Description

  The present invention relates to an armchair that can be stacked.

Conventionally, a chair that can be stacked (stacked) with a chair having a simple material and a structure usually does not have an armrest.
FIG. 5 is a chair disclosed in Patent Document 1 below. In Patent Document 1, various methods that enable stacking of chairs made of simple materials and structures are presented, but many chairs without armrests are disclosed except for special cases of special shapes.

  Further, in Patent Document 2 below, based on a technical background that “a chair that can be stacked (stacked) or stored in a front and rear combination (nesting) is not provided with an armrest”, it is made of metal. Alternatively, an armchair having a complicated structure made of a synthetic resin is disclosed.

  However, in a childcare chair used in a childcare facility or the like, a wooden chair having softness and warmth is desirable, and an armrest is an important function considered to be indispensable from the viewpoint of ensuring safety. In addition, by making stacking possible, reducing the storage space necessary for storage is also an extremely important requirement in childcare facilities that handle a large number of infants.

  6 and 7 are chairs disclosed in Patent Document 3 below. In FIG. 7, the chair 1 includes a seat plate 4, pedestals 2 </ b> A, 2 </ b> B, 2 </ b> C, 2 </ b> D, a backrest 3, and armrests 5 </ b> A, 5 </ b> B. This chair 1 can be stacked by placing the seat plate 4 slightly inside, bending the armrests 5A, 5B outward, and further ramping the pillars 2A, 2B, 2C, 2D slightly upward and downward. Yes. As a result of such a structure, both the structure and shape are considerably complicated. In addition, the shape and structure are complex, and infants and infants are likely to be entangled with their heads and limbs, leading to an accident, which is difficult for infants to use.

  FIG. 8 is a metal armchair disclosed in Patent Document 4 below. This chair allows stacking by curving the armrests outward in a special shape. In this way, the shape and structure are complicated. Further, the armrest is curved outward to form a protruding portion, which is difficult for infants to use.

Japanese Patent No. 2791221 JP 2001-128775 A Registered Utility Model No. 3072172 Japanese Patent Application Laid-Open No. 2005-073987

  In the case of childcare for use in childcare facilities, etc., softness and warmth of solid wood are desirable. In addition, armresting is an important function that is considered indispensable for ensuring safety. However, as mentioned above, a chair of simple material and structure that can be stacked does not have an armrest. On the other hand, those that can be stacked with armrests are complicated in shape and structure and may cause accidents such as entanglement of the head and limbs, and are not suitable for use in childcare facilities.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an armchair that can be easily manufactured from natural wood and that is stacked with an extremely simple structure.

In order to achieve the above object, an armchair according to the present invention is an armchair provided with four corner leg members for supporting a seat member and left and right armrest plates,
The armrest plate is arranged upright on the left and right sides of the seat member,
Each of the pedestal members is disposed outside the seat member and the armrest plate, and fixed in contact with the outer surface of the armrest plate,
The above-mentioned armrest plate is configured to have a state in which the upper and lower end surfaces are abutted when stacked, a state in which the upper end surface and the lower end surface are abutted, a state in which the upper end surfaces are abutted and a state in which the lower end surfaces are abutted It is a summary.

  The armchair of the present invention can be in a state where the upper and lower end surfaces are abutted when stacked, a state where the upper end surface and the lower end surface are abutted, a state where the upper end surfaces are abutted, and a state where the lower end surfaces are abutted It is configured. For this reason, by stacking the upper end surface and the lower end surface so as to be brought into contact with each other, a plurality of armchairs can be stacked and stacked in the same upward state as when sitting. In addition, it is possible to stack a high amount in a small area by further stacking a combination in which the upper end surfaces are butted together so that the lower end surfaces are butted. In this way, forward stacking in which the vertical direction and the front-rear direction are both the same direction can be performed in a forward direction, and reverse stacking can be performed in which the vertical direction and the front-rear direction are stacked in the reverse direction. Therefore, the stacking method can be selected according to the storage conditions.

  Further, the armrest plate is arranged such that the armrest plate stands on the left and right of the seat surface member, and each of the pedestal members is disposed outside the seat surface member and the armrest plate and is in contact with the outer surface of the armrest plate. It is fixed. For this reason, when stacking, the left and right pedestal members of the upper chair are arranged between the front and rear pedestal members of the lower chair or in front of or behind them, and in this state the pedestal is placed on the outer surface of the armrest plate. The inner surfaces of the members face each other and come into contact with each other, and stability during stacking is ensured.

  To explain in detail, the present invention is formed, for example, on both sides by connecting the front and rear pedestal members upright by means of an armrest plate, and connecting them with a seating surface member and a backrest as required. It is an armchair with simple materials and structure that can be obtained. Further, for example, the four pedestal members can be connected and integrated by connecting the seat plate member and the backrest as needed, and placing the armrest plates upright on the left and right sides of the member. Thus, it is an armchair with a simple material and structure.

  As described above, according to the present invention, it can be generally constituted by a pedestal, a seat plate, an armrest member, and, if necessary, a backrest material. It is possible to provide an armchair with a simple material and structure that can be stacked (stacked) with stability and is suitable for storage.

  The above-mentioned armchair is a method of stacking the upper and lower directions and the front-rear direction in the same direction (forward stacking method), and the method of stacking the upper and lower directions and the front-rear direction one by one in reverse (reverse stacking method). The stacking method can be selected according to the purpose of storage.

  Therefore, since the above-described forward stacking method and reverse stacking method are possible, the stacking method can be selected and stacked according to conditions such as a storage area or a storage volume and stability allowed during storage.

  Since the above-mentioned sequential stacking method can stack several units in the same direction in the same direction on the wall or the like, it is simple and easy as a stacking method, and can be adopted as a suitable stacking method when the storage area is allowed. .

  On the other hand, in the reverse stacking method, the stacked result is vertical, and the number of steps can be increased. In addition, the present method can be extended horizontally on the floor, and the number of stages can be increased, the storage volume can be reduced and the stack can be stably stacked, and efficient storage is possible. Therefore, the stacking method is particularly suitable for long-term storage or transportation.

Further, the armchair according to the present invention has a simple material and structure, and has a small number of materials to be constructed. As a result, the number of manufacturing steps can be minimized.

It is a figure explaining the time of stacking of the said armchair chair (reverse stacking method). It is a perspective view which shows other embodiment of the armchair of this invention. It is a perspective view which shows an example of the stacking state of the chair of a prior art example. It is a perspective view which shows the stacking state of the armchair of a prior art example. It is a perspective view which shows the said armrest chair. It is a perspective view which shows an example of the metal armchair of a prior art example.

  Hereinafter, embodiments of the armchair of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows an embodiment of an armchair according to the present invention, wherein (A) is a first mode and (B) is a second mode.

  In this example, the armchair is made of wood and includes leg pillar members 11A, 11B, 11C, and 11D for supporting the seat member 10, and left and right armrest plates 12.

  In this example, the four corner leg members 11A, 11B, 11C, and 11D can be formed by cutting a square bar into a predetermined length. Of the four corner leg members 11A, 11B, 11C, and 11D, the rear leg members 11C and 11D are longer than the front leg members 11A and 11B, and the rear leg members A plate-like backrest 13 is attached to the top of the members 11C and 11D.

  The armrest plate 12 is arranged upright on the left and right sides of the seat member 10. Further, each of the pillar members 11 </ b> A, 11 </ b> B, 11 </ b> C, and 11 </ b> D is disposed outside the seat member 10 and the armrest plate 12 and fixed in contact with the outer surface of the armrest plate 12. In this example, the seat member 10 has a square plate shape, and the armrest plate 12 also has a rectangular plate shape.

  In this state, leg portions 11 </ b> A, 11 </ b> B, 11 </ b> C, and 11 </ b> D form leg portions that protrude downward from the seat member 10 and the armrest plate 12. In addition, a region surrounded by the upper surface of the seat member 10 and the inner surfaces of both the armrest plates 12 is a space for accommodating the collar portion.

  As described above, the armchair includes the four vertical legs 11A, 11B, 11C, and 11D, the seat member 10, the backrest 13, and the two armrest plates 12.

  In FIG. 1A, a pair of front and rear leg pillar members 11B and 11D arranged on the right side are positioned so that an armrest plate 12 arranged upright is in contact with the inside of each leg pillar member 11B and 11D. The plates 12 are connected together to form a right unit. Similarly, a pair of front and rear leg pillar members 11A and 11C arranged on the left side are positioned so that the armrest plate 12 arranged upright is in contact with the inside of each leg pillar member 11A and 11C, and is connected by the armrest plate 12 to be integrated. Thus, the left unit is formed. The right unit and the left unit can be connected by the seat member 10 and the backrest 13 to constitute an armchair.

  In FIG. 1B, four pedestal members 11A, 11B, 11C, and 11D are connected by a seat member 10 and a backrest 13 to form an integral unit. An armchair can be constructed by connecting the plates 12 in an upright state.

  In the armchair, the armrest plate 12 takes a state in which the upper and lower end surfaces are abutted when stacked, a state in which the upper end surface 14 and the lower end surface 15 are abutted, a state in which the upper end surfaces 14 are abutted with each other, and the lower end surfaces 15 It is comprised so that the state which can butt can be taken. As a result, both the vertical stacking method and the front-rear direction are stacked in the same direction (forward stacking method) and the vertical stacking method and the front-rear direction are stacked in the reverse direction (reverse stacking method). Enable the method.

  Thus, the pillar members 11A, 11B, 11C, and 11D are arranged so as to be positioned outside the seat member 10, the backrest 13, and the armrest plate 12, and the pillar members 11A, 11B, 11C, and 11D and the armrest plate 12 are disposed. Make contact with a vertical plane. Further, when stacked, the upper end surface 14 and the lower end surface 15 of the armrest plate 12 are configured to be in contact with each other. Further, when stacking, the upper end surfaces 14 of the armrests 12 can be brought into contact with each other, the upper end surface 14 and the lower end surface 15 can be brought into contact with each other, and the lower end surfaces 15 can be brought into contact with each other. The outer surface of the plate 12 is configured to be restrained by the inner surfaces of the pillar members 11A, 11B, 11C, and 11D, and the stability at the time of stacking is further increased.

  FIG. 2 is a diagram for explaining the sequential stacking method.

  In this method, the armchairs are stacked one by one with the armchairs in the same direction in the vertical direction and the front-rear direction. At this time, the upper end surface 14 and the lower end surface 15 of the armrest plate 12 are brought into contact with each other.

  In this case, the stacking position moves forward by the front-rear direction width of each of the pillar members 11A, 11B, 11C, and 11D for each unit. As a result, the center of gravity as the stack is also stacked one by one. As a result, it moves in the forward direction, and the stack height (number of stages) is limited. In this case, stabilization can be achieved by stacking the chairs so that the front direction faces the wall.

  The above-described sequential stacking method is simple as a stacking method and can be easily used. However, depending on the stacking, the stacking position moves forward by the front-back width of the pedestal member each time one unit is stacked. The center of gravity moves sequentially forward. As a result, the stacking height (number of steps) is limited, but if it is within that limit, it can be stacked and stored very easily after use, and it is extremely easy to line up to use the stored chairs. Easy.

  FIG. 3 is a diagram for explaining the reverse stacking method.

  In this reverse stacking method, first, one is inverted and placed on the other so that the backrest 13 of the two armchairs and the seat member 10 face each other. At this time, the upper end surfaces 14 of the upper and lower armrests 12 of the chairs are brought into contact with each other. Then, a chair that is not inverted is placed on the chair that is inverted and placed on top. At this time, the lower end surfaces 15 of the armrest plate 12 are brought into abutment with each other. Thereafter, the placement state in which the upper end surfaces 14 of the armrest plate 12 are abutted with each other and the placement state in which the lower end surfaces 15 of the armrest plate 12 are abutted are alternately repeated. Accordingly, the chairs are alternately stacked in the forward direction, the reverse direction, the forward direction, the reverse direction, and so on.

  Such a reverse stacking method does not cause the movement of the center of gravity unlike the forward stacking method, so that the minimum storage area or storage volume and stability can be realized. It is also possible to adopt a suitable stacking method even during time or long-term storage.

  Moreover, a vertical square can be used as a pedestal, and the armrest plate 12 can also be a flat plate. By doing so, it is possible to minimize the waste of space at the time of stacking, and to support these flat materials to support each other, thereby achieving further stabilization at the time of stacking. Moreover, as a raw material, a simple shape wood, such as a square and a flat plate, or a synthetic resin material can be used. As a result, the structure is simplified, and an armchair that does not require complicated processing and manufacturing processes can be provided.

  The armchair of the present embodiment is configured such that the pedestal has a square bar shape and the armrest member has a flat plate shape so that the armrest members are in contact with each other, and the contacting portion is formed in a vertical shape. Both the method of stacking forward and backward with the same direction (forward stacking method) and the method of stacking the vertical direction and the front-rear direction one by one in reverse (reverse stacking method) are both stacked. It was possible to select a stacking method according to the storage conditions.

  FIG. 4A shows a second embodiment. As shown in the figure, when there is a possibility that the head of the infant enters between the seat member 10 and the backrest 13, for safety, a horizontal rail 20 may be provided to prevent the insertion of the head of the infant. it can.

  FIG. 4B shows a third embodiment. As shown in the figure, an opening 21 can be provided in the armrest plate 12 to improve the ventilation state.

FIG. 4C shows a fourth embodiment. As shown in the figure, by tilting the seat member 10 so that the front portion is slightly higher, the seat surface member 10 can be gently inclined to the rear to stabilize the sitting.

  In the embodiment of the armchair according to the present invention, the size of the infant armchair was 360 mm in horizontal dimension, 280 mm in vertical dimension, and 400 mm in height. In this case, in the stacking by the sequential stacking method, the required volume at the time of stacking was 360 mm in the horizontal dimension, 530 mm in the vertical dimension, 6 stacked units, and 1 m in height. It can be considered as a stacking method that can be easily used in a corner of a normal nursery room.

  In the case of the reverse stacking method, the required volume at the time of stacking was 360 mm in the horizontal dimension, 380 mm in the vertical dimension, 12 stacked units, and the stacking height was 1.8 m. If a stepladder is used in a warehouse, it can be stacked up to near the ceiling height. This reverse stacking method can be stacked in the vertical direction as described above, but can also be stacked in the horizontal (horizontal) direction by the same reverse stacking method. Depending on the state of stacking, it can be selected and used as appropriate, but this lateral reverse stacking method is often suitable especially during transport.

  The present invention is suitable for the use of natural timber supplied from mountainous areas, especially thinned wood, and it is expected that nursery wooden armchairs composed of solid wood will be the main destination.

  Further, the armchair according to the present invention can be a chair with a simple structure, and therefore can be provided as an assembly chair that can be assembled at home.

Further, it can be made of a synthetic resin, so that the weight of the product can be reduced and the product price can be reduced.
