Description

  The present invention relates to a panel support leg that is preferably used in an office or the like.

  In recent years, tables have been developed that can respond swiftly to changes in organization and layout changes due to changes in the number of people, and also can be used for various purposes such as fixed seats, free addresses, and meeting tables. However, if a desktop panel, a side panel, or the like is attached to such a table as an option, there may be a problem in changing the usage mode of the table.

  That is, since conventional desktop panels, side panels, etc. are generally attached to a table using a fixture such as a clamp, it is troublesome to remove and attach the desktop panel etc. when changing the usage mode of the table. It is often the case.

  In addition, there is also one in which a panel is simply placed on a top plate via panel support legs (for example, refer to Patent Document 1). However, the conventional panel support leg is attached to the leg body in a state where the leg blades are fixed, and the leg blades are provided in a posture orthogonal to the surface of the panel. If the panel with the panel support legs attached is stored as it is, there is a problem that the volume becomes high and the storage efficiency becomes low. For this reason, in the conventional case, the leg blades are often removed when the panel is stored, but it may be troublesome to attach and detach the leg blades during storage and reuse.

  Further, the circumstances described above are applicable not only to the panel support legs used for the panel used on the top plate but also to the panel support legs supporting the panel installed on the floor surface such as a tiling.

The rattling projections 121 have a shape in which the protruding width from the facing surface 12a becomes larger as it goes downward in order to facilitate the insertion of the panel P and to prevent the panel P from being pulled out upward. ..

  As shown in FIGS. 1 to 13, the leg blade 2 includes a central portion 21 that supports the bottom plate portion 11 of the leg body 1, and a blade portion 22 that extends outward from the central portion 21. is there. The central portion 21 has a disc shape corresponding to the bottom portion 11, and has a sliding contact surface 2a on its upper surface that is in sliding contact with the lower end of the leg body 1. As shown in FIG. 11, an annular guide ridge 211 slidably fitted in the guide groove 113 is formed on the sliding contact surface 2a. That is, by slidably fitting the guide ridges 211 in the guide grooves 113, the leg blades 2 can swivel around the swivel axis with respect to the leg body 1. ..

  As shown in FIGS. 4, 8, 9 and 10, the moderation mechanism 3 is provided in the leg body 1 and the cam body 31 having a plurality of moderation recesses 313 and the leg blades 2. It is provided with a moderator 32 that selectively engages with the moderation recess 313 as the leg blades 2 rotate with respect to the leg body 1.

  As shown in FIGS. 7 to 10, the cam body 31 is a disc-shaped member having the sliding contact surface 1a on one surface side and the through hole 311 penetrating from the one surface side to the other surface side. As described above, the cam body 31 also serves as the lower layer portion 111 of the bottom plate portion 11 of the leg body 1. A cam surface 312 including the moderation recess 313 is formed on the inner circumference of the through hole 311. That is, the cam surface 312 is formed between a plurality of, specifically, four moderation recesses 313 arranged at a constant pitch around the pivot axis of the leg blade 2 and between these moderation recesses 313. And a guide portion 314. The guide part 314 guides the moderator 32 moving between the moderation recesses 313, and has a curved shape such that the central part thereof is closest to the turning axis C. The shortest distance between each of the guide portions 314 and the turning axis C is set to be shorter than the shortest distance between each of the moderation recesses 313 and the turning axis C. Further, the cam body 31 is a cavity for encouraging the portion where the guide portion 314 is formed outside the respective guide portions 314 to elastically deform and move in a direction away from the turning axis C. 315 is provided.

  As shown in FIGS. 7 to 11, the moderator 32 is provided so as to protrude inside the guide protrusion 211 on the central portion 21 of the leg blade 2, more specifically, on the sliding contact surface 1a. .. The moderator 32 has a claw shape having an arrowhead portion 322 at the upper end, and four moderators 32 are arranged at a constant pitch so as to surround the turning axis C. More specifically, the detent 32 has a substantially prismatic detent body 321 which is slidably contacted with the cam surface 312 and selectively engages with any one of the detent recesses 313, and an upper end of the detent body 321. The arrow head portion 322 is provided, the base end portion of which is provided outwardly protruding from the outer surface of the moderator body 321 and the upper end portion of which is sharpened. The arrowhead portion 322 is engaged with the upper surface of the cam body 31 to prevent the leg blades 2 from separating from the leg body 1. The leg blades 2 are attached to the leg body 1 by engaging the moderator 32 and the cam body 31 by utilizing the elastic deformation of the member.

  By attaching the panel support legs L as described above to the lower end portions of the panel P in the vicinity of both ends thereof, as shown in FIG. 1, the panel P is placed on the top plate T1 of the table T in an upright posture, for example. Can be placed.

  As shown in FIG. 14, the table T has a square shape in a plan view, and a top plate T1 having a wiring insertion window T11 having a square shape in a plan view in a central portion 21, and a movably supporting the top plate T1. The panel support leg L is used mainly in a state of being placed on both sides of the wiring insertion window T11, respectively. A pair of wiring covers T12 and T13 are openably and closably arranged in the wiring insertion window T11. These wiring covers T12 and T13 are shown in FIG. 1 and FIG. 14 in which the rotating ends T12a and T13a are arranged opposite to each other and the rotating ends T12a and T13a are opposed to each other. It is detachably attached to the wiring insertion window T11 so that such an inward opening mode can be selectively adopted. In the outside opening mode, a gap is formed between the wiring covers T12 and T13 and the opening edge of the wiring insertion window T11 in a closed state so as to form a substantially annular shape in a plan view, and the inside opening is performed. In the aspect, the gaps T14 and T15 are formed so as to form a substantially H shape in a plan view.

  Next, the operation of the panel support leg L will be described.

  When the panel P is supported as shown in FIG. 1, as shown in FIG. 10, the detent element 32 engages with each detent recess 313 and is in a stable posture, that is, the leg blades 2 with respect to the panel P. And in other words, in a posture in which the holding groove 1m extends in a direction orthogonal to the opening direction.

  From this state, when the leg blades 2 are horizontally swung with respect to the leg body 1, each detent 32 is disengaged from the corresponding detent recess 313 and moves while pressing the guide portion 314. At that time, as shown in FIG. 13, the portion where the guide portion 314 is formed is elastically deformed toward the outside, that is, the side where the cavity 315 is formed, while allowing the movement of the moderator 32. Will be done. When the moderator 32 reaches the adjacent moderation recess 313, the elastic deformation of the cam body 31 and the moderator 32 is minimized, and the leg blades 2 are stopped at that position and are stably held. Therefore, when housing the panel P, as shown in FIG. 14, each leg blade 2 extends in a posture parallel to the panel P, that is, in a direction parallel to the opening direction of the holding groove 1m. By pivoting and holding the panel P in the posture, it is possible to efficiently store the panel P without removing the panel support leg L.

  With such a configuration, the leg blades 2 can be swung in different postures with respect to the leg body 1 and stably held. Therefore, by changing the moderation stop position of the leg blades 2 when using and when storing, it is possible to take a posture suitable for each case, and not only the supporting performance at the time of use but also when storing. The storage efficiency and the like can be reasonably improved. Further, if this panel support leg L is stored without being removed from the panel P, it is possible to quickly respond to reuse, and the panel support leg L separated from the panel P is separated and lost. It is also possible to prevent the occurrence of such problems.

  Further, in the embodiment described above, the leg blades 2 can be attached to the leg body 1 by using the cam body 31 and the moderator 32 that configure the moderating mechanism 3, so the number of parts is increased. And the number of assembling steps can be reduced without difficulty.

  Further, since the holding groove 1m for supporting the lower end portion of the panel P is formed between the pair of standing portions 12 of the leg body 1, the panel P is attached to the panel P by a simple operation of inserting the panel P into the holding groove 1m. Support legs L can be attached.

  In addition, the cam body 31 having the moderation recess 313 provided in the leg body 1 and the moderation selectively engaged with the moderation recess 313 as the leg blade 2 pivots with respect to the leg body 1 are provided. Since the detent mechanism 3 is configured by using the child 32, the leg blades 2 are placed in a posture orthogonal to the panel P by a simple configuration in which the detent 32 is engaged with any one of the detent recesses 313. The mode can be stopped in any of the postures parallel to the panel P.

  In addition, a cam surface 312 including the moderation recess 313 and the guide portion 314 is formed on the inner periphery of the through hole 311 of the cam body 31, and the moderator 32 is arranged inside the through hole 311. Therefore, when the leg blades 2 are swung with respect to the leg body 1, the guide portion 314 of the cam surface 312 is used to guide the moderator 32 with a simple configuration.

  Then, the shortest distance between each of the guide portions 314 and the turning axis C is set to be shorter than the shortest distance between each of the moderation recesses 313 and the turning axis, and the cam body 31 causes Since the cavity 315 is provided on the outer side of the guide portion 314 for promoting elastic deformation in a direction away from the pivot axis of the portion where the guide portion 314 is formed, that is, outside, the leg blades 2 are attached to the leg body. A configuration in which the guide portion 314 of the cam body 31 retreats outward and guides the moderator 32 can be realized without difficulty when the armature 1 is turned.

  Next, a second embodiment of the present invention will be described below with reference to FIGS.

  The panel support leg LL of the present embodiment is also used to support the desktop panel P on a top plate such as a movable table. Hereinafter, differences from the panel support leg according to the first embodiment will be described. Note that, except for the points described below, the configuration is similar to that of the first embodiment described above, so the same or corresponding parts will be assigned the same reference numerals and detailed description thereof will be omitted.

  In the present embodiment, the upper surface of the upper layer portion 112 of the bottom plate portion 11 of the leg body 1 is substantially flat. In other words, in the present embodiment, the positioning protrusion that pierces the lower end of the panel P is not provided.

  As shown in FIGS. 15 and 18, the leg blade 2 has a meat-throw-in portion 2n on the lower surface and grounding bodies 23 near both ends in the longitudinal direction of the lower surface.

  As shown in FIG. 16, the moderation mechanism 3 includes four moderation recesses 313 and two moderators 32 that are selectively engaged with the moderation recesses 313. The cam surface 312 provided with the four moderation recesses 313 has a shape similar to that according to the first embodiment. On the other hand, as shown in FIGS. 16 and 17, the moderator 32 is a semi-cylindrical body in which the portion slidingly contacting the cam surface 312 forms a cylindrical surface.

  With such a structure, not only can the same operational effects as those of the panel support leg of the first embodiment described above be obtained, but also the structure of the moderation mechanism 3 can be simplified to further improve durability. It becomes possible to raise.

  In addition, in the said embodiment, although the case where several moderator was provided mutually mutually spaced apart was demonstrated, like panel support leg L2 shown in FIG. 19 and panel support leg L3 shown in FIG. The moderator 32 may be integrally formed. Further, the number of the moderation elements 32 and the moderation concave portions 313 may be any number as long as it is two or more, and can be variously changed as necessary. FIG. 20 shows an example provided with six moderators 32 and six moderation recesses 313. The panel support leg L2 and the panel support leg L3 described with reference to FIGS. 19 and 20 have the same configuration as the panel support leg L according to the above-described embodiment, except for the points described above. Corresponding parts are designated by the same reference numerals, and detailed description will be omitted.

  Furthermore, the present invention is not limited to the embodiments described above, and various modifications can be considered.

  For example, in the above-described embodiment, the leg body is provided with a cam body having a plurality of moderation recesses, and the leg blade selectively engages with the moderation recess as the leg blade pivots with respect to the leg body. However, conversely, the leg blade is provided with a cam body having a plurality of moderation recesses, and the leg body is selectively formed in the moderation recess as the leg blade rotates with respect to the leg body. Of course, it is possible to adopt a mode in which the interlocking moderator is provided.

  In the above embodiment, the leg body has a shape inscribed in a virtual frusto-conical shape having a diameter slightly larger than the thickness dimension of the panel, but the leg body may have any shape. As a specific shape of the leg body, for example, a shape that is inscribed in a virtual prism shape or a virtual pyramid shape having a dimension slightly larger than the thickness dimension of the panel can be considered.

  In the above-described embodiment, the leg body is provided with the bottom plate portion that also serves as the cam body of the moderation mechanism, and the pair of upright portions protruding upward from the bottom plate portion, and the panel is provided between the pair of upright portions. Although the holding groove for holding the lower end of the leg has been described, the leg body may have any configuration. As a specific configuration of the leg body, for example, a bottom plate portion and four standing portions that project upward from the bottom plate portion and are spaced apart from each other by 90 ° in the circumferential direction are provided. It is conceivable that a panel insertion space is provided for inserting and holding the panel.

  In the above-described embodiment, as described above, the cam surface including the moderation recess is formed on the inner periphery of the through hole of the cam body, and the moderator is arranged inside the through hole, so that the leg has a simple structure. While the guide part of the cam surface is used to guide the moderator when the blade is rotated with respect to the leg body, the configuration, shape and arrangement of the cam body and the moderator may be set arbitrarily. .. More specifically, in the above-described embodiment, the cam surface is configured to have a simple structure so that the moderator can be guided by using the guide portion of the cam surface when the leg blade is rotated with respect to the leg body. And the guide portion is formed on the cam body while the shortest distance between the guide portions and the turning axis is set shorter than the shortest distance between the moderation recesses on the cam surface and the turning axis. Although a cavity is provided for promoting elastic deformation in a direction away from the turning axis of the part, that is, outward, a configuration other than this may be adopted. For example, a mode may be adopted in which a space is provided inside the detent to promote the elastic deformation of the detent while moving toward the turning axis.

  In addition, various modifications may be made without departing from the spirit of the present invention.
