Definitions
- the invention relates to a wall slot device according to the preamble of the claim 1.
- From DE-OS 195 11 725 is a wall slot device with a carriage and one known pivotally arranged on the carriage housing.
- the housing is fixable during the slitting process at a depth stop along a adjustable from the slide in the direction of the housing locking rail is arranged. With this determination, a lifting of the housing from the Depth stop or a change in the inclination of the housing relative to the Carriage prevented so that the slots have a constant depth.
- One of a locking switch is used to fix the housing on the slide rotatable, arranged in the housing pawl and a the pawl cooperating locking arm.
- This locking arm is part of the depth stop and protrudes from it towards the housing.
- the locking arm is positively connected to the pawl rotatably mounted in the housing can be brought in if this is due to the actuated locking switch a release position opposite the locking rail.
- the housing is attached to the depth stop and the depth stop is adjustable compared to the locking rail, there is a possibility that it improper handling of the wall chaser to adjust the Depth stop can come in such a way that the preselected depth of cut changes can change.
- the invention has for its object a safe and easy to operate wall slot device to create, in which the preselected depth of cut changes during the slitting process cannot change when the interlock switch is actuated.
- the housing and the carriage Due to the direct fixing of the housing on the locking rail of the Carriage, the housing and the carriage can not be swung apart as long as the locking switch is operated.
- a secure and quick fixing of the housing on the locking rail is advantageously achieved by means of a locking arm, the at least one projection has the form-fitting with a recess of the locking rail in Connection can be made.
- the recess of the locking rail is, for example, of a toothed Area formed in which several teeth in the longitudinal extension of the locking rail are arranged one behind the other. So that the projection of the locking arm when Swiveling the housing on the one hand in relation to the locking rail Recess or the spaces between the teeth of the locking rail can snap into place, on the other hand during the pivoting movement of the housing Slide is pushed out of the recess each time it hits a tooth, the projection preferably has a stop surface facing away from the slide and a guide surface facing the slide, the stop surface extends substantially perpendicular to the longitudinal extent of the locking rail and the guide surfaces towards the free end of the projection in the direction of the stop surface is inclined.
- the locking arm is at least advantageously partially arranged in the housing.
- the locking arm is expediently accommodated at least one bearing point of the housing around which the locking arm is pivotable.
- the pawl To pivot the locking arm from the locking position in the Release position at the same time as the pawl is turned into the locking position To be able to reach, the pawl has one with the locking arm interacting control curve.
- the wall slot device shown in Fig. 1 consists of a housing 10, one with the housing 10 connected drive unit 20 for at least one a disc 50 existing slot tool 40 and a slide 30 together.
- the housing 10 is parallel to the plane of the disk Slotted tool 40 around one arranged in a first end region of the device Bearing 34 pivotable against the force of a spring 36.
- rollers 31 In the corners of the sled 30 are arranged rollers 31, the better displacement of the carriage 30 on a to be processed underground U.
- the rollers 31 are arranged in such a way that moving the carriage 30 or the entire device only parallel to Slice plane of the slot tool 40 can take place.
- the housing 10 Both in the first end region connected to the slide 30 via the bearing 34 and also in a second end region, the housing 10 has a protruding portion Handle 11.13.
- the handle 11 arranged in the first end region of the device has an electrical switch 12 with which the drive unit 20 can be actuated.
- the one in the second Handle 13 arranged in the end region of the device has a locking switch 14 which, when actuated, limits the pivoting movement between the housing 10 and slide 30 serving locking device 15 activated by a pawl 151st is rotated against the force of a spring element 17. In the locked position of the Pawl 151 - the locking switch 14 is not pressed - is supported, as in FIG.
- a clamping area not shown having depth stop 33 arranged along this locking rail 32nd is gradually adjustable.
- the clamping area acts positively with at least a recesses 321 of the locking rail formed by a toothed region 32 together.
- the depth stop 33 can be set to a desired slot depth become.
- the pawl is actuated when the locking switch 14 is actuated 151 about an axis of rotation 103 of the housing 10 with the aid of a transmission element 16 rotated from a locking position into a release position.
- the locking surface 153 arranged on the pawl 151 gives the locking rail 32 free and the housing 10 can 32 in the direction of the locking rail or be pivoted in the direction of slide 30.
- a limiting surface 101 of the housing faces the depth stop 33 10 on a stop surface 331 of the arranged on the locking rail 32 Depth stop 33 for the system, as shown in Fig. 4, is carried out Fixing the housing 10 on the set to the desired slot depth Depth stop 33 as long as the locking switch 14 is operated. The device is thus in a working position and the discs 50 of the slot tool 40 project beyond the side of the slide facing the surface U to be machined 30 by the amount that can be read from the setting scale 35.
- the housing 10 is fixed on the depth stop 33 with the aid of a Bearing point 102 of the housing 10 is arranged pivotably in the direction of the slide 30 protruding locking arm 18 which with the locking rail 32 form-fitting is connectable.
- This positive connection is used on the Locking arm 18 arranged projection 181 with one of a toothed Area of the locking rail 32 formed recess 321 can be connected is.
- the projection 181 is located on one of the bearing points 102 of the housing 10 opposite free end region of the locking arm 18 and has one of the stop surface 182 facing away from the slide 30 and a stop face facing the slide 30 Guide surface 183.
- the stop surface 182 extends essentially parallel to the disk plane of the slot tool 40 and perpendicular to the longitudinal extent of the Locking rail 32.
- the free end of the locking arm 18 is from the Guide surface 183 is formed, which towards the free end of the projection 181 Stop surface 182 is inclined and the stop surface 182 at an acute angle cuts.
- the locking arm 18 acts with a spring part 19 designed as a wrap spring together, which is arranged at a bearing 102 of the housing 10.
- a first Free end region of the spring part 19 is supported on a stop edge 104 of the Housing 10-ab and a second, free end area also presses the locking arm 18 its projection 182 towards pawl 151.
- Fig. 2 shows the locking device 15 in an initial position of the wall slot device.
- the locking switch 14 is not pressed and the free end of the locking rail 32 is located on a locking surface 153 which is in the locked position pawl 151 located.
- the control curve 152 of the pawl 151 presses the Locking arm 18 away from the locking rail 32.
- the pawl 151 is in a release position is located and the housing 10 is pivoted somewhat in the direction of slide 30.
- the locking arm 18 bears with its projection 181 on the locking rail 32.
- the partially inclined guide surface 183 prevents a firm engagement of the locking arm 18 in the recess 321 of the locking rail 32.
- Fig. 4 shows the locking device 15 in a working position of the wall slot device.
- the boundary surface 101 of the housing 10 lies on the stop surface 331 of the Depth stop 33 and the projection 181 of the locking arm 18 protrudes into the Recess 321 of the locking rail 32.
- Locking device can control cam 152, for example, on locking arm 18 issue.
