Abstract

The utility model relates to a foldable foot rack for furniture, which is provided with a combining seat which can be combined with the bottom surface or the plated surface of the furniture and a foot post which is pivotally connected with the combining seat. The end portions of two tabs used for the foot post to be pivotally arranged are respectively formed with a hook mouth; the relative positions of the tube surface on both sides of the foot post are respectively penetrated with a through hole, and a hollow tube slot of the foot post is provided with an elastic clamping element which is provided with two clamping knobs which can be projected by a corresponding perforation respectively, which causes the foot post to be directly fastened at the position of the hook mouth of the combining seat by utilizing the two clamping knobs to form the foldable foot rack which can rapidly support the foot post in the way of unfolding and positioning or retract in the way of folding and backing as long as an operator directly wrenches the foot post.

Description

Apply to the foldable type foot rest of furniture

(1) technical field

The relevant a kind of foldable type foot rest that applies to furnitures such as a tool or chair tool of the utility model.

(2) background technology

For the harvesting that is convenient to various furnitures such as a tool, chair tool or cabinet and carry carrying, relevant dealer designs many kinds to have the support of launching and rolls over the foot rest structure that leans on closing function, its concrete structural form can hold and not give unnecessary details referring to announcing No. 327755 " table pin the simple and easy locating structure of amounting to ", bulletin No. 333003 " table pin folding location structure " as Taiwan and announcing shown in No. 396792 patent cases such as " the chair pin are amounted to the articulation structure improvement ".

Existing foldable type foot rest structure, general structural design is all comparatively complicated, manufacturing cost higher (as announcing No. 327755 and No. 333003 patent case), and when launching positioning supports or folding, all must push relevant blocking member, not only manipulate trouble inconvenience, and crushing operator's hand easily, is not appropriate design obviously.The chair pin of No. 396792 " the chair pin is amounted to the articulation structure improvement " patent case (to call in the following text with reference to case) of bulletin shown in Figure 5 is for another example amounted to articulation structure, with reference to case is to be provided with a ㄇ shape fixed mount 90 that can spiral shell be incorporated into furniture 50 bottom surfaces admittedly, this fixed mount 90 is provided with two ear seats 91, place with the kelly 93 at two ends, top for a V shape iron line chair pin 92 and to be hubbed in two ear seats, the 91 corresponding pivot holes 94, and respectively be provided with one for the locating hole 95 of iron wire chair pin 92 with the shaft blocking in the bottom side of two ear seats 91.

Though the overall structure with reference to case is also uncomplicated, but the structural strength of iron wire chair pin 92 is relatively poor, and as shown in Figure 6, in the time will folding iron wire chair pin 92, two shafts of the necessary iron wire of grip pressure simultaneously earlier chair pin 92, allow two shafts of iron wire chair pin 92 withdraw from locating hole 95 simultaneously, can finish the operation that folds of iron wire chair pin 92, the operation that not only two shafts of iron wire chair pin 92 will be withdrawed from symmetrically locating hole 95 simultaneously quite bothers, and as long as skew or firmly excessive a little, the problem that the kelly 93 of iron wire chair pin 90 must be reinstalled by 94 slippages of pivot hole just can take place, and manipulates trouble inconvenience considerably.

(3) utility model content

Because the above-mentioned existing structural design that applies to furniture foldable type foot rest is comparatively complicated or manipulate scarce fraud and restriction such as trouble inconvenience, main purpose of the present utility model provides a kind of easy easily foldable type foot rest of manipulating.

Based on aforementioned purpose, foldable type foot rest of the present utility model is provided with a connecting support, this connecting support is provided with one can be incorporated into a tool, the board of various furnitures bottom surfaces such as chair tool or cabinet or plate face, stretch the auricle of establishing two spaced and parallel down in this board, and utilize a bolt that the pivot joint of one socle is incorporated between two auricles, the main architectural feature of the utility model is: to being less than the wherein recessed mouth of hook that forms of end horizontal of an auricle, the degree of depth of this mouth of hook surpass this bolt under, and in the top side of the mouth of hook and the bottom side be formed with the prominent edge clipping that an arc protrudes towards mouth of hook direction slightly along the guiding edge and of shape respectively; This socle provides a perforation corresponding to the mouth of hook in the pipe face with respect to the position of the mouth of hook, and has installed a spring clamping part in the tube seat of socle, and this spring clamping part is provided with a V-arrangement elastic portion, and being formed by the end of this V-arrangement elastic portion can be by the outstanding card button of corresponding perforation.

The utility model overall structure is quite simplified strong, and socle can utilize the card button of spring clamping part directly to be snapped in the mouth of hook place of connecting support, the operator is as long as directly pull socle, can apace socle be formed expansion positioning supports or folding by folding, manipulate suitable easy to be light power, dark tool industrial utilization.

Understand the purpose of this utility model, characteristics and advantage for clearer, preferred embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
