Definitions

  • the invention relates to a screw-in aid for screwing in a long screw at a defined screw-in angle into a subsurface with at least one subsurface section for contact with the subsurface and at least one screw contact section for contacting the screw, the screw-in angle being formed between these.
  • a triangular screw-in aid is known from DE102017119820DE.
  • the three sides essentially form a right-angled triangle in which the hypotenuse is designed for placing a screw.
  • the hypotenuse has an angle in the middle so that screws can be screwed into wood at two different angles.
  • a leg of the triangle serves as a handle. The other cathetus is used to rest on the wood.
  • the disadvantage is that the screw easily slips out of the same when screwing in with such a screw-in aid, for example if the user does not hold the screw exactly in the screwing direction when screwing in the screw with a cordless screwdriver. Often a little wobbling is enough to let the screw slip out of the screw-in aid.
  • the screw-in aid also offers only a small range of functions if you consider the work steps required to screw a long screw into wood at a certain screw-in angle, e.g. keep various bits available for screwing in or set the distance to an adjacent object.
  • the object of the present invention is therefore to provide a screw-in aid that enables the screw to be screwed in securely and preferably offers an even wider range of functions.
  • the object is achieved according to the invention by a screw-in aid with the features of claim 1.
  • the screw preferably has a length of more than 10 cm, in particular more than 15 cm and preferably more than 20 cm.
  • a screw-in aid is usually not necessary for shorter or short screws, since these can usually be guided sufficiently by hand, ie without a screw-in aid.
  • long screws need to be screwed at a certain angle in order to ensure certain load values of the wooden beams to be connected.
  • the substrate preferably consists of or comprises: wood, chipboard, MDF, plastic.
  • the subsurface can then, for example, be in the form of battens, beams, especially roof beams, glued laminated timber, cross laminated timber, laminated veneer lumber or panels.
  • the screw contact section and / or the screw holder advantageously have a groove for receiving the screw therein. This enables good guidance of the screw on the screwing aid and / or the screw holder.
  • the screw holder can be locked to the screw attachment section by means of interlocking latching means, for example latching lugs and latching lug receptacles, and / or can be pushed onto this from one end thereof, for example, guide lugs of the screw holder can be pushed into guide rails of the screw attachment section.
  • interlocking latching means for example latching lugs and latching lug receptacles
  • a second screw contact section is preferably provided which extends from the free end of the subsurface section to the free end of the screw contact section, so that they form a triangle.
  • a second screw contact section and a second subsurface section can be provided, the four sections forming a square and the subsoil sections and the screw contact sections facing each other, with different angles being formed between the respective sections.
  • the screw-in aid and / or the screw holder are advantageously in particular made in one piece from plastic.
  • the screw-in angle is advantageously between 20-90 °, in particular. 30-75 °.
  • At least one spacer is slidably guided in the Eintergrundab section, in particular at a right angle to this, in order to set a desired distance between the screwing aid and an adjacent object, for example an adjacent wooden beam.
  • Two spacers are advantageously provided, which are arranged, in particular, at opposite ends of the cut-out section.
  • a side of the screw contact section facing the screw preferably has at least some sections of a hard surface or a hard support in order to protect the screw contact section from abrasion by the screw when it is screwed in, for example by making the screw contact section facing side made of a harder plastic is formed, in particular from a harder plastic than the rest of the screw-in aid, and / or has a support made from a hard material, for example from a hard plastic or a metal, for example spring steel or steel.
  • the at least one screw contact section advantageously has at least one magnet in order to hold the screw on the screw contact section, for example until the screw holder is arranged on the screw-in aid.
  • At least one insertion opening for a bit is formed in the Eintergroundab section and / or the at least one screw contact section in order to hold at least one bit directly on the screw-in aid for use with a (cordless) screwdriver.
  • the base section advantageously has short and / or thin projections, for example pins or grooves, made of metal or plastic, in order to prevent the screw-in aid from slipping on the base during use. If these are at a certain distance from one another, e.g. 1cm, they can also serve as a marking aid or for marking.
  • the screw holder on the at least one screw contact section comprises, in particular, a longitudinally displaceable bracket on which a cover plate is pivotably mounted, preferably preloaded by means of a spring so that it is pivoted away from the screw contact section in order to apply it in this open state to enable a screw on the screw contact section, and in a closed state when the cover plate rests against the screw contact section to form the closed screw channel (1SK).
  • the screw can be placed on the screw contact section and then the cover plate can be pivoted by hand in the direction of the screw contact section in order to form an at least partially closed screw channel for guiding the screw.
  • the closed screw channel is thus formed by the screw contact section and the cover plate.
  • the advantageously arranged spring holds the cover plate away from the screw contact section, so that a screw can be applied to the screw contact section at any time.
  • the screw contact section and / or the cover plate can have grooves into which the screw can be inserted.
  • the screw holder comprises a flat base as a base plate to rest on the screw contact section and to form the screw channel.
  • a semicircular handle extends from the base on one side in order to handle the screw holder and possibly the screw-in aid connected to it at the same time.
  • four locking feet with locking lugs extend to lock them with guide rails of the screw contact section.
  • the screw holder can be pushed onto the sen with spreading the locking feet outwards perpendicular to the screw contact section in order to lock the locking lugs with the guide rails.
  • the screw holder can also be pushed onto the screw contact section from one end of the screw contact section along its extension, the locking lugs being inserted into the guide rails. grab it. If several guide rails are arranged parallel to one another, the screw holder - depending on the diameter of the screws - can be locked with the screw-in aid at different depths.
  • the screw channel is thus formed by one side of the base or base plate and the screw contact section.
  • the screw holder is connected to the screw-in aid or they are disconnected from each other.
  • a groove can advantageously be formed in the base and / or the screw channel in order to receive the screw therein.
  • FIG. 1 shows a screw-in aid 1 according to the invention with screw holder 3 in various views.
  • the screw-in aid 1 has a triangular shape in which the longest side of the triangle forms a subsurface section 1U1 for contact with a subsurface 7 and the other two sides form screw contact sections 1S1, 1S2 for contact with screws 5.

  • the two screw contact sections 1S 1, 1S2 run at different angles to the subsurface section 1U1: the shorter section runs at an angle of 45 ° and the longer section at an angle of 60 ° to the subsurface section 1U1. Otherwise, the two sections have the same structure.
  • a respective groove IN for receiving a screw 5 runs centrally.
  • the groove IN has a substantially V-shape in cross section.
  • a support 1 A for screws 5 is arranged, which consists of a spring steel and is firmly locked to the respective screw system section 1S1.
  • the support 1A protects the screw contact section 1S1 when the screw is screwed in from friction, which would damage the screw contact section 1S1.
  • 1S2 guide rails 9A are arranged, which run parallel to each other. Once in the middle and once at the end of the guide rails 9A, an insertion surface 9E is formed on both opposite sides. The insertion surfaces 9E are used for inserting locking feet 3R of the screw holder 3, as described below.
