This application claims priority to Chinese Patent Application No. 202323546953.1, filed on Dec. 26, 2023, which is hereby incorporated by reference in its entirety.
The present disclosure relates to the field of home furnishings technologies, and in particular, to an inflatable bed.
Inflatable beds are generally formed using flexible plastic sheet, which forms a sealed cavity through a top sheet, a bottom sheet, and a surrounding sheet. In order to limit an outward expansion of the inflatable bed to form a flat top and bottom surface, internal tensioning beams are disposed in the inflatable bed to connect the top sheet and the bottom sheet, which can meet basic use functions. However, when the height of the inflatable bed is high, this type of inflatable bed has disadvantages of poor stability and easy rollover, and the surrounding sheet expands outward more severely, which is unable to maintain a relatively flat appearance.
In order to solve the problems of poor stability of the inflatable bed and severe outward expansion of the surrounding sheet, some inflatable beds are equipped with four upper diagonal tensioning beams connecting the top sheet and the surrounding sheet respectively, and four lower diagonal tensioning beams connecting the bottom sheet and the surrounding sheet respectively. This renders support points at a bottom of a mattress are moved outward, improves the stability of the inflatable bed, and limits the outward expansion of the surrounding sheet, rendering the surrounding sheet of the inflatable bed have a relatively flat appearance. The drawback of this inflatable bed structure is that when the four upper diagonal tensioning beams are connected to the top sheet and the surrounding sheet, and when the four lower diagonal tensioning beams are connected to the bottom sheet and the surrounding sheet, they cannot be completed in one-go welding molds, and can only be connected one by one, which results in low processing efficiency and increased processing cost.
The purpose of the present disclosure is to provide solutions to the above-mentioned problems, as explained in the following.
To achieve the above objectives, the present disclosure provides the following technical solutions.
The present disclosure provides an inflatable bed, which includes an inflatable chamber surrounded by a top sheet, a bottom sheet, and a surrounding sheet; and a plurality of internal tensioning members that are connected to the top sheet and the bottom sheet and provided in the inflatable chamber; where the inflatable bed further includes a non-closed annular upper diagonal tensioning beam and a lower diagonal tensioning beam that are provided in the inflatable chamber; an upper end of the upper diagonal tensioning beam is connected to the top sheet and a lower end of the upper diagonal tensioning beam is connected to the surrounding sheet, thereby forming an upper edge frame; an upper end of the lower diagonal tensioning beam is connected to the surrounding sheet and a lower end of the lower diagonal tensioning beam is connected to the bottom sheet, thereby forming a lower edge frame.
In some embodiments of the present disclosure, the upper diagonal tensioning beam and the lower diagonal tensioning beam are both provided with gaps, the upper edge frame and the lower edge frame are communicated with gas in the inflatable chamber through the gaps.
In some embodiments of the present disclosure, both the upper diagonal tensioning beam and the lower diagonal tensioning beam are single sheet and in a bent circular structure.
In some embodiments of the present disclosure, the upper diagonal tensioning beam is connected to the top sheet via a first weld seam, the upper diagonal tensioning beam is connected to the surrounding sheet via a second weld seam, the lower diagonal tensioning beam is connected to the surrounding sheet via a third weld seam, and the lower diagonal tensioning beam is connected to the bottom sheet via a fourth weld seam; where the first weld seam, the second weld seam, the third weld seam, and the fourth weld seam are a non-closed circular shape.
In some embodiments of the present disclosure, the second weld seam and the third weld seam are arranged in parallel and spaced apart.
In some embodiments of the present disclosure, the internal tensioning member is an internal tensioning beam.
In some embodiments of the present disclosure, the internal tensioning beam is at least one of a straight tensioning beam, a wavy tensioning beam, and a coil tensioning beam.
In some embodiments of the present disclosure, the internal tensioning member includes a first connector, a rope-like tensioning beam, and a second connector; where the first connector is provided on an inner surface of the top sheet, the second connector is provided on an inner surface of the bottom sheet; the first connector and the second connector are connected by the rope-like tensioning beam.
In some embodiments of the present disclosure, two ends of the rope-like tensioning beam are respectively detachably connected to the first connector and the second connector.
In some embodiments of the present disclosure, the surrounding sheet is provided with an air valve or an electric air pump.
The beneficial effect is that a one-time welding forming process is used to fixedly connect the non-closed annular tensioning beam and the surrounding sheet, and during a welding process, an incomplete welding gap is formed between the non-closed annular tensioning beam and the surrounding sheet. At the gap, the non-closed annular tensioning beam and the surrounding sheet have a gap and form a channel, and a central inflatable chamber and an edge inflatable chamber are communicated through the channel. In this way, the one-time welding forming not only achieves a connection between the non-closed annular tensioning beam and the surrounding sheet, but also forms the channel connecting adjacent inflatable chambers, with a simple process and high efficiency. When inflating, taking the example of an inflation hole located in the central inflatable chamber, gas in the central inflatable chamber can enter the edge inflatable chamber through the channel, achieving simultaneous inflation of the central inflatable chamber and the edge inflatable chamber with high inflation efficiency. After inflation is completed, the non-closed circular tensioning beam plays a reinforcing role, rendering the edge of the bed body less prone to collapse, providing comfortable use and high safety. At the same time, due to an intact overall structure of the non-closed circular tensioning beam, it has strong tensile strength, is not easily damaged during use, has a long service life, and is low-cost to use.

As shown in
In an implementation mode, both the upper diagonal tensioning beam 3 and the lower diagonal tensioning beam 4 are provided with gaps, and the upper edge frame 12 and the lower edge frame 13 are communicated with gas in the inflatable chamber 7 through the gaps.
The gap of the upper diagonal tensioning beam 3 is a first gap 301; the gap of the lower diagonal tensioning beam 4 is a second gap 401.
In an implementation mode, both the upper diagonal tensioning beam 3 and the lower diagonal tensioning beam 4 are single sheet and in a bent circular structure.
In an implementation mode, the upper diagonal tensioning beam 3 is connected to the top sheet 1 via a first weld seam 8, the upper diagonal tensioning beam 3 is connected to the surrounding sheet 2 via a second weld seam 9, the lower diagonal tensioning beam 4 is connected to the surrounding sheet 2 via a third weld seam 10, and the lower diagonal tensioning beam 4 is connected to the bottom sheet 6 via a fourth weld seam 11. The first weld seam 8, the second weld seam 9, the third weld seam 10, and the fourth weld seam 11 form a non-closed circular shape that is disconnected at one point. When using the non-closed circular connection way, the upper diagonal tensioning beam 3 can be stably connected to the top sheet 1, and the lower diagonal tensioning beam 4 can be stably connected to the bottom sheet 6; using a one-time welding forming process, the non-closed annular tensioning beam is fixedly connected to the surrounding sheet 2, and during a welding process, an incomplete welding gap is formed between the non-closed annular tensioning beam and the surrounding sheet 2. At the gap, the non-closed annular tensioning beam and the surrounding sheet 2 have a gap and form a channel, and a central inflatable chamber 7 and an edge inflatable chamber 7 are communicated through the channel.
In an implementation mode, the second weld seam 9 and the third weld seam 10 are arranged in parallel and spaced apart.
In an implementation mode, the internal tensioning member 5 is an internal tensioning beam.
In an implementation mode, the internal tensioning beam is at least one of a straight tensioning beam, a wavy tensioning beam, and a coil tensioning beam. The inner tensioning beam can connect the top sheet 1 and the bottom sheet 6, thereby improving the connection stability of the inflatable bed. In an implementation mode, the tensioning beam is a flexible tensioning beam. When the inflatable bed is deflated, the tensioning beam can be folded or rolled along with the top sheet 1, the bottom sheet 6, and the surrounding sheet 2.
After inflation, it can also connect the top sheet 1 and the bottom sheet 6 stably, thereby improving the use stability of the inflatable bed.
In an implementation mode, the surrounding sheet 2 is provided with an air valve or an electric air pump.
The beneficial effect is that a one-time welding forming process is used to fixedly connect the non-closed annular tensioning beam and the surrounding sheet 2, and during a welding process, an incomplete welding gap is formed between the non-closed annular tensioning beam and the surrounding sheet 2. At the gap, the non-closed annular tensioning beam and the surrounding sheet 2 have a gap and form a channel, and the central inflatable chamber 7 and the edge inflatable chamber 7 are communicated through the channel. In this way, the one-time welding process not only achieves a connection between the non-closed annular tensioning beam and the surrounding sheet 2, but also forms the channel connecting adjacent inflatable chambers 7, with a simple process and high efficiency. When inflating, taking the example of an inflation hole located in the central inflatable chamber 7, gas in the central inflatable chamber 7 can enter the edge inflatable chamber 7 through the channel, achieving simultaneous inflation of the central inflatable chamber 7 and the edge inflatable chamber 7 with high inflation efficiency. After inflation is completed, the non-closed circular tensioning beam plays a reinforcing role, rendering the edge of the bed body less prone to collapse, providing comfortable use and high safety. At the same time, due to an intact overall structure of the non-closed loop tensioning beam, it has strong tensile strength, is not easily damaged during use, has a long service life, and is low-cost to use.
Referring to
In an implementation mode, both the upper diagonal tensioning beam 3 and the lower diagonal tensioning beam 4 are provided with gaps, and the upper edge frame 12 and the lower edge frame 13 tensioning beam 4 are communicated with gas in the inflatable chamber 7 through the gaps. The gap of the upper diagonal tensioning beam 3 is a first gap 301; the gap of the lower diagonal tensioning beam 4 is a second gap 401.
In an implementation mode, both the upper diagonal tensioning beam 3 and the lower diagonal tensioning beam 4 are single sheet and in a bent circular structure.
In an implementation mode, the upper diagonal tensioning beam 3 is connected to the top sheet 1 via a first weld seam 8, the upper diagonal tensioning beam 3 is connected to the surrounding sheet 2 via a second weld seam 9, the lower diagonal tensioning beam 4 is connected to the surrounding sheet 2 via a third weld seam 10, and the lower diagonal tensioning beam 4 is connected to the bottom sheet 6 via a fourth weld seam 11. The first weld seam 8, the second weld seam 9, the third weld seam 10, and the fourth weld seam 11 form a non-closed circular shape that is disconnected at one point.
In an implementation mode, the second weld seam 9 and the third weld seam 10 are arranged in parallel and spaced apart.
In an implementation mode, the internal tensioning member 5 includes a first connector, a rope-like tensioning beam, and a second connector. The first connector is provided on an inner surface of the top sheet 1, and the second connector is provided on an inner surface of the bottom sheet 6. The first connector and the second connector are connected by the rope-like tensioning beam.
In an implementation mode, two ends of the rope-like tensioning beam are respectively detachably connected to the first connector and the second connector.
In an implementation mode, the surrounding sheet 2 is provided with an air valve or an electric air pump.
The inner surface of the top sheet 1 is provided with a plurality of first connectors, and the inner surface of the bottom sheet 6 is provided with a plurality of second connectors corresponding to the first connectors. One end of the rope-like tensioning beam is non detachably connected to one of the first connectors, and the other end of the rope-like tensioning beam is non detachably connected to a corresponding second connector. The above technical solution is that the tensioning beam is non-detachably connected with the top sheet 1 and the bottom sheet 6, so that the inner surface of the top sheet 1 is integrated with the inner surface of the bottom sheet 6. The rope-like tensioning beam can increase a tensile strength of the tensioning beam, and can withstand greater tension compared to PVC (polyvinyl chloride) tape tensioning beam, with a longer service life. The first connector and the second connector are symmetrically arranged along a transverse central axis of the surrounding sheet 2, so that the tensioning beam symmetrically pulls the top sheet 1 and the bottom sheet 6 on the same longitudinal axis. The first connector is pulled by the tensioning beam and moved into the inflatable bed, a part of the top sheet 1 corresponding to the first connector is caused to move into the inflatable bed. The top sheet 1 forms a locally spaced concave shape, so that the concave convex shape formed by the top sheet 1 can improve the contact and comfort with the human body, and play a supporting role in the human body. Similarly, the second connector is pulled by the tensioning beam and moved into the inflatable bed, the bottom sheet 6 is driven to move into the inflatable bed, thereby forming a locally concave shape on a surface of the bottom sheet 6, improving the stability of a contact between the bottom sheet 6 and the ground, and preventing the bottom of the inflatable bed from being unstable due to expansion and protrusion of the bottom sheet 6. The structure of the first connector, second connector, and rope-like tensioning beam can refer to patent application number 202310913353. X.
The above is only specific implementation modes of the present disclosure, but the protection scope of the present disclosure is not limited to this. Any skilled person familiar with the technical field can easily think of changes or replacements within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
