    TECHNICAL FIELD The present invention relates to a handheld rock drill with a feed leg. The feed leg is with one spirit attached to the rock drilling machine and rests with the other spirit against an underlay. The feed leg is designed to feed the rock drilling machine in a drilling direction or to interrupt the feeding of the rock drilling machine in the drilling direction. A control is provided for controlling the feed leg and a pad pull is provided for activating the rock drilling machine. . The feeder leg is with one spirit fixed approximately in the middle of the rock drill, while the other, opposite spirit has Lex. a foot with the help of which one takes the spear against the ground. The feed leg usually consists of a cylinder tube, a piston, a piston rod, controls and means for guiding a pressure medium to and into the cylinder tube on each side of the piston therein. Depending on which side of the piston the pressure medium is controlled, the piston rod is driven out of the oil into the cylinder tube. The feed leg can be driven pneumatically or hydraulically. The slider for the roller leg is traditionally located directly on the feed leg, but there are also other solutions, and a pad for the rock drill on top of it, which means that you can not reach the sliders without moving your hands between them. start the rock drill at the same time as lifting the rock drill to position the drill. This can be difficult to achieve with the feed leg control and the pawl for the rock drilling machine at a distance from each other, P554409EN00 2 SUMMARY OF THE INVENTION can be maneuvered with one and the same hand without moving the hand.

    DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT The present invention relates, as stated above, to a handheld rock drill with a feed leg. A hand-held rock drilling machine of older design is schematically illustrated in Fig. 1. The rock drilling machine is indicated in Fig. 1 generally by 1. A feed leg 2 years via e.g. a gooseneck coupling 3 with one end fixed to the underside of the rock drilling machine 1, so that the rock drilling machine can move, i.e. turned and rotated in relation to the feed work. Other types of lamp couplings can also be used. The feed leg 2 is used to provide standing At the rock drilling machine 1 and to provide feed power and counteract reaction forces from the rock drilling machine when drilling. The second spirit of the feed leg 2, the centered spirit which is connected to the rock drilling machine 1, can thus be designed towards e.g. a foot of a suitable type to support the rock drilling machine in the best way and with the help of which you can take struts against the surface on which the rock drilling machine rests via the feed leg.
    As mentioned, the feed leg 2 is designed to feed the rock drilling machine 1 in a drilling direction during drilling, but also to interrupt the feeding in the drilling direction of the rock drilling machine if necessary. The feed in the drilling direction of the rock drilling machine 1 is interrupted e.g. d the feed leg 2 must be moved for retrieval or cla drilling will no longer take place. The feed leg 2 in and of itself in the main body known construction comprises the embodiment shown in Figs. 2 and 3 a cylinder root. 4. The cylinder tube 4 is closed in the duct portions by means of end caps 5 and 6, of which the end piece 5 has the gooseneck coupling 3 for connection to the rock drilling machine 1. A piston 7 is displaceable1 arranged in the cylinder tube 4. The piston 7 defines a space 8 and 9 for a pressure medium in the cylinder tube 4 on each side of the piston. A seal 10 is arranged on the piston 7 to prevent the pressure medium from flowing from one to the other space 8, 9 by passing between the piston and the inside of the cylinder tube 4. The seal consists e.g. of a 0-ring of suitable material. The feed leg 2 also comprises a supply means 24 (see Fig. 7) for guiding the pressure medium to the spaces 8, 9 in the cylinder tube 4. A control 11 by means of which the pressure medium is directed to the space 8 or 9 for the pressure medium on one or the other side of the piston 7 is arranged on the rock drilling machine 1, in the embodiment shown according to Fig. 1 at the rear of the machine. Due to the action of the pressure medium on the piston, a piston rod 12 connected to the piston 7 is displaceable out of and into the cylinder tube 4, respectively, in order, as indicated above, to feed the rock drilling machine 1 in the drilling direction and to interrupt the supply of the rock drilling machine. The piston rod 12 then proceeds PS54409SE00 4 out of the cylinder tube 4 via an opening 13 in the end piece 6. A lamp seal 14 is also provided in the opening 13 to prevent the pressure medium from flowing out of the outlet rim 9 by passing the piston rod 12 and the opening. The piston rod 12 5r in its outer end% outside the cylinder tube 4, provided with a support e.g. in the form of two legs in Figs. 2 and 3. However, the number of standing legs may vary. There are variants with one leg, but also with four legs 15, as in Fig. 1. The pressure medium can be retrieved from a pressure medium cold 25 (see Fig. 7) and the pressure medium is fed to the feed leg 2 e.g. via the control 24, the coupling 3 and the end piece 5. The pressure medium supplied there normally has a pressure of approx. 5 bar. The pressure medium can also be used for cooling the rock drilling machine during operation, flushing out drill cuttings, etc .. Filling of pressure medium on the pressure medium source 25 can take place via e.g. a filling line 26. The filling line 26 can alternatively be connected directly to the control 11. A path 16 for activating the rock drilling machine or for interrupting this activation is arranged in Fig. 1 on top of the machine. In Figs. 4-6, according to the present invention, the control 11 for the feed leg 2 and the pad 16 for the rock drill 1 are arranged in a different manner than in Fig. 1 to facilitate the maneuvering of the feed leg and the rock drill. As shown in Figs. 4-6, the control 11 is for controlling the feed leg 2 for feeding the rock drilling machine 1 in the drilling direction and for interrupting the feeding of the rock drilling machine in the drilling direction or, in other words, for controlling the pressure medium to the respective space 8, 9 on it. one or the other side cm of the piston 7 for displacing the piston rod 12 out of and into the cylinder tube 4, now formed on a rear handle 17 of the rock drilling machine in close connection to the pad 16 of the rock drill so that said controls and said pad pull can be reached simultaneously with one hand to activate or interrupt the activation of the rock drilling machine at the same time as the feed leg is controlled to feed the rock drilling machine in the drilling direction and interrupt the feeding of the rock drilling machine in the drilling direction, respectively.
    The embodiment shown in Fig. 4 is designed as a rotary knob 11 which is rotatably mounted on the handle 17, i.e. rotatable about an axis A which extends centrally through the handle 17 in its longitudinal direction. However, the control 11 can also have another form suitable for the spirit. The handle 17 extends between and is mounted at Iva shanks 18 to the back of the rock drill 1. The legs 18 are advantageously designed so that they form protection for the control 11, the pawl 16 and the operator's hand around the handle 17. The pawl 16 for the rock drilling machine 1 is in turn pivotally mounted on a portion 19 of the back of the rock drill 1 projecting slightly between the said shanks 18 inside the handle 17 PS54409SE00 with the rotary knob 11, ie, in the intended drilling direction seen between the back piece and the handle. The pad pull 16 is pivotable about an axis B which runs through said portion 19 of the back piece. The pad pull 16 comprises an arm 20 which is designed to be pivotable about the axis B so that the arm is manually displaceable from a starting position shown in Figs. 4 and 5, in which the rock drilling machine 1 is not in operation, in the direction of the rock drilling machine for activating it, and the rotary knob 11 For the feed leg 2 is arranged substantially immediately over or obliquely over and forward at least a part of the arm when it is in the starting position, e.g. some or a few centimeters Over or obliquely Over and in the intended drilling direction seen in front of the arm or the said part clarav da armen inter startlage, i.e. that the rotary control m.a.o. is located between the handle and the arm and advantageously at such a distance from the arm that the operator's hand fits between the arm and the handle with the rotary knob.
    The arm 20 may be formed bias in the direction of the starting team, but is not normally.
    In the extension shown in Figs. 4-6, the arm 20 is pivotally mounted at the portion 19 of the back piece substantially centrally on the arm, to form two arm portions 20a and 20b, a lower and an upper arm portion on each side of the pivot axis B, since the arm displacement around the axis B moves in opposite directions. The lower arm portion 20a is located in the starting layer shown in Figs. 4 and 5 at least partially below or obliquely below and in the intended drilling direction seen behind the rotary knob 11 for the feed leg 2 in the immediate vicinity of the rotary knob, i.e. right next to or only a few centimeters from the rotary knob, and can thereby, as desired, be biased towards the starting team ph suitably set. In order not to take up too much space, the arm can be designed so that the portions 20a, 20b bend at an angle in relation to each other, which in Figs. 4-6, according to which the lower arm portion 20a is angled once more to optimally close the handle 17 with the rotary knob 11 and in optimal position in relation thereto. This meant, for example, that the lower arm portion 20a of the starting layer is at such a distance from the rotary control 11 that the operator can get his thumb or forefinger between said arm portion and the control or even a even shorter distance from the control when the lower arm portion at least partially projects below or obliquely down below and in the intended drilling direction seen behind the control To such an extent that it Or made accessible to the operator. In the starting layer according to Figs. 4 and 5, the upper arm portion 20b can assume a position, for example approx. 5-8 centimeters from the rotary knob 11 or resting against the back piece, inside the handle 17 with the rotary knob 11, the starting layer also being determined for the lower arm portion 20a Or. Upon full activation of the rock drilling machine 1 according to Fig. 6, the Owe arm portion 20b can assume an [age atmin- tone partly Over or obliquely Over and In the drilling direction seen behind the rotary knob 11 in immediate PS54409SE00 6 proximity thereof, i.e. a few centimeters (for example approx. 3-5 centimeters) from the rotary knob and between this and the rock drill. The lower arm portion 20a can then be approx. 4-7 centimeters from the rotary knob 11.
    Without moving the hand away from the handle 17 and the pivotally arranged control 11 for the feed leg 2, the pad pull 16 for the rock drilling machine 1 thus becomes accessible to the rock drilling machine as well. The operator only needs to move the thumb or forefinger from the rotary knob 11 to the arm 20 to the pad pull 16, e.g. to the lower part 20a of the arm, and push the arm / - / arm part in the direction of the rock drilling machine, for example to the team according to Fig. 6 which shows the pad pull 16 when the rock drill is fully activated or to a layer somewhere between the starting team and the team at full activation.
    The arm 20 / arm portion 20a can be formed with guide means, e.g. a guide pin 21 which runs a groove 22 in at least one shank 18 to the rear of the rock drilling machine 1. This purpose of controlling and thereby stabilizing the pad pull 16 / arm 20 during the displacement thereof. The guide pin 21 is also connected to a long arm (not shown) which acts on a valve for all activating and deactivating the pad The traction 16 can, as indicated above, be biased towards the starting layer according to Figs. 4 and 5.
    Delta can take place via the guide pin 21 or the lane arm in connection therewith and a spring member or the spring arm acting on spring means. The guide pin 21 or the link arm can be e.g. compression or tension spring loaded against the starting team. Alternatively, the pad pull 16 may be biased towards the starting layer according to Figs. 4 and 5 by means of e.g. a spring member (not shown) arranged on suitable salt adjacent to the pivot axis B for its action. The spring member can be e.g. a spring arranged at or around a pivot axis B forming a pivot pin (not shown) on the arm 20, by means of which the arm is mounted in the portion 19 of the back piece of the rock drilling machine 1. Another alternative is that the upper arm portion 20b is formed with a counterweight (t e.g. at 23) which by its weight pulls back the Owe arm portion 20b substantially in the drilling direction and arms fer the lower arm portion 20a substantially in the opposite direction, back towards the starting layer according to Figs. 4 and 5. The Upper arm portion 20b / the counterweight can then be brought into the starting layer against the back piece of the rock drilling machine 1. In order for the design to work with a counterweight & potassium, it is important that it never slides between the pivot axis B of the arm 20 and the handle 17 with the rotary control 11.
    However, as stated above, the arm 20 is not normally biased towards the starting layer so that when drilling into it one must constantly press the arm or the lower arm portion 20a in the direction of the rock drilling machine to keep the machine running. The part denoted by 23 of the lower arm portion 20b can then instead be designed to facilitate return of the arm to the starting layer by pushing said arm portion substantially in the drilling direction without having to relax the grip on the handle 17 with the rotary knob 11. This is mopig through all the the lower arm portion 20a when the arm 20 is pivoted, the frame is brought away from the handle 17 by the rotary knob 11, the upper arm portion 20b being displaced towards the handle with the rotary knob. With a straight design on and / or angled of the arm portions 20a, 20b in relation to each other, e.g. with an angle in the embodiment shown in Figs. 4-6 of approx. 800 or slightly more than 80 ° at the pivot axis B, the upper arm portion 20b can be shown in part in Figs. 4-6, thereby coming slightly closer to the rotary control 11, as stated above, for example only a few or a few centimeters from this. Alternatively, if this is more easily dependent on the position of the lower arm, the arm 20 at the bottom or the lower arm portion 20a can be designed so that e.g. with the thumb or forefinger allowed to grip the arm to retract it in the direction of the handle to the starting layer without having to relax the grip on the handle 17 with the rotary knob 11. For example, the arm 20 at the bottom or the lower arm portion 20a to facilitate this fames with one or several surfaces 20aa of ordinary material. Avon the upper arm portion 20b can be famed with one or more surfaces 20ba, 20bb of ordinary material.
    The function of the embodiment of the feed leg 2 described above and shown in the drawings is as follows, with reference to Fig. 7 in particular: When the rock drilling machine 1 is to be fed in the bar direction, the flow is controlled by the pressure medium by means of the rotary knob 11 so that the pressure medium from the pressure medium source 25 or directly Iran the supply line 26 via at least one supply channel or line 24a and via at least one channel or line 24b to the supply means 24 flows into the space 8 on the side cm piston which is water towards the rock drilling machine, but not into the space 9 on the sicia am piston that is water away from the rock drill. The rotary control 11 occupies a position where the flow of pressure medium through the same path as schematically shown in the upper part thereof in Fig. 7. This means, relatively speaking, that the piston 7 and thus the piston rod 12 of the pressure medium is displaced out of the cylinder tube 4 in one direction away from the rock drill 1. With the undone of the feed leg 2 as an abutment, the cylinder tube 4 is thus pressed in the opposite direction to the rock drill 1 and the rock drill is driven by means of the cylinder tube in the drilling direction. The space 9 is simultaneously connected to at least one discharge channel or line 24c via PS54409SE00 8 at least one further channel or line 24d to the supply means 24, or to the pressure medium channel 25 via these channels.
    If, on the other hand, the feeding of the rock drilling machine 1 in the drilling direction is interrupted to allow movement of the feed leg to take over or to end all drilling, the rotary knob 11 is adjusted so that the pressure medium flows out of the space 8 via the duct 24b. via the supply channel 24a and the further channel or line 24d to the supply means 24 is guided into the space 9 on the side of the piston which is water away from the rock drilling machine. The rotary control 11 assumes a position where the flow of pressure medium through the same path is shown schematically in the lower part of the drive shaft in Fig. 7. This means, relatively speaking, that the piston 7 and thus the piston rod 12 of the pressure medium are pushed into the cylinder 41 towards the rock drill. 1. The feed leg 2 is thus contracted and the rock drilling machine can be taken out of the occupied borehole if drilling is to be completed or the feed leg can be moved for retrieval.
    If drilling is to take place again or after reassembly, the rotary knob 11 is rearranged so that the pressure medium flows out of the space 9 via the channel 24d and the discharge channel 24c and the flow of the pressure medium is again directed into the space 8 via the supply channel 24a and the channel 24b.
    The discharge channel 24c may be connected to the pressure medium source 25 for reuse of the pressure medium in question.
    Adjustments of the rotary knob 11, as well as maneuvering of the pad pull 16, at pahugg saval corn during drilling, are easily feasible with one hand by means of a rock drilling machine of the method described above.
    It will be apparent to one skilled in the art that the rock drilling machine according to the present invention may be modified and modified within the scope of the appended claims without departing from the spirit and spirit of the invention. Thus, as mentioned, the control 11 can be designed in another way than as a rotary control. Padraget 16 can also be formed on other salt. Part is dachshund. it is obvious that the traction 16 does not have to be designed as an angled arm 20, but the arm can also be straight and also pivotally mounted in one spirit thereof. In such an embodiment, it is important that the arm 20 is accessible to all teams, if the same is not the father of the starting team. If amen 20 is angled, the angle can vary to a large extent and the different arm portions 20a, 20b can also be designed and / or angled further to save space and for! make sure that the positions of the arm PS544095E00 9 parties in relation to the handle 17 with the rotary knob 11 are ergonomically as good as possible and, if the arm is not biased towards the starting team, at least one of the arm parts is easily accessible to all teams on the arm from the starting team to the team at full activation of the rock drilling machine 1.
