Referring to Fig. 1 to Fig. 4, at first form shaft element 101, it is a column-shape strip body.The flexible reset components first end 103 that will have a flexible reset components 102 of the flexible coefficient that resets that is used to reset is fixed in the combination of 104 places, a junction surface of this shaft element 101, with as a flexible reset components-shaft element mechanism 10, this flexible reset components 102 stretches out and forms bending in housing member 112 inner spaces in this junction surface 104 and is circular-arc, and then be surrounded on the outside of this shaft element 101, this flexible reset components 102 finally extends to the flexible reset components the second end 106 of least significant end, and will this flexible reset components the second end 106 imposes for example glue (being illustrated among Fig. 1 with hatching) and have the function of attaching of applying interface.In the present embodiment, flexible reset components 102 is a shell fragment member, and this shell fragment member can be a sheet metal.Note that the length of this shell fragment member is less than the circumference of this shaft element 101 when flexible reset components 102 is the shell fragment member.One flexible thin shape member 107 is set, make its first flexible thin shape component ends 108 be connected in this flexible reset components the second end 106, and be wound in this shaft element with flexible reset components 102 101, this flexible thin shape member 107 finally is wound to the second flexible thin shape component ends 109 of least significant end, finish flexible thin shape member-shaft element mechanism 11, shown in Fig. 2 B.Flexible thin shape member 107 can be long paper slip, film, sheet, sheet metal, cloth etc.Then this flexible thin shape member-shaft element mechanism 11 is nested with to having shell nozzle 110 and case side among the housing member 112 of skew wall 111, notes that the end 105 of shaft element 101 need expose the perforation 113 of the upper surface that is positioned at this housing member 112.Then couple the lower ending opening 115 of a base 114, to hold this flexible thin shape member-shaft element mechanism 11 to housing member 112.Wherein, the bottom of this housing member 112 has a fulcrum 122, is used to support the bottom of this shaft element 101, and rotates this shaft element 101.When rolling out this flexible thin shape member 107, the part of the exposed surface of this flexible thin shape member 107 of being curled is contacted with the inner surface of this housing member 112 in the radius of curvature of this shaft element 101.Note when the second flexible thin shape component ends 109 passes through this shell nozzle 110, the second flexible thin shape component ends 109 of this flexible thin shape member 107 is subjected to the guiding of this case side to skew wall 111, further this case side of contact is to skew wall 111, so that flexible thin shape member 107 extended shell nozzles 110.Then, can be nested with housing member 112 to having in the shaft of a writing brush member 118 corresponding to the shaft of a writing brush opening 116 of this shell nozzle 110 and shaft of a writing brush side direction skew wall 117, and make this shaft of a writing brush member 118 be coated on the outside of this housing member 112, to skew wall 111 and corresponding shaft of a writing brush opening 116, this shaft of a writing brush side direction skew wall 117 guidings second flexible thin shape component ends 109 stretches out outside the shaft of a writing brush member 118 by shaft of a writing brush opening 116 by this shell nozzle 110 and case side.Further, the upper end 119 of this shaft of a writing brush member 118 has a rotation shaft opening 120, uses so that expose the end 105 of this shaft element 101.Then, the upper end 119 of a rotating member 121 in this shaft of a writing brush member 118 is set, and engages, to be involved in or to roll out this flexible thin shape member 107 by rotating this shaft element 101 with the end 105 of this shaft element that exposes 101.After rolling out this flexible thin shape member 107, the user also can block this flexible thin shape member 107 and use with convenient.And flexible reset components 102 can contact so that the skin of flexible thin shape member is kept with the inner surface of this housing member in order to keep the suitable space between housing member 112 and the shaft element 101.But those skilled in the art can understand, not necessarily rolling device to be installed within the shaft of a writing brush member 118 and just can use, rolling device can use separately or be installed in other the structure in and act on.
Fig. 4 is the stereogram of rolling device 13, wherein, couples an engagement member 131 in the lower end of shaft of a writing brush member 118, as being connected of rolling device 13 and the member 14 of starting writing.With reference to Fig. 5, make up the pen 15 of starting writing member 14 and forming the tool rolling device in the lower end of engagement member 131 at last.
With reference to Fig. 6, it shows an end face of rolling device, and Fig. 6 shows that the flexible reset components first end 103 of this flexible reset components 102 is surrounded on the outside of this shaft element 101 for the mode with the circular arc bending in stretching out of this junction surface 104.
The user can be divided into thrust and pulling force by application of force direction for the application of force of shaft element 101, when application of force direction when desiring to roll out flexible thin shape member 107, be called thrust P1, when application of force direction when desiring to be involved in flexible thin shape member 107, be called pulling force P2.Because pulling force P2 is effective situation, below effective (can roll out flexible thin shape member 107) application of force condition of thrust P1 only is described.
Flexible reset components 102 itself has the bending coefficient that resets, with these flexible reset components first end 103 conduction one thrusts or a pulling force certainly to this flexible reset components the second end 106.The bending coefficient that resets is these flexible reset components 102 stressed character that this flexible reset components 102 is resetted, and its material with flexible reset components 102 is relevant.The bending coefficient that resets is defined as follows shown in the formula (1):
K=F/S (1)
Wherein K is the bending of flexible reset components 102 coefficient that resets, and F is the effective application of force to this flexible reset components 102, and S is the displacement of this flexible reset components 102.Can be as seen from the above equation when K be very little, then very little application of force F can produce very big displacement, and this flexible reset components 102 still can reset and can not be out of shape.Because the distortion of this flexible reset components 102 can make this rolling device invalid, so the bending of this flexible reset components 102 coefficient that resets is subjected to this thrust bending indeformable minimum bend coefficient that resets that resets for making this flexible reset components 102.And the bending of this flexible reset components 102 resets coefficient greater than making this thrust P1 be dispersed in the minimum flexible coefficient that resets on the surface of this flexible reset components 102 in uniform mode, so that produce uniform stiction and kinetic force of friction between this flexible reset components 102 and this flexible thin shape member 107, and this bending is resetted stiction that coefficient produced and kinetic force of friction less than or this thrust that equals to allow (for example user's thrust of Yun Xuing), can effectively roll out this flexible thin shape member 107.Wherein have reset this flexible reset components of coefficient of this bending and formed by arbitrary material of selection in the group that following material constituted, this group comprises: adhesive tape, sheet, hard paper material.That is, user's thrust P1 must satisfy following formula:
P1≥f1
max (2)
F1 wherein
MaxMaximum for stiction.Because less than the maximum of stiction, therefore needing only thrust can the generation effect greater than the maximum of stiction usually for kinetic force of friction.In other words, when formula (2) is set up, then flexible thin shape member 107 outwards can be promoted, when flexible thin shape member front end 1071 goes to shell nozzle 110, this flexible thin shape member front end 1071 is subjected to this case side to pass housing member 112 to skew wall 111 guiding, and then this flexible thin shape member front end 1071 is subjected to the guiding of shaft of a writing brush side direction skew wall 117, and continuation outwards passes and passes shaft of a writing brush member 118 at shaft of a writing brush opening 116, rolls out suitable length for use.When formula (2) when being false, then can't promote flexible thin shape member 107 and outwards roll out.On the other hand, desire reduces user's thrust P1 and still keeps the effect that rolls out flexible thin shape member 107, then can change the material of flexible reset components 102, to reduce stiction and kinetic force of friction.But it should be noted, the bending of flexible reset components 102 resets coefficient can not be too little, in order to avoid the situation of depressed deformation takes place, so then can make flexible reset components 102 lost efficacy (user's rotating shaft member 101 but flexible thin shape member 107 can't be rolled out) when rolling out.The flexible coefficient that resets that flexible reset components 102 has is to make this flexible reset components be subjected to this thrust to lose the minimum flexible coefficient that resets of reset function.That is, the bending of the flexible reset components 102 load intensity H that coefficient constitutes that resets answers perseverance to satisfy formula (3):
H≥f1
max (3)
On the other hand, the difference of the frictional force of the each point on the flexible thin shape member 107 should be limited in the scope, makes this flexible thin shape member 107 be mean forced haply.If the suffered frictional force difference of each point of this flexible thin shape member 107 is too big, then can make flexible thin shape member 107 do for oneself Texturized or can't suitably be contacted with the inner surface etc. of housing member 112, rolling device was lost efficacy.That is, the bending of flexible reset components 102 reset coefficient should be greater than the minimum required bending coefficient that resets, so that produce uniform kinetic force of friction and stiction between this flexible thin shape member 107 and this flexible reset components 102.
With reference to the embodiment of rolling device shown in Figure 7, this flexible reset components 102 is by selecting the arbitrary material in the group that following material constituted to be formed, and this group comprises: adhesive tape, film, sheet, hard paper material.Above-mentioned material can make formula (2) and formula (3) perseverance for setting up.When this flexible reset components 102 when selecting the material from above-mentioned group, a groove 16 is set with ccontaining this flexible reset components 102 at this shaft element 101, and pass through a fixture 17 these grooves 16 of embedding and fix this flexible reset components 102 in this shaft element 101, strengthen the intensity of combination.Flexible reset components 102 can utilize viscose glue and be adhered in the groove 16.
When flexible reset components 102 is shell fragment (it can be a sheet metal), this flexible reset components 102 has the flexible coefficient that resets that is used to reset, in order to when rolling out this flexible thin shape member 107, the part of the exposed surface of this flexible thin shape member 107 of being curled is contacted with the inner surface of this housing member 112 in the radius of curvature of this shaft element 101.Be defined as circumference by length, also can make flexible thin shape member 107 be mean forced less than shaft element 101 with shell fragment.
Further, also can select to form the material of housing member 112, with the material formation housing member 112 of low-friction coefficient, thus minimizing user's thrust P1.Above-mentioned material must satisfy the maximum static friction force f2 between housing member 112 and the flexible thin shape member 107
MaxLess than or equal thrust P1, and thrust P1 must less than or equal the load intensity H of flexible reset components 102, in order to avoid flexible reset components 102 produces the situation of deformation failures.That is to say, must satisfy following formula:
f2
max≤P1≤H (4)
Any material that satisfies formula (4) all can be used as the material of housing member 112.For example, housing member 112 can be the plastic cement material of low-friction coefficient.
The present invention has the following advantages at least:
(1) reduces the difficulty that needs to make scroll spring.
(2) reduce the length of flexible reset components and reduce the manufacturing cost of flexible reset components, and also do not need to adopt the expensive injection method of imbedding.
(3) avoid the problem that rolls out inefficacy of flexible thin shape member effectively.
