Description

[Technical Field]

[0001] The present invention relates to a sunshade device. [Background technology]

[0002] Patent Document 1 below discloses this type of sunshade device. This sunshade device has end members on both ends of a frame attached to the sunshade, and the movement of these end members in the sliding direction is guided by guide members. The guide members also have concave and convex portions that can engage with the end members and flat portions that can abut against the end members. When the end members of the frame engage with the concave and convex portions and abut against the flat portions, the frame enters a locked state, locking the operation of the frame and stopping the sunshade at any extended position. In contrast, when the engagement between the end members of the frame and the concave and convex portions is released, the frame enters an unlocked state, allowing operation of the frame, and the sunshade is rolled up.

[0003] [Patent Document 1] Japanese Patent Publication No. 2019-172043 Summary of the Invention [Problem to be solved by the invention]

[0004] With the above-described sunshade device, it is possible that the end member of the frame may slide along the flat portion when switching from the unlocked state to the locked state or after switching to the locked state. In this case, the end member of the frame is allowed to move in the sliding direction, which may cause a problem that the sunshade cannot be stopped and held in the desired position as intended by the user. Furthermore, the sliding of the end member of the frame along the flat portion may cause vibrations.

[0005] The present invention has been made in view of the above-mentioned problems, and aims to provide a sunshade device that can stop and hold a sunshade at a desired position. [Means for solving the problem]

[0006] One aspect of the present invention is A sunshade device mounted on a vehicle, a sunshade for covering a window portion of the vehicle; a storage section for storing the sunshade in a drawable manner; a biasing portion that biases the sunshade so as to return it to the storage portion; a frame member attached to the sunshade; guide members for guiding frame end portions on both longitudinal sides of the frame member in a sliding direction; Equipped with The frame end has a first engaged portion and a second engaged portion, the guide member has a first wall portion and a second wall portion that face the first engaged portion and the second engaged portion, respectively, and both the first wall portion and the second wall portion are provided with concave-convex engaging portions; the frame end is in an unlocked state slidable in the sliding direction when the first engaged portion is not engaged with the engaging portion of the first wall portion, and when the first engaged portion engages with the engaging portion of the first wall portion, the frame end rotates in the locking direction around the first engaged portion in accordance with the biasing force of the biasing portion, causing the second engaged portion to engage with the engaging portion of the second wall portion and enter a locked state; is located. [Effects of the Invention]

[0007] In the sunshade device of the above aspect, a frame member is attached to a sunshade for covering a vehicle window. A frame end of the frame member is guided in a sliding direction by a guide member. A first engaged portion of the frame end can engage with a concave-convex engaging portion provided on a first wall portion of the guide member, and a second engaged portion of the frame end can engage with a concave-convex engaging portion provided on a second wall portion of the guide member.

[0008] The frame end is in an unlocked state where it can slide in the sliding direction when the first engaged portion is not engaged with the concave-convex engaging portion of the first wall portion. This allows the frame member to be moved in the sliding direction to pull the sunshade out of the storage portion against the biasing force of the biasing portion, or to pull the sunshade back into the storage portion in response to the biasing force of the biasing portion.

[0009] On the other hand, when the first engaged portion engages with the concave-convex engaging portion of the first wall portion, the frame end rotates in the locking direction around the first engaged portion in accordance with the biasing force of the biasing portion. At this time, the frame end enters a locked state as the second engaged portion engages with the concave-convex engaging portion of the second wall portion. In other words, when the frame end is locked, both the first engaged portion and the second engaged portion engage with the concave-convex engaging portion corresponding to the engaged portion. This prevents slippage between the engaged portions and the concave-convex engaging portion when engaging with the concave-convex engaging portion, which could cause the locked state of the frame end to be lost. Therefore, the sunshade can be held in the position where the frame end is locked.

[0010] According to the above-described aspect, it is possible to provide a sunshade device that can stop and hold the sunshade at a desired position. [Brief explanation of the drawings]

[0012] Preferred embodiments of the above aspects are described below.

[0013] In the sunshade device of the above aspect, it is preferable that the guide member is configured so that the first wall portion and the second wall portion are arranged opposite each other, sandwiching the frame end portion of the frame member in the thickness direction of the sunshade.

[0014] According to this sunshade device, the frame end of the frame member can be sandwiched between the first and second wall portions of the guide member from both sides in the thickness direction of the sunshade. This makes it difficult for the locked state of the frame end to be released when the first engaged portion engages with the concave-convex engaging portion of the first wall portion and the second engaged portion engages with the concave-convex engaging portion of the second wall portion.

[0015] In the sunshade device of the above aspect, it is preferable that the engaging portion is formed by alternately repeating concave and convex portions in the sliding direction on each of the first wall portion and the second wall portion of the guide member.

[0016] According to this sunshade device, by providing engagement portions with alternating concave and convex portions in the sliding direction on each of the first and second wall portions of the guide member, the frame end of the frame member can be locked at any position in the sliding direction, thereby making it possible to reliably stop and hold the sunshade at any position.

[0017] In the sunshade device of the above-mentioned aspect, it is preferable that the first engaged portion is provided with a locking claw portion that fits into a recess of the engaging portion of the first wall portion, and the second engaged portion is provided with a flat surface that comes into face-to-face contact with the load-bearing surface of the engaging portion of the second wall portion.

[0018] According to this sunshade device, the first engaged portion's locking claw fits into the recess of the engaging portion of the first wall portion, and the second engaged portion's flat surface abuts against the load-receiving surface of the engaging portion of the second wall portion, thereby locking the frame end. By providing the locking claw on the first engaged portion that engages first, the first engaged portion can be reliably engaged with the recess of the engaging portion of the first wall portion. Then, by abutting the flat surface of the second engaged portion against the load-receiving surface of the engaging portion of the second wall portion, the first engaged portion can be maintained in an engaged state to prevent disengagement of the first engaged portion. At this time, the second engaged portion performs an auxiliary engagement function for the first engaged portion. By providing only a flat surface on the second engaged portion, the structure of both the second engaged portion and the associated engaging portion of the second wall portion can be simplified.

[0019] Hereinafter, specific examples of embodiments of the sunshade device will be described with reference to the drawings.

[0020] In the drawings used in this description, the front of the vehicle is indicated by arrow FR, the upper side of the vehicle is indicated by arrow UP, and the interior of the vehicle is indicated by arrow IN. Unless otherwise specified, the first direction, which is the sliding direction of the frame member, is indicated by arrow X, the second direction, which is the longitudinal direction of the frame member, is indicated by arrow Y, and the third direction, which is the width direction of the frame member and is perpendicular to both the first and second directions, is indicated by arrow Z.

[0021] (Embodiment 1) 1, a sunshade device 101 of the first embodiment is mounted on a vehicle 1. In this embodiment, the sunshade device 101 mounted on a vehicle door 2 provided on the side of the vehicle 1 is exemplified.

[0022] The sunshade device 101 includes a sunshade 10, a storage section 12, a frame member 20, and two guide members 30.

[0023] The sunshade 10 is for covering the window portion 3 of the vehicle door 2. The sunshade 10 is a sheet-like or screen-like shielding member that is light-blocking and flexible, and is configured to be stored in a storage section 12 so that it can be pulled out.

[0024] The storage section 12 is disposed above the window section 3 of the vehicle door 2. A winding section 11 extending in the second direction Y is provided inside the storage section 12. The winding section 11 is supported rotatably about rotation shafts 13a at both ends in the second direction Y. The winding section 11 is also biased by a biasing section (biasing section 13 described below) for pulling the sunshade 10 back into the storage section 12.

[0025] The sunshade 10 is used as a sunshade that can block sunlight from outside the vehicle due to its light-blocking properties. In addition, the sunshade 10 is flexible so that it can be wound around the outer circumferential surface of the winding portion 11.

[0026] As shown in Fig. 4, the storage section 12 is disposed closer to the passenger compartment than the window section 3 of the vehicle door 2. In this embodiment, a spring member is used as the biasing section 13, which constantly elastically biases the winding section 11 in the winding direction. Therefore, when a load in the pulling-out direction X1 that overcomes the elastic biasing force of the spring member is applied to the sunshade 10, the sunshade 10 is pulled out in the pulling-out direction X1. On the other hand, when this load is released, the sunshade 10 is pulled back in the pulling-back direction X2, which is opposite to the pulling-out direction X1, due to the elastic biasing force of the spring member.

[0027] As shown in FIG. 1, the frame member 20 is attached to the front end of the sunshade 10 in the pull-out direction so as to extend in the second direction Y, which is the longitudinal direction. This frame member 20 has enough rigidity to stretch the sunshade 10 in a sheet-like state. This frame member 20 is provided with an operating part 20a that can be held by the user's fingers. Therefore, the user can move the frame member 20 by holding the operating part 20a with their fingers and pulling it down or pushing it up. In this case, the sunshade 10 is a manual shade that can be pulled out or pulled back by manually moving the frame member 20.

[0028] As shown in Fig. 1, the guide members 30 are intended to guide frame ends (frame ends 22, described below) on both sides of the frame member 20 in the second direction Y. The two guide members 30 are arranged parallel to each other and both extend along the first direction X. In Fig. 1, of the two guide members 30, the guide member 30 on the front side in the second direction Y is referred to as guide member 30A, and the guide member 30 on the rear side in the second direction Y is referred to as guide member 30B.

[0029] Here, the manner of use of the sunshade 10 will be described with reference to FIGS.

[0030] 1, when the sunshade 10 is set to the non-shading state P0 without being pulled downward from the storage section 12, the window section 3 cannot be covered from the inside of the vehicle by the sunshade 10, and the sun from outside the vehicle cannot be blocked by the sunshade 10. In this state, the occupants of the vehicle 1 can see the scenery outside the vehicle through the entire window section 3.

[0031] As shown in Fig. 2, the sunshade 10 is set to a first use state P1 by being pulled downward from the non-shading state P0 in Fig. 1. In this first use state P1, only the upper area of the window section 3 is covered from the inside of the vehicle by the sunshade 10, and some of the sunlight from outside the vehicle is blocked by the sunshade 10, which has light-blocking properties. At this time, the occupants of the vehicle 1 can see the scenery outside the vehicle only through the lower area of the window section 3.

[0032] As shown in Figure 3, the sunshade 10 is set to a second use state P2 by being pulled further downward from the first use state P1. In this second use state P2, the entire window portion 3 is covered from the inside of the vehicle by the sunshade 10, and all sunlight from outside the vehicle is blocked by the sunshade 10, which has light-blocking properties. At this time, the occupants of the vehicle 1 cannot see the scenery outside the vehicle through the window portion 3.

[0033] The sunshade device 101 configured as described above has a multi-stage stop structure that can stop the sunshade 10 in multiple stages. The sunshade device 101 is also configured so that the storage section 12 is located above the window section 3 and the sunshade 10 is pulled down from above the window section 3 when in use. This has the advantage that occupants can enjoy the scenery while stopping the sunshade 10 midway depending on the amount of sunlight coming from outside the vehicle. In contrast, a structure in which the sunshade is pulled up from below the window section 3 has the disadvantage that it is difficult to adjust the amount of sunlight with the sunshade, and for example, pulling the sunshade up too far can impair visibility of the scenery outside the vehicle.

[0034] (Frame member structure) 5, the frame member 20 has a main body portion 21 extending with the second direction Y as its longitudinal direction, and frame end portions 22 provided on both sides of the main body portion 21 in the second direction Y. As shown in an enlarged view of area A in FIG. 5, the frame end portion 22 has a first engaged portion 23, a second engaged portion 24, a connecting shaft portion 25, and a movement restricting portion 26.

[0035] The first engaged portion 23 and the second engaged portion 24 are arranged on either side of the connecting shaft portion 25 on a plane defined by the first direction X and the third direction Z. The first engaged portion 23 is provided with a convex locking claw portion 23a. The second engaged portion 24 is provided with a flat surface 24a. The operation restricting portion 26 is provided on the frame end portion 22 outside the engaged portions 23, 24 in the second direction Y.

[0036] (Structure of guide member) As shown in Fig. 6, guide member 30A has a first wall portion 31, a second wall portion 33, and a third wall portion 36. As shown in Fig. 7, guide member 30B has, similarly to guide member 30A, a first wall portion 31, a second wall portion 33, and a third wall portion 36. In this embodiment, a symmetrical structure in which guide member 30A and guide member 30B are symmetrical with respect to the second direction Y is illustrated.

[0037] As shown in Figures 6 and 7, the first wall portion 31 and the second wall portion 33 both extend with the third direction Z as their thickness direction and the first direction X as their longitudinal direction. The first wall portion 31 and the second wall portion 33 are spaced apart in the third direction Z across the storage space 35 and are arranged facing each other so as to be generally parallel. The first wall portion 31 is located on the outer side of the vehicle than the second wall portion 33. As a result, the guide members 30A, 30B are configured so that the first wall portion 31 and the second wall portion 33 are arranged facing each other with the frame end portion 22 of the frame member 20 sandwiched between them in the third direction Z, which is the thickness direction of the sunshade 10. The first wall portion 31 is provided with a concave-convex engaging portion 32 facing the storage space 35. Similarly, the second wall portion 33 is provided with a concave-convex engaging portion 34 facing the storage space 35.

[0038] The third wall portion 36 connects the first wall portion 31 and the second wall portion 33. The third wall portion 36 is a convex wall portion that protrudes outward in the second direction Y from the first wall portion 31 and the second wall portion 33, and defines an accommodation space 37. The accommodation space 37 has a dimension in the third direction that is smaller than that of the accommodation space 35. The accommodation space 35 accommodates the first engaged portion 23 and the second engaged portion 24 of the frame end portion 22 of the frame member 20. Meanwhile, the accommodation space 37 accommodates the movement restricting portion 26 of the frame end portion 22 of the frame member 20.

[0039] 8, in the guide member 30A, the engagement portion 32 of the first wall portion 31 is formed by alternately providing engagement teeth 32a, which are convex portions, and gaps 32b, which are concave portions, in the first direction X. Each engagement tooth 32a has a first inclined surface 32c on the upper side and a second inclined surface 32d on the lower side, and is formed so that the inclination of the first inclined surface 32c is greater than that of the second inclined surface 32d when viewed from the second direction Y. In other words, the engagement portion 34 is formed so as to have a tooth-like shape when viewed from the second direction Y.

[0040] In contrast, the engaging portion 34 of the second wall portion 33 has convex portions 34a and concave portions 34b alternately arranged in the first direction X. In addition, an inclined surface 34c, which is a load-bearing surface, is formed between the convex portions 34a and the concave portions 34b. In other words, the engaging portion 34 is formed so as to have a wavy shape when viewed from the second direction Y.

[0041] Although details will be described later, when the first engaged portion 23 of the frame end 22 is not engaged with the engaging portion 32 of the first wall portion 31, the frame member 20 is in an unlocked state in which the frame end 22 can slide in the first direction X. In contrast, when the first engaged portion 23 of the frame end 22 is engaged with the engaging portion 32 of the first wall portion 31 and the second engaged portion 24 of the frame end 22 is engaged with the engaging portion 34 of the second wall portion 33, the frame member 20 is in a locked state in which the frame end 22 cannot slide in the first direction X.

[0042] Guide member 30A is configured so that groove depth d1 of the concave-convex grooves in engagement portion 32 of first wall portion 31 exceeds groove depth d2 of the concave-convex grooves in engagement portion 34 of second wall portion 33. Although not specifically shown, this configuration also applies to guide member 30B.

[0043] As shown in FIG. 8 , the third wall portion 36 accommodates the movement restricting portion 26 in the accommodation space 37 so that the movement restricting portion 26 is slidable in the first direction X and rotatable on a plane defined by the first direction X and the third direction Z. The third wall portion 36 is provided with two sliding contact surfaces 36a, 36b that face each other in the third direction Z. The movement restricting portion 26 is disposed at a first position Q1 (see the position indicated by the two-dot chain line in FIG. 8 ) where it does not abut against the sliding contact surfaces 36a, 36b when the frame end portion 22 of the frame member 20 is in the locked state. In contrast, the movement restricting portion 26 is disposed at a second position Q2 (see the position indicated by the solid line in FIG. 8 ) where it is in sliding contact with the sliding contact surfaces 36a, 36b when the frame end portion 22 of the frame member 20 is in the unlocked state. The movement restricting portion 26 is configured to allow the frame end portion 22 to slide in the first direction X at the second position Q2, but restrict movement in the unlocking direction (an unlocking direction D2 described below).

[0044] The movement restricting portion 26 has a first restricting surface 26a and a second restricting surface 26b. The first restricting surface 26a and the second restricting surface 26b are formed to be generally parallel. The first sliding contact surface 36a of the third wall portion 36 faces the first restricting surface 26a of the movement restricting portion 26 so as to be able to slide thereon. The second sliding contact surface 36b of the third wall portion 36 faces the second restricting surface 26b of the movement restricting portion 26 so as to be able to slide thereon. The first sliding contact surface 36a and the second sliding contact surface 36b are formed to be generally parallel. In this case, the dimension from the first restricting surface 26a to the second restricting surface 26b of the movement restricting portion 26 is set to be the same as or slightly shorter than the distance between the first sliding contact surface 36a and the second sliding contact surface 36b.

[0045] The movement restricting unit 26 is configured such that, at the first position Q1, the first restricting surface 26a and the first sliding contact surface 36a are released from contact with each other, and the second restricting surface 26b and the second sliding contact surface 36b are released from contact with each other. When the movement restricting unit 26 rotates from the first position Q1 to the second position Q2, the first restricting surface 26a comes into sliding contact with the sliding contact surface 36a, and the second restricting surface 26b comes into sliding contact with the sliding contact surface 36b. At this time, the first restricting surface 26a and the sliding contact surface 36a are disposed substantially parallel to each other, and the second restricting surface 26b and the sliding contact surface 36b are disposed substantially parallel to each other. This allows the movement restricting unit 26 to slide between, for example, the second position Q2 and the third position Q3 (see the positions indicated by the two-dot chain line in FIG. 8 ) while maintaining the same posture in the accommodation space 37.

[0046] As shown in FIG. 9, in guide members 30A and 30B, first wall portion 31 faces first engaged portion 23 provided on frame end portion 22 of frame member 20, and second wall portion 33 faces second engaged portion 24 provided on frame end portion 22 of frame member 20. Therefore, first engaged portion 23 can engage with engaging portion 32 provided on first wall portion 31. At this time, first engaged portion 23 is configured to engage with engaging portion 32 by fitting its locking claw portion 23a (see FIG. 5) into gap 32b (see FIG. 8), which is a recess of engaging portion 32. Also, second engaged portion 24 can engage with engaging portion 34 provided on second wall portion 33. At this time, second engaged portion 24 is configured to engage with engaging portion 34 by having its flat surface 24a (see FIG. 5) come into surface contact with inclined surface 34c (see FIG. 8), which is a load-bearing surface of engaging portion 34.

[0047] As shown in FIG. 9 , the frame end 22 has a stepped shape. In this embodiment, when the frame end 22 is viewed from the first direction X, the stepped shape has a smaller dimension in the direction intersecting the second direction Y (third direction Z) at the outer side in the second direction Y. When the frame end 22 is viewed from the first direction X, the dimension w1 in the third direction Z of the movement restricting portion 26 located on the outer side in the second direction Y is smaller than the dimension w2 in the third direction Z of the portion where the engaged portions 23, 24 are provided. In this manner, the frame end 22 forms a stepped shape with one step by utilizing the engaged portions 23, 24 and the movement restricting portion 26. Correspondingly, the guide member 30 is provided with a stepped groove into which the stepped frame end 22 fits. This stepped groove is formed by the accommodation space 35 and the accommodation space 37.

[0048] Fitting the stepped frame end portion 22 into the stepped groove of the guide member 30 is effective in restricting the movement of the frame member 20 so as to prevent, for example, the following phenomena from occurring: In Fig. 9, the frame member 20 is less likely to be displaced in the first direction X relative to the guide member 30, the frame member 20 is less likely to rotate on a plane defined by the second direction Y and the third direction Z, or the frame member 20 is less likely to tilt obliquely due to differences in height in the first direction X between the two frame end portions 22.

[0049] Next, the movement of the frame end portion 22 of the frame member 20 relative to the guide member 30A will be described with reference to Figures 4, 5, 8, 10, 11, etc. Although not specifically shown, the movement of the frame end portion 22 of the frame member 20 relative to the guide member 30B is similar.

[0050] When using the sunshade 10, the user operates the operating portion 20a (see FIG. 5) of the frame member 20 so as to pull out the sunshade 10 in the pulling-out direction X1 (see FIG. 4). Then, as shown in FIG. 10, the user moves the frame member 20 so as to fit the locking claw portion 23a of the first engaged portion 23 of the frame end portion 22 into the gap 32b of the engaging portion 32. As a result, the frame end portion 22 is positioned at the engaging position R0 where the first engaged portion 23 is engaged with the engaging portion 32.

[0051] Thereafter, when the first engaged portion 23 engages with the engaging portion 32, the frame end portion 22 rotates in the locking direction D1 around the locking claw portion 23a of the first engaged portion 23 in accordance with the biasing force of the biasing portion 13 (see FIG. 4). This causes the second engaged portion 24 to engage with the engaging portion 34. Therefore, the frame end portion 22 is placed in the lock position R1 and in a locked state, allowing the sunshade 10 to be stopped and held at a desired position. At this time, by engaging both the first engaged portion 23 and the second engaged portion 24 with the uneven engaging portions 32, 34, it is more effective in maintaining the locked state of the frame end portion 22 than, for example, when one of the two engaging portions 32, 34 is flat.

[0052] When the frame end 22 reaches the lock position R1, the flat surface 24a of the second engaged portion 24 comes into face-to-face contact with the inclined surface 34c of the engaging portion 34. Therefore, the flat surface 24a comes into face-to-face contact with the inclined surface 34c, thereby maintaining the engaged state between the first engaged portion 23 and the engaging portion 32.

[0053] When the frame end 22 is in the locked position R1, the movement restricting portion 26 is positioned at the first position Q1. When the movement restricting portion 26 is positioned at the first position Q1, the first restriction surface 26a is released from contact with the first sliding contact surface 36a, and the second restriction surface 26b is released from contact with the second sliding contact surface 36b (see FIG. 8). Therefore, the movement of the frame end 22 from the locked position R1 in the unlocking direction D2 is not restricted by the movement restricting portion 26. Therefore, the frame end 22 in the locked position R1 can be moved in the unlocking direction D2.

[0054] 11, when a user moves the sunshade 10, the user operates the operating portion 20a of the frame member 20 to move the frame end portion 22 from the locked position R1 in the unlocked direction D2. At this time, the first engaged portion 23 moves in the unlocked direction D2 to disengage from the engaging portion 32, and the second engaged portion 24 moves in the unlocked direction D2 to disengage from the engaging portion 34. As a result, the frame end portion 22 is placed in the unlocked position R2 and enters an unlocked state, allowing the sunshade 10 to be freely moved in the first direction X.

[0055] When the frame end 22 is in the unlocked position R2, the movement restricting portion 26 is positioned at the second position Q2. When the movement restricting portion 26 is positioned at the second position Q2, the first restriction surface 26a and the first sliding contact surface 36a are in sliding contact with each other, and the second restriction surface 26b and the second sliding contact surface 36b are in sliding contact with each other (see FIG. 8). Therefore, the movement of the frame end 22 from the unlocked position R2 in the unlocking direction D2 is restricted by the movement restricting portion 26. Therefore, the frame end 22 in the unlocked position R2 is prevented from moving in the unlocking direction D2.

[0056] According to the above-described first embodiment, the following effects can be obtained.

[0057] In the sunshade device 101 of the first embodiment, a frame member 20 is attached to a sunshade 10 for covering a window portion 3 of a vehicle door 2. A frame end portion 22 of the frame member 20 is guided in a first direction X by a guide member 30. In the frame member 20, a first engaged portion 23 of the frame end portion 22 is engageable with a concave-convex engaging portion 32 provided on a first wall portion 31 of the guide member 30, and a second engaged portion 24 of the frame end portion 22 is engageable with a concave-convex engaging portion 34 provided on a second wall portion 33 of the guide member 30.

[0058] The frame end 22 is in an unlocked state where it can slide in the first direction X when the first engaged portion 23 is not engaged with the concave-convex engaging portion 32 of the first wall portion 31. Therefore, by moving the frame member 20 in the first direction X, the sunshade 10 can be pulled out of the storage portion 12 against the biasing force of the biasing portion 13, or the sunshade 10 can be pulled back into the storage portion 12 in accordance with the biasing force of the biasing portion 13.

[0059] On the other hand, when the first engaged portion 23 engages with the concave-convex engaging portion 32 of the first wall portion 31, the frame end portion 22 rotates in the locking direction D1 around the first engaged portion 23 in accordance with the biasing force of the biasing portion 13. At this time, the frame end portion 22 enters a locked state as the second engaged portion 24 engages with the concave-convex engaging portion 34 of the second wall portion 33. That is, when the frame end portion 22 is in the locked state, both the first engaged portion 23 and the second engaged portion 24 engage with the concave-convex engaging portions 32, 34 corresponding to the engaged portions. This prevents slippage between the engaged portions and the concave-convex engaging portions 32, 34 when engaging with the concave-convex engaging portions 32, 34, which could cause the locked state of the frame end portion 22 to be lost. Therefore, the sunshade 10 can be held in the position where the frame end portion 22 is in the locked state.

[0060] As described above, according to the first embodiment, it is possible to provide the sunshade device 101 that can stop and hold the sunshade 10 at a desired position.

[0061] According to the sunshade device 101 configured as described above, the frame end 22 of the frame member 20 can be arranged in the accommodation space 35 between the first wall portion 31 and the second wall portion 33 of the guide member 30, sandwiched from both sides in the third direction Z. This makes it difficult for the locked state of the frame end 22 to be released when the first engaged portion 23 engages with the uneven engaging portion 32 of the first wall portion 31 and the second engaged portion 24 engages with the uneven engaging portion 34 of the second wall portion 33.

[0062] According to the sunshade device 101 configured as described above, by providing the engagement portions 32, 34, each of which has concave and convex portions alternately repeated in the first direction X, on the first wall portion 31 and the second wall portion 33 of the guide member 30, the frame end portion 22 of the frame member 20 can be locked at any position in the first direction X. This makes it possible to reliably stop and hold the sunshade 10 at any position.

[0063] In the sunshade device 101 configured as described above, the first engaged portion 23 has its locking claw 23a fitted into the gap 32b of the engaging portion 32 of the first wall portion 31, and the second engaged portion 24 has its flat surface 24a abutting against the inclined surface 34c of the engaging portion 34 of the second wall portion 33, thereby locking the frame end portion 22. Providing the locking claw 23a on the first engaged portion 23 ensures that the first engaged portion 23 first engages with the gap 32b of the engaging portion 32 of the first wall portion 31. Then, by abutting the flat surface 24a of the second engaged portion 24 against the inclined surface 34c of the engaging portion 34 of the second wall portion 33, the first engaged portion 23 can be maintained in an engaged state to prevent disengagement of the first engaged portion 23. At this time, the second engaged portion 24 performs an auxiliary engagement function for the first engaged portion 23. Since it is only necessary to provide the flat surface 24a on the second engaged portion 24, it is possible to simplify both the structure of the second engaged portion 24 and the structure of the engaging portion 34 of the second wall portion 33 associated therewith.

[0064] The present invention is not limited to the above-described embodiment and its modifications, and various applications and modifications are possible without departing from the object of the present invention. For example, the following embodiments can be implemented by applying the above-described embodiment and its modifications.

[0065] In the above embodiment, an example has been given in which two engaged portions (first engaged portion 23 and second engaged portion 24) are provided on frame end portion 22, but the number of engaged portions is not limited to this, and another engaged portion may be added as necessary. In this case, as an engaged portion is added, an engaging portion provided on guide member 30 is also added.

[0066] In the above embodiment, the case where the movement restricting portion 26 is provided at the frame end portion 22 has been exemplified, but the movement restricting portion 26 may be omitted as necessary.

[0067] In the above embodiment, the sunshade device 101 is provided on the vehicle door 2, but the location where the sunshade device 101 is provided is not limited to the vehicle door 2. The sunshade device 101 may be provided on the back door or the window portion of the sunroof of the vehicle 1, for example. [Explanation of symbols]
