  However, in the case of Patent Document 1 and Patent Document 2 described above, students purchase their own lockers at the time of enrollment, use their personal names as personal lockers while attending school, and use them as a memorial box at the time of graduation. As a so-called personal locker system that can be taken home, it lacks convenience.

  That is, in the case of the above-mentioned Patent Document 2, since the upper plate of the lower shelf unit is also used as the bottom plate of the upper shelf unit, when taking a locker dedicated to the home as a memorial box after use, Since the bottom plate of the upper shelf unit is missing, the upper shelf unit cannot be taken home individually because the original form of use as a locker is impaired.

  Further, in the case of the above-mentioned Patent Document 1, the structure of the locker itself is not a structure in which a plastic locker having the same structure as the lower stage can be stacked and supported on the ceiling panel. There is a risk that the upper rocker may fall due to external impact or earthquake motion.

  Therefore, the present invention was created in view of the existing circumstances as described above, and as a personal locker system, it can be used in multiple stages when used, and after use it can be used as a locker. It is an object of the present invention to provide a plastic multi-stage rocker device that can be individually brought home without damage.

In order to solve the above-described problems, in the present invention, a plurality of shelf units assembled from a bottom plate, a back plate, two left and right side plates, a top plate, and a front door formed of plastic are arranged in the upper and lower stages. A stackable multi-stage rocker device that fits over both the fitting groove formed on the top surface of the top shelf of the lower shelf unit and the fitting groove formed on the bottom surface of the bottom plate of the upper shelf unit. And a joint member that can support and fix the two shelf units to each other, and the center of each of the upper and lower surfaces of the joint member that fits into the fitting groove has a partition wall shape formed in the middle of the fitting groove. It has a recessed part for engaging with a rib, It is characterized by the above-mentioned.

  The fitting grooves are formed on the rear edge and the left and right edges of the upper surface of the top plate and the lower surface of the bottom plate so as to correspond to the attachment positions of the back plate and the left and right side plates in the upper and lower stages.

  A lid for closing the fitting groove after removing the joint member when each of the upper and lower shelf units is brought home individually is provided.

  According to the present invention, as a personal locker system, it can be used by being stacked in a plurality of stages at the time of use, and after use, it can be brought home individually without impairing the original use form as a locker.

  That is, in the present invention, both shelf units are fitted across both the fitting groove formed on the top surface of the top plate of the lower shelf unit and the fitting groove formed on the bottom surface of the bottom plate of the upper shelf unit. Since it is equipped with joint members that can be supported and fixed to each other, the upper and lower shelf units are separated after use and each joint member is removed from each fitting groove without damaging the original use form as a rocker. Can be taken home individually.

  In particular, a personal locker system can be easily constructed by using the multistage locker device according to the present invention. With this personal locker system, students can purchase their own lockers at the time of enrollment, fill in their names as personal lockers while they are studying, and take them home as a memorial box when they graduate System. In this system, the locker can be easily moved when it is advanced, and the locker taken home after graduation can be taken back to the store for recycling. As such a personal locker system, the multistage locker device according to the present invention can be used.

  The fitting grooves are formed in the rear and left and right edges of the top plate bottom surface and the bottom plate bottom surface, respectively, so as to correspond to the mounting positions of the back plate and the left and right side plates in the upper and lower stages. The support of the upper shelf unit becomes strong, and the upper locker can be prevented from falling due to an external impact or earthquake motion.

  Since there is a recess at each center of the upper and lower surfaces of the joint member that fits into the fitting groove to engage with a partition wall-like rib formed in the middle of the fitting groove, the upper and lower shelf units are connected to each other. Can be reliably prevented.

  When each of the upper and lower shelf units is brought home individually, since it has a lid for closing the fitting groove after removing the joint member, the appearance of each shelf unit brought home individually can be improved. It is possible to improve and reduce the image as a used product.

  It is a front view of the shelf unit of the upper stage which shows one form for carrying out the present invention.   It is a front view of the state which is similarly using the shelf unit stacked up and down two steps.   It is a perspective view of the state where the shelf unit is similarly stacked and used in two stages.   It is a disassembled perspective view of the state which similarly assembles each of the top plate of a lower shelf unit, the bottom plate of an upper shelf unit, and a joint member.   It is a disassembled perspective view of the state which similarly assembles the upper shelf unit.   Similarly, the structural example of a top plate or a baseplate is shown, (a) is a top view, (b) is a bottom view.   Similarly, an example of a hook mechanism part for assembling and fixing a back plate and two left and right side plates to a bottom plate or a top plate is shown, (a) is a sectional view before locking, and (b) is a state after locking.
