Description

Spatula cutter for wallpaper

The present invention not only can be used as a spatula to adhere the wallpaper without including air between the base when applying the wallpaper, but also uses a ruler near the wall, near the ceiling, near the floor, etc. With regard to the wallpaper spatula cutter, which can cut the pasted wallpaper easily, quickly and cleanly, in particular, it is possible to easily put in and out the necessary amount of the cutter blade, and has excellent safety and workability. It relates to a spatula cutter.

Conventionally, when pasting wallpaper on indoor walls, etc., a spatula called territory is used to attach the wallpaper in close contact with the base, without containing air. If it is necessary to cut by reaching the corner of the wall, etc., move the spatula along the corner, fold the wallpaper at a right angle, crease it, and then fix the ruler with one hand. The other hand with the cutter was moved along the ruler, the wallpaper protruding from the ruler was cut by the length of the ruler, the ruler was moved, and the work of cutting again was repeated. This series of operations is not only cumbersome, but also has the drawback of requiring many years of skill to make the cut seam as smooth as a continuous cut.

Therefore, a cutter knife having a cutting blade guide function suitable for cutting a sheet affixed to one of two planes orthogonal to each other along the intersecting line of the two planes (patent) Reference 1) was proposed. However, although this cutter knife can cut the sheet by one-handed work, it has a structure in which the cutting blade is extended from the center of the guide mechanism, so the sheet cannot be folded into the corner sufficiently and the corner is full. However, it was difficult to finish it cleanly.

The above-mentioned drawback is that a blade that can be taken in and out at one end of a guide surface having a guide that can be folded into the cross by pressing the cross against the corner, and moving the guide surface along the corner This was improved by a cutter (Patent Document 2) that can cut the cloth with one hand. In the case of this cutter, although the folding of the cloth is improved, the guide plate and the blade sheath overlap, and the blade protrudes from the sheath, which corresponds to the thickness of the guide plate and the sheath. If the wallpaper of the width remains on the wall side perpendicular to the wall where the wallpaper is pasted, or if it is cut on the surface where the wallpaper is pasted, it will not be possible to paste the wallpaper across the corner and avoid being short. Can not. In addition, if the remaining folded portion remaining as described above is not glued properly, there is a disadvantage that it may cause peeling at a later date, and the fixing of the blade is a screw that presses the back of the blade, Since this is done by biting the blade into the tip of the sheath, there is a drawback that blade spillage is likely to occur.

The above disadvantage is due to a sheet cutter (Patent Document 3) that is provided with a cutter knife blade and a guide plate that swings about an axis in the main body and can be cut with the sense of a fingertip without being influenced by the direction of light or illuminance. Improved. However, in the case of this sheet cutter, the guide plate easily rotates around the axis, so that the operation stability of the guide plate is insufficient. In order to cut cleanly, not only skill is required, but the angle between the blade protruding from the guide plate and the wallpaper to be cut is small, so there is a drawback that the sharpness is poor.
Moreover, these conventional cutters cannot be used together as a spatula, and it has not been possible to improve at all about the point that a spatula and a cutter must be prepared separately.

As a result of intensive studies to improve the conventional drawbacks as described above, the present inventor has developed a fixed plate that functions as a wallpaper ground spatula in a crescent shape (which can be said to be a saddle type, but is unified in this specification). In addition, a crescent-shaped cutter (which can be said to be a saddle type, but unified in a crescent shape in this specification) is rotatably combined with both ends of the spatula portion of the fixing plate. As a result, it can be safely used as a ground spatula when the blade of the cutter does not protrude from the fixed plate, and at the corner portion of the wall, while folding the wallpaper into the corner with the fixed plate, By projecting a predetermined amount of the blade of the cutter from the back end of the spatula, which is the back end with respect to the moving direction, the wallpaper can be cut beautifully with one hand along the corner. Have reached the present invention found Rukoto.

Accordingly, a first object of the present invention is to provide a wallpaper spatula cutter that can be used as a safe ground spatula and a cutter and can be operated with one hand.
A second object of the present invention is to provide a spatula cutter for wallpaper that can cut affixed wallpaper safely, promptly and beautifully without using a ruler at a wall, ceiling, or floor. There is to do.

The above-mentioned objects of the present invention are to provide a fixed plate which functions as a ground plate made up of a semicircular or less partial circular plate and a spatula portion extending to the tip of the plate, and an inner wall surface rising from an arcuate end of the fixed plate. A cutter blade having an arcuate outer edge that can be rotated while sliding on the blade, and a blade that cuts the wallpaper can be inserted into and removed from the edge of the spatula portion of the fixing plate and can be stored and fixed in an interchangeable manner. The rotation type cutter part which has the outer edge and is made of a partial circular plate smaller than the fixed plate, and further has an operation lever as appropriate, without hindering the spatula function of the spatula portion of the fixed plate. The spatula cutter is a spatula cutter in which the cutter part is rotatably combined with respect to the fixed plate within a range of 10 ° to the left and right, and the cutter unit is operated with respect to the fixed plate by operating the operation lever. Either left or right The end of the partial circular plate of the cutter part is cut out in advance so that the tip of the cutter blade can be brought out at the tip of the spatula part by rotating, and the cutter blade is stored and fixed so that the cutter blade is inclined. Achieved by a spatula cutter for wallpaper, characterized in that.
In the present invention, the maximum rotation angle of the cutter with respect to the fixed plate is preferably 7 °, and it is preferable that the cutter can be easily rotated to the maximum rotation angle. The length of the spatula portion of the fixing plate in the longitudinal direction can be appropriately designed in the range of 20 to 25 cm, and the width in the short side direction is in the range of 1 to 10 cm. Moreover, the size of the partial circular plate portion equal to or less than a semicircle corresponding to the outer circular portion of the fixed plate can be appropriately designed within a range where it can be easily grasped by hand.

The spatula cutter for wallpaper of the present invention can usually be safely used as a ground spatula, and when it reaches the corners such as near the wall, ceiling, and floor, it folds the wallpaper at the corner with the spatula, then You can easily cut the wallpaper so that it fills the corner while moving the cutter blade along the corner. In addition, since all the operations can be performed with one hand, workability is extremely good, and even if the skill level is low, it can be finished satisfactorily.

Hereinafter, the present invention will be described based on examples, but the present invention is not limited thereto, and wallpaper obtained as a result of design changes usually made by those skilled in the art based on the present specification and / or the accompanying drawings. Spatula cutters are also included in the concept of the present invention.

FIG. 1 is a photographic substitute perspective view of the upper surface of a spatula cutter for wallpaper according to the present invention, which is designed so that the rotation of the cutter part with respect to the fixing plate 10 (see FIGS. 2 and 3) is 10 ° to the left and right. . In the figure, reference numeral 1 denotes a cutter blade, 2 denotes a storage and fixing portion of the blade, and the side 3 accepts a known means 3 for adjusting the cutter blade loading and unloading and locking, corresponding to the cutter blade folding unit. It has a corrugated structure 4. Reference numeral 11 denotes a spatula portion in the fixed plate 10.

Reference numeral 5 denotes a lever for moving the crescent-shaped cutter portion along the arc of the partial circle of the fixing plate 10 having a crescent-shaped partial circular portion, and the partial circular portion of the fixing plate 10 of the lever; The overlapping central portion is provided with a concave portion 6 for receiving the convex portion 13 provided in the central portion of the partial circular portion of the fixing plate. In this embodiment, this lever is one lever, but it may be composed of two levers, or may be covered with a cover having an appropriate shape in order to improve workability and appearance. Further, this lever can be manufactured separately from the partial circular plate of the cutter portion, and can be processed and fixed to the partial circular plate of the cutter portion by a known means such as a screw or an adhesive. Depending on the shape of the handle or the fixing plate, it can be integrally formed with the partial circular plate of the cutter portion.

In this embodiment, the outer circular wall 12 standing at the outer edge of the fixed plate has a flange 14 and an opening 15 for enabling the lever 5 to rotate. The bottom surface connected to the opening 15 may be cut out so as to substantially correspond to the width of the flange 14 in order to lighten the rotation of the cutter portion. The convex portion 13 is provided by projecting a metal rod inserted from the upper part by about 1 mm on the inner side (lower side) of the heel center and processing the tip to a round shape. As a result, when the cutter portion is not operated, the convex portion 13 can be fitted into the concave portion 6 so that the cutter can be controlled not to rotate freely. This control means is an example, and it is designed to control the unintended rotation of the cutter unit using a spring or the like, or controls the unintended rotation of the cutter unit by a known method such as combining them. Of course, it is okay.

In the present invention, the outer circle of the fixed plate is operated in order to rotate the partial circular cutter portion with respect to the fixed plate (see FIGS. 2 and 3) having the outer circular wall 12 by operating the lever. The wall 12 is provided with an opening 15 of a desired length for projecting the handle and operating it along the arc (see FIGS. 4 and 5). However, when the sliding surface of the fixed plate and the cutter portion becomes large Since the turning operation becomes heavy, it is preferable to appropriately cut or cut the sliding portion in order to reduce the sliding area and lighten the turning operation. Also in this embodiment, a part of the arc of the partial circular cutter part is cut out (see FIGS. 6 to 8), and a part of the bottom surface is cut out in addition to the opening of the fixing plate (see FIG. 6). These are examples for reducing the sliding area. The present invention is not limited to these methods, and can be designed as appropriate.

For example, a rail is provided on either the cutter portion or the fixed plate of the present invention, and a slidability is provided by a method such as providing a roll that can be freely rotated on the rail, or interposing a sliding sheet. Can also be improved. In addition, a cover can be provided around the lever to improve the appearance and ease of holding, but it is natural that the cover may be designed to be easily held without a cover.

In the present invention, when the cutter part is rotated or as a result of the rotation, a part of the cutter part may protrude from the spatula part, so that at least the protruding part is notched in advance. There is a need. Note that the spatula portion is usually rectangular, but can be appropriately designed within a range that does not hinder the use as a ground spatula, such as a trapezoidal shape.

A commercially available blade can be used as the blade of the cutter of the present invention. The blade insertion / removal and fixing means may be well-known means used for commercially available cutters. In this case, since it is necessary to remove the adjusting means 3 when exchanging the blade of the cutter, a deep recess 7 may be provided on the extension line of the cutter blade storage fixing portion (see FIG. 7). However, the cutter blade stored in the storage fixing portion needs to protrude from the tip of the spatula portion so that the wallpaper can be cut in cooperation with the spatula portion after being pushed out of the storage fixing portion. And it accommodates in an accommodation fixing | fixed part so that an appropriate angle may be formed with respect to a fixing plate.

In this way, the thickness of the cutter storage fixing portion is thinner near the blade edge of the cutter, so far away from the blade edge, the portion such as the deep recess 7 portion that does not affect the cutter blade is thickened on the contrary, About such a part, the increase in thickness can also be suppressed. In this case, the deep recess 7 may not be provided or may be a shallow recess according to a design that suppresses an increase in thickness.
If an increase in unnecessary thickness is suppressed, not only can the spatula cutter of the present invention be lightened to improve operability, but also material costs can be reduced.

In order to cut the wallpaper neatly using the spatula cutter of the present invention, the cutter blade must not rattle or bounce during use. In order to prevent such a phenomenon, in the present invention, it is necessary to design the cutter blade that has reached the tip of the spatula portion from the cutter portion so that it can be in close contact with the tip of the spatula portion at least during use.

In the present invention, it is necessary to design the angle of the cutter at the time of wallpaper cutting so that the wallpaper can be reliably cut by the cutter blade protruding from the tip of the spatula portion. In the present invention, the angle of the cutter blade with respect to the tip of the spatula portion in use is in the range of 100 ° to 170 °, particularly 110 ° to 160 °, with respect to the cut direction (longitudinal direction of the spatula portion). It is preferable to design so that it may become a range. Also, the distance from the spatula part to the tip of the cutter blade (the length of the perpendicular line extending from the cutter blade tip to the tip of the spatula) is designed to be about 1 to 3 mm, depending on the thickness of the wallpaper. It is preferable to do.
In the present invention, it is preferable to satisfy the above requirements when the rotation of the cutter portion is set to the maximum angle in order to improve the workability of the spatula cutter of the present invention.

The spatula cutter for wallpaper of the present invention can usually be safely used as a ground spatula, and when it reaches the corners such as near the wall, ceiling, and floor, it folds the wallpaper at the corner with the spatula, then Because the wallpaper can be easily cut so that the wallpaper fills the corner while moving the blade out along the corner, the workability is good, and it can be finished well enough with a short experience. It is extremely effective in industry.
