JPS582465Y2 - Caulking gun with device for opening filler storage container - Google Patents

Description

[Detailed description of the invention] This invention is equipped with a device that opens the nozzle of a filler storage container, which is used when filling and concealing gaps between the window frame and the glass inserted therein, joints of aluminum sash, etc. with filler. This is about a caulking gun.

An embodiment of the present invention will be described below with reference to the drawings.

1 is a caulking gun; 2 is an outer casing into which is loaded a filler storage container A consisting of a cylindrical body that is equipped with an end nozzle a and stores the filler; 3 is an inner part of the outer casing 2; A locking piece 10 is provided at the tip of the extrusion plate 4, and is connected to the base end 5 of the outer casing 2, the push plate 7 and end wall 8 in the base frame 6, and the connecting piece 9 by freely hanging therefrom. 11a is a spring interposed between the base end portion 5 and the push plate 7 so as to press the push plate 7 backward at all times; 11b is the base frame; The spring 12 interposed between the end wall 8 of 6 and the locking piece 10 extends below the base frame 6. The opening needle-shaped body 14 is provided so as not to be exposed.
and a fulcrum 16 provided above the grip portion 15.
A pin 1 that rotates freely through the pin and is provided near its upper end.
7 and a movable handle 18 formed so as to press the back surface of the lower edge of the push plate 7, and the grip part 15 and the movable handle 18 are formed in a U-shape in cross section with openings on their opposing surfaces;
A movable handle 18 is adapted to fit into the grip portion 15.

The operation will be explained below with reference to FIG. 3. The movable handle 18
When the handle is gripped against the grip part 15 and pulled in the direction of arrow C, the upper end of the movable handle 18 also rotates via the fulcrum 16, and the push plate 7 is bent and tilted like the push plate 7' via the pin 17. Because it is twisted relative to the rod 3,
The rod 3 and the push plate 7 are in a locked state, and as the pin 17 moves forward, the rod 3 also moves forward.

As the rod 3 moves forward, the extrusion plate 4 at the tip presses the rear part of the storage container A loaded in the outer casing 2, causing the filler to be discharged from the nozzle a.

Next, when the movable handle 18 is released from the grip, the pressing force of the push plate 7 is released and the locking state between the push plate 7 and the rod 3 is also released, so that the push plate 7 is moved to the rod by the elasticity of the spring 11a. 3
Step over it and retreat to your old position.

In this case, the locking piece 10 is warped by the elasticity of the spring 11b and is twisted with respect to the rod 3, so that the rod 3 is locked by the locking piece 9 and cannot move backward even if it moves forward. There's nothing to do.

Thus, by operating the moving handle 18, the rod 3 can be moved forward in a wave-like manner.

In order to return the rod 3 to its old position, it is best to push the locking piece 9 forward to release the locking state with the rod 2, and then pull it backward using the handle 19.

When loading the filler storage container A into the caulking gun 1, the nozzle a of the storage container A must be opened in advance. Although there was the inconvenience of having to insert the needle through the nozzle, in the present invention, the opening needle-like body 14 provided in the grip portion 15 of the handle 12 is used.
It is extremely convenient because it can be opened easily by inserting the container A into the nozzle.

Furthermore, since it is integrated with the caulking gun 1, the worker is not put under any mental stress due to preparation before work or dropping it during work, which is useful for improving work efficiency.

Moreover, since the opening needle-shaped body 14 is provided inside the box-shaped grip part 15, it is extremely excellent from the viewpoint of security.

In the above embodiment, the opening needle-like body 14 is attached to the back 1 of the grip portion 15.
3, but it may also be provided on the back of the movable handle 18.
