Description

  The embodiment of the present invention relates to a bicycle gate installed in a park or the like, and more particularly, to a bicycle gate that allows a bicycle with a child seat to pass easily.

  At the entrance of public lands such as parks, plazas, stations and public facilities, or at entrances of private lands, gates with a plurality of poles are often installed in order to regulate the entry of motorcycles. This type of gate blocks the passage of motorcycles, but often has a frontage so that bicycles can pass.

The background of the increase in the installation of such gates (hereinafter referred to as bicycle gates) is as follows.
In recent years, with the spread of easy-to-ride motorcycles and scooters, illegal parking of motorcycles on the side of city roads has increased, and if left unchecked, it will be an obstacle to pedestrians' traffic and it is dangerous in various places. Had become.

Therefore, the Road Traffic Law was revised in June 2006 to strengthen regulations on illegal parking of motorcycles on roads. Due to the revision of the Road Traffic Law, illegal parking of motorcycles and the like on the road has been reduced, but an unexpected situation has arisen in which places not regulated by the Road Traffic Law are used for parking motorcycles. A typical example is illegal parking in a park. According to the Road Traffic Law, parking in places other than roads cannot be regulated, so that illegal parking in parks and the like cannot be controlled.
Under such circumstances, a bicycle gate installed at an entrance of a park or the like has emerged as a countermeasure against the hardship against illegal parking of a motorcycle or the like.

This type of bicycle gate is primarily intended to prevent the entry of motorcycles. On the other hand, it is also important not to hinder nearby residents from using the park.
In consideration of the fact that many park users usually use bicycles, conventional bicycle gates are designed so that motorcycles cannot be passed through while bicycles can pass. As a prior art relating to this type of bicycle gate, for example, there is one described in Patent Document 1.

JP 2009-13760 A

  In recent years, bicycles with a small tire diameter equipped with a child seat have become popular mainly among young mothers. In this type of bicycle (hereinafter referred to as a child-riding bicycle), the number of power-assisted bicycles is increasing, supported by higher performance of batteries.

  In a child riding bicycle, child seats are attached to the front and rear, respectively, and the width of the child seat is wide.

  Also, since it can carry two children, the loading weight can be close to 100 kg, the frame of the bicycle etc. is made robust, and the stand attached to the rear to stand the bicycle can be made sturdy Is characteristic. Such child-riding bicycles are often used by mothers to carry their children and take them to the park.

  However, in a conventional bicycle gate, when trying to pass a bicycle with a child on it, the child seat often hits the bicycle gate and cannot pass, and complaints have been received in various places. In addition, if the position of the entry blocking member is changed in order to dodge the child seat, it cannot hit the stand and cannot pass. Further, if the length of the barrier is shortened and the frontage is widened, the motorcycle passes.

  Therefore, an object of the present invention is to provide a bicycle gate that solves the above-mentioned problems of the related art and that can surely prevent the entry of a motorcycle and allow a child-riding bicycle or the like to pass with confidence.

In order to achieve the above object, a bicycle gate according to the present invention is a bicycle gate that is installed at an entrance of a public land or a private land to regulate the entry of a motorcycle and allow a bicycle to pass therethrough. A pair of struts erected at the entrance at intervals of, and an entry blocking member attached to each of the posts, wherein the entry blocking member is located at a position lower than the lowermost portion of the child seat mounted on the bicycle. And the distal end of the entry blocking member has an interval through which the bicycle can pass.

1 is a perspective view illustrating a bicycle gate according to a first embodiment of the present invention. It is a front view of the same bicycle gate. It is a side view which shows a child riding bicycle. It is a figure which shows the positional relationship of the approach prevention member and a stand when a child carries a bicycle through a bicycle gate. It is a figure which shows the positional relationship of an entrance prevention member and a stand when a child carrying bicycle passes from the position turned by one side. It is sectional drawing which shows the modification of the approach prevention part of the bicycle gate by 1st Embodiment. It is a perspective view showing a bicycle gate by a 2nd embodiment of the present invention. It is a front view of the same bicycle gate.

Hereinafter, embodiments of a bicycle gate according to the present invention will be described with reference to the accompanying drawings.
(1st Embodiment)
FIG. 1 is a perspective view illustrating a bicycle gate according to a first embodiment of the present invention. FIG. 2 is a front view of the bicycle gate.
The bicycle gate has a pair of columns 10, 10 and entry blocking portions 12, 12 attached to each column.
A metal pipe is used for the column 10 and is fixed to a concrete base. A cap 14 is attached to the upper end of the column 10 and closed.

  In the case of this embodiment, a metal semi-cylindrical or semi-cylindrical member is used as the entry preventing member 12. Therefore, a convexly curved surface portion 12 a is formed on the outer surface of the entry preventing member 12. As shown in FIG. 1, the entry preventing member 12 is attached to the support 10 via a bracket 15 in a horizontal posture at right angles. In that case, the entry preventing member 12 is attached such that the convex curved surface portion 12a faces downward.

In such a bicycle gate, the dimensions of each part in FIG. 2 are defined as follows.
W indicates an interval between the columns 10. Wa indicates the distance between the tips of the left and right entry blocking members 12. H1 is the height of the upper surface of the height of the mounting position of the entry blocking member 12. H2 is the height of the lowermost part of the convex curved surface portion 12a.

  In the case of the bicycle gate according to the present embodiment, the purpose is primarily to prevent the entry of the motorcycle, but it is possible to safely pass the child riding bicycle as shown in FIG. 3 without any problem. From this viewpoint, the dimensions of W, Wa, H1, and H2 are set as described later.

  3, reference numeral 20 denotes a front wheel, 21 denotes a rear wheel, 22 denotes a down tube, 23 denotes a saddle, 24 denotes a handle, and 25 denotes a carrier. The child seat includes a front child seat 26 attached to the handle 24 and a rear child seat 27 attached to the carrier 25.

  In the case of bicycles with children, there are many electric assist type bicycles so that two children can easily run. In the child riding bicycle shown in FIG. 3, the battery 28 for electric assist is also mounted, and an assist motor (not shown) is driven.

  In addition, in the case of a child riding bicycle, it is necessary to stand the bicycle in a stable state when putting the child on the front child seat 26 and the rear child seat 27 or dropping the child. For this reason, the stand 30 provided on the rear wheel 21 side is made rugged so as to protrude largely sideways as compared with a general bicycle.

Here, FIG. 4 is a diagram showing a positional relationship between the stand 30 and the entry preventing member 12 when the child-riding bicycle passes through the bicycle gate. In FIG. 4, the child-riding bicycle is assumed to be a mainstream bicycle having a wheel size of 20 inches.
As shown in FIG. 4, at least the width Was of the stand 30 is required for the interval Wa between the distal ends of the left and right entry blocking members 12. In this embodiment, the interval Wa is set slightly wider in consideration of a margin in the width Ws of the stand 30. The entry preventing member 12 is attached to the column 10 so as to be lower than the lowermost portions of the front child seat 26 and the rear child seat 27 mounted on the child riding bicycle as shown in FIG. In addition, the height H of the upper edge portion 30a protruding from the left and right sides of the free stand 30 suspended by a spring (not shown) is lower than the height H1 of the upper surface portion of the entry preventing member 12. The height H1 of the upper surface is set in this manner.

The bicycle gate according to the present embodiment is configured as described above. Next, the operation and effects will be described.
FIG. 4 shows a situation where the child riding bicycle is located exactly at the center of the bicycle gate. In this case, the center line 40 may be displayed on the road surface of the passage as guidance for passing through the gate.

  In FIG. 4, when the child riding bicycle is moved straight in this state, the bicycle can pass through the bicycle gate without any problem. Since the front child seat 26 and the rear child seat 27 are located above the entry blocking member 12, the entry blocking member 12 does not interfere. The problem is the stand 30 having the largest lateral width. However, since the space Wa between the entry blocking members 12 is larger than the width Ws of the stand 30, the entry blocking members 12 do not interfere with each other.

  Next, FIG. 5 shows a case where the child-riding bicycle passes at a position deviated to one of the left and right columns 10 and 10 or a case where the bicycle enters the gate obliquely. In this case, the end upper edge 30a of the one stand 30 comes into contact with the one entry blocking member 12.

  However, in this embodiment, since the surface which the stand 30 hits is the convex curved surface portion 12a, the stand 30 only slides on the convex curved surface portion 12a as the child riding bicycle moves forward. It can pass through the blocking member 12 without any problem.

  Specifically, the stand 30 is pushed down against the elastic force of a spring (not shown) lifting the stand 30 in the process of sliding along the convex curved surface portion 12a, and gets over the convex curved surface portion 12a. . Since the stand 30 slides smoothly on the convex curved surface portion 12a, there is no impact, and it is safe even if a child rides on the child seat.

  The above is a case where the child riding bicycle passes through the bicycle gate. However, in the case of a normal bicycle, since there is no portion where the entry blocking member 12 interferes, it is possible to pass without problems as long as the bicycle is passed in a normal manner. it can.

Next, a case where a motorcycle such as a motorcycle or a scooter passes through a bicycle gate will be described.
As described above, in the case of the bicycle gate of the present embodiment, the position of the entry blocking member 12 is set based on the fact that the stand 30 of the child riding bicycle can pass.
There are various types of motorcycles depending on the type and displacement, but motorcycles that need to be regulated by the bicycle gate of the present embodiment are 50cc scooter type motorcycles and 50cc small motorcycles (mainly Super Cub (Honda) This is a 125cc scooter. Since it is obvious that a motorcycle larger than this cannot pass through the automobile gate, the examination is omitted.

As in the bicycle gate according to the present embodiment, when the distance Wa between the entry blocking members 12 is adjusted to the width Ws of the stand 30 of the bicycle carrying a child, the front wheel and the cowl can pass through the bicycle gate in a 50 cc scooter type motorcycle. It was found that the muffler or the air cleaner on the rear wheel side could not pass through the approach-preventing member 12 because of the impingement.
Also, in the case of a 50 cc super cub type small motorcycle, although the front wheels passed, the cowl hit the entry blocking member 12 and could not pass.
In the case of a 125cc scooter, although the cowl barely passed, a part of the vehicle body hit the entry blocking member 12 on the way and could not pass.
Some 50cc motorcycles without a cowl could barely pass through the bicycle gate, but if they were barely, they would not seem to be able to pass through, so don't dare try to enter. It is normal, and it can be evaluated that the approach effect is sufficient for this kind of motorcycle.

Next, FIG. 6 is a diagram illustrating a modification of the entry blocking member according to the first embodiment.
The modification shown in FIG. 6A is an entry blocking member 50 having a semi-cylindrical cross section. The lower surface is a convex curved surface portion 50a. The modification shown in FIG. 6B is an entry blocking portion 51 having a circular cross section, that is, a cylindrical shape. The modification shown in FIG. 6C is an entry blocking member 52 having a semicircular cross section.

  Each of the above is an example having a downwardly curved surface, but the entry preventing member is not limited to a curved surface.

  The modification shown in FIG. 6D is an entry blocking member 53 having a cross section forming an isosceles triangle. In this case, the approach direction to the bicycle gate is the direction of the arrow. The modification shown in FIG. 6E is an approach blocking portion 54 whose cross section is a right-angled triangle.

  As in these modified examples, the entry preventing member does not necessarily have to be a curved surface as long as it is an inclined surface that continuously decreases in the entry direction.

(2nd Embodiment)
Next, a bicycle gate according to a second embodiment of the present invention will be described with reference to FIGS.
FIG. 7 is a perspective view showing a bicycle gate according to the second embodiment. FIG. 8 is a view of the bicycle gate as viewed from the front. 7 and 8, the same components as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals, and detailed description thereof will be omitted.

The second embodiment is an embodiment in which the following entry prevention assisting member 60 is added to the bicycle gate according to the first embodiment.
The approach-prevention assisting member 60 mainly aims at restricting a motorcycle in which the approach cannot be completely prevented by the approach-preventing member 12. As mentioned in the first embodiment, the motorcycle to be restricted may be a moped motorcycle without a cowl of 50 cc as an example.

  In this embodiment, attention is paid to the step on which the driver puts his or her feet during running as the part protruding left and right from the body of the small motorcycle, and the approach prevention assisting member 60 regulates this step. Therefore, the length, width, and interval of the entry prevention assisting member 60 are set such that a step is applied when the small motorcycle attempts to pass.

  According to the above-described second embodiment, the bicycle gate according to the second embodiment can reliably prevent entry of a small motorcycle without a cowl that leaks from regulation, for example.

  In the above-described second embodiment, the entry prevention holding member 60 has a rectangular plate shape, but is not limited thereto.
