Description

Trolley for Rail

The present invention relates to a trolley for rails, and more particularly, to a rail trolley so as to be suitable for improving user safety and reliability of the trolley.

Generally, a sloping cable is installed on the zip line (zipper line, zip wire, aerial runway or aerial rope slide), fixed only at the top and bottom, and a trolley freely installed.

The user (load) suspended in the trolley can be accelerated by gravity from the top to the bottom of the inclined cable. In use, the trolley slides along the top of the inclined cable.

Generally, the sagging of the inclined cable and proper tension of the inclined cable are necessary to control the user's acceleration. Since the inclined cable is fixed only at the top and bottom, the inclined cable is limited to a linear path without lateral deviations such as curves or bending.

The cable is used as a monorail to provide a nonlinear path that includes lateral deviations such as curves or bending. Non-linear paths can cause rails to run around obstacles or increase user enjoyment. The top part of the rail can be fixed to the framework, or suspended, for example, from a ceiling joist or tree so that the area under the rail is not obstructed for the trolley and user to pass through.

However, there are cases where the rail trolley is bound to the rail and brake is applied. Sudden deceleration can cause injury. In addition, the trolley may stop and the user may be stranded on the rail, requiring rescue. Also, a subordinate trolley may be injured by colliding with a stationary trolley.

Next will be described in detail with reference to the accompanying drawings, preferred embodiments of the present inventor rail trolley.

A trolley for a rail according to an embodiment of the present invention includes a frame, a wheel set including a first wheel and a second wheel rotatably coupled to the frame, and coupled to the frame for suspension of load during use It comprises a fastening member, the first wheel can rotate in a first plane about the first axis, the second wheel can rotate in a second plane about the second axis, the first plane And the second plane defines a line, the trolley is a first arrangement, the fastening member is arranged at a first angular displacement around the line, the trolley is a second arrangement, the fastening member is around the line It is arranged in the second angular displacement, the first angular displacement and the second angular displacement is characterized in that different.

In the course of the use of the rail assembly, a vertical force is exerted down due to the gravitational force that can be at least partially imposed on the rail through the trolley as a result of the load.

The load can cause other forces, for example due to the pitch of the load, yawing and rolling, and centripetal force against the load that can be applied to the trolley as described below. The trolley may include one or more descending, raised and horizontal portions on the rail.

The inventors of the present invention have recognized that conventional trolleys can sometimes be unexpectedly bound to the rail and brake due to an increase in the lateral force on the rail (ie, the lateral force on the line). This increased lateral force on the rail may be due to the centripetal force and vibration of the load such as the user swinging from side to side when the trolley moves round the curved portion of the rail.

Unexpected binding and thus braking usually occurs because the user swings from side to side, which may or may not be prevented.

Since the fastening member is movable between the first and second positions, the lateral force on the rail can be reduced, for example, compared to a fixed fastening member. Thereby, the possibility of binding of the trolley and braking of the rail is reduced. Thereby, the possibility of injury to the user can be reduced, and the safety of the user and reliability of the trolley can be improved.

In addition, since the lateral force on the rail can be reduced compared to a fixed fastening member, for example, the number of wheels included in the wheel set and the size of the wheels included in the wheel set can be reduced, as described in more detail below. Explain.

Also, the strength of the frame can be reduced. Thereby, the weight and cost of the trolley can be reduced. For example, a mass reduction of about 4.8 kg to about 3.7 kg (ie, about 22%) of the trolley can be achieved due to the reduced lateral force. Conversely, an increased load can be attached to the trolley.

The load acting on the rail will be described.

Typically, the load includes or is a user with a mass ranging from 30 kg to 120 kg and thus a weight ranging from 294 N to 1,177 N. In addition, centripetal forces due to cornering can be combined. 1.5 g horizontally (ie, up to 441 N to 1,766 N). Moreover, the increased vertical load due to the downswing (eg, the user swings from a slope to a vertical position) can add up to 0.6 g vertically (ie up to 176 N to 706 N) without horizontal components. The user can be attached to the fastening member, for example via a harness.

The harness may include a dorsal D-ring. For example, for attachment to a fastening member through a sling or string. Thereby, in use, the user can hang on a hang glider type (also called "superman") position (i.e., lying down or upside down). The trolley can include a handle to hold when the user tends to do so or is in the face down position.

The above trolley will be described.

The trolley is suitable for use with a rail, and is provided to be rollable thereon. Generally, the trolley is held on the rail, for example by a set of wheels, so that the trolley may not be disengaged from the rail during use.

The trolley includes a frame to which the wheel set is rotatably coupled and to which the fastening member is coupled. That is, the frame transfers the load by load to at least one of the wheels of the wheel set, for example the first wheel and the second wheel.

The wheel set is arranged to at least partially resist one, two or three forces orthogonal to each other due to, for example, weight of the load and pitching, rolling and yawing of the trolley.

According to one preferred embodiment, the wheel set allows movement of the trolley in three directions orthogonal to each other down and up along the rail, for example due to the weight of the load and the pitching, rolling and yawing of the trolley. And at least partially resist forces in two directions orthogonal to each other.

The wheel set includes three or more wheels.

The partial set of the wheel will be described.

The wheel set includes a first set of wheels including a first wheel, a second wheel and optionally a third wheel and a fourth wheel. The first set of parts of the wheel includes more than four wheels.

The first set of parts of the wheel is provided to be rollable on the upper side part of the rail, thereby transmitting the weight due to the load on the rail and at least the force due to movement of the pitching and yawing. Thereby, the pitching and yawing of the trolley relative to the rail can be resisted.

The wheel set includes a fifth wheel and, optionally, a second partial set of wheels including a sixth wheel, a seventh wheel, and an eighth wheel.

The second set of parts of the wheel includes more than four wheels.

The second set of parts of the wheel is provided to be rollable on the lower side part of the rail, thereby transmitting the weight due to the load on the rail and at least the force due to the movement of the pitching and yawing. Thereby, the pitching and yawing of the trolley relative to the rail can be resisted.

The wheel set includes a third set of wheels comprising a ninth wheel and optionally a tenth wheel. The third set of parts of the wheel comprises two or more wheels.

The third set of parts of the wheel is provided to be rollable on the side part of the rail, thereby transmitting at least partly the force due to the movement of the load acting on the rail, for example the force due to rolling. Thereby, the rolling of the trolley relative to the rail can be resisted.

That is, the second part set of the wheel and the third part set of the wheel improve stability in use, and thus may be referred to as a stability wheel.

The wheels included in the second part set of the wheel and the third part set of the wheel are relatively smaller or lighter than the wheels included in the first part set of the wheel. In particular, since the lateral force on the rail can be reduced compared to a fixed fastening member, for example, the size and weight of these wheels included in the second set of parts of the wheel and the third set of parts of the wheel can be reduced.

In use, one or more wheels of a set of wheel parts comprising the first wheel and the second wheel generally contact the rail. In use, one or more or all of the wheels of the subset and wheel subset are generally in contact with the rail and spaced by a gap in the range of 1 mm to 10 mm, preferably in the range of 3 mm to 7 mm, but yaw of the trolley , Can contact the rail during pitching and rolling.

The wheel direction will be described.

The first wheel is rotatable in a first plane about a first axis, the second wheel is rotatable in a second plane about a second axis, and the first plane and the second plane define the line .

The first axis and the second axis are coaxial, whereby the first plane and the second plane are coplanar or parallel. When the first plane and the second plane are the same plane, the line is defined in the first plane and the second plane. If the first plane and the second plane are parallel, the line is defined between the first plane and the second plane, eg, equidistant. The first axis and the second axis are inclined to each other, and the first plane and the second plane are inclined to each other. When the first plane and the second plane form an inclined surface with each other, the line is defined by the intersection of the first plane and the second plane.

The line is the intersection of the first plane and the second plane. According to a preferred embodiment, the line is the intersection of the first plane and the second plane, the rail comprises a cylindrical running surface defining the cylinder axis, the line substantially coinciding with the cylinder axis in use.

The line, as a percentage of the radius of the cylindrical running surface, is substantially within 20% of the cylinder axis, preferably within 15%, more preferably within 10%, and most preferably within 5% of the cylinder axis. Matches.

The first and second axes abut a radius perpendicular to the line.

The wheel will be described.

The first wheel comprises a tire formed of a polymer composition, for example a thermoplastic material such as polyurethane or nylon, having one or more bearings, for example ball bearings.

The bearing is sealed (ie, has a seal, also known as a shield or closure), reducing maintenance requirements or improving safety.

The first wheel (eg, tire) has an outer diameter in the range of 40 mm to 80 mm, preferably 50 mm to 70 mm. The smaller wheels provide greater stability and accelerate faster, while the larger wheels are smoother and suitable for higher speeds on rough surfaces.

The first wheel (eg, tire) has a hardness in the range of 70 to 110a (determined using a durometer). Soft wheels (eg 70a) have good grip and hard wheels (eg 100a) are fast. The first wheel is a flat wheel (ie, having a cylindrical rolling surface), thereby having a relatively large contact patch (ie, surface area). The first wheel has a range of 5 mm to 40 mm, preferably 10 mm to 30 mm.

The first wheel is mounted on a rotating shaft, and the rotating shaft is fixed to a frame.

The first wheel includes an adjustable first wheel. Thereby, the spacing of the first wheel in the rail can be adjusted in consideration of the wear of the first wheel and the rail,

Preload is applied to the first wheel, for example to control pitching, rolling or yawing of the trolley. The rotating shaft comprises an eccentric rotating shaft, whereby the first wheel comprises an adjustable first wheel.

The first wheel is a manual wheel (ie, not driven). The first wheel is the active wheel (ie, driven). The trolley comprises an actuator provided to drive the first wheel, for example an electric motor and optionally a power and power controller.

The second wheel can be as described for the first wheel. Each wheel in the subset of wheels may be as described for the first wheel. The wheel is a wheel included in the partial set of the second wheel and the third partial set. The wheel is relatively small or lighter than the wheels included in the first set of parts of the wheel.

The wheels included in the second part set of the wheel and the third part set of the wheel have a width of 5 mm to 30 mm, preferably 10 mm to 20 mm.

The fastening member will be described.

The trolley comprises a fastening member coupled to the frame for fastening of the load during use, preferably for suspension (suspension). Thereby, the load is fastened from the frame, and preferably can be suspended (suspension).

The fastening member is releasably coupled to the frame. A tool must be used to release the fastening member from the frame. According to this, inadvertent or intentional release of the fastening member during use can be prevented, and safety can be improved. The fastening member can be released from the frame using a fastener, for example, a pin fastener, a split pin (also referred to as a coater pin, coater key or split coater), a locking ring, and a mouse. Thereby, inadvertent or intentional release of the fastening member during use can be prevented, thereby improving safety. The fastening member generally includes a U-shaped piece of metal fixed across its opening with a clevis pin or bolt or a shackle (clasp) that is a hinged metal loop secured with a quick-release.

The clasp is a bow clasp, D shackle, headboard clasp, pin clasp, snap clasp, threaded clasp or twist clasp. A pin clasp closed with an anchor bolt and a split pin and comprising a fixing nut in addition to the split pin is preferred. This is because careless or intentional release of the fastening member during use can be prevented. Mouse thread clasps are also suitable. Quick release shackles, such as snap shackles or carabiners, can be easily released during use with one hand and are generally undesirable.

The arrangement of the trolley will be described.

The trolley can be arranged as follows.

In a first arrangement, the fastening member is disposed at the first angular displacement around the line, and in a second arrangement, the fastening member is disposed at a second angular displacement around the line, the first angular displacement and the first 2 The angular displacement is different.

As described above, since the fastening member is movable between the first and second positions, the lateral force on the rail can be reduced, for example, compared to a fixed fastening member. Thereby, the possibility of trolley binding and rail braking is reduced. Thereby, the possibility of injury to the user can be reduced. In addition, the user's safety and the reliability of the trolley can be improved.

The height of the fastening member at the second angular displacement is greater than the height at the first angular displacement. That is, the second gravitational potential energy of the load when the trolley is arranged in the second arrangement is greater than the first gravitational potential energy of the load when the trolley is arranged in the first arrangement. That is, the work must be done to move the fastening member from the first arrangement to the second arrangement. Thereby, the movement of the load and thus the fastening member traversing the line can be adjusted, for example.

The trolley is arranged to move from the first arrangement to the second arrangement due to lateral forces (ie, lateral forces) to the line, at least partially due to movement of the load across the line.

For example, when the trolley moves around the bent portion of the rail, the load may move transversely to the line due to centripetal force. For example, the load may move across the line due to vibrations of the load, such as the user swinging from side to side (ie rolling the trolley).

The fastening member is arranged to move from the first angular displacement to the second angular displacement relative to the line, for example in an arc of increasing height. Thereby, the movement of the fastening member is smooth, and can improve the user experience and safety, but the operation for moving the fastening member from the first arrangement to the second arrangement must be performed as described above. According to one preferred embodiment, the rail comprises a cylindrical running surface defining a cylinder axis, the line substantially coinciding with the cylinder axis in use, and the fastening member is removed from the first angular displacement in an arc to the line. It is arranged to move in two angular displacements, where the arc is concentric with the cylindrical running surface.

The trolley includes a mechanical connection to the frame, and the fastening member is connected to the mechanical connection. The mechanical connection comprises four connecting portions on a plane, for example a flat quadrilateral connection. Thereby, the fastening member can be arranged to move from the first angular displacement to the second angular displacement around the line, for example in a circular arc of increasing height or height.

The fastening member is arranged to rotate about the line, whereby in the first arrangement, the fastening member is arranged in a first angular displacement rotation about the line, and in the second arrangement, the fastening member is around the line Is arranged in a second angular displacement rotation, wherein the first angular displacement rotation and the second angular displacement rotation are different.

Describe the guide.

The trolley includes a guide coupled to the frame and is arranged to guide the fastening member between the first and second arrangements. Thereby, the movement of the fastening member can be guided, for example, controlled, restricted and limited.

The guide includes an arcuate portion. Thereby, the fastening member may be arranged to move from the first angular displacement to the second angular displacement with respect to the line, for example in a circular arc of increasing height or height.

The arcs range from 15 ° to 270 °, preferably from 45 ° to 180 °, more preferably from 60 ° to 120 °, for example an angular displacement of about 90 ° or about 100. The guide has a circular cross section, whereby the guide comprises a round bar or a round tube. The guide has a diameter in the range of 5 mm to 50 mm, preferably in the range of 10 mm to 20 mm. The round bar can be easily formed to include, for example, an arcuate portion. The guide is a material with a hardness in the range of 50 HRB to 100 HRB (100 kg of 1/16 ”ball (Rockwell B), a yield strength in the range of 150 MPa to 400 MPa, elongation in the range of 15% to 10% to 80%, Elastic modulus in the range of 150 to 400 GPa and Charpy impact (EN 10045-1) resistance in the range of 100 J to 500 J are preferred. Stainless steel SAE types 304 and 316 (preferably) are suitable.

The fastening member includes a clasp (shackle), and the clasp is arranged to slide on the guide. The guide may include a plain bearing.

The roller will be described.

The fastening member includes a roller arranged to roll the guide. Thereby, the trolley is arranged to move from the first arrangement to the second arrangement in a circular arc, for example, by rolling of the fastening member on the guide. Thereby, the movement resistance of the fastening member due to friction between the fastening member and the guide can be reduced. Thereby, the wear of the guide and the fastening member can be reduced compared to sliding of the fastening member, thereby reducing maintenance requirements and improving safety.

The fastening member comprises one or more bearings, for example a ball bearing, and a roller is mounted thereon. Thereby, the movement resistance of the fastening member due to friction between the fastening member and the guide can be further reduced. The bearing reduces sealing requirements and improves safety sealing by sealing (ie, having a seal, also known as sealing or closing).

The fastening member comprises at least one spacer, eg a washer, arranged next to the bearing, for example to space the bearing from the leg of the clasp.

The roller is a roller having a groove having a circumferential groove, for example, a circumferential radius groove. The roller has a maximum outer diameter in the range of 20 mm to 50 mm, preferably 30 mm to 40 mm. The roller is a grooved roller having a circumferential radius groove, and the guide has a circular cross section. The radius of the groove corresponds to the radius of the guide. The radius of the groove is at least the radius of the guide. The radius of the groove is larger than the radius of the guide, for example in the range of 1% to 20%, preferably in the range of 3% to 10%. Thereby, the fastening member is rotatable about the perpendicularity of the line while maintaining a sufficiently large contact area between the roller and the guide while reducing the contact stress thereon.

According to a preferred embodiment, the fastening member is closed with an anchor bolt and a split pin, and includes a grooved roller having a pin clasp and a circumferential radius groove including a fixing nut in addition to the split pin, and the grooved roller Is comprised of two ball bearings mounted on anchor bolts between the legs of the clasp spaced by two spacers.

The fastening member is, for example, the radius of the groove greater than the radius of the guide, or is rotatable relative to the normal of the line provided by a swivel, such as a swivel clasp. Other means of providing this rotation are known. Thereby, torsion of the load on the trolley can be accommodated.

The rollers have a hardness in the range of 50 HRB to 100 HRB (100 kg of 1/16 ”ball (Rockwell B), a material having a yield strength in the range of 150 MPa to 600 MPa, a breaking elongation in the range of 10% to 80%, 150 to Modulus of elasticity in the range of 600 GPa, Charpy impact in the range of 100 J to 500 J (EN 10045-1) and 30 fatigue limit in the range of 100 MPa to 500 MPa, preferably 200 MPa to 400 MPa It has been found that due to the relatively small contact area between the guides, repeated rolling of the rollers on the guides and relatively high contact stress can lead to roller breakage, for example cracking.

It is understood that repeated rolling combined with relatively high contact stress results in fatigue cracking and growth. Corrosion resistance is desirable. Stainless steel SAE types 304 and 316 (recommended) are suitable. The roller can be coated or polished, for example, to improve fatigue resistance.

A plurality of fastening members and guides will be described.

The trolley includes a plurality of fastening members and guides, for example the corresponding plurality of guides described above, each fastening member and guide. The trolley includes two fastening members and two guides.

According to a second aspect of the invention, a rail assembly comprising a rail and a trolley according to the first aspect is provided.

As described above, it is to be understood that the rails are generally inclined, but may include one or more of a descending portion, a raised portion and a horizontal portion. The rail includes a descending portion, a raised portion and a horizontal portion.

The rail comprises a non-linear, eg curved portion. Thereby, the non-linear portion allows the rail to bend around obstacles or increase user enjoyment, as described above. It should be understood that the rails can be bent sideways or up or down, but the nonlinear parts are generally sideways.

The rail comprises two or more rails, for example two parallel rails. The rail is a monorail (ie single rail). Monorails that reduce cost and weight are preferred, and can be easily fixed to a framework or suspended from a ceiling joist or tree, for example, or can be formed into a relatively complex shape comprising multiple non-linear and linear portions. It can also be up, down and horizontal.

The rails include, for example, square or rectangular rods or hollow sections and planar (ie flat) running surfaces provided by the same or unequal angular displacement sections. The rail comprises a non-planar, for example convex or concave running surface. The rail includes a cylindrical (ie convex) running surface that defines the cylinder axis.

Wherein the line, in use, substantially coincides with a cylinder axis provided by a tube (i.e., section) having a circular cross section, or part thereof, such as a U-shaped channel. Hollow sections are preferred, because the weight of the rails is reduced.

The tube has an outer diameter in the range of 40 mm to 100 mm, preferably in the range of 50 mm to 75 mm, and in the range of 1 mm to 6 mm, preferably in the range of 2 mm to 5 mm, for example 3 mm or 4 mm. Have

The rail includes a longitudinal flange (i.e. fixing means). Thereby, the rails can be fixed to the framework, or suspended, for example, from ceiling joists or trees so that the area under the rails can pass through (without disturbing) the trolley and the user. The longitudinal flange extends continuously along the length of the rail. The longitudinal flange includes one or more perforations or brackets for fixing. Other fixing means are known. The flange is welded to the section, for example continuously or intermittently.

The rails are formed of steel according to EN 10025: Part 2: 2004 grades S185, S235, S275, S355 or equivalent. The rails are coated, for example painted and galvanized, to improve corrosion resistance.

The rails are provided end-to-end, for example in a field-joined length.

According to a preferred embodiment, the rail comprises a cylindrical running surface defining a cylinder axis, the line being substantially coincident with the cylinder axis in use, for example provided by a tube having a circular cross section, the rail The silver comprises a longitudinal flange perpendicular to the tube that extends continuously along the tube (ie, upright from it).

According to a third aspect of the present invention, there is provided a kit of parts for a rail assembly comprising a rail and a trolley according to the first aspect of the present invention.
