Description

Technical Field

[0001] This invention relates to a detachable support device, and more particularly to a detachable support device capable of stably supporting a target object. Background Technology

[0002] Traditional ruler knives or letter openers are usually stored directly in pen holders or cases, and are pulled out when needed. Pen holders may contain multiple colored pens, which can easily look cluttered. There are pen suspension devices on the market that use magnetic attraction to hold the pen nib on a base, and then use magnetic repulsion to push the pen body upwards, allowing the rear of the pen to levitate above the base. Therefore, designing a suspension device for ruler knives or letter openers would significantly improve their aesthetics. Summary of the Invention

[0003] The present invention provides a detachable support device capable of stably supporting a target object, thereby solving the above-mentioned problems.

[0004] Based on the above concept, the present invention proposes a detachable support device, comprising a base and a magnetic force providing module. The base includes a body portion and an extension portion. The body portion has a first side and a second side opposite to each other, and the extension portion extends outward from one side of the body portion. The magnetic force providing module is engaged with the base. The magnetic force providing module includes a first magnetic component, a first magnetic assembly, and a second magnetic assembly. The first magnetic assembly is disposed on the first side and includes a second magnetic component and a third magnetic component. The two magnetic poles of the second magnetic component face an upper surface and a lower surface of the body portion, respectively. The third magnetic component is adjacent to the second magnetic component, and one magnetic pole of the third magnetic component faces the second magnetic component. The second magnetic assembly is disposed on the second side and includes a fourth magnetic component and a fifth magnetic component. The two magnetic poles of the fourth magnetic component face the upper surface and the lower surface, respectively. The fifth magnetic component is adjacent to the fourth magnetic component, and one magnetic pole of the fifth magnetic component faces the fourth magnetic component.

[0005] According to one embodiment, the detachable support device further includes a target component detachably positioned on the base. The target component includes a main body, a magnetizable unit, and a magnetic unit. The magnetizable unit is disposed at a front end of the main body and detachably contacts a positioning area of ​​the base having the first magnetic component. The magnetic unit is disposed in a middle section of the main body to act on the first magnetic combination and the second magnetic combination.

[0006] The detachable support device of this invention utilizes a base to support a target component. The magnetic supply module of the base uses a first magnetic component to attract the magnetizable unit of the target component, and further utilizes a first magnetic combination and a second magnetic combination to support the magnetic unit of the target component in a non-contact manner, allowing the main body of the target component to stand tilted on the base. The target component may be a ruler or letter opener, suspended by a single-point support; if the target component is a pen-shaped object with a tip or a similar shape, it can also rotate around its long axis, the extent of which depends on the shape of the target component and the combination of magnetic components. The magnetic components of the magnetic supply module are preferably hidden within the base and located on the same or similar horizontal planes, but may also be exposed on the base and located on the same or similar horizontal planes. The first magnetic combination (or the second magnetic combination) arranges multiple magnetic components in a specific pattern, generating a magnetic field that provides a uniform and stable magnetic repulsion force, stably supporting the target component and preventing it from falling off the base due to slight external forces.

[0048] Please see Figure 1 , Figure 1 This is a schematic diagram of the external appearance of a detachable support device 10 according to a first embodiment of the present invention. The detachable support device 10 may include a base 12 and a magnetic force providing module 14. The base 12 is mainly composed of a body portion 16 and an extension portion 18. The extension portion 18 may extend outward from one side of the body portion 16. The body portion 16 may have a first side 161 and a second side 162 defined on other sides different from the extension portion 18. The magnetic force providing module 14 is attached to the base 12 to provide the required magnetic attraction and magnetic repulsion. In possible variations, the detachable support device 10 may further include a target component 20. The front end 201 of the target component 20 is detachably positioned on the base 12 by means of the magnetic attraction of the magnetic force providing module 14. The magnetic repulsion provided by the magnetic force providing module 14 can drive the rear end of the target component 20 to levitate above the base 12.

[0049] The magnetic force providing module 14 may include a first magnetic component 22, a second magnetic component 24, a third magnetic component 26, a fourth magnetic component 28, and a fifth magnetic component 30. The first magnetic component 22 may be disposed at one end of the extension 118 relative to the main body 16. The second magnetic component 24 and the third magnetic component 26 may be combined to form a first magnetic assembly 32, disposed on the first side 161 of the main body 16. The fourth magnetic component 28 and the fifth magnetic component 30 may be combined to form a second magnetic assembly 34, disposed on the second side 162 of the main body 16. The first magnetic component 22 is used to attract the front end 201 of the target component 20. The first magnetic assembly 32 and the second magnetic assembly 34 are respectively disposed on two opposite sides of the main body 16 to drive the rear section of the target component 20 to levitate.

[0050] The target component 20 may include a body 36, a magnetizable unit 38, and a magnetic unit 40. The shape of the body 36 may depend on the type of the target component 20; for example, when the target component 20 is a letter opener, the body 36 may be designed as an elongated blade, the variations of which depend on design requirements and will not be described in detail here. The magnetizable unit 38 is located at the front end of the body 36 and detachably contacts the positioning area 12a of the base 12 with the first magnetic component 22. The magnetizable unit 38 may be made of stainless steel, ferromagnetic material, or other materials with similar properties, or may be replaced by a magnet. The magnetic unit 40 is located in the middle section of the body 36 to act on the first magnetic combination 32 and the second magnetic combination 34. Notably, this middle section is not limited to the exact center of the body 36; it may be the middle of the body 36 but near the front or rear end, or it may be located directly at the rear end of the body 36.

[0051] like Figure 1As shown, the first magnetic pole S of the first magnetic component 22 points downwards towards the extension 18, while the second magnetic pole N faces upwards. The first magnetic pole S of the second magnetic component 24 faces the upper surface 163 of the body portion 16, and the second magnetic pole N faces the lower surface 164 of the body portion 16. The third magnetic component 26 is located adjacent to the second magnetic component 24. The first magnetic pole S of the third magnetic component 26 faces the second magnetic component 24, and the second magnetic pole N faces the opposite side from the orientation of the second magnetic component 24. Correspondingly, the fifth magnetic component 30 is located adjacent to the fourth magnetic component 28. The first magnetic pole S of the fourth magnetic component 28 faces the upper surface 163 of the body portion 16, and the second magnetic pole N faces the lower surface 164 of the body portion 16. The first magnetic pole S of the fifth magnetic component 30 faces the fourth magnetic component 28, and the second magnetic pole N faces the opposite side from the orientation of the fourth magnetic component 28.

[0052] Furthermore, the first magnetic pole S of the magnetic unit 40 corresponds to the first magnetic pole S of the second magnetic component 24, and the second magnetic pole N of the magnetic unit 40 corresponds to the second magnetic pole N of the third magnetic component 26. If the target component 20 replaces the magnetizable unit 38 with another magnetic unit, the first magnetic pole S of this magnetic unit must be oriented towards the second magnetic pole N of the first magnetic component 22 to provide magnetic attraction. In this invention, the magnetic pole characteristics of the first magnetic pole S and the second magnetic pole N are not limited to the above embodiments; for example, the first magnetic pole can also be an N pole, in which case the second magnetic pole will be modified to an S pole accordingly. The setting and variation of the magnetic poles of the first magnetic pole S and the second magnetic pole N depend on actual needs, and other possible variations will not be described in detail here.

[0053] Please see Figure 2 and Figure 3 , Figure 2 and Figure 3 This is a side view of a portion of the structure of the detachable support device 10 in different variations according to the first embodiment of the present invention. When the front end 201 of the target component 20 detachably contacts the positioning area 12a of the base 12, the angle between the body 36 of the target component 20 and the base 12 is determined by the magnitude of the magnetic repulsion force applied to the magnetic unit 40 by the first magnetic force combination 32 and the second magnetic force combination 34. The actual value of the aforementioned angle is not fixed and may vary slightly depending on the design requirements of the magnetic force providing module 14. Therefore, the present invention further defines that the central axis A1 of the magnetic unit 40 may be aligned with or pointed to the central axis A2 of the third magnetic component 26, for example, the virtual extension line of the central axis A2 will pass through the midpoint of the magnetic unit 40, such as... Figure 2 As shown; or the virtual extension line of the central axis A1 will pass through the midpoint of the third magnetic component 26, as shown. Figure 3 As shown. Alternatively, it can be defined as the misalignment error between central axis A1 and central axis A2 being less than one-third to one-quarter of the length of the smallest component of the third magnetic component 26 and the magnetic unit 40 (e.g., Figure 1The length H of the third magnetic component 26 shown is... Figure 2 The distance between the point where the virtual extension line of the central axis A1 passes through the third magnetic component 26 and the midpoint of the third magnetic component 26 is between one-third and one-quarter of the length of the third magnetic component 26 and the smallest component of the magnetic unit 40, or... Figure 3 The distance between the point where the virtual extension line of the central axis A2 passes through the magnetic unit 40 and the midpoint of the magnetic unit 40 is between one-third and one-quarter of the length of the third magnetic component 26 and the smallest component of the magnetic unit 40.

[0054] In addition, when the front end 201 of the target component 20 can detachably contact the positioning area 12a of the base 12, the projection point of the bottom end of the boundary B1 of the magnetic unit 40 onto the base 12 can be located within the range of the extension of the boundary B2 of the second magnetic component 24 and the central axis B3. In other words, as Figure 2 As shown, the left side of the magnetic unit 40 is approximately located above the boundary B2 and central axis B3 of the second magnetic component 24, and the midpoint of the magnetic unit 40 is approximately located above the midpoint of the third magnetic component 26. The lengths and relative positions of the magnetic unit 40, the second magnetic component 24, and the third magnetic component 26 are not limited to the above-described embodiment and are determined according to design requirements.

[0055] Please see Figure 4 , Figure 4 This is a schematic diagram of the external appearance of the detachable support device 10A according to the second embodiment of the present invention. In the second embodiment, components with the same number as those in the first embodiment have the same structure and function, and will not be described again here. The first magnetic assembly 32A of the detachable support device 10A may further include a sixth magnetic component 42, which is disposed on the side of the third magnetic component 26 opposite to the second magnetic component 24; the second magnetic assembly 34A further includes a seventh magnetic component 44, which is disposed on the side of the fifth magnetic component 30 opposite to the fourth magnetic component 28. The first magnetic pole S and the second magnetic pole N of the sixth magnetic component 42 may face the lower surface 164 and the upper surface 163 of the body portion 16, respectively. The first magnetic pole S and the second magnetic pole N of the seventh magnetic component 44 also face the lower surface 164 and the upper surface 163 of the body portion 16, respectively.

[0056] Please see Figure 5 , Figure 5This is a schematic diagram of the external appearance of the detachable support device 10B according to the third embodiment of the present invention. In the third embodiment, components with the same number as those in the previous embodiment have the same structure and function, and will not be described again here. The magnetic force providing module 14 of the detachable support device 10B may further include a third magnetic force assembly 46, disposed between the first magnetic force assembly 32 and the second magnetic force assembly 34. The third magnetic force assembly 46 may include at least two magnetic force components 48 and 50, whose magnetic poles are arranged in the same way as the first magnetic force assembly 32 or the second magnetic force assembly 34; or, the third magnetic force assembly 46 may also include three magnetic force components (not shown in the figure), whose magnetic poles are arranged in the same way as the first magnetic force assembly 32A or the second magnetic force assembly 34A.

[0057] Please see Figure 6 , Figure 6 This is a schematic diagram of the external appearance of the detachable support device 10C according to the fourth embodiment of the present invention. In the fourth embodiment, components with the same numbering as those in the previous embodiments have the same structure and function, and will not be described again here. The magnetic force supply module 14 of the detachable support device 10C may only include the first magnetic component 22, the second magnetic component 24, and the fourth magnetic component 28; the structural design of the target component 20 is as described in the previously disclosed embodiments. If the housing of the target component 20 is made of a lightweight material and the magnetic force supply module 14 of the detachable support device 10C does not need to provide a large magnetic repulsion force, the magnetic component configuration design of the fourth embodiment can be adopted.

[0058] In summary, the detachable support device of the present invention utilizes a base to support the target component. The magnetic force providing module of the base uses a first magnetic component to attract the magnetizable unit of the target component, and further utilizes a first magnetic combination and a second magnetic combination to support the magnetic unit of the target component in a non-contact manner, allowing the main body of the target component to stand tilted on the base. The target component may be a ruler or letter opener, suspended by a single-point support; if the target component is a pen-shaped object with a tip or a similar shape, it can also rotate around its own long axis, the extent of which depends on the shape of the target component and the combination of magnetic components. The magnetic components of the magnetic force providing module are preferably hidden inside the base and located on the same or similar horizontal planes, but they may also be exposed on the base and located on the same or similar horizontal planes. The first magnetic combination (or the second magnetic combination) arranges multiple magnetic components in a specific manner, and the magnetic field range generated can provide a uniform and stable magnetic repulsive force, stably supporting the target component and preventing it from falling off the base due to slight external forces.
