Description

Bicycle saddle with adjustable function {BICYCLE SADDLE HAVING FUNCTION OF SEAT POSITION ADJUSTMENT}

The present invention relates to a bicycle, and more particularly, to a bicycle saddle capable of adjusting the shape and width of a saddle part according to the type of use of the bicycle.

In general, a bicycle refers to a short-distance means of transportation propelled by turning wheels with the force generated by stepping on pedals by a rider with both feet. It is understood that the intended use is also included.

In general, such a bicycle is configured such that the power provided to the pedal is transmitted to the rear wheel and the front wheel passively rolls while being connected to the handle to determine the direction of travel. Such a bicycle is disclosed as Korean Patent Registration No. 10-1359816, and is disclosed in relation to the structure and saddle of the bicycle.

1 is a side view showing a general bicycle.

As shown in the prior art bicycle, a frame 1 on which a rear wheel 3 is supported for rotation, a handle 4 coupled to the front side of the frame 1 so as to be rotatable left and right, and a handle connected to the handle It is provided with a front wheel frame (6) for supporting the rolling by transmitting the steering force to the front wheel (2).

In addition, the frame is provided with a seat 5 so that the user can seat the buttocks, and the handle 4 is made in a form capable of gripping. In the illustrated details, the force of stepping on the pedal 50 is used as a power source, and a predetermined sprocket is rotated according to the operation of the pedal 50, and the sprocket rotated together with the rear wheel 3 is attached to a driving force transmission member such as a chain. By receiving rotational power, the rear wheel 3 finally rotates while moving forward. The user can drive by stepping on the pedal while seated on the seat with his buttocks and gripping the handle. The torque transmitted to the rear wheel provides upright and straight stability by the gyro effect.

Since the seat of such a bicycle has a smaller area than a general chair and needs to move both legs to turn the pedals, the front part is narrow in order to freely move the legs up and down, and the rear part is usually made wide to support the load of the human body.

However, the prior art bicycle seat applies continuous pressure and impact to the occupant's perineum, pelvic bones, anus, etc. during long-distance driving or high-speed driving, and when these phenomena accumulate, there is a problem of causing pain, and attempts have been made to improve this. .

The registered patent attempts buffering by configuring a cushion tube, and recently, in order to solve this problem, it is possible to distribute the pressure of the pelvic bones by configuring an adjusting device that divides the seats supporting the occupant's buttocks and separates them from each other. There is also a proposed technology, but there was a limit to properly relieving the shock applied during the operation of the bicycle.

It has been confirmed that the above-described pain is caused by continuous contact and friction with the bicycle saddle while the perineal region is particularly weak compared to other places, and measures to solve this problem are needed.

In particular, the prior art did not recognize that there is a difference between the part of the hip in contact with the saddle, the area, and the pressure in the situation where the waist is bent and the situation where the posture is upright and slow.

Accordingly, the present invention has been devised to solve the above problems, and an object of the present invention is to provide a bicycle saddle having an adjustment function capable of changing the shape by appropriately responding to the shape of the hip and the part of the applied pressure for each driving situation. .

The present invention, as a saddle mounted on a main frame of a bicycle, includes a front seat portion 1100 disposed to be movable back and forth on the front side, and a rear seat disposed on the rear side with respect to the front seat portion and separated to the left and right sides. Provided is a bicycle saddle having an adjustment function including a part 1200 and a deformable rail part 2100 that adjusts the separation distance between the rear seat parts while the width is varied according to the forward and backward movement of the front seat part.

However, the embodiments described below are only intended to be described in detail so that those skilled in the art can easily practice the invention, thereby limiting the scope of protection of the present invention. doesn't mean

In the following description, when a part is said to be 'connected' to another part, this includes not only the case where it is directly connected but also the case where it is connected with other parts or devices interposed therebetween. In addition, when a certain part 'includes' a certain component, this means that it may further include other components without excluding other components unless otherwise stated.

The present invention is basically a saddle mounted on a bicycle, and includes seat parts separated into front and rear left and right sides, and a transfer guide structure in which the seat parts can be moved forward and backward and left and right, but the front and rear movement of the seat part is provided. According to the present invention, a bicycle saddle having an adjusting function in which the distance between the left and right seat parts disposed at the rear is linked and changed is provided.

A bicycle generally includes a main frame for rotationally supporting the rear wheel, a steering shaft supported by the main frame to rotate left and right together with the front wheel, a handle connected to the steering shaft, and a saddle coupled to allow seating on the main frame. The basic structure of such a bicycle is as described above. Here, the bicycle may be formed in various shapes and is not necessarily limited to the examples of the drawings of the present invention. That is, it should be noted that the basic concept of the present invention can be applied to various types of deformable bicycles or various means of transportation in which people can ride and move. For example, a case where steering is performed on the front wheel or rear wheel as well as a transportation means equipped with a saddle of 2, 3, or 4 wheels should be understood as equivalent to the spirit of the present invention.

Figure 2 is a bottom view of a bicycle saddle having an adjustment function according to the basic concept of the present invention.

The front seat portion 1100 disposed on the front side and the rear seat portion 1200 disposed relatively rearward relative to the normal running direction of the bicycle are disposed so as to be spaced apart from and adjacent to each other in the front and rear directions. In addition, the rear seat portion 1200 is composed of two first seat members 1210 and second seat members 1220 that can be spaced apart from left to right, and the separation interval is variable according to the driving environment. it works The material of the seat portion may be made of various materials such as memory foam, sponge, synthetic rubber, and leather capable of buffering. In addition, the shape and size of the seat portion is not limited to the illustrated example and may be formed according to selection.

The front seat part 1100 basically moves forward and backward, and in conjunction with the movement of the front seat part 1100, the left and right intervals between the first seat member 1210 and the second seat member 1220 are varied, so that the overall saddle is comfortable. Its occupied area and spacing can be changed. The first sheet member 1210 and the second sheet member 1220 are linearly moved left and right to each other as a basic form of movement, but in the process of being spaced apart and adjacent to each other, the vertical position and / or the front and rear position and / or the human body The viewing angle may also be variable. This may be influenced by the shape of the guide frame 2200. In this regard, additional embodiments will be described later. In addition, although the movement of the front seat part 1100 is also based on linear movement in the front and rear directions, movement in the vertical direction or change in angle may be allowed.

A deformable rail portion 2100 is formed to support the forward and backward movement of the front seat portion 1100, and the deformable rail portion 2100 is disposed along the front and rear directions of the saddle as a whole. The front seat part 1100 is coupled to the deformable rail part 2100 in the adjustment bracket part 3000 coupled to the lower side, and the adjustment bracket part 3000 and the deformable rail part 2100 are coupled so that relative movement is possible. do. Accordingly, the deformable rail unit 2100 can perform a guide function for forward and backward transfer of the adjustment bracket unit 3000, but it is preferable that the basic transfer guide and support for the load be made in the area connected to the frame, which will be described later. do.

The present invention proposes a configuration in which the width of the deformable rail part 2100 can be changed left and right in order to link the movement and deformation of the rear seat part 1200 with the movement of the front seat part 1100. The first sheet member 1210 and the second sheet member 1220 constituting the rear seat portion 1200 may be moved together at the rear end of the deformable rail portion 2100 according to the deformation.

According to the above concept, the front seat part 1100 is coupled to the deformable rail part 2100 so as to be movable back and forth, and the first seat member 1210 and the second seat member 1220 are at least of the deformable rail part 2100. They will be coupled so that they can move together according to left and right transformation (or movement).

The adjusting bracket part 3000 moves along the deformable rail part 2100 and guides the forward and backward movement of the front seat part 1100, and at the same time supports the load of the front seat part 1100 upward, and the deformable rail part ( 2100), it also performs the function of adjusting the width according to the variation of the contact area. A preferred embodiment of the adjustment bracket unit 3000 will be described later.

The deformable rail part 2100 is slidably coupled to the guide frame 2200 so that both end sides can move left and right according to the width change from the rear side to the left and right. Referring to the drawings, the guide frame 2200 is disposed across the left and right directions from the rear side of the saddle, and the width adjustment follower 2130 formed at the rear end of the deformable rail unit 2100 is the guide frame 2200. It is connected in a form that roughly wraps the . When the width is changed by the movement of the adjusting bracket part 3000, it is moved to be spaced apart and adjacent to each other in response to this.

In the present invention, the movement direction of the forward and backward movement of the front seat portion 1100 is defined as the first direction (α), and the movement direction of the left and right movement of the rear seat portion 1200 is defined as the second directions (β1, β2). However, it should be noted that the movement does not necessarily mean only linear movement.

The width adjustment tracking unit 2130 may be moved upwardly according to deformation of the deformable rail unit 2100 by combining the first sheet member 1210 and the second sheet member 1220, respectively. A stopper part 2210 may be further disposed at an end of the guide frame 2200. In order to support the load of the first sheet member 1210 and the second sheet member 1220, support structures for the deformable rail unit 2100 or support structures for the support frame (4000 in FIG. 3) may be additionally adopted. Since various well-known configurations for support may be applied to this, a detailed description thereof will be omitted.

The guide frame 2200 can mainly perform a function of supporting the load of the rear seat portion, and a support frame is additionally coupled thereto. Examples related to this will be described below.

3 is a view showing the operation of a bicycle saddle having an adjustment function according to a preferred embodiment of the present invention.

In the illustrated details, it is viewed from the lower side, and the deformable rail unit 2100 is disposed on the lower side of the front seat unit 1100 along the front-back direction, and the first seat member 1210 is disposed on both rear sides of the front seat unit 1100. And the second sheet member 1220 is disposed.

The adjusting bracket part 3000 coupled to the front seat part 1100 is movable in the forward and backward directions of the deformable rail part 2100, and accordingly, when the width of the deformable rail part 2100 is changed, the width adjusting following part 2130 ) is moved in the width direction along the guide frame 2200 and the distance between the first sheet member 1210 and the second sheet member 1220 connected to the deformable rail unit 2100 is adjusted as described above.

The deformable rail unit 2100 has a shape that is narrower at the front side and wider toward the rear side, and is not necessarily limited to the illustrated shape if this concept is followed.

Referring to FIG. 2 , the front end side forms a connection portion 2101 in which branch portions on both sides are connected to each other, and elastic restoring force in a widening direction or a narrowing direction is operated around the connection portion 2101. To this end, it is preferable that the deformable rail part 2100 is made of a material capable of elastic deformation at least in the width direction and having restoring force.

As an example, the deformable rail unit 2100 can be divided into a front control unit 2110 with a relatively narrow left-right spacing and a rear control unit 2120 with a relatively wide left-right spacing. 3(a) shows that the adjusting bracket part 3000 is disposed in the area of the rear adjusting part 2120, and as the adjusting bracket part 3000 moves back and forth, deformation of a relatively small distance (angle) occurs. there is. In addition, (b) of FIG. 3 shows that the adjusting bracket part 3000 is disposed in the area of the front adjusting part 2110, and a relatively large distance (angle) is obtained according to the forward and backward movement of the adjusting bracket part 3000. Note that transformation occurs. To this end, a connection portion where a sudden change in angle or distance occurs may be disposed between the front control unit 2110 and the rear control unit 2120.

In addition, it is preferable that one or more protrusions protruding in the outer circumferential direction are disposed at one or more selected points of the deformable rail part 2100 in order to provide some degree of fixing force to the position according to the forward and backward movement of the adjustment bracket part 3000. Do. In the illustrated example, a pair of left and right front protrusions 2111 and rear protrusions 2121 are formed on the front and rear sides, and corresponding grooves or holes may be formed in the adjustment bracket part 3000. The protrusions may be made of a structure or material capable of being inserted or deformed with elastic restoring force in the inner circumferential direction.

As described above, the guide frame 2200 is disposed below the rear seat portion 1200 so that the width adjustment following portion 2130 can function as a guide sliding left and right along the guide frame 2200 . In the illustrated example, the guide frame 2200 is shown in a substantially convex shape downward. In this case, as the first sheet member 1210 and the second sheet member 1220 move in the direction in which they are spaced apart, they look toward the center in the width direction. the slope will be greater. Note that the angle according to the positional movement of the rear seat portion 1200 may also be varied according to the shape of the guide frame 2200.

A stopper part 2210 may be coupled to an end of the guide frame 2200, and a horizontal movement limit of the width adjusting follower 2130 may be set according to the arrangement of the stopper part 2210. This stopper performs a function to prevent the first sheet member 1210 and the second sheet member 1220 from being separated from the predetermined path due to impact or excessive deformation, and thus safety will be improved.

On the other hand, the guide frame 2200 can perform a function of supporting the entire structure, particularly the rear seat portion, to which the support frame 4000 is connected to the front. The adjustment bracket unit 3000 is basically moved along the deformable rail unit 2100, but in order to firmly support the load, it is preferable that the transfer is mainly guided along the support frame 4000. That is, the support of the transport guide and the load for the front seat portion 1100 is performed by the support frame 4000, and the deformation rail portion 2100 performs the change in width according to the transport, thereby distinguishing the functions of the operation. Reliability, durability and safety can be guaranteed.

To this end, preferably, the upper side of the adjustment bracket unit 3000 is an adjustment unit 3100 connected to the deformable rail unit 2100 and the lower side is a transfer unit 3200 connected to the support frame 4000. They may be combined with each other or composed of one member to perform different functions. Examples related to this will be described later.

As described above, according to the structural separation of deformation and load support, the support frame 4000 supports the load of the front seat portion 1100 on the upper side as a whole, and the main frame of the bicycle (see 1 in FIG. 1) on the lower side. It can be fastened with the mountable part 4100 that can be connected. The mounting portion 4100 may have a known structure and shape, such as a fastening bracket capable of fixing a post inserted into an insertion hole formed in a main frame.

The support frame 4000 may be combined with the guide frame 2200 at the rear end side, and unlike the width control follower 2130, it would be preferable to fasten so that mutual flow does not occur in the left and right directions. In the illustrated embodiment, the attachment part 4030, which is the rear end of the support frame 4000, is disposed inside the width adjustment following part 2130 so as not to obstruct the deformation operation of the deformable rail part 2100. In some cases, Of course, the arrangement may be substituted. Additionally, a fastening means (reference numeral not shown) may be added to the attachment part 4030 so as to be fastened by adjusting the position. In some cases, it may be considered that the attachment part 4030 is coupled to the guide frame 2200 by welding.

As described above, the support frame 4000 is disposed on the lower side of the deformable rail unit 2100 to guide forward and backward movement together, support a load, and combine with the main frame. To this end, it is preferable that the shape of the support frame 4000 is separated from a predetermined area so that it can perform a function as a structural frame and a guide function. A movable part 4010 for guiding movement, a bent part 4020 bent downward at the rear end of the movable part 4010 to which the mounting part 4100 is fastened, and a guide frame 2200 at the rear end of the bent part 4020 It consists of an attachment part 4030 coupled to. Unlike the deformable rail unit 2100, the movable part 4010 may preferably be formed in a parallel form on both sides so as to be faithful to the function of accurately supporting only forward and backward transfer.

According to this embodiment, (a) of FIG. 3 shows that the adjustment bracket part 3000 is disposed on the rear side of the movable part 4010. Note that according to the arrangement and shape of the bent part 4020 described above, the front end of the bent part 4020 may also function as a kind of stopper that defines a limit position at which the adjustment bracket part 3000 can move backward. In this case, the front seat portion 1100 and the rear seat portion 1200 are most adjacent, and similarly, the first sheet member 1210 and the second sheet member 1220 are also adjacent.

(b) of FIG. 3 shows that the front seat part 1100 is moved forward and the adjustment bracket part 3000 is disposed on the front side of the front adjusting part 2110 and the movable part 4010 of the deformable rail part 2100. indicates Accordingly, the deformable rail unit 2100 is deformed in a wide-open form, and the width control follower 2130 at the rear end is disposed in the most spaced form. Accordingly, the first sheet member 1210 and the second sheet member 1220 connected to the upper side of the deformable rail unit 2100 are spaced apart from each other on both sides.

Figure 4 is a perspective view showing a bicycle saddle having an adjustment function of the present invention described above from above.

Referring to FIG. 3, (a) of FIG. 4 shows a state in which the front seat portion 1100 and the rear seat portion 1200 are most adjacent. Accordingly, in the guide frame 2200, the width adjusting tracking units 2130 on both sides are disposed most adjacent to each other, and the first sheet member 1210 and the second sheet member 1220 connected to the upper side are also disposed adjacent to or in close contact with each other. do. This is suitable for daily driving or driving in congested areas or slow-moving situations where visibility is required. Note that the shape of the upper side of the front seat portion 1100 and the rear seat portion 1200 will be able to apply various known shapes and is not necessarily limited to the illustrated example. In this state, the front and back space 1310 is minimized, and depending on the design, the front seat 1100, the first seat member 1210, and the second seat member 1220 may be set to come into close contact with each other.

(b) of FIG. 4 shows a state in which the width adjusting following part 2130 on the rear side is spaced apart while the adjusting bracket part 3000 moves forward, and thus the front coupled to the upper side of the adjusting bracket part 3000. The seat portion 1100 is moved forward, and the first sheet member 1210 and the second sheet member 1220 are spread left and right. By this operation, the front and rear separation space 1310 and the left and right separation space 1320 are in a maximum state.

For example, when it is necessary to secure a field of vision or to improve fine maneuverability, it would be appropriate to sit in a seated state with the waist stretched and drive in a contracted state as shown in FIG. 4(a). Here, when the waist is bent during high-speed driving, there is a change in the friction part with the perineum and the contact area of the buttocks and thighs tends to widen somewhat, so the gap is widened in the front and rear and left and right as shown in FIG. It would be appropriate to form

Additionally, a space for perineum may be provided by extending forward from the rear side of the front seat portion 1100, which may be formed in the form of a groove or hole of a selected shape. In addition, it is preferable that grooves or holes concave outwardly are formed in the front facing portions of the first sheet member 1210 and the second sheet member 1220 in consideration of the space for the perineum. Even when the front and back space 1310 and the left and right space 1320 are minimized, the perineum space is provided to ensure comfort in any driving situation.

5 is a view showing a deformable rail unit and a guide frame separated according to an embodiment of the present invention.

The deformable rail part 2100 is basically formed in a form in which the distance between the two branches gradually widens as it goes to the rear side starting from the connection part 2101 on the front side. The adjusting bracket unit 3000 can change this distance by resisting the elastic restoring force on both sides of the branch. When the interval between the deformable rail units 2100 increases linearly, the width, more precisely, the interval between the width adjustment tracking units 2130 will be constantly changed according to the forward and backward movement of the adjustment bracket unit 3000.

The change in width according to the forward and backward movement may depend on the shape of the deformable rail unit 2100, and this embodiment will look at this in more detail.

The deformable rail part 2100 can be divided into a front adjusting part 2110 on the front side and a rear adjusting part 2120 on the rear side relative to the front adjusting part 2110, and the front adjusting part 2110 And it may be made of a curved portion 2112 connecting the rear adjusting portion (2120). The front control unit 2110 is a portion that starts from the connection unit 2101 and extends to both sides and the rear side, and may have a relatively narrower width than the rear control unit 2120. The inflection part 2112 is an element that rapidly changes the width of the front adjusting part 2110 and the rear adjusting part 2120, but the curvature can be adjusted for the movement guide of the adjusting bracket part 3000. .

A front protrusion 2111 and a rear protrusion 2121 may be formed outside the front adjusting unit 2110 and/or the rear adjusting unit 2120 to position and fix the adjusting bracket unit 3000 . However, the number and arrangement of the protrusions are optional.

In the illustrated embodiment, the guide frame 2200 is expressed in a straight line form when viewed from above. As another embodiment, a case of being concave forward may be considered. In this case, the front and rear positions may be varied according to left and right movement, and the arrangement of the rear seat portion 1200 may depend on the shape of the guide frame 2200. In this regard, additional embodiments will be described later.

6 is a view showing a state in which a bicycle saddle having an adjustment function according to an additional embodiment of the present invention is viewed from the rear side.

As described above, the left-right position of the rear seat part 1200 basically depends on the shape of the deformable rail part 2100 by the adjusting bracket part 3000. That is, because the first sheet member 1210 and the second sheet member 1220 are coupled to the width adjusting follower 2130 and move left and right together, the vertical and forward movement and angle are the shape of the guide frame 2200. can depend on

In an additional embodiment of the present invention, a method to further diversify the position and shape according to the left and right spacing of the rear seat portion 1200 is proposed.

In the example of FIG. 3, since the guide frame 2200 is convex downward, the first sheet member 1210 and the second sheet member 1220 have a predetermined inclination angle so as to look at the center of a virtual arc when moving in the left and right directions. will form regularly.

As described above, the first sheet member 1210 and the second sheet member 1220 are coupled to the upper side of the width adjusting follower 2130 directly or with a connecting member interposed therebetween. In addition, the attachment part 4030 between the width adjusting following part 2130 of the guide frame 2200 couples the support frame 4000 and the guide frame 2200 as described above.

In the illustrated example, the guide frame 2200 has a substantially horizontal straight line shape in the center section 2220 adjacent to the center in the width direction. Accordingly, when the width adjusting follower 2130 moves the central section 2220, only the width of the left and right spaced spaces 1320 will change.

On both sides of the central section 2220, a variable section 2230 is formed that slopes gradually to rise, and as it moves in the second direction β, the first sheet member 1210 and the second sheet member 1220 are separated from each other. As it does, it rises symmetrically to a predetermined height with an angle facing the center. As in the above-described embodiment, when the speed increases and the posture is lowered, the width of supporting the hips and thighs widens, and the left and right spaced space 1320, which is the central space, is opened while the rear seat portion 1200 moves slightly to the side while looking at the side It has an inclination toward the center so that it can be held well, and at the same time, the height of the rear side is increased so that the posture of lying down is made more smoothly.

The end side of the variable section 2230 is defined as an end portion 2240, and a stopper portion 2210 is disposed to determine a limit at a distance between the first sheet member 1210 and the second sheet member 1220. In the illustrated example, the variable section 2230 has a gentle slope at the distal end 2240 side.

The arrangement and position of the rear seat part 1200 moving in conjunction with the front seat part 1100 may be determined by the shape of the guide frame 2200, and in some cases, it may be considered that it is lowered according to the separation, Various forms can be applied if the concept of the present invention is applied.

7 is a view for explaining the adjusting bracket according to an embodiment of the present invention.

As described above, the adjusting bracket part 3000 performs the function of supporting the front seat part 1100 upwardly, while being supported by the support frame 4000 downwardly and guiding forward-backward transfer, the deformable rail part ( 2100) simultaneously performs the function of adjusting the distance while being transferred forward and backward.

If the spirit of the present invention is followed, the adjustment bracket unit 3000 may be applied in various configurations and shapes.
