As a result, the back plate 6 is held so that it cannot be detached upward.

(3). Connection structure Next, mainly with reference to FIGS. 7 and 8, the connection structure of the main members 11 and the top member 12, and, illustrating the relation between the top member 12 and the back support 7. As shown in FIG. 8B, the upper end of the main member 11 and the upper end of the back support 7 are provided with rearward projecting portions 42 and 43 that overlap in the front and rear and have the same upper surface. A positioning hole 44 opens vertically in the rearward projecting portion.

On the other hand, the top member 12 has an intermediate step portion 45 that overlaps with the main member 11 and the rearward protruding portions 42 and 43 of the back support 7 in a plan view, and the intermediate step portion 45 has a positioning hole 44 in the main member 11. A positioning projection 46 to be fitted is provided. The intermediate step portion 45 is also provided with a rib 47 that contacts the rearward projecting portions 42 and 43 from above. The overhang portion 13 of the top member 12 has a downward projecting portion 13 a that projects downward from the intermediate step portion 45. Downwardly extending portion 13a extends over the left and right full length of the overhang portion 13, the front of the downwardly extending portion 13a, is empty upper space open to the lower left and right sides.

As shown in FIGS. 8A and 4A, a guide rib 48 connected to the intermediate step portion 45 and the downward projecting portion 13a is provided inside the left and right positioning projections 46 of the top member 12. . The front surface of the guide rib 48 is inclined so as to be inclined forward with respect to the vertical line in a side view, and the guide rib 48 is located behind the inner frame portion 37 in the back support 7 in a state where the backrest 3 is assembled. .

And, when the assembly of the backrest 3, as shown in FIG. 2 (C) and FIG. 3, the back plate 6 which is configured by mounting the top members 12 to the main member 11, and root weight from above the back support 7 At the time of attachment, when the overhang portion 13 of the top member 12 is moved down so as to overlap the back support 7, the guide rib 48 hits the rear surface of the inner frame portion 37 of the back support 7, so that the back plate 6 When the back plate 6 is moved downward and overlapped with the support 7, the positioning projection 46 is fitted into the positioning hole 44 and the upper and lower engagement bodies 29, 32 are engaged with the engagement receiving portions 30, 32. To fit.

When the upper and lower engagement bodies 29 and 32 are not fitted to the engagement receiving portions 30 and 32, when the main member 11 is pressed backward , the engagement claws 29a and 32a of the upper and lower engagement bodies 29 and 32 are elastically deformed. Thus , the engagement receiving portions 30 and 32 are engaged. For example, as shown in FIG. 8 (A), the left and right side portions of the top member 12 are formed with downward protrusions 49 continuous with the protrusions 18, while the upper ends of the protrusions 18 in the main member 11 are open upward. The downward projection 49 is fitted to the cylindrical portion 50.

For example, as clearly shown in FIG. 3, ear portions 51 that fit into the side recesses 14 of the top member 12 are provided at both left and right ends of the upper end portion of the back support 7. Top member 12, two are prepared with low height type and high type, if the height using a higher top member 12, as shown in FIG. 3, for blindfold ears 51 mounting the plug 52. Note that for standby those three or more height as the top member 12, it is also possible to use arbitrarily selected.

(4). Hanger device will now be described hanger device 16 with reference mainly to Figure 9 following figures (The back support 7 shown in FIG. 10, prior to the back support 7 shown in FIGS. 4 to 6 The top shape as seen from is slightly different, but they are essentially the same). For example, as shown in FIG. 9B, the hanger device 16 includes a base bracket 54 held between the back support 7 and the top member 12, a holder 55 attached to the base bracket 54, and a height higher than the holder 55. And a hanger body 56 attached to be adjustable. Details will be described below.

For example, as shown in FIG. 11, the base bracket 54 includes an upper plate 54 a that overlaps the rearward projecting portion 43 of the back support 7 from above, a vertical portion 54 b that is positioned behind the rearward projecting portion 43 of the back support 7, and a vertical portion. The lower plate 54c protrudes backward from the lower end of 54b, and has a hanger receiving portion 54d protruding upward from the rear end of the lower plate 54c. Shape). The hanger receiving portion 54d and the hanger body 16 are arranged in a state of being separated behind the overhang portion 13. The front plate 54a, the vertical portion 54b, and the lower plate 54c constitute a front portion of the base bracket 54, and this front portion is in a posture that crosses the upper space of the top member 12. The vertical portion 54b is an upright portion when viewed from the lower plate 54c.

A left and right horizontally long rod 57 is fixed to the upper plate 54a of the base bracket 54 by welding, and a pair of hooks 58 facing forward in a side view in which the rod 57 is fitted from the front are formed on the rearward projecting portion 43 of the back support 7. Projecting upwards one by one. In addition, a horizontally long vane plate 59 that is overlapped with the back surface of the rearward protruding portion 43 of the back support 7 is welded to the front surface of the vertical portion 54 b of the base bracket 54. The rod 57 is bent in a forward concave shape (or rearward convex shape) in a plan view, and thus has excellent stability. An upward lip is bent at the front end of the upper plate 54 a of the base bracket 54 in order to hold the rod 57 firmly.

The rearwardly projecting portion 43 of the back support 7 is provided with a frame portion (recess) 60 in which the left and right end portions of the blade plate 59 are fitted so as not to move left and right and up and down. The base bracket 54, the rod 57, and the blade plate 59 can be collectively referred to as a base portion. The base bracket 54 is attached to the back support 7 with the back plate 6 removed. That is, back in the posture inclined in side view as the hanger receiving portion 57d is at the top, the first rod 57 placed because fitted from the front to the hook piece 58, then returned to a predetermined position, a very simple procedure of Attached to the support 7.

The base bracket 54 is held so that it cannot be displaced in the front-rear direction , the left-right direction, and the upper-lower direction. A rib 61 that projects the upper plate 54a of the base bracket 54 so that it cannot be displaced left and right is projected upward from the rearward projecting portion 43 of the back support 7. Further, as shown in FIG. 14, a pair of left and right holding ribs 62 that are in contact with or in close contact with the vertical portion 54 b of the base bracket 54 are provided inside the top member 12 constituting the back plate 6 (see FIG. 14). 4 (A) and FIG. 8). For this reason, the hanger device 16 is held so as not to fall forward.

If the left and right horizontally long rods 57 and the blades 59 are fixed to the base bracket 54 as in the present embodiment, there is an advantage that stability can be improved. In addition, the frame part 60 of the left and right ends and the back support 7 of the blade plate 59 is provided with a round hole 63a, 63b which communicate with each other. When it is desired to obtain a higher fastening strength, it is possible to fasten with screws using the round holes 63a and 63b (the screws may be screwed into the blade plate 59 from the front, or the pocket in front of the frame portion 60). It may be screwed into the nut attached to the part from behind.)

  For example, as shown in FIG. 13, the holder 55 includes a holder main body 64 attached to the hanger receiving portion 54 d of the base bracket 54 and a stopper 65 attached to the holder main body 64 from the front. Both are resin molded products. As shown in FIGS. 13C and 14, the front portion of the holder main body 64 includes upper and lower front frame portions 66 that overlap the hanger receiving portion 54d of the base bracket 54, and a hanger receiving portion 54d of the base bracket 54. The holder main body 64 has a top plate 68 that comes into contact with the hanger receiving portion 54d of the base bracket 54 from above.

Further, as shown in FIG. 14, while the lower portion of the hanger receiving portion 54d of the base bracket 54 is provided with a front view rectangular engaging holes 70, the holder body 64, fitted strut from below the engaging hole 70 An engaging claw 71 is provided to hold the holder 55 so that the holder 55 cannot be pulled upward. Engagement claw 71 is inclined in a state deviated ago go on, Therefore, when fitted from above the holder body 64 in the hanger receiving portion 54d, the engaging claw 71 is once to fall behind After being deformed, it is returned and deformed to fit into the engagement hole 70.

  As can be understood from FIG. 14, the upper and lower front frame portions 66, the rear frame portion 67, and the engaging claws 71 of the holder main body 64 are shifted in the vertical direction and do not overlap when viewed from the front-rear direction. In other words, the space between the upper and lower front frame portions 66 and the lower portion of the lower front frame portion 66 are open. This is for facilitating the die-cutting in manufacturing the holder main body 64 using a mold that relatively moves in the left-right direction in the state of FIG.

For example, as shown in FIG. 14, the rear surface portion of the holder main body 64 constituting the holder 55 is provided with a plurality of eaves portions 72 projecting left and right in plan view, while the hanger body 56 has a foot portion 56a. It is formed in a T shape when viewed from the front, and is provided with a dovetail groove 73 that fits into the heel portion 72 of the holder main body 64 in the foot portion 56a. For this reason, the hanger body 56 is attached to the holder 55 in a state in which it cannot move back and forth and only moves up and down. The left and right dovetails 73 are continuous. For this reason, a concave groove 74 having a forward opening is opened in the foot portion 56a.

For example, as shown in FIGS. 13A and 13B, the engaging claws 75 projecting forward are provided on the left and right sides of the stopper 65, while the engaging claws 75 are fitted on the holder body 64. A mating engagement hole 76 is provided. Therefore, the stopper 65 can be attached to the holder body 64 simply by pressing. Further, a rubber 77 (see also FIG. 14) is interposed between the holder main body 64 and the stopper 65 as an example of an elastic body. For this reason, the stopper 65 is urged rearward. Further, a flap 78 that fits into the dovetail 73 of the hanger body 56 is provided on the stopper 65 so as to protrude outward in the left-right direction.

As shown in FIG. 13A and FIG. 14, the recessed groove 74 of the foot portion 56 a in the hanger body 56 has a raised position restricting projection 79 that restricts the vertical height of the hanger body 56 and the hanger body 56 at the upper height position. A retaining protrusion 80 is provided to be separated from the top and bottom. On the other hand, the rear surface of the stopper 65 is provided with an upper protrusion 81 that can come into contact with the raised position restricting protrusion 79 from below and a lower protrusion 82 that can come into contact with the retaining protrusion 76 from below.

The raised position restricting protrusion 79 of the stopper 65 and the upper protrusion 81 of the hanger body 56 have a mountain shape that is inclined on both the upper and lower surfaces in a side view. On the other hand, the retaining protrusion 80 is inclined at the lower surface but the upper surface is substantially horizontal, and the lower protrusion 82 of the stopper 65 is inclined at the upper surface but is substantially horizontal at the lower surface. Yes.

FIG. 14 illustrates a state in which the hanger body 56 is lowered. In this state, the hanger body 56 is held so as not to be lowered by the upper end of the recessed groove 74 abutting against the upper end of the holder body 54. On the other hand, when the hanger body 56 is pulled upward, the upper protrusion 81 of the hanger body 56 pushes the stopper 65 forward against the elasticity of the rubber 77, thereby preventing the retaining protrusion 76 of the stopper 65 and the raised position restricting protrusion. Overcoming 79.
