Description

The present disclosure relates to a vehicle-mounted roof box variable capacity mechanism.

A roof box that is fixed on the roof of a vehicle is used. More specifically, a roof carrier is fixed to the roof of a vehicle, and a roof box is fixed to a crossbar of the roof carrier. Considering the case where the roof of the parking lot is low or when using a mechanical parking lot, the height of the roof box should be lower. On the other hand, there are times when you want to store more luggage in the roof box.

In response to such user demands, variable capacity roof boxes are also available on the market. Patent Document 1 below discloses a variable capacity roof box. This roof box is composed of a bottom case and a cover that closes an upper opening of the bottom case. A roof box mounted on a vehicle is provided with a plurality of hinges on the right side of the vehicle, and a catch mechanism is provided on the left side of the vehicle for maintaining the cover in a closed state. Thereby, by lifting the vehicle left side of the cover while releasing the catch mechanism, the cover can be opened centering on the vehicle right hinge.

The catch mechanism includes a pair of latches on the bottom case side and a pair of strikers on the cover side that are engaged with the latches when the cover is closed. The catch mechanism also includes a locking mechanism that locks the latch and striker in a locked state. Here, the positions of the plurality of hinges can be adjusted up and down, respectively, by the link mechanisms, and the position of the striker with respect to the cover can also be adjusted up and down, respectively. In this way, by adjusting the hinge and the striker, the position of the closed cover can be moved upward relative to the bottom case, and as a result, the capacity of the roof box can be increased.

FIG. 3 is a perspective view showing the inside of the roof box (in a small capacity state). FIG. 3 is an enlarged perspective view of a latch of the variable capacity mechanism (catch mechanism). FIG. 3 is an enlarged perspective view of the striker of the catch mechanism (in a small capacity state). It is an enlarged perspective view of the above-mentioned striker (large capacity state). FIG. 3 is an enlarged perspective view of the catch mechanism (in a large capacity state). It is an external perspective view of the said roof box (large capacity state).

Hereinafter, an in-vehicle roof box capacity variable mechanism according to an embodiment will be described with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of the roof box 1 in a closed state. The left side in FIG. 1 is the front of the vehicle. A roof carrier (not shown) is fixed to the vehicle, and the roof box 1 is fixed to two crossbars of the roof carrier by its clamp mechanism 2. The crossbars extend in the lateral direction of the vehicle, and one crossbar is located at the front of the roof and the other is located at the rear of the roof.

The roof box 1 includes a bottom case 1a and a cover 1b that closes an upper opening of the bottom case 1a. In the roof box 1 of this embodiment, the cover 1b can be opened upward from either the right side or the left side of the vehicle. The roof box 1 of this embodiment is equipped with a capacity variable mechanism which will be explained in detail later, and its internal capacity can be set in two levels. FIG. 1 shows a state where the capacity is small (hereinafter referred to as a small capacity state). Note that the roof box 1 in a high capacity state is shown in FIG. 7 (hereinafter referred to as a high capacity state).

In the small capacity state, the height of the roof box 1, that is, the vehicle height can be lowered. On the other hand, in a large-capacity state, the height of the roof box 1, that is, the height of the vehicle increases, but a large amount of luggage can be stored inside the roof box 1. The height of the roof box 1 is adjusted by adjusting the vertical position of the cover 1b with respect to the bottom case 1a. Adjustment of the vertical position of the cover 1b with respect to the bottom case 1a, that is, the operation of the variable capacity mechanism will be described in detail later.

As shown in FIG. 2, catch mechanisms 3, which are the main parts of the variable capacity mechanism of this embodiment, are attached to the inner surfaces of the left and right side panels of the bottom case 1a and the cover 1b, respectively. Each catch mechanism 3 is provided between the bottom case 1a and the cover 1b, and includes a latch 30 attached to the bottom case 1a and a striker 31 attached to the cover 1b. Each catch mechanism 3 is provided inside the roof box 1 when the cover 1b is in the closed state, and cannot be accessed when the roof box 1 is in the closed state, ensuring safety against theft of luggage. There is.

Note that the cover 1b is not shown in FIG. 2, and only the striker 31 fixed to the cover 1b is shown. Moreover, in FIG. 2, only the rail 20 of the clamp mechanism 2 mentioned above is shown, and the clamp unit slidably attached to the rail 20 is not shown. As shown in FIG. 2, beads are formed in a grid shape on the bottom plate of the bottom case 1a to improve surface rigidity. Note that, as shown in FIG. 1, the bottom case 1a and the cover 1b are formed such that the circumferential wall of the cover 1b is located outside the circumferential wall of the bottom case 1a when the roof box 1 is in the closed state. There is. Therefore, rain and the like are prevented from entering the inside of the roof box 1, and the upward opening operation of the cover 1b can be performed smoothly.

The catch mechanism 3 is a mechanism for maintaining the cover 1b in a closed state so that the cover 1b does not open accidentally. When the cover 1b is closed, the striker 31 is locked to the latch 30. In this embodiment, two are provided spaced apart along one side of the roof box 1 (for example, the right side of the vehicle), and these two are connected by a connecting rod 32. The two catch mechanisms 3 can be interlocked by the connecting rod 32. A locking mechanism 33 for locking the cover 1b in the closed state and a push button 34 for releasing the locked state between the latch 30 and the striker 31 are also provided between the pair of catch mechanisms 3 connected by the connecting rod 32. It is being Push button 34 is incorporated into locking mechanism 33. The push button 34 is provided with a keyhole into which a key 35 for operating the lock mechanism 33 is inserted.

In addition, in this embodiment, as shown in FIG. 2, links 36 that maintain the open state of the cover 1b are attached to the front and rear parts of the roof box 1 between the bottom case 1a and the cover 1b. There is. A damper may be incorporated into the link 36.

In this embodiment, the two catch mechanisms 3 connected by the above-mentioned connecting rod 32 are also provided symmetrically on the opposite side (for example, the left side of the vehicle) opposite to the above-mentioned one side. In this embodiment, the pair of catch mechanisms 3 on each side also function as hinges for opening and closing the cover 1b. Thereby, as described above, in this embodiment, the cover 1b can be opened from either the right side or the left side of the vehicle. When opening the cover 1b from the right side of the vehicle, the pair of catch mechanisms 3 on the left side of the vehicle function as hinges. On the other hand, when the cover 1b is opened from the left side of the vehicle, the pair of catch mechanisms 3 on the right side of the vehicle function as hinges. The hinge function of the catch mechanism 3 will also be explained in detail later.

The catch mechanism 3 will be explained in detail. The four catch mechanisms 3 of this embodiment have the same configuration. However, regarding the latch 30, the extending direction of the connecting rod 32 described above differs depending on its installation position. Further, regarding the striker 31, the shape of its upper part is partially different in order to avoid interference with the cover 1b. First, the latch 30 will be explained with reference to FIG. Although the side wall of the bottom case 1a is present on the right side in FIG. 3, the bottom case 1a is not shown in FIG.

The latch 30 includes a latch bracket 30a fixed to the bottom case 1a with rivets, and a hook 30b as a locking pawl that is swingably attached to the latch bracket 30a. The latch bracket 30a has a shape that covers a portion other than the tip of the hook 30b. Each side plate portion of the latch bracket 30a is provided with a V that guides a first bar 31c1 as a first locked portion or a second bar 31c2 (see FIG. 4) as a second locked portion of the striker 31, which will be described later. A letter-shaped guide notch 30a1 is formed.

The hook 30b is swingably attached to the latch bracket 30a via the above-mentioned connecting rod 32. That is, the hook 30b is non-rotatably fixed to the connecting rod 32, and the connecting rod 32 is rotatably supported by the latch bracket 30a. The connecting rod 32 extends from the latch bracket 30a toward the other pair of catch mechanisms 3. The central axis of the connecting rod 32 coincides with the swing axis of the hook 30b, and the connecting rod 32 extends along this swing axis. The tip of the hook 30b is either protruded into the guide cutout 30a1 or retracted from the guide cutout 30a1, depending on the swinging of the hook 30b.

A torsion coil spring (not shown) is housed inside the hook 30b as a biasing member that swings its tip toward the side wall of the bottom case 1a, that is, in the locking direction. A connecting rod 32 is inserted through the coil portion of the torsion coil spring. Therefore, if the hook 30b and the bar 31b are not engaged and no force other than the biasing force of the torsion coil spring is acting, the tip of the hook 30b will be at the engagement position with the bar 31b (see Figure 3). It is located closer to the side wall of the bottom case 1a than the position shown in FIG.

The upper surface of the hook 30b is a curved convex surface. When closing the cover 1b, the first bar 31c1 or the second bar 31c2 of the striker 31 comes down from above and is guided to the guide cutout 30a1. The guided first bar 31c1 or second bar 31c2 pushes the curved convex surface of the hook 30b, and the hook 30b is swung counterclockwise in FIG. 3 against the biasing force of the torsion coil spring described above. Ru. When the first bar 31c1 or the second bar 31c2 reaches the bottom of the guide notch 30a1, the contact between the first bar 31c1 or the second bar 31c2 and the curved convex surface is eliminated. As a result, the biasing force of the torsion coil spring causes the hook 30b to swing again so that its tip protrudes into the guide notch 30a1, that is, to return to the state shown in FIG. 3. In this way, the locked state of the catch mechanism 3 is completed.

When the push button 34 described above is pressed, the connecting rod 32 is rotated around its central axis, and the locked state described above is released. Therefore, while the push button 34 is pressed, the first bar 31c1 or the second bar 31c2 can be moved upward, so the cover 1b can be opened. Note that the swinging hook 30b is covered by the latch bracket 30a. Although cargo is loaded on the bottom case 1a, since the hook 30b is covered by the latch bracket 30a, swinging of the hook 30b is prevented from being obstructed by the cargo.

Next, the striker 31 will be explained with reference to FIGS. 4 and 5. FIG. 4 shows the striker 31 when the roof box 1 is in a small capacity state, and FIG. 5 shows the striker 31 when the roof box 1 is in a large capacity state. Although the side wall of the cover 1b is present on the left side in FIGS. 4 and 5, the cover 1b is not shown in FIGS. 4 and 5.

The striker 31 includes a striker bracket 31a fixed to the cover 1b with rivets, and a swing arm 31b as a locked member attached to the striker bracket 31a. The swing arm 31b can swing relative to the striker bracket 31a and can be fixed at a predetermined position. The striker bracket 31a has a swan neck shape, and its tip is bifurcated. A swing shaft portion of the swing arm 31b is arranged inside this bifurcated portion.

A bolt 31d is passed through the bifurcated portion of the striker bracket 31a and the swing axis of the swing arm 31b. The head of the bolt 31d is fixed to one of the bifurcated parts of the striker bracket 31a or is held unrotatably. A knob 31e with a built-in nut is attached to the tip of the bolt 31d. By tightening the knob 31e, the swing arm 31b can be fixed at a predetermined swinging position. Three ribs 31f are formed inside the striker bracket 31a to ensure strength. Only the central rib 31f reaches the back surface of the attachment portion of the striker bracket 31a to the cover 1b.

The swing arm 31b includes a first arm 31b1 as a first arm extending from its swing axis in a first direction perpendicular to the swing axis, and a first arm 31b1 extending from its swing axis in a first direction perpendicular to the swing axis. It has a second arm 31b2 as a second arm portion extending in a second direction different from one direction. That is, the plane including both the first direction and the second direction is perpendicular to the swing axis. The first arm 31b1 has a first bar 31c1 at its tip as a first locked portion that can be locked by the hook 30b. Similarly, the second arm 31b2 also has a second bar 31c2 at its tip as a second locked portion that can be locked to the hook 30b.

The tip of the first arm 31b1 is split into two parts, and a first bar 31c1 is attached to connect the two parts. The tip of the second arm 31b2 is also bifurcated, and a second bar 31c2 is attached to connect the two forked portions. The space between the bifurcated portions of the first arm 31b1 and the second arm 31b2 is formed to allow the hook 30b to swing when engaged with the hook 30b and to avoid interference with the latch bracket 30a.

The length of the first arm 31b1 is shorter than the second arm 31b2, and the capacity of the roof box 1 can be changed by this difference in length. As shown in FIG. 4, the striker bracket 31a is formed such that the second arm 31b2 and the striker bracket 31a (bifurcated portion thereof) come into contact when the hook 30b and the first bar 31c1 are engaged. . Similarly, as shown in FIG. 5, the striker bracket 31a is formed such that the first arm 31b1 and the striker bracket 31a are in contact with each other when the hook 30b and the second bar 31c2 are engaged.

In the state shown in FIG. 5, the central rib 31f of the striker bracket 31a is in contact with the first bar 31c1, and the bifurcated portions of the first arm 31b1 are in contact with the ribs 31f on both sides. That is, the swing arm 31b is quickly positioned at the first predetermined position shown in FIG. 4, which realizes the small capacity state of the roof box 1, and the second predetermined position shown in FIG. 5, which realizes the large capacity state of the roof box 1. can do. The swing arm 31b can be fixed in a predetermined position simply by bringing the swing arm 31b into contact with the striker bracket 31a and tightening the knob 31e.

A hole 31g is also formed in the striker bracket 31a in order to produce a click feeling when the swing arm 31b is at a predetermined position (first or second predetermined position). Although not visible in FIGS. 4 and 5, two protrusions that engage with the hole 31g to create a click feeling are formed on the side surface of the swing arm 31b. The hole 31g and the protrusion also have the effect of temporarily holding the swing arm 31b to some extent until the knob 31e is tightened. The hole 31g and the protrusion may be provided only on one of the bifurcated portions of the striker bracket 31a, or may be provided on both.

Further, the angle θ formed by the first arm 31b1 and the second arm 31b2 is an obtuse angle (90°<θ<180°). This obtuse angle is set to an angle that satisfies the following [1] and [2]. [1] When the first bar 31c1 and the hook 30b are in a locked state (see FIG. 4), the second arm 31b2 is extended along the inner surface of the cover 1b. [2] When the second arm 31b2 and the hook 30b are in a locked state (see FIG. 5), the first arm 31b1 is extended toward the inner surface of the cover 1b.

Regarding [1] above, as can be seen from FIG. 1, the shape of the cover 1b is arched in a cross section perpendicular to the swing axis of the swing arm 31b. The above [1] means that when the roof box 1 is in a small capacity state, the second arm 31b2 that is not engaged with the hook 30b is extended along the inner surface of the arch-shaped cover 1b. Therefore, interference between the second arm 31b2 and the luggage inside the roof box 1 is minimized. In other words, the swing arm 31b does not obstruct loading of cargo as much as possible.

On the other hand, the above [2] means that when the roof box 1 is in a large capacity state, the first arm 31b1 that is not engaged with the hook 30b is extended in the direction opposite to the cargo inside the roof box 1. As shown in FIG. 5, at this time, the first arm 31b1 is located inside the striker bracket 31a. That is, in a large-capacity state where a large amount of cargo is desired to be loaded, the swing arm 31b does not obstruct loading of the cargo at all. In this way, in order to satisfy both [1] and [2] above, it is necessary that at least the above-mentioned angle θ is an obtuse angle.

The catch mechanism 3 that realizes the variable capacity mechanism of this embodiment is constructed by the latch 30 and striker 31 described above, but as described above, the catch mechanism 3 is spaced apart along one side of the roof box 1. There are two. The two hooks 30b of the two catch mechanisms 3 are connected by a connecting rod 32 extending along their swing axes. Therefore, when opening and closing the cover 1b from one side, the open side can be caught reliably, and the cover 1b can be easily opened by interlocking the two catch mechanisms 3 by the connecting rod 32.

When opening and closing the cover 1b from one side in this way, the two catch mechanisms 3 on the side opposite to this one side are in a locked state (including a locked state), and the two sets of hooks 30b and The first bar 31c1 (or the second bar 31c2) constitutes a hinge mechanism. Conversely, when opening and closing the cover 1b from the opposite side, the two sets of hooks 30b and the first bar 31c1 (or the second bar 31c2) on one side constitute a hinge mechanism. That is, the cover 1b can be opened both ways.

Further, in addition to the catch mechanism 3, it is also necessary to release the above-mentioned link 36 that maintains the open state of the cover 1b, but in this embodiment, by simultaneously releasing the locked state of the four catch mechanisms 3, the cover 1b It is also possible to completely separate the bottom case 1a from the bottom case 1a. If the cover 1b can be completely separated from the bottom case 1a, it will be easier to clean the roof box 1, and it will also be easier to fix the roof box 1 to and remove it from the roof carrier.

The adjustment of the catch mechanism 3 when changing the roof box 1 from a small capacity state to a large capacity state will be briefly explained. In the small capacity state of the roof box 1 shown in FIG. 1, the striker 31 of the catch mechanism 3 is in the state shown in FIG. The state in which the striker 31 is engaged with the latch 30 is shown in FIG. From this state, the cover 1b is opened by pressing the push button 34 on one side (for example, the above-mentioned side) of the roof box 1 to release the locked state between the striker 31 and the latch 30.

After loosening the knob 31e of each of the two strikers 31, the swing arm 31b is swung so that the second arm 31b2 extends downward. The predetermined position at that time is a position where the first arm 31b1 comes into contact with the striker bracket 31a. In this state, tighten the knob 31e to fix the swing arm 31b. This state is the state shown in FIG. The cover 1b is closed, and the adjustment of the catch mechanism 3 on one side is completed. Note that on one side, both the first arm 31b1 in the small capacity state in FIG. 4 and the second arm 31b2 in the high capacity state in FIG. Since it is located almost on the orbit, the cover 1b can be closed.

Next, on the other side of the roof box 1 (for example, the opposite side mentioned above), the two strikers 31 are similarly adjusted from the state shown in FIG. 4 to the state shown in FIG. In this case as well, on the opposite side, both the first arm 31b1 in the small capacity state in FIG. 4 and the second arm 31b2 in the high capacity state in FIG. Since the cover 1b is located approximately on a circular orbit, the cover 1b can be closed. When this adjustment is completed, the roof box 1 enters the high capacity state shown in FIG. 7, the distance between the bottom case 1a and the cover 1b increases, and the load capacity of the roof box 1 increases. The link 36 described above automatically accommodates this distance increase. The state in which the striker 31 is engaged with the latch 30 in the high capacity state is shown in FIG.

The variable capacity mechanism of this embodiment includes a catch mechanism 3 that is provided between the bottom case 1a of the roof box 1 and the cover 1b that closes the upper opening of the bottom case 1a, and that maintains the closed state of the cover 1b with respect to the bottom case 1a. We are prepared. The catch mechanism 3 is provided inside the roof box 1 in the closed state, and includes a latch 30 attached to the bottom case 1a and a striker 31 attached to the cover 1b. The latch 30 includes a latch bracket 30a fixed to the bottom case 1a, and a hook 30b swingably attached to the latch bracket 30a. The striker 31 includes a striker bracket 31a fixed to the cover 1b, and a locked member (swing arm) 31b that can swing relative to the striker bracket 31a and be fixed at a predetermined position. The locked member has a first arm portion (first arm) 31b1 and a second arm portion (second arm) 31b2. The first arm portion (first arm) 31b1 extends from the swing shaft in a first direction perpendicular to the swing shaft, and has a first locked end that can be locked with a hook 30b. (first bar) 31c1. The second arm portion (second arm) 31b2 extends from the swing axis in a second direction different from the first direction and perpendicular to the swing axis, and can be locked at the tip with a hook 30b. It has a second locked portion (second bar) 31c2. The length of the first arm portion (first arm) 31b1 is shorter than the length of the second arm portion (second arm) 31b2.

Therefore, according to the variable capacity mechanism of this embodiment, by swinging the locked member (swing arm) 31b, the first locked part (first bar) 31c1 is engaged with the locking claw (hook) 30b. By fixing the roof box 1 so that it stops, the capacity of the roof box 1 can be reduced and its height can be suppressed. On the other hand, if the locked member (swing arm) 31b is swung and the second locked part (second bar) 31c2 is locked with the locking claw (hook) 30b, the roof box 1 capacity can be increased. This capacity switching operation can be easily performed by simply changing the swinging position of the locked member (swing arm) 31b.

Further, according to the variable capacity mechanism of the present embodiment, when the locking claw (hook) 30b and the first locked portion (first bar) 31c1 are locked (see FIG. 4), the second arm portion (first bar) The second arm) 31b2 and the striker bracket 31a are in contact with each other. Furthermore, when the locking claw (hook) 30b and the second locked portion (second bar) 31c2 are locked (see FIG. 5), the first arm portion (first arm) 31b1 and the striker bracket 31a are in contact with each other. come into contact with Therefore, by simply bringing the first arm portion (first arm) 31b1 or the second arm portion (second arm) 31b2 into contact with the striker bracket 31a, the locked member (swing arm) 31b can be moved to a predetermined swing position. Can be positioned.

Further, according to the variable capacity mechanism of this embodiment, the angle formed by the first arm portion (first arm) 31b1 and the second arm portion (second arm) 31b2 is an obtuse angle. This obtuse angle is set to an angle that satisfies [1] and [2] below. [1] When the first locked part (first bar) 31c1 and the locking claw (hook) 30b are in a locked state (see FIG. 4), the second arm part (second arm) 31b2 is attached to the cover 1b. Extend along the inner surface of the [2] When the second locked part (second bar) 31c2 and the locking claw (hook) 30b are in the locked state (see FIG. 5), the first arm part (first arm) 31b1 is attached to the cover 1b. Extend toward the inner surface of the Therefore, in the state [1], the second arm portion (second arm) 31b2 is extended along the inner surface of the cover 1b, so that the locked member (swing arm) 31b prevents loading of cargo as much as possible. do not have. On the other hand, in the state [2], the first arm portion (first arm) 31b1 extends toward the inner surface of the cover 1b and does not extend toward the inside where the cargo is loaded. The arm) 31b does not obstruct loading of cargo at all.

Further, according to the variable capacity mechanism of the present embodiment, two catch mechanisms 3 are provided spaced apart along one side of the roof box 1, and two locking claws (hooks) of the two catch mechanisms 3 are provided. 30b are connected by a connecting rod 32 extending along their pivot axis. Therefore, the closed state of one side of the roof box 1 can be reliably held by the two catch mechanisms 3. On the other hand, since the two catch mechanisms 3 can be interlocked by the connecting rod 32, it is easy to open one side of the roof box 1.

Here, according to the variable capacity mechanism of this embodiment, the circumferential side wall of the cover 1b is located outside the circumferential side wall of the bottom case 1a in the closed state. Therefore, rain and the like are prevented from entering the inside of the roof box 1, and the upward opening operation of the cover 1b can be performed smoothly. Furthermore, two catch mechanisms 3 are also provided symmetrically on the opposite side of the above-mentioned one side. The two sets of locked catch mechanisms 3 on each side also function as a hinge mechanism for the cover. Therefore, the roof box 1 can be opened from either one side or the opposite side.

Although the embodiments have been described above, it is possible to modify or transform the embodiments based on the content disclosed above. All components of the embodiments described above and all features recited in the claims may be extracted individually and combined insofar as they do not contradict each other.
