DETAILED DESCRIPTION OF THE INVENTION

[0009] Exemplary embodiments of the present invention are disclosed below. The configurations of the embodiments described below, as well as the actions and results (effects) obtained from the configurations, are merely examples. The present invention can also be realized by configurations other than those disclosed in the following embodiments. Furthermore, according to the present invention, it is possible to obtain at least one of the various effects (including derivative effects) obtained by the following configurations.

[0010] The following exemplary embodiments include similar configurations, and each embodiment provides similar effects based on those similar configurations. Note that, in the following, similar components are given the same reference numerals, and redundant explanations may be omitted.

[0011] In this specification, ordinal numbers are used for convenience to distinguish between directions, parts, members, etc., and do not indicate priority or order.

[0012] In each figure, each direction in the item storage shelf is indicated by an arrow. The X, Y, and Z directions intersect and are perpendicular to each other. The Z direction is approximately along the vertical direction, with the Z direction pointing upward and the opposite direction of the Z direction pointing downward. The X and Y directions are approximately along the horizontal direction.

[0013] The article storage shelf stopper is also simply referred to as a stopper.

[0014] [First embodiment] FIG. 1 is a perspective view of the stopper 200R (200) of the first embodiment, FIG. 2 is a plan view of the stopper 200R, FIG. 3 is a side view of the stopper 200R, and FIG. 4 is a front view of the stopper 200R.

[0015] 1 to 4 all show the state in which stopper 200R is attached to an article storage shelf. The article storage shelf has a framework structure, and in this embodiment, the framework structure is made up of components 110R and 120. Stopper 200R is attached near the connection between member 110R and member 120, near end 110a of member 110R.

[0016] The members 110R and 120 are hollow rectangular pieces (square pipes) made of a metal material such as stainless steel or an aluminum alloy.

[0017] The member 110R extends in the X direction and has an end 110a in the X direction. The X direction is an example of a first direction, and the member 110R is an example of a first member.

[0018] The member 110R has an upper surface 111, a lower surface 112, and side surfaces 113 and 114. The upper surface 111 faces in the Z direction, i.e., upward, intersects with and is approximately perpendicular to the Z direction, and extends in the X direction with an approximately constant width in the Y direction. The lower surface 112 faces in the opposite direction to the Z direction, i.e., downward, intersects with and is approximately perpendicular to the Z direction, and extends in the X direction with an approximately constant width in the Y direction. The side surface 113 faces in the Y direction, intersects with and is approximately perpendicular to the Y direction, and extends in the X direction with an approximately constant width in the Z direction. The side surface 114 faces in the opposite direction to the Y direction, intersects with and is approximately perpendicular to the Y direction, and extends in the X direction with an approximately constant width in the Z direction. The upper surface 111 and the lower surface 112 are approximately parallel, and the side surfaces 113 and 114 are approximately parallel.

[0019] The member 120 extends in the Y direction from a position away from the end 110a of the member 110R in the opposite direction to the X direction. The Y direction is an example of a second direction, and the member 120 is an example of a second member.

[0020] The member 120 has an upper surface 121, a lower surface 122, and side surfaces 123 and 124. The upper surface 121 faces upward, intersects the Z direction and is generally perpendicular to it, and extends in the Y direction with a generally constant width in the X direction. The lower surface 122 faces downward, intersects the Z direction and is generally perpendicular to it, and extends in the Y direction with a generally constant width in the X direction. The side surface 123 faces the X direction, intersects the X direction and is generally perpendicular to it, and extends in the Y direction with a generally constant width in the Z direction. The side surface 124 faces in the opposite direction to the X direction, intersects the X direction and is generally perpendicular to it, and extends in the Y direction with a generally constant width in the Z direction. The upper surface 121 and the lower surface 122 are generally parallel, and the side surfaces 123 and 124 are generally parallel.

[0021] Furthermore, the upper surface 111 of the member 110R and the upper surface 121 of the member 120 are substantially flush with each other, and the lower surface 112 of the member 110R and the lower surface 122 of the member 120 are substantially flush with each other.

[0022] The stopper 200R is attached to the article storage shelf and prevents an article (not shown) placed on the member 110R or the member 120 from moving in a direction intersecting the vertical direction.

[0023] The stopper 200R includes an upper wall 201, a lower wall 202, and a side wall 203.

[0024] The upper wall 201 extends in a direction intersecting the Z direction. The upper wall 201 is placed on the upper surface 111 of the member 120 and the upper surface 121 of the member 120. The upper wall 201 is an example of a first upper wall.

[0025] The lower wall 202 is spaced downward from the upper wall 201 and extends in a direction intersecting the Z direction. The lower wall 202 faces the lower surface 112 of the member 110R with a gap g (see FIG. 3) therebetween. The upper wall 201 and the lower wall 202 are approximately parallel to each other.

[0026] The side wall 203 extends substantially along the Z direction between the upper wall 201 and the lower wall 202. In this embodiment, the side wall 203 is located rearward in the Y direction from the side surface 114 of the member 110R, extends along the side surface 114, and widens to intersect with the Y direction.

[0027] The bottom wall 202 protrudes in the Y direction from a position of the lower end of the side wall 203 that is close to the end 110a of the member 110R with a substantially constant width in the X direction.

[0028] In this configuration, the upper surface 111 of the member 110R and the upper surface 121 of the member 120 limit the downward movement of the upper wall 201, that is, the stopper 200R.

[0029] Additionally, the lower surface 112 of the member 110R limits the upward movement of the lower wall 202, ie, the stopper 200R.

[0030] Furthermore, the movement of the side wall 203, i.e., the stopper 200R, in the Y direction is restricted by the side surface 114 of the member 110R. The side wall 203 is an example of a second restricting portion R2, and the side surface 114 is an example of a second portion Pa2. The side wall 203 protruding downward from the upper wall 201 is also an example of a second protruding portion Pr2, and the lower wall 202 protruding in the Y direction from the side wall 203 is also an example of a third protruding portion Pr3.

[0031] Furthermore, the stopper 200R includes a first protruding portion Pr1, a first limiting portion R1, and a third limiting portion R3. These first protruding portion Pr1, first limiting portion R1, and third limiting portion R3, together with the side wall 203 (second limiting portion R2), prevent the stopper 200R from moving in a direction intersecting with the vertical direction from the attachment position on the item storage shelf shown in FIGS.

[0032] The stopper 200R has, as a first protrusion Pr1, a protrusion 204 that protrudes downward from the end of the upper wall 201 facing away from the X direction. The protrusion 204 is located rearward in the X direction relative to a side surface 124 of the member 120, and extends in the Y direction along the side surface 124 at a substantially constant height in the Z direction. The side surface 124 (member 120) limits the movement of the protrusion 204 as the first protrusion Pr1, i.e., the stopper 200R, in the X direction.

[0033] The stopper 200R has a protrusion 205 that protrudes downward from the upper wall 201 along the side surface 123 of the member 120 as a first limiting portion R1. The protrusion 205 is located forward in the X direction relative to the side surface 123 and extends in the Y direction along the side surface 123 at a substantially constant height in the Z direction. The side surface 123 (member 120) limits the movement of the protrusion 205 as the first limiting portion R1, i.e., the stopper 200R, in the direction opposite to the X direction. The side surface 123 of the member 120 facing the protrusion 205 is an example of a first portion Pa1. The protrusion 205 is also an example of a second protrusion Pr2.

[0034] The stopper 200R has, as a third limiting portion R3, a protruding portion 206 that protrudes upward from the bottom wall 202 along the side surface 113 of the member 110R. The protruding portion 206 is located forward in the Y direction relative to the side surface 113 and extends in the X direction along the side surface 113 at a substantially constant height in the Z direction. The side surface 113 (member 110R) limits the movement of the protruding portion 206 as the third limiting portion R3, i.e., the movement of the stopper 200R in the direction opposite to the Y direction. The side surface 113 of the member 110R facing the protruding portion 206 is an example of a third region Pa3. The protruding portion 206 is also an example of a third protruding portion Pr3.

[0035] In this embodiment, the end 204b of the protrusion 204 on the opposite side in the Y direction also functions as the third limiting portion R3. That is, the side surface 113 of the member 110R limits the movement of the end 204b as the third limiting portion R3, i.e., the stopper 200R, in the opposite direction in the Y direction.

[0036] The stopper 200R is provided with a protrusion 207 as a stopper portion that restricts movement of an article in a direction intersecting the Z direction. The protrusion 207 protrudes upward from the X-direction end of the upper wall 201. The protrusion 207 extends in the Y direction at a substantially constant height in the Z direction. In this embodiment, the protrusion 207 can function as a barrier that restricts movement of an article in the X direction. The protrusion 207 also contributes to improving the rigidity of the stopper 200R. As shown in FIGS. 2 to 4, triangular ribs 207a that protrude toward the inside of the bend are provided at multiple intervals at the corner that is the boundary between the upper wall 201 and the protrusion 207. This configuration improves the rigidity of the protrusion 207.

[0037] The stopper 200R having the above-described configuration can be easily attached to an article storage shelf. Fig. 5 is a side view showing the stopper 200R in the process of being attached to the article storage shelf.

[0038] First, the worker or the robot moves the stopper 200R in the opposite direction to the X direction so that the member 110R is surrounded by the upper wall 201, the lower wall 202, and the side wall 203 (S1).

[0039] Next, the worker or robot tilts the stopper 200R clockwise in Fig. 5 relative to the orientation in which the upper wall 201 is substantially horizontal, so that the lower end 204a of the protrusion 204 is positioned above the upper surface 121 of the member 120, the upper wall 201 is positioned above the upper surface 111 of the member 110R and the upper surface 121 of the member 120, and the lower wall 202 is positioned below the lower surface 112 of the member 110R (S2). As a result, the stopper 200R assumes the tilted orientation shown in Fig. 5.

[0040] Next, the worker or the robot slides the stopper 200R in the direction opposite to the X direction in the inclined posture shown in FIG. 5 (S3).

[0041] Next, the worker or robot releases the grip when the lower end 204a of the protrusion 204 is positioned rearward of the member 120 in the X direction. This causes the stopper 200R to rotate counterclockwise due to gravity, and the upper wall 201 becomes approximately horizontal, thereby achieving the attached state of the stopper 200R shown in Figures 1 to 4. Alternatively, the worker or robot may rotate the stopper 200R counterclockwise in Figure 5 from a state in which the lower end 204a is positioned rearward of the member 120 in the X direction, so that the upper wall 201 becomes approximately horizontal (S4).

[0042] In a configuration that takes into consideration the sliding of stopper 200R in the opposite direction in the X direction when in the inclined position in S3 and manufacturing variations in the item storage shelf and stopper 200R, a gap g (see FIG. 3) is generated between the lower surface 112 of member 110R and the lower wall 202 in the attached state. Note that the inclination of stopper 200R in S2 and S3 is not essential, and stopper 200R may be configured to be slidable in the opposite direction in the X direction when upper wall 201 is in a substantially horizontal position. However, if stopper 200R is configured so that it cannot slide in the opposite direction in the X direction when upper wall 201 is in a substantially horizontal position, and so that upper wall 201 is slidable in the opposite direction in the X direction when in the inclined position as shown in FIG. 3, gap g can be at least partially reduced, and stopper 200R becomes less likely to rattle.

[0043] As described above, the stopper 200R of this embodiment can be attached to an item storage shelf simply by moving it, and no bolting or other process is required for attachment. Furthermore, the stopper 200R does not utilize partial elastic deformation, such as a snap fit, for attachment. Therefore, the stopper 200R can be relatively easily manufactured by bending a single plate-like member having a thickness sufficient to ensure the required rigidity, without providing any thin portions. In other words, the stopper 200R can be manufactured from a bent plate-like member. Integration of multiple members by welding, etc., is also essentially unnecessary.

[0044] As described above, according to this embodiment, it is possible to obtain a new and improved stopper 200R for an article storage shelf, which has a simpler configuration and can be attached more easily.

[0045] [Second embodiment] 6 is a perspective view of a stopper 200RA (200) of the second embodiment. The stopper 200RA of this embodiment has the same configuration as the stopper 200R of the first embodiment, and can be attached to an article storage shelf in the same manner as the stopper 200R of the first embodiment.

[0046] However, the stopper 200RA of this embodiment includes, as the first limiting portion R1, a protruding portion 208 protruding in the Y direction from the X-direction end of the side wall 203, instead of the protruding portion 205 (see FIG. 1). The protruding portion 208 is located forward in the X direction relative to the X-direction end 110a of the member 110R, and extends in the Z direction along the end 110a at a substantially constant height in the Y direction. In this case, the end 110a (member 110R) limits the movement of the protruding portion 208 as the first limiting portion R1, i.e., the stopper 200RA, in the direction opposite the X direction. The end 110a is an example of the first portion Pa1, and the protruding portion 208 is an example of the third protruding portion Pr3. This embodiment also achieves the same effects as the first embodiment. Furthermore, this embodiment eliminates the need for the protruding portion 205, thereby enabling the size of the stopper 200RA in the Y direction to be reduced accordingly.

[0047] [Third embodiment] 7 is a perspective view of the stopper 200RB (200) of the third embodiment. The stopper 200RB of this embodiment has the same configuration as the stopper 200R of the first embodiment, and can be attached to an article storage shelf in the same manner as the stopper 200R of the first embodiment.

[0048] However, stopper 200RB of this embodiment has, as first limiting portion R1, end portion 206a of protrusion 206 on the opposite side in the X direction, instead of protrusion 205 (see FIG. 1). Protrusion 206 extends in the X direction at a substantially constant height in the Z direction, and end portion 206a contacts or faces side surface 123 of member 120 with a slight gap therebetween. In this case, end portion 110a (member 110R) limits movement of end portion 206a (protrusion 206) as first limiting portion R1, i.e., stopper 200RB, in the opposite direction in the X direction. This embodiment also provides effects similar to those of the other embodiments described above.

[0049] [Fourth embodiment] 8 is a plan view of a stopper 200RC (200) of the fourth embodiment. The stopper 200RC of this embodiment has the same configuration as the stopper 200R of the first embodiment, and can be attached to an article storage shelf in the same manner as the stopper 200R of the first embodiment.

[0050] However, the stopper 200RC of this embodiment includes a protrusion 209 protruding downward from the upper wall 201 as the first limiting portion R1, instead of the protrusion 205 (see FIG. 1). The protrusion 209 is formed by bending downward and raising the inner region of a substantially U-shaped notch 201a formed in the upper wall 201. The protrusion 209 is located forward in the X direction relative to the side surface 123 of the member 120, and extends in the Y direction along the side surface 123 at a substantially constant height in the Z direction. The side surface 123 (member 120) limits the movement of the protrusion 209 as the first limiting portion R1, i.e., the stopper 200RC, in the direction opposite the X direction. The protrusion 209 is an example of a second protrusion Pr2. This embodiment also provides the same effects as the other embodiments described above.

[0051] [Fifth embodiment] 9 is a plan view of a stopper 200RD (200) of the fifth embodiment. The stopper 200RD of this embodiment has the same configuration as the stopper 200RC of the fourth embodiment, and can be attached to an article storage shelf in the same manner as the stopper 200RC of the fourth embodiment.

[0052] However, the stopper 200RD of this embodiment includes a protrusion 210 that protrudes downward from the upper wall 201 as the third limiting portion R3, instead of the protrusion 206. The protrusion 210 is formed by bending downward and raising the inner region of a substantially U-shaped notch 201b formed in the upper wall 201. The protrusion 210 is located forward in the Y direction relative to the side surface 113 of the member 110R and extends in the X direction along the side surface 113 at a substantially constant height in the Z direction. The side surface 113 (member 110R) limits the movement of the protrusion 210 as the third limiting portion R3, i.e., the stopper 200RD, in the direction opposite the Y direction. The protrusion 210 is an example of the second protrusion Pr2. This embodiment also provides the same effects as the other embodiments described above.

[0053] [Sixth embodiment] 10 is a plan view of a stopper 200E (200) of the sixth embodiment. The stopper 200E of the present embodiment is attached to the item storage shelf using, in addition to the members 110R and 120, members 110L and 130 as components of the item storage shelf.

[0054] The member 110L has substantially the same configuration as the member 110R. The member 110L is spaced apart from the member 110R in the Y direction, aligned with the member 110R at a distance in the Y direction, and extends substantially parallel to the member 110R in the X direction. The member 110L has an end 110a in the X direction. The end 110a is substantially aligned with the end 110a of the member 110R in the Y direction. The member 110L is an example of a third member. The end 110a of the member 110L is an example of a second end.

[0055] The member 120 extends in the Y direction between the member 110R and the member 110L and is connected to both the member 110R and the member 110L. That is, the member 120 extends in the opposite direction in the Y direction from the member 110L.

[0056] Member 130 is located between members 110R and 110L and is located forward of member 120 in the X direction. Member 130 extends in the Z direction. Member 130 is a hollow rectangular piece (square pipe) made of a metal material such as stainless steel or an aluminum alloy. Member 130 also has a side surface 130a. Side surface 130a faces the X direction and extends in the Z direction with a substantially constant width in the Y direction. Member 130 is an example of a fourth member. Side surface 130a faces the X direction and may also be referred to as a front surface.

[0057] The article storage shelf is provided with a member 110C between the members 110L and 110R, extending approximately parallel to these members 110L and 110R, but in this embodiment, this member 110C is not related to the attachment of the stopper 200E.

[0058] Stopper 200E has a portion 200Er having an upper wall 201 placed on member 110R and member 120, a portion 200El having an upper wall 201 placed on member 110L and member 120, and a connecting portion 211 connecting the upper walls 201 of portions 200Er and 200El. The upper wall 201 of portion 200Er is an example of a first upper wall, and the upper wall 201 of portion 200El is an example of a second upper wall.

[0059] In this embodiment, the two upper walls 201 and the connecting portion 211 are configured as a single flat plate. However, this is not limiting, and the connecting portion 211 may be provided with a step, a rib, or the like. Furthermore, the protruding portion 207 may extend from the portion 200Er to the portion 200El via the connecting portion 211. By providing the connecting portion 211 with a step, a rib, the protruding portion 207, or the like, the rigidity of the stopper 200E can be improved.

[0060] The portions 200Er and 200El have mirror-image structures. The portions 200Er and 200El each have an upper wall 201, a lower wall 202, a side wall 203, and protrusions 204 and 207. In the attached state, the shapes and arrangements of the portions 200Er and 200El, i.e., the shapes and arrangements of the upper wall 201, the lower wall 202, the side wall 203, and the protrusions 204 and 207 of the portions 200Er and 200El, are symmetrical with respect to an imaginary center plane C that is perpendicular to the Y direction at a midpoint between the portions 200Er and 200El and extends in the Z and X directions.

[0061] In this configuration, the portion 200Er and the portion 200El each have an upper wall 201 and a lower wall 202. The lower wall 202 of the portion 200Er faces the lower surface 112 of the member 110R with a gap therebetween, and the lower wall 202 of the portion 200El faces the lower surface 112 of the member 110L with a gap therebetween. The upper wall 201 limits downward movement of the stopper 200E. The lower wall 202 limits upward movement of the stopper 200E.

[0062] The side wall 203 of the portion 200Er faces the side surface 114 of the member 110R facing in the opposite direction to the Y direction, and functions as a second limiting portion R2. The side surface 114 of the member 110R is an example of a second portion Pa2. On the other hand, the side wall 203 of the portion 200El faces the side surface 113 of the member 110L facing in the Y direction, and functions as a third limiting portion R3. The side surface 113 of the member 110L is an example of a third portion Pa3. In this way, since the two side walls 203 function as the second limiting portion R2 and the third limiting portion R3, in this embodiment, the protrusion 206 (see FIG. 1) and the protrusion 210 (see FIG. 9) provided in the other embodiments described above are not necessary.

[0063] The portions 200Er and 200El each have a protrusion 204 as a first protrusion Pr1 and a protrusion 207 as a stopper portion. The protrusions 207 limit the movement of the article in the X direction at the front and rear of the member 130 in the Y direction.

[0064] The connecting portion 211 passes in front of the member 130 in the X direction and connects the member 110R and the member 110L. An end portion 211a of the connecting portion 211 on the opposite side in the X direction faces the side surface 130a of the member 130 and functions as a first limiting portion R1. That is, the side surface 130a (member 130) limits the movement of the end portion 211a as the first limiting portion R1, i.e., the stopper 200E, in the opposite direction in the X direction. The side surface 130a is an example of a first portion.

[0065] The stopper 200E of this embodiment can be attached to an item storage shelf in the same manner as the stopper 200R of the first embodiment. As described above, the connection portion 211 is located forward in the X direction relative to the member 130, in other words, it bypasses the front of the member 130. Therefore, the connection portion 211 does not become an obstacle when attaching the stopper 200E to an item storage shelf by sliding it in the opposite direction to the X direction.

[0066] The present embodiment described above also provides the same effects as the other embodiments described above. Furthermore, according to the present embodiment, the stoppers 200 can be attached to the two locations on the item storage shelf where the stoppers 200 are required in a single attachment operation, which has the advantage of shortening the time required for the attachment operation.

[0067] From the viewpoint of stabilizing the posture of the stopper 200E, it is preferable that the lower wall 202, the protruding portion 204 (first protruding portion Pr1), and the side wall 203 (second limiting portion R2 or third limiting portion R3) are provided on both the portion 200Er and the portion 200El.

[0068] The structures of the portions 200Er and 200El are not limited to those of this embodiment and may be different from those of the stopper 200 of the other embodiments. The structures of the portions 200Er and 200El do not necessarily have a mirror image relationship. The end 211a of the connecting portion 211 does not necessarily function as the first limiting portion R1. Either the portion 200Er or the portion 200El may have the first limiting portion R1, such as the protrusion 205 (see FIG. 1), the protrusion 208 (see FIG. 6), the end 206a (see FIG. 7), or the protrusion 209 (see FIG. 8) of the other embodiments. In this case, from the viewpoint of stabilizing the posture of the stopper 200E, it is preferable that the first limiting portion R1 be provided on both the portion 200Er and the portion 200El. The connecting portion 211 may have a protrusion or recess facing the member 130 and functioning as the second limiting portion R2 or the third limiting portion R3. In this case, the member 130 is provided with the second portion Pa2 or the third portion Pa3.

[0069] While the embodiments of the present invention have been described above, they are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the spirit of the invention. Furthermore, the specifications of each configuration, shape, and the like (structure, type, direction, model, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately modified and implemented.

[0070] For example, the storage shelf may have a component other than the components disclosed in the above embodiment, and the other component may have a first portion, a second portion, or a third portion. Furthermore, each component may be provided with an appropriate attachment, or may be provided with a slit, a hole, or the like.

[0071] Furthermore, the arrangement and shape of the first upper wall, second upper wall, and lower wall can be changed in various ways.

[0072] Furthermore, the side wall, the first protrusion, the second protrusion, and the third protrusion can each be realized in various arrangements and shapes, and can function as at least one of the first limiting portion, the second limiting portion, and the third limiting portion.

[0073] For example, the side wall may extend along the side surface of the first member from which the second member protrudes and function as the third limiting portion. In this case, the side wall may further extend along the first member, and the end of the side wall facing the first member may function as the first limiting portion.

[0074] The stopper portion may also suppress movement of the article in a direction that intersects with the vertical direction and is different from the first direction. [Explanation of symbols]
