Description

[Technical Field]

[0001] The present invention relates to an object moving device that raises and lowers a moving member to which an object to be moved is attached. [Background technology]

[0002] 2. Description of the Related Art Conventionally, a window regulator that raises and lowers a window glass of a vehicle has been known as an object moving device that raises and lowers a moving member.

[0003] For example, Patent Document 1 discloses a window regulator that includes a guide rail that guides a carrier plate, which is a movable member that holds the window glass, so that it can move up and down, and a drive mechanism that reciprocates a cable connected to the carrier plate. A buffer member is provided at the lower end of the carrier plate, and a receiving portion is provided in the housing of the drive mechanism that abuts against the buffer member when the carrier plate descends to restrict the descent of the carrier plate. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] WO2012 / 002093 publication

[0005] In an automobile window regulator, the guide rail is curved so that it is convex toward the outside of the vehicle, and the carrier plate sliding on the guide rail is pulled down by the cable to the lower end position, and when the buffer member of the carrier plate abuts against the receiving portion, the buffer member of the carrier plate receives a rotational moment in a direction away from the guide rail. Therefore, if a force toward the lower end continues to be applied to the carrier plate even after the buffer member abuts against the receiving portion, or if the abutment between the buffer member and the receiving portion is repeated, there is a risk that the above rotational moment will cause the buffer member to fall off the carrier plate.

[0006] An object of the present invention is to provide an object moving device that can prevent the buffer member from falling off the moving member due to contact between the buffer member and a receiving portion. Summary of the Invention [Means for solving the problem]

[0007] An object moving device according to one aspect of the present invention comprises a drive unit, a cable that is wound and unwound by the drive unit, a moving member to which an object to be moved is attached and which moves up and down together with the object to be moved by winding and unwinding the cable, a guide rail that slidably engages with the moving member, is capable of guiding the movement of the moving member, and extends in the direction of movement of the object to be moved, a buffer member provided on the moving member, and a receiving portion that is attached to the guide rail and abuts against the buffer member to restrict the descent of the moving member, and the receiving portion has a processed portion at least at the portion that abuts against the buffer member to increase the frictional force between the receiving portion and the buffer member. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide an object moving device that can prevent the buffer member from falling off the moving member due to contact between the buffer member and the receiving portion. [Brief explanation of the drawings]

[Figure 6] 10 is an example of a perspective view of the periphery of a moving member included in an object moving device according to a modified example, viewed from above on the front side. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] An embodiment of the present invention will now be described with reference to the drawings. The object moving device according to this embodiment is attached to a door of a vehicle, for example, and is used as a window regulator for raising and lowering an object to be moved (for example, a window glass of the vehicle).

[0011] (Overview of the object moving device) FIG. 1 is an example of a perspective view of a general object moving device 1. In this specification, directions are defined assuming that the object moving device 1 shown in FIG. 1 is viewed from above the front side. Furthermore, the left side when viewed from the front side is defined as the left side, and the right side when viewed from the front side is defined as the right side. The same definitions of directions apply to FIGS. 2 to 6 described below.

[0012] As shown in FIG. 1, the object moving device 1 mainly comprises a drive unit 2, a movable member 10 that can move in the vertical direction, a guide rail 5 composed of a substantially rectangular plate-like member having a predetermined length in the vertical direction, an inner cable 6 that moves the movable member 10 in the vertical direction using the drive unit 2, a cable guide 7 that regulates the routing path of the inner cable 6 so that it follows the guide rail 5, a direction change member 8 provided at the upper end of the guide rail 5, a bracket 9, and a stopper 30.

[0013] The drive unit 2 is attached to the lower end of the guide rail 5 and is positioned below the lower limit position of the moving member 10. The drive unit 2 includes, for example, a drum (not shown) that winds and feeds the inner cable 6, a motor 3 that drives the drum, and a housing 4 for accommodating a reducer (not shown) such as a worm gear reducer that is connected to the motor 3. In the object moving device 1 shown in FIG. 1, the drive unit 2 is attached to the lower end of the guide rail 5, but the position of the drive unit is not limited thereto. The drive unit may be provided in the center of the guide rail or elsewhere, or may be configured as a separate unit from the guide rail. The "drive unit 2" described above corresponds to the "drive section" of the present invention.

[0014] The moving member 10 is disposed opposite one surface of the guide rail 5 and is engaged with the guide rail 5 so as to be slidable along the guide rail 5 extending in the vertical direction. The vertical movement of the moving member 10 is guided by the guide rail 5. Although not shown in detail, the moving member 10 is provided with a cable end connecting portion for attaching an end of the inner cable 6. The moving member 10 also has two fixing holes 12 formed therein for fixing, for example, a vehicle window glass (not shown) with screws or the like. The moving member 10 is integrally molded from, for example, a synthetic resin, but the material is not limited to synthetic resin. The material of the moving member 10 may be metal, or a combination of metal and synthetic resin, or the like.

[0015] The guide rail 5 is a thin metal plate such as a galvanized steel plate, and is curved up and down like an arch. A window glass, for example, fixed to the fixing hole 12 of the moving member 10 moves up and down along the curved trajectory. A cable guide 7 is also attached to the guide rail 5.

[0016] The inner cable 6 moves the movable member 10 up and down by the drive device 2, and has one end wound around a drum (not shown) and the other end connected to the movable member 10. When not restricted by the cable guide 7, the inner cable 6 is routed in a straight line so as to follow the shortest distance between the direction-changing member 8 provided at the upper end of the guide rail 5 and the above-mentioned drum (not shown) provided at the lower end of the guide rail 5. The above-mentioned "inner cable 6" corresponds to the "cable" of the present invention.

[0017] As described above, the cable guide 7 is attached to the guide rail 5, and has the function of suppressing abnormal noise caused by vibration of the inner cable 6. At least a portion of the cable guide 7 is always in contact with the inner cable 6, and is configured so that the inner cable 6 slides when the moving member 10 moves up and down.

[0018] The direction-changing member 8 functions as a member for changing the moving direction of the inner cable 6. This direction-changing member is not particularly limited as long as it is a member such as a pulley or a cable guide that can change the routing direction by winding the inner cable around it.

[0019] The bracket 9 is a member for attaching the object movement device 1 to another member (for example, a vehicle door).

[0020] The stopper 30 restricts the downward movement of the movable member 10 in order to stop the movable member 10 at the lowest limit position. The stopper 30 is a member that comes into contact with the buffer member 20 (described later) at the lowest limit position where the movement of the movable member 10 is to be stopped when the movable member 10 moves downward, and is provided on the guide rail 5 below the movable member 10.

[0021] The buffer member 20 and the stopper 30 can both be made of, for example, POM (polyacetal), which has excellent abrasion resistance.

[0022] (Details of the cushioning material and stopper) Next, the buffer member 20 and the stopper 30 will be described in detail.

[0023] FIG. 2 is an example of a perspective view of the movable member 10 as viewed from below on the front side. The surface of the movable member 10 opposite the surface facing the guide rail 5 (see FIG. 1) is defined as the front side of the movable member 10. As shown in FIG. 2, the cushioning member 20 has a generally triangular prism-shaped abutment portion 22 at the tip of its lower side. The cushioning member 20 has a cylindrical main body portion 24 extending in the front-rear direction above the abutment portion 22. Although it is difficult to see in FIG. 2, the main body portion 24 is longer in the front-rear direction than the abutment portion 22 and protrudes further rearward than the rear end of the abutment portion 22 (see FIG. 4 described below). The main body portion 24 has an engagement groove 26 (see FIG. 4 described below) midway in the front-rear direction that engages with the second anti-detachment claw 18 described below.

[0024] The moving member 10 has a fitting portion 14 at its lower end into which the buffer member 20 is fitted. This fitting portion 14 opens downward. The main body 24 of the buffer member 20 is inserted into this fitting portion 14 from the front side.

[0025] The movable member 10 includes a first anti-slip claw 16 and a second anti-slip claw 18 that function to prevent the buffer member 20 from slipping out forward. The first anti-slip claw 16 protrudes downward on the front side of the fitting portion 14 and restricts the movement of the buffer member 20 forward, thereby preventing the buffer member 20 from slipping out of the fitting portion 14, i.e., preventing the buffer member 20 from falling out. As described above, the second anti-slip claw 18 engages with the engagement groove 26 of the buffer member 20 (see FIG. 4 described below) to prevent the buffer member 20 from slipping out of the fitting portion 14, i.e., preventing the buffer member 20 from falling out.

[0026] FIG. 3 is an example of a perspective view of the periphery of the moving member 10 as viewed from above on the front side. As shown in FIG. 3, the stopper 30 includes a receiving portion 31 that abuts against the buffer member 20. This receiving portion 31 corresponds to the entire upper surface of the stopper 30. The receiving portion 31 has a base portion 32 on the guide rail 5 side and an inclined portion 34 on the front side of the base 32. The base portion 32 is approximately perpendicular to the guide rail 5. The inclined portion 34 is inclined upward and forward at an angle of approximately 10° to 20° with respect to a plane perpendicular to the guide rail 5, i.e., the plane of the base portion 32. In other words, the inclined portion 34 is inclined upward as it moves away from the guide rail 5 in the forward direction.

[0027] In the object movement device 1 configured as described above, when the motor 3 (see FIG. 1) rotates in one direction, the drum (not shown) rotates via the reducer, the inner cable 6 is driven in a circulating manner, and the moving member 10 rises. When the moving member 10 rises, a window glass of a vehicle, for example, fixed to the fixing hole 12 of the moving member 10, rises. On the other hand, when the motor 3 rotates in the other direction, the inner cable 6 is driven in a circulating manner in the opposite direction, and the moving member 10 falls. When the moving member 10 falls, for example, the window glass of the vehicle falls. When the moving member 10 is at its lowest position, the buffer member 20 comes into contact with the stopper 30, and the descent of the moving member 10 is stopped.

[0028] (Problems that may occur when the buffer member and stopper come into contact) Next, problems that may arise when the moving member 10 moves downward and the buffer member 20 and the stopper 30 come into contact will be described with reference to Figures 4(A) to (C). Figures 4(A) to (C) are examples of schematic diagrams showing the side surfaces of the buffer member 20 and the stopper 30 as viewed from the left side, with (A) a diagram showing the state when the buffer member 20 and the stopper 30 come into contact, (B) a diagram showing the state when the buffer member 20 is removed from the fitting portion 14, and (C) a diagram showing the state after the buffer member 20 has come out of the fitting portion 14.

[0029] When the moving member 10 (see FIGS. 1 to 3) moves downward, the buffer member 20 and the stopper 30 come into contact with each other, as shown in FIG. 4(A). At this time, the contact portion 22 of the buffer member 20 comes into contact with the inclined portion 34 of the stopper 30. A force F acts on the moving member 10 in a downward rearward direction due to the cable pulling angle of the inner cable 6 (see FIG. 1 or 3). As a result, a rotational moment M acts on the buffer member 20, moving the contact portion 22 forward (i.e., in a direction away from the guide rail 5). The direction in which this rotational moment M acts is counterclockwise in FIG. 4.

[0030] When the cushioning member 20 and the stopper 30 repeatedly come into contact with each other, the rotational moment M described above repeatedly applies a load to the engagement groove 26 that engages with the second fall-off prevention claw 18 and to the abutment portion 22. As a result, as shown in FIG. 4(B), the first fall-off prevention claw 16 bites into the main body portion 24 of the cushioning member 20, and the second fall-off prevention claw 18 applies a force to the wall 27 at the rear end of the engagement groove 26. At this time, the abutment portion 22 of the cushioning member 20 tries to climb over the inclined portion 34.

[0031] If the cushioning member 20 and the stopper 30 are repeatedly brought into contact with each other after the cushioning member 20 and the stopper 30 reach the state shown in Figure 4(B), the contact portion 22 of the cushioning member 20 may go far beyond the inclined portion 34, as shown in Figure 4(C), and the cushioning member 20 may fall off from the fitting portion 14.

[0032] (Prevents shock-absorbing materials from falling off) Next, the object moving device 1A according to this embodiment will be described with reference to Fig. 5. Fig. 5 is an example of a perspective view of the periphery of a moving member 10 provided in the object moving device 1A according to this embodiment, viewed from above on the front side. Note that, among the various components provided in the object moving device 1A, the same components as those provided in the object moving device 1 described above will be assigned the same reference numerals as in Figs. 1 to 4.

[0033] Similar to a general object moving device 1, the object moving device 1A according to this embodiment mainly includes a drive unit 2 (see FIG. 1), a moving member 10, a guide rail 5, an inner cable 6, a cable guide 7, a direction changing member 8 (see FIG. 1), and a bracket 9 (see FIG. 1). The drive unit 2, moving member 10, guide rail 5, inner cable 6, cable guide 7, direction changing member 8, and bracket 9 included in the object moving device 1A are the same as the drive unit 2, moving member 10, guide rail 5, inner cable 6, cable guide 7, direction changing member 8, and bracket 9 included in the object moving device 1 described above, and therefore description thereof will be omitted.

[0034] Moreover, the object moving device 1A includes a stopper 30A instead of the stopper 30 that the object moving device 1 includes.

[0035] Like the stopper 30, the stopper 30A is a member that comes into contact with the buffer member 20 when the moving member 10 moves downward, and is provided on the guide rail 5 below the moving member 10. Also, like the stopper 30, the stopper 30A is made of, for example, POM, which has excellent abrasion resistance, but is not limited to this, and for example, an elastic member that can absorb the impact when the buffer member 20 comes into contact with the stopper 30A may be used as the material.

[0036] Like stopper 30, stopper 30A has a base 32A that is substantially perpendicular to guide rail 5, and an inclined portion 34A that is inclined upward and forward at an angle of approximately 10° to 20° relative to the surface of base 32A.

[0037] Unlike stopper 30, stopper 30A has a high-frictional force portion 36A on inclined portion 34A. In this embodiment, high-frictional force portion 36A is provided only on a portion of the front side of inclined portion 34A, but high-frictional force portion 36A may be provided over the entire inclined portion 34A.

[0038] The high-friction portion 36A is a portion where the frictional force between the high-friction portion 36A and the buffer member 20 is higher than that of other portions of the receiving portion 31A. In this embodiment, the high-friction portion 36A is, for example, a portion where a groove shape is formed along the width direction perpendicular to the extension direction of the guide rail 5, i.e., the left-right direction. The groove-shaped convex portion extends continuously and without interruption along the left-right direction. When the groove-shaped convex portion extends continuously along the left-right direction, it is possible to increase the grip force of the high-friction portion 36A, i.e., the frictional force that resists the rotational moment M, compared to when the convex portion is interrupted along the left-right direction. In addition, the cross section of the convex portion when cut in the front-rear direction can have various shapes, such as a square, a triangle with an apex angle, or an arc shape without a corner at the apex. Furthermore, when a convex portion is formed, a groove portion is formed as a concave portion. If the angle between this groove portion and the wall of the convex portion is 45 to 135 degrees (including the lower limit and the upper limit), and if the cross-sectional shape of the groove is an arc, the angle between the tangent to the apex of the arc and the wall of the convex portion is 45 to 135 degrees (including the lower limit and the upper limit), preferably, if the angle between the groove portion and the wall of the convex portion is 90 to 135 degrees (including the lower limit and the upper limit), and if the cross-sectional shape of the groove is an arc, the angle between the tangent to the apex of the arc and the wall of the convex portion is 90 to 135 degrees (including the lower limit and the upper limit), it is possible to further increase the frictional force between the high-frictional force portion 36A and the buffer member 20.

[0039] When the buffer member 20 and the stopper 30A come into contact with each other, the contact portion 22 (see FIGS. 2 and 4) comes into contact with the high-friction portion 36A of the inclined portion 34A. Therefore, even if the rotational moment M (see FIG. 4) described above acts on the buffer member 20, the relatively high frictional force of the high-friction portion 36A prevents the first retaining claw 16 (see FIG. 4B) from biting into the main body 24 of the buffer member 20. This also reduces the force acting on the wall 27 at the rear end of the engagement groove 26 (see FIG. 4B). As a result, the contact portion 22 of the buffer member 20 is prevented from climbing over the inclined portion 34A. Therefore, even if the buffer member 20 and the stopper 30A come into contact with each other repeatedly, the buffer member 20 is prevented from falling off the fitting portion 14 (see FIGS. 3 and 4).

[0040] Furthermore, it is preferable that the high-frictional-force portion 36A has a plurality of parallel protrusions extending in the left-right direction. The greater the number of protrusions, the greater the frictional force that can counteract the rotational moment M.

[0041] (Variation) While the above embodiment has been described as an example of the present invention, the present invention is not limited to the above embodiment and various modifications are possible within the scope of the claims. For example, the stopper 30A described above can be changed to a stopper 30B shown in FIG. 6.

[0042] 6 is an example of a perspective view of the periphery of the moving member 10 provided in an object moving device 1B according to a modified example, viewed from above on the front side. The object moving device 1B is provided with a stopper 30B instead of the stopper 30A provided in the object moving device 1A. Note that, except for the stopper 30B, the various components provided in the object moving device 1B are the same as the various components provided in the object moving device 1A. Therefore, the following will describe the stopper 30B, and descriptions of the various components other than the stopper 30B will be omitted.

[0043] The stopper 30B is the same as the stopper 30A except for the shape of the convex portion of the high-friction portion 36B. Specifically, the stopper 30B is a member that comes into contact with the buffer member 20 when the moving member 10 moves downward, and is provided on the guide rail 5 below the moving member 10. Like the stopper 30A, the stopper 30B is made of, for example, POM, which has excellent abrasion resistance, but is not limited to this. Like the stopper 30A, the stopper 30B may also be made of, for example, an elastic member.

[0044] Like stopper 30A, stopper 30B has a base 32B that is substantially perpendicular to guide rail 5, and an inclined portion 34B that is inclined upward and forward at an angle of approximately 10° to 20° relative to the surface of base 32B.

[0045] The stopper 30B includes a high-friction portion 36B on the inclined portion 34B, which has a protrusion formed in the shape of, for example, a triangular or square pyramid with a corner at its apex. Similar to the high-friction portion 36A, the high-friction portion 36B is a portion where the frictional force between the high-friction portion 36B and the buffer member 20 is higher than that of other portions of the receiving portion 31B. In this modification, the high-friction portion 36B is formed only on a portion of the front side of the inclined portion 34B, but the high-friction portion 36B may be formed over the entire inclined portion 34B. The apex angle of the triangular or square pyramidal protrusion formed on the high-friction portion 36B is preferably in the range of 10 to 90 degrees (including the lower and upper limits).

[0046] In this way, even when stopper 30A is replaced with stopper 30B, it is possible to increase the gripping force of high friction force portion 36B, i.e., the friction force that resists the above-mentioned rotational moment M, with a simple configuration. Therefore, even if cushioning member 20 and stopper 30B are repeatedly brought into contact with each other, it is possible to prevent cushioning member 20 from falling off fitting portion 14 (see FIGS. 3 and 4).

[0047] In the above-described embodiment and modified examples, the high-frictional force portions 36A and 36B are convex portions formed on the inclined portions 34A and 34B, respectively. That is, these convex portions are formed from the material of the stoppers 30A and 30B. However, the high-frictional force portions 36A and 36B are not necessarily limited to being formed from the material of the stoppers 30A and 30B. For example, a material that enhances grip strength may be attached to the inclined portions 34A and 34B as long as it can resist the rotational moment M.

[0048] In the above-described embodiment, the high-friction force portion 36A is a groove-shaped portion, and in the above-described modified example, the high-friction force portion 36B is a triangular or square pyramid-shaped portion. However, the shape of the high-friction force portion is not limited to a convex portion, a groove, a triangular or square pyramid, and may be a cone, a hemisphere, or the like, as long as the frictional force between the high-friction force portion and the cushioning member 20 is higher than that of other portions of the receiving portion (portions of the receiving portion that are not the high-friction force portions). Furthermore, within the area where the high-friction force portion is provided, shapes such as convex portions, grooves, triangular or square pyramids, cones, and hemispheres may be arranged in a linear or wavy pattern, or may be arranged randomly.

[0049] Furthermore, in the above-described embodiment, the object moving device 1A is provided with a stopper 30A below the movable member 10, which abuts against the buffer member 20 when the movable member 10 moves downward. Furthermore, in the above-described modified example, the object moving device 1B is provided with a stopper 30B below the movable member 10, which abuts against the buffer member 20 when the movable member 10 moves downward. However, it is not essential that the object moving device 1A be provided with the stopper 30A below the movable member 10, and it is not essential that the object moving device 1B be provided with the stopper 30B below the movable member 10. For example, when the movable member 10 moves downward, the buffer member 20 provided at the lower end of the movable member 10 may abut against a member attached to the guide rail 5. The member attached to the guide rail 5 is, for example, the drive device 2 (a drum (not shown), a housing 4, etc.). If the cable guide 7 can be provided at the lowest position of the movable member 10, the cable guide 7 is also included in the member attached to the above-described guide rail 5. In this way, when the buffer member 20 is made to abut against a member attached to the guide rail 5, it is preferable to provide the member against which the buffer member 20 abuts with a receiving portion having a high friction force portion equivalent to the above-mentioned high friction force portion 36A or high friction force portion 36B.

[0050] Furthermore, in the above-described embodiment and modified examples, the movable member 10 has, at its lower end, a fitting portion 14 into which the buffer member 20 is fitted. However, the fitting portion 14 is not necessarily limited to being provided at the lower end of the movable member 10. For example, if, when the movable member 10 moves downward, the buffer member 20 comes into contact with a portion above the lower end of the movable member 10 (for example, a portion to the right of the fitting portion 14 shown in FIG. 2), the fitting portion 14 may be provided at this portion.

[0051] Although the embodiments and modifications have been described above, the present invention is not limited to the above-described embodiments and modifications, and various modifications are possible within the scope of the claims. Note that the above-described embodiments and modifications mainly describe the invention having the following configuration.
