Embodiment Construction

[0013] The invention can be better understood with reference to the accompanying drawings (an exploded view of the device) and with the aid of the following description of a preferred form of the device assembly of the invention.

[0014] The device that will now be described is a sealing device for driving a closure screw 1 (in the form of a nail) into the mounting material. The device comprises: a handle 3 in the casing 2, a slide 4 mounted slidingly in the handle 3, a notch 5 with a firing pin in the rear of the slide, a closed screw guide in front of the slide 7, which has a loader 8 comprising a plurality of closure screws 1 . Each closing screw 1 is advanced by the piston 9, during the positioning of the device before firing, by covering the chamber 11 at the moment of the rebound of the sleeve 4, before the explosive 10 which has previously entered the chamber 11 located at the rear of the sleeve 4 Under the action of the combustion gases, the piston 9 moves in the sle...

Abstract

The device is intended to propel a fastening element (1) under the action of combustion gas from an explosive charge contained in a cartridge (10) mounted on a cartridge holder (13) received in a gun holder (3) and intended to be entered into a combustion chamber (11) situated at the rear of the cannon (4) slidably fitted in the gun holder (3). Also foreseen is an opening lever (19-25) designed to, after firing, draw the cannon (4) forward in the gun holder (3), bring it away from the cartridge holder (13) and thus open the device .

Description

[0001] Related references [0002] This application is based on, and claims priority from, French application serial number 0506551 filed on June 28, 2005, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present invention relates to a fastening device for advancing a fastener under the action of combustion gases originating from powder contained in a bullet mounted in a cartridge holder in the handle and pushing the bullet into a removable The chamber is slidably mounted to the rear of the slide in the handle. Background technique [0004] After one shot and before another, it is first necessary to open the device so that the slide is moved away from the magazine by the forward slide of the slide. Due to the expansion of the cartridge case, it sometimes happened that the deliberately fired cartridge case became lodged in the chamber, making it difficult to move the slide forward. [0005] It also sometimes happens that the o...
