Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a desk suitably used in offices and other places.

[Prior Art] As is well known, desks used for office work in offices and other places have a relatively large depth dimension. Therefore, the leg space in which a person sitting on the veranda can move their legs freely is sufficient to be about half of the space on the front side of the entire space formed under the top board, excluding the area near the floor. It is.

Therefore, in offices with a large amount of files, for example, an auxiliary space a as shown in Fig. 9 may be placed at the back of the space d formed below the top C of the desk and used for file storage, etc. I try to do that. This auxiliary phase a is box-shaped with a relatively small depth dimension, and has legs f with casters e, so that it can be freely pulled out from the back of the space d to the front side. .

[Problem to be solved by the invention] By the way, in modern offices where the situation changes rapidly, desks are frequently rearranged, but if the desk is separate from the desk of assistant A, it is difficult to move it. The problem is that it takes a lot of time. Moreover, since such an auxiliary phase a is placed on the floor g via the legs f, it tends to get in the way when cleaning the floor surface. Furthermore, there are often power lines, communication lines, etc. running on the floor under the top plate, and auxiliary phase a
When pulling out or storing the caster e, there is a problem that the wiring and the caster e interfere with each other.

Furthermore, since the auxiliary phase a moves freely in any direction, there is a problem in that it may shift due to unexpected external forces and collide with the leg of a desk or the like, causing damage.

The object of the present invention is not only to solve these problems, but also to provide a desk that makes it particularly easy to put things in and take them out of sliding shelves.

[Means for Solving the Problems] In order to achieve the above objects, the present invention takes the following measures.

That is, the desk according to the present invention has a sliding shelf suspended under the top plate via a guide rail, and the sliding shelf can be moved from a storage position set at the back to a drawer position set near the use edge. The table is configured so that it can be slid between the desks, and the lower surface of the top plate is provided with a guide rail that extends from the edge in use to the back. It is suspended so that it can slide forward and backward, with the lower surface floating above the floor, and the guide rail consists of a front wheel guide support section that guides the front wheels, and a rear wheel guide support section that guides the rear wheels. The wheel support surface of the front wheel guide support section is formed approximately parallel to the top plate, and the wheel support surface of the rear wheel guide support section is formed on the slide shelf in the drawn-out position. The drawer holding surface part that receives the rear wheels is
It is characterized in that it is formed to be lower than the storage receiving surface portion that receives the rear wheels of the slide shelf in the storage position.

In order to securely and stably hold the slide shelf in the drawer position without installing a special locking mechanism, the drawer holding surface should be
It is best to create a valley that is lower than the receiving surfaces in front and behind it.

In addition, in order to reliably and stably hold the slide shelf in the storage position without using a special locking mechanism, the receiving surface for storage should be sloped downward toward the unused edge, and the end It is advisable to provide a locking surface for locking the rear wheels of the sliding shelf.

The sliding shelf includes at least left and right side end members, a shelf element that is installed between the lower ends of these end members and supports stored items, and a lock that prevents stored items on these shelf elements from falling backwards. It is only necessary to include a stop element.

The side end members are not limited to plate-like ones, and may be I-shaped in side view, double-shaped in side view, U-shaped in side view, or the like.

The shelf element may be plate-shaped, but may also be net-shaped.

In order to easily move the sliding shelf to the storage position, it is preferable to provide a kick plate on the bottom front surface of the sliding shelf for pushing the sliding shelf with a foot.

``Function'' With this kind of configuration, when the sliding shelf is pulled forward and slid to the drawer position, the unused edge of the shelf becomes lower, so the used side of the sliding shelf faces diagonally upward. This makes it easy to place stored items such as files on the shelf element or to take out stored items on the shelf element. If you press the slide shelf from this position and slide it to the storage position in the back, it will return to its original height position on the unused side, and a space for the lower legs will be formed under the top plate, allowing you to store the slide shelf and its storage. Things will be stored out of the way.

However, since this sliding shelf does not have legs and is supported by floating above the floor, it does not get in the way of floor cleaning or interfere with wiring on the floor when moving. Further, since this sliding shelf is supported by the guide rail and only moves back and forth within a limited range, there is no risk of it moving loosely due to external force and colliding with the legs of the table or the like.

"Embodiment" An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

FIG. 1 shows a side cross section of the desk 1. This desk 1 has a top plate 3 supported by legs 2, a curtain plate 4 provided between the legs 2 except on the use surface 11 side, and a slide shelf 5 disposed below the top plate 3.

To be more specific, a guide rail 6 is provided on the lower surface of the top plate 3 and extends inward from the use edge 31 side. The storage position A (see the solid line in Fig. 1 and Fig. 2) with the slide shelf 5 set at the back, and the drawer position B set near the use edge 31 (as shown in Fig. 1) (see Figure 3).

As shown in FIGS. 2 and 3, the slide shelf 5 includes left and right side end members 51, a shelf element 52 that is installed between the lower ends of these both end members 51 and supports stored items, and a side end member. 5
1, and a locking element 54 provided on the unused edge side of the side end member 51 to prevent stored items on the shelf element 52 from falling backward. It is box-shaped, and files and the like can be stored in this sliding shelf 5 from the use surface 11 side.

The side end member 51 and shelf element 52 of this embodiment are each plate-shaped, and a handle 58 for pulling out the slide shelf 5 toward the front is provided on the front end surface of the upper plate 53. Note that this handle 58 may be provided protruding from the front end surface of the shelf element 52. Further, a kick plate 59 is provided on the front end surface of the shelf element 52, which is the front surface of the bottom of the slide shelf 5, for pushing the slide shelf 5 to the back with the foot.

Both ends of the slide shelf 5 are suspended and supported by the top plate 3 via a pair of guide rails 6.

As shown in FIGS. 1 and 4, the guide rail 6 includes a front wheel guide support portion 62F that suspends and supports the slide shelf 5 on one side of a hanging piece 61 hanging from the top plate 3; A rear wheel guide support portion 62R is provided respectively. The hanging piece 61 is made of sheet metal, and is attached to the lower surface of the top plate 3 using bolts 63 at the front and rear ends of the upper bent portion 61a.

The front wheel guide support part 62F is made of sheet metal and has a C-shaped cross section, and is fixed to the hanging piece 61 by spot welding or the like, and supports the front wheel 56F pivoted on the suspension arm 55F of the slide shelf 5. is housed in this front wheel guide support portion 62F. On the inside of the bottom wall of the front wheel guide support part 62F, a horizontal wheel support surface 65F that removably supports the front wheel 56F is formed substantially parallel to the top plate 3. A stopper 65 for stopping the slide shelf 5 at the drawn-out position B is provided at the front end. The rear wheel guide support part 62R is formed by bending the lower end of the hanging wall 61 into an L shape, and the rear wheel 56R pivoted on the suspension arm 55R of the slide shelf 5 is connected to the rear wheel guide support part 62R. It is housed within the support portion 62R. Thus, a wheel support surface 65R that supports the rear wheel 56R in a transferable manner is formed on the inner side of the bottom wall of the rear wheel guide support portion 62R.

This wheel support surface 65R has a drawer standby surface portion 65R1 that receives the rear wheels 56R of the slide shelf 5 in the drawer position B.
It is formed to be lower than the storage standby surface portion 65R2 that receives the rear wheel 56R of the slide shelf 5 at the storage position A, and also forms a valley that is lower than the reception surface portions before and after the storage standby surface portion 65R2. . Furthermore, the storage standby surface portion 6
5R2 lights a slope that becomes lower towards the unused edge side,
A locking surface 65R3 for locking the rear wheel 56R of the slide shelf 5 is provided at the rear end in the vertical direction. The left and right pairs of parallel guide rails 6 are arranged such that their front wheel guide support portions 62F are opposite to each other, and in this embodiment, a drawer 7 is provided on the opposing surface 6a of both guide rails 6. A drawer rail 8 is attached for slidable support. As shown in FIG. 4, the drawer rail 8 includes a hanging piece 81 hanging from the top plate 3 and a guide portion 82 having a C-shaped cross section.
It is made of sheet metal and is integrally constructed with the drawer 7.
The flange portion 72 provided on the side plate 71 of the drawer 7 is supported from the lower surface side so as to be movable back and forth, and the guide portion 82 supports the drawer 7
A rear end roller 73 which is pivoted to the rear end of the side plate 71 is rotatably guided and supported. Drawer 7 is the fifth
As shown in the figure, it comprises a chain part 74, a side plate 71, a bottom plate 75, and a back plate 76, and is arranged in the space S formed between the guide rails 6 in the manner described above. There is.

With such a configuration, when the slide shelf 5 is in the storage position A, the slide shelf 5 is stably held in a substantially horizontal position. When grasping the handle 58 from this storage state and pulling the slide shelf 5 toward you, the rear wheels 56R first climb over the top of the storage standby surface portion 65R2, and then move toward the drawer standby surface portion 65R1. I'm going to go.

This bowing receiving surface part 65R1 and storage waiting surface part 65R2
Since the space between the slide shelf 5 and the
As the rear wheel 56R is moved to the side, the position of the rear wheel 56R gradually decreases. On the other hand, since the front wheels 56F move horizontally, the use side of the slide shelf 5 gradually faces diagonally upward (this means that the front wheels 56F contact the stopper 65, and the rear wheels 56R move toward the drawer standby side). When reaching part 65R1,
As shown in FIGS. 1 and 3, this slide shelf 5 is stably held with its use side facing diagonally upward.

By sliding the slide shelf 5 from the storage position A to the drawer position B in this way, the shelf element 52
It becomes easy to place stored items (not shown) such as files thereon, or to take out stored items on the shelf element 52. When the kick plate 59 is depressed from this drawer position B and the slide shelf 5 is slid to the storage position A in the back, the slide shelf 5 returns to its original position and a lower limb space T is created under the top plate 3. is formed, and the slide shelf 5 and its stored items are stored out of the way. Also, when the kick plate 59 provided on the bottom front of the slide shelf 5 is pressed with a foot, the slide shelf 5
Since a component force acts in the direction of lifting the unused edge side of the slide shelf 5 upward using the front wheel 56F as a fulcrum, the rear wheel 5
6R climbs the wheel support surface 65R relatively easily.

However, since this slide shelf 5 is suspended and supported by the top plate 3 of the desk 1, when the desk 1 is moved, it is necessary to
Therefore, there is no need to separately transport only the shelf 5. Further, since the sliding shelf 5 does not have legs and is supported apart from the floor F, it will not interfere with floor cleaning or interfere with wiring on the floor when moving. Furthermore, since this sliding shelf 5 is supported by the guide rail 6 and only moves back and forth within a limited range,
There is no risk of it moving loose due to external force and colliding with the legs 2 of the desk 1, etc. Moreover, this sliding shelf 5 is held in a substantially horizontal position at the storage position A, and its use surface is diagonally upward at the drawer position B, so that it is possible to easily take in and take out stored items from diagonally above in a comfortable position. I can do it.

In addition, the sliding shelf includes at least the left and right side end members,
It is only necessary to provide a shelf element that is installed between the lower ends of these side end members and supports the stored items, and a locking element that prevents the stored items on the shelf element from falling backward. For example, the sixth It may be as shown in FIGS. That is,
The sliding shelf 105 shown in FIG. 6 is constructed by constructing a plate-shaped shelf element 152 between the lower ends of a side end member 151 that has a single-shape in side view, and fixing a plate-shaped locking element 154 to the rear end of these elements. The upper ends of the both side end members 151 are suspended and supported by guide rails via suspension arms, rollers, etc. (not shown). The sliding shelf 205 in FIG.
2, and a locking element 254 is provided at the rear end thereof, and the upper ends of the both side end members 251 are suspended and supported by a guide rail via suspension arms, rollers, etc. (not shown). It is. The sliding shelf 305 in FIG. 8 is constructed by constructing a plate-shaped shelf element 352 between the lower ends of a side member 351 having a two-letter shape in side view, and fixing a locking element 354 to the rear end of the plate-like shelf element 352. The upper ends of both side end members 351 are suspended and supported by guide rails via suspension arms, rollers, etc. (not shown). In addition, the shelf element is
It may be plate-shaped as explained above, but it may also be net-shaped.

Furthermore, it goes without saying that the configuration of the guide rail is not limited to that of the embodiment described above.

[Effects of the Invention] Since the present invention has the above-described configuration, it is possible to eliminate the complexity of moving desks and to smoothly rearrange or relocate the desks, and also to facilitate cleaning of the space under the top board. Furthermore, since there is no interference between the sliding shelf and the wiring on the floor, it is possible to provide a desk whose sliding shelf is extremely easy to use. Furthermore, when the sliding shelf of this desk is pulled out to the drawer position, its use side faces diagonally upwards, making it easy to put in and take out stored items in a comfortable position, making it particularly user-friendly. ing.

Also, if the pull-out receiving surface that receives the rear wheels of the slide shelf in the pulled-out position is made into a valley that is lower than the front and rear receiving surfaces, this will prevent the rear wheels from moving back and forth on their own. There is no. Therefore, the sliding shelf can be reliably and stably held in the drawn-out position without providing a special locking mechanism or the like.

On the other hand, the storage standby surface part that receives the rear wheels of the slide shelf in the storage position has a slope that becomes lower toward the non-use edge, and at the end thereof there is a locking surface that locks the rear wheels of the slide shelf. By providing a surface, it is possible to prevent the rear wheels from moving forward and backward. As a result, the slide shelf can be stably held in the storage position without using a special locking mechanism.

The sliding shelf is made up of left and right side end members, a shelf element that is installed between the lower ends of these end shrines to support stored items, and a lock that prevents stored items on this shelf element from falling backwards. The structure can be made relatively simple by providing the following elements.

In addition, the side end member may be plate-shaped, I-shaped in side view,
When the sliding shelf is made into a 2-shape in side view or a U-shape in side view, or when the shelf element is made into a plate-like or net-like form, it is possible to reduce the weight of the sliding shelf. , its form can be changed in various ways, and it can be made into a sliding shelf with a good appearance.

Furthermore, if a kick plate is provided on the bottom front of the slide shelf, the slide shelf can be easily moved from the drawer position to the storage position in a comfortable posture by pressing the kick plate with your foot, making it especially easy to use. It can be made into something good.
