Description

  The present invention relates to a chair that can be suitably used in a free address type office.

  A free address office (for example, see the following non-patent document) that employs a free address format office layout is said to have started in the late 1980s. In the free address office, a cafe-style floor will be constructed with desks and chairs that can be used freely by anyone, without fixing the seats of individual employees.

  In the case of such a free address office, the office worker takes out necessary documents, personal computers, etc. from a locker assigned to the worker in advance, brings them into the office, sits in a vacant seat and works. To do.

  In other words, assuming such an aspect, if the office worker takes out necessary documents or personal computers from a locker, etc., and places importance on ensuring that these are positioned in the vicinity of the office worker, of course, the office worker, that is, a seated person wears it. It is also important to place the outer garment, etc., in the vicinity of the occupant himself. As a result, it is conceivable to employ a chair with a hanger in the manner as in Patent Document 1. The thing of the said patent document 1 can hang a jacket etc., without moving to another place, when a seated person sits down. And, like the chair described in Patent Document 1, the conventional chair with a hanger is a relative hanger in the chair so that the lower end of the clothes does not touch the floor as much as possible when the clothes such as outerwear are hung on the hanger.

  However, if the hanger is provided on the rear upper part of the back as in the chair described in Patent Document 1, the area occupied by the chair itself is increased as a result, and the chair is moved and managed in the office. In this case, the necessary area also increases accordingly.

  That is, when a hanger is provided on a chair in the above-mentioned free address office, it is required to position a jacket or the like while suppressing an increase in occupied area as much as possible.

  The present invention focuses on such points, and an object of the present invention is to provide a chair capable of positioning clothing such as a jacket in the vicinity of a seated person while suppressing the occupied area of the entire chair.

  In order to achieve such an object, the present invention takes the following measures. That is, the chair according to the present invention is a chair provided with a hanger on the backrest, and includes a back frame in which the backrest is paired on the left and right sides, and a horizontal beam connecting the back frames. The suspension is provided on the lower side of the horizontal beam in a suspended posture in which lateral movement is prohibited.

  Here, the “suspending posture in which movement to the side is prohibited” is not limited to a mode in which the suspension is fixed to the horizontal beam, but a symmetrical movement that protrudes vertically from the horizontal beam. Furthermore, it is a concept including an aspect in which it is swingably suspended so as to rotate in the front-rear direction.

  In such a case, since the hanger is positioned below the cross beam, it is possible to effectively avoid the problem that the hanger protrudes greatly on the back side of the chair and the area occupied by the chair itself increases. . By doing so, it is possible to effectively suppress the hanger and the clothes hung on the hanger from interfering with structures around the office. As a result, even in the free address office where the seat is not specified, the seated person can concentrate on the work without any interference or interference.

  As a configuration in which the hanger can be provided on the cross beam as compactly as possible, the hanger has a hanger body for hanging clothes, and a suspension member that suspends and supports the hanger body on the cross beam while maintaining a gap between the hanger and the cross beam. The structure which provides can be mentioned.

  In addition, if the cross beam is curved so that its central portion protrudes backward, and the hanger body has a curved shape that substantially conforms to the shape of the horizontal beam, hang the clothing forward. In addition to being easy, it is possible to effectively prevent the hanger from interfering with the surroundings due to the movement of the chair by the movement of the seated person. On the other hand, if the hanger body has a chamfered portion for guiding the clothing on the front side of both ends, it can contribute to the smooth operation of hanging the clothing forward, Preferably, it will be easy to hang backward.

  As a specific configuration for securing a space under the hanger so that long clothes can be hung without touching the floor, the backrest is a pair of back frames that form a pair of left and right frames, and between these two back frames. And a lower horizontal beam erected between the upper part of the back frame, and a lower horizontal beam erected between the lower part of the back frame. A hanger is provided on the upper horizontal beam. Things can be mentioned.

  If the upper horizontal beam and the lower horizontal beam are configured so that a space can be formed between the upper and lower beams, the upper space of the garment is positioned in the space between the upper and lower beams and the lower beam. The space between the cross beam and the upholstery can accommodate the lower side of the garment and effectively suppress an increase in occupied area when the chair and the garment are combined when hung on the hanger.

  In particular, if the space between the lower cross beam and the upholstery is larger than the space between the upper cross beam and the upholstery, the lower end of these garments will be used even when a coat or thick jacket is worn. Increasing the occupied area at the time can be preferably avoided. Furthermore, if the space between the lower cross beam and the tension fabric is positioned in front of the space between the upper cross beam and the tension fabric, the clothing can be brought closer to the seated person to further reduce the occupied area. It will be a thing.

  In order to make the hanger highly durable, it is desirable that the hanger be formed integrally with the cross beam.

  On the other hand, in the present invention, if the hanger is provided so as to be operable with respect to the cross beam, clothes can be suitably hung in a more desirable posture at the time of use.

  Furthermore, when it is desired to select whether to use the hanger according to the frequency of use of the hanger, the hanger may be provided so as to be detachable from the cross beam.

  As a specific configuration of the hanger configured to be operable, the hanger is provided so as to be slidable in the vertical direction with respect to the cross beam, and at least the suspension member is housed in the cross beam, and below the housing posture. And a use posture in which a gap is formed between the hanger body and the cross beam. If it is such, when it does not use a hanger, it can comprise compactly and the increase of the occupation area of a chair can be avoided further.

  Further, as another configuration in which the hanger is configured to be operable, the hanger is provided so as to be rotatable with respect to the cross beam, and the hanger is positioned at least at the same position as or higher than the cross beam. A non-use posture and a use posture in which a hanger body is rotated downward from the non-use posture to form a gap below the cross beam can be exemplified.

  In such a case, in the non-use posture, if the suspension member is positioned on the front side of the cross beam, an increase in the occupied area is avoided. On the contrary, in the non-use posture, the suspension member is on the rear side of the cross beam. If it positions, it can be set as the aspect which is easy to hang | wear clothes.

  According to the present invention, since the hanger is positioned below the cross beam, the problem that the occupied area of the chair itself increases can be effectively avoided. By doing so, it is possible to effectively suppress the hanger and the clothes hung on the hanger from interfering with the surrounding structures in the office, and provide a chair that allows the seated person to concentrate on work appropriately. It becomes possible to do.

It can be suppressed.

  In particular, if the space between the lower cross beam 33 and the upholstery M is formed larger than the space between the upper cross beam 29 and the upholstery M, these garments can be worn even when a coat or a thick jacket is applied. It can be suitably avoided that the lower end of 104 increases the occupied area during use. Further, if the space between the lower horizontal beam 33 and the tension fabric M is positioned in front of the space between the upper horizontal beam 29 and the tension fabric M, the clothing 104 can be brought closer to the seated person and further occupied. The area is reduced.

  In the present embodiment, necessary and sufficient strength and durability are ensured by integrally forming the hanger 103 on the horizontal beam 29.

<Modification>
And below, the modification of the hanger 103 which concerns on this embodiment is demonstrated with reference to FIG. 15 thru | or FIG. In each of these modified examples, the same components as those in the above embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  First, in the mode shown in FIG. 15A and FIG. 15B, the hanger 103 is provided so as to be operable with respect to the upper cross beam 29. Specifically, the hanger 103 is provided so as to be slidable in the vertical direction with respect to the upper horizontal beam 29, and the hanger 103 is in an accommodation posture in which at least the suspension member 109 is accommodated in the upper horizontal beam 29. The posture (Q) and the use posture (P) in which the gap 107 is formed between the hanger body 105 and the upper horizontal beam 29 by sliding downward from the non-use posture (Q) can be taken. Specifically, the upper horizontal beam 29 in the above embodiment has a suspension member accommodation portion 29e that can accommodate substantially the entire suspension member 109 and a hanger body accommodation portion 29d that can accommodate approximately the upper half of the hanger body 105. A stopper (not shown) for positioning the suspension member 109 in the use posture (P) is provided, and when the garment 104 is hung, the hanger body 105 is lowered downward as shown in FIG. (P) and when the garment 104 is not hung, the hanger body 105 is pushed upward as shown in FIG. A half of the hanger body 105 is housed in the hanger body housing portion 29d so that the non-use posture (Q) can be configured in which the upper horizontal beam 29 and the hanger 103 are formed to be substantially flush with each other. A.

  If it is such, it can be set as the chair which can handle a space more effectively by suppressing the occupation area of the chair in the state which does not use the hanger 103 effectively.

  Further, as another modified example shown in FIG. 16, the hanger 103 is provided so as to be operable with respect to the upper horizontal beam 29 as in FIG. 15. In FIG. It is assumed.

  Specifically, the hanger 103 support shaft 29f is formed by gently constricting the center in the width direction of the upper horizontal beam 29 to a columnar shape, and the hanger 103 is added to the hanger body 105 and the suspension member 109, Assuming that a C-shaped hanger pivot part 108 is further provided, the hanger 103 is prohibited from moving in the width direction by being fitted into the hanger 103 support shaft 29f by elastic deformation of the hanger pivot part 108. It can be operated to rotate in the direction. The hanger 103 includes a non-use posture (Q) in which at least the suspension member 109 is positioned at the same position as or higher than the upper cross beam 29, and the hanger body 105 is rotated downward from the non-use posture (Q). It is assumed that a use posture (P) in which the gap 107 is formed below the position can be taken.

  If this is the case, the hanger body 105 is positioned directly below the upper horizontal beam 29 by the weight of the clothing 104 (not shown) in the use posture (P) indicated by the solid line in FIG. Furthermore, if the hanger body 105 is positioned in front of the upper horizontal beam 29 as the non-use posture (Q), the occupied area of the chair can be effectively reduced. On the other hand, if the hanger body 105 is positioned behind the upper horizontal beam 29 as the non-use posture (Q), it is possible to realize an easy-to-handle aspect that constitutes a state in which the garment 104 can be easily hung. Further, the shape of the upper horizontal beam 29 as shown in FIG. 10A, that is, a shape that gently deforms into a columnar shape toward the central portion, whether the hanger 103 is attached or removed, The center portion of the upper horizontal beam 29 can be shown without a sense of incongruity.

  Although not shown in the modified example, a moderation mechanism for positioning the hanger 103 at a required angle is provided between the hanger pivoting portion 108 and the hanger 103 support shaft 29f, or the hanger body 105 is previously attached to the upper cross beam 29. An elastic urging means may be provided separately so as to be elastically urged forward or backward, and when the garment 104 is not worn, the elastic urging means can take a non-use posture (Q).

  Further, as shown in FIG. 17 (a) as another modified example, it is detachably provided by means of, for example, screws or bolts, in addition to those operatively provided as in FIG. 15 and FIG. It may be a thing. Specifically, as shown in the figure, a hanger mounting recess 29g for mounting the hanger 103 is provided by partially cutting the upper horizontal beam 29, and the hanger 103 is screwed above the suspension member 109. A hanger mounting plate portion 108a may be provided. In such a case, the hanger 103 is screwed as shown when using the hanger 103, but when the hanger 103 is not used, the dent in the center of the upper horizontal beam 29 exposed when the hanger 103 is removed is used. The hanger mounting recess 29g may be provided with a cover 29h, which is another part shown in FIG. 5B, and the surface of the horizontal beam 29 may be formed to be flush with each other.

  If it is such, when the user does not use the hanger 103 in advance, the user can set the non-use posture (Q) to which another part 29h is attached, and can effectively save the occupied area of the chair.

  Although the embodiment of the present invention has been described above, the specific configuration of each unit is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the above embodiment, the detachable and operable hanger mode is disclosed as a modified example, but of course, a mode in which a hanger that is separate from the horizontal beam is fixed by screwing or the like is adopted. May be. Moreover, the specific aspects of the hanger itself and the suspension member are not limited to those of the above embodiment, and various aspects including the existing ones can be applied.
