Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an infant chair having a backrest made of metal pipe, the infant chair having a backrest.

[0002]

[Prior art]

 Chairs for infants made mainly of metal pipes are made by cutting, bending, and welding metal pipes such as iron pipes to produce a skeleton body consisting of legs, backrest, armrests, and seat plate attachment parts. A seat plate is manufactured by stacking a foam synthetic resin plate such as urethane foam on a molded plate with stiffening ribs of rigid synthetic resin such as, and covering these with a synthetic resin sheet such as vinyl chloride. A seat plate containing a foam synthetic resin plate that serves as a cushion is fixed to the seat plate mounting part of the body.

[0003]

[Problems to be solved by the device]

 However, in the infant chair as described above, the backrest is made of only metal pipes, unlike a seatboard with a foamed synthetic resin plate that serves as a cushion, so there is almost no elasticity or cushioning, and the chair sits on the chair. The back of the infant is strong.

Therefore, in order to impart elasticity or cushioning property to the backrest, it is conceivable to replace the metal pipe with a structure similar to a seat plate in which a molded plate of hard synthetic resin and a foamed synthetic resin plate are stacked. However, if this is done, the structure will not be simple, and the manufacturing process will increase and the cost will increase.

[0005]

[Means for Solving the Problems]

 According to the present invention, a skeleton body having a backrest and a seat plate attachment portion is formed of a metal pipe, and a seat plate is fixed to the seat plate attachment portion of the skeleton body, and a cushion is provided on the front surface of the metal pipe backrest. Arrange a backing pad covered with a foamed synthetic resin plate with a synthetic resin sheet, and pierce through the pair of mounting holes formed in the backing pad with the C-shaped cross-section fasteners to the metal pipe behind the backing pad. It is an infant chair with a backrest that is fitted and attached to the metal pipe of the backrest with a fastener.

Further, the fastener is a baby chair with a backrest characterized in that the backrest can be detached from the metal pipe of the backrest and the backrest can be detached from the front surface of the backrest.

[0007]

[Effect of the invention]

 In the infant chair with a backrest, the metal pipe backrest has elasticity or cushioning because the backrest that serves as a cushion is arranged in front of the backrest, and the back of the infant sitting in the chair has a weak contact.

Further, the backrest is formed by covering a foamed synthetic resin plate serving as a cushion with a synthetic resin sheet, and is fitted into a metal pipe on the rear side of the backrest by penetrating through a pair of mounting holes formed therein. Since it is attached with a C-shaped cross-section fastener, the structure is simple and not expensive.

When the backrest does not require elasticity or cushioning, the backrest can be removed from the backrest.

[Embodiment of the invention]

 As shown in FIG. 1, the infant chair with a backrest is composed of a metal rod skeleton body including front and rear left and right legs 1 and 2, a backrest 3, left and right armrests 4, and left and right seat plate attachment portions 5, and a composite body. The seat plate 6 is made of resin, and the backrest 11 is made of synthetic resin.

As shown in FIGS. 1 and 2, the skeleton body includes a front member 1 on the left and right, a first member constituting an upper part of the left and right armrests 4 and a backrest 3, and a rear leg 2 on the right or left side. The two second members forming the right or left part of the backrest 3 and the two third members forming the right or left seat plate attachment part 5 are respectively cut and bent of a metal pipe such as an iron pipe. Formed by welding one first member, two second members and two third members, and a plurality of wire-like metal wires between the right part, the left part and the upper part of the backrest 3. 7 is fixed vertically and horizontally.

The seat plate 6 is formed by stacking a foam synthetic resin plate such as urethane foam on a molded plate with a reinforcing rib made of hard synthetic resin such as polypropylene, and covering them with a synthetic resin sheet such as vinyl chloride. There is.

As shown in FIGS. 1 and 2, a seat plate 6 is placed on the left and right seat plate mounting portions 5 of the skeleton body, and bolts 8 penetrating the left and right seat plate mounting portions 5 are seated respectively. The seat plate 6 is fixed onto the left and right seat plate mounting portions 5 by being screwed into the left and right side parts of the plate 6. Protective caps 9 made of synthetic resin are fitted on the lower ends of the legs 1, 2 on the front, back, left and right of the skeleton.

The back support 11 is formed by covering a foamed synthetic resin plate such as urethane foam with a synthetic resin sheet such as vinyl chloride to form a horizontally long rectangular plate shape. As shown in FIGS. 3 and 4, the right end portion is formed. And a pair of upper and lower elongated mounting holes 12 are respectively penetrated to the left end portion and the left end portion.

The fastener 13 of the back support 11 is a molded product of elastic synthetic resin such as Duracon, and has a C-shaped cross-section that fits into the metal pipe of the backrest 3, as shown in FIG.

On the front surface of the upper portion of the backrest 3 made of a metal pipe, as shown in FIGS. 1 and 2, a back support 11 is arranged in a curved shape along the metal pipe, and a pair of right end portions of the back support 11 are attached. The C-shaped cross-section fastener 13 penetrating the hole 12 and the C-shaped cross-section fastener 13 penetrating the pair of mounting holes 12 at the left end of the back support 11 are respectively attached to the spine as shown in FIG. The back support 11 is removably fitted to the metal pipe on the rear side of the backing 11, and the back support 11 is detachably attached to the metal pipe above the backrest 3 by the left and right fasteners 13.

When an infant sits in this infant chair with a backrest, the back of the infant hits the backrest 11 on the upper front surface of the backrest 3, and the backrest 11 serves as a cushion, so that the back of the infant hits weakly.

When the upper part of the backrest 3 does not need elasticity or cushioning property, the left and right fasteners 13 of the backrest 11 are removed from the metal pipes on the upper part of the backrest 3 respectively, and the backrest 11 is lifted on the upper part of the backrest 3. Remove from.
