TH8633A - A handheld device for dispensing adhesive film material from a backing strip onto the desired surface. - Google Patents

Abstract

A handheld dispensing device for dispensing adhesive film from a backing strip onto a desired surface consists of a cartridge housing containing a delivery and return reel for the backing strip, mounted on a rotating sleeve. At least one reel is equipped with a reverse rotation lock. The two rotating sleeves are connected by a gear system with a sliding clutch component operating in the rotational direction. The adhesive film side of the backing strip is pressed against the desired surface, and after passing through the dispensing component, it rewinds into the cartridge housing and onto the return reel. This invention aims to find a way to improve this type of handheld dispensing device by reducing the number of components and simplifying its manufacturing process. The above-mentioned thing is achieved by the way in which the gear system (18, 19) is integrated into the rotating housing (8, 9) and the sliding clutch assembly is part of the gear system (18, 19).

Claims (4)

1. A handheld device for dispensing adhesive film from a backing strip to the desired surface, consisting of a housing containing a delivery reel and a return reel for the backing strip, mounted on a rotating sleeve provided for rotation on the housing. A locking mechanism is incorporated into at least one of the reels. The two rotating sleeves are connected by a gear system consisting of a sliding clutch assembly operating in the direction of the rotating shaft. The backing strip, which can be released from the delivery reel, is guided to straddle the delivery element, which extends from the housing and is designed to press the backing strip so that its adhesive film side is pressed against the desired surface. After passing through the delivery element, it is rolled back into the housing to wrap around the return reel. The gear system (18, 19) and the sliding clutch assembly are part of the gear system (18, 19). 2. A handheld device as claimed in Reputation 1, which is such that the teeth (20) of the rotating sleeve (8) for the delivery reel (23) are formed into a thin constriction (28) in the area between the gear teeth (29) and the gear teeth (30), and also such that at the gear teeth, the gear teeth (20, 21) of the two rotating sleeves (8, 9) are beveled (26, 27) in a plane perpendicular to the gear teeth such that in the case of a difference in speed, the gear teeth (20) of the rotating sleeve (8) for the delivery reel (23) can slide over the gear teeth (21) of the rotating sleeve (8) for the receiving reel (24). 3. A handheld device of the type claimed in claims 1 or 3, which has a type of anti-reverse lock (32), shall be assembled together with the gear system (18) of the rotating sleeve (8) for the delivery reel (23). 4. The handheld device as claimed in claims 2 or 3, which has a beveled gear (20) underneath, has a reverse rotation lock in the form of a beveled housing piece (32) so that the gears (20) of the rotating sleeve (8) can slide over the housing piece (32) only in the direction of rotation.
