Abstract
Description
Technical Field
[0001] This application relates to the field of elevator component technology, and in particular to limit auxiliary mechanisms, elevator guide devices, and inclined elevators. Background Technology
[0002] Inclined escalators (hereinafter referred to as "inclined escalators") are a type of horizontal and vertical transportation equipment widely used in public places such as shopping malls, subway stations, airports, and train stations. They provide convenient transportation for people with disabilities, the elderly, or young children, and are favored for their convenience and efficiency. However, during the actual operation of an inclined escalator, mechanical failures, control system malfunctions, or external interference (such as improper passenger behavior) may cause the steps to exceed the normal operating range, leading to dangerous accidents such as derailment. This can result in unstable operation of the inclined escalator and easily cause safety incidents.
[0003] In related technologies, to improve the operational safety of inclined elevators, manufacturers typically install width-direction limit protection devices on the upper and lower turning guide rails to provide lateral limiting force at the turning guide rails, thereby preventing derailment. However, these limit protection devices are often absent in the inclined section of the elevator, making it prone to vertical jolts and subsequent tipping accidents. Consequently, the stability of inclined elevators remains relatively poor. Utility Model Content
[0004] Therefore, it is necessary to provide a limit auxiliary mechanism, an elevator guide device, and an inclined elevator to address the issue of how to improve the operational stability of inclined elevators in the vertical direction.
[0005] A limiting auxiliary mechanism is provided to assist the guiding movement of a transport component on an elevator guide rail assembly; the elevator guide rail assembly has a first surface and a second surface opposite to each other along its own height direction, and the elevator guide rail assembly is inclined relative to the height direction; the limiting auxiliary mechanism includes:
[0006] A support bracket for connecting to the transport assembly;
[0007] The limiting wheel assembly includes a first limiting wheel and a second limiting wheel; the first limiting wheel and the second limiting wheel are spaced apart and are rotatably mounted on the bearing bracket; the first limiting wheel is used for rolling engagement with the first surface, and the second limiting wheel is used for rolling engagement with the second surface.
[0008] In one embodiment, at least a portion of the first limiting wheel and at least a portion of the second limiting wheel are offset along a direction perpendicular to the height.
[0009] In one embodiment, the limiting auxiliary mechanism further includes a support member connected to the bearing bracket, the position of the support member relative to the bearing bracket in the height direction being adjustable; the bearing bracket is movably disposed on the elevator guide rail assembly, and the support member is used to abut against and support the elevator guide rail assembly; and when the support member abuts against and supports the elevator guide rail assembly, the support member drives the bearing bracket to move in a direction away from the elevator guide rail assembly, so as to drive the transport component to be spaced apart from the elevator guide rail assembly;
[0010] And / or, both the first limiting wheel and the second limiting wheel are detachably connected to the bearing bracket.
[0011] In one embodiment, the limiting auxiliary mechanism further includes a cleaning component connected to the support bracket; the cleaning component abuts against the first surface.
[0012] In one embodiment, the cleaning component includes a scraper connected to the support bracket; the scraper has an inclined structure for abutting against the first surface; and the inclined structure is gradually inclined relative to the height direction in a direction away from the support bracket.
[0013] In one embodiment, one of the cleaning component and the support bracket is provided with a groove, and the other is provided with a protrusion; at least a portion of the groove extends along the height direction, and when the cleaning component and the first surface abut against each other, the protrusion can be slidably disposed in the groove.
[0014] An elevator guiding device includes an elevator guide rail assembly and a limiting auxiliary mechanism as described in the above embodiments; the elevator guide rail assembly extends along its own length direction and is inclined relative to the height direction.
[0015] In one embodiment, the elevator guiding device includes two elevator guide rail assemblies and at least two limiting auxiliary mechanisms. The two elevator guide rail assemblies are arranged opposite to each other and spaced apart along their own width direction. There are two limiting auxiliary mechanisms arranged opposite to each other and spaced apart along the width direction, and the two limiting auxiliary mechanisms are respectively matched with the two elevator guide rail assemblies.
[0016] In one embodiment, the two elevator guide rail assemblies are a first elevator guide rail assembly and a second elevator guide rail assembly, and the two support brackets are a first support bracket and a second support bracket; the first support bracket is guided and engaged with the first elevator guide rail assembly, and the second support bracket is guided and engaged with the second elevator guide rail assembly.
[0017] The first support bracket is provided with a first limiting part, which is located on the side of the first support bracket away from the second support bracket. The first limiting part is used to abut against the side edge of the first elevator guide rail assembly. The second support bracket is provided with a second limiting part, which is located on the side of the second support bracket away from the first support bracket. The second limiting part is used to abut against the side edge of the second elevator guide rail assembly.
[0018] An inclined elevator includes a transport component and an elevator guide device as described in the above embodiments. The transport component is connected to a support frame and is used to load passengers.
[0019] The aforementioned limiting auxiliary mechanism, elevator guiding device, and inclined elevator, in which the first and second limiting wheels respectively roll in engagement with the first and second surfaces of the elevator guide rail assembly, form a bidirectional constraint in the height direction. This allows the limiting auxiliary mechanism to help counteract the swaying or tilting torque of the transport component in the height direction, improving the stability of the transport component's movement in the height direction. Furthermore, during the ascent or descent of the inclined elevator, the rolling engagement of the first and second limiting wheels can decompose gravity onto the two contact surfaces of the guide rail. Vibration is reduced through rolling friction rather than surface-to-surface friction, ensuring smooth and stable elevator operation and improving the safety of elevator transportation.

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0028] See Figure 1 as well as Figure 2 As shown, this application provides an elevator guiding device including a limiting auxiliary mechanism 100 and an elevator guide rail assembly 200. The limiting auxiliary mechanism 100 includes a support bracket 110 and a limiting wheel assembly 120.
[0029] To facilitate understanding, the following detailed explanation will be provided in conjunction with the supporting structure of the elevator guide device.
[0030] This application also provides an inclined elevator, including the elevator guiding device and the transport component 300 described in the above embodiments. The transport component 300 is connected to the support bracket 110. The transport component 300 is used to carry passengers. The inclined elevator can be, but is not limited to, a straight inclined elevator (where the guide rails of a straight inclined elevator are horizontally arranged), or an inclined elevator (where the guide rails of an inclined elevator are inclined), etc.
[0031] Specifically, such as Figure 2 as well as Figure 3As shown, the elevator guide rail assembly 200 has a first surface 200a and a second surface 200b along its height direction X. The elevator guide rail assembly 200 is also inclined relative to the height direction X. The limiting wheel assembly 120 includes a first limiting wheel 121 and a second limiting wheel 122. The first limiting wheel 121 and the second limiting wheel 122 are spaced apart and rotatably mounted on the support bracket 110. The first limiting wheel 121 is used for rolling engagement with the first surface 200a, and the second limiting wheel 122 is used for rolling engagement with the second surface 200b. The elevator guide rail assembly 200 can extend along its length direction Y, and the limiting wheel assembly 120 guides and engages with the elevator guide rail assembly 200 along its length direction Y.
[0032] Understandably, the first limiting wheel 121 and the second limiting wheel 122 roll in contact with the first surface 200a and the second surface 200b of the elevator guide rail assembly 200, respectively, forming a bidirectional constraint in the height direction X. This allows the limiting auxiliary mechanism 100 to help counteract the swaying or tilting torque of the transport assembly 300 in the height direction X, thereby improving the stability of the transport assembly 300's movement in the height direction X. In one example scenario, if the transport assembly 300 is unevenly loaded, causing it to tilt towards the first surface 200a, the first limiting wheel 121 will be compressed, increasing the rolling resistance. At the same time, the gap between the second limiting wheel 122 and the second surface 200b decreases or the pressure increases, generating a reverse torque that forces the transport assembly 300 back to its upright position.
[0033] Furthermore, during the ascent or descent of the inclined elevator, the rolling engagement of the first limiting wheel 121 and the second limiting wheel 122 decomposes the gravity onto the two contact surfaces of the guide rail. This rolling friction, rather than surface-to-surface friction, reduces vibration and ensures smooth and stable elevator operation. In one example scenario, during the ascent or descent of the inclined elevator, the transport component 300 is subjected to a component of gravity (sliding force). The rolling engagement of the first limiting wheel 121 and the second limiting wheel 122 decomposes this component of gravity onto the two contact surfaces of the guide rail. This rolling friction, rather than surface-to-surface friction, reduces vibration and ensures smooth and stable elevator operation, improving the safety of elevator transport.
[0034] It should be noted that the mounting axes along the height direction X between the first limiting wheel 121 and the second limiting wheel 122 in the above embodiments can be on the same straight line or on different straight lines.
[0035] In some embodiments, see back Figure 3 At least a portion of the first limiting wheel 121 and at least a portion of the second limiting wheel 122 are offset along the direction perpendicular to the height X. That is, at least a portion of the first limiting wheel 121 and at least a portion of the second limiting wheel 122 are offset along the direction of width Z.
[0036] Understandably, in one example scenario, during the operation of an inclined elevator, the car may experience lateral displacement due to centrifugal force (curved rail section) or lateral wind load. In this case, setting the first limiting wheel 121 and the second limiting wheel 122 staggered in the height direction X provides contact pressure on different sides of the elevator guide rail assembly 200 in the width direction Z, improving the anti-balancing ability of the limiting auxiliary mechanism 100 and suppressing lateral swaying of the car. In another example scenario, when the load distribution inside the car is uneven (e.g., passengers are standing at an angle), setting the first limiting wheel 121 and the second limiting wheel 122 staggered in the height direction X helps balance the contact force in the width direction Z, preventing overload of one side of the elevator guide rail assembly 200 and improving the operational stability of the inclined elevator.
[0037] That is, the first limiting wheel 121 and the second limiting wheel 122 are staggered in the width direction Z of the guide rail (in one example, the first limiting wheel 121 is located near the left side of the elevator guide rail assembly 200, and the second limiting wheel 122 is located near the right side of the elevator guide rail assembly 200), which helps to improve the balance of the limiting auxiliary mechanism 100 in the width direction Z of the elevator guide rail assembly 200, thereby enhancing the anti-offset capability of the transport assembly 300 in the width direction Z, and thus improving the operational stability of the inclined elevator.
[0038] In some embodiments, combined with Figure 2 as well as Figure 4 As shown, the limiting auxiliary mechanism 100 also includes a cleaning component 130. The cleaning component 130 is connected to the support bracket 110. The cleaning component 130 abuts against the first surface 200a. Thus, by having at least a portion of the cleaning component 130 abut against the first surface 200a, the cleaning component 130 can remove dust and other foreign objects from the first surface 200a upon contact, thereby improving the running stability of the limiting wheel assembly 120 on the elevator guide rail assembly 200.
[0039] Furthermore, in one embodiment, see back Figure 4 The cleaning component 130 includes a scraper 131, which is connected to the support bracket 110. The scraper 131 has an inclined structure for abutting against the first surface 200a. The inclined structure is gradually inclined relative to the height direction X in a direction away from the support bracket 110.
[0040] Thus, the inclined structure is gradually tilted relative to the height direction X in a direction away from the support bracket 110, so that when the scraper 131 abuts against the first surface 200a, the inclined structure can perform a cleaning action of first scooping up and then pushing away foreign objects such as dust on the first surface 200a, so as to use shearing force and guiding action to peel off foreign objects such as dust and oil.
[0041] Additionally, in one embodiment, see back Figure 4The cleaning assembly 130 also includes a connecting plate 132, which is connected to the support bracket 110, and at least a portion of the connecting plate 132 abuts against the support bracket 110. The scraper 131 is connected to the support bracket 110 via the connecting plate 132. Thus, the abutting fit between the connecting plate 132 and the support bracket 110 ensures the secure installation of the cleaning assembly 130 on the elevator guide rail assembly 200, reduces loosening or displacement caused by vibration or external forces, and enhances the structural strength of the cleaning assembly 130.
[0042] In other embodiments, see back Figure 4 One of the cleaning component 130 and the support bracket 110 is provided with a groove 130a, and the other is provided with a protrusion 110a. At least part of the groove 130a extends upward along the height direction X. When the cleaning component 130 and the first surface 200a abut against each other, the protrusion 110a can be slidably disposed in the groove 130a.
[0043] It is understandable that when the surfaces of the cleaning component 130 and the elevator guide rail assembly 200 are in contact, if the plane of the elevator guide rail assembly 200 protrudes due to foreign objects or poor design precision, or if the cleaning component 130 of the transport component 300 experiences bumps, the cleaning component 130 may move in the height direction X. If the cleaning component 130 and the elevator guide rail assembly 200 are fixedly connected in the height direction X, the clamping force between them may increase, potentially causing the limiting auxiliary mechanism 100 to derail and damage to parts. In this embodiment, the sliding groove 130a and the protrusion 110a provide flexible movement space for the contact between the cleaning component 130 and the support bracket 110, reducing the clamping force between the elevator guide rail assembly 200 and the cleaning component 130 during contact, thereby ensuring the stable movement of the limiting auxiliary mechanism 100 and preventing damage to parts.
[0044] It should be noted that the number of elevator guide rail components 200 mentioned above can be one, two, or even three, etc., without much restriction here.
[0045] Optionally, in one embodiment, as Figure 5 As shown, the elevator guiding device includes two elevator guide rail assemblies 200, which are arranged at a relative interval along their width direction Z. A limiting auxiliary mechanism 100 corresponds to and cooperates with each elevator guide rail assembly 200.
[0046] Thus, there are two elevator guide rail assemblies 200, and correspondingly, there can be two limit auxiliary mechanisms 100. This increases the contact points between the limit auxiliary mechanism 100 and the elevator guide rail assembly 200, thereby reducing the load-bearing burden when a single limit auxiliary mechanism 100 contacts a single elevator guide rail assembly 200. This is beneficial for improving the movement stability of the elevator guiding device, reducing the risk of damage to the elevator guide rail assembly 200, and extending its service life.
[0047] Furthermore, the two elevator guide rail assemblies 200 are arranged opposite each other, which can achieve force balance when the limit auxiliary mechanism 100 and the elevator guide rail assembly 200 abut against each other, thereby improving the movement stability of the elevator guiding device and reducing the wear of the elevator guide rail assembly 200.
[0048] In addition, in order to further improve the limiting movement performance of the limiting auxiliary mechanism 100 and the elevator guide device, combined with Figure 1 as well as Figure 5 As shown, in some embodiments, the two elevator guide rail assemblies 200 are respectively the first elevator guide rail assembly 210 and the second elevator guide rail assembly 220, and the two support brackets 110 are respectively the first support bracket 111 and the second support bracket 112. The first support bracket 111 is guided and engaged with the first elevator guide rail assembly 210, and the second support bracket 112 is guided and engaged with the second elevator guide rail assembly 220.
[0049] The first support bracket 111 is provided with a first limiting part 111a, which is located on the side of the first support bracket 111 away from the second support bracket 112. The first limiting part 111a is used to abut against the side edge of the first elevator guide rail assembly 210. The second support bracket 112 is provided with a second limiting part 112a, which is located on the side of the second support bracket 112 away from the first support bracket 111. The second limiting part 112a is used to abut against the side edge of the second elevator guide rail assembly 220.
[0050] Thus, the first support bracket 111 is provided with a first limiting part 111a, and the second support bracket 112 is provided with a second limiting part 112a. The first limiting part 111a and the second limiting part 112a respectively abut against the side edges of the first elevator guide rail assembly 210 and the second elevator guide rail assembly 220, thereby providing a limiting effect in the width direction Z. Combined with the cooperation of the first limiting wheel 121 and the second limiting wheel 122 in the above embodiment, the upper limit in the height direction X is achieved, thereby achieving the limiting in the height direction X and the width direction Z, forming a limiting surface, and improving the stability and safety of elevator operation.
[0051] In one embodiment, see back Figure 3The support bracket 110 includes a first body 110b and a second body 110c. The first body 110b is disposed opposite to the first surface 200a, and the second body 110c is bent and connected to the first body 110b. The second body 110c is disposed facing the side edge of the elevator guide rail assembly 200. A first limiting part 111a is disposed on the second body 110c of the first support bracket 111; a second limiting part 112a is disposed on the second body 110c of the second support bracket 112.
[0052] It should be noted that the number of limit auxiliary mechanisms 100 can be two, three, four, six, etc., and no further restrictions are imposed here.
[0053] Alternatively, in yet another embodiment, see back Figure 1 The number of limiting auxiliary mechanisms 100 can be four. Specifically, two limiting auxiliary mechanisms 100 are arranged opposite to each other and spaced apart along the length direction Y. Correspondingly, two first bearing supports 111 are arranged opposite to each other along the length direction Y and are guided and engaged with the first elevator guide rail assembly 210. Two other limiting auxiliary mechanisms 100 are arranged opposite to each other and spaced apart along the length direction Y. Correspondingly, two second bearing supports 112 are arranged opposite to each other along the length direction Y and are guided and engaged with the second elevator guide rail assembly 220. In this way, a fixed surface can be formed by the four limiting auxiliary mechanisms 100, thereby improving the support performance of the limiting auxiliary mechanisms 100 for the transport assembly 300.
[0054] Furthermore, in one embodiment, see... Figure 3 As shown, the first limiting wheel 121 is connected to the first body 110b; the second limiting wheel 122 is connected to the second body 110c. Thus, unlike designs where the first limiting wheel 121 and the second limiting wheel 122 are simultaneously installed on either the first body 110b or the second body 110c, the first limiting wheel 121 is connected to the first body 110b, and the second limiting wheel 122 is connected to the second body 110c. This reduces the size requirements of the first body 110b, and the first and second limiting wheels 121 and 122 do not obstruct installation, improving ease of installation.
[0055] To improve the motion stability of the transport component 300, in some embodiments, such as Figure 1 as well as Figure 2As shown, the inclined elevator also includes a guide wheel assembly 400, which is rotatably mounted on the transport component 300, and the transport component 300 is guided and engaged with the first surface 200a via the guide wheel assembly 400. Thus, the guide wheel assembly 400 provides guidance for the movement of the transport component 300, reducing the load on the limiting auxiliary mechanism 100 and improving the movement stability of the transport component 300. Furthermore, the guide wheel assembly 400 helps reduce the moving resistance of the transport component 300 and the first surface 200a, thereby improving the smoothness of the transport component 300's movement.
[0056] Optionally, in one embodiment, the guide wheel assembly 400 can be arranged one-to-one with and adjacent to the limiting auxiliary mechanism 100. In this way, the stress burden on the limiting auxiliary mechanism 100 can be reduced to the greatest extent and the motion stability of the moving component can be improved.
[0057] In conjunction with any embodiment of the aforementioned limiting auxiliary mechanism 100, such as Figure 2 , Figure 3 as well as Figure 4 As shown, the limiting auxiliary mechanism 100 also includes a support member 140, which is connected to the support bracket 110. The position of the support member 140 relative to the support bracket 110 in the height direction is adjustable. The support bracket 110 is movably disposed on the elevator guide rail assembly 200, and the support member 140 is used to abut against and support the elevator guide rail assembly 200. When the support member 140 abuts against and supports the elevator guide rail assembly 200, the support member 140 drives the support bracket 110 to move away from the elevator guide rail assembly 200, so as to drive the conveying component 300 to be spaced apart from the elevator guide rail assembly 200.
[0058] Thus, the support member 140 can adjust the distance between the bearing bracket 110 and the elevator guide rail assembly 200 according to the actual situation, and then adjust the distance between the transport component 300 and the elevator guide rail assembly 200 to enrich the installation scenarios of the limit auxiliary mechanism 100.
[0059] Specifically, in one example, in conjunction with the embodiment of the guide wheel assembly 400 described above, the guide wheel assembly 400 is detachably connected to the transport assembly 300. Due to long-term use, the guide wheel assembly 400 is prone to wear and tear, and therefore can be replaced periodically. In a replacement scenario, the support member 140 can abut against the elevator guide rail assembly 200 to achieve a lifting engagement, allowing the support member 140 to drive the load-bearing bracket 110 and the distance between the transport assembly 300 and the elevator guide rail assembly 200 to be adjustable. This allows for a spacing between the guide wheel assembly 400 and the elevator guide rail assembly 200, facilitating the removal and replacement of the guide wheel assembly 400 and improving the convenience and efficiency of its replacement.
[0060] In another example, when the bottom of the transport component 300 needs to be inspected, the support member 140 can be used to abut against the elevator guide rail assembly 200 to achieve a lifting engagement, so that the guide wheel assembly 400 and the elevator guide rail assembly 200 are spaced apart, making it easier to observe the bottom of the transport component 300 and improving the efficiency and quality of the inspection.
[0061] The support member 140 can be, but is not limited to, a support rod, a stud, etc., and no further restrictions are imposed here.
[0062] In one example, the support member 140 includes a screw and a nut, which are screwed together in the height direction X. Thus, the screwed connection of the nut and screw allows the support member 140 to extend and retract in the height direction X, accommodating different distances between the support bracket 110 and the elevator guide rail assembly 200, enriching the application scenarios of the limit auxiliary mechanism 100.
[0063] In some embodiments, such as Figure 2 as well as Figure 3 As described above, both the first limiting wheel 121 and the second limiting wheel 122 are detachably connected to the support bracket 110. Thus, during the actual installation of the inclined elevator, the first limiting wheel 121 and the second limiting wheel 122 can be disassembled and replaced according to the actual installation dimensions, ensuring that the installation error of the inclined elevator is not too large and guaranteeing the operational safety of the inclined elevator.
[0064] Alternatively, in one embodiment, see back Figure 3 The limiting auxiliary mechanism 100 also includes a bolt assembly 150. Both the first limiting wheel 121 and the second limiting wheel 122 are screwed onto the support bracket 110 via the bolt assembly 150. This threaded connection method helps ensure the detachability of the limiting wheel assembly 120 and the support bracket 110 while also achieving self-locking between them to improve connection stability.
[0065] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0066] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0067] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0068] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0069] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0071] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
