Definitions

  • the present invention relates to a gate closer which is suited to be retrofitted onto a gate which is hingedly suspended on a side of a support by means of an eyebolt hinge.
  • the eyebolt hinge by means of which the gate is suspended on the support comprises a hinge element mounted onto said side of the support, a hinge pin arranged on said hinge element, and an eyebolt.
  • the eyebolt has an eye portion that is hinged according to a hinge axis about said hinge pin onto said hinge element, and a bolt portion extending through a fastening member on the gate projecting from said side of the gate.
  • the bolt portion of the eyebolt has a projecting portion having a free end, and projecting, at the side of the fastening member facing away from said hinge pin, over a distance from the fastening member of the gate.
  • the fastening member is clamped between two adjustment nuts on the bolt portion of the eyebolt.
  • the adjustment nuts are provided for adjusting the distance over which the bolt portion of the eyebolt projects, and thus the distance between the gate and the support.
  • the gate closer to which the invention relates comprises a body, an actuating arm which is mounted rotatably according to a first rotational axis onto said body, an actuator in said body for actuating the rotating actuating arm and a coupling mechanism for coupling the actuating arm onto the bolt portion of the eyebolt.
  • the body of the gate closer is further configured to be mounted below or above said eyebolt hinge onto said support with said first rotational axis substantially parallel to said hinge axis.
  • Such a gate closer is known from EP-A-3 162 997.
  • the actuating arm of this known gate closer has an upright end in which a vertical elongated hole is arranged, through which the bolt portion of the eyebolt is to be arranged.
  • a small block is arranged in the elongated hole in the actuating arm, having an opening that fits precisely around a nut screwed onto the bolt portion of the eyebolt.
  • the vertical edges of the opening in the block are somewhat rounded so that the block can slightly rotate in relation to the nut on the eyebolt.
  • Such a rotation is required if the rotational axis of the arm does not fully coincide with the hinge axis of the eyebolt hinge.
  • the block itself can slide up and down over a small distance in the elongated hole in the actuating arm, which is required to allow tolerances in the vertical position of the gate closer on the pole to be absorbed.
  • the sliding up and down of the block is further also required if the rotational axis of the actuating arm is not entirely parallel to the hinge axis of the eyebolt hinge.
  • the upright end of the actuating arm is adapted to be arranged onto the eyebolt between the eye portion of the eyebolt and the projecting fastening member.
  • the nut with which the block is to cooperate is also meant to be arranged in this location.
  • a further disadvantage of the known gate closer is that the actuating arm can only be of limited length, as it needs to be on the gate between the eye portion of the eyebolt and the projecting fastening member, even when the gate is at a minimal distance of the support. This causes large forces to occur, as a result of the angular momentum that the gate closer needs to exert onto the gate, between the end of the actuating arm and the eyebolt. Because of the vertical distance which always exists between the location where the actuating arm is mounted onto the body of the gate closer and the bolt portion of the eyebolt, large torsional forces are thus exerted onto the actuating arm.
  • the invention now aims to provide a novel gate closer which can be retrofitted onto the gate without having to remove the gate from the support, and wherein, for a same angular momentum that can be exerted by the gate closer onto the gate, smaller torsional forces are exerted onto the actuating arm.
  • the gate closer according to the invention is characterized in that said coupling mechanism comprises an inner sleeve arranged to be screwed over the free end of the bolt portion of the eyebolt onto the projecting portion of said bolt portion, and an outer sleeve which is arranged onto the inner sleeve so as to be slidable back and forth in the longitudinal direction of the bolt portion of the eyebolt, and which is mounted onto the actuating arm so as to be rotatable about a second rotational axis, which is parallel to said first rotational axis.
  • the actuating arm of the gate closer is coupled with the portion of the eyebolt that projects through the projecting fastening member of the gate.
  • the gate does not need to be disassembled for the gate closer to be retrofitted onto it. Consequently, a further major advantage of the gate closer is that the distance between the first rotational axis, being the axis around which the actuating arm rotates, and the second rotational axis, being the axis around which the coupling mechanism rotates between the actuating arm and the eyebolt, is substantially larger than in the known gate closer.
  • a substantially smaller force needs to be exerted by the coupling mechanism onto the eyebolt to achieve the same angular momentum onto the gate.
  • the force can for instance be over two times smaller, or even smaller, particularly if the distance between the first and second rotational axes is greater than the distance between the hinge axis and the free end of the eyebolt.
  • the torsional forces that are exerted onto the actuating arm and onto its bearings are thus substantially smaller as well, particularly smaller by the same amount as the force exerted by the coupling mechanism onto the eyebolt.
  • said outer sleeve has an open end, allowing the inner sleeve to be screwed through the outer sleeve onto the projecting portion of the eyebolt.
  • This embodiment allows the coupling mechanism to be arranged onto the eyebolt or to be removed from it when the gate closer is mounted onto the support.
  • the gate closer can thus first be mounted onto the support in the correct position below the eyebolt hinge, before coupling its actuating arm with the eyebolt of the eyebolt hinge.
  • there is a relatively large gap between the eyebolt and the outer sleeve allowing, with a correct selection of the various dimensions, the outer sleeve to be tilted over the free end of the eyebolt by a combined rotational movement of the outer sleeve around the second rotational axis and of the actuating arm around the first rotational axis.
  • said outer sleeve has an inner diameter and a free end arranged to be mounted over the projecting portion of the eyebolt, said second rotational axis is located at a first distance from said first rotational axis and said second rotational axis is located at a second distance, measured along the longitudinal direction of the outer sleeve, from the free end of the outer sleeve, wherein said inner diameter, said first distance and second distance are determined so that, when the gate closer is mounted below the eyebolt hinge with said first rotational axis in line with the hinge axis, said outer sleeve, by rotating the actuating arm about said first rotational axis and by rotating the outer sleeve about said second rotational axis, can be mounted or removed over the projecting portion of the eyebolt in the absence of the inner sleeve.
  • the outer sleeve When the actuating arm is made longer, or i.o.w. when the first distance is greater, the outer sleeve is already more tilted during its mounting onto the free end of the eyebolt when it starts contacting the eyebolt. As the outer sleeve thus only needs to be rotated further over a smaller angle before coming in line with the longitudinal axis of the eyebolt, the difference between the inner diameter of the outer sleeve and the outer diameter of the eyebolt does not need to be as large to allow the outer sleeve to be tilted onto the eyebolt. Moreover, the inner diameter of the outer sleeve is evidently also of importance to allow the outer sleeve to be tilted over the free end of the eyebolt. The greater this inner diameter, the faster this becomes possible.
  • said first distance and said second distance are determined so that, when the gate closer is mounted below the eyebolt hinge with said first rotational axis in line with the hinge axis, said outer sleeve overlaps with the eyebolt over a third distance, which third distance is at least 45%, preferably at least 50% and more preferably at least 55% of the inner diameter of the outer sleeve.
  • said first distance is smaller than the distance between the hinge axis and the free end of the eyebolt plus the inner diameter of the outer sleeve.
  • the bolt portion of the eyebolt has an outer diameter and said outer sleeve has an inner diameter which is at least 15%, preferably at least 20% greater than the outer diameter of the bolt portion of the eyebolt.
  • said actuator comprises a motor, particularly an electric motor or a hydraulic motor.
  • the motor is preferably arranged to rotate said actuating arm in both directions, so that the gate closer is not only provided for closing the gate but also for opening it.
  • said motor is locked inside the body of the gate closer by means of a locking mechanism, and the motor can be released by means of this locking mechanism to allow the actuating arm to be rotated manually.
  • This locking mechanism preferably comprises a cylinder lock operated by means of a key.
  • said actuator comprises a spring arranged to urge said actuating arm in in one direction for closing said gate, and to be tensioned upon rotating the actuating arm in the other direction, when opening said gate.
  • said actuating arm is mounted onto the body of the gate closer by means of a double ball bearing.
  • a double ball bearing allows the torsional forces exerted onto the actuating arm to be absorbed in an efficient manner.
  • Each of both ball bearings can therefore be made relatively light.
  • the body of the gate closer is configured to be mounted onto said support with said first rotational axis substantially lying in line as an extension of said hinge axis.
  • the actuating arm is provided with an opening
  • the outer sleeve is provided with a protrusion that fits into said opening and is able to rotate therein according to said second rotational axis.
  • said protrusion has a free end into which a bolt is screwed to fix said protrusion in said opening.
  • said inner sleeve has a cylindrical outer casing and said outer sleeve has a cylindrical inner casing.
  • Such sleeves are not only easy to produce, but moreover occupy only a minimal volume, which benefits the elegance of the gate closer.
  • the invention further relates to a gate which is mounted to a support by means of an eyebolt hinge, and onto which a gate closer according to the invention is arranged.
  • Figure 1 shows a perspective view of a gate suspended from a pole by means of an eyebolt hinge, wherein a gate closer according to the invention is arranged on the eyebolt hinge;

  • Figures 3 and 4 respectively show a front view and a top view of the gate suspended from a pole by means of an eyebolt hinge, which is provided with a gate closer as shown in figures 1 and 2;

  • Figure 9 shows the same front view as figure 7, but with the distance between the pole and the gate increased by means of the eyebolt hinge;
  • Figure 10 shows the same front view as figure 7, but with the projecting fastening member of the eyebolt on the gate fixed to the gate by welding, instead of being mounted thereto with adjustable height;
  • Figure 1 1 shows the same perspective view as figure 1 wherein the gate closer comprises a spring instead of a motor for closing the gate; and
  • Figure 12 shows a front view of the gate suspended from a pole by means of an eyebolt hinge, provided with a gate closer as shown in figure 1 1 , wherein the eyebolt hinge and the gate closer with spring are shown in longitudinal cross section view
  • the gate 1 shown in figure 1 is hingedly suspended at the top and at the bottom (not shown) from a support 3, more specifically from a pole, by means of a height adjustable eyebolt hinge 2.

  • a rail 4 is welded against the lateral side of the gate.
  • a slidable gliding piece 5 is provided, into which two bolts 6 are screwed. With these bolts 6, a fastening member 7 projecting from the front of the gate 1 is mounted onto the gate 1 at an adjustable height.
  • the projecting fastening member 7 is provided with an elongated hole 8 for attaching the eyebolt 9 of the eyebolt hinge 2.
  • the eyebolt hinge 2 comprises a U- shaped hinge element 10 that is attached to the front of the pole 3, particularly by welding.
  • a hinge pin 1 1 is provided on this hinge element 10.
  • the eyebolt 9 has an eye portion 12 that is hinged according to a hinge axis 13 onto the hinge pin 1 1 .
  • the eyebolt 9 further comprises a bolt portion 14 extending through the elongated hole 8 in the projecting fastening member 7.
  • the bolt portion 14 of the eyebolt 9 thus has a portion that projects from the fastening member 7 of the gate over a distance, and that comprises the free end of the eyebolt.
  • two adjustment nuts 15 are screwed onto the bolt portion 14 of the eyebolt 9 on either side of said fastening member 7, between which the projecting fastening member 7 is clamped.
  • the adjustment nuts 15 allow the distance from the gate 1 to the pole 3 to be adjusted, whereby the distance over which the bolt portion 14 of the eyebolt projects from the fastening member 7 also varies.

  • the inner sleeve 22 preferably has a length so as to be screwable over the free end of the eyebolt 9 up against one of the two adjustment nuts 15. Not only does this allow the inner sleeve 22 to be fixed onto the bolt portion 14 of the eyebolt 9, by screwing the inner sleeve 22 sufficiently tight, but the inner sleeve 22 also provides a strengthening of the projecting portion of the eyebolt 9. In this way, the eyebolt 9 can better resist the considerable forces exerted onto it by the gate closer 16.
  • the outer sleeve 23 herein preferably has an inner diameter that is preferably at least 15%, and more preferably at least 20% greater than the outer diameter of the bolt portion 14 of the eyebolt 9. The greater this difference in diameter, the further the outer sleeve 23 can be tilted over the eyebolt 9, and thus, the stronger the connection between both.
  • the actuating arm 18 first of all needs to be of sufficient length. If the free end of the eyebolt 9 is located at a distance 29 (indicated in figure 8) from the hinge axis 13, and the second rotational axis 24 is at a first distance 30 from the first rotational axis 19, this first distance 30 needs to be sufficiently large when compared to the distance 29, wherein, however, the first distance does not always need to be larger than the distance 29 but may also be somewhat smaller. The smaller the first distance 30, the further the outer sleeve 23 will be able to be tilted over the eyebolt 9. Preferably, therefore, the first distance 30 is smaller than the distance between the hinge axis 13 and the free end of the eyebolt 9 plus the inner diameter of the outer sleeve 23.
  • the second distance For a predetermined first distance 30, the second distance
  • the distance 31 being the distance 31 between the second rotational axis 24 and the free end of the outer sleeve 23 which is installed over the eyebolt 9, measured along the longitudinal direction of the outer sleeve 23, should be sufficiently small for the outer sleeve 23 to be tiltable onto the eyebolt 9 by rotating the actuating arm 18 around the first rotational axis 1 9 and rotating the outer sleeve 23 around the second rotational axis 24.
  • the second distance 31 should preferably be chosen to be sufficiently large for the distance over which the outer sleeve 23 extends over the eyebolt 9, hereafter called third distance 32, to be sufficiently large.
  • this third distance 32 i.e. the distance of the overlap between the outer sleeve 23 and the eyebolt 9 is important.
  • this distance 32 is larger when the rotational axis 24 of the outer sleeve 23 is at a larger second distance 31 from the free end of the outer sleeve 23.
  • the first distance 30 is preferably chosen to be sufficiently small, and the second distance 31 to be sufficiently large, so that when the gate closer 16 is mounted below the eyebolt hinge 2 with the first rotational axis 19 in line with the hinge axis 13, the third distance 32 is at least 45%, preferably at least 50% and more preferably at least 55% of the inner diameter of the outer sleeve 23.
  • the first distance 30 is about 80% of the inner diameter of the outer sleeve 23 larger than the distance 29 between the hinge axis 13 and the free end of the eyebolt 9, and the second distance is about 143% of the inner diameter of the outer sleeve 23.

In figure 7, for instance, the gate is closer to the support 3 than in figure 9. It is important to note that the distance 32 over which the outer sleeve 23 overlaps with the eyebolt 9 always remains the same. The strength of the coupling mechanism 21 thus also remains the same.
  • the sliding connecting between both sleeves 22, 23 further offers the advantage that the gate closer 16 does not need to be mounted correctly onto the support 3 below the eyebolt hinge 2, with the rotational axis 19 of the actuating arm 18 in line with the hinge axis 13.
