FR2561970A1 - Removable vice/press - Google Patents

Abstract

Vice/press allowing a part to be clamped on a workbench or any other plane of any dimension and at any place on the working surface. It is composed of a removable jaw of any length composed of two identical elements 1 connected by spacers 2 leaving a space allowing the clamping screws 4 to pass which perpendicularly pass through the workbench or two removable grippers on the working plane side and are housed in a nut. The vice/press may be placed at any place on the working plane because the separation of the clamping screws can vary inside the spaces between the spacers 2. The vice/press can be used on the same horizontal plane as the working plane to obtain a vertical clamping. The vice/press can be used as an independent press by adding a second jaw.

Description

 The present invention relates to a vice press for clamping a workpiece on a workbench. or on any other level.

 It is often difficult to hold a piece on the horizontal plane of the workbench. The use of a valet or clamps is often impractical, the part is not often maintained & the ideal place to work it.

 The present invention easily allows the maintenance of a part regardless of its surface at any location on the work surface.

 The device according to the invention is composed of a jaw of any length taking place perpendicular to the work surface. This jaw is held and clamped by two clamping screws which pass through the workbench or two removable clamps tightened on the edges of the workbench and are housed in a nut.

 Figure 7 shows in perspective the device clamping a workpiece on a workbench crossed by the clamping screws.

 Figure 2 shows eh cuts the clamping through the opening of the workbench.

 Figure 3 shows in section the tightening using a nut clamp fixed on the edge of the workbench.

Figure 4 shows the possibility of maintaining a part at the end of the jaw
Figure 5 shows schilematically possible positions using the openings in the workbench or using pliers.

 Figure 6 shows in perspective the jaw in a horizontal position at the end of the workbench.

 Figure 7 shows the use in independent press by adding a second jaw.

 The device is therefore characterized - fig. 7 - by a jaw made up of two identical elements (7) connected by means of spacers (2) thus leaving a space (3) allowing the passage of the tightening screws (4) and making it possible to vary the spacing of these screws by according to needs.

 These clamping screws (4) actuated by a crank (7) can pass through the workbench - fig. 2 - by a circular opening (10) made vertically throughout the thickness of the workbench (11) and are then housed in the nut (5) fixed under the workbench. Or * according to the -fig. 3 - these clamping screws (4) n. fit in the nut of a removable nut clamp (6) tightened on the edges of the workbench.

 The jaw is maintained - fig. 2 - on the clamping screw for example between a washer (8) at the top, covering the maximum of the surface on the top of the jaw for good support, and a washer (9) at the bottom, held by a removable pin ( 3) thus allowing the clamping screw to be removed. This can be replaced between other spacers.

 In - fig. 3 - another example of holding the jaw at the bottom is shown by a removable clip (i3) taken in a groove made in the clamping screw and a groove running over the entire length of the two inner faces of the jaw.

The workpiece can be clamped at the end of the jaw - fig. 4 - by tightening the screw closest to the part (4-A) and by lifting the other part of the jaw using the screw (4-B)
On the -fig. 5 - we can see examples of positioning made either with holes (10) made through the workbench, or with the nut-pliers (6). The vise grip can be used as a saw guide.

 Another use is described - fig. 6 - The vice press being positioned in the same horizontal plane as the workbench on all or part of one side of the latter. This position allows vertical clamping of the workpiece. To do this, simply add a piece of wood (12) fixed in the same plane as the cat under the workbench (11), making sure that the total thickness obtained is at least equal to that of the jaw. screws (4) are housed in nuts fixed horizontally under the workbench or on the sides.

 A nut - not drawn - made in a suitable way to be oriented on a horizontal and vertical axis and which will be fixed on the side of the workbench will allow the vice to be used on both planes without having to fully unscrew the clamping screw.

 The vice press can also be used as an independent press - fig. 7 - by the addition of a second clamped jaw on the part to be maintained using corresponding nuts, for example the nut pliers (6). This use allows for example to keep flat a set of boards glued to the edge.

 When the jaw is used according to FIG. T, that is to say perpendicular to the work surface, it can serve as a support for parts which it is desired to glue at a right angle.

 it should also be noted that the vice can be placed anywhere - fig. 5 - thanks to the movable jaw whose length is calculated to cover up to the diagonal of the work plan, allowing it to be placed at any place on this work plan, the space left between the spacers (2) allowing the clamping screws (4) to be positioned at any location.

Claims (8)

 1) Vise press characterized in that it comprises a removable jaw made up of two identical elements (1) connected by spacers (2) delimiting a central space through which pass two clamping screws (4). The fixed jaw being formed by the surface of the workbench or the work surface (11)  2) Vise press according to claim 1 characterized in that the clamping screws (4) pass through the work surface (ii) through openings (70) at their diameter for title taken in nuts (5) fixed under the plane of work.  3) Vise press according to claim 1 characterized in that the clamping screws (4) are taken in the nut incorporated in removable pliers (6) provided with fixing means on the edges of the working plant (11).  4) Vise press according to claims 1 to 3 characterized in that the length of the movable jaw is calculated to cover up to the diagonal of the work plan, allowing it to be placed anywhere on this work plan , the space left between the spacers (2) allowing the clamping screws (4) to be positioned at any location.  5) Vise press according to any one of claims 7 to 4 characterized by the washer (9) placed under the jaw and held by pin (3) to the screw (4) allowing to act in opposite direction, so to clamp with the jaws of the jaw a workpiece by tightening with the clamping screw (4-A) closest to said part and by exerting an upward pressure on the other part of the jaw using the other screw (4-B).  6) Vise press according to claims là3 characterized by a part (12) intended to be fixed under the work plan allowing to tighten in the same plane as the work plan1 at the end thereof, when the clamping screws ( 4) are taken in nuts fixed horizontally either under the work surface, or on the side thereof.  7) Vise press according to claims 1 and 3 characterized by removable or fixed pliers whose nut is oriented horizontally, to receive the screws (4) at the end of the work surface.  8) Vise press according to claim 1 characterized by the addition of a second removable jaw intended to be crossed by the clamping screws (4) constituting an independent press.
