Field of the Invention

[0001] The present invention relates to a magnetic drilling machine. More particularly, the present invention relates to a portable magnetic drilling machine.

Background of the Invention

[0002] Generally, in magnetic drilling machines, a handle is used mainly for lifting and carrying the machine from one place to another. In most magnetic drilling machines, the handle is on the side portion of the magnetic drilling machine, which tends to tilt the machine about 45 degrees, making it difficult to lift and carry. Also, a user has to use both his hands to lift or carry the machine from one place to another, which causes difficulty in handling the machine due to the offside placement of the handle on the machine.

[0003] Also, the coolant bottle is placed on the magnetic drilling machine's side portion, making it difficult to lift and carry for the user. There is a chance of spilling the coolant while moving the machine from one place to another. Further, there is a limitation in the size of the coolant bottle, which requires the frequent filling of the coolant in the bottle. [0004] Therefore, there is a need for a portable magnetic drilling machine which can overcome the problems of the existing prior art.

[0017] An embodiment of this invention, illustrating its features, will now be described in detail. The words "comprising," "having," "containing," and "including," and other forms thereof, are intended to be equivalent in meaning and be open-ended in that an item or items following any one of these words is not meant to be an exhaustive listing of such item or items or meant to be limited to only the listed item or items.

[0018] The terms “first,” “second,” and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another, and the terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. [0019] The present invention provides a portable magnetic drilling machine. Also, the portable magnetic drilling machine is easy to lift and carry from one place to another. Further, the portable magnetic drilling machine reduces the effort of a person in holding the machine. Furthermore, the portable magnetic drilling machine is simple in construction and easy in operation.

[0020] Referring now to figures 1, 2 and 3, the portable magnetic drilling machine (100) in accordance with the present invention is illustrated. The portable magnetic drilling machine (100) includes a base (10), a pillar (30), a drilling bit assembly (45) and a handle (20). The portable magnetic drilling machine (100) from hereinafter referred to as "The machine (100)”.

[0021] The base (10) of the machine (100) is bolted to the ground to support the weight of the machine (100). The pillar (30) is an elongated member which is extended vertically from the base (10). The drilling bit assembly (45) is slidably arranged on a side portion of the pillar (30). The drilling bit assembly (45) is a cutting tool used to make or enlarge holes in solid metal. Drill bits are used with a manual-operated drill or drill press equipped with a chuck.

[0022] In another embodiment, the base (10) of the machine (100) is an electromagnetic base to hold the machine (100) by magnetic force on a steel plate or a beam. [0023] The handle (20) is configured to a central part (60) of the top portion (50) of the machine (100) for lifting and carrying the machine (100) with minimal wobbling. The top portion (50) of the machine (100) is a flat surface to avoid trembling of the machine (100). In the present embodiment, the top portion (50) is rectangular in shape. But it may be obvious to a person skilled in the art to design the top portion (50) of any geometry (shape and size), which reduces the trembling of the machine (100). Also, a cover (20c) is provided to protect the handle from slipping. Also, the cover (20c) provides a grip while holding the handle (20). It may be obvious to a person skilled in the art to use the cover of any material which provides proper grip in holding the handle (20). Specifically, in the present embodiment, the handle (20) is configured to the central part (60) of the machine (100). The central part (60) of the machine (100) is collinear with the centre of gravity of the portable magnetic drilling machine (100).

[0024] Also, the centre of gravity keeps the machine (100) straight while lifting or moving the machine (100) from one place to another, thereby making the machine (100) easy to lift and carry. But it may be obvious to a person skilled in the art to configure the handle (20) anywhere on the top portion (50) of the machine (100) for easy lifting.

[0025] Further, the sides of the handle (20) are arcuate in shape (as shown in figure 1). It may be obvious to a person skilled in the art to make a handle of any shape and size. The handle (20) and the top portion (50) of the machine (100) are integral. It may be obvious to a person skilled in the art to make the handle (20) of any material such as metal, plastic, rubber and the like. Specifically, in the present embodiment, the handle (20) has a left side (20a) and a right side (20b) (as shown in Figures 1 and 2). The left side (20a) of the handle (20) and right side (20b) of the handle (20) is configured on the central part (60) of the top portion (50) of the machine (100) by using mechanical fasteners such as bolts or screws (as shown in figure 1).

[0026] The central part (60) is the mid-point on the width of the top portion (50) of the machine (100). It may be obvious to a person skilled in the art to configure the handle (20) on the central part (60) of the top portion (50) of the machine (100) by any securing means.

[0027] In an alternate embodiment, the machine (100) includes a locking assembly (not shown) for the handle (20). For example, if the handle (20) is in the unfolded position, the handle (20) moves angularly on the first side and second side of the machine (100). The person handling the machine (100) can fix the handle (20) anywhere between the first side (20a) and the second side (20b) at any angle using the locking assembly. The handle (20) may have slots arranged thereon to lock the locking rod at any angle of the handle (20). In an embodiment, the locking assembly may be having a ratchet mechanism to lock the handle (20) at a particular angle. [0028] Moreover, the pillar (30) is linked to a control panel box (40) using a rib, resulting in increased vacant space between the rear of the pillar (30) and the control panel box (40). This particular configuration of empty space is designed to accommodate a larger plastic coolant bottle. The coolant capacity and the size of the bottle exceed those of competitors. The competing manufacturers typically place the plastic coolant bottle on top or on the side of the machine. However, in the present invention, the coolant bottle conveniently fits into the empty space within the main body of the machine.

[0029] Therefore, the portable magnetic drilling machine (100) has the advantage of providing a portable magnetic drilling machine (100). Also, the portable magnetic drilling machine (100) is easy to lift and carry from one place to another. Further, the portable magnetic drilling machine (100) reduces the effort of a person holding the machine. Furthermore, the portable magnetic drilling machine (100) is simple in construction and easy in operation. Additionally, when packing the machine in a plastic or metal carrying case, there's no necessity to detach the coolant bottle from the machine. While other machines remove the coolant bottle during packaging for transport in plastic or metal carrying cases.
