Description

Technical Field

[0001] The present invention relates to a support assembly used when detachably attaching an auxiliary device such as a GPS receiver to a support area, particularly a roof area, of a construction machine, such as a self-propelled soil compactor.

Background Art

[0002] Auxiliary devices such as GPS receivers are often attached to roof areas such as the operator's cab of construction machines in order to ensure good reception of radio signals and protect them from damage. In order to attach such an auxiliary device later, or to remove it from the roof area for repair or maintenance work or for anti-theft purposes, it is generally necessary to access the roof area using a ladder and release screw connections etc. to remove the auxiliary device from the roof area.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The problem of the present invention is to provide a support assembly for detachably attaching an auxiliary device, particularly a GPS receiver, to a support area such as the roof area of a construction machine, and using the support assembly to make the process of attaching and detaching the auxiliary device in the roof area reliable and easy to perform while securely connecting the auxiliary device.

Means for Solving the Problems

[0004] According to the present invention, this problem is solved by a support assembly for detachably attaching an auxiliary device, particularly a GPS receiver, to a support area, particularly a roof area, of a construction machine, the support assembly comprising: - a first support part to be fixedly attached to the support area of the construction machine; - a second support part supported on the first support part so as to be pivotable around a pivot axis and slidable in a sliding direction for movement between an auxiliary device operating position and an auxiliary device attachment position; - A connecting part on the support body of the second support part for detachably connecting the auxiliary device to the second support part, Includes.

[0005] In the support assembly according to the present invention, the cooperation of two support components creates the possibility of protecting the auxiliary device supported by the second support component from unauthorized removal in a stable, fixed state when the second support component is in the auxiliary device operating position. Access to the auxiliary device is possible by moving the second support component to the auxiliary device mounting position, and the auxiliary device can be easily removed from or attached to the second support component.

[0006] In order to facilitate the movement of the second support component between the auxiliary device operating position and the auxiliary device mounting position, it has been proposed that the second support component is connected to the first support component by a pivot-sliding connection so as to be pivotable around a pivot axis and slidable in the sliding direction, and this pivot-sliding connection is - Two sliding rails are arranged on the first support component, spaced apart from each other and approximately perpendicular to the sliding direction, - A rail engagement mechanism, disposed on each sliding rail on the second support component, which is slidable in the sliding direction along the disposed sliding rail, Includes.

[0007] In this case, for the interaction that enables the necessary relative motion between the two support components, each sliding rail may have an elongated sliding opening in the sliding direction between the two support components, and each rail engagement mechanism may include a sliding projection that engages with the sliding opening of the arranged sliding rail and is slidable in the sliding direction along the sliding opening.

[0008] To obtain the pivotability necessary for transitioning between the auxiliary device operating position and the auxiliary device mounting position, each sliding projection may be pivotable around a pivot axis within the provided sliding opening.

[0009] In an alternative configuration where, due to structural constraints, the rail engagement mechanism is only slidable along the rail and cannot rotate or pivot relative to the rail, the support body of the second support component may be pivotable around a pivot axis relative to each rail engagement mechanism in order to obtain the necessary pivoting capability.

[0010] To protect the two support components from unintended movement relative to each other, it is proposed to provide a locking device that fixes the second support component so that it does not rotate or slide relative to the first support component in the auxiliary device operating position.

[0011] The locking device is, for example, - One of the first support component and the second support component, preferably the first support component, has at least one locking recess. -A locking mechanism disposed in each locking recess of the other of the first and second support components, preferably the second support component, which is capable of applying pretension to the locked position and moving from the locked position to the unlocked position against the pretension, It is possible to include, When the second support component is in the auxiliary device operating position and the locking mechanism is in the locked position, the locking mechanism is blocked from moving out of the locking recess, and when the second support component is in the auxiliary device operating position and the locking mechanism is in the unlocked position, the locking mechanism is released for movement out of the locking recess.

[0012] To obtain a stable lock interaction, -Each locking recess comprises a locking recess entrance region having a first lateral dimension of the locking recess, and a locking recess receiving region adjacent to the locking recess entrance region having a second lateral dimension of the locking recess, wherein the second lateral dimension of the locking recess is larger than the first lateral dimension of the locking recess. -Each locking mechanism comprises a locking portion having a first lateral dimension of the locking mechanism, and a locking release portion having a second lateral dimension of the locking mechanism, wherein the lateral dimension of the second locking mechanism is smaller than the lateral dimension of the first locking recess, and the lateral dimension of the first locking mechanism is larger than the lateral dimension of the first locking recess and smaller than the lateral dimension of the second locking recess. -When the second support component is in the auxiliary device operating position, each locking mechanism is positioned in the unlocked position so that the locking mechanism unlocking portion can pass through the locking recess entrance area. -When the second support component is in the auxiliary device operating position, each locking mechanism is aligned with the provided locking recess so that the locking portion of the locking mechanism is located within the locking recess receiving area. This is proposed.

[0013] Furthermore, for stable locking interaction, each sliding rail may be provided with a locking recess that is spaced apart from the sliding opening in the sliding direction and opens substantially laterally with respect to the sliding direction, and the second support component may be provided with a locking rod that provides a locking mechanism disposed in the locking recess on the sliding rail.

[0014] The locking rod may be slidable approximately laterally with respect to the sliding direction in order to move between the locked position and the unlocked position.

[0015] To securely and detachably connect the auxiliary device to the second support component, it is proposed that the connecting component includes a first connecting portion on the second support component and a second connecting portion on the auxiliary device that is connectable and engageable with the first connecting portion, and that one of the connecting portions, preferably the second connecting portion, includes a block / release mechanism that blocks one connecting portion from being disconnected from the other connecting portion and releases one connecting portion to be disconnected from the other connecting portion.

[0016] The stable connection of the auxiliary devices can be further supported by the first connection forming portion including two connection mechanisms, preferably spaced apart from each other in the sliding direction, and the second connection forming portion including at least one mating connection mechanism disposed on each connection mechanism, which is capable of engaging and disengaging with the connection mechanism.

[0017] To enable easy establishment or disengagement of the connected state, one of the mating connecting mechanisms may be pivotably supported on the provided connecting mechanism for connecting the auxiliary device to the second support component and for disconnecting the auxiliary device from the second support component, and the block / release mechanism may cooperate with the other connecting mechanism to block the disconnection of one connecting forming portion from the other connecting forming portion.

[0018] For example, in order to prevent the auxiliary device from being unintentionally disengaged from the second support component in the event of vibration, if the auxiliary device is connected to the second support component and the second support component is in the auxiliary device operating position, the block / release mechanism may be blocked from movement to release one of the connecting forming components in order to disengage from the other connecting forming component.

[0019] To ensure that this blocking action occurs only when actually necessary, i.e., when the second support component is in the auxiliary device operating position together with the auxiliary device supported by the second support component, it is proposed to provide the first support component with a first blocking mechanism that blocks the movement of the blocking / releasing mechanism.

[0020] The present invention further relates to a construction machine, particularly a soil compactor, which includes a support area, preferably a roof area disposed on a driver's cab, and a support assembly having the structure according to the present invention in the support area.

[0021] To enable easy access to the auxiliary device or support assembly, the support area may be a roof area and may include a roof hatch that can be closed by a closing flap and is adjacent to the first support part in the sliding direction. Thus, when the second support part is in the auxiliary device operating position, the second support part is in a position where it does not cover the roof hatch, and when the second support part is in the auxiliary device mounting position, the second support part is in a position where it partially covers the roof hatch.

[0022] To further protect the auxiliary device from prohibited operations, it may be specified that the closing flap is movable between a closed position for closing the roof hatch and an open position for opening the roof hatch, and that when the closing flap is in the closed position and the second support part is in the auxiliary device operating position, the second support part is blocked by the closing flap from moving to the auxiliary device mounting position.

[0023] For this purpose, the closing flap may be provided with a second blocking mechanism, and when the closing flap is in the closed position and the second support part is in the auxiliary device operating position, the second support part is blocked from pivoting by the second blocking mechanism.

[0024] The auxiliary device can include, for example, a GPS receiver. In this context, it is pointed out that such a GPS receiver in the present invention is a device configured to communicate via a satellite-based or terrestrial communication system and is set to receive corresponding signals for that purpose.

[0025] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. The drawings show the following.

[Figure 10] This is a longitudinal cross-sectional view corresponding to Figure 9, showing the auxiliary device connected to the second support component when the second support component is rotated relative to the first support component. [Figure 11] This figure corresponds to Figure 10, showing the auxiliary device connected to the second support component when the second support component rotates and slides relative to the first support component to the auxiliary device mounting position. [Figure 12] This figure shows the second support component along with the auxiliary device connected to it, as viewed through the roof hatch from direction XII in Figure 11. [Modes for carrying out the invention]

[0027] Figure 1 shows a side view of a construction machine 10 configured as a soil compactor. The construction machine 10 includes a drive wheel 14 and a driver's cab 16 at the rear of the vehicle 12, which are driven by a drive unit. A compaction roller 20 is supported at the front of the vehicle 18, which is swivelably connected to the rear of the vehicle 12 for steering the construction machine 10, so as to be rotatable around a roller rotation axis. The ground 22 is compacted by the construction machine 10 or soil compactor moving over the ground 22, such as asphalt material.

[0028] In the roof area 24 of the driver's cab 16, an auxiliary device 28, configured as, for example, a GPS receiver, is supported by a support assembly 26 so that it can be removed from or attached to the roof area 24 in a manner described later.

[0029] Figures 2 and 3 show the roof area 24 of the driver's cab 16 and an auxiliary device 28 supported on the roof area 24. The roof area 24 is provided with a roof hatch 30, which can be closed by a closing flap 32, as shown in Figure 2, directly adjacent to the auxiliary device 28 or a support assembly 26 attached to the roof area 24. For example, the roof hatch 30 can be opened by rotating or sliding the closing flap 32.

[0030] A support assembly 26 provided for detachably attaching an auxiliary device 28 to the roof area 24 includes a first support component 34 fixed to the roof area 24 by means of, for example, screw connections, welding, etc. The first support component 34 includes a support body 36 formed, for example, as a sheet metal molded part, the peripheral regions on both sides thereof bent to form two sliding rails 38, 40. The two sliding rails 38, 40 each provide a swivel-sliding connection denoted collectively by reference numeral 42, thereby connecting the first support component 34 to a second support component 44, which can be seen, for example in Figure 5, so as to be slidable in the sliding direction V and swiveling around a swivel axis S.

[0031] Each sliding rail 38, 40 has an elongated sliding opening 46 formed in the sliding direction V. A sliding rod 50 is fixed to the plate-shaped support body 48 of the second support component 44, extending almost horizontally, that is, almost perpendicularly, to the sliding direction V. The sliding rod 50 has both ends that are positioned in each sliding rail 38, 40, or in the sliding openings 46 provided in each sliding rail 38, 40, respectively, and supplies rail engagement mechanisms 52, 54 in the form of sliding protrusions that engage with the sliding openings 46. Each rail engagement mechanism 52, 54 is capable of sliding back and forth in the sliding direction V within the sliding opening 46 in which it is positioned. Simultaneously, each rail engagement mechanism 52, 54 is rotatable around the pivot axis S within the provided sliding opening 46, and therefore, in principle, at any sliding position of the second support component 44 relative to the first support component 34, the second support component 44 is rotatable relative to the first support component 44 around the pivot axis S.

[0032] The bent peripheral region 56 of the support body 36 of the first support component 34, which extends between the two sliding rails 38 and 40, may be provided with at least one elastic stopper 58 made of, for example, rubber material, and the second support component 44 will come into contact with the elastic stopper 58 when the second support component 44 is in the auxiliary device operating position, for example, by the sliding rod 50.

[0033] A locking device, collectively denoted by reference numeral 60, is provided to lock the second support component 44 so that it cannot move relative to the first support component 34 in the auxiliary device operating position, for example, as can be seen in Figures 4 and 8. The locking device includes locking recesses 62 in each guide rail 38, 40 of the first support component 34, spaced apart from each sliding opening 46 in the sliding direction V. The locking recesses 62 open approximately lateral to the sliding direction V, away from the support body 36 of the first support component 34, and therefore extend approximately lateral to or approximately perpendicular to the sliding direction V or the respective sliding openings 46.

[0034] Each locking recess 62 includes a locking recess inlet region 64, through which the locking recess 62 is opened, and each locking recess 62 includes a locking recess receiving region 66, in which each locking mechanism 68, 70 is received when the second support component 44 is in the auxiliary device operating position and the locked state is established. Each of the two locking mechanisms 68, 70 provided in each locking recess 62 is formed on a locking rod 71 that is slidably supported on the support body 48 of the second support component 44 in the locking direction R, substantially laterally or substantially perpendicular to the sliding direction V, and includes a locking mechanism locking portion 72 and a locking mechanism unlocking portion 74 adjacent to the locking mechanism locking portion 72.

[0035] Figures 10 and 11 show that in each locking recess 62, the locking recess entrance region 64 has the first locking recess lateral dimension, i.e., a dimension in the sliding direction V that is approximately lateral to the locking direction R, and this dimension is smaller than the second locking recess lateral dimension in the region of each locking recess receiving region 66.

[0036] Figure 6 shows that in each locking mechanism 68, 70, the locking portion 72 of each locking mechanism has a first lateral dimension of the locking mechanism, particularly its diameter, that is larger than the second lateral dimension of the locking mechanism in the locking release portion 74 of each locking mechanism. Furthermore, since the second lateral dimension of the locking mechanism is smaller than the lateral dimension of the first locking recess, the locking rod 71 can pass through the locking recess entrance region 64 of the locking recess 62 provided in the locking release portion 74 of the two locking mechanisms 68, 70 when it is in the unlocked position in the locking direction R.

[0037] When the second support component 44 is in the auxiliary device operating position and the lock rod 71 is in the locked position in the locking direction R, the locking mechanism lock portion 72 is located in the provided locking recess receiving region 66, and since the lateral dimension of the first locking mechanism is larger than the lateral dimension of the first locking recess, the second support component 44 cannot move out of the locking recess 62 by pivoting around its pivot axis S.

[0038] To achieve this, first, the lock rod 71 must slide from the locked position to the unlocked position in the locking direction R, against the pretensioning action of the pretension spring 76, so that each lock mechanism release part 64 aligns with the lock recess 62 in the locking direction R relative to the support body 48 of the second support part 44. This essentially makes it possible to move the lock rod 71 out of the lock recess 62 or to rotate the second support part 44 to the position shown in Figure 10. In this position, the end region of the support body 48 of the second support part 44, which also supports the lock rod 71, is rotated upward, away from the first support part 44.

[0039] Furthermore, when the second support component 44 is in the auxiliary device mounting position, at least one elastic stopper 58 pre-tensions the second support component 44 in the sliding direction V relative to the first support component 34 toward the roof hatch 30. As a result, the lock rod 71, together with the lock mechanism lock portion 72 of the lock mechanisms 68 and 70, is pre-tensioned relative to the sliding rails 38 and 40 in the portion surrounding its lock recess receiving region 66. This prevents rattling noise caused by the basically unavoidable movement of the lock mechanism lock portion 72 within the lock recess receiving region 66.

[0040] From this position, starting from the auxiliary device operating position shown in Figure 9, the second support component 44, together with the auxiliary device 28 connected to the second support component 44, can be slid toward the roof hatch 30 toward the auxiliary device mounting position in the sliding direction V. In the auxiliary device operating position, or the upward-rotated position shown in Figure 10, the auxiliary device 28 or the second support component 44 slides away from the area of ​​the roof hatch 30 and therefore does not cover the roof hatch 30. On the other hand, in the auxiliary device mounting position shown in Figure 11, the second support component 44 or the auxiliary device 28 is positioned to partially cover the roof hatch 30, thereby providing access to the opening 78 formed in the support body 48 of the second support component 44.

[0041] A connecting component, collectively denoted by reference numeral 80, is provided to detachably connect the auxiliary device 28 to the second support component 44. The connecting component 80 includes a first connecting portion 82 on the second support component 44, comprising two connecting mechanisms 84, 86, for example, rod-like, and extending substantially laterally with respect to the sliding direction V, spaced apart from each other in the sliding direction V. Displaced on the first connecting portion 82, the auxiliary device 28 is provided with a second connecting portion 88. The second connecting portion 88 includes a mating connecting mechanism 90 disposed on the connecting mechanism 84 of the first connecting portion 28, comprising a downward-facing connecting recess 92 that opens toward the second support component.

[0042] The second connecting portion 88 is disposed on the other connecting mechanism 86 of the first connecting portion 80 and includes, for example, two hook-shaped mating connecting mechanisms 94 that are spaced apart from each other and positioned laterally with respect to the sliding direction V. Each mating connecting mechanism 94 has a connecting recess 96, which opens mainly in the sliding direction V, away from the other mating connecting mechanism 90, when the second support part 44 is not pivoted relative to the first support part 34.

[0043] In the case of a coupling mechanism 86 that is received in a coupling recess 96 of the mating coupling mechanism 94, the auxiliary device 28 is basically rotatable around an axis approximately parallel to the pivot axis S relative to the second support component 44. In the case of an auxiliary device 28 connected to the second support component 44, the coupling mechanism 84 is also received in a coupling recess 92 of the mating coupling mechanism 90 that is provided therewith. For example, if the coupling mechanism 84 is received in the coupling recess 92 by a block / release mechanism 98 that is rotatably supported by the mating coupling mechanism 90, the auxiliary device 28 is connected to the two coupling mechanisms 84 and 86, and by extension to the second support component 44, and is blocked from being released by the block / release mechanism 98. For example, by rotating the block / release mechanism 98 clockwise from the block position to the release position shown in Figure 10 against the restoring force of the pretension spring, the coupling mechanism 84 is released, the mating coupling mechanism 90 moves away from the coupling mechanism 84, and the auxiliary device 28 is able to rotate around the coupling mechanism 86 accordingly. After sufficient rotation, the auxiliary device 28 can be pulled away from the coupling mechanism 86, thereby disengaging from the coupling recess 96 and releasing the connection with the second support component 44.

[0044] To remove the auxiliary device 28 from the second support component 44 or the roof area 24, for example, the connecting cable 100 that passes through the opening 78 of the support body 48 of the second support component 44 can be removed from, for example, a connecting plug provided in the roof area 24.

[0045] In Figure 8, the support body 36 of the first support component 34 is provided with a first block mechanism 102, which is formed, for example, by bending. It can be seen that when the second support component 44 is in the auxiliary device operating position, the block / release mechanism 98 is blocked from rotating and releasing the coupling mechanism 84 by the first block mechanism 102. Furthermore, when the second support component 44 is in the auxiliary device operating position and the roof hatch 30 is closed by the closing flap 32, the second block mechanism 104 provided on the closing flap 32 is positioned to partially cover the second support component 44.

[0046] With the second support component 44 in the auxiliary device operating position, the closing flap 32 in the position to close the roof hatch 30, and the locking rod 71 sliding in the unlocked position in the locking direction R, the second support component 44 will not be able to pivot in order to slide in the sliding direction V, even if the locking mechanism unlocking portion 74 of the locking mechanisms 68, 70 is aligned with the provided locking recess 62 and within the sliding rails 38, 40. On the one hand, this sliding is prevented by the blocking mechanism 102, and on the other hand, it will be impossible to move the second support component 44 to a pivot position around the pivot axis S that would allow the second support component 44 to slide to the auxiliary device mounting position after the blocking action of the first blocking mechanism 102 is released. The locking rod 71 will already be prevented from coming out of the locking recess 62 by the second blocking mechanism 104 which covers the second support component 44 in the area of ​​its support body 48.

[0047] Finally, it should be noted that the detachable connection of an auxiliary device to a construction machine using a support assembly according to the present invention can also be used with construction machines of different structures or used in other work processes, such as wheel loaders, excavators, road milling machines, and asphalt finishers. For example, if the cab of such a construction machine is open, i.e., without a roof, the support assembly according to the present invention can also be attached to other areas of such construction machine, such as the bonnet or other covered areas.
