The present invention relates to a detachable supporting device, and more particularly, to a detachable supporting device for conveniently taking and putting a pen.
A ballpoint pen is often put on the reception counter of a shopping mall or an enterprise for customers. In a conventional arrangement method, a belt is tied to the end of the ballpoint pen for convenient use of being freely taken by the customers, and the ballpoint pen is restrained by the belt to prevent the ballpoint pen from falling out of the reception counter. For replacement of the ballpoint pen, it is necessary to cut or remove the belt to separate the glue or winding section from the ballpoint pen, which is inconvenient to use. Therefore, design of a supporting device that can fasten the ballpoint pen on the reception counter and the ballpoint pen can be easily taken and detached is an important issue in the related mechanical design industry.
The present invention provides a detachable supporting device for conveniently taking and putting a pen for solving the above drawbacks.
According to the claimed invention, a detachable supporting device includes a base, an external component and a supporting portion. The base has a first side and a second side opposite to each other. The base is put on a holding surface. The external component is detachably disposed on the base. A bar of the external component has a first end and a second end opposite to each other. A first magnetic member is disposed on the first end, and a second magnetic member is disposed between the first end and the second end. The supporting portion is connected to the base. The supporting portion includes a first magnetic unit and at least one second magnetic unit. The first magnetic unit is disposed on the first side and used to cooperate with the first magnetic member to provide a magnetic attraction force. The at least one second magnetic unit is disposed on the second side and used to cooperate with the second magnetic member to provide a magnetic repulsion force. The first magnetic unit and the at least one second magnetic unit are disposed between the second magnetic member and the base.
According to the claimed invention, the at least one second magnetic unit includes two magnetic pole surfaces, wherein one of the two magnetic pole surfaces corresponds to a specific magnetic pole surface of the second magnetic member, and another of the two magnetic pole surfaces corresponds to another specific magnetic pole surface of the second magnetic member.
According to the claimed invention, the base includes a top surface and a bottom surface opposite to each other. A planar normal vector of the top surface intersects or is parallel to a planar normal vector of the bottom surface. The supporting portion further includes a plurality of stretching sections arranged on and upwardly protruding from the top surface. At least one of the first magnetic unit and the at least one second magnetic unit are disposed on the plurality of stretching sections.
According to the claimed invention, the supporting portion further includes two second magnetic units, and the two second magnetic units are respectively disposed on different sides of the external component.
According to the claimed invention, the base includes a top surface and a bottom surface opposite to each other. The bottom surface abuts against the holding surface. The supporting portion is disposed on the top surface. A height of the second magnetic member relative to the bottom surface is greater than a height of the first magnetic member relative to the bottom surface.
These and other objectives of the present invention will no doubt become apparent to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

The supporting portion 14 can include a plurality of stretching sections 14a connected to the base 12. The plurality of stretching sections 14a can upwardly protrude from the base 12 and be used for arrangement of a plurality of magnetic units. The plurality of magnetic units can cooperate with a plurality of magnetic members of the external component 16 to suspend the external component 16. A number of the stretching sections 14a can depend on a number of the magnetic units as needed. For example, the detachable supporting device 10 in the first embodiment can have three magnetic units, and the supporting portion 14 can have three stretching sections 14a disposed on a first side 121 and a second side 122 of the base 12, as shown in
In the embodiment of the present invention, the external component 16 can be a pen for writing, which depends on actual applications without any limitation, and detailed descriptions for the variations of the external component 16 are omitted herein for simplicity. A bar 22 of the external component 16 can have a first end 221 and a second end 222 opposite to each other. A first magnetic member 24 can be disposed on the first end 221, and a second magnetic member 26 can be disposed between the first end 221 and the second end 222. Numbers and shapes of the first magnetic unit 18, the second magnetic unit 20, the first magnetic member 24 and the second magnetic member 26 are not limited to the embodiment shown in
A magnetic pole surface S of the second magnetic unit 20 can correspond to a magnetic pole surface S of the second magnetic member 26, and a magnetic pole surface N of the second magnetic unit 20 can correspond to a magnetic pole surface N of the second magnetic member 26. The second magnetic unit 20 can have four non-pole surfaces set between the magnetic pole surface S and the magnetic pole surface N. One of the four non-pole surfaces can face a lateral surface of the external component 16 when the external component 16 is suspended above the base 12. The magnetic pole surface N of the second magnetic unit 20 can be disposed on an inner part of the stretching section 14a to face the base 12, and the magnetic pole surface S of the second magnetic unit 20 can be disposed on an outer part of the stretching section 14a protruding from the base 12; or, the magnetic pole surface N of the second magnetic unit 20 may be disposed on an outer side of the stretching section 14a opposite to the first magnetic unit 18, and the magnetic pole surface S of the second magnetic unit 20 may disposed on an inner side of the stretching section 14a close to the first magnetic unit 18. Arrangement of the magnetic pole surface N and the magnetic pole surface S of the second magnetic unit 20 can depend on the design demand.
It should be mentioned that an interval between the second magnetic member 26 and the first end 221 can be preferably smaller than an interval between the second magnetic member 26 and the second end 222, so that assembly of the base 12 and the supporting portion 14 can have small and exquisite appearance. Generally, the interval between the second magnetic member 26 and the first end 221 can be one third of a length of the bar 22. The interval between the second magnetic member 26 and the second end 222 can be two thirds of the length of the bar 22. A ratio of the two intervals to the length of the bar 22 can depend on the design demand.
In the present invention, when the external component 16 is disposed on the supporting portion 14, the first magnetic unit 18 and the second magnetic unit 20 are disposed under the external component 16. Both the first magnetic unit 18 and the second magnetic unit 20 can be located between the base 12 and the second magnetic member 26 of the external component 16. That is, no magnetic unit is disposed on the upper portion (that is, the upper portion close to the second end 222) of the external component 16 to cooperate with the second magnetic member 26 for providing the magnetic attraction force or the magnetic repulsion force. Besides, the two second magnetic units 20 can be disposed on different sides or opposite sides of the external component 16, respectively; the magnetic pole surfaces N (or the magnetic pole surfaces S) of the two second magnetic units 20 can provide the magnetic repulsion force respectively toward two sides of the second magnetic member 26, and a tip of the external component 16 can contact the supporting portion 14 and the bar 22 of the external component 16 can be stably suspended above the supporting portion 14 via the magnetic repulsion force.

In the first embodiment and the second embodiment, the first magnetic unit 18 and the second magnetic units 20 are respectively disposed on the upper side and the lower side of the top surface 28, and structural dimensions of the plurality of stretching sections 14a may be similar in the two embodiments. In some possible embodiment (which is not shown in the figures), if the planar normal vector V1 of the top surface 28 is parallel to or substantially parallel to the planar normal vector V2 of the bottom surface 30, the structural size of the stretching section 14a on which the second magnetic unit 20 is disposed can be greater than the structural size of the stretching section 14a on which the first magnetic unit 18 is disposed (an inclined angle of the external component 16 relative to the holding surface Sp can be similar to the embodiment shown in
