Abstract

A caster device with detachable casters has a base 10, multiple positioning assemblies 20 formed on the base 10, each positioning assembly 20 comprising a holder (21 Fig 6). Caster 30 is then slidably and detachably mounted within an elongate channel between the positioning assemblies 20 and the holder. The base may also have a perimeter edge, multiple mounting holes 12 and a locking protrusion 23 wherein the locking protrusion has a proximal edge 232, a distal surface 231 and a guiding surface 233 extending between the two. When the caster is slid into place the locking protrusion moves into the mounting hole 12 and then returns into position (Fig 5) locking the caster in place. A positioning device may include a resilient member, for example a spring (223 Fig 6) which is provided with a positioning ball (224) that engages indentation (311) on the mounting panel. The caster device can be used with a portable dehumidifier.

Description

CASTER DEVICE WITH DETACHABLE CASTERS FOR PORTABLE
DEhUMIDIFIER
1. Field of the Invention
The present invention relates to a caster device for a portable dehumidifier, especially to a caster device with detachable casters to allow convenient replacement of the casters.
2. Description of the Prior Arts
Unlike a stationary air conditioner such as window-type air conditioner or split-type air conditioner that is fixed high on a window or a wall, a portable air conditioner is placed on a ground without causing damage to the window or the wall and is moved and stored conveniently. Therefore, the portable air conditioner becomes popular. A dehumidifier is one kind of the air conditioners that regulates indoor humidity.
A conventional portable dehumidifier has multiple casters being securely attached to a bottom of the conventional portable dehumidifier for convenient moves of the conventional portable dehumidifier. However, the assembling processes are complicated while attaching the casters to the bottom of the conventional portable dehumidifier one by one with fasteners such as screws and the like. Furthermore, a broken caster is hard to detach from the conventional portable dehumidifier to replace with a new caster.
The main objective of the present invention is to provide a caster device with detachable casters for a portable dehumidifier. The caster device has a base mounted on a bottom of the portable dehumidifier, multiple positioning assemblies formed on the base and multiple casters respectively and detachably mounted between the positioning assemblies. Therefore, the casters are easily attached to the base for use or detached from the base for clean, repair or replacement.

With reference to Figs. 1 and 2, a caster device with detachable casters in accordance with the present invention is mounted on a bottom of a portable dehumidifier (40) and comprises a base (10), multiple positioning assemblies (20) and multiple casters (30).
With further reference to Fig. 4, the base (10) is securely mounted on the bottom of the portable dehumidifier (40), has a top panel, and may have a perimeter panel (11), multiple mounting holes (12) and multiple mounting walls. The mounting holes (12) are separately formed through the top panel of the base (10). The mounting walls of the base (10) are respectively formed around the mounting holes (12) of the base (10).
With further reference to Figs. 3 and 6, the positioning assemblies (20) are formed on the top panel of the base (10). Each positioning assembly (20) has two holders (21) and may have at least one abutting protrusion (22), a locking protrusion (23), at least one resilient device (223) and at least one positioning ball (224).
The holders (21) are separately and parallelly formed on and protrude downwardly from the top panel of the base (10) and may be formed between the perimeter panel (11) and a corresponding mounting hole (12) of the base (10). Each holder (21) has a distal edge, a support (211) and an elongated recess (212). The support (211) is formed transversely on the distal edge of the holder (21). The support (211) of one holder (21) of each positioning assembly (20) is toward the support (211) of the other holder (21) of the positioning assembly (20). The elongated recess (212) is formed between the top panel of the base (10) and the support (211) and may have two opposite open ends. The open ends of the elongated recess (212) respectively correspond to the perimeter panel (11) and the corresponding mounting hole (12) of the base (10).
With further reference to Fig. 7, the at least one abutting protrusion (22) is formed on and protrude downwardly from the top panel of the base (10) between the holders (21). Each abutting protrusion (22) has a distal surface (221) and may have at least one mounting recess (222). The distal surface (221) is parallel to the top panel of the base (10) and alongside the elongated recesses (212) of the holders (21). The at least one mounting recess (222) is formed in the distal surface (221) of the abutting protrusion (22). Each mounting recess (222) has a taper open end.
With further reference to Fig. 5, the locking protrusion (23) protrudes from a corresponding mounting wall of the base (10), is mounted in the corresponding mounting hole (12) of the base (10) and has a proximal edge (232), a distal surface (231) and a guiding surface (233). The proximal edge (232) is formed on the corresponding mounting wall of the base (10) and is resilient to allow the locking protrusion (23) to be pivoted in the mounting hole (12) of the base (10). The distal surface (231) is perpendicular to the top panel of the base (10) and has a distal edge. The guiding surface (233) is formed between the proximal edge (232) of the locking protrusion (23) and the distal edge of the distal surface (231).
Each resilient device (223) is mounted in a corresponding mounting recess (222) of the abutting protrusion (22) and may be a spring.
Each positioning ball (224) is mounted in a corresponding mounting recess (222) of the abutting protrusion (22), is pushed by a corresponding resilient device (223) and protrudes out of the taper open end of the corresponding mounting recess (222) of the abutting protrusion (22).
The casters (30) are respectively and detachably mounted between the positioning assemblies (20). Each caster (30) has a mounting panel (31) and a wheel (32).
The mounting panel (31) is mounted in the elongated recesses (212) of the holders (21), is mounted on the supports (211) of the holders (21) of a corresponding positioning assembly (20), has a perimeter edge, a positioning surface and a supporting surface and may have at least one indentation (311).
The positioning surface of the mounting panel (31) corresponds to the top panel of the base (10) and may correspond to the distal surface (221) of the abutting protrusion (22). The supporting surface of the mounting panel (31) corresponds to and is mounted on the supports (211) of the holders (21) of the corresponding positioning assembly (20). The at least one indentation (311) is formed in the positioning surface of the mounting panel (31), selectively aligns with the mounting recess (222) of the abutting protrusion (22) and selectively engage the positioning ball (224) in the mounting recess (222).
The wheel (32) is mounted securely on the supporting surface of the mounting panel (31) and is mounted slidably between the holders (22) of the corresponding positioning assembly (20).
With reference to Fig. 4, the perimeter edge of the mounting panel (31) of the caster (30) moves along the guiding surface (233) of the locking protrusion (23) of the corresponding positioning assembly (20) and presses the locking protrusion (23). Therefore, when the mounting panel (31) of the caster (30) slides into the elongated recesses (212) of the holders (21) of the corresponding positioning assembly (20), the locking protrusion (23) springs back to its original position and holds the mounting panel (31) of the caster (30) securely between the perimeter panel (11) of the base (10), the holders (21) of the corresponding positioning assembly (20) and the distal surface (231) of the locking protrusion (23). Afterwards, just pressing the locking protrusion (23) of the positioning assembly (20), the caster (30) is easily detached from the base (10).
The caster device with detachable casters for the portable dehumidifier as described has the following advantages. The casters (30) are easily attached to the base (10) without any fasteners for use and are also easily detached from the base (10) for clean, repair or replacement.
