Description

[Detailed explanation of the invention] This invention is a net pocket that can be placed on the back of the seat back of passenger cars, sightseeing buses, railway vehicles, aircraft, etc., on the door trim of passenger cars, on the walls of trunk rooms, etc.
The installation in Figure 1) relates to the frame.

First, the conventional one will be explained with reference to Fig. 7.
The frame 1, which is generally approximately U-shaped and has an open upper side, is made by injection molding of synthetic resin or by bending thick wire or thin metal pipe.

On the other hand, a net N having an outer shape and size approximately matching the overall outer shape and size of the frame 1 is hand-knitted.

Then, by sequentially inserting the nets along the other three sides of the net N from the one white end side of the frame body 1, excluding the upper side opposite to the frame open side of the net N, a net Nikkei along the three sides of the net (or string) N□ is tied around the outside of the corresponding side of the frame to make the net N stretched within the frame body surface.

Reference numeral 5 denotes a rubber cord which is stretched between the free ends of the frame 1 through each mesh of the net along the upper side of the net N to close the opening of the pocket.

The frame body 1 covered with the net N is then fixed to the back surface of the seat back using screws, stab legs, or the like.

Reference numeral 11 denotes projecting pieces for screw insertion, which are formed in advance at key points on the frame 1 for screwing the frame 1.

However, in the above-mentioned conventional net pocket, (1) the net tension for frame 1 is
This work is inherently inefficient as it involves sequentially inserting the mesh along the three sides of the frame 1, and in reality, the frame 1 has several protrusions 11 as described above along the frame. Since the frame-fixing piercing legs 12 as shown in FIGS. 1-2 are formed in a protruding manner, each of them serves as a hindrance to the sunlight passing through the net, resulting in even worse efficiency.

(2) Correspondence of net N to each side of frame 1 Since the net Japanese on each side is entwined with the outside of frame 1, it looks unsightly, and it is difficult to attach frame 1 to the body. When attached to the frame 1, a net thread is interposed between the back surface of the frame 1 and the body surface of the object to which it is attached, so that the back surface of the frame 1 does not come into close contact with the object's body surface and floats, and the gap caused by the floating is covered by the net thread. Or, the thicker the string, the bigger it is, which also makes it unsightly.

(3) For the net N, only a hand-knitted net that has been prepared in advance to have an external shape and size approximately matching the overall external shape and size of the frame 1 can be used.

In the case where a wide net made by machine knitting with a lid is cut to match the overall external shape and size of the frame 1, the net stitches #J2 (knot knots of the net threads) along each cut side are shown in Figure 7. This is because, as shown by the chain line, it will form along the frame 1, resulting in an extremely unsightly appearance.

The purpose of this project is to eliminate all of the drawbacks and problems of the conventional net pockets as described above.As shown in Figures 2 to 6, grooves 2 are provided along the length of the back of the frame 1, A plurality of notches 3 for net hooking are provided at approximately equal intervals along the length of the inner side wall of the groove frame, and the cutouts 3 are formed at approximately the same length as the groove 2 to be embedded in the groove 2. The hook is equipped with a rod member 4 for holding down the net, and the net pocket is attached using a frame.

The illustrated frame 1 is formed into a U-shape overall by the Hewei resin injection molding method, but the planar shape of the frame may be arbitrary, such as a semicircular arc with the upper side open.

The grooves 2 were formed along the length on the back surface of each side of the frame 1.

The rod members 4 to be fitted into the grooves 2 were made by extrusion molding a synthetic resin into a rectangular shape in cross section and cutting the rods to match the lengths of the grooves 2 on each frame side.

Reference numeral 12 denotes piercing legs for fixing the frame body, which are protruded from key points on the back surface of the frame 1.

In terms of usage, net N can be hand-knitted with a shape and size that roughly matches the overall external shape and size of frame 1, or a machine-knitted wide net can be used as frame 1. Cut the net to the required shape and size, and cut each thread N of the net mesh along the other three sides excluding the top edge of the net N.
1 center portions are respectively hooked onto corresponding notches 3 provided longitudinally in the groove side walls on the inner side of the frame on each side corresponding to the frame 1 side.

As a result, the net N becomes stretched within the plane of the frame.

Next, each hook of the frame 1 is hooked to the part 3 and rotated into the groove 2 by fitting the cross-sectional bar 4 into the groove 2 on each side of the frame as shown in Figure 4.5. The center portion of each of the net white threads N□ is pressed down and prevented from coming off by the bar 4 that is fitted into the groove 2 later.

Then, the back side of the frame 1 on which the net N is stretched is placed so that the back side of the frame 1 faces the surface of the member to be attached, such as the back of the seat back, and the legs 12 for fixing are provided in advance so as to correspond to the side of the member to be attached. The frame is fixed by fitting it into the receiving hole and pressing it until the back side of the frame is in close contact with the surface of the member to be attached.

When the frame 1 is provided with screw insertion lugs 11 as shown in FIG. 7, the screws are inserted into the holes of the lugs 11 to fix the frame 1 to the surface of the member to be attached.

Reference numeral 5 denotes a pocket opening closing rubber cord similar to that shown in FIG.

As mentioned above, (4) A groove 2 is provided along the longitudinal direction on the back side of the frame 1, and the groove 2 is
A plurality of notches 3 for net white thread hooking are provided at approximately equal intervals along the length of the inner side wall of the frame, and each of the notches 3
This method involves hooking the center part of the individual net white threads along the other three sides excluding the top edge of the net N and stretching the net over the frame 1, so the conventional net Nikkei along the other three sides excluding the top edge in Figure 7 The net tensioning process can be performed more easily and quickly than in the case where the net N is sequentially inserted from one end of the frame 1 to the other end and the net N is finally stretched over the frame 1.

Moreover, since the net is not inserted through the frame, even if the frame 1 has lugs 11 and protruding legs 12 formed in a protruding manner, the netting process can be carried out quickly regardless of this.

(B) Each net hook on each side of the frame is hidden in the groove 2 on the back side of the frame, and cannot be seen from the outside when the net pocket is installed as shown in Figure 1. The appearance and appearance are better than the one in which the corresponding net Japanese N0 on each side of the product frame 1 appears to be intertwined.

In addition, each net hook on each side of the frame is prevented from coming off by an embedded rod member 4 fitted into the groove 2, and the rod member 4 can be attached to the frame 1 by fixing it to the surface of the member. Since the net N is directly pressed into the groove 2 by the member surface, the net N will never come out of the frame.

Since the back side of the frame 1 is firmly attached to the surface of the attached member without floating, the net pocket can be installed in a more stylish manner than the conventional product shown in FIG.

(Q: Even if a machine-cut piece is used as the net N, the appearance will be impaired because the individual net stock N2 along each side of the net cut will be hidden in the groove 2 as shown by the chain line in Figure 2. Therefore, machine-knitted nets that can be mass-produced at low cost can be used without any problems.

That is, all the drawbacks and defects (1) to (3) of the conventional products mentioned above.
This type of net pocket installation is effective and appropriate as an improvement to the frame.

2□ is a recessed arc portion formed by recessing the inner surface of the side wall opposite to the side wall where each net hook of the groove 2 forms the notch portion 3 at a position corresponding to each notch portion 3. As a result, the width of the groove 2 in the notch 3 for each net hook becomes wider, and the net N
When a machine-knitted cut material is used, it can be easily inserted into the individual net #J2 grooves 2 along each side of the net (dashed line in Fig. 2).

In this case, the vertical side of the L-shaped rod member 4 fitted into the groove 2 at the position corresponding to the net daily storage N2 position is bent along the concave arc portion 2 □ against elasticity as shown in Figure 6. Due to the reaction force of the deflection, the net white eyebrow N2 is strongly pressed between the deflected vertical side portion and the inner surface of the groove side wall on the side where the notch 3 is formed. The net is firmly prevented from coming off.

2 □ is formed in the groove 2 at key points along the side wall on which the notch 3 is formed, in order to stably fit and hold the cross-sectional rod member 4 in the groove 2. L-shaped bar member 4
The horizontal one bottom support is a stop protrusion.

The rod member 4 is not limited to the illustrated cross-sectional shape, but may have any shape, such as circular, rectangular, or U-shaped in cross-section, as long as the net hook fits into the groove 2 in an embedded manner. do not have.

Moreover, it may be either hard or soft, for example, it may be an elastic soft string-like material such as rubber.
