Abstract

An embodiment mobility for delivering articles includes a frame defining a body of the mobility, a chain member coupled to a first side of the frame, wherein the chain member has a closed curve shape along an up-down direction, is movable relative to the frame, and includes a standby section provided at a fixed position with respect to the frame irrespective of a movement of the chain member, wherein the standby section includes a plurality of bent areas, a tray member having a first side coupled to the chain member, the tray member being movable in connection with a movement of the chain member, a wheel coupled to a lower portion of the frame, and a driver configured to provide a driving force to the chain member.

First claim

What is claimed is:

1. A mobility for delivering articles, the mobility comprising:
a frame defining a body of the mobility;
a chain member coupled to a first side of the frame, wherein the chain member has a closed curve shape along an up-down direction, is movable relative to the frame, and comprises a standby section provided at a fixed position with respect to the frame irrespective of a movement of the chain member, wherein the standby section comprises a plurality of bent areas;
a tray member having a first side coupled to the chain member, the tray member being movable in connection with a movement of the chain member;
a wheel coupled to a lower portion of the frame; and
a driver configured to provide a driving force to the chain member.

2. The mobility of claim 1 , further comprising a coupling unit coupled to the first side of the frame and comprising one or more rotary members provided revolvably, wherein the standby section of the chain member comprises sections configured to engage with the rotary members of the coupling unit.

3. The mobility of claim 2 , wherein:
the rotary members comprise a first rotary member and a second rotary member disposed above the first rotary member; and
the bent areas comprise:
a first bent area in which the chain member extends downward and is then bent upward after surrounding a lower area of the first rotary member; and
a second bent area in which the chain member that passes through the first bent area and extends to the second rotary member extends upward from the first rotary member to the second rotary member and is then bent downward after surrounding an upper area of the second rotary member.

4. The mobility of claim 3 , wherein:
the rotary members further comprise a third rotary member disposed below the second rotary member; and
the bent areas further comprise a third bent area in which the chain member that passes through the second bent area and extends to the third rotary member extends downward from the second rotary member to the third rotary member and is then bent upward after surrounding a lower area of the third rotary member.

5. The mobility of claim 4 , wherein:
the rotary members further comprise a fourth rotary member disposed above the third rotary member; and
the bent areas further comprise a fourth bent area in which the chain member that passes through the third bent area and extends to the fourth rotary member extends upward from the third rotary member to the fourth rotary member and is then bent downward after surrounding an upper area of the fourth rotary member.

6. The mobility of claim 5 , wherein:
the rotary members further comprise a fifth rotary member disposed below the fourth rotary member; and
the bent areas further comprise a fifth bent area in which the chain member that passes through the fourth bent area and extends to the fifth rotary member extends downward from the fourth rotary member to the fifth rotary member and is then bent after surrounding a lower area of the fifth rotary member.

7. The mobility of claim 6 , wherein:
the first rotary member is disposed behind the second rotary member;
the second rotary member is disposed behind the third rotary member; and
the third rotary member is disposed behind the fourth rotary member.

8. The mobility of claim 7 , wherein the fifth bent area has a shape that is bent rearward after surrounding the lower area of the fifth rotary member.

9. A mobility for delivering articles, the mobility comprising:
a frame defining a body of the mobility, the frame comprising:
an up-down extension area having a shape extending in an up-down direction, the up-down extension area comprising:
a front up-down extension area disposed at a front of the frame; and
a rear up-down extension area disposed at a rear of the frame; and

a front-rear extension area having a shape extending in a front-rear direction, the front-rear extension area comprising:
an upper front-rear extension area configured to connect an upper end of the front up-down extension area and an upper end of the rear up-down extension area; and
a lower front-rear extension area configured to connect a lower end of the front up-down extension area and a lower end of the rear up-down extension area;

a chain member coupled to a first side of the frame, wherein the chain member:
has a closed curve shape along the up-down direction;
is movable relative to the frame; and
comprises a standby section provided at a fixed position with respect to the frame irrespective of a movement of the chain member, wherein the standby section comprises a plurality of bent areas; and
comprises a first chain member having the closed curve shape extending sequentially along longitudinal directions of the front up-down extension area, the upper front-rear extension area, the rear up-down extension area, and the lower front-rear extension area;

a tray member having a first side coupled to the chain member, the tray member being movable in connection with a movement of the chain member;
a wheel coupled to a lower portion of the frame;
a driver configured to provide a driving force to the chain member; and
a coupling unit coupled to the first side of the frame and comprising one or more rotary members provided revolvably, wherein the standby section of the chain member comprises sections configured to engage with the rotary members of the coupling unit.

10. The mobility of claim 9 , wherein the chain member further comprises a second chain member having the closed curve shape extending sequentially along the longitudinal directions of the rear up-down extension area and the lower front-rear extension area, wherein the second chain member extends upward along the rear up-down extension area and then extends downward after being bent in an area facing the upper end of the rear up-down extension area, and extends forward along the lower front-rear extension area and then extends rearward after being bent in an area facing a front end of the lower front-rear extension area.

11. The mobility of claim 10 , wherein:
each of the front up-down extension area, the rear up-down extension area, the upper front-rear extension area, and the lower front-rear extension area is provided in a pair respectively in a left area and a right area of the frame; and
the frame further comprises a left-right extension area connecting the left area and the right area of the frame.

12. The mobility of claim 10 , wherein the tray member comprises:
a plurality of rods each having a shape extending in a left-right direction and sequentially arrayed along the front-rear direction; and
a link module coupled to left and right end portions of the plurality of rods, wherein the link module comprises a plurality of links sequentially arrayed along the front-rear direction and two neighboring links of the plurality of links are coupled rotatably relative to each other.

13. The mobility of claim 12 , wherein:
the tray member further comprises a connection block provided in at least one of the plurality of links of the link module; and
the tray member is coupled to each of the first chain member and the second chain member through the connection block.

14. The mobility of claim 13 , wherein the connection block comprises:
a front connection block disposed in a front area of the link module and coupled to the first chain member; and
a rear connection block disposed in a rear area of the link module and coupled to the second chain member.

15. The mobility of claim 12 , wherein the tray member further comprises an upward protruding block that protr
