Definitions

  • the invention relates to a fabric presser foot for a sewing machine for sewing a filling material into a fabric.
  • a seam that connects two layers of fabric can be designed or designed in many different variations.
  • a possible embodiment of such a seam is the piping or the piping.
  • Both the piping and the piping denote a fold of fabric that is filled with a filling material. Piping is often used as a decorative element on clothing items, such as uniforms, to emphasize the seam.
  • the piping can also be used to reinforce a seam, for example on the edges of trouser pockets or seams on seat upholstery.
  • the piping is very similar in terms of the design or design of the piping, but is mainly used to reinforce the edges of cloth or tarpaulin, so that these edges can be easily inserted into a holder and held in place by it.
  • the filling material is typically a cord, a thick cord, a rope or a plastic-based filling or round cord.
  • the filling material can also be a dimensionally stable rod or a dimensionally stable tube.
  • the filling material is placed on a fabric and the fabric is then folded around the filling material so that the fabric sits snugly against the filling material.
  • the resulting two layers of fabric are placed on top of each other close to the filling material and connected to each other.
  • the two layers of fabric are connected by sewing them together, with the sewing together typically being done using a sewing machine.
  • Special sewing machine feet or sewing machine presser feet or fabric presser feet are known for producing piping or piping with a sewing machine. These are also known as piping feet or piping feet.
  • Such a piping or piping foot typically includes a recess in the sole of the foot, which is designed to guide the filling material next to the sewing machine needle when sewing, so that, using the sewing machine needle to connect the two layers of fabric, a seam is created next to the filling material bordered with the snugly fitting fabric can be sewn.
  • a typical piping foot or piping foot can only sew filling material into a fabric that has a certain spatial extent.
  • the specific spatial extent is determined by the spatial extent of the depression in the sole of the foot.
  • cords with a cord diameter of 3 mm or 5 mm are sewn into a fabric. If the sewing is done using a sewing machine, then a first piping foot is used to produce a piping with a cord that has a 3 mm cord diameter, the recess of which has a spatial extent that matches this 3 mm cord. To produce a piping with a cord that has a 5 mm cord diameter, a different piping foot is used, the recess of which has a different spatial extent that matches the 5 mm cord. The same applies to well-known piping feet.
  • piping feet or piping feet of the prior art can only do one Process the filling material size into a piping or piping and are therefore not very flexible in use.
  • the invention relates to a fabric presser foot for a sewing machine for pressing down a fabric to be sewn onto a needle plate or onto a fabric pusher element of the sewing machine, so that the fabric can be transported in a transport direction during sewing, comprising a shaft for attaching the fabric presser foot to a sewing machine, a needle opening through which the sewing machine needle can be passed through when sewing, and a fabric presser foot sole with an elongated depression in the fabric presser foot sole, the elongated depression extending along its longitudinal direction laterally next to the needle opening, so that the longitudinal direction during sewing runs parallel to the transport direction, the elongated depression forms a guide wall, which is designed, when sewing, to guide a filling material to be sewn into the fabric to be sewn past the needle opening to the side of the needle opening in the transport direction and to press it against the fabric to be sewn, and the elongated recess has an extension L in the longitudinal direction and an extension B in the width and has an extension T in depth, the guide
  • the shaft of the fabric presser foot is typically attached to the presser bar of a sewing machine.
  • the presser bar is usually tensioned by means of a spring and presses the presser foot attached to it down onto the needle plate or the fabric pusher, so that a fabric to be sewn, which lies between the fabric presser foot sole and the needle plate or the fabric pusher, can be clamped and transported in the transport direction.
  • the shaft of the fabric presser foot is therefore used for attachment to a sewing machine, in such a way that the fabric presser foot is pressed down onto the throat plate or the fabric pusher as described above and the fabric to be sewn can be clamped and transported in the transport direction.
  • the shaft can have a receptacle for an end section of the push rod, into which receptacle the end section can be inserted.
  • the fabric presser foot can then be connectable to the presser bar by bracing it against the end section of the presser bar. Bracing can be done, for example, by means of a screw clamping device or a tensioning lever device.
  • the needle opening When sewing, the needle opening allows the sewing needle to be inserted into the fabric to be sewn.
  • the needle opening forms a recess in the presser foot through which the sewing needle can be guided when sewing.
  • the needle opening is typically designed in such a way that it allows for multiple needle positions to be inserted during sewing.
  • the needle opening is designed in such a way that The sewing needle emerges from the fabric, which remains depressed.
  • the fabric presser foot sole is the part of the fabric presser foot that is closest to the fabric being sewn or is in direct contact with it when sewing.
  • the fabric presser foot sole comprises a surface along which the fabric to be sewn is transported during sewing.
  • the fabric to be sewn can be pressed onto the throat plate or the fabric pusher using the fabric presser foot sole and can be clamped in such a way that the fabric to be sewn can be transported in the transport direction.
  • the elongated depression extends to the side of the needle opening, so that when sewing the sewing needle pierces the fabric to be sewn next to the elongated depression.
  • This elongated depression can, for example, be semi-tubular.
  • the elongated depression forms a guide wall.
  • This guide wall is designed in such a way that a filling material, which is to be sewn into the fabric to be sewn to produce a piping or a piping, is guided past the needle opening to the side of the needle opening during sewing.
  • the filling material is typically placed on the fabric to be sewn and this is then placed tightly around the filling material so that the filling material lies between two layers of fabric.
  • the filling material is then bordered with a layer of fabric or covered by a layer of fabric.
  • the two layers of fabric are connected to each other by sewing close to the filling material and at a certain distance from the filling material. To do this, the filling material, covered with a layer of fabric, is placed in the elongated recess of the presser foot.
  • the guide wall is also designed to press the filling material against the fabric to be sewn, i.e. against the enveloping layer of material, so that the filling material can be transported together with the fabric to be sewn.
  • the extent L corresponds to the length in the longitudinal direction of the depression.
  • the extent T corresponds to the depth of the recess in a direction transverse to the sole of the presser foot.
  • the extent B corresponds to the width of the depression in a direction transverse to the depth and to the length.
  • the extent refers to the spatial extent of the depression.
  • the guide wall comprises a guide wall section which is fixed in position relative to the needle opening.
  • Position-fixed means that the position of this guide wall section is fixed or fixed relative to the needle opening.
  • the guide wall also includes a slidable guide wall portion that is slidable relative to the needle opening. Displaceable means that this guide wall section, i.e. its position, is displaceable relative to the needle opening.
  • the displaceability is provided along a displacement direction that runs transversely to the longitudinal direction of the elongated recess.
  • the movable guide wall section can be locked.
  • Lockable means that the displaceable guide wall section can be brought from the state in which it is displaceable into a locked state, in which the displaceable guide wall section is fixed, or blocked, or locked with respect to its displaceability.
  • the displaceable guide wall section can equally be brought from a locked state into a displaceable state.
  • the displaceable guide wall section is displaceable in such a way that an expansion of the elongated recess can be variably adjusted by moving and locking the displaceable guide wall section.
  • An expansion refers to one of the dimensions L, B and T.
  • Variable adjustable means that an expansion can be adjusted differently or is variably adjustable. I.e. by moving and locking the displaceable guide wall section, the expansion can be adjusted differently or the expansion can be variably adjusted.
  • the extent B can be adjusted to a first width and a second width by moving and locking the displaceable guide wall section, the first and second widths being different. The same applies to the other dimensions.
  • the spatial extent of the recess can be adjusted variably. This makes it possible to use the fabric presser foot according to the invention to adapt to the spatial extent of the filling material to be sewn in to adapt.
  • the fabric presser foot according to the invention can therefore be used flexibly and makes the provision of several fabric presser feet for sewing in filling materials with different spatial dimensions unnecessary and thus also the associated changing of the fabric presser foot.
  • the variable adjustability of the spatial extent of the recess is easily made possible by moving the displaceable guide wall section relative to the position-fixed guide wall section and at the same time the guide wall is kept stable. Because only one guide wall section can be moved, the presser foot can also be manufactured more easily.
  • this variable adjustability can be provided by the guide wall having a position-fixed guide wall section and a displaceable guide wall section.
  • the extensions B and T can be variably adjusted by moving and locking the displaceable guide wall section.
  • both the extent B and the extent T can be variably adjusted.
  • the spatial extent of the recess can be adapted in two dimensions to the spatial extent of the filling material. This results in optimal guidance of the filling material, regardless of the set spatial extent of the recess. In particular, this means that the one layer of material that envelops the filling material is pressed firmly against the filling material, regardless of the set spatial extent of the recess.
  • the position-fixed guide wall section has a plane, and the direction of displacement runs parallel to this plane, with the displaceable guide wall section being displaceable along this plane.
  • This plane can form an angle W with the shaft of 0° ⁇ W ⁇ 90°, preferably of 20° ⁇ W ⁇ 70°, more preferably of 30° ⁇ W ⁇ 60°, more preferably of 40° ⁇ W ⁇ 50°, especially include 45°.
  • the position-fixed guide wall section extends between the displaceable guide wall section and the needle opening, the position-fixed guide wall section being designed to hold the filling material in one when sewing to pass the needle opening at a certain distance from the needle opening.
  • the displaceable guide wall section can be displaced along the displacement direction towards the fixed-position guide wall section and/or away from the fixed-position guide wall section.
  • the material presser foot has a displacement device, with a guide which is attached to the material presser foot, and a slider element guided in the guide, the displaceable guide wall section being formed on the slider element, so that the displaceable guide wall section can be displaced by moving the slider element.
  • the guide can be a linear guide, for example.
  • the linear guide then extends along the direction of displacement and parallel to it.
  • the linear guide can be groove-shaped.
  • the slide element can be dimensioned so that it can be guided in the linear guide, in particular in the groove-shaped guide.
  • the slide element can be designed such that the width of the slide element matches the width of the groove-shaped guide, in such a way that the slide element can be guided in the groove-shaped guide.

  • the displaceable guide wall section and the slider element are designed such that the displaceable guide wall section can be removably attached to the slider element.
  • the slide element has male or female plug elements and the displaceable guide wall section has corresponding female or male plug elements, wherein the displaceable guide wall section and the slide element can be plugged together by means of the plug elements.
  • a male connector element may be a male element.
  • the protruding element can, for example, be designed in the shape of a pin.
  • a male connector element is designed to be plugged into a female connector element.
  • a female plug element forms a receptacle for a male plug element and is designed such that the male plug element can be plugged into the receptacle.
  • the female plug element can be a recess which is designed such that a male plug element designed as a projecting element can be plugged into the recess.
  • Such a plug connection enables a simple and secure connection of the guide wall section to the slide element. This makes the fabric presser foot flexible to use and adaptable.
  • the fabric presser foot has a latching device, wherein the displaceable guide wall section can be locked by means of the latching device.
  • the latching device comprises a first latching means and a second latching means, the first latching means being formed on the slide element and the second latching means being formed on the guide and the first latching means being latched onto the second latching means.
  • the first or second locking means can be a pivotally mounted rocker, with a projecting, hook-shaped element being formed at one end of the rocker.
  • the rocker can be pivoted from a rest position under the influence of force, in which case a restoring force which pushes the rocker back into the rest position then acts on the rocker.
