DETAILED DESCRIPTION

[0025] The effects of the present invention are shown with reference to the accompanying drawings, and the best mode for carrying out the present invention is briefly described.

[0026] The upper opening pull-out body 2 which is freely pulled out and slidably stored in the drawer storage part of the storage main body 1 can be switched to a locked state in which the pull-out sliding is blocked and cannot be pulled out and a locked released state in which it can be pulled out by the lateral sliding operation of the switching operation part of the locking mechanism 3.

[0027] The locking mechanism 3 is composed of a locking engaging recess 4 and a locking engaging protrusion 5 which engages with the locking recess 4 to prevent the above-mentioned pull-out sliding. The above-mentioned locking engaging recess 4 is arranged on the upper surface of the handle part 6, and the handle part 6 is arranged on the upper part of the front part of the above-mentioned pull-out body 2 in a forward protruding state.

[0028] On the other hand, the locking engaging protrusion 5 is vertically arranged on the transverse sliding portion 7, and the transverse sliding portion 7 is freely slidably arranged in the left and right directions at the front of the storage body 1, and the transverse sliding operation portion 8 for making the transverse sliding portion 7 slide laterally is arranged in the front of the storage body 1 in an exposed state.

[0029] Therefore, the exposed lateral slide operation portion 8 serving as the switching operation portion can be visually recognized at a glance, and since the lateral slide operation portion 8 is configured to be lateral slid, the switching operation can be performed simply and quickly without confusion.

[0030] In addition, the above-mentioned locking engagement recess 4 is composed of a preventing recess 9 and a sliding allowing recess 11. When the lateral sliding operation part 8 is operated to make the above-mentioned locking engagement protrusion 5 slide laterally and engage with the above-mentioned lateral sliding part 7, the preventing recess 9 prevents the above-mentioned pull-out body 2 from sliding and being in the above-mentioned locked state that cannot be pulled out. The sliding allowing recess 11 is continuously arranged with the preventing recess 9, has a length in the front-to-back direction and is open at the rear end. When the locked state is reached, when the lateral sliding operation part 8 is operated to slide laterally to make the above-mentioned locking engagement protrusion 5 slide laterally and engage with the preventing recess 9, the preventing recess 9 does not allow the above-mentioned locking engagement protrusion 5 to move relative to each other in the front-to-back direction of the pulling direction, so the pull-out body 2 is in the locked state that cannot be pulled out.

[0031] On the other hand, in the case of switching to the unlocked state, when the locking engaging protrusion 5 is slid laterally in the opposite direction from the locked state and engages with the sliding allowing recess 11, when the pull-out body 2 is pulled forward, the locking engaging protrusion 5 moves relatively in the sliding allowing recess 11 and disengages from the recess from the recess disengagement opening 10 at the rear end, thereby becoming a locked unlocked state that can be pulled out.

[0032] That is, through the lateral sliding operation of the above-mentioned lateral sliding operation part 8, the locking engaging protrusion 5 moves together with the lateral sliding part 7 in the locking engaging recess 4. When sliding laterally to the position of the blocking recess 9, although the locking engaging protrusion 5 wants to move relatively along the front-to-back direction together with the pull-out body 2, it cannot move relatively because it is engaged with the blocking recess 9. Therefore, the pull-out body 2 cannot be pulled out to become the above-mentioned locked state. When sliding laterally to the position of the sliding allowing recess 11, the locking engaging protrusion 5 can move relatively in the sliding allowing recess 11 along with the movement of the pull-out body 2, and can then relatively detach from the recess from the recess detachment opening 10, so it can be switched to the above-mentioned lock release state in which the pull-out sliding of the pull-out body 2 can be performed.

[0033] Therefore, since it can be switched by a simple lateral sliding operation, and a locking engaging recess 4 is provided on the front part of the storage body 1, which is recessed in the upper surface of the handle portion 6 of the upper front part of the pull-out body 2, and a locking engaging protrusion 5 slidably engaged therewith is provided, the lateral sliding operating portion 8 is easy to operate, and since the lateral sliding operating portion 8 is exposed at the upper front part, it can be immediately visually confirmed and can be operated simply and quickly, resulting in a structure that is easy to manufacture and has excellent mass productivity.

[0034] That is, for example, when stacked and loaded on a vehicle, the locking mechanism 3 can be used to set the storage box to a locked state so that the pull-out body 2 does not accidentally pop out when the vehicle is driving. In addition, when the pull-out body 2 is pulled out to take out the stored items or when the pull-out body 2 is pulled out and carried out of the vehicle, the unlocking operation position can be visually confirmed at a glance, and the operation can be understood without being confused about the operation and the unlocking operation can be quickly performed, thereby achieving a storage box with a simple structure, easy manufacture, excellent mass production and extremely excellent practicality.

[0035] [Example]

[0036] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0037] The storage body 1 may also adopt a structure in which the pull-out body 2 can be freely pulled out in multiple layers and stored up and down, but the storage body 1 of this embodiment adopts a structure in which at least a pull-out opening is provided at the front and a drawer storage part for storing one pull-out body 2 is provided, and the upper plate part 12 of the storage body 1 is configured as a cover part that can be freely loaded and unloaded, and a structure that can be stacked on the upper plate part 12 and the pull-out body 2 is arranged in multiple layers up and down is adopted. In addition, although it is not suitable for stacking, casters can be attached to the bottom.

[0038] Thus, in this embodiment, storage boxes each storing a pull-out body 2 in each storage body 1 are stacked into multiple layers, for example, they are loaded on a vehicle cargo bed, and a connecting mechanism is provided for connecting the storage boxes so as to facilitate loading and unloading, as well as a forward tilt prevention locking mechanism for locking the upper storage body 1 to the lower storage body 1 to prevent the pull-out body 2 from tilting forward or falling forward when being pulled forward.

[0039] Moreover, in this embodiment, for example, the drawer 2 is mounted in a vehicle as described above, and in order to prevent the drawer 2 from accidentally popping out during driving, the locking mechanism 3 that prevents the drawer 2 from sliding out and becoming a locked state in which it cannot be drawn out is provided to be freely locked and unlocked.

[0040] For example, when work tools, work parts, and necessary components are separated and organized and stored in the drawer 2 and taken out during work, the lock can be released and the drawer 2 can be pulled out and taken out, or the drawer 2 can be pulled out together and carried to the work site.

[0041] The locking mechanism 3 of the present embodiment is composed of a locking engaging recess 4 and a locking engaging protrusion 5 which engages with the locking recess 4 to prevent the above-mentioned pull-out sliding. The locking engaging recess 4 is formed on the upper surface of the handle portion 6, and the handle portion 6 is integrally formed on the upper part of the front part of the above-mentioned pull-out body 2 in a forward protruding state. On the other hand, the above-mentioned locking engaging protrusion 5 is vertically arranged on the transverse sliding portion 7, and the transverse sliding portion 7 is freely slidably arranged in the left and right directions at the front part of the above-mentioned storage body 1.

[0042] Specifically, the locking engaging recess 4 of the present embodiment is formed in a recessed state on the upper surface of the handle portion 6 for pulling out that extends forward from the front upper portion of the pull-out body 2, and the locking engaging recess 4 is configured to be L-shaped in a top view, which is composed of the above-mentioned blocking recess 9 which is long in a top view and the sliding allowing recess 11 which is long in a top view and has a recessed disengagement opening 10 at the rear end, and the locking engaging recess 4 is configured to be a groove portion with a bottomed top opening. In addition, the locking engaging recess 4 may be formed in a recessed configuration by forming a through hole in the handle portion 6 without having a bottom.

[0043] To further explain, the following structure is adopted: when the pull-out body 2 is pulled out, the fingers can be hooked from the bottom and pulled out, and the handle part 6 on one side of the handle part used for holding when the pull-out body 2 is completely pulled out from the storage body 1 is integrally molded during the resin molding of the pull-out body 2.

[0044] That is, by designing the mold of the drawer 2, a structure is formed in which the locking engagement recess 4 is integrally molded with resin on the upper surface of the handle 6, thereby forming a structure that is easier to manufacture.

[0045] In addition, the locking engagement recess 4 formed in this way is set to be "ト"-shaped or L-shaped when viewed from above, but in the present embodiment, as described above, it is constructed to be L-shaped when viewed from above and is composed of the above-mentioned preventing recess 9 and the above-mentioned sliding allowing recess 11, and the preventing recess 9 has a length in the left-right direction and does not have a length greater than the engagement amount in the front-to-back direction of the pulling direction, and the sliding allowing recess 11 is continuously arranged with the preventing recess 9 and has a length in the front-to-back direction, and the rear end reaches the rear edge of the handle portion 6 and has an opening portion 10 for recess disengagement.

[0046] Moreover, when the pull-out body 2 is completely stored in the storage body 1, the locking engagement protrusion 5 is located at the corner of the L-shaped locking engagement recess 4. When the lateral sliding operation part 8 is slid laterally to engage the locking engagement protrusion 5 with the blocking recess 9 having a length in the left and right directions, the above-mentioned locked state is achieved. On the contrary, when the lock is released, if the lateral sliding operation part 8 is operated and the lateral sliding operation is performed until the locking engagement protrusion 5 abuts against the corner, it can be switched to the locked release state in which it can be pulled out. Since the operation is a lateral sliding operation of one action, it is configured to be very simple and quicker to perform.

[0047] In addition, the following structure is adopted: the locking engaging protrusion 5 of this embodiment is vertically arranged on the transverse sliding part 7 which is freely slidable in the left and right directions at the front part of the above-mentioned storage body 1, and the transverse sliding operation part 8 used to make the transverse sliding part 7 slide laterally is arranged in the front part of the above-mentioned storage body 1 in an exposed state.

[0048] Specifically, a structure is adopted in which a horizontal extension portion 13 overlapping with the upper portion of the handle portion 6 for pulling out the pull-out body 2 is provided at the front portion of the stackable upper plate portion 12 of the above-mentioned storage body 1, and a structure is adopted in which the above-mentioned lateral sliding portion 7 provided with the above-mentioned lateral sliding operation portion 8 and the above-mentioned locking engaging protrusion 5 is engaged with the lateral sliding guide recess 14 so as to slide freely laterally on the horizontal extension portion 13 of the storage body 1.

[0049] That is, the following structure is adopted: the above-mentioned horizontal extension part 13 at the front part of the upper plate part 12 of the above-mentioned storage body 1 is recessed in the upper surface of the above-mentioned horizontal sliding guide recess 14 in the shape of a horizontal rectangular shallow concave, and before being guided by the above-mentioned horizontal sliding guide recess 14 and hitting the left and right specified positions, stoppers or edges, the above-mentioned horizontal rectangular shaped horizontal sliding part 7 is set to a snap-in state so as to slide freely horizontally, and the above-mentioned horizontal sliding operation part 8 which becomes an operation knob in a state of protruding upward is set to an exposed state on the above-mentioned horizontal sliding part 7, and the above-mentioned locking snap-in protrusion 5 is set to a state of protruding downward on the above-mentioned horizontal sliding part 7, and is set to a penetrating vertical setting state via the horizontally long window part.

[0050] Therefore, the following structure is adopted: a locking snap-in protrusion 5 is vertically arranged from the protruding portion 13 at the front of the upper plate portion 12 of the storage main body 1 to penetrate downward through the horizontally long window portion, and the locking snap-in protrusion 5 is arranged on a horizontal sliding portion 7 that is freely slidable laterally. The locking snap-in protrusion 5 is slidably engaged with the above-mentioned locking snap-in recess 4 on the upper surface of the handle portion 6 at the upper front portion of the pull-out body 2.

[0051] In this embodiment, the operation direction and the locking and unlocking positions are displayed on the lateral sliding portion 7 or the above-mentioned horizontal extension portion 13 around it, so that the position and method of the locking operation can be visually confirmed more clearly, and the unlocking operation can be performed quickly without confusion.

[0052] In addition, the plate-shaped transverse sliding portion 7 of the present embodiment is constructed to slidably engage the vertically arranged engaging protrusion 5 with the transversely long window portion on the bottom surface of the transverse sliding guide recess 14, and can slide back and forth freely laterally before hitting the left and right edges. However, when the transverse sliding portion 7 is set in the transverse sliding guide recess 14, the groove and the protrusion are set only in the specified sliding position, that is, in a manner that the engaging protrusion 5 can be inserted into the transversely long window portion, and an anti-slip locking claw 20 is set on the engaging protrusion 5 to prevent it from slipping back.

[0053] In addition, a retaining sliding side locking protrusion 21 is provided on the left and right sides of the back side of the lateral sliding portion 7, and a retaining fixed side locking protrusion 22 is provided on the bottom surface of the sliding guide recess 14, so as to maintain a specified sliding position, wherein the retaining fixed side locking protrusion 22 passes over the retaining sliding side locking protrusion 21 and locks before it is about to slide laterally to the specified position, thereby limiting the return and performing positioning and holding.

[0054] In addition, in the present embodiment, as described above, the lock mechanism 3 is provided on the drawer body 2, so that the drawer body 2 can be easily carried by gripping the handle portion 6 and the rear upper protruding edge portion.

[0055] That is, if it is set to a locked state, the pull-out body 2 will not pop out, so the handle portion 6 for pulling out the pull-out body 2 can be held and carried with confidence. Since the locking operation can also be performed easily and quickly, the transportation also becomes easier. In addition, the lock release operation during removal can also be performed only by a lateral sliding operation of the lateral sliding operation portion 8 protruding in an exposed state on the upper part of the handle portion 6, so removal can also be performed easily and quickly.

[0056] In this embodiment, there is a forward tilt prevention mechanism 15, which prevents the above-mentioned storage body 1 and the pull-out body 2 from tilting forward due to the weight of the pull-out body 2 or the weight of the storage objects stored in the pull-out body 2 when the pull-out body 2 is pulled out and slid.

[0057] The forward tilt prevention mechanism 15 is constructed by providing a locking portion 17 in a protruding state at the lower portion of the above-mentioned storage body 1, wherein the locking portion 17 is locked with a locking receiving portion 16 which is provided in an open state at the rear inner side of the peripheral protruding edge portion of the upper plate portion 12 of the storage body 1 which becomes the lower side of the stacked body, thereby preventing the rear portion of the upper storage body 1 from tilting up, thereby preventing the above-mentioned forward tilt.

[0058] Specifically, the above-mentioned forward tilt prevention mechanism 15 of the present embodiment is constructed such that the mounting portion 19 can be freely loaded and unloaded and engaged with the mounting receiving portion 18 arranged at the lower portion of the above-mentioned storage main body 1 by flexing and restoring the engaging claws 23 arranged in a protruding state on the left and right sides of the mounting portion 19. When the mounting portion 19 is engaged and installed on the mounting receiving portion 18 by utilizing the mounting engaging claws 23, the above-mentioned engaging portion 17 is provided on the mounting portion 19, which is arranged in a protruding state from the storage main body 1 and can be hooked and engaged with the above-mentioned engaging receiving portion 16.

[0059] Although a structure in which the locking portion 17 is freely and detachably provided on the mounting portion 19 may also be adopted, in the present embodiment, a structure in which the mounting portion 19 having the locking portion 17 integrally formed therein is freely and detachably provided on the mounting supporting portion 18 or a structure in which the mounting portion 19 and the locking portion 17 can be used as components that can be installed later to select whether to install the locking portion 17 is installed, thereby, the forward tilt prevention mechanism 15 is constructed in a manner that can be switched between a state without the locking portion 17 and without the forward tilt prevention function and a state with the locking portion 17 and with the forward tilt prevention function.

[0060] Therefore, in this embodiment, the pull-out body 2 can be safely pulled out in the forward tilt prevention state, and when stacked on a stacked body without the locking receiving portion 16 for preventing forward tilt, the locking portion 17 that hinders the stacking can be easily removed and stacked.

[0061] In addition, the present invention is not limited to the present embodiment, and the specific structure of each component can be designed appropriately.
