Description
2337228 1 Hand tool machine withh sole plate Ile invention proceeds from a
hand tool machine according to the preamble of claim 1.
From EP 0 603 552 such a hand tool machine is already known, which comprises a clamping device for clamped connection of the sole plate which by rotating a spiral-toothed gear wheel by hand - without a separate tool - is clampable and releasable from the back end of the hand tool machine, wherein the rotation of the spiral-toothed gear wheel is geared down by means of a gearing connection. Said clamping device is convenient and operationally reliable but relatively expensive to manufacture.
In contrast the hand tool machine according to the invention having the characterizing features of claim 1 has the advantage that the clamping device for releasing and fastening the sole plate relative to the hand tool machine housing comprises only a few simple, lightweight parts, is inexpensive to manufacture, ru Red and moreover operable conveniently and quickly without the aid of a tool.
99 Because of the simpler design, the hand tool machine is light to handle and therefore fatigue-proof.
The simplification of the design of the clamping device arises from the fact that a clamping lever having an eccentric head is swingable out of the plane of the sole plate and in so doing, by means of the eccentric head alone, serves as a tool-less clamping means for releasing and locking the sole plate in desired positions relative to the housing.
By virtue of the fact that the clamping lever for locking the sole plate is positionable parallel to the sole plate in the contour of the sole plate underneath the latter's underside and is swingable so as to project in the release position down from the sole plate, the clamping lever may be designed with a generous lever arm 2 length and so as to be at all times easy to locate and extremely convenient to handle.
The clamping lever by virtue of being pivotally coupled by a swivelling axis to a clamping bolt, wherein the clamping bolt is fattenable to the housing and wherein it passes through an opening of the sole plate, is' captively movable into a position which allows unimpeded handling of the hand tool machine.
By virtue of the fact that the opening of the clamping bolt takes the form of an oblong hole extending at right angles to the forward feed direction of the hand tool machine, the angle of the sole plate relative to the housing is adjustable.
By virtue of the fact that the clamping lever in the region of its swivelling axis carries an eccentric head, which is eccentrically contoured around the swivelling axis and the eccentric clamping surface of which extends at right angles to the swivelling axis and to the longitudinal axis of the clamping lever and the eccentric release surface of which extends at right angles to the swivelling axis as well as in the longitudinal axis of the clamping lever, it is possible to switch from the clamping position into the release position within an angular range of the clamping lever of approximately 90 ".
The eccentric head by virtue of being supported, in particular via a supporting plate, relative to an underside of the sole plate, preferably the abutment surface, has an advantageous proximity to its site of action.
By virtue of the fact that the clamping lever, in its clamping position extending parallel to the sole plate, has its handle projecting out beyond the back end of the sole plate, the clamping lever may be swivelled into its operating position from the back without the hand tool having to be lifted for said purpose and without the operating hand having to approach the sole plate from below.
3 By virtue of the clamping lever being supported, in particular in a ffictionally engaged, preferably positive manner, 'm its clamping position within the contour of the base plate against retaining ribs, an accidental folding of the clamping lever into its operating position or into the release position is prevented.
By virtue of the fact that the abutment surface of the sole plate carries, like a row of teeth, uniformly spaced radial projections, _associated with which is at least one corresponding recess, preferably more than one recess arranged like a row of teeth, of counterpart projections in the contour of the supporting surface of the housing, which through engagement one into the other serve to fix the housing positively 'm adjustable angular positions relative to the sole plate, preferred angular positions are adjustable extremely easily.
By virtue of the fact that the eccentric head embraces the clamping bolt in a fork-like manner and is swingable jointly with the swivelling axis relative to said clamping bolt, a particularly simple, easy-to-manufacture design of the clamping device or clamping lever is provided, whereby the clamping lever despite its wall thicknesses in the fork region is subject to only low wear because no relative movement and hence no firiction occurs between the swivelling axis and the clamping lever.
There follows a detailed description of an embodiment of the invention with reference to the accompanying drawings.
The drawings show:
Figure 1 a longitudinal section through a jig saw according to the invention; Figure 2 an enlarged cutout from the longitudinal section according to Figure 1 with a, compared to Figure 1, modified clamping lever shown in two positions; Figure 3 a cross section of the jig saw according to Figure 1 in the region of the clamping lever situated in release position; Figure 4 the cross section of the jig saw according to Figure 3 in the clamping position of the clamping lever; Figure 5 the inverted plan view of the sole plate according to Figure 1 in the release position of the clamping lever; Figure 6 the inverted plan view of the sole plate according to Figure 1 in the clamping position of the clamping lever; Figure 7 a partial longitudinal section of the clamping lever with clamping bolt as an individual part according to Figure 1; and Figure 8 a partial longitudinal section according to Figure 7 but rotated 90 0 about the longitudinal axis and swivelled at right angles relative to the clamping bolt.
According to Figure 1, a hand tool machine Mi the form of a jig saw 10 comprises a housing 12 having a top and bottom region 12a, 12b and a front and back region 12c and 12d. In its top region 12a the housing 12 carries a handle 14 which, in a region comfortably within reach of the operating hand, carries a switch button 16. The housing 12 centrally accommodates a motor 18 and a gear unit 20 coupled to the motor. The gear unit 20 converts the rotation of the motor 18 into an up-and-down motion of a lifting rod 22, which is supported vertically in a displaceable manner in the housing 12.
Thd'bottom end of the lifting rod 22 carries a releasably clamped saw blade 24 having saw teeth 25, which moves up and down with the lifting rod 22 during operation of the jig saw 10.
An electric cable 26 for supplying power to the motor 18 and an extraction connection piece 28 of an extraction channel 32 leading in the direction of the forward feed arrow 30 pass out of the housing 12 at the back region 12d of the jig saw.
The bottom region 12b of the housing 12 is supported by means of a supporting surface 34 on an abutment surface 36 of the top of a sole plate 38.
The supporting surface 34 runs straight in forward feed direction 30 and has a concave curvature. The abutment surface 36 of the sole plate 38 likewise runs straight in forward feed direction 30 but has a corresponding convex curvature.
The sole plate 38, which may be positioned with its underside J39 on a workpiece (not shown), comprises an opening 40 aligned with the saw blade 24 for passage of the saw blade 24 and, behind said opening, in the abutment surface 36 another opening 46 in the form of an oblong hole extending at right angles to the forward feed direction for the penetration of a clamping bolt 42.
The clamping bolt 42 engages from below through the opening 46 of the sole plate 38 with an external thread (not specifically designated) into an internal thread of a clamping nut 44, which is supported non-rotatably Mi the bottom region 12b of the housing 12. In the process, the clamping bolt 42 fixes the base plate 38 relative to the housing 12 in that said clamping bolt is clamped towards the edge of the opening 46 with a flange-like supporting plate 54 against the underside of the sole plate 38.
An eccentric head 50 is supported against the supporting plate 54 by means of a bearing pin 47, which defines the swivelling axis 48, supported against the clamping bolt 42. The eccentric head 50, which is capable of swivelling about the swivelling axis 48 extending at right angles to the forward feed direction, verges into a bar-like clamping lever 52. In the extension of the longitudinal axis of the clamping lever 52 the eccentric head 50 has at the front end no eccentric cam but at right angles to the longitudinal axis has at least one larger eccentric cam 1 a (Fig. 7).
In the illustrated position of the clamping lever 52, 'm which it extends parallel to the sole plate 38 and has the handle 56 directed towards the back region 12d, the eccentric head 50 of the clamping lever 52 is in its locking position, in which its eccentric cam 5 1 a presses the supporting plate 54 against the 9 1 1 6 underside of the abutment surface 36 and hence locks the sole plate 38 relative to the supporting surface 3)4 of the housing 12.
The clamping lever 52 is held fixed in its locking position in a frictionally engaged or positive manner by means of retaining ribs 58 of the sole plate 38.
In the back region, the abutment surface 36 of the sole plate 38 is curved upwards in a saddle-like manner and carries, like a row of teeth, uniformly spaced radial projections 62 and tooth-space-like recesses 63 (Figs. 3, 4), of which one projection 62 is visible. Associated with the projections 62 and recesses 63 are counterpart projections 62' and counterpart recesses 63', which are arranged like a row of teeth in the contour of the supporting surface 34 of the housing 12 and which through engagement one into the other serve to fix the housing 12 positively in adjustable angular positions relative to the sole plate 38.
The sole plate 38 is displaceable backwards relative to the housing 12 until the edge of the oblonghole-like recess 46 strikes against the clamping bolt 42. In said position, the projections 62 and recesses 63 are disengaged from the counterpart projections 62' and counterpart recesses 63' so that the sole plate 3 8 may easily be swivelled relative to the housing 12 when the clamping lever 52 is in its release position. The desired angular position between the sole plate 38 and the housing 12 is lockable by bringing the projections 62 and recesses 63 back into engagement with the counterpart projections 62' and counterpart recesses 63, (Figs. 3, 4).
Figure 2 shows an enlargement of an, in principle, identical further embodiment of the invention in the region of the sole plate 38 with a part of the housing 12 as well as with the clamping device comprising the clamping bolt 42, the clamping nut 54 and the clamping lever 52 with the eccentric head 50, wherein the clamping lever 52 - indicated by solid lines - is shown in its release position, in which after having been swivelled about the swivelling axis 48 it 7 projects down from the sole plate 38 and which allows an adjustment of the sole plate 38 relative to the housing 12. The dash-dot lines indicate the clamping lever 52 in its clamping position, after having been swivelled parallel to the sole plate 38.
To alter the clamping pressure between sole plate 38 and the housing 12, the clamping lever 52 has to be rotatedjointly with the clamping bolt 42 about its longitudinal axis in the direction of the clamping arrow 60 so that, by m' eans of an axial adjustment of the clamping bolt 42, the eccentric head 50 is also adjusted relative to the clamping nut 44 and so the clamping force in the clamping position is variable. In the clamping position of the clamping lever 52, the sole plate 38 is either clamped more tightly relative to the housing 12 or, in the event of rotation of the clamping lever 52 about its longitudinal axis counter to the direction of the rotation arrow 60, is clamped less tightly and, in the release position of the clamping lever 52, the sole plate and housing are mutually adjustable in a particularly smooth manner.
Figure 3 shows a cross section of the jig saw 10 according to Figure 1 in the region of the clamping lever 52, with the clamping lever 52 swivelled about swivelling axis 48 into the release position and with the handle 56 projecting downwards from the sole plate 38.
Figure 4 shows the same cross section as Figure 3 in a view from the front but with the clamping lever 52, of which only its eccentric head 50 is visible, swivelled (backwards) about the swivelling axis 48 in its clamping position parallel to the sole plate 38.
From Figures 3 and 4 it is evident that the abutment surface 36 of the sole plate 38 carries, like a row of teeth, uniformly spaced radial projections 62 and tooth-space-like recesses 63, associated with which is a plurality of counterpart projections 62' and counterpart recesses 63' arranged like a row of teeth in the contour of the supporting surface 34 of the housing 12, which through 8 is engagement one into the other serve to fix the housing 12 positively in adjustable angular positions relative to the sole plate 38.
Figures 5 and 6 show the inverted plan view of the sole plate 38 with the details previously described in the drawings, wherein the openings 40 and 46 for passage of the saw blade 24 and clamping bolt 42 respectively may be seen particularly clearly. Figure 5 reveals the clamping lever 52 swivelled about the swivelling axis 48 and projecting - out of the drawing plane - down from the sole plate 38. In Figure 6, the clamping lever 52 has been swivelled about the swivelling axis 48 into its clamping position parallel to the base plate 38 and has its handle 56 directed towards the back.
Figure 7 is an enlarged view of the detail of the clamping lever 52 with the handle 56 and with the eccentric head 50, wherein the external thread (not specifically designated) of the clamping bolt 42 and the flat part 43 of the latter with a drill hole 41 for passage of the bearing pin 47 are clearly visible.
Also visible as a detail is one of the two (Fig. 8) eccentric clamping surfaces 5 1 a of the eccentric head 50, which extend substantially parallel to the axis of the clamping lever 52, serve as eccentric cams and are indicated by dashdot lines, and with an eccentric release surface 5 lb extending at right angles to the axis of the clamping lever 52 and indicated by dashes at the front end of the clamping lever 52. The eccentric head 50 is shown partially in longitudinal section, wherein the flat part 43 of the clamping bolt 42 having the drill hole 41 for receiving the bearing pin 47 is visible.
In the position of the clamping lever 52 set parallel to the sole plate 3 8, the eccentric clamping surfaces 5 1 a of the fork-like eccentric head 50 are supported against the supporting plate 54 and hence press the abutment surface 36 of the sole plate 38 against the supporting surface 34 of the housing 12, with the result that the sole plate 38 is firmly clamped relative to the housing 12.
9 In the position of the clamping lever 52, in which it projects at right angles down firom the sole plate 38, the radially flirther Miward-lying release surfaces 5 lb are supported with reduced force against the supporting plate 54, with the result that the pressure between abutment surface 36 of the sole plate 38 and supporting surface 34 of the housing 12 lessens in such a way that the sole plate 38 may easily be adjusted relative to the housing 12.
Figure 8 shows the longitudinal section through the clamping lever 52, connected to the clamping bolt 42, according to Figure 7 parallel to the sole plate 38. Here, it is particularly clear that the clamping lever 52 in the region of the eccentric head 50 is of a fork-like design and embraces the end of the clamping bolt 42 M" the form of flat part 43 on both sides. The bearing pin 47 in the form of a nivet, which defines the swivelling axis 48, passes through the eccentric head 50 as well as the end of the clamping bolt 42 directed towards it. The bearing pin 47 is non-rotatably supported by the fork-like end of the eccentdc head 50, while the clamping bolt 42 is easily capable of swivelling relative to the bearing pin 47.
