Abstract

(57) [Summary] [Purpose] The protective frame attached to the tip of the armrest rod is made of a flexible material so that it can be easily folded in conjunction with the folding of the stroller. [Structure] Both ends are grips made of hard synthetic resin, and a protective frame body made of a flexible material is integrally formed between the two grips so that the grips can be used for infants. A through hole for inserting a fingertip is formed. [Effect] Since the protective frame is made of a flexible material, the folding operation can be easily performed in conjunction with the folding of the stroller.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protective frame that is attached to the tip of a stroller armrest rod, and particularly to a protective frame that is applied to a stroller having a structure that can be folded and carried.

[0002]

[Prior art]

 Strollers for use by infants of a relatively young age are constructed so that a protective frame is attached across the ends of armrest rods formed on both sides of the seat to prevent the infant from falling from the seat. Is common.

[0003] It is also known that the protective frame extended to the tip of the armrest rod is configured to be folded together with the stroller body when the stroller is folded small for carrying, and the structure for folding the protective frame is also known. Is known from the description of Japanese Utility Model Publication No. 62-72868.

[0004]

[Problems to be solved by the device]

 However, the folding structure of the protective frame, which is known from the description in the above publications, has a structure in which two hinge mechanisms are provided at positions that divide the protective frame formed in a planar U shape into approximately three equal parts, and the folding operation of the stroller is performed. In conjunction with this, the protective frame was also configured to be folded in a U-shape from the above hinge portion, which made the structure of the entire protective frame complicated and increased manufacturing costs.

In addition, since the protection frame having the conventional structure is formed of a rod or a rod having the same size as the entire protection frame, even if an infant tries to hold it, the palm size is too small to hold it accurately. There was also a drawback.

[0006]

[The purpose of the device]

 The present invention is intended to address the above-mentioned problems, and a stroller protection frame that is excellent in folding operability and that can be obtained at low cost by configuring the entire protection frame with a flexible material is provided. It is intended to be provided.

Another object of the present invention is to provide a protective frame for a baby car which has an extremely excellent usability by making the structure of the protective frame easy for an infant to grasp, and by making the surface of the grasping portion less slippery. It is what

[0008]

[Key points of the device]

 In the present invention, both ends are formed as a grip part formed of a hard synthetic resin, and a protective frame body formed of a flexible material is integrally formed in the middle of the two grip parts. The gist of the invention is a protective frame for a stroller in which a through hole for inserting a fingertip of an infant is formed in the grip portion.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

The stroller indicated by the symbol A is known as a portable foldable stroller, and has a pair of front leg rods 1 and 1 and a pair of rear leg rods 2 and 2 which are combined in an eight-shape. The armrest rods 3 and 3 are pivotally attached to the tip ends thereof, respectively, and the U-shaped push rod 4 having folding mechanisms 41 and 41 formed on the upper ends thereof is pivotally attached to the intermediate portions of the rear leg rods 2 and 2. Then, the base ends of the armrest rods 3, 3 are pivoted to a position slightly above the base end of the hand push rod 4, and the front end rods 1, 1 facing each other and the rear leg rods 2, 2 facing each other have a joint between them. The structure is such that both ends of the connecting rods 11 and 21 that can be folded into a letter shape are attached, and the seat-like floor 22 is surrounded by the push rod 4 and the front leg rods 1, 1 and the rear leg rods 2, 2. Also, the backrest portion 42 is continuously stretched.

In the stroller A described above, the lock mechanisms a, a attached to the upper ends of the rear leg rods 2, 2 are released, and the front leg rod 1 and the rear leg rod 2 are brought closer to each other to make the stroller flat in the front-back direction. By folding and further folding the push rod 4 and the connecting rods 11 and 21, it is possible to fold it into a planar U-shape as shown in FIG.

The protective frame 5 has its both ends detachably attached to the tips of the armrest rods 3 and 3 facing each other, and has both ends as gripping portions 5a and 5a, and has flexibility in the middle thereof. The protective frame main body 5b is interposed and integrated.

The grips 5a, 5a are made of a hard synthetic resin or the like, and a base end of a rod-shaped body having a length suitable for gripping by an infant sitting on a seat is placed on the tip of the armrest rod 3. A through hole 52 for inserting a finger is formed horizontally in the remaining portion.

Reference numeral 53 denotes a thin partition wall formed in an intermediate portion of the through hole 52, and the five fingers of the infant to be inserted into the through hole 52 are separated and inserted into the middle finger and the ring finger at the intermediate portion to improve gripping efficiency. Is configured.

Forming the partition wall 53 in the through hole 52 is not essential to the present invention.

Reference numeral 54 denotes a non-slip structure portion formed on the grip portion 5a, and a synthetic resin thin plate having a roughened surface is attached to the grip surface of the grip portion 5a, or the synthetic resin surface forming the grip portion 5a is attached. It is configured to have a matte finish by etching or other means to impede lubricity.

The protective frame main body 5b is made of a similar material such as rubber, soft synthetic resin or other flexible material. A thick core plate 56 is inserted, and the outer cover 55 and both ends of the core plate 56 are fixed to the grip portions 5a, 5a by locking pins 6, 6.

In the figure, reference numeral 57 denotes a thin metal plate for retaining the shape of the core plate 56. When the core plate 56 is molded, it is interposed in a molding frame to integrate the two, and the metal plate is The use of thin plate 57 is not essential for forming core plate 56.

[0019]

[Effect of device]

 As described above, the present invention has a structure in which the flexible protective frame main body 5b is located in the middle between the two gripping portions 5a, 5a and integrated, so that when the stroller A is folded, the armrest rod 3 The protection frame 5 placed at the ends of the protection frames 3 and 3 has an advantage that the protection frame main body 5b located at the center of the protection frame 5 is bent in a U shape and can be easily folded.

Further, since the conventional protective frame is formed as a rod-shaped body having the same outer shape as a whole, it is difficult for an infant having a small palm size to accurately grasp it. Since the through-holes 52, 52 for inserting fingers are formed in the grip portions 5a, 5a formed at both ends, there is an advantage that even an infant with a small palm size can grasp accurately and safely.

Particularly, when the partition wall 53 is formed in the intermediate portion of the through hole 52, the gripping efficiency can be further enhanced.

Further, in the present invention, since the non-slip structure portion 54 is formed on the surface of the grip portion 5a, there is an advantage that even a sweating infant's hand can grip the grip portion 5a accurately without slipping.
