[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a hanging member for hanging a cushion cover and integrating the cover, pad, and frame.

[Conventional technology]

Conventionally, this kind of cushion cover was hung by folding a hanging cotton cloth 50 twice the required length in the width direction along the center line in the width direction, and lengthening the vicinity of both ends, as shown in FIGS. 8 and 9. After basting in the horizontal direction, the basting part is sewn and fixed to the back side of the cover 51 along the hanging design line 52. Thereafter, the hanging wire 53 is inserted into the bag-shaped hanging cotton cloth, the hanging cotton cloth 50 and the hanging wire 53 are temporarily fixed with staples, etc., to prevent the hanging wire 53 from shifting or falling off, and then inserted into the pad 54. inserted insert wire 5
5, a hanging wire 53 was fastened with a C ring 56 to carry out hanging.

Furthermore, a suspension structure in which an anchor clip is engaged with a resin net instead of fastening the insert wire and the C ring is disclosed in Japanese Utility Model Application Publication No. 57-113065.

In addition, a suspender clip having a locking part at the upper end that is locked to the back surface of the seat skin and an engaging part that engages with the pad support member at the other end is passed through the through hole of the pad support member, and the suspender clip is inserted into the through hole of the pad support member. A suspension device for suspending a pad from a pad support member side is disclosed in Japanese Utility Model Application Publication No. 113000/1983.

[The problem that the idea attempts to solve]

Hanging work using conventional C-rings requires a high level of skill on the part of the operator, and variations in the fastening positions of the C-rings, hanging members, and insert wires can cause meandering of the hanging wires, misalignment of the cover and pad, etc. This had a negative impact on the quality of the finished product. Furthermore, attaching the hanging member to the cover is inefficient, requiring a large number of man-hours such as sewing and threading the hanging wire.

Furthermore, both the C-ring suspension and the anchor clip suspension require an insert wire or a resin net to lock the suspension member in the pad, making the insert time-consuming and costly.

Furthermore, when the cushion is bent due to the weight of the passenger or the vibration of the vehicle, the suspender clip has the disadvantage that the suspender clip gives the passenger a feeling of a foreign object or a feeling of hitting the bottom.

Therefore, the present invention has developed a hanging member that allows even unskilled workers to perform hanging work easily and quickly, has a good finish with no variation in hanging position, and can economically produce cushions that are comfortable to use. I will provide a.

[Means to solve the problem]

The hanging member used for hanging the cushion cover according to the present invention is a hanging cotton cloth sewn to the back side of the cushion cover along the design lines of the cover, which is inserted into the groove of the cushion pad and locked in the cushion loom. , comprising a mounting part integrally formed of a flexible synthetic resin material having elasticity and flexibility, and a plurality of anchor parts, the mounting part having a predetermined width for sewing the hanging cotton cloth. A sutured portion formed on a thin strip-shaped plate, a flexible metal wire formed on one side edge of the sutured portion, and the synthetic resin material coated and tightly attached to the peripheral surface of the wire with the wire as a core. and a straight cylindrical portion, each of the anchor portions being spaced apart from each other in the longitudinal direction of the attachment portion and located approximately in the same plane as the attachment portion. A rectangular plate-shaped connecting portion having the same thickness as the sutured portion is connected to the cylindrical portion, and a locking body is connected to the other end of the connecting portion, and the locking body is connected to the sutured portion. An upper anchor body of a columnar body connected to a connecting part and having approximately the same length as the connecting part, a lower anchor body of the columnar body arranged opposite to the upper anchor body, and these upper anchor bodies. and two narrow anchor body connecting portions that connect the lower anchor body near both ends thereof to form a substantially rectangular frame shape, and the upper anchor is attached to both ends of the lower anchor body. Anchor claws that are directed toward the body side and expand outward are formed protrudingly on the outside of the anchor body connecting portions, and the upper anchor body has flexible hooks that are directed toward the body side and expand outward. A structure is provided in which elastic locking pawls are provided protrudingly provided on the outside of the anchor body connecting portions.

[Effect]

When attaching the hanging member to the cover, the hanging cotton cloth interposed between the hanging member and the cover is overlapped with the attachment part of the hanging member, and the hanging cotton cloth and the hanging member are sewn and fixed along the suture line. Then, the upper end of the hanging cotton fabric is sewn along the design lines of the cover.

Next, the locking body of the anchor body, which hangs down from the lower end of the attachment via the connecting part, is pulled into the pad hole and the frame hole, which are previously drilled in the pad and frame at intervals of the hanging points of the cover. At this time, the lower anchor body and the left and right anchor claws of the locking body are elastically deformed inward in accordance with the frame hole diameter, and protrude through the frame hole. As the lower anchor body deforms, the anchor body connecting part also elastically deforms and moves through the frame hole, but the locking pawl of the upper anchor part that expands outward toward the lower anchor body hits the frame. . When the pulling force is removed, the deformation of the anchor body connecting part, lower anchor body, and anchor pawl immediately restores its original shape, and the elasticity of the locking pawl brings the anchor pawl into contact with the lower surface of the frame, causing the locking body to move into the pad hole and frame hole. Lock it in the frame hole while it is pulled in. Then, the hanging work is completed in which the cover fixed via the hanging cotton cloth, the pad and frame locked by the locking body are integrated with the hanging member.

FIG. 2 is a plan view illustrating an embodiment of the hanging member of the present invention, with a portion of the paper partially cut out in the left and right direction. FIG. 3 shows its side view.

A hanging member 1 generally designated by the reference numeral 1 includes a mounting portion 2 made of a narrow band-shaped thin plate, and a mounting portion 2 that is perpendicular to the longitudinal direction of the mounting portion 2 at an appropriate interval on one side edge of the mounting portion 2. It also consists of a plurality of anchor parts 3 arranged in a row in substantially the same plane as the mounting part 2, and is integrally made of a highly elastic and flexible synthetic resin material such as vinyl chloride, nylon, polypropylene, etc. molded.

The attachment part 2, which is a band-shaped plate-like body formed to have approximately the same width, has a highly elastic and flexible metal wire 4 on one side edge to which the anchor part 3 is connected, and the wire 4 as a core. It consists of a base 5 consisting of a straight cylindrical part 41 whose peripheral surface is closely covered with the synthetic resin material, and a plate-shaped suture part 6 connected to the cylindrical part 41 of the base 5, and the suture A thin suture line 7 is formed approximately in the widthwise center of the portion 6 in parallel with the four wires in the longitudinal direction of the suture portion 6 to form linear grooves on both surfaces.

Anchor parts 3 which are arranged in series at appropriate intervals in the longitudinal direction of the mounting part 2 are made up of a rectangular plate-shaped connecting part 8 and a locking body 9 having approximately the same thickness as the sewing part 6. The anchor portion 2 is formed to have a length corresponding to the length of the design line A shown in FIG. They are formed at intervals of location B.

The connecting portion 8 is integrally connected with the cylindrical portion 41 of the attaching portion 2 by forming a hinge portion 43 between one end edge thereof and the cylindrical portion 41 of the attaching portion 2 so as to be in substantially the same plane as the suture portion 6 of the attaching portion 2. The other end edge farther from the mounting portion 2 is connected to the locking body 9. The locking body 9 includes an upper anchor body 11 integrally connected to the connecting portion 8, a lower anchor body 13 disposed opposite to the upper anchor body 11, and the upper anchor body 11 and the lower anchor body 13. A pair of anchor body connecting parts 1 that connect the two near both ends of the
4, it is formed into a substantially rectangular frame shape. The upper anchor body 11 is a columnar body having a length that is the same as the width of the connecting portion 8, and has a lower anchor body at each end thereof in a plane in which the attachment portion 2 extends from both ends of the upper anchor body 11. Directed towards the 13th side,
and a short anchor claw 42 that expands outward and has a width that is approximately the same as the width of the upper anchor body 11;
42 is formed, and at the free end of each anchor claw 42, 42, a locking claw 1 which is narrower and more elastic than the anchor claw 42 in the extending direction of the anchor claw 4 is formed.
0 is formed. The lower anchor body 13 is a short columnar body parallel to the upper anchor body 11, and has anchor claws 1 at both ends thereof, which are directed toward the anchor claw 42 side of the upper anchor body 11 and expand outward.
2 are integrally formed. This anchor claw 12
The width is approximately the same as the width of the upper anchor body 11 and the lower anchor body 13, and the rigidity is greater than that of the anchor pawl 42 of the upper anchor body 11. The two anchor body connecting parts 14 are arranged parallel to each other, and one end of each is connected to approximately the tip of the anchor claw 42 of the upper anchor body 11 to make the locking claw 10 free,
The other end is connected to a substantially central portion of the anchor claw 12 of the lower anchor claw 13, causing the free end of the anchor claw 12 to protrude outside the anchor body connecting portion.
The width of the anchor body connecting part 14 in the plane in which the attachment part 2 extends is narrower than the width of the upper anchor body 11 and the lower anchor body 13, and its rigidity is equal to the rigidity of these anchor bodies 11, 13. Although the width is lower than that of the locking claw 10, the width thereof is larger than that of the locking claw 10, and the rigidity thereof is higher than that of the locking claw 10. As is clear from FIG. 3, the width (thickness) of each portion of the anchor portion 3 constituting the locking body 9 in a plane perpendicular to the plane in which the plate-shaped attachment portion 2 extends is as follows: It is formed to have a thickness several times the thickness of the suture part 6 of the attachment part 2 and the connecting body 3 of the anchor part 3, and the connecting part 8 is formed at approximately the center of the upper anchor body 11 in the thickness direction. A hinge portion 15 is formed at the portion to be integrally connected.

Locking body 9 of anchor portion 3 having the above configuration
is smaller than the dimension corresponding to the distance from the free end of one anchor claw 12 of the lower anchor body 13 to the free end of the other anchor claw 12 of the lower anchor body 13 in its free state, and between the outer surfaces of the anchor body connecting portion 14. When a plate material with a hole slightly larger than the size is prepared, the lower anchor body 13 is pulled into the hole by grasping the lower anchor body 13 at approximately the center, and the lower anchor body 13 has its elasticity. The anchor claw 12 is bent in the direction of bringing the free ends closer to each other and passes from the first surface to the second surface of the plate material, and after passing, the anchor claw 12 is restored to its original shape due to its elasticity and the anchor claw 12 returns to the second surface. On the other hand, the locking claw 10, which extends in the direction of extension of the free end of the anchor claw 42 of the upper anchor body 11, has its tip elastically abutting against the first surface of the plate-like material. It is clear that the locking body 9 is now locked to the plate-like material.

Next, a method of using the hanging member 1 having the above configuration will be explained.

Figure 4 is an explanatory diagram of the suspended state, Figures 5 and 6,
FIG. 7 is a cross-sectional view of the hanging portion along the design line A according to the state of use.

The hanging member 1 is attached to a hanging cotton cloth 21 for connecting to the cover 20. The hanging cotton cloth 21 is the hanging member 1
The material used is a band-like cloth having a width corresponding to the depth of a groove (described later) provided in a pad inside the cushion having the same length as the longitudinal length of the cushion, and having flexibility against bending.

The lower end of the hanging cotton cloth 21 is aligned with the upper step part 22 of the cylindrical part 41 of the base part 5 of the hanging member 1, and the two are sewn together along the seam line 7. The upper end of the hanging cotton cloth 21 with the hanging member 1 is sewn together with the cover 20 along the design line A of the cover 20.
The hanging member 1 is suspended on the inner surface of the design line A of 0.

The cushion has a triple structure in which a cover 20 is stacked on the top surface of a pad 23 having a thickness of _C1 , and a frame 24 is stacked on the bottom surface. A groove 25 is provided in the pad 23 at a position corresponding to the design line A of the cover 20. Groove 2
The depth of 5 is approximately the width (length) from the attachment part 2 of the hanging member 1 integrated with the hanging cotton cloth 21 to the cover 20.
C equals ₂ .

A pad hole 2 passing through the frame 24 is provided in the groove 25 at a location where the hanging member 1 is connected to the anchor portion 3.
Drill 6. The pad hole 26 is a cylindrical hole large enough to allow the anchor portion 3 of the hanging member 1 to pass through, and the frame hole 27 formed in the frame 24 at the lower end of the pad hole 26 is connected to the connecting portion 8 of the anchor portion 3 and the anchor body connecting portion. It is a round hole whose diameter is the width dimension of the portion 14. Then, a frame locking portion 28 having a different size between the pad hole 26 having a slightly larger diameter and the frame hole 27 having a slightly smaller diameter than the pad hole 26 is formed in this portion.

The groove 25 of the pad 23 having such a structure is aligned with the hanging member 1 fixed to the hanging cotton cloth 21 hanging down along the design line A of the cover 20, and the anchor part 3 is inserted into the pad hole 26. Since the depth of the groove 25 is equal to the width C 2 of the attachment part 2 of the hanging member 1 with the hanging cotton cloth ₂₁ attached, the lower end of the base 5 with the wire 4 as the core of the hanging member 1 in the groove 25 is at the bottom of the groove 25. It will now rest on the pad surface. Then, the anchor part 3 is inserted into the pad hole 26, and the locking body 9 is pulled out from the frame hole 27. At this time, the lower anchor body 13 and the anchor claws 12 at both ends are elastically deformed inwardly according to the diameter of the frame hole 27 due to their elasticity and flexibility, and pass through the frame hole 27 and protrude outward. Lower anchor body 13 and anchor claw 12
Due to the deformation of the anchor body connecting portion 14 of the rectangular side frames
The anchor portion 3 is also elastically deformed inward, and the anchor portion 3 is inserted through the frame hole 27 (see FIG. 6). This locking part 9
The insertion operation does not require a large force because the lower anchor body 13 and the anchor body connecting portion 14 are elastically deformed.

After the anchor part 3 is drawn into the frame hole 27, the anchor body connecting part 14, the lower anchor body 1
3 and the anchor claws 12 quickly return to the rectangular frame body, and the anchor claws 12 are locked to the lower surface of the frame locking portion 28, as shown in FIG. On the other hand, the locking pawl 10 of the upper anchor body 11 elastically abuts the upper surface of the frame locking part 28, and the locking body 9 locks with the frame locking part 28. In this state, the hanging member 1 suspends the cover 20 via the hanging cotton cloth 21. In this way, each anchor part 3 is locked in the frame hole 27, and the hanging cotton cloth 21 is attached along the design line A of the cover 20.
Hanging points are formed at appropriate intervals through the

A case in which a load is applied to the cushion constructed in this manner will be described with reference to FIG.

When a small load is applied, the hanging cotton cloth 21 bends and the bending portion 29 responds to the load.

When a load cannot be handled by the bending of the hanging cotton cloth 21, for example, when the pad at the position shown by the two-dot chain line in FIG. 7 bends to the position shown by the solid line, the connecting portion 8 of the hanging member 1 bends (see symbol 3 in FIG. 7).
At this time, the locking claws 10 of the locking body 9 slide on the upper surface of the frame locking portion 28, and their movement is restricted by the wall surface of the pad hole 26, preventing the locking body 9 from protruding outward beyond a certain extent.
0. The anchor claws 12 are made of a synthetic resin material having elastic flexibility, so that no abnormal noise is generated between the frame 24 and the cushion when the suspension member moves up and down due to bending of the cushion.

Although this embodiment describes the case where it is used for a vehicle cushion, the hanging member of the present invention can also be used for hanging furniture, office chairs, etc. There is no difference in its ability, action, or effect.

Note that in this embodiment, the locking body 9 of the anchor portion 3
The lower anchor body 13 has been described as having a linear columnar body in the center and anchor claws 12, which are similar linear columnar bodies, integrally formed at both ends of the lower anchor body 13. It is clear that the entirety of the anchor claw 12, including the anchor claw 12, may be formed into an arc shape. Further, when the anchor claws 42 of the upper anchor body 11 of the locking body 9 are made to appropriately protrude outside the anchor body connecting portions 14, 14, the locking body 9 is inserted into the frame hole 24 of the frame 24.
There is no escape from 7.

The hanging member according to the present invention can be integrally molded using an injection molding in which the split surface of the mold is split into one plane, and has a configuration that can reduce costs.

[Effect of idea]

Since the hanging member according to the present invention is integrally molded from a synthetic resin having elasticity and flexibility, it is easy and economical to manufacture, is flexible in response to external forces, and has excellent restoring force.

When using the hanging member, the hanging point can be formed by simply pulling out the locking body of the anchor part of the hanging member attached to the hanging cotton cloth sewn to the cover from the frame hole, which saves the traditional lifting work. As this does not depend on experience, no skill is required, and the lifting work can be done easily and quickly.

In addition, the positions of the anchor part, pad hole, and frame hole of the hanging member are determined and preset according to the location where the cover is hung, so there is no misalignment of the cover, pad, and frame, and the finished quality of the cushion is improved. improves.

Furthermore, since the anchor part of the hanging member is inserted directly into the frame hole for hanging, there is no need for insert wires or resin nets for hanging inside the pad, reducing the cost of wires and resin nets.
This reduces insert man-hours. Since the hanging member is sewn and fixed to the hanging cotton cloth in advance, the sewing work is easy and the hanging cotton cloth and the hanging member can be reliably and easily positioned using the suture line and the base as reference lines.

Loads caused by the passenger's weight, etc. can be dealt with by bending the connecting part and protruding the locking body, and the suspension member does not feel like a foreign body or hitting the bottom. No sliding noise is produced between the two.
