Description

  The present invention relates to a table chair, and more particularly to a table chair that is easy to fold and is easy to carry. The table chair is a baby chair that can be attached to a table and seated by an infant.

Patent Document 1 discloses a baby chair that can be fixed to a table. Unlike a large infant chair with legs, this baby chair is not bulky, so it can be carried in a car while traveling. This baby chair is composed of a fixture composed of an upper arm and a lower arm, and a seating body having a seating part. The table is sandwiched between the fixtures and the seating body is fixed to the edge of the table. In addition, patent document 1 does not describe the storage and folding of the baby chair.
Patent Document 2 discloses a baby chair used by being attached to a table. According to FIG. 6, after the baby chair is removed from the table, the lower arm can be rotated so that it fits in the space between the two upper arms, and the height can be reduced so as not to be bulky. The lower arm is provided with a rotating pipe to be inserted into the upper arm, and a retaining screw is attached in the axial direction. However, the upper arm is an extension of the back frame of the seating part, and even when the lower arm is rotated, the length in the front-rear direction is long, and it is not easy to store and carry.

  Therefore, it is conceivable that the back frame and the upper arm are separated, a protrusion is provided on the pipe of the back frame, a locking hole is provided in the separated upper arm, and the detachable coupling is performed. However, even if the locking projection is locked in the locking hole, the upper arm does not rotate unless the locking projection is pushed back into the inside with a fingertip or the like, so that the folding operation is troublesome and difficult to use. That is, smooth rotation like the rotation pipe shown in Patent Document 2 cannot be obtained.

  An object of the present invention is to provide a table chair that can be easily folded and easily carried.

The present invention is a table chair that is attached to a table and can be seated by an infant, and includes a seating cover that covers the seating part, right and left, rearward, a back pipe that is inserted into the upper part of the seating cover, and a seat that is incorporated in the seating part. A seat body comprising a plate, a crotch belt, a safety belt for lifting the crotch belt to the left and right, and a waist belt, and a belt member attached to the seat body and detachably attached to both ends of the back pipe An upper pipe, a lower pipe welded to the upper pipe, a cap crowned on the upper pipe, and a knob provided on the lower pipe, and the back pipe includes a fixture. locking protrusions are provided at both ends, each of said upper pipe is elongated locking hole extending in the circumferential direction is provided, the locking projection of the back pipe one There protrude downward and the other projecting horizontally towards the inside, each of the upper pipe, the locking hole for receiving the locking projection, characterized in that provided at the same position both the right and left.

  A guide hole extending in the axial direction is continuously provided in the locking hole.

  The seating body is characterized in that a storage bag is sewn in a pocket provided in an outer bottom so that the storage bag can be pulled out.

According to the table chair of the present invention, the back pipe and the upper pipe are provided with a locking protrusion on one side and a long locking hole extending in the circumferential direction on the other side, and both are detachably locked. The seating body with the back pipe and the fixture with the upper pipe can be separated. That is, it can be stored smaller. The long locking hole extending in the circumferential direction can prevent the seating body from moving in the front-rear direction when the locking protrusion is engaged with the locking hole. Further, the long locking hole can easily rotate the fixing tool without pushing back the locking protrusion.
That is, if the fixture is turned inward, it can be easily carried by hanging it on the hand, and the thickness of the table chair can be reduced.

  Since one locking projection on the back pipe protrudes downward and the other locking projection on the back pipe protrudes inwardly in the horizontal direction, the locking hole of the upper pipe has a long hole. The left and right fixtures can be provided at the same position, and the left fixture and the right fixture can be a common member. There is no need to distinguish between the left fixture and the right fixture, and the management of the members is facilitated.

  Since the guide hole extending in the axial direction is continuously provided in the locking hole, when the fixture is separated from the back pipe or attached, it is not necessary to press the locking projection with your finger and push it back strongly. Can be easily done. It becomes easy to separate the fixture from the seating body, shorten the length in the front-rear direction, and reduce the storage space.

  The storage bag is sewn in the pocket on the outside bottom of the seat so that it can be pulled out, so the table bag can be stored without losing the storage bag and is convenient to carry.

  Hereinafter, a table chair according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view of a table chair 100 according to the present invention. The table chair 100 includes a seating body 9 and a fixture 4. The seating body 9 is covered with a seating cover 8 at the left, right, rear, and bottom, a U-shaped back pipe 12 is inserted into the top, and a crotch belt 7 and a waist belt 6 are provided. The fixture 4 includes a left fixture 4a and a right fixture 4b. The fixture 4 is detachably provided on the front left and right sides of the seat body 9, and fixes the seat body 9 to the table by sandwiching the table.

  The fixture 4 includes a metal upper pipe 10a and a lower pipe 10b. The upper pipe 10a is thicker than the back pipe 12, and the back pipe 12 can be removably inserted into the upper pipe 10a. A rubber cap 1 is put on the tip of the upper pipe 10a. The lower pipe 10b is a pipe that is curved in a J-shape, the upper end of which is welded to the upper pipe 10a, and the knob 3 is provided at the lower end facing upward. Since the knob 3 rises when it is rotated in one direction, the table can be sandwiched together with the cap 1. The safety belt 2 is attached to the upper part of the crotch belt 7 so that the rings on both ends pass through the upper pipe 10a and the crotch belt 7 becomes a T-shaped belt. The buckle cover 5 is provided so as to cover the front coupling portion of the waist belt 6. An extension is provided in front of the seating cover 8, and can be fastened so as to cover the legs of the lower pipe 10b with hooks.

  2A and 2B show the back pipe 12 shown in FIG. 1, in which FIG. 2A is a plan view, FIG. 2B is a front view, and FIG. 2C is a right side view. The back pipe 12 is made of metal, and a locking projection 13 is provided on the lower side of one end and the left side of the other end. The locking projection 13 is for preventing the back projection 12 from coming out after the back pipe 12 is inserted into the upper pipe 10a. The back pipe 12 has a slightly higher height on the rear side, making it easier to receive the back of the infant.

  FIG. 3 is a left side view of the right fixture 4b shown in FIG. The cap 1 is made of rubber and is provided with an anti-slip unevenness 20 at the bottom. It prevents slipping when placed on the top of the table. The knob 3 is provided with a male screw bolt (not shown) inside, and this bolt is screwed into a female screw provided on the inner periphery of the lower pipe 10b. Therefore, the knob 3 rises when turned to one side and descends when turned to the other side. As a result, the table having a thickness of 2 to 8 cm can be sandwiched and fixed. A locking hole 15 is provided at the rear end of the upper pipe 10a. The locking hole 15 is a long hole that extends in the circumferential direction and covers an angle of about 90 degrees. The locking projection 13 engages with the locking hole 15. The locking projection 13 is elastically provided on the leaf spring and can be pushed back into the pipe when pressed strongly.

  As shown in FIG. 3, the back pipe 12 is inserted inside the upper pipe 10 a by pushing the upper pipe 10 a toward the back pipe 12. At this time, the locking protrusion 13 is pressed with a finger or the like so as not to protrude. When the upper pipe 10 a and the back pipe 12 are coupled, the locking projection 13 reaches the locking hole 15. The locking projection 13 protrudes from the locking hole 15 by the elasticity of the leaf spring. In the left fixture 4a and the right fixture 4b, since the locking holes 15 of the upper pipe 10a are both at the same position, the left fixture 4a and the right fixture 4b can be interchanged left and right. The left fixture 4a is the same as the right fixture 4b shown in FIG.

  FIG. 4 is a cross-sectional view showing the relationship between the locking protrusion 13 and the locking hole 15. FIG. 4A shows a case in which the left fixing tool 4a and the right fixing tool 4b are facing directly below, and FIG. It is sectional drawing which shows the case where the tool 4a and the right fixing tool 4b are rotated inside. The position of the cross section is the position indicated by AA in FIG. The case where the locking hole 15 as shown in the drawing circle of FIG. As shown in FIG. 4A, in the left fixture 4 a, the locking protrusion 13 is attached to the back pipe 12 so as to face downward, so that the locking protrusion 13 is positioned at the lower end of the locking hole 15. On the other hand, in the right fixture 4 b, the locking projection 13 is attached facing the left direction, so that the locking projection 13 is positioned at the upper end of the locking hole 15. The triangle mark indicates the position of the upper end of the locking hole 15. As shown in FIG. 4B, when the left fixture 4a is turned inward, the locking hole 15 is turned about 90 degrees counterclockwise. The locking projection 13 comes to the position of the upper end (triangular mark) of the locking hole 15. On the other hand, when the right fixture 4b is turned inward, the locking hole 15 is turned about 90 degrees clockwise. The locking projection 13 comes to the position of the lower end of the locking hole 15.

  FIG. 5 is a view in which the fixing tool 4 is turned inward and folded. As shown by a circle 1, the right fixture 4b is turned inward, and as shown by a circle 2, the left fixture 4a is turned inward. In this case, since the curved lower pipes 10b and 10b cross each other, the table chair 100 can be hung and carried easily by hand. When the right fixing tool 4b and the left fixing tool 4a are rotated, that is, the lower pipes 10b and 10b are rotated and the seating cover 9 is folded, the thickness of the seating body 9 is reduced.

  FIG. 6 is an explanatory diagram when the guide hole 14 is continuously provided in the locking hole 15. (A) is a right perspective view, (B) is a left perspective view. A case where the guide hole 14 is provided continuously with the locking hole 15 is referred to as a configuration example 2 of the locking hole. In the configuration example 2, since the guide hole 14 is continuously provided in the locking hole 15, the fixing tool 4 can be easily attached and detached. Moreover, the left fixture 4a and the right fixture 4b can be used as a common member. The locking hole 15 extends in the circumferential direction and has a length that covers an angle of about 180 degrees. On the other hand, since the guide hole 14 is opened at the end of the upper pipe 10a, the locking protrusion 13 can be easily inserted. The guide hole 14 may be a semicircular cylindrical shape as long as the locking projection can pass therethrough.

  FIG. 7 is a cross-sectional view showing the relationship between the locking protrusion 13 and the locking hole 15. FIG. 7A shows a case where the left fixing tool 4a and the right fixing tool 4b face downward, and FIG. (C) is sectional drawing which shows the case where the left fixing tool 4a and the right fixing tool 4b are removed from the back pipe 12 when the fixing tool 4a and the right fixing tool 4b are rotated inward. As shown in FIG. 7A, in the left fixture 4a, the locking protrusion 13 is attached to the back pipe 12 so as to face downward, so that the locking protrusion 13 is positioned at the lower end of the locking hole 15. On the other hand, since the locking protrusion 13 is attached to the right fixture 4 b so as to face the left direction, the locking protrusion 13 is located at an intermediate point of the locking hole 15. The black triangle mark indicates the position of the upper end of the locking hole 15. A guide hole 14 is provided at this position.

  As shown in FIG. 7B, when the left fixture 4a is turned inward, the locking hole 15 is turned about 90 degrees counterclockwise. The locking projection 13 comes to an intermediate point of the locking hole 15. On the other hand, in the right fixture 4b, when the right fixture 4b is turned inward, the locking hole 15 is turned about 90 degrees clockwise. The locking projection 13 comes to the lower end position of the locking hole 15. Thereby, the left fixture 4a and the right fixture 4b can be folded.

  As shown in FIG. 7C, it is assumed that the left fixture 4a is further rotated 90 degrees counterclockwise. In that case, the locking hole 15 rotates, and the upper end (black triangle mark) of the locking hole 15 comes to the position of the locking projection 13. Therefore, the latching protrusion 13 can pass through the guide hole 14 of the left fixture 4 a and can be separated from the back pipe 12. On the other hand, it is assumed that the right fixture 4b is rotated about 180 degrees counterclockwise from the state of FIG. In that case, the locking hole 15 rotates, and the upper end (black triangle mark) of the locking hole 15 comes to the position of the locking projection 13. Therefore, the locking protrusion 13 can pass through the guide hole 14 of the right fixture 4b and can be separated from the back pipe 12.

  FIG. 8 is an explanatory diagram when the fixture 4 is separated from the seating body 9. As shown by circle 1, the right fixture 4 b is rotated and pulled out as shown by circle 2. Similarly, the left fixture 4 a is rotated as indicated by a circle 3 and pulled out as indicated by a circle 4. A pocket is provided on the bottom surface of the seating body 9, and a storage bag 19 is sewn. When this is pulled out, the storage bag 19 is in an inverted state. The storage bag 19 is turned over to store the table chair 100.

  FIG. 9 is an explanatory diagram when the table chair 100 is stored in the storage bag 19. As shown in FIG. 9, since the fixture 4 is detached from the back pipe 12, the left fixture 4 a and the right fixture 4 b can be stored in the storage bag 19 separately from the seating body 9. The depth of the storage bag 19 is about 20 cm, and can be reduced to half the length when the fixture 4 is not removed from the back pipe 12.

  FIG. 10 is a perspective view of the seat plate 16. The seat plate 16 is a bag body in which a base plate and a cushion material are housed. The seating body 9 is provided with a pocket for the seat plate 16, and the seat plate 16 is accommodated therein. When the seat plate 16 is taken out and the back pipe 12 is further pulled out from the seating cover 8, the seating body 9 is made only of the cloth material and can be stored smaller.

  FIG. 11 is a perspective view of a portion where the crotch belt 7 and the waist belt 6 are coupled. The waist belt 6 is joined to the left and right ends by buckles 17. The buckle 17 is connected to the crotch belt 7. The safety belt 2 is sewn on the crotch belt 7. Rings 2a are provided at the left and right ends of the safety belt 2 and pass through the upper pipe 10a. The buckle cover 5 is hooked over the buckle 17.

  FIG. 12 is a perspective view when the table chair 100 is attached to the table 21. Since the buckle cover 5 covers the buckle 17, it is possible to prevent an infant's finger from being caught by the buckle 17. The table chair 100 can be securely fixed to the table 21 with the cap 1 and the knob 3. The crotch belt 7 can prevent the infant from sliding down. The waist belt 6 can prevent the infant from slipping out onto the table 21.

  The present invention is suitable as a table chair that is easy to carry and can be stored compactly. In this embodiment, the back pipe is provided with a locking projection and the upper pipe is provided with a locking hole. However, the reverse back pipe is provided with a locking hole and the upper pipe is provided with a locking projection. It is also possible to adopt a configuration in which the upper pipe is inserted into the inside.
