Description

  The present invention relates to a table.

  In general, a desk (which may be called a table) has a top plate and its supporting members (legs, sleeve cabinets, etc.) as essential components. It is installed as an option.

Conventionally, the back panel is attached to the back of the left and right legs with screws, or the engaging claws formed on the left and right ends of the back panel are dropped into the engaging holes formed on the back of the left and right legs. There were many things that stopped (see, for example, Patent Documents 1 and 2).
Japanese Patent No. 2734787 JP-A-10-155553

  However, in the conventional back panel mounting structure, the larger the size, the more troublesome is the alignment of the screw holes formed in the left and right legs and the back panel and the alignment of the engagement holes and the engagement claws. In particular, there is a problem in that it takes time and effort when connecting work by one person. Moreover, in the latter attachment structure (connection structure by the engagement hole and the engagement claw), for example, when a desk user mistakenly kicks up the back panel, an external force is applied to the back panel from below. As a result of the engagement claws being easily removed from the engagement holes, there was also a problem that the back panel was easily removed. Further, when the back panel is not used, the holes formed on the back surfaces of the left and right legs are exposed, which causes a problem that the aesthetics are impaired.

  Incidentally, as described above, some desks include a desk panel that rises above the top surface of the top plate. Such a desktop panel is generally arranged behind the top plate. Insert insertion feet that protrude downward from the left and right rear ends of the top plate or support holes formed in the back frame. In many cases, an L-shaped bracket that overlaps the side end surface of the desktop panel and the side end surface of the top plate is fixed with screws.

  The present invention focuses on a desk top panel in order to solve the above-mentioned problems, and makes it possible to easily and firmly attach the back panel to the rear part of the desk main body by effectively using the desk top panel. It is what.

  In order to solve this technical problem, the desk according to the invention of claim 1 has the rear portion of the support body arranged below the top plate projecting rearward from the top plate, and on the projecting portion, A desktop panel that rises above the top surface of the top plate is attached, and a back panel that overlaps a rear portion of the support body is disposed below the desktop panel, and the back panel includes the desktop panel and A forward projecting portion that fits between the projecting portion of the support body is provided.

  According to a second aspect of the present invention, in the desk according to the first aspect, the support body overlaps the left and right support members that support the top plate from below and the rear portions of the left and right support members and is behind the top plate. A projecting back member as the projecting portion, and the desktop panel includes a base plate extending horizontally at a lower end thereof and resting on an upper end surface of the rear member, and facing downward to the base plate On the other hand, the forward protruding portion of the back panel is fitted on the concave groove of the baseboard from below while being mounted on the upper end surface of the back member, and cannot be pulled out backward. It is something that has become.

  According to a third aspect of the present invention, in the desk according to the second aspect, the lower end portion of the back member and the lower end portion of the back panel have a U-shaped receiving frame with an upward cross-section that fits both the lower end portions from below. It is said that it is connected by.

  According to the first aspect of the present invention, a desk top panel that rises above the top surface of the top panel is mounted on a rear part (a projecting part) that projects rearward from the top panel in the support body, and the support panel is disposed below the desk top panel. A back panel that overlaps the overhanging portion of the main body is disposed, and the back panel includes a forward projecting portion that fits between the desk top panel and the overhanging portion of the support body. The back panel can be attached to the desk main body without using screws or bolts by fitting the forward projecting portion between the front and rear portions. For this reason, attachment work can be performed easily and removal work is also easy.

  In addition, since it is not necessary to provide a hole for attaching a back panel on the rear surface of the support body, even when the back panel is not used, even if the rear surface of the support body becomes accessible to the human eye, the appearance is good and aesthetic. Will improve.

  According to a second aspect of the present invention, the forward projecting portion of the back panel is in a state of a downward opening formed on a baseboard constituting the desk top panel in a state of being placed on an upper end surface of a back member as the overhanging portion. Since it is impossible to pull back backward by fitting into the groove from below, in order to attach the back panel to the rear side of the back member, the back panel is slightly inclined so that its lower part is separated from the back member. In the inclined state, the forward projecting portion of the back panel is fitted into the concave groove of the baseboard from below, and then the back panel is pivoted forward around the forward projecting portion, thereby the forward projecting portion. The lower surface of the rear surface member may be placed on the upper end surface of the rear member and hooked. By such one-touch operation, the back panel can be easily attached to the rear surface side of the back member, so that workability is improved.

  In addition, by fitting the forward projecting portion of the back panel into the concave groove of the baseboard from below, the back panel is held so that it cannot be pulled out rearwardly. The back panel can be attached so that it cannot be pulled out backward.

  According to invention of Claim 3, since the lower end part of the said back member and the lower end part of the said back panel are connected with these both lower end parts from the lower part by the cross-sectional upward opening U-shaped receiving frame, For example, even if a desk user accidentally kicks up the back member and an external force is applied to the back panel from below, the lower end of the back panel is held inseparable from the back member. Thus, the risk that the protruding portion of the back panel will inadvertently fall out of the concave groove is significantly reduced. Thereby, the said back panel can be stably hold | maintained, without impairing the ease of attachment / detachment work.

In the state where the baseboard 45 is placed on the upper end surface of the upper frame 14, the tip of the long bolt 64 is screwed into the inner vertical groove 30 of the side frame 13 through the square hole 19 of the upper cap body 17.

(4). Details of Back Panel and Connection Structure Next, details of the back panel and a connection structure of the back member, the desktop panel, and the back panel will be described with reference to FIGS. 2, 4, and 8.

  The back panel 11 can function as a partition in combination with the desktop panel 10 positioned above, and has a sandwich structure in which metal panel plates 72 are attached to both front and back (front and back) surfaces of a core material 71 such as a honeycomb material. The left and right width dimensions are set so as to be hidden up to the rear plate of the side frame 13.

  The vertical length of the back panel plate 72 is longer than that of the front panel plate 72, and laterally long rectangular bent portions 73 projecting to the front panel plate 72 side (front side) are provided at both upper and lower ends of the back panel plate 72. Is formed. The upper bent portion 73 of the back panel plate 72 is for fitting (inserting) between the desktop panel 10 and the back member 3, and in this embodiment, the rear concave groove 56 of the baseboard 45 is tightly fitted from below. The size is set to fit. The tip (lower end) of the upper bent portion 73 is an abutting portion 73 a that is placed on the upper end edge of the upper frame 14.

  In the present embodiment, the upper bent portion 73 is fitted into the rear concave groove 56 from below, and the upper bent portion 73 is connected to the baseboard 45 and the upper frame in a state where the contact portion 73a is placed on the upper end edge of the upper frame 14. 14, the back panel 11 is suspended from the back member 3. In other words, the back panel 11 is suspended from the back member 3 by sandwiching and fixing the upper bent portion 73 between the baseboard 45 and the upper frame 14 from above and below. The upper bent portion 73 of the back panel 11 corresponds to a forward projecting portion described in the claims.

  The upper bent portion 73 may be provided partially (at an appropriate interval along the horizontal direction) on the upper end portion of the back panel plate 72. At least one (two in total) at the upper left and right ends of the back panel 72 is sufficient.

  In order to attach the back panel 11 to the rear surface side of the back member 3, the upper folded portion 73 is made to be a rear concave portion of the baseboard 45 while the back panel 11 is inclined slightly obliquely so that the lower portion of the back panel 11 is separated from the curtain plate 16. The back panel 11 is inserted into the groove 56 from below, and then the back panel 11 is rotated forward around the upper bent portion 73, and the contact portion 73 a of the upper bent portion 73 is placed on the upper edge of the upper frame 147 and hooked. 72 may be superimposed on the curtain plate body 16 of the back member 3 from behind. By such one-touch operation, the back panel 11 can be easily attached to the rear portion of the back member 3. When removing the back panel 11, the procedure is reversed.

  Further, since the upper bent portion 73 is fitted into the concave groove 56 from below, and the contact portion 73a is hooked on the upper edge of the upper frame 14 in this state, the lower portion of the back panel 11 is the curtain plate body. As long as it is not inclined obliquely away from 16, it will be stably suspended and will not fall. Therefore, it is possible to attach the back panel 11 so that it cannot be removed backward without impairing the ease of the attaching / detaching operation.

  Furthermore, in this embodiment, even when the unit desk 1 is used without attaching the back panel 11, there is no hole for attaching the back panel 11 on the rear plate of the side frame 13 that can be touched by human eyes. Good and improved aesthetics.

  The back panel 11 of this embodiment and the curtain plate 16 of the back member 3 are connected to each other by using a horizontally long and upwardly-opening U-shaped receiving frame 74. The receiving frame 74 is formed into a hollow shape having the same cross section over the entire length by extrusion molding of synthetic resin or light metal, and is detachable from the lower folded portion 73 of the back panel 11 and the lower folded portion 20 of the curtain plate body 16 from below. It is covered with. A horizontal lip 74a is formed at the upper end of the side plate portion located on the curtain plate body 16 side to hold the lower folded portion 20 so that it cannot be pulled upward.

  The left and right ends of the receiving frame 74 are formed with protruding pieces 74b that overlap the lower cap body 18 attached to the lower end of the side frame 13, and the head screws 75 penetrating the left and right protruding pieces 74b are attached to the lower cap. The receiving frame 74 is detachably fixed to the left and right side frames 13 by screwing into the inner vertical grooves 30 of the side frames 13 from below through the body 18.

  For this reason, for example, even if the user of the unit desk 1 mistakenly kicks up the curtain plate body 16 and an external force is applied to the back panel 11 from below, the lower end portion of the back panel 11 (the lower bent portion 73). ) Is held inseparable from the curtain plate body 16, and the possibility that the upper bent portion 73 will inadvertently fall out of the concave groove 56 is significantly reduced. Thereby, the back panel 11 can be stably held without impairing the ease of attachment / removal work (the back panel 11 will not be inadvertently detached).

  In addition, the receiving frame 74 of the present embodiment is fitted to the lower end portion of the back panel 11 and the lower end portion of the curtain plate body 16 from below, and then the left and right end portions thereof are screwed to the side frame 13. Therefore, when screwing, the receiving hole 74, the back panel 11, and the curtain plate body 16 can be relatively slid in the left-right direction (the longitudinal direction of the receiving frame 74) to align the screw holes. Further, the receiving frame 74 is basically a fitting type, and screwing is only required at two places on the left and right. For this reason, the attachment work of the receiving frame 74 can also be performed smoothly. Of course, the removal work of the receiving frame 74 is also easy.
