DE3214701A1 - HEIGHT-ADJUSTABLE WALL SHELF - Google Patents

Abstract

The height adjustable shelf rack comprises two rails (3) intended to be secured to a wall (1) and height adjustable brackets (4) along the rails to support the shelves (5). The rack lends itself to a wooden construction. The rails (3) are provided with guiding grooves (6) having a T-shaped cross-section of which the cross bar is provided with rounded corners. The shape of said grooves correspond to the guiding profile (7) of the brackets (4). Thereby an appropriate distribution of forces is obtained and the risk of breaking or splitting wood is attenuated. Furthermore, means enable a concealed height locking of the brackets.

Height adjustable. Wall shelf

The invention relates to a height-adjustable wall shelf with two rails that can be attached to a wall and therein height-adjustable brackets for supporting shelves, with provided in the rails, themselves on the wall side widening guide grooves and guide profiles adapted to the shape of the guide grooves the consoles.

In a known such wall shelf, the guide grooves are dovetail-shaped. In the event of a load of the shelves, a large part of the forces acting on the guide profiles on the dovetail Transferred trained guide grooves, in particular the opposite, widening towards the rear Web of the dovetail guide groove are heavily loaded. This is particularly disadvantageous when the wall shelf is made of wood, as this material often cannot withstand the loads that occur and tears out or splintered.

To remedy this disadvantage, the invention is primarily based on the object of a height-adjustable To create wall shelf of the type mentioned, in which

the power distribution is chosen more favorably.

To achieve this object, the invention provides that the guide groove and the guide profiles have a "T" profile with rounded corners on the crosspiece of the "T". Since in this configuration neither the Guide grooves nor the guide profiles have edges that converge at an acute angle, no pressure peaks occur and the risk of tearing or splintering is avoided or greatly reduced.

The brackets of the known wall shelf are locked in that holes are drilled in the guide groove at intervals are provided, and the consoles have a through hole through which pins can be pushed through from the outside are that the respective end of the pin engages in one of the holes. The disadvantage here is that the front, mostly with a button front end protrudes over the console, which disturbs the overall visual impression. In addition, there is a risk that the pin will be pulled out unintentionally, with the result that the console slips off.

Another sub-object of the invention is to create an improved console lock. For this, in Bores in the bottom of the guide groove insertable pins are provided, the length of which is at most the depth of the guide grooves plus the drill hole depth. The lower end of the console has one opposite the lower end of the guide profiles above area. In other words, the console is notched at the bottom provided with which it can be pushed over the pin inserted into one of the drill holes. Achieved this way an invisible console lock, and accidental pulling out of the pen is not possible.

Further features and advantages of the invention will be based on

of the embodiment shown in the drawing. Show it:

Fig «1 is a central longitudinal section through one on a wall attached rail, a console (for better clarity in side view) and a

laid shelf;

FIG. 2 shows a section along the line IX-II in FIG. 1; FIG. 3 shows a section along the line III-III in FIG. 1;

4 shows a section through an area outside of the areas covered by the guide profiles of the consoles

Cover strip that can be inserted into the guide grooves.

The height-adjustable wall shelf according to the invention has at least two rails 3, which can be attached to a wall 1 by means of screws 2, for the height-adjustable attachment of consoles 4, on which shelves 5 can be placed. The rails 3 are each provided with a guide groove 6 continuously formed in the longitudinal direction, which has a "T ^M -shaped profile with rounded corners on the transverse web of the" T. A guide profile 7 is attached to each of the brackets 4, the outer profile of which corresponds to the Inner profile of the guide grooves, so that the consoles 4 can be pushed into the guide grooves 6. To lock the consoles 4 at a certain height, bores 8 are provided in the bottom of the guide grooves into which pins 9 can be inserted Depth of the guide grooves 6 plus the drill hole depth of the bores 8. This ensures that a pin 9 in the inserted state does not protrude over the front edge of the rail 3. The lower end 10 of the brackets 4 protrudes downward over the lower end 11 of the guide profiles, so that the consoles 4 can be pushed from above onto the respective pin and with the lower end of the guide profile against the pin

gene, while the lower end 10 of the console protrudes further over the pin 9 downwards. Achieved this way you have an invisible lock and prevent unintentional pulling out of the pen. The area of the guide groove not covered by the guide profile 7 of the consoles 4 6 can be covered by inserting cover strips 12, the profile of which corresponds to that of the guide profiles 7 will. The cover strips 12 reach under the consoles, whereby clean transitions are achieved.
