Definitions

  • This invention relates to a sleeping bag, more particularly to a sleeping bag having a shell body with a pull string which can be drawn to adjust the shape of the shell body so as to fit different users.
  • Fig. 1 shows a conventional mummy-style sleeping bag, which is formed with an inner volume for fittingly accommodating the user's body.
  • the sleeping bag cannot fit users of varying height and build.
  • another conventional sleeping bag 1 is proposed, as shown in Fig. 2, and includes a plurality of resilient rings 13 formed by elastic bands or threads, which are stitched to an outer shell body 10.
  • the resilient rings 13 are displaced from one another from a head end portion 11 to a foot end portion 12 such that the outer shell body 10 can be constricted suitably to fit around the user's body in use.
  • the sleeping bag 1 is disadvantageous in that freedom of movement of the user and comfort of the sleeping bag 1 are relatively limited.
  • Fig. 3 shows still another conventional sleeping bag 2, which has a V-shaped opening that is formed in a chest portion 21 of an outer shell body, and that is covered with a fabric 25.
  • Two zipper tracks 22,23 of a zipper unit are respectively stitched to two edges 210,211 of the opening such that a slide fastener 24 is movable to close the zipper unit so as to bring the edges 210,211 to displace toward each other.
  • the inner volume of the sleeping bag 2 at the chest portion 21 is adjustable. However, this adjustment is limited so that the sleeping bag 2 is not suitable for different users.
  • the object of the present invention is to provide a sleeping bag with an accommodation chamber the volume of which can be adjusted conveniently so as to fit different users.
  • the sleeping bag includes an elongated shell body which is made from a flexible material, and which defines an accommodation chamber therein.
  • the accommodation chamber extends in a longitudinal direction of the shell body for receiving a user therein, and has an opening for access to the accommodation chamber.
  • the shell body includes head and foot end portions which are disposed opposite to each other along the longitudinal direction, which are proximate to and distal from the opening, respectively, and which correspond in position to the user's head and feet, and a middle portion which is disposed between the head and foot end portions.
  • the middle portion has a front major area which defines first and second tightened lines that are spaced apart from each other in one of the longitudinal direction and a transverse direction relative to the longitudinal direction.
  • a plurality of first eyelets are displaced from one another along the first tightened line.
  • a plurality of second eyelets are displaced from one another along the second tightened line.
  • a pull string is disposed to successively and alternately pass through the first and second eyelets such that pulling of the pull string brings the first and second tightened lines to displace toward each other in a respective one of the longitudinal and transverse directions.
  • the first preferred embodiment of a sleeping bag 3 is shown to be a mummy-style bag, and comprises an elongated shell body 30 which is made from a flexible material, and which defines an accommodation chamber 31 therein.
  • the accommodation chamber 31 extends in a longitudinal direction of the shell body 30 for receiving a user therein, and has an opening 32 for access to the accommodation chamber 31.
  • the shell body 30 includes head and foot end portions 300,303 which are disposed opposite to each other along the longitudinal direction, which are proximate to and distal from the opening 32, respectively, and which correspond in position to the user's head and feet, and a middle portion 301 which is disposed between the head and foot end portions 300,303.
  • the middle portion 301 has a front major area 304 which defines first and second tightened lines 4 that are spaced apart from each other in a transverse direction relative to the longitudinal direction and that extend parallel to each other.
  • a plurality of first tabs 40 and a plurality of second tabs 40 are stitched to the front major area 304.
  • the first tabs 40 are displaced from one another along the first tightened line 4, and are formed with first eyelets 401.
  • the second tabs 40 are displaced from one another along the second tightened lines 4, and are formed with second eyelets 401.
  • a pull string 5 with first and second ends 50,51 is disposed to successively and alternately pass through the first and second eyelets 401 in such a manner that the pull string 5 is extended through the first eyelet 401 at a first position of the first tightened line 4 nearest to the head end portion 300, the second eyelet 401 at a second position of the second tightened line 4, the first eyelet 401 at a third position of the first tightened line 4, the second eyelet 401 at a fourth position of the second tightened line 4, the first eyelet 401 at a fifth position of the first tightened line 4, and the second eyelet 401 at a fifth position of the second tightened line 4, and is then extended through the first eyelet 401 at a fourth position of the first tightened line 4, the second eyelet 401 at a third position of the second tightened line 4, the first eyelet 401 at a second position of the first tightened line 4, and the second eyelet 401 at a first position of the second tightened line 4.
  • first and second ends 50, 51 hang loosely at the first and second eyelets 401 at the first positions.
  • the first and second ends 50,51 can be pulled to bring the first and second tightened lines 4 to displace toward each other in the transverse direction, thereby placing the pull string 5 in a tensioned state, as shown in Fig. 5.
  • the first and second ends 50,51 can be tied into a knot or tightened in position by a conventional fastening means such that the pull string 5 can be held in the tensioned state.
  • the shell body 30 can be constricted appropriately by pulling of the first and second ends 50,51 of the pull string 5 such that the shell body 30 fits comfortably around the user's body for enhanced warmth.
  • Fig. 6 shows the second preferred embodiment of a sleeping bag 3 according to this invention.
  • the sleeping bag 3 is a rectangular bag and includes a rectangular shell body 31 with a front major area 304 at the middle portion 301.
  • the front major area 304 has proximate and distal regions 305,306 relative to the head end portion 300 and corresponding to the trunk and the legs of the user.
  • the first and second eyelets 401 are arranged to extend from the proximate region 305 to the distal region 306.
  • a third tightened line 7 is defined at the foot end portion 303 and extends in the transverse direction to join the first and second tightened lines 4.
  • At least one third tab with a third eyelet 70 is disposed at the third tightened line 7 to permit the pull string 5 to pass therethrough between the first and second eyelets 401 at a last position.
  • pulling of the pull string 5 can bring the third tightened line 7 to displace towards the head end portion 300 in the longitudinal direction, thereby adjusting the length of the shell body 31.
  • this embodiment can fit users of different height.
  • a pocket 81 is disposed adjacent to the head end portion 300 for receiving the exposed first and second ends 50,51 of the pull string 5.
  • Fig. 8 shows the fourth preferred embodiment of this invention.
  • the first and second eyelets 401 are disposed at the proximate region 305.
  • the distal region 306 defines fourth and fifth tightened lines 8 which are spaced apart from each other in the transverse direction.
  • a plurality of fourth tabs with fourth eyelets 80 are displaced from one another along the fourth tightened line 8.
  • a plurality of fifth tabs with fifth eyelets 80 are displaced from one another along the fifth tightened line 8.
  • the distal region 306 defines a sixth tightened line 9 which is disposed at a position remote from the proximate region 305 and which extends in the transverse direction to join the fourth and fifth tightened lines 8.
  • At least one sixth tab with a sixth eyelet 90 is disposed at the sixth tightened line 9 to permit the pull string 5 to pass therethrough between the fourth and fifth eyelets 401 at a last position such that pulling of the pull string 5 can bring the fourth and fifth eyelets 80 to displace toward each other in the transverse direction, and can bring the sixth tightened line 9 to displace toward the head end portion 300 in the longitudinal direction.
  • the fourth and fifth tightened lines 8 define a distance (W1) which is larger than a distance (W2) between the first and second tightened lines 4.
  • W1 which is larger than a distance (W2) between the first and second tightened lines 4.
  • the sleeping bag when configured as a mummy-style bag which has a tapered shell body 31 from the middle portion 301 to the foot end portion 303, the distance between the fourth and fifth tightened lines 8 is slightly larger than the distance between the first and second tightened lines 4.
  • Fig. 10 shows the sixth preferred embodiment of a sleeping bag according to this invention.
  • the front major area 304 of the middle portion 301 has three sets of eyelets 401,70 (each set including a plurality of first and second eyelets 401 and a third eyelet 70) which are displaced from one another in the longitudinal direction.
  • Three pull strings 5 are disposed to pass through the eyelets 401,70 of each set in a manner as described herein above so as to separately adjust three parts of the middle portion 301 which correspond in position to the chest region, the abdominal region and the leg region of the user.
  • the seventh preferred embodiment of a sleeping bag according to this invention is shown to have first and second tightened lines 4 which are spaced apart from each other in the longitudinal direction, and which extend in the transverse direction such that pulling of the pull string 5 can bring the first and second tightened lines 4 to displace toward each other in the longitudinal direction.
  • seventh and eighth tightened lines 6 are defined respectively on two lateral ends 307,308 of the front major area 304 opposite to each other in the transverse direction, and extend in the longitudinal direction to join the first and second tightened lines 4.
  • seventh and eighth tabs with seventh and eighth eyelets 60 are disposed on the seventh and eighth tightened lines 6, respectively, to permit the pull string 5 to pass therethrough such that pulling of the pull string 5 can bring the lateral ends 307,308 to displace toward each other in the transverse direction.
