DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0102] A few preferred embodiments of the present application are described below with reference to the drawings accompanying so that the techniques disclosed herein become more apparent and better understood. The present application may be embodied in many different forms, and its scope sought to be protected hereby is not limited only to the embodiments disclosed herein.

[0103] Throughout the accompanying drawings, structurally identical parts are indicated with the identical reference numerals, and structurally or functionally similar components are indicated with similar reference numerals. In the drawings, the size and thickness of each component are arbitrarily depicted, and the present application is not limited to the size or thickness of any component. For greater clarity of illustration, the thicknesses of some parts may be exaggerated somewhere in the drawings.

[0104] This application provides a combination tool including a first tool component and a second tool component. The first tool component includes a working portion and a grip portion, which are coupled to each other. The grip portion is provided with a tool receptacle in which the second tool component is detachably disposed. The combination tool may further include a damping mechanism for preventing accidental disengagement of the second tool component from the first tool component. The combination tool of the present application will be described below with the first tool component being implemented as a scraper as an example.

[0105] Reference is now made to FIG. 1, a schematic diagram showing the structure of a multifunctional scraper according to an embodiment of the present application. This application provides a multifunctional scraper including a scraper blade 1 and a handle 2 secured to the scraper blade 1. The scraper blade 1 is adapted to perform a scraping or shoveling function of the multifunctional scraper and serves as a primary working part of the multifunctional scraper. It is typically made from a metallic or ceramic material. For example, the metallic material may be an aluminum alloy, aluminum or steel material. The handle 2 is typically a wooden, plastic, ceramic or steel handle. The handle 2 secured to the scraper blade 1 is a portion of the multifunctional scraper to be gripped by a hand. An operator can conveniently use the tool through gripping the handle.

[0106] Differing from existing scrapers, the multifunctional scraper of the present embodiment further includes a tool receptacle 3 and a second tool 4. The tool receptacle 3 is provided in the handle 2 and adapted to the second tool 4 in terms of shape and size. The second tool 4 can be movably inserted in the tool receptacle 3.

[0107] In the present embodiment, the tool receptacle 3 is provided to accommodate the second tool 4 in a space of the handle 2. Therefore, the tool receptacle 3 is provided in a body of the handle 2. The tool receptacle 3 may be formed either integrally with the handle 2, or later in the handle 2 by machining, as long as the second tool 4 can be received therein while not affecting the operator's comfort when gripping the handle 2 with his/her hand.

[0108] For example, as shown in FIG. 1, the tool receptacle 3 is provided in a middle portion of the handle 2. Of course, according to the present application, the tool receptacle 3 may also be provided elsewhere in the handle 2, e.g., at a trailing end of the handle 2, along an axis of the handle 2, or transversely to the handle 2. It may be provided as described previously, so a further description is omitted.

[0109] As the tool receptacle 3 is intended mainly to accommodate the second tool 4, it shall be adapted to the second tool 4 to be accommodated therein in terms of shape, size, depth, opening width and other dimensions. For example, the second tool 4 may be a Phillips screwdriver bit. Of course, another tool suitable to be placed in the handle 2, such as a knife blade, a tape measure or a screwdriver bit in a different form, may also be placed therein as needed.

[0110] Therefore, by providing the tool receptacle 3 in the handle 2 of the multifunctional scraper and disposing the second tool 4 such as a screwdriver bit or a knife blade therein, the second tool 4 can be conveniently carried, and rapidly picked up or stowed, by the operator such as a painter during operation. To this end, the second tool 4 is movably inserted in the tool receptacle 3, and this movable insertion may be accomplished in a non-fastening manner involving contact and friction between surfaces of the second tool 4 and the tool receptacle 3, snap elements or the like, and requires the tool receptacle 3 to be adapted to the second tool 4 in terms of size and shape.

[0111] During the performance of a scraping or shoveling operation by the operator using the multifunctional scraper, when there is a need to use the second tool 4 such as a screwdriver bit or knife blade, he/she can take the second tool 4 out of the handle 2, and put it back into the tool receptacle 3 in the handle 2 after the use. Thus, it is both conveniently accessible for use and not easily lost.

[0112] In the multifunctional scraper of the present application, the second tool 4 is movably inserted in the tool receptacle 3. Considering the second tool 4 and/or the handle 2 is/are usually made of a metallic material, plastic or the like, in order to achieve greater friction and guarantee, to a certain extent, stable stay of the second tool 4 in the tool receptacle 3, an anti-slip measure may be taken in the present embodiment. For example, a damping mechanism may be arranged on at least one inner wall of the tool receptacle 3. For example, the damping mechanism may be provided at the bottom of the tool receptacle 3. For example, the damping mechanism may be an elastic snap element, or a magnetic element, or an anti-slip silicone coating.

[0113] For example, the elastic snap element may be disposed at the bottom or on a side wall in the tool receptacle 3. The magnetic element may be magnetic steel, which may also be referred to as a magnet. The magnetic element may be disposed at the bottom of the tool receptacle 3. The anti-slip silicone coating may be arranged on at least one inner wall of the tool receptacle 3. For example, the anti-slip silicone coating may be provided on a bottom surface, an inner circumferential surface or all the inner surfaces of the tool receptacle 3. Of course, other anti-slip materials or measures are also possible. This can additionally enhance the utility and convenience of use of the multifunctional scraper of this application.

[0114] According to another embodiment of the present application, the second tool 4 placed in the tool receptacle 3 may also be a Phillips screwdriver bit, a knife blade, or another tool.

[0115] For example, when the second tool 4 is a Phillips screwdriver bit or a knife blade, the tool receptacle 3 is provided in a middle portion of the handle, and the Phillips screwdriver bit or knife blade is movably inserted in the tool receptacle 3. The Phillips screwdriver bit or knife blade can be taken out of the tool receptacle 3 for use. In order to prevent the Phillips screwdriver bit or knife blade from easily slipping out of tool receptacle 3, a damping mechanism is provided on at least one inner wall of the tool receptacle 3. For example, the damping mechanism may be a protruding snap element, or a magnetic element, or an anti-slip silicone coating. For example, a protruding elastic snap element may be integrally formed with at least one inner wall of the tool receptacle 3, or another damping mechanism in a different form may be provided thereon, as long as it can keep the Phillips screwdriver bit or knife blade stably staying in the tool receptacle 3.

[0116] In another embodiment of this application, a linear screwdriver bit or a reversible bit, another type of commonly used hand tool, may be disposed, as the second tool, in the tool receptacle 3 in the multifunctional scraper of the present embodiment. For example, the tool receptacle 3 may transversely extend through the handle 2 and thus form a linear through hole. Due to the transverse extension, either one or more than one, e.g., two or three, of such tool receptacles 3 may be provided, depending principally upon a length of the handle 2 as well as the size of the screwdriver bit. The linear screwdriver bit can also be movably inserted in the tool receptacle 3, i.e., transversely placed in the through hole in the handle 2. Because of the structural nature of the through hole, the linear screwdriver bit received therein can be conveniently removed from either side thereof.

[0117] In another embodiment of this application, in order for even higher spatial utilization to be achieved, another tool receptacle extending longitudinally with respect to the handle 2 may be provided at the trailing end of the handle 2. For example, in the case of providing the tool receptacle 3 extending longitudinally with respect to the handle 2 at the trailing end of the handle 2, an end cap may be additionally provided at the trailing end of the handle 2. The end cap is threadedly coupled to the handle 2. When the end cap is tightened on the handle, it will delimit, together with the longitudinal tool receptacle 3, an enclosed cavity in which the linear screwdriver bit can be placed. When there is a need to use the linear screwdriver bit in the cavity, the end cap can be turned and removed to allow the linear screwdriver bit to be accessed for use. As used in this specification, the linear screwdriver bit refers to a linearly-shaped screwdriver bit with bit working portions at both ends. The two bit working portions may be identical. Of course, they may also be different.

[0118] In the multifunctional scraper of the present embodiment, apart from the Phillips screwdriver bit, knife blade or linear screwdriver bit as described and illustrated above, the second tool 4 may also be implemented as an L-shaped bit tool or a hammer.

[0119] In case of the second tool 4 being implemented as an L-shaped bit or a hammer, the tool receptacle 3 is adapted to the L-shaped tool or hammer in terms of size and shape, and the L-shaped bit is movably inserted in the tool receptacle. In the present embodiment, the L-shaped bit is a bit tool component in a shape like the letter L and with working portions at both ends, one of which is a screwdriver bit and the other is a crowbar claw. In the present embodiment, the hammer, as a type of commonly used hand tool, also has two ends, one of which may define a hammer working portion that can be used to strike an object with its own gravity, and the other may define a screwdriver bit, which is a movably fixed screwdriver bit, for example.

[0120] In the multifunctional scraper of the present embodiment, in order to allow more convenient removal of the second tool 4 inserted in the tool receptacle 3, a curved depression may be formed, for example, by cutting, around an externally exposed end of the tool receptacle 3. It is to be particular noted that, in the present embodiment, the curved depression is formed by additionally machining the handle 2 to further remove the material thereof around the externally exposed end of the tool receptacle 3. With the curved depression, part of an interface of the second tool 4, especially a portion thereof allowing convenient access by the operator, is exposed. Such a profile enables the operator to more conveniently to pull and remove the second tool 4 from the tool receptacle 3.

[0121] In another embodiment of this application, when the second tool 4 is made of a steel material, a magnetic element, such as magnetic steel, may be additionally embedded at the bottom of the tool receptacle 3 so that the second tool 4 can be kept in the tool receptacle 3 by an attractive magnetic force from the magnetic element.

[0122] In addition, tape measures are a type of measuring tools commonly used in the fields of building construction, engineering decoration, etc. The multifunctional scraper of this application can additionally incorporate the functionality of a tape measure. In case of the second tool 4 being implemented as a tape measure, the tool receptacle 3 is provided at the trailing end of the handle 2, and the tape measure may be movably inserted in the tool receptacle 3 at the trailing end of the handle 2.

[0123] The multifunctional scraper of the present application will be further described below additionally in connection with specific examples of the second tool.

[0124] Reference is now made to FIG. 2, a schematic exploded view of the structure of a multifunctional scraper according to another embodiment of the present application. In the present embodiment, the multifunctional scraper includes a scraper blade 1, a handle 2 and a Phillips screwdriver bit 21. The Phillips screwdriver bit 21 serves as a second tool, and a tool receptacle 3 is provided in a middle portion of the handle 2. The tool receptacle 3 is adapted to the Phillips screwdriver bit 21 in terms of shape and size. For example, as shown in FIG. 3, the Phillips screwdriver bit 21 can be movably inserted in the tool receptacle 3.

[0125] The Phillips screwdriver bit 21 may be, as shown in FIG. 4, a screwdriver bit with four Phillips bit working portions 211 extending in four mutually perpendicular directions. In order to provide the operator with more options and greater convenience, each Phillips bit working portion 211 may have a different function.

[0126] On an inner wall of the tool receptacle 3, a protruding snap element 5 is provided. For example, the protruding snap element 5 is integrally formed and can securely lodge the Phillips screwdriver bit 21 within the tool receptacle 3 and prevent it from slipping out of the tool receptacle 3.

[0127] In order to enable the Phillips screwdriver bit 21 to be conveniently pulled and removed from or placed back into the tool receptacle 3, a curved depression 6 is provided around an externally exposed end of the tool receptacle 3. The curved depression 6 may be formed, for example, by a cutting process.

[0128] In order to more securely keep the Phillips screwdriver bit 21 in the tool receptacle 3, an anti-slip silicone coating is provided on a side wall of the tool receptacle 3 to increase friction between surfaces of the tool receptacle 3 and the Phillips screwdriver bit 21, thus preventing easy dislodgement of the Phillips screwdriver bit 21 from the tool receptacle 3.

[0129] Thus, during use of the multifunctional scraper of the present embodiment by the operator, when there is a need to use the Phillips screwdriver bit 21, he/she can take it out of the handle 2 for use.

[0130] Reference is now made to FIG. 5, a schematic exploded view of the structure of a multifunctional scraper according to a further embodiment of the present application. The multifunctional scraper of the present embodiment includes a scraper blade 1, a handle 2 and a knife blade 22. The knife blade 22 serves as a second tool, and a tool receptacle 3 is provided in a middle portion of the handle 2. The tool receptacle 3 is adapted to the knife blade 22 in terms of shape and size. The knife blade 22 can be movably inserted in the tool receptacle 3.

[0131] On an inner wall of the tool receptacle 3, a protruding snap element 5 is provided. For example, the protruding snap element 5 is integrally formed and can securely lodge the knife blade 22 within the tool receptacle 3 and prevent the knife blade 22 from slipping out of the tool receptacle 3.

[0132] In order to enable the knife blade 22 to be conveniently pulled and removed from or placed back into the tool receptacle 3, a curved depression 6 is provided around an externally exposed end of the tool receptacle 3. For example, the curved depression 6 may be formed by cutting around the externally exposed end of the tool receptacle 3.

[0133] In order to more securely keep the knife blade 22 in the tool receptacle 3, an anti-slip silicone coating is provided on a side wall of the tool receptacle 3 to increase friction between surfaces of the tool receptacle 3 and the knife blade 22, thus preventing easy dislodgement of the knife blade 22 from the tool receptacle.

[0134] During use of the multifunctional scraper of the present embodiment by the operator, when there is a need to use the knife blade 22, he/she can take it out of the handle 2 for use. This can provide the operator with more options and greater convenience.

[0135] FIG. 6 is a schematic diagram showing the structure of a multifunctional scraper according to a further embodiment of the present application. The multifunctional scraper of the present embodiment includes a scraper blade 1 and a handle 2. The handle 2 is provided with three tool receptacles: a first tool receptacle 31 and a second tool receptacle 32, both transversely extending through the handle 2; and a third tool receptacle 33 provided at a trailing end of the handle 2 and extending longitudinally with respect to the handle 2.

The Phillips screwdriver bit 50 of this embodiment differs from that of FIG. 4 in that, as shown in FIG. 18, a central portion of the Phillips screwdriver bit 50 (which is a main body portion integrating the four working portions 501 into a single part) defines a through slot 502 extending therethrough in its direction of thickness. A separate screwdriver bit 60 can detachably engage in the through slot 502. When the separate screwdriver bit 60 is perpendicularly inserted into the through slot 502, an operator may rotate the Phillips screwdriver bit 50 to actuate the separate screwdriver bit 60. In other words, the Phillips screwdriver bit 50 can serve as an actuating handle for the separate screwdriver bit 60, and can be combined with the separate screwdriver bit 60 into a complete screwdriver. This can additionally expand the scope of application of the combination tool of this embodiment. Preferably, the through slot 502 is hexagonal, and the separate screwdriver bit 60 includes a cross-sectionally hexagonal shaft and a bit tip jointed to the shaft. The shaft matches the through slot in size and can be inserted into the through slot. The bit tip may be any common screwdriver bit known in the art. It will be understood that the present application is not limited to any particular shape of the through slot and the shaft, and any suitable shape or structure can be used herein as long as it enables the through slot and the shaft to remain stationary relative to each other in an intended direction of rotation.

[0155] The Phillips screwdriver bit 50 of this embodiment may be secured within the tool receptacle 51 in the handle 2 by virtue of any of the above discussed damping mechanisms shown in FIGS. 1 to 15. Possible embodiments of the damping mechanism may include, but are not limited to: (1) an anti-slip silicone coating applied to a side wall of the tool receptacle 51, which can create greater friction between the Phillips screwdriver bit 50 and the side wall of the receptacle 51, preventing the screwdriver bit 50 from dislodging from the receptacle 51; (2) a magnetic attraction means provided on the side wall of the tool receptacle 51, which can create a magnetic force for retaining the screwdriver bit 50; and (3) an elastic snap element 5 disposed at an opening of the receptacle 51 so as to protrude from the opening, which, when the screwdriver bit is inserted into the receptacle, comes into contact with and thereby retains screwdriver bit by means of elasticity. It will be understood that any other approach or configuration capable of retaining the Phillips screwdriver bit 50 within the receptacle may be suitably used herein, and the present application is not limited to any particular such approach or configuration.

[0156] In a further embodiment, as shown in FIGS. 19 and 26, a retention insert 61 is provided in the tool receptacle 51, which, when the Phillips screwdriver bit 50 is inserted into the tool receptacle 51, can restrict, support and retain the Phillips screwdriver bit 50. The retention insert 61 may be disposed on a side wall 512 of the tool receptacle 51 in its direction of thickness so as to extend from the side wall 512 toward another side wall 513 in opposition. The Phillips screwdriver bit 50 can be inserted into the tool receptacle 51 so as to be located between the retention insert 61 and the other side wall 513 of the tool receptacle 51. In some implementations, the retention insert 61 includes a first retention insert 611 and a second retention insert 612, which are disposed in opposition to each other. The first retention insert moiety 611 is located proximate the bottom of the tool receptacle 51, while the second retention insert 612 is located proximate the opening of the tool receptacle 51 that opposes the bottom. Preferably, an end face of the second retention insert 612 is flush with the opening. The Phillips screwdriver bit 50 may be inserted into the tool receptacle 51 so that the first retention insert 611 and the second retention insert 612 support opposite ends of the Phillips screwdriver bit 50. In some implementations, the first retention insert 611 includes raised portions 613 at its opposite ends and a recessed portion 614 between the two raised portions 613. The raised portions 613 serve to support and retain the Phillips screwdriver bit 50. The second retention insert 612 is structured similarly to the first retention insert 611.

[0157] In some embodiments, in order to allow the Phillips screwdriver bit 50 to be more easily taken out of the tool receptacle 51, referring to FIG. 18, a notch 511 is provided on one side of the opening of the tool receptacle 51, through which a user can access the Phillips screwdriver bit 50 and take it out of the tool receptacle 51. In some embodiments, in order to allow the Phillips screwdriver bit 50 to be more easily taken out, a pull-out feature 70 may be provided on the Phillips screwdriver bit 50. For example, as shown, the pull-out feature 70 may include a pull-out means provided on the Phillips screwdriver bit 50, and a user can take the Phillips screwdriver bit 50 out by exerting a force on the pull-out means. In addition, in order to facilitate stowing of the pull-out means and prevent it from being exposed outside the handle 2, an avoidance feature 71 may be provided on the side of the opening opposite to the notch 511. Preferably, the avoidance feature 71 takes the form of a depression formed in the side wall 513. When the Phillips screwdriver bit 50 is inserted in the tool receptacle 51, the pull-out means can be stowed in the avoidance feature 71. The pull-out means may be in the form of a rope, loop, ring or the like. In the illustrated embodiment, the pull-out means is a loop formed by a thread passed through a slot 72 in the Phillips screwdriver bit 50.

[0158] In order to facilitate stowing of the separate screwdriver bit 60 for use with the Phillips screwdriver bit 50, referring to FIG. 22, the handle 2 may define a tool receptacle 601, in which the screwdriver bit can be received. With this arrangement, both the Phillips screwdriver bit 50 and the corresponding separate screwdriver bit 60 can be stowed conveniently. The Phillips screwdriver bit 50 can be used either separately or in combination with the separate screwdriver bit 60, expanding the scope of application. It will be understood that the screwdriver bit 60 may also be used with a different screwdriver bit. The tool receptacle may be of the same structure as is shown in FIG. 7. That is, a receptacle 31 and/or 32 for receiving the screwdriver bit may be formed in a side surface of the handle 2, and the screwdriver bit may be stored in the receptacle 31 and/or 32. In FIG. 7, the tool receptacle defines a lengthwise direction perpendicular to the side surface of the handle 2, and the screwdriver bit is stored in the handle 2 in an orientation perpendicular to the handle 2. In another embodiment, the tool receptacle 601 may extend parallel to the side surface of the handle 2, i.e., in parallel to a lengthwise direction of the handle 2, and the screwdriver bit can be received in the receptacle. In order to firmly retain the screwdriver bit 60 in the tool receptacle 601, one or more damping mechanisms may be provided in the tool receptacle 601. These damping mechanisms may function in the same or similar way as those for retaining the Phillips screwdriver bit 50 as described above and, therefore, need not be described in further detail herein.

[0159] In some embodiments, referring to FIGS. 19 and 23, a can opener 73 for opening a cover of a container in the form of a can, such as a paint can, is provided on the handle 2 at its end proximate the scraper blade. Preferably, the handle 2 defines a protrusion 74 extending from its end in opposition to the scraper blade 1. The scraper 1 serves as a lever member of the can opener 83, and the protrusion 74 is intended to be brought into contact with a cover of a container in the form of a can, providing a point of force application. With this arrangement, the cover of the container can be easily removed. In other words, the protrusion and the scraper blade make up an extractor.

[0160] In this embodiment, the handle provides a larger storage space, in which various other tools having a different function from that of the first working portion can be stored. Integrating a variety of tools in a single unit in this way allows convenient carrying, expands the scope of application and enables easy operation. Meanwhile, the other tools can be well retained by respective features of the handle. This allows both convenient carrying and easy removal of the tools.

[0161] A Multifunctional scraper provided in the present application has been detailed and introduced above. Specific examples are presented herein to explain the principles and embodiments of the multifunctional scraper provided in this application, and the description of the foregoing embodiments is intended only to help understand the method of this application and its core concept. It is noted that a number of improvements and modifications can be made to the application by those of ordinary skill in the art without departing from the principles thereof. Accordingly, it is intended that these improvements and modifications are also embraced in the protection scope of the claims of this application.
