Description

[Technical field]

[0001] The present invention relates to a scraper. More specifically, the present invention relates to a scraper that can be suitably used in special cleaning sites. [Background technology]

[0002] Generally, scrapers (spatula-type scrapers) have a flat spatula-like part at the tip of the handle. These scrapers are used for a variety of purposes, such as removing stickers, applying paint evenly, and removing stubborn dirt (Patent Documents 1 and 2).

[0003] By the way, scrapers are one of the most important tools in special cleaning sites. In other words, at the scene of special cleaning, various things that would not normally be expected remain, such as decomposed and fallen skin, runaway putrefactive fluids and blood, fallen hair, etc. Furthermore, these leftover items are often strongly attached to floors, tatami mats, concrete, etc., making them difficult to remove.

[0004] [Patent Document 1] Utility Model Registration No. 3186988 [Patent Document 2] Utility Model Registration No. 3228521 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0005] The inventor felt that there were issues with using scrapers, which are commonly used as conventional technology, in special cleaning sites. That is, in order to maintain the safety and hygiene of workers at special cleaning sites, it is essential to wear not only masks but also gloves. In such a situation, when removing strongly stuck residue with a scraper of the conventional technology, it is necessary to grip the handle part firmly and apply the spatula part firmly against the stuck residue to scrape it off. However, workers do not necessarily have a strong grip, and there is a problem that they are unable to transfer force effectively to the left behind objects. Also, even if they have a strong grip, the repeated removal of left behind objects gradually weakens their hands, resulting in inefficient work.

[0006] In light of the above circumstances, the present invention aims to develop a scraper that can be used efficiently in special cleaning sites. [Means for solving the problem]

[0007] After extensive research, the inventor came up with the idea of ​​a scraper that is easy to hold, allows force to be effectively transmitted to the spatula part, and is easy to clean by equipping the handle of the scraper with a rotatable (pivotable) guard member and making this removable, and thus completed the invention.

[0008] The present invention comprises the following configuration. [1] A scraper comprising a spatula member, a guard member, and a fixing member, wherein the spatula member has a spatula portion at the tip of a gripping portion and a screw portion at the other end corresponding to the fixing member, and the guard member has a screw hole corresponding to the screw portion, and the guard member is inserted into the screw portion through the screw hole and fixed by the fixing member, thereby allowing the guard member to be fixed at any angle relative to the gripping portion. [2] A scraper as described in [1], wherein the guard member is composed of a single member having three sides, first to third sides, the first side having a screw hole, a second side formed continuous with the first side and approximately perpendicular to the first side, and a third side formed continuous with the second side and approximately perpendicular to the second side. [3] A scraper as described in [2], wherein the guard member further has a fourth edge that is formed continuously with the third edge and is approximately perpendicular to the third edge. [4] A scraper as described in [1], having a recess on the front, back and / or left and right sides at the base of the spatula part of the grip. [5] A scraper as described in [1], in which the spatula members are configured as symmetrical members with symmetrical front and back faces. [6] A scraper described in any of [1] to [5], all of whose components are formed from chemical-resistant metal material. [7] A scraper as described in [6] intended for use in special cleaning sites. Effect of the Invention

[0009] The present invention makes it possible to provide a scraper that can be used efficiently in special cleaning sites. [Brief description of the drawings]

[0011] The scraper of the present invention will now be described. The scraper of the present invention is a scraper consisting of a spatula member, a guard member, and a fixing member, in which the spatula member has a spatula portion at the tip of the gripping portion and a screw portion at the other end corresponding to the fixing member, the guard member has a screw hole corresponding to the screw portion, and the guard member is inserted into the screw portion through the screw hole and fixed by the fixing member, allowing it to be fixed at any angle relative to the gripping portion. This invention enables the user to hook (or pinch) the guard part with their fingers while holding the grip part. This allows the user to press the spatula by putting their weight on the guard part without using much grip strength, making it possible to efficiently apply force to the remaining objects to be removed. Furthermore, since the scraper of the present invention can be easily disassembled into the spatula component, guard component, and fixed component, after use the components can be washed and disinfected by, for example, immersing them in a chemical solution, making it possible to maintain an extremely clean and hygienic condition. Furthermore, since the guard member functions as a member for protecting the fingers, it is possible to improve the safety of the scraper of the present invention.

[0012] In the present invention, the spatula member has a spatula part at the tip of the grip part and a screw part at the other end, and is the part that plays the main role as a scraper. The spatula member does not need to be particularly limited as long as it has such a configuration and plays the main role as a scraper, and can be of various shapes and sizes. The spatula member may typically be configured as shown in Figure 3, with a gripping portion having a certain thickness that makes it easy to grip, a spatula portion having a certain width and length that takes into consideration work efficiency, and a screw portion. In the present invention, it is preferable that the spatula member is symmetrical on both sides, and the front and back are symmetrical. This allows the guard member to be fixed without worrying about the orientation when using the scraper of the present invention, and the feeling of use does not change even when the scraper is used with the front and back reversed, which has the effect of improving the ease of handling and functionality of the scraper of the present invention.

[0013] The length of the gripping portion may typically be 10 to 20 cm, preferably 10 to 18 cm, more preferably 10 to 16 cm, and most preferably 11 to 16 cm. Furthermore, the width of the gripping portion at its widest point can typically be 3 cm to 5 cm, preferably 3 cm to 4.8 cm, more preferably 3 cm to 4.5 cm, and most preferably 3 cm to 4.3 cm. Furthermore, the thickness of the gripping portion can typically be 1.5 cm to 3.0 cm, preferably 1.5 to 2.8 cm, more preferably 1.5 to 2.6 cm, and most preferably 1.5 to 2.4 cm.

[0014] It is preferable that the gripping part has a recess on the front, back, left and right sides near the base of the spatula part. This makes it possible to place the thumb on the recess, making it easier to hold and transmit force when using the scraper of the present invention, which has the effect of improving the ease of handling and functionality of the scraper of the present invention. Such recesses may be provided, for example, on the front and back or on the side as shown in FIG. The recesses on the front and back need only be shaped so that the thumb can be easily placed thereon, and may be of various shapes such as polygonal, triangular, circular, elliptical, etc., although a triangular shape is preferable. The side recess can be in a variety of shapes as long as it is easy for the thumb to rest on, but typically it is in the shape of a circular arc.

[0015] The width of the spatula portion at its widest point may typically be 13 cm to 20 cm, preferably 13 cm to 18 cm, more preferably 13 cm to 16 cm, and most preferably 14 cm to 16 cm. Furthermore, the length of the spatula portion can typically be from 9 cm to 13 cm, preferably from 9 cm to 12.5 cm, more preferably from 9 cm to 12 cm, and most preferably from 9.5 cm to 12 cm.

[0016] In the present invention, the screw part is provided on the distal end side of the grip part (the end opposite the spatula) and serves to fix the card member. The screw part does not need to be particularly limited as long as it serves to fix the card member, and can have various configurations. The screw portion may typically be a cylindrical screw as shown in Figure 3 and may typically have a length of 13 to 20 mm, preferably 13 to 19 mm, more preferably 14 to 19 mm, particularly preferably 14 to 18 mm, and most preferably 15 to 18 mm. The width of the threaded portion may typically be 3 to 8 mm, preferably 3 to 7.5 mm, more preferably 3 to 7 mm, particularly preferably 3 to 6.5 mm, and most preferably 3 to 6 mm.

[0017] In the present invention, the fixing member may be configured as a member having a screw hole corresponding to the screw portion. The fixing member may typically be a cap-shaped member having a screw receiver in the center as shown in Figs. 2 to 8.

[0018] In the present invention, the guard member has a shape like a guard, and serves to make it easier to put weight on it by hooking or pinching the fingers. In addition, it serves as a guard to protect the fingers. The guard member need not be particularly limited as long as it fulfills the above-mentioned role, and various shapes can be adopted.

[0019] It is preferable that the guard member be composed of a single member having three sides, first to third, with the first side having a screw hole, a second side formed continuous with the first side and approximately perpendicular (vertical, or an angle having a certain width that can be functionally regarded as the same as vertical), and a third side formed continuous with the second side and approximately perpendicular. This enables the guard member to fully fulfill its role and makes it easier to form the guard member, thereby improving cost-effectiveness while fully demonstrating the functionality of the scraper of the present invention.

[0020] The first side of the guard member has a screw hole for inserting the screw part through. In addition, the lengths of the first side to the third side determine the distance from the grip part to the second side, so that the first side to the third side can be long enough to allow a finger to fit between the grip part and the second side. The first side may be typically 4 to 10 cm, preferably 4 to 9 cm, more preferably 4 to 8 cm, particularly preferably 4 to 7 cm, and most preferably 4 to 6 cm, taking into account a length sufficient to accommodate the fingers. The first side may have a screw hole near the end opposite to the connection with the second side. The screw hole may be a screw hole corresponding to the screw part of the grip part, and may typically have a circular shape, with a diameter of 3 to 10 mm, preferably 3 to 9 mm, more preferably 4 to 9 mm, particularly preferably 5 to 9 mm, and most preferably 5 to 8 mm.

[0021] The second edge of the guard member functions as the main edge to guard the fingers, and may be configured to have a length equal to or shorter than that of the gripping portion. The second side may be typically 8 to 15 cm, preferably 8 to 14 cm, more preferably 8 to 13 cm, particularly preferably 8 to 12 cm, and most preferably 9 to 12 cm, taking into account a length equal to or shorter than that of the gripping portion.

[0022] The third side of the guard member serves to guard the fingers and to improve the ease of holding the device by pinching the fingers. In addition, the third side determines the distance between the gripping portion and the second side, so that the third side can be long enough to allow the fingers to fit in, similar to the first side. The third side may be typically 2.5 to 7 cm, preferably 2.5 to 6.5 cm, more preferably 3 to 6.5 cm, particularly preferably 3.5 to 6.5 cm, and most preferably 3.5 to 6 cm, taking into account the length sufficient to accommodate the fingers.

[0023] It is preferable that the guard member further comprises a fourth side that is formed continuously with the third side and is substantially perpendicular to the third side, which makes it possible to hold the scraper by placing the index finger or middle finger on the fourth side, improving the grip of the scraper and improving ease of handling. The fourth side may have a length sufficient to accommodate the index finger and middle finger. The length of such a fourth side may typically be 2 to 5 cm, preferably 2 to 4.5 cm, more preferably 2 to 4 cm, particularly preferably 2.5 to 4 cm, and most preferably 2.5 to 3.5 cm.

[0024] It is preferable that the first side to the third side, or the first side to the fourth side, are configured as a single member. This makes it possible to fabricate the guard member by bending the single member, which has the effect of improving the formability and economy of the guard member. The guard member may be configured to have a certain degree of thickness corresponding to the gripping member. The thickness of such a guard member may typically be 1 to 5 cm, preferably 1.5 to 5 cm, more preferably 1.5 to 4.5 cm, particularly preferably 1.5 to 4 cm, and most preferably 1.5 to 3.5 cm.

[0025] It is preferable that the guard member has rounded processing (R processing) at each connecting portion between the first and second sides, the second and third sides, and the third and fourth sides, which can improve the safety of the guard member.

[0026] In the present invention, it is preferable that all the components are made of chemical-resistant metal materials. This allows the scraper to be used without deterioration even when exposed to strong disinfectants used in specialized cleaning sites, and is also resistant to deformation even when force is applied, improving the functionality and durability of the scraper of the present invention. There is no particular need to limit the chemical-resistant metal material as long as it has chemical resistance, and various metals can be used, but typically stainless steel, titanium, titanium alloys, etc. may be used. EXAMPLES

[0027] The scraper of the present invention will be explained with reference to the drawings.

[0028] FIG. 1 is a diagram showing an example of a scraper 1. FIG. 2 is a diagram showing each part of the scraper, including a spatula part 2, a guard part 3, and a fixed part 4. 3 is a diagram showing the entire spatula member 2, which includes a spatula 21, a gripping portion 22, a screw portion 23, a front recess 24, and side recesses 25, 25'. Note that a rear recess 24' (not shown) is provided on the rear side of the front recess. FIG. 4 is a diagram showing the entire guard member, which has a first side 31, a second side 32, a third side 33, a fourth side 34, and a screw hole 35. FIG. 5 is a top view of the scraper, showing that the guard member can be fixed at various angles to the spatula member. FIG. 6 shows the scraper being held.

[0029] The scraper is composed of a spatula member 2, a guard member 3, and a fixing member 4. The guard member 3 has a screw hole 35, which is inserted into a screw section 23 provided at the end of the spatula member and fixed by the fixing member 4. As a result, the spatula member 2, guard member 3, and fixing member 4 are integrated and can be used as the scraper 1. The guard member 3 can be fixed at various angles, and can be set to a preferred angle depending on the user's operating feel and usage situation.

[0030] The scraper of the present invention will be explained using a prototype as an example. Fig. 7 shows the specifications of a prototype scraper. The prototype produced based on Fig. 7 is the scraper shown in Figs. 8 to 9.

[0031] The scraper prototype is composed of a spatula, a guard, and a fixed member (Fig. 8A). In this scraper, the angle of the guard can be freely changed with respect to the grip, and it can be fixed, for example, nearly perpendicular to the grip (Fig. 8B) or nearly parallel to the grip (Fig. 8C).

[0032] The scraper can be held in a variety of ways depending on the angle of the guard member. For example, when the guard member is fixed approximately perpendicular to the gripping portion, it is possible to grip the spatula with all fingers inserted into the guard member (Fig. 9E). In this case, the index finger can be placed on the fourth edge to stably grip the gripping portion, and the index finger can be pressed against the third edge of the guard member to efficiently transmit force to the spatula. In addition, the third edge of the guard member can be held between the index finger and middle finger (Fig. 8, F, G, I). In this case, the middle finger can be placed on the fourth edge to stably hold the gripping portion, and the force can be efficiently transmitted to the spatula by pressing the middle finger against the third edge of the guard member. Furthermore, in either case, it becomes possible to place the thumb on the concave surface (triangular depression) near the base of the spatula, making it possible to efficiently apply force to the spatula with the thumb.

[0033] When the guard member is fixed approximately parallel to the gripping part, as in the case of approximately perpendicular, the guard member may be gripped by inserting all fingers into it, or the third edge may be pinched (Fig. 8K). Furthermore, by placing the thumb on the side recess (arc-shaped depression) of the gripping part, a stable grip and efficient application of force can be achieved.
