Description

  The invention relates to a connection device according to the claims.

  In various situations, it is necessary to connect one object or the like to one or more other objects. To meet this need, several different types of connection devices intended for use in several different applications have been developed over the years. For example, connection devices suitable for use in connecting noise-reducing components and various types of weather-resistant protective equipment (weather (climate) protection) to scaffolding materials and the like have been developed. It was. In addition, signs and signs, hardware (lighting fixtures, alarms, cameras, etc.), equipment used in entertainment settings (speakers, lamps, stage tools, etc.), and the like, and various types of pipes Connection devices have been designed for attachment to tubes, rods, profiles and the like.

  For example, one problem when connecting layers of material, such as weatherproof protective sheets, to a scaffold is that the layers of material described above (and indirectly, the building) in strong winds. It means that a high load (drag load) is generated. These types of seats are typically designed to loosen away from the scaffold when the wind speed exceeds a certain level. These types of sheets are usually made from light materials that have very little noise reduction. Therefore, the damage caused to people and objects on the ground by these layers of loosely spaced material is usually minor. The relatively heavy layer of material, such as provided in current noise reduction units, requires other techniques that do not cause serious damage to people and property on the ground that hit the noise reduction unit.

  Another problem when connecting an object to a scaffold, for example, is that the cross-sectional dimensions and shapes of the pipe and shape to which the object is to be connected vary. For example, some pipes and shapes have round and quadrilateral or various other square shapes. As a result of the various shapes of pipes, rods and shapes, a wide variety of specially designed connection devices are required.

  A further problem with known configurations of connecting devices suitable for attaching a layer of sheet material to the outside of the scaffold includes unfixed parts where the known connecting devices may fall during assembly and disassembly. That's what it means. If dropped, these parts may fall and injure a person under and / or near the scaffold. Also, these unfixed parts make the installation operator's work difficult.

Prior art It is known to use a connecting device for connecting at least one object to another object. For example, International Publication WO 2012/060759 describes the use of a connection device to connect a noise reduction unit to a scaffold or the like. The connection device in the described noise reduction system is used to connect the noise reduction unit to a pipe, bar or the like in a scaffold or other similar structure. The connection device according to the above description is different from the configuration according to the present patent application. For example, the configuration according to the above description does not include a function that allows the noise reduction unit to be released (separated) when the wind speed exceeds a predetermined intensity.

  Another problem with the configuration according to WO 2012/060759 consists of problems due to the range and shape of the pipes contained in the scaffold. As an example, it is not uncommon for the scaffold component to have, for example, a square cross section. The connection device of WO2012 / 060579 is particularly suitable for use with pipes and shapes having a circular cross section. Even if this connecting device functions sufficiently, difficulties arise when connecting the connecting device to a shaped object having a cross section other than a circular shape such as a square cross section.

  A further problem with the connecting device according to WO 2012/060759 is that under certain circumstances, this connecting device may be difficult to connect to a circular cross-section pipe in the scaffold. This problem is solved by the configuration according to this patent application.

  US Pat. No. 5,387,250 describes a variation of a connection device suitable for connecting a layer of material to a pipe in a scaffold. This configuration is a modification of the cable tie configuration. This configuration consists of a further modification of a simple modification of the trigger mechanism which is composed of a narrower part of the cable tie. This configuration is substantially different from the configuration according to this patent application. For example, a configuration according to the description is intended for single use. Furthermore, this arrangement lacks an insert that can adapt the connecting device to the shape and dimensions of the pipe or shape to which the connecting device is to be connected.

  In view of the problems described above and the known configurations, it is clear that a significantly improved connection device according to the present patent application is needed.

  The main objective of the present invention is to create an improved connection device that solves or reduces at least one of the above-mentioned problems.

  Another object of the present invention is an improvement that is included in a scaffold-like structure, such that a noise-reducing structure can be connected to pipes, rods, and shapes having various cross-sectional shapes, for example. Is to create a connected device. It is a further object of the present invention to create a noise cancellation system that is automatically and partially released from the structure (such as a scaffold) when the wind speed exceeds a predetermined level.

  The above objective is solved by a device according to the claims.

The first bracket 6, the connecting portion 5, and the bracket 14, in other embodiments, include two or more parts that are joined in a manner suitable for the purpose. In other embodiments, the control element and the locking element may have other configurations as suitable for the purpose.

  Referring to FIG. 2C, there is shown a connecting device in which the one or more brackets 6 are installed by another method. In yet another embodiment, it is conceivable that one or more brackets 6 are connected to the connection part 5 at other positions as suitable for the purpose. In still other embodiments, the bracket 6 may be constructed from any other type of known bracket (other than those illustrated here) suitable for the purpose.

  In a further variant of the invention, the first connection device 1 may be connected to the second connection device 1. It is further conceivable that the first connection part 4 is composed of a similar configuration, for example the whole or part of the connection part 5.

  Referring to FIGS. 3A-3F, how the connecting device 1 is connected to pipes, rods, tubes, shapes, etc. (eg in a scaffold) is shown schematically. In FIG. 3A, the connecting portion is in a position near the pipe and is in the open state. In FIG. 3D, the connecting portion is attached to the pipe.

  In other embodiments, the connecting portion includes a locking feature that allows the connecting device 1 to be locked in a locked position relative to the scaffold pipe. This is illustrated in FIG. 3F by the lock being used to secure at least two parts included in the connecting device.

  Referring to FIG. 4, a variation of the connection device 1 suitable for use for objects having a shape other than a circular cross section is shown. In this exemplary embodiment, the connection device is suitable for connection to an object having a square cross section. In other embodiments, the connection device is suitable for use with objects having other cross-sectional shapes, such as rectangular, triangular, square, pentagonal, hexagonal and the like. It is further conceivable that these objects have an oval cross section or other types of cross sectional shapes.

  In order to allow what has been mentioned above, the shape of the first segment 8, the second segment 9 and the third segment 10 (see FIGS. 1-3) of the connecting device 1 is, for example, It is adjusted according to the shape of the object to be clamped (attached) by the connecting device 1, such as a pipe, a rod, a tube or a shape. Preferably, the shape of the locking element 11 is also adapted to the shape of the cross section of the object to be connected to the connection device 1.

  Referring to FIG. 5, another embodiment of a connection device is shown that includes at least one insert 18, appendage or the like suitable for connection to the connection portion 5. The insert 18 covers all or part of a normal contact surface (without an insert) for a pipe, a rod, a tube, a shaped object, or the like in the connecting device. With an insert, a contact surface 19 is realized which has a different shape and / or dimensions than the connecting device has without an insert. An exemplary embodiment of the present invention comprises at least one insert 18 that surrounds a pipe or shape portion (the insert has at least one opening in one direction).

  Referring to FIGS. 6A-6D, several exemplary embodiments of insert shapes are shown. FIG. 6 shows a variation of the insert 18 having at least one first part 20 and at least one second part 21.

  In the exemplary embodiment of the insert shown in FIGS. 6A and 6B, the first portion 20 and the second portion 21 are connected to each other via at least one joint / hinge 22 or the like. In the exemplary embodiment, the joint / hinge 22 consists of a single material layer 23 that connects the first part 20 and the second part 21 and is thin compared to the first part and the second part. . This configuration provides one more functional insert and one insert whose parts are held together in one unit.

  In the exemplary embodiment, insert 18 includes at least one attachment element 24. The insert 18 or the appendage is connected to the connecting device 1 by the attachment element 24. The attachment element 24 in this exemplary embodiment is integrated into the first part 20 or the second part 21 of the connecting device. In this exemplary embodiment, the attachment element includes a tongue of material. In order to allow the attachment element 24 to be connected to the connection device 1, an opening 25, a slot, a hole or the like is provided. The opening is suitable for inserting the locking member 26 therein. By using the insert according to the invention, it is possible to adapt (adjust) the connection device to the contact surface of the object, depending on the shape of the object with which the insert is to be clamped together. A further advantage of the insert according to this embodiment is that it consists of a single piece that allows it to be fixed relative to the mounting element (so as not to lose or drop). In other embodiments, the insert may be composed of more or fewer parts, such as, for example, three or more.

  In other embodiments shown in FIGS. 6C and 6D, the first portion 20 and the second portion 21 may be composed of separate portions. These portions can be centered together using a mechanism suitable for centering purposes, such as, for example, at least one guide pin and associated hole.

  In these drawings, an embodiment of an insert suitable for use when connected to an object having an angular shape, such as the illustrated quadrangular cross section. In other embodiments, the insert may be suitable for reducing the same shape, for example to make the circle a smaller diameter. In other embodiments, the insert is constructed of or includes a resilient (spring-like) material.

  Another embodiment of the connecting device 1 has at least a function of separating (releasing) the mutually connected objects when the mutual force between the mutually connected objects exceeds a predetermined level. One release mechanism (separation mechanism) 27 and the like are included. The configuration and shape of the release mechanism 27 may vary within the scope of the present invention. The release mechanism 27 may be a quick coupling (quick coupling) or other type of trigger coupling variant that is separated when the force exceeds a predetermined level. A quick coupling (or other type of coupling or trigger device) may be connected, for example, between the connecting part and one of the objects. Several exemplary techniques for implementing this technical function and technical effect are described below with reference to FIGS. These exemplary configurations and techniques are not intended to limit the scope of the invention.

  Referring to FIG. 7, a further embodiment of the release mechanism 27 is shown. Here, the release function is realized by at least one break-pin 28. The break pin 28 connects the first connection portion 4 and the second connection portion 5. The break pin 28 is configured to be sheared when the force between the first connection portion 4 and the second connection portion 5 exceeds a predetermined value. Selecting various materials or combinations of materials to form the break pin 28 changes the force required to shear the break pin 28. In this way, the break pin 28 can be selected that is sheared with a force that is considered substantial to separate the first object from the second object.

  In another embodiment of this release mechanism, the trigger force is determined by the spring force. Several different configurations are possible, two to three of which are described in this patent application. What is common in these is that this activates the release mechanism when the spring force is less than the force between the objects.

  In the principle solution shown in FIG. 8 (this figure shows the detachment principle, not the whole connecting device), this effect is achieved by the female part 29 and the male part 30, The whole part or partly is inserted into the female part. The male portion includes at least one first locking member 31 that can be temporarily locked with the second locking member 32 of the female portion.

  In this embodiment of the release mechanism, the first locking member 31 of the male part 30 comprises at least one first recess 33 in the radial direction in which at least one spring 34 and at least one ball 35 are inserted. Is done. The female portion 29 includes at least one second locking member 32. In the exemplary embodiment, locking member 32 is comprised of at least one second recess 36 or the like. During the coupling, the male part ball 35 is inserted into the second locking member 32 in the female part 29 by spring force. The spring force acts so that the ball is inserted entirely or partially into the recess 36 of the female portion 29.

  The configuration of the release mechanism means that the locking members are connected together until the relative force exerted on the ball to compress the spring exceeds a predetermined level. In other embodiments, it is contemplated that the spring force can be adjusted by at least one adjustment device (not shown). The adjustment of the spring force may be set to be non-variable (incremental, stepwise, gradual) or may be set to be variable (stepless). Gradual adjustment of the spring force may be achieved by one or more washers or other spacers (not shown) placed at the bottom of the recess (bottom). The thickness of the one or more washers may be varied as needed. A gradual adjustment of the spring force may be achieved by replacing the spring. The variable adjustment of the spring force may be realized by an adjustment screw (not shown) that compresses the spring.

  In another variant (not shown) of the release mechanism 27 according to the embodiment shown in FIG. 9, the first recess 33, the spring 34 and the ball 35 are placed in the female part and the second recess 36 is male. Included in the part. Configurations of other embodiments include at least one first release mechanism and at least one second release mechanism.

  In a second alternative embodiment of the release mechanism 27, as shown in FIG. 9 (this figure shows the detachment principle and not the whole connecting device), the release mechanism 27 has at least one first The locking member 31 and at least one second locking member 32 are included. In this exemplary embodiment, the first locking member 31 includes a first hook 37 and the like, and the second locking member includes a second hook 38 and the like that engage each other. At least one of these hooks is spring loaded with at least one spring 34. The first locking member 31 is released from the second locking member 32 when the relative force between the hooks 37 and 38 exceeds a predetermined level.

  Referring to FIG. 10 (this figure shows the detachment principle, not the entire connection device), a ball-socket coupling 39 in which a (male) ball 40 engages a (female) socket 41 etc. A technique in which the release mechanism 27 includes a slight deformation of the above is shown. The socket 41 includes a partially elastic (elastic) material. The connection is made by a (male) ball 40 inserted in a (female) socket 41. The resilient (elastic) material causes the (female) socket 41 to engage the (male) ball 40 with a certain force. If the force between the (male) ball and the (female) socket is below a predetermined level, the connection between them remains connected. If the force between the (male) ball and the (female) socket exceeds this level, the separation of the female 41 and male 40 portions of the ball and socket coupling from each other occurs.

  In other embodiments of this configuration, the force required to move the coupling members away from each other is adjustable. This can be achieved by a (male) ball 40 having at least one first part 42 and at least one second part 43. These parts are acted upon by at least one adjusting device 44. By means of this adjusting device 44, the relative position of the part 42 and the part 43 can be adjusted (pressed away from each other). It is further envisaged that the inner dimensions of the (female) socket 41 can be adjusted by at least one adjusting device (not shown).

Application of the device-system for the use of the connection device The connection device 1 can be used in various applications where there is a need for at least one connection device 1 including a release function and / or a coordination function according to this patent application. . For example, the connection device (ie, the connection device 1) can be used to connect components included in the noise reduction system to each other or to the structure to which the system is connected. The connection device can be used in the above-described noise cancellation system or can be defined as part of the noise cancellation system described above.

  The noise cancellation system comprises at least one connecting device 1 comprising a release mechanism 27 according to the present patent application and / or at least one connecting device comprising an insert according to the present patent application. For example, the release function can be used to reduce wind loads on the scaffold during strong winds and the like. The release function is realized by at least one release mechanism. For example, this release mechanism disconnects the connection device from the noise reduction portion of the noise reduction unit or disconnects the connection device from the scaffold at a force above a predetermined level. The insert is used to adjust the shape of the contact surface of the connecting device for pipes, bars and shapes included in a scaffold-like structure.

  The connecting device may be used in a noise cancellation system 45 according to the following exemplary embodiment, but should not be limited to this embodiment.

  The noise cancellation system of this exemplary embodiment comprises at least one first noise suppression unit 46 connected to at least one structure 47. In the illustrated embodiment, the noise reduction system 45 comprises a plurality of different noise reduction units 46 connected to at least one structure 47 near the building, facility, or location where the emitted sound is to be reduced.

  Referring to FIGS. 11A and 11B, an exemplary embodiment of a noise cancellation unit (wall segment) 46 according to the present invention is shown in further detail. The shape of 46 of each noise cancellation unit can be varied within the scope of this patent application. Therefore, the illustrated embodiment is not limited to the configuration and shape of the noise cancellation unit 46. In the illustrated exemplary embodiment of the noise reduction unit 46, the outline of the noise reduction unit 46 is preferably essentially square. It is also conceivable that the noise reduction unit 46 has other shapes such as a rectangle or other shapes suitable for the purpose. Each of the noise cancellation units 46 has an inner side 47 and an outer side 48. Further, the square unit 46 includes at least one first end (first short side in the illustrated embodiment) 49 having at least one first opposite end 50 and at least one first. And at least one second end 51 having two opposite ends 52.

  Referring to FIGS. 12A and 12B, several noise cancellation units connected to the structure are shown. The structure of this exemplary embodiment consists of a scaffold.

  Referring to FIG. 13, an exemplary assembly of the noise cancellation unit 46 is shown. Each noise suppression unit includes at least one first material layer 53. Preferably, each noise cancellation unit 46 comprises at least one first material layer 53 and at least one second material layer 54. For example, the material layer 53 may be composed of a heavy metal foil that silences, or other material as a material suitable for the purpose. The first material layer 53 and the second material layer 54 are preferably noise eliminating materials. Between the first material layer 53 and the second material layer 54, at least one first noise suppression material layer 55 is disposed.

  Referring again to FIGS. 11A and 11B, it is shown that the noise cancellation material layer 55 is preferably divided into at least one first portion 56 and at least one second portion 57. Between the first portion 56 and the second portion 57, there is an intermediate portion 58 without the noise eliminating material layer 55. As shown, the noise cancellation material layer 55 includes at least one first portion 56, at least one second portion 57, at least one third portion 59, and at least one fourth portion. 60. Between the portions 56 and 57, between the portions 57 and 59, and between the portions 59 and 60, an intermediate portion 58 is placed without the noise-reducing material layer 55. Preferably, the first material layer 53 and the second material layer 54 are joined by an intermediate portion 60 at the ends 49-52. The joining of the material layers can be achieved by welding or other methods suitable for the purpose. Preferably, the noise cancellation unit further comprises at least one third material layer (not shown) placed inside the second material layer. The third material layer is composed of a metal foil that forms a moisture barrier or the like that reduces (or excludes) moisture permeation to the noise eliminating material.

  The connecting device 1 is preferably clamped, bolted (screwed) to the noise reduction unit at one of the ends 49-52 on the noise reduction unit, or other methods Connect properly. Referring to FIG. 14, the connection device 1 is shown connected to a stiffener 17. The stiffener 17 shape and dimensions may be varied within the scope of this patent application.

  Referring to FIGS. 2A and 2B, a connection device 1 is shown having a distance between the contact surface 7 of the bracket 6 and the first portion 8 of the connection portion 5. With this configuration, a specific function can be achieved by the connection device 1. With this configuration, it is possible to realize the overlap between the ends of two adjacent noise reduction units 46. According to this configuration, the end of each noise reduction unit 46 can be fixed to the end of a nearby noise reduction unit 46. This overlap is illustrated in FIG. Furthermore, this structure realizes a more reliably sealed structure. Furthermore, the risk of the end of the noise reduction unit flapping in a windy situation is reduced.

  Each noise reduction unit 46 includes at least one connection device 1, by which the noise reduction unit 46 can be connected to a structure 47 such as a scaffold. Preferably, the noise cancellation unit includes at least one connecting device at or near each end. In a preferred embodiment, at least two, preferably several, connecting devices are connected to each end 49-52 of the noise cancellation unit.

  The connecting device 1 on the first end 49 is offset from the position of the connecting device 1 on the first opposite end 50. The connecting device along the second end 51 is further offset from the position of the connecting device along the second opposite end 52. According to this configuration, when the first noise reduction unit and the second noise reduction unit are connected to the same pipe in the scaffold (or other type of structure), the first noise reduction unit on the first noise reduction unit The connecting device along the end 49 will not collide with the connecting device 1 along the opposite end 50 on the second noise reduction unit. This configuration also allows the second noise cancellation unit on the first noise reduction unit when the first noise reduction unit and the second noise reduction unit are connected to the same pipe in the scaffold (or other type of structure). It means that the connection device along the end 51 does not collide with the connection device along the second opposite end 52 on the second noise reduction unit.

  The ends 49-52 of the noise reduction unit (s) may comprise a recess (s) 61 for the ring of the scaffold or other construction components of the scaffold. Preferably, the material layers are joined together adjacent to the recess (eg, by welding or the like).

  Each noise reduction unit 46 includes at least one reinforcement / stiffener 62 that reinforces all or part of the material adjacent at least one of the ends 50-52 of the noise reduction unit (s). The stiffener / stiffener also reinforces the end and the material adjacent to the end. Preferably, each end includes at least one first reinforcement 17 and at least one second reinforcement 63. In this exemplary embodiment, the first reinforcement is placed outside the end and the second reinforcement is placed inside. The shape (shape) of the reinforcements 62 and 63 can vary greatly within the scope of the present invention. In other embodiments, it is contemplated that at least one of the plurality of reinforcements may be integrated into at least one of any of the material layers. It is further contemplated that at least one of the plurality of reinforcements is placed between the material layers.

  Preferably, the entire noise reduction unit is not separated from the scaffold by some connecting devices that do not have a release function. For example, the connecting device in the middle of the ends 49 and 52 can be non-detachable. At high wind speeds, for example, the upper connection device of the noise reduction unit is released, so that the uppermost part of the noise reduction unit is automatically folded.

  With reference to FIGS. 16A-16C, another exemplary application of the connection device is shown. FIGS. 16A and 16B show how the connecting device is used to connect at least one sign, sign 64, etc. to the pipe. For example, signs and signs can be used appropriately to convey information to the user. Since signs and signs have been known for some time, they will not be described in further detail in this patent application. In other embodiments, the sign or sign may be composed of a banner or other for information transmission object suitable for the purpose. Referring to FIG. 16C, the use of a connection device used to connect items belonging to the stage device to pipes, tubes, shapes, etc. is shown. For example, the items may be of any type, such as lamps, cameras, audio device parts, and the like.

  The above application only represents an exemplary application of the connection device. These should not be considered limiting as to the extent to which the connection device could be used.

  In the detailed description of the invention, details of construction that will be apparent to those skilled in the art may be omitted. Such obvious configuration details are included to the extent necessary to achieve proper and maximum performance of the present invention.

Even if certain preferred embodiments are described in detail, variations, modifications, and other uses within the scope of the present invention will become apparent to those skilled in the art.
All such variations, modifications, and other uses are considered to be within the scope of the following claims.
