Definitions
- the present invention relates to a device for assembling panels or other elements by screwing with a screw housed in the thickness of the panel and not projecting from the panel before screwing.
- the device also does not require any part projecting into the other panel as is currently the case in existing devices, in particular those known as “eccentric”.
- This advantage will allow assemblies in all situations where there is no recoil for the insertion of protruding parts, for example for mounting between two walls.
- Another advantage of this device is to allow the insertion of the screws when preparing the panels and not to have flying parts thus eliminating the risk of loss or 'error and facilitating the implementation and instructions.
- This device concerns both wood or chipboard screws as well as bolts with various threads.
- the device is made up of four main parts: two fixed parts, the body and the sleeve and two moving parts, the socket and the screw, the fifth part being the screwing tool. It is a simple and economical device.
- the socket and the screw are captive of the body and the sleeve.
- FIG 1 in longitudinal section, shows the screw (5) in the retracted position and the screwing tool ready to rotate the socket.
- FIG 2 shows the screw (5) in the extended position and its head supported on the guide sleeve (6).
- FIGS 3 and 4 show the body (1).
- the body is in the shape of a cigar (1) with an external thread (2) making it possible to hold it to the material in which it is inserted and has one or more windows (3) allowing the passage of the tool.
- the window can be closed by a toothed wheel forming a stopper and having an imprint allowing it to be actuated with the tool.
- the sleeve (4) is formed by a hollow housing, with a hexagon or indifferently of a another shape, elongated to receive the head of the screw; it is provided on its rear part with a notch forming a toothed wheel and an axis for its centering which will also have the role of limiting the penetration of the tightening tool.
- the rear axis of the sleeve (4) is cylindrical and can end in a spherical shape.
- the screw (5) is characterized by a head inserted in the housing of the socket and an interrupted thread near the head thus allowing, by a refinement of the body of the screw, to release it at the end of the stroke for tightening.
- the guide sleeve (6) is a hollow cylinder inserted into the body and integral with the latter, comprising a threaded part and optionally a housing (9) for a return spring pushing the screw backwards.
- the guide sleeve is secured to the body of the device by any means depending on the nature of the construction material of the device; for example by gluing or by a pin (8).
- the screw is driven forward at the start of its travel, by the thread of the guide sleeve, to meet the element in which it will be inserted, then, in order to carry out the tightening, it will be released at the end of its travel while it will be in abutment on the rear of the guide sleeve.
- the movement is easily transmitted to the socket, through a window in the body of the device corresponding to a discreet drilling of the panel, using a manual tool, a screwdriver whose grooved shape is adapted to the toothed wheel. socket, or a screwdriver bit on a mechanical or electric tool.
- the hole in the panel serves as a guide and holds the tool.
- the device permanently requires only a toothed wheel, that of the socket, and the gear is formed by the use of the tool.
- the rotational movement imparted to the toothed wheel is transmitted by the sleeve to the screw, while leaving the head of the screw free to move forward or backward.
- the drive is done by a housing in the body of the socket or indifferently by fingers extending a toothed wheel and forming the same mechanism.
- screwing will be carried out directly in the material or in an insert integral with the material. When unscrewing, the screw quickly meets the thread of the sleeve, which allows it to fully retract.
- the device will have dimensions of 8 to 10mm in diameter and 6 to 8cm in length for insertion into panels 19mm thick.
- the device according to the invention is particularly suitable for mounting closets and bookcases from wall to wall and from floor to ceiling by allowing the handling of large panels without the need to step back to place the fittings. It will also be well suited to pre-assembled furniture or delivered as a kit and we can, in order to facilitate assembly by easy centering of the panels, create a withdrawal of the guide sleeve corresponding to a slight projection of the threaded part on the 'other room.
