Description

[Detailed description of the invention] The purpose of this invention is to prevent painted walls from having any marks.

Conventionally, when painting a wall, paint marks occur depending on the amount of force applied to the boundary line between the finished wall and the wall that is to be painted subsequently, so for example, when using a trowel, it is necessary to stroke the entire surface again to make sure there are no uneven surfaces. This is the plasterer's job, and this kind of operation is not efficient. However, this invention is designed to limit the pressure applied to both ends of the spatula tip in order to eliminate these drawbacks.One example of this configuration will be described in detail with reference to the drawings. The proximal end is expanded laterally to form a substantially inverted T-shape, and the expanded portion is formed into a mounting portion A, and a rectangular spatula tip 2 is formed forward from the lower surface of the mounting portion I. Protrude forward. Reference numeral 3 denotes a cutting space, which is formed between the attachment portion A and the attachment portion A by obliquely cutting a portion of the left and right rear edges of the spatula point 2. Reference numeral 4 denotes a spatula tip press plate, which is provided on the upper surface of the spatula tip 2 on the lower surface, and is formed slightly shorter than the spatula tip 2, and the left and right rear edges are cut diagonally in the same shape. It is fixed to the mounting part A, and a slight space 6 is formed between the spatula tip 2 and the spatula tip pressing plate 4. In this case, it is preferable that the spatula tip portion 2 be made of a slightly flexible piece of synthetic resin, for example, and that the spatula tip pressing plate 4 be made of a synthetic resin piece that is slightly harder than the spatula tip member. 5 is a wall coating material.

This idea is structured as above, so
When the wall painting material 5 is attached to the wall surface and applied with the spatula tip 2, the force of the spatula tip 2 is applied at the center, that is, within the straight line area where the handle and the spatula tip 2 are fixed, and the wall material 5 is applied with the spatula tip 2. Although pushed out in the direction of both ends of the tip 2, the cutting space 3 and the spatula tip pushing plate 4 are formed by partially obliquely cutting the left and right rear edges of the spatula tip 2.
In synergy with this, an even pressing force is applied to the spatula tip 2, and the force of the handle is removed, so the waist weakens and the pressing force against the wall material moves away and becomes lighter. By aligning the boundaries between the wall and the wall to be painted, a uniform wall surface is obtained without creating any streaks between the walls.

Effects of the Device As described above, this device has a slight notch 3 inward between the left and right ends of the attachment portion A of the handle 1 and the inner edge R of both the left and right ends of the spatula point 2 attached thereto.
Since the pressure applied to the spatula tip 2 is different in strength between the center and both ends, there is no coating on the wall material, and the appearance is always uniform and beautiful, and even an amateur can easily apply the coating.

Claims (1)

[Scope of utility model registration request] The base end of the handle 1 is thickened to form a laterally expanded attachment part A, and the front edge of a rectangular spatula tip 2 attached to the lower surface of the attachment part I projects forward;
By obliquely cutting a portion of the left and right rear edges of the spatula point 2, a cutting space 3 is formed between the rear edge of the spatula tip 2 and the same shape, which is slightly shorter and shorter, is formed on the upper surface of the spatula tip 2. The front edge of the spatula tip pressing plate 4 is configured in two stages by protruding from the upper surface of the spatula tip 2, and the left and right rear edges of the pressing plate 4 are diagonally cut to separate the spatula tip 2 and the spatula tip pushing plate 4. A spatula is formed by fixing a part of the rear edge of the push plate 4 to the upper surface of the mounting part A so as to form a space 6 therebetween.
