Definitions

  • This invention refers to a handsaw comprising an elongated blade with a line of teeth, the individual teeth of which are provided with such edges that will make sawing in a rearward direction more efficient than in a forward direction, and a handle, including an elongated handgrip of shorter length than the blade and an attachment part extending in a generally blunt angle against the handgrip and being attached to a rear portion of the blade by a joint permitting rotation of the blade relative to the handle and co-operating with a locking mechanism including a locking member insertable into one of a multitude of periferically separated recesses within a generally semi-circular rear edge part of the blade to facilitate locating of the blade in different angular positions relative to the handle, said handgrip including two side walls connected by a common back and delimiting a first slot ar- ranged to co-operate with a second slot in a tooth protector movable between an inactive position and an active position extending in the direction of the handgrip and in which position the line of teeth of the blade can
  • a separate sheath is used, which is delivered and carried together with the handsaw.
  • One disadvantage of said handsaw is precisely the need of a separate sheath or tooth protector, which makes it expensive to manufacture and is liable to become lost under various circumstances.
  • the applicant has developed a handsaw where the tooth protector needed is made as an integral part of the handsaw.
  • This saw is basically designed as described in the introduction and it is further described in the patent application SE 9803675-9.
  • the tooth protector is made as a lid part with a U-shaped cross section, one end of which is hingedly connected to the free lower end of the handgrip part of the handle, which has also a U-like cross section, at least partially.
  • the lid part can be rotated between a first active position as an exten- sion of the handgrip, allowing the blade and its teeth to be inserted in the slots formed in the handgrip and the lid part by their U-shaped cross sections, and a second inactive position where the lid part encloses the handgrip.
  • the handsaw is primarily intended for pruning. For that reason the handsaw is made in such a way that the blade can be located in only two different angular positions relative to the handle, specifically one operative position at an angle of 130 to 135 degrees from the handgrip, and secondly an inserted position at a very small angular difference from the handgrip with its lid part unfolded.
  • the rear end of the blade is provided with two recesses co-operating with the locking mechanism of the handle, specifically a first recess situated at a lower edge of the blade and a second recess at an angular distance of 130-135 degrees from the first recess.
  • the present invention aims at improving the handsaw described in SE 9803675-9 in such a way that it can be used efficiently not only for pruning pur- poses, but also and primarily for general carpentry purposes.
  • One basic aim of the invention is thus to create a handsaw of the general kind described above, but possible to be used not only in such situations where the handle and the hand gripping it are clearly distanced from the work piece (as is the case when cutting separate lengths of lumber, tree branches or similar) but also for flush cutting when the handle and the hand move in the immediate proximity of a support surface (as in the case of cutting wooden laths supporting tiles on a roof). Efficient sawing and ergonomic suitability should be ensured independently of for what purpose the saw is used for a given angular setting.
  • the invention also aims to provide a handsaw with an improved tooth protector.
  • German petty patent DE 29613265 U1 describes a handsaw with a handle designed without knuckle protection, rotatable to a position obliquely upward-rearward from the rear end of the blade, in order to permit sawing through a workpiece on a supporting surface. In that case, however, the sawing capacity will be mediocre, since the handle will subject the blade to an upward force vector during every rearward sawing motion when the necessary pulling force is applied to the upwardly directed handle.
  • Another embodiment of the saw has a knuckle protection and may be used for sawing through a workpiece on a support, but in that case the knuckle protector extends below the straight line of motion of the teeth of the blade; something that will make sawing all the way through the workpiece impossible.
  • US 2747631 describes a handsaw comprising a handle which is built from a sturdy handgrip and a comparatively slim attachment part, and a blade con- nected to the attachment part and adjustable to different angles relative to it.
  • the different setting positions of the blade are determined by a multitude of equidistant pins located on the attachment part and penetrating a number of equidistant holes in the blade and in a locating body which is connected to the at- tachment part by a threaded bolt device pressing the blade against the attachment part.
  • the locating body In order to adjust the blade between different angular setting positions, the locating body must be released and them remounted after the pins determining the setting positions having been inserted in the desired series of holes.

  • Figure 12 is an enlarged partial lateral view of of the rear end portion of the blade
  • Figure 13 is an enlarged partial lateral view showing the type of tooth line of the blade.
  • the handsaw according to the invention shown in various positions in figures 1 - 5 comprises a handle 1 , a blade 2 and a tooth protector 3.
  • the blade 2 carries teeth 4 forming a line of teeth which preferably is straight and in its details complies with what is shown in figure 13.
  • the line of teeth includes sets of two different tooth types 5, 6, some of which are longer than others. More particularly, the tooth line includes sets of two or more long teeth 5 separated by a short set tooth 6. Each long tooth 5 is ground with a rear cutting edge 7 with a rake angle ⁇ equal to 12 degrees, while the relief angle ⁇ of every front cutting edge equals 24 degrees. The cutting edges are sharply ground and terminate at a sharp point. Since the rake angle ⁇ is considerably smaller than the relief angle ⁇ , the rear cutting edges 7 will cut considerably more aggressively than the front cutting edges 8; which in practical applications means that the main part of the sawing action is performed when the blade is pulled rearwards.
  • the shorter tooth 6 between adjacent sets of longer teeth 5 is ground with a top relief angle ⁇ which may be about 32 degrees.
  • the long teeth can have a length of 4.8 mm, where the difference in length between long and short teeth may be 0.8 mm. After grinding of respective cutting edges, the short teeth 6 are set to improve chip removal.
  • the handle 1 as shown in figures 1-5 comprises an elongated handgrip 9 as well as an attachment part (10 as a whole), which basically extends in a blunt angle to the handgrip 9 and onto which the blade 2 is attached, specifically by means of a joint 11.
  • Said blunt angle is defined as the angle where a basically flat or linear top surface 12 cuts a conceived centre line 13 through the handgrip 9. In the embodiment shown, this blunt angle amounts to approximately 135 degrees, but may be in the region 130-140 degrees.
  • a rear portion 14 without teeth of the blade 2 is inserted in an open slot 15 in the attachment part 10, see figures 9-11 , and is attached to this by the joint 11 , which may be realised as a simple pin or bolt extending across the slot 15.
  • a locking mechanism 16 is provided, comprising a cylindrical pin 17 with a head 18.
  • the pin 17 is located in a bore 19 extending through the attachment part 10, specifically at right angle to the slot 15.
  • the pin 17 is in a known way provided with two axially separated constrictions 20,21 with different size diameters.
  • the rear end portion 14 of the blade 2 is essentially semi-circular, where in the semi-circular peripheral re- gion 22 are cut four separate recesses 23, 24, 25, 26, the locations of which are described below.
  • Each such recess has a partially circular shape, the diameter of which corresponds to the diameter of the larger constriction 21 of the pin 17.
  • the pin 17 is normally held in an outer end position by a spring 27, with the larger constriction 21 in the same level as the slot 15, whereby the pin locks the blade in a desired angular position when it engages with one of the recesses 23-26.
  • the pin 17 When the blade is to be released to be rotated, the pin 17 is pressed into the bore 19 against the force of the spring 27 to a position where the narrower constriction 20 is located in the plane of the slot 15.
  • This constriction 20 has a diameter small enough in comparison to the depth of the actual recess to create a distance be- tween the pin and the recess, allowing the blade to be rotated away from the actual recess.
  • the first recess 23 is located at a straight edge portion 28 which at one end meets the tooth line 4 and at its opposite end merges into the semicircular edge 22.
  • the recess 23 is located near the transition between the straight edge 28 and the semi-circular edge 22.

  • the actual distance between the conceived extension line L and the front end of the straight edge 28 is about 8 mm when the height of the teeth 4 is 4.8 mm as said above.
  • a second recess 25 which determines the most common operative position of the blade is peripherally separated from the first recess 23 by an angle of about 134 degrees.
  • a third recess 26 is also provided, separated from the second recess 25 by about 40 degrees. Further, between the first and second recesses 23, 25 is provided a fourth recess 24 separated from the first recess by about 99 degrees.

Analogously, the angle ⁇ may be other than 35 degrees but within the range of 30-40 degrees, and the angle ⁇ may be within the range of 35-45 degrees. In all cases the total angle between the first and third recesses 23, 26 should be within the range 170-180 degrees. In the shown preferred embodiment the total angle between the first and third recesses 23, 26 amounts to 176 degrees.
  • the blade 2 has an upper edge 29. In the rear region of the blade this upper edge 29 is approximately parallel to the tooth line 4 and the line L extending from the tooth tips.
  • Figures 5 and 9 show the basic geometrical shape of the attachment part 10 of the handle.
  • the handgrip 9 merges into the attachment part 10 through a comparatively slender transition portion 30 which at its inner border has a softly rounded recess 31 adjoining a thickened rear portion 32 of the attachment part 10.

Both these halves are made with convexly curved outsides and flat insides which are pressed together when the two halves 42, 43 are to be united by a suitable method such as gluing or welding. On the flat inside, each half 42, 43 is provided with an elongated recess 44 which is open towards the free lower end of the handgrip 9. Together, the two recesses 44 in the respective halves 42, 43 form the cavity 41 mentioned above. At the bottom of each recess is provided a groove 45 ending at a certain distance from both ends of the handgrip 9.

  • the hinge device serves to allow connecting of the saw to a garment-mounted holder clip of the kind described in WO 99/20909 which includes a keyhole-shaped recess into which the hinge device can be hooked and which allows the saw to swing relative to the holder clip, and which allows easy disconnection of the saw from the holder.
  • One of the handgrip part halves 43 is provided with a cut-out 50 to receive the hinge device 47.
  • This cut-out 50 is open at the free end of the handgrip and is provided with a retaining bump 51.
  • the narrow neck 49 of the hinge device 47 enters the cut-out 50 and is snapped in place by the bump 51 which fits into a pit-like recess 52 in the hinge device.
  • the described snap connection ensures that the slide is retained in the corresponding cavity when the saw is actively used for sawing. However, the snap connection does not produce a noticeable resistance to pulling the slide out to the actively protecting position shown in figures 2 and 5.

  • the tooth protector 3 has been pulled out from the handgrip part of the handle, and the blade 2 has been folded into the tooth protector as well as the handle itself, thereby ensuring a good protection of and from the sharp teeth of the blade.
  • the locking pin 17 is located in the first recess 23.
  • a characteristic of the invention is that the third recess 26 makes it possible to locate the blade in the position shown in figure 4.
  • the handgrip part 9 of the handle extends from the attachment part 10 rearwards in a direction obliquely downward relative to the extension line L from the tooth tips.
  • the handgrip 9 forms an angle of about 8 degrees (may vary within the range 6-10 degrees) with the extension line L. Since the attachment part 10 forms a blunt angle within the range 130-140 degrees relative to the handgrip 9, the rear end of the handgrip 9 will keep a distance from the extension line L in spite of the fact that the handgrip slopes downward and rearward from where its front end merges into the attachment part 10.
  • the handsaw can in this state be used for flush sawing, such as for crosscutting of a workpiece resting on a support surface such as a roof laths. Since the entire handgrip 9 has a good clearance from the support below, the fingers of the hand can fit around the handgrip part without rubbing against the support surface. The good clearance is greatly improved by the fact that the attachment part 10 is made with a forwardly tapering shape, as said above. This implies that the underside 34 of the attachment part in the state shown in figure 4 is localised at a notable distance from the extension line L.
  • the handsaw described which according to the invention includes a fourth recess 24 between the first and second recesses 23, 25 it is also possible to locate and lock the blade in the position shown in figures 1 and 2. In that state, the blade form an angle of about 99 degrees with the handgrip part of the handle.
  • This functional state is especially suited for pruning purposes, with special regard to the possibility to turn the saw upside down for sawing partially through the underside of a branch as is commonly done when cut- ting thick branches. Although the saw has been turned with the teeth upwards, a considerable pulling force will still be applied to the blade since the handle forms such a steep angle with the blade.
  • One major advantage of the handsaw according to the invention is that it is universally useful not only for pruning but even more importantly for general carpentry purposes, especially for flush cutting as has been described above with reference to figure 4.
  • an efficient transfer of the user's muscular force through the handle to the blade is ensured, while at the same time the hand is protected from mechanical damage, in part by the knuckle guard of the handle, in part by the geometrical relation of the handle relative to the blade.
  • the tooth protector described also offers a good protection for and against the teeth of the blade. It should be especially stressed that the tooth protector described permits use of the same handle of a standard design together with blades of different lengths. To adjust the useful length of the tooth protector to blades of different lengths, the only needed simple measure is to provide retaining elements 26 at suitable different distances from the free outer end of the tooth protector.

Abstract

L'invention concerne une scie à main comprenant une lame (2) dotée d'une denture (4), et une poignée (1) dotée d'une partie préhension (9) et d'une partie fixation (10) formant un angle arrondi avec la partie préhension. La lame peut se trouver à différents angles par rapport à la poignée à l'aide d'une articulation (11) et est pourvue d'un certain nombre d'évidements séparés périphériquement dans lesquels le pivot (17) d'un mécanisme sollicité par ressort peut être inséré. Dans une position verrouillable sur quatre, la partie préhension (9) de la poignée s'étend de la partie fixation (10) jusqu'à l'arrière avec une pente négative par rapport à une ligne L s'étendant à partir de la denture (4) de la lame. Cela permet à la partie préhension (9) d'être à une bonne distance d'une surface d'appui adjacente de la pièce à traiter. Dans une autre position, la main de l'utilisateur peut appliquer une force de traction vers l'arrière, ce qui permet d'obtenir une composante de force descendante qui plaque les dents de la lame dans le fond de l'entaille sciée.
