Business card type instrument cases with spine move function

Technical field

The present invention relates to a kind of business card type instrument cases, finger can carry out the switching operation at the place, corner especially, and the little instrument cases that have the effect of laborsaving switching again of volume.

Background technology

Please with reference to U.S. Patent number the 6th; 243; " Tool handle combination " patent case of No. 902, it is a kind of tool handle combination, this tool handle combination is at lever body (handle body) front end installing drive rod (driving stem); The lever body has a pedestal (base), above pedestal, is covered with a lid (cover).Space in pedestal and the lid can be used for holding screwdriver head (bit) or sleeve (socket) even other instrument (tool).

Aspect carrying; Such tool handle combination has the disappearance that is not easy to carry; Because drive rod is provided in a side of on the lever body and is inseparable; Therefore cause the length of entire tool lever combination to shorten, and the article that held between the pedestal of lever body and the lid also cause the width of lever body to equate with highly being close to, make the lever body be flat column substantially and can't effectively reduce width or distance highly.Therefore, the combination of such tool handle can't become and carries the type product.

In use, the power that user's hand is executed at the lever body can reduce three kinds of strength, and first kind is the power of extending along the drive rod axis, mainly is to let screwdriver head be connected in the strength of working substances such as screw.Second kind is to make the spinning force of pivot as the power that clockwise rotates with the axis of drive rod.The third is similar to second kind, as the power that rotates counterclockwise.Because the width of lever body equates with highly being close to, so it is just quite little to offer user's application of force radius, so be a kind of design of effort.

Moreover, because lid is the part of can the person of being used opening repeatedly, so when the application of force; Lid can't effectively transmit user's the application of force; And when the user desired to impose big torsion, lid was easy to produce with respect to pedestal the problem of slip or modification, that is to say the kinetic energy consume that strength transmission can take place between pedestal and the lid; So; Can let the user feel more difficulty on using, form operational inconvenience, the problem that the lever body damaged when operation also may take place because of user's application of force is excessive what is more.

The someone made like U.S. Patent number the 6th afterwards; 405; " Tool box with bits received therein " patent case of No. 865; It is a kind of instrument cases that accommodate screwdriver head, and these instrument cases mainly include a body (body) and one can be enclosed within this external housing (cap), and body has an engagement groove (engaging recess); Engagement groove can optionally peg graft long extension bar (long bit) or screwdriver head (bit), body both sides then are provided with multi-channel (passages) and supply to take in untapped screwdriver head or long extension bar.

Aspect carrying; Because long extension bar can take off from engagement groove, so the instrument cases entire length will not comprise the length of long extension bar, and the channel of body is the both sides of running through body with the mode perpendicular to engagement groove; Then at this external housing that covers again; Make the whole width of instrument cases extend, let the whole height of instrument cases reduce, so let the instrument cases trend at pouch-type or business card type instrument cases toward body two side directions.

But with regard to the use aspect, housing is the part of can the person of being used opening repeatedly; So when the application of force, housing can't effectively transmit user's the application of force, and when the user desires to impose big torsion; Housing is easy to produce with respect to body the problem of slip or modification; That is to say the kinetic energy consume that strength transmission can take place between body and the housing, so, use to let the user feel more difficulty; Form operational inconvenience, the problem that body damaged when operation also may take place because of user's application of force is excessive what is more.

Moreover, because engagement groove is located at the body center,, form the big shortcoming on using so make this kind instrument cases to use at small space places such as corners.

The someone makes like U.S. Patent number the 7th afterwards; 032; " Toolbox screwdriver " patent case of No. 483; It is a kind of subtype instrument cases, and these instrument cases include a pedestal (base), one and are articulated in first carriage (first bracket) of pedestal one side and second carriage (second bracket) that is articulated in the pedestal opposite side.Can take in most screwdriver heads (screwdriver head) on first carriage, second carriage then is provided with a jack (receptacle hole) and supplies the bottle opener extension bar (screwdriver rod) of pegging graft.

Aspect carrying; Because the bottle opener extension bar can be accommodated in second carriage; So the instrument cases entire length will not comprise the length of bottle opener extension bar; And the whole width of instrument cases extends toward pedestal two side directions, lets the whole height of instrument cases reduce, and so lets the instrument cases trend at pouch-type or business card type instrument cases.

But, with regard to the use aspect, no matter be first carriage or second carriage; The both is the part of can the person of being used opening repeatedly, so when the application of force, first carriage or second carriage can't effectively transmit user's the application of force; And when the user desired to impose big torsion, first carriage or second carriage were easy to produce to slide or the problem of modification with respect to pedestal, that is to say that the kinetic energy that strength transmission can take place between pedestal and two carriages consumes; So; Can let the user feel more difficulty on using, form operational inconvenience, the problem that pedestal damaged when operation also may take place because of user's application of force is excessive what is more.

Moreover; Though the jack of first carriage is located at a contiguous side at pedestal; Make when instrument cases are rotated operation, can use at small space places such as corners, but be to use very not convenient; Because must make screwdriver head separate, contact the effect that to reach rotation screw smoothly with screw repeatedly, so form the big shortcoming on using.

In addition, with the plane pedestal perpendicular to the axis of jack, it is all inequality that the periphery of jack and pedestal all has the distance on four limits of different distances, particularly jack and pedestal, so instrument cases only can restrictedly use at the particular space place.

Referring to figs. 1 through Fig. 5, for the present invention has first embodiment of the business card type instrument cases 10 of spine move function, instrument cases 10 of the present invention include a body 20, a ratchet drive mechanism 30 and a rack 40;

Wherein:

The rectangular haply body of body 20 and at one end form a leading section 21, body 20 forms a forced section 22 in contrast to an end of leading section 21, and leading section 21 and forced section 22 are along a first direction X and each interval is separated.The both sides of body 20 form a first side 23 and a second side 24 respectively, and first side 23 and second side 24 are between leading section 21 and forced section 22, and first side 23 and second side 24 are along a second direction Y and each interval is separated.Body 20 also includes integrally formed two wall portions 25 that are connected between leading section 21 and the forced section 22, and said two wall portions 25 are along a third direction Z and each interval is separated.Described first direction X is perpendicular to one another with second direction Y, and described third direction Z is perpendicular to first direction X and second direction Y.That is to say that described first direction X, second direction Y are perpendicular to one another with third direction Z three and constitute three-dimensional.

The leading section 21 of body 20 is provided with an accommodation space 211.The forced section 22 of body 20 can bear user's the palm centre of the palm and the application of force of tiger, lets can securing members such as screw 90 (like Fig. 7) effectively be pressed in the operation process wait to lock on the thing.Forced section 22 offers a step shape slot 221 that extends along body 20 first direction X, and slot 221 is to supply plant bottle opener extension bar 80, and slot 221 interlinks with accommodation space 211.

Slot 221 has a phase I 222 and a second stage 223; Phase I 222 is to link to each other with forced section 22 and be open shape; Second stage 223 is to link to each other with accommodation space 211; And the internal diameter of second stage 223 is less than the internal diameter of phase I 222, and the large-diameter portion that makes the phase I 222 can hold bottle opener extension bar 80 divides 81, and second stage 223 can be held the path part 82 of bottle opener extension bar 80.Be provided with a plurality of protuberances 224 of ring-type array in the second stage 223 of slot 221, be used for the path part 82 of clamping bottle opener extension bar 80.Protuberance 224 in the present embodiment is provided with six, is used for bar-shaped minor diameter part part 82 of hexagon of clamping bottle opener extension bar 80.Because slot 221 interlinks with accommodation space 211, so slot 221 can allow that the path of bottle opener extension bar 80 partly stretches in the accommodation space 211 82 parts.

The first side 23 of body 20 is the circular arc outer surface; First side 23 forms a chamfering 231 with forced section 22 junctions; Make that so the edge of forced section 22 is the slick and sly first sides 23 that are connected in, let contact that user's tiger place can be more comfortable at chamfering 231 places.

The wall portion 25 of body 20 is integrally formed being connected between leading section 21 and the forced section 22; So can effectively improve the structural strength of body 20; And form a material-putting space 251 between said two wall portions 25, material-putting space 251 in the second side 24 or forced section 22 offer an opening.In the present embodiment, material-putting space 251 is to have an opening 252 from 24 openings of the second side of body 20.Wall portion 25 provides the function of user's finger large tracts of land contact, lets the spinning force that the user executed can effectively pass to securing member 90 through instrument cases 10 fully.And said two wall portions 25 are mutually symmetrical so go for being dextromanuality or left-handed user, can directively not limit, thereby have improved the adaptive capacity of product.

Ratchet drive mechanism 30 includes rotatable hollow form ratchet 32 and who is located in the main body 31 of a main body 31, and be used for controlling the reversing arrangement 33 that ratchet 32 clockwise rotates, rotates counterclockwise or do not rotate in main body 31.The main body 31 of ratchet drive mechanism 30 is to be incorporated in the accommodation space 211 of body 20, makes main body 31 be fixed on accommodation space 211 and can not rotate with respect to body 20.

The ratchet 32 of ratchet drive mechanism 30 is to be hubbed in the main body 31, and ratchet 32 has a rotating shaft O, and ratchet 32 is to be that rotate in the axle center with rotating shaft O, and the rotating shaft O of ratchet 32 is parallel with the first direction X of body 20.Ratchet 32 at one end is provided with a driver slot 321 that extends along rotating shaft O, and the cross section of driver slot 321 is a non-circular shape, is used for driving bottle opener extension bar 80 and rotates.Ratchet 32 driver slots 321 in the present embodiment are that to be made as hexagon poroid, have the bar-shaped bottle opener extension bar 80 of hexagon with linking.In the present embodiment, the slot 221 of body 20 is to extend along ratchet 32 rotating shaft O.

Ratchet 32 is provided with a circular storage tank 322 that extends along rotating shaft O in contrast to an end of driver slot 321; The aperture of storage tank 322 is greater than the aperture of driver slot 321; So storage tank 322 can allow that path part 82 parts that are plugged on the bottle opener extension bar 80 in the slot 221 stretch into; First distance B 1 with effective minimizing body 20 reaches the effect that body 20 is easy to carry about with one.Form a retaining portion 323 between the driver slot 321 of ratchet 32 and the storage tank 322, the path part 82 of bottle opener extension bar 80 can be blocked by retaining portion 323, prevents that bottle opener extension bar 80 from passing ratchet 32.The retaining portion 323 of ratchet 32 offers a through hole 324, is installed with a magnet 34 in the through hole 324.Magnet 34 can adsorb the path part 82 that is plugged on the bottle opener extension bar 80 in driver slot 321 or the storage tank 322, increases the binding ability between ratchet 32 and the bottle opener extension bar 80.

The reversing arrangement 33 of ratchet drive mechanism 30 have can Elastic Meshing in several engagement component (not shown) of ratchet 32; Two engagement components normally; Ratchet drive mechanism 30 utilizes the meshing relation between a change-over switch two engagement components of 331 controls and the ratchet 32 then, and then reaches the effect that selectivity makes ratchet 32 in main body 31, clockwise rotate, rotate counterclockwise or not rotate.Body 20 offers an exposed portion 212 with respect to the position of change-over switch 331, change-over switch 331 is exposed outside body 20 and can supply the user to operate, and the ratchet drive mechanism 30 of present embodiment is to adopt revolving change-over switch 331.

Rack 40 is to be installed in material-putting space 251 via the opening 252 of body 20, takes out racks 40 so that the user to be provided by the second side 24 of body 20, and the material-putting space 251 that rack 40 can enclosed body 20.Rack 40 has a placement section 41 and the outside portion 42 in contrast to material-putting space 251 towards body 20 material-putting spaces 251 inside, and outside portion 42 is used for sealing the opening 252 of material-putting space 251.The placement section 41 of rack 40 is concaved with a plurality of clamp grooves 43, for placing a plurality of screwdriver heads 83.Said a plurality of clamp grooves 43 is the vertical arrangements that become single row along body 20 first direction X-shapeds; So make the material-putting space 251 of body 20 only need possess the space that holds single row's screwdriver head 83; And then let the 3rd distance B 3 of body 20 third direction Z effectively reduce, reach the effect that instrument cases 10 are easy to carry about with one.

Rack 40 is respectively equipped with a buckling parts 45 at two ends; And body 20 is respectively equipped with a catching groove 225 near the leading section 21 and the forced section 22 of second side 24; The buckling parts 45 of rack 40 can be buckled in the catching groove 225 of body 20, rack 40 is folded behind the material-putting space 251 of body 20, be unlikely to break away from arbitrarily body 20.

Body 20 is along first direction X one first distance B 1 of ultimate range definition between leading section 21 and forced section 22; Body 20 is along second direction Y second distance D2 of ultimate range definition between first side 23 and second side 24; Body 20 is along third direction Z one the 3rd distance B 3 of ultimate range definition between two wall portions 25; The 3rd distance B 3 of body 20 is less than second distance D2; The second distance D2 of body 20 so makes body 20 present the profile of cuboid less than first distance B 1.

The second direction Y of body 20 is that the axle center defines one first radius R 1 and one second radius R 2 with rotating shaft O; First radius R 1 is body 20 first sides 23 and the distance of rotating shaft O at second direction Y, and second radius R 2 is body 20 second sides 24 and the distance of rotating shaft O at second direction Y.First radius R 1 adds that second radius R 2 equals second distance D2, and second radius R 2 is greater than first radius R 1, and first radius R 1 is less than the 3rd distance B 3 again.

Because second radius R 2 greater than first radius R 1, so effectively increased the arm of force when instrument cases 10 rotate, can reach best laborsaving switching effect.And because first radius R 1 less than the 3rd distance B 3, so instrument cases 10 just can use in narrow spaces such as corner when rotated.The best, first radius R 1 is half the less than the 3rd distance B 3, and so instrument cases 10 just can carry out wide-angle switching operation in narrow spaces such as corner.

So also we can say; Ratchet 32 is to be positioned at body 20 near leading section 21 and near 1/4th corners of first side 23,1/4th corners of body 20 refer in body 20 first distance B 1 near this of leading section 21 half the with second distance D2 near these half 1/4th zones that overlapped of first side 23.Such design can let instrument cases 10 reach minimum volume and produce maximum laborsaving switching effect, but also can carry out the switching operation at the place, corner.

The rotating shaft O of ratchet 32 is positioned on the mid-plane P perpendicular to body 20 third direction Z; Described mid-plane P is cutting away half the 3rd distance B 3 symmetries; That is to say; The rotating shaft O of ratchet 32 is positioned on the centre position of the 3rd distance B 3, makes strength when said two wall portions 25 can on average share instrument cases 10 rotation.So, because of described two wall portions 25 be mutually symmetrical remain on rotating shaft O both sides, so when instrument cases 10 rotations, any one wall portion 25 can not produce the problem that stress is concentrated.
