MODULAR STORAGE SYSTEM WITH STORAGE BOX CONNECTIVITY AND EXTERNAL BOX FEATURES AND ACCESSORIES
A modular storage system of connectable, heavy-duty storage boxes, crates, rolling carts and/or dollies, work surfaces, organizers, trays, accessories is provided for internal and external item storage and organization and convenient access for use and transport, that is expandable, customizable and readily adaptable. Storage boxes have different sizes by length, width and/or height and have universal box-to-box connection system for stacking and connection to mounting accessories. Boxes have removable, customizable organization inserts (e.g., dividers, storage trays, bins, alignment trays for bins, and bins of different sizes). Box lid rib grid with bosses and undercuts expands internal organization, including cooperation with dual purpose dividers and accessories. Boxes have external mounting accessories to expand external organization. Different housing modes are provided including wall mount systems for wall or side of a truck or van, and different transport modes are provided (e.g., base box with wheels, or on a dolly or a cart).

B65D 25/06 - Partitions adapted to be fitted in two or more alternative positions
A motor unit may include: a motor including a motor shaft extending in a first direction; a body housing disposed on an outer side of the control circuit board and the motor housing; a first fixing part configured to be fixed to the working unit; a first and second vibration-proof members disposed between the body housing and the motor housing. The first fixing part is placed on a placement surface when the motor unit is placed on the placement surface. In an up-down direction perpendicular to the placement surface, at least a part of the first vibration-proof member and at least a part of the second vibration-proof member may be disposed below an upper end of the motor when the motor unit is placed on the placement surface. When the motor unit is viewed along the first direction, the motor may be disposed between the first second vibration-proof members.

A motor unit may include: a body housing including an accommodating part including a first wall, a first battery receptacle and a second battery receptacle that are disposed on the first wall; and a motor disposed inside the accommodating part and configured to drive a working unit. The first receptacle may be configured to have a first battery attached thereto, the first battery being configured to slide along the first wall. The second receptacle may be configured to have a second battery attached thereto, the second battery being configured to slide along the first wall. The first battery may include a first side surface. The second battery may include a second side surface which may face the first side surface and be disposed parallel to the first side surface when the first battery is attached to the first receptacle and the second battery is attached to the second receptacle.
A display device may include: a first light emitting part that emits light; a second light emitting part that emits light; and a housing. The housing may include: a transmissive part defining an internal space in which the first and second light emitting parts are disposed, and that transmits light from the space of the housing to outside the housing; a partition wall part integrally formed with the transmissive part and partitioning the space of the housing into a first accommodating space where the first light emitting part is disposed and a second accommodating space where the second light emitting part is disposed; and a first shielding part disposed on a surface of the transmissive part, having a light transmittance smaller than a light transmittance of the transmissive part, and defining a first display element in the first accommodating space and a second display element in the second accommodating space.
A cleaner includes: a main body housing; a dust collecting housing detachably attached to the main body housing and having an air-intake port; a suction assembly housed in the main body housing and configured to generate a suction force; a first filter unit housed in the dust collecting housing and including a first filter to which air sucked through the air-intake port is supplied and a first support member supporting the first filter; a filter support mechanism configured to fix the first filter unit to the main body housing at a fixed position in a rotation direction when the first filter unit is rotated in a normal rotation direction with respect to the main body housing; and a reverse rotation limiting mechanism configured to restrict the first filter unit from being rotated beyond a limit angle from the fixed position in a reverse rotation direction.
A blade for a reciprocating saw includes: an elongated body having one end that is detachably attachable to the reciprocating saw; and at least one hard tip having a greater hardness than the body and being bonded to the body. The body includes a cutting edge part having a plurality of teeth arranged along the length direction and a back part extending along the length direction on the side opposite to the cutting edge part in a width direction. The cutting edge part includes at least one curved part. The curved part(s) is (are each) configured so that a cutting edge line, which is a line connecting the tips of a plurality of teeth disposed along the curved part(s), curves in a concave manner toward the back part. The at least one hard tip is bonded to at least one of the plurality of teeth.
