  "abstract": "A folding bed having a three section mainframe, a swinging left frame, a swinging right frame, these swinging frames hingedly attached on each end of a third stationary section at a mid portion of the mainframe. Foldaway legs are each hingedly connected near a longitudinal edge of the folding mainframe. These above features are in combination with a detachable middle support leg attaching to each third stationary section on the two longitudinal sides of the mainframe. A first structure element is attached to the head lateral side forming the head board, this structure element differing in design from a second structure element attached to the foot lateral side forming the foot board. The mattress support element on the mainframe is made up of independent rows of flexible metal structure running from one longitudinal side of the mainframe to its opposite corresponding longitudinal side. The mattress are inhibited from moving away from the folding mainframe by the foot board and the head board pressing on the mattress and by fasteners securing the mattress to the mainframe and also the head board to the mainframe when the bed is in the folded position.",
  "claims": [
    "1. A folding bed, comprising: a folding mainframe having two longitudinal and two lateral sides, a head and a foot lateral side, a foldaway leg hingedly connected near a longitudinal edge of the longitudinal sides of the folding mainframe, the two longitudinal sides having three sections, a swinging left frame, a swinging right frame, these swinging frames hingedly attached on each end of a third stationary section at a mid portion of the folding mainframe; a detachable middle support leg, the detachable middle support leg attaching to each third stationary section of the two longitudinal sides of the mainframe; a first structure element attached to the head lateral side, the structure element differing in design from a second structure element attached to the foot lateral side; a mattress; a mattress support element on the mainframe to support the mattress; and, fastening means to hold or release the first and second structure elements together and confine the mattress in place.",
    "2. The folding bed of claim 1 wherein the third stationary section is a mainframe connection channel bracket.",
    "3. The folding bed of claim 1 wherein the detachable middle support leg is arcuately triangular in shape.",
    "4. The folding bed of claim 1 further comprising a support shaft running from one middle support leg to the other.",
    "5. The folding bed of claim 1 wherein the first structure element is arched and urges on a lateral end of the mattress.",
    "6. The folding bed of claim 1 wherein the second structure element is arched and urges on a lateral end of the mattress.",
    "7. The folding bed of claim 1 wherein the second structure element tucks under the first structure element.",
    "8. The folding bed of claim 1 wherein the mattress support element comprise a plurality of independent rows of flexible metal structure running from one longitudinal side of the mainframe to its opposite corresponding longitudinal side.",
    "9. A folding mainframe comprising two longitudinal sides, two lateral sides, a head and a foot lateral side, a foldaway leg hingedly connected near a longitudinal edge of the longitudinal sides of the folding mainframe, having as improvement, each two longitudinal sides having three sections, a swinging left frame, a swinging right frame, these swinging frames hingedly attached on each end to a third stationary section at a mid portion of the folding mainframe in combination with a detachable middle support leg attaching to each third stationary section of the two longitudinal sides of the mainframe, a first structure element attached to the head lateral side, the structure element differing in design from a second structure element attached to the foot lateral side, a mattress support element on the mainframe supporting a mattress comprising a plurality of independent rows of flexible metal structure running from one longitudinal side of the mainframe to its opposite corresponding longitudinal side, and fastening means to hold or release the first and second structure elements together and confine the mattress in place.",
    "10. The folding bed of claim 9 wherein the independent rows of flexible material has a shape selected from the group consisting of different geometric shapes.",
    "11. The folding bed of claim 10 wherein the geometric shape is a chain of waves.",
    "12. The folding bed of claim 9 wherein the third stationary section is a mainframe connection channel bracket.",
    "13. The folding bed of claim 9 wherein the detachable middle support leg is arcuately triangular in shape.",
    "14. The folding bed of claim 9 further comprising a support shaft running from one middle support leg to the other.",
    "15. The folding bed of claim 9 wherein after attachment of the detachable middle support leg, top ends of the middle support leg urges on an underside of a top surface of the mainframe connection channel bracket, thereby covering the top ends of the middle leg.",
    "16. The folding bed of claim 9 wherein the first structure element is arched and urges on a lateral end of the mattress.",
    "17. The folding bed of claim 9 wherein the second structure element is arched and urges on a lateral end of the mattress.",
    "18. The folding bed of claim 9 wherein the second structure element tucks under the first structure element.",
    "19. The folding bed of claim 9 further comprising on two ends of the mid portion of the mainframe along the longitudinal sides, two arched rods running from one longitudinal side to the other longitudinal side of the mainframe, the rods not urging on the mattress support element when the bed is in the folded position."

  "description_excerpt": "This invention relates to a folding bed with a combined feature of having a detachable middle leg support for ease of transportation, a head and foot board urging on a mattress and a mattress support that lends itself to the movement of the user. The detachable middle support leg, being designed independent from the frame, can be shaped to any desired configuration to lend greater stability or aesthetic look to the bed when in use.\n\nFolding beds have become a necessity especially in homes, hotels and hospitals where additional beds are occasionally needed. Folding beds are designed to endure repeated folding and unfolding, should be easily transportable especially in this age where export and import between countries have become a salient part of commercial trade. Further, the folding beds should be easily set up and dismantled, easily folded and unfolded after assembly and should require as little storage space as possible.\n\nConventional folding beds usually have two pairs of middle vertically oriented legs which are permanently attached to the bed frame. As such, they require more space for transport and the legs stand the chance of being damaged during transport. These beds also do not have means of inhibiting the movement of the mattress from the mainframe and have mattress supports that provide tension during the folding of the mainframe and/or are uncomfortable to the user. Further, conventional beds do not have a way of indicating the head portion from the foot portion which may be important for some usage and for some individuals.",
