Description

BACKGROUND OF THE INVENTIONField of the Invention
• The present invention relates to a rucksack having a ventilation function, and more particularly to a rucksack having a ventilation function, which prevents a ventilation unit from being twisted, due to an article received in the rucksack, and a wearer's back from being drenched in sweat.
Description of the Related Art
• Generally, a rucksack, which is a kind of bag, is taken by a wearer on his/her back under the condition that articles are received in the rucksack, thus being easily carried. The rucksack includes a back panel formed on one surface, and shoulder straps installed at both sides of the back panel and put on wearer's shoulders, and thus firmly contacts a wearer's body even in activities having live motion, such as climbing or exercise, thereby being conveniently used.
• Since the back panel of the above rucksack is closely adhered to the wearer's back, when the wearer sweats on his/her back due to the activities, such as climbing or exercise, the back panel is then drenched in sweat and cannot be easily dried. Further, heat emitted from the wearer's back cannot be easily discharged to the outside due to the back panel closely adhered to the wearer's back, thus giving the wearer an unpleasant feeling.
• In the case that the wearer continuously wears the rucksack under the condition that the back panel is drenched in sweat, the wearer's back is inflamed and wearer's clothes stink with sweat.
• In order to solve the above problems, a rucksack, which includes a ventilation plate spaced from a back panel so that air is efficiently circulated to a wearer's back, has been contrived and used. Hereinafter, with reference to FIGS. 8 and 9, such a rucksack will be described.
• As shown in FIGS. 8 and 9, aconventional rucksack 100 includes aback panel 110, upper and lower supportingpanels 120 and 130 having the shape of a flat plate, made of a metal, and formed on upper and lower portions of theback panel 110, a pair ofsupporters 140 vertically disposed such that both ends of thesupporters 140 are respectively supported by the upper and lower supportingpanels 120 and 130, and aventilation plate 50 closely adhered to a wearer's back, made of a mesh, and provided with an upper end fixed to the upper portion of theback panel 110 and a lower end connected to both sides of the lower supportingpanel 130 so as to bend the lower supportingpanel 130 in an arc shape so that theventilation plate 50 can be spaced from theback panel 110 at a designated interval and a gap therebetween is well ventilated.
• In the above conventional rucksack, the upper and lower supportingpanels 120 and 130 are made of a metal and connected to theback panel 110 using rivets, and thus may be deformed due to the use for a long time. Further, when a heavy article is received in the rucksack, the rucksack may lean to one side of theventilation plate 50, thereby deteriorating the wearing feeling.
• Since theventilation plate 50, the upper and lower supportingpanels 120 and 130, and thesupporters 140 are integrally fixed to theback panel 110, it is not easy to wash the rucksack due to interference of the upper and lower supportingpanels 120 and 130 and thesupporters 140.
SUMMARY OF THE INVENTION
• Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a rucksack, which prevents a ventilation unit from being twisted, due to an article received in the rucksack, and a wearer's back from being drenched in sweat.
• It is another object of the present invention to provide a rucksack, which allows a wearer to easily adjust elastic power maintained by bending a lower fixing panel.
• It is another object of the present invention to provide a rucksack, which increases the bearing power of supporting rods so as to minimize the deformation of a back panel in the transversal direction.
• It is another object of the present invention to provide a rucksack, which maximizes the bearing power of supporting rods in all directions.
• It is another object of the present invention to provide a rucksack, which uniformly maintains the elastic power of a lower fixing panel due to the fixation of a ventilation unit and fixes and separates the ventilation unit to and from the lower fixing panel by a simple manner.
• It is another object of the present invention to provide a rucksack, which simply fixes a ventilation unit to a lower fixing panel so as to maintain the elastic power of the lower fixing panel.
• It is yet another object of the present invention to provide a rucksack, which allows a lower fixing panel to be supported at a strong bearing power so as to maintain the elastic power of the lower fixing panel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
• Now, preferred embodiments of the present invention will be described in detail with reference to the annexed drawings.
• FIG. 1 is a schematic exploded perspective view of a rucksack in accordance with one embodiment of the present invention, FIG. 2 is a schematic perspective view of the rucksack of FIG. 1 in an assembled state, and FIG. 3 is a schematic bottom view of the rucksack of FIG. 1.
• As shown in FIGS. 1 to 3, arucksack 100 of this embodiment includes a receipt part formed therein, aback panel 110 contacting a wearer's back, and aventilation unit 1 for spacing the wearer's back from theback panel 110 so that air can be efficiently circulated in a gap between theback panel 110 and the wearer's back. Further, theventilation unit 1 prevents therucksack 100 from being twisted due to the weight of therucksack 100, thus preventing the deterioration of the wearing feeling of therucksack 100.
• Theabove rucksack 100 includes theback panel 110 formed on one surface so that a wearer can carry the rucksack under the condition that the wearer's back contacts theback panel 110 after bearingshoulder straps 112 on both shoulders.
• Theventilation unit 1 allows theback panel 110 to be spaced from the wearer's back, when the wearer carries therucksack 100, so that air can be efficiently circulated in the gap between theback panel 110 and the wearer's back, thus preventing the wearer's back from being drenched with sweat and theback panel 110 from being wet with sweat.
• Theventilation unit 1 includes upper andlower fixing panels 10 and 20, made of synthetic resin, provided on upper and lower portions of theback panel 110 in the transversal direction by bonding or sewing, a pair of supportingrods 30 installed between the upper andlower fixing panels 10 and 20 and provided with both ends respectively inserted into the upper andlower fixing panels 10 and 20 so that the supportingrods 30 can contact theback panel 110 and thus be supported thereby, and aventilation plate 50, made of a mesh, spaced from theback panel 110 under the condition that the upper end of theventilation plate 50 is fixed to the upper portion of theback panel 110 and the lower end of theventilation plate 50 maintains the elastic power of thelower fixing panel 20 by bending thelower fixing panel 20 in an arc shape usingelastic fixtures 40 provided between the lower end of theventilation plate 50 and thelower fixing panel 20.
• Thelower fixing panel 20 supports the lower ends of the supportingrods 30 under the condition that the lower ends of the supporting rods are closely attached to theback panel 110, and spaces theventilation plate 50 from theback panel 110 due to the elastic power. The overall surface of thelower fixing panel 20 is firmly attached to the lower end of theback panel 110, thus preventing thelower fixing panel 20 from drooping even when a heavy article is received in therucksack 100.
• Theupper fixing panel 10 is fixed to the upper end of theback panel 110 parallel to thelower fixing panel 20, and allows the supportingrods 30 between the upper andlower fixing panels 10 and 20 to uniformly support the back panel a10, thus preventing theback panel 110 from drooping when the wearer carries therucksack 100.
• The supportingrods 30 are provided with both ends inserted into the upper andlower fixing panels 10 and 20, and support theback panel 110 so that theback panel 110 can maintain a uniform shape. Further, the supportingrods 30 prevent therucksack 100, spaced from the wearer's back by theventilation unit 1, from drooping. Preferably, the supportingrods 30 have a rod shape having elasticity.
• The supportingrods 30 cross each other in an X shape on the rear surface of theback panel 110, and are provided with both ends inserted into the upper andlower fixing panels 10 and 20, thus increasing the bearing power of theback panel 110 and further increasing the repulsive power and the bearing power of theback panel 110 even when theback panel 110 is warped in the transversal direction.
• Preferably, theventilation unit 1 may include at least one subsidiary supportingrod 32 installed on the rear surface of theback panel 110 in the longitudinal direction of therucksack 100 and provided with both ends inserted into the upper andlower fixing panels 10 and 20. Thesubsidiary supporting rod 32 further increases the repulsive power and the bearing power of theback panel 110.
• Theventilation plate 50 is fixed under the condition that it is spaced from theback panel 110, and is closely attached to the wearer's back and allows air to be efficiently circulated to the wearer's back when the wearer carries therucksack 100. Theventilation plate 50 is made of a mesh, through which air is efficiently circulated, and spaced from theback panel 110 under the condition that the upper end of theventilation plate 50 is fixed to the upper portion of theback panel 110 and the lower end of theventilation plate 50 maintains the elastic power of thelower fixing panel 20 by bending thelower fixing panel 20 in an arc shape using theelastic fixtures 40 provided between the lower end of theventilation plate 50 and thelower fixing panel 20.
• That is,adjustment strings 42, which are sewed on theback panel 110 when thelower fixing panel 20 is fixed to theback panel 110, are respectively inserted intofixing clips 44 formed on the lower portion of theventilation plate 50 such that a width between thefixing clips 44 is smaller than the length of thelower fixing panel 20, as shown in FIG. 2, and are pulled and fixed. Then, thelower fixing panel 20 is bent in an arc shape by the pulling force, and thus has elastic power. Thereby, theventilation plate 50 is spaced from theback panel 110, as shown in FIG. 3, thus forming a space, into which air is efficiently circulated.
• In order to adjust the distance between theback panel 110 and theventilation plate 50, the bending degree of thelower fixing panel 20 is determined by the degree of pulling theadjustment strings 42 by a wearer.
• The overall surface of thelower fixing panel 20 is fixed to theback panel 110. Therefore, although the wearer strenuously moves with therucksack 100 on his/her back under the condition that a heavy article is received in therucksack 100, it is possible to prevent theback panel 110 from being twisted or drooping due to the leaning of the article to one side. Thereby, therucksack 100 of the present invention is comfortably put on by the wearer.
• Preferably, theshoulder straps 112 are attached to theback panel 110 so as to be firmly fixed to therucksack 100. However, theshoulder straps 112 may be attached to the upper portion of theventilation plate 50 so as to improve the wearing feeling, and a cushion member may be attached to a part of theventilation plate 50, which contacts the wearer's shoulders and thus receives strong force applied thereto.
• When the distance between theback panel 110 and theventilation plate 50 is narrowed due to the lengthening or deforming of theback panel 110, theventilation plate 50, and thelower fixing panel 20 caused by the use of therucksack 100 for a long period of time, or the elasticity of thelower fixing panel 20 is reduced, the distance is re-adjusted using theadjustment strings 42 and thefixing clips 44. Thereby, therucksack 100 can be continuously and conveniently used regardless of the deformation.
• In order to wash therucksack 100, theventilation plate 50 is separated from thelower fixing panel 20 by removing theadjustment strings 42 from thefixing clips 44 of theelastic fixtures 40, and then the supportingrods 30 and the subsidiary supportingrod 32 are separated from the upper andlower fixing panels 10 and 20, thereby minimizing the interference in washing therucksack 100 and thus allowing therucksack 100 to be easily washed.
• FIG. 4 is a schematic exploded perspective view of a rucksack in accordance with another embodiment of the present invention, FIG. 5 is an enlarged perspective view of the portion "A" of FIG. 4, and FIG. 6 is a schematic bottom view of the rucksack of FIG. 4 in an assembled state.
• As shown in FIGS. 4 to 6, theelastic fixtures 40, for maintaining the elastic power of thelower fixing panel 20 by bending thelower fixing panel 20 in an arc shape so as to space theback panel 110 and theventilation plate 50, do not adjust adjustment strings using fixing clips, but maintain a designated elastic power by one simple attachment by a wearer.
• That is, each of theelastic fixtures 40 includes afastening member 40A formed on thelower fixing panel 20 and ahook member 40B formed on theventilation plate 50 such that a width between bothhook members 40B is smaller than a distance between bothfastening members 40A. Thereby, a wearer can simply fix and separate the lower portion of theventilation plate 50 to and from thelower fixing panel 20 in a one touch manner.
• Preferably, thefastening member 40A includes afastening groove 46, into which thehook member 40B is inserted, formed through one side thereof, and thehook member 40B includes aring 48 provided with one side fixed to theventilation plate 50 by asewing band 47 and the other side, i.e., the opened side having two terminals, inserted into thefastening member 40A.
• After thering 48 of thehook member 40B formed at one side of theventilation plate 50 is fastened into thefastening groove 46 of thefastening member 40A formed at one side of thelower fixing panel 20, thering 48 of thehook member 40B formed at the other side of theventilation plate 50 is pulled and fastened into thefastening groove 46 of thefastening member 40A formed at the other side of thelower fixing panel 20, as shown in FIG. 6, thereby simply and conveniently fixing the lower portion of theventilation plate 50 to thelower fixing panel 20. Here, since the width between the hookingmembers 40B is narrower than the width between thefastening members 40A, thelower fixing panel 20 is bent in a designated arc shape as much as the difference of widths, and thus maintains the elastic power. Thereby, theventilation plate 50 is spaced from theback panel 110 at a designated interval, as shown in FIG. 6, and thus air is smoothly circulated through the gap between theventilation plate 50 and theback panel 110.
• In order to separate thehook member 40B from thefastening member 40A, thehook member 40B is pushed in a direction opposite to the fixing direction, i.e., thering 48 is pushed to the outside of thegroove 46 of thefastening member 40A, thus being simply separated from thegroove 46.
• As described above, in therucksack 100 of this embodiment, theelastic fixtures 40 for maintaining a designated interval between theback panel 110 and theventilation plate 50 so as to allow air to be smoothly circulated into the gap therebetween are simply and conveniently assembled and disassembled in a hanging manner, and continuously keep the elastically bent state of thelower fixing panel 20 unless any external force is applied to theelastic fixtures 40.
• In order to obtain the greater bearing power than in the case that thelower fixing panel 20 is elastically bent in an arc shape by theelastic fixtures 40, therucksack 100 of the present invention may further include a supportingunit 22. The supportingunit 22 includes a fixinggroove 22a formed in thelower fixing panel 20 in the longitudinal direction, and an elastic supportingrod 22b, having elastic power so that it can be elastically supported in a bent state, connected to the fixinggroove 22a.
• The elastic supportingrod 22b of the supportingunit 22 increases the bearing power of thelower fixing panel 20 under the condition that lower fixingpanel 20 is bent by theelastic fixtures 40. Thereby, it is possible to completely prevent theback panel 110 from drooping when a heavy article is received in therucksack 100.
• As apparent from the above description, the present invention provides a rucksack having a ventilation function, in which the overall surface of a lower fixing panel of a ventilation unit is integrally fixed to the lower end of a back panel so as to prevent the ventilation unit from being twisted, due to the weight of an article received in the rucksack, and a wearer's back from being drenched in sweat due to use for a long time, thereby not leaning to one side or being twisted due to the spacing between the rucksack and a wearer's back even when a heavy article is received in the rucksack, and thus being stably and comfortably carried by the wearer.
• Further, since a wearer can adjust the elastic power between the back panel and the lower fixing panel using adjustment strings and fixing clips of elastic fixtures, the rucksack of the present invention prevents the deterioration of a ventilating effect of a ventilation plate of the ventilation unit and the twisting of the back panel and the ventilation plate against each other due to the decrease of the elastic power between the back panel and the ventilation plate even when the rucksack is used for a long time.
• Further, the ventilation unit further includes supporting rods crossing each other and at least one subsidiary supporting rod so as to increase the bearing power and thus minimize the deformation of the back panel in the transversal direction, thereby allowing the ventilation plate to stably support the rucksack even when a wearer, carrying the rucksack on his/her back, is in activities having live motion, such as climbing or exercise, and allowing the wearer to comfortably and stably use the rucksack.
• Further, the elastic fixtures for maintaining a designated interval between the back panel and the ventilation plate are simply assembled and disassembled in a hanging manner, such as a one touch manner, thus being easily and simply assembled and disassembled by a wearer and continuously keeping the regular interval between the back panel and the ventilation plate unless any external force is applied to the elastic fixtures.
• Further, since each of the elastic fixtures includes a fastening member with a fastening groove and a hook member with a ring, the ventilation plate is easily attached to and detached from the back panel by the wearer.
• Further, in the case that a supporting unit for maintaining the elastic power of the lower fixing panel is provided on the lower fixing panel, the lower fixing panel is supported at a higher bearing power.
• Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
