Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a mounting structure for a film member. More specifically, the present invention provides a method for easily attaching a membranous member to a structure that functions as an elastic wall material of a partition, or as a seat or a backrest of a chair, as an elastic supporting element of the structure. Regarding mounting structure.

[0002]

2. Description of the Related Art A chair 102 is known in which a seat 103 is directly attached to a leg portion composed of a pipe frame 101 as shown in FIGS.
8673). The seat 103 of the chair 102 is a frame-shaped support member 10 that is screwed and fixed on a bracket 108 welded to the pipe frame 101 with a bolt 109.
4, a film-like member 105 made of a mesh sheet integrated with the frame-like supporting member 104, a cushion 106 placed on the film-like member 105, and a frame covering the cushion 106 and the frame-like supporting member 104. The upholstery material 107 is provided so as to wrap around from the outside of the strip-shaped support member 104 to the back side and be fixed. In FIG. 11, reference numeral 110 indicates a nut screwed into the bolt 109, and reference numeral 111 indicates a nut receiving hole of the frame-shaped support member 104.

The frame-shaped support member 104 in which the film-shaped member 105 is integrated, that is, a so-called shell-shaped structure is formed by insert molding. For example, as disclosed in Japanese Patent Publication No. 7-37049, this formation is performed by using a pair of clamp mechanisms 113 arranged outside the mold 112 so as to sandwich the mold 112, as shown in FIG. The member 105 is sandwiched and positioned between the dies 112. At this time, the tension applying mechanism 114 pulls the clamp mechanism 113 in the direction away from the mold 112 (indicated by an arrow in the drawing) to apply the necessary tension to the film member 105 as the seat 103. Then, the mold 112 is clamped and injection molding is performed to integrate the frame-shaped support member 104 and the film-shaped member 105. Further, after the frame-shaped support member 104 is cured, it is removed from the mold 112, and the film-shaped member 105 protruding from the peripheral edge of the frame-shaped support member 104 is cut off. This completes the structure.

Further, as shown in FIG. 13, the frame-shaped supporting member is composed of an inner frame 121 and an outer frame 122, and the film-shaped member 105.
Is fixed in advance by the clamp mechanism 120, and the inner frame 12
It is also practiced to fix the film-shaped member 105 to the frame-shaped support member in a tensioned state by sandwiching the film-shaped member 105 between the outer frame 122 and the outer frame 122 and screwing the film-shaped member 105.

Further, also in the field of partition, a film-like member such as a mesh, a film or a cloth is adopted as a wall material to replace the hard impression received when a hard material such as a steel plate or a plate material is adopted. , It is considered to give a soft and warm impression and a touch and texture. In this case, it is necessary to attach the film member to the frame without loosening it. Therefore, in order to attach the film-shaped member to the frame in a state in which a constant tension is applied by pulling the film-shaped member, for example, as in the case of manufacturing a chair seat shown in FIG. It is conceivable that the film-shaped member thus formed is sandwiched and fixed with screws or the like. Further, while the film-shaped member is being fixed to the frame, the film-shaped member is continuously pulled and tensioned outside the frame, so that part or all of the peripheral edge of the film-shaped member protrudes from the frame after mounting. . Therefore,
As a terminal treatment for covering the peripheral edge portion of the film-shaped member that is protruding from the frame to improve the appearance, for example, a decorative frame that covers the peripheral edge portion is required.

[0006]

However, as shown in FIG.
To the frame-shaped support member 10 shown in FIG.
In the method of attaching the resin to No. 4 by resin-integral molding, an expensive die investment is required and the cost becomes high. On the other hand, in the method of attaching the film member 105 shown in FIG. 13, workability is poor, for example, it is necessary to fix the film member 105 in advance before attachment, and the frame-shaped support member is used as the inner frame 121 and the outer frame. 12
Since it is composed of two parts, the number of parts increases and the cost increases.

This is also the case with partitioning, which requires a special jig and equipment for assembling, and has a problem that assembly workability is troublesome and the cost is high. Further, there are problems that the number of parts is large and the cost is high, and the advantage of using the elastic wall material made of a film-shaped member cannot be fully utilized. That is, there is a problem that the material, color, design, etc. of the film-shaped member cannot be freely changed according to consumer preference.

Therefore, the present invention provides a structure which functions as a seat or a backrest of a chair, as an elastic supporting element for the structure,
Another object of the present invention is to provide a membrane member mounting structure that can be easily attached and detached as an elastic wall material for partitioning without requiring a special jig or tool. Further, the present invention provides a membrane-like member with elasticity and tension required as an elastic support element such as a chair seat or a backrest or as an elastic wall material for partitioning, to the structure or the like at a simple and low cost. An object of the present invention is to provide a mounting structure for a film-shaped member to which a member can be mounted.

[0009]

In order to achieve the above object, the invention according to claim 1 is a structure comprising a frame and a film-like member having a peripheral portion attached to the frame and extending the film. The frame member is provided with a locking member that is fixed to the surface of the peripheral portion of the peripheral member facing the frame body at the outer peripheral portion and is separated from the film-shaped member so that the end portion inside the frame member can be rolled up. The receiving portion that abuts the inner end portion of the locking member that is pulled by such an inward tension, and the outer peripheral edge portion of the film member is supported by the inner end portion of the locking member as a fulcrum by the film member tension. And a hooking portion that prevents the rolling member from turning so as to spread in a direction by hitting the fixing end portion of the locking member to the film-shaped member and applying a tension direction to the film-shaped member between the receiving portion and the hook portion. Has an engaging groove provided with an insertion port for a locking member that opens in the opposite direction, and is required as a structure for the film-shaped member. In a state where tension is applied to exert a force of, the locking member is hooked between the pledged receiving portion and the hook portion to engage the groove is engaged, and to attach to the frame of the film member.

Therefore, while pulling the film-shaped member, the locking member on the periphery of the film-shaped member is inserted into the engaging groove of the frame body, and the inner end of the locking member is received in the receiving portion. The film-shaped member is attached to the frame body in a stretched state in a stretched state only by hooking the portions on the hook portions. Moreover, when the locking member is inserted into the locking groove of the frame body, since the periphery of the film-shaped member is reversed and wound so as to wrap the frame member, the film member is fixed at the same time as it is attached. Since the length is longer, a stronger tension can be applied to the film member, and the film member can be strongly fixed to the engagement frame. Further, if the film-shaped member and the locking member housed in the engagement groove, particularly the fixed end portion is pushed in so as to be separated from the hook portion, the locking member tilts along the film-shaped member,
It slides on the receiving portion and is pulled out of the engagement groove by the pulling force of the membrane member.

According to a second aspect of the present invention, there is provided a mounting structure for a membrane-like member, wherein the membrane-like member is attached to a structure that functions as a seat or a backrest of a chair as an elastic supporting element. A locking member that is fixed to the surface of the peripheral edge facing the structure at the outer peripheral edge and separates from the film-shaped member so that the inner end of the structure can be rolled up is provided. The receiving portion that abuts the inner end of the locking member that is pulled by the tension, and the outer peripheral edge portion of the film-shaped member spreads outward with the inner end of the locking member as a fulcrum by the tension of the film-shaped member. Has a hook portion that prevents the rolling member from turning around by hitting the fixing member to the film member, and a direction opposite to the direction in which the tension of the film member is applied between the receiving portion and the hook portion. The engaging frame that forms the engaging groove with the insertion port for the locking member that opens at the With the tension applied to the film-like member to exert the elasticity required as an elastic support element, the locking member is inserted into the engaging groove of the engaging frame and hooked between the receiving portion and the hook portion. The membrane member is attached to the engagement frame.

Therefore, while pulling the film-shaped member, the locking member on the periphery of the film-shaped member is inserted into the engaging groove of the engaging frame of the structure, and the inner end portion of the locking member is received in the receiving portion, and the film-shaped member on the tip side. The membranous member is attached to the engaging frame in a stretched state in a stretched state only by hooking the fixed end portions of the members on the hooks. Moreover, when the locking member is inserted into the locking groove of the engagement frame, since the peripheral edge of the film-shaped member is inverted and rolled up so as to wrap the engagement frame, the film-shaped member is fixed at the same time as mounting. Since the pulling distance becomes long, stronger tension can be applied to the film-shaped member, and the film-shaped member can be strongly fixed to the engagement frame. Then, a chair structure that functions as a seat or a backrest using the film-shaped member as an elastic support element is configured. Also, if the film-shaped member and the locking member housed in the engaging groove, especially the fixed end portion is pushed in so as to be separated from the hook portion,
The locking member tilts along the film member, slides on the receiving portion, and is pulled out of the engagement groove by the tensile force of the film member.

According to a third aspect of the present invention, in the attachment structure for the membrane member according to the second aspect, all or part of the frame forming the seat or backrest of the chair is an engaging frame. In this case, the engagement frame functions not only as a support member that holds the peripheral edge of the film-shaped member, but also as a frame that forms a seat or backrest of a chair. Therefore, it is possible to reduce the number of parts of a structure that functions as a seat or a backrest of a chair.

According to a fourth aspect of the present invention, in the attachment structure for the membrane member according to the second or third aspect, the upper edge of the frame of the structure is arranged above the hook portion of the engaging frame. The frame and the engagement frame are joined to each other, the locking member insertion port of the engagement frame is hidden from the side, and a gap for inserting the locking member in the engagement groove is provided from above. . In this case, the locking member inserted into the locking groove of the engaging frame and the film-shaped member are hidden by the frame, so that the appearance is decoratively good. Therefore, it is not necessary to separately prepare a frame for decoration, which is advantageous in terms of cost.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The structure of the present invention will be described below in detail based on the embodiments shown in the drawings.

1 to 4 show an example in which one embodiment of the attachment structure for a film-like member of the present invention is applied to a seat of a chair. The membranous member 2 in this embodiment is attached to a seat frame as an elastic supporting element of a seat (structure), and constitutes a seat surface by itself, or urethane foam or upholstery is placed on it. It functions as a substitute for a supporting seat plate. The attachment of the film member 2 to the seat frame, which is a structure, is such that the locking member 3 provided on the peripheral edge of the film member 2 is elastically supported by the engagement groove 5 of the engagement frame 4 provided on the seat frame. The film-like member 2 is inserted in a state in which a tension for exerting the required elasticity as an element is inserted, and the locking member 3 pulled by the tension of the film-like member 2 is inserted into the receiving portion 6a and the hook portion 6b of the engaging frame 4. Membrane member 2
Is attached to the engagement frame 4.

In this embodiment, the seat frame itself of the chair is the engagement frame 4 (see FIG. 4). That is, the engagement frame 4 of the present embodiment functions as a support member that holds the peripheral edge of the film-shaped member 2 and also functions as a seat frame of a chair. The engagement frame 4 is made of, for example, a metal, and it is preferable to use a plated steel plate, a lightweight and highly rigid aluminum alloy, a zinc die cast, or the like. The engagement frame 4 has, for example, a rectangular frame shape and is attached to the pipe frame 7 that constitutes the leg portion of the chair. The mounting method is not particularly limited, but in the present embodiment, the engagement frame 4 is mounted to the pipe frame 7 by welding, for example. However, the present invention is not limited to this, and it may be attached by screwing, and for example, a locking claw is integrally formed on the engaging frame 4, and this can be attached to the receiving portion on the pipe frame 7 side, for example, a hole or a concave portion with one touch. It may be locked. In the present embodiment, the film member 2
Before attaching the fitting frame 4 to the pipe frame 7
I'm trying to attach it in advance. However, the engagement frame 4 may be attached to the pipe frame 7 after the film-shaped member 2 is attached. In addition, the engagement frame 4 and the pipe frame 7 (or the engagement frame 4
When the seat frame is provided separately from, the mounting relationship or dimensional relationship with the seat frame is such that the upper end edge of the pipe frame 7 is arranged above the hook portion 6b of the engaging frame 4. (As indicated by the phantom line), the pipe frame 7 and the engagement frame 4 are joined, the locking member insertion port 6c of the engagement frame 4 is hidden by the pipe frame 7 from the side, and the engagement groove from the upper side. A clearance for inserting the locking member 3 is provided in 5. In this case, since the locking member 3 and the film-shaped member 2 inserted into the locking groove 5 of the engagement frame 4 are hidden by the frame 7, it is also decoratively attractive. Therefore, it is not necessary to separately prepare a frame for decoration, which is advantageous in terms of cost.

The engaging frame 4 includes a receiving portion 6a for contacting an inner end of the locking member 3 pulled by the inward tension applied to the film member 2 and an outer peripheral edge portion of the film member 2. A hook that prevents the inner end portion 3a of the locking member 3 from rolling outward so as to spread outward by the tension of the film member 3 by hitting the fixed end portion 3b of the locking member 3 to the film member 2. An engaging groove 5 having a portion 6b, and an insertion port 6c for the locking member 3 which opens in the direction opposite to the direction in which the tension of the film member 2 is applied between the receiving portion 6a and the hook portion 6b. Constitute. More specifically,
For example, in this embodiment, the engagement frame 4 has a cross-sectional shape as shown in FIGS. In this case, the engagement frame 4 includes the wall portion 8 located in the direction orthogonal to the plane on which the film member 2 is stretched, and the end of the wall portion 8 on the side where the film member 2 is stretched from the wall portion 8 of the film member 2. The receiving portion 6a protruding in the direction of pulling the film-shaped member 2 when attached (indicated by the arrow P in FIG. 1, hereinafter simply referred to as the pulling direction P), and the wall portion 8 on the opposite side of the receiving portion 6a. And a hook portion 6b protruding in a U-shape in the pulling direction P from the end. A space surrounded by the receiving portion 6a, the wall portion 8 and the hook portion 6b forms the engaging groove 5. The gap between the tip of the receiving portion 6a and the tip of the hook 6b is the opening into which the locking member 3 is inserted, that is, the insertion opening 6
c. Therefore, the entrance 6c of the engagement groove 5 into which the locking member 3 is inserted is provided outward in the direction opposite to the tension direction of the film member 2. Receiver 6a and hook 6b
Has a lock function of hooking and fixing the locking member 3 pulled by the tension of the film-shaped member 2. Also, the receiving portion 6
The a and the hook portion 6b also serve as a flange of the engagement frame 4, enhance the rigidity of the engagement frame 4 against bending and twisting, and enhance the function of the engagement frame 4 as a seat frame.

The locking member 3 of the present embodiment is fixed to the surface of the film-shaped member 2 facing the structure at the outer peripheral edge portion 3b, and the end portion 3a on the inner side thereof is rolled up. It is provided to be separated from the member. That is, the film-shaped member 3
The inner end portion 3a of the above is raised so that it can be oriented in a direction different from that of the film member 2. The locking member 3 is made of, for example, a plate (flat plate) made of metal, hard plastic, wood, plywood or the like having a size that can be accommodated in the engagement groove 5. The locking member 3 is fixed to each peripheral portion of the four sides of the film-shaped member 2 formed in a rectangular shape by an appropriate joining means such as sewing, riveting, stacking, adhesion, and welding. In the present embodiment, the locking member 3 is fixed to the film-shaped member 2 by sewing, for example. However, the method is not limited to this, and any method may be used as long as the fixing portion of the locking member 3 can withstand the tension of the film-shaped member 2.

The fixing position (sewn portion) 2a of the film-shaped member 2 on the locking member 3 is hooked and locked by the locking member 3 in the engaging groove 5 as shown in FIG. 3 in this embodiment. At this time, the position is such that it comes into contact with the hook portion 6b. In this case, a part of the film member 2 can be sandwiched between the locking member 3 and the hook portion 6b, and the film member 2 can be more strongly attached to the engagement frame 4. Further, the film member 2 and the locking member 3
It is also preferable from the viewpoint of appearance since the fixed portion (sewn portion) with and does not have to be hidden and exposed inside the engagement frame 4. Further, since the distance for pulling the film member 2 at the time of attaching the film member 2 becomes long, stronger tension can be applied to the film member 2. In addition, the cutting size of the film member 2 and the fixing position 2a of the film member 2 and the locking member 3 are adjusted so that the film member 2 is given a predetermined tension for exhibiting the required elasticity.

Here, as the film-shaped member 2, a mesh, a film, a cloth, a non-woven fabric or the like can be applied, but a mesh sheet is particularly preferable. Among them, a recyclable olefin resin-made or polyester mesh sheet is preferable, and for example, the use of a woven fabric of polyester yarn and elastomeric polyester yarn (for example, a mesh sheet known as Dymetrol under the trade name of DuPont). preferable. This polyester mesh sheet has less settling. And
Since the mesh sheet has good elasticity and air permeability, it is possible to obtain a comfortable and comfortable seat. However, the membranous member 2 is not particularly limited to the above mesh sheet, and is made of a material / structure / composition that exhibits sufficient rigidity and elasticity as an elastic supporting element of the structure (eg seat) 1. Things are used appropriately.

The seat 1 configured as described above is assembled by, for example, the procedure shown in FIGS. 1 to 3 and by attaching the film member 2 to the engagement frame 4 which constitutes the seat frame in this embodiment. First, the engagement member 3 is inserted into the engagement groove 5 of the engagement frame 4 illustrated on the right side in FIG. 1 without pulling the film member 2. Then, while pulling the film-shaped member 2 in the arrow P direction in a position opposite to this position, that is, in the engagement groove 5 of the engagement frame 4 illustrated on the left side in FIG. 1,
The peripheral edge of the film member 2 and the locking member 3 are inserted so as to be bent (see FIG. 2). The locking member 3 housed in the engagement groove 5 is pulled in the Z direction and the X direction by the tension of the film-shaped member 2, and the inner end 3a of the locking member 3 is received by the receiving portion 6a.
Further, the fixed end portion 3b of the locking member 3 turns so as to spread outward with the inner end portion 3a as a fulcrum, and hits the hook portion 6b to be caught (see FIG. 3). That is, the film member 2
The movement of the locking member 3 in the horizontal direction (indicated by the X direction in FIG. 3) due to the tension is hindered by the hook portion 6b, and the locking member 3 in the vertical direction (indicated by the Z direction in FIG. 3). Movement is hindered by the receiving portion 6a. The higher the tension of the film member 2 is, the larger the contact pressure between the locking member 3 and the receiving portion 6a and the hook portion 6b is.
Strongly fixed to. The tension acting on the film member 2 in this state is set so as to exert the elasticity required for the seat. Further, the film member 2 and the locking member 3 housed in the engagement groove 5, especially the fixed end portion 3b.
Is pushed away from the hook 6b, the locking member 3 tilts along the film member 2, slides on the receiving portion 6a, and is pulled out of the engaging groove 5 by the pulling force of the film member 2. (State of FIG. 2). As a result, the film member 2 is attached to the engaging frame 4
Can be removed from.

According to the attachment structure of the film member, the film member 2 can be attached very easily and at low cost. That is, it is not necessary to invest a large amount of money such as a mounting method in which the film-shaped member and the seat frame are integrally molded with resin. In addition, the number of parts can be reduced as compared with the structure in which the membrane member 2 is sandwiched between the inner frame and the outer frame, and it is not necessary to separately pretension the membrane member 2 with a clamp mechanism or the like, and the attachment work can be performed. It will be easy.

Further, since the engaging frame 4 serving as a tension member can be provided with the engaging groove 5 to have a J-shaped cross section, the cross sectional area of the engaging frame 4 can be reduced without lowering the rigidity. Be advantageous.

Further, the cutting size of the film member 2 and the film member 2
Since the tension applied to the film-shaped member 2 can be adjusted by adjusting the fixing position of the locking member 3 and the like, a desired tension can be obtained easily and stably.

An example in which the attachment structure of the film-shaped member of the present invention is applied to a partition will be described with reference to FIGS. 8 and 9.
In the present embodiment, the same components as those in the above-described embodiment will be designated by the same reference numerals, detailed description thereof will be omitted, and a structure peculiar to the partition will be described.

The partition 21 of this embodiment employs the film member 2 as a wall material having elasticity.
It is constituted by tightly attaching the film-shaped member 2 to the frame 4 forming the contour shape of the partition 21, and gives a soft and warm impression and the touch and material feeling of the film-shaped member 2.

Here, the frame body 4 functions not only as a support member for holding the peripheral edge of the film-shaped member 2 but also as a skeleton that defines the form of the partition 21, and takes an arbitrary frame shape and a film. An engagement groove is provided on an outer surface that intersects with the surface on which the strip-shaped member 2 is stretched so as to open the insertion port 6c of the locking member 3. The frame body 4 does not need to be structurally made of a material and thickness having high rigidity, except for the case where it is expected to support a particularly large load, but is usually an aluminum alloy embossing material. And drawing materials, plated steel plates and pipe materials, zinc die cast, which is lightweight and excellent in rigidity, plastics, etc. are mainly used, and in some cases wood etc. are also used. Frame 4
May be provided with legs so as to be self-supporting, or may be equipped with a fixture (not shown) to be supported by furniture such as a desk or a table. Further, it is preferable that the frame body 4 is formed so as to be divided into several parts and can be connected by a joint or the like. In this case, the film-shaped member 2 is required for transportation.
The frame body 4 can be compactly stored by further separating the frame body 4 and the frame body 4. Further, in addition to the frame body 4 having the engagement groove 5, a frame member (not shown, which corresponds to the pipe frame 7 in FIG. 1) having a leg portion and a fixture is provided,
The frame body 4 may be further attached to the frame material. In this case, the locking member insertion port 6c of the frame body 4
Is hidden from the side with a frame material, and the engagement groove 5 is seen from above.
By providing a gap for inserting the locking member 3 into the locking member 3, the locking member 3 and the film-shaped member 2 inserted into the locking groove 5 of the frame body 4 are inserted.
Since and are hidden by the frame material, they will be even more visually appealing. Therefore, it is not necessary to separately prepare a frame for decoration, which is advantageous in terms of cost.
Of course, since only the frame body 4 hides the sewn portion of the film-shaped member 2 and the edge of the locking member 3 with the hook portion 6b, the appearance does not deteriorate.

The engaging groove 5 has a receiving portion 6a for abutting the inner end portion 3a of the locking member 3 pulled by the inward tension applied to the film member 2, and the film member 2 of the locking member 3. A hook that prevents the outer peripheral edge portion of the film-like member 2 from hitting the fixed end portion 3b to the outer edge of the film-like member 3 and outwardly spreading from the inner end 3a of the locking member 3 as a fulcrum. Has a portion 6b,
The insertion port 6c of the locking member 3 that opens between the receiving portion 6a and the hook portion 6b in the direction opposite to the direction in which the tension of the film-shaped member 2 is applied.
Is provided. That is, the engaging groove 5 into which the locking member 3 is inserted
The inlet 6c is provided outward in the direction opposite to the tension direction of the film member 2, and the receiving portion 6a and the hook portion 6b are provided.
Has a lock function of hooking and fixing the locking member 3 that is pulled by the tension of the film-shaped member 2. Further, the receiving portion 6a and the hook portion 6b also serve as a flange in the frame body 4, enhance the rigidity of the frame body 4 against bending and twisting, and enhance the function of the frame body 4 as a seat frame.

The film-shaped member 2 is made of a material / structure / composition that exhibits sufficient rigidity and elasticity as a structural material, unlike the case of the above-described embodiment used for a chair seat or backrest. It does not have to be a material, but a material that gives a certain amount of tension.
Any structure can be adopted as long as it has suitable structure and material from the viewpoint of function as a partition and decorativeness. For example, as the membrane member 2 as a partition, almost all materials such as cloth, woven fabric, non-woven fabric, mesh and film made of natural fibers or synthetic fibers can be used. For example, a cloth or mesh sheet made of olefin resin or polyester resin, for example, a woven fabric of polyester yarn and elastomeric polyester yarn (known as Dymetrol, manufactured by DuPont) is preferable because it is recyclable. Moreover, since this dymetrol has less fatigue and is a mesh sheet, it has good elasticity and breathability, so it does not loosen even for long-term use and acts as a partition to block the line of sight while at the same time It enables distribution and creates a comfortable and comfortable environment without hindering air conditioning. Of course, if you use other materials with a mesh structure, you can achieve effects such as blocking the line of sight and breathability, and further, the unique feel and luster of each material brings about the elegance and refreshing feeling. Will create a more comfortable environment.

Partition 2 constructed as described above
As shown in FIG. 9, 1 is assembled by simply inserting the locking member 3 at the end of the film member 2 into the engaging groove 5 of the frame body 4. That is, the locking member 3 is inserted into the engaging groove 5 on one side of the frame body 4 without pulling the film member 2. Then, while pulling the film-shaped member 2 into the engaging groove 5 on the side opposite to this position, the peripheral edge of the film-shaped member 2 sewn with the locking member 3 is inserted so as to be bent toward the frame body 4 side. Similarly, for the remaining sides, the locking members 3 at the peripheral edge are inserted into the corresponding engaging grooves 5. As a result, the film-shaped member 2 is attached to the frame body 4 in a state in which the film-shaped member 2 is taut without being loosened. Also,
If the film-shaped member 2 and the locking member 3 housed in the engaging groove 5 and particularly the fixed end portion 3b are pushed away from the hook portion 6b, the locking member 3 will be a film as in the above-described embodiment. The film-shaped member 2 is inclined along the member 2, slides on the receiving portion 6a, and is pulled out of the engaging groove 5 by the tensile force of the film-shaped member 2. As a result, the film member 2 can be removed from the frame body 4.

Partition 2 constructed as described above
1 has an advantage that a dedicated jig and equipment for assembling are not required, the assembling workability is not troublesome, and the cost is low. Moreover, since it can be easily assembled in the office and can be disassembled, the size during transportation can be made extremely small and the transportation cost can be reduced. Moreover, since the replacement of the film member 2 can be easily performed in an office or the like, the material, color, design, etc. of the film member 2 can be freely set according to the office environment or the like of a person working there. Can be selected and changed. Further, even when the membrane member 2 and the wall material are dirty or damaged, they can be easily removed and washed or replaced. Furthermore, the number of parts is small and the cost is low. Further, it is not necessary to invest a large amount of money such as a method of mounting the film-shaped member and the seat frame by resin integral molding. In addition, the number of parts can be reduced as compared with the structure in which the membrane member 2 is sandwiched between the inner frame and the outer frame, and it is not necessary to separately pretension the membrane member 2 with a clamp mechanism or the like, and the attachment work can be performed. It will be easy.

The above-described embodiment is an example of the preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention.

The cost can be reduced significantly. At the same time, the number of parts can be reduced, so that the cost can be reduced. Moreover, the attachment and detachment of the film-shaped member to the frame does not require a dedicated jig or equipment, and can be easily carried out manually or with the use of a simple tool. You can freely select and change the material, color, design, etc. Further, even when the membrane member / wall material is dirty or damaged, it can be easily removed and washed or replaced. This is useful when applied to partitions.

Further, according to the attachment structure of the film member according to the second aspect, the locking member is inserted into the engaging groove in a state in which the film member is provided with a tension for exhibiting elasticity required as a chair structure. Just by hooking it, it will be stretched around the engaging frame by exerting the elasticity required as an elastic support element of the structure, so it is not necessary to pre-tension the membrane member with a separate clamp mechanism etc. Is easy. Moreover, the attachment of the film member to the structure can be performed very easily and at low cost. Further, compared to the mounting method in which the mounting portion of the structure and the integral mounting of the film-shaped member are simultaneously performed by resin molding using a mold, a large amount of mold investment is not required, so a small amount is required. A low-cost mounting structure suitable for production. Further, compared to a structure in which a film-shaped member is sandwiched between an inner frame and an outer frame, the supporting strength is comparable, and the number of parts can be reduced. Further, as compared with the structure in which the mounting portion of the structure and the film-shaped member are integrated by resin molding, a large amount of die investment is not required, so that the mounting structure is low cost and suitable for small-volume production. Moreover, since the engaging frame and the film-shaped member can be easily disassembled as necessary, replacement, repair, washing, etc. of the film member can be performed. Further, it is possible to freely select the material of the seat or backrest, the film structure, the color, etc. when purchasing or using the chair.

Furthermore, according to the attachment structure of the film member according to the third aspect, the engagement frame not only functions as a support member for holding the peripheral edge of the film member, but also serves as a seat or a backrest of a chair. It also functions as a frame to form. Therefore, it is possible to reduce the number of parts of the structure that functions as a seat or a backrest of the chair, and further reduce the cost.

Further, according to the mounting structure of the film member according to the fourth aspect, the edges of the film member and the locking member inserted into the engaging groove are hidden by the hook portion of the engaging frame, which is decorative. It also looks good, does not require a frame for decoration, and can reduce the cost of parts.
