Description

- Device for adapting a gutter holder to the inclination of the carrier receiving it

The invention relates to a device according to the preamble of claim 1.

To fasten gutters, hook-shaped, prefabricated brackets are used, the free legs of which adapt to the inclination of the girder, e.g. the roof or any other cover. This requires a bending process through which the free Leg of the holder receives the inclination of the carrier, during which, depending on the cross-sectional shape of the gutter semicircular or square hook of the holder in its normal i

j

Position remains in which an approximately horizontal recording

the gutter is guaranteed. As a carrier you can all conceivable supporting elements of roofs or coverings come into question, e.g. rafters, roof surface elements or the like .. In cases where gutters are also on flat

20th

roofs, terraces or balcony platforms are laid masonry or concrete layers can also form carriers for the holder.

There is already a bending device to carry out the bending process has been proposed with a pivotable bending lever, which enables the free leg of the holder to be bent around a support. The amount of deflection is thereby Appreciated in two ways by the person making the adjustments to the keepers. The first estimate concerns the inclination of the beam, which varies from roof to roof. The second estimate concerns the degree of deflection in the bending device. From this it is already clear that it is very difficult to find a holder

to adapt to the inclination of the carrier receiving him. 35

Measuring arm 5, which is to be aligned vertically for the measuring process 1st, the measuring arms 3 »5 are pivotably connected to one another in a joint 6, so that an optional angle w with a size of about 10 to s 120 ° between the Measuring arms 3, 5 is adjustable. On the first measuring arm 3 is a scale 7 curved around the joint 6 in the shape of an arc of a circle arranged on a semicircular disc 8, which is part of a vertical web 9 of the first measuring arm 3.

The second measuring arm 5 is designed with two legs, and

it engages over the disc 8 in the form of a fork. The bolt of the joint 6 extends through both legs 11, 12 of the second

Messärtns 5, whereby on the in F-i g. 1 visible side

a knurled nut 13 can be screwed onto the Gele.ikbol zen is, with which the stiffness of the joint 6 can be easily adjusted by hand. The one at the back of the measuring device 1 extending legs 12 of the second measuring arm 5 is used as a receiving device 14 for a still to be described holder 15 formed for the gutter, not shown.

The second measuring arm 5 is formed by a rail 16 of U-shaped cross section, the web 17 of the rail

16 arranged parallel to the pivot plane E (Fig. 2)!

i.e., the rail 16 is open to the rear of the meter 1 (Fig. 3). The arrangement, i.e. the attachment j the rail 16 on the bolt of the joint 6 is made in such a way that the one contact surface 18 to be described below

₃ q forming the inside of the leg 19 of the rail 16, which is closer to the carrier 4, lies approximately in the hinge axis 21. The inside of the web 17 of the rail 16 forms a second contact surface, denoted by 22 in FIG. 2, of the receiving device 14 for the holder

_

The legs 11, 12 of the second measuring arm 5 overlap §

«4

the disc 8 with mutual play in order to allow easy movement of the disc 8 between the legs 11 _s 12. In addition, this ensures that the Vörderseiti ge leg 11 does not rub on the scale 7, which is preferably glued to the disk 8. Die Vörderseiti In the area of the joint axis 21, spacers are arranged between the legs 11, 12 so that when the legs 11, 12 are pressed together by means of the knurled nut 13, friction surfaces act against one another only in the area of the joint. The front leg 11 is screwed to a web 24 extending from the rear leg 11, that is to say from the rail 16, by means of screws 23, which are indicated in the drawing.

The front leg 11 forms with a chamfered Edge 25, a display element 26 for the scale 7. The edge 25 extends radially to the joint 6.

To align the second during the measuring process To facilitate measuring arm 5 in its vertical position, a spirit level 27 is provided on the second measuring arm 5, in the present embodiment on the front Leg 11 is arranged and the air bubble is denoted by 28. After aligning the second

O 25 ^{measuring arm} ^ the angle w enclosed by the vertical and the upper side of the carrier 4 is measured. This angle w represents a linearly dependent variable of the actual roof inclination which results between a horizontal line and the upper side of the girder 4.

30th

To ensure that when there is heavy rainwater

the water overfilling the gutter, not shown, over its outer edge and not over its inner edge is running, in many cases the aim is to keep the gutter

__ to be arranged so that their inner edge is higher than 35

6th
j its outer edge. This requirement is in practice

accounted for by the fact that the angle w on the holder j 1 * »is slightly larger than required with the help of an additional angle

borrowed is carried out.

The inventive design enables a

exact measurement not only of the angle w between the vertical and the top of the carrier 4, but also of an additional angle described above. This is possible _n that a water balance Z7 bearing supporting part 29 can be locked parallel to or in the pivoting plane E about a hinge pin 31 pivotally and in the respective pivot position by a Feststel1glied 32nd The locking member is preferably a knurled nut, which can be easily loosened or tightened by hand. If the support part 29 is pivoted slightly counterclockwise with respect to the second measuring arm 5, then, after "vertical" alignment with the spirit level 27, the second measuring arm 5 is in a position in which it is pivoted clockwise from the vertical by the desired additional angle. The desired additional angle can thus be optionally preset.

With the measuring device 1, not only that of the inclination can be measured

O oc of the carrier 4 measure corresponding angle w, but 25th

it also enables the holder 15 to be marked the point at which its free leg 33 is to be bent. This point is designated by 34 in FIG. 1 and lies in the extension of the top of the carrier

4. The marking of the point 34 on the free leg 30

33 is easily possible with a colored pencil or a scriber by using the marking tool on the Underside 35 of the first measuring arm 3 is moved along. To enable precise identification,

is the rear lower edge 36 in the plane of 35

% second contact surface 22, on which the holder 15 rests with its narrow side. Therefore, the holder 15 or its free leg 33 is also located directly on the rear lower edge 36, whereby an error-free

5 marking is made possible.

The automatic abutment of the holder 15 with its broad side on the contact surface 18 of the receiving device 14 or the second measuring arm 5 is made possible by a _{spring 30 designed as a leaf spring 10} , which is attached to the leg of the rail 16 designated by 39 at 41 and is bent - or loops in the free 1 ^ v space of the rail 16 extends.

I The arrangement of the spring designed as a leaf spring

I. 38 has another advantage. This exists

I mean that such when they come with an arch-shaped

1 section rests on the free leg 33 of the holder 15,

I when inserting the free leg 33 of the holder

I will. In principle, a coil spring would also be needed

cash, but such would have to be provided with a runner 35

in order to be able to give way when inserting the free leg 33. The aforementioned advantage of a leaf spring is also clear with regard to a sheet metal strip 43 attached to the inside of the free leg 33, which protrudes slightly from the free leg 33 and in the presence of a leaf spring when Insertion into the receiving device 14 is unproblematic is pushed under the leaf spring.

At the front of the through a sheet metal strip of Approx. 3 to 4 mm thickness formed measuring arm 3 is with the bottom 35 finally an angle rail 44 attached. On the back of the first measuring arm 3 is, if this is formed from a sheet metal strip, a rail 45, the thickness d of which corresponds to the distance that the second contact surface 22 from the rear of the second measuring arm 5 has. The angle rail 44 and the rail 45 thus form a foot of the first measuring arm 3. The width B of this foot is not larger than the width B of the holder 15. This ensures that in those cases in which the free leg 33 of the holder 15 in the top of the carrier 4 is let in, e.g. if there is an eaves formwork, the first measuring arm 3 can be inserted into the recess of the recess. In this case it is It is also important that the length 1 of the first measuring arm 3 - measured from the joint 6 - is not greater than that Section of the free leg 33 lying on the carrier 4, since the existing recess does not otherwise fail

_ao would be sufficient to accommodate the first measuring arm 3.

The essential parts of the bending device 2 are a support leg

51, a bending lever 52 and a * i ^; part 53 for support

of the holder 15 during bending, where the support leg 51

are pivotally connected to each other.

The support leg 51 consists of a tube of square cross-section, on which the joint 54 facing End side cheeks 57 are welded. The bending lever 52 consists of a tube of round cross section, on whose the end facing the joint 54 a square tube 56 is attached and welded. Near the joint are the j directed transversely to the bending plane BE (Fig. 5)

Square tube walls are cut out so that side walls remain, of which the side walls 57 of the support leg 51 overlap the side cheeks 58 of the bending lever 52. The joint 54 is formed by a joint pin 59, which engages the side cheeks 57, 58 in a joint bore. In Fig. 5 are the levers 52 and the support leg 51 is shown stretched for the sake of clarity.

The side cheeks 57 of the support leg 51 are widened at their free ends to form circular disks, to which the side cheeks 57 adjoin tangentially or secantially. In the center of the designated 61 The hinge axis 62 of the hinge 54 is located in the form of annular disks.

A is located between the side walls 57, 58

in Fig. 5 with 63 designated free space into which the holder 15 is inserted for bending. The bending support 64 is formed by the hinge pin 59. In one

OQ distance from the hinge pin 59 extends parallel

to this an abutment bolt 65, which is on the inside the side carriage 57 is attached. Since the width of the side cheeks 58 of the bending lever 52 is much narrower are dimensioned * as the diameter of the circular

_ac , washers 61 is between the edges of the side walls

57, 58 Space enough to arrange the abutment bolt 65 available.

On the opposite of the abutment bolt 65 Side is a push pin 66 on the insides of the

5
Side cheeks 58 attached, which is also parallel

extends to the hinge pin 59. The bolts 69, 65 and 66 are preferably round bolts that can be welded to the side walls 57, 58.

IO

On the outside of one of the side walls, preferably

the left side cheek 57 of the support leg 51 with respect to the operating side 68 has a scale 69 attached, which cooperates with einam display element 71 that on

Flex lever 52 is attached. This scale is located at 69

in a nutshell.

Before adjusting the holder 15, first of all is the inclination of the carrier 4 to determine »for which purpose the first measuring arm 3 of the measuring device 1 is placed on the carrier 4 and the second measuring arm 5 is aligned vertically, the latter can be by eye or preferably with the help of Spirit level 27 take place, a small additional angle being taken into account in the manner already described liäTrfi, ΙϊϊΓΐ ZU ycWäiir ι el Sterr, uönj uST 1ΠΠβΓ £ i \ öfiu ueT

installed gutter is slightly higher than its outer edge. The degree of inclination of the wearer C. 4 is displayed on the scale 7 by the display element 26.

It is advantageous and this is made possible by the invention Measuring device 1 also makes it possible to determine the point at which during the inclination measurement on the carrier 4 the free leg 33 of the holder 15 is to be bent. This is the case with the embodiment according to the invention

20th

by receiving the holder 15 in the receiving device 14 made possible during the measurement of the inclination, because the position of the upper side of the carrier 4 with respect to of the holder 15 in the manner already described on

C free leg 33 can be identified. 25th

For bending, the free leg 33 with its outside designated 91 is down into the free space 63 of the support part 53 inserted in such a way that the free leg 33 between on the one hand the abutment bolt 65 and the pressure bolt 66 and on the other hand, the hinge pin 59 is located. It is important to ensure that the marked bending point 92 is is located on the support 64, which is formed by the hinge pin 59. The scale is in this position 69 to bring it into its basic position, but only that

is then required if the scale is 69 beforehand a thicker or thinner free leg 33 was set * Then the free leg 33 is pivoted down of the bending lever 52 to bend until the indicated by the display element 71 on the scale 69 The value corresponds to the value determined on the carrier 4.

It is advantageous to form the scales 7 and 69 by graduation. However, they are also arbitrary divisions possible, but there must be a certain relationship between the divisions on the scales.

Depending on the tolerances and conformity of the support 64 with the bending point 92 and due to the fact that the bending point 92 is not in the center of the Joint 54 is located (radius of the joint pin 59), it may be that the angle y actually obtained after bending differs from the angle um that the bending lever 52 has been pivoted for bending. This can be done by a correspondingly different Graduation on the 69 scale must be taken into account. In one embodiment, therefore, is the division on scale 69 compared to that on scale 7 by approx. 10% ^, i.e. 90 ° on scale 7 actually corresponds ^ - 25 about 81 ° on the 69 scale, although the divisions on the Scales 7, 69 are labeled with the same degree specifications (90 °).

In the case of gutters, it is necessary to have the length a of the section of the holder 15 denoted by 93 in FIG to be extended to the downpipe of the gutter in order to obtain a slope for the gutter. This circumstance is taken into account in the above-described method for adapting the holder 15 that the bending point 92 (Fig. 4) opposite the identification point 34 (Fig. 1, 2) shifted towards the free end of the free leg 33

14th

1 is so that the section a from holder 15 to holder 15 suffered a certain degree of increase.
