Description

due to its 455 895 v 2 any risk of the heating pipe being damaged by the holders. The guide recess for the heating tube also facilitates the placement of the device, since a laborious focus according to eye measurements is not needed.

It is particularly advantageous to place the carrying handle on the impact device (claim 2), even if such embodiments also fall under the invention, in which the carrying handle is placed in another way. A device according to claim 2 is particularly simple, since then you only have one handle, which is used both when moving the tool and when depressing the impact device. In addition, the advantage is achieved that when the tool is lifted to move the force of gravity, it contributes to bringing the impact device back to its upper position relative to the guide part. Therefore, no return spring is needed for the shock device.

A magazine according to claims 3 to 5 is particularly simple. In such a magazine, the feed of holders is effected by means of gravity. In this case, the vibrations when moving the tool and during the indentation process result in safe feed-through. Such a magazine, which works with gravity, may just as well be designed as a tube in which the holders are arranged. However, it is particularly advantageous to design the magazine as a rod, along the outside of which the holders slide, since on such a magazine one can immediately see any disturbances in the feed. An abutment at the upper end of the magazine according to claim 5 prevents loss of the holder when the tool is not in its working position. Such a stop can be fixedly arranged, since the holders in U-shape can mostly be pressed from the side. The arrangement of longitudinal grooves according to claim 4 enables work with different length holders, without any adjustment of the device being required. Short holders are required when they are to be anchored at the surface or near the surface of the heat-insulating plates on which the heating pipes are placed.

An embodiment of the guide recess according to claim 6 facilitates further movement of the device from attachment point to attachment point. If the radius of curvature of the guide surfaces is selected in the manner specified in the requirement, contribute: the tool to ensure the installation regulations regarding the minimum possible radius of curvature for the bends of the heating pipe.

A height of the structure according to claim 7 is advantageous. With m such a height, on the one hand it becomes possible with a comfortable body position and on the other hand the floor can be kept under surveillance with the prescribed intensity. can have a compact construction with a distance between the magazine and the impact device according to claim 8. In an arrangement of the elements according to claim 11, the tool as a whole is relatively small and can then be built with a low weight to a corresponding extent. 453 895 The handle arrangement according to claim 7 in parallel with the heating tube is particularly suitable for single-handed operation. The contractor then moves forward in the laying direction of the pipe and holds the tool in one hand. Through the mentioned orientation of the handle, the correct alignment of the tool in relation to the heating pipe is obtained without coercion.

A ball engaging device according to claim 9 is a simple and safe working means for securing the holders against falling out at the ejection opening.

A constructive design according to claims 3 and 10 of the magazine rod and the shock device enables low weight and cheap manufacture, respectively.

Claims 12 to 17 define features for holders intended for use with the device according to claims 1 to 11. In general, the holders consist of injection-molded plastic, eg polyamide.

The lugs specified in claim 12 facilitate the pressing into the floor tiles in a direction parallel to the longitudinal direction of the legs, since the pressure over the lugs can be exerted approximately in the direction of the legs. Inserting the holders at right angles to the plane of the plates is important for secure attachment. The wedge shape of the holders according to claim 13 has the advantage that they abut against each other over surfaces at the curved part of the magazine rod, thereby ensuring that the holders align radially with respect to the curvature, thereby preventing the holders from tilting on the stomach rod. The sliding forward is also improved by a curvature of the holder at the interior of its rounded part according to claim 14, since edging is also thereby prevented. The design of a holder according to claim 15 allows, in a particularly advantageous manner, a plurality of holders together to form a charging belt, as stated in claims 16 and 17. Namely, in an embodiment of the holder according to claim 15, the connecting area has a cross section in right angle to the loading belt no curvature, so that the resistance to bending becomes small and thus the charging belt can easily adapt to the curvature of the magazine pliers. Both an adhesive strip and dimensional connecting life can be broken through when a holder is pushed in, so that it is not necessary to remove the connecting means after loading the magazine.

The main components of the device are a guide part 1, a shock device 2 movable relative to the control part and a magazine 3 fixedly arranged relative to the control part. The construction and interaction between these parts will be described in detail in the following.

The control part 1 has two mirror-facing building units 1a and 1b, which are screwed together. These two units complement each other to form a body, on which there is a guide recess 4 and an ejection opening 5. The ejection opening 5 is a channel with a rectangular cross-section, which extends over the entire height of the guide part 1. In this channel, the lower part of the shock device 2. The channel 5 is passed through by a pin 6, which serves as a stop for the movement beam of the shock device 2. A large breakthrough opening 7, 1 opens into the channel 5 (ejection opening), which also opens the lower end of the magazine set 3. The front end 8 of the magazine lies approximately in the same plane as the wall 5a of the channel 5, which is on the left in Fig. 1. The magazine is held to the guide part 1 by a holding shoulder 9 on the magazine is sandwiched between the guide part 1e 1e and 1b. The alignment is achieved by 8:11: 1o and 11. A pipe binding screw 12 passes through the part 1b ooh the fastening shoulder 9 and is screwed into the opposite part 1a. slightly opposite the end surface of the magazine 3, a knob engagement latch 13 designated as a whole is arranged. This has a body 14 with an external thread, which can be screwed into a threaded hole 15 in the component 1a of the guide part 1. Inside the body 14 is a helical compression spring 16, which acts on a ball 17. The ball 17 can be moved to the right by overcoming the force of the spring 16.

In the advanced position, as shown in Fig. 4, the ball projects over the wall Sb in the channel 5. In the situation in Fig. 1, the ball is retryed. 453 895 5 The guide recess 4 has convexly curved guide walls 18a and tabs.

The radius of curvature r is equal to the minimum radius of curvature of the heating pipes to be laid, ie eg 150 mm. The narrowest point of the guide recess is located where the guide recess opens into the channel s a nar a: the distance nellen the walls 1se een 1st accident- “like neaälh- heating pipe of the outer rim R. . the walls 19a a 191 »ner no one-phenomenon. The impact device 2 is made of an aluminum tube, which has a round outlet cross section. In the upper part 2a the pipe has its original cross-section, while its lower part is flattened and there has a cross-section, which can be seen in the view from below in Fig. 3. The part 2d fits in the channel 5 and is guided around it. In the part 2b there is a slot 20, through which the pin 6 passes. The lower end 20a of the slot 20 determines the highest possible position of the impactor relative to the guide member 1 and the upper end 20b the deepest possible position of the impactor, as shown in Fig. 1.

At the lower end of the impactor there are chamfers 21a and 21b.

At the upper end of the impact device there is a non-cylindrical handle 22, the longitudinal part 22a of which is parallel to the direction of movement of the device. This further movement takes place mainly along the dotted line 23 in Fig. 3. The handle is designed asymmetrically in relation to the impact device 2. Its longer part is directed towards the magazine 3, the height of which is so chosen that it is between the handle 22 and the upper end of the magazine 3, there is still a sufficiently large free space 24 for the handle to be gripped comfortably.

The magazine 3 is in principle a rod with an upper, straight part 3a and a lower, arcuately curved part 3b. The cross section of the magazine is drawn in the shelf part. as can be seen, a surface reinforcement down a mass portion 25 and two abutment side surfaces 26a and 26b. In between there are gutters 27a and 27b, which aim to save weight. The shape of the magazine bar is designed with simultaneous weight saving so that the holders H are guided well, namely on the rounding 25 and the guide surfaces 26a and 26b. b at the upper end of the magazine there is a bead-started projection 28, which projects over the inner contour of the holders H, so that the holders cannot slide over the end of the magazine, for example at a horizontal device.

The header device performs the work that follows. When filling the magazine 3, the holders on the magazine rod 3 are pushed from the side. In this case, the holders expand slightly. When the position is extended, the barbs 30 on the holders project over the end surface 31 of the magazine and are then held securely. In order to enable fast charging, the holders can be connected to each other with an adhesive strip after alignment, so that rows of holders can be pressed on at the same time. After application, the adhesive strip can be removed. he could also make longer bands of holders, the individual holders being connected to each other over life, which is broken off when the holders are pushed downwards. 1 When the impactor is in the raised position, the main holder H slides into the channel 5 (see Fig. 4), but cannot fall downwards because the ball 17, which engages in the rounding 29 of the holder, prevents this.

When the shock device is in its lower position, the front holder can only slide to the side surface of the shock device. When the device was used, it was grasped by the handle 22 and lifted. In this case, the impact device is pulled out of the guide part 1, so that the control part 1 slides downwards relative to the impact device due to its weight. In this case, the shock connection at each time reaches the position according to Fig. 4, so that a holder H enters the ejection opening 5. In the guide part 1 is placed over a heating pipe, which is to be fixed, after which the heating pipe R is located inside the guide recess. When the device is placed on the desired fixing point, the shock device 2 is pushed down strongly. The lower end of the shock device then abuts against the edges 32 and 33 of the holder (see Fig. 2), so that the holders cannot tilt sideways. When the holder is depressed, its side surface pushes in the ball 17 and moves past it. The legs of the holder are now pushed into the insulating plate P, which forms the base for the heating tube R. In this case, the barbs 30 slide into the area under an insert E embedded in the plate P. This prevents the holders from being pulled out, because the barbs 30 become suspended in the insert. E.

After a holder is pushed in, the device is moved to the next fix, whereby the device is lifted in the handle 22. Due to the specified dimensioning of the radius of curvature r, the device is also an aid against undeniably strong bends of the heating tube. At each wire tube surface area, the impact frame # 111 has an upper leg (rig 4), after which an additional holder slides into its ejection position due to gravity.

Suitable dimensions are for the distance a between the impact devices 2 axis 2c and the magazine rod 3 axis Be 100 mm and for the height h from the lower abutment surfaces 55a and 35b of the guide part 1 to the handle 22 upper side_453 895 7 _ 500 to 800 mm, preferably 700 mm. As the view from below according to Fig. 3 in particular shows, the device is built very narrow and is suitable as a result of this narrow construction and the special arrangement of the handle 22 for one-handed operation, in which the fitter walks along the pipe next to it and for the device with one hand along the tube. Due to the total arrangement, the position of the center of gravity is such that the device, even when grasped by the handle, hangs approximately vertically. The small width of the device also allows the heating pipes to be laid tightly. At the size shown, the pipe distance can be selected down to 40 mm.

In the device according to Fig. 5, the magazine rod 3 'has such a cross section that holders H and H' of different sizes can be used. Large holders H engage the magazine bar 3 'in the manner already described in connection with Fig. 1. Smaller holders H' engage with the ends 36a of their legs 36 into grooves 37 and 38, which are arranged on the magazine bar 3 'for this annal. in ssiiernn H- according to rig 6 een 7 differs from the holders H described in the journey in that in the area of the web part 39, which connects the legs 40 and 41 to each other, there are inclined surfaces 42 and 43, which converge upwards, so that a total wedge shape occurs, as Fig. 7 clearly shows. The bevel angle <* - is chosen so that the surfaces 42 and 43 of adjacent holders on the curved part 3b of the magazine rod 3 abut each other. This is shown in Fig. 10. He thereby prevents the holders from abutting each other only pointwise in the curved part 3b and thus that the holders stand on the edge of the magazine bar.

These adjust substantially radially with respect to the curvature due to the take-off surfaces 42 and 43.

A further difference in relation to the holder H lies in the fact that the inside 43a of the waist part 43 is convezically curved. The radius of curvature R corresponds to the radius of curvature of the inside of the curvature 3b of the magazine bar 3. The rounded inner surfaces 43a also provide good control of the holders H "in the curved area of the magazine bar 3. 'saiieren s fl- according to rig e een 9 down a further improvement, namely an upper flange 44, which is oriented at right angles to the symmetry plane 45, which extends between the legs 40 and 41. On the flat surface 44 several holders can be connected to each other to a charging band, for this purpose the holders are placed next to each other and connected by means of an adhesive strip, which is adhered to the surface 44. Such a charging band can be slid onto the magazine bar 3, 3 'across its longitudinal direction, the holders being pushed out slightly from each other until their barbs 36 and 36a, respectively, have come into position.

Claims (17)

453 895 the charging belt is easily bent, so that the adaptation to the curvature 3b becomes possible without problems. If the flattening 44 did not exist, but the holder had a shape of the type shown in Figs. 6 and 7, for example, a connecting strip would be arched, which would result in a considerable stiffening. The naiiarna according to rig 6 to 9 nar years 32 and 33, aan are arranged on shoulders 46 and 47 and which constitute a good point of attack when pressing the holder. By applying pressure in places that are at a great distance from each other, the holders are also prevented from tilting with certainty.
