Detailed description of the invention

Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.

Fig. 1 to Fig. 3-2 is to demonstrate the exploded view of this press type writing pen, constitutional diagram and sectional view, press type writing pen of the present invention includes following components, by spring-supported pen core 10, can be inserted into the penholder 20 of pen core 10, insert from penholder 20 top and combine with penholder 20, pen core 10 is played and ejects and include in the press device 30 of effect.

Above-mentioned press device 30 includes following components: be inserted into the pen core press device 31 within penholder 20, is positioned at the flat pulling force Buckle device 32 of pen core press device 31 upper end and pen clip 33.

For playing the pulling force effect of the pulling force Buckle device 32 within press device 30, need to rely on the handle hole 21a being positioned at side, upper end of above-mentioned penholder 20 and operation outer wall 21, handle hole 21a is the operating space of pulling force Buckle device 32, operation outer wall 21 is positioned at handle hole 21a both sides, and outwardly, extend certain distance.

Above-mentioned operation outer wall 21 and the interior profile of handle hole 21a are positioned on same level line, define and include operating projection 22 in so that pen core 10 can be ejected the ejection including operation in by press device 30 on the internal face of operation outer wall 21 side. Eject and include operating projection in when pen core 10 is rendered as ejection, when releasing the ejection state of pen core 10, for making pulling force Buckle device 32 maintain a degree of pressed state, the internal face of operation outer wall 21 opposite side defines and buckles releasing guide 23, eject and include operating projection 22 in and buckle and release guide 23 and lay respectively at the both sides of handle hole 21a.

For improving the elasticity of above-mentioned pulling force Buckle device 32 and strengthening internal structure, flat pulling force Buckle device 32, its wide face (wider side) defines plumbness with handle hole 21a.

Referring to Fig. 4-1��Fig. 6, for making pulling force Buckle device 32 rise after handle hole 21a, above-mentioned pulling force Buckle device 32 is included the side that operating projection 22 contact in and is formed with pen core ejection with ejecting and includes device 40 in. Under the state that pen core 10 is ejected, eject include in operating projection 22 buckle in pen core eject include in device 40. For guide 23 can be released by buckling, and realize pen core 10 and include the course of action within penholder 20 in, the another side of pulling force Buckle device 32 (eject, with forming pen core, the side that the side including device 40 in is contrary) and be formed can move within limits buckle releasing guide hump 50.

Pen core ejection is included device 40 in and is included ejecting lead-in curve 41, in the process making pen core 10 eject, eject lead-in curve 41 guide pulling force Buckle device 32 to push the top of handle hole 21a to (direction being directed away from handle hole 21a pushes away, it is seen as from Fig. 4-1 and pushes away to the left), eject lead-in curve 41 to be rearwardly inclined upwardly gradually (near the position of handle hole 21a) from front end (one end away from handle hole 21a), inclined plane is curved surface, the afterbody ejecting lead-in curve 41 forms tomography space towards opposite direction, namely afterbody the sloping downwardly in the direction away from handle hole 21a of lead-in curve 41 is ejected, include operating projection 22 thus being formed with in can be clipped in recessed space therein so that ejecting, namely form pen core and eject fixed space 42. when including pen core 10 in, come off for making the ejection buckled in pen core ejection fixed space 42 include operating projection 22 in, the rear (near handle hole 21a place) ejecting fixed space 42 at pen core has been upwardly formed releasing inclined plane 43, and this releasing inclined plane 43 is inclined upwardly gradually from rear end (one end near handle hole 21a) forward end (one end away from handle hole 21a).

The bottom surface of above-mentioned ejection lead-in curve 41 projection forms acclivitous inclined plane from the front end (one end away from handle hole 21a) (one end near handle hole 21a) to the back-end ejecting lead-in curve 41.

Ejecting fixed position 42 for enabling the protruding end that operating projection 22 is included in above-mentioned ejection in enter pen core along the inclined plane ejecting lead-in curve 41 smoothly, the more narrow inclination radian in front end that ejection lead-in curve 41 tilts is the bigger the better.

When pen core 10 is included in, operating projection 22 is included in above-mentioned ejection in and pen core ejects the surface (towards ejecting the surface including operating projection 22 in) including operation device 40 projection in and do not come in contact, and forms the spacing of H size.

Above-mentioned buckling releases guide 23 formation inclined plane in the process from outside (side away from handle hole 21a) (side near handle hole 21a) to the inside, and this inclined plane is included operating projection 22 in towards ejection and tilted. In the process that pen core 10 ejects, buckle releasing guide hump and eject and include operating projection 50 in and be positioned at the upper end of inclined plane, do not interfere with each other with pop-up action. For making above-mentioned buckling release guide hump and eject and include operating projection 50 in and the inclined plane releasing guide 23 can slide (be seen as from Fig. 6 slide into inner side) from buckling swimmingly, it is necessary to the inclined plane of tool similar tilt degree. The inner side (buckling the lower surface releasing guide 23) buckling the inclined plane releasing guide 23 is formed with the first right-angle surface 231, one right-angle side of the first right-angle surface 231 extends in handle hole 21a, and another right-angle side then extends towards the internal face of the first outer wall 21 of corresponding side. Accordingly, the outside (lower interface) buckling the inclined plane releasing guide hump 50 forms the second right-angle surface 501, second right-angle surface 501 and the first right-angle surface 231 are adaptive, one right-angle side of the second right-angle surface 501 is directed away from the internal face direction of the first outer wall 21 of corresponding side and extends, and another right-angle side is then directed away from the direction of handle hole 21a and extends.

Operation with regard to the present invention illustrates below.

The press type writing pen of the present invention, by the pressing repeatedly to press device 30 so that pen core 10 can complete the action ejected and include in.

Referring to Fig. 6��Fig. 8, when pen core 10 is ejected, press device 30 is once pressed, and press device 30 advances to pen core 10 direction, and the ejection of penholder 20 side is included operating projection 22 in and touched the pen core of pulling force Buckle device 32 side and eject the front end of ejection lead-in curve 41 including device 40 in.

If now continuing to make press device 30 advance, eject lead-in curve 41 relatively to eject and include operating projection 22 in and move downward, its rear end will be pushed to gradually to be included operating projection 22 in ejection and contacts, in the process, pulling force Buckle device 32 will be pushed to the top (protruding towards handle hole 21a, the meaning is the direction away from handle hole 21a and elastic deformation occurs) of handle hole 21a.

As above, when towards handle hole 21a protruding, if making press device 30 advance a segment distance again, pulling force Buckle device 32 will rely on the pulling force return-to-home position (namely resetting) of self towards handle hole 21a. It is positioned at pen core to eject and include the ejection of device 40 rear end in and include operating projection 22 in and be stuck in pen core and eject fixed space 42 thus maintaining the state that pen core 10 ejects.

Owing to the bottom surface of above-mentioned ejection lead-in curve 41 projection is along in the process that moves to the back-end of front end ejecting lead-in curve 41, define inclined plane, therefore when the top that operating projection 22 reaches inclined plane is included in ejection in, when namely ejecting the rear end that the protruding end including operating projection 22 in is positioned at the bottom surface ejecting lead-in curve 41 projection, pulling force Buckle device 32 is ejected includes operating projection 22 release generation elastic deformation in, if ejecting the state including the pressurized that operating projection now releases press device 30 in, it is pushed out into the pulling force Buckle device 32 on handle hole 21a top and returns elastically original position according to self. spring-supported pen core 10 is relied on to raise the pulling force pressing position 31 within press device 30, thus, ejection is included operating projection 22 in and is inserted in pen core ejection fixed space 42, and it is connected to the bottom of pen core ejection fixed space 42, make pulling force Buckle device 32 and ejection include operating projection 22 in lock, thus maintaining the ejection state of pen core 10.

Namely along with pulling force Buckle device 30 is pushed in the handle hole 21a process tilted, ejection is included operating projection 22 in and is pushed to easily and be stabilized in pen core fixed space 42.

When pen core 10 ejects, if again press device 30 is operated, now originally buckle pen core eject the internal ejection of fixed space 42 include in operating projection 22 can and pen core eject the spacing that the bottom generation of fixed space 42 is certain, and eject fixed space 42 along pen core and move up and be easily separated, until contacting with the releasing inclined plane 43 being positioned at the pen core ejection fixed space 42 afterbody formation that device 40 is included in pen core ejection in, press device 30 moves on, releasing inclined plane 43 guides pulling force Buckle device 32 to occur elastic deformation to be pushed into penholder 10 inside.

In the process, eject and include operating projection 22 and pen core in and eject and include device 40 in and protrude the surface of formation and do not occur directly to contact, produce the spacing of about H size, the buckle inclined plane releasing guide hump 50 and the inclined plane buckling releasing guide 23 that are formed in another side contact with each other and become sliding, buckle and release guide hump 50 and be subject to buckling the pressure releasing guide 23 and make pulling force Buckle device 32 occur elastic deformation to include operating projection 22 lopsidedness in ejection, again owing to operating projection 22 is included in ejection in and pen core ejects and there is spacing H between the surface including device 40 in, thus allow for the pulling force Buckle device 32 above-mentioned elastic deformation of overall generation. hereafter, buckle releasing guide 23 to continue guiding and buckle contact guidance projection 50 and slide in penholder 20, come in contact and the abutting that cooperates until buckling the second right-angle surface 501 releasing guide hump 50 with buckling the first right-angle surface 231 releasing guide 23, thus maintaining pulling force Buckle device 32 can be constantly in the state within penholder 20, the nib press device 31 within press device 30 is raised by spring-supported pen core 10, press device 30 resets, pen core 10 is included in, eject and include operating projection 22 in and reset to pen core and eject and include the lower section of device 40 in, prepare the ejection of pen core 10 next time. eject and include operating projection 22 in and can eject with pen core and include device 40 in and do not come in contact so that the convenient action completing to include in of pen core 10.
