Definitions
- the invention relates to a frame in particular for receiving a filter element according to the type defined in more detail in the preamble of claim 1.
- connection arrangement and a tensioning frame for textile goods containing such an arrangement are known, in which several elongated components connected at an angle with recesses on the end faces for producing a frame and connecting pieces with legs for insertion into the recesses are provided are.
- the connecting pieces are produced by separating an appropriately dimensioned length from an extrusion body and can be inserted into the recesses.
- the extrusion body has hollow sectors which extend in the extrusion direction of the extrusion body.
- the end faces of the elongated components are inclined so that the elongated components are connected to one another at a right angle.
- the connecting pieces are L-shaped and have a reinforcing element in the corner section, the legs of which end in an inclined end face, which form an essentially right angle with the end faces and lie on one plane.
- connection between the elongated components and the connecting pieces is locked by a pin which is inserted through a wall of a hollow elongated component into a receiving device which corresponds to the passage of the elongated component.
- DE 36 12 511 A1 describes a rigid frame made of square metal profiles of a distribution cabinet, in which a device carrier which can be inserted and is fastened therein is to be arranged for attaching electrical devices.
- the rigid frame has vertical supports and horizontal bars and struts.
- the hollow existing supports, spars and struts of the frame are connected to each other by means of corner connectors which are provided with clamping arms which can be inserted into the supports, spars and struts.
- the clamping arms have at least one longitudinal slot into which a spreading element can be inserted or driven.
- GB 1 593 209 describes a frame which consists of four frame parts, each of which is provided with miter cuts at its ends and is connected to one another via corner connectors.
- the corner connectors have cutouts into which punched-out tabs protruding from the frame parts engage. This avoids an independent loosening of the connection between the corner connectors and the frame parts.
- a profile frame for receiving flat parts, in particular glass panes, the mitred frame profiles of which are held together at the frame corners by positively engaging connecting angles in their hollow frames, is known from DE 30 35 361 C2.
- depressions such as beads or tongues
- the recesses are open to enable the frame to be released or opened.
- a clamping element such as a wedge or a bolt, is provided on these corner connectors in order to form a firm connection between the frame parts and the corner connectors. The clamping elements are easily removed to open the frame.
- the invention is based on the object of providing a frame, in particular for accommodating a filter element, with frame parts and coupling elements for connecting two adjacent frame parts in each case, which is easy to assemble and whose manufacture can be carried out with only low demands on manufacturing tolerances.
- the latching device has at least one latching element formed in the region of the end sections of the frame parts and the coupling elements and a counter-latching element corresponding to the latching element, the latching element and / or the counter-latching element in a latched position of the latching device in a reversible manner
- Deformation clamping position is brought by the locking element and / or the counter-locking element. Due to the reversible deformation clamping position of the locking element and / or the counter-locking element, the clamping force acting in the joining direction of the coupling element and the frame part is generated, which ensures in particular a gap-free contact of the two adjacent frame parts on their abutting edges.
- the detent is reversibly releasable, so that when a filter element of an extractor hood is replaced, the frame can be easily removed and then reassembled.
- a cross-sectional profile of a frame part and a cross-sectional profile of a coupling element in the region of the end sections are matched to one another in such a way that the coupling elements and the frame parts can be at least partially inserted into one another for connection, so that a positive connection between the frame parts and the coupling elements can be produced and in particular when the coupling elements can be inserted into the frame parts, a uniform, smooth frame surface is achieved.
- the counter-locking element and the locking element are preferably designed in such a way that when a coupling element is installed with a frame part, a counter-locking element is pressed past a locking element by means of a joining force with deformation of the counter-locking element and / or the locking element, with a residual deformation of the locking element when the locking device is locked
- Counter locking element and / or the locking element for generating the clamping force due to the engagement of the locking element on the counter locking element remains.
- the connection between two adjacent frame parts is established only via one component, i. H. accomplished a coupling part without additional centering components, clamping means or fasteners, which results in a simple and quick assembly.
- the requirements for the manufacturing tolerances are low, since the degree of deformation of the latching element and / or the counter-latching element guarantees the full functionality of the latching device even within a wide range.
- Another preferred embodiment of the frame has a locking device for locking the latching device, wherein the engagement of the latching device cannot be released in the locked state.
- the coupling element has two legs, each arranged at an angle, preferably at a right angle, for receiving a frame part each, and the end section of each frame part has a miter angle matching the angle between the two legs to form a miter connection, whereby the clamping force acting in the joining direction permanently presses the assembled frame parts together.
- the coupling element is made from a plastic and the frame part from a metal, preferably from an aluminum or an aluminum alloy or a stainless steel. This combination of materials advantageously prevents corrosion, since only the same materials but without a voltage gradient collide, the coupling element made of plastic being neutral in this regard.
- the frame part has a U-shaped cross-sectional area for receiving a filter element, the filter element being designed as a woven or knitted fabric which is made of the same material as the frame part, thereby causing corrosion between the frame parts and the filter element is avoided.
- Figure 1 shows a highly schematic longitudinal section through a frame part of a frame, in which a coupling part is at least partially inserted.
- FIG. 2 shows a three-dimensional schematic illustration of the coupling part according to FIG. 1 in a single view
- FIG. 3 shows a plan view of a coupling part which is provided with a plurality of cutouts
- FIG. 5 shows a cross section of a frame part along the line V-V according to FIG. 1st
- Fig. 1 shows a longitudinal section through a frame part 1, which represents an at least approximately C-shaped hollow profile, in which a coupling element 2 is inserted.
- the coupling element 2 is formed from two legs 3, 4 arranged at right angles to one another, the leg 3 being formed into a not shown to form a Provided frame part, which is arranged adjacent to the frame part 1 in the same manner as the leg 4 of the coupling element 2 is inserted into the frame part 1.
- the coupling element 2 serves as a connecting element of two adjacent frame parts, a latching device 5 being provided between the coupling element 2 and the adjacent frame parts for latching the frame part 1 and the further frame part (not shown in more detail) with the coupling element 2 in the assembled state.
- the latching device 5 is designed in such a way that in the locked position of the coupling element 2 and the frame part 1, a clamping force acting in the joining direction of the coupling element 2 and the frame part 1 acts on the latter.
- the coupling element 2 is in each case formed on its legs 3, 4 or in the region of the end sections of the legs 3, 4 each with a latching element 6.
- the frame part 1 is provided with a counter-locking element 7 corresponding to the locking element 6, the locking element 6 being in the locked position of the locking device 5 in a reversible deformation clamping position due to the contact of the counter-locking element 7.
- the locking element 6 is designed as an arc spring which is arranged integrally on the coupling element 2.
- the counter-latching element 7 is pushed past the latching element 6 by means of a joining force with deformation of the latching element 6, wherein in the latched state of the latching device 5, a residual deformation of the latching element 6 for generating the clamping force due to the engagement of the latching element 6 remains on the counter-locking element 7.
- the reversible deformation clamping position of the locking element 6 generates the clamping force acting in the joining direction of the coupling element 2 and the frame part 1 in that the counter-locking element 7 deforms and prestresses the spring-elastic locking element 6.
- the counter-latching element 7 has a projection 8 with a bevel 9, the latching element 6 having an engagement section 10 which is deformed in the latched state shown and presses against the bevel 9 of the counter-latching element 7.
- the coupling element 2 according to FIG. 1 is shown in a schematic three-dimensional representation, with a locking device 11 for locking the locking device 5 being provided in the area of the locking elements 6, so that in the locked state of the locking device 5, the engagement of the locking device 5 does not occur is solvable.
- the locking device 11 has a locking part 12 which, for locking the locking device 5, is partially inserted into a recess space 13 arranged on the rear side of the engagement section 10 of the locking element 6.
- the locking part 12 is designed as a pin, which is molded on in the area of the locking elements 6 during the production of the coupling element 2 made of plastic and is thus firmly connected to the coupling part 2 for assembly.
- a connecting web not shown, between the pin 12 and the coupling element 2 is destroyed by a compressive force.
- the pin 12 is inserted into the recess space 13 so that the deformability of the locking element 6 is restricted and the counter-locking element 7 cannot be guided past the locking element 6.
- the pin 12 is guided out of the recess space 13 or a hollow cylindrical section 14 formed in the recess space 13, so that the locking device 11 is unlocked and the counter-locking element 7 is guided over the locking element 6 in the event of reversible deformation of the locking element 6.
- the coupling element 2 or its leg 4 is pulled out of the cavity formed by the C-profile of the frame part 1.
- Fig. 3 shows a plan view of a further embodiment of a coupling element 2, the two legs 3, 4 are each provided in their end portions with a locking element 6.
- the legs 3, 4 have a plurality of cutouts 15, which saves material and weight.
- FIG. 4 Two further embodiments of the coupling element 2 are shown in FIG. 4, the upper illustration showing a coupling element 2 which is formed on the leg 3 with a latching element 6 according to FIG. 1 and the leg 3 with a notch-like recess 16 for receiving a counter-latching element frame part is executed.
- 4 shows a further embodiment of a coupling element 2, in which the leg 4 having the locking element 6 according to FIG. 1 is designed with recesses 14.
- the leg 3 with the notch-like recess 16 is designed as a web without recesses.
- the frame part 1 has a C-profile-shaped cross section, to which a U-shaped cross-sectional area 20 for accommodating one is not closer shown filter element connects.
- the filter element is designed as a woven or knitted fabric made of metal and preferably made of the same material as the frame part 1. Alternatively, the filter element can also be made of stainless steel.
- the cross-sectional shape of the legs 3, 4 of the coupling element 2 is adapted to the cross-sectional shape of the frame parts in such a way that there is a play-free connection between them in the assembled state, which guarantees an exact shape of the frame.
- a protruding decorative rib is formed on the coupling element, which protrudes beyond the frame part and the adjacent frame part, not shown, so that the decorative rib represents edge protection for the edges of the frame parts in the miter area.
- the frame parts 1 designed as a molded part can be locked and the individual frame parts, which are preferably made of aluminum or an aluminum alloy, can be pre-fixed. Furthermore, an alignment of the miter cuts is given by the clamping force of the latching device, since the frame parts are pressed against one another by the clamping force in the miter area.
- connection of individual frame parts by means of the coupling elements offers the possibility of finally fixing a frame formed from several individual frame parts at once by using a device to fix the respective lig required joining force is applied to the frame parts for locking the legs of the coupling elements in the frame parts.
- the legs can enclose an acute or an obtuse angle with one another in order to form a triangular or a quadrangular or a polygonal frame.
- a triangular suction opening or inflow opening of an extractor hood can be framed with the frame, for example.
- the frame can also serve to surround a circular suction opening of an extractor hood, in which case the coupling element can also be designed in an arc shape.
- the counter-locking element and the locking element of the locking device in a spring-elastic manner and to secure them against independent loosening of the connection between the coupling element and the frame parts by means of a separate locking device.
- the locking element and the counter-locking element can be designed in the same constructive manner as the embodiment of the locking element shown in FIG. 1.
