Abstract
Abstract The convertible chair and load carrier device includes a dorsal member, a load support member pivotally mounted on the dorsal member, and a harness for attaching the dorsal member on the back of a user person. The load support member can be pivoted between first and second positions and locked in either one of these two positions. In its first position, the load support member is capable of supporting a load to thereby allow the user person to carry it on his back. In the second position of the load support member, this member forms the seat of a chair and the dorsal member the back of the same chair.

Claim 1
Independent Claim
375 words
A convertible chair and load carrier device, comprising: a dorsal member being, in use, generally vertical and having front and rear, opposite faces; means for attaching said dorsal member on the back of a user person with said front face thereof resting on the back of the said user person; a load support member with first and second opposite faces, and with a proximate end; and means for securing the proximate end of the load support member to said dorsal member either in (a) first position in which the load support member extends rearwardly of the dorsal member and is generally perpendicular to the said dorsal member to form an L-shaped load carrier device, wherein in the first position the first face of the load support member is an upper face and is generally horizontal so that a load to be carried by the user person can be disposed thereon and (b) a second position in which the load support member extends forwardly of said dorsal member to form a chair having a seat constituted by the second face of the load support ;member and a back constituted by the front face of the dorsal member; said means for securing the proximate end of the load support member to said dorsal member comprising means for separating the proximate end of said load support member from the said dorsal member; said convertible chair and load carrier device having two sides, and said means for securing the proximate end of the load support member to the dorsal member in the first or second position comprises on each side of the said device: (i) said dorsal member formed with a lower projection; (ii) an open slot made in said lower projection of the dorsal member; (iii) fastener means including a rod traversing said open slot for securing the proximate end of the load support member to said dorsal member; (iv) a groove made in one of the said lower projection of the dorsal member and proximate end of the load support member; and (v) a stud formed on the other of the said lower projection of the dorsal member and proximate end of the load support member, said stud being structured to slide in to the said groove.

A convertible chair and load carrier device, comprising: a dorsal member being, in use, generally vertical and having front and rear, opposite faces; means for attaching said dorsal member on the back of a user person with said front face thereof resting on the back of the said user person; a load support member with first and second opposite faces, and with a proximate end; and means for securing the proximate end of the load support member to said dorsal member either in (a) first position in which the load support member extends rearwardly of the dorsal member and is generally perpendicular to the said dorsal member to form an L-shaped load carrier device, wherein in the first position the first face of the load support member is an upper face and is generally horizontal so that a load to be carried by the user person can be disposed thereon and (b) a second position in which the load support member extends forwardly of said dorsal member to form a chair having a seat constituted by the second face of the load support ;member and a back constituted by the front face of the dorsal member; said means for securing the proximate end of the load support member to said dorsal member comprising means for separating the proximate end of said load support member from the said dorsal member; said convertible chair and load carrier device having two sides, and said means for securing the proximate end of the load support member to the dorsal member in the first or second position comprises on each side of the said device: (i) said dorsal member formed with a lower projection; (ii) an open slot made in said lower projection of the dorsal member; (iii) fastener means including a rod traversing said open slot for securing the proximate end of the load support member to said dorsal member; (iv) a groove made in one of the said lower projection of the dorsal member and proximate end of the load support member; and (v) a stud formed on the other of the said lower projection of the dorsal member and proximate end of the load support member, said stud being structured to slide in to the said groove.
Claim 3
Dependent Claim
256 words
A convertible chair and load carrier device, comprising: separable dorsal member and load support member, said dorsal member being, in use, generally vertical and having front and rear opposite faces, and said load support member having first and second opposite faces and a proximate end; means for attaching the dorsal member on the back of a user person with said front face thereof resting on the back of the user person; said dorsal member and said proximate end of the load support member being respectively provided with first and second, mutually mating connecting systems, wherein said second connecting system is capable of detachably engaging the first connecting system to fixedly secure the load support member to the dorsal member in a first position in which the load support member extends rearwardly of the dorsal member and is generally perpendicular to said dorsal member to form an L-shaped load carrier device, in which first position the first face of the load support member is an upper face and is generally horizontal so that a load to be carried by the user person can be disposed thereon, and wherein said second connecting system is capable of detachably engaging the first connecting system to fixedly secure the load support member to the dorsal member in a second position in which the load support member extends forwardly of the dorsal member to form a chair having a seat constituted by the second face of the load support member and a back constituted by the front face of the dorsal member.
