[0001]

[Industrial applications]

 The present invention provides a kind of chair-like function for supporting a human body in a slightly slanted position with the waist from diagonally below and supporting the back with the back in a comfortable leaned state. About parallel bar chairs. This parallel wheelchair is mainly used outdoors, and stands by so that it can perform a series of movements / work etc. immediately starting to move as required, or not to give others the impression of being lazy or slow. It is used to make required workers, athletes, etc. stand by in a standing position but in a comfortable posture.

[0002]

[Prior art]

 Various types of chairs are provided as furniture, tools and outdoor equipment that are closely related to daily life. There are a wide variety of applications, forms, materials used, etc., but they can be broadly classified according to the presence or absence of a backrest. With a chair with a backrest, it is possible to maintain a comfortable posture by not only sitting down but also leaning down. Other than this, the form naturally differs depending on whether it is fixed or movable, or whether it is for outdoor or indoor use.

[0003] By the way, conventional chairs have a seat plate part on which the buttocks are placed almost without exception, and they sit down on this seat plate, and at first glance, they rest. You can see that. This does not cause any problems in daily life, but depending on the situation, it may be evaluated as improper and may not be preferable. Generally, it is required for those engaged in the hospitality business to clearly indicate that they are always prepared for customer service. As an example, at a gas station (gas station), which is a service industry that performs frequent operations that require frequent movements, customers who enter the store irregularly even if there are no customers on standby. It is not desirable to show the person sitting on the chair as it does not give a good impression. Therefore, it is customary for the worker to stand without sitting down even when in standby.

Further, even if the above impression problem is eliminated at a gas station or the like, once a customer arrives, the worker must rush to start the work in a short time even when waiting. For this reason, it is not acceptable to prepare a full-fledged chair and sit down on the seat. It should be noted that the posture of directly sitting on the floor or crouching is not allowed for the same reason. Also, it can be said that leaning against the wall surface of a building or the like instead of sitting on a chair is a relatively comfortable posture, but it also makes a bad impression to the customer as described above, and generally from a work place such as a refueling facility. Even at a distant position, the service deteriorates, which is not preferable. However, it is not hard to imagine that standing for a long time puts a considerable burden on the worker. Therefore, reducing the load on the operator is also an important issue, and it is preferable to provide a state that is as easy as possible, especially during standby. At the same time, this will also lead to good results for improving the next work by the manufacturer.

[0005]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned circumstances, and can appropriately support a human body in an almost standing posture as if a chair is used, which allows immediate operation for the next work. It provides a comfortable and almost upright posture for workers while always maintaining the state of being engaged, and at the same time does not make other people such as customers feel uncomfortable, and it is a relatively free place. The purpose is to propose a new parallel bar chair that can be moved to and used.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the first invention of the present application, a pair of left and right flat plate-like ground board parts having a predetermined length in the front-rear direction and having a sufficient weight and a bottom surface in contact with the ground surface, and an upper middle part of each ground board part. A pair of left and right side supports that are substantially parallel to each other and have their lower ends fixed to the upper part and extend substantially vertically, and a length that exceeds the lateral width of the body supported substantially horizontally at the waist height of the human body between the side supports. A waist rod-shaped member, and a back rod-shaped member that is supported substantially horizontally in parallel at a position that is horizontally rearwardly offset from the waist rod-shaped member at a height approximately between the backs of both sides of the human body. Configure a parallel bar chair with.

In the second invention of the present application, an elastic coating material is wound around the outer circumference of the waist rod-shaped member. In the third invention of the present application, each of the left and right ground boards is provided with a tread plate portion having a predetermined width extending from the front end portion to the substantially central portion inward, and is configured to have a substantially L shape. Further, in the fourth invention of the present application, a fixing portion between the ground board and the lateral support member, both ends of the waist rod member and the lateral support member, and both end portions of the back rod member and the lateral support member. A locking means that is easily attached and detached is provided at each of the fixed portions.

[0008]

[Action]

 In the parallel bar chair of the first invention, a pair of left and right side supports extend parallel to each other and extend substantially vertically upward from the upper middle part of the ground board part and are separated from each other by a width exceeding the lateral width of the human body. The whole body is self-supporting in a state where the waist rod-shaped member is supported in parallel to the horizontal level and the back rod-shaped member is supported at a position shifted rearward at the substantially back height. Since this parallel wheelchair maintains the above-mentioned state simply by placing it on the ground or floor, it can be moved to any desired location and can be oriented in any direction. Therefore, for example, in the case of a petrol filling station, by pointing the road side at an appropriate place near the work place, the worker leans slightly from the front side of the parallel wheelchair and leans slightly, so that the lumbar region The bar-shaped member supports the buttocks obliquely from below, and the back bar-shaped member slightly supports the back, so that the user can stand by in an extremely comfortable posture. Moreover, there is no concern that the visitors will feel uncomfortable or uncomfortable, and they can immediately start the customer service work. In this way, it offers a comfortable posture while standing and the next swift action that could not be achieved with conventional chairs, and at the same time, there is no possibility of giving lazy impression to others.

Further, in the second invention, the buttocks are softly supported through the elastic covering material, which is more convenient to use. In the third invention, since the user's foot rests on the tread part and presses the parallel chair in the use state, it is possible to reduce the weight and the width of the front and rear of the parallel chair, and to design a compact chair. Further, in the fourth invention, the fixing between the main parts is made easy by the locking means, so that the parts can be separated and handled at the distribution stage for easy handling. In addition, even if it is in use, it can be disassembled for transportation to a slightly distant place, and can be reassembled for ease of use.

【Example】

 Hereinafter, each invention of the present application will be described with reference to the accompanying drawings and examples. 1 is a front view, FIG. 1 (b) is a side view, and FIG. 1 (c) is a perspective view showing a usage state. The parallel bar chair (100) of the illustrated embodiment is mainly composed of a pair of left and right ground board parts (10, 10), left and right side supports (20A, 20B), and a waist part supported between the side supports. The rod-shaped member (30) and the back rod-shaped member (40) which is supported substantially parallel to the rod-shaped member (30) are composed of four parts and six parts.

In the embodiment, the ground board part (10) is a substantially rectangular iron flat plate having a predetermined length and a sufficient weight in the front-rear direction, which is placed so that the bottom surface is in contact with the road surface or the ground surface. And a mounting plate made of a metal with a predetermined thickness and a rectangular shape that extends vertically upward with a fixed width in the front-rear direction, the lower end of which is fixed by welding at approximately the center of the ground substrate (11). It is composed of 12) and. The mounting plate (12) is provided with four mounting through holes (12a) at the top position of the quadrangle in the plate thickness direction. Then, the mounting plate (12) is extended substantially vertically in a substantially "V" shape and extends at a lower end thereof with mounting through holes (20a) at positions corresponding to the mounting through holes (12a). A long plate-shaped lateral support (20A) or (20B) is fixed with bolts and nuts (14, 15) using the mounting through hole (12a) and the mounting through hole (20a).

The side supports (20A, 20B) are formed in plane symmetry, and each of the above-mentioned "L-shaped" bent portions is substantially at the waist level of the human body and the first locking means ( 13b), and a second locking means (13c) is formed at a position which is shifted rearward in the horizontal direction at the upper end of the body approximately at the back height. In the embodiment, the first locking means and the second locking means are short pipes of a predetermined diameter fixedly fixed to the above positions by welding (or press fitting, screwing), etc. A hole is provided.

The waist rod-shaped member (30) has a proper length (W) that exceeds at least the lateral width of the human body, and is made of stainless steel having a predetermined wall thickness with an inner diameter adapted to the outer diameter of the short pipe that is the first locking means (13b). Through-holes are formed at both ends of the pipe as locking means (30a) corresponding to the screw holes of the short pipe described above at positions facing the end-side cylindrical surface. The material may be a metal material other than stainless steel, such as iron. Also, the back rod-shaped member (40) has the same length (W) as the waist rod-shaped member, and has a predetermined wall thickness of stainless steel or other appropriate material with an inner diameter that matches the outer diameter of the short pipe as the second locking step (13c). In the metal pipe, the both ends are provided with through holes corresponding to the screw holes of the above-mentioned short pipe on the end side cylindrical surface as locking means (40a). The waist bar-shaped member (30) and the back bar-shaped member (40) may be used as they are, but may be coated or the like, and may be treated with a resin or the like.

From the outside of the through holes at both ends of the waist bar-shaped member (30) and the back bar-shaped member (40), through the bolts, screwed into the screw holes of the respective locking means and tightened to the right side. The support body (20A) and the waist bar member (30) are firmly fixed. Exactly the same way, the side support (20A) and the back rod-shaped member (40) are firmly fixed by screwing bolts into the screw holes from the outside of the through holes and tightening them. The waist bar-shaped member (30) and the back bar-shaped member (40) are firmly fixed to the left side support (20B) in exactly the same manner. As described above, in the parallel rod chair of the embodiment, since each main component is provided with the locking means and all the parts are screw-coupled, it is supplied in a disassembled state in the sales / distribution channel and used. A person can easily assemble and use it at the place of use. It is also easy to disassemble and move again.

The parallel rod chair (100) of the embodiment in the assembled state is used by placing the ground board portion (10) downward on the floor surface, the ground surface, or the like. As a matter of course, the person is self-supporting as it is, but as shown in FIG. 1 (c), a person can lean forward from the front and properly support the waist and back. At this time, the waist rod-shaped member (30) supports the waist of the human body obliquely from below, and the back rod-shaped member (40) lightly supports the back of the human body. This parallel bar chair has a sufficient weight, and even when a human body is supported, the overall center of gravity is always located in front of the rear end of the ground board of the parallel bar chair. Since it is designed properly with consideration given to it, it will not fall or move backward in the above-mentioned use state. In this way, the worker etc. can stand in a comfortable posture similar to that when using a chair. You can easily move it to any place by lifting it.

In the parallel rod chair of the present invention, the height of the waist rod-shaped member (30) (Hh: see FIG. 1 (b)) and the waist rod-shaped member of the back rod-shaped member (40) are adjusted according to a person having a standard physique. The amount of rearward shift (D) and height (Hb) with respect to (30) are determined. In addition, the width (W) is determined so that a person with a standard physique can lean comfortably between the lateral supports for the one-person type. In the case of two people, a size is adopted that allows two people to lean side by side with ease. FIG. 2 shows an example of suitable dimensions for a parallel rod chair for one person, and FIG. 3 shows a specific example of dimensions suitable for a parallel rod chair for two people in front and side views. Of course, these dimensions can be changed slightly according to the situation to reflect the requirements.

In addition to corresponding to these physically required dimensions, the weight balance and the position of the rearmost end of the board should be taken into consideration in consideration of the safety factor so that the user will never fall or move backward in use. The size (and hence weight) of each remaining part is determined. The specific dimensions of each part shown in FIGS. 2 and 3 above were determined by reflecting the weight distribution and the results of mechanical analysis in this way, and are examples of numerical values that sufficiently match the intended use. is there. In addition, it is preferable that this parallel chair can be used by one person or two people at the same time, and it is possible to make it even larger, but it is difficult to move due to difficulty in moving and it is unexpected. It is not preferable because it increases the risk when a situation occurs.

Next, FIG. 4 is a perspective view showing another embodiment of the parallel rod chair of the present invention. The waist bar member (30) of this embodiment (200) has an elastic covering material (31) wound around the outer periphery of the central portion. As the elastic coating material (31), for example, a rubber material or a sponge wrapped with synthetic leather may be used. As a result, the user does not feel pain in the buttocks even after long-term use. The other parts are exactly the same as those shown in FIG. 1 and their explanations are omitted. Similarly, an appropriate elastic covering material may be wound around the back rod member (40), which is suitable for long-term use.

FIG. 5 is a front perspective view showing still another embodiment. In this embodiment (300), the portion of the back rod-shaped member (40A) against which the user's back rests is curved rearward. That is, the back bar-shaped member (40A) is curved backward to form a concave shape at the site (40b, 40b) that supports the human back, which allows the user's back to be supported evenly and for long hours of use. However, it can be used comfortably without damaging specific parts of the back.

In addition, in the parallel rod chair of FIG. 5, each of the above-mentioned left and right ground boards (11) is provided with a step board portion (11a) of a predetermined width extending from the front end portion to the substantially central portion inward, and is substantially L-shaped. This is a miniaturization of the parallel bar chair as a whole, and when used, the user's foot naturally rests on the tread (11a) and part of the weight causes the ground board (10) to As the result is to hold it down, the weight can be comparatively light as long as each part has sufficient rigidity, and it will not fall down during use even if the amount of protrusion of the base plate to the rear is reduced. Therefore, it can be used sufficiently stably even if it is made smaller and lighter.

The parallel rod chair of the present invention has been described above with reference to the embodiments, but the respective parts are not limited to the embodiments, and various modifications can be considered. For example, the waist rod-shaped member or the back rod-shaped member may be a round rod instead of a pipe. Correspondingly, a simple through hole is used as the locking means of the lateral support, and a central end face portion is used as the locking part of the rod-shaped member. A screw hole may be provided in the side support body so as to be screwed into the screw hole from the outside of the lateral support body using a bolt. Further, a synthetic resin pipe or round bar having sufficient strength can be used instead of the metal material for the rod member. The substrate and the lateral support may be fixed to each other as long as sufficient strength can be expected, for example, by welding. However, in this case, disassembly becomes impossible and usability deteriorates.

Since the parallel chair according to the present application can be easily moved, it can be used at any place depending on the situation. In addition to its original purpose, it is easy to move and has a horizontal bar with an appropriate length, so that the entrance to the facility is closed when the gas station is not in use, such as when it is closed. You can use it instead of the gate by moving and placing it like this. In addition, although a gasoline filling station was mentioned as an optimum example of the application of the parallel rod chair of the present application, the parallel rod chair of the present invention is not limited to such an application and can be used in various fields. Although the player will have to wait for a while during practice or games, the parallel chair of the present invention is suitable for a short waiting time because it can maintain a comfortable posture without sitting down and can move immediately.

[0023]

[Effect of device]

 As explained above, the parallel bar chair of the first invention of the present application is a flat ground board part having a predetermined length in the front-rear direction and a bottom surface contacting the ground surface with a sufficient weight, and an upper middle part of the ground board part. A pair of left and right side supports that are substantially parallel to each other with their lower ends fixed to each other and extend substantially vertically, and a length that exceeds the lateral width of the human body that is supported approximately horizontally at the waist height of the human body between the side supports. The waist rod-shaped member and the back rod-shaped member that is supported substantially horizontally in parallel to the waist rod-shaped member at a position substantially horizontally behind the human body between both side supports at a position shifted rearward in the horizontal direction. Since it is configured, it provides the operator with a comfortable posture while standing, and can take swift action when necessary. In particular, since there is no fear of giving lazy impression or discomfort to others, it can be used by a worker in the service industry, which is preferable.

Further, in the second invention of the present application, since the elastic covering material is wound around the waist bar-shaped member, the buttocks are softly supported and further comfortable to use. In the third invention, the left and right ground substrates are provided. In addition to the above-mentioned effects, in addition to the above-mentioned effects, the user's foot rests on the tread part and holds down the parallel chair in use, since each has a tread part with a predetermined width that extends from the front end to the approximately central part inward. The width of the front and rear can be reduced to reduce the size and weight of the parallel chair. In the fourth invention, the above-mentioned ground board and the side support are fixed to each other, the waist rod-like members are fixed to the side support to each other, and the back rod-like members are fixed to each other to the side supports. Since the locking means is provided at each of the respective locations so that the parts can be easily attached and detached, in addition to the above-described effects, each part can be in a separate packing form at the distribution stage, which is easy to handle. It is convenient to use because it can be disassembled when the user moves it to a remote place or stores it.
