Abstract

A safety fixing device for drawers is provided to keep a fixing position when an actuation tool is moved in a hole or a groove through an actuation shaft provided in an actuation plate, by providing the locking plate to be vertically movable by the actuation tool through a locking bar at the inside of a steel furniture body and by forming a dog-legged or an inverted dog-legged hole or groove in the actuation tool and providing the actuation shaft formed in the actuation plate fixed to the locking plate so as to engage with the hole or the groove, in the steel furniture such as a cabinet or the like retractably housing a plurality of stages of drawers. The safety fixing device for drawers does not require catch members and which is hard to break and can cope with any commodities by changing the entire size of a dog-legged hole or groove.

Description

The safe locking device of drawer

Technical field

The present invention relates to the drawer safe locking device on the iron furniture such as cabinet, relate in particular to 1 drawer when pulling out, all the other drawers still are locked in and push the safe locking device of using on the position.

Background technology

Drawer safe locking device on a kind of traditional cabinet (see Japanese Utility Model register No. 2576437) is arranged, as shown in Figure 6, but be the inboard start plate 11 that moves up and down freely that vertically is provided with in the cabinet main body of the multi-layer drawers of interior dress push-and-pull, a plurality of tipper cams 12 are set on above-mentioned start plate 11, simultaneously corresponding each tipper cam 12, on each drawer, be convexly equipped with the engagement pin that engages with tipper cam 12, thus when 1 drawer is pulled out, above-mentioned start plate 11 is to all the other drawer locks are moved pushing locational latched position, also in the cabinet main body, be provided with above-mentioned start plate 11 is remained on locking latch component 13 on the latched position, be characterized in, above-mentioned locking latch component 13 is arranged to and can be moved up and down above-mentioned start plate 11 being remained on the lock bolt position on the latched position and break away between the top position of this position, and on above-mentioned cabinet main body, the handover operation portion that can switch the position of this locking latch component 13 from the outside is set.

Yet, when adopting aforementioned Japanese Utility Model to register the disclosed conventional art of No. 2576437 communique, if all be in when pushing the position at whole drawers during cabinet cabinet is turned upside down in carrying, though the start plate can move from the latch-release position to latched position because of deadweight, but because of locking latch component is configured to and can moves the start plate being remained on the lock bolt position of latched position and break away between the top position of this position, and the cabinet main body is provided with the handover operation portion that can switch the position of locking latch component from the outside, though so by handling the position that locking latch component is switched in handover operation portion, can control locking and disengaging between start plate and the locking latch component at an easy rate, but, use locking latch component for the member with the drawer release mechanism moves up and down jam plate and keeps.Like this, locking latch component must be set, in order to adapt to different jam plate weight, must prepare multiple locking latch component, and, also will prepare multiple locking latch component in order to adapt to the different distances that move up and down of different commodity as the different cabinets of commodity in order just to lock.

Summary of the invention

In above-mentioned situation, the object of the present invention is to provide the safe locking device of drawer, it is simple in structure, need not locking latch component, even the weight of the jam plate that moves up and down changes according to different commodity, also can adapt to all commodity by changing spring strength.And the distance that moves up and down (size) also can be by changing The overall dimensions of shape hole or groove and adapt to all commodity.

To achieve these goals, the present invention adopts following technical scheme: but on the iron furniture such as cabinet of the multi-layer drawers of interior dress push-and-pull, the inboard operation that vertically is provided with by locking bar at iron furniture body moves up and down actuator, can move up and down jam plate freely therefrom, forms on actuator Shape or reverse

Shape hole or groove in order to engage with this hole or groove opposite, are being fixed in the reverse of described jam plate central portion with fixed axis

Shape or The top of the start plate of shape is provided with action shaft, an end of mounting spring below the start plate, and on jam plate the other end of fixing spring, in described hole or groove, moving when jam plate is moved, keep latched position by being located at action shaft on the start plate.Move in the groove and when jam plate is moved, keep latched position.

That is, the safe locking device of drawer has the mechanism of safety locking, that is, have make about the start member, move left and right and make it up and down or about the mechanism that keeps of temporary transient locking.

The specific embodiment

Below in conjunction with description of drawings one embodiment of the invention.

Describe safe locking device one embodiment of drawer of the present invention earlier in detail in conjunction with Fig. 1～Fig. 4.Fig. 1 is the exploded perspective view of the safe locking device major part of drawer of the present invention, the safe locking device of the drawer of expression topmost.Fig. 2 is each part assembling that expression will be shown in Figure 1 and jam plate is fixed on the cutaway view of the state behind the top, Fig. 3 be the A-A of Fig. 2 to view, Fig. 4 is the front view of expression with the state of jam plate after the bottom is fixed.

But for example on the interior cabinet main body 1 of adorning not shown 2 layers of push-and-pull drawer up and down, cabinet main body 1 inboard vertically be provided with actuator 3 move up and down and the jam plate 2 that moves up and down on actuator 3, form

Shape (as shown in FIG.) or reverse The hole of shape or groove 4.

In order to engage with the hole or groove 4 opposites of this actuator 3, the central portion of jam plate 2 be provided with fixed axis 7 fixing oppositely Shape (as shown in FIG.) or Shape start plate 5.And the action shaft 6 engage with the hole or the groove 4 of actuator 3 is set above this start plate 5, below an end of mounting spring 8 then, the other end of this spring 8 is fixed on the jam plate 2.

Adopt said structure,,, make it to be positioned in case make jam plate 2 move to the top as Fig. 2, shown in Figure 3

The top of shape hole or groove 4, the start plate 5 that is fixed on the jam plate 2 with fixed axis 7 promptly will be moved upward, and the action shaft 6 that is arranged on start plate 5 tops is just along actuator 3

Shape hole or groove 4 move to top.So, the spring 8 that is fixed on start plate 5 belows promptly is stretched, and the back that averages out keeps halted state in this position.Thereby, can not bring into play same effect even locking latch component is not set in addition yet.

In addition,,, the start plate 5 that is fixed on the jam plate 2 is moved downwards downwards downwards, make action shaft 6 along actuator 3 with regard to the tensile force that overcomes aforementioned spring 8 in case jam plate 2 is moved Shape hole or groove 4 move downwards, maintain the state of Fig. 4.

Be installed in the example of pars intermedia below in conjunction with Fig. 5 explanation.In example that pars intermedia is installed and previous embodiment, be installed in top example, be that the difference of structure shown in Figure 1 is, the patchhole of locking bar shown in Figure 29 need not be set, so the illustrated cross section of formation is for roughly on the actuator

The actuator 10 of shape as for other structures, also will form Shape hole or groove 4, start plate 5, action shaft 6, fixed axis 7, spring 8 and previous embodiments assembling are with the performance said function.

The present invention adopts said structure, so can obtain following effect.

(1) locking latch component need not be set, be difficult for damaging.

(2), also can adapt to all commodity by changing spring strength even the weight of the jam plate that moves up and down changes because of different commodity.

(3) distance (size) about moving up and down is by changing The overall dimensions of shape hole or groove can adapt to all commodity.
