Abstract:
1. A patient bed, comprising: a supporting frame having a first caster wheel, a second caster wheel, a third caster wheel, and a fourth caster wheel; a rectangular middle section, mechanically connected to said supporting frame, having a top side, a bottom side, a left side, and a right side, wherein said middle section further includes a first lateral subsection and said second lateral subsection, wherein said first lateral subsection slidably connected to said right side of said rectangular middle section, said second subsection slidably connected to said left side of said rectangular middle section, and wherein said rectangular middle section further comprises an opening and a removable cover, said opening configured to allow a patient to excrete when said removable cover is opened; a top section, mechanically connected to said supporting frame and to said top side of said rectangular middle section, said top section further comprises a third lateral side and a fourth lateral side; a bottom section, mechanically connected to said supporting frame and to said bottom side of said rectangular middle section, said bottom section further comprises a fifth lateral section and a sixth lateral section; a first sliding assembly, mechanically connected to said rectangular middle section, said top section, and said bottom section on said right side of said rectangular middle section; a second sliding assembly, mechanically connected to said rectangular middle section, said top section, and said bottom section on said left side of said rectangular middle section, wherein said first sliding assembly and said second sliding assembly are operable to simultaneously push and lower said top section and said bottom section so that said patient bed transforms into a sitting chair; a first lateral top sliding assembly mechanically connected to a top side of said first lateral subsection; a first lateral bottom sliding assembly mechanically connected to a bottom side of said first lateral subsection, wherein said first lateral top sliding assembly and said first lateral bottom assembly are operable to simultaneously slide said first lateral subsection in and out underneath said rectangular middle section at a predetermined angle so as to change the width of said rectangular middle section; a second lateral top sliding assembly mechanically connected to a top side of said second lateral subsection; a second lateral bottom sliding assembly mechanically connected to a bottom side of said second lateral subsection, wherein said second lateral top sliding assembly and said second lateral bottom assembly are operable to simultaneously slide said second lateral subsection in and out underneath said rectangular middle section at said predetermined angle so as to change the width of said rectangular middle section; a third lateral top sliding assembly mechanically connected to a top side of said third lateral subsection; a third lateral bottom sliding assembly mechanically connected to a bottom side of said third lateral subsection, wherein said third lateral top sliding assembly and said third lateral bottom assembly are operable to simultaneously slide said third lateral subsection in and out underneath said top section at a predetermined angle so as to change the width of said top section; a fourth lateral top sliding assembly mechanically connected to a top side of said fourth lateral subsection; a fourth lateral bottom sliding assembly mechanically connected to a bottom side of said fourth lateral subsection, wherein said fourth lateral top sliding assembly and said fourth lateral bottom assembly are operable to simultaneously slide said fourth lateral subsection in and out underneath said top section at said predetermined angle so as to change the width of said top section; a fifth lateral top sliding assembly mechanically connected to a top side of said fifth lateral subsection; a fifth lateral bottom sliding assembly mechanically connected to a bottom side of said fifth lateral subsection, wherein said fifth lateral top sliding assembly and said fifth lateral bottom assembly are operable to simultaneously slide said fifth lateral subsection in and out underneath said top section at a predetermined angle so as to change the width of said bottom section; a sixth lateral top sliding assembly mechanically connected to a top side of said sixth lateral subsection; and a sixth lateral bottom sliding assembly mechanically connected to a bottom side of said sixth lateral subsection, wherein said sixth lateral top sliding assembly and said sixth lateral bottom assembly are operable to simultaneously slide said fourth lateral subsection in and out underneath said bottom section at said predetermined angle so as to change the width of said bottom section; wherein said first sliding assembly comprises a main bar, a first moving block, a second moving block, a top arm mechanically connected to said top section, a bottom arm mechanically connected to said bottom section, and a moving motor, wherein upon activation of said moving motor, said moving motor causes said first moving block and said second moving block are configured to move back and forth freely in a linearly manner along said main bar, when said first moving block and said second moving block move along said main bar from left to right, said top arm pushes said top section and at the same time said bottom arm pulls said bottom section downward, turning said patient bed into said sitting chair, wherein when said first moving block and said second moving block glides along said main bar from right to left, said top arm pulls section top section and at the same time said bottom arm pushes said bottom section, turning said sitting chair back to said patient bed, wherein said moving motor has a power of 28 watts and a speed of 40 rounds per minutes.
