Description

Title of the invention: Adjustable gate hinge FIELD OF INVENTION

[0001] The present invention relates to an adjustable pivot consisting of a base fixed to the ground and carrying a pivot adjustable in height and 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 pivot as defined above is already known.

[0003] PURPOSE OF THE INVENTION

[0004] The present invention aims to develop a gate pivot that is simple to install and to adjust precisely and independently on the different axes.

[0005] DESCRIPTION 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 holder rotationally fixed to the pivot, a threaded lower part, carrying a locknut under the tool holder and, screwed into the vertical thread of the gib through the slide, an adjusting 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 the top of the base under the tool holder,The pivot is positioned longitudinally by the adjusting screw and vertically by screwing it into the gib, and the locknut tightens the gib against the slide to lock the vertical and 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, which is easily accessible from outside the base and allows the gib to be positioned only by the screw; any force exerted on the gib cannot cause the adjustment screw to rotate.

[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. This dual adjustment is then locked by the lock nut, which prevents both the gib and the rotation of the pivot.

[0009] The adjustment is thus locked and insensitive to the misalignment that could be caused by the load of the gate or the vibrations to which the pivot may be subjected or even by 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] Furthermore, the forces transmitted to the gib can be reduced during adjustment by the locknut bearing against the top of the longitudinal slide, since adjusting it only requires slightly loosening the locknut to allow the gib to slide in its housing and the pivot, which rests against the top of the base via the locknut, to slide on either side of the longitudinal slide. At the end of the adjustment, both settings are locked by simply tightening the locknut.

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

[0014] According to another feature, the longitudinal tapping of the adjusting screw has its axis offset from 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 through an access hole to the screw head, the housing with the screw head leaving a clearance from the ground and allowing the passage of part of the sole of the gib.

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

[0016] According to another advantageous feature, 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 feature, the adjusting screw has a cylindrical head with a hexagonal socket, which facilitates its integration into the base and its housing. Brief description of the drawings

[0031] DESCRIPTION OF A MODE OF EMBODIMENT OF THE INVENTION

[0032] To simplify the presentation of the settings, according to the orthonormal coordinate system of [Fig. 1], the PM plane of the gate 300 is defined by the axes (x), (y); the transverse direction (z) is perpendicular to the PM plane and the vertical direction for adjusting the height of the gate is the (y) direction. The (y) axis is the pivot axis of the gate.

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

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

[0035] The installation of the gate 300 begins with the installation of the pivot 100 which is fixed to the ground S, in principle horizontal, at least in the area receiving the pivot 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 pivot pin is adjustable in three independent directions:

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

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

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

[0040] According to [Fig.2], the pivot 100 consists 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 recesses 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 equipped with a longitudinal slide 14 through which the pivot 3 passes.

[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 longitudinal thread TL has its axis (xl) parallel to the axis (x) passing through the pivot 3; the vertical thread TV is coaxial with the axis (y) of the 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 holder 32 fixed in rotation to the pivot as well as a threaded lower part 33. This threaded part 33 carries a lock nut 34 below the tool holder 32 but above the slide 14. The threaded part 33 is screwed into the vertical tapped hole TV of the gib 2 through the slide 14.

[0044] A free-rotating but longitudinally locked adjustment screw 4 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 is mounted on top of the slide 14; it is itself surmounted by the tool holder 32. The pivot 3 is positioned longitudinally by the adjustment screw 4 and vertically by being screwed into the gib 2; the nut 34 clamps the gib 2 against the slide 14 to lock the vertical and 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, as shown in Figures 2A, 2B, 3, 4A, and 4B, the bottom of the cups connects to an opening 111 onto which rests a washer 112 with an oblong hole, orientable in the transverse direction for adjustment within the Az range. Locking in the adjusted position is achieved using fixing screws 113 that pass through their washer 112 and are screwed into the frame with a dowel. The oblong holes in the washers 112 allow for precise positioning of the pivot plane within the pivot plane PM of the gate (z-axis adjustment). The cups 11 are closed by a clipped plug 114.

[0047] The base 1 is a metal casting, composed of two symmetrical parts forming the bowls 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 view from below of [Fig.4B] shows the gib 2 installed in the guide housing 13. The gib 2 is traversed by the adjusting screw 4 whose head 42 is housed, free to rotate, in a housing 15 integrated into 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 on the edge of the slide to form the bearing surface of the lock nut 34 allowing 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 the base 1.

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

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

[0054] The gib 2 is locked against the top 131 of the housing 13 by tightening the lock nut 34 against the top 13 of the base 1. This cross-sectional view highlights the length of the vertical tapping TV which ensures 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 which rests by its edge 10 on the fixing surface on the ground.

[0055] The inclined surface of the top of the base 1, completed by the plugs 114, drains 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 has a vertical thread TV in the axis (y) of the pivot and a longitudinal thread TL with axis (xl) perpendicular to it, receiving the adjusting screw 4 whose head 42 is retained in the housing 15 to immobilize the adjusting screw 4 longitudinally.

[0057] According to [Fig.7], the pivot 3 consists 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) by sliding longitudinally in the slide 14, by the movement of the gib 2, by the screw 4 which passes through it, and vertically by screwing the pivot 3 into the TV thread of the gib. The screw 4 is preferably a socket head cap screw (SHCS).

[0059] The adjustment components for positioning the base 1 are easily accessible. The same is true of the adjustment components for the gib 2 and the pivot 3. These two adjustments are made by loosening the lock nut 34, positioning the The gib 2 is tightened by screw 4 and the height of the pivot 3 is adjusted by screwing it in using the hexagonal nut-shaped tool holder 32, then locking both adjustments with the single lock nut 34. To make these adjustments, only a slight loosening of the lock nut 34 is required so that, conversely, after the two adjustments, tightening the lock nut 34 will not significantly change the height setting of the pivot 3.

[0060] When the adjustments are made, the gib 2 and the pivot 3 are locked by the lock nut 34 bearing on the top 12 of the base 1 and ensuring the locking by tightening 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 is clearly shown in the two cross-sectional views of Figures 2B and 6.

[0062] The gib 2 consists of a rectangular parallelepiped-shaped body 21 combined with a base 22. The body 21 has two guide sides 211 and a top 212 for support and clamping 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 cross-sectional view of [Fig. 6] shows the particular shape of the longitudinal housing 13, partially occupied by the housing 15 for the screw head 42, so as to leave a clearance 133 below the housing 15 for the passage of the end of the sole 22 into the end-of-stroke position. This shape of the gib 2 allows for a relatively long vertical tapping hole TV for the threaded portion 33 and also the adjustment stroke Ay of the height of the pivot 3, as well as good support of the sole 22 on the ground S during the longitudinal adjustment Ax of the pivot 3.
