专利说明:

[0001] The present invention relates to a wheel element, and more particularly to a damping wheel element which is capable of serving as a transmission gear wheel in an ink ribbon cassette of a matrix printer and to provide a wheel element. press-fit function with an adjacent gear wheel in the ink ribbon cassette. The damping wheel element is also capable of serving as a wheel mounted under a light carrying means, such as a stroller, and to give the carrier a damping function. A conventional dot matrix printer is loaded with at least one ink ribbon cassette having a transmission mechanism. The transmission mechanism drives therein an ink ribbon to an inking position, so that a print head can press the ink ribbon to strike a paper to be printed.
[0002] Referring to Figure 8, it can be seen that a conventional ink ribbon cassette includes a housing 90, a driving gear 94 and a driven gear assembly. The housing 90 comprises a cavity 900. The driving gear 94 is rotatably mounted in the cavity 900 of the housing 90. The driven gear assembly is mounted in the cavity 900, is engaged with the drive gear 94 and has a mounting bracket 91, a pressure spring 92 and a driven gear 93. The mounting bracket 91 is pivotally mounted in the cavity 900. The pressure spring 92 is securely mounted between the mounting bracket 91 and a surface The driven gear 93 is rotatably mounted in the mounting bracket 91 and is engaged with the drive gear 94. The pressure spring 92 forces the slightly pivotable mounting bracket 91 to press the driven gear 93 to engage strongly with driving gear 94. Thus, inadvertent disengagement between driving gear 94 and driven gear 93 can be avoided. However, the aforementioned combination of driving gear 94, mounting bracket 91 and driven gear 93 is complicated and disadvantages the rate of production and production of the ink ribbon cassette. As a result, the cost of the ink ribbon cassette increases. In addition, a light carrying means such as a stroller comprises a stroller body and four wheels mounted on the stroller body. However, the wheels are made without damping mechanism. Thus, when the light carrier light rolls on a bumpy ground, a vibration is caused by the bumps, affects the light carrier means and interferes with an infant inside the light carrier and a user pushing the light carrier. Another carrier means having a vibration reduction device has been developed. However, the vibration reduction device thereon has a complicated structure and increases the total weight of the carrier means, which increases the cost of the carrier and disadvantage the mobility of the carrier means. To overcome these drawbacks, the present invention aims to provide a damping wheel element 30 to mitigate or avoid the problems mentioned above. The main object of the present invention is to provide a damping wheel element which is capable of serving as a transmission gear in an ink ribbon cassette of a matrix printer and to provide a press-fit function with a adjacent toothed wheel in the ink ribbon cassette. The damping wheel element is also capable of serving as a wheel mounted under a light carrying means, such as a stroller, and to give the carrier a damping function. The present invention relates to a damping wheel element characterized in that it is made of plastics material and comprises: an annular body having a through hole defined axially through the annular body; an axis axially mounted and located at the center of the through hole of the annular body; and multiple curved and elastic damping radii, deformable to decenter the axis by applying an external force on the damping spokes, and able to return to their initial position to center the axis when the external force is withdrawn, each damping radius having two ends, one end of the damping radius being connected to an inner annular surface of the annular body and the other end being connected to the axis, each damping radius comprising: a first deformable section curved and connected to the axis; a second curved deformable section formed on and extending from the first deformable section; and a third curved deformable section formed on and extending from the second deformable section and connected to the inner annular surface of the annular body. The damping spokes are simple in structure and light and can be deformed when they encounter an external force or impact, and thus provide an excellent press-fit effect and excellent cushioning effect when installed. in the ink ribbon cassette and the light weight carrier. In a particular embodiment, the annular body comprises multiple engaging members formed on an outer annular surface of the annular body. The gripping elements may be teeth. In another particular embodiment, an annular groove is defined in an outer surface of the annular body. An annular elastic member may be mounted in the annular groove. Other objects, advantages and novel features of the present invention will be further apparent from the following detailed description taken in conjunction with the accompanying drawings. In these drawings: FIG. 1 is a perspective view of a first embodiment of a damping wheel element according to the present invention; Figure 2 is a side view of the damping wheel member of Figure 1; Figure 3 is an operative view of the damping wheel element of Figure 2, showing an axis which is forced to be eccentric and spokes which are deformed; Figure 4 is a side view of the damping wheel element of Figure 2, mounted midway in an ink ribbon cassette of a printer; Figure 5 is a side view of the damping wheel element of Figure 4, fully mounted in the ink ribbon cassette and pressed against a gear wheel; - Figure 6 is a side view of a second embodiment of a damping wheel element of Figure 1, mounted on a carrying means such as a stroller; Figure 7 is a side view of a third embodiment of a damping wheel element according to the present invention; and - Figure 8 is a side view of conventional toothed wheels according to the prior art, mounted in an ink ribbon cassette. Referring to FIGS. 1 and 2, it can be seen that a first embodiment of a damping wheel element 1 according to the present invention is made of plastic material and comprises an annular body 10, an axle The annular body 10 is made of plastic material and has a through-hole 100 and multiple gripping members 11. The through-hole 100 is axially defined through the annular body 10. engagement members 11 may be teeth and are formed on an outer annular surface of the annular body 10. The axis 30 is made of plastic material and is axially mounted and located centrally of the through hole 100 of the annular body 10. If the 3, it can be seen that the damping radii 50 can be three in number, are curved and resilient, are deformed in order to decenter the axis 30 by an external force applied directly or indirectly. nt on the damping spokes 50, and return to their initial position to center the axis 30 when the external force is withdrawn. Each damping radius 50 is made of plastic and has two ends, a first deformable section 51, a second deformable section 52 and a third deformable section 53. One end of the damping radius 50 is connected to an inner annular surface. of the annular body 10 and the other end is connected to the axis 30. The first deformable section 51 is curved and connected to the axis 30. The second deformable section 52 is curved, is formed on and extends from of the first deformable section 51. The third deformable section 53 is curved, is formed on and extends from the second deformable section 52 and is connected to the inner annular surface of the annular body 10. Referring to FIG. in addition to FIG. 4, it can be seen that the damping wheel element 1 serves as a driven gear 30 and is mounted half-way in a cavity 700 of an ink ribbon cassette 70, and the axis 30 is centered in the through hole 100 of the annular body 10, in the absence of external force.
[0003] Referring further to Figure 5, it can be seen that when the damping wheel element 1 is fully mounted in the ink ribbon cassette 70, the shaft 30 is mounted in a mounting hole of the ink ribbon cassette 70 and the annular body 11 is firmly supported against a driving gear wheel 80 mounted in the cavity 700 of the ink ribbon cassette 70. A distance between an axis of the driving gear wheel 80 and the axis 30 of the damping wheel element 1 is less than the total length of the two spokes of the drive gear 80 and the damping wheel element 1. Therefore, to install the damping wheel element 1 in the cassette In ink ribbon 70, a user must force and move the axis 30 of the damping wheel element 1 to be eccentric with respect to the through hole 100 of the annular body 10. The damping radii 50 are deformed into because of the force applied by the user and the damping wheel element 1 is therefore firmly pressed against the driving gear 80 without being able to be unintentionally disengaged from the drive gear 80. Referring further to FIG. second embodiment of the damping wheel element according to the present invention is made of plastic material and serves as a wheel mounted on a carrier such as a stroller. A shock due to a bumpy ground is absorbed by the damping spokes 50 when the carrier means rolls on the bumpy ground, before reaching the axis 30 of the damping wheel element la, so that the body stroller is not affected by the shock. Thus, the damping wheel element gives it a great comfort to a user pushing the stroller and to an infant inside thereof. The annular body 10a of the damping wheel element 1a has an annular groove defined in an outer surface of the annular body 10a for receiving an annular elastic member 60 such as a tire. A maximum load of the wheel element is about 7.5 kilograms, so that a stroller having four wheel elements has a maximum load of about 30 kilograms. Referring further to Figure 7, it can be seen that a third embodiment of the damping wheel element lb has four damping spokes 50 formed in the through hole 100 of the annular body 10b. The damping spokes 50 are simple in structure and light and can be deformed when they encounter an external force or impact, and therefore provide an excellent pressurizing effect and an excellent cushioning effect when they are installed in the ink ribbon cassette and the light carrier. It is understood that the above embodiments of the present invention have been given for information and not limitation and that modifications may be made without departing from the scope of the present invention.
