<Vehicles with protective equipment (bicycles with protective equipment)>
FIG. 1 is a diagram showing a vehicle with protective equipment according to an embodiment of the present invention. FIG. 2 is a diagram for explaining a wire rod. 3 and 4 are partially enlarged views of FIG. 1 for explaining the protective equipment. The vehicle with protective equipment 10 includes a vehicle main body (hereinafter, also simply referred to as “main body”) 20 and a protective device 30 attached (attached) to the vehicle main body 20. The protective device 30 is configured to include a wire having loop-shaped elasticity, and is located on the front side of the vehicle body 20. Preferably, the protective device 3 is detachably attached (attached) to the vehicle body 20.

In the present embodiment, the vehicle body is a two-wheeled vehicle or a three-wheeled vehicle, and the vehicle with protective equipment 10 is, for example, a bicycle 11 with protective equipment. The bicycle 11 with a protective device includes a main body 21 and a protective device 31 attached to the main body 21. Known techniques are appropriately used for the configuration of the main body 21, and detailed description thereof will be omitted here.

The bicycle with protective device 11 can include a plurality of protective devices 31, for example, a front protective device 31a in the front portion, a rear protective device 31b in the rear portion, a finger protective device 31c, a front wheel upper protective device 31d, and a rear wheel upper protective device 31d. The protective device 31e, the front wheel side protective device 31f of the side portion, and the rear wheel side protective device 31g can be included. The protective bicycle 11 includes one of these protective devices or two or more protective devices. The protective tool 31 is configured to include an elastic wire rod 4.

The wire rod 4 is made of a metal wire rod having elasticity and preferably a circular cross section, for example, a wire such as stainless steel, piano wire, brass wire, precious metal wire, or precious metal plated wire. However, the present invention is not limited to this, and a wire rod having a polygonal cross section such as a quadrangle or a hexagon may be used. The thickness of the wire (face-to-face width in the case of a polygon) is, for example, a lower limit of 1.0 mm, preferably 1.6 mm, and more preferably 2.0 mm in a bicycle or the like. The upper limit is 8.0 mm, preferably 6.0 mm, and more preferably 4.0 mm. For motorcycles, automobiles, and the like that weigh more than 100 kg, the lower limit is 3.0 mm, preferably 3.2 mm, and more preferably 3.5 mm. The upper limit is 12 mm, preferably 10.0 mm, more preferably 8.0 mm.

The wire rod 4 may have a coating layer by coating the surface of the wire rod with nylon, silicon, Teflon or the like, or by plating or the like. The wire rod 4 may be further formed of a material such as a plastic resin such as nylon (including those containing carbon fiber, Kevlar (registered trademark), etc.). Further, the thickness may be thickened at both ends and gradually reduced toward the center. Even if the term "wire" or "wire" is used in the following description, it does not mean that the wire is limited to a wire, and any known suitable elastic wire may be used.

When a plurality of wire rods 4 are included, the thicknesses of the wire rods may be the same, or some or all of them may be different in thickness. Further, the elastic force of the wire rod 4 may be the same among the wire rods, or may be partially or completely different from each other.

The wire rod 4 has a loop shape. As shown in FIG. 2, as an example, the wire rod 4 has an unclosed loop shape, for example, a substantially U-shape or a C-shape. The loop shape may be formed such that one wire is bent and, for example, starts from one end 403 and is folded back at substantially the center so that the other end 403 returns to the position where the one end 403 is aligned with the one end 403. It may be formed of a material such as resin. The wire rod 4 includes both end portions 403, a central tip 401, and both limbs 402 extending between them.

In this way, by using an elastic wire to form a loop, the impact force from the outside is changed to elastic energy to alleviate the impact, and the wire is safe because it does not break even if it bends. Furthermore, since the part that receives the impact is loop-shaped, it is difficult to get caught and does not stick, so it is safe.

As shown in FIG. 2A, as an example, the wire rod 4 is semi-elliptical or U-shaped in the upward view as shown in the upper figure, and substantially linear in the lateral view as shown in the lower figure. be.

As shown in FIG. 2B, as an example, the wire rod 4 has a substantially C-shape in the upward view and a linear limb 402 in the lateral view as shown in the lower figure. The vicinity of the tip 401 is arcuate.

As shown in FIG. 2C, as an example, as shown in the above figure, the wire rod 4 has a substantially U-shaped or C-shaped shape as a whole when viewed upward, and the latter half of both limbs 402 is directed backward. It has a shape that opens to the outside. As shown in the figure below, the wire rod 4 has a curved shape in a lateral view.

As shown in FIG. 2 (d), as an example, the wire rod 4 has a substantially U-shape or C-shape that is asymmetrical as a whole in the upward view as shown in the upper figure, and is lateral as shown in the lower figure. It is a curved shape with a dent in the visual sense.

The shape of the wire rod 4 is merely an example, and may have various shapes. Each protective device of the bicycle with protective device 11 is configured to include a substantially U-shaped or C-shaped wire rod 4 having such elasticity. Hereinafter, each protective device 31 will be described in detail.

As shown in FIG. 3, the front protector 31a is attached around the handle 211. The front protective tool 31a is configured to include a wire rod group formed by arranging a plurality of wire rods 4 at predetermined intervals. As an example, a wire rod group formed by arranging three wire rods (41a, 42a, 43a) having substantially U-shaped or C-shaped loops of different sizes at predetermined intervals is included.

Explaining each wire rod in the wire rod group of the front protective tool 31a by taking the wire rod 41a as an example, both end portions 403 are attached to the handle 211 so that both end portions 403 are located above and the tip end 401 is located below. The wire rod mounting structure will be described later. As shown in the examples described later, the wire rod may be detachably attached to the vehicle body. Further, as will be described later with reference to FIG. 26, the wire rod 4 may be rotatably attached. A known technique may be used as appropriate.

The wire rod group of the front protective tool 31a is an inner / outer overlapping type wire rod group in which each wire rod is arranged (for example, concentrically) so that the loop of the small wire rod is included in the loop of the large wire rod in the loop surface direction. The wire rod group of the front protective tool 31a is a convex or concave wire rod group in which each wire rod is arranged back and forth or vertically at predetermined intervals in a direction orthogonal to the loop surface. In the following, such a wire rod group will be referred to as an "inner-outer stacking type concave wire rod group" or an "inner-outer stacking type convex wire rod group".

More specifically, in the front protective tool 31a, in the loop surface direction (in front view), the loops of the respective wire rods are arranged so as to be overlapped inside and outside, and the loop of the second large wire rod 42a is included in the loop of the maximum wire rod 41a. , The loop of the third large wire rod (minimum wire rod) 43a is arranged so as to be included in the loop of the second large wire rod 42a. Further, in the direction orthogonal to the loop plane (in the lateral view), the wires are arranged back and forth at predetermined intervals, the maximum wire 41a is arranged at the front, the minimum wire 43a is arranged at the rearmost, and the second wire is arranged. The large wire rod 42a is arranged between them.

As a result, the front protective tool 31a is formed in a concave shape (recessed shape) recessed from the front side to the back side, and has a concave internal space in the front. As shown in the figure, when the handle 211 has an inclined portion between the central portion and both end portions (the portion that fits with the grip), the front protective tool can be attached by attaching the second large wire rod and the maximum wire rod along the inclined portion. The 31a can be easily formed in a concave shape.

The size of each wire in the wire group can be set according to the size of the main body. As an example, the maximum wire rod 41a has a vertical width (width from the end to the tip) such that the tip is substantially the same as the lower end of the head 2121 of the frame 212 or slightly lower than the head 2121, and both ends of the handle 211. It has a width narrower than the portion (width between both ends). The number of wire rods constituting the wire rod group can be appropriately set according to the size and application of the main body. As an example, the lower limit of the number of wires is, for example, one, preferably two, and the upper limit is, for example, eight, preferably six.

The front protective device 31a is located in front of the bicycle body 21 and acts as a shield to protect the driver and the contact person. More specifically, the front protector 31a is arranged in the center of the handle 211, the stem 2111 supporting the handle 211, and the front of the head 2121 of the frame 212 connected to the stem 2111 to operate a contact object or a contact person. It reduces contact with the person, cushions the impact and protects the driver. In addition, the contact of the contact with the bicycle body is reduced, the impact is mitigated, and the contact is protected.

Since the front protective tool 31a has a gap between the wires in the loop surface direction, here in the lateral direction (direction orthogonal to the front-rear direction and the vertical direction (left-right direction)), the air resistance is increased even if a headwind blows. There is no such thing. Further, since there is a gap between the wires in the front-rear direction as well, the risk of falling does not increase even in the case of a crosswind. Further, the front protective device 31a has advantages such as light weight, easy cleaning, and easy manufacturing.

Since the front protective tool 31a is formed in a concave shape, when a block-shaped contact object such as a spherical body comes into contact with the front protective tool 31a, it can be temporarily received in the inner space while repelling, and at this time, the tip 401 of each wire rod is downward. Support the contact with. The contact object leaves the front protective device 31a while receiving the elastic force, but if the front wheel upper protective device 31d is provided as described later, the contact with the front wheel can be reduced and the impact can be further mitigated. Further, when a plate-shaped contact object comes into contact with the wire rod, the wire rods arranged one after the other are sequentially contacted to alleviate the impact.

The rear protector 31b is attached to the saddle 214. As an example, the rear protective tool 31b is an inner / outer overlapping type convex wire rod in which three wire rods (41b, 42b, 43b) having substantially U-shaped or C-shaped loops of different sizes are arranged at predetermined intervals. It is a group.

More specifically, in the rear protective tool 31b, in the loop surface direction (in rear view), the loops of the respective wire rods are arranged in and out of the loop, and the loop of the second large wire rod 42b is included in the loop of the maximum wire rod 41b. , The loop of the third large wire rod (minimum wire rod) 43b is arranged so as to be included in the loop of the second large wire rod 42b. Further, in the rear protective tool 31b, in the direction orthogonal to the loop surface, the wire rods are arranged back and forth, the maximum wire rod 41b is arranged in the frontmost direction, the minimum wire rod 43b is arranged in the rearmost direction, and the second large wire rod 42b is arranged. Are arranged in the meantime.

Explaining each wire rod in the wire rod group by taking the wire rod 42b as an example, both end portions 403 are attached to the rear lower end of the saddle 214 so that the tip end 401 is located above and both end portions 403 are located below. Both limbs 402 of each wire rod are curved rearward and upward, and the rear protective device 31b is configured to surround the space above the rear of the saddle 214 and cover the driver from the rear.

As a result, the rear protective tool 31b is configured in a convex shape protruding from the back side to the front side, and has an inner space on the back side. Each wire of the rear protective tool 31b is attached to the outer periphery of the lower end along the outer shape of the saddle 214 as shown in the figure. The size of each wire in the wire group can be set according to the size of the main body. Preferably, each wire rod is formed so that the width (width between both limbs) gradually widens toward the tip. The number of wire rods constituting the wire rod group can be appropriately set according to the size and application of the main body. As an example, the lower limit of the number of wires is, for example, one, preferably two, and the upper limit is, for example, eight, preferably six.

The rear protector 31b is located behind the saddle 214 of the main body 21 and acts as a shield to protect the driver and contacts. Since the rear protective tool 31b has a gap between the wires in the loop surface direction, here in the lateral direction, the balance is not lost or the rear protective tool 31b does not fall over even if a tail wind blows. Further, since there is a gap between the wires in the front-rear direction, the risk of falling does not increase even in the case of a crosswind. Further, the rear protective tool 31b has advantages such as light weight, easy cleaning, and easy manufacturing.

The rear protective tool 31b is formed in a convex shape, and in this order, the minimum wire rod 43b, the second large wire rod 42b, and the maximum wire rod 41b are elastically contacted with the contact object in this order according to the contact object, and the bicycle body and operation are performed. Reduce contact with the person, mitigate the impact and protect the driver and contact.

Two finger protectors 31c are included symmetrically, and are attached to the periphery of both the left and right grips 2112. As an example, the finger protector 31c is a group of inner and outer stacked convex wire rods in which two wire rods (41c, 42c) having substantially U-shaped or C-shaped loops of different sizes are arranged at predetermined intervals. ..

More specifically, in the finger protector 31c, the loops of the respective wire rods are arranged so as to be overlapped inside and outside in the loop surface direction, and the loop of the small wire rod 42c is included in the loop of the large wire rod 41c. Further, in the finger protector 31c, each wire rod is arranged back and forth in the direction orthogonal to the loop surface, the small wire rod 42c is arranged in the front, and the large wire rod 41c is arranged in the rear.

Both ends of each wire in the wire group are attached along the outer circumference of the central end of the grip 2112 so that both ends are located on the center side and the tip is located on the left (right) side. The finger protector 3c protrudes diagonally forward from both ends to the tip, is located in front of the grip 2112, is located in front of the brake lever, and surrounds the front of the finger.

As a result, the finger protector 31c is formed in a convex shape protruding from the back side to the front side, and has an inner space on the back side. The size of each wire and the number of wires in the wire group can be set according to the size of the main body or the grip. As an example, the lower limit of the number of wires is, for example, one, preferably two, and the upper limit is, for example, five, preferably four.

The finger protector 31c is located in front of the grip 2112 and acts as a shield to reduce contact objects or contact with the driver's fingers, reduce impact and protect the driver. In addition, the contact of the contact with the main body is reduced, the impact is mitigated, and the contact is protected. Further, the finger protector 31c has advantages such as light weight, easy cleaning, and easy manufacturing.

The finger protector 31c is formed in a convex shape and elastically contacts the contact object in this order in the order of the minimum wire rod 42c and the maximum wire rod 41c according to the contact object, reducing contact with the bicycle body and the driver. Protects the driver and contacts by mitigating impact.

As shown in FIG. 3, the front wheel upper protective device 31d is attached around the front wheel 216. As an example, the front wheel upper protective device 31d is formed by arranging three wire rods (41d, 42d, 43d) having substantially U-shaped or C-shaped loops of different sizes (41d, 42d, 43d) at predetermined intervals. Includes a group of wire rods.

More specifically, in the front wheel upper protective tool 31d, in the loop surface direction, the loops of the respective wire rods are arranged so as to be overlapped inside and outside, and the loop of the second large wire rod 42d is included in the loop of the maximum wire rod 41d, and the second large wire rod is included. The loop of the third large wire (minimum wire) 43d is arranged so as to be included in the loop of the wire 42d. Further, in the direction orthogonal to the loop plane, each wire rod is arranged vertically, the maximum wire rod 41d is arranged at the lowermost position, the minimum wire rod 43d is arranged at the uppermost position, and the second large wire rod 42d is arranged between them. As a result, the front wheel upper protective tool 31d is formed in a convex shape protruding from the back side to the front side, and has an inner space on the back side.

Each wire in the wire group of the front wheel upper protective tool 31d has a front end located at the front and both ends positioned at the rear, and both ends are attached to the front fork 213. In the illustrated example, each wire is attached above the crotch of the front fork 213 and below the upper end of the front fork 213. Each wire is curved forward and downward from both ends to the tip. In the present embodiment, the main body 21 does not have the front wheel mudguard, but when the main body 21 has the front wheel mudguard, the front wheel upper protective device 31d is arranged above the front wheel mudguard (front side).

The size of each wire in the wire group can be set according to the size of the main body. As an example, the maximum wire rod 41d has a length surrounding approximately 1/5 to 1/3 of the outer circumference of the front wheels (outer circumference of the tire), and has a width larger than the width of the front wheels (diameter of the tire). The number of wire rods constituting the wire rod group can be appropriately set according to the size and application of the main body. As an example, the lower limit of the number of wires is, for example, one, preferably two, and the upper limit is, for example, eight, preferably six.

The front wheel upper protective device 31d is arranged so as to surround the upper part of the front wheel 216, and protects the driver and the contact person by reducing contact with the front wheel 216 and mitigating the impact. The front wheel upper protective device 31d prevents a contact person or a contact object from getting caught in the front wheel. Since the front wheel upper protective tool 31d has a gap between the wires in the loop surface direction, the air resistance does not increase even if a headwind blows. Further, since there is a gap between the wires in the vertical direction, the risk of falling does not increase even in the case of a crosswind. Further, the front wheel upper protective device 31d has advantages such as light weight, easy cleaning, and easy manufacturing.

5 and 6 are diagrams for explaining an example of a wire rod group, more specifically, an example of an inner / outer overlapping type convex wire rod group. As shown in FIG. 5, when the massive contact object O hits the wire rod group, first, the smallest wire rod 43 located on the front side receives a load and bends. Next, the second large wire rod 42 on the back side thereof receives a load and bends. Next, the maximum wire rod 41 on the innermost side is loaded. As shown in the figures a, b, c, d, and e, the wires that receive the load gradually increase or are replaced. At that time, the tip 401 serves as a support portion that holds the object O and supports the load.

FIG. 6 describes an example of the flow from when the contact object O hits the wire rod group to when it separates from the wire rod group. (1) When the contact object O is close to the wire rod group but has not yet hit, the minimum wire rod 43 is on the front side closest to the contact object O and the maximum is on the back side farthest from the contact object O. The wire rod 41 has a second large wire rod 42 between them, and has a gap equal to or larger than the wire diameter (thickness) of the wire rod. Each wire has a substantially arcuate shape that is slightly convex on the front side in a lateral view.

(2) When the contact object O approaches the wire rod group and begins to hit the wire rod group, the contact object O first hits the limb of the minimum wire rod 43. Then, the minimum wire rod 43 bends to the back side and approaches the adjacent second large wire rod 42.

(3) When the full load of the contact object O is applied to the wire rod group, the minimum wire rod 43 further bends to the back side and the minimum wire rod 43 enters the inside of the loop of the second large wire rod 42. Then, the second large wire rod 42 also comes into contact with the contact object O and receives a load, and the second large wire rod 42 bends to the back side and approaches the adjacent maximum wire rod 41.

(4) The minimum wire rod 43 and the second large wire rod 42 further bend to the back side and enter the inside of the loop of the maximum wire rod 41. Then, the maximum wire rod 41 also comes into contact with the contact object O and receives a load.

On the other hand, the contact object O slides forward along the limb while receiving the elastic force of the wire rod. Then, the tip of the minimum wire rod 43 supports the contact object O.

(5) When the contact object O gets over the tip of the minimum wire rod 43, the tip of the second large wire rod 42 supports the contact object O, the minimum wire rod 43 is released from the load, and returns to the original state.

(6) When the contact object O gets over the tip of the second large wire rod 42, the tip of the maximum wire rod 41 supports the contact object O, and the second large wire rod 42 is released from the load.

(7) When the contact object O gets over the tip of the maximum wire rod 41, the maximum wire rod 41 is released from the load, and the contact object O separates from the wire rod group.

In this way, when the contact object O hits the inner / outer overlapping type convex wire rod group, the wire rod group supports the contact object O while elastically bending to alleviate the impact. When the contact object is plate-shaped, the minimum wire rod 43, the second large wire rod 42, and the maximum wire rod 41 come into contact in that order, so that contact with the main body and the driver is reduced and the impact is mitigated. To protect the driver.

Returning to FIG. 4, the rear wheel upper protective device 31e will be described. The rear wheel upper protective device 31e is attached around the rear wheel 217. As an example, the rear wheel upper protective device 31e is formed by arranging four wire rods (41e, 42e, 43e, 44e) having substantially U-shaped or C-shaped loops of different sizes (41e, 42e, 43e, 44e) at predetermined intervals. Includes a group of stacked convex wires.

More specifically, in the rear wheel upper protective tool 31e, in the loop surface direction, the loops of the respective wire rods are arranged so as to be overlapped inside and outside, and the loop of the second large wire rod 42e is included in the loop of the maximum wire rod 41e, and the second The loop of the third large wire rod 43e is included in the loop of the large wire rod 42e, and the loop of the fourth large wire rod (minimum wire rod 44e) is included in the loop of the third large wire rod 43e. Further, in the direction orthogonal to the loop plane, each wire rod is arranged vertically, the maximum wire rod 41e is arranged at the lowermost position, the minimum wire rod 44e is arranged at the uppermost position, and the second large wire rod 42e and the third large wire rod 43e are arranged between them. Will be done. As a result, the rear wheel upper protective tool 31e is configured in a convex shape protruding from the back side to the front side, and has an inner space on the back side.

Both ends of each wire rod in the rear wheel upper protective tool 31e are attached to the rear fork 218 so that both ends are located in the front and the tip is located in the rear. In the illustrated example, both ends of each wire are attached to each of the crotch of the rear fork 218 so as to straddle the crotch of the rear fork 218. Each wire is curved backward and downward from both ends to the tip. In the present embodiment, the main body 21 does not have the rear wheel mudguard, but when the main body 21 has the rear wheel mudguard, the rear wheel upper protective device 31e is arranged above the rear wheel mudguard.

The size of each wire in the wire group can be set according to the size of the main body. As an example, the maximum wire rod 41e has a length that covers approximately 1/5 to 1/3 of the outer circumference of the rear wheel (outer circumference of the tire), and has a width larger than the width of the rear wheel (diameter of the tire). Further, the number of wire rods constituting the wire rod group can be appropriately set according to the size and application of the main body. As an example, the lower limit of the number of wires is, for example, one, preferably two, and the upper limit is, for example, eight, preferably six.

Further, preferably, each wire rod of the front wheel side protective tool 31f is formed asymmetrically with respect to the center of the loop surface, and one end side is arranged on the front side by a high position and the other end is arranged on the back side by a low position. , Consists of curved surface.

The size of each wire in the wire group can be set according to the size of the main body. As an example, the maximum wire rod 41f has a size equal to or smaller than the outer circumference of the tire, for example, has the same size as the inner circumference of the tire, and the minimum wire rod 43f has a size equal to or larger than the outer circumference of the hub. Further, the number of wire rods constituting the wire rod group can be appropriately set according to the size and application of the main body. As an example, the lower limit of the number of wires is, for example, one, preferably two, and the upper limit is, for example, eight, preferably six.

The front wheel side protector 31f protects the driver by reducing contact with the front wheel 216 and mitigating the impact. Further, the front wheel side protective device 31f can prevent a contact person or a contact object from getting caught in the front wheel 216 or the spokes 2161. Since the front wheel side protective device 31f has a gap between the wires, it does not increase the air resistance and does not increase the risk of falling. Further, the front wheel side protective device 31f has advantages such as light weight, easy cleaning, and easy manufacturing.

The rear wheel side protective device 31 g is attached around the rear wheel 217. The rear wheel side protective device 31g may be provided on only one of the left and right sides, or may be provided on both sides. An example provided on the left side will be described below.

The rear wheel side protective device 31g is attached to the rear fork 218 so as to cover the side of the rear wheel 217, and is located on the front side of the pedal 219. In the illustrated example, both ends of each wire are attached to the front side of the left crotch of the rear fork 218 so that the tip is located forward and both ends are located rearward.

As a result, the rear wheel side protective device 31g is configured in a planar shape so as to cover the rear wheel 217 from the side. The size of each wire in the wire group can be set according to the size of the main body. The number of wire rods constituting the wire rod group can be appropriately set according to the size and application of the main body.
