Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint sealing primer applicator mainly used for applying a primer to joints between outer wall panels of a building.

[0002]

2. Description of the Related Art When sealing is applied to joints between outer wall panels, a primer applied to the joints prior to the sealing plays an important role in ensuring the performance of the sealing to be applied thereafter. This primer application work is carried out by opening a special can containing the primer, transferring it to a container on hand, and applying it to the mouths of the outer wall material on the left and right of the joint with a brush.

[0003]

Generally, most of the joints to which the primer is applied are vertical joints which are vertically continuous.
Since the left and right recesses of the surface material to be applied are hard to see from the outside, it is often necessary to rely on intuition to apply the primer.

For this reason, the coating accuracy of the primer depends on the skill of the operator, and sometimes it is easy to forget to apply the coating or the coating unevenness occurs. Depending on how the brush is applied, the primer may drip from the brush and spread around the area. Staining happens. Since a container with a wide mouth, which has a large contact area with air, is used as the container on hand, the solvent is easily volatilized and the primer is easily deteriorated.

Further, since the primer application work is carried out many times while putting it in the container and reattaching the primer to the brush,
At that time, the foreign matter adhering to the joints easily mixes from the brush to the primer in the container, and the primer may spill out from the container during the work, or the brush will continue to repeat unless it is properly cleaned after the work. Trouble such as being unable to use easily occurs.

EXAMPLES The present invention will be specifically described below with reference to the illustrated examples. FIG. 1 is a cross-sectional side view of the joint sealing primer applying device 27, and the primer discharge pipe 13 is formed by joining an outer discharge pipe 28 and an inner discharge pipe 29 at the root of the lid 12. The brush 15 is formed in a tubular shape so as to surround the discharge port 30, and is detachably screwed to the tip 14 of the outer discharge pipe. A coil spring 23 is inserted in the inner discharge pipe 29, and the coil spring 23 allows the spherical body 24 to be always in light contact with the peripheral edge of the circular hole 17.

An elongated bolt is used for the connecting rod 21. The connecting rod 21 has a hole 3 formed at the tip of the lever 22.
It is loosely fitted in 4, and the tip is a bolt head,
It does not come off from the hole 34. The connecting rod 21 projects through a hole 36 formed in the lid 12 and projects into the interior of the primer storage container, and the projecting portion is fitted into the coil spring 23 and projects through. A guide piece 31 is attached to the upper end of the sheath pipe 18, and a connecting rod 21 is loosely fitted into a hole 32 bored in the guide piece 31 and pierces through. A nut 33 is attached to the lower end of the piercing connecting rod 21. Is screwed, and the nut 33 is used to connect the connecting rod 2 from the hole 32.
It is stopped so that 1 does not come off. Coil spring 2
3 is compressed by being sandwiched between the lid 12 and the guide piece 31,
The sheath tube 18 is elastically urged by the coil spring 23 in the direction of coming out of the inner discharge tube 29.

A packing 35 is attached to the back side of the lid 12 to prevent leakage of the primer 37 from the primer storage container. The lever 22 is bent in the vicinity of the hole 34, and when the rear end 38 is pressed, the hole 34 is lifted with the bent corner as a fulcrum 39. In the figure, 40 is a handle for holding the primer storage container 11.

Stainless balls are used for the spheres 24 and 25, and the stainless balls 24 in the inner discharge pipe are in a normal state with the tip 14 of the outer discharge pipe 28 facing upward.
Is the circular hole 1 at the tip of the mouth due to its own weight and the coil spring 26.
The stainless steel balls 25 in the sheath tube are in close contact with the inner peripheral edge of the circular tube 20 at the mouth end of the sheath tube by its own weight.

[0011]

When the rear end 38 of the lever 22 is pushed, the hole 34 is pushed up, the sheath tube 18 is pulled up through the connecting rod 21, and the gap between the tip 19 of the sheath tube and the tip 16 of the primer discharge tube is increased. The pressure in the sheath tube 18 increases due to the narrowing. as a result,
As shown in FIG. 2, the elevated pressure in the sheath pipe 18 pushes up the stainless ball 24 in the primer discharge pipe to open the circular hole 17, and the primer 37 in the sheath pipe passes through the circular hole 17 to the primer discharge pipe 13. The primer 37 is discharged from the discharge port 30 of the inside 15 of the brush as it enters.

On the other hand, when the rear end 38 of the lever 22 is loosened, the connecting rod 21 and the sheath tube 18 are pushed down by the coil spring 23, and the space between the mouth 19 of the sheath tube and the mouth 16 of the primer discharge tube is widened to allow the inside of the sheath tube 18 The pressure drops. as a result,
As shown in FIG. 3, the stainless steel balls 25 in the sheath pipe are pushed up by the pressure of the primer storage container 11 having a higher pressure than that in the sheath pipe 18 to open the circular hole 20, and the primer in the primer storage container passes through the circular hole 20. 37 will enter the sheath tube 18.

After that, when the rear end 38 of the lever 22 is pushed, the primer 37 in the sheath pipe again passes through the primer discharge pipe 13 and is discharged from the discharge port 30. The operation of the rear end 38 of the lever 22 can be performed by grasping the handle 40, holding the primer storage container 11 in one hand, and using the thumb.

[0014]

As described above, according to the present invention, the rear end 38 of the lever 22 is operated by the thumb of one hand holding the primer storage container 11, and the primer 37 from the brush 15 at the tip is operated.
The amount of discharge of the primer 37 and the amount of the primer 37 attached to the brush 15 can be adjusted by adjusting the lever 22 with the thumb. Disappeared,
The primer 37 does not drip from the brush 15.

During the primer coating operation, the primer 37 is only discharged from the primer storage container 11, and the brush 15 is not put in the primer storage container 11. No foreign matter enters into the primer storage container, and the primer 37 in the primer storage container is kept in a clean state.

Since it is not necessary to open the lid 12 of the primer storage container 11 until the primer 37 is used up,
