Description

  [Technical Field] The present invention relates to a saddle cover for a bicycle, which is waterproof and hides scratches and dirt on the saddle, and by covering it, exhibits an appearance effect as if it was easily replaced with a new saddle. It relates to a thing that can be mounted on a large bicycle saddle.

In the recent bicycle market, saddles that are one or two times larger than conventional saddles are on the market. This is exactly the opposite of a sport-type slim and rigid saddle, which has a larger seating area and a more comfortable seating, or gives a higher-class feeling, and is requested by various consumers. It is a product created to satisfy.
FIGS. 5 to 7 show a saddle cover that can cover this large bicycle saddle. FIG. 5 is a perspective view of the saddle cover as viewed from above when attached to the large saddle, and FIG. 6 is a bottom view of the cover. is there.

The conventional saddle cover 50 is sewn from one piece of fabric 51, and a developed view of the fabric 51 is shown in FIG.
The fabric 51 has a size and a shape that can cover the upper surface portion, the peripheral side surface portion, and the peripheral edge portion of the lower surface portion of a substantially large bicycle saddle, and the material is also made of PVC (vinyl chloride), and is not very stretchable. It is not large, and its expansion rate is about 1.2 times or less, that is, about 120% or less.
Then, as shown in FIG. 7, the end portions of both sides 52 and 52 of the front end portion 51f of the cover covering the front end portion side of the saddle are sewn together so that the front end portion is formed in a cylindrical shape. The tip of the saddle can be covered.

A notch 53 is formed at the very center of the tip of the tip 51f. By the presence of this notch 53, the shape of the tip of the saddle can be better fitted and covered.
This notch 53 is indispensable for conforming to the saddle tip shape because the stretchability of the fabric 51 is not good. This is because, if this notch is not provided, the tip of the cover that covers the tip of the saddle will be sharp after sewing.
Thereafter, as can be seen from the bottom view of FIG. 6, the periphery of the lower surface opening 55 of the cover 50 is sewn in a circle together with the belt-like rubber 56 to complete the cover.
When sewing together with the belt-like rubber 56, sewing is performed so that the gathers are brought closer to the peripheral edge portion of the lower surface opening 55 of the fabric 51, and at the same time, the straps 57 and 57 are also sewn.

When the saddle cover 50 sewed as described above is covered with a large bicycle saddle, as shown in FIG. 5, the seam 58 of the sewn portions of the side edges 52, 52 of the tip 51f is the upper surface of the saddle. It appears on the club side.
In this conventional example, a belt-like rubber 56 is provided at the peripheral edge of the lower surface opening 55 of the cover. A string insertion part is formed at this peripheral part, and a tied string is inserted to form a fixing means. It is also possible.
In the above conventional example, a rubber band is used in order to obtain a simpler configuration.

Still another conventional example is the one described in Patent Document 1 previously proposed by the present inventor.
This saddle cover can easily get the appearance as if it was replaced with a new saddle by simply attaching the cover instead of replacing the saddle itself when the saddle itself is damaged or dirty. It is a simple saddle cover developed for the purpose.

And the place made into the structure uses the sheet-like body of the symmetrical substantially egg shape which is very rich in elasticity, gathers the peripheral part used as the lower surface opening part, and sews it with a belt-like rubber. Thus, a lower surface opening is formed, and an appropriate length of a portion corresponding to the front end portion of the belt-like rubber cover is sewn together.
Utility Model Registration No. 3131412

In the conventional example for the first large saddle, although the material of the fabric is PVC and the stretchability is low, it is possible to sew the sewing part at the tip of the cover covering the tip of the saddle. When the eye is attached to the saddle, it appears up to the upper surface (see FIG. 5).
This is because the material is extremely poor in stretchability, and there are problems in sewing.
As a result, there is a problem that rainwater or the like enters from the seam that appears on the upper surface of the saddle, but above all, it is extremely unsightly in appearance.

On the other hand, in the second conventional example, since the configuration is too simple, the belt-shaped rubber provided on the peripheral edge of the lower surface opening is weakened easily when it is attached to a large saddle, and tightening is performed. A serious defect occurs that becomes insufficient.
If the saddle was of normal size, there was no problem, but when it was installed on a large saddle, the simple configuration caused it to easily cause deterioration of the tightening of the bottom opening, which was a major drawback. It is.

Therefore, in the present invention, the conventional saddle cover is improved so that it can be appropriately mounted even on a large bicycle saddle, and when it is mounted, the seam on the tip side is the upper surface of the saddle. The first challenge is to provide something that does not appear in the department.
Furthermore, by improving the structure or configuration, it is possible to provide a material that can be easily mounted using a material having a higher elasticity, and to tighten and fix after mounting. It is also an issue of the present invention.

  In order to solve the above-mentioned problems, a first object of the present invention is a single sheet having a size and a shape that can cover at least the entire upper surface portion and peripheral side surface portion of a bicycle saddle and is waterproof. The sheet-like body is used, and both side edges on the tip side of the cover that covers the tip of the saddle in a plan view in which the sheet-like body is developed are sewn to each other by a predetermined length, and then the lower surface opening of the cover In a saddle cover in which a peripheral portion is sewed and an appropriate mounting and fixing means is provided at the peripheral portion of the lower surface opening, a sheet-like body rich in elasticity is used as the one sheet-like body, At least a pair of notches are formed on both side edges in a substantially symmetrical position in plan view, and the side edges facing each other are sewn together, and then the both side edges are sewn together. The tip of the cover Wear parts are attracted to the lower surface side of the saddle stitch of the sewing area is bicycle saddle cover, characterized in that so as not come on the top surface of the saddle.

  According to a second aspect of the present invention, in the first aspect of the present invention, an insertion portion is formed in the peripheral portion of the lower surface opening of the cover, and a string member or a stretchable string member is inserted into the insertion portion. A bicycle saddle cover characterized in that both ends are tightened so that the periphery of the opening can be drawn and fixed.

According to a third aspect of the present invention, in each of the above-mentioned inventions, one sheet-like body is composed of a joined sheet-like body of a polyurethane rubber on the front surface side and a polyester fabric on the back surface side. A bicycle saddle cover characterized in that the rate is about 150% or more.
Here, the elongation rate of “150%” means an elongation rate of about 1.5 times.

  In the first aspect of the present invention, at least a pair of left and right cutouts are formed at substantially right and left symmetrical positions in a plan view on both side edges on the front end side of a single sheet-like material having excellent stretchability. After the side edges facing each other are sewn together, the both side edges are sewn together so that the front end sewn part of the cover is drawn toward the lower surface of the saddle, and the sewn part Since the seam is configured so as not to appear on the upper surface of the saddle, its appearance is extremely smart, and it is possible to reduce the intrusion of rainwater and the like from the seam.

  In the second one of the present invention, an insertion part is formed in the peripheral part of the opening on the lower surface of the cover, and a string member or the like is inserted into the inside, and the two peripheral parts are tightened, and the peripheral part of the opening is drawn and fixed. In order to be able to do so, the attachment of the cover to the saddle is extremely robust and also extends the useful life of the attachment.

  In the third aspect of the present invention, regarding the configuration of the sheet-like body, the outer material is made of polyurethane rubber, and the inner surface side is made of a polyester fabric. Because the seam of the saddle is pulled toward the side and bottom of the saddle, its appearance is very smart and similar to that of synthetic leather. It can respond enough.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the accompanying drawings.
FIG. 1 is a development view of an embodiment of a saddle cover according to the present invention, and is an explanatory view showing a sewing procedure thereof.
This saddle cover is composed of a joined sheet-like body made of polyurethane rubber on the front surface side and polyester fabric on the back surface side thereof, and is stretchable with a very high expansion rate.
In this embodiment, the expansion ratio is about 1.75 times, that is, about 175%.

FIG. 1 illustrates the surface side of the sheet-like body 10, but the direction of the arrow F in the drawing is the forward direction and the front end side.
The development of the saddle cover according to the present invention is as shown in FIG. 1, but a pair of substantially V-shaped notches 14 and 14 are formed at appropriate portions of the side edges 12 and 12 on the tip side. ing. These notches 14 and 14 are provided symmetrically about the center line C. This notch 14 is a characteristic part of the present invention.

Moreover, compared with the conventional one, there is almost no cut at the center of the upper end of the developed view. This is because the sheet-like body of the present invention has an extremely high expansion / contraction rate, and therefore it is not necessary to provide a cut.
Hereinafter, the sewing procedure will be described.
First, in each of the notches 14, 14, the front side edge 14f and the rear side edge 14r are sewn together.

Next, the side edge portions 12, 12 on the front end side are pulled toward each other on the front side of the drawing, joined, and sewn. Two-dot chain lines 13 and 13 indicate the sewing direction.
As a result, the sewn lengths of the side edges 12 and 12 are significantly shorter than the conventional one.
Thereafter, the insertion portion for allowing the cord member to be inserted later is folded back by about 15 mm toward the front side (folded along the alternate long and short dash line 17 in the figure), and the elastic rubber cord member is disposed in the insertion portion. The lower surface opening of the cover is sewn in an annular shape in the direction of the arrow indicated by a two-dot chain line 18 in the figure.
A notch 19 is provided on the center line C on the rear end side of the sheet-like body 10. When this notch 19 completes the sewing of the lower surface opening, it becomes an opening for leading out the rubber string member, and both ends of the rubber string member are led out from the notch 19 to the outside.

FIG. 2 is a side view of the front end portion of the back surface of the cover according to the embodiment in which the sewing has been completed.
As can be seen from this figure, the front side edge 14f and the rear side edge 14r of the notch are first sewn together so that the seam 14s can be seen, and then the side edges 12, 12 on the front end side are visible. They are sewn together and the seam 12s can be seen.
Thus, in the present invention, the notch portion is provided and sewn, so that the front end portion of the cover is drawn to the lower surface side, and the seam 12s is combined with the expansion and contraction performance of the sheet-like body 10. It does not appear on the upper surface of the saddle.

FIG. 3 is a bottom view of the saddle cover according to the embodiment of the present invention. From this figure, the seam of the cover tip can be seen very well.
The sheet-like body 10 of the cover is sewn at the front end side to form a portion that covers the front end portion of the saddle, and the rear end side is sewn to form the lower surface opening 15.
The left and right cutouts 14 are sewn on the leading end side to form a stitch 14s, and both side edges 12 on the leading end side are sewn together to form a stitch 12s.

12a shows the front end of the seam 12s, and 12b shows the rear end of the seam 12s. Also in FIG. 2, 12a indicates the tip of the seam 12s.
Also in the seam 14s, 14a indicates the tip of the seam 14s, and 14b indicates the rear end of the seam 14s. Also in FIG. 2, 14a indicates the leading end of the stitch 14s, and 14b indicates the trailing end of the stitch 14s.

An insertion portion 16 is formed in the peripheral portion of the lower surface opening 15, a rubber string member 20 is inserted therein, and both end portions thereof are led out from a notch at the rear end, and are drawn and fixed by a stopper member 21. can do.
The stopper member 21 is configured such that the pressing portion 21p is always urged by an internal spring so that the inserted rubber string member 20 can be fixed. By pressing the pressing portion 21p, the fixing is released and the pressing member 21p is inserted. The rubber string member 20 can be drawn or loosened, and is similar to a generally known fastener.

FIG. 4 is a perspective view illustrating a state in which the saddle cover according to the embodiment is mounted on a large bicycle saddle.
As can be clearly seen from this figure, the stitches 12s on both side edges on the tip end side are located above the center of the tip of the saddle, and the end becomes the tip 12a of the stitch 12s. Further, the stitches 14s of the notch are located on both sides thereof, and the ends thereof become the tips 14a and 14a.

Thus, in the saddle cover according to the present invention, the seams 12s, 14s, and 14s appear on the peripheral side surface of the saddle, but do not come to the upper surface portion of the saddle.
Therefore, the appearance is extremely smart, and rainwater and the like can be prevented from entering from the upper surface.
This stitch state is clearly different from the conventional one shown in FIG.

As mentioned above, although one Embodiment of this invention was described, in this invention, the form can be changed as follows.
The sheet state according to the above embodiment uses a joined sheet-like body of polyurethane rubber on the front surface side and polyester fabric on the back surface side, but the elongation ratio is 150% or more, that is, about 1.5 times or more. The material can be freely selected. However, the surface side needs to have waterproof performance.
The string member inserted through the peripheral edge of the lower surface opening may be a string member that does not have elasticity.
Although the stopper member can also be freely selected as appropriate, it is also possible to simply tie and fix both ends of the string member without the stopper member.

Of course, the number of notches is not limited to a pair on the left and right, but two or more pairs may be provided, and the size of the notches can be set as necessary.
In short, it is only necessary that the opposite side edge portions of the notch portion are sewn together so that the sewing length between the side edge portions on the tip end side can be appropriately shortened. Therefore, the shape of the notch portion need not be substantially V-shaped.
As described above, the present invention has a very simple structure by selecting a material rich in stretchability and taking advantage of the characteristics of the material, and also improving the sewing structure of the tip part, but it has an extremely large effect. It is something that demonstrates.
