Description

The present invention relates to suitcases, especially large suitcases.

Suitcases having a lid attached to the case body via a hinge, wheels on the bottom, and a handle on the ceiling are known to have various structures (for example, Patent Document 1 (FIGS. 2 and 3). )reference).

Patent Document 1 will be described with reference to the following figure.
FIG. 7 is a side view of a conventional suitcase, and the suitcase 100 has a case body 101, a lid 102, and a hinge 103 as main elements. A plurality of wheels 105 are attached to the bottom 104 of the suitcase 100, a top handle 107 is attached to the ceiling 106 of the suitcase 100, and a side handle 108 is attached to the side surface of the suitcase 100.

With the wheels 105 on the floor 109, the user moves the heavy suitcase 100 sideways by pulling sideways while holding the top handle 107. The wheels 105 make lateral movement easy.
In addition, the user can grasp the top handle 107 or the side handle 108 and lift the suitcase 100.

The top handle 107 and the side handle 108 are attached to the center (including substantially the center) of the width W of the suitcase 100. Therefore, there is an advantage that the suitcase 100 does not tilt when lifted.

Further, the case body 101 is reinforced by a frame 111 having a U-shaped cross section at the opening edge, and the lid 102 is also reinforced by a frame 112 having a U-shaped cross section at the opening edge.
Since it is reinforced, there is an advantage that the opening edge is not damaged even if a hard object is applied to the opening edge when loading and unloading the luggage.

The suitcase 100 disclosed in Patent Document 1 has various advantages, but further improvement is desired.
FIG. 8 is an operation diagram of a conventional suitcase, and when loading and unloading luggage, the suitcase 100 is placed so that the case body 101 hits the floor 109 (or a table, a table, etc.). Next, the lid 102 is opened.

Since the depth D2 of the lid 102 is smaller than the depth D1 of the case body 101, a horizontally long triangular gap 113 is inevitably generated between the lid 102 and the floor 109 on the hinge 103 side.
When a heavy load is placed on the lid 102, the lid 102 bends, so that it is necessary to avoid loading a heavy load. Further, since the load applied to the lid 102 is directly applied to the hinge 103, it is necessary to increase the strength of the hinge 103.

In order to reduce the load on the hinge 103, it is effective to make the depth D1 of the case body 101 and the depth D2 of the lid 102 the same (including substantially the same).
Further, since it is desired to prevent the suitcase 100 from tilting when lifted, the top handle 107 is left attached to the center of the width of the suitcase 100 (including substantially the center).

Therefore, in a suitcase having a top handle in the center of the width, a structure capable of making the depths of the case body and the lid uniform is required.

Japanese Unexamined Patent Publication No. 2016-106891

An object of the present invention is to provide a structure in which the depths of the case body and the lid can be made uniform in a suitcase having a top handle in the center of the width.

The present inventor has long been involved in the manufacture of suitcases. The process examined to solve the problem will be described with reference to FIG.
FIG. 1 is a diagram showing an aspect of a suitcase in the examination process.
The suitcase 120 shown in (a) is of a type that opens and closes the fastener 121. Since the fastener 121 can be gently curved, the top handle 122 can be arranged at the center of the width of the suitcase 120, and the depth D1 of the case body 123 and the depth D2 of the lid 124 can be aligned. However, since the fastener 121 may be broken by a sharp object such as a screwdriver, there is a problem in terms of crime prevention.

The suitcase 130 shown in (b) is a band-shaped center frame 131 in which the opening edge of the case body 132 is reinforced, and is rich in crime prevention. Since the top handle 133 is provided on the center frame 131, the top handle 133 can be provided at the center of the width of the suitcase 130. On the other hand, since the depth D2 of the lid 13 is smaller than the depth D1 on the case body 132 side, the drawback as described with reference to FIG. 8 remains. That is, it is necessary to increase the strength of the hinge 135.

In the suitcase 140 shown in (c), the opening edge of the case body 141 is reinforced by the frame 142, and the opening edge of the lid 143 is reinforced by the frame 144, which is rich in crime prevention. The depth D1 of the case body 141 and the depth D2 of the lid 143 can be made uniform. On the other hand, the top handle 145 cannot be placed in the center of the width of the suitcase 140 in order to avoid interference with the frame 142. This causes the suitcase 140 to tilt when lifted. It is required to provide the top handle 145 in the center of the width.

By the way, the frames 142 and 144 having a U-shaped cross section are extruded products of light metal or resin. This extruded product is a straight part, and when bent, the U-shaped opening widens or the bent portion is wrinkled. Therefore, the frames 142 and 144 are used in the form of a straight line. The result is the form shown in FIG. 1 (c).

The present inventor has considered changing the extrusion molding method to an injection molding method. In the injection molding method, the molten resin is injected into the cavity of the mold and cured. The shape of the cavity can be set freely. By manufacturing the frame by the injection molding method, a non-linear frame can be obtained while maintaining a U-shaped cross section. From this knowledge, we have completed an invention that can solve the problem.

That is, the invention according to claim 1 comprises a case body and a lid body attached to the case body via a hinge, provided with wheels on the bottom, a top handle on the ceiling, and an opening edge of the case body. And the opening edge of the lid is a suitcase reinforced with a frame having a U-shaped cross section.
The depth of the case body and the depth of the lid are set to be the same.
The frame is bent so as to bypass the handle.

The invention according to claim 2 is the suitcase according to claim 1.
A side handle is attached to one of the side surfaces connecting the bottom and the ceiling, and the frame is bent so as to bypass the side handle.

The invention according to claim 3 is the suitcase according to claim 1 or 2.
The lid is characterized by having a lid that can be opened and closed.

The invention according to claim 4 is the suitcase according to claim 3.
The ceiling of the lid and the ceiling of the case body are connected by a buckle on the main body side, the ceiling of the lid and the ceiling of the lid are connected by a buckle on the lid side, and a buckle base is attached to the ceiling of the lid. The main body side buckle is rotatably attached to one end of the buckle base, and the lid side buckle is rotatably attached to the other end of the buckle base.

In the invention according to claim 1, the frame is bent to avoid interference between the top handle at the center of the width and the frame.
As a result, according to the present invention, in a suitcase having a top handle in the center of the width, a suitcase capable of aligning the depths of the case body and the lid is provided.

In the invention according to claim 2, the frame is bent to avoid interference between the side handle and the frame. The side handle can be placed in the center of the width of the suitcase.

In the invention according to claim 3, since the lid is provided with a lid that can be opened and closed, the lid can be opened to put in and take out articles while the lid is closed.

In the invention according to claim 4, a main body side buckle is provided at one end of the buckle base, and a lid side buckle is provided at the other end. Compared to arranging the main body side buckle and the lid side buckle separately, in the present invention in which the main body side buckle and the lid side buckle are integrated into a common buckle base, the number of parts can be reduced and the buckle can be attached. The man-hours can be reduced.

It is a figure which shows the mode of the suitcase in the examination process. It is a side view of the suitcase which concerns on this invention. It is a top view of the suitcase which concerns on this invention. FIG. 3 is a sectional view taken along line 4-4 of FIG. It is a comparison figure of the suitcase which concerns on this invention and the suitcase of another form. It is a figure explaining the modification of the suitcase which concerns on this invention, (a) is a plan view, (b) is a side view. It is a side view of a conventional suitcase. It is an action diagram of a conventional suitcase.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
The suitcase can be placed with the wide side of the case body facing down and the lid facing up, or the suitcase can be placed with the hinges facing down and the side handles facing up, but in the present invention, the wheels are facing down. Basically, the top handle is up, and the upper surface in this basic posture is called the ceiling, and the lower surface is called the bottom.

As shown in FIG. 2, the suitcase 10 has a case body 11, a lid 13 attached to the case body 11 via a hinge (FIG. 3, reference numeral 12), and a lid 13 attached to the case body 11. It is a container having a stopper 14 as a main element, and has a wheel 16 on the bottom 15, a top handle 18 on the ceiling 17, and a side handle 22 on the side surface 21 farthest from the hinge 12.

When the width of the suitcase 10 is W, the depth of the case body 11 is D1, and the depth of the lid 13 is D2, both D1 and D2 are half of W (including about half). D1 and D2 are set to be the same (including almost the same).
Strictly speaking, W = D1 + the wall thickness of the case body 11 + D2 + the wall thickness of the lid body 13, but the wall thickness of the case body 11 and the wall thickness of the lid body 13 are as thin as about 1 mm, so ignore them. Then, W = D1 + D2.

The top handle 18 is attached to the center of the width of the suitcase 10 (including substantially the center). When the top handle 18 is grasped by the user's hand and pulled up, the wheel 16 is separated from the floor 23. At this time, since the hanging point is in the center of the width of the suitcase 10 and the center of gravity of the suitcase 10 is substantially in the center of the width, the suitcase 10 does not tilt.

Preferably, the side handle 22 is also provided at the center of the width of the suitcase 10.
For that purpose, at the opening edge of the case body 11, the center in the height direction is projected in a trapezoidal shape. A side handle 22 is provided on the protruding trapezoidal portion 24.
The main body side frame 25, which is injection-molded into a shape that resembles the trapezoidal portion 24, is fitted into the opening edge of the case main body 11.

Relatedly, a recess 26 corresponding to the trapezoidal portion 24 is provided at the opening edge of the lid 13. The lid-side frame 27, which is injection-molded into a shape that resembles the recess 26, is fitted into the opening edge of the lid 13.
In this way, the main body side frame 25 and the lid side frame 27 are bent so as to bypass the side handle 22, whereby the side handle 22 can be arranged at the center of the width of the suitcase 10. It was.

Preferably, a part of the lid 13 is divided into a lid 31 that can be opened and closed. By providing the lid 31, it is possible to put in and take out small items by using the lid 31 while the lid 13 is closed, which enhances convenience.
The lower edge of the lid 31 is connected to the lid 13 by the sub hinge 32, and the upper edge of the lid 31 is fixed to the lid 13 by the lid side buckle 42.

As shown in FIG. 3, a top handle 18 is provided at the center of the width of the suitcase 10 on the ceiling 17. Then, two lid-side buckles 42 are provided so as to sandwich the top handle 18.
For that purpose, at the opening edge of the lid body 13, the central portion is made convex and protrudes toward the case body 11. A top handle 18 is provided on the protruding convex portion 33. Further, side recesses 34 and 34 are provided on both sides of the convex portion 33.

Relatedly, a rectangular concave portion 35 corresponding to the convex portion 33 is provided on the case main body 11 side, and side convex portions 36, 36 that fit into the side concave portions 34, 34 are provided on both sides of the rectangular concave portion 35.
Then, the lid side frame 27 having a meandering shape is fitted to the opening edge of the lid body 13, and the body side frame 25 having a meandering shape is fitted to the opening edge of the case body 11.
In this way, the lid side frame 27 and the main body side frame 25 are bent so as to bypass the top handle 18, whereby the top handle 18 can be arranged at the center of the width of the suitcase 10. It was.

Preferably, the buckle base 40 is fixed to the lid 13 at a portion along the side recess 34. A main body side buckle 41 is swingably attached to one end of the buckle base 40 in the front and back directions of the drawing, and a lid side buckle 42 is swingably attached to the other end in the front and back directions of the drawing.

When opening the lid 13 from the case body 11, the buckle 41 on the body side is raised toward the front of the drawing.
When opening the lid 31 from the lid 13, raise the lid side buckle 42 toward the front of the drawing.

As is clear from the figure, the tip of the side convex portion 36 extending from the case body 11 is close to the lid 31. The main body side buckle 41 is put on such a side convex portion 36. As a result, the buckle base 40 and the buckle 41 on the main body side can be miniaturized.
Further, as compared with arranging the main body side buckle 41 and the lid side buckle 42 separately, if the main body side buckle 41 and the lid side buckle 42 are integrated into the common buckle base 40, the number of parts can be reduced. , The buckle installation man-hours can be reduced.

As shown in FIG. 4, the main body side frame 25 has a U-shaped cross section and is fitted to the opening edge of the case main body 11. Preferably, an adhesive is applied to the opening edge of the case body 11 before fitting.
Similarly, the lid-side frame 27 has a U-shaped cross section and is fitted to the opening edge of the lid 13. Preferably, the adhesive is applied to the opening edge of the lid 13 before fitting.

The main body side frame 25 is a light metal molded product or a resin injection molded product that is stronger than the resin case main body 11. In the injection molding method, a cavity having an arbitrary shape is formed in the mold, and the molten resin is injected into the cavity and cured. Therefore, a non-linear frame can be obtained while maintaining the U-shaped cross section. The same applies to the lid side frame 27.

From the viewpoint of reinforcement, the frames 25 and 27 are required to be strong, but if the purpose is merely to protect the opening edge, the frames 25 and 27 are about the same as the case body 11 and the lid 13. It may be a strong material. Further, the frames 25 and 27 may be made of rubber or soft resin if the purpose is to alleviate the contact between the opening edges and to reduce the hitting sound. Therefore, the materials and strengths of the frames 25 and 27 may be arbitrarily selected.

By the way, the suitcase 10 is preferably used for overseas travel. At this time, it is required to receive the deposited suitcase 10 promptly and without mistake at the airport.
As shown in FIG. 5, it is assumed that the suitcase 120, the suitcase 10 according to the present invention, and the suitcase 130 are arranged side by side on the turntable 44.

Since the suitcase 10 has a shape feature in the frames 25 and 27, it can be distinguished from other suitcases 120 and 130.
That is, since many suitcases have a form similar to suitcases 120 or 130, they are not easy to identify and difficult to find quickly.
On the other hand, in the suitcase 10 of the present invention, since the frames 25 and 27 meander, it is easy to identify and can be quickly found.

In order to further improve the identification performance, the colors of the frames 25 and 27 may be different from the colors of the outer surfaces of the case body 11 and the lid 13. It is recommended that the colors of the frames 25 and 27 be more prominent (bright colors, chromatic colors) than the colors of the case body 11 and the lid 13. As a result, in addition to the identification performance, the design can be enhanced.

In addition, the suitcase 120 or 130 is provided with measures such as connecting a prominent handkerchief to the handles 122 and 133 and retrofitting a name tag. This is because the identification can be enhanced with a handkerchief or a name tag. However, there is a concern that handkerchiefs and name tags may come off during transportation.
In that respect, the frames 25 and 27 of the present invention do not come off during transportation.

Next, a modified example of the present invention will be described. The reference numerals of FIGS. 2 and 3 are used for the elements common to those of FIGS. 2 and 3, and detailed description thereof will be omitted.
As shown in FIG. 6B, in the suitcase 10 having the wheels 16 on the bottom 15, the top handle 18 on the ceiling 17, and the side handles 22 on the side surfaces 21, while holding the top handle 18 by hand, The frequency of lateral movement while rotating the wheel 16 is high. On the other hand, the side handle 22 is used less frequently.

From this point of view, as shown in FIG. 6A, the top handle 18 is arranged at the center of the width of the suitcase 10, and the frames 25 and 27 are bent so as to bypass the top handle 18. On the other hand, as shown in FIG. 6B, the side handle 22 is not arranged at the center of the width. By not arranging, the frames 25 and 27 can be made straight on the side surface 21.

Compared to the injection-molded frames 25 and 27, the extruded linear frames 25 and 27 are inexpensive.
By using the frames 25 and 27 shown in FIG. 6A as injection molded products and the frames 25 and 27 shown in FIG. 6B as extruded molded products, the cost of the suitcase 10 can be reduced.

In addition to making all of the frames 25 and 27 injection-molded products, it is permissible to make a part (a portion bypassing the top handle 18) an injection-molded product and the rest an injection-molded product.
In this case, the injection-molded product and the extruded product may be manufactured separately, fitted to the frames 25 and 27, and then the joint between the injection-molded product and the extruded product may be bonded. Adhesion may be either an adhesive or fusion welding. Further, the adhesion may be performed even before being fitted to the frames 25 and 27.

The suitcase of the present invention may be a trunk or a large bag having wheels on the bottom and a top handle on the ceiling, and is not limited to a suitcase in a narrow sense.

Further, in FIG. 2, the lid 31 may be fastened to the lid 13 with a fastener (FIG. 1A, reference numeral 121) so as to be openable and closable.

The present invention is suitable for suitcases with wheels on the bottom and top handles on the ceiling.
