Description

{HARD SIDE SUITCASE} < / RTI >

The present invention relates to a hard case travel bag including a center frame, and more particularly, to a travel case for a hard case which can provide a sufficient rigidity at the edge portion of the storage space and lighten the travel bag, To a hard case travel bag including a center frame which is configured to suppress the occurrence of plastic deformation of the bag body caused by the bag.

Travel bag is a bag used for storing and protecting travel goods, and it is widely used with wheels and handles. It is divided into a hard case and a soft case depending on the material of the bag body.

Soft Case The bag of the travel bag is mostly made of chemical fiber such as nylon, polyester, etc., and the wire is formed along the corner of the bag body to maintain its shape. The soft case travel bag is disadvantageous in that it can not be restored to its original state when the wire is bent by an external impact.

The hard case travel bag is currently the most popular type in the market, and the bag body itself is made of hard plastic so that it keeps its shape without a skeletal structure such as a wire. Since the bag body is rigid and elastic at the same time, It is excellent in protecting the object.

In relation to the hard case travel bag, Korean Patent Laid-Open Publication No. 2011-0056625 discloses a travel bag, and Japanese Laid-Open Patent Publication No. 2011-0056625 has a lid shell and a bottom shell connected to each other by a hinge, And the two fixtures are mounted on the cover shell of the side wall, and when the fixture is released, the fixtures are projected downward and outward to be provided as a gripping member when the bag is opened, Two wheels and a driving handle are provided for carrying the bag in the two-wheel mode.

As disclosed in Japanese Laid-Open Patent Publication No. 2011-0056625, the conventional hard case travel bag has a central frame made of a metal material for reinforcing the strength of both sides of the bag body to be opened and preventing the breakage even when the bag is repeatedly opened and closed .

However, since the conventional hard case travel bag is produced by bending a long metal bar in one direction in the central frame, a high strength due to a metal material can be secured, but a characteristic of a metal material having a large specific gravity Which is a major factor in increasing the load of the travel bag, thereby being recognized as a major obstacle to the light weight of the travel bag.

In addition, since the metal bar has a large difference in strength from both bag bodies formed of a synthetic resin material, if the external force acts on the vicinity of the metal bar and the bag body, the metal bar maintains its shape even if the bag body is elastically deformed. There has been a problem that plastic deformation occurs in the bag body in the vicinity of the joining of the bar and the bag body.

However, if the center frame is made of a synthetic resin material to solve the problem of the metal bar as described above, the rigidity of the bag body due to the center frame can not be formed at the edge of the bag body, There was a problem that it became impossible.

On the other hand, the hard case suitcase may be damaged when the user's baggage is stored, or when the shock is applied to the bag body beyond the limit that the bag body can be resiliently restrained during use or falling during transportation or when the corner or corner is broken or inward There is a problem that the damaged marks such as the white line or the crushed marks remain permanently even if they are restored.

Manufacturers of hard case suitcases have been performing corner drop tests on travel bags before they are marketed in an effort to minimize the problems described above. In the bottom drop test by the corner drop test, most of the travel bags in which the baggage is loaded collide with the floor, so that breakage of the wheel or breakage or collapse of the corner of the bag is commonly observed. There is no clear countermeasure to solve the problem of corners or corners being damaged except the method of changing the material.

In addition, although the elastic band for fixing the position of the article stored in the hard case travel bag is provided inside the storage space, the elastic band is often fixed to the bag body and is not easy to attach and detach, Even when the band is unnecessary, there is an inconvenience that the bag is attached to the bag body together with the goods and is caught by the hand when storing and withdrawing the goods. And had a usability problem that must be experienced.

1 and 2, a hard case travel bag 1 including a central frame according to an embodiment of the present invention is configured to have a rigidity at the edge of a storage space, And the bag body 10 and the center frame 30 are configured to suppress the occurrence of plastic deformation of the bag body 10 due to an external force at the edge portion of the storage space.

The bag body 10 is made of a hard case. The hard case travel bag is the most popular type on the market at present. Soft case that keeps shape by wire like skeleton Unlike travel bag, bag body itself is made of plastic, It has excellent function to protect the objects stored inside.

The bag body 10 comprises a first bag body 11 and a second bag body 12. The first bag body 11 and the second bag body 12 are configured to form a storage space therebetween with their edges facing each other. Preferably, the first bag body 11 and the second bag body 12 form an appearance of a substantially rectangular parallelepiped when closed. Of course, the outer appearance of the bag body 10 may be cylindrical or various polygonal tubular shapes depending on the shape and design considerations of the internal storage space.

An edge of the first bag body 11 and an edge of the second bag body 12 facing each other with the first bag body 11 and the second bag body 12 forming a storage space, Quot; region. &Lt; / RTI >

The center frame 30 has a structure for preventing deformation and breakage of the opposite edges of the first bag body 11 and the second bag body 12 and includes a first reinforcing module 31 and a second reinforcing module 32 ). The central frame 30 is made of a material other than metal such as synthetic resin and artificial fiber.

The first reinforcing module 31 is formed along the edge of the first bag body 11 and the second reinforcing module 32 is formed along the edge of the second bag body 12 do. The first reinforcing module 31 and the second reinforcing module 32 are brought into contact with each other while the bag body 10 is closed.

Each of the first reinforcing module 31 and the second reinforcing module 32 includes a connector J and a reinforcing member F. [

As shown in FIGS. 1 to 3, the connector J is fixed to the corners at the edges of the first bag body 11 and the second bag body 12 to reinforce the first connector body J1. And a second connection port J2.

The first connection port J1 is formed on the outer side of the bag body 10 and the second connection port J2 is formed on the inner side of the bag body 10. [ The first connection port J1 and the second connection port J2 are coupled to each other through the through hole 10h formed in the bag body 10. [

A first engaging portion U1 is formed in the first engaging portion J1 and a second engaging portion U2 is formed in the second engaging portion J2 to form a coupling force with the first engaging portion U1. The first engaging portion U1 and the second engaging portion U2 can form a coupling force by various coupling means such as bolt fastening, snap button, welding, or the like through the through hole 10h. In the embodiment of the present invention, it is explained that the coupling force is formed by bolt fastening.

As shown in FIG. 3, the first engaging portion U1 is formed to protrude to form a female screw thread to which a bolt (not shown) is fastened, and the second engaging portion U2 is formed as a through hole into which a bolt is inserted do.

The first engaging portion U1 is inserted into the through hole 10h formed at the corner portion of the outer edge of the bag body 10 and the bolt (not shown) is inserted from the inside of the bag body 10 into the second engaging portion The first connection port J1 and the second connection port J2 are fixed to the corners of the bag body 10 by the coupling force of the bolts when the first connection port U2 is screwed to the female thread of the first connection port U1.

3 and 4, the reinforcing member F reinforces the edge between the first bag body 11 and the joint J of the second bag body 12, and the first bag body 11 ) And the second bag body (12) along the edge of the second bag body (12).

As shown in Fig. 4, the reinforcing member F includes an inserting portion FI, a reinforcing portion FR, and a reinforcing bar FB.

The insertion portion FI is a portion into which the edges of the first bag body 11 and the second bag body 12 are inserted and is bent in such a manner that the end portion encloses the inside and the outside of the edge, And the edge of the second bag body 12 are inserted.

The insertion portion FI wraps the inserted edges of the first bag body 11 and the second bag body 12 between the corners to prevent damage to the edge portions due to external force and impact. The edge of the bag body 10 may be constrained to the insertion portion FI or adhered to the insertion portion FI while being inserted into the insertion portion FI.

The reinforcing portion FR extends from the insertion portion FI toward the storage space and is integrally formed with the insertion portion FI along the edge. The reinforcing part FR elastically deforms together with the bag body 10 and the insertion part FI when the elastic part is deformed by the external force of the edge part surrounding the insertion part FI and dissipates the external force, The resilient restoring force is formed so that the bag body 10 and the insertion portion FI can be returned to the original state.

The insertion portion FI and the reinforced portion FR are made of a synthetic resin material such as ABS resin (acrylonitrile butadiene styrene copolymer).

ABS resin is a styrene resin composed of three components of styrene, acrylonitrile and butadiene. It is easy to process, has high impact resistance, and has good heat resistance. Compared with polyethylene, heat resistance is about 93 degrees Celsius for 80 degrees Celsius and 4.5 for impact resistance values of 0.8. The impact resistance of 4.5 is used as a substitute for industrial parts such as automobile parts, helmet, electric parts, and spinning machine parts because it is strong enough not to break even when hit with a sledgehammer.

Inside the reinforcing portion FR, a hollow hole Fh is formed along the longitudinal direction, that is, the edge direction.

As shown in FIGS. 3 and 4, the reinforcing bar FB is configured to suppress the bending deformation of the reinforcing portion FR and is formed in the shape of a long bar in one direction, And is slidably inserted.

The reinforcing bar (FB) is made of glass fiber or carbon fiber material.

Glass fiber is a mineral fiber made of molten glass in the form of fibers and is resistant to high temperatures, does not burn, does not absorb, has low hygroscopicity, has chemical durability and therefore is resistant to corrosion, , The elongation is low, and the abrasion resistance is low. The reinforcing bar (FB) may be formed of fiber reinforced plastic (FRP) using glass fiber as a reinforcing material of plastic.

Carbon fiber is a fiber made by heating and carbonizing organic fiber in an inert gas. It is excellent in heat resistance, impact resistance, and chemical resistance. In addition, carbon fiber is lighter than metal, yet has excellent elasticity and strength.

The reinforcement bar FB suppresses the excessive elastic deformation of the bag body 10 and the insertion portion FI due to its own rigidity in the hollow hole Fh when an external force acts on the edge portion of the bag body 10. [

The reinforcing bars FB are formed of different materials having greater rigidity than the reinforcing portions FR and are slidably movable in the hollow holes Fh so that the reinforcement bars FR ) In the longitudinal direction.

This is because if the reinforcing bar FB mainly absorbs external force in the form of a tensile force or a contracting force, breakage of the travel bag 1 is likely to occur at both ends of the reinforcing bar FB when repeated external force is applied.

The conventional hard case travel bag is combined with a metal frame to prevent breakage even when the bag is repeatedly opened and closed by reinforcing the strength of the edges of both bag bodies, which are open to each other.

The hard case travel bag 1 including the center frame of the present invention is constructed such that the first reinforcing module 31 and the second reinforcing module 32 are formed of synthetic resin and man-made fibers, ) Can be made lightweight.

In addition, since the metal bar in the conventional hard case travel bag has a large difference in strength from both bag bodies formed of a synthetic resin material, when the external force acts on the vicinity of the metal bar and the bag body, There is a problem that plastic deformation occurs in the bag body in the vicinity of the joining of the metal bar and the bag body.

The hard case travel bag 1 including the center frame of the present invention is configured such that when the external force is applied, the insertion portion FI and the reinforcing portion FR are bent and deformed together with the edge of the bag body 10, The reinforcing bar FB suppresses the excessive bending deformation of the reinforcing portion FR while preventing plastic deformation of the bag body 10 in the vicinity of the joining of the frame 10 and the center frame 30, .

That is, the rigidity increases in the order of the bag body 10, the insertion portion FI, the reinforcing portion FR and the reinforcing bar FB, while the amount of elastic deformation due to the external force applied to the bag body 10 increases The external force transmitted from the bag body 10 to the reinforcing bar FB is gradually increased in proportion to the amount of deformation of the reinforcing bar FB in the order of the insertion portion FI, the reinforcing portion FR, and the reinforcing bar FB, The rigidity is maintained, and the small deformation of the bag body 10 is suppressed.

As shown in FIG. 3, the reinforcing bar FB projects outward at both ends of the reinforcing part FR, and the second connecting hole J2 is provided with an inlet (not shown) in which the end of the reinforcing bar FB is slidably inserted A portion U2a is formed.

Both ends of the reinforcing bar FB are inserted into both of the inlet portions U2a so that the slide movement and the flow are restricted so that the edge of the bag body 10 is inserted and coupled to the insertion portion FI.

As shown in FIG. 4, a packing member PA is fitted and fixed between the second deforming portion F2 and the reinforcing portion FR.

The packing member PA is inserted into the insertion portion FI of the second reinforcing module 32 while being fixed between the second deforming portion F2 and the reinforcing portion FR as shown in Figure 4 (b) As shown in Fig. 4 (a), the first bag body 11 and the second bag body 12 are interposed between the insertion portions FI with the edges of the second bag body 12 facing each other Thereby closing the storage space.

The reinforcing portion FR of the first reinforcing module 31 is formed with the first deformed portion F1 and the reinforcing portion FR of the second reinforcing module 32 is provided with the interposed portion A pair of second deformed portions F2 into which one deformed portion F1 is inserted are formed.

The first deformed portion F1 extends from the reinforcing portion FR of the first reinforcing module 31 toward the reinforcing portion FR of the second reinforcing module 32 as shown in Figure 4 (b) , And the end thereof is curved in a curved shape toward the reinforcing portion (FR) of the first reinforcing module (31).

The second deforming portion F2 extends from the reinforcing portion FR of the second reinforcing module 32 toward the reinforcing portion FR of the first reinforcing module 31, (FR).

4 (a), in the process of closing the bag body 10, the bent end portions of the first deformed portions F1 come into close contact with the opposite surfaces of the second deformed portions F2, The pair of second deformed portions F2 are pressed and opened, and the bent ends of the first deformed portion F1 are pressed and collapsed.

Therefore, when the bag body 10 is closed to form the storage space, the storage space is double-sealed by the first deformation part F1, the second deformation part F2, and the packing member PA from the outside, Even if the bag 1 is exposed to moisture such as rainwater for a long time, the moisture penetration into the storage space is firmly blocked.

As shown in FIGS. 5 and 6, the hard case travel bag 1 according to another embodiment of the present invention further comprises a composite frame 50.

The first engaging portion U1 is inserted into the through hole 10h formed at the edge portion of the bag body 10 from outside and the bolt passes through the second engaging portion U2 from the inside of the bag body 10 The first sub coupler Cs1 and the second sub coupler Cs2 are fixed to the edges of the bag body 10 by the coupling force of the bolts when the first and second couplers Cs1 and Cs2 are screwed into the female threads of the first coupling portion U1.

When the subcoupler Cs is formed at the long edge of the bag body 10, the bent portion of the connecting bar B is divided on the basis of the sub coupler Cs, The shock absorbing amount of the connecting bar B is increased in the vicinity of the corner of the bag body 10 to which the impact is transmitted by the collision with the bag body 10 and the impact transmitted to the bag body 10 is further reduced.

10, the second coupler C2 and the second sub coupler Cs2 are formed with a first band coupling portion CB1 to which an end of the elastic band EB is coupled, A second band coupling portion CB2 detachably coupled to the first band coupling portion CB1 may be formed at an end of the first band coupling portion CB1.

In the conventional hard case travel bag, a resilient band for fixing the position of the accommodated article is provided in the storage space. However, since the resilient band is often fixed in the bag body and is not easily fixed, Even when the band is unnecessary, there is an inconvenience that the bag is attached to the bag body together with the goods and is caught by the hand when storing and withdrawing the goods. And had a usability problem that must be experienced.

10, the hard case travel bag 1 including the central frame according to another embodiment of the present invention is characterized in that each end of the elastic band EB is connected to the first bag body 11 and the second bag And the second coupler C2 fixed to the body 12 so as to be detachably coupled to one another, thereby solving the problems of the conventional art as described above.

In FIG. 10, the first band coupling portion CB1 and the second band coupling portion CB2 are shown as male and female buckles, but various attachment and detachment methods such as hook coupling, snap button, and Velcro tape can be applied.

6, the connecting bar B includes a first connecting bar B1 connected to one of the couplers C and a second connecting bar B2 connected to the other coupler C And the first connecting bar B1 and the second connecting bar B2 may be respectively coupled to both sides of the sub coupler Cs. Although not shown in detail, insertion holes into which the first connecting bar B1 and the second connecting bar B2 are inserted are formed at both ends of the sub-coupler Cs.

When the connecting bar B is separated into the first connecting bar B1 and the second connecting bar B2, as the slenderness ratio increases due to the reduction in length, The shock absorbing amount of the first connecting bar B1 or the second connecting bar B2 is increased in the vicinity of the corner of the bag body 10 to be delivered and the impact transmitted to the bag body 10 is reduced.

As shown in FIG. 9, when the corner of the travel bag 1 collides against the ground at the time of dropping the travel bag 1, the impact force is absorbed primarily by the elastic deformation of the coupler C. Even if the coupler C primarily absorbs the impact force, a part of the impact force is transmitted to the travel bag 1 and the connecting bar B and the elastic bar of the bag body 10 and the coupler C A compressive force in the longitudinal direction is applied.

The connecting bar B is momentarily detached from the inlet groove 10a and is elastically deformed to be further protruded from the edge of the bag body 10 so that the impact force is absorbed by the bag body 10, Only some of the impact forces within the elastic limit (elastic limit) are transmitted to prevent breakage of the corners and edge portions. 9 shows a state in which the sub coupler Cs is formed at the side edge of the bag body 10 so that the connecting bar B is bent downward only under the sub coupler and is instantly released from the inlet groove.

A coupler C fixed to the lower end corners of the first bag body 11 and the second bag body 12 in the first composite frame 51 and the second composite frame 52, Respectively, the bag wheels W can be coupled.

According to the present invention, the reinforcing bar (FB) suppresses the bending deformation of the reinforcing portion (FR) in the hollow portion, so that the rigidity of the travel bag (1) can be reduced while forming sufficient rigidity at the edge portion of the storage space , And a center frame which is configured to suppress plastic deformation of the bag body (10) due to external force at the edge of the storage space.

Each of the ends of the elastic band EB is detachably coupled to the second coupler C2 to thereby provide a hard case travel bag 1 including a central frame configured to improve the usability of the elastic band EB .

The connecting bar B is further protruded from the edge of the bag body 10 when the bag body 10 is bent or deformed so that the bag body 10 can be folded or folded during use or during transportation, It is possible to provide the hard case travel bag 1 including the center frame made to prevent the corner or the corner from being broken or dented.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
