Abstract
Description
- The invention is related to a door for an electrical appliance cabinet, in particular a distribution cabinet, with at least one hinge, which is fixed releasably thereto and which has a base body with a hinge pin, said hinge pin engaging in a cutout provided for this purpose in the appliance cabinet in question and thus guiding the door pivotably, wherein the door is provided on at least one longitudinal side with a rebate, wherein the base body is inserted into said rebate, and wherein the rebate is angular, and wherein that limb of the rebate which points towards the inner side of the cabinet is provided with a first cutout.
- Electrical appliance cabinets are used for housing electrical components. Especially in the technical field of meter- and distributor cabinets, doors have to be set and oriented in the electrical appliance or distribution cabinets. The procedure of orienting the door in the cabinet is called adjusting the door, and it is done when the door is inserted to or set to the cabinet by adjusting the door hinge accordingly.
- A door for an electrical cabinet of this kind is disclosed in
EP 2 362 045 B1 - Concretely, operating the door hinge according to
EP 2 362 045 B1 - The object of the invention therefore is to develop a door for an electrical appliance cabinet with a door hinge, which can be adjusted without separate tools.
- The object of the invention is achieved by means of the features of
claim 1. - According to this claim the base body comprises a first fastening means, and the base body when inserted into the rebate is pivotably fixed on the door by means of a second fastening means passing through said first cutout and cooperating with the first fastening means to form a configuration which pivotably fixes the base body in the rebate, the first fastening means determining the pivot point of the door hinge, and wherein the base body comprises an adjusting means for enabling an adjustment of the base body with respect to the door, wherein said adjustment means, when the base body is inserted into said rebate, is supported at the door and is configured to be operated at the side of that limb of the rebate which points towards the inner side of the cabinet.
- According to the invention it has been found that the base body of the door hinge has to comprise a first fastening means, which permanently determines the pivot point of the door hinge within or on the door. The base body or a part of the base body may be turned or swiveled around this permanent pivot point relatively to the door. Turning or swiveling the base body or a part of the base body results in changing the position of a hinge pin protruding from the base body within or on the door. Due to the feature that the base body comprises an adjusting means for enabling an adjustment of the base body with respect to the door, wherein said adjustment means, when the base body is inserted into the rebate which is provided on the door, is supported at the door and is configured to be operated at the side of that limb of the rebate which points towards the inner side of the cabinet, the door easily can be oriented within the cabinet without using a screw driver. Due to the feature that the base body when inserted into the rebate is pivotably fixed on the door by means of a second fastening means passing through a first cutout in the door and cooperating with the first fastening means to form a configuration which pivotably fixes the base body in the rebate, the user has no need to operate the second fastening means, when he wants to adjust the door hinge within or on the door. He can use the adjustment means connected to the base body, which moves the base body relatively to the door. Through this, the base body can be moved without a separate tool. Due to the feature that the adjustment means is configured to be operated at the side of the limb of the rebate which points towards the inner side of the cabinet, it is avoided that by accident the adjustment means, once the door has been adjusted, can be dislocated by a person when the door is closed in the installed position of the cabinet. An additional protection against such an accidental dislocation of the adjustment means is the feature that the adjustment means is supported at the door, when the base body is inserted into the rebate which is provided on the door.
- Advantageously, the first fastening means comprises a second cutout in the base body, and the second fastening means comprises a screw, wherein the second cutout is configured to enable a releasable bolted fastening between the screw and the second cutout.
- Further advantageously, the first fastening means comprises a tubular projection made of a plastic material, and the second fastening means comprises a thread-forming metal screw.
- Further advantageously, the door has a round hole, through which a screw may protrude to the second fastening means. The base body may be screwed in place in a factory-provided manner using a screw.
- Further advantageously, the fastening means comprises a threaded hole in which a screw may be screwed. Through this, a hard mechanical connection between the base body and a door is possible. The screw does not have to be released to move the door hinge.
- Further advantageously, the adjusting means comprises a hand wheel as a moving means which is connected to a longitudinally extending threaded shaft in a torque proof manner, wherein the threaded shaft is received in at least one mating thread, which is connected to the base body in a torque proof manner, wherein turning the hand wheel with respect to the base body is enabling a lateral movement of the threaded shaft in its longitudinal direction with respect to the base body, guided by the at least one mating thread, said lateral movement of the threaded shaft enabling a movement of the base body within or on the door. The door hinge or the hinge pin may thus be moved relatively to the door only by turning the hand wheel. By moving the base body the hinge pin is moved or turned relatively to the door.
- Further advantageously the door has a third cutout comprising convex lateral edges to support the hand wheel when the base body is inserted into the rebate. The hand wheel may be supported on a lateral edge of the door while turning the hand wheel. This creates a counterforce which moves the base body relatively to the hand wheel and relatively to the door. The position of the hand wheel in the door remains fixed between lateral edges, wherein the hand wheel is rotatable.
- Advantageously, the hand wheel is composed of two parts which are configured in a way to complete a wheel shape when assembled, wherein a first part is fixedly connected to the threaded shaft, the first part having a flattened section in its circumference, and wherein a second part is configured to be connected to the first part and to complement the wheel-like shape when assembled to the flattened section of the first part. This has an advantage when inserting the base body into the rebate of the door. Upon inserting, initially the second part of the hand wheel is taken away, so due to the flattened section in the circumference of the hand wheel insertion of the base body into the rebate is possible. When the base body is in place inserted into the rebate, the flattened section lies in a position matching the third cutout. Now the second part of the hand wheel is connected to the flattened section, reaching through the third cutout, to complete the hand wheel. In this way, after completion of the hand wheel, a part of the hand wheel reaches out of the surface of the limb of the rebate that points towards the inner side of the cabinet, so it can be manipulated by an operator to adjust the door, without this outreaching part blocking the base body on insertion into the rebate.
- Further advantageously, the door has an elongated hole or an elongated cutout, and when the base body is inserted into the rebate, the hinge pin protrudes through the elongated hole or the elongated cutout within the door. The hinge pin thus can move in one direction or two directions in the elongated hole, until its movement is stopped by an edge of the elongated hole or cutout.
- Further advantageously, the door has an arched lateral outer edge. The hand wheel as a whole thus easily can pass the outer edge of the door, particularly the outer edge of the rebate of the door, when the door hinge is mounted into the rebate of the door. This enables inserting the base body into the rebate when the hand wheel is designed as one single piece. The hinge pin may already protrude through an elongated hole and the hand wheel may be moved into the third cutout having convex lateral edges.
- Advantageously, the hinge pin is stiffly fixed at the base body. This is an easy way of applying the hinge pin. It may be screwed to the base body or produced in an injection molding process together with the base body.
- Further advantageously, the hinge pin is guided in the base body in longitudinally displaceable fashion and the base body has retaining means enabling to hold the hinge pin in a position protruding through the elongated hole or the elongated cutout within the door. Through this, the hinge pin reversibly may be pressed in the direction of the base body to assemble the door hinge within a door, and when the door hinge has been assembled, the retaining means will make the pin again protrude through the elongated hole or the elongated cutout within the door.
- Further advantageously, the hinge pin is spring loaded. In an advantageous manner, the hinge pin is spring loaded by a flat spring or leaf spring. The spring creates a reset force. A flat spring or leaf spring is durable and long-lasting.
- Advantageously, if the hinge pin is not spring loaded, the base body has clamping means configured to interact with the hinge pin enabling it to be held in a position protruding through the elongated hole or the elongated cutout within the door. Here the design is simpler, avoiding the additional part of the spring. The hinge pin has then to be moved manually in its operating position protruding out of the elongated hole after insertion of the base body into the rebate of the door.
- Advantageously, the base body is made of a synthetic material or a plastic. A synthetic material or a plastic does not rust or oxidize.
- Further advantageously, the hand wheel is made of a synthetic material or a plastic. A synthetic material or a plastic does not rust or oxidized.

Thedoor 2 is provided on one longitudinal side with arebate 20, wherein thebase body 1 is inserted into saidrebate 20. Therebate 20 is angular, and thatlimb 21 of therebate 20 which points towards the inner side of the cabinet is provided with afirst cutout 10. -
Hinge pin 4 protrudes from thebase body 3. Thebase body 3 comprises a first fastening means 5. Thebase body 3 when inserted into therebate 20 is pivotably fixed on thedoor 2 by means of a second fastening means 7 passing through saidfirst cutout 10 and cooperating with the first fastening means 5 to form a configuration which pivotably fixes thebase body 3 in therebate 20. The first fastening means 5 determines thepivot point 6 of thedoor hinge 1. Thebase body 3 comprises an adjusting means for enabling an adjustment of thebase body 3 with respect to the door. The adjustment means, when thebase body 1 is inserted into therebate 20, is supported at thedoor 2 and is configured to be operated at the side of thatlimb 21 of therebate 20 which points towards the inner side of the cabinet. - As shown in
figures 2 and3 , the first fastening means 5 comprises asecond cutout 5a in thebase body 3. The second fastening means comprises ascrew 7, wherein thesecond cutout 5a is configured to enable a releasable bolted fastening between thescrew 7 and thesecond cutout 5a. - The first fastening means 5 comprises a tubular projection made of a plastic material, in which the
second cutout 5a is made, and the second fastening means comprises a thread-formingmetal screw 7, which, when screwed into thesecond cutout 5a, forms its own thread. - Alternatively, the first fastening means 5 may comprise a threaded hole in which the
screw 7 may be screwed. - The
hinge pin 4 is spring loaded. Thebase body 3 comprises ahand wheel 8, which may be operated to move thehinge pin 4 relatively to thedoor 2. -
Fig. 1 concretely shows an assembly, comprising thedoor hinge 1 and thedoor 2. Thebase body 3 is screwed in place in a factory-provided manner using thescrew 7. - The
hinge pin 4 protrudes through anelongated hole 9 within thedoor 2. Thedoor 2 has around hole 10, through which thescrew 7 protrudes to the first fastening means 5. Thedoor 2 has acutout 11 comprising two convex lateral edges 12 to support thehand wheel 8 protruding in part through thecutout 11. Thedoor 2 has an arched lateralouter edge 13. - The
base body 3 is made of a synthetic material. Thehand wheel 8 is made of a synthetic material. Thedoor 2 is made of iron sheet. - The
hinge pin 4 may be pressed into thedoor 2, if thedoor 2 is placed on a floor. If thedoor 2 is lifted from the floor and thehinge pin 4 is unloaded from the weight of thedoor 2, thehinge pin 4 returns to its position protruding from thedoor 2, because the force of theflat spring 14 is sufficient. -
Figs. 2 and3 show thedoor hinge 1 to be installed within or on thedoor 2 of an electrical cabinet, comprising abase body 3, from which ahinge pin 4 protrudes in two outer directions nearly perpendicular to each other. Thehinge pin 4 protrudes in one direction, which is shown by a dashed arrow, to be received in a hinge mounting. - The
hinge pin 4 is spring loaded and housed in thebase body 3. Thebase body 3 comprises thehand wheel 8, which may be operated to move thehinge pin 4 relatively to thedoor 2. Thehinge pin 4 is spring loaded by aflat spring 14. - The
base body 3 comprises thehand wheel 8, which may be turned relatively to thebase body 3 to move thebase body 3 within or on thedoor 2. Thehand wheel 8 is connected with a threadedshaft 15 in a torque proof manner, wherein the threadedshaft 15 is received in amating thread 16, which is connected with thebase body 3 in a torque proof manner. Thehand wheel 8 can be moved in two directions relatively to thebase body 3. - The
hinge pin 4 is arranged in thebase body 3, before thedoor hinge 1 is arranged in or on thedoor 2. -
Fig. 4 shows thedoor 2 ofFig. 1 . Thedoor 2 has the elongatedhole 9 within thedoor 2 on a top edge of the door. It is also possible to arrange thehole 9 and thedoor hinge 1 on a bottom edge of thedoor 2. - The
door 2 has therebate 20, with thelimb 21 of therebate 20 pointing towards the inner side of the cabinet. - The
door 2 also has theround hole 10, in thelimb 21 of therebate 20, through which thescrew 7 shall protrude. Thedoor 2 has thecutout 11 comprising the two convex lateral edges 12 to support and fix thehand wheel 8 between them, wherein thehand wheel 8 is rotatable being assembled in thedoor 2. Thedoor 2 has an arched lateralouter edge 13, which is made at the lower part of the free longitudinal edge of thelimb 21 ofrebate 20, and which offers place to let pass thehand wheel 8, when thedoor hinge 1 is mounted into thedoor 2. -
Figure 5 shows a second embodiment of a door hinge according to the invention. Here thehand wheel 8 is composed of two parts which are configured in a way to complete a wheel shape when assembled. For detail see alsofig. 6 . Afirst part 22 is fixedly connected to the threadedshaft 15, thefirst part 22 having a flattenedsection 24 in its circumference. Asecond part 23 is configured to be connected to thefirst part 22 and to complement the wheel-like shape when assembled to the flattenedsection 24 of thefirst part 22. For this purpose, thesecond part 23 has a shape generally like a segment of a circle, with two resiliently formedlegs bent surface 28 of the segment form. Each of thelegs like structure first part 22 is equipped with an opening on its flattenedsection 24, having recesses at its edges. When thesecond part 23 is assembled onto thefirst part 22 for completing the circular shape of thehand wheel 8, thelegs like structures second part 23 on thefirst part 22 to complete thehand wheel 8. - As can be seen in
figure 5 , there is no need for the arched lateral edge at the free longitudinal side of thelimb 21 ofrebate 20 for insertion of thebase body 3 into therebate 20. This makes production of thedoor 2 easier, as for creating such an arched lateral edge, special tooling is needed. In the embodiment offig. 5 , the edge is flat, requiring no such special tooling. Upon inserting thebase body 3, initially the second part of thehand wheel 8 is taken away, so due to the flattenedsection 24 in the circumference of thehand wheel 8, insertion of thebase body 3 into therebate 20 is possible. When thebase body 3 is in place inserted into therebate 20, the flattenedsection 24 lies in a position matching the third cutout. Now thesecond part 23 of thehand wheel 8 is connected to the flattened section, reaching through the third cutout, to complete thehand wheel 8. In this way, after completion of thehand wheel 8, a part of thehand wheel 8 reaches out of the surface of thelimb 21 of therebate 20 that points towards the inner side of the cabinet, so it can be manipulated by an operator to adjust thedoor 2, without this outreaching part blocking thebase body 3 on insertion into therebate 20. -
Figure 6 shows a third embodiment of a door hinge according to the invention. Here the base body has clamping means 25 configured to interact with thehinge pin 4 enabling it to be held in a position protruding through the elongated hole or the elongated cutout within thedoor 2. This design avoids an additional part such as a spring to keep thepin 4 in its position protruding out of theelongated hole 9. Thehinge pin 4 has then to be moved manually in its operating position protruding out of theelongated hole 9 after insertion of thebase body 3 into therebate 20 of thedoor 2. The clamping means is designed as two resilient arms with snapping noses at their free ends, forming in between them a round opening adapted in size to fit to the outer circumferential diameter of thehinge pin 4. When thehinge pin 4 is moved into its operating position, the position shown infigure 6 , it is held in a snap-fixed manner between the two resilient legs. -
Figure 7 shows a door hinge with a hand wheel as described in the context offigure 5 , the two-parted and assembled hand wheel, when inserted into therebate 20 ofdoor 2. -
Figure 8 shows a door hinge where thehinge pin 4 is stiffly fixed at thebase body 3. This is an easy way of applying thehinge pin 4. It may be screwed to thebase body 3 or produced in an injection molding process together with thebase body 3.Reference numbers 1 Door hinge 2 Door 3 Base body 4 Hinge pin 5 First fastening means 5a Second cutout in base body 6 Pivot point of 3 7 screw 8 Hand wheel 9 Elongated hole 10 First cutout, round hole 11 Third cutout 12 Convex lateral edges of 11 13 Lateral outer edge 14 Flat spring 15 Shaft 16 Mating thread 20 Rebate 21 Limb of rebate 22 First part of hand wheel 23 Second part of hand wheel 24 Flattened section of first part 25 Clamping means 26 Resilient leg 27 Resilient leg 28 Bent surface 29 Nose- like structure 30 Nose-like structure
