Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a protective edge device for a top plate of a table or desk.

[Conventional technology and issues to be solved]

Conventionally, as a protective edge device for protecting the front edge of a top plate of an office desk, table, etc., a protruding step part that protrudes forward is formed at a lower position of the edge frame of the top plate. The end part of the edge frame including the part is covered with an edge member made of an integral skin form with an inverted L-shaped cross section.
It is disclosed in Publication No. 36087.

According to this prior art, the screw passed upward from the lower surface of the protruding step is simply fastened to the upper portion of the edge member, so that the lower surface of the upper portion of the edge member is connected to the upper surface of the protruding step. Even if the edge member is firmly attached, the lower part of the edge member is not engaged with the protruding step part, and the fact that the edge member is not in close contact with the lower part means that it is difficult to put your hand on the lower end of the edge member and press the desk. When the edge member is lifted, the lower part of the edge member tends to come off from the frame.

Therefore, in order to fix the lower part of the edge member to the protruding step, it is necessary to tighten the screws from inside the top plate so that the screws extend substantially parallel to the top plate of the top plate. There were problems in that the workability was poor and the number of screws increased, resulting in a disadvantage in terms of cost.

The present invention attempts to solve the problems that could not be solved with the prior art by devising the mounting location of the protective edge member that integrally covers the edge frame body.

[Means to solve the problem]

Therefore, in the present invention, a support plate portion projecting forward and a vertical side plate portion extending in a direction intersecting the support plate portion are formed on the edge frame body of a top plate of a desk or the like. is formed with a screw mounting portion that allows a screw to protrude diagonally upward and forward from between the support plate portion and the vertical side plate portion, and the protective edge member that covers the edge frame body is provided with a screw attachment portion that can protrude diagonally upward and forward from between the support plate portion and the vertical side plate portion. Contact surfaces are formed that face each other and extend in directions intersecting with each other, and the protective edge member is configured to be pulled in and tightened by a screw protruding from the screw attachment portion.

[Functions and effects of the idea]

According to this configuration, the support plate part and the vertical side plate part of the edge frame body extend in a direction that intersects with each other, and on the other hand, the pair of abutment surfaces of the protective edge member are also formed on the support plate part and the vertical side plate part, respectively. Since they extend so as to cross each other so as to face each other, when the protective edge member is tightened with the screw protruding from between the support plate portion and the vertical side plate portion, the protective edge member will be It is pulled toward both the support plate part and the vertical side plate part of the edge frame body so as to be in close contact with each other.

In other words, since the direction in which the screws are tightened is neither parallel to the support plate nor parallel to the vertical side plates, the force for tightening the screws can be applied in both directions simultaneously. Therefore, although the screws are tightened in one direction, the protective edge member can be firmly fixed in a state where it is supported by the support plate portion of the edge frame body and in close contact with the vertical side plate portions.

Further, since the screw attachment portion for the protective edge member is located on the lower surface side of the edge frame, the protective edge member can be easily attached with the top plate turned over, and the installation work is also facilitated.

In particular, the tightening work is extremely easy compared to the case where the screws are tightened so as to extend parallel to the top plate of the top plate.

The axis of the screw 11 extends in a diagonal direction that intersects with the direction in which the support plate 9a extends, and the axis of the screw 11 protrudes forward and obliquely from the screw mounting portion 10 (the support plate portion 9a
and the vertical side plate portion 9b).
Configure it as follows.

Therefore, holes (not shown) for screws (screws) 11 are provided in the seat surface 10a of the screw attachment part 10 and in the corners where the support plate part 9a intersects with the vertical side plate part 9b.

Reference numeral 12 denotes a left and right longitudinal protective edge member made of hard synthetic resin in the protective edge device;
are the support plate portion 9a and the vertical side plate portion 9b of the protruding step portion 9.
The outer surface of the protective edge member 12 is integrally covered with a covering member 13 made of soft synthetic resin. covered by a target or after-fitting.

This protective edge member 12 has a hollow shape with a horizontally L-shaped cross section, and the protective edge member 12 is provided on both surfaces of the support plate portion 9a and the vertical side plate portion 9b of the protruding step portion 9. Contact surfaces 12a, 12 facing each other
b, and the intersecting angle between the contact surfaces 12a and 12b is formed to be slightly narrower than the intersecting angle between the support plate portion 9a and the vertical side plate portions 9b.

Further, reference numeral 14 denotes a continuous rib extending outward from the intersection corner of both contact surfaces 12a and 12b of the protective edge member 12, and the continuous rib 14 includes:
A female threaded portion 15 for the screw 11 is formed.

Note that the vertical contact surface 12c of the protective edge member 12 facing the bent vertical plate 6 may be formed to extend upward at an angle slightly larger than 90 degrees with respect to the substantially horizontal contact surface 12a. good.

Therefore, when the protective edge member 12 is placed over the protruding step portion 9 as it is, at least the intersecting angle of the contact surfaces 12a, 12b in the mutually intersecting directions,
A slight gap is created between the support plate part 9a of the protruding step part 9 and the intersection corner of the vertical side plate part 9b, and the intersection corner of the substantially horizontal abutment surface 12a and the vertical abutment surface 12c and the support A gap also occurs between the intersection corner of the plate portion 9a and the bent vertical plate 6.
