Description

The present invention is, for example, a take-up device that is disposed in a vehicle interior such as an automobile and that winds up a sheet body such as a sunshade that shields sunlight entering the room from the outside and a tonneau cover that covers an indoor storage portion so as to be drawable. The present invention relates to a housing of a winding device for detachably mounting the bracket between mounting portions provided on a vehicle.

  2. Description of the Related Art Conventionally, for example, a sunshade that is disposed in a room of a vehicle such as an automobile and shields sunlight that enters the room from the outside, and a sheet body such as a tonneau cover that covers an indoor storage part is rewound to be retractable. A take-off device is known. In this type of winding device, both side ends are respectively held by a pair of holders at both ends of the winding device, and these holding tools of the winding device are respectively attached to mounting portions on both sides provided in the room. It is attached to the vehicle by fixing. In consideration of convenience for use in the vehicle, it is particularly preferable that the winding device for the light shielding sheet is detachable from the vehicle as required.

  As described above, with regard to the mounting structure for detachably mounting the winding device, for example, in German Patent No. 197339625, the winding device can be mounted by the axial biasing force, and this biasing force is A structure provided with an operation unit to be released is disclosed.

German Patent Invention No. 197339625 JP-A-10-329610 JP 2000-52870 A

  In the mounting structure described in German Patent No. 19739625 and Japanese Patent Laid-Open No. 10-329610, when the winding device is disengaged from the vehicle side, the winding device is moved to the vehicle side. It falls from the attachment part of this, or it has the structure which remains in the attachment part to a vehicle. Therefore, in the former case, the user needs to release the engagement while supporting the winding device. In the latter case, after releasing the engagement, the user lifts and removes the winding device from the mounting portion. There is a need.

  In addition, in the mounting structure described in Japanese Patent Laid-Open No. 2000-52870, a configuration is disclosed in which the lock lever is lifted by an elastic body when the engagement is released, but the elastic body is re-engaged with the striker. It is provided for the purpose of avoiding misalignment, and is only of a level that raises the lock lever slightly. Therefore, after releasing the engagement, the user needs to lift the winding device from the attachment portion and remove it.

An object of the present invention is to further improve the conventional technology as described above, that is, to provide a housing for a winding device that is superior in detachability.

The winding device mounting structure related to the present invention includes a winding device for winding a sheet body around a winding shaft, fixing both ends of the winding device to mounting portions of a vehicle, and spanning between the mounting portions. A winder mounting structure that is detachably mounted, and the winder includes a box-shaped housing that is pivotally supported by the winder shaft and that opens toward the winder shaft. Both mounting portions of the mounting portion are constituted by a concave portion that is open to the upper side and the side around which the winding device is bridged, and has a size that each housing fits substantially tightly. A biasing projection that is biased upward by a spring is attached, and a notch is formed in each of the two walls facing each other of both attachment parts, and a winding device is attached to the housing. Both walls of the mounting part where notches are formed An opening is formed in each facing wall, and two engaging elements retractable into the housing are attached, which are biased to the outside of the housing through each of the openings, The both housings are inserted into the mounting portion against the biasing force of the biasing protrusion while the both engaging elements are retracted into the housing, so that the engaging elements protrude through the notches of the mounting portion. The take-up device can be detached by engaging the notches with each other by retracting the engaging elements of the two housings into the housing and removing them from the notches in the mounting portion. And the housing jumps up by a predetermined amount by the biasing force of the biasing protrusion by the spring.

  According to this configuration, since the housings at both ends of the winding device greatly jump from the mounting portion of the vehicle at the time of removal, the user can remove the winding device from the mounting portion of the vehicle. Can be used. At this time, in the winding device mounting structure of the present invention, the housing can be held relatively firmly by engaging the engaging element protruding from the opposing wall of the housing with the notch of the mounting portion. Even when a relatively large biasing force is applied by the biasing protrusion, the housing can be stably held. Therefore, the urging force by the urging protrusion can be made larger than that described in the above-mentioned Japanese Patent Application Laid-Open No. 2000-52870, and the housing can be jumped more greatly, thereby improving the operability of removal. Can be increased.

Moreover, in the winding device attachment structure related to the present invention, the winding device is in a state where an urging force is applied by the urging protrusion while being attached to the attachment portion of the vehicle. For this reason, even if a running vibration of the vehicle is applied, it is possible to suppress the rattling of the winding device in the mounting portion, and the winding device can be stabilized even if there is a dimensional error of the mounting portion. Can be attached.

In the winding device mounting structure related to the present invention, it is preferable that the operation direction of each engagement element is a direction orthogonal to the urging direction of the urging protrusion. Thereby, the urging force of the urging protrusion is not applied in the operating direction of the engaging element, and the force required to operate the engaging element can be made relatively small.

  Moreover, it is preferable that the lower surface of the edge part which protrudes the outer side of a housing of each engagement element is a slope which inclines diagonally upward toward the outer side of a housing. According to this configuration, when the housing is inserted into the attachment portion, the lower surface of each engagement element comes into contact with the inner surface of the attachment portion, so that a force is applied to each engagement element in the direction in which the engagement element is retracted. For this reason, when attaching the winding device to the attachment portion of the vehicle, each engagement element can be retracted into the housing simply by inserting the housing into the attachment portion, and the attachment operation is facilitated.

The housing of the winding device of the present invention is a housing at both ends of the winding device that winds the sheet body around the winding shaft, and the winding shaft can be rotated when viewed in a plane perpendicular to the winding shaft. The winding shaft mounting portion to which the shaft supporting means for supporting the shaft is mounted is provided in the center, and has a peripheral wall surrounding the winding shaft mounting portion, and has a shape opened to the winding shaft as a whole. Is mounted with two engaging elements retractable into the housing, each of which is formed with a pair of openings at opposite positions and biased to the outside of the housing through each of the openings; A guide portion that slidably guides both engaging elements in a direction to advance and retreat from the respective openings of the housing, and an urging means for urging both engaging elements in a direction protruding to the outside of the housing; Interlocked with both engaging elements via a pair of link mechanisms An operation button which can be retracted into the housing against the biasing force of the biasing means both engagement element by an operation to move the, is provided with, serial set of linkage, end the operation A first link mechanism element fixed to the button and having the other end engaged with one of the engagement elements; one end connected to the operation button; the other end engaged with the other of the engagement elements; And a second link mechanism element that moves the engaging element in a direction opposite to the moving direction .

  In this configuration, it is advantageous that the operation direction of the operation button is a direction orthogonal to the urging direction of the urging protrusion. Accordingly, it is possible to prevent the user from being prevented from jumping up by the force applied to the operation button during removal. In this case, the outer surface of the housing protrudes outward at a position near the upper end of the front wall as viewed in the direction of the force applied to the operation button when the engaging element is retracted into the housing. It is preferable to provide a supporting protrusion. By providing such a support protrusion, when the operation button is operated, the housing can be prevented from being tilted in the mounting portion, and the jumping operation can be performed satisfactorily.

With the above-described configuration of a set of linkage mechanisms , two engaging elements projecting in opposite directions from opposite walls of the housing can be simultaneously retracted into the housing by operating a single operating button.

More specifically, one end of the second link mechanism element is rotatably connected to the operation button, and a portion near the center of the second link mechanism element is positioned in the movement direction of the operation button by a fulcrum wall formed on the housing. is regulated under the moving direction of the other end, it can be configured adapted to be reversed in the opposite direction to the moving direction of the one end. According to this configuration, when the operation button is operated, the second link mechanism rotates with the portion near the center of which the position is regulated by the fulcrum wall as a fulcrum. Therefore, the side of the second link mechanism engaged with the engaging element is operated as the end side of the second link mechanism connected to the operation button moves in the moving direction of the operation button by operating the operation button. Is moved in the direction opposite to the movement direction of the operation button, and as a result, the engaging element can be moved in the direction opposite to the movement direction of the operation button.

  As described above, according to the present invention, when the take-up device is removed, the engagement between the take-up device and the mounting portion on the vehicle body side can be released by a single operation of operating the operation button. . Then, when the engagement between the winding device and the mounting portion is released, the winding device can be jumped from the mounting portion by a desired relatively high height, that is, can be popped up dynamically, thereby removing the winding device. Operability can be improved.

Further, according to this onset bright, retractor is biased by the biasing projections, by its biasing force, in a state in which the engaging element attached to a winding device is pressed against the notch of the mounting portion of the vehicle Since it is attached, the winding device can be stably attached even if a slight dimensional error or expansion / contraction due to a temperature change occurs on the attachment portion side.

  In addition, by making the direction of operating the operation button perpendicular to the urging direction by the urging protrusion, it is possible to prevent the operation force of the operation button from interfering with the pop-up operation by the urging protrusion. Therefore, it is possible to perform the removal operation without difficulty.

  Further, according to the present invention, the operation button can be operated with a relatively small force, and the force required for removing the operation button from the mounting portion of the vehicle is reduced by popping up the winding device. Therefore, an excessive operating force is not required for removing the winding device.

  Hereinafter, a tonneau cover winding device mounting structure will be described as an example of a preferred embodiment of the present invention with reference to the drawings.

  FIG. 1 is an external view showing a rear portion of a hatchback type automobile to which a tonneau cover device is attached, and FIG. 2 is an external view showing a state in which the tonneau cover device is removed. This type of automobile is provided with a luggage placement space called a tonneau part behind a rear seat, and a tonneau cover device can be used to cover the tonneau part so as not to be seen from the outside.

  The tonneau cover device includes a tonneau cover 1 that is a flexible sheet body and a winding device 2 that can wind and hold the tonneau cover 1. The winding device 2 includes a winding shaft 2b that winds and holds the tonneau cover 1, a housing 10 that is provided at both ends of the winding shaft 2b and rotatably supports the winding shaft 2b (only one side is shown), a winding A casing 2a extending between both housings 10 is provided so as to cover the take-up shaft 2b. Further, the tonneau cover device has an unillustrated urging means for urging and energizing the take-up shaft 2b, and the tonneau cover 1 is urged by the urging means in the direction of being always taken up.

  The casing 2a has a size that can accommodate the winding shaft 2b in a state in which the tonneau cover 1 is wound, and has a slit 2c that extends in parallel to the winding shaft 2b. At the tip of the tonneau cover 1, a thick and rigid gripping edge 1 a is provided so as to be easily gripped when the tonneau cover 1 is pulled out. The slit 2c of the casing 2a has a size that allows the tonneau cover 1 to be taken in and out. On the other hand, the thick gripping edge 1a cannot pass through the slit 2c, that is, has a thickness larger than the height of the slit 2a.

  The winding device 2 fixes the housings 10 on both sides to the mounting portions 3b formed on the garnish trims 3 on both sides of the vehicle as recesses into which the housing 10 can be fitted from above, and on the upper portion near the front end of the tonneau portion. It is installed across the vehicle on both sides. In addition, the garnish trim 3 is provided with guide rails 3 a that can slide the left and right ends of the gripping edge 1 a of the tonneau cover 1. The guide rail 3a extends substantially horizontally from the mounting portion 3a toward the rear of the vehicle. Locking means that can engage the left and right ends of the gripping edge 1a, for example, a locking groove (not shown), is provided in a portion of the guide rail 3a near the rear end of the vehicle.

  Next, a method for using the tonneau cover device will be described. Even when the tonneau cover 1 is wound around the winding device 2, only the thick gripping edge 1a remains outside the casing 2a. The user grasps the gripping edge 1a. The tonneau cover 1 can be pulled out rearward of the automobile along the guide rail 3a. Then, the user engages the right and left ends of the gripping edge 1a with the above-described locking means, so that the tonneau cover 1 is against the urging force of the winding device 2 as shown in FIG. It can be held in a state of covering the top.

  When the gripping edge 1a is removed from the locking means, the tonneau cover 1 is wound up by the winding device 2, and the gripping edge 1a moves forward with this, and finally the thick gripping edge 1a. Only the state is left outside the winding device 2. In this way, the upper part of the tonneau part can be opened.

  The tonneau cover device of the present embodiment is configured to be easily detachable from the vehicle. It is preferable that the tonneau cover device be detachable because the degree of freedom of the usage mode of the vehicle can be increased.

  As shown in FIG. 2, engaging elements 30 and 35 (see also FIG. 4) that can protrude forward and backward are attached to the housings 10 at both ends as a configuration that allows the tonneau cover device to be detachable. As will be described later in detail, the engaging elements 30 and 35 are biased in a direction protruding outward, and are retracted into the housing 10 by operating the operation buttons 20 provided on the upper surface of the housing 10. be able to. The lower surfaces of the tips of the engaging elements 30 and 35 projecting out of the housing 10 are slopes inclined obliquely upward toward the outside.

  On the other hand, the attachment portion 3b of the garnish trim 3 is formed with narrow notches 3d and 3e (see also FIG. 5) on the front and rear walls of the attachment portion 3b. Moreover, the opening 3c is formed in the bottom wall of the attaching part 3b, and the biasing protrusion 40 protrudes in the attaching part 3b through this opening. As shown in FIG. 3, the biasing protrusion 40 is supported by a support member 45 attached to the back side of the garnish trim 3 by screws 46 a and 46 b, and is biased upward by a spring 41.

  Next, a method for attaching / detaching the tonneau cover device to / from the vehicle will be described.

  First, when attaching the tonneau cover device, the left and right housings 10 are inserted into the left and right attachment portions 3b from above. At this time, the front and rear walls of the mounting portion abut against the slopes of the front ends of the engagement elements 30 and 35, so that a force is applied to the engagement elements 30 and 35 in the direction in which the engagement elements 30 and 35 are retracted into the housing 10. 35 is simply retracted by simply inserting the housing 10. As the housing 10 is further inserted, the engagement elements 30 and 35 move downward while sliding with their tips contacting the front and rear walls of the mounting portion 3b. Even after the lower surface of the housing 10 abuts against the urging protrusion 40, the housing 10 is pushed down against the urging force of the urging protrusion 40, and the engaging elements 30 and 35 are located at the notches 3d and 3e. When reaching, the engaging elements 30 and 35 project to the outside of the housing 10 through the notches 3d and 3e by the biasing force applied thereto, and engage with the notches 3d and 3e.

In this way, the tonneau cover device can be attached to the vehicle. In this state, the housing 10 is applied with an urging force upward by the urging force of the urging protrusion 40, but the engaging elements 30, 35 engage with the notches 3 d, 3 e, thereby attaching the mounting portion 3 b. It is restrained from popping out and is fixed. According to this winding device mounting structure, the winding device 2 is urged by the urging protrusion 40 in this manner, and the engaging elements 30 and 35 are pressed against the notches 3d and 3e of the mounting portion 3b of the vehicle. Since it is attached, the winding device 2 can be stably attached even if there is a delicate dimensional error on the attachment portion 3b side or expansion and contraction due to temperature change. Further, even if the vehicle is subjected to running vibration, it is possible to suppress the rattling of the winding device 2 in the mounting portion 3b. Next, when removing the tonneau cover device from the vehicle, The operation button 20 is operated. As a result, the engagement elements 30 and 35 are retracted into the housing 10 and disengaged. Then, the housings 10 on both sides are pushed upward by the biasing protrusions 40. At this time, the urging force of the urging projection 40 is set so strong that the housing 10 jumps out (pops up) with a considerable amount of force upward from the mounting portion 3b. The height of the pop-up is suitably 5 mm or more, and particularly preferably 10 mm or more. By popping up in this manner, the user can easily remove the tonneau cover device from the attachment portion 3b.

  When the operation button 20 is operated in this way, the engagement elements 30 and 35 operate in a direction orthogonal to the direction of the urging force of the urging protrusion 40, so that the urging force of the urging protrusion 40 is the engagement element. There is no direct addition in the direction of movement of 30,35. Therefore, the resistance when operating the operation button 20 is only the frictional force between the engaging elements 30 and 35 and the notches 3d and 3e and the urging force to the engaging elements 30 and 35. The frictional force between the engaging elements 30 and 35 and the notches 3d and 3e is selected by appropriately selecting these members, and by appropriately processing the contact portion, the biasing force of the biasing protrusion 40 is compared. Even a strong one can be made relatively small. Further, it is not necessary to increase the urging force to the engagement elements 30 and 35 so much. Therefore, the force required to operate the operation button 20 can be made relatively small.

  Next, the configuration of the housing 10 to which the engagement elements 30 and 35 and the operation button 20 are attached will be described in more detail with reference to FIGS. 4 is an exploded perspective view of the housing 10 portion, FIG. 5 is a side view of the housing 10 fixed to the mounting portion 3b as seen from the winding shaft 2b side, and FIG. 6 is a side view of the housing 10 on the winding shaft 2b side. It is sectional drawing seen from. In these figures, the housing 10 attached to the right side of the vehicle is shown, but the one attached to the left side has a symmetrical configuration with respect to this and a central plane extending in the vertical direction in the front-rear direction of the vehicle. Yes.

  The housing 10 has a rectangular box shape opened to the take-up shaft 2b side, and the size of the front and rear of the housing 10 is such that the fitting portion 3b fits almost exactly as shown in FIG. Yes. On the outer side of the front wall of the housing 10, a support protrusion 16 that protrudes outward is formed near the upper end thereof. The left and right housings 10 hold the casing 2a (see FIG. 2) so as to be in contact with the inside of the upper and lower and front and rear walls of the housing 10 so as to be sandwiched between the left and right housings 10.

  In the vicinity of the center of the housing 10, there is provided a take-up shaft attachment portion 17 to which a shaft support means for supporting the take-up shaft 2b, a rotation urging means and the like (not shown) are attached. The shaft support means is formed as a shaft holder that can rotate relative to the housing 10, and the winding shaft 2 b has shaft holders provided at both ends thereof mounted on the winding shafts of the left and right housings 10. It is attached to and supported by the portion 17. The shaft support means is preferably combined with a damper device that generates a predetermined resistance force against the rotation of the winding shaft 2b by the urging force of the rotation urging means and smoothes the rotation operation.

  Openings 14a and 14b are formed in the front and rear walls of the housing 10 at positions facing each other, and a hollow portion extending between the openings 14a and 14b is provided between the portions provided with the openings 14a and 14b. A rectangular cylindrical guide portion 11 is provided. The openings 14a and 14b and the hollow portion in the guide portion 11 are sized so that the engaging elements 30 and 35 can be slidably fitted therein. The engaging elements 30 and 35 are provided on the side to be inserted into the housing 10, a protrusion that can be fitted in the center of the spring 33, which is a helical spring in the example shown in the figure, and a groove formed around the root thereof And is inserted into the guide portion 11 with a spring 33 interposed therebetween. Therefore, the engaging elements 30 and 35 are guided so as to slide in the guide portion 11, project out of the housing 10 through the openings 14 a and 14 b, and retract into the housing 10. 10 is urged in a direction protruding outward.

  A guide surface 12 is formed on the upper surface of the housing 10 so that the operation button 20 is slidable in the front-rear direction. The guide surface 12 is slightly lower than the surroundings. A moving opening 13 is formed. On the lower surface of the operation button 20, a projecting portion 23 extending in the front-rear direction is formed integrally with the operation button 20 at the center in the left-right direction, and the projecting portion 23 slides in the sliding opening 13. Guided as possible. The operation button 20 is formed with a recess suitable for placing a finger on the rear end thereof so as to facilitate the sliding operation.

  A hanging leg (first link mechanism element) 21 extending vertically downward is formed at the rear end of the protrusion 23. The lower end of the hanging leg 21 extends into the guide portion 11 through a notch 11b provided on the upper wall of the guide portion 11, and enters an engagement hole 32 opened on the upper surface of the rear engagement element 30. Has been inserted.

  Similarly, the front engagement element 35 is formed with an engagement hole 37 opened on the upper surface thereof, and a link leg (second link mechanism element) 25 is inserted into the engagement hole 37. . A shaft support portion 26 is provided at the end of the link leg 25 opposite to the end inserted into the engagement hole 37. The link leg 25 is rotatably connected to the operation button 20 by connecting the shaft support 26 and a shaft support 22 provided at the front end of the protrusion 23 of the operation button 20. Inside the side wall of the housing 10, fulcrum walls 15a and 15b for regulating the position in the front-rear direction of the link leg 25 are formed so as to protrude from the inner surface of the side wall so as to sandwich the portion near the center of the link leg 25. ing.

  Next, the operation of the housing 10 will be described.

  FIG. 6A shows the housing 10 in a state where no external force is applied to the operation button 20 and the engagement elements 30 and 35. In this state, the operation button 20 is located at the rear end of the sliding range by the urging force of the spring 33 applied via the engagement elements 32 and 35, the hanging leg 21 and the link leg 25. 30 and 35 protrude outside the housing 10.

  Next, FIG.6 (b) has shown the state which moved the operation button 20 to the front end of the sliding range. When the operation button 20 is slid forward, the hanging leg 21 formed integrally with the operation button 20 moves forward, and the rear engagement element 30 moves forward. On the other hand, the link leg 25 rotates around the connecting portion with the projecting portion 23 with this portion serving as a fulcrum by stopping the forward movement with the center abutting against the fulcrum wall 15a. As the portion moves forward, the opposite end of the engagement element 35 inserted into the engagement hole 37 moves backward. Thereby, the front engagement element 35 is moved backward. When the operation button 20 is moved to the front end of the slide movement range, the engagement elements 30 and 35 are completely retracted into the housing 10. As described above, according to this configuration, both the engagement elements 30 and 35 can be retracted into the housing 10 and the engagement of the housing 10 can be released by a single operation of sliding the operation button 20.

  When the operation button 20 is slid forward, the housing 10 has a force A (35 to 50 N) applied upward by the biasing projection 40 and a user operation as shown in FIG. A resultant force A + B with a lateral force B (about 20N) applied to the button 20 is applied, and therefore, a force in a diagonally upward direction is applied. At this time, the support protrusion 16 abuts against the front wall of the mounting portion 3b, whereby the entire housing 10 is prevented from being inclined obliquely. In this way, the housing 10 can be kept in a substantially straight state, whereby the housing 10 can be favorably popped up when the engagement of the housing 10 is released. The force A is set to a certain level or more so that the popped-up housing 20 does not fall again into the mounting portion 3b due to its own weight, and when the engaging elements 30, 35 are retracted, 35 and notches 3d and 3e are preferably set not to be excessively large so that the friction does not become excessive. In consideration of these, it is set to 35 to 50 N in this embodiment.

  The support protrusion 16 is provided at an optimal position for suppressing the inclination of the housing 10 due to the resultant force A + B as described above, and its height is suitably set to several mm to several tens of mm. When popping up, it is preferable to round the tip of the support protrusion 16 so as not to cause a large frictional resistance.

  As described above, according to the present embodiment, the tonneau cover device can be disengaged by operating the operation buttons 20 provided on the housings 10 at both ends thereof. At this time, the tonneau cover device can be greatly jumped by the urging force of the urging protrusion 40, thereby assisting in the operation of removing the tonneau cover device from the mounting portion 3b of the vehicle, so that a large force is not required for the operation. The operation for removing the tonneau cover device can be facilitated.

  In the present embodiment, the constituent members such as the operation button 20, the link leg 25, the engagement elements 30 and 35 movably attached to the housing 10 are preferably formed by resin molding. It is preferable to provide a cushioning material such as rubber on the surface where there is a possibility of occurrence of rattling or backlash, thereby suppressing the generation of abnormal noise and the like, and enabling the operation to be performed satisfactorily.

  In the present embodiment, an example of a mechanism for releasing the engagement by operating the operation button 20 has been described. However, the present invention is not limited to the configuration of this mechanism, and the mechanism is engaged via a set of link mechanisms. Various modified mechanisms for operating the combined elements 30 and 35 may be used. For example, in the present embodiment, the biasing means for biasing the engagement elements 30 and 35 has been described using a helical spring, but a leaf spring or the like may be used.

  In any case, it is preferable that the operation direction of the operation button 20 is a direction orthogonal to the urging direction by the urging protrusion 40. By doing so, the pop-up of the housing 10 can be prevented from being hindered by the force for operating the operation button 20, and the housing 10 can be removed smoothly.
