Definitions

  • the present disclosure generally relates to products for aquatic sports and, more particularly, to an inflatable stand up board.
  • Inflatable stand up boards provide boarders with access to numerous aquatic activities. Surfboarders can stand or sit on the inflatable board and participate in numerous aquatic sports.
  • the inflatable stand up board can be designed to encompass various shapes, as needed, to achieve various functions.
  • the inflatable stand up board can be a surfboard for surfing, can be used with a paddle for paddleboarding when waves are not present, and can further be used as a flotation device for aided swimming.
  • the inflatable stand up board has the ability to support boarders and float on water due to air filled chambers therein. Unfortunately, due to collisions or impacts with external objects, inflation chambers can be damaged during use, causing air leakage and loss of buoyancy. This air leakage and loss of buoyancy presents a dangerous scenario for those using the board. Accordingly, there is a need to provide an inflatable stand up board that can prevent air leakage during use.
  • an inflatable stand up board comprising: a top layer with a first perimeter; a bottom layer with a second perimeter; a drop stitch layer coupled to and disposed between the top layer and the bottom layer, which is uniquely adapted to maintain the predetermined shape of the inflatable stand up board upon inflation; a first sealing sheet circumferentially surrounding the top layer and the bottom layer and coupled in an airtight fashion to the first perimeter and the second perimeter; and a second sealing sheet.
  • the second sealing sheet is disposed at least at the front end and the tail end of the inflatable stand up board (the two ends being on opposing sides of the board), and is coupled to at least a portion of the first perimeter and the second perimeter.
  • the second sealing sheet also overlaps at least part of the first sealing sheet.
  • the board's inflatable chamber is defined by the top layer, the bottom layer, and the first sealing sheet.
  • the second sealing sheet may comprise a front sealing sheet disposed at the front end of the inflatable stand up board and a tail sealing sheet which is disposed at the tail end of the inflatable stand up board.
  • the second sealing sheet will surround the circumference of the board such that the second sealing sheet spans the first perimeter and the second perimeter of the top and bottom layers respectively.
  • the first sealing sheet has a first lip and a second lip.
  • the first lip overlaps the first perimeter, forming a first border and the second lip overlaps the second perimeter forming a second border.
  • the second sealing sheet can overlap the first and second borders to provide additional securement.
  • an adhesive layer is disposed between the first sealing sheet and the second sealing sheet; the adhesive may cover all or a portion of the inner surface of the second sealing sheet.
  • the adhesive layer disposed between the first and second sheets may comprise: a first adhesive strip disposed proximate the first border, creating a first airtight connection at the first boarder; and a second adhesive strip disposed proximate the second border, creating a second airtight connection at the second border.
  • an adhesive layer is disposed between the first perimeter and the first lip, all of which overlap, creating an airtight connection.
  • another adhesive layer may be disposed between the second perimeter and the second lip, all of which overlap, creating another airtight connection.
  • the drop stitch layer comprises an upper base layer coupled to the top layer, a lower base layer coupled to the bottom layer, and tensioning members disposed between and coupled to the upper and lower base layers.
  • the upper base layer is coupled to the top layer via an adhesive layer disposed between the upper base layer and the top layer.
  • the lower base layer is coupled to the bottom layer via a separate adhesive layer disposed between the lower base layer and the bottom layer.
  • At least one of the adhesive layers is formed by curing a complex glue, which comprises a glue and a curing agent.
  • the cuing agent has a mass ratio between 5% and 10%.
  • the present disclosure also provides an inflatable stand up board, comprising: a top layer with a first perimeter; a bottom layer with a second perimeter; a drop stitch layer disposed between the top layer and the bottom layer, which is uniquely adapted to maintain the predetermined shape of the inflatable stand up board upon inflation; a first sealing sheet circumferentially surrounding the top layer and the bottom layer and coupled in an airtight fashion to the first perimeter and the second perimeter; a first sealing strip coupled to the top layer and the first sealing sheet; and a second sealing strip coupled to the bottom layer and the first sealing sheet.
  • the top layer, the bottom layer, and the first sealing sheet define the inflatable chamber of the inflatable stand up board.
  • the first sealing sheet has a first lip and a second lipwherein the first lip overlaps the first perimeter forming a first border, and the second lip overlaps the second perimeter forming a second border. Additionally, the first sealing strip overlaps the first border and the second sealing strip overlaps the second border.
  • a first adhesive layer is disposed between the first sealing strip and the first sealing sheet, creating a first airtight connection proximate the first border. Furthermore, a second adhesive layer is disposed between the second sealing strip and the first sealing sheet, creating a second airtight connection proximate the second border.
  • the inflatable stand up board achieves a double sealing effect, preventing air leakage.
  • the double sealing effect makes it difficult to puncture or damage the air seals or the side surface of the inflatable stand up board, meaning users can avoid dangerous conditions presented during deflation of an inflatable stand up board.

  • the inflatable stand up board 100 may further utilize an anti-slipping layer 12 disposed on the top layer 10.
  • the anti-slipping layer 12 is designed to contact a boarder's body and can be used to increase the friction coefficient between the board 100 and the body, decreasing the likelihood of slipping off the board during use.
  • the top layer 10 has a first perimeter 11 surrounding the circumference of the top layer 10.
  • the bottom layer 20 is typically in contact with the water, when in use, and has a second perimeter 21 surrounding the circumference of the bottom layer 20.
  • the first sealing sheet 40 acts as side surface of the inflatable stand up board, coupled to the top layer 10 and the bottom layer 20 at the first perimeter 11 and the second perimeter 21, thus forming airtight seals in both locations.
  • an inflatable chamber is formed in the board 100 which is defined by the top layer 10, the bottom layer 20, and the first sealing sheet 40.
  • the drop stitch layer 30 is disposed within the inflatable chamber and is uniquely adapted to maintaining a predetermined shape of the inflatable stand up board 100 upon inflation.
  • the inflatable stand up board 100 may include a fixing base 13.
  • the fixing base 13 is disposed on the top layer 10 and is depressed toward the bottom layer 20.

  • the inflatable stand up board 100 further comprises a second sealing sheet 50 in a ring shape, surrounding the top layer 10 and the bottom layer 20, and coupled in an airtight manner to the first perimeter 11 and the second perimeter 21.
  • the second sealing sheet 50 covers the first sealing sheet 40.
  • the second sealing sheet 50 is ideally constructed of the same or similar material as that of the first sealing sheet 40.
  • Both the first sealing sheet 40 and the second sealing sheet 50 are affixed in an airtight manner to the first and second perimeters 11 and 21, achieving a double sealing effect for the inflatable stand up board 100.
  • This double sealing effect prevents damage or puncture to the sidewalls of the board 100, thereby avoiding the dangerous condition of air leakage during use.
  • a plurality of sealing sheets can be disposed.
  • three or more sealing sheets can be disposed at the sides of the inflatable stand up board, such that the inner sealing sheets are covered by the outer sealing sheets, thus achieving an improved sealing effect.

  • the first border aa and the second border bb are protected from exposure to the outside environment via the second sealing sheet 50, which overlaps the first border aa and the second border bb (i.e., the second sealing sheet 50 covers the first sealing sheet 40 and the top layer 10 at the first border aa and the second sealing sheet 50 and bottom layer 20 at the second border bb).
  • This overlapping feature prevents external substances from contacting and damaging the first border aa and the second border bb, further preventing air leakage of the inflatable stand up board.
  • a third adhesive layer 63 is disposed between the first sealing sheet 40 and the second sealing sheet 50, which covers the inner surface of the second sealing sheet 50.
  • the result of the third adhesive layer 63 is such that the first sealing sheet 40 is fixedly coupled to the second sealing sheet 50.
