BACKGROUND OF THE INVENTION
Field of the Invention
[0001] The present invention relates to a caulking gun.
Description of the Prior Art
[0002] A caulking gun is used to push the gel in the gel tube out. A conventional caulking
gun, such as disclosed in patents
TW M406469 or
US 6,640,998, has a pushing element, a bar-linkage assembly, and a trigger which is connected
with the bar-linkage assembly. When the trigger is pressed or pulled, the pushing
element is moved due to the motion of the bar-linkage assembly so as to bring a pushing
rod move forward. Specifically, the trigger is directly pivotally engaged with one
of the bars of the bar-linkage assembly. The motion of the bar-linkage assembly is
triggered by the pivoting of the trigger.
[0003] However, the angle of pivoting and the position of the trigger are restricted, so
the design of movement of the bars is also restricted a lot. Besides, the pressing
force of the trigger may be wasted on useless component of force in the complicated
bar-system. To move the pushing rod forward, much force is needed.
[0004] On the other hand, the complicated bar-system is difficult to manufacture and assemble.
The connections between the bars may be stuck due to rusting.
[0005] From French patent publication
FR 2071023 A5 a mastic extruder is known that comprises a bar-linkage consisting of two hingedly
connected bars and a roller. The front end of a first bar is inserted in a hole formed
in a languet which engages the pushing rod of the extruder. A second bar is pivotally
connected with the extruder housing. The hinge connecting the two bars of the bar-linkage
is lifted and lowered by means of a trigger whose one end is eccentrically shaped
and pivotally connected to the extruder housing. When the trigger is pushed, the hinge
connecting the two bars is lifted, the front end of the first bar moves forward and
thus, the languet as well as the pushing rod move forward.
SUMMARY OF THE INVENTION
[0006] The main object of the present invention is to provide a caulking gun which has a
simple structure and is easier to use.
[0007] To achieve the above and other objects, a caulking gun of the present invention includes
the features of claim 1. Further embodiments include the features of the dependent
claims.
[0008] The caulking gun of the present invention includes a main body, a pushing rod, a
pushing element, a bar-linkage assembly, and a trigger.
[0009] The main body has a first end and a second end. The main body has an operation portion.
A lower portion of the operation portion near the second end is formed with a handle
extending downward. A pushing rod penetrates the operation portion along a direction
from the second end to the first end. An end of the pushing rod near the first end
is adapted for pushing a gel in a gel tube.
[0010] A pushing element is received in the operation portion and tends to move toward the
second end under an elastic force of a first elastic element. The pushing element
is formed with a first through hole whose internal diameter is larger than an external
diameter of the pushing rod. The pushing rod is inserted through the first through
hole. The pushing element has an abutting portion at a face thereof facing the second
end. The abutting portion is located below the first through hole.
[0011] The bar-linkage assembly includes a front bar and a rear bar. An end of the rear
bar is pivotally connected to a portion of the operation portion near the second end.
An end of the front bar is pivotally connected to the rear bar. An end of the front
bar away from the rear bar abuts against the abutting portion of the pushing element.
[0012] The trigger has a pressing end and a pushing end at two opposite ends thereof. The
pressing end is more remote from the operation portion than the pushing end. The pushing
end is inserted into the operation portion. The trigger is pivotally connected to
the operation portion at a portion between the pressing end and the pushing end but
closer to the pushing end than the pressing rod. The pushing end is able to drive
a connection between the front bar and the rear bar to move upward.
[0013] When the pressing end of the trigger is pressed toward the handle, the pushing end
pushes the connection between the front bar and the rear bar upward so that the front
bar pushes the abutting portion of the pushing element toward the first end. Thereby
the pushing element inclines much with respect to the pushing rod so that the pushing
rod is grasped by the first through hole. And then the pushing element is further
moved toward the first end to drive the pushing rod to move toward the first end when
the trigger is further pressed.
[0014] The present invention will become more obvious from the following description when
taken in connection with the accompanying drawings, which show, for purpose of illustrations
only, the preferred embodiment(s) in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Please refer to Fig. 1 to Fig. 5, the caulking gun of the present invention includes
a main body 10, a pushing rod 20, a pushing element 30, a bar-linkage assembly 40,
a trigger 50, and a restriction element 60.
[0017] The main body 10 has a first end and a second end. The main body 10 has an operation
portion 11. The operation portion 11 is formed with a handle 12 extending downward
from a lower portion thereof near the second end. In the present embodiment, the lateral
view of the operation portion 11 is substantially reversed U-shaped. An opening is
formed between the upper end of the handle 12 and the lower portion of the operation
portion 11 near the first end. The upper end of the handle 12 and the lower portion
of the operation portion 11 near the first end are connected by a connecting piece
13.
[0018] The pushing rod 20 penetrates the operation portion 11 along a direction from the
second end to the first end. An end of the pushing rod 20 near the first end is adapted
for pushing a gel in a gel tube 70 out.
[0019] The pushing element 30 is received in the operation portion 11 and tends to move
toward the second end under the elastic force by a first elastic element 33. The pushing
element 30 is formed with a first through hole 31 whose internal diameter is larger
than an external diameter of the pushing rod 20. The pushing rod 20 is inserted through
the first through hole 31. The pushing element 30 has an abutting portion on a face
opposite to the first elastic element 33. The abutting portion is located below the
first through hole 31. In the present embodiment, the operation portion 11 has a blocking
element 14 near the second end. The blocking element 14 abuts against the upper portion
of the pushing element 30 so that the upper portion of the pushing element 30 may
not be over-pushed toward the second end by the elastic element 33.
[0020] The bar-linkage assembly 40 includes a front bar 41, a rear bar 42, and a roller
43. An end of the rear bar 42 is pivotally connected to the portion of the operation
portion 11 near the second end. An end of the front bar 41 is pivotally connected
to the rear bar 42. The roller 43 is arranged at the connection between the front
bar 41 and the rear bar 42. An end of the front bar 41 away from the rear bar 42 abuts
against the abutting portion of the pushing element 30. More specifically, the end
of the front bar 41 away from the rear bar 42 has a traversing axle 413. The abutting
portion of the pushing element 30 is a groove 32. The traversing axle 413 is received
in the groove 32. An angle is defined by the top faces of the front bar 41 and the
rear bar 42 therebetween. The rear bar 42 is pivotally connected to the operation
portion 11 by a pivot axle 423. In the present embodiment, each of the front bar 41
and the rear bar 42 is composed of two side portions 411, 421 and a bridge portion
412, 422 connecting the two side portion 411, 421 therebetween.
[0021] The trigger 50 has a pressing end 51 and a pushing end 52 at two opposite ends. The
pressing end 51 is more remote from the operation portion 11 than the pushing end
52. The pushing end 52 is inserted into the operation portion 11. A portion of the
trigger 50 between the pressing end 51 and the pushing end 52 but closer to the pushing
end 52 is pivotally connected to the operation portion 11. In the present embodiment,
the trigger 50 is pivotally connected to the connecting piece 13. The pushing end
52 abuts against the roller 43. When the trigger 50 is pressed to push the roller
43 upward, the distance between the pivot axle 423 and the traversing axle 413 increases,
and the angel between the front bar 41 and the rear bar 42 is also increased. Preferably,
the angle is 90 to 120 degrees when the trigger 50 is not pressed.
[0022] The restriction element 60 is arranged at the second end of the main body 10 to conditionally
restrict the pushing rod 20 from being pulled toward the second end. In the present
embodiment, the restriction element 60 has a second through hole 61, and the pushing
rod 20 is inserted through the second through hole 61. The second through hole 61
has an internal diameter larger than the external diameter of the pushing rod 20.
A second elastic element 62 is biased between the restriction element 60 and the operation
portion 20. An upper portion of the restriction element 60 is positioned to the main
body 10 so that a lower portion of the restriction element 60 is pivotable. The lower
portion of the restriction element 60 tends to move away from the main body 10 due
to the second elastic element 62. When the lower portion of the restriction element
60 is not pressed toward the main body 10, the second through hole 61 inclines with
respect to the pushing rod 20 so as to grasp the pushing rod 20. When the lower portion
of the restriction element 60 is pressed toward the main body 10, the second through
hole 61 inclines less so that the pushing rod 20 is not positioned by the second through
hole 61, as shown in Fig. 6. Preferably, an end of the second through hole 61 near
the main body 10 has a larger internal diameter than an internal diameter of an end
of the second through hole 61 remote from the main body 10. When the restricted element
60 is not pressed, the pushing rod 20 is able to be moved toward the first end but
unable to be moved toward the second end. Besides, the pushing rod 20 is inserted
through the first elastic element 33 and the second elastic element 62 so that the
first elastic element 33 and the second elastic element 62 may abut against the fringes
of the first through hole 31 and the second through hole 61.
[0023] When the pressing end 51 of the trigger 50 is pressed toward the handle 12, as shown
in Fig. 5, the roller 43 is pushed upward by the pushing end 52 so that the front
bar 41 pushes the abutting portion of the pushing element 30 toward the first end.
Thus, the pushing element 30 inclines much with respect to the pushing rod 20, so
the pushing rod 20 is grasped by the first through hole 31. At this time, the pushing
element 30 is further moved toward the first end when the trigger 50 is further pressed.
Thereby the pushing rod 20 is brought to move toward the first end to push the gel
in the gel tube 70 out. When the pushing rod 20 cannot be pushed anymore, the user
can press the restriction element 60 and pull the pushing rod 20 toward the second
end to resume the pushing rod 20 to a original position.
[0024] In another embodiment, as shown in Figs. 7 to 9, the roller is replaced by a pushing
piece 44. An end of the pushing piece 44 is pivotally connected to the connection
between the front bar 41 and the rear bar 42, and the other end of the pushing piece
44 is pivotally connected to the pushing end 52 of the trigger 50. When the trigger
50 is pressed, the pushing end 52 drives the pushing piece 44 to move upward so that
the connection between the front bar 41 and the rear bar 42 is moved upward. Thus,
by a motion of the bar-linkage assembly similar to the first embodiment, the pushing
rod 20 is moved forward.
[0025] In conclusion, the caulking gun of the present invention wastes less force in the
bar-linkage system. Besides, the structure is simple and easy to manufacture and assemble.
