Description

  The present invention relates to a rotary storage table for a chair such as a bleacher seat.

  There are cases where a small table for writing or eating and drinking is added to a bleacher seat provided in a theater or a stadium.

Some bleachers have an integrated back and seat, and some have a separate back and seat. In addition, there are things that do not get in the way when other people pass through the seat jumping up, but in any chair, since the person is seated basically, when adding a table In order to place the table in a range where the hand can reach naturally without hitting the person's belly, the table is at a height approximating the height of the elbow rest and is used in a substantially horizontal posture slightly ahead of the seated person (For example, refer to Patent Document 1).
JP 2003-79480 A

  However, since the seats are usually arranged in a row in which a plurality of seats are connected to the left and right, and several rows are arranged in front and back, if the table is fixed in use, The table gets in the way as people pass between the rows.

  Therefore, as described in Patent Document 1, it is common to have a structure in which the table is rotated and stored under the seat so as to widen the passage and prevent the movement of people when sitting. However, the conventional rotating storage structure has a problem that it is complicated and large, expensive, complicated in appearance, easily damaged by moving parts, and uncomfortable for the seated person. .

  Therefore, the present invention reduces the cost by making the rotary storage structure of the table simple and compact, keeps the appearance beautiful, prevents the movable part from being damaged, and makes the seated person feel comfortable. The purpose is that.

The present invention has been made in order to solve the above-mentioned problems advantageously, and a pivot storage type table for a chair according to the present invention is fixed to a chair, and is a table receiver positioned on the side of the chair seat. The table bearing is pivotally supported about a first axis extending in the left-right direction of the chair and is parallel to a vertical plane extending in the front-rear direction of the chair on the table bearing. A table main body pivotally supported between a use posture extending parallel to the first axis and a storage posture extending parallel to the vertical plane around a second axis extending to The table support includes a table main body support section and a table main body posture control section, and the table main body support section includes a predetermined bearing around the first axis. Located in the pivot position The table main body is allowed to rotate up to the use posture around the second axis of the table body, and the table main body is put into a use state by supporting the back surface of the table main body in the use posture. The table main body attitude control unit is configured to allow the table bearing to rotate from the predetermined rotation position around the first axis to the storage attitude by slidingly contacting a back surface of the table main body. A perpendicular line dropped from the attitude control unit to the first axis is longer than a perpendicular line dropped from the table main body support unit to the first axis, and the table main body support unit and the table main body attitude control unit are fitted to the table holder. It is characterized in that it is formed by a plastic member that is worn and extends between the table bearing and the table bearing .

  In such a pivotable storage table for a chair, a seated person holds the table body in the storage posture stored below the table receiver located on the side of the chair seat and rotates it upward to lift it upward. Thus, when the table bearing is rotated around the first axis and positioned at a predetermined rotation position where, for example, the second axis is horizontal, the table body support portion of the table receiver is only at the rotation position of the table bearing. The table body is allowed to rotate around the second axis without interfering with the table body, and the back surface of the table body rotated to the use position is supported. Maintain the usage state.

  Further, when the seat occupant pushes the table body in the use posture and the use state forward, the table bearing is rotated around the first axis in the predetermined direction in which the table body moves from the predetermined rotation position to the front of the chair. Then, as the table bearing rotates around the first axis, the table main body attitude control unit of the table receiver functions like a cam and slides on the back surface of the table main body corresponding to the follower. It is raised from the use posture around the second axis and rotated to the stowed posture, so that the table body becomes parallel to the vertical plane (virtual plane) extending in the front-rear direction of the chair and moves forward with the table bearing by its own weight. , And further downward, and is stored below the table receiver located on the side of the chair seat.

  Therefore, according to the pivot storage table for a chair of the present invention, the table body can be placed in front of the seated person when the table is used, and the table body can be used when the table is not used or when a person passes. The rotary storage table that can be stored under the table receiver located on the side of the chair seat can be mainly composed of three parts: a table receiver, a table bearing, and a table body. The dynamic storage structure can be made simple and compact, the cost can be reduced, and the appearance can be made beautiful and not complicated.

In the pivot storage table for a chair according to the present invention, the table body support part and the table body posture control part are fitted to the table holder and extend between the table holder and the table bearing. It is formed by existing plastic members, and in this way, the table body as a movable part can be prevented from being damaged, and the comfortable feeling of the seated person can be made comfortable by the smooth and warm touch of the plastic members. In addition, the number of parts can be reduced and costs can be reduced as compared with the case where the table main body support section and the table main body posture control section are manufactured by separate members, and a plastic member is molded. This improves the dimensional stability and eliminates the need for adjustments such as leveling when the table body is in use after the table is assembled. .

  Moreover, in the pivot storage type table for chairs of this invention, the said table main body is the said use state, The front end part near the other end part on the opposite side rather than the one end part pivotally supported by the said table bearing is said one end part. While projecting forward from the front end portion in the vicinity, the rear end portion near the other end portion may be retracted forward from the rear end portion in the vicinity of the one end portion. In use, it is easy to use because it is located in front of the occupant and away from the occupant, and in the stowed state, it rotates approximately 180 degrees around the first axis and is opposite to one end pivotally supported by the table bearing. Since the front end near the other end on the side protrudes rearward from the front end near the one end, the rear end near the other end retracts behind the rear end near the one end. Do not obstruct the traffic of the person in front of the chair , It can be retracted larger.

  Furthermore, in the pivotable retractable table for a chair according to the present invention, the table bearing is in contact with the table main body and is on the side opposite to the use posture that exceeds the storage posture around the second axis of the table main body. A table main body stopper that restricts the rotation of the table main body may be provided, and in this way, the table main body can be prevented from falling into the adjacent chair side.

  And in the rotation storing type table for chairs of this invention, the said table receiver contact | abuts to the said table main body or the said table bearing, and the direction opposite to the said predetermined direction exceeding the said predetermined rotation position of the table bearing. And a table receiving stopper for restricting the rotation of the table bearing in the predetermined direction within a predetermined limit. In this way, with a simple configuration, the table body and Excessive rotation around the first axis of the table bearing can be restrained.

  As shown in FIGS. 9 to 11 to be described later, the pivotable storage table 1 for this embodiment is mounted as a table unit on, for example, a seat standing type connecting chair 12 used for a viewing seat or the like. As shown in FIGS. 1 to 5, the main part includes a table receiver 2, a table bearing 3, and a table body 4, and the table receiver 2 is fitted with a sliding contact member 5. is doing.

  The table body 4 may be composed of a wood or plastic table plate and a hardware part that supports it, but is preferably a molded product in which the table plate 4a and the hinge portion 4b are integrated. Thereby, cost can be reduced. And productivity can also be improved significantly by setting it as an aluminum alloy die-casting or a reinforced plastic injection molded product. A through hole 4c is provided in the hinge part 4b located at one end of the side of the table body 4 in parallel with the surface of the table plate 4a.

  Here, in the state of use shown in FIG. 1C and FIG. 9 described later, the table plate 4a has a front end near the other end on the opposite side of the hinge 4b than a front end near the hinge 4b. In addition, the rear end portion near the other end is retracted further forward than the rear end portion in the vicinity of the hinge portion 4b.

  The table bearing 3 serves as a support portion when the table body 4 is rotated and stored. As shown in FIG. 5, the hinge portion 3a that fits between the two hinge portions 4b of the table body 4. 5A, a through hole 3b extending in the left-right direction, and a shaft hole 3c extending downward in the direction perpendicular to the paper surface in FIG. 5A of the hinge portion 3a are provided. The through hole 3b of the hinge part 3a and the through hole 4c of the hinge part 4b of the table body 4 are aligned and the pin 6 is inserted therethrough, so that the table body 4 is assembled rotatably. In the illustrated example, the assembly of the table bearing 3 and the table body 4 is facilitated by inserting two pins 6 from both sides of the table body 4 so as to penetrate the table bearing 3 and the table body 4. You may assemble using the pin 6 which penetrates the table bearing 3 and the table main body 4. FIG. The central axis of these through holes 3b and 4c is the second axis. Further, the table bearing 3 is rotatably assembled to the table receiver 2 by fastening the storage shaft 7 inserted into the shaft hole 3c to the table receiver 2. The central axis of the shaft hole 3c is the first axis.

  Here, when the hinge portion 3a is positioned above the shaft hole 3c, the hinge portion 3a is provided so as to be offset from the symmetrical position with respect to the shaft hole 3c to the front of the chair (to the right in FIG. 5A). Thereby, when the table bearing 3 is stored 180 degrees rotated from the posture of FIG. 5A, that is, when the hinge portion 3a is positioned below the shaft hole 3c, the hinge portion 3a relates to the shaft hole 3c. By offsetting from the symmetrical position to the back of the chair, the table body 4 fits compactly. Further, as shown in FIGS. 1B to 1D, the cross-sectional shape of the hinge portion 3a is rounded into a cylindrical shape on the side facing the table receiver 2, but the corner portion 3d is formed on the side facing away from the table receiver 2. Leave it. As a result, as shown in FIG. 1 (d), even if the table body 4 is about to fall from the storage posture to the side opposite to the use posture side, the corner portion 3 d is located between the two hinge portions 4 b of the table body 4. It functions as a table body stopper that abuts against the portion and prevents the table body 4 from falling down. Further, a spring pin is preferably used for the pin 6 in order to give an appropriate resistance to the rotation of the table body 4 with respect to the table bearing 3. Further, a plastic bush 8 is preferably interposed between the table body 4 and the pins 6 so that the table body 4 rotates smoothly and wear is reduced.

  The table receiver 2 is fixed to a chair with a bolt and supports the table bearing 3 so as to be rotatable. In addition to the three bolt holes 2a, a female screw for fastening the storage shaft 7 is formed. And a screw hole 2c in which a female screw for fastening a stopper fixing screw 10 for fixing a stopper 9 described later is formed. When the storage shaft 7 is fastened in the screw hole 2b of the table bearing 2, the table bearing 3 is preferably made of plastic between the table bearing 3 and the storage shaft 7 so that the table bearing 3 rotates smoothly and wear is reduced. A bush 11 is interposed.

  As shown in FIGS. 1A and 4, the sliding contact member 5 includes a table body support portion 5a which is an upward horizontal surface in this embodiment, and a horizontal surface of the table body support portion 5a in this embodiment. Smoothly on the horizontal plane away from the central axis by a distance D2 that is always larger than the distance D1 from the central axis of the storage shaft 7 but changes according to the angle from the vertical line of the straight line connecting the central axis and the target position. A table body posture control unit 5b which is a convex curved surface whose direction changes from continuous upward to forward and obliquely downward, and a side surface which slides on the table bearing 3 and the table main body 4 to guide their rotation around the storage shaft 7. A plastic integral cap for providing a certain guide portion 5c to the table receiver 2, which is closely fitted to the table receiver 2, To be fixed to the second receiving table by the stopper fixing screw 10 is secured pressed against the 2 also table received by the table bearing 3 at the same time.

  Here, as shown in FIG. 1A, the table body support portion 5a has the table bearing 3 around the storage shaft 7 (around the first axis), and the through-holes 3b and 4c and the central axis of the pin 6 are at the storage shaft 7. As shown in FIG. 1 (c), the table body 4 around the pin 6 (around the second axis) is not interfered with the table body 4 as shown in FIG. In this case, the table body 4 is bent at a right angle with respect to the table bearing 3 (that is, the surface of the table main body 4 extends in parallel with the first axis). The table body 4 is supported and put into a use state in which the surface of the table body 4 is horizontal.

  Further, here, as shown in FIG. 6A, the table body posture control unit 5b is configured such that the table bearing 3 is located around the storage shaft 7 (around the first axis) from the predetermined rotation position, and the table body 4 is attached to the chair. When rotating in a predetermined direction (clockwise in FIG. 6A) that moves forward, the table body 4 functions as a cam as the table bearing 3 rotates around the storage shaft 7, and corresponds to a follower. The table body 4 is slidably brought into contact with the back surface of the table at the edge, and the table body 4 is raised from the use posture around the pin 6 (around the second axis), and the table body 4 is attached to the table bearing 3 as shown in FIG. It is rotated to a storage posture that extends in parallel (that is, the surface of the table body 4 extends parallel to a virtual vertical plane extending in the front-rear direction of the chair).

  In general, in order to reduce resistance when the table bearing 3 rotates along the side surface of the table receiver 2 and to prevent scratching, a washer made of plastic or the like is provided between them. In the pivot storage table 1 for a chair, the side surface of the table receiver 2 is covered with a guide portion 5c having a larger area than the washer, and generally a plastic part or an angle adjustment part for another table receiver is provided. The upper surface, the front surface, and the lower surface of the table receiver 2 are also covered with the table body support portion 5a and the table body posture control portion 5b integrated with the guide portion 5c.

  Furthermore, it is generally expected that the table in the middle of storage is lowered straight due to its own weight, but the sliding contact member 5 is provided with the guide portion 5c that covers the side portion of the table receiver 2 as described above. By providing it, the posture of the table body 4 is always adjusted so that the table body 4 does not fall down on the seat occupant side, and the table body 4 and the table receiver 2 are directly rubbed and damaged. The sound is not emitted. The guide portion 5c is provided with two screw holes through which the storage shaft 7 and the stopper fixing screw 10 are inserted. Thus, since the table main body support portion 5a, the table main body posture control portion 5b, and the guide portion 5c are integrally formed, the relative dimensional accuracy at the time of use and storage of the table can be increased. The angle adjusting device 4 can be dispensed with. In addition, by molding with a mold such as injection molding, it is possible to improve dimensional stability and reduce the number of parts, thereby reducing part cost and assembly cost.

  Further, in the pivotable retractable table 1 of this embodiment, the stopper 9 made of, for example, plastic is provided in order to avoid unnecessarily pivoting the table body 4 around the storage shaft 7. The stopper 9 may be integrally formed with the sliding contact member 5 or may be integrally formed with the table receiver 2. However, in order to be able to be replaced when damage due to repeated use occurs, the stopper 9 is used here. The stopper fixing screw 10 is fastened to the second screw hole 2c. As shown in FIG. 8, the stopper 9 lowers the table body 4 to the storage position so as not to rotate further when the table body 4 is raised upward and as shown in FIG. 7. At the same time, it has a function to push it deeper and hit the chair body to prevent damage.

  FIGS. 9A, 9B, and 9C show an application example in which the pivotable storage table 1 for a chair according to this embodiment is attached to, for example, a three-seat connection chair in a state where the table body is in the use position. FIG. 10 (a), FIG. 10 (b) and FIG. 10 (c) are front views, plan views and sectional views taken along line EE in FIG. FIG. 11A, FIG. 11B, and FIG. 11C are the front view, the plan view, and the sectional view taken along the line EE in FIG. It is the front view which shows the same application example in the state which the table main body got down to the storage position under the table receptacle, a top view, and sectional drawing which follows the EE line in (a).

  In this application example, the rotary storage table 1 for a chair according to the above embodiment is mounted as a table unit on each chair of a standing chair type three-seat connecting chair 12 used for a viewing seat, etc. Each of the connecting chairs 12 includes a back 12a, a seat 12b, elbows 12c located on the left and right sides of the seat 12b, and both left and right sides of the seat 12b as a frame for supporting the back 12a, the seat 12b and the elbow 12c. The elbow 12c and the leg 12d between the adjacent chairs on the left and right are common to the adjacent chairs.

  And in this application example, the table receiver 2 of the rotary storage table 1 for a chair of the above embodiment is placed on the side surface facing the seat 12b of the front upper end of the leg 12d located on the right side of each chair. It is fixed with three bolts through the bolt holes 2a.

  In the rotating and storing table 1 for a chair of this embodiment in this application example, the seat body is stored in a table main body in a storing posture stored below the table receiver 2 positioned on the side of the chair seat 12b. When the table bearing 3 is rotated around the storage shaft 7 and positioned at a predetermined rotational position where the pin 6 is horizontal by rotating it forward and holding it 4, as shown in FIG. The table body support portion 5 a of the sliding contact member 5 provided on the receiver 2 rotates to the use posture around the pins 6 of the table body 4 without interfering with the table body 4 only at the rotation position of the table bearing 3. The back surface of the table body 4 that is allowed and rotated to its use posture is supported, and the table body 4 is maintained in a use state in which the surface is horizontal.

  In addition, when the seated person pushes the table body 4 in the use posture and in the use state forward, the table bearing 3 is moved around the storage shaft 7 from the predetermined rotation position to the front of the chair. When the table bearing 3 is rotated, the table body posture control unit 5b of the sliding contact member 5 provided on the table receiver 2 functions like a cam as the table bearing 3 rotates around the storage shaft 7, and corresponds to a follower. The table body 4 is slidably brought into contact with the back surface of the table body 4, and the table body 4 is raised from the use posture around the pin 6 and rotated to the stowed posture, whereby the table body 4 extends in a vertical plane (virtual plane) extending in the longitudinal direction of the chair. ), The table holder 3 is rotated forward together with the table bearing 3 by its own weight, and further rotated downward, as shown in FIG. 11, the table holder located on the side of the chair seat 12b. It is housed in 2 below. As shown in FIG. 10, even if the seated person first raises the table body 4 around the pin 6 from the use posture and rotates the table body 4 to the storage posture, the table body 4 can be pushed forward. Is rotated forward together with the table bearing 3 by its own weight in the same manner as described above, and further rotated downward, and is stored below the table receiver 2 located on the side of the chair seat 12b as shown in FIG. The

  Therefore, according to the rotating and storing table 1 for a chair of this embodiment, the table body 4 can be put in a use state positioned in front of the seated person when the table is used, and when the table is not used or when a person passes. Is a rotary storage table that can store the table main body 4 below the table receiver 2 located on the side of the chair seat 12b, and is mainly composed of three parts: the table receiver 2, the table bearing 3, and the table main body 4. Therefore, the rotary storage structure of the table can be made simple and compact, the cost can be reduced, and the appearance can be made beautiful without being complicated.

  In addition, according to the pivotable retractable table 1 of this embodiment, the table main body support portion 5a and the table main body posture control portion 5b are fitted to the table receiver 2 so that the table receiver 2 and the table bearing 3 Since it is formed by the sliding contact member 5 that is a plastic member extending to the gap, the table body 4 as the movable portion can be prevented from being damaged, and the sliding contact member 5 that is a plastic member is smooth. The warm feeling can make the user feel comfortable and, in addition, the number of parts is reduced and the cost is reduced compared to the case where the table main body support portion 5a and the table main body posture control portion 5b are manufactured by separate members. Furthermore, the stable contact member 5 which is a plastic member is molded to increase its dimensional stability, and the table body 4 after the table is assembled. It is also possible to eliminate the need for adjustments such as leveling in use.

  In addition, according to the chair pivotable storage table 1 of this embodiment, in the state where the table body 4 is in use, the front end near the other end opposite to the hinge 4b is the hinge 4b. The table body 4 is shaped like a substantially parallelogram so that the rear end near the other end is retracted forward from the rear end near the hinge portion 4b while projecting forward from the front end near the front. Therefore, the table body 4 is easy to use because it is located in front of the seated person and away from the seated person in the used state, and is rotated about 180 degrees around the storage shaft 7 in the housed state. The front end near the other end opposite to 4b protrudes rearward from the front end near the hinge 4b, while the rear end near the other end is the rear end near the hinge 4b. Because it retracts to the back rather than the part, the chair front So as not to interfere with the human toll, the table body 4 can be retracted larger.

  Further, according to the pivotable retractable table 1 of this embodiment, the table bearing 3 is in contact with the table main body 4 and is on the side opposite to the use posture exceeding the storage posture around the pins 6 of the table main body 4. Since it has the corner | angular part 3d which controls rotation to the side, it can prevent with a simple structure that the table main body 4 falls down to the adjacent chair side.

  Further, according to the pivotable retractable table 1 of this embodiment, the table receiver 3 is in contact with the table body 4 or the table bearing 3 and has the predetermined direction exceeding the predetermined rotation position of the table bearing 3. Since the stopper 9 that restricts the rotation in the opposite direction and restricts the rotation of the table bearing 3 in the predetermined direction within the predetermined limit is provided, the table body 4 and the table bearing can be configured with a simple configuration. The excessive rotation around the three storage shafts 7 can be restrained.

  And, according to the pivotable retractable table 1 of this embodiment, as shown in the figure, the table unit in the retracted state can be set narrower than the width of the elbow 12c, so that the basic chair back 12a and seat 12b can be set. Since it is not necessary to narrow the width or to be biased to the opposite side of the table unit, it is possible to maintain the performance of the chair without impairing the sitting comfort.

  Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described embodiments, and can be appropriately changed within the scope of the claims. For example, the table body support portion 5a and at least one of the table body posture control unit 5b may be formed integrally with the table receiver 2, and the table receiver 2 is formed in a U shape when viewed from above, and the side supporting the support shaft of the table bearing is provided. The table main body support section and the side on which the table main body posture control section is provided may be divided into left and right. Furthermore, although the table plate 4a has a substantially parallelogram shape in the above example, it may have another shape, for example, a trapezoidal shape as long as it is asymmetrically offset with respect to the table bearing 3. And when applying the rotation storing type table for chairs of this invention to a chair, you may fix a table holder to fixed parts other than a leg, such as the back of a chair, and the rotation storage for chairs of this invention. The formula table may be configured symmetrically with the above embodiment, and the table holder may be disposed on the left side of the chair seat and fixed to the chair.

  Thus, according to the pivotable retractable table for the chair of the present invention, the table body can be placed in front of the seated person when the table is used, and the table body can be used when the table is not used or when a person passes. Since the rotary storage type table that can be stored under the table receiver located on the side of the chair seat can be mainly composed of three parts: a table receiver, a table bearing, and a table body, the table can be rotated. The storage structure can be made simple and compact, the cost can be reduced, and the appearance can be made beautiful.
