The present invention relates to a foldable bed equipped with improved bed board, and more particularly, to a foldable bed having pivotably connected frames each equipped with bed board having multiple penetrating holes so as to allow good ventilation for the foldable bed and decrease the weight of the bed effectively.
The conventional foldable beds generally comprise two frames which are pivotably connected to each other, a board is put on each of the two frames to form a bed. The two frames are foldable relative to each other to reduce the space for storage and transportation. However, the bed board of the fordable bed has no comparatively good design for ventilation, the bed is not in good ventilation so that the user can't sleep comfortable and the bed is easily wet to propagate bacteria, and the weight of the bed can't be decreased effectively so as to produce the disadvantages for movement and storage.
Moreover, one of the pivotal structure between the two pivotably connected frames includes a shaft which extends through lugs on each of the two frames. The other pivotal structure includes a connection plate which extends through two pivotal members not sharing a common axis so as to connect the two frames together. In order not to be pivoted in reverse direction when the bed is fully extended, a securing sleeves are used to secure the pivotal structure. Alternatively, support members are used to support the pivotal structure to achieve the same purpose. However, the securing sleeves are exposed and affect the outer appearance of the bed. The use of the support members increases the number of parts used and the support members do not have satisfied features. Besides, the conventional foldable beds do not have a cover, and there is no proper design for storage of the boards. In addition, the boards are heavy and do not have apertures for ventilation. Furthermore, the conventional pivotal structure does not have sufficient functions to meet different needs such as to set a specific angle for the two frames.
The present invention intends to provide improvements for the shortcomings mentioned above.
The present invention relates to a foldable bed foldable bed equipped with improved bed board which comprises a first frame and a second frame pivotably connected. The first and second frames have a first board and a second board put thereon respectively. The first and second boards have multiple first holes respectively, the areas that the first holes and the second holes are located occupies ⅙ to ½ of the area of the first board and the second board respectively. A
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The second frame 20 has a second board 21 connected to a top 200 thereof. At least one second connector 22 is connected to the rear end of the second frame 20, in this embodiment, there are two second connectors 22. Each second connector 22 has a second pin hole 220 and a second aperture 221 which is located below the second pin hole 220. A pivot 30 extends through the first and second apertures 121, 221 to pivotably connect the first frame 10 to the second frame 20. When the first and second frames 10, 20 are pivotable about the pivot 30 and fully extended, a pin 31 extending through the first and second pin holes 120, 220.
In order to increase the ventilation feature for comfort and de-humidity reason and for reducing weight, in one embodiment, the first board 11 and the second board 21 are made by wood, and thickness of the first board 11 and the second board 21 are at least 5 mm respectively. The first board 11 has multiple first holes 110. The second board 21 has multiple second holes 210. The area that the first holes 110 are located occupies ⅙ to ½ of the whole area of the first board 11. The area that the second holes 210 are located occupies ⅙ to ½ of the whole area of the second board 21. Specifically, the first and second holes 110, 210 each are a circular hole, and the diameter of each of the first and second holes 110, 210 is 1.5 cm to 4.0 cm.
When the first and second frames 10, 20 are set to be horizontal, the first pin hole 120 is located above the first aperture 121, an angle A1 between a connection line “L1” between two respective centers of the first pin hole 120 and the first aperture 121 and a vertical line V1 is less than 5 degrees. The second pin hole 220 is located above the second aperture 221, an angle A2 between a connection line “L2” between two respective centers of the second pin hole 220 and the second aperture 221 and the vertical line V2 is less than 5 degrees. The first connectors 12 and the second connectors 22 respectively protrude beyond the front end 101 of the first frame 10 and the rear end 201 of the second frame 20. Therefore, the first and second frames 10, 20 can be fully folded in horizontal direction for convenience of storage. The first and second frames 10, 20 each are a rectangular frame. There are two legs 13 on the rear end 102 of the first frame 10, and one leg 13 on the front end 101 of the first frame 10. The front end 202 of the second frame 20 has two legs 13, and rear end 201 of the second frame 20 has one leg 13. All of the legs 13 are able to be separated from the first and second frames 10, 20.
As shown in
In order to reinforce the structural strength of the first and second connectors 12, 22, the cross section of each first connector 12 is a U-shaped cross section, and the cross section of each second connector 22 is a second U-shaped cross section. The bridge plate between the two first side walls 122 is fixed to the front end 101 of the first frame 10, and the bridge plate between the two second side walls 222 is fixed to the rear end 201 of the second frame 20.
A first cover 40 is mounted to the first board 11 and a second cover 50 is mounted to the second board 21. The first cover 40 has a U-shaped first side panel 41 and the second cover 50 has a U-shaped second side panel 51. A first cover board 42 is connected to the top edge 410 of the first side panel 41. A first room 44 is defined between the first cover board 42 and the first side panel 41. A second cover board 52 is connected to the top edge 510 of the second side panel 51. A second room 44 is defined between the second cover board 52 and the second side panel 51. When the first board 11 and the second board 21 are folded to each other, the first bottom edge 411 of the first side panel 41 contacts the second bottom edge 511 of the second side panel 51. When the first frame 10 and the second frame 20 are respectively accommodated in the first and second rooms 44, 54, the first side panel 41 includes a first opening 43, and the second side panel 51 has a second opening 53. When the first and second boards 11, 21 are extended relative to each other, the first opening 43 is matched with the second opening 53.
The first frame 10 has a support 15 which is located between the first and second frames 10, 20 when the first and second boards 11, 21 are folded relative to each other.
In order to provide more functions to meet different needs, the first frame 10 has a first support member 60 and the second frame 20 has a second support member 70. The first support member 60 is driven by a first linear driving member 61 so as to be pivoted relative to the first frame 10. The second support member 70 is driven by a second linear driving member 71 so as to be pivoted relative to the second frame 20.
Furthermore, the first support member 60 is pivotably connected to a third support member 62. When the first support member 60 is pivoted an angle relative to the first frame 10, a pivotal portion between the first and third support members 60, 62 protrudes relative to the first frame 10. A third board 80 is connected to the first frame 10 and a fourth board 90 is connected to the second frame 20. When the first support member 60 and the second support member 70 are respectively pivoted relative to the first frame 10 and the second frame 20, the third board 80 and the fourth board 90 are respectively pivoted relative to the first and second boards 11, 21.
Again, for ventilation comfort and weight reasons, the third board 80 and the fourth board 90 are made by wood. The third board 80 has multiple third holes 81, and the fourth board 90 has multiple fourth holes 91. The area that the third holes 81 are located occupies ⅙ to ½ of the whole area of the third board 80. The area that the fourth holes 91 are located occupies ⅙ to ½ of the whole area of the fourth board 90.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
