Description

  The present invention relates to an auxiliary cushion that is used together with a child rider attached to an adult bicycle or the like and is attached to a grip member that is gripped by a child seated on the rider.

  A bicycle rider may be used to stably seat children (including infants) on bicycles for adults (including bicycles with electric auxiliary power and engine auxiliary power, tricycles, etc.).

  There is a type in which a passenger car, which is an auxiliary chair for an infant, is installed between a bicycle driving handle and a driver's seat (saddle). In this case, since there is a driving handle immediately before the child seated on the passenger car, a part of the child's body may accidentally contact the driving handle.

  Therefore, an auxiliary cushion is attached to the driving handle to prevent the child's body from coming into direct contact with the driving handle and protect the child. For example, there is one in which a handle is covered with an auxiliary cushion and held by a cloth fastener or the like (see Patent Documents 1, 2, and 3). In addition, there are some which protect a child by covering a child's grip provided integrally with the passenger in front of the child's seat with a cushion (see Patent Documents 4, 5, and 6).

  Conventionally, an air cushion is used (Patent Documents 1 and 3), or a cushioning material such as a sponge having flexibility is packed therein (Patent Documents 2 and 6). For this reason, there was a problem that the inside of an auxiliary cushion cannot be used as an article storage space.

  If a flexible article can be stored inside the auxiliary cushion, the entire auxiliary cushion must be removed from the bicycle's driving handle or a child's grip (hereinafter referred to as a gripping member) when putting in or out the article. Will have to. This is because the auxiliary cushion is usually wound around a gripping member or the like, so that the contents cannot be taken in and out from the bag of the auxiliary cushion in this state. For this reason, not only is the attachment / detachment of the auxiliary cushion troublesome, but there is also a problem that the cushion in a state where the contents are exposed does not function as a cushion.

  The present invention has been made in view of such circumstances, and the article stored therein can be easily put in and out while the auxiliary cushion is attached to a gripping member or the like, and functions as a cushion when the stored article is taken out. It is an object of the present invention to provide an auxiliary cushion for a bicycle child rider that is easy to use without causing any inconvenience.

  According to the present invention, an object of the present invention is to provide an auxiliary cushion for a bicycle child rider that is attached to a gripping member to be gripped by a child seated on a child rider attached to an adult bicycle. A bag body having a fastener that enables it, a flexible passenger cover made of a sheet that is folded and housed in the bag body, and a bag body that is provided on the lower surface of the bag body and placed on the grip member from above And a second holder that joins the front and rear ends of the bag body that is bent downward with the grip member interposed therebetween. Achieved by an auxiliary cushion for a bicycle child rider.

  A passenger-made cover made of a flexible sheet that is folded and stored in a bag body has appropriate flexibility and elasticity, so that the bag body that stores the cover covers sufficiently functions as a cushion. When the second holder is released, the bag body is held on the gripping member only by the first holder. At this time, since the bag body is substantially flat, the passenger cover placed therein can be easily taken out by opening the fastener of the bag body.

  In addition, the cushion with a medium content does not function as a cushion only by the bag body, but there is no inconvenience since a child is not riding when using the passenger compartment cover that is stored. At this time, the bag body is held by the grip member by the first holder. For this reason, it is not necessary to store the bag body in another place, and when the passenger cover is not used, it can be folded and easily stored in the bag body attached to the grip member. And if this bag body is folded and both ends are combined with the second holder under the gripping member, it can function as an auxiliary cushion. For this reason, the effect that it is easy to use is acquired.

  It is preferable that the first holder is detachably attached to the bag body with a snap button by passing the other end of the belt member, one end of which is fixed to the lower surface of the bag body, under the grip member near the center of the lower surface of the bag body. Since the band member can hold the bag body with the gripping member while the bag body is substantially flat, the passenger cover can be easily taken out of the bag body, and can be folded and put inside. . Since the snap button can hold the bag body firmly to the grip member, the bag body can be held here even when the passenger cover is taken out, and the bag body can be prevented from being lost.

  The second holder can be detachably coupled with the other end of the band member fixed to one of the front and rear ends of the bag body to the upper surface of the other end of the bag body with a cloth fastener (planar fastener).

  The passenger cover is preferably made of a flexible and elastic material, for example, a urethane resin sheet. The bag body has a substantially rectangular shape at the front and back, and an opening is provided on the front edge of the bag body to put in and out the inner passenger cover, and a fastener is attached to the opening. It becomes easier to take in and out.

  If another second auxiliary cushion is attached to the upper surface of the bag body, the cushion covers the grip member from above, and the effect of protecting the child is further improved. Further, even when there is no passenger cover inside, moderate shock absorption can be obtained, so that it can be used as a cushion. The second auxiliary cushion is made thick enough if the central portion is in close contact with the upper surface of the bag body except for the peripheral edge portion, and the peripheral edge is lifted away from the upper surface of the bag body. The buffering effect can be enhanced.

  When the center lower part of the grip member is vacant, the belt member may be passed through this vacant space as one. If there is a pipe or the like supporting the grip member near the center of the grip member, the band member may be bifurcated or divided into left and right so as to avoid interference with the pipe. A pair of left and right band members may be provided in order to firmly fix the bag body to the gripping member.

That is, the loading platform 40 is attached to the vehicle body frame 12 by coupling the front end thereof to the upper end of the seat pillar tube 28 and coupling the lower ends of a pair of left and right support rods 40a extending downward from the rear portion thereof to the backstay 34.

  Reference numeral 50 denotes a child rider, which is fixed on the loading platform 40. As shown in FIG. 1, the passenger car 50 includes a seating portion 52 that is long in the front-rear direction, a rear wall portion 54 that surrounds the rear portion of the seating portion 52 from the rear and right and left, and a front wall portion that stands up from the front edge of the seating portion 52. 56 and a pair of left and right footrests 58 extending downward from the front side edge of the seating portion 52.

  The passenger 50 has a frame made by combining and joining metal rods and is appropriately reinforced, and a metal mesh plate is fitted in the rear wall portion 54 and the front wall portion 56. A guard 60 is attached to the footrest 58 to prevent interference between the rear wheel 36 and the foot. A metal mesh plate is also fitted into the guard 60. A mat is laid on the seating portion 52, and the rear portion of the mat is bent along the inner rear surface of the rear wall portion 54 and stands upright.

  A gripping member 62 is integrally attached to the upper end of the front wall portion 56. That is, the metal rods 56a, 56a (see FIG. 3) which are the left and right edges of the front wall portion 56 protrude upward, are bent into a crank shape so as to approach each other, and are fixed to the horizontal linear gripping member 62. . Grips 64, 64 are attached to both ends of the gripping member 62 so that the child can hold it with their hands.

  Next, the auxiliary cushion 66 will be described. As shown in FIG. 3, the auxiliary cushion 66 has a rectangular shape that is long in the front-rear direction, and is attached to the central portion of the grip member 62 by being wound from above. In FIG. 3A, the arrow F indicates the front. The bag body 68 of the auxiliary cushion 66 is made of a flexible cloth, and the front edge thereof is an opening 70 (see FIG. 3C). The opening 70 can be opened and closed by a fastener 72. A folded passenger cover 74 can be stored in the bag body 68.
