Abstract

PURPOSE:To enable a caulking nozzle to be inclined laterally or obliquely by a required angle, and ensure that an object can be properly caulked even in a narrow space by a method wherein a caulking joint to be inserted between a caulking agent container and a caulking nozzle is made of a bend. CONSTITUTION:A caulking joint is inserted between a caulking agent container and a caulking nozzle, In this case, the joint is made of a bend. Namely, a joint of a bending angle of 90 deg. and a joint 11 of a bending angle of 135 deg. are separately prepared. The inner surface of the base end of each of the joints is threaded to have a female screw 15 to be engaged with a male screw on the outer surface of the mouth part of the caulking agent container. The outer surface of the top of each of the joints is threaded to have a male screw 14 to be engaged with a female screw on the caulking nozzle. In this manner, the caulking nozzle can be inclined by an angle of 90 deg. or 45 deg. with respect to the longitudinal direction of the caulking agent container. Therefore, the caulking nozzle can be correctly directed to an object to be caulked even in a narrow working space.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a bending joint for caulking which is inserted between a caulking agent container and a caulking nozzle.

[0002]

2. Description of the Related Art Caulking agents are a type of sizing agent for construction and are used for filling gaps between members and gaps between walls and appliances.

Caulking agents are viscous pasty liquids and are usually supplied in a tube container. When using, cut the tip of the attached caulking nozzle to provide the required opening, attach it to the tube container, press the tip of the nozzle into the gap that is the construction target, and press the tube container to remove the caulking agent. Work by pushing out from the tip of the nozzle.

The length of the commercial caulking agent tube container is usually around 30 cm, and the caulking nozzle attached thereto can be mounted only on the longitudinal axis of the caulking agent container. Since the length of the nozzle is about 6 to 8 cm, the total length becomes about 40 cm when the nozzle is attached to the caulking agent container.

In order to finish the caulking beautifully, the tip of the caulking nozzle must be correctly oriented to the gap to be caulked. However, if the construction area is narrow, the container with a nozzle that has a total length of nearly 40 cm as described above becomes an obstacle and the tip of the caulking nozzle cannot be correctly aimed at the gap to be constructed. Can be difficult or impossible.

When the working area is narrow as described above, it is convenient that the caulking nozzle is inclined laterally or obliquely with respect to the longitudinal direction of the caulking agent container. But conventionally,
No bending nozzle or member for tilting the nozzle has been provided which can meet such needs.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems relating to caulking, and provides means for tilting the caulking nozzle laterally or obliquely by a desired angle as needed. The purpose is to

[0008]

The above object of the present invention is achieved by inserting a bending joint for caulking, which is a bent tube, between a caulking agent container and a caulking nozzle.

In the above joint, the angle of the bent pipe is 90 degrees and 135 degrees (inclination 4 from the joint base axis).
If two types of joints (5 degrees) are prepared, it is practically sufficient.

In the above joint, the ratio of the total length to the outer diameter of the bent pipe is preferably 3 or more and 5 or less. The total length can be distributed to the base straight pipe and the front end straight pipe sandwiching the bent portion at an appropriate ratio.

[0011]

By inserting the bending joint for caulking according to the present invention having a predetermined bending angle between the caulking agent container and the caulking nozzle, the direction of the caulking nozzle can be inclined laterally or obliquely by that angle. This makes it possible to correctly orient the tip of the caulking nozzle to the gap to be caulked even when the construction site is narrow.

In this case, it suffices that the tip of the caulking nozzle is approximately correctly oriented to the gap to be caulked, and even if the construction site is narrow, the attitude of the caulking agent container can often be adjusted to some extent. Therefore, if the predetermined bending angle is 90 degrees or 135 degrees, it is practically sufficient.

If the total length (the total length measured on the central axis) of the above-mentioned bending joint for caulking is too long, it becomes a hindrance to the object of the present invention. If the length is too short, the lengths of the upper and lower screw portions cannot be secured. Therefore, 3 times the outer diameter is the minimum length, and 5 times or less is the reasonable length. In addition, even with curved joints with the same total length,
Various types of joints having different usability can be prepared depending on the ratio of the straight pipe length at the base portion and the straight pipe length at the distal end that sandwich the bent portion.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a commercially available caulking agent container 1 (see FIG. 1).
a) and the caulking nozzle 2 attached to it (see FIG. 1).
It is a structure explanatory view of b). Mouth 3 of caulking agent container 1
Is provided with a male screw 4 that is screwed to the storage cap and the caulking nozzle 2, and a female screw 5 that is screwed to the male screw 4 is provided inside the base of the caulking nozzle 2.

FIG. 2 is a structural explanatory view of the bending joint for caulking according to this embodiment. 2a shows the joint 10 with a bending angle of 90 degrees, and FIG. 2b shows the joint 11 with a bending angle of 135 degrees.
Both of them are provided with a female screw 15 which is screwed to the male screw 4 on the inner side of the base and a male screw 14 which is screwed to the female screw 5 at the tip.

The inner and outer diameters of the caulking bending joints 10 and 11 are naturally determined by the screws 14 and 15. In addition, the total length of the bent joint should be 3 times or more and 5 times or less of the diameter, and various total lengths and the ratio of the length of the base straight pipe / the length of the straight pipe at the tip can be selected according to the situation of the construction site It is desirable to prepare joints with different types.

The caulking bend joint according to the invention can be made of metal or plastic. In the case of metal, an aluminum cast product can be used, for example. In the case of plastic, a thermoplastic resin such as polyethylene or vinyl chloride is preferable from the viewpoint of easy molding. The bending joints 10 and 11 for caulking of this example were made by cutting and joining commercially available hard vinyl chloride pipes.

The operation of the bending joint 10 or 11 for caulking constructed as described above is as follows.

That is, the female screw 15 is screwed into the male screw 4, and the bending joint 10 or 1 for caulking is provided.
1 is fixed to the mouth portion 3 of the caulking agent container 1, and the male screw 14 is screwed into the female screw 5 to fix the caulking nozzle 2 to the tip of the bending joint 10 or 11 for caulking.

By doing so, the caulking nozzle 2
90 ° with respect to the longitudinal direction of the caulking agent container 1.
It can be tilted in degrees or 45 degrees.

As a result, as shown in FIG. 3 (a), since the caulking portion is narrow, if the caulking nozzle 2 is directly attached to the caulking agent container 1, the tip of the nozzle should be correctly directed to the gap to be treated. Even when it is not possible, the bending joint 10 or 1 for caulking according to the present embodiment
1 is used to adjust the direction of the caulking nozzle 2 and, as shown in FIG.
The tip of the can be correctly pointed in practice toward the gap to be constructed.

[0023]

By using the bending joint for caulking according to the present invention described above, the angle of the caulking nozzle is adjusted so that the tip of the nozzle is correctly directed to the gap to be constructed even when the location of the caulking is narrow. It will be possible. As a result, caulking work can be performed efficiently and a beautiful finish can be obtained.
