However, in the case of a hard case suitcase, when the user's luggage is stowed in a state in which it is used or when it falls or falls during transportation, or when an impact is applied that exceeds the limit that the bag body can be elastically restored, the corner or corner is broken There is a problem that it can not be restored in reality and it makes the appearance worse.

Nevertheless, until now, there is no clear measure to fundamentally solve the problem of corners or corners of the bag body being damaged except the method of changing the material of the bag body.

In addition, traveler who has a lot of baggage often carries several suitcases at the same time using both hands, or various types of luggage should be carried with suitcases frequently. In this case, There was a problem that it was difficult to take actions such as using a telephone or taking out a ticket or cash.

Therefore, travelers may simply bundle several suitcases with straps or luggage, such as briefcases, simply by placing them on top of the suitcases or by placing them on the handle of the suitcases, but it is only temporary and limited There is a limit that can not be used universally because it can be used.

In order to solve this inconvenience, Korean Patent Laid-Open No. 10-2011-0107354 of the prior art discloses an apparatus and method for a self-stabilizing rolling-able travel bag assembly.

The prior art includes a first portion of the suitcase and a second portion of the suitcase wherein the attachment member couples the second portion of the suitcase to the first portion of the suitcase to form first and second portions Self-stabilization is carried out when the liquid crystal display panel is erected or tilted together and moved or stopped together.

While various embodiments are described with respect to the attachment member in the prior art, it is not only inconvenient to store or store separately when the travel bag is not fastened, but also remarkably improves the convenience compared to simply fastening the fasteners together with a strap And there is still a problem that it is difficult to universally apply to various types of various hydrates.

The travel bag 100 provided with the detachable binding means according to the present invention is a foldable and foldable type bag which is folded or dropped through a plurality of couplers 122 provided at corners and a connecting bar 124 which is deformed flexibly between them, It is possible to prevent breakage of the impact portion even if it is hit.

In addition, various kinds of hydrates 10 and the like can be easily and simply attached and fastened to the travel bag 100 according to the present invention through the detachable binding joint 130, and the travel bag 100 Can be easily and simply fastened together.

In order to realize these functions and objects, the travel bag 100 provided with the detachable binding joint according to the present invention may include the bag body 110, the damage prevention module 120, the binding joint 130, and the like .

The bag body 110 is a constituent element in which a storage space is formed in the bag body 110 so that a user's goods and the like are accommodated. The bag body 110 includes a breakage prevention module 120 including a coupler 122 and a connection bar 124, A suitcase of any shape, opening and closing structure and material can be used as long as it can be installed in the shape of a suitcase.

In other words, the bag body 110 according to the present invention can be made of a soft case type travel bag that maintains its shape by a skeletal structure such as a wire or a thin pipe, but also can be made of a plastic material in which the body itself is elastically deformed within a predetermined range Of hard case suitcase.

More specifically, the bag body 110 includes a first bag body 111 and a second bag body 112. When the first bag body 111 and the second bag body 112 are closed, And preferably forms an appearance of a substantially rectangular parallelepiped when closed.

Of course, the outer appearance of the bag body 110 may be cylindrical or various polygonal tubular shapes depending on the shape and design considerations of the internal storage space.

1 and 2, the bag body 110 according to the embodiment of the present invention includes a hard case travel bag, and includes a first bag body 111 and a second bag body 112 . At this time, the first bag body 111 and the second bag body 112 are formed as rectangular parallelepipeds which are respectively opened in a state where the facing surfaces are spaced apart from each other.

The breakage prevention module 120 is configured to protrude from the periphery of the bag body 110 so as to cover the edges and corners of the bag body 110 to prevent the edges or corners of the bag body 110 from being damaged by an external impact Element. Therefore, even if an external impact is applied to the travel bag 100, the bag body 110 can be prevented from directly colliding with the ground or the external structure.

Since the breakage prevention module 120 is provided in each of the first and second bag bodies 111 and 112 and has a similar structure and shape to each other, 2, the breakage prevention module 120 will be described while collecting the bag bodies 111 and 112 as the bag body 110 without specifically distinguishing them.

Here, the corner refers to an intersection point where two different surfaces of the bag body 110 meet, a corner is an intersection point where three different surfaces meet, a point corresponding to a vertex common to each surface, Point. The edges and corners described below are used in the above-mentioned meaning.

The breakage prevention module 120 may have any structure as long as it is formed along a corner or a corner of the bag body 110 and protrudes outward from the bag body 110 so as to receive an external impact directly .

1 and 2, the breakage prevention module 120 according to the embodiment of the present invention is provided in a rectangular shape in the front and rear edge regions of the first and second bag bodies 111 and 112 facing each other . However, since the front and rear surfaces of the first and second bag bodies 111 and 112 may have various shapes and shapes, the shape of the damage prevention module 120 may be variously changed.

The breakage prevention module 120 includes a plurality of couplers 122 and a plurality of connection bars 124. The breakage prevention module 120 may include a plurality of couplers 122 and a plurality of connection bars 124. [

The coupler 122 and the connecting bar 124 are made of a material that is elastically deformed within a predetermined range so that the coupler 122 and the connecting bar 124 are elastically deformed to absorb the shock and can be restored to the original shape. It is recommended to fabricate fiber reinforced plastic (FRP) with excellent tensile strength.

Here, glass fiber or carbon fiber can be used as a reinforcing material of the fiber reinforced plastic. Glass fiber is a mineral fiber made of melted glass in fiber shape and has heat resistance, flame retardance and chemical resistance, and has a strong tensile strength and low elongation. Carbon fiber is a fiber made by heating and carbonizing organic fiber in inert gas. It has heat resistance, impact resistance and chemical resistance. It is lighter than metal but also has elasticity and strength.

However, it is needless to say that the coupler 122 and the connecting bar 124 may be made of aluminum or titanium, which is a lightweight material, having excellent strength and elasticity, especially in a fine alloy.

The coupler 122 and the connecting bar 124 are manufactured with appropriate materials in consideration of the characteristics of the material and the size, the manner of handling and the specific use of the travel bag 100 as described above.

The coupler 122 is a component for preventing the corners and the corner portions of the travel bag 100 according to the present invention from directly colliding with the ground surface. The coupler 122 is fixed to a corner where the edges of the bag body 110 intersect, 110 at the corner portion thereof.

As shown in FIGS. 1 and 2, the coupler 122 according to the embodiment of the present invention has an overall shape of 'A' formed by bending both corners of a corner, (For example, the wheel portion at the lower end of the bag body 100) can be applied to a different shape depending on the function or the aesthetic factor depending on the forming position of the bag body 100. [

The coupler 122 is attached to the corner of the bag body 110 by dividing the coupler 122 into two pieces 122 and 122 ' It is preferable that the bag body 110 is coupled to each other with the interposition of the bag body 110 and then fixed firmly by bolting, snapping, welding or the like.

However, it is needless to say that the coupler 122 made of only one piece 122 may be positioned outside the bag body 110 and then fixed by bolts or the like.

As shown in FIGS. 2 and 3, the connecting bar 124 is a component for reducing or absorbing shocks when the trip bag 100 according to the present invention is bent or deformed during an external impact, and includes a coupler 122 coupled to a corner, A plurality of which are provided along the corners of the bag body 110 in such a manner that they are connected to each other.

The connection bar 124 may be formed in a cylindrical rod shape, and preferably, a straight pipe shape having a through hole in the longitudinal direction.

2, a part of the outer circumferential surface of the connecting bar 124 is closely inserted into the lead groove 110A formed in the bag body 110 along the corner so as to receive the connecting bar 124, The connection bar 124 is formed in the shape of a groove having a cylindrical cross section so as to be easily separated from the inlet groove 110A.

The connecting bar 124 inserted into the inlet groove 110A maintains the state of the bag body 110 protruding more than both sides of the bag body 110 forming the corner, 110 can be prevented from directly colliding with the ground or the external structure.

The connecting bar 124 and the coupler 122 are connected to each other in such a manner that the end of the connecting bar 124 is fitted into the insertion groove 122B formed at the end of the coupler 122 as shown in Fig. . At this time, the shape of the insertion groove 122B of the coupler 122 located outside the bag body 110 may be such that the half of the outer periphery of the connection bar 124 is surrounded by the connection bar 124 .

Thus, the connecting bar 124 can absorb the impact without being easily detached from the insertion groove 122B even when the connecting bar 124 is deformed due to an external impact (see FIG. 3).

The connecting bars 124 may be formed of connecting bars 124 having different lengths depending on the mounting position or the size and shape of the bag body 110.

At this time, the connecting bars 124 of different lengths adjacent to each other around the coupler 122 to which the external impact is applied are flexibly deformed (degree of elastic deformation) at a similar level so that the applied impact can be balancedly distributed. (Slenderness ratio, ratio of the length to the cross-sectional diameter) in the case of the adjacent connecting bar 124 to be formed.

That is, it is possible to manufacture the connecting bar 124 having the same slenderness in such a manner that the connecting bar 124 having a longer length has a larger sectional diameter and the connecting bar 124 having a smaller length has a smaller sectional diameter.

1 and 2, the breakage prevention module 120 according to the present invention includes a connection bar 124A which is received in a vertical direction corner (long edge) of the bag body 110, And a sub-coupler 123 connected to the sub-coupler 123.

2, the sub-coupler 123 is located at the center of the long connecting bar 124A to suppress excessive bending deformation of the connecting bar 124A, so that the connecting bar 124A is connected to the coupler 122 From being easily separated or separated from each other.

In addition, the sub coupler 123 divides one connecting bar 124A having a long length into upper and lower parts with reference to the sub coupler 123, and this causes the upper and lower connecting bars 124A As the bending deformation is made individually and independently, the impact can be distributed and reduced vertically and efficiently, efficiently and stably.

In other words, considering the slenderness ratio of the connecting bar 124, even if the connecting bar 124 having a long length is installed, it is possible to reduce the bending deformation (elastic deformation) similar to that of the adjacent connecting bars 124 It becomes unnecessary to increase the sectional diameter.

As a result, due to the sub-coupler 123, the breakage prevention module 120 according to the present invention is made lighter (due to a reduction in the cross-sectional diameter of the long connecting bar 124) It is not necessary to divide the bar 124 into the upper and lower connecting bars 124), and a sense of heterogeneity (a difference in appearance due to a difference in sectional diameter between adjacent connecting bars 124). And a structure having an appearance that is not beautiful without being formed.

The subcoupler 123 according to the embodiment of the present invention is formed so as to protrude more than the surface forming the corner of the bag body 110 in order to prevent the corner portion of the bag body 110 from directly colliding with the ground or the external structure And a sub-coupler insertion hole 123B through which the long connecting bar 124 passes.

Like the coupler 122 described above, the sub coupler 123 is divided into two pieces 123 and 123 ', respectively, as shown in FIG. 2, and are connected to each other through the bag body 110 on the outer side and the inner side of the bag body 110, And can be firmly fixed by bolting, snapping, welding, or the like.

Or the sub coupler 123 made of only one piece 123 formed with the sub coupler insertion hole 123B may be mounted on the outside of the bag body 110 and then fixed by bolts or the like.

Coupling grooves 110B are formed at positions where the sub coupler 123 is seated and fixed so as to reliably prevent the sub coupler 123 from flowing in a flexural deformation of the connection bar 124A. ) Can be further formed.

A handle coupler 125 connected to the left and right couplers 122 through the connecting bar 124 is provided at the handle H of the suitcase 100 according to the present invention. An insertion groove such as the coupler 122 is formed and the end of the connection bar 124 is inserted. At this time, it is preferable that the shape of the insertion groove of the handle coupler 125 is formed so as to surround at least a half of the outer surface of the connecting bar 124 on the cross section.

The process of absorbing the impact force applied to the corner of the travel bag 100 when the travel bag 100 according to the present invention drops on the ground will be briefly described with reference to FIG.

First, the coupler 122 at the lower end of the bag body 110 is elastically deformed to absorb some impact force, and the remaining impact force is transmitted to the travel bag 100 and the connecting bar 124. At this time, The compressive force in the longitudinal direction due to the elastic deformation of the bag body 110 and the coupler 122 is applied.

Next, the connection bar 124 is momentarily detached from the inlet groove 110A and elastically deformed to be further protruded from the edge of the bag body 110, thereby absorbing the impact force of the bag body 110. Accordingly, ) Is transmitted only a part of the impact force within the elastic limit (elastic limit), so that breakage of the corners and corner portions is prevented.

3, when the coupler 122 at the lower end of the bag body 110 is impacted with the sub-coupler 123, the lower connection bar 124A of the sub-coupler 123 is instantaneously inserted into the inlet groove 110A ), And as the bending deformation is made, the impact is reduced efficiently and stably as described above.

As shown in FIGS. 1 to 4, the binding unit 130 is another technical feature of the travel bag 100 according to the present invention. Various types of various baggage 10 and the like can be easily attached to the travel bag 100 It is a device that is designed to make it easy to attach and detach.

Here, the baggage 10 is a concept including not only a briefcase having a ring-shaped handle, a handbag or a name tag (see FIG. 1) but also the travel bag 100 itself according to the present invention. 130, respectively.

The binding member 130 according to the present invention has a structure in which one end is detachably coupled to one side of the connecting bar 124 and the other end is fastened to the baggage 10 (including the travel bag 100).

That is, the binding means 130 may have any form or structure as long as it is detachably connected to the connecting bar 124, which is the impact absorbing member, according to the present invention and the baggage 10.

The binding joint 130 according to the embodiment of the present invention includes a connecting bar fastening part 131 provided at one end and detachably fitted to and engaged with the outer periphery of the connecting bar 124, And a hydrate fastening part 136 provided at the other end of the hose to fasten the hydrate 10 in a ring shape.

The connecting bar fastening part 131 includes a connecting bar receiving part 132, a detaching knob 133, a detaching supporting part 134, and the like in order to detachably engage with the outer periphery of one side of the connecting bar 124 do.

First, the connecting bar receiving portion 132 is a component that is elastically deformed according to the external force of the user, and is attached to surround the outer periphery of the connecting bar 124 or removed from the connecting bar 124.

The connection bar accommodating portion 132 includes an insertion space S1 formed to be smaller than the cross sectional diameter of the connection bar 124 and at least half of the outer circumference of the connection bar 124 communicating with the insertion space S1 And the end of the U-shaped portion is folded inward to form a locking protrusion 132B.

When the user presses the connecting bar receiving portion 132 toward the connecting bar 124 in a state where the insertion space S1 and the connecting bar 124 face each other, The receiving portion 132 accommodates the connecting bar 124 in the receiving space S2 while being elastically deformed (the width of the inserting space S1 is expanded) along the outer periphery of the connecting bar 124. [

When the connecting bar 124 is received in the accommodating space S2 in such a manner that the width of the inserted space S1 is smaller than the sectional diameter of the connecting bar 124, It is possible to maintain the fastened state without detaching from the connecting bar receiving portion 132 within a range in which the elastic force of the connecting bar 132 is applied.

The ratio R2 / R1 of the width R1 of the insertion space S1 to the diameter R2 of the circle forming the accommodation space S2 varies depending on the elastic modulus (stress / strain) However, when the connecting bar receiving portion 132 is made of engineering plastic, it is preferable that the ratio (R2 / R1) is approximately 1.10 to 1.30.

That is, when the ratio is smaller than the above-mentioned ratio (R2 / R1), it is impossible to maintain a firm fastening force. When the ratio exceeds the above-mentioned ratio (R2 / R1) 124).

According to a specific embodiment, when the cross-sectional diameter of the connecting bar 124 is 7.5 to 8 mm, the diameter of the circle forming the receiving space S2 is approximately 8 mm, and the width of the inserted space S1 is 6.5 mm do.

The increase of the fastening force between the connecting bar receiving portion 132 and the connecting bar 124 can be achieved by fitting both sides to fit each other to increase the frictional force between both sides or to manufacture the connecting bar receiving portion 132 with a material having a high elastic modulus have.

Here, the meaning of 'fit tightly' means that not only the space formed between the outer periphery of the connection bar 124 and the accommodation space S2 physically coincides with each other but also the space between both sides is minimized The same can be understood in the following.

The increase in the fastening force between the connecting bar receiving portion 132 and the connecting bar 124 is achieved by forming a plurality of soft silicone protrusions having adhesive property on the inner surface of the connecting bar receiving portion 132 to be in contact with the connecting bar 124 .

In addition, at least one elasticity adjusting hole 132H may be formed at the center of the connecting bar receiving portion 132 so that the connecting bar receiving portion 132 is formed of a plurality of elastic rods 132A.

This structure not only contributes to the weight reduction of the connecting bar receiving portion 132 but also causes the elastic force to be applied only through the elastic rod 132A rather than the entire surface of the connecting bar receiving portion 132, do. That is, even the material having a high elastic modulus (aluminum or titanium) can be used as a material for the connecting bar accommodating portion 132 by forming the elasticity adjusting hole 132H.

 In addition, this structure allows the elastic rods 132A to be elastically deformed individually even in a position slightly offset from the insertion space S1 of the connecting bar 124 and the connecting bar receiving portion 132, S2) of the connecting bar 124. In addition,

The connecting bar receiving part 132 according to the embodiment of the present invention forms one elastic adjusting hole 132H at the center so that an elastic force acts through the pair of elastic rods 132A. However, it is needless to say that, unlike the embodiment, elastic deformation can be made individually through the three elastic rods 132A formed by forming two elasticity adjusting holes 132H in the center.

The locking protrusion 132B is a component for preventing the detachment of the connecting bar receiving portion 132 from the connecting bar 124 in the region dividing the insertion space S1 and the receiving space S2, The end portion of the engaging protrusion 132B is round-machined so that the portion 132 can be smoothly detached from the connecting bar 124. [

The detaching knob 133 is a component provided to easily detach the connecting bar receiving portion 132 fitted in the connecting bar 124 from the connecting bar 124. The detaching knob 133 is inserted into the insertion space S1 And is protruded outward at one end of the adjacent connecting bar receiving portion 132. [ At this time, it is preferable that the degree of protrusion of the detaching knob 133 is formed to be proportional to the size of the connecting bar receiving portion 132.

The detaching knob 133 according to the embodiment of the present invention is formed in accordance with a first curvature having a center in a direction opposite to a direction in which the connecting bar receiving portion 132 is attached to the connecting bar 124 through the insertion space S1 do.

The reason why the detaching knob 133 is formed so as to have a curvature according to the first curvature is that the connection bar receiving portion 132 is inserted between the bag body 110 and the detaching knob 133 So that the user can easily grasp the detachable knob 133 because the user's finger is easily fitted.

In this case, the degree of the first curvature (the inverse of the radius of curvature) is formed in inverse proportion to the overall size of the connecting bar receiving portion 132, but the degree of curvature is not excessively large, As long as a space in which the user's fingers can be easily fitted is secured.

Meanwhile, a plurality of slip prevention protrusions (not shown) protruding outwardly may be formed on the convex surface according to the first curvature, and the material is preferably made of soft silicone.

The detachable support portion 134 is inserted into the insertion space S1 so that the principle of the lever can be applied when the detaching knob 133 is pulled in the direction opposite to the attaching direction to detach the connecting bar receiving portion 132 from the connecting bar 124. [ And the other end of the connecting bar accommodating portion 132 adjacent to the detaching knob 133. [ At this time, it is preferable that the protruding degree of the detachable support portion 134 is formed to a degree proportional to the size of the connection bar accommodating portion 132.

With this structure, the detaching knob 133 is rotated about the end of the detaching support portion 134, and the connecting bar receiving portion 132 can be easily detached from the connecting bar 124.
