Description

The utility model relates to a wooden handle with an internal metal or plastic fastener, intended mainly for opening and closing windows and doors of buildings.

Currently, various types of handles are known for opening and closing windows and doors. Some of them consist of an internal rigid core, for example, metal in the form of a handle, provided with a shell of artificial or plastic mass or less hard metal or a combination thereof. So, for example, from CH-627223 and DE 10101245 known handles consisting of a solid core of fire-resistant material, which are provided with a shell of another material. The free end of the core, turned to the key, is provided with an opening for the tetrahedron, with the help of which the lock tongue is controlled.

Handles, the surface of which is not made of wood, look when they are used on wooden windows or doors unaesthetically and are cold. Touching the hand during manipulation with them also causes unpleasant sensations, one of which is, for example, cold. This is further enhanced by the fact that, especially with metal pens, they have an unpleasant odor that sticks to their hands.

Handles with wooden lining are also known. So, for example, from FR 2734302 a handle is known consisting of a metal neck, provided at one end adjacent to the key,

the connection point for the tetrahedron, and on the opposite side with a direct rod mount. An oblong wooden handle, machined from one piece of wood and axially fixed with a screw, is worn on the rod mount with its axial bore. A handle is known from DD 217835, in which a cylindrical turned part for holding is provided with a blind axial bore for the connecting reinforcement screw and a recess perpendicular to it, in which one end of the metal neck of the handle is placed. The connecting reinforcing screw of the handle is screwed with its end into the wall of the metal neck located in the above perpendicular recess in the wooden part of the handle intended for holding.

The disadvantages of such handles, which are suitable from the point of view of strength, is that only part of the handle for holding is sheathed with wood, and the metal neck has a cold effect. At the same time, the wooden part for holding may have, due to the direct fastening on which it is worn, and the technology of its processing only a cylindrical shape, which does not meet modern aesthetic trends of rounded shapes of handles made by metal casting.

From DE 2839420 a handle is known having both a holding and a neck made of wood. The neck of the handle is made of a wooden sleeve in the form of a cylinder or a truncated cone, and a fastening in the form of a sleeve, in which the connecting tetrahedron is placed, is firmly inserted into its blind axial bore. The holding part or handle is made of one unreinforced piece of wood, and with the neck part of the handle

connected by a wooden axial spike rigidly planted in a transverse bore, passing both a wooden sleeve and a neck mount in the form of a sleeve.

The disadvantages of such solutions are the simple, unaesthetic form of the handle, consisting essentially of two elongated cylindrical parts mutually connected at right angles, namely: the holding part and the neck part. Such wooden bushings, which are equipped with only direct rigid fastening only after their processing or molding, cannot be processed and given to them a shape significantly different from direct fastening, because keep the minimum wall thickness of the wooden sleeve. In addition, it is necessary to block the holes of the bore or seal them tightly.

Finally, the handle and the key are known according to the Czech utility model No. 5509, where the handle is made of layers of wooden plywood, mutually glued and firmly pressed, the plywood on the handle being located in the direction of the handle holding part, and its surface perpendicular to the imaginary plane passing through the curved axis of the handle . To connect the handle with the door lock at the end of the handle adjacent to the key, a metal brass collar is made, which is firmly connected to the handle.

The disadvantage of this solution is mainly the difficulty in their manufacture, as well as the non-compactness and inhomogeneity of the handle surface - in comparison with a clean wood surface, up to 39 layers of glue account for 2-3 cm of plywood surface. Another disadvantage of this solution is that the natural structure and pattern are lost.

wood on the surface of the handle. Therefore, such a pen did not find practical application.

The objective of the utility model is to create such a wooden handle with internal fastening, intended mainly for windows and doors of buildings, which eliminates the above disadvantages.

This is achieved by the fact that in a wooden handle with internal fastening, intended mainly for windows and doors of buildings, containing a holding part, which is essentially parallel to the sash of a window or door and with which a neck part adjacent to the lock of the door or window means is connected, and the inner recess of the cervical part of the wooden sleeve secured the cervical section of the mount, which goes into the holding section of the mount and is in hard connection with the wooden lining of the mount formed by a tree a separate sleeve, divided by a plane of the connector into the first part and the second part, which are interconnected by their adjacent surfaces, the plane of the connector of the wooden sleeve is essentially parallel to the plane that is the middle axis of the mount, and in the adjacent surface of at least the first or second part of the wooden sleeve made a groove, the shape of which is essentially negative in relation to the fastened part of the fastening firmly fixed in it, and attach the second or first part of the wooden sleeve complementary to its adjacent surface Lena to the adjacent surface of the first or second part.

This design allows you to make a handle with a wooden surface of both the holding and neck parts corresponding to

all bending and torsional strength requirements. In this case, the mount does not consist of two straight sections, but is formed in accordance with the required final shape of the handle. Thanks to the processing of an already reinforced wooden bush, it is possible to use high-precision machining and preferred handle shapes with both ergonomic and aesthetic points of view using conventional cutting and abrasive woodworking tools.

For the handles from which the regulating tetrahedron protrudes, it may be appropriate if the cervical attachment portion and the holding attachment portion are made together of one piece of material. This will make it possible to perform both monosyllabic molding of the fastener according to the required shape of the handle, and to perform the transition of the fastener to the protruding tetrahedron.

For handles having a cavity in the end of the cervical portion of the attachment in which the regulating tetrahedron is located, it may be advisable if the attachment is made of two or more mutually connected parts.

This will allow both simple molding of the fastener in accordance with the desired shape of the handle, and a simple implementation of the cavity for the tetrahedron in the cervical portion of the mount.

It is advisable if the plane of the connector of the wooden sleeve is identical to the plane, which is the middle axis of the mount.

This will allow the implementation of the handle, a wooden sleeve which will best meet the requirements for the handle in terms of strength.

Further, it is advisable if in the walls of the mounting grooves

pocket-like recesses are made.

These recesses, if necessary, allow you to accommodate the excess glue with which parts of the sleeve are glued together or with fastening.

It is also advisable if the pattern of annual circles of the wooden sleeve is located essentially parallel to the holding portion of the mount. This design provides sufficient bending strength of the holding part and its end part, which then does not require fastening.

As shown in the drawings, the handle is made of a fastener 2, around which there is a wooden sleeve 1. The wooden sleeve 1 consists of two longitudinal, mutually complementary parts, namely, from the lower, first part 11 and the upper, second part 12. The fastener 2 is molded approximately in the direction of the imaginary middle axis of the final shape of the wooden handle, the middle axis O of the fastener 2, which is reasonably identical with the imaginary middle axis of the handle, is located in the plane ψ. The plane ψ is the plane of symmetry of the fastening 2, and basically it is perpendicular to the sash of a window or door not shown. The fastener 2 comprises a neck portion 21 of the fastener 2, which is facing a door or window device not shown, and when opened with a handle, it is mainly subjected to a twisting load. The holding portion 22 of the fastener 2, which is essentially parallel to the sash of the window or door, and when opened by the handle, is exposed mainly to bending load. The cervical section 21 of the fastening 2 at its free end passes either directly to the tetrahedron 23 (see Fig. 8), which the handle controls the unimaged lock, or the cervical section 21 of the fastening 2 is provided with a cavity 25 (see Fig. 1 and Fig. 6) for stationary support of the tetrahedron 23, the opposite door handle or plug-in tetrahedron for window handles. The cavity 25 for the tetrahedron 23 can be made directly in

the thickened end part of the fastener 2 or can be made in the sleeve 24, which is attached to the fastener 2, for example, by a weld seam 27. For a better fit, the rotation of the handle in a door or window device or in a key-holder was created at the transition of the fastening 2 to a square 23 or the end of the sleeve 24 for the tetrahedron landing flange 26.

The mount 2 is made of either metal or plastic, mainly by injection molding technology. This technology allows casting of the fastener 2, corresponding to the characteristic of the imaginary middle axis of the final shape of the wooden handle.

The wooden sleeve 1 around the mount 2 or the sheathing of the mount 2 with a tree is made as follows:

Semi-finished products for one wooden sleeve 1 are two oblong wooden blocks with the same size bases and with annual circles essentially parallel to the long side of the bars. Mutually applied bases are treated so as to form abutting abutment surfaces 111, 121, which, after the attachment 2 is placed, both bars will be joined with glue. The adjacent surfaces 111, 121 form the plane of the connector m of the resulting wooden sleeve 1. In the abutment surface 111, 121 of each beam, for example, by milling, the fixing groove 141, 142. Its shape will be negative with respect to the shape of the part of the fastening 2, which then inserted and will be wider than it by the thickness of a thin layer of glue. On the adjacent surfaces 111, 121, glue is applied, after which, with its mounting grooves 141, 142, they are mounted on the mount 2 and

both halves of the beam are compressed, for example, by a press. Possible excess glue between the glued abutment surfaces 111, 121 is forced out, firstly, into the pocket-like recesses 15 designed for this purpose, created in the lateral surfaces of the mounting grooves 141, 142, and, secondly, outward past the glued parts 11, 12. After gluing the first part 11 and the second part 12 of the wooden sleeve 1, the bonded prefabricated wooden handle is processed on woodworking machines in the usual way to the desired shape of the handle. Then carry out the final surface treatment by staining or varnishing. Due to the fact that the semi-finished product of the wooden sleeve 1 is reinforced with a fastener 2 before processing, it is stronger and more stable when humidity changes and it can be processed with greater accuracy.

When using the fastener 2 with a rectangular or square cross-section, the plane of the connector t of the wooden sleeve 1 can be guided to one wall of the fastener 2, as shown in Figs. 9-11.

In this case, it is not necessary to make the mounting grooves 141, 142 in the adjacent surfaces of both parts 11, 12 of the wooden sleeve 1, but only in one of the adjacent surfaces 111, and the second adjacent surface 121 to be glued to the first adjacent surface 111 and to the butt wall of the mount 2.

In the scope of the utility model, obviously, it is possible to divide the first part 11 or the second part 12 of the sleeve 1 into the following mutually complementary parts.
