- Generally, backpacks contain various objects therein and allow users to conveniently carry them during leisure activities such as mountain climbing. As shown in
FIG. 1 , such abackpack 104 includes abackpack body 101 to contain objects therein, abackpad 102 which is provided on abackpack body 101 to be in close contact with the back of a user, and a pair ofshoulder straps 103 which is coupled to thebackpack body 101 to allow the user to carry the backpack on his/her shoulders. - Furthermore, a
pad 105 is provided on each of thebackpad 102 and theshoulder straps 103 of thebackpack 104 to make wearing the backpack comfortable for the user. Thepad 105 protects the back and shoulders of the user with thebackpack 104 and reduces the fatigue of the user who is burdened with the weight of thebackpack 104. - As such, the
pad 105 shown inFIG. 2 is provided in each of thebackpad 102 and theshoulder straps 103 of thebackpack 104. Typically, to impart softness to thepad 105, thepad 105 is made of polyethylene or polyurethane foam, which is called a sponge. - However, because the
conventional pad 105, which is used in each of thebackpad 102 and theshoulder straps 103 of thebackpack 104, is made of a typical elastic member such as a sponge, there are problems of unsatisfactory ventilation and moisture retention. As a result, when the user carries thebackpack 104 on his/her back for a long time, thebackpad 102 and theshoulder straps 103 become soaked with sweat and, as well, the user's back becomes hot. As such, thebackpack 104 is unpleasant to the user who carries thebackpack 104 on his/her back. In addition, in the case in which thepad 105 is soaked with sweat, the user tires more quickly due to the increased weight of thebackpack 104. - Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a cushion pad for backpacks which is provided in each of a backpad and a shoulder strap of a backpack and is made of a material that is light in weight and has superior ventilation, thus allowing a user to carry the backpack on his/her back more comfortably.
- In order to accomplish the above object, the present invention provides a cushion pad for backpacks, including: a net fabric provided on each of a backpad and a shoulder strap of a backpack; a porous filter placed inside the net fabric to dissipate heat to the atmosphere; and a sheet layered on a surface of the porous filter and inserted along with the porous filter into a space defined between the net fabric and the cloth of the backpack. The cushion pad provides ventilation and elasticity to each of the backpad and the shoulder strap of the backpack.
- In the present invention, the cushion pad having both the porous filter and the sheet is provided in each of the backpad and the shoulder strap of the backpack. Thus, when the backpack is in close contact with a user's body, the cushion pad efficiently dissipates heat generated from the user's body. Furthermore, the cushion pad has superior ventilation, thus preventing the backpad and the shoulder strap from being soaked with sweat.
- As such, the cushion pad having a double layered structure of the porous filter and the sheet improves the function of the backpad and the shoulder strap of the backpack, thus being more convenient to a user. Furthermore, the cushion pad of the present invention is lighter than conventional pads as well as has superior ventilation, thus preventing the backpack from being soaked with sweat, thereby being pleasant to the user who carries the backpack on his/her back.
- The above and other objects, features and advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 is a view showing a conventional backpack; -
FIG. 2 is a perspective view showing a cushion pad to be inserted into a backpad or shoulder strap of the backpack ofFIG. 1 ; -
FIG. 3 is a partially exploded view showing a backpack having a cushion pad according to an embodiment of the present invention; -
FIG. 4 is a sectional view taken along the line A-A ofFIG. 3 ; and -
FIG. 5 is a perspective view of the cushion pad for backpacks according to the present invention. - Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.
-
FIG. 3 is a partially exploded view showing abackpack 2 having acushion pad 1 according to an embodiment of the present invention.FIG. 4 is a sectional view taken along the line A-A ofFIG. 3 .FIG. 5 is a perspective view of thecushion pad 1 for backpacks according to the present invention. In thecushion pad 1 to be inserted into each of abackpad 3 andshoulder straps 4 of thebackpack 2, anet fabric 5 is provided on a portion of each of thebackpad 3 and theshoulder straps 4 which are in close contact with the back and shoulder of a user. Furthermore, thecushion pad 1 of the present invention includes aporous filter 6 which is placed inside thenet fabric 5 to dissipate heat to the atmosphere, and asheet 7 which is layered on a surface of theporous filter 6 and inserted along with theporous filter 6 into the space defined between thenet fabric 5 and thecloth 8 of thebackpack 2. Thus, thecushion pad 1 of the present invention provides superior ventilation and elasticity to thebackpad 3 and theshoulder straps 4 of thebackpack 2. Thesheet 7 may be made of polyurethane. Alternatively, thesheet 7 may be made of another material capable of supporting theporous filter 6 and ensuring the elasticity of thebackpad 3 and theshoulder straps 4 of thebackpack 2. In other words, thesheet 7 is not limited to a specific material, so long as the material is able to support theporous filter 6 and ensure the elasticity of thebackpad 3 and theshoulder straps 4 of thebackpack 2. - As such, the
cushion pad 1 of the present invention has a double layered structure of theporous filter 6 and thesheet 7 and is inserted into each of thebackpad 3 and theshoulder straps 4 of thebackpack 2. Here, thecushion pad 1 is shaped in a predetermined shape and inserted between thenet fabric 5 and thecloth 8 constituting each of thebackpad 3 and theshoulder straps 4. Thus, thecushion pad 1 is characterized in that superior ventilation is ensured by theporous filter 6 which is in contact with the user's body through thenet fabric 5. - As shown in
FIG. 3 , when thecushion pad 1 including both theporous filter 6 and thesheet 7 is provided on thebackpad 3 of thebackpack 2, heat generated from the user's body is efficiently dissipated to the atmosphere through theporous filter 6 while thebackpad 3 is in contact with the user's body. Furthermore, thecushion pad 1 provides superior ventilation to thebackpack 2, thus preventing thebackpad 3 and theshoulder straps 4 from being soaked with sweat. - As shown in
FIG. 4 , in the structure of eachshoulder strap 4 having thecushion pad 1, thenet fabric 5 is disposed inside theshoulder strap 4 which is in contact with the user's body. Theporous filter 6, made of a porous fabric, is provided inside thenet fabric 5 to dissipate heat through a number of pores provided in theporous filter 6. Thesheet 7 is layered on a surface of theporous filter 6 to support theporous filter 6 and have frictional force. Thecloth 8 of thebackpack 2, which is positioned at a side of thesheet 7, is coupled to thenet fabric 5 so that the space is defined between thecloth 8 and thenet fabric 5. - As such, in the
cushion pad 1 of the present invention inserted into each of thebackpad 3 and theshoulder straps 4 of thebackpack 2 to provide ventilation and elasticity to thebackpad 3 and theshoulder straps 4, as shown inFIG. 5 , theporous filter 6 defines a surface of thecushion pad 1, and thesheet 7, made of a material such as polyurethane and having a predetermined thickness, defines the other surface of thecushion pad 1. Theporous filter 6 is provided on each position of thebackpack 2 at which the user's body is in close contact with thebackpack 2. Thesheet 7 serves to support theporous filter 6 and provide elasticity to thebackpad 3 and theshoulder straps 4. - Furthermore, as required, the
porous filter 6 may be varied in density by controlling a foaming rate of a raw material such as polyurethane. In consideration of the manufacturing costs or weight of thebackpack 2, theporous filter 6 may be inserted alone into each of thebackpad 3 and theshoulder straps 4 of thebackpack 2 without thesheet 7. Furthermore, a well-known porous filter normally used in a dust collector may be used as theporous filter 6 of the present invention. - In the present invention, the
porous filter 6 of thecushion pad 1 efficiently dissipates heat outside thebackpack 2, thus being pleasant to the user when thebackpack 2 is in close contact with the user's body. In addition, because theporous filter 6 has superior ventilation, the user is prevented from feeling uncomfortable due to thebackpack 2 being soaked with sweat, and thecushion pad 1 is prevented from becoming heavy due to the sweat. Moreover, thecushion pad 1 enhances impact absorbing ability and ventilation performance of thebackpad 3 andshoulder straps 4 of thebackpack 2, thus ensuring a high-quality product. - As described above, the present invention provides a cushion pad for backpacks which has a double layered structure of a porous filter and a sheet and improves the function of a backpad and the shoulder straps of a backpack, thus being more convenient to a user. Furthermore, the cushion pad of the present invention is lighter than conventional pads and has superior ventilation, thus preventing the backpack from being soaked with sweat, thereby being pleasant to the user who carries the backpack on his/her back. Moreover, the cushion pad has superior impact absorption and ventilation, thus providing a high-quality product.
- Although the preferred embodiment of the present invention has 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 claim.
