A telescopic device (1) comprising a first tubular element and an extension member displaceably arranged in an axial direction within a first passageway (5) of the first tubular element, wherein the extension member is provided with a first radial protruding part (8) on a first section of the extension member and that the first section is adapted to be changed between; a first radial extent (8) of the first radial protruding part having a larger dimension than the radial extent (13) of at least a part of the first passageway and; a second radial extent (9) of the first radial protruding part having a radial extent equal to or smaller than the radial extent of at least a part of the first passageway.

A core block has an arm portion, and a yoke portion extending circumferentially at an end of the arm portion. At least the yoke portion is configured such that a plurality of core segments are stacked in multiple levels in an axial or radial direction. Each of the core blocks has engaging portions formed at respective opposite ends of the yoke portion and adapted to connect adjacent core blocks. In a first-level core segment, each of the engaging portions has a protrusion extending circumferentially from a corresponding one of the opposite ends of the yoke portion, and a recess juxtaposed radially to the protrusion and adapted to receive the protrusion of an adjacent core block. In a second-level core segment, each of the engaging portions has the protrusion and the recess provided in positionally reversed relation with those of the first-level core segment with respect to the radial direction.

A broom assembly includes a head structure and a rod structure. The head structure includes a base having a coupling face formed with a reception chamber and an opening for access into the reception chamber, and a plurality of resilient ribs provided at the periphery confining the opening and extending inwardly and radially toward a center axis of the opening. The rod structure includes a coupling member provided partially, rotatably and detachably within the reception chamber in the coupling face of the base. When the coupling member is detachably received within the reception chamber, the coupling member biases against and engages the resilient ribs so as to be prevented untimely disengaging from the base.

Each of the core blocks has engaging portions formed at respective opposite ends of the yoke portion and adapted to connect adjacent core blocks. In a first-level core segment, each of the engaging portions has a protrusion extending circumferentially from a corresponding one of the opposite ends of the yoke portion, and a recess juxtaposed radially to the protrusion and adapted to receive the protrusion of an adjacent core block. In a second-level core segment, each of the engaging portions has the protrusion and the recess provided in positionally reversed relation with those of the first-level core segment with respect to the radial direction.

A scale (1) having a scale housing (3) serving to house the weighing mechanism and the weighing electronics, which stands on a support base on at least three support points (5,5′), is designed to be connectable to and disconnectable from a display and operating unit (6). A connection element (9) is provided to produce a mechanical coupling between the scale (1) and the display and operating unit (6), which can be attached to the bottom side of the scale housing (3) and is designed to be supported on at least two support points (5) of the scale (1) and can be engaged in a self-locating way in a third point on the bottom side of the scale housing (3).

A power receptacle assembly includes a first housing, a second housing, one or more receptacle units, one or more functional receptacles, and a decorative bordered frame. Two or more through holes are disposed at lower portions of two opposing sides of the first housing to admit a hook portion formed by extending downward two outer sides of the second housing engaged with the one or more receptacle units and admit a hook portion formed by extending downward two outer sides of the one or more functional receptacle. Not only does the power receptacle feature a flexible combination of a conventional receptacle unit and a functional receptacle in operation to meet user needs and application needs, but the assembly process also features simple engagement and precise positioning.

A tool carrying device configured for removable engagement atop a stepladder and to provide elevated support for a user when the carrying device is positioned on the ground. A secure removable engagement with the top of the ladder is provided by walls descending from a top which form a skirt to surround the top end of the ladder and hold the device from sliding therefrom. Removable tool holders and shelves to hold and store tools are provided, allowing the user a secure tool box when atop a ladder and a slightly elevated working structure for tasks requiring a lower elevation for the user.
