Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a partition device that partitions a room, and more specifically, partitions a room by running a plurality of partition panels along a rail, and connects each partition panel to one end of the rail. The present invention relates to a partitioning device that releases the partitioning state by rotating the side so that it is substantially perpendicular to the rails, and more specifically, it allows the partitioning panel to run stably with respect to the rails without rattling, and also to effectively use such a configuration. This technology relates to a technology that can be used to stably rotate partition panels to open and close them.

[Background Art] Conventionally, in a partition device, a runner provided on the partition panel side with respect to a rail is mounted so as to be freely movable, and the partition panel is configured to be horizontally rotatable with respect to a vertical axis having the runner.
A configuration in which a plurality of partition panels are run along a rail to create a partition, and each of these partition panels is rotated at one end of the rail so as to be substantially perpendicular to the rail to release the partition state. It was hot. However, with this configuration, when the partition panel is run along the rail, the necessary clearance between the runner and the rail causes rattling, making it impossible to run smoothly. Moreover, there was a problem in that the partition panel rattled when it was rotated to open and close.

[Purpose of the invention] The present invention was made in view of these problems, and its purpose is to provide a partition device that can eliminate rattling during running and rotation.

[Disclosure of the invention] The present invention is a partitioning device in which a plurality of partition panels are configured to be able to run freely along an upper rail 1 and a lower rail 2 and to be able to open and rotate approximately perpendicularly to the upper and lower rails 1 and 2. A rack gear 3 is provided on one vertical wall of the upper rail 1 and the lower rail 2 over the entire length of the rail, and a pinion gear 5 is provided on the upper and lower ends of the partition panel 4 so as to be horizontally rotatable approximately coaxially. A partition characterized in that a pinion gear 5 is meshed with a rack gear 3, and a running guide 62 is provided on either the upper or lower side of the other end of the partition panel 4 so as to be able to run on either the upper or lower rail and can be protruded and retracted. The invention relates to an apparatus, and by configuring it in this way, the above object can be achieved. In other words, by meshing rack gears and pinion gears at the top and bottom of one end of the partition panel, and making the travel guide along the other end freely travelable on the rail, the amount of travel on the top and bottom parts of the partition panel is made equal. It can run along the rail without causing any rattling, and it can be rotated by rotating the partition panel while engaging the rack gear and pinion gear in the upper and lower positions with the running guide retracted. This is to eliminate wobbling.

Embodiments of the present invention will be described in detail below based on the drawings.

A plurality of partition panels 4 are built so as to be freely movable between an upper rail 1 fixed to a lintel and a lower rail 2 fixed to a sill. These partition panels 4 have upper and lower rails 1,
2 in a straight line, and by bringing adjacent ones into contact with each other, the opening in the room can be closed and partitioned. In such a closed state, the locking means provided in the upper and lower portions of one side of the partition panel 4 locks the movement of the partition panel 4, fixes the position of each partition panel 4, and secures the partition panel 4. It is made so that it cannot be opened. To open the partition panel 4 and release the partition, operate the lock handle 6 of the partition panel 4 at the right end in FIG. The partition panel 4 at the right end is rotated around its right end portion so as to be approximately perpendicular to the upper and lower rails 1 and 2 to open it, and then the remaining partition panel 4 is moved slightly within the range of its locked state. By releasing the contact between the partition panels 4, the locked state of the remaining partition panels 4 is automatically released, and then as shown in FIG. 3, the right end portion of each of the remaining partition panels 4 is released. It is rotated around the center to create a non-partitioned state. The partition panel 4 thus rotated into a non-partitioning state is gathered at the left end of the upper and lower rails 1 and 2, so that the opening in the room can be opened wide and the partition can be released.

The configuration for performing the above operations will be described in detail below.

As shown in FIG. 5, the upper rail 1 is divided into a rack and pinion chamber 7 extending over its entire length and a runner chamber 8 below this, while the lower rail 2 has only the rack and pinion chamber 7 as shown in FIG. It is formed to the full length. A rack holding piece 9 is provided along the entire length of one vertical wall of each rack and pinion chamber 7. As shown in FIGS. 7 to 9, the rack gear 3 is considerably shorter in length than the upper and lower rails 1 and 2. A connecting protrusion 11 is formed at one end in the length direction of the rack gear 3, and a connecting recess 12 is formed at the other end. Furthermore, an engagement groove 10 is formed in the rack gear 3 over its entire length. Thus, by engaging the engagement groove 10 with the rack holding piece 9 and connecting the connecting protrusion 11 with the connecting recess 12, the rack gear is inserted along the vertical wall on one side of the rack and pinion chamber 7 of the upper and lower rails 1 and 2. 3 is provided over the entire length of the upper and lower rails 1 and 2.

Rack gears 3 provided in the rack and pinion chambers 7 of the upper and lower rails 1 and 2 mesh with pinion gears 5 provided on the partition panel 4 side so as to be horizontally rotatable, and also on the partition panel 4 side so as to be freely rotatable up and down about a horizontal axis. A runner 13 provided in the runner chamber 8 of the upper rail 1 is rotatably mounted on the runner receiving surface 14 of the runner chamber 8 of the upper rail 1, and when the partition panel 4 runs, the pinion gear 5 meshes with the rack gear 3. The runner 13 is configured to roll on the runner receiving surface 14 while maintaining the engaged state. In this way, the pinion gear 5 is connected to the rack gear 3.
By making the partition panel 4 travel while meshing with each other, the travel amount of the upper and lower parts of the partition panel 4 is made equal, so that the partition panel 4 can travel without wobbling. In such case,
The load of the partition panel 4 is not applied to the meshing portion between the rack gear 3 and the pinion gear 5, so that no force is applied to the meshing state. The configuration will be explained below.

The roller-shaped runner 13 is rotatably inserted into the horizontal shaft 32, and is prevented from coming off with an E ring 24. A male thread 33 is formed on the lower outer surface of the outer shaft 28. The runner section 21 is connected to the runner holding block 15 by screwing the external thread 33 of the outer shaft 28 into the threaded hole 19 of the cylindrical section 20 of the runner holding block 15. The pinion shaft 22 is rotatably inserted through the vertical hole 34 of the holding block 29 and the cylindrical outer shaft 28. In such a case, the outer race of the bearing 23 on the pinion shaft 22 side is fitted into the recess 35 of the holding block 29, so that the pinion shaft 22 can rotate smoothly, and the pinion meshing with the rack gear 3 The gear 5 is designed to mesh and rotate smoothly.

According to such a configuration, the runner part 21 is screwed to the runner holding block 15 connected to the partition panel 4 side, and the runner 13 which is rotatable to the runner part 21 is mounted on the runner receiving surface 14 of the upper rail 1. The load of the partition panel 4 can be received by the upper rail 1, and the load of the partition panel 4 is not applied to the pinion gear 5 side, so that the meshing state between the pinion gear 5 and the rack gear 3 is not forced. It doesn't cost anything.

18 to 21 show the pivot receiver 36, in which a mounting hole 39 is provided in the lower horizontal piece 38 of the L-shaped receiver body 37. A cylindrical portion 42 in which an insertion hole 41 is formed is formed at the lower end of the vertical piece 40 of the receiving body 37 . Therefore, the pivot receiver 36 is placed in the 24th position.
As shown in the figure, it is attached to the lower corner of one end of the partition panel 4 with screws. A pinion gear 5 is rotatably attached to the lower end of the pinion shaft 22, and a slider 43 for the lower rail 2 is rotatably provided above the pinion gear 5. This slider 43 has a miniature bearing 4.
4 is provided to reduce the sliding resistance with the lower rail 2. The pinion shaft 22 is rotatably inserted into the insertion hole 41 of the cylindrical portion 42 of the pivot receiver 36, and the pinion gear 5 is also meshed with the rack gear 3 at the lower part. A spring 46 is interposed between the flange portion 45 and the cylindrical portion 42 of the pinion shaft 22 to prevent the pinion shaft 22 from descending under its own weight and increasing sliding resistance with the lower rail 2. I have made sure that there is no such thing.

The pinion shaft 22 is divided into three parts. In other words, it is divided into three parts: an upper pinion shaft 22a rotatably supported by the runner part 21, a lower pinion shaft 22c rotatably supported by the pivot receiver 36, and an intermediate pinion shaft 22b connecting these. be. The upper pinion shaft 22a and the intermediate pinion shaft 22b are connected as shown in FIGS. 25 to 27. That is, the lower end of the upper pinion shaft 22a and the upper end of the lower pinion shaft 22c are each chamfered into a half-moon shape. These chamfered portions 47 are connected to the upper joint 48.
They are each slidably inserted into a half-moon-shaped hole 49 formed therethrough. As shown in FIGS. 28 to 29, this upper joint 48 is attached to a C-shaped holding portion 50.
It is held rotatably but immovably up and down by an upper retainer 51 formed with a. This upper presser 51 is attached to the side end surface of the partition panel 4 with screws. The middle portion of the intermediate pinion shaft 22b is also chamfered in a half-moon shape, and this chamfered portion 47 is inserted non-rotatably into the circular hole 61 of the holder 52 as shown in FIG. 51, it is held rotatably but immovably up and down. The lower end of the intermediate pinion shaft 22b and the upper end of the lower pinion shaft 22c are each chamfered into a semicircular shape to form an intermediate partition 53 and a semicircular hole 49, as shown in FIGS. 35 to 37. Each chamfered portion 47 is inserted non-rotatably into the semicircular hole 49 of the lower joint 54, and the lower joint 54 is inserted into the 38th hole.
As shown in FIGS. 40 to 40, a C-shaped holding part 50
As shown in FIGS. 41 to 43, it is held rotatably but immovably vertically by lower presses 55 formed on top and bottom. In this way, the upper, middle, and lower pinion shafts 22a, 22b, and 22c are connected so that they can slide vertically and rotate together. In this way, the three pinion shafts 22a, 22
By configuring b and 22c to be integrally rotatable, the upper and lower pinion gears 5 can be rotated at a constant speed, and the partition panel 4 can run more smoothly.

In order to provide the partition panel 4 with the runner portion 21 having the pinion gear 5 described above and the pivot receiver 36, as shown in FIG.
A mounting recess 56 is provided at one end over the entire vertical length, and the runner portion 21, pivot receiver 36, and pinion shaft 22 are inserted and mounted into this mounting recess 56. Then, the joint cover 58 is inserted and locked from the vertical direction into the grooves 57 formed in the runner holding block 15, the pivot receiver 36, the upper presser 51, and the lower presser 55, respectively, and the joint cover 58 is inserted into the mounting recess 5.
6 and the various members inserted therein. The joint cover 58 is provided with an elastic cushion material 59. A connection recess 60 is formed at the other end of the partition panel 4.
By inserting the elastic cushion material 59 of the adjacent partition panel 4 into the partition panel 0, the partition panels 4 are connected without a gap to prevent light from leaking or wind from entering in the partitioned state. In this partition state where adjacent partition panels 4 are in contact with each other, the operating handles ( (not shown) are pushed in, and locking means in the form of penetrations protrude from the upper and lower ends of the partition panel 4, respectively, to position the partition panel 4. Then, in a state in which the partition panels 4 are in a movable state in which the abutment between the partition panels 4 is released and each locking means is released, the partition panels 4 are opened and rotated using the pinion shaft 22 as the rotation axis. The partitions are removed as shown in Figure 3.

As shown in FIGS. 45 to 47, on the side of the partition panel 4 opposite to the side on which running tools such as the runners 13 and sliders 43 are provided, guide tubes 69 are provided from the upper and lower ends. On the other hand, a traveling guide 62 is provided so as to be able to protrude and retire. These travel guides 62 are designed to fit into grooves 63 of the upper and lower rails 1 and 2. An operating tool 6 for protruding and retiring the travel guide 62 is provided on the side end surface of the partition panel 4.
7 is provided so as to be slidable up and down with respect to a slide guide 70. A pair of rotary disks 72 are rotatably mounted on the partition panel 4 via a rack and pinion mechanism 71 by vertically sliding the operating tool 67 . The traveling guide 62 is connected to these rotary discs 72 via bent links 73 so as to be able to protrude and retract as it rotates. In other words, when you put your finger on the recessed part 74 of the traveling tool 67 and pull up the operating tool 67, the pair of rotary discs 72 are meshed and rotated via the rack and pinion mechanism 71, and the traveling tool 67 moves through the bent link 73. The guide 62 is designed to be able to protrude from the upper and lower ends of the partition panel 4. Furthermore, the traveling guide 62 can be retired by pulling down the operating tool 67. By retiring the traveling guide 62 in this manner, the partition panel 4 can be opened and rotated.

Note that the design of the traveling guide 62 and its operating means can be changed in various ways.

[Effects of the invention] In summary, the present invention provides a pinion gear at one end of the upper and lower sides of the partition panel so as to be horizontally rotatable approximately coaxially, and meshes the pinion gear with the rack gear. Since a travel guide that can freely travel on either the upper or lower rail is provided in a protruding and retractable manner, in other words, by meshing the rack gear and the pinion gear in the upper and lower parts, the travel distance of the upper and lower parts of the partition panel is made equal. In combination with the guide running by the travel guide, it is possible to run smoothly without causing any rattling, and the rack and pinion is effective for smooth travel. In other words, by retiring the traveling guide and rotating the partition panel with the rack gear and pinion gear engaged at the top and bottom, it is possible to eliminate rattling during rotation and achieve smooth rotation. It has the advantage that the panels can be opened and closed smoothly, and that it is easy to overlap multiple partition panels to eliminate room partitions and make the room larger. In this way, it is possible to run the partition panel stably even when the partition panel is opened almost perpendicular to the upper and lower rails, and there is an advantage that it is possible to stably perform a retraction operation that allows multiple partition panels to run with them open. .
