
In some implementations, the intermediate layer 204 can be arranged in parallel to the airflow layer 230 (e.g., air distribution layer). For example, the intermediate layer 204 can be configured to be parallel with the airflow pad assemblies 232 when assembled.

As described, the mattress 200 includes the inflatable air chamber 222, the airflow layer 230 (e.g., an air distribution layer), and a foam layer 203. The foam layer 203 can include the top layer 202. The foam layer 203 can further include the intermediate layer 204. The air distribution layer is positioned above the inflatable air chamber 222. The foam layer 203 is positioned above the air distribution layer and proximate a top of the mattress. As described herein, the foam layer 203 and the air distribution layer (e.g., the airflow layer 230) can permit airflow therethrough. The air distribution layer resists air flow less than the foam layer. For example, the air distribution layer can allow a higher airflow rate than the foam layer above the air distribution layer. The mattress 200 further includes a first air chamber hose 226A and a second air chamber hose 226B (shown in
In some implementations, the mattress 200 includes the mattress cover 209 that at least partially encloses the components of the mattress 200, such as the top layer 202, the intermediate layer 204, the rail structure 206, the air chamber 222, the airflow layer 230, and the bottom layer 208. The mattress cover 209 includes a common hole 211 through which the air distribution hose and the air chamber hose can extend out together.
In some implementations, the mattress 200 includes a plurality of inflatable air chambers, and the air distribution layer includes a plurality of air distribution zones or pads corresponding to the plurality of inflatable air chambers. In the illustrated examples, the mattress 200 includes first and second air chambers 222A and 222B, and the air distribution layer includes two air distribution pads 232A and 232B (defining two air distribution zones) that are positioned under the first and second air chambers 222A and 222B, respectively, from the view of
In some implementations, the mattress 200 includes a chamber insulator 250 positioned between the first and second air chambers 222A and 222B and configured to reduce heat transfer between the first and second air chambers 222A and 222B. In addition or alternatively, the mattress 200 includes an air distribution insulator 260 positioned between the first and second air distribution pads 232A and 232B and configured to reduce heat transfer between the first and second air distribution pads 232A and 232B. The chamber insulator 250 and the air distribution insulator 260 can reduce heat transfer between two different areas (e.g., left and right sides) of the mattress 200, thereby improving independent temperature controls for different users resting on such different areas of the mattress top.
As shown in
In some implementations, a foundation (e.g., the foundation 106) can be provided to support the mattress 200. For example, the foundation provides a support platform configured for supporting the mattress 200. The support platform can include a first foundation opening extending through the support platform and configured to receive the air chamber hose and/or the air distribution hose. A pump assembly (e.g., the pump assembly 224 as shown in

Similar to the airflow layer 230 described herein, the airflow layer 330 can include an airflow pad assembly 332. The airflow pad assembly 332 can include one or more airflow pads 334 and an air duct 336 extending from the airflow pad 334 and fluidly connecting the airflow pad 334 with an air controller 338. The air controller 338 is configured to move ambient or conditioned air through the airflow pad 334 and further through the top layer 302 to control a temperature at a top surface 312 of the top layer 302. For example, the air controller 338 can operate to draw air from the airflow pad 334 and the top layer 302 through the air duct 336, thereby decreasing a temperature at the top surface 312 of the top layer 302. Alternatively, the air controller 338 can operate to supply ambient or cooling air to the airflow pad 334 through the air duct 336, thereby enabling such ambient or cooling air to be distributed through the top layer 302 and decreasing a temperature at the top surface 312 of the top layer 302. Alternatively, the air controller 338 can operate to supply heating air to the airflow pad 334 through the air duct 336, thereby enabling such heating air to be distributed through the top layer 302 and increasing a temperature at the top surface 312 of the top layer 302.
In the illustrated implementations, the air chamber hoses 226A, 226B are routed at the side locations of the mattress. In alternative implementations, the air chamber hoses 226A, 226B can be routed at different locations of the mattress, such as the head 108 or foot 124 of the mattress 104, or other suitable locations of the mattress 104.
In the illustrated implementations, the air ducts 234 are positioned at the side locations of the mattress 104. In alternative implementations, the air ducts 234 can be routed at other locations of the mattress 104. For example, at least one of the air ducts 234 can be arranged in the middle 126 of the mattress 104 and travel between the air chambers 222 of the mattress 104.

Similar to the airflow pad assembly 232, 332, the airflow pad assembly 400 includes an airflow pad 402 and an air duct 404. The airflow pad 402 is arranged under a top layer of a mattress system, such as the top layer 202, 302 of the mattress system 200, 300. The airflow pad 402 is configured to permit air to flow therethrough and further through the top layer above the airflow pad 402. In this example, the top layer of the mattress system can be made of foam, which may be closed-cell, open-cell, or a combination thereof, so that air can be distributed through the top layer. In some implementations, the airflow pad 402 is configured to permit an airflow rate that is higher than an airflow rate of the top layer above the airflow pad 402.
The airflow pad 402 can permit ambient or conditioned air to flow therethrough and further through the top layer above the airflow pad 402 to control a temperature at a top surface (e.g., a surface opposite to the airflow pad 402) of the top layer. In some implementations, air can be drawn from the airflow pad 402 and thus from the top layer above the airflow pad 402, thereby decreasing a temperature at the top surface of the top layer above the airflow pad 402. For example, when a user rests on the top surface of the top layer in the mattress system, drawing air from the airflow pad 402 causes air to be further drawn from the top layer, and thus cools both the top layer and the user's body contacting the top layer. In other implementations, ambient or cooling air can be supplied to the airflow pad 402 and thus distributed through the top layer above the airflow pad 402, thereby decreasing a temperature at the top surface of the top layer above the airflow pad 402. In a similar example where a user rests on the top surface of the top layer in the mattress system, supplying ambient or cooling air to the airflow pad 402 causes air to be further distributed into and throughout the top layer, and thus cools the user's body contacting the top layer. In yet other implementations, heating air can be supplied to the airflow pad 402 and thus distributed through the top layer above the airflow pad 402, thereby increasing a temperature at the top surface of the top layer above the airflow pad 402. In a similar example where a user rests on the top surface of the top layer in the mattress system, supplying heating air to the airflow pad 402 causes air to be further distributed into and throughout the top layer, and thus warms the user's body contacting the top layer.

In some implementations, the airflow material 410 can have three-dimensional structures with elastic polyolefin fibers. Alternatively or in addition, the airflow material 410 is made of 100% polyolefin. Alternatively or in addition, the airflow material 410 is configured to provide a resilience rate of thickness no less than 95% after 80,000 times of repeated compressions. In addition or alternatively, the airflow material 410 includes Qshion™ material, which is available from Qshion 4D, Taiwan, R.O.C. The Qshion™ material provides complex three-dimensional structures with elastic polyolefin fibers which provide desired ventilation and sleeping environment. Further, the Qshion™ material includes a breathable, non-toxic, recyclable POE material which can provide full support and comfort. The Qshion™ material is washable and dries quickly. The Qshion™ material allows airflow to keep a user cool and comfortable for an extended period of time (e.g., overnight). Further, the Qshion™ material is configured to help relieve joint and muscle pressure of a user. The Qshion™ material is a nontoxic, recyclable material which allows a user to sleep in a safe and healthy environment. The Qshion™ material is more breathable than foam materials. Further, the Qshion™ material has a resilience rate of thickness no less than 95% after 80,000 times of repeated compressions, while foam materials typically have resilience rates of thickness of 90% or less after the same repeated compressions. The Qshion™ material does not absorb moisture and free of dust mites, while foam materials keep humidity and lead to mold. In other embodiments, the airflow material 410 can be different than Qshion™ material in some ways and yet include one, more than one, or all of the above-identified properties of Qshion™ material.
In some implementations, the airflow material 410 may have one or more of an anti-microbial property or an anti-fungal property. For example, the airflow material 410 can include silver or copper.
The pad cover 412 is configured to cover the airflow material 410. For example, the pad cover 412 is configured to at least partially enclose the airflow material 410. In some implementations, the pad cover 412 can include a zip fastener 414 (
As illustrated in
In some implementations, the edges of the vent 416 can be spaced inward of the perimeter of the airflow pad 402 to form a border around the vent 416. The border around the vent 416 can ensure that the surface (e.g., the top surface) of the airflow pad 402 is not entirely the vent 416. For example, the vent 416 is sized to have edges spaced at widths D1-D4 from the perimeter of the pad cover 412. The widths D1-D4 can be determined such that the border around the vent 416 is wider on the side so as to have less or no flow near the outer side of the airflow pad 402, and more flow in the middle and near the inner side of the airflow pad 402. In some implementations, the inlet/outlet (e.g., the pad-side end 430) of the air duct 404 are arranged in a portion of the airflow pad 402 that corresponds with (e.g., aligned with) the border around the vent 416. For example, the pad-side end 430 of the air duct 404 is arranged opposite side of a border (the portion having the width D3) of the airflow pad 402. Such arrangement of the inlet/outlet of the air duct 404 can prevent airflow from just blasting upwards from the air duct 404 directly through the vent 416 in an air supply mode, or from suctioning downwards into the air inlet/outlet of the air duct 404 directly through the vent 416 in an air draw mode. Rather, the arrangement of the inlet/outlet of the air duct 404 can allow air to evenly distributed through the entire airflow material 410 (or a majority thereof) as it flows between the inlet/outlet of the air duct 404 and the vent 416.
The pad cover 412 can be configured to provide a plenum chamber that substantially surround a core of the airflow material 410. For example, the pad cover 412 is made of a material that limits airflow while permitting for air to flow through the vent 416. As illustrated, the airflow material 410 can be configured as a layer generally having a top, a bottom, and sides. The pad cover 412 is positioned on at least part of the top, the bottom, and the sides of the airflow material 410, and provides an opening through the vent 416 arranged on the pad cover 412 abutted with the top of the airflow material 410. The vent 416 can be covered by a meshed material or other materials that permit airflow, so that air can flow through the vent 416 and out of or into the airflow material 410 surrounded by the pad cover 412.
The airflow pad 402 is fluidly connected to the air duct 404 at one end. The other end of the air duct 404 can be fluidly connected to an air controller (e.g., the air controller 338) configured to supply ambient or conditioned air into the airflow pad 402 through the air duct 404 and/or draw air from the airflow pad 402 through the air duct 404.
Referring to
As described herein, the airflow pad 402 can be configured to include various features that permit for the airflow pad 402 to have a small form factor. For example, the airflow material 410 and the pad cover 412 are configured to provide a smaller thickness of the airflow pad 402 than a layer (e.g., the top layer 202) above the airflow pad 402. For example, the intermediate layer 204 that incorporates the airflow pad assembly 400 (including one or more airflow pads 402) can be configured to have a smaller thickness than the top layer 202 so that the comfort that the top layer 202 can provide is not reduced or otherwise compromised by the inclusion of the intermediate layer 204 and/or the airflow pad assembly 400 (including the airflow pads 402). In some implementations, a ratio in thickness of the top layer 202 over the intermediate layer 204 can range between about 1.2 to about 10. By way of example, the top layer 202 can be made to be 4 inches thick while the intermediate layer 204 (including the airflow pad assembly 400) can be made to be 1 inch thick. As may be appreciated, however, any suitable ratio in thickness may be used.

The reinforcement straps 550A-550D can be a fabric such as cotton, polyester, canvas, vinyl, tweed, suede, or corduroy. In some cases, the fabric is semi-rigid. In other cases, the fabric has minimal stretch. In some implementations, the fabric is a blend of inherent flame-retardant rayon, polyester, and para-aramid. For example, the fabric can be 50% flame retardant rayon, 45% polyester, and 5% para-aramid. Any suitable material or combination of materials may be used.

The rail structure 506 can include a head rail 562, a foot rail 564, and first side rail 566 and second side rail 568 extending between the head rail 562 and the foot rail 564 opposite the first side rail 566. The first side rail 566 is attached to the bottom 214 of the top layer 202 proximate to the first layer edge 228. The second side rail 568 is attached to the bottom 214 of the top layer 202 proximate to the second layer edge 236.
In some implementations, the rail structure 506 can be made of one or more foam materials. In this example, the rail structure 506 is attached to the intermediate layer 504. When attached to the intermediate layer 504, the rail structure 506 may be also engaged with, or attached to, the airflow layer 530 that is positioned in a cutout section of the intermediate layer 504 (e.g., to be flushed with the intermediate layer 504). For example, the head rail 562 is attached to a bottom of the intermediate layer 504 at (or proximate) a head edge of the intermediate layer 504, and the foot rail 565 is attached to the bottom of the intermediate layer 504 at (or proximate) a foot edge of the intermediate layer 504 (opposite to the head edge of the intermediate layer 504). The first and second side rails 566, 568 are attached to the bottom of the intermediate layer 504 at (or proximate) opposite sides of the intermediate layer 504. Similar to the rail structure 206, 306, the rail structure 506 forms an upside-down foam tub, along with the layers (e.g., the intermediate layer 504, the airflow layer 530, and/or the top layer 502). For example, the rail structure 506 defines a space for receiving a mattress core, such as one or more inflatable air chambers (e.g., the air chambers 222 in

Similarly, the second first-side strap 550B can be connected to the first side rail 566 and extend under the core or the bottom surface 516 of the bottom layer 208 from the first side rail 566 to bottom surface 516. One end 508B of the second first-side strap 550B can be connected to a third connection location 570B located on the bottom 510 of the first side rail 566, and another end 512B of the second first-side strap 550B can be connected to a fourth connection location 514B located on the bottom surface 516 of the bottom layer 208.

For example, the first first-side strap 550A is arranged close to the second first-side strap 550B and extends to be parallel with the second first-side strap 550B. The first first-side strap 550A can be arranged at a distance 522 from the second first-side strap 550B. An example of the distance 522 can range from about 5 inches to about 70 inches.

The reinforcement straps 550A-550D have a width 536. For example, the widths 536 of the reinforcement straps 550A-550D can be between 0.5 inches and 115 inches. The widths 536 of each of the first first-side strap 550A, the second first-side strap 550B, first second-side strap 550C, the second second-side strap 550D can be the same or differ. The reinforcement straps 550 extend along the first and second side rails 566, 568 for the respective width 536 to attach to the bottom layer 208. For example, the shortest width 536 that the reinforcement straps 500 can each extend along first and second side rails 566, 568 for 0.5 inches. For example, the reinforcement straps 550 can extend along the first and second side rails 566, 568 for a distance of 115 inches, that is, the width 536 is 115 inches. In some cases, the reinforcement straps 550 can extend along the first and second side rails 566, 568 from the top rail to the bottom rail. In some cases, the first first-side strap 550A and the second first-side strap 550B can each have the width 536 of 57.5 inches for a total of 115 inches. For example, the first first-side strap 550A and the second first-side strap 550B can each have a width 536 of 0.5 inches for a total of one inch. In some implementations, the arrangement can vary depending on the size of the notch in the foam. It can also vary depending on the size of the base pad and its location. The measurements can also depend on whether the straps are perpendicular to the rails or not, whether the straps are perpendicular to one another, etc.

In one example, the fastener elements 574 of each of the straps 550 are microhooks attached at its both ends (for example, ends 508A and 512A) and the person can simply peel off the protection films from the microhooks and attach them to the side rail 566 and the bottom layer 516. In a similar manner, one or more of the straps 550B-550D can be attached to the respective side rail 566, 568.
In an alternative example, one end 508A of the strap 550A can be permanently attached to the side rail 566 (for example, by an adhesive) and the other end 512A of the strap 550A can be detachable (for example, with the microhooks). However, any suitable attachment components or methods may be used. In some cases, this can be more beneficial because the strap 550A is integrated into the bed rail 556. In a similar manner, one or more of the straps 550B-550D can be attached to the respective side rail 566, 568.
The fastening elements 574 can be applied at the connection locations 570A-B, 572A-B, 514A-D, or at desired locations (e.g., the ends 508A-508D and 512A-512D) of the straps 550, so that such desired location of the straps 550 are attached to the connection points of the rail structure 506. For example, adhesive tapes can be applied between the connection locations 570A-B, 572A-B of the rail structure and the ends 512A-D of the straps 550. The fastening elements 574 couple the reinforcement straps 550 to the first and second side rails 566, 568 and the bottom surface 516. The ends 508A-508B of the reinforcement straps 550A-550B are coupled to the first side rail 566 and the ends 508C-508D are coupled to the second side rail 568 by fastening elements 574. The ends 512A-512D of the reinforcement straps 550A-550D terminate at different locations 514A-D, respectively on the bottom surface 516. The reinforcement straps 550A-550D are not fastened to each other but may contact or touch each other as described in reference to
As illustrated in
As such, the reinforcement straps that extend between rails and run across the bottom of the mattress can help hold the mattress core and other mattress components in place and keep them from bowing outwards after repeated edge of bed stress from a user entering and exiting. The reinforcement straps can be used with pieces of hook materials (e.g., 3M hook materials) with adhesive backing. The hook materials can be placed along the bottom side of the perimeter side rails. In some implementations, the reinforcement straps can include a scrim material and attach to the hook materials and extend from one side of the bed to the other side. The straps are removable to allow other components (e.g., the air chambers, layers, etc.) to be assembled without interference. The straps can be adjustable to accommodate for stretch or changes over time, varying tolerances of the foam tub and its cover, or general aesthetic preference impact. The straps can have a width of varying sizes, such as a width ranging between about 0.5 inches and about 115 inches.
In some embodiments, the straps 550A-550B can each extend from one side rail 566, across the longitudinal middle section 518, to the second side rail 568 and the straps 550C-550D can each extend from the other side rail 568, across the longitudinal middle section 518, to the first side rail 566. This can use relatively long straps 550A-550D that extend across all or most of the mattress 500. According to implementations of the present disclosure, the straps 550A-550B and 550C-550D can be shorter than other types of straps that extend across all or most of the width of the mattress 500. Again, the shorter straps 550A-D extend from each of the first side rail 566 and the second side rail 568, respectively, across the longitudinal middle section 518, toward the other rail, respectively, without extending across the entire mattress 500. As described above, the mattress 500 with shorter straps 550A-550D can have a number of advantages over systems of longer straps 550A-550D. For example, some systems with shorter straps 550A-550D can be easier to use because a user or person installing the straps (the installer) can reach both ends 508A, 512A of the strap 550A from a single side of the mattress 500. Additionally, some mattress 500 with shorter straps 550A-550D can use less strap material, and therefore, be less expensive and lower weight. Moreover, in those embodiments where the straps 550 are angled in a manner as described in reference to
As illustrated in
In this example, the bottom layer 1702 includes reinforcement straps 1704a-d coupled to the bottom layer. The reinforcement straps 1704a-d each have a first end 1706a-d, respectively, coupled to the bottom layer 1702. The reinforcement straps 1704a-d each have a second end 1708a-d, respectively, extending from the bottom layer 1702. As illustrated, the first end 1706a-d is an end fixed to the bottom layer 1702, and the second end 1708a-d is a first end which may be free to be detached and reattached to the rail structure.
In some cases, as shown in
The reinforcement straps 1704a-d have fastening elements 574 to couple the second ends 1708a-d to the side rails 566, 568. The same or similar fastening elements described with reference to
The bottom layer 1702 can include recessed portions 1712 where the reinforcement straps 1704a-d extend. For example, the bottom layer 1702 has head and foot edges 1714 and 1716 and opposite side edges 1718, 1720 extending between the head and foot edges 1714 and 1716. The side edges 1718,1720 can be curved toward an inner portion 1722 of the bottom layer 1702. In some implementations, the side edges 1718,1720 can be curved away from the first and second side rails 566 and 568 when the bottom layer 1702 is attached to the rail structure 206. Therefore, when the bottom layer 1702 is attached to the rail structure 206, the curved side edges 178, 1720 and the respective first and second side rails 566 and 568 define the recessed portions 1712 (with respect to the dotted lines in
While this specification contains many specific implementation details, these should not be construed as limitations on the scope of any inventions or of what may be claimed, but rather as descriptions of features specific to particular implementations of particular inventions. Certain features that are described in this specification in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable sub-combination. Accordingly, various features have been described above in the feature groups for clarity and organization purposes, however, it will be understood that features from the various feature groups can be beneficially combined together in a common system. Accordingly, various embodiments are specifically intended to include features of more than one, and sometimes many, feature groups. Moreover, although features may be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination may be directed to a sub-combination or variation of a sub-combination.
Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing may be advantageous. Moreover, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.
Thus, particular implementations of the subject matter have been described. Other implementations are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In certain implementations, multitasking and parallel processing may be advantageous. As used herein, the terms “approximately,” “about,” “substantially”, and similar terms are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains. It should be understood by those of skill in the art who review this disclosure that these terms are intended to allow a description of certain features described and claimed without restricting the scope of these features to the precise numerical ranges provided. Accordingly, these terms should be interpreted as indicating that insubstantial or inconsequential modifications or alterations of the subject matter described and claimed are considered to be within the scope of the invention as recited in the appended claims.
As used herein, the term “approximately” refers to a condition or parameter which can have a value or threshold value generally within acceptable engineering, machining, measurement, or manufacturing tolerances. For example, the parameter value or threshold value can be considered approximately met when the value is within 5% of the actual parameter value or threshold value. For example, the parameter value can be considered to be equal to the threshold value when the parameter value is within 5% of the threshold value. However, different approximations for different parameter values or threshold values may be used in different embodiments.
