Description

Title of the invention: Adjustable gate toe plate FIELD OF THE INVENTION

[0001] The present invention relates to an adjustable toe plate composed of a base fixed to the ground and carrying a pivot adjustable in height and in translation in the plane of the gate, the base having a longitudinal slide for adjusting the pivot. STATE OF THE ART

[0002] An adjustable gate toad as defined above is already known.

[0003] PURPOSE OF THE INVENTION

[0004] The aim of the present invention is to develop a gate toe plate which is simple to install and to adjust precisely and independently on the different axes.

[0005] DISCLOSURE AND ADVANTAGES OF THE INVENTION

[0006] To this end, the invention relates to an adjustable gate pivot as defined above, characterized in that it comprises: a base having a longitudinal housing under the longitudinal slide, a gib in the longitudinal housing having a longitudinal thread, parallel to the longitudinal slide and a vertical thread, aligned with the longitudinal slide, a pivot having a smooth upper part forming the pivot axis of the gate, a tool socket integral in rotation with the pivot, a threaded lower part, carrying a locknut under the tool socket and, screwed into the vertical thread of the gib through the slide, an adjustment screw, screwed from the outside of the base, locked longitudinally in the base, and engaged in the longitudinal thread of the gib, the gib being guided in the longitudinal housing and the pivot screwed into the gib, adjustable, the locknut coming on top of the base under the tool socket,the pivot being positioned longitudinally by the adjustment screw and vertically by screwing it into the gib, and the locknut tightening the gib against the slide to block the vertical adjustment and the longitudinal adjustment of the pivot.

[0007] This gate pivot has the advantage of being simple to install and adjust. In particular, the adjustment of the gate pivot is done independently, simply and precisely by positioning the gib with the adjustment screw easily accessible from outside the base and allowing the gib to be positioned only by the screw, a force exerted on the gib cannot cause the rotation of the adjustment screw.

[0008] Adjusting the height of the pivot is just as simple, as it is done by screwing the pivot into the gib, to achieve the correct position. Then, this double adjustment is locked by the locknut which blocks both the gib and the rotation of the pivot.

[0009] The adjustment is thus blocked and insensitive to any adjustment that could be caused by the load of the gate or the vibrations to which the toadstool may be subjected or still to the forces exerted by the gate when it is operated.

[0010] Advantageously, the longitudinal housing is delimited by two guide sides and a support top and the gib has a body in the shape of a rectangular parallelepiped with two guide sides and a support top.

[0011] This shape of the gib facilitates the movement of the gib both in the housing of the base and in relation to the ground on which the gib can rest at least partially.

[0012] In addition, the forces transmitted to the gib can be reduced for adjustment by the support of the lock nut on the top of the longitudinal slide since to carry out the adjustment it is sufficient to slightly loosen the lock nut to, on the one hand, allow the sliding of the gib in its housing and the sliding of the pivot supported by the lock nut on the top of the base, on either side of the longitudinal slide. At the end of the adjustment, the locking of the two adjustments is done by simply tightening the lock nut.

[0013] According to another characteristic, the gib has a sole under the body with two edges in the extension of the sides to serve as support on the ground during the adjustment movements of the gib.

[0014] According to another characteristic, the longitudinal tapping of the adjustment screw with its axis offset relative to the longitudinal axis of the median plane containing the axis of the pivot, with a threaded part and a head, the longitudinal housing has a head housing opening at the end of the base by an access orifice to the screw head, the housing with the head of the screw leaving a clearance relative to the ground and allowing the passage of a part of the sole of the gib.

[0015] This embodiment of the gib and the housing for the adjustment screw head makes it possible to increase the longitudinal adjustment travel without increasing the size of the base.

[0016] According to another advantageous characteristic, the tool grip is in the form of a hexagonal nut, which allows the use of a flat wrench to pivot and adjust the height of the pivot.

[0017] According to another advantageous characteristic, the adjustment screw has a cylindrical head with a hexagon socket which facilitates its integration into the base and into its housing. Brief description of the drawings

[0031] DESCRIPTION OF AN EMBODIMENT OF THE INVENTION

[0032] To simplify the presentation of the adjustments, according to the orthonormal reference of [Fig.l], the plane PM of the gate 300 is defined by the axes (x), (y); the transverse direction (z) is perpendicular to the plane PM and the vertical direction of adjustment of the height of the gate is the direction (y). The axis (y) is the pivot axis of the gate.

[0033] The adjustment of the pivot of the toe plate 100 in the direction of the axis (x) is made in the longitudinal adjustment range (Ax); the adjustment in the direction (z) of the toe plate is made in the transverse adjustment range (Az); the adjustment of the height of the pivot is made in the vertical adjustment range (Ay).

[0034] The portal 300 shown schematically, rests in the lower part on the toad 100 and it is guided by a hinge 200 fixed to the pillar P.

[0035] The installation of the gate 300 begins with the installation of the toe plate 100 which is fixed to the ground S, in principle horizontal, at least in the area receiving the toe plate 100. The ground S and the pillar P or the edge of a wall constitute the infrastructure in which the gate is installed.

[0036] The 100 toad can be adjusted in three independent directions:

[0037] - the transverse direction (z) relative to the plane (PM) of the portal,

[0038] - the longitudinal direction (x) of the portal and

[0039] - the vertical direction (y) of the portal axis.

[0040] According to [Fig.2], the toad 100 is composed of a base 1 fixed to the ground or, more generally, to the infrastructure of the gate by two fixing points PF1,2 in two cups 11 on either side of the plane PM, allowing the adjusted fixing of the base 1, transversely, so that its longitudinal axis (x) is aligned in the plane (PM) of the gate.

[0041] Between the cups 11 of the fixing points PF1,2, the base 1 forms a top 12 provided with a longitudinal slide 14 crossed by the pivot 3.

[0042] According to figures 2, 5 to 8, the base 1 forms a longitudinal housing 13 under the longitudinal slide 14, receiving a gib 2 movable in the longitudinal direction and having a longitudinal thread TL and a vertical thread TV. The thread Ion- gitudinal TL has axis (xl) parallel to axis (x) passing through pivot 3; vertical tapping TV is coaxial to axis (y) of pivot 3.

[0043] The pivot 3, carried by the gib 2, has a smooth upper part 31 defining the pivot axis (y) of the gate and a tool socket 32 ​​integral in rotation with the pivot as well as a threaded lower part 33. This threaded part 33 carries a locknut 34 under the tool socket 32 ​​but above the slide 14. The threaded part 33 is screwed into the vertical thread TV of the gib 2 through the slide 14.

[0044] An adjustment screw 4, free to rotate, but locked longitudinally in the base 1 is engaged in the longitudinal thread TL of the gib 2. The gib 2 is guided longitudinally by its sides 211 between the sides 132 of the longitudinal housing 13. The pivot 3 is screwed into the gib 2 through the slide 14 in an adjustable manner. The locknut 34 comes on top of the slide 14; it is itself surmounted by the tool grip 32. The pivot 3 is positioned longitudinally by the adjustment screw 4 and vertically by its screwing into the gib 2; the nut 34 tightens the gib 2 against the slide 14 to lock the vertical adjustment and the longitudinal adjustment of the pivot 3.

[0045] According to [Fig.9], the base 1 is fixed by two screws 113 housed in the cups 11 on either side of the median plane PM of the base 1.

[0046] In more detail according to figures 2A, 2B, 3, 4A, 4B, the bottom of the cups has an opening 111 on which comes a washer 112 with an oblong hole, orientable in the transverse direction for adjustment in the range Az. The locking in the adjusted position is done using the fixing screws 113 passing through their washer 112 and screwing with a dowel into the infrastructure. The oblong holes of the washers 112 make it possible to position the median plane of the toad exactly in the median plane PM of the portal (adjustment of the axis z). The cups 11 are closed by a clipped cap 114.

[0047] The base 1 is a metal casting, composed of two symmetrical parts forming the cups 11 and their opening 111 of substantially square shape.

[0048] In its middle part, the underside of the base 1 delimited by an edge 10 forms the longitudinal housing 13 into which the slide 14 opens. The longitudinal housing 13 is bordered by a top 131 and two parallel walls 132 forming the two longitudinal guide surfaces of the gib 2.

[0049] The bottom view of [Fig.4B] shows the gib 2 installed in the guide housing 13. The gib 2 is crossed by the adjustment screw 4 whose head 42 is housed, free to rotate, in a housing 15 integrated in the longitudinal housing 13 which thus blocks the screw in translation.

[0050] This housing 15 opens through an orifice 151 through the wall of the base 1 in the axis (xl) of the head 42 to access its imprint 421 with a key, from the outside of the base 1.

[0051] The top 12 of the base 1 ([Fig.3]) bordering the longitudinal slide 14 of the pivot is a flat surface at least at the edge of the slide to form the support surface of the lock nut 34 making it possible to block the adjustment of the pivot 3 in the longitudinal direction by the gib 2 and the vertical adjustment of the height of the pivot 3 relative to the gib 2 and to the base 1.

[0052] This top view shows a washer 112 placed in a bowl 11 and highlighting the transverse adjustment range Az of the base 1. An identical washer 112 is provided for the other bowl 11.

[0053] [Fig.2B] is a cross-section of the adjustable toad 100 passing through the axis (y) of the pivot 3.

[0054] The gib 2 is blocked against the top 131 of the housing 13 by tightening the locknut 34 against the top 13 of the base 1. This sectional view highlights the length of the vertical thread TV which guarantees the stability of the pivot 3 and also thanks to the large contact surface between the top 212 of the gib and the bottom 131 of the housing 13. The forces applied by the moving gate are transmitted to the base 1 resting by its edge 10 on the ground fixing surface.

[0055] The inclined surface of the top of the base 1, completed by the plugs 114, evacuates the runoff water and lightens the appearance of the lateral parts of the base on either side of the closed gate.

[0056] According to figures 5 to 8, the pivot 3 is associated with the gib 2 sliding in the longitudinal housing 13 of the base 1. The gib 2 comprises a vertical thread TV in the axis (y) of the pivot and a longitudinal thread TL with axis (xl) perpendicular to it, receiving the adjustment screw 4 whose head 42 is retained in the housing 15 to longitudinally immobilize the adjustment screw 4.

[0057] According to [Fig.7], the pivot 3 is composed of a smooth part 31 constituting the pivot itself, bordered by a tool grip 32 in the form of a hexagonal nut, integral with the pivot and surmounting the threaded part 33 of the pivot, engaged in the TV tapping of the gib 2 and carrying the lock nut 34.

[0058] The pivot 3 is adjusted (Ax, Ay) in longitudinal sliding in the slide 14, by the displacement of the gib 2, by the screw 4 which passes through it and in height by the screwing of the pivot 3 into the TV thread of the gib. The screw 4 is, preferably, a screw with a hollow hexagonal cylindrical head (TCHC screw).

[0059] The adjustment components for the installation of the base 1 are easily accessible. The same applies to the adjustment components of the gib 2 and the pivot 3. These two adjustments are made by unlocking the locknut 34, positioning the gib 2 by the screw 4 and adjusting the height of the pivot 3 by screwing it in using the tool grip 32 in the form of a hexagonal nut, then locking the two adjustments by the single locknut 34. To make these adjustments, it is sufficient to slightly loosen the locknut 34 so that conversely, after the two adjustments, tightening the locknut 34 will not significantly change the height adjustment of the pivot 3.

[0060] When the adjustments are made, the gib 2 and the pivot 3 are blocked by the lock nut 34 resting on the top 12 of the base 1 and ensuring the blocking by the tightening of the gib 2 in the base 1 and the blocking of the rotation of the pivot 3 by the lock nut 34 blocking the screwing of the pivot 3 in the gib 2.

[0061] Figures 5, 8 show the particular shape of the gib 2 and its combination with the pivot 3; the integration into the base appears clearly in the two sectional views of Figures 2B and 6.

[0062] The gib 2 consists of a body 21 in the shape of a rectangular parallelepiped combined with a sole 22. The body 21 has two guide sides 211 and a top 212 for support and tightening at the end of adjustment.

[0063] The sole 22 forms the support on the ground by its two longitudinal edges 221.

[0064] This shape of the gib 2 is combined with the particular shape of the housing 13 resulting in a very compact base 1 for a large adjustment range Ax. Indeed, the sectional view of [Fig.6] shows the particular shape of the longitudinal housing 13 occupied in part by the housing 15 for the screw head 42 so as to leave a clearance 133 under the housing 15 for the passage in the end-of-travel position, of the end of the sole 22. This shape of the gib 2 makes it possible to have a relatively long vertical tapping TV for the threaded part 33 and also the adjustment travel Ay of the height of the pivot 3 and good support of the sole 22 on the ground S during the longitudinal adjustment Ax of the pivot 3.
