[0003] Patent Document 1: Japanese Patent Application Publication No. 2004-182215

[0004] In such cable laying devices, if the cable interferes with components other than the cable laying device, the cable's durability may be reduced. Summary of the Invention

[0005] One of the problems that the embodiments of the present invention aim to solve is to obtain a cable laying device that can improve the durability of cables.

[0006] The cable laying device according to the embodiments of the present invention is a cable laying device provided in a folding device. The folding device includes: a first frame; a second frame; a third frame; a first connecting portion that connects the first frame and the second frame in a manner that allows a folding action between the first frame and the second frame to be achieved through relative rotation between the first frame and the second frame; and a second connecting portion that connects the first frame and the third frame in a manner that allows a folding action between the first frame and the third frame to be achieved through relative rotation between the first frame and the third frame. The second connecting portion allows for switching between an unfolded state (where the first frame, the second frame, and the third frame are unfolded) and a folded state (where the first frame, the second frame, and the third frame are folded). The cable laying device also includes a support member provided in the first connecting portion. The first cable is rotatable relative to the first frame; a winding member is provided at the second connecting portion and is rotatable relative to the first frame and the third frame; a first cable is provided across the first connecting object provided at the second frame and the winding member via the support member; and a second cable is provided across the second connecting object provided at the third frame and the winding member. The first cable is longer in the folded state than in the unfolded state in terms of the length of the laying path of the first cable between the first connecting object and the winding member. In the unfolded state, the first cable is wound around the winding member at least the length corresponding to the difference between the length of the laying path in the folded state and the length of the laying path in the unfolded state. The winding member releases the first cable according to the change from the unfolded state to the folded state.

[0028] like Figures 1-5 As shown, vehicle 1 includes: a folding device 3, multiple (two in one example) wheels 5, a handle 7, a brake lever 8, a braking device 9, and a cable routing device 100. The multiple wheels 5 include a front wheel 5F and a rear wheel 5R. Vehicle 1 can be in the unfolded state ( Figure 1 , Figure 2 , Figure 4 ) and folded state ( Figure 3 , Figure 5 The directions change between ) . From now on, unless otherwise specified, the forward / backward, left / right, and up / down directions are the forward / backward, left / right, and up / down directions of the deployed vehicle 1. The cable laying device 100 is also referred to as a cable device.

[0029] <Folding Device>

[0030] Figure 6 This is an illustrative and schematic cross-sectional view showing a portion of the folding device according to the embodiment. Figure 7 This is an illustrative and schematic cross-sectional view showing a portion of the folding device according to the embodiment. Figure 8 This is an illustrative and schematic side view of a portion of the folding device vehicle according to the embodiment. Figure 9 This is an illustrative and schematic side view of a portion of the folding device vehicle according to the embodiment.

[0031] like Figures 1-9 As shown, the folding device 3 includes a base frame 11, a front frame 13, a rear frame 15, a front connecting part 17F, a rear connecting part 17R, and an input part 21. The base frame 11, the front frame 13, and the rear frame 15 constitute the frame 10. Furthermore, the base frame 11, the front frame 13, and the rear frame 15 may each be composed of multiple components or a single component.

[0032] like Figure 1 , Figure 6 and Figure 7 As shown, as an example, the base frame 11 has two base members 23L and 23R. The two base members 23L and 23R are arranged at intervals in the left-right direction and are joined together.

[0033] like Figure 1 and Figure 6As shown, the front frame 13 extends forward from the base frame 11. As an example, the front frame 13 has a cylindrical member 13A and two plates 13L and 13R. A handle 7 is fixed to the upper end of the cylindrical member 13A. The two plates 13L and 13R are connected to the cylindrical member 13A at intervals in the left-right direction and are interlocked. The two plates 13L and 13R are connected to two base members 23L and 23R. A front wheel 5F is provided on the front frame 13.

[0034] like Figure 1 and Figure 7 As shown, as an example, the rear frame 15 has two side rails 29L and 29R and two contact portions 30L and 30R. The two side rails 29L and 29R are arranged spaced apart in the left-right direction and are engaged with each other. The two side rails 29L and 29R are made of, for example, metal. The two contact portions 30L and 30R are located at the rear ends of the two side rails 29L and 29R. The two contact portions 30L and 30R are made of, for example, rubber or synthetic resin. Figure 2 As shown, in the unfolded state, with each wheel 5 in contact with the ground 200, the two contact portions 30L and 30R separate from the ground 200. Figure 3 As shown, in the folded state, with the contact portions 30L and 30R in contact with the ground 200, the wheel 5 mounted on one of them separates from the ground 200, and the vehicle 1 stands upright. A rear wheel 5R is mounted on the rear frame 15. The ground 200 is an example of a surface.

[0035] like Figures 1-5 As shown, the front connector 17F connects the base frame 11 and the front frame 13 in a manner that allows and prevents a folding action between the base frame 11 and the front frame 13. Figure 6 As shown, specifically, the front connecting part 17F includes a first folding part 33F and a first adjuster 35F.

[0036] The first folding section 33F connects the base frame 11 and the front frame 13 in a manner that allows folding between them via relative rotation about the first rotation center axis Ax1. The first adjuster 35F switches between a permitted state (allowing folding between the base frame 11 and the front frame 13) and a prohibited state (prohibiting folding) via rotation of the first rotating member 39F. The permitted state is also referred to as the unlocked state, and the prohibited state is also referred to as the locked state.

[0037] The first folding part 33F has a front axle body 37F. The first folding part 33F connects the base frame 11 and the front frame 13 through the front axle body 37F in such a way that the folding action between the base frame 11 and the front frame 13 can be realized by the relative rotation between the base frame 11 and the front frame 13 about the first rotation center axis Ax1.

[0038] The first adjuster 35F has a structure similar to, for example, that of known adjusters used in automobile seats, etc. For example, the first adjuster 35F includes a first rotating member 39F, two connecting members 41F and 43F, an engaging mechanism (locking mechanism), and a spring member. Connecting member 41F is connected (fixed) to the base frame 11, and connecting member 43F is connected (fixed) to the front frame 13. The first rotating member 39F can allow and prohibit relative rotation between the two connecting members 41F and 43F by rotating about a first rotation center axis Ax1. That is, the first adjuster 35F switches between a permitted state that allows folding action between the base frame 11 and the front frame 13 and a prohibited state that prohibits such folding action by rotating the first rotating member 39F. The state in which the engagement (locking mechanism) is released, allowing relative rotation between the connecting members 41F and 43F, is a permitted state. The state in which the engagement (locking mechanism) is formed, preventing relative rotation between the connecting members 41F and 43F, is a prohibited state.

[0039] like Figures 1-5 As shown, the rear connector 17R connects the base frame 11 and the rear frame 15 in a manner that allows for a folding action between the base frame 11 and the rear frame 15, and permits and prohibits this folding action. Figure 7 As shown, specifically, the rear connector 17R includes a second folding portion 33R and a second adjuster 35R.

[0040] The second folding section 33R connects the base frame 11 and the rear frame 15 in a manner that allows folding between the base frame 11 and the rear frame 15 through relative rotation about the second rotation center axis Ax2. The second adjuster 35R switches between a permitted state that allows folding between the base frame 11 and the front frame 13 and a prohibited state that prohibits folding by rotating the second rotating member 39R.

[0041] The second folding section 33R has a rear axle 37R. The second folding section 33R connects the base frame 11 and the rear frame 15 through the rear axle 37R in a manner that allows the base frame 11 and the rear frame 15 to fold by means of relative rotation about the second rotation center axis Ax2.

[0042] Similar to the first regulator 35F, the second regulator 35R has a known regulator structure. For example, the second regulator 35R has a second rotating member 39R, two connecting members 41R and 43R, an engaging mechanism (locking mechanism), and a spring member. Connecting member 41R is connected (fixed) to the base frame 11, and connecting member 43R is connected (fixed) to the rear frame 15. The second rotating member 39R, by rotating about a second rotation center axis Ax2, can allow and prohibit relative rotation between the two connecting members 41R and 43R. That is, the second regulator 35R switches between a permitted state that allows folding action between the base frame 11 and the rear frame 15 and a prohibited state that prohibits such folding action by rotating the second rotating member 39R.

[0043] <Folding Action Linkage Unit>

[0044] like Figure 8 As shown, the folding device 3 also includes a folding action linkage unit 45. The folding action linkage unit 45 links the folding action between the base frame 11 and the front frame 13 and the folding action between the base frame 11 and the rear frame 15.

[0045] Specifically, the folding action linkage unit 45 has a front rotating member 49F (first linkage rotating member), a rear rotating member 49R (second linkage rotating member), and a chain 51 (linkage member).

[0046] The front rotating member 49F is capable of rotating about the first rotation center axis Ax1 relative to the base frame 11, together with the front frame 13 (as an integral part). Specifically, the front rotating member 49F is integrally provided with and rotates integrally with the front axle body 37F. The front rotating member 49F is, for example, a sprocket (gear). Furthermore, the front axle body 37F and the front frame 13 are fixed together by bolts or the like (not shown) and rotate integrally about the first rotation center axis Ax1.

[0047] The rear rotating member 49R is capable of rotating together with the rear frame 15 relative to the base frame 11 about the second rotation center axis Ax2. Specifically, the rear rotating member 49R is integrally disposed with the rear axle 37R and rotates integrally with the rear axle 37R. The rear rotating member 49R is, for example, a sprocket (gear).

[0048] Chain 51 is attached to the front rotating component 49F and the rear rotating component 49R, so that the front rotating component 49F and the rear rotating component 49R are linked.

[0049] <Rotary linkage>

[0050] like Figure 9As shown, the folding device 3 also includes a rotation linkage 47. The rotation linkage 47 links the first rotating member 39F of the first regulator 35F with the second rotating member 39R of the second regulator 35R. That is, the rotation linkage 47 synchronizes the state (allowed state, prohibited state) of the first regulator 35F with the state (allowed state, prohibited state) of the second regulator 35R.

[0051] Specifically, the rotary linkage 47 includes a parallel linkage mechanism 65 and a drive unit 67.

[0052] The parallel linkage mechanism 65 links the first rotating member 39F and the second rotating member 39R. The parallel linkage mechanism 65 has a front release member 69F, a rear release member 69R, a connecting rod 71, and a Bell crank 73. The connecting rod 71 is also referred to as the first movable member, and the Bell crank 73 is also referred to as the second movable member.

[0053] For the front release member 69F, one end is fixed to the first rotating member 39F, and the other end is connected to one end (front end) of the connecting rod 71 in a manner that allows relative rotation.

[0054] For the rear release member 69R, one end is fixed relative to the second rotating member 39R, and the other end is connected to the other end (rear end) of the connecting rod 71 in a manner that allows relative rotation.

[0055] The Bell crank 73 has an input arm for receiving operating force from the input section 21 and a connecting arm that is rotatably connected to the connecting rod 71. The Bell crank 73 is supported by the base frame 11 so that it can rotate about a predetermined return axis.

[0056] In the above structure, the Bell crank 73 and the parallel linkage mechanism 65 are in a locked position, which prohibits the first rotating member 39F and the second rotating member 39R, due to the elastic force of the spring members built into the first rotating member 39F and the second rotating member 39R respectively. If the Bell crank 73 rotates from this position in the release direction, the connecting rod 71 moves parallel to the Bell crank 73. This movement of the connecting rod 71 causes the front release member 69F to rotate around the first rotating member 39F, and the rear release member 69R to rotate around the second rotating member 39R, thus causing the second rotating member 39R to rotate. Therefore, the first rotating member 39F and the second rotating member 39R change from the prohibited state to the permitted state. The positions of each part when the first rotating member 39F and the second rotating member 39R are in the prohibited state are called the prohibited positions, and the positions of each part when the first rotating member 39F and the second rotating member 39R are in the permitted state are called the permitted positions. As described above, the connecting rod 71 can change between the permitted and prohibited states of the first regulator 35F and the second regulator 35R by moving parallel to the direction in which the first rotating member 39F and the second rotating member 39R rotate. More specifically, the connecting rod 71 connects the first rotating member 39F and the second rotating member 39R, and is connected to each of the first rotating member 39F and the second rotating member 39R in a manner that allows relative rotation. By moving parallel to the direction in which the first rotating member 39F and the second rotating member 39R rotate, the connecting rod 71 can change between the permitted and prohibited states of the first regulator 35F and the second regulator 35R. Furthermore, in this embodiment, when the connecting rod 71 is moved by the Bell crank 73, the amount of rotation of the Bell crank 73, the amount of rotation of the first rotating member 39F, and the amount of rotation of the second rotating member 39R are the same.

[0057] The drive unit 67 has a release member 75. The release member 75 is supported by the base frame 11 and is rotatable about a predetermined rotation center axis. One end (upper end) of the release member 75 is connected to the operation member 81 of the input unit 21.

[0058] <Input Section>

[0059] like Figure 9 As shown, the input unit 21 has an operating member 81. The input unit 21 is connected to the first regulator 35F and the second regulator 35R via a drive unit 67 and a parallel linkage mechanism 65, causing the first rotating member 39F of the first regulator 35F and the second rotating member 39R of the second regulator 35R to rotate. That is, the input unit 21 operates the first regulator 35F and the second regulator 35R.

[0060] The operating component 81 is supported by the base frame 11 so that it can rotate.

[0061] In the above structure, in the deployed state of vehicle 1, the first adjuster 35F and the second adjuster 35R are in a prohibited state. If the operating member 81 is pulled upward from this state, the first adjuster 35F and the second adjuster 35R change from the prohibited state to the permitted state. If the operating member 81 is pulled upward further from this state, the base frame 11 folds with the front frame 13 and the base frame 11 folds with the rear frame 15.

[0062] <Braking System>

[0063] Figure 10 This is an illustrative and schematic side view of a portion of the folding device vehicle according to an embodiment. For example... Figure 1 and Figure 10 As shown, braking system B includes a brake lever 8, a braking device 9, and a cable routing device 100. Braking system B is also referred to as a braking mechanism.

[0064] The brake lever portion 8 is provided on the handle 7. The brake lever portion 8 has a base portion 8a fixed to the handle 7 and a handle member 8b supported by the base portion 8a and capable of rotation.

[0065] A braking device 9 is installed on the rear wheel 5R. The braking device 9 is, for example, a drum brake, but is not limited to this. The braking device 9 includes a braking part 9a capable of braking the rear wheel 5R and a lever member 9b for operating the braking part 9a. The braking device 9 is connected to the brake lever part 8 via a cable routing device 100.

[0066] <Cable Laying Device>

[0067] Figure 11 This is an illustrative and schematic side view of a portion of the folding device vehicle according to the embodiment. Figure 12 This is an explanatory diagram used to illustrate the folding action of the folding device vehicle in the embodiment. Figure 13 This is an explanatory diagram used to illustrate the length of the laying path of the first cable of the folding device vehicle in the embodiment. Figure 14 This is an explanatory diagram used to illustrate the first cable and the second cable in the folding operation of the folding device vehicle according to the embodiment.

[0068] like Figure 10 and Figure 11 As shown, the cable laying device 100 includes a first pulley 101, a second pulley 102, a first cable 103, a second cable 104, a first housing 105, a second housing 106, and a third housing 107. Figure 4 The first pulley 101 is an example of a support member, and the second pulley 102 is an example of a winding member.

[0069] like Figure 6As shown, the first pulley 101 is provided at the front connecting portion 17F. Specifically, the first pulley 101 is rotatable relative to the base frame 11 and the front frame 13. For example, the first pulley 101 is supported by the first rotating member 39F in a manner that allows it to rotate about the first rotation center axis Ax1. Alternatively, the first pulley 101 may be fixed to the base frame 11, for example. A groove 101a is provided on the first pulley 101. The first cable 103 is inserted into the groove 101a.

[0070] like Figure 7 As shown, the second pulley 102 is provided at the rear connecting part 17R and can rotate relative to the base frame 11 and the rear frame 15. For example, the second pulley 102 is supported by the second rotating member 39R in such a way that it can rotate about the second rotation center axis Ax2. The second pulley 102 has two slots 102a and 102b spaced apart in the left-right direction. The first cable 103 is placed in slot 102a and the second cable 104 is placed in slot 102b.

[0071] like Figure 10 As shown, the first cable 103 is spanned between the brake lever portion 8 and the second pulley 102 located on the front frame 13 via the first pulley 101. Specifically, one end 103a of the first cable 103 is fixed to the rod member 8b, and the other end 103b of the first cable 103 is fixed to the second pulley 102. The portion of the first cable 103 that contacts the first pulley 101 is supported by the first pulley 101. The first cable 103 is a brake cable.

[0072] The second cable 104 spans between the braking device 9 located at the rear frame 15 and the second pulley 102. Specifically, one end 104a of the second cable 104 is fixed to the second pulley 102, and the other end 104b of the second cable 104 is fixed to the rod member 9b. The second cable 104 is a braking cable.

[0073] The first housing 105 is cylindrical and is supported (fixed) to the base frame 11. A first cable 103 is arranged inside the first housing 105 along the base frame 11. The first housing 105 is capable of rotating relative to the front frame 13 as an integral part of the base frame 11.

[0074] The second housing 106 is cylindrical and is supported (fixed) to the front frame 13. A first cable 103 is arranged inside the second housing 106 along the front frame 13. The second housing 106 is capable of rotating relative to the base frame 11 as an integral part of the front frame 13.

[0075] like Figure 4As shown, the third housing 107 is cylindrical and is supported (fixed) to the rear frame 15. A second cable 104 is arranged inside the third housing 107 along the rear frame 15. The third housing 107 is capable of rotating relative to the base frame 11 as an integral part of the rear frame 15.

[0076] Figure 6 and Figure 7 The radius R1 of the first pulley 101 is shown. Figure 6 ) and the radius R2 of the second pulley 102 ( ) Figure 7 The radius R1 of the first pulley 101 (). Figure 6 The radius R2 of the second pulley 102 is () Figure 7 The ratio between the base frame 11 and the front frame 13 during the change from the unfolded state to the folded state is set based on the ratio between the relative rotation amount between the base frame 11 and the rear frame 15 during the change from the unfolded state to the folded state. Here, as an example, the radius R1 of the first pulley 101 is the length from the center of the first pulley 101 (the first rotation center axis Ax1) to the bottom of the groove 101a. Furthermore, the radius R2 of the second pulley 102 is the length from the center of the second pulley 102 (the second rotation center axis Ax2) to the bottom of the grooves 201a and 201b.

[0077] Here, Figure 12 The diagram shows the state of the folding device 3 (vehicle 1) changing from state F12a to state F12b. State F12a is the unfolded state, and state F12b is the folded state. Furthermore, Figure 12 In the diagram, arrow Y1 visually indicates the magnitude of the relative rotation between the base frame 11 and the front frame 13 (hereinafter referred to as the first relative rotation) during the change from the unfolded state to the folded state, and arrow Y2 visually indicates the magnitude of the relative rotation between the base frame 11 and the rear frame 15 (hereinafter referred to as the second relative rotation) during the same process. The first relative rotation (arrow Y1) is, for example, 136 degrees. The second relative rotation (arrow Y2) is, for example, 218 degrees. That is, the second relative rotation is 1.6 times the first relative rotation.

[0078] The radius R1 of the first pulley 101 ( Figure 6 The radius R2 of the second pulley 102 is set as ( Figure 7The radius R1 of the first pulley 101 is 1.6 times that of the second pulley 102. Thus, the ratio between the radius R1 of the first pulley 101 and the radius R2 of the second pulley 102 is set based on the ratio between the relative rotation amount (arrow Y1) between the base frame 11 and the front frame 13 during the change from the unfolded state to the folded state, and the relative rotation amount (arrow Y2) between the base frame 11 and the rear frame 15 during the change from the unfolded state to the folded state. Here, as an example, the radius R1 of the first pulley 101 is the length from the center of the first pulley 101 (the first rotation center axis Ax1) to the bottom of the groove 101a. Furthermore, the radius R2 of the second pulley 102 is the length from the center of the second pulley 102 (the second rotation center axis Ax2) to the bottom of the grooves 201a and 201b.

[0079] Figure 13 The diagram shows states F13a and F13b. State F13a is the unfolded state, and state F13b is the folded state. Figure 13 As shown, if the base frame 11 rotates 136 degrees relative to the front frame 13, the first pulley 101 also rotates 136 degrees along with the base frame 11. The first outer shell 105 and the second outer shell 106 are fixed to the base frame 11 and the front frame 13, respectively. Therefore, by rotating the base frame 11 due to the folding, the length of the routing path of the first cable 103 between the first outer shell 105 and the second outer shell 106 changes from length L1 (state F13a) to length L2 (state F13b). Based on the radius R1 of the first pulley 101, the change in the length of the routing path of the first cable 103 (hereinafter also referred to as the cable path length) is length L2 - length L1 = 136 / 360 × 2πR1. At least this change in length results in the first cable 103 of varying lengths being wound around the second pulley 102 in the unfolded state. That is, in the unfolded state, a first cable 103 of at least the length corresponding to the difference between the length of the laying path in the folded state and the length of the laying path in the unfolded state is wound around the second pulley 102.

[0080] Figure 14 The diagram shows states F14a, F14b, F14c, and F14d. State F14a is the unfolded state. State F14b is the folded state. State F14c is shown as state F14a (unfolded state) with reference to base frame 11. State F14d is shown as state F14b (folded state) with reference to rear frame 15.

[0081] like Figure 14As shown, through the folding operation, the base frame 11 and the rear frame 15 rotate relative to each other by only 136 × 1.6 = approximately 218 degrees about the second rotation center axis, changing from state F14a to state F14b. At this time, in the unfolded state, the first cable 103 is fixed to the second pulley 102 in a state where it is wound up as described above (length L2 - length L1) or more (state F14a). If the base frame 11 rotates only 136 degrees relative to the front frame 13, the cable path length is extended only by (length L2 - length L1), therefore, the first cable 103 is released (pulled out) from the second pulley 102 by (length L2 - length L1).

[0082] Based on the ratio (1.6) between the relative rotation amount formed by the front connecting part 17F and the relative rotation amount formed by the rear connecting part 17R, the radius R2 of the second pulley 102 is set to the radius R1 / 1.6 of the first pulley 101. Therefore, the second pulley 102 rotates only 1.6 times the rotation angle (136 degrees) of the first pulley 101, which is 218 degrees (state F14a → state F14c). The rotation at the front connecting part 17F and the rear connecting part 17R is linked by the folding action linkage part 45 at a rotation amount ratio of 1.6, so the rear frame 15 rotates 218 degrees relative to the base frame 11. This rotation is synchronized with the rotation of the second pulley 102.

[0083] As described above, as a result, the second pulley 102 and the rear frame 15 rotate only 218 degrees simultaneously. Therefore, the cable path length of the second cable 104 connecting the braking device 9, which is fixed to the rear frame 15, to the second pulley 102 remains unchanged. Consequently, the second cable 104 connected to the braking device 9 is not pulled due to the folded state, and the braking device 9 is not activated. This can also be understood from the fact that the position of the end of the second cable 104 on the second pulley 102 remains unchanged in states F14a and F14d.

[0084] like Figure 10 As shown, if the brake lever 8b is gripped by the occupant in the deployed state, the first cable 103 is pulled by a length L3mm. Consequently, the second pulley 102 is pulled around by the first cable 103. Figure 10 The second pulley 102 rotates counterclockwise, causing the second cable 104 to be pulled only by the amount of L3. This pulls the lever member 9b of the braking device 9, thus activating the braking device 9.

[0085] As described above, in this embodiment, the base frame 11 rotates about the first rotation center axis Ax1, and the rear frame 15 rotates about the second rotation center axis Ax2 by only 1.6 times the rotation of the base frame 11. This rotational action maintains a 1.6-fold relationship due to the folding action linkage 45. In the unfolded state, the rear frame 15 is parallel to the ground 200, but through the folding operation, the angle between the rear frame 15 and the ground 200 changes to 74 degrees. Therefore, the contact portions 30L and 30R of the rear frame 15, which are not grounded on the ground 200 in the unfolded state, are grounded on the ground 200. The contact portions 30L and 30R are spaced apart in the vehicle width direction and grounded relative to the ground 200 respectively; therefore, the vehicle 1 itself stands upright ( Figure 3 ).

[0086] <Summary>

[0087] As described above, the cable laying device 100 of this embodiment is provided on the folding device 3. The folding device 3 includes a base frame 11 (first frame), a front frame 13 (second frame), a rear frame 15 (third frame), a front connecting part 17F (first connecting part), and a rear connecting part 17R (second connecting part). The front connecting part 17F connects the base frame 11 and the front frame 13 in a manner that allows the base frame 11 and the front frame 13 to fold together by relative rotation between them. The rear connecting part 17R connects the base frame 11 and the rear frame 15 in a manner that allows the base frame 11 and the rear frame 15 to fold together by relative rotation between them. The folding device 3 can switch between an unfolded state in which the base frame 11, the front frame 13, and the rear frame 15 are unfolded, and a folded state in which the base frame 11, the front frame 13, and the rear frame 15 are folded. The cable laying device 100 includes a first pulley 101 (support member), a second pulley 102 (winding member), a first cable 103, and a second cable 104. The first pulley 101 is located at the front connecting portion 17F and is rotatable relative to the base frame 11. The second pulley 102 is located at the rear connecting portion 17R and is rotatable relative to both the base frame 11 and the rear frame 15. The first cable 103 is laid across the brake lever portion 8 mounted on the front frame 13 and the second pulley 102 via the first pulley 101. The second cable 104 is laid across the brake device 9 (second coupling object) mounted on the rear frame 15 and the second pulley 102. The length of the laying path of the first cable 103 between the brake lever portion 8 and the second pulley 102 is longer in the folded state than in the unfolded state. In the unfolded state, a first cable 103, with a length corresponding to at least the difference between the length of the laying path in the folded state and the length of the laying path in the unfolded state, is wound onto a second pulley 102. The second pulley 102 releases the first cable 103 according to the change from the unfolded state to the folded state.

[0088] According to this structure, in the unfolded state, a first cable 103 of at least the length corresponding to the difference between the length of the laying path in the folded state and the length of the laying path in the unfolded state is wound around the second pulley 102, thus preventing the first cable 103 from becoming loose. Therefore, according to the above structure, in the unfolded state, the first cable 103 is less likely to interfere with objects other than the cable laying device 100, thereby improving the durability of the first cable 103.

[0089] Furthermore, the cable laying device 100 includes a first housing 105 and a second housing 106. The first housing 105 is cylindrical and supported by a base frame 11, and the cable laying device 100 has a first cable 103 laid inside along the base frame 11, and is able to rotate relative to the front frame 13 as an integral part of the base frame 11. The second housing 106 is cylindrical and supported by the front frame 13, and the second housing 106 has a first cable 103 laid inside along the front frame 13, and is able to rotate relative to the base frame 11 as an integral part of the front frame 13.

[0090] According to this structure, the housing in which the first cable 103 is internally arranged is divided into a first housing 105 and a second housing 106, thus making it easy to bend the first cable 103. In addition, no excessive bending force is applied to the first housing 105 and the second housing 106.

[0091] Furthermore, the supporting member is the first pulley 101. The winding member is the second pulley 102. The ratio between the radius of the first pulley 101 and the radius of the second pulley 102 is set according to the ratio between the relative rotation between the base frame 11 and the front frame 13 during the change from the unfolded state to the folded state and the relative rotation between the base frame 11 and the rear frame 15 during the change from the unfolded state to the folded state.

[0092] According to this structure, the tension of the first cable 103 is less likely to become excessive. Therefore, the durability of the first cable 103 can be improved.

[0093] In addition, vehicle 1 is equipped with cable laying device 100, folding device 3, and wheels 5 respectively installed on front frame 13 and rear frame 15.

[0094] According to this structure, the durability of the first cable 103 of vehicle 1 can be improved.

[0095] Furthermore, the folding device 3 includes contact portions 30L and 30R provided on one of the front frame 13 and the rear frame 15. In the unfolded state, with each wheel 5 in contact with the ground 200 (surface, plane), the two contact portions 30L and 30R separate from the ground 200. In the folded state, with the contact portions 30L and 30R in contact with the ground 200, the wheel 5 provided on one of them separates from the ground 200, and the vehicle 1 stands upright.

[0096] According to this structure, there is no need to set up a support frame for the vehicle 1 to stand upright. Therefore, the vehicle 1 can be simplified.

[0097] In addition, the first cable 103 is housed inside the base frame 11 and the front frame 13, and the second cable 104 is housed inside the base frame 11 and the rear frame 15.

[0098] Based on this structure, the appearance design (aesthetics) of vehicle 1 can be improved.

[0099] Furthermore, in the above embodiment, an example is shown where the first coupling is the brake lever portion 8 and the second coupling is the braking device 9, but this is not a limitation. For example, the first coupling could be a brake button and the second coupling could be an electric braking device. In this case, the first cable 103 and the second cable 104 are each wires and are electrically connected to each other.

[0100] Furthermore, while the above embodiment illustrates an example of the folding device 3 being applied to vehicle 1, it is not limited thereto. The folding device 3 can also be applied to various other devices, equipment, etc.

[0101] The above embodiments of the present invention are illustrated, but they are merely examples and not intended to limit the scope of the invention. The above embodiments can be implemented in various other ways, and various omissions, substitutions, combinations, and modifications can be made without departing from the spirit of the invention. Furthermore, the specifications (construction, type, orientation, shape, size, length, width, thickness, height, quantity, arrangement, position, material, etc.) of various structures, shapes, display elements, etc., can be appropriately modified for implementation.
