Description

[Technical Field]

[0001] The present invention relates to a storage case. [Background technology]

[0002] Storage cases for storing household clothing and other items have been known for some time. For example, the storage case disclosed in Patent Document 1 is composed of a drawer for storing items such as clothing and a case body that stores the drawer. The drawer is designed to slide along a rail projection on the bottom surface of the case body. However, if the storage case is dropped during transportation and receives an impact while the drawer is stored in the case body, the drawer may collide with the case body, causing damage to the drawer. In addition, stress caused by the impact may be concentrated around the contact point between the rail projection of the case body and the drawer, causing damage to the drawer. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4038461 Summary of the Invention [Problem to be solved by the invention]

[0004] In view of the above problems, the present invention provides a storage case that prevents damage to the drawers due to dropping or the like. [Means for solving the problem]

[0005] In order to solve the above problems, the present invention Claims 1 and 2The storage case according to the present invention is a storage case comprising a drawer and a case body, wherein a rail protrusion for sliding the drawer is provided on the upper surface of the bottom of the case body, and a receiving portion that faces the rail protrusion when the drawer is stored in the case body is provided on the lower surface of the bottom of the drawer, and a protrusion for preventing breakage is formed on the receiving portion.

[0006] According to the above feature, the receiving portion is formed with a breakage prevention protrusion, which increases the strength of the receiving portion as a whole. Therefore, even if stress is concentrated on the receiving portion, damage to the receiving portion can be prevented, and as a result, damage to the drawer can be effectively prevented even if the storage case is dropped.

[0007] Furthermore, the claims of the present invention 1 The storage case according to the present invention is characterized in that the radius of curvature of the connecting portion between the lower surface of the bottom of the drawer and the receiving portion is larger than that of other portions.

[0008] According to the above features, by connecting the receiving portion to the bottom portion with a gently curved surface having a large radius of curvature, the stress caused by the impact when the storage case is dropped is not concentrated locally at the connection portion, and damage to the drawer can be more effectively prevented.

[0009] Furthermore, the claims of the present invention 2 The storage case according to the present invention is characterized in that a recess is provided on the upper surface of the bottom of the drawer at the location where the breakage prevention projection is formed.

[0010] According to the above feature, when the drawer is injection molded using a mold, the recess can prevent deformation around the breakage prevention protrusion during molding. [Effects of the Invention]

[0011] The storage case of the present invention can prevent the drawers from being damaged by dropping or the like. [Brief explanation of the drawings]

[0013] 100 drawers 110 Bottom 111 Bottom surface 180 Receiving part 190 Damage prevention protrusion 200 case body 210 Bottom 270 Rail protrusion 300 storage case DETAILED DESCRIPTION OF THE INVENTION

[0014] The following describes an embodiment of the present invention with reference to the drawings. In this specification, "upper" refers to the direction facing upward in the vertical direction when the drawer is placed on a horizontal surface with the opening facing up, and "lower" refers to the direction facing downward in the vertical direction. Furthermore, "front" refers to the side of the drawer where the handle is provided, and "rear" refers to the side opposite the front.

[0015] Fig. 1 shows a storage case 300 according to the present invention, and Fig. 2 shows a case body 200 of the storage case 300. Fig. 1 is an overall perspective view of the storage case 300 with the drawer 100 pulled out from the case body 200, Fig. 2(a) is a cross-sectional view taken along line A-A in Fig. 1, and Fig. 2(b) is an end view taken along line A'-A'.

[0016] As shown in FIG. 1, the storage case 300 includes a drawer 100 for storing items such as clothes, and a case body 200 that slidably accommodates the drawer 100. As shown in FIGS. 1 and 2, the case body 200 is made entirely of synthetic resin and has a generally rectangular parallelepiped shape, including a bottom 210, side sections 220 rising from both sides of the bottom 210, a rear section 240, and a top section 230, with an opening 250 at the front. The interior of the case body 200 defines a storage space 260 that communicates with the opening 250, and the drawer 100 can be stored in the storage space 260 from the opening 250. To facilitate storing the drawer 100 in the case body 200, the size of the portion of the drawer 100 that is stored in the case body 200 in the circumferential direction is smaller than the opening 250 of the case body 200. Furthermore, when the drawer 100 is stored in the case body 200, the drawer 100 is configured not to come into contact with the outer surface of the opening frame of the outer periphery 251 of the opening 250.

[0017] Furthermore, a rail protrusion 270 protruding upward is provided on the top surface of the bottom 210 of the case body 200. Specifically, as shown in FIG. 2, the rail protrusion 270 has a generally U-shaped cross section with an upper wall 273, an inner wall 274, and an outer wall 275, and is formed integrally with the bottom 210. A rail guide portion 170 of the drawer 100, which will be described later, can be disposed on the outer wall 275 side of the rail protrusion 270. The rail protrusion 270 extends linearly from a leading end 271 to an end 272, and guides a portion of the drawer 100 so that the drawer 100 slides in the front-to-rear direction. Note that while the rail protrusion 270 is formed integrally with the bottom 210, this is not limiting, and the rail protrusion 270 may be formed separately from the bottom 210 and attached to the bottom 210. Furthermore, the radius of curvature of the outer edge portion of outer periphery 251 of opening 250 is made large, which prevents a user from injuring themselves by hitting their fingers or the like against the outer edge portion of outer periphery 251 of opening 250 when pulling out drawer 100 from opening 250 or storing drawer 100 into opening 250. Furthermore, the radius of curvature of the outer edge portion of outer periphery 231 of top part 230 is made large, so that top part 230 is less likely to be damaged even if the outer edge portion of outer periphery 231 of top part 230 hits another part when storage case 300 is transported or stored.

[0018] Next, the configuration of drawer 100 will be described in detail with reference to Figures 3 to 6. Note that Figure 3 is an overall perspective view of drawer 100, Figure 4 is a bottom view of drawer 100, Figure 5 is a bottom view of drawer 100 with an enlarged view of the area around receiving portion 180, Figure 6(a) is a B-B end view of Figure 5, Figure 6(b) is a C-C end view of Figure 5, and Figure 6(c) is a D-D end view of Figure 5.

[0019] As shown in Figure 3, drawer 100 is made entirely of synthetic resin and has a roughly rectangular parallelepiped shape, with a bottom 110, side sections 120 rising from both sides of bottom section 110, a front section 130, and a rear section 140, with an opening 150 at the top. The interior of drawer 100 forms storage section 160, and is configured so that clothing and other items can be stored in storage section 160 through opening 150. In addition, a handle 131 is provided at the upper end of front section 130, protruding to allow fingers to be hooked.

[0020] 4 and 5, a rail guide portion 170 protruding downward is provided on the underside 111 of the bottom 110 of the drawer 100. The rail guide portion 170 extends linearly from the leading end 171 to the trailing end 172, and is the portion that slides along the rail protrusion 270 of the case main body 200 when the drawer 100 slides in the front-to-rear direction. Therefore, the rail guide portion 170 of the drawer 100 and the rail protrusion 270 of the case main body 200 allow the drawer 100 to slide smoothly in the front-to-rear direction.

[0021] Next, as shown in FIGS. 5 and 6, a receiving portion 180 is provided on the underside 111 of the bottom 110 of the drawer 100, on the side of the tip 171 of the rail guide portion 170. This receiving portion 180 faces the tip 271 of the rail protrusion 270 and is configured to be able to abut against the rail protrusion 270, thereby positioning the drawer 100 in the front-to-rear direction when the drawer 100 is housed in the case body 200. The receiving portion 180 protrudes downward from the underside 111 of the bottom 110 and includes a main body portion 181 facing the tip 271 of the rail protrusion 270 and a connecting portion 182 extending forward from the main body portion 181. The main body portion 181 is connected to the tip 171 of the rail guide portion 170, thereby increasing the rigidity of the receiving portion 180. Furthermore, the connecting portion 182 is connected to the reinforcing rib 132 on the front side 130, thereby increasing the rigidity of the receiving portion 180. The reinforcing rib 132 protrudes downward from the lower surface 111 of the bottom portion 110 and extends linearly along the front portion 130.

[0022] Further, a breakage prevention protrusion 190 is formed on the main body 181 of the receiving portion 180. The breakage prevention protrusion 190 protrudes downward from the lower surface 111 of the bottom 110 and is connected to an opposite surface 184 on the opposite side of an opposing surface 183 that faces the tip 271 of a rail protrusion 270 (described later). Furthermore, the breakage prevention protrusion 190 is not connected to the reinforcing rib 132 but is spaced apart, so that a space 191 exists between the breakage prevention protrusion 190 and the reinforcing rib 132. Note that the receiving portion 180 has a substantially L-shape including the main body 181 and the connecting portion 182, but is not limited thereto, and the receiving portion 180 may have any shape as long as it is configured to face the rail protrusion 270. Furthermore, the breakage prevention protrusion 190 is not connected to the reinforcing rib 132 but is spaced apart therefrom, but is not limited thereto, and the breakage prevention protrusion 190 may be connected to the reinforcing rib 132. When the breakage prevention protrusion 190 is connected to the reinforcing rib 132, the rigidity is increased, but stress is more likely to be transmitted to the reinforcing rib 132, which may result in breakage of the reinforcing rib 132. Furthermore, although one breakage prevention protrusion 190 is provided on the receiving portion 180, this is not limitative, and two or more breakage prevention protrusions 190 may be provided on the receiving portion 180.

[0023] 5, a protruding portion 151 is provided on the outside of the receiving portion 180 on an extension of the bottom portion 110. This protruding portion 151 protrudes to the front side (i.e., toward the front portion 130) and the side side (i.e., toward the side portion 120) of the receiving portion 180, and a reinforcing rib 132 is provided on the front side. Further, a reinforcing rib 152 protruding downward is formed on the side side of the receiving portion 180, and the reinforcing rib 132 and the reinforcing rib 152 are connected to surround the outside of the protruding portion 151. Since the protruding portion 151 protrudes to the outside of the receiving portion 180, it protects the periphery of the receiving portion 180 from the impact when the storage case 300 is dropped.

[0024] 6(a) and 6(b), the radius of curvature R1 of the connection portion 113 between the underside 111 of the bottom portion 110 and the receiving portion 180 is larger than the radius of curvature of other portions, and the receiving portion 180 is connected to the bottom portion 110 by a gently curved surface. By connecting the receiving portion 180 to the bottom portion 110 by a gently curved surface in this manner, stress caused by an impact when the storage case 300 is dropped is not concentrated locally on the connection portion 113, and damage to the drawer 100 can be more effectively prevented. Also, as shown in FIG. 6(a), a straight portion 116 is provided at the boundary between the underside 111 of the bottom portion 110 and the connection portion 113 of the receiving portion 180. Furthermore, an inclined surface 119 is provided at the tip side of the curved surface 118 of the connection portion 113, which has a radius of curvature R1. Therefore, as will be described later, when the tip 271 of the rail protrusion 270 abuts against the receiving portion 180 of the drawer 100, the stress caused by the abutment is effectively dispersed in the direction of the tip of the receiving portion 180 (toward the inclined surface 119), making it difficult for the receiving portion 180 to be damaged. Also, the tip 271 of the rail protrusion 270 is guided from the curved surface 118 along the inclined surface 119, and can escape in the direction of the tip of the receiving portion 180 (toward the inclined surface 119). As a result, the stress caused by the abutment is effectively dispersed in the direction of the tip of the receiving portion 180 (toward the inclined surface 119), making it difficult for the receiving portion 180 to be damaged. The radii of curvature of other portions refer to the radii of curvature of the connecting portions between the portions protruding downward from the lower surface 111 of the bottom 110 and the lower surface 111 around the receiving portion 180, such as the radius of curvature R2 of the connecting portions between the breakage prevention projections 190 and the lower surface 111 of the bottom 110, and the radius of curvature R3 of the connecting portions between the reinforcing ribs 132 and the lower surface 111 of the bottom 110. The radius of curvature R1 around the receiving portion 180 is larger than the radius of curvature R3 around the reinforcing ribs 132 and the radius of curvature R4 around the rail guide portion 170 described below (radius of curvature R1 > radius of curvature R3, radius of curvature R1 > radius of curvature R4).

[0025] As shown in FIGS. 6(a) and 6(b), the thickness of the bottom 110 is thickness T1, and the thickness of the portion adjacent to the receiving portion 180 is thickness T2. Thickness T2 is thicker than thickness T1, and by locally thickening the portion of the bottom 110 where it connects to the receiving portion 180, damage to the base of the receiving portion 180 due to external impact when the storage case 300 is dropped is prevented. As shown in FIG. 6(b), thickness T3 of the bottom 110 where it connects to the breakage prevention protrusion 190 is also thicker than thickness T1, and this prevents damage to the base of the breakage prevention protrusion 190 due to external impact when the storage case 300 is dropped. Furthermore, thickness T4 of the protrusion 151 adjacent to the receiving portion 180 and the breakage prevention protrusion 190 is thicker than thickness T1, and this prevents damage to the protrusion 151 due to external impact when the storage case 300 is dropped. In addition, the thickness T2 of the portion adjacent to the receiving portion 180 and the thickness T3 of the portion connecting to the breakage prevention protrusion 190 may be made the same thickness as the thickness T4 of the protrusion 151 (i.e., thickness T4 = thickness T2 = thickness T3), so that the entire bottom 110 around the receiving portion 180 has a constant thickness T4, which is thicker than the thickness T1 of the bottom 110.

[0026] 6(a) and 6(b), a recess 114 is provided in the upper surface 112 of the bottom 110 at the location where the breakage prevention protrusion 190 is formed. The drawer 100 is injection molded using molds located above and below the drawer 100, and providing the recess 114 prevents deformation around the breakage prevention protrusion 190 during molding. Furthermore, a recess 115 is also provided in the upper surface 112 of the bottom 110 at the location where the receiving portion 180 is formed, so that deformation around the receiving portion 180 during molding can be prevented.

[0027] As shown in FIG. 6(c), the radius of curvature R4 of the connection portion 117 between the rail guide portion 170 and the bottom portion 110 is larger than the radius of curvature of other portions, and the rail guide portion 170 is connected to the bottom portion 110 by a gently curved surface. When the drawer 100 is slid, the rail guide portion 170 abuts and slides against the rail protrusion 270 of the case body 200, and is therefore the portion to which stress is applied when the drawer 100 is slid. Therefore, by connecting the rail guide portion 170 to the bottom portion 110 by a gently curved surface, stress when the drawer 100 is slid does not concentrate locally on the connection portion 117, and damage to the drawer 100 can be more effectively prevented. Similarly, even if an impact is applied when the storage case 300 is dropped, stress does not concentrate locally on the connection portion 117, and damage to the drawer 100 can be more effectively prevented.

[0028] Furthermore, thickness T5 of the portion connecting to rail guide portion 170 is also thicker than thickness T1, preventing damage from occurring near the base of rail guide portion 170 due to stress when drawer 100 slides. Similarly, even if storage case 300 is dropped and an impact is applied, damage from occurring near the base of rail guide portion 170 is prevented.

[0029] Next, the state in which drawer 100 is stored in case main body 200 will be described in detail with reference to Fig. 7. Fig. 7 is a bottom view of drawer 100 stored in case main body 200, and is an enlarged bottom view of the area around receiving portion 180. Rail protrusion 270 of case main body 200 is also shown by virtual lines.

[0030] As shown in FIG. 7 , when the drawer 100 is stored in the case body 200, the tip 271 of the rail protrusion 270 abuts against the main body 181 of the receiving portion 180 of the drawer 100 or is close to the main body 181 of the receiving portion 180. When the storage case 300 is dropped in this state and an impact is applied, the tip 271 of the rail protrusion 270 hits the main body 181 of the receiving portion 180 of the drawer 100 hard, causing stress to concentrate on the receiving portion 180. However, the receiving portion 180 is formed with a breakage prevention protrusion 190, which increases the strength of the receiving portion 180 as a whole. Therefore, even if stress concentrates on the receiving portion 180, damage to the receiving portion 180 can be prevented, and as a result, damage to the drawer 100 can be effectively prevented even if the storage case 300 is dropped.

[0031] Furthermore, one end of receiving portion 180 is connected to tip 171 of rail guide portion 170, and the other end of receiving portion 180 is connected to reinforcing rib 132 via connecting portion 182. Therefore, even if stress is applied to receiving portion 180 when storage case 300 is dropped, receiving portion 180 is unlikely to break because both ends of receiving portion 180 are connected to other portions and reinforced. On the other hand, although the intermediate portion between both ends of receiving portion 180 is reinforced by breakage prevention protrusion 190, breakage prevention protrusion 190 is not connected to other portions (e.g., reinforcing rib 132), and a space 191 exists on the side facing breakage prevention protrusion 190. Therefore, when stress is applied to receiving portion 180 when storage case 300 is dropped, there is room for receiving portion 180 to elastically deform slightly toward space 191, so receiving portion 180 can flexibly absorb and disperse the stress and is unlikely to break.

[0032] The storage case of the present invention is not limited to the above examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments, and these modifications and combinations are also included in the scope of rights.
