AI Technical Summary
Existing holding trays for hand-held fire extinguishers often fail to securely enclose the container up to its midpoint, leading to wobbling and potential damage due to imperfect dimensions, and cannot accommodate different models effectively.
A holding tray design with retaining tongues that exert a force on the container, ensuring secure positioning by pressing it firmly onto the tray base, using a locking mechanism that overcomes dimensional mismatches and allows easy removal.
The tray securely holds fire extinguishers without wobbling, accommodating various models, and ensures easy access, even with slight dimension discrepancies, enhancing stability and usability.

Abstract
Description
[0001] The invention relates to a holding tray according to the preamble of claim 1. This is described in DE102010015459 B4 in that the holding tray is adapted to the circumference of the container of the hand fire extinguisher when the latter is received therein and fastened by a strap described in the prior art.
[0002] If the holding tray is intended to enclose the cylindrical container of a hand-held fire extinguisher up to the container's midpoint, and perhaps even slightly beyond, it is virtually impossible to ensure that the dimensions of the container and the holding tray match perfectly. The container wobbles when placed in the tray, which is accompanied by noise and can also lead to damage.
[0003] Patent application DE 10 2010 015 620 A1 discloses a bracket for hand-held fire extinguishers in motor vehicles, designed to securely and firmly attach the fire extinguisher to a surface, such as a wall or under a seat in the vehicle. The bracket is intended to withstand extreme loads, in particular the high forces and decelerations encountered during vehicle crash tests (up to 200g). The design is engineered to securely fix the fire extinguisher. The bracket is specifically designed for flat, cylindrical, or elliptical hand-held fire extinguishers and allows for space-saving and secure mounting in the vehicle interior.
[0004] Utility model DE 79 32 952 U1 relates to a fastener on a carrying strap for hand-held fire extinguishers, in particular for the secure and easy attachment and tensioning of the carrying strap around the extinguishing agent container. The aim is to improve handling, especially easy tensioning of the carrying strap by means of a pivoting tensioning lever and easy opening of the fastener via a releaseable lock with a button.
[0005] Utility model DE 18 62 667 U discloses a fire extinguisher holder with an elastic spring clip and a releasable wire clip by means of an opening lever, particularly for hand-held fire extinguishers, which ensures a vibration-proof mounting while simultaneously allowing quick removal of the fire extinguisher. The holder is intended for use in motor vehicles or similar applications where both secure fixing and rapid accessibility in the event of a fire are required.
[0006] The object of the invention is to design the holding tray in such a way that it encloses the container up to near or up to the middle plane of the container or even slightly beyond, but still ensures a secure, movement-free position of the container of the hand fire extinguisher in the holding tray when the hand fire extinguisher is strapped into it.
[0007] The solution is defined as claim 1 with an advantageous embodiment according to claim 2. In this embodiment, the retaining tongues according to the invention assist in removing the hand-held fire extinguisher, as they exert a force on the container directed towards the opening of the retaining tray.
[0008] The invention is described below with reference to the figure, which shows a radial section through the retaining shell; on the left side of the figure, the section lies in a radial plane located within the retaining tongue. On the right half of the figure, the section lies in a radial plane located in front of the retaining tongue.
[0009] The circumference of container 1 is only indicated. The retaining tray 2 extends with its side walls 2.1 and 2.2 beyond the central plane 3 of the container and, together with the edges of the side walls, forms the insertion opening of the retaining tray. A retaining strap 5.1 (left) and 5.2 (right) is hinged to the longitudinal edges of the side walls 2.1 and 2.2 at the joints 4.1 and 4.2. The two retaining straps are connected at their free ends to the interacting parts of a locking clamp. This clamp is described in the prior art. It connects the two retaining straps 5.1 and 5.2 to each other and tensions them in such a way that the container of the hand-held fire extinguisher is pressed firmly onto the base of the retaining tray.
[0010] The opposing force exerted on the container of the hand-held fire extinguisher by two opposing retaining tongues 6.1, 6.2 must be overcome, such that the hand-held fire extinguisher is pushed out of the opening of the retaining tray. This opposing force must also be overcome by the locking clip.
[0011] The retaining tongues 6.1, 6.2 are designed as levers clamped at one end. They are formed by cutting out three sides of the circumferential wall, while their clamping ends remain connected to the circumferential wall. Along each side of the circumferential wall, two or three such retaining tongues are clamped with their clamping ends just below the median plane of the circular cylinder that the retaining shell circumscribes with its inner circumference. Two such retaining tongues 6.1, 6.2 are located opposite each other on a radial plane, although this is not necessary.
[0012] When the container is inserted, the retaining tabs exert a force against the force exerted by the locking clip. The locking clip overcomes this force and presses the container down to the bottom of the retaining tray. The opposing retaining tabs 6.1 and 6.2 then exert a lateral force on the container of the hand-held fire extinguisher. This ensures that the container is held securely and without wobbling, even if its dimensions do not exactly match those of the retaining tray. Firstly, such precise tolerances cannot be expected over the entire lifespan of such a retaining tray, as hand-held fire extinguisher models are sometimes modified for various reasons. Secondly, it is also possible to store hand-held fire extinguishers of different origins as spare parts in an existing retaining tray without wobbling.
