VI. Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a suitcase, and more particularly to a towable suitcase generally referred to as a trunk with casters. [Prior Art] The luggage case generally includes a receiving body having a plurality of wheels and a retractable handle, wherein the retractable handle slides between the storage position and the deployed position. The storage position means that the handle is stored in the handle. The inside of the container makes the suitcase not bulky. The unfolding position means that the handle extends out of the container to facilitate the towing of the suitcase. Such a suitcase is disclosed in U.S. Patent Application Publication Nos. 2002/0096410 and 2002/0139628, or International Patent Application No. 1/78548. However, these types of suitcases have a number of disadvantages. First, the mechanism that can retract the suitcase is usually mounted in the housing. ^ As a result, the mechanism of the handlebars usually takes up a lot of space and takes up space in the body, thus making the capacity of the container smaller. Therefore, the traveler must choose not to have a retractable handle and a suitcase to carry the item. The heavy or semi-rigid trunk of the right-hander, such as clothes, etc., will be indented by this structure, especially when the baggage is too heavy. Secondly, it can be observed that the traveler often makes the baggage too heavy. Excessive weight affects the handlebars and the load-bearing structure (especially the base and extension)

1314046 12993PIF Retractor), especially when towing the baggage phase, after several years of use (or after several years) due to fatigue, it may be seen in the handlebar mechanism and/or the receptacle and/or more often in the load-bearing structure To the crevices. Under repeated towing, swaying and bending the luggage, the soft, quality material (especially fibers) and the valleys fixed to the pole and the load-bearing structure may even tear away from the fixed point of the mechanism. Reinforcement can be provided, but it can complicate the process and increase the cost of the luggage. Moreover, the process of such a suitcase is extremely complicated because it must be drilled in the upper wall of the receiving body and fixed from the inside. The structure can hide the contents (4) and then transfer the contents, and often install an internal or equivalent. This is also called reinforcement. Installation _ is not cheap and is not easy to automate. [Invention] The aim is to overcome the above and other shortcomings and to provide a soft or semi-rigid towable suitcase which is more robust, has a higher capacity of the same volume of the container, and has a simpler and more For the above purposes, the towable suitcase of the present invention comprises: a mounting body fixed to the box frame, the box frame is located outside the receiving body and comprises: a base, provided with a plurality of a caster, wherein the base comprises a platform on which the receiving body is placed, and a frame extending along the vertical direction of the resisting body; and a σ, - contractible arm leaning against the base, wherein the contractible f is provided with a handle and Extending in the direction of an almost vertical platform. The combination of the housing and the frame is thus particularly simple.

1314046 The 12993PIF box on the outside of the body does not overlap or rarely overlaps the container to aid in capacity utilization. ^ ^ In addition, assuming that the frame provides most of the luggage's robustness, it does not take into account the robustness of the container, which facilitates process simplification and does not increase costs. The receiving body preferably includes a mating box frame and a lower portion seated in the box frame. Thus, the combination of the valley body and the box frame, depending on the interactive fixed mode, exhibits intrinsic strength. More specifically, the housing includes, for example, a panel that is fixed to the side arm of the rack and a bottom that is fixed to the platform. Moreover, in order to increase the strength of the reinforced luggage stand, the base preferably includes a leg that protrudes from the lateral side of the bracket to extend the lateral length of the bracket. The housing is thereby fixed to the foot column. According to a particular embodiment of the invention, the transverse direction of the platform and the support is: a bezel-shaped partition _, on which a plurality of casters are mounted. Therefore, the casters mounted on the frame rather than on the receiving body exhibit better stability, and the strength of the accommodating body is not required to be conventionally provided in the trunk. The collapsible arm includes, for example, a sheath for the base, slidably mounting a struts of a free end handle. The base includes, for example, a single set of chassis forming at least a portion of the platform, a frame and a sheath to provide better robustness and Process simplified suitcase. ▲ In accordance with a particular embodiment of the invention, the sheath is secured to the receptacle. The sleeve is at least partially (or entirely) sleeved in the recess of the rear wall of the housing, so that the capacity of the luggage compartment can be kept tight or not.

1314046 PIF 12993PIF

Moreover, the 'retractable arm' is preferably a curved shape with a concave surface facing the receiving body to facilitate the swinging of the luggage when it is towed. The container is made of, for example, a foam formed by a heat shrinking process, preferably polyethylene foam of various densities. The above and other objects, features and advantages of the present invention will become more <RTIgt; [Embodiment] Referring to Fig. 1, a towable suitcase 1 includes a housing 2 and a box 3' housing 2 attached to the box frame 3.

More specifically, in one embodiment, the front panel 6 extends downwardly into a partition 24 that engages the lower edge 25 of the front panel 6. When the partition 24 is fixed to cover the lower wall 23, the lower edge 25 forms a connection relationship of the front panel 6 corresponding to the bottom portion 22. In order to open the receiving body 2, the engaging plate 15 fixing the front panel 6 to the side wall 7 may be provided with a sliding closing member, and when the sliding closing member is opened, the side wall is unwound from the front panel 6 and thus the front panel 6 is wound. The lower wall 23 pivots. As shown in Fig. 1, the housing 2 further includes an auxiliary storage bag 26 and a small outer convex plate 28 which are integrally formed by the recess 27 in the front panel 6. In the present embodiment, the small outer convex plate 28 can have a rectangular appearance. The annular joint frame 29 is provided with a slide closing member, and the auxiliary storage bag 26 is opened by the small outer convex plate 28 partially unwound from the front panel 6. The small outer convex plate 28 is fixed to the concave portion 27 by the annular joint frame 29. The front and rear panels 6'5, the side walls 7 and the bottom portion 22 are made of a hard material to ensure that the grain storage body 2 provides sufficient protection and effectively protects objects placed in the cabinet from collision. The front and rear panels 6' 5 'side wall 7 and bottom portion 22 may be formed of a thermoplastic molding material to provide substantially the hardness of the container 2, however, the front and rear panels 6, 5, the side walls 7 and the bottom portion 22 are preferably coated with a glue. A thermoset foam of woven fabric. The front and rear panels 6, 5, side walls 7, and bottom portion 22 are each produced by hot pressing. As a result, the housing 2 has an attractive appearance (due to the appearance of the housing 2)

The upper weave) and also has a good hardness (due to the foam), at least enough to keep the container 2 in its original shape and hardly fixed to the frame 3 in most cases, as will be described later. The material used to form the container 2 may be, for example, polyethylene foam of various densities. In addition to the hot pressing process for determining the general shape of the housing 2, the slits 20, 21 may be formed by further pressing at the edges of the rear panel 6'5 and the side walls 7. The frame 3 includes a base 30' and a base 30 is provided with a pair of coaxial casters 31, 32. As shown in Fig. 1, the base 30 is provided with a platform 33 having a rectangular appearance and having a surface 34 for receiving the upper surface of the receiving body 2. The platform 33 includes an extension extending axially relative to the caster 31, the distance extending approximately equal to the thickness of the housing 2, i.e., the distance between the front and rear panels 6, 5. The platform 33 has a free edge buckle, and a ball 37 is attached to the free edge 35 on the side of the lower surface 36 of the platform 33 and opposite the upper surface 34, wherein the ball 37 is made of a plastic material coated with an elastomer. The ball 37 is thereby formed - a towable suitcase ^ supports rolling, as shown in Figure 1. On the other side of the free edge 35, the platform 33 extends into a bracket. The bracket 38 is bent to be nearly perpendicular to the platform 33. Although the joint between the bracket 38 and the flat plate 3 is circular like a belt of an annular section. The bottom ί 3 〇 is laterally restricted by the two partitions 39, 40 which extend the k σ 33 and the bracket 38 and engage them. In addition to the belt connecting the above elements, the platform 33, the bracket 3 plates 39 extend perpendicularly to each other. ‘, and

1314046 12993PIF

More specifically, each of the partitions 39, 40 has a bevel shape and has an extension angle of about 90 degrees. The recessed portion is turned toward the outer side of the base 3'' to form a caster passage, and the caster passage is at the platform 33 and the bracket 38. A sleeve 41 is provided adjacent the joint between the joints. The sleeve 41 projects toward the outside of the base 30 and is fitted with freely rotatable casters 31, 32. The housing 2 is thereby formed into a disk shape so that the housing 2 can be fixed during assembly of the towable suitcase 1. The base 30 further includes a retractable arm 42 that is secured to the sheath 43 of the base 30 and that extends a cantilever relative to the base in the bracket 38. More specifically, the sheath 43 in the form of a hollow tube protrudes from the bracket 38 at a distance equal to the partitions 39, 40, substantially perpendicular to the platform 33. The struts 44 are like a stick that slides within the sheath 43. The struts include an upper end that forms the shape of the annular handle 45 for the user to hold the towed suitcase. In addition, the two legs 46, 47 protrude from the lateral side of the base 3〇 in the extension of the bracket 38 (ie, parallel to the sheath 43). The receiving body 2 can be fixed by the legs 46, 47, as will be described later. . The box frame 3 usually has the form of a trolley, and by means of the force applied to the handlebar, the box frame 3 is tilted relative to the axis of the casters 31, 32, and then the entire suitcase is towed, and the drawing and towing are quite large. The weight (that is, when the container 2 is fully loaded). Fig. 2 is a further detailed description of the box frame 3. As shown, the frame 3 includes a bottom 12 made of injection molded plastic material.

The I314〇4Lif disk 48, the chassis 48 forms a platform, a bracket 38 and a portion of the partitions 39, 4, the sleeve 43 and the legs 46, 47. According to a preferred embodiment, the chassis 48 is a single set of chassis, and the structure carrying the carrying case thus exhibits an inverted T shape (as shown in Figure 1). In addition to the good rigidity of the towable suitcase 1, it is also relatively easy to manufacture. The chassis 48 is provided with parallel rigid ribs 49 that protrude from the inner surface of the bracket 38 and extend at the junction with the platform to make the chassis 48 stronger, and the box frame 3 is thus more robust. Various components are formed on the chassis 48, including: a d-shaped flange 50, 51 laterally inserted into the base 3 to complete the partitions 39, 40 and the legs 46, 47; a hollow ball 52 having a groove shape The push frame 53 of the bracket 38 protruding from the chassis 48 is engaged such that the ball 52 and the push frame 53 together form a sheath surrounding the strut 44; a square block 54 located at the joint of the platform 33 and the bracket 38 The lower end includes an elastic retainer 55, a resilient retainer 55 and a finger 56 projecting at the lower end of the strut 44 to maintain the strut 44 in a retracted state as long as the pulling force applied to the handlebar 45 does not exceed a predetermined value. Just fine. An L-shaped central cymbal 57 covers the push frame 53, wherein the rear portion of the central cover 57 is fitted with the cart 53 to complete the sheath 43; and the rear sides of the two L-shaped small cross covers 58, 59 engage the legs 46, 47. Each of the casters 31, 32 includes a journal 6 安装 mounted on the bearing, and is seated in a sleeve 41 projecting from the corresponding partition 39, 4 , to form a rotating shaft of the caster 3. 13 1314046 12993PIF ί The ball 37 is fixed (by locking) to the lower surface 36 of the platform 33 along with its free edge 35 to form a support slide for the frame 3. The housing 2 includes a lower surface 64' lower surface 64, a base 3, and a disk-shaped complementary shape, wherein the lower surface 64 is stacked on the frame 3 but at the same time the housing 2 is assembled with the frame 3. As shown in Fig. 1, the rear panel 5 and the side panels 8, 9 include slits 65, 66 complementary to the partitions 39, 4, and the slits 65, 66 are stacked on the partitions 39, 40 during assembly. Moreover, the bottom 22 of the valley body 2 presents a disc shape complementary to the base and includes a rear wall 67 and two side walls 68,69. The rear wall 67 extends vertically to the lower wall 22' and abuts against the rear panel 5 to enhance its strength. The two side walls μ, 69 project outwardly with their recesses facing outward and against the partitions 39, 40 via the side panels 8, 9. The bottom portion 22 thereby not only makes the container itself stronger, but also makes the connection relationship with the frame 3 stronger. The rear panel 5 is further provided with a plurality of holes 72 drilled near the side edges of the rear panel 5 and &lt; a plurality of holes 73 in the vicinity of the lower edge of the rear panel 5. The hole 72 allows the screw 63 to be spring-locked to the leg 46, 47, and the hole 73 allows the screw 63 to pass through and lock to the bracket 38 of the base 3. The housing 2 and the frame 3 are assembled in the following manner. The front and rear panels 6, 5, the side walls 7, and the bottom portion 22 are first assembled to form the receiving body 2. The housing 2 is then mounted on the frame 3 that has been assembled first. At the time of installation, the lower surface 64 of the housing 2 (by clamping force) is stacked on the base 30 (or a slight distance from the base 30) to form a disk-shaped body, and the bottom portion 22 of the receiving body 2

1314046 12993PIF

Stacked on the platform 33, the rear plate 5 is locked to the bracket 38, and the sheath 43 is received in the recess 70. Then, the holder 63 is fixed to the frame 3 by the screws 63 through the holes 71, 72, 73 of the rear panel 5, respectively, to the sheath 43, the leg 46' 47 and the bracket 38. Additional screws may be provided to secure the bottom portion 22 to the platform 33 as necessary. The platform 33 thus covers almost the entire bottom 22, preventing the towable suitcase 1 from sinking. The assembly is very simple, however it is determined that the towable suitcase 1 can stand very stable. It can be seen that the frame 3 extends entirely beyond the receiving body 2, although the sheath 43 slightly covers the internal space of the containing body 2 via the recess 70. However, the slightly covered portion is not equal to the space occupied by the retractable handle that is usually mounted in the housing to tow the suitcase. According to the specific embodiment of Fig. 4 (wherein the interior of the housing 2 is indicated by the arrow F), the front of the sheath 43 (the side facing the rear panel 5) projects outwardly, but the opposite rear surface is substantially coplanar or only It is slightly convex. Once the body 2 is placed on the frame 3, the sheath 43 thus fills or slightly passes over the surface of the rear panel 5 to facilitate the compactness and aesthetics of the suitcase. In order to increase the volume available in the housing 2, it is also possible to add an outwardly facing branch to the sheath 43 while at the same time making the depth of the recess 70 shallow or even removing the recess (not shown). Overall, the towable suitcase 1 achieves the best balance between weight, size, capacity and stiffness.

1314046 12993PIF

Since the frame 3 itself has the rigidity required for towing, it is not necessary to provide any special reinforcing elements of the container 2, for example, any reinforcement at the seam, the bond or the weld, which is advantageous for the towable suitcase.成本 Cost and weight control. In addition, the struts 44 are movable to move between a retracted position and a slidable position. In the retracted position, the struts 44 are received within the sheath 43 and the handle 45 is passed through the sheath 43 and received in a complementary receiving member 74 formed in the rear panel 5 and covering the recess 70. The handle 45 is thus overfilled or simply passed over the surface of the rear panel 5 (see Figure 5). In the deployed position, at least a portion of the struts 44 are located outside the sheath 43 and the handlebars 45 cover the accommodating body 2 to enhance the leverage of the user when pulling the towable suitcase, and thus the user is towed The box 1 can maintain the correct standing position. As shown in Fig. 1, the housing 2 is substantially elliptical because the front and rear panels 6, 5 are slightly convex. The sheath 43 is said to be slightly curved to match the shape of the rear panel 5. This is in the expansion position

Advantageously, the handlebar 45 is substantially perpendicular to the inertia center of the suitcase 1, thereby reducing the force required to tow the suitcase. 1 WT Of course, it should be understood that the present invention is not limited to the specific embodiments described above. In particular, the collapsible arm 44 should be comprised of two parallel slide bars that are inserted into and parked on a crossbar mounted to the base 3〇-connecting the free end of the slide bar. It has been revealed that the above-mentioned month has been disclosed in a better example.
