Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a system for freely passing support or attachment points for an elongated element or series of elongated elements along a path defined by the elongated element or series of elongated elements. This invention relates to a device that can move cargo.

Such a device is described in British Patent No. 1582201, co-owned by the present application, and the present invention provides an improvement or variation on the type of device disclosed in that British patent.

The device of the present invention may be made of flexible elongated members such as wires or cables or rigid elongated members such as rods or tubes, which are often used in the arts including, for example, architecture, quarrying, agriculture, and the civil engineering industry. This overcomes the disadvantage of having to attach and detach the device at the portion of the support member that supports the elongated member in order to move the load along a defined elongated track. Therefore, this device has safety, mobility,
It can satisfy many demands such as physically guiding people and preventing dangers such as falling, improper support or misdirection when people are on top of buildings and structures etc. Many demands can be met for equipment or equipment to prevent hazards in operations with limited visibility, such as underwater.

According to the present invention, in order to rotate about a common axis, a pair of rotating members are arranged at a certain distance apart, and each rotating member is spaced apart at a substantially equal distance. a pair of rotating members each having a series of protrusions disposed in an annular shape, each extending toward the other member, and arranged so as to surround a common axis of rotation with the other member; A locating member having at least a portion spaced apart, each side of the locating member having an arcuate recess for accommodating only the tips of the series of protrusions and for positioning. a locating member that is rotatable about the common axis of rotation with respect to the locating member, while the locating member is rotatable with respect to the locating member through the arcuate recess as the rotating member rotates; A device for moving loads is provided, characterized in that a rotary member is positioned by means of a sliding protrusion.

In some embodiments, the protrusion is
each for free rotation so that these act as rolling elements to facilitate movement through corresponding arcuate recesses of the locating member, which are usually provided by arcuate grooves formed on opposite sides thereof. may be provided by cylindrical elements mounted on the rotating member. Such a structure serves to reduce friction between mutually movable parts of the load moving device.

In other embodiments, the protrusions may be fixed or integrally formed with respect to the respective rotating member and are formed with generally convex star-shaped sides. The protrusion may have the shape of a biconvex lens, such as a generally biconvex lens type.

An advantage of the structure according to the invention for a device for moving loads with projections fixed relative to these combined rotating members is that a pair of projections moving along an arcuate recess can move the engaged rotating members. , the force required to pass through the device during use and to rotate it by a support member or mount that moves therethrough along a generally straight path is reduced. This is achieved by, instead of a cylindrical projection, a projection with star-shaped flanks formed by generally arcuate surfaces with a larger radius of curvature.

When used for movement along an elongate element, such as a wire, rope or rigid rod or tubular member, which is supported at spaced locations along its length by a U-shaped suspension element, The device for moving the load is engaged with the elongated element so that the elongated element generally slides into contact with the underside of the locating element in the inter-rotating space between the axis of rotation and the locating element. Stretch in a state.

When the load moving device slides along the elongated element and encounters the suspension element, the parallel limbs of the U-shaped suspension element come into contact with a portion of the respective projection of the rotating member, and thereby The rotary member thus rotates relative to the locating element and causes the parallel arms to move the load moving device on each side of the locating element in the space defined by the set of adjacent projections. Let it pass. When it is necessary to reduce the friction between the load moving device and the elongated element, the rolling element may It may be provided in the structure of the locking member.

In some embodiments of the invention, the rotating member, which may be a generally disc-shaped element, is provided in each pair of adjacent ones thereof, for application to a transverse support element, such as the U-shaped suspension element described above. It may have a recess formed in the periphery between the protrusions. Such a load moving device may also be utilized in the device described in co-owned UK Patent No. 2049592A, in which the load moving device is engaged with a mesh structure. , and a British patent application co-assigned with the present application, in which this device for moving loads is joined to a track formed by a series of transverse bodies, usually rod-like members, located at the ends thereof. It can also be used in systems such as those described in US Pat. No. 8,112,106. For further details on the configurations disclosed herein, please refer to the above specification.

Embodiments of the present invention will be described with reference to reference examples and the accompanying drawings.

With reference to FIGS. 1 and 2, the device for moving goods consists of two wheel members (11, 12) as rotating members and one location member (13).
Each wheel member 11, 12 has a disk-shaped portion 11a, 1 having a central concave portion on the outside on one side.
2a, so that each member has a relatively thick annular rim portion 11b, 12b at its periphery. The wheel members 11, 12 are mounted to rotate around a common shaft 16.

A ring-shaped series of spaced apart cylindrical pegs (pegs 18, 19) are disposed along the rim portions 11b, 12b of each member 11,12. The proximal ends of the dowels 18, 19 are connected to respective members 11, 12 provided with annular bearing elements.
It is arranged in a cylindrical recess provided in the rim portions 11b, 12b of.

In most embodiments these bearing elements are provided by needle roller bearings, but in further possible embodiments other rolling type or plain bearings can also be provided. The dowels 18, 19 can be retained in the recesses by means of retaining rings provided in their peripheral grooves, so that when the dowels 18, 19 are located in the recesses, the needle bearings contact can be made against the inner race of the

A pair of arcuate recesses 20 and 21 are formed in both side surfaces of the positioning member 13, which is located between the wheel members 11 and 12 and located at the peripheral edge thereof.
The tip portions of dowels 18 and 19 protruding from 1 and 12 are received.

In the system shown in Figures 1 and 2,
The load moving device is engaged by an elongated wire 22 which is suspended by a series of spaced U-shaped clips 23. Various methods may be used to place the wire 22 in the load moving device. In one possible arrangement, shown in FIG. 1, a wheel 80 with a recess is mounted on the common shaft 16 for free rotation. The wheel 80 has regularly spaced radially projecting projections whose tops engage the wire 22 and guide the wire 22 to the underside of the positioning member 13. Positioned against. Preferably, the radial projection gradually curves and converges towards its apex, so that in any rotational position of the wheel 80, upon engagement of the projection of the wheel 80 with the clip 23, the clip 23 The wheels 80 self-index to receive the bottom of the clip 23 so that it passes through the load moving device.

The load may be attached to the load moving device in any suitable manner, such as by using a yoke member surrounding the load moving device and rotatably mounted to an extension of the common shaft 16. can.

When the load moves, the load moving device connects the wire 22
slide along. When it hits the U-shaped clip 23, the parallel vertical arms of the clip 23 are received in the space between an adjacent pair of dowels 18,19.

As the device for moving the load slides further along the wire 22, the wheel members 11 and 12 rotate relative to the positioning member 13 in order to pass the parallel vertical arms of the clip 23 through the attachment, while the wire 2
2 itself remains in sliding contact with the positioning member 13. In this way, the support clip 23 can traverse the load transfer device without leaving the wire.

In such a construction, the friction between the mutually movable parts of the load moving device, namely the dowels 18, 19 and the positioning member 13,
19, so that the dowels 18, 19 are free to pass through the arcuate bearing raceway formed by the recesses 20 and 21 of the locating member 13. It can be rotated to

FIG. 3 shows a variant of the wheel that can be used in a load moving device of the type shown in FIG.

The wheel member 30 is similar to the wheel member 1 of FIG.
It is the same as 1 and 12.

According to this structure, a support element for the wire engaging the load moving device and extending parallel to the axis of rotation of the wheel member 30 is adapted to this cutout 31, so that when the load moving device is used, , can be moved past this support element.

Furthermore, this structure can be used in the device described in British Patent Application No. 8112106, co-owned by the present application. In the above specification, the load moving device moves along a path defined by a series of spaced apart rod or bar elements extending transverse to the direction of movement of the load moving device. These transverse rod or bar elements are received in the cutouts 31 and positioned relative to the load moving device by means of a positioning member such that the rod or bar elements are moved past the device.

Similarly, a device for moving goods of this type could be used in the system described in British Patent No. 2,049,592A, which is co-owned by the present application. Thereby, the load moving device is engaged with the mesh structure such that the load moving device moves through the mesh, and the transverse elements of such structure are accommodated in the cutouts 31 of the wheel member 30. .

The components of the load moving device may be made from any suitable material, for example metal such as stainless steel, or for lighter weight applications, plastic material.

In another embodiment of the invention, the pegs or other elements comprising a ring-shaped series of axial projections can each be fixed in a recess in the wheel member and cannot rotate there. should be obvious. In such an embodiment, the protrusion would be in sliding rather than rolling engagement within the arcuate recess in the locating member.

In the embodiment shown in the drawings, the wire 22 is
It is accommodated in a partially circular groove 32 on the underside of the positioning member 13. This groove 32, when viewed in cross-section, may extend more than half a circle to partially surround the wire 22 and retain it within the groove 32.
In such embodiments, there is no need to use wheels 80.

In this way, it is possible to twist the load in the space between the pegs 18, 19 as a pair of adjacent projections, and thereby when the wheel members 11, 12 are then rotated in relation to the positioning member 13. In the event of subsequent "winding out" of the load moving device, engagement of the wire 22 reduces the likelihood of the device becoming unwound from the wire.

The distal end section of the wire 22 can be easily engaged in the partially circular groove 32 through its longitudinal opening;
Thereafter, the load moving device may be moved along the wire 22 and a smaller diameter wire messenger may be provided within the groove 32 to engage the main large diameter portion of the wire 22.

The device for moving luggage according to the present invention can be used, for example, with a connecting member having the structure illustrated in British Patent Application No. 8112221 (indicated by the reference numeral 14) ), it extends between the two series of dowels 18 and 19,
Additionally, a cargo attachment arm may be provided, one end of which is rotatably mounted on the common shaft 16.

This load attachment arm also includes the locking member illustrated in co-owned UK patent application no. ), thereby allowing
