FR2631372A1 - Installation of fixed door frame - using triangular support frame with telescopic strut - Google Patents

Abstract

The fixed frame of a door is placed in the correct position, before being fixed to the surrounding wall, by means of a supporting frame. The frame has a plate (2) to support each door post. This plate can be adjusted for height by a screw (9). The door frame is held vertically by a telescopic strut (3) which is fastened to the upper end of the doorpost by a screw clamp (21). The lower end of this telescopic strut is fastened to one end of a horizontal telescopic arm which has its other end attached to the support plate (2). USE - Fitting of fixed door frames.

Description

DOOR HOLDER
The present invention relates to a device for wedging door frames with horizontal and vertical adjustment.

It is intended to allow the installation and maintenance of door frames in the field of traditional construction.

Currently, to obtain an equivalent result, use is made of corners, various temporary and precarious fixings, such as nailed boards, wire, etc., which gives a very imprecise result or requires a lot of trial and error. and therefore time. In addition, at least two people are required to perform this work.

The device according to the present invention eliminates all these drawbacks. Indeed, it allows a single man to set up a door frame very quickly and to ensure horizontal and vertical adjustment with great precision.

It is constituted by the combination first, of two wedges of height with micrometric adjustment allowing to level the two feet of the frame separately, and thus simultaneously ensuring its verticality in the plane of. the door then, of two integral telescopic arms forming an acute angle between them, one of which, horizontal, is connected to one of the height shims and the other is fixed in the upper part of the frame, thanks to a system of tightening comprising two screws intended to control the verticality in the perpendicular plane finally, of a plumb line consisting of a mass, a cord and a square provided with a hole allowing its fixing to the frame, and facilitating the handling thanks to the presence of a handling ring.

In the accompanying drawings, given by way of nonlimiting example, of one of the forms of the invention
Figure 1 shows the device as a whole.

Figure 2 shows in section the fixing in the upper part of the frame.

Figures 3- and 4 show a height block, respectively in plan with holding the upright by clamping, and in section with removable lifting part.

Figure 5 is a perspective view of the plumb line.

The device, FIGS. 1 to 5, consists of two wedges of height 2, of a telescopic arm 3 for holding the frame 1, of a telescopic arm 4, horizontal, connecting the base of the above to one of the wedges of height 2 and a plumb bob composed of a square 5, a cord 6 and a weight 7.

The height wedges 2 include a sole 8 provided with three screw jacks 9, 10, 10 'allowing a correct leveling whatever the irregularities of the ground, as well as two threaded bosses 11, 11' receiving the tightening screws. 12, 12 'intended to hold the frame 1 when the space between it and the ground prohibits the use of the lifting part 15. The threaded rods constituting the jacks 9, 10, 10' are actuated by pins passed through the holes 13, 14 located in their upper part.

The lifting part 15 is used when the space under the frame is sufficient and allows adjustments to be made by acting only on the threaded sleeve 16 provided with a locking ring 17. The part 15 is removable, so as not to prevent the use of the frame clamping screws 12, 12 '.

The telescopic arm 3 consists of concentric tubes held in position by the pins 18, 18 '. The smaller diameter tube 19 has a series of holes 20, and at its end an articulated part 21 provided with two clamping screws 22, 22 '. The angle of the frame 1 is adjusted by first acting on the length of the arm 3 by choosing the hole 20, then by making a precise adjustment using the screws 22, 22 '.

The arm 4 is fixed on the one hand to the base of the arm 3 using the bolt 23 and the wedge 24, or by any other means, and on the other hand to one of the wedges of height 2 thanks to a hole through which the threaded rod of the jack 10 can pass. The telescopic arm L is kept in the open position by pin 25.

The square 5 of the plumb line has the particularity of being able to be fixed to the frame 1 during the operations thanks to a hole 26 allowing the passage of a point. This provision avoids false balance. In addition, handling is facilitated by the ring 27 acting as a handle.

 Thanks to its simplicity, its reduced volume once folded, its low cost and especially the time it saves, the device which has just been described lends itself particularly well to the production of tools intended also both to bricklayers and masonry companies.

The positioning of the various constituent elements gives this device a maximum of useful effects which had not been obtained to date by similar devices.

However, the shapes, dimensions - and arrangements of the various elements as well as the materials used for their manufacture may vary within the limit of equivalents, without changing - for this, the general conception of the invention which has just been described.

Claims (1)

CLAIMS 10Device for wedging door frames with horizontal and vertical adjustment, characterized by the combination of two independent height shims (2), making it possible to level the two feet of the frame (1) separately and to ensure its verticality in the plane of the door, formed by a sole (8) comprising threaded bosses (11, 11 ') receiving the clamping screws (12, 12') intended to hold the frame (1), and micrometric adjustment jacks ( 9, 10, 10 ') consisting of threaded rods provided with holes (13, 14) for the passage of an operating spindle, with on the one hand two telescopic arms (3, 4) made integral by means of assembly (23, 24), held in the open position by pins (18, 18 ', 25) and forming an acute angle between them, one of which (4), horizontal is connected to one of the height shims (2) thanks to a hole allowing the threaded rod of the jack (10) to pass and the other (3), of just a length, is fixed in the upper part of the dorma nt (1), thanks to a clamping system (21) with two screws (22, 22 ') articulated on the last element (19) of the arm (3) and intended to hold the frame (1) and to control its verticality in the perpendicular plane, and on the other hand a plumb line formed by a mass (7), a cord (6) and a square (5) provided with a fixing hole (26) and d 'a handling ring (27).  20 Device according to claim 1, characterized in that the height shims (2) can be equipped with lifting parts (15) removable, carried by threaded sleeves (16) provided with locking rings (17), sockets (16) screwing onto the cylinder (9), the lifting parts (15) sliding under the right feet of the frame (1) when the space between them and the ground is sufficient.
