Description

[0001] The invention relates to a load roller device for moving a load object, comprising a base body, wherein an adjustable fixing device is attached to a fixing side of the base body and a movement device comprising a load roller is attached to a roller bearing side of the base body opposite the fixing side.

[0002] From WO 2017 / 202541 A1, a wheel assembly for moving an object is known, comprising a wheel, a body supported by the wheel, and a clamping arrangement that can be attached to the object. The clamping arrangement has a bearing surface to secure the object. When the object is secured in the clamping arrangement, it can be moved across the floor by the wheel assembly. During this process, the wheel assembly moves across the floor, and the associated wheel rolls across the floor as the object is moved.

[0003] The object of this invention is to provide a load roller device that makes it possible to transport elongated load objects into areas that are difficult to access.

[0004] According to the invention, the problem is solved by the load roller extending from the roller bearing side to a load side of the base body, wherein the load side is arranged on a side of the base body that differs from the fixing side and the roller bearing side.

[0005] The fixing device serves to securely fix the load roller assembly in place, whereby the load object is guided past the load roller assembly on the load roller. The load roller rolls on the load object. The load roller assembly can be fixed in an inaccessible area, such as a transition area between a ceiling and a wall or a duct, and the load object can be positioned in this area. The load object can be a pipe or another elongated object.

[0006] A first roller section of the load roller, located on the roller bearing side, is larger than a second roller section located on the load side. Each roller section is a spatial segment in which the load roller is positioned and performs its rotation.

[0007] Advantageously, the motion device has a bearing extension fixed to the base body on the roller bearing side, on which the load roller is rotatably mounted. The bearing extension can extend in a direction away from the base body.

[0008] A special design feature involves the fixing device having a movable clamping unit attached to the base body on the fixing side. In this case, only one component of the clamping unit and / or the entire clamping unit can be movable.

[0009] Advantageously, the clamping unit comprises a sliding block movably mounted on a guide formed on the fixing side of the base body and a clamping jaw movable relative to the sliding block. The clamping unit is designed in the manner of a screw clamp.

[0010] Preferably, the clamping jaw and the sliding block are connected to each other by a clamping device, preferably designed as a clamping screw, wherein the clamping jaw is adjustable relative to the sliding block by means of the clamping device. The clamping device can have a handle by means of which, for example, the clamping screw can be turned and thereby the clamping jaw adjusted.

[0011] Another embodiment includes a fixing device with a counter-holding jaw fixedly attached to the base body on the fixing side, wherein a clamping space, adjustable by the sliding block and / or the clamping jaw, is formed between the counter-holding jaw and the clamping jaw for arranging a preferably stationary fixing element. The fixing element can be clamped in the clamping space by the fixing device between the counter-holding jaw and the clamping jaw.

[0012] To ensure the most secure clamping of the fixing element, at least one positioning feature is formed on the clamping jaw, located on a clamping jaw surface facing into the clamping space. When fixing the load roller device, the fixing element can be positioned within this positioning feature, thus creating both a force-fit and a form-fit connection of the fixing element within the clamping space.

[0013] It is advantageous if the load roller has an axis of rotation that is oriented perpendicular to a longitudinal axis of the base body and to a longitudinal axis of the clamping jaw of the counter-holding jaw. Preferably, the longitudinal axis of the clamping jaw is oriented perpendicular to the longitudinal axis of the base body.

[0014] The fixing side can be arranged on the base body opposite the roller bearing side, with the load side extending transversely to the fixing side and transversely to the roller bearing side on the base body. Preferably, the fixing side, the roller bearing side, and the load side lie in a common imaginary plane.

[0015] Preferably, the base body, together with the counter-holding jaw, has an L-shaped longitudinal profile. The counter-holding jaw is firmly connected to the base body and extends approximately perpendicularly away from the base body.

[0016] Furthermore, the base body, together with the counter-holding jaw and the bearing extension, has a T-shaped basic form. The counter-holding jaw and the bearing extension are firmly connected to the base body and extend in opposite directions, preferably perpendicularly, away from the base body.

[0017] It is advantageous to arrange a load-slip element on the base body on the load side. The load-slip element has a sliding surface facing away from the base body. When the load is mounted, only the load roller is contacted by a surface of the load. The load roller then rolls on the surface of the load. When the load roller assembly is disassembled, the load can be supported simultaneously on the load roller and on the load-slip element on the load side. Alternatively, when the load roller assembly is disassembled, the load can be arranged to slide only on the load-slip element. The load roller assembly is disassembled after the load has been successfully positioned. Preferably, the load-slip element is arranged on a load-side surface of the counter-holding jaw located on the load side.

[0018] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations. The scope of the invention is defined solely by the claims.

[0019] The invention will be explained in more detail below using an exemplary embodiment with reference to the associated drawings.

[0020] It shows: Fig. 1. A front view of a load roller device with a movement device and a fixing device. Fig. 2 a bottom view of the load roller device, Fig. 3 a side view of the load roller device, Fig. 4 Another side view of the load roller device Fig. 5 a top view of the load roller device, Fig. 6 a wall bracket attached to a wall with a pipe arranged on it, which is movably mounted on the wall bracket by the load roller device.

[0021] In Fig. Figure 1 shows a load roller device 10 for moving a load object 12, particularly an elongated one, such as a pipe, a beam, a crossbeam, and / or a rod. The load roller device 10 allows the load object 12 to be positioned in an inaccessible area, such as the transition area between a ceiling and a wall or a duct.

[0022] The load roller device 10 has a base body 14. The base body 14 is preferably an elongated, robustly designed component of the load roller device 10. The base body 14 can have a cuboid shape.

[0023] The base body 14 has a fixing side 16 on which a fixing surface 19 of the base body 14 is arranged. A fixing device 15 is formed on the fixing side 16 and is arranged on the fixing surface 19. The fixing device 15 serves to fix the load roller device 10 in space. Here, a Fig. The fixing element 43 shown in Figure 6 is firmly connected to the load roller device 10 by the fixing device 15. The connection between the fixing device 15 and the load roller device 10 can be detachable. The fixing element 43 can, by way of example, be rigidly connected to a wall 56 or another fixed object.

[0024] A motion device 20, comprising a load roller 18, is attached to a roller side surface 21 on a roller bearing side 17 of the base body 14 opposite the fixing side 16. The base body 14 is arranged between the fixing side 16 and the roller bearing side 17, with the fixing side 16 and the roller bearing side 17 extending along the elongated fixing surface 19 and the roller side surface 21, respectively. The fixing side 16 and the roller bearing side 17 run along a longitudinal axis 48 of the base body 14, and neither the fixing side 16 nor the roller bearing side 17 project beyond the base body 14 in the direction of the longitudinal axis 48.

[0025] The load roller 18 extends from the roller bearing side 17 to a load side 22 of the base body 14, the load side 22 being located on a side of the base body 14 that differs from the fixing side 16 and the roller bearing side 17. The load side 22 borders the fixing side 16 and the roller bearing side 17 and extends substantially transversely to the longitudinal axis 48 of the base body. The load side 22 is located at one longitudinal end of the base body 14. The fixing side 16, the roller bearing side 17, and the load side 22 lie in a common imaginary plane, in which the longitudinal axis 48 of the base body is also located. The load roller 18 has an axis of rotation 47 that is oriented perpendicular to the imaginary plane. The fixing side 16, the roller bearing side 17, and the load side 22 are in the Fig. 1. The lines are shown by dash-dotted lines for illustrative purposes only. The fixing side 16, the roller bearing side 17, and the load side 22 have, in addition to the two in the plane of the drawing, Fig. 1. Schematically represented directions of extension also include one perpendicular to the plane of the drawing. Fig. 1 aligned direction of extension.

[0026] The load roller 18 projects beyond the longitudinal end of the base body 14, such that part of the load roller 18 is located on the load side 22. A first roller section of the load roller 18, located on the roller bearing side 17, is larger than a second roller section located on the load side 22. Each roller section is a spatial segment in which the load roller 18 is located. The load roller 18 rotates within its roller section. Since the boundary between the load side 22 and the roller bearing side 17 is defined as an imaginary straight line, the first and second roller sections are segment-shaped, with the axis of rotation 47 located in the first roller section. The load roller 18 is disk-shaped, with one disk plane of the load roller 18 arranged parallel to or in the imaginary plane.

[0027] The load object 12, rolling on the load roller 18, is guided past the load roller device by an assembly movement 23 oriented transversely to the longitudinal axis 48 of the object, while the load roller device 10 is fixedly attached to the fixing element 43. During this movement, the load roller 18 rotates in the direction of rotation corresponding to the direction of the assembly movement 23. The load object 12 is preferably located entirely on the load side 22 during the assembly movement 23.

[0028] Advantageously, the motion device 20 has a bearing extension fixed to the base body 14 on the roller bearing side 17, on which the load roller is rotatably mounted. The bearing extension 28 can extend approximately transversely in a direction away from the base body 14. The bearing extension 28 can be fork-shaped, consisting of two plate-like flange sections extending parallel from the roller side surface 21, between which the load roller 18 is rotatably arranged. The bearing extension 28 is attached to an end region of the roller side surface 21 facing the load side 22. The bearing extension 28 can have a longitudinal axis, which in particular forms an angle other than 90° with the longitudinal axis 48 of the body. Alternatively, the angle can be 90°.

[0029] The fixing device 15 is attached to the fixing side 16 of the base body 14 on the fixing side surface 19. A movable clamping unit 30 is part of the fixing device 15. The clamping unit 30 can have only one movable component. Alternatively or additionally, the entire clamping unit 30 can be moved.

[0030] By way of example, the clamping unit 30 has a guide 32 formed on the fixing side 16 of the base body 14. The guide 32 can, for example, be a groove-like elongated recess extending from the fixing side surface 19 into the base body, in which a guide element 31 of the clamping unit 30 is slidably mounted. In particular, a sliding block 34 can be movably mounted against the fixing side surface 19. The sliding block 34 extends from the fixing side surface 19 in an approximately perpendicular direction. A locking screw 33 is preferably arranged at an axial end of the groove-like guide 32, which secures the guide element 31 in the guide 32.

[0031] The sliding block 34 preferably has a clamping jaw 36 that is movable relative to the sliding block 34. The clamping jaw 36 can be plate-shaped, with the main plane of the plate oriented perpendicular to the fixing side surface 19. The preferred clamping jaw 36 and the sliding block 34 are connected to each other by a clamping element 38, preferably designed as a clamping screw 38, wherein the clamping jaw 36 is adjustable relative to the sliding block 34 by means of the clamping element 38. The exemplary clamping screw 38 can have a handle 39 preferably attached to one end of the clamping screw, by means of which the clamping screw 38 can be rotated. This allows the clamping jaw 36 to be adjusted relative to the sliding block 34.

[0032] The clamping device 15 has a counter-holding jaw 40 fixedly attached to the base body 14 on the clamping side 16, wherein a clamping chamber 42, adjustable by the sliding block 34 and / or the clamping jaw 36, is formed between the counter-holding jaw 40 and the clamping jaw 36. The clamping element 43 can be arranged in the clamping chamber 42. The clamping element 43 can be clamped in the clamping chamber 42 by the clamping device 15 between the counter-holding jaw 40 and the clamping jaw 36 by means of the clamping device 38. The clamping device 15 is designed in the manner of a screw clamp.

[0033] At least one positioning feature 44 is formed on the clamping jaw 36, which is arranged on a clamping jaw surface 46 facing into the clamping chamber 42. Several positioning features 44 can be arranged on the clamping jaw surface 46. For example, groove-like recesses can be provided as positioning features 44, which intersect, for example, at right angles on the clamping jaw surface 46. When clamping the fixing device 15, the fixing element 43 can be arranged in the positioning feature 44, so that, in addition to a force-fit, a form-fit locking of the fixing element 43 is created in the clamping chamber 42.

[0034] The counter-holding jaw 40 has an elongated shape, with a clamping jaw longitudinal axis 50 of the counter-holding jaw 40 oriented perpendicular to the axis of rotation 47 of the load roller 18 and to the longitudinal axis 48 of the base body 14. The assembly movement direction 23 can be oriented approximately parallel to the clamping jaw longitudinal axis 50. The longitudinal extension axis of the clamping device can be oriented perpendicular to the clamping jaw longitudinal axis 50. The counter-holding jaw 40 is attached to the end region of the base body 14 on the fixing side surface 19, where the bearing extension 28 is also located.

[0035] The base body 14 and the counter-holding jaw 40 together form an L-shaped longitudinal profile, with the two components, together with the bearing extension 28, forming a T-shaped overall basic shape. The bearing extension 28 and the counter-holding jaw 40 are arranged at approximately the same height along the longitudinal axis 48 of the body on the base body 14.

[0036] A load-sliding element 52, preferably made of polytetrafluoroethylene, is arranged on the load-side 22. It is plate-shaped and attached to the base body 14. The load-sliding element 52 has a sliding surface. This sliding surface faces away from the base body 14 and towards the load object 12. When the load object 12 is mounted, only the load roller 18 is in contact with a surface of the load object 12. The load roller 18 rolls on the surface of the load object 12. When the load roller assembly 10 is disassembled, the load object 12 can be supported simultaneously on the load roller 18 and on the load-sliding element 52 on the load-side 22. Alternatively, when the load roller assembly 10 is disassembled, the load object 12 can be mounted sliding only on the load-sliding element 52. The load roller assembly 10 is disassembled after the load object 12 has been successfully positioned.This ensures that the load object 12 is supported at two points by the load roller device 10. The load sliding element 52 is arranged on a load-side surface 54 of the counter-holding jaw 40 located on the load side 22. Furthermore, the load sliding element 52 is arranged at an end distal to the longitudinal axis 50 of the clamping jaw 40.

[0037] In Fig. Figure 2 is a bottom view of the load roller device 10. Fig. Figure 1 shows that the guide element 31 and the guide 32 have, in particular, a T-shaped cross-section with respect to the longitudinal axis 48 of the body. The locking screw 33 projects into the guide and prevents the guide element 31 from slipping out.

[0038] Fig. Figure 3 includes a side view of the fixing side 16 of the load roller device 10. Fig. 1, wherein a further positioning feature 44 is visible on the clamping jaw 36, which is in particular perpendicular to the positioning feature 44 of the Fig. 1 is aligned.

[0039] Another side view of the roller bearing side 17 of the load roller device 10 is shown in Fig. Figure 4 shows the plate-like flange parts between which the load roller 18 is rotatably mounted. The axis of rotation 47 extends through the flange parts.

[0040] In Fig. Figure 5 shows a top view of the load roller device 10. The load sliding element 52 has a preferably rectangular sliding surface.

[0041] A load object 12, for example a pipe, positioned by means of two load roller devices 10, is in Fig. Figure 6 shows a wall bracket 58 for the pipe, which is attached to the wall 56. A section of the wall bracket 58 forms the fixing element 43, which is fixed by the fixing device 15 of the load roller devices 10. The two load roller devices 10 support the pipe against their weight, so that it can perform the assembly movement 23 in a direction relative to the plane of the drawing. Fig. 6 vertical directions. The pipe can be placed on the wall bracket 58 along its axial longitudinal direction and moved on the load roller devices 10 until it is brought into the desired position.
