Description

Field of technology.

The utility model relates to the field of construction and is intended for applying and forming a profile of viscous materials such as sealant, mastic, glue, etc.

State of the art.

Among construction spatulas, for example, a silicone spatula for mixing is known (Internet resource https://epoxymaster.ru/raskhodnik/silikonoviy-shpatel-dlya-peremeshivaniya-13/, access date 05/24/2023, [1]). As in the claimed technical solution, this analogue contains a handle with transverse grooves that prevent the spatula from slipping in the hand.

The analogue [1] has a hole at the tip of the handle that allows you to store the spatula hanging.

The disadvantage of the analogue [1] is that the end of the spatula is straight, which makes it inconvenient to apply viscous material to the surface. In this case, the marks are made only on the upper surface of the spatula.

A spatula for applying sealant is also known (CN208742963U “Spatula is glued in aerospace seal”, SUZHOU MIHENG MATERIAL TECH CO LTD, B05C17/10, publ. 04/16/2019, [2]), containing an elongated rod-handle, at the ends of which there are two scraper blades that are curved in opposite directions.

In analogue [2], the heads of the two scraper blades are arched to simplify the process of scraping off the sealant and to ensure that the shape of the sealant after application will correspond to the requirements of the structure.

The disadvantage of analogue [2] is that the surface of the rod is made smooth. In this regard, the spatula slips in the hand during use.

A technical problem, the solution of which is provided by implementing or using a technical solution, is the need to improve the ergonomic characteristics of the spatula in order to fix the working part in a position convenient for work and at the required angle, which allows you to work faster with the material without making corrective movements.

Disclosure of the proposed technical solution.

The technical result provided by the claimed technical solution is to increase the convenience of holding the spatula handle in the hand.

The essence of the claimed technical solution is that the handle of a spatula for working with viscous materials contains a rod section, which is associated with working elements in the form of blades that are curved in opposite directions. It differs in that the rod section contains alternating transverse annular projections and sections with longitudinal projections.

The above essence is a set of essential features of the claimed technical solution, ensuring the achievement of the declared technical result.

In particular cases, it is permissible to implement a technical solution as follows.

There are preferably two annular projections.

The sections with longitudinal projections have a cross-section of a square configuration, with the projections being rounded along the radius, and on each side of the section with longitudinal projections there are three projections.

The transition areas between the handle and the blades are beads that are tapered in the longitudinal direction.

Implementation of a technical solution.

The spatula handle for working with viscous materials (Fig. 1) contains a rod section 1, which is associated with working elements 2 in the form of blades.

The rod section 1 contains alternating transverse annular projections 3 and sections with longitudinal projections 4 (Fig. 2).

There are preferably two annular projections 3.

The sections with longitudinal projections 4 have a cross-section of a square configuration. In this case, the protrusions are made rounded along the radius. On each side of the section with longitudinal projections 4 there are three projections.

The transition areas between the rod section 1 and the working elements 2 are flanges 5 that are tapered in the longitudinal direction.

Each working element 2 has a wedge-shaped shape. In this case, the working elements 2 are bent in opposite directions (Fig. 3).

Each working element 2 has a longitudinal stiffening rib 6 tapering towards the end.

Order of use.

Puttying (local or general leveling of the surface) is performed using viscous compounds (sealant, mastic, glue, etc.) to improve the quality of the surface and prevent possible cracking. In this case, the working elements 2 collect the required amount of viscous material from the container and apply the composition to the treated surface of the wall or ceiling. In this case, the annular projections 3 and longitudinal projections 4 prevent the handle 1 from sliding in the hand.

The claimed technical solution was implemented using industrially produced devices and materials, a prototype of this solution was manufactured, tests of which confirmed the achievement of the technical result.
