Abstract
A trowel includes a blade, a handle having two ends formed integral with the blade with such as a molding or a forging process. An outer cover is disposed on the outer peripheral portion of the handle by such as a molding process for allowing the users to comfortably grasp the handle. The ends of the handle are formed integral with two seats and two ramps of the blade, and each has one or more notches for receiving bulges of the outer cover and for solidly securing the outer cover onto the handle and for preventing the outer cover from moving relative to the handle.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a trowel, and more particularly to a trowel having an integral and comfortable handle.
2. Description of the Prior Art
Various kinds of typical trowels have been developed and used today. U.S. Pat. No. 4,884,312 to Clark discloses one of the trowels including a handle having one end secured onto a metal blade. The handle includes a hollow construction for weight reducing purposes. However, the handle has only one end secured to the metal blade, such that the handle may not be solidly secured onto the metal blade and may be easily disengaged from the metal blade after use.
U.S. Pat. No. 5,327,612 to Kelsay discloses the other typical trowel or tool including a metal blade having a shank and a handle tang extended from the metal blade, and a handle secured onto the handle tang. The handle also may not be solidly secured onto the handle tang and may be easily disengaged from the handle tang after use.
U.S. Pat. No. 5,781,956 to Kelsay et al. discloses a further typical trowel including a handle having one or two ends secured onto a metal blade. The handle includes a hollow construction for weight reducing purposes. However, the handle may also have a good chance to be disengaged from the metal blade after use and after the fasteners are disengaged from the handle and/or the metal blade.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional trowels.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a trowel including an integral and comfortable handle.
In accordance with one aspect of the invention, there is provided a trowel comprising a blade, a handle including two ends formed integral with the blade and solidly secured to the blade, or formed as an integral one piece with the blade, and including an outer peripheral portion, and an outer cover disposed on the outer peripheral portion of the handle for allowing the users to comfortably hold or grasp the handle.
The blade includes a pair of seats extended upward therefrom, the ends of the handle are formed integral and secured to the seats of the blade.
The blade includes a pair of ramps provided and extended between the seats and the blade for reinforcing the seats.
The ends of the handle each includes at least one notch formed therein. The outer cover includes at least one protrusion extended inward therefrom and engaged into the notches of the handle for solidly securing the outer cover onto the handle and for preventing the outer cover from moving relative to the handle.
The handle includes at least one bulge extended outward therefrom, the outer cover includes at least one orifice formed therein for receiving the bulge of the handle and for solidly securing the outer cover onto the handle and for preventing the outer cover from moving relative to the handle.
The handle includes at least one groove formed therein for weight reducing purposes. The groove of the handle includes an open end, the handle includes a cap engaged onto the open end of the handle for blocking the open end of the handle, the cap is engaged between the handle and the outer cover.
Further objectives and advantages of the present invention will become apparent from a careful reading of a detailed description provided hereinbelow, with appropriate reference to accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings, and initially to
FIGS. 1-4
, a trowel in accordance with the present invention comprises a blade
10
, such as a metal blade
10
, preferably made of magnesium and/or the alloys thereof, and a handle
11
provided or formed on top of the blade
10
. For example, the blade
10
includes a pair of bulges or seats
14
formed or extended or provided on top thereof, and a pair of ramps
19
formed or provided between the seats
14
and the outer portions of the blade
10
for reinforcing the seats
14
. The handle
11
includes two ends
17
formed integral on the seats
14
respectively and each having one or more notches or cut off portions, such as a pair of opposite notches
18
formed therein, for such as the weight reducing purposes.
As best shown in
FIGS. 2 and 3
, the handle
11
includes a longitudinal or a horizontal or an upper portion or a middle portion Ill having a blind hole or a groove
12
formed therein for such as the weight reducing purposes. The groove
12
of the handle
11
includes a blind end and an open end. A cap
15
may be engaged onto the open end of the groove
12
of the handle
11
for blocking the groove
12
of the handle
11
, and is also shown in
FIGS. 5 and 6
. The handle
11
includes one or more bulges
13
extended outward therefrom, such as laterally extended outward therefrom, onto which the trademark or the other information may be applied. The handle
11
and the metal blade
10
may be formed integral with each other in a molding process, a forging process, or the like.
A soft and/or resilient sleeve or an outer cover
16
may further be provided and attached or disposed onto the outer peripheral portion of the handle
11
, with such as a molding process, and may be made of gel, rubber, foamable, spongy materials, or the like, for allowing the users to comfortably hold and grasp the handle
11
of the trowel. The cap
15
is preferably engaged onto the open end of the groove
12
of the handle
11
before the outer cover
16
is engaged or provided onto the handle
11
, for allowing the cap
15
to be solidly retained in place, best shown in FIG.
2
.
The outer cover
16
includes one or more protrusions
161
extended inward therefrom (
FIG. 3
) and engaged or molded into the notches
18
of the handle
11
, for allowing the outer cover
16
to be solidly secured onto the handle
11
and for preventing the outer cover
16
from rotating or moving relative to the handle
11
. The outer cover
16
further includes one or more orifices
163
formed therein (
FIG. 3
) for receiving the bulges
13
of the handle
11
, and for further allowing the outer cover
16
to be solidly secured onto the handle
11
and for further preventing the outer cover
16
from rotating or moving relative to the handle
11
. The bulges
13
of the handle
11
preferably flush with the outer surface of the outer cover
16
, best shown in FIG.
Referring next to
FIGS. 5 and 6
, without the provision or the formation of the notches
18
in the handle
11
, the outer cover
16
(
FIGS. 1-3
) may also be solidly engaged onto the handle
11
with the molding process, and may also include an engagement of the bulges
13
of the handle
11
in the orifices
163
(
FIG. 3
) of the outer cover
16
, such that the outer cover
16
may also be solidly secured onto the handle
11
and may also be prevented from rotating or moving relative to the handle
11
.
It is to be noted that the handle
11
includes two ends solidly formed or coupled to the metal blade
10
and formed as an integral one piece with the metal blade
10
, such that the handle
11
may be solidly secured to the metal blade
10
and will not be disengaged from the metal blade
10
. No further assembling processes are required for assembling the handle
11
onto the metal blade
10
. In addition, the outer cover
16
may be solidly provided or applied or attached onto the handle
11
with the molding process, and will not be disengaged from the handle
11
after use.
Accordingly, the trowel in accordance with the present invention includes an integral and comfortable handle.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
