Description

  The present invention relates to a partition provided with a sheet material such as a cloth.

Conventionally, as a simple partition placed in an office or a hospital, the upper frame and the lower frame inserted into the bag-like portion formed at the upper end and lower end of the sheet material are held between a pair of left and right columns. Things are known. As an example, a sheet material is stretched between the upper frame and the lower frame by engaging hook portions provided at the end portions of the upper frame and the lower frame with slot holes formed in the support columns. It is done. Specifically, at least one end portion of the upper frame is provided with a hook-like hook portion facing downward, and at least one end portion of the lower frame is provided with an hook-like hook portion facing upward. First, the hook portion of the upper frame is positioned in the vicinity of the upper end portion of the column. In this mode, the sheet material is once pulled downward, and the hook part of the lower frame is engaged with the slot hole provided near the lower end of the column using the tension of the sheet material. (For example, refer nonpatent literature 1).
KOKUYO Office Furniture 2005 Edition, published by KOKUYO Furniture Co., Ltd., December 2004, P.I. Various cross screens shown at the bottom of 223.

  However, the conventional one is a mode in which hook portions are hooked in slot holes formed in the vicinity of the upper end portion and the lower end portion of the support column, so that the mounting height positions of the upper frame and the lower frame with respect to the support column are fixed. . As a result, for example, when sufficient tension cannot be obtained due to the material of the sheet material, or when the height dimension of the sheet material becomes smaller than the separation distance between the upper frame and the lower frame due to sewing error or shrinkage due to washing, etc. If the sheet material is stretched between the upper frame and the lower frame while being forcibly pulled in the height direction, the force of the sheet material will bend in the direction in which the upper frame and the lower frame are brought closer to each other. As a result, the frame may be deformed or damaged.

  The present invention has been made paying attention to such a problem, and its main purpose is to force excessive bending force on the upper frame and the lower frame without being affected by the tension or height of the sheet material. It is an object of the present invention to provide a partition that can prevent the sheet material from acting and can be suitably stretched without loosening the sheet material between the upper frame and the lower frame.

That is, the partition according to the present invention is a partition formed by stretching a sheet material such as a cross between an upper frame and a lower frame disposed between a pair of support columns, and at least the lower frame is provided between the support columns. The mounting height position is adjustable and can be adjusted in a state of being stretched, and a holding portion that can hold the column elastically is provided at both ends of the lower frame, and is attached to the column among the holding units. In this case, a portion that can be elastically deformed by abutting on the support in preference to other portions is formed into a round shape along the embedding direction .

  In such a case, at least the mounting height position of the lower frame with respect to the column can be adjusted, so that the mounting height position of the upper frame and the lower frame with respect to the column is fixed as in the prior art. By adjusting the height position of the lower frame according to the size and material of the sheet material, the sheet material can be stretched between the upper frame and the lower frame without being loosened, and the seat The tension of the material does not act excessively as a force that causes the upper frame and the lower frame to bend toward each other, prevents deformation and damage of each frame, and prevents the upper frame and the lower frame from being detached from the column. A good mounting state of each frame can be realized. In addition, since the lower frame is held in a state of being stretched between the columns, both end portions of the lower frame are in pressure contact with the columns, and the lower frame can be prevented from being detached from the columns.

  As described above, the partition according to the present invention prevents an excessive bending force from acting on the upper frame and the lower frame, and does not depend on the tension condition or height dimension of the sheet material. The sheet material can be suitably stretched between the lower frame and without loosening.

In particular, since the holding portions that can elastically hold the columns are provided at both end portions of the lower frame, it is simply stretched between the columns by pressing in the direction of stretching between the columns and holding the columns. Compared to the state, the lower frame is more sure that the lower frame will fall off the column even when it receives an external force (impact) acting in the direction perpendicular to the surface direction of the sheet material (longitudinal direction of the lower frame) Can be prevented. In addition, since the holding portion elastically holds the support column, the attaching operation can be performed relatively easily, and unnecessary clearance can be prevented from being generated between the support column and the lower frame.

Moreover, since the part which can contact | abut to the said support | pillar preferentially over other parts when attaching to the said support | pillar among the said holding parts, and is elastically deformed along the embedding direction, it is between the support | pillars. The work of attaching the lower frame can be performed more easily and reliably. Here, the “embracing direction” is a direction in which the embedding unit embraces the column when the embedding unit is attached to the column.

  Further, the lower frame includes a long lower frame body formed of a highly rigid material, and an attachment body that is detachably provided at both ends of the lower frame body and includes the holding portion. If it is a thing, the favorable intensity | strength of a lower frame is implement | achieved and it can prevent that a lower frame bends and deform | transforms by the tension | tensile_strength of a sheet | seat material. Furthermore, if the mounting body is detachable from the lower frame body, even if one of the mounting bodies is damaged or deformed, it is only necessary to replace the mounting body. There is no need to replace it. It also contributes to maintenance.

  In order to prevent the attachment body from being detached from the lower frame body, the lower frame body has a substantially pipe shape, and the attachment body includes the holding portion and an insertion portion that can be inserted into the lower frame body. It is preferable that the insertion portion is provided with an engaging portion that can be engaged with an engaged portion provided in the vicinity of both end portions of the lower frame main body. Thereby, the relative rotation of the lower frame main body with respect to the holding portion is also restricted, and the unintentional dropout and wear damage of the attachment body due to such relative rotation can be restricted. As a specific embodiment in this case, the engaged portion is a through hole provided in the vicinity of both end portions of the lower frame main body, and the engaging portion is elastically engaged with the through hole. There are some.

  As described above, according to the present invention, as compared with the conventional aspect in which the mounting height position of the upper frame and the lower frame with respect to the support column is fixed, the lower position depends on the tension condition and the height dimension of the sheet material. The height position of the frame can be adjusted as appropriate, and can be suitably stretched between the upper frame and the lower frame without loosening the sheet material. In addition, by appropriately changing the mounting height position of the lower frame in this way, the tension of the sheet material does not act excessively as a force that causes the upper frame and the lower frame to bend toward each other. It is possible to prevent deformation / damage of the frame and to realize a good mounting state of the upper frame and the lower frame with respect to the column. Further, since the lower frame is held in a state of being stretched between the support columns, both end portions of the lower frame are brought into pressure contact with the support columns, and the lower frame can be prevented from being detached from the support columns.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the partition 1 according to the present embodiment includes a frame 2 that is assembled in a substantially rectangular shape, a pair of legs 3 that support the frame 2, and a pair of columns that constitute the frame 2. 21, an upper frame 4 that can be attached between the vicinity of the upper end portion of 21, a lower frame 5 that can be attached between the vicinity of the lower end portion of the column 21, a cross stretched between the upper frame 4 and the lower frame 5, etc. The sheet material 6 is provided.

  In the frame body 2, a pair of left and right columns 21, an upper horizontal member 22 that connects the upper ends of the columns 21, and a lower horizontal member 23 that connects the lower ends of the columns 21 are assembled together. Is. In the present embodiment, the columns 21, the upper horizontal member 22 and the lower horizontal member 23 are connected by using a joint member 24 as shown in FIG. 5 (the joint member 24 is omitted in FIG. 1). is doing). And the slot hole 21a opened inward so that it may mutually face in the site | part vicinity of the upper end part of each support | pillar 21 is each formed (refer FIG. 2 mentioned later).

  Each leg 3 includes a leg base 31 provided with casters 31c on the lower surface side, and a leg support 32 standing from the leg base 31 and having an upper end fixed to the lower horizontal member 23 of the frame 2 It is. As is clear from FIG. 1, the longitudinal direction of the leg base 31 is set in a direction substantially orthogonal to the width direction of the frame body 2 to improve the stability of the partition 1 as a whole.

  The upper frame 4 is shown in FIG. 2 (FIG. 2 is a view for explaining how the upper frame 4 is attached to the support column 21 and is a front view schematically showing a part of the partition 1 with the upper end portion partially omitted). Thus, for example, it is made of a metal round pipe member, and both ends thereof are made to function as insertion ends 41 and 42 that can be inserted into the slot holes 21 a formed in the column 21 by pressing into a flat plate shape. In the present embodiment, a hook portion 4H having a generally downward hook shape is provided at one of the insertion ends of the upper frame 4 (in this embodiment, the insertion end 42).

  As shown in FIG. 3 (the figure is an exploded perspective view of the lower frame 5), the lower frame 5 includes a long lower frame body 51 made of, for example, a metal round pipe member, and both ends of the lower frame body 51. And an attachment body 52 detachably provided on the part.

  The lower frame main body 51 has a longitudinal dimension set slightly smaller than the separation dimension of the support column 21, and is provided with through-holes 51a that are engaged portions of the present invention that open upward at both ends. In the present embodiment, the through hole 51a is a round hole.

  Each attachment body 52 is shown in FIG. 4 (FIG. 4A is a plan view of the attachment body 52, FIG. 4B is a side view thereof, and FIG. 4C is a view taken in the direction of arrow A in FIG. As shown, it is made of, for example, a synthetic resin material, and includes a holding portion 521 that can elastically hold the column 21 and an insertion portion 522 that can be inserted into the lower frame main body 51. The holding portion 521 has an inner peripheral diameter that is substantially the same as or slightly larger than the outer peripheral diameter of the support column 21, and has a substantially partial arc shape in a plan view in which the distal end portions 521 a are separated by a predetermined distance. In the present embodiment, the separation dimension between the front end portions 521a is set so that the support portion 21 can be held (turned around) the region larger than the half circumference by the holding portion 521. Further, as shown in FIG. 5B, the holding portion 521 has a portion along the holding direction X that can be elastically deformed by abutting on the pillar 21 in preference to other parts when attached to the pillar 21. The shape is round. Specifically, the upper end portion and the lower end portion of the front end portion 521a of the embedding portion 521 are formed in a partial arc shape in a side view that forms a target shape. Further, as shown in FIG. 6A, the thickness dimension of the holding portion 521 on the distal end portion 521a side is made smaller than the thickness dimension on the proximal end portion 521b side so that favorable elastic deformation can be realized. On the other hand, the insertion portion 522 extends from the proximal end portion 521b side of the holding portion 521 in the direction opposite to the holding direction X (hereinafter, the reverse direction of the holding direction X is referred to as “insertion direction Y”). A solid abutting portion 5221 having a diameter substantially the same as the outer peripheral diameter of the lower frame main body 51 and allowing both edges of the lower frame main body 51 to abut or approach each other, and further inserted from the abutting portion 5221 An insertion portion main body 5222 that extends in the direction Y and has a maximum diameter set slightly smaller than the inner peripheral diameter of the lower frame main body 51, and an engagement portion 5223 that can be engaged with a through hole 51a formed in the lower frame main body 51. It is equipped with. The engaging portion 5223 is provided at a substantially central portion in the longitudinal direction of the insertion portion main body 5222, and protrudes upward from the outer peripheral surface of the insertion portion main body 5222. The engagement portion 5223 supports the protrusion portion 5223a and is predetermined on the protrusion portion 5223a. And an elastic plate portion 5223b that can sink downward together with the projecting portion 5223a when the pressing force is applied. As shown in FIG. 5B, the protruding portion 5223a has a protruding dimension that is gradually reduced in the insertion direction Y. The elastic plate portion 5223b has a substantially rectangular shape, and only one edge portion in the insertion direction Y side is connected to the insertion portion main body 5222, and a through groove 5223c is formed between the other edge portion and the insertion portion main body 5222. Thus, it is elastically deformed so as to sink relative to the insertion portion main body 5222. In the present embodiment, the attachment body 52 is an integrally molded product that includes the embedding portion 521 and the insertion portion 522. In order to attach such an attachment body 52 to both ends of the lower frame main body 51, the attachment body 52 so that the protruding direction of the protruding portion 5223 a of the attachment body 52 matches the opening direction of the through hole 51 a of the lower frame main body 51. 52 and the position of the lower frame main body 51 are determined, and the insertion portions 522 of the respective attachment bodies 52 are inserted into both end portions of the lower frame main body 51. During this insertion operation, the protruding portion 5223a of the engaging portion 5223 gradually contacts the edge of the lower frame main body 51 and sinks downward together with the elastic plate portion 5223b, and further, the inserting portion 522 continues to be inserted and the protruding portion 5223a When reaching the through hole 51a, the protruding portion 5223a is fitted into the through hole 51a by the elastic restoring force of the elastic plate portion 5223b. As a result, the attachment body 52 is not detached from the lower frame main body 51 unless the force that presses the protrusion 5223a downward again acts on the engaging portion 5223. In this way, in a state where the attachment bodies 52 are attached to both ends of the lower frame main body 51, the edge of the lower frame main body 51 is in contact with or close to the contact portion 5221 of the insertion portion 522. The outer peripheral surface of 5221 and the outer peripheral surface of the lower frame main body 51 are substantially flush with each other, and a good appearance is exhibited.

  The sheet material 6 is formed by sewing, for example, a single cloth, has a width dimension smaller than the separation dimension between the columns 21 of the frame body 2, and has an upper frame 4 and a lower frame 5 at the upper end portion and the lower end portion, respectively. The bag-shaped part 61 which can accommodate is contained.

  Next, the procedure for stretching the sheet material 6 between the upper frame 4 and the lower frame 5 held between the columns 21 and the operation of the partition 1 of the present invention will be described with reference to FIG. In FIG. 5, the sheet material 6 is omitted.

  The upper frame 4 and the lower frame 5 are respectively accommodated in advance in the upper and lower bag-like portions 61 of the sheet material 6, and first, the upper frame 4 is held between the columns 21. Specifically, as shown in FIG. 2, of the two insertion ends 41, 42 of the upper frame 4, the insertion end 41 that is not formed with the hook portion 4 H is inserted into the slot hole 21 a of one column 21. Then, the insertion end 42 on which the hook portion 4H is provided is hooked so as to drop into the slot hole 21a of the other column 21. Subsequently, as shown in FIG. 5A, the holding portion 521 of one attachment body 52 of the lower frame 5 is inserted into the vicinity of the lower end portion of the one column 21 from above. At this time, the holding portion 521 holds one column 21 while gradually elastically deforming. Next, when the lower frame 5 is rotated in the direction in which the other holding portion 521 approaches the other support column 21 with the portion held in the holding portion 421 as a fulcrum, the holding portion of the other attachment body 52 is gradually changed. 521 comes into contact with the other support column 21 and elastically deforms to embrace the support column 21 (see FIG. 5B). In this state, the mounting height positions of the one holding portion 521 and the other holding portion 521 with respect to each column 21 are different (that is, the lower frame 5 is at a predetermined angle with respect to the lower horizontal member 23 of the frame body 2). It becomes an inclined angle), and the respective holding portions 521 are not in a state of completely holding the column 21 respectively. Therefore, when the lower frame 5 is further rotated in the same direction until the mounting height position of each embedding portion 521 with respect to each column 21 is substantially the same, the lower frame 5 is held in a state of being stretched between the columns 21. Then, each holding portion 521 is in a state of completely holding the column 21 (see FIG. 5C). In this state, the embedding portion 521 embraces the support column 21, while applying a force larger than the frictional force between the embedding portion 521 and the support column 21 along the height direction of the support column 21. The mounting height position with respect to each column 21 can be adjusted in a state where 5 is stretched between the columns 21, and the mounting height position of the lower frame 5 is positioned at a position where a good tension is applied to the sheet material 6. Thus, the sheet material 6 can be stretched between the upper frame 4 and the lower frame 5 without being loosened.

  In addition, what is necessary is just to pass through the reverse procedure to the attachment procedure mentioned above in order to remove the lower flame | frame 5 from the support | pillar 21. FIG. In this case, since the embedding portion 521 has a round shape, one of the embedding portions 521 is separated from the support column 21 with the embedding portion of the other embedding portion 521 as a fulcrum so as to release the stretched state. It can be easily removed by rotating in the direction.

  Thus, since the partition 1 which concerns on this embodiment can adjust the attachment height position with respect to the support | pillar 21 of the lower frame 5, the attachment height position with respect to the support | pillar of an upper frame and a lower frame is fixed like the past. Compared to the above-described embodiment, the tension of the sheet material 6 causes the upper frame 4 and the lower frame 5 to be mutually adjusted by adjusting the mounting height position of the lower frame 5 according to the height dimension and tension of the sheet material 6. The sheet material 6 can be stretched between the upper frame 4 and the lower frame 5 in a state where a moderate tension is applied without being excessively applied as a force to bend in the direction approaching the frame. In addition, since the lower frame 5 is stretched between the support columns 21, both ends of the lower frame 5, that is, the holding portions 521 are in pressure contact with the support columns 21, respectively, and the lower frame 5 is prevented from being detached from the support columns. can do. In this way, deformation / damage of the frames 4 and 5 can be prevented, and a good attachment state of the frames 4 and 5 and a good tensioning state of the sheet material 6 can be realized.

  In addition, when the holding portions 521 provided at both ends of the lower frame 5 are held in a state in which each of the columns 21 is pressed between the columns 21, the surface of the sheet material 6 with respect to the lower frame 5 Even when an external force (impact) acting in a direction perpendicular to the direction (longitudinal direction of the lower frame 5) is applied, the lower frame 5 can be reliably prevented from falling off the support column 21. Further, it is possible to avoid a clearance between the support column 21 and the lower frame 5 by the holding portion 521, and it is possible to maintain a good mounting state / holding state. Moreover, since the embedding part 521 can embrace the support column 21 with elastic deformation, the embedding part 521 can be held in the support column 21 by attaching the embedding part 521 to the support column 21. Contributes to simplification of installation work.

  In particular, in the embedding portion 521, when attaching to the support column 21, the portion that can be elastically deformed by contacting the support column 21 with priority over other sites is formed in an arc shape along the embedding direction X. It is possible to more easily and accurately perform the attaching operation and the detaching operation of the embedding portion 521 with respect to.

  In addition, the lower frame 5 is a long lower frame body 51 formed of a highly rigid material, in this embodiment, a metal material, and an attachment provided at both ends of the lower frame body 51 and provided with a holding portion 521. Since the body 52 is provided, even if the tension of the sheet material 6 acts as a force to bend the lower frame 5, it is possible to prevent the bending deformation from occurring due to the rigidity of the lower frame body 51. Is possible.

  Since the attachment body 52 is detachable with respect to the lower frame body 51, if the attachment body 52 or the lower frame body 51 needs to be replaced due to damage due to excessive impact or aging, the damage / It is only necessary to replace the deformed parts, and it is not necessary to replace the entire lower frame 5. It also contributes to maintenance.

  Further, the lower frame main body 51 has a substantially pipe shape, and the attachment body 52 includes a holding portion 521 and an insertion portion 522 that can be inserted into the lower frame main body 51. Since the engaging portion 5223 that can be engaged with the through-hole 51a provided in the upper portion is provided, the attachment body 52 is prevented from being detached from the lower frame main body 51, and the engaging portion 5223 can The relative rotation of the lower frame main body 51 is also restricted, and the unexpected drop and wear of the attachment body 52 due to such relative rotation can be restricted.

  Since the engagement portion 5223 is the through hole 51a provided in the lower frame main body 51 and the engagement portion 5223 is elastically engaged with the through hole 51a, the engagement portion 5223 is engaged. The manufacturing process can be simplified and the cost can be reduced effectively, and the attachment work of the attachment body 52 to the lower frame body 51 can be easily performed.

  The present invention is not limited to the embodiment described in detail above.

  For example, the round shape applied to the embedding part and the separation distance between the front end parts of the embedding part may be changed as appropriate in accordance with the shape, the diameter, etc. of the support post.

  Further, the lower frame may be provided integrally with the lower frame main body and the attachment body. In this case, the lower frame only needs to be strong enough not to bend and deform due to the tension of the sheet material.

  When the attachment body is detachable from the lower frame main body, a guide groove for guiding the engaging portion to the engaged portion when the attachment body is inserted may be formed in the lower frame main body. Thereby, the attachment operation | work of the attachment body with respect to a lower frame can be performed smoothly. In addition, the engaging portion provided in the insertion portion of the attachment body is changed to the engaged portion provided in the lower frame body by displacing the phase between the attachment body and the lower frame body while the attachment body is inserted into the lower frame body. You may make it engage with. In this case, examples of the engaging portion and the engaged portion include a protruding portion and a groove in addition to the protruding portion, the elastic plate portion, and the through hole shown in the embodiment.

  Furthermore, in the said embodiment, although the lower frame illustrated the aspect provided with the embedding part in both ends, it is not restricted to this, The pressure which presses each support | pillar in the state stretched between support | pillars at the both ends of a lower frame You may employ | adopt the aspect which provided the part (contact part). Even in this case, the height position can be adjusted in a state where the lower frame is stretched between the columns, and the above-described effects can be obtained.

  Moreover, you may employ | adopt the aspect hold | maintained so that not only a lower frame but the upper frame is also stretched between support | pillars so that an attachment height position can be adjusted. In this case, when adjusting the mounting height position of either the lower frame or the upper frame, the frictional force between the frame and the column is prevented so that the other frame does not move along with the movement of the one frame. However, the height position of the upper end portion of the sheet material can be adjusted, so that the partition can flexibly meet the needs of the user.

  In addition, although the partition using the single frame was shown in the said embodiment, the continuous type partition which connected the some frame with the appropriate means so that a relative angle change is possible may be sufficient.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
