Abstract

A device in shelf stands with several shelves (3) with sloping storage trays (4) which are extendable on a holder arm (5) in order to facilitate replenishing and removing goods stored in the trays. The trays (4) are secured in the retracted position by means of a locking device which is operated from the front side of the trays. The locking device comprises a leaf-shaped locking hook (9,15) which when the tray is extended moves in a channel (10,16) arranged in the upper or under side of the tray. At the end facing the back side of the tray the locking hook is connected to a pivot (13,13a) in the holder (5) and at the other end, when the tray (4) is retracted to its position of application extends from the channel (10,16) with a hook-shaped part (14,19) which is arranged to cooperate with a locking plate (12,18) on the front edge of the tray which engages the hook-shaped part (14,19) of the locking hook (9,15).

Description

Locking device in the shelf stands

Technical field

The present invention relates to the device in the shelf stands, shelf stands has some shelves, these shelves have the inclination memory disc, these inclination memory discs or shelf can extend on the retainer arm, so that replenish and remove the goods that is stored in these dishes, by means of front side operating locking means these dishes are fixed on retracted position thus from these dishes.

Background technology

Disclose this shelf stands in Swedish patent No.449293, wherein from extended extensible shelf of some circular sectors of arm upper support of newel or dish, made the circular shelf of these dish types, this circular shelf is arranged to slightly downward-sloping.These dishes are provided with locking device, and this locking device is locked in retracted position and extended position respectively with these dishes.

Summary of the invention

Therefore wish the not obvious height that to store goods on the shelf that surpasses of distance between these shelves, make that the total height of shelf stands is as far as possible little.Problem is to realize locking device, and this locking device does not take the distance between the shelf, but still can be from the front side operational lock device of these dishes.

The objective of the invention is to realize solving the locking device of described problem, and realize this purpose by the locking device of the feature defined in the realization claims according to the present invention.

The specific embodiment

Shelf stands shown in Figure 1 comprises the newel 1 that is supported by base or pin 2.The shelf 3 that these newel 1 some layerings of supporting are provided with, these shelves 3 can rotate around post 1 individually.

Each shelf is by the fan-shaped shelf portion of some primary circles that can extend on arm 5 or coil 4 and constitute, and these arms 5 extend from retainer 6, and this retainer 6 is arranged on the newel 1 in rotating mode.These dishes are provided with cannula-like part 7, and this cannula-like part 7 is placed on the corresponding arm 5 in telescopic mode, and is bearing on the support wheel 8 (Fig. 4), make dish 4 moving between retracted position and the extended position fully.These arms 5 are downward-sloping, make that the goods on the shelf needn't extend this dish to lower slider against the front side.If, then must can extend this dish if this inclination does not take place or refill goods on the shelf, see Fig. 2, dish 4 is extended shown in it.For example limit these extension of dish 4 in support, mobile (not shown) in the slit of this screw in the sleeve pipe 7 of dish 4 in mode known per se by the limit screw that is arranged on the arm 5.

Because these coil inclination, so these dishes must be fixed on retracted position from the outward flange operating locking means of coiling easily.The rear edge facing to retainer 6 at dish has been arranged known fixture, and operates this fixture by means of the uncovered arm that is arranged in dish 4 belows, and this arm is influential to the space between these dishes.

Alternatively, according to the present invention, elongated leaf lock arm or hook 9 are provided, this lock arm or hook 9 are shown in Fig. 3-5, and this lock arm or hook 9 extend in the raceway groove 10 that is formed at dish 4 upsides, and this raceway groove is connected on the sleeve pipe 7, and forms by inverted U-shaped 11, basic centre in dish, this inverted U-shaped 11 is fastened on the upper surface that for example is welded to dish 4 bottoms.Raceway groove 10 is just wide to making than the thickness of stay hook 9: this stay hook 9 is owing to can move freely in this raceway groove to the very little play of the side of raceway groove 10, and bigger in vertical direction play allows lock hook 9 to enter and break away from coil 4 front sides on the engaging of lockplate 12.For this reason, lock hook 9 is supported on the pivot 13 at its inner place, makes that partly catching plate 12 also will coil 4 lock hooks when being locked in retracted position when the counter of lock hook 9 can upwards swing, and this pivot 13 is fastened on the inner of arm 5.Make the outer end of lock hook 9 circular for this reason, make lock hook 9 when its crash panel 12, be raised also and descend on plate 12 with otch 14 owing to gravity.

In embodiment according to Fig. 6-8, stay hook 15 is arranged to side below dish 4 flatly in raceway groove 16, on having, this stay hook 15 turns over part 15a, should on turn over part and be supported on the corresponding pivot 13a of pivot on the arm 5 and Fig. 4 13, this raceway groove 16 is formed by U-shaped plate 17, here, this U-shaped plate 17 also in dish basic centre be fastened to for example be welded to described below on the side.Hook 15 in this case, only between the side of stay hook 15 and raceway groove 16, has very little play, because can only move freely when dish 4 extends on the longitudinal direction of raceway groove 16.When withdrawal dish, therefore will coil 4 is locked in retracted position to be fastened on the locking bolt 20 at place, front side of dish, and this locking bolt 20 is the otch 19 in the engage hook 15 by means of flip portion 18.This locking bolt 20 is made by elastomeric material, and biased against shown in latched position, still, when dish 4 will extend, this locking bolt 20 can break away from and the engaging of the otch 19 of hook 15 by motion arm 21.

It is evident that from above: have the embodiment that is maintained at the leaf lock hook 9,15 that is arranged in dish 4 tops or following

narrow raceway groove

10,16 and do not rely on the height of dish, but can make the distance between the shelf 3 adapt to the height that to store goods on the shelf fully.

When in order to replenish goods extension to be coiled 4, lock hook 9 is from mentioning with the (see figure 4) state that engages of plate 12, and perhaps locking bolt 20 stops the (see figure 7) that engages with otch 19, makes dish unclamp.When dish 4 when withdrawing once more, lock hook 9 and 15 enters respectively and the engaging of lockplate 12 and locking bolt 20, and makes these dishes be locked in their normal use position.Owing to be arranged on these locking devices at the leading edge place of these dishes, operation will simple and safety.

Obviously, the present invention is not limited to these disclosed embodiment, but except shown in can change the present invention in order to make these locking devices adapt to shelf stands and dish those embodiment.
