Description

Technical Field

[0001] The present application relates to the field of hanging basket protection devices, and in particular to a hanging basket rain protection device for cantilever casting. Background Art

[0002] In construction, hanging basket is a common aerial work equipment, especially in cantilever casting construction, it can improve the work efficiency of workers. However, the use of hanging basket will be subject to certain restrictions during construction on rainy days. In order to ensure the smooth progress of construction, some rain protection measures must be taken.

[0003] The existing rainproof measure is to install a rainproof awning above the hanging basket. In order to improve the effect of the rainproof awning in resisting heavy rain and prevent it from shifting, the installation between the rainproof awning and the hanging basket is often set relatively tightly to improve the installation strength. However, this also makes the installation of the rainproof awning more inconvenient. Summary of the Invention

[0004] In order to take into account both installation convenience and installation stability, the present application provides a hanging basket rain protection device for cantilever casting.

[0005] This application provides a cantilever casting hanging basket rain protection device, which adopts the following technical solutions:

[0006] A hanging basket rainproof device for cantilever casting comprises a plurality of booms mounted on the hanging basket and distributed vertically and horizontally, a skeleton assembly that can be rolled up and wrapped around the booms, a plurality of rainproof cloths, a first connecting assembly and a second connecting assembly; wherein the skeleton assembly comprises a plurality of transversely arranged steel strips, adjacent strips are hingedly connected, the skeleton assembly is mounted on the boom via the first connecting assembly, two transversely adjacent skeleton assemblies in the expanded state are fixedly connected via the second connecting assembly, the strips of the skeleton assemblies in the expanded state are arranged at an angle, and the ends of the strips of two longitudinally adjacent skeleton assemblies in the expanded state overlap; the rainproof cloths are simultaneously laid on the upper surfaces of the plurality of skeleton assemblies, the edges of adjacent rainproof cloths overlap, and avoidance gaps for the booms to pass through are opened at the edges of the rainproof cloths.

[0007] By adopting the above technical solution, during normal construction, the skeleton assembly is rolled up and wrapped around the hanger, and the rainproof device occupies less space, which can ensure the normal progress of construction.

[0008] When it rains, the skeleton components can be unfolded horizontally. At this time, the two adjacent skeleton components in the horizontal direction are fixedly connected by the second connecting component, and then the skeleton components are tilted longitudinally so that the ends of the strips of the two adjacent skeleton components in the longitudinal direction are overlapped, thereby completing the preliminary combination of all skeleton components. At this time, a complete skeleton surface is formed, and then the rainproof cloth is laid on the skeleton surface, that is, the installation of the rainproof device is convenient.

[0009] In addition, the rainproof device is connected to the hanger through a first connecting assembly, that is, the hanger is used as the force base, and the hanger is used to suspend the hanging basket and the hanger is in a prestressed tensioned state. Therefore, the position and strength of the hanger are relatively stable, thereby improving the stability of the force base of the rainproof device, and then improving the stability of the rainproof device.

[0010] Secondly, the skeleton components are tilted, so that the downward force of rainwater can be converted into a horizontal force applied to the hanger. The skeleton components are tilted in pairs, so that the horizontal forces of the hangers can offset each other, thereby indirectly improving the installation strength of the skeleton components.

[0011] Optionally, the first connecting assembly includes a connecting ring, a first connecting tube and a fixing structure, wherein the connecting ring is slidably mounted on the boom, and the fixing structure is used to fix or release the connecting ring and the boom; the connecting ring is hinged with an insert rod, and the insert rod is inserted into the end of the first connecting tube, the first connecting tube is parallel to the strip, and the strip located on one side of the skeleton assembly is hingedly connected to the first connecting tube, and the strip located on the other side of the skeleton assembly is connected to the second connecting assembly.

[0012] By adopting the above technical solution, on the one hand, the first connecting tube can be rotated from a vertical state to an inclined state through the articulation of the inserted rod. The first connecting tube in the vertical state can better fit the hanger and wrap the skeleton assembly around the hanger, while the first connecting tube in the inclined state can drive multiple strips to tilt together, so as to facilitate the tilt and fixation of the skeleton assembly in the unfolded state.

[0013] Secondly, the connecting ring and fixing structure allow the frame components and the boom to be fixed at different heights, allowing the heights of the different connection nodes of each frame component to be adjusted, thereby adjusting the tilt angle of the rainproof surface formed by the tarpaulin. For example, adjusting the tarpaulin to a horizontal tilt allows rainwater to drain through this horizontal tilt, thereby reducing the accumulation of rainwater on the tarpaulin surface.

[0014] Optionally, the fixing structure includes a rubber bite portion fixed to the end of the insertion rod; when the insertion rod is swung downward, the bite portion abuts against the surface of the suspension rod.

[0015] By adopting the above technical solution and setting the engaging portion, when the first connecting tube and the insertion rod swing upward, the engaging portion has no contact with the suspension rod, so the position of the skeleton assembly relative to the suspension rod can be changed by moving the connecting ring up and down; when the first connecting tube and the insertion rod swing downward to the expanded state, the engaging portion abuts against the surface of the suspension rod, thereby fixing the position of the connecting ring.

[0016] Moreover, when the skeleton assembly is subjected to the downward force of rainwater, the downward force will force the first connecting pipe to continue to swing downward, thereby making the abutment between the bite portion and the suspension rod tighter, the connection strength greater, and being able to better resist the downward force of rainwater.

[0017] In addition, the bite part is made of rubber, which has a high friction coefficient and high elasticity, and can buffer and shock-absorb the downward force.

[0018] Optionally, the second connecting assembly includes a second connecting tube, which is parallel to the strip, and the strip located on the side of the skeleton assembly away from the first connecting tube is hingedly connected to the second connecting tube; a magnetic part is provided on the surface of the second connecting tube, and when the skeleton assembly is rolled up on the suspension rod, the magnetic part of the second connecting tube is magnetically connected to the outermost strip; a T-shaped plug is fixed on the outer peripheral surface of the second connecting tube, and an introduction hole is opened on the outer peripheral surface of the first connecting tube, and a matching hole is opened on the hole wall along the axial direction of the first connecting tube, and the matching hole is used to cooperate with the plug.

[0019] By adopting the above technical solution, on the one hand, by utilizing the cooperation of the magnetic suction parts, the winding stability of the skeleton component can be improved, and it is not easy to fall apart. In addition, the improved winding stability can also increase the winding friction between the skeleton component and the suspension rod.

[0020] Secondly, through the cooperation between the insertion rod and the first connecting tube, the first connecting tube can slide axially for a certain distance, so that it is convenient for the insertion block to pass through the introduction hole in sequence along the axial direction and enter the matching hole, thereby realizing the connection between the first connecting tube and the second connecting tube, and then realizing the connection between the two adjacent skeleton components in the horizontal direction.

[0021] Third, when it is necessary to protect part of the hanging basket from rain, the two adjacent skeleton components can be vertically overlapped, that is, the second connecting pipe and the first connecting pipe on one skeleton component are respectively connected to the first connecting pipe and the second connecting pipe of the other skeleton component, thereby further improving the protection strength of the local rain.

[0022] Optionally, it also includes steel strands and a prestressed stress applying structure. The upper ends of two adjacent longitudinal strips are abutted by spring sheets. A pull ring is fixed to the upper end of the first connecting tube. The pull rings are arranged at intervals along the transverse direction, and two adjacent pull rings are staggered along the longitudinal direction. A support rod is fixed to one end of the steel strand, and the support rod abuts against one side of each transversely arranged skeleton component. The prestressed stress applying structure is installed on the other side of each transversely arranged skeleton component. The other end of the steel strand passes through each pull ring in turn along the transverse direction and is connected to the prestressed stress applying structure. The prestressed stress applying structure is used to tighten the steel strand, and the tightened steel strand is wavy.

[0023] By adopting the above technical solution, a prestressing structure is set up to tighten the wavy steel strands. The tension of the steel strands will be applied to the longitudinally adjacent skeleton components through the pull ring, thereby forcing the longitudinally adjacent skeleton components to approach each other to compress the spring pieces, so that the entire skeleton surface has internal stress, which can effectively resist the impact of rainwater.

[0024] In addition, the pull rings are staggered at intervals, so that some of the skeleton components are closer and some are not close, so that the longitudinally adjacent skeleton components are in an interlocking and staggered shape, thereby greatly improving the ability to resist lateral deformation and thus improving the structural stability of the rainproof device.

[0025] Optionally, the prestressed structure includes a support plate, a threaded sleeve and a threaded rod, the support plate can be detachably mounted on one side of each transversely arranged skeleton assembly, the threaded sleeve is fixed on the support plate, the threaded rod is fixedly connected to one end of the steel strand, and the threaded rod is threadedly connected to the threaded sleeve.

[0026] By adopting the above technical solution, the threaded rod and the threaded sleeve are threadedly connected to apply axial force to the steel strand to tighten the steel strand.

[0027] Optionally, the connecting ring is provided with an operating rod and a traction rope, the upper end of the operating rod is connected to the connecting ring, the operating rod is parallel to the boom, the upper end of the traction rope is connected to the middle of the first connecting tube, and the lower end of the traction rope is lower than the operating rod.

[0028] By adopting the above technical solution, the operating rod can be used to control the up and down movement of the connecting ring, thereby facilitating the adjustment of the height position of the connection node of the skeleton assembly. When the operating rod drives the connecting ring to move upward, the friction between the engaging part and the suspension rod will force the insertion rod to swing upward, thereby releasing the fixation to facilitate the upward movement of the connecting ring.

[0029] When the connecting ring needs to be moved downward, the traction rope needs to be pulled downward to drive the first connecting pipe to swing upward to release the fixation between the connecting ring and the boom, and then the connecting ring can be moved downward using the operating lever.

[0030] Optionally, the operating rod is provided with a through-hole along the axial direction, and the traction rope passes through the through-hole.

[0031] By adopting the above technical solution, the operating rod can accommodate the traction rope, thereby avoiding the risk caused by the traction rope being entangled with the external structure.

[0032] Optionally, the bottom of the connecting ring is coaxially connected to a rotating ring, the upper end of the operating rod is fixedly connected to the rotating ring, the connecting ring is fixed with a guide ring, the guide ring is coaxially arranged with the connecting ring, and the traction rope passes around the guide ring from top to bottom.

[0033] By adopting the above technical solution, on the one hand, the guide ring can guide the traction rope, so that the downward pulling force of the traction rope can be better applied to the first connecting pipe.

[0034] Secondly, by setting a rotating ring, the circumferential angle of the traction rope and the operating rod can be changed. When the traction rope and the operating rod are located directly below the first connecting tube, the traction rope is pulled down, and the traction rope will drive the first connecting tube to continue to swing downward to change the swing angle of the first connecting tube, while also increasing the abutment strength between the bite part and the suspension rod.

[0035] Optionally, it also includes rubber half rings arranged in one-to-one correspondence with the suspension rod, and two rubber half rings are provided. The two rubber half rings are connected by snap-fitting, and the two rubber half rings surround the suspension rod, and the rubber half rings clamp the part of the rainproof cloth covering the surface of the suspension rod.

[0036] By adopting the above technical solution, the rubber half ring can reduce the rain leakage gap between the tarpaulin and the boom.

[0037] Secondly, the rubber half ring clamps the tarpaulin to reinforce the tarpaulin.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. By providing a deployable frame assembly, a first connecting assembly, a second connecting assembly, and a rainproof sheet, the rainproof device can be quickly and conveniently installed. Furthermore, the use of the hanger rod as a force-bearing foundation is relatively stable, and the tilted frame assembly can convert the downward force of rainwater into a horizontal force applied to the hanger rod. The tilted frame assembly, in pairs, allows the horizontal forces of the hanger rods to offset each other, thereby indirectly improving the installation strength of the frame assembly.

[0040] 2. The connecting ring and fixing structure can achieve different height positions of the frame assembly and the suspension rod, so as to adjust the height of the different connection nodes of each frame assembly, thereby adjusting the inclination angle of the rainproof surface formed by the tarpaulin, so that rainwater is discharged through this horizontal inclination, thereby reducing the accumulation of rainwater on the surface of the tarpaulin;

[0041] 3. By setting up a prestressing structure to tighten the wavy steel strands, the tension of the steel strands will be applied to the longitudinally adjacent frame components through the pull ring, thereby forcing the longitudinally adjacent frame components to approach each other to compress the spring pieces, so that the entire frame surface has internal stress, which can effectively resist the impact of rainwater.

[0053] The following is combined with Figure 1-10 This application is described in further detail.

[0054] Example 1 of the present application discloses a hanging basket rain protection device for cantilever casting.

[0055] Reference Figure 1 and Figure 2The rainproof device of the hanging basket 10 for cantilever casting includes a plurality of suspension rods 20 installed on the hanging basket 10 and distributed vertically and horizontally, a skeleton component 1 that can be rolled up and wrapped around the suspension rods 20, a plurality of rainproof cloths 2, a first connecting component 3 and a second connecting component 5.

[0056] The booms 20 are arranged in three groups distributed longitudinally, wherein the upper ends of the first group of booms 20 and the third group of booms 20 are fixedly connected to the trusses on the bridge, the lower ends of the first group of booms 20 and the third group of booms 20 are fixedly connected to the crossbeams of the hanging basket 10, the upper ends of the second group of booms 20 are fixedly connected to the trusses on the bridge, and the lower ends of the second group of booms 20 are higher than the hanging basket 10 and are suspended in the air.

[0057] like Figure 2 As shown, the skeleton assembly 1 includes a plurality of transversely arranged steel strips 11 , adjacent strips 11 are hingedly connected, and a rubber layer (not shown) is provided on the surface of the strips 11 .

[0058] like Figure 3 As shown, the skeleton assembly 1 is installed on the boom 20 through the first connecting assembly 3. The first connecting assembly 3 includes a connecting ring 32, a first connecting tube 31 and a fixing structure. The first connecting tube 31 is parallel to the strip 11, and the strip 11 located on one side of the skeleton assembly 1 is hingedly connected to the first connecting tube 31.

[0059] The connecting ring 32 is slidably mounted on the boom 20, and the fixing structure is used to fix or release the connecting ring 32 to the boom 20. That is, the height position of the connecting ring 32 relative to the boom 20 can be adjusted through the fixing structure. The second group of booms 20 can have one connecting ring 32, one corresponding to the two first connecting tubes 31. The second group of booms 20 can have two connecting rings 32, one corresponding to the two first connecting tubes 31.

[0060] The connecting ring 32 is penetrated by an avoidance groove 321 , in which an insertion rod 34 is hinged. The insertion rod 34 is inserted into the end of the first connecting tube 31 , that is, the first connecting tube 31 can move axially and rotate circumferentially relative to the insertion rod 34 .

[0061] like Figure 2 、 Figure 4 As shown, two laterally adjacent skeleton components 1 in the expanded state are fixedly connected by a second connecting component 5. Specifically, the second connecting component 5 includes a second connecting tube 51, which is parallel to the strip 11. The strip 11 located on the side of the skeleton component 1 away from the first connecting tube 31 is hingedly connected to the second connecting tube 51.

[0062] A magnetic part 53 is provided on the surface of the second connecting tube 51, and the magnetic part 53 is a magnet. The strip 11 is made of steel. A T-shaped plug 52 is fixed to the outer peripheral surface of the second connecting tube 51, and an introduction hole 311 is provided on the outer peripheral surface of the first connecting tube 31. The hole wall of the introduction hole 311 is provided with a matching hole 312 along the axial direction of the first connecting tube 31.

[0063] During normal construction, that is, when the skeleton assembly 1 is not in use, the first connecting tube 31 is swung to a vertical state through the hinge of the insertion rod 34 and the connecting ring 32, and then the steel frame assembly is rolled up and wrapped around the hanger 20, while the second connecting tube 51 located on the free side of the steel frame assembly is magnetically connected to the outermost strip 11 by means of the magnetic suction part 53 thereon, and the winding friction force of the rubber layer of the strip 11 is used to ensure that there is a certain friction force between the steel frame assembly and the hanger 20, so that the steel frame assembly can be more firmly wrapped around the hanger 20, thereby reducing the space occupied by the steel frame assembly to ensure the normal progress of construction.

[0064] During construction on rainy days, the rolled-up state of the steel frame assembly is released, and then the steel frame assembly is unfolded laterally. At this time, the second connecting tube 51 on the steel frame assembly moves to the first connecting tube 31 of a laterally adjacent steel frame assembly, and the first connecting tube 31 is made to slide axially for a certain distance through the insertion rod 34 and the first connecting tube 31, so that the first connecting tube 31 can slide axially for a certain distance, so that it is convenient for the insert block 52 to pass through the introduction hole 311 in sequence along the axial direction and enter the matching hole 312, thereby realizing the connection between the first connecting tube 31 and the second connecting tube 51, and then realizing the connection between the two laterally adjacent skeleton components 1, and then utilizing the swingable movement of the first connecting tube 31 to swing the first connecting tube 31 downward to an inclined state. At this time, the ends of the strips 11 of the two longitudinally adjacent unfolded skeleton components 1 directly abut each other, thereby completing the preliminary combination of all skeleton components 1, and forming a complete skeleton surface at this time.

[0065] The tarpaulins 2 are provided in multiple pieces, which can be laid on the frame surface formed by the frame components 1. The edges of adjacent tarpaulins 2 overlap, completing the quick installation of the rainproof device. The edges of the tarpaulins 2 are provided with clearance gaps 21 for the suspension rods 20 to pass through, thus preventing interference with the suspension rods 20.

[0066] Furthermore, since the rainproof device is connected to the hanger 20 via the first connecting assembly 3, that is, the hanger 20 is used as the force basis, the position and strength of the hanger 20 are relatively stable, thereby improving the stability of the connection node of the rainproof device.

[0067] Secondly, the skeleton assembly 1 is tilted, so it can convert the downward force of rainwater into a horizontal force applied to the hanger 20, and the skeleton assembly 1 is tilted in pairs, so that the horizontal forces of the hanger 20 can offset each other, thereby indirectly improving the installation strength of the skeleton assembly 1.

[0068] Finally, through the connecting ring 32 and the fixing structure, the skeleton component 1 and the hanger 20 can be fixed at different height positions to adjust the height of different connection nodes of each skeleton component 1, thereby adjusting the inclination angle of the rainproof surface formed by the rainproof cloth 2.

[0069] For example, the tarpaulin 2 can be adjusted to be tilted in the lateral direction so that rainwater can be discharged through the lateral tilt, thereby reducing the accumulation of rainwater on the surface of the tarpaulin 2 .

[0070] like Figure 3 As shown, the fixing structure includes a rubber bite portion 33 fixed to the lower end of the insertion rod 34, and the surface of the bite portion 33 is provided with bite teeth (not shown in the figure).

[0071] When the insertion rod 34 and the first connecting tube 31 swing upward, the bite portion 33 is away from the suspension rod 20, that is, there is no contact between the bite portion 33 and the suspension rod 20, so the position of the skeleton assembly 1 relative to the suspension rod 20 can be changed by moving the connecting ring 32 up and down; when the first connecting tube 31 and the insertion rod 34 swing downward to the expanded state, the bite portion 33 abuts against the surface of the suspension rod 20, and the position of the connecting ring 32 is fixed by the abutting friction force.

[0072] In other embodiments, the fixing structure may be a bolt, which is threadedly connected to the connecting ring 32 , and the end of the bolt may abut against the surface of the boom 20 , and the abutting friction force is used to limit the height of the connecting ring 32 .

[0073] Example 2

[0074] The difference between Example 2 and Example 1 is that Figure 5 、 Figure 6 As shown, the connecting ring 32 is provided with an operating rod 36 and a traction rope 35. Specifically, the bottom of the connecting ring 32 is rotatably connected to a rotating ring 38, and the rotating ring 38 is coaxially arranged with the connecting ring 32. The operating rod 36 is parallel to the boom 20, and the upper end of the operating rod 36 is fixedly connected to the rotating ring 38. A through hole 361 is opened axially through the operating rod 36.

[0075] A guide ring 37 is fixed to the connecting ring 32 . The guide ring 37 is coaxially arranged with the connecting ring 32 and is lower than the first connecting pipe 31 .

[0076] The upper end of the traction rope 35 is connected to the middle of the first connecting tube 31 , and the lower end of the traction rope 35 passes through the guide ring 37 from top to bottom and passes through the through hole 361 of the operating rod 36 , and the lower end of the traction rope 35 is lower than the operating rod 36 .

[0077] When the upward movement distance of the connecting ring 32 needs to be adjusted, the operator can hold the operating rod 36 and use the operating rod 36 to drive the connecting ring 32 to move upward, and the friction between the bite part 33 and the suspension rod 20 will force the insertion rod 34 to swing upward, thereby releasing the fixation to facilitate the upward movement of the connecting ring 32.

[0078] When the downward movement distance of the connecting ring 32 needs to be adjusted, Figure 5 As shown, the operating rod 36 is moved to the opposite side of the insertion rod 34, and then the traction rope 35 is pulled downward to drive the first connecting tube 31 to swing upward to release the fixation between the connecting ring 32 and the suspension rod 20, and then the connecting ring 32 is moved downward using the operating rod 36.

[0079] When the tilted skeleton assembly 1 needs to be reinforced for the second time, the operating rod 36 is moved to the same side of the insertion rod 34, that is, when the traction rope 35 and the operating rod 36 are located directly below the first connecting tube 31, the traction rope 35 is pulled down, and the traction rope 35 will drive the first connecting tube 31 to continue to swing downward to change the swing angle of the first connecting tube 31, while also increasing the abutment strength between the bite portion 33 and the suspension rod 20.

[0080] Example 3

[0081] The difference between Example 3 and Example 1 is that Figure 7 、 Figure 8 As shown, the upper ends of two strips 11 of longitudinally adjacent skeleton components 1 are abutted against each other by elastic pieces 9 , and the rainproof device further includes steel strands 6 and a prestressing structure 7 .

[0082] A pull ring 62 is fixed at the bottom position of the upper end of the first connecting tube 31, and each pull ring 62 is arranged at intervals along the horizontal direction, that is, there are only two pull rings 62 on the three laterally adjacent skeleton components 1, and the two adjacent pull rings 62 are staggered along the longitudinal direction. The steel strand 6 is located below the skeleton component 1, and a support rod 61 is fixed at one end of the steel strand 6. The support rod 61 abuts against one side of each laterally arranged skeleton component 1, and a prestressed structure 7 is installed on the other side of each laterally arranged skeleton component 1. The other end of the steel strand 6 passes through each pull ring 62 in turn along the horizontal direction and is connected to the prestressed structure 7. The prestressed structure 7 is used to tighten the steel strand 6, and the tightened steel strand 6 is wavy.

[0083] like Figure 9 As shown, the prestressed structure 7 includes a support plate 71, a threaded sleeve 72 and a threaded rod 73. The support plate 71 can be detachably installed on one side of each transversely arranged skeleton assembly 1. Specifically, a transversely arranged support rod 74 is provided on the first connecting tube 31, and the support rod 74 passes through the support plate 71 to realize the detachable installation of the support plate 71.

[0084] The threaded sleeve 72 is fixed on the support plate 71, and the threaded rod 73 is fixedly connected to one end of the steel strand 6. The threaded rod 73 is threadedly connected to the threaded sleeve 72, that is, the rotation of the threaded rod 73 is used to apply axial force to the steel strand 6 to tighten the steel strand 6.

[0085] In this way, the tension of the steel strand 6 will be applied to the longitudinally adjacent frame components 1 through the pull ring 62, thereby forcing the longitudinally adjacent frame components 1 to approach each other to compress the spring piece 9, so that the entire frame surface has internal stress, which can effectively resist the impact of rainwater.

[0086] Furthermore, the longitudinally adjacent skeleton components 1 are interlocked and staggered, thereby greatly improving the ability to resist lateral deformation, thereby improving the structural stability of the rainproof device.

[0087] Example 4

[0088] The difference between Example 4 and Example 1 is that Figure 10 As shown, the rainproof device further includes a rubber half ring 8 arranged in one-to-one correspondence with the suspension rod 20, and two rubber half rings 8 are provided. The two rubber half rings 8 are connected by an interference fit of the hole shaft.

[0089] After the tarpaulin 2 is laid, the portion of the tarpaulin 2 surrounding the hanger 20 is arranged so that the edge of the avoidance gap 21 of the tarpaulin 2 fits and covers the surface portion of the hanger 20, and then two rubber half rings 8 are used to surround the hanger 20 so that the two rubber half rings 8 are connected to each other. At this time, the rubber half rings 8 clamp the portion of the tarpaulin 2 covering the surface of the hanger 20. In this way, the rubber half rings 8 can fill the leaking gap between the small tarpaulin 2 and the hanger 20.

[0090] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
