With reference to
The shelf stand (10) has two side surfaces and at least one slot (12). Each slot (12) is defined longitudinally in each side surface of the shelf stand (10) and has an inner surface, two opposite sidewalls and two ribs (11) are formed along the sidewalls. Each rib (11) has an outside surface, multiple openings (110) and multiple optional scales (111). The openings (110) are separately formed longitudinally in the ribs (11). The scale (111) are formed on the outside surface of each rib (11).
With further reference to
The mounting tabs (21)(22) are opposite to each other. Each mounting tab (21)(22) has a mounting surface defined perpendicularly to the side surface of the shelf stand (10) and has a side, a mounting portion (27) and at least two mounting holes (220). The mounting portion (27) is formed on the side of the primary tab (22) and are perpendicular to the mounting surface of the primary tab (22) and are parallel to the inner surface of the slot (12) in the shelf stand (10) and has multiple threaded holes (270). The threaded holes (270) are formed in the mounting portion (27) corresponding to the inner surface of the secondary and primary mounting tabs (21)(22) and has optional inner threads.
The mounting brackets (30) are mounted slidably in the slot (12) from the openings (110). Each mounting bracket (30) comprises a stage (32) and a fixing element (31). The stage (32) and the fixing element (31) can be integrally formed as a single piece. The stage (32) has a contact surface, a front surface, a through hole (320), multiple resilient protrusions (322) and two optional holding protrusions (321). The contacting surface faces the inner surface of the slot (12). The resilient protrusions (322) are formed on the contact surface to rub against the inner surface of the slot (12) to generate a friction for supporting the mounting bracket (30). The through hole (320) is formed in the stage (32). The holding protrusions (321) are formed oppositely on the front surface of the stage (32). The fixing element (31) is securely attached to the front surface of the stage (32) and has a threaded hole (310). The threaded hole (310) is formed through the fixing element (31), aligns with the through hole (320) in the stage (32) and corresponds to one of the threaded holes (270) in the mounting portion (27).
The spacer (25) has a flat surface and optionally have two apertures (250) or a flat bottom surface (with reference to
The pad (23) is mounted on the mounting surface of the primary mounting tab (22) and is connected with the spacer (25) by a connector to cushion the pressure on the spacer (25) and has at least two through holes (230). The through holes (230) are formed through the pad (23) and respectively correspond to the mounting holes (220) and each has a diameter.
The mounting screws (24) are mounted respectively through the mounting holes (220) in the primary tab (22). Each mounting screw (24) has a diameter, an end and a tip (240). The diameter of the mounting screw (24) is greater than the diameter of the through holes (230) in the pad (23) and the apertures (250) in the spacer (25). The tip (240) is formed in the end of the mounting screw (24), has a diameter small than the diameter of the through holes (230) in the pad (23).
The mounting screws (24) screw respectively into the mounting holes (220), and the tips (240) extend respectively through the through holes (230) in the pad (23) and may protrude into and out from the apertures (250) of the spacer (25) when the apertures (250) are defined in the spacer (25) or abut against the flat bottom surface of the spacer (25) when no aperture (250) is defined in the spacer (25).
The fastening screws (33) are screwed into the threaded holes (270) in the mounting portion (27) and the threaded holes (310) in the fixing element (31) and optionally extend into the through holes (320) in the stages (32). Therefore, the mounting portion (27) and the mounting bracket (30) clamp the rib (11) tightly to securely hold the mounting brackets (30) and the mounting tabs (21)(22) in the slot (12).
With further reference to
With further reference to
Since the position of the containing element can be adjusted by moving the mounting tabs (21)(22) along the slot (12), the shelf stand (10) of the present invention is more convenient to use.
Furthermore, the containing element is clamped by the mounting tabs (21)(22) so the containing element can be held more stable, whether the containing element become brittle after a long-term use.
Additionally, the multiple openings (110) are formed separately along the ribs (11) so people can select a suitable opening (110) to put in the mounting bracket (30) when the shelf stand (10) is set on the ground. The scale (111) in the surface of each rib (11) can help people to adjust the level of the containing element. The friction generated by the resilient protrusions (322) rubbing against the inner surface of the slot (12) can help to retain the mounting tabs (21)(22) before being held, such that people have no need to keep hold the mounting tabs (21)(22). Above said advantage make the shelf stand in accordance with present invention be able to provide more convenience to people.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
