Description

Rotationally retractable table for chair}

The present invention relates to a rotating storage table for chairs such as grandstands.

In a grandstand provided in a theater, a stadium, etc., a small table for writing and eating may be added.

Some seats have a back and a seat, and some have a back and a seat. In addition, the seats are up and out of the way when others pass by. But in any chair, the basic situation is that of a person sitting. Therefore, in the case of adding a table, in order to arrange the table in a range where a hand does not touch a person's stomach naturally, the table is placed in a position approximately horizontal to the front of the seat of the seat at a height close to that of the elbow. (See, for example, Japanese Patent Application Laid-Open No. 2003-79480).

However, the grandstand is usually arranged in rows with multiple seats connected to the left and right, and several rows are installed in a row in front and back, so that if the table is fixed in use, the table will be disturbed when a person passes between rows and columns. It becomes.

Therefore, as described in Patent Literature 1, it is common to set the structure so that the passage is widened and stored in the lower part of the seat so as not to disturb the movement of the person when the seat is seated. However, the conventional rotational storage structure is complicated and large-scale, which leads to high cost and complicated appearance. Moreover, there existed a problem that a movable part was easy to be damaged, and the usability of a seated person was also not necessarily desirable.

Therefore, an object of the present invention is to reduce the cost by keeping the table rotating storage structure simple and compact, to keep the appearance beautiful, to prevent the movable part from being damaged, and to make the seated user feel comfortable. Doing.

This invention is made | formed in order to solve the said subject advantageously, The chair seat | seat revolving type table of this invention is a table stand which is fixed to a chair, and located in the side of the chair seat, and the said table stand, of the said chair. On the first axis, around the table bearing pivotally pivoted around the first axis extending in the left and right directions, and around the second axis extending parallel to the vertical plane extending in the front-rear direction of the chair. A pivoting table for chairs having a table body pivotably pivoted between a use posture extending in parallel and a storage posture extending in parallel to the vertical plane, wherein the table rest is a table main body support and a table. A main body posture control unit, said table main body supporting unit having said table bearing two said first axes Allows rotation to the use posture around the second axis of the table main body only in a state of being positioned at a predetermined rotational position of the table main body, supports the back surface of the table main body in the use posture, and uses the table main body in a use state. The table main body attitude control unit is arranged on the rear surface of the table main body when the table bearing rotates from the predetermined rotational position around the first axis in a predetermined direction in which the table main body moves forward of the chair. Sliding contact is made, and the table main body is rotated to the said storage attitude | position, raising from the said use attitude | position around the said 2nd axis line.

In such a chair-type revolving table, the seat bearing is lifted upward by turning the table main body of the storage posture stored in the lower part of the table seat positioned on the side of the chair seat to the front to raise the table bearing around the first axis. In a predetermined rotational position where, for example, the second axis is horizontal, the table main body support portion of the table support does not interfere with the table main body only at the rotational position of the table bearing, The rotation to the use posture is allowed, the back surface of the table body rotated to the use posture is supported, and the table main body is maintained in a use state where the surface is horizontal, for example.

Moreover, when the seat body pushes forward the table main body which is also in the use posture also in the use state, and rotates a table bearing to the front direction of a chair from the said predetermined rotation position around a 1st axis line, As the bearing rotates around the first axis, the table body posture control portion of the table receiver functions like a cam, sliding contact with the back surface of the table body corresponding to the follower, and the table body about the second axis from the use posture. The table body is in a state parallel to the vertical plane (virtual plane) extending in the front and rear direction of the chair, and rotates forward with the table bearing forward by its own weight, further down It rotates and is stored under the table base which is located to the side of a chair seat.

Therefore, according to the revolving storage type table for chairs of the present invention, the table main body can be brought into the use state positioned in front of the seated person when the table is in use, and the table main body is used when the table is not used or when a person passes. The rotating storage table that can be stored under the table seat located on the side can be mainly composed of three parts of the table support, the table bearing, and the table body, making the rotating storage structure of the table simple and compact. It can save cost and can make the appearance beautiful without being troublesome.

Moreover, in the rotating storage table for chairs of this invention, the said table main body support part and the said table main body attitude control part are made of the plastic member which fits in the said table base and extends between the table base and the said table bearing. It may be formed. By doing in this way, the table main body as a movable part can be prevented from being damaged, and the usability of a seated person can be made comfortable by the smooth and warm texture of a plastic member. Furthermore, compared to the case where the table main body support and the table main body post control are made of separate members, the number of parts can be reduced and the cost can be reduced. Furthermore, by molding the plastic member, the dimensional stability is increased, and the table Adjustment such as horizontal leveling in the use state of the table main body after assembly may be unnecessary.

Moreover, in the rotating storage table for chairs of this invention, the said table main body is a front end part on the other end side opposite to the one end pivoted to the said table bearing in the said use state to the front end part near the said one end part in the said use state. While protruding, the rear end of the other end may enter the front of the rear end near the one end. In this way, the table main body is convenient to use because it is located away from the seated person in front of the seated person in the use state, and in the stored state, the table main body is rotated about 180 degrees around the first axis and pivoted to the table bearing. The front end of the other end on the opposite side protrudes rearward from the front end of the vicinity of the one end, while the rear end of the other end enters behind the rear end near the one end, thus obstructing the passage of the person in front of the chair. It can be made larger so that it does not become.

Furthermore, in the rotating storage table for chairs of the present invention, the table bearing is in contact with the table main body and restricts the rotation to the side opposite to the use posture beyond the storing posture around the second axis of the table main body. You may have a table body stopper. In this way, the table main body can be prevented from falling over on the adjacent chair side.

And in the rotation storage type table for chairs of this invention, the said table base contact | connects the said table main body or the said table bearing, and rotates to the opposite direction to the said predetermined direction beyond the said predetermined rotational position of the table bearing. In addition to the regulation, the table bearing stopper may be configured to regulate the rotation of the table bearing in the predetermined direction within a predetermined limit. By doing in this way, excessive rotation about the 1st axis line of a table main body and a table bearing can be suppressed with a simple and easy structure.

It is sectional drawing along A line. 7 (a) and 7 (b) are side views showing a state in which the table main body of the rotating storage table for chairs of the embodiment is rotated at a lower storage position around the first axis along with the table bearing and A in (a) thereof; It is sectional drawing along the -A line. FIG. 8 is a side view showing a state where the table main body of the rotating storage table for chairs of the embodiment attempts to rotate to the rear of the chair around the first axis along with the table bearing and is restricted by the stopper. In the figure, reference numeral 1 denotes a pivoting table for chairs of the embodiment, 2 a table support, 3 a table bearing, and 4 a table body, respectively.

As shown in Figs. 9 to 11, which will be described later, the pivoting table 1 for a chair of the present embodiment is used as a table unit, for example, as a seating type connecting chair 12 used in a grandstand or the like. As shown in FIGS. 1-5, the main part is equipped with the table base 2, the table bearing 3, and the table main body 4, The table base 2 is a sliding contact member. (5) is attached.

Although the table main body 4 may be comprised from the board plate of a wood or a plastic, and the hardware component which supports it, Preferably, the table main body 4 is a molded article which unites the table board 4a and the hinge part 4b. This can reduce the cost. And productivity can also be largely improved by using aluminum alloy die-casting and reinforced plastic injection molded articles. The hinge part 4b located in the one end part of the side of the table main body 4 is provided with the through-hole 4c parallel to the surface of the table board 4a.

Here, in the use state shown in FIG.1 (c) and FIG. 9 mentioned later, the table board 4a is the front end part of the front end of the hinge part 4b near the other end part on the opposite side to the hinge part 4b. It protrudes more forward and forms a substantially parallelogram shape so that the rear end of the other end side may go forward than the rear end near the hinge portion 4b.

The table bearing 3 becomes a support part when the table main body 4 is rotated and accommodated. As shown in FIG. 5, the through-hole 3b extended in the left-right direction (in FIG. 5 (a)) of the hinge part 3a pinched | interposed between the two hinge parts 4b of the table main body 4, and FIG. And a shaft hole 3c extending in a direction perpendicular to the paper surface under the hinge portion 3a (in FIG. 5 (a)), and penetrating the hinge portion 3a of the table bearing 3. The table main body 4 is rotatably assembled by aligning the through hole 4c of the hole 3b and the hinge part 4b of the table main body 4, and inserting the pin 6 in it. In the illustrated example, the table bearing 3 and the table main body 4 are inserted by inserting two pins 6 from both sides of the table main body 4 so as to pass through the table bearing 3 and the table main body 4. ) Is easy to assemble, but the assembly may be performed using one pin 6 penetrating the table bearing 3 and the table main body 4. The center axis of these through holes 3b and 4c becomes the second axis. Moreover, the table bearing 3 is assembled to the table base 2 so that rotation is possible by tightening and attaching the storage shaft 7 which was inserted in the shaft hole 3c to the table base 2. The center axis of this shaft hole 3c becomes a 1st axis line.

Here, 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 (right side in Fig. 5 (a)) when positioned above the shaft hole 3c. Thereby, when the table bearing 3 rotates 180 degrees from the attitude | position of FIG. 5 (a), ie, when the hinge part 3a is located downward with respect to the axial hole 3c, the hinge part 3a ) Is offset from the symmetrical position with respect to the shaft hole 3c to the rear of the chair, and the table main body 4 is compactly stored. In addition, the cross-sectional shape of the hinge part 3a is a side facing the table base 2 as shown to FIG. 1 (b)-(d), but the side facing the opposite side to the table base 2 is The parts 3d are left. As a result, as shown in Fig. 1 (d), even if the table main body 4 is about to fall from the storage posture to the side opposite to the use posture side, the respective hinge portions 3d are two hinge portions of the table main body 4. It touches the part between (4b) and functions as a table main body stopper which prevents the table main body 4 from falling. Furthermore, in order to give a moderate resistance to the rotation of the table main body 4 with respect to the table bearing 3, the spring 6 is preferably used for the pin 6. In addition, the table body 4 is smoothly rotated and wear is preferably interposed between the table body 4 and the pin 6 so as to reduce wear.

The table holder 2 is bolted to a chair to support the table bearing 3 so as to be rotatable. In addition to the three bolt holes 2a, a screw hole with a female screw for fastening and attaching the storage shaft 7 is provided. (2b) and the screw hole 2c in which the female screw for tightening the stopper fixing screw 10 for fixing the stopper 9 mentioned later is formed. When the storage shaft 7 is tightened to the screw hole 2b of the table support 2, the table bearing 3 and the storage shaft 7 are preferably rotated smoothly and less wear is applied. A plastic bush 11 is interposed between them.

As shown in Figs. 1A and 4, the sliding contact member 5 includes a table main body support part 5a which is a horizontal plane in the upward direction in this embodiment, and a table main body support part in this embodiment ( It is always larger than the distance D1 between the horizontal plane of 5a) and the center axis of the storage shaft 7 but from the center axis by a distance D2 that varies with the angle from the vertical line of the straight line connecting the center axis and the target position. Sliding contact with the table body attitude | position control part 5b and the table bearing 3 and the table main body 4 which are the convexly curved surfaces which move away, and smoothly line up on the said horizontal plane, and a direction changes from an upward direction to an oblique downward direction from an upward direction. To form a guide part 5c, which is a side surface for guiding such rotation around the storage shaft 7, on the table support 2, and is formed of a plastic integrally formed cap. The sliding contact member 5 is tightly fitted to the table support 2 and is fixed to the table support 2 with the stopper fixing screw 10 together with the stopper 9, and at the same time the table is also supported by the table bearing 3 It is pressed and fixed to the receiving part 2.

Here, as shown in FIG. 1 (a), the table main body support part 5a has the through-holes 3b and 4c and the pin (in which the table bearing 3 is the periphery of the storage shaft 7 (1st axis periphery)). Only in the state where the center axis line of 6) is located in the predetermined rotational position which becomes horizontal to the upper side of the storage shaft 7, as shown in FIG.1 (c), the pin 6 does not interfere with the table main body 4, ) Use posture of the table body 4 of the perimeter (circumference of the 2nd axis) bent at a right angle with respect to the table bearing 3 here (that is, the surface of the table body 4 extends parallel to the first axis). While allowing up to rotation, the back surface of the table main body 4 in its use posture is supported, and the table main body 4 is used in such a state that the surface of the table main body 4 is horizontal.

Here, as shown in FIG. 6 (a), the table main body attitude control part 5b has the table main body (3) with the table main body (3) from the predetermined rotational position on the periphery of the storage shaft 7 (first axis line circumference). When 4) rotates in a predetermined direction (clockwise in FIG. 6 (a)) moving to the front of the chair, the table bearing 3 functions like a cam as it rotates around the storage shaft 7 and acts as a follower. The back surface of the corresponding table main body 4 is slid-contacted by the edge part, raises the table main body 4 to the circumference | surroundings of the pin 6 (2nd axis circumference) from the said use posture, and is shown in FIG. 6 (b). Similarly, the table body 4 is rotated to a storage posture extending parallel to the table bearing 3 (that is, the surface of the table body 4 extends parallel to a virtual vertical plane extending in the front and rear direction of the chair). Let's do it.

In general, in order to reduce the resistance when the table bearing 3 rotates along the side surface of the table support 2 and to prevent damage, a washer made of plastic or the like is provided therebetween. In the rotating storage table 1, the side surface of the table base 2 is covered with a guide portion 5c having an area larger than that of the washer, and in general, plastic parts and angle adjusting parts for other table bases are provided. Then, the upper surface, the front surface, and the lower side of the table base 2 are wrapped with the table main body support 5a and the table main body attitude control unit 5b integrated with the guide portion 5c.

In addition, generally, the table during storage is expected to fall straight down by its own weight. However, the sliding contact member 5 is provided with a guide portion 5c that largely surrounds the side of the table support 2 as described above. The posture of the table main body 4 is always trimmed, the table main body 4 does not fall to the seat side of a chair, and the table main body 4 and the table base 2 directly contact and are damaged. Do not make a joint sound. In addition, the guide part 5c is provided with two screw holes which respectively fit the storage shaft 7 and the stopper fixing screw 10. As shown in FIG. Thus, by using the table main body support part 5a, the table main body attitude control part 5b, and the guide part 5c as an integral molded article, the relation dimension precision at the time of use and storage of a table can be improved, and therefore, the table main body 4 Angle adjusting device and the like can be made unnecessary. In addition, by molding with a mold such as injection molding, the dimensional stability can be increased, and the number of parts can be reduced, thereby reducing the parts cost and the assembly cost.

In addition, in the rotating storage table 1 for chairs of the present embodiment, in order to avoid unnecessarily large rotation of the table main body 4 around the storage shaft 7, the stopper 9 made of, for example, plastic Prepare. The stopper 9 may be integrally formed on the sliding contact member 5 or integrally molded on the table support 2, but in order to be replaceable in the case of damage caused by repeated use, the table is used here. Tighten with a stopper fixing screw 10 to the screw hole 2c of the base 2. As shown in FIG. 8, the stopper 9 stores a function for preventing the table body 4 from turning backward when the table body 4 is raised upward, and stores the table body 4 as shown in FIG. 7. When it is in position, it has a function to push it inward more and not to be damaged by hitting the chair body.

9 (a), 9 (b) and 9 (c) show a state in which the table main body is in a use position of an application in which the rotating storage table 1 for a chair of the present embodiment is attached to, for example, a three-person connecting chair. The front view shown, the top view, and sectional drawing along the E-E line in (a) are shown, respectively. (A), (b) and (c) are the front view which shows the application example similar to FIG. 9 from the use posture to the storage attitude, the top view, and the E-E line in (a). The cross section which follows is shown, respectively. 11 (a), 11 (b) and 11 (c) are front views, plan views, and E in (a) illustrating a state in which the table body is lowered to the storage position of the lower side of the table support, as in FIG. 9. The cross-sectional view along the -E line is shown, respectively.

In this application example, the chair-swivel-type table 1 of the said embodiment is attached as a table unit to each chair of the three-seat connecting chair 12 of the standing type used for a grandstand. Each chair of the connecting chair 12 in this case is the back 12a, the seat 12b, the elbow 12c located in the left and right sides of the seat 12b, those back 12a, and the seat 12b. ) And plate-shaped legs 12d positioned on both left and right sides of the seat 12b as a frame for supporting the elbow 12c. The elbows 12c and the legs 12d between the chairs adjacent to each other left and right are common to those chairs adjacent to each other.

And in this application example, the side surface of the front side of the upper part of the front part of the leg 12d located in the right side of each chair of the table receiving chair 2 of the rotating storage table 1 for chairs of the said embodiment toward the seat 12b. It is fixed by three bolts through the said bolt hole 2a.

In the rotational storage table 1 for chairs of the present embodiment in the present application, the table body in a storage posture in which a seated person is stored below the table support 2 positioned next to the seat 12b of the chair. When the table bearing 3 is rotated around the storage shaft 7 by turning the upper portion 4 upward, the pin bearing 6 is positioned at a predetermined rotational position where the pin 6 is horizontal, as shown in FIG. 9. The pin body 6 of the table main body 4 does not interfere with the table main body 4 only in the rotational position of the table bearing 3 by the table main body support part 5a of the sliding contact member 5 provided in the table support 2. The back side of the table main body 4 rotated to the use posture is permitted, and the table main body 4 is maintained in the use state which the surface becomes horizontal.

In addition, the seat body pushes the table main body 4 which is also in the use posture in the use state forward, so that the table main body 4 is moved from the predetermined rotational position around the storage shaft 7 to the table main body 4. When it rotates in the direction to move forward, as the table bearing 3 rotates around the storage shaft 7, the table main body attitude control part 5b of the sliding contact member 5 provided in the table base 2 will be like a cam. It functions, and makes sliding contact with the back surface of the table main body 4 corresponded to a follower, and raises the table main body 4 around the pin 6 from a use posture to a storage position. And by this, the table main body 4 will be in the state parallel to the vertical plane (virtual plane) extended in the front-back direction of a chair, and will rotate forward with the table bearing 3 by self weight, and also rotate downward As shown in FIG. 11, it is accommodated below the table base 2 located in the side of the seat 12b of a chair. In addition, as shown in FIG. 10, even if the seat body first raises the table main body 4 from the use posture to the pin 6 circumference and rotates to a storage position, even if the table main body 4 is pushed forward, the table main body (4) rotates forward with the table bearing 3 by self weight as mentioned above, and further rotates downward, and as shown in FIG. 11, the table base located in the side of the seat 12b of a chair ( 2) is stored below.

Therefore, according to the rotating storage table 1 for chairs of this embodiment, when the table is used, the table main body 4 can be brought into the use state positioned in front of the seated person, and when the table is not used or when a person passes through the table. The rotating storage table which can store the table main body 4 in the lower part of the table support 2 located in the side of the seat 12b of a chair is mainly a table support 2, a table bearing 3, and a table. Since it can be comprised with three components with the main body 4, the rotating storage structure of a table can be made simple and compact, cost can be reduced, and it can be made into the beautiful thing which is not complicated in appearance.

Moreover, according to the rotating storage table 1 for chairs of this embodiment, the table main body support part 5a and the table main body attitude control part 5b are fitted to the table base 2, and the table base 2 and the table bearing ( Since it is formed by the sliding contact member 5 which is a plastic member extended to and between 3), the table main body 4 as a movable part can be prevented from being damaged. Along with this, the smooth and warm texture of the sliding contact member 5, which is a plastic member, can improve the comfort of the seated person. Furthermore, the number of parts can be reduced and the cost can be reduced as compared with the case where the table main body support part 5a and the table main body attitude control part 5b are manufactured by separate members. Furthermore, by shaping the sliding contact member 5 which is a plastic member, the dimensional stability can be improved, and adjustment such as horizontal leveling in the use state of the table main body 4 after table assembly can be made unnecessary.

Moreover, according to the rotating storage table 1 for chairs of this embodiment, in the state in which the table main body 4 is in a use state, the front end part of the other end side on the opposite side to the hinge part 4b is the hinge part 4b. The table main body 4 is formed in a substantially parallelogram shape so as to protrude forward from the front end of the vicinity, and the rear end of the other end is moved forward of the rear end of the hinge 4b. From this, the table main body 4 is convenient to use because it is located away from the seated person toward the seated person in the use state. Moreover, in the storage state, the front end portion on the other end side opposite to the hinge portion 4b rotates about 180 degrees around the storage shaft 7 and protrudes rearward from the front end portion near the hinge portion 4b. Since the rear end portion at the end portion enters rearward from the rear end portion near the hinge portion 4b, the table main body 4 can be made larger without disturbing the passage of the person in front of the chair.

Furthermore, according to the rotating storage table 1 for the chair of this embodiment, the table bearing 3 is in contact with the table main body 4 and the use posture beyond the storage posture around the pin 6 of the table main body 4. Since it has the corner | angular part 3d which regulates rotation to the opposite side, it can prevent by the simple and easy structure that the table main body 4 falls over on the adjacent chair side.

Furthermore, according to the rotating storage table 1 for chairs of this embodiment, the table base 2 abuts against the table main body 4 or the table bearing 3 and exceeds the predetermined rotational position of the table bearing 3. In addition to regulating the rotation in the direction opposite to the predetermined direction, and having a stopper 9 for regulating the rotation of the table bearing 3 in the predetermined direction within a predetermined limit, the table main body ( 4) and excessive rotation around the storage shaft 7 of the table bearing 3 can be restrained.

In addition, according to the rotating storage table 1 for a chair of the present embodiment, since it is possible to set a table unit in a state of being narrower than the width of the elbow 12c as shown, the back 12a and the seat of the basic chair. There is no need to narrow (12b) to the side opposite to the table unit. Therefore, the performance of a chair can be maintained without impairing a sense of stability.

As mentioned above, although demonstrated based on the illustration, this invention is not limited to the above-mentioned embodiment, It can change suitably within the description of a claim. For example, at least one of the table main body support part 5a and the table main body attitude control part 5b may be integrally formed in the table base 2. In addition, the table support 2 may be formed in a 'co' shape as viewed from above, and the side for supporting the support shaft of the table bearing and the side for providing the table main body support portion and the table main body posture control portion may be distributed from left to right. In addition, although the table board 4a was made into the shape of substantially parallelogram in the said example, as long as it is a shape which offset asymmetrically with respect to the table bearing 3, you may make it another shape, for example, trapezoid shape. And when applying the rotating storage table for chairs of this invention to a chair, the table base may be fixed to fixed parts other than legs, such as a chair, etc., and also the rotating storage table for chairs of this invention. It may be configured symmetrically with the above embodiment, and the table stand is arranged on the left side of the chair seat and fixed to the chair.

Thus, according to the rotating storage table for chairs of the present invention, the table main body can be brought into the use state positioned in front of the seated person when the table is in use, and the table main body is chaired when the table is not in use or when a person passes. The rotating storage table that can be stored in the lower part of the table support located on the side of the seat can be mainly composed of three parts of the table support, the table bearing, and the table body, making the rotating storage structure of the table simple and compact. The cost can be reduced, and the appearance can be made beautiful without being troublesome.
