Abstract
A powered hand tool (10) has a body (100) and an electric motor having a gear for driving the tool in an operative direction against a workpiece, including a handle (200) for gripping by a user's hand. The handle (200) has a portion (220) facing a non-operating direction opposite to the operating direction. The handle portion (220) is resiliently deformable to absorb and thereby reduce reactive vibrations acting on the palm of the user's hand during operation of the tool (10). The portion (220) is a removable cover (210) secured to the handle (220) by a latch (300). The latch (300) includes an unlatching member (320) that can be manipulated by a person, rather than a dedicated tool, to unlatch the latch (300) and thereby release the cover (210).

The specific embodiment
At first referring to Fig. 1 to 10, illustrate and realize first power hand tool 10 of the present invention, described first power hand tool 10 is electronic hand drills 10, has the body 100 of handgun shape, the elongated handgrip or the handle 200 of suspension (depend) that described body comprises usually and gun barrel meets at right angles substantially.Identical with all traditional electronic hand drills, body 100 holds a driving mechanism, and described driving mechanism is integrated electronic and and is used to transmit electric-motor drive some gear to the most preceding chuck 100.Chuck 110 is in order to maintenance and driven tool (tool implement), that is, drill bit or driver bit make its central shaft rotation around body 100.Handle 200 is being widened the termination of opening 290 places, and the wherein said opening 290 of widening is used for the rechargeable battery pack (not shown) is contained in here.
Utilization can be handled hand drill body 100 by the handle 200 of user's grasping, is promptly acting on the workpiece on the direction of operating forward to drive cutter head.
Cover 210 last end piece 215 and engage one another by at first making, make then and cover 210 and be pivotable, against part 204, will cover 210 and be connected to handle portion 204 up to it around its upper end 214 with the lip 205 (Figure 10) of part 204.The side tabs 212 of the lid 210 in the respective slots on the relative left and right sides of insertion body 100/ handle 200 has guaranteed to connect closely cooperating between the connected part.Lid 210 lower end 216 is fastened to the lower end of part 204 by blocking device 300, and wherein said blocking device 300 is the part of hand drill 10.By putting upside down above-mentioned steps, detachable lower cover 210.
Latching member 310 has: the upper end 312 of bifurcated forms from the slit with openend of following joint lid hook 217; Lower end 314; And mid portion, present the inclined-plane that upwards is 45o.314 are provided with coil compression springs 315 around the lower end, and described coil compression springs is the whole latching member 310 of fexible bias pressure linearly upwards, simultaneously its upper end 312 with cover hook 217 and engage.
Unlock piece 320 adopts the form that is roughly columniform bar 320, in the coaxial lateral aperture 206 that is slidably received within straight right half part by handle 200, and aligns with the inclined-plane 316 of latching member 310.Bar 320 has the outer end 324 that enlarges a little of the inner 322 that contacts with inclined-plane 316 and the outer end that just is positioned at hole 206 fully.The inner outside in next-door neighbour hole 206 is clamped inner 322 C clamp 324 anti-stopping bars 320 and 206 is outwards pulled out from the hole.
Under the effect of spring 315, thereby engage when cover 210 with hook 217 when latching member 310 raises, its inclined-plane 316 make trip lever 320 by surperficial 316 and interior rod end 322 between cam act on handle hole 206 interior most external be shifted relatively (Fig. 8).Manually be pressed on the preferred recessed outer rod end 324 by the user, bar 320 further inwardly can be pushed in the hole 206 about handle portion 204.
When inwardly sliding, by the reverse cam effect between interior rod end 322 and the surface 316, bar 320 is shifted latching member 310 downwards, thereby latching member upper end 312 is broken away from from lid hook 217, covers 210 (Fig. 8 A) thereby unclamp.By when lock, lid 210 can unload from handle 200, and it can reconnect to afterwards on the handle 200 and (can use different lids as required).
Be important to note that to have suitably little end and promptly can be used for being pressed on the outer rod end 324 less than any object of the end in hole 206.Example comprises ball pen, small screw driver or screw or nail etc., and they all can be easy to obtain, and particularly is easy to obtain in workshop etc.Therefore, do not need specific purpose tool to dismantle or connection cover 210, thereby this is easily for the user.
The outer end 324 of trip lever 320 is arranged in the hole 206, to avoid its unexpected decline, that is, avoids the separation that is not intended to of handle cover 210.
An advantage is can unload lower cover 210 from handle 200, thereby another lid (referring to following) replacing that can utilize new lid or utilization to have different patterns as required to cover 210.
The cap 220 of central authorities is formed by smooth inside bar (strip) 222 and narrower outside bar 224, and wherein side cover portion 230 is from described inner bar 222 horizontal expansions, the upper and lower side of described outside bar 224 extend throughs inside bar 222.Outside bar 224 is spaced apart with inner bar 222, thus between form narrower gap, elongated expansion outer cover or air bag 240 that relative left and right sides exposes wherein are set in described gap.Outside bar 224 serves as the guard shield that is used for protective bag 240 on the outside.
The outer surface one of the inside bar 222 of the outer surface of side cover portion 230 and central cap 220 is reinstated whole thin rubber coating 224 and is covered, for holding (skid-resistant grasping).Outside bar 224 integral body are made by rubber, extend as the integral body of rubber coating 250, make that outside bar 224 can be with air bag 240 strains.
The left and right sides of air bag 240 is drawn into, and interconnects at interval with rule along the length of bag 240, the special thus elasticity that keeps the cross section of bag 230 along the middle part of bag 240.
Referring now to Figure 11 to 15,, these illustrate realizes that the of the present invention second electronic hand drill 10A, the described second electronic hand drill have the structure identical with first hand drill 10 substantially, and is equal to part and represents with the same reference numerals of interpolation suffix letter " A ".Unique difference is the pattern of handle cover 210A as described below, and described handle cover 210A is the alternatives that can exchange with lid 210 on before being used in identical hand drill handle 200/200A.
Handle cover 210A has parts of plastics 220A and the 230A that three one connect equally, and middle body 220A faces down on the not operation direction simultaneously, and extends jointly with handle 200A.Middle body 220A comprises smooth bar 222A, and sidepiece 230A is in an opposite direction from described smooth bar horizontal expansion, and has the cross section that is roughly C shape together.
The outer surface of the combination of bar 222A of central authorities and sidepiece 230A is coated with rubber coating 250A, and for holding (skid-resistant grasping), described rubber coating is included in the thicker central bar 240A that bottom bar 222A goes up stratification.Because coating 250A is crooked on smooth bar 222A in protruding mode, so rubber bar 240A is thicker.
Stronger power hand tool, no matter they are electronic or pneumatic, all should keep by both hands usually, reason is, except main handle (at the rear portion), on a side, also exist assist handle to need the another hand to keep, or described body is included in the part of holding for the another grasped on its lower surface (that is belly).Such assist handle or hold the part can be provided with according to lid of the present invention.
Although described hand drill above clearly, the present invention also can be applicable to heat and other various types of power hand tools, for example cutting machine, sweep-saw/reciprocating saw, trimmer and router base portion/annex.Should be understood that according to the present invention, the second handle of power hand tool, the side handle of hand drill for example can be made into equally and absorbs vibration.
Only provided the present invention, but those skilled in the art can make various other modifications and/or change to described embodiment, and not depart from as scope of the present invention pointed in the appended claims by means of example.
