Description

People constantly have to carry some kind of loads, weights, hand luggage. The most common burden for urban residents today is supermarket bags, bottles, cans, nets, buckets, etc. Although such a container is adapted in terms of weight and volume to a person's capabilities, nevertheless, narrow handles often cause considerable discomfort when holding the weight for a long time, and when there are a lot of packages, even shifting them from one hand to another requires tension, as does the search for all the handles of the packages. for example, in the dark in the trunk of a car. Also, in cold weather, wearing gloves, and even more so mittens, it is very inconvenient to look for and touch the bag handles. Research on existing carrying handles has shown that not all of these needs have been optimally addressed. Some of the prior art devices are designed to reinforce and harden prior art structures to carry more weight. We approached the problem from the point of view of ergonomics, and although the invention also allows you to carry large weights, it is primarily aimed at ease of use, including for the elderly, who do not need to carry too much weight, while the structure can also withstand high loads ... Our invention is designed to solve the above problems by combining several useful properties and functions in one object: increasing the surface area of contact between the palm and the load, ensuring the most ergonomic angle of inclination of the handle relative to the center of gravity of the load with the possibility of adjusting it, easy reliable fixation of bag handles, bottles, hinges, straps and so on. inside the handle, the ability to attach the handle together with the load to some external support, and, finally, the ability to carry the load with one hand and at the same time use the flashlight built into the handle. The novelty and originality of the invention lies in the fact that it combines several functional elements, which in the proposed configuration creates a new device that opens a new level of comfort in using handles for carrying weights and expands their capabilities.

A number of analogs are known from the prior art - devices for carrying carry-on luggage, similar in configuration. Since the main function of the claimed utility model is convenience in carrying carry-on luggage, we examined groups of analogs with both carabiners and without carabiners. According to the design features, several types of analogs can be distinguished.

1. To the first type of analogs, we include closed-shaped handles with a hole for the palm, having one or more hook-shaped elements for hanging in the outer part [1-5]. The disadvantage in using these models is that each item has to be suspended and removed carefully enough, while fine motor skills are involved, which is inconvenient when working with heavy things. The distribution of weight in relation to the ergonomics of the hand is also not taken into account.

If there is only 1 hook, as in the device US 2003110593 A1, (2003), the disadvantage is that this device has an inconvenient lock, which makes it difficult to release the luggage handles. There is also no carabiner for quick fixing of the entire handle to the external non-hook support.

In the case of EA 017488 B1 (2012), where the hook is large enough and has a swivel lock, the disadvantage is: a smooth surface for the straps, the absence of a carabiner for quickly fixing the entire handle together with the bags to the external non-hook-shaped support.

Also known patent RU 109381 U1 (2011), describing a device with a closed handle, having hook-shaped elements in the form of carabiners, attached symmetrically to the lower part of the handle, or a device in the form of a carabiner, the latch of which closes the housing bracket, is spring-loaded and equipped with a control button. The disadvantage of the product is the lack of ergonomic adaptation of the product, namely, the anatomical structure of the hand and the desired distribution of the weight of the carried items relative to the handle are not taken into account according to the ergonomics of the hand.

The device described in patent RU109381U1 (option 2) (2011) can be attributed to the third type, see below.

2. To the second type of analogs, we refer products of symmetrical shape with a handle having hook-shaped elements on the sides. The disadvantage is that in the case of uneven weight distribution, the handle will tilt, increasing the load on the hand and wrist, and the bags will sway when walking. Also, the desired distribution of the weight of the carried items was not taken into account according to the ergonomics of the hand [6-8].

Among such analogs, patent US 2017065068 A1 (2017) stands out, which describes a device with a closed handle and hook-shaped elements on the sides and slots for bag handles extending from the sides to the center of the handle. The disadvantage is that the design does not have a retainer that securely fixes the straps of the bags inside the handle or fixes the handle itself to an external non-hook-like attachment.

3. To the third type of analogs, we include devices that have an open or split handle design, which allows the bag handles to be brought inside [9-16]. The disadvantage of most designs is the possibility of amplitude sliding of the handles inside the handle (for example, see RU 109381 U1 (2011) option 2) and the lack of ergonomic adaptation of the product: the design does not provide the possibility of a controlled distribution of the weight of the carried items relative to the handle and the wrist. It also lacks a carabiner that fixes the handle itself to an external non-hook-shaped mount.

4. To the fourth type of analogs, we include devices that have an open or detachable design of the handle, which allows the handles of the carried baggage to be brought inside with the arrangement of hook elements inside the handle, which prevent sliding and amplitude movement of the handles of the carried baggage relative to the center [17-24]. Among the disadvantages is the lack of a carabiner that fixes the handle itself to an external non-hook-shaped mount.

In the product GB 432477 A (1935), the design prevents the handles of the carried luggage from sliding inside, but there is no ergonomic adaptation of the product in terms of weight distribution relative to the hand.

In this group, an analogue of RU 91267 U1 (2010) can be distinguished, which describes a closed handle having T-shaped hooks facing the center on the inner side of the lower part. The disadvantage of the product is the lack of ergonomic adaptation of the product, namely, the anatomical structure of the hand is not taken into account and the provision of an ergonomically correct distribution of the weight of the carried items relative to the hand. Also, the design will not allow you to fix hand luggage with an inflexible handle on the handle, since it involves putting the handles on the side. Also, the design does not have a retainer that securely secures the straps of the packages inside the handle or fixes the handle itself to an external non-hook-shaped mount.

An analogue of FR 2707598 A1 (1995), which has an open handle and one hook-shaped outer element, also stands out separately. The disadvantage is that this device does not have a retainer, and the straps or bag handles can fall out of the hook in case of a decrease in the load. Also, the design does not have an additional hook-carabiner that allows you to attach the handle itself to an external non-hook-shaped mount.

Separately, there are several analogs without a carbine, similar in morphology.

Thus, patent BRPI0606085 A (2008) describes a device for carrying carry-on luggage in the form of an open handle with an anatomical handle and a retainer, having small dividers for the straps and handles of the carried luggage on the lower part. The disadvantage is that the design is not optimized for the ergonomically correct distribution of the weight of the carried items relative to the hand. Also, the design does not have an additional hook-carabiner, which allows you to conveniently attach or hang the handle itself along with the load to an external non-hook-shaped mount.

Patent FR 2754243 A1 (1998) describes a carry-on carry-on device in the form of an open handle with an anatomical handle and a retainer, having small dividers on the bottom for the straps and handles of the carry-on luggage. The disadvantage is the relative complexity of manufacturing; also, the design does not have an additional hook-carabiner, which allows you to conveniently attach or hang the handle itself together with the fixed weight to an external non-hook-like attachment.

Patent FR 2845259 A1 (2004) describes a carry-on carry-on device in the form of an open handle with an anatomical handle and a retainer, having small dividers on the bottom for the straps and handles of the carry-on luggage. The design does not have an additional hook-carabiner, which allows you to conveniently attach or hang the handle itself together with the load to an external non-hook-like attachment. It is also a disadvantage that when using the device, it is necessary to open and close the latch every time, and with an open latch, the suitability of the device with a flexible handle is questionable.

Patent CA 2548241 A1 (2007) describes a carry-on carry-on device in the form of an open handle with an anatomical grip, having small dividers on the bottom for the straps and handles of the carry-on bag. The disadvantage is the asymmetrical handle, as well as not clearly defined dividers for the straps, as a result of which the design is not optimized for the possibility of an ergonomically correct distribution of the weight of the carried items relative to the wrist, and the design does not have an additional carabiner hook, which allows you to conveniently attach or hang the handle itself together with the fixed weight to an external non-hook mount.

The device from the patent CN 108835851 A (2018) can be considered a similar prototype in terms of the ergonomic scheme: a device for carrying hand luggage in the form of an open carabiner with an anatomical handle and a retainer, which has small notches on the lower inner part for the straps and handles of the carried configuration assuming an ergonomic weight distribution around the wrist. The main disadvantage of this prototype is the asymmetry of the inner part of the handle, which requires the user to take the device only with one specific side and can cause inconvenience if the structure is taken with the wrong end forward, since the optimal ergonomic distribution of the weight of the carried loads relative to the wrist will be violated. Also, the design does not have an additional hook-carabiner, which allows you to conveniently fix or hang the handle itself together with the load to an external non-hook-shaped mount.

The next group of analyzed analogs is characterized by the fact that the design is based on a carabiner with an elastic rotary lock, and its dimensions allow it to be used as a carrying device, or a carabiner with an added handle.

So, patents belong to the fifth type [25-27]. The main disadvantage of the devices described in these patents and applications is that the pivot element locking the carabiner becomes part of the support surface for hanging carry-on luggage, and this creates great difficulties and inconveniences, for example, when part of the bags needs to be removed from the carabiner. Also, the bottom surface is smooth, the absence of hooks-restraints also creates a prerequisite for the sliding of the suspended packages.

In patent application US 2007062013 A1 (2013), one of the variants of the carabiner with a handle has an additional carabiner in its design. This option can be taken as a prototype of the product we offer. However, the disadvantages are the absence of hook-shaped stops inside the carabiner, and a pivoting element in the lower part, which creates inconvenience in use.

Thus, we can say that the device proposed in this application, which increases the ergonomic properties and convenience of the possibilities of carrying, grouping, fixing carry-on luggage, hanging the device together with carry-on luggage, has close analogs among the handles for carrying and carabiners known from the prior art: patent CN 108835851 A and a device from patent application US 2007062013 A1.

With regard to combining the function of a flashlight and a carabiner, prototypes can be considered devices from US 2007013530 A1 (2007) patents, where various complementary elements can be added to the carabiner, US 5270909 A (1992), where the flashlight handle has a carabiner-style lock, USD441473S (2001) where the body of the flashlight has a carabiner on the side. The closest analogue of a device for combining a flashlight and a carabiner, which could be tried to be used as a handle for carrying, can be considered a device from US Pat. No. 6,715,898 B1, which has a built-in flashlight in the part of the carabiner body opposite to the latch. The main disadvantage is that if you try to use the device as a handle for carrying luggage, then the rotary element that locks the carabiner becomes part of the support surface for hanging carry-on luggage, and this creates great difficulties and inconveniences, for example, when you need to remove part of the packages from the carabiner. Also, a smooth bottom surface, the absence of hooks-restraints creates a prerequisite for the sliding of the suspended packages.

Attempts to combine a lantern and a specially designed handle for the convenience of carrying hand luggage have not been found in the prior art, with the exception of a similar device from US 7487565 B1 (2009), which proposes a multifunctional device for a hunter. Consisting of a pen, a flashlight, a saw, etc. The disadvantage of such a device is that the handle is not hook-shaped, which prevents the straps of bags, bottles, etc. from catching.

So, the technical result of the proposed invention is to improve the ergonomics and convenience of carrying, grouping, fixing carry-on luggage, ensuring that the handle along with the carry-on luggage is suspended on an external support, providing the possibility of attaching a shoulder strap, and, finally, in combining these functions in one device with flashlight, as well as the ability to fully operate the device with one hand.

To achieve the specified technical result, a carabiner handle is proposed for carrying bags, bottles and other carry-on luggage, which is an open Q-shaped configuration in the upper part, containing an ergonomic handle A, having a symmetrical inner surface B and a rotary lock 1 fixed in the upper side its parts above the opening, at least one inclined hook-shaped protrusion 2 located on the lower inner part of the structure and oriented towards its middle, and at least one additional hook-carabiner 4 having a rotatable elastic closing latch 3 located from the outer part of the structure in one plane with the handle A and the lower part of the structure 5, characterized in that the hook-shaped protrusions 2 protruding by at least 20 mm, distributed on the inner surface of the lower part 5 of the structure, have an inclination towards the additional hook-karabiner 4 located on the side outside the structure, which prevents slip la mock of fixed carry-on luggage when hanging the entire structure to any external fastening, rotary latches 1 and 3 in the width on both sides protrude at least 5 mm from the edge of the side plane of the structure, also on at least one side on the upper part of the handle there is a hole 5 for threading the cord, and holes 6 with a pivoting metal arc-shaped bracket 7 threaded through them for connection with a flexible shoulder strap, and in the upper part of the handle above the opening there is a cavity 8, in which batteries 9 and LED 10 fixed in a plastic corset are placed, and the plug the cavity 11 is made of transparent plastic serving as a light-guiding lens; there is also a sliding switch 12 on top, a closing contact 13, pressing it against another contact. The symmetrical inner surface of the handle allows you to comfortably grip the handle with either side: front or back, right or left hand. And the side parts of the handle, bent downward, like a cane, allow partially relieving the load from the fingers and distributing it on the inner back surface of the hand. The main ergonomic scheme is that the carabiner handle assumes its positioning in the hand not parallel to the ground, but at an angle, which significantly reduces the load on the hand and wrist, and makes carrying loads much more comfortable. Hook-shaped protrusions 2, which prevent the strap of carry-on luggage from excessive slipping inside the handle, allow you to arrange unweighted items of carry-on luggage in the most optimal way. Elastic clamps 1 and 3, used to close the main opening of a carabiner-like structure, are made of spring wire protruding at least 5 mm in width from the edge of the side plane of the structure, which makes it convenient to open and close the clamps with one finger of the same hand, which holds the handle with the weight. The clips 1 and 3 have a special zigzag configuration in side view, namely, two bends in opposite directions with an angle of about 140 degrees, which makes it easy to hook and release the clip with a finger. Located under the opening and partially forming it, the lower part of the structure 5 is bent upward and has a thickening 14 at the end in the form of a hook-shaped spout, which allows fixing the pivoting bracket 15 located above the opening as an additional closing element, so that the bracket 15 above the opening can not only be used for fastening the shoulder strap paired with a bracket 7 on the other end of the handle, but also serve as an additional closing lock for the main opening, moving the free end outside the structure around its axis at the attachment point 17 at an angle of up to 270 degrees, and in the closing position creates additional support for the lower part of the structure 5 under load. The elastic metal braces 1,3,7,15 can be pulled out of the holes, so the user can remove the extra braces if, for example, not using the shoulder strap. On one of the hook-shaped protrusions 2, as well as on the external hook 4, there are external recess-stops 16 in order for the clips of the brackets 1 and 3 to reliably block the openings like a carabiner. Cylindrical magnets 19 are inserted into the upper end parts of the handle through the through holes 18, which serve to hold the semicircular brackets pressed against the surface of the handle. On the end part of the structure opposite the lantern, a shaped recess 20 with a protrusion can be made for opening bottle caps or unscrewing nuts of different diameters. The inner surface of the handle B can be made with a slight relief for the fingers. Also, the area of the handle can be treated with a softening material by spraying, wrapping, or a sleeve made of plastic soft and anti-slip material can be put on it. Along the entire perimeter, the main structure has a chamfer on the edges for more delicate contact with the handles of packages, bags, etc.

Tests of prototypes and working models of the invention have shown great reliability and convenience of the carabiner handle for carrying luggage under significant loads. The inventive device can be made in several ways from different materials and using different technologies. The material for the main part of the structure can be either wood or various durable types of plastic. The predominantly planar configuration of the device, its simple and reliable design make it possible to manufacture the main part by milling or laser cutting various sheet materials, from plywood to sheet monolithic polycarbonate or metal. If the main part of the product is made by laser cutting or milling from a solid sheet, then the main structure will be a single monolithic part of the desired profile with drilled holes and a cavity, to which rounding plates C will be added symmetrically on both sides, which can be attached using screws 21 passing through special holes 22, or using an adhesive joint (Fig. 3). Also, the main part can be made of two halves by milling and the side plates are attached with glue, or milled immediately. Also, the device can be made by molding on injection molding machines from polymer plastics, in industrial production using standard equipment. In this case, the main structure will consist of two one-piece symmetrical halves connected to each other (Fig. 4).

The light guide lens-cover and small components such as a sliding platform-switch can be made by 3D printing from the corresponding types of plastic, or by molding the plastic. Elastic brackets are made in a standard way from spring wire, LEDs and batteries can be purchased from the variety offered on the market. Thus, this device can be produced both in small quantities and on an industrial scale, which indicates high manufacturability and commercial potential. The materials known from the prior art and available in the market conditions can be selected with the required characteristics and are easily applied for the production of the claimed invention.
