[0015] Hereinafter, a typical embodiment of the present invention will be described with reference to Figs. 1 to 23. Configure the support structureThe support device 1 has a function of forming, as necessary, a protrusion 101 that can be used for hooking, etc., and a recess 102 that can be used for fitting, etc., on the attachment target 100. In addition, the support device 1 has a function of forming a part of the design surface 103 of the attachment target 100 when the use of the protrusion 101 and the recess 102 is not required.

[0016] Typically, such a support device 1 is provided as necessary in the cabin Ma of a vehicle M and is used to support various articles in the cabin Ma. In this case, the support device 1 is combined with a trim as an attachment target 100 constituting a wall portion of the cabin Ma, by utilizing a through hole 104 formed in the trim.

[0017] The support device 1 includes a movable body 2 that, in a reference position, constitutes a part of the design surface 103 of the attachment target 100. The support device 1 is combined with and fixed to the attachment target 100 as described above, so that the movable body 2 is provided on the attachment target 100 in such a manner that it can move between a forward position at which the movable body 2 forms a protrusion 101 that can be used for hooking or the like on the attachment target 100, and a backward position at which the movable body 2 forms a recess 102 that can be used for fitting or the like on the attachment target 100.

[0018] The support device 1 includes a case body 3 that movably supports the movable body 2 and is attached to the mounting object 100, a biasing body 4 that constantly biases the movable body 2 toward the forward position, and a control mechanism 5 for the movable body 2.

[0019] The front end 6 of the movable body 2, in the reference position of the movable body 2, substantially blocks the through hole 104, and is continuous with the design surface 103 surrounding the through hole 104 to form a part of the design surface 103. In the illustrated example, in the reference position of the movable body 2, the front end 6 of the movable body 2 is substantially flush with the design surface 103 (FIG. 1).

[0020] On the other hand, the front end 6 of the movable body 2 is positioned outward of the design surface 103 surrounding the through hole 104 when the movable body 2 is in the forward position, thereby forming a protrusion 101 on the attachment target 100 (FIG. 3).

[0021] Furthermore, when the movable body 2 is in the retracted position, the front end 6 of the movable body 2 is positioned inward of the design surface 103 surrounding the through hole 104, thereby forming a recess 102 in the attachment target 100 (FIG. 5).

[0022] The rest of the supporting device 1 except for the front end 6 side of the movable body 2 is substantially located on the non-design surface 103 side of the attachment target 100 , that is, inside 105 of the attachment target 100 .

[0023] When the support device 1 is provided in the vehicle interior Ma of the vehicle M, a shopping bag or the like can be hung directly on a wall in the vehicle interior Ma by utilizing the protrusion 101 formed by the support device 1. Also, various articles can be hung indirectly on the wall via a hanger or an S-hook.

[0024] Furthermore, as shown in FIG. 22, if a support device 1 is provided on each of the left and right wall portions within the vehicle compartment Ma, the shelf-like body can be supported within the vehicle compartment Ma by utilizing the protrusions 101 formed by the support devices 1 provided on the left and right wall portions.

[0025] In addition, by utilizing the recess 102 formed by the support device 1, parts of various articles can be combined with the wall portion by fitting or inserting them into the recess 102.

[0026] As shown in Figure 22, if a support device 1 is provided on each of the left and right walls of the vehicle compartment Ma, the rod-shaped body Ca can be supported in a bridging manner within the vehicle compartment Ma by utilizing the recesses 102 formed by the support devices 1 provided on the left and right walls.

[0027] In particular, as shown in Fig. 22, by providing a plurality of support devices 1 at intervals in the front-rear direction on each of the left and right walls of the vehicle compartment Ma, and by receiving the ends of the rod-shaped bodies Ca in recesses 102 formed by the support devices 1 at substantially the same positions in the front-rear direction of the vehicle M, it is possible to support, for example, two rod-shaped bodies Ca in a bridging manner at an interval in the front-rear direction of the vehicle M. As shown in Fig. 23, for a tonneau cover C formed by fastening one end of a curtain-shaped cover Cb to one of the two rod-shaped bodies Ca as described above and fastening the other end of the curtain-shaped cover Cb to the other of the two rod-shaped bodies Ca, by providing a plurality of support devices 1 at intervals in the front-rear direction on each of the left and right walls of the vehicle compartment Ma as described above, it is possible to support the two rod-shaped bodies Ca in a bridging manner so that the curtain-shaped cover Cb is spread over the floor of the luggage space in the vehicle compartment Ma, and it is possible to conveniently cover the floor with the curtain-shaped cover Cb.

[0028] The movable body 2 has a plate-shaped front end portion 6, a cylindrical body portion 7, and a neck portion 8 formed between the front end portion 6 and the body portion 7.

[0029] The front end 6 is plate-shaped with a plate surface oriented perpendicular to a central axis x (see FIG. 11) along the moving direction of the movable body 2. In the illustrated example, the front end 6 has left and right linear edge portions 6a along an imaginary straight line perpendicular to the central axis x, and upper and lower arc-shaped edge portions 6b following the arc of an imaginary circle with the central axis x as its center. Then, a through hole 104 of the attachment target 100 that matches the contour of the front end 6 is formed as described above. standard At this position, the through hole 104 is substantially closed, and the surface opposite the neck portion 8 is flush with the design surface 103 surrounding the through hole 104 (FIG. 1).

[0030] The neck 8 and the body 7 together form a hollow cylindrical body. The front end of this cylindrical body is closed by the front end 6, and the rear end is open. The outer diameter of the body 7 is substantially equal to the outer diameter of the imaginary circle that the arc-shaped edge 6b of the front end 6 follows. The outer diameter of the neck 8 is smaller than the outer diameter of the body 7. In the illustrated example, in the forward position, the front of the neck 8 of the movable body 2 protrudes outward beyond the design surface 103 to form the protrusion 101. The handle of a shopping bag or the like can be hung from the protrusion 101 formed in this way on the neck 8 behind the front end 6 in a manner that prevents it from falling off by the front end 6.

[0031] In the illustrated example, rectangular window holes 8a are formed in the upper and lower parts of the neck 8. These window holes 8a can be used to pass a string or the like through the protrusion 101.

[0032] Elastic pieces 9a, which become engagement parts 9 described below, are formed on the left and right sides of the body 7 at the rear end side of the body 7. The elastic pieces 9a are formed from parts of the body 7 separated by a split groove 9b that connects the front ends of upper and lower grooves formed along the central axis x with a vertical groove. A claw part 9c is formed on the outer surface side of the elastic pieces 9a.

[0033] A heart cam 20 which constitutes the control mechanism 5 described below is formed on the upper side of the body 7. The heart cam 20 is composed of a part of the body 7 which is left in an island shape by forming a circumferential guide groove 21 engraved on the outer surface of the body 7. The heart cam 20 has a pointed part 20a located at the rear and a concave part 20b located at the front (FIG. 16).

[0034] The guide groove 21 is formed in a range from the vicinity of the front end to the vicinity of the rear end of the body 7. The guide groove 21 includes a circumferential portion 21a that circulates around the heart cam 20, a first lane 21b that extends forward from the circumferential portion 21a on one side of the recessed portion 20b of the heart cam 20 (one side of a virtual straight line y that passes through the recessed portion 20b along the moving direction of the movable body 2 that passes through the recessed portion 20b / upper side in FIG. 16), a second lane 21c that extends forward from the circumferential portion 21a on the other side of the recessed portion 20b of the heart cam 20 (the other side of the straight line y / lower side in FIG. 16), and a third lane 21d that extends backward from the circumferential portion 21a along the straight line y behind the pointed portion 20a of the heart cam 20.

[0035] The groove wall located in front of the recessed portion 20b of the heart cam 20 in the circumferential portion 21a serves as a first guide wall 21e that guides the pin 22 into the second lane 21c when the movable body 2 is pushed in a first way (described later) from a state in which the pin 22 is engaged with the recessed portion 20b of the heart cam 20 by the biasing force of the biasing body 4 described later (position a in Figure 16). The portion facing upward in Figure 16 between the pointed portion 20a and the recessed portion 20b of the heart cam 20 forms a second guide wall 21f that guides the pin 22 to the upper side of the heart cam 20 in Figure 16 (one side across the straight line y) when the movable body 2 is pushed in a second way as described below from a state in which the pin 22 is at the rear end of the third lane 21d (position c in Figure 16). The groove wall of the circular portion 21a that is located above the first guide wall 21e in Figure 16 (on one side of the straight line y) is a third guide wall 21g that guides the pin 22, which is guided to the upper side of the heart cam 20 in Figure 16 by the second pushing, to the first lane 21b. The portion located above the recessed portion 20b of the heart cam 20 in Figure 16 (on one side of the straight line y) and facing the entrance of the first lane 21b is a fourth guide wall 21h that guides the pin 22 into the recessed portion 20b of the heart cam 20 when the movable body 2 moves toward the reference position due to the force of the biasing body 4 after the second push-in is completed. In the illustrated example, the distance L2 between the rear end of the third lane 21d and the recessed portion 20b of the heart cam 20 is slightly larger than the distance L1 between the front ends of the first lane 21b and the second lane 21c and the recessed portion 20b of the heart cam 20 (FIG. 16). As a result, in this embodiment, the distance that the movable body 2 moves from the reference position to the forward position is slightly larger than the distance that the movable body 2 moves from the reference position to the backward position. In the illustrated example, a circumferential stepped surface 7a facing rearward is formed inside the front end side of the body 7 (FIG. 11). In the illustrated example, the front end of a compression coil spring 19 (described later) constituting the biasing body 4 is adapted to abut against this circumferential stepped surface 7a.

[0036] The case body 3 has an inner diameter substantially equal to the outer diameter of the front end portion 6 and the body portion 7 of the movable body 2, and is cylindrical in shape with the front end open as a protrusion opening 10 for the movable body 2 and the rear end closed.

[0037] The case body 3 has an engaged portion 12 that engages with an engaging portion 9 formed on the movable body 2. In the illustrated example, the engaged portion 12 is a long guide hole 12a that is aligned in the moving direction of the movable body 2. The long guide holes 12a are formed on the left and right sides of the case body 3 corresponding to the left and right elastic pieces 9a that serve as the engaging portions 9 of the movable body 2. In the illustrated example, the long guide holes 12a are in the form of a slot that cuts into the side portion of the case body 3.

[0038] The distance between the tips of the claws 9c of the left and right elastic pieces 9a, which are the engagement parts 9 of the movable body 2, is slightly larger than the inner diameter of the case body 3. As a result, when the movable body 2 is inserted into the case body 3 from the rear end side through the protruding opening 10, the claws 9c of the elastic pieces 9a come into contact with the edge of the protruding opening 10 of the case body 3, and the elastic pieces 9a are elastically deformed in the direction of the central axis x, and this elastic deformation allows the insertion of the movable body 2 into the case body 3. Then, when the movable body 2 is inserted to a predetermined insertion position, in the illustrated example, when the claws 9c of the elastic pieces 9a are inserted into the case body 3 to a position that reaches the front end side of the guide long hole 12a, the claws 9c enter the guide long hole 12a due to the elastic return of the elastic pieces 9a. As a result, the movable body 2 and the case body 3 are combined without protruding beyond the forward position, and the movement of the movable body 2 is stably supported by the guide long hole 12a.

[0039] Although not shown in the figure, even if a guide long hole 12a as described above is provided on the movable body 2 side and an elastic piece 9a as described above (in this case, the claw portion 9c protrudes toward the central axis x) is provided on the case body 3 side, the movable body 2 and the case body 3 can be combined in the same manner as described above.

[0040] A support portion 14 for a pin 22 constituting a control mechanism 5 described later is formed on the upper portion of the case body 3. In the illustrated example, the pin 22 is formed of one end of a metal wire 22a having both ends bent in the same direction. A shaft hole 15 is formed on the rear end side of the case body 3 into which the other end 22b of the metal wire 22a can be inserted from the outside of the case body 3. A split groove 16 is formed on the front end side of the case body 3 to receive the pin 22 into the case body 3 from the outside of the case body 3 when the other end of the metal wire 22a is inserted into the shaft hole 15. The split groove 16 is formed along the arc of a virtual circle centered on the shaft hole 15. As a result, the pin 22 is assembled to the case body 3 so as to be movable in the left-right direction around the shaft hole 15 within the range of the split groove.

[0041] In the drawings, reference numeral 17 denotes a cover that is combined with the support part 14 so as to prevent the metal wire 22a combined with the case body 3 as described above from falling off. The cover 17 has grooves 17a on the left and right sides that mate with the ridges 14a that protrude laterally and continue in the front-rear direction and are formed on the left and right sides of the support part 14, and is adapted to be combined with the case body 3 so that the ridges 14a are received in the grooves 17a. The portion of the cover 17 where the grooves 17a are formed is divided into front and rear, and when the cover 17 is slid from the rear end side of the case body 3 so that the ridges 14a are received in the grooves 17a, the small protrusions 14b formed on the support part 14 side fit into the divided portions 17b, and the mounting position of the cover 17 is determined (FIG. 2).

[0042] It is sufficient for the biasing body 4 to be configured to constantly bias the movable body 2 toward the forward position, and the specific configuration may be appropriately selected as necessary. In the illustrated example, the biasing body 4 is a compression coil spring 19 interposed between the movable body 2 and the case body 3. The rear end of the compression coil spring 19 abuts against the closed rear end portion 11 of the case body 3. In the drawing, reference numeral 11a denotes a positioning portion for the cylindrical compression coil spring 19 that is formed to protrude forward from the rear end portion 11 and enters into the compression coil spring 19.

[0043] The support device 1 in this embodiment is assembled by interposing a compression coil spring 19 between the case body 3 and the movable body 2, inserting the movable body 2 from the body 7 side into the case body 3 through the protruding opening 10 of the case body 3 to a position where the engaging portion 9 engages with the engaged portion 12, and introducing a pin 22 constituting the control mechanism 5 into a guide groove 21 constituting the control mechanism 5 formed in the body 7 of the movable body 2.

[0044] This control mechanism 5 controls the movable body 2 in one cycle, which includes a temporary holding of the movable body 2 at the reference position, a first pushing of the movable body 2 from the reference position to the retracted position against the bias, movement of the movable body 2 to the advanced position by the bias after the first pushing is completed, a second pushing of the movable body 2 from the advanced position against the bias, and movement of the movable body 2 to the reference position by the bias after the second pushing is completed.

[0045] When the support device 1 is not in use, the movable body 2 temporarily held at the reference position can form part of the design surface 103 of the attachment target 100 (FIG. 1). This makes it possible to prevent the support device 1 from impairing the design of the attachment target 100 when the support device 1 is not in use. Moreover, the first pushing-in releases the temporary hold and moves the movable body 2 to the retreated position (FIG. 5). This allows a recess 102 that can be used for fitting or the like in the attachment target 100 to be formed. Moreover, by stopping the first pushing, the movable body 2 can be moved to the forward position (FIG. 3), whereby a protrusion 101 that can be used for hooking or the like on the attachment object 100 can be formed. Moreover, the second pushing can move the movable body 2 from the advanced position to the retreated position, whereby the recess 102 that can be used for fitting or the like can be formed again in the attachment target 100. Moreover, by stopping the second pushing, the movable body 2 can be moved to the reference position. This allows the movable body 2 to return to a state in which it forms a part of the design surface 103 of the attachment target 100.

[0046] In the illustrated example, when the movable body 2 is in the reference position, the pin 22 enters the recessed portion 20b of the heart cam 20 due to the bias of the compression coil spring 19, so that the movable body 2 is temporarily held in the reference position (the state in which the pin 22 is at position a in Figure 14). When the movable body 2 in the reference position is pushed in a first direction, the pin 22 hits the first guide wall 21e of the circumferential portion 21a of the guide groove 21, and the pin 22 is guided to the second lane 21c. When the pin 22 is guided to the second lane 21c, the relative movement of the pin 22 up to the front end of the second lane 21c is permitted, and as a result, the movable body 2 is moved to the retracted position (a state in which the pin 22 is at the position b in FIG. 14). When the first pushing of the movable body 2 is stopped, the movable body 2 starts to move forward due to the bias of the compression coil spring 19, and the pin 22 is guided to the third lane 21d through the underside of the heart cam 20. When the pin 22 is guided to the third lane 21d, the relative movement of the pin 22 up to the rear end of the third lane 21d is permitted, and as a result, the movable body 2 is moved to the forward position (a state in which the pin 22 is at position c in FIG. 14). When the movable body 2 in the forward position is pushed in a second direction, the pin 22 strikes the second guide wall 21f and is guided to the upper side of the heart cam 20 in the circling portion 21a, and the pin 22 is further guided to the first lane 21b by the third guide wall 21g. When the pin 22 is guided to the first lane 21b, the relative movement of the pin 22 to the front end of the first lane 21b is permitted, and as a result, the movable body 2 is again moved to the backward position (the state in which the pin 22 is at the position d in FIG. 14). When the second pushing of the movable body 2 is stopped, the movable body 2 starts to move forward due to the bias of the compression coil spring 19, and the pin 22 hits the fourth guide wall 21h and is guided into the recessed portion 20b of the heart cam 20. As a result, the movable body 2 is temporarily held at the reference position again (the state in which the pin 22 is at the position a in FIG. 14).

[0047] Although not shown in the figures, even if a pin 22 as described above is provided on the movable body 2 side and a heart cam 20 as described above is provided on the case body 3 side, the operation of the movable body 2 can be controlled in the same manner as described above.

[0048] In the first example shown in Figures 1 to 16, the case body 3 is assembled and fixed to the mounting object 100 so that the protruding opening 10 is connected to a through hole 104 formed in the mounting object 100 on the non-design surface side of the interior 105 of the mounting object 100.

[0049] In this first example, ears 18 protruding in a direction perpendicular to side portion 13 of case body 3 are formed on the upper and lower portions of the front end side of case body 3 .

[0050] In this first example, an inner circumferential wall portion 106 that borders the through hole 104 and an outer circumferential wall portion 107 that is formed with a circumferential gap between the inner circumferential wall portion 106 and the front end side of the case body 3 are formed on the non-design surface side of the attachment target 100, and boss portions 108 that enter from the front into holes 18a that penetrate the ear portions 18 in the front-rear direction are formed on the upper and lower parts of the outer circumferential wall portion 107. In this first example, the support device 1 is attached to the attachment target 100 via the case body 3 by fastening a screw to the boss portion 108 from the rear in a state where the boss portion 108 is inserted into the hole of the ear portion 18. In this example, the front end side of the movable body 2 is located within the inner circumferential wall portion 106, and is configured to close the through hole 104 of the attachment target 100 without any gaps at the reference position (FIG. 11).

[0051] In a second example shown in Figs. 17 to 21, the case body 3 has an outer flange 23 on the protruding opening 10 side, and a protruding piece 24 protruding outward rearward from the outer flange 23. The outer flange 23 is formed to go around the protruding opening 10, and has a size such that the outer flange 23 does not pass through the through hole 104 of the attachment target 100. The protruding piece 24 protrudes outward from the side part 13 of the case body 3, with a gap between the outer flange 23 and the thickness of the attachment target 100. In the example shown, the protruding piece 24 is provided at three locations at intervals in a direction going around the protruding opening 10 of the case body 3.

[0052] In this second example, a cutout portion 110 for passing the protruding piece portion 24 is formed in the attachment target 100 so as to be continuous with a through hole 104 provided in the attachment target 100. In this second example, a circumferential recess 111 is formed around the through hole 104 on the design surface 103 side of the attachment target 100. At the same time, the circumferential recess 111 is provided with three cutout portions 110 at intervals in a direction around the center of the through hole 104, the cutout portions 110 being cut in the circumferential recess 111 in a radial direction from the center of the through hole 104 to correspond to each of the three protruding piece portions 24 and allow them to be introduced (FIG. 18).

[0053] In this second example, the through hole 104 and the cutout portion 110 are utilized to introduce a portion of the case body 3 rearward of the outer flange portion 23, including the protrusion portion 24, into the attachment object 100, and then the attachment object 100 is clamped from the inside and outside between the outer flange portion 23 and the protrusion portion 24 by twisting, thereby fixing the support device 1 to the attachment object 100 via the case body 3.

[0054] In this second example, in the fixed state, the outer flange portion 23 of the case body 3 fits into the circumferential recess 111 of the attachment object 100 and is flush with the design surface 103 of the attachment object 100, and together with the front end portion 6 of the movable body 2 which is in the reference position, forms the design surface 103 of the attachment object 100 (Figure 21).

[0055] Further, on the interior 105 side of the mounting target 100, a cylindrical portion 112 is formed with a cylindrical front end communicating with the through hole 104, and the case body 3 is arranged to be accommodated within this cylindrical portion 112. On the front end side of the cylindrical portion 112, a split groove 113 is formed with one end side communicating with the notch portion 110 and extending in a direction away from the notch portion 110 in the circumferential direction, and the twisting can be performed up to a position where the protruding piece portion 24 hits an end 114 of this split groove 113 (FIG. 20).

[0056] In the case of using this second example, the support device 1 can be attached to the object 100 to be attached without using any special tools, and it can also be easily removed from the design surface 103 side of the object 100 to be attached by positioning the movable body 2 in the forward position and gripping and twisting the front end 6 side of the movable body 2.

[0057] The provision of elastic deformation characteristics to the portions of the supporting device 1 described above that should have such characteristics can be easily ensured by making all or part of the supporting device 1 an injection-molded product made of plastic.

[0058] Of course, the present invention is not limited to the above-described embodiments, but includes all embodiments that can achieve the object of the present invention. [Explanation of symbols]
