Abstract
A magnetic retainer includes a molded one-piece plastic mounting member having a bowl-shaped part and an elongated part. The bowl-shaped part includes a base formed with a plurality retaining holes, and a peripheral wall extending upwardly from the base. The elongated part projects from the peripheral wall and is formed with an elongated groove. A magnet is fixed in each of the retaining holes in the base. A magnet-holding frame is fitted snugly in the elongated groove in the elongated part and defines a holding groove. An elongated magnetic unit is mounted securely in the holding groove in the magnet-holding frame.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a retainer, more particularly to a magnetic retainer for retaining articles thereon by magnetic attraction.




2. Description of the Related Art




A conventional magnetic retainer, as shown in

FIG. 1

, generally includes a holding member


1


and an elongated magnetic bar


2


. The holding member


1


includes a base plate


101


which is adapted to be mounted on a wall, and a magnet-holding part


102


disposed on and cooperating with the base plate


101


to define a magnet-retention groove


103


therebetween. The magnetic bar


2


is mounted in the magnet-retention groove


103


.




The conventional magnetic retainer is suitable specially for retaining long tools, such as spanner, screw drivers, files, etc., thereon, but retention of a variety of articles, like screws, bolts, nuts, etc., is not appropriate due to the elongated configuration of the holding member


1


.




SUMMARY OF THE INVENTION




Therefore, the object of this invention is to provide a magnetic retainer which is capable of retaining a plurality of articles regardless of their sizes and lengths so as to overcome the aforesaid disadvantage of the prior art.




According to the present invention, the magnetic retainer includes: a molded one-piece plastic mounting member including a bowl-shaped part and an elongated part integrally formed with the bowl-shaped part, the bowl-shaped part including a base that has top and bottom faces, and a peripheral wall extending upwardly from the top face of the base to define a receiving space therebetween, and having a top end face distal from the base, the base being formed with a plurality retaining holes, each of which is defined by a hole-confining wall, the elongated part projecting outwardly and laterally from the peripheral wall, and having a top face and formed with an elongated groove which is defined by a groove-confining wall, the groove-confining wall having two opposite ends and being formed with two opposite shoulders that project respectively from the opposite ends of the groove-confining wall into the groove; a plurality of magnets, each of which is fixed in a respective one of the retaining holes in the base; a metal sheet disposed within the receiving space and attached to the top face of the base through magnetic attraction of the magnets; a covering disc attached securely to the bottom face of the base to cover the retaining holes so as to prevent removal of the magnets from the retaining holes; a magnet-holding frame fitted in the elongated groove, seated on the shoulders, defining a holding groove, and having two opposite ends; and an elongated magnetic unit mounted securely in the holding groove in the magnet-holding frame.

FIG. 2

is an exploded perspective view of the preferred embodiment of a magnetic retainer according to the present invention for retaining articles thereon;





FIG. 3

is a schematic sectional view of the preferred embodiment; and





FIG. 4

is a front view to illustrate the preferred embodiment in a state of use.











DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIGS. 2 and 3

, the preferred embodiment of a magnetic retainer according to the present invention is shown to include a molded one-piece plastic mounting member


10


, a plurality of annular magnets


20


(only one is shown in FIG.


2


), a metal sheet


22


, a covering disc


40


, a U-shaped magnet-holding frame


33


, an elongated magnetic unit


30


, and an adhesive tape


34


.




As illustrated, the mounting member


10


includes a bowl-shaped part


12


and an elongated part


13


integrally formed with the bowl-shaped part


12


. The bowl-shaped part


12


includes a base


11


that has top and bottom faces


111


,


112


, and a peripheral wall


14


that extends upwardly from the top face


111


of the base


11


to define a receiving space therebetween, and that has a top end face


121


in the form of a flange. The base


11


is formed with a plurality retaining holes


113


, each of which is defined by a hole-confining wall (


113


W) The elongated part


13


projects outwardly and laterally from the peripheral wall


14


, and has a top face


131


that is disposed at an elevation higher than the top end face


121


of the peripheral wall


14


. The top face


131


of the elongated part


13


is formed with an elongated groove


130


which is defined by a groove-confining wall (


130


W). The groove-confining wall (


130


W) has two opposite ends


133


, and is formed with two opposite shoulders


132


that project respectively from the opposite ends


133


of the groove-confining wall (


130


W) into the groove


130


.




Each of the annular magnets


20


is press-fitted in a respective one of the retaining holes


113


in the base


11


and engages frictionally the hole-confining wall (


113


W) that defines the respective one of the retaining holes


113


.




The metal sheet


22


is disposed within the receiving space of the mounting member


10


, and is attached to the top face


111


of the base


11


through magnetic attraction of the annular magnets


20


.




The covering disc


40


is attached securely to the bottom face


112


of the base


11


to cover the retaining holes


113


so as to prevent removal of the annular magnets


20


from the retaining holes


113


in the base


11


.




The magnet-holding frame


33


is fitted snugly in the elongated groove


130


, is seated on the shoulders


132


of the groove-confining wall (


130


W), defines a holding groove


330


, and has two opposite ends.




The elongated magnetic unit


30


is mounted securely in the holding groove


330


in the magnet-holding frame


33


, and has a top face flush with the top face


131


of the elongated part


13


. In the preferred embodiment, the elongated magnetic unit


30


is formed by four separate magnetic bar pieces


32


.




The adhesive tape


34


is attached adhesively to the top face of the magnetic unit


30


, and to the opposite ends of the magnet-holding frame


33


.




Referring to

FIG. 4

, during use, the bowl-shaped part


12


can be mounted on a magnetically attractive wall, such as a car body, or on a concrete wall through a mounting hole formed in the top end face


121


of the peripheral wall


14


. Small articles, such as screws, driving bits, washers and nuts, can be retained in the receiving space of the bowl-shaped part


12


by virtue of magnetic attraction, while long tools, such as screwdrivers, spanners, files, etc., can be retained on the elongated part


13


by virtue of the magnetic unit


30


.




Since the magnetic retainer of the present invention can retain magnetically a variety of articles regardless of their lengths and sizes, the aforesaid disadvantage of the prior art can be overcome, accordingly.




With this invention thus explained, it is apparent that numerous modifications and variations can be made without departing from the scope and spirit of this invention. It is therefore intended that the invention be limited only as indicated in the appended claims.
