Definitions

  • the present invention relates to a safety device for driving swings, the purpose of which is to prevent sudden shakes or jolts in the driving of the swings, such that with the device of the invention the driving of the swings is ensured without danger to the user, especially when small children are swinging on them.
  • the device of the invention is applicable to the safety of swings to prevent jolts, especially for small children during the driving of the swings, and, furthermore, it is worth pointing out the fact that with the device of the invention it is also possible to stop the mobility of the swings in a smooth, quick and safe way whenever there is a need to do so.
  • Swings basically comprise pairs of elongated elements in combination with seat platforms in which users sit to swing and thus enjoy the swings, and thus said swings normally hang from a support structure made up of two vertical frames in combination with a horizontal bar to which the upper ends of the pairs of elongated elements are anchored, elongated elements such as chains or swing lines, the lower ends of which are connected to the seat platform.
  • the controlled driving of the swing can be difficult, especially when small children are using the swings, usually resulting in a continuous driving of the swing that is not progressive or uniform, which could lead to the instability of the child supported by the seat platform, causing the child to fall to the ground.
  • this act must be done abruptly and is therefore dangerous for the child.
  • each one of these swings comprises a seat platform and flexible swing lines that form part of a main structure that at a lower end connects to the seat platform and at an upper end the main structure couples to an articulated connection located below a horizontal bar that supports the set of the swing that hangs from said articulated connection.
  • the main structure of the swing includes a cross-member located below the articulated connection of the main structure.
  • Said cross-member is joined to the flexible swing lines, interrupting the continuity thereof, such that integrally joined to said cross-member is an arm to which hanging chains connect, with lower handles which a person is able to use to push and/or stop (slow) the swing with their hands, grabbing said lower handles so that during the driving of the swing said cross-member has a swinging motion, distanced from the articulated connection that hangs from the main structure of the swing.
  • the distancing of the cross-member with respect to the articulated connection makes the driving and slowing of the set of swings difficult, precisely due to said distancing, and also because when acting on the lower handles to drive or slow the swing, there is a translational motion of the cross-member that makes the driving and especially the slowing of the swing difficult.
  • Another drawback is that when it is necessary to stop the swing because of an emergency with regard to the child that is on the swing, it is not possible to immediately stop said swing due to the fact that the swing lines are flexible and, therefore, the inertia caused by the swinging motion prevents the immediate stopping of the seat platform on which the child is swinging, thereby resulting in a dangerous situation by delaying the stopping of the swing.
  • Said inertia also makes the stopping of the arm and cross-member set difficult, such that said inertia also tends to displace the user who is handling the actuating device, all of which is due to the inertial translational motion that is generated in said arm and cross-member set, which is separated by a rotational radial distance with respect to the articulated connection.
  • the invention proposes a safety device for driving swings, wherein the swings in principle comprise pairs of elongated structures and seat platforms that hang from said elongated structures, on each one of which a user can sit to enjoy the act of swinging.
  • the safety device of the invention comprises a horizontal cross-member configured to rotate on the longitudinal axis thereof by means of a drive mechanism.
  • the elongated structures of the swings are integrally joined to the horizontal cross-member, wherein the rotation of the horizontal cross-member drives the swings, generating a pendular motion of the same, highlighting the fact that the elongated structures of the swings comprise a rigid structure that maintains their stiffness at all times, both in the mobility of the swings and in the static positions thereof, which substantially facilitates the driving and slowing of the swings, also assisted by the fact that said elongated structures are directly joined to the articulated connection corresponding to the horizontal cross-member.
  • the safety device comprises at least a first drive mechanism that includes:
  • the safety device comprises at least a second drive mechanism that includes:
  • the wheel of the second drive mechanism comprises a lower bar that includes the opposite connections of the wheel to which the ends of the side elements are connected.
  • the wheel further comprises an annular body for gripping and a front plate joined to the annular body for gripping.
  • the opposite connections of the wheel comprise rings.
  • the wheel is coupled to a fixed shaft, wherein said wheel can rotate around said fixed shaft.
  • the fixed shaft is joined to a support joined to one of the two side frames that support the device of the invention.
  • the device of the invention further comprises a fixed stop that limits the rotation of the horizontal cross-member.
  • Said limited rotation of the horizontal cross-member comprises the contact of the upper bar on the fixed stop, which in one embodiment of the invention is located below the upper bar.
  • the elongated structures of the swings comprise pairs of tubes with a telescopic coupling that includes means for regulating and fastening the length of said elongated structures.
  • Said means for regulating the length of the elongated structures comprise holes facing each other located on the pairs of tubes with telescopic coupling, where anchoring screws are inserted in said holes facing each other.
  • the horizontal cross-member is supported by end supports that form part of the side frames, where, in one embodiment of the invention, the horizontal cross-member is supported by said end supports with bearings interposed where the end sections of the horizontal cross-member are embedded, thereby facilitating the rotation of the horizontal cross-member and generally achieving improved functioning of the safety device of the invention.
  • the lower gripping bar may be coupled in an articulate way by the center thereof to a fixed shaft joined to one of the frames.
  • the device of the invention With the device of the invention, one can act directly on the articulated connection from which the set of swings hangs, corresponding to the horizontal cross-member, thereby achieving precise and quick control, both for the driving and for the slowing of the swings; unlike the American patent with publication number US2008/0090667 , wherein the driving and slowing of the swings is more difficult, slower and less precise, due precisely to the difference of the fact that in said patent the articulated connection is not directly acted upon, but rather actuation takes place on a part of the flexible swing lines through a cross-member joined to said flexible swing lines. Said difficulty, slowness and imprecision for driving and slowing the swings is compounded by the flexible structure of the swing lines.
  • the safety device for driving swings comprises a horizontal cross-member 1, with rotational mobility around the longitudinal axis 1a thereof, wherein the rotation of said horizontal cross-member 1 is done by means of a drive mechanism.
  • first ends of pairs of elongated structures 2 that have second ends from which seat platforms 3 hang, in which users sit to be able to swing, either by themselves or by means of a drive mechanism.
  • sections of horizontal crossmembers 1 are coupled to end supports of the side frames 4 with the interposition of bearings 5, such that the incorporation of said bearings 5 facilitates the rotation of the horizontal cross-member 1 during the pendular swinging of the swings fixed to said horizontal cross-member 1.
  • the horizontal cross-member 1 rotates by means of the transmission of a first drive mechanism 6 that comprises an upper bar 7 joined to an end section of the horizontal cross-member 1; a lower gripping bar 8 in the shape of a handle, and two side elements 9 that join the ends of the upper bar 8 and the lower gripping bar 8.
  • said side elements 9 comprise chains.
  • the safety device comprises a second drive mechanism 10 that comprises an upper bar 7' joined to an end section of the horizontal cross-member 1; a rotational wheel 11 and two side elements 9' that join the ends of the upper bar 7' to two opposite connections 12 of the wheel 11.
  • the side elements 9' also comprise chains.
  • the wheel 11 includes an annular body for gripping 13, a front plate 14 joined to the annular body for gripping 13 and a lower bar 8' joined to the front plate 14, wherein the lower bar 8' includes the opposite connections 12 of the wheel 11 to which the ends of the side elements 9' are connected.
  • said opposite connections 12 comprise rings.
  • the wheel 11 is coupled to a fixed shaft 15 joined to one end of a support 16 joined to one of the side frames 4 as shown more clearly in figures 4 and 5 .
  • the wheel 11 makes the swings more appealing to children and is also more easily managed and facilitates the driving of the swings.
  • the user grabs the lower gripping bar 8 with their hands, making a movement that is transmitted to the upper bar 6 and obviously to the horizontal cross-member 1, generating in the same a rotational movement that drives the swings, also generating a pendular motion of the same.
  • the side elements 9 can be shorten or lengthened, thereby placing the lower gripping bar 8 at a higher or lower height.
  • the side elements 9 form part of a single closed-loop chain that passes through the inside of the upper bar 7 and lower bar 8 when they have a tubular configuration, such that in this case the first drive mechanism 6 is adapted to the height of the user who drives the swing, shortening or lengthening the closed-loop chain.
  • a fixed stop 17 is provided on which the upper bar 7, 7' makes contact in the position of maximum amplitude.
  • said maximum angular amplitude is 45°.
  • the fixed stop 17 is joined to an upper part of at least one of the side frames 4, and at the same time said fixed stop 17 is situated below the upper bar 7, 7' joined to the horizontal cross-member 1.
  • the elongated structures 2 of the swings comprise pairs of telescopic tubes 2a, 2b, such that each pair of them is immobilized in relation to one another by means of anchoring screws 18 associated with nuts 19 to ensure the immobilization thereof.
  • One end of each pair of telescopic tubes 2a, 2b is fastened at an upper end to the horizontal cross-member 1, while the seat platform 3 of the swing is coupled to the other opposite lower end of each pair of telescopic tubes 2a, 2b, either directly or by means of a chain structure 20.
  • each pair of telescopic tubes 2a, 2b comprises a first tube 2a of a greater diameter fixed to the horizontal cross-member 1 and a second tube 2b to which the seat platform 3 is coupled.
  • the telescopic tubes 2a, 2b have a succession of holes 21 facing one another in order to be able to change the length of the elongated structures of the swings, such that through said facing holes 21 the anchoring screws 18 are inserted to fix the desired length of the elongated structures of the swings.
  • the lower gripping bar (8) may be coupled in an articulate way by the center thereof to a fixed shaft (15') joined to one of the frames (4).
  • a first option which includes a single drive mechanism 6, 10 placed in correspondence with an end of the horizontal cross-member 1; and a second option which includes two drive mechanisms 6, 10 placed in correspondence with the two ends of the horizontal cross-member 1.
  • the device of the invention is also applicable to wooden swings that are normally mounted in parks and gardens, such that in these cases, in order to mount the device of the invention, all that needs to be done is to first disassemble the horizontal bar from which the conventional swings hang, and then mount the horizontal cross-member 1 together with the bearings 5 and elongated structures 2 thereof joined to said horizontal cross-member 1. To do so, on the upper part of the wooden side frames, supports are fixed to be able to better couple the horizontal cross-member 1 together with the bearings thereof; the operation being relatively simple and fast, since it is easy to work with wood. It is worth noting that 80% of parks and gardens have swings made of wood.
