Description

[Technical Field]

[0001] This invention relates to a table drawer rail set that can be detachably attached to the top of a table or a desk without drawers, allowing for easy installation of drawers on tables or desks without drawers. [Background technology]

[0002] As a preventative measure against COVID-19 infection in the workplace, while encouraging telecommuting and reducing commuting, an increasing number of offices are redesigning their layouts and adopting free-address systems. Unlike traditional fixed seating, free-address systems allow employees to freely choose their own seats, leaving little storage space around the desk for personal belongings, leading to the consideration of retrofitting drawers. Generally, tables consist of a tabletop and legs, with no drawers. Furthermore, desks can be divided into saddle-style and sleeveless desks. As is well known, saddle-style desks have drawers directly below the tabletop or on one or both sides of the tabletop, while sleeveless desks have no drawers below the tabletop.

[0003] Among such tables and desks, drawer sets and drawer structures that can easily install drawers, particularly for those that do not have drawers, have been proposed in Patent Documents 1 and 2, etc.

[0004] Patent document 1 relates to a desk drawer set, which comprises a drawer, a pair of guide sleeves made of magnetic metal that support the drawer on both sides, allowing it to be pulled out and slid back, and a pair of magnetic plates that are fixed to the underside of the desk top and attach the drawer by attracting the guide sleeves, with each magnetic plate being configured to have a generous width.

[0005] To set this desk drawer set on the underside of the desk top, the distance between the guide sleeves is set to accommodate the width of the drawer, which is determined by both the width of the desk top and the minimum size of the drawer for that desk. A magnetic plate with a width large enough to accommodate this distance is selected and pre-attached to the underside of the desk top. With the guide sleeves fitted to the left and right sides of the selected drawer, the drawer is gently lifted from the underside of the desk top until the top surfaces of the guide sleeves approach the undersides of the magnetic plates affixed to the underside of the desk top, causing the guide sleeves and magnetic plates to magnetically attract each other. As a result, the drawer is attached to the underside of the desk top via the guide sleeves, and the drawer set, centered on the drawer, is securely set in the desired position.

[0006] This desk drawer set is configured in this way and has the following effects. a) To make it possible to mount various drawers of different sizes on one desk by replacing them with other drawers, and the replacement work is extremely simple and reliable and can be accomplished in a very short time. b) It expands the range of work that can be done using one desk, improving work efficiency and contributing to the utilization of waste materials.

[0007] Patent Document 2 relates to a drawer support structure for a table or the like, in which locking grooves with a roughly U-shaped cross section are formed facing each other or in the same direction at the front and rear of the drawer depth direction on the underside of the table top, while lockable claws that can be detachably fitted into the locking grooves are formed at the front and rear of the upper surface of the drawer receiving member that supports the drawer body, facing the opposing locking grooves, so that the drawer body is slidably supported on the drawer receiving member.

[0008] In this drawer support structure, when a center drawer or other drawer is to be installed on a tabletop, particularly one whose underside is generally flat and does not have any drawer receiving members, for example, two locking grooves, each with a roughly U-shaped cross section, are provided on the underside of the tabletop at the front and rear, facing each other or facing the same direction, and extending the entire length of the front width of the tabletop or to any required length.The drawer body is supported and attached by releasably engaging and supporting the locking claws formed on the drawer receiving members in these grooves, so that no fixing means such as screws are used, and the drawer body including the drawer receiving members can be easily attached and detached in the desired position, making it extremely convenient to handle.

[0009] Recently, online shopping services using the Internet have provided drawers that can be easily attached to tables and the like using screw-type, clamp-type, adhesive-type, and the like. In a screw-fastened drawer, a pair of drawer receiving members, such as rails, that receive the drawer are fastened to the bottom of the top plate with screws, and the drawer is attached to this drawer receiving member. In a clamp-type drawer, a pair of clamp devices each having a drawer support portion is fixed to the front end of the top plate, and the drawer is attached via each of the drawer support portions of the clamp devices. In adhesive drawers, a drawer receiving member such as a pair of rails that receives the drawer is fixed to the bottom of the top plate with adhesive, and the drawer is attached to this drawer receiving member.

[0010] [Patent Document 1] Utility Model Registration No. 3065414 [Patent Document 2] Japanese Utility Model Application Publication No. 05-23940 Summary of the Invention [Problem to be solved by the invention]

[0011] However, the above-mentioned conventional drawer rail sets for various tables have the following problems. (1) The desk drawer set of Patent Document 1 requires a pair of magnetic plates to attach the drawers, and these magnetic plates are relatively large, making the entire drawer set bulky and making it difficult to easily attach or remove the drawer set from a table. (2) The drawer support structure of Patent Document 2 requires a locking groove with a roughly U-shaped cross section on the underside of the table top, and therefore cannot be applied to ordinary tables or desks. (3) With modern tables, screw-fastening methods cannot be used depending on the material of the table top, as screws cannot be used. Clamp-type methods involve attaching a clamp device to the front end of the table top, and the drawer is supported by each drawer support part of this clamp device. This means that the drawer is only supported on the front side of the table top, not the back, and therefore cannot be used for deep drawers. Adhesive-type methods are not strong enough to support drawers that can withstand heavy loads.

[0012] The purpose of this invention is to solve these problems of the past, and to provide a table drawer rail set of this type that has a simple overall structure and can be easily attached and removed from tables, can be applied to general tables and desks, the top plate can be made of any material, can be used for drawers with both long and short lengths in the depth and width directions, and can accommodate heavy drawer loads. [Means for solving the problem]

The gist of this is as follows.

[0014] The present invention preferably further comprises the following features: (1) Each of the four drawer rail mounting parts has a U-shaped cross section and includes an elongated, flat upper plate that can abut against the top surface of the tabletop, an elongated, flat lower plate that can abut against the bottom surface of the tabletop, and a flat middle plate that connects one end of the upper plate and the lower plate and can abut against the end surface of the tabletop. The rail part has a C-shaped cross section and includes an elongated, flat upper plate that can abut against the lower plate, a lower plate that extends parallel to the upper plate, a middle plate that is connected between one side of the upper plate and the lower plate and connects the upper plate and the lower plate, and a rail plate that rises convexly from the lower plate toward the upper plate. The upper plate of the rail part is fixed to the lower plate of the mounting part, and the mounting part and the rail part are joined together. (2) Each of the two inter-rail holding parts is cylindrical and has a cross-sectional shape that can fit between the rail parts of each set of two drawer rail mounting parts and a predetermined length. (3) The four drawer rail mounting parts and the two rail support parts are each made of metal, synthetic resin, wood, or a combination thereof. (4) Each of the four drawer rail mounting parts has an anti-slip plate interposed between the upper plate of the mounting part and the upper surface of the top plate. [Effects of the Invention]

[0015] In the drawer rail set for tables of the present invention, with the above-mentioned configuration, two sets of drawer rail mounting parts, each consisting of any two of the four drawer rail mounting parts, are attached in parallel to both ends of the tabletop and facing each other between both ends of the tabletop, and rail-to-rail retaining parts are bridged between the rail parts of each set, holding the rail parts in series toward both ends of the tabletop, and the drawer is attached between the two sets of drawer rail mounting parts on the underside of the tabletop, engaging with the rail parts of each set, so that it can slide toward both ends of the tabletop, thereby achieving the following exceptional effects unique to the present invention. (1) The overall structure is simple, making it easy to attach and detach from a table, etc. (2) It can be applied to ordinary tables and desks. (3) The top plate can be made of any material. It can be used for drawers with long or short depths and widths. (4) It can handle heavy drawer loads. [Brief explanation of the drawings]

[0016] [Figure 1] FIG. 1 is a perspective view showing a portion of the overall configuration of a table drawer rail set according to one embodiment of the present invention; [Figure 2] FIG. 10 is a side view showing the configuration of each part of the table drawer rail set; [Figure 3] 10 is an end view showing the configuration of each part of the table drawer rail set; DETAILED DESCRIPTION OF THE INVENTION

[0017] Next, an embodiment of the present invention will be described with reference to the drawings. Figure 1 shows the overall configuration of a table drawer rail set with some parts omitted, and Figures 2 and 3 show the configuration of each part of the table drawer rail set.

[0018] As shown in Figure 1, the table drawer rail set S (hereinafter referred to as this set S) is used to attach detachable drawers to tables that have a tabletop and multiple legs supporting the tabletop, as well as tables that do not have drawers. Hereinafter, this set S will be used as an example of a table commonly known as a face-to-face, free address table used in offices. Hereinafter, this free address table will simply be referred to as the table.

[0019] This set S is configured with four drawer rail mounting parts 1, two inter-rail holding parts 2, and two or one drawer 3. Note that Fig. 1 only shows a portion of a pair of drawer rail mounting parts 1, one inter-rail holding part 2, and one drawer 3.

[0020] Each of the four drawer rail mounting parts 1 has a groove-shaped shape that can fit the end of the table top, and has a mounting part 11 that can be externally fitted onto this end, and a rail part 12 that is arranged parallel to the bottom of the mounting part 11 and formed as a rail for the drawer 3.

[0021] In this case, as shown in Figures 2 and 3, the mounting part 11 is formed with a U-shaped cross section from a metal material such as aluminum, a synthetic resin material, wood, or a combination of these. Here, aluminum is used. Thus, the mounting part 11 includes an elongated, flat upper plate 111 that can abut the top surface of the tabletop, an elongated, flat lower plate 112 that can abut the bottom surface of the tabletop, and a flat intermediate plate 113 that connects one end of the upper plate 111 and the lower plate 112 and can abut the end surface of the tabletop. In this case, the upper plate 111 is a horizontally elongated, rectangular flat plate that is relatively short and can engage with the top surface of the tabletop. The lower plate 112 is a horizontally elongated, rectangular flat plate that is relatively long because the rail part 12 is joined to the lower plate 112. Intermediate plate 113 is a rectangular flat plate that extends vertically and is elongated in the width direction, and has the same width as upper plate 111 and lower plate 112. It has a predetermined height so as to ensure a dimension between upper plate 111 and lower plate 112 that is the same as or slightly larger than the thickness of the tabletop of the table that this set S is intended for, in this case the latter. Note that here, mounting part 1 is assumed to have a length of about 40 cm on lower plate 112.

[0022] In this case, as shown in Figures 2 and 3, the rail part 12 is formed into a rectangular C-shaped cross section from a metal material such as aluminum, a synthetic resin material, wood, or a combination of these. Here, aluminum is used. Thus, the rail part 12 includes an elongated, flat upper plate 121 that can abut against the lower plate 112 of the mounting part 11, a lower plate 122 that extends parallel to the upper plate 121, a middle plate 123 that is connected between one side of the upper plate 121 and the lower plate 122 and connects the upper plate 121 and the lower plate 122, and a rail plate 124 that protrudes from the lower plate 122 toward the upper plate 121. In this case, the upper plate 121 and the lower plate 122 are each a rectangular, flat plate that extends horizontally and is elongated in the length direction, and are formed relatively long as rail materials. The middle plate 123 is a rectangular flat plate that extends vertically and is elongated in the length direction. It has the same length as the upper plate 121 and the lower plate 122, and has a predetermined height so as to ensure the necessary gap between the upper plate 121 and the lower plate 122 as a rail member. The rail plate 124 is a rectangular flat plate that extends vertically and is elongated in the length direction. It has the same length as the middle plate 123 and protrudes upward along the other side of the lower plate 122 and parallel to the middle plate 123 to a height smaller than the height of the middle plate 123 that can receive and engage the rail engagement portion 31 of the drawer 3, which will be described later as the rail plate 124. An open surface is formed between the rail plate 124 and the upper plate 121 so that the rail engagement portion 31 of the drawer 3 can be inserted therethrough. Note that the rail part 12 here is assumed to be approximately 40 cm long.

[0023] In this way, the upper plate 121 of the rail part 12 is fixed to the lower plate 112 of the mounting part 11 by welding, screwing, or the like, in this case by the former, and the mounting part 11 and the rail part 12 are integrated.

[0024] In addition, in this set S, as shown in Figures 2 and 3, each of the four drawer rail mounting parts 1 has an anti-slip plate 13 interposed between the upper plate 111 of the mounting part 11 and the upper surface of the top plate.

[0025] In this case, the anti-slip plate 13 is formed in a flat plate shape from an elastic material such as rubber. In this case, the anti-slip plate 13 is formed in a rectangular shape having approximately the same length and width as the inner surface of the upper plate 111 so that it can be interposed between the upper plate 111 and the top plate of the mounting part 11, and is formed in a continuous flat plate shape with a thickness that allows it to be compressed between the upper plate 111 and the top plate of the mounting part 11. Note that the anti-slip plate 13 may be divided into multiple pieces.

[0026] Each of the two inter-rail holding parts 2 can be bridged between the rail parts 12 of each of the two sets of drawer rail mounting parts 1 by combining two sets of drawer rail mounting parts 1 arbitrarily selected from the four drawer rail mounting parts 1, and holds the rail parts 12 of each of the two sets in series in the horizontal direction.

[0027] Each of the two inter-rail holding parts 2 is formed in a cylindrical shape having a predetermined length and a cross-sectional shape that can be fitted between the rail parts 12 of the two sets of two drawer rail mounting parts 1.

[0028] In this case, the inter-rail holding part 2 is made of a metal material such as aluminum, a synthetic resin material, wood, or a combination thereof, and is formed into a rectangular tube shape with a square cross section so that it can fit into the rail part 12 of the drawer rail mounting part 1. Aluminum is used here. The inter-rail holding part 2 thus comprises an upper plate 21 extending in contact with the inner surface of the upper plate 121 of the rail part 12, a lower plate 22 extending parallel to the upper plate 21 and in contact with the inner surface of the lower plate 122 of the rail part 12, one side plate 23 connected between one side of the upper plate 21 and the lower plate 22 and extending in contact with the inner surface of the middle plate 123 of the rail part 12, and another side plate 24 extending parallel to the one side plate 23 and along the inner surface of the rail plate 124 of the rail part 12 with a predetermined gap therebetween. In this case, the top panel 21, bottom panel 22, one side panel 23, and other side panel 24 are each a rectangular flat panel elongated in the length direction, with a predetermined length that allows the inter-rail holding part 2 to span between the two rail parts 12. The top panel 21 and bottom panel 22 each have a predetermined width slightly smaller than the width between the inner surface of the middle panel 123 and the inner surface of the rail panel 124, so that the inter-rail holding part 2 can fit between the middle panel 123 and the rail panel 124 of the rail part 12 with the necessary gap for engagement between the rail engagement portion 31 of the drawer 3 (described later) and the rail panel 124. The one side panel 23 and the other side panel 24 each have a predetermined height that is the same as or slightly smaller than the height between the inner surfaces of the upper panel 121 and the lower panel 122, so that the inter-rail holding part 2 can be fitted between the upper panel 121 and the lower panel 122 of the rail part 12 without any gaps. Note that the inter-rail holding part 2 here is assumed to be approximately 80 cm long.

[0029] Either two or one drawer 3 is mounted between the two sets of drawer rail mounting parts 1 and slidably engaged along the two sets of rail parts 12. Here, two drawers 3 are provided.

[0030] Each drawer 3 is formed in a case shape with an opening at the top, and has a pair of rail engaging portions 31 on both sides so as to be engageable with each rail plate 124 of the rail part 12.

[0031] In this case, each drawer 3 is formed from a synthetic resin material into a rectangular case shape sized to be arranged in series across the width of the table, and a pair of rail engagement portions 31 are integrally formed from the upper part of each side surface with an inverted L-shaped cross section facing outward. In this way, each drawer 3 has a rectangular bottom surface 301 that is long in the width direction of the table, side surface portions 302 that rise to a predetermined height on both sides of this bottom surface 301, and both end surface portions 303 that rise to a predetermined height on both ends of this bottom surface 301. Note that one of the end surface portions 303, which is located on the end side of the table, has all or part of its entire periphery projecting outward so as to be able to come into contact with at least the end of the rail part 12, and this forms a stopper 3031. The pair of rail engaging portions 31 extend outward from the upper portions of both side surface portions 302 and include upper surface engaging portions 311 that can engage with the upper surface portion of the rail plate 124 of the rail part 12, and inner surface engaging portions 312 that can engage along the inner surface portion of the rail plate 124. Note that the drawer 3 may be made of a synthetic resin material, a metal material such as aluminum, wood, or a combination thereof.

[0032] The set S has this configuration. When the set S is used, two sets of drawer rail mounting parts 1, two of which are selected from the four drawer rail mounting parts 1, are attached in parallel to both ends of the table top and facing each other between the ends of the table top, and rail-to-rail holding parts 2 are bridged between the rail parts 12 of each set, so that the rail parts 12 are held horizontally in series toward both ends of the table top and parallel between each set. In this way, two drawers 3 are attached between the two sets of drawer rail mounting parts 1 on the underside of the table top, with the rail engagement parts 31 of each drawer 3 engaging with the rail plates 124 of each rail part 12 of each set, so that they can slide toward both ends of the table top.

[0033] Figure 1 also shows an example of how to use this set S.

[0034] First, the four drawer rail mounting parts 1 are arbitrarily divided into two sets of two drawer rail mounting parts 1. The two sets of drawer rail mounting parts 1 are then attached in parallel to both ends of the tabletop, facing each other between both ends of the tabletop. Next, two inter-rail holding parts 2 are spanned between the rail parts 12 for each set. In this case, for each set, first, one end of the inter-rail holding part 2 is inserted into one of the rail parts 12 from its open end, and then the other end of the inter-rail holding part 2 is inserted into the other rail part 12 from its open end, thereby spanning the two inter-rail holding parts 2 between the rail parts 12 for each set. In this way, the rail parts 12 of each set are held in series horizontally on the underside of the tabletop toward both ends of the tabletop, and parallel to each other between each set. Then, two drawers 3 are attached between two sets of drawer rail mounting parts 1 on the underside of the tabletop, with the rail engagement portions 31 on both sides of each drawer 3 hooked onto the rail plates 124 of each rail part 12 of each set from above, so that they can slide toward both ends of the tabletop on the rail plates 124. In this way, the two drawers 3 are attached to the front and rear ends of the underside of the table, respectively, so that each drawer 3 can be pulled out toward the front and pushed in toward the rear at each end. Note that the stoppers 3031 of each drawer 3 abut against the ends of the rail parts 12 at each end of the table, preventing each drawer 3 from being pushed too far toward the rear.

[0035] This type of attachment of Set S to a table allows for easy installation and removal without the entire Set S becoming too large. The structure of the four drawer rail mounting parts 1 of Set S allows it to be used on a general table. Furthermore, the attachment method of the four drawer rail mounting parts 1 of Set S means that, unlike recent screw-fastening methods, the table top can be made of any material. The attachment method of the drawer 3 using the four drawer rail mounting parts 1 of Set S means that, unlike recent clamp-fastening methods, the entire drawer 3 is supported, allowing it to be used with drawers that are deep, and its strength allows it to accommodate drawers that can withstand heavy loads.

[0036] As explained above, the set S includes four drawer rail mounting parts 1, two rail-to-rail holder parts 2, and two drawers 3. When using the set S to equip a table with drawers, two sets of drawer rail mounting parts 1, two of the four drawer rail mounting parts 1, are arbitrarily selected and attached to both ends of the tabletop in parallel and facing each other between the ends of the tabletop, and the rail-to-rail holder parts 2 are bridged between the rail parts 12 of each set to hold the rail parts 12 in series toward both ends of the tabletop. Then, two drawers 3 are attached between the two sets of drawer rail mounting parts 1 on the underside of the tabletop, engaging with the rail parts 12 of each set so that they can slide toward both ends of the tabletop.

[0037] In this way, the parts for equipping the table with the drawers 3, i.e., the four drawer rail mounting parts 1 and the two rail holding parts 2, have a simple shape and can be easily attached to the tabletop, so the set S has a simple structure overall and can be easily attached to and removed from the tabletop. Furthermore, the way set S is attached to the table means that the tabletop does not need to have a special shape, the tabletop can be made of any material, and it can accommodate drawers of any length in the depth and width directions, and even drawers with a large load.

[0038] The present set S further has the following advantages due to the following configurations.

[0039] Each of the four drawer rail mounting parts 1 has a mounting part 11 formed with a U-shaped cross section and including an elongated, flat upper plate 111 that can abut against the upper surface of the top plate, an elongated, flat lower plate 112 that can abut against the underside of the top plate, and a flat middle plate 113 that connects one end of the upper plate 111 and the lower plate 112 and can abut against the end surface of the top plate. The rail part 12 has a C-shaped cross section and includes an elongated, flat upper plate 121 that can abut against the lower plate 112 of the mounting part 11, a lower plate 122 that extends parallel to the upper plate 121, a middle plate 123 that is connected between one side of the upper plate 121 and the lower plate 122 and connects the upper plate 121 and the lower plate 122, and a rail plate 124 that rises convexly from the lower plate 122 toward the upper plate 121. In this way, the upper plate 121 of the rail part 12 is fixed to the lower plate 112 of the mounting part 11, and the mounting part 11 and the rail part 12 are joined together as a single unit. Each of the two inter-rail holding parts 2 is formed in a cylindrical shape having a predetermined length and a cross-sectional shape that can be fitted between the rail parts 12 of each pair of two drawer rail mounting parts 1. With the configuration of the four drawer rail mounting parts 1 and the two inter-rail holding parts 2, each of the drawer rail mounting parts 1 and each of the inter-rail holding parts 2 can be made into a simple shape and easily attached to the top plate.

[0040] The four drawer rail mounting parts 1 and the two inter-rail holding parts 2 are each made of metal, synthetic resin, wood, or a combination thereof. By selecting an appropriate material from these, various designs can be applied to the set S, thereby increasing the design variation of the set S. In addition, a wide variety of sets S can be provided, from inexpensive to high quality.

[0041] Each of the four drawer rail mounting parts 1 has an anti-slip plate 13 interposed between the upper plate 111 of the mounting part 11 and the upper surface of the top plate. The four drawer rail mounting parts 1 can be securely fixed to the tabletop using this non-slip plate 13. Furthermore, by using this non-slip plate 13, the same size drawer rail mounting parts 1 can be adapted to different tabletop thicknesses for various tables.

[0042] In this embodiment, the set S is illustrated as being for a free address table, but it goes without saying that the set S can be applied to ordinary tables and desks and can achieve the same effects as the above embodiment. [Explanation of symbols]
