Description

Hera for silicon work

The present invention relates to a silicone working spatula, and more specifically, by changing the direction of the two-size spatula part from the handle to be used according to the working conditions, the silicone working spatula is improved to reduce parts due to the assembly of the spatula and the handle. And it relates to a silicone working spatula that improves assembly productivity, converts the direction change of the spatula part into a structure relatively simply, and enables more stable fixed use at the changed position.

In general, as a means for finishing bonding between various building materials (eg, marble, glass, chassis, etc.), an adhesive operation using silicone is widely used.

Silicone (also called 'sealant') is filled with masking tape (paper tape) attached to the surface of marble, a building material, and silicone is injected between marble and marble. At this time, silicone injection is performed by attaching the silicone-filled tube to the silicone gun and pulling the handle so that the silicone filled in the tube is extruded through the outlet to fill the silicone between the marbles.

Then, put on disposable plastic gloves and trim the injected silicone side with your fingers, and when the silicone hardens, remove the masking tape with a sharp razor blade or knife.

The silicone finishing operation as described above takes a lot of time for the operator to manually trim the silicone without a separate tool after the silicone is injected, and the finished surface is not aesthetically pleasing. The finishing work is performed using Hera, which is made of raw rubber or urethane, a soft synthetic resin material, for aesthetically clean silicone work.

Looking at the Hera-related seafarer technology for silicone work, Republic of Korea Patent No. 10-1041007 (name: Hera for silicone work, announcement date: 06/16/2011, hereinafter referred to as 'seonwon draft') is disclosed.

As shown in the attached figures 1 and 2, the seafarer's design is detachably provided on one side of the handle 110 and the handle, and has an arc-shaped inclined spatula 121 of different sizes on both sides of the handle ( In the silicone working spatula 100, which is formed integrally with a trim member 120 for trimming the silicone coated surface, and a fastening member 130 for detachably fastening and fixing the trim member through the handle,

A rotary connector 140 is provided at one end of the handle 110, and is rotatably connected and installed from the rotary connector 140 to change the direction together with the attachment and detachment of the trim member 120. Includes a rotary table 150. It is characterized by

In addition, the rotary connector 140 has a connecting shaft portion 141 having a concave portion 141a in order to be mounted with a snap ring (R) for preventing separation, and a coupling protrusion 142a on the outer periphery of the connecting shaft portion 141 is extended. The formed coupling shaft portion 142, and the coupling shaft portion 142 is composed of a housing 143 to receive and combine in a protruding form.

In addition, the rotary table 150 is a rectangular body with an open bottom surface, a first through hole 151a is formed in the center, and first coupling holes 151b are provided on both sides of the first through hole, and penetrates inside the open bottom surface. A body 151 provided with support jaws 151c to correspond to each other on both sides based on the ball 151a, and a second through-hole matching the first through-hole 151a and the first coupling hole 151b ( 152a), a cover 152 provided with a second coupling hole 152b, and a guide installed parallel to the support jaw 151c of the body 151 to rotate the body 151 about the rotary connector 140 as an axis It is composed of a pair of plate springs 153 that elastically support the angle at an angle of 90 degrees.

That is, the present invention is to provide a silicone working spatula that can be used for each of two types of sizes and can be easily converted and used efficiently.
