Description

  The present invention relates to a desk suitably used in a school or office.

  Conventionally, various desks that can be easily moved by a user in a school or office have been proposed (see, for example, Patent Document 1). Such desks are suitably used as so-called lecture desks, particularly in educational institutions such as schools. Students who mainly use these desks often carry these desks to a desired position and use them according to the situation and form of classes and work. Therefore, in recent years, these desks have been made lighter than ever so as to be easily carried by users.

  However, desks that have been used in schools, etc., may be more burdensome than expected by the user, depending on the position that they hold when carrying them. That is, even if the desk is lightened as described above, it is not necessarily directly related to the ease of transportation for the user.

Utility Model Registration No. 3114585

  The present invention focuses on the above-described points, and an object thereof is to provide a desk that effectively improves the ease of carrying for a user.

  In order to achieve such an object, the present invention takes the following measures.

That is, the desk according to the present invention is a desk having a top plate and a top plate support arm that supports the lower surface of the top plate and is supported by the legs from below, and is one of the lower edges of the top plate support arm. It is characterized in that a handle portion is provided for allowing the user to grip the portion by denting the portion toward the lower surface of the top plate.

  In such a case, when the user moves the desk by lifting it up by hand, the user is naturally prompted to grasp the handle portion. Therefore, the user effectively avoids carrying and moving in various postures by grasping different places, and is urged to carry every desk in the same system. As a result, the work of carrying and moving can be performed stably.

  As a specific mode that the user can easily hold by turning his / her hand from the upper side of the top plate, it is desirable to position the handle portion in the vicinity of the side edge portion of the top plate.

  In addition, if a raised portion formed by raising the periphery of the handle portion is provided, the user can easily recognize the handle portion by groping without looking directly at the handle portion.

  In addition, in order to effectively balance the strength as a desk and the ease of holding the handle, the top plate support arm has an arm main body attached to the top plate, and a cover that covers the arm main body from below. It is desirable to form a handle on this cover.

  And when the base end of the arm main body of the desk and the upper end of the leg are connected, the connection point between the arm main body and the leg column appears at the base end of the arm main body. However, if the connecting portion concealing portion that can conceal at least a part of the connecting portion between the arm main body and the leg support is provided, the design of the connecting portion can be facilitated. Further, post-processing for improving the appearance can be simplified.

In particular, if this concealing part concealment part has a curved shape that is continuous between the surface of the arm body and the surface of the leg body, it is possible to smoothly move from the leg strut to the handle part when trying to hold the handle part. A hand can be guided, and an apparent sense of unity between the leg support and the top support arm can be induced.

  As a specific configuration for effectively improving the mounting strength of the cover to the arm body, a cross-sectional view of the arm body with the horizontal wall in close contact with the top plate and the standing wall that makes a pair from both sides of the horizontal wall is suspended downward. It is desirable that the cover has an additional wall that is in close contact with or close to the inner surface of the standing wall and a cover plate that covers the arm body from below.

  According to the present invention, when the user moves the desk by lifting it up by hand, the user is naturally prompted to grasp the handle portion. As a result, it is possible to provide a desk that can stably carry out and carry work.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The desk 1 that is furniture according to the present embodiment is preferably used in educational institutions and facilities such as universities. Especially in educational institutions, it is used as a so-called “lecture desk”.

  The desk 1 has a desk main body 2 that is a furniture main body in which the top plate support arm 5 supports the top plate 4, and a leg body 3 that supports the top plate support arm 5. The leg 3 is rigidly connected to the top support arm 5 via an arm connection portion 71 which is a welded joint, thereby supporting the top support arm 5 and a lower end of the leg support 7. On the side, it has a leg base 8 for maintaining the standing state of the leg strut 7 by being rigidly connected via an arm connecting portion 72 which is also a welded joint. The leg support 7 is made of a metal pipe material, and its cross-sectional view has a substantially elliptical shape that is long in the front-rear direction. In the present embodiment, the base end portion (small edge) of the top support arm 5 is brought into contact with the upper end portion of the leg column 7 from the surface side of the leg column 7 and connected via the arm connection portion 71. The top plate support arm 5 and the leg support 7 are connected so as to form an obtuse angle. Moreover, the top-plate support arm 5 and the leg column 7 have different cross-sectional shapes.

  Further, in this embodiment, as shown in part in FIG. 2, the shape of the curtain plate 9 installed between the leg posts 7 is changed from a normal steel plate type to a lightweight translucent resin curtain plate 9a. It has become possible. Although not shown in the drawings, the desk 1 can be used as a desk 1 according to the color of the space into which the desk 1 is introduced by appropriately selecting the colors of the top plate 4, the legs 3 and the curtain 9. It is possible to have a sense of unity.

Here, the desk 1 according to the present embodiment is provided with a handle portion 56 for allowing the user to grip the part by lowering a part of the lower edge of the top plate support arm 5 toward the bottom surface of the top plate. It is a feature.

  Hereinafter, the configuration of the desk 1 will be specifically described with reference to FIGS. 1 to 11.

  As shown in FIGS. 1 to 4, the top plate 4 is a rectangular shape having a size that can be used by a single user in the present embodiment, and along the side edge 4 b on the back (lower) surface side. Between the arm mounting portion 41 for mounting the pair of top plate support arms 5 and the arm mounting portion 41, the shelf mounting for mounting the luggage storage shelf 6 for storing the user's luggage under the top plate 4 The part 42 is formed. The top plate 4 is also provided with a surface process (not shown) that makes it difficult for dirt to adhere to the upper surface and the side surface.

  The top plate support arm 5 is attached to the vicinity of both side edges 1b of the top plate 4 by, for example, screwing via an arm attachment portion 41. The top plate support arm 5 is attached to the arm main body 50 that is directly attached to the top plate 4, an arm cover 51 that covers the arm main body 50 from below, and the arm main body 50. And a hook 52 for suspending and holding a user's bag or the like.

  In this embodiment, the hook 52 is made of, for example, a translucent resin material and is screwed to the hook mounting portion 54 of the arm body 50. Of course, as the specific shape and material of the hook 52, various existing ones can be applied, and therefore a specific description will be omitted in this embodiment.

  The arm main body 50 has a U-shaped cross-sectional view formed by bending a sheet metal material, for example, and includes a horizontal wall 50a that is in close contact with the back surface of the top plate 4 and a pair of standing walls 50b that are suspended from both ends of the horizontal wall 50a. Is formed in a part of the base end side welded to the leg strut 7 with a recessed portion 50c in which the standing wall 50b is slightly recessed upward, and the tip edge is inclined from the lower end. It is comprised so that it may continue to the horizontal wall 50a. The arm body 50 has a top plate mounting portion 53 formed by providing an opening through which a screw is inserted into the horizontal wall 50a, and a plurality of screw holes provided in a middle portion in the front-rear direction of the inner standing wall 50b. A hook mounting portion 54 for fixing the hook 52 to the hole and a cover mounting portion 55 for fixing the arm cover 51 using both standing walls 50b are provided. The cover mounting portion 55 is composed of mounting holes 551 in which two standing walls 50b constituting the recess 50c are opened in total at four locations, and by receiving mounting projections 59 described later provided on the arm cover 51, Position the arm cover 51 securely.

  The arm cover 51 includes an additional wall 51a that is in close contact with or close to the inner side surface of the standing wall 50b of the arm body 50, and a covering plate 51b that covers the arm body 50 from below. Since the additional wall 51a formed is positioned between the standing walls 50b of the arm, the arm cover 51 can be attached to the arm main body 50 without shaking in the width direction. A connecting rib 51c for connecting the attachment wall 51a is formed at the tip of the arm cover 51. Further, a plurality (two in this embodiment) of the connecting ribs 51c are formed at a certain distance from the tip of the covering plate 51b. As a result, even if the arm cover 51 is made of a translucent resin material, the screw provided to the top plate mounting portion 53 and the hook 52 mounting portion even when the arm cover 51 is viewed from the tip edge 50d side when the arm cover 51 is mounted. Etc. are suitably concealed without being visually recognized.

  The arm cover 51 has a handle portion 56 formed to be recessed above the other portion on the base end side, that is, close to the top plate 4, and the periphery of the handle portion 56 is raised. The raised portion 57 formed in this way, the curved concealment portion 58 that is a connection portion concealment portion formed further on the proximal side than the handle portion 56, and inwardly formed at four locations inside the handle portion 56. And a protruding mounting projection 59. The raised portion 57 raises a portion surrounded by the raised portion 57 by raising the periphery of the handle portion 56, specifically, the side of the handle portion 56 and the resin on the tip side, that is, the portion of the covering plate 51b. The user can easily recognize it. The curved concealing portion 58 covers the upper end side of the leg strut 7 and the proximal end side of the arm main body 50 while concealing especially the corner portion of the arm connecting portion 71 which is a welded joint. It is shaped so as to be in close contact with the arm body 50 while being bent from the close end. Thereby, in the state which attached the arm cover 51, it forms so that the top-plate support arm 5 and the leg support | pillar 7 may make the external shape which continues smoothly.

  Therefore, the desk 1 according to the present embodiment forms the handle portion 56 by partially denting the covering plate 51b of the arm cover 51 upward. The handle portion 56 is formed on both side edges 1b below the top plate 4 and in the vicinity of the counter-use end. Therefore, when the user has the handle portion 56, the hand is turned from above the top plate 4, and the finger is extended downward from the state where the palm portion is placed on the top surface of the top plate 4, so that the four parts other than the thumb. The handle portion 56 can be grasped with a finger. By doing so, the user can firmly hold the top plate 4 and the handle portion 56 using the entire hand. In addition, the surface of the handle portion 56 forms an anti-slip 561 in which the resin bulges in the form of dots formed intermittently so that the user's finger does not slip.

  In the case of the desk 1, the desk body 2 has a top plate support arm 5 because the leg body 3 is connected to the leg body 3 in an L shape when viewed from the side from a position near the side view opposite use edge 1 a of the top plate 4. In this case, the center of gravity in the front-rear direction is greatly biased toward the counter-use edge 1a. Therefore, the handle portion 56 according to the present embodiment is formed at a position that coincides with the center of gravity of the top plate 4 on both sides and in the front-rear direction. Thereby, when the user who holds the handle portion 56 with both hands lifts the desk 1, the balance is hardly lost, in other words, the desk 1 can be lifted with little wobbling.

  On the other hand, the leg support 7 constituting the leg 3 forms an arm connecting portion 71 connected by welding to the top plate support arm 5 at the upper end, and is also based on the leg base 8 constituting the leg 3 at the lower end. They are integrally connected by welding through the connection portion 72. Further, for example, a resin grounding plate 73 is attached to the lower surface of the lower end portion so that the floor surface can be installed without damaging the floor surface. In the present embodiment, the base end portion (small edge) of the leg base 8 is brought into contact with the lower end portion of the leg column 7 from the surface side of the leg column 7 and connected via the arm connection portion 72. The leg base 8 and the leg support 7 are connected to form an acute angle. The leg base 8 and the leg support 7 have different cross-sectional shapes.

  The leg base 8 includes a base body 80 integrally connected to the leg support 7, a base body 80, a cover that can removably cover the upper surface of the base body 80, that is, a base cover 81, and the base body 80. And an adjuster 82 which is a grounding portion which is screwed to the front end edge and is grounded to the floor surface.

  The base body 80 is formed in a substantially cylindrical shape by appropriately bending a sheet metal material, and has a bowl shape that is vertically long in cross section. Specifically, the upper surface is a curved surface 80a formed by bending a sheet metal, and the lower surface 80b having an inverted V-shape in cross-section is welded by bending ends of the curved surface 80a bent at acute angles. Is forming. Since the base body 80 is cylindrical, the leading edge 80c is formed so that the end surfaces of the curved surface 80a and the lower surface 80b appear as they are. On the other hand, the base end edge having a similar cross-sectional shape substantially equal to the front end face 80c is welded to the leg support 7 from the surface side via the arm connecting portion 72 as described above. Then, a cover mounting portion 83 is formed on the upper surface of the base body 80 by opening a total of four locations from the proximal end, and a plate nut is welded to the lower surface 80b in the vicinity of the distal end edge 80c. The adjusted adjuster mounting portion 84 is provided.

  The base cover 81 is made of, for example, a translucent resin made of the same material as that of the arm cover 51 and having a substantially U shape in cross section. The base cover 81 has a curved concealing portion 85 as a connecting portion concealing portion that extends the surface upward on the base end side to conceal the base attaching portion, and from the vicinity of the curved concealing portion 85 to the inner surface side in the longitudinal intermediate portion. The mounting projections 86 projecting at four locations and the lower stepped portion 87 formed in a step shape from the upper surface of the base body 80 at the lower end portion of the resin by covering the upper side of the lower end of the base body 80 over substantially the entire longitudinal direction. A tip concealing portion 88 that covers and conceals the tip edge of the base body 80, and an opening provided in the resin protruding from the center of the tip concealing portion 88. A shaft receiving hole 89 that can receive the mounting shaft 822 is provided. The curved concealing portion 85 covers the lower end side of the leg strut 7 and the base end side of the base body 80 while concealing especially the corner portion of the base connecting portion 72 which is a welded joint. It is shaped so as to be in close contact with the base body 80 while being bent from the close end. As a result, when the base cover 81 is attached, the leg base 8 and the leg support 7 are formed so as to form a smoothly continuous outer shape. The attachment protrusion 86 is used to position the base cover 81 with respect to the base body 80 by fitting into the cover attachment portion 83 from both sides. The downward step portion 87 positions the lower end portion of the cover together with the surface of the base main body 80 in a step shape, so that the base cover 81 can be removed from any position of the downward step portion 87 when the base cover 81 is replaced or removed. Can be removed. As described above, the tip concealing portion 88 has a smooth partial spherical shape on the surface side, and has an end face accommodating portion 881 and a V ground 882 that can accommodate the tip edge 80c on the inner side. The shaft accommodating hole 89 is set so as to be interfered with the mounting shaft 822 in a state where the mounting shaft of the adjuster 82 is accommodated, and the movement of the base body 80 in the longitudinal direction is prohibited.

  Thus, in the present embodiment, the upper surface of the base body 80 extends obliquely downward from the leg support 7, and the leg base 8 is positioned at a predetermined mounting position with respect to the base body 80.

  That is, as shown in FIGS. 9 to 11, in this embodiment, when the base cover 81 is attached to the base body 80, first, the base edge of the base body 80 is moved from an angle slightly raised at the base end side of the base cover 81. Then, the first engaging portion is engaged by pressing the base end side of the base cover 81 downward as shown in FIG. Further, by screwing the ground plate of the adjuster 82 upward, the mounting shaft 822 is moved upward and the tip is accommodated in the shaft accommodation hole 89. At the same time, the base cover 81 is reliably positioned in the vertical direction by contacting the V-shaped surface 882 from above the V-shaped lower surface 80b of the base body 80.

  With the configuration as described above, the desk 1 according to the present embodiment is provided with the handle portion 56 as described above, so that the user can move the desk 1 by lifting the hand 1 or the like. Since the user is naturally encouraged to grasp the handle portion 56, the user effectively avoids carrying and moving in various postures by grasping different locations. You will be urged to carry in the same system. As a result, the work of carrying and moving can be performed stably.

  In particular, in the present embodiment, since the handle 56 is positioned at the center of gravity of the desk 1 in the front-rear direction, the lifted desk 1 is stabilized, and as a result, labor-saving carrying is realized.

  In addition, in this embodiment, the surface of the handle portion 56 is placed on another surface of the top support arm 5 as a specific configuration of the handle portion 56 that is difficult to shift when the user's hand is lifted and is easy to hold stably. It is formed to be recessed upward so that it is closer to the top plate 4 than the place.
