Description

[Detailed description of the invention] [Field of industrial application] The invention consists of a pair of left and right flat drawers mounted along the lower surface of the desk top plate, and a sleeve cabinet provided below the flat drawers so as to be movable from side to side. It's about desks.

[Background of the idea]

For desks for office or study use, a flat drawer is installed on the underside of the desk top, and sleeve drawers are installed in multiple stages on the lower right side or lower left side of the desk top. As is well known, conventional single-sleeved desks have shortcomings in terms of usability and layout because the sleeves are fixed to the desk body. .

In other words, if a right-handed person uses a desk top, it is easier to use a right-sleeved desk with a wide open space on the right side, whereas if a left-handed person writes with his/her left hand, a desk top with a right sleeve is easier to use. It is said that desks with left sleeves, which have a wide open space on the left side, are easier to use, and the usability of desks differs depending on the dominant arm, but in conventional desks, the sleeves are fixed to one side (especially the right side). Therefore, the usability of the desk differed depending on one's dominant arm.

[Conventional technology]

Therefore, Japanese Utility Model Application Publication No. 48-82102 as a prior art focuses on the fact that desks generally have a footrest horizontally installed between the left and right legs, and uses this footrest to move the left and right sleeve cabinets. It is proposed that it be made movable.

That is, the invention in this publication is a support in which the rear end of the lower surface of the sleeve cabinet is locked to the footrest rod, and the front end of the upper surface of the sleeve cabinet is fixed between the left and right legs under a flat drawer provided on the desk. By being locked to the rod, the sleeve cabinet was configured to be movable left and right.

[Problem that the invention attempts to solve]

However, when the sleeve cabinet is configured to be movable from side to side using footrests, the load of the sleeve cabinet is supported by the footrests, which reduces the strength of the footrests. When a person sitting on a bicycle puts their feet on the footrest, an excessive load is applied to the footrest, which causes the footrest to easily bend and deform, causing the sleeve cabinet to wobble.

In addition, in such a structure, the vertical height of the sleeve cabinet is regulated by the vertical height dimensions of the footrest rod and the support rod below the flat drawer, so the capacity of the sleeve cabinet can be changed freely. There were also problems that made it impossible to change the design.
Furthermore, in study desks, etc., the height of the desk top plate is freely adjustable to improve the usability of the desk, but in the invention in the above publication, the height position of the sleeve cabinet is adjusted by the footrest. There was also a problem in that it could not be applied to desks with height-adjustable desk tops because of the stipulations.

The first object of the present invention is to solve the above-mentioned problems of the prior art when configuring the sleeve cabinet to be movable left and right, and the second object of the present invention is to: To provide a locking mechanism between a flat drawer and a drawer in an inexpensive and easy-to-operate form when a sleeve cabinet is provided to be movable from side to side.

In other words, when multiple sleeve drawers are installed on the sleeve of a desk, it goes without saying that it is necessary to be able to lock the sleeve drawers.
Publication No. 40-32700 discloses a desk with a fixed sleeve,
It is proposed to simplify the structure of the locking mechanism by making it possible to lock all sleeve drawers with one lock, but in this proposal,
Because all the sleeve drawers are locked at the same time,
Each time the sleeve drawer is pulled out, it must be unlocked one by one, making the unlocking and locking operations cumbersome.However, if it is left unlocked all the time, there is no point in providing a lock.

To this end, only some of the multi-stage sleeve drawers are equipped with a locking mechanism, and highly confidential documents and items are stored in the drawer with a locking mechanism, while other items are placed in a drawer with a locking mechanism for convenient removal and storage. It is convenient to prioritize and store items in a drawer that does not have a locking mechanism.

At the same time, it would be more convenient if one of the left and right flat drawers installed along the bottom surface of the desk top had a locking mechanism and the other could be freely drawn out, but if the sleeve cabinet was provided so that it could be moved left and right,
A lock for locking the sleeve drawer in the sleeve cabinet and a lock for locking the flat drawer must be provided separately, which raises the problem of increased costs and troublesome unlocking operations.

Therefore, even if the sleeve cabinet is provided so that it can be moved left and right, the present invention has a single lock that can selectively lock the upper and lower multi-stage sleeve drawers and selectively lock the left and right flat drawers. The second purpose of the present invention is to reduce the cost and improve the operability of the locking device by making it possible to perform both operations at the same time.

[Means for solving problems]

In order to achieve these objects, the present invention provides a desk in which a desk top is supported by a pair of left and right legs, and a pair of left and right flat drawers are provided along the lower surface of the desk top so that they can move back and forth. , between the left and right legs,
Cross beams are connected at appropriate intervals in the front and rear at a position below the flat drawer, and a sleeve cabinet comprising a plurality of sleeve drawers mounted on each of these cross beams can be freely positioned at a position below the right or left flat drawer. Further, the upper frame of the sleeve cabinet is suspended so as to be movable from side to side so as to be close to the lower surface of each flat drawer, and the front plate of the uppermost sleeve drawer of the sleeve cabinet is provided with:
While installing an engaging rod that moves up and down in conjunction with the unlocking operation of the lock attached to the front plate of the uppermost sleeve drawer,
An engagement hole is formed in the lower surface of the upper stile in the sleeve cabinet, into which an engagement rod that moves upward when the lock is locked is engaged, and an engagement hole is formed in the lower surface of the upper stile in the uppermost sleeve drawer. A bar rod whose upper part is movable up and down from the upper surface of the sleeve cabinet is provided above the mating hole so as to be movable up and down. The upper part is pushed up so as to protrude from the upper surface of the sleeve cabinet, and the bolt is associated with the lowering movement of the engaging rod so as to descend.
Furthermore, a locking body is provided on the lower surface of each of the left and right flat drawers to project downward and engage with the bar rod that projects upward when the sleeve cabinet is positioned below.
