Description

  The present invention relates to a lid plate opening / closing device for an underfloor storage using a gas spring. More specifically, the present invention relates to a cover plate opening / closing device for an underfloor storage that can adjust the opening / closing force steplessly without changing the type of the gas spring and is easy to adjust.

2. Description of the Related Art Conventionally, there is an apparatus disclosed in Patent Document 1 as an apparatus for adjusting the height of a table top using a gas spring. This device adjusts the push-up force with respect to changes in the load applied to the top plate, and can be performed without greatly changing the height of the top plate. Specifically, when the top of the desk is at a predetermined height position, the distance from the arbitrary position of the second mounting portion to the first mounting portion is the same, and one end of the gas spring Even if the attachment position to the second attachment portion is changed, the change in the height of the top plate is reduced. For this reason, even if the position of the second mounting portion is changed, the change in the height of the top plate is small, and the push-up force can be adjusted with respect to the change in the load on the top plate.
JP-A-11-127964

  In the adjustment of the push-up force with respect to the change in the load on the top plate in Patent Document 1, the push-up force changes stepwise because the attachment position of the second attachment portion varies stepwise (regulated by the position of the attachment hole). The adjustment work was troublesome. In particular, in the case of the storage case cover plate, there is a Japanese-style storage case where a tatami mat is applied as a load, and there is a case where almost no load is applied. In the present invention, the support base of the gas spring is sandwiched between the female screw pin and the male screw pin, and can be attached to the arcuate groove opening of the base at an arbitrary position. It is intended to provide a lid plate opening and closing device for the underfloor storage that can be adjusted steplessly.

In order to solve the above-described problems, the lid plate opening / closing device of the underfloor storage according to the present invention, as described in claim 1, supports the gas spring with the upper end pivotally attached to the rear surface of the lid plate and the base end as the support base. A cover plate opening / closing device for an underfloor storage, in which a base is clamped and fixed from both sides by a female screw pin and a male screw pin to an arc-shaped groove opening formed in a base with a pivot point as a base point. The male screw pin has a male screw on the outer periphery of the pin portion protruding from the head portion, and the female screw pin has a pin portion protruding from the head portion having the female screw on the inner periphery. it is clamped and held, in which the pin of the female screw pin is characterized that you have been projected in its head away from the base.

  The lid plate opening and closing device of the underfloor storage according to claim 1 is a circle in which a support base portion of a gas spring having an upper end pivotally attached to the back surface of the lid plate and a base end as a support base is formed on a base from the pivot attachment portion. Since the female screw pin and the male screw pin are sandwiched and fixed to the arc-shaped groove opening from both sides, the position can be moved by simply loosening the screw engagement between the female screw pin and the male screw pin. There is no need to separate them, and the adjustment work is easy. In addition, the support base of the gas spring is clamped and fixed from both sides by a female screw pin and a male screw pin to an arc-shaped groove opening formed in the base with the pivoting portion as a base point. It can move, and the push-up force can be adjusted steplessly.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an underfloor storage, wherein 1 is a main body and 2 is a cover plate. The lid plate 2 is connected to the main body 1 by an open / close link 3 and a gas spring 4. The opening / closing link 3 holds the lid 2 in a certain state when the lid 2 is opened, and is generally used. The gas spring 4 provides an auxiliary push-up force for facilitating opening of the cover plate 2.

  FIG. 2 is an enlarged view showing a connected state of the lid plate 2 and the main body 1, and the gas spring 4 is pivotally attached to the back surface of the lid plate 2 and the support base 5 is fixed to the base 6. The base 6 is fixed to the main body 1. The base 6 has an arcuate groove opening 8 with the pivot 7 as a starting point.

  FIG. 3 is an exploded explanatory view showing a state in which the support base 5 of the gas spring 4 is clamped and fixed by the female screw pin 9 and the male screw pin 10 to the arcuate groove opening 8 formed in the base 6. 1 shows an embodiment of a guide pin device according to the present invention.

  The female screw pin 9 and the male screw pin 10 are interposed between the arcuate groove opening 8 and the support base 5 of the gas spring 4 and screwed to fix them. In this case, a through hole 11 is formed in the support base 5 of the gas spring 4, and the female screw pin 9 and the male screw pin 10 are inserted through the arcuate groove opening 8 and the through hole 11 of the support base 5, The head is clamped and fixed. This clamping and fixing structure can be easily adjusted.

  That is, the adjustment operation is an operation of changing the mounting position of the support base portion 5 of the gas spring 4. In this clamping and fixing structure, the loose screw screw of the female screw pin 9 and the male screw pin 10 is simply moved along the arcuate groove opening 8. Thus, the mounting position of the support base 5 of the gas spring 4 can be changed, and adjustment work is easy. Further, the mounting position can be continuously selected steplessly within the range of the arcuate groove opening 8, and the push-up force can be adjusted without permission.

The perspective view of the underfloor storage concerning this invention. The enlarged view which shows the connection state of the main body and cover plate of the Example shown in FIG. FIG. 2 is an exploded explanatory view of the clamping and fixing unit of the embodiment shown in FIG. 1.
