Description

The present invention relates to a padded member constituting a chair and an armrest as an example thereof. Examples of the padded member include a headrest and a shoulder rest.

It is common practice to provide armrests in chairs. There are various structures of armrests, but it is also widely practiced that the part where the elbow hits is composed of an elbow pad made of a soft material. There are various mounting structures for the elbow pad, and Patent Document 1 discloses that the elbow pad is fixed to the armrest receiver with four screws in the elevating armrest. That is, the elbow pad is fixed to the armrest receiver by forming four female screw holes that open downward in the elbow pad and screwing a screw inserted into the armrest receiver from below into the female screw hole.

Further, in Patent Document 2, while a large number of cylindrical bosses are formed on the upper surface of the armrest receiver, an insertion plug to be fitted into the boss is provided on the lower surface of the elbow pad so that the insertion plug cannot be pulled out from the boss. Press-fitting is disclosed. In Patent Document 2, the insertion plug is formed in a serrated cross section so that it can be driven but cannot be removed.

On the other hand, in Patent Document 3, the upper half of the elbow strut made of a round pipe is formed in an inclined portion whose height becomes lower toward the front, while the elbow pad also has the front portion as an inclined portion for lateral view. In the case of forming a dogleg shape, a screw cylinder that protrudes backward from the inclined part of the elbow pad is penetrated through the inclined part of the elbow strut, and a screw that penetrates from behind through the inclined part of the elbow strut is screwed into the screw cylinder while elbowing. It is disclosed that the rear end of the pad is provided with a downward end face portion that overlaps the rear surface of the elbow strut, and the end face portion is provided with a protrusion that fits into the rear end of the horizontal portion of the elbow strut.

That is, in Patent Document 3, since the rear end portion of the elbow pad is held immovably up, down, left and right by the protrusion, the elbow pad is attached to the elbow receiving portion by one screw so as not to be detached.

Using a screw as a fixing means as in Patent Document 1 has an advantage that the elbow pad can be firmly fixed to the elbow receiving portion. However, since four screws are used in Patent Document 1, screwing work of the screw is required. There is a problem that it is troublesome and the workability of assembly is poor.

On the other hand, in Patent Document 2, the pad is attached by strongly pressing the elbow pad against the elbow receiving portion, but since the elbow pad must be strongly pressed, if it is a manual work, the burden on the operator is only heavy. However, there is a problem that the ease of installation and the disengagement prevention function conflict with each other.

On the other hand, in Patent Document 3, since the horizontal displacement is prevented by the end face portion of the rear end and the protrusion, there is an advantage that the fastening can be firmly performed with only one screw. However, in Patent Document 3, since it is necessary to form an inclined portion between the elbow receiving portion and the elbow pad, it cannot be applied to an armrest having a flat upper surface, and therefore there is a problem that it lacks versatility.

The invention of the present application was made in the wake of such a situation.

The present invention includes various configurations, and typical examples thereof are specified in claims 1 to 5. Of these, the chair according to the invention of claim 1 is intended for a padded member, and the present invention is based on the present invention.
"It has a receiving part as a strength member and a pad mounted on the surface of the receiving part.
An engaging portion is formed at one end of the pad and one end of the receiving portion so as to be fitted by shifting the pad toward the surface thereof and to hold the pad inseparably from the receiving portion. "
In the basic configuration
"The engaging portion of the receiving portion is composed of an engaging member separate from the receiving portion and is fixed to the receiving portion, and the pad is fastenerd or elastic at a portion away from the one end portion. It is fixed to the receiving part by an engaging means using deformation. "
The configuration is added. As the fastener, a clip that elastically deforms can be used in addition to the screw. An example of an engaging means utilizing elastic deformation is an engaging claw.

Claim 2 embodies claim 1.
"The engaging member is an engaging metal plate made of a metal plate, and a base piece fixed to the receiving portion by a screw, an engaging piece into which the pad-side engaging portion fits, and the engaging piece and the base. It consists of an intermediate piece that connects the pieces. "
It is configured as.

The invention of claim 3 is an application of claim 2 to an armrest.
"The receiving portion is an anterior-posterior longitudinal elbow receiving portion integrally molded with the backrest, and the pad is an anterior-posterior longitudinal elbow pad.
At the rear end of the elbow pad, an engaging hole as the pad-side engaging portion is opened in a substantially horizontal direction.
The engaging member is fixed to the rear end of the elbow receiving portion with a screw, and the engaging metal fitting includes a base piece fixed to the elbow receiving portion, an intermediate piece rising from the base piece, and the above. It consists of an engaging piece that protrudes horizontally from the intermediate piece. "
It is configured as.

The invention of claim 4 embodies claim 3.
"The elbow receiving portion and the rear end portion of the elbow pad are inwardly curved portions curved in a plan view toward the backrest, and the engaging hole is opened in the direction toward the backrest."
It is configured as.

The invention of claim 5 embodies claim 2 or 3.
"The outer peripheral portion of the elbow pad and the elbow receiving portion is held so as not to be laterally displaced by ribs and grooves that are fitted to each other, and the front end portion of the elbow pad is inserted into the elbow receiving portion from below. It is fixed with the screw of the book. "
It is configured as.

In the present invention, the engaging portion may be formed at only one place or at a plurality of places.

In the invention of claim 1, since one end of the pad is held by the engaging member so as not to be disengaged from the receiving portion, fastening with only one screw or the like or snap engagement using an elastically deformable engaging claw is used. The pad can be firmly fixed even by using a fixing means such as. Therefore, the pad can be attached efficiently and can be firmly fixed in a state where it does not come off from the receiving portion.

Since the engaging member is separate from the receiving portion, even if the receiving portion is an injection-molded product made of synthetic resin or a die-cast product such as aluminum, so-called undercutting is unnecessary and die-cutting can be easily performed. Can be manufactured in a state. Therefore, in claim 1, the pad can be firmly and efficiently fixed while the receiving portion can be easily manufactured. In addition, since one end of the pad does not rise from the receiving portion, the outer line of the pad is sharpened and the appearance is excellent.

The form of the engaging member can be arbitrarily set as needed, but if the engaging metal fitting made of a metal plate is used as in claim 2, it can be firmly fixed even though it is small.

The present invention can be widely applied to members provided with pads such as headrests and shoulder rests, but when applied to armrests as in claim 3, the true value of the present invention is strongly exhibited. In other words, since the armrest is easily subjected to external force such as being grasped by a person and peeled off, it is highly necessary to firmly fix the elbow pad so that it will not be peeled off from the elbow receiving part, and since it is long in the front and back, it is efficient. Moreover, it is highly necessary to firmly fix it, but by applying the present invention, these requirements are satisfied and the true value is strongly exhibited.

When the armrests are integrated into the backrest, the structure is simplified accordingly. In this case, since the armrests are arranged on the left and right outer sides of the seat in a plan view, if the rear end of the armrests is formed into an inwardly curved portion curved toward the backrest as in claim 4, the support area of the elbows is increased. It is possible to improve the support stability of the elbow.

In addition, the upper surface of the elbow pad and the side surface of the backrest are continuous to increase the unity and continuity between the armrest and the backrest, so that the design is unified and the appearance is excellent. Furthermore, since the rear end of the elbow pad is fixed to the elbow receiving portion via the engaging member, the end edge of the inwardly curved portion can be brought into contact with the side surface of the backrest without lifting. Therefore, the upper surface of the elbow pad and the side surface of the backrest appear to be continuous without a boundary, and a high aesthetic appearance can be maintained.

Now, a person may grab the back of the elbow pad and stand up, in which case the elbow pad may be lifted and the rear end of the elbow pad may be rolled up. When the configuration of 4 is adopted, first, the inwardly curved portion is formed on the elbow pad to make it difficult to deform, so that it is difficult to roll up (the rear end edge of the elbow pad is in a state of being stretched to the backrest). However, it is difficult to turn.)

In addition, since the engaging member is arranged at the inwardly curved portion, the inwardly curved portion having high rigidity is firmly connected to the elbow receiving portion, and as a result, it is rolled up. The prevention effect is further improved.

When the elbow pad and the elbow receiving portion are fitted over substantially the entire circumference as in claim 5, the elbow pad is held so as not to be laterally displaced, so that it is only caught by the engaging member and fixed by one screw. Even so, the elbow pad can be firmly fixed all around the circumference without turning over.

It is a figure which shows the chair of an embodiment, (A) is a perspective view seen from the front, (B) is a plan view. (A) is a front view and (B) is a side view. (A) is a view in which the pad is turned inside out, and (B) is a separated perspective view. (A) is a cross-sectional view of FIG. 3 (A) seen from the IVA-IVA viewing direction, (B) is a separated perspective view with the pad and the engaging member turned inside out, and (C) is a separated perspective view. .. It is a figure which shows another example of the engaging metal fittings.

(1). Basic structure of chair Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the chair includes a leg device 1, a seat 2, and a backrest 3, and an armrest 4 is provided on the left side of the backrest 3. The seat 2 can be flipped up and rotated with the portion near the rear end as a fulcrum.

The leg device 1 includes left and right front legs 5 tilted backward in side view, left and right rear legs 6 tilted forward in side view, and left and right longitudinal reinforcing frames 7 connecting the upper parts of the left and right front legs 5. It has a character-like shape when viewed from the left side (human character when viewed from the right side).

A caster 1a is attached to the lower ends of the legs 5 and 6. The front leg 5 and the rear leg 6 are integrally connected via a joint 8. As shown in FIGS. 1A and 2B, the upper end portion 6a of the rear leg 6 is exposed above the joint 8, and the upper end portion 6a of the rear leg 6 has the left and right end portions of the backrest 3. The boss portion 9 having a downward opening provided in the above is fitted and mounted.

The front and rear legs 5 and 6 and the reinforcing frame 7 are made of a metal pipe such as a steel pipe, and the joint 8 is a cast product using a metal such as aluminum, but a die-cast product or a resin molded product can also be used. The boss portion 9 is held and held by a screw on the upper portion 6a of the rear leg 6. Therefore, as shown in FIG. 3 (B), the screw insertion hole 10 is formed in the boss portion 9 so as to open backward.

For example, as shown in FIG. 1 (B), the left and right front legs 5 are arranged in a parallel posture in a plan view, while the left and right rear legs 6 are arranged in a posture in which the distance between them is widened toward the rear. Then, for example, as can be understood from FIG. 2A, the front legs 5 are arranged so as to be offset to the left and right inward from the rear legs 6. Then, the seat 2 is connected to the front leg 5 so that the seat 2 can be rotated upward with the portion near the rear end as a fulcrum, and when the seat 2 is flipped up and rotated upward, a plurality of chairs can be nested back and forth (). Can be fitted.).

The backrest 3 is a molded product of a synthetic resin such as polypropylene, and has a shape of a left-right length recessed forward in a plan view. Further, the backrest 3 basically has a plate-like shape, and the upper end portion is formed on the upper flange piece 3a that is curved backward. The upper flange piece 3a has a reinforcing function of the backrest 3, a handle function for moving the backrest 3, and a design function.

(2). Structure of the armrest For example, as shown in FIG. 3A, the armrest 4 is mounted on the elbow receiving portion 11 integrally formed on the right side portions 3b of the backrest 3 and the upper surface of the elbow receiving portion 11. It is composed of an elbow pad 12, and the boss portion 9 projects downward from the base portion of the elbow receiving portion 11. Since the hind legs 6 are in a forward leaning posture, the boss portion 9 is also in a forward leaning posture. The elbow pad 12 is made of an elastomer-based or soft synthetic resin-based material.

As shown in FIG. 1B, the armrest 4 has a long front and rear shape, and the front end portion 4a and the rear end portion 4b are formed in an arc shape. The armrest 4 is rounded in the anterior-posterior length and slightly increases in width toward the rear, but is slightly inclined in a plan view so as to approach the backrest 3 toward the rear.

Further, since the elbow receiving portion 11 has a certain amount of front-rear thickness, for example, as can be understood from FIG. 4C, the left and right side portions 3b of the backrest 3 where the elbow receiving portion 11 is continuous is the elbow receiving portion 11. The thickness of the left and right side surfaces 3c of the backrest 3 gradually decreases from the connecting portion with the elbow receiving portion 11 to the upper side while the thickness changes smoothly so as to become thicker toward the elbow.

The armrest 4 of the present embodiment is also larger in lateral width and front-rear length than the conventional product. The chair of this embodiment is a simple type that can be nested, which is often used in lecture halls, etc., but although it is a simple type chair, the armrest 4 is large and has a high-class specification with an elbow pad 12.

The left-right width of the backrest 3 is substantially the same as the left-right width of the seat 2, while the armrest 4 is located on the left-right outer side of the seat 2 in a plan view. Therefore, the rear end portion of the armrest 4 is formed in a substantially J shape curved toward the backrest 3. Therefore, the rear ends of the elbow receiving portion 11 and the elbow pad 12 are inwardly curved portions 11a and 12a facing the backrest 3, and the tip of the inwardly curved portion 12a in the elbow pad 12 is the side surface 3c of the backrest 3. Is continuous.

As shown in FIG. 3, a recess 13 having an upward opening is formed in the elbow receiving portion 11, and a group of lower inner ribs 14 having a posture of crossing the recess 13 is formed in the recess 13. The elbow receiving portion 11 is formed with an upward peripheral rib 15 except for the tip of the inwardly curved portion 12a, and the outer side of the peripheral rib 15 is a step portion 11b. The upper end of the lower inner rib 14 is slightly lower than the upper end of the peripheral rib 15.

On the other hand, on the lower surface of the elbow pad 12, a peripheral groove 16 that fits into the peripheral rib 15 of the elbow receiving portion 11 and an upper inner rib 17 that abuts on the lower inner rib 14 of the elbow receiving portion 11 are formed. Therefore, the elbow pad 12 is held so as not to be displaced in the horizontal direction due to the fitting of the peripheral rib 15 and the peripheral groove 16. In particular, in the present embodiment, since the elbow receiving portions 11 and the elbow pads 12 are formed with inwardly curved portions 11a and 12a, deviations not only in the left-right direction but also in the front-rear direction are prevented.

As shown in FIGS. 3 (B) and 4 (C), the recess 13 of the elbow receiving portion 11 becomes deeper toward the rear, and the lower inner rib 17 adjacent to the portion of the inwardly curved portion 11a. A cross-shaped support rib 18 is formed at a height shifted downward from the elbow pad 18, and an engaging metal fitting 19 for holding the rear end portion of the elbow pad 12 upward and immovably is fixed to the support rib 18 with a screw 20. ing. The engaging metal fitting 19 may be directly fixed to the bottom surface of the recess 13 in the elbow receiving portion 11 with a screw 20 without forming the support rib 18 on the elbow receiving portion 11.

The engaging metal fitting 19 is an example of the engaging member described in claim, and is a horizontal base piece (lower horizontal piece) 19a fixed to a support rib 18 with a screw 20 and an intermediate piece (lower horizontal piece) 19a rising from the base piece 19a. It is composed of an upright piece) 19b and an engaging piece (upper horizontal piece) 19c protruding outward in the left-right direction from the intermediate piece 19b. Since the engaging piece 19c and the base piece 19a are oriented in the same direction, the engaging metal fitting 19 of the embodiment has a substantially U-shaped shape.

On the other hand, at the tip of the inwardly curved portion 12a of the elbow pad 12, an engaging hole 21 that fits into the engaging piece 19c of the engaging metal fitting 19 is formed as an example of the pad-side engaging portion according to the claim. By fitting the engaging hole 21 into the engaging piece 19c, the rear end of the elbow pad 12 is held immovably upward (in the present embodiment, the engaging hole 21 and the engaging piece). The fitting with the 19c also has a role of holding the inwardly curved portion 12a of the elbow pad 12 so as not to be able to move back and forth.)

Then, as shown in FIG. 3, the tip end portion of the elbow pad 12 is fixed to the elbow receiving portion 11 by the screw 22. The elbow receiving portion 11 and the elbow pad 12 are formed with boss portions 23 and 24 that overlap each other, the elbow receiving portion 11 has a screw insertion hole 25, and the elbow pad 12 has a female screw hole 26. ..

(3). Summary As described above, in the present embodiment, the peripheral groove 16 of the elbow pad 12 is fitted to the peripheral rib 15 of the elbow receiving portion 11 over substantially the entire circumference, and the rear end of the elbow pad 12 is fitted. Since it is held immovably upward by the engaging metal fitting 19, the elbow pad 12 can be firmly fixed so as not to be rolled up from the elbow receiving portion 11 even if it is fixed by one screw 22.

In particular, when the inwardly curved portions 11a and 12a are provided on the elbow receiving portion 11 and the elbow pad 12 as in the present embodiment, the fitting of the peripheral groove 16 and the peripheral rib 15 makes the elbow pad 12 immovable back and forth. Since the holding stopper function is exerted, the elbow pad 12 can be held in a state where it cannot be displaced back and forth and left and right even if there is some clearance between the screw 22 and the screw insertion hole 25.

Further, since the elbow pad 12 is provided with an inwardly curved portion 12a and has a bent shape, the rigidity of the rear portion is particularly high, so that it is difficult to roll even if it is made of a soft material. In particular, in the present embodiment, since the rear end portion of the elbow pad 12 is an inwardly curved portion 12a, when the elbow pad 12 is about to be rolled up, the rear end edge of the elbow pad 12 is stretched to the side surface 3c of the backrest 3. It tends to show a tendency, and it is difficult to turn up in this aspect as well.

Then, the elbow pad 12 is attached by moving the elbow pad 12 in the horizontal direction while overlapping the elbow receiving portion 11 and fitting the engaging hole 21 into the engaging piece 19c of the engaging metal fitting 19, and then fitting the elbow pad 12 into the engaging piece 19c. Is placed on the elbow receiving portion 11 and the peripheral groove 16 is fitted to the peripheral rib 15, and then the front end portion of the elbow pad 12 is fastened to the elbow receiving portion 11 with a screw 22. Installation of 12 can be done very easily.

The mold device for manufacturing the backrest 3 having the elbow receiving portion 11 forms a main mold (so-called cavity and core) that moves the backrest 3 in the front-rear direction, and the upper surface and the recess 13 of the elbow receiving portion 11. Since it is sufficient to have a slide die for forming the sliding die for forming the portion (undercut) corresponding to the engaging piece 19c of the engaging metal fitting 19, the elbow receiving portion 11 is integrated. The backrest 3 can be easily manufactured in a state where the cost is suppressed.

Further, since the engaging metal fitting 19 is a metal plate (made of steel plate) and has high strength, the fixing strength of the elbow pad 12 is also excellent. As shown in FIG. 4A, in the present embodiment, since the intermediate piece 19b of the engaging metal fitting 19 overlaps the inner surface 13a of the rear end of the recess 13, the intermediate piece 19b is held so as not to bend even if it is thin. ing. Therefore, the elbow pad 12 is excellent in the posture holding function.

Further, as shown in FIG. 4A, the inwardly curved portion 12a of the elbow pad 12 is held immovably outward in the left-right direction by the peripheral groove 16 of the elbow pad 12 and the peripheral rib 15 of the elbow receiving portion 11. Since the tip of the inwardly curved portion 12a is in contact with the inner side surface of the recess 13, the continuity between the upper surface of the elbow pad 12 and the side surface 3c of the backrest 3 can be ensured and the aesthetic appearance can be improved. .. In this case, it is preferable to bring the tip of the inwardly curved portion 12a into contact with the inner surface of the recess 13 in a state where the elbow pad 12 is slightly elastically deformed, because the contact state can be ensured.

As is clearly shown in FIG. 4A, in the present embodiment, the inwardly curved portion 12a of the elbow pad 12 faces the side surface 3c of the backrest 3 while increasing the height, and therefore, the inwardly curved portion 12a is directed toward the side surface 3c of the backrest 3. The upper surface of 12a and the side surface 3c of the backrest 3 are continuous in a curved state and inclined upward. Therefore, as compared with the case where the upper surface of the inwardly curved portion 12a and the side surface 3c of the backrest 3 are orthogonal to each other, the unity between the elbow pad 12 and the backrest 3 is enhanced and the aesthetic appearance is improved.

In the present embodiment, the inwardly curved portions 11a and 12a are formed on the armrest 4, and the elbow pad 12 and the elbow receiving portion 11 are integrated by fitting the peripheral groove 16 and the peripheral rib 16. With this configuration, when the elbow pad 12 is fitted to the elbow receiving portion 11, the inwardly curved portion 12a of the elbow pad 12 can be stretched toward the side surface 3c of the backrest 3, so that the elbow pad 12 can be stretched. There is an advantage that the aesthetic appearance can be improved by surely holding the state where the rear end surface is in contact with the backrest 3.

The form of the engaging metal fitting 19 can be variously embodied. For example, as shown in FIG. 5A, the engaging piece 19c and the base piece 19a can be formed in a crank shape facing in the opposite direction. Alternatively, as shown in FIG. 5B, an engaging hole 27 is formed in the intermediate piece 19b, and an engaging protrusion (not shown) to be fitted into the engaging hole 27 is formed at the rear end of the elbow pad 12. You may.

In the present embodiment, the rear end portions of the elbow receiving portion 11 and the elbow pad 12 generally refer to the range in which the inwardly curved portions 11a and 12a are formed, but the arrangement position of the engaging metal fitting 19 is the end close to the backrest 3. It is not limited to the edge, and can be placed somewhere where the elbow pad 12 is bent. Of course, the engaging metal fitting 19 can be arranged at a position other than the rear end portion, or can be arranged at a plurality of locations between the rear end portion and another portion. Alternatively, it may be arranged at a plurality of locations at the rear end.

Further, in the present embodiment, the engaging metal fitting 19 is in contact with the rear end inner surface 13a of the recess 13, but a space is provided between the engaging metal fitting 19 and the rear end inner surface 13a of the recess 13, and this space is provided. It is also possible to fit a downward wall provided at the rear end of the elbow pad 12. That is, it is also possible to sandwich the downward edge portion (downward wall or downward rib) of the elbow pad 12 by the engaging metal fitting 19 and the elbow receiving portion 11 (in this case, the downward claw is attached to the elbow pad 12). It may be provided and this claw may be engaged with the engaging metal fitting 19).

Although the embodiments of the present invention have been described above, the present invention can be embodied in various ways. For example, the elbow pad can adopt various forms such as a simple rectangle or an oval shape that is elongated in the front-rear direction. As for the backrest, various forms such as a form in which a pad material is arranged on the front surface and a form in which a mesh material is stretched by opening the front and back can be adopted. It is also possible to arrange an engaging member such as an engaging metal fitting at the front portion of the elbow receiving portion and screw the rear portion of the elbow pad.

Further, as a means for fixing the elbow pad, instead of using a screw, a downward engaging claw is formed on the elbow pad, while the engaging claw on the elbow receiving portion is deformed against its elasticity. It is also possible to form an engaging groove to be fitted. When a peripheral rib and a peripheral groove are provided as a means for preventing the elbow pad from slipping, it is also possible to form the peripheral rib on the elbow pad and form the peripheral groove on the elbow receiving portion.

The invention of the present application can be embodied in a chair. Therefore, it can be used industrially.
