Description

Field of the Invention

The invention relates generally to the field of radiators. In particular, the invention relates to an auxiliary element to enable the axial mounting of a thermostatic head on the control valve of a radiator.

State of the art

A radiator of known type comprises a heating line system. The heating line system can comprise, for example, heating pipes and / or heating plates. The heating line system is supplied with hot heating fluid (usually water) via an inlet, which circulates through the heating line system and is drained off via an outlet. The heating effect of the radiator depends on the volume flow of the heating fluid flowing through the heating line system. The more heating fluid flows through the heating pipe system per unit of time, the more the entire system heats up. The heat transfer to the ambient air takes place through heat radiation on the outer casing of the radiator. In addition, ambient air flowing through the radiator heats up by convection and is distributed at the top of the radiator, escaping into the surroundings, which is thereby heated.

To regulate the heating effect of the radiator, the heating line system includes a control valve on the inlet side. The control valve regulates the volume flow of the heating fluid through the heating line system. The control valve is in turn actuated via a thermostatic head, which is axially plugged onto the control valve and fastened to it by means of an assembly device (e.g. a nut). The mounting device is rotated using a suitable tool (e.g. a pipe wrench) around the axis of rotation of the thermostatic head and thus screwed onto a connection area (with an external thread) of the control valve. To assemble the thermostatic head, the assembly device must be freely accessible in order to transmit torque from a radial direction to the assembly device of the thermostatic head (e.g. using a pipe wrench).

The prior art includes radiators whose outer cladding is formed in one piece and surrounds the heating line system with a curve (on the side). In the 1a to 1c is a vertical radiator 10th shown according to the prior art. The vertical radiator 10th includes a heating pipe system (in the 1a to 1c not shown). The vertical radiator 10th also includes an outer panel 12 that the heating pipe system of the vertical radiator 10th encloses at the front and side. The outer cladding 12 points to the lateral boundaries of the vertical radiator 10th a semicircular curve on the left and right 122 on. The vertical radiator on the back 10th Fasteners (in the 1a to 1c not shown) with those of the vertical radiator 10th can be attached to the wall of a room.

The vertical radiator has on its underside 10th an inlet and an outlet that allow circulation of heating fluid through the heating pipe system. In the figures, the inlet and the outlet are together as an assembly 18th featured. There is a control valve in the immediate vicinity of the inlet 14 arranged. On the control valve 14 is a thermostatic head 16 appropriate. The thermostatic head 16 includes on one of the control valve 14 facing first side a mounting device 165 , by means of which the thermostatic head 16 with the help of a suitable tool on the control valve 14 can be screwed.

An exemplary thermostatic head 16 is in the 2a and 2 B shown. The thermostatic head 16 is cylindrical and has an axis of rotation 162 on. Equivalent thermostatic heads can have polygonal or oval shapes, for example. The thermostatic head 16 has a maximum outside diameter D _Tmax on. The thermostatic head points in the axial direction 16 also a first end 164 and a second end 166 on. At its first end 164 includes the thermostatic head 16 an assembly facility 165 used to connect the thermostatic head 16 on the control valve 14 is trained. The first end is accordingly 164 in one on the control valve 14 assembled state that the control valve 14 facing end of the thermostatic head 16 . The assembly facility 165 can preferably be of hollow cylindrical shape and have an internal thread, which is connected to a corresponding external thread of a connection area of the control valve 14 can be screwed around the thermostatic head 16 firmly on the control valve 14 to assemble. For example, the assembly device 165 of the thermostatic head 16 one at the first end 162 of the thermostatic head 16 rotatable around the axis of rotation 162 mounted connection sleeve or nut (not shown in the figures).

The second end 166 of the thermostatic head 16 is in one on the control valve 14 assembled state of the thermostatic head 16 the the control valve 14 opposite end of the thermostatic head 16 . By rotating the second end 166 of the thermostatic head 16 a desired heating temperature can be set.

By the arrangement of the control valve 14 and the thermostatic head 16 at the bottom of the vertical radiator 10th becomes an operation of the thermostatic head 16 for temperature control is more difficult, since the user has to bend down every time it is operated. In contrast, an attachment of the thermostatic head would be 16 on the side of the vertical radiator 10th and advantageous in a height that can be easily reached by the user. With the known means, however, is an assembly of the thermostatic head 16 on the side of the vertical radiator 10th not possible because of the curves 122 the outer cladding 12 about the assembly facility 165 of the thermostatic head 16 protrude and so the assembly facility 165 cover up. Assembly from the radial direction (ie perpendicular to the axis of rotation 162 ) is therefore excluded.

In order to increase the design freedom of radiators, there is a need to enable the mounting of conventional thermostatic heads from an axial direction. It is therefore an object of the present invention to provide a possibility for the axial mounting of conventional thermostatic heads.

Brief outline of the invention

To achieve the object on which the invention is based, an auxiliary element is provided to enable axial mounting of a thermostatic head on a control valve of a radiator. The auxiliary element comprises a base body which can be fastened in a rotationally fixed manner to an assembly device of the thermostatic head. The base body is designed such that it projects at least partially in the radial direction beyond the thermostatic head.

The terms "axial" and "radial" should be understood to refer to an axis of rotation of the thermostatic head. When mounted on the control valve, the axis of rotation of the thermostatic head is identical to an axis of rotation of the connection area of the control valve.

The mounting device of the thermostatic head can preferably be arranged at a first end of the thermostatic head. When the thermostatic head is mounted on the control valve, the first end of the thermostatic head can be the end of the thermostatic head facing the control valve.

The control valve can preferably have a connection area with a thread (e.g. an external thread). The mounting device of the thermostatic head can in turn have a thread which corresponds to the thread of the control valve and is designed for mounting the thermostatic head on the control valve.

The phrase "non-rotatably attachable" is to be understood such that the attachment of the auxiliary element to the assembly device is able to withstand at least one torque which must be applied to the control valve for assembling the thermostatic head.

The base body of the auxiliary element can comprise a torque receiving device. The torque receiving device can be designed for a rotationally fixed coupling of an assembly tool acting from the axial direction to the torque receiving device of the base body.

In other words, when the auxiliary element is attached to the thermostatic head, the recess can be at a distance from the axis of rotation of the thermostatic head that is greater than half the maximum diameter D _Tmax (ie the maximum radius) of the thermostatic head.

The base body can have an inner contour which essentially corresponds to an outer contour of the mounting device of the thermostatic head. The correspondence between the inner contour of the base body and the outer contour of the mounting device of the thermostatic head can serve to increase the torsional strength of the connection between the base body and the mounting device. For example, the rotationally fixed connection can be achieved by a force fit, material fit, or form fit between the base body and the assembly device.

In addition to the base body, the auxiliary element can comprise a tensioning element for non-rotatably tensioning the base body onto the mounting device of the thermostatic head. The clamping element can be a clamping screw, for example.

According to a variant, the base body can have a ring shape. Accordingly, the base body can have an inner diameter D _IH exhibit. The inside diameter D _IH the main body can essentially be one Correspond to the outside diameter of the mounting device of the thermostatic head. Furthermore, the base body can have an outer diameter D _AH have that is larger than a maximum outer diameter D _Tmax of the thermostatic head. The base body can also have a gap, which can be optionally enlarged and reduced by the tensioning element.

The base body can be made of a plastic.

To achieve the object on which the invention is based, an assembly tool for transmitting a torque to the auxiliary element described above is also provided. The assembly tool is hollow-cylindrical and has an inner diameter D _IM that is larger than the maximum outer diameter D _Tmax of the thermostatic head. In other words, the assembly tool is designed such that it can be put over the thermostatic head.

The assembly tool can further comprise a torque transmission device at an axial end of the assembly tool. According to a variant, the torque transmission device can comprise at least one highlight. The at least one highlighting can have a shape that essentially corresponds to the shape of a recess in a torque receiving device of the auxiliary element.

To achieve the object on which the invention is based, a radiator is also provided. The radiator comprises a heating line system with a control valve; an outer cladding that forms a front of the radiator and laterally encloses the heating pipe system; a thermostatic head for operating the control valve; and the auxiliary element described above, which is rotatably fixed between the control valve and the thermostatic head on a mounting device of the thermostatic head. The heating line system can comprise heating pipes and / or heating plates.

The control valve can be arranged on the side of the heating line system, the outer cladding in the area of the control valve having a recess through which the thermostatic head partially projects. In other words, part of the thermostatic head can be arranged inside and another part outside the outer casing. In particular, the first end of the thermostatic head with the mounting device and the auxiliary element attached to it can lie inside the outer cladding and the second end of the thermostatic head can be arranged outside the outer cladding. The second end of the thermostatic head is the free end of the thermostatic head facing away from the control valve.

The radiator can be a vertical radiator. The outer cladding of the vertical radiator can enclose the vertical radiator laterally in a semicircular shape. The outer cladding can preferably be formed in one piece.

The radiator can comprise fastening means on a rear side of the radiator opposite the front. The fastening means can be designed for fastening the radiator to a wall of a room to be heated (e.g. a living room).

To achieve the object on which the invention is based, a method for mounting a thermostatic head on a control valve of a radiator is also provided. The method comprises the following method steps: providing a radiator with a heating line system and a control valve, a thermostatic head with a mounting device, and the auxiliary element described above; Attaching the auxiliary element to the mounting device of the thermostatic head; and mounting the thermostatic head on the control valve of the radiator with the aid of the auxiliary element.

The step of fastening can include a rotationally fixed clamping of the auxiliary element on the mounting device of the thermostatic head. The non-rotatable clamping of the auxiliary element can take place in particular with the aid of a tensioning device of the auxiliary element.

The assembly step can include the following substeps: providing an assembly tool according to one of the variants described above; Coupling the assembly tool with the auxiliary element; and turning the assembly tool to screw the thermostatic head onto the control valve.

Detailed description

The 1a to 1c , and 2a and 2b have already been described in connection with the prior art. Please refer to the description there. The following is based on the 3a and 3b an auxiliary element according to the invention 15 to enable axial mounting of a conventional (commercially available) thermostatic head 16 according to the 2a and 2 B described in more detail.

The auxiliary element 15 comprises an annular base body 152 that has an inner diameter D _IH and an outside diameter D _AH having. The inside diameter D _IH of the basic body 152 can essentially have an outer diameter of a mounting device 165 at the first end 164 of the thermostatic head 16 correspond.

As shown in 3b points the main body 152 a smooth inner contour. According to an alternative variant, the base body can also have a corrugated inner contour, or an inner contour that essentially has an outer contour of the mounting device 165 at the first end 164 of the thermostatic head 16 corresponds. This can serve the torsional strength of the connection between the thermostatic head 16 and to increase the auxiliary element.

The basic body 152 of the auxiliary element 15 comprises a torque receiving device 154 . According to the in the 3a and 3b The variant shown includes the torque receiving device 154 two grooves 154a , 154b that in the main body 152 are formed at the end. The grooves 154a , 154b are designed in such a way that they allow the engagement of a suitable tool from the axial direction.

The auxiliary element 15 further comprises a tensioning element 156 . The clamping element 156 serves the auxiliary element 15 (or the base body 152 of the auxiliary element 15 ) rotatably on the assembly device 165 of the thermostatic head 16 to fix. This is in the main body 152 of the auxiliary element 15 A gap 153 formed which by the actuation of the clamping element 156 can be enlarged and reduced. According to the in the 3a and 3b variant shown is the clamping element 156 a screw. The basic body 152 points to both sides of the gap 153 corresponding recesses for receiving the screw. So the screw spans the gap 153 in the main body 152 . Will the screw 153 tightened, the gap narrows 153 and with it the inner diameter D _IH of the basic body 152 of the auxiliary element 15 . In this way it is possible to use the auxiliary element 15 to the assembly facility 165 at the first end 164 of the thermostatic head 16 to stretch.

In connection with the 4a to 4c An assembly is described below, the thermostatic head 16 according to the 2a and 2 B and an auxiliary element according to the invention 15 according to the 3a and 3b includes. The representations in the 4a to 4c show a state in which the auxiliary element 15 at the assembly facility 165 at the first end 164 of the thermostatic head 16 is attached. In particular from the representations of 4a and 4c shows that the main body 152 of the auxiliary element 15 in the radial direction (ie perpendicular to the axis of rotation 162 of the thermostatic head 16 ) protrudes beyond the thermostatic head. More specifically, the outside diameter D _AH of the basic body 152 of the auxiliary element 15 larger than the maximum diameter D _Tmax of the thermostatic head 16 .

In 4c is a view of the assembly perpendicular to the axis of rotation 162 of the thermostatic head 16 shown. The grooves 154a , 154b the front in the base body 152 of the auxiliary element 15 are located radially outside the thermostatic head 16 or protrude in the radial direction over the circumference of the thermostatic head 16 out. This means that an appropriate assembly tool (see e.g. 5 ) are placed over the thermostatic head and into the grooves from the axial direction 154a , 154b engage a torque on the auxiliary element 15 transferred to.

The following is in connection with the 5a and 5b an assembly tool 20th for transferring a torque to the auxiliary element 15 according to the 3a and 3b , and 4a to 4c. The assembly tool 20th is hollow cylindrical and has an inner diameter D _IM and an outside diameter D _AM on. The inside diameter D _IM is larger than the maximum outside diameter D _Tmax of the thermostatic head 16 (please refer 2a , 4a and 4a) . So the assembly tool 20th via the thermostatic head 16 be put on the auxiliary element by a torque 15 transferred to.

The assembly tool 20th has an axial end 22 on. At the axial end 22 is a torque transmission device 24th educated. The torque transmission device 24th comprises two highlights according to the variant shown 24a , 24b . These are dimensioned such that them in the recesses 154a , 154b in the basic body 152 of the auxiliary element 15 can intervene precisely. A non-rotatable connection between the assembly tool 20th and the auxiliary element 15 can thus by the engagement of the grooves 24a , 24b in the recesses 154a , 154b getting produced. In this way, the transmission of a torque from the assembly tool 20th via the auxiliary element 15 to the assembly facility 165 of the thermostatic head 16 enables.

In the 6a to 6d is a radiator according to the invention 30th shown. Elements of the radiator 30th that those in the 1a to 1c , 2a and 2 B , 3a and 3b , such as 4a to 4c are in the 6a to 6d provided with the same reference numerals. A detailed description of the functional and structural features of these elements is therefore omitted below and reference is made to the description of the corresponding figures. In the radiator shown 30th it is a vertical radiator. The radiator 30th comprises a heating line system (not shown) with a control valve 14 (see. 6d ). The radiator also includes 30th an outer cladding 32 . The outer cladding 32 forms a front of the radiator 30th and has rounded sides 322 on so that they have the heating pipe system on the sides of the radiator 30th encloses. The outer cladding 32 of the radiator 30th can be formed in one piece. That means that the outer cladding 32 according to a variant between the flat front and the rounded side flanks 322 has no seam or the like.

The radiator 30th includes a thermostatic head 16 to operate the control valve 14 and an auxiliary element 15 that between the control valve 14 and the thermostatic head 16 at the assembly facility 165 of the thermostatic head 16 is rotatably attached.

Like the vertical radiator 10th according to the 1a to 1c , shows the radiator 30th an inlet and an outlet on its underside (jointly identified by the reference symbol “ 18th ") on.

In contrast to the vertical radiator 10th , is with the radiator 30th the control valve 14 on the side of the radiator 30th arranged. At the level of the control valve 14 shows the outer lining 32 a recess 324 on. As shown in the 6a and 6b is the recess 324 circular. Alternatively, the recess 324 for example, have a polygonal or oval shape. The recess 324 has a diameter (not shown) that is larger than the outer diameter D _AH of the auxiliary element 15 . This is the only way the thermostatic head can 16 with the auxiliary element 15 through the recess 324 the outer cladding 32 inserted through and on the control valve 14 of the radiator 30th to be assembled.

When installed, the thermostat head protrudes 16 partly through the outer cladding 32 through so that the first end 164 of the thermostatic head 16 inside the outer panel 32 and the second end 166 of the thermostatic head 16 outside the outer cladding 32 is arranged. The auxiliary element is also corresponding 15 inside the outer panel 32 arranged. From the representation in 6d it can be seen that an assembly of the thermostatic head 16 from a radial direction would not be possible because the assembly device 165 of the thermostatic head 16 on which the auxiliary element 15 is attached by the outer panel 32 is covered.

In connection with 7 A method according to the invention for the axial mounting of a thermostatic head on the control valve of a radiator will now be described.

In a first step S72 the method comprises providing a radiator 30th with a heating line system and a control valve 14 , and a thermostatic head 16 and an auxiliary element 15 .

A second step S74 the method includes attaching the auxiliary element 15 at the assembly facility 165 of the thermostatic head 16 . The attachment of the auxiliary element 15 at the assembly facility 165 of the thermostatic head 16 can non-rotatably clamp the auxiliary element 15 to the assembly facility 165 include. The basic body 152 of the auxiliary element 15 can first do this on the assembly device 165 at the first end 164 of the thermostatic head 16 be put over. Then a clamping element (e.g. a screw 156 ) the basic body 152 of the auxiliary element 15 non-rotatable on the assembly device 165 be clamped.

In a third step S76 the method involves mounting the thermostatic head 16 on the control valve 14 of the radiator 30th with the help of the auxiliary element 15 . For this the thermostatic head 16 initially together with the auxiliary element attached to it 15 through the recess 324 in the outer panel 32 of the radiator 30th inserted so that the assembly facility 165 of the thermostatic head 16 with the connection area of the control valve 14 comes into engagement. Then an assembly tool 20th provided and with the auxiliary element 15 engaged around a rotationally fixed connection between the assembly tool 20th and the auxiliary element 15 to manufacture. The assembly tool 20th from the axial direction via the thermostatic head 16 put up. If in this way a non-rotatable connection between the assembly tool 20th and the auxiliary element 15 is produced, the assembly tool 20th with a torque applied to the auxiliary element 15 and on to the assembly facility 165 of the thermostatic head 16 is transmitted. In this way the thermostatic head 16 on the control valve 14 screwed tight. The torque required for this can be applied manually by a technician, for example.

The means and methods described here enable an axial mounting of a thermostatic head on the control valve of a radiator. This can meet the need for more freedom in the design of radiator geometries. In the case of a vertical radiator with rounded sides, lateral mounting of the thermostatic head can be made possible at a comfortable height for the user.
