Description

  The present invention relates to a spatula used for clay work, kneading of adhesives, putty, etc., and more specifically, it can be transformed into various forms and at the same time, it retains its shape during use, that is, it produces a shape memory effect. Is related to the improved spatula.

  Conventionally, various spatulas have been used as tools used for coating operations such as adhesives and putty. As this type of conventional spatula, for example, as in Japanese Utility Model Application Laid-Open No. 06-064775, there is one composed of a hard grip portion such as a wooden member and a flexible spatula member such as a steel plate. The portion is formed so as to be elastically deformable, and becomes appropriate when the coated surface is finished smoothly. Further, the whole made of synthetic resin has a hard gripping member at the base end portion and similarly has a flexible flat spatula member at the tip end portion. (See Patent Document 1)

At this time, the flexibility of the tip is an important factor for smoothing the leveling work.

Further, in this main spatula, there is known an improved shape or the like of a member configured in consideration of various workability. In the previous example, the gripping part is deformed according to the degree of gripping. Are known. (See Patent Document 2)

Problems that the device tries to solve

  However, the spatula formed by the above method is deformed, but the tip edge of the spatula member is linear. There is a problem in that the amount of the paint or putty with respect to the coating area is kept, and the paint or putty overflows from both ends, resulting in a liquid pool.

Means for solving the problem

  The present invention has been made to solve such problems related to the conventional spatula. First, a flexible flat spatula member having flexibility and a base end portion of the spatula member are extended. The spatula member is provided with a core member that maintains the curved state of the spatula member in the width direction on the base end side of the spatula member.

  The spatula configured as described above can be curved in a substantially U shape with respect to the coating direction by the shape of the core material, in particular, the previously curved shape, so that paint or putty overflows from both ends. Can be prevented.

  Moreover, said core material concerning this invention is comprised so that attachment or detachment is possible with respect to the groove | channel provided in the surface of the spatula member. By comprising in this way, it is possible to change the curvature rate of a spatula suitably according to a user's use. In the embodiment of the present invention, the core material is composed of a rod-like metal member or a plate-like metal member that is not easily deformed by a normal coating operation.

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

  FIG. 1 is a front view of a spatula according to a first embodiment of the present invention, FIG. 2 is a side view of the spatula according to the first embodiment of the present invention, and FIG. 3 shows a curved state of the spatula according to the present invention. FIG. 4 is an explanatory view of the core material used for the spatula of the first embodiment of the present invention, and FIG. 5 is an explanatory view of the state of use of the spatula of the first embodiment of the present invention. FIG. 6 is a side view of the spatula of the second embodiment of the present invention.

  As described above, the spatula 1 of the present invention can be used for viscous kneading such as adhesives and putty, and can be applied to all spatulas used by school children for clay work. As shown in FIGS. 1 to 6, the spatula 1 shown in the embodiment includes a flat spatula member 2 made of a hard member capable of elastic deformation such as plastic and having an inverted trapezoidal width, and the spatula. It is comprised with the holding member 3 of the same material attached to the member 2 and extended integrally to the slightly hard base end part 2a.

  The spatula member 2 has a substantially trapezoidal shape, and is used by pressing the tip edge against a work target. For this reason, the material of the spatula member 2 and other members may be different, but in order to maintain an appropriate texture, the whole is made of the same material, and the hardness is adjusted by the thickness of each part. It doesn't matter. In the embodiment of the present invention, the spatula member 2 is more flexible in view of the shape retaining property of the portion to which the core member is attached, and the base end portion 2a that supports the spatula member 2 is a member that is slightly harder than that.

  The base end portion 2a for extending the gripping member 3 of the spatula member 2 is formed with a substantially circle-shaped groove 5 lacking the upper end portion in the width direction. 2. More specifically, a cylindrical metal core member 4 is provided in which the base end 2a can be held in a fixed shape.

  As shown in FIG. 2, when the metal core 4 is a cylindrical rod-like body, the groove 5 has a substantially circle-shaped cross section in which the upper end is opened with a width that allows the core 4 to be press-fitted. It is a groove. On the other hand, as shown in FIGS. 4 (a) and 4 (b), the core material 4 is a straight cylindrical metal member that is previously curved in a predetermined shape, and is used in a predetermined bending direction. Then, press-fit into the groove 5 and set.

  In the second embodiment of the present invention, as shown in FIG. 6, the core member 4 is formed of a long rectangular plate. In addition, although not shown in the figure, it is possible not only to bend at one place but also to bend shape at a plurality of places or use a plurality of core materials to stabilize shape retention or to deform more complex spatula shapes. Is also possible.

  In order to perform application and leveling operations of adhesive, putty, etc. on a predetermined application surface using the spatula 1 of the present invention, first, the gripping member 3 is gripped with one hand while the tip edge 21 of the spatula member 2 is predetermined. Apply lightly while pulling in the direction of. At this time, as shown in FIG. 4, the spatula 1 is curved and deformed in advance, so there is no fear of leakage of paint or putty from both ends, and it is possible to perform a beautiful finish without requiring skill. It is.

  Further, in the present invention, the spatula having the outer shape as in the embodiment is used, but it goes without saying that the design change of the outer shape of the spatula can be freely performed as necessary.

Effect of device

  The spatula of the present invention comprises a flexible flat spatula member having an appropriately shaped width and a gripping member extending to the base end of the spatula member, and the base end side of the spatula member extends in the width direction. Since the core material that maintains the curved state of the spatula member is built in, the tip of the spatula member is curved and held during the application work, so work in leveling work, etc. It is possible to perform the work beautifully without requiring skill for the worker and without overflowing paint and putty. In addition, since the core material related to the shape of the spatula of the present invention can be freely attached to and detached from the spatula member, the metal core material is removed and bent by a strong force such as a machine tool or a hand in some cases. This is an epoch-making device that has a wide range of applicability, such as the ability to adjust the shape of the spatula by attaching the core material again, and the manufacturing process is simple, realizing low cost.
